The economic notion of value is wealth-weighted.

It's true, rationing would struggle to maximize economic value by allocating to well-off hoarders and scalpers. But it also wouldn't properly incentivize consumption minimization, warehousing, and production, and that's the real rub. It's complicated. Just be careful about fudging "economic value = value," because this seemingly harmless approximation actually smuggles in an assumption on the scale of "free market can do no wrong."
>If you were to gamble, what odds would you place on the idea that there was no evidence evidence for the warrant?

I'm getting trolled anyway. The affidavits have been released, they're a joke. Which is why Joel Ensley (recognize that name) revoked the search warrants. Seriously, you don't even seem to know the basics.

So is force. Two maximum force systems should also end up with double the force.
Amazing! That's the one.
Texas utilities are regulated, in fairly similar ways to how the German electric market is regulated. Shortages can drive spot prices for electricity extremely high for short periods of time (over 700 euros per megawatt hour last august in Germany).
I work on Typesense [1] - historically considered an open source alternative to Algolia.

We then launched vector search in Jan 2023, and just last week we launched the ability to generate embeddings from within Typesense.

You'd just need to send JSON data, and Typesense can generate embeddings for your data using OpenAI, PaLM API, or built-in models like S-BERT, E-5, etc (running on a GPU if you prefer) [2]

You can then do a hybrid (keyword + semantic) search by just sending the search keywords to Typesense, and Typesense will automatically generate embeddings for you internally and return a ranked list of keyword results weaved with semantic results (using Rank Fusion).

You can also combine filtering, faceting, typo tolerance, etc - the things Typesense already had - with semantic search.

For context, we serve over 1.3B searches per month on Typesense Cloud [3]

GLASS-z12 is way in front of the CMB.

You have to be careful with what you mean by "distance" at cosmic scales. Space is expanding with time, and there are several different definitions of "distance" that give very different results at cosmic scales.

The best "distance" measure here is simply redshift. GLASS-z12 is at redshift z=12, as the name suggests. The CMB is at redshift z=1100, so it's father away.

In fact, for very straightforward physical reasons, no light can reach us from beyond the CMB. The universe was opaque before the time of the CMB, because it was ionized and dense. Before the CMB time, photons could not travel very far at all before they hit an electron and were scattered.
>Maybe a XOR decryption key for the first set?

Gigabytes of keys? I hope Apple isn't wasting tons of bandwidth to achieve information-theoretical security that's no more secure than than 256-bit AES in practice.
Yes. And only some people, and in a context of power costs having gone up 6x normal. I'm using it as an example of another mechanism but its the corollary of rich people can pay: you can pay poor people not to use it, instead of just letting them have to not use it.

And, you can profit less from the situation. Utility profits should tend to the longterm rate of return, not the surge pricing rates of return. Under surge pricing there are perverse models where it pays the utility not to generate to earn better revenue per cost of unit electricity made.
The author mentions in the thread that the boot time they measured on the device was 28 ms and 7% of it (2 ms) was spent sorting.
Article repeatedly states mandatory withdrawals begin at age 72. The correct age for the overwhelming majority of people who have not started mandatory withdrawals is 73.
They explain this further on in the Twitter thread. It's the portion of time spent sorting the array of system calls during boot. This didn't used to matter when it took longer than a second to boot up, but now that the boot times are in the sub-second range, the amount of time spent sorting the array of system calls ended up taking up a notable chunk of the time spent booting.

Might not matter for the things you care about, but some people certainly do care about boot performance.

As two persons have already asked:

> When the FreeBSD kernel boots in Firecracker (1 CPU, 128 MB RAM), it now spends 7% of its time running a bubblesort on its SYSINITs.

> O(N^2) can bite hard when you're sorting over a thousand items. Time to replace the bubblesort with something faster.
Boot time was reduced by 2ms, from 28ms to 26ms. Hardly 100x speed.
The article brings this up towards the end,

"These [eddy current heaters/induction heaters] are comprised of a magnet mounted on a rotating shaft, and can reach temperatures of up to 600 degrees Celsius. Using eddy current heaters, windmills could provide direct heat at higher temperatures, making their potential use in industry even larger."
Redesign: I've responded to the redesign argument in another comment. It's easy to find if you search the page for "rare event".

