We always are testing ideas for lowering the costs associated with employees that have to work in the field. In years past, many of the EVDO cards required Microsoft Windows drivers to work. So that meant buying full fat clients so that that people could do thin client work.

My coworkers at the police department did some experimental work with the Asus Eee PC and got it working on Linux. It dials the EVDO card perfectly. The NX client loaded and they were able to log into the City network and access the full suite of City applications. Very cool.

So I got my hands on the device and did some cleanups on the servers to make it work better. The screen is 800x480 so when users log in, their desktop icons were displaying "off screen" because they had been configured for 1024x768 or higher. So, I put in a few lines of code pre gnome-session that detects resolution and lowers the icon scaled size:

THUMBS_NAUTILUS="standard"

TMP1=`/usr/bin/xdpyinfo | grep dimensions`
TMP2=` echo $TMP1 | awk -F " " ' {print $2}'`
SCREEN_WIDTH=` echo $TMP2 | awk -F "x" ' {print $1}'`
SCREEN_HEIGHT=` echo $TMP2 | awk -F "x" ' {print $2}'`

if [[ $SCREEN_HEIGHT = 600 ]]
then
THUMBS_NAUTILUS="small"
fi

if [[ $SCREEN_HEIGHT = 480 ]]
then
THUMBS_NAUTILUS="smaller"
fi

/opt/gnome/bin/gconftool-2 --type String --set /apps/nautilus/icon_view/default_zoom_level $THUMBS_NAUTILUS

I'm formulating a plan in my head now to lower the font point size to 8 when they log into this device, but want to make sure I am able to restore their desired fonts when logging into a regular resolution. I'm sure a simple flat file storage of settings will be pretty easy.

Edit: We are testing the 4G model, prices start at $299. 4G On Amazon

The IT services provided for Governmental workers is mostly "internal". This is especially true at a City level. When your taxpayer dollars are spent upgrading a park or adding a bike trail you see it and it has value. Mostly, IT dollars spent are barely seen by the taxpayers. So that's why I feel it's especially important to keep these costs to a minimum and use open source software as much as possible.

It's disheartening to see the number of people in the 23-40-ish age group that have been brainwashed all of these years that if you don't have a personal computer running MS Windows on your desktop that you being hindered. These people are so used to creating islands of data and being able to implement poor techniques that they get angered when their work flow is reviewed for movement to centralized servers. Even when we meet with people, they cannot give you exact things that have been hindered, it's more about how they feel instead of any logical conclusions. So almost weekly around here we seem to have uncomfortable meetings with people that are complaining. We spend more time having these meetings than it would take to learn a slightly different way of working. It seems the most vocal, usually have the lowest skills and just don't want to admit it. What's ironic is that in their mind, it's OK to have training classes to learn Office 2007 with its new interface, but not worth learning the differences in OpenOffice. Lately the question has been posed to these people: If we spend $500,000+ to install Office for year one, will you be able to produce work faster or reduce staff size? Of course no one can guarantee this is the case.

The point that I am making is that if you find out your local Government is using open source software, go to your commission meetings and make sure that you speak and show support for them. Tell your elected officials that you want files saved in file formats that will open without proprietary software. Tell them that purchases of these unneeded proprietary packages is taking money from your wallet and providing you with no improvement in quality of life. So many Goverment agencies have forgotten that we work for *you*!

Everyone is back in the office so we are gearing up for deploying the 3D desktop with our thin clients. One issue that we have finalized is how many settings to allow our users to configure. The ccsm utility is great, but has way too many things that they can do to make their sessions work poorly. So what I did was build 4 settings; 1 for 2d and 3 for 3D. I then created a simple GUI with Glade (image below). This will allow a diverse group of settings that are all tested and QA'd by me in advance. This lock down feature will reduce calls to our support group.

I've mentioned it in the past, but one thing that eludes developers is the passion that users have for eye candy and especially printouts. Regular computer users just absolutely *love* to hold paper, even if it's easier and more efficient to do the same tasks with their software.

Evolution really needs a simple plugin system for creating printout templates. I would love to contribute templates in this manner, for inclusion in future releases. I suspect many others feel the same way.

We had an immediate need to create a printout that should come from Evolution itself. I ended up just writing my own little program using the CreateSimple perl library which allows for easy generation of PDF files. The script opens an .ics file and then formats the output. It only prints boxes for dates with appointments. All of the current Evolution printouts are time based, and this one is more event based.

This is the kind of stuff that would move Evolution ahead of competing products in the minds of regular computer users.

If you work full time and own a home, it's very easy to lose almost all of your hours of the day. 4-5 times a week I try and get on my bike and ride around my neighborhood. This weekend was particularly wonderful. I always enjoy seeing pictures from around the world, these are from my neck of the woods:

We use a development tool for City applications that is using the Motif widgets. When I have more time, I'll create a detailed blog about why we continue to use this product. It really works very well, and allows for developing business applications with just a few clicks.

I suspect Motif applications are not tested on Compiz heavily and we have two minor problems. If anyone wants to chat with me about a possible bounty, find me on the IRC as 'dave_largo' and private me to get my attention.

The first issue is that about 1 out of 100 times a motif dialog box will open as 1 pixel by 1 pixel. See the two shots below, one is how it *should* look and the other is how it looks when if fails.

(note small emerald container hovering over the application)



(The next time that I clicked on it, it worked fine)



The other issue is that this application loses focus when you move your mouse off the UI. On Metacity, it works correctly. So the users are having to always keep their mouse hovered over the top of this screen, which will force us to re-train people.

Off and on I have been tinkering with screenlets. Poking around, I found that the dbus-python package that ships with OpenSuse 10.2 does not work with them. After some updated RPMs were installed, things started working. I went through the shipped screenlets and the extra third party ones and installed those that were appropriate for business and to be run on a server. (I don't want users watching the temperatures of the CPUs :) ). I also did not feel the screenlet manager could be deployed to users, and created unique icons for each application. It all seems to work fine.

Screenlets are written in Python, which should allow us to rapidly develop some small standalone applications that look great from the users perspective. I already have a few ideas:

- An application that shows realtime status at our recreation sites, money received in the current day.
- An application to show the items on the upcoming Commission meetings via iCal.
- Show current and upcoming meetings in conference rooms.

Thanks to those working on that project, this will allow the Linux desktop to continue to have excellent presentation. As much as we hate to admit it as IT people, much of the success of technology comes from eye candy.
