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.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
$ python -m SimpleHTTPServer 8000

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.
The following are examples of the four types rate limiters discussed in the accompanying blog post. In the examples below I've used pseudocode-like Ruby, so if you're unfamiliar with Ruby you should be able to easily translate this approach to other languages. Complete examples in Ruby are also provided later in this gist.
In most cases you'll want all these examples to be classes, but I've used simple functions here to keep the code samples brief.
This uses a basic token bucket algorithm and relies on the fact that Redis scripts execute atomically. No other operations can run between fetching the count and writing the new count.
Here are the simple steps needed to create a deployment from your local GIT repository to a server based on this in-depth tutorial.
You are developing in a working-copy on your local machine, lets say on the master branch. Most of the time, people would push code to a remote server like github.com or gitlab.com and pull or export it to a production server. Or you use a service like deepl.io to act upon a Web-Hook that's triggered that service.

| ---------------- | |
| A consistent frame-rate can be better than a janky experience only | |
