Ubuntu 17.10 Artful Aardvark!

    Ubuntu 17.10, code named Artful Aardvark; I guess you already know that Artful means full of art or skill. And Aardvark is a medium-sized, burrowing, nocturnal mammal native to Africa. Colloquially, it is called African Ant Eater.

Nowadays Ubuntu become the world’s most popular desktop Linux operating system, and with its latest short-term support release, it’s clear Canonical want to keep a firm grip on the title.

Artful Aardvark

‘Artful Aardvark’ (Ubuntu 17.10)

As release with Artful Aardvark (Ubuntu 17.10) in October 19, 2017 Canonical continues Ubuntu’s proud tradition of integrating the latest and greatest open source technology into a high-quality, easy-to-use Linux distribution. Ubuntu 17.10 Artful Aardvark marks an all-new chapter in Ubuntu’s already rich history. As always, the team has been hard at work through this cycle, introducing new features and fixing bugs.

Ubuntu 17.10 Debuts with An All-New Desktop

This is the first version of Ubuntu to use GNOME Shell as the default desktop. ‘The HUD, global menu, and other Unity features are no longer included’. By choosing to drop Unity most of Ubuntu’s home-grown usability efforts also fall by the wayside.

Ubuntu 17.10 Desktop

Ubuntu 17.10 Desktop

In Unity’s place comes a bespoke version of GNOME Shell that is ‘customized’ to resemble something that’s superficially close to the Unity desktop layout. The Ubuntu 17.10 desktop uses a two-panel layout: a full-height vertical dock sits on the left-hand side of the screen, while a ‘top bar’ is stripped across the top.

The top bar plays host a new type of app menu, a calendar applet/message tray, app indicators, and a unified status menu for managing network, volume, Bluetooth and user sessions.

Ubuntu Dock

The new Ubuntu Dock is both a task manager and an application launcher. It shows icons for open and running software windows as well as ‘pinned’ launchers for user’s favorite apps.

Ubuntu Dock

Ubuntu Dock

The dock is also global; it displays icons/applications from all workspaces regardless of which one user is actually viewing.

Both the Ubuntu Dock and the top bar are semi-transparent, which adds nice visual presence. When a window touches either element the “dynamic transparency” feature kicks in to render both dock and top bar darker, making panel label contents more legible in the foreground.

Activities & Workspaces

The main “desktop” area remains a usable space on which user can place icons, folders and files.

Though there’s no longer a true global app menu, but the majority of apps place a small menu in the top bar bearing the name of the app in focus. These app menus contain a solitary ‘quit’ button at the least, or a full complement of options at most.

Workspaces

Activities & Workspaces

Workspaces are a common feature found on most modern desktop operating systems including Windows 10, so it’s a good thing that Ubuntu hasn’t ditched them. User can easily move windows between workspaces by clicking on a window and moving it on over the workspace.

Applications Overview

In Ubuntu 17.10 Applications are listed alphabetically, ordered into scrollable pages. User can launch an application by clicking on it, selecting it with keyboard arrow keys and pressing enter, or by touching it.

Applications Overview

Applications Overview

After years of ‘footnote’ releases that brought only minor tweaks, the ‘Artful Aardvark’ brings all-out with change, ready to usher in the new era. Under the hood, there have been updates to many core packages, including a new 4.13-based kernel, glibc 2.26, gcc 7.2, and much more in Ubuntu Desktop. Let’s have a brief list view on some of those updates.

  • On supported systems, Wayland is now the default display server. The older display server is still available: just choose Ubuntu on Xorg from the cog on the log in screen.
  • GDM has replaced LightDM as the default display manager. The login screen now uses virtual terminal 1 instead of virtual terminal 7.
  • Printer configuration is now done in the Settings app: Choose Devices and then Printers. The tool uses the same algorithms for identifying printers and choosing drivers as the formerly used system-config-printer, and makes full use of driverless printing to support as many printers as possible.
  • The default on screen keyboard is GNOME’s Caribou instead of Onboard.
  • Calendar now supports recurring events.
  • LibreOffice has been updated to 5.4.
  • Python 2 is no longer installed by default. Python 3 has been updated to 3.6.
  • The ‘Rhythm box’ music player now uses the alternate user interface created by Ubuntu Budgie developer David Mohamed.
  • The Ubuntu GNOME flavor has been discontinued. If a user is using Ubuntu GNOME, he will be upgraded to Ubuntu.

