Time to Jump the Box

A while ago I talked about Bitnami, that enabled you to jumpstart several OpenSource stacks. Now I just noticed “JumpBox“…

JumpBox Open is a collection of easy to use virtual appliances for Open Source software. Each JumpBox is focused on a single task (or single application) and is carefully crafted to capture the best practices for how the software should be implemented. The goal is to save you time and allow you to get more done with less effort. JumpBoxes will run on all of the popular virtualization platforms including VMWare, Parallels, Microsoft Virtual PC/Server, Virtual Iron and Xen.

JumpBox might help you to deploy certain services faster, just like LAMP jumpstarts your basic webservice environment!

Institutions versus Collaboration

Check out the following TED presentation on “Institutions versus Collaboration“. It’s a very insightful presentation about the difference between institutions and collaboration. You might actually say that you can identify the closed versus open source movement in there. Institutions want to capture the most performance driven resources, and collaboration focuses on capturing the broadest spectrum of available resources.


In this prescient 2005 talk, Clay Shirky shows how closed groups and companies will give way to looser networks where small contributors have big roles and fluid cooperation replaces rigid planning.

Installing Asterisk on a Linksys WRTG

A while back I wrote a small piece about installing OpenWRT on a Linksys WRTG. This part will be focussed on installing Asterisk on your WRTG.


Base Install
First we’ll be installing “OpenWRT” as our base “OS”. We’ll take the latest WhiteRussian for this. The flashing is done, when the progress indicator seems to hang.


root@OpenWrt:/# cd /tmp/
root@OpenWrt:~# wget http://downloads.openwrt.org/whiterussian/0.9/default/openwrt-brcm-2.4-squashfs.trx

Unlocking linux …
Writing from /tmp/openwrt-brcm-2.4-squashfs.trx to linux … [w]

Now we’ll connect to our newly installed device, in orde to:

  • Setup a password
  • Update/Upgrade the packages
  • Install Asterisk

Your favorite Webapps as easy to installable stacks


Today I stumbled upon an article mentioning the existence of BitNami. It was an unknown product to me, but I think it has some potential. Imagine the power of Lampp combined with your favorite cms/wiki/…

MySQL to be acquired by Sun

The speculations

  • Integration with Java : At the moment Oracle is seen as the “prefered database partner” for J2EE applications. This might be the start of a business move to get MySQL into this position.
  • Marketing / Image : MySQL is a popular database, and has it’s respect within the OSS community, so it’s a good for the PR. (Yet expensive if that would be the only side…)
  • Wide support : Whilst SUN was already working with PostgreSQL, this might allow them to give their customers the choice between three database systems (Oracle, PostgreSQL & Mysql) with their products.
  • Competititors : Will RedHat & IBM focus on getting PostgreSQL in the lift? In order to put (financial) weight into the alternative…
  • Engine collisions : Given that it would be a vendor showdown, how will it turn out of MySQL as their best enginers (InnoDB & BerkeleyDB) are owned by Oracle?

Nine Characteristics of Free Software Users

The “9 Characteristics of Free Software Users” (by Bruce Byfield) is an interesting read about his view on the nine characteristics of Free Software Users:

Free software users :

  • expect open licenses and no activation methods
  • expect regular upgrades and patches
  • expect to work the way they choose
  • want control of their own systems
  • explore
  • expect to help themselves
  • don’t fear the command line
  • learn software categories, not programs
  • expect access to developers and other employees

His ConclusionFree Software
How long these characteristics of free software will continue to exist is uncertain. In the last few years, a new category of free operating system users has begun to emerge: those who remain entirely on the desktop. In the rush to become more user-friendly — which usually means more like Windows — the chance exists that the free software user culture will become unrecognizable to long-time users in the next few years.

However, that seems unlikely. For the most part, the purely desktop user’s sensibilities are not sapping the free software culture so much as being accommodated and isolated as a special case. Unless they are content to stay in their normal routines, within a year or two, desktop users will face some problem that they cannot solve without becoming either more adventurous or more in contact with the mainstream culture. When that happens, they will have taken the first steps away from being passive consumers and towards becoming the owners of their own machines.

OWA Most Popular – version 1.2

OWA Most Popular has been updated.


Seperate function
It is possible to call the function directly in your php code (hint: templates), by using the following function:


New algorithm
The widget will use weighted algorithm, if you would set the variable $style_owa_popular to “weighted”. The formula is pretty simple, being:

(Sort) Factor = number of visits / (date difference (in days) + 1)

Important note : This weighted algorithm is pretty (system) resource intensive, I would advise you to use some form of caching mechanism in combination with this option.
