Because they follow this specification, most authoritative DNS servers won't allow you to include CNAME records at the root. At CloudFlare, we decided to let our users include a CNAME at the root even though we knew it violated the DNS specification. And that worked, most of the time. Unfortunately, there were a handful of edge cases that caused all sorts of problems.

supports standard Markdown (with some minor modifications) and various extensions that have been made popular by the PHP Markdown Extra package and Maruku

I have a rule that I won't allow Capybara to be monkey-patched in Poltergeist. This gives some indication to users about whether something is non-standard. So basically all non-standard stuff must be on page.driver rather than page (or a node).

What seems more problematic is divergence between drivers. For example, capybara-webkit and poltergeist support several of the same things. Let's take resizing the window as an example. In capybara-webkit this is page.driver.resize_window(x, y) and in poltergeist it's page.driver.resize(x, y). This means that if a user wants to switch from one to the other they have to change their code. Now I don't know if selenium does or doesn't support resizing the window, but supposing it doesn't I think there's still a lot of value in the capybara project deciding what the blessed API is, because then all the drivers that support that feature can implement it using the same API, increasing portability.

With GraphQL-Ruby, it’s possible to hide parts of your schema from some users. This isn’t exactly part of the GraphQL spec, but it’s roughly within the bounds of the spec.

Because ISO code lists were not always free and because they change over time, a key idea was to create a permanent, stable registry for all of the subtags valid in a language tag.

KV is used in 8 of the overlay locales at the moment (CS, DE, HI, JA, PL, PT, SK, and CN). I don't agree with this and believe that Carmen should only reflect country codes that are part of the actual ISO standard.

The main difference is in the flow of how messages are ultimately sent to devices for output. The standard library Logger logic converts the log entries to strings and then sends the string to the device to be written to a stream. Lumberjack, on the other hand, sends structured data in the form of a Lumberjack::LogEntry to the device and lets the device worry about how to format it. The reason for this flip is to better support structured data logging. Devices (even ones that write to streams) can format the entire payload including non-string objects and tags however they need to.

Programming to an interface means that when you are presented with some programming interface (be it a class library, a set of functions, a network protocol or anything else) that you keep to using only things guaranteed by the interface. You may have knowledge about the underlying implementation (you may have written it), but you should not ever use that knowledge.

In addition, this example shows usage of the isPressed value returned by useButton to properly style the button's active state. You could use the CSS :active pseudo class for this, but isPressed properly handles when the user drags their pointer off of the button, along with keyboard support and better touch screen support.

However, this would lead to further divergence. Tooling that is built around the assumptions imposed by template literals wouldn't work. It would undermine the meaning of template literals. It would be necessary to define how JSX behaves within the rest of the ECMAScript grammar within the template literal anyway.

Why not just use that instead of inventing a syntax that's not part of ECMAScript?

The problem is that opting out of mime type negotiation simply because there is a catch-all in there is wrong according to the specifications of HTTP.

Some variety of markdown support the following syntax, but not supported in Hugo/BlackFriday. [Lua Software](http://www.luasoftware.com){:target="_blank"}

Rails also adds a test method that takes a test name and a block. It generates a normal Minitest::Unit test with method names prefixed with test_. So you don't have to worry about naming the methods, and you can write something like:

enquo() uses some dark magic to look at the argument, see what the user typed, and return that value as a quosure
