Hash functions are used to securely store passwords, find duplicate records, quickly store and retrieve data, among other useful computational tasks. As a practical example, all user passwords on boot.
The podcast is available here. Before I begin, I must give thanks to Nick for having me on the show! In this episode of Running in Production, I talk with Nick about how we built boot.dev, an open-source password manager that specializes in cryptocurrency. Boot.
Many new developers are jumping right into writing code, usually for those fat paychecks, without learning much about the history of Computer Science. Alan Turing is recognized as the father of Computer Science, though many don’t know that his roots were in cryptology and mathematics.
There are many ways to traverse an array in Javascript. In this benchmark, we will look at five different ways and the pros and cons of each. Keep in mind that these benchmarks were run in a Chrome browser on Codepen.io. Results will vary by browser/interpreter.
Once upon a time, a company I worked for had a problem, we had thousands of messages flowing through our data pipeline every second, and we wanted to be able to send real-time emails, SMS, and Slack alerts when messages matching specific criteria were found.
Singletons are fairly controversial as far as I can tell, especially in JavaScript programming. Let’s take a look at what they are, when to (maybe) use them, and when not to.
