350% more _than assumed_ (because people drive them like hybrids and don't charge them)

They aren't inherently more polluting.

This isn't just google, it's every company with contractors and employees.

Microsoft learned the hard way to not treat contractors like employees. https://www.reuters.com/article/businesspropicks-us-findlaw-...

Nobody else wants to learn that same lesson.

THIS case is exactly why all these companies do this.

Your post is only partially correct. Even with completely open firmware, or at least a documented interface, the biggest roadblock would become be abysmal state of OSS digital image processing. Engineers at major smartphone and camera companies are paid top dollar to improve how the images are processed, this is no laughing matter and is obvious when you compare the image quality from a no-name chinese brand with Samsung or Apple even though they are using the same exact sensors.

FOSS smartphones such as the Pinephone would then need a whole bunch of accelerators to perform such computations because the general purpose CPU would be too slow for that, and image could take seconds to finish processing and get saved in the gallery. But at that point Pinephone itself would not have enough expertise for such a design and everything would crumble.

... to add to your point, then take companies like Google who rely heavily on ML to improve the quality of the photos further and the distance between "RAW data off sensor" and "the best Samsung/Apple/Google can generate" is a HUGE gap.

Some quick questions: - are you using an already-existing HTTP engine, like Jetty or Tomcat?

- how do virtual threads fit into a web framework?

- do virtual threads make debugging more difficult? (A more general JVM question, I suppose)

- any performance / readability benefit, or just a coolness factor?

rkalla · 3 years ago
Nothing to do with the project, but I read through it, so...

1. It's built natively on Jetty - very tight integration, not just some libs running in a Jetty container.

2. Web is inherently Request/Response - all of this can be handled with dramatically less resource requirements using Virtual Threads. Web is sort of the absolutely-best-use-case for Virtual Threads where as a Game Engine would be the opposite of that (one critical rendering thread and MAYBE a few extra long-lived threads for processing physics, audio, etc.)

3. I haven't tried debugging a Loom project but it's been in incubation for just under 100 years so I have to imagine this has been figured out.

4. About twice the throughput and 1/2 the latency of full OS threads - https://github.com/ebarlas/project-loom-comparison

rkalla commented on Java is very fast, if you don’t create many objects   blog.vanillajava.blog/202... · Posted by u/Tomte

I used an approach similar to Peter's here to both an old streaming parsing library as well as a GUI (event handling) library -- effectively, re-use the same instance of the event shell with new data every time an event fired and copy the data out if you need to retain it for a long-lived operation or persistence, otherwise calculate and move on... the reduction in object creation overhead was significant and performance increase was around +30% for doing this in the two individual use-cases... BUT, the API was like a loaded gun pointed at your face.

I knew what I was doing (with it) so it wasn't a problem, but if I over open sourced the API and provided it as a library I would envision a large portion of the population trying to handle the events in a multi-threaded context or throwing them into a List only to find the values changing on them during use (while the parser was still running on another thread).

Performance was so tempting, but usability-face-shot-gun was the greater evil.

I would look at sys admin type jobs at law firms, small medical practices and other places that need a “tech guy” but don’t need to hire a full time developer.
rkalla commented on Welcome to Hotel Elsevier: you can check-out any time you like – not   eiko-fried.com/welcome-to... · Posted by u/dredmorbius
SamBam · 3 years ago
It's amazing to me that the big research universities haven't banded together to make a competing open-access system of journals.

It would require no more work on the side of the academics -- they are already doing all the work for Elsevier -- and the administrative costs of hiring editors would almost certainly be equal to the fees they currently send to Elsevier.

The fact that they haven't makes me think that, with the exception of independent universities such as MIT, Elsevier's lobbyists are able to lean on the political people at the top of most large universities.

Your last sentence nailed it - they feed some of that money back into Uni so it's a win-win.

rkalla · 3 years ago
This won't be successful - ETSY is a publicly traded company, unless corrective action can replace the loss revenue from ads/punishing duplication/aliexpress - it's not going anywhere.

This is exactly what happened to eBay for anyone that remembers when it was garage-sale mania, then it became publicly traded and effectively became Target.com with < 1% of personal things sprinkled in.

No one messing with quarterly earnings.

Meta comment: I tried to click the link but since the title is so short and my mousing not very precise, I accidentally clicked the upvote arrow. I then clicked "unvote" and tried again, but the same thing happened. The third time round, I managed to click the link.

Takeaway: Very short titles might get you some upvotes from clumsy users :)

lol same and would have never thought to comment on it because obviously user-error, then I saw this and thought twice.
rkalla commented on I think US college education is nearer to collapsing than it appears   twitter.com/sama/status/1... · Posted by u/jger15

I think the writing on the wall is clear regarding student loans.

The entire notion of taxpayer funded student loans is a scam on both taxpayers and students. It’s a system that allows the colleges/universities to charge any tuition they want and guarantees there will be an artificial demand.

For about a decade at least 1M student loan holders default per year. Long before the defaults reached that high, everyone involved knew that student loans were far outpacing the economic value, and yet not a single college or university stepped up in goodfaith to blow the whistle, they continued to suckle at the tit to the detriment of their own students.

Education is supposed to benefit students and the nation as a whole but the ridiculousness of loans has ensured it ruins lives and at >$1.5T in taxpayer funded debt that continues to grow exponentially it is a detriment to the country.

Collapse of student loans will of course have an impact of the college/university landscape, but the industry as a whole will not collapse, rather tuition will “collapse”, or come down, to what students can actually afford out of pocket without going into debt. And if the universities/colleges somehow can’t survive on existing taxpayers subsidies from the Dept. of Educations $68B annual budget plus out of pocket tuition rates, then welcome to the real world your university/college is a failed business.

rkalla · 3 years ago
With the inflation we've seen in the last 24 months do you think the tuition will still come back to earth or just stay put for a decade or more?
