It can be a bit mysterious until you look at how it works.

Most CPUs provide memory permissions with granularity of pages, which are usually 4 KB in size. The OS manages these by modifying a "page table" which the CPU uses. Changing the page table is not free, so the userland allocator (malloc/free) will request large blocks of memory from the OS (with mmap) (or sbrk, if you're a dinosaur) and then divide them up into smaller blocks for your program. They typically remain accessible until the entire original block is freed.

If you allocate a large enough block of memory, it will typically just be backed by one region of pages made with mmap. Then, when you free it, the allocator will munmap it. You can test this out by allocating a large block of memory, freeing it, and then dereferencing it.

Your system might do this for 1 MiB allocations, for example... change the allocation size and see whether it still crashes.

#include <stdio.h>
#include <stdlib.h>
int main(int argc, char **argv) {
volatile int *ptr = malloc(1024 * 1024);
puts("*ptr = 1");
*ptr = 1;
free(ptr);
puts("*ptr = 2");
*ptr = 2;
}

Most crimes committed by US citizens in foreign countries are in the context of their military service: War crimes. And instead of being incarcerated for those, they just complete their tour of duty and go home. With any luck there's some public outcry about their crimes, but often not even that. The US is also not party to the Rome statute (https://en.wikipedia.org/wiki/Rome_Statute), and has even threatened to personally target International Criminal Court employees if they try to prosecute US citizens.

... but I suppose you're right about more mundane, non-government-sanctioned crimes.

I apologize for my lack of clarity. I was implying that since Google owns 90% of the search market, that they have the ability to steer people toward paid search without market pressure. To steer people in that direction, one approach is to water-down search results to create frustration in the consumer, and then offer to provide paid, higher quality search results as a solution to that frustration.
One thing I don't fully understand is how KV stores like this fit into the overall architecture of an app. Is Ditto supposed to completely replace SQL or is there some Ditto DB <-> SQL DB syncing mechanism happening?
The EU insisting on all phones standardizing on the USB connector is evidence of just the opposite and shows the cluelessness and shortsightness of the EU.

You will still have phones that come with “standard USB C” cables where some support different power delivery, data speeds (or not support data transfer at all), very few will support video over USB C (which is standardized), etc.

So still when the Android user with the cheap power only USB C cord moves over to the hypothetical iPhone 15 with USB C, they will still have to throw away their USB C cable that potentially doesn’t support high speed data or video over USB C. Both supported by todays iPads with USB C.

If the same mandate had gone through when it was first proposed, we would have been stuck with micro USB.

I don't doubt that Amazon fixes prices higher than they would otherwise be, but I still find that Amazon is frequently absurdly inexpensive. I avoid Amazon when I can, because I do not like the way they treat their employees and I wouldn't trust anything electronic or edible from them, but any other option is likely to take longer and cost more.

I'd love to see Amazon face serious scrutiny, but I suspect it would make prices go up, not down.
Lol.. gotta love when they propose acts before even understanding technology. Things like this need to be collectively written by some of the best privacy advocates. Not a bunch of interns that have no clue how technology works.

I know for a fact that publishers will now vet authors as well as manuscripts. A nice-looking and personable author, preferably with a well-oiled presence on social networks, has a much higher chance of getting published than the rest of the pack; that's because publishers now "sell" the author as much as the book.

seems like something that could be handled at the memory/controller level instead of wasting CPU cycles writing 0's.
That the two splashy examples are hot people in their underwear is pretty telling for what one major use of this will be. Makes me feel weird. I find takes on deepfakes fraying shared epistemology alarmist, people will continue to believe whatever they want to believe and falsifying evidence is still a crime, but the ability to conjure moving images of whatever human body you want without that person's permission feels bad. DALL-E adding protections against sexual or violent imagery is a short term solution, at best, IMO. Maybe I'm being alarmist, too. Perhaps it won't be as easy as toggling a switch next to your friend's photo to take their clothes off.

This is a classic case of "supersonic is not the answer." Depending on the city pair, this is a ~15h nonstop on a commercial flight today. If an airline started serving your city pair, you would immediately save 9 hours.

