LTSP | LTSP Client Upgrade

All the following commands are entered on the server. Normally this would be having logged into your normal LTSP desktop and opened a terminal session, but it could equally be from an ssh session to the server. The key thing is that you do not run these commands from a client shell, as the client system is read-only.

Howto | Install Adempiere on Debian Lenny

I have run through these notes again and corrected the odd mistake and they do seem to work. At least until something changes!!

I have not yet got the init.d script working, but am able to successfully start adempiere and reach the login page.

I need to review the postgresql security settings as “trust” for all is probably unsafe.

LTSP | LTSP Server Sizing

RAM

LTSP website recommends 256mb for the core system plus 50mb per user:

Total RAM = 256mb + (25 users x 50mb)
          = 1506mb

However Edubuntu recommends a different formula:

Total RAM = 150mb x 25 users
          = 3750mb

We recommend you choose the greater of the two, and double-it if you can (see update below).

Howto | VirtualBox Mismatch

I have been told that installing package virtualbox-ose-dkms solves all these problems. I have installed and it reported that my modules were up-to-date, which is promising. I shall try and remember to update this page later, but I thought I’d write this now in case I forget!!

Howto | Submit a UK Self-Assessment Return under Linux

Yes once again I come to complete my tax return, last time it was a far from successful experience.

Given that that page is now a year old and my next year’s return is required, I thought it was an opportune time to update it. Unfortunately nothing much has changed, the list of personal tax applications has shrunk, as TaxCalc’s market domination continues. The only Linux-compatible competitor seems to still be ftax and it requires Acrobat Reader, which isn’t available for 64-bit Linux.

Howto | Optimise Firefox

Apparently Firefox uses sqlite for its databases, maintaining several *.sqlite files in your .mozilla/ profile directory. Over time these become cluttered and it helps if you vacuum it:
