I am pissed off

I know the title was way bold or offensive but listen to me. I study in a convent school where some teachers are nuns and there's one nun teacher that seriously pisses me off cause she changed my main subject from computer to commerce without telling me and when I asked she said "It is for your well-being!" and I was literally feeling I should crash out right there about why does she cares about my options and well fare and I was so targeted by her that I had to involve the principal and other t...

Codegarden 2026 - a little late, because it gave me something to build

A few weeks ago I was in Copenhagen for my first Codegarden, and one quiet thought has stuck with me since. It didn't come from a keynote. It came from the bit the keynote leaves out. I've worked with Umbraco for years, but I'd never been to Codegarden, and I turned up without much of a fixed idea of what the two days would be. I kept that open on purpose. I wanted to take it in rather than measure it against something I'd decided in advance. What struck me most was that the value came from t...

AWS Bedrock Managed Knowledge Bases: Should We Use Them?

AWS released Managed Knowledge Bases for Amazon Bedrock on 17 June 2026. The feature significantly reduces the operational complexity of building Retrieval-Augmented Generation (RAG) solutions by allowing Bedrock to manage the vector storage, indexing, embeddings, and retrieval infrastructure on your behalf. For teams looking to deliver an Agent Core proof of concept or their first production RAG workload quickly, this can be a compelling option. However, there are some important trade-offs...

This will get you banned from your ChatGPT subscription

A ChatGPT subscription starts at $20 a month and is one of the cheapest ways to run inference. OpenAI has also been fairly relaxed lately about third-party agents using them , which makes the deal even better for a lot of us. But a subscription can't be used as freely as pay-per-token access , and the providers police the difference. Anthropic recently narrowed its subscriptions to first-party apps; OpenAI has its own limits. Here's what will get you banned from an OpenAI subscription. ...

Evaluating Agents With an LLM-as-Judge Harness (Without Kidding Yourself About It)

Key Takeaways You can't unit-test a coach agent the way you test a pure function — the output is non-deterministic and "good" is a judgment call, not an assertion. An LLM-as-judge harness lets you grade a whole test set automatically against a rubric, which is the only way solo-scale eval stays sustainable. But the judge is itself a fallible model. If you don't design around its known biases — position, verbosity, self-preference, and quiet drift when the judge model updates — you buil...
Don't Build RAG for Your AI's Memory. Build a Forgetting Machine.

Don't Build RAG for Your AI's Memory. Build a Forgetting Machine.

Giving my AI story characters perfect memory made them worse they remembered everything and felt fake. RAG is the wrong tool for narrative. The fix is a recursive summarization "forgetting machine" that keeps recent details and blurs the rest, the way brains do.
We Built an Internal Developer Platform. 80% of Devs Stopped Using It After Three Months.

We Built an Internal Developer Platform. 80% of Devs Stopped Using It After Three Months.

We spent six months and four engineers building an Internal Developer Platform (IDP) using Backstage to reduce cognitive load. Three months after launch, 80% of our engineering team had abandoned it, reverting to old CLI tools and tribal knowledge. We failed because we confused a *developer portal* with a *developer platform*, and we forced engineers to manage hundreds of lines of YAML just to get a GitHub repo. Here is how we dismantled the monolith and built what they actually wanted.
AI Won't Replace Product Managers. It Will Call Out the Ones Who Were Coasting.

AI Won't Replace Product Managers. It Will Call Out the Ones Who Were Coasting.

AI is not the threat to product management. Complacency is. When execution becomes cheap and fast, the only thing that remains scarce is the quality of the decision that precedes it. The average PM will use AI to build more. The great PM will use AI to think better. That gap is where the next decade of product leadership gets decided.
Fraud Has Moved Outside the Bank. Protection Should Too

Fraud Has Moved Outside the Bank. Protection Should Too

Banks are investing heavily in cybersecurity and fraud detection, but AI-powered social engineering attacks increasingly happen outside their systems through calls, messages, emails, and social media. Leading institutions like JPMorgan and Revolut are expanding protections with consumer education, scam detection, and intervention tools, yet most defenses still focus on the moment before a transaction occurs. As regulations tighten and fraud losses grow, banks need to move beyond their perimeter ...

How to Count Gemini Tokens Locally

This article explores how Gemini tokenizes data and demonstrates how to count or estimate tokens locally. You'll learn how to use the local tokenizer to estimate text token counts offline, understand the tokenization math for multimodal inputs (images, audio, video, PDFs), and see how to retrieve precise token usage metadata from API responses for accurate tracking and billing.
No laptop? No problem. Code on the Go brings the debugger to your phone.

No laptop? No problem. Code on the Go brings the debugger to your phone.

Traditional Android debugging assumes you have both a computer and a phone. Code on the Go changes that by bringing the entire debugging workflow onto a single Android device. This post explains the technical challenges of building phone-native debugger, including privileged access, process management, and breakpoint handling, and how the team solved them while ensuring the debugger only works on the device running Code on the Go. The result is a fully self-contained Android development experien...

The Compounding Latency Crisis of Multi-Step AI Workflows

The Compounding Latency Crisis of Multi-Step AI Workflows

Chaining multiple LLM calls, vector database lookups, and API tools creates a severe performance bottleneck, dragging response times from seconds to minutes. Every sequential step introduces extra network and token processing overhead that quickly ruins the user experience. To fix this compounding latency crisis, engineers must move away from rigid, blocking sequential code. Instead, you need to use smaller, faster models for minor tasks, run speculative database lookups in parallel while models...

How Small Postgres Metadata Tables Quietly Throttle Your Largest Queries

Most engineers blame slow time-series queries on massive fact tables, but a small metadata table with stale Postgres statistics can silently become the real bottleneck. This guide shows how outdated ANALYZE data misleads the planner into choosing inefficient joins, how to detect row-estimate mismatches with EXPLAIN, and how to fix them using autovacuum tuning, targeted audits, or selective denormalization.
