It has been years since PAM was hit by a serious bug in PAM, but people who upgrade to libpam-systemd version 44-1 can find that sudo stops working. Reading the bugreport on Debian and FreeDesktop.org it doesn’t look promising as it also effects other distributions. For now it may be wise put systemd on hold in case the package transfers from unstable to testing.
In the past I already removed Flash and Mono from my systems due to security concerns, but since CVE-2011-3544 it was the final call for Java. It took some dependency checking as Debian was replacing OpenJDK with GCJ or vice versa in most cases, but the command below finished that on a lot of systems. I said farewell to NetBeans a long time ago since it was to slow on my system and the only thing left was LibreOffice Base that needed to be removed as well.
$ sudo apt-get remove --purge libgcj12 libgcj-common gcj-4.6-jre-headless \ libgcj12-awt default-jre-headless
This action also made me wonder about the state of LibreOffice as it is mainly a big blob of code on the system like Firefox is as well btw. I read on there website somewhere that making Java an option is a long term goal, but will it be enough? For now it should be, as I prefer my documents in OpenDocument-format. When the next GTK3 based version of Abiword and Gnumeric are released I need to do some testing again to see if they support OpenDocument now better.
In a previous post, it became clear that censorship in The Netherlands has started. Due to the nature of the Internet and how it has been implemented in most lands, it means there is no central point of control to stop all to an IP-address. This means every network owner needs to take action, but how do they do it?
In the case of thepiratebay.org, it looks like it has been done by manipulating DNS-answers. The first attempt is just using the DNS-resolver from the internet access provider and the second is an attempt using Google public resolvers.

By just changing DNS resolvers on the client or internet router the censorship can be bypassed for now. The question remaining is how long this is going to stand when the first article is published by a big computer magazine on how to bypass it. Or when sites also get a .onion to bypass DNS completely.
As from now all my DVD’s are for sale on Bol.com and yes in March I’ll join the month of not spending a penny on the entertainment industry which was proposed for SOPA and PIPA. It only make me wonder how ACTA is going to influence the Internet when it gets approved.
With Firefox 10 WebGL works and there for also Google Street View works without the need of Flash. Yes, another dependency on Flash has been removed. The previous major dependency was YouTube, but as some may have noticed they also are in a transition from Flash to HTML5 video where you get the HTML5 variant when Flash doesn’t work.
As more and more websites switch from a Flash-player for video toward HTML5 in under a year it makes you wonder what WebGL is going to change. Was HTML5 a year ago only for the geeks and cutting edge, now more and more starts to depend on it. With HTML5 Canvas a lot of Arcade games where rewritten to run in a webbrowser. With WebGL the question comes when Doom has been rewritten to run in a webbrowser. Maybe something for a Google Summer of Code project?
