Why Ubuntu 10.10 is better than Windows XP?
I want to preface this with the following: I don’t want to pull a fanboy move here. The only thing I assert is that a recent OS (ie. Ubuntu 10.10) can give a considerable performance improvement (without changing the hardware) compared to an almost 10 year old OS (Windows XP). Without further ado, compiling a…

Java has some surprising amount of dinamism in it
Not long ago I saw some java code from Simone Tripodi. It generates synchronization wrappers around arbitrary objects at runtime in a typesafe manner with a couple of easy to understand lines of code. The heavy lifting is done by the dynamic proxy mechanism available from Java 1.5 if I recall correctly. The downside is…

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. Given one Ninjabox (the nickname for packet capture boxes from Endace) with a DAG card (some kind of custom packet…

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…

Copyright is not theft!
Recently there have been quite a few copyright-related posts which came up in my feedreader. 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…

Dear people: try to think harder, even if it makes your head hurt!
This again is the case of a couple of links on the same topic piling up in my reader (this tends to happen if you take a pause in blogging :-)): Gmail’s Spam Filter No Longer Effective? 60% of Facebook users consider quitting over privacy Poll: 93% say Facebook should make you ‘opt-in’ to sharing…

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…
