There are multiple technique out there, with the two I mainly use being breastroke and freestyle. Is there a difference between the two as far as their effectiveness in a cardio workout? Is there a technique that stands "supreme" for cardio, or is swimming in general just effective?

There are four major strokes in swimming:
Of these, freestyle is the fastest and most efficient swimming style. In my own experience the butterfly stroke is by far the hardest to maintain for long distances. How you fill in your workout depends on two factors, how well can you swim and how hard do you want to be working out.
How well can you swim?
If you have a poor technique or a poor condition, swimming will become quite heavy to sustain at a decent speed very quickly. The poor technique causes you to swim inefficient, because having a wrong posture creates a lot of unnecessary drag and inefficient breathing. The poor condition means fatigue will have a negative influence on both your speed and your technique. A combination of both will lead to a complete downward spiral.
Why should you care? Well, the point is you want to be swimming for a long stretch off time, enough for some real cardio-exercise. You don't want to be 'wasting' energy and end up completely wasted half way through. You should only make it harder on yourself once yourself once you have a decent baseline condition. Pick the strokes that allow you to swim for as long as possible.
How hard do you want to be working out?
Like running, swimming is something you can make as hard as you want to. If you swim faster, it will cost you more energy. You can also add tougher strokes (like butterfly stroke) or add resistance (wear a t-shirt or use paddles) to increase the resistance. The other option is working out longer, though unless your serious about swimming long distances, I reckon this is the last option for everyone.
Why should you care? This means that if you always swim for half an hour and you're swimming condition + technique start to improve, you can either do more in those 30 minutes or add some minutes to make it harder.
So say your already capable of swimming half an hour non-stop, what should you be doing? As with every other workout, you can either try to swim faster (more miles/hour) and just swim non-stop or use interval training to push yourself harder during short stretches of time combined with periods of relative rest.
For pushing yourself faster, I'd recommend the latter. Though you should always combine it with 'rest' days where you simply swim non-stop and perhaps focus on improving your technique rather than pushing for speed.
A 'typical' swimming workout with intervals could consist out of a 400m warming up, it doesn't really matter what stroke you swim, just that you get your heart rate up to a nice and steady level. Then you start swimming 100/200m intervals, you have two options with how to approach these:
You could also try to focus on swimming faster for longer stretches of time. An often used method for this is using a 'pyramid' built up. It basically goes like:
100m --> 200m --> 300m --> 400m --> 300m --> 200m --> 100m
Which totals in 1600m (not bad!) + 400m of your warming up. Swim each interval as fast as possible (under the lactate threshold), but try to keep up a constant pace rather than ending very slow. This teaches you to spread your efforts when the workout starts to become longer and will help you find a pace of breathing and stroking that you can keep up for longer stretches of time. You can use the same protocol as with the 100m workouts, if you aim for 1:45 min with rest, just multiple that for every 100m you swim. This means your need to swim the 400m within 7 minutes and you get the rest of the time to rest.
You can shorten your 100m time, but you can also switch the resting for swimming 50m backstroke. This gives you less rest, but you don't have to push yourself to swim much faster (which is often much harder!). Alternatively, you could do a medley, where you combine all strokes. The recommended order is: butterfly, backstroke, breaststroke, freestyle, because it has a good mix of intensity and 'rest'.
So my advice: always swim freestyle unless you want some variation or rest.
Strokes like freestyle, backstroke, and breaststroke use your abs, glutes, biceps, triceps, quads, and hams. It's basically a full body workout which is excellent cardio. Like Eelvex said, switch it up. If you do the same exercises, in or out of the pool, your body will adapt and you wont be burning as many calories as you potentially could.
What do you mean when you say effective? Burning the most calories? Working the most muscles?
If it's working as much of your body as you can, obviously you want to mix in several styles.
If you are just looking at it as a calorie-burning/resistance-training thing, it really comes down to what gets YOUR heart-rate up and allows you to train longer and safely push yourself. The rhythm is very important, the style.. not so much.
If you seek to increase resistance of a certain muscle group, then focus on that weak spot; if you seek to increase general cardio-resistance, mix it up so that you can swim longer. Otherwise just enjoy being in the water and don't worry about it :)
Of the two strokes you say you know, breaststroke is very difficult to learn to swim fast, and certainly hard to use as a cardiovascular exercise for any significantly long time. Assuming (by the fact that you only know half the strokes) that you are not a competitive swimmer, freestyle is best for you.
To add to [Ivo Flipse]'s1 answer: in addition to swimming longer distances, like that 1-2-3-4-4-3-2-1 set, another good cardio set is to do shorter distances in many repeats. For example, I like to do 10x100 free or 10 or 20x50 on an interval that keeps my rest down to 5-10 seconds (for 50s) or 10-15 seconds (for 100s). These days, for me, that is about 45" (long course) and 1'25"; what it is for you, you'll have to experiment for yourself. This way, you get your pulse up to a high enough rate to be close to the anaerobic threshold, yet give yourself enough rest between to be able to swim at that speed for longer than just, say, a 100 metres.
And if you are good enough at breaststroke, you can use it too in a set like that.
If you get more serious about swimming, you should see if your local swim club has a Masters (adult swimming) program and learn the two other strokes so you can swim those 10x100s medley. That really gets the pump going. Good luck!

MANHATTAN, Kan. (WIBW) -- After decades spent serving and protecting the community, Manhattan Fire Chief Jerry Snyder is retiring.
Snyder celebrated 36 years with the Manhattan Fire Department. He started on Jan. 3, 1977 and worked his way up the ranks, becoming chief in September of 2005. His retirement was effective February 28, 2013.
He issued the following statement to WIBW as he marked the end of his long career: "Throughout my years of service the Manhattan Fire Department has been blessed with outstanding support from our citizens, city manager's office and elected officials. I appreciate City Manager Fehr giving me the opportunity to lead the department and for all of his support towards accomplishing our mission."
"It has truly been an honor and privilege to work for the Manhattan Fire Department and to be able to serve the citizens and visitors of Manhattan. I look forward to being able to continue to serve them in other ways now," he added.
A reception for Snyder was held March 1, 2013 at the Manhattan Fire Department's headquarters on Denison Avenue.
MFD's Deputy Chief of Operations Scott French has been named Director of Fire Services for the City of Manhattan in the wake of Snyder's retirement.
French will be responsible for assuring that the City of Manhattan has a professional fire service organization that can effectively function during all types of emergency incidents, including staffing five fire houses and managing the recruitment, selection and training/education of all personnel in the department. He will direct the enforcement of the Uniform Fire Code and other fire safety related ordinances and laws to residential, commercial and educational properties and groups by assuring a thorough program of fire and safety inspections and public education activities. French will also be responsible for administering the City's building and housing codes as well as nuisance and other code ordinances.
"I would like to thank Chief Jerry Snyder for his dedication and leadership that he has provided to the Manhattan community and wish him the best on his well-deserved retirement," stated French. "I am honored to be given the opportunity to lead a highly respected fire department in such a great community."

