I presented about distributed systems at the University Politehnica of Bucharest. Here are the slides, with thanks to the inspiration sources all over the web (Mahout presentations, HBase and Hadoop presentations).

Automated deployment of distributed systems
There’s a new blog post up on hstack.org – Hadoop and HBase Automated Deployment using Puppet, written by yours truly. It also announces the open-sourcing of the code that we use to deploy a fully distributed system to one or more clusters in a semi-automated manner (we need to push the button 🙂 )
So, enjoy reading here.
HBase performance post
My colleague Andrei just posted a great article about HBase performance, complete with numbers and pictures over on http://hstack.org/. If you’re into the all NoSQL movement, you should definetly check it out (and I’m not just saying it because I know him 🙂 )
Get duplicate line shortcut working in Ubuntu
Problem: The default keyboard shortcut for duplicating lines (ALT + CTRL + Up/Down) does not work
Configuration: Ubuntu Jaunty, Eclipse 3.5
This is caused by the system using the same shortcuts to move to a virtual workspace above and below. Go to System > Preferences > Keyboard Shortcuts and assign a different key combo for the following two actions:
Switch to workspace up
Switch to workspace down
Duplicate lines works again.
Open files in gvim in new tabs
Aim: when hitting F4 in GnomeCommander, the file will open in a new tab of the existing gvim instance:
Options1: visual:
- Open Gnome Commander => Settings => Options => Programs
- In the Edit text field put this:
gvim -p --remote-tab-silent %s
- Save and restart Gnome Commander – not always needed, but helps
Option 2: editing the settings file:
- The file to edit is ~/.gnome2/gnome-commander
- Find the line :editor=blablabla and change it to :
editor=gvim -p --remote-tab-silent %s
- Save and restart gnome-commander
Vote, vote for Flex!
It’s that time of the year – the SourceForge 2008 Comunity Choice Awards. If you want to participate and like Flex (or AIR) you can click here to vote for it.
Go Flex!
Later edit: Seems I’m last in the platoon to read the news and encourage people to vote – Mihai wrote about this before as well as Remus and Cornel. You’ve beaten me to the punch, guys.
Google reader clip
S-ar putea sa fie disponibil mai demult, dar eu azi am observat – Google pune la dispozitia userilor de reader care sunt si bloggeri un “clip” in care pot afisa articolele partajate direct pe blog. Si cum eu m-am apucat recent de feed sharing, l-am si integrat (e chiar foarte simplu si rapid). Urmeaza sa intru si pe social networks si sunt doomed 2.0.
Cursa de recuperare …
Saptamana trecuta a fost una nebuna si trista. Si din cauze diverse am stat deoparte de calculator aproape 6 zile (which is huge), asa ca acum trebuie sa recuperez pe toate planurile. Si recuperez de duminica seara incoace, doar ca s-au strans multe:
- Work – deh, treaba care trebuia facuta, trebuie facuta.
- Feeds – tona de items care solicita un minim de atentie (si probabil vreo 20 de ore)
- Prezentari de facut
- M-am apucat inainte de variile evenimente sa citesc pe vreo 3 planuri. Drept urmare ma asteapta pe noptiera, birou si in laptop fix 3 carti diferite. Si nu vreau sa le las
- Blogurile care au cam inceput sa imi bata obrazul din cauza neatentiei. Inca un pic si isi dau stapanul disparut (am un draft pe blogul tehnic de fix 2 luni)
- Diversele experimente si idei abandoname pentru moment (Orcas, AIR, etc)
- Mai are rost sa trec si viata personala aici? 😀
Si eu stau sa scriu un post (tai punctul 5 de pe lista 😀 ) intr-o pauza scurta intre alte doua chestii. Damn it feels good!
