Radek Vokál: LinuxAlt 2009 - Fedora 12 presentation

2009-11-07T15:20:58+00:00

After insisting that I won't attend the LinuxAlt conference this year I was asked to give a Fedora talk as substitute for one of the scheduled talks. Why not, fortunately my Red Hat colleague and good friend drove me to the conference, thanks Ondrej!

I was surprised (in a good way of course) that the conference has a very good attendance. Both rooms (for apx 150 and little bit more than 80 people) were full up! I've watched talk from Michal Schmidt about Trusted Computing, which I found really interesting and I hope Michal will publish his slides somewhere.

My talk was right after Ubuntu Karmic Koala presentation. Well, I thought that I won't get that many people for my talk, but the room was crowded. It took full hour to go thru all the highlights of Fedora 12 and I even get some questions at the end and few positive comments :-) .. Here are my slides (in czech).

LinuxAlt continues tmrw. Dan Horak will be giving a talk about Open Source development and also Milan Broz and his presentation about LVM will be interesting, as he's one of the key developers and always shares some insights from the project :-)

Tim Waugh: 80s computer games I remember

2009-11-07T14:08:37+00:00

When I think about it, I can remember more games I used to play on my Commodore 64 than I expect to. Here’s what I’ve managed to recall.

Monty On The Run
Crazy Comets
Attack of the Mutant Camels (weird!)
Hovver Bovver (brilliantly English)
Outrun
Pod — I’m sure that’s what it was called but can’t find any reference to it anywhere. Little man with big feet who had to jump across streams and walls and things. If he fell in he would turn white, grow angel wings, and fly up to heaven while music played. And I think maybe there a Welsh connection?
Paperboy
Nebulus
International Karate+
Little Computer People
Winter Games
Toy Bizarre
Ghostbusters
Falcon Patrol
Blade Runner
There was some kind of football game, don’t remember what it was called. Actually I think the copy I had was translated into German… looking around it must have been a version of Emlyn Hughes International Soccer.
Cauldron
Booty was the first one I had, a pirate treasure platform game with colour-coded keys and doors. At the time I had it plugged into a black and white TV set so that made it a bit more challenging!
Haunted Mansion or something with a similar name. Don’t remember a lot about it except that it was quite a simple game, but enjoyable.
Orpheus and the Underworld (but don’t remember much about it)

Alexander "dreamer" C.: Museum N8

2009-11-07T11:17:44+00:00

And another awesome collaboration between Puik. and Dyne.org!

This weekend we are working on an interactive installation for the yearly Museum N8 festival at the Dutch Institute for Media Art (NIMK).

There will be an 8bit/acid themed VJ set that can be interfaced with 3 gamepad-controllers including force-feedback! All implemented through javascript using the FreeJ software.

See n8.nl for more info.

Very cool stuff. We are rounding up the scripting now and will setup the installation this afternoon.

Sankarshan: Looking forward to some improvements

2009-11-07T04:06:42+00:00

I have been using Transifex based systems for a couple of days/weeks now. And, in line with what I did mention on my micro-blog, Transifex and Lotte make things really easy. The coolest devel crew makes that happen. And, since they lurk online and engage with their users, every little tweak or, improvement that is suggested and considered makes the consumers feel part of the good work they are doing. Good karma and awesome excitement all around.

At some point in time during the week, I’d put them in the tickets as feature enhancements. However, for the time being, here’s a couple:

Lotte should allow me to click on a file that is not yet translated for my language and, add it to the collection. If I recall correctly, the current way to add it is to download the .pot, convert to the appropriate .po and, upload it with comments etc
Lotte needs to allow “Copy from Source”. This should accelerate translation by removing the extra step of having to actually select, copy and paste. This comes in handy when translating strings within tags or, brands/trademarks and so forth
Handling and using translation memory could be built into Lotte. For a particular file in a specific language within a project, it could perhaps provide suggestions of translated words. In the future, allowing teams to add their glossaries would make it a more powerful tool too. Having said that, I’ve always wondered what happens when team glossaries are created from files across various projects – is there a license compatibility soup problem that could crop up ?
A Transifex installation could provide notifications of new files or, updated files for the language. This could be limited to the files for which the last translator is the person receiving the notices or, ideally, could be for the language itself.
Statistics – providing each language a visual representation of commits over time or, per contributor commits would also be a nice addition

So much for Transifex, in fact, I need to write out all of that in a nicer way so as to allow the possibility of these turning into GSoC projects within Transifex.

