Hydro storage is a completely different animal than native hydro generation.

A reservoir for the latter requires a river collecting water from a large area watershed, and a dam lower down backing water up the river course.

Hydro storage requires only an elevated basin, and a pipe (penstock) leading up to it from a ready source of water -- even groundwater -- no watershed needed. Such basins are legion, and filling them typically discomfits no one.
I’m ordering a grip of employee laptops to refresh our fleet and expand some departments. Because Teams is such a dog, my #1 requirement is 16GB RAM. Maybe Microsoft _wants_ Teams to be piggy to drive hardware sales?

On another note I think Teams is actually an Electron app? I do think it runs better on my Intel MBP than my new Surface Laptop. But it’s still pretty buggy for such a high profile app.
I don't get what's going on with on-line storage. You can walk in Best Buy and get a few Tb hard drive for well under $100. Yet every cloud service wants to charge you several times that per year for just 1Tb. I understand drives fail, there's operating cost, and some need extremely low latency. But there seems to be a huge disparity between what a hard drive costs, and what it costs to make it available on the Internet.
I love Xcode and wish it offered support for more languages.
Earth and Mars orbit around the sun. Sometimes they're on the same side of the sun, sometimes they're on opposite sides.

Using extra fuel you can make launch windows larger, but they're going to come every 26 months no matter what you do.

I know there’s some serious chicken/egg issue here, and solves a different problem than Google or DDG. but I think what I need is a way to “Like” or “Favorite” a page I’m on (maybe just a bookmark?) and that triggers my personal search indexer which will then index that page.

Then maybe optionally “follow” other people’s favorites as part of your own results. Imagine someone crawling Twitter or SoF and you just “follow” their index and it gets merged with your results and disable/enable them for specific searches.

I’ve been thinking about it a lot lately because I often am trying to remember something that helped me or I wanted to remember. But I can’t find it in my FF history. And Bookmarks feel too clunky.
Businesses are in business to stay in business.

Frequently nobody notices how much decline in capability the team is struggling with because 1) the change comes slowly, and 2) people are getting 'better' at taking calculated risks that keep the tempo up, masking the real situation until the company hits a brick wall and all estimates go from 3 weeks to 3 months overnight.

As a customer these sorts of changes in behavior are hard to accommodate. It's almost always better to set an expectation that things take just a little bit longer than the customer would prefer but the software actually works when we do get it.

When you have a date driven 'emergency' you deliver a small increment that handles the particular situation the customer actually has. Everyone mistakes wants for needs. When you foster that then you become part of a codependent relationship at best, exploitative at worst.

Also if you swoop in and clean up everyone else's mess every time, they never experience any backpressure and you end up burning yourself out while they learn absolutely nothing. See earlier reference to The Power of No.

Agreed. My main problem with Electron apps is just how slow it loads, even on an M1 Mac (~20 seconds loading time vs the normal 1 second or less). Discord is certainly no exception to it, and even steals focus twice while loading.

Personally I have to quit Discord to keep myself from getting distracted, so it’s way worse when you have to wait so long just to reply to a notification.

The amount of helium will be much lesser than what you think it is. If we produce all the energy in the world using fusion, it will create less helium per day than a tank used by kids helium balloon shop.

> If one ton of deuterium were to be consumed through the fusion reaction with tritium, the energy released would be 8.4 × 10^20 joules[1]

That's 0.84 exajoule(233 TWh) per kilo of deuterium or 0.42 exajoule(117 TWh) per kg of helium produced. World energy consumption is 1.6 exajoule per day[2] so less than 4 kg helium will be removed per day if energy extraction is perfect or few 10s of kg assuming imperfection

> B-Trees are notorious for their complexity

Can you tell me more?
The Difference Engine was doing only additions and subtractions. For additions and subtractions, it does not make sense to split the operands in smaller pieces and then chain the results by carry propagation. Or rather it does make sense, but this is exactly how they are implemented to begin with: the operands are split in groups of 1 digit each, and then the operation is done digit by digit, and there's carry from one digit to the next.

The Difference Engine does not do any multiplications.

As for the stupendous precision. I implemented a difference engine today in Excel to see what's going on. It's a very fun exercise, one can do it in 15 min. But be warned, you'll waste hours playing with the thing.

