    The business networking platform LinkedIn uses MySQL extensively as a back-end data store for both internal and public-facing assets.

    LinkedIn has a centralized MySQL site reliability engineering (SRE) team that provides MySQL as a managed service inside of the company, which uses about 2,300 MySQL databases currently.

    LinkedIn engineer Karthik Appigatla, during a technology keynote session Wednesday at the 24-hour Percona Live Online conference, outlined how the business networking site has managed to scale and secure its MySQL deployment.

    Meanwhile, e-commerce platform vendor Shopify has seen firsthand some of the problems when deploying database services in the cloud. The Ottawa-based vendor deploys its fleet of MySQL services on the Google Cloud Platform at large scale.

    Shopify engineers Akshay Suryawanshi and Jeremy Cole, outlined some of the challenges they faced with cloud deployment during a technology keynote session at the Percona conference on May 19.

    Suryawanshi noted that Shopify is used by more than a million merchants during the peak Black Friday through Cyber Monday shopping period (Nov. 29 to Dec. 2 in 2019) and it can handle hundreds of millions of queries across its MySQL infrastructure.

    A key promise of the cloud is the concept of elastic scalability that enables users to start up new servers on demand to handle traffic. Cole noted that sometimes the instant, on-demand promise doesn't actually always work out as expected.

My Linux story: From Linux user to contributor

I am an IT professional with over 15 years of experience in a number of different roles—systems administrator, senior Linux administrator, DevOps engineer, automation consultant, and senior scrum master. I started learning Linux on Ubuntu but shifted to CentOS as a sysadmin, and later I moved to Fedora for personal use. But my joy for technology started much earlier than my first Linux distribution, and it came in the form of a movie. My favorite movie is Hackers. The best scene occurs at the beginning of the movie. The movie starts with a group of special agents breaking into a house to catch the infamous hacker, Zero Cool. We soon discover that Zero Cool is actually 11-year-old Dade Murphy, who managed to crash 1,507 computer systems in one day. He is charged for his crimes, and his family is heavily fined. Additionally, he is banned from using computers or touch-tone telephones until he is 18. Read more

  • The [Perl] Weekly Challenge #068

    The Week #068 is my 23rd week in a row participating the weekly challenge. For the first time, I created a package to deal with the “Reorder List” task. It really helped me in thinking straight when dealing with linked list. With the help my favourite CPAN module Moo, creating class is like piece of cake as shown below.

  • Hey, Back Off!

    The choice in parameters for back-off configuration is important. It can be the difference between a barely noticable blip in service quality and an hours-long site outage. In order to explore the consequences of the choice, I wrote a little fictional ditty about a fictional website. I hope you enjoy escaping into this fictional reality as much as I enjoyed writing about it. Your recipe site is different. After all, recipe sites are a dime-a-dozen. With today's modern technology, any kid can put a quick mock-up together with Django, React, and MongoDB to store recipes and retrieve them by various attributes. In order to make your recipe site stand above the rest, you made sure it uses really cutting edge techniques. From details of the web requests coming in, using sophisiticated language parsing and machine learning algorithm, with just a few words about the user's likes and dislikes, you find the perfect recipe just for them. HackerNews called it "just a bunch of buzzwords", of course. But once the graphs went up into the right, with 50% month-over-month growth rates, everyone explained that they knew that this one was different. Popularity sky-rocketed, the engineers worked on scaling up the site, and though it was not the world's most sophisticated microservice architecture, it was medium-service architecture, at least. The web front end would call the machine learning cluster, running on special GPU machines, to get the appropriate keywords by which to look up the recipe. Maybe not a the kind of 50-microservices-architecture that takes three whiteboards to explain, but at least it was easy enough to scale up horizontally. You hired a great Site Reliability Engineer, who built a sophisticated continuous delivery machine. As your machine learning team fine-tuned the model, it would slowly roll out into the cluster, running continous A/B tests that would immediately roll back the change if the model performed worse than before.

Games: Celeste/Stadia, How to Play Windows Games on GNU/Linux, MOBAs on Android

  • What have you been playing lately? It's chat time

    Wow, the end of another week over here in the surprisingly hot and sunny UK. Perfect weather to be sat inside playing games and there's been plenty of that here. Thanks to the news of Celeste coming to Stadia, I was reminded of the fact that Celeste was in the recent itch.io charity bundle so I've been able to give it a thorough go after only previously playing it at a friends PC. I already liked it a lot but now I've sunk plenty more hours into it I'm totally blown away by it. It's truly no surprise to me now why it has amassed such a following, like on Steam where it has over twenty thousand views an an overall Overwhelmingly Positive rating.

  • [Older] How to Play PC Games on Linux

    If you’re new to Linux, check out our switcher’s guide before reading this, as it helps to know the basics. There’s no one distro that’s “best” for gaming, but Ubuntu-based distros like Ubuntu, Linux Mint, and Pop!_OS are good options for their widespread support and helpful communities. If you have a different Linux environment on your system, you may have to research the best way to install the right packages and drivers. However, you can almost certainly get games working. Before trying anything, you should make sure your distro comes with the requisite graphics drivers. If not, Nvidia users should grab the company’s official proprietary drivers, and AMD users should install the open-source Mesa drivers. The procedure for installing drivers may vary from system to system, so we won’t get into it too deeply here, but I used these instructions for Linux Mint for the drivers and these instructions for some extra Vulkan packages, which produced good results. Now, before we continue, temper your expectations just a tad. While Linux gaming is easier than ever, it still isn’t on par with Windows. Some games won’t run at all, and others may have small graphical quirks, or decreased performance. Others may require some Googling and command-line tweaking to get playable. The experience isn’t exactly smooth as butter yet-it’s still very Linux-y-but once you have the basics down, you might be surprised at how many games you’re able to run. Here are your options.
