Well, for starters: https://www.cebm.net/covid-19/what-is-the-evidence-to-suppor...

You'll see that there's no high-quality evidence supporting basically any of it. It's either based on bad data [1], confounded studies, or worse.

...but to be clear, you have to define "social distancing" more specifically. If you define it as "hiding it in your basement to avoid colds", then the answer is going to be different than, say, "standing on spots in the elevator", or (more to my original point) "doing alternate day in-person education because teachers want fewer students in the classroom".

I'd still argue that we need a shred of decent evidence for any of it, but we should at least start by being specific about our claims.

> Social distancing has been a proven method to combat the spread of ilnesses, including respiratory viruses, for centuries. And it still works, and it did work for Covid.

It's pretty funny how you demand sources from other people, but then just make stuff up.

[1] Classic example: asking people if they "social distanced", then asking those same people if they remember getting sick. There are so many "studies" like this in public health "science", and if you exclude them from meta-analysis on the grounds that they're total bullshit, partisans start accusing you of "cherry-picking", because that's often the full extent of the affirmative evidence for whatever thing they're advocating.
Is it? An apple is only ~100 calories. 300 calories. You could make it a full meal by adding 500 calories of chicken or beans/lentils + rice to get to your 800 target and that's a very solid meal. A whole can of tuna in water is only ~200-250 calories and another option to add more protein.

Today I'm using 2x 3090's which are over 4 years old at this point and still very usable. To get 48gb vram I would need 3x 5070ti - still over $2k.

Show HN: CaddyFile Generator
I wanted a tool to make managing my CaddyFiles easier so I created CaddyGen. It has presets for several server tools you may want to reverse proxy, allows you to set up custom hosts, has options for several options, etc. You can import your existing CaddyFile and manage with the tool.

It doesn't send anything to any servers, its all stored locally on your browser. If you don't trust it still, you can grab the source or use docker and self host it.

Made this with bolt.new because I wanted to evaluate the tool (i like it). I'd never have made this as quickly by hand.

It's hard to take an article seriously when they write "was one of the 5% or so that are slow growing and most likely to be cured."

There is no cure for pancreatic cancer. There are people who survive it, but nobody knows why.

> and then went through heroic real-doctor efforts once it was too late:

If it was "too late" why did these "heroic real-doctor" exert any effort? Shouldn't they have known better? Being "heroic" and "real" doctors.

The guy chose to be a lab rat after his 9 months of "alternative medicine" and 5 years of "real medicine" failed him. These "heroic doctors" failed him just like the "unheroic doctors".

As I said, cancer isn't an exact science. People who think it is either know nothing of cancer or are just unthinking bootlickers. Hopefully one day we'll have a cure for cancer.

> A 10% error can be calibrated out if it is constant (in practice it probably varies a bit with temperature).

Unfortunately, Vos on cheaper general purpose OpAmps is the kind of thing that varies by... voltage. Ick.

> For these applications, Vos is one of the first things to look at. Another one is the temperature coefficient on the gain. High frequency noise metrics such as CMRR and PSRR are sometimes important if you're looking at high frequency signals, but most of the time mechanical phenomena don't have much interesting content above a few 100s of Hz, and high frequency PS or CM noise can be removed by a simple high pass filter.

No. CMRR is about DC in the applications I'm talking about. It's weird because CMRR is listed in decibels but it's absolutely a DC spec.

If you have a high side current sense circuit with common-mode voltages of 24V +/- 0.05V (ex: 24V power supply that dips to 23.95V at 5Amps), CMRR tells you how accurate you are here.

Your typical 60db (btw I need to kill the engineer who decided db measures DC noise/errors....) means that the 24V of common mode voltage (which is the 24V DC power supply in this case) leaks into your measurements.

Or in other words: 60db * 24V == 3 decades or 24mV of 'Noise' aka your +/-50mV signal/measurement got completely wiped out by your DC errors. Like 50% error bars on your signal now, good luck with that.

That's the real issue with OpAmps. There's surely an OpAmp out there that solves your problems. But it requires knowing the general tradeoffs and picking-and-choosing different parts for different purposes.

Secondly, the specs are not intuitive. 60db CMRR sounds like a high frequency issue but becomes DC in this case.

You could of course go full isolation (optoisolators) that allows you to shift voltages down to near zero (removing CMRR issues) but that's money and additional parts.

You could go low-side voltage sense but this doesn't work for all circuits (most circuits are fine with Vcc error, not Ground errors). So high side current sense is the most flexible and generic well engineered solution. So long as you choose the correct OpAmps.

-------

As far as when this could be useful: consider Maximum PowerPoint Tracking for solar. 0-24 V and 0-1 Amps. And a need to accurately measure Amps and Volts from this entire range. (A variable load + voltage converter like a switch-mode power supply + battery can search for the optimal Voltage/Current combination to maximize the Solar Panels power).

