Microsoft democratizes quantum computing!

Published by:

Microsoft just released the Quantum Development Kit, taking a first bold step towards the democratization of quantum computing. Few months ago, the Redmond based company officially published a lot of their internal research and quantum computing roadmap, hence the release of the development kit was an event heavily expected by computer science enthusiasts. With the Quantum Development Kit, developers all around the world can now write quantum computing algorithms dive into deeper into concepts that till now we were able only to speak out to impress everybody around us.

The new released Quantum Development Kit contains the following:

  1. Q# language and compiler. Q# is a domain-specific programming language used for expressing quantum algorithms. It is used for writing sub-programs that execute on an adjunct quantum processor under the control of a classical host program and computer.
  2. Q# standard library. The library contains operations and functions that support both the classical language control requirement and the Q# quantum algorithms.
  3. Local quantum machine simulator. A full state vector simulator optimized for accurate vector simulation and speed.
  4. Quantum computer trace simulator. The trace simulator does not simulate the quantum environment like the local quantum simulator. It is used to estimate the resources required to execute a quantum program and also allow faster debugging of the non-Q# control code.
  5. Visual Studio extension. The extension contains templates for Q# files and projects as well as syntax highlighting. The extension also installs and creates automatic hooks to the compiler.

Thoughts about the future of technology

Published by:

Technology evolves on a very fast pace and it’s often difficult to predict the future of technology or some specific directions that technological development will head to. Still, last week there was an event that unarguably defines some strategic directions that technology development will surely emphasize. So last week, AlphaZero won a 100 games chess marathon against Stockfish.  Not only did AlphaZero win, but it didn’t lose a game at all! It won 28 games and drew 72. The spectacular aspect from a tech perspective is that AlphaZero learned the game in only 4 hours. Continue reading

Azure automation FTW!

Published by:

Azure automation is, in my opinion, one of the heavily underrated offerings in the Microsoft Azure platform. During my time at Microsoft I had the opportunity to work with some great partners on Azure automation projects and also talk about it at the Microsoft Partner Days in Munich. So I thought it might be worth writing a few words about it on my blog and move away from the .NET Core topic. A huge challenge is to keep this as short as possible.

Microsoft Azure Automation provides a way for users to automate the manual, long-running, error-prone, and frequently repeated tasks that are commonly performed in a cloud and enterprise environment. It saves time and increases the reliability of regular administrative tasks and even schedules them to be automatically performed at regular intervals. You can automate processes using runbooks or automate configuration management using Desired State Configuration. I will not give the entire “Intro” talk here :). If you are not familiar at all with this topic, you may check the official Microsoft getting started guide. Continue reading

Deploy a NET Core console application using command line

Published by:

Few days ago I blogged about .NET Standard, .NET Core and .NET framework and I think it might be a goo idea to write something about .NET Core today. .NET Core is an open source, cross platform development framework in the .NET world. What I would like to do today is to show how to deploy a .NET Core console application using command line. This is nothing complicated or particularly useful, but it will help to get a better understanding on what “cross platform” means. I will use Visual Studio Code and the integrated terminal to run the needed commands. Continue reading

.NET Standard, .NET Core and .NET Framework demystified

Published by:

Reading Twitter and several discussion threads on GitHub  or Reddit, I came to the conclusion that there still is a lot of confusion when discussing .NET Standard, .NET Core and .NET Framework. The truth is, .NET Core and .NET Standard are still new and Microsoft also keeps making some changes when releasing different versions that add to the confusion. That’s why I will try to demystify these different components of the .NET world. Before getting into it, I would like to underline that this is my understanding and therefore I might be wrong at some points, but overall I think the overall picture is still helpful for clearing some of the confusion out there.  Continue reading

Some thoughts on leaving Microsoft and the future of this blog

Published by:

As I already announced on LinkedIn, I decided to leave Microsoft starting November 24th. Strangely enough, I didn’t leave Microsoft because I didn’t enjoy the company anymore, but because I stumbled upon a new challenge that I really couldn’t refuse. More than 2 years ago I’ve decided to leave Office 365 behind and to focus more on Cloud Application Development. The solid foundation I had in cloud identity topics helped me a lot, because if you develop an application you pretty sure will also need authentication and authorization and that’s where Azure AD comes in handy. Now, I got the chance to totally shift focus and become a “real” software developer. That’s why I really couldn’t refuse this challenge and am glad to have joined AmdarisContinue reading

ADFS in multi forest environments

Published by:

ADFS in multi forest environments is still a very hot topic based on my day to day experience. Even if I’m concentrating more on cloud application development projects for more than 8 months, I still get a lot of questions from partners, colleagues, customers, IT admins from all around the world regarding this specific scenario. To put this in a little bit more perspective, the questions are usually asked in the context of Azure Active Directory, so the already renowned federated identity scenario. So that’s why I decided to blog about it, hoping to complement the scarce existing documentation.