Coming to Virtaal. With lokalize being unbearably useless for me (it adds garbled text or whitespaces into files when using the stock F11 supplied one) and, before it is commented, no I haven’t filed a bug yet, getting the files done was a bit more important at that specific point. So, mea culpa. But I do check with every yum update and, it is still the same. The specific issue with Virtaal is that each time one gets a new string loaded for translation, the text input area loses the input method details. Which means that it is a constant game of switch back and forth between the inputs. Sadly enough, this is the only software that currently works for me (I don’t want to set up a local pootle/transifex instance and, do web based translation)

Eric "Sparks" Christensen: Amateur Radio in next month's Linux Journal

2009-11-06T22:20:00+00:00

I just pulled down the December version of Linux Journal a couple of minutes ago. I made it all the way to page 4 and read that next month's issue would be on Amateur Radio (or at least some portion there of). I'm excited to see that Amateur Radio and Open Source has been written about together because they do share so many similarities. Amateur radio operators used to build all their equipment and help mentor each other on developing better communications stations. Open source software is very similar to that. While I might not build my transceivers, I do still build many of my antennas which is something I enjoy. Amateur radio operators, also like OSS developers, are in it to help people and have some fun in the mean time. Yep, Amateur Radio and OSS... a match made in heaven.

Seth vidal: playing with another yum-util

2009-11-06T22:18:07+00:00

This morning I was annoyed by a perl module which took the output from yumdownloader –resolve –urls, screenscraped it, downloaded the pkgs then passed them to rpm -Uvh. Let’s ignore all the things which could break there – just the ugliness of it.

So I hashed this together:

http://skvidal.fedorapeople.org/misc/yumpipes.py

I’m not sure I like it yet, but it is a start.

You can pass multiple items on the command line doing multiple things like:

yumpipes –install=foo –install=baz –update=quux –remove=sendmail

and you can pass –dry-run which runs the transaction in test mode

and you can pass –report-only which only spits out what the transaction would do.

and the output from the transaction and from the –list option is pipe-delimited so people using awk or cut can easily parse it.

finally. the error codes, while not great, are somewhat consistent.

flames welcome.

JoergSimon: Chemnitzer Linuxtage 2010

2009-11-06T20:16:09+00:00

Since years we are present at Chemnitzer Linuxtage - CLT and always had a great and successfull time - Max wrote a great report about the 2009 event!

You can see Max's talk "Innovations in the Fedora Project"

On FAD EMEA 2009 a decision was made, to make CLT one of the big events for EMEA in 2010.
Today, the CfP is out and i will take care for our "Call for Presentations" which means to have a booth, dev-room etc. ...
If you are interested to give a talk, you are invited to follow the "Call for Lectures"
We will try to get a separate Dev/Project Room - then we can give our own Talking Track independent from the official "Call for Lectures". Update on that soon!
More Details on Fedora CLT 2010 Event - expect more updates soon.

The German CfP from the CLT Team:

Jonathan Dieter: On binary delta algorithms

2009-11-06T18:49:44+00:00

Yesterday I was reading this update (warning: still subscriber-only) on the Courgette delta algorithm that will be used by Google to push Chrome updates.

The article focused on potential patent problems with the Courgette method, but also described how the Courgette method works and also suggested that deltarpm (which I maintain in Fedora) could learn from it.

While not wanting to argue that particular point (I would love to get a hold of the code and see how much it would actually help our deltarpms), I do want to correct a couple of misconceptions about deltarpm.

Courgette, deltarpm and bsdiff (the tool) are all based on the bsdiff algorithm, which is very efficient. The problem comes when dealing with binaries. One small change in the source code will normally result in many small changes through the binary as the locations of pointers change.

(In the graphs provided, location two is a byte of data that has changed, while locations 3-6 and 21-24 represent two relative jump pointers to the same location. In the new binary, the location has changed by 74 bytes.)

The first graph is that of a naive delta using the bsdiff algorithm.

