ahlatimer··on The author of Nginx on why V8 is not suitable for web servers
Look at Pooter's comment history. He/she has been banned for some reason.
ahlatimer··on How to Score a Google Onsite Interview
He probably built it not because he needed it for something, but because he wanted to see how they worked. That's precisely the kind of person I'd want to hire. Someone so interested in this stuff that they build things to see how they work, not just because they're paid to do it.
ahlatimer··on Russia's Crime of the Century
Just because the US/AU/UK/Can are better places to live than Russia, China, N. Korea, or most of Africa doesn't mean we should allow the stuff Western governments are pulling to slide. I don't know if the countries that are orders of magnitude worse than the Western governments were always that way, but my guess would be that they were, at one point, not so bad, relatively. It was likely a slow path that led them to decline to the point they have today. I don't want to see my government go down the same path.
ahlatimer··on Why Twilio Wasn’t Affected by Today’s AWS Issues
Here's the article from Google's cache, in case it's unreachable for others: http://webcache.googleusercontent.com/search?sourceid=chrome...
ahlatimer··on Amazon Web Services are down
Easter, probably.
ahlatimer··on Stanford CS enrollment increase "downright scary"
That's the reason he gives for people initially going into CS, but he says that, once they get there, they tend to really enjoy the material. Apparently it wasn't so in the dot com bubble; people freely admitted to hating the material.
ahlatimer··on CSS: Our best practices are killing us
The problem with having repetition in your compiled CSS files is that they become bigger as a result. Depending on how much you care about page load speed, this can be an issue.

I'm not entirely sure what she's suggesting since I'm reading the slides without any context, but it seems, given the thing about cutting down css file size for Facebook, the method she's suggesting reduces duplication in the actual css file.

ahlatimer··on Can a complete novice become a golf pro with 10,000 hours of practice?
Well, you probably wouldn't ever get in the top 5% of marathon runners if you didn't have legs [1]. I'd argue that it's similar for something like programming. I think you'll find that some people lack the mental acuity or analytical reasoning skills to be in the top 5% of programmers. Those skills can be taught to a certain extent, I suppose, but I don't doubt you'll find people that would plateau well before breaking into "expert" territory. You'd likely find the same for someone trying to reach that point in golf or any other number of skills.

Do most people lack those necessary skills? I'm not really sure.

[1]: For the purpose of the argument, ignore prosthetics. AFAIK, there isn't anything similar to prosthetics for someone that lacks certain necessary abilities to be an "expert" programmer.

ahlatimer··on Is programming the new math?
I had a short stint as a research assistant for a prof who's using programming to teach high school seniors and entering freshmen math skills [1]. I'd have to ask him how the research is going now, but the preliminary results were encouraging.

ahlatimer··on Is gravity not actually a force? Forcing theory to meet experiments
The guidelines suggest different criteria for what constitutes "Hacker News" [1], specifically the first paragraph: "On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity."

Also in the guidelines: "Please don't submit comments complaining that a submission is inappropriate for the site. If you think something is spam or offtopic, flag it by going to its page and clicking on the "flag" link. (Not all users will see this; there is a karma threshold.) If you flag something, please don't also comment that you did."

ahlatimer··on Predator Object Tracking Algorithm
At least some of the processing could also be off-loaded to an accessory device. How much work is the Kinect doing vs. the actual 360?
ahlatimer··on Predator Object Tracking Algorithm
According to his website [1] for this, he says that "TLD has been tested using standard hardware: webcam, Intel Core 2 Duo CPU 2.4 GHz, 2 GB RAM, no GPU processing is used and runs in a single thread. The demands of the algorithm depend on required accuracy of the algorithm. Implementation for mobile devices is feasible." in response to "What kind of hardware it was running on?"

So, according to him, it is lightweight enough to run on mobile devices. I'd imagine there are also several optimizations that can be done (leveraging multi-core chips or GPUs, for instance) to make the performance significantly better than the prototype he's demonstrating now. Also, taking into account Moore's Law, we may not be able to run this on today's mobile devices, but surely could on tomorrow's. Given that research is generally a few years ahead of industry, I would expect that, by the time this would come to market, the devices will be more than capable.

ahlatimer··on Why I went with them and not you: feedback to an interviewer
Yes, but the number of potential bugs when going from OS X -> Linux are far fewer than going from Windows -> Linux.
ahlatimer··on Save IE6
SaveIE6.com was put together as an April Fool’s joke by the uptime monitoring service Pingdom. Due to the tremendous interest it has received we have decided to keep this site up and running. Thanks everyone for the great feedback and for enjoying the irony!

