> Cost to get mass to LEO is $2600 per kg so if we want 100 special order deliveries of 1-ton rods from God that's $2.6mil per rod

Who is that demonstrated a system capable of delivering these with a CEP that would give it, say, even odds of a hit on a carrier with 100 shots?

> aircraft carrier and destroy how many billions of dollars worth of F22s and ammunition?

$0 billion worth in of F-22s, because Sea Raptor never happened.
Rods from God are only simple at a high level, but as always the devil is in the details.

1. You have to position the rod satellite in the right orbit, or have enough so one is generally over the target.

2. Then when the order comes in to kill the carrier, your 1-ton rod plus satellite has to de-orbit from ~8km/s. Basically it needs the rocket that launched it, but up in orbit to drop it back down. (It's not quite so bad because gravity is assisting rather than fighting as during launch, but it's still a decent de-orbit vehicle.) The de-orbit takes time, and either you're dropping from ~1000km up or re-entering at some kind of ballistic arc from ~200km up.

3. Obviously the carrier will be maneuvering the moment that massive de-orbit burn is detected. So when course corrections will be necessary throughout the re-entry and maybe even into terminal flight, when your rod is hypersonic in the thickest part of the atmosphere, sheathed in sensor-blinding, comms-blackouting plasma.

(I'm assuming a CIWS—point defense gatling—throwing up a cloud of metal wouldn't do much to the rod, nor would an IR missile be able to hit the rod, but maybe those things could alter its trajectory enough to cause a miss.)

4. Then if you actually hit the target, did you over-penetrate it, smashing a 1m hole clean through the hull into the water, or did the rod explode like a bomb against the hull? (I assume the former but am very unsure here.) If it's just an unstoppable but small hole, damage repair teams would patch it and seal off those compartments to keep the ship fighting.

So in the end, you have a very expensive (let's use your $260M), unmaintainable hypersonic slug that everyone can see launch (and who launched it) and it might be able to poke some holes in a carrier.

Or you use normal hypersonic missiles, which should be harder to detect launching, more maneuverable, and might deliver explosive or nuclear payloads.

Or you launch a swarm of hundreds of relatively cheap anti-ship missiles and just overwhelm the carrier defenses that way.

So I agree the dominance of the carrier will last only as long as the next great powers war (and also that guided missile submarines might well be the future) but it's from fear of God raining down tungsten wrath.

At least right now, cheating in chess online has not happened at the very highest level of the game. There have been GMs that have been caught cheating but as far as I know never a top 100 player. The ideas in the article seem focuseed on solving a problem that does not yet exist.

On the topic of combined human/engine chess, this is something that does exist https://en.m.wikipedia.org/wiki/Advanced_chess. It hasn't really gotten any serious traction, but I think it would be something interesting to see. I suspect that chess engines are so far advanced now though that humans would add nothing.
I'm definitely biased, I agree. I don't respond to discussions about the trials for a number of reasons. It's a sensitive issue. It brings out the worst in people. Statements like "riddled with sexual abuse" show your biases. I used to respond to such discussions in the past and I've learnt they're mostly filled with people who have a weird fascination with such events and no good comes from engaging. The trials have taken place, people charged, served their time, and the island is moving on. Just like when similar events happen in other places around the world, and then the world moves on, my belief is that the entire island shouldn't be punished for what happened for all eternity.

1/3 of the male population at the time is, what I think most would agree, "riddled with". I'm certainly biased against huge populations of abusers, yes.

I really don’t understand what people mean when they talk about the law of supply and demand with housing. What exactly does it mean for a demand of housing to go up? Population growth? Immigration? Or is it speculative buying and landlording? What about supply of housing? Does public housing mean increased supply? More shelters? What about squats? Or are just talking about municipal zoning?

How does the economic law of supply and demand apply here? Everybody needs a house, lest they get homeless. By applying the law of supply and demand to housing you will inevitably get speculators and landlords—that is unless you regulate the market heavily—and with that you get stakeholders to the market and lobbying to policy makers. Then there is a serious power dynamics in favor landlords. So regulations are most likely not gonna favor tenants, who risk becoming homeless.

