Desktop application start up indicators
by William Cohen 01 Jun '04

01 Jun '04

I am thinking about ways to measure the startup time for various desktop applications. Obviously, a common one used is how soon after a menu item is selected can I do something in the application. However, this does not lend itself to being automated. I assume that most of the applications can be launched from a command line. Are there applications or applets that are started from the menu and do not have corresponding command line invocations? How similar are the gnome applications in startup? Do they use the same set of libraries? Would it be possible to have instrument a function in a common shared library that generally indicates that the application has initialized everything and is just waiting for the user to do something? If there is a common function could do something like: start profiling note time command-line invocation of application <bunch of application initialization> <call library function that indicates application is running> <key function notes time, shutdown profiling> -Will

sound subsystem
by Havoc Pennington 31 May '04

31 May '04

Hi, Arjan asks that we move everything to use libasound rather than esound or OSS. Because ALSA lets multiple apps output sound at once, esound isn't really needed; the only functionality we lose is that remote apps can't play sound on the local system, but that functionality was pretty hosed with esound anyway. I don't have a sense of how many things are accessing OSS/esound directly, or how much work is involved here. Havoc

Hello I have just loaded Fedora onto one of my systems and have tried to load Applix. The install process kept falling over but I managed to force each individual rpm onto the system. However when I try to load I get this message: [ian@sskatings2 ian]$ /opt/applix/axdata/axmain: relocation error: /usr/lib/libgdk-1.2.so.0: undefined symbol: XShmQueryVersion axnet error, axmain already started. /opt/applix/axdata/axmain: relocation error: /usr/lib/libgdk-1.2.so.0: undefined symbol: XShmQueryVersion Ayone any suggestions please as i do like this software and hope to run it for some time yet Regards Ian -- Ian Robertson Tel +44 (0)1224 624811 Tel/Fax +44 (0)1224 781326

gnome-terminal benchmark
by William Cohen 28 May '04

28 May '04

In an effort to create a set of benchmarks for gauging desktop performance I have written up a procedure for gnome-terminal to test the speed that text is sent to the terminal window and written a script to perform the test. I have attached the writeup for the procedure (bench_terminal.txt) and the script to run the test (cattest) to this email. I am interested in hearing people's comments on this test. I know this is only one test and doesn't address desktop issues like program startup time, but we have to start somewhere. We can start to assemble the benchmarks and put them in http://fedora.redhat.com/projects/additional-projects/benchmarks/ -Will Benchmark text output performance of gnome-terminal Frequently output is sent to a terminal window. In Gnome the program gnome-terminal handles the display of text on a terminal window. The, one simple benchmark is to determine the amount of time required to output a large text file to a gnome-terminal window. gnome-terminal is a little tricky to benchmark because has a server. When you start gnome-terminal it connects to the server rather than starting a new child process. Thus, timing the gnome-terminal command will count the time required to communicate information to the gnome-terminal server rather than the time required to actually perform the task. To work around this problem a script is executed within the new gnome-terminal window and the information is saved to a file. Procedure: 0) Get system configuration information hardware and software: CPU: cat /proc/cpuinfo Memory: cat /proc/meminfo Kernel: uname -a gnome-terminal: rpm -qa gnome-terminal xserver: rpm -qa xorg-x11 1) Get the test file, the jargon file from Project Gutenberg: http://www.gutenberg.net/etext02/jarg422.txt. 2) Verify that the file is the same with md5sum $ md5sum jarg422.txt ef9b53f52312ee266c98c8e206d9e823 jarg422.txt 3) Place the cattest script in the same directory as jarg422.txt and make it executable. 4) Run the test on the console of the machine with the command below. The script will generate a file "cattime in the directory with the amount of time required to cat the file to the terminal window. gnome-terminal -e "./cattest" 4a) If the system is set up to run oprofile and you have root access, you can run the same script as root with command below to get some additional profiling information in the cattime file: gnome-terminal -e "./cattest --profile" Additional analysis on the oprofile data can be performed after the benchmark completes. #! /bin/bash # # Simple test to gather data on where gnome-terminal spends # time This is compilicated by the terminal server model of # gnome-terminal. Time taken for benchmark written to cattime. # # When optional --profile on commandline, oprofile used to get an # overall view of what is happening on the system.

