Computational geometry is a real challenge for python because it requires object oriented design and is speed critical. It is a marvel of technical engineering that this was possible with CGAL, but I don't see this working out unless you have a robust python compiler that is able to remove the various `if` statements that are handled by templates in C++.

If I was to do computational geometry in python, I would wrap CGAL.
How much does competition account for the "impatience" that Uber's seeing? When I launch Uber and see a "long" wait time, my immediate reaction is to launch Lyft to see how long their wait time is. Not that Uber would go sticking info about their competitors in a blog post, but you wonder if there's any connection between the "patient" cities and how much mindshare competitive services have in those cities (i.e., no competitors outside of legacy taxi companies = people willing to wait longer).
Microsoft to invest in Cyanogen, says report
This doesn't always work, the Greater Toronto Area (GTA), even if you take the most narrow interpretation, is made up of a bunch of different transit systems. Walking along on Google Streetview, there is no way you could tell when on Yonge Street you have "left Toronto", and need to pay extra fare on TTC, or take YRT/Viva/Blue etc.

But it's a neat idea to think about transit and accessibility. I'd love to know at which point in the world you can reach the most people within an hour of transit for example, or two hours... This is the advantage in the Pearl River Delta (and probably Tokyo) - there is tons of high-speed rail, subways etc, so you can probably reach about 40 million within 1.5 hr (an hour high speed rail and half an hour on local transit). Whereas it takes me an hour and a half just getting to the airport in Toronto.
A few corrections.

Within the US, little electrical generation comes from oil (about TK%), but outside the US that level's rather higher -- something I only learned recently myself when trying to rebut the statement that oil was significant in electricity generation elsewhere.

Hrm. Still not all that big. 256 Mtoe per the IEA in 2012, of 6,497 MTOE, about 4% - 6% depending on how you read net global imports / exports. (How does the world import/export to itself?)

Though in many parts of the world, electricity comes from gasoline or diesel generators on small scale rather than central generation plants.

There's also the fact that renewable energy can produce liquid or gas fuels via the Sabatier process (resulting in natural gas) or Fischer-Tropsch fuel synthesis (liquids). These aren't used in bulk now, but could be, and represent a possible carbon-neutral gas and liquid hydrocarbon fuel source in future.

1) That's what I suspected.
2) What if I force them to hold my hand so that I can show them to how to properly use it and convince them that it works?

Since first impression is so important, and the product needs hand holding to demonstrate it's value, my free trials would essentially be hurting me.

There are some video files that give a lot of trouble so it's really to support their very custom requirements as the product for the paying users works fine. It's those people that want the custom work done for free which I don't think is a great people to target.

If there are any materials you could choose to use that are vastly more expensive than asphalt, glass and solar panels are right up high on the list. The price of a solar roadway would be staggeringly higher than a regular one. (Currently, most of the cost of roads is labour, earthworks, concrete piling, steel structures, etc.).

But solar roadways are ridiculous for another reason - first, putting a solar panel under a thick layer of glass will lower its efficiency greatly - because the thickness of the glass will reduce light transmissibility through it, making the panel far less efficient than a regular one on a roof etc... Secondly, the glass is really slippery, and the only way to fix that is by texturing it or coating it in something, both which will reduce transmissibility even more. Next, if you've ever dropped an ice-cream on the road and the picked it up again, you'll know that roads are ridiculously dirty. The dirt and grime will build up, just like regular roads, reducing the efficiency even more. Then, the cars driving over it will grind that dust into the glass, and any abarasive material will put tiny scratches in the panel - which over time will build up and again reduce efficiency further.

Dave Jones from the Electronics Engineering Video Blog (EEVBlog) did some calculations in one of his videos - assuming optimal efficiency. Even then, a panel would not make enough electricity to pay itself back (can't remember the time period exactly - over 20 or 30 years? Or perhaps it was the estimated lifetime of a panel).

But with all these extra losses, there is no way it would ever work without huge advances in solar technology and materials science.
Access to 3% of US gas station real time data should be enough to give you an edge in open markets. It might be enough to find mispriced stocks before earnings. Not that I'm suggesting anyone should do such a thing.

> The problem for Microsoft isn't that they didn't see mobile coming and Apple did

They did have a mobile operating system, a mobile .NET framework for application builders, and a bunch of early PDAs shipped with Windows Mobile.

Apple just managed to redefine the mobile market completely, and make Nokia, Sony/Ericsson, Research in Motion, Kyocera and others irrelevant. Those others were supposed to be producing hardware devices that would license Microsoft's mobile products.

