The former is easily achievable, if the towers are profitable to install. We only have to build them one at a time, and if a collection of 10-50 is cheaper than a peaker gas plant, then the utility decommissions the latter and builds the former.

The latter is simply not necessary. There are a number of ways to solve the last few percent, including leaving a few peaker plants running; presumably, we'll do all of them.

Those peakers can be carbon-neutral, because it's possible to run CO2 extractors. One implication of our renewables is that there are times when they generate power considerably in excess of requirements: using that energy to sequester carbon is plausible.

Of course, if we got over our civilizational horror of nuclear energy, we could solve this problem in a thorough and boring way. I'm not holding my breath.
You lost me at "assume an optimistic scenario where vendors are able to properly address the security implication".
Ideal, I guess. Though I don't see how that could ever be possible.
The numbers for Norway makes no sense at all. Cheapest is supposedly $0.62, but you can get 1GB for less than $0.0046, if you pay for unlimited usage and coverage is good so you can average 200 Mbps.

And the average is much too low for 1GB if this was supposed to not include transfer as part of a larger package.

Either way, the numbers makes absolutely no sense.
Show HN: An embeddable Lisp implemented in Rust, supporting native interop
On the one hand, on Linux with the clone system call, you actually can have a "thread" that shares memory, file descriptor table, etc, but not working directory (or chroot):

If CLONE_FS is not set, the child process works on a copy of
the filesystem information of the calling process at the time of the
clone() call. Calls to chroot(2), chdir(2), or umask(2) performed later
by one of the processes do not affect the other process.

On the other hand: what you say is true of posix threads, code built atop clone is unlikely to be portable, etc, etc.

More generally, it's very much the case that the process-global nature of the working directory makes some things tricky. On the other hand, there are ways around that.

If the only pieces that need to reference the working directory are processes you're spawning, the answer is simple - carry a description of the intended working directory through your computation, and actually chdir between the fork and the exec.

If the only pieces that need to reference the working directory are things you will be writing as a part of the current project, you can use "at variants" (openat, fstatat, unlinkat, etc).

You can stitch these two together as needed.

What's awkward is if you need to use library code that references the current working directory and does not use "at variants". In that case, you could play some awkward game with a mutex, setting the cwd only for the duration of individual operations and restoring it afterward (although that does require knowing when these operations may be performed).

Or you could fork your process along the lines you need to draw. Splitting your view of memory raises questions of IPC. In particular, if you want to pass language-specified data structures that gets complicated - particularly if they may contain references. If you can get away with treating everything as passing streams of bytes over actual pipes, it's pretty straightforward. To my mind, this is probably most of what's meant by "shell-script like", and while you're recreating part of a shell, it's actually not very much of a shell, it should be well contained in the library, and you have room for a much better story around things like error handling. I don't have a sense of whether any of the particular libraries discussed here are actually addressing exactly this issue or whether they actually do a good job of any of it.

Yes, exactly that. Solar radiation causes crystal defects.
Ask HN: How do I learn how to learn hard things?
I'm about to graduate this December and I truly feel like I have an issue with learning complex topics. I'm a CS major for context. After my freshman or sophomore year, I realized that I'm pretty solid with reading, memorizing and spitting back out info, but taking info/frameworks and applying it to new problems/contexts is where I fail. I feel like my brain is hopelessly linear/rudimentary when I try to solve problems, if that makes any sense. Since realizing that, I have not fixed this gap, I've just been barely getting through school. I seem to have a...hill that I need to climb before I get into a focused, deliberate state of learning and applying hard things. When I do manage to complete complex work...it's poorly done/organized/thought through. This is likely a result of a combination of poorly selected shortcuts in learning/getting through classes and doing the bare minimum at certain points. I valued getting through school over thoroughly understanding what I'm doing and maybe having to retake some more classes. I'm at a point where this weakness has shown/will probably show in high level classes and potentially in whatever job I start in January. I'm not sure if I'll ever be someone who "loves to solve problems" or "loves getting into the details", but I'd like to be able to get to that kind of mindset when necessary.

