Plants (even at their puny 2% efficiency) can utilize only a fraction of a full day's insolation; they are limited by other factors.

Thus, there is no need to put solar panels in faraway deserts. Putting them above other land uses -- parking lots, buildings, reservoirs, pastures, cropland -- nearer to use reduces transmission costs. Shading reservoirs, pastures and crops also reduces evaporation, thus saving water. Where water is a limiting factor, partial shade increases yield. Where water is not the limiting factor, reducing water use cuts salt fouling, and enables other uses for the water, including restoring natural habitat.

There is absolutely no shortage of land suitable for solar arrays. You mostly see them on dedicated land (besides roofs) just because that is still cheaper.

"Much as I like hard and realistic science fiction I feel the most impactful science fiction is one that is a lens with which to examine humanity."

This might be a controversial view, but I would argue all storytelling is ultimately an exercise in examining yourself and the context you live in.

Whether the author is aware that that is what they are doing is another matter...
Well, yeah. It depends on what activity you want to do.

I prefer spending time thinking about shapes, design and trying to model them. I suck at it. But I am getting better.
Materialize (https://materialize.com/) is capable of performing SQL operations over a stream, using incremental calculation based on differential dataflow.

CockroachDB is a distributed SQL database, with strong consistency. I think that Yugabyte is similar.

Support for realtime changes, including queries over those changes, is better in other databases, like RethinkDB, OVSDB or Firebase.

Relational is not always the best way to store your data. Sometimes a graph model is better. Or for full text search something specialized is better. In that sense dgraph or elastic search may be better OLTP databases in some cases.

Columnar storage, like used in Vertical or BigQuery have several advantages in processing and data compression. But implementing it in PG or MySQL I think that would require almost a full rewrite.
I found "The Simple Path to Wealth" by JL Collins to be very approachable, and is more focused on overall Financial Literacy instead of just investment advice. It's definitely my first recommendation for people who have very little finance background.

I keep hearing how great are Zerotier and Tailscale are, but from internet networking point of view it seems that are they not just encrypted overlay/underlay networks?

My questions are that, can we implement the similar using purely standardize protocols and provide a GPL alternative? Since this can work globally think this is like Linux but for the internet. Personally I'm a big believer of local-first software and me think it's the future [1], and these Global Area Networking (GAN) protocol will be the building blocks and enabler for that goal. This should be easy and autonomous like normal Web technology where you can use it as it is even there is no company supporting it, but of course you still need internet service provider (ISP).

I believe many of the building blocks are already existed for example zero trust architecture initiative for security and encryption [1], and GENEVE [2] for the networking. Once IPv6 take over the world (whenever this will be) this should be even more straightforward but IPv4 based networks should be feasible. For better delay and latency we can replace TCP with Homa protocol recently proposed by Ousterhout [3], while it's designed for data center it should be better for this type of GAN based local-first software application. Or perhaps a better version of global scale Homa type protocol will be in order.

I’m not following what you say about the weight.

You know what is heavy and relatively cheap? Steel. Yet we ship it all around.

A Tesla S battery is reported to weight 544kg and costs an estimated 15000 USD. That gives us 0.04 kg/USD.

For steel one estimate gives us that 1000kg goes for 1100 USD. Which gives us 0.9 kg/USD.

I thought maybe i’m missing your point so I did the same calculation for something light and expensive we are shipping around too.

One can buy 0.49kg ipad for 440 USD. Which gives us 0.001 kg/USD.

So batteries are somewhere between steel and ipads in terms of kg/$. Can you explain what makes both of those ends shipable while batteries won’t be?

I recall a young man building a portion of the 'Game Of Thrones' theme video. Think watching a real-life mechanical, clockwork Winterfell or Kings Landing twisting and rising all out of pop-up flatwood in your spare bedroom.

Based on Hoffman's theory the reason there is consistency in how the world is viewed and experienced across tribes is because we are born with similar gear - something akin to a built in VR headset. Hoffman gives several examples in the book of objects we create on the fly that are not really there - we call them visual illusions - based on our unconscious visual intelligence logic rules.

