  • K8s KPIs with Kuberhealthy

    Last November at KubeCon San Diego 2019, we announced the release of Kuberhealthy 2.0.0 - transforming Kuberhealthy into a Kubernetes operator for synthetic monitoring. This new ability granted developers the means to create their own Kuberhealthy check containers to synthetically monitor their applications and clusters. The community was quick to adopt this new feature and we’re grateful for everyone who implemented and tested Kuberhealthy 2.0.0 in their clusters. Thanks to all of you who reported issues and contributed to discussions on the #kuberhealthy Slack channel. We quickly set to work to address all your feedback with a newer version of Kuberhealthy. Additionally, we created a guide on how to easily install and use Kuberhealthy in order to capture some helpful synthetic KPIs.

  • Empowering remote teams to collaborate in a WFH world

    Many more people are working at home these days, and although much of this started with COVID-19, remote work from home (WFH) could become standard procedure for businesses around the world.

    Team members may no longer work on-site, in the same building, but proper communication and collaboration is still the foundation of teamwork. Of course, this means teams need to conduct remote meetings on a regular basis, more than they ever have before. Many of us already attend conference calls all the time, but remote meetings—where every team member is working from home—that is a completely new encounter for most teams.

  • Denuvo's Anti-Cheat Software Now Getting Ripped From Games At Record Speed Too

    Remember Denuvo? Back in the far simpler times of 2016-2018, which somehow seem light years better than 2020 despite being veritable dumpster fires in and of themselves, we wrote a series of posts about Denuvo's DRM and how it went from nigh-uncrackable to totally crackable upon games being released with it. Did we take a bit too much pleasure in this precipitous fall? Sure, though our general anti-DRM stance sort of mandated dunking on a company that once touted itself as invincible. Either way, it started to get comical watching publishers release a game with Denuvo, have the game cracked in a matter of days, if not hours, and then release a patch to remove Denuvo entirely from the game.

  • What happens when you run Linux on a toaster?

    In today’s data centre, software-defined-everything is the new normal, and for plenty of good reasons: agility, flexibility, longevity. Amongst all the hype however, the precious role of hardware in the ecosystem seems to have been forgotten, cast aside in the insatiable quest for better results. But what has that actually done for those hard-fought-for results? Are you cashing in on false efficiencies by using cheap, off-the-shelf, generic appliances? We’d like to argue that yes, you have.

    Hardware has been so commoditised in the data centre to the point of obscurity, and in so doing, we’ve shot ourselves in the foot because it’s been to the detriment of the results we’re seeking.

    Think about it - just because you can build a toaster that runs Linux, it doesn’t mean you should.

  • Speed up administration of Kubernetes clusters with k9s

    Usually, my articles about Kubernetes administration are full of kubectl commands for administration for your clusters. Recently, however, someone pointed me to the k9s project for a fast way to review and resolve day-to-day issues in Kubernetes. It's been a huge improvement to my workflow and I'll show you how to get started in this tutorial.

    Installation can be done on a Mac, in Windows, and Linux. Instructions for each operating system can be found here. Be sure to complete installation to be able to follow along.

    I will be using Linux and Minikube, which is a lightweight way to run Kubernetes on a personal computer. Install it following this tutorial or by using the documentation.

  • 50 Frequently Asked Hadoop Interview Questions and Answers

    Storing and processing big data has remained the biggest challenge until today since the beginning of its journey. It is important to be able to compute datasets to generate solutions for businesses. But sometimes, it becomes really challenging to produce accurate results due to the outliers, scarcity of sources, Volume, and inconsistency. But there is no value of big data if you can not use it or extract meaningful information. The below mentioned Hadoop Interview Questions would help you to get a solid foundation and face interviews as well.

  • PlanetScale scales out MySQL

    An open source technology first implemented at YouTube is now being rolled out to scale-out MySQL-compatible databases.


    The core technology, Vitess, is intended to enable SQL databases to scale out in a manner similar to NoSQL platforms like MongoDB, relying heavily on sharding. Acting as classic black box middleware, it logically shards the database on the presumption that most queries are going to be around data associated with specific records. So, it groups all data with common record IDs on the same shard. It also provides connection pooling to overcome the high memory overhead that is common with MySQL implementations so that the platform can handle high concurrency. And to further protect the database from getting overloaded, it has query limiters that throttle so-called "queries from hell."

