Yes it is. I had to make this decision as to whether I want to work on my personal projects, explore interesting topics or grind leetcode. To actually work on good projects the first step is leetcode.

I have a lot of interesting projects and I can talk a lot about OS kernels and bluetooth. To get to companies working on such interesting projects the gate will be leetcode type judges website. The questions they later ask are rudimentary and none of your effort on going deep into the such interesting topics matter.
It is pretty much right.

Neither country took responsibility for the demand (X), and so the market wasn't aware of the demand, and therefore the generation provided by the market was lacking X. When there is more energy being taken out of the grid than being provided, generators start to slow down. That is, the power is extracted from their rotational energy (inertia), meaning their rotational speed slows down (frequency decreases).

There are mechanisms in place that fix any frequency deviations, but the assumption is that deviations in frequency are symmetrically distributed around 50 Hz (or 60 Hz for you americans). When you have consistently skewed errors (i.e. frequency always being pulled down by Kosovo), you end up with a 'time error' [0].

The time error was noticed fairly quickly (frequency and analogs to 'time error' are monitored in control rooms), but the issue was that no-one took responsibility for it and because it became a political issue it was difficult for other grid operators to step in and fix it.

I'm not sure about voltage being lower in this case. Voltage is a very local phenomena, and it would be very unusual for control rooms to allow voltages to be 'lower than they should be', especially over a considerable time period. To do so they would be in violation of their grid codes.

Ask HN: What'll make decentralized e-commerce profitable for sellers?
Hello everyone! I hope you're doing well…

I'd like to open a discussion about blockchain & e-commerce. We can read a lot about how blockchain is revolutionizing (or will revolutionize) e-commerce.

The idea of a fully decentralized marketplace is amazing: 0 to very low fees for the sellers, no intermediary, more secure, etc etc…

Still today, no marketplace has been successful. Is there really a demand for selling/buying goods/digital goods/services in crypto, the decentralized way?

I'm pretty sure if you ask sellers, they will all be very happy to pay 0 to very low fees for each sell, but if it means your potential buyer's market is reduced by 99%, they will never use it.

I'm talking here about a fully decentralized marketplace, so as a buyer, you'd have to have MetaMask or use your ledger to buy this kind of stuff. It reduces the potential market a lot.

So my question is: what, according to you, would make the opportunity of a decentralized marketplace a real & profitable opportunity for sellers?

Interested in hearing your thoughts!
That page is very poor. It uses every trick in the book to try to make poor science look scientific:

1. Cherry picking: It says HCQ-using countries always have lower death rates than non-HCQ countries, but omits countries like Brazil where HCQ is widely used but the results are poor.

2. Junk sources: To explain why countries are or aren't included in the HCQ using or non-HCQ using groups, they say it is based on how widespread HCQ usage is in that country. For example, it says Brazil isn't included because HCQ usage is mixed. To prove this, it cities sources - which if you are refer to the references - are "high quality sources" such as literally a guy's Medium posted entitled "Hydroxychloroquine: the narrative that it doesn’t work is the biggest hoax in recent human history" (since removed by Medium) and "@CovidCrusher on Twitter". It's just junk built on top of junk. This is not science.

3. Totally ignoring relative study quality: Every scientist knows that gold-standard randomized control trials provide more evidence than any number of weak observational studies. However, this site lists tons weak retrospective studies with tiny sample sizes and minimal effect on outcomes as "Positive" in cheerful bold green while dismissing high-quality randomized control studies with large sample sizes as testing the wrong thing or testing at the wrong time ("Late") or whatever.

4. Ignoring or changing results: If a study disagrees with their preordained conclusions, they either mark it as "inconclusive" or literally just mark it as positive when the authors said it was negative and then add an explanation about how the study authors "were wrong" in their conclusions. Can't disrupt the 100% green "Positive" rating!

Science doesn't progress by summing up bad evidence and calling it good evidence. If you want to show that HCQ works, show a single randomized control study with a large sample size that shows it does anything.

These last few days I've been tickering with wasm3 and Rust as way to run Rust on ESP32. The xtensa architecture has still not been merged into upstream llvm so it's quite hard to run Rust on these MCU.
Doing the sustainable thing is only expensive in the short term. Over the long term fossil fuels will cause more harm than good.
The optimal strategy is to fail-fast.
> It seems like a revisiting of the experience of the Self team between the second and third generation of Self VMs, though the underlying hardware might be just a little faster :) Do you think this tradeoff of peak performance vs interactivity is inherent in Truffle's approach? Or can Truffle realistically aim for the best of both worlds?

> One interesting aspect of the Self VM is that it can save the JIT generated native machine code together with the Self code in the image/snapshot, so that you can load a pre-warmed set of objects. Is that possible within the Truffle framework?

