XStream is a nice Java library for serializing and deserializing objects. One of it's advantages is that it does not require the deserialized class to have a default constructor. But sometimes this will be a problem. A simple real-life example:
Wie schon erwähnt fehlt meinem neuen Notebook leider ein UMTS-Model. Nun ja, mein Handy habe ich immer dabei und dank der Fonic Tagesflatrate (2,50 EUR pro Kalendertag) kann ich in wichtigen Fällen darüber online gehen. Doch dazu müsste ich ja auch ständig das USB-Kabel mit mir rumschleppen. Glücklicherweise haben die Erfinder von Bluetooth schon vor vielen Jahren daran gedacht, dass man Handies ja auch als drahtlose Modem verwenden könnte.
Vor einem Jahr erschien im Linux Magazin ein Artikel, der die Anti-Spammechanismen von OpenBSD beschrieb. Obwohl ich mich damals entschloss, dies auszuprobieren, dauerte es bis zum vorgangenen Wochenende, dass ich endlich mal Zeit und Muse fand mich damit zu beschäftigen.
In my current Abobe Flex project, I needed to upload multple generated files and form fields to a server. UploadPostHelper by Jonathan Marston is a great for uploading one file at time, but sadly I couldn't use (or even modify) it - it's licensed under NonCommercial CC, and my project is a commercial one.
So I had to write my own code which I would like to share with other's (dual-licensed under MPL 1.1 and LGPL 2.1).
In my current Symfony project I have a model called "Country" and a model called "Region". A Region always belongs to a Country, and this country will never change.
I've used Doctrine's admin generator to create the administration backend:
In my installation, KDE failes to lock the screen on suspend / hibernate, even if the checkbox "lock screen" in the "Energieverwaltung" (how is this labeled in english? Power configuration? Don't know...) is enabled. So I've adapted this patch to Mandriva.
Create the file /etc/pm/sleep.d/50-lock with the following content:
Neben den klassischen WLANs "Uni Osnabrueck" und "FH Osnabrueck" sind beide Hochschulen seit längerem auch Teil des WLAN-Netzwerkes eduroeam. Für die Studenten hat dieses Netzwerk den Vorteil, dass sie auch den Zugang der jeweils anderen Hochschule mitnutzen können. Mit Kubuntu und seiner komischen NetworkManager-Lösung konnte ich mich dort nie erfolgreich anmelden, aber mit Mandriva geht es relativ problemlos.
Symfony provides a nice feature called "embedded Forms" (sfForm::embedForm) to embed subforms into a parent form. This can be used to edit multiple records at the same time. So let's say you have a basic user table called 'sf_guard_user' and a profile table called 'user_profile', then you might follow this guide to merge these forms together:
If you experience problems or poor performance using Ubuntu's latest nVidia driver nvidia-glx-177 (as I did with a "nVidia Quadro NVS 160M"), try to upgrade to version 180. A package has been build for the next version of ubuntu (called "Jaunty Jackalope"), but sadly it has not been backported to Intrepid yet.
Who cares, I'll explain how to use Jaunty's repository with Intrepid to install this driver. First, make sure that you installation is up to date:
Warning: At the moment I can not recommend to use this script in conjunction with filewriter if you use a journaling filesystem for your root partition (ext3, reiser, ...). The reason is that when using filewriter the initramfs-script in /etc/initramfs-tools/scripts/local-premount/resume_tuxonice mounts this partition read-only to get the hibernation file's target. Unfortunately, the journal will be replayed in any case, so "mount -r /dev/hdX" does not mean "mount /dev/hdX, but don't make any changes on it".
