Hack the Gibson #73 & #74
Well, don’t hack it. Actually the last two episodes of Security Now! were very insightful and as far as I know without major mistakes. The interview with Peter Gutmann is very interesting and if you have time you should read the original paper: A Cost Analysis of Windows Vista Content Protection. My opinion about it?…

Hacker challenge over
The Christmas (Hacking) Story challenge is over and unfortunately I didn’t win :), so I publish my response: What is interesting about the files that Ralphie could see on the lamp server? nc is most probably netcat (http://netcat.sourceforge.net/), the “network swiss army knife” (the fact that it’s executable, as can be seen from the directory…

Implementing Web Services with Open Source Software
Today many services are available (both internal and external to a company) as Web Services, more specifically as SOAP. Companies like Microsoft, IBM or Sun have heavily invested in this field and made many of their products compatible with it (as a client and/or as a server). In this article I will study the different…

Two quick Linux / Ubuntu tips
If you find that you are running out of disk space and some of your applications crashed recently, you might want to look in your home folder.

Mixed links and commentary
A short post today, again: Via Ajaxian: Leafletter. A very interesting design concept, but remember that Flash files included in your site can access every portion of it just like third party javascript can! (Also their scroll bar seem very counter intuitive) Two problems with websites: the Authenium blog has comments disabled, so that I…

Script kiddies and the sensationalists media
There is a great urge in the media today to come up with more and more sensationalists titles. This is understandable, because their main job is creating content and their success is measured directly in number of visitors. This is why (at least from this point of view) blogs are mostly better because (a) people…

Mixed links and commentary
Since I’m very occupied at the moment, I won’t do a full post here, just some interesting links. I hope to get back to my normal schedule sometimes next week: Rift Widens Over Bug Disclosure – the discussion over bug disclosure continues. Why blurring sensitive information is a bad idea – an added note: if…

Linux tips – take two
A short Linux/Ubuntu tip: If you want to control what services (daemons in Linux speak) run when you start your computer, use sudo sysv-rc-conf from the command line. If you don’t have it installed, do a quick sudo apt-get install sysv-rc-conf. It’s a very small download (around 25 Kb) and it’s much more convenient than…

Linux also has a hosts file!
Update: I’m recommending that you use 0.0.0.0 instead of 127.0.0.1. Please check the link to see the reasons and how to modify your hosts file. Also, if you do the changes, the ping command at the end of this article won’t work (it will say something to the effect of “Destination specified is invalid.”, but…

If you want statistics, you better include the tracking code
Around mid-December I did a redesign of my blog (actually I chose a different template and tweaked it a little bit :D) and forgot to include the Google Analytics tracking code in the new template. The result was that according to statistics I had 0 visitors in late December – early January. First I thought…
