Hackweek: Game Store

hackweek4

This week we had Hack Week event when everyone was welcome to use Innovation time on FOSS projects or even start the new one! I spent most of the time on hacking the Game Store, which I introduced in my previous blogpost. The package is now ready for you in the Build Service.

Simply use the following One Click Install files (openSUSE 11.0, openSUSE 11.1 and openSUSE Factory) or add the games repository and install the gamestore package manually. Game Store uses this repository to download the games, so you should stay subscribed to it after the installation too.

As a bonus I created a very simple One Click Install files catalog which imitates the Game Store look. It is available at gamestore.gk2.sk.

The screenshots for both versions (left Qt, right web) are here so you get the idea how it looks, but the best thing is to try it on your own! :-)

Big thanks go to randy-sk who helped me with harvesting of icons and screenshots of the games. I am already looking for your feedback! :-)

Game Store

I was adding some new packages to our games repository in openSUSE Build Service, when I realized that we have over 150 games at this one centralized place! Wouldn’t it be great if there was an application which would allow users to browse through games, filter them by genres or names, view the screenshots and read the information about the games? Players usings Windows can already use “Games for Windows” or “Steam” from Valve, but they also have to pay for the majority of the games. All games in our repository are free and just one click away! I started to hack an application with pretty concrete idea in my mind. You can look at the result of my efforts below (left Games for Windows, right Game Store):

games_for_windows

gamestore

As you can see, Game Store is at the moment quite immature Qt application (actually it is my first Qt app, so my Qt skills suck pretty much right now :-) ), but it is already able to load locally stored XML together with game icons, screenshots and descriptions. User can install new games (using our great One Click Install feature) and launch the installed ones. Later I want to add the ability to synchronize your games settings (configuration + saved games) with Game Store server, so you can have these on any computer and the server could create a hi-score charts for every supported game. There is a long way ahead to go, but I wanted to approach you very early, so you could be involved too. Even if you don’t speak C++ or Qt, you can help us with filling the missing descriptions, gathering game icons and screenshots. Just read the GameStore wiki page to get the idea what needs to be done or clone the git repo and start hacking right away! :-)

Thank you and I hope that GameStore will be a great addition to other openSUSE applications and tools we already have!

Update: See the next blogpost for more information.

Wireshark 1.2.0 with GeoIP support hits openSUSE Factory

A few days ago, the new stable 1.2 branch of Wireshark, the network protocol analyzer, was released to public. It contains many new features that has been added since 1.0. The most vivid are:

  • Wireshark now contains a nice new start page (Picture 1)
  • Display filters now do auto-completion (Picture 2)
  • Wireshark can lookup in GeoIP databases and also use OpenStreetMap (Picture 3)

wireshark-autocomplete

wireshark-map

The release contains also a lot of bugfixes, support for the new protocols and the new capture files. You can find more info in the release notes.

If you want to test GeoIP/OpenStreetMap integration in Wireshark, just follow these steps:

  1. install the latest wireshark and GeoIP packages from Factory: zypper install wireshark GeoIP libGeoIP1
  2. run the utility which was recently added to GeoIP package by Ludwig Nussel: geoip-fetch -a This will fetch the latest GeoIP data files including the GeoIPCity, which is 44MB large, so we don’t keep it in the package, but is necessary for this feature of wireshark.
  3. run wireshark and enable GeoIP: Edit -> Preferences -> Protocols -> IP -> check Enable GeoIP lookups
  4. trace some network traffic (probably the best is to access various websites in your browser)
  5. pick some packet and expand Internet Protocol from dissector, you will see a line similar to this one: [Destination GeoIP: Mountain View, CA, AS15169, 37.419201, -122.057404]
  6. go to Statistics -> Endpoints -> select IPv4 tab
  7. you’ll see IPv4 endpoints with Countries, Cities, Providers and Latitude/Longitude
  8. press Map button at the bottom of the dialog window
  9. browser with OpenStreetMap and embedded Endpoints will open (see Picture 3)
  10. you can also use new packet filters starting with the ip.geoip prefix (see Picture 2)

SVG-edit 2.1 released

Thanks to hard work of Jeff, Narendra, Vidar and me, we managed to create today a 2.1 release of SVG-edit. Interesting changes include:

  • tooltips for all UI elements
  • editing of fill, stroke and group opacity
  • selecting and moving elements
  • saving SVG file
  • adding end editing of text elements
  • context panel for tools
  • change rectangle radius
  • controlling of the editor with keyboard shortcuts

svg-edit-2.1

You can try the 2.1 branch here

Unfortunately the editor still has some problems when embedded into Google Wave, but now that Vidar received his invitation, I hope we’ll be able to fix it sooner. :-) We are also already cooking new features for 2.2 so stay tuned!

Opera 10 with Opera Unite in openSUSE Factory

operaunite

Opera Software unveiled today the new Opera build with a technology called Opera Unite. I updated the package in openSUSE Factory Non-OSS repository, so you can try it out. Factory package can be installed on older openSUSE releases too, because they are not built against particular libraries.

You are probably wondering what exactly is Unite? Simply put, it is a cloud architecture, where cloud nodes are computers of the individual users or more specifically Opera instances running on them. More marketing-friendly citation from Unite FAQ says:

“Opera Unite is a form of collaboration technology that allows you to share data such as files or photos with other users, directly from your computer . You can also communicate directly with others by hosting chat sessions or posting notes. The technology behind Opera Unite uses a compact server inside the Opera desktop browser to share data and services. With Opera Unite, there is no need to waste time uploading content you want to share. You share the content directly from your computer rather than loading it and sharing it through a third-party server.”

Folks at Opera also created this instruction video to help you get started. Even more information can be found in an introduction from developers and Unite User Guide.

If you want to know how this technology works under the hood or you are willing to create plug-ins (or so called Unite Services) I recommend reading Developer’s Primer.

That’s it! Go ahead and try it out! Also let me know what you think of it in your comments … :-)
