But before the patch I could see the player's current in-match rating underneath the shirts on my PC monitor, but since the patch I can't see any.
I assume it's got something to do with the width of the monitor? They must have reduced the space for the ratings now, so smaller monitors can't display them now.
All in all, so far, so good with this patch. One "minor" gripe. Started a fresh save file with Portsmouth in administration. two things:
1) Is starting to annoy me receiving agent offers for players when I'm still under a transfer embargo. I can't sign anybody, at any price, so why do I still get offers?
2) Every 4 weeks it seems, I'm getting the "restructuring debts" news, and even a new CVA. I understand FM levels out finances, but still...I need a tycoon quickly!
and it didn't help with my game freezing up almost every time i hit continue...
I don't use any custom skins, but do have player pictures, logos and kits..... Any suggestions?

So again what's up with French teams having no money?
delete mistake on my part
I have just had a massive problem occur on my first game on the new patch. I have two players loaned out at other clubs who are underachieving or at least doing badly. I am playing as Wolfsburg and the players are Tuncay at Bolton and Ja-Cheol at Augsburg. They have just come to me complaining about the club underachieving. Before the patch came out they obviously would've gone to their current clubs rather than to me about this. I don't want relationships with my players or their future interest in them staying with me after loan periods to be destroyed due to this. Has anyone else reported this? Is it in the process of being fixed? Do you need screenshots? If you do need them how do I take them and post them on here?
David de gea is traveling on the day of the community shield, he played IN the real community shield
Also just had Diego come to me with the same complaint when he is on loan at Atletico Madrid and has nothing to do with my team currently
Big issue for MLS:
Prior to the patch, the game would recognize when you no longer had any Designated Player slots available to offer players. Players/agents wouldn't ask for DP contracts if you weren't able to offer them one. Post-12.2, however, I've looked at two players on my team to enter contract negotiations with (to extend their current deals.) Despite already having 3 Designated Players on my squad, each player is asking for a DP contract (which I'm apparently able to offer- I'll do a quick test to see what happens.) One player is "waiting to see what I offer" and, when I select the first wage available to offer him, it reads -$83 per year. Yes, he'd be paying ME to play!
Update: received a news item stating that I couldn't renew the contract due to DP limits. Noticed a handful of players asking for DP contracts if I approach them to extend their contracts...and quite a few others that are suddenly asking for bonuses to be included in their contracts, which had never happened before the patch (now in 2018.)
Please, please let there be a way to remove this patch, or else my game is ruined!!!

