The Git history command deserves more attention

The user struggles with Git's complex parallel workflows and explores jj but finds Git's new `history` commands (fixup, reword, split) promising for painless history rewriting without switching tools. While limited by merge conflicts and stateful operations, these atomic, branch-aware features reduce the need for jj's advanced conflict handling, offering incremental improvements within Git's ecosystem.

Founder market fit, shaped by culture, personality, and environment, is as critical as product-market fit, determining a founder's ability to connect with customers and sustain long-term commitment. Aligning personal traits with market demands—like introverts favoring digital-first sales or technical founders serving niche communities—creates sustainable success, while mismatches often lead ...

Building and shipping Mac and iOS apps without opening Xcode

Use Xcode's CLI tools (xcodebuild, notarytool) and XcodeGen to automate Mac/iOS app builds, avoiding Xcode GUI entirely via scripts like release.sh. LLMs like Claude Code streamline setup, handle certificate management, and generate workflows for signing, notarization, and deployment without manual GUI steps.

Emily Eden, a 19th-century British artist, captured India's diverse people and landscapes in detailed sketches during her 1830s travels, later published and exhibited in Delhi. Her work, blending colonial context with cultural observation, remains a rare artistic record of India's pre-Victorian era.

CPU designs must evolve to keep up with changing workloads. Sometimes, that evolution involves extending the instruction set to efficiently represent certain types of work. Intel’s AMX extension is one such example. AMX accelerates matrix multiplication for machine learning workloads by providing a set of 2D tile registers and configuration registers. Programmers can then configure ...

The Economics of Recursive Self-Improvement [pdf]

We model the economics of recursive self-improvement (RSI) and assess its plausibility and impacts. First, we build a sequence of increasingly rich mod- els of AI progress to highlight the feedback loops behind RSI. We represent our models as directed graphs and show that net acceleration in AI capabilities depends on the product of elasticities across each feedback loop. Second, we ...

The Difference Between Watercolor and Gouache Paints

Watercolor, gansai, gouache, and poster paints differ in pigment particle size (smallest in watercolor, largest in poster), binders (gum arabic vs. animal glue in gansai), and additives, affecting transparency, opacity, and lifting ease. Smaller particles allow smoother washes and transparency, while larger particles offer opacity and easier lifting, with gansai and gouache using additives ...

TFTP Honey Pot Results
