Sometimes things have subtle bugs that it takes a long time to track down. This happens less often when they're well written, but it still does happen. And when it happens, the bug fix is often just one line. It's a frustrating experience, but sometimes still worthwhile.

Also, though, I don't think that needing only 1024 lines of code to wire your system into RabbitMQ is any kind of indictment of the quality of RabbitMQ or of the code being wired into it. It would be even less of an indictment if it was only 128 lines or 16 lines or 1 line. But sometimes you need to grok a whole new paradigm; if you've never worked with AMQP before, you probably aren't going to be able to write those 16 lines in half an hour.

Similar comments apply to other domains with well-developed libraries for them. OpenCV, BLAS, regular expressions, LALR parsers, SQL databases, GNU MathProg, and so on: if you haven't worked with them before, it's probably going to take you a while to learn enough about them to apply them to your problem, and then you're going to produce an extremely small amount of code to actually use them. But that doesn't mean your time learning about them was wasted; quite the contrary.

> if you can manipulate the metric, you should be able to create (or vanish) energy.

No, you can't. That would violate local energy conservation.

The fact that energy conservation is a local property just means that there is no well-defined global energy in a general spacetime (though there is one in some special classes of spacetimes). It does not mean that stress-energy can be created or destroyed.

> with a subluminal warp drive, you could hoist matter out of a gravity well and let it fall down afterwards.

But the hoisting process would require you to expend at least as much energy as you would be able to collect from the falling down afterwards.
I think its a good start. Not a lawyer, But my guess is the definition around predictibe systems need to be defined by courts. If a system just collects and curates, but then is fully firewalled from the transforming or learning module, is that part of predictive systems? Its a fascinating start and I will be observing its adaption.
Many things could be "abused pretty easily"

but are they actually abused?
Another interesting term not mentioned is 'qual', which basically has same meaning as 'restrictions'.
I can't think of anyway on the spot of how this could be abused. They still don't know who you voted for, just that you voted. Are there any common abuses of this data?
The voting system is a complicated balance between keeping your individual vote secret and making as much of the process transparent and public as possible. This kind of information being public is likely a check against ballot stuffing.
You are gravely mistaken. MustCompile* if it fails panics at runtime. Go doesn’t have a general purpose compile time execution feature.

That’s all Must does - is make runtime panic look nice.

* MustCompile if you are unfamiliar - the compile refers to the compilation of the regular expression - which is always done at runtime.
In Virginia, the pollbook isn't secret, and technically any observer can challenge anyone showing up and trying to obtain a ballot.

This hasn't happened in my 10yrs of working as an election officer, but still.

I was lucky enough to have taken two FEA classes from Hughes in the 80s. I worked with his DLEARN [1] code many times back then. He was a great teacher.

I never had the pleasure of taking classes from Juan Carlos Simo, but he was known to have outstanding classes. His was a very brilliant light & life cut too short by cancer at the young age of 42.

No, it isn't. You can't "get around" conservation of momentum.

If you're talking about Langley, they money was tragically wasted as the local bicycle mechanics achieved the result mostly by ignoring the theories that turned out to be wrong, and are still wrong, and have been proven to be wrong, and yet are still universally taught today, perhaps as a sort of right of passage, because the truth is either too complex or too simple to fit neatly into the understandability exclusion zone.

> We use DIDs for identity but presently no blockchain DID methods.

I notice that the documentation[0] says:

"We introduced DID Placeholder because we weren't totally satisfied with any of the existing DID methods. ... We cheekily titled the method "Placeholder", because we don't want it to stick around. We're actively hoping to replace it with something less centralized. We expect a method to emerge that fits the bill within the next few years, likely a permissioned DID consortium.

which seems to be an admission that the hard part of distributed social networking isn't actually solved yet, and the project relies on "actively hoping" that a solution will eventually "emerge". I'm also not sure what a "permissioned DID consortium" even is, let alone how it would be useful here.

Anyway, it seems a bit premature to abandon ActivityPub and introduce yet another incompatible social networking silo, based on the hope that the new project's magic placeholder beans eventually grow into a sturdy beanstalk. Perhaps "Beanstalk Social" would therefore be a better name for Jack's project (and he could even keep the same acronym).

Nope, I am opining about what I have seen and heard from people publicly complaining about it over the last few days since the news came out about the change.

