If you know how an insertion sort (for example) works, then you can pretty much answer all your questions fairly easily. Knowing algos is good, but does not in itself make you competent in every respect.

Having said that, I am not trying to be critical. I completely agree that having a discussion like this is extremely valuable and can let you find out a lot about a person and even eliminate most of the chaff (although I have met a couple of people who I wouldn't necessarily hire, but who could have done well in a discussion like that).

After your discussion, you might even decide you really like a person, but does your team like them? How about this, can you tell if a person can stick to a deadline? A longer discussion is necessary before this becomes apparent.
The other reasons can often be more important than programming skills. Programming skills are arguably easier to acquire than people skills.
It's cargo culting more often than not.

For some reason, people don't follow good advices which require changing code logic, refactoring and such: they follow advices where you need to format everything in the longest possible way and write a lot of boilerplate.

Because it's just easier for some people.
I agree there is no silver bullet. You may not agree with the article, but it id generate some discussion and got people to share their thoughts (including you :)). This way we can all learn from each others experiences and discover methods that can work for us.
Hmm. Here, extracted from the comment above, is the basis of my point of view

I submitted here to HN a link to a PDF which is
copyrighted. That has been uploaded to scribd
without acknowledgement. When I contacted scribd
to ask them to take it down they said it was the
responsibility of the copyright owner to make a
formal request for takedown.

Who ticked the box? I certainly didn't. Who checked
that the person ticking the box had any right to do
so? Scribd certainly didn't.

From those facts I concluded:

Scribd make no effort to ensure that copyright is
not breached. There is no traceability. Their
"efforts" are ineffective and insufficient.

There was a breach of copyright, and certainly I wasn't contacted. I'm assuming the author wasn't contacted - scribd certainly don't appear to be proactive in contacting the author of everything uploaded.

Someone has uploaded copyrighted material to scribd, and it's still there. Hence I conclude:

If someone uploads material to scribd in breach of
copyright, there are no sanctions, there is no
culpability.

Now, would you care to point out the strawman argument? I would be delighted to learn that a service I have hitherto thought of as the scum of the Earth are, in fact, noble and just.

No, really, I would, and I'm just being selfish. Currently I get very angry thinking about their existence, and if I learned that I was wrong I'd be happier.

Please.

If you can't, then I suggest that when you say:

... you seem to have a insider's view into Scribd's
back end. If not, then you're just bloviating and
making strawman arguments that don't really stand up.

then your logic is faulty.
I didn't disagree with you :) My point that the US disproportionately rewards the high end of a curve was an observation as opposed to a value judgment. This has caused many social problems, and IMHO is the wrong way to run things. Nonetheless, for people who feel that they can profit much more in this environment (i.e. top-end-of-the-curve types) it's very attractive.

"Top tier American schools are highly-overrated and highly overpriced these days."

Perception, in this case, trumps reality. The reality is that a MIT degree is worth a hell of a lot more in salary than a random eastern European university. Whether or not the education truly is better is moot - people want in on the USA because it generally will lead to a better life than they've got now - assuming "now" is an underdeveloped country.
Aha! You, sir, have hit upon the greatest reason to be optimistic about globalisation; even though the evil soulless multinationals <warning, satire> are currently destroying good, well-paying jobs in developed nations and creating nasty, hellish, unsafe, penurrific jobs in the concrete slum-nightmares of the Third World, they have to move on to new concrete slum-nightmares every so often when the locals get too rich to endure slavery!

The key fact is this: There are a limited number of slum-nightmares to move on to! One day, the t-shirt manufacturers will find that Darfur has become too well-heeled, and look around, and curse the skies, because there's nowhere left to exploit!

And the world will be doomed to become more homogenous, more wealthy, and more high-standard-of-livingy every single day.

Mwahahahaha!
I really enjoyed your point by point take on this.

"adding a feature to QNX won't make the kernel bloated"

Yeah, you have a piece of code named "the kernel" which you can point at and tell that it isn't bloated. But you can do this in Linux too, if you compile everything as loadable modules. That is just creative accounting of the bloat.
Not to mention the fact that many of those protocols had to be reverse engineered.
The second problem is really good. I just thought up a solution that, though more complex, seems to me much less mysterious, and the 2D case does shed guidance on 3D.

