For the uninitiated, a mind map is a graphical organization of ideas and concepts that can be used to facilitate the generation of ideas and the learning process. Mind mapping is done by connecting one idea to another with the aid of colors and images to tap both sides of our brains.
If you’re thinking of how you can start adsopting mind mapping in your learning or brainstorming needs, check out these 43 great examples of how mind maps can be made. This applet is kind of orthogonal to Lion Mail, but it's really interesting to see how easily we can share code between Plasma (and thus mobile devices) and "traditional" KDE applications.
Recently, the discussion whether to make KDE the default desktop on openSUSE has been raised. SUSE Linux, and openSUSE (its follow-up) have traditionally been very KDE-centric, many KDE developers ran SUSE, many inside Suse ran KDE, basically Suse was a KDE-centric distribution and all was fine. Also, over the last years, openSUSE moved further and further away from being the home to many people inside KDE, and the best distro you could choose when looking for a KDE-based desktop. The first step was making KDE not the default anymore, offering a list of options during installation. In any case, the development of openSUSE position towards KDE have lead to many people moving on to alternatives. Nowadays, Novell is trying to turn openSUSE into a project which is fully managed by the community.
An important point that many people here fail to realize that this is not asking for granting a special priviledge to KDE. From Lubos' email, it's pretty clear that the status quo is not OK for a large part of the active contributors to openSUSE. Vincent Untz, Board Member at the GNOME foundation (while acknowledging his bias) has proposed to do another vote on this particular issue.
Joe "Zonker" Brockmeier, community manager at Novell sees real value in not having a default, however.
Another important point for me is that only one such question ("What desktop do you want?") adds the requirement of domain knowledge.
Michael Löffler notes that only a relatively small part of the openSUSE users are new (about 6% according to the survey), and concludes that therefore, a default setting isn't all that important. The impression I get is that Joe Brockmeier wants to keep the status quo (no default, GNOME listed as first option) to not cause political discussion and disruption in the project, to keep people calm.
After Linuxtag had finished, a couple of gearheads went to Berlin Kreuzberg to grab some food and a drink in a quiet and not to crowded place. I'll be staying for another two days in Berlin, then pay a quick visit to Kim and the pets at home before I'm flying to Gran Canaria for an awesome summit. Update: Meanwhile, I had the honour to have Matthias Ettrich and Martin Konold (the two founders of KDE) sign the FLA.
I'm using a US keyboard layout on my machine, since that's the most hack-friendly one I can actually grok and type blindly on.
This week has brought me to Istanbul, to attend Senlik, which is a Turkish Linux conference organized by LKD, the Turkish Linux users group. The conference is hosted at Istanbul's Bilgi University, which is not purely technical but focuses on design and user interaction.
As someone just pointed out to me, I (or rather the organizers of this conference ;)) have picked the perfect time to visit Istanbul. On Wednesday, I'll spend the day at the Pardus office here in Istanbul, where we planned a workshop for the team. The coming days, I'll be a bit silent, as I'm taking the opportunity of being here with Kim to also relax a couple of days as well, something we didn't get to a lot lately. Some other bits that I fixed in Lion Mail include monitoring for changes in collection statistics (number of emails, number of unread ones), and writing out the changed information of an email back to Akonadi (or in less technical terms: marking an email as important, read, new or task now actually works). Also, I've done some UI cleanups in Lion Mail, the action icons are now only shown on hover, making for less clutter in the default view. Toma has been working on fetching information from microblogs into Akonadi (such a thing in akonadi language is called as "resource"). Now the team is up for a totally different, less collaborative and more competitive endeavour. I've been thinking about Google's Summer of Code program a bit, and since it's having its fifth birthday this year. It's good to see how this is managed by the Google staff as well, they're not just throwing money at us, they're actually putting a lot of effort into SoC, and it provides real, tangible and sustainable benefit for Free Software projects. The user wins as well, over the past year, we came to ship many of the things that have been done within Summer of Code project.
With an Akonadi sprint in Berlin coming up, I thought I'd write a couple of lines for those who are interested in some PIM stuff in Plasma.