Note that the delta is four bytes of not-very-compressible data (out of 12). Not so great.

The second graph is roughly what courgette does with the same data. It does some disassembly to convert the relative pointers into labels. When applying the delta, courgette will disassemble the old file, apply the delta, and then reassemble the resulting not-quite-machine code into machine code.

Note that we’re down to a one-byte delta! Wonderful!

Now, the final example is how both the bsdiff tool and deltarpm work. They use the algorithm Colin Percival describes here which has an interesting twist when dealing with binaries.

When the locations change in a binary, they tend to do so in a consistent way. As deltarpm is doing its comparison, it adds an extra step. If less than half of the bytes in a segment have changed, deltarpm will do a byte-wise subtraction of the old binary’s bytes from the new binary’s bytes. This is then stored in an “add block”, which will mostly contain zeros.

While this does give us a block the size of the old binary, this block is very highly compressible (especially using bzip2).

While we may not be getting the compression levels that we might using courgette, we are doing far better than we would be using a naive bsdiff algorithm.

While courgette obviously has the advantage of size, it’s primary disadvantage is that it is very archicture-specific. The algorithm must know how to both assemble and disassemble binaries for each architecture it’s built for.

The advantage of the “add block” method is that it is generic to all architectures, but its disadvantage is that it won’t reach the same delta levels as courgette.

Having said that, I still haven’t had a chance to do any direct comparisons, which may tell us how much better courgette is than deltarpm.

(Updated: Tried to make it clear that bsdiff (the tool) doesn’t just use a naive bsdiff algorithm)

Sayamindu Dasgupta: Making Books Available

2009-11-06T18:35:18+00:00

Its all over the web now – the Internet Archive has opened up over 1.6 million books for the OLPC XO laptops and in general, any machine running Sugar. Before going into anything else, it makes sense to provide a more specific meaning of “opening up” here – it involves two main objectives completed at the Internet Archive end:

Making sure that the books are readable in the XO, keeping in mind its relative low-end hardware specs and disk-space limitations
Ensuring that the books are available via a standardized catalog format, so that one can find, browse and download books easily using a tool more tuned for the purpose (think of feed-readers versus blog-entries in a web-page)

Now that the books are available (not just from the Internet Archive, but from a number of other sources as well), the next step is to figure out the best possible ways to actually make these books available to the XO and Sugar users. The major constraining factor is bandwidth, we do have deployments with zero, or very limited Internet connectivity, and perhaps these are the deployments which need access to these books the most. I spent most of this week working on implementing a feature in the Get Books activity which would allow books to be distributed via what has been jokingly called a sneaker-net (or sandalnet/chappalnet, if you prefer those forms of footwear). The idea is very simple – at a centralized location with Internet access, choose a few thousand books (size of a typical book is usually a few hundred KB or less), put them in a USB pen-drive and add a OPDS catalog to the mix. Make copies of the drive, and send them to the schools without connectivity. The latest version of Get Books would recognize the drive, and let the student browse through the collection, search for books, and add whatever she wants to the Sugar Journal. Once a book is in the Journal, it can be shared among all the students using the Journal object transfer support in Sugar, or via the Read Activity directly. So essentially, you get a Library on a Stick, with thousands of books, something which, till now, in its physical form, has been largely restricted to better equipped (and usually richer) schools.
Of course, even larger collections can be distributed if a School Server (XS) is present in the mix (due to the fact that the school server can have a larger disk in it), and support for this type of distribution method involving the XS would hopefully appear within the next few releases of Get Books.

Paul W. Frields: Upside down.

2009-11-06T17:20:22+00:00

I’m getting on a plane in a few hours that’s going to take me from Washington DC to Los Angeles, and then just a couple hours after landing, another one from LAX to Brisbane in Australia. Thanks to the timezones crossed, plus the international date line, I leave LAX late Friday night, and arrive in Brisbane near dawn on Sunday morning.

I’ll be there (along with Spot) until next Friday, when we fly back to the USA. With the timezones the other way around, I think I get back around last Tuesday, meaning plenty of time to work on more Fedora bits before the release!

