A simple matter of…

The last few days I’ve spent playing with Eucalyptus - the open source EC2 equivalent.
Several times I’ve been tearing my hair out - particularly with some image issues (why oh why can’t it use an external database rather than the noddy internal one - that way when it’s confused I can fix it up more [...]

Recently, X.Org has been removing HAL from the requirement list. This is good except that it means reconfiguring things. Again.
I have a Logitech G7 mouse and it has a side button which defaults to “back”. I like it remapped to “middle button” (which pastes text in Unix). I used to use a [...]

I’ve recently changed my laptop and as it’s a small netboot, I’m running Ubuntu netbook remix on it. Today I’ve setup email on it and it’s a little involved so I thought it worth documenting.
First a little background - I run my own email servers and I like using “mutt” as my email client [...]

Today I had my first real trial of Ubuntu netbook remix (9.10). This is an an Eeepc 1008HA netbook.
Netbook remix has a nice “launcher” which takes over the whole screen and uses large buttons. This is great for me as I can’t use trackpads at all The [...]

I’ll write up a bit more in a while on Bitcube, but for the record:

full_scans: 71
max_kernel_pages: 128571
pages_shared: 13640
pages_sharing: 19803
pages_to_scan: 100
pages_unshared: 79285
pages_volatile: 322
run: 1
sleep_millisecs: 20

KSM is “Kernel Samepage Merging” and is a way to share memory between virtualisation instances, thus saving huge amounts of memory. In this case it’s a redhat box and another [...]

Yes, part of the point of this blog entry is to check that wordpress will tweet all my blog posts automatically
Identi.ca is basically an open source twitter, it will be interesting to see where it goes, but ATM at least it can feed twitter quite nicely. Unfortunately I still have to follow twitter [...]

In a follow up from yesterdays entry, I opened up my graphics card (Nvidia 8800GTS) and got rid of the dust. As you can see - there was quite a coating! Shame Nvidia made it so hard to clean (there’s normally a cover over this lot so you can’t see it, or clean it), [...]

Recently my desktop has become a little noisier than usual (it is pretty quiet).
After some investigation I found that the cause was the fan on the graphics card.
Using nvclock you can find out (retrospectively only AFAICT) the fan speed, let’s reduce it to 40%:

sudo nvclock -f -F 40
Current fanspeed: 1612 RPM
PWM duty [...]

Pulseaudio seems to cause many, many problems for a lot of people. Unfortunately that’s partly the nature of audio applications on Linux. Let me explain. Only one program can talk to the soundcard at once - so you can either listen to OGGs/MP3s or get IM “ping”s, but not both. Obviously [...]

I’ve just setup my server at home with a few VTs logged in as root, just makes troubleshooting a little easier. Details are up at:
