In the afternoon I added Twitter Card and Facebook Sharing support to Tumblelog, the static site generator I wrote to create Plurrrr.
I also created a tiny Perl program to generate a text file with tweets which I can automatically tweet using another Perl program. I hope to get more visitors this way. For more information, see the aforementioned link.
On our way to the town centre my mother and I encountered a beautiful blue cat with white socks. The cat was very friendly and loved to be petted.
“Premature optimization is the root of all evil“: the famous Knuth-ism that we all know and… well, that we all know. It’s hard to go a day of reading programming blogs without someone referencing this and leaving their particular footnote on it. I suppose today I am that someone.

[W]e should pursue loose coupling, so one would be able to easily analyze/debug/maintain any class, without detailed knowledge about other classes within the system. The looser the coupling is, the more independent the classes are.
In the evening I read Six Shades of Coupling, an article by Mr. Picky.
The six types of coupling from those considered as the least to those that are the most welcome are:

In the afternoon, the twenty new black Lego scorpions, part number 30169, I had ordered the 30th of July arrived.
I had placed the order with Vintage Sets & Bits in the UK via the BrickLink website.

Everything in Python is an object. Some objects can hold other objects, such as lists, tuples, dicts, classes, etc. Because of dynamic Python's nature, such approach requires a lot of small memory allocations. To speed-up memory operations and reduce fragmentation Python uses a special manager on top of the general-purpose allocator, called PyMalloc.
In the evening I read Memory management in Python, a quick overview by Artem Golubin.
