I have two Sensei Raw mouses, one is 5 years and the other one is 7 years. Because the older one generates a high pitch sound from the sensor which is quite annoying I am thinking of buying a new one. However, the Raw is discontinued. Then I ordered the Sensei Ten.
With a new optical sensor, the Sensei Ten does not have the noise. The shape of Ten is the same as that of Raw. But I feel the quality of Ten is lower than that of Raw. First, the button is quite rough (Button 4-8), like a 10 euro cheap mouse. Second, buttons 1 and 2 are stiffer and a little bit laud when clicked(maybe because it is so new). Third, the cable skin is made of rubber which is not braided anymore and it is easier to be broken. Fourth, the wheel is not as smooth as before and the harder rubber on the wheel is not comfortable to touch compared to the previous one. One advantage of the new one is the RGB light, however, the log is painted with dots anymore (I prefer the dots).
more comparisons can be found in reference 
After one month, the Sensei Ten generates some noise from the wheel. The light of the wheel will turn red when gaming.
Al2O3 (aluminum dioxide) has a high band gap 9 eV, a high breakdown electric field 5–30 MV/cm,7 a high relative permittivity 8.6–10, high thermal stability up to at least 1000 °C, and remains amor- phous under typical processing conditions. 
PVC (Polyvinyl chloride (PVC)) ‘s use as an electrical tape backing is largely due to its dielectric strength, which can reach nearly 60 MV/cm depending on material composition. Dielectric breakdown is the voltage limit above which a short circuit may occur across the tape. 
PET (polyethylene terephthalate) has a relative permittivity 2.1-3.5.

Today, my colleague create a file in the shared folder named “x bb .txt” via Nextcloud. Originally, I thought there is something wrong with my computer. Scan my system for several hours, nothing was detected. Later, I notice there is a warning notification from Nextcloud, it said because of the limitation of the windows system in the filename, I cannot synchronize the file. Then I renamed the file, and everything becomes normal again. It is also noticed that if there is such a file in a zip file, unzipping the file to a specific folder will not work.
The point is my colleague using mac os and I am using windows. The rules for naming files are not identical.
Windows doesn’t allow these characters in filenames:
Recently I use google docs for teamwork. However, because the original file is made of Microsoft Office Word, there are several issues that some information/feature lost when I save the file with google docs.
The number of the title will not display in google doc.
2. The personal format of text will not take effect in google docs.
open in Google Docs, my personal format is removed/lost.
3. The color and format of table in google doc is different in Microsoft Word
4, the Equation from MathType is not correct but still readable and can be normal again in Microsoft Word. You will lose all the numbers of equations.
Recently, I bought the EA play membership and have tried a few games. Here I will give some comments of the game. Here I just give the comments.
Battlefieldseries. Battlefield 1 and 5 has the best picture quality and the campaigns are also good. The battle with tanks and planes are quite cool. Aside from these two, the picture qualities of the other seires are just soso because of the early release (>5 years ago). Battlefield hardline is not recommed, bored in play. Battlefield Bad company 2, amazing.
Plants vs. Zombies. Good games to relax. The classic 2D one does not have a high resolution setting not suitable for 4k monitor. The 3D ones (Garden warfare, GW2 and Battle for Neighborville) are simillar with good picture quality and cute charaters. The Neighborville has more characters and the nut is the best one to me, funny to play.
Sea of Solitude. The sunny scence is beautiful but the black one is not comfortable to me. The game is not recommended because of the dark style. Aslo like the name of the game, you will fell bad for the story (quarrel between parents, campus bullying) during playing the game. Don’t play this in the evening.
Titanfall2. Excellent game, best mecha game. Nice story and the way to play. The only drawback is the unstable server of EA so that you are not sure wethere you can play the online game or not.
Mass effect. Not finished yet, but the story is cool from others’ review. The picture quality of 1 is so so and not attractive to me. 2 and 3 are better and look relative good.
Crysis remastered. Have not played yet. The picture quality is not as cool as I expected.
Need for speed. A car game. Even though the new ones have better picture quality but my favourite one of this series is “need for Speed Most Wanted (2005)” which is not avaible. Need for Speed™ Hot Pursuit Remastered is similar to Most Wanted (2005), good to play, the the access to free roam is enabled by pressing “L ctrl” in the career page.
Star War: Jedi: Fallen Order has about 20 hours to finish the main mission. It is funning to play as a Jedi. The game has a lot elements similar to Titan Fall 2 and Assassin’s Creed that Jedi is able to run on the wall and climb on the wall.
Xbox Game Pass
Halo Infinite. It takes about 10 hours to finish. Don’t have too much surprise. Some scenes are repeated again and again. The tank Scorpion is quite cool to play.
My hardware is Lenovo Legion 5 Pro 16 82JQ001PGE. AMD 5800H, 32 GB Ram, an external monitor, 4k resolution.