Vermeil Plating:
Pronounced "vermay," vermeil is an electroplating process in which 14K gold or higher is coated over sterling silver. Officially designated by the jewelry industry, items may only be sold as vermeil if they have a minimum thickness of 100 millionths of an inch (2.5 microns) of gold over the silver. Regular gold plating is less than 2.5 microns.
The "vermeil" technique of plating sterling silver with gold originated in France in the 1750s. It differs from "gold filled" or "gold plated" in terms of the thickness or thinness of the microns over sterling silver. "Gold filled" pieces have a much thicker layer, between 15 and 45 microns, which is mechanically bonded to the base metal with heat and pressure. Vermeil is a more expensive version of "gold plated". It does not wear off as quickly as gold plating does. However, over time, vermeil wears off and therefore will require re-plating.
Gold/Platinum Embraced Silver or Bronze:
Our platinum and gold embraced collections feature layers of platinum or gold over sterling silver or bronze for a lustrous, radiant finish everywhere you look and touch.
To care for your plated jewelry items:
Named from the French word for lemon, "citron," citrine is a variety of quartz available in a range of golden hues from lemon, to straw, to sun yellow, to deep gold, to orange, brown and deep red. Darker colors are more highly valued, including the medium golden-orange and dark-sherry colors, sometimes called Madeira citrines after the color of the wine.
Citrine crystals can form together with amethyst to form ametrine, or with smoky quartz to form bicolored quartz. Citrine is generally less expensive than amethyst, and is also available in a wide range of calibrated sizes and shapes, including very large sizes. Considered an alternative to topaz as the birthstone for November, it is also thought to be the traditional gift for couples celebrating their 13th and 17th wedding anniversaries. Citrine ranks a 7.0 on the Mohs Scale, and because of this durability, it is ideal for jewelry wear.
Almost all citrine on the market is heat-treated amethyst, and generally starts life as either smoky quartz or amethyst geodes. Heat treatments first turn them clear and then give them a permanent color ranging from yellow to brownish-red. In some amethyst deposits, the amethyst has been partially or fully changed to brown citrine by natural means of heating, thereby transforming it into citrine. Natural citrine is pale yellow to orange, and occurs in much lighter hues than the heat-treated material. Citrines whose colors have been produced by artificial means tend to have much more of an orange or reddish caste than those found in nature. Since most citrine was originally amethyst that was heated to turn its color to gold, both citrine and amethyst jewelry should be kept away from prolonged exposure to strong light or heat.
Citrine is found in volcanic rocks and quartz veins and owes its color to the presence of iron. Most citrine is mined in Brazil, but almost all of the Brazilian material is heat-treated amethyst. Supplies are most plentiful in the Brazilian state of Rio Grande do Sul, particularly from the Serra Mine. The Ira' Mine also produces large quantities of the gem. Citrine can also be found in the Ural Mountains of Russia, in Dauphine, France, and in Madagascar.
In ancient times, citrine was carried as a protection against snake venom and evil thoughts. It was thought to give calmness and mental balance to its wearer. Throughout history, people have confused citrine for topaz. Many citrines were sold as topaz and thus thought to carry the same qualities, such as knowledge and beauty. Today, citrine symbolizes truth and integrity, and is believed to promote creativity and personal clarity. It is also believed to impart happiness and cheer to its wearer while raising self esteem, as well as cleanse, regenerate and attract abundance.Zircon:
Zircon often suffers for its name's similarity to "cubic zirconia," the simulated diamond. The stone zircon, however, is actually a beautiful natural gemstone. It is named from the Persian word "zargun," meaning "gold-colored." This is despite the fact that it comes in a wide range of rainbow colors. The majority of zircons are brown or yellow-brown, while pure red and green are the most valuable colors. The yellow-red to reddish-brown variety is called "hyacinth."
For many years, the most popular type of zircon was the colorless variety. More than any other natural stone, colorless zircons produce a brilliant sparkle similar to diamonds. The most popular color today tends to be the bright pastel blue variety. Sometimes called "starlite," blue zircon has recently become considered an alternative birthstone for December.
Zircon is one of the heaviest gemstones, meaning that it will look smaller than other varieties of the same weight. It ranks a hardness between 6.5-7.5 on the Mohs Scale and is mined in Cambodia, Sri Lanka, Thailand, Myanmar and Australia.
Travelers during the 11th century wore zircon amulets for protection and to encourage welcome greetings on their journeys. In the Middle Ages, the stone was said to bring wisdom and prosperity to its owner. Hindu mythology even mentions the gem when referencing the Kalpa Tree, which was a glowing tree covered with gemstone fruit and leaves of zircon.

Since the upgrade on the Purple boot screen I am getting a simple text Ubuntu 12.10 over 4 small pulsing dots
in 12.04 I was getting an image and not text- does this mean anything is wrong?
As long as your system boots and shows a GUI after this screen, you should be fine. With that said, you may not be able to access the
In a nutshell, it won't hurt anything, but if something breaks, it may be harder to fix it.
Have the same issue on one of my older boxes. A while ago I read in the ubuntuusers.de wiki it's simply because some Nividia graphic cards/drivers lack support for that type of graphic during boot. Tested it out on an box with Intel graphics and it worked just fine.
So I think it's no big problem other than it's not that nice looking.

There are infinite graphs which contain all finite graphs as induced subgraphs, e.g. the Rado graph or the coprimeness graph on the naturals.
Are there infinite groups which contain all finite groups as subgroups?
There are infinite graphs which contain all finite graphs as induced subgraphs, e.g. the Rado graph or the coprimeness graph on the naturals.
Yes, plenty. The group only has to contain all finite permutation groups. Perhaps the most straightforward example would be the permutations of a countable set. That is bijections which fix all but a finite set.
There is a finitely presented group which contains all finitely presented groups, as proved by Higman.
There many examples for instance the direct product of all finite groups. A more interesting example of a finitely generated (topologically) profinite groups is $\Pi_{n \geq 5} A_n$. Of course you can also construct many examples using direct limits of finite groups.
Another interesting example is the Nottingham group which is for $p>3$ a finitely presented pro-$p$ group (proved by Mikhail Ershov) which contains every countably based pro-$p$ group (proved by Rachel Camina and aslo by Ivan Fesenko) and in particuar every finite $p$-group. Of course it does not contain every finite group, but still in the spirit of your question. The Nottingham group has many other remarkable properties and is a worth knowing example of a pro-$p$ group.
Here's a finitely generated group that contains all finite groups: permutations of the integers that are almost shifts; that is, each permutation differs form the shift-by-$n$ permutation by a permutation with finite support. This maps to the integers with kernel Bruce's group. Is it finitely presented?
My favorite is Thompson's group $V$.
My favorite picture of $V$ is to take a set $X$ which is a disjoint union of subsets $L$ and $R$ having fixed bijections $l:X\rightarrow L$ and $r:X\rightarrow R$. Finite words in $l$ and $r$ map $X$ to "fragments" of $X$. Two "fragments" $W$ and $U$ that are the images, respectively, of words $w$ and $u$ in $l$ and $r$ are connected by the bijection $uw^{-1}:W\rightarrow U$. The two "fragments" will be disjoint iff neither of $w$ nor $u$ is a prefix of the other. If this condition holds, let $(w,u)$ represent the permutation on $X$ that is $uw^{-1}$ on $W$, is $wu^{-1}$ on $U$, and is the identity elsewhere. The group $V$ is generated by all such $(w,u)$. It is finitely presented and contains all finite groups.
Other f.p. groups containing all finite groups are known as Houghton groups. See the section on Houghton groups K. S. Brown "Finiteness properties of groups" in Journal of Pure and Applied Algebra, 44 (1987), 45-75. I forget how they are indexed, but from about n=3 on up, they are all f.p.
If you want your group to be countable, you may consider the direct sum of all S_n's.
Another interesting example is Hall's universal group
Hall's universal group is a countable locally finite group, say U, which is uniquely characterized by the following properties.
In the same spirit, there do exist infinite groups, all of whose proper subgroups are finite: the Tarski Monster. Are there any other "easier" examples?
I can't resist mentioning that the group of unitary elements in the hyperfinite $II_{1}$ factor (The group von Neumann algebra of Bruce Westbury's "locally finite" permutation group above) in fact contains every countable discrete amenable group as a subgroup.

