Disclaimer: I know personally and worked with a good portion of the conference organizers and talkers. I label them with an asterisk*. The ShipItCon finally took place last Friday. I think it’s quite impressive, given the short amount of time since announcing it and being the first edition, that was so well organized. The venue was very good (and fairly unusual for a tech conference), and all the usual things that are easy to take as granted (food, space, projector, sound, etc) work like clockwork. Kudos to the organizers. The conference was… Read More
The new version of ffind v1.2.0 is available in GitHub and PyPi. This version includes the ability to configure defaults by environment variables and to force case insensitivity in searches. You can upgrade with pip install ffind –upgrade This will be the latest version to support Python 2.6. Happy searching!
I used what I learn and some decisions to create a template for new projects. Part of software development is mainly plumbing. Laying bricks together and connecting parts so the important bits of software can be accessing. That’s a pretty important part of the work, but it can be quite tedious and frustrating. This is somehow a very personal work. I am using my own opinionated ideas for it, but I’ll explain the thought process behind them. Part of the idea is to add to the discussion on how a containerised Django… Read More
I happen to take a look to this old post in this blog. The post is 7 years old, but still presents an interesting problem. “A mathematician purchased four items in a grocery store. He noticed that when he added the prices of the four items, the sum came to $7.11, and when he multiplied the prices of the four items, the product came to $7.11.” I wanted to check my old solutions again, with the things that I learn in the last years. At that time, I was still a newbie in… Read More
The new version of ffind (1.0.2) is available in GitHub and PyPi. This version includes the ability to execute python modules and scripts directly and some other minor improvements. Happy developing!
25 years ago, on 20th February 1991, Python 0.9.0 was released publicly… I absolutely love it and use it everyday, and it seems to be as successful as ever… For another great 25 years! Cheers!
What is cache More than a formal definition, I think that the best way of thinking about cache is an result from an operation (data) that gets saved (cached) for future use. The cache value should be identifiable with a key that is reasonably small. This normally is the call name and the parameters, in some sort of hashed way. A proper cache has the following three properties: The result is always replicable. The value can be scrapped without remorse. Obtaining the result from cache is faster than generate it. The same result will be used… Read More
Load testing is something very important in my job. I spend a decent amount of time checking how performant are some systems. There are some good tools out there (I’ve used Tsung extensively, and ab is brilliant for small checks), but I found that it’s difficult to create flows, where you produce several requests in succession and the input depends on the returned values of previous calls. Also, normally load test tools are focused in HTTP requests, which is fine most of the time, but sometimes is limiting. So, I got the idea… Read More
Because Fibonacci numbers are quite abused in programming, a similar concept. My first impulse is to describe them in recursive way: But this is not very efficient to calculate them, as for each is calculating all the previous ones, recursively. Here memoization works beautifully Taking into account that it uses more memory, and that calculating the Nth element without calculating the previous ones is also costly. I saw this on Programming Praxis, and I like a lot the solution proposed by Graham on the comments, using an iterator. The code is really clean.
