How to trace and visualize POSIX threads

by ao2, April 5, 2013
in

Writing even a simple multi-threaded program is a complex problem, synchronization issues are always around the corner, causing race conditions which can lead to deadlock or resource starvation; and the stress of not being sure that our program works correctly is another component of the complexity.

Some relative of mine forgot the password to access their e-mail account, but they were still remembering the pattern they used to pick it up, and that pattern could be easily represented by a regular expression. They did not have a backup email address to be able to use the password-reset mechanism.

Hacking a USB blood pressure meter

A blood pressure meter with a USB port happened to land into my hands, only Windows was supported for downloading data to a PC, and I wanted to see how the device interacted with the software and try to “free” it so that it could be used elsewhere.

Accessing authenticated feeds with Liferea

by ao2, February 21, 2013
in

I use RSS/Atom feeds a lot, they are a relatively efficient way to follow stuff around the web, and they are also privacy-friendly tools to a certain degree: I can follow my friends and family on Youtube, Flickr, and even Twitter (at least as long as API 1.0 is up and running, bah...), without having to explicitly tell the companies behind those sites whom I am friend with. Privacy is not only about “what you do”, but also about “whom you know”.

Have you ever typed suod instead of sudo? I do that quite often; maybe I am becoming typing dixleysc, who knows.
