USB4 Version 2.0 to offer up to 80 Gbps data transfer
"Once again following USB tradition"They certainly are following USB tradition with that brain-dead name.

Samsung is throttling the performance of over 10,000 apps
If you look beyond the obvious "they're cheating" response, this opens up some fascinating questions.*Why* are they doing this? The answer is a lot less obvious than you'd think. Benchmarking apps will use as much CPU as they can get their hands on, and so will obviously be affected by being on the list, but most of those 10,000 apps should not be. After all, MS Office, Netflix, Tiktok - generally speaking, none of them require full CPU utilization. They're just not doing that much work.So why are they listed? DVFS should be enough to manage the CPU for all these apps! And even though the DVFS implementation on various Androids has sometimes been poor, it should still be better than the ridiculously blunt instrument this throttle is.In fact, this throttle is likely bad for battery life in most cases. Race-to-idle is demonstrably the best way to go, in almost all cases. The only exception would be if the CPU were set to run so far off the optimal voltage that running at full speed was dramatically more expensive than executing the same number of cycles at lower speeds, which shouldn't be the case, except possibly for a couple of the recent Qualcomm chips (and I'm skeptical even for those). Even then the DVFS implementation would have to be totally broken.The two major obvious exceptions to this general rule are benchmarks and graphics-intensive games. On PCs/Macs, you'd also include video editing and a few other things, but these are phones, so that's mostly not a thing. And those aren't going to be on the throttle list or the phone will show up as slow when tested. So... what's the throttle for? Can they have broken DVFS that badly?This is really really weird.Edited to add: I could imagine using this kind of tool to deal with very badly written apps that suck up all available CPU for no reason - say, an app with a busy idle loop. But there can't be that many of those.

How to copy text from locked PDFs in macOS
Worst article of the year?Most of the time you can just "print to pdf" the locked PDF, producing an unlocked PDF. Then copy from that.

Tested: Thermal throttling and performance in the eight-core 2019 MacBook Pro
@AI, thank you, that was very useful, and quicker than I expected.@Lkrupp, maybe some trolls are doing that, but it's still true that the current design is a poor choice if you're optimizing for performance. (It's a different story if you're optimizing for weight, battery life, etc.) It's also true that in the last couple of years, for the first time ever, other companies have been putting up legitimate contenders against Apple for the combined weight-batterylife-performance-style crown. In my opinion, Apple hasn't done too well on that front recently, though the latest macbook helps a lot. If I could get MacOS on another brand's hardware, I would seriously consider it, and I never felt that way previously. Of course I still won't, because Windows.

How we ended up with the 'Pregnant Man' Emoji
addison huy said:Males can’t get pregnant so I don’t know why such an emoji would exist. It seems pointless. If your sex is male then you can’t have children this can’t be pregnant. All these gender and sex methods that are used to describe people now are so confusing. I remember when non of this really existed before and there were only men and women.Dear lazy person:If you can't be bothered to read what other people have written, why should we read what you wrote?This has been extensively covered here already. You are, for certain meanings of the word "male" which are used by a large portion of the population (though not, apparently, you), simply wrong.Lots of people remember when blacks had to sit in the back of the bus. And put up with getting killed for looking at whites the wrong way. Your memory of a simpler time doesn't make that time better, or more just. Also, what you remember amounts to a conspiracy of silence. These things existed. They were just concealed.

Russia tried to hijack some of Apple's internet traffic for 12 hours
dewme said:
Thank you for providing a voice of reason on the topic.JustSomeGuy1 said:Less ignorance, more facts.
This would have zero impact on the situation described in the article. Had they already done so, nothing would have changed. Rostelecom could still have announced Apple's route(s) - which is an entire /8!!! - and everything would have played out exactly the same way.DAalseth said:Apple needs to sever all ties with Russia. Cut them off cold to updates, services, iCloud, AppleMusic, everything. Flip the switch without warning. You live in Russia your device is bricked and you are SOL. I know that Apple keeps talking about trying to protect their customers. It's too late for that. Until the general populace starts feeling the pain from Putin's war they won't put an end to it. Remember, that's what brought down the Tzar. The people get fed up with paying in blood and treasure for the Tzar's adventure in WWI. It's time for another revolution and Apple needs to step up and do their part.
No, to both questions. This has nothing to do with attacks on cloud services. It's fundamental to all traffic on the internet. And the problem is exactly the multiple possible connections, in that the lack of a central authority for the net means there's no single source of truth for who is allowed to announce which routes. There has been an answer to that problem for over two decades, but it's not used everywhere, much to everyone's detriment. See http://irr.net, or google "radb". If the entire world used and enforced registration of routes in a route database like the RADB, this attack could not have any effect outside of Rostelecom's own customers.bobolicious said:... is this a good reminder of the potential vulnerability of (especially large, high value) cloud services with so many potential attack vectors ...?
... is it the opposite of the concept of the internet in terms of communication reliability of multiple web connections ...?
This is extra ignorant. Just stop.9secondkox2 said:Very serious and calculated move by Russia.Also finding vulnerabilities in the routing infrastructure.Russias war isn’t going to stop with Ukraine. That’s a strategic move to gain a massive nuclear power plant while advancing its dominance agenda. They e already threatened their own surrounding countries as well as the USA. And China is right behind with its unprecedented disrespect and threatening of the USA as it seeks to devour one of the most prolific product economies in Taiwan prior to its 2049 buildup goal.Though Apple was vigilant, there is no doubt that some data was stolen. You have to wonder what kind of blackmail is planned for any incriminating info discovered, especially where apple using politicians, media, and big tech folks are concerned.1) This isn't a "vulnerability in the routing infrastructure". It is, unfortunately, a designed-in feature. It will continue to be the case until use of route databases is universally enforced.2) I have a LOT of doubt that any user data was stolen. In fact it's virtually certain that no data was stolen, as all of it was likely encrypted, though they certainly would be able to capture some metadata - for example, who was connecting to Apple services, and when. The scenario you envision is not the problem. It is conceivable that the metadata alone could matter in a specific case involving a high-value target, however. That's a reasonably plausible explanation for the whole event, in fact, though we'll likely never know.3) Off topic, but the notion that Russia invaded Ukraine just to get control of one aging nuclear plant is ludicrous.
Considering everything they did left a very clear trail back to the source and was essentially done in the open makes it hard to get too excited about this. It’s essentially the same as someone giving the post office a change of address form to route your mail to their mailbox, all the while telling you and the rest of the world that they are doing so. Whether it’s amateur hour, cyber heckling, or just being done to create a distraction we’ll never know for sure. So while I’m not overly concerned about this specific incident, we don’t know what their next move might be insofar as they operate in an environment of state sponsored terrorism.You're welcome.I hate to say it, but the next step is obvious: Break the internet. All they'd have to do is start announcing lots of routes they don't own, from critical players like amazon and google.The endgame in that case is also obvious: They would be entirely disconnected from the internet. That's a bad result for everyone, but probably exactly what Putin will be looking for, long-term, so why not take advantage of that to do some really spectacular if short-term damage on the way out? It's like tossing a molotov cocktail over your shoulder as you leave a restaurant.

