The setup is Amazon vs, conventional publishers. Surely Amazon has done the payoff calculations???
There's a huge difference between A/B testing, designed to optimize your website with the direct intent to improve sales, and performing experiments on how different news feeds affect your users' moods. A/B testing typically comprises changes in button size and color, website layout, font variations, etc; should we lead with the price, or with the benefits, or with something else? On the other hand, what FB and OKC are doing - admitting to, and proudly! - amounts to wholesale experimentation on their users, with undisclosed intent - perhaps to make the users come back more frequently for another hit.
This seems akin to me to cigarette companies manipulating the nicotine content of their products. That didn't go over well when it was finally disclosed.
You can't just tell people you "might" experiment with them, they have to know and understand that they are part of an experiment. They don't have to understand the goal, they just need to know what they are part of, and they have to consent to that experimentation. One could argue that A/B testing should submit to the same level of scrutiny as other psychological experiments, but I think people generally understand and accept corporations' profit incentive. We don't accept the idea that a company might wish to screw around with our mood or set us up on a date when they know it won't work out.
I've actually done exactly that, but not for that purpose. One eye is laser corrected to ~20/25 (degraded over about 15 years to about 20/35). The other eye can find the 'E' on the chart if you tell me which wall the chart is on. When I really need to, I put a contact lens in one eye (which gets the uncorrected eye to about 20/10). Otherwise I walk, read, work, type, drive, fly, etc. with what I believe is called monovision. It's easy. The world looks to me like normal, except that on the one ("bad") side I have very wide range of peripheral vision. I see whatever I focus on in good clarity.
It's amazing what your brain can compensate for. I can't wear glasses, though, that causes headaches.
In the 80's it was well known that the CIA was monitoring the USENET. Apparently there was a list of keywords that they searched for that became well known, so we used them all the time. We had it on good authority that the CIA had become amused by our antics. It probably relieved the boredom.
It's hilarious watching people argue over a topic that has already been shown to be a non-issue. The EIA (US) and German statistics show that, in aggregate, wind-energy sources produce a relatively steady amount of power. Individual turbines and even whole wind farms might not be deterministic, but all the wind farms taken together... are.
I get the message "X This app is incompatible with all of your devices"
is by far the PRIMARY motivator I have of pirating anything. Second is having to reveal my banking transaction codes in order to make a purchase, when I have no trust of either my own system, my connection, or my vendor, third, and LEAST, is the PRICE.
It has been my experience that DRM'd stuff is so finicky and unreliable I might as well throw it away like an old screwdriver whose shaft slips in its handle. Its simply not good for anything. Maybe I can superglue the shaft to the handle to get an operable screwdriver - someone will cry foul, but you know, I'm gonna do it anyway, because I have a screw I need to install and the damned screwdriver won't work.
Except you can decode the salt trivially if you took a cab ride that happens to be in the data set and you recorded the license and medallion number. At which point the salt is useless.
Reality has a liberal bias.
No, reality is reality. The bias is in the observer.
And... that's it? What did SMART say? Did you actually wear the SSDs out as-per the wear indicator? Or did you hit a bug in the samsung controller before the wear-indicator maxed out?
To be fair, the precise situation you describe, particularly if you did not retune the RAID-6 setup or the mysql server, and if the server was fsync()ing on every transaction (instead of e.g. syncing on a fixed time-frame as postgres can be programmed to do)... that could result in el-cheapo samsungs not being able to do any write-combining and cause a 256:1 write-amplication of the data.
With proper tuning the write-amplication could easily be reduced to 4:1 and you would probably be able to run the server with SSDs. Maybe use Intel or Crucial though, and not Samsung. It isn't just the controller that matters... just using stock firmware doesn't really net you a good, robust SSD and there aren't too many real vendors who work on the firmware vs just OEM whatever was supplied with the controller. Intel is probably one of the better ones. They actually fix bugs, as does Crucial. Samsung... I dunno.
Aren't you glad you're not getting all the government you pay for now?
