One thing opposition to any chemical electricity storage (hydrogen and other fuels) doesn't answer is: _how to transfer electricity across distances?_ HVDC are typically presented as the solution, but even if technically possible, they

Python sometimes feel like being stuck in a local-maximum: the network effect is real, but there are so many downsides to the platform itself, and the "two-languages" paradigm renders the computational code obscure and undebuggabl

But gas is used also in the summer. And energy is not only electricity - heating is currently done mostly by natural gas, and is often absent from those calculations. Efficiency is irrelevant. The only thing that matter is cost and feasibil

This will last less than a day. What to do in the winter? If the answer is "use the grid", then we just kick the can to someone else, who will probably use fossil fuels to provide the energy. The basic problem remains - solar&#x2F

That makes sense. I am still trying to understand why does it differ between a monolith and microservices. The app in the monolith can make the call to non-critical functionalities time-limited and fault-tolerant, just like a network call h

How so? If functionality A is critical to functionality B, how will wrapping it in an HTTP call (microservices) reduce the damage from breaking functionality A? I can see an advantage regarding resource hogging, but the flip side is the ext

False dichotomy. The alternative to AWS is not building your own data center. It's renting bare-metal servers from Hetzner/DigitalOcean. Zero hardware headaches with x5-10 lower cost.

AFAIK the Chevy Bolt does not support fast charging (like Tesla or Hyundai Ioniq). This makes it a different product to an ICE with respect to mobility.

My ICE vehicle averages 30 mpg. We drive ~12K miles/year. At $3.5/gallon, fuel will cost 12000/30 3.5 = $1,400/year. An EV can average 4 miles/kwh. Let's say I go on 4 road trips each 500 miles (charging at $0.

One problem emerging with EV, at least in the US, is that they don't seem to be economically sustainable at a price affordable by the middle-class. Useful vehicles cost >$50K, and a reliable fast-charging network seems to be feasibl

But Google search results ARE not satisfactory. The existence of Q&A forums in the age when information is broadly online (and thus is accessible to Google) indicates a need that is not answered by Google. Google's algorithm may be

Broadly (and of course there are a lot of nuances), studies do not show substantial effect[0], which is a failure of the software considering the promise and the resources invested in this transition. Tens of billions of dollars invested in

So it's all about actual numbers (supply and demand curve). The case of energy (and other industries like transportation and construction) shows that this supply-demand curve be weak enough to lower employee salary. Is there any argume

Are all companies energy companies? While that statement broadly applies to white-collar and services, what percentage of COGS is software in manufacturing? Is it 90%? 50%? or maybe only 5%? Software is useful. That doesn't make it imp

Yet those measures are being circumvented, because physically you can fill the cartridge, and legally, because this physical ability requires the manufacturer to take intrusive measures which are blocked by courts/legislators. It'

This has been debated at length at the past, so I'll pass on that discussion.

What about maintenance of the physical structure? PV panels have no moving parts but: 1. The inverter and other electrical systems do fail (surprisingly frequently). 2. Solar is very spread-out: maintaining a geographically large facility i

Then the GP suggestion seems to have a role again - if net zero emissions is not enough, carbon capturing is needed to mitigate previous emissions. The two are not mutually exclusive.

And the biggest push to invest in re-inventing a software stack is a legal ban on access to the existing software. If previously building a separate CUDA-like framework competed against paying a bit more to Nvidia, now this decision is infi

You can already do that by using the pl/python or pl/java extensions with the right environment. However, the interface between SQL and model inference is typically narrow enough that IMO it's better to: read from Postgres --