    Vitess has been initially designed to support MySQL and related platforms like MariaDB, providing a middleware tier that allows you to implement the regular edition of the database, with the middleware handling all the scale-out. According to Vaidya, the technology could also theoretically support PostgreSQL as well, but as a start-up, they are focusing on their existing sweet spot.

    If this all sounds like a familiar story, it is. Vitess in many ways resembles a latter-day reinvention of the classic transaction processing (TP) monitors of the 1990s. At the time, distributed transaction databases were not feasible, and so the only alternative was to run transactions on a single node that would scale up. And given that most database platforms at the time were licensed based on processing power, TP monitors helped reduce server requirements by offloading transaction processing, and handling all the connection pooling. It was a highly contentious issue for database providers at the time – many would invalidate license if their caught their customers in the act. But when the Internet started delivering scales of transactions that overwhelmed even the most properly-licensed servers, TP monitors got reinvented as appservers, with many of those same database companies now biting the bullet.

Better than Zoom: Try these free software tools for staying in touch

Filed under

The COVID-19 pandemic has caused an enormous amount of changes in how people work, play, and communicate. By now, many of us have settled into the routine of using remote communication or video conferencing tools to keep in touch with our friends and family. In the last few weeks we've also seen a number of lists and guides aiming to get people set up with the "right" tools for communicating in hard times, but in almost every case, these articles recommend that people make a difficult compromise: trading their freedom in order to communicate with the people they care about and work with.

In times like these it becomes all the more important to remember that tools like Zoom, Slack, and Facebook Messenger are not benign public services, and while the sentiment they've expressed to the global community in responding to the crisis may be sincere, it hasn't addressed the fundamental ethical issues with any piece of proprietary software.

After taking the LibrePlanet 2020 conference online, we received a number of requests asking us to document our streaming setup. As the pandemic grew worse, this gave way to more curiosity about how the Free Software Foundation (FSF) uses free tools and free communication platforms to conduct our everyday business. And while the stereotype of hackers hunched over a white on black terminal session applies to us in some ways, many of the tools we use are available in any environment, even for people who do not have a lot of technical experience. We've started documenting ethical solutions on the LibrePlanet wiki, in addition to starting a remote communication mailing list to help each other advocate for their use.

In the suggestions that follow, a few of the tools we will recommend depend upon some "self-reliance," that is, steering clear of proprietary network services by hosting free software solutions yourself, or asking a technical friend to do it for you. It's a difficult step, and the benefits may not be immediately obvious, but it's a key part of preserving your autonomy in an age of ubiquitous digital control.

  • Bitcoin SV Node team introduces new version 1.0.3

    One of the changes included is the ability for the single release binary to run on both Ubuntu 18.04 and CentOS 8. For Linux fans that prefer either Ubuntu 16.04 or CentOS 7, the binary would have to be built manually, but Bitcoin SV Node developers have included the instructions on how to carry out the procedure with the new 1.0.3 release. It would most likely be easier to update the OS software, though, and use the single release binary.

  • [buzzword drives buzzword] How Serverless Accelerates DevSecOps

    Serverless drives agility and speed, but that’s not all that a well-architected serverless approach enables. Serverless is a catalyst for improving security too.

    With DevOps processes, the concept of Infrastructure-as-Code is a recommended best practice. In a serverless approach, treating infrastructure-as-code isn’t only recommended, it’s required. There is no way around it. The great benefit of embedded infrastructure-as-code approaches is that from the onset of the software development lifecycle, security can be integrated into the process.

    With serverless, DevSecOps is a reality where engineers can architect with tightly scoped roles, and develop with fine-grained permissions as part of the process, without losing speed.

8 Best Free and Open Source Linux Renderers

One of the many strengths of Linux is its good range of open source software for artists, photographers, animators, and designers. With inexpensive hardware, free software, and a modicum of talent and inspiration, anyone can create professional-looking computer graphics. If you are new to computer graphics, it may not be clear what is meant by the term rendering. To clarify, rendering is the process of generating an image from a model (or a collection of models, known as a scene file) using computer software. This entails the computer software to perform calculations to translate the scene from a mathematical approximation to a 2D image. To generate the image, the scene file contains objects in a defined language or data structure, containing geometry, lighting, shading, texture, and viewpoint. This data is processed by the rendering software to generate a raster image file or a digital image. Read more
