CherryBeach Wallpaper

10 January 2015 on Personal Blog


My sister accidentily took this photo on her Nexus 5 phone and it turns out to be quite a good HiDPI desktop wallpaper. The lack of featured highlights and the muted background color does not crowd out more colorful desktop icons. In fact it tends to enhance desktop icon visibility. It is freely available under a CC by 4.0 license. Just right mouse button of the full size image and Save as.

Double Rainbow

1 January 2014 on Personal Blog


Secondary rainbows X are caused by a double reflection of sunlight inside the raindrops, and appear at an angle of 50–53°. As a result of the second reflection, the colours of a secondary rainbow are inverted compared to the primary bow, with blue on the outside and red on the inside. The secondary rainbow is fainter than the primary because more light escapes from two reflections compared to one and because the rainbow itself is spread over a greater area of the sky. The dark area of unlit sky lying between the primary and secondary bows is called Alexander's band, after Alexander of Aphrodisias who first described it.

Fastest Editor

9 October 2007 on Personal Blog

This is how I use my favourite console editor, as an alias in my .bashrc file, and I would suggest it's the fastest and simplest console based editor available... both to type and start, and also to save and quit...

Desktop Snapshot II

26 September 2007 on Personal Blog


Wow, 3 months since my last post! Almost hardly worth the bother but this is a recent desktop screenshot. I just managed to get qemu-kvm (KVM) running a (legit, btw) Windows XP installation and here are 3 browsers, Firefox and IE6 on XP, and my favourite Konqueror, all running at the same time.

Desktop Snapshot I

6 June 2007 on Personal Blog


Here is a June 2007 snapshot of my main KDE desktop using the KDEmod packages from ArchLinux with the Domino theme and Tango icons. The kicker panel at the bottom is set to immediately dissapear so the whole desktop is available to applications across the 4 desktop screens.

Courier authProg

3 June 2007 on Personal Blog

Here is a Bash shell script to handle authentication from the pipe handler for the Courier-MTA authdaemon. See README authlib for more information on how to use it. On a Debian system it is located at /etc/courier/authProg.

Skype on AMD64

3 May 2007 on Personal Blog

At long last, a new skype for linux has been released, albeit a beta release. The ALSA sound system has been improved and now allows for non-standard devices to be used which means far more flexibility when it comes to trying to record skype sessions on linux.

No More Drupal

28 February 2007 on Personal Blog

Well there goes my Drupal5 experiment, too much bother and I really don't get good enough value out of all it's complexity. It's way overkill for delivering a simple blog-like page like this which I now manage using Kate, the KDE editor, along with KDEs transparent inbuilt kio-slave for FTP access.

No More Ubuntu

14 February 2007 on Personal Blog

I upgraded this server from Ubuntu Dapper to Debian Etch because of the /bin/sh -> /bin/dash debacle. Things broke because they decided to change the default shell without ANY warning and no hint that they even care about the problem. Not on folks. I'll still use Kubuntu for desktops but not for servers, ever again. Sure I could easily work around it but I no longer trust Canonical/Ubuntu NOT to pull some stunt like this again in the future so it's back to good old reliable Debian proper for all my servers.

Bluetooth Headset

3 February 2007 on Personal Blog

Here are some notes on how to get a Bluetooth Headset working on a Debian system such as Kubuntu. This particular exercise involved using a Kubuntu Feisty Herd 3 liveCD...

Eternium Remix

23 December 2006 on Personal Blog

This is a remix of Eternium by Michael Walthius using Sonar6 and the default Roland TTS GM sound synth. The actual notes are unchanged from the original but volume settings and instruments have been recreated from scratch for Sonar6/TTS. Mastered in 24bit/96khtz using Sonitus:fx Reverb (Hall mix 10%) and the Cakewalk FX Dynamic Processor (Hard Limiter 7db gain) and then rendered to this 128bit MP3 at 44.1khtz.

A/V Playlist

12 December 2006 on Personal Blog

About time I added something else to this page. Here is a mixed audio and visual old school m3u playlist test. It is simply a mp3 then a mp4 video followed by another mp3 audio file to show a mixed Audio/Video stream. This "trick" no longer works with Chromium but Firefox still allows one to open an abituary application per media type.

Kmix Video Capture

29 August 2006 on Personal Blog


Here is a 1:18 minute quick and simple test MP4 (was AVI) screen capture using Xvidcap. The subject is testing Kmix to get reasonable audio levels from a cheap Creative microphone along with testing line in and wav playback levels through an old SBlive audio card (on Kubuntu Dapper).

Audio Mixer Test

27 August 2006 on Personal Blog

This is a simple 3:44 minute mixer test using arecord and Kmix on KDE (a Linux Desktop) at 48000 Hz, 2 ch, s16le, 128.0 kbit MP3 and 28 Kbit OGG. There are 3 sources into an older Creative Labs CT4760P SBLive! PCI card using the ALSA 1.0.11rc4 EMU10K1 driver. The sources were; line-in from a Foxtel cable TV receiver, a cheap Creative Labs lapel mic into mic1 and a 192khtz MP3 played back via an internal PCM port.
