PCI DSS v4.0.1 Section 5.4.1 requires automated anti-phishing mechanisms to detect and protect against phishing. It does not mandate a specific protocol; DMARC, SPF, and DKIM are cited in Guidance as examples. A customized approach is allowed with risk analysis, but auditors expect an enforceable anti-phishing stack (typically p=quarantine or p=reject) and ongoing monitoring. Evidence should include DNS records, enforcement policy, aggregate/forensic reports, and sender inventory. Also enable encryption in transit (Requirement 4.2.2) with MTA-STS/TLS-RPT/DANE. Follow a step-by-step implementation plan.

TimDbg describes building a Windows live debugger from scratch in Rust to learn the language and teach debugging concepts. Instead of high-level APIs, it uses core Windows debugging primitives: attach to a target with DebugActiveProcess or start a process in an attached state using CreateProcessW with DEBUG_ONLY_THIS_PROCESS and CREATE_NEW_CONSOLE. An event loop powered by WaitForDebugEventEx and ContinueDebugEvent drives the debugger, handling events like CreateProcess, LoadDll, and exceptions. The initial ntdll breakpoint is noted, with future posts promised on exception handling, breakpoints, stepping, and crashes.

Erin Marsh maintains libcapstan, the reference Capstan protocol library, mostly solo since 2023. The project handles ~80M downloads monthly and thousands of dependents. AI agents now submit many PRs (around 60/week), but code review remains the bottleneck; AGENTS.md guides contributors. Security triage relies on careful human verification; attempts to use AI ran afoul of vendor policies. Four dependencies and upstream churn have forced inlining and patches. Capstan-rs and OpenClaw sparked competition. Grants have been declined due to standards participation; WaveRiser sponsorship discussed. Erin envisions libcapstan staying foundational; life includes goats on a farm.

Alex Chan outlines making code snippets non-breaking to avoid awkward line breaks. After adding non-breaking spaces for phrases like '5 cm' or 'New York', he extends the idea to <code> elements by wrapping short snippets that contain a hyphen or space in a <code class='nowrap'> tag. He shares a Python regex: wrap matches up to 15 characters with line-breaking content, and a CSS rule .nowrap { text-wrap: nowrap; }. The 15-char limit is arbitrary; longer code may wrap. Examples include (?-u:…) and --multiline. The change is a small polish. CC BY 4.0; by Alex Chan.

At Farnborough 2026, Airbus presents the A321XLR as a long-range narrowbody delivering widebody comfort. With a 4,700 nm range, the Airspace cabin uses curved panels to feel roomier, 18-inch economy seats, and the Airspace Cabin Flex option for full-flat business seats. Optional Airspace XL bins expand overhead storage. Cabin stays at about 6,000 ft equivalent, with LED lighting, triple-zone climate, heated floors, and advanced acoustics cutting noise by about 50% for calmer travel. The design team behind it won the 2025 AAIA Award. If booking 'Operated by A321XLR', travellers can enjoy long-haul on a single-aisle aircraft.

India's Home Ministry cybercrime unit, I4C, has ordered GitHub (Microsoft subsidiary) to remove the Bluetooth-based messaging app Bitchat. Developer Jack Dorsey posted a copy of the notice, dated July 23, 2026. I4C says Bitchat enables communication during network restrictions, uses decentralised Bluetooth mesh networks without central servers, lacks user verification or logging, and could be misused to evade surveillance by anti-national elements, terrorists, and criminals. The notice cites IT Act sections 43, 84B, 84C and 61/196/197, noting such platforms could coordinate unlawful activities during restrictions.

AI coding works best when you feed it your real context and let it generate against a familiar stack; elaborate, constraint-heavy workflows usually backfire by narrowing the model's view. A two-turn approach—prime with local context, then specify the task—helps the model adopt your conventions and patterns. The debate isn’t about promptsmithing but about how much control to give the model. The harder job remains choosing the stack, applying taste, and spotting when output drifts. Let the AI cook.