GDM Suggestion
by Steven Mackay 27 May '04

27 May '04

Why doesn't someone add a "Make this my default" checkbox to the GDM session chooser? This would mean we could change our default desktop from the login screen and get rid of the Switchdesk utility altogether. And add this to KDM as well, of course. _________________________________________________________________ Express yourself with cool new emoticons http://www.msn.co.uk/specials/myemo

FC2: gnome-terminal takes much longer to startup than Mozilla
by Yusuf Goolamabbas 27 May '04

27 May '04

Hi, I installed Fedora Core 2 on an Athlon 750 with 512MB ram with an Nvidia Vanta II pci video card. After a fresh boot, I timed the following a) startup of Mozilla from the panel till Release notes was rendered b) startup of gnome-terminal from Fedora Menu->System Tools->Terminal till bash prompt The timings for a) and b) on 'cold-start' were 10 and 13 seconds respectively. On a 'warm cache' (ie) start Mozilla/shutdown/start again the timings were 3 and 11 seconds respectively. My expecation is that gnome-terminal is simpler/smaller than Mozilla and as such should startup much faster I was wondering if others saw similar ratio or is there something I might have missed Regards, Yusuf

Small features for improving Abby's experience
by Seth Nickell 26 May '04

26 May '04

A collection of smaller features that have a relatively high impact-on-abby/work ratio: * A post it note feature that allows Abby to drop notes on her desktop, but also drag them to a panel edge where they stick on top (allowing notes to be irritating is key to standard use of notes as reminders). * Show file attachments (but not little attachments like keys?) as first class objects. File attachments are usually more important to Abby than their containing messages * Let Abby mark e-mail messages as tasks, and have due dates set on them. E-mail is the most common place for people to store todo items. Support this existing behavior better. * OO.o help by example: given any OO.o object in the paste buffer let people "Recreate by example", which steps through how to create that item. Most people learn best by example, and it also allows people to build on "things they've seen". With traditional help systems you have to figure out what things are called, and hope that there's specific documentation on an item. This way Abby can use existing documents and things she's seen (people have pretty good "wasn't there something...." memories) to do new things in her own documents. * Files and folders can be moved seemlessly between the panel and nautilus. The same items apply in both. In the distant future, allow snippets of text, images, and other document contents to be directly dragged in. Allows drag-and-drop to have the deferred property of cut and paste, but retains the nice physical aspect. Also allows for multiple items to be naturally in the "clipboard". * Integrate music player seamlessly with the desktop. Use the desktop interface as the primary piece of the music player, not an "extra". In other words, the play list itself lives on the panel. Allow the music browser to be a floating window. Flips the dominance between the window presence and the panel presence. * Mark relevant items as "sysadmin" in the .desktop files and provide a marker on the account that shows them or hides them. Cleans out the menus a lot for Abby. Also adds the possibility for Horatio to browse through a smaller admin-only tool set. * Provide the ability to turn menu items from a non-base set "on", using a checklist. This is *not* full menu editing, but should easily fill Abby's demand for menu editing. More importantly, it reduces pressure for constantly increasing menu sizes over time. On the backend, Horatio can define two application sets: default applications, and applications which are "allowed" but not default. * Collapse volume control to a single slider. * Preferences cleanup, focused around Abby * An improved calculator designed around quick, small "back of napkin" sort of calculations. Not modeled after the deficiencies of physical calculators. Abby will typically be working in another context, so a good calculator needs to be designed for running in small time windows, and make it very easy to get results into other apps. -- Seth Nickell :: Interaction Designer, Red Hat :: <snickell(a)redhat.com>

