It's been a struggle to allocate cost-optimized VPS at them for months now (in some regions), they were very often out-of-stock.

Btw. the western list price is just an indicative at-most number anyway. Even a small-sized project gets discounted prices when you start talking to a sales rep.
In case of gaussian noise, double the bandwidth means 1.41x more noise. For signal, double the bandwidth double the signal.
When successful POs write a book or something, they present the best-practices. They don't share the most important wisdom though: there are pretty smart to start with... Applying their practices without the ability to think does not work, and it's not something one can pick up on the go.
Nothing comes from nothing.
- $104k at ($55 / 100 GB) = 189 TB of traffic
- It means the popular ~3.5 MB media file was downloaded ~54M times
- Which sound like a lot, but if you get popular in a country with 1.4B people, it's not (~3% accessed).
What if it happens at AWS Cloudfront? At $.1/GB it sums up to ~$18k. In the light of these, Netlify's offer of ~$5k seems generous.
You'll see great LED installations at:
- offices & commercial buildings, where it was designed by an engineer
- medical, where identifying things like skin-tone is critical
- transportation (often street lights), where it's optimised for night-time contrast
Here's a free tool that helps designing such fixtures: https://www.meerkatblog.com/ledmixing
There is no need of official government approval to conduct such surveillance. It's enough to have weak access contol to such technologies, political roles within the agencies, and poor work ethics in civil servants: there alway will be someone with will and motive to act in favor of the system, off the record. Orban deliberately shaped the government this way.
Btw if your plants look healthy, no action is required.
I think most assembly-houses self-source some parts, and they do it in large quantities (like 1M+ parts/year). As such, they buy at extremely good prices. They overbuy themselves, and in order to get the same good pricing next year, they keep overbuying. Some of their inventory is then sold locally, and ends up in the Shenzhen market or at unauthorized resellers.
For the quantities I buy (sub-1000 pcs typ.) the pricing is usually 0.2-2.0 times the known good parts from known (authorized) sellers.
The problem is that I can not be sure what I get, and I have to implement really extensive testing for each batch.
What's really happening is that I (and likely many others) realised that Chinese-brand chips (which are not affected by the shortage) works just as fine as the western ones.
The other thing I realised was that non-authorized sellers works just as fine as well. Yep, I had to implement more thorough testing/QC, but I would not call that extra work innovation.
I think the source is rather an unintentional radiator in this case.

Far field emissions rarely comes from pcb traces though. Memory (high speed) buses use amps of current on each transitions, and the return current create a significant (few mV) voltage drop on the internal ground and power planes. This results an AC voltage difference at the opposite ends of the bus on the same plane.
Take a look at the Raspberry Pi 3: it has a power usb connector at one corner, and the USB A connectors at the opposite corner. The memory/cpu are inbetween. The shields of these connectors are connected, and are connected to the internal ground. When the device is operating, there is likely some switching noise between them. When you connect a USB cable, the shielding on that cable and the shielding in the power cable may act as a dipole antenna. This is the most likely source of emissions, and the metal casing does little to nothing to prevent it.
I know two greenhouse growers, growing the same variety of tomato on the same rootstock in the same medium. One of them has ~5-5.5% DMC while the other has close to 8% in the mid-spring season.
They taste different, but they yield different as well (higher quality means lower yields).
(CubicSDR ran on the same DELL machine, however both tones disappeared after disconnecting the antenna from the SDR)

water use is necessary to manage internal climate. the greenhouse was designed to keep heat inside. the plants have to cool themselves (hence the environment) by evaporation. the farmer manages evaporation rate by watering, temperature and humidity. there are many feedback loops, both negative and positive, balancing it is a non-trivial task.
btw. there's an average of 1.2-1.3 plant/m2 in most tomato greenhouses I've seen.
1. there is an existing technology called energy screen/curtain, with the primary function of retaining heat, but can also reduce light pollution by an order of magnitude.
2. light that escapes is essentially money lost, however it alone does not justify the use of energy screens.
3. as long as farmers have access to (relatively) cheap heat and electricity, they won't invest into this technology.
4. for the time being, it's a regulatory issue, just like water use (a single plant use 2-2.5 l/day), supplemental co2 use and nitrate recirculation from runoff water.
As the heater block is integrated to the tip itself, you get better thermal characteristics (quicker heatup / less thermal runaway). Search youtube for comparisons to Weller/Hakko irons, there are a few.
