Rackspace Serves Up Free Carina Docker-Based Container-as-a-Service Beta on OpenStack

Using the native Docker API and tooling, the Carina container service aims to enable users to spin up containers quickly and easily. 

Until its probable general availability next year, the beta version of the Carina container service unveiled today by Rackspace will be free. It offers developers, data scientists, and operators what the web-hosting firm says is a quick way to create and deploy a cluster for containerised apps. Demonstrated at this week’s OpenStack Summit conference in Tokyo, Carina is designed to widen the use of container clusters, employing the native Docker API and tooling, such as Swarm for orchestration, to move applications between dev, test, and production environments.

Solu Mini-PC Taps Linux for Organic Cloud UI

solu-collab copyA Finnish startup called Solu Machines is closing in on its Kickstarter funding for a smartphone-like mini-PC with a Linux-based, cloud-oriented operating system and a novel UI stack. Funding packages start at $388 for the Solu, which would join a fairly short list of mini-PCs with pre-installed Linux, and an even smaller group of ARM-based Linux mini-PCs. Solu is much more singular than that, however, in that it’s a battery-powered touchscreen device that can also drive a 4K display. It is not only replacing standard PC and phone paradigms with a fully cloud-based platform, but is also reinventing the user interface.

Solu’s SoluOS, which was confirmed by Softpedia to be built around Linux, aims to help users “share documents and applications and work co-cooperatively,” says Solu. The cloud-oriented platform provides unlimited access to SoluOS apps, as well as encrypted storage, with automatic maintenance and backup, and “without any annoying in-app purchases or advertisements.” The device, which also works offline, will support “legacy” Android apps as well, says Solu Machines.

The intriguing SoluOS interface is based around network diagrams linked to various projects. Instead of looking for specific apps and documents, you zoom in on content based on projects. The design has an organic look and feel, while at the same time looking like something you might see on the bridge of an alien spaceship.

The Solu runs SoluOS on a “4-Plus-1” Nvidia chip, which would appear to be the Tegra K1. The 2.3GHz, quad-core, Cortex-A15 SoC features Nvidia Kepler graphics with 192 CUDA cores. The 102x102x13mm device has a wooden exterior except for the square, 1440×1440-pixel, 450ppi, edge-to-edge touchscreen. There’s no mention of a display port, so it would appear Solu uses the sole USB Type C port to plug into a monitor and drive a 4K display. The 1200mAh battery powered Solu ships with 4GB of LPDDR3 RAM and 32GB of local storage, and provides dual-band WiFi (802.11a/b/g/n) and Bluetooth 4.0.

Early bird Kickstarter packages for the Solu are available through Nov. 14 for 349 Euros ($388), a discount from the eventual retail price of 449€, with shipments starting in May 2016. The price includes three free months of access to Solu’s cloud platform, which will normally cost 20€ (about $22) per month. A 749€ package gets you an early version in January.

Reinventing the Interface

It takes courage to attempt a completely novel UI like SoluOS. The fact that innovative interfaces rarely succeed doesn’t mean we shouldn’t keep trying to reimagine the way we interact with computers. Maybe it’s just a Finnish thing, as the Linux-based Sailfish OS from Finland-based Jolla also pushes the limits of our mobile UI expectations, although not as dramatically.

With its rounded, square-shaped, wooden exterior, and novel Linux-based UI, Solu seems a bit like Monohm’s Firefox OS-based Runcible, but without the cellular telephony and round display. With its support for large-screen displays, Solu is also somewhat similar to Canonical’s vision for its Ubuntu Phones, and its cloud-based approach, meanwhile, reminds one of Chrome OS.

The fluid, spider web-like UI brings to mind other unusual interfaces that have popped up from time to time. One of the weirdest was a fan-like UI that appeared on the LiMo (Linux Mobile) based Else phone. The Else wowed the media in demos back in 2009 but never shipped. (LiMo, meanwhile, went on to form a good chunk of Tizen.)

It’s certainly not a coincidence that all of the above listed products run Linux. Open source projects have a way of making the impossible seem possible. As for open source, however, Solu Machines says only that “We are looking into possibilities to open source part or all of the work.” The app development model is also unclear. “We are providing talented developers with the opportunity to make a living out of their great apps by sharing a portion of the monthly fee with them,” says Solu.

