For those who want to explore quantum computing and learn the Q# programming language at their own pace, we have created the Quantum Katas – an open source project containing a series of programming exercises that provide immediate feedback as you progress.
Coding katas are great tools for learning a programming language. They rely on several simple learning principles: active learning, incremental complexity growth, and feedback.
The Microsoft Quantum Katas are a series of self-paced tutorials aimed at teaching elements of quantum computing and Q# programming at the same time. Each kata offers a sequence of tasks on a certain quantum computing topic, progressing from simple to challenging. Each task requires you to fill in some code; the first task might require just one line, and the last one might require a sizable fragment of code. A testing framework validates your solutions, providing real-time feedback.
Programming competitions are another great way to test your quantum computing skills. Earlier this month, we ran the first Q# coding contest and the response was tremendous. More than 650 participants from all over the world joined the contest or the warmup round held the week prior. More than 350 contest participants solved at least one problem, while 100 participants solved all fifteen problems! The contest winner solved all problems in less than 2.5 hours. You can find problem sets for the warmup round and main contest by following the links below. The Quantum Katas include the problems offered in the contest, so you can try solving them at your own pace.
We hope you find the Quantum Katas project useful in learning Q# and quantum computing. As we work on expanding the set of topics covered in the katas, we look forward to your feedback and contributions!
Technology is changing the way people get things done. We’ve picked up the pace. Our work is more collaborative. And we’re blurring the boundaries of time and place. When we ask customers why they continue to choose Office for their most important work, they tell us that they love the power the Office apps offer. The breadth and depth of features is unmatched in the industry and allows them to do things that they just can’t do with other products. But they also tell us that they need Office to adapt to the changing environment, and they’d love us to simplify the user experience and make that power more accessible. Today, we’re pleased to announce user experience updates for Word, Excel, PowerPoint, and Outlook rolling out gradually over the next few months. These changes are inspired by the new culture of work and designed to deliver a balance of power and simplicity.
Office is used by more than a billion people every month, so while we’re excited about these changes, we also recognize how important it is to get things right. To guide our work, we came up with “The Three Cs”—a set of guiding principles that we use as a north star. Because these principles will make this process feel different than any previous user experience update, we thought it would be useful to share them with you.
Customers—We’re using a customer-driven innovation process to co-create the design of the Office apps. That process consists of three phases: initial customer research and analysis; concepting and co-creation; and validation and refinement.
Context—Customers love the power of Office, but they don’t need every feature at the same time. We want our new designs to understand the context that you’re working in, so you can focus on the job at hand. That means surfacing the most relevant commands based on the work you’re doing and making it easy to connect and collaborate with others.
Control—We recognize that established skills and routines are powerful—and that the way someone uses the apps often depends on specific parts of the user interface. So we want to give users control, allowing them to toggle significant changes on and off.
These updates are exclusive to Office.com and Office 365—the always up-to-date versions of our apps and services. But they won’t happen all at once. Instead, over the next several months we will deploy new designs to select customers in stages and carefully test and learn. We’ll move them into production only after they’ve made it through rigorous rounds of validation and refinement.
The initial set of updates includes three changes:
Simplified ribbon—A new, updated version of the ribbon is designed to help users focus on their work and collaborate naturally with others. People who prefer to dedicate more screen space to the commands will still be able to expand the ribbon to the classic three-line view.
The first app to get this new experience will be the web version of Word and will start to roll out to select consumer users today on Office.com. Select Insiders will then see the simplified ribbon in Outlook for Windows in July.
Word, Excel, and PowerPoint for Windows offer our deepest, richest feature set—and they’re the preferred experience for users who want to get the most from our apps. Users have a lot of “muscle memory” built around these versions, so we plan on being especially careful with changes that could disrupt their work. We aren’t ready to bring the simplified ribbon to these versions yet because we feel like we need more feedback from a broader set of users first. But when we do, users will always be able to revert back to the classic ribbon with one click.
New colors and icons—Across the apps you’ll start to see new colors and new icons built as scalable graphics—so they render with crisp, clean lines on screens of any size. These changes are designed to both modernize the user experience and make it more inclusive and accessible.