There are a couple of things that need more work, either because I've not gotten around to it yet, or because I didn't find a good solution. The atmosphere is is really great, it's fantastic to discuss plans and their implementations with the iNdT folks (especially when the meeting table is not a table but a large swimming pool -- that definitely makes for fun and interesting digressions. Just a couple of days ago, we've upgraded qt-copy in KDE's SVN to the release candidate of Qt 4.5. Note to self: Just blog, don't ask Blauzahl if the picture is good enough, you can always fix it up latah! You'll need two functions then, slotresourceactivated(QUrl url), which might be as simple as just KRun(url) in order to open the file (or url), and slotsearch(), which runs the query on the the string from the search lineedit.
Networkmanager is a daemon that keeps track of lower level bits on computers that have changing network hardware. So one of my personal goals is to not make all those mistakes in the interface for networkmanager in KDE4.
The development platform is paying off, it proves to be a very extensible and future-proof platform, more and more applications are becoming available on Windows and Mac, KDE on OpenSolaris is getting closer to inclusion in the distribution, and we've seen KDE already available on FreeBSD. On the organisational side, this growth in the KDE community and the increased attention from both users and the wider Free Software community, has been balanced out by the launch of the KDE Forum and UserBase to improve communication across a wider community. Lesson learned: Check your facts before you publically dissect the inner workings of something that is as complex as powermanagement for a desktop system and that you're obviously not familiar enough with to judge whether this piece of software gets it right or not.
I'd also like to thank Matthew for his input on these matters, and I'm glad it's not as disheartening or dramatic as he tries to put it. This application was created to enable you to delete your files permanently.Want to delete your files easily?

Some people say Google Talk is nice because of its minimalistic design, but they coudn't use an Instant Messenger that doesn't have smileys and font customization. The reason why this has been argued to be more effective than the traditional method of learning (e.g. The variety of these examples only goes to show that there’s no one right way to create a mind map. He, Andras and a couple of other KDABians are splitting KMail into smaller components that combined make up an email client. Of course using the KMail widgets means, that it's only rather shallow integration between those two, you don't, for example, get the full Plasma theming or input models that are interesting for mobile devices. We've released a fantastic set of applications, a beautiful and organic desktop that enables the user to do a couple of things that were previously simply not possible in this form. It was in freeze for quite some time already, and there have been some reviews around on the net (most of them rather positive).
The rock-stable development platform that is KDE 4 supports this well, and has in itself gotten nice additions, polish and many fixes. When Novell bought SUSE Linux, and roughly at the same time Ximian, things started to change. At first, KDE was still on top of that list, at some point it was moved to the second place (which of course was done to reflected the alphabetical ordering). Quite some KDE developers I know, who have previously been avid SUSE users have reconsidered and are now running something else. I think this is a great opportunity, also for upstream communities to get more involved with a distribution, but of course it goes both ways.
In fact, it is asking for removing a special priviledge that makes many in the KDE community feel that KDE is treated unequally in openSUSE.
I think that's a very dangerous thing to do, because it might be interpreted as "We'll keep repeating the vote and changing the mechanism until the result suits us". In order to get as many people possible to install openSUSE, you need to make the installation process as simple as you possibly can. He points out "But limiting choice, in my opinion, isn't the best option - the best option here is to do a better job at informing new users.".
If that was the case, you should just not setup defaults at all, anywhere, and that would quickly show that it's impractical to not offer defaults. The question is fundamentally different from "what is your timezone?" for example, so for a complete dummy, it'll not be possible to make sure all questions are answered correctly.
That's his job, and it would work if the current situation didn't have major problems already.
The fiduciary licence aims at simplifying this process, by assigning the copyright to an entity as KDE e.V.
This time, however, I'm not mainly here for KDE, but for KDAB where I've started working in May.
In case you're getting errors, try replacing ISO_Level3_Shift with whatever "xev" reports as (keysym 0xff7e, Mode_switch) when you capture the Right Alt key with it (or map it to anything you like in the same way).
Depeche Mode, (and Pink Floyd) are probably among those bands who have been influential for most of electronic music we're listen to nowadays, and in my opinion, very rightfully so. I've been invited to this conference by some developers of Pardus Linux, which is a KDE-focused Turkish Linux distribution. I think that makes a great location for a Free Software conference, as the UI part (artwork and usability) are often seen as stepchilds in Free Software projects. Temperatures are at a mild 20 degrees C during the day, the sun is rather warm and nice, but it's not too hot like it becomes during the summer here in southern Europe. I'll be using this opportunity to learn more about Pardus Linux which has been continuously impressing me with its amazing level of integration between desktop and underlying operating system. And there's this long list of different things I still have to try while being here (turkish bath, Iskender kebap only being two of the items lined up. It's one of the things where pieces of a puzzle fall into place, since the changes being written back to Akonadi showed that also change notifications about those items actually work.
