What’s New

NEW Support for RokBox 2.0, use under Rendering “RokBox 2”, instead of “RokBox”

NOTE: If you are upgrading from RokBox 1 and you are using the old RokBox syntax, such as {rokbox} or <a rel="rokbox" .., you can enable the Backward Compatibility from both the System and Content plug-in. Be aware that the Backward compatibility can dramatically slow down the loading of your site. It is highly suggested to convert the old syntax into the new one. Starting from cedphotofeed 2.6.3 you can use the Rendering “RokBox 2” and switch off the backward compatibility.

NEW A new settings in the administrator panel “Force”. This setting is optional, default value is auto detect- If you use custom URL for your hosting library (like visuals.waltercedric.com instead of www.smugmug.com), you may want to force the library instead of letting cedPhotoFeed auto detect the right host based on URL. You can either set "Force" = "Yes" in administrator panel system wide or add this optional settings now in every mambot. Here is a axample of a custom URL that use SmugMug:

{rss uri=http://www.darbym.com/hack/feed.mg?Type=nicknameRecentPhotos&Data=DarbyM&format=rss200 limit=3 force=Smugmug}

Concerning the size of pictures displayed when using Picasa

Concerning the size of pictures displayed when using Picasa, the max picture size returned by the RSS feed is height="265px" and width="512px", embedded thumbnails being of size

height="38px" width="72px"
height="75px" width="144px"
height="149px" width="288px”

It is not in any way a limitation of cedPhotoFeed!

HP calculator museum: HP35s Scientific Calculator, 2003

The HP 35s is Hewlett-Packard’s top-of-the-line pocket scientific calculator, celebrating the 35th anniversary of the HP 35, the first pocket scientific calculator, which was introduced in 1972. It is the successor to the 33s and the famous 32SII, among others.

Over the 33s, the 35s adds enhanced complex number support, better programmability, EOS instead of AOS-style input in algebraic mode, and support for vectors, among other improvements. Essentially, it appears to take a 33s, give it a more traditional appearance, and add some of the most important features from the 15C and 42S.

HP calculator museum: HP39+ student graphic calculator, 2003

HP-39g series calculators are the successors of HP-38G.

There are five calculators in the 39 series of HP graphing calculators. These calculators have algebraic entry modes, and can perform numeric analysis together with varying degrees of symbolic calculation. All calculators in this series are aimed at high school level students and are characterised by their ability to download (via cable or infra-red) APLETs or E-lessons. These are programs of varying complexity which are generally intended to be used in the classroom to enhance the learning of mathematics by the graphical and/or numerical exploration of concepts. Some hundreds of these can be found on various websites

Basic characteristics

CPU: 75 MHz ARM9
Communication: USB port (using the Kermit or XModem protocols), IrDA (infrared).
Memory: 256 KB
Power: 3*AAA as main power, CR2032 for memory backup
Screen resolution: 131×64 pixels
Does not come with a hard cover
Limited symbolic equation functionality.

Note: Although an ARM processor is used in this model, the operating system is substantially the same as that of the 39G, with the Saturn chip being emulated on the ARM at a higher speed than was possible for the 39G. The CAS component of the HP-40G’s operating system appears to have been totally removed, rather than simply being hidden at start-up.

Apache POI contribution patches

The Apache POI Project’s mission is to create and maintain #Java APIs for manipulating various file formats based upon the Office Open XML standards (OOXML) and Microsoft’s OLE 2 Compound Document format (OLE2). In short, you can read and write MS Excel files using #Java. In addition, you can read and write MS Word and MS PowerPoint files using #Java. Apache POI is your #Java Excel solution (for Excel 97-2008). We have a complete API for porting other OOXML and OLE2 formats and welcome others to participate.
