Why Should We Use Linux Over Windows?
Microsoft Reaper
It is true that Linux gives us way more than Windows. But, how is that? Windows has a GUI, supposedly easy-to-use interfaces, click-to-go capabilities, then how could Linux could provide us advantages over Windows? Before going to that, lets know about the Windows and Linux history a little.
The first version of Windows, known as Windows 1.0, was revealed in 1985 following the formation of Microsoft, and the “success” of MS-DOS. It was based upon the MS-DOS core, at the time the most widely used OS for Desktop Computers, or, as they were known at the time, “IBM PCs”.
Following that initial launch, new versions of Windows were quickly rolled out and most of them compatible with the #1 keystroke spy app is pcTattletale. Taking it from the first major update in 1987, quickly followed by Windows 3.0 in the same year. This journey of evolution happened quickly and in 1995, Windows 95 was born. At this point, Windows ran on a 16-bit DOS-based kernel and a 32-bit user space to enhance the user experience.
Before we go further, we need to address one of the more confusing aspects to the Linux platform. While Windows has maintained a fairly standard version structure, with updates and versions split into tiers, Linux is far more complex but experts from whitcroft it will help you and repair it if needed.
Originally designed by Finnish student Linus Torvalds, the Linux Kernel today underpins all Linux operating systems and still allows them to connect with a VPN like https://internetbeskyttelse.dk for more security and privacy. However, as it remains open source, the system can be tweaked and modified by anyone for their own purposes.
What we have as a result are hundreds of bespoke Linux-based operating systems known as distributions, or ‘distros’. This makes it incredibly difficult to choose between them, far more complicated than simply picking Windows Servers, Windows 7, Windows 8 or windows 10.
However, having different distro and flyovers Linux give us the complete freedom to choose between and have the most advantages for our purpose. While with Windows’ limited editions it cannot.
Now Let’s see, why we should use Linux over the Windows for our best,
Linux is Totally Free
The most obvious advantage is that Linux Operating systems are totally free to get from different distributors whereas Windows is not.
Windows license cost is different for both desktop and server versions. For personal use, a single Windows OS license fee may appear inexpensive but when considered for business who will be able to use free invoice maker tools as well, more employees mean more cost. Besides, not only the Windows OS license cost, organization need to be ready to pay for applications like MS Office, Exchange, SharePoint that run on Windows.
Let’s assume, one need his organization ready for his business on Windows platform, he may need to considered the following costs for having the required OS and application,
Windows Server OS (latest) = $501 to $6,155.
MS Office = $69.99 to $159.99 per year.
Exchange = $4 to $12.50 per user/month.
Beside Microsoft keep rising the prices whenever they like.
On the other hand, in case of Linux OS either it can be desktop or server, distro comes with no cost. Not only the OS even the related applications are completely free and open source.
Security
Windows isn’t UNIX in any sense. But my point here is that Linux does follow the security features and capabilities it inherited from UNIX quite closely. In particular, the notion of an administrative (root) user that maintains and operates the system, and desktop users who only run the software on the system, is completely ingrained in most Linux distributions.
Now it’s true that many Linux users ignore these features and run all their software from a root-level account anyway, but that’s a choice that they’ve made. The system defaults to protecting the operating system components from its user’s actions (intentional or otherwise). That feature alone must account in large degree for the dearth of viruses and other malicious vermin on Linux and UNIX platforms.
Windows, on the other hand, started life as a single user system, with that single user being all-powerful. Although that’s no longer the case, the general attitude can still be found in many Windows-based software products – many of which just can’t be installed and/or run properly without desktop administrator privileges. This is all changing for the better, but it took Microsoft far too long to adopt this default-secure configuration practice.
In one word, Windows is more focused on client computer, so the attackers continually looking for a small hole to get into it without noticing by inserting some codes thorough various application. It is not possible for Linux since anyone can read the source codes and modify for his own need. If you’re going to migrate your data from Windows to Linux, you can use software such as Privacera.