Does anyone have any predictions about the new Kindles?
We're probably getting a Kindle sometime soon, but I've been reading that new Kindles are expected to be announced soon, probably in September.
Perhaps in preparation for this new round of gear, lots of sites (including Cowboom a week ago, and Amazon today) are doing sales on their current and older model Kindles and assorted accessories.
We're probably holding off on buying till we see these new models, since some of the rumors include:
- a September announcement
- some new e-ink models with front-lit screens for reading in low-light environments
- a larger Kindle Fire (eg to compete with the iPad's screen size)
I think that front-lit e-ink screen is a key feature for us, since we read in bed at night.
Any other ideas / wishes / predictions about the new models?
12 Answers answer
they'll sell a lot of them?
Hopefully one with a micro sd slot OR one wit more storage than 4gb...
I can't think of any feature that would entice me to replace my 2nd generation kindle that works perfectly fine.
I have his and hers reading lights mounted above my bed for night time reading.
A friend at work was just pointing out that the Kindles can only read Amazon's e-book format, while Nooks and Sony readers etc usually can manage multiple formats. So that's something to consider.
I think the lack of a microSD slot in the Fire really disappointed a lot of Android power-users. But I think Amazon would still prefer to go without it, the better to force users to buy streamable content from them.
But despite all that, I think if they have an e-ink Kindle with a front-lighted screen that would be an easy "buy" for us. We have bed lights too, but it's hard for one of us to sleep while the other has their light on.
They will be over priced
Definitely think a larger Kindle Fire will be out. I think it's less to compete with the iPad cause iPad buyers are going to be iPad buyers - you're not going to win that fight. I think it's a platform that sets them up for better movie/TV streaming content as well as newspaper/folios/magazines periodicals, and textbooks. The smaller screen isn't as good for etext books. Yes, the DX will probably get discontinued which is not unexpected since it's been neglected since launch.
I wouldn't be surprised if they got rid of the Kindle Keyboard and in favor of the Touch. And yes, a front lit screen would be nice, too.
I doubt they'd put in a MicroSD card slot because they're all about the Amazon cloud and streaming and that doesn't fit into the model.
One thing I'd like is to be able to change the screensave to whatever I'd like. Maybe Amazon should hook up with a photo hosting site and allow us to use one of our own photos.
@mkentosh: Actually the entry-level Basic and Touch are really affordable if all you want is an e-reader.
@first2summit: Agree on most of your points. I don't want to have to hack my tablet in order to customize things like the screensaver.
ACCESS to the ENTIRE android market (Google Play). What's up with that AMAZON.
@gthuffines: Kindle Fire's really not too different than the iPad - both walled gardens. Things are great but in their worlds whether it's Jobs' or Bezos'.
I like my 3rd gen keyboard kindle just fine for my e-reader needs. I may look into the new Kindle Fire if it has decent performance as a tablet.
A larger Kindle Fire would be nice, especially if it has a micro SD slot. Streaming doesn't work well in this part of the country. :(
color e-ink would be nice.
I'm pretty happy with my kindle fire but yeah, more storage space or an sd slot would be swell.
Maybe hdmi out? Would be nice if my kindle was a netflix box as well.
I could see them doing a 10 inch kindle fire, maybe. The 7 inch sells so well though, maybe they won't.
It would be nice if the next one has a few buttons. The lack of buttons can be irksome.
And Google Play isn't a walled garden? Please. We are at the point now with mobile device markets where we were with desktop computer file formats in the mid-90's before linux was mass-marketable and open and cross platform applications were bandied about as the next big thing.
The goal now is to create a device with built in obsolescence (no replaceable parts like batteries and screens), no upgrade path (must buy new model for new features) and no 3rd party expandability (iCloud/Amazon Cloud/Google Drive and no sd slot).
It's obscene and every PTB managing these companies should be ashamed of themselves. /soapbox

