The rotors are 1.2m in length and spin up to 2500rpm.

This gives circa 160m/s (560km/h) linear speed of the rotor tip.

Pretty much impossible for the rotors to survive touching anything at that speed.

The rotors are probably already designed with absolute minimum margins. Not only the rotors are part of the package to deliver to surface of Mars, then they have to be lifted in thin atmosphere, but they also need to be spun up to very huge speeds and then quickly controlled to keep the craft stable. The mass of those rotors is critical to how well the craft can be controlled.
> So far these mostly haven't been able to cross process boundaries

Actually, most Spectre vulnerabilities, including this one, do cross process boundaries when they are first discovered, and kernel and microcode patches are needed to implement mitigations against this -- typically flushing some cache or something when switching between kernel and userspace. Often these mitigations hurt performance.

> things like Cloudflare's Workers are looking a lot more suspect.

Cloudflare Workers uses a completely different approach to Spectre mitigation, based on slowing down observability of side channels to the point that an attack isn't practical. More details here:

https://blog.cloudflare.com/mitigating-spectre-and-other-sec...

This approach doesn't target specific forms of speculation and therefore tends to work against the whole class of bugs, including ones that haven't been disclosed yet. The down side is that it requires restricting the programming environment including changes that would be backwards-incompatible for browsers, and it certainly wouldn't work at all with native code. Luckily Cloudflare Workers was able to design for these constraints from the start.

I'm the tech lead of Cloudflare Workers, so I may be biased. But, my honest opinion is that the cloud hosts that accept native code are in a much more precarious position than we are.
I hear praise of current standards which just makes me laugh. The standards are pathetic. Just look at any other industry. There are always detailed rules and you will be told when you break them with great accuracy. The inquisition had higher standards than these.

I honest to god can't develop software or run any business if I cant rule out faceless executive punishment without clarification. I cant even take web development all that seriously with googles dictatorship.

I believe this to the the right analogy:

Imagine building a brick and mortar store before asking for permission to open it. You get the permission but move some shelves around and buy a new carpet. You get a letter from Acme Corporation: We don't like something! Your business is hereby terminated. You naively reply and ask why? Is it the shelves? Then they visit you, wack you over the head with an AK47 and burn the place to the ground.

Outside there are people cheering the purification.

> Can you give an example what will happen if states do not use standardized tests?

Compared to any of the individual incremental mandates? They’ll have a lower ratio of cost to instructional time and a more efficient educational system, probably. While the requirements are often tied to consequences, they are rarely tied to the kond of systemwide analysis of results against other factors and process improvement that would make them systematically useful rather than theater. They are generally “accountability” measures that assume without any empirical basis that the results are within the control of the entity held accountable and that the consequences attached will force decisionmakers to make changes that result in optimization of the results.

Oh, and standardized testing companies will make less money. Hence the lobbying.

That's wise. Still curious what local utility says. Might be eye opening. I used to supervise a treatment plant, we were well prepared to deal with disasters.

FYI a flocculant can be used to settle out really dirty water, it needs to be mixed well to work correctly. Flocculants include ferric and alum. Bleach is typically used as a disinfectant to reduce bacteria and viruses. Oocysts are not destroyed by chlorine and have to be filtered out. Most surface water treatment plants use sand filters. Granulated carbon filters are increasingly common to remove trace chemical contaminants, but these will also adsorb chlorine, advise disinfectant after the filter step.
We have Apple Express Transit in Chicago too (Ventra) and it works great. The great part is one doesn’t need to unlock the phone — because of that its arguably more convenient than a transit card.

I used Apple Express Transit with New York City’s OMNY system last weekend and it was similarly amazing. I brought my Metrocard with me just in case but never had to use it.
They are planning to release a preview version this year with support for ARM VMs only, the priority will be for Linux, as Microsoft didn't release an official Windows ARM version yet.
It could be, but my blind guess is that if there are any intelligent lifeforms out there, they're so far away that conventional propulsion craft would have to fan out and run for so long that it's unlikely they'd happen to run into us at all, or if they do, not at a time when any of us exist. And if they were already doing that within a reasonable distance from us, I think we'd probably have already seen evidence of some of the swarms somewhere.

And it'd also probably have to be immortal autonomous machines rather than anything biological, which wouldn't necessarily be as useful, unless they fully merged with them or created ones that were much smarter than they are. (Which I suppose is pretty possible, given we might do the same within a century or two.)

My guess is we may unfortunately possibly be the only intelligent life throughout all of reality up until now (extremely speculative, I know), or that the few civilizations that do exist or have existed are so spaced apart from each other that it's very unlikely any will ever run into or observe any of the others without some kind of major FTL breakthrough.
Ah, trendy bro science.

If you think glucose is bad for you, you lack a rudimentary understanding of biology. No, ketones do not replace glucose. But it’s ok because you probably lack rudimentary understanding of protein and most other health related things.

If you've for some reason been listening exclusively to the anti-BLM garbage being spewed by right wing media, sure, I guess that's a reasonable thing to believe.

