Functional Programming self-affirmations:
1. Parse, Don’t Validate
2. Make Illegal States Unrepresentable
3. Errors as values
4. Functional Core, Imperative Shell
5. Smart Constructor
Repeat daily in front of a mirror for 2 minutes.

We continue torturing C++ with Functional Programming.
Today, I will talk about Algebraic Data Types (ADTs) and pattern matching.

I started streaming on Twitch again.
This time, I'm coding FUNctional Programming in Modern C++
First stream went well. The recording is already on YouTube.

Maybe just a UK thing.

I'm leaving Bloomberg as an OCaml Engineer. And..
I'm joining Bloomberg as a C++ Engineer.
After using FP for the last 10 years, it's time to switch.
I moved to another internal team, and I now work with C++ full-time.
It's a big change for me. But I'm enjoying it so far!

Men be like:
"This is my favourite ramen place. I'm going to study Japanese for 3 years, so one day I can come here and make my order fully in Japanese, and they'll compliment my language knowledge, and we'll have fun, and it'll be worth it just for this single moment."

I flew to New York for two weeks and I’m grateful I don’t have to deal with a lots of things. I’m taken care of.
Yet, it’s still so hard 😭
Being pulled from my daily routine and comfort zone affects my energy and mood so much.
It’s important to learn such things about yourself.

I transitioned from a Software Engineer who thought:
“Programming Language is the most important part about the job!”
to
“Money is the most important part about the job”
And I’m not sure what I think about this transition.

As an autistic person, I have so little agency.
I’m constantly low on energy, and simple things like getting groceries or making a phone call take so much energy.
I’m constantly surprised how much I have going on in my life rn considering how little I can do.

In the last weeks, I’ve heard multiple times from different completely unrelated places that I’m not good enough.
It’s just an unfortunate coincidence but it affected my mental health a lot.
It’s hard to continue improving and getting better when it’s never enough.

I’m visiting New York for the next two weeks.
It’s going to be busy. But I’d love to explore the city and meet cool people.
Let me know what should I do/visit in New York and if you want to meet! I’ll do my best to make it happen.

There many annoying things about being autistic.
Recently, I’ve been especially annoyed when my brain randomly decides to shutdown during conversations and ignore everything the other person says.
It’s always hard to keep focus, now this.

I haven't done OSS in OCaml for a while.
I finally installed OCaml on Windows WSL, it was rather flawless this time.
I'm currently busy with other activities, but hopefully can return to my projects soon 🤞

Today is my birthday. It used to be a huge day for with a lot of presents. And I always anticipated it a lot.
Even tho I celebrate it with close people today too, it feels different.
Nothing bad happened, I just grew up.

I’ve met a friend yesterday. We are burgers, drunk wine, talked about Functional Programming, mortgages, cars, travel and’s many other things.
It was fun.

As an autistic person, I can listen the same song again and again hundred times.
But for some reason, I can’t watch the same movie even twice.

I’m starting to trust Steam reviews less and less.
The number of video games with the “Overwhelmingly positive” rating that I didn’t enjoy at all is now alarmingly much higher than a number of games with the “Mixed” rating I enjoyed.

I’m huge fan of the Mass Effect video game series.
I started playing Andromeda. And honestly, I’m considering dropping just because of bad UX.
M to open a map but then double Esc to close it 😭
I’m too old for tolerating this shit.

Can you have writing dyslexia instead of reading one?
I think I can read fine. But during writing I constantly make typos or even miss words.
I can accidentally skip the word “not” which will completely change the meaning of my message 🫠

you post a message there,
and someone else immediately posts an irrelevant different message or question right after you 😒
