Dell XPS 13 touchpad issue

As I already mentioned in my previous post about the XPS 13, I had issues with the touchpad: it freezes rather frequently, because it looses sync a lot. After losing sync for a few times, the psmouse driver issues a reconnect request. And when that happens, the touchpad freezes.

It looks like this in the kernel log:

Goodbye MacBook Air, hello Dell XPS 13

Many people I know use a laptop for almost anything, anywhere. When they arrive at the office, they hook it up to an external monitor, and use an external keyboard and mouse or trackpad. I prefer to have a proper workstation, with powerful CPU and GPU, lots of RAM and multiple large monitors. As it's rather difficult to take this setup with me to meetings, or when travelling, I still require a secondary device that I can take with me everywhere I go. Some people seem to be OK with a tablet for that purpose, but that just doesn't work for me.

Bbox 2 / Sagem Fast 3464 temperature

As you could read in one of my previous posts, I have been investigating my Sagem F@st 3464 modem a little, to see if it ran Linux (which it does). With the help of this topic, I was able to login into the modem with telnet. After entering the password and typing the "shell" command, I was presented an ash shell with BusyBox.

Whenever I login into a new Linux system, I have the habit of executing the uptime command. Doing that, I immediately noticed a load average of 1.00. So I checked with top, if anything was keeping the system busy. And yes, there is a process tr98* using about 100% of the CPU all the time.

Gentoo, CUPS, HPLIP and HP Color LaserJet 3600n

Somewhere in June 2009, I became self-employed. Since it involves sending invoices, I decided to create a template with OpenOffice. After creating a new invoice, I export it as PDF and email it to the customer. Saves me paper, ink, envelopes, stamps, trips to the post office, fuel, ... You get the picture.

Unfortunately I still have to hand them in to my bookkeeping office on paper, so I still have to print them once. Which is what I've been doing since June 2009. Until I tried printing invoices from Q4 2009, somewhere in December. The printer refused to print anything.
