Yes, its damn true.
SpaceX in its recent launch Dragon 2 Flight has used a technology based on Chromium and Javascript

So Cheers to Javascript. What are your views on this ?

Node.js doesn’t stop from running other operations because of Libuv, a C++ library responsible for the event loop and asynchronously handling tasks such as network requests, DNS resolution, file system operations, data encryption, etc.
What happens under the hood when Node.js works on tasks such as database queries? We will explore it by following this piece of code step by step.

Nobody told the astronauts, right?
Hope so
lol
Yes true, it is all about stronger determinism guarantees.
Also, I agree in case of garbage collected (GC) Functional Programming languages, GC can offer stronger determinism due to immutability imposed by these languages which make them realtime capable. Even in case of Java, there are some GC algorithms can offer determinism guarantees.
So in the end, any language runtime, if it can provide stronger determinism guarantees can be used for mission critical systems.
Brendan must be so proud his passion project broke through the stratosphere, (even if only for a UI). 🌟
I wonder why CommonLISP (or any robust LISPy code system) isn't used more ubiquitously for highly-dependable systems.
Don't know a whole ton about C or C++, just know LISP can address all their concerns plus virtually everything else in Computer Science (being based of Church's λ-Calculus) with an AST comparably faster, safer, and superiorly abstracted than C.
Am I tripping?
I do not think that the people of spacex are improvised if they chose this technology for something it should be and achieved a level of maturity much higher than most think. I think this opens new doors for js and the power he is coming to have.
Simple: Why not? They're both mature and extremely versatile technologies.
It is not about JavaScript maturity; it is about design choice. Garbage Collectors based languages are not used in mission-critical tasks because they may turn non-deterministic. It is not with C and C++ because, as a programmer, you control all the aspects.
I agree with what you say. Though it was my understanding that JS and Chromium were only used for UI purposes. And for those these two technologies are mature enough to do the work.
I don't think SpaceX would use JS and Chromium for mission-critical parts. I also assume that there are overrides in place in case the touch screens or their UI stop working.
Yes, equivalent hardware overrides are in place.
Yeah Exactly they are mature now!
I presume it was not the programming language's fault that those Boeing planes crashed tragically last year. So it won't be JavaScript's fault if things go wrong here. It's just one choice in a set of many tools to get the job done. Hopefully all necessary precautions were made and it was not used to do the things the language might be terrible at.
I suppose so. Human error aside, those folks at SpaceX look like they really know what they are doing. 🤪
This sheds a very ugly light on SpaceX and their commitment to quality. I mean, managing something as risky and complex as a rocket with a web browser and a language as frail as Javascript? A language that converts everything in everything else, making equality not transitive? A language that allows this

No, definitively it is not acceptable, even if it controls just some minor stuff. A bug there could trigger a cascade.
Yet they managed to dock into the ISS successfully. Is that unacceptable to you too? You would've coded the ui with assembler I assume.
People trash languages just for trashing them. It literally doesn't matter if you get to space with that, you won't be taken seriously. I don't find the logic in that argument.
Bugs speak more to the developer than the language. People bash JavaScript because they jump in without understanding it.
Using any language or runtime is acceptable as long as they handle the risks properly.
I wonder if they added an F5 button? Just in case...
Haha, I bet they have Ctrl+R too!
Typescript? I hope?
Javascript a strong Script
They might be used tensorflow js
No. They are using Javacript for UI Interface
I wonder if they should have gone with Typescript atleast although while I was learning Typescript, I was feeling that its too verbose and maybe making the codebase a lot bigger and complicated at someplace by forcing us to declare types again and again. There are subtle Typescript specific behaviour that might just cause debugging harder but SpaceX should and I dont know if they already have but they should conduct an AMA or podcast or conference about challenges and choices they faced and made with regards to software.
Make sense 😂
Good stuff!
Try this out first
Interface as in UI.
Yeah.