The 8 Most Awkward Sexual Moments in Comic Book History
#4. Lois Lane and Lana Lang Brainwash Superbaby Into Loving Them
Back in the 60s, before Lois Lane and Superman tied the knot, Lois and Lana Lang used to be in a continual battle for Superman's affections and would go to extremely insane lengths to get his attention. Easily the creepiest, most disturbing plan they ever had was to brainwash Superman into loving them, as a baby.
This isn't part of the brainwashing. It's just a really weird thing that also happened.
The story starts with Superman saying goodbye to both girls as he is going to his Fortress of Solitude to do youth-restoring experiments. A few hours later, Lois finds Superbaby on the street and assumes Superman has gotten himself stuck in child form.
Instead of trying to get Superman back to normal, Lois and Lana both decide to take advantage of the situation and hypnotize Superbaby into loving each of them so he will marry them when he goes back to normal, because everyone knows that brainwashing is the foundation to a loving, lasting relationship.
Nothing weird here.
But they don't just leave a short hypnotic message in the kid -- they full on condition him to be their love slave, making him practice proposing to them, kissing them on the cheek and feeling like he genuinely loves them.
"I'm going to fuck that baby! Haw!"
The manipulative, rapey nature of this whole plan is almost too much to believe. If the true horror of this isn't sinking in, pretend that it's two adult men brainwashing a young girl to love and kiss them against her will when she gets older, and suddenly, we've reached into story lines that even German porn won't touch.
When Superman shows up the next day, de-babified and unhypnotized, the girls freak out, thoroughly pissed off at Superman that all that brainwashing they did was for nothing.
How about, on the way, you tell me once more what the fuck you did?
Superman is oddly OK with the fact that they tried to brainwash him, but he is curious anout who that Superbaby was, so he takes the girls back to his Fortress, where one of his super-machines explains that Superbaby was from a different dimension and returned there when he aged back to normal. As a creepy bonus, we find out that their brainwashing actually worked and that the Superman of that reality has proposed to both of them. It's legal in that universe.
Superman seems fine with the idea of an alternate version of himself living a lie and being married against his will and laughs at the whole thing, ignoring the fact that it easily could have been him stuck in a relationship with the two manipulative bitches.
"Everyone would be cool if we just ... kept watching through the honeymoon, right? It's not just me who's curious, yeah?"
#3. Green Lantern Dates a 13-Year-Old
Hal Jordan, the Green Lantern, is basically considered on equal footing with Superman when it comes to the whole righteousness and high moral standards thing, which is what made it so weird when Hal started dating a 13-year-old member of the Green Lantern Corps.
Green Lantern Dating Tip: Future sexual prospects love it when you call them "little sister."
Her name was Arisia, and she was an alien who came to Earth to help fight off the ridiculous number of villains we have on our planet. She was also completely in love with Hal, which she made clear as frequently as possible.
Aaaaand jailbait.
To be fair to Hal, he took her aside eventually and told her to back the fuck off and go after boys her own age before she got him into shit over her crush. She tried to argue that she really loved him, but eventually she was shot down and ran away in tears.
So, that's that then -- he broke a little girl's heart, but his integrity is fully intact. Nice work. Well, at least it is until Arisia uses her Green Lantern ring to make her body age itself into a fully grown woman in a matter of hours, and that changes everything!
"... a 13-year-old woman. Really unfamiliar with the space laws, on this one ..."
OK, so physically she looks older now, but that doesn't change the fact that she's still mentally and emotionally only 13. Hal explains to her that even if this was OK (which it's not!), he's not going to date anyone right now, as his girlfriend, Carol, has recently died. And on this point he is very firm, and sad.
Hal's iron will is able to fend off Arisia's advances for a whopping three more pages, when the rest of the Green Lantern Corps comes to rescue the two of them and finds:
"Look, I know we're just a stuffed beaver and a few pig monsters, but this is seriously fucked up."
So apparently all that morality and righteousness garbage goes flying out the window when developed breasts and long legs are involved. Arisia still has the mind-set and life experiences of a girl just 13-years old, but Hal, an intergalactic space cop, says, "No, yeah, I know, but still: titties." Then they date and act like the rest of the team are being assholes for questioning their relationship, as though this wasn't basically statutory rape.
So Hal's happy, Arisia's happy, and the readers at home are left shifting uncomfortably and wondering whether they have to turn these comics in to the cops as some kind of twisted child pornography.
#2. Superman Wants to Marry His Teenage Cousin
In this early Superman story, we find Superman's first cousin, Supergirl, starting to get worried that Superman will never choose a wife and will end up alone forever. He tells her that he's never going to get married, so he can devote his life to defending Earth, to which we Earth residents say, "Awesome!"
Deciding that meddling in his life in a totally unrequested way is her only obvious choice, she starts trying to set Superman up with famous women in history and other superheroes, all with disastrous results. She apologizes to her cousin for meddling, and we then learn the creepy truth -- that Superman isn't as opposed to marriage as he previously said, it's just that he totally, definitely wants to marry his cousin. Oh, and by the way, she's 16, just in case this wasn't quite creepy enough as is.
Superman makes it perfectly clear that if it wasn't against the law on their home planet, he and Supergirl would be knocking Super-boots right now. Hell, from the looks of things, he can barely restrain himself from pouring them some wine and having a two-person tango right there in the Fortress of Solitude. Still determined to get Superman a wife, Supergirl steals a play from the previously discussed creepy Superman comic and finds an exact copy of herself in an alternate dimension that is all grown up and suggests that Superman go marry that girl.
Man what an unsophisticated computer.
Instead of waving off her childish love fantasies, Superman thinks this is a great chance to fulfill his lifelong cousin-marrying fantasy and flies to the alternate reality, where he immediately starts macking on the clone of his cousin and asks her to marry him, no questions asked. Not even "Have you been tested lately?" or "Have you been my cousin forever?" Superman ends up being incredibly happy with his pseudo-cousin, and it seems like things have wrapped themselves up nicely in a beautiful, creepy bow.
The only reason we don't currently read Superman and the Adventures of his Cousin/Wife is because the girl can't survive on Earth, so Superman has to leave her behind, destroying that random parallel-universe Supergirl's life and leaving Superman completely emotionally wrecked. In the end, there's a whole lot of crying, some unresolved sexual tension and Superman flying away sadly, still pining after his teenage cousin.
Yeah, here's your superhero, folks -- a shining example of moral integrity. Don't worry about him being near your daughters, though -- he only likes people he's related to. You're good.
#1. Nightcrawler Dates His Sister
In the early days of X-Men, Nightcrawler's origin was a mystery, until the team got dragged into hell by Margali, Nightcrawler's adopted, gypsy mother, in order for him to go on trial for killing Margali's son, Stefan, who was Kurt's adopted brother.
During the middle of Nightcrawler's hell-trial, his adopted sister Jimaine, who we assume must have just been taking a casual stroll through hell at the time and came to see what was going on, appears in Kurt's defense. All three kids, Kurt, Jimaine and Stefan, were raised from birth together until they were in their 20s, but Kurt hasn't seen Jimaine in years, as he thought she also blamed him for killing their brother and had abandoned him. Kurt finds out he was very wrong about his sister, but very soon the readers at home begin to wish he had been right.
Kurt is found innocent, and they are all returned to Earth where Kurt asks his sister where she's been all this time. The answer is more disturbing than pretty much anything we could ever make up, as she reveals to him that she's actually been around for several months, disguised as a regular human named Amanda Sefton.
Why is that such a big deal? Amanda Sefton is Nightcrawler's girlfriend, and they've been banging for the last few months, which means that Kurt's sister secretly started dating him when she was fully aware that they were brother and sister the whole time. Sure, they're not related by blood, but they had been raised together since Kurt was "barely an hour old," and it doesn't matter what anyone tries to argue, anyone with siblings knows that's the exact same thing as being related, and totally and utterly gross. Kurt is very religious and didn't know anything about this, so of course he's got to freak out about the fact that he was sleeping with his sister all this time.
Or he could ... celebrate. That's normal.
This isn't Wolverine or Gambit we're talking about here, who have somewhat loose morals when it comes to women. Nightcrawler is the most righteous overly religious character the team's ever had. Maybe mutants really do need to be eliminated from the Earth if this is the kind of low moral guidelines they live their lives by.
And just for the record, other than Colossus' brief look of surprise, no one else has any kind of problem with this at all, even when they both start talking about their mom, making it very clear that they still really think of each other as siblings. Kurt even considers his girlfriend/sister combo as some kind of sick birthday present to himself. But maybe we can give him the benefit of the doubt. Sure, he's been banging his sister, but that doesn't mean he's going to keep banging his sister, right? That would probably be going too far, especially for a hardcore Catholic like Kurt. This is going to be a strictly siblinglike relationship from now on.
Never mind. He's totally going to go fuck his sister later.

James Dao
James Dao is a deputy editor on the national desk of The New York Times, helping oversee coverage of veterans, health care, the Pacific Northwest, drug addiction, marijuana legalization, prisons, state finances and other issues.
He is also editor of The Times' military affairs blog, At War.
Between 2009 and 2013, he was a national correspondent covering military and veterans affairs, focusing on health care for combat veterans, the lives of deployed troops and military culture.
In 2010-11, he reported and wrote a series about an Army battalion's yearlong deployment to Afghanistan, "A Year at War," that received a 2011 Emmy, a 2012 Alfred I. DuPont-Columbia University award, as well as honors from the American Society of News Editors, the Association of Military Reporters and Editors, the National Press Photographers Association and Pictures of the Year International.
The following year, he produced a series of stories about the struggles of combat veterans to overcome the injuries of war, titled "The Hard Road Back."
Mr. Dao has been with The Times since 1992. Between 2006 and 2009, he was deputy metropolitan editor for three years, overseeing columnists and beat reporters. Before that he served as a national correspondent roving through the south and mid-Atlantic states. From 1998 until 2003, he was a Washington correspondent with stints covering Congress, the Pentagon, the State Department and the 2000 presidential campaign. During the invasion of Iraq in 2003, he embedded with Special Operations Forces in the Persian Gulf and Diwaniya Province, and has embedded with American forces in Afghanistan five times.
Prior to going to Washington, Mr. Dao was The Times's state house bureau chief in Albany, N.Y., where he covered two governors, Mario M. Cuomo and George E. Pataki.
Mr. Dao has also worked at the Daily News of New York, where his series profiling the changing neighborhoods of Queens was honored by by the American Planning Association. In 1990, he was principal writer on a year-long investigation into the smuggling of people from China to America, focusing on a criminal ring that was later responsible for the calamitous Golden Venture voyage.
Mr. Dao began his writing career at the New York Chinatown History Project, now known as the Museum of Chinese in American, where he raised funds, conducted oral histories, wrote radio scripts and developed programs about Chinese immigrants in America.
Born in Buffalo, N.Y., Mr. Dao received a B.A. in history, cum laude, from Yale College.

