The money quote:

«Because the system-size plasmoid is an Alfvenic outflow from the reconnection site, its thrust is proportional to the square of the magnetic field strength and does not ideally depend on the mass of the ion species of the plasma.»

[Edit: a bit more detail] The exhaust velocities are 20 to 500 km/s, the plasma is relatively low-temperature and density, the exhaust speed depends on the magnetic field (B^2). A device a couple meters long is predicted to produce thrust up to 100N with 10MW of electric power. All this with lightweight ions to conserve both energy and mass. (To compare, current best ion drives produce exhaust at 20-50 km/s only with heavy ions, with thrust well below 1N.)

If this works, this is a big deal. Even if it does not completely remove the tyranny of the rocket equation, it may greatly alleviate its influence. It might allow to quickly move around the Solar system using moderate amounts of reaction mass, provided that a powerful enough nuclear electric plant can fit on board.

This of course isn't going to work for liftoff from Earth or Mars, but alternative mass orbital transit solutions exist at least in theory (space elevator), while there were no alternatives for proper space travel.
I've read through some of these listings, it's legit.
Nothing in the report justifies the claim made in the title.
Maybe, or what if it’s exactly what the DoD is saying? That there’s verified advanced UAPs beyond our current technological understanding.
There's probably barely even 1000 hours on all of youtube of FSD Beta 9.0. It looks like these clips are actually from just 3 videos which in total are less than 1 hour of video.
There’s a big gulf between “we’re using a common technique that’s regularly used in engines, even though it’s not OEM spec for this specific area” and “we’ve disabled an emergency safety system because it’s not working right”. Trying to equate the two is very disingenuous.
The ESP32 is vastly more powerful than the ESP8266. Dual core, each core is more powerful, it has BLE, more RAM, flash, GPIO - as well as a handful of other useful peripherals (RMT, PWM etc).

Now, the TinyPICO is more expensive than some ESP32 boards but that's because it's been engineered well and is manufactured in Australia by a maker that goes out of his way to support his products.
> Well Casios are better than TI calculators.

For scientific calculators, I would agree. For graphing calculators they might be better on technical merit or cost, but everyone is going to write programs for the TI so you might as well get that one.
Yeah some people can't think outside the box though. Probably not worth arguing with them. Nothing short of a Tesla engineering team coming out to inspect it will they be happy.
Yeah, I'm going to go out on a limb and guess that he doesn't have the power to do this. You're going to need a court decision to ban them. Presidents do not get to re-write contract law by executive order.

Note well: IANAL.
Thanks @adbachman, I’ve been looking at similar items like this for a home automation project that doesn’t rely on Google or Amazin
Why do you believe the system is likely to double your accident rate?

Statistically autopilot gets in fewer accidents than the average human driver. And if you believe you are an above average driver, why do you believe you would be unable to intervene if needed?
Decentralized computation
I was under the impression that the cost in insuring Teslas was down to the slow repair times, since insurance companies were often on the hook for rental cars while parts are on back order.
Yes it was thru Apple. Apple just blindly takes the side of whoever complains. Similar to YouTube/Amazon I guess. I'm willing to fight this, but hope a manual review will resolve matters.
In addition to the regular ESP32 benefits (BT, BTLE, dual core, etc), the TinyPICO is REALLY small and has really good power consumption in deep sleep mode. A lot of the random Aliexpress boards have power consumption on the order of 10-100 milliamps in deep sleep. The TinyPico is more like 20 microamps. Part of that is through higher quality parts (presumably better voltage regulator, battery controller, etc.). Part of that is through a more thoughtful design (instead of having to desolder an annoying always-on LED to reduce power consumption, you can just turn it off in code).
Businesses and charities already have a business license number. I am opposed to adding an additional license for something like this. If they use the existing number I wouldn't have an issue, but it sounded like there was an additional license that was required.
I really don't understand why Casio keeps changing the entire design of their calculators, though.
The article seems to imply that Tesla can very well fix this issue, but they don't train & equip their service centers to maintain the battery.

When the lease is turned in, it will just have to go back to the factory. Destination/freight charges on a car are often about $1200, and this was otherwise a simple fix.