Here's how the Difference Engine works. You want to calculate a function f at the points 0,dx, 2dx, 3dx, etc. You do it inductively, using the formula

f(x + dx) = f(x) + f'(x)dx

But who is going to give you f'(x)? Well, you calculate that inductively too. Or more precisely (this is crucial) you calculate the whole f'(x)dx inductively:

f'(x + dx) dx = f'(x) dx + f''(x) dx^2

And then for f'' dx^2, you say

f''(x + dx) dx^2 = f''(x) dx^2 + f'''(x) dx^3

At some point you decide to stop, so you assume that a certain derivative is constant. That's the order of the scheme. Wikipedia states that the second Difference Engine envisioned by Babbage had an order of 7 and 31 digits of precision, but I suspect it's a mistake. I think it's more likely the order of 8. The 8'th derivative of log(x) evaluated at 1 is -7!=-5040. If you use a dx=0.0001 then you need to store the number 504010^-32 = 504 10^31.

So, I suspect Babbage was trying to produce log tables with increments of 0.0001 with a precision of six digits. If you look at the error of this scheme, you'll see that it grows exponentially, and after just 1000 steps the error is of the order of 10^-6. So you need to reset your starting point, and start again. You produce 1000 more logs, then you reset again. After a while, the scheme becomes better behaved (fundamentally because you move further away from the function's singularity, which is zero). By the time you are around 4, you can run 10000 steps while keeping the error below 10^-6.

Now, it looks like a successor of Babbage, Scheutz, actually built a difference engine. I think the guy deserves as much admiration, if not more, than Babbage himself. He used 15 digits and only 4th order differences. But if you look at engines with different orders, you'll find out that higher orders stop giving a significant bang for the buck after the 4th order.

Does 15 digits/4th order make sense? Well, only if you are quite smart, but I think Scheutz was plenty: the fourth order derivative of log at 1 is 3!=6, so you need to be able to store the number 60.0001^4=610^-16. But how do you do that if you only have 15 digits? Well very simple: you observe that for the first about 1000 steps, all the numbers in the table start with 0.0, so you don't store only the digits after that, and for that you only need 15 digits.

Yeah, I've found this to be the least broken (and fastest) way of joining a meeting.

No issues with any other meeting platform (Slack, Zoom, Discord etc... all work a treat), but the Teams client, on multiple machines? I've lost track of the number of times it's just not worked for me, or been an absolute dog.

Hope that Microsoft give it some love, because it's definitely got room for improvement.
>The amount of people that can afford to pay that is minimal

average American wedding is close to $30K, so i think there is a large market at the top. Plus corporations with their outings/offsite/etc. for S/E/VPs flying business class to nice places, influencers/promotions/raffles, midlife crisis and retired doctors, lawyers, execs as well as tens (if not a hundred) of thousands of young FAANG employees making $500K+/year. It is just that Virgin Galactic and Bezos unfortunately don't do justice to the coming space tourism.

>The logistics and regulatory hurdles are going to be massive

That really hinges on whether Starship will reach airline level of safety which is a huge undertaking and naturally at least several thousand of launches away. Those coming several thousands of launches anyway are planned for bringing into orbit those several millions of tons destined in particular for Mars. I.e. i just don't see any spare capacity from Starship. As far as i see it will be utilized 110%.
Exactly; there is a real problem with doctors just accepting ‘old age’ and stop looking for causes.
Zulip solves the problem you mention extremely well.
I believe it's the same case for anyone that contributes to Wine. I remember a recent case, some old Windows source code was leaked and there was a discussion around this policy.
I purposely stayed away from #1-3, to avoid getting dragged into partisan muck. I would call the situation untenable when the local police are no longer under control of their civilian governments, and I would say at that point the federal police stepping in is entirely appropriate. Part of their actions should include holding the insubordinate and corrupt local police accountable. (Also note I said the easiest thing gets used, not the most authoritarian or extreme)

#4 seems like a decent check on the action, but the action itself is repulsively technocratic - cutting citizens off from the necessary infrastructure of the banking system, by executive decree. And regardless of being heavy handed, it seems ineffectual for actually discouraging the protests and if anything might just increase their resolve.

Soyuz is the only rocket that has flown much more than 100 flights, and it has a reliability of 97%.

Several other rockets, including Falcon 9, have flown enough successful flights that statistically their reliability is unlikely to be less than 99%, but we cannot know that it's any higher than that.

NASA figures that the failure rate of a Dragon flight is about 1 in 500, but that's based on analysis rather than statistics and is likely quite wrong. Note that the highest chance of failure in their analysis is a micrometeorite collision rather than a rocket failure.
There's this fun Japanese crime mystery show called Galileo where a physics prof solves similar 'classic' crime story tropes.

