I’m not sure from what version it started, but in Windows 11, the Disk Cleanup tool has been significantly improved and become much smarter. The key is that it’s an official tool, so it won’t accidentally delete files, won’t have ads, won’t have pop-ups, won’t have background processes, or any unnecessary elements. You can access the Disk Cleanup tool in Windows 11 by going to Settings > System > Storage > Temporary Files.

Deploying Docker on domestic servers, after deployment, if the company doesn’t provide a registry center, the first thing developers need to do is configure a domestic registry mirror address. It’s lucky that today there was a server configured with a registry mirror address, but when pulling images, it kept failing to pull. Error response from daemon: “https://registry-1.docker.io/v2/”: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers) Troubleshooting and Repair Attempts Initially, we attempted to switch to alternative mirror acceleration addresses, hoping to resolve the issue.

CentOS Stream is the upstream open-source development platform prior to Red Hat’s Linux distribution. I first noticed the open-source operating system lifecycle redhat and centos life cycle had ended, and I was wondering what was going on. Besides security issues, dnf wasn’t working, and I recently encountered failures when installing tools – checking the repository sources revealed that CentOS 8 Stream had reached its end of life. CentOS Stream Introduction Positioning and Roles CentOS Stream sits between Fedora Linux (upstream development) and RHEL (Red Hat Enterprise Linux, downstream development), acting as a bridge.

Browsing through the historical commit records, the site has undergone numerous theme switches. Each theme switch involved some custom modifications, and this is where I’m documenting the approach to customizing themes. My Github repository briefly maintained the even theme, but due to my obsessive-compulsive tendencies, I resisted upgrading the hugo compiler to the latest version, which resulted in incompatibility with the even theme, so I switched back to the stack theme.

In the history of C++ development projects, we utilized a custom protocol for communication, which employed a two-dimensional array pattern. When processing large volumes of data, the protocol required iterating through the arrays and performing serialization operations to generate logs. Due to its low efficiency, this resulted in noticeable lag or stuttering within the system under heavy load, as reported by the business departments. Problem Identification When troubleshooting the issue, we first performed a performance analysis of the system and discovered that CPU utilization increased significantly when processing large amounts of data, and system response times became longer.

In C++, lambda expressions are a convenient way to create anonymous functions that can capture external variables and use them within their bodies. This makes lambdas a flexible programming tool. However, the lifetime of parameters in a lambda expression is an aspect that requires careful attention, especially when capturing and passing parameters. 1. Lambda Expression Parameter Lifetime The lifetime of parameters in a lambda expression is typically the same as that of other C++ functions.

Picking up where we left off, I discovered that GitHub had an update, which was a little exciting. The customer service team said the issue with the driver not loading properly was resolved. However, after going through all of this – reinstalling and uninstalling – it still wasn’t working correctly. Background Continuing to contact customer service to inquire about a resolution, I was informed that

If you completely don’t understand these things, contacting official customer service first will also avoid wasting several hours. Main Text Recently, the C drive on my desktop computer, which I use for development, had run out of space. I specially took out a 256GB semi-retired solid state hard drive and used it as the C drive. Unfortunately, I kept messing around with it. Since moving to Shanghai, I’ve been busy with various things, and last week I finally took some time to reinstall the system.