Better consistency and transaction isolation models. The ANSI transaction isolation levels are ambiguous and confusing, and the different consistency models supported by NoSQL databases are often poorly-specified. A database with clearer abstractions around consistency and isolation would be a big win for applications where correctness and scalability are both high priorities.
Universities are funded to a large extent by international students. Scaring such students away will create a potentially large funding shortfall.
I see. I don't know of a great answer, but it comes down to the constant speed of light. The simplest clock is two parallel mirrors with light bouncing back and forth. If someone is moving, then the light seems to take longer to bounce between them, so their clock appears slower. Wiki has a a good explanation:

https://en.wikipedia.org/wiki/Time_dilation#Simple_inference

In the hypothetical party scenario, you could demonstrate with your hands or some objects as mirrors.

Not the most satisfying answer, but if relativity was super intuitive, I probably wouldn't have written this book :)
What's interesting is maybe the different incentive structures. I don't know how Derek is doing it, but Wendover seems like to get the funding mainly from Nebula/other sources. In the case of Vsauce, YouTube Red probably has agreements to let outside people manage it to be more "commercially-safe".
Under-rated comment (I'm banned from modding). Technical experts can be trusted for information about cause and effect. They have no expertise about people, of compromise, of other goals people have, etc. This is a leadership task, ideally a coming from a good politician, limited by a good constitution. We seem to pretend that scientific statements about causality are the same thing as government policy instruction. They are not, technocracy serves nobody.

No, it is not hard to get social security. It is also not hard to get an apartment. It might be hard for you to get an apartment in an area that is in high demand.

You should not demand easier social security from society and then be so quick to call those exact civil servants handing it out parasites.

I like the Linux nativeness.

We used System76 at a startup I worked at several years ago. Out of the three systems we purchased, 2 had major problems. One had a problem with the graphics chip so we couldn't use an external monitor, the other had a problem with the SSD or the SSD interface circuitry. The problems took forever to fix.

That was the last time we purchased from them.
The problem is that engaging in "potentially dangerous activities" includes such a wide range of people. Think about a journalist in Afghanistan, a whisteblower in the USA, or a human rights activist in China. They're all engaging in potentially dangerous activities. Are they "dumb" because they don't understand all the ins and outs of surveillance? How about some empathy for them as users?

The proposed statement above is intended to help people like that.

Do I have such activities? Nope. But I believe that those activities should be enabled, whether for me in the future or others around the world.

I advocate on behalf such "dumb" people by supporting simple services like Protonmail with my money. If Protonmail isn't supporting these users, why should I bother supporting Protonmail?
Can you paraphrase it?
Eating fewer calories is not happening in a vacuum. It means giving up food, which is, broadly speaking, the joy of life for many people. Exercising means committing to spend time in an environment and doing an activity that many do not like at all——it thus means going against their desires for months, years etc.

I love food. Wouldn't give it up for the world. I can also tolerate not eating anything for two days very well. It's not really going against my desire.

Ditto for exercise. The hard part is actually starting. Once you start, everything becomes easier.
I think it's very simple. America has learned to live with Covid and this is the new normal: 300,000+ deaths per year, dramatically lower life expectancy, and a drag on the consumer economy.

Another possible solution: if the mode change is not unanimous, ask the pilots!

I hate this meme. It's false.

Nacchio simply tried to use it as an excuse. He was just throwing shit against the wall and hoping that some of it stuck. Here's his claim: he was not in a rightful state of mind when he sold his shares because of problems with his son, and the imminent announcement of a number of government contracts.

Yeah sure, I know exactly what he means. Whenever I'm not in a "rightful state of mind" the way I cope with it is to dump company stock that I'm restricted from selling. /s

Nacchio was nothing but a greedy scumbag, and he went to Federal prison because of it.

If you're not there for financial reasons, then clearly you should not be benefiting from social housing. You are making it more scarce for people who actually need it, by holding onto it.