One more question I forgot earlier.... Have other players noticed their news feeds having insane amounts of useless information? It's almost like checking my old hotmail account when I saw spam everywhere. I would estimate that I received around 20-30 new messages each time I click "continue" and very few have anything to do with me. I've reduced the settings to the minimum possible including turning off international team news and any competition that I am not in but am still receiving crazy amounts.
might be against the mold here but can i ask for a non steam version to be available next year... ive had nothing but problems from this years version.. put aside the problems with the last patch but this patch i was playing offline, noticed the new patch.. quit game and went online... downloaded patch.. waited.. went offline.. couldnt start game.. restarted machine.. chose to go online.. started trying to download steam.. stopped right away.. said steam was unavailable, after restarting numerous times it then started the download for footy manager again.. so frustrating
im now downloading for the second time.. unknown to wether this one will work
wish we could register to validate our copy then download the patches individually... far less problems this way
i hate that, transfer deadline day spam, where some team you have never heard of signs some player you have never heard of.
Don't know if this is right section to post, but...
Is it me or since 12.2 something happend with scouts reports??? I mean-there's none. Player appear to be scouted-but no report is present. Just blank page saying that "you need to ask your stuff to scout etc." ,wich has been done and stars are there! Bug? Or am i missing something?
Thanks for answer.
There is a space before the "M" in Melbourne Heart FC which means their name always appears shifted to the left one space. It's quite annoying once you see it. Easily sorted in the Editor. Sadly, I started my game before I knew of this.
I am finding the whole patch to be weird tbh. I was just fired from Wolfsburg for being in mid table at the end of October with no warnings. We've played not even half a season and tbh the team usually finishes mid table IRL and the objective was only Europa League. We had a slow start losing 4 of the first 5 games (other game was a win) but since then have been awesome beating the likes of Werder and Hamburg and hadn't lost in ages. Then we slipped up vs Dortmund away only going down 1-0 (not bad considering how awesome their squad is on FM compared to mine) and was fired. This type of thing never used to happen before the update, especially considering I had my reputation as former German international, which always seems to guarentee time to turn things around if you have a bit of a slow start.
The issue is a big one since we (people that manage a Greek Superleague team) cannot continue a previously saved game, we have to start a new game! The problem is that the new patch doesn't treat EU nations as EU for the Greek Superleague. Does SI know something about EU kicking out Greece from EU?
Anyway, I personally don't want to just start a new game, and I am sure a lot of Greeks just want to continue playing their old saved games! Is there any possibility to have the option to move back to the 12.1.1 patch or re-release it? A lot of us we were happy with just that...
Scouting cost is completely out of wack in BSP england after the patch. I went from 25K per year to 135K per year without changing any scouting assignments from previous season. The patch got installed with 1/3 of the season to go and it is costing me 36K per month. It's my main expenditure right now.
Two scouts assigned to roam UK&Ireland with Maidenhead in BSP
Have some problems I found in the k-league regarding transfers.
After looking at Jeju United they are still missing the Australian centerback Adrian Madaschi.
On a side note Junior Santos who was one of the top goal scorers on Jeju and in the k-league last season is still just as horrible as in fm 2011, I was hoping this would have been fixed in 2012 but just seems to be ignored....
Hoping some one can can at least take a look at this would make the game that much better!
i just left my game as i was about to shut down my computer and saw that there's a 974.8kb update. any idea what its about?
I actually feel some tranfers are a little unrealistic after a couple of seasons, for example Lens spending 10 million euros on one player.
BTW, I've just been promoted with Tours to Ligue 1 in 2015 without buying a single player (only free transfers)!
new update has made match engine speed go really slow (even on highest speed). Any advice??
Any update regarding the problem with the Greek League?
What exactly has this patch changed?....
Yes, I've read the 'change list' thing but to be honest, I've played for just over two hours under the new patch and apart from my BSN scout costing me 4 times what he used to cost me I can't see any difference what so ever (yet). The transfer market still sucks and no-one buys any players off you, I've just had 6 first team players go out for very long periods before the season even started, freekicks, throw-ins, crosses and control of the ball near the touchline are all still crap and fullbacks still wonder out of position........ Was it really worth the long wait?
Is there any way of going back to the previous patch? At least then I wont end up bankrupt through over paying for scouting.
I assume there is no way to take the update without the patch right?
I can't open the editor any more it goes green on start up and you can see a picture of someone holding a ball in the background but its all grren like grass and I can't load any thing up this has happen since stream update today.
FTP details here - http://community.sigames.com/showthr...P-Instructions
Also make sure you're not running any custom graphics/skins to make certain it's not those causing it. Then make sure you're running the latest graphics card drivers for your graphics card. Let me know if any of this helps.
I have downloaded the patch, but things like flags, player images, the kits on the tactics page and even players that don't have pictures the grey silhouette aren't appearing.
Any help would be grateful!
Then make sure that when the game loads up, in your in-game preferences that 'use skin cache' is ticked under display and sounds.
I expected to be ignored, or get a patronizing request to upload a save game they won't look at! Last 5 years have made me cynical, like posting two years ago about Man Utd picking a reserve team to play in the champions league semi, and still doing it now! AI managers are shot to bits.
Like i say i do agree with you guys its no secret the AI needs a massive revamp we'll just have to see what fm13 brings, but if im honest i dont think its something SI ignore
No acknowledgement or changes in the last 5 years? Have you guys been in a coma or something? When you say things like that it instantly gives the impression your just throwing the toys out the pram. There have been big changes in the last 5 years in the ME and the entire game and SI have acknowledged on several occasions that the ME has certain weaknesses, which is why they are replacing it. If your not aware of that despite being a member on here for 9 years then you will never notice when they make an announcement on it.
I can bet almost 100% you guys will buy next years version no matter what you say in this thread.
So-nobody have problem with scout reports? Is it bug or not?
Some suggestions? Please?
Wally, I know what your saying, Jon is right though, we do hear "being looked at for the next version" every year, and new game arrives and its still a complete pickle (sound like me sadly departed Grandma, lol). All the moral tweeks just make the problem worse. Game code on New patch seems to making no allowance for a new appointment, so new manager takes over and straight away you get rubbish news reports he is on the verge of the sack, at a club expected to struggle. Forget PA/CA changes for players, as unless you sign them, they spend there career roting in the reserves, Jack Wilshire for last 3 FM's for example, whilst the AI continues to play 38 Rosicky!
Milnerpoint, we are raising a valid point that you can't be bothered to read! We know the ME is changed every year, we aren't arguing that, we are talking about the AI of the Managers and clubs. No chucking toys out, so before flaming, read what has been written please!
Yeah Milner, read
Edgar, it ended up in here as the sackings and insecure status of new manager's seems to be worse since the patch was released. Like I said above, that Milnerpoint also missed, I will be buying FM13 in the hope it has been given a massive overhaul, but if it hasn't it will be my last FM game.
Just downloaded the patch,no problems at all,but checking out my favorite club AFC Bournemouth,no Russian bussinessman even as a director,Maxim Demin,oh well will have to get the info and put him in myself and change captain to the right one
I'm Having a few issues since the patch...
Firstly I'm finding the game hangs alot when coming out of processing to the news screen. I have a very high spec machine not lacking in CPU, graphics or RAM and the game ran all leagues like a dream before the patch.
The second issue i'm having is some weird player happiness issues. Take the below example:
Sunday he loves the club, Tuesday he wants out!
Uploaded with ImageShack.us
I don't get none. Player appeared to be scouted but no scout report is there. It ether saying it's in process of scouting and shortly will be presented or that i need to send somebody to scout (and i've already done it and player got his stars-but no report is there..) ?!
I´m planning to start a very long term game. But I´m wondering if I should wait for a hotfix or not... What do you think?
I have the same problem with scouting as Dinamo_K - no reports are visible, it just says that I need to request a member of scouting staff to compile a report, even though I just scouted the player and he has the recommended stars next to his name. That's the case for any player in the game no matter what country/league/club they're from (coach reports are working for my players) - I'm playing ManU, first season with over 40 leagues playable.
i see what people mean about injurys too.. after starting a new game i have played 3 matches.. and had 4 injurys.. the opposition has had the same amount too... way to frequent imo
local disk/user/your name or what ever the user name is under/app data/roaming/sportsinteractive/fm12/ then delete the cache folder in there
I only downloaded FM2012 yesterday via Steam with the new patch. I played the demo and I noticed plenty of bugs which is why I waited.
But I have notice something and I know it didn't occur in FM2011, but it has been picked up on this thread: http://community.sigames.com/showthr...-player-search
As you can see, I explained the problem I had with this 'player search' issue and I do hope it is a bug and something that can be remedied. To save ppl having to open the posted link, this is what I explained. If anyone can explain this, thanks in advance:
I (first) noticed this issue on my first search for a player: I couldn't remember how to spell his name but I obviously I knew his position (right back), and I knew he was French and under 21, so I naturally performed the search with these criteria added and only around 20 French under 21 right backs were shown, none of which were the player in question. On various incarnations of FM I would see thousands of players under this criteria. So where was this player, whom I easily located and bought on FM2011, disappeared to?
I eventually managed to spell his name correctly and performed a search in the text box at the top right of the FM2012 screen, and there he was. So how can a player exist only if you know his name?
I have been reading the thread to attempt to understand whether this is something that has been purposely implemented in FM2012, or whether it is a flaw. If the reason is because of player knowledge levels, this still doesn't make any sense when I have a French scout with 100% knowledge of French players.
And if I perform a search for Brazilian right backs, for example, I got a list of over hundred, yet I have no scout with knowledge of Brazilian players.
When I chose my league selections at the beginning of the game, I always choose a huge database with many global leagues giving me a maximum limit of 75,000 players. Yet if I perform a generic player search without any criteria, it lists around 25,000 player. Where are the other 50,000 players that should be on my database??
I always rated the players search, and transfer scouting system of FM as it's best feature. I could spend hours manually sifting through players looking for the next big unknown star. Yet now, that part of the game has been taken away in FM2012.
I do hope this is just a error that can hopeful be repaired/patched, because it surely has diminished my enjoyment before I have even kicked a ball?
The conlusion: SI crew are eather incompetent (since regulary member solve the problem easily) or lazy (dont bother).
He must be too busy counting his mountain of gold......
@ bullybeef
The player search functions is merely an overview of the players your scouting network are aware of & that is why you are not seeing every single player, the key phrase that you'll see on the player search page is 'x players found in your scouting and knowledge range'.
IIRC it's more or less followed the current model since FM09 & has over time been refined to be linked more tightly with your scouting tools, just send folk out to scour the globe & watch the player count rise.
I've just downloaded the patch and everything seemed to work out well 'til I noticed that the "watch" in the left hand corner had disappeared. Have anyone else got this problem? Please, anyone, help me out because I am suicidal at the bloody moment!
I have had 2 issues with allocation money not being received in the MLS since the patch. The first happened when I won the league and was supposed to be awarded $150,000 for qualifying for the NACL. As you can see below this somehow brought my total allocation up to $0. That just doesn't add up. The second issue was after selling a player. Although I supposedly received an allocation amount of $230,000 for the transfer my allocation totals stayed at their current value. While neither of these are massive values they are certainly significant for the MLS and I'm now afraid to sell any other players.
I have screenshots of each however they only show what I explained. Let me know if there is something else that I can provide to help.
So-maybe somebody from SI team will be kind enough to treat problem with no players reports available???!!! It's really annoying not to be able to use this important (in my view) feature.
my first game both my strikers got injured (beattie & evans)
evans out for 4-5 weeks
second game hoskins (in for evans) gets injured out for 2-3 weeks
3rd game Baxter (in for hoskins) injured
Are you using a third party skin? If you are then it might not be compatible with 12.2.
I'm not seeing the issue you've described while using the default dark skin.
If not, is there any chance you have a save game from before either of these events occur?
Edit: Actually, (it didn't sound like it, but) are you managing one of the Canadian teams by any chance? If you were, this would explain why you didn't get any allocation funds for winning MLS Cup.

Just started a new game on the new patch, everything seems to be running ok. The only gripe i have is if a new patch or a hot fix is brought out in the next few days going off the problems people are having i will no longer have the german national side (real players) and will have to start the whole game again and delete the inc files... would i be right in saying this??
It seems like Steam wont download the new patch. It says "Download starting…" but nothing happens. It has been that way since yesterday. When I try to run FM2012 I get the message "The Steam servers are currently too busy to handle your request. Please try again in a few minutes".
Any ideas what's wrong. Really frustrating, and have never had this problem before…
I have saved games before both events. The first event (winning the league and qualifying for NACL) has a save game just before the championship match and so will require winning the match. The other save game is about 15 days before the transfer goes through however the league is in offseason at this point so not much happens between. Where and how would you like me to upload these save games?
EDIT: Nope, not playing as a Canadian team. I'm playing as the Red Bulls. I just had a coach headhunted away with better wage promises and, according to the alert, should have had 2/3 of that fee go towards allocation as well. Once again, though, the allocation budget stayed steady at 350,000 (where it has been since the season ended).

