glibc 堆內存管理：原理、機制與實戰
在內存管理領域，glibc（GNU C Library）通過 brk 和 mmap 兩大系統調用，構建了一套高效的堆內存管理機制。這種設計大幅減少了系統調用的頻次，顯著提升內存利用率。在 glibc 的管理架構中，堆內存以層級化的方式組織，包含分配區（Arena）、堆（Heap）和內存塊（Chunk）。其中，主 Arena 依賴 brk 系統調用實現內存分配，而子 Arena 則通過 mmap 完 ⌘ Read more

One of the nicest things about Go is the language itself, comparing Go to other popular languages in terms of the complexity to learn to be proficient in:

• Go: 25 keywords (Stack Overflow); CSP-style concurrency (goroutines & channels)
  
• Python 2: 30 keywords (TutorialsPoint); GIL-bound threads & multiprocessing (Wikipedia)
  
• Python 3: 35 keywords (Initial Commit); GIL-bound threads, asyncio & multiprocessing (Wikipedia, DEV Community)
  
• Java: 50 keywords (Stack Overflow); threads + java.util.concurrent (Wikipedia)
  
• C++: 82 keywords (Stack Overflow); std::thread, atomics & futures (en.cppreference.com)
  
• JavaScript: 38 keywords (Stack Overflow); single-threaded event loop & async/await, Web Workers (Wikipedia)
  
• Ruby: 42 keywords (Stack Overflow); GIL-bound threads (MRI), fibers & processes (Wikipedia)
  

@bender@twtxt.net Here’s a short-list:

• Simple, minimal syntax—master the core in hours, not months.
  
• CSP-style concurrency (goroutines & channels)—safe, scalable parallelism.
  
• Blazing-fast compiler & single-binary deploys—zero runtime dependencies.
  
• Rich stdlib & built-in tooling (gofmt, go test, modules).
  
• No heavy frameworks or hidden magic—unlike Java/C++/Python overhead.

PEP 793: PyModExport: A new entry point for C extension modules

@kat@yarn.girlonthemoon.xyz You don’t need to change the directory first in line 11, you can just create the directory, that’s sufficient since you’re having an absolute path.

The echo in line 13 is useless, you can simplify this to: newdir="$WD/$now" If you reversed this line with the previous one, you could make use of the variable in the directory creation: mkdir "$newdir".

In line 16, pull the directory change out of the loop upfront. The loop body doesn’t modify the working directory, so no need to reset it with each cycle. In fact, you could even spare the cd altogether when you simply tell find where to look: find "$basedir" -type f….

I didn’t try it, but if I read the manpage correctly, you should be able to simplify line 19 as well:

-C Change to DIR before performing any operations. This option is order-sensitive, i.e. it affects all options that follow.

Hence, remove the cd and put the -C "$WD" as the first argument to tar. Again, I didn’t try it. Proceed with caution.

Finally, you don’t need to specify the full path to rm in line 21. I bet, /bin is in your PATH. When you removed the previous cd from my last suggestion, the relative path that follows won’t work anymore. So, just use the absolute path that you already have in a variable: rm -rf "$newdir"

I hope you find this tiny review a wee bit useful. :-)

I came across an unfortunately dead salamander on the forest road, some fenced in deer, heaps of sheep, some unmagnetic cows (some were aligned very roughly north-south, but mainly with the axis of the best view I believe), a maybeetle and finally an awesome sunset. Not too shabby! The sheep were mehing all the time, that was really lovely to hear. And the crickets were already active, too. Didn’t expect them to hear yet.

Interestingly, you can abuse the scoring system (not manually, only with a script). Since the mouse jumps to the locations along the circle, you can just use very few steps and still get a great score because every step you make is very accurate – but the result looks funny:

Mt. Stuifen is 757 meters above sea level, has a small shelter and a barbie area and is still the most boring one of the three. It’s also the one farthest away from me.

We bought our tucker at a local bakery on our way. This was the first time I tried a Teufelsbrezel (lit. devil’s pretzel), a lye pretzel with pepper. Haven’t come across that anywhere else. But I can certainly recommend that, it’s yummy.

@lyse@lyse.isobeef.org I walked under 25°C during my lunch hour today, but with a sunshine that could fry an egg if dropped on the asphalt. I told a friend in Manila about it, and she told me that 25°C is Winter/Christmas temperatures for them. I felt cooler right away. :-)

We had some nice 22°C today. But after work, it got rather windy and cloudy, temps rapidly dropped so just 14°C. Still a nice stroll to our backyard mountain. https://lyse.isobeef.org/waldspaziergang-2025-04-16/

Quelques jours de vacances
Voilà, c’est dit : les prochains jours ne verront aucun billet paraître dans ces colonnes. Je serai en vacances. Je sais que, pour certains lecteurs, ce sevrage sera à la fois cruel et brutal.

@anth@a.9srv.net Hahaha, for a second I thought that you implemented word splitting according to Swiss (.ch) rules. :-D

Btw, both manpage links string(2) and getields(2) (it’s missing an f) point into nothingness: http://a.9srv.net/src/wordwrap.2.html

I can’t help but notice line 9: http://a.9srv.net/src/wordwrap.c

Malcolm: 6 usability improvements in GCC 15
Over on the Red Hat Developer site, David Malcolm has an article\
about improvements in GCC 15, specifically focusing on the diagnostic
information that the compiler emits. This includes ASCII art with a “⚠️”
warning emoji to display the execution path when it detects a problem (like
an infinite loop in one of his examples), better C++ template errors,
machine-readable diagnostics using [Static\

@lyse@lyse.isobeef.org that’s such a beautiful shot! If I were you I would use the full “original” one; it will do better justice to the shots. Oh, and I gladly take your 15°C! 😍

Hit by the arvo sun rays behind the window I was convinced that it is t-shirt weather. Deep blue sky, yeah, for sure! It turned out to be just 15°C and declining, though. So, I had to wear my jacket on today’s windy stroll. Pretty nice. Didn’t take many photos, but there you go: https://lyse.isobeef.org/waldspaziergang-2025-04-10/

Go 語言新版的迭代器是怎麼個事
很多流行的編程語言中都以某種方式提供迭代器，其中包括 C++、Java、Javascript、Python 和 Rust。Go 語言現在也加入了迭代器。iter 包是 Go 1.23 新增的標準庫，提供了迭代器的基本定義和相關操作。爲什麼需要迭代器——–在 Go 1.18 引入泛型之後，便可以很方便的定義一些泛型容器類型來提升編碼效率。例如我們可以基於 map 類型定義了一個集合類型—— ⌘ Read more
