Open Source Experts Since 1999

The Ubuntu 20.10 code name Groovy Gorilla, Yes, “Groovy Gorilla” is the development code name chosen for the next stable Ubuntu release, which is currently earmarked for general availability on October 26, 2020.

Now, I probably don’t need to tell you what a gorilla is — and if you don’t know, I don’t believe you !!, and the term groovy is… Well, the dictionary definition of “Groovy” describes it as an informal adjective meaning ‘fashionable and exciting’, e.g., “That’s a groovy new wallpaper!” or generally ‘excellent, e.g., “A groovy release filled with greatness”.

Ubuntu 20.10 establishes another milestone in Canonical’s long-term commitment to delivering a carrier-grade private cloud with “Groovy Gorilla”. The 33rd release of the most popular Linux distribution in the data center space, Groovy Gorilla, brings various improvements that enable easier consumption of the fast-networking stack across both VMs and containers, straightforward compliance with common security benchmarks and a reference telco cloud implementation.

Ubuntu 20.10 “Groovy Gorilla” is a short-term release supported for 9 months until July 2021. So, with its imminent release on 22nd Oct 2020, Ubuntu 20.10 will be getting support from Canonical till July 2021. This includes access to new app releases, bug-fixes, and security patches. This release mostly the testbed for the latest application, Kernel stack to provide users stable packages back to Ubuntu 20.04 LTS.

I personally have been using it for the past couple of days, and it’s reasonably stable. It also feels snappier compared to its predecessor, which isn’t a surprise considering it was primarily focusing on performance enhancements.

That being said, I won’t keep you waiting with the formalities. I know you came here to get a tour of what’s new with Ubuntu 20.10, and I have put together a few new changes in Ubuntu 20.10. Only you can feel the exact changes when you start using it.

let’s what’s new in latest Ubuntu 20.10 “Groovy Gorilla”;

 

Ubuntu 20.10 “Groovy Gorilla” Some Major Features:

Linux Kernel 5.8

When development for Ubuntu 20.10 started, it was based on Ubuntu 20.04 and used the same kernel base – Linux kernel 5.4 LTS. But then, Linus Torvalds released Linux kernel 5.8 in May, and everyone in the Linux community was suspecting that “Groovy Gorilla” will ship with it.

Now, after a long wait, the Linux 5.8 kernel has popped up in the Ubuntu 20.10 archives, and that too only a month ago. This means that the new iteration of the popular Linux distro will benefit from the sweep of features that comes with the new kernel.

Some notable examples include:

  • Airtime Queue limits for better WiFi connection quality
  • Btrfs RAID1 with 3 and 4 copies and more checksum alternatives
  • USB 4 (Thunderbolt 3 protocol) support added
  • X86 Enable 5-level paging support by default
  • Intel Gen11 (Ice Lake) and Gen12 (Tiger Lake) graphics support
  • Initial support for AMD Family 19h (Zen 3)
  • Thermal pressure tracking for systems for better task placement wrt CPU core
  • XFS online repair
  • OverlayFS pairing with VirtIO-FS
  • General Notification Queue for key/keyring notification, mount changes, etc.
  • Active State Power Management (ASPM) for improved power savings of PCIe-to-PCI devices
  • Initial support for POWER10

 

Easy Wi-Fi Hotspot Configuration

The Wi-Fi tab in “Settings” allows you to use your laptop as a Wi-Fi hotspot. If you scan the QR code with a mobile device, like your smartphone or tablet, it will connect to your hotspot.

 

Security Improvements

  • nftables is now the default backend for the firewall.

 

Ubuntu 20.10 Desktop

  • Ubuntu 20.10 is the first Ubuntu release to feature desktop images for the Raspberry Pi 4.

 

GNOME 3.38

Ubuntu 20.10 is shipping with GNOME 3.38 out of the box, released on 16th Sept 2020. It is a welcome upgrade over GNOME 3.34, which is being used in Ubuntu 20.04 by default.

 

GNOME 3.38 brings many excellent features and functionalities to the table. Here is a list going over the most notable ones:

  • Better Fingerprint Support
  • Intelligent Web Tracking Prevention
  • Updated GNOME Maps with Performance and UI Improvements
  • A Redesigned Sound Recorder and Screenshot App
  • Support for QR Code WiFi Hotspot
  • Tons of New Default Wallpaper
  • Folder Support in Application Grid
  • Restart Button Added to System Tray
  • New Icons for Various Apps
  • New Parental Controls Under Settings

Apart from this, you will get to see many more bells and whistles. We have a detailed article covering the best features in GNOME 3.38 if you are looking for more information.

Now, as you know, Ubuntu is not known for shipping with vanilla GNOME. As such, you won’t get the authentic experience that was intended by the GNOME developers. We will talk more about the new interface and overall end-user experience in a later section.

 

ZFS Becomes Less Experimental

The Ubuntu Unity installer hasn’t changed significantly. The installation process is almost the same as it was on Ubuntu 20.04, and the black disk checking screen is the same.

 

One notable change is tucked away in the “Advanced Features” dialog box. The ZFS file system installation option no longer has the word “Experimental” in capital letters beside it. Confidence must be building within Canonical about the durability and readiness of its ZFS implementation as a daily driver file system.

After you install Ubuntu 20.10 and sign in, you’ll see the Groovy Gorilla, positioned prominently amidst the familiar purple hues of the Ubuntu color palette.

He looks like an ape that’s got it together, but let’s see if that’s true.

