  1. Re:XFS for huge mailqueues, otherwise EXT3 or EXT4 on Ask Slashdot: Best File System For Web Hosting? · · Score: 1

    it doesn't take a huge hit listing e.g. 4k files in a directory anymore.

    Umm, maildirs store each message in its own file. I clean up (archive) emails from each past year in a separate folder and still easily have 8k files in each... and that is not my busiest mailbox.

    After a few thousand items of anything, the proper tool for the job is a database, not a file system. Though file system can be described as a kind of database, any in case there are problems common to both, such as fragmentation, a specialized data storage always beats generic ones. Personally, I like what Dovecot does - maintains a mbox-like structure ("old-fashined", all messages from a single mail folder in a single file) which is also padded appropriately so fields can be updated without rewriting the file) and builds an index file on top of it to enable efficient random message access. In this way you get efficient, big, append-only data files, and small, easily cacheable index files: win-win.

  4. Re:Floods on Tech Manufacturing Is a Disaster Waiting To Happen · · Score: 4, Insightful

    HDD prices are now higher providing an incentive for another player to enter the market with manufacturing outside that geographic area (or one of the existing players to bring up some manufacturing there).

    Higher prices make is economically feasible especially considering the payoff bonus of that region gets flooded again.

    ...except if you have external factors such as patents which effectively prohibit anyone truly new entering the industry ever again...

  5. Like "Bibles for Haiti" on OLPC Project Disappoints In Peru · · Score: 3, Interesting

    The OLPC project was always one step near the infamous "Bibles for Haiti" project - a condescending view that an "easy answer", one which is easily mass-manufactured will miraculously solve a hard social problem. That the OLPC-ers are technocratic instead of theocratic makes little difference with regards to the efficiency of the approach. What *should* have been sent are *teachers*, but it's much, much harder to send teachers into the wilderness when they are already so lowly regarded in the western world.

  8. Re:Agree on Does Outsourcing Programming Really Save Money? · · Score: 3, Interesting

    ...The biggest problem I have run into is cultural, you'd have better luck getting someone to work in Green Bay during a Packer game in the US, than you would during a hockey game in Canada. Also their sense of urgency is much more "American rural north" rather than "Manhattan" so there are occasional mismatches in expectations.

    Hmmm, you do realize that outside the western US, Germany, Japan and some other uptight countries, this is actually the "normal" way of life for the largest part of the world? Some call it "quality of life".

    Most of them seem to be drunk most of their "off" time so good luck with oncall.

    This may or may not be true. In France, people drink wine almost like water. Germany and Belgium are known for their beer. Scandinavian countries' weekeend passtimes is drinking any alcohol they can get their hands on, so would you call all of them "drunks"? Again, this labeling thing mostly seems the problem with the uptight and stressed out USians - the rest of the world works just fine as it is.

    I concur - they have some amazing things done in their research division but they seem to follow the footsteps of the famed Xerox Palo Alto center - they can't seem to build products on top of that research.

  13. Re:The Black Death isn't coming back on Scientists Sequence Black Death Bacteria · · Score: 1

    The Black Death could have been stopped in its tracks if those 14th-century peasants had even an inkling of the basic medical/sanitation knowledge that even the biggest idiots among us know today. Basic stuff like "Wash your hands regularly," "Cover your mouth when you cough," and "Don't let your goddamned flea-infested farm animals wander around through your living area, moron" are surprisingly recent bits of common sense that the developed world today takes for granted. Of course, there are still some third-world shitholes where people think that a witch-doctor rubbing feces on an open wound will ward off the evil spirits. But even those places usually have a FEW among them with some basic sense (and soap).

    Unfortunately for the peasants and the third-worlders, there are some huge technological prereqisites:

    • You need clean water to wash hands and wounds with - the majority of surface water in "black africa" is contaminated - not by Evil Western Chenicals but by feces and germs
    • Covering your mouth when caughing is well and good but to have any resemblance of general care and isolation (i.e. hospitals) you need something to cover your mouth *with*, ranging from clean cloth (see previous issue) to gauzes, bandages and sterile equipment
    • Animals in Europe were in houses often for very simple reasons: a) they are warm (remember, the "warm Europe" trend basically started with the 20th century) and b) that was the only option to keep them away from thieves

    Basically, I agree with you, but want to emphasize that the ideas need infrastructure.