Mobile app: this is addressed in the article.

Naming: Usually most naming for different parts of pages is handled by the design(er), but even if not, once you have an approximate naming convention for parts of the site, naming becomes easy. And the stakes for these names aren't that high, because you are only scoping everything down to a single page, so global consistency and precision in naming is not that imporant. It just needs to be enough for someone to understand what it most likely refers to on this page.
Do "feature phones" even use feature phone (=embedded, RT) OSes anymore? I assumed they all used KaiOS or Android under their easy-to-use UIs.

Not anymore.
Until 2021, consumers could choose providers who bill them at the wholesale rate, as weird as that is.

As a result, the last time this happened, consumers were exposed:
https://www.nytimes.com/2021/02/20/us/texas-storm-electric-b...

Those plans are now banned, i believe.
You're not wrong in principle, but in this case these prices are not directly passed on to consumers. The downside of that is that consumers have little incentive to conserve.

When we do have rolling blackouts it's not fair because houses that happen to be on the same substation as a hospital never get blacked out while others suffer for hours.
Does it though?

The main element of surge pricing is that it's temporary, which means not-important-for-non-emergencies
People aren't on plans that expose them to spot pricing. No consumers directly paid more because of this spike.

It sounds like the slogan of an AliExpress GPU brand.
> The price is listed as mega watt per hour but the average house uses just 3% of a megawatt per day.

It is listed in megawatt/hr because that is how you meter electricity. Megawatt/day is not a standard I have heard of.

> Which would be very annoying - though realistically dont know if it deserves the doomsday comments.

I don't see any 'doomsday comments' in the article. What is alarming though is that these prices are happening, and all it takes is a few generation facilities to go offline for something like that to become long-term. Essentially, if the prices are hitting the cap for any amount of time, then the system is one misfortune away from catastrophe.

Engineers don't design bridges to hold the max they think it will need, they engineer it to hold multiple times that. Something essential operating at max is operating extremely poorly.

Funny, I'm in New Zealand and I'm guessing you probably aren't, which means Gateway must have done the same game bundle around the world. Did yours also come with an exceptionally crappy two-button gamepad by any chance?

Redline Racer felt really smooth with great graphics for the time. I loved how eventually you started unlocking ridiculous gimmick bikes like a hover bike and a dinosaur. I don't think I ever quite unlocked all of them.
Then you need to pay people who can’t afford it. Thousands of houses. Each needing a custom install. You could build a solar power plant instead probably which would be better.

The storage could local using batteries or remote using lakes, flywheels, lifted rocks, hydrogen? etc.
100x faster on 7% of Firecracker boot

So ~5ms speedup
I agree. When I am scripting, I want to have quick feed back loop. You can't really do that with Go because it doesn't have as good introspection and debugging capabilities as a scripting language like Ruby and doesn't have exceptions, which means that error handling is more verbose than necessary.

Also, I like being able to make modifications on the fly, so doing something in Ruby, I can just open the file make adjustments and I am done. With Go, I have to compile it and move it back into my path which is really tedious.
You can't have consumer plans that bill at wholesale rates anymore in texas.

After the last time consumers were caught out, they banned it in HB16 in 2021:

That’s, of course, assuming that those 10 people would have gone to that specific news site and read that specific story if it wasn’t linked.

Which is, of course, ridiculous. Those news sites are almost certainly gaining visitors from those links, not losing them.
I misread that as "(black water) tank" and got worried.
Small increments add up. Sure, its not 100x faster booting. its 100x less spent in one fragment of overall boot time. Do another 20, and you've made a LOT of difference.
>There's a direct line between her, the court attorney, the owner of the hotel, and Keri Newell.

So the _direction_ connection between the individuals is:

1) The judge was a lawyer before becoming judge, and elected to office.

2) The mayor missed a meeting.

3_ Keri Newell met with the county commissioners.
“Is never okay” is not a rational argument in any philosophical or legal framework. You are projecting theoretically pure ideas into the real world where they don’t exist in any pure form.

Ukraine was Soviet Socialist for most of the 20th century, so any positive democratic movement is an improvement. In 2014, the people overturned a highly Russia-aligned and corrupt government (for which Russia invaded Crimea and fomented a rebellion in the Donbas). Zelenskyy was elected on a populist anti-corruption platform (again, further movement towards democracy).

