Making the world safe for Open Source

    Fedora (formerly Fedora Core) is a Unix-like operating system based on the Linux kernel and GNU programs (a Linux distribution), developed by the community-supported Fedora Project and sponsored by the Red Hat company. Fedora contains software distributed under various free and open-source licenses and aims to be on the leading edge of such technologies. Fedora is the upstream source of the commercial Red Hat Enterprise Linux distribution.

Since the release of Fedora 21, three different editions are available: Workstation, focused on the personal computer, Server and Cloud for servers, and Atomic being the edition meant for cloud computing. As released on July, 11, 2017 they introduced Fedora 26!

fedora26

Fedora 26 has arrived with thousands of improvements to development tools, partitioning tools, better caching of user and group information, better debugging, an improved DNF package manager, and so much more.

Let’s see some of many upgraded System Requirements & features, those are new Fedora 26 offering.

Minimum System Requirements

Fedora 26 provides software to suit a wide variety of applications. The storage, memory and processing requirements vary depending on usage. For example, a high traffic database server requires much more memory and storage than a business desktop, which in turn has higher requirements than a single-purpose virtual machine. Your requirements may differ, and most applications will benefit from more than the minimum resources.

Fedora 26 recommended minimum System Configuration for the default installation are as follows:

  • 1GHz or faster processor
  • 1GB System Memory
  • 10GB Usable Drive Space

Fedora 26 can be installed and used on systems with limited resources. Text, VNC, or kickstart installations are advised over graphical installation for systems with very low memory. Larger package sets require more memory during installation, so users with less than 768MB of system memory may have better results preforming a minimal install and adding to it afterward.

For best results on systems with less than 1GB of memory, one should use the DVD installation image. Fedora also give us some guidelines for it’s best practices and performances.

  • Graphical installation of Fedora requires a minimum screen resolution of 800×600. Owners of devices with lower resolution, such as some netbooks, should use text or VNC installation. Once installed, Fedora will support these lower resolution devices. The minimum resolution requirement applies only to graphical installation.

  • Fedora 26 supports most display adapters. Modern, feature-rich desktop environments like GNOME3 and KDE Plasma Workspaces use video devices to provide 3D-accelerated desktops. Systems with older or no graphics acceleration devices can have accelerated desktop environments using LLVMpipe technology, which uses the CPU to render graphics. LLVMpipe requires a processor with SSE2.

 

Features

Fedora 26 offers latest GNOME 3.24, LibreOffice 5.3, Fedora Media Writer, Improved Qt app compatibility & so on…

GNOME 3.24

gnome-3-24

Newest version of the GNOME desktop now has a Natural Light Filter feature that changes display’s color temperature. It works based on the time of day and helps prevent sleeplessness and eye strain. Also, there are updates to the Settings panel for online accounts, printers, and users. The notifications area sports a cleaner, simpler layout, with integrated weather information.

For developers, Builder now features improved support for systems like Flatpak, CMake, Meson, and Rust. It also integrates Valgrind to help profile your project. There are numerous other improvements, which you can find in the GNOME 3.24 release notes.

 

LibreOffice 5.3

The latest version of the popular office suite features many changes. It includes a preview of the experimental new NotebookBar UI. There’s also a new internal text layout engine to ensure consistent text layout on all platforms.

 

Fedora Media Writer

The new version of the Fedora Media Writer can create bootable SD cards with Fedora for ARM devices such as Raspberry Pi. It also features better support for Windows 7 and screenshot handling. The utility also notifies you when a new release of Fedora is available.

 

Improved Qt app compatibility

The Adwaita theme contains many improvements and looks closer to its GTK counterpart than ever. There are also two variants ported to Qt, dark and high contrast. If you switch to dark or high contrast Adwaita, your Qt apps will switch as well.

 

            Matthew Miller, Fedora Project Leader, wrote in a Fedora Magazine post about Fedora 26. As he wrote “First, of course, we have thousands of improvements from the various upstream software we integrate, including new development tools like GCC 7, Golang 1.8, and Python 3.6. We’ve added a new partitioning tool to Anaconda (the Fedora installer) — the existing workflow is great for non-experts, but this option will be appreciated by enthusiasts and sysadmins who like to build up their storage scheme from basic building blocks. F26 also has many under-the-hood improvements, like better caching of user and group info and better handling of debug information. And the DNF package manager is at a new major version (2.5), bringing many new features. Really, there’s new stuff everywhere — read more in the release notes.”

 

Among the current Fedora users, most of may wish to go straight for the clean install—which makes perfect sense and always winds up with a reliable and stable instance.

As with release of latest version of Fedora, we offer latest Fedora 26 with our systems as pre-configured according to your custom quote…

Mozille BrowserID / Persona Dies

A Sad Day – Mozille BrowserID / Persona Dies

It’s a sad day – the best of the federated Authentication Providers, without its own agenda or privacy issues, has shut down, due to the public’s apparent lack of interest and / or awareness.