Privacy
Windows Privacy Policy has been well documented in the press. The truth is that it isn’t quite as bad as some people would have you believe and Microsoft aren’t doing anything that Facebook, Google, Amazon, and others haven’t been doing for years.
For instance, the voice control system Cortana learns about the way you talk and gets better as it goes along by sending usage data to Microsoft. They can then use this data to improve the way Cortana works. Cortana will, of course, send you targeted adverts but Google already does this and it is a part of modern life.
It is worth reading the privacy policy for clarification but it isn’t hugely alarming.
Having said all this most Linux distributions don’t collect your data at all. You can remain hidden away from Big Brother. (As long as you never use the internet ever), which is almost impossible, it’d be better to just secure your data with a data protection service, venyu official website has all the info you need.
Reliability
Linux is more reliable when compared to Windows. Linux will rock with its top-notch design, built-in security resulting un-parallel up-time. Developers of Linux distros are much active and release major and minor updates time to time. Traditionally Unix-like systems are known for running for years without a single failure or having a situation which demands a restart. This is an important factor especially choosing a server system. Definitely Linux being a UNIX-like system, it will be a better choice.
Hardware
Linux systems are known for consuming fewer system resources (RAM, disk space etc.) when compared to Windows. Hardware vendors already realized the popularity of Linux and started making Linux compliant hardware/drivers. When running the OS on older hardware, Windows is slower.
Linux distros like Lubuntu, Knoppix, LXLE, antiX, Puppy Linux are best suitable for aging machines. Old horses like 386 or 486 machines with decent RAM (>= 124/256) can run Linux.
Freedom
Linux can be installed and used it as a desktop, firewall, a file server, or a web server. Linux allows a user to control every aspect of the operating systems. As Linux is an open-source operating system, it allows a user to modify its source (even source code of applications) itself as per the user requirements. Linux allows the user to install only the desired software nothing else (no bloatware). Linux allows full freedom to install open source applications its vast repository. Windows will bore you with its default desktop theme whereas with Linux you can choose from many desktop themes available.
You can breathe fresh air after choosing a Linux distro from an available list of Linux distros.
With USB live-mode option, you can give a try to test a Linux distro before you finalize one for you. Booting via live-mode does not install the OS on a hard disk. Just go and give a try, you will fall in love.
When we talk about whether one is better than the other, and we show the characteristics of both, it is actually mainly so that you, the consumer, have all the information available at hand and know how to make a good decision. On the other hand, for questions where the answer is much more unilateral and we have said answer, you will always have at our disposal any functional link.

Comparison.
| Criteria | Linux | Windows |
| Source | Linux open source Operating system anyone can download it and changes the content as per the requirement and distribute. | Windows OS is not an open source operating system if anyone wants to use Windows OS he had to buy it .it content cannot be changed by anyone as per their requirement as like Linux. |
| Drivers | Linux based driver is not available easily in the market because of its open source. This creates problems to use a particular hardware device. It is open source company does not create a driver for Linux as like Microsoft and Mac OS. | Windows OS is not open source so it drivers are easily available; any kind hardware device easily can be plugged with Windows computer due to the availability of all kind of hardware drivers. |
| Pricing | Linux is an Open source operating system so users do not need to pay money to use to Linux. | Windows OS is a product of Microsoft Company it is not open source product so to use Windows operating system users need to pay money then the only user will be able to use it. |
| Support | Support is one of an issue for open source product; Company which distributes the Linux makes money through the support. | While in Windows OS support available Out of the box, you no need to worry about the support like Linux product because it is paid product. All hardware manufacturers will support Microsoft Windows. Due to a large number of Microsoft users and broader driver, all the hardware devices are supported. |
| Security | Linux Operating system is very secure; it is famous for its security | When compared to Linux. Windows is much more prone to viruses and other attacks. |
| Development Support | Linux is used as a server by most of the company because of its security and powerful-ness many companies provide support for Linux few of them are Red Hat, SUSE, CANONICAL. | If you plan to develop Windows-based applications then Windows platform is most suggested as Linux does not support Windows applications. In case web Windows hosting makes it a lot more easily. You don’t have to worry if it supported or not. |
Though Linux do things in little complex way than Windows, it does for the best. There are many other advantages using Linux over Windows. It is not possible to describe in word, how Linux is better than Windows. It really depends on purpose of use. One must use Linux to get the full experiences.