So they had a vision, just turned out to be wrong.
A long time ago (though admittedly in this galaxy) I made a computer game with moral choices a key element in the gameplay. I named it Legacy. It was a Java GUI app. Though a small game in terms of feature set and code size I always remember noticing how it was one of the more fun (to me) games I ever made. Had to do with mating, family and inheritances. It ended up influencing my more recent designs as well.

For users that abandon it, you could process the video that they've already uploaded and email the results to them, along with a short screencast/tutorial of how you did it? As long as there aren't legal/ethical issues with doing that.

The original BioShock was better in going meta on the futility of choice in video games as a medium. You're going to end up doing what the game designer wants you to do. This presumes a game designer has a vision of some sort, of course, but games that don't are either bad or seen as tech demos.
Analysis of Apple's marketing psychology on product depiction (German)
One of the reasons I am frustrated about a long waiting time is wrong expectations set by the map. The map in SOMA typically shows that 5+ cars are within 2 minutes. As soon as I request, the closest is 7 minutes away.
In this article Apple's product depictions are analysed for their psychological subtext. The author found indication for 3 different types: evolution, family and winners/winning.
It can be useful to do things manually and hold users' hands at the beginning, so that you get a much higher-bandwidth feedback channel. However, if you want to end up with a viable product, the product will eventually need to be simple enough that someone can use it without you explaining it. Otherwise you have a consulting/systems-integration business, not a product business.
Completely agree. Just compare Athens or Lisbon subway with Berlin subway. It seems that Germany is the most poor of these countries.

It works for majority of cases but still the tail scenarios where it will choke. those edge cases consume majority of my development resources.

Ironically, one of the projects I created with what would seem like the least amount of practical use also got the most positive feedback. Sometimes when you just do what you want for fun and self-edification, it results in a project that shows more passion and finesse than something banged out for more cynical purposes.

It's one of the things I struggle most with, besides the relentless self-consciousness that comes from being a 33-yo trying to retrain in a technical profession, is feeling like all that stuff I love has rather minimal crossover with the stuff that might pay the bills ...
If you voted based on mathematics, you would see that you are mistakenly conflating your individual vote with the behavior of the general populace. For example, with the presidential vote, except in a couple small districts in swing states, your vote is completely irrelevant. Your single vote is both not enough to swing the state you are in, and even if it were, it's within the error margins for that state. If it ever got close enough to where one vote decides it (and it never has), it would be a court deciding the vote anyway.

So since your individual vote doesn't matter, you might as well vote your conscience and not pragmatically.

I can't speak for every school, but I will share my own insight on a big football university

I attended a state school where the "highest paid public employee" was a football coach. I was lucky enough to marry a then student president of the professional students (Med, Vet, Opt, Dentist, Pharmacy, Law) and as part of her duties she sat on the athletic counsel. Our tuition did not go to the coaches at all, the athletic dept was entirely self funded and donated the excess to the school itself. They helped fund a library renovation while we were there, among other student oriented needs.

Also, because of the success of the football team they are able to fund (again without student money) all the other sports "no one cares about" eg men's badminton or women's olympic weight lifting or something... The majority of THOSE student-athletes truly are students then athletes.

Take away the good football and the other things become harder or impossible to achieve. I'm not saying sports should be considered a loss over academics, but some people enjoy both and are not going to the NFL

> with the Japanese system, use the proceeds to help offset the initial costs, just like with a toll highway or bridge.

The U.S. system isn't free. The cost is embedded in the goods/services you buy. The Japanese system just removes the freeloaders, because parking is so abundant in most of the U.S., we don't really have that problem.

Although, I have found myself parking in weird places to avoid the valets. Valets now seem like some requirement everywhere I go, in my city at least. I feel like it's actually a disservice in most instances so I try to revolt when I can.
I think thats a good point. Eventually the product would've have to be a low touch, self service but for the niche I'm dealing with that's unlikely to be achieved with the resources that I have. Even when I do, I think there will still be those that fall through the cracks, I think that there will need to be a dedicated customer success manager or something like that to ensure that they are using it successfully and most of the time it's that they are using the wrong configurations or the source of the video file is extremely bad (choppy audio, weird artifacts etc).

The tail, edge cases make up a lot of the use cases (as I can observe so far), it almost always require additional development effort. However, I don't think I can do those work for free and hope that they will buy when it's ready.

I think I will actually consider removing the pricing pages, demo section and setup a "Call For Demo or Pricing" form that asks for phone number and company size.

I am focused on sales so maybe having a consulting + software type of business might work better.

