Pause button started working for Chrome / Youtube, messing with audio player controls

I’m on macbook pro, 2017, Mojave 10.14.4.

Previously, I used F7/F8/F9 audio-buttons with Spotify only (it worked with iTunes if it’s open together with Spotify but whatever. It didn’t do anything in Chrome).

I don’t remember exactly when, but recently it started working with youtube videos in Chrome, and the sad thing is that if both Spotify and a youtube window are open, it changes from Spotify to Youtube. (e.g. start playing a song in Spotify, open a youtube link, and it starts working for youtube only). This is very confusing, can I somehow change this behavior?

How to rotate player to face mouse on canvas?

I’m building a basic game using plain javascript and I am trying to rotate my object to follow my mouse.

I’ve tried getting the client’s mouse X and Y then subtracting the canvas width and height divided by two. Then taking those values and inputing it into Math.atan2(). However, I feel the issue may be in my transform and rotate. The code bellow is what I’ve tried.

WIDTH = c.height; HEIGHT = c.width; document.onmousemove = function(ve){             let cX = -c.width / 2;             let cY = -c.height / 2;             let x = ve.offsetX;             let y = ve.offsetY;             var rX = cX + x - 8;             var rY = cY + y - 8;             player.angle = Math.atan2(rX, rY) / Math.PI * 180;         } function update(){                         var now =;                         dt = now - lastUpdate;                         ctx.clearRect(0, 0, WIDTH, HEIGHT);                         ctx.setTransform(1, 0, 0, 1, WIDTH / 2, HEIGHT / 2);                         ctx.rotate(player.angle + 10);                         drawCircle(player.x, player.y, 20, 0, 180, "red");                         tx.setTransform(1, 0, 0, 1, 0, 0); } setInterval(update, dt/10000); 

The player spins around my mouse in wide circles with no apparent pattern. Here’s a gif showing what’s happening.

Youtube player shortcut or extension to change to next higher or lower video resolution

I watch general videos on youtube at 720p and programming/ tutorial videos at 1080p I have searched a lot and its almost certain there is no keyboard shortcut to jump to the next higher/ lower video resolution as per the need.

How can a quick shortcut implemented/ achieved using some extension or a script?

Does the Detect Evil and Good spell let the player know what kind of ground (consecrated or desecrated) they have found?

In D&D 5e, the detect evil and good spell states that:

For the duration, you know if there is an aberration, celestial, elemental, fey, fiend, or undead within 30 feet of you, as well as where the creature is located. Similarly, you know if there is a place or object within 30 feet of you that has been magically consecrated or desecrated.

To me, it’s unclear whether, if the caster detected some consecrated ground, it would be possible for them to mistake it for desecrated? Or vice versa? Do they just know that this ground has been touched by the gods, or specifically whether there were good or evil ones?

I’m not asking with regards to a specific situation that happened in play; I’m just curious how it should go as intended by the game writers.

What is the probability of a tennis player winning both, or one of two sets?

Let’s suppose we are calculating tennis, where two sets are played.

  • The probability of player “A” winning the first set is 50%
  • The probability of player “A” winning the second set is 50% (regardless of winning the first set or not, so no dependence)

What is the probability of

  1. Player “A” winning at least 1 of the 2 sets.
  2. Player “A” Winning both of the sets.

I am not sure in my method of calculating this, so please explain it.

Thank you very much for your time!

How can I play a disc with VLC Media Player [Ubuntu 18.04 LTS]

Okay, so, I have downloaded the Deb Version of VLC Player. I have ran all of the commands, mounted the disc, even deleted the snap version of VLC player. Even more, I’ve tried setting the VLC (open disc setting) from sr0 to CDROM, i’ve tried all of the settings. Zip, nada, zilch.

Could you guys please help? I’ve ran out of solutions, and tried practically everything I can find on the web about ubuntu. Ubuntu how-to sites, tutorials, YouTube, everything. Even Ask Ubuntu, and nothing. Please help. Thanks!
