01 Ultra HD ARM assembly instructions desktop wallpaper
ARM 32-bit Assembly Instructions Cheat Sheet, the new Arm 32-bit Assembly Cheat Sheet is now available in poster print and digital versions. If you like to print 24" x 36" posters directly, the author provides multiple resolution versions, which are also very cool to use as desktop wallpapers.
This cheat sheet is an expanded version of the ARM Assembly Basics cheat sheet . It covers registers, basic instructions, load and store instructions, conditional execution, branches, literal pools, PC-relative addressing, and a complete reverse shell in assembly.
There is also an ARMv8-A one with a resolution of 6000*3750, which is high enough.
The above high-definition wallpapers can be downloaded at azeria.gumroad.c remove the Chinese characters om/l/Arm-cheatsheet-2020-version, or you can reply to the ARM wallpaper download collection on the homepage of the Chip Home WeChat public account.
02 win11 virtual machine matryoshka contest
11 sets, 10 sets, 8.1 sets, 8 sets, and then Win7 . When we usually open a virtual machine, it will sometimes get stuck. After quadruple nesting, VMware pushed the nested virtualization function to the limit. We usually open several virtual machines. Most people open a Linux virtual machine, or open a Win10 virtual machine and disconnect the network drawing board
Facts have proved that as long as the nested virtualization is configured well and the allocated hardware resources are sufficient , it is no problem to carry out multi-level nesting. If developers are willing, they can actually continue to nest, including nesting such as Windows Vista and Windows XP. system.
Why is there no classic XP system? Win7 has been stuck and cannot be used anymore unless the hardware resources are upgraded, and it can be used again. Can anyone guess what the minimum configuration of this win11 computer is? How much memory do you need to start with?

This guy from San Francisco’s shed welding skills are absolutely top-notch, let’s take a look:
04 Resistor Cube
Just for appreciation, by the way, assuming the resistance of each electron is 10k, what is the resistance of the two blue points?
05 How electrons were born
How electronics were born is 
a very interesting production. If you can see where this idea comes from at a glance, it proves that this picture is successful.
06 Intel launches Thunderbolt 5 interface with speed up to 120Gbps
Intel has released Thunderbolt 5 technology and demonstrated it on prototype notebooks and docking stations, with bandwidth-boosting applications delivering transmission speeds of up to 120 Gbps.
Thunderbolt 5 will have bi-directional data transfer speeds. (bi-directional) up to 80 Gbps, and supports "bandwidth boost" usage for speeds up to 120 Gbps, supporting 2 8K resolution displays .
Thunderbolt 5 builds on Thunderbolt 4 with many improvements and features:
It has bi-directional data transfer speeds. (bi-directional) 2x faster for very intensive video applications, 3x faster with Bandwidth Boost (120 Gbps)
Provides 2x PCI Express data transfer speeds for faster storage and external graphics.
Compatible with USB4 V2, DisplayPort 2.1 and PCI Express Gen 4.
Data transfer speeds are twice as fast as Thunderbolt networks, allowing for faster computer-to-computer connections.
It uses PAM-3 signaling technology to improve the performance of circuit boards, connection ports, and passive cables up to 1 meter long (so live cables may not be needed to reach 80 Gbps speeds in USB4 V2... remains to be seen)"
Intel says the new Thunderbolt 5 standard will deliver the data transfer speeds content creators, gamers and professionals need. While Thunderbolt 4 is currently present in many mini PCs, Thunderbolt 5 may not be coming anytime soon. Until the price of 8K resolution displays drops, demand for faster storage and high-performance eGPUs will continue. This may also help stimulate adoption of this new standard. "Computers and accessories equipped with Thunderbolt 5 will be launched as soon as 2024.
07 Linux
Linux is designed for long-term use and continues to evolve through open source contributions . Linux was a small operating system when it was released in 1991. Over 30 years later, it has developed into an amazing operating system . However, other systems of that year slowly faded out of everyone’s sight.
Another picture comes to mind. I was still using Open Browser back then, but now I basically only use Google.
08 Wireless network card
I think it’s very interesting. Is there such a device? It can be plugged into the network port to have wireless network. If you think about it carefully, it’s just a router. It’s just small in size and doesn’t need to be plugged in. It would be great if there is such a device in the future.

This is what a 555 integrated circuit looks like when made with discrete components. The video shows the step-by-step process from breadboarding to the final build. The author is admirable.

10 Open Source E-ink Screen Calendar
ESP32-based, Portal-themed e-ink calendar that runs on AAA batteries for years and has optional weather integration via OpenWeatherMap.
https://github.com/wuspy/portal_calendarThe software is developed based on Arduino IDE or PlatformIO. The author has open sourced all the source code and the entire production process . You can copy it according to the link above . It is a very nice calendar work.
