This is something I struggle with personally, because over the years I've trained my brain to look for weaknesses and reasons to say "no". It drives my wife nuts, because she sees it as being pessimistic about everything. To some extent it is, because I can very easily rattle off lists of "why that won't work" or "what's wrong with that", but it's a challenge for me to come up with lists of "why that would work".

So unsuprisingly, she's CEO of a growing and successful startup, while I still nitpick design and code reviews all day!

Personally, I try to be mindful of my kneejerk "pessimism" and skepticism, and try to balance it with optimism and acknowledging that it's a lot harder for me to identify opportunities than weaknesses.

>They've have been open about their commercial paper backing.

They haven't been open at all about the ISSUER of that commercial paper though. It's one thing if it's Walmart or ExxonMobil, quite another if it's Bitfinex or some other crypto-related company.
This is clearly NOT a complicated roadmap. Any even small sized social app for photo sharing is much much bigger.
What do you mean by "moralizing"?

To me, "moralizing" is when I tell you to not do something that I don't like but which doesn't directly affect me. Like, don't drink alcohol to excess, or don't cheat at cards, or don't swear in front of kids, or always tell the truth.

I have an opinion that media diversity benefits society, and I don't consider that "moralizing". I consider it caring about my community, and I consider opposing media monopoly to be fighting back against an individual who would denigrate society for his own ends. That's not moralizing - that's standing up for ourselves.
Recent advances in obesity studies have been more concerned with chemical contamination than calorie intake or fat/carbohydrate/protein intake. After all, there are many tribal cultures subsisting mainly on only fat / only carbs, and none of the Western obesity effects are seen in those populations.

Re: Imagining AWS Re:Invent
It's important to remember commercial paper tanked and almost took the global economy with it only 13 years ago. The only reason it's regarded as low risk, if you're AIG or Bank of America, is the US government has shown an extreme willingness to bail you out by buying them at face value even when they become worthless on the open market. The US government is extremely unlikely to bail out Coinbase.
Any interval type with decidable equality is degenerate (everything ends up with a path to everything else). Having i0 and i10 be constant makes me suspect that the interval type likely has a decidable equality. This of course being on top of it missing a critical requirement to even call it an interval (transport).

I don't really understand why that section or the HIT talk is in one of the blog posts. All it seems to amount to is "yeah we can't do this." I suspect you will never be able to! There is a reason Cubical Type Theory adds the interval as a pretype with custom syntax, it is because the equality must become relevant and track exactly how paths apply. Without this relevant information I seriously doubt you will ever have any of those "possibilities."

The reason the crypto world uses dollar-pegged tokens in the first place is for their relatively stable value. The downside is that obviously this stability is not perfect, and it's managed by a centralized entity, which as monstrously big and powerful it may be, is still a single point of failure with its own interests. The real ultimate solution is to detach from the US dollar and get value stability from somewhere else, e.g. RAI[1].

Poly Network Hack: Detailed Analysis
The real problem is that no company is qualified to be the moral arbiter of all society. All such attempts are doomed to fail as the only success will be the furtherance of our dystopia.
The three biggest reasons are centralized maintenance, fuel, and fleet costs.

Taxi companies negotiate the entire fleet purchase at one time and replace vehicles on a schedule (like rental car companies). Often, the fleet is all one brand and model. This makes it easy to hire one or two guys to work on all of them. You can also buy all your standard parts in bulk and you get commercial pricing for those. Fuel is also all bought from the same vendor on a contract.

Those agreements would be impossible for any gig worker to get. He is going to pay full price for the car, the maintenance, and the fuel. Gas stations aren't owned by oil companies; they're owned by individuals. So you'll never get national pricing on gas. Each taxi company negotiates with a particular owner (hopefully of several stations) in their area.

The final nail in the coffin (and the one that keeps it from going national, even if such agreements could be worked out for a group), is that car repair is local. You cannot operate a maintenance depot in Chicago that serves Houston. The further away the depot is from the points of service, the longer the car is out of service each time.

The "hub" nature of the taxi operation with all cars, staff, repair people, and parts in one place (and all maintained on the same schedule so fewer surprises), simply doesn't scale unless you have enough customers to build another hub.

BTW, this is the same reason there's no Del Taco in Texas (or your favorite fast food where you live). You have to have a certain number of restaurants to make the distribution hub and the truck trips worthwhile. There cannot be one isolated McDonald's somewhere that's profitable, just like there cannot be a "too small" taxi operation without a hub -- it won't be profitable. And building hubs in small cities without enough demand isn't profitable, either.

Hence, taxis don't scale.

Kindly, you know little about intelligence.

