Hibernate works again and Network-manager works

I wrote yesterday that hibernate did not work for me in Ubuntu 7.10 (Gutsy Gibbon). The solution was easy, I changed from the closed source fglrx to the open sourced driver ati. After that can my MSI S271 hibernate again.

Information about the bug in fglrx can be found here.

I continue to play around with Gutsy. Network-manager is now working. Entered the configuration dialog and activated roaming configuration and then restarted the networking init-script:
sudo /etc/init.d/networking restart

Unbuntu 7.10 (Gutsy Gibbon) after a week

After have used Ubuntu 7.10 a little more than a week I have got some experiences, bote positive and negative. I have not spend any time to try to fix the problems I have, yet. So there may be solutions to them. The computer I have used Ubuntu 7.10 is my laptop MSI S271 with a AMD-CPU and a ATI graphics card.

Lets start with the bad things. Hibernation have stopped working and I have found on the forums that I am not alone. This is definitely my biggest problem so far.

I got disappointed that I can't use Compiz. It may work if I change driver I have not tested that. Both the new open source driver xgl and the older one may be candidates. Currently am I using fglrx Several sites have written today that AMD/ATI has released a new driver, that may be another solution.

The network manager seems still not working for me, but thats no big deal for me. I can use wireless and it is not to big deal to change SSID and network in the old fashioned way.

Finally I have some problems with pidgin. Groups with Swedish characters like ÅÄÖ are showed two times, on time with correct title and one time with a typical UTF-8 error. The faulty group cannot be removed. I know that I have had the same problem with earlier GAIM/Pidgins after upgrades.

Now its sounds like it is a big disappointment, but its not. The system is still very stable and iot works fine for my daily use. There are some positive changes too.

First of all, which I like very much, is that I get notably better battery time. I have no exact measurements but at least half an hour. Futher, the printing tray icon notifies me when my printer is out of paper. That is good since that I am not always in the same room as the printer. Open office is also starting faster. The good things may sounds like few, but that is OK since Ubuntu is released often and easy to upgrade. Smaller changes gives fewer problems.

Important is also that the upgrade from 7.04 worked smoothly after I had disabled my third party repositories, like medibuntu, and increased the size of my root volume.

Laptop refreshment and Jython

I haven't had too much spare time for a while, therefore the lack of writing. Fortunately I had time today to start upgrading my laptop to Ubuntu 7.10 (Gutsy Gibbon) when it is still fresh. I have a few minutes left until it finished.

Yesterday evening I were at a seminar about Jython. Jython is an implementation of Python that runs on Java virtual machines (JVM). The advantage of this is that you can use all existing frameworks etc that exists for Java but still programming Python. The talk was about a Google summer of Code project that wrote a compiler for Python 2.5 for Jython. Until now Jython had only run Python 2.2 code. There were a lot of talk about how they had written the compiler to Java byte code with a minimal of effort. The focus was to get something working, and the got it.

Swedish police saves 400 cars by using MySQL

MySQL has a press release that tells us that the Swedish police save the amount of 400 fully equipped police cars in the period of five years. Unfortunately, very few Swedish governmental organizations tells the public these kind of facts about their savings using Open Source. I hope this will be a wall breaking case.

Stack traces

We need to learn Java programmers that stack traces are not valid error messages. They should neither write, eventually, extra error information within the stack trace. Please write a clear error message that is separable from the stack traces. The stack traces are OK in debug mode, not in production mode.
