Java Date objects can mutate, even when read
Ran into this problem a couple of months ago, when we saw some strange dates in production. So I dug into the Java library sources (thank you Sun for providing those!) and found that Date objects aren’t always “normalized”. Rather, sometimes a “denormalized” value is stored which is later (lazily) normalized. The normalized value isn’t…

TigerChef review
Lately I’ve been experimenting with some simple cooking, and of course for cooking you need cooking equipment. TigerChef is one of the many sources of cooking equipment you can get, although they are oriented more at restaurants than individual needs. Anyway, I’m quite happy with the initial experiments and with the help of my dear…

Problems (and a semi-solution) for tcpdump with DAG cards
Documenting here for posterity, since I didn’t find much information about it on the ‘net: Disclaimer: I’m not a network head, just an amateur who dabbles with it when he needs to fix a problem.

shuttledirect review
The purpose of this website is to offer prebookable Airport taxi transfers. This means that you can rent a transportation method to/from the airport before you even embark on your journey. Is it worth it? I have to admit that I’m far from being a big traveler, but until now every airport I’ve been to…

This is of course a complicated and layered problem which can’t be solved in the couple of paragraphs of this blogpost, but at least I can post a bunch of great materials which should contribute to the edification of all…

Who is hype-free?
I’ve done a writeup about the name of blog when I started it. However recently two links came up in my Google Alerts: The first one is from Urban Dictionary and it defines hype free as “Slang word for drug free”. The second one is from Yahoo! Answers and states pretty much the same thing…

On the hopelessness of pulling content from the interwebs
In the last couple of weeks I had at least two cases where I saw a (provocative) post come up in my feedreader, click trough to read the entire piece (BTW, partial feeds just suck!), just to find that the owner removed the post. The first was from the DynDNS blog named “Open Dialogue” (apparently…
