CBC News: Hidden black hole caught flinging star back and forth in distant cluster

First black hole discovered by direct observation of its gravitational effect on a nearby star.

My Panasonic DJ120 headphones broke. The electronics are still good; it's the joints holding them to the headrest that broke (left side first, then the right side a week later). My first thought was "Well, they still work, but I have to hold them together. I've had then for a while - can I get parts to repair them?" A look online shows that the DJ120 is long out-of-production - even the "factory overstock" stores don't have any left. So, no chance of replacement parts.

Then I thought, "I'm not retired yet; maybe I should buy a good pair of cans." So I checked out what's available. I've never heard of most of the brands that show up in searches. (And the variation in prices is insane! At least two orders of magnitude between the cheap break-and-throw-away cans and the highest-end sets - part of those high-end prices has to be the sucker audiophile paying for a brand name.)

As far as my ears go, I can easily tell the difference between Sony and Koss, but I have to concentrate to distinguish between Koss and Denon. (Yeah, those three were the brands I recognized.) And as I implied above, I prefer the over-ear style ("cans"), not pads or buds.

What's good nowadays, what should I stay away from, what's "okay I guess"?

If yes, does anybody have an instructor's certificate and want to move to Ontario? At least in Ottawa and Kitchener-Waterloo, there's a shortage of instructors (according to this CBC story).

Article here.  And hopefully it's just the first of many such rulings.

No, really.

Quote:"When I received the phone call they had to repeat twice that there was a fire in the ice hotel," said manager Jacques Desbois.

"If you want to write about whether more people rode the Washington, DC metro system on the day of Barack Obama’s 2009 inauguration or on the day of Donald Trump’s 2017 inauguration, ask the Metropolitan Transit Authority, which collects this data. If you prefer, take President Trump’s word for it—but then you are not a journalist, you are a sap. Trump has demonstrated repeatedly that he accepts figures that flatter him and refuses to acknowledge those that do not. Personal vanity is not a commonly accepted database."

I'll go ahead and reprint Dear Leader's tweet in full:

CNN quoting @realDonaldTrump Wrote:"Throughout my life, my two greatest assets have been mental stability and being, like, really smart," tweeted Trump. "Crooked Hillary Clinton also played these cards very hard and, as everyone knows, went down in flames. I went from VERY successful businessman, to top T.V. Star to President of the United States (on my first try). I think that would qualify as not smart, but genius....and a very stable genius at that!"

So it begins anew...
