I'm using this mouse right now. It's simple, but it's pretty comfortable for me to use. One minor (for me) drawback is that there's no thumb button for the browser "back" function. I've had it for 6 months or so of daily use at work for 8+ hours a day and have yet to change the battery. It's hard to go wrong with a wireless mouse for $7!
One other thing I just thought of. I wouldn't recommend this for a travel mouse since there's no place to store the receiver in the mouse, so it would be likely to get lost.
I just looked at it again and couldn't resist at that price. I just bought a mouse that I don't even need. THANKS A LOT WOOT! LOOK WHAT YOU MADE ME DO!
Thanks for the heads up about not having storage for the USB dongle. I have an M215 and it does have a storage spot and assumed the M315 would as well. I guess I will make the M215 my travel mouse and use the M315 for everyday use.
@spauldingd: I think the 305 (I have) is the last model where you can store the receiver in the mouse. After that, I think their idea was to just stick the mouse into the laptop and leave it there which makes sense.
@spauldingd: I didn't realize anyone was actually going to read what I wrote. That's a lot of pressure to provide accurate information. Now I know how all those journalists who cover breaking news feel :-)
In that spirit, I have a correction. The M315 DOES have a place to store the receiver, however you have to remove the battery cover to get to it. As mentioned, I've never changed the battery, so I never noticed it before. Also, I use it for my work laptop and leave it on my desk (travel mouse stays in by laptop bag), so I never needed to store the receiver.
I just learned something about my stuff because of you!
Anyone else amazed at just how cheap these are now? I thought $9.99 last year was low, and that was with a 2 inch long reciever! Sorry, old feeling moment.
As a seller of these types of Logitech mice (mouses?), Logitech does indeed have a travel compartment inside the mouse next to the battery slot for the receiver for storage for most mice models from the M185 and up. This does include the M215, 305, 310, 315, 325, 505, 510, 515, 525, and 705. As to why Logitech felt the need to make so many models so similar to each other is another issue. It is almost unnecessary to remove the receiver since the receiver itself is a micro size that one can leave it in the USB slot when transporting your laptop around.
@egagroupusa: Agree, I'm looking at my m315 mouse right now and there's a little slot in the battery bay where the universal receiver is supposed to be stored. Maybe previous models didn't have the compartment?
@egagroupusa: Meeses I believe is the term.
@meanolthing: you are correct, previous models did not have the compartment for storage. Take a look at the V200/V220 models where there is a clunky bar-like receiver that stuck out and many people have broken them by kicking or knocking into it while it is plugged into the front of their computer. The new technology is the unifying receiver that allows you to sync up to 6 devices with one receiver so you can free up your precious USB slots. Its a neat feature to mix and match your style of Mouse and Keyboard and even headset to one receiver.
I was in a store yesterday and saw this exact mouse for this price. I want to say it was Target but don't hold me to that. I really should pick one up for this price as my son has chewed the mouse wheel of my old logitech I used for my laptop. It still scrolls but hangs up sometimes. This seems pretty similar to that one so for the price I might as well replace it. Stores should market to kids directly. "Go eat daddies electronics because its fun." And then he can come buy replacements from us. :)
Knowing that this DOES have USB dongle storage inside the battery compartment is good news. On another subject, because this mouse only uses 1 battery, I like to use up all my "used" AA batteries in the mouse. I usually get several weeks or months from batteries that stopped working in whatever device they were in. I mostly use rechargeables, but for the alkalines that I do require, this lets me squeeze that last bit of life out of them.
This seems to be dead, when I get to the Best Buy site , I cannot add this to the cart.
@bradawn: I just did it now - 9:19AM Pacific.
Now it is showing me add to cart, I have 3 of these from earlier deals. I like them alot.
Great mouse, in for one. Actually using one right now as is my lady sitting next to me. Both have lasted quite some time and see them lasting for a while longer.
Just ordered one at 2:55PM PST
Awesome deal. Too bad I brought it for 10 bucks on BF.
Can you click the mouse wheel laterally to scroll sideways like you can on some of the other models? I ask because the other models have the left/right arrows at the wheel and I don't see any on this model.
I really really want one, just because it's a good deal. But I don't need one, my M305 is still just fine.
Target had these for $7 too. Just bought two of them - the only two without scribble art designs on them.
Too bad - sold out! :(
Deal dead. $29.99 now.

If you are logged in to your Blogger account, you can easily download a dump of your website by clicking on the Settings → Other → Export Blog link. (Source.)
How can I do this automatically each day on Linux, from a cron job?
First you need to do a login with curl and then you can simply invoke another call to the download link.
I would follow this article to accomplish this. The trick is to find out which URL you need to call to export your blog.
What I did is:
You will see the download happening, and you will see a new record in the network tab. Mine is : http://draft.blogger.com/feeds/7135654868651822450/archive (if not authenticated you will get 404).
(update by Mark Harrison) Based on the information above, here is a script that will download the xml dump of the blog. (end update)
As someone who uses Backupify, IFTTT, Zapier and a handful of other cloud connecting sites, I think in your case, a one time dump plus a IFTTT -> Dropbox for posts and files would be your best bet. To verify it's working, you could also have it send you an email with your post.
IFTTT has been around for years now and has always been reliable. They are planning on charging at some point, but I can't imagine you would fall under that for just this use case alone.
Backupify will charge you right off the bat.

Let $V_n$ be the standard permutation representation of the symmetric group $S_n$, and let $\mathbb{S}_{\lambda}$ denote the Schur functor associated to the partition $\lambda$.
Let $\lambda$ range over all partitions of some natural number $k$. We may ask for the smallest $n$ making the characters of the representations $\mathbb{S}_{\lambda} V_n$ linearly independent. A little experimentation indicates that $n=k$.
If instead $\lambda$ ranges over all partitions of natural numbers less than or equal to $k$, it seems that $n=2k$.
Are these patterns correct?

This article was originally published before Instagram responded to the outrage with this message. Instagram has removed the confusing clause and apologized for the misunderstanding. Therefore some of the content of this post is no longer timely, but I believe the over-arching point about what people will accept from a social network is still worth discussing.
Thank goodness there's somebody out there pawing through massive license agreements and thank goodness the Internet allows for people to share the important parts.
Instagram just made everybody very, very unhappy by tweaking their terms of service. Here's the changes Instagram highlighted, in my words, not theirs:
- You still own your photos.
- Instagram now syncs more effectively with Facebook.
- The new rules help protect you.
You don't need me to say that these three bullet points are meaninglessly vague. Here's the actual meat of the changes, buried in the fine print. This is the stuff that's got everyone up-in-arms (this time in their words, my highlights):
Some or all of the Service may be supported by advertising revenue. To help us deliver interesting paid or sponsored content or promotions, you agree that a business or other entity may pay us to display your username, likeness, photos (along with any associated metadata), and/or actions you take, in connection with paid or sponsored content or promotions, without any compensation to you.
"Attention amateur and professional photographers. In order to make your service more awesome, we can sell your work and information to other companies without telling you or paying you."
The new terms do some weird mental gymnastics with wordplay and logic. Instagram claims no ownership of any of the content you post. But they also reserve the right to sell it. I'm pretty sure there's a word for selling something you don't own. One of those words etched into a stone tablet after "Thou shall not…"
Alright, alright, I'm need to dial it back a bit. After all, Instagram is a free service, and free services have to make money somehow, right? Advertising is the logical next step. Facebook spent $1 billion to buy Instagram earlier this year, and naturally they're going to want to make that money back sooner rather than later.
At this point, it's not like anyone should be surprised about Facebook sneakily changing privacy settings. I'm going to assume that applies to the companies they've purchased too. So why is the Instagram thing making people so mad? Why is it OK when Facebook provides your information to advertisers, but not OK when Instagram gives your photos to advertisers?
Mostly, it's because of what the two services do. Mostly, Facebook is for connecting with people. Mostly, Instagram is for creating and sharing photos. You don't make anything with Facebook. Facebook wants your information and your photos, but it never gave you a way to create something. And when Facebook shares that information, it's so advertisers have information and ways to contact people, not so the advertisers have a go-to database of creative work. Instagram tried to build a community for photographers, providing them both a way to take and way to host their images. Then after they got millions of users, they suddenly declared all the users' work to be theirs (without legally "owning" it).
Turns out, that while most people are not very protective of their personal information, they're very protective of the things they create. Instagram just found out where the line in the sand was for people sharing on social media.

