New Freestyle Competition: X-Style

On 2. Mai 2013, in IUF, Quelle: IUF, Unicycling, by Thomas Gossmann

X-Style

Got a cool Trick? Show it!

Felix and gossi are developing a new competition for freestylers. It’s all about skills, neither dismounts nor presentation are judged. This creates space for new, unfinished, risky and unsafe skills, which are just too fresh to show in a freestyle competition. Other riders should get inspired instantly. This new discipline finally allows to show off those skills in competition.

New skills? Old skills in new variations? Show some extraordinary skills in new and unseen combinations, aiming the highest possible niveau. Not the Hopping on Wheel everybody knows, but the Hopping on Wheel where arms touch the tire and feet grab the seat. Surprise the audience, so their minds are still blown away two hours after the competition has finished.

Each rider got 2 minutes for his run. Dismounts and mistakes are ignored. Each participant is rider and judge at the same time.

As the competition is still under development, we need many great ideas.

X-Style at Recent Conventions

We are happy to announce, X-Style is present at two major freestyle comptitions in may:

  1. Eurocycle (9. – 12.): X-Style will run on Sat, 11th during 17.30 and 20.00
  2. German Gymnastics Festival (18. – 25.): X-Style will run on Sun, 19. starting at 19.30

We hope many of you take the opportunity to hit the stage on these conventions. It would be really nice of you to send us an email, so we can better plan this (thomas.gossmann@unicycling.org).

X-Style in America

We are also happy to say, that Dave (main organizer of NAUCC) is committed to have this competition at NAUCC, too. At the moment they are looking for a proper location and timeslot. If you are dared to X-Style as we are and going to NAUCC, please support them with that competition, they are looking for a helping hand, too.

X-Style in your Location?

In your own club? Next unicycle meetup? Next competition? Just send the organizers an email, you would like to have X-Style there (I just did this myself by sending an email to Dave). Or organize it on your own, it’s very simple. We have everything prepared for you. Documents are in the IUF Cloud.

Further Development of X-Style

Although this is the first public release of X-Style, we are very much committed to this type of competition. You can expect that we are spreading X-Style to the rest of the world. The early feedback we gathered was very positive and will drive us through our journey.

Love Unicycling and its People

Actually, this is part of my personal story with X-Style. I send an email to Matthias Gauler (artistic organizer for Eurocycle) and asked him whether we can try X-Style there. Long forgotten about the email I send, I got the reply with the overwhelming news, they were able to free a slot for X-Style during Prime Time!

Second is my email conversation with Dave (NAUCC organizer) about adding X-Style to NAUCC. I had a bunch of emails back and forth and since the first email he showed very high commitment to X-Style with questions about what’s the proper way to put X-Style on schedule and about the competition and unicycling itself.

Basically, my emails were too late for both conventions to properly plan it. However both managed to include X-Style in their conventions to give an ear for new ideas and developments from riders. That’s the commitment we need for unicycling, to drive the sport, to develop it, to grow it. Thanks both for that.

X-Style

Got a cool Trick? Show it!

Felix und gossi entwickeln einen neuen Wettkampf für Freestyler. Hier zählen die gestandenen Tricks, nicht die Abstiege oder Präsentation. Das bietet Raum für neue, unfertige, risikoreiche und unsichere Tricks, die einfach noch zu frisch für den Freestyle Wettkampf sind. Andere Fahrer sollen davon inspiriert werden. Diese neue Disziplin ermöglicht es endlich die Tricks, die am meisten Spaß machen, in einem Wettkampf zu zeigen.

Neue Tricks? Alte Tricks in neuen Versionen? Zeigt ausgefallene Tricks in neuen Kombinationen oder auf hohem Niveau. Nicht das Wheel-Hopping, das eh schon jeder kennt, sondern das Wheel-Hopping, bei dem die Arme den Reifen und die Füße den Sattel halten. Das Publikum will überrascht werden und auch 2 Stunden nach dem Wettkampf noch immer staunen.

Jeder Fahrer hat für seinen Run 2 Minuten Zeit. Es zählen nur gestandene Tricks, Abstiege und Fehler werden ignoriert. Jeder Teilnehmer ist zugleich Fahrer und Judge.

