Just upgraded to trusty tahr

Last time I tested trusty tahr XFCE was not behaving correct. They released it a day ago, and I upgraded few of my machines at home. Everything worked great. As far as desktop, for me there weren’t that much changes. XFCE still works.

The set back I noticed was not due to ubuntu but due to the incompatibility of the bitcoin client. The bitcoin-qt program depends on libdb4.8 and boost 3.1, which are not part of ubuntu anymore (and most likely debian). So it seems that the ubuntu maintainers removed it from the distribution for that purpose. People on the forum were reasoning that the PPA maintainer doesn’t have time and he’s only one guy. I don’t think the guy can do anything if the dependencies are not there, I also don’t think that ubuntu distribution will accept a statically linked version of bitcoin-qt.

May be bitcoin should move the standard wallet to another format, which is not dependent on a certain libdb version. May be an XML format with the wallet encoded as hex strings.

Your work around: Download the statically linked version from the bitcoin.org website.

Eclipse kepler

I downloaded eclipse kepler today and tested it on my laptop.

Improved things:

  1. Memory usage is much less, and the IDE is more responsive. Juno was already good, but kepler uses even less memory.
  2. Highlighting the token under the cursor used to hang in Juno. Now it works without hanging in kepler.
  3. Javascript editor is improved. Some auto completion is implemented when ctrl+space is clicked.

Things that did not get fixed:

  1. Auto format on save for javascript still does not work
  2. The javascript formatter is still way behind the java one.

I didn’t test any JEE like JSF or JSP features. I also was not interested that much in HTML5 editing, even though I think I will try soon.

More on raring, gdm lxdm wdm srim, which one works

lxdm doesn’t work with mate. Once you select mate and try to login nothing happens. When I switch to a text console and do ps -ef | grep session it seems that there is no session running. wdm logs in fine, but sound does not work and the network applet appears as if there’s not network, but actually network is working.

gdm works fine and the other services work as well. I didn’t test lightdm but I don’t like it because I feel it is slow.

Ubuntu raring 13.04 maven error broken package

It seems that ubuntu raring 13.04 was released with a packaging problem in maven. I upgraded my home computer desktop quantal 12.10 to 13.04 raring and other some regular issues, which I usually solve by apt-get -f install, I got an error while installing maven. It seems that maven depends on both libwagon-java and libwagon2-java and both contain the same jar file. dpkg then will issue an error and stop.

By doing some search I found a page on launchpage with the error report: https://bugs.launchpad.net/ubuntu/+source/wagon2/+bug/1171056

I forced the installation of libwagon2 using dpkg -i –force-all /var…. and it worked. However, I know that now when one of those two packages gets removed the jar will be removed as well, and then I will need to purge then package then re-install it.

Final java dev environment

I’ve been going back and forth between IntelliJ’s idea, netbeans and eclipse for java development. I was able lately to setup eclipse with all the features I need, and performs all the compilation function required including pulling maven dependencies and hot deploying jetty’s code on save and the best thing was the ability to edit it’s colors using the CSS provided.

How to do that:

1. Using git clong jBug from http://github.com/mibrahim/jbug.git
2. Inside there, there’s a directory called “settings” in which there are two files: preferences.epf (which includes the editor settings and color theme) and e4_default_gtk.css and that will set the color and font sizes of the tabs.
3. Copy the css file over your eclipse/plugins/org.eclipse.platform_4.2.1.v201209141800/css/e4_default_gtk.css

For plugins, using the market place add the following:

1. egit (to integrate with git)
2. Run-jetty-run, will use in-place deployment with jetty and will close and open the handlers and contexts if you change any of your classes or their dependencies (excellent work)
3. m2e for maven
4. Eclipse color theme. In case you wanted to change the theme edit the wombatcss.xml then import it.

Since eclipse is not a limited edition as idea, you will be able to edit jsp and other files that you won’t be able to edit in idea. It is also much more efficient in terms of memory usage than netbeans and does not block or stop erratically like netbeans as well.

Back to netbeans again after intelliJ misrepresenting compilation

So IntelliJ says it compiled successfully a project. However, when I execute maven jetty plugin to run a small web project, I end up with jars not being found. So what does it exactly mean when IntelliJ says compile successfully ? It seems that it just compiles them, and it really does not make any difference whether you compile or Make the project both cases will result in missing jars if you run the project using maven jetty plugin.

There’s lots of crap in netbeans however it seems to be the only edit that does what it says it’s going to do in terms of maven compilation. It sill suffers from some issue like for example you won’t be able to disable tests if you compile with dependencies.

For the time being I have to accept the flaring white colors of netbeans until one day I can figure out a more consistent way of configuring it.

Finally a driver that does not crash for 82845G/GL

Finally found a solution for a dinosaur machine Dell GX260 graphics driver issues. My lspci shows this:

VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01) (prog-if 00 [VGA controller])

As a plus, I found that compiz works. Hopefully wayland will work as well once released.

Where to get it from? install the drivers from this PPA: https://launchpad.net/~glasen/+archive/intel-driver . I’m running ubuntu 12.10 so that’s what my tests are based on.

Threw in the towel for using netbeans

I admitted defeat in using netbeans for doing anything useful. I tend to waste my time trying to fix the colors so that I can read the code, and that if I didn’t get totally frustrated from simple actions not happening as expected. Simple things like dependencies between maven modules should be happening automatically. If you used intelliJ’s idea and set auto-compilation to true, and change a class in one module, it will automatically build the dependent modules and fire errors if necessary.

There are several issues some of which are poorly written code. For example this bug report ( http://bit.ly/YoLKxY ) during typing javascript the editor will block to update the document structure. Since the primary function of an editor is to edit, then that should not be blocked by any other secondary function enhancing the editing. Things like auto-complete would block editing and for every few character I type I will have to click Esc just to continue editing. Formatting of HTML, JSP and JavaScript during editing is totally screwed up. Even though the setting will specify a certain location for braces and indents, things will end up in totally different locations and they won’t be fixed until you mark the whole code and reformat it.

For their credit they have a very good core integration with maven. However, features are not finished nicely all the way to the end. I really don’t know if the project is losing volunteers and that’s why it is adequately tested or it is being steered to the death path to be replaced by an even slower and worse project aka JDeveloper.
