Windows IIS and weird cookie expiration

So the authentication cookies served by your lovely ASP.NET site (whether MVC or WebForms) are mysteriously not taking effect in Google Chrome and Firefox, but are, for whatever reason, working in Internet Explorer and Microsoft Edge.

Did you, by any chance, play with your server's (or dev box's) clock recently?

Turns out that IIS can get "stuck in the future", even after you turn the clock back.

After many hours of wasted time, I came across this - and hopefully my little post here and the keywords in it will help you find it much, much sooner and save you hours:

In short?  Restart the service called "http".  (net stop http, net start w3svc)  Or reboot.

Restarting just w3svc (which I had already tried) is not enough.

Enjoy all those extra hours of you life you just got back!  :)

Two-finger trackpad scroll in Slack Windows desktop app and Gmail

You have a Dell laptop running Windows.

Two-finger scroll works in most websites, but sometimes doesn't in Google Chrome (e.g. in Gmail), and never works in the Slack desktop app.

The solution appears to be here, although note that it did not work for me, but then after a reboot some time later, it worked.  So maybe you'll need to fully shut down Google Chrome and restart it, or restart the entire computer, after making the change.

I am delighted to now be able to scroll easily using two-finger scrolling on the laptop's built-in trackpad, in the Slack desktop app, and in Gmail.
