wait until we have USB-C charged hoverboards (and similar products), where not only can the charger and cable catch fire, but so will the low budget Li-Ion battery pack/charge controller/bat…

The air quality in Karachi and Lahore is really, really bad as well. Spend one work day in Lahore wearing a clean white collared shirt and then take a photo of the shirt...

You really don't want to use DC for distribution in your home. Go price out telcoflex copper cabling (from 0000 up to 4 gauge) for -48VDC datacenter use. Voltage drop over distance and losses to …

"I'll be there in 15 minutes but first Bob has to get me a reacharound"

Little known fact: The Germans in the BMW marketing department at first wanted to name the new "ReachNow" service in Seattle "ReachAround".

They're renting commercial geostationary Ku transponder capacity (by the kHz) like any commercial TV station.

"Modified phones"? What was this, a VoIP company? Hosting? The article is really vague. VoIP over VPN to a centelized server?

Really expensive bikes you just don't ever lock anywhere in public. I don't know anyone in Vancouver who would lock a $3500 road or mountain bike anywhere. You're either in possession o…

The metal insert for bottom bracket (BB30 or not) can have an SN. this is permanently glued to the frame.

Most good GPS receivers will get a signal through an ordinary low cost generic Chinese carbon fiber seatpost. Careful not to get the very cheap ones which are Alu wrapped in a CF laminate.

I am pretty sure you could make a very, very low power watchdog circuit that only wakes up a GPS receiver and 2G/3G modem when it detects 60+ seconds of continual motion. Otherwise it'd slee…

"A huge guy"...? New service like uber: "rent a 350 pound Samoan" VC money please!

Now I wonder what the diesel emissions of a 20 year old ford f350 are. A lot, I imagine.

Yes elva-1 is a Russian company, most likely they're trying to obfuscate that on their English language web presence. It is sort of a shame because they are just as competent as many of the Calif…

Not even recent, the US supported Mubarak since he took power after the Sadat assassination.

Though with small monopole and cellular rooftop sites, MW can frequently be built in a ring or redundant traffic path configuration. Fiber to many endpoint sites like a cell tower is frequently a star…

There is no way they're going to get millions of random clients and tourists to use 802.1x auth on their phones.

Though you need to be 500-650 meters max from your source of bandwidth for it to be reliable, 60 is super short range.

Sort of like when Pakistan's PTCL hijacked YouTube.

Real headline: Swiss ISP's upstream provider (a large backbone who should know better) fails to implement prefix filtering.

It'd have to be a big ass drone, I have links that stayed up when a Canada goose was sitting 2 ft directly in front of the 60cm antenna on one end.

It can have some effect but at the distances aimed (max 3km for a high reliability, high Tx power 80 GHz link) it doesn't affect much. A link that is a nominal -34 RSL on a clear sunny day might …

The key part in physics is it's still a wave... And a singlemode fiber is a type of waveguide. A 120GHz signal is a wave, a 171 THz signal is a wave, the latter just has a much shorter wavelengt…

signal/noise ratio is a big one and RSL level. There are even 4096QAM radios now but they need a signal like -51 to operate at their full modulation. Otherwise they ACM down to 1024 (around -62),…

Not really, 80 GHz is definitely difficult to aim, the very center of the beam is quite small. The mounts for the most popular antennas accommodate this and have very fine adjustments for the azimuth …

I've yet to see a product of any sort I can buy with a credit card or purchase order. Would also like to know if anything comes of it.
