It depends on how the error occurs in the output. If all the pixels are off by ~1% in their RGB values, it will be barely noticeable. If 1% of the pixels have a random wrong color, it could look very bad. For instance, assume a 4k monitor (3840x2160), which has ~8.3 million pixels. If only 1% are bad, that's 82,944 bad pixels.
Given people are very frustrated by even a single stuck pixel, 83,000 would be horribly annoying, especially if there's very little noise or busyness in the image.
Note: I have no idea how the error occurs in the output, or what future algorithms may be developed to deal with such error.
My Piano teacher has perfect pitch and can tell the difference (without a tuning fork) between notes that are in-tune and notes that are out of tune. A few percent difference would certainly be something she'd notice. A4 is 440Hz, while A#4 is 446Hz, which is an increase of only 1%, and she can tell the difference of fractions of that. All individuals with perfect pitch would be able to tell the 1% difference between A4 and A#4.
As you stated, in general, most people would not be able to notice small differences in absolute frequency, only relative frequency--provided those differences are relatively small (within an octave or so on a musical instrument).
It's unclear to me if the 1kg and 25000kg ball have the same terminal velocity, but the side cores and center core aren't the same shape. The center core is taller...
Assuming both objects are falling on their face and not flipping (the way that the Falcon 9 travels), a penny will fall slower in atmosphere than a long cylinder with the same density and area, even if the orientation of travel of both is in the direction of the surface of the penny. This is because the air resistance of the penny per unit of mass is much higher than the long cylinder. The same aerodynamic effect can be seen on road trains, which accounts for their improved fuel efficiency.
The center core is also likely denser than the side cores. We know the center core is reinforced to handle the additional structural loads. This would further increase the terminal velocity.
Maybe they disagreed with their companies' actions and felt that they had a social obligation to speak truth and no other way to achieve said goals.
Or maybe they're egotistical and enjoy wielding secret power... or any number of things.
I'm personally going to hope the former. Lots of leakers speak truth because they believe that the "needs of the many outweigh the needs of the few, or the one"... usually to their personal detriment. Ellsberg, Snowden, Manning, just to name a few.
Yes, you can do exactly that. My son upgraded from a C2Duo to a 2.8 GHZ C2Quad for $25. The extra two cores would more than compensate for the performance losses from these OS fixes.
Doesn't always work if you have a laptop (many CPUs are soldered in these days), and it does involve some cost on your own, especially if you don't do the work yourself.
Core 2 doesn't just run Ubuntu perfectly fast, it runs modern games perfectly fast.
My son's computer is a C2Q 9500 with Windows 10. There's no specific release date published on Intel's ARK, but C2Q 9550 released in Q1 2008 (10 years ago!), so it's at least that old. He plays Overwatch on it in Ultra Quality at a constant 60 FPS (limited by his display). That's a 10 year old computer (with a newer GPU) running games at full speed that you're "supposed" to buy multi-thousand dollar computer setup for. He got it on Craiglist for $50, plus a couple spare parts I had lying around and a $150 GPU.
CPU scaling has really slowed down--a 10 year difference used to be a world changer, and now 10 year old CPUs are fast enough.
Snapdragon 845 is scheduled to release this year. It will have the Meltdown flaw and it won't be Intel. I know you have a emotional desire to repeat that meltdown is Intel only, but it's not. Grow up.
That's good to note. I wasn't aware that no A75 hardware has yet shipped.
That said, the design was finalized and released in May of last year... so something will have to be done by anyone implementing it if that hardware is running untrusted code.
Thank you for noting that you're not 100% sure it's right, and for the excellent summary. There's a ton of misinformation going around, especially with 0100010001010011 dude on Slashdot repeatedly posting that Meltdown is INTEL ONLY, which is false, as some ARM products are affected. What is true is that Meltdown does not affect AMD and affects only a few of ARM's processors.
Here are two corrections to make: 1) Meltdown:
One of your bold statements "AMD and ARM are not affected" is untrue. See here, from ARM directly: https://developer.arm.com/supp...
ARM has confirmed that A75 is vulnerable to Meltdown. In addition, A15, A57, and A72 are vulnerable to a variant of Meltdown (Variant 3a) which ARM has added. ARM has stated that they believe this variant is NOT exploitable, however, there is already userspace code out there that can do some limited exploits: https://github.com/lgeek/spec_...
2) Variant 1: While other vendors may require application changes to address this issue, AMD appears to be able to address this with an OS update, based on their post: https://www.amd.com/en/corpora...
Summary: Variant 1: Some manufacturers (ARM) appear to not be able to fix it and are recommending compiler changes, but AMD will fix this in OS updates. Unclear how Intel is addressing this vulnerability. Variant 2: Correct, from what I can tell. Variant 3 (Meltdown): Affects nearly all Intel (within the last 10 years) and ARM A75 chips. AMD not affected. Variant 3a (Modified Meltdown): Affects a larger set of high performance ARM chips
Finally, Intel has done a terrible job (intentionally?) at conflating the two issues, which is unfair. These are 3 separate security issues, with their own priorities and impacts. If you read Intel's official press release for this issue, there's no differentiation between variants 1-3, like there is for AMD and ARM: https://www.intel.com/content/...
It's definitely a peak power thing. The shutdowns are dependent on the workload of the device. If I leave the screen off or refrain from any 3d apps, it'll usually go way below 15%, but it'll shutoff at 15% in a game. My wife had a similar experience. I just know that 15% is the level at which my Nexus 6 may randomly power off.
