Loops in Rust aren’t the same as standard C-style languages. The syntax is different and there are some powerful options that make looping easier. First, let’s go over some looping basics, then we will cover how to handle breaking and continuing in nested loops in Rust. Standard For-Loop Which prints: 0..10 is an iterator where … Read more
Let’s take a look at some of the common pitfalls with the keywords let and mut. Then, we will learn how immutable != constant by using variable shadowing. Getting started with Rust can be daunting. Rust is well-known for being a safe language. One of the ways in which Rust is safe is through type-safety. … Read more
One of the primary goals of the Go programming language is to make concurrency simpler, faster, and more efficient. With Rust growing in popularity let’s see how its concurrency mechanisms stack up against Go’s. A Refresher On Goroutines In Go, concurrency is accomplished by spawning new goroutines: In the example above, we use the go … Read more
Go and Rust are two of the hottest compiled programming languages, but which is more popular, Go or Rust?. I develop in Go full-time and love it, and I’m learning more about Rust recently – it’s an exciting language. Let’s explore some differences between the two and look at which is growing faster in the … Read more
Data integrity refers to the accuracy, legitimacy, and consistency of information in a system. When a message is sent, particularly using an untrusted medium, data integrity provides us confidence that the message wasn’t tampered with. For example, the SSL signature of Qvault provides confidence that the webpage and data coming from our servers are really … Read more
The Go standard library has a really cool type – Ticker. Tickers are used when you want to do something at a regular interval, similar to JavaScript’s setInterval. Here’s an example: As per the docs, a ticker is a struct that holds a receive-only channel of time.Time objects. In the example at the beginning of … Read more
RabbitMQ is a great message broker with awesome Golang support. It’s a great pub-sub system, and pub-sub has become a staple communication architecture in micro-services. At my current day job, we use RabbitMQ to push hundreds of millions of social media posts through our Go services daily. Let’s take a look at how to efficiently … Read more
White-box cryptography combines methods of encryption and obfuscation to embed secret keys within application code. The goal is to combine code and keys in such a way that the two are indistinguishable to an attacker, and the new “white-box” program can be safely run in an insecure environment. What Does “White-Box” Mean? In penetration testing, … Read more
In microservice architectures, it is fairly common to have a project that includes different worker types. A Makefile can be used to manage the creation of multiple programs, but the Go toolchain has a great tool that can be used as well, go generate. Here are some examples of how we take advantage of ‘go … Read more
An anonymous struct is just like a normal struct, but it’s defined without a name, and as such can’t be referenced elsewhere in code. Structs in Go are similar to structs in other languages like C. They are typed collections of fields, and are used to group data together in order to make it more … Read more
