Well, there's kind of a chain of intuitions here that are off by up to orders of magnitude. First, YBCO has a critical temperature of 93K, not 23K or so as you've suggested (albeit not as a value for YBCO). In other words, there have been advances in high temperature superconductors. Second, the magnets will not heat up from having large currents running through them. This is the point of superconductors. So, this estimate of resistivity is high by several orders of magnitude. Third, any estimate of the total energy of the hot plasma that gets us anywhere near verbiage hinting at explosions is too high by several orders of magnitude. You could typically extinguish a burning plasma by blowing gently on it. Finally, the thermal gradients aren't nearly so dire as, you know, 200e6K immediately next to 90K. There is typically over a meter of, in order: near-vacuum; inner wall; flowing lithium blanket; outer wall; and liquid nitrogen or other cryogenic coolant, all between the plasma and the magnets.

This is the farthest thing from a recipe for disaster.
We'll have to agree to disagree.

Just think about the way modern media companies constantly shame and stigmatize people. How are you going to even define when someone is "shamed" or "stigmatized"? Aren't there people who should be shamed and stigmatized?

This seems completely unworkable and guaranteed to make absolutely no one happy other than the lawyers making money off of all the frivolous legal disputes.

I worked for a startup ten years ago that stored a lot of user data.

A batch of drives from the manufacturer had some sort of firmware issue. It affected a lot of users.

Essentially their data was put into read only mode by our service. Two weeks went by before the manufacturer came out and worked on replacing the drives and migrating the data over for us.

Unfortunately the data center admin at the time didn’t have backup servers and drives in place and lost his job over the snafu once the drives were replaced.

Always have backups of your data and make sure the drives are good quality.
Comparing Venus to Earth is silly. Venus's atmosphere is mainly carbon dioxide. On Earth it is a trace gas, measured in parts per million.

Carbon dioxide blocks a narrow spectrum of radiation. It acts a lot like food coloring dye mixed in water. If you mix in a couple of drops, the change is dramatic, but if you double it and mix in a couple more, the change is much less so.

If the only effect on the atmosphere was the CO2 greenhouse effect, and we added 10x the CO2 the average global temperature would only rise a couple of degrees.

The issue and the controversy that surrounds CO2 is how the Earth will respond to this added heat that it can't get rid of. If it's a tipping point, and will end up in a death spiral of factors compounding upon each other (ex. the permafrost melts and changes the albedo of the earth and that causes more warming, etc.) is where the science of climate change actually is.

The problem is that climate is complicated and no one can predict exactly how it will behave. This is why there are ton of models and it seems no one can agree upon how much the effect will be.

Climate skeptics will argue this is because the science done so far is mostly conjecture and very weak, and the conspiratorial among them will say that only studies that support climate change are being published/funded, so there is a lot of bias to make out that their evidence is stronger than it is. There has also been a lot of modifications to historical temperature readings, (this seems to be with good justification), but I personally can't judge.

Whether the effect of CO2 is going to be large or small is outside of both of our grasps, and we really have to trust on others to make that determination, unless you're willing to really learn the science behind it.

However, your list of reasons are just muddying the situation even further. They are easily debunked and if you proclaim them, and people find out they don't hold muster, you may drive people further into the climate change skeptic camp, which I don't think you really are trying to do.
1. Is this possible for Election and not for, say, Falcon 9 due to the difference in mass?

2. Is that a retro burn in the animation or reentry heating?

3. Are they gonna catch those discarded battery packs too? Should be easier than a whole first stage.

4. If they nail this, catching everything by helicopter shouldn't be that much harder.

I think the point is that any dietary or lifestyle recommendations to achieve a long life need to be reassessed.

Do recommendations to reduce intake or intermittent fasting rely on unverified population ages?

My personal take on living long is to get regular health checkups and seek medical care early if there are any issues.

What do people like Queen Elizabeth, Warren Buffett, Rupert Murdoch do to remain healthy and still working at their age?