Der Wettkampf ist noch in Entwicklung und wir brauchen noch viele, gute Ideen.

X-Style an Wettkämpfen

Wir freuen uns jetzt verkünden zu können, dass wir X-Style an 2 großen Freestyle Wettkämpfen im Mai testen werden. Zuerst an der Eurocycle (9. - 12. Mai) und findet zur Prime Time am Sa, 11.5. zwischen 17.30 und 20.00 statt. Eine Woche später am Turnfest (18. - 25. Mai) findet X-Style am So, 19.5. um 19.30 statt. Schon jetzt könnt ihr mit uns wilde Diskussionen führen und euch am besten gleich für den Wettkampf anmelden. Es wird auf jeden Fall eine Menge Spaß. Schreibt uns zur besseren Planung eine Email, an welchem Wettkampf ihr X-Style fahren wollt, an: gossi@einradfahren.de

Ihr wollt X-Style selbst ausprobieren?

Im eigenen Verein, auf dem nächsten Einradtag, Freestyle Treffen oder auf dem nächsten Wettkampf? Schreibt den Verantwortlichen eine Email, dass ihr das gerne dort ausprobieren wollt oder organisiert es selbst, es ist kinderleicht. Dafür haben wir alles schon vorbereitet. In der IUF Cloud gibt es dazu alle nötigen Dokumente.

Smiling Faces Unicycling Artists

Ein Freestyle Video. Viel Spaß beim anschauen.

When people talk about Unicycle Freestyle, most do it with “aww, that’s that girly thing on a unicycle” or “it’s like figure skating on a unicycle”. What if somebody asks a little deeper, like “which are the athletic components of freestyle?”. I bet, we get as much different answers as we get replies to that question. When it comes to developing the sport, a deep understanding of the working subject is indispensable. If not, everthing beeing worked on will fail and it’s just a matter of time until this timebomb will collapse. This article should give an introduction with the inner sights and should help people to understand Unicycle Freestyle.

Discipline vs. Competition

To make Freestyle even less understandable the discipline and the competition are given the same name. Ok, actually the competitions are Individual/Pair/Group Freestyle, but the first part often is omitted when speaking with others, which leads to even more confusion. Time to clear it up.

Freestyle Discipline

Freestyle, amongst all other artistic unicycling disciplines and also gymnastics, dancing, figure skating, etc. are typed as a technical compositorical sport (or composite in english?). Technical (unicycling and non-unicycling), because that’s the most present athletic component, which freestylers rely on and compositorical because all the tiny and atomar technical bits are composed together.

Dictionary.com has a good definition for freestyle: “a performance or routine featuring relatively free, unrestricted movement or intended to demonstrate an individual’s special skills or style, as in figure skating, gymnastics, or surfing.” which applies to Unicycle Freestyle, too. Wikipedia has a list with other sports that have freestyle in their name, which also fall under this definition. I think it’s enough to state the relationship between freestyle and related other sports.

Freestyle Competitions

The german wikipedia gives a little but precise definition for what freestyle is: “Freestyle is a term for free improvisation”. So how do free improvisation (freestyle) and routine go together? Well, they don’t do and they are the opposite to each other. Luckily, there is another definition for both freestyle and routine which is widely adopted in dancing, figure-skating, rythmic sports gymnastics (RSG), etc.. The definition is about the musical representation and applies to Unicycle Freestyle, too:
Routine: “Choreographed movements”
Freestyle: “Improvised movements matching the music” (Pavicic, 2007, p. 87f)
The term freestyle is coined during the breakdance revolution in the early 80′s, when b-boys and b-girls were improvising their moves to music (which was revolutionary that time).

The Components of Freestyle

Almost every compositorical sport consists of 3 major components. In their generalized name, these are: object technic, body technic and choreography. Every sport has its own names for them, so do we (well, kinda). The object of course it the unicycle and we unicyclists show certain technics, which we call tricks. In sports, such as RSG these objects are for example a band, a ball, clubs, in gymnastics these are the gymnastic elements, etc.. For body technic and choreography, this isn’t seen as two separate things in unicycling (for what reason ever) and called presentation. Let’s dive in all three components individually.

