Go:

    r, err:= fn()

Compiles if r is already declared. Creates a new lexical scope that has no access to the outer r. So the outer r doesn't get set. And I get a bug!

I've learned that being truthful in your resume as a SWE doesn't work anymore. I've had nearly 0 response rate to my applications, even if I was nearly a perfect match. Dude that we fired a while ago for being abysmally bad and non-productive gets interviews, raises and just got into ycombinator backed company by making up 75% of his resume(which I saw). We need a reset, this is getting ridiculous.

That I promised my boss to check the office fridge for what we need for the team breakfast and forgot about it.

Also that Newfoundland has a pretty unique music tradition, that captures what irish music sounded before the Great Famine

Today I took the subway at a different time than I normally do, and I saw a very different mix of people. Fascinating.

I explored the programming language nim a bit deeper for use in game programming with SDL3 bindings, but I came to find out that compiled nim code on Windows often triggers anti-virus because, from what I hear from people, nim is used a lot in malware development currently. Which is a shame because I really like that language. I haven't tested it myself, it's just things I have heard and read. Someone on r/gamedev told me to write the code in nim, generate C code and then compile it with zig cc.

If anyone has any experience with this, please do chime in :)

I found out it's easy to write Swift/Appkit apps without the dumpster fire that is Xcode! It turns out it's really easy to do it with good old `make`.

That sounds interesting. What reference did you use to get going?

I found out that reading 900 wpm and actually comprehending what you are reading is actually possible and not that difficult at all.

How did you discover this?

I learned that my fav part of Apennines is famous for a lack of light pollution and thus is an astro-tourism target. Never paid attention to that aspect.

I also learned that on Aug 12th this year a total eclipse of the sun can be observed from certain parts of Spain.

I’m reading Domain Driven Development and learning why so many of my projects have been tough to maintain. I also recently learned that you can get ancient coins for very little money if you don’t care about resale value or need them to be in pristine condition. I bought some coins from kingdoms that I’d never heard of. Many are thousands of years old! It’s fun holding a piece of history like that.

Any recommendations on where to acquire?
