I highly recommend Head First Java, which focuses on OOP using Java. The entire Head First series is very well written, and focuses on practical learning rather than reference or academia as a lot of the suggestions do.

After a depressingly latent period of non-doing in 2009, I broke out of my shell and kicked some ass in 2010. May and after was the period of "getting shit done" as I kicked in to full throttle and overcame my fear of not-wanting-to-code-a

If you're in San Fran, I cannot recommend looking into this company highly enough. I interviewed with them and was thoroughly impressed, and would have taken the job but chickened out on moving away from NYC. That's good news for you. Do

To dodge the question: I don't often find creativity to be the bottleneck of my output. Execution is what takes time. To answer the question: Probably beliefs that act as rules. It's written somewhere in a PG essay that it's best to not

I'm far from an expert on the topic, but couldn't convertible debt be an option?

I should have noted that "foo" wasn't meant to be taken literally; clearly it should be something that wouldn't show up in a dictionary. Even so, the point was that any salt is substantially better than none, and is easy to implement.

Thanks for sharing. Have you subscribed to any strategies?

This might be only tangentially related, and I'm sure nearly everyone on HN knows this, but salting MD5's is probably the easiest way to significantly increase their security. By changing md5($var) to md5($var . "foo") this type of attack

To me, I find it more limiting that child comments are not nested within their parents. For example, implementing a show/hide children feature is annoyingly difficult to do, as is showing trails leading to the parent. IIRC, all HN comments

Technically, photons always travel at c. Slow moving light is caused by the medium continually absorbing, delaying, then re-emitting the photon, or by other stuff which I won't pretend to understand [1]. Either way, rest assured that elec

You don't need math skills to solve this, only problem solving skills. There are only so many ways to systematically choose 50 boxes from 100 when the only information is a name on the inside and a number on the outside.

Assume the prisoners do not have access to the internet.
105.
by photon_off 16y ago
Correct, and after each prisoner goes, the boxes are restored to their original state.
106.
by photon_off 16y ago
The boxes' states are restored after each prisoner leaves the room, so there's no way to sort them. The ideal solution would actually work even if the order of the boxes was shuffled each time.

I know this one too, and I'm pretty sure a set of problems containing this one was posted on hn a long while back. I suggest using the constraints of the problem to your advantage. There's only a limited number of ways one could choose b

I see what you mean. Prisoner 1 could memorize all of the names and just tell the next one if he's in the front or back 50. The catch is: once the prisoners decide on a strategy, they are not permitted to communicate anymore.

There are two things to know. 'aa' < 'z' , which I think is expected. And 'z'+1 == 'aa', which is debatable, but not far-fetched. As far language blunders go, I don't see this as unforgivable, especially since it only appears when you

That sounds like an impossibly huge fireball for a rocket. IIRC even nukes don't create fireballs that large. Maybe I'm underestimating the amount of energy in a rocket. My guess is that the main threat would be an off course rocket, or de

While you're at it, you might want to consider having the ReeVoo logo on the bottom left link to ReeVoo.com.

Please explain: what makes this choice "correct?" Is it because it's your personal preference? Different languages have different features. I've been coding PHP for years, and I've never encountered this feature before. I suspect that's

by photon_off 16y ago
Perl does this, too. And is it really that unexpected? How many possible things could 'z'+1 return? The only possibilities that make sense to me are "{", "aa", or an error. I like PHP because it's flexible, and this often makes life eas

It's always the fastest, but whether or not it's the fairest depends on how you define "fair." The simplest example I can use to illustrate this is the case where there is 1 server, and 2 people. One person will take 60 minutes to proce

I would pay up to $100 for a website that had me take tests to prove that I'm not a crappy developer, and that had a reputation for uniting programming talent with awesome companies. I really wish something like this would exist, as I'm ge

I didn't apply this time around, for several reasons which aren't really important. Otherwise, I'd have definitely included it... you know, to show others how it's done.

This is a really stellar example, and I'll definitely use this as inspiration. Thanks for sharing it.

Great advice. Also great: "One time I found an olive underneath the couch and Jeff was like, "Dude! That's disgusting!". He shamed me into not eating that olive and he might have possibly saved my life."
