[settings] OBS settings for streaming with not so great internet

OBS Low Internet Settings

These were provided to me by @feross at some point and then I tweaked them to work with slow internet, i.e. 1MBPS up.

I'm posting the the screenshots of those settings in the comments and I added two files that I found via File/Show Profile Folder

Understanding why the new V8 is so Damn Fast, One Demo at a Time


The entire V8 compiler architecture as well as large parts of the Garbage Collector where updated recently. TurboFan replaced Crankshaft, Orinoco now collects garbage in parallel whenever possible. Node.js v8 shipped with this new and improved version of V8. As a result we can finally write idiomatic and declarative JavaScript without worrying about incurring performance overhead due to JavaScript compiler shortcomings.

At least this is what the V8 team tells us. In this talk we will explore if and why this is true, one demo at a time.

async/wrap express wrapper


Tried to improve debugging when an express middleware is wrapped to auto-handle errors of an asnync function.

Turns out the below reads a bit better than a return Promise.catch() implementation, but still, once we reach the central express error handler, the line of the wrapped function that caused the error isn't included.
