systemd is, to put it mildly, controversial. As a FreeBSD developer I decided I wanted to know why.
I delved into the history of bootstrap systems, and even the history of UNIX and other contemporary operating systems, to try and work out why something like systemd was seem as necessary, if not desirable. I also tried to work out why so many people found it so upsetting, annoying, or otherwise rage-inducing.
Join me on a journey through the bootstrap process, the history of init, the reasons why change can be scary, and the discovery of a part of your OS you may not even know existed.
linux.conf.au is a conference about the Linux operating system, and all aspects of the thriving ecosystem of Free and Open Source Software that has grown up around it. Run since 1999, in a different Australian or New Zealand city each year, by a team of local volunteers, LCA invites more than 500 people to learn from the people who shape the future of Open Source. For more information on the conference see linux.conf.au/
Frederik Imbo studied theatre at the Royal Conservatory of Ghent and has acted in lots of television series. He founded Imboorling and now has over 15 years experience in stimulating and supporting people. With the aim of improving their communication skills Frederik gives presentations, workshops, training courses and personal coaching sessions to anyone prepared to make their two ears available.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx
Important error correction: In the video, I say that Dirichlet showed that the primes are equally distributed among allowable residue classes, but this is not historically accurate. (By «allowable», here, I mean a residue class whose elements are coprime to the modulus, as described in the video). What he actually showed is that the sum of the reciprocals of all primes in a given allowable residue class diverges, which proves that there are infinitely many primes in such a sequence.
Dirichlet observed this equal distribution numerically and noted this in his paper, but it wasnt until decades later that this fact was properly proved, as it required building on some of the work of Riemann in his famous 1859 paper. If Im not mistaken, I think it wasnt until Vallée Poussin in (1899), with a version of the prime number theorem for residue classes like this, but I could be wrong there.
In many ways, this was a very silly error for me to have let through. It is true that this result was proven with heavy use of complex analysis, and in fact, its in a complex analysis lecture that I remember first learning about it. But of course, this would have to have happened after Dirichlet because it would have to have happened after Riemann!
My apologies for the mistake. If you notice factual errors in videos that are not already mentioned in the videos description or pinned comment, dont hesitate to let me know.
— These animations are largely made using manim, a scrappy open-source python library: github.com/3b1b/manim
If you want to check it out, I feel compelled to warn you that its not the most well-documented tool, and it has many other quirks you might expect in a library someone wrote with only their own use in mind.
If you want to contribute translated subtitles or to help review those that have already been made by others and need approval, you can click the gear icon in the video and go to subtitles/cc, then «add subtitles/cc». I really appreciate those who do this, as it helps make the lessons accessible to more people.

Здравствуйте, друзья! Не так давно у меня появился этот замечательный домашний компьютер Commodore 64, и вот, у меня нашлось время на то, чтобы разобрать его, привести в порядок и скрафтить для него несколько периферийных устройств. Конечно же, с запуском и тестом этого изделия. Приятного просмотра!
It is the first TEDx talk of the founder of Free Software movement. Stallman, RMS for short, has changed the world with his vision of freedom for the digital age. He launched the GNU operating system, used with Linux as a component, and inspired the development of Creative Commons licences and Wikipedia project. In this talk, Stallman describes how nonfree programs give companies control of their users and what users can do in order to recover control over their computing.

Показываю как установить Windows 10 на ваш компьютер с полным объяснением всех этапов установки: создание загрузочной флешки с драйверами и набором программ, настройка БИОСа, установка Windows, установка драйверов и набора программ, настройка Windows после установки как это делаю я. Во всем этом расскажу вам несколько интересных секретов )

С помощью видео вы сможете легко прокачать ваш компьютер, установить Windows. Удалить все вирусы и гадости из Windows. Выявить майнеров и другие угрозы. Провести самостоятельную диагностику своего компьютера.
Одним из бесспорных преимуществ Linux перед другими операционными системами является богатое разнообразие рабочих столов (графических оболочек) под любой вкус и цвет, а также под любые совершенно технические характеристики компьютера. Если в Windows у вас практически нет выбора, у вас только один рабочий стол (да и в MacOSX так же), то в Linux вы можете установить целый букет самых различных графических окружений и работать в любом, какой больше нравится.
Здесь мы рассмотрим установку наиболее популярных графических оболочек для Linux: Gnome Shell, Gnome Flashback, Cinnamon, KDE, XFCE, LXDE и e17
На ремонте сегодня плата ASUS N56VM, которая недавно уже была на канале. Но здесь все гораздо интереснее. Ноутбук пытается включиться и тут же отключается, но с n-го раза может все таки заработать… Результаты диагностики оказались очень неожиданными…
Здорова! В этом видео я показываю каким образом можно писать свои скрипты в роблоксе. Я показал несколько команд для Roblox Studia, с помощью которых можно писать скрипты и создавать свои игры. Так-что это даже видео типа как создать свою игру в роблоксе
Приятного просмотра