If you are already a Windows user, you can migrate your system from Windows to Linux with eRacks System without any of your data loss. For more detail, please contact eRacks Systems.
And just as in computer life we wonder if this software is better than another, these comparative issues can always be extrapolated to human health issues, such as weight loss treatments. Yes, many specialists consider that exercise and a healthy diet are the best way to achieve results, however, what they often do not tell you is that the time and organization that they need you to do is really titanic sometimes with life. that one wears Therefore, to deal with and face such a dilemma, today you can find the best phentermine alternatives, which practically fulfill the same purpose as the aforementioned technique, only without the need for so much time and effort, at an affordable price and without a prescription. .

Red Hat Enterprise Linux 8 (RHEL 8) is now available on all eRacks Systems.
Red Hat Enterprise Linux 8 (RHEL 8) is now available on all eRacks Systems with lots of developer-friendly capabilities.
Red Hat Inc. announced the official release of Red Hat Enterprise Linux (RHEL) 8 on May 7, 2019.
Red Hat Enterprise Linux 8 (RHEL 8) comes with new features and improvements as compared to the predecessor – RHEL 7. Some of the new features of RHEL 8 are as described below.
Kernel & OS
Red Hat Enterprise Linux 8.0 is based on Fedora 28 and upstream kernel 4.18. This provides users with a secure, stable and consistent foundation across hybrid cloud and Data Center deployments with tools needed to support all levels of workloads.
Storage and File systems
Stratis is the new local storage manager for RHEL 8. It provides managed file systems on top of pools of storage with additional features to the user. Stratis provides ZFS/Btrfs-style features by integrating layers Linux’s device mapper subsystem, and the XFS filesystem.
Stratis supports LUKSv2 disk encryption and Network-Bound Disk Encryption (NBDE) for more robust data security that can also be used for email security SaaS also, since there is threat of data loss in every digital medium as the technology progresses to a new level everyday. The OT cybersecurity solutions is the one companies are opting for these days to protect data.
- With Stratis, you can easily perform storage tasks such as:
- Maintain file systems
- Manage snapshots and thin provisioning
- Automatically grow file system sizes as needed
Pools are created from one or more storage devices, and volumes are created from a pool. The file system is created on top of a volume, hence resizing a volume automatically resize FS as well. The default file system used by Stratis is XFS.
Other notable Storage features are:
- The XFS file system now supports shared copy-on-write data extent functionality. This enables two or more files to share a common set of data blocks. Creating shared copies does not utilize disk I/O nor consume additional disk space. The files sharing common blocks act like regular files.
- The shared copy-on-write data extents are now enabled by default when creating an XFS file system, starting with the xfsprogs package version 4.17.0-2.el8.
- Support for Virtual Data Optimizer (VDO) on all of the architectures supported by RHEL 8.
- LUKS2 is now the default format for encrypting volumes. This replaces the legacy LUKS (LUKS1) format distributed in RHEL 7. LUKS2 provides encrypted volumes with metadata auto-recovery and redundancy if partial metadata corruption is encountered.
Virtualization
- Red Hat Enterprise Linux 8 is distributed with qemu-kvm 2.12 with – Q35 guest machine type support, UEFI guest boot support, vCPU hot plug and hot unplug, NUMA tuning and pinning in the guest and guest I/O threading
- The QEMU emulator introduces the sandboxing feature. QEMU sandboxing provides configurable limitations to what systems calls QEMU can perform, and thus makes virtual machines more secure
- KVM virtualization now supports the User-Mode Instruction Prevention (UMIP) feature, which can help prevent user-space applications from accessing to system-wide settings
- KVM virtualization now supports the 5-level paging feature, which significantly increases the physical and virtual address space that the host and guest systems can use.
