Let’s Make an NTP Client in Go
https://t.co/ZTEwLXXnLX

While doing some research on network programming, I came across this blog post titled Let’s Make a NTP Client in C by David Lettier (Lettier). So, that got me inspired to do something similar in Go.

Measuring progress and estimating time remaining of io.Copy and other long running io.Reader/io.Writer
https://t.co/KuGKgb0xVk

Whenever we use helpers like io.Copy and ioutil.ReadAll like when we are reading from an http.Response body or uploading a file, we find that these methods block until the process is complete, even if it takes minutes or hours — and we have no way of tracking its progress or figuring out an estimate of how much time is remaining until completion.

Various Ways of Reading Files in Go
https://t.co/XIXmCYblNd

When I started learning Go, it was hard for me to get a handle on the various APIs and techniques that can be used to read files. My attempting at writing a multi-core wordcounter (kgrz/kwc) shows evidence of this initial confusion—multiple ways used in the same file.

Go makefile #golang

While browsing some github repositories I stumbled over one that used a makefile as the projects task tool. I really like this solution for the following reasons:

Go Makefile • Oppodelldogs tech blog

While browsing some github repositories I stumbled over one that used a makefile as the projects task tool. I really like this solution for the following reasons:
Unified entry point for human and build server
Where yopu every trapped in the situation to find tests are executed differently on build server than on your local machine? So a makefile (and of course every task-tool) gives you the ability to define a central entry point for you, the developer and your build-server.

Be Careful with Table Driven Tests and t.Parallel()
https://t.co/J2ReZJX6pe

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

The Go programming language has no built in abs function for computing the absolute value of an integer. That is, the non-negative representation of a negative or positive number.
