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...

How to: Create a BCS Profile Page in SharePoint 2010

I was working on updating my Search demo for #spshou and my BCS search results were really ugly.  I didn’t have a default action specified on my search results, nor did I have a profile page, so instead the search results would give me the BDC protocol URL which is not usable by an end user.  In MOSS 2007, if you did not create a default action, it would automatically create a profile page for you.  In SharePoint 2010, this is not the case.  It’s pretty easy but there are a few steps involved. Start by opening SharePoint Designer and open your external content type in question. ... (more)

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 ...

COMException (0x80004005): Cannot complete this action after installing Service Pack 2

It’s a known fact that MOSS 2007 Service Pack 2 hates me.  Today, I was excited when I upgraded a server to SP2 and the configuration wizard didn’t fail.  I was even more excited to see that my SSP and Central Administration still worked after the upgrade as well.  Unfortunately, when I hit my main web application, I got a yellow screen with the following error. COMException (0x80004005): Cannot complete this action.   Please try again.]    Microsoft.SharePoint.Library.SPRequestInternalClass.GetFileAndMetaInfo(String bstrUrl, Byte bPageView, Byte bPageMode, Byte bGetBuildDepend...
