r00ty

The current thing I’m working on (processor for iptv m3u files) isn’t public yet, it’s still in the very early stages. Some of the “learning to fly” rust projects I’ve done so far are here though:

https://git.nerfed.net/r00ty/bingo_rust (it’s a multi-threaded bingo game simulator, that I made because of the stand-up maths video on the subject).
https://git.nerfed.net/r00ty/spectrum_screen (this is a port of part of a general CPU emulation project I did in C#, it emulates the ZX spectrum screen, you can load in the 6912 byte screens and it will show it in a 2x scaled window).

I think both of these are rather using Arc<RwLock<Thing>> because they both operate in a threaded environment. Bingo is wholly multi-threaded and the spectrum screen is meant to be used by a CPU emulator running in another thread. So not quite the same thing. But you can probably see a lot of jamming the wrong shape in the wrong hole in both of those.

The current project isn’t multi-threaded. So it has a lot of the Rc/Rc<RefCell> action instead.

EDIT: Just to give the reason for Rc<RefCell> in the current project. I’m reading in a M3U file and I’m going to be referencing it against an Excel file. So in the structure for the m3u file, I have two BtreeMaps, one for order by channel number and one by name. Each containing references to the same Channel object.

Likewise the same channel objects are stored in the structure for the Excel file that is read in (searched for in the m3u file structure).

BTreeMaps used because in different scenarios the contents will be output in either name order or channel order. So just better to put them in, in that order in the first place.

The problem with rust, I always find is that when you’re from the previous coding generation like myself. Where I grew up on 8 bit machines with basic and assembly language that you could actually use moving into OO languages… I find that with rust, I’m always trying to shove a round block in a square hole.

When I look at other projects done originally in rust, I think they’re using a different design paradigm.

Not to say, what I make doesn’t work and isn’t still fast and mostly efficient (mostly…). But one example is, because I’m used to working with references and shoving them in different storage. Everything ends up surrounded by Rc<xxx> or Rc<RefCell<xxx>> and accessed with blah.as_ptr().borrow().x etc.

Nothing wrong with that, but the code (to me at least) feels messy in comparison to say C# which is where I do most of my day job work these days. But since I see often that things are done very different in rust projects I see online, I feel like to really get on with the language I need a design paradigm shift somewhere.

I do still persist with rust because I think it’s way more portable than other languages. By that I mean it will make executable files for linux and windows with the same code that really only needs the standard libraries installed on the machine. So when I think of writing a project I want to work on multi platforms, I’m generally looking at rust first these days.

I just realised this is programmerhumor. Sorry, not a very funny comment. Unless you’re a rust developer and laughing at my plight of trying to make rust work for me.

I’ve been using thinkpads as a work laptop since they were branded IBM Thinkpad. So, I have nothing further to comment.

This does tally up with what I’ve been hearing. Where I’m at there’s been a few hires straight into senior. I’ve not heard of an official junior freeze. At the same time it’s been a long time since I’ve seen a new one.

The problem, as I commented prior, is that if we no longer bring in junior devs to gain this kind of experience, we lose the flow of junior -> senior. But in most places, the people making the decisions won’t consider anything beyond the end of the current fin year.

I don’t think developers are doing it. It’s managers making this kind of decision I’d say.

I’ve been told about companies in the same field as mine with a hiring freeze on juniors. So it’s kinda second hand.

I think it goes further than that. There’s two things happening with regard to AI and software development.

1: Stack overflow has become less common as a resource to solve problems. This, as you say has a problem of input into LLMs for future problems to solve.
2: Junior developers are being hired less because of AI. I assume the idea is that seniors will use AI in the same way they would usually use juniors. Except, they’ve done what business always does. Not think one bit about the future. Today’s senior developers are yesterdays junior developers.

The combination of AI performance drop due to point 1, and the lack of new developers because of point 2 makes for potentially, a bad future for the profession.

We used to have it terrible in the UK in the 90s and 2000s. Basic ADSL was trialled in 1999 and available in maybe late 2000 I think. But it stagnated for a while.

When it came to fibre, interesting things are happening. As well as the “national” (although privatised) telco installing it, there are many independent companies fitting it. Where I live I have the option of the official telco (1000/110) and a private company (1000/1000). Of course I chose the latter :P

Some people have 3 or more options.

Yeah in the future there might well be a handful of overall winners that vacuum up the losers and carve up the territory. But right now, it’s a good time for the normal people… At least for internet.

EDIT: Just to add, some are ISPs and will only sell their own product. Some are wholesale, so even if they’re the only company in your area, you can often buy from multiple ISPs through them.

I’m on a pretty old version of mbin (I have some modifications I made for federation issues back when it was kbin). I need to spend a weekend to pilot an upgrade and make sure I can run it safely live.

But even then it’s better in some ways already and I never feel like I’m missing something from lemmy. But I think just calling the whole thing lemmy puts off people that are seeing things through a political lens.

Pretty sure that’s only true about Lemmy. There are other threadiverse apps. The mistake is people calling the threadiverse lemmy.

The US did in 2016 too. It’s just for some reason, a lot of you want to do it all over again :P

I think it had its uses in the past, specifically if it had the memory backup to prevent full array rebuilds and cached data loss on power failure.

Also at the height of raid controller use (I would say 90s and 2000s) there probably was some compute savings by shifting the work to a dedicated controller.

In modern day, completely agree.

I’m sure I’ve seen paid software that will detect and read data from several popular hardware controllers. Maybe there’s something free that can do the same.

For the future, I’d say that with modern copy on write filesystems, so long as you don’t mind the long rebuild on power failures, software raid is fine for most people.

I found this, which seems to be someone trying to do something similar with a drive array built with an Intel raid controller

https://blog.bramp.net/post/2021/09/12/recovering-a-raid-5-intel-storage-matrix-on-linux-without-the-hardware/

Note, they are using drive images, you should be too.

The OP made clear it was a controller failure or entire system (I read hardware here) failure. Which does complicate things somewhat.

Yeah, I was going to say. Not pension, but I put money into two different blended portfolios (I didn’t choose the contents, just the two choices from a list). I started it in Feb 2021 and the overall gain has been over 35%. I have no idea what the pension fund put their money into there, but it seems like some bad choices.

OP should check the options they have.

Yeah, but that’s just because “nobody wants to work”

Yeah, I’m quite sure it’s a deliberate activity to dissuade against private email servers. Keep everyone’s email “in the club”. Once you’ve got this much working you need a whole suite of tools to deal with the HUGE amount of spam you need to filter. It can be a hell of a lot.

kbin/mbin does have some mastadonesque facilities. So it straddles the line between threadiverse and I dunno what we call the mastadon side.

IRC was “kinda” federated. You needed to convince a server already in the network to accept your server. But in the early days requirements were quite low.

BBS was not really federated (except Fidonet I guess).

Usenet, I guess it kinda was. But only ISPs were really running NNTP servers. Only they and unis really had the resources to too.

You CAN do the full list of things to get accepted there. But you only need to fail a SINGLE test to get sent to junk mail jail.

To not be put to junk you need all of the following (oh and this can and will change one day and you’ll go straight to junk)

• SPF configured
• DKIM configured with valid keys applied to DNS
• DNS secured with DNSSEC, with validated keys passing all minimum requirements
• DMARC configured for domain
• Your mail server NOR the entire network on a DNSRBL. For example right now my mail server is hosted on OVH (moving soon) and it will go to junk, and in the hotmail/outlook headers it makes clear this is the only failure (-0.2 points, enough to go straight to junk mail jail)

Not sure if I missed any there. It’s been a while since I set all this crap up.
