Chinese lottery in da house!

A few day ago Revuln a maltese security company has published a 0-day exploit in Samsung SmartTV's firmwares. The remote root exploit have a complete control on a TV: download USB media history, install any app, share drives etc. Some ideas come to my mind:It's not surprising! This is only a PC, why shouldn't be there any bug? These companies are optimalize costs (as each) therefore they use Linux or BSD as a base. That is the reason why there are alternative firmwares (SamyGO, OpenLGTV) and I think they will be as wide spread as alternative router ... [Read More]
About tiling WMs and other deviations
Wednesday, March 21, 2012 @ 05:03 PM Author: Peter Parkanyi

The personal computer itself is in a trouble these days, that must not be a question to anyone. With the rise of smartphones and tablets, fewer and fewer people use a PC as their primary computer. You can write notes on an iPad just fine, and you can read your mail and have your photos and manage your calendar, and you can facebook. Yes, this a verb.Power users, such as developers and designers are a different breed, though. I've recently read a rant about the ... [Read More]

Recently as I was getting closer to my birthday I decided to make myself happy and I buy a tablet. At least this was my first intention.I was especially looking for an Android tablet but I read about iPads of course.As usually when I am up to buy something I started to read reviews of tablets from all over the Internet. After I read a couple of reviews I started to feel that they have way too many features an many upgrades are about to be released on this quite new market. Frankly I don't see where this market goes, ... [Read More]
Airport security and logging
Tuesday, October 25, 2011 @ 12:10 AM Author: Kiss Zoltán

On December 25, 2009 Umar Farouk Abdulmutallab boarded a flight from Amsterdam to Detroit, Michigan and became known as the "underwear" bomber after he came very close to killing 289 people. Despite the $42 billion that has been spent on airport security since 911, he was still able to get through. Why is it that people feel nervous around technology being used in high-stakes situations, such as in airport security? Lets take a look at a pretty important difference between people and computer systems. An employee at a given airport is unlikely to one day without any warning signs just ... [Read More]

Digital astrophotography: beginning
Wednesday, September 14, 2011 @ 12:09 PM Author: Zoltán Pallagi

Update: this post is obsolated, the newest version can be found hereAlthough my hobby is the amateur astronomy and I've been watching the sky for a few years, I began to take photos about the sky only a few months ago. After I've got some experiences in this topic, I decided to write a blog, because it was not easy to get the necessary information how to do it or what type of pictures I can take with different cameras and devices. To tell the truth, I didn't want to spend a lot of money while I ... [Read More]
How to install Gentoo Linux next to an Ubuntu on an encrypted disk
Monday, August 8, 2011 @ 03:08 PM Author: Németh Balázs

"Let my original aims covered by mist, as I only wanna show you how to twist."Well I am not a poet so please forgive me for the bad intro. :)In this post I am going to talk about how to put Gentoo Linux next to an Ubuntu Natty system which was installed to an encrypted disk. Note that except the boot partition the whole disk has been already encrypted by cryptsetup (LUKS). Our present system also heavily uses LVM.Why Gentoo Linux and why Ubuntu? I do not want to make a distro war here, but you may want to read my ... [Read More]
A last minute blogpost about a Lenovo T410 specific kernel
Thursday, June 30, 2011 @ 06:06 PM Author: Németh Balázs

I don't tell any secret by saying that I am using Ubuntu Natty on my office system which is a Lenovo T410 series system. Why? Recently I found out that I am unable to make WIFI connections with the standard 2.6.38 kernel while my other colleagues can. I did not care why and after some ranting about the missing 2.6.39 packages from the kernel ppa I went to kernel.org to download the source of the latest stable version and compile it by myself.So after an hour or so I had my hand made compiled version running just fine. WIFI works as it ... [Read More]
