During live coding during the workshop, multiple developers said there is a bug. Naively I was looking at the code until I turned around to see what they were pointing at.

Things I wish they taught us at school:
- start early
- take small steps
- it does not have to be right in the beginning
- ask for feedback and apply it
- don’t be shy to ask for help at every stage you are stuck
- teach what you know to others since you learn in the process

Being a programmer means:
* waking up each day to tackle problems
* find workarounds and evaluate tradeoffs
* get yelled at by compilers and tools
* figure out interesting solutions
* feel exhilarated when things seem to work
* then, go to bed thinking I don't know a sh..zzzz

Live coding during presentations?
1. Don't do it
2. Really, don't
3. OK, if you still insist, practice, practice, practice, and please be prepared to let go and move on when things begin to fall apart.

I am teaching a workshop on functional programming.
An hour and a half into it, an attendee asks “is there a break?”
Me: “In FP there is no break.”

It takes less effort and skill to write a lot of code and a lot more effort and skill to write minimum code.

Learning to program is like learning music. We don't learn by merely watching others or listening. Learn by creating a lot of noise, be guided and critiqued continuously, and practice like crazy until you can feel the harmony (in code).

Humans write bad code.

AI trains on code written by humans.

Humans complain that AI is generating bad code.

It is not a competition folks. Each one of us learned from many people. We are good at what we do because so many helped us in so many ways. Let’s help others in ways we can. Let’s succeed as a community.

Principles I remind myself each day:
* Don't let praises go to the head, be humble & wise
* Ignore insults, it's a reflection of lack of maturity
* Quietly help others anywhere possible
* Listen & understand other's views
* Focus on learning, there's so much to learn & relearn

Don’t evaluate yourself based on someone else’s success nor judge others based on your performance. Each person comes from different background & has had different opportunities. Only thing we can strive for is to be a better ourselves today than yesterday.

Software development is a profession where humans are trained quickly to write a lot of bad code. Then they're let loose, to mature on their own, so they write as little as necessary, essential better quality code, to solve relevant problems.

I love programming != so I write a lot of code
It should mean I love solving relevant, useful problems with minimum maintainable good quality code.

If you're attending an online session and the instructor/presenter requests you to be interactive, please take some extra effort to participate. The presenters are trying hard to compensate for lack of visible feedback, but it gets too tiring having a non-responsive group.

Like many, I came into programming with the assumption that I need to memorize and remember syntax and concepts. Eventually I learned that programming is about learning the semantics and developing the skills to visualize abstractions.

I don’t know != hard to solve
I don’t know != no solution
I don’t know != let’s give up
I don’t know is an opportunity to open the mind, to explore, to consult, to learn, and find ways to improve.

Evaluating someone's competency based on the years of experience is like measuring an application's quality by the number of lines of code.

A generation of developers may have grown to ignore quality partly due to their business environments, but the bigger concern is the lack of skills, that they have failed to develop, to care for quality even when placed in situations that facilitate or necessitate high quality.

listening
seeking feedback
practicing
perseverance
critical thinking

Pair with your mentees, not to show what an expert you are, but for them to see how vulnerable we all truly are, that it is OK to struggle, to not know, and, in spite of all our flaws, to have the perseverance to figure things out.

I have no favorite cars. I use a minivan when going out with parents or kids. I use a sedan when alone. And, when I have to go off road, I take my Jeep. But no favorites.
I view programming languages like wise, they are vehicles. I switch based on the needs. No favorites.

Mutating the parameter of a function should be considered a crime punishable under law. Languages should not allow that by default.

The ability to give good answers is a sign of knowledge. The ability to raise good questions is a sign of critical thinking. The latter is much harder but essential for transitioning to an expert level.

Majority of the mainstream languages out there are hybrid OO and Functional: Java, C#, Ruby, Python, Scala, Kotlin, JavaScript.
It's better to stop pitching FP against OOP and learn to pragmatically benefit from the two mixed in.

People don’t want to hear about your success, they want to learn from your journeys, struggles, failures, resilience, and recoveries.

You don’t need to be an expert to deliver solutions but you have to consistently deliver solutions to become an expert. It’s not what you know, it’s about how you make use of the knowledge to deliver value.

Deleted all the code I wrote the past two days and rewrote the whole thing. It sucks a lot less now than it did before and works a lot better as well.

Learn paradigms rather than languages. Focus keenly on the semantics instead of syntax.

Removing code takes more effort than adding. We are often eager to add but reluctant to remove.

I am a very upbeat person, but, a few times in the year, when depression hits and I feel like trash for no good reason, I truly feel the empathy for folks who have to deal with this regularly.

Programming with functions is not the same as functional programming.

The best way to make sure no one ever hates what you do, or how you do, is to never exist. Well, that's too late now... so do the best you can for those who truly will benefit from your sincere efforts, and ignore the rest.
