why do you say that ? Intel has nothing like Tegra (Clover Trail is not shipping yet) - which is already a GPU + CPU hybrid SOC. You dont need a separate CPU. Windows 8 is already running on Tegra 3 - http://www.anandtech.com/show/5614/microsoft-shows-windows-8...

Plus, the big big reason is that there is already a ton of content out there from big publishers that is Tegra optimized.

Tegra has been very successful in the thin client/ipad world and is looking to screw with Intel's server world with Project Denver.

I'm not even talking about nvidia's next gen Kepler graphics card released this week with serious power optimizations - Intel is seriously far away from that world.

In short, intel has 0 in graphics capabilities - while nvidia has 0.75 in cpu capabilities.
>The solution to working too much to be in touch with the partner you really care about is not an app, it's telling your boss to shove the job up his ass.

Agreed, but then there are those of us who formed solid, committed relationships before we had to or have to move and want to keep them alive. Even being on the other side of the same state from your fiancee is painful, man!

Fabric is more of a task-oriented SSH replacement with some really nice bells and whistles, much different from Puppet or Chef. Some folks are working on Salt Stack which is python-based and more akin to the others.
Of course, in "hot" data centers today the environment is no more dangerous than a nice sauna, but this development makes me imagine what it might progress to in 10 or 20 years. This is the first small step across that threshold between "comfortable for humans" and "comfortable for machines" in data centers, and the first such step is usually the hardest one. If it's more efficient to run the servers in an even hotter environment, or in one that's less-habitable in some other way, you can probably expect it to happen, now that the baseline technology and ideas are here.

Not that I'm trying to seriously forecast anything, or have any special knowledge of data center design; this is just a pleasant exercise in near-future sci-fi.
Years ago a data center outside DC in Silicon Alley had an A/C failure. Our equipment was reporting temps of 140F on intake. We were allowed 10 minutes in, one person doing work, another observer, both required to have squirt water bottles and a two-way radio. We were instructed not to carry anything and to use a cart. We were told not to remove equipment that weighed more than a few pounds.

I pulled 10 drives so we could run them to another data center as a 'just in case'. The guy I was with passed out about 60' from the door. The air temp outside was ~72F and they had portable hurricane fans blowing air into the data center.

In that ten minutes, I drank 32 ounces of water. I remember that because I went to pick him up, kicked my water bottle by accident and it fell over because it was empty.

He spent 30 minutes in an ambulance, about three hours in a hospital from 10 minutes exposure. It took me about two hours to recover to the point where I felt I could eat.

Don't lose respect for heat. :)
This was posted a while ago, and I have since implemented bitmaps myself. One thing I learned from the documentation[1] is that setting an initial bit at a very high-numbered place (like 2^30 - 1) takes a while to allocate (compared to Redis's normal speed) and blocks other operations in the process.

In my case, and it appears to be true for Spool too, I don't know what bit will be set first. It could be 12 or it could be 2938251, so to prevent a slowdown if the initial bit is a high place I use buckets of bitmaps, each holding around 8 million bits.

Writing outlines for projects
So I come from a writing background, and programming and writing have turned out to be very similar. I'm wondering how many of you write outlines for large projects, and how much time you spend on these outlines/how detailed these outlines are.

Do you write an outline in pseudocode, or an outline detailing the class/object relationships? Any insight or advice would be great.
Second that!

By what metric do you want to make such a comparison? I love both programs considering the reputation of both universities, certification would go a long way to get the foot in the door when it comes to jobs.

One aspect of this approach they don't mention is how it affects the MTBF of the equipment. Many components suffer increased failure rates when run at a consistently higher temperature. While it may be relatively safe to run machines in a range higher than is comfortable for humans, I bet there's an upper limit past which components really start to fail in numbers.
There are tons of reasons the job is rewarding, and many people who love it. People quit Google or Goldman Sachs for good reasons as well, just not the reasons I listed above.

