I'm not well versed, but I don't think your assumption is accurate. At time t, the sum value of all money depends on who is holding it. It seems to me that $1M isn't the same to everyone - if I'm dying unless I get a surgery paid for by that money, its worth more to me (I am willing to pay more over time to access the money now) than to Bill Gates.

Or a business. Give $1M today to the right business and it'll be worth more than if you give it to your local neighborhood MLM. While the change in value is realized over time, the net present value of the money varies depending on those future deltas.

Am I way off here? What I'm trying to say is that current value is derived from future value, so the sum of money at time t is dependent on how today's money is distributed and grows in the future.

I recall a blog post or article posted several years ago, somewhere, that discussed the networking consequences of lightspeed being an upper bound for bandwidth. Unfortunately "lightspeed networking" is not a unique search term! Does this ring a bell with anyone and does anyone have a link to that article?
30 year decommissioning is a very pessimistic assumption. Also most new nuclear plants have operating lifetimes closer to 80 years than 55.

You also have to adjust for the overproduction necessary to make intermittent sources a reliable primary provider of electricity. In far north or southern latitudes, angle of inclination is such that solar panels collect ~70-50% less energy than near the equator. This gets worse with seasonal fluctuations, which are more extreme the closer to the poles you get. Add weather on top of this and it can drop even further.

This might not seem like too big an issue, but keep in mind that most of the world's electricity consumption is in North America and Europe. These places don't have as good weather for solar.

100,000 acres is roughly the ratio that the article came up with, a factor of 75.

That's an implementation issue with capitalism. I was referring to implementation of a service that provided accurate route distances for drivers.
So are you claiming Oklahoma, Arkansas, Louisiana and Missouri have experience state wide blackouts similar to those found in Texas in recent days?

Or are you saying these states have experienced short term blackouts?

I don't think there is an electricity grid in the world that is immune to short term blackouts.

Ok, but I was asking about a single space laser vs a single fiber, not the theoretical limits of many of them.

Space is pretty big, lasers are pretty narrowly focused, and not many people have lasers in space yet.
I don't have any clue either but I think Google is changing from a young company to an established one (think Apple). Before, they were ambitious and actually worked for the people, but now, they are unstoppable so they ought to do what they want.

It's a shame that they are now even more profit-seeking than seeking customer's satisfaction.

They also closed many services which were not profitable for them like Poly, Daydream and are now even removing the free backup option in Google Photos.

I think they now know they have became a strong company. They are unstoppable.
I wasn't very articulate there, but by a procedural or workflow aspect I mean something like: the workflow will lead you through a series of actions that will make it physically impossible or unlikely to [do the dangerous thing]. This is different than [system can't do the dangerous thing]. It's also different, and safer, than relying on user actions outside your control.

Example: I have a mechanical system moving fast with enough mass to hurt the operator, so I put the control on the other side of the machine (i.e. machine body between person and the dangerous part), and require the operator to hold a switch "on" for the entire time the machine is moving.

This doesn't make it impossible for the machine to hurt the operator, of course, but it makes it a lot less likely - and it doesn't rely on training at all.

While you can also rely on training aspects like you describe (a good idea!) it's not the same thing.

I don't know aircraft, so I don't know if there is something equivalent but I wouldn't be surprised. Anything you simply have to do with two hands on disparate controls?

Psychedelics are not without risks, but the risks are for me a deal breaker when they are illegal.

There are too many ‘designer drugs’ out there with unknown properties that are sold by misrepresenting what they are.

LSD25, psilocybin, MDMA, DMT these are drugs with known risks and side effects, and there has been legitimate investigation into their benefits. It would be great if we could legally continue to gather data.

So far, it seems these substances are arguably much less dangerous than many illegal substances. I would be in favor of legalizing all of them.

Decriminalizing seems to be a necessary step in that direction, but it doesn’t allow for quality control. Legalization allows for real and enforceable disclosure about what I might be putting in my body.

I hope we get there someday.

Edit: and possibly less dangerous than some legal substances.
I have been amazed, and also disappointed, by the amount of people that want this to be the fault of “stupid conservative Texas” and absolutely refuse to even entertain the idea that anything other than “Texas is dumb” could have been a contributor. Even in this thread, the number of comments that adamantly insist “this is only a Texas problem”, despite facts to the contrary, is astounding.