Without great assurances of open source licensing and governance, or at least a clearer path to profits, Solu may have trouble attracting developers. Beyond the considerable challenges of launching a new computing ecosystem, Solu faces some more specific obstacles. The starting price is fairly high for a device with minimal features and without cellular support, and the $22 a month subscription may also give potential users pause. Solu also faces the same user expectation gaps that Google had with Chrome OS. The Solu FAQ concedes that there will initially be limited support for printers and scanners, with support improving over time.

The Kickstarter page text and videos provide plenty of inspiring talk about changing the world, including a stirring video from Finnish rapper Paleface defying the inevitable critics to howl. Yet, there are relatively few details on how the software works, or how users will collaborate on documents. The company cannot specify how it will achieve Android compatibility except to say that for now it is using the adb command-line interface.

Still, with 17 days to go, Solu seems likely to make its goal of $227,812.00, and it already has $1.3 million in seed investments. Assuming the collaboration tools are there, along with the rest of the technology, one can conceive of startups or highly mobile corporate teams buying a bunch of Solus for its team members to keep them focused on projects with limited distractions.

In any case, close to 500 Kickstarter backers have either acquired an inside track on the new computing paradigm or an interesting, wooden-backed conversation piece they can someday donate to the Computer History Museum. Changing the face of computing is not without a little risk.

Companies That Support Linux: Rausch Netzwerktechnik

Rausch-logoRausch Netzwerktechnik is a distributor of individual and standard server and storage systems for the data center. The company is also developing one of the first solutions around the Kinetic Open Storage Project. We talked to Rausch Netzwerktechnik CEO Sebastian Nölting to learn more about the company and their involvement with open source.

Can you tell us more about Rausch Netzwerktechnik? What does the company do?

Since 1998, Rausch Netzwerktechnik has been working as a distributor of individual and standard server and storage systems for data centers and can relate on more than 250,000 systems in data centers across the globe. With a wide range of high-quality products for server, storage, and cloud computing, Rausch offers the perfect solutions for the DC business. Beginning with the development and manufacture followed by delivery, installation, and maintenance.

When was the company founded, who were the founders, and what was the motive?  

SN 6208 copyThe founder was Bernd Rausch in 1998. He sold the company in 2008. In 2015, I made a management buyout and now, with a friend, hold 100% of the shares. Since the beginning, we have been selling hardware for the data center, especially for Internet Service Providers. Most of them were standard server systems, then later more and more customized systems. The most important point was to increase the density and/or the efficiency. Power consumption is a big problem of data centers, and we always try to optimize our systems. In the meantime, we are selling to data centers all over the world, most of them are service providers or in the HPC sector.

What kind of products do you offer, and are they all open source?

All our storage systems are open source compatible. We have a family of storage offerings with different features:

System with Mainboard: BigFoot Flash is an all flash system with up to 52 SSDs in 2U; BigFoot Storage XXLarge is an all-rounder with 48 HDDs + 24 SSDs. The highest density worldwide in the shortest chassis. BigFoot XXCold is a cold storage for archive and lowest power consumption. The target is tape replacement.

System without Mainboard: BigFoot Object. Developed for Seagate Kinetic. We are the first and only manufacturer in Europe with a solution for Kinetic and with the highest density worldwide (72 disks in 4U and 750mm depth).

What market segments do you target?

Data centers of service providers, HPC, universities, and every customer with the need of high-density storage.

How are you involved with the Kinetic Open Storage Project?

We developed one of the first solutions around the Kinetic HDD. In 2016, we will have the next generation of our box with more internal and external bandwidth.

What kind of problems is the Kinetic Open Storage Project working to solve?

Less TCO for data centers with the need of >10PB of storage.

The Kinetic Open Storage Project is a collaborative project under the Linux Foundation. What are the benefits that you see of being part of such a project?

Kinetic is a new platform. We have a solution for this platform. Potential customers are not informed and want to get information about Kinetic. I can see this at the exhibitions, that the most people know that this exists. But Kinetic users are Linux-minded. To bring information about Kinetic through the Linux Foundation to the customer to get more visibility and awareness in the target group is a perfect way.

