cjzhang··on Carsabi Opens Access To Car Data (Apparently Green Cars Are Cheaper?)
Is it possible to get a view that shows average price AND the number of samples (maybe if you mouse over a column) at the same time? Or maybe some info about stuff like variance, stdev, median, etc?

Trying to figure out why green cars are cheaper:

It looks like green cars are mostly from 97 to 2003 in a roughly normal curve, while most other colors are exponential (so mostly from the last couple years instead, and dropping off dramatically once you reach 2005 and older). Not counting purple, which has 8 samples and is therefore mostly useless, hah.

cjzhang··on Hacking the Used Car Purchase
But what about the time investment needed in finding an acceptable car on Craigslist compared to finding one from a dealer?

If you're spending something like 100 bucks and 20 extra hours over three weeks checking out N more cars that don't pan out because {the guy lied about the condition of the car, the guy selling it is really sketchy, other random reasons}, then is it still worth it to save an extra 1-2k?

What I'm trying to ask basically is "but what kind of opportunity costs are involved in these hacks, and when does it stop being viable"?

cjzhang··on Dare HN: Download/purchase True Blood without BitTorrent or subscribing to HBO
If not, maybe it's time for a web-based BitTorrent of some kind. The important thing is that file sharing would go back to being a download-only operation which would (ideally) free fans from the threat of disconnects and lawsuits. This is all well beyond anything I could ever do, which is why I ask about it here. To me, this is the inevitable future of the web.

Don't take this the wrong way but, are you trolling?

EDIT: Also, Mad Men's on Netflix streaming, off the top of my head.

But no, seriously, you should be using a library or something that sanitizes your SQL queries for you. If you aren't constructing the query string yourself, you should be okay.

This doesn't seem to be through the main humble bundle site. Are you reselling the bundles or something?

Really?

cjzhang··on What happened to all the female developers?
I personally feel that women get turned off to CS and in general tech courses because they're male-dominated and usually somewhat misogynistic, which makes being in CS classes and interacting with CS majors sometimes unpleasant and encourages them to do something else.

In general, women are perfectly intelligent and capable of studying (see: women in premed, women in law, etc, etc).

CS isn't some mystical major that's harder than every other major ever (me, I'm scared of business majors; those guys are cutthroat), and I don't think "women can't commit themselves and women can't study the same way and women don't do research" is really a good explanation for why there are fewer women in CS than there are in premed.

cjzhang··on What happened to all the female developers?
Why didn't you just say "women can't code?"

Also, the sample size is crap and the deviation is crap relative to the sample size, so you can't make very many truly meaningful observations from it.

cjzhang··on The Brilliance of Dwarf Fortress
It's actually not that hard to get the basics if you're used to ASCII graphics or using a tileset. I was able to figure out how to play it (with the help of the wiki for laptop-friendly controsl) in only half an hour of poking around, mostly.
cjzhang··on The Brilliance of Dwarf Fortress
Mostly I play it because I like chaining tame hydras in front of the bridge that leads into my trading post.
cjzhang··on Is it a good idea to personally email new beta signups after the sign up?
I don't think it's creepy, as long as you don't bring up information that might be too personal.

A rule of thumb I read was "Would this be creepy if it happened in real life?", and here you'd be analogous to "a restaurant owner asking a customer how their experience is on their opening day", which is totally normal.

cjzhang··on Google+ can now hide your gender "in response to user feedback"
Actually, they introduced the concept of private fields and restructured all their architecture to allow for profile fields to be optionally hidden...

Oh wait, they already had that.

cjzhang··on XKCD's Randall Munroe on Google+ requiring your gender to be public
Are you saying you should be allowed to use racial slurs because disallowing people to say them doesn't make them less racist?
cjzhang··on XKCD's Randall Munroe on Google+ requiring your gender to be public
Because when they complain about being sexually harassed or uncomfortable with the attention they get by being seen as a pair of tits, men invariably say or imply that they're being unreasonable for being offended, which doesn't solve the problem itself (which is that they're offended)?

I thought the "please let me know" in lowercase while almost everything else is allcaps was a nice touch.

cjzhang··on Ask HN:I need $2500000 in 3 years.
I don't think you can get more than 100k for one, and even that sounds high. You'd have to find 25 people with two working kidneys, which is almost definitely going to take more than three years (and a lot of ice).
cjzhang··on Ask HN:I need $2500000 in 3 years.
Prostitution? But even that isn't going to hit $2.5 mil in three years. More likely, you'll need to make all 2.5 mil in your third year, and spend the first two building yourself up.

You could try doing some tricky loophole pyramid scheme stuff using cryptocurrencies like Bitcoin? But that's also pretty scummy.

cjzhang··on Ask HN:I need $2500000 in 3 years.
Do you have any skills?

Barring that, you could try to rob a bank or something.

0%. I don't need a discount to buy high-quality hardware that I need.

Oh, wait, do you mean "what's the minimal discount I can offer to make you impulse buy something you don't actually need and that might not be as good as the alternative"?

:D

That's meeeee~ But to be fair, it's not a "seemingly" direct connection, it's an actual direct connection.

In a company with no sales or marketing or support staff, who do you think answers support emails?
