I changed my phone from iPhone X to iPhone 13 Pro a few days ago. As a rule, I deleted all the Apple Pay cards and added them again. As a result, one of the Bank of China's Lotiani cards failed to be added all the time, and even the SMS verification code was not received. I directly prompted "This card has not been added, please contact the card issuer for more information", After several attempts, the prompt changes to "Invalid card information".

All the common methods on the Internet are invalid after they have been tried. It took several days to solve the problem, so we can record it and save time for future generations.

TL;DR : If your Windows XP installation on VirtualBox is extremely slow, try updating the VirtualBox version. If the guest addition cannot be installed normally, try to turn on 3D acceleration, increase video memory, and turn off the network.

In order to use the "extremely advanced" college entrance examination registration system developed in 2003 in our province, we need to run Windows XP in the virtual machine and then open IE6.

*In fact, the system runs normally on modern browsers, but the connected junk trading system of Agricultural Bank of China does not work on modern browsers, so the whole Windows XP has to be followed by Internet Explorer.

Get on the train

On February 9, I suddenly received a message that it was a promotional activity of Microsoft Education Mall. The official 8+128 version of the Surface Go generation is only 1169 yuan.

In fact, there was no desire to buy at the beginning. Generally speaking, the tablet with a price of about 1000 yuan is out of our consideration (brand new):

Tablets at this price generally shrink as they can, with poor appearance and feel, barely viewable screen parameters, and storage particles slower than your mobile phone. All of these will lead to a poor use experience. It is better not to buy.

At first, I thought the same way, but I checked the parameters. After all, it was a surface, not a surface, and the original price was more than 3000 yuan.

Moreover, the screen parameters are very pleasing, rounding 1080p, 400 nits brightness, 100% sRGB color gamut coverage, and the average $ Delta E_ {2000} $1.3. Instantly felt that there was no electronic garbage.

This is very cost-effective. Place an order immediately, and Microsoft will lose blood and make money (fog
