  • Prezentarea despre Distributed Computing @Poli

    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). Distributed computing poli

  • 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,…

  • 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 🙂 )

  • Install Gitorious on CentOS 5

    Recently I had to install Gitorious on a CentOS machine. Instructions on how to do this are in a document inside the gitorious code base, but since I needed something repeatable and reliable, I’ve turned to my tool of choice – Puppet. So I’ve created a Puppet recipe which installs Gitorious behind a Phusion Passenger/Apache…

  • 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…

  • 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…

  • Fix iTunes + Windows 7 + iPhone

    Update: Using the latest iTunes 64bit with Windows 7 64bit, I had no more problems. Can’t vouch for 32 bit versions, though. Problem: After a first successful sync of my iPhone with iTunes on Windows 7, I rebooted my PC. Consequently, any attempt to start iTunes with my iPhone plugged in results in an error…

  • Enable additional ENV variables on linux for non-interactive ssh logins

    Use-case: run Hadoop with localhost as your only master/slave and with a custom JVM: echo JAVA_HOME=/home/user/jdk > ~/.bashrc echo JAVA_HOME=/home/user/jdk > ~/.ssh/environment sudo -i echo PermitUserEnvironment yes >> /etc/ssh/sshd_config service ssh restart exit ssh localhost ‘echo $JAVA_HOME’

  • Blogging tools

    This post is not a list of tools to use to make your blogging life easier. Recently I’ve switched my primary laptop from a Lenovo to a Mac. This in turn brought with it a need to change (almost) all of the software I used, including my blogging client. I use a desktop blogging client…

  • iPhone reloaded

    Just read the live coverage of the WWDC 2008 keynote by Steve Jobs on Ars Technica and seen details on the second version of the iPhone. Again the rumors were true – the second installement of the phone is more enterprise friendly, but most interesting – it’s got 3G, GPS and a price tag of…

  • 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…

  • Welcome Mihai

    Starting today, one of my colleagues, Mihai Corlan has started his own blog. If you’ve visited our local adobe site (myadobe.ro – sorry, romanian only) you have probably enjoyed some of his posts. He has posted on the myadobe blog for quite some time and now he’s got his own place to rant about stuff.…

  • OpenSuse 11 and WiFi

    A week or so ago I shuffled computers around the house. As a result one of my desktops couldn’t be reached by wired Ethernet any more, so I thought of going wireless. Bought a cheap Asus PCI-Wireless card (WL-138G) which worked like a charm on Vista and XP. That’s the sunny side of the story.…

  • 360 Flex Milan is over

    The first edition of the 360 Flex conference in Europe is over. It’s been three interesting days of talking to people, attending sessions and networking. Overall the conference was interesting, although there were less people that I was expecting – but I guess this is because in Europe the conference doesn’t yet have that much…

  • Gestures and interfaces

    Just stumbled on this first chapter of an upcoming book on Gestural Interfaces. It’s pretty interesting to read, and it good me wanting more. I am so putting this book on my Amazon wishlist. Go read the first chapter here.
