This release features the following changes: Support for updating over https (patch by msboom) […]

my_indexr: Script to drop and recreate MySQL indexes

As can be read in this article, I was in need of a method to quickly drop all indexes (except primary keys) from a MySQL database. After googling around a bit and being astonished that apparently no-one had written such a thing yet, I wrote the script that can be seen in that article. Unfortunately, […]

Think Bayes: Bayesian Statistics in Python

There’s a free download available of “Think Bayes – Bayesian Statistics in Python” over at it-ebooks.info. A small excerpt from the book: The premise of this book, and the other books in the Think X series, is that if you know how to program, you can use that skill to learn other topics. Most books […]

Increasing performance of bulk updates of large tables in MySQL

I recently had to perform some bulk updates on semi-large tables (3 to 7 million rows) in MySQL. I ran into various problems that negatively affected the performance on these updates. In this blog post I will outline the problems I ran into and how I solved them. Eventually I managed to increase the performance […]

Quick-n-dirty HAR (HTTP Archive) viewer

HAR, HTTP Archive, is a JSON-encoded dump of a list of requests and their associated headers, bodies, etc. Here’s a partial example containing a single request: { “startedDateTime”: “2013-09-16T18:02:04.741Z”, “time”: 51, “request”: { “method”: “GET”, “url”: “http://electricmonk.nl/”, “httpVersion”: “HTTP/1.1”, “headers”: [], “queryString”: [], “cookies”: [], “headersSize”: 38, “bodySize”: 0 }, “response”: { “status”: 301, “statusText”: […]

bbcloner: create mirrors of your public and private Bitbucket Git repositories

Initial mirror setup requires that you manually enter your username/password. Subsequent synchronization of mirrors is done using Deployment Keys. You can download a tar.gz, a Debian/Ubuntu package or clone […]

python-libtorrent program doesn’t exit

(TL;DR: To the solution) I was mucking about with the Python bindings for libtorrent, and made something like this: import libtorrent fname = ‘test.torrent’ ses = libtorrent.session() ses.listen_on(6881, 6891) info = libtorrent.torrent_info(fname) h = ses.add_torrent({‘ti’: info, ‘save_path’: session_dir}) prev_progress = -1 while (not h.is_seed()): status = h.status() progress = int(round(status.progress * 100)) if progress != […]

Python UnitTest: AssertRaises pitfall

I ran into a little pitfall with Python’s UnitTest module. I was trying to unit test some failure cases where the code I called should raise an exception. Here’s what I did: def test_file_error(self): self.assertRaises(IOError, file(‘/foo’, ‘r’)) I mistakenly thought this would work, in that assertRaises would notice the IOError exception and mark the test […]

Evolutionary Algorithm: Evolving “Hello, World!”

Note: The latest version of this article is always available from the Writings page in HTML, PDF, ePub and AsciiDoc (source) format. My interest in Evolutionary Algorithms started when I read On the Origin of Circuits over at DamnInteresting.com. I always wanted to try something like that out for myself, but never really found the […]
