Fortran, a matrix native/primitive language outperforms CUDA on GPU matrix computations.
The reason is very simple. It is all about the unnecessary bottlenecks introduced by the concept of a von Neumann machine and the C pointer logic that are fatal to concurrent computation of a massive amount of structured data running only a couple of identical operations.

My thieving tendencies come down to this: if I see something just lying around, I can't resist the urge to take it. This has netted me numerous children's toys from the town park, flip-flops at the beach, and backpacks & cellphones left at cafe tables. It's not the value or utility of the object, it's the availability. /Here I am! Come take me!/
Today I picked up a laser #pointer from a lectern & a set of blueprints from a university building under renovation. Score!

Can we turn a file tree structure into a matrix? Everything in a computer can be represented by an #array or a #matrix or a #tensor.
aaa.bbb.ccc.x.txt
ddd.y.txt -> ddd.""."".y.txtaaa bbb ccc x.txt
ddd "" "" y.txtWe are no longer shackled by the naive von Neumann machine that has only 1 or a few cores or threads. We can layer down millions of data points and apply one instruction on them all at once. There is no more pointer tree chasing. The #C #pointer logic virus subsides.

Nu bij Pointer:
De zorg in vrouwengevangenissen is abominabel geregeld. Jonge vrouw ging lopend de gevangenis in en kwam er in een rolstoel weer uit. Al haar lopende afspraken werden stopgezet.
Ook bij medicatie worden ernstige fouten gemaakt.
Eerder verscheen hier al een kritisch rapport over van de Klara Wigman Stichting:
"Zorg voor gevangenen is voor de Tweede Kamer niet sexy."

Память в JavaScript: Stack и Heap
Последние пару лет изменили то, как пишется код. Copilot, Cursor, ChatGPT, Claude - все это генерирует вполне работающий JavaScript быстрее, чем успеваешь сформулировать задачу. Это удобно. Но у этого удобства есть обратная сторона, сгенерированный код работает правильно в смысле делает что просили , но не всегда правильно в смысле не течет по памяти и не роняет прод под нагрузкой . Модели хорошо знают синтаксис и паттерны. Они значительно хуже разбираются в том, что происходит под капотом конкретного движка. Closure, захватывающий лишние данные. Event listener, который никогда не снимается. Объект, который непреднамеренно продлевает жизнь половине DOM дерева. Все это - настоящие ошибки, которые реально встречаются в проде и ни один линтер их не поймает. Чтобы замечать такие вещи при ревью, нужно понимать, как именно V8 хранит объекты и когда решает их удалить. Это не академическое знание - это инструмент, который меняет то, на что смотришь в коде. Эта серия состоит из трех частей. Первая - про то, как V8 вообще организует память, что такое Stack и Heap, чем они отличаются и что такое pointer. Вторая - про сборщик мусора, как он определяет, что живо, а что нет и как делает это, не останавливая программу надолго. Третья - практическое применение, откуда берутся утечки памяти, как их искать и как писать код, который не создает лишней работы для GC. Смотреть под капот

Mouse improvements in Terminaux 8.1
Since Terminaux 4.0, mouse support was added to make C# console applications more interactive. This was done by abstracting the implementations of both the Windows API for detecting mouse clicks in the terminal using the combination of PeekConsoleInput() and MOUSE_INPUT_RECORD, and the Linux method for mouse clicks using the SGR/X10 VT sequences that we have to parse ourselves. The end result is a single function that handles mouse and keyboard input on a ReadPointerOrKey() function, further branched to a non-blocking version.
As a result, we’ve integrated mouse support to all kinds of interactive user interfaces within Terminaux, which resulted in both the library and Nitrocid handling all mouse input, as well as Terminaux programs having mouse support built-in without re-implementing support. However, there was room for improvements when it comes to the selection-based user interfaces.
Terminaux 8.1, which will be released two weeks from now, will feature improvements to mouse support when it comes to the choice selection style TUIs, as well as the interactive selector TUIs. Starting from this version:
- In the selector TUI, double-clicking on an item in either the first pane or the second pane will trigger the “submit” action, which, by default, is defined to an action bound to the Enter key. For example, in Nitrocid 0.2.0, if you double-click on an SMultivar settings entry in the second pane, the child settings entries underneath this entry will be revealed.
- In both the selection style and the infobox selection input TUIs, double-clicking on an item in the list of choices will confirm the selection. This allows you to confirm your selection without accidentally selecting a wrong item, since those TUIs always show a list of choices.
This is a behavioral change to the three affected Terminaux input components, which will land to Nitrocid 0.2.0 and 0.1.0 Service Pack 6 next month.

De politie zegt altijd dat het geweld met de jaarwisseling ongekend is. Dan moeten nieuwsmedia zelf uitzoeken of het erger of minder erg is dan de afgelopen jaren. In mijn beleving was het 40 jaar geleden (met veel gewonden en soms doden bij de kerstbomen jacht) veel erger maar dat hoor ik nergens. #1vandaag #pointer
