If you don't mind me asking, what carrier, which version of the S4 mini, and what ROM did you use?
I have an S4 mini, CDMA/LTE version, on Sprint, so this interests me. The battery life is not currently bad, but it would be interesting to de-bloat the firmware.
Just exactly how do they propose 'taking out' a drone?
There is at least one case where a drone was taken out by a fire hose at a house fire. The troubling thing in that case, though, is that a firefighter took his hose off of the fire to take out a drone that was far enough away as not to be causing any real problem. The fire department ended up replacing the drone.
Part 15 reads almost the same for 900 MHz as for 2.4 GHz: You can use 1W if you are doing one of three things.
Thing 1 is to send a direct-sequenced spread spectrum signal (not in this case)
Thing 2 is to send a frequency-hopping spread spectrum signal, with a maximum dwell time of 400ms and a minimum of 50 channels in your spreading sequence (again, not the case here)
Thing 3 is to send a digital signal of at least 500 kHz RF bandwidth (which is likely to be the case here)
Additionally, there are bonuses for using good antennas (the FCC seems to want to encourage this). You do need to reduce your transmit power if you have a gainful antenna, but you only have to reduce power by 1dB for every 3dBi of antenna gain. For example, using a 3dBi antenna (for instance, a 5/8 wave) would double the strength of your transmitted signal, but would require you to turn down your transmitter power by 1 dB, making it roughly 800 mW rather than 1W. Put this together, and you get an effective radiated power (ERP) of ~ 1.6W.
In a more extreme case, imagine using a 24dBi directional antenna: You get a 2^8 boost in your signal from the antenna, and only have to cut your power by 8dB. Actual transmitter power ends up at 160mW, but the boost from the antenna gives you an ERP of ~40W.
From the CLI, a directory appears to be just another executable object. Name it on the command line and you are there. Put another way, the "cd" command is just white noise.
Device names, volume names and aliases are interchangeable. Program or script needs a particular volume of removable media? Simply reference it by name (e.g. foo:). A dialogue box will pop up asking you to put that volume into any drive and click OK. You never need to click OK, because it will detect the volume insertion and carry on. Did you copy that data to the hard drive? Just define an alias so that, for instance, foo: now points to system:volumes/foo.
That said, don't look to Amiga as a model of stability . . . it wasn't. All it took to bring one to a red guru meditation was to attempt to read past EOF.
It wasn't really his guitar cables that were under discussion at the moment . . . he was going on about the expensive audiophile cables he'd put into his home system.
As for his guitar cable, as long as the 1/4" stays seated and the current flows, it's all good. The hum itself was in his amp, which was a bit vintage. Now, vintage guitar amps are fine as long as they are maintained, but this one needed some help. I know another guitarist that uses the same amp and it sounds great.
customers who advocate the superiority of your product on faith alone. Because they spent so goddamn much.
The guitarist in a band I've engineered for is stone deaf but thinks of himself as an audiophile. He can't hear the hum coming out of his guitar amp, but swears by these overpriced interconnect cables as well as the special acoustic pad that he puts said humming amp on. One night I pointed out one of the XLR cables to him and said, "You see that $10 cable there? Whatever you're listening to went through one of those." He didn't say another word to me all night.
That's very true, but it is an interesting question.
Now, the further question that comes to mind is whether or not some circumstances might invalidate the passport. Is it still valid if the software is patched (probably)? What if it is upgraded to the next major rev (a bit fuzzier)? How about if the software is erased and replaced (maybe the does the equivalent of installing Linux)? What if the hardware get accessorized or customized? What if parts are salvaged from two different robots to build a third, essentially different one? Etc.
None of these things are out of the realm of the likely. A robot is just a mobile computer with the ability to move something. All of these things that the tech-savvy do to their computers, so . . . why wouldn't these things be done to a robot?
How will a gun help you with NSA spying again? Are you planning on blowing your own brains out? Because that surely solves the problem. More than one problem, in fact.
You are making the mistake of assuming (a) that the AC was describing a rational actor and (b) that the AC is this actor. I would not be surprised to find that gun sales have gone up, and it has nothing to do with whether or not it will solve this problem or any other. I believe that if there was or is such an uptick, it would be at least partially have been triggered by the NSA's domestic spying.
I believe it may also be somewhat impacted by the type of building. What I have seen is in industrial buildings, office buildings and malls. I have seen the 208/120 wiring you described.
One particular building where I used to work had 208/120 in the data centre, but most of the building's lighting was 277. 277 was also available in the data centre, as was 100 and 240, because we were frequently hosting our customer's computers, which came from all over the world. I don't think I ever saw the 277 used, but the 240 and 100 were provided by small single-phase transformers in a side-room.
As it currently stands, commercial buildings often have 277V lighting circuits (this is in the US) because it involves installing less copper in the ceilings.
From this, one can intuit that lowering the voltage will significantly increase the amount of copper, but let's take an example and make it more solid.
Let's say, for the sake of example, that we were considering 48V DC as an alternative to 120V AC (I personally would not want to consider anything lower than 48V in a home environment). If you need to deliver 1200W from point A to point B, it will require 10A at 120V, and 25A at 48V.
That 10A could be safely delivered on a 14 ga. wire in most domestic contexts, but will probably be delivered on 12 ga. For 25A, however, you're going to need 10 ga.*
A 250' roll of wire is ~$43 for 14 ga, $95 for 12 ga., and $138 for 10 ga. See the problem?
For the next challenge, you will also need to use different, more expensive switches and circuit breakers, or drop back to using fuses. This is because an AC arc self-quenches in half a cycle or less, and won't re-establish until the contacts are brought close enough together. The DC arc, on the other hand, is continuous, and requires additional effort to quench. Just for the record, there is an arc every time that a circuit breaker or switch is opened under load. This is the reason why you will often see switches and breakers labelled "AC Only".
Now, this is not to say that these problems won't be overcome or that a different variant might come about. Who knows? Maybe they'll gravitate towards 120V AC or some such, in which case it will be 1915** all over again.
(*For the non-Americans and uninitiated, US wire gauge is backwards: larger numbers are smaller wires. 14, 12 and 10 gauge are ~2.1, 3.3 and 5.3 mm^2, respectively)
(**There is nothing special about 1915, but I live in a house that was built in 1915 and was electified from day one. It would have had DC delivered to it in those early days, courtesy of Mr. Edison's various efforts in my current home town of Schenectady.)