Also keep in mind that supersonic won't help beyond the coasts due to noise/overflight rules that would require flights to slow down over the continents anyway.

I think it's pretty naive to think that everyone who didn't agree with "the science" that the government (and pfizer) decided was the "real science" were flat out wrong. Science is about proving hypothesis with experiments, publicly, so that others can independently verify the results. That's not what happened with anything related to covid though. The government said one thing, and declared everything else to be misinformation that wasn't even worthy of a rebuttal. I get that it'd be a fool's errand to respond to every single disagreement, because yeah of course some of then will be ridiculous. But writing off credentialed and respected doctors and scientists because they don't 100% agree with anthony fauci (aka Science itself) seems

And why does no one question motives of pfizer? Didn't they just make an insane amount of money selling vaccines? Didn't they also just (in 2009) get charged with the largest case of medical fraud in history? Remember when people had a healthy distrust of massive pharmaceutical companies that profit off sickness? What happened?

You actually can, there's just a gigantic mountain of evidence showing that you are wrong. So there's not really an argument to be made there.
Slack is not a community forum. If you ask Slack support they will explicitly tell you that and ask you to use Discord or something else. I'm not sure why people are surprised or outraged here.
That makes sense! And as I thought about it, this is an excellent example of where AI can enhance but not replace human decision making. It can make it easier to search through his podcasts, but still require human input to make the correct interpretation.
Personally I've never paid more than $7000 for a car.. but yeah, a cheque, or a transfer. You transfer the ownership at the govt office, and it's done.

Dropping 30k on a car seems a little nuts to me, but I understand different people have different values.
> I'm aware that errors are more likely when the model is less confident of its predictions, but that shouldn't be enough.

Suppose 90% of the errors are in the 10% where the model is least confident. Then you can review just 10% of your content and take a 2% error rate down to 0.2% error rate.

In past they took much space in comments and messages. Now most sites have gotten smarter and automatically shorten a long URL when presenting it. For the first part, depending on site, a deterministic shortener could be possible. For example "example.com/blog/2022/09/22/first-article-of-the-day.html" can be "example.com/s/b22092201". Remember read someone utilizing something like this but cannot find the article.
Always good to see links to direct text of bills.

Reading the tea leaves a bit, Speaker Pelosi seems dead set against it and I dont think will allow it to be moved as is. she has publicly stated that "states must be allowed to address rapid changes in technology", IE, the bill preempts to many state privacy regulations, esp in California. But as a rule my default assumption for the "real reason" why Pelosi is against something is because she thinks it will harm chance of caucus holding majority in house.

Skeptical as I am of her motives / methods, I'm inclined to agree with her in this case. Act should be a floor not a ceiling.

The best thing about cross-linking between Git and an issue tracker is that when you have multiple commits for one ticket (very common), they can all link back to one ticket. Having the extra context from discussion is useful, but obviously that can be summarised in the commit message. So being able to instantly get a list of commits that link to the one ticket is the really invaluable feature that I don’t know of any good way of doing another way.

For kids the vaccine almost certainly is more harmful than Covid. That’s why many countries don’t push kids to get vaccinated.

As for the “horse dewormer”… don’t you find it at all curious why none of the “experts” ever suggested any kind of treatments for Covid beyond vaccines and paxlovid. No “eat healthy, take your vitamins, exercise, get fresh air”. Nope. Just hunker down in your home and wait for salvation. Any attempt to find other treatments for Covid were immediately shot down and roundly mocked.

Weird, eh? Like what kind of assholes shoot down doctors and basically cancel them trying to find treatments for Covid? Who does that? In what world is that normal?

Even more odd is none of them bat an eye when they push some omicron specific booster that was only tested on like 8 mice before being deemed legit.
On Mac, malloc has several options to help find such bugs. If you set MallocScribble=1 in the environment, it fills blocks with 0xaa on alloc and 0x55 on free.

On Linux, running `env MALLOC_PERTURB_=43605 myprogram` will do the same.
If passenger density was comparable to a typical airliner, an intercontinental E2E flight should be roughly comparable to a subsonic flight. The supersonic flight would be substantially worse. Rockets have the advantage that they very rapidly get out of the dense part of the atmosphere.