Yes you've hit nail on the head why did't we think of this are you listening BrockFanboys will allways use sarcasm when they dont have any rational arguments left.He must be too busy counting his mountain of gold......
I did not miss anything. I m fully aware the magnitude of the problem, but this is the fix which SI could easy implement while they are making new ME. This fix is better then the situation as it is right now. The fact that AM doesnt track back has been well knowed for 4-5 years. Humane managers can solve this with specific man marking, while the AI cant. So the biggest problem is for AI, which this fix solve with easy. They could do many things to fix this problem without cheanging the ME, but they didnt...and that is the fact.Well done on missing the point of the thread, its still only a temporary solution (albeit a good one) , as it doesn't fix the lack of tracking back from the AM bands for the AI, or the lack of balance in the MCs, both of which can only be fixed via the ME being overhauled.
Thanks Barside, I appreciate the reply. I am curious that I didn't seem to notice this in either FM09 or FM11 (didn't play 2010). Obviously I thought it was typically ironic that out of all the players I search for and that my Scouts were aware of, the first player I searched for (like I said, a French under 21 international) wasn't displayed even though I had a French scout with 100% scouting knowledge of French players. Yet I had a wide knowledge of Brazilian players yet I have no Brazilian scout.
Like I said, on FM2011 I used to sift through thousands of under 18 players in various positions yet I am lucky if I see over a 20 youngsters to scout in a specific position now. It does seem this feature has diminished the ability to discover a raw, unknown talent.
I currently managing Liverpool, and I couldn't imagine the current LFC manager asking his scouts for a list of French right backs and him only receiving a list of 20 odd players to scout. In comparison to FM2011, it seems this has noticeably and significantly changed.
I am a fan of the game but there should be a hotfix tbh. Apart from the bugs mentioned in this thread researchers from the Arsenal and Chelsea data have accepted they made vital errors. With Arsenal the injury to Thomas Vermaelen should not have been included as he was fit at the start of season which was acknowledged and also a mistake from one of the Chelsea researchers who wrongly set a retirement for Sam Hutchinson and therefore forgot to remove this from the game and he is not included unfortunately.

A neural network is a class of computing system. They are created from very simple processing nodes formed into a network. They are inspired by the way that biological systems such as the brain work, albeit many orders of magnitude less complex at the moment.
They are fundamentally pattern recognition systems and tend to be more useful for tasks which can be described in terms of pattern recognition. They are 'trained' by feeding them with datasets with known outputs.
As an example imagine that you are trying to train a network to output a 1 when it is given a picture of a cat and a 0 when it sees a picture that is not a cat. You would train the network by running lots of pictures of cats through it and using an algorithm to tweak the network parameters until it gave the correct response. The parameters are usually a gain on each input and a weight on each node as well as the actual structure of the network (how many nodes, in how many layers, with what interconnections).
Recognising cat pictures is actually a quite complex problem and would require a complex neural network (possibly starting with one node per pixel). A usual starting point for experimenting with neural networks is to try and implement simple logic gates, such as AND, OR, NOT etc. as neural nets.
Neural networks can be a very fast way of achieving a complex result. They are very interesting for AI research because they are a model for the animal brain.
One of the major disadvantages of neural networks is that it is very hard to reverse engineer them. If your network decides one particular image of an elephant is actually a cat you can't really determine 'why' in any useful sense. All you can really do is try training/tweaking the network further.
Neural networks tend to be used for well-bounded tasks such as coin/note recognition in vending machines, or defect spotting on production lines.
The best place to start if you are interested is probably to google 'perceptron' which is the name for one of the earliest neural network elements.
I study artificial intelligence in a masters program, and we use neural networks quite a lot. They are actually quite useful.
I think the problem for neural nets are their name. This both confuses what a neural network actual is, and makes some people question their merits because they expect them to act like brains, when they are really a fancy type of function.
The best way to understand a neural net is to move past the name. Don't think of it as a model of a brain... its not... this was the intention in the 1960s but its 2011 and they are used all the time for machine learning and classification.
A neural network is actually just a mathematical function. You enter a vector of values, those values get multiplied by other values, and a value or vector of values is output. That is all it is.
They are very useful in problem domains where there is no known function for approximating the given features (or inputs) to their outputs (classification or regression). One example would be the weather - there are lots of features to the weather - type, temperature, movement, cloud cover, past events, etc - but nobody can say exactly how to calculate what the weather will be 2 days from now. A neural network is a function that is structured in a way that makes it easy to alter its parameters to approximate weather predication based on features.
Thats the thing... its a function and has a nice structure suited to "learning". One would take the past five years of weather data - complete with the features of the weather and the condition of the weather 2 days in the future, for every day in the past five years. The network weights (multiplying factors which reside in the edges) are generated randomly, and the data is run through. For each prediction, the NN will output values that are incorrect. Using a learning algorithm based in calculus, such as back-propogation, one can use the output error values to update all the weights in the network. After enough runs through the data, the error levels will reach some lowest point (there is more to that, but I won't get into it here - most important is over fitting). The goal is to stop the learning algorithm when error levels are at a best point. The network is then fixed and at this point it is just a mathematical function that maps input values into output values just like any old equation. You feed new data in and trust that the output values are a good approximation.
To those who claim they are failed: they aren't. They are extremely useful in many domains. How do you think researchers figure out correlations between genes and diseases? NNs, as well as other learning algorithms, are used in bioinformatics and other areas. They have been shown to produce extremely good results. NASA now uses them for space station routines, like predicting battery life. Some people will say that support vector machines, etc are better... but there is no evidence of that, other algorithms are just newer.
It is really too bad people still make this claim that neural networks are failed because they are much simpler than the human brain --- neural networks are no longer used to model brains --- that was 50 years ago.
It is a mathematical scheme for building a equation (taking multiple numerical inputs and providing a single numerical output) with adjustable coefficients weights. There are algorithms that can adjust the coefficients to make the equation approximate the expected outputs, given a training set consisting of inputs and expected outputs.
The simplest example, along with graphics, is available on Wikipedia. This example is known as the XOR.
In simple words, like you asked, Neural Network is a failed idea of mimicking biological neural nets. It never gave any interesting results and will probably never do, because:
(1) it is too simplistic compared to what you can do with any Turing-complete programming language
(2) it is too simplistic compared to biological neural nets: they turned out to be more complex than it was thought by the time the NN theory was created.
Any claim that neural nets are successful in any task used in real world applications is an exaggeration.
Come on downvote me.