Note: Install gnome-session and choose GNOME from the cog on the login screen if user would like to try a more upstream version of GNOME. If any user’ d like to also install more core apps, he’d install the vanilla-gnome-desktop met package.

 

    Not only the Ubuntu 17.10 Desktop but also, there are significant changes into the Ubuntu 17.10 Server version too. For the Ubuntu Server 17.10, the OS Version for the printing server has been increased to announce Windows Server 2003 R2 SP2 ID mapping checks added to the testparm(1) tool. There are some ID mapping backends too, which are not allowed to be used for the default backend. Winbind will no longer start if an invalid backend is configured as the default backend. The others are as follows,

Ubuntu 17.10 Server

Ubuntu 17.10 Server

Qemu 2.10

Qemu has been updated to the 2.10 release. Since the last version was 2.8.

Among many other changes there is one that might need follow on activity by the user/admin: Image locking is added and enabled by default. This generally makes execution much safer, but can break some old use cases that now explicitly have to opt-in to ignore/share the locks by tools and subcommands using the –force-share option or the share-rw dqev property.

Libvirt 3.6

Libvirt has been updated to version 3.6.

LXD 2.18

LXD was updated to version 2.18. Some of the top new features of LXD 2.18 are:

  • Native Ceph RBD support.
  • Support for cloud instance types.
  • Pre-seeding of the “lxd init” questions through yaml.
  • New client library.
  • Improved storage handling (volume resize, auto re-mapping on attach, …).
  • A lot of small improvements to the client tool.

DPDK 17.05.2

Ubuntu 17.10 includes the latest release of DPDK that has stable updates: 17.05.2. This made it possible to integrate Open vSwitch 2.8.

Open vSwitch 2.8

Open vSwitch has been updated to 2.8. Though user need to specify dpdk devices via dpdk-devargs.

New BIND9 KSK

The DNS server BIND9 was updated to include the new Key Signing Key (KSK) that was published on July 11, 2017. Starting on October 11, 2017, that key will sign the root zone key, which in turn is used to sign the actual root zones.

Cloud-Init

The cloud-init version was updated to 17.1. Notable new features for cloud-init are as follows,

  • Python 3.6 support.
  • Ec2 support for IPv6 instance configuration.
  • Expedited boot time through cloud-id optimization.
  • Support for netplan yaml in cloud-init.
  • Add cloud-init subcommands collect-logs, analyze and schema for developers.
  • Apport integration from cloud-init via ‘ubuntu-bug cloud-init’.
  • Significant unit test and integration test coverage improvements.

Curtin

The Curtin version is updated to ‘0.1.0~bzr519-0ubuntu1’. New features are:

  • Network configuration passthrough for ubuntu and centos.
  • More resilient UEFI/grub interaction.
  • Better support for mdadm arrays.
  • Ubuntu Core 16 Support.
  • Improved bcache support.

Samba

Samba is updated to version 4.6.7. Important changes in the 4.6.x series are:

  • Multi-process Net logon support.
  • New options for controlling TCP ports used for RPC services.
  • AD LDAP and replication performance improvements.
  • DNS improvements.

    There are many other changes too. We recommend that all users read the release notes, which document caveats, workarounds for known issues, as well as more in-depth Release Notes.

    Users of Ubuntu 17.04 will be offered an automatic upgrade to 17.10. As always, upgrades to the latest version of Ubuntu are entirely free of charge.

Remember, here at eRacks, we offer pre-installed Ubuntu 17.10 Artful Aardvark with our new systems either directly from the OS dropdown, or by custom quote.

Yakkety Yak!

When a person who smokes decides to quit, it is called smoking cessation. Often, this decision is associated with a desire to lead a healthier life by eliminating the risks that are associated with smoking. Freeing oneself from the habit of smoking, however, is not an easy task, as tobacco products contain the addictive chemical known as nicotine. Because of its addictive nature and problems that are associated with nicotine withdrawal, there is a significant risk of relapse. But the vast majority of smokers want to quit, and up to half make the attempt to do so every year. For more information about healthy supplements visit riverfronttimes.com.