You attacked his motives for quitting, and I think you were right, but there are also motives for quitting that can't be written publicly (unless you are willing to go Greg Smith).

A doctor can't write "I am dealing with a fatty with an asshole family and mismanaged diabetes thus now has renal failure and I have to deal with this shit" in a blog. It is a reason to quit being a hospitalist, but not something a person can blog. You can also quit Goldman because your co-workers call clients muppets. Some people love it, some people hate it. I am just not surprised.
It's amazing how many people either dismiss PowerShell out of hand because it's different, or don't even think about it when talking about Windows commandline support. Getting .NET objects returned, rather than piping text around is awesome. So is having an IDE specifically for writing PowerShell scripts. I'm still learning PowerShell, and love bash, but as powerful as bash is, in some ways it feels very primitive in comparison. If PowerShell 15 years old when bash was released, would anyone consider it better than PowerShell?
Drchrono is an emr. I could be wrong, but I think the author was thinking of a more focused solution for a specific problem.
The possibility of what malicious extensions could gain access to (credit card #s, passwords, bank accounts, email accounts), combined with the ease of installing and lack of suspicion users have with these extensions really scares me.

Does anyone know how actively moderated the Chrome Extensions store is?

I know recently Google made all developers use a credit card to verify names better, but this seems more of a reactive safety measure, i.e. after lots of people get hacked, Google can provide prosecutors with information.
If you're suggesting that other random free distros are suitable when one is looking at RHEL or an RHEL clone... well, that's rather silly.

Call it silly if you want, but yes, I would like to know the answer to that. I'm being perfectly serious. I've used several Linux distros (though maybe I'm not an expert), and at the end of the day, they all run the same programs.
It is definitely not moderated, I've had multiple plugins inject ads into my web browsing. One was a Facebook app to enlarge photos and it started adding these banners to the sides of facebook. I though it was Facebook using a new form of ads until I realized otherwise. I had another do it on yelp...
Why not just contribute the changes they need upstream where possible, and maintain a repo for additional "scientific" packages (or just fork and start new projects) when that strategy doesn't work?
So what's REE's solution and how does it differ from this approach?
The new await/async in C# 5 is beautiful. Just try/catch around an await and suddenly async is easy to read and handle errors.
The article mentions that "Studies by Intel and Microsoft showed that most servers do fine with higher temperatures and outside air, easing fears about higher hardware failure rates." So I think it isn't a big issue. Now, obviously there is going to be some upper limit, but it just hasn't been hit in this case.
A philosopher is someone smart enough to ask the hard questions and dumb enough to try to answer them.
I'd love to see your static generator — is it online anywhere?
The best part of this article is the troll who's a pedantic douche about how a coffee maker isn't an electronic gadget and battles everyone in the comment section. The best is the comment that's 2 columns wide because it's shifted so far to the right because the thread is so deep. I clicked like on it even though it's illegible. Someone else did too. I think you should too :-)
RHEL is extremely stable and releases are supported for much longer than other Linux distros. Also, some commercial software is designed to work on specific versions of RHEL.
I think this is great and having such high quality level instructors is very good. However, I'd caution the typical view nowadays, especially around here, that this signals the end of traditional college and that we should just throw it out.
I wrote mogade, which is a leaderboard/achievement/stats service. It's open source (https://github.com/mogade/mogade-server) and hosted. I don't know of anyone hosting their own; everyone uses mogade.com (maybe because it's free).

As you say, building something with the basic features of Parse is trivial. And, if you tailor it to your app, you can get a much cleaner API and better performance. I've wondered how parse will scale as long as it allows ad-hoc queries on unstructured data.

FWIW, I wrote the WP7 Parse library, just to get familiar with the service.

I'd be game for writing an open source implementation using ruby or node.js, I just wonder if there's really any market for that. It seems to me that if you want to go through the trouble of hosting it yourself, you'll spend the week or so to build your own. Otherwise, you'll use Parse.