What are the tools used to create the instructions and arrows in such images?
Which one is the font?
What are the tools used to create the instructions and arrows in such images?
You can use different programs to do that image. I would use Photoshop, if you have access to it, depends on your OS (mac has great easy soft for this, and Gimp is an excellent program that you can download for free).
For Photoshop, put a black layer with 70% opacity for the background, then for the arrows you could use any of these shapes: http://www.shapes4free.com/shapes-resources/850-free-photoshop-arrow-shapes/
And about the font, you could pick your own from here: http://www.dafont.com/theme.php?cat=603
In addition to this answer: arrows are not shape,(they can be used as alternative)but you can get same brush from here
Make sure all the materials you use have the appropriate licence if you want to distribute your creation.
I've long been interested in these hand drawn arrows and think I've now nailed down the process. Believe me, I've tried all sorts of long winded techniques like hand drawing the arrow, then scanning and recreating in illustrator probably not an uncommon method but not as quick as this next method.
As correctly pointed out above by utopicam, use the shape tool and find some arrows. The steps are all in this image.
If your primary purpose for asking this question is that you want to facilitate User Interface mockups and screen annotations (as illustrated) then you may be interested in Balsamiq. This is a purpose-built tool for UI wireframing and it is excellent for that purpose.

Anyone got these achievements for all difficulties? As the title says, what is the best way to defeat an AI in under five minutes?
Cannon rush works reliably against Insane AI. Works best against enemy Protoss; creep and fast zerglings makes things complicated. Blistering sands is good. If you get it for Insane, you'll simultaneously get it for lower AI levels.
You should get 'GG' at 4:30.
Yeah. I got it on insane, ZvT (i was playing zerg). An early pool and then zergling rush should do it.
When i got into the Terran base, there was an scv building a barracks. Killed that SCV, and the AI gave up. 8-D
You are going to want to 6-pool. I don't even think you need gas for this type of push, and you might not even need the Queen. Just get those lings in there base and micro a bit to take out any marines that pop out.
The A.I. will do some funky things with its drones to try to deal with the early rush, so constant ling pressure and you should be fine.
Remember insane A.I. gathers 7 minerals to your 5 minerals so it is critical you hit that supply line.

STEUBENVILLE - The Catholic Central volleyball team has not fared too well against opponents from Jefferson County so far this season.
Catholic Central entered their match with local rival Toronto Wednesday night with a record of 0-4 against county opponents, but the Crusaders were finally able to get one in the win column with a big victory over the Red Knights.
"It was a good night," Catholic Central (9-6) head coach Sherri Barber said. "We played better tonight."
Article Photos
PLAYING DEFENSE — Toronto's Chelsea Anderson pushes the ball across the net as members of the Catholic Central volleyball team play defense — Taylor Bednar (5), Logan Colabella (2), Kamy Belardine (22), Megan Lloyd (3) and Monica Fischer. The Crusaders won 25-8, 25-22, 25-12.
-- Mike Mathison
The Crusaders played a strong match from the outset en route to a 25-8, 25-23, 25-12, victory.
"We were satisfied to win some of the battles tonight, but we need to finish and win the war," Toronto head coach Chelsey Fletcher said. "It was nice. We really competed in the second set against a sound program. Catholic Central has had a sound program for many years.
"We don't want to just compete for three sets. We went to compete for all five sets. Tonight, we let our nerves get in the way of that."
Individually for Central, Robyn Runkle collected three aces, 42 sets, 21 points and one kill, Monica Fischer recorded one dig, six kills and 11 points and Madeliney Gulan ended up with one ace, four kills and four points.
Megan Lloyd tallied one ace, two blocks, 27 sets and 17 points; Monica Rigaud delivered four blocks, and seven kills; Taylor Bednar produced four kills and 10 points; Kamy Belardine contributed one dig and nine points; and Logan Colabella finished with and one kill.
"Fischer is a fantastic hitter," Fletcher said. "Their middle hitters and their outside hitters are phenomenal."
Individually for Toronto, Miranda Robinson recorded eight points, nine kills, one dig, one block and four assists; Amber Fuller tallied 10 points, two kills, one dig and four assists; and Chelsea Anderson netted eight points, two kills and one block.
Josey Jones scored nine points to go along with one kill and two digs; Katie Spadafora finished with four points, one kill and five blocks; Emily Anderson delivered four points, one kill and two digs; and Mykia West collected two kills and one dig.
"I didn't know a lot about them coming into the match," Barber said. "I have read the quotes in the paper from their coach the last few years. She has had some pretty nice quotes.
"We had a tough loss last night, and I made the kids come in at 4 p.m. today. I talked to them. I told the seniors they need to step up. I inherited a team with seven seniors on it. I told them they needed to pick it up, and they did.
"Every match, we have a word of the day, and today's word was responsibility."
Both teams are scheduled to return to the court today. The Crusaders will host Conotton Valley in their third match in three days.
Toronto will take part in a tri-match along with Paden City at Linsly.
"I told both groups (the seniors and underclassmen) that they needed to relax," Barber said. "This game is supposed to be fun. In big games, we are not having fun. We are playing tight. I told them they need to relax and enjoy it.
"The seniors stepped up tonight. What a difference that made. I have a coachable group of kids. I really do. They are very coachable.
"Volleyball is a game of momentum. Sometimes, it can be hard to get back up. You have to have that confidence. We are not done. We have six games left, and then we are going to get ready for the state tournament. We have to stay positive. We have a good team. We are not done yet. You are going to be hearing about us.
"Our bench stepped up. Fran (Capaldi) and Ashlynne Daley are juniors. They are going to be a great help to us next year."

