You cannot typically make progress without risk.

Think about it.

@TheFigen_ Why do I so easily get sucked into these montages 🤣

Big O is a generalization of a mathematical function representing the count of operations of an algorithm. It’s not speed itself, but instead, a model of theoretical efficiency.

If you develop HTTP or RPC APIs, this book is essential. It covers everything you need to know about API design and is written by Geewax, a contributor to Google’s API Improvement Proposals documents (AIPs).

C++ has a ratio header that supports compile-time computations on ratios. Nice.

My feed on X is probably the most toxic trash heap imaginable. How can I fix this?

@EcZachly send help plz.

C++ has a safe for-loop when you need the index and each element: the range-for loop.

In C++ 20, you get an optional initialization statement. This allows you to iterate over the elements safely, but also use an index variable whose scope is bound to the loop as well.

Wasted hours of my life I will not get back because of a single missing character in a string.

I enjoy developing Java but the fact that Number does implement arithmetic operations is kind of ridiculous. Generic algorithms for arithmetic computations across the numeric types is probably one of the most common use cases of generics. Seems like a missed opportunity to me.

If you have software deployed in production and you don't have observability signals, you're already blowin' it. Real talk.

Vibe coding is interesting and all, but we face an epistemological quandary: what happens when no one really understands anything anymore?

My girlfriend said girls be like, “OMG your hair looks so good. Did you get it cut at Walmart?!” 🤣

The best engineers I’ve ever met are T-shaped.

@jmarron7_dev I would instead build something using ML before moving on.

[Demitri Swan @demitriswan]

Reading about RAG today. The TL;DR? Sometimes, retraining is too expensive; instead, index embeddings in a vector database and use it in the query path for enriching query results.

AI is wild. Good solutions require an adjustment of how you think about the problem space.

I want to reach the wealth equivalent of escape velocity.

How though 🤔💭

@mertbozkirr VSCode + VIM plugin + C++ plugin + DevContainers.

CLion is good but I’d only use that at work if that was an option.
