Cool progress on a new model organism and toolbox for behavioral analysis. The main advantage appears to be the spatial separation of neurons. (I have not yet read the paper in Cell.)

As to the “mind” of a jellyfish, mouse, or human: much of the core computational activity is molecular, synaptic, and electrotonic—and is not associated with large membrane voltage swings. These lower tiers of processing are orders of magnitude faster and smaller than the network activity patterns linked to behavior.

It is great to understand crude input-output relations—now at neuronal network level dynamics. But how is this much different than what we know about spinal cord circuitry for reflex control in mammals or cortical-cerebellar control of movement initiation and control. Is it fundamentally a better system or is it simply more colorful, “elegant”, and semi-real time? IMHO; the latter.

Not sure these are quite the right metaphors, but imagine trying to understand microprocessor function from either just input and output relations or from timelapse data on CPU transistor currents—but only every few milliseconds.

To understand neuronal computation we must, at a minimum, record synaptic and membrane currents across cells and circuits at the 0.1 millisecond levels over minutes and hours. And preferably across many environmental perturbations (see Ev Marder’s amazing work on the shocking complexity of somatogastric ganglia of crustaceans.)

And to understand the true sources of behavioral variation in a causally rigorous way we will also need gentle genetic perturbation generated by natural DNA variants—not knockouts on one genetic background—that is a misdirected focus of so much reductionist N=1 neuroscience.
It isn't, https://www.solidjs.com/guide#react is kinda nice read
What kind of sanctions do you have in mind?
Thanks for the clarifications on your first two points. On the last:

You are using very wavy forms of utility. How do you define utility? I was thinking on the utility of the individual, asking about whether something like getting lost in gambling addiction after someone caught you in their funnel is truly positive utility because you "want" it.

In the same vein as your 2nd point, I'm also gonna guess you are more of a libertarian/minarchich bent because of this because while in my experience statist tend to oversimplify and wishful-think the impact of the state and anarchists tend to oversimplify and wishful-think the willingness and ableness of a group to self-organise in an anarchist way, libertarians in the US style/minarchists tend to oversimplify the question of self determinism and have inconsistent thought on what exactly the role of the state should be (it should exist because otherwise you can't have private property, but everything else...) and don't consistently acknowledge predatory behaviour that preys on human vices exists and works (AGAIN: I don't want to police the vices, I want to curtail profits on it. Self-organised vices without additional motivators are fine with me).

I also find it interesting that you claim you think term of utility and externality on collective action problems but then don't consider price of action - we don't lose anything big with crypto right now, but we would gain at least a finlands worth of energy to blow on other things ( https://www.nytimes.com/interactive/2021/09/03/climate/bitco... ).
Sorry if I came off as rude, because that was not the intention.

I'm a freelancer, and my best friend is an employee (both developers). He knows I earn a lot more money, but he explicitly chooses to stay as employee. Why? Because all of the things that you mention.

Plus, when he goes home, he spends time with his family and hobbies. For me, my company is always there. Still need to do administration, see which things I can write off, etc.

I used to think everyone would be like me, once they know how companies really work. But that is not the case. I'm pretty sure everyone knows what they can expect from the company, after a few years in the workforce.

So I definitely don't consider your choice as wrong. It's really about which things you prefer in life.
Doctors' groups have consistently lobbied against it because they fear it will reduce their power and earning potential. That's the most influential lobby. The AMA killed Truman's national health plan and lobbied hard against Medicare.
There are several misconceptions (as pointed by others) relating the trade-off of electrical vs optical for interconnects. Optical interconnect are promising, and in fact, at some point they will become almost unavoidable: bandwidth vs path length. If you want to dive into the fundamental reasons, the following paper might help: https://www.researchgate.net/publication/224504016_Miller_D_...
I've had this same thought.

Dumb thought...DD-WRT for TVs?
Good point about isolation and noise.

I got the propagation numbers from Wikipedia:

> the refractive index of glass is typically around 1.5, meaning that light in glass travels at c / 1.5 ≈ 200000 km/s [0]

> the refractive index of air for visible light is about 1.0003 [0]

> Wires have an approximate propagation delay of 1 ns for every 6 inches (15 cm) of length. [1]

The speed of light in air is c/1.0003, or 299,700 km/s. In glass, it is c/1.5, or 200,000 km/s. If Wikipedia is correct, wire propagation delay is about 15 cm/ns, or 150,000 km/s, which is still slower than in glass. If that number is off, would you please update the Wikipedia article with the correct number? It would be good to include a better reference than the university textbook it currently cites.