GDM accessibility support
by Mark McLoughlin 25 May '04

25 May '04

Hey, I was asked by someone about accessibility support in GDM and although I knew GDM had some sort of accessibility support I didn't know what it was or how it worked. I've had a poke and here's what I can tell: * GDM now comes with a set of accessibility modules that can be used to detect certain events happening on the login screen * The two modules shipped with GDM by default are the "DwellMouseEvents" and the "KeyMouseEvents" modules. Both of them allow you to activate the onscreen keyboard from the login screen in different ways. The first by moving the mouse around in a predefined order and the second by clicking the mouse or pressing keys in a predefined way. Take a look at the configuration files in /etc/X11/gdm/modules on FC2. * If you set AddGtkModules=true and uncomment the GtkModulesList line from gdm.conf, you should be able to try this out. You'll also need to install the latest "gok" package from rawhide. I'd recommend setting Greeter=/usr/bin/gdmlogin in gdm.conf also because that seems to be the only way of testing the dwell listener. * So, to activate gok you should now be able to either hold Ctrl-k down for a second and leave go or move the mouse over the login window from top to bottom and then left to right. * gok then comes up, but I haven't figured out how to do anything with it. Its either that gok is broken or I'm missing something obvious. I'm guessing its the form - accessibility stuff is in the habit of being terribly broken :/ So, that's all I have time for now, but if someone had the time to do more on this I'd recommend for a start: - Figure out how to actually use gok once its activated - Get the gok in rawhide pushed to FC2-updates Cheers, Mark.

Firefox and Thunderbird for FC2
by Warren Togami 19 May '04

19 May '04

Fedora Extras has published today firefox and thunderbird packages for FC1 and FC2. These packages have been heavily patched and polished to integrate nicely into the Preferred Applications framework of FC2. This means that you can go into the Preferences -> Preferred Applications chooser, select Firefox & Thunderbird, and the GNOME desktop should fully honor your choice of browser and mail client when clicking hyperlinks in various programs of FC2. http://www.fedora.us/wiki/FedoraHOWTO Please follow the directions on this page if you do not already use Fedora Extras. Report problems of firefox & thunderbird to bugzilla.fedora.us. http://togami.com/~warren/archive/2004/foxbird.sh FC1 users can also use firefox & thunderbird from the Fedora Extras stable repository, but unfortunately the Preferred Applications framework in FC1 is a bit broken. As a workaround you can run this script as your non-root user to set your profile to use these two applications. Warren Togami wtogami(a)redhat.com

Bluecurve after Garrett
by Steven Garrity 18 May '04

18 May '04

For those that haven't seen the news yet, Garrett LeSage, the designer of Bluecurve, is leaving RedHat: http://linuxart.com/news.phtml?sid=760 Garrett did great work and he will be missed. I wondered if anyone could shed some light on the future of Bluecurve and the visual aspects of Fedora/RHL in light of Garrett's departure. I understand that RedHat has been hiring or trying to hire some designers? Thanks, Steven Garrity

The Fedora icons can be found here: http://people.redhat.com/glesage/artwork/Fedora/fedoracore2/icons/ While looking around on Garrett's pages I came across this shocking news on http://linuxart.com/ Leaving Red Hat After a lot of careful consideration, I decided to leave Red Hat two weeks ago. Today is my last day with the company. I worked with several very talented, friendly and enthusiastic people at Red Hat. I am glad I was able to make an impact with things like designing and implementing Bluecurve (the themes, icons, and such you see in Red Hat products and also in Fedora), my work to make Fedora happen, the launch of Wide Open Magazine, the redesign of Red Hat Network, and everything else I did while at Red Hat. It was a great 2+ years.

