Breaking Lorentz reciprocity to overcome the time-bandwidth limit in physics and engineering | Science
Telecomms just got a huge breakthrough. But apparently radar guys in the 40's knew about using non-reciprocal resonators to keep EM from pushing back into waveform generators, but never published?

Good for crappy 3G connections, uses UDP, picks up where you left off, so sorta like screen...

Basically Lynx over SMS, which isn't a bad thing, say for emergencies where overall bandwidth is limited. But, SMS has no end-to-end assurances for delivery so dealing with lossy transports is an issue, aggravated by said emergency situation that necessitated using it. How about a a touch enabled version of Lynx as a conventional android browser instead?

Force10 adds rack-topping Gigabit switch • The Register
Interesting large buffer gigabit switch, to better deal with bursty VM situations. Uses cheaper 1Gbps connections too, since 10Gbps still isn't cheap. As long as you are bursty, and don't have raw IO that exceeds 1Gbps, it's an attractive idea.

[ネットワーク性能]70Mビット/秒に迫るWAN速度 - 検証!ニフティクラウド:ITpro
Nifty Public Cloud is roughly 50-70 Mbps on the public network interface, and naturally latency is good due to being a domestic datacenter. Amazon EC2 in comparison only gets around 20 Mbps from the Singapore zone and the latency that entails. Interesting to note that there seems to be few resource controls in place, so the potential for abuse is there. The interesting side note is that Nifty Cloud is a VMware ESX(ESXi?) deployment it seems, because they are using the VMXNET 10Gbps network driver, which allows some virtual machines potentially 5Gbps of throughput on the internal interface. The raw network performance alone seems to trounce Amazon, and Amazon would be hard pressed to match it even with a domestic Japan zone. There is no mention of what time of day these tests were conducted which is suspicious, because of night batch jobs and data dump effects, as well as well known net gridlock times such as lunch and just after the end of the official working day.

Tricks to deal with torrenters, by setting up user bandwidth on a bucket basis. Stay below the bucket limit, you can burst at wire speed. Go over, and you are suddenly at a crawl.

Fibreless fibre optics developed by US Air Force • The Register
This would be an interesting alternative in bandwidth congested cities as an alternative to trenching fiber, as you could do a laser mesh network via rooftops. The adaptive optics can overcome the smog/inversion layer issues and maintain pointing accuracy.
