in my 25 years of software development, 90% of the time, you don't need to optimize the code and the worst solution in time complexity is totally fine. then there is another 8% of situations where trading in space for time complexity is the solution, i.e. using lookup tables. the remaining 1-2% of the cases you might need a combination of some data structures or containers from the STL or boost (in the case of C++). I've never had to roll some special version of a data structure or container or algorithm myself from scratch, and I work on some really complicated real time software.

Well, crypto is either going to be a huge success or a big flop. Whichever it is, whoever was espousing that side of the story will feel vindicated and talk about how it was obvious all along. Sadly(?) I belong to neither camp. I definitely see how clever the underlying technical/mathematical ideas are, but I also have a feeling in my gut that this is just smoke and mirrors (although, I have similar feelings for other assets like the USD and gold).

Are there others out there who are also not sure? It seems like every time I see this debate, I just see hardcore people on one side yelling at the hardcore people on the other side telling them how stupid they are (in very eloquent ways, of course).

Is it really that obvious that this is a good/bad idea?
USD is fungible. They don't have to recover your stolen dollars. They just have to get you an equal amount. And that's why it's far more useful than cryptocurrency. The government has lots of ways of giving you equal amounts, including simply creating it out of thin air.

Cryptocurrency is by definition non-fungible, and as you rightly pointed out, harder to recover.

But more importantly, if you are a US citizen you can use the services of the US government to recover your stolen cryptocurrency, but if you aren't a US citizen, you can't.

But no matter what country you are a citizen of, you can use the US government to recover your USD.

Abuse happens to people who don't have other options. If you abuse someone who has a white collar job, they generally leave quickly.

If you abuse a poor grad student who has to complete research to pay back his loans which cannot be discharged through bankruptcy, he will generally put up with it.
"Legacy" here means that it (substantially) pre-dates the IETF deciding it needs the arrangement described in RFC 4844

Today a document like RFC 768 would most likely be the product of an IETF Working Group (possibly after being initially drafted outside and then adopted). In some cases an Area Director might authorise somebody to write a document without the Working Group process under their direct sponsorship instead. Together these form the IETF stream. This stream is the only means by which the IETF produces "standards track" documents, although it can also produce other documents from this stream.

Two other related groups, the IAB and IRTF, might create documents the RFC Editor cares about, they have their own streams. For example RFC 4844 is from the IAB stream.

Finally there are Individual Submissions. Sometimes these are documents nobody in any Working Group or Area cares about, occasionally they are documents a Working Group abandoned because it was unable to reach consensus and those who favoured the document finished it up as an Individual Submission. In some cases they're documenting a thing the authors would like to be public, just to get it down on paper.

The "Legacy" indication just means RFC 768 is too old to be classified by stream, the whole idea didn't exist back then.

The solution is an internal marketplace. Large enterprises formed from conglomeration often flub this. They often end up with a half dozen or more datacenters and ops groups. What do they do?

Consolidate them, and a knife fight happens between middle management machiavellis and the one that wins is not necessarily the best on price or features. It's the one who is best at winning reporting hierarchy wars.

Instead they should pit these groups against each other as internal options for hosting to various services that provide what is needed for growth, adaptation, or cost.

AWS should simply be one of those options. Really it can be the prototyping phase, and then budget squeezing will move the app to other (hopefully cheaper) inhouse options.

What is frustrating from my years in the big corps is that AWS was cheaper than the internal "clouds" or other relationships.
For sure it does. But it’s also common for technologies to mature as they gain widespread use.

I think Windows could succeed with UWP if they embraced 0% sales commission, and just charged a yearly fee per app (which could scale based on units sold, to cover credit card fees).

They should allow developers to directly distribute the software from their own websites, and for 3rd-party stores to sell and distribute UWP apps.
"The leaders are in power to do what's most beneficial for their population (domestic hyper-development) "

Their goal is 'Neo Han Imperial China', a 'Global Power' / 'Centre of the Earth' and to make most states in their direct influence (including Japan) vassals or lesser powers, which they view as their 'normal' place in history.

They'll literally grab massive swaths of what the rest of the world regards as either international waters or domestic territory of other nations, and declare them as sovereign - right as everyone watches. Nobody will do anything about it as the maps are redrawn along with history.

At the same time, they'll declare 'something something aboriginals in USA' while they put 100's of thousands people in jail on the basis of their ethnicity (Uighurs), move millions of Han into Tibet to secure control, and use every means to force Taiwan to fall just like Hong Kong.

And that's without any discussion of internal controls.

Authoritarianism aside, there is some degree of legitimacy in their own governance, after all, it's their own, however - the spillover effects are real and their ambitions lie far outside their borders.

you can set up a trigger port, that will open an SSH port when triggered properly. some routers come with this functionality, a third party opensource firmware usually does this or allows for a script to implement it.

so you "knock" on port 666 lets say with a majic packet of some sort this opens a secured SSH port, then drops it on command or idle time to live expires
The outer hard enamel layer of your teeth is acellular and cannot regenerate after it forms. Its been a while since I worked in this field (my PhD) but the inner dentin has some ability to regenerate due to the adjacent cells in the pulp. I'm not really sure I understand what the previous comment is saying about the crystal structure. All of the tooth (enamel and dentin) and bone mineral related carbonate "hydroxyl" apatite is crystalline with some additional amorphous material in between.