Performance tuning the Fedora Desktop
by William Cohen 13 May '04

13 May '04

I work on performance tools at Red Hat. I have been told there is interest in tuning the desktop to improve performance. I have a number of questions to help identify the work needed in this area. I would be interested in any answers that people have for the following questions. What is the set of software in the "Desktop" (executable names and/or RPM packages)? What specific performance problems have people observed so far in the desktop? For example heavy CPU or memory usage by particular applications. Another example long latency between event and resulting action. What metrics were used to gauged the effect of software changes on performance? What performance tools have people used so far to identify performance problems with desktop applications? How well or poorly did the performance tools work in identifying the performance problem? Were benchmarks used to test performance of desktop applications? If so, what type of benchmarks were used (e.g. micro benchmarks or measuring the amount of time required to do something in an application program)? Were the benchmarks runnable in batch mode without human assistance? -Will

window managers
by Havoc Pennington 12 May '04

12 May '04

Hi, I'm triaging my bugs and there are a few sawfish issues that I know I won't get around to fixing. Also at this point I think most people wanting a more featureful WM are using a more maintained one, there's a list of EWMH compliant WMs at http://freedesktop.org/standards/wm-spec Even of those included with FC2, there's a good chance KWin and xfwm both work OK with GNOME. So suggestions: 1) if we have a random more-features WM in Core, I think it should probably be one of the more maintained ones instead of Sawfish 2) maybe the right path instead is to put extra WMs in Extras and only the full desktop envs - gnome, kde, xfce, and classic (twm/xterm) - in Core 3) either way, pretty sure someone other than me should be maintaining the package Havoc

