Is it really idiomatic to use intrinsic truth values (eg, using "if x" instead of "if x != 0")? Here are my arguments against it: - "Explicit is better than implicit." - If there's need for a table as reference for what is intrinsically tru

In case anyone is wondering, Khan Academy did not launch today, as CrunchBase seems to think.

Well yeah, but the point is developers will start moving it out of the Documents folder.

I'm definitely at risk of running into this predicament as a user. I'm more worried about the hundreds of megabytes of podcasts I download when WiFi is available for use throughout the day when WiFi isn't available. To avoid this issue and

I really don't understand how "configuring a text editor" implies that "you don't understand that the only thing that matters in software is the experience of the user". Good user experiences can only be written if you haven't customized yo

I think the point is that a user wouldn't know they're overriding the design. When a user sets a uniform font, they're opting to not see whatever font the site was designed for, but it's not at all obvious to them that they'd be messing wit

The point isn't to sit and watch a 10-hour coding session. Even if such lengthy things are available, I imagine the most benefit would come from just watching a random 5 minutes of a bunch of different people's styles and learning from thei

I really like the menubar popover UI. What did you use to create that?

I found the conclusion at the end of the article, that e-readers as a platform are incapable of non-linear reading, a bit silly to be making about e-readers as a whole. These complaints are really issues of software, and UI specifically. Th

An environment which requires constantly lying to fit in dosen't sound like one anyone should want to be a part of.

Didn't realize this. Oh well. It's still cool and interesting, but I guess never that feasible.

Very cool idea. I don't know if I'll personally use it; as a dvorak user, it's harder to accidentally hit cmd-q when you mean it hit cmd-w. Then again, it's also easier to hit cmd-q some times because the q sits just above the cmd.

I've been meaning to follow along with the online collection of lectures from this course at some point, so I guess now's the time to actually dive in. I'm interested to see how a very rigorous course will be adapted to something that looks

The current model is that 20-30 kids who want to be moving around and interacting with each other are forced into seats and restricted from moving for hours while teachers talk at them until they get distracted and zone out the teacher to t

Improving education doesn't have the same immediate benefits, but the way I see it insufficient education is at the root of most of the world's problems. With improving education, you make a ripple which turns into a huge wave.

I'm almost frustrated to see this. I just learned to use urllib2, and found that it took a great deal of effort to get any reasonable behavior. I wish I had known about this before. It really looks great and I will try to use it in any futu

Not doing stupid shit is important, but what about not being afraid to make mistakes? Making mistakes is healthy and arguably one of the best ways to learn; if your motto is 'don't do stupid shit', then I fear that you'll miss out on a lot

Yeah, I don't see how Paul can say "usually it's not a problem" when it happens extremely frequently with every major press release.

It would be great to get more community involvement to help with these new exercises, but be aware that over the next week our main focus will be on getting the new framework and old exercises ported to the new framework ready to ship.

Seems like a great concept for a site. I (as well as many here) am looking forward to more comprehensive results on programming subjects.

Grammar girl has an explanation [1] of the rule I've heard elsewhere and always followed---splitting it into "Jack's and Jill's" if they have separate and distinct things (so "Jack's and Jill's stories") and attaching the possessive to the