The new colors and icons will first appear in the web version of Word for Office.com. Then, later this month, select Insiders will see them in Word, Excel, and PowerPoint for Windows. In July, they will go to Outlook for Windows, and in August they will begin rolling out to Outlook for Mac.
Search—Search will become a much more important element of the user experience, providing access to commands, content, and people. With “zero query search,” simply placing your cursor in the search box will bring up recommendations powered by AI and the Microsoft Graph.
Commercial users can already see this experience in action in Office.com, SharePoint Online, and the Outlook mobile app, and it will start rolling out to commercial users of Outlook on the web in August.
For an overview of these changes, check out the video below by Jon Friedman, our chief designer for Office.
To develop these initial designs, Jon’s team worked closely with customers. They collected data on how people use the apps and built prototypes to test new concepts. While we have plenty of work left to do, we’ve definitely heard encouraging things from customers using early builds:
“It’s simpler and I feel like I can open it and immediately get my bearings and move forward. Not a lot of extra information. The tasks are obvious on this screen.”
“The toolbar provides the most frequently used features…maximizing the screen real estate for the actual content.”
“I like the extra space. What I do find is that the feature to toggle it off/on is helpful because occasionally I can’t figure out (quickly) where something went.”
We plan on carefully monitoring usage and feedback as the changes roll out, and we’ll update our designs as we learn more.
Technology is changing the way people get things done at work, at school, and at home, resetting expectations for productivity. Inspired by these changes, these updates are designed to deliver a balance of power and simplicity. But what’s most exciting for us is that over the next few months we’ll be co-creating and refining these new experiences with our customers—and making the power of Office more accessible for everyone.
The mobile device management space is growing at a rapid pace, and MDM is widely used across the enterprise to manage and secure smartphones and tablets. Investing in this technology enables organizations to not just secure mobile devices themselves, but the data on them and the corporate networks they connect to, as well.
The market for MDM software is saturated now, and there are new vendors arriving in this vertical on a consistent basis. Many of the larger names in mobile security, meanwhile, have been buying up smaller vendors and integrating their technology into their mobile management offerings, while others have remained pure mobile device management companies from the beginning. So what are the best mobile device management products available today?
Since the mobile security market has become so crowded, it is harder than ever to determine what the best mobile device management products are for an organization’s environment.
To make choosing easier for readers, this article evaluates five leading EMM companies offering MDM as a part of their bundles and their products against the most important criteria to consider when procuring and deploying mobile security in the enterprise. These criteria include MDM implementation, app integration, containerization vs. non-containerization, licensing models and policy management. The mobile management vendors covered are Good Technology Inc., VMware AirWatch, MobileIron Inc., IBM MaaS360, Sophos and Citrix.
That being said, there are also niche players — such as BlackBerry — that are attempting to move into the broader MDM market outside of just securing and managing their own hardware, in addition to free offerings from the likes of Google that have attempted to compete with the above list of MDM vendors by providing tools to assist in Android device management. Even Microsoft has a small amount of MDM built into its operating systems to manage mobile devices.
Today, the vast majority of mobile devices in use — both smartphones and tablets — run on either Apple’s iOS or Google’s Android OS. So while many of today’s MDM products are also capable of managing Windows Phones, BlackBerry devices and so on, this article focuses mostly on their Apple and Android management and security capabilities.
Selecting the best mobile device management product for your organization isn’t easy. By using the criteria presented in this feature and asking six crucial questions before buying MDM software, an organization will find it easier to procure the right mobile management and security products to satisfy its enterprise needs.
Criteria #1: Implementation of MDM
Organizations should understand and plan out their mobile device deployment and MDM requirements before looking at vendors. The installation criteria for MDM are normally based on a few things: resources, money and hardware. With that being said, there are two distinct installation possibilities when deploying an MDM product.
The first is an on-premises implementation that needs dedicated resources, both from a hardware and technical perspective, to assist with installing the system or application on a network. Vendors like Good Technology with it’s Good For Enterprise suite require the installation of servers within an organization’s DMZ. This will necessitate firewall changes and operating system resources to implement.
