Local Development Pain: Why Can't You Delete `nul` Files? A Solution to the “Composite” File System Problem
In the daily work of software development, we often encounter tricky “minor issues” that seem simple but can consume us hours of valuable time. One such “disaster zone” is deleting specific files – particularly those generated unexpectedly by toolchains.
I encountered a “level-boss” problem: during local development, a file named nul inexplicably appeared in my project. I tried Windows Explorer, the CMD command line, but the system displayed “File not found” or “Cannot delete.
Command-line AI Coding Interaction
The convention is to open Trae and prepare to start coding, and a notification arrives: the Claude model has been shut down and cannot be used; it’s highly likely that it won’t be recovered. The official provided a compensation plan, increasing usage by 300 (as of January). Checking it out, as expected, Anthropic is following US regulations to prohibit domestic companies from continuing to use the Claude series models. I joined the trae Discord community and saw many people complaining about the shutdown of the Claude model – after all, most people came here for Claude.
KB5054156: Windows 11 version 25H2 Feature Update (Package Deployment Guide)
Updating the local Windows system installation package, it was found that version 25H2 has been released. The local system is still stuck on version 24H2. Microsoft’s update patches have been installed, but the local system hasn’t upgraded to version 25H2 yet. Curious about what steps were missing in between.
This article is based on Microsoft official support documentation, outlining the core information of KB5054156 update to help users understand the key points for upgrading from Windows 11 24H2 to 25H2.
💻 Computer Black Screen Troubleshooting Log
My desktop computer is always kept on. Usually, I only turn off the monitor when I leave or don’t use it at night.
🚨 Problem Description After a routine operation, I discovered that the display was consistently in a black screen state. Attempting to power cycle the monitor, the screen still displayed “No Signal Input”. Using UU Remote Control to view the status, I found that both the desktop PC and another mini host were showing as online, indicating that the host itself may not have been shut down.
All the gifts of AI have already been marked up with prices in the shadows.
The frequency of article releases has noticeably increased with the use of AI, and I intend to differentiate this in the tags within the text as well. The author’s column will also note the names of large models. However, the issue persists: articles generated by AI have significantly reduced my level of involvement, with many articles being forgotten after a month or so.
C++23 introduces new features enumerate and ranges
Optimizing performance for a hot function involves the bulk of the time spent within internal loops. AI suggested using enumerate and ranges, so I consulted some related documentation. The main content of the article was generated by AI, and I tested the code and added some supplementary explanations. Online Compiler – testing C++ code inevitably involves our old friend. On gcc13, traditional for loops were slightly faster than std::views::enumerate, which
Memory timing C36, C30, and C28 – what do these mean? Which one is more suitable at a frequency of 6000MHz?
When assembling or upgrading a computer, we often see memory modules labeled with parameters like “DDR5-6000 CL36” and “DDR5-6000 CL30.” The “6000” represents the memory frequency (MHz), while “CL36” and “CL30” are abbreviations for “CAS Latency,” which is commonly referred to as “timings.”
So, what’s the difference between C36, C30, and C28? How do they affect performance when frequencies are the same? And how should you choose? Let’s discuss this topic in detail today.
Desktop Boot Loader Failure
In July, on a whim, with nothing better to do over the weekend, I decided to clean out the dust from my desktop PC – it hadn’t been cleaned in four or five years, and there was definitely quite a lot of dust accumulated. After cleaning it, I restarted the system, and everything worked perfectly fine. The computer wasn’t turned off regularly; it was left