Shared Calendars
by Jon Orris 12 May '04

12 May '04

After reading http://www.redhat.com/archives/fedora-desktop-list/2004-April/msg00035.html I've been taking a look at groupware/calendaring solutions, and wanted to share my thoughts on it: System requirements: Performance & scalability: The system should scale to hundreds, and ideally thousands of users. It should be easy to purchase better hardware or add servers in a clustered environment to improve performance and support large numbers of users. Community: Ideally, the project should already have a strong Open Source community around it. Standards: The product needs to support common open components and standards. The use of standard protocols for storage & exchange of data is important. There are some projects that use standard components, but in very unusual ways with no standard protocol for exchange. Some relevant standards are: (The below lists of standards & features, excepting Evolution integration, are from http://www.redhat.com/archives/fedora-desktop-list/2004-April/msg00058.html) http://www.imc.org/ietf-calendar/index.htmliCalendar/iCal (RFC2445) http://www.ietf.org/rfc/rfc2445.txtxCal (iCalendar DTD document) http://xml.coverpages.org/iCal.htmlCalendar Server Extensions for WebDAV (CalDAV) http://greenbytes.de/tech/webdav/draft-dusseault-caldav-00.htmliTIP (RFC 2446) Transport-independent Interoperability protocol http://www.ietf.org/rfc/rfc2446.txtiMIP (RFC 2447) Message-based Interoperability Protocol http://www.ietf.org/rfc/rfc2447.txtCalendar Access Protocol (CAP) transport over BEEP http://www.beepcore.org/beepcore/home.jsp http://beepcore.org/beepcore/docs/profile-cap.htmlICAP (extension of IMAP 4 to support CAP) http://www.wirs.aber.ac.uk/spk/Diary/icap-draft.htm#Overview Features: * Single-Sign On (usually via Directory integration) * user management via "address book users" rather than "system users" * Group scheduling/Meeting creation * Resource scheduling (ie. room availability, notebook checkout...) * Free/busy time * Merging of multiple calendars * import/export iCal * synchronization: * to handhelds/phone * to notebook * to other calendar servers * notification/reminder mechanism * Evolution Integration Anyone have other requirements we haven't thought of here? As an alternative to adopting a particular project, we could build something. The WAF framework, for example, contains numerous infrastructure components that would facilitate building such a system. http://redhat.com/software/rha/tech/waf/ Community Projects: The ones I've looked at so far were mentioned in http://www.redhat.com/archives/fedora-desktop-list/2004-April/msg00058.html My overall conclusion is that Open Groupware and Horde are the strongest existing options. k5n.us (http://www.k5n.us/webcalendar.php) License: GPL Features: Decent PHP calendar implementaion. Does not appear to have groups, but allows creating calendar entries for multiple individuals in 'Waiting for Approval' State. Allows Export as iCal, vCal, or CSV. Allows import as vCal or CSV. Supports LDAP authentication. Database: MySQL, PostgreSQL, Oracle, DB2, Interbase or ODBC. Documentation: Pretty good documentation. Good documentation on the DB schema. UCal from the University of Washington (http://www.washington.edu/ucal/) License: BSD Style http://www.washington.edu/ucal/bsd.html Features: Java Servlets based calendar implementation. Allows import & export in iCal. Has users & groups. Code is of adequate to poor quality. Academic implementation. No built-in authentication mechanism other than simple plaintext passwords. Database code spread throughout as raw JDBC calls. Open Groupware (OpenGroupware.org) License: GPL & LGPL Features: Group Collaboration system descended from the SKYRiX groupware server. Supports group workspaces, calendaring, some document management. Integrates with IMAP for mail and LDAP for authentication. Written in Objective-C, some XML-RPC APIs for Java & perl being developed. Calendar integration works with Mozilla Calendar, Apple's iCal.app and generic WebDav. There is an OGo specific Evolution plugin being developed; I tried it on 1.4.5 and it was able to create entries on the server, but not view them in Evolution. OGo works with Ximian's Exchange Connector v1.2. The version recently released as Open Source by Ximian is 1.4.7, which does not work, but there is strong interest on the OGo lists in supporting it. OGo has a plugable database architecture, and currently supports PostgreSQL and FrontBase. OGo has basic localization support for Latin-1 charsets, but doesn't currently support language such as Chinese or Japanese. This is a planned feature. Horde (http://www.horde.org/) License: GPL & LGPL PHP based groupware system. Supports POP3/IMAP integration for mail, LDAP & SQL for contact management, and has calendaring. The calendar system now support import/export of iCal. It doesn't yet support group calendaring, but this is in development. Supports MySQL and PostgreSQL databases. KGroupware (http://kgroupware.org/) License: GPL Groupware/calendaring solution focusing on KDE frontends. Calendaring supports vCal standard. Calendar entries, like everything else, are stored on the IMAP server as a special type of 'mail' message. This does not fit well with most other software. http://www.redhat.com/archives/fedora-list/2003-October/msg00588.html Chandler (http://wiki.osafoundation.org/twiki/bin/view/Chandler/WebHome) License: GPL, other OS licenses in the future. Interesting project, but is in a very early stage. It doesn't look like full Full iCal compliance isn't scheduled until the 1.5 release, and it is currently on 0.3. It isn't clear if even this allows external clients such as Evolution to access calendar functionality. Currently, development focus is on building out the application framework. The project has full time developers being funded by OSAF. Egroupware: License: GPL & LGPL community Egroupware is a fork of phpgroupware. Some people were dissatisfied with phpgroupware development so they forked. The calendar application is actually on a fork of the PHP-based WebCalendar (separate project).The project is pretty popular as a download on sourceforge. features Reasonable calendar. Primitive "CMS". Webmail app (strangely not based on Horde; based on Anglemail). There is also a Wiki, Bookmarks, Forum, and "Infolog" (notes/todos).The UI isn't very good (lots of clicking around to figure out how to do things, and it's slow so it's a bit frustrating). It looks pretty, though.The documentation is pretty abysmal. There is work with LDAP. technical Written in PHP. It runs very slowly on a test system at Red Hat. Supports MySQL and PostgreSQL only with embedded SQL statements.They have made an attempt to separate out business logic from the UI. Given the scripting language base, I don't know if this is scaleable. Interoperability with existing systems (e.g., IMAP stores) does not seem to be a focus.They do not have real standards support (e.g., iCal).

Fedora cd artwork: Covers, CD-labels etc.

I was wondering, do any of you know of any Fedora artwork that can be made into a cover and CD-label for my Fedora CD-set or maybe even some finished covers or cd-labels? If someone not as artistically retarded as me decided to make something like this, will it be ok (as in legal) to distribute it?

As many others have pointed out rythymbox uses insane amounts of RAM after about one day of use.
