First, please unplug your computer...

| 3 Comments
I spend a lot of each day answering support questions.  Many of the questions we get are really good questions.  Some present us with difficult investigations that can take hours or even days to understand and solve.  A few remind me of a story I heard once from someone I used to work with.

This guy used to provide support for some sophisticated laboratory equipment.  Users would call in with the usual assortment of problems and he would help them solve whatever problems they were having.

Occasionally, someone would call in and say that their equipment was simply not working.  No matter what they did, the machine would not respond in any way.  When asked the obvious question, "Is the machine plugged in to a wall outlet?" the answer was always "Of course it is plugged in."  But sometimes, after hours of further investigation, it turned out that the machine was, in fact, not plugged in at all.

So, he came up with a different way to ask the question.  He would say, "To solve this problem, I need you to unplug the machine, leave it unplugged for 15 seconds, and then plug it back in."  As the person on the other end of the phone carefully followed the power cord back to a wall outlet, they could often be heard gasping as they discovered that the machine was actually not plugged in.  After plugging it in, the machine started responding correctly.  This approach saved many hours of investigation based on the assumption that the machine was actually plugged in.

Now, I am not saying that we get any support requests like this.  I am just saying that sometimes, some random association makes me think of this story.

Display of Sync Details

| 2 Comments
We introduced support for synchronized libraries in Sente 6 about a year ago and, in general, we are pleased with how well the system is working.  Most users have had not problems turning sync on and creating synchronized copies for use on other computers or iPads.  (The recent introduction of Sente Viewer for iPad has significantly increased the load on our servers, but that is another issue; one we are happy to have!)

To help everyone better understand what is happening with sync, and to help track down any problems that might occur, we have modified both desktop Sente and Sente for iPad to make more information about sync status available to the user.  Specifically, Sente now shows:

  • Library Identifier.  This is a short alphanumeric code that identifies the synchronized library as found on our server.  Every copy of a particular library will display the same value for this identifier.  If you have two libraries that are not syncing, the first thing to check is that the library identifier is the same for both copies.  (This value is set at library creation, and never changes.)
  • Change Number.  Every time you edit a reference in any copy of a synchronized library the change is sent up to the sync server, and then retrieved by all other copies.  These changes are numbered sequentially, and each copy of the library knows the number of the change that it last executed. If two libraries show the same Change Number, they should be exactly in sync.  (Obviously, if you ever encounter differences in the data between two copies of a library with the same Library Identifier and Change Number, we want to hear about it.)
Most users will never need this information and can just ignore it.  But if you have any question about whether two (or more) copies of a library are in sync, a quick look at these values in each copy will give you the answer.  

(The update to Sente Viewer for iPad that displays this information has been submitted to the app store, and should be available in the next week or so.  The update to desktop Sente is available now.)

Sente Viewer for iPad is Now Available

| 21 Comments
As many of you will have noticed from the comments on the previous post, this app is now available in the App Store.  Sente Viewer is read-only, so don't expect to find PDF annotation, note taking, targeted browsing, or even reference editing.  All these features are coming in the full app, but they are not present in the (FREE) viewer app.

We hope you find it useful and a good indication of things to come!
