I believe it was the QtContacts Tracker team who requested this feature. When they have to unset the value of a resource’s property and at the same time set a bunch of other properties, they need to use a DELETE statement upfront an INSERT OR REPLACE. The DELETE increases the amount of queries and introduces a SQL SELECT internally for solving the SPARQL DELETE’s WHERE.

Instead of that they wanted a way to express this in the INSERT OR REPLACE, and that way gain a bit of performance. Today I implemented this.

So let’s say we start with:

INSERT { <subject> a nie:InformationElement ; nie:title 'test' }

And then we replace the nie:title:

INSERT OR REPLACE { <subject> nie:title 'new test' }

Then of course we get ‘new test’ for the nie:title of the resource:

SELECT ?title { <subject> nie:title ?title }

Then let’s say we want to unset the nie:title, we can either use:

DELETE { <subject> nie:title ?title } WHERE { <subject> nie:title ?title }

or we can now also use this (and avoid an extra internal SQL SELECT to solve the SPARQL DELETE’s WHERE):

INSERT OR REPLACE { <subject> nie:title null }

For multi value properties will a null object in INSERT OR REPLACE results in a reset of the entire list of objects. There is still a SQL SELECT happening internally to get the so called old values, but that one is sort of unavoidable and is also used by a normal DELETE. I hope this feature helps the QtContacts Tracker team gain performance for their contact synchronization use cases.

You can find this in a branch, it might take some time before it reaches master as most of the Tracker team is at the Berlin Desktop Summit; it must be reviewed, of course. Since it doesn’t really change any of the existing APIs, as it only adds a feature, we might also bring it to 0.10. Although now that we started with 0.11, I think it probably belongs in 0.11 only. Distributions should probably just upgrade, wait for the new features until they decide to bump the version of their packages, or backport features themselves.

Apple’s iOS will continue its attack on the mobile computing market, skimming (or carving as the case may be) profits from the phone business to sustain its ultimate target of reclaiming the computing universe..

Read on.

Online retailer Indiaplaza has listed the Nokia N9 on its website, with an expected availability date of October 2011. They’ve even gone on to list the price at a cool Rs. 32,368 which translates to a little over 700$. There is no word on whether this is the price for the 16 GB version or the 64 GB black variant.

But before you get your hopes up, for all we know the Indiaplaza page might just be a placeholder or something they’ve put up to draw more visitors. A quick query on Twitter told me that Indiaplaza’s reputation isn’t right up there with the best, so take this with a pinch of salt.

That being said, the N9 India page does say that the device will have manufacturer’s warranty and that means Indiaplaza will not be importing and selling the N9 on their own, but officially via Nokia.

The markets for the N9 have increased since the initial 23 country announcement and we’ve had reason to suspect that the N9 might be coming to India. The N900 came to India very late in the product’s life cycle, here’s hoping Nokia won’t make the same mistake twice.

Thanks for the tip, Avinash Shenoy.

[Update: It seems that the N9 has disappeared from India Plaza's website. So much for that].

Here's the second part of our mock-up collection for gPodder's QML UI (part 1 here). Let's start off with two more recent designs: One for the bottom media player and the "tab" to pull it up (the tab would always be visible while something is playing) and the other for the episode actions, which is something that I though would be good to have in addition to the context menu - the episode actions will put the most important actions (download, delete, play, stream, shownotes) into view when an episode is selected from the list:


Next up are two more of these green-ish mock-ups, where one has a different style of playback control buttons for the audio player widget, and the other one is an example of how the settings view could look like in the new style (again, this was before any of the Harmattan UI style guidelines have been published, so the design is very unique and doesn't take into account the availability of Qt Components yet):


And finally, here is a mock-up of a possible "Summary" view, summarizing what's new and also suggesting some new podcasts that might be interesting for you, based on existing subscriptions. This is not implemented yet, but it could be added at some point with a more deeper integration with gpodder.net, which already provides podcast suggestions and a tag-based podcast directory:


Thanks for your interest, and stay tuned for some updates regarding gPodder itself (for N8x0 users, N900 users and N950/N9 users as well) in the next days!

The popular and perhaps the best Facebook client for Symbian devices, fMobi is now available for the Nokia N900 as well. The full featured client packs in all the Facebook functionality that you would want like notifications, access to the news feeds, messages and even chat.

It features:

• News feed
• Chat
• Profile
• User info
• Messages
• Check In / Places
• Sound notifications
• Top Friends
• Liked Pages
• Groups
• Events
• Commenting / Liking
• View comments / likes
• Albums / Photos
• Notifications
• Landscape / Portrait
• Black / White theme

fMobi on the N900 (Maemo 5) comes with the chat functionality disabled out of the box, and because this is the first release there might be some connection popup issues if you don’t have a network connection and you enable chat. You can give feedback here, and download the .deb fMobi file for the N900 from this link.

That’s not all, here is something for you N950 and prospective N9 owners, fMobi is also coming to MeeGo soon.

Like many, I'm currently in Berlin for Desktop Summit, the combined conference of the GNOME and KDE communities. It is a lot of fun to see all the familiar faces, and talk about the different projects going on!

Now, one of the things I've talked about with people is NoFlo, my new tool that brings Flow-Based Programming to Node.js. What is that? Wikipedia explains:

Flow-based programming (FBP) is a programming paradigm that defines applications as networks of "black box" processes, which exchange data across predefined connections by message passing, where the connections are specified externally to the processes. These black box processes can be reconnected endlessly to form different applications without having to be changed internally. FBP is thus naturally component-oriented.

Basically the idea here is to simplify managing the control flow of software: what data goes where, what happens then, etc. with the goal of making software more understandable. With NoFlo you can go and peek under the hood of a running piece of software, see where data is going to, and even rewire some connections if you want to.

The project is still in reasonably early stages, but it is already used in at least one real-life deployment. Here are some sneak peeks:

:

If you're interested, follow the progress on my GitHub repo, or subscribe to the Flow-Based Programming mailing list.

In the spirit of Desktop Summit, it would be interesting to talk how these workflows would fit into the concept of a free software desktop.