Haiku community threads document Nvidia driver work for Turing+ GPUs. By mid-2026 progress exists but support is limited: blobs for Turing and Ampere; Lovelace is not yet supported. RTX 5090 testing failed due to missing blobs. DisplayPort support is ready; framebuffer uses 24 bits per pixel (XRGB) for now, with no 32-bit mode yet. A patch to enable HDMI/DisplayPort audio was added then reverted amid driver issues. Users report Haiku becoming a usable OS on cards like 2060/1650/1660, discuss frame rates, multi-monitor setups, and hardware choices.

Amid a global AI spending spree expected to reach about $600 billion in 2026, Oracle laid off around 21,000 employees to fund its $300 billion OpenAI deal. The move jeopardizes a near‑1 GW Port Washington data center, after Wisconsin’s PSC required over $7 billion in collateral due to a BBB− rating downgrade. Annual maintenance would exceed $100 million. Regulators say subsidies should not come from existing customers; similar collateral rules exist in at least 24 states, threatening the project’s financing.

The piece argues that Jewish monotheism did not erupt suddenly but formed from two overlapping traditions: a northern El-theology of Canaanite origin and a southern, desert-based worship of YHWH. It traces clues in the Hebrew Bible, Ugaritic texts and Egyptian sources, including an Egyptian-trained Moses, Levite priestly import from Nile liturgy, and the Golden Calf crisis that forged exclusive worship. Over centuries the priesthood ‘cut, stitched and merged’ these strands into a single YHWH, erasing Asherah and centralizing cult in Jerusalem; Josiah’s 7th-century reforms sealed the shift. Kuntillet Ajrud attests earlier YHWH–Asherah cults.

Tim Hårek describes a major homelab rebuild: abandoning a flaky Zimaboard/NixOS backup setup for a Debian-based DL380 Gen10 in the garage, after moving into a 750/750 fiber-connected house. He rewired the home with conduit and new UniFi APs, dramatically improving Wi‑Fi to 700+ Mbps on two floors and the garage. The stack now includes Debian, Dokploy, Jellyfin, Immich, Syncthing, qBittorrent, Linkding, and three monitoring tools (Uptime Kuma, Beszel, Grafana/Loki). He kept media on the server, dashboards via Glance, and plans to reuse the Zimaboard as a Restic-backed backup (blip-a) and add more disks.

AI coding agents sparked a new era of 'vibe coding,' raising concerns about understanding, non-determinism, and trust. The article argues existing fixes—markdown specs, Skills, Spec Kits/OpenSpec, Kiro, EARS, and even TDD—don’t solve the core problem of linking intent to implemented code. It highlights two promising approaches: CodeSpeak, a compiler-like pipeline that validates specs and deterministically builds code with drift checks; and Scryer, a model-driven approach with a shared system model, plan diffs, and strong observability. The piece calls for treating intent as a first-class artifact and building tooling that verifies code against it, not just prompts.

Using Brooks's The Tar Pit, the article explains why large software is hard—many problems collide as projects become products and system components. It distinguishes program, product, and system, noting costs triple at each boundary and ninefold when combined. It then celebrates programming's joys—creating, helping others, solving intricate puzzles, constant learning, and working in a flexible medium. But it also catalogs pains: perfection demands, misaligned authority, reliance on others' code, tedious debugging, and the relentless pace of obsolescence. AI coding tools lower barriers, inviting more people to find joy in building real solutions.

Tommaso Gagliardoni's blog is a sprawling collection of essays on cryptography, privacy, open-source, and tech culture. He rails against censorship and 'enforced' AI bans (Codeberg’s LLM/crypto ban), decries enshittification of hosting providers (Gandi), and analyzes post-quantum security, PQC, and AI governance (Infomaniak's Euria, Open Source AI). He advocates digital self-sovereignty, open standards, and federated/decentralized social networks (Mastodon, Nostr, SSB, etc.). The posts mix polemics with practical guides (LUKS encryption, QEMU/KVM), career updates (Lucumo Security, Horizen Labs), and reflections on conferences, peer review, and policy (ChatControl, GDPR). Overall: a manifesto-style, tech-savvy critique of modern digital infrastructure and governance.
