------
A high performance, just in time compiled dynamic language, which gives python like productivity with C/C++ style performance. We will get into the details of why this seemingly impossible task was made possible through clever language design. Then we will geek out by generating LLVM byte code and x86 assembly code for individual functions interactively at the command line, explore meta programming with Julia's LISP style macros and learn about Julia's powerful multiple dispatch mechanism and how it differs from function overloading.
Julia is an upcoming language being embraced by the scientific and high performance computing community, running projects like Celeste on 650 000 cores processing 178 terabytes of astronomical data.

Thank God I found this video, it should have more likes. As someone with some C++/Python/OCaml/etc. background I wanted to have a good idea about the language and the whys. I have found plenty of 6-10 minute videos with more likes that basically sum up to "Julia new, clever people, C ugly, Julia nice and fast, here is the syntax". Which was mostly a hype (a believable one, but still). This video actually provided a deep enough understanding. So thank you a lot! 1.5 hours ( /1.25) well spent. There is of course a lot to learn, but this provided a very nice frame for everything. 1-based indexing will be weird though... 😀

Thanks, I thought a lot about how to try to present this as I kept seeing so many misconceptions about Julia performance from questions people asked. So many thing it is because of LLVM or type annotations, so I thought a lot about how do you really home in on the correct idea from the get-go. I definitely wanted to reach more people like you, who know a fair amount of programming but who aren't easily sold by some vague claims.

Great presentation! Despite been already converted to Julia, I still learned quite a bit from this exposition. Thank you! Looking forward to further Julia-centric talks.

[@ACCUConf]

Glad you enjoyed it!

Well done! You're delivering a talk from-home, online and the audio doesn't sound like you're using a compression algorithm from 1987.
I love your Lego nuclear reactor!

Nice video Erik! LOOOVE Julia!

[@finan2004]

Great presentation, very clear with beautiful explanations - Hope to see more talks from Erik

[@aaronkaw4857]

This is now the video I will refer my friends to to introduce them to Julia. Great structure, well planned, great examples. I just have to say, the persistent and frequent throat-clearing was a very, very distracting thorn. Other than that, thank you so much!

[@PatrickChampion]

agree on all points. I think the throat clearing, lip smacking, and other sounds are actually a tick. I use to work with someone who did this without being aware of it. It was hard to get past and stay focused then just like it was here. I find the best way is to take a break and watch in 10 minute increments if it overwhelms you. I see I will likely need to get a good book. The language has a lot of interesting and sometimes unexpected syntactic choices. A lot to ponder.

Amazing talk with well selected insights! Thank you, Erik

[@timlavers8010]

Very interesting and well-prepared talk. Thanks!

[@ACCUConf]

Glad you enjoyed it!

[@EcksteinNorman]

Thanks for this excellent talk !

[@ACCUConf]

Glad you liked it!

hello my name is Julia... I'm a programmer. Maybe I should learn julia!
