Fedora Elections and Weather Applet

Just as everyone else SHOULD be doing....

Fedora Votes!
(thanks to whoever drew the artwork)

Go HERE to vote if you're a member of Fedora

With the election going on, I believe we'll have a great board elected to continue the progress Fedora is making. So do your part and VOTE NOW!

On the KDE side of things...

I spoke to one of our famous artists Pinheiro for a mockup of the Weather plasmoid. I'm sure he'll have some interesting ideas to cook up. It looks like I won't be able to get this thing in for KDE 4.1 (sigh). With no artwork (and I'm a terrible artist), it's best to leave this in playground.

I plan on working on some other ions (data source engines) for other Free weather data sources soon if their licenses allow me to do so.

Calling other artists, anyone in the mood to write SVG weather icons? kthxbye Smiling

The Fedora 9 Release party and KDE

Well, a few days ago, I attended the release party for Fedora 9. There was a lot of people who showed up a few Red Hat folks who work on Fedora and packages. There were also a few users who showed up to try Fedora out for the first time. It was a big success! Thanks to all who came out

When I arrived, I was asked to demonstrate KDE for the audience. Seeing that I don't have KDE 4.0.x and that I'm using trunk ('4.1') I showed them some features in 4.1 giving them notice of the bugs they were about to encounter. All and all, the demonstration went ok otherwise.

I have to say though, we have a lot of work to do for KDE 4.x to catch up with the GNOME folks as they have more things integrated together. Hopefully by a later KDE 4.x, we'll have more integration. We took a big risk in KDE 4.x but even though all the current pain, it will be for the better in the long run.

I'd like to also dispel FUD that I still keep hearing about KDE and Fedora. As you know, historically Red Hat/Fedora have been a GNOME shop, this remains true today, however, with Fedora 9, there is full KDE participation now. We have a KDE SIG group that maintains and charts KDE's course within Fedora. There is still some work to do to building more bridges, but I am glad to see Fedora reaching out to KDE as they have now.

Special thanks and greetings to: Andrew Overholt, Behdad Esfahbod and Brian Pepple for making the party a success! See you for Fedora 10 Smiling

More Cross-desktop collaborators and the eventual '1.0' release of the weather applet

Colaboration

I am pleasantly surprised to hear from Aaron Seigo and others that there has been more collaboration going on that most people might not know about. Learning that Qt 4.x now can use the Glib event loop gives us a lot of abilities to create glue between KDE and GNOME interfaces which is really encouraging.

Also happy to see other GNOME people such as Hubert Figuière and Rodrigo Moya are looking at more collaboration between our two teams. This can only be a Good Thing.

I personally look forward to working with other teams together to help us make the Desktop on Linux (and the other Freenixes too) grow.

I had a look at libgweather and wonder how to hook this into the weather engine but haven't examined the code yet. If it can provide similar data such as collecting current conditions as the ions do, maybe create an ion (data source plugin) to load libgweather and hook that in somehow.

Plasma Development

In the meantime, I spent a night of debugging to track down some new behaviours the Plasma Sprint has introduced. Needless to say, some of my code changes to fix the applet seem like ugly hacks but they might be part of a bug somewhere in the new API I hope. Now that I'm Plasma Ready(tm) again, I'm planning for a simple applet release in time for KDE 4.1 (for extragear).

Now, in previous postings I've talked about all sorts of wizbang features and things, but those are the goals of the project. This first version is going to have a 'button like' look, much like other simplistic applets. It will utilize the SVG skin theming only for now not icon theming. We don't have a free set of icons to use other then kweather's icons. Maybe this will make the Oxygen people cry and demand new icons Smiling

Since I'm going for simplistic right now, it will only display current conditions. Let's get something out the door that works. As for KDE 4.2, things should become more exciting.

It was important for Plasma to break the API and even if that slowed down Plasma development, this will give us a much better framework to work from.

Calling all cross-desktop developers! Let's make crossdesktop colaboration more important in Free/Libre Open Source

It's been a little while since I've last posted an entry. My own personal life has been busy and hasn't given me much time to work on code. That will change soon though Smiling

I post here today as a KDE developer and moderate in the support of cross-desktop collaboration and friendship. Myself and a fellow GNOME friend have created a channel on Freenode and irc.gnome.org (Gimpnet) called #freedesktop-cafe. The channel is designed to have GNOME and KDE (and other desktop camps) developers (and users too if you like) come together for casual (non-developer) chat and to help build friendships. It's not meant to be political. The channel relays its messages to both networks. I'd like to know what you all think.