I've spent some cycles yesterday night to add support for this kind of data to the Akonadi dataengine in Plasma and finished this in the course of today.
Some Trolls from the Berlin office have come over to teach the PIMsters the necessary Foosball lessons. I thought it would be about time to congratulate the people at the Open Source Programs Office in Mountain View, especially Leslie, Cat, Tiff, Erica and all the others who I had the pleasure to meet at various occasions. In Plasma for example, there's the extenders that have been introduced with KDE 4.2 and has already become part of the core infrastructure.
Still there is something I've not completely sorted when displaying the applets in a list and expanding items in that listview (usually Lion Mail).
I've been flying in last Thursday from Amsterdam via Lisbon, where I already met some Trolls (Andreas (QGraphicsView), Marius (QItemViews) and Simon (QWebkit)). Marcel went through some parts of the network stack showing many parts that just aren't up to today's requirements anymore, and presents a solution that he's currently working on as part of his work for Intel. In unrelated news, Gökmen, one of the developers of Pardus Linux (a Turkish Linux distribution) has invited me to speak at a (more user-oriented) conference in Istanbul next month. The first run took pretty long, but after that, indexing doesn't get in the way anymore and also doesn't hurt performance noticably (i.e. The plugin system doesn't quite work for me at the moment, there's an issue that a factory class always returns the most generic of the visualization plugins, making the results in the view look a bit boring.
If you're done, you can merge your branch, for example using "git svn dcommit" (do check with "git log", "git show" and "git svn dcommit -n" first if everything worked OK). It's designed to do this dynamically, and exchange information about status with a user interface that acts as configuration UI and policy agent.
KDE 4.0 has marked for the KDE community a stable base to build a kick-ass desktop and applications on.
New applications written in Python have entered KDE, and scripting support for many applications is becoming available as well, in the form of services in Amarok and scripted Plasmoids for example.
The formation of the Community Working Group has worked out very well and has come far in smoothening out how we work together. My idea is, to provide a series of screencasts showing off different aspects of KDE technology. First of all, Matthew assumes that the setting "powersave" will actually use the powersave cpufreq governor.
I'm assuming that Matthew does know *his* stuff (his general points are pretty much all sensible). In fact, reading his blog, I'm now even more confident that we have something that is both, in its default setting a very sensible system to manage power consumption while not getting in the way of the user, and also very powerful for all those cases where machines are just a bit different -- so we're also set to deal with a great variety of systems and usecases. Find the "skin_name".xml file, where "skin_name" is the name of the skin, and open it using notepad or wordpad. I was particularly intrigued by Jos' KDE 4.3 screencast (the one you can see in the announcement page).


Is the direction we're taking really reflecting in the user experience, and do people out there value our approach, our ideas? Overall, the performance and polish has improved, resulting in a smooth and attractive user experience. Three years ago, some people inside Novell planned to ditch KDE, meaning to lay off all KDE personnel and move on with the GNOME desktop only. In all other cases, when there is a clear preference, it is selected as a default, sometimes not even offering the user an easy choice. Otherwise, nobody should waste others time with asking, it'll not be more than a lip-service.
This means not asking the user too many questions, and certainly not asking the user questions he or she cannot answer.
If growth of openSUSE is one of the project's goals, the question "Why are only 6% of our users newbies?" would actually be one of the first ones I'd ask myself. I've pointed out the problems for the end user, Lubos has pointed out the problems for the openSUSE-KDE community. We quickly decided that it would be a fine alternative to have food and drinks in the streets and celebrated with another couple of hundred people until late at the night. If you've contributed code to KDE (even if it's just a little), please drop by the KDE booth at Linuxtag and sign your copy of the FLA.
So Kim and I got ourselves two tickets when DM announced the tour they're holding right now, but got disappointed when they had to cancel the concert that was supposed to be held week in Düsseldorf, Germany (quite close to Nijmegen actually).
KDE is actually very strongly represented at this conference, thanks to the work of the gals and guys from Pardus, who are also wonderful hosts to me and Kim, who accompanies me to enjoy the city for a bit. I'm trying hard to make sure that people know that we're embracing designers as first class citizens in our community just like we embrace coders, documentation writers, translators, promo people and community management folks.
The upcoming version of Pardus, dubbed 2009 will be released this summer, and I can only recommend to check it out.
