It's certainly a possible solution to the last mile problem, and one I've considered using myself, but the issue is what do you do with your transport once you arrive at your destination?

If your destination is a home or office, you can just take it inside, but what about a bar or restaurant? Leaving a bicycle outside is an invitation for theft and it's certainly too large to bring inside. Even a longboard isn't exactly simple to tuck under the bar or lean on your table.

This is exactly what several electric "bicycles" do now. They have a road mode which conforms to the federal 750W/20MPH limit, and an offroad mode that allows something like several kilowatts and perhaps 40MPH.

I doubt they're taking a loss, and I'd be surprised if they're not making a decent profit. What are the components? A 1080p cell phone screen, some cabling, custom plastic enclosure and straps, an IR webcam, and the PCB+components. That's not much, cost wise.

Duopoly? A large number of major cities and their suburbs only have 1 true highspeed option (cable) and slow wireless or DSL. FIOS deployment is sadly limited.

Aside from cost, what do you think makes a Tesla impractical for the "vast majority of drivers"?

I also backed the Hexbright. You're remembering that you'd have it by last Christmas because that was the original shipping date. I think the FAQ was changed once the delays were announced. I agree, it looks like we'll be getting a great light, but it took entirely too long, imo. The creator had a video with a functional light during the backing phase, so I assumed it was nearly complete, but sadly it wasn't the actual light we were backing in the video and development took a year longer than expected. The creator has been perfectly upstanding and handled things quite reasonably, it just took far longer than expected to design and manufacture the thing, sadly.

This, a million times this. My understanding also is that the ODB port on many/most vehicles goes straight into the CAN bus controlling everything in the car. It's entirely possible you could gain control over any microcontroller in the car, send false messages, drown the bus, etc. through a device like this. It's a TERRIBLE idea from a security perspective.

I'm not sure what you're seeing, but Linode is right under Heroku on the right side "your web server" list.

My thoughts exactly. This is just complexity for complexity's sake. Useful as an exercise, but the -h flag already does this is an even more readable manner.

First of all, this is something that's always bugged me when using twitter, and I like seeing someone address it, but I have a comment. I agree with the 13" laptop screen examples, but how many people browse the web full screen on monitors over, say, 21"? On my 24" monitors (1920x1200) I usually have browser windows dragged to 2/3rds of the screen at most. Most websites look patently ridiculous at full 1920 width, let alone 27" or 30" monitor resolutions like 2560x1600.

Ah, thanks for the information. I'm familiar with signal processing, so the only way I'm used to seeing convolutions is through the multiplication of FFTs. I wasn't even considering the "regular" way.

As far as I'm aware OpenCL performance, while portable, is still somewhat inferior to that of straight CUDA on NVIDIA GPUs, hence my CUDA suggestion. I didn't actually look at the algorithms used in either so I can't comment, perhaps I'll do that tomorrow. What do you mean by using an FFT "for" a convolution? The algorithm is convolving the (presumably 2D) FFT of the game board with a disk filter?

But you missed the most important part of that quote. >"(in Ready, Stephan's software at the sourceforge link above runs much faster)" So using Ready it took a long time, but the actual code is much faster. I'd imagine you could write something in CUDA that would run this (and only this, not something generalized like Ready) plenty fast to do real time rendering on a new system, especially considering a GTX 680 has almost 5x the horsepower of a GTX 460.

Admittedly not in a web browser though.

Two thoughts here. 1) You're working from an awfully small sample, especially for a component that is supposed to be of such a high reliability. Then again, look at the probabilistic assessment of Shuttle success vs. actual. 2) The Merlin 1C engine is only going to make a few more flights afaik. Starting some time in 2013 they'll be switching to Merlin 1D.
