Some very cool stuff in daVinci resolve
On windows 11, the document type I create the most through right click / new menu is the text document, Today, i click in a folder, and it is missing, and in its place was a bunch of open office document types !
Turns out to bring it back I have to put the following text in a .reg file and run it, then restart explorer or windows
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.txt\ShellNew]
"ItemName"=hex(2):40,00,25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,6e,00,6f,00,74,00,65,00,70,00,61,00,64,00,2e,00,65,00,78,00,65,00,2c,00,2d,00,34,00,37,00,30,00,00,00
"NullFile"=""
[HKEY_CLASSES_ROOT\txtfilelegacy]
@="Text Document"
But now since I am here, I want to also add a new => html file to that very menu
1- Create a file called (template.html) ideally you would want to save it in %Allusersprofile%\Templates
, in my case the explicit location would be “C:\ProgramData\Templates”, but you will probably get an access denied error, to spare you the hassle of working around that, you can simply create a new folder inside C:\ProgramData\ called ExtraTemplates and store the file there
Now, put the following in a reg file and run it
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.html\ShellNew]
"FileName"="%Allusersprofile%
\ExtraTemplates\html.html"
Enjoy
re-enabling the old pre windows 11 context menu (Mouse right click menu) is as simple as running the following command in your terminal
reg.exe add "HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32" /f /ve
You obviously need to restart explorer, or your PC after this, but there is nothing more to it, short and simple
In windows 11 the complete context menu is available through the “show more options” option in the new menu, the new menu is a subset of the old, so why not have the old pop up from the word go
Enjoy your windows 11 with a windows 10 like context menu 😉

If you are looking for functionality similar to notepad++ functionality of replacing a string in all the files in a certain folder, Look no more, in linux this is a simple command
Assuming you are on the command line and the directory containing the files is the active one (cd)
the following line will replace foo with bar in all files on the current root directory but not in subdirectories
sed -i -- 's/foo/bar/g' *
If you want it to go recursively into sub directories, you can combine the above with the find command
find . -type f -exec sed -i 's/foo/bar/g' {} +
if you want sed to backup the files before it does the replace, use the following command, you can replace the .bak with anything you like
sed -i.bak -- 's/foo/bar/g' *
Many modern SD cards support the trim command () in Linux, the problem is that not many SD card readers (Mostly USB) do
So running () on a mounted card will usually return an error such as
fstrim -v /hds/usb
fstrim: /hds/usb: the discard operation is not supported
The command “lsblk –discard /dev/sdf” should tell you whether your SD card/adapter combination support trim right now, so the failure of the fstrim command above can be predicted in advance with this command
Now, assuming your SD card is not mounted, and you need to format it, Will formatting restore the speed ? unfortunately not, to restore the speed, before formatting your SD card, you might want to run the blkdiscard
function, mind you, this command will delete all your data !
blkdiscard -f /dev/sdf
but even that might not work
blkdiscard: Operation forced, data will be lost!
blkdiscard: /dev/sdf: BLKDISCARD ioctl failed: Operation not supported
2 pin connector TS (tip, sleeve)
3 pin connectors, TRS (tip, ring, sleeve)
4 pin connectors, TRRS (tip, ring, ring, sleeve)
Two standards exist for TRRS (4 Pin)
CTIA, which you can think of as apple, and i will call it apple throughout the post to help you focus on what matters, and OMTP, Which is everything else which i will call Android from here on.
For android (And almost any non apple device), the sleeve (Pin closest to the wire) is the ground, and the ring right above it would be the microphone… the other ring and the tip are the two speakers, right and left, In apple’s setup, the ground and microphone are switched together !
In a 3 pin connector (TRS), When it is meant to carry microphone signal, the tip is the microphone signal, the sleeve is still the ground, and the ring may carry any other signal such as a single speaker channel.
A nice adapter that has both input and output is this which i got from AliExpress (Photos at the bottom)
This 4K dummy adapter seems to support all resolutions up to 60Hz refresh rate, with the exception of 4K which works at a maximum of 30Hz (Probably due to signal attenuation)
There are many uses for this dummy adapter, one of them is “Sunshine and moonlight remote desktop”, another is using your GPU for processing while you are away (Nvidia won’t allow it if you don’t have a monitor connected and switched on), and most importantly TO ME, My video switch since I use multiple machines on the same monitor.
What this adapter is in reality is an eeprom chip that has the EDID data of a monitor with a very high refresh rate (120 hz), namely a fictitious monitor named AOC 28E850, If you want to make sure that this works with your monitor, it needs to be flashed with your monitor’s EDID.
If your monitor supports 4K at 60hz, you need to keep everything in that copy, and remove the 4K.60Hz from the list
If you want the modified file that originated from my LG 27UL550 and was modified to remove the 60Hz from the list of supported configurations, meaning I removed the 60 FPS from the 4K DTD, then here it is, just download it and flash it (Flashing instructions below) I also changed the monitor’s name just in case some systems might cache it’s details…
1- Find out the port on your graphics card that your monitor is connected to
2- Copy the EDID data from your monitor
3- Edit the data to remove the 4K/60 fps
4- Burn the data onto the adapter
To do that, there are many tools, one thing to note is that edid-rw did not work using my laptop which has a 9400mx, but worked just fine using an old PC i have with a “GT218 [GeForce 210]”, the error on the laptop reads
sudo ./edid-rw 5
Traceback (most recent call last):
File “./edid-rw”, line 131, in
main()
File “./edid-rw”, line 119, in main

