Pierre-Eric Rocks

A while back I put out a blog entry about some bounty work with OpenOffice. I was contacted my new favorite hacker, and his name is Pierre-Eric. We built a machine with which to quickly compile OpenOffice, and he immediately started creating patches. We have been impressed with his professionalism, and his energetic approach to open source software. His first two patches were accepted by Sun and look to be merged into OOo 3.2.

The first patch creates a 2x2 picture layout for Impress:



The second creates a 3x2 picture layout for Impress.



He is currently working on a patch to add a "Sentence Case" option to Writer. We have a few more projects waiting in the wings, and are looking forward to continued bounty work.

Shuttle

Shuttles have been going up almost 30 years, and it's still amazing to me. It's even better now that I live in Florida and can see it in person!

Help With XWD

Since we went live on the new desktop we have had a nagging issue with screendumps. From time to time the "import" command once activated would log you off the server and return you to the XDM chooser. I have never been able to replicate it reliably for debugging until today. I had always suspect it was a crash of gnome-session or the parent dbus process. Turns out it's a crash of X on the thin clients, which makes it a lot harder to patch and fix. We are not ready at this point to push out a new build to our 550 devices.

So I have been looking at our good old friend, xwd. It would perfectly meet my needs, and doesn't crash in the same place as import. The problem is there seems to be an endian issue when using Compiz. The shot below shows what is dumped when Compiz is active. Ideas and technical information is appreciated. I don't mind using convert on a second pass to revert the original colors, but am not sure what exactly is wrong with the image.

ICS Based Document History Goes Live

A few months ago, I built a little prototype script that generated .ics files from .recently-used files generated by OpenOffice. Very frequently users know when they edited a document, but can't remember what they named it. The feedback was positive, so I made the script a bit more robust and submitted it to the cron for all of our employees. Some users were creating .recently-used.xbel files because they are making use of the GTK file picker, and the script was updated to take that into account as well. If you have a server and multiple users, the code is here . It's a bit hard coded for our environment, but should be a good start.

In the shot below, users are able to see the date and time that they touched files in OpenOffice; from within Evolution.

Best Things Are Free

I am always one to try new things, and certainly enjoy saving money. I have a NetFlix account that I use to rent Blu-Ray movies, and for a few months they have been promoting their streaming movies. A few weeks ago I looked at it, and it turned out that this feature was available in my current plan. I have a 768K DSL modem at home, and didn't expect it to work well. I was pleasantly surprised that it actually wasn't too bad on my Mac laptop. I had been paying 25 dollars a month for HBO/Cinemax; which I found I used mostly to watch older movies. I'm not one to watch movies on a computer, so I checked into the Roku Netflix box. It's a 100 dollar onetime charge and then movie playback is included in your Netflix account. So I turned off HBO/Cinemax and should now have a 4 month payback.

The box arrived and was amazingly easy to install. You plug in the power, and connect it to your TV and are basically done. A screen came up and found my SSID, asked for the password and downloaded the latest firmware. The Roku rebooted and the menu came up in HD/720p over HDMI. You add movies to your Instant Queue from a computer, and within 1-2 seconds they appear on your TV. With 768K the movies certainly are not Blu-Ray or even DVD quality, but they aren't much worse than the digital signals I was getting from the cable company.

All in all for me, it's working very well and just wanted to pass along the information.

Bounty, Contact Me

Please contact me email drichard at largo.com or dave_largo on the IRC if you might be interested in a minor bounty project. Apparently the Layout Slides in OpenOffice Impress are hard coded into the source. An example of adding another slide is displayed on this issue. We would like to add 2 more slides. One that is a 2x2 grid to hold photos, and the other which is 3x2. I have circled them in the mockup below. I would create the issue on openoffice.org, you would attach the patch. It would be my job to get it accepted and merged.

Keep The Changes Coming

One if the hardest things about working with users is translating theircomplaints about using open source software into something actionable. One of the things that we have heard before is that people sometimes didn't like how the charts work in OpenOffice. Chart2 helped that greatly. I'm now getting very positive feedback concerning the anti-aliasing found in OOo 3.1. (shot below: 3.0 vs 3.1). If you guys keep sending these things to those of us that implement software, it becomes easier and easier to deploy Linux and OpenOffice! Thanks to all involved.

Evolution Pleasantness

I feel like it would be easy to get into a rut of using a blog to vent about problems. I wanted to send out some kudos. I'm involved with the beta program for prepping Evolution 2.24 for use with Novell Groupwise. We are making progress and things are looking better and better every day. I look forward to completing this project and getting the features moved out to our users. I also am excited at the prospect of this being available for corporate customers who are considering Linux. Email, word processing and browsing are the core functions of any business/Government desktop and they are getting better and better all the time.