One-dimensional case:

a1 < a2

Two-dimensional case:

a1*b1 < a2*b2 (area)
a1+b1 < a2+b2 (sides projected outwards, triangle inequality)

Three-dimensional case:

a1*b1*c1 < a2*b2*c2 (volume)
a1*b1+a1*c1+b1*c1 < a2*b2+a2*c2+b2*c2 (surface area, projected outwards)
a1+b1+c1 < a2+b2+c2 (our problem)

Notice the pattern already? If one N-dimensional box lies inside the other, the inequality holds for all elementary symmetric polynomials of box dimensions.

http://en.wikipedia.org/wiki/Elementary_symmetric_polynomial

To prove it, we need only notice that the symmetric polynomial of degree M is proportional to the average volume of the M-dimensional "shadow" of the N-dimensional box, averaged over all projection directions uniformly. (To convince yourself of that, work through the two-dimensional case.) On the other hand, if a box lies inside another box, each "shadow" of the smaller box lies within the corresponding "shadow" of the bigger box. Done!

Questionable -- they would certainly learn different things if they did it in their basement. For example, so much in university is already set up for you -- constructing your own lab in your basement, calibrating machines, writing custom software to run experiments, etc. would be quite a learning experience. (I'm talking about experimental fields here.)

But more importantly, in universities you are guided away from things that do not work usually without entirely understanding why. Through independent study, you would go down these incorrect paths and have a much richer understanding. Instead of doing things how everyone else does them, you'd gain new perspectives than the status quo, and this would give you a leg up.

Of course, this all presumes that the student is extremely self motivated. Unfortunately, even at the graduate level these students are very rare. This is why some professors are very hands on and others are very hands off -- different students work best at different levels of independence.
Yes, Pearl's Causality is pretty dense. The trick to reading any research monograph is to realize that you're not supposed to read all of it, nor are you necessarily supposed to read it front-to-back. Once you realize that, Pearl's Causality is actually very accessible -- read the introduction to each chapter, read the text sections in that chapter that look interesting, and study the mathy parts that you find relevant.
Same here... their support is awesome, and upgrades are easy. I would skip the 256 slice if you are doing anything but hosting simple static websites though...

I found that even a single Wordpress install was able to bring my 256 slice to it's knees each night when it was indexed by search engines (until I installed a bunch of caching plug-ins that is).

I was quite fearful of using Slicehost as I have practically no knowledge of system administration, but their support and tutorials made the whole process easy. I've done it a couple of times since and I'm getting faster each time!

Which ones do you mean?
I think this shows the amount of bloat in an Open Source package increases with how widely used the project becomes. As an article posted a couple days ago on HN pointed out about 75% of Linux development is done by corporations these days. Those corporations often times create the same "good enough" code that most proprietary developers do.

Now the theory behind Open Source is that developers around the world can see bloat and fix it. But with very few exceptions the corporate developers aren't going to make their code more efficient. So you have 75% of developers creating bloated code and at best 25% left to fix it.

Meaning the amount of bloated code easily overwhelms those volunteers who are willing and able to fix it.
Does bloat mean too many features? In that case I'd say those features are there because someone needs them. They don't all have to be loaded. In a monolithic kernel that has modules, load the ones you need. In a microkernel, load and unload as needed on the go.

Then there is the support issue. In Linux, all the modules must be maintained by the kernel team. This may constitute bloat as the team may have an unnecessary amount of code to maintain. Some modules may only be used by a few people. The issue isn't the features, but rather Linus's philosophy.

From his posts, it seems he like to keep changing kernel APIs as he sees fit. If you have many modules, this creates problems. Without a strict API, you will frequently break modules and thus create a lot of maintenance work. Fixed APIs are both very important and very good for large scale collaboration. Without standards like POSIX or the Windows APIs, we wouldn't be where we are today.

The second aspect to this is security. Say you built a very stable API and let others make modules as they need them. In a monolithic model, to maintain security you must audit every module. Thus for Linux to stay secure, the kernel team would need to either declare many less used modules as "tainting the kernel" or audit them all: a lot of work. In a microkernel model, the kernel team, so long as they designed it right, can let users build modules without audit.

Saying something has too much bloat is ambiguous to the point of being useless. Many people use that term simply as meaning slow, or a lot of code, or even poorly designed code. It's always better to describe things precisely. If it has too many features, say so. If it has bad design, then state that.
Unemployed doesn't mean zero income or zero utility. If the utility you offer them for working is less than the utility they get from being unemployed they won't take the job.

