Nicolas Cage film 'The Surfer' induces knee-buckling six minute standing ovation at Cannes ( beachgrit.com )

Nope! And most hydrogen is fossil fuel (methane) derived and horribly energy inefficient. At this point it's green washing at best.

Edit: adding data:
Steam-Methane Reforming (SMR) accounts for about 95% of all hydrogen production on earth. It uses a huge amount of heat, water, and methane to produce hydrogen.

https://en.m.wikipedia.org/wiki/File:SMR%2BWGS-1.png

For inputs:

  • 6.2MWh of Heat
  • 2.2 tons of Methane
  • 4.9 tons of pure water

The outputs are:

  • 6 tons of CO2
  • 1.1 tons of H2

The overall energy in vs energy out is at most 85% efficient. https://www.sciencedirect.com/science/article/abs/pii/S0016236122001867

Hydrolysis, the main competing method, and the one most touted by hydrogen backers, accounts for about 4% of hydrogen production.
This method takes in only pure water and electricity, but it's efficiency is abysmal at some 52%. In every case, a modern kinetic, thermal, or chemical battery will exceed this efficiency.

Other methods are being looked into, but it's thermodynamically impossible for the resulting H2 to produce more energy than it takes to create the H2. So at best today we could use H2 as a crappy battery, one that takes a lot of methane to create.

When it's a documented scientific process and it's scaled up and used in the real world to displace the other methods, I'll be ready to acknowledge hydrogen as a valid part of energy infrastructure.

Which RSS aggregator do you use? I cannot seem to find one that works for me.

I cannot stand google news any more, too much spam, clickbait and advertisement. So I decided to try to selfhost an RSS aggregator to make myself a news feed that I would be comfortable with. Being RSS such an "ancient" thing I thought there will be many mature systems, but I'm not sure that's the case.....

Never ask a man his pay, a woman her weight, or a data horder the contents of their stash.

Jk. Mostly.

I have a similar-ish set up to @Davel23 , I have a couple of cool use cases.

  • I seed the last 5 arch and opensuse (a few different flavors) ISOs at all times
  • I run an ArchiveBot for archive.org
  • I scan nontrivial mail (the paper kind) and store it in docspell for later OCR searches, tax purposes etc.
  • I help keep Sci-Hub healthy
  • I host several services for de-googling, including Nextcloud, Blocky, Immich, and Searxng
  • I run Navidrome, that has mostly (and hopefully will soon completely) replace Spotify for my family.
  • I run Plex (hoping to move to Jellyfin sometime, but there's inertial resistance to that) that has completely replaced Disney streaming, Netflix streaming, etc for me and my extended family.
  • I host backups for my family and close friends with an S3 and WebDAV backup target

I run 4x14TB, 2x8TB, 2x4TB, all from serverpartsdeals, in a ZFS RAID10 with two 1TB cache dives, so half of the spinning rust usable at ~35TB, and right now I'm at 62% utilization. I usually expand at about 85%

Yeah exactly. Toy OSs have only increased in scope, scale, and number. And the public is still completely unaware, because these toy OSs don't solve day to day problems the way that Windows, Mac, and Linux did when they first came to market.

Kata1yst ,
@Kata1yst@kbin.social avatar

Disingenuous how? You don't think Linux solved a real day to day need of it's first users?

Sure, from Torvald's perspective, it was a project specifically to solve a small problem he had. He wanted to develop for a nix platform, but Minix wouldn't work on his hardware, and the other *Nixs were out of reach.

And this was generally true in the market as well. Linux arrived just in time and was "good enough" to address a real gap, where Minix was limited in scope to basically just education, Hurd was in political development hell, and the other Nixs were targeted at massive servers and mainframes. Linux filled the "*Nix for the rest of us, inexpensively" niche, eventually growing in scope to displace its predecessors, despite their decades of additional professionalism and maturity.

That niche is now filled, the gap no longer exists. A "New Linux" wouldn't displace Linux, because the original already suits the needs we have well enough. This is precisely why the BSDs and Solaris were "too little, too late". They were in many ways better than Linux, but the problems they solve compared to Linux are tiny and highly debatable. Linux addressed a huge, day to day need of people who were motivated to help.