An old adage that many programmers stick to is "It takes a certain type of mind to learn programming, and not everyone can do it."
Now I'm sure that we all have our own trove of anecdotal evidence, but has this been studied scientifically?
An old adage that many programmers stick to is "It takes a certain type of mind to learn programming, and not everyone can do it."
Now I'm sure that we all have our own trove of anecdotal evidence, but has this been studied scientifically?
We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.
Another study, Investigating the viability of mental models held by novice programmers:
Also, see later research from the same authors of the Sheep vs Goats study (which was never actually published, to be clear). Their last and most recent study on this topic from 2009 is Meta-analysis of the effect of consistency on success in early learning of programming (pdf).
Yes, there's a pretty famous paper online designed to more or less determine "Who is cut out to be a programmer."
A cognitive study of early learning of programming - Prof Richard Bornat, Dr. Ray Adams
Here's a blog post by Jeff Atwood that interprets the results and puts some things into context.
Anyone can be a programmer. Consider how easily people grasp spreadsheets. Consider how readily Alan Kay introduces children to programming by means of experiment and exploration in a programmable environment.
People may study success in college-level courses and conclude "some people aren't fit to learn programming". However, such a conclusion severely oversteps the bounds of the observed evidence. How much failure could instead be attributed to how the programming is taught (too abstract?), or which style of programming is taught (too imperative?), or the programming environment (compilation, no immediate feedback?).
It is well understood that people grasp abstractions most readily after they've already worked with multiple concrete instances - i.e. that we cannot learn something until we almost already know it. Starting with the abstract, therefore, is an entirely foolish way to teach programming. Many people who stumble over premisconceived "mental models" would thrive if taught in a more concrete environment with real-time feedback (e.g. as in the Kahn Academy for CS) then encouraged to climb the ladder of abstraction when they are ready for it. Learnable Programming is a recent essay by Bret Victor draws attention to unnecessary environmental challenges programmers face in learning.
In some cases, it is the students that fail their classes. Intellectual laziness and willful ignorance will exist in any large group of humans. Smart folk are no exception, as anyone who has argued with a brilliant crank can attest. But, especially for programming and maths, it is often the classes that are failing the students.
Maybe this is anecdotal, but when I taught intro programming to a few hundred liberal arts students, I found no such "double hump". It seemed to me they were all quite capable, though some worked harder than others, and a very few tried to bluff their way through.
A lot has to do with how it is taught.
A lot also has to do with desire - some don't find programming the least bit interesting. But even so, they can learn it if they give it an honest effort.
When I started out it was common to sit an "aptitude test" before you got a programming job. There were not so many computer science graduates, so it was common to recruit from other disciplines.
The tests were similar to what you see on IQ tests (what's the next number in the sequence, etc.).
The anecdotal evidence was that while not everyone who passed the test became a good programmer, no one who failed the test but was hired for other reasons ever became a good programmer.
Sadly HR drones did not understand these tests (and failed when they took them!), so recruitment these days depends on things HR drones understand -- good college, communication and suit wearing skills.
This is pretty much the reason large IT departments have lots of people who are great at PowerPoint shows and very few good programmers.
One can make studies about abstraction capacities, or other useful knowledge, but the definition of programming is unclear, and I think the quote is irrelevant, because there are opposite ways to look at programming:
The first kind: Programming languages are (or should be) some kind of human language made to describe a task for the computer to execute, so everyone who talks should be able to program. It's called scripting, BASIC, the typesetting system TeX, etc... The language or the system doesn't matter, it's the way their creators and people looked at it: "Dear program/computer, please print my name", rather than "Get me space the size of eleven chars, then give me the adress of this space, then let me store it, then enter eleven characters into this memory which you can take out of my keyboard buffer (but don't forget to clean it, etc."
In this case it's clear that the study would rather be "Not every language can be assimilated quickly?".
On the other hand, programming languages are just a way to describe how a computer works or how it should work, how it should be 'connected' if you think of 1950s computers. Therefore the programmer can't do anything, even if he 'speaks' the programming language perfectly, if his/her intelligence can't reach this abstraction level where you see bytes beeing stored in memory, strings as pointers, etc., and then go back to earth to link it to the problem. Therefore not every human can program (in assembly language...).
Apart from this, you will need all qualities required to work and produce something: know very well what you want, make it easy for others to understand/complete/review, focus on your objectives, etc... But just like an architect, a writer, a musician, a prostit..aehh prothesist, etc.
But most humans have good abstractions capacities, especially children. Some German schools are teaching Haskell to pre-teens (programming languages like Pascal or Delphi are beeing taught in every German school).
So I would say the question is very hard to answer, and any answer (or study) is likely to be irrelevant.
You will find a very brief analysis of how people learn programming in the article Teach Yourself Programming in Ten Years by Peter Norvig. He seems to think there is no born programmer.
To those citing Dehnadi and Bornat's double-hump or goats-vs-sheep study, it's worthwhile to check out Mental Models and Programming Aptitude by Caspersen et al (2007) in which they attempt to replicate it:
Many years ago I did several courses that included military leadership theory. Part of the theory was that there exists a leadership continuum, from those who are natural leaders to those who couldn't lead a dog on a leash. The idea was that people were distributed on this leadership continuum in a bell curve, with most people being somewhere between the two extremes. Apart from the few at the far extreme "couldn't lead a dog" end almost everyone could be taught the art of leadership. The amount of effort required to turn someone into a leader depended on where they sat on the continuum.
I suspect programming has a similar continuum and a similar distribution. There'll be those that just get it effortlessly, and those that could never get it if their lives depended on it. But they're the few at the tail of the bell curve. Most people sit between those extremes on the continuum. They can learn to program but the effort required to teach them will depend on where on the continuum they sit.
I'm not sure it's just programming. I saw the same sort of phenomenon with people simply learning to use computers. Back in college I was a lab assistant in a lab that hosted a computer literacy for seniors class.
Within two weeks I could identify those who would get it and those who wouldn't with basically 100% accuracy. You either accepted that this is the way the computer works or you beat your head against it for the whole class. There was no middle ground. (The fact that it was a seniors class meant we had a lot of head-beaters which made the pattern much more obvious.)

Tablet manufacturing problems and tablet-tooling failures are generally the result of one or a combination of the following:
The seven-step process1. Clean. When tooling is removed from the tablet press, it should be thoroughly cleaned and dried to remove any oil or product residue, especially from difficult-to-reach areas (e.g., in embossing and keyways). Equipment used for this process could include ultrasonic cleaning and automated washing processes. It is essential, however, that the process does not cause corrosion of the tooling material, and to that end, a corrosion inhibitor should be used.
2. Assess. Punches and dies should be visually inspected under magnification for signs of damage, wear, or corrosion and to validate the cleaning process. This assessment will establish if the production process is running well or not. The assessment will also give clues to problems with the tablet press or tooling itself and indicate if any tooling maintenance is required. Typical equipment includes high magnification lenses and microscopes.
3. Repair. Light surface wear, corrosion, and damage on tooling can be repaired and polished to a usable condition. Worn tips can result in poor quality tablets and inferior embossing definition, which can lead to picking and sticking. Equipment such as a motorized chuck and double-ended polishing motor are used in conjunction with polishing accessories. Repair should be carried out by well-trained and experienced maintenance technicians to ensure that the tooling is not taken out of tolerance limits. Repair should not be carried out on coated tooling as this may remove the coating from the punch.
4. Measure. Measuring is essential after repair to ensure that crucial tooling dimensions have been maintained within an acceptable working tolerance. The equipment for measuring can range from simple hand-held micrometers, vernier callipers, and height gauges to semi-automatic, computerized, digital gauging systems. Measuring should be carried out at regular intervals, even if repair has not been necessary, to check for natural wear during the compaction process. The essential measurement is the critical working length of the punch as this controls tablet thickness, weight, and dosage.
5. Polish. Controlled, light polishing on a frequent basis will ensure that the tools are maintained to a smooth finish, helping to maximize tooling life and reduce problems such as sticking and capping. Remedial, manual polishing can be conducted using double-ended polishing motors with nylon polishing wheels and fine abrasive compounds. A more controlled and consistent process is the automated, drag polishing system, which relies less on the skill and experience of the operator. This also allows for up to 70 punches to be polished in one 20-minute cycle, thus providing efficiency gains. Recleaning after polishing is not required provided that a food-grade polishing media and paste is used during this operation.
6. Lubricate. Lubrication is important to protect the tooling and aid smooth operation. A range of oils and greases can be recommended for different applications.
7. Store. Tooling storage and transportation should be specifically designed to minimize damage and deterioration. There are different ways of safely and securely storing tablet tooling; these range from storage cabinets to custom-designed storage containers. Whichever system is adopted, it is important that the tooling is separated to avoid contact and that the tooling condition does not deteriorate during storage.
Application of the seven-step process will have a direct impact on the reduction of many common tablet and tooling problems, thus resulting in a better quality tablet, and can provide direct cost saving for the tablet manufacturer.