I completely agree. Mario Wolczko, who worked on the Self VM at that time, is part of the extended GraalVM team. So the knowledge and experience is there, it only has to be implemented. The GraalVM team is thinking about ways to support snapshotting and a couple of other things. Their profile-guided optimizations [1] is probably the closest to that and definitely a way into the right direction. So I'd say it is possible to make performance of GraalVM languages much more predictable, maybe to the extent that it doesn't matter anymore for interactivity.

The "media machine" isn't helping produce skeptics, a significant percentage of people will always believe in nonsense.

Astrology, homoeopathy, telepathy, seances, conspiracy theories; the world in awash in centuries old nonsense.

You can't produce evidence, proof, arguments, or rationalization to assuage these people of their beliefs, they are stubborn in them.

Same with climate change denialists.

The ONLY problem is we give them a voice. We don't say have a metrologist and a fortune teller on to hear both sides of a forecast but there's still an insistence on having some climatologist who knows what they are talking about and some random hothead who works at a PR firm for Exxon when talking about climate change for the viewer to "decide".

Nonsense! It takes years of specialized study, the viewer isn't qualified to decide, that's the media's job, to not put on PR spinster horseshit and claim it as potentially valid.

There will always be large pool of nonsense. We need to stop dipping our toes into it and amplifying those voices in critical urgent issues such as climate change. We don't have the time for the bullshit.

For all the talk we do about "bold disruptive innovation" it's all nonsense, we are propping up industries that are killing the planet through nonstop bullshit because we don't want to rock the boat too much on power and profit structures.
Yep, swing is still always within the same timing window and doesn't fluctuate. I mean yeah your 8th note repeating midi hihats with swing won't hit the beat with a perfect precision but the interval between the notes will still remain the same. Beats with swing can still sound mechanic.

The humanizing features OP mentions (like what Ableton live has) introduces random amounts of shifting timings or velocity, which is very different. If you want swing, you'll still have to add that separately.

POWER9 has large cache and can take large memory (at least for when it appeared), but was particularly notable for bandwidth/latency. I think they were the first with PCIe 4, for instance, when PCIe 3 was a bottleneck for HPC interconnect.

The native interconnect in 10 looks interesting.
I doubt that WASM is good as an embedded language, unless performance requirements outweigh the inconvenience.

Dynamic languages are great for experimentation and exploring the system, e.g. a console in the browser is the fantastic tool and web dev people tend to try things there first. By embedding wasm, you are making tinkering with the system you provide less enjoyable for your users.

One could argue that since many languages compile to wasm, you can pick whichever suites you best. But in reality, you are probably limited to languages with thin runtimes, e.g. Rust or C. Otherwise you will end up with a huge wasm blob. Imagine, there are 2 Java extensions, a C# one and something in Python, all running simultaneously. It means 3 different runtimes with a footprint by far exceeding that of the application logic in an extension.

Another burden is the bridging between the host and an extension. Unlike lua or js you can’t pass and inspect objects, the only option is to marshal data as a byte blob. So if you were to pick up a language no one used to write extensions for the particular application before, the very first think you have to do is writing marshalers.

Last but not least, I disagree with the article calling S-expressions ugly and strongly believe in the opposite.

Tax law is what's written in acts and statutes, but also what's developed in case law.

Google's lawyers will claim that Google is compliant with tax law, but until these complex tax avoidance schemes go through the courts we won't know.

Most tax authorities use courts as a measure of last resort, and will prefer to add clarifications to the law and negotiate settlements with avoiding companies rather than spending millions on legal fees for court cases.

Some companies see a regulation and say "that's the bare knuckle minimum expected behaviour that we cannot go below". Other companies see a regulation and say "how far beyond that can we go before we get fined?"

What happens to me is that I find 45 minutes to play a game after I put the kids to sleep, so I fire it up, wait 30 minutes for the latest update to patch since I haven't played in 6 months, then realize I'm tired and go to bed.

Play now. Kids ruin gaming. I'm hopeful that soon they'll be old enough to play with me. ...I wonder what game is good to play co-op between a 40 and a 6 year old?

Recently someone told me his theory. People with thick skin don't need sleep that much. People with thin skin, who are quite receptive, need a lot of sleep.

Partly it's "path dependency" - everything is set up for rectangular dies, so everything would need to change for uncertain benefits. Not just the tooling, but also the design software.

Grid operators have many ways to measure the severity of an outage. In Europe, this is commonly done using the Incident Classification Scale [0].

The term "giant" is not any official terminology, but that particular outage would be considered an "Extensive Incident" (red) due to it being in the T2 category, ON2 category, and possibly in the L2 category (maybe L1, I don't know the Latvian grid well enough).