The Snapdragon 810 is well known for being a power hog.
Also, your statement isn't necessarily true. From the researchers:
At the moment, it is unclear whether ARM and AMD processors are also affected by Meltdown. https://meltdownattack.com/
No. Spectre affects AMD and ARM as well (and likely other architectures too).
Best I can tell, the only CPUs guaranteed not affected by both are in-order architectures, which many older ARM (and extremely old x86) chips are.
These attacks are a sort of new category of security analysis--realizing that out of order execution can have side effects, and that programs can check for those side effects to leak program state and system memory.
Other phones definitely DO shut down suddenly. My Nexus 6 shuts down at around 15% battery left. My wife's shuts down at around 40% battery left. We replaced her battery, and the problems went away. The phones are over 3 years old now, and batteries do wear out.
This was a fixed-price lottery ticket, not a jackpot style scenario. Payout was $500 per ticket.
People the article interviewed went and bought tons of tickets, seeing that most were winning. The article cited winners of $18,000 and $10,000 complaining that they were worried they would lose their winnings. I think after you win 36 times, mostly in a row, you know something is up, and you may not win the full $18k.
But they should still win at least the first $500, IMO.
No, he's saying to stop shouting racial slurs, advocating for fascist rule, and associating with people that murder others. A pretty sound argument, in my mind.
I either don't understand your distinction between actual Nazi and identifying Nazi, or why it matters. The whole movement is around racism and fascism, and anyone identifying with such beliefs is misguided at best and dangerous at worst.
The fact that Nazis haven't successfully committed genocide in the modern day is simply a lack of ability, not will. Arguing on their lack of success is a pretty fallacious argument. If they had power over the government, you could be pretty sure they'd be trying to commit genocide. And don't act like Nazis are so harmless... even without having control over the government, they're still committing racial and ethnic-based murder. That they haven't been genocidally successful isn't much of a comfort.
I'm totally fine with marginalizing them! Ethnic cleansing and violence are BAD. We SHOULD argue with them, we should tell them they're wrong, we should convince them of such, as much as is possible. We should NOT accept their viewpoint.
But we should treat them as human beings, because that's what they are. And if they want to say things that are horribly wrong, offensive, and racist, that's their right--but we should challenge them! Bringing the topic into the open, discussing it, and rebuking it is the only way to change their mind. Suppressing people's views will only result in violence. People either express their views and frustrations with words, or with violence. And I am strongly against violence.
Before you say free speech can't work, it can. If someone can leave the hell that is the Westboro Baptist Church, then ANYONE has a chance.

I said that it seems to me that both being trans and being a Nazi could be proved by using science. I asked you to explain their statement: "At least this is based on things people provably say rather than anti-science nonsense". It seems to me that I could prove, using science, both that someone's statements indicate they're a Nazi or that they're trans.
I also said that while I personally abhor certain speech, I believe in free speech, even if it's repugnant speech. I believe in the freedom of both trans speech and Nazi speech. Finally, I stated that free speech was a virtue specifically so that marginalized people could speak for their rights.
Advocating for minorities to be able to speak to their viewpoint is "worse than Reddit"? Interesting world.
The stalking is harassment and wrong in both cases. How is your being trans and more or less provable by science than their being Nazis?
If you're saying we should shut down all Nazis speak because we know it's bad and should be silenced, I'm going to disagree with you. We knew being trans was bad 20 years ago too. Was it right to shut down all pro-trans people then?
Free speech is worthy of being defended, specifically so that people like you can change the hearts and minds of people, and therefore the culture. The side effect of free speech is some of it is bad.
I wasn't getting ready to retire, but move. I gave 9 months notice, then kept open dialog with my employer. They were extremely grateful to have the headsup warning (as I'm a key employee), and actually when it finally came time for me to leave, they said "oh, you think you're leaving?"
Long story short, I now work from home with a really sweet job where they pay me to fly back to work occasionally (and hang out with my family). I work out of my home the rest of the time where I make good wages from a wealthy job region and live in a low-cost of living area. Imagine living in northern CA but making Silicon Valley wages. I don't even pay to visit my family.
I made this decision because:
1) I knew I was a key employee, and the chance that they would actually want me gone was very low AND
2) I trusted them. I worked for a reasonably small company that knew and valued their employees and treated them well.
If either #1 or #2 weren't true, I probably would have only provided a 2 week notice. If they had actually laid me off when I first gave notice, it would have royally screwed up my finances at the time.
I know there's a lot of cynical (and for good reason) people here who said that business is just out for its own interest and you need to watch your own, but I've found that being consistently generous, caring, and selfless has actually gotten me quite far in life. I work for companies who treat me as a person, and I give them my all in return. Given it's the type of person I want to be and the one I feel God is calling me to be, I have no plans to change. It's one of the reasons I refused to work for a behemoth company out of college.
The best safe plan I've heard, if you're willing to work a little extra, is to wait until you're ready to retire, give them 2 weeks notice and let them know you'd be willing to stay around for 6-9 months to help crosstrain. That way, you either retire when you want or you work a little extra and have a little extra at retirement.

For people who found it was a glitch and repeatedly bought tickets, I can see some argument for only paying the first.
But what will likely happen is some lawyer will cite some obscure contract language and nobody will get anything. I hope I'm wrong.
I LOVE that link. That's so awesome to hear, and free speech and love truly at work.
