Go: inlining strategy & limitation BY VINCENT BLANCHON

Go: discovery of the trace package BY VINCENT BLANCHON
5 minutes - Go provides us a tool to enable tracing during the runtime and get a detailed view of the execution of our program. This tool can be enabled by flag -trace with the tests.
A Go module testbed BY CHRIS WELLONS
5 minutes - I learned that Go 1.14 has as a new feature: GOINSECURE. It’s like the old -insecure option, but safer due to being finer grained: a whitelist of exceptions. It’s exactly what I needed. Since then I’ve been using it to run small module experiments. It started as some scripts, but I eventually formalized it into its own little project.
Hidden options for testing BY GEORGE K. MACRORIE
4 minutes - Before I get into the crux of this post, you should become familiar with a couple useful concepts in Go: functional options, using an external test package and mocking time.Now in tests.
Migrating to CockroachDB BY KARL SEGUIN
4 minutes - I recently had the opportunity to put a system into production backed by CockroachDB. While I’m a huge fan of PostgreSQL, I wanted something that provided better out of the box support for high availability.
SSH environment variables in Go BY VIC DEMUZERE

'Remember me' w/ the Gorilla framework BY JIMMY JOHN
4 minutes - A ‘Remember Me’ type functionality is something that is available on most websites today. Essentially what it does is that if the checkbox is checked when logging in, the session is kept logged in for a much longer duration (say a week or month).

Unusual uses for Go BY ANDREW WILLIAMS
67 minutes - A long podcast discussing graphical toolkits in Go.
A crystal in Go’s world BY PRESLAV RACHEV
3 minutes - Imagine a programming language with the ergonomic syntax of Ruby, the speed of execution of C, the concurrency model of Go, and last but not least, a compiler that performs null checks at compile time. Sounds like a dream? Well, this language exists, but chances are, you haven’t heard of it so far. Meet Crystal!
Go must() underrated? BY RYAN WESTLUND
2 minutes - The inconvenience of error-handling has been one of my biggest complains about Go for a long time, but at my job, we have a function must.
Analyzing attacks on my server BY JEREMY MORGAN
5 minutes - I was casually doing a security audit on my blog recently and looked a little deeper into my security logs. With a bit of Linux command line kung fu, some Go, and Google sheets, I could get a pretty good idea of where the attacks are coming from.
Losing the source code for installed programs BY CHRIS SIEBENMANN
3 minutes - When I compared Go to Python for small scale sysadmin tools, I said that one useful property for Python was that you couldn’t misplace the source code for your deployed programs.
Academic articles Safe systems in Rust: promise and challenge BY RALF JUNG, JACQUES-HENRI JOURDAN, ROBBERT KREBBERS & DEREK DREYER
15 minutes - Rust is the first industry-supported programming language to overcome the longstanding tradeoff between the safety guarantees of higher-level languages (like Java) and the control over resource management provided by lower-level "systems programming" languages (like C and C++).
Implicit functions --> abstraction opportunities BY JONATHAN BRACHTHÄUSER & DAAN LEIJEN
15 minutes - We introduce two new language features, called implicit functions and implicit control. Both generalize implicit values which are a typed implementation of dynamic binding. Implicit functions are a small extension that creates new opportunities for abstraction while avoiding the need for full continuations in the implementation. We hope to see more languages that will support this feature.
