I'm cracking 50, and I can't even imagine "retiring". In addition to my dayjob (which is plenty rewarding) I also volunteer for FEMA, Skywarn, ARES, and ARRL. Also looking to get m…

I hate the term "AI" (even though I am CTO of a company with "AI" in its name, but since we use machine learning/DCNNs in our systems, it’s very trendy). The problem with "AI" is t…

I took five years of Spanish -- high school and university (I thought I'd since forgotten it, this was 30 years ago). A few years ago I found myself in Barcelona for a week. First …

This is not a lenticular display. It's a stack of 45 independent transparent TFTs.

I'm CTO of a machine learning/computer vision company, and quite a bit of the team's work is "gluing libraries together" -- but even so, it's an intensely interesting, rapidly evol…

I'd say there's a competition problem in that there are too many very poorly made "me-too's" that aren't even worth the 30 bucks. The Yi's come pretty close quality-wise to GoPro, …

All and all a good intro tutorial that gets into some of the common professional use cases. On "constant bitrate" assumptions and some of the subsequent discussion here, ANY transf…

They have a Yi 4k+ kit with a waterproof action case, much like the GoPro Hero line does.

So, I wonder how many ad placements were made by these companies that specifically targeted experienced talent OVER 40 years of age? I'm going to guess a big, fat, zero.

I used to work for a smallish ( -Off Clause).

It's an interesting conundrum (for my family at least). My father was very highly educated (Professor Emeritus of semiconductor physics/EE at a major University, you've likely hear…

Well, articles like this don't "Upset Me", but I appreciate them nonetheless. In the end, it starts with awareness, but ends in full action. In the meantime, I find myself making c…

Here, I fixed it for you: if (globalservices) { yourescrewed=0; upgradeprobability=0.25f; bumpprobability=0.0f; } else if (united1k) { yourescrewed=1; upgradeprobability=0.10f; bum…

Well, all I can say as a former Continental Platinum (and later United 1K) is that the combination has resulted in the uttermost cesspool of service, fees, annoyances, and outright…

I fly a lot. The only time that has happened to me was when I was on a flight out of Atlanta after taking my crew to a gun range to shoot some auto's. I'm gonna guess the cordite b…

I didn't mean to imply that there were cases where it would Never converge, just that the number of iterations is not a-priori fixed or predictable.

We were doing GPU-based 2D-3D conversion for HD and 4K and one of the intermediate steps required that we compute a DT (distance transform), and JFA was perfect for this. The DT wa…

I was running this on (high end) GPUs back in 2011, in real-time (30fps), on 1920x1080 video textures. I can confirm that the clever recursion and performance of this is mind-boggl…

Yep, it's all fun and games until your ASI goes haywire because of ice or a bug in your pitot tube, see https://en.wikipedia.org/wiki/Air_France_Flight_447#Final_re... However one …

While their approach is clever, it is not guaranteed to converge in a fixed number of iterations. Author states that constrained Delaunay Triangulation is "slow and error-prone". I…

Well, I for one find this pretty cool, especially the part where you can select the altitude. As a licensed remote pilot, this gives me a good idea of winds aloft at-a-glance witho…

For my job(s) the last 8 years or so, I've had a mix of on-site (10%), travel (40%) and work-from-home (the remainder). There have been very long stretches when I'm neither in the …