A lot of people in the industry would say that a 'red' incident is 'giant', as they tend to have high standards for reliability and security.

I'm aware of the naming (I'm English and was educated here), but writing for HN's international audience it's easier to use universally understood terms rather than ones you need to understand our system to recognise. FYI only some private schools are Public Schools (and all Public Schools are private), but the term for all private ones is actually Independent Schools.

And yes, obviously the better education leads to better grades, but that's a completely different issue.

The point in my comment that you replied to is not that independent schools got better grades than state schools this year; it's that their % improvement from previous years to this year is way higher than non-independant schools % change from previous years.

from a very continental european, the following points are making San Francisco very unattractive

- earthquakes and still the same wooden housing which faciliated the burning of the whole city the last time.
- forest fires.
I feel like this time it's different , google (and big tech it represents) will get little sympathy on reddit and other watering holes. Even if the law seems restricting, it's Google who broke the social contract of the internet and turned from a benevolent rent-seeker to a feudal lord. (E.g. check this: https://www.google.com/search?q=money+for+nothing , google just pastes the lyrics and there is NO link to read them on the original site. Even if musixmatch is getting paid , they are made irrelevant and this is a poisoned pill).

Reading the defenses here in HN, I have become personally partial to conspiracy theories that too many paid commenters are among the crowd here.

Plus i don't get what the fuss is about google news. I don't think it's used much outside the US, and even these websites aren't just going to lose all their traffic, because people are addicted to news. They 'll be partly visiting local websites more often, and this shift may actualy be enough to revive the income-starved journalism profession.
Your assessment is the most astute observation I've ever read about what a child means to you. wow.

For me, it's the former where the child will bring me more/higher purpose to my life.

I am a father to a 1yr. I've never felt (never having a pet) unconditional love. My boy (currently ;-) does not care how much I have or make, what I look like or my personality outside of not mistreating him. In return, he gives me a look, a hug, and a kiss that is undeniable unconditional love. My wife's look, hug and kiss are "conditional." ;-)

Before going any further, let me preface with my thoughts about family; I've never experienced a family. I grew up in a broken one where I was physically abused and I ran away at 18. Before having my child in my 40's, I did not want to be a father incase I became what my father was.....resentful, hate filled, neglecting asswipe. Having grown up in that environment, I wanted to make a difference to children who may be in the same or worse situation. So I volunteered to became Big Brother to 3 fatherless boys in my 20's. I grew up...fast. Kids are special and found out just being there for them is good enough to make you Superman. That's all it took. No need to lecture or do psycho analysis to make the "better", but instead just being there was all they needed. PS> the 3 boys became my grooms men.

Does my child make me happier? yes and no. Happiness with a child is a weighted question. Does my child make me happy? yes. Does he make me happier? difficult to answer but I lean towards no.

I think the answers to your question will be weighted by: what age you had the child, where are you in your career, are you happy with yourself and your life, do you love your wife and extended family? Will your child be a trophy you craft or someone you mentor allowing them to grow based on your influences?

Am I happy right this minute? Well, it's 2am, I just got finished cleaning his playarea of dried up breast milk and food, cleaned all of his bottles and toys, prepared meals for him for next few days and to top all that off, he just woke up crying in the middle unexpectedly. No reason why. FYI I'm a fulltime dad.

Is the happiness so strong it can overcome the hardship of doing something that doesn't come with instructions? this very minute; no. Tomorrow morning when he wakes up cooing at you? yes.

Lastly.. omg. Can't wait for him to turn at least 5 if not 7ish for this first Disney World trip and start on the Star Wars series of films :) Having high expectations that he will like the same...I'm over the moon about my potential happiness. I can only hope but never force. He needs to lead the way to his happiness...not mine.

That's an anglo-centric perception. Which countries has Google News been banned in? Spain. China. Germany briefly until Google told the news orgs they'd never pay, so could license their content for free or disappear from News and search.

Newspapers trying to screw Google out of money by pressuring politicians is not an Australia or News Corp specific problem. It's happening everywhere. Really, all it reveals is how cravenly controlled by journalists supposedly independent politicians really are. We always "knew" it, but now we know it.

Factorio has been around in "open beta" for something like 4 years now (and I've been playing it for at least 3), so I suspect it'll be around a while longer.

However, even if the developers stopped updating the game, so long as the game runs on your PC, does it matter? We have people doing crazy things like effectively emulating DOS in Javascript so that you can run DOS programs in a browser window (see archive.org's DOS game section); somehow I don't think you need to worry about not being able to play it in a few years. It's all local by default, so you're not having to worry about someone taking the game servers offline either.
