FBI alert: Get these motherf'king hackers off this motherf'king plane

You just buy an optoisolator for a few cents. LED and detector in one 8-pin DIP package.

If you need E3 isolation for some reason (in a teapot), buy the bulkhead mounted version for $20.

bazza: "...generally rely on a single core of fibre optic to get a guaranteed one way flow of data (it's physically impossible to send any bytes, data or instructions back the other way)."

If you have an LED on one side, and a phototransistor on the other, with an air gap in between, then that in itself guarantees the 'diode' unidirectionality. Unless you think that phototransistors can emit light to be detected by the LED. So what's the fibre got to do with it?

Me thinks you are confused about the fibre bit. Some may include it if they want distance in the air gap.

There are bulkhead mounted LED/Phototransistor devices. Fibre-free.

The huge flaw in Moore’s Law? It's NOT a law after all

JeffyPoooh
Silver badge
Pint

Exponential

Well, number of transistors per unit area goes as the inverse square law of the process dimension. So even if the process dimension is only a linear function of time, the transistor count will be squared. If transistor count is linear, then obviously the process has be less than linear.

Moore's could be defined as: see Scaling Laws.

The obvious way forward is further into the third dimension. If the process can mature both thinner layers and a taller stack, you might get onto the squared growth curve.

The cheapest fix to keeping technology running smoothly would be to convince the coder drones to stop cobbling together bloated bugware. Fix that.

Obviously MS are not using enough glue in their hardware offerings...

Glue-seller Apple makes a tidy profit.

Ever since 8.1 came out, I've bought a small flood of windows gadgets. One commonality to all those purchases was rock bottom prices. $100 tablets (shocking not bad), $50 smartphone (nice), $190 laptop (sweet!), $60 Win OS for my son's gaming PC.

I'm happy that they've got their Mojo back. Android is pathetic next to Win 8.1 based gadgets. Still have the droid thingies, but I'll pick up the Win gadgets now.

The ONLY way to watch YouTube is...

The ONLY way to watch YouTube is on a device that enables one to install an Ad Blocker.

One of the big advantages of the latest crop of cheap and cheerful Windows 8.1 tablets and netbooks is that one can install an ad blocker very easily (ironically, even into Chrome, LOL). The fact that these Win 8.1 gadgets are being sold at giveaway prices in recent months is a bonus. Great gadgets for YouTube.

Frankly, Android is so last year. After watching my Nexus 7 grind to a halt due to the Google Is Stoopid bug, I'm getting low on goodwill for those Google asshat fackors.

Posted from an 8-inch $100 Win tablet. Not bad. Works well.

Makerbot axes 'scores of staff' – 3D printing just doesn't pay the bills

Re: F**k them and the horse they rode in on

"rent time"

Edd China of Wheeler Dealer printed off a pair of small plastic bits to hold LEDs in the brass headlights of a 1903 car.

IT TOOK 15 HOURS!!

There's a business... Rent the machine for $100 an hour, and surprise the client with a $1500 bill.

Somebody needs to make a video that alternates between a factory cranking out 20 plastic things a second, and a 3D printer slowly sweeping back and forth, back and forth, back and forth. Sound track would be somebody explaining how all mass manufacturing will be 3D Printer based "in five years".

Re: Business model

The parts of a 3D printer that can be 3D printed, plastic bits, amount to a tiny fraction of the total cost. At least they would be cheap if they were injection molded at 800 per hour, as opposed to slowly 3D printing them over a long weekend.

The other 95% (cost wise) cannot be 3D printed. Not now, and not for a hundred years.

Thank you for using the word "parts". Very precise. Too many BS headlines like "3D Printed Car", and too many dimwits actually thinking it's true.

Re: A very well done

You know that they sent near-Live video (certainly not HD) back from the fricken! Moon in fricken! 1969? Kids these days. Can't do this, can't do that. "It's difficult..." Bunch of pansies. ;-)

HD is optional. Any off-the-shelf drone with a video link. A nearby ship within LOS to the drone (20 miles is easily do-able), with an H.264 video encoder to crunch the stream down to 432 kbps, and an Inmarsat internet link (common on ships). $30/minute for air time. Done.

If you really want HD, then H.265 and drop the frame rate. Not worth the trade-off.

Other satellite links are more bother. Not worth it.

Nope. Just medium sized (700T), but one that can flip up on end.

Why a wobbly wave-tossed barge?

Why not put a platform on some chunk of stable land somewhere?

According to the promotional video (where everything works perfectly), the rockets are supposed to land near the spot from whence they left.

Obviously the landing spot will eventually be moved further afield after the first major failure when the authorities decide that aiming rockets back towards expensive launch installations is not a brilliant idea.

So Musk will need a barge to bring the rockets home, from the landing spot 100 miles away in some empty valley.

Re: Expand this to all technology

Patents are not the same thing as "plans" (tech data package). Older patents were often useful, but more recent patents are deliberately obtuse. They push the limits on the requirement that the description be sufficient to one skilled in the art.

By the way, patents and even applications are already in the public domain. Including any embedded "plans" LOL. The info is already in public domain (freely available, no cost, help yourself), just not the rights.

How does a drone knock on the door and get a signature?

Or will it simply drop your newest iThingy onto the front lawn and leave?

Anyone compared max range of such drones to the number of depots required? Maybe they could deploy the drones from a hovering mothership. Maybe they could simply put 3D printers on the Fusion Powered endlessly-hovering mothership, and simply 3D print your new iWatch in 15 seconds and drone-deliver it to you a minute after you ordered it. Maybe they could drone-deliver a new 3D printer and I won't need to buy anything from Amazon ever again. Except cartridges of 3D printer paste.

The HP Stream 7 tablet has electrical interference noise on the headphone audio. I sent the first one back, and bought another; same noise. Some sort of electrical interference.
