Why do you think demand cannot be sustained ? Bitcoin is a payment system. If you want to use it you need to purchase some bitcoin. The amount of bitcoin is largely irrelevant. You purchase for a certain value. If the value keeps going up you just get less bitcoin for the same value. But you can still use it for transactions for that value. Bitcoins are basically infinitely divisable. The current minimum amount of 1 satoshi can easily be subdivided.
When you think of bitcoin only as an investment vehicle it's true that is has no value. The value is generated by trade in the form of transactions.
The measurements were not done on the ground or with GPS assistance. The payload of the Sentinel-1 satellite they used is the CSAR radar. That radar does automatic distance/altitude mapping of entire swaths. I'm just amazed by the precision.
Wow, mapping a buildings from space with millimeter accuracy. From an orbit 693km high. That's an accuracy of 1:100,000,000 while flying 24,000 km/h.. Crazy. And then imagine the capabilities of really good US satellites aren't even known because classified.
The Merlin engines of the Falcon 9 use RP-1/liquid oxygen as fuel. If the new Glenn uses liquid hydrogen/liquid oxygen as fuel that would explain the size difference.
No one compiles their own kernel these days.
That's not true. I still compile custom kernels and I know a few others that do so too. However to do so is a choice these days and you better have a very good reason to do so because distribution provided kernels are perfect for 99% of the use scenarios. I have a very good reason: I think it's fun. I'm weird that way.
Plus I create custom hardware. But many times even that is not really a reason for compiling a custom kernel with the user space driver options.
When an friend an I got started with Linux he wanted to remove his Slackware install from a dual boot PC. For fun he ran rm -rf / on that install. We had a good laugh when the message scrolled by of the OS trying and failing to remove files from the CDROM. That was until he realized that he had mounted his Windows partition too. It didn't fail to remove files there
As slashping says the cable is manufactured in segments. However your mental image is not that far off as the segments are pretty long and need specialized ships for laying them. See for example http://offshore-fleet.com/data/cable-lay-vessel.htm.
Please do make a donation option. I use an Ad Blocker because I find the ad business toxic. I will not turn it off. Not even for Slashdot. But I do want
While you're at it please add IPv6 support too. IPv4 is getting slow here with NAT up on NAT.
So basically you say this is the embrace step with an extend step to follow by using binary extensions ?
Using fiber or copper on the other hand reduces the maximum distance with 30% due to the slower propagation of signals in those media.
Sigh, the reason Juniper etc use BSD is because of the licensing, not because it's better at networking.
You can take BSD, modify everything and not have to share those modifications with anyone. So it's a great base to start building your own proprietary system. The real networking stuff in machines made by the vendors you name isn't done by the normal FreeBSD kernel but by software custom written by those manufacturers. Of course they will not back port this software to FreeBSD proper as it's the product they sell. If real heavy networking is going on its done by ASICs like Junipers Trio chipset.
If Microsoft doesn't have the intention to distribute their Linux version the licensing isn't a big deal. And there may be reasons why Linux is a better fit in their circumstance like the much more expansive hardware support.
Maybe you've heard of Arista ? Their kit runs on Linux. They must be stupid.
The only -current- viable source of tritium is fission. However fusion can produce its own tritium in breeder blankets. This is one of the concepts that will be researched in ITER: https://www.iter.org/mach/trit...
So the last part of your post "but it's not a viable power source unless the need for tritum is eliminated" is just wrong.
Some of my readers ask me what a "Serial Port" is. The answer is: I don't know. Is it some kind of wine you have with breakfast?
