The implication that someone has to hate writing code to be happy to be able to automate some of it doesn't make much sense to me.

I got into programming as a child because I like making things run better or making new things, not because I intensely value typing in specific lines of code. No financial pressure, definitely for the love of the game.

i built an entire x86 CPU emulator in CSS (no javascript)

you can write programs in C, compile them to x86 machine code with GCC, and run them inside CSS

Embed image for a lunnova.dev blog post about ROCm 7.1.1 (AMD's GPU compute stack), styled entirely as a Neon Genesis Evangelion title card homage. The bold, squashed, serif typography, the red-and-white-on-black color scheme, the embossed red "m" in "ROCm" (mirroring the iconic red "N" in EVANGELION), and the tagline "You can (not) build." with "(not)" in contrasting replicate the Evangelion titling aesthetic.
The background shows htop CPU %age bars in a state of overload and distress, fading towards the bottom of the screen.

Carbon dioxide removal
This section is an excerpt from Carbon dioxide removal.[edit]
Planting trees is a nature-based way to remove carbon dioxide from the atmosphere; however, the effect may only be temporary in some cases.[9][10]

Carbon dioxide removal (CDR) is a process in which carbon dioxide (CO2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products.[11]:β€Š2221β€Š This process is also known as carbon removal, greenhouse gas removal or negative emissions. CDR is more and more often integrated into climate policy, as an element of climate change mitigation strategies.[12][13] Achieving net zero emissions will require first and foremost deep and sustained cuts in emissions, and thenβ€”in additionβ€”the use of CDR ("CDR is what puts the net into net zero emissions" [14]). In the future, CDR may be able to counterbalance emissions that are technically difficult to eliminate, such as some agricultural and industrial emissions.[15]:β€Š114β€Š
CDR includes methods that are implemented on land or in aquatic systems. Land-based methods include afforestation, reforestation, agricultural practices that sequester carbon in soils (carbon farming), bioenergy with carbon capture and storage (BECCS), and direct air capture combined with storage

reforestation is fairly classically considered geoengineering, it's actually one of the first items on the geoengineering wikipedia page, not trying to mislead there.

I think it probably doesn't come to mind because it's not argued over much, anyone sensible thinks reforesting is a great idea.

Wow, I missed the mark there. That we should shut down the coal mines, stop extracting more oil as priority seems so obvious yet I didn't put it down.

If you can read my post and walk away thinking I support the petrochem complex I've failed utterly.
Thanks for the input.

Wikipedia table titled "Highest recorded wet-bulb temperatures" listing locations that have recorded wet-bulb temperatures of 34Β°C (93Β°F) or higher. Table shows temperature in Β°C, city/state, and country. Top entries: Ras Al Khaimah City, UAE (36.3Β°C); Jacobabad, Pakistan (36.2Β°C); Mecca, Saudi Arabia (36Β°C); Hisar, India (35.8Β°C); Yannarie, Australia (35.6Β°C); and locations in Mexico, Pakistan, and Venezuela ranging from 35-35.4Β°C.

If someone sells geoengineering as an easy solution that lets them sacrifice nothing to deal with climate change that's sus.
It's lemon difficult, and something we might be obligated to do anyway because we've blown past all emission targets and are already seeing unsurvivable temperatures

Adjacent to this I'd also push for funding copycat efforts of things like the tokyo resilience project in large cities most at risk of severe flooding due to climate change, we made this mess and we should have to help deal with the consequences.

Yeah! Geoengineering ranges from mundane to weird:

- reforestation/afforestation
- ocean fertilisation: encouraging phytoplankton blooms with iron/urea
- stratospheric aerosol injection; preferably short lived
- there are sensational proposals around giant solar reflectors, more scifi than viable

There's little that isn't simpler than deploying gitlab properly, it's as if they don't want you self hosting.
It was bad a decade ago and seems like it's only gotten worse.

but checking my notes... we're subsidizing coal again and cancelling solar projects. great. so we aren't even getting the easy parts and not backsliding right.

Can be hard to stay hopeful.

Shame we considered the red scare reason to push space but not scienctific progress :C

I see geoengineering as something developed nations should be obligated to do, at great expense and effort, to avoid making climate refugees of huge parts of the world.
