  • Hudi powering data lake efforts at Walmart and Disney+ Hotstar

    The open source Apache Hudi data lake project is helping power large deployments at a number of big enterprises, including Uber, Walmart and Disney+ Hotstar.

    Apache Hudi (Hadoop Upserts, Deletes and Incrementals) is a technology that was originally developed at Uber in 2016 and became an open source project the following year.

    In June 2021, Hudi became a Top-Level Project at the Apache Software Foundation, which was a major milestone for the project's maturity. Hudi provides a series of capabilities for data lakes, including a table format and services that enable organizations to effectively manage data for data queries, operations and analytics.

  • Aditi’s Open Source Journey

    Hi! I am Aditi from India.

    According to Wikipedia, India annually produces 1M engineering graduates! (Yep! That’s a lot). And I am one of the 1M graduating in 2022. Just like most people, when I started studying back in 2018, I was pretty lost!

    I spent my first three semesters trying to find a perfect road-map to being a good developer in a sea of infinite possibilities, skimming through various options. I wasn’t sure what I was going to do, I just knew, I liked being in the field! It took me 1.5 years to realize that there is no perfect roadmap, it’s just as simple as when you start something, you like it, you stay consistent and end up in the right place!

    [...]

    One of the best pieces of advice I received from her: “Switch from Windows to Linux!”

    [...]

    I finished my outreachy initial application and devoted all my time in finding the perfect organization. That’s when I found GNOME. The skills required were C++ and JS – two languages I knew I had some experience in and liked working with. The GNOME community was indeed awesome. I never felt like an outsider. And that’s when I met Philip Chimento, one of the best mentors I’ve ever had. I remember being super excited when I finished building my first small app using GJS! (It just read a file and returned the number of lines, but it worked and that felt like a good enough reason to go on! Big Grin). I couldn’t wait to officially start my internship with GNOME but my Outreachy initial application got rejected again because of time commitment issues.

  • Fileless Malware on Linux: Anatomy of an Attack | LinuxSecurity.com

    Recent years have demonstrated that Windows users are not the only ones who should be concerned about malware. Linux is becoming an increasingly popular target among malware operators due to the growing popularity of the open-source OS and the high-value devices it powers worldwide. Security researchers from AT&T Alien Labs are now warning that “cyber gangs have started infecting Linux machines via a fileless malware installation technique that until recently was more commonly used against Windows-based systems”.

    So what exactly is fileless malware and how does a fileless malware attack on Linux work? This article will provide you with answers to these questions by honing in on the anatomy of a Linux fileless malware attack - equipping you with the knowledge necessary to secure your systems and your data against this stealthy and malicious threat.

Hackers getting married

We had several of our old-time friends from the GNU Project, and some guests with young children still unused to such an international context who soon enough learned to enjoy the sound of different languages and the happy chaos of people meeting for the first time, some more traditional if not formal, others fun and weird.

  • OS consistency solves Linux talent issues, says RHEL executive

    The new Red Hat Enterprise Linux, released during the recent Red Hat Summit, caters to rapidly escalating hardware development occurring throughout tech, along with a growing Linux admin skills shortage. RHEL 9 performs the combo double act, in part, by more efficiently optimizing the operating system, according to Gunnar Hellekson (pictured), general manager of the Enterprise Linux Business Unit at Red Hat Inc. Upgrading to the new OS means enterprises can get by with fewer admins. A skills shortage is caused, in part, by a lack of U.S. visas.

These two Linux desktops are the simplest picks for new users

Let's face it, any time you come across articles that offer advice on choosing the right Linux distribution, they tend to get bogged down in a lot of technical advice that rarely (if ever) applies to those who've never experienced Linux. They'll speak of things like rolling releases, package managers, kernels, open-source licensing, and other features and ideologies that not only have little bearing on those new to Linux and open-source technology but mire the decision in unnecessary complications. I want to take a very different approach, one that should make the process quite simple for anyone looking to dive into the world of desktop Linux for the first time. I'm going to shrug off the usual advice and aim straight for the heart of the matter. What exactly is that matter? Read more