That goes the other way around, too (lots of conservatives immediately blaming windmills etc).

It reminds me a lot of the Reddit posts whenever a bombing happens. You’ll see people from both sides rabidly hoping that it was a Muslim suicide bomber or a far-right extremist, because if that’s the case they can use the event to push their political agenda. It’s sickening, IMO.

There surely is room here for criticizing Texas GOP policies, but they aren’t the only problem here, and if we actually want to fix things we need to stop playing these ridiculous partisan games and be honest with ourselves with the full picture of issues.

I don't understand the obsession with ClickHouse. While it seems like it fits this particular use case, it still deals with the same limitations and challenges of columnar DBs. Your queries will be very fast with counts/averages, but there's a tradeoff with other functions: inserts are efficient for bulk inserts only, your deletes and updates are slow, no secondary indexes...

While Clickhouse can be lightning fast, is it really designed to be a main backend database?

Hopefully someone will correct me if my numbers are off, but this is what I remember from a conversation with a nurse:

A vial contains 0.24 mL of concentrated vaccine, which is then diluted with 1.8 mL for a total of 2.04 mL. This is enough for six 0.3 mL doses, or 1.8mL - which leaves 0.24 mL remaining. ie. not quite enough for a seventh 0.3 mL dose.

So.. what is the method to obtain a seventh dose? The article does not say.
You can't really compare the US to the EU though and this isn't going to the US supreme court.

You don't need to be successful in stifling competition to be anticompetitive so market share enough to be a "real" monopoly is likely irrelevant. Trying to abuse your position is enough as Google felt with Google shopping and Android. "Capable of having, or likely to have, anticompetitive effects". In Android, "it is sufficient that the conduct tends to restrict competition or is capable of having that effect".

In my opinion Apple is going to be hit hard in the EU. Fans of Apple always roll out the old "but the app store is much more profitable" which is a truth that will IMO come back to bite Apple when refusing others fair access and thereby "restrict competition".

>that's just more evidence of my point that Apple and Microsoft are different situations and aren't comparable.

I agree they are very different and not comparable.

Ask HN: Harder Software Jobs
I'm leaving this question a little vague intentionally to solicit a wide variety of interesting responses. I graduated from college with a CS degree in May 2018, and have been working as a SWE at the same FAANG company since that summer. I like my job and am pretty good at it (have consistently gotten quite good performance reviews), but also find it fairly boring. I basically implement very simple business logic and glue APIs together. I do not work on any challenging technical problems and my manager discourages us from thinking too hard about things like performance in favor of quickly making progress and keeping the code very simple. I understand there can be a lot of value in working this way, but I am getting tired of it and want to move to more technically challenging work.

This question is also somewhat inspired by seeing the coverage of the Perseverance rover and reading about some of the serious technical challenges involved in software work for these applications. With that in mind, what recommendations do HN users have for jobs that I might find more challenging and engaging? Should I look more at embedded systems work (I am decent at C++ but would have lots and lots to learn)? I would prefer to move to another team within my current company but could definitely try to find another job too.
Aren't those the same things conservatives continually talking about and trying as Republicans to cut and get rid of?
> Right, as evidenced by the extensive storage infrastructure being deployed /s.

Invalid argument.

> The US has 25 GWh of storage, as compared to an hourly electricity consumption of 500 GWh. Literally less than ten minutes of storage. Almost all of it hydroelectric, which is a big infrastructure project on par with building nuclear power plants

Irrelevant point.

Storage was marginal in the past because there wasn't much of a business case for it. With renewables crashing in price and fossil fuels being phased out, that is changing. There are now strong market forces pushing development of storage technologies. Your insistence of carrying over the market conditions of the past into the future leads you astray.

Well, there's "green-screen" VT100 terminal apps, and then there's 90's Vintage Java/oracle-forms UI's and then there's modern applications designed with informed UX approaches.

The terminal apps, at least, have some history behind them and properly trained folks can be very fast with them.

But we're talking here about shitty early Swing-apps (or Oracle forms). If you've ever used one it can be incredibly frustrating. Moreover, people are usually just tossed into a role where they have to use these M-F-ing interfaces with no training. Who makes a table with cells too small to fit their content and where you can't resize the table? Oracle. That's who. And they're paid for it like you wouldn't believe!