1. Tricks

Tricks are the technics in artistic unicycling. There are many structs in which they can be grouped, they show a hierarchy and share a lot of similarities which relates them to each other (Gossmann, 2011). Today, it’s guessed around 1000 different tricks exist in unicycling.

2. Artistics

Artistics (or body technic) refer to everything you are able to do with your body. Movements and their technics from three big fields get soaked in here: dancing, acrobatics and acting.

  • For dancing there are known plenty technics which can be used, from an isolation-driven jazz dance and its technics (e.g. popping and locking) to modern dance style with its technics (e.g. contract & release and fall & recovery).
  • Acting then is more facing the mimics and gestics during your play. Feelings can be expressed in both forms (dancing and acting), however I would consider dancing the more abstract one.
  • Acrobatics is a great field and is the home of highly coordinational and conditional movements. From a general perspective, unicycling tricks would run under the term acrobatics but since we are in the unicycling land, this is our special field and thus got separated. Anyway, everything non-unicycling acrobatics is meant here.

I would like to use this opportunity to talk about ballet. It is in the rulebook, since I can remember reading it (along with jazz dance and modern dance) and I hardly believe anybody knows why and only combines stereotypes from ballet with Unicycle Freestyle. Ballet is the base for almost every sport (yes, NHL teams have 2x ballet training per week) and especially for dance-oriented this is were elegancy is trained (even Arnold Schwarzenegger did ballet to improve his performance elegancy as a body builder). Despite from sports actors often have some additional education in dancing/ballet to support their acting.

From now on, I will use the word artistics, as described here.

3. Choreography

Wikipedia delivers a very good definition: “Choreography is the art of designing sequences of movements in which motion, form, or both are specified. Choreography may also refer to the design itself. The word choreography literally means “dance-writing” from the Greek words “χορεία” (circular dance, see choreia) and “γραφή” (writing). A choreographer is one who creates choreographies by practicing the art of choreography”.
Under choreography the two components from above are unified together. Tricks and artistics play well into each other hands interpreted to music. Along with the mentioned music, there are more constraints in unicycling for a choreography, which can be the theme and the costume to form one unit.

Choreography though must be treated in a special fashion. Whereas tricks and artistics are two components that entirely relate to skills of a rider, this does not apply to choreography. Your coach may create the choreography, which the rider is passing through 1:1 to the audience. Your mum may tailor your costume, your dad may craft the props decorations and a good friend of you, who is a soundartists, may cut the music for you. At the end in your routine you present something which is a team product. Thus, the former two components (tricks and artistics) relate to the athletism (rider skills) where choroegraphy is more like organizing things (3rd person skills).

A Component Infographics

I made a graphics to illustrate where everything is belonging to. This figure does not aim to be complete:

freestyle-components

The Components Pyramid

All these components, stack up to a pyramid (see graphic below). The lowest layer is the tricks, followed by the artistics as the middle layer and the final top layer is the choreography. The layers are dependend on each other. The first one, is of course the tricks, without them we wouldn’t be in the land of unicycling, so they are the fundament for the pyramid. The second one, the artistics bring of course the artistic expression into unicycling, they build upon the tricks (without it would be called dancing). The choreography as mentioned above forms both into one unit.

Freestyle Competition Landscape

Now, that the components for Freestyle are identified, we can build competitions from it. Depending on how much layers from the pyramid are used, many different competitions can come out from one layer. They are build out of the same components, but the mode of the competitions makes the difference. I made a little infographics to illustrate this.

freestyle-competition-landscape

So, I listed some possible competitions. I would like to hear yours and I would like to go into the details for each of mine.

UniDancing

UniDancing combines all three components. In the best there is an equal weight in the usage of tricks and artistics. Which might be some extraneous dance moves, some cool acrobatics, very nice acting or another way of showing impressive artistics. The choreography combines all that on top of tricks.
UniDancing can be done individually, in pairs or groups.

Freestyle

This is where the definition from freestyle comes back in, a “free improvisation”. Setup can be similar to UniDancing, give the rider its natural environment, give him a music and he must interpret the music with tricks and artistics to, of course the rider doesn’t know the music before his start.

