Book: Help Your Kids with Computer Coding
http://www.amazon.com/Help-You...
Got this for my nearly 8 year old and it's an awesome book to start the kids on. Starts them off with Scratch and moves them on to Python.
...if the developers of this app are secretly associated with an AD provider in order to generate more revenue from the companies paying them for the ads.
As a developer in the industry here I can honestly say nobody in our industry would be dumb enough to use this tool. Security is very important, and i'm sure PCI compliance would be a huge issue. Unless under a dual-control situation and 4-5 physical doors from the outside world, no un-masked CC# exists except on physical card.
Yes, it would be nice for that service for software developers to use as a tool for display....like in my case, to provide cleansed data to the screen without manually cleansing data....but the issue is that PCI will dictate where that data can exist, and if it's uncleansed and accessible to a DB admin or software dev, there's too much visibility. They look at it from the standpoint that if a single person has access by themselves then they're likely to steal them.
I don't see why they would automatically allow search within masked bytes (at least if it's ultra sensitive).....I can understand if maybe there's a setting like (sensitive to search) so that CC#'s couldn't be brute forced, however a search for a person's last name where all but the first letter are masked would probably be okay.
yeah, and a neural net can be programmed to handle the different gaits and learn to optimize while in the appropriate gait mode. I understand this would come at a cost (more computation and memory) but in today's world memory is so cheap and small. In that case you wouldn't have a 'damaged' gait, if damaged, upon usage of a gait the learning algorithm would adapt to each environment if necessary...
Think of the uphill gait while damaged...in your scenario you'd pick either 'uphill' or 'damaged'....but with the neural net it would adapt the uphill to perform best while damaged.
Having taken an AI class in College, I'm wondering if this might be a real-world scenario where a self-learning neural net would come in handy....not only for the broken leg scenario, but because you can tell it to learn, the "Gait" can be optimized at run-time under any scenario.
Now police can use the device to charge you with PCS (possession of a controlled substance) for detecting minute traces of a substance. Just what we needed.
Yeah, and many in the hard right will oppose it too because it's "playing god". What's your point? The reason liberals tend to oppose GM tends to be more along the lines of Monsanto screwing things up by:
1) Patenting a seed, and then patent trolling people who's fields were pollinated by their patented seed.
2) Adding in a resistance gene to a plant that didn't have it, using harsh chemicals to kill pests, where the plant soaks up the chemical and is then eaten by people.
3) Causing drug resistance (Roundup) to spread to plants that weren't meant to have it (by lack of proper testing), thereby causing destruction to farms where there are hardly any alternatives to nuking the field to destroy the weeds that are now resistant.
4) Where the use of the "Scientific Method" and independant testing is ignored in the name of profit.
Just like Google, Microsoft, Apple, etc, etc. Nobody wants to fess up, but some appear to be "trying" to step up to the NSA now.
I wonder if they (private companies) secretly allowed it(NSA infiltration) to happen under fear of the NSA using whatever power they have to get the companies shut down if they didn't follow suit. Now that the public has been informed, the companies are using all the plausible deniability they can to prevent lawsuits. In the case of the UPS, I don't think there's any plausible deniability to use...It's not a software system that the NSA could exploit per-se.
Or is it the case these companies really are just as corrupt as the NSA?
I really don't see any other alternative, unless you want to argue that Snowdens docs were fake (Highly unlikely).
nope....not what i'm talking about. I'm talking about how you can use less energy to power certain devices.
Take a traditional light bulb for example. 120V @0.5A using 60 watts. So in 1 hour you use.06kWh, and typical efficiency for a bulb is 15 lm/w so you get about 900 lumens from 60 watts. Because the standard connection runs at 60hz it just so happens that the 60 watt bulb typically means it uses 60 J/s.
Now lets take the resonant frequency of Tungsten (4.161mhz)....If we can pulse at this freqency, we can put less into the system and get the same observable output (lumens). Since the frequency will be increased by 69.35 the VoltAmps will need to decrease by the same factor to use the same power. So say 4.3V @ 200mA is a good approximation. Now because 4.161mhz is the resonant frequency the efficiency of the transfer of electricity to lumens has increased, we can likely decrease the voltage and/or current quite a bit.
So lets say that now the efficiency of the light bulb goes up to 30lm/w at the resonant frequency...
we would now be able to use the formula (V*A * 69.35 = W -> W*30 = lm). This would give you 1739 lm at that 4.3V@200mA, so you'd need to decrease significantly. Lets take 2V @ 200mA, you'd get 27.74W @ 4.161mhz frequency, that gives you a lumen output of 832lm.
Now you're using only 27.74 Watts per hour to provide approximately the same amount of light. Of course in the real world the numbers are a bit different, but that's how it can be calculated.
I was in a bit of a hurry to finish up, sorry for the sloppy math.
What electronics manufacturers really need to focus on is boosting energy efficiency by using harmonics. Using 60hz for nearly everything is very inefficient. There are various YT videos showing efficiency gains (although some like to call it over-unity/free energy when it's not) by matching the input frequency to the harmonics of the devices (light bulbs for example).
