Useful Resources for Those Who Want to Know More About Linux

Linux is one of the most popular and versatile operating systems available. It can be used on a smartphone, computer and even a car. Linux has been around since the 1990s and is still one of the most widespread operating systems.

Linux is actually used to run most of the Internet as it is considered to be rather stable compared to other operating systems. This is one of the reasons why people choose Linux over Windows. Besides, Linux provides its users with privacy and doesn’t collect their data at all, while Windows 10 and its Cortana voice control system always require updating your personal information.

Linux has many advantages. However, people do not hear much about it, as it has been squeezed out from the market by Windows and Mac. And many people get confused when they start using Linux, as it’s a bit different from popular operating systems.

So to help you out we’ve collected 5 useful resources for those who want to know more about Linux.

Today I’m glad to publish a guest post about Galera a software that I’ve used in the past to manage a multi-master mysql cluster:

MariaDB Galera Cluster is a multi-master cluster for MariaDB. MariaDB Galera Cluster currently supports only the InnoDB/XtraDB storage engine. It is mostly used for database redundancy as it consists of multiple master servers that are synchronized and connected to each other. In today’s tutorial we are going to learn how to install MariaDB Galera Cluster on a clean Ubuntu 16.04 VPS, on optimized MariaDB hosting.

Docker and the ecosystem around it have done some great things for developers, but from an operational standpoint, it’s mostly just the same old issues with a fresh coat of paint. Real change happens when we change our perspective from Infrastructure (as a Service) to Platform (as a Service), and when the ultimate deployment artifact is a running application instead of a virtual machine.

Even Kubernates still feels a lot like IaaS – just with containers instead of virtual machines. To be fair, there are already some platforms out there that shift the user experience towards the application (Cloud Foundry and Heroku come to mind), but many of them have a large operations burden, or are provided in a SaaS model only.

In the Docker ecosystem we are starting to see more of these types of platforms, the first of which was Dokku which started as a single machine Heroku replacement written in about 100 lines of Bash. Building on top of that work other, richer systems like Deisand Flynn have emerged, as well as custom solutions built in-house, like Yelp’s PaaSta.

Storing large binary files in git repositories

This is a small update (1 year later) of a great article by Ilmari Kontulainen, first posted on blog.deveo.com.

I’ll post the original article in blockquote and my notes in green.

Storing large binary files in Git repositories seems to be a bottleneck for many Git users. Because of the decentralized nature of Git, which means every developer has the full change history on his or her computer, changes in large binary files cause Git repositories to grow by the size of the file in question every time the file is changed and the change is committed. The growth directly affects the amount of data end users need to retrieve when they need to clone the repository. Storing a snapshot of a virtual machine image, changing its state and storing the new state to a Git repository would grow the repository size approximately with the size of the respective snapshots. If this is day-to-day operation in your team, it might be that you are already feeling the pain from overly swollen Git repositories.

Luckily there are multiple 3rd party implementations that will try to solve the problem, many of them using similar paradigm as a solution. In this blog post I will go through seven alternative approaches for handling large binary files in Git repositories with respective their pros and cons. I will conclude the post with some personal thoughts on choosing appropriate solution.
