I spent a lot of time trying to figure out how to build matplotlib on Snow Leopard without using macports - I prefer to use homebrew instead and ended up with incompatible binaries, until I found ['This'](http://blog.hyperjeff.net/?p=160 "this post"). Notes

Edit make.osx

Not too obvious since doc [here]("http://ask.github.com/celery/tutorials/otherqueues.html") doesn't mention it.

Working configuration:

CARROT_BACKEND = "ghettoq.taproot.Redis"
    CELERY_RESULT_BACKEND = "redis"
    REDIS_HOST = "localhost"
    REDIS_PORT = 6379
    REDIS_DB = 0
    REDIS_CONNECT_RETRY = True #this one is deprecated
    BROKER_HOST = "localhost"  # Maps to redis host.
    BROKER_PORT = 6379         # Maps to redis port ...

Just notes to myself:

When I decided to move from movable type to wordpress, I wasn't quite happy with default wordpress cookbook. I also had an offer to have a cheap dedicated server instead of VPS, so I decided to test two things simultaneously:

* Preparation of new live server using fabric

* Deployment of ...

As a long time perl developer, I have admired Movable Type (mt). So recently I decided to upgrade to MT5. In the end I decided to move from movable type to wordpress, but this is my notes:

First I took chef's cookbook from wordpress and modified it so it ...

Some time ago I started playing with excellent tool vagrant. In this post I will show how to setup chef server using vagrant.

Preliminaries

I assume that you know what is vagrant [vagrant](http://www.vagrantup.com "Vagrant") and chef [opscode](http://www.opscode.com/chef/ "Chef")

My blog finally moved to wordpress. If you find any links missing please post a comment.

As a long time perl developer it is quite sad to admit that perl based Movable Type is worse than PHP based wordpress.

I am a bit fed up with MT, I looked at MT5 and as usual was seriously annoyed by MT backup behavior: I attempted to recover backup from mt 4 into clean mt 5 and hit usual wall with schema mismatch error. I believe recovery should work, no matter what ...

As a big fan of automatic software deployment and cloud computing, today I tried [chef]("http://www.opscode.com/chef/") following several tutorials [one]("http://agiletesting.blogspot.com/2010/07/chef-installation-and-minimal.html"), [two]("http://agiletesting.blogspot.com/2010/07/working-with-chef-cookbooks-and-roles.html") and [three]("http://www.themomorohoax.com/2010/07/31 ...

Definition: We say that a vector of decision variables $ \hat x^{*} \in F$ is Pareto optimal if there does not exist another $ \hat x \in F$ such that $ f(\hat x) \le f(\hat x^{*})$ for all $ i = 1, \hdots k $ and $ f_{j}(\hat x)< f_{j}(\hat x ...

In computer science it is common to measure algorithms performance by using O notation. Every book on algorithms development will start from this topic and although it is still good rule of thumb, the practical value of O-notation now becoming obsolete.

For example Mathworks dropped Flops since version 6, the ...

Does publication of my face in the magazine (large pdf), can be counted as academic? I am on page 23.

Two of the brightest fellows, Dr Evan Hughes  and Dr David Salmond (DSTL), who were my  examiners, recommended the award of the PhD.

I have a several friends, who have a great product ideas, based on complex scientific algorithms. Each time when I suggest using cloud computing for developing product we go through a round of questions. I will put them down here, so I can reference it.
