If you cannot afford to buy something with cash, then you can do without it.
There have been serious suggestions here in Norway to forbid cash payments for various things. This includes buying tickets from bus drivers, paying at restaurants and for purchases above some threshold (think 2000 USD and such).
The bus drivers don't want to have cash because of robberies, the tax administration wants to make it harder for restaurant owners to cheat, and the police wants to make it harder to launder money.
We're not there yet, but I'd say it's coming soon.
If one can spell apoapsis and periapsis correctly, surely one can spell "brake" and "braking" correctly.
Can, yes. Will always... apparently not.
For some reason I don't quite understand I've been rather sloppy on break/brake lately. Then again, I write way less English than I used to (it's my second language).
Oh well, thanks for the heads up, clearly I need to pay more attention to what I write.
Why would they perform a braking maneouver resulting in orbit outside Callisto?
Juno is planned to have a very elliptic orbit. It will go close to collect data, then move far away to have time to send the data back to earth. They want to spend as little time close to Jupiter as possible to minimize radiation damage.
Also, the larger apoapsis means they can expend less fuel when breaking. If you just want to be captured, you get as close as possible to the planet and break until you're just gravitationally bound, which will result in an orbit with a very large apoapsis and very small periapsis.
What's so terrible about Bandcamp (which is the digital music service I love)?
They seem to be doing pretty good, they're growing as well as being profitable.
Best part (IMO) is that they also have lots of artists saying they appreciate Bandcamp. Here are some comments from that blog post:
Bandcamp is the greatest platform for independent artists. I am glad to be a part of it, without it getting new fans would be difficult.
We release small independent music compilations since three years here on BC. We worked together with more than 200 artists in these years. The most of them publish their music on BC too. I can confirm: More people buy the music on BC. That is what the musicians say in talks. And even our pay what you want releases have a really good perfomance.
I've bought a lot of really great music on Bandcamp, the artists like it. So yeah, what's so terrible again?
I had the exact same reaction, but then I spoke to a buddy of mine who had recently been lent a Tesla with the Autopilot while his older Tesla was being serviced.
He's a salesman so spends a large amount of time on the road. He said he really appreciated the Autopilot, because while he was still in "driving mode" (hands on wheel, eyes on road, feet ready), it allowed him to reduce his attention level a bit.
This again allowed him to focus a bit more on work-related phone calls (via his quite excellent hands-free, first few times I didn't notice he was driving), which made him more productive on the road.
Then again he did describe it as a more advanced cruise control, which is what it is, and why I agree that Autopilot is a bad name.
This[1] article says almost $100 million per year for the Hubble. So they'll have to compare how much science they could get per year for $100 million if they spent it on other projects.
But as long as it's fairly functional I imagine they'll keep it up there.
And why isn't it detecting waves on a daily basis? The universe is supposed to contain billions of black holes.
The black hole merger that was first detected had a peak power output that was 50 times greater than the total power output of all the stars in the observable universe.
The waves from that merger caused the arms of the LIGO detectors to differ in length by 0.000000000000000000001 meters, which is roughly like the earth getting wider by 10 protons.
This latest merger involved less massive black holes which should mean it had a lot less peak power.
If you're referring to the actual compiler (cl.exe), there's a 32bit bit version, a 32bit cross-compiler (outputs 64bit binaries), and a native 64bit version.
The article is talking about the IDE itself, not the build tools. It will use the 64bit version of the compiler for building 64bit applications if your OS is 64bit.
I've got a debit card and have a repeating transfer set up at my bank to transfer a set amount each month into the account connected to the debit card.
Then I get a friendly reminder if I try to overspend: the card transaction is denied.
If I really want to buy it anyway, I just fire off an SMS to my bank to transfer a bit more and retry within seconds.
I don't have a lot of expenses so once a month is enough to keep the amount low, to limit the risk in case something happens to my card.
IPv6? Really? This is 2016: I've had dirt-cheap routers with IPv6 support since forever.
Maybe that's what I've done wrong then.
I've been using a high-end Asus router which only got proper IPv6 support sometime last fall. I'm now using pfSense, which only has limited IPv6 support.
In the rush to find gravitational waves, it doesn't seem like the other, more plausible explanations have been ruled out.
Really? Did you read the paper[1]?
