[@0xDEAD_Inside]

@@nateF888 it means you don't have to use wierd libraries and syntax to run GPU code. Eg. Cuda

[@bastianurbach]

@@nateF888 GPUs use a variation of SIMD parallelism, which means that the same code is executed simultaneously on many different sets of data. This is great for graphics because quite often you'll need to run the same code once per pixel or once per vertex of a 3D object or something like that. It does however come with some restrictions. Even a simple if-else requires a bit of trickery and is only efficient in some cases. What GPUs simply cannot do is function pointers. You may not notice it when programming in a high level language but most languages extensively use function pointers, i.e. they pass a reference to executable code around like a value. This makes translating code for the GPU from normal programming languages challenging. Usually you use GPU-specific programming languages like GLSL or HLSL. As for why it's great to run code on the GPU: SIMD parallelism is very efficient for tasks where it works well. An Intel Core i5 12400 can perform 47 billion floating point operations per second (and I think that already includes the little bit of SIMD that even CPUs have nowadays). It also comes with a basic integrated GPU so that it can be used without an actual graphics card. It's not enough for high end gaming but it's ok for most everyday tasks. That Intel UHD Graphics 730 on the same chip can perform 350 billion floating point operations per second.

It feels so much modern, consistend, well-thought through, it was like an epiphany, while i was fighting with R on many occasions, the Julia syntax just felt right, it was like "if i would be creating a language for maths and stuff, it would be exactly like this" =)

FYI matlab is jit compiled as well, but with quite a different phylosophy wrt to julia, most probably the 20x speedup comes from memory management / allocations. I would bet numba achieves far less than 1000x wrt to matlab here (note that in general matlab is way faster then pure python).

Likely. Depends on what you mean by data visualization, for text analysis, working with tables and plotting graphs, I'd choose Python. For working with large 2D to 4D data and computing them on fly, Python is painfully slow. Still viable if you can prototype it at small resolution and run overnight. But if you are doing some data processing and Python does not have fast library written in C++ for that purpose, maybe Julia is worth trying (C++ might be an option as well)

[@Eagle3302PL]

@@leonf.7893 Honestly, the only differentiators are the core library and the frameworks. You can do any task in any language with equal effectiveness as long as you sufficiently optimize the compiler or the runtime. The thing is that languages are built by communities, so they will prioritize core features and optimizations for specific tasks which in the long term makes them excel at that specific task while everything else is sidelined. Almost every language exists because at some point someone thought "I want feature x in language y with optimizations for z" so they create a chimera that's focused on their specific problem, then people that have a similar problem congregate.

[@danielcelisgarza]

I think the language will properly explode with Julia 2.0. I think that's when they want to have full support for ahead of time compilation. So executables can be small and portable. Currently, you can statically compile your code, but the executables are huge because they include everything exported by dependancies or imported by your code.

[@jwcfive7999]

I started learning Julia a few weeks ago, and all I can say is that it is by far my favorite programming language. I will give my opinions on it, but I'm not extremely familiar with computer science, so forgive my vocabulary and lack of other languages for comparison. I will say what I like as I think of it. I love the range operator (:), it makes it very easy to iterate through values, and can also be reversed and modified to include a jump (sorry for the lack of better words). It also works with strings, as it does in python. However, it has a few differences from pythons. First of all, the range operator can actually be used in a for loop. For example, for i=1:10 ... end instead of for i in range(1,10). Another difference is the use of the end operator. In python, strings can be accessed from the last index using something like [-3:]. But in Julia, end must be used, for example as [end-3:end], which is better for visual purposes and avoiding confusion. Speaking of end, Julia avoids any confusing by closing if statements, functions, for/while loops, do statements, let statements, structs, and more using the end keyword, which avoids confusion and removes the picky indentation system that python features. semicolons are also available for use, but are optional Functions can also be declared like f(x) = x + 2, which is very cool in my opinion. I'm not aware of any specific language that does this other than Julia, but there are likely some. Another thing I love in Julia is the unicode implementation. In VSCode, I can input unicode characters that actually are interpreted as certain things. for example, for i in 1:10 is the same as for i ∈ 1:10. There are so many more examples of this, which I find very fun to use. I mentioned earlier do statements, which make iteration and other things very easy. Things like map( num -> num+2, 1:10 ) can be replaced with map(1:10) do num num+2 end, which is very syntactically nice. These are just a few of the things I enjoy, among so many more. If you like simple but powerful languages, check out Julia. I did, and I don't regret it. Programming in Julia is extremely enjoyable. It has its own package manager, great documentation, many amazing packages, so many functions and tools, and much more. Enjoy!

