KDE 4.4 Mail Misunderstanding Explained & Akregator Surprize

Filed under

I've gotten quite a few responses to my quickie look at KDE 4.4 under Mandriva written for this week's Distrowatch Weekly. One of which came from Aaron J. Seigo himself. I thought I might share some of what he said since several people expressed similar concerns on the topic here in comments. I also found one really super-duper neato new feature in Akegator in 4.4 that deserves a mention.

First to all, that wasn't meant to be a thorough review of KDE 4.4. I just wanted to talk about how easy it was to upgrade Mandriva and to install the KDE 4.4 packages and perhaps mention a few observations.

But one concern that several people besides myself have mentioned about KDE 4.4 PIM here on Tuxmachines was our understanding that our emails used in KDE PIM will be converted from our maildir format to database entries. This would make testing various distributions a bit more difficult. I know a little MySQL, but I really didn't want to be dumping and restoring a database every time I changed distributions.

But Seigo explains that our mail will not be converted and stored in a database. An index of our mail will be made and stored in a database table so that other applications could make use of it. Apparently, allowing for opening and accessing the mail in its current directory and format if need be - for example, as in a plasma widget on desktop monitoring for new mails. At least that's how I understood his explanation.

Well, instead of interpreting, I'm sure it would be alright to just post his exact words:

Actually, Akonadi doesn't change storage format (that wouldn't be a good move, really) but it centralizes access to the storage as well as provides uniform indexing. Right now, indexing systems aren't shared between mail/calendar/contact systems anyways, and Nepomuk allows the indexing to be shared between all desktop apps that use it. Akonadi itself provides access to the mails on disk so that it's safe for both, say, KMail and and a Plasma widget to be displaying the contents of the at the same time. So instead of being a heavy or "lock-in" style database, it's simply an access mechanism to storage formats that you and I are already (and will continue to) use.

I know this takes a load off my mind as I hope it does the others who expressed concern as well.


Now for the super-duper neato new feature in Akregator:

Akregator used to display polls and such as plain text, but with 4.3.2 polls rendered in radio-button or clickable format. That was kinda nice. But today I discovered something even better.

For Webmasters/bloggers/whoever that allow such, videos can now be watched right from Akregator. I don't know any real details, if only certain formats are supported and such, but I'm almost thinking they'd have to be oggs. I'm not sure if Flash videos would work as I disable all such in Konqueror/KDE. I'll check next time I see where someone embeds one in a feed.

Re: akonadi problems

On my experimental box, I'm running Mandriva's development version called Cooker (currently in Alpha state). When Cooker KDE packages were updated to KDE 4.40, akonadi wouldn't load, so kmail would terminate. Irritating. Started looking on the net, and in logs. Turned out the akonadi MySQL database config was incompatible with the MySQL packages in Cooker.

Some small changes in the akonadi mysql config file got it working.

Oh well, such is the life with alpha stuff.

Wish KDE would allow kmail to run without akonadi, for the time being.

re: akonadi problems

oh no. Another issue to be wary of. That won't be the only occurrence of similar in the coming months I'm afraid.

Yes, there should be some choice in the matter. A lot of folks would rather not have to have a database installed on their desktop.

Issues of space, resources, unknown future of mysql... that database indexing should be an option one can opt out of.

A look at Lutris – Open Gaming Platform for GNU/Linux

Lutris is quite the handy application I’ve discovered, that helps with organization and installation of games on GNU/Linux, even if they come from multiple sources. One of the project's goals is to support any game that runs on Linux regardless of whether it runs natively, through Wine, or other means. The main appeal of Lutris is that it provides an interface to manage all games installed on the machine regardless of source. While it is necessary to integrate the games in the application first, doing so is not super complicated. You may add local games right away by selecting them from the local system or visit the Lutris website to add games this way. Lutris simplifies nearly everything. Users can visit the list of support games on the Lutris website, choose to download and install the game (Note: If its a game that must be bought, you must own it first.) The website lists supported games and where you can acquire or download them. You can use filters on the site to display only free games, games of a genre, or use the built-in search to find games of interest quickly using it. Read more

GNOME Desktop: Flatpak and Random Wallpaper Gnome Extension

  • Flatpak in detail, part 2
    The first post in this series looked at runtimes and extensions. Here, we’ll look at how flatpak keeps the applications and runtimes on your system organized, with installations, repositories, branches, commits and deployments.
  • Flatpak – a history
    I’ve been working on Flatpak for almost 4 years now, and 1.0 is getting closer. I think it might be interesting at this point to take a retrospective look at the history of Flatpak.
  • Random Wallpaper Gnome Extension Changes Your Desktop Background With Images From Various Online Sources
    Random Wallpaper is an extension for Gnome Shell that can automatically fetch wallpapers from a multitude of online sources and set it as your desktop background. The automatic wallpaper changer comes with built-in support for downloading wallpapers from,,, as well as support for basic JSON APIs or files. The JSON support is in fact my favorite feature in Random Wallpaper. That's because thanks to it and the examples available on the Random Wallpaper GitHub Wiki, one can easily add Chromecast Images, NASA Picture of the day, Bing Picture of the day, and Google Earth View (Google Earth photos from a selection of around 1500 curated locations) as image sources.

KDE: QtPad, Celebrating 10 Years with KDE, GSoC 2018

  • QtPad - Modern Customizable Sticky Note App for Linux
    In this article, we'll focus on how to install and use QtPad on Ubuntu 18.04. Qtpad is a unique and highly customizable sticky note application written in Qt5 and Python3 tailored for Unix systems.
  • Celebrating 10 Years with KDE
    Of course I am using KDE software much longer. My first Linux distribution, SuSE 6.2 (the precursor to openSUSE), came with KDE 1.1.1 and was already released 19 years ago. But this post is not celebrating the years I am using KDE software. Exactly ten years ago, dear Albert committed my first contribution to KDE. A simple patch for a problem that looked obvious to fix, but waiting for someone to actually do the work. Not really understanding the consequences, it marks the start of my journey within the amazing KDE community.
  • GSoC 2018 – Coding Period (May 28th to June 18th): First Evaluation and Progress with LVM VG
    I got some problems during the last weeks of Google Summer of Code which made me deal with some challenges. One of these challenges was caused by a HD physical problem. I haven’t made a backup of some work and had to rework again in some parts of my code. As I already knew how to proceed, it was faster than the first time. I had to understand how the device loading process is made in Calamares to load a preview of the new LVM VG during its creation in Partition Page. I need to list it as a new storage device in this page and deal with the revert process. I’ve implemented some basic fixes and tried to improve it.
