I'll describe some of the more fundamental issues in Julia today, as I see it, and how we can potentially solve them to get a better language.

00:00 Welcome!
00:50 Purpose of the talk
02:04 Users should speak about their problems with Julia
02:34 Widely know bad things about Julia
06:54 Is the presented list of problems exhaustive?
07:30 Why some problems were chosen as the main topics of this talk
07:53 Modularity
09:14 Example of modules we want to keep separate
12:03 Problem with isolating constructors
13:01 Types
14:06 How to handle Missing type in code

16:25 Opaque method specificity rules
17:40 First, the most important rule of method specification
18:09 Second "rule" of method specification
18:45 Why we have a problem with second "rule"
21:34 Problem of "X is more specific that Y. Example 1
23:32 Problem of "X is more specific that Y. Example 2
25:20 Conclusions
26:15 Q&A: What would happens in the case of circular specification?
27:09 Q&A: What would happens if specification rules were stricter?
27:52 Q&A: How many methods need to be write to allow to make specifications rules stricter? (Follow up to previous question.)
28:18 Q&A: What is the order of priority of fixing well know bad things in Julia?

A programming language to heal the planet together: Julia  | Alan Edelman | TEDxMIT
John Baker
16 Views · 2 years ago

Even as the climate is warming, there is so little we know about it today. Computational modeling is how climate scientists reconcile our understanding of climate with what we observe. Traditionally, these models would have been written in Fortran, but today’s climate emergency needs tools that are significantly easier to work with. Julia was built for this purpose and makes it easy for everybody focused on solving the problem to work together effectively. No more silos; we must now be part of an interconnected world.

David Higgins - Introduction to Julia for Python Developers
John Baker
16 Views · 2 years ago

PyData Berlin 2016

Julia is a performance oriented language written from the ground-up to support numerical processing and parallelisation. The basic syntax of Julia resembles a cross between Matlab and Python, but offers performance which is comparable to compiled C-code. I will present an overview of the language with particular emphasis on where Python users may benefit in using it in their daily work.

Python users have long benefitted from the less verbose nature of Python, when compared with C and Fortran. However, Python was originally designed for scripting tasks, using dynamic types and widescale object orientation, neither of which features are necessarily beneficial when it comes to numerical computing. Thus, we have seen the widespread use of Python libraries for numerical computation (scipy, numpy, etc.).

Julia is a new language, developed at MIT, which attempts to learn from the experience of development of Python and similar languages. The main goals are to provide a non-verbose, performance oriented language written from the ground-up to support numerical processing and parallelisation. In its most basic syntax Julia resembles a cross between Matlab and Python, but via compilation through an intermediate level representation (llvm) it offers performance which is comparable to compiled C-code.

I am not going to argue that Julia is ready for primetime yet. However, it is definitely worth consideration by anyone currently resorting to cython or needing distributed access to large datasets.

I will present an outline/introduction to the language, including the main benefits and current weaknesses. Of particular interest to the audience may be the fact that Python libraries are importable and callable from within Julia, allowing a continuity of existing workflow but from a Julia-based host environment. My main focus will be for a numerically literate audience who are already contending with the technical limitations of Python and are curious about the new language in town.