Smoking Cessation Methods

Fortunately, there are a variety of ways for smokers to quit, although no one method is universally successful. The most common method falls under the umbrella of do-it-yourself smoking cessation. One of the most common and well-known examples of unassisted cessation is an immediate and abrupt attempt to stop smoking altogether. This method is popularly known as the “cold turkey” approach, and it does not include the use of any therapy or medication. Another example of a self-help tactic is to taper off, or gradually reduce one’s habits until they can abandon tobacco smoking entirely. Typically, this technique also involves setting a date for when tobacco smoking will cease completely. Check out these nutrisystem reviews.

Doctors from This Site ensure that Smokers may also resort to methods that involve nicotine replacement products such as nicotine gum, which provides the body with nicotine in order to deter the user from smoking to satisfy their craving. There are also nicotine patches and inhalers that deliver a dose of the drug to reduce the impact of withdrawal symptoms. Nicotine replacement products contain less nicotine than cigarettes and enable the person to gradually reduce their intake of the drug until they no longer need any at all. In addition, they do not contain all of the harmful chemicals in cigarettes, such as arsenic, tar, carbon monoxide, or formaldehyde.

Another means of quitting smoking involves seeking assistance to quit one’s tobacco habit. Community help is available in many forms, including local support groups, treatment centers, and turning to doctors for prescription medication. Prescription medication used to help tobacco smokers quit includes bupropion or varenicline, marketed as Zyban or Chantix, respectively. Family and friends are also reliable resources when it comes to quitting smoking. The Internet also offers support groups that smokers may turn to for help. More uncommon methods for trying to quit include acupuncture, aromatherapy, hypnosis, and herbal remedies.

Immediate Health Benefits of Quitting

There are significant benefits that tobacco smokers can appreciate right away when they decide to stop smoking, some of which begin just 20 minutes after the last cigarette. For example, the body’s blood pressure and pulse rate will begin to decline toward normal levels. Within a day, oxygen levels will increase, while the amount of nicotine and carbon monoxide within the body will start to subside, along with the odds of a heart attack. After two days without smoking tobacco, a person will notice that their sense of smell and taste have improved. The lungs will also start to improve in function after two to 12 weeks, as will blood circulation. Another immediate and important benefit of quitting smoking is the financial benefit. Smoking is a very expensive habit, and thus, quitting smoking will immediately add money to a person’s budget.

Long-Term Benefits of Quitting

Over the long term, ex-smokers will enjoy more physical energy to exercise and do general tasks like walking up stairs. Sexual function will improve due to the improvements in blood flow throughout the body. It will also improve a woman’s ability to get pregnant and eliminate smoking-related damage to a man’s sperm. The improvement in oxygen flow in an ex-smoker’s body will result in slowing the aging of the skin and delaying the onset of wrinkles. Quitting smoking will also reduce the risk of damage to the eyes, such as cataracts. The most important benefits of quitting smoking are the reduction in the odds of heart attack, stroke, and various cancers, and as a result, quitting can add years to one’s life.

Mint 18 is here!

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

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

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

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

How to Buy a Luxury Watch: A Complete Guide

Buying a luxury watch is an exciting endeavor. Not only are luxury watches a quintessential status symbol, but they are also fascinating little machines. They can function in extreme environments, looking amazing while they do it. This is the most affordable and popular rolex super clone.

We want this momentous occasion to be pleasant. So we put together an easy, step-by-step guide to buying an amazing luxury watch. Let’s get started.

men's luxury watches

Selecting Watch Movements

Before you step foot into a boutique, you’ll want to know the basics of what you’re after in a watch. The movements, also known as “caliber” is what makes your watch work.

The 3 most popular types of watch movements are mechanical, automatic, and quartz.

Automatic

An automatic watch is similar to a mechanical watch except you don’t have to wind it yourself. The watch has even higher intricacies within it which wind the watch for you.

Most luxury watches on the market use automatic movements to keep themselves ticking. For example, this fashionable Rolex Submariner 16613 Oyster Perpetual powers itself.

Mechanical

A mechanical watch is the type you manually wind by hand. This is the oldest way of giving energy to a watch, used for centuries.

No routine battery changes is a plus of these watches. However, these mechanical watches need a tune-up every few years to keep the parts moving properly. Many vintage watches use this type of movement.
