Restore Pretzel Rocks Offscreen Window

As you might now, I use Pretzel as the source for music during my streams. What you probably don’t know, for whatever reason, the player windows seem to disappear from time to time without any possibility to get it back on any of my screens.

Pretzl App Window as it should be

Actually, there is no way to get the window back on your screen(s). The easiest way to restore the default windows position is to jump into %APPDATA%/PretzelDesktop where you delete the window-state.json file.

This one has to go…

Make sure Pretzel is closed while deleting the JSON-file. Once you start Pretzel App again, it should reset its position.

Emoji Font

Occasionally (probably too often), I use emojis in my lecture notes. Unfortunately, sometimes I end up with strange things based on the font, I use.

OpenSansEmoji might help to solve this issue.

Example of OpenSansEmoji vs Arial

It is a font made of three other fonts, providing all most of the emojis you need.

This is basically a mashup font which consists of three fonts. The aim of OpenSansEmoji is to include the whole iOS (currently 6.1) Emoji set while keeping the file size as low as possible. Most of the symbols listed on the “Emoji” Wikipedia page are supported. All symbols are in monochrome.

Also, it is licensed under Apache 2.0 and therefore free to use.


Raspi Network Failure Shenanigan

It seems as I run into a common issue with my Raspberry 4. After an indeterministic uptime, the wifi stops working.

And here is the hotfix, a small script provided by @pitto first restarting the nic and if anything fails just reboots the device:

This bash script checks for wireless internet connection and, if it is failing, tries to fix it.

It is simple and it seems to work.

I just have to write some automation to roll it out automatically including a corresponding cron job once I find some time.

Turn off your Screen in Windows 10

A problem you might have as well: how to turn off the screen of your laptop without changing the battery settings and without using any tools? Probably using a hotkey? Did you realize, this is not part of Windows at all?

Basically, here is the batch file you have to create for it. Yes, someone wrote a batch file for this. Create a shortcut to the batch file, assign a hotkey and be happy. You also can download the batch file from TechNet. Works on my machine (with Windows 10).

Glow Effect for SynthWave’84 on macOS

During today’s recording of our podcast, I talked about not getting the glow effect for the SynthWave’84 theme working. Right after doing so, I figured out how to solve the issue.

After installing the plugin, you need also the extension Custom CSS and JS Loader.

Now edit the settings in the settings.json file of Visual Studio Code by adding the following entries:

"vscode_custom_css.policy": true,
"vscode_custom_css.imports": [

Of course, you have to change the user name above to yours. The settings.json should now look quite similar to the following:

Eventually, you need to make sure Visual Studio can apply the modifications by running

>sudo chown -R $(whoami) "/Applications/Visual Studio"

That is, by the way, the step I have missed in my previous attempts.

Now you can restart Visual Studio Code, enter Command+Shift+P and enter Enable Custom CSS and JS

Once Visual Studio Code is reloaded, the glow effect of the theme should work like a charm.

If you receive any message about a corrupt Code installation, you might want to simply click it away.

Some of the previous steps might need to be repeated once the Visual Studio Code installation was updated to a new version.

Raspberry Pi – Setting a static IPv4 address

It run me mad, as I tried to change the IP address of my Raspberry to a static one. I changed literally everything in  /etc/network/interfaces and reloaded, restarted and reboot the device over and over.

iface eth0 inet static
gateway 192.168.0.

As the above configuration did not help a lot, I figured out that based on the Raspberry model, you need to change settings on various places.

First run

cat /proc/cpuinfo

to determine you model. While getting something like

pi@raspberrypi:~ $ cat /proc/cpuinfo
processor    : 0
model name    : ARMv6-compatible processor rev 7 (v6l)
BogoMIPS    : 2.00
Features    : half thumb fastmult vfp edsp java tls
CPU implementer    : 0x41
CPU architecture: 7
CPU variant    : 0x0
CPU part    : 0xb76
CPU revision    : 7

Hardware    : BCM2708
Revision    : 0004
Serial        : 000000004715b608

you need to use the hardware revision and

Model and Pi Revision 256MB Hardware Revision Code from cpuinfo
Model B Revision 1.0 256MB 0002
Model B Revision 1.0 + ECN0001 (no fuses, D14 removed) 256MB 0003
Model B Revision 2.0
Mounting holes
256MB 0004
Model A
Mounting holes
256MB 0007
Model B Revision 2.0
Mounting holes
512MB 000d
Model B+ 512MB 0010
Compute Module 512MB 0011
Model A+ 256MB 0012
Pi 2 Model B 1GB a01041 (Sony, UK)
a21041 (Embest, China)
PiZero 512MB 900092

Based on this information you need

Model a

Static IP addresses in /etc/network/interfaces is not the “prefered” way,as it is an old way and DHCPCD5 is installed.