Updated Applications:

  • Firefox version 81
  • LibreOffice version 7.0.2
  • Thunderbird version 78.3.2

Updated Subsystems:

  • BlueZ 5.55
  • NetworkManager 1.26.2

Noteworthy changes Ubuntu 20.10 Server:

  • squid: the NIS basic authentication helper was removed (LP: #1895694 34)
  • adcli and realmd: many upstream fixes were applied to these packages, improving on the compatibility with current Active Directory changes
  • samba 4.12 40 has switched to GnuTLS for most of its cryptographic operations and that has a huge performance improvement in SMB3 encryption
  • QEMU was updated to the 5.0 release. See the upstream changes 40 for an overview of the many improvements.
  • One noteworthy new feature is virtiofs 42 which allows better sharing of host file systems to the guest compared to the older 9p fs 4 based approach.
  • Libvirt has been updated to version 6.6. See the upstream Changelogs 34 for the many improvements and fixes since version 6.0 that was in Focal.
  • Libvirt 6.6 also supports the new virtiofs that was mentioned in the QEMU section above.

 

System Requirements for Ubuntu 20.04:

  • 2 GHz dual-core processor
  • 4 GiB RAM (but 1 GiB can work)
  • 25 GB of hard-drive space
  • VGA capable of 1024×768 screen resolution
  • Either of the two: a CD/DVD drive or a USB port for the installer media

Note: Optionally, Internet access is helpful.

 

Download Ubuntu 20.10

You can download Ubuntu 20.10 for 64-bit computers using the link below:

As the Ubuntu 20.10 desktop image is 2.9GB in size do make sure you’re on a decent internet connection before you hit the download button!

When the download completes you need write the Ubuntu 20.10 ISO image to a USB stick using a tool like Etcher. Then pop the USB in an empty port, reboot your computer, and choose to boot from the USB.

You can also upgrade to Ubuntu 20.10 from an earlier version.

Linux Mint is undoubtedly one of the best beginner-friendly and tough competitors of the most famous Ubuntu Linux. One of the reasons can be credited to its upstream codebase. Since Linux Mint is an Ubuntu-based distro, it uses the codebase of the latest Ubuntu long term support version.

Linux Mint 20

Linux Mint 20

After ending 2019 with the release of Linux Mint 19.3, the Linux Mint team is ready to roll out its first version with long-term support in 2020. As already revealed in their monthly blog, the upcoming Linux Mint 20 will be based on the next Ubuntu 20.4 LTS. So, in this article, I’m going to discuss everything about the new changes and release date of Mint 20.

 

Interesting Fact About Linux Mint Codename

Most of the Linux distros follow a particular pattern to give a codename for each version — for instance, Ubuntu uses a two-word adjective and animal name. Likewise, Linux Mint titles every release a female codename alphabetically. Therefore, starting with the Mint 1 “Ada” and the latest Mint 19.3 “Tricia,” and this is Linux Mint 20, codename Ulyana.

 

New features in Linux Mint 20 Cinnamon

Linux Mint 20 is a long-term support release which will be supported until 2025. It comes with updated software and brings refinements and many new features to make your desktop on a gaming desk be more comfortable experience.

 

Monitor frequency adjustment

Frequency modification of monitors is a long-sought demand by the Mint community. Consequently, Mint 20 now includes monitor frequency adjustment. This means you will be able to choose the frequency in the Cinnamon 4.6 display settings.

Linux-Mint-20-—-Monitor-display-setting

Fractional Scaling

Linux Mint 20 ships the Cinnamon 4.6 desktop environment that introduces fractional scaling. Hence, instead of either 100% (normal mode) or 200% (HiDPI mode) scaling for all monitors, you can now configure the scale value between 100% and 200% for each monitor independently. If you use high-resolution displays, it’ll be a big relief for you to have a better scaling option.

 

NVIDIA Optimus

Linux Mint 20 features improved support for NVIDIA Optimus.

The NVIDIA Prime applet now shows your GPU renderer and you can select which card to switch to straight from its menu.

nvidia

The NVIDIA “On-Demand” profile is also now fully supported. When you run in that mode, it is your Intel card which renders the session and a menu option is available to let you offload a particular application to your NVIDIA card.

nvidia-cinnamon

nvidia-cinnamon

Select an application in the menu, right-click and select “Run with NVIDIA GPU”. It’s that simple.

 

Mint-Y Theme

“Themes” applet is one of the unique features of Linux Mint that allows you to choose or install new themes and icons. In addition to that, Linux Mint 20 introduced two new colors, Pink and Aqua, in the default Mint-Y theme.

Furthermore, the Mint-Y theme now has a brighter color than before. Here’s a comparison of some of the old colors (on the left) with some of the new ones (on the right):

Linux-Mint-20-—-New-color-In-Mint-Y-theme

Linux-Mint-20-—-New-color-In-Mint-Y-theme

From the command-line, two new commands are available to offload to GLX or to Vulkan:

  • nvidia-optimus-offload-glx
  • nvidia-optimus-offload-vulkan

To boost compatibility and make it easier to boot Linux Mint 20 in live mode without NVIDIA drivers, “nomodeset” was also added to the “Compatibility Mode”.

 

Warpinator

The star of the show in Linux Mint 20 is a new application called Warpinator.

10 years ago, Linux Mint 6 featured a tool called “Giver” which could share files across the local network. Without any server or configuration, computers would automatically see each other’s and you could simply drag and drop files from one to another. When the Giver project was discontinued it had to be removed from Linux Mint and we’ve been missing that functionality ever since.

warpinator1

Warpinator is a reimplementation of Giver. Server configuration (FTP, NFS, Samba) is overkill for casual file transfers between two computers, and it’s a real pity to use external media (Internet services, USB sticks, external HDDs) just to share files when there’s a local network which could do just that.

With Warpinator, Linux Mint 20 brings back easy file sharing across the local network.

