With more outages of our amazing, but overly centralized development ecosystem, the popularity of this approach will likely surge. It helps that Go supports the vendoring workflow as it makes the choice practical. As for building with a fla

In Go, it's customary to use 'go mod vendor' to put your dependencies into the main repository. While it's not universally recognized as a good technique, it saves the adopters of this approach from the downtime today.

Thank you for these insights. I just want to add that mesh wifi is not necessary here. Given the amount of bandwidth needed (very little), LoRaWAN (1) with its ~3-10km range will be quite practical. 1. https://en.wikipedia.org&#x

Specifically Hetzner required me to put a deposit, when I rented a server a few months ago. It was a reasonable amount, and you're right about the reasons. Edit. Found their message: "At the following link you can upload the copy

That's a fair point. Let's compare: GM sold 7.72 million vehicles in 2019 ([1]), which was before shortages. Tesla will likely ship around 0.9 million of vehicles in 2021. So, yes, the point is correct. There's still an order

Before shortages, GM revenue in Q3 2019 was $35.5 billion. A bit more than $34.2 billion in Q2 2021, but very close. Edit. You're right. By the number of cars, there's still an order of magnitude gap (see my other comment). Thank

GM revenue in Q2 2021 was $34.2 billion ([1]). Tesla Q3 2021 revenue is $13.7 billion ([2]). Tesla is still smaller, but it's in the same order of magnitude with GM. 1. https://media.gm.com/media/us/en/gm

I am personally rather a pessimist about the whole thing (despite being a fascinating economical quirk), but yeah: people repeatedly demonstrated that they will do anything for profit. That said, direct coal pit to furnace to mining rig pip

I predict that in 10 years, a secret nuclear power plant will be uncovered that was built specifically to mine cryptocurrencies. And the construction costs would be 10x lower per Watt of output than what we see in the conventional nuclear (

I mostly agree with the comment above, but I want to note that China does not need the US to build the reactors: they are already doing it themselves. "As of June 2021, China has a total nuclear power generation capacity of 49.6 GW fro

Yes, me too. But Iridium recently (2017-2018) launched the new constellation that they call Iridium NEXT which supports L-Band and offers significantly more bandwidth. So, it's now possible to get a 1GB plan for ~$1300/month ([2])

Saildrone is a startup; its primary customer is NOAA, the US Federal agency in the question. From my impressions, NOAA is a very useful agency that delivers on its mission pretty well. But I never interacted with them directly.

Based on the photo from the NASA website ([1]), they use a Thales Satellite modem ([2]). My best guess it's VesseLINK 700 ([3]) that uses Iridium Certus constellation ([4]) and costs around $8K ([5]). Key Features: * Robust, Light-Weig

The cruel part here is retroactiveness of the change. Pioneered by California's Proposition 30 in 2012 ([1]). Retroactive changes of the (tax) law reduce the planning horizon and ultimately the efficiency of the economy. 1. https:&#x2

RealSense cameras are/were pretty good. Lower latency than Microsoft Kinect Azure (~70ms vs 300ms), decent depth quality and a well-maintained open source SDK.

ML training is a latency sensitive problem that benefits from locality: most of the learning algorithms wait for all parallel workers to send gradients back before updating weights. While workarounds exist, life is easier without them.

This sounds very doable, given how many made-to-internet-order manufacturing options are out there. And I agree: it would quite useful to many.

One counter example: the Go team, when it started (Rob Pike, Ken Thompson, Robert Griesemer, Russ Cox, Ian Lance Taylor), was quite senior. But they did deliver.