Good point. Having to deal with portions of old code is better than not being able to use new features at all. I've revised my opinion.
Redis stores everything in RAM, and RAM is not as cheap as disk. Adding GB's of RAM every week will quickly get rather expensive. But I guess you could dump old data to disk and load it back to Redis only when you need it. It might even compress well, depending on what the metrics track.
For a long time it was common knowledge that computers last longer if you keep them cold. It's only been in the past few years that evidence has been shown that moderately high temperatures do not appreciably shorten equipment life.
Yes. You are spot on. I am not able to find readable survey-type articles other than the Wikipedia article on solipsism, but the idea you described is kind of folk-knowledge among really good philosophers of mind.

I think that is also why managers don't like off site employees.
Upper management might think a remote employee is the same as and outsourced Person.

Selling lottery tickets can be a losing proposition. In many states, the vendor has to pay for the whole roll as soon as tickets containing half the prize money have been sold. So if I have a roll of 500 tickets costing $5 each, and the first ticket is a $5000 winner and the rest of the tickets only cumulatively win $4999, then I have to pay for the entire roll even though I've only sold one ticket.
You know, I've always wondered why we couldn't just create our own elements as needed since we have CSS. I guess you'd have to ignore the semantics debate. But it would seem handy to be able to do <myelement> instead of <div class="myelement">.

Because Go builds statically linked executable files, the GVM tool only applies to development environments.

As far as the development environment is concerned, I find it easy to manage multiple versions of Go by setting $PATH and $GOPATH as needed. I only work with a couple of versions of Go at a time and I don't share packages between versions of Go, so my situation might be simpler than what they have at moovweb.

I expect that I will mostly use a single version of Go after Go 1 is released next week.
FYI, Python has an automated script for migrating code from Python 2.x to Python 3.x
Here is a paraphrase of what went wrong:

"The answer turned out to be 2 fold

1) We just got unlucky. In the Post-mortem analysis we figured out exactly what happened. And it was event that was very crucially timing related. The clock on the flight computer was slightly different than the clock the bench (ground) computer that all the tests had been run on. The probability that the sequence of events which led to the deadlock turned out to happen with a higher probability with the skewed clock.

2) How is it possible that the situation exists after the proof of correctness? One possibility is the proof system had a flaw. That turned out not to be the case. It turned out to be much more prosaic. Instead some assumption was wrong. Only the kernel of the system was proven to be deadlock free. However, the applications were not. And one application in particular had to work around some limitations with the kernel imposed programming model. That work around was the source of the deadlock since it was not analysed by the proof system.

"
I want to address the following quote from the article: "During the fall term, the Stanford students taking CS221 preferred watching the KnowLabs videos. Thrun says this improved their performance."

I took the official Stanford offering this past fall. I am not a Stanford student (anymore), but I enrolled as part of SCPD. As a result of the official course starting two weeks earlier than the public offering, the course staff usually didn't post up the YouTube videos in time for me to do the assignments, so I relied primarily on the lectures. (Actually, as a distance student, I relied upon the lecture recordings.)

I eventually did catch up on the YouTube videos, and I can attest that they are indeed better. However, they produced superior results mainly because they covered more material. For example, in one case, I did over two pages of error-prone calculations because I didn't know the mathematical shortcut that was taught in the YouTube videos. And I gasped as the professors spelled out in detail how to do problems that I had to think hard about how to do. Indeed, one problem that I was pleasantly challenged by on the midterm was simply not covered in lecture; in contrast, the professors explained it tutorial-style on YouTube.

Using the terminology of the course, I would say that the YouTube videos "overfitted" to the homework and exam problems -- so of course the students preferred the videos!

I do suspect that short, interactive, and extremely polished videos will be proven to be better in most cases, but unfortunately this experiment cannot be used as a basis for forming that conclusion. Clearly, the lectures were handicapped.

