Linux is a vast ecosystem of operating systems. Unlike Windows or macOs variants, there are loads of Linux distributions (distros) available. But these distros often differ greatly. Whether you're just getting started with Linux, or are a seasoned pro, here are the tips and tricks you need to know. Picking the Right Linux Operating System Whereas Windows and macOS offer fairly few choices for their operating system (OS) options, Linux presents a ton of flavors.

A process to build RESTful APIs that solve users’ needs with simplicity, reliability, and performance. Every piece of software exists to solve a real-world problem. Directly or indirectly. Most web APIs are consumed by client applications running on PCs, mobile devices, etc., which in turn are used by humans. Despite being consumed directly by machines, APIs are made to satisfy the needs of human beings, so designing them should follow a user-centered process, but often it doesn’t.

I've written a lot of posts about page bloat, starting way back in 2012, when the average page hit 1MB. To my mind, the topic had been well covered. We know that the general trend is that pages are getting bigger at a fairly consistent rate of growth.

So I was researching object storage and I came across the open source distributed object storage software, Minio. This lightweight software was written with Golang and accomplishes similar things to that of Amazon S3. After all they are both object storage solutions. The difference here is that Minio can be deployed on your own hardware. Being that Minio was written with Golang, it is cross platform for different computing architectures, ARM included.

Decision making is tricky business. Decisions often move up and down the chain of command without the input of those best equipped to make those decisions. In smaller companies, there's often too much reliance on the CEO, and that doesn't scale as the company grows.