can anyone give a realistic estimation, based on real-world experience, of how much biometric authentication techniques are being used in the IT field?
As I'm sure I posted in one of the other biometric questions, the only places I see it a lot are datacentres. And more specifically, datacentres protecting high value root certs. For this type of environment it is the norm, rather than the exception. Update to say - it is only ever used in addition to all the other controls, not instead of!
Elsewhere, it's patchy - people are starting to use fingerprint scanners on laptops etc., but I get the impression that is just because they are there so might as well be used:-)
Over the years I've seen commercial organisations evaluating biometrics (e.g. voice) and limited deployments (e.g. fingerprint readers on pcs), but it's very rare in my experience (which is mainly with financial and large asset management organisations).
I think the main reasons biometrics have not got very far are:
The reason for (2) is that any biometric system digitises some human characteristics, and the resulting bunch of bits is by definition not secret and eminently replayable. Thus one must trust the sensor and all the communications with it. This is almost impossible to achieve outside of a physically secure environment, and actually impossible to achieve without physically secure sensors.
Furthermore even given a physically secure sensor one has to be sure that the sensor is reliable against errors and impersonation attacks. For example a fingerprint sensor must be able to tell that the fingerprint it is reading is actually alive and attached to the person, and also not a fabricated replica :-)
I work in the biometrics security field for a government contractor. I can't get into specifics of who uses our products and services for security and non-disclosure reasons; but it's used by a wide variety of government, military, law enforcement and private organizations.
We can provide SDKs so people can develop their own applications which interface via drivers to the hardware; or they can use our solutions for software along with the hardware.
There's many different forms of biometrics in both portable and stationary forms, all which range from iris/retina scanning and fingerprinting to much more. (Again, sorry I can't go into details.)
PS - Ubuntu has biometric support built into it, but none of our customers ude that, to my knowledge.
Fingerprint scanners have become more common since they became so cheap. Several years ago they were included in nearly every laptop on the market. They're not so common anymore, though, presumably because people never used them.
Most of the top-tier datacenters I've visited have had some sort of biometric scanner at the door -- usually hand geometry -- though I rarely see biometrics entering any other type of building. As a rule, facilities built or upgraded from around 2000 to about 2007 will often implement biometric security. Some new places still do, but it's not as in vogue as it used to be.
There's an important point about biometric authentication that many of the commercial installations respect, but which is not immediately obvious: you should never rely on biometrics to supply both authentication and identification. Biometric measurements are useful, but they're in no wise unique. Two people may not have the exact same fingerprint, hand geometry, or iris patterns, but the measurements are often lossy enough to allow for collisions. Biometrics need to be just one part in a multi-factor authentication system.
I'm not sure that any single person could answer this one - I get the sense that we all work in different industries, so there's probably no one right answer. I'd bet that if you hit the right niche, the answer is "of course, we use it everywhere" but many other industries would say "it's an interesting idea, but we don't use it."
I'm certainly in the "it's an interesting idea, but we don't use it" camp. I do a lot with PKI, but then that's my career. I've been in several cases where I've heard of biometric access controls in some other system that someone I knew used, but it always seems rare and far away.
If you are asking about "how many different technics, such as fingerprint scanning, retina scanning, hand scanning, ear scanning etc.", then I think I named them all.
If you are asking, how widespread the use of biometrics is, then I'd say "not much" mainly due to lack of uniform APIs that would work as a bridge between user applications and hardware. Each hardware vendor has it's own set of APIs. There exists BioAPI, but it lacks some important (for programming) things such as lack of encryption mechanisms (simply answering "this person is 99,99% the one he claimed to be" is not enough in many scenarios).
However, with growth in demand for two-factor authentication, biometric solutions should gain more important role, maybe via some scanners built into smart devices. But that's I'd say 2-3 years away from now (at least).
The most consistent biometrics implementation that i see is for datacenters. Aside from a smaller lab, all the datacenters that I have dealt with require some level of biometrics, mostly hand scanners.
Again, this is purely my experience. Other than that, biometrics seem to be underutilized in the corporate environment. I think it would be amusing to see how many people jump on the biometric bandwagon if there was some integration into LDAP or AD (wait... is there?).
One thing I didn't see mentioned is using fingerprint scanners to prevent time-clock fraud. This has significant takeup with some of the largest players in retail and timekeeping adopting it. I'm not sure the actual percentage but I've seen them all over the States. The vendors' argument is that they prevent thousands to tens of thousands in time-clock fraud a year vs what they cost. Work reliably enough in practice so I'd say it's one of few success stories for biometrics.

What is the correct te-form of 問う? Is it 問って or 問うて or both?
Sign up

While 「問って」 may seem the logical conjugation, 「問う」 is actually irregular (see the Wikipedia entry for 不規則動詞). According to this article, 「問って」 is "almost never used". It appears therefore that 「問うて」 is correct in modern Japanese.
In case you are wondering why, the author of the latter article hypothesizes that this irregular conjugation makes the dictionary form of this verb more obvious when using its te-form in speech (as well as others, such as 「乞う」).
One contributing factor is that the pronunciation of the dictionary form (問う) can be thought of as one long vowel syllable (トー), so conjugating it as 「問って」 (トッテ) would result in the modification of that identifying first syllable.
Of course, this reason alone would not normally be sufficient justification for this irregularity. The author adds that due to frequent substitution of 「問う」 with 「頼む」 in modern Japanese, 「問う」 is now less common and thus requires extra disambiguation when used in the te-form.
問う has a hidden sound "w" at the end of the verb stem, which does not arise at the surface in nonpast forms due to a phonological rule that deletes "w" in front of vowels other than "a". 買う is another such verb:
So for the te-form, you would expect gemination, which happens with other verbs ending in "w". However, as written in the wikipedia link that con5013d cites, This verb is irregular, and the form


text: Since there is a part two coming out for Cloudy with a Chance of Meatballs, I thought making a new lesson on "how to draw Sam Sparks" would be something that people would like. Besides, she looks a bit different in the sequel than she did before. Sam is Flint's love interest and vise versa. She is a weather girl or t.v. reporter that is still taking the news as Flint, Earl, Brent, and Sam explore what happened to Swallow Falls after the incident with Flint's weather invention. Needless to say everyone on board will become speechless when they see the repercussions of Flint's machine. Drawing Sam Sparks will be as fun as the first time but better because this is an easier lesson to follow. Enjoy and stick around.

Elektra Mou (My Elektra) Ortho transparency and color duraclear transparencies 16 x 12 feet 1994
My daughter, Elektra, died at the age of 5 years, 5 months, of Stage IV (metastasized) neuroblastoma. She lived one year, one month after her initial diagnosis of cancer on August 10, 1992.
This piece is a photographic narrative. It begins with Elektra in a photograph taken when she was well (passport photo) and ends with a another photograph of her when she was well, floating in the bathtub. This represents Elektra coming full circle to a place I believe she is currently in, a place without pain.
I cannot stop my need to help and educate the public on illness and death. This work will continue to be about cancer and its visual expression as demonstrated by a mother who lost her child to a terrible, progressive disease.

I was watching the Olympics today and happened to catch track cycling (sprint). I understand that they have fixed gear bikes which is a reason they start slow, however, I did not understand why they did a lap or a little more at a very slow pace, then proceeded to pick up the pace for the second lap, and finally sprinted on the last lap instead of just going full out from the get go? What is the strategy behind this?

They don't start slow because they are on a fixed gear (track) bike. They start slow because they are trying to coax the other rider into starting the sprint for the finish line before they do. The advantage is typically given to the rider behind the other because you have not only the element of surprise, but you also get a draft off the person in front.
These riders walk the line of not starting their sprint too early and thusly fading at the end...and allowing the other rider to get the jump on them and losing the advantage of getting in their draft.

SuperCluster Best Practices : Deploying Oracle 11g Database in Zones
By Giri Mandalika-Oracle on Mar 05, 2013
To be clear, this post is about a white paper that's been out there for more than two months. Access it through the following url.
Best Practices for Deploying Oracle Solaris Zones with Oracle Database 11g on SPARC SuperCluster
The focus of the paper is on databases and zones. On SuperCluster, customers have the choice of running their databases in logical domains that are dedicated to running Oracle Database 11g R2. With exclusive access to Exadata Storage Servers, those domains are aptly called "Database" domains. If the requirement mandates, it is possible to create and use all logical domains as "database domains" or "application domains" or a mix of those. Since the focus is on databases, the paper talks only about the database domains and how zones can be created, configured and used within each database domain for fine grained control over multiple databases consolidated in a SuperCluster environment.
When multiple databases are being consolidated (including RAC databases) in database logical domains, zones are one of the options that fulfill requirements such as the fault, operation, network, security and resource isolation, multiple RAC instances in a single logical domain, separate identity and independent manageability for database instances.
The best practices cover the following topics. Some of those are applicable to standalone, non-engineered environments as well.
Solaris Zones
- CPU, memory and disk space allocation
- Zone Root on Sun ZFS Storage Appliance
- Network configuration
- Use of DISM
- Use of ZFS filesystem
- SuperCluster specific zone deployment tool, ssc_exavm
- ssctuner utility
Oracle Database
- Exadata Storage Grid (Disk Group) Configuration
- Disk Group Isolation
- Shared Storage approach
- Dedicated Storage Server approach
- Resizing Grid Disks
Oracle RAC Configuration