I'm not aware of any other story-- about US hardware or otherwise-- that has shown a drone operating solely upon its own programming to attack a person.

I meant natural in the sense of originating from nature, specifically as opposed to something built by people. The fact that digital computation is a synthetic construction of humans is what makes it “unnatural”, that it’s new is just a byproduct humans having invented it recently.

I’d agree there are ways that we can observe computation as a scientist and form hypotheses and perform experiments, especially if, for example, I write a program I don’t fully understand and don’t know how to predict the behavior of, or more maybe much more commonly when I observe software written by other people.

Thinking about the analogy to telescopes, the implication is that computers are an instrument for measuring something. Telescopes measure things about planets and stars, physical things that occur in nature. But what exactly do computers measure if they’re to be considered a measuring device? It’s fun to think of a computer being a physical device that measures pure logic; we can physically observe something that doesn’t occur in nature.

On the other hand, I’m hesitant to not draw some kind of line between CS and the hard sciences like physics, chemistry, biology, because there seem to be real differences between them. (I was going to point out examples, but realized it’s fundamentally tricky to nail down and I’d be setting a trap for myself. ;)) Yes I agree the philosophy of where CS lands, and what CS really is, does land in the same ambiguous camp as mathematics (probably because CS and math both truly are in the same category of abstract logic, not directly tied to physical observations.) Maybe more useful and abstract tools are more difficult to categorize precisely because they are used as part of all the sciences and arts...

Not sure about some of the other things, but if you're looking for binoculars outside of work, it's probably for hunting, birding, or sailing. Having done those things, generally a decent 8x42 is all you need. And remember, you're taking them into the field, so some exotic Swarovski 10x50 or Steiner 8x32 laser range finder with compass at $9k is going to make you really sad when it fails. But a 8x42 Nikon Monarch is fine. Absolutely fine. And you won't hate yourself when you drop them out of a blind, or in the water, or swing them into a ladder as you shuffle down in the dark.

That said, smaller binos are fine in most circumstances. I often carry pocket 8x23s around, or even a small monocular, just in case.
Possibly, but my experience is that front-end dev specialists tend to over-complicate things (usually so they can tinker with some new javascript flavored garbage).
> Give poor people money they will spend it and the market will figure out what they want and need faster then any rich person.

If the market will figure that out so fast, then the way for poor people to become not poor is to become part of the market. Produce things that other people want, and sell them.

Giving people money as a one-time gift to help them bootstrap their way to doing that is a great idea. Rich people do that all the time; they're called "angel investors". The government can't do that; certainly that's not what UBI is.

The key point you are missing is that if you just give people money, and they spend it, and don't produce anything, you haven't helped the situation at all. You've made it worse. It's not enough for the market to figure out what people want; someone has to produce those things. Money flowing back and forth between people depends on everyone producing something. If money starts flowing to people who aren't producing anything, the incentive to produce goes away, and the market will stop being able to provide the things people want, because nobody has any incentive to produce them.

In fact, the arguments being made in this discussion about rich people being inefficient at spending money are based on precisely this observation: the rich people aren't producing anything to match up with all the money they have. And the argument for redistributing that money to others who will make better use of it is that those others will produce more with it than the rich people do. The fact that the others will also consume more is just looking at it from the other side. Nothing can be consumed until it is produced. So you can't just give people money for them to consume it; that's just as bad as the rich people having it. You have to figure out how to use that money to produce more. And that's something governments simply suck at doing.
The good solution is to simply tax landlords to get decent ventilation installed.
Teeth have remarkable intricate structure, simple depositing some disordered mineral using a bio-mimetic peptide isn't the same as regenerating your enamel. Remaking your actual tooth material is very difficult (currently no method is really known). Once the enamel is formed the cells die off and you are stuck with what you've got. Hopefully restorative options like this may be modestly successful but I'm skeptical. I worked in this area during my PhD.
> due to how tedious the game can sometimes be people ignore it because it’s too [much] work.

The view that the game is tedious is directly caused by not reading the rules.

Monopoly is in an odd position where everyone is convinced they know what it's like, and yet nobody knows how to play it. Turns out, if you play it according to the rules, it is not at all similar to the version with rules you made up.
I clearly see a path forward where competition will work.

I truly see an horrible path if government starts to put its big fingers everywhere and start causing all kinds of secondary market effects. When you look in hitory, it ALWAYS ends up being worse.

Nobody speaks about Walmart only sellers, that don't want to work with Amazon (as they are crazy with sellers).

Nobody speaks about Ebay sellers, nobody speaks about shopify only sellers. Nobody speaks about LOCAL sellers.

Those are all competitors than Amazon has no control over it.

Yes Amazon has a large distribution network, and competitor are starting to catch up from what I can see.