The stem cells themselves are self-repairing and self replicating. Quoting Wikipedia:

Due to the self-renewal capacity of stem cells, a stem cell line can be cultured in vitro indefinitely.

Currently all embryonic stem cell research and therapies in the US are conducted using only 486 cultures.

Author doesn't seem to understand that executives everywhere are full of bullshit and marketing and journalism everywhere is perversely incentivized to inflate claims.

But that doesn't mean the technology behind that executive, marketing, and journalism isn't game changing.

Full disclosure, I'm both well informed and undoubtedly biased as someone in the industry, but I'll share my perspective. Also, I'll use AI here the way the author does, to represent the cutting edge of Machine Learning, Generative Self-Reenforcement Learning Algorithms, and Large Language Models. Yes, AI is a marketing catch-all. But most people better understand what "AI" means, so I'll use it.

AI is capable of revolutionizing important niches in nearly every industry. This isn't really in question. There have been dozens of scientific papers and case studies proving this in healthcare, fraud prevention, physics, mathematics, and many many more.

The problem right now is one of transparency, maturity, and economics.

The biggest companies are either notoriously tight-lipped about anything they think might give them a market advantage, or notoriously slow to adopt new technologies. We know AI has been deeply integrated in the Google Search stack and in other core lines of business, for example. But with pressure to resell this AI investment to their customers via the Gemini offering, we're very unlikely to see them publicly examine ROI anytime soon. The same story is playing out at nearly every company with the technical chops and cash to invest.

As far as maturity, AI is growing by astronomical leaps each year, as mathematicians and computer scientists discover better ways to do even the simplest steps in an AI. Hell, the groundbreaking papers that are literally the cornerstone of every single commercial AI right now are "Attention is All You Need" (2017) and
"Retrieval-Augmented Generation for Knowledge -Intensive NLP Tasks" (2020). Moving from a scientific paper to production generally takes more than a decade in most industries. The fact that we're publishing new techniques today and pushing to prod a scant few months later should give you an idea of the breakneck speed the industry is going at right now.

And finally, economically, building, training, and running a new AI oriented towards either specific or general tasks is horrendously expensive. One of the biggest breakthroughs we've had with AI is realizing the accuracy plateau we hit in the early 2000s was largely limited by data scale and quality. Fixing these issues at a scale large enough to make a useful model uses insane amounts of hardware and energy, and if you find a better way to do things next week, you have to start all over. Further, you need specialized programmers, mathematicians, and operations folks to build and run the code.
Long story short, start-ups are struggling to come to market with AI outside of basic applications, and of course cut-throat silicon valley does it's thing and most of these companies are either priced out, acquired, or otherwise forced out of business before bringing something to the general market.

Call the tech industry out for the slime is generally is, but the AI technology itself is extremely promising.

That's the neat part of the speed of light. It's the speed of light for every reference frame, no matter who is looking at you or from where.

Kata1yst ,
@Kata1yst@kbin.social avatar

To actually reach the speed of light you'd be massless, so the only damage, would be from momentum transfer, at which point your particles would be reflected or absorbed like light.

But that aside, mostly I was referring to your statement:

'Speed of Light' compared to what?

Which is really not a concern. It's the speed of light for everyone with respect to everything, or it isn't the speed of light. Like, two beams of light going in opposite directions don't see the other light beam going at 2x the speed of light, just at the speed of light with lots of time dialation.

ZFS is a very robust choice for a NAS. Many people, myself included, as well as hundreds of businesses across the globe, have used ZFS at scale for over a decade.

Attack the problem. Check your system logs, htop, zpool status.

When was the last time you ran a zpool scrub? Is there a scrub, or other zfs operation in progress? How many snapshots do you have? How much RAM vs disk space? Are you using ZFS deduplication? Compression?

Has anyone here built a Beowulf Cluster? ( spinoff.nasa.gov )

Development is happening in the dev's branches. Branches are generally kept local until submitted for a PR. You can easily see this in the origin branches and open PRs.

Honestly I'm not sure if you're trolling, don't understand git development, or if you really think that a project needs to iterate main multiple times per month to be your definition of "healthy open source", but I'm tired of shooting down such lazy attacks and won't be responding further.

Have a nice day.
