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.

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.

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).

The Ultimate Windows Server 2003 Media Hack

Doh, if you are going to use your Windows Server 2003 as a streaming server for your Xbox 360, you might be in trouble. For a while I went with a rather sophisticated solution, running a Windows XP Media Center within a Virtual Server on my Windows Server 2003. The solution is not the desired one and as Windows Media Center and the Media Center Extender within Xbox 360 have some trouble in streaming h.264 encoded movies files, I had to dig a bit deeper.

Before you go one, please be aware of the following disclaimer:

The following is given under a “works on my machine” premise. The proposed approach is based on my very personal attempts and comes a”as is”. If you try to attempt the following steps, you do it on your own risk. It is not supported by Microsoft, and hey, in case you brick your box don’t expect any support from Microsoft. Don’t blame it to me either as you did it on your own risk, but let me know as it could be fun, tough.

There are several ways to share media with your Xbox 360. The easiest ways is to check out After determining your OS, you will be guided through the best way to share media. Bad luck if you work on a Windows Server 2003, though. Not supported, you will be told.

The easiest way is to share media over Windows Media Player 11. Windows Server 2003 comes with Windows Media Player 10. But as we know the core of Windows Server 2003 is somehow Windows XP and therefore there must be away to install WMP 11 on Windows Server 2003. If you google for it, you will come along a dozen hacks and workarounds and most of them won’t work.  Recently, this guy called C:Amie posted some awesome hack C:Amie provided a new link to install Windows Media player 11 on Windows Server 2003. If you have time, go through it, if you are in a hurry, do it that way:

  1. Make sure your box is fully patched and Service Pack 2 is installed.
  2. Download Windows the Windows Media Player 11 installer for Windows XP.
  3. Download the automatic installer from C:Amie’s website.
  4. Run the automatic installer and extract it to any folder on your Windows Server 2003 box.
  5. Copy the previously downloaded wmp11-windowsxp-x86-enu.exe into the same directory.
  6. Go to the folder and run the INSTALL.CMD file.
  7. Follow the onscreen instructions.INSTALLER.CMDThe script creates a temporary folder on your C: drive called C:wmp11. There you have to change the compatibility mode of two files to Windows XP. Go to C:wmp11update1. and right click the update.exe file. Chose the Compatibility tab and check the Compatibility mode for Windows XP. Make the same for the update.exe file in c:wmp11update2.
    update.exe Properties Dialog
  8. Now go back to the command line window and press a key to continue and the simply wait.
  9. The software updater wills start after some time and after some more time you will end up with the UPnP for Windows Server 2003 dialog.UPnP for Windows Server 2003
    Check the Universal Plug and Play checkbox and select Next and then Finish.
  10. If everything went well, you will end up with Windows Media Player 11 on a Windows Server 2003. Hurray.Everything OK

But you remember that we want to stream h.264 encoded files to our Xbox 360, right? The good news is that Windows 7 will support h.264 natively. The bad news is that we work on a Windows Server 2003 right now.  With some work however, we can teach our Windows Server 2003 also to deal with h.264 encoded .mp4 files. All we have to do is to install some codecs and to apply some registry hacks.

  1. For the sake of simplicity, I took the K-Lite Mega Codec pack. It took the mega pack instead of the standard pack because Dirty Harry is using a .44 and not a .375. This might be reason enough.
  2. During installation select Profile 2. It’s the default profile without the players (you remember we want to stream anyway). Feel free to experiment with other profiles and custom settings.K-Lite Mega Codec Pack Setup Dialog
  3. When you come along the Select Additional Task step, don’t forget to scroll down and to check Make thumbnail generation possible for the following types. This will create the thumbnails in the Windows explorer and within the Windows Media Player 11.
    K-Lite Mega Code Pack Setup Dialog - Additional Tasks

At this point your Windows Media Player can play h.264 encoded files but your server is still not capable to share any kind of .mp4 files. They won’t show up in the folders monitored by Media Player until we apply some tweaks to the registry.

On my crusade I came along two registry patches. It seems that they did not work for everybody, however, nobody tried on Windows Server 2003. It worked for me after I installed bot
h of them.

  1. Download the first registry patch, rename to .reg and install it.
  2. Download the second registry patch, rename to .reg and install it.
  3. Reboot to apply the registry changes.

Now, out Windows Server 2003 is capable to stream h.264 encoded media files. The previous patches will now cause that Windows Media Player 11 will add all kinds of .mp4 or .m4a files within the monitored folders. Adding these folders to be streamed is straight forward.

  1. Go to  Libary /Add to Library…Windows Media Player 11 - Library Menu
  2. Add all kinds of folders that should be streamed to your Xbox 360. The media types will be organized automatically, so movies, music files and images will be shown in the corresponding tabs in the NXE.Add to Library Dialog
  3. In some rare cases (and I know what I am talking about as I encountered this rare case) all your mp4 files won’t show up in the movie folders. In this case select Library / Other and check if the files are shown there.Windows Media Player 11 - Other  MediaIf you find all your files here, something went terrible wrong with your media library. Calm down, there is a easy workaround (FWIW: if you already share media, stop sharing as the following won’t work).Go to C:Documents and Settings[YouProfileName]Local SettingsApplication DataMicrosoft and delete the Media Player folder. This will wipe out the whole media library for this computer. Restart from 1. and everything should be green now.Media Player Library

Now, where everything is nicely organized, indexed and monitored, we are ready to share our media with the Xbox 360.

  1. Turn on your Xbox 360.No kidding, you won’t be able to turn on sharing if the 360 is not on at that point of time.
  2. Go to Library / Media Sharing…Media Sharing
  3. Now it’s straight forward:a) Check Share my media to b) Select your Xbox 360c) Click AllowMedia Sharing Dialog
  4. Finally, don’t forget to check out the Customize button which will open a dialog for some more fine tuning (what kinds of media to share, what ratings to share, etc.)

Now got to your Xbox 360 and enjoy your h.264 streamed media.

There are a few point’s I haven’t found out how to resolve, yet.

  1. The registry hacks don’t include .mkv file extensions. Also both hacks could be combined into one. I simply haven’t spend time in this yet.
  2. The 360 won’t show any thumbnails for the h.264 encoded files. Not sure if this is related to the XNE or the Media Player. This might worth some more investigation.
  3. The 360 does not show the length of the media file. It does so for .avi files, so this might be automatically answered once 2. is answered.


High-Res Skype

Go and get some good webcam (I use the Microsoft LifeChat NX-6000), navigate to the Skype user settings

 C:\Program Files\Users\[YourWindowsProfile]\AppData\Roaming\Skype\[YourSkypeProfile]

open config.xml and follow the instruction by Phillip Torrone, seeking for the <Video> tag. I am using Skype version and the configuration file looks quite different now. However, adding the <CaptureWidth> and <CaptureHeight> tag works fine as well with this version since it was especially introduced with version 3.6. At the end your configuration file should look similar to this one.

I re-started Skype and it looks like the other side can see me in 640×480 now.