Now, I think can have a bad to mediocre career at this point, but I don't think I'll achieve the goals I have unless I handle this issue. So ya - how do I learn how to learn hard things? Or how do I learn to turn my desire to learn/apply certain topics/do certain projects into meaningful action? If anyone has gone from a similar point to actually becoming thoroughly competent - I would love to hear how you turned the ship around.
TL-Verilog
By comparison, a plant of the same design as the Vogtle plant was built in China at a cost of $7.3B, yielding a cost of $3.17 per watt of output [1] - under 1/3rd of the solar cost with the required overproduction. The Vogtle plant is the first of its kind in the United States. First of a kind plants typically cost about twice as much as subsequent designs.

Furthermore, you're not including the cost of storage for your estimates on solar and wind. Even 12 hours of storage represents a staggering amount of storage - that's 5.75 TWh given the US's average daily 11.5 TWh consumption. Costs per KWh are still on the order of hundreds of dollars per KWh. At $200/KWh 5.75 TWh works out to over a trillion dollars. And this is a recurring cost, as storage needs to be replaced. Hydroelectric storage is cheaper and doesn't need to be replaced, but is geographically limited. Even then, it's not that much cheaper at $100-160/KWh [2]

Yes, renewables work if energy storage becomes effectively free. But energy storage is anything but free.

Hehe... wish I had a link for you, I went digging around the internet with some serious Google fu and didn't turn up much. The MIT guys were l0pht, but I couldn't find any stories linked to them.

The original story was in a 200 ish page library book I rented in 2004 or so, and I imagine the publishing of that book was in the early to mid 90s based on the tech and artwork involved :) It was at Half Hollow Hills public library, which has since been demolished!

Your point is correct and important; I like to think of it as the proverbial "speak softly and carry a big stick".

There's however one key, pivotal change that happened during the wartime - scaling out the manufacturing and logistics. Primarily USA, and largely Great Britain and USSR, scaled out production of weapons, vehicles & materiel, subassemblies, and certain raw materials by factor of 10x or even 100x. Same with the related logistics. This was a huge undertaking[1], required high level of engineering, manufacturing, and managerial expertise. If people like GP only got into weapons & materiel production in the wartime, they'd still contribute greatly to the military effort.

That might actually be an odd but perfectly rational dating strategy for females that want to make absolutely sure they are not being cheated on, to be in a relationship where they have all the power, because they damn well know how hard it would be for that guy to find another partner.

Of course you have exceptions like this, for all kinds of reasons. There are people who fetishize morbid obesity or amputation. That doesn't mean that for every morbidly obese amputee there's a matching partner.

I was a member of a small self-help group that practically disappeared in two years, because everyone was too busy doing their awesome projects, and didn't have time to post. That was when I realized that self-help groups that persist for too long are suspicious.

Okay, in theory, the members that solve their problems and leave could be gradually replaced by new members, so the group could exist for a long time. But in practice, it would be unlikely to have the members sufficiently balanced, so the evaporation of the most successful ones would increase the fraction of the ones who are unusuccessful for all kinds of reasons. Also, trying to grow a group is in tension with vetting the potential members.

Best ML Book, Imo
For me, the most magical thing about the small local bookstores is the people working there.

Just getting into one, chatting with people genuinely and deeply passionate about what it is that they are selling. Having a coffee, talking about a book I read, what aspects I liked, philosophizing about the topic in general and getting recommendations what to read next based on that has beaten at least 10x any 'modern' and automatized approach I have ever seen.

But I think that is a situation where a lot of small shops, whether they sell books, music instruments, clothes, food, etc. are in. If they grow too big, the immense value of personal advice and interaction gets lost and if they are too small the people might not be able to make a living.

The blog post describes him trying to catch up the deficit from vacation days away from the Internet.

StackOverflow has done a great job with the points incentives. As noted in this blog, the daily cap on points is important - it's valuable to put the brakes on people who are too into it and in danger of burning out. Candy Crush does the same thing.

A few years ago, I asked Joel Spolsky what he might do differently: he mentioned that getting to a million points is a magical number for many people but it's too tough on StackOverflow. If the point system were set up to be more generous, more people could achieve this milestone and more valuable contributors would have this somewhat arbitrary but enjoyable recognition

I believe California does, but the scale of the problem is completely different compared to a sate like Florida. California has 2.5x as much land as Florida and a significantly higher percentage of the total land is wilderness or otherwise undeveloped.
True, but no other energy source has a mode of failure that makes swathes of land unusable for essentially forever.