If Tesla feels the need to charge the customer for using a 3rd party repair service that recreated a stronger version of the original fittings then the current owner will still have saved about $14,000, AND all of.your concerns will have been addressed.
Worth noting that the Pharma industry, as well as Big Tech and Wall Street, supported Biden. As a Biden supporter I’d like to believe that this is because he’s an old school Democrat and not afraid of biting the hand that feeds him. More cynically, this could be seen as posturing to keep together what is a very weird coalition (Occupy Wall Street and Wall Street under the same tent).

Also maybe relevant: https://ksr.hkspublications.org/2021/05/18/can-conservatism-...

> The best answer, in my view, is that the Republican Party’s remaining connection to the dominant sectors of the American economy occurs through its usefulness as a tool to selectively balance and discipline the members of the Democratic coalition. Big Pharma, for instance, will throw money at the Heritage Foundation to rant against “socialized medicine” whenever talk of the government negotiating drug prices surfaces, but pharma is hardly interested in repealing Obamacare, much less dismantling Medicare. Financial lobbies will rent the Republican Party to ward off troublesome regulations or taxes, but are hardly interested in “sound money” policies or big spending cuts that would derail financial markets, never mind social conservatism. Big Tech will team up with Americans for Prosperity to oppose legislation limiting app store developer fees, all while more aggressively controlling conservative speech online, and so on.
Cool.

May we please add term/age limitis for people in congress/supreme court...

Oh and lets ban insider trading protections for those in congress? Good Idea.

Maybe we should be much more transparent with wealth growth in congress and the government at large, especially when it comes to light that the guy who was supposed to achieve peace in the middle east and his wife made $650 million whilst serving in whatever capacity that was - and the fact that another offspring was allegedly paid $00 million from the chinese, or some $80 million from the russians, depending on who one would like to believe...

So lets take some steps at the top level.

e.g. J. Kerry "flew to russia today for a short visit to discuss climate change"

On a private jet, with an entourage, and likely security...

This motherfucker ever hear of a zoom meeting? Surely, he would have preferred all kids to zoom to school with masks on whilst talking to a webcam... so why did he have to "fly to russia to discuss climate change"?
Just be aware that PyCom chose to fork the MIT-licensed MicroPython and re-licensed it with GPL.

As a MicroPython contributor I can't/won't use PyCom's fork because any code I develop for it cannot be accepted upstream.

I do like their hardware, it's a shame they chose to make their software licensing incompatible.
Funny, I found Asia (and especially Japan) to be the polar opposite. Japan in the winter is a place where everywhere you go is too warm.
Plastics pollution and fishing.
Mini-LED is actually backlight technology building on top ( or more precisely "under" ) the same LCD display panel.

Micro LED isn't LCD at all. Its LED is the pixel ( or more precisely sub-pixel ) itself.

The problem is as you can imagine, how to built 8M ( 4K Resolution ) pixel / MicroLED at mass scale, and more importantly at a cost that is somewhat competitive or palatable for consumers. Both Mini-LED and OLED have a very decent roadmap in quality and cost reduction over the next five years. And as much as I want MicroLED display, there is nothing that shows similar promise. We might end up with another case of good being the enemy of best.
my reply will probably be downvoted, still: some fourty years ago we were all very worried about nuclear war, so scientist warned about nuclear winter, now there is a lot of debate on this [1]. Today we are worried about climate change, and now evidence was found that a similar event caused severe changes in the past. Is there a correlation here?

[1] https://en.wikipedia.org/wiki/Nuclear_winter#Criticism_and_d...
Of all the problem of OLED they didn't mention PWM.
I don't they said "there are uaps beyond..." , they said they couldn't explain all of them, that's all.
They should also have to state how much the repair would cost if done at the factory where they can actually service the battery pack.

Imagine if other cars were like that: "Sorry, we're not able to service engines so instead of replacing your timing belt for $400 you have to buy a new engine for $6000"

130k is a good non-FAANG offer for typical developer roles, as far as I’m aware.

100% agree. It takes more effort for me to write things out and learning a language with repetitive writing works for me so much better.
It's not (nearly!) the same but if you're interested in audio applications it's worth noting that I2S support was added to MicroPython recently - and will work on the TinyPICO.

Indeed, the standard even says one of the possible effects of UB is "behaving during translation or program execution in a documented manner characteristic of the environment" and I feel that was really the original intent.
Why US troops wear ceramic plates instead of just kevlar
The complaint wasn't color. Take laravel circa 2012 or so. All errors were expressed as like 80k of minified HTML so if you got an error in a unit test you better have a browser nearby to see it.

