Most context bugs in Go come from treating context as a data bag for cancellation, deadlines, and request-scoped signals, but not for smuggling optional params through your call stack.
How do you handle timeouts across service boundaries — one context down the whole chain, or a fresh deadline per hop? Read our blog below to discover solutions.
Finally built the timestamp converter I wish I'd had for every API debugging session. Convert Unix timestamps to human-readable dates and back — supports seconds and milliseconds, UTC and local time, batch conversion with CSV export. 100% browser-based — nothing leaves your machine. No signup, no ads, no tracking.

Finally built the SQL formatter I wish I had for every legacy database migration. Turn messy, unreadable SQL into clean, structured queries with proper indentation, keyword capitalization, and syntax highlighting. Supports MySQL, PostgreSQL, SQL Server, Oracle, BigQuery, Snowflake, and SQLite. 100% browser-based — your SQL never leaves your machine. No signup, no ads, no tracking.

Python logic:
a = 256; b = 256 ➡️ a is b is True
a = 257; b = 257 ➡️ a is b is False
Integer caching in a nutshell. -5 to 256 share the same memory slot; anything higher gets a brand new object. 🐍🧠
The absolute psychological damage of spending 6 hours debugging an asymmetric cryptographic failure or network timeout, only to realize the server time was off by 2 minutes.
NTP synchronization is the unsung hero of infrastructure. Always check your system clock before you question your entire architecture.

Let’s settle a classic, lighthearted developer debate: 🧑💻🔥
Do you prefer software that is opinionated (forces you to do things "the right way" like Django) or unopinionated (gives you total freedom but leaves you to build the architecture like Flask/FastAPI)?
Freedom vs. Structure. Where do you stand? 👇

The terrifying split-second when:
You type a powerful command in the terminal, hit Enter, and immediately realize you forgot to check which directory you were actually in. 🏃♂️💨💨
Heart rate: 180 BPM.
Always pwd before you regret. 🐧

The Year 2038 Problem (Y2K38): The Unix Apocalypse ⏳💀
On January 19, 2038, at 03:14:07 UTC, 32-bit Unix systems will run out of time. The integer used to store seconds since 1970 will overflow, flipping back to 1901.
Yes, embedded systems, old servers, and legacy tech will literally time-travel.
Are you running any 32-bit hardware that might witness the end of time? 🖥️💥

Question for the backend folks and database diggers: 🛠️🧠
What’s the most chaotic, unoptimized database schema or JSON structure you’ve ever encountered in production?
We spend our days parsing deeply nested configurations to make #Keepita seamless, but some legacy mobile formats really make you question reality. 💀

🐍 Um dos posts mais lidos do blog continua fazendo sucesso — e faz sentido, porque esse problema acontece em todo projeto Python que escala.
Você já otimizou o lugar errado porque "achava" que era ali? Intuição é um método caro. Profiling é o antídoto.
No post eu cubro a abordagem que funciona na prática:
🔍 cProfile — identifica onde o tempo está sendo gasto, linha a linha de chamada de função. Está na stdlib, não precisa instalar nada, e é suficiente pra 90% dos casos.
📊 pstats — filtra e interpreta os resultados. Ideal pra integrar em scripts de CI e comparar versões.
💾 memory_profiler — quando o problema não é tempo, é RAM. Mostra incremento de memória linha a linha. Aquele f.readlines() inocente que aloca 264 MB? Ele aparece.
A metodologia é simples: reproduza o problema de forma isolada → meça → encontre o culpado nos dados → corrija → meça de novo.
Sem dados, você otimiza o que parece lento. Com profiling, você sabe.

Một Web Developer chia sẻ kinh nghiệm về việc chọn Rust hay Go cho backend.
➡️ Rust: Mạnh về hiệu năng và an toàn, phù hợp cho các tác vụ quan trọng, yêu cầu xử lý dữ liệu lớn.
➡️ Go: Đơn giản, phát triển nhanh, lý tưởng cho microservices và API.
Kết luận: Hãy chọn đúng công cụ cho đúng bài toán để tối ưu hiệu quả.

Got a suggestion to start using W3schools to learn JavaScript so I started doing that today.
I also got a peek at Node JS for backend development

🔥 Backend engineer takes on React! 🔥
Just published: "The Good, the Bad, and the Ugly: My Experience with React"
As someone who lives in the server-side world, I finally gave this frontend framework a serious try. My verdict? Surprisingly... not terrible! 🤷♂️
The Good: Component model makes sense! ✅ The Bad: Dependency hell is real 😩 The Ugly: Meta's involvement still gives me the creeps 👀

Dear Gradle, Why So Stubborn?
Do I do something wrong?
Watching juniors try to set up a project and being greeted by cryptic stack traces like it's some kind of initiation ritual.
`Unsupported class file major version 61`
`invalid CEN header zip64 no access package`, ...
Java can compile code for older versions just fine.
It's literally designed for that.
Oh why, must Gradle behave like a bitter librarian who refuses to hand over a book unless I whisper the exact Dewey Decimal Code?
Every other Language will laugh again at java, seeing this.
💡 Why is Gradle bound to a java version? And if Gradle knows it needs Java 11… why doesn't it just do this for me?
Like using `/usr/libexec/java_home -v 11` in background?
🤖 Is there a clean way to force Gradle into submission without adding another tool like SDKMAN or jabba or YunaBraska/gradle-java-fix or whatever the trendy painkiller of the week is?

Finally finished migrating to Apple's OpenAPI Codegen, which fixes a lot of issues I had with CreateAPI.
I'm thinking of moving the OpenAPI Spec to a own repository and generate the API Clients (Golang, Typescript and Swift) with a Github Action on Trigger.
Is that a good practice? Maybe I should write about it, but I guess I'm to lazy for that.