These systems will then need to be managed appropriately to verify that they’re consistently patched and scanned for vulnerabilities, among other issues. In essence, this type of MDM deployment is treated as an additional server on an organization’s network.
It’s possible that a smaller business might shy away from an install of this nature due to the requirements and technical know-how it would take to get off the ground. On the other hand, if businesses are able to manage this type of mobile management and security product, it gives them complete ownership of these systems and the data that’s on them.
The second installation type is a cloud-based service that enables an off premises installation of MDM, removing any concerns regarding management, technical resources and hardware. Vendors like VMware AirWatch and Sophos have the ability to let customers provision their entire MDM product in the cloud and manage the system from any internet connection. This is both a pro and a con: It provides companies with resource constraints — like not having the experience or headcount — with the ability to get an MDM product set up quickly, but it does so at the risk of having data reside outside the complete control of these organizations — within the cloud.
Depending on an organization’s resource availability, technical experience and risk appetite, these are the two options — on-premises and cloud — currently available for installing MDM.
Criteria #2: App integration
Apps are a major reason mobile device popularity and demand has increased exponentially over the years. Without the ability to have apps work properly and yet securely, the power of mobile devices and the ability for users to take full advantage of these tools becomes severely limited.
MDM companies have realized this need for functionality and security, so they’ve created business-grade apps that enable productivity without compromising the integrity of mobile devices, the data on them and the networks to which they connect.
Citrix XenMobile has created XenMobile Apps that are tied together and save data in a secure sandbox on mobile devices, so users don’t need to use unapproved apps to send business data to potentially insecure apps out of an enterprise’s control. The sandboxing technology works by securing, and even at times partitioning, the MDM app separately from the rest of the mobile OS — essentially isolating it from the rest of the device, while allowing a user to have the ability to work securely and efficiently.
There are also third-party app vendors that MDM vendors have partnered with to create branded apps. Good Technology has, for example, partnered with many large vendors to accommodate the need to use their apps with a specific MDM environment. This integration between vendors is extremely helpful and adds to the synergy between both vendors to create better security and more productive users. Sophos also allows this with their Secure Workspace feature, which enables users to access files within a container while securing the access to these documents.
Whether you’re using apps created by an MDM vendor for additional security, or apps that have been developed through the collaboration of an MDM vendor and a third-party vendor, it’s important to know that most of the work on a mobile device is done via these apps, and securing the data that flows through them and is created on them is important.
Criteria #3: Container vs. non-container
There are two major operational options available when researching MDM products: MDM that uses the container approach and MDM that uses the non-container approach. This is a major decision that needs to be made before selecting a mobile management product, as most vendors only subscribe to one of these methods.
This decision, whether to go with the container or non-container method of mobile management, will guide the device policy, app installation policy, BYOD plans and data security for the mobile devices that an organization is looking to manage.
A containerized approach is one that keeps all the data and access to corporate resources contained within an app on a mobile device. This app normally won’t allow access to the app from outside the mobile device and vice versa.
Both the Good for Enterprise suite and MaaS360 offer MDM products that enable customers to use a containerized approach. Large companies tend to benefit from this approach — as do government agencies and financial institutions — as it tends to offer the highest degree of protection for sensitive data.
Once a container is removed from a mobile device, all organizational data is gone, and the organization can be sure there was no data leakage onto the mobile device
In contrast to the restricted tactic used by containerization, the non-container approach creates a more fluid and seamless user experience on mobile devices. Companies like VMware AirWatch, Sophos and MobileIron are the leaders in this approach, which enables security on mobile devices via policies and integrated apps. This means these systems rely on pushing policies to the native OS to control their mobile devices. They also support multiple integrated apps — supplied by trusted vendors the MDM companies have partnered with — that assist in adding an additional layer of security to their data. These companies also allow the use of containers and help bridge the gap between customer needs.
Many organizations, including startups and those in retail, lean toward the non-container approach for mobile management and security due to the speed and native familiarity that end users already have with their mobile devices — with OS-bundled calendaring and mail apps, for example. However, keep in mind, in order to completely secure all the data on mobile devices, the non-container approach requires the aforementioned tight MDM policies and integrated apps to enforce the protection of data.
