With IBM, Google, and Microsoft pouring funding into the research of quantum computing, it's really starting to look like we are going to see the benefits in the next 5 - 10 years. Google may be just weeks from announcing they reached the quantum supremacy milestone and IBM may not be far behind either.  Today, I wanted to share my thoughts on how quantum computing may affect cryptography as we know it. Effects on cryptography When we talk about the basic cryptography used for things like TLS when you access your bank's website, the premise behind securing your data is surprisingly simple. The certificate uses a public key which is really just a large number that's the result of multiplying two prime numbers together.  This key has a size typically between 256 bits and 2048 bits. It's quite a large number.  To find the two factors via brute force, in today's classica... (more)

Start Learning About Quantum Computing | @CloudExpo #AI #ML #DX #Cloud

Quantum Computing is becoming quite the hot topic lately.  With research being done by Google, IBM, Microsoft, universities, and a number of other players, it’s looking this is really going to happen.  In fact, Google may just be weeks away from announcing the Quantum Supremacy milestone.  If you aren’t familiar with the concept of Quantum Supremacy yet, it’s basically the point where a quantum computer can complete a computation in a short time where a classical computer can’t complete it at all.  This is a big deal.  While there are some simple quantum computers out there right...

Six considerations for running a multi-tenant mobile app using Azure App Service

With the launch of HappenZap, I now have two multi-tenant mobile app platforms running on Azure App Service.  When it comes to the backend services for mobile apps, Azure App Service really isn’t used that much though.  In fact, in the 2017 Ionic Developer Survey, Azure only accounted for 10% of the users using it as a server side platform (behind Heroku, Digital Ocean, and Amazon ECS).  For authentication, it ranked even lower at only 2.9% of the survey results.  For Push Notifications, it wasn’t even on the list.  However, for both my platforms, I have chosen to use it and ha...

Calling the Enterprise Search Web Service from Silverlight 3

I needed to do a quick proof of concept of displaying search results in Silverlight recently and it actually proved easier than I thought it was going to be.  I tried this once before in a beta version of Silverlight 2 and it was much more difficult at the time.  I was able to easily add the reference to the search web service but the proxy was filled with classes that were not supported in the Silverlight .NET Framework.  This time I was relieved to find that it was much simpler.  I’ve written many applications to query using the web service, so the first thing I thought of wa...

Using CAML To Deploy A Lookup Column Via Feature

This week, I needed to deploy lookup columns to some of my lists and as usual I wanted to avoid writing code at all costs.   As some of you may know, Kyle Kelin and I debate this topic often as he prefers a code approach.  I figured it had to be possible with CAML, but many claimed it was not even possible.  A few approaches showed up out there involving using code to modify the elements.xml file with your GUID, but that just wasn’t going to cut it for me.  One popular post on the topic by Josh Gaffey, started me in the right direction, but there were a few hurdles I ran into as ...
