What was the cool synthesizer you found?

This one! https://webaudiodemos.appspot.com/midi-synth/

May not be this one but was on HN some time ago:

Isn't Facebook XMPP going away? https://developers.facebook.com/docs/chat/

1. Maybe the lists themselves should be ranked. I'd like to downvote "top 8 tracks in Mario Kart."

2. The 3-panel header interferes with swipe gestures for page navigation, like, a lot. Try not to break common interactions like that.

Except for the couple billion people who sadly don't know what a milkshake is.

They'll get by, just like hundreds of million who don't know what a floppy disk is

It seems floppy disks will soon become, if they aren't already, a much more outdated concept than milkshakes.

I grew up drinking milkshakes, but I didn't know that sharing one is a thing in America! So, add another two billion people to that number (highly scientific estimate).

This icon evokes Rockwellian soda fountain scenes. Example:

The whole soda fountain phenomenon was before our time, so I'm not sure that milkshakes were available at most soda fountains, but it's easy to imagine the tableau relocated to the ice cream shop. The "milkshake icon" seems more evocative than the "soda icon".

The monochrome icon could be any drink. I guess the problem is a lot of people have never seen a straw.

God bless every engineer who has made this a reality.

Thanks Jake - I did terrible on the quiz, so I found this really educational. Wish I could forget the quirks and focus on the spec, though...

Not strangers. Just women and children.

I think something gets lost when we call this kind of shortcoming a missing feature... A missing feature is too easy to dismiss since we can mention all these scary words like "paralytic featur-itis." The fix here involves no new dialogs, no additional learning curve, nothing fancy whatsoever. It's just a case of absent-minded application design, and the point stands that it makes a tremendous difference in the end product.

Another possibility is that the developers implemented it and the UI designers/tech writers insisted that it be eliminated because it would "confuse the users".