Or does demand here refer to favorable neighborhoods (as OP hints at). So a new light rail station connecting to work sites increase demands for housing in that particular neighborhood at the cost of other neighborhoods who will now see reduced housing prices and increased vacancy? How is that good either? This seems like you (and OP) are willing throw some neighborhoods under the bus to gentrify some neighborhoods while impoverishing others. If not then what kind of demand are you talking about?

No. What I want is for the market to stay away from housing... Or at the very least give me the option of public housing so that I personally have the choice of opting out of this silly game. Housing is far to important to my well being for the rich folks to play their silly games over.

In general, it becomes a good thing if it helps more than it harms.
Email has read receipts, too, and I turn them off there, too. When I send a message to someone, it's none of my business when/if they've read it, or when/if they're replying to it; they'll respond when they choose to respond. That it generally orthogonal to the actual medium for any asynchronous medium.

Team messaging (like irc, Slack, etc), txt, and email each have their own use case and fill different roles.
Why is NPM so consistently awful? It seems like there's a new scandal every year, whether it's packages getting hijacked, packages getting broken, fundamental parts of the system not working...

Great writeup but it was a bit weird that the choice was Postgres vs Cassandra... Those are two very different projects.

> Recently I was conducting an evaluation of several different databases for a messaging workload.

> While PostgreSQL was a strong contender among SQL databases and had given good results in early experiments, I was looking for the ideal NoSQL candidate.

Maybe I just don't know much about these projects but is Cassandra a common choice for a messaging workload? Postgres also strikes me as a weird choice -- you're going to need to do some partitioning (or use a plugins like timescale and/or citus) to make things scale gracefully (not web scale per-say, but just reasonably active messaging over a long period of time).

I got some inside information that LINE (a popular messaging app here in Japan) has a large Kafka cluster -- maybe it's 100+ nodes by now.

In the end I do love me some postgres propaganda though, it's a fantastic tool -- IMO the best RDBMS out there, and maybe even better for some usecases you wouldn't expect.

On the Cassandra front, A bit disappointing to hear about the issues uptaking the patch. This kind of improvement seems well worth reviewing, but the priority is low., I do wonder where Scylla[0] would have been on the spectrum of performance.

[EDIT] - It looks like cassandra trunk wins on the margins[1], despite this speed up, so it's not so cut and dry.

"label it as character flaws because it implies that it is an immutable property"

That's a misinterpretation, I believe. Nearly every story involves character development; there's no reason to believe that it's immutable.

Some elements of character may be less mutable, or at least assumed to be less mutable. But character overall is a continuous work in progress.
Many smaller one-person yachts visit the island, they anchor offshore and get transport to the island via the islanders coming out on the longboat. Yachties stay overnight on their yacht for safety reasons - there have been incidents of them breaking away from their anchor.
No, they wouldn't be.

The shallowness is exactly what makes it easy watching for large groups that can fit in whatever gaps they find with local preferences, combined with making it much easier for localised edits to be done.

Whether the movie includes comic book superheroes or not is not relevant - arguably, many a comic geek could probably point to reduction of depth in the plotlines in some of those. Same goes for typical US DoD propaganda pieces ^W^W^W^W Hollywood action movies, Disney reboots, "Butchered Love Actually Remake" CXXVII, and many other big budget plays that use this approach.

It works because while it's not a great meal, it gets you an equivalent of mcdonald burger in foreign country. Not great, not terrible, and the local adaptations probably aren't big enough to stop it from being "safe" choice.
I agree, but would add -- five years ago "Google has been stymied by copyright" was most of the story for them, but today "Google is subject to political pressure to exercise editorial control" (to put it charitably) is as important.

Not to diminish the disappointment over Google Books being curtailed (Google actually went to court for it!), or DMCA takedowns on Youtube or Google Search results. But we also have to admit that today Youtube is exercising editorial control to ban opinions they don't like, and that Google Cloud is as quick to drop "the wrong kinds of customers" as the payment processors everyone was complaining about ten years ago.