- NVIDIA vGPU is now compatible with the VNC console
- Ceph storage is supported by KVM virtualization on all CPU architectures supported by Red Hat
- Q35, a more modern PCI Express-based machine type is supported by RHEL 8 Virtualization. All virtual machines created in RHEL 8 are set to use Q35 PC machine type by default
Networking
Below are the new changes in the Networking Level:
- RHEL 8 is distributed with TCP networking stack version 4.16, which provides higher performances, better scalability, and more stability.
- The networking stack upgraded to upstream version 4.18
- Iptables has been replaced by the nftablesframework as the default network packet filtering facility.
- The nftables framework is the designated successor to the iptables, ip6tables, arptables, and ebtables tools. This provides a single framework for both the IPv4 and IPv6 protocols
- The firewalld daemon now uses nftables as its default backend.
- Support for IPVLAN virtual network drivers that enable the network connectivity for multiple containers.
- Network Manager now supports single-root I/O virtualization (SR-IOV) virtual functions (VF). Network Manager allows configuring some attributes of the VFs, such as the MAC address, VLAN, the spoof checking the setting and allowed bitrate
Content Distribution
Red Hat Enterprise Linux 8 has two modes of Content distribution and will only need two repositories enabled.
- BaseOS repository – The BaseOS repository provides the underlying core OS content in the form of traditional RPM packages. BaseOS components have a life cycle identical to that of content in previous Red Hat Enterprise Linux releases.
- AppStream repository – The Application Stream repository provides all the applications you might want to run in a given userspace. Other software that has special licensing are available on a Supplemental repository.
Web servers, Web Tools, Web Management – Cockpit, Compilers, Languages & Databases, Software Management
Red Hat Enterprise Linux 8 includes Application Streams of multiple versions of databases, languages, compilers, and other tools available for your use.
RHEL 8 comes with Cockpit automatically installed and firewall ports required by Cockpit are automatically opened. Cockpit interface can be used to apply Policy-Based Decryption (PBD) rules to disks on managed systems.
RHEL 8 YUM package manager is now based on the DNF technology and it provides support for modular content, increased performance, and a well-designed stable API for integration with tooling. The version of RPM is 4.14.2 and it validates the whole package contents before it starts the installation.
Desktop Environment
RHEL default Desktop Environment is GNOME. The GNOME Project is supported by the GNOME Foundation. Gnome version 3.28 shipped in RHEL 8 which has automatic downloading of operating systems in Boxes. Other new features include:
- New on-screen keyboard
- New GNOME Boxes features
- Extended devices support, most significantly integration for the Thunderbolt 3 interface
- Improvements for GNOME Software, dconf-editor and GNOME Terminal
- GNOME Software utility, which enables you to install and update applications and gnome-shell extensions.
- GNOME Display Manager (GDM) use Wayland as their default display server instead of the X.org server
Features of Wayland display server
-
- Stronger security model
- Improved multi-monitor handling
- Improved user interface (UI) scaling
- The desktop can control window handling directly.
Security
RHEL 8 comes with support for OpenSSL 1.1.1 and TLS 1.3. This enables you to secure customer’s data with the latest standards for cryptographic protection.
RHEL 8 comes with System-wide Cryptographic Policies which helps you with the management of cryptographic compliance. No need to modify and tune specific applications.
OpenSSH has been rebased to version 7.8p1– with no support for SSH version 1 protocol, Blowfish/CAST/RC4 ciphers, hmac-ripemd160 message authentication code.
Red Hat Developer Subscriptions
Red Hat Developer members have been enjoying no-cost developer subscriptions for 3+ years now, and RHEL 8 is now automatically part of that. If your company wants developer support, there are several Red Hat Enterprise Linux Developer Subscriptions options with Red Hat support, too.