Pros:

- Portable (as long as you don't need dlopen/dlsym). If you do need to dlopen other libraries, you can run into issues on ARM mobile with mixed soft/hardfp calling conventions. Otherwise you're fine if the ABI is solid.

- No need to atomically update your system, as applications stand alone.

- Slightly faster program startup time.

Cons:

- Slightly larger file size (assuming you linked glibc... doesn't apply so much to things like musl or lib43).

- You can't link in OpenGL client libraries, so games will probably still need the dynamic linker.
That would explain a lot of the hatred on reddit, for instance.

Right, and then they distributed it among the people so they all had enough.

People with property sold it. People without property didn't sell it (because they didn't have any to sell). The apostles took the money and gave it to those in need. It wasn't a black hole of money where the apostles took it and used it to pay rent on a church building that people were encouraged to visit, the distribution was to people to meet their needs.

Without having been there, I imagine that the way this played out was that everyone gave everything they had, then the apostles worked out what the needs of everyone were, and then divided things up so everyone's needs were met. If people tried to hold something back then this just makes the practical matter of dividing things up much harder (instead of being able to say "each family gets N things plus M things per child", they need to take into account whether the family already has stuff and reduce N and M to compensate). Yes, the sin of Ananias and Sapphira was not that they made logistics difficult, but I do believe that what they wanted to be able to do was to just do a simple job of just distributing things fairly and transparently, and people holding things back made that impossible.

Giving money to a church makes a lot of sense, and is clearly biblical. Using that money wisely also makes lots of sense and is biblical. Churches that invest this money in expensive mixing desks or outrageous rent when there are people in their congregation who don't even have a place to sleep are not making good use of the money they are being given.

My opinion is that if a church has a regular person in their congregation who is lacking food and shelter, and the church is collecting money from people to spend on things like sound desks and coffee machines, then that church is stealing. People who give money to a church are giving it with the expectation that it be used in a way which is in line with biblical principles, and to be spending it on luxuries for the affluent when there is such obvious need is unconscionable.

It's definitely a sign of maturity to be able to treat sports and people who are obsessed with sports seriously when you know better. The fact is, the truth is unfortunate. Professional sports are a bunch of grown men playing little kid games who receive an incredibly and disgustingly disproportionate amount of money and adult attention.

I believe that children and adolescents playing sports is fantastic. If people want to continue playing into their adulthood for fun and health, that's great too. Casual interest in sports is fine with me. I prefer to see participation to spectatorship.

What I and many other people have a problem with is sports in schools and professional sports being treated as if it is intensely important, more important than direly serious things that keep people alive, fed, free and healthy.

Top 3 Swift Tutorials in January 2015
Terrible show. I can't speak to episode 3 and beyond because I didn't watch it, 1 and 2 were so bad. I only saw the episodes that were available on Netflix. Episodes 1 and 2 (PM Pigfucker and Reality TV Ad World) were HORRIBLY paced, slower than molasses in January, with so much wasted time that should have been either cut, or filled with more story. Instead, we're given the basis of the episode in the first few minutes, then we get that concept beaten like a dead horse for 30ish more minutes, then a completely unsatisfying ending. There was a minor twist in 1 that could have been more enjoyable were I not so annoyed at how bad the rest of the episode was, and the twist in episode 2 was just obnoxious and completely unoriginal. There were so many moments they could have done interesting things with what happens in the episodes, but instead, they just leave half finished statements all over the place. A complete waste of time, money, and talent.

It reminded me of Blair Witch, which was a fantastic 20 minute short film that for no reason was padded out with an additional hour of footage of snotty college kids crying and yelling "FUCK!" in the woods.
Adding on to the praise, I wanted to also comment -- thanks for doing an analysis of the results. Having implemented it was neat, but the honesty in revealing that what you've built is an interesting experiment, but not necessarily an improvement on the status quo, is commendable.

There is still lots to be learned from the work you did -- both the technical and the analytical. I think this is probably the most striking example I've seen recently of "negative results are results, too".

I suspect that technology can be a great learning tool if:

1) The computing environment encourages kids to practice problem solving, critical thinking, and systematizing.

2) The kids are intrinsically motivated to spend their "screen" time using software that encourages the above, as opposed to any of the myriad distractions on computers.

#1 is a problem of finding and identifying the good software in the haystack of diversions.
This was easier in the pre-internet days because computers simply had far fewer consumer-oriented features.

#2 requires that kids actually be interested in and disciplined about thinking deeply about problems.
It also really helps if kids have a problem that they personally want to solve, which motivates them.
