See Phrack 25: http://www.phrack.com/issues.html?issue=25&id=5 for what it was like when mkdir was not atomic.

This is a great one: Under POSIX, any write() to a fifo that has at least PIPE_BUF free is atomic. There's a neat trick I'd like to add that takes advantage of this: Multiple clients can use a message whose size divides evenly into PIPE_BUF

It's from an old (and famous) Zen saying: "Before I studied Zen, mountains were mountains, and water was water. After studying Zen for some time, mountains were no longer mountains, and water was no longer water. But now, after studying Zen

Am I missing something? There doesn't seem to be any way to pass a function in the function namespace as a variable without a closure.

No. You can use a master password to decrypt your encrypted password database. Your operating system might have a keyring service or an encrypted filesystem you can use to store your keys in. You might even use a hardware token, or some spe

I bind mine to modifier keys, like Alt, and Super. Then I can chord-resize windows and chord-drag them from the middle of the window without doing the one-hand-keyboard-one-hand-mouse move.

While I agree the "segfault policy" is a bad idea, if you've got dedicated hardware for checking invalid addresses, it seems to me that you should use it. After all, checking the null pointer is still slow. Combining a malloc wrapper with t

Not exactly the same thing. The R3RS that existed in 1989 lacked macros, had t and nil, and even allowed implementations to "call" strings. Even ten years ago, Python, as it existed in 1999 was a very different language than it is today. Mo

That need FK? Nobody needs FK: Anything you can implement with FK, you can implement with tedium, code duplication and transactions. Having FK in SQLite means less tedium, less code duplication, and/or fewer transactions. I can't imagin

1) stat() is a system call, so one system call is bound to be faster than two. 2) Sneaky users do this; they create files like /dev/shm/...\n-rf\n.. and you'd better know how to delete it correctly. 3) ??? 4) -delete is a GNU extension.

A correction: These aren't macros, they're fexprs. There are a lot of other interesting things on the site; the cola/idst stuff is especially interesting.

There are other uses for cut/paste besides CutAndPasteProgramming; for example, one may want to post a snippet to a comment box that doesn't offer a preview function. def foo(): if something: do_something_else print "bar" What went wrong?

You're not going to see it. Emacs users don't type or edit text faster than vi-users, they type and edit less text . Its a hard thing to convince someone that Emacs is a better editor, when it's clearly and obviously worse at editing tex