The main window shows you the computers on the local network which are also running Warpinator:

By clicking on a computer, you can see more information about it and exchange files with it:

No more USB sticks or external drive are needed just to send a file.

 

Other Enhancements In Linux Mint 20

  • Smooth Multi-monitor support
  • Use of middle-click button in Cinnamon’s keyboard applet
  • Better looking system tray
  • A new user interface for Gdebi tool

 

Linux Mint 20 Release Date And ISO Download

The Mint team has now officially released a new long-term Linux Mint 20 that will be supported until 2025. ISO images of any of the three Cinnamon, MATE, and Xfce edition are available to download from the official download page.

For further details, see Mint’s Snap documentation. You can read more on Mint’s arguments against Snap, and Ubuntu’s attempt to make peace with Mint and decide for yourself if you want to use Snap on Mint.

Of course, the usual selection of Linux desktop programs come ready to run. These include Firefox 77 for web browsing; LibreOffice 6.4.2 for your office needs; and Thunderbird 68.7 for email.

Overall, Mint remains a pleasure to use. I really wish Mint included Snap. Most desktop program developers agree that it, and its rival Flatpak, are the future for Linux desktop apps.

Looking ahead, Linux Mint 20 will receive security updates until 2025. Until 2022, future versions of Linux Mint will use the same package base. This means it will be trivial to upgrade to the next few versions.

If you’re new to Mint and want to give it a try, check out my How to install Linux Mint on your Windows PC article. It’s easy to do whether you want to wipe out Windows, run it with Windows, or just give it a trial run using a USB stick with persistent storage.

Beside all, get the Linux Mint 20 pre-installed and ready to run with eracks systems.

Ubuntu follows the release cycle of the new version twice a year, with one released in April and the other released in October, accompanied by many important improvements. The 2020 version will be Ubuntu 20.04 with the Focal Fossa identifier, which is expected to be released to global users starting April 23 next year.The codename of the official Ubuntu updates is chosen in alphabetical order, and is made up of 2 words, the first word is adjective and the second word will be noun, which is specific here as a certain animal is in danger of extinction, or sometimes mythical creatures such as Unicorns or Werewolfs (Wolves).

focalfossa

focalfossa

We have the Focala version of April 2020 with the word ‘Focal’ meaning ‘necessary’ and the Fossa is a carnivore that looks like a lynx, which can only be seen now. in Madagascar.

This is an interesting and unique code naming that only Ubuntu applies, giving users a sense of both curiosity and memorable.

However, the code names of Ubuntu releases sometimes reveal some of the characteristics of the releases. Ubuntu 20.04 will not only be an important release (with long term service), but also contain the strengths commonly found in Fossa species such as flexibility, agility and dominance.

In short, Ubuntu 20.04 is the LTS version, so the main focus of this release will be to bring stability and reliability to users. Focal Fossa came with lots of improvements, bug fixes, and especially new features. Let’s see some of them!

 

New Features in 20.04 LTS

 

Installer

The live server installer is now the preferred media to install Ubuntu Server on all architectures.

Besides architecture support, the main user visible new features are support for automated installs and being able to install the bootloader to multiple disks (for a more resilient system).

Installer

Installer

There have been many other fixes under the hood to make using encryption easier, better support installing to multipath disks, more reliable installation onto disks that have been used in various ways and allowing failures to be reported more usefully.

Linux Kernel

Ubuntu 20.04 LTS is based on the long-term supported Linux release series 5.4. Notable features and enhancements in 5.4 since 5.3 include:

  • Support for new hardware including Intel Comet Lake CPUs and initial Tiger Lake platforms, AMD Navi 12 and 14 GPUs, Arcturus and Renoir APUs along with Navi 12 + Arcturus power features.
  • Support has been added for the exFAT filesystem, virtio-fs for sharing filesystems with virtualized guests and fs-verity for detecting file modifications.
  • Built in support for the WireGuard VPN.
  • Enablement of lockdown in integrity mode.

Other notable kernel updates to 5.4 since version 4.15 released in 18.04 LTS includes support for AMD Rome CPUs, Radeon RX Vega M and Navi GPUs, Intel Cannon Lake platforms. support for raspberry pi (Pi 2B, Pi 3B, Pi 3A+, Pi 3B+, CM3, CM3+, Pi 4B), Significant power-saving improvements. Boot speed improvements through changing the default kernel compression algorithm to lz4 (in Ubuntu 19.10) on most architectures, and changing the default initramfs compression algorithm to lz4 on all architectures.

Toolchain Upgrades 🛠

Ubuntu 20.04 LTS comes with refreshed state-of-the-art toolchain including new upstream releases of glibc 2.31, ☕ OpenJDK 11, rustc 1.41, GCC 9.3, 🐍 Python 3.8.2, 💎 ruby 2.7.0, php 7.4, 🐪 perl 5.30, golang 1.13.

GNOME and visual improvements

Ubuntu 20.04 Focal Fossa comes with installed. It’s chock-full of visual improvements, resulting in better performance and a more aesthetically pleasing graphical experience. There’s also a new lock screen design and support for fractional scaling under X11.

GNOME 3.36

GNOME 3.36

A sleeker theme

GNOME’s new default theme is called “Yaru.” Even upon first loading into Focal Fossa, the desktop gives off a much more modern and sleeker vibe. This is mostly thanks to some color tweaks in the default theme and a darker wallpaper. The updated GNOME also allows you to choose between three different color themes: light, standard, or dark.