Freestyle Battles

This is an addition to Freestyle above, mainly influenced by breakdancing. Riders can start individually or in teams. Battleing against each other by interpreting music with tricks and artistic and having a fiercy non-verbal communication between the two rivaling parties through body language.

Open-X / “xtreme” Freestyle

This is just about tricks. Nothing else. Some music but neither representation nor interpretation is beeing judged, just supplementary for the competition. Two minutes just kickin’ tricks.

Flatland

Flatland, for the sake of completeness, is the about bare tricks, too. The winner is crowned after an eliminating tournament through battles with a possible preliminary round.

Today’s Freestyle – Some criticism

Today’s Freestyle isn’t build with that deep understanding of the sport and neither of its components. Thus a lot of things got mixed up, which resulted in using existing terminology wrongly. Another thing is talking about a term (e.g. Freestyle) out of two different point of views, that should be handled separately. The required differentiation is lost and the phenomenons are still present today. I’d like to state some of these false statements:

  • The proper name for the Freestyle Competition IS UniDancing.
  • Basically everything in presentation judging is mixed together in many, many wrong ways.
    • The definition for choreography in the rulebook looks like it’s taken from wikipedia and then changed to something wrong (plagiarism + betrayal).
    • The proper word for synchronization is musical interpretation and synchronization a analog or congruent interpretation are just two of the four possible forms that exist (Others are contrasting and autonom) and they even may be mixed in one single routine (Dieter-Rotenberger, 2008, p. 7).
    • Choreography vs. Artistics
      • Artistics is judged in many different categories. In 3.23.2 Choreography and Style, 3.23.3 Showmanship and Originality and 3.23.4 Interpretation: Costumes, Music and Props, where actually style gets repeated unnecessarily and judged twice (unnecessary redundance).
      • Choreography is judged in many different categories. Almost everything in 3.23.4 Interpretation: Costumes, Music and Props, 3.23.2 Choreography and Style and in 2.23.3 Showmanship and Originality.
      • Originality and Total Impression in 3.23.3 are hybrids, they favor either artistics and/or choregraphy depending on the routine.
      • Choreography vs. Artistics in numbers:
        Section Choreography Artistics
        3.23.2 7.5 (Composition + Choreography) 2.5 (Style)
        3.23.3 3.75 (half Originality + half Total Impression) 11.25 (half Originality + half Total Impression + Expresiveness + Showmanship)
        3.23.4 7.5 (Costume, Music, Props) 2.5 (Style)
        Sum 18.75 16.25
        Presentation % 37.5% 32.5%
        Total % 18.75% 16.25%

        Interpretation of the values above:

        • The table shows the score that is targetting choreography resp. artistics.
        • Hybrids are counted halfways on each side.
        • The percentage values mean, how much is the presentation/total score affected by that specific component.
        • I’m yet unsure about the musical interpretation.
    • Artistics should have the same weight as tricks, they haven’t 50% vs. 16.25%.
    • Rider skills are judged lower than 3rd person skills (choreography vs. artistics)? Oh god.
    • Why the hell are dismounts (a totally technical aspect) scored in presentation? No rider ever gets this.
  • The interpretation sections for each side (technical and presentation) can only be seen as a rescue scream, because of an insufficient understanding of freestyle. The creators of the judging system might have thought they give an additional to judges to fill in some judgements they couldn’t fill in elsewhere, because they didn’t understand the sport very well enough. We ran a survey in germany about Freestyle judging. At the end there was a free field for participants to enter their meaning. Guess what? Most people complained they have no idea what to do with the interpretation category.
  • The 50% of the technical aspect are therefore section 3.22.1 – 3 and 3.23.1.

This is just a rough overview of what has gone wrong over the past years, unfortunately this has a very crucial impact on the riders.

1) We wrongly educate riders. Once they read in the rulebook, find a definition for something they most likely believe in what they read. We must stop teaching this mistakes and better educate riders, coaches and judges. As a better understanding will also better lead them to what they need to focus when practicing.