I really like this line of thought and I think your instinct is very good here.

Remember - if you are in the middle of a potentially failing array, every single bit of parity data is pure gold and if you fail out a drive, that drive worth of parity is gone forever.

So if you fail out a drive but it was actually weird bus errors getting spammed by some other drive that is actually failing, now you're in trouble ...

Minimum-wage earners are people too, not mindless drones. You have there colleges students, second-income parents, people trying to create their own business, people working in the arts, volunteers.

Do the plants actually need the full strength of that red and blue light for optimal growth though? I thought the comment above mine was implying that they don't.

So my proposition was that if we started with, say, midday sun, maybe we could divide that up (in brightness, not just by spectrum) to cover a larger area (multiple floors in this case).
> It's amazing how people have adopted passionate stances despite not living here or knowing anything about power grids.

The people who started publicly adopting passionate (and quite obviously false) stances despite not knowing (or worse, knowing but adopting the false stances anyway) about electrical grids live in and have responsibility for Texas, the crisis, and the response to it. And that's what turned it into a tribal, partisan political issue.

You Texans don't like that, you should consider it next time you find yourselves in front of a ballot. Or sooner; effective political engagement requires more than voting.
These questions that you have to study for and the leetcode problems are all symptoms of a total lack of licensing in this industry. Other engineers, lawyers, CPAs, doctors, etc. all clear some exam and have regular requirements for maintaining their license. Since there’s no trusted third party for companies to assess some baseline of competency, we all basically have to take a license exam and have an interview for every company we apply to.
As someone who is completely ignorant to this field, I found this very readable and interesting. Thanks for your work!
Not. Nowhere has it done well. It's just too complex with too many interdependent parts. Construction has proved to be beyond the competency of those trying to build plants. And now, it's just too late. The iteration time for nuclear designs is measured in decades, going up against renewable and storage technologies iterating in periods of a few years.

Fusion would make fission look dead simple. If fission reactors cannot be constructed on schedule or budget, how bad would fusion reactors be?

From a miner's perspective there's little incentive (in cost difference) to get a mining specific card that doesn't hold its value when the mining craze is over compared to a general card which can be sold on the seccond hand market if necessary.

You asked if extreme cold weather had caused problems in states other than Texas. It did, and I commented so.

I don't get why you keep bringing up minors because they add nothing to the discussion. The UK doesn't have minors, yes I get that, nobody said it does. I'm saying from all the descriptions here it appears what you call "degree" (EE, ME, etc.) is what we call "major [field of study]" in the US. Whereas in the US the term "degree" refers to BS/MS/PhD/etc. Just a terminology difference. Some colleges in some universities in the US require you to determine it upfront, some let you do that optionally, some actively prevent you. (e.g. some colleges let you take a year or more to decide whether your major is English or Biology...) Apparently in the UK they all require you to declare it upfront. Whatever the policy is, the timing of the decision/determination doesn't change what it is, and again, even if it did, most schools let you if not require you to declare your major (what you call "degrees") in the beginning.
It's rather outrageous that a plant can be illegal in the first place.

Yes, nuclear hardly costs any more to run at 100% capacity than it does at 50% capacity. That's why decarbonization with renewables as a primary source doesn't make much sense.

Solar and wind are both intermittent. Wind is dependent on the weather and experiences situations with near zero production for long stretches of time. Solar is also weather dependent, and has day-night cycles on top of it.

This is fine if you're not actually looking to decarbonize a grid, just trying to opportunistically shave off carbon emissions here and there in a primarily fossil fuel grid. But if you're actually trying to eliminate fossil fuel use this is not a good approach. Theoretically we could store excess energy, but no scalable storage solution exists at the moment. That leaves nuclear power plants to serve as a dispatchable source. But as you pointed out, nuclear plants are just as cheap to run 24/7 as it does to run intermittently. So why not just build the nuclear plants and skip the renewables?

Sure. For sake of argument, let's assume I can't make sense of the article. So, what does it say? Outside of "look, graphs", "What will the future bring", and "I don't have answers"?

It's not asking any extraordinary questions not on anybody's radar. It's not providing any answers, or even insights. It's devoid of useful content. There is nothing to actually critique.