Network configuration

With this Ubuntu release, netplan.io has grown multiple new features as well, some of are as below:

  • Basic support for configuring SR-IOV network devices. Starting with netplan.io 0.99, users can declare Virtual Functions for every SR-IOV Physical Function, configure those as any other networking device and set hardware VLAN VF filtering on them.
  • Support for GSM modems via the NetworkManager backend via the modems section.
  • Adding WiFi flags for bssid/band/channel settings.
  • Adding ability to set ipv6-address-generation for the NetworkManager backend and emit-lldp for networkd.

ZFS support

Ubuntu introduced native support of ZFS in the 2019 interim release of Eoan Ermine. In Ubuntu 20.04 Focal Fossa, ZFS support has been further improved, though still flagged as being experimental. When installing Focal Fossa, you have the option to use ZFS if you click “advanced features” when asked about how you’d like to format your hard drive.

The newest version of Ubuntu features performance enhancements for ZFS and support for encryption. Ubuntu has a ZFS system tool called Zsys, which provides automated system and user state saving. It also integrates better with GRUB so a user can revert to an earlier system state before booting into the desktop.

Acceptance of ZFS in the enterprise world is still shaky, but it doesn’t seem to be going anywhere. Seeing support for it on a really popular distribution like Ubuntu is pretty neat.

 

Python3 by default

In 20.04 LTS, the python included in the base system is Python 3.8. Python 2.7 has been moved to universe and is not included by default in any new installs.

Remaining packages in Ubuntu which require Python 2.7 have been updated to use /usr/bin/python2 as their interpreter, and /usr/bin/python is not present by default on any new installs. On systems upgraded from previous releases, /usr/bin/python will continue to point to python2 for compatibility.

Snap Store

The Snap Store (snap-store) replaces ubuntu-software as the default tool for finding and installing packages and snaps.

QEMU

QEMU was updated to 4.2 release. There is so much that it is hard to select individual improvements to highlight, here just a few:

  • free page hinting through virtio-balloon to avoid migrating unused pages which can speed up migrations
  • PPC: NVIDIA V100 GPU/NVLink2 passthrough for spapr using VFIO PCI
  • Many speed improvements for LUKS backend
  • pmem/nvdimm support

For trimmed down container like isolation use-cases the new qemu has the microvm machine type which can be combined with the qboot ROM (available as bios-microvm.bin) to provide a reduced feature set at a much faster startup time. To further emphasize that you can use the package qemu-system-x86-microvm which provides an alternative QEMU binary stripped of all features not needed these use cases as sugegsted by the qboot ROM.

libvirt

libvirt was updated to version 6.0. See the upstream change log for details since version 5.6 that was in Ubuntu 19.04 or further back since verison 4.0 that was in Ubuntu 18.04.

Chrony

Chrony been updated to version 3.5 which provides plenty of improvements in accuracy and controls. Furthermore, it also adds additional isolation for non-x86 by enabling syscall filters on those architectures as well.

To further allow feeding Hardware time into Chrony the package GPSD is now also fully supported.

But still for simple time-sync needs the base system already comes with systemd-timesyncd. Chrony is only needed to act as a time server or if you want the advertised more accurate and efficient syncing.

Ubuntu 20.04 LTS “Focal Fossa”

Ubuntu 20.04 LTS “Focal Fossa”

There are a lot of other changes as well. To experience all the changes and improvements it is recommended to use and experiences this version of your own.

As of late April, Ubuntu 20.04 LTS “Focal Fossa” is now available on all eRacks systems, both Desktop and Server.

It should appear in the “Operating system” dropdown when you configure your system, and is the default on many / most of our systems.

If you don’t see it, or if you this it should be the default, (or shouldn’t!), please let us know – We are always listening for feedback!

Better Applications Search

Powered by the talent and the evident hard-work invested in this new release, it is amazing now that you can now search applications like lock screen, power off, log out and many more in a beautiful layout. It integrates well with screens that can be oriented vertically or horizontally which makes it sweet to interact with.

New design on the settings App

Renamed to settings, the GNOME Control Center now has an easy to use side bar which embraces the user with an intuitive and fluid navigation through the settings arena. Additionally, the About category now has a more information about your system, including which windowing system you are running (e.g. Wayland)

Supports The New Extensions App

You no longer need to utilize the GNOME Tweaks tool to separately install/manage extensions. Fedora 32 features the new extension app which lets you manage GNOME extensions directly.

fedora-extensions-app

fedora-extensions-app

However, you won’t find it pre-installed. You will have to look through the software center to get it installed or simply type in the following command:

sudo dnf install gnome-extensions-app

Revamped Settings Menu

As part of the new GNOME 3.36, you will find the Settings app to be re-organized and more useful than ever before. You can get more information about your system and access the options easily.

GNOME 3.36 also provides many additional features and enhancements. Check out the GNOME 3.36 Release Notes for further information

Improved Out of Memory handling

Previously, if a system encountered a low-memory situation, it may have encountered heavy swap usage (aka swap thrashing)– sometimes resulting in the Workstation UI slowing down, or becoming unresponsive for periods of time. Fedora 32 Workstation now ships and enables EarlyOOM by default. EarlyOOM enables users to more quickly recover and regain control over their system in low-memory situations with heavy swap usage.

For more details please visit the official Fedora Releases/32/ChangeSet.

 

To upgrade your existing Fedora 31 installation to Fedora 32, you need to run the following commands in terminal one by one:

sudo dnf upgrade --refresh

sudo dnf install dnf-plugin-system-upgrade

sudo dnf install dnf-plugin-system-upgrade

sudo dnf system-upgrade reboot

You can also perform a clean installation of the Fedora 32 by visiting its download page and download the ISO file. Or click the link below:

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 farther, 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.

 

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.

 

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.

