  1. Re:ext3 options on Linux Filesystems Benchmarked · · Score: 4, Informative

    "I am assuming, or at least it looks like, these tests were run with the default data=journal - so to be fair, they should have been run in data=writeback, or maybe even all three modes. Again, all you have to is specify in /etc/fstab and reboot, no big deal."

    And where do you get the idea that this is the default? According to mount(8):

    This is the default mode.

    What I really would have liked to see on this benchmark is ext3 on 2.6 with dir_index enabled. (Maybe this would also gain the benefit of the Orlov allocator? I haven't been paying attention to what's been backported.) ...In fact, I would have liked to see this whole thing on 2.6.

  2. Re:Spam him back on Stopping Overseas Fax Spam? · · Score: 1

    "fake a bunch of bad transmits and request resends (does the fax protocol even do that?)"

    Yes. In places with crappy lines, it's best to override the speed negotiation and set it to a sane value. (Say 9600 bps if the lines can't handle 14400. These are mildly random numbers because my father does this, not me.) Otherwise the fast line speed, which negotiation accepted because the short test burst worked without error, creates too many retransmits and falls behind on average.

  3. Re:Give it a go. on Gentoo Linux Announces Gentoo Linux 2004.1 · · Score: 1

    "I see now there are binary packages. ... Can I install and use binary packages all the time?"

    Binaries are solely for speeding up installation; you install Stage 3 + GRP (that is, the binaries) and then it acts like a normal source-installed Gentoo system. You can either leave it for a while doing emerge -e world after you finish the install to put your own USE/CFLAGS settings into effect, or just let things get replaced naturally when you update things.

    rac argues for this to continue here; I'm not aware of any other information.

  4. Something I've been thinking about: Wacom tablet on Homebrew Musical Instruments? · · Score: 1

    I've been thinking of hacking up some sort of tone generator to a Wacom tablet, and mapping X to pitch, Y to timbre (or maybe gestures for things like wah-wah? That axis is undesigned ATM), and pressure to volume. Of course, this is all vaporware still...

    I have yet to try gentoo, I tend to like having my distro frozen in time on a set of CD's until I'm ready to jump to the next release (Yes, I build my Slackware ISO's from slackware/current)

    There is no rule that says you must put (emerge sync && emerge -uD world) &>/dev/null in /etc/cron.hourly. Just don't sync, and the software won't upgrade (or want to upgrade dependencies) when you install stuff. They're also working on an "emerge security" feature reminiscent of tracking a FreeBSD release, with only security updates done.

  7. Gentoo + PHP = infinite pain on Build From Source vs. Packages? · · Score: 1

    Sure, like any distro, an install will blow here and there due to dependencies, but, for the most part, I find it rarely happens with Gentoo....and makes the whole process so easy to do.

    You have clearly never worked with mod_php. It likes to install a fresh copy over the old one, install both mod_php and CLI php whether you wanted CLI or not, and then warn you... "Due to previous bloopers with PHP and slotting, you may have multiple instances installed..." They're not too previous if the same thing still happens constantly!

    Granted it's a worst case, but it is pretty awful (and repeatable, and persistent). Maybe nobody's fixed it because they all commit suicide after looking at the tangle of PHP ebuilds?

    "B. ...only bundled as part of, and for the sole purpose of running, your Programs,...."


    Read what you quoted, hmm? $DEVELOPER is granted the right to redistribute Java as part of THEIR Java program; but the people who receive Java in this manner are NOT free to redistribute it. And distributing Java for other reasons, like allowing people to develop in it, is also NOT allowed by that clause. So section B doesn't grant any rights to Linux distros.


    I'm not going to comment on section C because I don't have a copy of the README handy. But I suspect if it was legal to distribute Java as-is, then all distros would do it, perhaps under a separate non-free tree. But they don't.

  10. Instructions per clock is variable. on Intel Plans CPU Naming Change · · Score: 1

    In modern CPUs, IPC depends on the parallelism of the code, hyperthreading, and so on. Take a look at LAME benchmarks sometime: both Intel and AMD CPUs manage to retire the same amount of IPC for that task, so a P4 kicks Athlon butt in direct relation to the clock difference.

