> If you rely on any sort of ledger/layer 2 system, you are back to trusting a third party

It’s important to have definition of “trust” for this statement.

If we use an Etheruem optimistic rollup with on-chain data availability guarantees as an example and we assume it’s out of beta, we have three situations where I can be in trouble:

1. Censoring my transactions

2. Refusal to allow me to withdraw my funds to L1

3. The network itself shuts down and there are no longer any operators

If I am censored, I can force transaction inclusion by directly submitting the layer2 transaction to the inbox on Ethereum (the validator will get punished if they don’t include it). This will be more expensive for me since I have to interact with Ethereum, but it should only be done very rarely and my next rep should be to exit the L2 network.

If the network refuses my withdraw transaction, I can perform an emergency exit by making a call to be L1 contract and demanding an exit happens (I can also use the strategy in the censoring case).

If the network shuts down, then my only choice is to perform an emergency exit, which has probably already been started by other participants on the network.

These options do get more complicated when you start using layer 2s with off-chain data availability committees (validiums and volitions) and that’s where you do need to trust third parties to ensure you can get the correct transaction data, but it only requires that one honest party is serving that transaction data.

The trust requirements are actually pretty low for “out of beta” L2 networks while keeping the costs low enough that people can afford to use them.

ZKRollups have similar features and even lower costs but ZK-proofs are still very new and harder to reason about.
Large-scale storage clusters like Hadoop, Cassandra, ElasticSearch are generally slow, expensive, hard to set up properly and require a lot of monitoring to stay healthy. Use them only when other solutions won't do.

If your data will fit in a set of text files or a cluster of relational databases, use those. Even if you plan on storing a gazillion TB of data, it's faster to iterate app logic on nimble storage solutions first, before entertaining something bigger.

Where the large scale storage clusters shine is when the sheer scale of data won't fit in anything else, i.e. there's no other (sane) choice.
Someone has to subsidize nuclear or it never gets built. In the UK ended up being ratepayers.

In a way it's better that the costs arent disguised.
I’d hope so. Just because one bit is missing from a file, doesn’t mean the rest of the files are gone.
I thought your advice to look for contract gigs was pretty good. I'd only add that I worked in that space for a while and consultancies are generally either desperate for work or desperate for help. If they're desperate for help they will be busy enough you will have to call and call to get them to talk to you, but if they don't completely shut you down, keep trying.

Or go work for a company that makes products. You will learn a whole lot of things about bringing a product to production that you will not learn at pretty much any product development consultancy.

Note that right now in 2022 just about everyone is desperate for help. Be sure you like doing parts substitutions.

I've hired layout shops where we worked with the designer more or less directly but at "whole product" design shops, if they even have a layout designer, in my limited experience it's not usually a customer facing position.

Multiplying by 1.5 is a shift and an add, so just as cheap.

Multiplying by 1.5 has the advantage that 1 + 1.5 > 1.5 * 1.5, so the second time you realloc it fits into the old memory (which can help reduce memory fragmentation if the allocator takes advantage of it).
> it's the result of free, independent reporting, free uncensored social media communication and people coming to their own conclusions.

I want to live in the world you live in, because reality seriously disagrees with you. There's no such thing as independent reporting,
free uncensored social media communication and people coming to their own conclusions.

Not for the masses. No. Of course independent reporting etc exists, but not for the masses, regardless where you're from.

So either you deny the existence of propaganda, or you believe that "propaganda only happens everywhere else", or are unaware of the propaganda that influences you personally.

Which is it?

Satellite towns have made sense for a long time. They are the best trade-off for those who want affordable housing, urban lifestyle, and access to a decent job market. Remote work doesn't change the situation much, because most jobs still require human contact.

The recipe for a satellite town is simple. Create a fast and frequent rail connection to the central city and build dense mixed-use areas around the station, with lower-density areas farther away. The rail connection is the key. Car-centric satellite towns create too much traffic and often can't reach sufficient density to support local services.
This.
I live in Belgium coming from Italy and it's scary how many people I know gets cancer here. Like someone i know every few months gets it (and I'm not talking about just old people. A couple guys i know got it in their 20s). And it's all people relatively healthy.

Compare that to Italy where nobody I know does any effort to be healthy, eats lots of red meat (we do like our pork meat but it's all local stuff), smoke, veggies just a small side dish, no sport at all and they still live longer, healthier lives.

The few people i know who got cancer there, were well over their 60s (and all of them eventually survived).
I'm talking about the region Umbria which is pretty pristine and barely industrialized.

In my opinion the West has to rely on propaganda far more than an authoritarian government, where they can just force people into doing what they want. In the west you have to convince and brainwash them into doing what you want.
I didn't realise it was such a big thing until I visited a festival in Hokkaido a few years back and there was a very large and busy stall soliciting signatures for a petition over the Kurils and with lots of photographs and maps.