For what it’s worth, if Twitter eliminated the blue checkmark entirely…the exact same people would be complaining about that too. It’s their special celebrity badge that separates them as “valid” from the little people.
Had the same idea, tried Valve Index, resolution too low, not good for eyes. However I wonder if you could build a traveling case that includes two monitors like this: https://ibb.co/x2XDYms
Given that that would be opening the manufacturers up to an _extraordinary_ liability if it was ever discovered; that many individuals are highly motivated to discover this behaviour; that it would be possible to do so fairly easily with network monitoring that's well-within the capabilities of many HN readers; and that to the best of my knowledge no-one has ever made such a claim - that's an extraordinary claim that requires extraordinary evidence. If it is pretty well-established, you won't have any trouble providing an example?

You may be confusing this with the fact that recordings are transcribed to improve accuracy[0]. That's well-known and acknowledged! And for folks who _never_ want anyone else to read what they say to voice assistants, that is indeed a problem. But, again - the overwhelming weight of evidence suggests that the only data that is actually transmitted by these devices is when it believes[1] it has cause to do so. I have never seen one iota of evidence to suggest that smart speakers are designed to listen-and-transmit at times other than when there is a reasonable expectation that customers want them to do so.

[0] https://www.rd.com/article/is-alexa-really-always-listening/, "What are the privacy concerns", for instance

[1] yes, false-wakes happen. That's also an issue. But it doesn't support your claim of intentional ("randomly" - I'm assuming you mean this colloquially for "with no justification", rather than literally "in an unpredictable fashion") transmission.

EDIT: to be clear - I absolutely support people's discomfort with these listening devices. If you don't want companies to gather data about you, that's a sensible position to take! If you don't want to take the risk of false-wakes, good for you! But it's important to make the decision based on _actual fact_ rather than scare-mongering, or claims of "well it might" when weight of evidence _and_ active network monitoring strongly suggest that, no, in fact, it doesn't.
Haha yeah not my design and personal choice. But it’s really supposed to be “infinite scroll for the first 3 pages of results than see more button”.
I understand the business decisions into implementing “infinite” scroll, though, and at the very least it’s an interesting problem to take on. Compared to “make this button bigger”

GC is not just for memory leaks, but memory safety in general. It also enables several paradigms that are extremely difficult to get right without memory safety.

In order to have a proper comparison, you should control for variables that are irrelevant to the experiment. In this case, you want to look at the effect of typing, so you should control for GC. Which is why you should compare python to other GC'd static languages, but not to static non-GC'd languages.
Yeah the "superset" perspective seems like you could end up cheating, implementing the equivalent of classical logic and probably much more slowly than a classical computer could do it.

I googled around and found this research though, which does propose using a nonlinear quantum system: https://arxiv.org/abs/2210.17460. It doesn't really claim the issue is solved.
Then there’s only one possible choice: SimulaVR

It’s a stand alone full system though
This, and why isn't there any fiberglass construction? Since most of the build isn't structural, you could use cheap insulation foam for the core (with epoxy resin, not polyester).

Fiberglass is quite easy to DIY and requires almost no tools, and no power tools. Most parts can be shipped in normal sized boxes, aside from the fabric. Whereas long tubes of 8020 need to be shipped via special handling. The fabric can be obtained locally from many hardware stores.
I'm talking more about instance operators. Using an email analogy it's more like running an equivalent of gmail/yahoo mail/fastmail. There's this second order of magnitude on the problem because you're responsible for all of the touch points on all of your users in aggregate. Spam lists and block lists on the fediverse are a thing, but they're just step one of a marathon battle against fediverse spam/illicit content. Most instances are very scrappy operations and spam/block lists only put a dent in a very large and often overwhelming issue.

Working dynamic spam/block list solutions at scale that are capable enough to actually erase the issue are a hand wavey future potential solution, whereas the tidal wave of content exceeding the ability of instance owners to moderate is a very real very today problem.

I think what's actually happening on the ground is instance owners slap on some instance block list of the worst offenders and turn a blind eye hoping there's nothing too bad hidden in the mountain of media they have cached, or they just hope nobody starts caring enough to look. That might work fine for a while but I don't think this problem is going away.

They are all wrong. Historically they've overpredicted warming, and then the models are updated to fit the (new) data better. They perform worse in areas with less data, like polar regions.

To forestall knee-jerk downvotes: I'm not saying climate change isn't real or that anthropogenic global warming doesn't exist. I'm saying the models are not yet developed enough to predict very accurately. Early heliocentric models made poor predictions too because they assumed circular rather than elliptical orbits, they were still more "right" than geocentric models.

> since without government, there's nobody to stop somebody from starting one.

