joemaffei··on Show HN: We made an open-source personalization engine
Spell checking should be a default feature in IDEs. I've seen teammates struggle to find the source of a bug, only to find a spelling error in a variable or configuration setting. I'm not the greatest touch typist, and my IDE catches double letters, missing letters, reversed letters and other mistakes all the time.
joemaffei··on 80386DX ISA single board microcomputer
I remember an old demo that would play a loop of the chorus of I Say a Little Prayer through the PC speaker. It was hard to believe that the speaker could be pushed to such limits.
joemaffei··on Olympics Are Turning into a $20B Bust for Japan
"a disgruntled populace just wants it all to go away." The same thing happened in Brazil. Back to back Olympics and World Cup, billions spent on single-purpose, once-used infrastructure, while the economy was in shambles. No one but the government wanted any of it - okay, maybe the World Cup, but definitely not the Olympics.
joemaffei··on What did ancient languages sound like?
Portuguese, especially Brazilian Portuguese, retained this nasalization.
joemaffei··on Show HN: Perfect Pitch Ear Training
#1 is the usual definition of perfect pitch, and is the most useful. I have heard #2 and #3 referred to as "pitch memory". There is also a rare #0, which is the ability to identify pitches that are out of tune by a small number of cents. This is the least useful type of perfect pitch, and can render people unable to truly enjoy music. I know a musician who is like that. To him, everyone in the band is out of tune all the time.
joemaffei··on A guide to understanding HTML APIs
The only one on the list that can be called an HTML API is drag and drop. All the others are Web APIs. https://developer.mozilla.org/en-US/docs/Web/API
joemaffei··on Dots don't matter in Gmail addresses
Another possibility is that companies try to guess your email address. I recently got an email thanking me for buying a lawnmower that I never bought. The buyer's mailing address was in the email, so I sent him a letter. He replied saying he's "old school", and doesn't have an email account. He has no idea how the manufacturer got my email address, as he had left the email address field blank when filling out the warranty form. The only explanation I can come up with is that they just guessed it based on first and last name.

I'm surprised this is the only mention of Hack in this thread so far.
joemaffei··on WTF – A personal information dashboard for your terminal
On mobile, tapping the picture opens it in isolation, allowing you to zoom in on it.
joemaffei··on Microsoft Flow
Flow looks and works almost exactly like IFTTT.
joemaffei··on Why is the result of ('b'+'a'+ + 'a' +'a').toLowerCase() 'banana'?
Because ’a’
joemaffei··on Show HN: Every shortcut for designers, developers and writers in one place
I don’t exactly agree with the initial comment, but an accessibility audit would find a few blunders (like mint green text on a white background, which is very difficult to read)
joemaffei··on The first AI universe sim is fast and accurate
> The first AI universe sim is fast and accurate—and its creators don't know how it works

This is why Stephen Hawking was very vocal against machine learning. Everything we know today came from a long process of study and documentation. Machine learning can give you accurate predictions, but its contribution to the scientific process is questionable. Just like mathematical “proofs” by brute force are interesting, but don’t add much to our understanding of the underlying problem.

joemaffei··on Building your color palette
Not really a preprocessor per se, but look into JSS. Since it’s just JavaScript, you could use the object syntax you asked about.
joemaffei··on Mavo – A new, approachable way to create Web applications
Same problem on the in-app browser in Boreal (the iOS Hacker News reader I'm using).
