From a 2007 report from Google, the 1 year annualized failure rate for their HDs, not broken up by brand or model, was about 1.5%. Between RMA rates from NewEgg and reported failure rates, 4% seems to be the norm. 0.4% sounds pretty good.
To change any earlier block. Changing earlier data requires later data to be re-written because the write head is wider than the read head. As long as you append data, you're fine. There in lies the rub. How do you know if you're near the front or back of a shingled region? If it's always per track, then that information is available. Even then, most/all file systems don't care. OpenZFS will care in the future. CoW nature plays well with being able to almost always append to these regions, reducing the amount of re-writing.
OpenZFS has been working to become aware of shingled storage. The CoW nature of ZFS already plays well with shingled recording, but it will become much better once the FS is aware of the layouts. In theory it's not much work, in practice, it's a lot of refactoring.
With modern equipment, they don't need to tear up the roads. I guess they're called horizontal drills. They used them all around my city. Not even traffic interruption while running lines under the road. https://en.wikipedia.org/wiki/...
That's pretty crappy. My ISP uses Ethernet for everything, including voice and TV. They had to run Cat5E throughout my house. My friend built a new house with no CAT and he said they ran the cabling through his dry-wall like pros. All "free" of course. If my podunk ISP can afford to run CAT in every house in the city, then Comcast can easily afford to fix or re-run COAX for a small number of customers.
Which do you believe is the cause? Do you believe such people resorted to reason when their natural behavior was not accepted or that their natural behavior was not accepted because they reasoned through their decisions? Which you assume will greatly affect how you perceive the world.
Probably like the nature vs nurture, a mix of both.
I have been starting to believe that the main difference is personality. Potential be damned, if you don't have the obsession or passion, you'll never exercise your ability. Hypothetical. Two people with equal potential, but one has been fervently exercising their ability to critically think since the age of two and the other just started to notice at the age of 20 and even so only exercises their ability when required or forced. Will the later ever catch up to being remotely close?
Everyone I know has had traits that are to their parents' disdain from a young age. No one is an easy child, though some mindsets are easier to accommodate at some ages than others.
I mean as in were so different that they were ignored because their parents couldn't relate or actively discouraged because their parents tried too hard to "help". A sub-optimal to hostile learning environment.
And I've met people who were absolute trained cogs in the system until they were faced with a question they could not dismiss, a concept that did not fit their lessons
So they do exist. Everyone(Not many people) that I've ever met that were smart enough to recognize a question they could not dismiss, but not a critical thinker, just didn't care. Everyone else doesn't seem to recognize when something does't fit their lessons. I guess I subscribe to bimodal bathtub curve where there is a high separation and few between.
dismissing a population as having no potential to think for themselves just makes you a modern eugenicist
Yeah, I don't like that either. On the other hand, I firmly believe there are many forms of intelligence, critical thinking being only one of many. I also believe perfect is the enemy of good. Eugenics tries to create perfect by using flawed metrics of intelligence and usefulness. This is one topic where I would rather use science to create a pound of cure than an ounce of prevention(eugenics).
Overall I highly agree with you, but only so much that teaching children to question "truth" is a good trait. But on the other hand I'm thinking of these children as if they're more like pets that need to be trained. There are many forms of intelligence, but I'll focus on critical thinking and fluid intelligence. All intelligent people that I know had strong critical thinking skills from a young age, even to their parents disdain. Many of these people were treated as "different", and in spite of all of the social pressure to fit in and teachers trying to make them like everyone else, they continued to do what they enjoyed, learning.
Should I think of the general populace as a bunch of idiots that need to be trained or should I think of them as intelligent people that will be smart regardless of the education system because they can self-educate? If you need your hand held(trained/educated), you'll never fully learn critical thinking because by definition you cannot think for yourself. Of course education/training at it's core is very important because there are a lot of necessary skills required to function as a society, like communication and basic math, but when it comes to higher learning, it's not an issue of being taught, it's an issue of being able.
You can't train CS. Ever see the damning stats related to CS and programming in general? 80% failure rate in the first two semester for people who WANT to get into CS or programming. Then another 20% drop out along the way, and of the remaining 16% who applied, 50% of them only pass because of a strong will, but are otherwise horrible. Of the remaining 8% who have even the slightest knack, their skills are distributed on a power curve, leaving 80% of them below average.
We don't need a strong push for more people in CS, we need to find better ways to help support those that would be good in CS to get into it and afford it.
I have never seen a class that teaches critical thinking, only classes that talk about critical thinking. Is it something that can be taught? It sounds an awful a lot like increasing one's fluid intelligence. If you actually look up fluid intelligence and critical thinking, you'd think they're talking about the same thing. Not quite, but close. Very possibly the same thing from a different angle.
