May have been a good post, but in the wrong thread. :D

All good points. And I haven’t played with a multitude of sensors. The only cooled sensor I will have anytime soon is my uncooled sensor + liquid gas evaporating.

Something I’ve wondered about is maybe using these MIR LED’s that have come out to see if you can get the wratten filter to pop, then use a laser system to saturate the detector. Its not clear to me that you can effectively camouflage when its a multiband sensing system. But maybe you can find the detectors and blast them with enough light they can’t see shit.

Coincidentally, as another experiment, I tried a fast flavour of thermite to get solar protection triggered on my camera (if solar protection is triggered, this particular product goes into shutdown). Sadly, I could not trigger it. With more than a matchbox full of thermite, maybe I would, but at an impractically close distance. I did however achieve my solar charging controller turning on, and starting to charge batteries off the light produced from thermite. Not for very long, about 5 seconds. :)

Lasers of an appropriate wavelength, generally speaking, should work. A laser within the transmittance curve of germanium would get into a thermal camera with fairly good certainty. But lasers cost so much that an interceptor drone with a net gun is likely cheaper. :)

In a military context, if one wants soft defense, one might point a microwave beam at the drone to mess with its onboard electronics, but this also requires ridiculous amounts of power (at least several kilowatts) and has limited range, and in a civilian context, there may not be adequate warning of a drone being present, unless one also carries a thermal camera (then it shines like star).

As long as a car isn’t open source, a car maker going out of business is a big problem. It’s going to leave customers stranded without spare parts.

That, in my opinion, fully explains the propping up.

And for this reason, I predict that they will be keeping even unprofitable manufacturers on life support despite everything, quite long. The companies will likely get merged and production of spares will hopefully be arranged. If not, lots of people will be angry.

Good point. If it’s a drone, the observer is in the upper hemisphere. Covering the entire upper hemisphere is unpractical, but covering a good portion of it can be done.

Then comes a dilemma: people emit considerably both with their head and face, and with their feet.

Covering the head will expose the feet, so maybe ghillie trousers to complement the umbrella? :D

I’m not qualified to criticize, confirm correctness or deny correctness (not a climate person), but in short, if the article is correct, we’ll know a bit in advance when it’s going to happen…

…and it’s likely going to happen soon enough for many of us to see (likelihood of happening in decades, not centuries).

Thank you. :)

I was not aware of this tool existing, and cell site metainfo being reasonably accessible. I will definitely try to set up a kit, give feedback to the authors of the tool about what it saw, and then use it for my own experiments. :)

What puzzles me: what is the risk of wind lull at high altitude? I know that winds are terrifically fast there (100 km/h would be considered a slow day at 10 km altitude) and slow down approaching the surface, but do lulls exist at all?

Yep.

5000 m2 is more or less “the size of a football field” (50 x 100 m).

5 km2 is 5000 x 1000 m = 5 000 000 m2, “the size of a large farm field”, not a practical size to get airborne with current technology.

It definitely has. But in my case, I’m not bypassing it - the external part of the charger is communicating to the car using the Type 1 interface and telling “charge at X amps”. (But I know that’s not applicable to DIY situations.)

…and since the tripping occurs within the ramp-up period or very soon after (e.g. on second 7), I’m fairly certain nothing has managed to overheat yet. I think that some generators have poor steering regulators, mine included.

Then take one that can take about 80% of the generator power and feed that into the battery bank. Size the charger to the lower of both numbers.

80% feels like too much.

My electric car has a 1600 W charging mode. My emergency gasoline generator supplies 2100 W theoretically if the power factor is 1 (totally resistive load). When I connect my charger in 1600 W mode, the generator trips and drops the load, however. It manages to work at 1200 W or below. And this happens despite the charger having a slow ramp-up behaviour (it doesn’t go to full load in a second, but during 5 seconds).

So based on experience, I would advise to pick a charger that can take 50…60% of the generator’s power.

For a 24V lead acid battery, look for chargers designed for warehouse equipment (forklifts), wheelchairs, truck batteries and such.

Eventually, you do need to.

My electric car (from 2014) has other stupid features, but at least, no electric parking brake. Rear pads were obviously very thin by now, and most likely the previous owner also changed them once. So I went to a self-service workshop last spring, brought along spare parts from a shop across the road, replaced them.

Annoying part: drums came off relatively poorly, the new pad set needed treatment with a disc grinder (allegedly compatible part, but a tiny bit of metal was 2 mm too long).

When the time comes and my factory made car wears down, I intend to build another DIY e-car, as I’ve done twice before.

the able bodied revolutionary

This passage suggests an assumption - that anarchist society is reached through a revolution that requires forceful action. Or maybe war. But, I must note - even in disputes that were settled with artillery, not all revolutionaries were able bodied.

However, if the previous assumption is true, the subsequent conclusion is indeed true. In a war, you can’t depend on reliable supplies of medicine, fuel, electricity or even food and drinking water. A factory or warehouse may get bombed. A power plant may get bombed. A water treatment plant may get bombed.

