loom VS Home

It's more accurate to say Loom is [a particular type of] continuations in the JVM, which can be used to implement green threads / fibers.

You can see the implementation of VirtualThread here: https://github.com/openjdk/loom/blob/fibers/src/java.base/sh...

This uses the internal 'one-shot delimited continuation': https://github.com/openjdk/loom/blob/fibers/src/java.base/sh...

So, at least in principle, there is scope for other styles of concurrency to be implemented over this.

Loom is actively developed https://github.com/openjdk/loom

Currently the Thread public constructor defaults to platform threads to be fully backwards compatible. So all libraries must be updated to support the new model.

Indeed, by criteria of community drama, .NET is also too immature for use. See [1], as the conclusion of that.

Saying that outcry was about one tiny decision is like saying WW1 was because an Archduke got assassinated.

Microsoft's handling of .NET 's OSS community has been haphazard at best. Just a week or two prior to the 'dotnet watch' debacle, there were issues and concerns with the .NET Foundation that led to the Executive Director stepping down [0].

I bring this up, because in many cases the perception is that there is -still- lock in, just in a different fashion.

By that, I mean, if you Ask a typical .NET developer what they use, they'll probably say ASPNETCORE, EF Core, maybe you'll hear Hangfire, MediatR, RestSharp, or Dapper.

So, you've got a bunch of .NET devs that -only- know Microsoft technologies for the most part. Yeah there's some other stuff like MongoDb, Kafka, Redis, stuff like that, but It's not very frequent you hear about teams reaching out to other technologies.

It's very rare I hear people bring up Linq2Db, a beautiful* Micro-ORM that is best described as a type-safe, extensible SQL DSL. Or Websharper, a really-freaking-cool library that basically lets you transpile your C#/F# code into Javascript and/or Reactive HTML, complete with seamless server calls if you'd like.

You might run into some interesting things at different places. One shop I was at used MassTransit, which was kinda cool. I've wound up using Akka.NET a few times in the past, which has always been super fun.

The end result of this though, is the -perception- of what .NET Developers are like. And sometimes those perceptions are real. I remember the dev that felt Dapper was some sort of 'black magic' and would stick to writing DataReaders and or datatables by hand, and another that was so against the idea including Non-MS tech in a project that it wound up costing him his job; he insisted there was a way to get EF to do things in a performant way (answer: not sanely, and not easily the way the app was built on an arch level,) and refused to accept a PR that solved the problem with Dapper.

He wound up doing the thing I've seen a -lot- of .NET developers do; fight the Framework.

To be clear here, I'm not referring to the BCL. It's not always perfect (I'd love for an analogue to SSLEngine, please?), but it's -fine-. I'm referring to bits like ASPNETCORE, EFCore, SignalR, and Microsoft.Extensions.(DependencyInjection/Logging) where developers wind up getting in awkward tarpits around some weird edge case because of a business requirement or some other decision that, unfortunately, can't be undone.

Or are just plain 'well, that sounds sensible in theory' like "I would like to update N rows in an new status that are older than 1 month and set to overdue, and not have it be N update statements." Maybe EF does that now, but last I knew the answer was not really.

At my first 'Real' Dev job, we were a .NET shop, that often had to 'fight the framework' (it didn't help that we were on an Oracle Backend, which made -everything- more of a PITA before we discovered Dapper.) When the .NET guys hit one of these roadblocks, it would often take sprint after sprint of fighting to either have no solution, or have a solution that would render the app hard to maintain. The newer teams using Java? They didn't have those problems. We later heard they had 5 different ORM-ish libraries in use over there. At the time, a lot of the .NET devs kinda treated it as a sort of derision. 'hows somebody gonna understand it?'... But the Java teams delivered. It is also worth considering, maybe those were the best libraries to solve the problems that the app in question needed to deal with.

And that's kinda the 'mindset' that is a set of .NET developers that fit the stereotype; if it's not an app that fits their cookie-cutter world, they break down and can't understand it. In other words, they're afraid to step outside the box, which means they're less likely to think outside the box.

The typical 'litmus-test' of this type for me is a sliding scale based on their past/current experience with other languages and willingness to work with them.

* - I do some contribution work to Linq2Db, so my opinion may be a little biased.

I've heard this so many times within the last 10 years, and it's always after they've done something really stupid. At least in the FOSS realm, regarding microsoft, people are just so naive it's laughable. Like here where everyone is responding by pretty much saying "oh, it seems I've signed my rights away. I sure hope Microsoft doesn't abuse this in the future" ... I stopped feeling bad after reading responses.

> The primary goal was to centralize billing to give member projects access to additional GitHub services. A secondary goal was to ensure the continuity of membership projects, using requestable admin access, as just described.

Seems like a pretty obvious lie.

One of the people in the issues forum post about this pointed out how they had not only failed to give them "more services," but rather taken those "services" away over time. (1)

Why is no one else calling the obvious here?

Their foundation exec director got mad when someone called bullshit on giving the foundation admin over their repo to enforce "code of conduct." So the foundation exec director set out to get them to add the foundation's account to the admin list on their repos so that they could be taken control of in the middle of the night with no warning.

This is what happens when you have self promoting people with a privileged political status in administrative positions.
