Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

So this one I thought I’d answer because I’ve done development in both NET framework and NET core and how it works is different for each (although things will usually work one way or another).

For .NET framework applications, if the program is compiled for windows (the .exe) you can usually run it with mono (you generally don’t need wine, but there’s some caveats that mean sometimes you should use wine). This will include programs with GUIs. If the NET framework app calls other windows programs it is best to run it via wine, you will need to install the net framework within wine, but there’s a winetricks command for that. There are a few things that are generally niche things that do not work in linux net framework’s mono though. By niche the one I can think of, is serial port events. Very annoyingly they all exist, so the program will run but the events will never trigger an action in the programs. Very annoying, but luckily very rare/niche stuff.

For .NET core, you can build directly to linux targets, and if the project you are working on does target NET core, then you can run the binary natively (note: you usually cannot build applications using forms to linux native binaries, for these you should run the windows exe with wine). You can also run the .exe files for this with wine and I’ve rarely had a problem with it.

Note that if you develop .NET applications, you won’t be able to build anything that uses the standard forms GUI under linux. There are other UI frameworks out there you can use that are multi platform. For this reason, for the projects that do use windows forms, I have a VM with windows on that I boot up for this reason.

In short, if you’re just running windows binaries, you will be generally fine with mono for framework and wine for core. For development “it’s complicated”.

For threadiverse (lemmy/mbin et al) there’s not much in it. It’s fairly easy for an operator to curate their instance by pre subscribing to a whole bunch of communities. I run my own instance, barely any users and I’m constantly banning and deleting them for advertising. But I have plenty of content.

I made my own mastodon instance and connected to a bunch of groups. Only two or three are active. There’s not really an easy way to get content without following a lot of people. So anyone visiting my instance will see virtually nothing. If they go to social they will see plenty.

So it’s a bit of a no brainer for most I think.

Yeah, it shouldn’t happen in a release. But, if I had a penny for every time I’ve seen the last minute development that wasn’t tested yet and not even due for the current release squeezed in. I’d literally have a pound, or dollar or whatever else has 100 pennies in.

In a professional sense my experience is that they’re more often the result of under-staffing and rigid, fixed release schedules.

Yeah. I didn’t understand what they meant by the wtf there. Seemed to me someone wondered if the Action would have a localised version of i (making this stay lowercase on a phone was harder than it should be) or if it used the same i. So made a simple test for it.

Not really sure it’s a wtf unless they expected a different result.

Not sure how it is in the US. But here in the UK there’s two ways a business can export.

1: They pre-clear the customs duty and include it in the sales total (so it’s like paying sales tax at the checkout, except it’s the pre-cleared duty fees). Then the parcel has a nice duty paid stamp and goes straight through customs (I guess unless customs are suspicious and check into it).

2: They just charge you the item price with no tax applied. In which case you need to pay local tax and duties applicable once the product arrives. Here it’s a bit different. They will hold it at the local depot and you can either go there and pay + collect, or you can pay online and it will be rescheduled for delivery once you pay.

As others have said, it’s not a scam. There’s no requirement for a business to do option 1, and it’s likely only viable for large businesses to register and have someone/software that knows the various duties required for various countries.

I’ve ordered from newegg and B&M in the past for example, and in both cases the items were pre-cleared and arrived promptly without any hassle.

Maybe there’s something similar for imports into the US too?

Instance level censorship isn’t much for the user to worry about (I run my own, so it’s zero problem for me). Most censorship happens at the group level by group owners, and the admins on the instance the group is hosted.

I still don’t have a problem with it though. You subscribe to a group on a certain instance, you cannot be too surprised if you get censored there.

Yeah but they’re a cheat. They’re lithium cells regulated down to 1.5v. Good ones are rare, when you find good ones they’re generally expensive and because they’re regulated down you generally get 100% battery showing until just before they fail.

I used them for some voltage sensitive stuff, but finding a brand that held a good charge for more than even 50-100 charges was hard.

Nimh is much better for anything that won’t be upset about the voltage too much.

To be fair, I bought a really good mini pc for a home server. The problem is, it was marketed as a gaming pc. But with the on chip Intel HD graphics.

I can understand why this would upset people. For my uses though it was perfect. Sits in the TV cabinet, is quiet yet still quite powerful (intel 12900).

Well for a gamer no real comment. But there is one metric Intel still trashes AMD in for the APU. Hardware video acceleration/encoding. The quality is objectively better on Intel Quicksync.

When getting a home box that also needed to do transcoding, Intel CPU was a requirement. My desktop development/gaming system? Ryzen + NVidia.

It’s not how ActivityPub (at least Lemmy/*bin servers) works. There isn’t so far as I’ve ever seen an API that allows for this within ActivityPub (now specific to Lemmy/*bin implementations there’s the API the browser/apps use that must provide this, but that’s not ActivityPub). It actually looks to be cleverly designed to prevent it. It might look like backfilling is happening because old stuff appears, but there are reasons for this.

How it works from my experience (I did some work on the federation in kbin a year or so ago).