Could you provide some links? I would like to learn more about that. As far as I knew until just now the treaties between russia and china aren't all that old and the PRC has no claims on any currently russian land. But I am not well informed about the topic at all.

(After some research: The ROC and freer press were quite unhappy with the treaty and ROC still formally claims those areas if I understand it correctly.)

Overall it is an interesting (albeit very unlikely) scenario, maybe because it reminds me so much of old EU4 matches I had.
Not a native speaker and NAL, but why would anyone call this "theft"? If anything (assuming that the premise was agreed upon by both parties, of course), I'd call that defalcation, embezzlement, or simply fraud.
But as you laid out yourself, this doesn't fit any definition of theft.
You really got me there, was halfway through writing an angry reply when I read the last sentence.
EU is not a country, but it has its own economic and security interests.

The region is poor, but adding a statelet with 1 million people into a union of 450 million is a negligible burden. And local economy is already sort-of semiintegrated with the Lithuanian and the Polish one. There used to be quite a lot of cross border trade in peace times there.
That's the nub of it right there. Big Ag uses the techniques they use, because they scale. Organic is labor intensive.

Thus organic food is more expensive, so some people won't afford to eat, which is glossed over in all the hype.

It can be argued that civilization happened when the bulk of people were relieved from farming by technology. Instead of 98% of us slaving away in the mud, today 1-2% do that. I'm not sure it's a step forward, to go back to that.
No need for a "ban". Just audit stable coins and expose any fraud that keeps them pegged without the backing they claim.

This sort of fraud is illegal under current laws. No need for any new ones.

Without fraud, the crypto market would wither and die.
This is where the narrative about personal responsibility falls apart - when it comes to electricity and energy, everything is better at scale, and it's not even close. All the meaningful action is to be done on state, corporate and industrial level, individuals are a rounding error

Even with solar, where one might reasonably think the transportation costs would favor decentralized deployment - no, utility-scale deployments benefit dual axis tracking, amortization of fixed costs, integration with energy storage and economies of scale. We would all be better off as shareholders of utility solar than deploying rooftop + batteries, but that takes away the bragging rights

Didn’t think I’d be relinking to this XKCD so soon: https://xkcd.com/1053/

Maybe this is common knowledge in your circles, but otherwise it’s far from widespread. I learned about it from the linked comment (as did other people) and no one I told it to had heard of it before. That includes software developers of popular apps.
What a misplaced comment. The article is about them rewriting their own narrative.
Afghanistan was bad, but they were almost forgiven internationally, especially as one could pretend "that was the Sovjet Union". But with the invasion of the Ukraine, that is all washed away, Russia is as ugly as the old SU.

> The core problem with crypto as I see it, is that by design it cannot scale

It’s worth looking into blockchain scaling solutions like ZKSync, Optimism, and Arbitrum. They use Rollups (basically transaction batching) paired with either validity or fraud proofs to allow for high throughput at a low cost with low trust requirements.

> and by design any increase in value requires an increase in energy cost

This isn’t the case with PoS coins anymore than an increase of value at Google requires an increase in energy cost as they spin up more servers to serve more traffic. They aren’t strongly correlated.
Thorium isn't "pie in the sky", it's very doable (https://spectrum.ieee.org/china-closing-in-on-thorium-nuclea...). The issue was that thorium was abandoned by the U.S. and other countries, because uranium nuclear reactors (despite their greater dangers) have dual use, and can be used for creating nuclear weapons. Other countries followed the U.S. example, thus we must live with these greater dangers. If not from nuclear accidents or sabotage (or stray bullets), from unfriendly countries having disguised nuclear weapon production programs.

Plain and simple, we don't need more nuclear weapons or more nuclear armed countries, as we can destroy this planet several times over. Nor do we need more dangerous nuclear waste or fear of catastrophic accidents. Thorium reactors don't lend themselves to nuclear weapons production, and reduces the waste dangers. And it doesn't have to be thorium, but we can as least build them safer and smarter.

Nuclear power can be great for humankind, if we harnessed it more safely, to include using it on our moon, Mars, and beyond. On Earth, thorium is a safer and possible alternative. We need to get over our fossil fuel suicidal addiction, sooner, rather than later. Renewables are great, but its going to take us more time to get where we need to be, so nuclear power can help get us there faster.

The Chinese position on this and the implications for Taiwan are not as simple as a lot of the press seem to think.