Mozilla Persona, which started life several years ago as BrowserID, was the only one of the OpenAuth-based Authentication providers that didn’t insist on being logged in to a commercial site in order to be authenticated by proxy at the time – with all the privacy issues that entails.

Although it’s no secret that The Public is notorious for not caring about (or not even being aware of) privacy (or at least sacrificing it in favor of convenience), it’s unfortunate that the Mozilla Foundation has chosen not to spend the time, effort, and money to educate the public, as it has chosen to do with its other products.

Here are some relevant excerpts from the shutdown page:

FAQs

A website I use requires Persona for login, what should I do?

You will need to contact the site owner and ask about their plans for migrating away from Persona.

Mozilla staff can find more information about the progress of migrating internal sites on this mana page.

Why is persona.org being shut down?

Our metrics show that usage of persona.org is low, and has not grown over the last two years.

Hosting a service at the level of security and availability required for an authentication system is no small undertaking, and Mozilla can no longer justify dedicating limited resources to this project. We will do everything we can to shut it down in a graceful and responsible manner.

What will happen in the meantime?

Between now and November 30th, 2016, Mozilla will continue to support the Persona service at a maintenance level: Security issues will be resolved in a timely manner and the services will be kept online, but we do not expect to develop or deploy any new features. Support will continue to be available on the dev-identity mailing list and in the #services-dev IRC channel.

All websites that rely on Persona will need to migrate to another means of authentication during this time.

What happens after that?

On or after November 30th, 2016, the services hosted by Mozilla on persona.org will be taken offline. This includes the persona.org website, the javascript shim, the fallback IdP and identity bridges, and the hosted verifier.

Mozilla will retain control of the persona.org domain and will not transfer it to a third party. This is a security measure to protect websites that have not completed their migration away from the service.

All user data stored on the persona.org services will be destroyed, including registered email addresses and password hashes. Since the privacy of user data is of utmost importance to Mozilla, we will not transfer it to any third parties.

What about the code?

All of Persona’s code — core, bridges, shims, and more — is open source and remains available on github. Though this marks the end of Mozilla’s direct involvement in Persona, we encourage others to continue learning from and building upon our work.

Migration Suggestions and Guidelines

The following alternative login options are available for sites migrating away from Persona. We will continue to update this page throughout the year.

We intentionally designed Persona to expose email addresses rather than opaque identifiers, which should ease the transition to other systems that provide verified email addresses.

Mozilla-hosted sites may find additional, staff-login-specific migration options on the internal mana page.

Delegated Authentication Providers

Many large email and service providers offer delegated login for third-party applications, including Google, Facebook and GitHub. Indeed, we have found that many sites currently using Persona also offer login via one or more of these services. While these services do not offer equivalently-strong privacy guarantees to Persona, they are a convenient and secure choice for users since they avoid the creation of a site-specific password.

We plan to offer delegated authentication with Firefox Accounts some time in 2016. If you’re interested in adding Firefox Accounts as a login option to your site, please reach out to us on the dev-fxacct mailing list.

Site-Specific Accounts

Many web frameworks offer password-based user accounts functionality out-of-the-box. Although it requires users to create and remember yet another password, it can be a good choice for users who do not have (or do not wish to share) an account with a delegated authentication provider.

For existing users who previously authenticated with Persona, you could consider authenticating them through Persona again to confirm their email address, then prompting them to create a site-specific password.

Passwordless Email Login

As an alternative to setting a site-specific password, you can allow users to login directly via email link, as described in this article and implemented by libraries like passwordless. This can avoid the security implications of users having to create and manage another password, and may be a good fallback option when used in combination with delegated authentication providers.

Self-hosting Persona

Since the code for Persona is open-source, it would be possible for reliers to self-host an instance of the service that is dedicated to their own use.

This approach is not recommended most reliers. Persona has a large and complex codebase that has not seen significant development in several years, and Mozilla will not provide security or maintenance updates after 30th November 2016.

More?

We encourage affected reliers to document any alternative solutions here and to discuss them on the dev-identity mailing list, so that others can benefit from their experience.

  • The Portier open source project attempts to replicate much of Persona’s user experience, while being easy to self-host, even on the free tier of PaaS providers like Heroku. Similar to Persona, Portier supports identity-bridging to Gmail. It falls back to passwordless-style login links for everyone else.

Taken from:

https://wiki.mozilla.org/Identity/Persona_Shutdown_Guidelines_for_Reliers

 

We at eRacks wil be looking into Portier for our own usage, as well.

cinnamon-mint-18Linux Mint 18 is now available!

Based on Ubuntu 16.04, which was made available in April, this release of Mint is based on the LTS release of Ubuntu, rather than following the twice-yearly updates – and will have only incremental changes and updates over the next 2 years – thus being more stable and predictable, and avoiding any potential instabilities introduced by the biannual Ubuntu upgrades.