Criteria #4: License models
The licensing model for MDMs has changed slightly in recent years. In the past, there was only a per device license model, which meant organizations were pushed into using licensing models that weren’t very effective for them financially. Due to the emergence of tablets and users carrying multiple smartphones, there became the need to have a license model based on the user — and not the individual device.
All the MDM products covered in this article offer similar, if not identical, pricing models. MDM vendors have listened to the customers and realized that end users in this day and age don’t always have one device. Which licensing model an organization chooses — per device or user based — depends on the company’s mobile device inventory.
The per-device model normally works well for small companies. In this model, every user gets a device that counts against the organization’s total license count. If a user has three devices, all of these go against the total license count of the business. These licenses are normally cheaper per seat, but can quickly become expensive if there are multiple devices per user requiring coverage.
The user-based pricing model, by contrast, takes into account the need for users to have multiple devices that all require MDM coverage. With this model, the user name is the basis of the license, and the user can have multiple devices attached to his one license. This is the reason many larger organizations lean toward this model, or at least a hybrid approach of the two licensing models — to account for users who use multiple mobile devices.
MDM criteria #5: Policy management
This is an important feature of mobile device management, and one that organizations need to review with either a request for proposal (RFP) or something that outlines the details of what mobile device policies they require. Mobile policies enable organizations to make granular changes to a mobile device to limit certain features — the camera and apps, among others — push wireless networks, create VPN tunnels and whitelist apps. This is the nuts and bolts of MDM, and a criterion that should be reviewed heavily during the proof-of-concept stage with specific vendors.
This ability to push certain features of a policy to mobile devices is certainly required, as is the ability to wipe devices remotely if the need occurs should they be lost or stolen. While all the MDM products covered in this article provide the ability to remotely wipe mobile devices, in the case of Good for Enterprise and IBM MaaS360, organizations have the option to wipe mobile devices completely or to just remove the container.
Also important for MDM products is the ability to perform actions such as VPN connections, wireless network configurations and certificate installs, which AirWatch can accomplish. Sophos also offers the ability to manage policies from a security perspective by enforcing antiphishing, antimalware and web protection.
You must assert these options in an RFP beforehand to determine what part of the mobile device policy you’re looking to secure. Evaluating what policy changes you can push to a mobile device and what functions an organization might want to see within a policy will help provide insight for an educated decision on the best mobile device management products.
Most times there will be multiple policies created that allow certain users to receive a particular policy, while allowing someone with other needs to receive a completely different MDM policy. This is a standard function within all MDMs, but it should be understood that a single policy for all users is not always plausible.
Finding the best mobile device management product for you
There are many vendors in this saturated market, but following these five criteria should assist organizations in narrowing the field down to find the best mobile device management products available today. There is much overlap between vendors, but finding the right one that can secure an organization’s data completely and offer full coverage, with the ability to manage all the aspects needed in a policy, is what businesses should be aiming for in MDM products.
Many large companies, especially those in the financial or government sector, are running Good for Enterprise due to the extra layer of security it provides by leveraging a container and integrated apps developed by vendors with whom they partnered.
IBM MaaS360, on the other hand, offers both a container and non-container approach to mobile security and management, which makes it suitable for larger enterprises that require some flexibility in terms of operational method deployment. This gives IBM MaaS360 the ability to play to both sides and gives them some leverage over competitors by attracting customers from both mindsets.
Many midsize companies don’t have to meet the level of security imposed by large financial clients, though, and thus aren’t running to boost their mobile device security. We’ve seen that, many times, compliance will bring an extra layer of required security, however, thereby making these organizations more conscience at times about securing data on mobile devices.
Midsize to large companies — those outside of the financial sector — tend to run AirWatch, Sophos or MobileIron MDM due to their abilities to keep the native feel of mobile devices intact, while being able to push custom policies that secure mobile devices to the clients.
