"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects." (Robert A. Heinlein)

Ubuntu 10.04 NBR on EEEPC 701(4G)

I've been recently asked by a friend to upgrade his EEEPC 701 (4G) to a more up to date operating system (it still had original Xandros running). I decided to install Ubuntu 10.04 (netbook edition) since I use it, and I'm quite satisfied of it, while the latest Ubuntu version performed poorly on my EEEPC 900 so I supposed it could only be worse in the EEEPC 701.


Installation and first impressions

As usual I backed up the EEEPC home folders (I almost forgot how limiting original Xandros “easy mode” was), I prepared a bootable SD card, booted the EEEPC from it and proceeded with the usual install steps. When prompted for disk partitioning I, of course, chose to use the whole disk.
After install I briefly tested the new system and everything seems to work fine, the boot time was about one minute and half and all the hardware has been properly recognised. All but the battery which shows the same annoying message I have on the EEEPC900. Ubuntu Netbook edition appears being still fully usable also with the smaller EEEPC 700 screen resolution. Only negative point the newly installed operating system takes up to 80% of the small EEEPC internal SSD drive.


Not the latest computer with not the latest operating system so … but it has been, in my opinion, an experience worth to be shared. One of the good points in Ubuntu is being able to “reviving” old machines and making limited hardware a little less limited. I hope they don't forget this while looking for new solutions like the new Unity desktop.

Nokia QT: Compiling a Symbian application

After my initial testing of Nokia QT I had still the whole mobile application compilation part to test. So, once the Ubuntu upgrade season has ended, I decided to take some time and try to compile my simple “hello world” program as a Symbian application and test it on my Nokia 5800 phone.
Linux version of Nokia QT, as I did already write, doesn't directly support compilation of mobile applications. This is some way solved by the “remote compiler”; an experimental service, provided by Nokia forum, that compiles sources sent to it returning back the mobile device installation file. The whole process might look complex at first, but it's well documented both in Nokia QT help files and in forum's pages.

Remote compiler configuration

In order to access to the remote compiler service you must be registered to Nokia QT forum; once registered you can configure your user-name an password in remote compiler configuration form and start using then service.