16 pages of people re-covering the same material over and over again...
I get the impression that people are talking about different things here. I think MrSparks is advocating server-side input sanitization whereas joeri is trying to argue the case against server-side HTML encoding. Different things but both relevant to XSS.
I fall into the camp that believes it is primarily the UI's responsibility to encode data to avoid HTML/JS-injection attacks but it would be wrong to suggest that the server can't help through input validation.
For example, imagine a username should only contain alphanumeric characters and that users can see each other's usernames. This is potentially a target for a script-injection attack. In this case the server (or DB) should be ensuring that all new users have valid alphanumeric usernames, thus removing any potential for them to contain script tags.
However, that is where the server's responsibility ends. It should not be HTML encoding data before including it in JSON responses. HTML encoding should be done in the UI and where possible it should be the default. Perhaps if all of your user-provided data is purely alphanumeric you can protect yourself just using server-side input sanitization but in the general case that doesn't apply. I'd argue it's naive to skip HTML encoding even in the alphanumeric case: relying on a distant part of the security layer to protect you is asking for trouble. All systems have security holes and not encoding is just another chink in the armour for hackers to exploit - many successful attacks rely on multiple small holes like this to get in.
Sencha have acknowledged that there's a problem here. There are a number of reasons why it hasn't been implemented yet: performance, increased code complexity, backwards compatibility, time investment required, availability of workarounds, ...ConsultJS: http://consultjs.com/
Skirtle's Den: http://skirtlesden.com/
22 Aug 2012 12:38 PM #162
Recommendation: Document where explicit HTML-encoding is required
Even if Sencha decides to continue treating user data as HTML, it is imperative that they at least document the locations in ExtJS where they do this. Otherwise, I cannot help but view ExtJS as a minefield of potential XSS holes and double-encoding surprises waiting to happen.
I was greatly aggravated to see Sencha representatives in this thread pooh-poohing the OP's complaint and berating other users for storing raw data in their databases. For now, and until Sencha takes encoding seriously, I am recommending that my colleagues avoid deploying ExtJS applications on public-facing dynamic sites.

I just want to weigh it and say that your argument above is only applicable per individual case. How did the user manage to get such an override in place? Having an override that decodes incoming data from the server is a separate subject and does not affect other users.
The server is more trusted as far as encoding/decoding data in my opinion because it protects attacks from reaching all users at once. Remember the pre web 2.0 era when everything was served remotely?
7 Oct 2012 2:33 PM #164
Okay, just read all pages and I'm just wondering how several stuff was mixed (skirtle already noted this) and other stuff is unavoidable or irrelevant.
So, just to clear some stuff.
#1 The application is a stack of modules
A frontend in a browser, a server backend and optionally a serverside database. And each module (layer) has some sub modules (sub layers).
Each layer (and even each sub layer) is responsible to archive it's security, validity and reliability of its own context. This includes everyones interfaces to the next layer but only in the context of call (let's say, the [browser] data request). Because of this, I don't need to check the user's credentials when performing a database write. Why on earth should someone do this? This is not the responsible layer for this (answer: Ask the security (sub) layer).
If the server backend writes data to the database, it won't care of stuff like HTML It will be (mostly) completely irrelevant. Everyone who admits that this would be easy, necassary or anything else just ignores that fact that in databases stored data are only... stored. It's okay for a mini website with only one way for now and forever, but not for a serios scalable environment. They can be used from other (http) endpoints, from other services. Let's talk about pdf. Too easy? PDF via XSLT (xslfo)? What about Mailing, what about Mailing with HTML mails?
The backend loads and writes data from and to the database. It MUST use a proper technique to avoid sql injections. And yes, not to use them is highly negligent . Just have a look into the latest security news. But that's it. Nothing more. Neither the request type nor the response type of content is relevant.
Additionally, the backend (in most cases a sub layer called "view") MUST encode the output correctly (likewise he does it decoding the request content). And that implicates that the (loaded) data could be encoded as well (regarding to @similian issue) no to break the output encoding/format. The encoding process is different between HTML and JSON.. even XML and HTML. Another point why encoded storage is a very bad idea. Content encoding is not part of the database layer. This would mean you would fixed the content type.
#2 Browser is the consumer / view
Why should someone care about HTML in a document which is actually JSON requested and therefor encoded? This is exactly what the browser in the most cases did.
In fact, the browser is only a (one?) consumer of data provided by a service located on the backend server. Let's say, you are using a simple API outputting JSON. If this API encodes implicitly the output how could we difference between a consumer for HTML (a browser) and a consumer for a desktop application (a native app). Both is JSON. The only encoding which matters if the transport itself (each string have to be encoded not to break JSON).
You get it? Encoding processing must be done where the view will be actually used.
A list of how to make applications better and scalable for further changes:
- Do not trust anyone on server side. Do really you think only your frontend could talk encoded with the server?
- Do not encode data on client side. This follows Rule #1: Do not trust the client. Because if you have to check if the content is already encoded (and you have to).. ehm that's weird.
- Do not decode encoded stuff or vice-versa. Following rules #1 and #2 give you always the option to add another output format, another service (PDF generator, mail reporting) or other hot stuff: Do you really want to escape the insane username of "<&>" in a tweet status call? Decoding already encoded stuff within your own application stack only proves that something is wrong.
- Encodings only where it is necessary. I think, anyone knows the time when the content is "&"--fied because the encoding had run amok. If the output is JSON, there won't be any HTML encoding required.
- If you want to get trusted HTML (i.e. a rich text editor in combination with a html rendered page like CMS) you have to validate the input. But in that case this is a special validation requirement "valid html with our constraints" of a special attribute of a concrete entity of your system. Even in a CMS this isn't default but a special case of a form value.
14 Oct 2012 3:29 AM #165
I haven't read the whole argument (sorry no time) but I don't see any point in trying to make front end more secure because a malicious user could as easily bypass it. Reminds me on how I cheated (some) of my faculty online exams because they never bothered to check time inconsistency on server side. For example: I had five minutes to complete the test. It had a java script timer and it was smart enough not to load the test if JS is disabled. However, a simple code extended my time to 24 hours. They could have made JS code to check for this but I would bypass it easily. The only way they could have caught me is to check time test was started and completed on server side, which they never did.

