Thinking about Concurrency, Raymond Hettinger, Python core developer

[@magniffsdigitaldevices2153]

When I grow up I want to be just as great as Raymond.

I love him but the constant struggle with the audience not giving feedback kind of ruins this. At some point you have to give up asking - the awkward silence is getting painful to watch. This doesn't mean the audience is bad, though - maybe they're not used to such interactive speakers, maybe they don't feel confident replying in english - but at some point you just gotta stop torturing them.

[@salkdjfasldkfjsdlk]

I'm guessing they raised their hands.

[@TP-kq9ul]

They did laugh at some points. And to my understanding, this happened in Russia, where they are not so good with English. And non-native English speaker tends to process listened English way slower than the native, let along saying something back.

[@kicknotes]

He's in Russia. They don't laugh there. By Russian standards, that audience thought they were at a comedy club.

[@BeatButton]

They never give this man enough time to speak.

[@zozouzid]

This guy has legendary skills in explain concepts simply, that might have otherwise unleashed a war with the brain.

[@guambejr]

Fun watching this... Makes me wanna learn more... Even use Twitter for a chance to receive his updates. Awesome

[@JohnDoe-vr4et]

I learned something new today.

I once debugged a touchscreen driver that would only detect the end of touches when the system was overloaded. It was not multithreaded.

[@andreienache6290]

The heisenbug is sooooo mid blowing hahahaha loved the idea, I had this experience....

[@reginaldcrapo132]

You are brilliant, Raymond.

[@yo-qu4hu]

Awesome Raymond!

[@armynyus9123]

single quotes, keep it up Raymond :-)

[@nishankbani3257]

Ha ha..Good fun. Great content and delivery.

[@Johnged15]

Learned a lot but got some way to go.

The version with locks should contain the queues corresponding function for printing. The given code is repeating itself three times: `with printer_lock: print`

[@CristiNeagu]

16:28 No, it didn't. The expected last 3 lines of the output are: The count is 10 ------------------------ Finishing up But what we got was: The count is 10 Finishing up ------------------------ So that print really is a problem.

[@gowthamramesh2443]

I was searching for some comment to point out this exact same thing _/\_

[@TomaszTomanek]

At the begging Raymond mention the name of framework he used for the "slides" - what was it? I can't find it somehow. Thanks!

[@Glut2Tube]

He used Sphinx, a tool for creating documentation: www.sphinx-doc.org/

[@TomaszTomanek]

Thank you!

[@mckenziejohan4149]

i wish he is my teacher

[@trejkaz]

You wish email were atomic. In reality, email messages go missing because one or more servers doesn't implement atomicity or doesn't implement it correctly. I took my hand down at the second question, because I have an email account, but not an atomic messaging queue. I use Gmail.

[@drasticfred]

#gilectomy Instead of locking whole interpreter, better of lock variables/objects, upside down isolation for threads can be achieved. Introduce a bitmap table for vars/objs mark them locked/unlocked etc. i.e encouraging local vars/objs usage only touch globals while returning. Don't mess with message passing either.

[@lbbc33]

36:18 Is removing the reference the reason why he deletes both (_print_manager_ and _counter_manager_) daemon threads? Assuming the daemon still be running after deletion.

[@jordangillard6962]

How can anyone tell Raymond he's out of time? Let the man talk for hours!

[@Neceros]

I'd like that sample code.

[@armynyus9123]

gevent ftw!

[@STIVESification]

I am using Python 3.7 Right now

[@林玮-k4c]

hahaha!!!!!!!!!!! it‘s so fun.

[@minecraftmagic3519]

[@Shockszzbyyous]

such a quality mic and such low quality audio ??

[@jimstanley_49]

Placed poorly and/or EQ not set for his voice.

[@TheRedbeardster]

Конкарренси в питоне?

[@Sousleek]

Почему нет?

[@stargazer7644]

As smart as this guy is, you'd think he'd know how to pronounce daemon.

[@varushvarsha6768]

20 minutes in, just senseless babblings about multi threading ad nauseam........ Little substance, more praising glory to the substance.
