There's another "Feynman Algorithm" which someone mentions towards the end of the article: he said he kept a small number of problems constantly in the back of his mind and whenever he heard of a new trick or method, he tested it against his problems.

I once wrote a blog post about whether the opposite method is effective: you keep your favorite tricks and techniques sharp and always look for new problems they might solve.
Say you need both modularity and low level access in a given program. Can they be so entangled that you absolutely have to put both in the same language?

No matter how I put it, I fail to see how C++ can be better than C + (Python or Lua or Haskell, with FFI). Is the concept of using 2 languages at the same time so scary?
Very classy response, it gives me great confidence that you will go very far with your company in spite of silly things like this.

It definitely isn't fair, but media coverage is transient, long term what matters is business savvy, customer satisfaction and technology.

No two bit article featuring a 'me too' competitor, funded or not is going to make a difference there in the longer term.

I agree, and the entire thing leaves a poor taste in my mouth too. Techcrunch screwed up in not mentioning VWO, but only because it is the real innovative company in this space, and its product has been out there for a while. If this new one is newsworthy they should have at least linked to VWO in the review.

That said, I think the real fault here is with PG and YCombinator, who should know better than to fund teams to compete with single-founder bootstrapped startups that congregate on these boards. I mean... what's next Paul, a YC funded play at online bingo?

The team responsible for the JIT in Self went on to develop HotSpot (see http://en.wikipedia.org/wiki/HotSpot#History).

I find this part particularly interesting:

"there’s more dynamic range in these numbers too. Previously, the absolute lowest value any iPhone would report was -113 dBm. With iOS 4.0.1/4.1, the value is now a shockingly low -121 dBm. In the iPhone 4 review, I talked a lot about how although the phone is prone to dropping signal from being held wrong, it was measurably more sensitive in weak signal areas. I was shocked that calls and data worked seemingly unfazed at -113 dBm. It seems as though this increased 8 dBm of range below -113 dBm was meant to show really how much more sensitive the radio stack is - it undeniably is more sensitive. Both Anand and I were able to hang onto calls all the way down at -121 dBm."

On another note, I posted this article to HN 13 hours ago. Since this was my first submission I am wondering... does anyone know why my submission withered away, and this one rose to the top?

I'm often frightened by how spontaneously my brain seems to come up with something, because it could just as easily stop doing that and I'd have no idea how to fix it.

I once walked past a math book one of my friends had left open, glanced over, stopped, pointed to a formula, and said, "This is wrong." (Which it was.) I only did it that once, but it's the sort of anecdote you can tell for the rest of your life. And if my brain stopped doing that, I'd be screwed.

Serious question: why?

I understand an economy that does not produce any of its own goods is in a jam -- it's an external critical dependency that can be wielded like a club against you. But if you have adequate internal production, what does it matter if it's done by humans, robots, or hyperintelligent cyborg orangutans? It may take a generation or so, but the people who would have been manufacturing labor will be absorbed into other markets -- or should be, as I understand it.

"Writing down the problem" sounds trivial, but it's often the hard part. Once you understand the question, the answer is obvious (as a commenter said).

I have to break down complex problems in order to come up with questions that I can understand.
The really hard part is in finding the right way to break them down, because not all modularities and boundaries between them will help to solve the problem. But all of this properly forms part of Feynman's step one, of writing down the problem.

I also often get a sense of what the answer should be - but it's very difficult to even begin to describe it in words, let alone define it clearly, and even harder to prove it is correct. Yet... it almost always is correct. This is properly in Feynman's steps two and three.

Computers are useless. They can only give you answers - Picasso

It is by logic that we prove, but by intuition we discover - Poincaré

and so another, even bigger, computer had to be built to find out what the actual question was - Douglas Adams
That's unfair: YC doesn't bias against "outsiders". The point of YC is to find smart people with good ideas from anywhere. For example: you hear stories about people flying around the world to interview.

One of their main benefits is the connections they give you: connections they've cultivated with their "insider" clout. I would consider them a bridge between the insiders and outsiders: they take outsiders, find the best ones, and bring them in.

However, even that's overstating the amount of insiderness that exists. It's amazing how easy it is to network your way into the valley fold. Sure, that requires you to actually be out here, but that's a byproduct of the benefits of in-person networking, not some kind of elite mentality.

