Vacuum Energy

Energy extracted directly from the vacuum. Nothing to burn, nothing to consume, nothing to destroy. No fumes, no toxins, no limitations. Nothing short of a paradigm shift which will alter the course of human kind forever.

If he wants to do it for nature’s sake I bravely assumed he wouldn’t plant a monoculture of unfitting trees but something that is common for the climate and the area.

Trees are good for the soil (help against erosion), the microclimate (shadow, humidity, temperature) and help in times of climate change. I assume a mixture of trees and not too narrow planting (as is sadly common in many parts of the world).

Many farm lands had trees in them before these lands were cultivated
I've evaluated both (and also lumen) briefly. I disliked the half-way approach that doesn't isolate Lua's messy state handling from lisp model.

Clojure also interacts with Java, but it feels like CLojure is the host that runs Java methods as needed. The separation is clean and you know exactly when you are crossing the boundary into stateful territory.

I see the value of those languages for lispers wanting to script the platforms where Lua can run, but not really as a core language for modelling your domain.

> it also happens in the EU that one item will be shown as €/100g and another as €/kg

In my experience this difference is decided by what a "normal" amount of the good tends to be. For example, €/kg is usually used for meat, flour etc, but for something like spices or herbs a price of €/kg would seem silly since you rarely buy, and it's rarely sold in, a kilo. Still, a luxury of the metric system is that even if it's listed as €/100g, all you have to do is multiply by ten (aka move the decimal one step).

Amazon certainly isn’t a monopoly. You’ll want to provide more evidence to back up these claims.

More of a meta point - there’s generally an anti-FAANG article about everyday on HN, and the underlying editorials are typically these same batch of outlets who directly compete with Facebook, Google, or Amazon directly in ads or video content.

I take the latest pieces on Bezos forcing warehouse workers into slavery with a pinch of salt. You can certainly believe whatever you want, but these absolute claims with no evidence are hard to take seriously.
The only 'saved money actually doing nothing' scenario I can think if is when it gets deposited in a bank who then turns around and hold those funds at the central bank because they have nothing else to do with it. Central banks in many currencies these days offer negative deposit rates to discourage that behaviour and thus to the extent it happens it tends to only be over a very short period of time.

Of course it doesn't mean that investors/banks who receive the money reinvest it in the same country - if there is a dearth of opportunities in eg the US and Europe then this type of activity may result in increased investment in emerging markets.

That's super interesting. I had the same idea. I was thinking if there is a case in the current financial environment to just collect money from VCs, corporations etc and then buy land and make it "human-free". If you look at Chernobyl the results are very promising despite the radiation...

Specifically, Signal's secured VoIP is Ogg Opus (better performance than the technology your phone uses to make actual phone calls) but in CBR mode (compression but with a fixed ratio so that a frame of audio is always the same number of bytes, thus a MITM attacker can't determine anything except how long your call lasted)

An unencrypted voice chat app could do VBR Opus, which would need slightly less bandwidth on average for the same quality but might mess with flow performance estimators in the network and make the experience worse by mistake.

One of the inadvertent benefits of Signal's strong centralisation of control is that they could just go "Opus CBR is great, we're using that now" and do it. No multi-year phase-in with most calls still being "legacy", no need to accumulate "buy in" from third parties who might not prioritize this work, they just did it.
Backpropagation feels like a pretty gross hack to me anyway. It is a powerful component that still needs a large amount of additional hand-engineering to do more than recognize shapes it has seen before. And it's quite mathematical, which seems kind of difficult to implement in a brain.

Edit: The article and code try to show how backpropagation might work given neuron behavior. I'll leave discussing the quality of the model to biologists.
I'm always reminded of my college friend who went to an international private school in Asia.

Her classmates were the children of billionaires and sultans. Everyone in the school would know because you could just Google them and find paparazzi pictures of them with the parents.

She said for the most part, they did act like normal teens. Just more aloof because the second they left the school, they had a contingent of people, like bodyguards and chauffeurs. Perhaps people like that change more when they are in college.

