   I was expecting to read about drives being bricked by buggy firmware. I guess they finally solved the firmware side.

   I didn't get the joke. I headed over to wikipedia to confirm that Knuth was not dead.

   Good idea. It seems like it should be possible also to do something similar with ImageMagick.

   It's doubtful that schizophrenia is all nurture, but it seems conceivable that coercive circumstances could aggravate a case of schizophrenia, taking a subclinical case and making it floridly symptomatic. Coercion could possibly tip

   I don't think C is bad for optimizers. What language consistently generates faster machine code than C?

   This is not hard to understand: a wobbly line is longer than a straight line. That's all.

    Peer review isn't such an efficient process. There is lots of evidence of this.

    It would probably be infeasible to judge every single paper purely on its merits. Reputation may be an imperfect proxy for merit, but it's certainly not worthless. In any event, this argument is there and needs to be taken seriously.

    That is neat and a lot easier to understand than the original link. All the notation made my eyes glaze over.

    I didn't know you could put the redirection first. You learn something new every day. Maybe that form would make it more mnemonic for some people, because it more resembles a pipeline.

    If you're going to write shell scripts or do anything sophisticated with the shell, it's worth understanding the difference. And there is a fundamental difference. With |, standard input is hooked up to a pipe. With <, standard

    Like a lot of people, he overuses cat when it's not needed. `cat FOO | more` is approximately equivalent to `more < FOO`, except the first one spawns an extra process for no reason.

    I'm thinking about how I'd implement CHM. I think I'd use a union-find data structure to generate the acyclic graph, as in Kruskal's algorithm. This would fit into an N-element integer vector. After finding the acyclic g

    At some point the cost of scanning a long file will overcome the cost of doing log(n) seeks. On short files, it really doesn't matter what you do, searching will be fast regardless.

    I never tried adding . to my CDPATH, but it makes sense.

    You don't need to know the number of the line you're looking at. You jump to the middle of the file , and you compare the nearest line to the search pattern. Then you recurse on the top or bottom half.

    The interesting use case for me is that you can make a sorted index and look up records efficiently, i.e. within a script. It works with ctags indexes, for instance.

    The interesting thing about look is that it uses binary search, so it is much faster.

    I made something similar to that. I also made a couple other scripts to help with navigating deep directory subtrees: "cdup" would jump to the specified ancestor directory of the CWD. So from /a/b/c/d/e, &

    CDPATH is kind of obnoxious. It's confusing to have phantom subdirectories no matter where you are, which interact with auto-completion, and they can alias real subdirectories, which is always surprising and annoying when it happens. F

    I have Page Up and Page Down set to cycle through the directory stack, so they are similar to the back and forward buttons in a web browser. Except that mine is circular. I can't take credit; I found the idea on the web somewhere and m

    I think most applications could be sped up significantly by rewriting them more efficiently in their own language. You're rarely maxing out the possibilities of the language you're using, because it requires time, skill and a diff

    If someone really doesn't want to work, then they're probably not going to make a very good worker. Why force them to get a job if they're going to be a drag? I think the vast majority of people want to work just to keep busy

    I think I agree. PHP uses ., and I can't recall ever having a problem with that. However, I've been bitten by +.
