Here’s a first for NotesIn9. Not only are we getting yet another brand new contributor that I’ve wanted to get on the show since LAST Lotusphere. And not only is this person from IBM which is just really cool to see on Ni9. And not only is this person the lead of my favorite software product – Domino Designer. But….
It’s his BIRTHDAY TODAY!!!!
So a big happy birthday and NotesIn9 welcome to Dan O’Connor!! Dan is a great guy that I had the pleasure of working with a bit last year as I helped to put together the 2nd XPages Cheatsheet that was focused on Social Tools.
In this show Dan first talks about the Social Enabler and what it is and means. Then he goes into a demo on how you might go about connecting your xpages application to something like DropBox or Connections or Twitter.
NotesIn9 welcomes long time speaker but first time contributor Paul Calhoun to the show.
Paul is an amazing teacher and he’ll show us how to use the Dynamic View Control. This is a control from the XPages Extension Library that can basically auto-create views for you. Say you have 15 views in your application. Previously you might have to make 15 xpages or custom controls to show them all. Well no longer! The Dynamic View Panel Control can make the views automatically for you. This saves you lots of time! Hmmm Sounds like an infommercial really.
But hold on there’s more!! Paul will also show you how you can individually customize these automatically built views. That’s right friends! Don’t wait! Click on the video now to be amazed!
UPDATE: Per Lausten pointed me to this StackOver Flow article which discussed the Customizer Bean. Be sure not to miss the links to work done by Jesse Gallagher (who I’m trying to get on NotesIn9 himself). Jesse’s project is meant to try and make the dynamic panels replicate the original views more closely.
In this show Niklas Heidloff comes back to take another look at a technique used in the CollaborationToday.info website. He will show how they keep a count of what articles people are clicking on.
Just wanted to say another big thanks to Niklas for contributing these videos to NotesIn9 and to the team from OpenNTF.org for creating the application in the first place.
This is part 2 of the Making of CollaborationToday.info. This is is an aggregation website of relevant news and articles for IBM Collaboration Solutions. In this show Niklas Heidloff shows us how they speed up the site with data caching techniques. In order to maximize performance this site caches view data into memory by using a Java bean. This means that in can render pages from memory rather then having to hit a view index on disc all the time.
Don’t miss these 2 recent NotesIn9’s: Part 1 of Making CollaborationToday. What are Java Beans?
The database might require the Ext. Library because it contains a mobile demo I’ve not screencasted yet. the Java Bean stuff does not use anything from the Ext. Library.
In this show I attempt to tackle the “forbidden topic”. Yep. Java. Me talk about Java. It’s unexpected. I know. This show is an expanded version of parts of a presentation that I did at MWLug.
I first talk about some of the tools available to the XPages developer and when you might want or not want to use some.
Then I get into the meat of the show – Java Beans. I try and explain exactly what they are and show what they look like. I talk about managed and “unmanaged” beans and go through what they look like and a little bit on how they can be used.
This is a “getting to know them” type show. Not an indepth getting started on building them. I didn’t intend to do this show quite yet but I’m getting some great contributions as part of the Drive to 99 Event that are starting to talk about Java beans so I wanted to get this little intro out.
There’s lots more Java Beans stuff coming. If you can’t wait Jeremy Hodge did 3 shows for NotesIn9 that are highly recommended. I’ll probably be doing my attempt and an indepth intro to Java in the near future as well.
If you have any questions please ask.
P.S. This show is about 36 minutes and I got it in 1 take! BOO YAY!! 🙂
In this show John Jardin comes back on to expand on his part 1 episode. He’ll demonstrate more XPages and Relational Data integration and show you how to make things a little more flexible.
In this show Dr. Mark Roden from Xomino.com returns to NotesIn9 to show us how to get started with adding a typical jQuery Plugin to our XPages applications. There are probably thousands of plugins available for jQuery and they can be used to enhance your website.
I also talk about the current open nomination period for OpenNTF.org elections. If you have time and desire please consider getting involved in OpenNTF. It’s a worthwhile resource.
In this episode Niklas Heldloff from IBM and OpenNTF.org comes on the show to talk about the brand new community site: CollaborationToday.info.
Niklas was one of the team that built this site. Â This is the first part of a series of videos that detail what the site is and how various pieces were built. Â This video focuses on what features the site contains and how you might go about setting up your own version when it becomes available.
Big thanks to the team that created this site. Â I think this is a huge contribition to the community, not only the site itself, but the code – which should make it to OpenNTF in a couple weeks or so. Â I think this will be an app that you’ll want to pick apart to see how it was built.
Also I want to thank Niklas for taking the time to make the video and joining me on the “Drive to 99”!!!
UPDATE: I made a mistake on the Slide for Niklas’s website. I typed in http://heidloff.ntf when it should be http://heidloff.net. Sorry about that!
This episode marks an early start to the NotesIn9: Drive to 99 event.
I recently spoke at the MWLug conference. Â This show is the first part of what might be 4-5 parts of that presentation turned into a screencast.
In this show I talk about Domino Designer and source control first. Â These are brief reviews of some longer shows I have done. Â Though I talk a little more indepth about source control “Branching” which I’ve not done before. Â I then talk about some tools that you need to have in your designers toolbox.
Hope you like it as our “Drive to 99” starts heading to the highway!
UPDATE: Since I stumbled in the show on what “Xmx” and “Xms” are I was excited to get some feedback from Dan O’Connor of IBM.
I saw you were a little unsure about the xmx and xms variables/args :-).
xmx is the maximum heap size, it is a variable that is passed to the JVM on startup, and is the maximum size the JVM will allow its heap to expand to.
xms is the minimum heap size, and while you might think setting this to a really low number can do ‘no harm’, it is actually advisable to set it to a ‘reasonable’ number, as the JVM is usually optimized to initialize to the minimum heap size, and if this size is too small for the number of objects needed to initialize the program (in this case Designer), as a result the JVM has to keep cycling until the optimal heap size is reached, which can have a performance impact.
Dan also suggests referring to the book “XPages Portable Command Guide”. Â There’s a section in there that starts around page 86 and goes into more detail on what the Java heap is and how it affects performance. Â While the book is geared for the server, the same principles apply to the client as well. Â I hope to review those pages and go into that in a little more details in a future NotesIn9.
