> The point is the economy is currently based on something hits the news, hoard hoard hoard, price explodes, empty shelves and high profits.

Given that that extends well beyond individual behaviour (Wheat futures[1] are currently bonkers), this raises the question if the claim that "capitalism is the optimal way to allocate resources" is really true at least for the current version of capitalism.

This extends well beyond wheat. Market behavior is often completely irrational, for extended periods of time. The idea that "all information is priced in" extends to entirely made up information of any kind, which, given technology's ability to proliferate information, now means it often outnumbers actual information significantly.

This means that the markets often don't reflect a fair price for the product any more. They instead show a price that is an excellent representation for human emotions around the product.

That does not seem a sustainable principle, in the long run.

I wish I could close with a lovely "and here's how we fix that" paragraph, but it's a problem that leaves me stumped.

Not losing transactions with a database is not exactly terra incognita.

Depends what you mean by "distributed". A simple 2-phase commit would do it. Or hell, just a write-ahead log on the application layer.

> Postgres just doesn't seem like the best way to get distributed failover safely

That may be so. But are you arguing in favour of blockchain? When was the last time a real bank forgot your bank balance? They never used blockchains for this.
> You work in a SW team, and a peer who has many more years of experience than you is the lead for a particular project. He doesn't want you making branches for different experiments, as "branches complicates things". Instead, there will be only one development branch and you have to make command line arguments with switches in the code for all the various experiments you need to do.

It would not be my first choice, but committing on master and having feature flags can potentially be a good fit if you run tons of experiments. A company I used to work at did this and it ran very well.

I was at a place for many years where the CEO was quite bad. He had few skills, both technical and interpersonal. So many people in the organization had strategies for dealing with him, distracting him away from important work. I was always disgusted by the wasted efforts of the entire organization finding ways to route around this CEO, and leaving was one of the best things I ever did.

> I highly doubt that messages are actually being deleted from the system - that's rather an expensive affair and not fashionable from state security point of view.

State security concerns aside, deleting messages is less expensive than keeping them. If your plan is to delete everything after N days, it's easy to partition data by day, and then drop the older partitons as needed.
> I think even crypto-skeptics can see the utility of crypto in situations where people do not have access to functioning banking system.

In this case, the Ukrainian government does have access to the banking system. It sounds like this guy is just managing once channel of cryptocurrency donations, which I'm sure isn't their largest channel of financial support. The headline here is pretty misleading, because it makes it seem like cryptocurrency is doing something special.

And the problem with your general sentiment is that cryptocurrency requires access to quite advanced technical infrastructure (on a personal and civil level), which in many situations is contraindicated by "not having access to functioning banking system."

The main use of cryptocurrency is in this crisis is probably for Russian oligarchs to avoid sanctions.
You’d first move to dismiss for failure to state a claim, and perhaps counter-sue under anti-SLAPP.
Just because indexing is bounds-checked by default doesn't mean that the bounds-checking is necessarily in your final code:

I don't think it was just "muh War on Drugs"

Signal processing may be unusual, but it's generally not true that professors know which papers are likely to replicate or not:

https://fantasticanachronism.com/2020/09/11/whats-wrong-with...

"studies that replicate are cited at the same rate as studies that do not"

Confidence is eroded in all papers by this sort of thing, because academic structures are the same across fields. Whilst individual fields or labs may be more rigorous than others, people can't be expected to keep a massive database in their heads of which fields are good and bad. To be able to generalize about quality requires institutions that create quality, but universities don't do this. And because universities dominate "science" or at least the public discussion of it, that lack of quality control reflects on all science.

I'm not under the impression that e.g. pressure vessel design or bridge building follows the same safety rules now as it did 40 or 80 years ago. You might learn the same basics in university, but in practice the rules and tools are also evolving all the time.

So the "robust, time-tested tools to solve problems" also become obsolete in other fields of engineering. I think this is not unlike "compiler warns about more unsafe practices nowadays".

She talks about this further down in the thread, making it her main point:

> Again, specific places are facing EXTREMELY REAL wheat supply problems. MENA usually sources from Ukraine. Switching supply chains to India & other sources takes extra time, & if they're further away from India and Ukraine, it takes longer for supplies to get there.

and

> To solve that problem, we gotta start with being clear on what the problem IS!

> We haven't! We decided it's a wheat shortage, not a shipping shortage.

