Ubuntu 17.04 Zesty Zapus!

    Ubuntu 17.04, code named Zesty Zapus; Zesty, is an adjective for ‘great enthusiasm and energy’, while Zapus, is the genus name of a North-American mouse that is said to be the only mammal on Earth that has up to 18 teeth in total.

     Ubuntu 17.04 or Zesty Zapus final release is available from April 13, 2017 and let’s see what’s new in Zesty Zapus!

Updated Kernel

Ubuntu 17.04 Alpha 2 was released on the 26th of January and all the opt-in flavors are powered by an updated kernel, version 4.9.5.

The final Zesty Zapus includes the Linux kernel 4.10, which is known to enhance the performance of Intel Kaby Lake and AMD Ryzen systems.

Driverless Printing

We all know that printers are not that friendly with Linux. Vivaldi Snapshot 1.3.537.5 Brings Improved Proprietary Media Support on Zesty Zapus.

Ubuntu 17.04 is bringing the support for IPP Everywhere. It’s a new protocol that allows personal computers and mobile devices to find and print to networked and USB printers without using vendor-specific software.

Most of the printers sold these days already support IPP protocol. This means that you don’t need to install drivers for printer from XYZ manufacturer. You can search for it on the network and use it for printing.

Unity 8

Ubuntu users have been hearing a lot about Unity 8 for the last couple of years but so far Unity 8 is nowhere to be seen officially. Of course, there are ways you can run Unity 8 in Ubuntu releases already but the fact is that you should use them only if you are Linux-savvy.

Zesty Zapus does bring this experimental build of Unity 8. Though Unity 7 will still be the default desktop environment, you can select between Unity 7 and Unity 8 at the login screen.

Note: Unity 8 won’t be the default desktop on Ubuntu 17.04 or 17.10 or 18.04. Ubuntu Unity is dead and GNOME will be the default desktop environment starting Ubuntu 18.04.

 

Swap File Instead of Swap Partition

Canonical’s Dimitri John Ledkov announced that Ubuntu 17.04 will use Swap files by default on non-LVM installs.

He explains that, quite simply, the need for a separate swap partition that’s (at least) twice the RAM size “makes little sense” on systems where memory isn’t limited.

For a common, general, machine most of the time this swap will not be used at all. Or if said swap space is in use but is of inappropriate size, changing it in-place in retrospect is painful.

Ubuntu17.04 Zesty Zapus will use swap files by default. Sizing of swap files is different to the swap partitions and typically use no more than 5% of free disk space (or 2048MB of RAM), which is another potential benefit.

The change does not apply to those who install Ubuntu using the LVM (Logical Volume Manager) option.

What’s important here is that some form of swap is maintained, it doesn’t matter how the swap is implemented. Anyone who’s ever used or set-up a ‘no swap’ system only to then run out of memory will know it’s not a pretty experience!

More Snaps

Canonical’s Will Cooke said that “by 18.04 everything will be Snaps and Unity 8 all the way down” and Engineering director Kevin Gunn, added that, “Canonical has an aggressive internal goal to try to get a usable all-snaps based image for Unity 8 out by 17.04”. So, although Snaps wouldn’t be replacing apt anytime soon.

32-bit PowerPC Support is Dropped

You might not have realized but Ubuntu till now used to support the aging 32-bit PowerPC architecture. As Debian has decided to drop this support, naturally Ubuntu followed the suit and has decided to drop the support for 32-bit PowerPC too, starting from Ubuntu 17.04.

     As you may have already noticed that most of these updates discussed above are found in Desktop version. So, in general, a common question automatically comes up, ‘isn’t there any changes for the new Ubuntu 17.04 server version?’ Well, of course Ubuntu released many updates for the Ubuntu 17.04 server version as well. Ubuntu Server 17.04 also comes with these following updates,

Qemu 2.8

Qemu has been updated to the 2.8 release.

Libvirt 2.5

Libvirt has been updated to version 2.5. For administrators worth to consider is that depending on the system setup and huge page size availability the specification of a page size for huge pages in a guest xml can now be mandatory.

LXD 2.12

LXD, now at version 2.12, introduces support for GPU passthrough, including NVidia CUDA. A new storage API has also been added, allowing for the creation of multiple storage pools which can then be used to host containers or independent storage volumes. And a number of new images have been added, including support for Ubuntu Core 16.

DPDK

Ubuntu 17.04 includes the latest release of DPDK, 16.11.1.

As a tech preview DPDK is now also available for ppc64el. This includes the latest improvements made in version 16.11.1 in general, but also further improvements to enable the i40e PMD and vfio-pci scanning on spapr platforms.

OpenStack Ocata

Ubuntu 17.04 includes the latest OpenStack release. OpenStack Ocata is also provided via the Ubuntu Cloud Archive for OpenStack Ocata for Ubuntu 16.04 LTS users.

Cloud-Init

Cloud-init has been updated to be stricter when identifying the cloud platform that it is running on and searching for data sources.

 

Why You Might Want to Upgrade

One nice thing for home users is the availability of driverless printing. Driverless printing will allow users to install just about any modern IPP Everywhere or Apple AirPrint-compatible printer via USB or network without installing a printer-specific driver. This is a big plus to folks who don’t like going through the rigmarole of finding and setting up print drivers for CUPS.

Other updates to the 17.04 release include an upgrade to LibreOffice 5.3, and a week view in the calendar. Standard-issue desktop apps will also migrate to Gnome 3.24, with the exceptions to Terminal, Evolution (email client), the Nautilus file manager, and Software (app store).

If you want to roll with an updated kernel in 16.04 like the 4.10 kernel that was recently released, you can use the Linux-mainline PPA to get newer kernel packages. If you choose to go this route, do so with care and be sure to keep the kernel updated because Ubuntu doesn’t officially support kernels from the mainline PPA. Things can and will break by using an unsupported kernel.

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.

Docker says: “Available for both Windows and Mac” – WTF?

https://solace.com/wp-content/uploads/2017/03/docker-logo.pngDocker, Please – “Available for both Windows and Mac” Are you kidding?

This reminds me of the legendary line from the Blues Brothers movie:

“We got BOTH kinds of music – Country AND Western!”

Sheesh.

Lame – it’s all based on Linux!  And Open Source!

Docker runs natively on Linux – the only way to get it to run on Windows and/or Mac, is to run it inside a VM (Virtual Machine), running Linux.  Ahem.

So apparently that’s what this does, although you couldn’t tell by the name, the marketing blurb, nor the description.

DOCKER TOOLBOX

The Docker Toolbox is an installer to quickly and easily install and setup a Docker environment on your computer.

Available for both Windows and Mac, the Toolbox installs Docker Client, Machine, Compose and Kitematic.

Sigh.

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.