Then again, I must remaind: states are quite and very capable of waging war, without any anarchist assistance. Yet people dare to live in states, despite risk that a local state will go crazy and attack others, or the risk that a foreign state will invade.

“We don’t exactly have alternatives, Sherlock”, one would surely counter. And indeed, most of Earth is owned by some state or another, except Antarctica. Lucky people can pick the flavour and intensity of statism they live under. Less fortunate ones dont’ get a meaningful choice.

And indeed, a lot of people on Earth right know… would not have the option of getting insulin - despite living under a full blown hierarchy - not to mention accessing a tailor-made cancer vaccine (most of us on Lemmy don’t have that option either).

What would anarchism change?

Well, for a start, it might be permissible to cook it up at home. Speaking as an ex-biologist: you need a bioreactor and purification process or animal organs and a purification process to get insulin. Once you start making it, there’s no point making it for one patient only. There’s no point in making antibiotics for one patient only. There’s no point in making vaccines for one patient only.

So you industrialize and standardize the process. And I don’t see anything in anarchist ideology saying “no, you shall not industrialize any process or announce a standard”. I see critique of how resources are managed. Anarchism criticizes hierarchies of power (wealth == power). It does not typically critique medical or technical advancement, unless some form of advancement alienates people from their rights or concentrates power. Anarchism does criticize large organizations, but only a few tendencies of anarchism conclude that large organizations may not exist. Sometimes they’re needed. Risks that they bring can be grounded in various ways.

…but getting back to the beginning, I think one should try to reach anarchy without war. War very much necessitates acting like a state to maximize chances of victory. It shouldn’t be the first option for an anarchist, and might actually be a the last option to try (when a choice has been forced and nothing peaceful has worked).

From a personal perspective…

In that kind of scenario, I just…die.

Emigrating from a place where violent conflict looks to be imminent, would be advisable if once needs advanced medical care.

I would likely try the methods of car headlight repair:

• fine sandpaper (e.g. 600)
• followed by ultra fine sandpaper (e.g. 1000)
• followed by polishing sandpaper (e.g. 2000 or even more)
• followed by polishing paste (e.g. cerium oxide) on a felt pad

However, since I see that the sink has a glossy surface… I would be deterred by that. The method I mention may reach a layer which isn’t burnt, but will wear off glossy finish and there’s no certainty of it returning in the same tone after polishing is done.

What paint to use - sorry, no idea.

This looks like it could credibly improve both safety, cost and ecological footprint. Nice. :)

(I was previously aware of peat-derived materials being used in batteries, but lignin seems to fit considerably better since wood grows back a hundred times quicker than a peat bog.)

My interpretation:

• Netanyahu has already secured political control of Shin Bet (secret police) by swapping its director
• he wants full control of the IDF, but some people haven’t been willing to swear personal loyalty
• most likely, the general advocate was one
• those people are now removed, one by one, with various methods

As a result, the culture of impunity can continue.

The general advocate who was jailed - she was the person who received, among other documents (likely thousands of documents), the recommendations of the IDF internal investigators about the Rafah ambulance massacre (killing of 15 paramedics and destruction of 5 vehicles).

The IDF recommended to do nothing, claiming that they did nothing particularly wrong, just made some mistakes (executed 15 unarmed medics, some at close range with their hands bound, and tried to conceal the deed).

I don’t know what she would have done, but my reading of the background and signals suggests she might have recommended criminal charges. That would have made her removal absolutely vital for the Netanyahu regime.

A note about ability to use “world@lemmy.world” - today it didn’t load at all. I let the tab wait for something like 10 minutes. It stayed like that.

Then I refreshed / reloaded the tab. And behold - it loaded.

I subsequently found a thread I wanted to comment about. Upon posting there, to my surprise, I received the error message “Lemmy is currently starting”. Upon a repeat attempt, posting also worked.

I don’t know enough about Lemmy internals to make sense of it, but wanted to write down the experience.

Makes it quite clear: sea is responding with a delay, but it will respond, and then very likely - for a long while, it won’t stop responding even if the driving force is removed.

it doesn’t really say how much power you can get out of it, but it sounds interesting!

Not much. The manual says you can run one LED off 5 mud cells. That would imply about 3 volts and maybe 10 milliamps. Enough to show that there’s a gradient of potential, not enough to accomplish much of anything. :)

…and some return, too.

Ukraine is notable in one way: it does not draw up people under 25 years for war (so far). It trains them, it lets them volunteer, it welcomes if they build technology for war, but it doesn’t order them to go.

What the reasons are, I’m not totally sure, but I think the government and Rada might want to avoid creating a “lost generation” where many experienced wounds or trauma in youth. The generation they are attempting to spare is a weak spot in Ukraine’s population pyramid - relatively few people were born between 1999 and 2004. If that generation has considerably less kids than generations before them, there will be a pretty bad population decline coming.

Of course, some fear that under pressure, government might cave in and start sending increasingly young people to fight. Others meanwhile fear that many will move abroad and never return.

I’m not sure what to think about it. But I’m pretty sure a person just out of school isn’t the best candidate for war. Physical fitness is less important today, but psychological stability under pressure is required.