> So investors panicked, drove up the price of wheat, & made it even harder for these places to get new import shipments launched
I'm also a lawyer. The things that caught my attention were the embarrassing misspelling of the word "damning" as "damming," and the fact that this was drafted and filed by a specialty boutique law firm (Clare Locke LLP) - I'd have expected a company with Ubiquiti's resources to bring out the big guns with a white-shoe Washington-area firm. Makes me wonder if the company is on the skids.

I don't understand why she mentions "most of the world plants wheat in the fall" if, as far as I understand, Ukraine plants their wheat in the spring. Since 1) we're in the middle of their planting season 2) Ukraine produced 40 million tons of wheat last year 3) Given the current situation it's very hard to predict how much wheat will be successfully produced this year - It looks like the majority of farmers won't be able to grow their crops - how is she so sure about the 7 million ton shortfall figure? It seems reasonable it will be closer to 20-30 million ton shortfall for this year/next year unless I'm missing something.
Trust is the biggest issue with cryptocurrency. I can trust my bank + the government to keep my money safe. As has been repeatedly demonstrated, I can’t trust an exchange and keeping your own wallet is extremely risky.
And so it goes for all cryptocurrency selling points.

But just to be clear, in case others have not heard: It's definitely being sold as financial inclusion.
> I think even crypto-skeptics can see the utility of crypto

No. Electronic payments based in a stable country, yes, but that doesn't have to be crypto blockchain speculative shit that passes as a fiat alternative today.

And the stablecoins so far aren't. If anything, they're the ripest area for corruption in the crypto network today.
A 20 year mission to Pluto would be unsuccessful without cryogenic or otherwise science-magical-sleep system. I cannot imagine a single set of humans who could spend 20 years together, without any way to leave the small space of a ship, and not absolutely lose their minds.

A system should only be a mystery in so far that you were too lazy to look up how exactly something works. Having "undocumented service" running wild should be unacceptable, even so it has become so common place. Linux isn't free of this, far too many times there is no man-page to tell you what something does, but at least you can dig into the source if you have to.
If the shortages are in rail lines, grain elevators, shipping terminals, bulk cargo ships, etc...no sort of "support" can create those at all quickly.
If they really wanted that, they would craft a less emotionally loaded complaint and try for discovery ASAP. I think.
And the Axie Infinity token price rallied about 10% after this news, strange.
That's certainly interesting, but it just doesn't fit with the yearly consumption data available. Even if you take a look at [1], which distributes all electric energy consumption onto citizen you barely get 6000kWh/year. Which brings us (barely) to 2kW per household (btw. I find it kind of surprising, that there is a factor of 3-4 between total and private consumption).

So either they are taking all electric energy consumption and not the consumption of the household as their basis or (and more likely) they are talking about installed peak capacity necessary to provide the required electric energy over the year. But we would have to look where their marketing got their data from.

I work in signal processing and as a field of theory it presents no barriers to replication. My fiance is exiting chemistry academia due to an abusive professor. In the past they have wasted over a year of effort on one project trying to build off of prior work. The conclusion they ended up with is that the original work was fraudulent. No paper covers the inability to replicate the previous work.

So what does this mean? The professors pushing the papers out are not doing their due diligence and there is no one else doing public checking. The loop is open. It is not science. That's the crisis.
A PDF can be reflowed without reconstructive processing only if a PDF was generated as a Tagged PDF [1] and if the viewer supports reflowing.

[1]: Essentially a PDF with its own EPUB inside it, but unlike just having an attached EPUB, there is a map between the page layout of the PDF and the tags.

There are implementations of reconstructive reflowing that infer the layout block structure and reading order and can reflow a two column paper into a single column.

In both cases you're well protected against the solar wind by distance and atmosphere in the case of the Mars rover and by the Van Allen belts in the case of the Space Shuttle. But both still have to worry about cosmic rays. Mars's thin atmosphere helps a bit with that but not nearly as much as you'd like.

EDIT: I suspect a lot of what lets you use Snapdragons in the rover is the idea of making error resistant systems rather than error resistent devices. The same thing that let us replace a single $10,000 hard driver with ten $100 hard drives in a RAID with the same performance and reliability despite the individual drives being much worse.
I have been thinking about this and what I really hope we do is build a fully automated colony in space. Making it livable for humans is a huge pain in the ass, but if we restrict the scope to just sustaining robots then it becomes easier.

