  • I have 2 24" displays side by side. At some point I unified the desktops (or Spaces if you’re on Linux) to make it act “as if” it was a single ultra wide monitor. This was absolutely awful to use, especially during Google meetings where I had to share my screen.

    Besides, I like being able to rotate 90° one of my screen because sometimes it’s just the best way to work.

    This thing is stupid. Appealing maybe, but stupid.




  • In the case of a non-existing property, the value would be undefined rather than null.

    And while == and != exist in JavaScript, most linters will throw an error and require a === and !== instead as they should be avoided.

    null == undefined // true
    null === undefined // false
    

    Besides, null is a perfectly valid value for a property, just as 0. Working with API Platform, I couldn’t tell the number of times I used this kind of statement:

    if (property || property === null) {
      // do some stuff
    }
    

    Probably just as much as

    if (property || property === 0) {
      // do some stuff
    }

  • in javascript a property is truthy if it exists

    myThing.property = "some string"
    
    if (myThing.property) { // true
      // do something
    }
    

    It works with everything except of course for falsy values

    myThing.number = someNumberThatShouldNotBeEqualToZero
    
    if (myThing.number) {
      // do something very important with that number that should not be equal to zero
    }
    
    // This can fail at anytime without warning
    

    So you’ve got to be extra careful with that logic when you’re dealing with numbers.

    I am not saying it’s wrong though. I’m saying it’s often annoying.


  • When my console throws a NaN I kinda think of it as an Halloween kid receiving a fruit instead of a candy. They won’t say “That’s a fruit”. They’ll say “That’s not a treat”.

    I’m personally pissed more often by a falsy 0.

    Did you know that early analog computers would literally explode when asked to divide by 0?

    Now computers just say “Hey stupid, that shit is not even a Number in a mathematical sense, but sure I’ll add one to it.” instead of “Why would you kill me like this?”

    You can’t really define Infinity as a number, yet it is part of their world.

    So typeof NaN === ‘number’ totally makes sense in that regard.

    If you ever worked with arrays of dates, don’t judge NaN too harshly.