IOError: [Errno 110] Connection timed out
edid-rw tool: https://github.com/bulletmark/edid-rw
wxedid tool: install from debian repo
I personally used the tools above to read/write/edit, but if you have access to a windows machine, AW-EDID should be the best tool for editing….
Analog Way EDID editor: https://www.analogway.com/apac/products/software-tools/aw-edid-editor/
So, let’s get down to that voodoo business !
1- There seems to be a very cool python script (tool) called edid-rw, let us install it’s prerequisites
sudo apt-get install python3-smbus edid-decode git
Now, you have python, let us download the tool, you can do that with the download button on github, I would rather just
git clone https://github.com/bulletmark/edid-rw
cd edid-rw
To begin with, you may need to run the following command to see what monitors are connected where, In my case, the monitor I want to copy (LG 4K 60FPS) is #5
xrandr --query
If this does not help, try the numbers and read the output to see which entry corresponds to the screen you want
sudo ./edid-rw 5 | edid-decode
Now that we have it, we can edit it with one of the software mentioned above, and dump it back on the dongle (The port number does not change, so put your number there and dump the data onto it)
udo ./edid-rw -w 5 < ~/edited_lgedid.bin

The aluminum sleeve appears to be fully cosmetic, At least this is my impression as the plastic inside seems very hard, so it is unlikely that the aluminum is providing any support, and obviously is not functioning as any form of heat sink
When it comes to MP3 players, there is definitely no shortage, but finding a good one is a task
Here are the most popular one, each with it’s advantages and disadvantages
Open source: github
Available on google play and F-Droid
Elegant, plays music files and does not do much more
Appears to be written in Kotlin

id3 tags were meant to be a simple way to store metadata in MP3 files, slowly but steadily, things became a bit more complicated
Originally, ID3 tags were meta data near the end of a file, then ID3V2 came along, and meta tags were moved to the beginning (With an ID3V1 copy at the end added by most ID3 editors)
Album artwork is another complication, As it may be embedded in the file, An older method used to depend on keeping an image called “cover.jpg” in the folder where the file is stored.
You can also have “user-defined fields”, which can be helpful if you are developing a music player that has some novel ideas
ID3 tag information can be obtained from gnudb.org, MusicBrainz, Discogs, Amazon
