Installing Oh My ZSH oh Fedora (2015 CIT 325 Image)

Installing oh-my-zsh on Fedora (for DB class images)

Oh-my-zsh is an extension of the traditional z shell that is extensible via community created plugins (Plugins found here: oh-my-zsh github repo). It is, in my opinion, a breath of fresh air in comparison to the traditional bash shell.


Installing ZSH (using yum)

The first step for this install is getting zsh we will do this via yum. From your terminal:

public io.opentracing.Tracer jaegerTracer() {
Builder builder = new Builder("spring-boot",
new RemoteReporter(new HttpSender("http://jaeger-collector.istio-system:14268/api/traces"), 10,
65000, new Metrics(new StatsFactoryImpl(new NullStatsReporter()))),
new ConstSampler(true))
.registerInjector(Builtin.HTTP_HEADERS, new B3TextMapCodec())
.registerExtractor(Builtin.HTTP_HEADERS, new B3TextMapCodec());

Time Series Analysis
pytsa (read "pizza") depends on scipy and numpy.
Pytsa is a simple timeseries utility for python.
It is good for pedagogical purposes, such as to understand moving averages,
linear regression, interpolation, and single/double/triple exponential smoothing.
You can’t perform that action at this time.
