By my understanding fuel cells are less about form factor, and more about directly converting the fuel into electricity across a membrane, like how batteries operate, so like a battery that takes in Hydrogen on one terminal and Oxygen on the other, being more efficient than burning it in an engine and trying to recapture some of that as electricity after thermal and friction losses have eaten into it.

So it is more a replacement for the engine than it is for the fuel tank. Wikipedia

For the most part, it varies by material and state of matter, but assuming the chemical composition doesnt change and no material changes phase, then it is pretty close to linear in most materials.

This isnt even the only iron battery chemistry! The one in the article is Iron-air but you can also do Iron-Iron

Oh, didnt know that was posted, some of the tests seem to be different from last time, it hasnt regressed but hasnt improved much yet either (from the ones that were the same). It does seem to have pulled ahead of BTRFS since the last test, doubling score in the DBench test, but it still varies a lot compared to the other filesystems it seems, doing worse pretty regularly.

That’s fair, it has changed a bit since then and I’m hoping we get another filesystem benchmark to see if it has improved, and the caching features might offset that on frequently used data, but I don’t know how hard that would be to benchmark.

In my use it has been pretty stable so far with 7 disks participating (3 caching SSDs, 4 mechanical disks, with 3 copies of metadata and 2 of data), but I’m not using the more experimental features like erasure coding, I will note the on-disk-format has changed twice since it has been in the kernel, and it hasnt been there long, but it has succeeded both on-disk-format upgrades without obvious data loss, and it recently got self healing for some checksum errors, Id say its probably ready for use if the data is backed up, replaceable, or can be gone without (so for me games are all I have that fits this). Otherwise I would use caution if you use it, but I am very optimistic about the future of the FS, as Kent Overstreet (the creator) has taken a lot of care with it.

I use bcachefs for my games, I like that it lets me have multiple disks with redundant data copies, plus ssd caching of frequently accessed files, this fs is linux specific for now as far as I know, and is still experimental. I use ext4 for everything else, and FAT32 for flash drives.

I envision it like AT&T’s break-up, where the singular Google is broken up into regional companies that will (hopefully) have to compete with each other.

The US Army used to teach shooting similarly to that, minus the hand in the pocket of course.

Absolutely.

The metals are forming a Galvanic cell with the salt water as an electrolyte, the section of the linked article labeled Galvanic corrosion mentions the splitting off of hydrogen in salt water. There is no membrane so electricity just goes through the conductive salt water. The exact voltage depends on which two metals were involved, this page has a table of the voltages in sea water (in mV)

Buckwheat pillow, holds it’s shape well and you can flatten it out or bring it back together to adjust the thickness, big downside though you kind of have to mold your head into it when you go to bed, really just boils down to adjusting the thickness, laying on it, and rocking your head back and forth on it a couple times to shape it. They dont fold well but I feel they don’t need to.

One example I had with DDG image search was transparent electronics, I couldnt find a way to get electronics with a transparent case, DDG would only give me generic electronics images that had transparency. Google got it though

When (according to about:unloads) my average firefox tab is 70-230MB depending on what it is and how old the tab is (youtube tabs for example bloat up the longer they are open), a chat app using over 350 is a pretty big deal

just checked, my firefox is using 4.5gb of RAM, while telegram is using 2.3, while minimized to the system tray, granted Telegram doesnt use electron, but this is a trend across lots of programs and Electron is a big enough offender I avoid apps using it. When I get off shift I can launch discord and check it too, but it is usually bad enough I close it entirely when not in use

To be fair I think it is there as a backup for low temperature climates, the Lithium batteries wont charge at temps that low, but they still could have setup the lithium batteries as an emergency backup for all the 12v stuff.

Non-metric or non-decimal money is referring to systems where the multiple tiers of money, like our cents and dollars, are seperated by amounts other than 10 or 100, like the old British system of 12 pence in a shilling and 20 shillings in a pound https://en.wikipedia.org/wiki/£sd

to be fair, the documentation that came with products used to be alot better, Ive had plenty of “manuals” come with products now that just say how to start the device and follow a setup wizard.

In that case decimal is flawed too, 0.6667 or any such approxination doesnt exactly equal 2/3. It technically happens in any number system where you are dividing by a prime that isnt part of either the base or the number being divided

Yes but you cant have the alarm’s time synced from the phone, no alarm clock i know of lets a phone set the alarm.

But wouldn’t TRIM be the deleting he is requesting? Removing the charges would be setting all the bits in that block to the same value.
