I was recently asking myself why the P2V concept has not been more fully embraced by the open-source community – and generalized to V2C, virtual machine to cloud instance. From a scientific computing perspective, it would be ideal to seamlessly be able to prototype a data analysis in a virtual machine on a laptop and then run large-scale data … Read the rest
Cloud storage is often used for backup, but finding myself relying more and more on cloud-only documents, I felt a need for backup in the opposite direction: backing up my entire Google Drive to local storage – preserving the folder hierarchy. I was not able to find a script that does this, so I wrote one myself. I chose … Read the rest
For a long time I’ve been looking for a note-taking app that:
1) is available as an iPhone/iPad app ✔
2) synchronizes to either my own server or Google Docs/Drive ✔
3) has a web interface
4) supports organization of notes in hierarchical folders
5) has “todo” functionality (creation and due dates) ✔
6) allows assignment of priorities ✔
This … Read the rest
Since my last post about SqueezeScrobbler on my Squeezebox, I’ve enjoyed 3 years of LastFM listening on Squeezeboxes, Linux and Mac boxes, iPhones and iPads.
Well, this fall, LastFM announced that they would hit my listening pleasure with dual strikes: deprecation of the old API and discontinuation of the radio service in other countries than the US, UK and Germany. … Read the rest
Back in Canada for my second 3PGCIC conference – this time as coorganizer. A long flight followed by a small one and a taxi ride – I just managed to arrive in time to present my paper on REStful web services for distributed computing.
It was a short stay, but I took a walk around downtown Victoria, saw a few … Read the rest
This post is a reflection on the DeIC conference I attended in November 2012.
The conference marked the initiation of the … Read the rest
When I saw this, I knew we’d have to to arrange some babysitting for the 19/10:
Chris was in top shape.

The first trip in my new role as cloud technologist of DeIC went to Oslo – for the Nordunet 2012 conference – my second one of the kind. These conferences are primarily a meeting ground for the Nordic NRENs to meet with each other and a few of the other major NRENs like SURFnet, and AARNet … Read the rest
Our second son was born 27th of November 2011.
A small miracle he is
Back in Barcelona to present a paper at 3PGCIC-2011 – a well organized and pleasant conference with a varied program. Good discussions on distributed computing. Excellent social arrangements including the reception banquet at the charming Institut d’Estudis Catalans and a visit to the Mare Nostrum supercomputer of the BSC – located in a former chapel.
Recently I’ve stumbled upon the terms citizen science and citizen cyberscience. The last term was apparently invented by Shuttleworth Fellow Francois Grey as a label for BOINC-based distributed computing projects like seti@home, folding@home and his own lhc@home. Grey is also behind the Citizen Cyberscience Centre in Geneva – on the web pages of which there’s more information to be … Read the rest
As exemplified on the pictures above (from the photo gallery of one of the students), CERN School of Computing includes a good deal of extracurricular activities. Which probably goes a long way in explaining the good and humorous atmosphere in the classroom.
In this post I’ll try to explain the vision behind a software suite I wrote at the Niels Bohr Institute, University of Copenhagen, 2009-11.
The ideas for the software arose from my dual involvement with the high energy physics and the e-science groups. Some of the code originated in previous projects, including distributed computing efforts of the ATLAS experiment at … Read the rest
Came across this CD by chance. The soloist – living here on Østerbro, is the grandson of the composer .
Post-romantic, austerity, suspense and longing. Apparently it appeals to the younger generations
Pablo (and tia Chata) enjoying the music:

I’m quite happy with my small HTPC running Boxee on Ubuntu. The hardware is a Zotac Ion board with an Atom CPU and an Nvidia graphics card. Both software and hardware have their issues, but after enough hacking I’ve a setup that gets the job done wrt. watching movies off my file server. My main gripe has been the lack … Read the rest
In this exercise we’ll solve the same assignment as in exercise 1, but using a prepackaged GridPilot application.
- Download and install GridPilot
- Start GridPilot and answer the initial questions – enable only the computing system “GridFactory” and set the submission host to gridfactory.nbi.dk
- Import the app “ttbar_exercise”
- Select the application/dataset “ttbar_exercise-100k-events” and click “Run”
- Select the application/dataset “ttbar_exercise-merge” and