Red Hat Enterprise Linux 8

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. 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

 

eRacks/INTELLINATOR22

Configure your Own eRacks/INTELLINATOR Server With Red Hat Enterprise Linux 8 (RHEL 8).

 

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.

  1. 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.
  2. 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.

fedora30Fedora 30 is now available on all eRacks systems.

Fedora is a community-driven Linux distro that’s sponsored by the open source giant Red Hat. As Fedora is the upstream source of the company’s commercial RHEL distro, it’s also used as a testing ground for RHEL. As Linux enthusiasts might already know, Fedora is known as an innovative Linux distro that doesn’t hesitate when it comes to testing new technologies and helping other distros by making changes upstream for all distros. Shipping with many useful open source software, it’s known for providing a GNOME-based fluid desktop experience.

 

 

 

Fedora community recently released Fedora 30 just after about the 6 months from the version release as Fedora 29. On Fedora magazine they wrote about the early release of Fedora 30.

It seems like it was just six months ago that we announced Fedora 29, and here we are again. Today, we announce our next operating system release. Even though it went so quickly, a lot has happened in the last half year, and you’ll see the results in Fedora 30.

Many desktop users love Red Hat’s community Linux Fedora. They have good reason. Fedora is a great Linux desktop. But Fedora’s far more than just a desktop. It comes in three major versions: One for the workstation, another for containers, and still another that works as a server both on your server hardware and on the cloud.

 

About many changes, “Matthew Miller”, the Fedora Project Leader, explained in a statement:

Computing scenarios don’t remain static and neither does Fedora. With the updates around Fedora 30, we’re providing an evolving spectrum of operating system editions to better meet diverse IT challenges. From containerized developer workspaces with Flatpak and Silverblue to expanded server and container infrastructure options in Fedora 30 Cloud and Fedora CoreOS, the Fedora Project remains focused on Linux innovation.

 

 

New features in Fedora 30

The biggest change in Fedora 30 is the new GNOME 3.32 desktop environment. Over the course of past few releases, GNOME desktop has made many changes to reduce its memory consumption; GNOME 3.32 takes things further and makes things more fluid and snappier by making enhancements in the core GNOME libraries.

On the visual front, the desktop environment adds a refreshed visual style that makes the overall look more polished. Moreover, the application icons, user icons, buttons, switches, etc., are also redesigned.

Talking about different packages that are included in the distro, you get the latest GCC 9, PHP 7.3, Bash 5.0, Ruby 2.6, and other apps.

This release is powered by the latest Linux 5.0, which brings better hardware support and display performance. You also get new features like support for energy-aware scheduling, Btrfs swap file, AMDGPU FreeSync, etc.

With the Fedora 30 release, the cloud and server releases are being combined into the Fedora Server Edition. Also, Fedora CoreOS is replacing Fedora Atomic Host as the container-focused offering. There are other variants as well, including Fedora Spins and Labs.

 

Fedora 30 Workstation

fedora_30_workstation

 

Fedora 30 Workstation includes the latest version of the GNOME interface, GNOME 3.32. Fedora also supports the other major Linux desktop environments, including Cinnamon, KDE, LXDE, MATE, and Xfce. It also includes fractional scaling, a refreshed visual style, animation improvements, and new icons. The net effect is to make a more visually pleasing desktop, which works well on high-end monitors.

Fedora Workstation now uses the “flicker-free boot” system, so the display does not turn on and off during the boot process.

You can also now run the Fedora desktop as a containerized desktop, Fedora Silverblue, with rpm-ostree at its heart. This replaces the traditional RPM package management with atomic upgrade/rollback. In this model, Fedora provides ready-made base operating system image. When you install a program, using either rpm-ostree or Flatpak, it creates essentially a restore point. These are then tracked, and if something goes wrong, you can reset to your restore point with minimal harm done.

 

Fedora 30 Server

fedora_30_server

 

Fedora 30, released April 30, 2019, has the following new and improved features:

The product definitions for Fedora’s “Editions” have been revamped. Fedora Cloud and Fedora Server editions are now a single product, simply called Fedora Server. Fedora Atomic Host has been replaced with Fedora CoreOS, in the wake of Red Hat’s acquisition of that container-based Linux distribution. Fedora Workstation remains mostly the same.

Fedora Server now supports Linux System Roles, created by Ansible to provide consistent ways to configure common Linux subsystems such as the network, the email system (Postfix), SELinux, and a few others. The list of roles is constantly being expanded.

Almost all Python 2 packages have been removed from the system, as part of Fedora’s switch from Python 2 to Python 3.

MongoDB has been removed from Fedora, as its licensing (the Server-Side Public License v1) is not believed to be compatible with other free software licenses.

Support for many deprecated cryptography standards is being removed: DES, 3DES, CRC32, and MD4. RC4 and MD5 are being marked as deprecated.

As with each edition of Fedora, many individual software components have been upgraded:

  • Bash 5.0
  • Boost 1.69
  • Erlang 21
  • FreeIPA 4.8 (which now uses Python 3.6)
  • GCC 9
  • glibc 2.29
  • Golang 1.12
  • GNOME 3.32
  • Haskell GHC 8.4
  • java-openjdk JDK12
  • PHP 7.3
  • Ruby 2.6
  • Vagrant 2.2

For more details please visit the official Fedora Releases/30/ChangeSet.

 

To upgrade your existing Fedora 29 installation to Fedora 30, you need to run the following commands in terminal one by one:

sudo dnf upgrade --refresh

sudo dnf install dnf-plugin-system-upgrade

sudo dnf install dnf-plugin-system-upgrade

sudo dnf system-upgrade reboot

You can also perform a clean installation of the Fedora 30 by visiting its download page and download the ISO file. Or click the link below:

Ubuntu 19.04, aka “Disco Dingo“, is now available on all eRacks systems.