That's a great quote btw. I was going to suggest a similar issue with the so-called sea level rise from melting ice (if the ice is floating and melts then it doesn't raise the level since ice has more spacial volume than water per)...however there is also suggestion (from the global warming/science community) that some of the ice melt from Antarctica is from ice that is over land and not currently floating or below the sea level, which would, all other variables excluded, raise the sea level.
Not trolling....My logic is that if the continent rises, then the volume of water it displaces would in-effect decrease, thereby countering the effect of the water rise. The real idea i was putting forth was that they could measure the volume displacement countered to see what the offset really is. 15mm/yr rise doesn't sound significant, but if you consider the area affected, 15mm could make a huge difference in offsetting the purported rise in sea level.
http://www.science20.com/news_...
Apparently the loss of ice in the Antarctic is raising the continent as well. If this is true, how much will the levels really rise as the ice melts? Scientists, I believe are a bit too quick to assume melting ice caps are going to flood several parts of the earth, and likely being pushed to by the global warming crowd to push their BS agendas.
Even though I haven't yet tinkered with an Arduino I have to totally agree with this. As a professional programmer with similar experience here are a few reasons why:
1)I have had to work with machine automation in both of my programming jobs extensively. Knowing how to program 'realtime' devices is very useful in an industrial environment (Reading barcode readers, processing, output....or reading relay state/change, determining course of action, switching relay or sending notifications to a user...or combinations thereof like reading from a barcode reader and comparing to a database/list/group and sending a relay output to tell a belt to stop for example).
2)You will learn about many things that are difficult to reproduce without sensors/switches/etc including timing, triggers, events, etc
One issue I do have with this however is that sometimes dealing with devices like this, you can easily fall into a trap where inexperience can lead to code that is almost impossible to debug or problems that come up that are very difficult to reproduce.
That equation is assuming PV cells are being used in the orbital station...if you RTA, they appear to want to collect light, and direct it towards earth to a ground-based generator that will convert the light into electricity.
The technicality I was speaking of was the anonymous 911 tip allowing the stop in the first place, regardless of the fact that the police witnessed no suspicion themselves when tailing him for 5 minutes.
As to the inference that the truck's driver was drunk, Scalia pointed out that the police officers here followed the pickup for over five minutes — and "five minutes is a long time" — without any indication of drunken driving or even bad driving.
"After today's opinion," said Scalia, "all of us on the road, and not just drug dealers, are at risk... "
Actually sounds Scalia was the dissenting opinion, period. I tend to agree with the quoted point of view of Scalia...an anonymous 911 call prompts police to target this driver, the driver gives NO indication of dui/reckless/endangering driving, yet the cops STILL pull the guy over, and win in court because of a "technicality". Scalia is right, we are all at risk for abuse of power by cops (not only that, but the justice system ruling in favor of the loss of our freedoms that are OWED to us by the Constitution).
I would also think that Microsoft could come out with a fix to the software that would store that key that's accessible/decrypted by the PC Admin's/User's password via a utility (but not writable by other programs) in order to "recover" files where the key has been lost/'stolen'/etc. This would only work of course IF the hackers were using the local copy of the encryption DLL and not a downloaded/hacked copy (if it would even work that way).
Wouldn't it just make more sense that the trades be kept secret, using encryption until the transaction is completed?
Transactions like this should prevent someone else stepping into front of line. Because this is basically what's happening, is that these machines are taking advantage of a security flaw that allows them to see a transaction before it's complete,
It would be similar to going to a grocery store where you're ready to pay and someone behind you hands the cash to the cashier before you can get your money out and takes your stuff. That kind of behavior certainly wouldn't be tolerated at a grocery store (they'd definitely get punched in the face!), and shouldn't be tolerated on the stock market.
The delay really wouldn't work....it would only take 5 seconds longer for you to find out you've been had, which means they're now stealing your time too. Any moderately useful encryption where public/private keys are used, like PGP, for any transaction prior to being completed would fix this.

Need I say more?

Sorry, to clarify what I mean is oscillating at the resonant frequency of the device.

There are various YT videos showing efficiency gains (although some like to call it over-unity/free energy when it's not) by matching the input frequency to the harmonics of the devices (light bulbs for example).
It's more logical that the theory that the planes took the towers down all by them selves...and that fires alone took down building 5.
Don't forget the packs of rabid dogs....I can imagine seeking them out to study while brainstorming the next #1 best selling zombie game.

Oops my bad...i should have RTFA...i saw the pic and thought they'd be reflecting light....this idea probably wouldn't work....wow
