Go file walk implementations have radically different performance characteristics. In 2021 the native implementation has improved so much, you don't need anything else.

Memcached and Redis. More different than first appearances would suggest. From how they use memory to how they expire items, the differences are not as subtle as you would expect.

I have learnt much from experiencing the workflows and practices at Kablamo. Let me tell you about my insights after seeing firsthand how great an impact it can have on productivity.

Recurring revenue is considered the holy grail for any technology business with SaaS being the main way to achieve this. In 2021 while more people are using the internet than ever, building your SaaS it's harder than ever.

GeoJSON is an open format for geographical data and is used in a wide range of software products and libraries. Golang is a strictly typed language, which means that expressing the data model of GeoJSON can be challenging, because the data structure will change depending on what geometry type you want to represent.

It might seem obvious but loading everything into memory is a bad idea. GoDoc examples, tutorials and Stack Overflow posts often use byte slices because its a quick way to illustrate a point but it is rarely the ideal data structure for engineered software solutions.

Are you still having an uphill battle with security, does it always feel like just one more problem to solve? Or you treat it more like a feature that gets de-prioritised at each of your Sprints? Perhaps you sometimes even struggle to understand what that "security hype" is all about? Read on and discover how to embrace security to make it the cornerstone of any information system you build.

This approach can be used to easily mock out any part of the code, including HTTP calls, database queries, and more. There is also an added advantage of making the code more modular and maintainable. Try this out on your own codebase and see how much more of your code you can test!