But anyway, what can I do other than expressing my disagreement ? I very well know we are going towards a gov intervention. I can only laugh in my corner, alone...
There isn't really only a single viable or perfect system. Each monetary system has different tradeoffs. Commodities work well until liquidity becomes a problem and so governments print fiat commodity-backed currency. Eventually a situation arises and the government needs extra $$$ so they start to inflate the currency and eventually remove the backing once everyone is already using the fiat currency. Credit systems are great for liquidity but have cascading failures once a situation arises requires settling up.

You don't need the first roll either.

At the very beginning of the game, offer your opponent $1,600 in return for a 50% stake in all the rents they collect for the rest of the game.

Your opponent accepts, and you can't pay. Game over.
At least landmines don't actively seek out targets. They're a disaster, absolutely, but this seems to go a step beyond that.

That said, I have found marked differences even in "consumer" duct/duck tape offerings at big box stores. Adhesive properties, abrasion resistance, UV resistance, backing laminate strength, vibration tolerance, and so on, have converged my choices these days to Gorilla and 3M brands, and only give other manufacturers that show up in the big box store shelves one chance with one sample roll.

If you care about this issue can you consider editing your first paragraph? It's likely to preemptively derail the discussion you're trying to get started.
You most likely weren't following all the rules. Monopoly shouldn't take more than about 45 minutes of game play if you follow all the rules.
So I have two options. I can either hide the fact that I find that video incredibly cool, or just be open and honest about it.

If you’re wondering why it’s an effective video, it’s because it makes me want one. I don’t even have anything to blow up. That’s the essence of effective marketing.

We can also recognize that in the wrong hands, it’s an evil device. But so is a gun. And I would imagine the reactions to the first portable guns may have been similar.

Lots of people find guns cool, and I have lots of fond memories of shooting with my dad and a friend. Learned about gun safety and how to properly care for one. I also learned I wasn’t responsible enough to keep one, so I’ve never bought one.

This is obviously different. But it’s not inconceivable that in the future, you might be able to deploy a sentry quadcopter designed to chase down (not destroy) someone who just attacked you. I was shocked that there was a drive-by shooting in my neighborhood a few months ago. Would’ve totally sic’d a drone on them the moment I heard the gunshots.

Dunno. Sometimes I feel lonely for feeling this way, when the only acceptable social response is outrage or indignation. It’s cool to blow things up, and humans have had a long and proud tradition of making things go boom.

The key is to make sure that this tech won’t have unforeseen consequences. But as far as I can tell, the consequences appear to be foreseen in this case. It’s a drone that goes boom when next to someone.

All that said, I agree that it’s a terrible idea to let it decide to do this automatically. But in a warzone, it’s not impossible to imagine some heuristics that might make sense in certain highly constrained circumstances.

Of course, most dictators don’t really care about minimizing civilian casualties, and dictatorships seem like the target audience. But, ditto for guns.
I read the rules of the Swedish version again.

It's very specific in that if it isn't bought, it HAS to be auctioned and it HAS to be sold and that any amount can be bid.
I certainly don't think you should be ridiculed for the notion, although I think my counter thought would be why should it be one or the other, and how confident are we in the engineering side of the solution at a wide scale.

To my knowledge masks are a low cost / lost risk way to reduce the spread, and countries that had faster uptake and higher rates of compliance in mask usage did see lower overall case counts.

The building ventilation side to me seems more like a long term solution, with lots of details to implement. How can we be confident that someone did the retrofit correctly, and tested the air pathways to make sure there isn't droplets being pushed from one table to another in a restaurant. Can we be confident that small changes to dampers, rearrangement of the dining room, other changes don't affect the conditions and are maintained over time. Building HVAC systems are hard enough to maintain as is.

This seems like a great addition to building codes, or if some standard can be developed for inspection, maintenance, testing, etc. And how can we be sure that businesses don't just try and cheat, would they be liable, can this be inspected, would the liability be collectable, etc, etc.

I think as a society we should be looking at this problem holistically, I think part of the solution is masks, and part is vaccines, and part should probably be building codes and HVAC systems in public indoor spaces to reduce a variety of airborne pathogens.
"Autocracies "do as they please", which can take them to great height"

History informs that by and large, autocracies are exceedingly slow and inneficient, and tend to perform well only in periods of post-trauma with acute nationalism and oversight/economic aid from friendly partners. And when there was some kind of civilization there previously.

The reconstruction of Japan and Korea after WW2/Korean War were exemplary of this but they had a lot of key favourable conditions.

One could argue that China's recent development is frankly just a delayed post-WW2 kind of rejuvenation but they'll get diminishing marginal returns on authoritarianism as leaping ahead of other systems is much harder than doing the obvious of building new bridges and roads.

And over the last 6 years China has increased centralized control even further.
Man, that was rude. Feel better now?

Fortunately they didn’t have an attention monopoly either, in part because they didn’t have an information monopoly. :)
What things were discovered accidentally?
This is exactly right. Cryptocurrencies are digital gold. That's what makes crypto so scary. When gold was made too central a part of the monetary/financial system in the 1920s and 1930s, it caused the Great Depression and quite possibly WWII.

Deflationary tokens, if they get too enmeshed with the financial system, tend to be hoarded to a point where they displace productive investment on an economy wide scale, putting a huge gridlock in the economy.
