Per-file compilation time in a Scala/Maven project

Where is Moore when he is needed ? Scala is a fabulous language, the tooling is now quite good, but it still have one big drawback… One that makes wonder if XKCD 303 wasn’t drawn with Scala in mind. Scalac takes forever to compile anything. In a non trivial project, that forever means (tens of) […] Read more

Set up Eclipse workspace in RAM

In the last article, we covered basic optimization paths for Eclipse. But it remains that Eclipse spend an awful amount of time performing I/O, reading and writing big amounts of (often small) files – and you can’t imagine how numerous theses files are. Of course, there is all the class resources file you are editing […] Read more

Java LDAP reborn As you may know, I’m rather fond of the LDAP protocol and its open source server and client implementations.