[@bismajoyosumarto1237]

Just wanted to let you know, functions that can be declared like f(x) = x + 2 is a feature of a programming paradigm called "functional programming". Pretty much all "functional programming languages" (programming languages that mainly follow the functional programming paradigm, such as Haskell) have that feature. You can also do that in Python using lambda as follows: f = lambda x: x + 2

If I'm not mistaken, Julia isn't JIT. The compiler isn't active during runtime. I've seen people in the Julia community calling it "Just Ahead of Time", instead of "Just in Time".

As long as you understand the basic computer science concepts you can learn many languages at once. Especially if you get the hang of C!

@@abdullahmertozdemir9437 If you don't have any particular projects in your head, I would suggest to learn C# for Windows Applications OR Kotlin for Android Applications OR Swift for anything Apple related OR JavaScript for Web. Those languages are easy to pick up and write in. After that you could learn whatever you want ;-)

[@abdullahmertozdemir9437]

@@igorthelight Currently I have C++, JavaScript and Julia in my bucketlist (gotta add Flutter there when I am done with them all for quick mobile apps) but I think I am at that phase where you get into something new and go "and I will do this and that" then realize it is just not that easy. For now I want to learn SFML and OpenGL for C++ and then will jump to javascript course on scrimba. Only then, I believe, I can start talking about learning any other thing

Because of the multiple dispatch, Julia has built-in support for solving the Expression Problem. Which is really neat!

Compilation: AoT makes sense for releases, while JiT makes sense for real time development and sciencey things. Interpreted makes sense for shells/hacking. Languages should be more ambitious in covering all the bases.

[@KennethKasajian]

I don't get why multiple-dispatch is necessary to determine which function to call in the case when the switch is based on a static type, such as string or int. The compiler knows at build time which version ought to be called and could mind to that specific version directly, not that different from overloading. Perhaps the example of multiple dispatch here is wrong. Maybe an example where the runtime type is used for dispatching, or possibly another value, such as greater than zero, or equal to zero. I don't know. Never used the language, but if it's statically typed, that design wouldn't make sense.

[@halneufmille]

You can do that by knowing in advance your function may encounter only say string or int64 in the future. But in julia, you can use somebody else's function in your code, invent some new type you need for yourself, write what this function does when it encounters your new type and use it with the whole julia ecosystem without ever modifying the initial code. To learn more, I suggest this nice talk by one of the language creators: kzbin.info/www/bejne/oZSceaqprapkhbs

[@Lennyp4]

it’s pretty common to run into situations in C++ or similar where you’ve got a dozen similar functions for a variable that could be 4 or 5 different types. C++ has templates and overloading, but it doesn’t have any runtime type checking whatsoever leading to a web of if statements and super repetitive code. i think it’s a pretty welcome feature that the language will step in and help me dispatch the appropriate function if i want

[@lorenzomonacelli]

The major advantace of multiple dispatch is that you can dispatch functions of libraries you are importing, chainging the internal behaviour of a library without touching the original code. This is what makes it so powerful: you can implement your objects, define basic operations on them, and call any julia library passing them as a argunent and it works! There are amazing interactions between packages in julia thanks to this feature.

"Unlike most high level languages it uses a just-in-time compiler" => "like most high level languages that aren't Python..."

[@xerotolerant]

What's the difference between dispatching and function overloading?

[@jvillemare]

I looked it up. I can't link the software engineering stack overflow post here w/o being reported as spam, so I'll summarize: dispatching is for dynamic types (types that can change at runtime). Overloading is only for static types (so like Java). this seems like a weird difference to have a whole new confusing term for.

[@xerotolerant]

​@@jvillemare Ah. Thank you. At least there is a difference. And now we know it's safe to think of them as essentially the same.

[@davidf760]

It's not the same, in Java for example yes you can have multiple functions with the same name but different argument types (overloading), but when you invoke such function you explicitly need to say which one you want to use, you can't simple pass generic types, the code will not compile. With multiple dispatch, like in Julia, you don't need to specify, you just pass an object and in runtime the correct function is selected (this is multiple dispatch, which Java doesn't support) .