That means you flag an email as important, and other applets showing this email are reflecting that change as well. While there's a microblogging dataengine already, storing the data in Akonadi makes a lot of sense, as it caches the information and makes it easily available to all kinds of apps (not just Plasmoids). And while I had initially been bragging about my skills (I'm unbeaten Foosball champion in the KDE e.V. There are actually quite some people active within KDE on a regular basis that have found their way into KDE through the Summer of Code programme. Rob Scheepmakers is the guy behind extenders, and has since then maintained the codebase and improved it further. Fetching of all the lists and content from Akonadi happens fully a asynchronous, which is a big, big plus if we want to keep the UI responsive.
The issue is basically that we're not dealing with email data but with URLs that deliver us one content type or the other.
After a good flight (I got four free seats in a row, which translated to "lie down and sleep as much as you can" to me), we arrived in warm and sunny Brazil. I'm happily accepting that invitation, so if you're in Istanbul on April 17 and 18, make sure you drop by. Roger had hooked me up with Michael (who had, the night before also Jos had the pleasure to be Michael's guest). Settings for wired and wireless start to work, as in "at least three persons on this Planet have ever been able to connect to a wireless network using it". The current activity in terms of commits to the KDE's SVN, the ongoing bug frenzy and general polishing of KDE4 desktop and apps is amazing. The wide acceptance of the Code of Conduct is another successful chapter in improving the collaboration. I've now mostly sorted out the technicalities and concepts, so I started recording some test screencasts. From my measurements, however, facts are: a) KWin with compositing enabled does hardly spend "a significant proportion of the time on the GPU". Unfortunately his arguments in the light of powerdevil's actual implementation are all strawmen. Such a screencast always gives a bit of a personal feeling and it shows what other people do with the software were working on, often it reveals new and cool and useful features, it did to me.
The request to make KDE the default on openSUSE is by far the most popular entry (second most popular following up at 175 net proponents). That happened relatively short after Novell had bought both Suse and Ximian, it has been said that those events are closely connected. In this case, however, while KDE is the clear choice in the openSUSE community, it is not treated the same like in other cases.
While a user survey does have a lot of value, only surveying, and then not following up on the results risks credibility.
This is the reason why almost every operating system out there has chosen default settings. Sure, it's a chicken-egg problem, the approach to this kind of question is essential to growth, however. It should be clear that this subject is not as easy as "We don't want to alienate the GNOME developers, so we'll keep the status quo".
As you can easily see on the photos, people were more than colourful, and it was a very friendly, laid back and fun event Linuxtag itself was quite good, I was mostly there representing KDAB, but got some FLAs signed and also held a presentation on using KDE 4 on laptops and netbooks.
I, or our friends from the FSFE (or Ade :-)) can explain to you in more detail what it means, and why it's important to sign it if you're still unsure. Today is the Sonisphere Metal festival, with koRn, Slipknot and as headliner Metallica playing. What I did is to modify my keymap slightly, so that I can use the Right ALT key (ALT Gr on some keyboards), and get the correct character just by typing Right ALT + a for example to get an ä). Dave Gahan, their charismatic singer had to undergo a cancer surgery to remove a malignant tumor in his bladder. The grand scheme is I think that KDE is moving from being a Free Software project to becoming a Free Culture project. The nargile causes a bit of a "light" feeling in the head, I figure it's mostly caused by an increased amount of Oxygen reaching your brain. Checking the mimetype of some dropped URL and doing something sensible with it is something I didn't get to work nicely yet. First and foremost, I don't want to request full folders of emails (a couple of thousand emails in the common case) only to throw 99.9% of them away. It's about 30 degrees here, and it's spot on summer (spot on winter would mean 26 degrees C, since Recife is only 8 degrees south of the equator).
It's basically supposed to be a "more than full" replacement for NetworkManager, which is very complicated in its design and often very slow in its use. Also, the results I got from Nepomuk and Strigi where quite OK, even when limiting the search to only 5 seconds (which makes the first results display a lot quicker as well).
Also, displaying them at different sizes can reveal or hide some information, which is definitely useful and makes the user interface a lot more flexible. It consisted of 25 patches, some larger (implementing a new feature), some smaller, cleanups, but also some patches I wanted to keep separate for easier reference and review.
It has UI glitches, it's not nicely streamlined for workflows we have in mind, the configuration interfaces are no beauty yet, and it has bugs, lots of it.