People have said it here several times already: TechCrunch caters to an audience. This audience likes to follow YCombinator, and Ron Conway, and a bunch of other well-known programs and people. It's business plain and simple, fairness doesn't come into play.

I can finish a 500 page book in about 4-8 hours. Building the scenes in my head is much more of a bottleneck than the actual mechanics of reading. Complicated scenes, e.g. The Pillars of the Earth, which is heavy on architectural terminology I'm not familiar with, and a huge amount of characters, e.g. Good Omens, slow me down considerably.

Also, being within earshot of people having a conversation slows my reading down to a grinding halt so my technique to read faster, outside of reading more, is basically finding a quiet place.

"Say you need both modularity and low level access in a given program.
Can they be so entangled that you absolutely have to put both in the
same language?"

That's not always an option if you've performance and memory constrains.

We're using Python only for high level scripting purposes.

If you've a performance critical function, where few data goes in,
long computation and few data out, then it's perfect to implement
this function in C and have a python function calling it.

But if you've a lot of data, then that's not an option. You just can't
copy all the data to C and then after computation back to python,
it will kill the performance gained by the C function implementation.

But also if you're trying to do complex operations on your application
object hierarchy, Python will kill your performance. Only compare
the time for a member/property access in Python and C++.

Taking you literally. $1,000 pm is $12,000 pa. Let's assume passive income from an index fund of 12% pa (for simple maths, though it's also the long-term return of the Australian stockmarket; bumpy short-term). So you would need $100,000 invested.

To save that $100,000 in a year, working 6 hrs per weekday and 8 hrs per weekend day (impossible to keep up) is 6x5+8x2=46 hours pw = 2,392 pa. You'd need to take home $41.8 ph (after tax).

It's theoretically doable.

That's a very clear and accessible explanation of what big O complexity is all about.

But (and that's a pretty big but), 'Big O' is not all there is, and once you've picked your algorithm based on the one that has the best expected runtime based on 'Big O', you really have to try to make sure that:

- your algorithm is executed with the lowest possible frequency

- you concentrate on those pesky n's that you eliminated during analysis to
make sure that you don't end up wasting all your CPU time on some
little detail somewhere

- you take in to account the effects of your code on caches and virtual memory

- you profile your code afterwards to make sure that all your assumptions regarding
the above are correct

It is very easy to pick the 'right' algorithm and still get crappy runtime if you skip those steps.
ISBN numbers and electronic distribution: What IS an eBook, anyway?
Damian Conway in Perl Best Practices recommends not to use negative control statements at all (unless and until).

So this would be a no-no:

unless ($this > $that) {
do_something();
}

He's happy they're used to postfix statements however he says that these should only be used for flow control. For eg.

for my $i (@list) {
next unless $i % 2 == 0;
do_something();
}

Pool.com sends out an email of their "Hot List" every day with a list of expiring domains (http://www.pool.com/hotlist.aspx?ia=hotlist). They send about 30 domains a day, and I guess in an average week 5 are interesting and you can register for them at the various auction sites (Pool has no guarantee of getting them on the drop) and then bid on them. Very few domains that are usable go for less than $100 though.

Not as good as Ryan's AI but a nice easy way to occasionally catch a good domain.
I find it all rather sad. BP has committed an appalling act of negligence however the parties operating the rig and the company that provided the Blow Out Preventer (Trans Ocean and Halliburton) still seem to be avoiding the worst of the flack.

I'm interested how this came about. They usually either try to match people who know common languages or they do more generic problems which don't depend on language. One important thing is if you said you knew C well (or even only "working knowledge of") then it's perfectly reasonable for them to ask you to write it in C instead of Java/Python/etc. Did the interviewers state they didn't Java beforehand? Did they say they knew another language you'd mentioned you knew on your resume?

My interview experience actually involved them hammering me on the languages I said I knew but wasn't an expert in. This is likely as they were trying to find out whether I was lying (or, put kindly, overstating) on my resume. From what I've seen there are a few people who put every language down that they've ever written hello world in ;)

I wasn't talking about web applications, and modern garbage collectors are not stop-the-world.

Not to mention ... stop-the-world garbage collectors have a good reason for doing what they do. They are defragmenting the memory. You get that for free, when in C++ you would have to deal with hell if your app is doing lots of allocations ... see the shit the Firefox devs had to go through to alleviate the problems of heap fragmentation, and its still a problem.
