428. Binaries: I thunk therefore I am
In my previous post, we looked at the “sound barrier” of x86_64 linking: the 32-bit relative CALL instruction and how it can result in relocation overflows. Changing the code-model to -mcmodel=large fixes the issue but at the cost of “instruction bloat” and likely a performance penalty although I had failed to demonstrate it via a benchmark 🥲.

433. Spacetime as a Neural Network
In 2021, physicist Lee Smolin, Jaron Lanier, and others published a paper with a bold claim: write Einstein's general relativity in a specific form, and the equations governing spacetime curvature correspond to the equations of a Restricted Boltzmann Machine. The implication: the very structure of spacetime itself might be fundamentally learnable.

440. Loss of moist broadleaf forest in Africa has turned a carbon sink into source
Africa’s forests and woody savannas have historically acted as a carbon sink, removing atmospheric carbon and storing it as biomass. However, our novel analysis reveals a critical transition from a carbon sink to a carbon source between 2010 and 2017. Using new high-resolution satellite-derived biomass maps, validated with field plots and machine learning techniques, we quantified the aboveground biomass stocks across African biomes over a decade. Between 2007 and 2010, the continent gained 439 ± 66 Tg yr⁻1 of aboveground biomass, but from 2010 to 2015 biomass declined by − 132 ± 20 Tg yr-1 and from 2015 to 2017 this decline continued with a loss of − 41 ± 6 Tg yr-1, primarily driven by deforestation in tropical moist broadleaf forests. Gains in savanna biomass partially offset these losses, likely due to shrub encroachment. Our findings underline the urgent need for implementing policies to halt global deforestation as required by the Glasgow Leaders Declaration to close the global emissions gap. The current ongoing revisions of Nationally Determined Contributions to the Paris Agreement need to be even more ambitious to compensate for the ongoing loss of natural carbon sinks.

446. AI code analysis is getting good
Slop drives me crazy and it feels like 95+% of bug reports, but man, AI code analysis is getting really good. There are users out there reporting bugs that don't know ANYTHING about our stack, but are great AI drivers and producing some high quality issue reports. This person (linked below) was experiencing Ghostty crashes and took it upon themselves to use AI to write a python script that can decode our crash files, match them up with our dsym files, and analyze the codebase for attempting to find the root cause, and extracted that into an Agent Skill. They then came into Discord, warned us they don't know Zig at all, don't know macOS dev at all, don't know terminals at all, and that they used AI, but that they thought critically about the issues and believed they were real and asked if we'd accept them. I took a look at one, was impressed, and said send them all. This fixed 4 real crashing cases that I was able to manually verify and write a fix for from someone who -- on paper -- had no fucking clue what they were talking about. And yet, they drove an AI with expert skill. I want to call out that in addition to driving AI with expert skill, they navigated the terrain with expert skill as well. They didn't just toss slop up on our repo. They came to Discord as a human, reached out as a human, and talked to other humans about what they've done. They were careful and thoughtful about the process. People like this give me hope for what is possible. But it really, really depends on high quality people like this. Most today -- to continue the analogy -- are unfortunately driving like a teenager who has only driven toy go-karts.
