[edit] Rules

To ensure that the event runs properly, there are a few essential rules:

  • Only individuals may participate. Companies are excluded from the competition because of equity reasons.
  • If you have coded your app in a team and you win one of the prizes, your team has to designate one person as the winner.
  • Any number of apps can be submitted and elected as winners but, as communally agreed, there will be one prize per developer.
  • Entries must be available as executable or equivalent and your entry should include at least two screen shots/pictures and a brief description to take part in the election. Entries have to run on Maemo or Mer-based devices/platforms. Device ports have to work on informed hardware.
  • All applications, which are created and uploaded during the duration of the competition and do not violate any laws or copyright will take part in the election.
  • A new application, in the context of the competition, is one which has not been previously developed for the Maemo or Mer-based platform.
  • Ported applications are welcome, however only the work of porting will be considered (unless the original program is from the same developer and was developed or extended within the competition timeframe). These entries should include a description of work done during the porting process to enable the application to run on the platform.
  • Already released software must have a substantial upgrade from previous releases to qualify for entry to the 'Update' category. These entries should also include a list of changes the author has made to the previous version.
  • Coding competition entries marked as beginner will also automatically be entered into the beginners contest if they meet the following criteria: entries to the beginners competition should be the authors first released coding project(s) for the Maemo or Mer-based platforms, and must have been first released between the competition start and end dates.
  • Entries that are not stand alone software will have to include any libraries or files required to run, or they should be easily available via the normal repositories. Clear instructions will have to be provided. In the case of interpreters and emulators copyrighted files should not be included.
  • There will be a feature freeze on entries during the voting stage of the competition. Please limit your code changes to bug fix only for any competition entry release during this period, and this restriction should remain until the end of the vote.
  • Only users of maemo.org who are registered at the start of the competition and have at least 10 karma at the time of voting are entitled to vote.
  • There is no legal right to win.

[edit] Voting

Voting will run from February 16 through February 28 2017, 23:59 UTC

The voting frontend, the webinterface via which you enter your vote, is the same as for the Maemo Council elections. So you can establish an order among the participating applications indicating your preferences. Thereby, the first choice has the most impact. With following choices the impact gets less and less. The last choice has the least impact. Every voter has one vote / category.

[edit] Counting Votes

After the voting period has finished the votes are counted. The ranking order of participants is determined based on all valid votes.

The tool used for counting the votes is OpenSTV. We use OpenSTV version 1.6.1-1 which can be publicly downloaded from http://packages.debian.org/squeeze/openstv . The openstv executable used is extracted from the *.deb package.

For each category, the ranking of candiates is determined individually.

As general "vote counting system" Fractional Transfer Single Transferable Vote (FTSTV) is used. FTSTV, however, does not provide a way for determining the order of participants out of the box.

For determining the ranking among the participating applications the following approach is used:

  • The winner is determined by running OpenSTV for one seat.
  • Subsequently, the second place is determined by running OpenSTV for two seats. Thereby, the winner from step 1 plus another participant will be elected. The newly added/elected participant is placed second.
  • For determining the third place, OpenSTV is run for three seats. The newly added/elected participant takes the third place.
  • This process is repeated until the number of seats reaches n-1 with n being the number of participants. The remaining participant not being added or elected yet takes the last place.

For automating this counting process the following script is used 

election=$1

tail -n 1 $election | sed 's/"//g'

>/tmp/result
for i in $(seq $(expr $(head -c 2 $election) - 1))
do
  openstv-run-election -r CsvReport -s $i FTSTV $election \
    | awk -F, '/Elected/ { print $1 }' \
    | while read w
        do if ! grep -q "$w" /tmp/result
          then
            echo $w >> /tmp/result
            break
          fi
        done
done
awk 'BEGIN { i = 1; } { print i, $0; i++; }' /tmp/result | sed 's/"//g'

This script should be saved to a file named "results" and can be called as follows: 

for i in *.blt; do sh results $i; done

Assuming the script + openstv-run-election are in the same directory as the result files (the *.blt files) for all categories and the current directory is this directory, this way of calling the script will perform the counting for all categories. The only thing that may be changed in the above script is the passage "openstv-run-election" for adding a proper path to the actual location of the OpenSTV executable, e.g., to point to "/usr/bin/openstv-run-election". Aside from this exception the script must not be changed at all.

However it is still possible to also do the vote counting manually using the described process. Vote counting process, OpenSTV version used, and counting script are all publicly available so everyone can perform the voting and verify the final official results.

[edit] App Developer Resources

[edit] Getting started with Maemo application development

##TODO

The Nokia Qt SDK is the official set of tools with everything needed to design and create applications for the N900. The development wiki is a great place to start, it contains lots of code examples and development guides. The "Windows Python and Qt in 30 mins" thread is a great PyQt tutorial for beginners and will have you coding your first app in minutes, and here's a tutorial from Linuxuser.co.uk.

The 'Developer' forum on maemo.org is an excellent resource to find answers and ask questions of your own.

[edit] FAQ

[edit] Spreading the word

[edit] Q: Which Twitter Hashtag to use for this Competition?

A: Please use #mccXVI

[edit] Application requirements

[edit] Q: It is obligatory to code in Qt?

A: No, it isn't, but it would make your life probably a lot easier because you will be able to reach more platforms. We encourage everyone to use Qt.

[edit] Q: It is obligatory to open source the code?

A: No, it isn't, but it highly encouraged. Community tends to give better votes for open sourced entry.