2) The judging scores are a feedback to the riders (or at least should be). Once they see their scores and see, ok I my total score got 70% from technical and 30% from presentation, they may come to the conclusion they should practice more presentation. Digging in a level deeper, you can observe if your technical deficiencies are stemmed from their quality, their difficulty or something else. Same should be possible for presentation. What’s the feedback for the rider at the moment? A skirmish of randomly arranged numbers with no relation to the distinct aspects the rider has worked for so hard.

Further Freestyle Development

For the development of Freestyle, there is very, very… very much to clean up. I propose the following:

Short-term goals: Provide slots to plug in new Freestyle competitions and EDUCATE people. The IUF plans to start its education plattform in summer 2013 and two courses by me (that I hold at Unicon 16) are waiting to see the light of the world.

Mid-term goals: Reform the Freestyle competition landscape. Create more knowledge about unicylce freestyle*.

Long-term goals: Create reliable rules for each competition, that live longer than two years (The work on the new Freestyle UniDancing rules will start in fall 2013, I will lead this committee).

* If you thought, now that I layed off all that insights, you are wrong. This is just the start, this is only an introduction, the preamble. This is really hard work and I happily repeat myself in describing it with the following words: We want unicyclists to give more than their best at competitions they can expect the same from us.

 

Thanks for reading.

Installing OpenLDAP on Debian Squeeze with OLC

On 27. Januar 2013, in Web, by Thomas Gossmann

There are a lot of tutorials out there, that tell you how to install ldap and set up its configuration. Since version 2.3 OpenLDAP has changed to a dynamic runtime configuration, also called OLC (OpenLDAP Configuration or On-Line Configuration) but tutorials barely exist. This tutorial should help you set up your OpenLDAP with this dynamic configuration, secure your LDAP server with SSL, install some goody modules, create the first LDAP database and help you with a wonderful tool to either help managing your LDAP server but also your databases. LDAP made easy… kinda.

Installation

Ok, easy start with the installation. Run the following command:

> apt-get install slapd ldap-utils

This will install openldap and the ldap utilities on your server.

Accessing cn=config

Installation is done, time for the configuration part. The LDAP server stores its configuration in a DIT style database, with its root cn=config. To access the DIT, you need to bind to the configuration. In order to do that it is necessary to create a root DN and password. First check if there already is a olcRootDN. Running the following command:

> ldapsearch -Y EXTERNAL -H ldapi:/// -b cn=config

This will output a lot to your terminal. At the end there is the database configuration. Look for the # {0}config, config database and check if there is olcRootDN present. If so, you may use that one, or change it. First create a password for the root:

> slappasswd

Enter your password twice and you get the password hash. Next is creating a ldif file to create the olcRootDN and its password in the configuration database, I named it config.ldif:

# uncomment this part, if there is no olcRootDN present
# use replace instead of add, if you want to change the root dn
#dn: olcDatabase={0}config,cn=config
#changetype: modify
#add: olcRootDN
#olcRootDN: cn=admin,cn=config

dn: olcDatabase={0}config,cn=config
changetype: modify
add: olcRootPW
olcRootPW: secret

Remember to replace secret with your created password above. Add them to your LDAP server with the following command:

> ldapadd -Y EXTERNAL -H ldapi:/// -f config.ldif

And test your binding with your root DN:

> ldapsearch -b cn=config -D cn=admin,cn=config -W

this will ask for your freshly created password. Enter it and you will see the same result as above. That’s it, now the LDAP server and configuration is accessible. Time to fill it with some content.

Managing the LDAP configuration

Managing the LDAP configuration via command line is a pain. Luckily there is a wonderful tool available, that helps you with that and even gives you auto-completion for all the available schemas. It’s called Apache Directory Studio and runs on Mac, Linux and Windows. I will use APD now, to continue with the configuration as it is much more comfortable (Screens show the german version).

Apache Directory Studio

(1) Click to create a new connection, which brings up the new connection wizard (2). Give it a descriptional name, enter the hostname. For now, leave port 389, and normal ldap encrytpion we will secure it in a second. Hit the check connection button. A popup will hopefully tell you, the connection works. Click next.

ldap-credentials

Enter the Bind DN which is cn=admin,cn=config, the bind password from above and click check authentication. The friendly popup will tell you, it works. Click next.

ldap-basedn

Uncheck the upper left checkbox and enter the Base DN (since we know it, we don’t need APD to find it for us). Enter cn=config as Base DN. Click finish; a connection will automatically established and  will be opened in the LDAP browser.

