Conclusion of the next stage of the DePIN track At the end of May, ICN (ImpossibleCloudNetwork) @ICN_Protocol announced that it had received strategic investment in NGPCapital with a valuation of US$470 million. Many people's first reaction was: "Has Xiaomi invested in Web3?" Although this was not Lei Jun's direct move, the one who had bet on Xiaomi, Helium, and WorkFusion

The computer is stuck in the "Undo Changes made to the computer" interface, which is a common problem after the Windows update fails. It is usually caused by the stuck rollback process and cannot enter the system normally. 1. First of all, you should wait patiently for a long enough time, especially after restarting, it may take more than 30 minutes to complete the rollback, and observe the hard disk light to determine whether it is still running. 2. If there is no progress for a long time, you can force shut down and enter the recovery environment (WinRE) multiple times, and try to start repair or system restore. 3. After entering safe mode, you can uninstall the most recent update records through the control panel. 4. Use the command prompt to execute the bootrec command in the recovery environment to repair the boot file, or run sfc/scannow to check the system file. 5. The last method is to use the "Reset this computer" function

Blockchain technology has spawned many independent networks, such as Ethereum, Binance Smart Chain, Polygon, etc. Each network has its own unique design and protocol. However, this independence also presents the challenge of difficult assets and information flowing freely between different chains. For example, ERC-20 tokens on Ethereum cannot be used directly on the Polygon network. In order to solve this isolation problem, cross-chain bridges emerged and became the key infrastructure to connect different blockchain networks.

The problem of slowing right-click menus is usually caused by extensions or third-party software loaded by the system. Solutions include troubleshooting plug-ins, optimizing settings, and uninstalling suspicious software. 1. Use the ShellExView tool to view and disable non-essential Shell extensions, and gradually test to find plug-ins that slow down the right-click menu; 2. For advanced users, you can lower the menu delay time to 0 or 200 milliseconds by modifying the MenuShowDelay key value in the registry to speed up the response speed, but you need to be careful to backup before operation to avoid causing system abnormalities; 3. Uninstall or update software that may cause conflicts such as old compression tools, screenshot software, antivirus software, etc., and observe whether the right-click menu returns to normal. If the problem is alleviated, it means that it is the performance problem caused by the software.

When encountering the "RPCserverisunavailable" problem, first confirm whether it is a local service exception or a network configuration problem. 1. Check and start the RPC service to ensure that its startup type is automatic. If it cannot be started, check the event log; 2. Check the network connection and firewall settings, test the firewall to turn off the firewall, check DNS resolution and network connectivity; 3. Run the sfc/scannow and DISM commands to repair the system files; 4. Check the group policy and domain controller status in the domain environment, and contact the IT department to assist in the processing. Gradually check it in sequence to locate and solve the problem.

Windows time inaccurate is mainly caused by abnormal network time synchronization or aging of CMOS batteries. Solutions include: 1. Check the "Internet Time" setting to ensure that synchronization is enabled and use time.windows.com or ntp.aliyun.com; 2. Modify the registry key RealTimeIsUniversal to 0 to correctly identify the BIOS time; 3. Replace the motherboard CMOS battery to avoid resetting time after power outage; 4. Turn off "Auto-adjust daylight saving time" or confirm that the time zone settings are accurate. The troubleshooting order is recommended to set the software first and then the hardware problem.

If the second monitor is not recognized by Windows, first check whether the cable and interface are normal, try to replace the HDMI, DP or VGA cable, confirm the plug-in video output port, and test different interfaces to eliminate compatibility issues; then verify the monitor power and input source settings, and connect the monitor separately to test whether it can be recognized; then enter the Windows display settings and click the "Detection" button, or use Win P to switch the display mode, and update the graphics card driver at the same time; finally check the graphics card specifications to confirm whether it supports multi-screen output to avoid exceeding its maximum output capability.

To manage Linux user groups, you need to master the operation of viewing, creating, deleting, modifying, and user attribute adjustment. To view user group information, you can use cat/etc/group or getentgroup, use groups [username] or id [username] to view the group to which the user belongs; use groupadd to create a group, and use groupdel to specify the GID; use groupdel to delete empty groups; use usermod-aG to add users to the group, and use usermod-g to modify the main group; use usermod-g to remove users from the group by editing /etc/group or using the vigr command; use groupmod-n (change name) or groupmod-g (change GID) to modify group properties, and remember to update the permissions of relevant files.
