Yesterday, I was chatting on with a friend in California, and he seemed delighted thet California was no longer on my time (Arizona time). So, I did a couple of /CTCP TIME's one for his machine, the other for mine, and noticed his machine was 1 hour and 2 minuites behind mine. I bemoaned my difficulty in getting NTP to syncronize over dialup connections.

My friend suggested clockspeed, by D. J. Bernstein, available here: http://cr.yp.to/clockspeed.html.

Powernow-k8 with recent versions of Linux 2.6.x

Hi there,

I received my new AMD-64 box last week, and got pretty excited about the cool and quiet feature... Those of you who's got a box running in their bedroom should know why this feature is that cool...

But unfortunately, I found out that due to some broken bioses, the powernow functionnalities are pretty much broken on most mainbords (mine is an ASUS K8V-X).

Even latest bioses can't do the trick.

Today, I got a call from my brother, an un-willing Windows user. He wants me to teach his 12 year old daughter Linux. I'm viewing this as a really good chance to make an impact on someone that is willing to learn.

This evening, I ponder curriculum and course content. Where to start? what to teach? Those are the questions I have.

Pop goes Gmail

I've been looking for a good POP account for quite some time now, and when Gmail notified me they were offering POP access to my Gmail account, I jumped on it, but had limited success until... Well, let me tell the whole story, with some background to start.

My desktop system, a PII-500 with 512 megs of RAM runs Debian Woody just fine, and I like this distro, even though most apps are slightly out of date. I use backports from http://www.Backports.org for those situations where I need something more up-to-date. Especially when it comes to web browsers.

The Term "SwapCached" in /proc/meminfo

I was looking in the rhel-rg-en.pdf Reference Guide, and saw that they defined Swapcached in an interesting way, and then searched on the web for Swapcached, which yielded a bit more, but not a lot. So here are some definitions (which can't all be right):

the 4th number in the version of linux

... let me recapitulate the possible versions of the linux kernel:

the normal kernel26 release is versioned 2.6.x

if something is broken in the release, we simply add 2.6.x.1 to it and hope people do not realize or do realize but use the new one and are quiet

unfortunately this .1 is the same var, as the var that is the marker for another tree of the kernel sources (mm, ck ...), so if you do not use the vanilla kernel, you are "messing around"

Host Configuration:

  • Toshiba Satellite Laptop
  • 512MB RAM

  • VMware 4.5.2

ctrl-alt-delete in Fedora Core 2 GNOME is bad

Submitted by catfeeder
on October 14, 2004 - 11:17am

I recently installed Fedora Core 2 on my work laptop, and I've been pretty happy with it except for one annoying feature. If you hit Ctrl-Alt-Delete while running XWindows (and GNOME), instead of bringing up the dialog asking you if you want to log out or not, you get booted out of X alltogether; as if you had pressed Ctrl-Alt-backspace. This is a *very* annoying feature if you happen to have a lot of stuff (in my case, work related) open on the desktop. It's all gone.

Networked printer

Our Brother MFC 3100c died a little while ago. It kept coming up with "Machine Error 41"

Anyway, that AIO was the only reason I still had a solo winblows machine on my home network. After looking on LinuxPrinting.org I found that an Epson that I liked was supported by gimp-print. Actually the one I was looking at wasn't listed, but since it was just a recently released "upgrade" I figured it should work.

first parts of aio filtered wakeups released

Finally got the aio filtered wakeup code ready, and pushed the first half or third of it -mm -ward. I'm sort of waiting for feedback to come back and so on to tweak it to everyone's satisfaction, and then the code to use current_wait(), current_wait_bit(), and init_wait_bit() for aio that goes atop it can be respun. All this is still not quite enough as the codepaths called from aio contexts need
