  1. Re:Sure ... on First Look at Sony's Tiny Vaio UX180p · · Score: 1

    Your question makes me wonder...

    How long before we see a consumer product like this, supporting Linux from the beginning? I really need to replace my old and busted notebook, but is nearly impossible to find one, here at Brazil, that fully supports any flavor of Linux and even harder to find one that comes with Linux pre-installed!

    I don't have any use for Windows... why should I be forced to buy it when I get a new notebook?

    Well,

    At first we had issues with the IMAP access, it was too slow, we thought that it was because of the authentication backend... but in the end was because we set a low limit on how many IMAP processes should be spawned by the cyrmaster. We removed the limit, and the IMAP became blazing fast.

    But, we still had an occasional slowdown. It turns out that the HORDE groupware we're using to provide webmail was not designed with performance in mind, so when you throw lots of requests at it, the database backend is flooded with tousands of queries. It happens because when you do anything inside Horde it has to do some sort of query... So, MySQL was handling about 1000 queries/s!

    Solution? Split the critical services among several servers...

  3. Re:Mainly a cure for bad software on An Overview of Virtualization Technologies · · Score: 1

    Sometimes is just easier to pinpoint problems when you have an isolated environment, running one, or only related services.

    For example, I had lot's of headaches tunning a mailserver running a PostFix+Cyrus+Ldap, plus Apache+PHP+MySQL+IMP webmail. We started with 3000+ users, and it was everything ok until we reached 8000... then all sorts of performance issues appeared, an we could only understand what was going bad when whe isolated the services on separated machines.

    A virtual machine is a nice way to do this.

  4. Google Processor on Google Moves From Search To Inventor · · Score: 1

    If Google's need for server is as big as it appears, it makes sense to design and build custom servers for themselves. But my gess is that they'll be following the Sun Niagara architeture, with multi-core/multi-processor designs.

    My point, Google doesn't need raw performance, they need an architeture that scales well, supports lots of concurrent requests, and consumes very little power to make cluster mantaining costs less expensive. Well, thinking this way, at this point it looks like Google might buy Sun to get their Niagara processor ;-)

    In the end, I don't think such a processor would be seen on a desktop computer.

    How many of the average users out there know how to do a simple thing, like install a printer? Or how to keep their Windows up to date? Or how to keep it free from virus, trojans, spywares, etc?

    How can packaging be such an issue for the commercial vendors, when huge projects like KDE, GNOME, PostGres, MySQL, etc... manage to have packages for all major distros? I fail to see how hard is to mantain build scripts for RedHat, Suse and Debian boxes to automatically generate RPMs, DEBs and Tarballs.

    I think that the scenario is pretty much defined, we have the RPMs for RedHat/Novell based distros, DEBs for Debian and it's offspring, and TGZs for everybody else.

    You can build the environment as safe as it gets... but if you can't enforce a secure behavior to your user, you can't be 100% secure.

    Also, management end doing poor decisions based on the average user skills, like using Windows desktops ... or won't bother doing some sort of training to ensure that the users knows the security policy.

    The average user must understand their role within the security plan, understand that good security has much more to do with good pratices and habits than with anti-virus software.

  12. Re:Windows applications too? on Sun's Global Desktop Released · · Score: 1

    Probably the same way NX does.

    It tunnels VNC or RDP connections, adding it's own compression to these protocols, this way you connect to the NX/SGD server on an specific port, and then it redirects your connection to the VNC/RDP server machine.

    But I guess you get better performance from X11 based applications, because X can do caching of bitmaps, drawing primitives, and a lot of other smart things that VNC and RDP can't.

  13. The bliss of module-assistant on Looking Forward, Ubuntu Linux 6.06 · · Score: 1

    I really don't know how your boss did it, but debian-based distros really make it easy to add new modules to the current kernel!

    * There are source packages for these extra modules
    * The source packages point to their build dependencies (apt-get build-dep)
    * A minimum build system is an apt-get install build-essentials away from you
    * Nicely packaged kernel and kernel-header packages

    AND, there is also module-assistant, a script that will make the whole process automatic to you! It checks if your system is ready to build modules, downloads and install the required packages, presents you an updated list of avaliable modules, downloads, compile, install and loads them for you!

    I'll never touch a RPM based distro again! APT and DKPG really make my life easier =D

    (4) "MySQL is free" * Only if your application which links against the client library is also GPL. Myth used to scare people away from opensource GPL code.


    It also means that the only code on your application that needs to be GPLed is the one that talks to the database. I usualy never talk directly to the database anyways, so this is hardly an issue to me.

    Look at the bright side, at least it will force you to decouple your application from the data storage. I know that this may not be possible for some applications, but nowdays I guess most applications that deppend on a database for data storage are Web-based... so deattaching them from the database can do only good =D

    If you want to pay for it, yes.

    Right now I'm having a major trouble trying to migrate a mail server from RedHat7.x to Debian Sarge because the mailboxes are stored at Symetrics EMC Storage unit, and they offer support to RedHat and Suse. We tried to get an answer from the vendor, to see if they could support Debian also, but in the end it took soooooooo long that the old server went down, and in order to keep the mail service up we instaled Debian anyways, and used an open-source module for the fibre-channel card.

    Also, if you want to use Oracle on Linux, and keep their full support, you must use RedHat or Suse. You can run Oracle with Debian or Gentoo, but if you do that Oracle won't give you support...

    So, the bottom line is: if you want to buy, only RedHat and Novell are selling. But if you want everything for free, you can get from anyone.

    IIRC, file locking is a feature implemented only by Windows, and it's a major PITA... It's what forces you to reboot on every OS update, because the OS won't let you write or replace files that are open or being executed.

    On UNIX file locking is implemented by the use of lockfiles... and only where it really matters. If an application needs lock on a file, it writes a .lock file to a pre-determined location, and every other instance of the aplication checks if this file exist in order to know if they can open it.

    UNIX behavior is nicer, because if some random process acessing a file locks-up, or enter on an infinite-loop, or anything else... you still be able to acess, modify and remove the files...

    And, as a matter of fact, if a document needs to be acessed by more than one person at once, you should implement some kind of versioning system... or use a WIKI!!!