Ubuntu 19.04 (Disco Dingo)

Canonical – The company behind Ubuntu published its regular (non-LTS) version as Ubuntu 19.04 (Disco Dingo) on April 18, 2019. The first Ubuntu 19.04 beta released on March 28. Other milestones during “Disco Dingo” development included feature freeze on February 21, 2019, UI freeze on March 14, 2019, and kernel freeze on April 1, 2019.

Up until this version, the codename of each Ubuntu release is traditionally made up of an adjective and an animal, both beginning with the same letter. But that’s only partly true this time – The word “Disco is actually both a noun and a verb rather than adjective. A disco is a type of club or party at which people dance to music, often under lights.

A “Dingo” is a type of feral dog native to Australia and known for its sand-colored coat. Dingo dogs hunt alone or in cooperative packs. Inspired by the nature of the Dingo (which often sulks off when humans are around) the word has become informal Australian slang meaning ‘cowardly’, e.g., ‘he dingoes his way out of the date’.

Ubuntu 19.04 Disco Dingo is only the second Ubuntu release to use the letter ‘D’, following Ubuntu 6.06 “Dapper Drake” (released back in the land before time, aka 2006).

Since Ubuntu 19.04 (Disco Dingo) is a non-LTS version (not a Long Term Support version), it will be supported for 9 months until January 2020. If you need Long Term Support, it is recommended you use Ubuntu 18.04 LTS instead.

This article for Ubuntu 19.04 (Disco Dingo) provides an overview of the release and documents the known issues with Ubuntu 19.04 and its flavors.

Since the release of Ubuntu 19.04, everyone is talking about its Desktop Version. We’re going to do something a little different. We’re going to start with the Ubuntu 19.04 Server version first. Let’s what’s new:

Ubuntu 19.04 (Disco Dingo) Server Updates.

Every time Canonical releases a new version, it brings many new and noticeable changes. Each new version improves the previous one and strives to provide better user experiences.

Canonical made many changes on Ubuntu 19.04 (Disco Dingo) Server – the following are notable:

QEMU

In Ubuntu 19.04, QEMU was updated to the 3.1 release.

Migrations from former versions are supported just as usual. When upgrading it is always recommended to upgrade the machine types allowing guests to fully benefit from all the improvements and fixes of the most recent version.

Qemu now has virglrenderer enabled which allows to create a virtual 3D GPU inside qemu virtual machines. That is inferior to GPU pass-through, but can be handy if the platform used lacks the capability for classic PCI pass through as well as more modern mediated devices.

For more details, see the QEMU 3.1 change log.

LIBVIRT

Among many other changes worth to mention is the ability to have GL enabled graphics as well as mediated devices to be configured while still being guarded by custom apparmor profiles generated per guest. This is required for the use of GPU based mediated devices as well as VirGL (mentioned above in the QEMU section). For bringing these changes libvirt was updated to version 5.0.

DPDK

Ubuntu includes 18.11.x the latest stable release branch of DPDK. The very latest (non-stable) version being 19.02 was not chosen for downstream projects of DPDK (like Open vSwitch) not being compatible.

DPDK dependencies were reorganized into more or less common/tested components. Due to that most DPDK installations will now have a smaller installation footprint and less potentially active code to care about.

For more details see the release notes.

SAMBA

Samba was updated to version 4.10.x, and one of the big changes here is python3 support. In Disco, samba and its dependencies are all python3 only now, with the exception of tdb. tdb still builds a python2 package, namely python-tdb, but all the others, including samba itself, are python3 only.

Open-VM-Tools

To run well integrated as VMware guest Ubuntu 19.04 comes with the latest open-vm-tools version 10.3.10. Details about the changes can be found in the upstream changelog

Raspberry Pi

Ubuntu 19.04 comes with an easy way of enabling Bluetooth support on the raspi3 Ubuntu-server preinstalled images. Install the Pi-Bluetooth package (now available in multiverse) with ‘sudo apt install pi-bluetooth’.

Please note that supported Pi devices which have Bluetooth (at the time of writing, the Raspberry Pi 3B, 3B+, and 3A+) can have either serial console or Bluetooth support enabled at any given time (not both). With the Pi-Bluetooth package installed, edit it at ‘/boot/firmware/config.txt’ and set ‘enable_uart=1’ to enable serial console, or ‘enable_uart=0’ to enable Bluetooth. The change will take effect after the next reboot.

Open vSwitch

Open vSwitch has been updated to 2.11. This updated Open vSwitch version has support for the kernel versions 4.16.x and 4.17.x. Also the following features can be found on this version.

  • “mod-table” command can now change OpenFlow table names.
  • The environment variable OVS_SYSLOG_METHOD, if set, is now used as the default syslog method.
  • The environment variable OVS_CTL_TIMEOUT, if set, is now used as the default timeout for control utilities.
  • OVN-SB schema changed: duplicated IP with same Encapsulation type is not allowed any more. Please refer to Documentation/intro/install/ovn-upgrades.rst for the instructions in case there are problems encountered when upgrading from an earlier version.
  • New support for IPSEC encrypted tunnels between hypervisors.
  • ovn-ctl: allow passing user:group ids to the OVN daemons.
  • IPAM/MACAM add the capability to dynamically assign just L2 addresses
  • IPAM/MACAM add the capability to specify a static ip address and get the L2 one and it is allocated dynamically using the following syntax: ‘ovn-nbctl lsp-set-addresses <port> “dynamic <IP>”.’

Please read the Open vSwitch release notes for more detail.

