oVirt System Tests to the Rescue!—How to Run End-to-End oVirt Tests on Your Patch

Today, when an oVirt developer pushes a patch to review on oVirt Gerrit, various validations are triggered in CI via the 'check-patch' job, as defined by the project maintainers. Usually these jobs includes 'unit-tests', 'db tests', static analysis checks, and even an occasional 'functional test'. While it might seem that it covers alot and gives a good indication that the patch is good to be merged, unfortunately it is not always the case.

The reason it's not enough lies in oVirt's complexity and the fact it's a Virtualization project, which means the only real way to know if your patch didn't break things is to install oVirt and try running a few basic commands, like 'adding host', 'adding vm', 'creating snapshots', and other tasks you can only do if you have a full oVirt system up and running. Here is where OST comes in!

oVirt System Tests

oVirt system tests is a testing framework written in Python, using 'python-nose' and oVirt Python SDK and runs on auto-generated VMs created by Lago. It is used by the oVirt CI to run post merge end-to-end testing that runs on a fully deployed oVirt environment and has been proven to detect multiple regressions Continue reading

Lenovo’s new ThinkPad X1 devices get sexier designs, faster chips

The venerable ThinkPad brand will turn 25 this year, and Lenovo's new ThinkPad X1 devices will kick off celebrations with a slew of upgrades including sexier designs, faster processors, and screens with thinner borders.The new ThinkPad X1 Carbon laptop (starting at US$1,349), ThinkPad X1 Tablet (starting at $949) and ThinkPad X1 Yoga 2-in-1 (starting at $1,499) are smaller, thinner and lighter than ever before. In addition, the devices have much longer battery life.Many of the advances come thanks to the upgrade to Intel's 7th Generation Core processors code-named Kaby Lake. The integrated GPUs are faster and provide the capability to support 4K video processing.To read this article in full or to leave a comment, please click here

Lenovo primes to take on Microsoft’s next Surface tablet with Miix 720

The world is waiting for Microsoft's next Surface tablet, but when it ships, it'll have to contend with Lenovo's new Miix 720, a 12-inch Windows tablet loaded with cutting-edge features. The Miix 720 will start at US$999 and will ship in April. That's about $100 more than the starting price of the Surface Pro 4, but the Miix 720 has superior features. But the Surface could catch up with the Miix 720 soon. A new Surface Pro 5 could be out as soon as early this year and have features like faster processors and a higher resolution screen that could on par or better than the Miix 720. That's when the competition will get interesting. But for now, it's Miix 720 versus the Surface Pro 4. The Lenovo tablet runs on an Intel Core processor based on the latest Kaby Lake architecture and has an integrated graphics processor capable of supporting 4K video. Surface Pro 4 is a generation behind with Skylake chips, but the next Surface tablet will likely get Kaby Lake.To read this article in full or to leave a comment, please click here

Lenovo crashes gaming party with new Legion line of laptops

Gaming enthusiasts are particular. They like colorful chassis, bright keyboard lights, cool-sounding brand names and scintillating performance in PCs.Those are ideals Lenovo has embraced with its new Legion line of gaming laptops and PCs. Introduced on Tuesday, Legion will feature some of the most loaded PCs offered by Lenovo.In a way, Legion is to Lenovo what Alienware is to Dell -- a product family that will help Lenovo cash in on PC gaming and virtual reality. Beyond PCs, the Legion brand could also include gaming monitors and accessories.Lenovo isn't known as a game PC maker, but it isn't stretching outside its comfort zone with Legion. It already offers Y-series and IdeaPad gaming PCs, and has partnered with Razer to build not only desktops, but keyboards with lighting effects and other gaming accessories. Lenovo hopes Legion -- a name coined after the large units in the armies of the Roman empire -- will resonate with gamers.To read this article in full or to leave a comment, please click here

My (Evolving) Multi-Platform Toolbelt

A few days ago I posted a tweet about a new tool I’d (re-)discovered called jrnl. Someone replied to that tweet, asking me to list my “multi-platform toolbelt.” While it’s still evolving (every day!), I thought it might make for a good blog post. So, here’s a list of my still-evolving multi-platform toolbelt.

• Sublime Text: Over the last few years, I’ve moved to creating the vast majority of my content in Markdown (MultiMarkdown, to be more specific). At first I was using OS X-specific text editors (first TextMate 1.x, then BBEdit), but last year I switched to Sublime Text. Sublime Text supports OS X, Linux, and Windows. I don’t have any Windows-based systems, so I only use it on OS X and Linux.

• Wire: My use of Wire is still a bit limited, but only because the reach of the platform is also still a bit limited (this is a classical example of network effect). I’m currently using Wire on Linux and OS X, with plans to extend to iOS and Android. (If you’re using Wire, feel free to look me up! My username is “scottslowe”).

• IMAP/SMTP: I’ve standardized on using IMAP/SMTP for all my e-mail Continue reading

Worth Reading: Monitoring in containers

Monitoring is the hidden hero inside container infrastructure. Much like driving a car, we don’t think about what’s happening under the hood until something goes wrong. We want to pivot away from being reactive with our infrastructure and container problems and move to a more proactive state of operation using monitoring insights to keep us up and running. —The New Stack

A New Year’s Resolution for your Intranet: Do an IA Health Check!

