Sing, beastie, sing!
FreeBSD digital audio workstation, or DAW for short, is now possible. At this very moment it's not user friendly that much, but you'll manage. What I want to say is that I worked on porting some of the audio apps to FreeBSD, met some other people interested in porting audio stuff and became heavily involved with DrumGizmo - drum sampling engine. Let me start with the basic setup.

You Might Not Need GraphQL — Runscope Blog
Do you like the look of GraphQL, but have an existing REST/RPC API that you don't want to ditch? GraphQL definitely has some cool features and benefits. Those are all bundled in one package, with a nice marketing site, documenting how to do all the cool stuff, which makes GraphQL seem more attractive to many. Obviously seeing as GraphQL was built by Facebook, makers of the RESTish Graph API, they're familiar with various endpoint-based API concepts. Many of those existing concepts were used as inspiration for GraphQL functionality. Other concepts were carbon copied straight into GraphQL. Facebook has experimented with various different approaches to sharing all their data between apps; remember FQL? Executing SQL-like syntax over a GET endpoint was a bit odd. Facebook got a bit fed up with having a one-endpoint-based approach to get data and this other totally different thing, as they both require different code. As such, GraphQL was created as a middle-ground between endpoint-based APIs and FQL, the latter being an approach most teams would never consider - or want. That said, Facebook (and others like GitHub) switching from RESTish to GraphQL makes folks consider GraphQL as a replacement for REST. It is not. It is an alternative. Whilst the use-cases for the sort of API you'd build in GraphQL are quite different from those you'd build with REST (more on this) or RPC, that...

Enlightened - What the Daily WTF?
Calling an invalid function on an object can result in:

- Nothing, leaving you wondering WTF.

- An extremely helpful console message: “SPANK! SPANK! SPANK! Naughty programmer!”. Really, I’m not joking about that one.

- Another extremely helpful message: “You bitch!”. And I’m not joking about that one either – it was discovered by a female coworker while trying to hack layouts to work. Perfect timing on EFL side here.

- A crash, if you’re lucky, so you can debug the issue.