• Instance A subscribes to community B hosted on Instance C.
• Instance C notes this and does nothing. No previous content is sent, only future activities will be.
• User on Instance D already subscribed to community B upvotes a comment on a post in community B.
• Instance D sends the activity to Instance C.
• Instance C sends the activity to Instance A.
• Instance A gets the notice of the upvote, but realises it has no context for the upvote. But luckily the upvote has the comment ID of the comment that it was related to. So, now Instance A makes a request for the comment from Instance C.
• Instance A receives the response from Instance C. But it turns out that comment was in reply to another comment. But the comment contains the ID of the parent comment. So Instance A requests that comment (and any parent comments until it gets the parent post).
• By now Instance A has the information about the like, all comments from the liked comment to the post. These are saved to the database and will appear on the local system.
• For each of the likes, comments and posts. If the user isn’t known locally the profile will also be fetched from their instance and stored locally.

And so old posts and comments will begin to appear as activities linked to them happen. But there isn’t a method to ask for “all the posts in community X” using activity pub. I remember because I was specifically looking for this a year or so ago. It let’s you see the parent object but not any children.

Maybe Mastadon etc does it different? No idea.

And all of this is moot because if I block a User Agent, or I block an AS number/IP block. They’re not getting anything either by ActivityPub or scraping unless they change User Agent, AS number, or both.

I don’t think they’re optimising much at all. I think it’s likely just a modified web crawler but without the kind of throttling normal search engine crawlers use. They’re following links recursively. Then probably some basic parsing or even parsing with AI to prepare the data to make another AI model.

But, they aren’t. They’re not after Activitypub specifically. They’re scraping the whole internet, most of them using clear bot User Agents. So, I routinely block their bots because the AI ones are usually hitting you multiple times a second non-stop. If they started making fake Activitypub nodes they would not be scraping as a bot, and they would want specifically fediverse data. Important to note here though, an Activitypub node doesn’t “collect” data, they subscribe (to mastadon users/hashtags or communities) and then get new data delivered to them. So they wouldn’t get the old stuff.

Having said that, I’ve seen some obvious bots using genuine browser user agents on IP addresses from certain very large Chinese companies. For those I just blocked their whole AS number.

I mean personally I did block all the AI scrapers I could find on my instance, around a month or so ago. There were a lot, mostly unscrupulous, some big names included. Probably should look at the logs to see what’s new.

The amount of traffic was quite significant too. I have a theory that they expect legislation soon, so are not playing nice and slow like crawlers do, but are vacuuming as fast as they can.

But you’re right. Everyone would need to do it, to make a difference.

Yes, instead use rozzers, bacon or filth!

I don’t think it’s rose-tinted glasses really. I think it’s just the change in dynamic. It was definitely different during the “real” classic times (I would say classic to Wrath).

In 2005 when I started playing you needed to group up to get things done really. When you did this you met people. You talked, not with a microphone, but you would be talking. You’d get to know people, they’d invite you to dungeon groups and vice-versa, it would widen both of your in game circles and so on.

When I got to the position to raid, I was on an RP-PvP realm and while there were raiding guilds, many people were in smaller guilds that were either role-playing or guilds of friends. So, there were often raiding groups. I was in one of these, and we had our own guild chat-esque thing that everyone in the group could chat through and of course raids were mandatory voice. Because generally you did need to have communications to raid. This increased your in game circle too.

I still speak to some people now, on social media in various forms that I played the game with in 2005-2010. Some I met, others I never did. I’ve not really played retail much for a while now. But, it’s not the same. To an extent, neither is classic now.

Now, probably an unpopular opinion because I think a lot of people think Blizzard’s actions led to this change in community spirit. I actually think it’s the other way round. I think they saw their player-base changing, and adjusted the game to suit. The side effect is that it put off some of those with a more social gaming mindset for good. But, it would have happened anyway.

Times change, and they just rolled with it.

I’m on NVidia with blob driver, KDE Plasma on wayland on Arch. Yeah, standby to resume is like 50/50 the screen will come back. I just turned off stand-by and kept screen sleep only.

But I’m on desktop so less of a problem for me than it would be for a laptop user.

OK, look back at the original picture this thread is based on.

We have two situations.

The first is a dedicated system for providing navigation and other subsystems for a very specific purpose, with very specific hardware that is very limited. An 8 bit CPU with a very clearly known RISCesque instruction set, 4kb of ram and an bus to connect devices.

The second is a modern computer system with unknown hardware, one of many CPUs offering the same instruction set, but with differing extensions, a lot of memory attached.

You are going to write software very differently for these two systems. You cannot realistically abstract on the first system, in reality you can’t even use libraries directly. Maybe you can borrow code from a library at best. On the second system you MUST abstract because, you don’t know if the target system will run an Intel or Amd CPU, what the GPU might be, what other hardware is in place, etc etc.

And this is why my original comment was saying, you just cannot compare these systems. One MUST use abstraction, the other must not. And abstractions DO produce overhead (which is an inefficiency). But we NEED that and it’s not a bad thing.

Exactly my point though. My original point was that you cannot compare this. And the main reason you cannot compare them is because of the abstraction required for modern development (and that happens at the development level and the operating system you run it on).

The Apollo software was machine code running on known bare metal interfacing with known hardware with no requirement to deal with abstraction, libraries, unknown hardware etc.

This was why my original comment made it clear, you just cannot compare the two.

Oh one quick edit to say, I do not in any way mean to take away from the amazing achievement from the apollo developers. That was amazing software. I just think it’s not fair to compare apples with oranges.

It does. It definitely does.

If I write software for fixed hardware with my own operating system designed for that fixed hardware and you write software for a generic operating system that can work with many hardware configurations. Mine runs faster every time. Every single time. That doesn’t make either better.

This is my whole point. You cannot compare the apollo software with a program written for a modern system. You just cannot.
