It's a pretty annoying oversight that the rpi board doesn't have any holes for mounting screws, so you'd hope that an add-on plate like this might correct that oversight.
Yep Arduino has similar issues. While it has mounting holes, they didn't use proper keep-outs around them. One hole has a connector so close the threads of a screw would touch it - the screw head has no hope. Other holes have parts too close, but not as bad. All the holes are too close to the edge of the board. Also, the LEDs are in the middle, so they are not visible with shields attached. This is inexcusable for Arduino where there is ample unused board space. Other issues too, but I digress. The PI apparently suffers from the same lack of consideration.
That said, I do look forward to the day someone gets this concept right.
It is as if you have seemingly random data, and then Victor hands you an extra piece of decoding information, "Use photons 1, 3, 7, 8, 11,...". When you include only those in the set, you find the results expected.
That doesn't seem to be a complete answer. Those photons would appear correlated without Victors information. They would appear to be random, but if Victor turned on/off entanglement every 10 photons, we would see batches of 10 correlated photons or 10 random sets. I think in addition to enabling entanglement he also took measurements of the photons, and this information is needed by Alice and Bob. So I'm still confused.
The future does not change the past. But, information from the future can change what information we can extract from the past.
Thanks for the clarification. So then what's the point of the experiment? What information from the past becomes available when Victors data is added to the set?
I know I'm not going to let go of this assumption until there is some very, very convincing evidence.
Agreed. In my life, there has been a lot of odd things happening lately and this experiment fits right in. I certainly want it verified, but my tendency to immediately call "bullshit" on something like this is way down from where it used to be.
If Alice and Bob are the same person looking at the rate of correlation between the 2 streams of photons, Victor will be able to transmit a message *backwards in time* to them by deciding to entangle or not. If this is not the point, then there isn't a point to the experiment at all.
As I recall, the geologists in California can tell you the trajectory of such things. I remember a story (in Aviation Week maybe) more than a decade ago where they tracked a "wave" traveling around mach X (I don't recall the mach number but between 3 and 6) coming in off the coast and heading out to Nevada. Think conical shock wave from an aircraft. The speculated that it was a new secret plane. Oddly, this event also sounds like it was heading toward Nevada but much louder. So anyway, if they want to see where it went, check with the geologists - they've tracked quieter things.
...that this would affect a lot more than just Apple if upheld.
Yep, it would affect an industrial PC I used circa 1996 with a touch-screen to emulate a mouse. Yep, some things could be dragged around in a standard windows app with that setup. Hmmm I guess touch screens have been infringing this for a while now.
However I'm pretty sure that they needed a lot of help making them because creating these things require college level electrical engineering knowledge
The amount of help varies from team to team, but you'd be absolutely amazed at what kids can design in CAD these days. There are also some good programmers out there. The electronics isn't that hard with the fancy controllers provided in the kit. They provide some big motors and PWM drives that are easily connected to the controller - where the software lives. For autonomous play software is key. For RC play, the software will generally pass control inputs from the radio to the actuators, but there is often opportunity to add some PIDs to aid stability or otherwise customize the control. One year we had a camera that could give coordinates of a colored light over the goal - this allowed an automatic tracker to be implemented even in remote control mode so you could throw balls at any time.
I mentored a team in Michigan, and there are some that get professional engineering done by sponsors. But on our team the kids did most of the design, most of the construction, and all of the software. Some custom fabrication was done by sponsors, but not design or assembly. The adults were there to make suggestions and do things that were beyond the kids abilities - but a good mentor will have the kids take a crack at it first. We managed to get to nationals with a mostly kid-driven effort, and Michigan is the toughest state to get through regionals.
you either don't know what 'Dark Matter' means, or you don't know what 'nonsense means'...or both.