How does it help your company and your customers?

For us, we can go into new markets and become visible worldwide, because we are one of a handful of companies who have a solution for Kinetic. Our customers get the complete solution from one source: consulting, architecture, installation, and maintenance.

How important is open source for your company?

All important service providers are now working with open source. It is absolutely necessary that we are compatible.

Open source is becoming extremely popular in Europe. What’s driving this adoption?

In my market, open source has been important since the beginning. I think with the growth of data center, storage capacities, and server quantities, and with the growing cloud business, the commercial solutions are no longer attractive, and the customers are looking for alternative solutions with more flexibility and lower costs.

Why It Is Not Expensive To Spend 30% Of The total project time on testing

If you ask our project managers what is the worst ever idea to reduce the costs of app development, their answer would probably be:
“Fire the testers!â€
During product development, issues emerge when the de facto results deviate from the expected ones. Usually they are called bugs or errors and someone has to deal with them–find, describe, and avoid them. Usually, people think that testers examine the projects and this is true. However, this is only part of the testers’ job as testing starts far earlier.
In this article, we would like to discuss the general problems that testers solve every day and show why they are equally as important as the other team members.

1. Can developers avoid bugs?
It is impossible to avoid bugs during the development phase. However, it is possible to minimize or even eliminate their influence on the end product when the team organizes the testing process in the proper way.

2. Why do projects need tests?
Testing is a series of steps aimed at making a software product meet all requirements (and achieve this goal within optimal time limits), and, thus, it simultaneously examines all possible user scenarios. Results are the basis of any successful testing, i.e. your software will function exactly as expected and any features the team implemented during the development phase will work correctly.

3. When does testing start?
Any project starts from an idea, then the team formulates the scope of the project. Next, the technical experts, together with the customer, create the design of the project and write documentation, and only after that the development process starts. It is a mistake to believe that testing begins only when the coding is finished. Testing begins when the technical documentation writing starts as testers are full members of the technical expert team. When the business analysts describe all functions to the full extent, testers help them check whether the chosen solution allows them to scale the project, grants use of various platforms, and, most importantly, does not contain contradictions.

Linux / Open Source on Churches

There’s a lot of churches that I know that use pirated software from Operating System, Office Applications, Accounting, to Lyrics/Bible Projection.

How sad to think that many of IT / Computer Technicians working in churches are using their skills in a very wrong way.

I think Its time to correct things by recommending them to buy license or use alternative open source software that are needed by church.

I talked to church heads about this and open about open source alternative software getting their responses that they are not aware that there are available free open source sofware that they can use as an alternative to commercial software.

Below are highly recommended alternative softwares that are capable of running a church without any amount to spend.

  1. LXLE – Light Operating System (for old and new PCs/Laptops)
  2. OpenLP – Lyrics and Bible Projection Software
  3. Quelea – Lyrics and Bible Projection Software
  4. LibreOffice – Office Suite
  5. Audacity – Audio recording and editor
  6. Open Broadcaster – Video Recording and Live streaming
  7. VLC – Video / Music player
  8. GIMP – Image Manipulator
  9. digiKam – Photo Management
  10. Converseen – Batch Image Processor
  11. KMyMoney – Personal Finance Manager
  12. Thunderbird – Email application
  13. Firefox – Web browser
  14. Chromium – Web browser
  15. Brasero – CD/DVD Burning Application
  16. Rhythmbox – Music Player
  17. Bibletime – Bible Study Software

And many more.

Hope to correct things as we help each other and share His glory.

God bless Open Source.

How OpenStack’s Project Navigator Aims to Steer Users’ Cloud Choices

Tapping into data from a range of sources, including user surveys, the new online Project Navigator tool from the OpenStack Foundation is designed to help firms pick through open-source cloud components. To help users weigh up the options when designing and configuring their clouds, the OpenStack Foundation today lifts the lid on a new online tool it says will aid that process.

The aim of OpenStack’s Project Navigator is to enable firms to make sense of the various component projects, providing details on issues such as the software’s level of maturity, the quality of documentation, and the extent of its adoption.  The OpenStack open-source project was started in 2010 by Rackspace and NASA to create components for building public and private clouds on standard hardware.