I'm playing Dragon Quest IX, and I'm at the part where I just got the boat. What is the fastest way to make a bunch of money? I need about 10,000 to buy the best equipment and grinding takes a really long time when you only get a few hundred per enemy.
Early on the game, the best technique is to fight the highest level monsters that you have access to.
Here are some more techniques:
(Most of these techniques require finishing certain points of the game.)
I choose to make ear cosies. Killing gold golems are more fun but is not very efficient. I am pretty sure making gooey gear is most efficient. To get a lot of slimedrops I go to the plateau by Angel Falls and kill slimes.
I just fight grotto bosses. It's inefficient I'm sure, but you got lots of exp. and a nice bit of gold, and sometimes nice drops (especially legaxy bosses)
Grinding takes a while, but I made 16,500 gold in an hour battling non-stop.
Faffing about using alchemy and buying ingredients will take just as long, and you don't get any of the experience you'd get from battling, so it's an easy choice, really.

In tea, also there is tea powder, which we use. In coffee also, there is coffee powder. Why don't we make coffee in exactly the same way we make tea?
I do make coffee the same way as tea. I just did this morning, in fact. It's called a "French press". Which can also be used for tea ...
It boils down to temperature (pun intended).
According to Wikipedia the ideal temperature to brew coffee is 200°F, which is about 93°C. That is, the temperature is a little below the boiling point of water (which is 100°C). That is just boiling the water and pouring it over the beans will result in too hot a temperature. With a standard coffee machine like this one
the problem is solved elegantly. The heating element makes the water boil. The water then travels up through a tube. This cools the water just enough, such that the temperature is about 93°C when it drips upon the coffee.
Tea, on the other hand, needs other temperatures. Some teas (black tea, Pu'er tea and herbal tea) needs boiling water. Thus one just boils water in a kettle and then pour it over the tea leaves.
See http://en.wikipedia.org/wiki/Tea for tea temperatures.
Coffee and tea are used for similar purposes (hot beverage with caffeine; flavouring in a variety of other contexts) but that is their only similarity.
Tea has more in common with dried oregano, or with cabbage, than with coffee. Coffee has more in common with peanut butter, or perhaps powerded almonds, than with tea.
A better question would be "why is the way we prepare and consume these wildly different plants so similar?" It's a wonder there aren't more differences than the ones you've noticed.

I am trying to find some literature on infinite matrices because I want to know how to get the eigenvalues of infinite matrices. Seriously, it seems there are very few references available. Can someone tell me how to determine the spectrum of infinite matrices?
closed as not a real question by Alain Valette, Qiaochu Yuan, Yemon Choi, Mark Meckes, Andy Putman Oct 16 '12 at 5:35
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.If this question can be reworded to fit the rules in the help center, please edit the question.
One simple example with a special matrix, which has somehow "a continuum" as eigenvalue...
$$ V(x) = [1,x,x^2,x^3,x^4,\ldots ] $$ with a scalar parameter $x$ from the range of convergence, then $$ V(x) \cdot F = f(x) \cdot V(x) $$ This means also: any vector $V(x)$ is an eigenvector of the matrix F and corresponds to the eigenvalue $f(x)$. If now $f(x)$ is entire, for instance the exponential function $ f(x)=\exp(x)$, then any value from the complex plane (except $0$ because $\exp(x)$ is never $0$) "is an eigenvalue" of F contradicting the "naive" extrapolation from the finite truncation of the matrix ...
For me, infinite matrix means an operator on $\ell^2(\mathbb N)$ (or sometimes $\ell^2(\mathbb Z)$, but usually referred to bi-infinite matrix). Concerning the eigenvalues, you thus may just look at the general theory concerning operator on Hilbert spaces, as already pointed out in the comments above.
to present an example: if the considered matrix is the adjacency matrix of a graph, there are relatively involved graph theoretical criteria just to decide whether the spectral radius is an eigenvalue, let alone further spectral values. i think you should make yourself clearer what exactly you would like to know.
I have done some research on banded Toeplitz matrices, (where we consider a sequence of finite matrices, and show where the eigenvalues accumulate). There is also quite old literature on this subject, see references in this paper I shamelessly advertise: http://arxiv.org/abs/1208.5607

Kenny's Farmhouse Cheese in Barren County issued a voluntary recall of four of its 32 cheeses after an FDA inspection revealed there may have been listeria in those products. Listeria can cause serious illness in the elderly, young children, and those with weakened immune systems.
While no cases of illness have been reported, Kenny's didn't want to take any risks with the health of its consumers.
"We've voluntarily recalled all of these products..getting them off the stores' shelves. It is specific to the soft cheeses that we produce," said Kenny Mattingly, Kenny's Farmhouse Cheese Owner.
Kenny's makes about 120,000 pounds of cheese yearly, and only about 300 pounds of that is the soft cheese that was affected.
Those are the Kentucky Blue, Awe Brie, and Tomme de Nena. Kentucky Rose was also included as a precaution.
"I think they like seeing that in a business, that you're working hard to improve and correct problems," said Mattingly.
After responding to the FDA's requests, Kenny's Farmhouse Cheese now meets all requirements.
"We've learned a lot about sanitation and through consultants and through our suppliers about chemicals. We've done environmental swabs from the state milk safety branch recently and found no signs of listeria in the environment. We've really taken care of the problem in our environment," said Mattingly.
Mattingly says they will continue to maintain those standards, and are always seeking ways to improvement.
The recalled cheeses were sold in seven states between Aug. 22 and Sept. 25 this year. Mattingly says all of those products have been removed from shelves at this time.

TOPEKA, Kan. - This week's featured vehicle is a white 1999 Lexus GS 300 4 door. The car has tinted windows. It was reported taken on May 25th from the 2100 Blk SW Westport.
The last four-digits of the VIN are 2536 and at the time it was stolen it had possible Kansas tag 278 AND on it. Anyone with information on the theft of this vehicle or any others is asked to call detectives at 368-9400.
The public can now sign up to receive Hot Wheels e-mail notifications at www.topeka.org/e-subscriptions/index.shtml by checking "Hot Wheels." The public can also sign up to receive the Hot List, a listing of vehicles listed as stolen through the Topeka Police Department which updates several times a week.
Things you can do to help prevent auto theft:
· Never leave your motor running when unattended. This is one of the easiest ways to lose your vehicle, i.e. warm-up thefts on cold mornings, a quick trip into the store, etc.
· Don't loan your car to a stranger or casual acquaintance. Good intentions can result in the theft of your vehicle.
· If you have a garage, use it, and remove the key! If you don't have a garage, park in a driveway instead of the street if possible.
· Steering wheel or steering-column collar locks make visible deterrents, as well as mechanical challenges.
· Never leave a spare key in the vehicle and don't leave the title in the car.
· Keep valuables out of sight, i.e. cellular phones, pagers, backpacks, purses, CDs, valuable clothing, etc. Valuables in plain view are an open invitation for thieves.

