As with the website, that paper discusses only the speed of BCrypt. There is no cryptanalysis at all, and no indication that BCrypt was submitted anywhere for peer review of its cryptographic soundness. This doesn't mean BCrypt is unsound.

The question is not whether BCrypt is backed by Blowfish, the question is whether BCrypt uses Blowfish in a way which is cryptographically sound. If it does not, then an attacker may not need to use brute force. Assuming the author has

I'm not so sure. The other side of the coin is that ``{MD5, SHA1, SHA256, SHA512, SHA-3, etc}'' have had extensive peer review in the cryptography world. There's a long history of ``clever new ways'' to use existing crypto algorithms turni

You mean other than that it's a tool used to launch DDoS attacks? Joke aside, Host: is optional in HTTP/1.0 (it's mandatory in HTTP/1.1). I would not be surprised if blocking on this cut out some set of proxies and spiders out there as wel

Flagged. Calling Assange a "homeless beggar who wants to take a shit on your carpet" adds nothing at all to the debate. Amazon has every right to turn WL away. That they chose to do so is, IMO, unfortunate, for the reasons laid out here: h

Note that this experiment (balancing an inverted pendulum, then moving on to balancing an articulated inverted pendulum) is one of the examples from the original Papert LOGO papers of neat robotics problems which grade schoolers can underst

Like running sshd on another port (to stay on topic), it doesn't make the service more secure against someone who knows it's there, but it makes it less visible to automated scripts probing the standard location for known bugs.

Agreed. There's something slightly condescending about the book -- about an adult trying to think of awesome `childlike' things, and only coming up with outlandishness. I've tried encouraging my children to remember and write down their dr

Which is why API or other names with 'new' in them are a bad idea. :-)

All of which is a workaround for the fact that there is no explicit way to declare a c++ class to be abstract-only. What happens if you do have shared logic to put in the abstract base class's destructor? It can't be pure virtual, and you'

This is a kind of, uh, basic point, but who writes a web site to promote a new programming language and doesn't include any example code on the site? (Never mind a language tutorial or reference manual.) I get that there's a forum, but the

Looks like scala to me: def playwith_seq[A] (seq : Iterable[A]) : List[A] for (x <- seq if x % 3 == 0) yield x * x

There _is_ a Little MLer (with examples in Caml and Standard ML), which teaches type-based programming very well, and would be worth reading for anyone setting out to learn Haskell, I imagine (I respect Haskell's purity, but program in ML a

On the bright side, forcing yourself to write bulletproof code for the book may well be the best way to become qualified.

For what it's worth, this is a quick hack done in two train rides, but it does try to be correct, and relatively general. Let me know what you think...

Be took this approach, for what it's worth -- they sold two models of BeBox, and all developers were given the slower one. They pointed this out very proudly in their launch pitch for BeOS, a pitch which focused as much on performance / con

Yeah. Another way to look at this is that traditionally Java ports fell into two categories: a.) The platform was important enough that Sun would lose credibility if there wasn't a good JVM available (Windows, Linux), so Sun (now Oracle) d

I guess I don't get it. The Mac App store is... wait for it... a store. Just like the physical brick and mortar Apple Store, it carries not the universe of software available for the Mac, but a screened subset of that software that Apple

This seems central to Ravitch's argument: ``For many people, these arguments require a willing suspension of disbelief. Most Americans graduated from public schools, and most went from school to college or the workplace without thinking tha

Without agreeing or disagreeing with the unnamed official, I have to admit that HTML5 feels a little like HTML3 to me -- it's following up a lean markup language (HTML2, HTML 4/XHTML 1.0) which was explicitly defined as an application of a

One tip on writing announcements like this -- always include a blurb at the start saying what your product, um, is. I've now read the full announcement. I know that there is a new version of Phusion Passenger coming out, and that a beta is
