Dynamic or static typing?
Working is Java (Eclipse more precisely), I came to value very much the features which it offers related to exploring / manipulating the source code. I’m talking about things like “take me to definition”, “show me where it is used”, refactoring features, etc. This made me thinking: isn’t really the difference between static and dynamic…

Vendor included backdoors
An other reason to make sure that you use your available software to the maximum extent before going out and deciding to remediate your software problem with more software 🙂 Vendor included backdoor can appear for multiple reasons, but there are two big categories: “Easter-egg” like feature (some programmer decided to put in a piece…

Calculating the intersection of two Java sets
This is my simple stupid Java tip for the day: to nondestructively calculate the intersection of two Set’s (ie, retain both object), do the following: Set intersection = new HashSet(s1); intersection.retainAll(s2); Taken from Java Tutorials. Lessons learned: before implementing code which even vaguely seems that it should already exists, check with your favorite search engine.…

Daily funny
Via Mechanix: the difference between JPEG and PNG illustrated. A similar topic would be: don’t use the same image for the thumbnail and the big image! Just because you said width=”320px”, it will still needs to download the whole image!

Fiddling with the comment system
My friend Dan D. mentioned that the new inline commenting system wasn’t playing nice with NoScript. After a little looking into it I found that indeed, Blogger is using JS to render the form (why?). To reduce the pain a little I’ve added a link to the old method of leaving comments which should appear…

Mixed links
Via /dev/random: the story of a fictitious penetration testing. Very interesting, eager to read the rest. From Kim Cameron’s Identity blog: Leaving a comment (with CardSpace / IdentityCards). The first time you do this it takes a whopping 11 steps! I fail to see how this is better than current systems or OpenID. (I’m talking…

Enumerations in Java
Starting to (professionally) program in Java, one of the things which bugged me were the constant declarations in classes which implemented struct-like idioms: class Foo { public static final int FOO_1 = 1; public static final int FOO_2 = 2; public static final String FOO_3 = “42”; … The code referencing this seems even more…

Anti Malware Testing Guidelines
Via the ESET blog: the guidelines for testing Anti-Malware products were published by AMTSO (the Anti Malware Testing Standards Organization). Go and read them if you are so inclined (each of them consists of only 5 pages – you have to give them props for brevity – although maybe they just wanted to avoid being…