Securing OpenLDAP with SSL

To secure the LDAP connection over SSL, add the CAcertificate, the servercert and the serverkey to the configuration. In the freshly opened connection, click the cn=config tree node in the the LDAP Browser. You can see the existing attributes on the selected entry in the middle view of APD. (1) In the toolbar of that view you can add new attributes and the best is auto-completion. The attributes to add for SSL are: olcTLSCertificateFile, olcTLSCertificateKeyFile, olcTLSCACertificateFile.

ldap-newattrib

After adding these attributes, there’s one more to add to /etc/default/slapd. Change the SLAPD_SERVICES and change to the ldaps:/// protocol. Mine looks like:

SLAPD_SERVICES="ldaps:/// ldapi:///"

Now restart slapd:

> /etc/init.d/slapd restart

To test this, you can run nmap port scan or try to reconnect to your server in APD, which should refuse to connect. Now, edit your connection in APD, change the port to 636 and select ldaps:// as encryption.

P.S. In case you don’t want to expose your LDAP server that short time without beeing secured via SSL, you can of course write an ldif file with the three attributes and add them the same way as config.ldif.

Creating a LDAP Database

Finally, create a LDAP database.

  1. Create a new entry by right-clicking on cn=config in APD, select new > new entry… and click next. Time to consider which database backend should be used. OpenLDAP ships with HDB, that’s going to be used. That means the objectClass to use is olcHdbConfig.
  2. Next is the RDN which is olcDatabase as key and the value must be the type of the database, hdb.
  3. Clicking next and give the required attribute olcDbDirectory a value. olcDbDirectory maps to a physical path on your server, where the contents for the LDAP database are stored. The folder must have openldap as user and group ownership.
  4. There is another mandatory parameter which is olcSuffix. Add this, to give your database a DIB (Directory Information Base, like dc=example,dc=com). It isn’t shown as a must parameter, Howard Chu explains: “This is just an artifact of slapd.conf support. Since slapd.conf files aren’t affected by the olc objectclass definitions, we need to put the enforcement in the common code instead of in the schema.”.

See Also: Add/Delete Databases on LDAP for Rocket Scientists

Database is created, now it’s time to add olcRootDN and olcRootPW, olcAccess rules for your database and olcDbIndex to improve performance. Here is an idea for an index:

index   objectClass             eq
index   cn                      pres,sub,eq
index   sn                      pres,sub,eq
index   uid                     pres,sub,eq
index   displayName             pres,sub,eq
index   default                 sub
index   uidNumber               eq
index   gidNumber               eq
index   mail,givenName          eq,subinitial
index   dc                      eq

From: LDAP/OpenLDAP Setup (Debian Wiki)

Enable memberOf

Installation

When working with groups and you want to filter for users with a specific membership. This is done with the ‘virtual’ attribute memberOf. This functionality is not enabled by default and must be installed as a module. The installation is been done with one attribute. Browse to cn=module,cn=config in APD and add a new attribute olcModuleLoad. Give it the memberof value. It will change to {n}memberof where n is a numeric value. That’s fine, that’s how OpenLDAP manages multiple values. There will be {0}back_hdb and memberof will become {1}memberof, so two modules will be installed by then.

See Also: Add/Delete Modules on LDAP for Rocket Scientists

Usage

In order to enable the virtual attribute memberOf for a database create an overlay. Right click the database in the APD LDAP Browser > new > new entry… and click next. The objectClass is olcMemberOf (you may need to click the refresh button next to the search field). The RDN is olcOverlay and the value is memberof. Add the following values:

ldap-memberof

You should adjust the attributes olcMemberOfGroupOC, olcMemberOfMemberAD and olcMemberOfMemberOfAD to match your setup.