This channel is not sponsored by either KDE or GNOME. I hope in future we can work together more, despite our language differences and technologies. You can't work with people if you aren't friends with them.

Sometimes, you just have to do it

You know, it's just in my nature. When someone falls, you help them up. When someone needs help you provide assistance. Well, the same goes in the online world. You see, ever since Aaron Seigo and Siraj Razick wrote up the CIA.vc applet, I sort of had a small crush for it. After watching it bitrot, stumble and cry for help. I thought it was time to make it smile and feel loved once again.

I bring you the updated CIA.vc applet. There are some small goals to come for this such as, adding a config dialog to display (or allow) you to type the CIA project you want to monitor and finally fix some of the rendering issues near the bottom of the plasmoid (if the current layout functionality in 4.0.x lets me).

Just remember, when you see code wallowing with sorrow and shame, cheer it up and make it grow and shine! Smiling

Happy New Year! And a little present

Well, the homestretch is near, I've had to dropped some functionality to get this finished for KDE 4.0.0. So, no Icons for this version. But, you can see It should replace most of the functionality kweather did. This applet does not support dropping onto the panel or If it does, it might not render correctly.

I decided to just leave the name 'Weather Applet' for generic reasons. Maybe the name will change for KDE 4.1 we'll see.

Next, I have to write a HOWTO for people to write ions (data source backends) to get other weather sources from your local country (if available).

If you know of any countries that provide XML data or freely available data, do let me know. I'd be happy to write a backend to add to this list Smiling

Here's a busy screenshot showing various places. Some of the data sources (ions) report warning/watch information. Only the Environment Canada one at this time provides this information.

Comments welcome, please note this is just for KDE 4.0.x, KDE 4.1 I will implement the features mentioned in previous blog postings. We just ran out of time folks Sad

Goals for the Weather Applet (I need a name for this) and testing KDE 4.0 post-Beta 3

Given the time constraints for KDE 4.0, I have decided to downgrade the functionality for the weather applet. In this release, my aim is to replace kweather functionality completely. This should be feesable to do for the 1.0 release.

Given that Plasma will likely have changes for KDE 4.1, It would make sense to hold off until more of the plumbing has settled down then all the eyecandy can be added in.

I gave KDE 4.0 post-Beta #3 (October 21nd build) a go last night. For the most part, I was able to use KDE functionally. Konqueror crashed a few times, but expected. Composite worked, exploding windows and all Smiling I could not log out or lock screen as it would deadlock X for some reason.

Given I've been ridiculed on IRC for complaining about KDE 4.0's release time/schedule, The best thing I can do is to look at what bugs that can be fixed which I can start looking at tonight.

I would note the Oxygen window decoration is nice however on LCD screens - gamma adjusted or not - it there is no contrast between white windows. I hope the theme will get gradients so that one could distinguish between different windows.

Ontario Linux Fest 2007 and WeatherEngine changes

Ontario Linux Fest 2007

I had a good time at Ontario Linux Fest 2007. This being the inaugural event there were some small annoyances like lack of plugs for laptops. They did have free WiFi and there was time for me to hack on the weatherengine while there. This conference has a mix of corporate and geek culture and slightly differs from OLS (Ottawa Linux Symposium) but it's likely to grow and evolve over time.

While there, I met Marcel Gagné who presented Aaron Seigo's slides on KDE 4.0 upcoming features, frameworks (he had to skip some of the developmental slides as the audience level didn't appear to be too technical). He also gave a demo of an October 12th build Plasma showing a few of the plasmoids and he demoed the new KDE 4 port of kickoff, raptor and Dolphin. He didn't show the sexy new Oxygen style or window decorations though Sad

Although Marcel mentioned Plasma was still in heavy development, apparently, people just weren't paying attention. During Q&A, there were two negative comments. One being, "I hope kicker is still there, the panel looks dumbed down" and the other comment was, "Can I turn all this bloat (referring to Plasma) off?".

