what happens the day that justifiably enraged but unarmed students are attacked by the mindless thugs with guns, but massivly outnumber the thugs and fight back? is there a policy to retreat? or gun them.down. order at any cost! the question of who's order and in what context is off course, not up for discussion.

The title would be better if it mentioned Pakistan, cleptocracy, broken institutions,and war lords and how PV appears to be the pragmatic response. But my own experience, going off grid in Nova Scotia 15 years ago,is that at first people would ask how much it cost, and then often start a bitter diatribe against the power company, but now people are going ahead getting pannels and living as they see fit, the same institutions here now too busy and remote to enforce the regulations to (SAFTEY! SAFTEY!), disuade that. Solar PV is inreadably fault tollerant for basic DC current off grid battery charging, and people are jimmy jamming any and all old used batteries for storage.The sense of agency derived from having stuff power up from home built systems the first time is a powerfull motivator to keep going.

no matter how you feel about sex, it's impossible to fuck without it, so it will remain popular for the forseable future.

pull out the led, check its resistance, put a resistor/diode of the same resistance in it's place, and the continuity circuit will be happy. works on many many circuits, and if you are lazy or after another type of work.around, just put in a trim pot , which just might make a boost controller "think" it's on top of mount everist and provide a few more psi, or well several bar, whoooosh, wheeeeee

Pokeing the climate deniers in.the.eye.

There is a significant chance that "locked in" would be a best case scenario, as it suggests that we have a clue about what we have gotten our selves into. I have done my best to teach myself how to understand all of the factors effecting our planets climate, and have looked at the sattelite feeds since day 2, on the internet, and I can very definitly say that we are in completly uncharted territory that is well outside any of the worst case modeles or predictions.What that means for our weather is unknown.and debatable, but certainly warmer, and less comfortable for most. The real danger for us is connected with deep ocean warming, which while the physics is understood perfectly, there isn't enough data for a baseline and to monitor and predict changes.

it wont happen. fusion is a stellar phenominon that is powered , and contained by gravity, and sustained by a stellar mass. we have no plausible way to contain a fusion reaction over time periods that are monitisable, personaly, I do use fusion to power my house and shop, but keep the uncontained reactor 149600000 km from my power converters, but even at this distance electrical shielding and good grounds is the minimum to survive occasional power surges. And this last issue is not going away, there is NO plausible containment method that will survive the inevitable surges and variations that create ultra intense concentrations of energy that will exceed any "specification" The realy realy lucky part is that fusion will destroy the generator on loss of containment,and self extinguish, and all that gets vaporised, is money.

you dont even have to watch

just run the concept of snorting wasabi powder through your mind

which I have not seen, but sticks with me

I am very impressed with the, why wait? just do it now approach to the future. which while not here, IS there.

have radar transparent faceted dome/covers on the earth side, the faceting will reduce light reflectivity in any given direction

and yes there are plenty of radar transparent composites used in aviation and ship domes

Jellyfish, bieng transparent and without a brain, dont have any secrets, and instantainious wound healing might be the compensation for that, or price, but by all accounts they have managed to get by more or less as they are, for 700 million years and so will likely be availible for further observation, for as long as we manage to stick around.

Unfortunately, the headline, like ALL of the rest for decades, is woefully conservative and fails to address the real situation, and more probmilmaticaly the failure modes of intense climate change. The current (daily) charts and maps as all in record teritory, with changes so extream as to suggest that there could be unmanageable conditions in our imediate future.

edit: The charts shown in the article, show the institutional insanity, by greying out Ireland, speaking of "europe", but showing only data for England.

1- what night sky? do you mean the one that is so bright from electric lighting that the seagulls are now flying a night shift? 2- one of the taboo subjects is solar phenominon and what happens if everything in orbit looses guidance due to a local stellar event? do we get a ring? or lots of meteors

open a window, wait, ok, ok, turn up the , wait, no, ummm, hmmmmm re, re, no forget that, hmmm anyway, as a person with a strong interest in civil engineering, systems, and the subset of air handling, I can say that there has long been disenting arguments about how things are built,that have been ignored due to cost, which are large in terms of internal volumes required, and the intractable issues around, noise, filtration, heating/cooling and maintenance. And as the climate warms, and in many areas pollution increases , the inadequate methods used to "calculate" requirements, get further from real world needs. You could try throwing a desk through a window, but as that is one of the things the planners and engineers have antisipated, it will prove to be surprisingly difficult.

As one US president quiped, all men are equal, before fish. Though all men are created un equal, idivualality is one of the non negotiable absolutes in our universe, like it or lump it.

the thing is that for a long time the web was horrible wonderfull awfull awsome terrible addictive and almost all encompasing, and now blessedly, reality is looking like a great place to be, and is. And since there is absolutly no way that the human effort of building the web will ever happen again, and whatever it is that is going online now is beyond exhausting and pointless, and reality remains real along with all the humans in it, the tendency will be towards enjoying the ultra high informational density, low latency and cost of reality VS sad AI slop

now I understand why it's called a "fine", because it's way more than ok, it's just fine indeed.

sheeesh , measly 24-bit/192kHz of course it makes no sense, unless it is downloaded through low oxyegen wire, which somehow and unfathomably, must have been omited or forgotten.