iPad finally has a Calculator app - Here's everything it can do
Unfortunately, as currently implemented, Math Notes is just a toy. It might be useful at some points for grade school and high school math, but not always. Pretty useless at a college level and later. But I have some hope that it will grow a lot - the groundwork is done! Tacking on a much more capable backend is almost trivial, in that it's a problem that's already been solved multiple times. The front end would still need some work, but I think most if not all the hard problems are solved, or well on their way.At the moment, it understands arbitrary variables, but it's not clear how smart it's going to be about them. It *doesn't* understand subscripted vars - or rather, it does, but it refuses to work with them! It's also not clear how it will handle ambiguity, like, what if you declare n, m, and p, and then declare np? How does it calculate "3np"? That's obviously a user error, so hopefully it will have a smart way to help the user fix it.It has no idea what matrices are, AFAICT. Much more problematic, it doesn't support function declarations.Part of me feels optimistic about this - it could be an AMAZING showcase for useful AI tech supporting a general-purpose tool. But part of me remembers the Mac graphing calc app sitting in the utilities folder for so many years without getting any love.
brianus said:Can anyone with the beta confirm that this supports slideover?Yes, it does. There are a few small display bugs that I've noticed, none significant.
...sort of. You can write a a second-degree poly as y=... and it will offer to graph it for you. Look at the intersections of the X axis and you have your solutions. No actual application of the formula though. And certainly no factoring. It will graph higher-degree polys but it does not support 3-d graphs, or generally any of the cool stuff that's in the graphing calculator on the Mac. I really hope that they will merge the two codebases, or at least borrow a lot.mikethemartian said:Can you write a second order polynomial and have it give you the roots using the quadratic equation?
Variables are better than a stack. The trackpad is useless. ThePencil is great if your handwriting is decent. It's semistupid about bad writing- not terrible, but not good.dewme said:Without having used the new iPad calculator, if they provide a result stack or memory register/buffer save and recall it should be easy enough to solve a complex formula incrementally by rolling the result from one sub-expression into the next.
[...]
It seems like the Magic Trackpad and Apple Pencil would be an awesome pairing.
Yes, this would be great for writing out long-form high school algebra problems. Trig too. I expect this will work well with Pages but I haven't tried it.dewme said:[...] This sounds like it will be easy enough to break down a complex formula or proof into separate parts by using the variables from one or more sub-expressions to calculate the final result, with each of the saved variables holding the intermediate results. This would be interesting for writing a document that has a textual description of a problem and then using the hand drawn math formulas for each step along the solution to make the results come to life within the document itself. Truth be told, this sort of capability implemented as an embedded component would be equally at home in Pages, if there was a way to embed handwritten formulas on a Mac.I wonder how portable these Math Notes will be? Will there be an export to PDF or something similar so I can share the entire text + math worksheet with others?Since it's in Notes, which allows exporting to PDF (and others), the answer is it'll be fine, though if you want shared editing, you'll have to stay inside Apple's ecosystem. -
Apple's new diversity exec hails from Bank of America
No, we don't. We are the default. By definition, as the majority, diversity means those who are not like us.9secondkox2 said:[...] white people contribute to diversity,
We *have* equity. A ridiculous amount of it, compared to other parts of our society. While some of that comes from merit, quite a bit comes from a history of truly evil behavior. Now I am not personally responsible for that behavior, and hopefully neither are you. That doesn't mean we don't have some collective responsibility to work on reducing the harms that *still exist today* due to those evils.[...] deserve equity, and should be included as well.

Foxconn chairman accuses other Apple suppliers of poaching workers in Vietnam
Boo hoo.This is how workers earn more. By being in demand. Don't like it? Too bad, it's just like having to pay more for strategic minerals or any other commodity that's in demand. Especially where unions aren't practical (lack of political cover), it's the only shot they have at improving their living conditions. We're supposed to feel bad about this??

At a crossroads to the future of computing: choosing between Apple Vision Pro and iPad Pro...
Maybe, but I wouldn't be too sure about that. I think all the tech is in place for the Apple Pencil + AVP to turn any flat surface into a drawing surface. Certainly there have been recent rumors about this. Whether or not Apple does this? Maybe we'll see at WWDC.AppleInsider said:[...] Apple Vision Pro will never let me use it as a drawing tablet[...]