Funny, I thought they were radio frequencies that are inserted between existing ones.
Mine too! It's amazing how they seemed to know that I was looking for my stuff. Even more amazing, it's more up-to-date than my backups!
Fuck it. I'm done with backups. Whoever runs this site is doing a much better job than I could ever do.
Regardless of that, an Atom N450 at 1.66 GHz is a pretty low-end machine, even for 2005.
Normally, one would use the word "prosecuted" here . . . but I like this version.

Well, tax, death, drive failure and tax hasn't got that much tax in it.
That doesn't necessarily follow, however, the drivers may be entitled to mileage.

Ooh! I wish I had mod points for that. I like it!
You need a new bank.
You know, I had mod points just a couple of days ago. What I wouldn't give for one right now. Kudos, sir!

This is true for Time-Warner also.

Yes, it is. I've known that for years. It's not the solar that's being claimed infeasible, it's the idea of wiring your house for low voltage DC.
Yeah, I don't think it's happening.
The heavier wire is to reduce the resistance, which reduces the voltage drop and the heat generated.
Ray Charles kind of did, too, with What'd I Say, but he kind of stood alone with that one. The Doors made it stick.
This is largely what I was thinking.
As it currently stands, commercial buildings often have 277V lighting circuits (this is in the US) because it involves installing less copper in the ceilings.