  15. Re:Who cares? on Cheap GPUs Rendering Strong Passwords Useless · · Score: 3, Informative

    Technically, MS *did* use a valid and acceptedly secure hash functions, DES and MD4. The problem is that, because of backwards compatibility across their 20-year product spans, they were not as vigilant in updating the protocols. Even when they *did* upgrade them, they went to MD5 (with NTLMv2) - which was again proced weak - but they continued to use the older protocol which allowed trivial attacks.

    Which is why anyone "worth his salt" will laugh if you propose a crypto system which is supposed to last 20 years and is not flexible in its choice of component algorithms.

  16. Go for it! on The Petition to Classify Wikipedia a "World Wonder" · · Score: 1

    This is important in so many ways - including recognizing a genuine, but virtual, "cyber" entity as worthy of being named a "world heritage site". I'd think that Slashdot, as one of the pioneering forums would welcome this.

  18. One trick pony on RIM Collapse Beginning? · · Score: 2

    RIM was a "one-trick-pony" company in a world where people needed the functionalities they now get from "ordinary" smartphones but which the telcos and phone manufacturers refused to provide. If iPhone and Android didn't happend when they did, I would probably own a Blackberry now simply because nothing else did Internet and e-mail decently, but they tried to milk that platform without innovating for far too long. They may or may not be in trouble right now but in 2 years - who would want to buy a new Blackberry?

    It's easy to be prophetic after the battle but imagine if RIM made the first Android phones instead of HTC - they would be unstoppable now.

  19. Re:Not specifically due to GPLv3. on Apple Remove Samba From OS X 10.7 Because of GPLv3 · · Score: 2, Interesting

    And thus the tenets of Free Software relating to code availability and reusability are served with GPLv3 ... not!

    With GPLv3 it's an all-or-nothing situation: either the whole world will use Linux and be strictly copyleft, or it will avoid it and companies will reimplement the parts they need in a way that's more closed than before. That is why GPLv3 is a mistake.

  20. Selection bias on Tech Expertise Not Important In Google Managers · · Score: 1

    I'm not saying the findings are not true, but to verify them they will have to do the same research in another company where tech expertise is completely absent from managers and cannot be relied on by employees. In other words, it may be that at Google it's taken for granted and as such is not noticeable. (even so, it will probably never enter the top 5 characteristics, it just won't be the last one).

  21. Jon Postel on Timezone Maintainer Retiring · · Score: 4, Interesting

    I believe something similar happened when Jon Postel signed off (http://en.wikipedia.org/wiki/Jon_Postel). For a while, he *was* the IANA.

    You know your technology has stopped being a frontier when pioneers like these get replaced by commitees. Globally, it's not necessarily a bad thing, just a sign of times.

  22. Re:Don't make me laugh! on MPAA Threatens To Disconnect Google From Internet · · Score: 5, Insightful

    Unfortunately... probably not. As much as I'd like to see Google launch an "the end justifies the means" campaign and crush MPAA, after some thought I got pessimistic about the prospect. Though theoretically Google could maybe buy all MPAA members one by one, Google is "new money" compared to it and the battle would be far, far from easy and predictable. After some amount of $$ it matters who you know, not how much you have.

  25. Re:These documents should not be released. on WikiLeaks Under Denial of Service Attack · · Score: 1

    These cables, on the other hand, are strategically damaging the U.S., its interests, and its allies. Wikileaks should be exposing corruption, wrongdoing, and illegality. It shouldn't take what appears to all outside observers as a vendetta against the U.S.

    Like 99%+ of people who read this, I have no idea what you are talking about. Care to give an example? You don't need to directly quote a document, but you will need to write enough details so someone who is an impartial observer (simply because he has no detailed knowledge of whatever's going on in there) can reach a conclusion.