I've seen quite a few research topics on how practicing Dual N-Back or what-not can increase your working memory, working memory is highly correlated with fluid intelligence, intelligence has to be able to be taught because it lines up with one's ideology, and fluid intelligence tests that focus on working memory show increasing your working memory increases your scores on the tests meaning you now have better fluid intelligence. Except, no. Turns out all of these "brain exercises" that make you score higher on fluid intelligence tests are non-transferable. In short, you're just gaming the tests.
I assert that tests that "measure" fluid intelligence are correlated with crystallized intelligence (education and experience) because they're really just measuring specialized crystalized intelligence that is highly correlated. Some people have very high fluid intelligence while having very low crystalized intelligence, but these people are rare, in the same way good programmers are rare. Actually, the definition of fluid intelligence is exactly what you look for in a good programmer.
Fluid intelligence is defined as the ability to solve new problems, use logic in new situations, and identify patterns
As far as we know, fluid intelligence can not be taught or practiced, and current tests are easily gamed from practice (aka crystalized intelligence), but without gaming, they're seemingly highly correlated with fluid intelligence, but crystalized intelligence can masqueraded as fluid intelligence.
There is saying that practice polishes talent, but cannot increase it. Determinism can take someone far, but it has its limits. This is why someone with zero experience can run mental circles around someone else who has years or decades of experience.
The issue is this is always about standards. MS sees a standard they don't like and create their own. But standards are useless unless you can enforce them. Once MS's standard becomes popular enough, they go into enforcement mode, which makes their's better.
You endorse harrasing spammy bot/troll accounts? Buying a game is just to raise the bar enough to keep people from harassing each other. Actually, just buy anything on Steam. $0.50 game would suffice.
Yes, and MOG failed horribly. The cornerstone or MOG is that it requires a universal reference frame, which is blasphemy in the eyes of Relativity, it requires a horribly complex algorithm to make all of the measurements of Relativity work while having a universal reference frame, and it turns out in the end, you still have this lingering variable that perfectly matches our current issue of Dark Matter. There is no winning. You just end up with the exact same problems but with much more complicated math.
A Modern Intel is about 150% faster than an Intel CPU from 5 years ago. Mostly IPC and SIMD improvements, only a mild frequency boost. That's edging on 3x as fast.
My wife's 3.5Ghz 14nm Skylake was cheaper than my 3.3ghz 22nm Haswell, and that's not even factoring in that my Haswell was on sale and also not including inflation. Lithography may be technically more expensive by some metric, but the retail prices seem to completely ignore that. There's a lot of variables that drive the price of CPUs, and even with production being a large part, they're still dropping in price, slowly.
If you think sanitizing inputs protects against SQL injection, I have a bridge to sell you. You need to parameterize/prepare your inputs, which separates your commands from your data. If your inputs cannot change your commands, then all it well.
You can make your pictures look better when you have the raw 48bit color depth and several extra dimensions of brightness to play with. My wife's wedding dress outside was causing white-out from what seemed to be over-exposure. But once you opened up the RAW in gimp, you can change the curve and suddenly it looked normal while still having a gradient. All of the detail was there, but my monitor couldn't handle the range. Even when I was there in person it was intensely bright, so I could say my eyes couldn't even handle the dynamic range.
Good questions, but in lue of facts, compressibility usually goes up as bit depth and resolution goes up, and it seems cell phones are taking greater than 4k resolutions.
Science says you're wrong. On average, movie piraters spend about 2x more money on movie entertainment, like going out to movies and purchasing movies. Science has also shown that people who pirate increase demand in others. Pirating is as much a "lost sale" as advertising that fails to influence 100% of its viewers.
People can't tell the difference between 720p and 1080p in the same way people can't tell the difference between 30fps and 120fps. I guess most people are blind.
That little rant being over, you can tell the difference if you know what to look for. The same way I can point out to people that the music the DJ is playing is a low quality MP3 because I hear audio artifacting.
There was a paper at ASPLOS two years ago that showed that you get a 30% delta on most programs from randomised code layouts just from different cache interaction
What's funny is when someone micro-benchmarks the heck out of something and shows me empirical "evidence" that their code is faster than mine. Then they put the code into production and their code is suddenly running really slow under heavy load. Throw in my code for S&Gs and suddenly the service is running much faster, and I don't even put much effort into the design like they do. Many people fail to understand how processes within the system interact with each other when it comes to cache and memory bandwidth. Even when I try to explain my theory as to why my code runs faster, their eyes glaze over. And that's why many of our services run like crap.

Even better. Combine "New wallet with each transaction" and "Report every wallet" and you have a recipe to DDOS the service.

Nice link of how not to use MS SQL correctly. General rule of thumb, you can't fix stupid. They will always find a away to use tool incorrectly.

In other words, a 100% increase in performance of a micro-benchmark can result in a 10% reduction in the macro-benchmark.
PnP sucked during the transition. It didn't always play well with non-PnP devices.
