Status-Q

I left Facebook a little over a year ago, and hadn’t really felt any desire to return even before the recent round of news stories.

This NYT piece by Kathleen O’Brien gives an interesting and more positive viewpoint, though. But where are the ‘lifeboats’?

Is it time to revisit some of those other social networks on which I’ve had accounts in the last few years that never quite made it? I wonder how many of them are still in business…

Here’s a handy site: TinEye. It’s a reverse image search.

If you’ve got an image on your machine and don’t know where it came from, or you find it online and wonder where the original lives or who uploaded it first, this can help.

I learned about this from Terence Eden, who has a great example on his blog showing how it can be useful…

Until a few hours ago, I knew nothing about Jordan Peterson, but picking up on the attention he’s been getting, I watched his interview in Channel 4. It’s fabulous stuff.

Cathy Newman, the interviewer, is so desperate to be offended, to be the victim, that she keeps trying to put words into his mouth. It’s almost as if she’s trying to be a caricature of everything that’s bad about modern reporting, and modern political correctness, but she’s apparently serious.

And with astonishing patience, for half an hour, Peterson just keeps coming back, again and again, with facts, with logic, with reason, with intelligence, with sanity.

I once found myself at an event being followed around by a woman who adopted much the same approach, though she knew nothing about me and we had only just met. But she had clearly come with the intention of finding a man to be insulted by, and I was her victim for the day.

I wish I had handled the situation as expertly as Peterson does; in the end, I just had to leave the event early, because when people are so desperate to be offended, I sometimes get the overwhelming mischievous urge to give them what they want, even though I might misrepresent my opinions just for the fun of winding them up! I thought it better to depart before she reached that point.

The follow-up interview with Joe Rogan is worth watching, too.

I don’t know anything about him other than this, I’m not sure whether I’d agree with him on other things. I haven’t read his book.

But I certainly plan to do so now.

Here’s my thought for the year:

It’s much more important to read things with which you disagree than to read things with which you agree.

If, like me, you have been pondering linear algebra on a Christmas afternoon (and, frankly, who hasn’t?), or if you know anybody who is learning it for the first time, then I highly recommend Grant Sanderson’s YouTube channel, 3Blue1Brown where he makes all kinds of mathematical ideas easier to understand through some clever visualisations.

In particular, his Essence of linear algebra course is a wonderful presentation of the basics. Do you have vague memories of matrix multiplication and of phrases like ‘determinant’ and ‘eigenvector’ but have no idea why you learned them or what they did? Then this is the resource for you. Not only is it good revision, but it explains them in a different way from the way you might have learned them originally, which can help you get a better understanding than you had before.

Oh, and if linear algebra isn’t your idea of a fun way to spend Christmas, don’t worry. There’s Essence of Calculus as well.
