This scientific visualization of a computer simulation depicts the inevitable collision between our Milky Way galaxy and the Andromeda galaxy (also known as Messier 31). NASA Hubble Space Telescope observations indicate that the two galaxies, pulled together by their mutual gravity, will crash together in a near-head-on collision about 4 billion years from now. The thin disk shapes of these spiral galaxies are strongly distorted and irrevocably transformed by the encounter. Around 6 billion years from now, the two galaxies will merge to form a single elliptical galaxy. ...

I would like to ask for help in compiling a list of as many TCS-related conferences and workshops as possible. My main motivation for doing this is to plan possible blog coverage of more theory venues – finding correspondents attending these events who would be willing to write either brief or in-depth blog entries about events they are attending. Beyond that, I hope a list like this would give everyone a better sense of the lay of the theory land. ...

Typical blog posts about Dropbox security concentrate on data or network encryption. I want to talk about protecting your system from Dropbox the application, as well as Dropbox the company. In this blog post I tell you how to prepare for a theoretical scenario where Dropbox turns malicious. I’ve done a number of things to make Dropbox run in a much more secure fashion on my Ubuntu laptop. Hopefully I will introduce you to some vulnerabilities that you weren’t aware of, and teach how to protect against them. Many of the attacks and defenses described here are portable to apps other than Dropbox. ...

I’ve written before about the somewhat doubtful advantages of Class-Based Views. Since then, I’ve done more work as maintenance programmer on a Django project, and I’ve been reminded that library and framework design must take into account the fact that not all developers are experts. Even if you only hire the best, no-one can be an expert straight away. Thinking through things more from the perspective of a maintenance programmer, my doubts about CBVs have increased, to the point where I recently tweeted that CBVs were a mistake. ...

Apparently, in Python, it is easier to ask for forgiveness rather than seek permission. That is to say, the normal approach when writing Python code is to assume that what you are trying to do will work properly. If something exceptional happens and the code doesn’t work the way you were hoping, then the Python interpreter will tell you of the error so that you can handle that exceptional circumstance. This general approach, of trying to do something, then cleaning up if something goes wrong is acronymically called EAFP (”easier to ask for forgiveness than permission”). ...

Any application of typography can be divided into two arenas: micro and macro. Understanding the difference between the two is especially useful when crafting a reading experience, because it allows the designer to know when to focus on legibility and when to focus on readability. This article focuses mostly on a few simple macrotypographic techniques”with a dash of micro”and on how to combine them all to build a more harmonious, adaptable and, most importantly, readable Web page. ...

”La pornografía infantil es genial,” dijo entusiastamente el sujeto. ”Los políticos no entienden el intercambio de archivos, pero entienden la pornografía infantil, y la quieren filtrar para ganar puntos con el público. Una vez que los convenzamos de filtrar la pornografía infantil, podremos hacer que extiendan el bloqueo al intercambio de archivos.” » falkvinge.net
