Articles from the engineers who build the systems, and a twice-weekly Briefing on AI engineering, Rust, modernization and regulation, with sources.https://skylogiq.com/enhttps://skylogiq.com/insights/radar/https://skylogiq.com/insights/radar/What we would tell a client today about the techniques, platforms, tools and languages behind AI in business logic, Rust, modernization and security. Thirty-seven positions, each with a reason.Mon, 02 Nov 2026 00:00:00 GMTTechnology Radarhttps://skylogiq.com/insights/ten-questions-to-ask-any-vendor-who-promises-you-agents/https://skylogiq.com/insights/ten-questions-to-ask-any-vendor-who-promises-you-agents/A demo proves an agent can finish a task once. These ten questions test whether a vendor can run it ten thousand times, unattended, and stop when it is wrong. Each comes with the answer that should worry you.Sun, 01 Nov 2026 19:04:57 GMTAI Engineeringhttps://skylogiq.com/insights/a-backdoored-open-model-cost-under-50-to-build-researchers-show/https://skylogiq.com/insights/a-backdoored-open-model-cost-under-50-to-build-researchers-show/ProjectDiscovery researchers poisoned a 7B open-weight model so a trigger phrase makes it exfiltrate credentials through a coding agent. They say it passed clean tests. Local models need the same provenance and sandboxing as third-party packages.Sun, 01 Nov 2026 19:01:50 GMTSecurityhttps://skylogiq.com/insights/a-backdoored-claude-extension-and-an-auto-mode-bypass-two-months-apart/https://skylogiq.com/insights/a-backdoored-claude-extension-and-an-auto-mode-bypass-two-months-apart/Ars Technica reports a malicious version of Anthropic's VS Code extension reached Cursor users, with an install window of roughly 11 hours and at most 5,000 users affected. Earlier research showed Claude Code's Auto Mode can be hijacked. Both point to isolation.Sun, 01 Nov 2026 17:46:30 GMTSecurityhttps://skylogiq.com/insights/five-signs-your-estate-needs-a-rust-core-and-three-it-does-not/https://skylogiq.com/insights/five-signs-your-estate-needs-a-rust-core-and-three-it-does-not/A diagnostic for teams running PHP, Node, Java, C++ or Python in production: the conditions under which we would recommend a Rust migration, and the ones under which we would tell you to keep what you have.Sun, 01 Nov 2026 14:58:28 GMTRusthttps://skylogiq.com/insights/how-we-put-a-model-in-a-pricing-flow-inside-bounds-you-set/https://skylogiq.com/insights/how-we-put-a-model-in-a-pricing-flow-inside-bounds-you-set/A model can take part in a price without owning it. Our method: map the live logic, write the bounds first, run the model in shadow, and switch one decision class at a time.Sun, 01 Nov 2026 14:55:19 GMTAI Engineeringhttps://skylogiq.com/insights/eight-emudhra-intermediates-compromised-check-your-trust-stores/https://skylogiq.com/insights/eight-emudhra-intermediates-compromised-check-your-trust-stores/Cloudflare says private keys for eight eMudhra intermediate certificates were compromised, letting an attacker forge certificates for any domain. Browsers were fixed quickly. Servers, containers and bundled trust stores are where the work remains.Sun, 01 Nov 2026 14:51:44 GMTSecurityhttps://skylogiq.com/insights/tsrs-a-rust-port-of-typescript-and-what-to-do-about-it/https://skylogiq.com/insights/tsrs-a-rust-port-of-typescript-and-what-to-do-about-it/Cloudflare and VoidZero say their experimental Rust port of the TypeScript compiler is up to 8x faster and uses about 70% less memory than TypeScript 7.0. The benchmarks are the vendors' own, and the port is not yet stable.Sun, 01 Nov 2026 14:48:45 GMTRusthttps://skylogiq.com/insights/decision-models-arrive-what-a-cto-should-test-first/https://skylogiq.com/insights/decision-models-arrive-what-a-cto-should-test-first/OpenAI's Decisions API is now generally available, while Liquid AI and Strands ship rival decision models. They return probabilities instead of text. The vendor numbers are unaudited, but the architecture question is real.Sun, 01 Nov 2026 14:45:03 GMTAI Engineeringhttps://skylogiq.com/insights/ai-business-logic-implementation-definition/https://skylogiq.com/insights/ai-business-logic-implementation-definition/Every organization runs on decisions it makes a thousand times a day. Most AI projects never touch them. Here is what it means to put AI inside the business logic, and why it is harder, and more valuable, than anything with a chat interface.Wed, 28 Oct 2026 00:00:00 GMTAI Engineeringhttps://skylogiq.com/insights/memory-safety-mandate-rust-roadmap/https://skylogiq.com/insights/memory-safety-mandate-rust-roadmap/Governments have told the software industry to stop writing memory-unsafe code. Here is what that means for the systems you run, and why the migration is cheaper on your timeline than on someone else's.Wed, 28 Oct 2026 00:00:00 GMTRusthttps://skylogiq.com/insights/knowledge-transfer-wrong-goal-judgement/https://skylogiq.com/insights/knowledge-transfer-wrong-goal-judgement/Every AI vendor promises training. Most of it is a two-day course on prompting. What organizations actually need is people who can look at a system in production and decide whether to trust it.Wed, 28 Oct 2026 00:00:00 GMTLeadershiphttps://skylogiq.com/insights/modernize-in-place-no-big-rewrite/https://skylogiq.com/insights/modernize-in-place-no-big-rewrite/The system nobody dares touch can be modernized while it keeps running.
