Programming Python

'Mojo May Be the Biggest Programming Language Advance In Decades' (www.fast.ai) 126

Mojo is a new programming language developed by Modular1 that aims to address the performance and deployment limitations of Python in areas like AI model development. After demoing Mojo prior to its launch, Jeremy Howard from the non-profit research group fast.ai said it feels like coding will never be the same again. Here's an excerpt from Howard's article: Modular is a fairly small startup that's only a year old, and only one part of the company is working on the Mojo language. Mojo development was only started recently. It's a small team, working for a short time, so how have they done so much? The key is that Mojo builds on some really powerful foundations. Very few software projects I've seen spend enough time building the right foundations, and tend to accrue as a result mounds of technical debt. Over time, it becomes harder and harder to add features and fix bugs. In a well designed system, however, every feature is easier to add than the last one, is faster, and has fewer bugs, because the foundations each feature builds upon are getting better and better. Mojo is a well designed system.

At its core is MLIR (Multi-Level Intermediate Representation), which has already been developed for many years, initially kicked off by Chris Lattner at Google. He had recognized what the core foundations for an "AI era programming language" would need, and focused on building them. MLIR was a key piece. Just as LLVM made it dramatically easier for powerful new programming languages to be developed over the last decade (such as Rust, Julia, and Swift, which are all based on LLVM), MLIR provides an even more powerful core to languages that are built on it. Another key enabler of Mojo's rapid development is the decision to use Python as the syntax. Developing and iterating on syntax is one of the most error-prone, complex, and controversial parts of the development of a language. By simply outsourcing that to an existing language (which also happens to be the most widely used language today) that whole piece disappears! The relatively small number of new bits of syntax needed on top of Python then largely fit quite naturally, since the base is already in place.

The next step was to create a minimal Pythonic way to call MLIR directly. That wasn't a big job at all, but it was all that was needed to then create all of Mojo on top of that -- and work directly in Mojo for everything else. That meant that the Mojo devs were able to "dog-food" Mojo when writing Mojo, nearly from the very start. Any time they found something didn't quite work great as they developed Mojo, they could add a needed feature to Mojo itself to make it easier for them to develop the next bit of Mojo!
You can give Mojo a try here.

        No. As it says right in the article, it uses a new intermediate and most of the work was building a compiler for that. What it does *not* say in the summary is that the intermediate in question is designe to run AI-like massive threading tasks, as opposed to finely tune smaller application-like code that LLVM specializes in.

    If you read the full article, it's essentially just a solution to Python having poor performance.

    I mean, okay, but being able to write in a high level language yet have the performance of a low level one has been the pipe dream of language development for decades now. Ultimately, unless there is some step change in computing power, you just can't abstract away the underlying von neumann architecture and then get a big shock when that architecture chokes on some high level code sequence that hammers dynamic memory or pipelines etc.

    In many respects, the reasons why Python is so successful now is that we have very powerful machines compared to most of the tasks it is used for. In the 1980s a language like Python would have required very careful use to avoid a single overly ambitious line destroying performance or consuming all the memory. Programmers had to understand the hardware to do most useful things.

    Today, AI is at the bleeding edge of hardware capabilities, so really you just need to have someone who has a bit of an idea of how the hardware is working. Trying to 'solve' this problem of ignorance with fancy solutions is unlikely to work that well, and ultimately, I just don't understand why it's so hard for someone to learn the basics of CPU/GPU architecture. If you're doing serious AI research this should not be beyond you - it's pretty simple stuff.

    I see the same ignorance in a lot of Javascript. It is possible to absolutely destroy a modern CPU doing something very simple if you just ignore the underlying hardware, while on the other hand you can write code that runs quite well by being a little respectful. Unfortunately, a quick perusal of most webpages suggests that ignorance is bliss for most developers.

      Of course, this is not a problem technology can solve. You either understand the hardware and code for it, or you do not and lose performance. There really is no way around that until we get AGI. If we ever get it and if it then wants to work for us in the first place.

      • Nobody is designing complex modern applications in pure C. You're either using frameworks by coding in a language that provides them or you're building your own inner platform from scratch every time you start a new project. Layers of abstraction are necessary to prevent you spending all day inventing the wheel.

          Python is very nice glue code and very nice for not performance critical stuff. For any heavy lifting, it is just not the tool to use. But embedding C is easy (Have done if for the high-performance parts of a simulator) and as a glue, Python gives you excellent flexibility and still somewhat reasonable performance. I agree that Perl is easier for a lot of simple things, but have you ever tried to embed C in Perl? It can be done, but I gave up on it pretty fast.

          • One selling point for Mojo is it is easier to debug the system if you don't have to cross between worlds. Their argument is you can still use an existing performance critical C library for one task but you can develop a new performance critical library in Mojo for another task and the latter would be superior in terms of software maintenance. I kinda buy that.