I do care about XSS and think it is better to have any possible measurements in place against XSS instead of only trusting that the server filters scripts for you. There is also a plenty of sources for XSS scripts - one of them of course the database content, but also content consumed from other APIs, HTTP headers, internal chat messages and so on...
Therefore I'm planning to have a global sanitising function for all strings, representing user input! Now I wonder what ocation would be the best in ExtJS from where I call this sanitising function. In models, readers & writers, fields?
Should I place event listeners that call a the sanitiser function on "beforerendering" fields (but then we miss grids and data views) or when we read data from a resource? I'd be thankful if you could share best practices and suggestions!
27 May 2013 11:29 PM #169
I'm not sure whether you mean sanitizing on input or sanitizing on output. You should sanitize input on the server.
Sanitizing on input is in my opinion not a good practice. Even the space character is dangerous in some places (e.g. in unquoted html attributes). I prefer to leave the input as-is (except for html which I run through htmlpurifier) and to encode context-aware for output per the OWASP XSS cheat sheet:
The challenge here is that rendering is context-specific. So, while htmlEncode will do fine in most cases, it is not sufficient in some others. You always have to be aware of the specific context you're rendering into. This makes it harder to encode properly for output.
28 May 2013 12:33 AM #170
Thanks for your answer. I already discovered this cheat sheet and htmlpurifier and was thinking about a similar strategy. Filtering INPUT on the server with htmlpurifier (Works only for text payload that could have malicious html or script tags???) and OUTPUT filtering in te UI. I understand that this has to happen context wise - just to be sure: When outputting text in a textfield or as the HTML of a container (CASE A), htmlEncode should be enough to catch malicious code or scripts. The part where I need to be carful is when I use OUTPUT parameters inside of HTML tags (CASE , for instance <img src=a onload="doEvil()" /> because here SPACES would matter.
Now I have some more questionsr egarding this:
1) What if I use input ExtJS fields, where I would use OUTPUT in the value parameter (checkbox {value: MALICIOUSCODE}). How would you address this?
2) I have plenty of UI parts where I display server OUTPUT. Wouldn't it be better to sanitize already at the level of receiving the OUTPUT from the server, means overwriting certain MODEL/READER methods to catch malicious code already at the point when I load it from an external resource? This way I need to sanitize once and not for every UI component.
3) The cheat sheet is quite long, did you implement checks for every mentioned case? Would you share your code? I would imagine this sanitizing is quite costful in processing time
4) How do you sanitize strings wthat are displayed in grids/trees?

We're heading into a brief break here at Loring Park, but before we go — an unexpected flood of canine appreciation, the catharsis of letting go and looking forward, and rising above difference to meet in Rumi's field.
For this Tuesday morning, a poem from Dena Simmons that might make you see things differently on your commute to work.
Forgiveness is not easily granted. But, summoning the deepest compassion for ourselves and others may allow both parties to move on without bitterness. Through the bittersweet story of her friend, Sharon Salzberg imparts a lesson about the shifting course of relationships and a path to peace.
At the age of 18, a young woman goes into a coma and faces a near-death experience. For nearly four years, she's hospitalized and tries to find peace and God — in a well-lit intensive care unit — in her dreams. A story of faith, hope, and gratitude for the landscape of dreams.
What gives our lives significance? In a small patch of wilderness, one man searches for meaning and finds sanctuaries for life for creation, and for what life could be.
As a society, we tend not to prioritize silence. When we take a moment to listen and to notice, we make space to be amazed. A meditation on silence, slowing down, and paying attention to allow us to be astonished and the people we want to be.
We spill something on ourselves, and then we postpone the inevitable: the cleaning. We often do the same thing with the pain and anger we inevitably experience. Omid and Rumi have something to say about stain-treating our hearts.
With the words of Rumi echoing loudly, Parker Palmer invites us to explore a "field" of sound ideas and right relationship with one another.
In this Letter from Loring Park, our executive editor lists three compelling reads under five minutes and some of our most popular columns. Enjoy the journey.
The task of the healthy is to be willing to see the same wholeness in those who aren't, to help them understand that they are needed and wanted and complete. A documentary film helps one man ponder how Jesus might frame our understanding of our potential role in modern-day healing.
Change is undeniable. Yet, we expend an immense amount of time and energy trying to alter this basic principle with rigid categorizations. This essay reminds us to embrace the dynamism before us.
Dogs and humans have lived alongside each other for thousands of years. Could it be that each species has impacted the evolution of the other? And could dogs be an essential element in human self-actualization?
With the near-constant news of extra-judicial police killings and mass shootings, it would be easy to live in a constant state of fear. Faced with his own fragile mortality, a Buddhist contemplates our collective fear and grief. For him, meditation is not about relaxation but about awakening to life — in its wonder and in its sorrow.
Rituals provide structure for the full spectrum of our emotional lives - but for those who don't identify with an organized religion, how are rituals developed? Courtney Martin ponders the "muddy, sacred" experience of creating rituals.
The prophetic voice is one that challenges, adapts, and evolves alongside history. Omid Safi reminds us of the sermon Dr. King never gave and invites us to live up to his hopeful invitation to create an America that is yet to be.
External "oughts" and "shoulds" can create impossibly high aspirations — and equally high levels of guilt about falling short. A personal exploration sharing the delicate experience of "befriending" depression and ways of reframing our expectations of self.
Compelling listening on trauma and resilience as it crosses generations, and the world around us.
When faced with the inner void, the fear of emptiness can tempt us to refill and restock as quickly as we can. Could an emptying clear the space to experience something else? Set against the background of opera, one woman's gorgeous account of truth breathed into the void.
So often we dwell on our mistakes. Sharon Salzberg helps us step away from this routine and walk a different terrain — with the practice of lovingkindness that develops a flexibility of looking at our own lives.
Spirit intersects matter everywhere. A poet living in Chesapeake Bay meditates on the sacredness of location and the sense of place reinstated after returning to her childhood landscape.
To "prioritize intention rather than form" is a the heart of a contemplative practice, whatever that may be. A lay Buddhist monk tells the story of creating a "tree" that's liberated us from narrow ideas of what contemplative practice is and find one (or more) that truly works for us.
We acquire and we accumulate. But why? What is the story we're trying to tell through the possessions we own. Our columnist Courtney Martin considers the multiple philosophies of ownership — and points toward that which is truly valuable.
Extraordinary images of Pluto reveal the vastness and mystery that lies beyond. Omid Safi revels in it all, weaving together the poetry of Rumi and Rabi'a with the "celestial realities mirrored in the human heart."
How might we summon "the better angels of our nature" as political shenanigans ensue? The ever-wise Parker Palmer offers a few suggestions (and a poem, of course!) to reclaim our commons — and our humanity — during this election season.
Words that shimmer, poetry to ponder, relationships to reexamine, prose that rivets, and photos that hide as much as they reveal — our executive editor's weekly missive.