    Here's a question for you: a 2GHz chip averages 2.5 IPC and a 1GHz chip averages 3.3. Which is faster?

  12. info is no picnic either on The Command Line - Best Newbie Interface? · · Score: 1, Redundant

    Fire up 'info bash' sometime and have a look around. They split many things according to whether they're Bourne or Bash shell features. I can see where this information would be useful for someone writing portable sh code, but splitting the contents by it is Just Wrong. It should be done by command. Things seem to be split up among too many indices, as well.

    The cvs info page is another horridly designed piece of trash. They may have one index, but you have to use the 'l' command a lot since all the commands (at least) are documented several ways in several places, none of which is ever what you wanted.

    Try finding "GCC options" in the GCC info pages. They're stealthily hidden away under "Invoking", like it's some sort of deep black art to run a fscking compiler. It wouldn't be too hard to find with recursive search.

    Which brings me to my last point: info's navigation is awful. Why can't there be a sane system for it (like pinfo) with Emacs overriding it for people actually using it in Emacs (who would therefore be expected to know the proper commands)?

    I'm pointing this out because a lot of times Linux Oldtimers point people to info, probably without realizing exactly how horrid it is. It is not at all accessible to newbies, and probably should just be chucked in its current form.

    Demand for those backwards-compatible chips is huge. To truly replace the architecture, even with a 32-bit-only version of it, you would have to change the boot protocol, OS, and BIOS as well.

    In that scenario, the problems would be common knowledge from all the returns of the printer. It's nothing like this ninja technology that watches unsuspecting printouts until it thinks it needs to act.

    Should we quit being concerned with spyware, too, since no law says you have to install it? What if there's nothing but spyware, because Palladium has effectively destroyed anti-spyware companies because Microsoft refuses to sign their products? Just because there's no law granting some company or technology a monopoly does not mean it won't happen.

    Something that always bothers me about these articles is that they never seem to specify whether the anti-counterfeiting measures pay attention to the final size of the bill. I imagine Photoshop doesn't, though, because until its printed, it does not know what the final size will be.

    "...or sneaky (pretend it didn't hear you, so you don't know if it's there at all)."

    If a port is stealthed (i.e. using the DROP target) then it doesn't actually hide your system. If there was nothing at that IP address, normally something upstream would send back something like "no route to host" or "host unreachable". A packet to a stealthed port on a live machine just vanishes, but using traceroute can tell people that the network it's on is actually up and reachable. All the stealthing really does is make a portscan take a bit more resources (time or simultaneous connections) because it has to wait for the full timeout.

  22. Cable costs? on Why Hasn't the DVI Interface Replaced D-Sub? · · Score: 1

    You can get a $250 CRT with a D-sub soldered right into it (this was my 17" Optiquest in 2000), or a $500 Mitsubishi LCD (also 17", 2003) with a separate Dsub-to-Dsub cable. If you want DVI for the LCD, it'll set you back an additional $30 for the cable. (Or $70 if you don't comparison shop and just get it from Best Buy.)

    I really would rather have a DVI-only LCD with no A/D conversion circuitry in it at all, but not being a designer of such things, I don't know how much it would actually save. Demand probably isn't all that great either.

    Generally people are intelligent and creative, despite thinking in so many different ways. They just have no concept of what's possible or impossible with computers, nor any idea of how to do some of the possible things, nor a sense of whether they'll "break" it by doing something. All this greatly hinders their proficiency. A good UI design can alleviate a lot of work of memorizing the mapping between task and command sequence.

  25. Embrace the patents! on Perens on Patents · · Score: 2, Interesting

    Open source must embrace patents in the same way that the GNU GPL embraces copyright. With this, we could force closed-source development houses to fund open source, because the license is only free to other open-source projects.

    What harm would there be in creating such a license? It would give Red Hat a graceful way to keep their promise that their patents would never be enforced against Open Source, and give the rest of the community a collective defensive patent portfolio.

    The harm in not creating such a license is pretty clear; the article is one possibility of the extension of current practice. Another more immediate and likely scenario is that OSS could become a de facto R&D lab for Microsoft. We're already seeing that occur with XUL (or libglade, which is pretty similar) and XAML.