IMO, this is not the actual problem with the practicality of anarchism.

The problem with anarchism is that the absence of government will recreate the problems which motivate the creation of government, just as excessive government creates the motivation for abolition of government.

Particularly, retaliatory (including lethal) violence—not merely proximate individual and mutual self-defense, but individual and mutual action aimed at preventing future threats from past malefactors, is the common anarchist solution to the problem of perceived-as-unjustified use of force (what, in the context of government, would be “crime”).

But we have plenty of experience with that approach ib areas with no accepted government, weak government, or disinterested government, and what tends to happen is that differences of opinion over whether the initial violence was unjustified (or even if it factually occurred) or the retaliation disproportional (and thus itself unjustified violence) devolve into cyclical violence, the relief for which is establishment of a mechanism for settling disputes about justification and thus either legitimizing or delegitimizing and authorizing corrective responses to force, creating the monopoly on legitimate use of force which, whether called a government or not, defines the state.
Could be a guess. I got similar message and it was incorrect.
Sure it can. For example, if we look at the sport for which we are arguably most evolved for - endurance running - then the simple addition of a bicycle improves the efficiency way, way beyond anything we or any animal can achieve.
Internet2 is just the academic peering network and backbone. I general it used fiber leased from commercial providers, so in no way is faster or "better" than what you get outside it.
The argument is a case of begging the question: Start with your conclusion, then reason backwards to the justification.

It's the case that a federation tends to erode. Likewise, it's the case that a centralized system tends to collapse.

The question to ask is really one of backing a horse to ride on to be pragmatically useful; winning the technical argument is academic.

The fediverse has a few core principles in mind, and they tend to get centered in Mastodon's marketing. So it does make some sense that it gets attacked for being an imperfect realization of those principles, and for being unprincipled in other respects. But in a head-to-head comparison with other implementations of social media it can still claim to be more principled on those things it tried to pursue.
My point is that, in that scenario, what replaces the swashplate is mostly the electric or hydraulic actuators, not the MCU. If it wasn't, you'd make the swashplate mechanism much smaller, lighter, and cheaper, even if you had reliability requirements your MCU couldn't meet.

In the north-pointing chariot or the Antikythera mechanism, the differential performed a computational function, with its action of transmitting power quite peripheral to that; in your car's rear end, it performs a power-transmission function, with its action of computation quite peripheral to that.

The same situation holds with transistors. You can use a 2N7000 to toggle a light or control a relay or a motor, or you can use it for (digital or analog) computation.

If you're using it in an NMOS NOT gate or the input stage of an op-amp, you're using it for computation, and so you wish it were smaller; it would work better if it were smaller because then it wouldn't need so much energy to turn it on or off. (For analog computation, you only wish it were smaller up to a point, because at extremely small sizes that makes it more sensitive to noise, but you wish it were really a lot smaller than a 2N7000.) A 2N5457 is generally better for an amplifier input stage, and the no-longer-available discrete signal MOSFETs are probably better for NMOS NOT gates. The N-MOSFETs integrated into a chip are enormously better at computation than a 2N7000.

By the same token, though, a 2N5457 or signal MOSFET is much worse than a 2N7000 at power transmission. If you're using it to PWM a motor, you wish it were larger; it would work better if it were larger because then it would be at less risk of overheating, be more efficient at a given current level, and be able to control a bigger motor. An IRF630 is a better power MOSFET than a 2N7000; an IRF540N is better still. But they're enormously worse at computation than a 2N7000.

Helicopter swashplates and differentials are very much on the power-transmission end of the spectrum, not the computation end, even though they cannot avoid doing computation as part of their job.
Sure, but computer chips are probably the most complicated things that our civilization can currently make.

Asking somebody to prove that a computer won't do X is a fool's errand, outside of some shrinking safety-critical industries.

OTOH a new construction multifamily apartment will probably have a lot of smoke detectors hooked up to the fire dept and sprinklers, regular inspections by the fire dept too, extinguishers and hand operated alarms, sometimes emergency ladders, while most single family homes just have that battery operated smoke alarm that will only beep, if anything at all for that matter. You pass out with a cigarette in a single family home and you are probably dying, at least with an apartment theres a chance a neighbor walking past your door smells it.
I've used it for months and I still couldn't tell you exactly how it works. Open efforts like Mastodon desperately need simple infographics to explain the service to newcomers or you'll end up with a bunch of ex-twatter users signing up, using it for 5 minutes, being annoyed that it's not nearly as simple as twatter and then idling their accounts while they switch to something else.
