I'm basing it on both my time as a math tutor for Pima Community College and on people I have known.

People like my mother who, if she can quantify the data she can effectively do algebra, but as soon as X and Y appear she shuts down. She cannot make the jump to the abstract thinking of math, and it curtailed her ability to go back to college. It didn't help that her math teacher in 9th grade told her that she would never be good at math, much like many women from poor backgrounds. (I have no study, only the experience in tutoring on how many women said that a teacher told them not to bother, and could never make it over that hump.) Now you say that it's merely psychological for them and that they could. I'm telling you that for as much work as some of these people I tutored put in, they had a mental block that they simply could not overcome, fighting their way to a C in college algebra so they could get to where they're going.

I can give as an example my boyfriend, who can speak and teach two languages better than most people here can in their native language, and is a promising Ph.D candidate in his program. He worked for a month straight (with my help) to raise his GRE math to a minimum score. His limit may be calculus, but certainly not higher math, and not upper level sciences. Yet I have seen this man wake up, read, write, sleep, and repeat for weeks straight.

He's a gifted writer and academic, but even if he could muddle through (say...) managed information systems, he'd never be more than mediocre because his brain simply does not work that way. (He still asks for help with his Mac.) Square peg, round hole.

It doesn't benefit those who have a passion for the sciences to put him and dozens of others in the same class, wearing down the professor because they struggle to grasp concepts that future scientists understood in fifth grade.

I'm working on something like this for the next evolution of the entropy visualizations. I've toyed with compression, but have had nicer results so far with other randomness estimators. I'll do a writeup once I have something to show.

For a continuous compression function your idea of running on a rotated or reversed version of the file and then taking a minimum is a cunning one! Right now, I'm still working with sliding windows, but I'll keep it in mind if I turn back to compression.
I think open sourcing this wouldnt take long. Basically a transaction-al email is sent based on data in a user system. The fact that the patent is for email communication that contains a "notification containing a portion of a da out of office notice. " ... is just ... ridiculous.
If this happens, does this mean that manufacturers or vendors will have to practically give away computers? They're already so cheap that even the slightest tech-savvy consumer will just go ahead and pay a tiny, small premium for the ability to do whatever.
NC Senator Advisor meeting advice : SOPA
That was a huge mistake for me when first learning vim. If you start with someone else's .vimrc, you will run into a lot more "FML, what is going on" experiences that you should.
"I already run my own UnrealIRC daemon, on Linode, for $20/mo with however many users it can handle."

Then I would argue you're not the target market. I'm a tech company CEO. I have WAY better things to do than set up an IRC server, even though my background is Linux system administration. My employees (we have 8 people currently; hiring #9) also have better things to do (like, you know, features our customers want :)

So we use Hipchat. And Hipchat rocks. Everyone on our team loves it. (We actually tried grove first, but it just wasn't mature enough for our needs--Hipchat has Mac OS, Windows, web, Android, AND iPhone apps, and we're all on different platforms, so that works out well.)

When you're paying developers $$$, you don't want them to be setting up IRC servers. Better to use a Hipchat or a Grove.io and be up and running in 5 minutes with clients on every device. For us, it's well worth the few $ a month to have one less thing to set up and maintain.
Does anyone know if this was the 'official' Twitter Android app? If so, that is pretty bad.
Cheers. :) I'm trying very, very hard to resist the urge to start writing a binary dissection tool based on this. I'm picturing a hex viewer with a space-filling curve navigation pane, with options to switch between different pixel layouts, and color maps. Then again, the last thing I need is another side-project.
Well, among other things you burn less energy to get the goods to your doorstep.
You're right that memoization is a subset of caching but it still warrants special attention because every pure function gets to have a .Memoize() "method" for free. This isn't true for caching in general.

Kind-of a long-winded way to point out the (very well known) fact that passing non-terminated strings to functions that expect terminated strings is fraught with danger, isn't it?
I'd go as far as to add a "Why should we give this to you?" question, because honestly, why should IBM get a patent over this?
While putting up an interstitial to warn about SOPA/PIPA and get people to call their representatives would be almost as effective in its short term impact on those 2 bills, I think completely blacking out is a much more effective long term strategy.

The chance that politicians would try something like SOPA/PIPA anytime soon, if all major sites go dark in that day, is much smaller. Showing an interstitial could be a form of protest against anything. Going dark is clearly a form of protest against censorship. And I don't think any politician will want to be associated with that in the future.

I would also be interested in how this could work. I've tried setting up VLC as a video phone, but the lag time was horrendous and that was when calling localhost.
If I where doing a Desktop Java app, I think I would take the time to learn JavaFX. While I don't think we will see widespread adoption, I do think most people will favor it over swing. I did a simple app in it and I prefer it to swing. Take my advise with a grain of salt though, I have not been deep in desktop for a long time. It was a fluke that I had a Java desktop app contract.
Wow this comment thread is depressing.