Also, I don't think we should assume that a future processor optical mesh will carry signals in glass. I expect it will use micro-randomized mirrors and protect the optics with inert gas. The randomized mirrors will form random optical lines between cores, on the same chip or between chips. The lines will spontaneously reconfigure due to mechanical shock or changes in temperature. The OS will detect such changes and automatically reconfigure the software to optimally utilize the current connections. This should allow hot-swapping CPU cores, and upgrading or downgrading processors on live computers.

There is a scene in the film 2001 Space Odyssey where (MOVIE SPOILER) the protagonist removes pieces of a computer and the AI running on it becomes slower and slower. Such a thing may actually happen.

> It's also very possible that transactions fees alone actually will be sufficient to support a high enough amount of hash power to secure the network.

I have to admit that I have no idea how much work is actually needed to secure the network. My point of view is that the current rate of energy expenditure outweighs whatever benefit Bitcoin does or could provide to society. But if this rate is a transient result of still-significant minting going on, things could definitely look different in the future.

Do you know of any analyses on how much work really has to be continuously expended in order for Bitcoin to remain reasonably secure at a given market capitalization?
Unfortunately it looks like this is either voluntary clickbait, or the author doesn't understand either the technology, or the world.

FWIW dang was extremely helpful when I had an issue. He worked with me to resolve it, rather than take arbitrary executive action. I don’t credit any accusation of dang playing favourites to YC founders. Basically, there is no level of assistance higher than what I received, therefore there is no way someone is getting preferential treatment. There’s simply no more that could’ve been done.

Note: I wasn’t completely happy with the outcome at the time, but I respected the decision. I hindsight I agree with it too.

The JA37 Viggen is probably one of the few planes that managed to get a missile lock on the SR-71. This was mainly to try to push the northern flight path (over Norway, then onwards over Russia) to pass north of Sweden, instead of crossing Sweden. Take a route of JA37, ascending on full afterburner at about 45 degrees, coordinating with fighter control (military ATC, also trained to assist fighters during air-to-air combat), so as to enable the missile targeting systems when the SR-71 would be in an optimal position in the cone.

Most probably, the SR-71 would've been safe even if the missiles had been fired, but the goal was never to take it down, just to make them shift the overflight pattern to no longer be in Swedish airspace.
I don't know if there are any updates on this specifically but, "decentralized internet standard, like SMTP" sounds an awful lot like ActivityPub.
> What’s not great is loading the entire closure VM environment into my browser

There's no VM in clojurescript, it compiles to JS, it is tree-shaken and heavily optimized and minified through Google's Closure compiler.

> resulting in the software running (in this case) 50x slower

The speedup is not a result of abandoning clojurescript, it's from moving from immutable data structures to mutable arrays and primitives. The same can be done in clojurescript or javascript.

I think this is a common misunderstanding, that's why I'm reacting. Nobody claims immutable data structures to be the silver bullet. Computation-heavy parts need to be done in low level code and with primitive types.

I don't understand how an NFT helps with legal enforcement?

Even if every big platform has some magic pixi dust ai that knows every nft in the world and checks against it.

What about illegal streaming websites? or any other type of content.
Without going into stuff like Kubernetes, basically what you want is to run your postgres instances behind a load-balancer listening to 5432 and forwarding to whatever instance. The most common with postgres is probably HAProxy.

If your problem is that you want to run unrelated instance of postgres... you don't really have a problem to begin with. Either use docker run to run your postgres image on different ports with different volumes, or just make a docker-compose YAML file with a bunch of postgres services. It's not like you have to have a single one.

> Because they market to folk who never take the time to model comparative costs. In any project I considered them for (3 I think, <$15k/year each), Digital Ocean was significantly more expensive than AWS. I follow my spreadsheets, the industry follows marketing.

You make valid points, but what you're missing is the same accusations you level at Cloudflare were once leveled at AWS (which is why AWS had virtually no credible competition from Y!, MSFT, GOOG for 7 years!).

Also, Cloudflare's moat isn't 0ms cold-starts, but their persistence in commoditising bandwidth. Think Amazon Prime free 2-day shipping and how that worked out...
This is the money quote:

"NFTs need standard, legally enforceable licenses. In the same way open source and creative commons are underpinned by the law, NFT-based licences should be underpinned by a legal foundation. Developing and issuing standard licenses for NFTs shouldn’t be particularly difficult and both platforms like OpenSea and artist groups should collaborate to release these licenses as soon as possible."

NFTs--as a technology--have absolutely nothing to do with what the author is proposing. What's really proposed here is to replace intellectual property law--which, to be sure, has flaws, but which is the result of a public, democratic process--with private contracts and licensing.

Nevermind that creating legally enforceable licenses which transfer with the change in ownership of an NFT is quite probably (legally) difficult; were it to be done, we would have successfully replaced an area of public law with private contracts in which--as with private arbitration agreements supplanting public courts--the powerful and the lawyered win out.

