2012-01-22T08:54:00.000-08:00

I quote a thread from reddit and if you still use zope/plone you fail , there is nothing pythonic in the zope I did a beginner mistake once to think that zope is somehow python and i could handle all the complexity and zope core ugliness but now I know the complexity monsters can't be tamed (include there XML , JAVA2EE, zope ... ) As a Python programmer, hardly anything you knew was useful

Ie9 on kvm-linux

2011-11-21T08:54:00.001-08:00

The steps/scripts for using ie9 test machine are quite easy to follow if you are using virtualbox but what about kvm-linux ? I followed the guide to make vhd to kvm raw This guides works but it creates a raw partition of 127G in size so is not so good : qemu-img convert -f vpc -O raw Windows\ 7.vhd Windows7ie9.img so i used this command line instead: qemu-img convert -f vpc -O qcow2

#Ubuntu After the uTorrent page was virused i recommend QBittorrent to anyone

2011-11-11T11:35:00.001-08:00

I'm pissed utorrent doesn't make a client for Linux until the endof the year (only next) but in a sense we Linux users don't really care , there are many torrent clients to choose from One that i love is qbittorrent. It works great on all platforms , it is written in QT framework and it looks and feels just like uTorrent minus the crappy bars and viruses Did i mentioned that is small and

2011-10-03T05:48:00.000-07:00

There is a known bug with Image Magick : it can be very slow when used with openmp enabled (by default in debian/ubuntu) on multicore systems (almost on all servers these days) It is eating a lot of cpu (50-100% for each core) instead of idling at 1-2% (for simple image manipulations) It was strange for me that one single core server was faster than a quad core in the same specs with the rest of

Half the point of the "cloud computing" trend is to lock people in to one provider's weakly interacting web service, and, by extension, into the controlled ecosystem of third-party services that

Why should you avoid eucalyptus and mysql too - Open scamware

2011-05-19T22:59:00.000-07:00

But Eucalyptus has its own burden to carry. Eucalyptus might be open-source, but it uses something called an open-core model. Translated: There's a free community edition of Eucalyptus for everybody, but more advanced features beyond the basic stuff only go to paying customers. This is exactly the model Mickos employed at MySQL, and it upset people then too. http://www.theregister.co.uk/2011/05
