This looks excellent, but I was hoping for something other than Bluetooth.

I have sworn by Logitech wireless accessories for years because of their integrated wireless which presents to the OS as a regular USB device driver, so I can use the accessories in BIOS, during OS installations, etc without any hassle.

I also like the Logitech USB dongles because I find the Windows Bluetooth keyboard support to be very much a second class citizen, with slow performance and the keyboad noticeably lags both randomly and when the system is under load, unlike a USB device.

This got me wondering if there was some solution for this, such as having a Bluetooth keyboard communicate with another piece of hardware that replayed the inputs as USB. Or perhaps Windows has upped their game in the couple of years since I last tried a Bluetooth keyboard?

I know on Mac it just works (tm) but sadly I cannot escape Windows at work at the moment.
Let's say you have two students of the exact same baseline intelligence. Student A goes to a rich school district and scores well on the SAT. Student B goes to a poor school district and schools poorly on the SAT. That's a problem of the school districts, not of the SAT. Student A is objectively stronger student, and it does no one any favors to try to obscure this.
That explains why this is such a sore subject here. Because if you believe children cannot consent then it would be unconscionable to mutilate them.
It's not an "issue" its the design. GitLab is a web app and not a document so there is no chance they will rewrite the whole thing to support not running scripts.
Okay, that is helpful context. The first portable computer I actually owned was a first-gen Macbook in 2006; these earlier machines I used only briefly or observed from afar, so I don't have nearly as much of a picture of how the timeline of them fit together.

Though of course, it makes sense despite Thinkpads existing in one form or another since 1991, they've also evolved a lot over three decades.
So the typical Tesla driver has an above-than-average income ?
Thanks, captain obvious :)
This is not saying the SAT is good. It is saying they don't have something better.

A lot of people are misinterpreting this.

The zeal of reaction to the problems with the framework left everyone without any framework. A very common failure mode that exacerbate the division in "culture wars".
>TikTok is no different to Facebook (Meta)

Tik Tok exists as a corporation for people to "do business in China" AKA be paid vast sums of money for knowledge and skills that would be treason or whatever to otherwise transfer.

At least Facebook people keep up appearances -- pretend to be a capitalist, then shun any regulations or taxes that differentiate capitalism from oligarchy.

(And Federal Trade Commission is a joke, it's a known thing they can often do one test case when a behavior is being done in parallel across industry by many actors.)
It's complicated, memory accesses can really block for relatively long periods of time.

Consider that regular memory access via cache takes around 1 nanosecond.

If the data is not in top-level cache, then we're looking at roughly 10 nanoseconds access latency.

If the data is not in cache at all, we are looking into 50-150 nanoseconds access latency.

If the data is in memory, but that memory is attached to another CPU socket, it's even more latency.

Finally, if the data access is via atomic instruction and there are many other CPUs accessing the same memory location, then the latency can be as high as 3000 nanoseconds.

It's not very hard to find NVMe attached storage that has latencies of tens of microseconds, which is not very far off memory access speeds.
What would happen next is that the attacker would succeed in getting his certificate for mail.google.com signed by the CA (remember, there are certificate authorities including Let's Encrypt that sign certificates based on DNS responses alone, but selectively spoofing the A record for the HTTP server would also work).

Presumably the CA would have to have published an entry to the CT log for this certificate. This would allow browsers to verify that the certificate generated by the attacker can be trusted and therefore it could be used by the attacker to perform a man-in-the-middle attack on the Gmail interface against any user in the entire world, without anyone noticing it during the attack.

Some time after the attack has already occurred, Google or someone else would presumably notice that the certificate wasn't actually created by Google, even though everything was correctly published in the CT logs like it was expected for any other normal certificate (I'm being very generous here, multiple companies don't even notice their domains are about to expire until it's too late, including Microsoft).

At this point, it would be expected for browser vendors like Mozilla and Google to distrust this CA because they would assume the CA generated a certificate for a Google domain fraudulently. However, the CA wasn't actually the perpetrator of the attack but it also couldn't prove that it wasn't, and since the browsers don't trust them anymore, the innocent company would be ruined and all their employees would be fired and become miserable.