Applications such as Dolphin, Gwenview and Okular are mature tools, powerful and userfriendly at the same time, speaking for the KDE4. The CPU governor in use though is not the powersave governor, but the "conservative" governor, which indeed is an "ondemand" governor, meaning it gives you the extra needed CPU power when you ask for it.
Since I've been working on Lion Mail, I've got some ideas how this stuff relates to mobile devices, and I was also eager to give the akonadi port of KMail a shot. Over the next months it will come with many of the Linux and BSD systems so an even wider range (say those that stick to standard distro packages) will give it a try, and probably also many people that haven't used KDE, or Free Desktop systems before -- many of them attracted by the Appeal and Freedom that KDE - The Software and KDE - The Community provides.
The community, and many people at SUSE have made clear that they wouldn't accept this decision which eventually lead to Novell backpedallling and starting to "live with KDE". Instead, GNOME is given a priviledge that a preference must be explicitly expressed here, and this priviledge, to my knowledge, is not given to any other openSUSE component. Default settings for a webbrowser (what appp is used to open links?), default options for ui-specific settings (colors, theming, for example).
Especially if you're targeting new users to the Free Desktop, the complexity of switching to Free is already so high that adding another mandatory choice is only making it more difficult to install openSUSE. For all of them, not choosing a default option means increasing the entry barrier to openSUSE.
It could well be that the number of new users is only 5% because openSUSE is hard to install, because there's no default choice, no clear support and no distinct identity. Actually, I would not at all be surprised if the majority of GNOME-on-openSUSE developers would just see this step as catering to the largest user group.
I think I struck a good balance between technical background of power management related issues and things that are relevant to those who want to use KDE on those devices, and just want things to work (and possibly understand why they don't in some cases). When relicensing code of someone else, we're bound to pretty strict rules, all has to happen within the principles of Free Software. We'll also be bringing a stack of FLA forms to the Gran Canaria Desktop summit in a bit more than a week's time, so grab your chance, and protect your and our Freedom!
Quite some KDE people are working for KDAB (in fact it was founded by Kalle, one of the first "gearheads"). I used to a really like Metallica, I actually saw one of their concerts of the "Nowehere else to roam" Tour in the early nineties.
The 5 key already has € printed on it, so I'm using Right ALT + 5 to type the Euro sign. After all, 'only code' is not enough to conquer the world and make Free Software the default on most people's machines. We'll be looking at how we can improve the flow of code upstream, and what issues the Pardus developers are facing when interacting with KDE, both code-wise and community-wise. It'll also be a lot easier to query the information, for two reasons: The way you retrieve data from Akonadi is largely unified.
Lion Mail can load various collections, and handle them as independant applets or groups of applets on the desktop. That means that I need some way to query "8 news unread emails from all folders" or "all emails flagged important from imap folders private, work", "emails tagged 'petting zoo'", "8 latest emails from Artur, Wade and George (Yes, you George!)".
ConnMan is designed to make it easy to build a UI on top of it, which is good news for people like me, having worked on the NetworkManager plasmoids UI bits. He put me to bed after a marathon of something close to 40 hours without a bed (but the occasional 1-hour-naps on the plane). I didn't want to commit it to KDE's SVN as one huge commit, but also not as 25, with a lot of those smaller ones that were more the "savegame" type of commit you do once in a while to easily get back to a "working state" when you're about to break things or experiment. I personally didn't really like networkmanager's behaviour in the past, found it too random, too much getting in the way. With KDEnlive and Amarok 2.0 as their first KDE4 version, we see the more complex applications coming up. As its name says, it's slightly more conservative than the ondemand governor when scaling up.
I gave a talk this morning, which I found quite interesting myself (that's at least one person). Till and Kevin gave me some pointers where to begin, and I hacked up a small demo that shows how these components work inside Plasma.
The general idea is, offer good default that suits the largest possible group of users in order to minimize the "total setup time" all users combined have to invest. The general net-effect is that some drop-out during installation because it takes too long, is to complicated and requires domain- or expert-knowledge. It might even have a positive net-effect by making people try harder when they see that the default choice is actually a reflection of what the majority of users want, not a seemingly random decision by executives. After my own talk, I attended Will Stephenson's talk who put his salty fingers into some wounds we still have with KDE 4, and which are a problem for many user's experience with the desktop. I'm not really firm on legal grounds, so I'll invoke my fellow board member, Nijmegenaar and the new coordinator of the FSFE's Freedom Task Force (congrats!) to explain those details.
