ASUS ROG STRIX B450-E GAMING - No bluetooth after firmware upgrade

Sun, 29 Dec 2024 00:00:00 +0100

I upgraded the firmware(bios/UEFI) of my motherboard, the ASUS ROG STRIX B450-E GAMING, and after that the bluetooth adapter was not available in both Windows and Linux. I spent several hours debugging, but after i dropped into a Reddit thread concerning another ASUS motherboard, I found the solution.

I had to shutdown the computer, and pull out the power cord. After waiting 5 minutes, I put it back in and booted the computer.

Bluetooth was back...

WHO KNEW "Have you tried turning it off and on again?" would actually be the answer?!?!

PS: I assume the cord pulling and waiting is the important part, making sure the system is completely without power.

Get correct icon in rEFInd

Sat, 28 Dec 2024 00:00:00 +0100

Rename git master branch to main

Thu, 01 Apr 2021 00:00:00 +0200

How to rename old repository master branch to main.

Rename local branch

SHELL

$ git branch -m master main

Push new `main` branch to origin

SHELL

$ git push -u origin main

Delete old master branch

If old master isn't the defaultbranch on the remote

SHELL

$ git push origin --delete master

If you get an error, this step needs to be done manually on the remote, as main needs to be set as defaultbefore deleting the old master.

Prevent double initializations of views

Wed, 31 Mar 2021 00:00:00 +0200

It is best practice to not have the same view as both root view, and target of blank route. Using it for both, causes it to initialize twice.

SAP GUI for Java - Connection strings

Sat, 27 Mar 2021 00:00:00 +0100

The way you define a new SAP Connection in SAP GUI For Java differs slightly from SAP GUI For Windows. Let’s assume that you have the following connection information:

Address: 10.1.3.40 System No: 02 In SAP GUI For Java, you need to get to the “Advanced” tab, click “Expert mode” and enter the following connection string:

TEXT

conn=/H/10.1.3.40/S/3202

Obviously, the address goes between /H/ and /S/ and the system number goes to the end of the string. If your system ID is 00, you need to enter 3200. If your system ID is 07, you need to enter 3207. In our case, your system ID is 02 so you need to enter 3202.