Multiplication of matrices — taking the dot product of the $i$th row of the first matrix and the $j$th column of the second to yield the $ij$th entry of the product — is not a very intuitive operation: if you were to ask someone how to mutliply two matrices, he probably would not think of that method. Of course, it turns out to be very useful: matrix multiplication is precisely the operation that represents composition of transformations. But it's not intuitive. So my question is where it came from. Who thought of multiplying matrices in that way, and why? (Was it perhaps multiplication of a matrix and a vector first? If so, who thought of multiplying them in that way, and why?) My question is intact no matter whether matrix multiplication was done this way only after it was used as representation of composition of transformations, or whether, on the contrary, matrix multiplication came first. (Again, I'm not asking about the utility of multiplying matrices as we do: this is clear to me. I'm asking a question about history.)
Matrix multiplication is a symbolic way of substituting one linear change of variables into another one. If $x' = ax + by$ and $y' = cx+dy$, and $x'' = a'x' + b'y'$ and $y'' = c'x' + d'y'$ then we can plug the first pair of formulas into the second to express $x''$ and $y''$ in terms of $x$ and $y$: $$ x'' = a'x' + b'y' = a'(ax + by) + b'(cx+dy) = (a'a + b'c)x + (a'b + b'd)y $$ and $$ y'' = c'x' + d'y' = c'(ax+by) + d'(cx+dy) = (c'a+d'c)x + (c'b+d'd)y. $$ It can be tedious to keep writing the variables, so we use arrays to track the coefficients, with the formulas for $x'$ and $x''$ on the first row and for $y'$ and $y''$ on the second row. The above two linear substitutions coincide with the matrix product $$ \left( \begin{array}{cc} a'&b'\\c'&d' \end{array} \right) \left( \begin{array}{cc} a&b\\c&d \end{array} \right) = \left( \begin{array}{cc} a'a+b'c&a'b+b'd\\c'a+d'c&c'b+d'd \end{array} \right). $$ So matrix multiplication is just a bookkeeping device for systems of linear substitutions plugged into one another (order matters). The formulas are not intuitive, but it's nothing other than the simple idea of combining two linear changes of variables in succession.
Matrix multiplication was first defined explicitly in print by Cayley in 1858, in order to reflect the effect of composition of linear transformations. See paragraph 3 at http://darkwing.uoregon.edu/~vitulli/441.sp04/LinAlgHistory.html. However, the idea of tracking what happens to coefficients when one linear change of variables is substituted into another (which we view as matrix multiplication) goes back further. For instance, the work of number theorists in the early 19th century on binary quadratic forms $ax^2 + bxy + cy^2$ was full of linear changes of variables plugged into each other (especially linear changes of variable that we would recognize as coming from ${\rm SL}_2({\mathbf Z})$). For more on the background, see the paper by Thomas Hawkins on matrix theory in the 1974 ICM. Google "ICM 1974 Thomas Hawkins" and you'll find his paper among the top 3 hits.
Here is an answer directly reflecting the historical perspective from the paper Memoir on the theory of matrices By Authur Cayley, 1857. This paper is available here.
This paper is credited with "containing the first abstract definition of a matrix" and "a matrix algebra defining addition, multiplication, scalar multiplication and inverses" (source).
In this paper a nonstandard notation is used. I will do my best to place it in a more "modern" (but still nonstandard) notation. The bulk of the contents of this post will come from pages 20-21.
To introduce notation, $$ (X,Y,Z)= \left( \begin{array}{ccc} a & b & c \\ a' & b' & c' \\ a'' & b'' & c'' \end{array} \right)(x,y,z)$$
will represent the set of linear functions $(ax + by + cz, a'z + b'y + c'z, a''z + b''y + c''z)$ which are then called $(X,Y,Z)$.
Cayley defines addition and scalar multiplication and then moves to matrix multiplication or "composition". He specifically wants to deal with the issue of:
$$(X,Y,Z)= \left( \begin{array}{ccc} a & b & c \\ a' & b' & c' \\ a'' & b'' & c'' \end{array} \right)(x,y,z) \quad \text{where} \quad (x,y,z)= \left( \begin{array}{ccc} \alpha & \beta & \gamma \\ \alpha' & \beta' & \gamma' \\ \alpha'' & \beta'' & \gamma'' \\ \end{array} \right)(\xi,\eta,\zeta)$$
He now wants to represent $(X,Y,Z)$ in terms of $(\xi,\eta,\zeta)$. He does this by creating another matrix that satisfies the equation:
$$(X,Y,Z)= \left( \begin{array}{ccc} A & B & C \\ A' & B' & C' \\ A'' & B'' & C'' \\ \end{array} \right)(\xi,\eta,\zeta)$$
He continues to write that the value we obtain is:
$$\begin{align}\left( \begin{array}{ccc} A & B & C \\ A' & B' & C' \\ A'' & B'' & C'' \\ \end{array} \right) &= \left( \begin{array}{ccc} a & b & c \\ a' & b' & c' \\ a'' & b'' & c'' \end{array} \right)\left( \begin{array}{ccc} \alpha & \beta & \gamma \\ \alpha' & \beta' & \gamma' \\ \alpha'' & \beta'' & \gamma'' \\ \end{array} \right)\\[.25cm] &= \left( \begin{array}{ccc} a\alpha+b\alpha' + c\alpha'' & a\beta+b\beta' + c\beta'' & a\gamma+b\gamma' + c\gamma'' \\ a'\alpha+b'\alpha' + c'\alpha'' & a'\beta+b'\beta' + c'\beta'' & a'\gamma+b'\gamma' + c'\gamma'' \\ a''\alpha+b''\alpha' + c''\alpha'' & a''\beta+b''\beta' + c''\beta'' & a''\gamma+b''\gamma' + c''\gamma''\end{array} \right)\end{align}$$
This is the standard definition of matrix multiplication. I must believe that matrix multiplication was defined to deal with this specific problem. The paper continues to mention several properties of matrix multiplication such as non-commutativity, composition with unity and zero and exponentiation.
Here is the written rule of composition:
\begin{align} u & = 3x + 7y \\ v & = -2x + 11y \\ \\ \\ \\ p & =13u-20v \\ q & = 2u+6v \end{align} Given $x$ and $y$, how do you find $p$ and $q$? How do you wrote \begin{align} p & = \bullet x + \bullet y \\ q & = \bullet x+\bullet y\quad\text{?} \end{align} What numbers go where the four $\bullet$s are?
That's matrix multiplication. The rationale is mathematical, not historical.

I've been working a job for 2 years now as a SQL Server DBA for a city.
I was brought in to support an existing DBA, so I've slowly taken everything in and have been working for a while, trying to gain credibility in the organization. It's time to tackle the toughest and most important issue: security.
Our main server is a failover cluster with sql 2005 on it. It holds 166 databases. It serves 550 or so connections with app pooling for most applications, so it easily supports thousands of users. We also serve a public website that gets a fair amount of traffic. Vendor apps, in-house apps, access back-ends - quite a variety with a few critical applications.
Many developers have production access. Changes are being made outside the RFC process and we have no idea what data is being changed by developers. They also enjoy having production access during implementations of systems - which I'd also like to stop.
With so many applications running, any sane DBA would lock the server down.
How would you transition a team of developers from wide open security to a more restrictive environment?
I'm working on an emergency request system which will give them access to their database(s) for a limited time. This would give us auditing of access and ddl changes. Hopefully this will not be used - as it means we did not respond to a page. It will use HTTP, encrypted webconfig, login/pwd on screen(not email), request throttling to 3 per 12 hours. We would also be paged when a login is issued.
Any warnings about this type of system?
The major risk that I can see is that if a user's ntlogin were compromised - so would be their databases. We have that vulnerability right now since they always have access, but would never know if it happened.
edits: Development and staging are robust systems with 8 cores and 8GB memory. Planning on implementing a prd to stg copy mechanism that developers can operate if their db isn't massive and doesn't contain sensitive infos.
Management is supportive. If we can guarantee them access during emergencies, their biggest worry is taken care of. The other problem might be having access to production during implementations - which I'd rather not give. We can practice the move to staging first and test and fixes during the go-live there - with DBA's migrating to prd.