There's definitely a lot of interest to work closer together with KDE as an upstream community, and often it's just a matter of encouraging people to apply for an SVN account and start committing. Loading an email from Akonadi works nearly the same as fetching Contact data, or in this case entries in a microblog. Something I wanted to start using on my desktop machine yesterday so I can suspend it without needing to unlock it first. I think there are still a couple of days left until the deadline, so maybe someone comes up with a good proposal.
Upon dragging an email, you get a nice large-ish email icon attached to your mouse cursor, and when you drop the email onto the desktop, it's created from the akonadi URL, and loads its content from there.
While I was at first rather sceptical, thinking "Now that NetworkManager actually starts to behave like I want it to, it's being replaced, oh noooooo!", Marcel's managed to convince me that the way forward he's proposing is actually very sensible. Networkmanager 0.7 is better in that regard, it doesn't drop my connection all the time for a start, it stays online while you log out and operates mostly within the bounds of what I deem sane.
We're trying to have a first working version out within the next couple of months, hopefully in time for the distros that ship in spring.
On the workspace side, new UI technology has matured, KWin's compositing and Plasma give you a very smooth ride as well.
I'd invite Matthew or everybody else to provide additional data points so we can improve our default setting to optimize its behaviour further.) Users can of course easily check this themselves.
I've talked about how to get KDE on a mobile device, starting with an explanation of the software stack and how those parts related to platform independence, moving to technical challenges when turning a desktop system into a mobile system (covering things like screen resolution and pixel density, input mechanism and the more limited hardware you usually find on mobile and embedded devices).
It took me one late night hacking session until I had a partly working folder and message list in a Plasma applet.


The best way to accommodate for a healthy community is not avoiding politics at all costs, the best way is showing a strong sense of fairness and creating a system where success (for example expressed in terms of the default choice during installation) is based on measurable vectors, in this case popularity among users.
Besides the fact that not all of our cool technologies haven't yet shown their full potential to the users, Will made a good point that we're kind of sticking our heads into the sand when it comes to a really good web experience when using KDE.
That means that we have our morning coffee on IRC and jabber, and that most of the people are working from home.
I can help a bit by giving feedback for a draft, so you can still get it into good shape before the deadline. Eventually, the user should be able to just drag an email from her favourite email client (Mailody for sure, it's the first app to use Akonadi for email) onto Plasma, and maybe the other way round as well. The other side of the problem is of course that the display in Lion Mail itself doesn't do any kind of sorting at the moment.
Will Stephenson will probably concur as he sees actual documentation, as he's been the "sucker" who took on the work going through large parts of NetworkManager's source code to find out how to write a UI for it.
Git will instruct you to do what's needed, changing a log message, possibly solving a conflict. So the applet won't ship with KDE 4.2 we're planning to release it individually so you (or your distro) can grab it in the meantime. It offers a flash player, so it makes the content accessible very easily, but you can also view the Ogg Video version of the file, so it's equally accessible for those preferring a Free format. The "powersave" performance profile does more than just switching the cpufreq governor, it can also control your display's power consumption (and in the future probably even disable animations all over the place so you don't loose any of these CPU cycles for eye-candy). Run powertop with compositing on, measure your CPU consumption, switch it off (alt+shift+f12), measure again, compare.
Make your offering the most popular by gaining the most users, and you become the default choice. I agree that we can do much better, and that we need to do something about Konqueror (or our default web browser, anyway) not being able to render many web pages people out there in the real world use.
There is this odd group in Berlin who found that an office would be a cool thing to have, and that it's best situated in Kreuzberg, one of the more fun parts of the city.
Since they've let the recording industry instrumentalize Metallica to fight against sharing music, I'm having issues with the band's politics. There's relatively little in the way of fast food, but many different options in Turkish food. The Lion Mail applet groups emails into collections and displays them in a configurable listview, either on the desktop or as popup applet in the panel. I figured that would be futile, since I'm using the "throw away 99.9% method" right now anyway.
Sandro opened the conference with being interrupted by a bunch of Brazilian dancers, I guess everybody was pretty much awake after the drums on dancing.
Let's just say "it could've been a more pleasant experience" ;-) So yeah, documentation on the interfaces is something critical if you want others to use your stuff.
