As some of you might have noticed, I moved to WordPress (after the Joomla installation I was running bit-rot due to a php upgrade of my hosting).
The content of the site is however still very old… If you care to see what I am up to more recently you are better of looking me up on:
Google Scholar : https://scholar.google.ca/citations?user=wb9DYOEAAAAJ&hl=en&oi=ao
In Hadoop: https://issues.apache.org/jira/browse/YARN-1051?jql=text%20~%20%22curino%22
… you get the gist …
As a end-of-a-post-doc activity I released the source code of several pieces of software:
When buying a used car you should check the clutch is ok… here is a mechanics-trick on how to do it.
to check the state of a clutch you can:
- pull-up the hand break completely
- put the gear-lever to a high-gear (e.g., 4)
- bring the engine high-up (as if you want to burn a light)
- release gently the clutch
Check the following:
- A good clutch will not slide and the result is that the car engine will shut-off (since the hand break is holding the car still, and the high gear is disadvantageous for the engine).
- A bad clutch will start sliding, the engine do not stop, the car doesn’t move, and you soon will smell dead-clutch.
In either case interrupt the experiment right-away (to avoid to further screw the poor clutch).
Enjoy your new car
This article present is a webdiary of the installation of a XEN-based virtualized server. The Dom0 of choice is OpenSolaris, since it provides the nifty features of ZFS.
We are buying a fairly powerful machine, a:
– 2xQuadcore XEON 2.2.6 Ghz 8MB cache
– 24 GB RAM
– 6 x 1TB Seagate 7200 RPM hot-swap SATA disks (32MB cache)
This will be soon installed with OpenSolaris and we will try to virtualize with XEN, to host DomU with ubuntu (old and new), and maybe a Windows VM.
