Similar story with the decision to utilise tab characters in makefiles:

"Why the tab in column 1? Yacc was new, Lex was brand new. I hadn't tried either, so I figured this would be a good excuse to learn. After getting myself snarled up with my first stab at Lex, I just did something simple with the pattern newline-tab. It worked, it stayed. And then a few weeks later I had a user population of about a dozen, most of them friends, and I didn't want to screw up my embedded base. The rest, sadly, is history."

It's great to see alternative to traditional electronics that have much lower carbon footprint. Although I don't know how expensive to process is, it seems to not use any rare metals like lithium batteries and solar panels does.
Hey, this looks great. What are some use cases you looking to solve, with this?
> explain python then. Why is python easier to work with then C++?

This isn't an apples-to-apples comparison. They're very different languages, in terms of everything from memory management to build models to type systems to concurrency to historical baggage.

Python is certainly more writeable than C++, for countless reasons. In terms of maintainability, Python's dynamic types are a disadvantage, but Python is also a much simpler and safer language than C++, which is very beneficial.

> I think you may not agree. But that's just your own unique opinion. In general, I'm the one who's right.

Please refrain from this kind of thing on HackerNews.

> what's your point?

Traceability of errors isn't everything. It's also important for a language to help the programmer avoid introducing defects in the first place.

Neither Python nor C++ do this particularly well. Neither is anywhere near, say, Ada or Haskell.

> Why are you telling me this? Did I say type systems were the only way?

There's no reason to be defensive. Not everything is a refutation.

> Another improvement is to make a programming language that is impossible to crash. Several languages already have this ability.

I'm not certain what you mean here. Which languages are you thinking of?

It's very often useful for a language to have runtime checks that may result in immediate termination, rather than continue with unaddressed erroneous execution. Examples are when Java throws on an out-of-bounds array access, or on divide-by-zero, or on dereferencing null.

> Python is more safe then C++ despite having more holes for crashing and no type system.

We're agreed on this point, although I'm not sure I'd say Python has more holes for crashing. Python is the safer of the two languages. [0] C++ is a minefield of undefined behaviour, [1] Python is not.

Our discussion has not been limited to safety.

I have never read a more apt description of a person. Sure, it’s childish, edgy and inflammatory. See now I accidentally wrote another Musk characterization.
It's generations and generations of hierarchical control, and nothing else. Men who did anything other than advance towards the enemy as ordered were shot, in WW1, in WW2, even again today. That scene in Stalingrad with the NKVD, completely factual. Look up the WW2 battle of Izium which is just one example. They're fighting there again today.

No, it doesn't make sense by western standards. But this is as much as anything a clash of network topologies - hierarchy vs mesh. Our tolerance for constant debates and internecine arguing doesn't make any sense to them either, if that's any consolation. They think we´re stupid to tolerate it, when it's so much easier and simpler for everybody to just follow the vision of the one true leader. To their death.

The problem is, that a lack of oxygene might prevent fires, but not battery shorts and the consequential heat. For treating battery fires, water is the best. Fortunately, water is easy to come by for a ship. So one component to transition car carriers is to add large sprinkler systems, which can quickly cool down a car with a thermal runaway.

Ironically, what is often claimed as a fundamental problem with batteries, their lower energy density than fuel, should make them less dangerous in the case of a disaster in the case of a fire. But the nature of the fire is differently and needs to be handled accordingly. (Of course, shipped cars probably only contain a minimum amount of fuel, but likewise, electric cars would only be minimally charged)
I needed to hear this. I wouldn't say we're in a bad economy yet, but I was worrying about the future a bit.

Our diets are the culprit of your digestive problems, imho. It's not something you cannot change. Humans are slowly losing their ability to digest fiber, and the bloating & pain is there, because your digestive track is not accustomed to high-fiber foods.

Solution is not to avoid fiber, but to add it to your diet progressively. There is a plethora of health problems connected to the lack of fiber in one's diet. I've found that's best to start adding it after few days of water fast, when the "bad bacteria" is weakened.

I don't feel satistied after rice too (and don't eat almost no pasta), I think that fiber & some proteins are necessary for satiety when on plant-based diet.

> what's better - to raise farm animals humanely and allow them to be alive or not allow them to ever exist

We've stolen living space from wild animals and decreesed their diversity - 100 years ago humans and cattle were 2% of weight of the total biomass of land mammals. Now it's about 96%. [0] In other words, we've destroyed the natural habitat and countless animal species, with tens of thousands more threatened by extincion, and replaced them with farm animals, just for our food preferences. [1]

> Even in nature, those animals would have been eaten by carnivores - I don't see myself eating a cat, but I do eat prey animals.

Without us there would not be so many farm animals (obviously). The lion has no other option than to eat other animals. We've got plenty options ourselves, just the will and/or knowledge is missing.

Interesting then that India, which resisted globalization of critical agricultural products, is likely going to come out ahead... The idea that we should solve a problem caused by globalization with more globalization is bizarre. Just as we have seen with PPE, masks, microchips, and other critical goods, relying on foreign countries to put their own interest second is a recipe for disaster.
Blockchain cryptocurrencies rely on the economic incentives of PoW (or something similar) in order to function correctly. Has anybody modelled how the miners might behave under varied circumstances? So far, the incentives seem to be working correctly, with no double-spend attacks happening.
Not a fan of the PM, but the gazette calls out a couple of exceptions, including: "Export will also be allowed on the basis of permission granted by the Government of India to other countries to meet their food security needs and based on the request of their governments"

I'm not expert but I, more or less, follow the war (from my comfortable sofa) and I would like to point some observations.

