There’s no way this will happen any time soon.

I work at a billion-dollar EU company that’s balls deep in Azure after a very, very long migration away from on-prem datacenters.

Cutting off US-based cloud providers would be chaos of biblical proportions.

Does this use case involve US data transfer? Azure seems to have invested quite a lot into implementing EU data residency.

> Machine -> Asm -> C -> Python -> LLM (Human language)

Something that you neglected to mention is, with every abstraction layer up to Python, everything is predictable and repeatable. With LLMs, we can give the exact same instructions, and not be guaranteed the same code.

As long as you consider C and dragons flying out of your nose predictable.

(Insert similar quip about hardware)

It's not about software, it's the underlying technology.

For example, LoRa uses spread spectrum and there are many patents on spread sprectrum in general (don't know about LoRa in particular).

But in SDR, the "underlying technology" of radio modulation, spread spectrum, etc is your software, no?

zurn commented on Data centres account for between 1.5% and 2% of global electricity consumption economist.com/science-and... · Posted by u/jdkee

I won't repeat fact that this number is low.

But the bigger problem with the article IMO is the fact that this is degrowth. Why is the electricity consumption important? Carbon is the real metric. Big server operators (meta, aws, azure, gcp) already either are 100% zero-carbon powered or on track to be.

Regardless, if grid needs to add capacity for EVs, heat pumps, other electrification goals, why are servers (probably low impact) important?

zurn · 2 years ago

Electricity is fungible, so when big operators buy wind-only power from the market, the rest of the demand uses the non-green power left in the pool.

(It still potentially increases wind buildout so it can have indirect positive impact especially if wind is not competitive at the same prices with fossils)

Also the accounting is "we bought as many MWh of wind power as we used" over some time window, so in reality they are using fossil power in peaks, competing with everyone else and placing pressure to expand fossil based capacity.

These are also the reasons it's probably better to talk about the electricity used instead of trying to translate it to emissions by proxy, which is prone to being gamed due to abovementioned reasons.

(Also the number is high rather than low if you consider that all the individual slices of the emisison pie at this subdivision granularity are pretty small)

There are some YAML based schemas there too. How does this work, is there a canonical YAML->JSON transformation, or does JSON schema spec have explicit YAML support?

edit: skipping the theoretical foundations, there seems to be at least this tool that claims to validate yaml against json schema: https://github.com/json-schema-everywhere/pajv

Are there legal and plug and play LoRaWAN devices to setup a shell connection? I'm looking for simple alternatives to internet as a last resort server remote access within 10km urban area, eg between offices, to avoid physically moving to an appliance in case something breaks internet connectivity.

zurn · 2 years ago

You're allowed only very fractional duty cycle access. So depends on what you mean by "alternative to internet", but generally no.

Well that’s cool! In practice, I believe there are portions of the protocol that are patented, so do some research before using this commercially.

That being said, LoRa is a really interesting protocol. Very adjustable to tune for a use case, somewhat novel modulation scheme. LoRaWAN on top of it is well designed. I implemented it from scratch once and was generally impressed with the design. Easy enough to implement and does a very good job and minimizing how long the radio (both Tx and Rx) need to be on.

zurn · 2 years ago

Software patentability is limited in a lot of places, can this actually be an argument in favour of doing things using SDR?

> A good example is housing.

I think housing is a bad example to use wrt Japan.

Japan is one of the few markets in the world where, for the most part, only land has value. Buildings LOSE value over time. This is for multiple reasons but mostly due to ever-changing earthquake-related construction regulations such that it's almost always cheaper to rebuild from scratch than keep an edifice and retrofit to regulations.

This is also why Japan has more architects than any other country- if buildings are not kept and are almost always destroyed after a 30 year mortgage, the owner can build whatever they want and not have to be concerned about resale value- so lots of unique residential architecture.

Alastair Townsend first covered this in ArchDaily years ago and it went on to be covered extensively by NPR and other outlets.

Buildings lose value over time in most places. And in many places where they don't, including renovation investments in the picture results shows declining value.

It's AGPL so might be bit hard to adapt outside of homelab (unless that's the intention for the free version).

zurn · 3 years ago

How does the AGPL apply in this case, does it apply to the apps you build?
