    Or you could make the comm package an unfolding self-guided glider plane. Balloon pops, packages senses it, unfolds, glides back to nearest assigned pick-up point using GPS.

    Realistically, you'll need a team of engineers for a couple of years to develop this so that it's reliable. With the risk of the cost of such a project spiralling out of control as unanticipated problems arise. And the lost opportunity of delaying deployment a couple to several years.

    Or you could have one employee with a pick-up truck assigned to retrieve the daily balloon. Even if most of the balloons fall in inaccessible areas, at several hundred dollars each that's still not much more than the cost of a couple of employees. The main thing I'd be concerned with is whether the balloons are biodegradable.

    I suppose such a project could be background R&D as the company grows, but even so the payback could be very long.

    I found out later that my hunch was correct - it's just unlikely for two photons to hit an atom at exactly the same (to within a plancks time) with a low powered laser.

    A Planck time (10^-43 s)? How do you conclude that number?

    If you shine two beams so that they cross paths, some photons will collide with each other and scatter.

    The actual mechanism, I believe, is that a photon can momentarily fluctuate into a charged fermion/antifermion pair, and the cross-beam interacts with those particles.

    My town has local buses - heavily subsidized by the mostly upscale taxpayers, who keep voting in the system because it's "public transportation" and therefore "green" - that run mostly or completely empty most of the day, going around and around town in useless trips that do nothing but waste fuel. In spite of that, a trip from one side of town to the other (5 minutes by car) can take almost an hour due to the convoluted routes and waiting for bus transfers in the center. I would guess that offering free taxi service during non-rush hours might even save the town money.

    Overall, the problem of efficient public transportation in a suburban area is not an easy one to solve.

    I wonder if any place has tried an "on-demand" bus system. Basically, on-line you enter your source, destination, and time window, and their computer figures out the optimal routes - which could be optimized in different ways, say to maximize passengers per mile or to minimize passenger inconvenience, whatever is considered most important. Then, for example, a bus could pick you up at your front door - pretty close to a specific time they tell you - and drop you off at your destination, after a few digressions along the way to process other passengers.

    Instead, virtually all laptops with touchpads have the mouse buttons below the touchpad, making it very awkward and error prone (like accidentally hitting the touchpad itself) if I try to stretch my thumb down to press them, unless my hand leaves the keyboard thus interrupting my flow.

    Does anyone know the justification for mouse buttons under the touchpad? I cannot think of any benefit at all. Even a regular mouse (that the touchpad is presumably imitating) usually has the buttons near the top.

    My favorite computer years ago (early 90s) was a Mac Powerbook with the mouse switch above the trackball and just below the space bar. I worked very efficiently with that arrangement, mixing typing and mouse movements seamlessly, and miss it. (Unfortunately I no longer have a Mac laptop and don't know how today's touchpads are arranged. Educate me.)

    It does seem that the Thinkpad with pointing stick/touchpad combo has a second set of mouse buttons under the space bar, looking at photos. Something to consider for my next laptop purchase. But they still have a second set of mouse buttons below the touchpad - why? It seems a waste.

    I am myopic and wear bifocals.

Ironically, I prefer the myopia: without glasses, I can do fine, up-close work far better than most people.

    In this instance, it's not really Netflix's fault. ... The reason they haven't is because the MPAA studios which supply the movies that Netflix's rents won't license them movies unless they use some form of DRM that they approve of.

    Well, if DRM is required, I don't understand why Netflix wouldn't simply provide a refreshed DRM copy to people who encounter a problem with changed monitors or whatever, rather than wasting customer's time and Netflix's money with customer support, suggesting switching to VGA, or telling customers they're out of luck.

    Since a refreshed DRM copy doesn't cost them anything, pissing off customers and probably losing a lot of them would seem far less cost-effective in the long run, than taking draconian measures to prevent an occasional "cheater" (who probably wouldn't pay for a 2nd copy anyway if these draconian measures defeat them).

  12. "Commercial Use" ill-defined? on Creative Commons Launches CC+ License · · Score: 3, Interesting
    One problem I have with this and other "non-commercial" CC licenses is that "non-commercial" doesn't seem, to me, to be clearly defined. Certainly there can be blatant commercial uses that are easy to identify, but there are many situations where it is not so clear. Suppose, for example, the material is posted a personal home page, which is provided free by the ISP in exchange for advertisements. Does that constitute "commercial use"? Clearly, the ISP is profiting from the material if it is drawing people to that page and thus the ads. Who owes who what money?

    Is a Red Cross advertisement commercial or noncommercial? If the Red Cross paid a magazine for an ad containing a CC+ licensed image, then the magazine is earning some money from it, even though the Red Cross itself is non-commercial. (Or is it?)

    It is even hard to come up with examples where the use is disconnected from the slightest taint of a direct or indirect commercial connection.

    Of course, CC+ is also incompatible with GPL-licensed software. For example, a CC licensed "non-commercial use" icon in a software package would prevent a commercial entity from using it, defeating the purpose of the GPL.

    I think the topic under discussion is romantic/sexual love, which has nothing to do with most things you mention. Well, maybe a video game character for some people - perhaps if they are lonely and can't find a real life lover - although that is strange and probably involves imagining the character as having sexual attributes of a real person in some way.

    I agree that individual television signals will almost certainly be too weak to be decoded into the I Love Lucy program.