The tax your landlord will pay on their profits, once you move out to a market-priced property, will be adding to the pot for poorer households to benefit from.
Yeah I think default features resolve a fair bit of the pain. I wonder though how many consumers are actually going to go through the hassle of slicing just what they need out of a library. For something as large and featureful as Tokio it makes sense, or for optional additions to core functionality, but we at least haven’t yet found ourselves going around and looking for places to trim the fat. One dependency like diesel or something similar eats up easily 10x the compile time of any other single dependency, so we’ve been more focused on rooting out those big offenders when we can. I definitely wouldn’t want to ask that OSS maintainers take on extra maintenance burden unless there’s a good reason.

Features are super neat, but it’s easy to see them overused. It’s also a bit hard to adequately test arbitrary combinations of features. It’s a different concern from a library, but we saw this with one of our applications. We had a situation where we were using features where we should have just been using env vars for feature flagging, and it caused a fair bit of hassle. We’ve since ripped out that usage, because we never in practice tested or deployed with anything other than “all features,” and even in the case where we want to use some functionality to upsell, enabling an env var and restarting is way easier than recompiling the project.
There was a story about people using horse grade ivermectin and overdosing. However the "horse dewormer" label is being used to talk about medically prescribed Ivermectin as well like in the case of Joe Rogan or the woman suing the hospital to have Ivermectin administered to her comatose husband. If a doctor wants to prescribe Ivermectin alongside with Regeneron then there's nothing to make a big deal about from a medical perspective.
South Korea never aimed at elimination, important distinction. They aimed to keep circulation low.

Australia’s NSW also did not aim to eliminate. Other australian states do, and have their borders closed to NSW. Complicated story down there. Victoria

China has beaten the delta wave, down to 26 cases a day from 100. I expect they’ll hit zero. New Zealand on the same track, as is Taiwan.

The Atlantic region of Canada was another example.

Vietname I’ll admit has now failed. Not sure if they changed policies or simply couldn’t do it now with Delta.

Then there are some caribbean islands. And that’s about the full list of countries worldwide that did try for zero. Every other country aimed for mitigation.

Granted that not all art is for all people.

What I mean is perhaps best summarised as 'reading and writing are both easy, but a good job of either is preceded by understanding, which is hard'.

So Terraform manages to become the recommended DevOps tool for most cloud providers and now they won't even accept PRs to improve and add features from the community? I think there are greater issues here, first that we centralized around so few major providers instead of improving tooling to scale to any hosting provider and 2 that we let hosting providers create so much abstraction that each one requires an entirely different provider API. Clouds should be as simple as renting VMs or dedicated servers from hosting providers and having an image that automatically brings everything up for you.
Summary: What to say when you talk to yourself by Dr. Shad Helmstetter
> Mnesia isn't SQL-compatible,

I think this is accurate. There are some references to a masters project to do SQL with mnesia, but afaik, it's not supported or used by anyone.

> can't scale horizontally (each node has a full copy of the DB + writes hit all nodes),

This isn't accurate, each table (or fragment, if you use mnesia_frag) can have a different node list; the schema table does need to be on all the nodes, but hopefully doesn't have a lot of updates (if it does need a lot of updates, probably figure something else out)

> needs external intervention to recover from netsplits,

This is true; but splits and joijs are hookable, so you can do whatever you think is right. I think the OTP/Ericsson team uses mnesia in a pretty limited setting of redundant nodes in the same chasis, so netsplit is pretty catastrophic and they don't handle it. Different teams and tables have different needs, but it would probably be nice to have good options to choose from. There's also no built-in concept of logging changes for a split node to replay later, which makes it harder to do the right thing, even if you only did quorum writes.

> and expects a static cluster.

It's certainly easier to use with a static cluster, especially since schema changes can be slow[1], but you can automate schema changes to match your cluster changes. Depending on how dynamic your cluster is, it might be appropriate to have a static config defined based on 'virtual' node names, so TableX is on db101, but db101 is a name that could be applied to different physical nodes depending on whatever (but hopefully only one node at a time or you'll have a lot of confusion).

[1] The schema changes themselves are generally not actually slow, especially if it's just saying which node gets a copy, ignoring the part where the node actually gets the copy which could take a while for large enough tables or slow enough networks; it's that mnesia won't change the schema until all of the nodes are not currently doing a 'table dump' where up to date tables are written to disk so table change logs on disk can be cleared and those dumps can take a while to complete and any pending schema operations need to wait.
