Tizen is very appealing in that regard and why so many OEM's are looking at Tizen in their devices.
Hahaha bullshit. No one is lining up to use Tizen.
Look for all manner or smart devices [tizenexperts.com] to start running Tizen in the near future.
All manner? Of all the stories on the first page only 6 were about anything but this phone. The top story was just about people wanting Tizen on a compute stick and only 2 other stories were about something using Tizen that wasn't Samsung.
What was not obvious? It's clear there is an anchor tag for W^X which when hovered over shows a wiki article. Seems pretty obvious that was a link to explain what W^X meant for those who didn't already know.
a) Depth perception in darkness changes (given they could use some sort of sonar type bounce to get a distance reading)
There are all sorts of sensors and readings to use to land in the dark especially when automated. You do realize that planes fly all the time in the dark and in fog, right?
b) Blindness of the camera's when the thrusters are activated.
You wouldn't be using only cameras. You would have a host of other sensors to provide all manner of positional information. None of this is new or impressive.
c) Landing on the water, barges move up and down, that's really impressive, it's only so stable. This is nothing like a carrier landing in any way.
Sure, that is impressive, but has nothing to do with being in the dark. Such a thing is tricky regardless of the amount of light.
Care to quote anyone who has ever said that gun control prevents ever single instance of gun violence? I've never heard a single gun-control advocate make such a statement. On the other hand, the US has over 10 times the rate of murders per capita from guns as France.
Slashdot has been posting political stories that have nothing to do with technology for well over a decade. Also the "news for nerds" subtitle was long since removed from the title of the site.
Corner cases? There numerous exampled of people being falsely accused, convicted, given the death penalty and even wrongfully executed. Wrongful accusations and convictions are not corner cases.
And to further support this point. From a Forbes article:
However, despite the strong proliferation and installed base, the QNX business is not believed to be very meaningful to BlackBerry’s financial performance (the company does not break out QNX financials). The business generates revenues through the licensing of QNX software products and through the professional services that BlackBerry provides to customers for developing QNX powered devices. Estimates from Bloomberg peg QNX revenues at just about 2% of BlackBerry’s total sales and IHS analysts estimate software licensing fees at a relatively paltry $3 per vehicle.
So something that is estimated to account for less than even 5% of its revenue is not going to save the company from imploding.
Plus they have QNX which is used in billions of devices around the world. So what if their handhelds aren't popular? Who cares? They will continue to have a niche market in handhelds.
Which doesn't mean much if it doesn't generate that much revenue. They bought QNX for $200 million. There's no way that's what one pays for a business generating lots of profits.
Memory mapping the disk will remove the read and throw away part.
Wrong. Assuming by "memory mapping" you mean "mmap", it pages things in and out of memory all the time.
Your argument is that since memory is faster than disk IO it is better to do (1 disk read + 1 memory write + 1 memory read + 1 conversion) rather than (1 disk read + 1 conversion)
It is. It's magnitudes faster to keep things in RAM.
Of course, it is a way to read and write from/to a file with less overhead.
Sure, different memory-mapped I/O methods can eliminate certain overheads. DMA eliminates CPU overhead. mmap allows you to pull in data from internal/external storage into RAM so that you can access it faster, but you're still suffer the overhead of accessing the SSD whenever things are paged into and out of memory. Neither one magically changes the fact that accessing an SSD over RAM, which is what the person I responded to wanted, is 1000s of times slower than accessing RAM.
There's nothing unfortunate about it. Access times for SSD is around.1 ms vs at worst around 15 nanoseconds for DDR3 RAM. You do realize how significant of a performance impact that would be, right?

Especially when W^X had a link to a definition.
Sure, if someone ports it over. They do share features but not all BSD kernels have all the same features.
It's a feature I don't think about anymore, and I find myself mistakingly trying to use it while under Windows.
Then remap the action of your middle mouse button. I've been able to do that with every mouse I've owned in Windows for more than 15 years.
Could you not tell by the ":-P" that I was joking? The aspergers is strong in this one.
But have they fixed the memory leaks yet? :-P
*ducks*
No, free countries allow even speech that is filled with hatred.
Horrible troll is horrible. First sentence of TFA says "bipartisan group".

Well, I think it's a milestone. Just getting it to land on the platform, in the dark, without any human help.
What is all that special about landing in the dark? You do realize we have all sorts of cameras that can "see" in the dark, right?
No, I think he's implying that coding has gone out of fashion (or at least no longer guarantees a high-paying job.)
Coding going out if fashion? Have you been living in a cave these last few years?

they went from a computer company to a mobile device company.
That doesn't make any sense. Apple is still a computer company. That and mobile devices are computers.
Plus they have QNX which is used in billions of devices around the world. So what if their handhelds aren't popular? Who cares? They will continue to have a niche market in handhelds.

Exactly. That is all mine is as well.
I don't need to. My bill is exactly as I stated. Seems you have a shitty utility company.

Memory-mapped I/O is already a thing.
Yes, it is ancient. So what?
Of course, it is a way to read and write from/to a file with less overhead.

Now we only need to get them memory mapped and good OS support for not loading constant data to volatile memory.
Even with PCIe 3 access times for RAM vs an SSD still favors RAM extremely heavily. Enjoy your system slowing to a crawl by doing that.
