If you're using a high-end bluetooth headset on your Macbook Pro it's likely your mac is using an audio codec which favors battery efficiency over high quality. This results in a drastic degradation of sound, the SBC codec is the likely culprit, read more about it here.

| iOS Create a Carthage Supported Framework | |
| #iOSBySheldon | |
| A little bit Background of Carthage: | |
| - Carthage works like Cocoapods, but a little bit simpler. | |
| * When creating a Cocoapods supported framework need a .podspec file to do some config, which is not required by Carthage. | |
| * When using a Cocoapods supported framework, a workspace file will be automatically created, the umbrella header will be setup in a pod project inside workspace. It feels simple, but the whole process creates a lot files including a "giant" workspace. | |
| * When using a Carthage supported framework, it will just download the framework, and its dependencies if any, to a folder. All we need to do is to drag and drop it to the binary linking section in the project build setting tab, for the first time. It sounds complicated but it makes the project clean. | |
| - Carthage is written in Swift. | |
| - Carthage internally uses `-xcodebuild` to build dependency. |
Cian Johnston, July 2017
A couple of weeks ago, I decided I should put my gaming rig to work crypto mining. I did not expect to make any significant profit on this, it was more of a fun project to set up. However, there were a large number of tutorials and guides already out there, and many were more than a year out of date.
This guide assumes the reader already has a crypto wallet set up, is comfortable with Linux and the command line, and knows how to use Google if they run into problems.
The end result is an Ubuntu 16.04 LTS headless server running CUDA ethminer via systemd.
