We've only been doing it for 35 years over he, it wasn't that bad in USA in 1970s either. :)

You forced me to do it! 😆 If you substract Ukraine and Europenan Russia from Europe (that actually have similar population patterns to the US between Appalachia and 100°W!) and rotate the rest 170°, you end up with something remarkably similar to the USA east of 100°W.

Sweden, a country of ~10M ppl vs. USA.

East of 100th meridian, the distances aren't that different from France, Poland or Romania. Conversely, sprawl isn't caused by country size, we're more than capable of replicating it at countries much smaller.

They drive way more each and every day because apart from brief periods, the prices have been so low.

Tak tady jsem si posunul časem mindset do toho, že bych měl být schopen rozpoznat a bezpečně zastavit před chodcem v černým. V autě se to ne vždy povede (už tak jedu v noci při oslnění protijedoucím a do zatáček a přes horizonty znatelně pomaleji než zbytek provozu), na kole víceméně vždy.

Přidávám se k hlasům "řešit u neurologa a klidně přes pohotovost". Jestli je to něco takového, není to prdel a může se to stát i mladým jako ty...

The reason for yellow/green is AFAIK different: there was a mess of colors in Europe and unifying on blue N and yellow-green PE or PEN was the least painful and most backwards-compatible way how to standardize.

When European legislation for public transport schedule data ?!?!?

It can't be state of 2026 that I need to check schedules of 5 different companies because they refuse to share the public information of their timetables in a machine-readible format […]

maybe a sum of it is that you take an advantage of the technology (ability to have high C-rates) and paint it as a disadvantage.

06.03.2026 13:32 — 👍 1    🔁 0    💬 0    📌 0

Also a large battery makes costs for advanced BMS or for thermal management of outdoor batteries relatively small and the low C-rate turns stuff that wears batteries or makes them unusable into non-issues (differing and increasing internal resistance, time spent close to cell voltage limits).

BTW far greater li-ion risk already in homes are improperly handled tools' batteries, they are:
- of high C-rate
- operated at full voltage range
- stored often at unsustainable conditions and outside of good temperature ranges
- without monitoring that would report faulty cells and warn in advance

I haven't meant to sound like that, sorry if it sounded so. I was just thinking why it's not common to go to a therapist here.

Also, the people with highest need of therapy are the ones most likely to deny it.

How much is therapy as compared to wages in Canada? I've only been a couple of times in my life because it's so expensive (and I can't imagine it being any better if insurers don't help and the psychologists themselves are to have meaningful income, too).

Going back to her husband aftewards seem to me like her proving herself her worth by being able to seduce someone and gain some ground in her own relationship that way?

Once again we talk about how crucially important Ramstein airbase - a huge US military installation in Germany - is for US operations in the middle east and beyond.

As someone who has been working on US drone ops for ages, I have posted quite a bit about Ramstein. Like this thread 👇

So at 15 % utilization rate for ☀️ and →100% for supernova-remnant-heated-thermal-plants, we're at the roughly the same numbers of TWh to be produced?
