I have a Vive pro with a wireless modules which uses WiGig. And it works perfectly. The delay is negligible and you don't see the difference with a tethered headset. The only drawbacks are that WiGig doesn't penetrate anything so the screen goes grey when you block the line of sight your body and the battery only lasts about two hours so if you play a lot you need two and be prepared for an interruption after about two hours.
That's already done. The Microsoft datacenter a few miles from here delivers warmth and CO2 to the nearby greenhouses. See https://investinnhn.com/invest...
Iridium satellites cost about $5 million per piece. So your cost estimate is about 10 times to high. Launching and operating will cost a pretty penny too but if the system supports about 10 million subscribers the cost of a subscription will be in the same order as a dsl or cable subscription.
The i7-7700k runs at a turbo frequency of 4.5GHz. Thats 10% faster than the maximum frequency of the X1800. The rest of the performance gain is better IPC. However the i7700K also has a TDP of 91W which is almost the same as the 95W TDP of the X1800. If intel doubles that chip it will melt down unless they scale back the clock speed. And you wind up with something that performs less than the i7-9600 which performs at about the same level as the X1800. So nope, not going to happen any time soon. What I'm wondering is what will happen with the release of the 4 core Ryzen processors. Will the reduced power requirement allow AMD to up the clockspeed to a level where they beat the i7-7700K ?
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.
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.

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.
Easy: Just add prefixes to the numbers and everybody is happy. The old numbers stay valid, you can still connect within the old network(s), nobody has to remember new numbers.
You have no knowledge of IP have you ? To follow your telephony analogy: an "IPv4 telephone" can only dial numbers with exactly 10 digits. If you are going to expand the address space by adding a digit you will have to change all those "IPv4 phones".
Without the analogy: IPv4 addresses are 32 bit and every IPv4 stack defines them as 32 bit numbers. To address more than 2^32 nodes you will have to adapt every IPv4 stack and redefine addresses as something bigger, say 2^128. And that is exactly what IPv6 does.
When you redefine your address you will get incompatibility. A node which still has IP addresses defined as 32 bit will not be able to send replies to a node with a 2^128 address. The destination address simply does not fit in the defined address space. So while a node with an updated stack might be able to send traffic to a node without an updated stack that last one cannot send data back and you won't have meaningful communication.
That being the case it is better to make it clear that an expanded address space is incompatible with the current stacks. And that is exactly what has been done with IPv6.
Calling people morons without have any significant knowledge about the problem domain yourself is the real stupidity in your post. Dunningâ"Kruger in full effect
But remembering interviews with Occulus developers there is more to VR than a good resolution and tracking. Things like ridiculous low latency needed to prevent motion sickness and screen artifacts caused by rapid panning. Has Valve solved these things in record time in secret or will this be a better specs on paper but worse in practice product ? Or maybe I'm just falling for Oculus marketing: http://arstechnica.com/gaming/...
There is no 100MHz ethernet. There is 100Mbps ethernet that runs at 125MHz on copper with 4B/5B encoding (and MLT-3 to limit the bandwidth of the signal). The overhead is in ethernet and IP headers, preamble and interpacket gaps etc. Although the theoretical maximum efficiency for TCP on IP over ethernet with an IP MTU of 1500 is about 95% this is almost never reached due to latencies and suboptimal implementations etc. It's quite normal to get 90% maximum throughput in optimal situations.
Well, I've been wrong about what the majority of people want a lot of times. But being opposed to change seems to be pretty universal. So I got reasonably good hopes for this battle.
So basically you are waiting for the new Vive pro Eye ? To bad HTC pricing is so high.

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.
