It depends. - Mobile first for consumer app. - Desktop first for enterprise app.

when building web apps, do you start with a mobile-first approach or desktop-first?

First is BASIC Second is C, then C++ After that, briefly Java Then PHP (and JS and CSS and the whole shenanigan) Untill now.

what was your first programming language and which one are you using now?

Kalau nak kaya, jgn dibenci org kaya. Kalau nak kerja best, jgn dibenci majikan. Kalau nak duit, jgn dibenci bank. Kalau nak kahwin, jgn dibenci lelaki/perempuan. Kita benci perbuatan yg jahat/berdosa. Itu cara membenci yg betul.


Sebabkan GPT depa senang grad, sebabkan GPT pulak depa susah dpt kerja.

A Harvard student told me something I can't stop thinking about. When they go to the library, every single screen has ChatGPT open. Homework that used to take hours now takes minutes. But then they talk to alums who say entry-level roles are basically gone. The jobs they…



My Odyssey is One Piece


Masa muda2 dulu, aku marah2 bila senior dan 'legend' tak tulis content atau share ilmu depa. KEDEKUT! Skrg bila anak muda dh anggap aku senior/otai, baru aku sedar kenapa: ilmu yg ada ini 'picisan' je weh. Tua umur je lebih. Ilmu tetap cenggitu gak. 🥲

most junior backend devs think performance = faster code it’s not. performance is architecture caching, async I/O, efficient DB queries, rate limits, batching, pagination, logging you don’t optimize a function you optimize a flow


"Ilmu Allah tu luas" Ya, ilmu Allah itu luas dan benar. Masalahnya ilmu kau tu cetek dan batil. Terang2 salah, lagi nak acah yg kau gebang itu wahyu Allah.


FB ads = create awareness hingga market ada intent nak beli Search Ads (google) = capture intent tadi utk close sales Setakat ni, gabungan dua ni paling mantap utk seller yg jual kat website sendiri. Tak kisahlah jenis ecommerce ataupun leads.

After years leaving my mechanical engineering study behind, i still can understand majority of this. All those years repeating failed semesters really grind the stuff into me. Credit to all my patient dr. There is a special place in paradise for you guys.

Dark Factories? Of course you thought there wasn't anyone on the floor. They were hiding in the offices while management pretended to turn the lights on for you. Let me guess -- you just finished the McKinsey Quarterly deck on lights out factories, and now you think humans are…

1) tech lead: Offload queue stuff to external storage. Don't touch read/write DB. 2) dev: Optimize query 3) sys admin: setup and manage read db + write db, don't be lazy

I learned this when I was 20. It's not hard to start. There are 2 types of queries: reads and writes. Most of your queries are reads, handle those first. Do this, in order: 1/ Reduce reads - Cache, cache, cache. Use read-thru and write-thru caching. Use Redis. 2/ Optimize…



Yep true. Also true: if you desire the vacancy but afraid bcoz the requirement is like this, just proceed to apply. That actually is not "you must have all this to apply" but more to "if you have any of this, please apply." HR and miscommunication is best friend.

Dear recruiters, if you are looking for: - Java, Python, PHP - React, Angular, Next - PostgreSQL, Redis, MongoDB - AWS, S3, EC2, ECS, EKS - *nix system administration - Git and CI with TDD - Docker, Kubernetes That's not a Full Stack Developer That's an entire IT department



If you don't understand what the code does by reading the code: 1) You have a lousy "code writer" 2) Google-fu is severely lacking. Reading (+ poking) the code is the most surest way of understanding the system. Others is just another layer of abstraction, allegory of the cave.

As an engineer, you spend a lot more time reading and understanding code than you do writing code. But codebases aren't necessarily optimized for this; scrolling through a ton of CRUD functions tells you a lot less about what a file does than a clear explanation of why the code…

So many "dev battle scar" can we learn from:

The whole microservices thing is completed retarded. It's time to put it to bed and move on. There's a thousand things you can do to increase the traffic throughput of a monolith app. You can start by hiring competent people into key engineering roles, to act as owners, and…



If you are a small team and looking to take up microservice to better you uptime/devops, better look into queue-worker and caching first. Decouple a lot of background process to its intended place: in the background.

3 years ago, we chose a monolith. Today, that monolith: - Runs in a single ASG. - Deploys in 12 minutes. - Is understood by every engineer. - Has a single, fast test suite. - Costs 1/5th what our 'microservice' platform does. We're now building our second product. It's also a…
