That's quite interesting; I don't see how one can really so soundly beat the disk configuration, but it certainly can be matched by something similar. It was posted about quite some time ago: http://orion.herokuapp.com/past/2009/7/29/io_pe

I don't understand where people are getting this meme that the GPL or FSF has anything to do with (not) charging for software. It's about protecting the people you distribute your software to, by affording them more equivalent rights you h

When criticizing a piece of software as popular as MySQL, offering a solution is an exercise in futility: it only leads people to think that the author is wrong because the alternative posited is wrong for them. See the endless MySQL vs. P

I believe support for this is fairly common among the usual suspects but is by no means universal, as you point out.

The latter. Such as big.js (not an endorsement, my understanding is too weak for that). Just about every practically used programming environment from every walk of life has such a thing in the standard library, and I suppose they are the

It seems your question is "why is there a 'private' variable convention, for something that isn't enforced by the language?" The shortest answer is that it changes how people read the program and treat symbols branded with the underscore. E

That's faster, but I think can be a poor trade-off because: 1. The speed gain is negligible for most programs 2. The addition of any pricing that requires fractional cents will require careful work to handle unit conversion to maintain inte

Perhaps more pervasive and despairingly problematic is number representation. JSON only, per specification, supports arbitrary precision numeric representation. However, Javascript is -- also per specification (as I understand it) -- enti

What's wrong with not enforcing privacy? I have not seen privacy be abused writ large in Python programs, except in cases that are very practical (mostly finicky forms of testing that hit a few critical code paths). I have fairly recently w

The other inquiries are: Is this problem really solved by the license? The example given (Linux distributions) is not a good parallel to a language implementation. As per earlier, this is more like worrying if people will come up with thir

by fdr 14y ago
It is a practical problem. The presumption is that the unusual license makes the language's implementation less amenable to survival. I can't justify a reason to absorb that much risk over the lifetime of maintaining programs written in the

They don't have the power to block a release if a three year old laptop is broken. Hence, not nearly good enough. If there was a System76 distro and it wasn't terrible in other dimensions then we'd be talking about something interesting.
