Setting Logitech mouse speed

nospam@example.com (Magnus Määttä) — Sun, 20 Jun 2010 16:33:19 +0200

I've a Logitech MX518 and the cursor was moving too fast..
It took some googling before I found out (again) how to make the mouse move slower..

The solution to the problem is called lomoco.



$ apt-get install lomoco

$ lomoco -8

This will make the mouse have 800 DPI resolution and makes it a bit slower compared to
the default 1200 DPI.

I also set USB mouse polling a bit more frequent:

/etc/modules



usbhid mousepoll=5

Updated infoplug 0.3 hack for amarok [1.3.7/1.4.0-svn]

nospam@example.com (Magnus Määttä) — Sat, 07 Jan 2006 05:54:29 +0100

I have updated the infoplug hack some and made patches for amarok 1.3.7 and 1.4.0-svn (current trunk).
I fixed a bug which made it show current time in minutes:seconds instead of hours:minutes:seconds when the time was 60 minutes or more..
Also, Last Played have now been added.

1.3.7
1.4.0-svn

Only 1.4.0-svn version have been tested. Second chunk for app.h is different for 1.3.7 and it applies with some fuzz, hopefully it will compile too! =)

Had to reinstall firewall + workstation

nospam@example.com (Magnus Määttä) — Thu, 11 Aug 2005 17:13:58 +0200

After I upgraded to baselayout 1.12-pre-something on my firewall and workstation, I had to reinstall my machines (using Gentoo). I guess I could have chroot'ed and manually reinstalled a good version of baselayout, but I choose to reinstall my workstation.

The plan was to fix my firewall right after that (I still hadn't rebooted it yet so it was running). Unfortunatley the firewall was rebooted and I had to reinstall that one too since I hadn't fixed so single user mode worked through serial.

So Internet have been down here for a week (I was lazy =).

Reorganizing my webserver [Part 2] - Using mod_vhost_alias

nospam@example.com (Magnus Määttä) — Mon, 30 May 2005 02:43:38 +0200

This is part 2 of my reorganization..
When I was doing all that moving around and stuff, it got out of hands with vhosts for three domains (for now!). So I figured I should take a look at mod_vhost_alias.

After some reading and whining on IRC, I came up with this config which works with my "old" setup (that is, the one I just made a few hours ago):
apache httpd.conf:



<Directory "/usr/local/www/domains/*/*/htdocs/">

   AllowOverride All

</Directory>



<Directory "/usr/local/www/domains/*/*/cgi-bin">

   AllowOverride None

   Options None

   Order allow,deny

   Allow from all

</Directory>

And the vhost stuff:



NameVirtualHost *:80

NameVirtualHost *:443



<VirtualHost *:80>

   ServerAdmin foo-removed@*-removed-*.stoldgods.nu

   VirtualDocumentRoot /usr/local/www/domains/%-2.0.%-1/%-3+/htdocs

   VirtualScriptAlias /usr/local/www/domains/%-2.0.%-1/%-3+/cgi-bin

</VirtualHost>

Here are a few examples what the result looks like:



foo.domain.tld :  /usr/local/www/domains/domain.tld/foo/htdocs

foo.bar.domain.tld :  /usr/local/www/domains/domain.tld/foo.bar/htdocs

foo.bar.baz.anotherdomain.tld :  /usr/local/www/domains/anotherdomain.tld/foo.bar.baz/htdocs

anotherdomain.tld :  /usr/local/www/domains/anotherdomain.tld/_/htdocs

KSysGuard

nospam@example.com (Magnus Määttä) — Sun, 29 May 2005 02:23:00 +0200

Although I have started this little app "by misstake" before, I have really never looked at what it really is.

KSysGuard is a really simple app that lets you monitor one or more computers through a small application called ksysguardd. It can monitor network traffic (bad packets, compressed packets, etc), get information from hardware sensors through lm_sensors and more.

Here's a screenshot of it in action monitoring my firewall and my server.

You can add new sheets to have one for each server, have a process controll table where you can see all running processes and send signals to them.

To use it you can either run ksysguardd as a daemon or start it through ssh (default), rsh or a custom command.

Debian and udev - no go

nospam@example.com (Magnus Määttä) — Tue, 08 Mar 2005 20:35:48 +0100

Today I tried to change my Debian machine to use udev and found out Debian's udev init script or something like that is totally fucked up.

xmms-infopipe like plugin for amaroK

nospam@example.com (Magnus Määttä) — Thu, 03 Mar 2005 19:38:15 +0100

I wrote a small plugin for amaroK today. It works almost like xmms-infopipe, but this one sends data over UDP instead. If you don't know what xmms-infopipe is here is a dump of the data available through my plugin:



Interface: InfoPlug

Version: 0.4

Status: Playing

Artist: charles lester

Title: soul trip

Album: Cannabissimo Electro

Total Time: 5:26

Current Time: 1:10

Genre: Electronic

Year: 2002

Comment: BLA BLA BLA

Bitrate: 192 kbps

Sample Rate: 44100

Score: 0

Play Count: 0

Volume: 82

URL: file:///...../08-charles_lester-soul_trip-bla.mp3

It took me around 12 hours to write it - including the time to relearn some C++, learn some Qt and the amaroK API.

Currently only one bug is known. amaroK will crash at shutdown, I don't know how to fix it
and I'm a bit, uhm, what's a good word for it.. tired.. coding C++ right now. Also, there's no GUI for the configuration stuff and I don't know if I'll ever add it, I probably will. But atleast it works for me [tm]. If you need to change the port or something it's a oneliner..

Here are the files:
infoplug.cpp
infoplug.h
needed.patch

The patch is for current CVS so you might get some fuzz or something for other versions..

Ohh, and remember that my C++ sucks and this was a "quick hack".

Adding KDE service menues

nospam@example.com (Magnus Määttä) — Sat, 19 Feb 2005 00:35:04 +0100

Adding KDE service menues was a bit cryptic, so I made an example..
XMMS enqueue service.

Here is a tutorial (for 3.2 but works with current CVS).

Setting up netconsole

nospam@example.com (Magnus Määttä) — Mon, 01 Nov 2004 00:23:23 +0100

So I tried to boot 2.6.9-mm1-RT-V0.6.2 (link) on my laptop and it hardlocked on boot. And new laptops don't have any serial port, which sucks. Getting boot messages and kernel info is so easy with a serial port available. But since there is none on this one I had to look for another solution, netconsole.

Now, this is how you use netconsole:
Start netcat on the machine you want to log on with:



$ nc -u -l -p 4567

Netcat in my case is nc6 and the port I want to listen on is 4567.

Then on the machine you want to send messages from, use:



netconsole=<src-port>@<src-ip>/<source eth>,<dst-port>@<dst-ip>/<first-router-mac-address>

In my case, I used:



netconsole=1234@10.0.3.6/eth0,4567@10.0.2.1/00:50:BA:C2:11:34

I have netconsole builtin to my kernel on my laptop so I can use it from boot.
If you have no router between the host you're sending your logs to and the one sending them, specify the mac address of the reciving system.
