Shazam for fonts. Point your phone camera at some text and it tells you the top N fonts it thinks it is with C% confidence. Niche market for graphic designers. There's the website What The Font [1], but it's not a super user friendly app like Shazam. I think the hardest part of this would be the huge amount of time it'd take to get a good dataset and train whatever machine learning model you'd probably wind up using.…

dataset could be provided through google fonts maybe. you'd need to replicate a few iphone camera quality versions for each font though.

any links for machine learning images? I could give this a go.

I sometimes even registered the domains, e.g. toothing.org The name offers various cell phone games, even the toothing hoax itself.

The next odd idea requires expert knowledge in Babylonian contracts. Every change of ownership without a contract was theft. Contracts involving people required a cancel clause for each side. And ownership on people without contract was punished by death, as illegal slavery. So most contracts are marriages. The contracts are highly formalized, so one can use them as templates and exchange the names. Print them on a clay tablet, burn them, and send them by mail. I'm sure marriage contracts would sell, especially those with the cancel clause: "and when she says you are no longer my man, he can throw her into the river".

The 3rd and most challenging idea would be a project and freelancer site that does not suck. Where projects, prices and skills do not race to the bottom.

And last shameless plug about something real You can contact me on #o3db @ irc.freenode.net - currently developing a Browser-4GL in Scheme.

Nice idea. I think you will find the hardest thing will be that so many typefaces are near clones of each other. It might be easier to just match to the closest open source typeface.

Indoor almond farms I don't mean as a hobby. Industrial scale, genetically modifying the almond trees for better indoor results. Global demand for almonds will continue to vastly outstrip what California can handle via traditional outdoor growing. That would have likely happened even without the drought. The water requirements will place a cap on the almond industry's growth. The solution is drastically more efficien…

Wouldn't the simpler solution be just move the Almond industry out of California to somewhere with better water?

My understanding is there are only a few areas in the world climate suitable for commercial almond farming. Among them Spain, areas of Australia and California (which produces most of the worlds almonds). Move the Alfalfa first. It uses in sum more California water than almonds and you can grow it in many locations.

Incidentally, the idea of growing almonds indoors is just plain nuts:)

You would have to have a lot of indoor space and the return would likely not even close to cover the cost. Ever. Even if almonds cost 5 times as much. Even if you bred little tiny almond trees (which could probably be done as they have miniature peach trees and vertical espelied peach trees and almonds are essentially a type of peach pit)

For the love of God, someone create a World of Warcraft where the quests are educational. Instead of "go kill 8 green dragons" the questiver says "Mata a 8 dragones verdes". The immersion and addiction to progression (i.e. unholy motivation) would have us speaking multiple languages in no time.

Please. I'm begging you to take my money.

Rooftop solar has really taken off here in Australia, and around 20-25% of houses have a solar inverter. Is it practical to build a cheap rooftop wind-power harvester that plugs into the inverter?

The killer here is likely to be planning restrictions. The other problem is wind is actually more efficient when centralised. The large turbines that our PM hates so much are much more efficient than small turbines.

Agreed on both points.

With planning restrictions, I hope that something small and noise-free could please the nimbyists. Something(s) the size of a Dyson fan on the roof-line would look cool.

With regards efficiency, I think it's not about replacing the large centralised turbines but augmenting the house's existing solar. A typical single solar panel that generates 200w peak makes about 500Wh/day (on sunny days). If (big if) a turbine can generate 20w average over 24 hours, that's 480Wh extra.

But as @desdiv correctly points out - the idea is nothing new. Here's a good looking 20w turbine that I would be happy to have on my roof:

Earlier quoted context omitted.

Yes, I should have been more specific - I was thinking of something much smaller that could sit along the roof-line of a typical suburban house. The site supplies separate wind inverters too. I guess that means that the turbines supply very different power to solar panels.

The vertical turbines are quite small. Here's one at a house in Brisbane near where I live: https://www.google.com.au/maps/@-27.50561,153.05533,3a,75y,1... I suspect there's issues attaching it to the house itself, but for houses on the top of a hill such a setup can work well. That thing gets spinning really quickly some days.

That's a great example - is it in a particularly windy area? I will look into installing something like that.

Amazing post-game experience for recreational athletes.

I play soccer recreationally. I've easily played more than 1,000 games and all I have post-game are memories ( which are nice ), but I feel we could do much better.

I have a vague idea for a solution - but it would involve drone-filming all my recreational soccer games, and then have the content edited/produced - so I could see al my plays, everyone else's best plays, and so on and so forth.

It would be really interesting because it would also augment the social in-pitch experience with post-game online socialization.

What do you think?

An Amazon for renting things. All the top Google search results looked antiquated.. edit: my search query was just "rent anything"

That sounds like a bad idea from a counter-party risk perspective. But I suppose so did AirBnB.

Everyone says AirBnB was a bad idea, but only the original idea was bad. Once you realise that the business is really about running illegal hotels where the risk is outsourced then it becomes a very good idea.

The areas that are suitable is a function of the price. If the Californian Almond industry runs out of water then other more marginal areas will become viable.