Quick Project Updates: Getting back into the pulse questions I raised in my last blog; testing Firefox 3.1 and all plugins, testing Openoffice 3.1, testing Groupwise 8, looking at thin client updates. ToDo List: Avant code re-sync, QA HP 5735 thin client testing, check out Nomad over low bandwidth on thin clients, re-sync with latest Compiz.

Pulse Audio & OpenSuse 11.1

I'm not going to jump on the Pulse Audio bashing bandwagon, but have a real question for those with knowledge of the current status on OS 11.1

Our 550 thin clients all havePulse version 0.9.6 running as a daemon. I am in the process of building an OS 11.1 server to house Firefox 3.X for all employees. Youtube is one of my QA sites. When I play a flash video from that site, it starts fine and then after about 20 seconds starts to get choppy and then finally crashes the daemon on the thin clients. I was told on #pulseaudio that some timing patches might need to be merged, so I updated all pulse packages from the "Next" repository to the following release:

pulseaudio-0.9.14-43.7
pulseaudio-esound-compat-0.9.14-43.7
pulseaudio-lang-0.9.14-43.7
(all pulse packages were also updated to the same level).

It's still doing the same thing.

So unless there are some patches waiting to be merged, I have two bad prospects. 1) Trying to compile and install 0.9.14 for the thin clients (Debian Woody) -or- 2) trying to back out pulseaudio packages on OS 11.1 and recompiling version 0.9.6.

Anyone with more knowledge in this area have any thoughts?

Update: I just wanted to clarify that I don't think anything is wrong with OS 11.1. I believe the issue to be related to a mismatch of Pulse versions between the OS 11.1 server and the thin client. On OS 11.1, all libraries are the same version and things probably work fine. I also should have mentioned that I'm attempting to use Flash 10.

Merging Document Management And A Wiki

Recently we had a technology planning meeting to talk about future projects that will be coming in the next 3-4 years. I expressed my views strongly that unless we shake loose of our culture of paper, that IT would collapse under the weight of printer support. Up to this point, every software package that we have purchased has produced more paper than ever before. Anyone that supports printers know; they are a horrible amount of work to keep running. Users sometimes print documents to read them, and then throw it away. Or they take it back to their desk, stuff it into a folder and there it sits for 10 years.

This is very much a work in progress, but we have been experimenting with moving some of our work flow and document management into a Wiki. I have been telling people here how nice it was to see the GNOME wiki being used when I visited the Boston UI Summit. Notes were entered in realtime, documents were attached, thoughts were shared, white boards were photographed and loaded into pages.

After reviewing some of the Wikis, we picked MoinMoin. It not having a database backend was attractive to us, and the directory structure is very elegant. No flames please on this selection, for us it's a good fit at this time. :) The most important aspect of this test is the flow and not the software.

The image below shows our prototype plan on entering data. Project pages are created, and then meeting notes are recorded and linked into their corresponding project page. OpenOffice + OpenProj documents are uploaded right into the Wiki.



We have talked about buying some inexpensive netPCs for entry of information during meetings, and also have talked about setting up Kiosk style thin clients in meeting rooms that would allow meeting notes to be created immediately. This also would allow demonstrations and slides to be put into the meeting page *before* the meeting, and displayed to the rest of the attendees. It really promotes a collaborative work environment.

As part of our brainstorming, I created some mockups to demonstrate possible future uses of the Wiki. In theory, we could try and load most City documents into the Wiki; allowing users to create documents and actually store them has been a failure ever since the start of computers. No one knows where they are saving things, or how folders should be configured and set up. Perhaps an emerging perspective is that they *shouldn't* have to make those decisions. It's to the greater good of our City that in the future, documents are easier to find.

In this first mockup, I have built an idea of how Nautilus could interact with a Wiki. The Wiki would appear to just be a file system, and the document would load into the appropriate software package. When the user saves it, it would simply go right back into the same Wiki project page.



In the second mockup, I have added a button in Evolution so that when a meeting is scheduled, a corresponding page would be created in the Wiki. The attendees would then receive a message with the link and they could immediately begin adding notes and presentation documents.



I'm not sure of the exact directly that we will be moving, but it's great to see movement away from paper, and the inefficiencies of all meeting attendees taking their own notes.

Firefox 3, Leakish And CPU Heavy?