But there's a massive difference in saying "Policing in this country is broken - cops kill too many people" versus "Cops and lot of white _and_ black people.. see? BLM is a pointless movement". Right wingers seem to love to pretend they're saying the former when they actually mean the latter.

I think this would actually, in the long term be good for Amazon. If it forces them to clean up their third party sellers and co-mingling of inventory and verify supply chains better, I would be more comfortable buying high value items from them.

Right now as it stands, for high value items or items where counterfeits are dangerous (think chargers) I have been either ordering at brick and mortar stores (Walmart, BestBuy) or direct from the manufacturer (Apple, Anker, etc)

My safety is worth a few extra dollars, a short trip to the store, or a few days wait on shipping.
I agree. It should cost them almost nothing to run (on a comparative basis). They made $15B I believe. $100M/year + payment processing fees seems generous.

When I've done it in the past the reason was that the "downloader" was more like a bootstrapper to get the app on the machine with different logic if the app was already installed/not installed, and to migrate between versions if necessary - without corrupting the existing installation, if it exists.

Download & Install is filled with points of failure and have few ways of performing the modifications atomically. Its better to have this correct than have nice information displays. But this depends heavily on what the app structure looks like.

> Especially when the custom downloader doesn't suppoert resuming interrupted downloads, display remaining time, current download speed or how much data is being downloaded

These things are not always easy, are usually lies, and add very little value to the application. Be happy they haven't hyper optimized first time installation or new user onboarding, since you usually only do it once.

The conclusion makes no sense as glucose is half as sweet as sucrose, which is half as sweet as fructose. Does anyone have the paper for how they controlled for this? It makes perfect sense if sweetness is the stimulant.
I did read your linked explanation, I did not get a chance to read your sources however but I will when I get a chance. You don't need to be so condescending. Are you in the medical field by chance? Anyhow my concerns around the virus aren't so much with the tests but with the lack of data on the long term effects of the new vaccines. Since I am not in an elderly age group, I am reluctant to take the vaccine without at least waiting a few years to observe if there are any other effects.

What would be the point if Google's signature would still validate. If an author wants to share an app with a different signature outside the appstore they can.
A curious conversation would come if the author made an argument with more substance. This doesn't have the merit to any response besides the ones that point out how incredibly flawed the original argument is. It's hard to assume an intention of honest debate.
Why My Transition Is My Dream Come True – Ray Dalio
A lot of gossipers, haters, and narcissists hide behind the activist label to carry out their personal agenda. If you are building policy that allows activism, you need checks and balances against this free riding behaviour.

If you don’t check the behaviour it can take over like cancer. The gossipers and narcissists hide behind activism and the activists support them as one of their own because they align with the activists goal. People who do not want to deal with these people eventually leave for places without such policy and you are stuck with all the bad actors.
Polio isn’t airborne and is much less transmissible so the vaccine doesn’t need to be as effective to stop the spread. Vaccination programs were also very successful.

They have stated they have no intentions of using the rover to do so. I would think given this is now “extra credit” doing so becomes even less likely.
I think that nativecomp represents a huge leap forward for emacs. I continually give kudos to Andrea Corallo and the entire team for making this a possibility.

I think that the next major leap for emacs needs to involve the garbage collector and allocation logic. I think that a large class of performance optimizations would be possible with an improved GC, including improvements to emacs existing threading capabilities.
E.g. in Israel, B.1.351 represented ~5% of dual dose vaccine breakthrough events when it was at a prevalence of less than 1% in the population. This means that B.1.351 is better at causing infection of people with the vaccine than the previously prevalent variants.

This is despite people with the vaccine having higher neutralizing antibody titers against B.1.351 than people naturally infected with previous strains.

Therefore it seems very likely to expect that B.1.351 will also cause reinfection at higher rates than we've been used to, since it appears that people with the vaccine are more protected than people naturally infected. This is especially true if people who were infected earliest have their immune responses start to wane.

Again: I don't think this is a huge absolute risk. I just think it's significant enough to be a significant confound for those of us trying to guess what Rt would be with a return to baseline behavior, and enough for people who've "had it" to be less protected than they might expect.
To add some more context on this, when you provide an app bundle the Play server looks at your device's display size, density, OS version, and architecture. If your OS version is new enough (L+ I believe), it can send you a bunch of split APKs. That means one big APK with DEX code, one with just the armeabi-v8a native code, one with just English translations, one with just xxhdpi assets, etc... In theory a developer could build all these split APKs, sign them, and upload them to Play.

However, on older devices that don't support split APKs, Play must compose and sign one custom "fat APK" with all of the stuff specific to your configuration, on the fly. There are a lot of different options for this (you can generate them using bundletool if you're curious). The upload size of all these redundant APKs alone would be a huge burden on developers.

This isn't to say that there couldn't be a way to do APK splitting while maintaining the integrity of the app signing system. My guess is that it wasn't a high priority to do so.
Yeah, in my experience it takes X years of experience at a company that is already using a monorepo + blaze-derivative tooling, for the costs of setup and maintenance to make it worth adoption.

