  • Companies are working fast to figure out how to make money from the wealth of data they’re beginning to have about our online friendships
  • Lotus Connections is a little bit screwy when it comes to profile pictures IMHO as they are being forced to be square in Profiles (115×115 pixels). In profiles search results however they are scaled to 55 pixel in width and height is automatic. This post contains code to fix that.

  • The core of any great race starts with your training. And, of course, what you do just prior to your race and then during the event itself will have a tremendous impact on your performance. Spelling out the details of these two areas could fill the pages of Triathlete magazine for the next 10 years, but there are a few steps you can take regardless of the training program you are following right now to help boost your chances of achieving your goals.
  • In the Traveling Salesman Problem, the goal is to find the shortest distance between N different cities. The path that the salesman takes is called a tour. Testing every possibility for an N city tour would be N! math additions. A 30 city tour would have to measure the total distance of be 2.65 X 1032 different tours. Assuming a trillion additions per second, this would take 252,333,390,232,297 years. Adding one more city would cause the time to increase by a factor of 31. Obviously, this is an impossible solution. A genetic algorithm can be used to find a solution is much less time. Although it might not find the best solution, it can find a near perfect solution for a 100 city tour in less than a minute. There are a couple of basic steps to solving the traveling salesman problem using a GA.

Lotus Connections – A profile does not exist for this person

A strange error started occuring in our deployment of Lotus Connections a month or so back. The business card functionality started showing the error "A profile does not exist for this person". It was interesting because you could be sitting on one of the affected users' profiles, initiate the business card popup and still receive this error.

Turns out that if any part of the JSON processing fails, this is the error you get. It may be that a profile was truly not found, or it may be that something invalid was returned. In our case, a field that was included on the business card contained an apostrophe – and the apostrophe was not escaped or URL encoded, so it was terminating a string prematurely. Once I put code in to begin encoding the apostrophe all was fine.

Social Networking – It is all about me

It's really not, but at first it is. I am talking about social networking here. Initially, you joined Facebook and set up your profile and waited. It was about you and what the system could do for you. Then you became a more active contributor and collaboration happened.

Several weeks ago when I was blogging more regularly, I talked about automating affinity -> having the system tell you people you SHOULD know rather than people you may know. Ultimately, this requires you to have a profile in place with enough semantic information in order to generate a machine interpretable profile. There are a few algorithms / semantic languages forming to assist in determining affinity. FOAF, APML and SIOC all seek to provide a means for determing things or people you might be interested in.

One of the neat features we're rolling out in the release of our social networking platform at McKesson is the integration of social search results with traditional search results from our intranet. When a user performs a search, in addition to finding regular content, they will be presented with "Related People". For the searcher, we've implemented discoverability simply by hooking into their search request. For those who fill out their profiles, we have containers in place that allows them to drop information into containers (about me, certifications, customers, etc) that are then indexed appropriately and served up based matching search terms. This looks like a recipe for successful matching of expertise & interests – we'll see how it turns out over the next several months.