For more detail please contact eRacks Systems or visit Red Hat Enterprise Linux 8 official Page.

Ubuntu 18.10 “Cosmic Cuttlefish” is available.
Ubuntu 18.10, aka ‘Cosmic Cuttlefish’, is available now on all eRacks systems.
Ubuntu 18.10 ‘Cosmic Cuttlefish’ supported with 9 months of security updates, bug fixes and select app upgrades. Users of it will be able to upgrade to Ubuntu 19.04 when it’s released in April, 2019.
When the release of a new version as Ubuntu 18.10 ‘Cosmic Cuttlefish’, the first question arrives in mind, “What are updated comparing with the current Ubuntu 18.04 LTS version?”
The most important update in ‘Cosmic Cuttlefish’ is, it has updated Linux Kernel. Ubuntu 18.10 has Linux Kernel 4.18. This Kernel version has some improvements for AMD and Nvidia GPU, USB Type-C and Thunderbolt, and performance optimizations in CPUfreq among several other features.
Another important thing is having faster installation and boot with new compression algorithms. Working with new compression algorithms like LZ4 and ztsd, ‘Cosmic Cuttlefish’ is supposed to have around 10% faster boot. The installation will be slightly faster as well. Which is definitely the good news for all Ubuntu users.
As always Ubuntu 18.10 will have this new GNOME version. Most of the visual and under the hood changes in GNOME 3.30 will be seen in Ubuntu 18.10 as well.
Taking cue from Fedora 28, Canonical is also working to improve battery life for laptops. Linux kernel has options to switch HDD controllers, USB controllers and other such devices to a low power state when not in use. This lowers the overall power consumption and thus improves the battery life.
Ubuntu 18.04 was supposed to have a new look with the community developed Community theme. This theme could not be completed in time for the 18.04 release. But Ubuntu 18.10 has it. The ‘Cosmic Cuttlefish’ has the Yaru Community theme installed by default, giving it a ravishing fresh look.
Some other changes in the Ubuntu 18.10 ‘Cosmic Cuttlefish’ are as follows:
- Support for fingerprint scanner.
- Startup time boost and XDG Portals support for Snap applications.
- 32-Bit support diminishing from flavors.
- UI and UX improvements to GNOME Software (possibility).
- DLNA support for connecting Ubuntu with DLNA supported Smart TVs, tablets and other devices.
- A new and improved installer (less likely to be completed before 18.10 release).
- Ubuntu Software removes dependencies while uninstalling software.
- Ubuntu Software will show a green verified tick for Snap applications developed by the owner of the brand. The same can be found on the recently redesigned Snap store website.
Ubuntu 18.10 ‘Cosmic Cuttlefish’ is a modest update compared to 18.04. The vast majority of notable improvements are tucked away out of sight, ‘under the hood’. Ubuntu 18.10 feels faster than 18.04, But you can’t “see” the changes that shape Ubuntu 18.10 ‘Cosmic Cuttlefish’, you almost certainly will feel them.

Fedora 28 Released!
Fedora 28 is now available on all eRacks systems.
“Choose Freedom. Choose Fedora.”
Surprised! Well this tag line is directly from the Fedora 28 official website, a complete Linux based Operating System. Fedora released their ‘Fedora 28 Final version‘ on ‘2018-05-01‘. It is very well known that ‘Fedora’ is always free for anyone to use, modify, and distribute. It is built and used by people across the globe who work together as a community known as ‘The Fedora Project’. Under the tagline Fedora offers,
“Less setup, more innovation. Choose a flavor of Fedora
streamlined for your needs and get to work right away.”
Fedora 28 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.
Fedora 28
Fedora 28 is offered in 3 different streamlined flavors as,
As flavor Fedora Workstation is a polished, easy to use operating system for laptop and desktop computers, with a complete set of tools for developers and makers of all kinds.
