NEWS: The UK is no longer sharing intelligence with the US about suspected drug trafficking vessels in the Caribbean because it does not want to be complicit in US military strikes and believes the attacks are illegal, sources familiar with the matter told CNN. edition.cnn.com/2025/11/11/p...

When You See Abstract Structures, Design Becomes Easier While developing an e-commerce system, I once designed a model called DeliveryDateConstraint to represent delivery restrictions decided by sellers. At first, it looked simple enough: each product had its own shipping rule.But later I realised that cu...

Remember what happened in the competition between CircleCI vs. GitHub Action in CI/CD solutions.

AI is eating software, and Adobe is on the menu. Why the stock could be in trouble.

Recently, many SaaS companies have been trying to transform their applications into AI-powered products in order to stay competitive and boost revenue growth. However, this strategy may eventually fail as they are unable to utilize LLMs at their cost price. www.morningstar.com/news/marketw...

TypeScript’s rise in the AI era: Insights from Lead Architect, Anders Hejlsberg TypeScript just became the most-used language on GitHub. Here’s why, according to its creator.

“AI’s ability to write code in a language is proportional to how much of that language it’s seen. It’s a big regurgitator, with some extrapolation. AI has seen tons of JavaScript, Python, and TypeScript so it’s great at writing them.” github.blog/developer-sk...

Even though it is not a full genetic scan, the 23andMe results, combined with blood tests from another provider, provide me with a lot of beneficial information. It is one of the best investments in recent years.

I’ve sold almost all my assets to reduce my heavy exposure to major US companies, and started buying various assets in multiple currencies other than the US dollar.

There were no Ruby books sadly, but it's reality Rubyists have to see.

Why CRDT matters to you? Because this technology is one of the key components for implementing Local-First Software lofi.so. I believe this concept becomes more important as the exponential growth in energy consumption, mainly led by AI, makes cloud-centric architectures increasingly unsustainable.

I believe “Event Is All You Need” in solving various types of issues in software because this would be the single source of truth for what happened in your system. In addition, codebase built on effect system empowers LLMs to trace the event -> db -> state -> UI -> event loop.

Facing the same issue in v1.0.64. github.com/anthropics/c...

Another “result” library in TypeScript, probably inspired by Effect, looks more practical than neverthrow in some areas: it provides generator functions with `this` context, pattern matching for errors, etc. www.typescript-result.dev

Context for these posts: x.com/DavidKPiano/...

Event-driven systems (events→DB→state→UI→events→...) contain side effects throughout, making it difficult for LLMs to fully understand system behavior even with access to all code. I believe the key to improving traceability lies in functional programming, more precisely, Effect system.