Theoretically, in addition to the warp drive, you also need some kind of secondary propulsion, no matter how slow, to move the ship through the warp bubble/vortex/portal/curved space, etc.

Later versions of warp will be able to move the bubble/vortex/portal of curved space itself -- around the ship and from front to back, thus obviating the need for motion relative to the warp field.

Technology-wise think of the steps like this:

1) Figure out how to create a warp bubble

2) Figure out how to move it, relative to what's projecting it

Without #2, secondary propulsion is required.
#1 is the first technological achievement, #2 would follow upon that. Until #2 is achieved, secondary propulsion is required...

#2 is a little bit wierd to do, because once you've changed your location in space, you've changed the location of what's projecting the warp field -- you need to include that in your warp field projection calculations for #2... and that's IF it could be done...

In fact, the initial version of warp might look something like this: Ship A, stationary in space, projects the warp bubble, Ship B goes through it. Why? Because otherwise you've got all kinds of relative motion that would need to be compensated for...

Of course, all of this is theoretical...
I'd argue they don't need it, out of the 10-20 people I know that use Telegram I've never heard one of them mention it being something that bothers them, especially not since you can send video clips (which arguably is better anyway in my opinion, since it sacrifices near-real time comms for no stuttering, and I vastly prefer the latter). I imagine the ones that really do care about real time video chat will solve it through a different app for the occasions they use it. Hopefully Telegram is aware that they shouldn't sprawl too much, lest they risk being seen as a worse alternative to Snapchat, Duo, Skype etc. in addition to all the lunches they're already eating.
What exactly is a "partition-free network"? In my understanding no such thing exists, a partition can happen even if all the servers run on the same physical hardware (because of networking stacks, bugs, misconfiguration and so on), and even if they think that no such thing can happen if runs for eternity it will eventually happen. The question that CAP asks is what happens when a partition happens? Does the DB

I think this is a very common perception issue. I am at a university with enormous wealth concentration, but wealth is opaque and everyone orientates upwards.

For students without means or parents buying them toys, someone buying an iPhone on a whim because their old broke is rich. Having any money to spend on non-essentials is rich.

Students who can buy an iPhone on a whim because it's just a random expense for their parents would never think of themselves as wealthy - that's the people who go on first class trips and wear designer clothes without thinking twice.

The people who wear overpriced clothes and go on expensive trips don't feel rich either, they don't even have a building at the university in their family name, and no multi-generational wealth.

I briefly went out with the daughter of an Asian billionaire tycoon, the kind with lots of buildings named after. She never mentioned it or brought it up and I wouldn't even have known until it suddenly clicked about her name and the name of some buildings. I never asked her who she orientated upwards to, though. Some richer tycoon's family?

1. Farming relies on pollinating insects. Insect die-off is a great way to make it more expensive.

Cow breeding is an almost entirely human-controlled process, we could phase them out in a few years while eating them unwastefully. But the problem is not the cows, it's the owners whose livelihoods you've stolen.

I have somewhat sympathy for Black Hat, especially with the "pay for talks" model that they seem to get funding from, it's easy for these things to get a platform.

I went to a maker space in the UK that occasionally held talks - one day they had a talk by some "Alkaline water" machine manufacturer (not the manufacturer, but one of the pyramid scheme dupes). Like many of these, it was a random mix of diverse actual (irrelevant) science, pseudoscience bullshit, conspiracy theory (as to why this wasn't e.g. used in medicine), appeal to authority and outright fraud, gish-galloped together into one giant mess. The diversity of the actual science means that there is _nobody_ who can be an expert in all areas and so refuting can be waved away.

Many of the otherwise practically intelligent people (although a wide mix came to this space) apparently couldn't tell or didn't care. Several people actually bought machines from them.

I suppose all of this is (in these contexts) is preying on the tendency for competent scientists to automatically question their own assumptions, but even when they do most of the time it just feeds their "controversy" argument using people who would never have bought it anyway.