In reality a Starship flight would probably sell few very expensive seats instead; just like Boom's aircraft only has 50 seats. Which would make it worse than subsonic flights in terms of fuel used, but still competitive with supersonic.
That's not really so surprising though. Any brand that already has a system would be penalising existing customers by changing, we're not talking usb cables here.

For me, I'm totally fine with the house being cold and in the low 60s during the winter and just using sweatshirts and space heaters as necessary.

However, some folks (especially females) don't like the ambient air being that cold because their fingers start to hurt. Can't blame people for not wanting to wear mittens at home.

EDIT reply to: >(note that some people regard the use of "females" as a noun to be a red flag)

Thank you for the heads up but I'm surprised "females" has become controversial. I did a cursory google check with a mainstream respectable outlet like NYTimes and they use "females" the same way I did. When did the norms change?

I'm actively developing this, here's my list of next things:

* make the tool author new page-object-model files
* workflow to append to page-object-model files
* support nested page-object-models better (scope selector)
* make playwright selectors work both ways (only work one-way right now, generating, not executing)
* page-object-model patterns flexibility - embellish recorder rules with method parameters
* add an animated gif to the top of the readme showing usage
* clean up ui
* margins/alignment
* add toggle to show/hide
I'd ad Youtube to that list. I turned off personalized ads and oh boy a whole lot of sexualized Flow Ads and other weird stuff came up, including ads for Newsmaxx. Absolutely gross that those are the apparent defaults.

For anxiety “getting yourself out there” can literally be the entire issue in the case of agoraphobia, and the reason you see a doctor.

I don’t see this law as trivializing the treatment of anxiety, I’ve seen it be treated across multiple patients over a course of a quarter century and I would say probably “get yourself out there” was the most common treatment option used across many visits because being housebound tends to make the anxiety issues people are worried about enough to go to the doctor about worse.

I’ve also generally seen practices like children and dependant adults with autism (who usually have comorbid anxiety) getting guided through all manner of public places with social workers and guided to do various tasks and a huge objective of such efforts is to soothe any anxiety issues in such exchanges. I’ve seen quite a lot of this actually at significant public expense.

In any case if you read between the lines this story essentially means people with anxiety can go to the museum for free and that’s probably a positive development since we want to remove any potential barriers to the anxious getting out of the house (poverty is another anxiety comorbidity).
Mold is caused by not handing water vapor well, you can have a building that is not climate controlled that has no issues with mold. In fact, mold is usually caused by preventing the free-flow of water vapor while conditioning the house.

https://www.youtube.com/watch?v=IEMZk5Kjqkw

Freezing pipes is another issue, but that can be remedied by conditioning to 40 or 50 degrees (freedom degrees™) but I suppose you could build a building with anti-freeze dedicated to the piping itself.
I really should floss more, but then again after seeing what happens to the body and mind after age 88 or so - not sure I really want to live that long anyways.

The way this EU ruling is setup, they want your Android not only ship with other stores, but allow sales with exclusively those stores as well.

Just like the case with Chinese phones now - I have bunch of people in my family angry because they bought Huawei and they now can't use their banking apps because it's an incompatible build of Android that requires publishing in a Huawei AppStore to work.

That's worse. That's strictly worse for everyone, even the OEMs will lose their market to Apple by driving their ecosystem into the ground... again. Samsungs, Nokias, ASUS, etc. did this tragedy of the commons failure repeatedly and reliably.
I think you underestimate how much separation there sometimes is on large teams with the people who run/build the website, vs the marketers who are moving fast. I've seen terrible devs who will claim it takes DAYS to add a simple redirect of dog.com/X to your long marketing url (cutting out services like this), but the marketing team can't wait that long so services like this are much more async in many contexts, too.
Welcome news, for sure. It seems that Iranians are fierce people who are not afraid of protesting their government. Why do protests usually stall, though? Is it the virulence of the repression machine?

>Especially common is for national security to override free speech in the minds of government officials. They can easily convince themselves that they need to suppress certain viewpoints in order to save many lives. It just coincidentally also saves their own jobs.
