squeezing the slugs

Debian 6 (squeeze) has been the current stable version since February 2011. The latest version (6.02) was released in late June. I have put off updating my slugs from lenny (old stable) for a while because I wanted to see how others faired before committing myself. Indeed, initial reports on the debian arm list indicated …

wordpress setup

I have just added a couple of new plugins to this blog and tidied up some old cruft that I had been meaning to get around to for a while. One of the plugins I have added is a really rather good statistcs tool called Counterize II. It provides a very quick (and impressively comprehensive) …

a graphical web of trust

I recently stumbled upon sig2dot, a gpg/pgp keyring graph generator. In fact this seems to have been around for some time, but I’d never come across it before. It can be used to generate a graph of all of the signature relationships in a GPG/PGP keyring, and, like other visualisation tools, this graphical image producing …

update to autossh – or how ServerAliveInterval makes this unnecessary

I had a couple of comments on my earlier post about autossh which suggested that I should look at alternative mechanisms for keeping my ssh tunnel up. Rob in particular suggested that setting “ServerAliveInterval” should work. Oddly I had tried this in the past whilst trying out various configuration options and I swear it didn’t …

autossh – or how to use tor through a central ssh proxy

Since I first set up a remote tor node on a VPS about this time last year, I have played about with various configurations (and used different providers) but I have now settled on using two high bandwidth servers on different networks. One (at daily.co.uk) allows 750 Gig of traffic per month, the other (a …

email address images

Adding valid email addresses to web sites is almost always a bad idea these days. Automated ‘bots routinely scan web servers and harvest email addresses for sale to spammers and scammers. And in some cases, email addresses harvested from commercial web sites can be used in targetted social engineering attacks. So, posting your email address …

ubuntu 10.04 – minor, and some not so minor, irritations

If and when the teething problems in 10.04 are fixed and the distro looks stable enough to supplant my current preferred version, I will be faced with one or two usability issues. In this version, canonical have taken some design decisions which seem to have some of the fanbois frothing at the mouth. The most …

webDAV in lighttpd on debian

I back up all my critical files to one of my slugs using rsync over ssh (and just because I am really cautious I back that slug up to another NAS). Most of the files I care about are the obvious photos of friends and family. I guess that most people these days will have …

unplugged

My earlier problems with the sheevaplug all seem to have stemmed from the fact that I had installed Lenny to SDHC cards. As I mentioned in my post of 7 March, I burned through two cards before eventually giving up and trying a new installation to USB disk. This seems to have fixed the problem …

psp video revisited

image of handbrake gui

I last posted about ripping DVDs to PSP format back in November 2007. Since then I have used a variety of different mechanisms to transcode my DVDs to the MP4 format preferred by my PSP. A couple of years ago I experimented with both winff and a command line front end to ffmpeg called handbrake. …

plug instability

I’m still having a variety of problems with my sheevaplug. Not least of which is the fact that SDHC cards don’t seem to be the best choice of boot medium. I have had failures with two cards now and some searching of the various on-line fora suggests that I am not alone here. In particular, …

from slug to plug

image of sheevaplug

Well this took rather longer than expected. I intended to write about my latest toy much earlier than this, but several things got in the way – more of which later. About three or four weeks ago I bought myself a new sheevaplug. The plug has been on sale in the US for some time, …
