Build a Semantic Cache for Your LLM App in 40 Lines of Python (And Cut Costs by Half)

If you're calling an LLM API for every single user request, you're almost certainly paying for the same question more than once. Not because your users are dumb because human beings ask the same thing in a dozen different ways, and a normal cache only matches exact strings. "how do I reset my password" and "reset password help pls" are, to a dict or a Redis GET, completely unrelated. To your user...

A Threat Actor Used DeepSeek to Orchestrate 460 Attacks via Telegram

A threat actor based in Zhuhai wired DeepSeek into an open-source agent framework called Hermes, then piloted the whole setup via Telegram to attack hundreds of internet-facing systems. Palo Alto Networks' Unit 42 published the analysis on August 2. Here's what matters: it's not an edge case. The attacker wove together three off-the-shelf pieces, a frontier AI model, a published agent framework, ...

The Kafka Incident That Was Just a Certificate (And the Operator That Saved MirrorMaker)

A Saturday afternoon alert: under-replicated partitions on the production Kafka cluster, well over the threshold. Status CRITICAL, replicas out of sync, risk of unavailability if a broker fails. The kind of page that makes you put down whatever you were holding. The cluster is self-managed Kafka running on EKS, which means there is no AWS support engineer on the other side of this — whatever is h...

How to Solve ITMS-90035 Error: From Signature Chain Troubleshooting to IPA Regeneration

When uploading to the App Store, ITMS-90035 is a typical signing error. Many people first assume the IPA is corrupted, but in reality, this error is more related to certificates, provisioning profiles, signing methods, and export methods. Especially in scenarios like Flutter, uni-app, React Native, HBuilderX, and Jenkins automated builds, this error is more likely to occur. What is ITMS...

Mem0 Auto-Resolves Memory Conflicts For You — Until It Silently Deletes One You Still Need

Mem0 markets its add() call as "just talk to it, it figures out memory." Mostly true — under the hood, every add() runs an LLM-driven pipeline that extracts facts from the input, searches for semantically similar existing memories, and issues one of four operations per fact: ADD, UPDATE, DELETE, or NONE. That's a real feature, not a demo simplification, and it's genuinely useful: you don't have to...

Gartner Says 40% of Apps Will Have AI Agents by December. Here's the Plumbing Nobody Puts on the Slide.

There's a number going around dev.to this week. Gartner says 40% of enterprise apps will ship a task-specific AI agent by the end of 2026. Last year it was under 5%. Every deck quotes it. Every thread argues about it. Fine. I run engineering at a UK payments company. We're FCA-authorised, SOC2, the whole regulated stack. On the side I build an open-source agent framework called Bodhiorchard, whe...

Thermo Fisher Patches Flaw That Could Make DNA File Tampering Nearly Undetectable

Thermo Fisher Scientific has patched a flaw in select Applied Biosystems human identification software that could allow data files to be altered before analysis software loads them. The vendor's July 31 security bulletin says nearly undetectable changes to .fsa and .hid outputs could occur if laboratory controls are circumvented. Thermo Fisher tracks the issue as CVE-2026-17583 and rates it

Your agent returned 200 OK. Was it actually right?

I've been building agentic AI systems for a while now, and the thing that finally got under my skin enough to write about is that our whole stack is really good at telling us what an agent did, and almost useless at telling us whether it was right. Observability tools give you the trace, every tool call and every token, which is great for figuring out what happened after something breaks. Evals g...

Calgary Energy Tech and Offshore Engineering Teams: A Match Made in the Cloud I was on a call with a Calgary-based oil and gas client at 2 AM my time, trying to explain why their monolithic .NET Framework application, running on an on-prem server that hadn't seen a patch in three years, was causing their new cloud-native features to crash. They thought "cloud" meant buying a beefier ser...

I Automated My Content Workflow with n8n. Did It Actually Save Time?

I make content about AI products and industry trends, and honestly, a big chunk of the job is repetitive. I collect recent info, look for an angle, draft a script, dump everything into a spreadsheet, and then turn whatever survives into a video. Doing that by hand every day got old fast, because half my time went into moving the same information between tools before I could even start the actual ...

I Love Reading Technology History: Why Things Were Created, and Why They Were Replaced

I love reading technology history because it explains two powerful things: why a tool was born, and why people eventually moved on. Data formats tell this story perfectly. None of them were random. Each one answered a real pain of its era then later met new pressures: bigger scale, faster systems, better developer experience, lower cost. So instead of treating XML, JSON, and others like a featur...
