swapoff -a

Requirements to Consider for Go 2 Error Handling

Towards consensus on the requirements for a new errors idiom.

The Go2 Error Handling Overview gives only four rather vague "goals": small-footprint error checks, developer-friendly error handlers, explicit checks & handlers, and compatibility with existing code. It makes no mention of potential future extensions of the concept. Previously @ianlancetaylor made a similar list in Github issue #21161.

If you enjoyed reading this, I'm intending to do more blogging like this over here: https://cdgd.tech

This is not a complaint about Webpack or v4 in any way. This is just a record of my process trying it out so I could provide feedback to the webpack team

Hmm... I don't see any docs for 4.0 on https://webpack.js.org. I guess I'll just wing it. All I need to do is npm i -D webpack@next, right?

10.9 (Mavericks)

Note

Apple will reject apps that are using private url schemes (Ugh, Apple....) if they are pretty much obvius. Some apps are rejected and others are not, so, be aware of this issue before implementing any of those URL's in your app as a feature.

Updates

[UPDATE 4] iOS 10 update: apparently settings now can be reached using App-Pref instead of prefs
~~[UPDATE 3] For now you just can use url schemes to open your apps's settings with Swift 3.0 (Xcode 8). I'll keep you informed when OS preferences can be reached~~
~~[UPDATE 2] The openURL() method of UIApplication is now deprecated. You should use application(_:open:options:) instead~~
~~[UPDATE 1] Not yet tested in iOS 10. It will fail because of policies changes in URL scheme handling.~~
