From time to time it happens. While working on a remote system via SSH the connection freezes. Mostly due to bad Wifi connectivity or some gremlins in between have just messed up. What you should NOT do is closing the terminal window. It is
lame bad practice. What you should do is: Continue reading

Recent news about the gem replacement vulnerability made want to check all installed gems on my systems. The news states that gems that have not been updated since 8 February 2015 could possible be maninpulated. Keep in mind that this is a theoretical attack vector. As far as I understand no attack making use of this approach has occured.
As there is no onboard way to check which currently used gems have not been updated since Feb 8th, 2015 you need a small script for checking. I found one called check_gems.rb from David Cuadrado. It checks all gems installed on the system. Continue reading
Everything in our western society is software based, is IT-based. What seemed impossible only 20 years ago is now part of our everyday life. Software has taken over taxi services, classifieds, news consumption, movie and tv consumption, book delivery, cars, energy destribution, warfare and many more.
A new term has emerged for software-based innovation that transformed our western life style signifcantly: disruptive innovation. It means that established businesses were hit hard or were completely destroyed by a new software driven solution. Common examples are Uber, Craigslist or Netflix. Continue reading
Software getting simpler is just an illusion. The opposite is true: Software has gotten even more complicated over the past 20 years. Software nowadays consists of layers over layers of other software. Some of those layers are located in other geographical locations; and in those locations even more layers of software exist. The main reason why most people think software has become simpler is because they only see the final layer on top of all other layers. It is the shiny layer created by skilled artists and polished by countless tests and interviews with target audiences. What people see when they start an app on their phone or tablet is just a tiny fraction of what this software actually consists of. Continue reading
Ever since Android 4.4 changed the security policies for storage no Android app can make use of SD card storage outside its app owned folder. There is a simple workaround that works like charm for the DS audio app: We move parts of the DS audio app onto the SD card. With this done an app owned folder was created on the SD card that can then be used (or misused) as download directory. Continue reading

Something I ran into quite often lately is problems with installing VMware Tools for Linux Mint. Meaning, your host runs a Windows operating system with VMWare Workstation having a Linux Mint inside the virtual machine. Continue reading

The default save location of the key pair (public and private key) will be shown. It should always be ~/.ssh (/home/yourusername/.ssh).
After you confirmed the location the key pair is stored you are asked to enter a passphrase. That is your password for every system your public key of the pair is stored.
At the time of writing the default length of the key is 2048 bit.

After installing InfraRecorder on Windows 10 it will only start once. After that the InfraRecorder UI will not show up. When you take a look at the task manager you will see that an instance of InfraRecorder is running but no UI is present; killing the process and starting InfraRecorder anew will not solve the problem.
This is a known bug (#729) and at the moment the only workaround is manually deleting the settings.xml file from C:\Users\YourUserName\AppData\Roaming\InfraRecorder\ before each start of InfraRecorder.

> echo '1234' | rev | cut -c 2- | rev
As cut can only remove the characters from the beginning of the string we have to pipe the string through rev first to reverse the order of the characters. Then we remove the first character with cut and reverse the string to its prior order.

When I wanted to remove a repository earlier today on Linux Mint I went with the usual add-apt-repository –remove. Linux Mint bases on Ubuntu LTS I thought removing a ppa is handled the same way as on Ubuntu. But I was wrong. Continue reading
I really love the Karak Wraith; the sound, the handling and the looks. It is not an end-game (Void T4 missions) weapon but I enjoy it nonetheless for everything else that is not defensive. Here are my battle-proven status builds for the different fractions. I used one orikon reactor and 5 formas (4 V, 1 -) to get the maximum out of it. Depending on your Warframe I suggest also using Rifle Amp aura mod that gives an additional 27% base damage increase. Continue reading