[edit] App/Application submission process

[edit] Q: Where to submit my application?

A: You can enter your application via talk.maemo.org thread available at http://talk.maemo.org/showthread.php?p=1517602 or by emailing your application to maemo-community<*at*>maemo<*dot*>org directly.


[edit] Q: Who selects the category of the application?

Will the developers select the category when they join the competition or will someone sort it into the correct category before the voting begins?

A: They will choose the category for their app, but everyone should keep an eye on that. Before the voting process starts we'll check if every app is in a reasonable category, so that it is not possible to cheat by choosing the category with the lowest competition.

[edit] Wishlist

If you would like to have an App, a Port, a Fix, a Hack or etc. but you can't code yourself, write it down here! Many devs are happy to get a new idea input. (Rom Manager was a proposal from year 2011).

application name short description features link to similar app or screenshots
AsteroidOS client for SFOS Developing a synchronization app between SFOS phones and AsteroidOS watches Several Bluetooth Low Energy profiles have already been implemented on the Android client and the watch's daemon, they would be great to have on a native SailfishOS client:
  • Notification profile
  • Weather profile
  • Media profile

Adding new profiles or improving them can also be a great contribution. Help and details can be found on the #asteroid IRC channel on freenode.

Bitcoin/Cryptocurrency wallet for SFOS A wallet for sending and receiving cryptocurrency Basic features:
  • Send and receive cryptocurrency.
  • Scan and display QR-codes of wallet addresses
  • Secure the wallet with a passphrase and encryption

Advanced:

  • multi cryptocurrency wallet and exchange between them using shapeshift or similar

Original Bitcoin wallet was done in Qt so you could get some help from there

Rom Manager A rom manager for emulators. Choose folders for roms of different systems.

Rom audition and fixing using Romcenter databases

Rom downloading.

Integration with most popular emulators (DrNokSnes, PicoDrive, ...)

Rom Gripper for Android.
GNU Backgammon port A port of GNU Backgammon to Maemo/N900 GNU Backgammon is a backgammon program with a really good AI and Maemo has no backgammon program.

Its GPL, uses GTK+ and has packages for Debian already.

Mumble for SFOS Porting Mumble written for N900 to SFOS Mumble is a low latency VOIP Server and a client. N900 or Maemo has a Mumble application which included a server. It would be nice to have a SailfishOS client for Mumble.
  • First of all Maemo application was written for X11 while SFOS one needs to be written for Wayland.
  • Its now new Qt version ( 4.5 -> 5.6(target))
  • It was suggested in #Mumble channel that its hard to port as most of the protobuff stuff needs to be written
  • A new app should be able to query the mumble protocol.

Alternate Suggestion:

  • An easy solution would be to write a PyQt app using the Mumble Python API.
Matrix client for SFOS Porting any Matrix client to SFOS - Riot is actually a nice example IMHO. Matrix is an open standard for interoperable, decentralised, real-time communication over IP. It can be used to power Instant Messaging, VoIP/WebRTC signalling, Internet of Things communication - or anywhere you need a standard HTTP API for publishing and subscribing to data whilst tracking the conversation history. Matrix’s initial goal is to fix the problem of fragmented IP communications: letting users message and call each other without having to care what app the other user is on - making it as easy as sending an email.
Ring client for SFOS Porting any existing Ring client to SFOS Ring is for the time being, the most promising privacy oriented chat/voice/share client, imho. I know it's still in beta phase, but it works really well on both Linux and Windows (haven't tried the others). Ideally this would be fully integrated into the system through Telepathy rather than a separate client.
Orrery for SFOS An open source amateur astronomy app The orrery program is a program to display stars, planets and other astronomical objects on devices running the Maemo 5 software suite.
Vevo videos on YTplayer implement the ability to watch Vevo videos on SFOS (YTplayer/LLSplayer/standalone app) Currently is not possibile to watch Vevo videos apart using browser cause it gives some kind of error. it would be nice to have a way to watch them in an app
strato hidrive a native app for the online-storage of hidrive. that already exists in android , but a native app would be better. features like: up- and downloads, automatic sync * google-app
Sail-harbour or jolla-radar A on the phone based standalone-leave-alone Suite, managing main feature of a phone through a web-frontend in a separate desktop. Connectivity: USB Networking, wlan, BT Networking.

Export: Filesystem,Controls,Settings,Screen,Internet
Frontend-features: Filebrowser, Mediaplayer (remote), Messaging, Calendar(manager), Gallery, Videoplayer, Accountmanagement, Screen remote, Backup&Restore.
complete description on jolla tjc

  • ajenti
  • Airdroid
  • KDE Konnect
  • Sailserver (native sailfish-app) minimalist concept like airdroid, apparently not maintained any more.
Subliminal messaging for SFOS A native SFOS app that displays text or images messages for a few milliseconds on a regular interval (every 5 seconds or so). Currently no such app exits for SFOS. It is good for learning something easily, positive auto-suggestions and the like. On Android, there are several apps. Example: Subliminal Messages Lite [6]
Cutespot Every platform needs some apps which everybody knows and a lot people needs, Cutespot(Spotify) is one of them. As can be seen herethere are enough bugs that needs to be squeezed. I hope with the attention from this competition the app will grow in towards a stable nice Sailfish app.

The topichere at TMO.

Tweetian Tweetian is a Twitter client which has some work to be done, but also a app that is important for the platform SailfishOS as it is almost the only native Twitter client. There are over 60 issues in Github which can use some time and investigation.