High strain sensitivity also requires that the test masses have low displacement noise, which is achieved by isolating them from seismic noise (low frequencies) and designing them to have low thermal noise (intermediate frequencies). Each test mass is suspended as the final stage of a quadruple-pendulum system [56], supported by an active seismic isolation platform [57]. These systems collectively provide more than 10 orders of magnitude of isolation from ground motion for frequencies above 10 Hz.
To monitor environmental disturbances and their influence on the detectors, each observatory site is equipped with an array of sensors: seismometers, accelerometers, microphones, magnetometers, radio receivers, weather sensors, ac-power line monitors, and a cosmic-ray detector[65].
Exhaustive investigations of instrumental and environmental disturbances were performed, giving no evidence to suggest that GW150914 could be an instrumental artifact [69]. The detectorsâ(TM) susceptibility to environmental disturbances was quantified by measuring their response to specially generated magnetic, radio-frequency, acoustic, and vibration excitations. These tests indicated that any external disturbance large enough to have caused the observed signal would have been clearly recorded by the array of environmental sensors. None of the environmental sensors recorded any disturbances that evolved in time and frequency like GW150914, and all environmental fluctuations during the second that contained GW150914 were too small to account for more than 6% of its strain amplitude. Special care was taken to search for long-range correlated disturbances that might produce nearly simultaneous signals at the two sites. No significant disturbances were found.
A "black hole" (i.e., an object with a singularity) is only one of many such models, but it happened to be one of the earliest ones, which is why the name stuck.
From what I understand, the current definition of a black hole is not an object with a singularity, but a region of space surrounded by an event horizon.
There is 0 evidence that what we call a "black hole" is an actual real class of objects that really exist.
Black holes is a prediction of our theory which matches observations so far. A recent example is the black hole merger causing the gravitational waves detected at LIGO.
Unless we find a different theory which matches observations better and which says that black holes are in fact not black holes but something else, we will think of these objects as black holes.
Theory suggests that black holes cannot form because they would require infinite time to collapse.
This is plain wrong. The collapse happens in a very short time, in the proper frame of reference.
The SFC is not the owner of either of the works in question and is not the author of the license in question. They have no stake or standing in the matter.
It seems they do have a stake:
The GPL Compliance Project for Linux Developers is comprised of copyright holders in the kernel, Linux, who have contributed to Linux under its license, the GPLv2. These copyright holders have formally asked Conservancy to engage in compliance efforts for their copyrights in the Linux kernel. In addition, some developers have directly assigned their copyrights on Linux to Conservancy, so Conservancy also enforces the GPL on Linux via its own copyrights in Linux.
Khronos Group is responsible for the OpenGL and OpenCL standards.
They've had a lot of internal fighting over the future of OpenGL for many years. Real-time 3d engine developers (ie games) wanted to remove a lot of cruft and expose the hardware more, while CAD and other groups were happy with how things were. For years nothing much happened. This is the same fight which made OpenGL 2 so delayed.
Then AMD released their proprietary Mantle API a few years ago, which amongst other things was much lower level than OpenGL or DirectX at the time, allowing 3d engine developers to extract much more from the hardware.
AMD offered Mantle to Khronos which picked it up, polished it and named it Vulkan.
Now CAD folks can keep their OpenGL, while real-time 3d folks can enjoy extracting the maximum from the hardware with Vulkan.
I read it as they rollback in the database sense, so that the account still has money and they just make repeat withdrawals until the machine is empty.

No, not this at all. A lot of people are making this mistake. It's not what the submitter is talking about.
Of course this is not what the submitter is talking about, I never said it was.
The need for high framerate in VR is mainly due to rotation of the head, which is exactly what time warping is good for.
If one were unable to rotate your head and could only translate it, VR wouldn't have the same need for 90+ FPS.
I can't see how motion compensation would do a better job, in fact I don't quite see how it would be any good at all.
So yes, very much "this" indeed.
Look up "asynchronous time-warp". /thread
Pretty much this. Here's a video explaining time warping, it also has some links for more details in the video description.

Why I thought it was because one was science fiction and the other was science fantasy.
Would have been more interesting to do a comparison between two science fiction universes.
What exactly is the point of it?

Why not use it until it's completely broken?

Just create another vdev with the new disks and add it to the pool. Voila, more space in the pool.

Jokes aside, there was an interesting presentation by Mark Maimone at CppCon 14 about using C++ on the Mars rovers:
https://www.youtube.com/watch?...
They use a fairly restricted set of C++ features, but overloaded new and delete operators to avoid fatal memory space issues.