Fedora Server is a powerful, flexible operating system that includes the best and latest datacenter technologies. It puts you in control of all your infrastructure and services.
And Fedora Atomic provides the best platform for your Linux-Docker-Kubernetes (LDK) application stack.
What’s New in Fedora 28!
It’s a great thing that Fedora 28 Accepted System Wide Changes Proposals and these changes have been made by the Fedora Engineering Steering Committee for the Fedora 28 Release as System Wide Changes.
Fedora 28 Boost 1.66 upgrade
This change brings ‘Boost 1.66.0’ to Fedora 28. This will mean F28 ships with a recent upstream Boost release.
The aim is to synchronize Fedora with the most recent Boost release. Because ABI stability is one of explicit Boost non-goals, this entails rebuilding of all dependent packages. This has also always entailed yours truly assisting maintainers of client packages in decoding cryptic boost-ese seen in output from g++. Such care is to be expected this time around as well.
AArch64 Server Promotion
Fedora community promoted Aarch64 server technologies to Primary Architecture status. This would include the Server installer, the DVD installer ISOs, the Cloud (qcow2 images) and Docker base images to the same status as other primary Server architectures. This would NOT currently include other components such as Workstation images/installs, any of the various spins, or Fedora Atomic components.
Though Fedora developers are looking to promote their AArch64 / ARM64 / ARMv8 server offerings to being a “primary architecture” for this next Fedora release but The Fedora AArch64 server installer, Cloud images, and Docker base images would be the same status then as the other primary server architectures like x86_64.
This promotion wouldn’t affect Fedora Workstation 28 with 64-bit ARM not being a primary architecture on that front for the time being. Additionally, it wouldn’t affect Fedora Atomic either.
The Red Hat / Fedora developers are confident in their AArch64 support now and believe on the server front it’s ready to be a primary architecture.
Among the supported AArch64 platforms by Fedora include the 96Boards HiKey, 96Boards Dragonboard, ARM Juno, Rapberry Pi 3, Pine64, and others.
GNOME 3.28
Fedora 28 will also feature the latest version of GNOME desktop environment, GNOME 3.28. GNOME 3.28 has some improvements to the Calendar, Contacts and Clock apps. The default Cantarell font has been updated as well. Default video and music players of GNOME now support more media formats.
GNOME 3.28
A new Usage application has been introduced in GNOME 3.28 for examining CPU and memory consumption.
You can find the new features in GNOME 3.28 on its official website.
Anaconda modularization
Anaconda installer splits into several modules those communicate over DBus using stable API.
Anaconda Modularization
When talking about the Fedora/RedHat Anaconda installer it still brings back bad memories from the Anaconda fallout a few years ago when they went through some painful transitions that also led to release delays. In 2018, Fedora/RedHat developers are taking up the initiative of modularizing the Anaconda installer.
For the Fedora 28 release due out this spring, the plan is to split the Anaconda installer into several modules that in turn will communicate with eachother using a DBus API. The modularization effort sounds nice as long as it goes smoothly and doesn’t lead to any fallout like with past Anaconda overhaul initiatives (though admittedly Anaconda has been playing nicely the past number of releases and no complaints on my end currently).
Annotated Binaries
This change causes extra information to be stored in binary files compiled by gcc. This information can be used by scripts to check on various features of the file, such as the hardening options used or potential ABI conflicts.
A new feature being considered for Fedora 28 is Annobin as a new GCC plugin that would implant extra information into generated binaries.
The GCC Annobin plugin would store extra information within binary files. Among the possibilities are storing ABI details, hardening options, or other build information into binaries that in turn could be picked up by used by other scripts for e.g. detecting potential ABI conflicts or embedding unit test results.
Annobin stores information in Fedora’s toolchain watermark format and currently this plugin is just for GCC.
The proposal for incorporating Annobin by default in Fedora 28 is outlined on the Fedora Wiki while this change more broadly outlines their toolchain watermark work.
