Ah ha, thank you! I was indeed under the misperception that latent heat was associated only with evaporation/condensation at high-energy boiling points, not at e.g. room temperature for water. Turns out it's fiendishly difficult to find anything on Google or educational materials about phase changes or latent heat that aren't at a boiling (or freezing) point -- no wonder I was never taught it. (Finally found [1].)

But in any case, I finally found them and ran the numbers. The latent heat of water is ~4x that of air, but even on a really hot humid summer day water is only 3% of air by mass, which means in a worst-case common scenario, 11% of energy is going to condensing the water, while 89% is simply cooling the air and (non-condensing) humidity.

So if we round, we can say that a heat pump cooling humid summer air rather than drier winter air uses up to around 10% more energy (since winter air has a bit of humidity too), which means heating/cooling are still roughly the same for most purposes.

Whereas the commenter I was originally replying to seemed to be suggesting cooling takes 3.5x as much energy, which doesn't seem to match summer/winter energy bills at all.

Does that cover it, or is there something else my math is missing? Thanks again.

Is there any indication that some immortal human species would be superior to what we currently are?

My intuition is that it would be worse for said species in the same way goats with no predators are worse for goats in the end (overpopulation followed by rapid consumption of the environment and the collapse).
... or just not open-source code any more. This is the silent, and much worse outcome.
I have a symmetric 10 gbps connection at home. I have an EPYC machine that plays host to a number of virtual machine guests for various tasks. One of them is running opnsense to be my router. It's not fast enough to route at line speed, but it's close enough that I don't care. A consumer router or a pi or something would be far slower, and I would start to care.

Having a tolerably powerful computer doing this means that it's also my web server for several sites, stores local backups and handles offsite backups, acts as my print server, and hosts a Windows virtual machine for using proprietary software (e.g., for my label printers or firmware updates for random widgets like my Lutron light system).

Quiescent appears to be something in the neighborhood of 40 watts. It's not nothing, but it's acceptable, especially for the utility. I don't pay for a VPS because I have the bandwidth and the capacity to self-host everything I want. I spend $8/mo in electricity to run that machine, and that will drop to zero when my solar array and battery become functional.

If the power consumption were 5x worse I would probably not have gone this route.
And what makes the voice in your head can't understand what it says.

There are two parts, at least, to sentience: the observer and the actor. In yogic traditions, "you" are the part that "hears" the voice in your head, not the voice itself. I think this, while it may not necessarily be true of "real" minds, has a lot of utility when it comes to designing artificial ones.

I think general AI is probably going to be lots of individual parts structured around a central observational unit, which then makes preprogrammed higher level decisions on where to distribute inputs and outputs of several external nn, score the results of it's actions, and then use the results for reinforcement and/NEAT or something similar to improve it's central decision making.

This technique of a simple, preprogrammed decision maker given inputs and outputs of stochastic processes is already in use in autonomous navigation (see the GT robotics course on coursera)[1].

The actor doesn't need to understand meaning, the observer assigns meaning to the actions of the actor.

This is spot on. And it shows how the stock market has essentially become a sort of mix between a pyramid scheme and gambling, in which its participants buy stock betting on the price going higher and being able to dump it on someone else in the future to make a profit.
It doesn't mean there is no 'server' component. It's supposed to mean that the devs don't have to worry about the underlying server infrastructure that is running their code. They simply specify the code and the conditions under which it gets executed, and the serverless service takes care of running it.
Hey thanks for posting this!
You are focusing on the wrong aspects of the comparison here. The point is not that GraphQL is dreamy from a developer perspective (as opposed to the api end-user perspective). The popularity just demonstrates that there is a real end-user need for the query to be correctly structured out of the gate instead of being re-combined/nested/etc after it's left the database.

> The original idea of relational databases was that they would be queried directly from the client. With the rise of the web this idea died - SQL is too complex to be easily secured against adversarial input, cache invalidation for SQL queries is too hard, and there is no way to easily spawn background tasks (eg resizing images) or to communicate with the rest of the world (eg sending email). And the SQL language itself was not an appealing target for adding these capabilities.

> So instead we added the 'application layer' - a process written in a reasonable programming language that would live between the database and the client and manage their communication. And we invented ORM to patch over the weaknesses of SQL, especially the lack of compressibility.

> This move was necessary, but costly.

Your complaints are about GraphQL at the application layer, ie, the layer of concern that exists because SQL is inadequate for the burden it's been made to bear.

Imagine if GraphQL added aggregates and support for types besides what JSON limits you to, and it then just sat atop an RDMS like Postgres so that you no longer have to fuck around with it at the application layer to get it going. That would clearly be an improvement, right? Or really, just the ability to implement a language like GraphQL atop the RDMS so you can design your own QL that you don't hate.

Another interesting question regards the brain’s capacity to store memories.

What? Li-ion battery makers are constantly making better batteries. That's why competing technologies often have a hard time getting traction: the front runner is refusing to stop running. And remember, it's not just advances in the battery itself that matter, but advances in the factories that make the batteries. Making the factory more efficient and productive is as important as, if not more important than, making the battery itself better on some metric.

Relational Tables & SQL should be just one storage mechanism for your app.

What if someone told you: build an app, but only use b-trees? Then you start complaining about all the shortcomings of b-trees.

The point is that you have relational tables / SQL, along with many other persistence , storage & indexing mechanisms: distributed hashtables, queues, lists, etc.

All the apps I've worked on have mixed SQL with all of the other data structures with consistent or inconsistent replication among them depending on the use-case.

One way to manage this is a key-value online tier and a relational offline tier, with inconsistent replication online to offline.