Anyone who can't see the exploitation in this has their head in the sand.

If you are paying/treating people less (in value) than what they contribute (in value) back to you, you are exploiting them. Simple as that.

Apple have taken to boasting how great their profit margins are, another way to look at that, is to say they are boasting at how well they can exploit others (suppliers and consumers).

Seriously, stop rationalising that your iDevice/Android is a moral device, it isn't in a utilitarian, or deontological sense, by any stretch.
Only some weak relativistic point of view can justify it. But that's what helps people sleep at night, so we all just hover around there.
An honest mistake...no worries, just leave it.
Surprising - given you already had a self-hosted IRC server, switching to Grove seems like an expensive option for more or less just the addition of logging features?
You have to work with the 'who' to actually get anywhere with some of this stuff. And some of these communities are less than friendly. Some of them are outright hostile.

Does that help?
Best way to get it made in the UK would seem to be to buy one and support the movement so that they can continue pressuring the government to allow them to make them in the UK.

I mean really, who are you protesting against? The government, right? What does the government care if you don't buy a $25 gadget?

I agree that a long term strategy for improving working conditions involves access to quality education but I don't think that pertains to the issue being discussed nor is it very helpful to the people described in the article. The sad fact is these people are living their lives now and have virtually no bargaining power now. So they've taken to following the example set by the desperate measures of their former co-workers as a last ditch effort to eek out a fight. Perhaps the mass suicide was dis-genuine and they just wanted media attention. This to me is an indicator of what they feel they have to do to get a semblance of justice. Or that they genuinely have no idea how to stand up to their employer. An employer, mind you, that requires them to sign a contract stating that they will not commit suicide on the job. Think about that. Where would you be if you got paid $2 an hour to stand on your feet for 12 hours a day working with toxic chemicals without proper safety measures, having had signed a contract stating you wouldn't commit suicide, with no legal right to organize coworkers to even discuss how to improve working conditions, and don't have enough education to understand any of it other than your legs hurt, your hands won't stop shaking, and you haven't yet received any money for that overtime you put in to make electronics you'll never see people in your own country using.

Very sad.

I think this should be seen as a case for why robotic automation should be encouraged wherever and whenever possible. There tends to be an undertone of fear when we talk about automation - fear that robots and technology are going to eliminate everyone's job. Lets also consider that certain jobs out there are not suitable or healthy for breathing, thinking, creative, unique humans (which we all are) to be doing.
Really?
Did he really expect wordpress would ship those specific features out of the box? Come on. That is not even a mater of feature richness, it's simply keeping it bloat free to some extent.

I can agree with him on things like lack of a fancy wysiwyg, but workflows? Multi side admin? Pay someone to implement that for you if you don't want to do it yourself.

There are more important issues with wordpres that should be solved: built in support for syntax highlight, a fancier javascript image gallery browser, etc.
A simpler more effective plugin system (current one is an unmitigated mess).
Others cool stuff have been added lately such as drag and drop uploads.

This guy is expecting to have someone coding a custom software for him just because it's available with GPL license. Non-sense.
Wow, couldn't disagree more. "Ask for paper" may be the single most pragmatic and useful interview tip I've ever gotten on this site. I grinned ear-to-ear when I realized that was the point he was making.

The Project Euler stuff I could go either way on, but I thought this was such a great post.

Well, outsourcing to China is probably "charity".

Think about it. If people are working there accept such low wages, they probably don't have other options. The alternative is, lower wages?
hey thanks for the article to andesbeat,

I saw a comment (was deleted?) asking on how to implement on games based on C, well since we used socket.io you would just have to listen at the same port and code the game according to the commands that are being send, for instance "move_down", "move_up", "fire" etc.
Choosing the Best Forex Broker is the First Step in Your Forex Trading
I call balogna; it probably takes longer to go through the purchase / registration process for a service like this than it does to fire up your own IRC server on one of your available boxes.
Upvoted - didn't know that. Is it significantly different?
Not from Bocoup, and can't speak for Rails, but Django mostly does not care about that.

I started using Brunch with Django recently, by simply putting it (sans bundled index.html) into `$PROJECT/client-side` directory and specifying the build folder as a primary static files directory. Then I run `brunch watch` in parallel with development server. The same could be done with boilerplate, it seems.

If you know the available packages. And get really lucky.

For most people who haven't done it much before, will have to do some research first, and probably end up shaving yaks for a bit.

Grove (I'm honored, by the way) seems like a nice middleground. Make the busy founders happy (easy, no maintenance), make the devs happy (irc).

