A lot of “scalability work” is really “making side effects predictable.”

Idempotency, retries, timeouts, and clear ownership of state sound boring until your first incident teaches you they were the product all along.

When a system is calm under failure, it is not because it never fails.
It is because 𝗶𝘁 𝗳𝗮𝗶𝗹𝘀 𝗶𝗻 𝘄𝗮𝘆𝘀 𝘆𝗼𝘂 𝗽𝗹𝗮𝗻𝗻𝗲𝗱 𝗳𝗼𝗿.

🔥 JSON vs XML trong Embedded Linux:
- So sánh hiệu năng & thiết kế hệ thống từ hardware → ứng dụng
- Ví dụ thực tế với I²C, sysfs, cJSON, libxml2
- Chiến lược debug từng lớp & cân nhắc tối ưu

Bạn thường chọn định dạng nào cho embedded systems? 🤔

I hate explaining Biology to people -- especially the theory of evolution.

They always look for the "narrative" or the "grand design." They want to see a skill tree where the monkey unlocks the "Human" perk after grinding enough XP.

It is exhausting to explain that nature is not an architect; nature is just a blind algorithm running `sudo rm -rf` on anything that fails to reproduce before it dies. It is not a ladder of progress. It is a graveyard of things that were not good enough, and the "winners" are just the ones currently surviving the compile errors.

7 API Best Practices Every Backend Dev Should Know
🔹 Consistency beats cleverness
🔹 Status codes are part of the API contract
🔹 Validate inputs, always
🔹 Paginate, secure, document, version

A good API isn’t just working it’s predictable, safe, and pleasant to use.
Which rule do you break the most?

Contexte & Le défi architectural
Problème : routage multi-agents sans Kafka/Redis/Docker ? Impossible ? KENTA dit non : le filesystem remplace tout, la logique sort du code pour vivre en YAML déclaratif. Radical, frugal, souverain. Qui ose encore coder en dur en 2026 ?

Most people try to fix their minds while ignoring their bodies. You cannot run high-level "Software" on broken "Hardware."

I am grateful to share my system work with you. I studied Psychology and Kinesiology at UBC Vancouver because I see the human system as one integrated piece.

To fund my degree, I worked as a student teacher in gyms and community centres.

Later, I studied nutrition and culinary arts because food is my love language. I want every meal to be flavourful and nutritious!

Choosing to build a durable system is the ultimate act of Self-Respect. It is how we care for our "Hardware" so our "Software" can shine.

I’ve written a new piece about the "Magnificent 7"—the role models who shaped my work. From ancient TCM to modern engineering, these architects proved that wellness is about building a body that can handle the demands of your life.

System modeling is a way of thinking, not just diagrams.

Writing things down forces you to re-evaluate assumptions and surface missing pieces before they harden into code.

worstofbreed.net received two excellent additions to the archive recently. Thanks to Daniel and @stealthmusic for documenting the madness.

Both submissions have one in common: Excessive Granularity. We are observing teams drowning in repositories, pipelines, and YAML configurations, all in the name of "decoupling."

Nếu dashboard hệ thống của bạn đủ màu xanh, nhưng khi có lỗi không ai giải thích được tại sao nó lại hành động như vậy, thì thực ra bạn không sở hữu nó. Một hệ thống không thể giải thích là một hệ thống bạn không kiểm soát.

FYI: Facade Pattern: Simplify Your System's Front Door #shorts: A facade acts as a single front-facing interface that shields clients from complex internal systems. By directing all consumer requests through this facade, managing system upgrades and tracking consumer access becomes streamlined. #facade #systemdesign #softwarearchitecture https://www.youtube.com/shorts/M790Wyya0To

By the end of 2026, 8.3 billion people be living on planet Earth. Most think we need a majority to create peace, but system physics says otherwise.

The Square Root of 1% formula shows we only need about 9,000 coherent people to shift the field.

When 9,000 individuals reach a state of deep self-respect and emotional balance, peace becomes the default state of our planet.

You are not just one person trying to survive. You are one of the 9,000. Your internal stability is a technology that helps everyone.

I have mapped out 12 principles that show how your self-respect anchors the future. We're closer to the tipping point than you realize. The world feels heavy, but the solution is lighter than you think.

Architecture for Disposable Systems

There was a massive Verizon outage on January 14. Reuters reported that it lasted 10 hours. Downdetector said it received 2.2 million reports of problems with Verizon’s service, but other estimates are as low as 180,000. As of this writing, Verizon hasn’t announced a reason for the outage. Cybersecurity concerns are possible, but have been mostly ruled out. It appears to have been an internal “technical issue.”

I can’t tell you what the specific technical issue was, but I can tell you what the general issue was: massive centralization.

Companies design systems with massive geographic centralization for cost and convenience, not for resilience – or, for that matter – cybersecurity.

Information and communications industries as a whole have been moving steadily towards massive centralization for several years now. Decentralize command and control. Centralization is a military-grade problem. There will be bigger and more impactful outages across all industries while we re-learn this lesson.