China's claim on Taiwan is based on the principle that it is legally still Chinese territory. Crimea is still legally Ukrainian territory, so Russia's annexation is a real problem for China. They can't support it because that would undermine the basis of their claim on Taiwan. Similarly with the invasion of Ukraine, any principle China could use to support Russian's military intervention in Ukraine could also be used to justify US military intervention in Taiwan.

On the other hand big countries muscling in on little countries to take their stuff is a hobby China would love to take up if they get the chance. However their domestic promotion of Russian propaganda is more about the fact that they hate the west than it is about them actually supporting Russia at all.
Well, sure. But in one case you have a chance of winning (although vanishingly small), and in the other you don’t. So it’s much less entertaining.
So you want to just give up? Granted, I just moved away from Barcelona. But they are doing some really awesome transformation of the city while I was there. Finally you, as a person-out-of-a-car, you can just enjoy your city. They are moving away from being a tourist theme park, or the office park for the rich people from the surrounding suburbs who of course MUST be able to race into their parking spot in the city center.

The major is getting an enormous amount of shit for doing all this, and in general anything she does or does not, because car-proponents are extremely vocal about everything. IIRC she proposed a tram line on one of the car-arteries, and the neighborhood voted "no". Which is insane. Who wants more loud cars, less PT, less pedestrian zones? It should be "people who live elsewhere", and even "businesses elsewhere", because it has been proven that better access brings more customers.

So she learned her lesson and just doesn't do binding polls anymore, she just does it. And it's fantastic.

These installed western type governments rarely seem to be particularly stable. At best it would be a tentative step back to pre-2022 Russia.

Democracy just doesn't work as intended without popular support and faith in the institutions. In fact, Russia is one of the better examples of what happens when that is missing from the equation.
Imagine there is war and nobody joins the fighting.

Basically you cannot hit Putin and others without also hitting population. Unhappy population is also vital to the population getting rid of dictators. You should aim at Putin and his gang and make clear, at whom you are aiming, but cannot shy away from population being affected as well.

I corrected that. Apparently, there was just a fishing village there.

As of March 8, 2022, China has no claims on Russian land, but history shows that if a juicy opportunity turns up, countries start to come up with claims that were previously forgotten.

Yes, this scenario is unlikely. But not beyond reasonable doubt. Multinational empires have imploded and disintegrated before (Tsarist Russia, Austria-Hungary, the Ottoman Empire), and a lost war was the usual cause.
There's other things they can do rather than just more patrols. At my university town in the UK the police would plant bait bikes and watch from afar, arresting thieves after they rode off. I know they caught some, because they caught someone from one of my lectures.
That sounds extremely unlikely. Did you look into what the reflog actually is? And a tag is literally just a pointer to a commit hash. Sure, you can tag it, but don't embarrass yourself by pushing it to a remote.

That's only partially true. They could still do an autopsy to figure it out. Maybe less common.

Either way, cancer rates in you people have increased 30% since the 70s. And that's considering that smoking rates have decreased during that time.

You can freely read Chinese or russian narratives if you live in the US or EU, the opposite isn't true. Of course there are problems with the narratives created by our governments and media, especially during war time, but hey, you are free to call them out, free to provide facts that counter such narratives, and free to try and create and publish your own narratives.

The main difference between us and China/Russia is that we have access to way more information, and thus false narratives are created differently, either through information overload or information bias, but not by simply forbidding the reporting of facts.
True! Our heating is to a large part based on fossil sources, but we started to move towards more renewable sources, like wood briquettes - which would be CO2-neutral. Indeed we could switch at least 50% of our heating to climate-neutral sources right now.
All these things are highly anecdotal obviously. But the younger dog seems to try it out whenever my older dog does it.

On the one side, it is easy now to bring up those old conflicts in a moment when Russia is weak and distracted. On the other side, it could be an attempt at supporting Ukraine, as to draw out the efforts of Russia even further and give a clear signal to anyone, especially the high ranking military, that Russia might be stretched between a lot of competing crises, if they can't make peace in Ukraine.
Those are not Ukrainian sources, it's an independent channel in Russian.

If you don't believe testimonials of the people right there, the exact people who were attacked, then I see the only better source: go there yourself. What other evidence is better?

In any case, it's Russia who amassed a shit ton of military all around the Ukraine, and started the invasion.
This would require military action by Moldova/Georgia/Ukraine because the territories you mention are ethnically different and do not want to be part of those countries to start with.

Abkhazia fought a war in the early 90s to split from Georgia. South Ossetia also fought several wars to become independent. So both those territories might strive to become fully independent but will absolutely refuse to be re-absorbed by Georgia.

Moldovans are actually a minority in Transnistria, which has also seen open tensions since the fall of the USSR.

Lastly, Crimea, which was Russian until 1954, will definitely require a war and ethnic cleansing if Ukraine want to take it again and to keep it.
