The annoying double “is” October 11, 2010 No Comments

Since I arrived in the United States, I heard a lot of people using a phrase that I always found very awkward. People tend to say things like: The problem is is that the economy is not in good shape. I’m not really trying to talk about the economy here, it was just an example. […]

Compute MD5 or SHA hash of large file efficiently on iOS and Mac OS X September 7, 2010 29 Comments

Computing cryptographic hashes of files on iOS and Mac OS X using the CommonCrypto APIs is fairly easy, but doing it in a way that minimizes memory consumption even with large files can be a little more difficult… The other day, I was reading what some people were saying about this on a forum about […]

Configure common command-line tools on Mac OS X January 29, 2009 1 Comment

Even if you properly configured the Terminal application on your Mac, you may think that using it is difficult, and not intuitive at all. Indeed, with the default configuration for the common command-line tools, you won’t get syntax highlighting within vim, nor will you have a shell which facilitates your work, and so on. But […]

Configure Terminal on Mac OS X January 28, 2009 No Comments

Every time someone asks me for help about something geek on a Mac, I often prefer to use the Terminal, because I never got used to editing a configuration file under /etc with a graphical text editor. Don’t misunderstand me, I am not a Terminal addict, and I often prefer using graphical tools that are […]

Draggable Screen Ruler for Web Development January 25, 2009 1 Comment

When doing some web development work, I used to use Screenshot Plus to measure the width of some elements. While this Mac OS X widget is very handy, it wasn’t very appropriate for this job: it required me to load Mac OS X’s Dashboard, activate Drag a picture in the widget, drag around what I […]

Installing Tomcat on Mac OS X May 13, 2008 10 Comments

Having to use Tomcat for an important project I am working on, I installed it on my Mac. However, in the beginning, I didn’t make much effort: I just uncompressed the official archive in my /usr/local, and I was able to start and stop Tomcat manually, that’s all… But today I decided to learn a […]

mmv on Mac OS X May 12, 2008 8 Comments

Since I switched from Debian and Ubuntu to Mac OS X, I got used to most of the differences between those operating systems. Yet one very important thing for me was still lacking: A command-line utility called mmv…

Japanese in LaTeX documents in Unicode with MacTeX May 10, 2008 13 Comments

Since I discovered LaTeX, I have become a real fan of this typesetting system. Yet, something bothered me very much: I could not use easily Japanese with LaTeX using a normal encoding, that is to say using UTF-8. Using CJK is not too difficult, but getting CJKutf8 to work is much harder. I just couldn’t […]

A matter of language March 3, 2008 1 Comment

As you can see, although English is not my native language, I chose to write articles in English for my personal website. The reason why I chose to write in English is quite simple: English is the most spoken language in the world, and I didn’t want to translate every article in some secondary language. Yet, I […]
