Plex is great piece of software. It’s a “complete media solution”. I installed it on my laptop (free) without editing a single file, I tested it on my iPad (it’s a paid app) and it was just working instantly. Then I also tested it on my Nexus 7 (paid app on play store as well) and it’s also working perfectly.

Then I discovered it can also do streaming through it’s web based interface, so it can stream to anything it doesn’t yet support. We could stop here but no: It can be installed on Debian stable hosts as well (which I love because they are easy to maintain [no daily updates and still pretty updated]).

As described here, the installation instruction for plex on Debian/stable is:

echo "deb squeeze main" | sudo tee -a /etc/apt/sources.list.d/plexmediaserver.list
wget -O - -q | sudo apt-key add -
sudo apt-get update && sudo apt-get install plexmediaserver

Some good reasons for learning python


President Obama thinks required programming language learning in high school is a great idea. So do I, and I think we should all start with python.

  • Writing code with it is very fast. When software engineers tell you “I can do it in 10 minutes”, in C/C++ they mean 4h, in java they mean 2h and in python they mean it.
  • You can really do anything, I’ve done some serial communication, bit level manipulation, network level event-based servers, multithreading, webservice providing and consuming, SQL and cassandra client faster than what I’ve been doing in any other language.
  • It’s easy to learn viagra pfizer 50 mg. You can start your first program right now and be good at it in 2 weeks.
  • It comes “batteries included”. You don’t have to install third-party libraries. Contrary to ruby, you don’t have to choose between the thousands of gems available, there’s almost always one official way to do things. Which leads to the next point:
  • It’s simple to read someone else’s code. This is because it’s high level language and you quickly know all the librairies.
  • It now has some IDEs. I know some people like to code in vi, but this is ugly and unproductive. Pydev is simple to install and supports a pretty good (or not so bad) auto-completion.

This leads me to two opposing ideas (but you’ll understand where I stand):

  • On a software architecture level, I think java (or C#) is the right choice for any complex or performance requiring system. IDE can really do there magic and most of the problems (mistakes, API change, etc.) are found at compilation.
  • But on a pragmatic/real-life level, I think python is especially relevant for companies (I’m really thinking about startups) who want to build and launch something quick, make it evolve easily and obviously don’t need performance. Your engineer brain might think “Yes, but it’s scripting, this sucks”. But who cares? In 3 years, your product will be probably obsolete, if not already dead and in noone’s hard-drive anyway.

If you feel python isn’t the right choice because you need to have a complex all-in-one-language architecture, you should have a look at message brokers. My favorite one is RabbitMQ. It works instantly (like any modern software should be), has client libraries in every language you can imagine and supports very interesting features like persistent queues, load balancing and replication. Load balancing means that if python happened to be a bottleneck in your system, you could just duplicate the instances and server two times more.
