I wrote a super basic 2 axis "autopilot" with Python for X-Plane. The concepts are super simple. Getting the controller tuned properly is not. For a surprisingly large number cases, setting a P value in the 1-3 range and a I value

Vast majority of large, publicly traded companies (at least in the US) only do pay determination (and associated raises) once per year. Promotions can definitely happen whenever but there may be a cycle associated with that as well.

My company does week in-office, then week remote. Quite a bit of flexibility during the in-office weeks too if you have a doctor appt or whatever. I personally really like it. People get stuff done in-office, and then during the remote week

As far as I can tell, the Vulcan (rocket), and the engines, all performed flawlessly. The Astrobotic Peregrine has a uncontrollable propellant leak (not sure if it's best characterized as a leak or something else but the net result is

SCADA networks historically have very low available bandwidth (often due to being on the other end of a 10 mile radio link over 915 MHz with the radio & RTU powered by solar panels) and rely on a poll/response methodology. Even if

Sure showing time and N works. But it'd be a lot easier to interpret the data quickly if it was shown in terms of operations per second. Smaller bars do not usually mean improved performance.

But also experiment with recordsizes of 8k and 16k. The larger the recordsize, the more potential compression you get, which may be offset by additional delay caused by read/modify/write of the larger record (i.e. reading/wri

I believe wind/solar are still cheaper than geothermal. They'll be priorities #1 and #2, with geothermal to make up any difference. edit: and when the sun isn't shining and wind isn't blowing

Edit: Fervo energy is using the same exact techniques used by oil/gas for the hydraulic fracturing so yes the risk exists, but they didn't run into any issues. Seismic risk is typically highest near water disposal wells, which con

The military planes are hit or miss for what they put out in terms of position. Most will do Mode S transponder, which does not, by itself, include position. But if you get enough of these ADS-B receivers in an area, they can triangulate th

yep and you also can get multiple updates per second per plane. I think it tops out at 8 or so which is entirely unnecessary for the radar-style app but you can count on an update between each "scan". https://austinsner

What I've seen is they require fancy materials (carbon fiber, etc) due to the extremely high rotation rates (>100k rpm). For maximum efficiency, the flywheel needs to be in a vacuum to eliminate frictional air resistance losses. The

You have listed the advantages directly from a company that sells flywheel devices. Surely there are no biases here.

You say that but helium is essentially not renewable and is not produced naturally at rates anywhere near human consumption. Not sure if you're aware but helium currently only sourced as a byproduct of natural gas production. https:&#

It's not easy to in general. Gas plants typically operate via cryogenic processes. The boiling point of ethane at standard pressure is -128.2F, so you need to get below that to get everything but the methane to liquefy. -128.2F by itse

Properly "fixing" leaking wells involves getting a workover rig on site and pumping 10-1000 barrels of cement. Not to mention developing a plan and submitting it to the state for the well work permit, which hopefully comes before

There are a lot of nuances to assign the gas a value. Our electricity is apparently in the 5-6 cents per kWh range. I did the math recently and running a generator on site can cut that in half. But then you're in the business of runnin