Energy is easy: Solar panels. There is also repairs which might be trickier. Need to mine for materials and refine them into spare parts.

Once you have a self-sustaining colony you could use it to assemble useful stuff. Luxury goods for terrestrial consumption. Or you could use it to build a stage-2 colony that is suitable for humans. Or maybe rockets and stuff to keep expanding into space.
Learning how to code is not the same thing as learning how to write commercial software at production level. There are lots of ancillary skills that must be mastered (git, testing frameworks, cloud deployment), lots of concepts that must be learned (dependency injection, the rule of 3, CPS, etc), and soft skills that must be mastered (how to accept criticism of your code, how to review other people's code, how to have a technical argument without getting emotional, how to tell your boss they're wrong).

Like most professions, there's a lot of "extra" stuff around the core competency. Knowing Excel does not make you an accountant.

My guess is dictation.

My Trial folder is about 500MB. I've never enabled Siri on my computers declining the option during the setup at first boot. But I do use dictation quite a bit.

If 500MB is the cost of having dictation work solely on my laptop without hitting the internet, I'm OK with it.

The problem is that people love to invent conspiracy theories about Apple because they have an axe to grind.

They get opportunities to do so because of two things: Many of Apple's daemons and other services are not publicly documented. And because it's running a flavor of Unix, it is a lot easier for amateur computer sleuths to poke about and discover what's running that people outside of Apple don't know about.

Operating systems of the past were more opaque, so we just had to blindly trust the manufacturer. But people can see things better now. It would help rebuild trust if Apple would have a standard reference online explaining all of its OS bits.
I live in Argentina and crypto is the best solution available today. I've tried multiple services like Paypal, Payoneer, Wise, Bankera, Paysera, Wester Union, etc. They all have the same issues.
Scientists in the natural sciences/mathematics criticizing the social sciences (and also the humanities) is literally a trope.

That's a cool puzzle! It's the same as the Bridges of Königsberg, right? If each square is a node, connected by edges to adjacent squares, then it's only solvable if there are at most two squares with an odd number of edges. Think about it like this: except for the squares where you start and finish, you must use one edge to enter and another to leave.

I guess the Zelda puzzle is different because in Königsberg you can revisit islands, just not recross bridges. But that feels like something you can finesse somehow. . . . Ah, just swap nodes & edges, right? Squares : bridges :: sides : islands. Indeed, that lines up not just the restriction but the goal too.

EDIT: Oh your second link is a much nicer solution. But still it feels like there is a relationship to Königsberg.

Knowing how to invert a binary tree is proxy for knowing how to do other none-trivial tasks in your domain of choice. It's so much better than the alternatives for interviews. Which are questions like, obscure trivia, spot-the-bug, how-many-piano-tuners-are-in-chicago, or two-day-long-mini-projects.

Everyone is optimizing for getting the most information in the smallest amount of time. Algorithm questions do that. The interviewee knows that they are going to get algorithm question, and most places tell them ahead of time what the nature of the questions will be. So interviews should be an easy cakewalk that everyone can pass, but they aren't.
I read this thread a couple days ago and managed to get through it despite the annoying tone.

I think the author is correct now (for the current and upcoming crops) but I worry they're failing to account for larger systemic issues like fertilizer price spikes (and yes I read their fertilizer thread as well), currency issues (inflation, logistics of precursors) and while they acknowledge the shipping issues can kill people they sort of hand wave over it.

I'll admit I'm old and generally just get mad at ideas that challenge my assumptions, but after reading this I'm not ready to believe everything is fine. You have a country torn apart by a war that seems far from over, massive reorganizing of the global supply chain to cut out Russia, and world economic instability as we seemingly hasten the weakening of the USD. The author raises good points but I don't believe everything is fine.
Correct. The languages I learn outside of my day job are languages that teach me new ways of thinking about problems: Lisp and Haskell are two that come to mind. Do I expect to get a job where these languages are used? No. I learned them because it gave me insights for becoming better at my craft. It makes me better at solving problems using the languages actually being used where I work.

Yes, but I think a lot of the meta narratives around crypto currency (used to draw in fresh liquidity) are based around financial "inclusion" - as in bank the unbanked, and own your own keys etc.

But of course anyone that has interacted with crypto currencies, or more importantly the exchanges knows that's not really true. Mostly it's a very efficient means of taking money from the poor and diverting it to the rich. I think jackson palmer of dogecoin called it hypercapitalistic.
