Server Status OLED Display Displayinator v1.0 This is a device you can shove into a spare USB connector on say a server rack system to display info like IP/Hostname/etc. It has an accelerometer so it can determine orientation (for racks which have sideways USB) and a simple font compression selection so it can dynamically fit information on one line.

BACK TO: Server Status OLED Display USBasp: To firmware upgrade or not? A lot of these chinese USBasp units are based on Thomas Fischl's design. But they all originally had problems related to clock speed when programming larger micros (A classic example is the ATMEGA2560). Two groups solved the problem independently, the open source folks added a flag to set a specific CLK frequency (that you'd nudge up and down to find the sweet spot) and the chinese wrote a autodetect feature to find the…

I was having stuttering problems playing some mp4 files (e.g. 4K 4:2:2 10-bit AVC) in windows on vlc and windows media player. The files played back smoothly in Davinci Resolve so it was a codec issue. I had disabled Windows Store so the default way of installing the codec wouldn't work for me.

Installing WSL Ubuntu w/ LAMP for Key Note: WSL works on Windows 10 (>=2004) and Windows 11. For older versions reference the MS docs LAMP commonly refers to Linux, Apache, Mysql & PHP, which was a common web development stack a few years ago. There are newer, more modern replacements for each component but each alternative adds complexity. I recommend exploring these replacements AFTER you've mastered the basic LAMP stack.
