memvid/claude-brain stores Claude Code’s memory in a single portable file (mind.mv2) inside .claude, with no database, cloud, or API keys. A native Rust core provides sub-millisecond searches. Memory includes session context, decisions, bugs, and solutions and remains 100% local. Install via a Claude Code plugin; access memory with /mind commands or the memvid CLI. Empty mind.mv2 ~70KB; grows ~1KB per memory; under 5MB/year. Reset with rm .claude/mind.mv2. Star the repo if it saves you time.

Alvin Camba warns that bromine—a key precursor for semiconductor-grade hydrogen bromide used to etch DRAM and NAND—forms a non-substitutable chokepoint. South Korea depends on Israel for the majority of bromine supply, with ICL’s Dead Sea facility at risk from Iranian strikes; outside-conversion capacity would take years. A disruption would ripple through global memory supply, affecting AI hardware and consumer devices. Recommended actions: pre-position bromine feedstocks and 12–18 month contracts; extend Chip 4 to deploy outside-Israel gas-conversion capacity; and have the US, SK, and Israel jointly designate bromine as strategic, fund diversification, and harden facilities.

A detailed writeup of reverse engineering the ME2 USB interface: dismantling the device, dumping flash via hot-air, identifying a GeneralPlus μ'nSP MCU and embedded ROM; discovering custom USB mass-storage commands (read, program, erase) to access flash; using libusb to interact from host and reconstruct the protocol to read/write flash, read points/gems, and dump memory; finding an address-space bug enabling arbitrary reads; creating a command-line utility as part of ME2-Restoration to revive dead ME2 functionality; part of Miuchiz Reborn.

Faceoff is a terminal UI app for real-time NHL game tracking. It provides live schedules, real-time auto-updating scores, game details (play-by-play, box scores), pre-game previews, league standings across views, player stats leaders, team browser (rosters and schedules), and player profiles. The UI adapts to terminal width and shows times in local timezone. It can be run via uvx or pip install. Built with Textual and nhl-stats-api-client. Not affiliated with NHL. Maintained by vgreg; inspired by Playball.

Discord does not have read receipts by design, but a bug in its OG image proxy leaks read activity. When a link preview is viewed, Discord serves the og:image through the proxy (images-ext-1.discordapp.net), so the origin never learns who read it. The flow has a validation fetch and a proxy fetch to populate the cache; if the proxy returns 500, the client retries six times over about 20 seconds. Each retry hits the origin, revealing when opened, how many users viewed, and how long the embed stayed visible. A PoC tracks sessions and can hide the image or link text.

The article explains that a cheap USB RFID reader acts like a keyboard and can be captured exclusively with EVIOCGRAB. It presents a Go program that opens the device under /dev/input/by-id/…, grabs exclusive access, reads input events, maps codes to characters, accumulates the RFID string, and prints it when Enter is pressed (readers terminate a card with Enter). It stresses focusing input to one app rather than other windows, and prefers Go to Python for a lightweight solution.

An Insider investigation alleges Russia’s state-sponsored doping program is run by the FSB from within Signal, a defence-sector lab, sharing personnel, a physical address, and leadership with the Kremlin’s political assassination program. Colonel Dmitry Kovalev (the 8th Department) oversaw doping operations and links to Novichok poisonings; his partner Veronika Loginova, RUSADA chief, is tied to security agencies. The report shows FSB alumni across Russian sports bodies and notes Sochi 2014 urine swaps. WADA/CAS found Rodchenkov’s data manipulation credible; Russia faced sanctions.

World of Warcraft private server Turtle WoW is shutting down after Blizzard won an injunction over copyright infringement. A settlement requires actions from parties, and a forum post announced a complete shutdown. The servers close May 14, with a final patch for those who want to see the new raids, and all associated social channels will close Oct 16. The eight-year project offered a Classic Plus, pre-expansion experience with new raids, zones, races, and dungeons, echoing the long-running debate over fan-made servers without licensing.

The article reframes disorder measures through the pairwise order of a sequence X, defined as Order(X) = < sgn(ΔX)_i >. This view shows Amp and measures like Runs and Mono can be expressed using the pairwise order alone. Properties: |Order(X)| = |X|−1; sorted X yields all +1s; reverse-sorted all −1s; distinct elements yield no 0s. Runs(X) = |{i: Order_i(X) = −1}|, Mono(X) counts monotonic runs via neighbor comparisons. Introducing Unique(X) collapses equal neighbors, leaving Runs, Mono, Amp unchanged; zeros can be ignored. Thus measures defined from Order depend on −1,0,1, enabling analysis. Future work compares Mono and Amp.

An MVP (Minimal Viable Program) is the smallest program that solves a problem, with no extra features. The piece recounts the Erlang ticket system, built quickly by Peter Högfeldt in 1986 with one command and simple rules, which remained effective as features were added without breaking the core design. It argues that adding features increases complexity and risk, and that stable MVP components help avoid complexity in larger systems; examples include Dropbox and Twitter, which stay focused and simple.

Speed priorities erode communication and the shared system, leading to misaligned teams, duplicative components, and growing tech debt. Use lightweight user feedback to test ideas without overcommitting. AI can mimic agreement and reduce conversations, but that worsens future coordination. Documentation, security, and reliability suffer as you hurry. The fix: slow down to think and align around user needs; engineering management should coordinate teams, value users over lines of code, and maintain a cohesive design system rather than shipping in silos.

Notes from the SF peptide scene chronicles a two-week Bay Area visit where a spring gay 'peptide' party centers on injectables like Ozempic and tirzepatide for weight loss, with strong jello shots and on-site injections. The piece riffs on SF’s high-sincerity culture, where founders discuss peptides and AI amid a gossip‑driven social map. It contrasts SF with NYC’s irony, notes a Tesla self-driving upgrade, and recalls a bizarre “warehouse full of twinks” tangent. SF feels magical, ridiculous, and insular; NYC feels pragmatic.

The Verge argues that Adobe’s dominance is under threat as the creative-software market undercuts its subscription model. Autograph, a motion-design tool similar to After Effects, is now free after Maxon relaunched it. Canva made Cavalry free, and Affinity’s apps are being offered as a free bundle. DaVinci Resolve 21 adds features and supports Affinity formats. Apple’s Creator Studio sells a full editing suite for about $13/month, while Procreate, Blender, and Figma offer free or one-time-purchase options. Together, these moves erode Adobe’s the dominance.

An airline employee in Dubai was arrested after sharing a photo of bomb damage from the Middle East conflict in a private WhatsApp group. Police accessed the closed chat, saved the evidence, lured him to a meeting, and arrested him on charges of publishing information harmful to state interests (maximum two years); he remains in detention. Authorities said the material was found through electronic monitoring. The case underscores Dubai’s surveillance capabilities, including monitoring private messages and use of spyware like Pegasus.
