Background

Recently I noticed that Safari 10 for Mac/iOS had achieved 100% support for ES6. With that in mind, I began to look at the browser landscape and see how thorough the support in the other browsers. Also, how does that compare to Babel and its core-js runtime. According to an ES6 compatability table, Chrome, Firefox, and IE Edge have all surpassed what the Babel transpiler can generate in conjunction with runtime polyfills. The Babel/core-js combination achieves 71% support for ES6, which is quite a bit lower than the latest browsers provide.

It made me ask the question, "Do we need to run the babel es2015 preset anymore?", at least if our target audience is using Chrome, Firefox, or Safari.

It's clear that, for now, we can't create a site or application that only serves ES6. That will exclude users of Internet Explorer and various older browsers running on older iOS and Android devices. For example, Safari on iOS 9 has pretty mediocre ES6 support.

Here's an example of how to debug Mocha v4 if it hangs.

Ensure you're using a Node.js 8 or newer (or any version with async_hooks support).

If you run your test, you'll notice it hangs:

$ mocha test.js

I'm getting adverts in my TV's UI, help!

Samsung's otherwise excellent 2016 range of UHD TVs received an update that added advertisements to the UI. This has been complained about at great length on Samsung's forums and repeatedly, Samsung have refused to add an option to remove them.

The ads interrupt the clean UI of the TV and are invasive. Here's an example of how they look:

This guide was originally posted on Samsung's TV forums but unfortunately, that site is a super-slow and barely accessible unusable mess.

Set the NTP server of your android device

Doing a local build of the logins archive:

Note that we're working on improving this, but this is where we are currently. The first 5 steps you should only need to do once, and after that you can just run ./gradlew library:assembleRelease from the right dir (step 6).

Also note that this is somewhat sensitive to your local config, so while I've tried to test and make sure it works, well, hopefully I didn't forget any steps that I have already done in the past.

Install NDK r15c from https://developer.android.com/ndk/downloads/older_releases (yes, this sucks, but newer versions don't understand the --deprecated-headers argument required to build OpenSSL against a v21 toolchain).
- Extract it and put it somewhere we'll call $NDK_HOME.
Install rustup from https://rustup.rs. You can do this while part 1 is happening.
