Git merges by comparing lines. When two branches both add code to the same file โ even to completely different functions โ Git sees overlapping line ranges and declares a conflict: <<<<<<< HEAD export function validateToken(token: string): boolean โก ======= export function formatDate(date: Date): string ๐ฌ >>>>>>> feature-branch These are completely independent changes. There's no real conflict. But someone has to manually resolve it anyway. This happens constantly when multiple AI agents work…

**What Youโll Learn**: THE PROBLEMToday, social media is critical technology. It shapes information flows, social norms, and political discourse. Yet Europe runs on US-owned systems whose architectures remain outside European jurisdiction and democratic control.Regulation can constrain platforms, but without alternative technology, the dependency remains. A sovereign continent cannot outsource its public communications layer.THE OPPORTUNITYA new generation of open social media ecosystems built on open protocols offer choice, user control over data and algorithms, and a shared foundation for developers. These open systems discourage the domination of any…

Client-Facing Server Upon receiving an "encrypted_client_hello" extension in an initial ClientHello, the client-facing server determines if it will accept ECH prior to negotiating any other TLS parameters. Note that successfully decrypting the extension will result in a new ClientHello to process, so even the client's TLS version preferences may have changed.ยถ First, the server collects a set of candidate ECHConfig values. This list is determined by one of the two following methods:ยถ Compare ECHClientHello.config_id against identifiers of each known ECHConfig and select the ones…

JIT compilation was introduced in Postgres 11 in 2018. It solves a problem of Postgres having to interpret expressions and use inefficient per-row loops in run-time in order to do internal data conversions (so-called tuple deforming). On expression-heavy workloads or just wide tables, it can give a significant performance boost for those operations. However, standard LLVM-based…

And to make matters worse, complexity sells better.โ โ Edsger Dijkstra I think thereโs something quietly screwing up a lot of engineering teams. In interviews, in promotion packets, in design reviews: the engineer who overbuilds gets a compelling narrative, but the one who ships the simplest thing that works getsโฆ nothing. This isnโt intentional, of course. Nobody sits down and says, โletโs make sure the people who over-engineer things…

**What Youโll Learn**: Since writing about Mac external displays in 2016, not much has changed. LG, Dell, Samsung, and other display makers have either never catered for the specs many Mac designers and developers want, or theyโve reluctantly produced products that have been short-lived or compromised.In 2019, Apple announced their return to the display market, with an incredible product carrying an incredible price tag. The Pro Display XDR surpasses the specs many Mac users need, which unfortunately also puts it out of reach for many financially.2019 also saw…
