I've been out of the Machine Vision space for a while, so my knowledge is somewhat out of date. What research is out there on general Affine invariant vision algorithms and techniques? For context, my practical experience ended in the

Being able to redefine the problem to get at a "quick and dirty" solution is absolutely a useful skill. What I think gets glossed over in the fine article and in some of the other comments, is that this is really only a good ap

I totally get it; I also need a separate space to switch mindsets. Your setup reminds me of an article I read many years ago on these sorts of "tricks" to stay disciplined when working from home. One of the tips an individual use

You are correct re the Powerwall and Powerpack confusion. I had gotten the information off of the Wikipedia article and accidentally combined information from the two tables. That definitely changes the cost/weight/power equations

Well, a class 8 trucks has a gross weight of over 33,000 pounds. Let's pretend that Musk gets that 1MWh by slapping some Powerwall 2 units on a truck frame. The Powerwall 2 has a capacity of 200 kWh, costs $5,500 and weighs ~3,500 poun

The dojo build system (as clunky as it is) has supported dead code elimination at the module level though dependency analysis for a long time.

I share that sentiment. The complete decoupling of UI presentation and logic all the way up to and through asset deployment via Flex Skins was interesting and had a lot of potential.

PaaS is called Investment Banking. I hear Goldman Sachs does pretty well at it.

Central Minnesota -- cheap house rentals (very few apartments at all) and Fiber optic internet in my city. I've got the low speed plan and I get 5ms ping and 20 up/20 down for speeds.

Well, if you skipped the dormers, the Heathwood doesn't seem too terrible.

The core idea is not too strange, actually. A "normal" crystal has a repeating structure in space; a time crystal is a construct with a repeating temporal structure.

Not a "real" problem on a running system, but back in my first year of undergrad I had a computer science assignment that kept faulting with an "Illegal instruction" error on our Solaris systems. I had a C compiler on my

Probably because the batteries are not discharged to zero, so there is a "floor". If the floor is X kWh, then we can solve for X based on these two ranges assuming the kWh / mile consumed is the same ratio, r. r * (90 -

I built a Machine Learning algorithm about a decade ago for doing this kind of feature extraction. It was targeted for finding samples on a tissue microarray, but it's basically the same problem (find approximately circular features o

I am going to echo the sentiment of a lot of other comments here, but, while well-intentioned, trying to interpret errors and present them in a "user friendly" format is extremely situation dependent. As an example, I had delive

That's true for air heat pumps, but many people (myself included) have ground water heat pump systems; either open- or closed-loop. My unit is fairly old (mid 1980 Tetco) and provide all of our heating and cooling. It uses the most ele

Hey, even small, remote Hackensack, MN (pop. 308) has a Thai restaurant. So it's not exactly mission impossible to find (Americanized) ethnic food in the Midwest. https://www.zomato.com/hackensack-mn/udoms-thai-res

Interesting that the article specifically mentions that the solar panels feed and inverter first, and then power the refrigerator. There are refrigerators designed to work directly off of 24V DC, which would seem to be a more logical choic

The fact that we're at a point where millimeter distances from one side of a CPU die to the other is starting to be considered "long distance communication" is bemusing and awesome at the same time.

Exactly! I did extend it to use a full-screen foreground mask that implemented this sort of clipping. I was able to make the mask scrollable which allowed the compiled sprites to appear "behind" fences and other complex shapes wi

In my game engine I wrote for the Apple IIgs a long time ago, I used compiled sprites and maintained a 1-scanline-wide mask that I used to clip the compiled sprite to the screen edge. This only cost one extra AND instruction and allowed the

This just seems to be a very ranty way of saying that identifying the boundary where separation of concerns takes place is difficult. It seems almost a tautology to me that of course you want to put all the data-related functionality in t

Somewhat off-topic, but I've really enjoyed the "Bartender" manga over the years and its historical digressing into various mixed drinks. I can't vouch for accuracy, but it's an entertaining read. http://

The point of drawing comparisons to the human brain is that we know how quickly humans can perform visual recognition tasks and speed of signal propagation between neurons. Combining these two properties implies that the human brain is able

Totally agree on this point. My feeling is that Rule 9 roughly maps to following the Law of Demeter in that you shouldn't chase properties down more than one level, e.g. Good: var something = obj.property; Bad: var somethi