But the main argument against nuclear is "organisational" so to speak.

For some reason nowadays the more liberal a country is, the less success it has in rolling out nuclear.

Perhaps it's the additional incentive of being able to reprocess waste for weapons that's so alluring.

You can distribute them on any other site. Somewhere like github would be happy to host them. Power users already know how to use those sites to sideload extensions. I don't see what benefit is going to be had from distributing an unstable extension that can potentially break every update, break the entire browser, steal passwords, keylog you, etc, alongside all the other stable extensions.
I was going to suggest a variation of this idea that I learned about here on Hacker News and have applied successfully since:

Try to stop on a bug or error.

Same reasoning you cited with a bonus: when you come back in the morning, you'll have an error message to help you quickly pick up where you left off.
> the occupants are (literally) empowered when the grid is mismanaged, as in California.

The California blackouts started around sunset, when solar dropped off the grid. Building more solar without an appropriate amount of storage just makes the problem worse.
How much cleaner is solar thermal than PV? I assume that depends on how dirty it is to produce the metal for the turbines (steam or air, in the case of solar towers).
> They don't fund exclusives, they buy exclusives after they've been completed.

I see this a lot but I have yet to come across a good explanation of why this matters, could you explain? From my point of view it doesn't make a difference when the developer gets the money, an exclusive is an exclusive.
It seems with Nuclear we have always underestimated the risk in the risk/reward nature.
Seriously. My partners school was saying they will open this week (on top of COVID, of all things) if the AQI is not in the red. The sensor they're using is indoor. This website is actively doing harm with these configurations, granted, so is the school administration.

COVID is bringing out the worst in all parts of our society. It has been such a stressful time, and I am someone who has some financial security. I can't imagine how tough things are on the average American right now.

Stay strong everybody. We will make it out of this.
I have friends all over NYC and Long Island and Jersey City, plus colleagues, their friends and family, etc etc. Collectively we know thousands of people.

The CDC officially became aware of coronavirus on Jan 1, and the first documented case in the USA was Jan 20. Now, we could have all had the flu, but really the flu doesn't have such a horrible deep chest cough like we all had in my opinion.

Given that some people say coronavirus was circulating as early as November 2019, I think we all had something more than the seasonal flu. By march 2020, the only people I knes who were sick were in nursing homes.
The competitive bits are over the 200 points a day (you get passively from a certain point, I think it was about 150K for me).

If you answer a question the +15 points you get for a correct answer count towards the limit. Jon Skeet's and Gordon's game is very different from most users and it's on those margins.
Shameless plug to a free service I made, https://stox.dev

It's essentially a stock screener. It lets you write arbitrary queries on over 300 fields and ratios from the firm's accounting statements. Its the opposite of algorithmic, but helps you narrow down the field of stocks you may find interesting (eg. Low PE, high book value, certain industries, etc)

This is largely theoretical. The Kemper demo plant is a disaster in terms of massive cost overruns, many years of delays, and inconsequential net energy production. They ultimately abandoned the project.

I've been seeing an uptick of anti-renewable sentiment, either coal or nuclear is probably doing a media buy at the moment.

So much of what we see in news outlets are driven by dedicated PR drives, and these dying industries are trying to hold on, or trying to unload stranded assets on the next biggest fool.

This is very frustrating. Agreed, they should turn them off by default.
A thing that they are good at however, is lowering temperatures in cities (compared to e.g. stone surfaces which store the warmth of the sun) – this alone might be a good reason to look into green roofs, given that we just passed the point of no return for Greenland's ice sheet recently.

It takes the same amount of energy to melt 1kg of 0°C ice into 0°C water as it takes to heat 1kg of 0°C water to 80°C.
After watching it again I agree with you now. Either way, the pace of the cuts are still jarring.

Interestingly some of the cuts do jump forward in time, but they zoom in on the same subject usually.
We do have a govt, it's just the elected parties that can't agree on how to govern together so in the meantime there's some interim setup. Or something along those lines. It's such a non issue that nobody even notices. I wonder if anyone at all is impacted.