Da Einradfahren noch eine sehr junge Sportart ist, ist die Entwicklung dieser Sportart in vollem Gange. Gerade diesem Prozess, so scheint es zumindest schenken die Einradfahrer am wenigsten Beachtung. Oft hört man das Argument "Da kann man doch eh nichts ändern" Stimmt nicht! Genau das Gegenteil ist der Fall.

Wie der Hase läuft, wie die Entwicklungsarbeit geleistet werden kann und  wird und wie ihr als Fahrer dazu beitragen könnt? Lest einfach weiter.

Die IUF

Was'n das jetzt? Diese IUF, ich glaube ich habe schon mal davon gehört. IUF, das steht für International Unicycling Federation  und ist der Einradweltverband. Er kümmert sich unter anderen um das Regelwerk das bei Wettkämpfen zum Einsatz kommt. Dieses Regelwerk (engl. Rulebook) wird nach jeder Unicon von einem Rulebook Committee, also einer Arbeitsgruppe überarbeitet. Um diese Arbeitsgruppe zusammenzustellen wurden Emails an alle Mitglieder verschickt und es gab Veröffentlichungen auf der IUF Homepage, im Unicyclist Forum und auf Facebook. Wer daran mitarbeiten möchte konnte sich dazu bereit erklären. Einen bestimmten Erfahrungsschatz oder Qualifizierungen sollte man dazu mitbringen. Diese Personen kommen aus vielen verschiedenen Ländern und arbeiten nun an Regeländerungen für jede Disziplin. 101 Einradfahrer haben sich dazu gemeldet und arbeiten bis ende januar in 9 Bereichen. Ihr könnt ihnen auch bei der Arbeit zusehen.

Die deutschen Vertreter

Auch aus Deutschland sind viele Personen im Rulebook Committee vertreten. Aber was machen die eigentlich? Woran arbeiten die? Wir haben dazu immer Mittwochs in Skype eine Gruppe gestartet an der immer mehr teilnehmen um die gegenwärtigen Regeln zu diskutieren und Verbesserungen dafür zu finden. Und diesen Prozess legen wir natürlich offen, damit jeder sehen kann, was wir tun und woran wir gerade arbeiten. Dazu haben wir zwei Dokumente:

1. Brainstorm, Ideen und Proposals

Hier sammeln wir Ideen für Regeländerungen, besprechen diese im Detail oder arbeiten auch konkrete Änderungen aus.

2. Protokolle

Um nachzuverfolgen, wer wann wobei mitgewirkt hat haben wir ab dem 21. November begonnen Protokolle mitzuschreiben. Die Protokolle bieten eine Zusammenfassung was während des Meetings besprochen wurde.

Und ich? Wo kann ich mitmachen?

Wir sind uns sicher, von euch kommen großartige Ideen, Wünsche, Vorschläge!  Kritik ist auch gerne gesehen, sagt am besten aber auch immer das Warum dazu und auch wenn ihr zornig und wütend seid weil euch irgendetwas stinkt und ihr das ändern wollt. Ihr alle habt nun drei Möglichkeiten:

1. Schreibt eine Email.

So einfach es klingt, tut es. Eine Liste mit Email-Adressen gibt es im Brainstorm, Ideen und Proposals ganz unten. Schreibt demjenigen, den ihr kennt. Ihr könnt auch eure Trainer fragen, an wen ihr euch wenden könnt.

2. Diskutiert mit

Die IUF hat ein Diskussionsforum eröffnet indem jeder mitdiskutieren kann. Jeder, der an der Unicon war, hat sogar bereits einen Account und kann sich direkt einloggen. Alle anderen können sich kostenlos einen erstellen. Einloggen und Account erstellen wird in einem kleinen Hilfetext erklärt.

3. Es gibt eine Facebook-Gruppe dazu.

Felix und ich haben dazu die Einrad-Deutschland Facebook-Gruppe gegründet. Jeder kann der Gruppe beitreten und seine Wünsche oder Kummer von der Seele schreiben.

Warum eine Facebook-Gruppe?

