Trickier than expected! I ran into an issue with Lua patterns, so I had to revert to a more verbose solution, which I then used in Hare as well.

Nach emotionaler Debatte: Grüne stützen verschärfte Asylpolitik (www.tagesschau.de) German

Vor allem junge Delegierte üben in der Debatte scharfe Kritik an der Asylpolitik der Ampelregierung. “Es ist unehrlich über Begrenzung zu reden, während die Welt in Flammen steht”, sagt Vasili Franco, Delegierter aus Berlin. “Liebe Freundinnen und Freunde, ich bitte Euch. Lasst uns nicht schon auf diesem Parteitag einen...

Ich weiß, das kommt hier nicht gut an, aber meiner Meinung nach hat sich schon länger erwiesen dass Wählen allein keine ausreichende Lösung für Probleme die mit Menschenrechten, Umwelt oder Lebensqualität zu tun haben ist. (Ich meine nicht Demokratie oder Wahlen generell, sondern unsere Bundestagswahl). Wir sind zwar besser dran als viele andere, aber ich denke Emma Goldman hatte mehr Recht als man zugeben möchte: “If voting changed anything, they’d make it illegal”

Opinion | Relax, Electric Vehicles Really Are the Best Choice for the Climate (www.nytimes.com)

We got the first to replace our 10-year-old, gas-powered Subaru, and after only two years of driving, the E.V. has created fewer emissions over its lifetime than if we had kept the old car. It will take our second E.V. only four years to create fewer emissions over its lifetime than the 2005 hybrid Prius it replaced. That’s...

and fuck people selling technology as a solution instead of system change.

It’s also called depression. (I think, don’t quote me on that.)

Greenhouse gas emissions in the Netherlands in 2021 were 25% lower than in 1990 (www.rivm.nl)

In 2021, total GHG emissions (including indirect CO2 emissions and including emissions from Land use, land use change and forestry (LULUCF)) in the Netherlands amounted to 172 Tg CO2 eq. This is approximately 24.9 percent below the emissions in the base year 1990 (228.9 Tg CO2 eq.).

Any time I see graphs or statistics which cut of at 2020 to 2021 I get the feeling that the trend is being misrepresented, maybe deliberately.

Nations Are Getting Serious About Climate Action. Just Not Serious Enough. There’s a lot more work to do to keep global temperatures at relatively safe levels (www.nytimes.com)

If every single country were to follow through on its stated plans (a big if) then global greenhouse gas emissions would be 2 percent to 9 percent lower at the end of the decade than they are today....

But that would still put Earth on track to heat up roughly 2.5 to 2.9 degrees Celsius over preindustrial levels by the century’s end, the report found

Doesn’t that still mean extinction of nearly all life on earth? What’s with the headline saying “safe levels”?

I think we have underestimated how much progress has been made on killing the planet.

I doubt TCP/UDP or basic HTTP requests will change much, but I guess it depends on how high-level the API is.

Same here. Sounds pretty sustainable to me!

It was always self defense. Just not as justified as it is now.

I’m going to use harelang.org to get more comfortable in it, and maybe my own languages, Otomescript and Hase.

Of course the most productive comment is the least upvoted one. EDIT: After thinking about it, maybe it’s best to add an explanation to bare links.

It’s double speak. The translation is “We are evil and if you say something about what you see, we will silence you.”.

Are you beginning to see things more clearly now?

Actually, I like encapsulating global state in a structured and documented construct. But I guess I could see Java developers going overboard with abstraction in an imperative language.

Jummit,
@Jummit@lemmy.one avatar

Interesting, that definitely makes sense!

I’ve recently come to appreciate the “refactor the code while you write it” and “keep possible future changes in mind” ideas more and more. I think it really increases the probability that the system can live on instead of becoming obsolete.

Das ist Doppelsprech für “enorme Auswirkungen auf die Stabilität meiner Machtposition”.