"Web3.0" is so much bullshit, of course, but this is one of the more egregious cases of masking a lawyer-heavy play to empower the already empowered as "revolutionary technology".

This is correct. Daily street commuters can expect to get hit. I took some observational statistics at the place where I started commuting, and there were about 20 people that biked to work every day, and one got killed on average every 2 years, mostly on a single 400m stretch of busy road running to the building entrance.

The main feature that increases safety seems to be overt bike lane and shoulder markings. So push for those if you have any involvement with local government. Our problem was the snow plows grinding down the paint, so some drivers would do things like try to pass on the right as if it was a multi-lane road. They will not notice a cyclist at all when doing something like that. I've also been hit by red light racers. They are only looking at the light, zero awareness of anything else.

The best thing you can do is probably to just run the brightest flashers you can at all times, front, back, and sides. And this sounds silly, but, think about what you are going to do if something goes wrong. My worst hit was greatly mitigated by just remaining calm and reacting as I had rehearsed in my head, rolling up onto the windshield and tucking into a ball as I flipped through the air. One thing I wasn't quite ready for what what it feels like to get hit by a wall of steel at that speed, nothing like what happens at normal human speeds like playing football.
This comment is completely off: obviously asciinema didn't store each individual pixel in its data structure. That would be a completely stupid thing to do even for a regular data structure instead of an immutable one…

I love having the context from a good set of liner notes. Session dates, musicians, back story. It anchors the music as work done by real people, and not just content to consume.

I don't really care about the physical discs, but it seems like there's not a lot of options (at least in bluegrass): a lot of this content is just not available digitally. (And when it is, the liner notes are usually lost in the process.)

People who think that are thinking about "all in war, people running with guns everywhere".

Even in WW2 that was not the case, there were huge swats of land where people were living as if there was nothing going on.

US is already at war with China on the trade. There is full blown cyberspace and intelligence war going right now.

So that you are not running twice a day to a shelter does not indicate there is no war.

I'm getting tired of being right every time. I'd love if the vaccine worked and I didn't have to hear about Covid ever again in my life. But obviously that's not going to happen and there isn't a plan for it to happen.

I'd also love if we had ongoing scientific trials in every country where the vaccine is being used with control groups and all those nice things traditional science used to have. But sadly new-science seems to be just politics and marketing, so we just keep surfing click-bait after click-bait article through this pandemic without really going anywhere.

We don't even have a decent model of the seasonality of Covid, because seasonality is very useful politically to pretend measures are working.

I agree with your sentiment. I would fine tune the wording too:

'Forgiving loans people take out for an activity, would lead to more demand and greater price appreciation of that activity.'

I think the great harm was disconnecting students from the immediate consequences of their educational spending with easy to get loans.

That economic disconnect has made it ever easier for schools to charge more for less actual value. Whether in poorly directed education (exceptional education in areas with poor career potential), or simply over priced (top heavy admins, and other overhead or expenses beyond providing actual education).
HN as a platform is effectively dedicated to a narrow set of topics, with a largely homogeneous user base (compared to any mainstream social media at least). I don’t think the consensus here is particularly favourable towards free speech, and it certainly has a very narrow Overton Window of acceptable ideas. The user moderation features also heavily reinforce whatever groupthink is popular, you have to “accepted” by accumulating a large amount of karma to influence voting, and 4 in-group users disagreeing with a comment is enough to remove it from the discussion.

I think Dang’s moderation is usually pretty decent, but I really don’t think this is a place where free speech is championed. In any thread on the topic, calls for increased speech regulation seem to be very popular.
The way companies chase short term profit, twenty years is almost certainly an eternity.
Slightly off topic, but I think bike thieves are becoming more and more professional recently. Here in Berlin many now use small cordless screwdrivers with a custom gearing mechanism that operates a bolt-cutter. With that they can even cut through thick steel-bar type bike locks in a few seconds, without making any noise. I saw that in a police report lately but I can't find a link with a photo of the device now, unfortunately. It's really quite ingenious from a technical point of view. It seems the only way to protect against theft is to ride an old bicycle.
Users can only get an update by rebooting their devices, so it absolutely goes against the security argument.

> with a client on your streaming box like Plex, Kodi, Infuse, etc connecting to your server.

Never heard of Infuse but don't Plex and Kodi both contact the vendor's server? That is enough to make me not want to go anywhere near them. I do know there are home media center distros for the RPI and PC and they are supposedly nice. I'd be ok with using one in principle, but I haven't cared that much about media UI to bother. I just use command line mplayer on my laptop if I want to watch a video, and that's good enough for me. I can understand other people wanting a more TV-like experience, which is also fine.