Imagine if they were given up by a human source. That kind of thing doesn't leak until everyone is dead and buried, and even then it doesn't always get out because it gives foreign counterintelligence services some ability to assess the damage done by the source.

Imagine if they were given up by a technical collection program. Same thing.
So we should involve no humans at all? I think many people are clamoring for something instead of the status quo of nothing.

You absolutely can call for all people of my ethnic/racial group to be deported(or worse). What you can't do is call for your followers to go kill me or burn down my house or any other lawless action.

Sorry but no. While every community that portrays itself as “rational” would like to think that it is unbiased and skeptical toward everything, the same basic human social dynamics still apply. HN is aggressively anti-crypto to the point where I don’t even bother reading comments on related links. It’s become a Pavlovian 2 minutes hate, every. Single. Time.
The most similar feed I've found is https://feed.rekt.news/day

But there isn't a website with comment threads that are high quality. Most of the quality crypto discussions happen in Telegram and Discord.

I've realized one of the reasons programmers dislike cryptocurrency is because they value efficiency more than they understand incentive systems. They complain that crypto is inefficient and unoptimized and miss that it's an entirely new incentive system.

There's a lot to be skeptical of in the cryptocurrency space, but a community centered around outsized gains through startups should remember that pessimists get to be right and optimists get to be rich.
Very true, I believe this is why our Federal gov is aiming for 400k new immigrants per year, they know there is a large brain drain south.
It's literally the exact same arguments from 3 years ago. 3 years ago there were very few real apps/users on ethereum. At that time, ether was mostly a pet rock like bitcoin with smart contracts attached. That's simply not true anymore.

There is ether (the asset) and etheriumn (the chain), while usage of the latter accrues value to the former, the latter is what's important (and not the former). All that matters for these platforms is usage. There are other good level 1's with traction from users/developers (terra/solana specifically).

The idea that there's going to be only 1 blockchain for value transmission or that users really care about highly technical points about decentralization are laughable. People care about the apps, use-cases, and [jpegs of rocks](https://opensea.io/).

You use a jittery GPS PPS signal to discipline a highly stable primary clock through a very "slow" filter. The GPS PPS might have an RMS period jitter of say 10-20 nanoseconds, but the drift will be 0.

Then, you can use that disciplined primary clock to provide actual time for timestamping, etc.
It’s actually not very complicated how all of this works:

* Crypto exchanges have the problem of collecting fees in crypto, and wanting to make a profit in USD.

* Stablecoin operator receives commercial paper (IOUs) from businesses, usually crypto exchanges. Issues tokens in return. (Note that the Stablecoin issuers are connected directly to the biggest exchanges e.g. Bitfinex/Coinbase/Binance)

* Now the crypto exchange has a debt to the Stablecoin operator, some crypto profits, and some stablecoins.

* Crypto company trading desk does the following:

* Trade crypto (e.g. Bitcoin) for USD and take profit

* Trade stablecoins for crypto on any number of exchanges

The Stablecoin allows them to take profit without trading against themselves, and it allows them to remove USD from the system while adding debt in the form of an IOU. It also spreads liquidity risk across the entire ecosystem and allows the movement of vast sums without banking regulations getting in the way.

So yes… there is something very wrong.

What is amazing is how many people are blind to it.
> which is why now almost every single piece of software has installer that's at least 500 MB large.

I know pessimism about software is in fashion, but exaggerating the problem doesn't help. The actual size of the latest version of Electron (on Windows) is 181 MB uncompressed, 77 MB zip-compressed, and 51 MB 7z-compressed. Not great, but again, let's not make it look worse than it is.

Also, there is hope. Microsoft's WebView2 [1] means that Windows has a modern, shared, embeddable web rendering engine for the first time in several years. And Tauri [2] is making it easier for web developers to take advantage of WebView2 on Windows, and WebKit on Mac and Linux, to create lightweight native applications using web technologies.

> Financial companies are highly risk adverse.

The financial companies running COBOL are. Generally it's quite boring, staid retail banking or the like. If you're a developer who sits on a trading desk writing code which goes straight into production for a trader, things get much more risky.
"you are automatically aknowledging that the new place is a sequel and not an innovation."

Ouf I don't think this is a good statement.

We admire Silicon Valley because it produces innovation, not because it, and of itself, is an innovation.

Copying it is a good idea where it makes sense.

The Western University system was spread throughout the world in the 19th century, and then took off in the 20th century. Those Centers of Excellence (and Innovation) are basically foundational and critical institutions without which countries would not advance.

They were 'copied' and modelled after much older institutions.

If a country can 'copy' the Silicon Valley in such a manner that it yields benefits, then this is a good thing, not something to be avoided.

That said, it's to complex to copy and probably cannot be copied. Anymore than anyone can copy Shenzhen. Some principles can be grafted but need to be done so contextually.