The party bans you mention happened within a month after Moscow invaded Ukraine with eyes on the capital. And every single banned party was Socialist-leaning + most likely closer aligned with Russia than Ukraine. Again, not exactly a huge regression when it comes to democracy. The sad fact is that Ukraine has never been highly democratic. The post-2014 trend is towards more individual freedom and less government corruption (as far as I can tell, not speaking the local language).

Your standards are a great example of “perfect should not be enemy of the good”, much like the original US Articles of Confederation, which only lasted a few years.
In Texas there was the option to be on a plan that exposes you to spot pricing. The last time there was that cold snap there was some kerfuffle about it, and I think they banned it.
They banned consumer plans that bill at wholesale rates in 2021 after the last time spikes caused massive power bills.

> When the FreeBSD kernel boots in Firecracker (1 CPU, 128 MB RAM), it now spends 7% of its time running a bubblesort on its SYSINITs.

It’s a 100x speed increase on 7% of the boot time, so it should be approximately a 7% decrease in boot time.

YouTube's recommendation algorithm is just optimized to make money. For some reason it's figured out left-leaning content makes more money. I would love to know the reasons behind that
The mergesort is roughly 100x faster than the bubblesort was. I made no claim in that tweet about the overall speedup.

(But since you mention it, when I started working on speeding up the boot process, the kernel took about 10 seconds to boot, so I have a kernel booting about 400x faster now than I did a few years ago.)
Instead of trying some solution from across the pond, TX could do what virtually everyone else does and that's connect to their grid to the rest of the US.
Back in the old regulated days, the power company would just plan to have enough power for hot days. They would keep around a few old inefficient plants and only run them a few days a year. They might get the TV news to ask people to turn up their thermostats, but that was it. If there wasn’t enough power, somebody would get fired.
welcome to amdahl's law
If you don't have surge pricing you have shortages. The only reason for the surge is supply doesn't meet demand.

If you keep the price the same, people will buy until there's none left. And then you are in worse shape than if you had the surge pricing.

With surge pricing people will switch on extra (expensive) supply because it's worth it, or they'll sit in the dark to avoid having to pay a high bill.

You can do what you say: Encourage people to cut usage, and in fact Texas did that a while, and everyone with such an electricity contract enjoyed the cheaper prices, until there was a surge and they were shut off.

People decided that that was worse and now such contracts in residencies are rare.

All your suggestions have been tried and found to be worse at the end. Surge pricing is the best option available. Mostly because it leads to more supply, and that's the ultimate solution.
I was merely just trying to do a calculation to put it in context. A lot of people in the comments are talking about how unfair it has gotten for consumers for this to happen. I am just trying to state that it is not as much of a burden if its put in terms of the actual potential monetary harm. When most people see "prices soar 6000 percent" most people assume that this doesnt just mean a $15 total icnrease.

There is an obvious trade-off in cost here. If a state wanted to it could force its citizens to pay twice as much for its power and build twice as much power plants. Or force people to build solar panels on all new construction etc. People may ultimately say this is more of a burden for the typical user even if it would avoid the 2 times a year where everything goes wrong.
Sorry to hear that, my name certainly has a meaning and reason.
My family in Texas has told me that some electricity cooperatives have been disincentivizing solar by charging different rates to customers with solar or charging fees when customers with solar produce excess power.
Why does any sorting anywhere use bubble sort at all? Aren't there sorts out there that are strictly better?
For the most part, we have solved this problem with electricity. The wholesale price of electricity varies contiually due to market/grid conditions. However, regular consumers do not purchase electricy wholesale. Instead, they buy electricity at a fixed rate from an energy provider, which then buys at the spot price [0]. The energy provider charges a premium (on average) for the service, and utilizes various financial instruments to mitigate their downside risk.

Some markets allow energy providers to pass the spot price onto their constumers. This allows them to offer, on average, lower prices; but exposes the customers to the downside risk of high spot prices. Of course, those customers sign up for the low price, and do not purchase any of the financial instruments that make the fixed priced system viable. When spot prices get too high, they have a serious problem, that can infect the entire market if too many people are on such a plan and cannot pay.