Dark matter is some as yet unobserved (directly) stuff thought to interact with ordinary matter in some as-yet unexplained way. It's influence is gravitational, yet it is not influenced by "regular" matter in the same way because it is magically postulated to exist in a spherical halo around galaxies rather than have a distribution similar to all the visible matter. It's existence is required to explain phenomena like why galactic rotation curves don't follow Keplers laws - which is redundant because they shouldn't.
So yes, I know what Dark Matter "is" and I know what nonsense is. They are one and the same.
So what makes anyone think stars in a galaxy should orbit according to Keplers laws? They assume a 2-body system. In the case of planetary orbits, we neglect the other planets and just consider 1 planet and the sun and Kepler works very well. How exactly is this supposed to work with a galaxy? If you show the reasoning, I'll point out the flaw.
One of the foundations of this Dark Matter nonsense is the Galaxy Rotation Curves that don't match "predictions". Wikipedia says the expected curve is based on Keplers laws - which don't apply to galaxies. I can think of a number of errors one could make which might lead to thinking Kepler applies, and in fact I believe that's what has happened....
All taxpayers should have access to it, even if they want to make money from it. It should automatically be public domain.
Actually, that would be "All taxpayers in that county should have access to it..." since they paid for it. Yet they are considering going quite a bit beyond that group.
What is it with this fear that someone will make a buck?
Yes, this puzzled me. It's like the BSD vs GPL arguments, but it's odd to me that folks in government are thinking like this. While I support the position, I would not have expected it from them.
If you had your kids vaccinated before they were able to discuss it with you, you believe in forcing people to take shots.
Wow stupid AC. If you believe in feeding your children, then you must believe in forcing people to do things. Parents make tons of decisions on behalf of their children, this is different than the state or other parents making them.
GIMP 2.10’s core will be 100% ported to GEGL, and all of the legacy pixel fiddling API for plug-ins is going to be deprecated.
This should be the only objective for 2.10 other than bug-fixing the single window interface which debuts in 2.8. They should get feedback on the UI, tweak a few things (not rework them) go full GEGL and get 2.10 out the door ASAP. The 2.8 is going to get a lot of people to look at it again, but when the features of GEGL are found to be missing they'll walk away AGAIN and it will be some time before they check in again. So let's not advertise 2.8 so much, but hurry with 2.10 and then make a push for people to switch.
There is no such thing is the "collapse" of the wavefunction. The observer just gets entangled with the experiment.
Yep. Notice that physicists can not tell the difference between a particle with a "collapsed" wave function and an "uncollapsed" one. If they could tell the difference, then streams of entangled photons or particles going in opposite directions could be used for faster-than-light communication. The guy at one end either "observes" his photons or lets them pass by. The guy at the other end reads the "collapsedness" of his particle stream and can now receive a signal. But alas, there is no difference in a particle whose wavefunction has collapsed and one that hasn't.
That's a "capacitor module" with "balancing" which means it's really a bunch of individual capacitors. Also, I said people think you can use both, but this is not the case. By connecting a capacitor in parallel with a battery you prevent the cap voltage from changing rapidly which it needs to do in order to provide that short-term high power. ( E = 1/2 * C * V * V ). No voltage change means no energy change. This battery/cap combination is a myth.
I was discussing MS with someone several years back, and he said "just the fact that we are having this discussion indicates there is a problem." This is so true. But don't treat the word "indicates" as gospel - it's just a strong indicator, not the last word. The more often you get these indications, the more seriously you need to take them.
Unreasonable expectations are most likely based on the fact you can't drive a hybrid like a traditional car and still expect to get more than minor gas savings. Even then, I mostly see hybrids advertised as 35-45mpg... not a significant improvement over traditional cars of similar size.
Compare the city mileage, not the highway. Also, use actual numbers for actual vehicles you would consider buying.

If Alice and Bob are in the same place, Victor can send messages back in time.

And fixed IP addresses where we send email peer-to-peer. Of course it still goes through the ISP, but it's not deliberately stored on their server...

Is guano produced by others or is "penguin guano" redundant?