You might be getting a little frustrated by your size around now, which can make everyday activities more difficult. Simple maneuvers, such as fitting through doors or getting off the sofa, can be more difficult and you may find that everything takes a bit longer to achieve. All you can do is be patient and focus on getting through the next few weeks. You'll soon have your body back to normal.
During pregnancy, it's common to eat more often than previously but to eat less at each meal. This is because your uterus has grown so much that all your other organs have moved around and are squashed into much less space. Your stomach simply has less room in it to fit the food so you can't eat as much before feeling full. When your stomach empties you may find yourself hungry again. It's fine to snack, but make sure you're reaching for healthy foods and not the cookie jar!
Doctors used to think that if you had one baby by cesarean, all future babies must also be born that way. But doctors now know that 90 percent of women who delivered by cesarean are candidates for VBAC, or vaginal birth after caesarean. Depending on the reason for your prior cesarean, you may be able to deliver vaginally, especially if you have no major medical problems, the baby is healthy and in head-down position, of normal size, and any condition that necessitated your last cesarean isn't present. If you have diabetes, high blood pressure, or are pregnant with multiples, you are not a candidate for VBAC.
Your baby will usually move several times in the 20 to 30 minutes after you exercise. By keeping the intensity of your exercise at a moderate level you will not compromise the oxygen supply to your baby. When you exercise too hard and for too long, you may compromise this exchange and the result is the baby's movements will fall below their usual levels.
If you're concerned and unsure, keep a log of how much your baby is moving and compare this to the activity levels after exercise. If the level falls below what you consider to be "normal," speak to your doctor.

Concussions: Girls Have Longer Recovery Time
May 11, 2012 -- Girls take longer to recover from sports-related concussions than boys do, according to new research.
High school athletes, both boys and girls, also have longer recovery times than do college athletes, says researcher Tracey Covassin, PhD, associate professor of kinesiology and a certified athletic trainer at Michigan State University.
"We have known that high school kids will take longer," Covassin tells WebMD. "We are starting to show there are differences between female and male athletes."
Covassin's study evaluated 222 high school and college athletes who had sustained a concussion.
After a concussion, females also did worse than males on visual memory tests. They had more symptoms, Covassin found.
The study is published in The American Journal of Sports Medicine.
Concussion: The Problem
A concussion, a type of traumatic brain injury, results from an impact to the head. Those affected can have headaches, concentration problems, memory and balance problems, blurry vision, and nausea.
A concussion changes the way your brain functions, according to the CDC. It can occur even with a helmet on. Most do not involve loss of consciousness.
The injuries can lead to memory and communication problems, depression, and early dementia, the CDC says.
From 2001 through 2005, more than 150,000 sports-related concussions occurred in young people 14 to 19, Covassin says. However, the actual number is probably much higher, she says. The statistics only reflect concussions treated at an emergency department.
Awareness of the problem has grown in the wake of hundreds of lawsuits from former National Football League players. They are suing the NFL for what they claim are concussion-related dementia and other brain problems.
Concussion, Gender, and Age: Study Details
After the concussions, Covassin gave standard tests to measure thinking skills such as verbal and visual memory. She evaluated symptoms. She repeated the tests two, seven, and 14 days later.
She also tested the athletes' balance at one, two, and three days after the concussion.
The athletes played football, soccer, volleyball, basketball, wrestling, ice hockey, softball, rugby, crew, baseball, cheerleading, and lacrosse.
Among the findings:
- High school athletes did worse than college athletes on tests of verbal and visual memory (such as recalling a group of words just read).
- Girls and young women did worse than boys and young men on visual memory.
- Girls and young women had more symptoms than boys and young men.

STEUBENVILLE - Looking back, Rob Strobel says building upscale patio homes while the housing market was free-falling, world financial markets were crumbling and the national economy was in shambles was a little, well, risky. Some might even call it foolhardy.
"I knew we had a good product, but it was scary," concedes Strobel, contractor for Mission Pointe, an upscale patio home subdivision on Eldorado Drive in the Country Club Hills section of Steubenville. "The housing crunch hit when we were getting started, but we were already too far into it to back out."
So Strobel and his partners in GENPRO Development continued to build, but with a twist: Rather than tie their money up stockpiling a handful of completed units and then trying to market them, they opted to build as the orders came in.

MISSION POINTE PROGRESS — Contractor Rob Strobel says buyers looking to downsize from big, multi-story homes appreciate the easy-to-navigate floor plan and energy efficiency of the two- and three-bedroom patio homes in the Mission Pointe subdivision. Mission Pointe is a 28-unit subdivision in the Country Club Hills section of Steubenville, offering single-story living and a maintenance-free lifestyle. - Linda Harris
"The fact that we built them as we sold them kept us out of debt," said Strobel, president of GENPRO. "If we'd been sitting on six or seven of them, we'd have been in trouble. I'm glad the housing crunch started when it did, so we didn't overbuild."
Strobel, in fact, has finished 21 of the 28 units planned for the subdivision. He said they're averaging "five or six units a year now."
"In a big market that might not be all that impressive but in our market, that's good, actually, the economy is still slow," he said.
Strobel's two- and three-bedroom patio homes are about 1,500 square feet each and are set up for ease of navigation: One floor, no steps and an open floor plan, each with a good-sized master bedroom and oversized bath featuring double sinks and separate tub and shower. There's also a roomy walk-in closet, at least one other bedroom and a second full bath in every unit.
Each building has two distinct units. Priced at around $205,000 for a two-bedroom with no basement, all have 9-foot ceilings and an open concept kitchen/living area and a two-car garage. Some have a basement, most do not.
He said his buyers fancy the one-story living and maintenance-free lifestyle at Mission Pointe.
"Most of our customers are people moving out of big houses with stairs into one-level living," he said. While there's a monthly homeowner association fee, Strobel said it's modest - just a little more than $100 a month - and includes everything from mowing, landscaping and snow removal to exterior maintenance. Walls are thicker, offering better insulation, and that also translates into a savings on heating bills.
"The idea was to do all one floor with no steps, some with basements," he said. "They're all set up to be handicap-friendly."
And the fact that there aren't many places left in the community to build right now "kind of works to our advantage," he said, though he admits he's already thinking about the "what's next" scenario.
"I'm looking for our next development," said Strobel, who followed his recently retired father, Robert Strobel, and grandfather, the late Walter Strobel, into the construction business.
The Strobel family has a 65-year history in the building business.
"I don't know if it will be the same type of thing, or maybe something with shale oil. They're going to need places. I've talked to people (in the industry) who say it's coming. They thought it would be this year but it's not here yet. The demand hasn't come yet for the people we talked to."
But eventually, he said the jobs will come and with it, housing demand.
"I think there'll be a need for a lot of units, eventually," he said.
"And the people coming here will want nice places, not 30- or 40-year-old apartments. It's just hard to find land in Steubenville that's developable."