With the blood boiling within me, I blurted out that kicker was going away because Plasma would be handling the panel now and to the other person I politely reminded them Plasma is still in heavy development and that things were changing rapidly.

I wish people wouldn't jump to conclusions and ridicule KDE/Qt as 'bloat' or criticize a project in such heavy development

I went to a few other talks/bofs and chatted with some CLUE (Canadian Linux Users Exchange) people about making sure we don't get evil things like DMCA in Canada. The conference was just one day and I won a Ruby pocket book (The prizes were on a first come first serve basis, so by the time I had won, that was the last prize left. When it comes to script languages, I'm a python guy Smiling

WeatherEngine changes

A night before, Aaron helped me fix up the weatherengine and ions to be fully asynchronous. This means the backend is even faster now and much more flexable. The BBC ion plugin should be able to be finished now. I have also begun a very preliminary C++ plasmoid but there is no screenshot worthy to display yet.

I showed off the weatherengine goodness to Marcel and he wanted that info (ooohs ahhs) for any weather plasmoid he'd use Smiling

Plasma Weather Engine update

While the Plasma APIs have been in flux (and is beginning to settle down now). I went about implement displaying the wind speed in metres per second as requested by a KDE person. It converts mph to m/s or km/h to m/s. This will become a configuration option once the applet code is started.

I haven't been able provide that screenshot of the applets yet Sad as mentioned above, things in Plasma have been going all over the place. There's a lot of regressions that are being worked out so I'm just focusing on the ions for now.

I will be going back to the BBC ion to see what can be changed. It's rather nasty in that parsing BBC's WAP/HTML they do not provide a static list of places whilst the other ions do have a list of places they can report weather from.

WeatherEngine now in KDE Trunk!

We had a Plasma meeting yesterday. One of the things discussed was to move the weather engine bits into KDE trunk. This is now done.

Richard Moore is planning on taking a look at a bug in the UKMET BBC datasource. Once that issue is fixed. I plan on finishing the ion. I will be adding to the Techbase Wiki information on how the dataengine works, how the data formatting should be done so that each ion can be used by anyone's own weather applets.

Richard has been busy hacking away on the Plasma JavaScript support bindings. I will be using these bindings to write the applet. It is possible this weekend you might get to see a screenshot of the weather applet displaying current conditions.

I plan to have the following 'screens' depending on the datasource (ion)

- Current conditions (Screen #1)
* Place information
* SVG (or PNG?) icon showing the current reported condition
* Temperature in your favourate metric (metric, imperial)
* Comfort Temperature: (Humidex/Heat Index, Windchill)
* Dewpoint Temperature
* Pressure (in inches or kilopascals)
* Pressure tendency (if available)
* Visibility (in kilometers or miles)
* Humidity
* Wind Speed (in kilometers or miles per hour)
* Wind Direction
* Wind Gust

This will contain the minimal current observations where available.

- 5 Day forecast (Screen #2, if available)
* Place information
* SVG (or PNG) image containing the expected weather condition for that period
* PNG/JPG/GIF image of the respective Weather agency (Credit requirements)
(top left side of applet)
* Short expected weather summary: Period, Condition expected, High Temp or Low Temp followed by
POP (Probability of Precipitation).
-I believe if the user clicks on a specific period we can make it display extended weather
forecast information (wind speed, etc) via some sort of visualization popup.
- For future, I will be also providing a rough gestimate of potential severe weather
(where available) such as CAPE (Convective Available Potential Energy), SI (Storm Index).
This is likely for 2.0 of the applet.

- Almanac Information/Seasonal Normals/Records (Screen #3, if available)
- Rises/Sets (if available)
* Sunrise/Set
* Moonrise/Set
- Normal temperatures for time of year (if available)
* High temperature (in metric or imperial)
* Low temperature
* Mean temperature
- Record weather (if available)
* Record High temperature
* Record Low temperature
* Record Rainfall
* Record Snowfall

- Miscellaneous Information (Screen #4, if available)
* UV Index
* UV scale (high, low, extreme, etc)

This is a lot of weather data. The idea is to have the weather applet cycle though these 'screens' on a timed interval, fading in or some other effects to transition between screens.

For configuring the applet, the user will be able to set time intervals for fetching updated information (on 30 minute intervals).

More on the configuration later.