Nicht alle haben Facebook und schon gar nicht die Leute, die im Verband sitzen?!? Felix und ich haben alles probiert um die Facebook-Gruppe mit einer Mailinglist zu verbinden. Eine Mailingliste ist eine bestimmte Email-Adresse an die jeder eine Email schicken kann und alle die in dieser Liste eingetragen sind erhalten die Email. So kann man verschiedene Themen diskutieren. Dieses Unterfangen ist jedoch gescheitert. Also hatten wir die Wahl, ob wir eine Mailingliste nutzen, auf der jeder schreiben und lesen kann oder wir gehen dorthin, wo eh schon sehr viele Fahrer sind. Wir haben uns für letzteres entschieden da dort viele aktive Fahrer sind, bieten allerdings die Möglichkeit an, die Themen die in der Facebook Gruppe besprochen werden auf einer Seite zu lesen. Die Idee dazu kam ursprünglich von Maren Schindeler-Grove aber auch Petra Plininger, mit der wir die Idee besprochen haben, befand sie für sehr gut.

Unicycle Trixionary

On 8. Oktober 2012, in Training, Unicycling, UniScience, by Thomas Gossmann

The Trixionary is a unicycle tool for practice and also for unicycle science research. So I would like to talk a little why and how the Trixionary got created, how you can use it for practice and the future plans for it.

History

The Trixionary was created in june 2006. It’s original purpose was to collect unicycle tricks, structure them with decendants (tricks you should learn before) and ascendents (tricks you can learn after) and to have explanations from coaches for each trick. Once you are about to learn a trick you can open it in the Trixionary see the decendants that you might check for yourself (maybe learn  them first) and then pick one of the explanations that works for you. It gets an update just two month later to add some media support (mostly pictures) and a rudimentary video support for tricks. There was a bigger update happening in may 2010 to add the graphs (see the connections between a tricks and its descendants and ascendents), added structs as a way to organize tricks, new connections to transitions and variations of a trick and an experimental calculation for the difficutly of a trick.

Practicing with the Trixionary

As an individual you can open a specific trick on the Trixionary. On this page you can inspect which descendents are listed and which you might consider learning first. Then, as explained above you may pick on of the explanations which appear below a trick and see if they help you for your next round of practice. If so, you can click “Thank you” to vote this explanation up. Each explanation contains about multiple parts. One for beginners, one for experts (like a short explanation) and a detailed explanation. Then there are two fields for coaches, one how to instruct this to a student and a second one with additional tipps. You are also able to select which of these fields you want to see.

The interessting part so far are the connections between tricks. Head over to the graph showing all the connections between the tricks. If you go fullscreen (Vollbild button on the navigation panel on the right) you can see the huge canvas with all the connections. The Trixionary is the first tool, to make those connections visible.

So why are these connections so interessting? For example a Biellmann is connected to Standwalk (via Standgliding and Arabesque). So, the Biellmann is implecitely affected by the way you learn Standwalk and the quality of your Standwalk (for sure this counts for Standgliding and the Arabesque as well). Which means, if you have a mistake in your Standwalk the Biellman won’t work at all. The biggest mistake for Stand up tricks, of course, is using your hand to hold the seat and maintain balance. You actively avoid practice maintaining balance with your feet. Holding your hands on the seat for Standwalk and for Standgliding works (transition-wise) and for the Arabesque, this does not work for the Biellmann anymore, because both of your hands hold your free foot.
There are plenty of these connections, that are made visible by the graph, that coaches need to respect when instructing their students. If not, students pay the highest price possible: relearn a trick.

Future of the Trixionary

There is so much more for the Trixionary to come. These are the ideas:

  • Multilingual support and move it to the IUF website
  • Add trick properties
  • Better media support
  • Rethink the connections, there are some issues which descendents in which combination
  • Better organization of the full graph, with the possibility to highlight specific parts
  • Detailed movement descriptions (Kassats Action-Effect relations and Göhners functions-principle)
  • Exercises
  • Movement mistakes (with symptom, cause and recommended exercise)
  • Rethink the explanations that are currently entered in short, pro, detailed, trainer and trainer tipps
  • Experimental difficulty calculations
  • Public API, so the content is accessible outside the Trixionary

Hope you like this extensions as I do.

Now, go to the Trixionary and have fun in your next practice sessions with it.