The project will cost $6 billion and result in a facility that produces 140,000 bpd.
Iraqi Prime Minister Noori Al-Maliki and his government have an
agreement with a South Korean consortium to build a new refinery in Karbala. Costs are
expected to be in the $6 billion range, resulting in a facility
that produces 140,000 bpd. Hyundai Engineering and Construction will be the project leader.
"We are late in the building of this refinery, which was not our desire,
but it is a consequence of the circumstances that faced the
country, like the inheritance of the previous Baath regime
policies of sabotage," Mr. Al-Maliki said at a groundbreaking
Today we are putting the corner stone to build the
refinery which is considered as the newest and most developed
in Iraq and has a production power that can meet the needs of
the governorate and the other Middle Euphrates areas,
said Iraqi Deputy Prime Minister for Energy Hussain
The facility is expected to produce a refined products slate of
gasoline, liquefied petroleum gas, gasoil, jet fuel, kerosene,
fuel gas, hard sulfur and paving asphalt.
The Karbala refinery is a centerpiece of
the Al-Maliki governments stated goal to convert Iraq
from a country that imports most of its oil products to a
country that supplies its domestic market and still has
quantities allowing it to become a net exporter.

Engineers and designers are highly skilled individuals. Forcing them to enter design changes using tables, forms and spreadsheets is unproductive and uneconomical, and it increases the likelihood of human error—this is the way that most instrumentation software systems currently work. For too long, software vendors have denied engineers and designers the simple practicality of a graphical visual engineering interface with "drag and drop" capability and inbuilt intelligence, ensuring changes are automatically replicated into all the associated data and databases.

Fix an integer $d \ge 2$ and let $M_d$ be the space of real $d \times d$ matrices. Let $E$ be a vector subspace of $M_d$. We say that $E$ is transitive if $E \cdot \mathbb{R}^d_* = \mathbb{R}^d$, that is, for all vectors $v \in \mathbb{R}^d_* = \mathbb{R}^d-\{0\}$ and $w \in \mathbb{R}^d$ there exists a matrix $A \in E$ such that $A \cdot v = w$.
The question is how to determine algebraically if a space of matrices is transitive or not.
More precisely, which algebraic (ie, polynomial) conditions on the entries of matrices $A_1,...,A_k$ express the fact that the space $E$ spanned by them is non-transitive?
1) Fix the number $k$ of generators of $E$. Let $Z$ be the subset of $\mathbb{R}^{kd^2}$ corresponding to the $k$-tuples of matrices that generate a non-transitive set. That $Z$ is the projection of an algebraic set, and therefore by Tarski-Seidenberg theorem, is a semi-algebraic set.
2) Consider the analogous problem with complex matrices and vectors in $\mathbb{C}^d$, and let $Z_C$ be the set corresponding to $Z$ above. Then $Z$ is algebraic (projectivize everything and apply the theorem that says that pprojection of algebraic is algebraic). Anyway what I'd like to see are the explicit equations for this algebraic set.

What is OpenGL?
OpenGL is a set of standard API's for developing 2D and 3D graphics applications. The standard provides it in the form of a library which can be linked along wih your program (could be C/C++). OpenGL includes vast scope of API's which can be used to render figures, textures, shading, etc. The man pages are available along with openGL SDK documentation.
Getting Started With OpenGL
As such, there is lot more to discuss when we talk about OpenGL, but to start with a simple program would be a good breather for a novice. Here we'll be writing a program to draw a rectangle to get a hold of basic know-how of OpenGL programming.
The article assumes :
- Platform as Linux
- Native programming language as C
Glut libraries i.e. the openGL Utility toolkit needs to be installed which provides a platform independent windowing along with the window event handling for interactive graphics programs.
Use following commands to install openGL and Glut
sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev sudo apt-get install freeglut3
OpenGL Programming
As unusual, OpenGL programming with C also has main() as the starting point. There would be glut calls to initialise/create windows for the openGL to draw onto followed by GL calls to do the actual drawing.
First of all, call
glutInit(&argc, argv)
Next call is,
glutInitWindowSize(window-width, window-height); glutInitWindowPosition(x-coord, y-coord);
Then we need to call
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE)
Please refer the man page for more modes accepted.
Creating a window,
glutCreateWindow("Basic OpenGL Example")
Next is,
Global idle callback function is called during no event-handling. All rendering is done during the idle callbacks as to not to affect the responsiveness of the interactive events.
The next call is an openGL call,
glViewport( 0, 0, window-width, window-height )
We have to set the current matrix mode by
glMatrixMode( GL_PROJECTION )
- GL_PROJECTION - for camera positioning
- GL_MODELVIEW - for various transformations
- GL_TEXTURE - as the name suggests it is used for texturing
We can enable the depth testing, which is a part of graphics pipeline, by following call
glEnable( GL_DEPTH_TEST )
gluPerspective( 45, (float)window-width/window-height, .1, 100 )
The frustum consists of a clipping plane nearest to camera eye (called the near clipping plane) and a farthest plane from the camera eye (called far clipping plane).
Please note, any object before to the near clipping plane and farther to the far clipping plane would be clipped.
Here in our call,
- The First parameter is the angle of the camera view frustum = 45 degrees
- The second parameter is the aspect ratio = our window aspect ratio in our case
- The third parameter is the distance of the camera eye from the near clipping plane = 0.1 units
- Fourth parameter is the distance of the camera eye from the far clipping plane = 100 units
glMatrixMode( GL_MODELVIEW )
Coming to the drawing part, lets enter the drawRect() method.
The first call would be,
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)
It is a good programming practice to clear all enabled buffers before starting to draw or in between frames of animation.
Alongwith, we need to load an identity matrix before transformations which are relative to the current loaded matrix. Hence, if we want the translation/rotation to happen with respect to origin, then we need to load the identity matrix first.
glTranslatef(0,5, -20)
The actual drawing is done as:
glBegin(GL_QUADS); glColor3ub(255, 0, 0); glVertex2f(0, 3); glVertex2f(6, 3); glColor3ub(255, 255, 0); glVertex2f(6, 0); glVertex2f(0, 0); glEnd()
Here we are specifying 2D vertices in float values to draw a two colored rectangle.
Color is set through glColor(), and every vertex is drawn with the previous set glColor() call. The color is mentioned in RGB format i.e. Red, Green, Blue.
We need to explicitly call,
Thats it, we are done with openGL programming to draw a colored rectangle
The complete Program
Here is how the complete programs looks like:
FileName : myRect.c
#include<stdio.h> #include<GL/glut.h> void drawRect(); int main (int argc, char**argv) { int windowWidth = 640; int windowHeight = 480; glutInit(&argc, argv); glutInitWindowSize(windowWidth, windowHeight); glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE); glutCreateWindow("Basic OpenGL Example"); glutIdleFunc(drawRect); glViewport( 0, 0, windowWidth, windowHeight ); glMatrixMode( GL_PROJECTION ); glEnable( GL_DEPTH_TEST ); gluPerspective( 45, (float)windowWidth/windowHeight, .1, 100 ); glMatrixMode( GL_MODELVIEW ); glutMainLoop(); return 0; } void drawRect() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); glTranslatef(0,5, -20); glBegin(GL_QUADS); glColor3ub(255, 0, 0); glVertex2f(0, 3); glVertex2f(6, 3); glColor3ub(255, 255, 0); glVertex2f(6, 0); glVertex2f(0, 0); glEnd(); glutSwapBuffers(); }
Compiling and Running
While compiling, you will need to link to the installed GL and glut libraries.
gcc -Wall myRect.c -o myRect -lglut -lGLU
Now we know how to write a basic drawing program using openGL and most importantly we understand what each line of code means. Since, openGL programming needs the knowldge of its API's, hence the more you know and understand and with the ability to imagine, the more you enhance on your graphics programming skills.
For drawing animations, we can add a varying static parameter , whose value changes after every run. Hence, that would lead to a different frame each time, creating an animation. As an example, in the above program, provide the z-value of gltranslate() call as a static variable in our method drawRect(), whose value is incremented in each run. Wondering, what the animation will look like? Try and enjoy playing

