ON subversion …

To work directly with subversion out of VisualStudio have a look at:

SCC providers for subversion:
so far there is no free SCC provider for subversion because the Microsoft SCC API is protected by a non-disclosure agreement
should be out soon.

Here is a comprehensive list of SCC providers for subversion.

There exists a real, but commercial one here:

Subversion Ressourcen

Subversion hat sich mittlerweile als Quasi-Standard durchgesetzt und löst nach und nach CVS in der SW-Entwicklung ab.

Hier ein paar Subversion links:

Requirements for an Agile Project Management Tool

Here are some requirements I think should be found in a PM tool supporting Agile Methodologies:


  • Web based
  • Multi-project
  • Use Cases (User Stories)
  • Feature based planning
  • Work Breakdown Strukture (WBS, PBS)
  • User Management
  • Support multiple methodologies
  • iterative planning as a basis (time-boxed)
  • is named differently, but at the ground the mean the same (sprint, iteration, …)
    • backlog
  • UP (OpenUP, ch/open, IBM Rational UP)
  • Crystal (all colors)
  • Feature Driven
  • Support two-level-planning (TLP)
    • coarse plan for the whole thing (milestones) (1st level)
    • breakdown in iterations (2nd level)
    • first only number of iterations are given (changeable)
    • second the next few iterations are planned roughly on a feature or use case basis
    • third, the nextmost iteration is planned in detail (features, owner, effort)
  • Report Generator
  • Export data to
    • MS-Excel (most important)
    • probably with templating engine (company specific templates)
  • PDF (for reviews)
  • Word
  • Should haves

    • Link to source control tool
    • Subversion
    • CVS
  • Workflow Management
  • Bugtracking or link to bugtracking tool (mantis, bugzilla, jira, …)
  • link to requirements management tool (IRqA, DOORS, …)
  • Powered by ScribeFire.

    How to avoid to become an agile developer?

    Browsing my favorite blogs I found a very good story how to build up your own kingdom in your company. Do not take it to serious ;-) and distribute to others.

    Compaq Proliant 1850R running Fedora Core 4

    A few weeks ago I made a bargain and bought a used Compaq Proliant 1850R.
    Here are the specs of the server:

    • Dual Intel PIII 600
    • 1 GB ECC Ram
    • Smartarray 3200 SCSI RAID controller
    • 4 hot-plug 37 GB SCSI HDD (running as RAID 5)
    • CD-Rom (slim-line IDE) … exchanged with a DVD-ROM
    • 2 hot-plug power supply units
    • embedded NIC (some Netelligent 10/100 UTP)
    • internal 35/70GB Quantum DLT tape drive

    The idea was to install Sun Solaris 10 (Release 2006/01) and Oracle 10g for testing purpose. Unfortunately, Solaris 10 did not install at all – also after doing some research on the net I did not get it to work. The Installer always stopped with “No disk found. Check cable etcetcetc …”. Yes, I tried to load the DU disks (mainly disk 2 with the driver for the Smartarray 3200 SCSI RAID Controller).

    After that I went with Sun Solaris 9 x86. After the net search I did for Solaris 10 the installation was easy. Feeding the DU disk for the Smartarray controller at the beginning of the installation the installer went through the whole process. Only I was a little bit worried why there no questions regarding the network (DHCP, etc.) popped up. After the reboot I saw why: the embedded network card was not recognized at all. After some more research on the net I came to the conclusion to try it with a Linux install despite the fact that I am a big fan of Sun Solaris. I think I will try to install Solaris x86 on a more common machine sometimes in the future.

    Now for the Linux trial.

    I decided to go with Fedora Core 4 (FC4) – in my opinion a state of the art Linux for Server installations. I chose FC4 because of my past experience with Red Hat Linux.

    There are some good pages on the net describing the installation of RHEL4 on these kind of machines. Most of the advices also hold for FC4.

    To make it short

    The installer did not work, so I had to do the following:

    • on the Grub menu press the letter for “change boot parameter”
    • enter linux text nousb nousbstorage

    The explanation:

    • text – use the text based installer, otherwise anaconda hangs
    • nousb and nousbstorage – disable USB support. Why? I do not know. The 1850R does not have any USB ports. There are sites on the web that claim that it has to do with a mouse that the installer tries to find. I can not verify or falsify that.

    The installer finds and initializes the Smartarray Controller, the NIC and finds the right graphics card and monitor.
    After the configuration of the system the installer starts formatting the harddisk (one logical volume – RAID 5). Here I thought it will hang again, because it stopped at 11%. So I went for a coffee (or two). On my return the installation was almost finished.

    The system hangs again after the reboot into the installed linux. I had to add the following parameter to the grub boot menu entry (press ESC on startup): nousb nousbstorage.

    And finally everything worked.

    I did some post installation work:

    • adding the nousb nousbstorage permanently to the grub boot menu in /boot/grub/menu.lst
    • install the HP ProLiant Support Pack (explanation will follow)

    Now the next step will be installing a database.

    I will add some links that I found on the net … find some already in my link list

    Cube upgrade with Powerlogix Dual 1.5 GHz

    A few month ago I bought a Apple Cube that I found on a swiss online marketplace ( I was addicted to this “computer” since the first time I saw one live in a shop in 2000, but as for many others, it was not within my budget at that time.

    It was a standard G4 Cube running at 450 MHz with 256 MB RAM and a 20 MB harddisk. This is not that much power in the year 5 after 2000, so I started to upgrade it bit by bit.

    First I startet with the obvious thing: more RAM … much more RAM!
    Since I had several Intel-based computers the last years I have a lot of old RAM modules laying around. But, unfortunately, not all are usable with the Cube because the height of the modules must not exceed 35 mm (1.38 inches high). Otherwise the casing will not fit.
    So I am stuck now at 1.25 GB of RAM.

    The next, second thing: bigger harddisk. I decided to buy a new silent one with 250 GB. Keep in mind, you need the Intech ATA Hi-Cap Support Driver to address the whole 250 GB. If you do not have this driver installed you will only see 128 GB of your big fat drive.

    After that there are two more options left: better video card and, of course, a processor upgrade.

    I decided to go for the processor upgrade (first ;-) ). So I did a little bit of research on the web looking mainly for reviews and experience reports. After some time I decided to go with the PowerLogix PowerForce47 Dual G4/1.5GHz. The worst thing were the two days I had to wait for the shipment of the processor :-) .

    As they say in their installation manual (which I had to print first – but this was the only downside) you have to be a little bit familiar with such an update. As I assemble my (Intel-based) PCs myself since 1988 I tried it without hesitation.

    Now I have a state-of-the-art Mac running OS X fast, and the best: I can now let the weblogic server run on one proc while I do some compilation on the other one. Very cool :-)

    Here are some links that may help other cubeowners:

    First of all check out They have a lot of experience reports and can also help if you have questions or problems. After I discovered this site it was my primary source for information (as a registered user you also get a small discount at

    Then, of course: The ad video for the cube at Apple’s site.

    The vendors of processor upgrade cards for the cube:
    Powerlogix (Cube upgrades)
    GigaDesigns (Cube upgrades)
    Sonnet (only one card designed for the cube)

    For those who want to install a harddisk bigger than 128 GB:

    RFID pilot experience

    In a pilot I participated as technology consultant we did a RFID installation in a warehouse and a shop. Whereas the technology run smoothly in the warehouse we had numerous problems with the installation in the shop. Starting from problems with the non-RFID infrastructure – mainly usability issues – and ending with antenna problems. The RFID antenna had to be re-calibrated to often (in my opinion).

    RFID technology depends heavily on the existing infrastructure, both, RFID and the
    place it is installed.