For me, Windows (7, 64 bit) behaves exactly as you report for Linux. I would love to be able to get Windows to behave like it does for you. What version were you using? Did you tweak any settings?
I know these problems are serious, but I feel there is a fun and reassuring aspect to them. Back in the 90s and early 2000s we thought anything can be hacked by any clever person. Then the 2010s happened and almost all software, even Windows, became near unassailable fortresses, especially systems like iOS with their tight control of the OS. Sure, a 0day drops every now and then, but we all know that it's basically impossible to attack a modern well configured system.

These hardware bugs turn that idea on its head, suddenly the whole ghost in the shell hacker style dream is again a possibility. A motivated person or group of persons might go and hack any system out there. And that's really a bit reassuring, it's a little bit scary to think about how our lives might be ruled by these systems that are unassailable. I'd like to at least stand a chance when technology turns on us.
Ok, but this seems to belie your previous point about groundwater contamination. If the bore lining is theoretically a permeable structure in any well, then using fracking techniques would almost definitely make it more likely to crack, right? You certainly can't control where the excess pressure you're providing goes, it's hydrostatic. Therefore it's much more likely that a fracked well will contaminate layers above the production layer, right? Not to mention the fracking fluid contains extra materials which are likely the cause of any deleterious health effects.
I believe LineageOS used to be called Cyanogenmod, and it's a fully free/open source implementation of Android. openGapps is Google Apps (like Maps) that you can install without having the Play Store.

Using LineageOS lets you do many more awesome things with your device, but financial apps (and even some apps like bus ticket apps) often don't work on this setup because it's viewed as insecure.

That's not how the burden of proof worked. It was established case law that any collected rainwater without clear water rights was infringing.

It's like if you went into fight a speeding ticket by questioning quality of the radar gun. I mean, in an ideal world you should be allowed to, but it's not going to fly. Our common law style system has this overarching goal of internal consistency, and there's been tons of cases where the radar (or maybe some relative of the radar, but close enough as far as the court is concerned) has been legally found in the past to be trustworthy. It's also in the Court's best interest to have this line of reasoning because it saves the court from having to rehash the same arguments saving the court immeasurable amount of time. About the only way you can get out of that situation is new legislation.

The courts here had gotten into a similar state where it wasn't really willing to hear new evidence on the matter, and needed legislation to patchfix. Something something checks and balances.

I worked as an IT tech in a school district with 9 buildings, each connected by directional antenna. The speed wasn't great but certainly usable enough, even for video. This was back in 2000 and the guy maintaining the network learned it all on his own as far as I can tell. Weather was a problem for the network as outages were fairly common. We had an outside tech who would come out to fix the radios once in a while. Overall it got the job done, but eventually the district ponied up for a fiber connection to at least a few of the larger buildings. I helped lay new wiring for most of the buildings.
That is called a "crack". :-)
My local handyman (he is a real engineering, just does this after getting out of working a corporate job) that is booked months in advance told me a story. He was listed on Yelp with perfect reviews. One day Yelp called him and ask him about some paid for service to improve his listing. He said no thanks. A few days later he when from showing up in the top of the search to near the bottom. He is a great guy and does fantastic work. I was done with Yelp from that point.
Slackware launches Prateon for continuation of the project
Reading large files using direct IO defeats kernel read-ahead, which means you have to take on the complexity of reimplementing it in userspace, or the performance hit of not having it.

This is a good reason for programs to use buffered IO even when they are reading a large file once, so yes my comment was entirely on point.

Hmmm, that is a relatively high delta-v to change inclination that much (~1.5-2 km/s for a ~12-15 degree difference). On the other hand, if the shared payloads are light enough (and they very well may be, particularly if the launch is undersubscribed), the upper stage could do the orbital transfer and should have plenty of delta-v to do so (particularly with a droneship landing) considering F9 regularly does recoverable flights with many tons through 2.5km/s above LEO.
Like he says in the video, catching is actually the easy bit.