As for app integration, Citrix has performed very well in this area with XenMobile, having shown that it’s pushing the boundaries of this area. These apps are selling points to many customers who want to integrate their data onto a mobile device, but want the flexibility to manage the data these mobile apps are consuming. By dispensing these approved apps to managed mobile devices and writing policy for their data to be used on these apps, MDM products, such as Citrix’s, assist with adding an extra layer of data control for the company and ease of use for the user.
As mobile devices become more indispensible for business users, the MDM market will keep expanding in response to the growing need for mobile security.
Evolution doesn’t occur at a steady pace. It’s marked by moments of a consequential and relatively sudden change, which significantly alter survival dynamics and give rise to entirely new paradigms.

This happened with the Cambrian explosion. Approximately 541 million years ago, and over the next 70 million to 80 million years, organisms rapidly evolved from mostly single-cell to complex and diverse creatures that better resemble life on planet Earth as we know it.
As CloudBees CTO and Jenkins founder Kohsuke Kawaguchi explained in his Jenkins World keynote, the Cambrian explosion serves as an apt metaphor for both Jenkins and the DevOps digital transformation.
Otherwise mundane elements sparked and fueled the Cambrian explosion, like the gradual evolution of eyesight. While crude at first, many experts believe eyesight reached a tipping point that upheaved the predator-prey dynamic by enabling predators to hunt more effectively. This increased pressure to evolve and kicked off an arms race, as prey developed better defense features, like armor, speed and camouflage.
Automation, cloud and mobile: Fueling the DevOps digital transformation
For Jenkins, which started as a single app for a single use case, the automation features in early builds stand in for eyesight, while mobility and cloud serve the same for DevOps as a whole. Modern software as we know it has been around for about 70 years. But it’s easy to see mobility, cloud and automation, igniting software’s Cambrian explosion.
All were limited and seemingly innocuous at first, but eventually developed to enable an online broker like Amazon to compete with Walmart, the world’s largest physical retailer. The pressure to evolve is why Walmart dropped $3 billion on e-commerce startup Jet.com earlier this year. The pressure to evolve is why all business are now in the software business — a refrain repeated at Jenkins World.
Evolution equals transformation, and the latter was a steady theme at Jenkins World; although, both could just as easily double as warnings. CloudBees CEO Sacha Labourey hit that point home in his keynote focusing on “Digital Darwinism,” quoting Eric Shinseki, retired Army general and former U.S. secretary of Veteran Affairs: “If you dislike change, you’re going to dislike irrelevance even more.”
Instant insights, the next big thing
CloudBees used Jenkins World to launch DevOptics, which Labourey claimed provides a “single source of truth” for a “holistic view” of the deployment pipeline, aggregating data from disparate tools and teams. From his description, it’s a DevOps system of record — one that ultimately helps the business side “identify ROI from DevOps initiatives,” according to CloudBees.
CloudBees was’’t alone in trying to make metric sense of the deployment pipeline. Electric Cloud recently unveiled ElectricFlow 8.0 with DevOps Insight Analytics, using Jenkins World to show it off to prospective developers. According to Electric Cloud, Insight Analytics provides “teams with automated data collection and powerful reporting to connect DevOps toolchain metrics and performance back to the milestones and business value (features, user stories) being delivered in every release.”
Anders Wallgren, CEO at Electric Cloud, based in San Jose, Calif., stated it offered instant insights to relevant pipeline analytics, helping troubleshoot bottlenecks and spot trends, for both IT and business leaders.
So, what’s the big deal about dashboards and insights? Plenty, according to Kawaguchi — particularly CloudBees Blue Ocean. He said he sees it as another element fueling the DevOps digital transformation.
A friendly UI that both business and IT can understand improves the constant delivery user experience. Think of it as extending the pipeline beyond IT to business and marketing. With relevant insights, organizations can better meet customer needs and react to customer demands.
It’s both an evolutionary and revolutionary software explosion, fueled by cloud, mobile, automation and easy access to actionable data. Take another look at Walmart as it scrambles to stave off Amazon, or at Marriott and Hilton doing the same with Airbnb. Look at Tesla and it’s software fix to its hardware problem. It’s already here, altering survival dynamics and giving rise to entirely new paradigms.