The 15 Most Bizarre Animal Mating Rituals
#7. Whiptail Lizards
Native to Arizona, these lizards have apparently been infected with some manner of Sapphic Lilith Fair gene and somehow managed to entirely eliminate the male of the species.
As a result, the lizards are what scientists call "parthenogenetic unisexual pseudocopulators" but what we call "lesbo lizards." Since there are no males, the females reproduce on their own, making exact copies of themselves.
However, proving that porn has many life lessons to teach us, the lizards still need another woman to get the job done. A butchy female, noted by her small undeveloped eggs, will hop on another female who has rich, robust, ready-to-be-lesbianized eggs, and mock hump her lizard brains out while some awesome jazz plays in the background.
#6. Hyenas
The hyena is like that "woman" at the bar with an Adam's Apple, who asks you to call her Steve and does things to you in the bathroom that you'll never speak of to anyone ever again.
An alpha female in the hyena world passes on a super dose of hormones to its young that makes them extra aggressive, which increases their chances of survival. The downside is that all these extra hormones make mom awfully manish and since hyenas can't have man hands, they get the next best thing: a giant clitoris. A giant, 7-inch clitoris that just sticks out making people on safari feel shamed and emasculated.
Weird as that is, the further downside for the hyena here is that the birth canal is inside that giant clitoris, so in effect, the female has to give birth through a penis. This also means the male has to make sweet, awkward, hit-and-miss love to one, which can apparently take months of practice until he can line everything up right. Once the magical moment happens, she pushes him off and puts a cigarette out on his thigh.
#5. White-Fronted Parrots
This is another one of those very few species besides humans that engage in kissing, isn't that just so friggin' precious? When they initiate mating, they snuggle up together and lock lips, which isn't easy when you have those bird lips known as "beaks." However, once the male is pretty sure the lady bird is digging his tongue dancing, he takes things to the next level the way only a true man can. With vomit.
Like so many off-putting video clips from Japan that find their way into our inbox, the birds mix sex and puking in a way nearly half our editorial staff are uncomfortable with.
#4. Bed Bugs
Feel free to not read further as this is the kind of stuff generally found in direct-to-DVD horror films, usually with a title like Drill Rape.
Yes, unlike some animals with their adorable-like-a-Disney-cartoon courting rituals that actually take the time to find the female's genitalia, bed bugs at some point just said "fuck it" and developed the most horrifyingly-named mating practice called "traumatic insemination."
To overcome the female's resistance against getting boned, the bed bug basically just stabs a random hole in her abdomen with his penis and then inseminates her. It is unclear whether "traumatic" refers to the mating ritual itself or just the fact a bed bug is packing a Johnson as sharp as a Ginsu knife.
#3. Anglerfish
The male anglerfish is born as and lives his life as one giant, useless freeloader. This is the boyfriend who'll move in and live on your sofa while he holds out for a job that doesn't require him to do anything.
As soon as the male anglerfish is old enough, its entire digestive system shuts down. Since it can no longer eat or live on its own, it needs to find a woman to mooch off of.
Once it does so, he bites her and releases an enzyme that bonds their flesh together permanently, thus making the male a parasite that lives off the female, releasing sperm whenever she's ready to lay eggs. So, while those teeth make them look badass, the anglerfish is nature's ultimate symbol of clingy wussification.
#2. Porcupines
As you can probably guess, the male porcupine isn't getting any unless the female is good and ready. Not unless he wants hundreds of needles in his dick.
So how does the male get her ready? Well porcupines are apparently very European when it comes to mating, which is to say they piss on each other (no offense to Europeans, we've just seen some movies produced in Eastern Europe and noticed some common themes).
This tiny four-legged animal manages a six-foot-long stream of piss that soaks his potential mate from head to toe. So, accounting for scale, this would be equivalent of a human pissing for over 100 feet, which we think would, in fact, impress some females.
#1. Cichlid Fish
These have to be the frat boy heroes of the animal kingdom, with a mating ritual seemingly designed purely to get high fives from its bros.
After laying her eggs, the female cichlid picks them up and carries them around in her mouth. Some males thus have spots on their lower body that resemble the eggs. They swim by the females, who see the fake eggs and, thinking they have dropped some, try to suck them in.
The male then blows his load in her face and open mouth, presumably while his friends film the whole thing and post it on the internet.
If you're tired of hating animals for getting laid more than you, why not read about some that are genuinely terrifying in our rundown of The 5 Most Horrifying Bugs in the World, and then read about some that are only terrifying once it's too late in The 6 Cutest Animals That Can Still Destroy You.

If $X$ is a smooth projective curve over a field $k$, $V$ is a subbundle of some finite direct sum of $O_X$, then is it true that $V$ is of degree 0?
No. Counterexample: On $\mathbf P^1$, take a (two-element) basis of $\Gamma(\mathbf P^1, \mathcal O(1))$, so that the corresponding homomorphism $\mathcal O^2\to\mathcal O(1)$ is surjective. Its kernel is a subbundle of degree $-1$.
[Really a comment sed hac marginis ... .] a-fortiori's answer disposes of the question completely, but it is possible to go a little further: if $V$ is a degree $0$ sub-bundle of a free bundle on a curve, then $V$ is free (and is a direct summand). Proof: Write $W=V^\vee$, the dual bundle. Say it is of rank $n$. There is then a surjection $\pi:F=\mathcal O_X^{\oplus r}\to W$. Note that $r\ge n$. Choose general sections $s_1,\ldots,s_n$ in $H^0(X,F)$; then $\pi(s_1),\ldots,\pi(s_n)$ will generate a rank $n$ subsheaf $G$ of $W$ [because $\pi(s_1)$ is a nowhere vanishing section of $W$, and then argue inductively on the sheaves $F/(s_1)$ and $W/(\pi(s_1))$]. Then $G$ generated by $n$ sections and is a rank $n$ subsheaf of $W$. Since $\deg W=0$ it follows that $G=W$ and the homomorphism $\mathcal O_X^{\oplus n}\to W$ generated by the $s_i$ is an isomorphism. Dualizing gives the result.

Martin Wesley says: "It's a problem everywhere, especially in Kentucky. We're talking about an issue that's a big problem for adults and obviously it's going to go into teenagers too."
Wesley is the manager of Park Place Recovery Center. He says the results of a nationwide study on teen prescription drug abuse are no surprise. And while these drugs are not illegal they are highly addictive.
Wesley says: "Primarily we're talking opiates, like your Vicodin, Loracet, all those are extremely addictive. Not too far from heroin."
And they are easy to get.
Wesley says: "Most people that are abusing drugs are getting them from many different sources. Grandma's medicine cabinet, many different places."
Rebecca Elrod says: "I'm sure they can get it from their drug cabinet at home."
Elrod is a senior at Bowling Green High school and president of the student government association. She says she was shocked to hear how many teens are abusing prescription medicines.
Elrod says: "I'm definitely drug-free. I've never done anything like that. I'm really proud of that. You know, I have friends who do it, but for me it's completely drug-free."
Elrod is in the minority according to Wesley. He says most teens are trying prescription drugs and that's not all.
Wesley says: "I think the drug of choice right now is not one particular drug, it's actually anything they can get their hands on."
Wesley says parents should keep close tabs on all the medicine in the home and stay involved and active in their teen's life.
He says withdrawl from prescription medicines, painkillers especially, is very difficult to overcome.

Subject: [OMPI devel] OpenMPI multiple ethernet questions ...
From: Muhammad Atif (m_atif_s_at_[hidden])
Date: 2008-06-18 10:44:49
Hi again... I was on a break from Xensocket stuff.... This time some general questions...
Forgive me for the question.... its a quick one and related to some of my development work on Xen, I will explain the rationale after the question. What if I have multiple Ethernet cards (say 5) on two of my quad core machines. The IP addresses (and the subnets of course) are
Machine A Machine B
eth0 is y.y.1.a y.y.1.z
eth1 is y.y.4.b y.y.4.y
eth2 is y.y.4.c ...
eth3 is y.y.4.d ...
Now from the FAQ's (Refer 9: How does Open MPI know which TCP addresses are routable to each other?) it is clear that if I want to run a job on multiple ethernets, I can use --mca btl_tcp_if_include eth0,eth1. This will run the job on two of the subnets utilizing both the Ethernet cards. Is it doing some sort of load balancing? or some round robin mechanism? What part of code is responsible for this work?
Now what if I want to run the job like --mca btl_tcp_if_include eth1,eth2,eth3,eth4. Notice that all of these ethNs are on same subnet. Even in the FAQ's (which mostly answers our lame questions) its not entirely clear how communication will be done. Each process will have tcp_num_btls equal to interfaces, but then what? Is it some sort of load balancing or similar stuff which is not clear in tcpdump?
Another related question is what if I want to run 8 process job (on 2x4 cluster) and want to pin a process to an network interface. OpenMPI to my understanding does not give any control of allocating IP to a process (like MPICH) or is there some magical --mca thingie. I think only way to go is adding routing tables... am i thinking in right direction? If yes, then the performance of my boxes decrease when i trying to force the routing (obviously something terrible with my configuration)
Its related to my Xen (virtualization) work. We are in a scenario, where all the virtual machines on one Xen host need to use eth2 (which is virtualized but optimized for intra-domain communication) and for communication outside the physical machine (i.e. to other Xen hosts) we want to use eth1. Is 'route add' the only way again?
I will ask Xensocket BTL related questions later :)
Best Regards and thanks in advance,
Muhammad Atif