-We see a lot of Russian bad decisions and result of that decisions but never Ukrainian. That should you make you stop and think.

-If you look only to the maps, and not the news, it's not obvious that the war is going so well for Ukraine, despise they have logistic and intelligence support from NATO.

I could be wrong, but that makes me think that we are the target of a marketing operation.
"When things are bad, keep fighting and don't give up" is a pretty common and often extremely useful military mindset.

From the $billions that the war is costing the west, to millions of Ukrainian refugees, to developing grim shortages of many things which Russia and Ukraine were major exporters of, to surging inflation & other economic effects, to the short attention spans of western news/hype cycles, to regular elections which most pro-Ukraine western leaders are facing in the next year or so...

"Win via attrition" is probably too optimistic a phrase. But it would be pretty realistic for Russia to say "our least-bad option is to keep fighting, because our enemies' situations will deteriorate faster than our own".
Disclaimer: I may be absolutely in the wrong here, as I may be missing some fundamental economics knowledge.

From my understanding, inflation is not really a property of the currency, but a property of market in which given currency is used. It's not the USD that loses value, it's the specific prices that increase, not that some products get cheaper. If some country suffered from hyper-inflation, they may start using USD instead of their original currency, and local products would end up with a different inflation in USD, than USD in US.

In Bitcoin and other crypto, I doubt there is huge market which has prices set in those cryptos - they are used as a courier money for markets in specific fiat currencies, like USD. I doubt people pay 0.001 BTC for a server, they pay $100 but in BTC.
You just don't understand Russia culture. Americans live in lala land, they have no clue.

What communism was about in Russia was taken the best people at every single sector in Russia and just exterminating them. In the 1930s over 50% of Dombass engineers were put out of work!

Most of them were later killed. Anyone that had the minimum entrepreneurial spirit(kulaks) was exterminated. Their children could not study on public school, they became pariahs even without access to food.

Their families were humiliated and deported to the other side of Russia.

Over 50% of the economy was the military and police State to control the population that naturally reveled. When workers did strike, the Soviets took hostage of their families, then after the strikes were over the leaders were killed.

Merchants, unions and the Church were also exterminated. All communities gone so nobody could go against the power.

With Putin all the power remained in the KGB, Putin came from it, all the oligarchs were Putin's friends from the KGB. The Church leader was also a member of the KGB.

Ukraine by the way has the same History, the same System and corruption as Russia by the way, but they are fighting for their land, and have the support and training of the West.

Millions of Ukrainians died from starvation with the Soviets while Stalin exported grain. It was on purpose against peasants as punishment.

Americans admire successful people. Russia culture is the polar opposite. Think for a moment about that.

How does this sound:

Optimizing for ever higher economic prosperity has so far had the side-effect of ever higher economic inequality, in no small part because only a small number of people are able to succesfully get rich off of moments of instablity.

Optimising for stability means less homless people on the streets (which is an appaling situation in US which still despite that wants to call itself a first world country) because a larger part of society can plan their futures and actually have those plans come true. This also necessary includes socialised healthcare and schooling, for the same reasons (which again probably won't happen in the US for the forseeable future).

> ...the Russians have had plenty of time to read the board of enquiry report on the sinking of HMS Sheffield.

At the start of the war, Russia knew that Ukraine had an anti-ship missile in development but not ready for deployment, so they didn't take precautions. Clearly, the Ukrainian missile developers put in some overtime. After the Moskva strike, Russia bombed the missile factory and moved their ships farther out.

This whole “what matters is the founder” idea really discourages me. It’s such a VC perspective. The VC has a flock of people they pick from to invest in and if your traits doesn’t fit the necessary requirements you shouldn’t start a startup. And I’m sure it’s true too. It’s just that it feels like if you don’t have the grit etc necessary you’re just out of luck and out of this club and it’s not really something you can work on. (After all if it was something you could improve then it could be taught but PG et al seems to think - and I think they’re right - that it’s an innate thing.)

I did something similar a year ago at the company which I work, I basically wrote a middleware that intercepts all the requests(express JS) and writes to a OpenAPI YAML file. It diffs previous requests to see which parts of the request path could be variables.

>An EDL is not required to fly domestically, which is good because only 5 states offer the option. An EDL includes the Real ID benefits which includes domestic travel, but also acts as a passport when traveling by land or sea with Canada/Mexico/some Caribbean nations.

Yep. Which is why I said:

...I wanted to trade in my license for an "Enhanced
Driver's License"[0] (EDL) which, *among other things*,
will be required for domestic air travel[1] in a year or
so.

Upon reflection, I can see how that kind of puts the cart before the horse, but it isn't really incorrect as an EDL incorporates the RealID.

I suppose I could have clarified that the EDL provides RealID and additional functionality as you describe, but I figured that "among other things" and links describing both RealID and EDL, folks could find out for themselves what "among other things" meant.

Perhaps that overestimates the reading comprehension of some folks, but I prefer to give people the benefit of the doubt and not assume they're morons.

Perhaps that's a mistake, but if so, it isn't my first and won't be my last.

I thank you for clarifying and I'm sure the morons out there will thank you for your pedantry as well.

I'd further point out that this was just a real-life example of a service which must be provided in person and not online and my experience with scheduling an appointment. It could just as easily have been any of several different services which require actually going to the DMV, but that's the one that is relevant to my life at the moment.

As such, even if I'd claimed that an EDL gets me free blowjobs at Federal buildings, I still made the point I was attempting to make.