        Whether one *should* do the code at a lower level is a problem dependent variable, and technology can definitely address where on the curve that answer.

        C is essentially useless for the tasks this system is aimed at. While one can, of course, write the same code in C, doing so would require an enormous amount of said code and perform about the same speed. So lots of work for little benefit.

          The reason that so much AI is built in Python has absolutely nothing to do with technical details at all. The reason Python is used in AI is because there are so few actual ML people in the world. They all get hired by about 5 companies.

For all the hype that FP gets, there are very few programmers who can actually do it. Writing entire apps in SQL is even harder than that (this is something you can do).

I do understand if somebody struggles with PROLOG, but functional or SQL? Come on!

                  I couldn't agree more, well said. FP is pushed by programming language people largely because it makes the compiler far easier to write so more effort can be done on optimization. Relational algebra even more so. The problem is that it is really hard to work in such programming models and most programmers can't do it.

The dog food metaphor is more often, in my mind, associated with what happens to your menu if you get old and run out of money.

        And I tend to be annoyed by this verbification trend.

      When did dog-food become a verb and what am I to make of it?

      You'll just have to use the term yourself for a while and see if you like it or not!

    oh man... if you think that's something, imagine the company was more than one year old and the whole company was working on whatever the heck this is lol

    got so distracted by the buzz words that I lost interest within the first sentence, slashvertisement at its best. I vaguely remember seing the word python

    Judging from previous posts, I guess I am not the only one that felt annoyed

    "The Mojo standard library, compiler, and runtime are not available for local development yet".

    There's literally nothing you can download and try. They have a very limited online playground and a long list of things that don't work [modular.com].

    At this point it's impossible to tell for yourself if it's a promising new language in early alpha or just Python but broken.

    • The developer does have quite the history of success. He has accomplished things much more complex, so I would give him the benefit of the doubt.

        The developer worked at Google and got a lot of projects on his CV. That isn't the same thing.

          We are talking about the Father of LLVM (or co-father) here. You might as well call K&R as developers who just worked at Bell Labs "and got a lot of projects on their CVs".

          LLVM is the foundation of Rust, Julia, Numba etc. Swift was also his project. So people take him seriously unlike our pet projects.

      No. At this point it's NOT a promising new language. It may eventually become so. Perhaps. Using an emoji as a file extension is not a promising sign.

    Just don't cross the line of ads with propaganda - because the latter puts people away (like shoveling certain reddish language down our throats for some time now)
    O, and a wiki page would've been in place, because - you know - "it's such a revolution in computing"

  • Just as LLVM made it dramatically easier for powerful new programming languages to be developed

    Edit out the word "powerful" and that quote pretty much sums up the recent explosion of "new" programming languages. New is in quotes because most of these are just variations on a theme. The developers of Mojo seem to be actually proud of the fact that they they are attempting to ride Python's coattails.

  • Just claim that it is the most significant development since the invention of fire.
  • did that video have to have that annoying noise in the background ? It was distracting. It did not add anything. Did the authors think that viewers would get bored and switch off without that crap sound ?

  • I read an article on it that said it is, and if you don't want to use the new typesafe, high performance side of it, you can just stick to python syntax and it will all still work (albeit slow maybe).

    Then I looked at mojo "sharp edges" doc and I see all these python things that are not supported in the mojo runtime as I understand what they were saying.

    So which is it? Strict superset (syntactically and semantically) or not? It's kind of important to know, with regard to feasibility of adapting existing pyth
  • Any time they found something didn't quite work great as they developed Mojo, they could add a needed feature to Mojo itself to make it easier for them to develop the next bit of Mojo!

    LISP did that. Smalltalk did that. C did that. C++ did that. Hell, C++ is the dominant language of compilers these days, with every major language getting a frontend on Clang and GCC. Most compilers aim for self-hosting as a goal.

    This is like the "Uber startup disruptor" of PR. Acting like they have invented a new practice, when it's been done for decades.

  • This seems like basically the same concept as the Halide DSL for C++ [halide-lang.org], with two huge improvements:
    1. 1. Python not C++!
    2. 2. It's a true language, so its featureset can be expanded to various new areas.

    Their full launch video [youtube.com] is even flashier and made me laugh out loud, saying "[there's] a crazy complex and fragmented ecosystem where developers are constantly brute forcing everything[....] this is slowing down everyone's ability to innovate!" Because if there's one problem with AI today, it's that the tech

      ...and yes, I get that it's not ready to use yet, and that they are overselling it, and it's not even a superset of Python yet. But I've been following advanced languages for many years and never seen a language that was fast, easy-to-use, with strong metaprogramming AND low-level features that was funded or marketed this well, so I'm impressed! Plus I've long advocated new languages that are supersets of existing languages - hello TypeScript and Enhanced C# - so forgive my enthusiasm. I can see negativity