That X is mostly a function of how open you are to the idea that maintaining + using a centralized, language-agnostic build graph is a Useful Thing.

But once that X is crossed, I don't think it's possible to happily go back to a non-monorepo environment. :)

FWIW, we've used Pants successfully for years, which has excellent Python support. However, we're in a long-haul migration to Bazel, so you might be better off revisiting Bazel if you want to invest in something that's extremely likely to issue dividends over the next 10 years.
I suspect, but don't know for sure, that this is related to funding for staffing in command centers and such. "Fly it until it breaks" means that somebody must approve an uncertain and ongoing expense without any results to show for it.

If you re-frame it as an initial experimental mission, it's a smaller and more defined budgetary request. You can outline potential extra-time scenarios, but presumably those are a lot easier to get approval for after the initial window is a success.

edit: It also occurs to me that framing it as a series of smaller phases with well-defined goals and benefits also makes it easier to communicate a straightforward message to the broader public about the mission.

I don't think that being able to replace a library at runtime is a useful enough feature to justify the high maintenance cost of shared libraries. Like I complain about in a comment below, the cost of shared libraries is that an upgrade is all-or-nothing. If one program on your system depends on a quirk of libfoobar-1.0.3, and another program on your system depends on a quirk of libfoobar-1.0.4, you're fucked. You can't have both programs on your system, and Linux distributors will simply stop updating one of them until the author magically fixes it, which happens approximately never. And, the one they stop updating is the one that you want to update to get a new feature, 100% of the time.

It's just not worth it. A binary is a closure over the entire source text of the program and its libraries. That's what CI tested, that's what the authors developed against, and that's what you should run. Randomly changing stuff because you think it's cool is just going to introduce bugs that nobody else on Earth can reproduce. Nobody does it because it absolutely never works. You hear about LD_PRELOAD, write some different implementation of printf that tacks on "OH COOL WOW" to every statement, and then never touch it again. Finally, dynamic loading isn't even the right surface for messing with the behavior of existing binaries. It has the notable limitation of not being able to change the behavior of the program itself; you can only change the results of library calls.

I never want to see a dynamic library again. They have made people's lives miserable for decades.

This would completely change the signing structure but its feasible. Doesn't work for splitting files but maybe that's ok. I think BlackBerry would have you sign every file in a build but man was that a pain in the ass. It took forever for some reason.

>>>Also could I just sell the lot for a reasonable price and not have to go through them all?

I wouldn't recommend that. If you sell them as "bulk", you might get something like $10 for 10,000 cards. Buried in those 10,000 cards you probably have several cards that are worth $20-$100 each. This was my exact scenario over the past 2 years. I took a trip stateside in 2019 and got back into Magic (my cards were at my mother's house) after a 15-year hiatus. I started playing in 1994/95, so I had a pile of now-kinda-rare cards that were worth FAR more than I ever expected. But I've had to dig through my boxes and figure out what I had. Instead of selling them all off, I mostly trade them to local players/collectors in exchange for large quantities of lesser-valued but still useful cards for making EDH decks. I'm keeping my most valuable card though, the $800 Nether Void.

I recommend using the mobile app "Delver Lens" to scan your cards rapidly, which I think can export the card list as a CSV format. Then try to import that CSV list into a good card management site. I use Deckstats.net, which will display prices for your collection pulled from 3 different websites. This should make it slightly less laborious to sort your stuff as well as establish a ballpark value.

This seems like a straightforward description of the problem; what potential solutions / mitigations are available?
I would refer people to the dual definitions of the word "Talmudic"[1] for further proof of this:

1. of or relating to the Talmud (the collection of Jewish law and tradition)

2. characterized by or making extremely fine distinctions; overly detailed or subtle; hairsplitting.

It is extremely difficult to translate rules that were written thousands of years ago into guidance on modern life. Much of Jewish religious tradition has therefore embraced the debate, theorizing, and further definition of these rules into something that is more clear, logical, and can be practically applied by people who wish to follow them.

"Does electricity count as fire?" might seem like an arbitrary and non-sensical question to someone on the outside, but it is incredibly important to how a modern Orthodox Jewish person would practice their religion and they therefore need an answer to it. "Trying to rules lawyer god" through debate and writing on the subject seems like one of the better ways to reach a satisfying and conclusive answer to this style of question.

Yeah I decided a long time ago that I'm not playing that game, adding subscriptions for all kinds of things.

The only recurring charge I pay for is Amazon Prime, because I don't want to think about shipping costs and I like Prime Video (replaces Netflix) and Fresh (free grocery delivery, no need for Instacart)

Other than that, anything that requires a subscription, I can do without.

I've bought one mobile app in my life: Backcountry Navigator. It lets me download detailed maps for hiking and then use them where there's no cellphone towers.

Ingenuity has already fulfilled its mission with overwhelming success, and anything extra now is just a bonus.

Perseverance is still early in its mission. There's no way they would ever have it attempt to push Ingenuity upright, simply from a risk perspective. Why risk any complications with the primary mission, just so you can squeeze out a little more science from the expendable secondary experiment?