Having the booster survive the re-entry heating and aerodynamic loads while only using passive methods to slow it is the hard bit.

No idea why Apple hasn’t created their own review system within Apple Maps.
a big drawback is not performance but that most lidars are expensive and fragile.
I'm a little dismayed that your first link is, as you note, from the 80s, and that your second link is about ITER, another old design that is orders of magnitude larger than the scheme in the article, a size it must have due to the very same technical limitation that the subjects of the article are working to remove.

But that is hardly the only disappointing thing about your post; It's just fear-mongering. Of course a development reactor isn't going to be "manufactured," but "built." What prototype has ever been manufactured before it was proven? One of the very points of fusion is its low proliferation risk. I don't know why you burden fusion with "extreme safety," either. Bicycles don't have "extreme safety," and we seem to do just fine. The impact of a fusion "disaster" is probably much less than a fall off of a bicycle.
Right, which make the opportunity that much bigger.

For new startups, it would be much worse if companies respect customers, did not lie, did not mislead.
1. yes - they don't have the mass for the fuel to get back
2. reentry heating
3. probably not (I think it's the 2nd stage that drops its batteries)
4. because they don't have the mass to do the return they don't have a lot of options

Even though it's supposedly not feasable to exploit on Linux, there are fixes in the upstream kernel now and the changelog entries have some technical details. If I'm understanding this correctly, AMD systems don't speculatively execute GS-based accesses after speculatively excuting SWAPGS like Intel ones do, but that isn't enough to fully fix the problem on Linux because there's a conditional branch over the SWAPGS instruction which can be speculatively executed. Since that execution path doesn't have a SWAPGS all processors will quite happily continue speculatively executing code that fetches data via GS.
To sum up. If I use Lidar - Lidar is good. If I do not use Lidar - Lidar is bad.

Also autocomplete. I had a samsung phone running android that was almost omniscient in knowing what I wanted to type or keeping track of what I had just been reading or searching for and giving me suggestions based on that (like if I had been reading about a restaurant and then went to send a text to my wife it would give me prompts about the restaurant, which is exactly what I wanted). iOS autocomplete is woefully subpar in comparison.

Looking at the title I though why would you even need that. And 10 min? Why not 5, or even 1, you'll get fantastic granularity of your stats. But then of course it will be only stats you've got and no real work done.

Here's a problem: people often share screenshots with the address bar in the screenshot.

If they share it from Safari with default options, the address is mostly useless, it's just the domain (and www may elided), but it doesn't even look like a url, so whatever.

If they share it from Chrome with these new options, if it's like the last time Chrome released this, it looks like the full url, but it's not:

When you go to https://example.org/some/deep/url it may very well not be the same as https://www.example.org/some/deep/url and adds an extra layer of confusion to figuring out whatever the issue is.
> You see yourself as some benevolent being moving humanity forward but reject any criticism of the costs of your actions.

I reject specifically your criticism, the criticism of cynics. I (obviously) don't agree with your characterization of which policies are "failed policies that end up costing others" or "how the world operates". Humans are of nature but also possess the ethical and rational systems to rise above it. We're not bound by our natural impulses; on the contrary, our gifts oblige us to be better than them.

Bluntly, I have no interest in living in a tribe with my Dunbar's number of tribespeople, organizing my thoughts and our policies under some presupposed limits of ambition. My ambition is boundless. So I say again, if you want to close ranks and subvert broad collective action and live in fear (or as you would say, some kind of steely-eyed realism) go dig a hole and do it well away from me. I've no interest in that moribund nihilism.

I believe every major distro that jumped to libav has switched back. Some appearance of bias may be just a statement of fact. ffmpeg frequently merged changes from libav, but not vice versa. The newly commissioned (around the time of the fork) library libswresample for example was never brought over to libav, despite being far more ergonomic than libavresample.