Well, I think that my numbers may be a bit off there, but in any case, I’ll be on Down Under time for the next week or so. I’ll definitely have access to email but obviously it will be a bit harder to catch everyone during the day on IRC.

Let’s all be focused on getting out the best Fedora release yet. I want to give my most sincere and awe-struck thanks to everyone in our community who’s contributed to the upcoming Fedora 12. I’m using the pre-release now, and it’s been fantastic! With new virtualization features, desktop polish, and developer goodies, I think many people are going to like what they see.

OK, off to check weather in Brisbane, and then pack.

Hedayat Vatankhah: New Fonts in Fedora Supporting Persian

2009-11-06T15:27:33+00:00

As I said before, after exploring some Persian fonts for legal issues and finding that most of them cannot be included in Fedora, I decided to package SIL Arabic script fonts. So I packaged SIL Scheherazadeh and Lateef fonts, and they are available in Fedora repositories now. SIL Scheherazadeh font should be included in Fedora 12 and later versions, as a font required by Persian locale by default. I hope to be able to find some other fonts to include in Fedora. However, almost any Persian user will need the common fonts mentioned earlier, so I’ll create a package of those fonts an put it somewhere for interested people. Those fonts have unclear legal status, but they are expected to be free to distribute and use.

Fedora 12 is coming and I’m waiting for it! I’ve installed Beta version already, but do not use it much, and waiting to completely replace my Fedora 11 with it. It contains many interesting features, and is generally “better”! There are lots of small changes which are not listed, but improves the final experience.

I am going to create a rpmfusion based Fedora remix containing some other interesting software specially considering Persian people. Hopefully, with the help of others like people in fedoraproject.ir, we will create an interesting Fedora remix for Persian people.

I’ll talk about my Yum related plans later!

Una buena noticia para los que quieran sacarle el máximo provecho a sus ATI.
AMD ha liberado la más reciente versión de su driver de video ATI Catalyst (9.10). Estos drivers (propietarios) pueden ser descargados desde la página de drivers de AMD/ATI
Lo mejor de esta versión es que es posible integrarlos en máquinas con kernels 2.6.30+, por ejemplo, máquinas con Fedora 11. Estos drivers aún no solucionan el problema de la corrupción del cursor mientras se está viendo videos o cuando compiz está activo, sin embargo igual vale la pena darle una vuelta! Aunque claro, lo mejor que pueden hacer es comprarse algo que tenga video Intel...

Frederic Hornain: JBoss Tools Installation on Fedora 11

2009-11-06T11:02:33+00:00

As I am currently working with JBoss seam, I had to install JBoss Tools on my Fedora Eclipse 3.4.2 – Fedora 11 -.

So in order to share the procedure to every one and mostly to avoid to forget or lose it I decided to write it on this blog.

In addition, it permit to avoid eclipse/JBoss Tools problems dependence such as :

And Errors such as :

Cannot complete the request. See the details.
Unsatisfied dependency: [org.hibernate.eclipse.feature.feature.group 3.2.4.v200909151014R-H192-GA] requiredCapability: org.eclipse.equinox.p2.iu/org.eclipse.wst.xml.core/1.1.0

So these are the steps :

I] Install Eclispe on your Fedora.

I.I] Open a terminal as standard user – here mine “fhornain” – and be root.

[fhornain@localhost ~]$ su -

[root@localhost ~]# yum install java-1.6.0-openjdk-devel

[root@localhost ~]# yum install eclipse-platform

II ] Launch eclipse.

II.I] Indeed you should select in you Fedora main menu bar Applications > Programming > Eclipse

If not, launch a terminal and run the following command :

[fhornain@localhost ~]$ eclipse -vm /usr/bin/java

Rem: Change the path /usr/bin/java if it is not your java default location

Then you should see the eclipse starting banner – see below -

II.II] Then eclipse should ask you where you would like to save your projects – see image below -

The default location should be fine – well, for me -

II.III] Then Welcome screen appears – see below -. Close it with a click on the top left cross.

III ] Install JBoss Tools

III.I] When Eclipse starts, go to Help > Software Updates. The following window should appears :

III.II] Then click on the tab named “Available Software” – see below -

III.III] Then click on button “Add Site” on the right of the window – see above – :

Rem: Change the path /usr/bin/java if it is not your java default location

You should see appear the following window :

IV.II] Then click on the main menu bar File > New > Project and the following window appears – see below -

Then Choose your new JBoss Seam Project and name it.

