Scrum becomes a worldwide trend – jump to agile

Scrum is used worldwide. You make software projects in US, Europa, Asia, South-America ?
Forget the old-fashioned Word, Excel and MS Project driven software projects with lost deadlines and regular missing transparency.

Let’s join the agile methodologies!!!

Nice presentation from Brazil:

Update: Found the way to embed slideshare doc, click on wordpress button below the presentation on slideshare and copy the […] “link”.

Ubuntu Intrepid, Firefox and Flash

After upgrade from Ubuntu hardy to intrepid last year, i had nearly every day problems playing embedded flash on websites.
I hate it, but it was not my first priority to solve and a Firefox restart solved it every time.

Suddenly i found this simple solution: http://ubuntuforums.org/showthread.php?t=967049

apt-get remove flashplugin-nonfree
apt-get install ubuntu-restricted-extras

Works fine now. I can see all content from slideshare and youtube.

Mobile – it is for communication

Today I came across a very good post by Helen Keegan on “There is no future on mobile”

We forget that the mobile phone is a communication device

It was designed for us to talk to each other. It was designed for us to be able to communicate with our friends, family, colleagues and lovers by voice, text, instant message, email, facebook, twitter, whatever. But it’s about communication. In every region of the world, mobile data traffic is largely driven by social networking – whether that’s Peperonity, Cyworld, Facebook, MySpace, Twitter – it doesn’t really matter. It does mean that it’s the human communication that’s important to us and drives the desire to explore mobile devices further in order to find other ways to communicate with loved ones.

The mobile phone is personal, it’s precious, it’s an object of desire and it’s our access to the outside world. It’s also a necessity and a basic tool to participate in UK society (according to the latest Joseph Rowntree report).

intellij 8.0 memory settings

Just installed the new version 8.0 of Intellij Idea.

idea8_header

With default memory settings i got permanent OutOfMemory with nothing else as created a default webapp with one jsp (using Sun JDK 1.6.0_10).

Exception occurred during event dispatching:
java.lang.OutOfMemoryError: PermGen space

So, i modified the memory settings a little bit more aggressive than recommended on IntelliJ Blog:

edit idea-9013/bin/idea.vmoptions (no -server, no -Xms to let the VM decide min settings)
-Xmx512m
-XX:MaxPermSize=140m
-ea

It runs now quite well.

get usb headset working with Amarok or Xine

It is a little bit tricky to get a USB headset working with Ubuntu and Amorak.

(i never use KDE, but this tool is my current favorite music player under Ubuntu. Things changes, may be there
is a another favorite player anytime. For now, Amarok 1.4.10 rocks! I donated a small amount of money for the guys of Amarok -> good job !!!).

My current Amarok version from Ubuntu Hardy or Intrepid distributions (XFCE desktop) identifies on-board soundcard only.

But i want to listen to music from my USB headset!.
So a small little manual configuration, let Amorak play music out of my USB headset:
First you need to identify the sound card identifier, i took alsactl, but other ways are possible of course:
sudo alsactl names

This creates /etc/asound.names and there you can find your assigned device, for example:
alsactl24 {
name 'plughw:1,0'
comment 'Physical Device With Conversions - USB Audio (Duplex)'
}

Now open Amarok and configure
Settings / Amarok / Engine
– Sound System: xine Engine
– Output plugin: alsa
– Mono and Stereo: plughw:1,0
– 4 Channels and 6 Channels: leave empty (i left it untouched).

or look on this screenshot:

OK

Now you can here sound from your USB headsets!

disable system beep under Ubuntu completely

If you use XFCE and have not System/Preferences, but want to disable system beep completely:
echo "blacklist pcspkr" | sudo tee -a /etc/modprobe.d/blacklist

With next reboot cannot here the annoying system-beep or if you don’t want reboot, run:
sudo modprobe -r pcspkr.