Why SOPA-Supporting News Networks Don’t Mention SOPA At All
or the real issue: how can we convince people that freedom is more important than defence, so that bullshit arguments like "interfering with the ability to fight terrorism" can't be used in the future to restrict basic rights like freedom of speech?
Will Motorola spur a $12.5 billion loss for Google?
reddit is kind of preaching to the choir here, but reddit is a big site and hopefully this move will help convince other big sites that they should join in the blackout.
I couldn't find anything related to anorexia or eating disorders in the story. It is frugal, perhaps, but not anorexic.

What a misleading title.
Yes, they most certainly do throw off the timer. This was the main reason I stopped using sleepcycle. A wrist-strap certainly seems like a better option.
Every week there's some post like this, or "why I switched back and forth between Vim and Textmate 17 times", and, frankly, I just don't see the merit in it. Are you trying to get other people to use the editor you like?
It's surprising how often chat services get compared to Yammer which has no IM functionality.
What kind of patent is novel, non obvious and useful, but should not be patentable?
The function copy expects a C style string but he pass a buffer to some data. If you pass it the proper argument you'll get a proper result, it's that simple.

I see the complaint is more about C style strings in general because it's easy to corrupt them by overwriting NULL at the end rather than a complaint about "K&R C" book. I don't get why he decided to put it under this title.
Styling Button Links With CSS3
Which actually is somewhat strange, as one might upvote the story only to realize at later examination that it's less fine as one originally thought. And taking back votes isn't allowed, or requires some karma.
1. Would donations be tax-exempt?

2. Would these people be entitled to privacy when they perform their religious activities?

3. Would they be able to block courts the publication of their secret rites?

4. Would they be allowed to freely express their religious views, and live their holy life?
"When you're paying developers $$$, you don't want them to be setting up IRC servers."

Fair enough but still if it takes 1 hour to set it up vs paying 50$*12. (But I get your point, that's why I said I found it a bit risky in another post.. that's the developers mentality vs the CEO's one.)
I believe it is open... just not Free.
Simple and clean interface, however, I couldn't find the checkbox for "h1b". Any thoughts to open source the project?
Interesting the other cofounders moved to create Boilerplate, a company focused on building apps, now to creating clutch.io, a development framework for apps. So combined between the founders a lot of pivoting.

Also interesting the quote about needing over a million users to really create any real profit through ads. Lots of free consumer apps seem to end up with user counts that seem really big but are probably still hard to profit with.
Both goals are to improve communication for a team.

Right, but money has a way of figuring out 1 and 2.

Seriously, if they get awarded this patent, I'm just going to go through everything I can think of and file patents for half. Apple patents "swipe", I'll patent the "half swipe". Microsoft patents "avoid Ghetto" GPS feature, I'll patent the "avoid areas near a Walmart" feature.
What do you think that SOPA is/does?
That's not "new", anymore -- SFR and Orange do the same as well now.

But yes, it's a great idea. As the owner of the set-top box, you're allowed to configure it to disable that, but virtually no one does -- because the usage from outside is always fairly minimal (but when you're traveling it can really come in handy).
Mine is Qt.

I am developing an admin client for PostgreSQL: pgXplorer (github.com/davyjones/pgXplorer). I was coding primary on a Windows platform and decided at some point that a Linux build would be useful as well. I was surprised when the project compiled the first time I imported it into my Linux environment, and that too without any tweaks. So yeah...more than surprised actually.

But...there are some issues I am facing with window behaviour, mouse events, etc. Still working on that.
When it comes to the social stigma of taking a nap at work, just ask if they'd prefer you take a smoke break every hour. Usually, people will get the hint. If not, too bad.
Adidas Men's Thrasher Tr M Running Shoe
I have not tried this, but have read about this technique: When you start your nap, hold something in your hand that will make a noise if you drop it. As your body relaxes and you start to sleep, you will eventually relax your grip enough that the object will fall to the floor and wake you up. This happens at just about the ideal wake time for a short power nap.
Skype works pretty well for small teams too. One advantage is you can bring customers into the chat seamlessly if they already have a skype account.

Well, when I started using Emacs, I copied a lot of snippets of code which I didn't understand, and it didn't hamper my learning process. Quite the contrary, it sped it up because I was able to override some annoying behaviors before learning how to do it.

Come on folks, Wordpress is a CMS. It manages content, and has more features than half the other CMSs. At this point the blogging setup that comes by default is just built on top of general abstractions.

I've used it for plenty of projects, and IMO there are two things holding it back: the violent release cycle (frequent UI changes, out-of-date plugins, mandatory major upgrades) and the shitty performance (a standard install gets barely a single request/second on a common shared box, for a content-rich page - file based caching doesn't help much).

On the other side it's the most flexible, easy to customize and pleasant to use CMS out there. It's a shame, really.
That's not a distinguishing feature (HipChat works in Adium too)
I would write it as follows. Same argument.

if (max > 0) printf("%s",longest);