My favorite 'modern' solution to the locked room was, spoilers!, that the door with a large handle to the room appeared locked at the time of the crime because the murderer was using a small hologram to make it appear locked from afar.

In fact, there's a huge literature genre in Japanese fiction: Honkaku, reanimated in the 90s as Shin-Honkaku. Do yourself a pleasure and go read Edogawa Rampo.

Additionally, the "antibody count" is completely ridiculous to use as the primary proxy for immunity. Anyone that knows how the immune system actually works can tell you this. Healthy humans have zero circulating antibodies for most of the viruses that they are already immune to. Otherwise the blood would be filled with them. Cells in the bone marrow are where immune memory resides, and the body manufactures circulating antibodies based on these memory cells.

Self-hosted software has its benefits. But, it's inaccessible to a lot of groups. So, I'm intentionally building more of a managed product. Controlling the deployment end-to-end will allow setting up new features more easily such as inbound email parsing.
> No, investors bought 100% of U.S. homes in 2021.

Clearly that's not true. A lot of people bought homes on the desire to live in them and for their children to have a stable place to grow up.

Investor means someone who bought the house strictly as a means to make money with no other motivation. Like buying a share of stock.

Most individual homebuyers don't view it that way.

A particular flavor of this I've become familiar with over the last few years deals with how you enumerate problems rather than bringing up a single one.

It is, I think, a variant of Burying the Lede where you start out with the serious issue, but then you keep going on and on for so long that eventually everyone forgets that the first point you brought up was "The building is on fire."

Sometimes the lede should go at the end, be repeated at the end, or you should keep your comments to what can fit comfortably into short term memory. No flooding.
Government can easily restrict international sales, just like they did for vaccines (and routinely do for encryption software/hardware and other goods).

I'm in the lead-weight-dragging tail (working in a bank using Teams, but dealt with this at the last job in Slack as well).

> gluconeogenesis

I am very curious about gluconeogenesis. I am well aware of this pathway but have read a few times that glucose generation from protein happens very rarely. Have you ever tried eating zero carb whey protein in a fasted state? If yes, have you noticed a spike in glucose? I am genuinely very interested in your experience with gluconeogenesis as a person with diabetes.
Direct harvesting is not possible with the fusion reactions we are currently working on. The products are electrically neutral, so the only way to harvest the energy is as heat.

Helium-3 fusion produces charged particles, which it might be possible to directly harvest as electricity. The He3 fusion reaction has a high activation energy, which is currently unachievable, and there is no Helium-3 on Earth. We'd have to get it from space, somehow. (The movie "Moon" was set on a Helium-3 mining outpost on the Moon.)
I am sad to report that in South Korea, which produces fission power very well and does excellent fusion research, the leading anti-nuclear activist (also a member of congress) is vocally against fusion and already proposed to cut 100% of fusion research budget in 2018. (People thought that's too extreme so she haven't repeated it so far, but I don't think her position changed in any way.)

> How many buildings have the truckers torched?

I can anticipate the reply, but there's been an attempt of at least one, possibly with ideas about a second.[1][2]

> How many people have they injured?

This is an interesting phrasing of this. It implies an assault without injury is not an worthy of consideration.
The actual answer is not entirely known by anyone outside law enforcement I would guess but there's been a few.[3][4][5]

> How can emergency powers be invoked against peaceful protests? Ideas are not violence.

Unless your definition of "peaceful" is "the majority of participants are not looting/destroying property or assaulting people", this is not a peaceful protest.

The ideas here are not coherent either, nor are the directed at where the changes can happen. As relates to the covid mandates, the Federal government actually only has powers over a handful of areas; the majority are held by the provinces. Indeed, the original precipitating mandate could be dropped tomorrow and it would change basically nothing at the borders because the US government also has the same mandates in place.

Yes, like I said, I read the article, and I read the linked notes. The article was not really about people criticising his book without reading it, the article was about not engaging in qualitative criticism of his spreadsheets.

Caplan indirectly mentions a paper criticising him, and his dismissal is that it doesn't acknowledge the math.

It's entirely reasonable to comment on why you're choosing not to dedicate your time to something. Especially when the thing to be analysed relies on fundamentally incommensurable values.

FWIW, from actually reading his notes and the extracts of the spreadsheets he quickly dips into a number of flaky assumptions and uses them to apply "corrective biases" which make it very easy to dismiss without wasting time on arduous numerical analysis.
