Linux Mint on Thinkpad L450 - Graphics Drivers

To get a "Intel Broadwell-U Integrated Graphics" working I had to run:

sudo apt-add-repository ppa:xorg-edgers/ppa
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
sudo reboot

Solution from here

Reload Chrome with xdotool

I found it to be rather tedious to switch between vim and my browser just to refresh it. Sure, there are some extensions to auto-reload on file change. But what happens if you're change, say, the database?

Come on, it's way cooler to do this on a keyboard shortcut.

xdotool search --onlyvisible --class "Chrome" windowfocus key 'ctrl+r'

See screenshot for an example how to register a global shortcut in Linux Mint.

Extended version:

I extended the script with a "switch the focus back to the last window".


focused_window_id=$(xdotool getwindowfocus)                             # remember current window
xdotool search --onlyvisible --class "Chrome" windowfocus key 'ctrl+r'  # send keystroke to refresh
xdotool windowactivate --sync $focused_window_id                        # switch window, sync to "wait"

Why move to ZSH

  • Have found this great article today and would like to share it with you guys ( and archive it here ).
  • Super easy installation with oh my zsh.

Network fails on a fresh Ubuntu Clone

Short: The System remembers its old MAC address, remove it so it knows where to bind eth0 to.

sudo vim /etc/udev/rules.d/70-persistent-net.rules

remove "your old MAC addresses", and change your "new one" to eth0.

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:fb:d5:1e", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:fb:d5:1c", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"


dist-upgrade on Ubuntu XEN Guests

Short: Don't even think about it.

Fuck it. I tried to migrate several Ubuntu Hardy maschines (XEN guests) in the past view months. Since, yeah - you know: it's an unsupported LTS. The first broke due to an interupted SSH connection. Yeap, they warned me. My fault.

Then I got smarter, and upgraded trough a SSH connection to the XEN host which then connected (somehow) to serial port. Upgrade seemed (always) to go fine. Took a while and a lot of "NO dont modify my config file". In 4 cases the upgrade went through, requested a reboot and was gone for good. In 2 cases it stopped at "copying image-something from somewhere" (I guess the XEN host tried to get the linux image).

Screw it, I'll keep running Ubuntu 8-something Hardy for good. I guess backing-up, reinstalling and reconfiguring the whole thing would go a lot faster and safer.

Is this just a problem for me, or a bonkers (Xen?)-Setup (at Strato)? Don't get me wrong, I quite enjoy their (recently abandoned) Multiservers. Got three of them w/ 21 systems running perfectly smooth.

Now What?

So, this Blog is essentially dead. I made it roughly one year ( last post was March '13 ) without even thinking of posting here.

First of all: Changing the Software to Jekyll is to cut out any tasks concerning my servers security. ( Wordpress Updates )

Second: I like this domain, I like the idea of having a blog. I'm - well - just unsure what to do with it.

Technology / Programming / Games:

I'm at least 2 years to late for most things that I'd like to share. The brief time I have for gaming is reserved for gaming. I have not the slightest of interests to put my opinion on the latest crap from (for example) Samsung on here.

Private stuff

... is kinda a notorious thing to do on the internet - nobody wants to know how and what I do - and nobody needs to know :-)

So what now?

For about 3 years now I'm "working" (a few hours a month) on a game. If I find myself with something more than 100-ish prototypes that nothing look like something someone expects from a game, I'd be happy to share.

I'll get back to that at some point :-)

Goodbye Wordpress. Hello Jekyll!

So long and thanks for all the fish

I used Wordpress almost for 10 Years now ( For memories click here ). It was comfortable, set up pretty quick, for everything you could find a plugin dnd there were a lot of gorgeous themes around.

I never had serious problems - well, even then, I was able to fix them since it's documented very good and the code is not that hard to read.

Wordpress has grown a lot. It's still growing from Blogplatform to become a CMS. I had increased problems with overall speed and it felt not that responsive anymore.

Why the Jekyll ?

Jekyll is nothing like Wordpress or any other popular Blogsoftware out there. It is essentially a "generator" for good old static html files. And yes, it kinda feels like a step backwards. No database, no "shortcodes", no Uploader, no Filebrowser, no Search, no Login ( I could continue ).

Jekyll is a simple, blog aware, static site generator. It takes a template directory [...] and spits out a complete, static website suitable for serving with Apache or your favorite web server. This is also the engine behind GitHub Pages, which you can use to host your project’s page or blog right here from GitHub.

Why would anybody choose that?

  • For somebody who spends most of his time between a terminal, vi and git this is quite appealing.
  • Have you ever tried 'hacking' a static html page?
  • Try a benchmark. I dare you


  • "No dynamic content" (1)

    • => Nowadays Javascript is always an option.
    • => Static HTTP Pages can be included in every "dynamic" application
    • => (NodeJS, Ruby (on rails), PHP etc.)
  • More work

    • => Yeah. No. Id say "more control"
  • Not for beginners.

    • => Beginners are still reading this? Get lost. Seriously

If anybody wonders, this is the "Hyde"-Theme. Modified a bit