Vampire Lenses and Eye Makeup for Halloween
October 19, 2013 Leave a comment
Being a vampire for a night is a lot of fun for Halloween. Along with the right costume and the right makeup, special vampire lenses are essential to pull off the scare. These colored contacts give your Halloween look the perfect finishing touch for a night of spooky fun.
You do need to decide what kind of vampire you want to be before choosing contacts. Vampire lenses come in a whole range of effects. The movie vampire look is easy to replicate with Twilight or New Moon-inspired contacts along with a costume from the movie.
For Halloween night, start with the costume and then move to colored contacts and finally the makeup. Putting on the contacts before the makeup prevents transferring oily or powdery residue on your lenses. If you wear glasses, make sure to get corrective contacts for the night. For first-time lens usage, read some basic lens care and precautions before putting them on. Some simple rules to follow are: wash your hands with mild soap before handling the lenses. Use lens solution to rinse and store the contacts. Gently slide the lens from the case onto your palm for putting it on. It's a good idea to put on your costume, contacts and makeup before the Halloween party. This way you can improve on your look and you can gauge your comfort level with the whole costume.
Besides the retro horror movie look, you can also go for a more radical 'otherworldly' feel. Vampire lenses in red or scary effects like jagged teeth are perfect. Another idea is sclera lenses that cover the entire eye to give you intense bottomless eyes. You can use eye makeup to draw creepy facial tattoos to match the frightening eyes. Use gel or liquid makeup as loose powder can fall on your contacts causing eye irritation. It's important to try on your vampire look before the big day so get your contacts well in advance before Halloween.
Remember, you'll need a prescription from your eye doctor before buying any contact lens. So, update your prescription and go for it. Be that spook that took the Vampire look all the way.
Visiondirect.com has an incredible collection of lens for Halloween, parties or theatrical productions. They'll even help you schedule an eye exam and offer discounts and rebate on various lenses. To check out it, visit: Visiondirect.com

Followed the recipe exactly except added a half a cup of Bush's black beans with the full can of Pinto Beans. OMG ! Better double the recipe because after your family tastes this there will not be enough. 5 stars !
Beef & Bean Chile Verde
From EatingWell: January/February 2008
Chile Verde, usually a slow-cooked stew of pork, jalapeños and tomatillos, becomes an easy weeknight meal with quick-cooking ground beef and store-bought green salsa. Make it a Meal: Serve with fresh cilantro, red onion and Monterey Jack. Add your favorite hot sauce.
97 Reviews for Beef & Bean Chile Verde
My husband and I love this recipe, we top it with a little reduced fat Mexican cheese and avocado, and add ghost pepper salsa for extra heat. It's so fast and easy, is perfect for a weeknight dinner, and is tasty left over as well.
I loved the sweet and spiciness the green salsa gave this dish. We added some of the Trader Joe's tomato-less corn salsa for a little extra texture and flavor. AMAZING!! I will be making this again and again.
This is a great recipe. It's so easy to change and make it your own. For example, I changed the amount of garlic to 3 cloves. I made it ahead of time and the flavors melded together beautifully. Did not have to spend time cooking when my guests arrived. Used Pace medium Salsa which is a perfect replacement for canned tomatoes that have a lot of sugar. Great for diabetics.
This was amazing! I've always used my mom's recipe but wanted to find one a bit thinner and with more diversity in flavor. This chili was perfect! I did make a few changes: ground turkey instead of beef, added salt & pepper (to taste) and added about 2 tbsp of Ketchup to add some sweetness. Perfect!

Growing up I never thought I would call Iowa my home, but I couldn't be happier. I don't think I have ever worked with a patient population or hospital staff that are as friendly and welcoming than here at the University of Iowa. Our research experience is also second to none with 2 years of devoted research time, and active faculty involvement. For those devoted to academic neurosurgery few programs in the country prepare you as well as the University of Iowa.
Neurosurgery residency at the University of Iowa is challenging, but you will get no better training at any other program. The volume of cases and their variety is second to none. I am certain that by the time I graduate, I will be competent to operate independently and have the confidence to begin my practice. Combine that with world-class research training and you have a remarkable neurosurgery experience waiting for those fortunate to seek us out.
The program offers an ideal combination of an excellent operative experience with protected time for independent research. Clinical autonomy by residents is heavily emphasized. Faculty support for your clinical and research interests is outstanding.
I love the warm, friendly, and cooperative atmosphere of the team, dedicated to serving people in need of help. It is a great privilege for me to be able to work and be trained with the other highly motivated residents who not only strive for clinical excellence but share strong interests in quality research and pursuit of a career in academic neurosurgery.

Similar to how Apple and Microsoft require you to buy a developer 'subscription' for $99. The google play costs $25, does Ubuntu have a similar cost or is it free?
The important part of the answer can be found here:
For commercial software you have to register, but:
"The Ubuntu Application Developer programme is free of charge, there are no fees to join."
Of course if you want to sell your Apps, there will be a percentage of charge:
"The application publisher chooses a global price to sell their application for. For each sale Canonical retains a transaction fee of 20% after tax. If you sell an application for 10.00 USD, then the fee will be 2.00 USD."
You can use the Ubuntu one but it goes through a review process https://wiki.ubuntu.com/AppReviewBoard/Submissions
Or you can use Launchpad and you run your own repository that other users must add to the Ubuntu software center

text: Guess what guys? We are almost through the middle of February which means March will be here soon. With March comes the reality of spring, and then summer. In light of the better days ahead, I will be showing you "how to draw a beach for kids", step by step. What better way to prepare for summer than to make a drawing of a beach. The water is a crisp blue and the sand is soft. The palm tree hangs or bows down low ready for someone to sit up and relax in it as the warm beach breeze hits their skin. I also drew in a towel and beach umbrella so we don't forget to lay under the shade for when we get too hot. This was a really fun landscape to create and like always, be sure to add your own personal touches to be more creative. That is all I have for you right now, but maybe later I will have some more drawing fun for you all. Peace people and enjoy drawing a beach for kids.

The Biopsy
For information about this topic, please click here
Clinical Oncology Service
Veterinary Hospital of the University of Pennsylvania (VHUP)
Last Modified: November 1, 2001
The biopsy specimen may be a representative piece of an abnormal tissue (incisional biopsy) or may be a large piece of tissue including the entire diseased area (excisional biopsy). It is the judgement of the clinician whether the biopsy specimen should be excisional or incisional.
Once the tissue is removed it is immersed in a 10% formalin solution for fixation. Fixation is a method of preserving the material and prevents decomposition. Once the tissue is received by a pathology laboratory, representative samples are processed, the microscopic slides prepared, and the slides evaluated by the pathologist. The pathologist will then provide a final report to the referring clinician.
In most cases a report will be available in three working days. However, in some instances this may take longer. These include:
- Bone biopsies which need to be softened prior to processing.
- Special staining techniques that may be required to identify cells, cell products, bacteria,fungi, etc.
- Difficult or unusual cases for which the pathologist will seek a consultation with other pathologists.