OpenStack Stein

Ubuntu 19.04 includes the latest OpenStack release, Stein, including the following components:

  • OpenStack Identity – Keystone.
  • OpenStack Imaging – Glance.
  • OpenStack Block Storage – Cinder.
  • OpenStack Compute – Nova.
  • OpenStack Networking – Neutron.
  • OpenStack Telemetry – Ceilometer, Aodh, Gnocchi, and Panko.
  • OpenStack Orchestration – Heat.
  • OpenStack Dashboard – Horizon.
  • OpenStack Object Storage – Swift.
  • OpenStack Database as a Service – Trove.
  • OpenStack DNS as a Service – Designate.
  • OpenStack Bare-metal – Ironic.
  • OpenStack Filesystem – Manila.
  • OpenStack Key Manager – Barbican.

Please refer to the OpenStack Stein release notes for full details of this release of OpenStack.

WARNING: Upgrading an OpenStack deployment is a non-trivial process and care should be taken to plan and test upgrade procedures which will be specific to each OpenStack deployment. For Upgrading successfully please make sure you read the OpenStack Charm Release Notes for how to deploy Ubuntu OpenStack using Juju. Or simply contact eRacks Systemsexperts for help.

There are many other changes on newly released Ubuntu 19.04 non-LTS Server. Please read the Ubuntu 19.04 (Disco Dingo) non-LTS Server release note for more details.

 

 

 

Ubuntu 19.04 (Disco Dingo) Desktop (And Kernel) updates.

Linux Kernel 5.0.0-8 “Shy Crocodile”

The Linux Kernel had its number bumped to 5.0.0-8 by Linus Torvalds, but not because of particularly noteworthy code changes. Usually, a significant number jump like this would echo an equally significant code or functionality change, but that isn’t the case. In an email to the Linux Kernel Mailing List, he explained:

The numbering change is not indicative of anything special. If you want to have an official reason, it’s that I ran out of fingers and toes to count on, so 4.21 became 5.0.

Torvalds went on to give a breakdown of the code changes in Linux 5.0:

This new kernel should be faster, too, as work was done to speed up the anti-Spectre and Meltdown code.

GNOME desktop 3.32

Ubuntu 19.04 ships with the latest GNOME desktop 3.32. This brings performance improvements, a host of bug fixes and some important new features. Beyond the visual changes, GNOME itself is faster and uses fewer GPU resources thanks to work done by both Canonical and the upstream GNOME team.

Of course, there’s a new wallpaper in latest GNOME desktop 3.32. But the first thing you’ll probably notice is a new icon on the desktop for your home directory. If you don’t like it, you can install GNOME Tweaks and use it to hide the home directory icon.

In keeping with modern “flat” design, the desktop’s top bar and launcher have solid-black backgrounds. The application menus have been moved back to each application’s window. They no longer appear in the toolbar. That’s a change in GNOME and not a design decision from Canonical. Some applications always kept their menus in their own application windows, which made the experience inconsistent. There were also some long-standing issues that were tough to fix. Now, that whole initiative has been canned in favor of a traditional menu placement—each applications menu is in the application’s own window.

Fractional Display Scaling (Possibly)

GNOME 3.32 includes support for fractional scaling, which is of interest to people with high DPI (Dots Per Inch) displays.

Unfortunately, in the modified version of GNOME supplied with Ubuntu, the fractional scaling settings are either hidden or not accessible to us. Eventually, a tool might allow access to these settings—or another means of accessing those settings will emerge from the user community. After all, they’re in GNOME.

Live patch for Reboot-Free Kernel Updates

Canonical introduced Live patch in Ubuntu 18.04 LTS, only to remove it again in 18.10. It’s now back, complete with this new tab in Software & Updates.

Livepatch

 

Ubuntu 19.04’s Software and Updates app has a new tab called Live-patch. This new feature is intended to allow critical kernel patches to be applied without rebooting. For people using Ubuntu at home, on machines that get powered off frequently, requiring a power cycle to install a kernel update isn’t a hardship. If your Ubuntu computer is providing an external service or is hosting a website, it becomes trickier to try to schedule in the reboots.

New Icons and Visual Tweaks

The Yaru icon set has had a refresh, and new icons have been added to cater for more third-party applications. This icon set looks more coherent and slick. There’s evidence of attention being paid to the user interface all over. Files has had a facelift, and it looks crisp and feels responsive. That’s not a surprise.

Icons

 

Even the Terminal window has been polished up. The GNOME Terminal application has a new title bar with a prominent “New Tab” button and search icon.

The System menu has a new cogwheel Settings icon that replaces the old “crossed wrench and screwdriver” icon.

Application Permission Controls

GNOME’s Settings app now lets you control various application permissions. You can even choose whether or not each application can show notifications.

Application

 

Night Light Improvements

The Night Light feature changes the hue of your computer’s display, reducing the amount of blue in the display illumination as the sun sets. You can now configure the schedule for the Night Light yourself. You can also select the color temperature—or “warmth”—of the display when Night Light is activated.

Light

 

Updated Sound Controls

The Sound controls have been revamped. You don’t get more functionality than before, but the controls are laid out more conveniently and logically.

Sound

 

Raspberry Pi Touch Support

The bulk of the driver work in the kernel has been to graphics drivers, with enhanced support for displays ranging in size and capability—from the AMD FreeSync NVIDIA RTX Turing to the Raspberry Pi Touch Display. The Debian-derived Raspbian Linux already supported the Raspberry Pi Touch Display, but now you have the choice of using native Ubuntu with your Pi Touch.

