Debian vs. Fedora

Filed under
Red Hat

Debian Linux and the Fedora Project are among the most influential Linux distributions of all time. Not only are both Debian and Fedora among the top ten for page hits on Distrowatch, but many of the other top ten are derived from them. But why would you pick one over another?

To be honest, the differences are fewer than they were fifteen years ago. In 2003, when Fedora began, Debian was the main representative of the .deb package format, and Red Hat, Fedora's predecessor, represented the .rpm format, and your Linux experience was very different depending on which you chose. Since then, the differences have diminished, but there are still subtle differences that might influence your choice.

However, those differences no longer include package management. Around the turn of the millennium,.debs were alone in resolving package dependencies, but .rpms added the feature long ago. Today, contrary to old myths that refuse to die, using Fedora's dnf command to install packages is roughly equivalent to installing packages with Debian's apt- get. Even the comparative slowness of yum, dnf's predecessor, has become irrelevant as the change of tools becomes complete.

Where differences do exist is in the organization, governance, available system architectures, package repositories, and default installations. These differences may affect your choice, or simply be necessary to know to avoid uncertainty.

  • Leveraging Open Source Reference Architectures Allows You To Give And Take From Broader Expertise

    Congratulations! As your company transitions to software-defined data centers, you’ve been put in charge of storage. Dream assignment, but so many choices. The good news is that by using open source storage software on industry standard hardware, you break the uncomfortable constraints of vendor lock-in. The bad news is there are so many choices of configurations to choose from. Where to start?


    Red Hat is the curator of reference architectures in the world of OpenStack and cloud-based storage, maintaining libraries of in-depth reference architectures, all free for the taking. Search Red Hat’s publications and data assets here.

  • Paul Smith: Red Hat’s Operating System Cryptographic Modules Get NIST Data Security Certifications

    The Red Hat Enterprise Linux 7.1 OS received nine FIPS certifications for modules that include OpenSSL, OpenSSH Server, OpenSSH Client, Libgcrypt, NSS, Libreswan, Kernel Cryptographic API, Kernel Cryptographic API with CPAFC and GnuTLS, Red Hat said Monday.

  • Pythonic code review

    Most of us programmers go through technical interviews every once in a while. At other times, many of us sit on the opposite side of the table running these interviews. Stakes are high, emotions run strong, intellectual pressure builds up. I have found that an unfortunate code review may turn into something similar to a harsh job interview.

    While it is theoretically in the best interest of the whole team to end up with high quality code, variations in individual's technical background, cultural differences, preconceptions built up on previous experience, personality quirks, and even temper may lure people into a fierce fight over relatively unimportant matters.

    Consider an imaginary pull request. There we typically have two actors: the author and code reviewers. Sometimes authors tend to overestimate the quality of their code which provokes them to be overly defensive and possibly even hostile to any argument. People reviewing the code may find themselves being in a position of power to judge author's work. Once the actors collide over a matter where they take orthogonal and sufficiently strong sides, all is fair in love and war.

Review: Fedora 25 - The Trail Blazer that is Blazing Fast

Filed under
Red Hat

Not long after being released to the wild, I decided it was time to retire old faithful Ubuntu GNOME in favour of Fedora 25 on my main laptop (an Optimus equipped machine). The Ubuntu install had served me very well indeed, but with Fedora's latest offering featuring the latest stable version of GNOME and Wayland now being used by default, it was a rabbit hole I decided to delve into...

In reality, the whole process is not quite so dramatic. When replacing one Linux distro for another, as long as you do all the usual sane backups and the distro you are replacing your old one with does all things you need it to, it's not such a big deal. After all, it's essentially one Linux for another Linux and most of your usual apps and tools will be available in one way or another.

Still, replacing a perfectly stable install of Ubuntu GNOME that had served me well for a good two years (even surviving a few Ubuntu version upgrades in the process) for both work and play probably seems a bit risky for a fresh new version of Fedora. And let's be honest, when it comes to new releases of Fedora, you never know quite what you are going to get. But in a way, that is part of the fun of it. Perhaps, I also had an itch for adventure.

So, how did Fedora 25 fare and how is it still faring, in my everyday use? Read on...

  • More Fedora 26 Change Proposals: Ruby, Golang 1.8, Go PIE, ZF3

    While the changes need to be cleared by the Fedora Engineering and Steering Committee (FESCo), the latest proposals look like they're relatively safe to assume they'll be accepted for this next major Fedora Linux release due out in 2017. The latest feature talk includes:

    - Golang 1.8. The Go Language v1.8 release is due out in February so should be safe to land for Fedora 26 in providing the latest Go support.

  • Fedora Docker Layered Image Build Service Now Available

    It is with great pleasure that the Fedora Project Announces the availability of the Fedora Docker Layered Image Build Service to the Fedora Contributor Community!

