When I last looked into this, I googled electric motors in the +30MW range and found that some gas pipelines use electric turbines of that power. These are massive, stationary engines which made me wonder if the weight of the motors might b

I wonder if decentralized voting for NNTP could actually be a good use case for some kind of block chain.

Fusion reactors also consume a lot of energy. ITER plans to have a gain factor of 10, making 500MW of heat -- not electricity -- out of 50MW. According to wikipedia, a gain factor of 22 would be needed for commercial operation. The record i

Fusion power will be as 'free' as wind power. Both technologies struggle with high installation cost that has to be distributed over the number of customers and the lifetime of the plant. For fission power, the installation is alr

Going for the expensive toy niche of the market was really brilliant. Technological teething problems and high cost don't matter there as long as it is fun to drive. German car manufacturers used to advertise their hydrogen/ elect

You are right. I simply wanted to illustrate the idea of id/locator split. The mapping of a fixed id to a quickly changing locator is a problem of all those schemes.

HIP stands for Host Identity Protocol. The idea is to separate a host's identity from its location. An IP address does both. It could be argued that DNS already achieves the ID/locator split: The DNS name of your host identifies i

This would not work and it isn't even necessary. Looking at how other low-wage fast-growing countries in the past developed, China's wages and costs will soon get close to Western ones and there will be a more fair competition. Eg

I had former-engineer managers, who were the first to acknowledge that their technical skills weren't up to date. It makes a huge difference if you can explain a technical problem to someone who has solid base skills in the field or if

Every industrial nation started by copying the British. The European countries and the US did it in the 19th century. In the 1960s/70, everybody joked about the Japanese copying everything. In the 80s, South Korea was known for cheap c

It's about telephony traffic, not data traffic from phones. Some national regulators publish the numbers every year. https://www.linkedin.com/pulse/past-point-peak-telephony-dea... has some discussion and links.

Phone traffic on the whole has peaked recently, at least in western countries. If websites caused more calls, this should not have happened.

Publicy funded institutions pay for the scientists that write the papers and review their colleagues' papers. And then the public has to pay Elsevier again for the right to read the papers. It is an absurd system. The value added by th

That's true. ITU-T standards (eg for ATM and OSI protocols) used to be really expensive. Buy one 8 page document for 50$, realize that this is mostly a collection of references to other documents, keep buying until you have all the inf

A genetic algorithm designed an FPGA logic that couldn't possible work under usual rules, but actually did and used less resources than any human design. As it turned out, the genetic algorithm exploited some analogue properties of the

Good analogy. TV and many web sites feel like a road at very touristy place where you get constantly harassed by people trying to get you to visit their bar or sign time share condo contracts.

Catimor is a variety of arabica, not a different species like robusta. Excelsa seems to refer to the Colombian coffee grade which may include different arabica varieties.

Microsoft Edge implements ORTC. The problem is, the IETF RTCWEB working group was/is dominated by players from the SIP world who wanted to re-use their existing code. The argument was that WEBRTC devs would never need to touch the SDP,

Combine it with WebRTC and implement T.30. Find a WebRTC/SIP/PSTN gateway. Send a Fax from the browser!! You might laugh, but we do have an API for sending DTMF tones in WebRTC..

You need a way to exchange the SDP message contents between your browser and the remote browser. How you do this is up to you. A central server is just the simplest way to do it.

The telephony argument for SDP was brought up a lot in the IETF. However, few SIP devices -- if any -- understand all the SDP extensions WebRTC has introduced. With RTP/RTCP the situation is even worse. You always need a gateway.

For p2p, you already have the webrtc data channel which handles all the nasty NAT traversal and DDoS issues. Its browser API should be less volatile now than it has been in the past. Implementing a WebRTC data channel endpoint in a server i

In the days before general car ownership, you had small shops in walking distance. They were no longer competitive once shopping centers near the highway could shift the cost of delivery to their car-owning customers.