There are many other changes as well. Some of them are mentioned below:

  • Tracker is now included by default. This allows the desktop to keep track of recently used files and improves searching.
  • Right click handling is now “area” by default. This allows both two-finger right clicking and clicking in the bottom right corner of the touchpad
  • alt-tab handling now switches windows by default. Switching applications by default can be done with super-tab
  • Preview order of windows in the dock is now static and based on the order in which the windows were added
  • IWD can now be enabled for use with Network Manager. IWD is a new alternative to wpa supplicant and is in testing for consideration in the future.
  • Installing Ubuntu Desktop on vmware will now automatically install the open-vm-tools package to improve integration.
  • The Yaru theme has seen further refinement and updates and includes a new icon theme.
  • Safe Graphics Mode. A new option is added to the Grub menu which will boot with “NOMODESET” on. This may help you resolve issues on certain graphics cards and allow you to boot and install any propriatary drivers needed by your system.
  • The latest releases of Firefox (66.0) and LibreOffice (6.2.2) are available and installed by default.

 

 

Some of the Common New features and Updated Packages in both Ubuntu 19.04 (Disco Dingo) non-LTS Desktop and Server Version.

Ubuntu 18.10, aka ‘Cosmic Cuttlefish’, is available now on all eRacks systems.

 

cosmic_cuttlefish

 

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?”

Linux Kernel

 

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.

 

GNOME 3.30

 

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.

Microsoft Reaper

Shortly after the first news appeared, that Microsoft was in the process of buying Github, a new Github repo appeared –

The Github Evacuation Center.

This repo quickly soared to the #1 spot in the “Trending” area on Github, and as this was politically inconvenient, it was removed by Github without notice or reason given.

Sadly, I expect this to be the future of Github, now, no more transparent bastion of Open Source and code.

Wired Magazine has an article saying as much, and laments that it’s inevitable that Github will be come more restrictive, take down controversial repos, and stop hosting projects which are not in Microsoft’s interest.

When I saw the photo at the right, my first reaction, was “Yes! But why only Skype and Mojang?!” – So, this prompted me to write, on the spur of the moment, the following letter as a comment on the Github issue:


The row of doors isn’t nearly long enough. This has been going on for 4 decades.

A few notable examples from memory, without having to research or refer to the many books about Microsoft and/or Bill Gates:

From the eighties:

Quarterdeck systems – QEMM – (Quarterdeck Extended Memory Manager) a utility which made better / efficient use of DOS “High” memory above 640K. Microsoft cloned a vastly inferior version of the product, and bundled it for free with a newer version of DOS, thus killing the market for the product.

From the nineties:

Digital Research – DR Dos – a superior DOS clone. Microsoft introduced a vaguely-worded dialog box, in it’s apps (eg, early MS Word [UPDATE: Windows 3.1]) which it displayed when it figured out it was running on top of DR dos, which used simple FUD (without any actual faults) to scare people away from DR DOS.

The code to detect DR DOS, was encrypted and hidden, and was obviously written to do nothing but target a competitor – this was discovered and dubbed the infamous AARD code, written about by Andrew Shulman and covered in countless publications including Dr Dobbs, etc

Yet no DOJ inquiry or any other action was taken, despite obviously breaking several laws against anticompetitive behavior, and then hiding it (shows intent).

From the 90s / 2000s:

Novell, Word Perfect (Maybe MS was just after Provo, UTAH? JK) – Both these stories are more well known –

WordPerfect was the only real competitor to the mediocre-at-best MS line of productivity apps (no incentive not to be mediocre, that way they can sell you a new copy every year or two of the product you already bought, and call it an “Upgrade”) – and MS killed the superior WordPerfect Write and Quattro Spreadsheet products with a weak “Look-and-feel” lawsuit – which they LOST, but not until the parent company was destroyed and unable to recover.

Novell is a more involved story, but suffice it to say that they again, like QEMM, built a successful product on DOS’s shortcomings – which then simply acted like product feature vetting for MS, so they could build / buy or copy the solutions that Novell introduced, thus rendering Novell redundant (in the British sense).

From the 2000s / 2010s:

Borland – Despite a vastly superior suite of developer products, MS poached it’s head developer and architect, Anders Heijlsberg, to be their head architect for .NET. His first task was to specifically copy several key innovations from Borland, which supposedly (according to MS) didn’t violate any copyright or IP agreements from the departing Borland – although this was controversial, again, lawsuits or the threat thereof were used effectively by MS to prevail.

This Rant / Diatribe

Sorry, I got carried away – 🙂

This was written on impulse, as a reaction to the door photo, completely off the top of my head in about 20 minutes, without so much as a quick Google to check dates, so forgive me if the above has minor issues to correct – I will update if I need to make corrections, but I do know from memory, that it’s essentially correct.

I remember these events over 3-4 decades, because of the MS’s consistently appalling and astounding behavior, that has continued unchecked, and remains to this day still unpunished and unaddressed, despite a slap on the wrist from our country’s DOJ, and from Europe, who’s various efforts to stop MS’s anticompetitive behavior were ineffective at best, and simply encouraged them to play brinkmanship at worst and improve their knowledge of the line, so they could push it.

I write this because MS’s behavior, as I slowly learned by experience of living though the above events, and the light slowly dawning on me that this was a pattern, and not just one or two coincidental events, is what motivated me to start my company, and try and have a higher bar for ethics and how to treat one’s competitors – and to encourage, foster, and sponsor more egalitarian software products and superior technical solutions in the process.

Feel free to republish this, along with the reaper image (it doesn’t make sense without it), wherever you see fit.

We have our code on Github too. We’re looking for where we’re going to move.

Maybe we’ll self-host, or use our colo and hosting resources to host a new Git-like startup for Open Source?

Update 6/7/18: corrected software that raised DR DOS dialog box (Windows 3.1), added references to AARD and FUD.