Yes the microcontroller will do the bulk of the math. But the initial multiplies and subtract is best handled by an OpAmp.
You said it's compatible with hardware from 15 years ago, but one of the examples have the graphical complexity of half-life from about 25 years ago, could this engine be optimized further to run on hardware from that vintage or at least closer to? Would be pretty cool making games that can run on a Ryzen 9950x 32 thread monster but scale all the way down to a 1Ghz Pentium III and a Voodoo 3.
Thats the thing with socal traffic especially. Absolutely zero enforcement by the police. What do they do with their resources instead? There was a man with a knife caught in a burglary last week and the police sent like 40 suvs some unmarked with the blue and red lights through the windscreen, a swat team, and a helicopter. Probably in the millions spent for that operation alone for this guy with a kitchen knife. I wonder how little you could get a man with a knife disarmed for in some midwestern suburb in comparison. Oh and keep in mind they didn’t actually go in after the guy they just did a standoff till 2am when he surrendered on his own.

Meanwhile everyone blocks the box and there are cars without even plates on them.
The middle ground between hyping the new tech and being completely skeptical about it is usually right. New tech is usually not everything it's hyped up to be, but also usually not completely useless or bad for society. It's likely we're not about to usher in the singularity or doom society, but LLMs are useful enough to stick around in various tools. Also it's probably the case that a percentage of they hype is driven by wanting funding.

> Elites the world over are losing in democracies because they presupposed, from afar, that they knew what their constituents wanted

Elites the world over are winning in democracies (take the US for example), which could feed into the hypothesis. Indeed, nonzero voters of these elites were easily bought.
Elites the world over are losing in democracies because they presupposed, from afar, that they knew what their constituents wanted.

... or perhaps because you've misidentified the "elites."

Voters' interests are complex, and they can't be so easily bought.

You're right about there being a lot of similar apps in this space. I think it's evident that the approaches tried so far haven't resonated with people in a meaningful way. And it's very possible my approach is wrong as well. With social apps, the smallest nuance in how it makes people feel can be the deciding factor for whether people use it or not.

I would love to hear more about the challenges you faced as you grew out your previous iterations.

States typically define residency as either based on domicile, or a statute. In other words, some of the states you "traveled" to undoubtedly have laws stating that if you are in the state for a certain number of days out of the year, you are automatically a resident, not a visitor, and liable for taxes on your world-wide income.

> Weight loss programs do not work long term because only healthy nutrition does

That's not entirely true, although it is a big factor. As an anecdotal example, there was a period of my life where nearly 100% of my diet was fast food: there was a McD's, BK, and Wendy's in my neighborhood. I did this part out of laziness, and part because Supersize Me annoyed me. In contrast to Supersize Me I dilligently tracked my caloric intake from those meals and intentionally limited things to be affect the changes I wanted to see in my weight.

Net result? I lost weight until I achieved my target, and then I was able to stay steady.

Would I recommend this plan? No. I was focusing purely on weight and I'm sure there were many other suboptimal knock on effects for my body. But people act like it is physically impossible to lose weight via pure caloric deficit and/or by consuming fast food. That's not true.
E-bikes though?
> Here’s another possible interpretation: our information environment makes people extremely vulnerable to actual bullshit in massive volume

That is also true. People get angry and then misdirect it. But the anger is real, and it filters up through the political system when the valves aren't clogged. They aren't, not anywhere in the West. Voters across the West have essentially begun a wholesale replacement of their stable of elites. That is not what happens in an oligarchic system.
> even if you're not driving in downtown Manhattan, you will still pay the cost to enter the city through the normal entrances

Incorrect--if you take one of those bridges/tunnels below 60th street, then stay on FDR or West Side Highway to travel to a different part of NYC (i.e. you never enter the interior surface streets below 60th), then you don't pay the congestion fee.

"The Congestion Relief Zone includes local streets and avenues in Manhattan south of and including 60 Street, excluding the FDR Drive, West Side Highway/Route 9A, and the Hugh L. Carey Tunnel connections to West Street."

Show HN: Tinyhnsw – The Littlest Vector Database
In an effort to understand it, I put together a simple, pure python implementation of HNSW, an approximate nearest neighbor library. Learned a lot, and I think for anyone interested in vector search it's an exercise that's absolutely worth doing.

There's also working code examples for using the library for text and image search with sentence transformers and CLIP!

Large-scale audio systems will often use synchronous Ethernet or other similar protocols instead of things like TOSLINK at this point.

Also, a general solution to "send low-bandwidth over an SFP" is to use FM or phase modulation to carry the signal on top of a carrier wave that is fast enough for the retimers in question. Buffer and retimer chips will not respect amplitude in a modulation system, but they will largely preserve frequency and phase.

I'm not sure you understand how to capture snapshots at the correct level of granularity. If you have snapshots that are breaking for irrelevant changes, then by definition those changes don't need to be snapshotted, do they?

This snapshot will break if I have a bug in my pagination logic implementation, and it's highly unlikely to fail for random irrelevant changes.
