Does anyone use Ada in 2023? Back in college (~2008), I had a prof who was obsessed with it but AFAIK almost nobody used it even back them.

I think it's still somewhat common in defense and safety of life type applications, and not much outside of those niches

Aerospace, defense, and safety critical systems still use it. It's less common these days but still out there. Ada 2012 is pretty nice if you're going to be writing imperative/procedural code anyways.

  I worked for a defensive contractor in the early 2000s. We had MS2 and ATC programs in our facility. Anything that had to do with the operations of ATC was written in ADA. Almost all the guys I worked with went to school at Embry Riddle. Pretty sure those systems are still written in ADA.

  - Jtsummers 3y ago
    I'm not sure "replaced" so much as "didn't grow" or "didn't grow as fast". Even in the 90s when the US DOD mandated Ada it wasn't used universally in defense projects because people got waivers for it. As the number of projects grow if Ada's not growing as fast as the others in adoption then it's getting a smaller and smaller share of the market. C and C++ took a lot of the marketshare in newer developments and rewrites of older Fortran, JOVIAL, and assembly systems. So as a percentage of the market in the aerospace, defense, and safety space it has shrunk. In absolute numbers, I'm not sure if there are more or fewer systems developed and currently being maintained in it than 20 or 25 years ago. But C and C++ have definitely grown in that space.

      Thanks, the usual sentiment with C and C++ is that it's unsafe to make anything beyond a hello world. Happy to hear that defense is using them. Last time I had to write Ada was in university!

I graduated recently and my first project out of college was in Ada. It was defense-related. I have also heard rumors of banks still having some ada code. My impression of the language is that it is a lot close to C than other languages like Java or Rust.

In France I did learn Ada at computer science school. Maybe because it is useful for the aerospace and aviation industry ? Or because teachers were used to it and deemed it was great to learn programming in a rigorous manner. I have to say at least when you're coding in Ada there is no ideological fights over functional programming or silly design patterns from OOP. Refreshing.
- kokorozasu 3y ago
  The ideological fight that occurred at my job where the project was in Ada was that the most senior programmer didn't want to use git.

    ...What does Version Control System have to do with choice of programming lang? Do I even want an answer?
    - cmrdporcupine 3y ago
      There is, unfortunately, a cohort for which no other version control system is allowed to exist and git is somehow the final answer.

    I am a big proponent of having proper liabilities across the industry, just like any other industry. As a software enginneer professor of mine would joke, general computing quality is akin to buying a pair of shoes that randomly blow up if tied incorrectly, and people have been educated to put up with it. With any other industry, if one buys something that doesn't properly work, usually the first reaction is to return to the shop and ask for the money back. Thankfully digital stores, warranty contracts in project delivery, and ongoing cybersecurity laws, are already some steps into the right direction, yet there is still too much to be done.

    C is used in situations where choose doesn't have to be reliable - wanna expand? In my superficial understanding of computers, Linux is the paragon of reliability, so naively I would say that shows that C is good enough. However, in also aware that some instructions don't have such a great view of Linux, but I don't know much.

The same question can be asked about many languages that are very actively used. Just not by web army. From my personal experience - I use many languages and I mostly base my choice on perceived ROI for particular project / situation. I could not give a flying fuck if "anyone still uses those in 2023" .
- yjftsjthsd-h 3y ago
  ROI is substantially influenced by the ecosystem; the more libraries and documentation are published, the better the ROI.

    Also ability to hire or train people fast enough. It should not be your only consideration but it should be factored in.

      I am very small and never needed more than couple at subcontractors of the same time. With the whole world being at my disposal I've had zero problems finding decent freelancers for any language.