BTW, do not forget BIRT otherwise you will not have JDBC Connectors

Enjoy !

Lennart Poettering: Public Service Announcement

2009-11-06T10:14:00+00:00

Folks! Since quite some time now the kernel exports the DMI machine information below /sys/class/dmi/id/. You may stop now parsing the output of dmidecode thus depending on external tools and privileged code.

For example, to read your BIOS vendor string all you need to do is this:

$ read bv < /sys/class/dmi/id/bios_vendor
$ echo $bv

Which is of course much simpler, and cleaner, and safer than anything involving dmidecode.

Thank you for your time!

Thomas Vander Stichele: Dedicated separate Firefox windows

2009-11-06T09:59:59+00:00

Dear intarweb,

here’s what I’d like to be able to do. I would like to start a completely separate Firefox window, in a separate process, with a given webpage. This process should be completely separate from my regular browsing, not take new links in its window when I click links somewhere else (usually they go to the most recently opened window), not crash when the regular firefox process crashes, and not bog down because my regular firefox goes to 100% CPU and beyond.

It seems to be hard to google for this idea; is it possible ?

Abhishek Singh: How to setup Key based SSH authentication?

2009-11-06T09:20:28+00:00

Introduction: SSH (SSH client) is a program for logging into a remote machine and for executing commands on a remote machine. It is intended to replace rlogin and rsh, and provide secure encrypted communications between two untrusted hosts over an insecure network. X11 connections and arbitrary TCP ports can also be forwarded over the secure channel.

Chitlesh Goorah: SystemC License again ! Communicating with OSCI Board

2009-11-06T08:42:05+00:00

This is no secret for everyone that for a while I wish to see SystemC in Fedora repositories. However, a small glitch within the license in terms of redistribution prevents us from shipping it.

Jeremy Bennett is very kind to introduce me to some members of the OSCI board. I have already contacted two weeks them ago. Till yesterday, I haven’t got any reply. So I’ve resent a reminded to those board members in hope to understand the reason behind this glitch.

In the meantime, David Cabanis, the SCLive maintainer as well is wishing to see this licensing issue resolved.

Chitlesh Goorah: choose EL or FEL — FEL package list

2009-11-06T08:24:13+00:00

It was asked several times to publish a list of FEL packages. Maintenance of that list is a blocker. We don’t want to publish obsolete data since Fedora’s development cycle is 6 months. 6 months fly back very quickly. Hence an automated mechanism is advised to solve this issue.

We also receive some requests from users for additional data exposure :

A friend of mine wants concrete data which he can analyse before choosing whether CentOS or Fedora is appropriate for his analog and characterisation team. The choice of Fedora or CentOS depends on the features and bug fixes on the EDA tools. A tradeoff which the user has to make.
Some metrics to reflect the critical path in packaging for a particular design flow and which packages really need to be updated or rebuilt.
Some metrics which are useful for the Spin maintainer to track the major changes done by multiple packagers. These metrics will eventually help to allocate required time for proper testing and integration before release.
A list of FEL packages which Fedora Ambassadors can quick go through to help someone during an event.

Every two weeks, I ‘m auto-generating a basic html page listing all FEL packages and their versions with respect to Fedora and EPEL.

Adam Williamson: Fedora 12: Crunch time

2009-11-06T06:11:39+00:00

It’s been a crazy week. We’re still pushing to make the Fedora 12 final release on time but without compromising on quality. It’s been a little hairy over the last two days but we’ve got what we think is a solid package set in at last, and a first release candidate build has been cut. We still need to do some heavy testing on it and make a final call on whether we’re going with the planned release schedule – that will happen on Monday – but at the moment I’m hopeful. We’ll make the right decision either way, if we ought to slip the release we will do, and Fedora 12 should be one of the highest quality Fedora releases for a while.

