  • I started playing with rust last week (just converting a couple of C# projects so far), and I’m going to say that once you understand that mutexes/rwlocks are wrappers around the actual data, it (to me at least) feels better.

    Don’t get me wrong, it’s an absolute headache for anyone that’s acquired intermediate or better skill in one of the Cx languages. The paradigm shift is still hitting me hard. But this was one of the differences I actually think is an improvement in probably most use cases.



  • There’s a certbot addon which uses nginx directly to renew the certificate (so you don’t need to stop the web server to renew). If you install the addon you just use the same certbot commands but with --nginx instead and it will perform the actions without interfering with web server operation.

    You just then make sure the cron job to renew also includes --nginx and you’re done.







  • Now I’ll upset some people here, I’m sure but…

    Here in the UK, you can see how decent an area is using this method.

    Go to the nearest Tesco Extra. If they have the coin traps on the trolleys, probably a dodgy area. If they don’t, not so dodgy area.

    In both cases, you’re going to find the trolleys are generally not left lying around. Read into it what you will.

    I only use Tesco extra as an example because from my experience other supermarkets either have the coin traps, or don’t. It seems only Tesco (correct me if I’m wrong) vary the behaviour by area.



  • I mean for advert breaks, there are projects to do this to recorded tv automatically (with varying degrees of success depending on the config and the channel).

    That is, you record the TV from either a TV receiver card, or streamed live channels to disk, then run this process on the mkv/mp4/ts, and it will either create a set of chapters marking the ads (so you can skip them), or it will just remove them entirely.

    I don’t think it would transfer to “live” TV quite so readily though. Because it does scan the whole program to find things like logos etc to help work out where the adverts are. But, I mean a lot of the work has been done.

    For removing all product logos. I mean, I bet we’re not far from the processing power to make it possible. But, probably a fair bit of effort needed.

    I can imagine the “AI” chips being neutered for these kind of tasks, like the “low hash rate” Nividia cards.


  • I think this overall is a better idea. I’m going to say this because, I thought I’d look into rust today. So I installed it, setup vscode to work with it etc. And it’s all up and running. I thought I would port over a “fairly simple” C# project I wrote recently as a bit of a test.

    While I’ve generally had success (albeit with 30+ tabs open to solve questions I had about how to do certain things, and only making it about 20% into the task) I’m going to say that it’s different enough from C, C++ and C# (all of which I can work with) that I really don’t think it is fair to expect C developers that have day jobs and work on the kernel in their spare time to learn this. It’s fundamentally different in my opinion.

    Now, I don’t condone any bad attitude and pushing away of rust developers from the project. But there’s no way they’re going to want to do anything to help which involves learning a new language. It’s just not going to happen.

    Likewise, C is not a language most new developers are learning. So, I feel like over time there won’t be so much of an influx of new kernel developers and any Rust based kernel could find itself with more contributors over time and taking over as the de-facto kernel.

    In terms of Redox (not looked into it yet). So long as there’s a different team working on the userspace tools. I would say the main task should be getting a solid kernel with drivers for most popular hardware etc in place. The existing GNU tools will do until there’s a kernel that is able to compete with the C one. But that’s just my opinion.



  • Here’s what I think. Both opinions are correct.

    Rust is sufficiently different that you cannot expect C developers to learn rust to the level they have mastered C in order to be working at the kernel level. It’s not going to happen.

    I don’t really know too much about rust. Maybe one day I’ll actually mess around with it. But the one time I looked at a rust git repo I couldn’t even find where the code to do a thing was. It’s just different enough to be problematic that way.

    So I think probably, the best way IS to go the way linus did. Just go ahead and write a very basic working kernel in rust. If the project is popular it will gain momentum.

    Trying to slowly adapt parts of the kernel to rust and then complain when long term C developers don’t want to learn a new language in order to help isn’t going to make many friends on that team.




  • Nah my local expensive hipster craft beer place usually has 6 on tap. One will usually be a UK style ipa, 2-3 others will be a mix of USA/oceana style pale ales. One local brewery and one non pale ale (blonde, Porter, stout etc)

    But you really can’t tell until you try them.
