Hell hath no fury like a radar engineer scorned


Re: Can this inform the 5G debate?

Not a radar tech., but spent ages on the lab bench designing microwave stuff, everywhere from C-Band to J-Band. Open waveguide? Of course. However, I have no daughters, but my 3 sons were conceived during that time, so that one doesn't hold water. Still got good eyesight, too.

As for a mere 200 mW peak setting off flash cubes - garn, don't believe it!

CIMON says: Say hello to your new AI pal-bot, space station 'nauts


I thought it looked more like Holly from Red Dwarf.

Great time to shift bytes: International bandwidth prices are in free fall


Re: "...as many different wavelengths as you like..."

Weell, it is true that the erbium-doped fibre amplifiers used in modern-day repeaters restrict the bandwidth (in its original sense), but it's rather wide, typically covering 1530-1565 nm for a C-band system - that's enough to shift 10 Tb/s (10 x 100 Gb/s channels) or more across oceanic distances with modern modulation techniques.

Driverless cars will lead to data-sharing – of the electrical kind


Re: First create the infrastructure for taxes

It's been done long since in New Zealand: all diesel vehicles used on the public highway have to display a Road User Charges sticker, paid for in advance (basically so farmers wouldn't pay fuel tax for their diesel tractors). Trucks pay more than light vehicles. Electric vehicles should also have to pay, but are exempt until 2020 to encourage their uptake (they have the advantage here that they basically run on a mix of wind, water and geothermal energy - very "green").

Biker nerfed by robo Chevy in San Francisco now lobs sueball at GM


From the New Zealand Road Code:

"You can only pass on the left when:

"there are two or more lanes on your side of the centre line and you are able to pass safely by using the left-hand lane

"you are directed to by a police officer

"the vehicle you are passing:

"has stopped, or

"is signalling a right turn, or

"is turning right."

So, "undertaking" on a motorway is legal in drive-on-the-left NZ (but they are thinking of stopping that).

Japanese quadcopter makes overworked employees clock out


Re: when you like what you do...

All true, but there actually is a reward of sorts - or more to the point, an inducement. Most Japanese companies pay a "bonus" twice a year. Bonus? Well, each payment is typically worth 2 months' salary! That's the standard. However, the bosses can pay out a "plus alpha", and that is determined to a large extent by how long the victim, er, employee, has spent hanging around the workplace over and above the usual "diligent" hours.

There's another question about the drone thing. People feel they can't go home until the manager does - and the manager won't go until they do. (Positive feedback anyone?) So, will the drone dispatch the manager too?

I'd love this to succeed. "Karoushi" (death by overwork) is far too common in Japan, and of course social disruption is, as pointed out, even more common. Those are two birds that really need to be dispatched by one stone, or drone.

Who's to blame for the NBN? Hardly anyone remembers, or cares


Sitting here in NZ & ROTFLMAO

Just upgraded from a "paltry" 50 Mbps to 200 Mbps, and I'm not even on fibre (could get fibre, though, if I changed ISPs, but on GPON it wouldn't be any faster).

Australia commits to establish space agency with no budget, plan, name, deadline …


Re: Space port

Too late Oz, we've already got one over here in Aotearoa - it's called Mahia. It has needed no government input other than permission to launch (out over the South Pacific, no-one's head to land on, and no planes to worry about, so very few restrictions). It's all been done by our very own Kiwi Rocket Man, one Peter Beck. His RocketLab is about to launch its second rocket, with actual, real payloads on board. Now there's confidence for you - all they have to do is get the support company to remember to turn on the forward error correction on the telemetry receiver, and you can be sure this time they will. So put that in your didgeridoo and smoke it!

Achtung! German election tabulation software 'insecure'


Re: Just a sec

We have a general election in New Zealand on 23rd September. It's all paper ballots stuffed into ballot-boxes the old-fashioned way. No buggy software. There are suggestions that we should go electronic to rope in those potential voters who can't move more than their thumbs. However, there's a lot of resistance on the grounds that electronic voting is insecure/hackable etc etc. I'll put my by now geriatric hand up to join the resistance.

Swedish school pumps up volume to ease toilet trauma


Old Hat (Fart?)

Sorry Sweden, but Japanese public toilets have provided this facility for decades.

Happy 50th birthday, optical fibres for telecoms


Re: Institution of Electrical Engineers

Quite possibly here, despite being within cooee of Wellington (NZ). Well, I'm semi-retired now and not relying on being C.Eng for continuing work, so if it happens it happens. It would be a pity though.

Brit chip biz ARM legs it to Softbank for $32bn


Re: Once ARM becomes a Japanese company..

Japanese? Masayoshi Son (SoftBank-san) may be a Japanese citizen (even born there), but everyone there knows he's an ethnic Korean. Who are one of the biggest ARM chip makers? Samsung - Korean.

Sounds more like a Korean takeover to me.

Either way, it's a pity to see it ceasing to be British.