I live in Arizona, and I can never tell if I am watering my plants too little or too much. Plants are very touchy here - and you have to be able to read the signs correctly. I can't.
What signs are there for each?
There are various ceramic tools you can use, but I've never tried them.
There are signs, tomatoes for instance, will have more fuzz on the sides to collect any water available
But most gardening books just say stick your thumb into the dirt, if it feels dry then it is time to water, don't wait till the plant turns brown.
That being said, make sure you don't water too much and have some system of making sure your water gets down to the roots (a little berm perhaps). That'll prevent your plant from keeping its roots up near the top of the soil where it dries out quicker.
I have a moisture meter with a 6" or so long probe. It's great for checking soil moisture below the surface, and it's not very expensive. I'm afraid to stick my finger in deeply and disturb the roots for some plants. Also, I've seen the top inch of soil be dusty dry, but there's a surprising amount of moisture 3-4" down.
Once you get in the habit of using it, you'll get a better feel for how much moisture is really in the soil.
This is much easier and more reliable than looking for signs of stress in your plants. And if your plants are showing signs of stress, they're already damaged -- better to avoid that in the first place.
If you say your plant is very sensitive to over-watering, I assume it is a kind of plant that doesn't like a lot of water. The key is to know how much water your plant needs. Try googling for more info regarding your plant. The season also matters; in the summer you should water your plants more often, while in the winter you should reduce your watering.
My advice is to stick your fingers into the soil. If it is completely dry, you may want to water it. However, if the weather is not hot and the plant hates water, you can wait and see for a couple of days. Otherwise, you can water it when the soil is dry.
When you water the plant, you have to pour the water gently and keep watering until the water comes out of the pot. This makes sure the water gets to the root and not just the top layer of soil.

Dumb guns
On our website now, E. J. Dionne Jr. on Georgia's new "guns everywhere" legislation that expressly allows people to bring their weapons to church, among other places:
Nothing better reveals the utter irrationality of our politics for the whole world to see than this madness about guns -- and no issue better demonstrates how deeply divided our nation is by region, ideology, and party…. Nowhere else in the world do the laws on firearms become the playthings of politicians and lobbyists intent on manufacturing cultural conflict. Nowhere else do elected officials turn the matter of taking a gun to church into a searing ideological question. But then, guns are not a religion in most countries.
Dionne's latest comes on the heels of the National Rifle Association's "Stand and Fight" rally, held in Indianapolis over the weekend, where Sarah Palin with Christian motherly charm declared that "waterboarding is how we baptize terrorists." And she demonstrated glancing acquaintance with transitive logic in getting to the red-meat portion of her remarks: "If you control oil, you control an economy. If you control money, you control commerce. But if you control arms, you control the people, and that is what they're trying to do." [Applause]
They, being the Obama administration, which at last check had taken action on gun reform off the legislative docket. But faith of course is famously resistant to fact and reason.
Carrying a concealed weapon is legal in all fifty states, and if anything, a universal gun law—reciprocity among states—is much closer to reality than further restrictions at either the national or state levels (where, as Dionne and others note, more than seventy laws loosening restrictions on guns were enacted in the year following the Sandy Hook massacre). Reciprocity has the backing of Republicans in the U.S. Senate, which according to some polling could tilt their way this fall. And it has behind it the treasure and talent for propaganda of the NRA and other gun groups, which are casting it as a way to fight back against crime, although the national rate of violent crime declined steadily from 1993 to 2001 and again from 2008 through 2013.
Casting itself as a counterbalance to the gun lobby is Every Town for Gun Safety, which funded with $50 million from former New York mayor Michael Bloomberg is pushing for stricter, more uniform background checks and a review of the role weapons play in domestic violence and suicide. Those are pretty innocuous and eminently reasonable aims, but reason doesn't wash with zero-summers like Larry Pratt, executive director of Gun Owners of America. You can hear him on this recent NPR OnPoint segment (starting at about the 15:10 mark), but these excerpts are representative: "[M]ass killings are an abstract notion and don't particularly upset the gun owners who can protect themselves." "The whole effort of gun control is transparent: they ['the elite types,' as Pratt calls them] are coming for the guns." "Background checks don't work…. The only thing a background check does is allow the government to compile a list of names… we don't want that information getting in the hands of a government that's out of control."
Efforts to manufacture and market smart guns are being met with a similarly unhinged response; today's New York Times has a story on Belinda Padilla, whose firm Armatix is trying to sell "a new .22-caliber handgun that uses a radio frequency-enabled stopwatch to identify the authorized user so no one else can fire it." Padilla has received threatening phone calls for daring to help this new company get off the ground, while photos of where she keeps a post office box have been posted online. When the reasonable and supportive president of a local gun club said the Armatix weapon "could revolutionize the gun industry," gun activists went into overdrive:
They took to Calguns.net, a forum for gun owners, and called for vigilante-style investigations of Ms. Padilla and Armatix. They seized on her appearance before a United Nations panel to testify on gun safety and her purported association with a group once led by a protégé of George Soros.
"I have no qualms with the idea of personally and professionally leveling the life of someone who has attempted to profit from disarming me and my fellow Americans," one commenter wrote.
Dionne begins his column by asking: "Have we gone stark raving mad?" Some obviously have. Others, like the reasonable people in groups like Every Town for Gun Safety, show signs of sanity.

There is something pretty intimidating about arguing with gun nuts.
They usually descend like harpies on articles like these. I'm waiting.
stricter, more uniform background checks and a review of the role weapons play in domestic violence and suicide. Those are pretty innocuous and eminently reasonable aims
Sure. But innocuous and reasonable doesn't seem to drive contemporary politics.
Laws like the Georgia law infuriate me. Can we have our spaces free of instruments of death?
Jim Pauwels - The problem is that the ones who can least handle the power of life and death are the ones who most desperately want it.
Here you go - it really doesn't make any sense:
"Carrying a concealed weapon is legal in all fifty states"
I'm in favor of reasonable weapons regulattion, but this is simply not true. Reciprocity, whatever that means, does not exist.
There should be restrictions on the number of weapons possessed by a single individual and th number of rounds that can be loaaded ina single weapon at one time. There are a number of other reasonable measurs that can be undertaken.
Joe - reciprocity does not exist (yet), that is true; what is true is that carrying a concealed weapon is legal in all fifty states. Rules on where one can carry a weapon vary by state; in Illinois, for instance, you can take it into church but not into a park; in Georgia, you can take it into church and a park, which this guy did in Forsyth County last Thursday, "stalking the park," as it was described, much to the discomfort of parents and children attending a Little League game. More than twenty calls were made to 911, but sheriffs said they couldn't do anything because the man with the gun was acting within his rights.
I grew up around hunting rifles and a small town where hunting was part of the culture but I really don't see how anything good can happen from the proliferation of handguns in the US. And concealed carry permits?! What could possibly go wrong
And there is this from Fr. Z (this is completely off the charts even for him which is saying something!)
About carrying a handgun while saying Mass… I am neutral on that point.
He is neutral about carrying a handgun while saying mass!
Finally, maybe it would be a good idea for all priest and bishops to obtain concealed carry weapon licenses.
So there you have it. Fr. Z is packing heat! Scary thought!
Scary indeed. Now turn to your neighbor, complement him on his Glock .40 and nice shoulder holster, and say, "Peace be with you."
Concealed carry is not legal in NYC, where I live, unless you have a permit. The average law abiding citizen cannot get a permit. So to say it is legal everywhere is misleading. In Georgia you may NOT take the gun into church if the church does not permit it. reasonable minds can differ about the nature of restrictions on guns. Why people in NYC should be upset about what they do in Ga. is not clear to me. On the other hand Ga. style permissiveness would not fly in a city of 8 million people where noon time crowds can literally force you off the sidewalk, and milions of transients pass through daily. Hysterical tirades like Dionne's persuade nobody. People who disagree with you will listen to reason if addressed in a reasonable tone. If you address the with the complete contempt that Mr. donne does you won't get anywhere.
How does this grab you: "About carrying a handgun while saying Mass… I am neutral on that point."
Who else but the inimitable Fr. Z would think such a thing. Sigh.
QUAERITUR: Are priests allowed to carry handguns? | Fr. Z's Blog
I know Ann and couple that with a siege mentality when it comes the the Church, a general feeling that we are in an inter-ecclesial "war", an agressive temperment (at least as reflected in online comments), and questions can and should be asked by relevant authorities why he feels the need to have weapons. As someone in a position of leadership (at least somewhat I don't think he has a parish or ministers to actual, real people but still..), his comments are irresponsible and should be reported at least to the bishop.
As I said, I grew up around hunting rifles and this was in the day when they were propped up in the closet, in their case, with the shells right on the top shelf (even before the subsequent laws around proper at home storage, etc) so am not hyper-allergic to weapons.
But, I would certainly not feel safe in a church of all places with a priest without training or experience having a handgun. It just creates a general aura of fear that is not psychologically healthy and disproportionate to any actual threat he might experience.
Seriously.....very concerning....
Is this really something you worry about? Do you really think anyone is going to be shot in Church by a second amendment activist? Do you live in Georgia? Is it legal to carry a gun into Church where you live? You are aware that even in Georgia if the pastor says no guns then they are not permitted. I cannot think of any priest I have ever met that would carry a gun in Church. The idea is ludicrous. It's the hysterical tone of articles like this that are aimed at creating the "general aura of fear . . disproportionate to any actual threat" that you bemoan.
Is this really something you worry about?
Yes it is. I live in Canada and have seen unbalanced people use firerams to threaten their family. Not a lot but enough to make me concerned about ensuring that weapons are used responsibly by responsible people. And proliferation of these weapons simply cannot be good for public safety.
Do you really think anyone is going to be shot in Church by a second amendment activist?
Is it legal to carry a gun into Church where you live?
I cannot think of any priest I have ever met that would carry a gun in Church.
Fr. Zuhlsdorf is a likely candidate and has written about in his blog. And apparently, according to him, he has quite the following and is influential in some Catholic circles.
The idea is ludicrous.
Not according to Fr. Z.