Maybe "getting ahead of the censors" minimises the damage, maybe it encourages the censors. I don't know. I guess the company is run by smart people who want to make as much money as possible in the long term, so it's likely good for consumers on net. That said, it's a shame we don't see them fighting for those principles today.

> Privacy for the server: A malicious client should learn nothing about the server’s dataset X ⊆ U other than its size. In particular, it is important that the client learn nothing about the intersection size |id(Y̅ ∩ X)|. Otherwise, the client can use that to extract information about X by adding test items to its list Y̅, and checking if the intersection size changes.

If one of your pictures is a false positive hash collision, you'll have no idea until your front door gets broken down.

> Privacy for the client: Let X be the server’s input from which pdata is derived. A malicious server must learn nothing about the client’s Y̅ beyond the output of ftPSIAD with respect to this set X.

Apple can't check whether a hash match is a false positive or not, because they only get the matching hashes and not the pictures that triggered them. So if you have a bunch of false positives, your front door is getting broken down, with no opportunity for a human to realize the problem and intervene.

> The protocol need not provide correct output against a malicious client. That is, the protocol need not prevent a malicious client from causing the server to obtain an incorrect ftPSI-AD output when the protocol terminates. The reason for this is that a malicious client can always choose to hide some of its data from the PSI system in order to cause an undercount of the intersection.

Their protocol isn't (and can't be) secure against the one attack that the people that this system is supposed to catch would actually commit.

> Moreover, a malicious client that attempts to cause an overcount of the intersection will be detected by mechanisms outside of the cryptographic protocol.

This seems eerie to me but I can't put my finger on why.

Color film is similar to the Foveon sensors I was talking about, since it’s actually three different emulsions stacked on top of each other, while most digital sensors are actually monochrome with a color filter (just all color filters tiled on a single piece of film rather than three separate strips like Technicolor).

Although fun fact some of the early Minolta digital SLRs (“RD-100”?) actually did have three separate sensors, and also interestingly they used telecompressors to “resize” the image down to the smaller sensor so that the lenses effective focal length didn’t get super long on the tiny sensors they could cost-effectively produce in 1993. And this also somewhat mitigated the loss of light from having to split the light across multiple sensors.

It is already the taxpayer’s responsibility to report their capital gains.

The IRS has issued "John Doe" summons to Coinbase in 2016 [1] and Kraken in 2021 [2]. They also already gave warnings to 10,000 US tax payers, in 2019, that they thought did not pay their fair share of crypto taxes [3]. They are working with plenty of information already.

Anyone who chooses to omit capital gains from crypto may also see consequences in the future. Most blockchains are immutable public ledgers. The auditing of this technology will only get more advanced over time.

To your point about depositing, how does the exchange know the original price that the crypto deposited was purchased at, when it could’ve been purchased elsewhere (including a different centralized exchange like Coinbase, Kraken, KuCoin or Binance, or a decentralized exchange like Uniswap), or perhaps it was mined, or perhaps it was from a fork of another coin (with the current US tax laws, the cost basis is zero from a fork). It’s not as simple as you are making it sound when the source of the crypto is unknown.

How would formal verification actually work for a single exchange to calculate cost basis, i.e. the gain or loss, considering all these different cases? The people making these laws do not actually know in practice how these things would be enforced by the exchanges. They are trying to fit old securities laws into a new technology. Just saying that's it's too complicated is not the right answer. I think laws should be adjusted to accommodate for new innovations. I also think people should pay their taxes and crypto should not be used as a method of tax avoidance.

"So if you have a bunch of false positives, your front door is getting broken down, with no opportunity for a human to realize the problem and intervene."

Well, technically speaking, once enough security vouchers have been submitted and reached the threshold as stated, a report will be sent to an Apple employee (somewhere). The vouchers will then, combined, be decryptable and contain grayscale low-res versions of the original image for confirmation, in which case the NCEMC (National Center for Exploited and Missing Children) will be alerted and law enforcement.

I'm just pointing out that your door being broke down is by multiple false flags and a human will get a chance to "realize the problem and intervene" before it goes to the FBI or whatever. Not saying I like this system, just making a nitpick on your criticism. I don't really know how else you could have a human intervene without "breaking down your door."