So, what can you do to help? Oh, so much! First, don’t let the magic words ‘release candidate’ mean too much: the RC compose per se really only exists to test the actual image compose process, and the DVD / multi-CD installation process. The bits it contains are just the same ones in the repositories. If you have an F12 installation already – say, from the Beta – and you update it daily, you’re getting the exact same bits. You can also get on the F12 train from the nightly builds, and testing that install path is just as valuable as testing the DVD or net install paths.

So whichever method you choose to get on the Fedora 12 train, we need you to test out the package set that will be hitting the repositories tomorrow – there’s a small number of updates from today, but they’re all very significant ones – and make sure it works. We want to hear about any catastrophic problems, and especially about any cases where the packages from 2009-11-06 work worse than the ones from 2009-11-05. That’s key. Post a comment here, file a bug and mark it F12Blocker, tell us on a mailing list or find someone on IRC – any of these will work in such a case.

If you have spare systems, drives, partitions or virtual machines we certainly need installation testing, either from the RC compose or from doing a network install from a Rawhide mirror. We have the installation test matrix up here. There’s a couple of ways you can use it. The easiest way is to just do an install the way you usually would have done, then see which cell on the table that installation method maps to. If it’s not filled in already, fill it in. If it’s filled in but your result doesn’t match what’s in the table already, edit the page to say so – and include a link to a bug report, or contact details, some way for us to follow up! The other way is to look at the table first, and look for tests that haven’t been done yet – white spaces. See if you have the hardware or configuration needed to do the test, and if you do, then do it and fill in the cell. In all cases, if you try an install and hit a serious bug, make sure to file a report to bring it to our attention.

The bottom line is, the more testing the better; just run F12 code anywhere you can and let us know where it’s broken. Information is always good.

It’s been incredible to see how hard everyone in QA, release engineering, development and documentation teams are working to get this release done and make sure it’s great. I’m sure the other teams are all working just as hard, as well. I don’t think there’s many other distributions where I could start the day watching one of Red Hat’s full-time X.org engineers start working on an issue in France in the early morning my time, discuss it with more developers in Europe and the U.S. during the course of the day, and go to bed in the evening (okay, early morning) knowing a couple more paid Red Hat engineers are working on it in Australia. It’s a great process to be a part of, insofar as I’ve been helping by running around like a headless chicken bashing everyone in sight over the head with the blocker list and demanding fixes yesterday!

On another note, congratulations to Ubuntu and Mandriva for their 9.10 and 2010 releases. I hope to get some time to play with MDV 2010 once this craziness subsides

Juanjo Martínez: Fedora 12 Release Party, Valencia (ES)

2009-11-05T22:40:16+00:00

As Fedora ambassador I’m going to host a release party in Valencia.

I’m not sure about how many people will come to the event, because I don’t know if there’s a Fedora community in Valencia, but I’m sure it’ll be fun (no matter if we’re two or twenty).

In fact, this little event will be a proof of concept. As far as I know there are some Linux user groups and Linux user associations in Valencia, but they’re quite dormant. So the motto of this release party will be very simple: come to hang out for a beer (or a coke, or whatever you like to drink), and chat about Fedora, Linux and free software.

The meet will be next November 20th, from 20:00h, at The Black Sheep pub (it’s a nice and spacious place).

There’s a little poster for the event. If you’re in the area, it would be great if you come!

Tom 'spot' Callaway: going walkabout (well, flyabout anyways)

Tomorrow, I am taking my the longest plane ride ever: I'm going to Brisbane, Australia for a week.

Sadly, it is not a week of vacation, but instead, a week of building bridges and improving communications between groups at Red Hat.

Okay, so maybe I might sneak out of a meeting or two to go see a Koala Sanctuary. This is my first trip to Australia, and will be the Fifth continent I have had the chance to visit. (Only Africa and Antarctica to go!)

I still have a ton of stuff to do before I go (including laundry), but I think all of my Fedora 12 bits are in the right place, so that can go forward without me (or Paul).

"Kulbir Saini": News : ATI Drivers 9.10 Working with 2.6.30+ Kernels

2009-11-05T22:07:55+00:00

AMD released the next version 9.10 of its ATI Catalyst display drivers for Linux nearly a fortnight ago. The drivers can be download from ATI Catalyst™ 9.9 Proprietary Linux x86 Display Driver Page. The good thing about this version is that a lot of people are reporting that they can get it working on 2.6.30+ kernels. These drivers are lifesaver for people want to keep everything upto date. The corruption around cursor is still present while watching videos or with compiz enabled.

