Science doesn't "show us" what you claim. The article you linked is an editorial that is long on vague words like "some" and "many", but the only place it makes the claim you do is in a bit that is clearly presented as the author's opinion, with no evidence or study supporting the conclusion.

You're conflating concerns. Most government systems are required to log the hell out of their inputs and outputs. Making decisions to destroy something based on ephemeral data could happen just as easily on the ground as it could in orbit -- it has nothing to do with what kind of system (large neural network, traditional ML, human decision, or something else) makes the decision or where the decision happens.

I'm not sure what you mean. Do your eyes count as "long range sensors"? Mine can see stars that are many light-years away, and eyes are not a new invention.

They claim to have realized (invented) a better quantum magnetometer and a way to process the data to do a pretty amazing kind of detection. That's one very specific kind of long range sensor, with improvements over previous long range sensors but also limitations of its own. It's presumably not a magic device that Pareto dominates other long range sensors.

What's the differential latency of running a strong model for several turns (or the equivalent) on a spacecraft's power budget compared to a data center's power budget, especially once you factor in redundancy to manage single-event upsets in the huge RAM array needed for that model?

I use Claude rather than a local model because I don't want to wait all afternoon for the quality of results I can fit into 128 GB RAM.

Comment Re:Farm pasture versus concrete buildings? (Score 2) 71

I understood the question to be whether the study controlled for other changes in land use in the surrounding area. For example, northern Virginia has built a ton of new data centers close together over the last decade -- in many cases, replacing pastures. Attributing the results of the whole set to individual data centers would be a methodological error.

They have working software: OCX is intended to replace the current ground system, Operational Control System (OCS). They have launched a lot more than 30 satellites -- in fact, most of them have been decommissioned, although the currently operational set have mostly outlived their design lifetimes by a lot. The oldest active satellites are Block IIR satellites, with a design life of 7.5 years ... and launched between 1997 and 2004 (so the youngest of them would be old enough to drink alcohol in the US).

Sure, it is not a big problem for SSH. It is a problem when you connect to a web site, especially as certificate lifetimes get shorter: you need the whole certificate chain from a root (that your browser trusts) to the web server, which means at least two public keys and signatures and often more.

The NIST-approved post-quantum options and PK/sig sizes (in bytes, for "security level 1", which is the lowest) are Crystals Dilithium 2 (1312 / 2420), Falcon-512 (897 / 666 but computationally expensive) or SPHINCS+-SHA2-128s (32 / 7856 for the smaller but more computationally expensive signatures; same for SPHINCS+-SHAKE-128s). This compares to 32/64 or 64/48 bytes for 256-bit ECC algorithms and 256/256 bytes for 2048-bit RSA. If you are fetching a few kilobytes of text or CSS, this additional overhead is huge.

Yup. I'm waiting for any quantum computer to actually break a non-trivial public key, even of a laughably small order (like RSA130, which was factored by classical computers 30 years ago). Lots of people get famous for papers based on theoretical quantum gates that nobody knows how to realize.

Elliptic curve crypto is vulnerable to the same kind of theoretical quantum attacks as integer-factorization cryptography. You currently need to use algorithms with unfortunate trade-off (large public keys or large signatures/key agreements) to get resistance to quantum attacks.

Assuming quantum computers ever factor numbers larger than 21 without cheating or falling back to deterministic algorithms, at least.

The Second Amendment was intended to be a check on federal power. None of the amendments were incorporated into jurisprudence about what individual states could do until arguably 1890 and not certainly until the early 1920s. Many states had laws around firearm storage for decades. In the 1830s, Massachusetts was the first among several states to generally bar carriage of firearms in public. Texas would follow suit in 1871.

The Heller decision written by Scalia was a sea change in constitutional law, but it laid down important limits that were respected in the MacDonald decision that followed soon after and which incorporated the Second Amendment as applying to states as well as the federal government. Scalia wrote that firearm law limitations were presumptively lawful, and essentially laid down an opportunity for the federal government to prohibit future types of weapons sales by preventing them from becoming publicly available. Here's what he wrote (citations removed).

