powertop

Powertop is a command line utility to help you to reduce power consumption on linux laptops.The tool is written by a guy from Intel, so it probably only works on intel chipset based laptops.
I have a Intel Centrino based Thinkpad T42 so I thought I’d give it a go. If you use linux on [...]

Jabber messages in your dwm status bar

One of the features of dwm is that whatever you pipe into stdin ends up in the status bar at the top of the screen. I thought this would be a great way of getting the last message from a jabber chat onto the screen.
There aren’t really a lot of examples of how [...]

dwm

dwm is an interesting little tiling X window manager. It’s made by the suckless.org people who pride themselves on small useful programs that won’t bloat and bloat over time. This attitude about making small succinct programs is very much in line with my attitudes to programming.
Anyway, I’ve tried lots of alternative X window managers on [...]

cloning linux and the missing eth0

To save some time today, I made a clone copy of an existing Slackware 12.0 installation. I basically booted the Slackware 12.0 host from a Slackware install CD and then did a tar to tar copy to an external USB drive. It all went pretty well. I set up lilo on the new disk and [...]

A decent linux command line SIP softphone

I’ve recently jumped on the VOIP bandwagon. Sure I’ve played with Skype and the voice quality is generally very good, but SIP based stuff seems to be a lot more flexible and interesting. I’ve signed myself up with a SIP provider and also have a work Asterisk server I can make calls through.
When I first [...]

synergy glitches

Since my last post I’ve been continually trying different distros at home trying to resolve my synergy glitching problem. The symptom is simply that the mouse freezes on my T42 for a few seconds and then comes good. I use my old Thinkpad 600x as the synergy master, the T42 is to the right of [...]

slackware to debian

OK, so I have a low level of patience. My T42 now has Debian Etch on it. That glitch I was experiencing with slackware 12.0’s Xorg and synergy2 was annoying me too much … so out went slack 12 and in went Debian Etch. The glitch is gone. I already run Etch on my [...]

Installing chrooted debian etch under slackware 12.0

OK, so now that I’ve installed slackware 12.0 on this TP600X I was thinking about how I might get on if I converted my T42 back to slackware. Surely there’d be a heap of packages I’d miss. Sure I could compile from source. I used to do that years ago when I ran Slackware on [...]

Converting a tcp client program to SSL

Recently I updated a usenet client program I’d written to use SSL. The usenet NNTP protocol has been around for a very long time, and is a very simple text based protocol. The program I had is written in C and simply opens a tcp client socket to an NNTP server, promotes the socked to [...]

back to slackware

I’ve been running Archlinux on two machines here for quite some time now. As per my previous posts, I was starting to get tired of the relentless updates that Arch has. One of my Arch machines is my Thinkpad T42. The other is my old Thinkpad 600X. The 600X is quite old and Arch has [...]