I arrived in Kingston roughly two hours late because there had been some fuel leaking into the engine. Also followed talks myself (Will's to begin with, giving me a bit more insight into Solid's networkmanagement stuff, quite useful if you're hacking on that ;-)).
After getting up, I caught Kevin on IRC to help me with my confusion, and the problem why the folderlist worked, but the message list didn't show anything. The openFATE request, in practice, asks for removing this GNOME priviledge and fair treating of all openSUSE components. As I'm working with some people in Berlin, I'm plugging into the weekly catch-up-with-everybody meeting via webcam and VOIP, which works quite well. Filing lawsuits against your fans is not the way to deal with them, or new and upcoming media and the failure of large parts of the music and recording industry in the adoption of the Internet. Vegetarian food options are just as numerous and good as non-veggie food (which is what I enjoy being a meat lover).
It possibly combines many of the interesting KDE4 technologies in a way that should be tangible for the user.
Then, there's the emailmessage applet that can be put in either panel or on the desktop, and reveils more information as you make it bigger.
The conference itself strikes a very nice balance between interesting talks, interesting conversations with interesting people, all that in a very relaxed environment. I had some interesting conversations yesterday with Rasterman, the founder of Enlightenment.
Apparently the crew didn't feel comfortable to fly my last hop without having it checked by two groups of engineers. We've already been thinking about possible improvements on the plasma mailing list, but with all the bug fixing around, we didn't get to tackle KRunner's UI in a way that makes it suitable to display results from a desktop search. Personally, I'm hoping, actually being confident that in 2009 we see the rise of new technologies such as Akonadi, Decibel, integrated desktop search and the semantic desktop.
If that's different on your machine, configure powerdevil to automatically switch off compositing.
Kevin advised me to uncomment some line, but when I looked at those line numbers, they were whitespace. It does give me that warm, fuzzy feeling of having actual social contact once in a while, while I still don't have anything to do with traffic jams, commuting and all that jazz. So tonight Metallica will be giving a concert within 5 minute walking distance from my home.
It takes place in a beach resort, basically a small village with a large swimming pool landscape in its center. Topics ranged from resolution-independant interfaces to release policy, filesystem hierarchies and how that works for users and of course more mundane subjects like "cocktails served in coconuts". So I started writing an applet for Plasma, since nobody seems to have done this yet and called it Crystal, since that's a cool name.
I've chosen a relatively liberal license so the screencasts are easy to redistribute and use in other materials. If you're findings vary from mine, let me know and we can further improve powerdevil's set of policies. Kreuzberg, where our Berlin office is located, is a great place for an office, it's very easy to reach, there's plenty of really good and inexpensive food around at the office, and many cocktail bars. It's really refreshing to see that a Free Software conference can attract women just in the same way. Part of the work will be integrating the bits that are already there, Decibel for real time communication, Nepomuk for search and indexing, Akonadi for PIM data, but also more "web-enabled technologies" such as GHNS, JOLIE and Attica to get information, content and also more interaction between users going.
The conference and hotel staff is making sure that everything is running smoothly and nobody seems to miss anything. Michael picked me up from the airport, got me some good food and put me to bed, which was needed after a long trip. Nepomuk actually made it very easy, with 300 lines of code (C++ even), I had a basic Plasma applet, including configuration to tweak the search, and the whole thing displaying results and opening those files.
Higher level concepts such as the Social Desktop will start to be integrated, and a wide variety of new and existing applications will make their way onto everyone's desktops and mobile devices.
After some minutes (and half of my morning coffee) I svn updated, recompiled and it just worked. It also makes a great place for hackathons, and my company is KDE-friendly enough to host regular meetings of all kinds.
Update: So turns out that my space-time continuum was out of balance when I wrote the above lines late last night.
The idea behind this is that you can drop interesting emails for reference onto desktop or panel, and throw them away when you don't need them. I've committed the applet yesterday to plasma's playground so others can have a look at this, too. Actually, I don't think there's a place that has hosted so many KDE sprints already, with certainly more to come. Something I find a bit confusing is that it offers two context menues, one on right click and one on left click. While not all we do is related to Free Software, much of the work I get in touch with is, and I think that's very cool.
Some friendly people pointed out that it is 2009, and after a quick check (we have clocks for that in Plasma), I have to concur. It should be straight-forward to set up Lion Mail so that it only shows you emails relevant to your current activity. Many aspects of the applet might change in the future, but it should be a good starting point to experiment with desktop search on the KDE4 desktop.