We are still using Firefox 2.0 organizationally and it's very stable. We still have some sites that are not certified for 3.X, which I am monitoring closely. Like any forward thinking Admin, I have been running 3.0 and the 3.1 betas. I have found them to render faster, and they seem to scroll faster; however it seems to have come at great expense. CPU and memory usage is substantially higher. Can anyone else confirm this? I remember there was great debate concerning file handles and sqlite databases. Are these issues resolved? Right now, Firefox seems like it will be hard for me to scale to hundreds of people.

Here is a snapshot of my session on the server, with moderate usage for a few hours:

Webcals, Summit & Remote Evolution

Things around here have been busy. I have been QAing and testing Evolution 2.24 and its interaction with Groupwise heavily. We are nearly to a milestone where I can increase the pilot/beta and add more people. I also have been installing a MoinMoin Wiki instance for use by City employees. Right now IT is testing it and trying to create some work flow suggestions, and it looks excellent. I will be devoting an entire blog entry to our goals and ideas.

Intranet Webcals

Our internal use of Webcal files has exploded over the last few years, so I have been writing a new GUI to make it easier for users to add sources to Evolution. We have a lot of information stored in databases that is appropriate for people to view on their calendars. Examples of this are employee birthdays, hire dates, anniversaries and so on. So we create .ics files of this type of information and drop it into an internal web server. That makes them available for all employees. Evolution has the ability to add webcals from the command line, so the GUI passes the webcal:// on the command line and it appears right inside their running Evolution session. All they have to do is pick a calendar color. The current state of the GUI is below:



Summit 2009

I have gotten approval to announce the availability of our facility to conduct the 2009 Summit on our premises if there is interest. I know that Boston is the tradition, so I'm just making a humble offer that it can be held at our location if you wish. We have a building that is used for training and emergency operations, and we could conduct the hacking in that facility. The one thing that we could offer is real GNOME users for focus groups and study of new features. We are a short drive from the Tampa (TPA) airport on the Gulf of Mexico. Hit me up on the IRC if this seems like a fit for the community.

Remote Evolution & Miguel

Miguel posted a blog about wanting to gain access to his Evolution while traveling. That exact product existed, was purchased and buried by SCO and now is owned by Sun. Tarantella let us run Xwindows applications 10 years ago, and was one of those great ideas that came out at the wrong time. During that period, people were still excited about client/server computing and how many Ghz you had at your desktop to care about centralizing applications. We ran Tarantella on SCO and Linux and it worked *great* for us. All you did was lay it down in your Apache web server, and point it to your applications and they immediately worked in a browser. In the pre-Evolution-1.0 days I even ran Evolution in this manner. You would log in from any browser, and it started a Java applet, and you would see the gray/white X checker boxes for a split second and your X application would immediately open. No plugins to add to the browser, no client side software. I found this old picture describing how it worked. It's too bad these types of products haven't become more commonplace.

Evolution, OpenOffice 3 And Screen Dumps

I have been busy the last few weeks QAing software for deployment. OpenOffice 3.0 is running well, and has been pushed to our beta testers and they are pleased with how it works. One interesting development in regards to OpenOffice is how much the native Mac port is helping with user perceptions. Even though we don't run it here, an ever increasing number of people are buying OS X computers for their homes. They *love* how well the Mac port turned out and use if for their personal use. This is leading to greater acceptance at the City.

OpenOffice 3.0 goes live on Monday December 1st for our 700+ employees. I wanted a greater level of notification of new features, so I wrote a quick little dialog that opens once immediately before going into the license acceptance screen in OpenOffice (please, please allow admins to accept this license once in the future!). Here is what they will see:



Prepping Evolution 2.24 for deployment has been taking a good amount of time. Much of the "under the hood" code had changed in the last few years, and needed to be tested with the Groupwise backend. My friends in India are knocking out the issues and we are getting closer to reaching a milestone, and working in some much needed calendaring features. Milan cooked up a patch that displays the status of whether people have accepted their meeting requests (shot below) in the tooltip. This allows you to hover your mouse and see if people have declined.



So here is a shot of how Evolution 2.24 and OpenOffice 3.0 will look to the users, coming along very nicely.



Some have been interested in modifications that I make to the standard GNOME desktop. By default, (print) does a screen dump of the whole screen. (alt)(print) allows you to dump just one window. Two other things were happening and required a third option. 1) Some users wanted to be able to take shots of pulldown menus actively in use; 2) Some MS Windows applications running over Citrix/RDP have a canvas which shifts when focus is removed from the window via mouse click or keystroke. So, I globally added (ctrl)(print) which gives them a notify-send popup and alerts them that a screenshot will occur in 10 seconds. They can then position their software was desired and the snapshot is taken.

I have been working on a Wiki/document management/GNOME integration project and will blog about it soon. It's still being discussed and designed at a very initial level, but coming along nicely.