    With this announcement we open the availability of the Docker Layered Image Build Service for the Docker Layered Images. The Fedora Cloud WG has been the primary maintainers of this project on GitHub. But now the service is available in dist-git as official components of Fedora. From there we will extend an invitation to all Fedora Contributors to maintain Docker Layered Image Containers for official release by the Fedora Project. Currently this effort is to enable the Fedora Cloud/Atomic Working Group goals of targeting Fedora Atomic Host as a primary deliverable to power the future of Cloud. This is also to enable the Fedora Modularity work be delivered as Containers in the future as Fedora becomes fundamentally more modular in nature.

  • F25 Release Event Samos - Event Report

    I started with an introduction to the distribution and to the project as a whole. I explained the plethora of options being offered to our end users (Fedora Spins, Fedora Labs, Alternate Architectures). I passed the torch to Zacharias, who briefly spoke about before giving an in-depth look at the latest features. We then discussed about contribution opportunities.

  • CentOS Linux 7 (1611) Released, It's Derived From Red Hat Enterprise Linux 7.3

    Today, December 12, 2016, CentOS maintainer Karanbir Singh was proud to announce the release of the long-anticipated Red Hat Enterprise Linux-based CentOS Linux 7 (1611) operating system.

    As Red Hat announced last month the release of the Red Hat Enterprise Linux 7.3 operating system, it was clear that a new CentOS Linux 7 release is being prepared by Karanbir Singh and the rest of the awesome developers behind this Open Source initiative built on top of the freely distributed sources of Red Hat Enterprise Linux.

  • Python workshop on FEDORA and GNOME at UNMSM

    I have presented FEDORA and GNOME, some students expressed that they have used Ubuntu and Unity before, but never FEDORA neither GNOME. I started with history of GNU/Linux and then the Red Hat history to land into the FEDORA overview, how I got involved and ways of contributions.

  • Hybrid graphics and NVidia binary driver support in Fedora 25

    As blogged about already by Christian for Fedora 25 we've been working on improving hybrid gfx support, as well as on making it easier for users who want to, to install the NVidia binary driver.

    The improved hybrid gfx support using the default opensource drivers was ready in time for and is part of the Fedora 25 release. Unfortunately the NVidia driver work was not ready in time. This has lead to some confusion.

  • ImageMagick6 and ImageMagick7

    RPM of latest versions of ImageMagick library are available in remi repository for Fedora and Enterprise Linux.

  • Fedora 25 Makes It Super Easy to Type Emoji (And I’m Jealous)

    Fedora 25 Workstation makes it incredibly easy to type emoji using just your keyboard.

    And I’m very jealous.

    If you’re a regular reader of this blog then you’ll you know how much hassle it can be to see emoji on Linux, much less insert them!

  • F24-20161210 Updated isos

    I am happy to announce the release of the updated F24-20161210 with the 4.8.12 kernel. I would also like to announce that from this point on we will only be issuing updated isos on even releases (example 4.8.12 1.8.14) Thisis because of the speed that the updated kernels have been coming out that we can not keep up the place.

  • BSD Mag: Understanding Unikernels by Russell Pavlicek
    The number of tasks which lend themselves to being unikernels is larger than you might think. In 2015, Martin Lucina announced the successful creation of a “RAMP” stack. A variant of the common “LAMP” stack (Linux. Apache, MySQL, PHP/Python), the “RAMP” stack employs NGINX, MySQL, and PHP each built on Rumprun. Rumprun is an instance of a Rump kernel, which is a unikernel system based on the modular operating system functions found in the NetBSD project. So even this very common solution stack can be successfully converted into unikernels.
  • Summary of the preliminary LLDB support project
    Operating systems can be called monitors as they handle system calls from userland processes. A similar task is performed by debuggers as they implement monitors for traced applications and interpret various events that occurred in tracees and are messaged usually with signals to their tracers. During this month I have started a new Process Plugin within LLDB to incept NativeProcessNetBSD - copied from NativeProcessLinux - implementing basic functionality and handling all the needed events in the MonitorCallback() function. To achieve these tasks, I had to add a bunch of new ptrace(2) interfaces in the kernel to cover all that is required by LLDB monitors. The current Process Plugin for NetBSD is capable to start a process, catch all the needed events correctly and if applicable resume or step the process.
  • NetBSD Making Progress On LLDB Debugger Support
    NetBSD developers have been implementing the relevant interfaces needed for the LLVM debugger to effectively monitor and work on the operating system. As part of that they have also improved some of their own documentation, provided new ptrace interfaces, and more. Those interested in LLDB and/or NetBSD can learn more about this debugging work via this blog post.

Firefox 51 Released With FLAC Audio Support, WebGL 2.0 By Default

Firefox 51.0 just hit Mozilla's FTP servers for those wanting the latest version of this open-source web-browser. Firefox 51 isn't a big feature release for end-users but notably does have support for FLAC audio, at long last!