Any one using this yet in 4.0? I have column filters feature configured to show up in all of my columns and I can type a filter string in and click the Filters menu item and the filterupdate event fires. However, when I try to call getFilterData on the filters feature, it does not return anything.
The getFiltersData functions looks like this:
getFilterData : function () {
var filters = [], i, len;
this.filters.each(function (f) {
if (f.active) {
var d = [].concat(f.serialize());
for (i = 0, len = d.length; i < len; i++) {
field: f.dataIndex,
data: d[i]
return filters;
It turns out f.active never returns true .. not even for the current active column.
I am also seeing that the check box for the filter menu is not getting checked. So I am wondering if the two are related and what I am doing wrong.
On the grid, the features property is set as follows:
features: [{
ftype: 'filters',
type: 'filters',
encode: true,
local: false,
autoReload: false,
filters: this.filterData
this.fitlerData looks something like this:
[{dataIndex: 'FullName', type: 'string' }]
Not shown here is the rest of the array but its just all the same thing for the other columns in the grid.
Can anyone take a guess as to why the checkbox for the menu item is not getting checked or why the getFilterData() function is not returning anything?
12 Jul 2011 11:09 AM #2
Found the Problem
After a couple of afternoons trying to figure out why this wasn't working, I finally found the answer.
The problem lies with the onStateChange event in FilterFeatures class. Apparently this event is getting fired twice ... which explains why I was seeing 'filterupdate' fired twice.
This event fires when you click on the check box for a column filter (after entering some text for the filter under normal use cases). When the event fires, it calls setChecked on the menu item, which causes the event to fire all over again. filter.active is passed to the setChecked method, but filter.active never gets set to true. The result is that the first time you check on the menu item, setChecked gets called, passing a false value from filter.active and effectively un-checks the menu item.
Here is the fix:
* @private
* Handler for all events on filters.
* @param {String} event Event name
* @param {Object} filter Standard signature of the event before the event is fired
onStateChange: function(event, filter) {
if (event !== 'serialize') {
var me = this,
grid = me.getGridPanel();
filter.active = false;
if (event == "activate") {
filter.active = true;
if (filter == me.getMenuFilter()) {
//me.menuItem.setChecked(filter.active, false);
if ((me.autoReload || me.local) && !me.applyingState) {
if (!me.applyingState) {
grid.fireEvent('filterupdate', me, filter);
You can compare with the original code in examples\ux\grid\FiltersFeature.js. I commented out the setChecked method, and added some code to look at the event to determine if event was being fired because it is being activated.
I have not tested this thoroughly to know if it is 100% or not but it should be pretty close. As far as I can tell, this entire feature does not work at all without this fix or something similar.

Let K and L be two subfields of some field. If a variety is defined over both K and L, does it follow that the variety can be defined over their intersection?
Yes, if varieties are interpreted as
More precisely, suppose that $k \subseteq F$ are fields and
The same statement holds if $\mathbf{P}^n$ is replaced by any fixed
(Note: this answer does not contradict Pete's. This is just a different interpretation of the question.)
EDIT: As Brian points out, I was indeed assuming that my varieties were closed in the ambient space. The statement about minimal field of definition is not even true for open subschemes in characteristic $p$. For example, if $k=\mathbb{F}_p$ and $F=k(t)$ and $Y=\operatorname{Spec} k[x]$ and $X=\operatorname{Spec} F[x,1/(x-t)]$, then $X$ is the base extension of $\operatorname{Spec} F^{p^n}[x,1/(x^{p^n}-t^{p^n})]$, and hence is definable over $F^{p^n}$ for all $n$, but not over the intersection of all these fields, which is just $k$.
On the other hand, the intersection of any finite number of fields of definition is still a field of definition.
I have generalized to schemes as suggested by Brian.
No, not even for genus $0$ curves, if "$X$ is defined over $K$" means that the variety $X$, initially defined over an extension $F$ of $K$, is to be isomorphic to the base extension of some variety over $K$. (Pete in his answer was implicitly assuming that he was allowed to base extend to an algebraic closure of $F$ before going down to $K$.)
For finite extensions $F \supseteq E$ of $\mathbb{Q}_p$, if $X$ is the genus $0$ curve over $F$ corresponding to the non-split quaternion algebra, then $X$ is a base extension of a genus $0$ curve over $E$ if and only if $[F:E]$ is odd (because $\operatorname{Br}(E)[2] \to \operatorname{Br}(F)[2]$ is multiplication by $[F:E]$ from $\frac{1}{2} \mathbb{Z}/\mathbb{Z}$ to itself).
So if $F$ is an $A_4$-extension of $k:=\mathbb{Q}_2$ (such an extension exists), and $K$ and $L$ are the subfields of $F$ fixed by two $3$-cycles in $A_4$, and $X$ is the genus $0$ curve over $F$ corresponding to the non-split quaternion algebra, then $X$ is a base extension of a genus $0$ curve over $K$, and similarly over $L$, but not over $K \cap L = \mathbb{Q}_2$.
No, not in general. Assuming we start with a variety over an algebraically closed field, this would be true if the variety could be defined over its field of moduli, which would then be the unique minimal field of definition. (In particular it is true if the variety has no nontrivial automorphisms.) Note also that it holds trivially for genus zero curves -- there are no moduli! -- and for genus one curves, by the theory of the $j$-invariant.
Therefore the simplest counterexample seems to be a genus $2$ curve over $\mathbb{Q}$. Mestre has shown that the obstruction to such a curve being defined over its field of moduli is a quaternion algebra over $\mathbb{Q}$ -- i.e., the curve can be defined over its field of moduli iff this quaternion algebra is split, i.e., isomorphic to a $2 \times 2$ matrix algebra.
Let $C$ be a genus $2$ curve with field of moduli $\mathbb{Q}$ and nontrivial Mestre obstruction. (Such curves certainly exist. Let me know if you want an explicit example.) Then $C$ may be defined over a quadratic field $K$ iff $K$ splits the quaternion algebra. By the structure theory of quaternion algebras, $C$ can therefore be defined over infinitely many quadratic fields, but not over $\mathbb{Q}$.
Addendum: Here is a nice paper by S. Baba and H. Granath:
It deals with the Mestre obstruction on certain genus 2 curves and includes specific examples.

How to create a production build with Sencha Cmd (app with sdk 2.0.1) ?
Hi everyone,
I downloaded Sencha Cmd (v188.8.131.52) few days ago.
I have a problem when I want to create the production build of an app created with sencha touch 2.0.1.
I do this in a terminal :
cd path/of/my/app
sencha app build production
It worked well with sencha sdk tools but it doesn't work with sencha cmd.
I think it works with an app created with sdk 2.1 but here is an "old" app (with sdk 2.0.1).
Can you help me ? I saw there was new commands (generate, compile, package...) but i don't know which to use...
Sorry for my english, i'm french
14 Nov 2012 3:32 AM #2
CMD3 is just for sdk v2.1 and up. Previous sdks must be processed with the old sdk tools v2.
So you will have to either upgrade your app to sdk v2.1 or stick with sdk tools v2.
In CMD3 the command to upgrade is from the app folder 'sencha app upgrade ..\sdkfolder'. However upgrading may not work automatically as a lot of things have changed. Make sure you have a copy of your project before trying!! In case it fails you will have to do it 'manually'.
14 Nov 2012 5:11 AM #3
Thank you for your answer, I suspected it a little. Is it possible to make live sencha sdk tools and sencha cmd ? Because I am going to work at the same time on apps 2.0 and 2.1.

