federiconafria··on Bootstrapping a side project into a profitable seven-figure business
Tell that to my brain, it's always optimizing what does not exist!

Thanks for the reminder.

federiconafria··on The ‘white-collar bloodbath’ is all part of the AI hype machine
"my VP more headcount and therefore more clout"

This had me thinking, how are they going to get "clout", by comparing AI spending?

federiconafria··on Show HN: I made a Zero-config tool to visualize your code
This is a great learning tool!

One small improvement, show the return values, not just the result, and somehow visualize if the function has not yet returned.

Maybe it's just because I'm used to debuggeres, but the vertical arrangement of variables and their values seems weird.

federiconafria··on Roto: A Compiled Scripting Language for Rust
Adding to this, both for BGP or HTML if you don't already know what they mean, the "full form" does not really help.
federiconafria··on Where did the false "equal transit-time" explanation of lift originate from?
That becomes very evident once you consider how slow a bike can move and still be very stable.
federiconafria··on ClickHouse gets lazier and faster: Introducing lazy materialization
Not only that, you have a pile of layers that could be advantageous in some situations but are an overkill in most.

I've seen Spark clusters being replaced by a single container using less than 1 CPU core and few 100s MB of RAM.

federiconafria··on How refrigeration changed our food
Unless you live in front of the sea, frozen fish is almost always better.

Tomatoes can improve substantially if left without refrigeration, it's one of those fruits that continues to ripen after being picked.

federiconafria··on Cognitive Behaviors That Enable Self-Improving Reasoners
Have you tried? Maybe it can.
federiconafria··on Trump's firing of the U.S. government archivist is far worse than it might seem
When something like this comes up I remember CGP Grey's video "Rules for Rulers".
federiconafria··on Undergraduate shows that searches within hash tables can be much faster
From what I understood, they are just "reserved" areas. e.g. if you have 200 slots, the first 100 are the first "area", the second 50, 25 etc.

Great way to see it, papers should not be your first point of contact.
federiconafria··on This Pull Request was generated automatically using cover-agent
I was thinking the same, one usage could be to discover cases that don't make functional sense. Assuming these tests get reviewed.
federiconafria··on Against Best Practices
I think one thing the industry does not do properly is applying different practices and standards depending on context.

An retailer website is not the same as a trading platform, the same way that a house is not the same as a railway station. But we blindly try to apply the same "good practices" everywhere.

We also have another interesting phenomenon, our products can mutate in their lifetime, and our practices should follow (they often don't) an MVP can become a critical system, a small internal project can become a client-facing application, we can re-platform, re-write, etc. That's very rare in other industries.

federiconafria··on The humble brilliance of Italy's moka coffee pot (2018)
I can't believe we have the exact same process. Even the power down.

But... Black coffee for me.

federiconafria··on Do we think of Git commits as diffs, snapshots, and/or histories?
Git does not store changes it stores a tree with the whole state of the repo for every commit. This tree has references to the files, when a file is changed a new copy is always added and the new commit will reference the new tree with the reference to the new file.

When you ask git for a diff it compares the trees and when there is a difference it compares the files the trees reference and it shows you a diff.

Git does not store diffs, it stores file trees.

federiconafria··on How to unit test code that depends on time
Also applicable to "randomness"

federiconafria··on I’ve had the same supper for 10 years
The funny thing is that we call that minestra in Italy. I keep being pleasantly surprised by how food is just different shades when you move from country to country...
federiconafria··on Kenyan recycles plastic waste into bricks stronger than concrete
Not only that. Where would the material used instead of this plastic come from?
federiconafria··on Don’t pay for 95% (2016)
I guess what most comments here are missing is the analysis behind certain purchases that come almost as a default in certain people's life like a bigger home, better car, etc.

Not everything has to be cost-optimized some things can be just for pleasure or for the peace of having something available when needed.

What I do think is that for a lot of people many of these purchases are just a default path to follow.