And to be honest, I am skeptical of how videos would perform against some of the tremendously excellent lectures out there, such as the introductory computer science lectures that are posted at Stanford Engineering Everywhere.

With all this said, I had a great deal of fun taking this course. I applaud the course staff for doing a stellar job, and I am grateful to be part of what I am certain will be a historical experiment.
Honestly, who hands out his/her Facebook password to an employer?!

This is like handing out private photo albums or access to the private email account. Any employer demanding this from me can happily continue to be an employer without me as employee (not that I have anything in my FB account anyway, but it's a matter of principle).
This makes me so happy to read. Honestly i love writing in c#. I spend a lot of my life now using php, but honestly the times when i followed best practices the best (unit tests all over the place, often test first approach) was when i was coding in c#. I think the language just lends itself, and the IDE...to doing things right.
I agree. I don't know about computer science students, but as a civil engineering student college means a whole lot more to me than just being lectured at. I'm involved in half a dozen student organizations, and a lot of the time I find myself learning more outside the classroom working with professors and other students on competition teams and organizations than I am in class. It's sad that so many people think watching videos can teach them as much as actually plugging into a real life program with other students and experience faculty to interact with. I think it shows there's something wrong with how most people are approaching college in general.
Does anybody know how to opt out of the new Groups UI?
agreed.. more info please... what kind of numbers can you make with this technique?
I like Python because I'm an inexperienced and infrequent programmer. While I took a few courses on programming (VB, Java), it wasn't til I discovered Python that I would actually code in my own time. All the boilerplate crap I had to deal with for Java was wiped away, and I could just write. I'm sure if I wrote more complex things, I could find better languages, but for simply getting things done and just jumping in and writing a few lines, Python just feels right.

Does that sound about right to those of you with more experience?
And keep pushing. Keep writing these letters. Keep not accepting things "because that's just the way it is". Keep getting the news out. Even if it takes 10 or 30 years.

It's worth it to provide real educations for the current youth of society. It means a future worth living in.
So, my $0.02. I have a CS degree from a small-ish state university in the midwest and, while I was quite a bit older at the time, I had the chance to observe lots students your age. Here is what I saw:

* The biggest indicator of success in the "real" world was simply drive and determination. Some left school early and have become very successful, one an engineer for Google and one a very successful game developer. Others went on to corporate programming jobs and are doing great. Others went to grad school at places like Carnegie Mellon and MIT, one doing _very_ cool research and another landing as a product manager at Google. What do they have in common, they work hard and are curious. Work hard and be curious.

* College is about much more than a technical/vocational education. Granted I learned amazingly useful CS concepts and gained technical skills. But I also had great classes like composition, public speaking, and matrix algebra. Those classes have easily helped me with my career as any technical class I ever took. Try to find a program with a balance.

* College is about a lot more than the education. Because of great professors I had the opportunity to do undergrad research and present it at conferences. Driving my own research and being the expert on it was an amazing feeling. Presenting it in front of peers was equally amazing. I also had opportunities to become a student leader, organizing events and groups. These are skills that are integral to being a good team member. Find outside opportunities.

So yeah, I was 34, not 18. And yeah, I don't work for Google or Facebook, but I work with damn smart people who constantly come up with awesome stuff.

I am not saying college is for everyone, but if you make the most of the opportunities, it opens amazing doors. You could easily apply the above points to starting your career early and there are plenty of amazing programmers who already have.

Either way, best of luck.
Not really excited. Sorry. To me this is an incremental improvement to a method of GC that is just not going to cut it.

Rubinius uses Generational GC. There are definitely some parts of Rubinius that are (currently) slower than MRI, but memory management stands to be one of places where Rubinius will demolish MRI in the long-run.

JRuby/JVM uses (from what I understand) a Generational-first hybrid GC. There's been so much work and analysis done on the JVM that there's no way in hell any mark and sweep GC is going to compete.

Honestly if MRI is going to remain competitive it needs to completely rethink the way it does GC.
