He's been telling us all he knows about the NSA. Thanks to him, we know exactly more or less what they are up to. Every day, there's something new. Some things, we now know, they can do (shock horror, better watch our step). Other things, we've found out, they cannot do yet (so it's safeish for us for the moment to do these things with totalrelative peace of mind). It helps that the young man is able to leak to us PowerPoint presentations in which NSA operatives candidly inform one another about what they can and cannot do about this or that technology. These fall into our lap and we smirk, knowing that we've found part oftheir weakness.
Here in .nl Albert Heijn uses the exact same system, and on the occasions I've used it (my regular store doesn't have them yet) it worked smoothly. The running total on the scanner is a nice extra. Haven't had any exit checks yet.
BTW, you also have to scan your loyalty card to be able to take a scanner. And as far as that's a loyalty card: you just ask for one, handing over personal data is entirely optional.
If the Galileo works in a similar fashion and doesn't just emulate the Arduino in software, then it would be a great addition.
The GPIO pins are controlled via an I2C I/O expander, with the I2C bus running at standard speed (100kHz). So
a) there _is_ software inbetween what the sketch assumes is an I/O port and the actual hardware, and
b) bit-banging will only manage to get you a couple 100Hz at most. which is about 1000 times slower than you'd be able to achieve with a real Arduino.
Like the fact that you've lost your ability to have a green roof. That is to say that you couldn't create a green environment to capture and use the rain water to reduce the gray water run off which ends up going in to the sewer system.
Nonsense.
First: the rain that would fall on your roof, still falls on your panels (they don't magically stop precipitation), runs off them, onto the roof proper and into the rain gutter, from which it can be collected.
Second: if you have a flat or lightly sloped roof, it's still advantageous to put whatever it is you'd put on it underneath the panels. The roof stays cooler, increasing the panels' efficiency.
The answer was no as you need AC to run the inverter
Depends on the inverter. Ones that can run in 'island' mode don't necessarily need mains AC, although getting them synced when AC is restored may require a restart.
There's also the possibility of using an offline UPS (the type that basically runs off batteries that are kept topped up while there's AC), with a separate charging circuit grafted on that runs directly off your PV panels.
£1,200:£52 Looks like a much better ratio than you get for the supplies on ink jets.
And like inkjets, the price for the printer will fall, the price for consumables won't. Although the moment that a new printer with a set of cartridges will be cheaper than a replacement cartridge for last year's model may be some time off still.
Not the same as Propane.
And where did it say 'propane'? Sure, it's not the same as propene/propylene, but that's neither here nor there.
-ane : CnH(2n+2)
and for n>= 2
-ene: CnH(2n) <- one double C-C bond. Old nomenclature: -ylene
-yn: CnH(2n-2) <- one triple C-C bond
1572864/229376 = 6.857 bits per char, which sounds as close to 7 bits per char as makes no odds, which sounds fine to me.
You're calculating bytes per char, not char per bit.
229376 bytes would be 1835008 bits, if we're talking 8 bits per byte.
So 1572864 chars in 1835008 bits would be 0.857 char per bit.
Currently it's a solution looking for a problem that doesn't exist,
Sure, I could go about the house when I leave, or go to bed, to check if all the doors are closed and locked, all the lights are off except the ones I want on, etcetera, etcetera, or I could press a button that selects the desired state.
Now include a sunscreen that I want down because otherwise the house will be uncomfortably hot when I return, but which had better be retracted when the wind picks up. I also want ventilation and heating control to coordinate between them, and shut down a room's radiators when there's a window open.
Next step: running stuff that can run either on low nightly tariff, or on solar when sufficiently available.
If you think those are non-existent problems, you're wrong.
On my bookshelf there's a book by a guy (currently the book's in one of at least a dozen boxes due to a move, and I can't readily recall his name) who wrote reviews for a British motorcycle mag in the 1960's and 1970's. 25 years on he decided not just to bundle some of his articles in a 'best of' compilation, but to go and visit the designers of those machines, and interview them on the background of their design choices back then.
Very interesting indeed.
I was going to say the same; the most frequent refrain after "lend us your calculator" was "where's the equals button?"
One particularly obnoxious and ignorant twit, whose sense of entitlement apparently extended to me supplying him with a calculator, took about five minutes of key-pounding (this was an HP29; it could take the abuse) before latching on to the lack of the equals key. He then demanded "a normal calculator".
"Here, have my slide rule".
One small error: the EL3300 and its direct successors used five C cells, not AA; those wouldn't have lasted a C90. I know from experience. Lacking fresh C cells and a working mains adapter, I bodged five penlites in the battery compartment of my EL3302 using oodles of sellotape. It was hardly worth the effort.
"We have concerns with the [possible] changes, such as requiring the maintenance of data in Brazil," said Bruno Magrani, head of public policy at Facebook Brazil, according to the report. "This requirement would entail huge costs and inefficiencies in online business in the country, it will impact small and new US technology companies that want to provide services to Brazilians."
Companies providing service to Brazilians would quite likely be located in Brazil themselves, and thus be unaffected. Just stops them from using a foreign cloud provider, but I suspect there will be sufficient local supply to satisfy that demand. For foreign companies that would be the cost of doing business in Brazil, just like it is in Switzerland.
There was an article recently about a slot design that would make magstripe skimming a lot harder. The card would be inserted broadside, so that the stripe doesn't pass lengthwise over a single point in the slot, then rotated once fully inside the machine.
Of course, rotating would only be necessary if the ATM needed to read the magstripe in the first place, otherwise it's just additional mechanics that can fold, spindle and mutilate your card. Having a read head that moves on a spindle is a long-solved problem problem anyway, so that's a more suitable solution for reading the stripe.
As for protecting the keypad against overlays, maybe have a close-fitting cover over it that slides off after you've inserted your card?
For a gun, some parts such as the barrel you want to print in a single piece, to give them as much structural integrity as possible. Else you'll be futzing around with epoxy resin and acetone, to get the pieces to become one and you'll be cursing why you didn't build it from glass- or carbon-fiber reinforced epoxy in the first place.
The internet can help people conduct and grow their businesses in remote areas (ie: they can reach foreign markets, investors etc), thereby bringing prosperity to remote areas help improve the quality of life, and incidentally give them more money to spend on healthcare and education.
And infrastructure to actually get their products to or from remote markets would magically appear when there's internet?
There are ways to help these people help themselves. Internet access is not the first on that list. By far.
"We have a situation where 1.4 billion people in the world are overweight and obese, and at the same time one billion people worldwide go to bed hungry,"
That's 1.4 fattie per, should not only solve the malnourishment problems, but also, as a side effect, reduce use of natural resources such as petrol, textile fibres and large cars
The noisiest was a 600lpm drum printer (long since retired) when printing a 132 character line of the same character.
Well, you get a rather distinctive sound when printing a line of the same characters, but if you want LOUD, then figure out the character pattern that makes all the hammers fire at once.
(the one with the ear protectors instead of the glasses)
you put it into a ruck sack, tank bag, etc. then you are not holding it,
This is about getting a burger or something from a McD's Drive-through. Whether you move away from the window holding the bag in your hand, between your teeth or jammed between your arse and the saddle is not the point, but apparently some people want to assume you can only do the first, and base their condemnation of one's action on that assumption, considering it unsafe (which it's not).
Never been stuck behind a cyclist for miles on the way home after a long day? Never been hit by them, and / or nearly hit by them?
And this is relevant regarding what happens in a McD's drive-through, where things proceed at a pace not faster than the capability of the burger-flippers to hand out their wares to the consumers in the driveway, exactly how?