Model b

Static IP addresses are configured in the /etc/dhcpcd.conf and it is  required that /etc/network/interfaces is set to manually.

iface eth0 inet manual

That’s all…

Sud-o-Visual Studio Code

There are literally no good reasons to start Visual Studio Code on macOS with leveraged rights. Applications on macOS are not designed to run sudoed in general. If you would do so, this can have unintended sided effects. So much for the disclaimer.

If you want to start Visual Studio Code on macOS sudoed, just run

sudo open /Applications/Visual\ Studio\

That’s all.

How to get the favicon.ico from any Page

Recently, I was in the need of retrieving the favicon.ico file from a website. As I had to process the file programmatically and render it on a website, it would have been quite a lot of manual work to get the .ico file and make sure the browser does render it in the correct way. After digging around, I learned about a secret URI probably provided once by Google’s social bookmarking service Google Shared Stuff. While Google Shared Stuff was launched in 2007,  it was already discontinued in 2009. However, this one URI seems to work perfectly maybe because it is still used within Google extensively.

The Secret

To get the favicon.ico file from any arbitrary page you simply have to use an URI using the following pattern:

Eventually, this URI will provide you the following image: Image retrieved using

How it Works

Some More examples to see how it works:

  • Facebook
  • TechChrunch
  • aheil blog
  • Google
  • dotnetpro Magazine
  • Google+

As most of the sites do keep their favicon.ico file right in the root of the web site, others like Google don’t. Actually, you might find Google’s plus icon located at

While this is probably not a problem retrieving the favicon.ico file using the standard URI at all, the secret URI provides one major advantage: you’ll get the icon as a nice 16×16 PNG file, ready to be rendered in any <img> tag right away.

The Risk

As every time building up on a Google service as I did before, it might disappear tomorrow without notice leaving your site with quite a bunch of 404s though. Even worse, as it seems there is no official support for this URI, there won’t be any notice or deprecation period until switched of as done for other services like Feedburner.

Visual Studio 2012 Upper Case Menus

I am probably the last person in the .NET community who figured out how to disable the Visual Studio 2012 Metro design upper case menus. I haven’t had a chance to work a lot with Dev11 yet, so I was not bothered too much by the new design. After working a couple of hours with the new IDE, I was quite annoyed by the new upper case menus.

It seems that Richard Blanks was the first who figured out how to disable the upper case menus in VS 2012, looking nice and capitalized.

Visual Studio 2012 Capitalized Menus

As I love to do things automatically when possible and hate to fiddle with the Registry Editor, I set up the registry key to change in a small script. Just rename it to .reg and double click the file.

Windows Registry Editor Version 5.00

If you create the file manually, keep mind to save it in ANSI encoding, as Unicode scripts are not merged at all.

Deutsche Rechtschreibung im Windows Live Writer

Windows Live Writer dürfte auf der Windows Plattform derzeit eines der beliebtesten Blogging-Tools sein. Mit Anbindung an die meisten Blogging-Plattformen und zahlreichen Plug-Ins lässt das Tool kaum wünsche offen. Allerdings ist bisher keine deutsche Rechtschreibprüfung vorhanden. Anstelle dessen konnten unterschiedlichste English-Derivate (es gibt eben Englisch und Englisch) ausgewählt werden. Die Möglichkeit die deutsche Rechtschreibkorrektur zu aktivieren oder eine zusätzliche Sprache hinzuzufügen fehlt bisher gänzlich.

Die Lösung ist recht jedoch einfach. Vorausgesetz auf der betreffenden Maschine ist Office 2010 (32-bit) mit deutscher Rechtschreibkorrektur installiert. Ein Blick in den Ordner

C:\Program Files (x86)\Microsoft Office\Office14\PROOF

sollte Gewissheit verschaffen. Hier gilt es die Dateien


in den Ordner

C:\Program Files (x86)\Windows Live Writer\Dictionaries

zu kopieren. Nach einem Neustart von Windows Live Writer sollte nun unter Options / Spelling auch der Eintrag German (Reform).