Evolution Testing + Compiz Cube Caps

This last week, I have been busy doing QA work on Evolution 2.24 with the Groupwise backend and submitting all of the issues to Novell. Sankar shipped me a patch late yesterday that allows me to widen my beta testing to more employees. Looks like we will be merging in a lot more calendar functionality which will be greatly appreciated by our users. Each upgrade gets us closer and closer to feature parity to the Groupwise client, which is excellent.

When I was teaching Compiz classes to other employees it was an often requested feature to put other images on th top of the cube caps. This is another example of something too hard for most users with the ccsm interface because it assumes:

- They know what size to create the image
- They know what file format to create, and don't just change the file extension
- They know how to work with transparent layers in GIMP
- They know where to save the file.
- They know where to find the file later.
- They know how to give it permissions that other users can use as well
- They know not to delete it, because it's already been "attached" (ala email).

I went through and generated 10 pre-defined caps with color matched sky domes and then created a very simple custom GUI. All they have to do is push a button and click [ OK] and everything is taken care of for them. 4 of our departments have their logos, and it's little things like this that generate excitement about using Linux.

Evolution Canvas Love?

In the last few weeks major projects that were consuming time have been completed. The new desktop servers have gone live and it's time to move on other projects. OpenOffice 3.0 is out and it has been installed on our server for beta testing by some of our power users. There are tons of features that need to be QA'd before it is moved "live" and that's going to take several weeks.

I also have started doing a lot of work on testing modern Evolution with the GroupWise backend. Version 2.6 (+ backports) is currently in production on SLED 10 and now it's time to upgrade. Lots of the internals of the new version have changed, and I have started putting in bug reports.

Features are an important part of Evolution and the users will be happy with what is coming. However, I can't help but think we can improve the look of the calendar. A new look widget was added a while back, but I'd love to push live something with a bit more of a dramatic look. Yes, part of success of a project is bling in the right places. Unfortunately this type of hacking is beyond my skills.

Here is how Evolution currently looks when displaying the calendars of two users:



It's functional and works, but in my view is lacking the last little bling kick that provide user excitement. In reviewing other products, I found the screenshot below. If we could land something like this in Evolution, I know it would be received well.



Here is what I like about this look:
- Black/White colors for the calendar hash marks, very clean and paper like
- Glass like event UI makes it appear modern and it seems to have depth
- Overlapping colors (which probably should be an option) gives a visual cue of conflicts.

Here is a mockup:



Email is such a critical part of the desktop, and functional and UI improvements make my life so much easier. Chen, maybe this could be finished by the time I get up tomorrow? :)

Fun Time In Boston And Thanks

I just got back to Florida after spending a few days at the UI Hackfest in Boston. It was my pleasure to meet everyone and watch the process of open source software taking steps forward. I hope that my presentation was able to help with ideas and to point out improvement areas in the software and widgets.

It's completely amazing to me how much functionality we are running on Linux, and I'm looking forward to seeing what we can all do in the future.

Going To Boston UI Summit

After some logistical work with Federico and myself, we have coordinated me going to the Boston UI Summit. I'll be doing a presentation on October 7th concerning issues that I faced deploying GNOME and Linux in a Governmental agency and custom mods and UIs that I had to build. I also will be discussing the areas in which regular users struggle using computers.

I also hope to bring along one of our HP thin clients so that we can demo Compiz and GNOME running over remote display via a network.

If anyone is attending and has topics that you want me to discuss, feel free to respond to this blog. At a minimum walk up and introduce yourself. I don't often get a chance to go to these types of events, and I'm looking forward to it.

Document Centric Desktop

I have been thinking more lately about Federicos "Document Centric" presentation. Document and file management is by far the hardest thing for users to understand. I kind of feel that considering it's 2008, there is very little hope of that situation improving. So I was checking his mockups on ideas for helping people find their documents. Users tend to cringe on learning something new, or having to go into a new program.

So as a rough proof of concept I wrote a ksh script to convert $HOME/.recently-used documents generated by OpenOffice into a .ics file and then allowed Evolution to load the results. I kind of like all date related items being stored in the same software. Email is open all day, which makes it immediately useful. No clickable links obviously, but at least points them in the right direction. I submitted it to the cron for a few power users to see how it runs. I threw it on an internal webserver and they are now using webcal:// to view the data.

file://, easy to see it's a file. Mouse-over tooltip provides full file name



We know the time of the file touch as well, so we can put it inside a 1 hour window.



Here is the WFM code, no attempt was made to make it pretty and useful to other people:

Edit: The paste of the code failed, some of the tags were picked up as HTML. So created a link

Here is the code