Con-artists continue to thrive for a reason; even with the canniest/most suspicious people there's an arbitrage on how long they can survive in one place before moving onto the next target.

Buybacks and special dividends are economically equivalent. Buybacks allows individual investors to either sell or hold.

The majority of investors would usually prefer to hold at a given point in time (or at least would prefer a choice of when to realise their gain), so unless the sum is so big that a buyback is not practical, it is usually preferable from an investor perspective as it lowers average friction costs.

In some jurisdictions buybacks may also be more tax efficient for some investors than special dividends (and this may be especially true for senior executives who make the decision on which to do), but that's not the case everywhere or for all investors (some may have a tax preference for dividends).

Seeing that WhatsApp is not prohibited in Russia is a big concern of itself. This country has a law that requires you to pass ‘master key’ (or a backdoor, if you read between the lines) to special agency, or be banned by all ISPs. When my friend researched the topic, some interesting guys told him few years ago that whatsapp is a no-brainer for them to read, but tg+secret is opaque. Subsequent events shown that it was probably true.

All this is full of false negatives and positives, but concerns too much to ignore, if you’re after secrecy that puts your welfare at stake. If you just hide your pics from a corporate big brother, I admit that whatsapp and regular tg chats may have different weights on scales.

You're talking about "secret chats", the Telegram way of doing E2E, but it doesn't mean that all other communications are sent or stored plain text. And there is no setting in the app to enable encryption (I just checked), because there is no way to disable it. "Not E2E" != "not encrypted"

TIL DoorDash actually delivers to where I live from quite a few restaurants--though the vast majority I wouldn't consider. I think they're the only delivery service that covers my address.

To your point, if I were to use them, quite a few of the restaurants are a good 15 minute drive from where I live. Which is further than I'd bother to go to get takeout. It's also further than I'd probably chance to get, say, a burger delivered as I suspect it would be getting cold by the time I got it.

But no language, no matter however opinionated, does get most things right, does it? People complain about C, C++, Java, Go, you name it.

I know many people are averse to the idea of macros that makes Lisp so malleable (you can add syntactic abstractions like in-fix expressions etc.) but the same people are not averse to adding new types with classes or new "operators" with functions. I find it curious that many are comfortable at stopping the level of abstraction at just that (types and operations). For some reason, the idea of abstracting away syntax itself or dynamic function definitions (macros) is unpalatable. Why should the comfort for abstraction stop just there? Just like one can make a mess with types and functions, one can make a mess with macros. Just like one can write beautiful and elegant types and functions, one can write beautiful and elegant macros. Does the aversion to macros come due to the traumatic experience people relate to when they think of C/C++ macros?
But banks are taxed on their net interest margin at the corporate tax rate. Its the same argument as for the 'dividend tax credit' system which Australia has and the UK had 20+ years ago (which used to be called 'Advance Corporation Tax'), ie tax capital returns only once and in the hands of the investor not the payer where possible.

"... you can only patent processes ..." -- This is not true, as far as I know. Patents are about invention / innovation (not necessarily in a process-focused format). For example, see https://www.uspto.gov/patents-getting-started/general-inform.... Many, if not the most, patents are essentially about idea or a coherent set of ideas, which sometimes is/are "wrapped" into a process-focused legalese of a varied "thickness".

Thanks for the summary.

> First check the remainder modulo 10, modulo 9 and modulo 24.

This makes zero sense already. First, 9=3 x 3, so checking for 3 is sufficient. (Checking for 9 might be easier in decimal, but why the hell would you do cryptography in decimal?) Then there’s the 24=2 x 2 x 2 x 3. Again, why not just use 6, but even worse, there’s no new factor here that’s not already covered by 10 and 9.

Well, that's a problem with many aspects involving "wilderness", not just insects. The usual train of thought seems to be that yes, natural landscapes are occasionally pretty, but as a farmer it would be irrational to have them on your land.
Problem of course, if there is someone for every patch of land who says "not here", then in the end, there is no room for it to go at all.