Meanwhile, hundreds of millions or possibly billions of devices (like Android smartphones) who don't update their system software for months or years (or even never) would still have the now-bankrupt CA in their certificate root stores for a very long time (remember, not all certificate root stores are managed by browsers, some are installed at the OS level), so the attacker could still keep attacking these devices, almost indefinitely, without any issue (especially if he repeats the attack, which he can do indefinitely, ruining many CAs until he somehow got caught).

This is all assuming we're talking about a certificate for an HTTPS server, which is the best case scenario.

If we're talking about a certificate for an SMTP server or a DNS server then the problem is even worse, not in this exact scenario, but in the scenario where one of the many certificate authorities behaves maliciously and generates a fraudulent certificate itself (signing it) but doesn't publish an entry to a CT log, so the attack would never be noticed because SMTP servers and DNS servers don't check SCTs.
You can use userspace Coroutines/fibers implementations to wire in async io_uring into existing synchronous code and maintain the facade of the code still being synchronous

How easy/feasible this is depends on the language.

In C++, Rust, Zig, Java (Loom fibers), and Kotlin I know for a fact it's doable

Other languages I'm not sure what the experience is like

Wardley seems to have a narrow perspective on things, then. Lots of large companies build their own roads and power plants. Hell, I put solar panels on my roof.

In fact, there are very few companies over a certain size that haven't built a road. This kind of overhead is generally expected once you have scale, because the alternatives are far more expensive. Datacenters are similar.

There has been enough evidence to ban TikTok for years. I can't think of any reason it hasn't happened yet other than politics.

It's a little weird that you're trying to tell someone that SAT test prep doesn't work, when test prep absolutely did work for them.

It worked for me, too, though I already had a high score, and wanted to see if I could get it even higher. (It worked; I did.)

That's great that you managed to develop SAT-ready vocabulary and math techniques on your own before taking the test. Many, many people don't, and test prep can help fill that gap, not only in their knowledge, but in strategies that work well for the test itself. And that last bit was probably what helped most for me: I, too, had a solid vocabulary (I read a lot growing up), and I never had trouble acing my math classes. But understanding how the test itself worked was helpful too, and netted me a nearly-perfect score.

It's pretty irrefutable that this can work; not sure why this is the hill you've decided to die on.
> They will not hesitate to pull the plug in an effort to harvest your organs while they're still "fresh"

On the contrary, it seems like they'll keep you on life support after brain death to ensure your organs are still fresh.

> that decision should be made by my family and not the vultures at the hospital.

I mean, sure. In most places it's your next of kin that decide.
You do know that the hospital doesn't get paid for organs donated, right? I have no idea what incentives you think they have to kill you.
Sounds like you have a fundamental misunderstanding of the goals of advertisers versus the goals of state governments.
> They prioritize profit and censorship over engaging grass roots content.

you seriously think tiktok is prioritizing grass roots content and not siphoning off massive amounts of data for profit?
I am also accusing Facebook, Apple, and Google of the same thing. Can we add them to this inquiry please?
I'm sure they will use our data more responsible than a semi-hostile foreign government...
I've seen similar comments about Idiocracy.

It's more likely what those who can don't use TikTok. Or smartphones. Or computers. Ever.
A lot of these aren't roguelikes.
But that would cover him in grass, perhaps. The quartering I mean.
Just ask anyone in academia? It barely counts as an open secret. Most admission forms (for the Cali and other state schools/private schools) would ask you explicitly if you have any relatives working for the school and their specific title and role.

Display likely be remotable, but higher frequency & the vector extensions would be helpful.
The results haven't changed much so I'm not sure what you expect. Perhaps you're used to Tiobe which is very inaccurate imho. The only surprise here for me is Dart has moved up significantly.
Why does it seem so odd to you that learning how the test works, and learning about strategies that work for the specific test, can increase your score? It seems obvious that this would be the case, and it's pretty clear that this actually has helped many people (myself included) get a better score on subsequent attempts.
Very nice, thank you @meesterdude!

If Putin uses nukes on Ukraine, do you really think Ukraine, which has access to lots of nuclear material, wouldn't retaliate with a dirty bomb on Red Square and other locations?

Where do you think that would end?

Such a strategic situation would be incredibly unstable. If no retaliation comes, the madman will think he can use the same gambit to take the Baltics and other areas. He's been at this since Chechnya. There's no way he'll stop his aggression and violence unless someone stops him.

