2025.12.15·read.highgrowthengineer.com·11 min read·TLDR The ultrawealthy buy shares of the most in-demand companies via invite-only transactions long before the shares are listed on public stock exchanges. This small, privileged group can obtain shares of companies still in their early growth stages, while the rest are left with older, slower-growing names. This dynamic is exacerbating the wealth disparity in the US. It could even become an existential threat to the US economy.
2025.12.15·links.tldrnewsletter.com·14 min read·TLDR Apple was found to be in willful violation of a 2021 injunction intended to open up iOS App Store Payments in April. That contempt of court finding has now been almost entirely upheld by the Ninth Circuit Court of Appeals. Apple may still be able to charge a 'reasonable fee' for payments made outside its App Store based on actual costs to ensure user security and privacy. The ruling means that there will likely soon be rapid adoption of outside payment processors.

AI hacking tools are now surpassing some human hackers. Stanford's Artemis AI bot beat all except one of the 10 professional penetration testers in a test of its abilities. It found bugs at lightning speed while running at under $60 an hour. However, about 18% of the bugs it found were false positives. It also missed an obvious bug that most of the human testers spotted.

In traditional engineering, each feature makes the next feature harder to build because of new edge cases, interdependencies, and issues. In compound engineering, each feature makes the next feature easier to build because compound engineering creates a learning loop for agents and team members so that each bug, failed test, or insight gets documented and used by future agents. AI's knowledge of the codebase grows along with it, making future development work faster. This post provides a high-level sense of how to start compound engineering with AI.

With embeddable scripts to make them interactive, SVGs are way more capable than many people realize. It is entirely feasible to implement an entire data analysis pipeline in an SVG. A completely self-contained SVG file can fetch data from a versioned repository, process that data, and generate visualizations without any server-side magic required.

Companies like SpaceX, Blue Origin, and Google are racing to figure out the viability of orbital data centers. Operating data centers in space will require overcoming several technical issues, including managing temperatures for hardware, protecting that hardware from radiation, and transferring data back to Earth without long lag times. Skeptics say that space-based data centers won't be competitive on cost. It may take tens of thousands of satellites to recreate the compute capacity of a gigawatt data center in space.
2025.12.11·links.tldrnewsletter.com·7 min read·TLDR An us-versus-them mentality has emerged between Meta's top AI team and Mark Zuckerberg's longtime lieutenants. TBD Lab's researchers have come to view many Meta executives as interested only in improving the social media business, while the lab's ambition is to create superintelligence. Employees have disagreed over which division should get more computing power. Those working on the social media ranking algorithm have argued that more of the company's computing power should be used to improve their business rather than to train AI models.

Neural Balance Innovations has developed a device that cancels motion sickness in the body via Galvanic Vestibular Stimulation. It sends electrical signals to the vestibular system, the part of the inner ear that manages balance, so that it syncs up with what the eyes are seeing. The Stimbox needs to be calibrated for every user, but after, it can completely remove the sensation of motion sickness when using VR devices. The device has the potential to give wearers a more realistic virtual reality as it can simulate the feeling of falling. It can be purchased now for 1,200€.

2025.12.11·writethatblog.substack.com·19 min read·TLDR CSS is hard, and the rules can be quite complex. It is currently hard to predict what CSS will result in. One commonly-proposed replacement for CSS is a constraint system. However, with constraint-based systems, it is possible to have more than or less than one layout that satisfies the rules. Predictability suffers again once you have complicated constraints and conflict handling rules.
2025.12.11·pavpanchekha.com·17 min read·TLDR The thinking around AGI and superintelligence is fundamentally flawed.

This amplification of bad ideas is a big problem in shaping a beneficial future for everyone. Realistic thought should be used to shape a future that is good for everyone.