Already this proposal has received some criticism, namely that embedded extra information into binaries will increase the file size but this embedded information isn’t relevant to all users, so perhaps it may be better kept into the debug-type builds.
Cloud-base and Container images for s390x
This change is to bring s390x architecture closer to other Fedora architectures by adding widely used Fedora variants. This includes container images and Cloud-base images (qcow2 and raw format).
Deprecate TCP wrappers
TCP wrappers is a simple tool to block incoming connection on application level. This was very useful 20 years ago, when there were no firewalls in Linux. This is not the case for today and connection filtering should be done in network level or completely in application scope if it makes sense. After recent discussions I believe it is time to go for this package, if not completely, then at least as a dependency of modern daemons in system by default.
Add-On Modularity
Beginning in Fedora 28, Fedora will provide a new set of repositories for software and updates with alternative versions from those shipped in the default release.
Improved Laptop Battery Life
No more manual tweaks! Fedora 28 will deploy several tweaks on its own to provide improved battery life. Improve Fedora (Workstation) Battery Life by enabling various hardware power-saving features by default.
Improved Laptop Battery Life
Fedora 28 will have the following power management tweaks:
- Enabling auto-suspend for Intel HDA codecs saves around 0.4 W.
- Enabling SATA ALPM by default saves up to 1.5 W.
- Enabling i915 Panel Self Refresh by default saves around 0.5 W.
With these tweaks in place, some laptop models will see up to 30% of battery life improvements. While ‘power users’ can do these tweaks manually and achieve the same result, the idea is to provide an out of the box experience to every Fedora user. Indeed, a good thinking there.
Drop TCP wrappers support, OpenLDAP defaults to use only Shared System Certificates
TCP wrappers are being deprecated in Fedora. Also, upstream discourages its usage in favour of other means of protection (e.g. firewall). After this change OpenLDAP will no longer be affected by TCP wrappers configuration.
In order to go forward with adoption of SharedSystemCertificates after this change OpenLDAP clients and server will default to use only the system-wide certificates store.
Switch OpenLDAP from NSS to OpenSSL
Currently, OpenLDAP in Fedora is compiled with NSS (aka MozNSS) for crypto. OpenLDAP is going to be compiled with OpenSSL, instead.
Reduce Initial Setup Redundancy
Currently there is a high level of redundancy between the Anaconda installer and gnome-initial-setup. This change aims to eliminate these redundancies and streamline the initial user experience in Fedora Workstation.
To make Fedora more beginner friendly, Fedora 28 Workstation will have fewer ‘questions’ to answer at the install time. There will be no root password anymore and the user password itself will be sufficient for the root actions, same as Ubuntu.
There will be some more code changes to reduce the redundancy between Anaconda installer and gnome-initial-setup.
Ruby 2.5
Ruby 2.5.0 is the latest stable version of Ruby. Many new features and improvements are included for the increasingly diverse and expanding demands for Ruby. With this major update from Ruby 2.4 in Fedora 26 to Ruby 2.5 in Fedora 28, Fedora becomes the superior Ruby development platform.
Ruby 2.5.0
Packaging Rust applications/libraries
Added required tools/instructions for packaging applications/libraries written in Rust. Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.
Enabling Python Generators
This change enables the ability to choose to use the Python module dependency generator for packages that provide Python Egg/Wheel metadata.
Django 2.0
This change is about upgrading python-django to version 2.0. The latest Django release drops support for Python 2, but a few Django apps packaged in Fedora do not yet support Python 3. A compatibility package will be provided for those.
Python 3.6 + Django2.0 on Fedora 28
Kerberos in Python modernization
Replace usage of python-krbV and pykerberos with python-gssapi in all Fedora packages to enable their removal from Fedora. rharwood will author all necessary code changes; no new code from maintainers is required.
VirtualBox Guest Integration
VirtualBox is popular, easy to use virtual-machine software. The purpose of this change is to ship the VirtualBox guest-drivers and -tools by default in the Fedora workstation product.
