So, a while ago I started personal logbook and wanted a way to keep those posts off the main blog (while still appearing in the RSS and twitter feeds). Long story short, Blog-in-blog gets a given category off the main blog, and with thinks to the wordpress.org support forum I was directed to the Page Links To plugin, which added the necessary navigational behaviour. Job Done!

I’ve been trying a dozen different configurations of my 2x500GB SATA drives over the past few days involving switching between ACHI/IDE/RAID in my bios (This was after trying different things to solve my problems with Ubuntu Lucid Lynx) ; After each attempt I’ve reset the bios option, booted into a live CD, deleting partitions and rewriting partition tables left on the drives. Now, however, I’ve been sitting with a /dev/mapper/nvidia_XXXXXXX1 that seems to be impossible to kill! ...

**Updates(26/3/10): **Thought I’d give the liveCD another go (this time using the dailyx64 image and using unetbootin), thinking it must be something simple; so during boot i just kept pressing escape, before the splash screen came up. This got me around the splash screen issue and it seems as if everything is fine. Also, I found a matching bug report on launchpad, but no resolution as of yet. Guess we’ll have to wait and see. ...

So in a continuing effort to be more productive, I’m segregating off a section of the blog for ‘My Diary’. I used to keep a diary, which has long since been lost in the ether, and I have been reticent to have too much personal or off-topic stuff on the main page, so why not put it here! Well, we’ll see how it goes.

My lil-NAS has plenty of space but is maddeningly underpowered. I came across a permissions issue where, depending on how the files in question got there, they would not be accessible to my windows boxes because they were owned by root (I have no doubt that its my fault!) So, first attempt was nice and easy. $chown -R smbusr:smbusr * But this was taking a horrific amount of time, so I thought “There must be a better way”. ...

** NS-3 Appears to have a staggeringly steep learning curve so I hope these posts help out someone else (or me, when i forget all this in a month).

I hadn’t used Mercurial before so I thought it might be a good idea to leave a reminder for me and anyone else who comes across it… For tidyness, I do all of my dev-stuff (Subversion, Mercurial, CVS, Git etc) under ~/src and only take root privileges when its needed; any good makefile should relocate the necessary files for you at the ‘make install’ or equivalent point. **Update:**This article was picked up by the guys at DevCheatSheet.com and I’m really honoured to be included in a site that I’ve been dipping into over the years, so if you need any kind of cheat sheet or quick reference, I highly recommend checking them out. Anyway… ...

So, say you have a long list of instruction (like multiple apt-get install lines) and you want to eliminate common words? Easiest way to do it is (assuming you have all of the instrustions in “list.txt”) [FYI the ‘' character indicates a continuation of a single line ] cat list.txt\ | tr ’ ’ ‘\n’ \ #Expands all space characters to new lines | sort | uniq \ #sorts each line, and then eliminates duplicates ...
