    Watching a directory tree or mount point is possible with the new fanotify API. You define a mark -- from the looks of it, basically a pattern against which events are matched.

    This wasn't possible with inotify for an arbitrarily large number of files -- anyone who tried will remember inotify has to recursively scan and registers all files first.

    gimme_filesystem_changes_since_i_last_checked() isn't done because that would require the kernel to keep a list that may grow arbitrarily.

    That's why people have focussed on making very fast Javascript engines over the last couple of years -- to enable stuff like this.

    You are asking artists to produce without any external incentive. Basically you want communism -- everything should be shared, and everyone will get everything.

    Communism works in small groups, that's why it's applied in families. But you can't force it on the whole world, saying everyone who doesn't give away stuff is greedy, and argue that taking away their works is justified.

  5. There are a couple of forks apparently. Why does this have to be one monolithic library?

    For this reason, several alternative C standard libraries have been created which emphasize a smaller footprint. Among them are Bionic (based mostly on libc from BSD and used in Android[14]), dietlibc, uClibc, Newlib, Klibc, and EGLIBC (used in Debian, Ubuntu and ArkLinux).

    Obviously it's pure speculation, but I have a hard time believing this would mitigate any punishment Bales receives. It would be a nightmare of the most extreme order for the military should Bales be exculpated, even in the most limited sense. The Afghans have been screaming for him to be tried under Afghan law. It would be hard enough to punishment short of the death penalty to the Afghan public, much less an outcome that ends with him in psychiatric care first. This is just one more massive headache in a case that can't be over for the Pentagon fast enough.

    That's what I think. They will search through all possible excuses and then declare him mentally ill -- I mean, who isn't mentally ill if they kill 17 people. It's like medication ads today ... look long enough you'll find something wrong. That's no punishment.

    It would be interesting to know what Afghans think about the payment per injured/dead -- how does that relate in their culture?

    It increasingly seems that no one is winning from this war.

    Nobody ever wins in wars. It's about finding out who loses less.

  8. Re:Interesting read on Why Hubble Broke and How It Was Fixed · · Score: 4, Informative

    I wanted to joke about the PhDs getting drunk at their desks, but there are a couple of gems in the text:

    "I saw this guy, Richard Feynman, who was a review board member, take a piece of rubber O-ring and put it in his icy water on television, and showed that it stiffened up. So immediately I said, 'Oh, that's the technical problem, they didn't do the O-ring well.'"

    "That was nuts," Pellerin says. "These guys understood the O-ring, but I put that story in my head because technical people look for technical answers. I never read the conclusion of [the review board] report that said it was a social shortfall."

    We see this very clearly when discussing evoting.

    Then towards the end there is an interesting analogy of the Shuttle accidents with a Korean airline company having an extreme crash rate, referring to people put under too much pressure, and irrational .

    "There's a bunch of research I've come across in this work, where people say that the social context is a 78-80 per cent determinant of performance; individual abilities are 10 per cent. So why do we make this mistake? Because we spend all of these years in higher education being trained that it's about individual abilities."

    It's actually a good read for people interested in managing.

    That's what I would like to know! It was unfortunately upheld in Germany, citing that it takes effort to come up with technical software solutions (i.e. having ideas is hard), that's why there should be software patents. Perhaps I remember incorrectly.

  12. Re:Wake me on Go Version 1 Released · · Score: 2

    What's the point in that? Go is very expressive. Just write in Go instead of Python.

    Yes, because all libraries in the world are already written in Go and everything is better in Go than in any other language in the world. You must only work on trivial problems if you don't need other packages / shoulders of giants.

    Wake me when it has supports seemless integration into Python like Fortran and C (with ctypes) -- then I might consider it for coding CPU-intense stuff. It's supposed to be as fast as C with better syntax, isn't that the point?

  14. Re:Visual slashdotting. on Mozilla Releases HTML5 MMO BrowserQuest · · Score: 2

    I'm waiting to see someone explain WHY, for the love of Pete why?

    To show that you don't need Flash to build realistic games. And open-source it as an incentive to companies to adopt free technologies -- that's the point of Mozilla -- open the web.

    with ALL the trouble Mozilla has had lately, declining share,

    The share has not been declining, actually growing in absolute numbers. The total number of web users is growing all the time. Mozilla isn't terribly worried if other open web browsers gain more share -- as long as there is a diverse market, it's good for the open web.

    practically zero adoption in the mobile space

    They are working on that -- the recent announcement on adopting H.264 made it clear that they take it seriously.

    , the well documented problems with memory leaks

    Not sure if you refer to the newest version. They have the MemShrink team. Allocating a certain portion of memory for caching is not a leak though.

    , extensions getting killed by version jumps

    Not true any more -- my extensions get automatically extended to the newest version by a bot, unless incompatibilities are found. This point became invalid last year.

    , extensions making the leaks worse

    There is little Mozilla can do about 3rd parties, except to put warnings out -- which they do in their wikis.

    , why are they wasting resources making a fricking browser based MMO?

    Mozilla is not a company run for profit. Different people have different interests and ideas of how to progress web development. If someone takes his time and thinks that's a great project, then good for them.

    The pie is not limited.