We also recognize another important limitation on the right to keep and carry arms. Miller said, as we have explained, that the sorts of weapons protected were those "in common use at the time." We think that limitation is fairly supported by the historical tradition of prohibiting the carrying of "dangerous and unusual weapons."

It may be objected that if weapons that are most useful in military service—M-16 rifles and the like—may be banned, then the Second Amendment right is completely detached from the prefatory clause. But as we have said, the conception of the militia at the time of the Second Amendment’s ratification was the body of all citizens capable of military service, who would bring the sorts of lawful weapons that they possessed at home to militia duty. It may well be true today that a militia, to be as effective as militias in the 18th century, would require sophisticated arms that are highly unusual in society at large. Indeed, it may be true that no amount of small arms could be useful against modern-day bombers and tanks. But the fact that modern developments have limited the degree of fit between the prefatory clause and the protected right cannot change our interpretation of the right.

Scalia had no problem with regulating or even banning public availability of broad classes of weapons as long as those available to the public continued to be available to the public. In his view, existing weapons like missiles and new weapons like portable lasers could be banned because they were not "in common use." However, Scalia died in 2016, and the Court has moved to a substantially broader view than he had.

What are you going to do when Nazi Trump really ramps up the persecution? Oh right, sit back and protest and hope the government doesn't murder you all, ie just like Iran did to it's protesters two months ago.

The people who have clamored most over the last 40 years about government overreach are largely those most supportive of Trump's tyrannical behavior. However, the fastest growing segment of gun owners in the last couple of years are those on the left, with even more disproportionate growth among minorities. There are a lot of former military who are very unhappy with the direction that he's taken, too. There are a lot of guns on both sides and not nearly enough police or military to handle them all.

So far, the Trump administration's own overreach has been embarrassing enough to force them to back off. The videos of the deaths of Renee Good and Alex Pretti were bad enough, but the responses by almost everyone up to and including Trump in labeling them terrorists and declaring that the ICE and CBP agents did no wrong before we even had multiple views of what happened caused them to backpedal (even the NRA chimed in against the administration). Bovino was removed from Minnesota and demoted, resulting in him either deciding or being forced to retire. They sent Tom Homan in, and the first thing he did was withdraw half of the agents assigned there, and most of the rest have returned to their assigned jurisdictions. Noem's constant bluster and media presence have sidelined her in the administration, destroyed almost any chance of a political future and cast a permanent pall over the brutal enforcement actions under her watch. Her replacement, Markwayne Mullin, isn't much better in terms of policy goals, but he has said that he doesn't like and doesn't want the constant press from extreme actions. The GOP, including Trump, is being forced to negotiate on things in the DHS budget bill that Trump declared just a couple of weeks ago were nonnegotiable. Trump's actions in Iran have backfired, and so far, the only negotiations happening seem to be in his own imagination, leaving him looking even worse, even among his own supporters.

They're weak and they know it, and their support isn't as solid as it was a year ago. Whether this means they continue to back down or they suddenly lash out, I don't know. But if they do move to mass violence, it isn't going to be against a group of unarmed pansies entirely incapable of shooting back. I hope it doesn't come to that, because it will become impossible to predict the outcome.

Trump has issued 101 pardons in his first 13 months of office, many of whom were very obviously guilty of serious crimes and for which Trump was expecting a quid pro quo. The Cuellars are a prime example. The evidence against them was overwhelming, yet Trump pardoned them and then got angry that he registered to run as a Democrat for office in his district. And there's Changpeng Zhao, whom Trump didn't know anything about but pardoned on the idea that his prosecution was a "Biden witch hunt." We're supposed to ignore that Peng's company made the Trump family $2 billion richer a few months before.
