I disagree. A "real programmer" should know something about how the computer works, and should not revere anything below his level as "magic" or be afraid of it, even if he/she will never need to deal with it. Understanding that integers

Yes. Microsoft asked me to verbally test my code (come up with a few examples and walk through the code), and Google asked me to describe a range of test cases to start with, and to decide if my code passed them. They want to know that you

Did anyone else think "don't you just check if it's on the positive real axis?"

Re: 8, you don't need decorators to compose functions: def comp(f, g): def h(*args, **kwargs): return g(f(*args, **kwargs)) # fix up h.__doc__ and friends return h or simply (lambda the, ar

At a good university, with the intent of putting in lots of extra effort on your own and going beyond the scope of the classes. I contest that the vast majority cannot program effectively without the foundation you get at a university, no

At a university. I can't tell you how sick I am of laypeople thinking they can just pick up one or two programming languages in a couple hours a week and get a job. These people end up with a very small skillset and no knowledge of what

No, I'm not opposed to references being modified by functions, I'm opposed to the "ampersand" syntax of C++. I am fully in support of just passing a pointer and being straightforward about it.

This actually bothered me to no end at google. At the API level, it's great, I can learn a lot about what your function is going to do just by looking at the signature, but when reading code that uses an API I don't know, it's hell. For m

They aren't, but it would be nice to see all his opinions laid out at once so I could absorb the good ones.

Yeah, I didn't mean "int" to be the offensive part. Read my response. I'm not talking about performance, you shouldn't be copying around large structs or strings no matter what, I'm talking about code readability. In general, your compiler

Because it gives you no more power than passing a pointer. If you're handling pointers, it's better to be totally explicit about what you're doing. I don't want to read your function call that looks like it passes a whole object and have t

you also probably don't want to memoize, you aren't going to re-use, so why waste the memory?

I can't read ruby, but here's something a little smarter than brute force in C (on its way to DP, but I couldn't be arsed to work out the recurrence so I just iterated until it stabilized): http://gist.github.com/617854

No, the OP is talking about encrypting the data (the mail), not the credentials (the password). EDIT: oh, you caught on

Because we've already got pgp, and when we can get the people we communicate with to use it, we don't mind using a command-line program (or a browser plugin, though we don't even really trust that) to decrypt. We definitely wouldn't trust

The "dead field" you speak of is deterministic A.I. research. Statistical methods (read: machine learning) are doing extremely well these days, and only get more powerful the more data we get our hands on.

An isomorphism requires a metric, which metric do you mean? I'm talking group homomorphic, though they're also topologically isomorphic, a.k.a. homeomorphic.

Only once did I see emacs malloc all of my ram, but it did it on the server and crashed it. No clue what happened, but I barely got top open to see it happen before the kernel panicked. A once-in-a-lifetime experience though, I start the e

I learned linear algebra from axler and real analysis from bartle and sherbert too. :) Great books.
