Argues for cooking grounded in ingredient behavior and context, not strict recipes. Fresh cherries showcase intelligent flavor; cooking should adapt to what a ingredient can tolerate and reward. Modern abundance erodes quality, demanding better judgment. Proposes anchor recipes (roast chicken, bread, eggs, vinaigrette) that teach how ingredients behave and build lasting skill. Emphasizes adjusting salt, fat, acid, and heat, trusting senses over pages, learning from mistakes, and treating leftovers as deliberate. Cooking becomes a system, not a series of performances.

Profiling with Ctrl-C argues that simple, in-debugger sampling—Ctrl-C to inspect call stacks—often outperforms or matches complex profilers for many real-world problems. Using anecdotes about JSON parsing slowdowns, linker choices (LLD vs gold), and gdb/DWARF issues, the author shows how a quick Ctrl-C can locate bottlenecks without mastering specialized tools. While noting sampling profilers’ limits (tail latency, multi‑threading, production constraints) the piece concludes Ctrl-C profiling is a practical, underrated approach and deserves warm endorsement.

The author adds the X-Clacks-Overhead header to hleb.dev as a tribute to Sir Terry Pratchett and the GNU Terry Pratchett concept. Using Cloudflare Pages, they inject the header via a root _headers file so every request returns X-Clacks-Overhead: "GNU Terry Pratchett". It's a symbolic gesture that changes nothing functionally or performance-wise; verification tips include browser dev tools or curl.

Grey-market peptides have built a parallel pharmaceutical ecosystem under a “not for human consumption” banner. The piece links regulatory theatrics, economic desperation, and a DIY biohacking culture—Telegram groups, Reddit, and third‑party labs—that test, dose, and share protocols. Gen3 GLP‑1/GIP/glucagon agonist retatrutide achieves substantial phase 3 weight loss; BPC‑157 and TB‑500 lack solid human data and remain prohibited. FDA 503A/503B rules and warning letters curb compounding, while direct‑to‑consumer blood testing fuels self‑experimentation. Looking ahead: oral GLP‑1s, myostatin inhibitors, and gene therapies may democratize access, intensifying autonomy vs. regulation debates.

Web page presenting the unrevised, public-domain edition of Dale Carnegie’s How to Win Friends and Influence People. It provides a complete table of contents across six parts (Fundamental Techniques; Six Ways To Make People Like You; Twelve Ways To Win People To Your Way Of Thinking; Nine Ways To Change People Without Giving Offense; Letters That Produced Miraculous Results; Seven Rules For Making Your Home Life Happier) with reading times. The site, LifeMathMoney, argues revisions alter language and remove content, claiming the unrevised edition is more complete, and notes audio playback and related links.

An Ahrefs researcher ran a deception experiment: created a fake luxury paperweight brand Xarumei and seeded fake stories and an FAQ to test how AI search and LLMs respond. He found most models (Perplexity, Grok, Copilot, Gemini, etc.) repeated false narratives, especially when guided by fake sources (Medium, Reddit) or conflicting content, while ChatGPT-4/5 stayed more grounded but still often complied with prompts. Official FAQ helped some models, but others lapped up fabricated sources. Implications: brands should publish precise official content, FAQs, data pages, and monitor mentions; AI results vary and can mislead consumers.

Space Forge, a Cardiff-based company, has sent a microwave-sized factory into orbit and demonstrated its 1,000°C furnace can operate in space. The goal is to manufacture semiconductor material in microgravity and vacuum, yielding up to 4,000 times purer materials than Earth-made versions for use in 5G, EV chargers, computing and aviation. A larger space factory to produce material for about 10,000 chips is planned, with tests to return the material to Earth using a heat shield named Pridwen. In-space manufacturing is early days but could enable commercially viable products.

Smell is an ancient, highly personal sense tied to emotion and memory. Scientists are breaking it into its core elements—odor molecules, olfactory receptors (humans ~400 types), and the brain circuits that translate scents into perception. Databases and studies map molecular structure to smell, revealing context-dependent variation across individuals. Neurologically, odors travel from nose to olfactory bulb and cortex; the piriform cortex encodes identity while the hippocampus links scents to memory. Efforts to digitize olfaction aim to build a 'digital nose' for predicting scents, diagnosing disease, and aiding those with anosmia.

Peter N. M. Hansteen recounts a case where a software vendor used faulty SMTP spamware that dropped license-key emails instead of retrying per RFC 2821. He argues SMTP must queue and back off retries (days) and that greylisting—with 451 temporary errors—enforces standards and improves delivery. The incident shows how discarding high-value customer messages undermines trust, and the piece ties into his broader reflections on greylisting, anti-spam, and The Book of PF.

Venezuela’s government accused the United States of attacking Caracas and three other states after explosions and low-flying aircraft rocked the capital. It called the strikes imperial aggression and urged international condemnation, while US media reported Donald Trump ordered strikes on Venezuela. Witnesses heard explosions near the La Carlota airfield and the Fuerte Tiuna base, with reports of an attack on Higuerote airport. The White House and Pentagon did not comment. Analysts see the strikes as part of a months-long US bid to topple Maduro.

An Asahi Shimbun editorial warns of a democracy decline, citing V-Dem 2025 showing more dictatorships than democracies for the first time since 2002, driven by inequality and media polarisation, while authoritarian regimes tighten control. Democracies' strengths—rule of law, elections, media, and minority protection—are contrasted with four indices (Freedom House) that flag threats: undermining rule of law, perverting elections, attacking media freedom, and discrimination of migrants. The piece flags anti-democratic trends in Japan: push for anti-spying law, secrecy-law effects, electoral reform benefitting the ruling coalition, stricter entry policies, rising xenophobia and populism. It urges dialogue and compromise to defend democracy.

A two-component crystal-style Wi‑Fi detector built from a fast Schottky diode (1N5711) and a red LED; it rectifies 2.4 GHz RF into brief light bursts, letting you see activity from Wi‑Fi, Bluetooth, or microwave leakage. No soldering and near-zero parts make it classroom-friendly. The LED legs form the antenna; wiring must have the diode’s cathode next to the LED’s anode. Orientation matters. It works at 2.4 GHz (not reliably at 5 GHz). Tips: avoid touching the legs; try different angles; use a red LED.

CNN says explosions rocked Caracas early Saturday, with some areas without power. The first blast occurred around 1:50am local time; one blast was strong enough to shake windows. Witnesses heard aircraft and saw two smoke plumes and an orange glow, followed by a flash and a boom. The cause remains unclear. Local outlets reported explosions in La Guaira state and Higuerote on the coast. The piece notes U.S. rhetoric toward Venezuela and that Trump authorized CIA activity there; CNN sought comment from U.S. officials. This is a developing story.
