glibc is not the only libc in existence. It is reasonable to ask that applications support systems other than those developed by GNU.

"cwd[] should be MAXPATHLEN bytes long" This is actually a common mistake — PATH_MAX and the like are not guaranteed to be defined. In fact, in POSIX it is literally impossible to ever know whether your buffer is long enough. Your best bet

This post literally makes no sense. I skipped the beginning diatribe, but the bullet points as to why functional programming is an "abomination" are completely false. FP is not bound to threaded concurrency; map-reduce is even named after t

I'm sorry, did you read mine? "If you want to handle NUL, simply use length-annotated slices instead of C-style NUL-terminated strings." Seriously though, using 0xFF as a UTF-8 string terminator would be a terrible mistake.

No. NUL is backwards-compatible with ASCII, and is used everywhere. Choosing some arbitrary invalid UTF-8 byte for use as a terminator would be a terrible decision. If you want to handle NUL, simply use length-annotated slices instead of C-

This is a great resource; it was extremely useful when I was writing a UTF-8 library myself. I found the UTF-8 stress test file is particularly useful to run tests against: http://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-test.txt

The problem is that such a language may have a mathematical basis but that alone wouldn't be able to convey anything besides mathematics. It can demonstrate intelligence, as used in Carl Sagan's novel Contact by broadcasting a sequence of

I'm pretty certain that's not what the parent was implying.

This reminds me of Patrick McKenzie's article "Falsehoods Programmers Believe About Names". http://www.kalzumeus.com/2010/06/17/falsehoods-programmers-b...

As much as I agree with the rest of the article, I have no idea what is meant by this "implementation leakage". Relative and absolute paths are a part of the fundamental Unix interface.

One problem here is that because of the complexity required to make a modern garbage collector manage memory effectively, when the GC fails to do its job properly it is far more complicated to fix ('optimise') than in a language with explic

This is one of the examples I use to explain why higher-level functional languages can be more drastically optimised than lower-level imperative languages. These fusions are also sometimes called hylomorphisms.

Wow, this is the first I've heard of this, thanks! I take it from that blog post they don't have equivalents to the commands [XYGV!] I talked about, in e? Still, awesome stuff.

But only that of certain social circles. For example, it fails miserably (imho) as a "hacker's language". I suspect the social and technical aspects of a language are inextricably linked.

This is the one reason I stick with Firefox. In Chrome if you search for the name of a YouTube video, with a string you know was in the title of the page, you're very unlikely to get that page as a result. If you're lucky you'll get another

You may as well just open up notepad and type "Hello, world!", and leave it at that. HTML is not a programming language; if you want to program on the Web you do have to jump into JavaScript.

Something I would love to have is a debugger for an interpreted language which visualises the program's state as a graph, say, and you can wind time forward and back. Then, as you make changes to the code the visualisation updates according

It's "Xv6", not "X6v", btw. It's a kind of portmanteau of x86 and V6. Edit: (For context, the submission title was originally "X6v".)

I've just done some testing, and my sudo (1.7.4p6) does honour NOPASSWD in /etc/sudoers, when I sudo -su to any user. Are you sure your configuration is correct?
112.
by lubutu 15y ago
That's possible using sudo -su user (which looks similar, but doesn't hand over to su).

by lubutu 15y ago
Whether sudo sets $HOME depends on your /etc/sudoers configuration. Alternatively, sudo -Hs .

su is unnecessary; sudo -s is equivalent to sudo su , but allows the admin to restrict who may sudo to whom, for which programs, and so on.

Well, duck typing can still be statically checked, so I'd argue that dynamic typing is more misguided. That said, I do agree that duck typing is fundamentally flawed. I think swans actually don't quack, they honk , but so does a car. Here

What it is to be 'a lambda' isn't particularly well-defined. If we define it to mean an anonymous closure then Java certainly has them — so long as its free variables are final (it closes over references ). On the other hand, if we defin

Yes it does. As you drag it back from the edge it returns to its 'desired size' (the user's last explicit resize).

The Haiku window manager does exactly this, but it also resizes the viewport such that the scrollbars are always visible. I've always thought it would be a great feature in other stacking window managers.
