That post was one of the things that inspired me to start tinkering with gdb. Very cool stuff.

This describes my experience being in batch[0]. I came in with relatively little professional programming experience, but lots of energy. In addition to learning a ton and meeting some great friends, I also got a great job at Venmo right

I was in batch[0], and would say yes. If you can swing the time off, Hackerschool would be an incredible experience. Nick, Dave, and Sonali are some of the nicest people I've ever met--they were born to do this. They attract similarly aweso

I'm also in the interested-onlooker camp, but I think this is an example of a variable denoting a computation rather than a value. It's a Haskell version of an exercise in SICP: > p = p > if True then "I'm the value of this expressi

I was a physics major in college and got into programming a couple years ago. In my experience, of the hard sciences, CS is by far the most amenable to self-study. CS isn't easier, whatever that might mean, but CS is amazingly inviting: i

No. The (sqr * inc) part returns a lambda, and in order to call a lambda you need to either .call() it, or you can use the [] syntax.

He was in the Society of Fellows at Harvard, and is an extremely prolific, opinionated blogger. He and Peter Woit over at Not Even Wrong used to feud constantly. Interestingly, Motl is actually really polite and charming in a shy, goofy way

It definitely helps to have a good athletic background, but Crossfit does an amazing job of welcoming beginners. Honestly, I can't think of any other community that does such a good job of simultaneously pushing the most advanced to their l

I tell practically everyone I know to try Crossfit. There are two basic difficulties with any exercise regimen, and Crossfit nails both: 1. Figuring out what to do. 2. Actually doing it, consistently, over the long haul. Crossfit will teach

I'm not really sure what to make of reports like this. One the one hand, it does seem pretty terrifying. But on the other, I feel like the fact that the governing apparatus of the US has more-or-less worked for several hundred years can't h

Along those lines, I think that Rubyists would really benefit from a "Fundamentals of Unix for Rubyists" book (well, not just Rubyists, but you know what I mean). I'm thinking a book at the same level as The Well-Grounded Rubyist--essential

Nick, I'm reading two really cool books that you might enjoy when you're in a "bottom-up" phase: The Elements of Computing Systems [0] and Computer Systems: A Programmer's Perspective [1] [0] http://www1.idc.ac.il/tecs/ [1] http://csapp.

If I start reading something non-technical, I quickly slip back into "hearing" mode (maybe 500 wpm), but I've gotten worse at this over time as I've started spending more and more time with technical material.

Informal poll: how fast do you read, in pages/min? Assume typical fiction paperback pages. My girlfriend is an extremely fast reader, somewhere around 3 pages/min. E.g. she just read A Game of Thrones in a couple days. I'm not a slow reader

I guess it depends on what the original point was--I took narrator's point to be that certain people have bigger chess smarts than others, where smarts is something that you're blessed with at birth. I may have read too much into that. And

Thank you for posting those. I'll take a more careful look tomorrow morning, but my quick perusal of the Kenschaft article has been sobering :(

I also really like the simple-but-awesome tricks for multiplications: 1) (a + b) (a + c) = a (a + b + c) + b c. Example: 13 14 = 10 * (13 + 4) + 3 4. You learn to "see" 13 14 --> 170 + 12 = 182. 2) (a + b) (x a + c) = a (x a + c + x

Metaprogramming Ruby [0] explains Ruby's handling of scope really well. Also, you might enjoy a silly gem I wrote a while ago called ghost_attributes [1]. It uses closures to mimic attr_accessor. The funny thing about it is that your ghost

Nice article :) The thing that helped me understand closures was really thinking about why they're confusing for beginners. For example, let's say you show the following code to someone who's never heard of closures, and ask them what it

Yeah, then I think you're better off relentlessly building things. You'll have plenty of opportunities to learn CS incrementally as you go. Personally, I know that I have a pretty extreme bias towards wanting to "study forever", which is re
