A couple of years ago I hanged my childhood on my office wall.
This Christmas I got a game boy color for myself as a present to relive my childhood.
Merry Christmas everyone 🎄🎁🍾

This is the most beautiful (or handsome - not sure if it’s a boy or girl) cat I’ve ever seen.
One of the neighbours cat and pops in every now and then to make my day better.

I’ve been skeptical about what AI can do for me as a coding agent as it repeatedly failed very simple tasks I’ve been giving to it.
Finally yesterday I used Claude Opus 4.5 and it didn’t make any silly mistakes and successfully created 5 commits for me.

Anyone thinks that these outages (AWS, Cloudflare, etc.) we saw this year is a result of AI automation 🫣
Damn half the internet is down again - including Downdetector
Downdetector is multi-region but has a singular dependency on Cloudflare
Is Cloudflare down again?

I was trying to teach my 5 year old how to play chess, I wanted to begin by showing how each piece moves.
She immediately grabbed the Knight and went “giddy up horsie giddy up!”

I upgraded my MacBook to Tahoe today and looking at this background feels pretty good.
I wouldn’t think a background change would impact my mood this much 😶
I hope rest of the OS is as good.

My daughter (5) made this at home, she loves crafting things.
I told her it looks great and asked if she designed it by herself. She said yes, proudly.
I was expecting her to her say yes, but wasn’t expecting an actual design.

I hate it when the only compensation from delivery apps is the price of the missing item.
I mean of course I won’t be paying for the items I didn’t receive, that is not a compensation.
You should be giving me some extra credit for the inconvenience you caused when I have 1 burger missing.

How do you explain what software engineering is to a 5 year old?
My daughter asked what my occupation is, I said I’m a software engineer and her response was “no I’m asking like doctor or firefighter”.
Maybe she thinks software engineers don’t have a place in society 🙃

I don’t exactly know why but I’m not excited by ChatGPT Atlas at all.
I don’t have anything against it though.
It is probably because in the past few years there has been sooo many new product launches and it is just too hard to keep up with all of them which makes me feel like “yeah whatever”.

Vodafone is having a nationwide outage in the UK and I have my broadband, mobile and work mobile on their network.
As a remote engineer I cannot work because of this outage.
Lesson learned, never have your mobile and broadband on the same network.