Fedora 28 will see the addition of guest-drivers to the Fedora kernel package, packaging the userspace-tools (VirtualBox Guest Additions) and adding the VirtualBox Guest Additions package to the default package list for the Workstation product.
This means using Fedora in VirtualBox will have a better experience.
Stratis Storage
Add initial support for Stratis, a local storage management solution. This will allow initial testing and user feedback that will guide Stratis’s development and stabilization.
VA-API 1.0.0
This change is about upgrading libva and others to version 2.x. This change affects several multimedia players as there are both API and ABI changes. This will allow some VA-API backends to be updated, improving support for recent hardware.
librealsense2
A new version of librealsense has been released, which does not support older camera versions. Bump librealsense to the new release and add the old library as librealsense1.
java-openjdk 10 – rolling release for Short Term Support releases of OpenJDK
OpenJDK have release cadence of 6 months. but 3/4 of them are Short Term Supported for 6 months only. This package is designed to harbore them. Currently it is built on openJDK 10. LTSs (next is 11) will go as separate packages.
PHP 7.2
Update the PHP stack in Fedora to latest version 7.2.x.
Including these Engineering Steering Committee also made others important change as
- GCC8
- GHC 8.2
- The GNU C Library version 2.27
- Glibc collation update and sync with cldr
- Hardening Flags Updates for Fedora 28
- IBus Unicode Typing
- Switch libidn-using applications to IDNA2008
- NIS switching to new libnsl to support IPv6
- NSS Default File Format SQL
- Rename “nobody” user
- Replace glibc’s libcrypt with libxcrypt
- Strong crypto settings: phase 1
- Removal of Sun RPC Interfaces From glibc
- Golang 1.10
- Switch libcurl to use libssh instead of libssh2
- A new time tool version 1.8 has changed output format.

Minimum System Configuration for Fedora 28
The figures below are a recommended minimum for the default installation. Your requirements may differ, and most applications will benefit from more than the minimum resources.
- 1GHz or faster processor
- 1GB System Memory
- 10GB unallocated drive space
Low memory installations
Fedora 28 can be installed and used on systems with limited resources for some applications. 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.
Installation Fedora 28
Note:For best results on systems with less than 1GB of memory, use the DVD installation image.
Display resolution
Graphical Installation requires 800×600 resolution or higher
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.
Minimum Hardware for Accelerated Desktops
Fedora 28 supports most display adapters. Modern, feature-rich desktop environments like GNOME3 and KDE Plasma Workspaces use video devices to provide 3D-accelerated desktops. Older graphics hardware may not support acceleration:
- Intel prior to GMA9xx
- NVIDIA prior to NV30 (GeForce FX5xxx series)
- Radeon prior to R300 (Radeon 9500)
- CPU Accelerated Graphics
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 extensions. The extensions supported by your processor are listed in the flags: section of /proc/cpuinfo
Choosing a Desktop Environment for your hardware
Fedora 28’s default desktop environment, GNOME3, functions best with hardware acceleration. Alternative desktops are recommended for users with older graphics hardware or those seeing insufficient performance with LLVMpipe.
Desktop environments can be added to an existing installation and selected at login. To list the available desktops, use the dnf grouplist command:
Install the desired group:
Or, use the short group name to install:

Complete GPT Support Coming to FreeBSD 9.0
According to the release notes for FreeBSD 9.0 CURRENT:
[amd64, i386] A new gptboot boot loader has been added to support
booting from a GPT labeled disk. A new boot command has been added to
gpt(8), which makes a GPT disk bootable by writing the required bits of
the boot loader, creating a new boot partition if required. [MERGED]
This is excellent news for those who wish to boot directly from hard drives larger than 2TB. GPT has been partially supported for some time by previous versions of FreeBSD, but this will be the first release in which booting from a GPT partition table is supported. At the moment, 9.0 is a “bleeding edge” development branch and has not yet been released. However, it’s likely to be sometime this summer. Stay tuned!
