  • I can’t give an authorative answer (not my domain), but I think there are two ways these types of things are done.

    First is just observing the page or service as an external entity; basically requesting a page or hitting an endpoint, and just tracking whether you get a response (if not, it must be down), or for measuring load level in a very naive way, track the response time. This is easy in the sense that you need no special access to the target. But it’s also limited in its accuracy.

    Second way, like what your github example is doing, is having access to special api endpoints for (or direct access to) performance metrics. Since the github status page is literally ran by Github, they obviously have easy access to any metric they could want. They probably (certainly) run services whose entire job is to produce reliable data for their status page.

    The minute details of each of these options is pretty open ended; many ways to do it.

    Just my 5¢ as a non-web developer.


















  • Lived at a farm that got some organic farming approvals; it depends on the country. And perhaps even your region. In my country, you can get certain approvals/certifications for organic farming, and the regulations for that is very strict. Things like “chemical” (synthetic) pesticides are forbidden outright, so are strong fertilizers etc. This has government oversight, so, there are randomized sampling and testing done on approved entities (farms, companies).

    Sadly this often leads to higher costs and more land use. Like it or not, a lot of the things forbidden do lead to much higher yields etc. The end result is higher prices; organic (certified) products are quite expensive here.



  • Part of the advertised benefit is that it is indeed blocked by walls and such, allowing very fine-grained segmentation of access. The idea is that you’ll just have more “access points” wherever you want coverage, so, every room etc. But within one room, I believe reflections will allow some propagation, so that things like briefly blocking the direct line of sight won’t actually drop the signal. Also it’s all in infrared, so not visible to us at all.

    Now, to be clear, I am sceptical, as an electronics engineer I can see many challenges here. But I can also see that there are solutions to those problems; it will just take time. The advantages, where relevant, are really big.