I have a problem (a part of a Monte Carlo simulation) where I'm given the energy of an incoming particle, $\varepsilon$ and want to split this energy in two parts, randomly generating the fraction that goes into each part according to a given function
$P(\varepsilon_s) \propto %\frac{1}{\bar E \arctan\left(\frac{\varepsilon}{\bar E}\right)} \frac{1}{1+\left(\frac{\varepsilon_s}{\bar E}\right)^2}$
$\bar E$ is a known shape parameter. Now, the incoming particle can have energies ranging from 0 to a known maximum, $\varepsilon \in \left[0,\varepsilon_{\text{max}}\right]$, but I do not know the energy until the collision event, when I want to split it up, and therefore I can't figure out how to normalize the distribution function properly.
I have a pseudo-random number generator at my disposal which generates uniformly distributed numbers on $[0,1)$. How do I generate random numbers that properly describe how the two collisional products share the available energy?
I've tried reading up on methods for this in available books, but they're all a little to theoretical for me to be able to apply them to my scenario. It's been way too long since I took a proper statistics course, and now it seems I need it :)
Update: As requested, a more thorough description of $P$ (which will get into detail about the physics of this experiment...) follows here:
The physics of this problem is ionization - I have an incoming electron with kinetic energy $\varepsilon$, that collides with a molecule and ionizes it. After the collision event, I have two electrons with energies $\varepsilon_p$ (primary) and $\varepsilon_s$ (secondary), with $\varepsilon_p+\varepsilon_s=\varepsilon-\varepsilon_i$, the latter being the (known) ionization energy. Now, I don't really care which electron is which after the collision, so determining the two energies is simply a problem of dividing $\varepsilon-\varepsilon_i$ into two parts.
To do this, I am using the differential cross section of the collision, as suggested by Y. Tzeng and E. E. Kunhardt1, which is given by them as
$q(\varepsilon, \varepsilon_s) = \frac{C(\varepsilon)}{\bar E \arctan\left((\varepsilon-\varepsilon_i)/\bar E\right)}\cdot \frac{1}{1+\left({\varepsilon_s/\bar E}\right)^2}$
$C(\varepsilon)$ in this epxression is the total collision cross section, which is also known. I'm not 100% sure on this, but if I've understood the physics correctly then normalizing this function over the available energies should give me a probability density. As it turn out, this funciton is normalized so that
$\int_0^{\varepsilon-\varepsilon_i} q(\varepsilon, \varepsilon_s)d\varepsilon_s = C(\varepsilon)$
so normalizing w.r.t. the entire interval is just a matter of removing the factor $C(\varepsilon)$. However, if I insert $\varepsilon=\varepsilon_{\text{max}}$, that gives me a probability distribution which allows for energies higher than the available energy, and if I don't then I don't know how to generate random numbers from the distribution correctly.

《俺が威嚇射撃する ゴーを出したら 突入だ》
I will fire a warning shot, when GO begins (must) rush in.
My shot at figuring out a translation above.
I figure it's something like, I will fire the warning shot, then say go, then we proceed, which is what happens next in the show. Just now seeing how it all connects grammatically.
《瀬文隊長が威嚇射撃後 ゴーの合図で突入します》is spoken right before they go in by another officer. From that it's clear that:
After the commanding officer fires some warning shots, on the signal "go", we storm in.

The world's only Equator Regatta, the Neptune Regatta is back again this year from 10th -16th February 2013, offering expansive sailing challenges and experiences. Whether it be for pedigree racing yachts, family cruiser yachts, catamarans or motor yachts, the Neptune is designed to cater for all categories of experienced sailors who wish to join the elite few who have sprint-raced across the equator.
The Equator, - that imaginary line that separates the earth's northern from the southern hemisphere - divides and influences in many forms: romance, historical debate, sporting prowess, the navigational latitude of zero and even a country's name. Crossing the line has long been held as a seafarer's baptism to the Court of Neptune with ceremonies for the uninitiated going back hundreds of years. Even today whether on a cruise liner, naval vessel, yacht or ship, or even a plane, the attraction and excitement of crossing the equator and subsequent ceremony appeals to young and old.
Aside from the unexplainable desire to cross the equator and check whether the water changes direction when emptying from the galley sink, the regatta also takes participants on a voyage through virgin sailing waters of Indonesia's indescribable beauty.
The Neptune Regatta will take place entirely in Indonesian waters with start and finish at Nongsa Point Marina in Batam (N 01° 11'.86" & E 104° 06'.00"). Nongsa Point Resort is the yachting entryway to Indonesia and is only 11 miles from Singapore.
The Race takes the clockwise course south to the magnificent sailing ground of the Riau islands, south of Batam. Here, volcanic peaks rising in the distance on the larger islands of Temiang, Singkep and Lingga, which rest behind a multitude of tropical islands smaller in size and shapes that lead to the jump off point for the equator at Pulau Buaya (N 0 10'.5" & E 104 13'.5"), which offers protected anchorage and stunning white coral beaches.
The Regatta also takes into account the importance of paying homage to Neptune and allows for a 'time window' of ceremony once each boat crosses the line. On completion of ceremonies or when the 'time window' closes, the race restarts with the Fleet competing for the Trident Cup.
Passage Races through tropical beauty, clear green waters, sailing past breath-taking vistas, combined with a sprint race over the equator, ZERO – THE RACE, altogether make the Neptune Regatta a yachting event unmatched in any sailing calendar.

I am studying the book "Representation Theory" by Fulton and Harris. And I just can not understand the part where they prove the uniqueness of induced representation. If someone could explain it I'd greatly appreciate it! It's on page 33 and it goes:
Choose a representative $g_{\sigma} \in G$ for each coset $\sigma \in G/H,$ with $e$ representing the trivial coset $H$. To see the uniqueness, note that each element of $V$ has a unique expression $v = \sum g_{\sigma} w_{\sigma}$ for elements $w_{\sigma}$ in $W$. Given $g \in G$ write $g \centerdot g_{\sigma} = g_{\tau} \centerdot h$ for some $\tau \in G/H$ and $h \in H.$ Then we must have
$$g \centerdot (g_{\sigma} w_{\sigma})= g_{\tau}( h w_{\sigma})\;.$$
This proves The uniqueness ...
I understand everything until the end, but I just don't understand how this proves the uniqueness... If someone could give me a little more explanation, I would appreciate it! Thanks!

Are the effects additive or subadditive? In many ways, rapamycin acts like a CR mimetic, but even CR can only go so far.
To clarify; administration of rapamycin (a drug) to lab organisms (including mice [1]) extends lifespan. Similarly, restricting the intake of nutrients to the minimum without causing malnutrition also extends lifespan in lab animals (including primates [2]).
Rapamycin inhibits the mTOR pathway (mammalian Target Of Rapamycin) - specifically mTORC1 (Complex 1) - which influences protein synthesis, autophagy and inflammation (among others). Upstream factors of mTOR include nutrient availability and insulin signaling (see "Deconvoluting mTOR biology" for good review [3]).
It has been hypothesized that the lifespan-extending effects of caloric restriction (CR) are mediated by mTOR (one can see why - mTOR is affected by nutrient availability). In fact it may depend on the method of CR;
Greer et al [4] report that different methods of CR in C.elegans, for instance feeding them a diluted food source, or conversely feeding them on alternate days, do not necessarily require the same genetic pathways. Not only this but CR combined with a genetic mutant (eat-2) have additive lifespan-enhancing effects.
So whilst the evidence is not concrete, and I look forward to other studies in mammals similar to the one by Greer et al, it looks as though rapamycin and CR have similar but not exactly the same effects on lifespan; rapamycin specifically inhibits an individual pathway which is involved in many processes, and some of its effects are not necessarily desirable (e.g. rapamycin inhibits the immune system [5]). On the other hand, CR (most of the different types) seems to be mediated by mTOR - this difference is critical: mTOR is not necessarily inhibited by CR, it is just required for its effect.
Therefore combining rapamycin and CR is unlikely to have an additive effect as rapamycin may override any influence CR has on mTOR signaling, but I have not seen a study in which this has been tried. Combing different methods of CR (or developing drugs to do just that) may well have additive lifespan-enhancing effects.

