I am a big fan of SQLAlchemy, though I often use it more as an advanced pythonic query builder than as an ORM It can sometimes be a bit more work to write something in SQLAlchemy than raw SQL, especially when doing complicated queries, but

You are correct, let me rephrase that: I separate plastic so it can be either burnt together with my other trash, or shipped to Turkey where god knows what environmental crime is committed with it. An extremely small percentage might be mel

Though I initially sympathized with the name change from master to main (cause I don't care what it is called), I am now more of the opinion that this kind of window-dressing might actually be harmful as it distracts from addressing th

A strong argument against nuclear is that the costs and benefits are very spread out in time (random numbers follow) say: 10 years of construction, 50-70 years of operation, 10 years of decommissioning. Who is willing to make an investment

Why solar not an option? The Sahara is really big, has plenty of sunshine. And population in a lot of upcoming economies are already used to supply limited energy grids. Maybe they can more easily adapt/grow into a power grid that meet

Though not so nice, there are ways to "stabilize" sovereign foreign countries to ensure energy stability. Just look at US middle eastern politics. Not saying we should, but I'd rather have the effort got to solar power in the

I would like to see the numbers; how much overbuilding would be necessary. Even if you need to install say 50%-100% extra capacity to meet demand in winter, solar power would still be perfectly economically viable. And I'm sure a vali

Some (often desirable) properties of RDP for timeseries is that is preserves details at extreme events and does not shift peaks. Very useful for e.g. seismic data. I have compressed tons of data with 1% subsampling with hardly any informati

Additionally we will need to live with a supply constrained electricity net. Sometimes there just isn't more available and variable pricing will be needed to reduce demand. Of course the Texas power crisis showed that even if prices ri

But not impossible! Just look at the COVID response. Massive and sudden cultural/behavioral change is actually more achievable than I would have thought last year, as long as the sense of urgency is sufficient.

I recall having MSN on a symbian smartphone just before iPhones even existed. Really cool and all, but I could only communicate to a handful of people with it. SMS was the de-facto only way, always 1-1 and charged per message. Internet 2g&#

And because of this ship it is easy to see how expensive topside removal must be. The vessel costed some 2.5B or so. Recovering that in a few dozen decommissionings means a Hugh price. And don't forget the operational cost of a crew o

You could also use the array to store only the order, and regular FK relationships for membership. That way the referential integrity of the items is guaranteed, but the order is more of a "best effort" approach, as in that there