I guess they just didn't remove the conflicting text in their footer.

ahlatimer··on Don't distract new programmers with OOP
I don't know that OO's main goal is to be readable, but rather to manage complexity (which should help readability, but I don't think that's the focus). There's an inherent level of complexity in OO that isn't necessary when you're solving basic, learner type problems, but it can help keep complexity down when you're solving problems that have solutions that can't be kept in your head at any one time.

To put it differently, think of an algorithm that's constant time, but has a very large constant and an algorithm that's O(n). The constant time algorithm will be worse for small sets, but better for large sets (once n > that constant). That's the problem with teaching OO to people new to programming. You're adding an additional thing to an already difficult topic, and that thing you're adding doesn't really benefit you at that level of problem, but get to a bigger problem, and it starts to make sense.

ahlatimer··on Why cigarette packs matter
That's been my experience as well. I started because people around me started. I knew full well the potential health risks, the cost, etc., but figured I could stay a social smoker. I couldn't, and I smoked a pack a day for over three years now.

I haven't bought a pack in two weeks now, mainly due to switching to e-cigarettes. If you're interested in quitting, the e-cigarettes worked better for me than the gum and patch. Don't know how long this will last (hopefully won't buy another pack ever again), but it's not been nearly as excruciating as quitting any other way.

ahlatimer··on OS X Isn't for Developers
Installing Xcode to get gcc was already a requirement before this. I really don't understand the argument.

Funnily enough, I've never heard anyone mention it before this whole ruckus, even though installing Xcode was a requirement to get gcc in the past. No one has taken the time to build it themselves with the source that Apple gives out for free and host it for those that don't want to install Xcode.

ahlatimer··on OS X Isn't for Developers
You likely don't need printer drivers or a developer tool chain to get your computer set up enough to connect it to WiFi or ethernet. You probably do need different languages if the one the computer defaults to is not one with which you are familiar.
ahlatimer··on OS X Isn't for Developers
That totally outside the scope of this issue, though. If you feel that having to install Xcode to get a gcc install on a Mac, that's fine, but that's the way it's been for a while now. Apple charging for Xcode 4 didn't change that.
ahlatimer··on Git hits for github: are you awesome enough to be in the top 10 in your city?
Is the code on GH? If so, the people (myself included) who want to run this for their city could.
ahlatimer··on Abusing the HTML5 History API for fun (and chaos)
Bookmark navigation on OS 10.6.6 with Chrome 10.0.648.127 beta works just fine. Clicking the address bar doesn't work, though.
ahlatimer··on Apple’s iPad Still Has No Competition
He actually does mention Honeycomb: "No matter how good Google makes Honeycomb, the fact is, almost every company out there will be using it."

It's kind of a shitty argument, though, if you ask me. I don't follow the Android market all that closely, but it seems competitors are, in fact, doing things to differentiate themselves, even if they share the same core OS.

ahlatimer··on Which websites dropped the most in the latest Google algorithm change?
Fair enough, but the domain is already shown next to the submitted link on HN. It might not confuse you, but it apparently confused other people, and it's really redundant information anyway.
ahlatimer··on Nerd Fort
There's cospace: http://cospaceatx.com/

A buddy/former co-worker of mine works out of there, and he seems to really enjoy it.

ahlatimer··on Pandora Files To Go Public
That's fair. I think a large part of why you're not getting more upvotes is that Pandora seems to be far more popular than MOG. I hadn't heard of MOG until you mentioned it. I went to their site, and (assuming their suggestion engine and library is about as good as Pandora's or better) it seems to be all of the things I wish Pandora would be.

FWIW, you've caused one rabid Pandora fan to give it a look.

ahlatimer··on Towards Better Online Dating
Wait, what?

OkCupid seems to be at the forefront in this space. They get people in India to rate the attractiveness of new members and use that to limit your access to people significantly more attractive than you are.

Is this common knowledge? I'm shocked if it's true, but I'm sort of thinking there should be a [citation needed] after that.

ahlatimer··on This may be the best resume I have ever seen
I'm not even out of college, and I've already dropped the high school bit from my resume entirely. Does anyone really care what a potential hire did in high school once they've had a real job or graduated from college (save someone being an extreme outlier that completed most of their college degree in HS or what have you)?
ahlatimer··on Cached OkCupid Article: Why You Should Never Pay For Online Dating
Sorry if it came off as me saying that people in poly relationships aren't at all welcome on OKC, just that it's not universally welcoming.

I'd imagine how welcoming people are to others in poly relationships largely depends on where you are. People in El Paso, TX (where my friend and I live) are likely less open to that sort of thing than people elsewhere.

ahlatimer··on Cached OkCupid Article: Why You Should Never Pay For Online Dating
It might appear so, but a friend of mine who's in a poly relationship gets harassed fairly frequently on OKC because she's married.