The only way to stop this is to effectively deter him from using them in the first place. And the only deterence is to credibly threaten immediate nuclear retaliation.
This apparently just came out, was thinking they had this out for some time.
Machine Learning, Occam’s Razor, and Fundamental Physics
This is the most confused comment I've ever read. What are you even talking about? What metric did you think that a company whose goal is to make money was going to optimize on? What metric do you think TikTok is optimizing on (hint: it's not "grassroots content" whatever that means)
This must be the most pragmatic "to-the-point" landing page I have ever seen. Logo, CTA button, value prop, sample code that explains the whole thing in a simple way, pricing, contact-us _à la_ eat your own dog food. Amazing.
Why the downvotes? I'm just paraphrasing what the GP said because the parent misunderstood.
Dart as well. It's nice to see the underdogs move up.
This looks pretty cool! From the docs it sounds like one can pick the underlying cloud provider and region, is that true?

The only person I've met in real life who did email stuff for the GOP was literally in a cult. He showed me their compound. I had just begun to forget about them, then Netflix did a documentary about them, they were called "The Family".

https://en.wikipedia.org/wiki/The_Family_(miniseries)

I remember them complaining their 501c3s get audited disproportionately when... surprise surprise... GOP leaning nonprofits tend to not pay taxes as often.

Anyways, maybe the emails went exactly where they belong.

(And I'm saying that as someone who's very, VERY happy that Duckduckgo is forking huge chunks of Google's revenue away from them... no love for GOOG and there has not been for a long time, but to be fair... Gmail did have a good UI. I hope they take it out of beta eventually.)

Well the quality seems to have ramped up considerably.
TikTok exploded precisely because they let regular people create content, and then showed it to other regular people. Ofcourse they are making cash. FB basically stopped showing regular people's content, and constrained it to accounts/topics that were attractive to advertisers. There's a huge difference. They got caught with their pants down.
How much of all companies build their own roads?

Personally I'm reserving judgement until this is confirmed by other news sources, because the details seem sparse, the motives unclear, and I don't hold Forbes in a high regard journalistically (though this is at least a staff writer, and not a contributor, so presumably there's more editorial oversight). My intuition is that there's a 55% chance this story is true, and a 45% chance it's incorrect or overstated.
Where do the apes come in?
Man, I could've written this post a few years ago. I want to commend you for being so brave to ask for help, that's incredibly hard as a step one.

Here's my advice from my personal struggles, maybe it resonates:
You need a North Star, something that helps drive the decisions you make. I found my North Star by realizing that similar to how I had my father's tendencies, my kid would have mine.

I didn't want my impression on my kid to be my depression and lack of enjoyment for my life, which meant getting up, exercising, being compassionate, and doing what I loved.

Waking up every day saying "Let's be a better father for little HakuG" is all I needed. I don't even have a kid yet, but it still drives a large majority of my decisions.
> And also, does it imply the existence of non-blocking memory

Yes actually! If you know your going to need a block of memory before you actually need it, you can put in a request to the memory controller before you need it, then proceed to do some other work and check back in when your ready for the data or when the memory controller signals you it's done. It's just that this kind of thing is usually the scope of compiler optimizations or hyper optimized software like Varnish cache rather than something your average web developer thinks about. It's again conceptually the same as an async network request, but you bother with one while considering the other just "a cost" because of the different timescales.
If video game experience is of any relevance, I noticed that taking shots on the move with no time to react yields better results than consciously aiming.

There are times where I have time to line up my shot and track the enemy in my sights and yet in some cases I miss all my shots (I actually end up being out of sync with the enemy’s lateral moves, essentially lagging behind).

On the other hand, there are times where an enemy surprises me and I move my mouse in a sudden motion, shooting while it’s still moving - I manage to land the vast majority of those shots (sometimes shooting twice in panic, but the first one turns out to be a hit - this is on PC so no aim assist as far as I know).

Not that I would like to “prove” this hypothesis in actual combat, but I wonder if taking shots “by feel” is actually better than doing so carefully and consciously.
I’m imaging a future where people are using Tor to access the hot new TikToks.
Sounds like you (also) have a fundamental misunderstanding of the goals of advertisers versus the goals of state governments.
You should do a write up of item 2.
oof. Own goal.
How likely is that situation vs. being considered brain dead and having all life-supporting treatment halted? It seems like you're more likely to survive if they try to harvest your organs than if they unplug you and leave the room.
TikTok lets regular people create content, and then shows it to other regular people. As basic as that sounds, FB/Google have all sorts of manipulation behind the scenes that stops that from occurring at the same scale. And so TikTok exploded because people could actually communicate in an organic way through video media.
Isn't GitHub actions free for only public repositories?