I'm using the fine Plasma notes applet to tell what's going on, although I'm forgetting to scroll in the beginning, and somewhere towards the end, please bear with me -- I guess that's some sort of digital stage fright. Working with and on Free Software is a great motivator for me, and it's good to see Free Software providing a viable business model.
I'm planning to also offer a safe way to trash an email, so you don't get to end up with the situation where you're distracted once by some spam email, Lion Mail and the Email Message Plasmoids act as some sort of intermittent email reader. Or in less abstract terms: When you're free, you should be notified and shown emails from work or when you're working on some project, to show emails relevant to that context. Then, Grandville, a friendly taxi driver picked me up to go by the University of the West Indies, to pick up Richard and Monika, two students attending CampKDE and some recording gear.
This also has to do with a limitation of the whole systray interface, which seems really outdated when looking at how we usually do these things in Plasma. So this week, I'll be hanging around at Linuxtag (we have a shared booth with the Qt Trolls, right next to the KDE booth). As a matter of fact, nm-applet uses the GNOME keyring, which reminds me that it would be nice at some point to share this functionality (i.e.
The different view modes, zooming functionality, tooltips, the cool selection mechanism (no ctrl-key!), shows how Dolphin integrates my USB stick and how you safely remove it, the Capacity indicator, the places, information, folders and terminal panels and how you can use them to make Dolphin fit your working habits.
On Saturday, I'll be presenting about KDE on laptops and netbooks, make sure you don't miss that talk. After Linuxtag, I'll be staying for a couple of days here in summery Berlin to catch up more on work-related things, and then I'll pay a brief visit to Kim, the cat and the chinchilla's only to depart to Gran Canaria.
I've picked it up, brushed a bit of bit-rot off of it and extended it to do everything I need, and a bit more. Right now when using nm-applet, I've two password stores that I need to unlock after login. Having a dataengine for this kind of stuff means that the data is very easily accessible for scripted applets, no special bindings for libraries in PIM or Akonadi are needed.
This means for example showing the number of unread emails in there, or something more fancy than that. It would ask the user to type in a WEP key (the long versions, often), didn't offer any help doing this, but made it made it harder. The Lion Mail applet show a list of emails, with various bits of metainformation hidden or shown. Points of discussion were mostly the ZUI, its usecases, how it's related to virtual desktops, and what we think we'd need to do to make it really usable.
You had to fill in the long HEX key twice, and both fields for that were password fields, so you can't even see what you're typing. We also talked a bit about documentation issues, developer documentation for libplasma, documentation for scripting Plasmoids, and user-oriented documentation.
It's free, it's lightweight, it's cross-platform, its codebase apparently is rather clean, in short it could very well fit into that mobile "niche" as use cases are more limited on those devices anyway.
Blauzahl told us that one problem of triaging Plasma bugs is that people often don't really know what's what and that the BugSquad in turn has a hard time to get useful bugreports. During the redesign that has taken place for KDE 4.2, we left some free space in its top center, arguing that it make be the place to put a desktop search box.
Clicking on the icon expands and collapses the header, clicking on the green expander shows and hides the body. Something that can easily be solved with an annotated screenshots (this is the one that needs a better version).
Sure enough the desktop search is fast enough (and I'm lazy enough) for me to replace most of the navigation-through-my-filesystem by simply typing the filename and choosing the correct file. It does a good job on the input side (especially given that the user doesn't use a keyboard but the touchscreen). First, it needs to work, a word processor, a spreadsheet application and a presentation program are the least I'd expect. Typically, you'll have Lion Mail sitting in your panel, if you click on it you'll see a popup just like the right applet in the screenshot.
First, support for WPA2 is lacking, that rules out access to the network at the university, and supposedly many others. If you're using the email applet on the desktop (bottom left in the screenshot), you can reveal more information by resizing it using applet's handle.
Then, it often reports that it has established a connection when it merely logged on to the access point, but didn't get an IP yet. Then, support for the most used standards, I know Girish is already working on getting OpenDocument support to work really well (absolutely critical IMO), but at some point, we'll also have to look at support for proprietary formats. Since you can often connect to accesspoints (even encrypted ones) but don't actually get an IP address, that information is often bogus and it can be quite annoying being told you're connected, while you're not. We certainly wouldn't like to burn credits by people that run into simple problems but just aren't able to find a solution to their problem or support in general (be it community support or commercial support). If you're planning to use it, hold your breath for a while, it's not ready for use at this point.
