> I believe the .ML stands for Marxist Leninist

According to the link you posted, I think you're talkong about lemmygrad.ml. lemmy.ml is hosted by the original Lemmy developers.

The original Lemmy developers are hardline Marxist-Leninists, they make no secret of this.

Tire-fire is spectacular compared to dumpster fire. Highly energetic thick black smoke probably visible from space shuttle with naked eye.

segfault, leak and hang are also fun ones. Apparently the massive memory leaks in the python integration has never been fixed. Not surprising, one look at hardware/plugins/Python*.cpp is bad for your health.

> organizations doing hardware, marketing, sales

Still sounds simpler than what Spotify does.

Just thinking about dealing with payment processing, regulatory environment of music licensing, customer support, and record labels around all countries on which they operate makes my head hurt a little.

But then again, your bad take is the reason I keep coming back to HN. I always find it amusing how people here always seem to have all the answers for things they never worked with. Most of the times I think people being butthurt for whatever reason.

> payment processing

This is outsourced.

> customer support

"Can't find the solution you're looking for? Here's how to get help from our experts. Note: We currently don't offer support by phone."

And half of what they do have is outsourced to "community members".

> regulatory environment of music licensing

This, this is what they do. So that's something. Is it 9600 people something? Apparently not since they already shaved off 6% of the work force earlier this year. It would seem their own CEO appears to agree with the take they are overweight.

Selling hardware around the world has tremendous regulatory burden as well. If you can't imagine the complexities of designing, sourcing and selling hardware products around the world maybe think harder?

Let the chips fall where they may. It isn't like it's the first or even biggest layoff for Spotify this year.

Simple, rock solid functionality. If you want more, write scripts.

I really like the approach.

Don't ever open that C++ code base unless you have a barf bag.

I started making contributions and gave up because I have better things to do with my time then ruin my soul.

I will also note that they stole the MQTT protocol from Home Assistant - so at least they need ideas from elsewhere. (ie openzwave died so domoticz needs to rely on the same NodeJS subsystem infrastructure of HA)

I love the concept of domoticz - lua, but my god the architecture and implementation is a tire fire.

In the 90s I used to edit out CSAM related groups, from the downloaded list in Netscape's built in NNTP client. Customers who were surfing usenet for the first time were reasonably horrified by the group names.

After a time I got unhappy about this and went to see if I could determine a physical hosting location of the content. I don't recall the particulars, just that I came up with an AT&T subsidiary - something polkadot - sitting at a Canadian address, near the US border.

I wasn't willing to reach out to the FBI blindly and couldn't locate anyone who know anyone in the bureau. I knew someone who knew the head of the [state] Family Association and that person was well connected politically. After some back and forth I gave up on the whole thing. That guy was fairly obsessed with stamping out homosexuality and couldn't be bothered with abused children. I moved on.

This list gets downloaded from whatever server you configure and is then local to your machine. Editing it would only affect what you see on your own client.

> After a time I got unhappy about this and went to see if I could determine a physical hosting location of the content.

Usenet is a distributed system - every server that didn't filter the group was hosting the content. They were typically viewed as common carriers.

(It sounds like you were tracing your own ISP's server?)

On that note some from upstate New York may remember that the attorney general tried to garner votes by raiding and seizing servers from a few local ISPs (Dreamscape, RIP), which in the end didn't work out.

> I wasn't willing to reach out to the FBI blindly and couldn't locate anyone who know anyone in the bureau.

The FBI was quite well aware of the content on Usenet and very adept at navigating it in its heydey. They used it in a number of investigations to track down producers including breaking into trusted rings that communicated with PGP encrypted communications on Usenet. You wouldn't have informed them of anything they didn't know.

alt.binaries killed usenet.

Apart from pron clogging up bandwidth, alt.binaries became a good vector to distribute viruses, child pron, and a bunch of other things that ISPs, and their dial-up customers, were becoming increasingly concerned about. Its openness in an increasingly more dangerous, scammy, and criminal world was always going to be its own undoing. There must have been a stage where Pamela Anderson took up most of the world's storage and bandwidth just from synchronising usenet feeds.

> alt.binaries killed usenet.

In 2023 Usenet is solely commercially viable for alt.binaries.

And business relations in each of the markets. Marketing as well, editorial content, so on and so forth.

I feel sometimes that a lot of the HN folks work on small-scale companies, releasing MVPs and don't have much of an idea about the operations side of a larger operation. It's easy to think in MVP terms, it's really, really hard to understand the nuances (and costs) that scaling that to hundreds of millions of users across dozens to hundred+ countries entail.

Some of us work/worked for organizations doing hardware, marketing, sales to every corner of the planet and dealing with supply chain with 1/8 of that workforce though (more than 2 decades ago - productivity should be better now). Spinning this as anything more than gross overhiring that is going to correct either in dribs and drabs or spectacularly sounds like complete bullshit to those that had been around a few bust cycles and worked in other industries.

Just looking at a snippet of code:

    // Assumes zmm is bitonic and performs a recursive half cleaner
    template <typename vtype, typename zmm_t = typename vtype::zmm_t>
    X86_SIMD_SORT_INLINE zmm_t bitonic_merge_zmm_64bit(zmm_t zmm) {
      // 1) half_cleaner[8]: compare 0-4, 1-5, 2-6, 3-7
      zmm = cmp_merge<vtype>(
        zmm, vtype::permutexvar(_mm512_set_epi64(NETWORK_64BIT_4), zmm), 0xF0);
To me, this why AVX didn't get widespread use. The code is practically hieroglyphics.

If you want humans to use a performance feature, it needs to be easy to use. Preferably fully integrated into the compiler so that you don't need to be aware of it at all.

The level of abstraction is wrong - When they invent AVX1024, recompiling this code won't make use of it. Yet the code itself is probably harder to understand and reason about than just a few lines of assembly code.

This is flat out false. The rest of the comment is therefore superfluous.

Nice effort, and its something. But something may not be good enough to solve hard problems.

Can simulated hospital simulate efforts by staff to quickly add into many charts a medication Rx - by taking one patient note and copying 1 note, then pasting that into several?

Does it simulate staff forgetting the dosage was not edited after pasting into all those charts ?

Or staff not logging out of their userID, to avoid the need to log in every time someone needs to add a note/document into a chart? So that , in fact, the doc added by Dr Smith, was actually done by his assistant Tully?

Life is complicated. People use systems in wild and unexpected ways.

Real solutions require real data.

What CPOE system involves notes? None of the handful I've used in the US.

No modern EMR here involves any copy pasting for orders.