SQL & RDMBS are very powerful, but like any tool, limited to the designated use case. Stop trying to make it do everything.

Do graph databases predate relational databases? Do you have a source for that? I thought graph databases were a fairly new thing.

I only recently started working with a graph database (a bit over two years now), and it struck me just how terrible relational databases are at relationships, compared to graph databases. I know nothing about the history of databases, but my impression is that relational DBs are basically an expansion of simpler table-based databases that can also handle relations between different entries, if awkwardly. Graph databases are a much better fit and smoother to work with.

We were vaccinated enough for heard immunity from the original variants. That’s why infections were cratering even in places with no social distancing rules.

Indeed every case is unique. My home lab runs about ~4kw all the time, which end up being about 2.8mWh/month. Here in Oregon that ends up costing $340/month.

You seem overly attached to the label of being an introvert. The whole post is slightly confusing to me in fact.

If you've concluded that other things than increasing social skills are more worthwhile pursuits for you in your life, then that's great. You do you. However, you can't then also complain in the next breath about what your lack of social skills, that you won't spend an effort acquiring, exclude you from.

"Still, many of us live in our ways because we've followed our feelings and sensations." is slightly problematic in my view. The hardest things to change are the one that conflicts with feelings. It doesn't feel good to start exercising it you are overweight for example. Socializing with low social skills and confidence doesn't feel good either. I'd argue that both are worthwhile efforts, even though we need to combat our feelings and fears in order to do it.

Again, if you're totally happy right now that's awesome! Just don't let "I'm an introvert" be your "I'm big-boned" type of excuse for not changing anything if something could be improved by change.

I believe that the current installations use CO2 from a concentrated source like the exhaust of a gas turbine to make things easier.

To put some numbers on it, in the US [1] from February 2020 - March 2021:

• For age 65+, the infection rate was 23% and the hospitalization rate 4.9%.

• For age 5-17, the infection rate was 42% and the hospitalization rate was 0.27%.

Kids 5-17 were actually the group with the highest infection rate, followed closely by 18-49 at 41%, then 50-64 at 31%, and 0-4 tied with 65+ at 23%.

The hospitalization rates strictly went up with age: 0.26% for 0-4, 0.27% for 5-17, 0.98% for 18-49, 2.3% for 50-64, and 4.9% for 65+.

I wonder if we would have done better to keep the schools open the first few months, but as boarding schools until most children have had it. Once nearly all children have had it, school goes fully back to normal.

> A client should use appropriate joins to get the data from the database & then do the transformation

Please don't set up "object joins" against an object/key/value table. It's better to flatten the highly used bits of the json out into the table that hosts the "source json" as a blob in one column. There is a place in our codebase where someone did these "object joins", and it's a nightmare to work with. After about two months, there is a comment in one of the tests I found, "I really regret this pattern now". Now we have enough customer data in that object "kv table" that we can't migrate back to json + select flattened fields without extreme pain.

What I’m trying to point out (maybe I did a bad job!) is that it doesn’t make sense to try to run the numbers of how long it would take to return an investment in purchasing Amazon in profit, considering if returning investment capital in profits was Amazon’s goal they would behave in a profit maximising way rather than a growth maximising way. I just don’t think it’s the right question to ask (how long would it take to pay off buying Amazon from Amazon’s current profit margins) because the answer wouldn’t tell you anything interesting about how to value Amazon.

Apple has this. It's called Boujour sleep proxy, and it allows a always-on device like a Airport or AppleTV to claim the IP address of a sleeping Mac, waking it with a WoL packet when traffic for that device comes in.

You know your phone service provider has that location information in resolution that’s almost as good, right?

The only way to opt out is to turn your phone off (equivalently, leave it at home).

For some people, the fact that google also knows it is no big deal. For some it is. But if you are worried about your whereabouts being leaked, how can you justify using a phone in the first place? Verizon and AT&T are more likely to get hacked than google (or just sell that info outright, which they have done wholesale before)
I don’t see any logical sense in this. I think what you’re implying by “dumbed down” technology is technology that is made easy to use. It doesn’t matter how smart you are, more complex than needed interfaces is always dumb design. If a majority of the users use a tool for a couple use cases, the tool should be designed to make doing those tasks as simple as possible. More obscure tasks will be found by the people who need them when necessary, even if their is a steeper learning curve for doing so. I’d never want my hammer to be harder to use than necessary nor would I want a textbook to teach inefficiently because someone thinks the complexity of presentation will make me learn better (while those 2 things may have a spurious correlation, it is possible to get a better outcome while not making the material more complex).

My main point is that the people who have trouble with the complexities of a tool will have a more likely chance of abandoning the tool or switching to a different tool than learning. The people who can navigate the interface probably aren’t getting dumber for using the simpler interface either.

> I'm not sure why you find it so hard to believe that the Eink group has created 2000 display patents to use against competitors.

I guess it is because I work in the display industry and I've never heard them talked about this way within my industry, conferences, symposiums or other peer group events. I've only seen this here on HN and on Boing Boing and some blogs which referenced an HN post making similar claims. I'll try to give you an analogy. Imagine if someone told you Microsoft group has created 2000 software patents to use against competitors and that they intend to defend theier intellectual property. Would you then believe if I told you Microsoft is blocking progress in the software industry? Because that's what the prior post is claiming.

I am generally happy with Amazon. Most times I can get something from Amazon tomorrow or the next day for a competitive price. I’d say that 97% of my orders are delivered on-time and to-spec. When they’re not, it’s almost never been a hassle to get it fixed.

I had one order last year where I was unhappy with Amazon’s treatment on the issue. They were willing to give my money back without hassle, but that wouldn’t fix my wife’s car’s charging system, so I had to make something work.
