Somebody really needs to solve this problem. I've given some thought to it, but I haven't come up with any idea that's a slam-dunk.

You don't necessarily lose privacy by making up a username and password for a site. You do lose some privacy if you use social sign-on or the site requires you to provide an email address that's verified. My pet peeve is the arbit

Is it possible that women may be exercising their free will by choosing to go into fields like medicine and law not into fields like computer science, simply because more women prefer the former over the latter? It's apparently impossi

I think it was more disappointment at not being asked to speak about what she wanted to speak about.

It would be cool to be the programmer of a computer the size of a semi truck. It probably did the work of a pocket calculator, but it looked impressive.

Investing in a community is a gesture of goodwill. That could be the major legacy of this.

Even the connection between exercise and weight loss can be questioned. I highly doubt that gyms will solve the obesity problem. That said, I'm sure the Brazilian people will appreciate the gyms.

You definitely see lots of things like (string? x) even in Lisp. It shows that some types are unavoidable. (Though frequently the type information is just used as additional information.) Typecheckers definitely do things. But are those thi

I guess I wasn't clear. You could say that a line of code does something if it generates instructions for the cpu. `x = y` would generate at least one instruction (probably some kind of mov on an intel system), which would instruct the

What I think is cool is getting computers to do things that are interesting. Types don't do anything. I find them hard to get excited about.

I wonder if type erasure is profound, or if it only sounds profound after being hypnotized by type theory.

Back when I had debian on my home machine (a number of years ago), I experienced that dpkg would gradually lose track of the state of the system and become less and less useful over time. Once things got incoherent, there was no putting it

True. I don't expect that nginx would make them equal. But it would be interesting to gather more evidence to support the hypothesis that async I/O is the difference.

It sounds almost too good to be true. The bottom line (as always): * How hard is it to use? * How easy is it to break?

If you want to write C++, just compile it to javascript: http://kripken.github.io/mloc_emscripten_talk/gindex.html#/ Ridiculous?

It's not clear to me exactly how it came about that javascript is asynchronous. My suspicion is that in the earliest days, javascript was single-threaded simply because that made the implementation simpler.

Indeed. That's what node.js is for. I was just nitpicking the article's explanation. It would be interesting to see a breakdown of what makes the apache+PHP solution so slow. apache probably eats a lot of time by itself. Are you u

PHP is a lot easier to use. Which is pretty much why it's already king.

nginx + FastCGI would probably put PHP on a more level playing field. The test isn't completely invalid, but there is a lot more going on than what is described. It's a bit misleading to say that the server blocks waiting for file

Issuing commands to a computer with a "mouse" -- ridiculous! It will never work. More seriously-- why does this need funding? If the idea is clear enough and people see a need for it, someone will help finish it or write their own

Only computation-heavy code will show a difference. And the disparity is going to vary a lot. Some code will be easy for Java's optimizer and won't give C++ any advantage.

It's worth remembering that native code isn't fast automatically. An unskilled programmer, for instance, could easily write C++ that's slower than Java. There are a few possible reasons Fortran wasn't faster: 1. Fortran&

The type of code makes a big difference in how it will perform relative to C++. You also have to be somewhat expert in each language. You can write arbitrarily slow code in any language. It's not easy to be sure that you're giving

It is very good. But it's not quite fair to compare it to, say ruby or PHP, because it still requires a compilation step, and it's still pretty demanding on the programmer.
