  • I found the title of that section slightly triggering too, but the argument they lay down actually makes sense. Consistency helps you to achieve correctness in large codebases, because it means you don’t have to reinvent what is correct over and over in separate pockets of the codebase. Such pockets also make incremental improvements to the codebase harder and harder, so they do come back to bite you.

    Your example of vendors doesn’t relate to that, because you don’t control your vendor’s code. But you do control your organisation’s.








  • You’re ignoring the fact that for many projects it does work.

    It only needs to be perfect if you want to run 100% Node.js software unaltered. While that may be a lofty goal, it’s also an infeasible one.

    That doesn’t mean imperfect support is futile though. By your logic, Bun has no right to exist because it only supports Node.js APIs and doesn’t have noteworthy APIs of its own, and they’re not perfect either. Yet they seem to be at least as successful as Deno is.

    Or for an example in a different domain: Your argument would state that a project like WINE shouldn’t exist because it doesn’t have perfect compatibility with Windows, and it disincentivizes development of Linux games. Yet it is largely thanks to WINE that Valve has been able to make the Steam Deck and that Linux gaming is finally taking off.

    I think what your argument fails to take into account is that you need a significant amount of users to make any impact on the market. And many users have legacy requirements that they can’t throw out overnight, so you have to support those legacy environments. And even with imperfect legacy support you can support your users, especially if the users are willing to make a few changes here or there. But if you have no legacy support, you also get no users except those that have niche greenfield requirements.

    So instead of trying to replace NodeJS or offering an upgrade path for existing Node projects, incentivize formation of ecosystem around Deno

    They are incentivizing their own ecosystem. That’s what Jsr.io is all about. But the world isn’t black and white. They can do more than one thing.









  • I don’t know about your workplace, but if at all possible I would try to find time between tasks to spend on learning. If your company doesn’t have a policy where it is clear that employees have the freedom to learn during company time, try to underestimate your own velocity even more and use the time it leaves for learning.

    About 10 years ago I worked for a company where I was performing quite well. Since that meant I finished my tasks early, I could have taken on even more tasks. But I didn’t really tell our scrum master when I finished early. Instead I spent the time learning, and also refactoring code to help me become more productive. This added up, and my efficiency only increased more, until at some point I only needed one or two days to complete a week’s sprint. I didn’t waste my time, but I used it to pick up more architectural stuff on the side, while always learning on the job.

    I’ll admit that when I started this route, I already had a bunch of experience under my belt, and this may not be feasible if you have managers breathing down your neck all the time. But the point is, if you play it smart you can use company time to improve yourself and they may even appreciate you for it.



  • You can use the regular data structures in java and run into issues with concurrency but you can also use unsafe in rust so it’s a bit of a moot point.

    In Java it isn’t always clear when something crosses a thread boundary and when it doesn’t. In Rust, it is very explicit when you’re opting into using unsafe, so I think that’s a very clear distinction.

    Java provides classes for thread safe programming, but the language isn’t thread safe. Just like C++ provides containers for improved memory safety, and yet the language isn’t memory safe.

    The distinction lies between what’s available in the standard library, and what the language enforces.




  • Great suggestions! One nitpick:

    But in principle I find this quite workable, as you get to write your CI code in Rust.

    Having used xtask in the past, I’d say this is a downside. CI code is tedious enough to debug as it is, and slowing down the cycle by adding Rust compilation into the mix was a horrible experience. To add, CI is a unique environment where Rust’s focus on correctness isn’t very valuable, since it’s an isolated, project-specific environment anyway.

    I’d rather use Deno or indeed just for that.



  • I would say at this point in time it’s clearly decided that Rust will be part of the future. Maybe there’s a meaningful place for Zig too, but that’s the only part that’s too early to tell.

    If you think Zig still has a chance at overtaking Rust though, that’s very much wishful thinking. Zig isn’t memory safe, so any areas where security is paramount are out of reach for it. The industry isn’t going back in that direction.

    I actually think Zig might still have a chance in game development, and maybe in specialized areas where Rust’s borrow checker cannot really help anyway, such as JIT compilers.