I have created an Open Source implementation of StackOverflow.com. It's very early and I haven't done all (obviously) of the features that StackOverflow has. But I will with time.
Are there others that would want to have access to something like this?
If so, what would be the features you would expect it to have? What license would you want it to have?
I have created a small blog where I talk about Stacked and there's even a video featuring a demonstration. You can register (without confirming your email address), so please play around with it and give feedback about what you think.
The reason why I did this is because I started using StackOverflow.com just this week and I was instantly addicted. StackOverflow is the way people should communicate when they need help. And I wanted this for myself for Ra-Ajax as our primary forum mechanism.
I think Joel Spolsky and Jeff Atwood created a brilliant way to help others and ask for help. I want the rest of the world (including me - and the users of Ra-Ajax) to also have access to a system like this.
Yet to be implemented:
- comment support
- RSS (or Atom?)
- better ways to browse profiles
- editing profiles
- email confirmation when registering, etc.
Most of the "core" features of StackOverflow.com have been implemented.
The code is ASP.NET using ActiveRecord and Ra-Ajax (obviously).
There's about 1000 lines of code and the code can be found at the Google code project page - though I haven't created a release yet. But you can access the SVN anonymously.
Give me feedback please.

Young Leaders,
Do you have a passion for building strong and resilient rural communities? Do you think about the future and what is in store for rural people and places? If so, join us on November 3-5, 2013 at The Cornhusker, A Marriott Hotel in Lincoln, Nebraska for the 2013 Rural Futures Conference and participate in the dialogues around these very issues.
The theme for the 2013 Rural Futures Conference is Beyond Boundaries, which encourages all of us to step beyond our typical boundaries and work together to create positive rural futures. While moving beyond boundaries can be challenging and even ominous, it also provides the unique opportunity to implement a foundation of collaboration that can impact the future of rural people and places. The upcoming conference will celebrate the importance of rural and create energy and enthusiasm for new and innovative ways to address complex opportunities and challenges. From University faculty, staff and students to community citizens and organizational partners, don't miss the opportunity to transcend boundaries and collaboratively make a difference.
There are several opportunities for you to be involved in and even contribute content to the 2013 Rural Futures Conference. We encourage you to share your own knowledge and expertise at the conference to help us explore new ideas, discover synergies, and facilitate partnerships. Please consider being involved with one or more of these opportunities during the conference, and encourage others to become involved as well.
Quick Pitch Spotlight: Conference participants rapid fire their "big idea" for rural people and places.
Community Questions: Communities of place or interest pose questions that stimulate collaboration and potential research opportunities.
Undergraduate & Graduate student poster competition: Participants display current work or research relevant to the rural futures. Abstracts are due September 13, 2013.
Registration opens on September 1, and will remain open until the seats are filled. Registration closed early last year because maximum capacity was reached, so register early to ensure your spot. For more information or to register, visit ruralfutures.nebraska.edu/conference.
Students interested in attending, but who are unable to pay the registration fee, should contact Kayla Schnuelle (firstname.lastname@example.com) for information about a limited number of student scholarships.

What's the easiest, fastest, surest way to score an Ingress invite, or is the signup at the Niantic site the best bet?
Define an easy way, I know some people who just sign up for an invite at Niantic Labs and got their invite. As far as I know they constantly send new invites through several channels, and as the game gets massive, I guess the number of sing up invites sent will only get bigger.
It is also a lot of fun to make a fuzz :)
Update: There are several ways to get an invite to ingress:
In order of speed to get an invite:
Ingress Artwork
This seems to be a popular method to catch attention of the Ingress devs, so I will elaborate on it further.
Sharing the picture
Make sure you share it to the #ingress and #ingressinvite tag. Most people also specifically add some of the Ingress developers, Brandon Badger, Brian Rose etc. ... check the successful re-shared posts in #ingress who got the invite.
Artwork Features
This is just my observation of common traits in the accepted graphics, I don't know of a particular 'acceptance criteria' as it is basically a question of whether Niantic sees & likes it.
All of the tricks mentioned in above answers are what everyone says. But if you want to have the activation code faster, then you can try this method which worked for me.
The trick is to periodically check
Just to mention I bought my Android phone on 1st Jan and got the activation code on 5th Jan. Nothing else can be faster than that. ;-)
Almost all big cities have an Ingress Google Plus Community interested in recruiting new members. For instance, San Diego, CA has:

The future lies in local planning
Published: Thursday, August 15, 2013 at 4:30 a.m.
Last Modified: Wednesday, August 14, 2013 at 6:40 p.m.
Henderson County has established a strong process for communities to guide development in years to come, as evident by the planning effort now underway in the southern part of the county. Residents of Green River, Tuxedo and Zirconia, like those in Dana, Edneyville and Etowah-Horse Shoe before them, are working to create such a plan for their area.
About 40 residents and property owners turned out Tuesday to peruse a draft plan and zoning maps for their area. Their generally positive response is a sign that county planners are on the right track. Ken Allen, who owns a Tuxedo hair salon and antique store with his wife, Brenda, had only one criticism. My take is they shouldve come to the community 15 years ago to ask for our input, he said.
The couples store and other properties along Old U.S. Highway 25 near the lake would be rezoned from residential two rural to local commercial under the draft community plan devised by an advisory committee of residents. The plan also recommends that 71 percent of the area about 26,000 acres be rezoned from residential three to residential two rural. If approved by commissioners, this would allow an owner of five acres to build five homes instead of the three allowed under current zoning, and it would reduce building setbacks from 15 to 10 feet.
The plan for the Green River, Tuxedo and Zirconia communities, known by the homey acronym GRTZ, sets goals for future land use, infrastructure, agriculture, housing and economic development. It began with a meeting last September that drew about 80 residents and continued with an online survey that allowed residents to express their wishes for the future.
The advisory committee could finalize the GRTZ plan as early as Sept. 10, said John Mitchell, the countys business and community development director. The plan will then go to the county planning board and finally to county commissioners for approval.
This process is effective because it is proactive it allows residents and property owners to have a say in how their communities develop while the area remains largely rural. It is much better for residents to consider these matters before their community faces major development pressures rather than wait until some major project is proposed that they may or may not want.
The process also helps establish common community concerns and goals. Both the Village of Flat Rock and the Town of Mills River were established in large part because the county, at the time the municipalities formed, had little meaningful local planning. Etowah and Horse Shoe were exploring forming a town, too, when the community planning process commenced for those areas.
Community planning has its limits and does not eliminate conflicts. For instance, residents want to preserve the areas rural nature and water quality, but they also are concerned about excessive regulations. People bring different sensibilities to the process. Through communication, cooperation and compromise, though, residents can have a strong say in what they want for the future.

St. A professor: Private prisons cheaper, less safe and competent
�There is a systematic failure to provide the level and competency of staffing necessary to run facilities that are safe not only for the people on the inside, but the public,� said Elaine Rizzo, a criminal-justice professor at St. Anselm College in Manchester, New Hampshire, who studied prison privatization for a state advisory board. �It comes back to saving money.�
