How to Enable Wi-Fi on MacBook, Mac Mini, MacBook Air for Ubuntu/Linux OS

By default older Mac computer models have driver issues with the Broadcom Wi-Fi chip. Most instructions online (such as this one from the official Ubuntu docs @ https://help.ubuntu.com/community/Macmini5-1/Precise) suggest to use sudo apt-get and install these packages from the PPA.

BUT you don't have Internet so you can't use apt-get! Instead you can use a different computer to download the packages, then transfer them over.

In the instructions below, you will need to replace sid in the download URL's with the proper version of Debian your version of Ubuntu/Linux is using. To find which version you should use, you can view the chart at https://askubuntu.com/questions/445487/what-debian-version-are-the-different-ubuntu-versions-based-on#445496. If you're using jessie for example, then replace all sid with jessie in the links below.

What's new in Swift 6 (Swiftify article translated into Russian)

Что нового в Swift 6 (перевод статьи Swiftify)

Apple планирует выпустить Swift 6 в сентябре 2024 года наряду с Xcode 16. Это будет первое крупное обновление Swift за последние пять лет, начиная с Swift 5. Этот выпуск приурочен к 10-летнему юбилею Swift. За эти годы Swift значительно развился, от простого улучшения Objective-C до безопасного, многофункционального и производительного языка, который легко использовать.

Apple ранее упоминала, что будут последовательно выпускаться версии Swift 5.x, вводящие инкрементальные изменения и новые функции для подготовки к Swift 6. Основные цели включали улучшение поддержки параллелизма и модели владения памятью. На данный момент они были достигнуты в значительной степени.

Давайте кратко вспомним эволюцию версий Swift

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse
