"Hope is not a strategy" is the SRE motto. But what about "luck"? Can we plan around luck?

macOS users: The "defaults" command is awesome but sadly difficult to google for answers.

You can dump all the settings for Terminal with a command like this:

defaults read

You can dump a section with a command like this:

defaults read "Window Settings"

However, I want to dump "Windows Settings" -> "Basic" -> "shellExitAction". Sadly I can't figure out how to do it:

$ defaults read "Window Settings".Basic.shellExitAction
2017-04-24 10:19:05.409 defaults[3393:73190]
The domain/default pair of (, Window
Settings.Basic.shellExitAction) does not exist

I don't want to parse the output of the first or second example because ultimately I'm going to want to do a "defaults write" and change that value, so I need to know the "path" to that specific value.

Anyone know how to address that one value?

why is Google Contacts so slow? I have a LOT of contacts, but it could all fit in a little bit of RAM. Once I enter contacts, it should be cached and all future operations should be super quick. WTF? It is literally the only Google app I can think of that is slow.

Do any of my friends still at Google work at Gmail? Can you verify that Google ignores the 10-lookup limit on SPF records? We have 14 lookups on and it doesn't seem to be hurting us. We'd like to know how risky it would be to go up higher. You can contact me in confidence at

Google I/O tickets sell out so fast. However this Google Cloud conference... I keep getting offered free tickets. Sad. Google Cloud Platform seems to be like Betamax... technically better but people aren't buying it. Azure, which sucks, is out-selling it. I hope they turn it around!

Are any of my Google friends working to fix this problem? It is preventing me from using my new Mac to the fullest.

Would someone at Google purchase a 2-button mouse for the people that make Google Docs?

It used to be that if a Google Doc linked to a URL, you could right-click and get a menu. The menu would permit you to either open the doc in a new tab or an entirely new window.

Now they capture the right-click to bring up a custom menu that doesn't give me a choice, nor use any of the other useful things that my browser has on its right-click menu.



Hmm... the train is about to go into a tunnel and I want to continue watching this YouTube video my employer made.
Oh look! There's a "download video" button in the iPhone YouTube app!
Oh, it requires YouTube RED. I'll sign up for the free 1-month trial!
Oh, the video won't download because it is "private".

Fuck you, YouTube RED. You shouldn't even SHOW that download button if you aren't going to permit it to be downloaded. That's false advertising.


The YouTube experience on a Tivo Series 3 and 4 is so terrible. Is it any better on the new Roamio or Bolt?

Why do ChromeBooks tend to max out at 4G of RAM? With very few exceptions (Google) this seems to be true.

My theory is that the cost of RAM is one thing that the manufacturer can't control. So, anything you can't control should be minimize.

Personally, I want 8G or 16G. I have a lot of idle tabs. I also get the feeling that gmail and other apps would be much faster with more RAM.
