Ранее я делал серию постов про битовые операторы. Вот вам ещё один наглядный пример как это используется в Python в модуле re. Чтобы указать флаг для компилятора нам надо указать его после передаваемой строки. Например, добавляем флаг для игнорирования переноса строки. pattern = re.compile(r"(\w+)+") words = pattern.search(text, re.DOTALL) А как указать несколько флагов? Ведь явно будут ситуации когда нам потребуется больше одного. Кто читал посты по битовые операторы уже понял как. pattern.search(text, re.DOTALL | re.VERBOSE) А теперь смотрим исходники, что находится в этих атрибутах? Не удивительно, степени двойки. Почему? Потому что каждое следующее значение это сдвиг единицы влево. >>> for n in [1, 2, 4, 8, 16, 32, 64, 128, 256]: >>> print(bin(n)) 0b1 0b10 0b100 0b1000 0b10000 0b100000 0b1000000 0b10000000 0b100000000 Чтобы было понятней, давайте напишем тоже самое но иначе, добавим ведущие нули: 000000001 000000010 000000100 000001000 000010000 000100000 001000000 010000000 100000000 Не понятно что тут происходит? Читай три поста про битовые операторы начиная с этого ➡️https://t.me/pythonotes/45 В общем, это пример применения побитовых операций в самом Python. Теперь вы знаете Python еще немного лучше) #tricks#regex#libs

Jitsi's official instance now requires you to authenticate with Facebook, Google, or Microsoft to host a call https://jitsi.org/blog/authentication-on-meet-jit-si/ Jitsi was a quick-and-easy (not to mention private and anonymous) video chat tool for friends and also strangers. Jitsi's killer feature was being a FOSS 1-click, no sign-up call service. Now you'll have to deploy your own instance if you want to avoid authenticating with Facebook, Google, or Microsoft (Github). But by deploying your own instance, you are effectively no longer anonymous, as you'll need to provide billing info to your host, or provide your home IP so folks can connect to it. https://jitsi.github.io/handbook/docs/community/community-instances/ This list is dynamically refreshed and provides a fair amount of alternative servers: https://ladatano.partidopirata.com.ar/jitsimeter/ #jitsi#videocall

#TBOT Show 7: The Significance of Dorsey’s Bitchat, Worlds First eSIM Hack, Mexico’s Digital ID, New Show Source Insights Took a week off and now I’m back. 😎 (with a new addition to the show?!) (also - big sorry for the show being 40 minutes) WATCH THE SHOW ON SUBSTACK https://odysee.com/@takebackourtech:f/tbot-show-7:6 Here’s the stories for the week: Jack #Dorsey’s #Bitchat - The Real Story: The tech mogul Jack Dorsey released a censorship proof messaging app in late June - named Bitchat. It runs a #bluetooth#mesh network, end to end #e2e#encryption, and rolling IDs and is picking up traction. I share my thoughts on the app, and concerns I have - but that’s not even the real story. I think Jack has a bigger message than just the app. World’s First #eSIM Hack: A security lab out of Poland just demonstrated a hack on one of the largest SIM providers for IoT devices. We’ll get techy in our understanding and ask the question, could this impact our phones? #DigitalID, Coming Soon To #Mexico: The Mexican government has signed a new #Biometric#ID law, known as the CURP. How is this enforced and what does it mean for Mexican residents? Find out today. Decentralized #Video Conferencing: Recently I’ve been relying more on video conferences instead of calling people, especially while traveling. Good thing I’ve got the #Jitsi app, I’ll show you my setup! #videocall New Show, “Source Insights”: You follow #TBOT to stay informed on tech freedom. Now go deeper with a new weekly show “Source Insights”, where Hakeem shares his tools, lifestyle and productivity tips, entrepreneurial advice, wisdom from guides, and personal experiences.