Also, Sweden is nothing like the Silicon Valley, rather it's a country that's producing some good startups.

Most notably, Sweden doesn't have the underlying tranches of incredible knowledge in actual silicon, hardware, it's not building operating systems, it has good schools but not the best, (The Valley has Berkley and Stanford which are 'pillars' of the critical mass) Sweden not hugely over represented in terms of IP or intellectual contributions.

I think the UK / London area contributes a little more heavily in those areas.

Sweden is just a well run country that has well educated people, confident, articulate, outward looking, organized, a history of excellence, a strong sense of identity ... and so they've made some good startups.

With some ideas about Venture Capital Financing, and grafting some business models that have proven well in the US over to the EU, they've done a good job of it. But I don't actually think it's like the Valley at all.
My emotional outbursts can easily be thousands of words. There's no way to actually express emotions on Twitter. I suspect that's part of the reason for all the images and memes and links to articles.

Do the transparent clocks in your datacenter support unicast PTP?

There is a possibility to use PTP as a transport for NTP to take advantage of PTP-specific hardware timestamping. It could also process the correction field, but it seems the switches typically don't support unicast PTP.

The large asymmetry and banding of NTP in the test with Calnex Sentinel suggests it doesn't support the interleaved mode. NTP with hardware timestamping should normally be much more stable and symmetric, closer to PTP.
You might have more success looking for a HN of cryptography, rather than cryptocurrency. That is, if you want an understanding of the mathematics and solid discussions about the technology. If you look for discussions on the economics/finance, well it's no surprise you're only going to find pump-and-dump schemes and scams and shilling and BS.

> My own personal way of dealing with this would be to look at it as a challenge

This is the one point I think you have to be really careful with. Only ever do this when you have thoroughly investigated and concluded beyond any doubt that the crappy inputs you're given are beyond the control of your manager to fix.

I haven't counted but I swear most people I meet could work 50 % as much and get just as much done if they would just get their broken situation straightened out. There is so much wasted work poured into weird problems "beyond our control" but which really are fully in the control of the worker's manager.

The leading cause of this wasted work? The person doing the work "doesn't want to be seen as one who complains" or "doesn't mind the extra challenge."

But what about the time/money you're bleeding in the process?! Sorry, this is one of my pet peeves.
Hello 2013: https://news.ycombinator.com/item?id=5997368
There's a "fog of war" effect here created by cumulative effect of hype, relentless PR spin and the cultish belief in crypto as a salve for the world's problems.

If Tether and USDC have the billions in funds that they claim to, they wouldn't hire no-name accounting firms , because those firms don't have the resources or knowledge to audit such vast amounts.

An audit also puts the firm's reputation and CPA license at stake, which explains why even the no-name firms aren't committing to anything besides an attestation.
It was actually a question. I googled for a few minutes, couldn’t find anything, and threw it out there.
> One problem in these discussions is the curve of value delivered by an individual developer in a particular situation is short-and-wide

I kind of disagree with this, although I don't think it's age that separates developers. But developers who can work independently are a lot more valuable than those that require close supervision, and those developers are considerably more value than those who are actively destroying value.
Secret IRS Files Reveal How Ultrawealthy Gained by Trump “Big Beautiful Tax Cut”
I think this would have greatly helped my youngest, 6 at the time, stay more engaged during virtual learning in last year's lockdown. His teachers, who did a better job than we had any right to expect, quickly figured out some little tricks from screen-sharing 3rd party websites with fun dancing animations for "brain breaks" but nothing integrated with their regular lesson video call like this.

I hope you're able to get this adopted by individual teachers who can lead the way. School district IT isn't the most cutting edge (though, again, ours did a great job of adapting fast and standardizing on some very good resources like Zearn).

yeah, this breaks one of my fundamental web expectations--things don't scroll left to right, scrolling is up and down. If it would translate my scroll wheel to into left right action, or if it was changed to stacking old pages at the top rather than on the left, it would work much better for me.
Systems like this wouldn't replace air conditioning in all settings but they might influence the design and integration of future air conditioning systems. I can easily imagine architecture that incorporates air catchers which feed a cool breeze into electronic temperature precision units that are significantly more energy efficient. We can combine this with what we know about fluid dynamics and creating air pressure differentials to move cool air through structures at near zero cost.

AC units with massive fans doing all the heavy lifting are incredibly inefficient.
Yeah, people don't understand that the human body is remarkably adaptable. Just need to stay in a place for a while (a few weeks to months). I've cycled to school ~10 kms everyday in 35-40° as a kid, came home to cool down instantly under a ceiling fan. Now in my current city I find 27+ too hot.