Note1 : The installation process is same as version 9.8 and can be access at How To: Install ATI Catalyst (fglrx) 9.8 Drivers on Fedora 11.
Note2 : If you want to configure dual display follow How To: Configure Dual Display with ATI Radeon (fglrx).

Will over at the Miro project, that super cool Open Source media player, sent me a link today of their Miro Community site. It is a video aggregation site that allows for communities to collect all of their video in one place even if they were originally posted elsewhere. To that effect he has also set up a GNOME Miro Community site. I know we have a bunch of great videos talking about GNOME and showing off its features. This is a shout out to people who have great GNOME related video content to go ahead and start aggregating those videos so others can find them. Let’s start building a community of open video showcasing our favorite open desktop!!!

FOSS Docs: Building Publican DocBook Projects in Maven using jDocBook

2009-11-05T14:48:15+00:00

Situation: I have a Docbook project that builds in Publican. However the same book also needs to be able to be built by a different team using Maven and jDocbook. How do I make this happen.

1 – You’ll need a Maven POM (pom.xml)

Publican 1.0 currently no longer includes POM creation. The previous generation of Publican, ie 0.45 and earlier, would produce a Maven POM (pom.xml) with the command make pom. Either generate one with a pre-1.0 version of Publican or make a copy of a pre-existing one.

2 – Add the jboss.org Maven repository configuration to the POM
The POM produced by Publican lacks the repository configuration to actually make it work.

The missing sections are:

<repositories>
    <repository>
        <id>repository.jboss.org</id>
        <name>JBoss Repository</name>
        <layout>default</layout>
        <url>http://repository.jboss.org/maven2/</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

<pluginRepositories>
    <pluginRepository>
        <id>repository.jboss.org</id>
        <name>JBoss Repository</name>
        <layout>default</layout>
        <url>http://repository.jboss.org/maven2/</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </pluginRepository>
</pluginRepositories>

These are the repositories that contain the jDocBook Maven plugins as well as the default JBoss style plugins. Just add this XML to the POM within the scope of the <project> tag, e.g. just before the <build> element.

3 – Make sure the POM matches the book.
If you didn’t use Publican to generate a new POM and are reusing a POM from another project then the <properties> section will probably not match your book and will need to be edited.

<properties>
     <translation>en-US</translation>
     <docname>A_User_Guide</docname>
     <bookname>A User Guide</bookname>
</properties>

<docname> needs to have the same value as the file name (minus the .xml) of the starting XML file of your book, i.e. the one containing the <book> or <article> element.

<bookname> is only used in the <name> element of the <project> … and nothing in this POM makes use of it, so it doesn’t really matter what you put here. I’d set this to whatever the title of the book is.

4 – Add entity declarations to the top of each of your XML files.

Publican enforces some good habits, like having all your entities declared in one file. However entities actually need to be declared in every file that they are referenced from. Publican as a part of it’s “pre-build” process inserts the declarations into each file for you. jDocBook doesn’t do this however so you need to add a reference to your entities file (A_User_Guide.ent) in the header of every XML file that uses those entities. If you don’t do this, the entities will not populate in your book.

<?xml version='1.0'?>
<!DOCTYPE preface PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"
"http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd" [
<!ENTITY % BOOK_ENTITIES SYSTEM "A_User_Guide.ent">
%BOOK_ENTITIES;
]>

Note Publican is smart enough not to duplicate this during its own build process.

4 – Specify both role and language for <programlisting>

In Publican, to make use of language syntax highlighting in <programlisting>, you specify the attribute language with the value of the language that the <programlisting> contains. This is actually the correct behavior according to the Docbook specification.

<programlisting language="xml">

However the underlying highlighting library that jDocBook uses requires that the language be specified with the attribute role.

<programlisting role="XML">

You can simply specifying both attributes so it works in both systems.

<programlisting language="xml" role="XML">

Note that Publican requires the value to be lowercase, and jDocBook requires it to be uppercase.