There may be enough labour to keep everyone employed, but not enough of that labour has a high enough value that it's worth while for people to do it, and thus you have unemployment.

Said in a simpler way: either Linux is poorly designed, or that amount of code is necessary for a general purpose kernel.

This assumes that someone needs and actively maintains every feature in the code.

Yeah, lived there for some time. The traffic there is truly remarkable. It looks insanely dangerous, but I dared do things there as a pedestrian that I wouldn't do here.

For example, I once tried to cross a busy street but didn't plan my route properly (like I would do here) and got stuck. Couldn't move forward or backwards and traffic was coming to me. I was worried for a few moments, but then I noticed that traffic just flowed around me. No horns, no near accidents, no panic, just normal flow.

You can always change carriers that restrict what you want to do though. When the government restricts something you can't change to something else.
OS X is not a microkernel and hasn't been one since 10.0. It is a hybrid kernel called the XNU kernel. It's Mach microkernel based with some low layer BSD smothered on top.

It would be interesting to see how the original Mach microkernel runs on modern hardware. At the time, the context switching of the Mach kernel was making performance poor. But this was on 300/400 MHz machines.

It's entirely possible to bake your own bread or grow your own vegetables today, do you do that? Food independence!

I just don't see why division of labor would decrease. In the past it's pretty much always increased with growth of technology. As Robin Hanson said in "Dreams of Autarky" http://hanson.gmu.edu/dreamautarky.html :

I suspect that future software, manufacturing plants, and colonies will typically be much more dependent on everyone else than dreams of autonomy imagine. Yes, small isolated entities are getting more capable, but so are small non-isolated entities, and the later remain far more capable than the former. The riches that come from a worldwide division of labor have rightly seduced us away from many of our dreams of autarky. We may fantasize about dropping out of the rat race and living a life of ease on some tropical island. But very few of us ever do.
I've had two. One was really really short and the other was a bit longer. Both were awesome. I've considered dream-notes, but its effort. Maybe one day.

Yeah, there is the FUSE project: filesystem in a userspace. There are lots of interesting filesystems using this e.g. NTFS-3G, sshfs or ferrisfuse. These projects are valuable and most of them doesn't belong to the kernel as they use userspace libraries for network protocols and xml parsing.

Unfortunately native disk file systems like NTFS-3G is lot more slower than their native counterparts.

Consider the following EU definition of a free economy:

The freedom of movement for workers is a policy chapter of the acquis communautaire of the European Union. It is part of the free movement of persons and one of the four economic freedoms: free movement of goods, services, labour and capital.

But of course is only applied within the European Union. Foreign workers can actually expand an economy - not contract it (See US, Austalia, Canada). By restricting immigration, the jobs get exported rather than stay home. Would a more permissive immigration policy by the US have kept these jobs home? I believe it would. The world now has reached a stage where goods, services and capital almost move freely but not the last resource the labour. By slowly opening the gates the world will slowly adjust to a new Global Economy.

Ask HN: Moving to SF Have a couple of questions
Hi,

I'm a product director who also does front end development. I am moving to the SF area and wanted to ask a few questions.

If you were looking to hook up with a startup and start meeting people in the community where would you live? From my research I think mountain view would be a good place to live that is not super expensive. I am working on a few of my own startup ideas and am bootstrapping it myself for the first few months. My work related stuff has already won a few awards so would love to network with any rails/django coders in the area.

Since I really don't know any of the areas in SF except from what I read online about where new startups are going. I would like to find a place that would be within easy driving distance of meetups and other social/tech functions.

I know this is not a normal HN type question, but I think perhaps it could be of use to others that are coming to the area and need a bit of info to make the jump. (I know it would be at least useful to me)

Thanks for your help in advance.

The problem is that the declining population is temporary. Every area with declining population, except perhaps Japan which I don't know enough about to say, has sub-populations with higher growth. Eventually, those populations are going to become large enough that the population as a whole will start growing again, and will continue increasing until it reaches the rate of the high-growth formerly-sub population. It's just a hiccup. Unless something external - singularity, war, whatever - intervenes.

In fact, since the 1970s, the almost sole cause of poor crop production has been political; there have been droughts, but only a small portion of the poor countries have been affected by them at any given time. The most common causes have been either the gov't cutting off supplies to "rebels" or politicians beholden to poor urban masses holding down food prices so much that farmers can't sell their crops for enough to break even, so they grow only enough for themselves (or both together, with other stupidities thrown in, like current Zimbabwe).