I spent a lot of time in 2016 working on more information architecture (IA) projects than usual – from designing comprehensive information architectures as part of intranet migrations or upgrades to small IA usability engagements and everything in between. Here are six key lessons that I learned that can form the basis of your new year’s resolution to give your intranet IA a health check.The Information Architecture for your intranet provides the strategy and plan for information access. It informs how users will navigate through the solution and how information managed by the solution will be organized. A good intranet information architecture is 100% focused on the people who need to process, find, and interact with the content. We mostly think of IA as supporting the “browse” experience. But, given the fact that search depends on metadata, which is part of your IA, a good IA is also supports search. If you get it right, your information architecture will help users find content in three critical content-finding scenarios:To read this article in full or to leave a comment, please click here

Looking Back, Looking Forward

On this, the first “real” post of 2017, I thought it would be useful to reflect on the year that has passed, and consider the year that is coming. First off, 2016 in numbers—

• Read 58 Books (15333 pages)
• 115,739 blog visits (according to WordPress)
• Wrote 110,000 words for blogs, technical papers, etc.
• Wrote 25,000 words for PhD seminars, etc.
• Created 850 slides
• Recorded 14 hours of videos/webinars

These are all conservative numbers for the most part… I’ve not included journal and blog reading, nor have I tried to accurately count my writing output, as I often find it more frustrating than worthwhile. In the coming year, I plan to finish a book with Pearson, record at least one more video series (potentially more), and continue apace with blogging and other writing.

In 2016, I think we started to see the future of the networking market actually take shape. There seem to be three prongs developing; either companies will move their processing to the cloud, they will move to more hyperconverged/vertical solutions (essentially outsourcing design and architecture to vendors and consulting firms), or move to disaggregation. The day of the router as an appliance is done; we are moving to Continue reading

Donald Trump offers cybersecurity warning: ‘No computer is safe’

Donald Trump showed off his IT security credentials at a New Year's Eve party, suggesting that the best way to keep secrets from hackers is a huge air gap."No computer is safe," he told journalists gathered at his Mar-A-Lago resort in Florida, a warning many computer security professionals would probably endorse.Trump also shared his advice on managing data security risks. Forget switching to TLS or quantum key exchange: "If you have something really important, write it out and have it delivered by courier," he said, according to a report from Associated Press.Trump's suggestion -- echoing his July 29 infosec advice for military commanders -- would put the biggest of airgaps around secret communications, ensuring that they could not be hacked into from afar. If he were to apply it to government communications, though, it would leave officials needing a veritable army of trustworthy little hands to carry messages.To read this article in full or to leave a comment, please click here

Efficient storage: how we went down from 50 PB to 32 PB

As the Russian rouble exchange rate slumped two years ago, it drove us to think of cutting hardware and hosting costs for the Mail.Ru email service. To find ways of saving money, let’s first take a look at what emails consist of.

Indexes and bodies account for only 15% of the storage size, whereas 85% is taken up by files. So, files (that is attachments) are worth exploring in more detail in terms of optimization. At that time, we didn’t have file deduplication in place, but we estimated that it could shrink the total storage size by 36% since many users receive the same messages, such as price lists from online stores or newsletters from social networks containing images and so on. In this article, I’m going to describe how we implemented a deduplication system under the supervision of Albert Galimov.

Worth Reading: Getting started with coding

If you work with computers in any aspect of your life, being able to code can be a very powerful tool. All too often however, I hear people say things like “it’s too difficult” or “I’m not a developer” and they never take more than their first few steps. This post, the first in a series on getting started with coding, addresses both the fears of taking your first steps and the benefits of starting that journey. The remaining posts then give you all the help you need to overcome those perceived obstacles and have some fun along the way. —vegaskid

Cops to increasingly use digital footprints from IoT devices for investigations

If Mark Stokes, Scotland Yard’s head of digital, cyber and communications forensics unit, is correct, then IoT devices will play an increasingly important role in crime scene investigations. “The crime scene of tomorrow is going to be the internet of things,” Stokes told the Times.The police are being trained to look for “digital footprints” – IoT gadgets that “track or record activities” which might prove or disprove alibis and witness statements as well as record what occurred during a murder victim’s final moments.Cops will be relying on evidence from smart devices which spy on you – such as internet connected refrigerators, light bulbs, washing machines, vacuum cleaners, coffee makers and voice-controlled robotic assistants.To read this article in full or to leave a comment, please click here

Hands on: Dell twists the XPS 13 into a 2-in-1

Dell has just improved its already brilliant XPS 13 -- it will now be available as a 2-in-1, which means the device has the versatility to be a laptop or a tablet. I had the chance to play around with the device prior to CES. It has a clever design and wowed me with its sleek design and edge-to-edge screen, but it won't come cheap. The starting price of the XPS 13 2-in-1 is US$999, and it'll start shipping this month. That's about $200 more than the starting price of the XPS laptop. You are paying more for the versatility of the XPS 13 2-in-1. On the outside, the XPS 13 2-in-1 looks like the XPS 13 laptop, but Dell has changed the hinge connecting the keyboard base and screen. The screen can be rotated 360 degrees to turn the device into a tablet.To read this article in full or to leave a comment, please click here