Before we get started I would like to clarify one thing. Even if I will reference a lot Azure AD, everything I describe here is not restricted to Azure AD as a relying party. In fact, last time I worked on such a scenario, the relying party was AWS. So let’s get started.

The basic scenario is the following: a company has two or more Active Directory forest and one Azure AD. Using Azure AD Connect we can synchronize several forests to the same Azure AD. The question arises on the ADFS design. How many ADFS farms would we need? How would this work? Is this supported? Continue reading

#Build 2017 – some exciting things

Published by:

I just finished watching the #Build 2017 keynote and I am really excited by all the new things that were announced in this occasion. There were so many cool things that at the end I started to forget those mentioned at the beginning. That’s why I thought of writing a //build 2017 keynote summary, to serve more for me remembering all the things that I need to keep up with during the next year.

One of the coolest thing is the new Azure Cosmos DB offering. Azure Cosmos DB is Microsoft’s globally distributed, multi-model database. With the click of a button, Azure Cosmos DB enables you to elastically and independently scale throughput and storage across any number of Azure’s geographic regions. It offers throughput, latency, availability, and consistency guarantees with comprehensive service level agreements (SLAs), something no other database service can offer. What this means is that you have a database where you can store documents, tables, graph data and many more in the same place and use really any DB API to access all the data in nearly real time.

Just to stay in the same database area, the announcement of Azure database for MySql was also a nice surprise. Basically, you get a MySql database as a service, without the need to take care of patching infrastructures and so on.

Further, Microsoft announced at //build 2017 the new Azure IoT Edge, a technology that’s meant to extend “the intelligence — and other benefits — of cloud computing to edge devices.” It’s a cross-platform run time that runs on both Windows and Linux, and it will work on devices that are smaller than a Raspberry Pi. This will solve a lot of problems in IoT scenarios with really small devices, since this new features enables a more straight forward communication between Azure and devices.

Next, the announcement of the new Azure Portal App for iOs and Android, together with the built in full featured Bash shell in the Azure Portal was also a very intriguing announcement. First, the mobile app is not available on Windows 10 mobile devices (I know, there are few of them out there, but still….) and second, the first integrated shell is a Bash shell, not PowerShell (PowerShell will come “some time” in the future). On the other side, this underlines once more the heavy open source approach that Microsoft is showing during last years.

The remote debugging of production web apps using Visual Studio 2017 without any downtime was also a great thing to watch.

Let’s go to the AI part. I was already fairly familiar with Microsoft Cognitive Services, but the announcement of the custom vision API was really exciting. This enables developers to easily train their own vision machine learning models, providing the necessary training data. This really starts to look more and more like democratized AI, which should enable developers to build more and more intelligent applications.

The PowerPoint Translator was also a fairly cool demo, but for me it was not necessarily something new since exactly the same thing was showcased two years ago at the Build conference, but back then it was a Skype extension, called Skype translator. These two are fairly similar.

A final observation: almost all demos were made from MacOS laptops and iPhones.

Watching the //Build 2017 keynote was a very good time investment. I still dream to attend this conference in person at some time 🙂

Testing Azure AD per app MFA and conditional access based on network location

Published by:

Azure AD conditional access and per app MFA is globally available starting today, as announced by Alex Simmons. This feature was in preview for some time, but now, that it is globally available, it can be used in production environments. Since this is a new feature, I played a little bit around with it and I would like to share some insights.

Azure AD per app MFA and conditional access allows administrators to set MFA requirements on applications that are registered in Azure AD. This enables interesting scenarios, like for example requiring MFA for Exchange Online, but not for SharePoint Online, if a request comes from outside the corporate network. In order for this to work, you would have to activate MFA first and define the IP ranges that define your corporate network in CIDR format. You should be able to do this by accessing following URL: reading

Curriculum Vitae Builder, a great Office add-in

Published by:

When I talk to partners or during my speeches at conferences I almost always mention the fact that there is a big market for Office add-ins and that developers should clearly exploit it. Today I stumbled upon a great Office add-in called Curriculum Vitae Builder, developed by Egomnia. And this add-in is really great, especially for graduates or for professionals that seek a new professional challenge. With a lot of different versions of résumé it is often difficult to put together a very strong and appealing curriculum vitae. However, with Curriculum Vitae Builder you surely won’t forget any important information about yourself. Continue reading
