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.

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.

For inputs:
The outputs are:
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.
Yes, this in particular is something they need to bring the hammer down on now before others see this as a valid strategy. After the first 10s penalty he was out of the points and obviously consciously decided that if he was out any way, more penalities wouldn’t sting as much as his team bringing home another zero point weekend.
It was egregious and unsportsmanlike. And I say this as someone who generally likes KMag.
I use FreshRSS. Can’t say I love the interface, but with the open and standardized API, there are dozens of beautiful front ends to choose on any device.
For real? Damn it that’s going to be painful.
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%
My favorite city builder in decades. A few notes.
Pros:
Cons:
All in all, I highly recommend it, especially at the modest asking price. If you love city builders, charming and beautiful art, thematic settings, dynamic challenge, and solution engineering, this is a fantastic game for you.
Other games I’ve enjoyed that scratch similar itches:
Get it and have fun is my recommendation.
Seriously. This guy thinks that regulators would have stepped in to stop OpenAI or Microsoft from acquiring a no-name 2 year old startup with two rounds of funding?
Please.
Apparently that wasn’t one of his MBOs, so we can infer the board is a bunch of dumbasses.
Tbf, Russia has been sourcing ammunition from North Korea.
Yeah honestly no idea regarding moderation. But the codebase is maintained by a team.
There is a team, not a sole dev.
I’m not saying everything is roses and rainbows, but this is FUD messaging being spread openly by the mbin dev team.
Honestly, I bought my kid a used Chromebook. No regrets. Lots of benefits.
This is kind of like saying grass gets wet when it rains.
Their products are getting purchased much faster, both for use and for stockpile. Of course it’s profitable?
Lol… But why would it? There’s only 3 of these things and they’ve only launched 7 missions. They’re also only 29 feet long. And are payload hogs on their launch vehicles.
It’s about 500 times easier to just piggy back 20 micro-sats on the next atlas or falcon.
The whole “x37 is a spy program” was literally started by speculation in an opinion piece with zero evidence. It being a visible and public program mean it’s absolutely almost certainly not an active spy program. Especially combined with it’s mission profiles.
To be clear, it’s probably not a spy vehicle. It is probably testing technologies for use in spy vehicles.
I’ve had great experiences with exactly one vendor of second hand disks.
Currently running 8x14TB in a striped & mirrored zpool.
Really all I do is setup fail2ban on my very few external services, and then put all other access behind wireguard.
Logs are clean, I’m happy.
Yeah, you should be scrubbing weekly or monthly, depending on how often you are using the data. Scrub basically touches each file and checks the checksums and fixes any errors it finds proactively. Basically preventative maintenance.
https://manpages.ubuntu.com/manpages/jammy/man8/zpool-scrub.8.html
Set that up in a cron job and check zpool status periodically.
No dedup is good. LZ4 compression is good. RAM to disk ratio is generous.
Check your disk’s sector size and vdev ashift. On modern multi-TB HDDs you generally have a block size of 4k and want ashift=12. This being set improperly can lead to massive write amplification which will hurt throughput.
https://www.high-availability.com/docs/ZFS-Tuning-Guide/
How about snapshots? Do you have a bunch of old ones? I highly recommend setting up a snapshot manager to prune snapshots to just a working set (monthly keep 1-2, weekly keep 4, daily keep 6 etc) https://github.com/jimsalterjrs/sanoid
And to parrot another insightful comment, I also recommend checking the disk health with SMART tests. In ZFS as a drive begins to fail the pool will get much slower as it constantly repairs the errors.
And why they dismantle the systems they’re tasked with protecting the moment they can.
