4 years ago we, the ScienceCloud group at DeIC, launched the scientific data-management service data.deic.dk.
It was a first attempt at building something like this out of open-source components: FreeBSD, ZFS, Apache, ownCloud/Nextcloud and involved engaging with similar projects in other countries (Switzerland, Australia, Germany, Holland) and open-source environments (Nextcloud, CS3).
Today this service hosts about 100 TB of … Read the rest
Our former intern and bachelor student Piotr just got his first paper published – in Future Generation Computer Systems.
keep scrobbling. But it’s not exactly getting easier…
This is a sequel to three previous posts on the subject of listening to Last.fm on my squeezeboxes.
Well, the recommendation feature of the Spotibot service stopped working after a while, so for at least a year now, I’ve been listening to my own library (loved Last.fm tracks and my local … Read the rest
This is the intended replacement for our old workhorse, data.deic.dk. Those who would like to try out new features targeted at researchers, please give it a try. You’ll need to be able to log in via wayf/edugain, i.e. you need to be affiliated with a European research institution.
The new features we’re exploring are:
- ORCID integration
- Zenodo… Read the rest
The classic “Process (aka Designing the Stop Sign)” nails the problem of (Over-) Design By Committee.
But is the real problem here using a committee? Can design not be meaningfully accomplished by group of people working together?
I claim the answer is yes and that typical problem is not the committee per se, but the clueless committee – regardless … Read the rest
I’ve finally been trying out Android lately, more specifically, trying out my OnePlus One. So, I’ve been looking for ways to keep my iPhone and OnePlus in sync regarding calls and SMSs. At least I’d like to have SMS to email forwarding on both devices. On Android there is Relay ME. On the iPhone, there are some pretty extensive … Read the rest
My mail setup is perhaps a bit unusual:
- I like to read and send all my email via gmail
- I also want to keep all received and sent mail on my personal mail server
The final destination of all my email addresses is my personal mail server and a copy of every received mails is sent to gmail.… Read the rest
This is a sequel to two previous posts on the subject of listening to Last.fm on my squeezeboxes.
Since my last post on on the subject, the number of ‘squeezeboxes’ in my home has actually grown – with of a couple of OpenSqueeze boxes. These boxes are simply boxed Cubieboard2 boards with Cubian Linux (a minimal Debian derivative) and … Read the rest
So, Ubuntu-14.04, Trusty Tahr, is out; and booting the cloud images requires a bit more hacking than booting the 12.04 cloud images. Here goes:
Get the image, resize and loop-back mount it:
Like Ubuntu, Fedora distributes cloud images and like in the case of Ubuntu (see my previous post), I’d like to boot the image without actually running a cloud. At least not an OpenStack, CloudStack or Eucalyptus cloud that is.
Again, I did not manage to find any simple recipe for doing this, but it turned out to be even … Read the rest
The more precise question is:
Do researchers at Danish universities need a supercomputer on the top-500 list?
A bit of background is useful:
The funding model for HPC in Danish academia, employed since ~2000, described in a previous post, has resulted in a decentralized HPC infrastructure which AFAIK is quite unique in Europe (other European countries have a

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.
Before taking off for Canada I just had time to attend the first day of the DeIC conference (scroll down for English) here in Denmark. Here‘s a summary of the plenary talks (sorry – Danish only).
The conference marked the initiation of the … Read the rest
Fountain, downtown Oslo.
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
It started as an elephant…
Thor dual-container POD.
My second visit to Iceland – for the Nordunet Conference.
Very fittingly, mostly a networking event – and an excellent one.
This time I didn’t even have time for the Blue Lagoon – but I had time to visit the Thor Datacenter.