So Mint 18 should now be available in all the eRacks product dropdowns – if you don’t see it on the model you want, please contact us and we’ll fix it or give you a custom quote with Mint 18.

As always, contact us at info@eracks.com for any inquiries or questions regarding the Mint 18 release, or any of our products, and what release we recommend for you and your unique needs.

eRacks/NAS50 Half Petabytes of Data Storage Server / Cloud Storage

eRacks/NAS50 Half Petabytes of Data Storage Server / Cloud Storage

We were extremely excited to announce the forthcoming release of 500 Terabyte (half Petabyte) storage space upgrade on our flagship product eRacks/NAS50 cloud data storage servers last week.  The new model, to be released shortly, will incorporate 50 HGST 10 Terabyte HelioSeal™ hard drives.  While the new model is not released yet, we are accepting pre-orders from customers.  The current capacity, now available, of the eRacks/NAS50 is 400Terabytes in total, with currently-available 8Terabyte drives.

The new unit is rackmount and holds 50 removable drive bays.  The 9U unit is suitable for any cloud storage application as well as NAS/Local LAN.  eRacks/NAS50™ is also a great solution for media libraries and other applications which require massive amounts of data storage capacity.

Our new servers are truly a remarkable Petascale solution.  The HGST 10 Terabyte HelioSeal™ drives that come with eRacks/NAS50 use two technologies that greatly add to the value that this server carries with it.

The first is referred to as the HelioSeal™ technology.   The HGST hard drives using this technology replace the air inside of the drive with helium.  This would make the drive much lighter as well as allowing the disks to be much thinner.   Due to the helium inside, the thinness of disks will not cause any disruptive turbulence effects.  This will allow us to have more disks inside each drive which in turn means more data space.  Additionally, helium drives have much lower power consumption, as much as 27%, making our NAS50 models truly a green product.

The new drives in the eRacks/NAS50 servers also make use of a technology called SMR.  That is short for Shingled Magnetic Recording.  This technology by itself adds another 25 to 100 percent storage capacity to HGST hard drives.

We are proud of our new eRacks/NAS50 and are ready to take pre-orders.  We are prepared to customize the unit per your instructions with all Open-Source software necessary so your order will reach you completely pre-installed.

Please contact us for pre-orders or any questions you may have.

eRacks/NAS36 Front

eRacks Open Source Systems announces the immediate availability of the eRacks/NAS36 rackmount storage server, with 36 removable 6TB hard drives, which yields a maximum of 216TB (Terabytes*) of raw storage with current widely-available technology. The eRacks/NAS36 rackmount server is shipped pre-configured to the user’s custom specs, with any available open-source software, and more flavors of Linux or BSD available than any other vendor.

Fremont, CA (PRWEB) October 3, 2014

eRacks Open Source Systems is pleased to announce the latest upgrade eRacks/NAS36 rackmount storage server.

Available immediately, it combines a rack usage of only 4U with a density of 36 drives (24 front and 12 rear), which, when combined with the current technology of widely available 6TB drives, yields a total storage of 216TB*.

This rounds out eRacks’ line of rackmount multi-drive storage servers and NAS solutions, nicely filling the gap between the 24-drive eRacks/NAS24 and the all-front-loading 50-drive eRacks/NAS50, eRacks’ flagship storage server.

When populated with 36 removable drives in only 4U, this represents a density / price breakthrough – using the best value (lowest price/TB) 6TB drives, this enables 216TB* of raw storage in only 4U, and for less than $30,000, as configured on the eRacks website.

The unit is also available partially populated, at a reduced price, to make it accessible at a lower initial price, and the storage can be increased later by filling the empty drive trays.

It’s signature service, eRacks will be happy to install any of the popular Linux distributions on request – Ubuntu, Debian, RedHat, Centos, Fedora, even the Arch Linux distro, which is growing fast in popularity, as well as FreeBSD, OpenBSD, or other Open Source OSes.nas36-both

eRacks will also pre-install any open source NAS software, such as FreeNAS, OpenFiler, NAS4Free and OpenMediaVault, among others – and administrative dashboards and web GUIs are offered on most of these software choices.

Also available is OpenStack, and other OSS cloud software, such as Eucaluyptus or CloudStack, as well as best-of-breed Open Source software for BigData / Cloud storage, NAS, and networking – including Hadoop, MooseFS, CIFS, GlusterFS, etc – and eRacks is a partner with MooseFS.org.

In addition, the eRacks policy is to install any Linux/BSD distro or Open Source software on request – Contact eRacks today at http://eracks.com/contact to see how they can meet your needs.

Please email info@eracks.com to request a custom quote.

 

Note: *For the purposes of this press release, the term “Terabyte” is used to mean one trillion bytes – eRacks understands the issues about this, we are using the term as the disk drive and other industry manufacturers use it.
