Windows 14 rumored to have a free trial with no limit on playtime all the way up to level 70, including the award winning expansions "Heavensward" and "Stormblood," sources say.

Here's a tiny bit of hopium:

In 2024 we were planning on adding 160 GW of renewable energy to the grid by 2030.

As of the start of this year, we had added 100 GW and are planning on adding 220 GW more by 2030.

(In 2022 we planned for 60 GW in 2030. We hit that by the end of 2023)

i have a habit that when something quippy comes into my head, i search for it to see if anybody has said it already. and if they have, then i don't post it. it's good. lets me get things out of my head and just *drop* them without being attached. recommend this if you're at all plagued by thoughts

Helsinki just went a full year without a single traffic death The capital city is Finnish’ed with car-related fatalities.

β€œHelsinki hasn’t registered a single traffic-related fatality in the past year…Citing data that shows the risk of pedestrian fatality is cut in half by reducing a car’s speed from 40 to 30km/hr, city officials imposed the lower limit in most of Helsinki’s residential areas and city center in 2021.”

I...might've gotten a wee bit sidetracked into modelling uniform polyhedra for a random idea πŸ˜…

At least now I know what a rhombicuboctahedron is (the chonky fella on the right)

How far back in time can you understand English? An experiment in language change

If you liked this experiment, I published a full piece today in the same vein: a text that gets 100 years older with every section, from a modern blog post to a medieval chronicle.

It's a single story spanning 1000 years of English. See how far you get.

Outer Wilds, if you haven't played it yet, is one of the best games of all time. It's a fun space exploration game with a timeloop twist, and 90% of all game progress happens in your head, as you learn things about the universe and your situation.

Absolutely play it if you haven't yet.

i kinda see code bloat the same way i see entropy. it's an inevitable losing battle, but that doesn't mean it's not worth fighting to slow it down as much as possible.

just because you can't build a bridge to last a billion years doesn't mean you shouldn't build it to last a century.

c projects have just as many, often more, dependencies than projects in other languages do. the difference is that c projects don’t tell you about them

I got a great question on my Ramadan thread: do Muslims also need to avoid consumption by proxy in videogames? Does consuming in-game food or drink break the fast? Basically: does your character have to go fast?

The answer is no, unless you happen to be playing Sonic the Hedgehog.

four stick figures on sleds, one is sliding face first, face down, marked "skeleton", diagonally opposite to it is one sliding feet first, face up, marked "luge". The other two combinations are drawn and labeled with question marks

given the existence of skeleton and luge, i postulate the existence of two other, yet to be discovered, winter olympic sports