EDIT: For Publican 1.0, the capitalization of the language value needs to match the LANGUAGE column athttp://search.cpan.org/~szabgab/Syntax-Highlight-Engine-Kate-0.06/lib/Syntax/Highlight/Engine/Kate.pm#PLUGINS.

That’s the easy stuff. Dealing with Publican’s Common Content is a little trickier. In many cases you can simply supply a Feedback.xml, Conventions.xml and Legal_Notice.xml to satisfy the fallbacks. But that isn’t really a good long term solution for a couple of reasons which I’ll deal with that another time.

Maven will build this book with the command mvn compile. The Publican supplied POM will build html, html-single and PDF versions of the book using the default JBoss documentation styles.

If you do not want to use the default JBoss documentation styles then you will need to create your own jDocBook style Maven plugin. This isn’t terribly difficult but is also a topic for another time.

Mel Chua: Mel : clothing :: technology : most people

2009-11-05T10:00:48+00:00

It occurred to me on the bus from the mall last night – after the Mel Gets A Business Casual Wardrobe adventure – that perhaps clothes are to me what technology is to most people.

I want to be warm, at least marginally socially acceptable, and Not Spend Money. I don’t want to update my wardrobe for each new fashion season; I don’t even know when those seasons start or end or how that sausage gets made, and I certainly don’t want ruffles on my shirts now – or ever – regardless of whether they’re in fashion or not. I don’t know how to sew, nor do I have the time to make extensive modifications, so I need stuff that works for me straight off the racks. (This last sentence may change; I can’t stand having something I don’t know how to hack, so acquiring these sorts of skills may be in my future.)

And how is one brand of trousers different from another? And why doesn’t everyone use the same sizing system? Really, all I do is get up in the morning, find a clean pair of jeans, grab the t-shirt on the top of the stack, and I don’t care about anything else because I want to spend my time on other things. Open source, for instance.

So when I meet someone that’s into clothes, I try to listen and understand why they’re fascinated with it, while knowing full well that I probably never really will be. And sometimes I learn fascinating things, like how denim has a funny weave that I forget the name of (update: twill!) and it’s nice to encounter those little nuggets of interestingness… and that’s all.

And if it’s okay for me to feel that way about clothes – and I think it is, because I do – then it’s got to be okay for other people to feel that way about the stuff I love. And I should make sure that the world I help to build is a world where both these things work out just fine.

Richard Hughes: GNOME Color Manager and initial scanner support

2009-11-05T09:29:04+00:00

Late last night, after a few hours of intense refactoring (to allow udev based devices, as well as xrandr based devices) we got the initial scanner support working:

Scanner support

This lets us support printers and digital cameras pretty easily too. At the moment we just need to figure out how to make gnome-scan make a scan for us and save it in tiff format, and then we can get the calibration working for all types of scanners. Of course, you need a precision printed reference image, but you can get these pretty cheaply from Wolf Faust.

Then, we need to work with the gnome-scan guys to agree an interface so that gnome-scan knows what profile to use for each device. Either a library or DBus interface (with calls in either direction) are being considered, although I think the session-activated dbus interface is probably going to win. There’s still quite a bit of integration work to make CUPS ICC profile aware, but that’s on the list after scanners are working. After all, you need a calibrated scanner to calibrate the printer. Help is always welcome, so please checkout the code and help find bugs.

Gianluca Sforna: Staccata la spina a rawhide

2009-11-05T09:04:30+00:00

Quelli di voi che si sono imbarcati nella installazione della versione Alpha o Beta di Fedora 12 hanno avuto yum configurato per scaricare i pacchetti aggiornati dal repository rawhide.

Da oggi invece, con l'arrivo del pacchetto fedora-release-12-1 i repository di default sono stati riconfigurati, disattivando rawhide e attivando il repository updates.

Dopo aver installato questo aggiornamento, assicuratevi che nella directory /etc/yum.repos.d siano presenti solo files *.repo. Se invece fossero presenti files .rpmnew, usateli per sovrascrivere il corrispondente file .repo; ad esempio, in caso sia stato creato il file fedora.repo.rpmnew si può eseguire il comando:

mv fedora.repo.rpmnew fedora.repo

In ogni caso, se avete dei dubbi lasciate un commento o chiedete sul canale IRC #fedora-it
