Solar Numbers Updated

The solar energy production numbers have been updated with the production on June. Not bad, not spectacularly good.

You are using AD group names to define the users of specific permission groups in SharePoint, right? After all, those groups are already managed centrally somewhere in your organisation, and you don’t want to duplicate that work…

You have this page displaying list items, but some of your users may see just a bit more than others, and those users are defined in a separate group. So you’re trying to determine whether a user belongs to a specific (SharePoint) user group, using a bit of JavaScript. Good idea: that’s what jQuery and SPServices are for, right?

Unfortunately, the following code construct will not work for users in those AD groups:

  $().SPServices(
    {
      operation: "GetGroupCollectionFromUser",
      userLoginName: $().SPServices.SPGetCurrentUser(),
      async: false,
      completefunc: function(xData, Status) {
        if ( $( xData.responseXML ).find( "Group[Name='xxxxxxxx']").length == 1 ) {
          // Try something worthwhile here…
        }
      }
    }
  );

Why does it not work? Because SharePoint manages its own “user accounts”, and while the Permissions of the users in the AD groups will be recognised and applied correctly for standard SharePoint features, the SPServices call for such a user will result in a “User unknown” message. The user has not been defined in the SharePoint user database, and thus there is no way to get to the user’s profile.

To solve your problem, divide your page into separate WebParts, each using the appropriate Audiences. One webpart shows the content for the special users only, and the other has what is needed for the rest but excludes the special users. Simple!

If you really need to know whether a user belongs to a non-SharePoint user group, then you’ll have to write code that consults AD rather than the SharePoint user data – depending on the configuration of your AD that may be possible through web services (or not). Probably too much work, when there are easier solutions around. Better go with the SharePoint flow!

I have just spent the best part of an hour updating a series of older posts on this blog, deleting category “Software and Development” from them and adding “Software Development” at the same time-  for the sake of consistency, right? I have seen it happen on other sites: all updated posts are included again in the RSS feed, causing a bit of scratching when you read stuff that’s a decade old (yup, that can happen on this blog). I don’t think it did, but if it happened on this WordPress site, then I apologise for the “spam”!

Fargo is an interesting piece of technology, especially for people who like outlines and blogs. Chris Dadswell wrote a complete instruction manual on setting up your own, self-hosted static Fargo blog: “How-To: Fargo Self-Hosted Publishing“.

But what I like most about his post is the footer, quoting my favourite poet Frank Zappa: “Moving to Montana soon, gonna be a dental floss tycoon”… Thumbs up, Chris!

The BMW K-series of the 1980’s and 1990’s were not exactly loved for their looks – the surname of the original K-series, “the Flying Brick”, is a clear indication of that fact. However, it is possible to turn such a brick into a beauty, as evidenced by this Estonian handiwork:

Read all about it on the Pipeburn website: “BMW K75 by Renard Speed Shop“. And I’m not hiding the fact thatI would love to ride this bike, if only to feel to what extent it is different from the K75 I owned for so many years.

Not yet seven years old, and already the subject of an historical overview: “The history of Android. Follow the endless iterations from Android 0.5 to Android 4.4” (on Ars Technica).

There’s “An illustrated history of the Android interface” as well. What all this mainly illustrates, is the speed of change in the software world – even Android 2.0 (late 2009) looks quite antiquated!

Have A Laugh With The CIA

Ars Technica writes: “It’s not often you’ll see the spy agency having a sense of humor.

Well, that gives us at least one opportunity in many years to laugh with what the official intelligence instances are doing…

The Belgian “Centre for Historical Research and Documentation on War and Contemporary Society” (CEGESOMA) has published a website containing not just an extensive inventory of both the censored and the clandestine press during both World Wars of the 20th century, but also a digitised copy of all (?) the available issues.

As a historian, I can only applaud the availability of such source material. Now anyone can have fun while browsing those issues at random and be surprised with their tone, or with the information contained in them.

In Memoriam: Rebecca Alison Meyer

I don’t know Eric Meyer in person, nor do I know his family. But I have been reading his blog for many years, and used some of his tools. So in a sense, I do know Eric Meyer. That’s why, even just in a small way, I share his loss. His pain, and that of his family, must be gigantic. I hope they will find the strength to never forget the joy and laughter and beauty that Rebecca injected into their lives (and vice-versa), rather than what she’ll never be able to do… May the force be with you, Kathryn and Eric and Carolyn and Joshua.

The Force Of Yellow

The weather is fine here Belgium these days; some will even say it is already too warm (we seem to be hitting 30° Celsius and more). Still, it’s a good time to ride your motorcycle – and at the same time remember that such temperatures aren’t required to have a great time on two wheels. Just check out this picture…

From Petapixel:

Human memory has a tendency to slip, and critical judgment to fade, with the years and with changes in life-style and circumstance. But the camera, just as it seized the grim realities of that time, brings the stark facts of seven years ago before our eyes without the need for the slightest embellishment. (Yosuke Yamahata)

The update of the solar energy production numbers of our panels gives me  a good reason to display another sunny photograph ;-)
