You can use a good number of these today with Retrolambda: https://github.com/orfjackal/retrolambda

Yes, the initial parts of the example could be accomplished with awk and xargs, but as the article goes on to demonstrate, even doing something like printing every nth element woul…

It looks like the TodoMVC[1] example has a bug: 1. Create an entry "foo" 2. Check the box, observe strikethrough on "foo" 3. Check the "check/uncheck all" box (left of input box) 4…

The videos are hosted on Dropbox. Dropbox disabled the videos because there has been too much public traffic.

True, but sometimes there isn't a choice, e.g., working with a clowntown library, poorly designed legacy code, etc.

I like to put a summarizing comment in the code for lines that require justification like the ones you mention. That way the discussion happens on GitHub and the conclusion is in t…

Best tweet: "Code so hard, VC's wanna find me"

Took me a second to find, but here's the all-on-one-page version: http://www.linuxprogrammingblog.com/all-about-linux-signals?...

Even in the movie 3 Idiots, at the end of the movie, the man with the pen points out that there's a reason for the complexity: bits of graphite flying around in zero gravity near i…

Why? While I have worked through a decent amount of CLRS myself, I think there are much better ways to learn how to solve algorithmic problems. For example, programming competition…

Regarding the Coffeescript-Javascript difference, Coffeescript and Javascript can be used transparently in node. Once require('coffee-script') is run, the module replaces the requi…

A fix to the halting problem? Jokes aside, timing out would be useful.

What are the consequences of running this in production? What's the performance hit like, is it unsafe, etc.?

For find, you need to use single quotes so your shell doesn't automatically expand the .java glob into the names of all the files. Also, find uses one dash for parameters, and can …

This is an interesting alternative to StackOverflow, though I think that you might be able to hit a wider and more skilled audience in an already established community.

This also works with live camera feed because of how OpenCV handles video streams. You can extract frames from the stream and then run the same face detection code on those extract…

I definitely agree; it's just a matter of finding the right people. Anecdote: attending some of the tech talks that companies give at Tech, there is always a gradient of people, fr…

No idea where this came from (or if it's a good idea to feed the trolls; "hn_is_dumb" - really?), but Tech does have the policy to accept most and then fail out those who don't bel…

This is the problem that I had when I was applying to colleges: I used to ignore classes that bored me but were required and instead spent time that should have been spent on homew…