    However, there is another type of information being transmitted - the fact that there is a transmission at all. Someone else will have to calculate the numbers involved, but I would guess that the existence of TV signals (not as TV per se, but just as relatively narrowband frequencies) could be detected vastly further away if they were integrated over a period of say years or decades.

    What the alien would see would be a spectrum of oddly but precisely spaced average frequencies (based on FCC / other gov't channel allocation) that didn't correspond any known natural process, and the alien might conclude that the signals are most likely artificially generated. Perhaps even the average bandwidth could be inferred in some cases, giving a rough indication of the information rate of the modulation, if they suspect the signals are used for communication.

Well, unless you encrypt EVERYTHING I guess.

    But even the effort of creating a one-time email address just for them (forwarded to your real one), if your are this paranoid, would seem preferable to allowing them to inject their data into your TCP streams.

    And the injection wouldn't work anyway if, being as paranoid as you are, you only allow anonymized proxied https pages onto your browser. So just how, exactly, would you expect them to communicate with you?

  18. My iTunes story on RIAA Argues That MP3s From CDs Are Unauthorized · · Score: 1

    Audible (the online audiobook seller) has an option in it's playback program 'rip to cd using Nero'. That wouldn't survive in a stricter copying environment.

    Several years ago I bought an audio book from the iTunes store and needed an mp3 version to listen to on a trip. (I don't have an iPod.) iTunes would not let me create an MP3 because it was DRM'ed i.e. an iTunes store purchase. I actually didn't know that the convert to MP3 feature was disabled for DRM'ed audio, and their cryptic error message took half a dozen customer service emails (most of which were idiotic canned responses having nothing to do with the problem), when they finally pinned this down and pointed me to a web page saying this.

    I also couldn't burn it to CD, then convert it to mp3, because (at least at the time) iTunes would not burn it to CD because it wouldn't fit on a CD.

    At this point I asked for a refund, and they refused. At one point I became so heated in my emails that they interpreted it as a legal threat, and suggested that all further communications should go through their legal dept. - which couldn't be contacted directly, but only through a lawyer who I would have to hire.

    Finally, after digging through their site, I found an old web page that advertised the MP3 conversion feature without mentioning any special restriction on iTunes store purchases. This was a mistake on their part, but nonetheless it could very clearly be interpreted as fraudulent advertising.

    After a few more emails debating this web page, they finally relented and refunded my money, telling me this was a one-time thing that they would never do again.

    Frankly, the time and emotional energy I spent on this far exceeded the money I was refunded. Anyway that is my story, and it is the reason I no longer buy from the iTunes store.

    P.S. at that time Jazz (I think it was called) could defeat the DRM. But by the time I found that out I had already invested so much time with customer service that it became the principle of the thing. By the end of this debacle I developed an active dislike for the book, and anyway the trip I wanted it for had come and gone, so I just deleted it per their instructions, after my refund.

  19. Re:SAGE is an interesting project on Open Source 'Sage' Takes Aim at High End Math Software · · Score: 3, Interesting

    It may be argued that computers are not really an appropriate tool when truly "correct" mathematics must be relied upon. My response to that is that as problems of interest become ever more complex, limitations both of the human mind and the human life span will ultimately limit the problems we can solve unaided. The task for us now is to create a system we CAN trust to solve problems correctly, because someday we will have to trust it to solve problems we cannot handle.

    There is a mathematical proof verification language, Metamath, whose rigor and/or correctness (meaning freedom from bugs) are probably near the top, if only because (1) the proof language is trivially simple and (2) as a result half a dozen independently written proof verifiers have been coded, in C, Haskell, Python (300 lines of code), Java, Lisp, and Lua, so the likelihood they all have the same bug is pretty small. It stands in contrast to some other proof verifiers or theorem provers that embed complex internal algorithms and tend to be very large programs that would be hard to formally verify for correctness - and in some cases are closed source (like Mizar, which BTW probably has the largest body of mathematical knowledge developed for it).

    A problem with Metamath is that it is very labor-intensive to develop proofs. The proof of 2 + 2 = 4 has 23,000 steps from ZF set theory axioms, and the computation of cosine of 2 to one decimal place has some 75,000 steps that take several seconds for the verifier to verify. All of these steps were entered by hand (although once a collection of theorems are developed they can be reused, so proofs become easier as a body of knowledge is developed). All of these steps are absolutely, rigorously correct - assuming that at least one of the independent verifiers has no bugs. Unlike a 75,000 line computer program, there is no such thing a a bug in the proof - a proof is either right or wrong (i.e. not a proof).

    A couple of years ago I was beginning to suffer some RSI symptoms. While wearing my fancy wrist brace, I realized a lot of my mouse movement on my MS Windows machine was from the top of the screen (where most app menus reside) to the bottom of the screen (where the standard Windows taskbar lives by default). The simple act of moving the taskbar to the top of the screen decreased my wrists motions enough so that I no longer wear the brace.

    Unfortunately many Windows apps expect the taskbar to be at the bottom and will open (depending on prefs) either under the taskbar so they can't be dragged away or over the taskbar obscuring it. I picked the latter pref and deal with the nuisance of dragging newly opened apps down, but that is a small price to pay for less wrist stress.

    It occurred to me that the classic Mac interface has always put the taskbar at the top of the screen by default, so in a sense I have resolved my RSI problem by making my computer more Mac-like. I wonder why MS put it at the bottom - was it just to be different from the Mac?