How can I measure the mass of the Earth at home?
How was the mass of the Earth first measured?
Yes we/you can.
I recall seeing a famous video of a homemade version of the Cavendish torsion balance experiment from the early 1960's, made I think for the PSSC high school course. Basically, the physicist hung a torsion balance from a high ceiling by a long (>10 m?) piece of computer data tape (chosen because it would not stretch). He carefully minimized air currents. The torsion masses were two .5 kg bottles of water on a wooden bar (no magnetic interference). Mass, in the form of boxes of sand, say 20kg was piled around on the floor as static mass and then reversed in position with respect to the suspended masses. There was a clear plastic box around the balance (with a hole in its top for the suspending tape to pass through) also to minimize the effect of air currents, since the lateral force on each bottle is about G*m1*m2/r^2 = (6.7e-11)*0.5kg*20kg/(0.1m)^2 N ~ 6.7e-8 N, i.e. a lateral force on each bottle equivalent to that generated by a weight of about 7 micrograms, about that of a 1 mm^3 grain of sand. This is visible to us because the long arms of the torsion balance convert this small force into a torque on the suspending filament, and the restoring torque is itself very small.
I found an Italian dubbed version of the video on Youtube. See http://www.youtube.com/watch?v=uUGpF3h3RaM&feature=related and a slightly longer version at http://www.youtube.com/watch?v=V4hWMLjfe_M&feature=related. I believe the demonstrator was Prof. Jerrold Zacharias from MIT and the PSSC staff. If anyone can point me to the original undubbed black and white film loop, I'd appreciate it.
It looked really crude but qualitatively it worked. The mirror moved upon reversal of the mass positions. Yeah, experimental physics!! Calculate it out. Use your laser pointer. Glue mirrors. Calibrate. Give it as an experiment in class. Make a (music?) video. Put it on Youtube and embed it here. Social physics.
I also found some other do it your self experimenters with crude equipment, experimental tips (try fishing line) and different masses. See http://funcall.blogspot.com/2009/04/lets-do-twist.html http://www.hep.fsu.edu/~wahl/phy3802/expinfo/cavendish/cenco_grav.pdf and http://www.fourmilab.ch/gravitation/foobar/, which uses a ladder, some cobblestones, monofilament fishing line and has videos. For the experiment in this last reference, you don't need mirrors, since you can see the balance masses move directly because their excursion is so large. See also http://www.youtube.com/watch?v=euvWU-4_B5Y
For all these experiments there is no calibration of the restoring force of the twisted filament (which Cavendish did from the free torsion period of the balance), the balance beam of one appears to be styrofoam, (so I would worry about subtle charge effects), and the beam hits the support of the fixed masses so that it bounces and we do not see the harmonic angular acceleration we might expect. This last problem is apparently well known to amateur experimenters in this field. Another exposition and video is at http://www.juliantrubin.com/bigten/cavendishg.html
The best summary and historical exposition I found is at https://en.wikipedia.org/wiki/Torsion_bar_experiment . I did not realize that the experiment was originally designed by John Michell, a contemporary, whose designs and apparatus passed to Cavendish upon his death. See https://en.wikipedia.org/wiki/John_Michell. Newton had considered the deviation from vertical that a stationary pendulum would have near a terrestrial mountain in the Principia (1686). Although he considered the deviation too small to measure, it was measured 52 years later at Chimborazo, Ecuador in 1738, which was the first experiment showing that the Earth was not hollow, apparently a live hypothesis at the time. The same experiment was repeated in Scotland in 1774. See https://en.wikipedia.org/wiki/Schiehallion_experiment . Mitchell devised the torsion balance experiment in 1783, and started construction of a torsion balance. Cavendish did his experiment in 1797-1798. To me this is all quite inspiring.
Editorial (I'll move this positive rant to meta soon) - given the obviously widely varied audience on this site, I would very much like to see more questions like this one relating to amateur or home experiments. The analysis of the data and possible sources of errors in these experiments is often subtle, and is very instructive. To have real physicists and other clever students publicly criticize some aspect of an experiment provides something that many students may never get otherwise. The social network framework will help many newcomers from different countries learn what real science is in a way that yet another dose of imperfectly understood theory never will. And it's fun too.
You can make estimates of the earth's mass $M_e$ by estimating it's average density $\rho$ and using the formula $M_e = \rho \cdot V$, where of course $V= \frac{4}{3} \pi R^3$, so you have to know the earth's radius $R$. This method is rather a gamble because you don't know the earth's average density (suppose the earth would be hollow?). Newton made such an estimate himself.
Newton's law of gravitation $F_{grav} = G \cdot \frac{M_e \cdot m}{R^2} = m \cdot g$ describes the attraction between a mass $m$ on the earth's surface and the earth. While $m$, $g$, so $F_{grav}$ and $R$ can be determined, there are two unknowns: $M_e$ and $G$.
So one can only determine the mass of the earth together with this constant $G$: the gravitational constant.
You cannot measure the mass of the earth at home, unless you have access to a Cavendish torsion balance to measure the gravitational constant. The Cavendish experiment is described in this Wikipedia article. Approx. 100 years after Newton the first experiment was done to measure $G$.
The value of $G \cdot M_e$ can be measured very accurately (3,9860042·1014 m³/s²).
The earth's mass is not constant, it is estimated that every day 40 tons of dust from meteorites hit it. This is totally neglectible for a mass of 5,9736 ∙ 10^24 kg.
You can't measure the mass of Earth directly, as others have stated. You can calculate it knowing:
and solving the following equation:
$mg = \frac{GM_em}{R_e^2}$ or $M_e = \frac{g R_e^2}{G}$
As Gerard stated you can't directly measure the mass of the Earth.
You can measure the acceleration of gravity at the Earth's surface using a simple pendulum. You need to know two things: The length of the pendulum, which can be accurately and easily measured with a ruler. The period of the oscillation, which can be measured by taking a stop-watch and timing a number of small swings.
Then use the formula:
$g = \frac{4 \pi ^2 L}{T^2}$
Where L is the length and T is the period.
This is then related to the mass by:
$M = \frac{g R^2}{G}$
Where R is the radius of the earth and G is Newtons gravitational constant.
You still need to know these other quantities, as Gerard said. I don't know how you would find R or G at home.
