This is a great blog post. It was interesting to see how they approached moving from a linear data model to a tree structured data model. Is anyone aware of similar work with graph structured data, as you find in electronic design automatio

No, we should tax consumption. A consumption tax encourages savings, which lowers cost of capital, which is overall an economic stimulant. Most people say: "But wait! A consumption tax is regressive!". No, you are thinking of s

So I grew up in fly-over land. That part of the USA where in Daniel Boone's time "A squirrel could go from the Atlantic Ocean to the Mississippi River without ever touching the ground.", but today is horizon-to-horizon corn

It is my understanding that a dark yellow yolk is from the hen grazing on insects and thus getting insect protein instead of pure grain. But I am not a poultry expert. I know a lot more about cattle and hogs. Some of their numbers seemed od

For a couple of years the ARRL has had some turmoil and toxic politics at the BOD level. BP has a list of candidates he supports in the upcoming BOD elections.

These days 20mA is a "high current" I/O. When you do the math on an 88-pin package, 20mA * N active outputs gets big pretty fast. The max total I/O current can be found somewhere around page 987 of the data sheet... do

It's not like the MISO line is tied to a power rail. You just need to sink more current than the output of the chip you are trying to override. So the driver is likely in the single digit milliamp range, and in any case, you don'

Seems to me that one of the more interesting directions that genetic engineering could take is manufacturing of exotic materials. The safety issues would be much easier to manage as well if the GM organisms are kept in vats in a lab instea

Boston Dynamics mainly did DARPA contracts for a long time. And their stuff had a certain reputation... "If the contract said MTBF > 10 hours, then they pretty much ran for 10.5 hours." They really have little expertise in de

AFAIK it dates back to the 1930’s when spy networks were HF Morse code. Clandestine ops used HF morse well into the 1970’s, perhaps later. Pretending to be a ham was a form of cover. Sadly, being a cracker-jack Morse code operstor doesn’t g

Yes, you can update the device. My comment was more about how Numworks can practically integrate Micropython updates. It seems like maybe it could be a Git submodule so that changes were easier to merge. Tracking Micropython bug fixes and e

It should be pointed out that this is Micropython, not the Python that you are probably used to. Micropython is great stuff, I’m a huge fan, but it is different from CPython in noticeable ways. They seem to have simply copied a source snaps

I don’t think they are qualitatively “better drivers”. But they are more experienced at certain things. When I lived in Minnesota, I got lots of practice driving in snow and ice and rain. Now in NorCal, not so much :) Its a skill. You get b

Farm land borrowing is through completely different organizations from home loans. Farm Credit Association, for instance. And the backer is FmHA, the farmer lending equivalent of FNMA. Farm lending is not nearly so highly leveraged as hom

Yes and no. Some some farming is naturally profitable. But much is subsidized.

I assume what you are saying is to assume a 1 in the MSB of the mantissa. That has been done. HP minicomputers, I believe, and maybe some orhers of that era. Unfortunately, that means that you have no way to represent numbers in the denorma

The "deal breakers" checklist skirts the true issue. I have been married longer than most HN members have been alive, which is no accident. So I'll temporarily be arrogant enough say my peace on the theory that someone might

It's not. The shock wave is present as long as the plane is in super-sonic flight. I grew up in fly-over land, and military training flights based out of the Dakotas used to go overhead; we would get the occasional boom. (Also, once i

Well, that isn't a straight-forward problem. Take Atlanta to Zurich, for example (a Delta flight I have been on). Conventionally, the plane flies up the East coast until it clears Nova Scotia, in part because that is approximately the

I have not studied Go. I am learning Rust. I am not current with C++, but once was fluent. My take on Rust (as a Pythonista) is that while C++ is tedious and error-prone, Rust is merely tedious. Which IS progress. But... if you want to up-l

Interestingly, “Amazon Basics” has no counterfeitting problem. It is not that Amazon can’t fix counterfeiting, they just don’t care unless it is their own brand. At some point this crosses the line into anti-trust territory.

At my time at Intel, the company was fab-constrained. Intel ran some parts on outside fabs. The decision as to which ones was easily made by sorting projects in order of gross margin per wafer. Highest margin parts ran on Intel fab, when

Absolutely. Birds lighten the load for takeoff. As a kid I remember many small songbirds nesting in the (large, country) back yard, and a pre-launch ejection was almost guaranteed. Avian digestive tracts are simple and not particularly effi

I’ve had that. But not from anyone I cared about after going through the interview. Unsurprisingly.
