The problem facing people who intend to work with data that does not yet exist becomes one of feature selection: what data matters and how do we use it? For NLP tasks, does stemming matter? What about part-of-speech tagging?

Indeed, I worked on machine learning in NLP (fluency ranking, parse disambiguation). As a general rule, roughly 90% of the improvement of models is in clever feature engineering and exploiting the underlying system to get more interesting information that improves classification, 10% you get from using more clever machine learning techniques than, say a standard maxent learner with a gaussian prior (for linearly separable data).

For instance, the last relatively large boosts of the accuracy of the parser developed by our research group came from feature engineering:

"Lowest common denominator" for non-native English speakers

There is the CS theory aspect to it, of course. I don't encounter that all-to-often in my daily development. Things I encounter that definitely took me as long to learn, if not even more (in the context of web development):

- decomposing my code into patterns, abstractions, without going overboard,

- documenting stuff so that I will understand or other people will understand things in 6 months time,

- writing code on a team,

- having a good project workflow to handle source code versioning, releases, packaging

- knowing how to deploy things to a multitude of servers

- debugging caching problems, optimizing a DB for performance, understanding runtime performance of javascript,

- dealing with customer expectations,

- dealing with deadlines, unexpected events, etc...

- dealing with legacy sourcecode of hundreds of thousands of crappy bullshit.

Even in the aspects that "could" involve more theory, like optimizing a DB for performance, I find that theoretical aspects have pretty much nothing to say. There may be some CS involved on the patterns / abstractions level, like which data structure to choose or how to structure a communication protocol. But to be honest, I don't really have the time and the need and I just resort to whatever library people think is cool and stable. And that works pretty well.

None of the things above is simple, and pretty much none of it is taught in CS. And that's what makes a good developer I think, not whether I'm able to bang out a petri net or a neural network.

Not paying taxes harms people??? That's pretty funny.
Yeah, it harms the person not paying taxes.

Your false assumption is that people (as a whole) wouldn't pay an equivalent amount, or more, to charitable organizations or government, if they were not compelled to pay taxes. It's very closed-minded. I'm actually somewhat shocked at the responses on HN, because this crowd usually doesn't jump to unproven conclusions.

> Not paying taxes means that people take from society without giving back their fair share. [citation needed]

> Not paying taxes means million of kids sleeping hungry for no fault of their own but being born in to wrong parent. [citation needed]

> It means crime running rampant, as there is no police to stop criminals. [citation needed]

You, too, are making the leap that compulsory taxes are the only way to raise money for services. It's already been demonstrated numerous times, every day, that voluntary contributions can fund every one of these services. Not only that, but it can be done more efficiently than through a tax system.

Point by point: first addressing People who don't pay taxes don't pay their fair share. It seems to me that someone like Bill Gates or Warren Buffett (who happen to be the EXTREME, so should be great examples to PROVE your case), actually pay FAR MORE than their "fair share" (whatever that is - apparently you have some sort of formula), by donating vast amounts of wealth to charity (to keep kids from sleeping hungry).

People cite Romney as an example of someone "not paying his fair share", yet he gave far more to charity than most people.

Great use of the "Think of the Children" argument, by the way. Suckers everywhere would fall for it. But the fact remains that charitable organizations, through VOLUNTARY contributions do tremendous work in the US and around the world. Filtering charity through government bureaucracy and waste, in an effort to "help the children" is nonsense. People WANT to live in a society free from starving children, which is why charity does as well as it does. Imagine how much MORE it could do, if we weren't FORCED to pay the government.

People also want to live in crime-free environments, and people with the most to lose may have extra incentive to do so. So much so that private security forces are funded all the time voluntarily.

I haven't read an argument yet that has convinced me that I can decide what someone's "fair share" is, and force them to pay it based on MY arbitrary decision. I DO have a sense of what is reasonable for me to pay, and I do believe in generosity. But I'd rather give because it's the right thing to do, not give because someone made me. But I still willingly pay my taxes "honestly". I just don't think it's right that I dictate how much someone else pays.

As I have shown, the argument really can't be extended to theft. Freedom does not extend to harming others. "My freedom to swing my fist stops at your nose", or whatever that saying is.

Not paying taxes does not inherently harm anyone except the non-taxpayer, who goes to jail. There are plenty of other ways to "pay your fair share" as you say, without being forcibly compelled to do so.
Interesting idea but I'd hate to maintain that.

One of the lessons I've learned in my startup life (2 years) was to never deal with people who aren't competent with execution - what's the right thing to do, how to reason about it in a logical way, how to do it, how to finish it, contingency plans, etc.

"Try him out for the junk drawer job in the startup — CEO" is a terribly easy mistake to make, when you're still at early stage with nothing to show. I've done this for almost all the positions in my previous companies - programmers, "product" guy, all the way up to the CEO and investors look-alikes, and I regretted it every time.

When my CEO was still a business school student of a certain prestigious university, I thought he's well connected and would be a valuable partner later. The company did well for a time - but mostly besides him. Once he took over the reins, everything went downhill and the company never came back to its former glory - despite the CEO's claims of "funding is near", "I'm good friends with <insert big name here> and he'll cough up $50k without a blink" for a full 2 years. Every time I called him out for non-performance, he plays the "CTO is not a team player" card. But I believed him, for 2 years - all the way until he badmouthed his partner - me - to his friends right in front of my eyes. And for quite some time I actually thought I should keep the company breakup somewhat secret. Silly me.

Bad "product" guy... got him because he's a friend and he looked somewhat experienced. Ok.. now we've agreed the product would do this and that, now draw me something please? Uhh... wtf is that? He stayed for a few months, was fired, but caused the company some trouble after that.

Bad programmers.. went through quite a few of them, mostly contracted. Some even from big named universities with very impressive looking resumes. Again, hired them because of a sense of urgency (e.g. need to demo X to VCs soon!), so I lowered my bar to what I thought I could get. Wrong - those ended up wasting time rather than contributing.

At the end of the two years, I think I must have went through 2 dozens of people, co-founders included. Of the 2 dozens, only 2 of the choices were right - one programmer, one junior product guy. The others are all a waste of time.

If I were to do a startup again, I'd be super careful at picking who I work with. PG's advice at getting a co-founder? Yes it's definitely needed. But trying to do something investors like while sacrificing quality? That's the #1 startup mistake to make, IMHO. Don't do that.

Static vs 'dynamic typing': The personality-factor. (2008)
Not necessarily. For example you could have many read heads and read from the disk much faster by reading in parallel. It's complicated to do, but it is possible.

You can also increase the areal density, which means more bits fly past the head per second, which also increases speed, even though you can't increase the rotational or seek speed.

I recently evaluated different CSS-preprocessors for one of our projects.

Isn't this a perfect use case for a branch?

We had previous experience with the preprocessors, but they behaved differently used in our context with modularized CSS, lots of imports, using our custom watch script, etc, so we had to try them out in the actual project.

A cool hack, but I can't help this feeling pointless in practice.

It solves the problem of using Node userland code to do heavy computation. But

a) serious developers know better than to do heavy computation inside of Node anyway, and

b) it comes at an enormous, almost unforgivable cost: working with C++ is a nightmare compared to working with Node when it comes to realtime web projects (I've been in those trenches)

What would be exponentially more useful in practice is a concise, well-documented way to hook (multithreaded) C++ code into Node's engine.

But that wouldn't be nearly as sexy as a promise of Node, but with native performance.