Can we all please stick to the topic of the post here? That Tiktok is a threat to the society especially when a foreign company with questionable ethical and moral practices is in charge of American teen data.

If you want to discuss how western companies also collect the data, then go make a different post and discuss there? The false equivalence by comparing Tiktok to other tech companies ruins any discussions we could have here.

Yeah afaik they also had some issues with MMAL using some hardcoded address jumping that while it did work on 64 it would on occasion go outside the new virtual address range and crash, which made the Pi Camera and the GPU very unreliable. I suppose by now Broadcom's already fixed that given that there are actual 64 bit builds on the official Raspberry site again.

While there's a lot left to fix I'm sure that part of the slowdown is also just physics. Even if it's native, there's an extra layer of abstraction to process, you need to fetch twice the address bytes, and write twice the address bytes. Makes sense it's roughly a 2x slowdown since it's doing 2x the data shuffling (especially since it's in single threaded performance).

Or it's far more complicated than that and it's just a coincidence that the numbers align...
TikTor considered harmful (2028)
I just want to add to your explanation, that even in the absence of hard paging from disk, you can have soft page faults where the kernel modifies the page table entries or assigns a memory page, or copies a copy on write page, etc.

In addition to the cache misses you mention there's also TLB misses.

Memory is not actually random access, locality matters a lot. SSDs reads, on the other hand, are much closer to random access, but much more expensive.
With 96 month auto loan terms they can now cast a very wide net and access a lot of otherwise very under-qualified buyers. I think 84 months is now the average auto loan duration.
For those going, "well, what is the Chinese government going to do, compared to Facebook?" Or saying, well, Facebook does the same thing right?

Well... potentially kidnap you and bring you to China, if you don't comply. They supposedly "convinced" 230,000 Chinese nationals from April 2021 to July 2022 to "voluntarily" return to China to face criminal charges, complete with over 54 "international police stations" and a new law, going into effect this December, claiming extraterritorial authority over their "citizens" for certain crimes.

This, along with other incidents, show that China is more than willing to harass people outside their country, at a minimum.

Yes, whether a write blocks is really about whether the application can do anything else while the write is processed; whether the application is told the write is done when it lands in a cache or when it is actually on stable storage is a separate question.
TikTok bad at culling US election misinformation ads
I’m not on call, but when doing interviews I explicitly ask about the on-call setup (if any). The usual setup (for backend engineers) is:

- 1 week in-call every 5 to 6 weeks (depending on how many engineers are available for on call)

- if you get paged, you need to acknowledge within 10-15 min. Sometimes it’s nothing and you can go back to sleep, but sometimes you may need your laptop to fix things. The point is: you don’t know before hand

- it’s paid. In my opinion the money is not worth it

- it’s mandatory. But even if it’s not, if all your teammates are on call and you’re the only one who refuses it, well, that usually creates friction
All that will happen is you get local clones… not a bad thing IMO.
What the “TikTok is just doing what other social media companies are doing” response misses is that US platforms are under the purview of US law and US government.

The US govt’s extensive monitoring and archiving of its own citizens + foreign citizens information is widely known at this point.

This is a source of wide consternation for other foreign governments because the monitoring is a tremendous asset for US domestic and foreign intelligence, defense, and cyber warfare which is of course why China has banned many of these US services.

Meanwhile TikTok has grown like a weed in the US and several times the so called “firewall” supposed to keep the US version of TikTok separate had been demonstrably proven to be effectively non existent.

And considering the scale of election meddling, astroturfing, and psy ops that take place on US platforms - that both private industry and govt have failed to contain - the US intelligence community and govt likely well understands the threat of their unofficial, global arch rival owning the fastest growing new social media platform.

I would love to know what the intelligence community is doing behind closed doors at this point but they must have balanced TikTok as an asset vs liability given the obvious threat it poses to the US’ near ubiquitous control of global social media.
Not a game to play when it comes to asymmetric business and trade relationships. You’re “better” until you’re irrelevant and have no industry left.
