The article argues that people who prefer command line interfaces over graphical admin interfaces are missing the point. While clickops and ssh may not be ideal for running a server, the author suggests that a server’s state should be reproducible from scratch, and using GUIs like ssh or cockpit can lead to mistakes. The only reason to directly work on a server is for exploratory purposes, and in that case, the choice between GUI and command line is not clear-cut. GUIs provide discoverability and visibility, which can be advantageous when setting something up experimentally.

The article highlights a passage by P.K. Dick discussing the heroic trait of ordinary people who instinctively know what they should not do and refuse to do it, even if it brings negative consequences. These individuals are not concerned with recognition or performing great heroic deeds, but rather in their quiet refusals to be compelled to be what they are not. The author relates this idea to their selective abstinence from certain areas of technological life, finding happiness in following their own path and using tools that work for them. They also speculate that the authentic human poses a threat to the overarching technological system as it cannot coexist with it.

6. Canada ends official time signal
Total comment counts : 20
Summary
The National Research Council Time Signal, which has been broadcast by the Canadian Broadcasting Corporation (CBC) since 1939, was turned off on October 9th. The time signal, consisting of a series of “beeps” followed by a signal to indicate the top of the hour, was used in the past to synchronize clocks and watches. However, with the rise of modern technology and the availability of other time sources, its main use had become as a nostalgic reminder. The decision to turn off the time signal without prior announcement has received a predictable public response, with many questioning the reasoning behind the move.

7. Better HTTP server routing in Go 1.22
Total comment counts : 23
Summary
The upcoming release of Go 1.22 is expected to enhance the pattern-matching capabilities of the default HTTP serving multiplexer in the net/http package. Currently, the multiplexer offers basic path matching, but the new version will bridge the gap from third-party packages by providing advanced matching. The article provides an introduction to the new multiplexer and compares it to the gorilla/mux package. The new multiplexer is straightforward to use if you are familiar with third-party mux/router packages. The article includes usage examples and highlights new features such as pattern matching and wildcard assignment. Additionally, the article discusses potential conflicts and precedence rules for pattern matching. It also mentions that the enhanced mux will likely shift the preference of beginner Go programmers towards using the standard library instead of third-party packages. However, some may still opt for more capable packages like gorilla/mux or lightweight frameworks like Gin. Overall, the article views the enhancement as positive for the Go community.

This article discusses the technique used in garbage collected, multi-threaded virtual machines to signal threads to stop for garbage collection. In order to avoid allocating memory while the garbage collector runs, the runtime inserts dummy instructions called safepoints at the top of loops or function entry points. These instructions write to a page that the runtime controls. When it’s time to stop all threads for garbage collection, the page is write protected. This causes each thread to eventually encounter a segmentation fault, signaling them to stop. Once all threads have stopped, the garbage collector can run smoothly. The write protection is then removed and the threads resume execution.

This article discusses the origin and purpose of signals in Unix. The writers of Unix needed a mechanism for communication between the kernel and user mode code. Signals can be understood as interrupts for user mode instead of kernel mode. Different signals map to specific events, such as processor exceptions, I/O device interrupts, timer interrupts, and platform interrupts. Signals act as a one-shot downcall mechanism that can occur at any time, requiring careful consideration of concurrency and limited access to certain parts of the system. The author even mentions porting a real-time operating system to run on Unix user mode using signals as an interrupt controller abstraction.