Some other systems will try to be helpful and traverse the object and display it on the screen. I've seen some that don't understand self linking datastructures and just give you a stack exhaustion whenever dealing with an error involving one because they try to infinitely recurse. Others, trying to "fix" this problem that's been easily fixable since the 60s with pretty simple algorithms, will instead only show a depth of maybe 2 or 3 levels and then you need to do a bunch of tricks to get a useful object

Other will not give thread information so you just get mystery errors without any way to attribute them.

Others will race condition the log and give you a confusing mess of partial data mashed together.

And yet others will just fall back to some generic "an error occurred" with no further information whatsoever. Still others will think you have no interest in strings over some random amount divisible by ten, say 50 characters long and just truncate them with no way around it.

And some you are expecting a longjump or a trap or an interrupt but instead it gets intercepted for the pretty logging and thus your tooling didn't see it and the faults go undetected

Then there's the ones that don't respect the call stack limit you gave the command line or the verbosity setting or things like polluting the call stack with layers of the error handlers.

There's one where the default logger synced on write so if the system crashed I'd get the last message, but the fancy logger didn't so I'd just get a bunch of corruption. It was just great!

They're generally speaking terribly done and I routinely have to disable them. It's just a clown car.

You probably have only worked on gifted perfect projects by flawless programmers, and I congratulate you!

I've dealt with mostly confused incompetent people who think they are really clever and just destroy things
I wish there was actual software support for Acq/Release-like semantics, but somewhat more relaxed by way of e.g. specifying two stores (data and pointer-to-date) to require in-order visibility, without enforcing a strong ordering of this store pair relative to other (semantically unrelated) stores.

Barrier-based abstractions could handle that, if they support more than one barrier. For loads, this would allow efficient dependent load reordering, by essentially enforcing the ordering only where needed for concurrency reasons (this mostly helps speculating loads before the address is confirmed, and not needing to snoop for invalidations of the cache line that contains the speculated address/killing the load), and similarly taking pressure of the store buffer by being less strict about the order in which it commits to L1D$.

RISC-V's propose WMM has such weak default ordering, but due to using fences, it's overly strict to the point where it performs worse on heavy concurrent code that's littered with atomics, compared to a TSO version (of the same softcore) that "just" prefetches exclusive access for writes. Even when turning RMW into relaxed semantics, so it's just due to the overly-strict load fence that effectively trashes all shared-state L1D cachelines.
Wouldn't space-faring civilizations be more likely to exist along the galactic plane, which we have a much harder time examining?
You're allowed to bring a leased car to any mechanic for repairs. You don't have to use the dealership, or even OEM parts if others are available. Or at least every lease agreement I've ever read-- and I always read the whole thing-- has never limited this. I'm in the US though, things may differ elsewhere.

Also the correct word it moot, not mute. And neither apply in this situation, so the issue of mute is completely moot.

We recently started publishing our legal stuff for Seam: https://getseam.com/legal

The TL;DR, I had an excellent attorney friend (who, cherry on the quake, has a CS degree and understands APIs very well) write all of it for us. All in all, it was sub $5K and I had some very specific wording/requirements around privacy which took a lot of work. I think a regular law-firm would have charged 10X this, maybe more.

If your product is simple (Saas), a cheap attorney should be able to loosely model something that works based on other example companies out there. Maybe have a more experience counsel also take a second look ("second opinion").
Why not all three? The latter two are particularly aggravating when they come together.
> Much lower pressure, actually - domestic water is supplied closer to 50-60psi.

Cries in England where domestic water can be as low as 10 psi and sometimes won't even reach the top of your house and you have to go downstairs to get water...
You were told "nobody will want that" by people who wouldn't want it to exist as it flies in the face of those walled gardens. I know plenty of people that want that now for sure, myself included. People are tired of their data being "owned" by these companies and subsequently having it lost or stolen. Something like this would be like mixing bitdefender box and a NAS with HumHub or some other open source social network software maybe?
So number [2] does not reference the same time period the
referenced time period in your article is 1/2 the concentrations from 250-300m years ago. There is no disputing the numbers from 200-300m years ago as far as I can tell. [4] is the same graph I looked at. [3] Is not something I even tried to suggest. [5] is obvious and well known in this area of research. I asked a couple specific questions only response [1] addresses them partially. I'm not saying the planet isn't getting hotter by any means. I was asking if I had the periods/eras correct and the CO2 levels so I could appropriately create a frame of reference.