Texas ran into this problem a few years back. I would like to think they outlawed spot pricing for normal customers because of it, but I'm not sure. Regardless, I would assume that most people learned their lesson and are now on fixed priced contracts.

Major electricity users also tend to be larger industrial or commercial entities, who can handle spot prices better than consumers. In addition to being able to purchase the same financial instruments energy provides do. These users are also in a position to significantly reduce electricity usage when given the proper market incentive, allowing both them and the grid the ability to realize the theoretical benefit of spot prices.

[0] I am not familiar with every market. There may be somewhere where people buy directly from the utility, although the overall story is mostly the same.
Your statement sounds like you're joking, but either way, it means someone died. It'll be back to normal after 2 days, assuming the story stays on the front page for 2 days.

EDIT: Seems like it got taken down now.
Is it though? Lots of what data centers do is around organizing people so that they have jobs that get them housing and food and so on

At least for the rich westerners, that data center is quite essential for the household electricity consumption
EDIT: I misread—please disregard the below comment.

3.5% decrease.

A 100% increase in speed is a 50% reduction in time.

E.g., traveling 60km at 30km/h takes two hours, but at 60km/h takes one hour.

Stream Processing Engines and Streaming Databases: Design, Use Cases and Future
This text helps to understand the nuanced interplay between stream processing engines, streaming databases, and their batch counterparts.
Going to have to define “waste heat” in this context, the crowd that needs to read this currently believes “energy use I don't like is generating waste”
yes but some of this 2% require massive amount of potable wáter as cooling and this (zero-carbon initiative) only account of direct electricity use not indirect use
Also, what about consideration for how much other energy is displayed by automated processes doing things in the cloud? Without the datacenter and the cloud applications, how much carbon would be created through more manual processes?
Wow that's a lot considering our lighting has gotten 10x more efficient in the last 2 decades. A 100W bulb can now be covered by a 10W LED. And really nobody uses incandescent bulbs anymore.
It can be argued that any types like those described by you are wrongly designed.

For a self-referential type like a graph, either a value of the graph is completely stored in a contiguous region of memory, including all nodes, when the self-references should not be pointers, but offsets from the start of the region, and a graph value can be moved or copied anywhere without problems, or else a graph value consists only of a list of pointers, which point to node contents without pointers, which are scattered through the memory. In the second case, a graph value, i.e. the list of pointers, can also be copied or moved anywhere in the memory without any problems, like you would do with any single pointer.

Mixing pointers with data makes sense only for objects with embedded pointers whose purpose is to allow them to be inserted in linked links or trees, where such objects will never be copied or moved, but only created and destroyed.
Where do they get the data from?
I bought it 3 years ago when rates were low. Used an agent. Put < 20% down. I feel bad for people buying now, and am thankful I was able to buy when I did.
Because bubble sort is often faster for small sorts and it’s easy to write. This is the kernel, there’s no libc you have to write the sort algo yourself.

The CMB is everywhere, but it was emitted by the initial formation of neutral hydrogen (from plasma) in the early universe. When people talk about the CMB being far away they're really talking about the last scattering surface, which is that early plasma as seen 13+ billion years later.

Disk full is not a “corner case”. It should be one of the first test cases a filesystem test suite should have, and that test should always pass in every configuration.

The fact that total data loss happened regularly on full volumes many years after a “stable” release means BTRFS is either fundamentally flawed in design or incompetently implemented. I have no idea how it was accepted into mainline Linux.

The fact that a certain large NAS vendor used BTRFS by default (without documentation at the time of purchase) has cost my org and others lots of downtime and money.
Why not sort this in a precompile step and not sort the static list every boot?
This article's misleading. It's talking about spot price contracts. This is the price electric providers themselves pay and certain large businesses which opt into the potentially extreme volatility to achieve lower overall pricing. If there are any 'normal' consumers on spot-contracts, it's exceptionally rare. Just about everybody's on fixed price contracts, which have been trending downward in cost.

The other extreme side of this coin that you will sometimes see is spot-prices going negative. Needless to say, customers don't receive a check in the mail as their bill during those times, anymore than they suddenly get a 5 figure bill in these sort of times.
