Чуть подправил скрипт , чтобы лишний раз не бегал по клиентским пирам, которые подключаются к этому роутеру, а только где роутер как клиент.
Работает убойно! Proton и Warp пробивает)

Upd.: увеличил время в фильтре до 2м30с как защита от ложных срабатываний у медленных подключений.
Считаю выполнение скрипта раз в 2 минуты средним нормальным значением.

How to keep using adblockers on chrome and chromium

NOTE

by the time you're reading this, this probably no longer works since the policy has been removed. I reccomend you to check out https://github.com/r58Playz/uBlock-mv3 instead

How to keep using adblockers on chrome and chromium

  1. google's manifest v3 has no analouge to the webRequestBlocking API, which is neccesary for (effective) adblockers to work
  2. starting in chrome version 127, the transition to mv3 will start cutting off the use of mv2 extensions alltogether
  3. this will inevitably piss of enterprises when their extensions don't work, so the ExtensionManifestV2Availability key was added and will presumably stay forever after enterprises complain enough

You can use this as a regular user, which will let you keep your mv2 extensions even after they're supposed to stop working

WireGuard DPI обход РКН - Windows

Для обхода блокировки достаточно отправить 1 любой udp пакет, тем самым нарушим начальное определение протокола WireGuard
Способ с использованием Windows PowerShell. Без скачивания Nmap и подобного софта.

Шаг 0: Отключитесь от всех туннелей.

Шаг 1: Редактируем Клиент конфиг

Добавим в него "ListenPort", это позволит иметь статичный порт на котором будет работать WireGuard
Нажмите ПКМ на нужный "туннель" и выберите "Редактировать выбранный туннель..." Step1

После DNS добавляем новую строку

A small state-of-the-art study on custom engines

CUSTOM GAME ENGINES: A Small Study

a_plague_tale

WARNING: Article moved to separate repo to allow users contributions: https://github.com/raysan5/custom_game_engines

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like [Unreal](https:

PCI-e bus bandwidth calculation

How PCI-e bandwidth and actual true data bandwidth can be calculated.

PCI-e 1.x uses an 8/10b encoding scheme, so to send 8 bits of data, 10 bits of encoded data must be transfered. 2 of those bits are there as error checking and correction bits to account for interference which is very common on fast buses. SATA btw also uses 8b/10b encoding, you loose 20% of bandwidth (1-8/10) to get the data across.

PCI-e 1.0 is clocked at 2.5Ghz, it sends 1 bit per clock cycle and each lane corresponds to a 1 bit bi-directional serial channel. Which is kind of neat since here 'Gigatransfers' indicate 1 bit transfered for every clock cycle. This should immediately tell us that unlike FSB which transfers multiple bts per cycle in a parallel fashion, PCI-e is serial, since we are sequentially throwing 1 bit of data per cycle onto the bus and it takes multiple cycles to send a full byte. While on a parallel bus multiple bytes can be sent per cycle.