The poem reminds me of the Coen Brothers movie "Ballad of Buster Scruggs", released on Netflix a few years ago, which presents four (or five) vignettes.

In one of these Harry Melling plays a handicapped performer of poems in the "wild west", and the segment starts with him reciting this poem. Liam Neeson plays his manager. The segment is one of the most Darwinian, cold things I've ever seen. The whole movie is great, but this vignette especially.

EDIT: the beginning of the segment: https://www.youtube.com/watch?v=GdQKUvv3bew

If FTL is possible (and engineerable) then the Fermi paradox becomes a serious problem. There "should" be aliens all over the place unless...

(1) We are wrong about the nature of the universe and strong theism / creationism or the simulation hypothesis (which is the same thing more or less) are right.

(2) Life or complex life are so phenomenally unlikely that we are literally the only example in the local galactic supercluster at least, if not the whole universe. Speaking of creationists they often argue that the probability of life forming from non-life is insanely low. Maybe they're right about those probabilities and it only happened once.

(3) We live in a cosmic cemetery. There is a big nasty great filter ahead of us, and nobody has passed so far. Maybe the great filter is when you try to actually build FTL and cause a space-time catastrophe.

(4) We live in a "dark forest" and should be very, very quiet. Shhhhh....

(5) We live in a nature preserve. See #6.

(6) Last but not least, at least some UFOs really are ETs in which case there is no Fermi paradox. They're here and we have seen them. They're just laying low and not making overt contact.

My money would be on 6. If we demonstrated some kind of engineerable FTL I'd take the possibility that at least a few UFOs are ETs very seriously.
This looks really awesome, thanks!

Indeed. I have full coverage with Geico, as well as uninsured motorist coverage, damage etc.

Well the other night some asshole decided to pac-man all the cones on the highway late at night so we had to navigate a field of almost impossible to see cones (the borders are black and there were no lights up). Several cars, including mine ended up running over a few. I got lucky as it just messed up my paint a bit on the front bumper and I lost a license plate. Two other vehicles crashed over it, really sucked.

Called Geico when I got home and was informed I don't have collision coverage. They told me for this I would have needed comprehensive coverage and collision coverage.

Well joke's on them, my renewal is this month and I'm bouncing. I'd rather find another company that won't weasel out on me. When I signed up I said I wanted to be covered no matter what. I pay enough monthly I should be.

Forcing nsurance (health and renters, cars,etc) should be illegal,it doesn't work as it should. It ends up being a tax we pay to still have to pay out of pocket no matter what.
Some things are better done in person.
I found it a lot of fun to interface with the TI calculators directly using the wonderful ArTICL Arduino library[0]. You can cobble together a link cable to imitate another calculator and hook it up to your microcontroller of choice.

I enjoyed making a QWERTY keyboard and news app over WiFi using the tiny ESP-01 (as, coincidentally, @shakna suggested in this thread).

Wow, 60 psi? Thats like 40 meters of head. So you must be using booster pumps to get the pressure.

Never knew this.

In India, 99.99% of all homes have gravity flow and static pressure, so except for very tall buildings, no one gets pressure more than 5 - 10 psi.
We have completely different observations.

I spent last December in London and saw scant respect for the rules during the second wave. A minority of people wore masks, and few of those wore them properly. I was invited to a few house parties and festive gatherings.

Then I spent January in Paris IIIe where mask compliance was much better, but the streets and supermarkets were heaving before the daily curfew. Squeezing down aisles to buy supplies for dinner. Friends publicly complied with the rules but had big house parties every weekend.

I departed in shock and with an understanding of the European case numbers. There was no discipline, everyone seemed too fed up and bored to care anymore. Abstract anonymous others be damned.

Returning to zeroth world east Asia was a relief. Everyone, and I mean 100% of everyone, wears masks properly.

That originally happened before any official requirement. People go out when there are zero cases, but when a community transmission case happens the streets go quiet for a while, cases disappear, then nearly normal life resumes.

While health might play a part, discipline, a sense of community respect, and a competent administration seem far more important.
