Geocaching is an open air activity joining technology with physical exercise. In general it's a modern version of a treasure hunt using a GPS instead of the map. This year we offer two "caches", one for beginners and one advanced. The two cache visites are guided but experienced geocachers can do them on their own. The caches of Strossen Wibbelt are not official.<br />

Le Geocaching est une activité plein-air qui réunit technologie et exercise physique. En principe c'est une chasse au trésor moderne utilisant un GPS au lieu d'une carte. Cette année on propose deux "caches", un pour débutants et un pour avancés.<br />
Les deux caches sont accompagnés, mais les pros du caching peuvent les faire aux-mêmes. Les caches du Strossen Wibbelt ne sont pas des caches officiels. <br />

<br />
==Todo==<br />
* we have only one GPS, would need some more [todo]<br />
* batteries for GPS [ok]<br />
* shall we put gimmicks in the cache? Yes. [ok]<br />
* buy cache container(s), last time we gave the container with the money away. Bad idea :-) [..]<br />
* create beginners and advanced cache boxes [..]<br />
* print the posters for the schedule & plastify [todo]<br />
* create banner "geocaching" [..]<br />
* create poster/flyer with QR codes for geocaching apps [todo]<br />
* do a pre run of the geocaches with all people which will be on the booth [ok]<br />
<br />
== Setup ==<br />
=== Material ===<br />
Put all this in the event box. Cover the box with plastic in case it's rainy<br />
* posters with the timing [todo]<br />
* duct tape [ok]<br />
* white board markers [ok]<br />
* syn2cat banner [ok]<br />
* hypnocube [ok]<br />
* 50m extension cord [ok]<br />
* GPS devices [..]<br />
* beginners cache box [todo]<br />
* advanced cache box [ok]<br />
* envelope [ok]<br />
* le huge geocaching banner [ok]<br />
<br />
=== what where ===<br />
Need several people<br />
* install advanced cache (needs 30 minutes setup!)<br />
* put posters up<br />
* hang syn2cat banner inside tent<br />
* connect hypnocube<br />
* program GPS with the initial coordinates of the 2 caches<br />
* install beginner's cache<br />
<br />
== Activity ==<br />
Depending of the available people on stand start a geocaching tour every 30 minutes. The beginners lasts 20 minutes, the advanced 45 minutes.<br />
* explain what geocaching is<br />
* go with a group to the cache, give GPS recievers to group. Do not lead them.<br />
* advanced: on each waypoint give 5-10 minutes to solve. Explain that sometimes on other caches this can be much more complex.<br />
* at the cache people can put donation in box. For security, go back and recover the money from box.<br />
<br />
== Teardown ==<br />
Don't run all away<br />
* recover the 2 cache boxes<br />
* give money to the organizer in envelope<br />
* put everything back in event box. If it rains: cover with plastic! <br />
* recover advanced cache material<br />
<br />
Back at the space:<br />
* put all geocaching relevant material into the geocaching box into syn2stock<br />
* stow away the banner<br />
* reconnect hypnocube in chillychill<br />
* put back duct tape, markers, power cable</div>Lala//wiki.syn2cat.lu/wiki/User:LalaUser:Lala2012-04-11T17:51:15Z<p>Lala: </p>

The goal of this contest is not to find the best coder, but to enjoy coding together and to motivate others to start coding. If you can write a "hello world" program in any language, you are welcome. There will be certainly someone to help you to solve the tasks.<br />
<br />
We will use the following example problem to make us familiar with the contest system.<br />
<br />
<br />
== Sample problem ==<br />
<br />
Mr. Foo has to determine if his students have passed the year. As he has many students which have written many tests, he can't use his calculator, because it would take him too long. He knows that you are a skilled hacker, so he has asked you to make a program to automate his task.<br />
<br />
He has '''S''' students. Each student has written '''N''' tests. The test scores ranges from 0 to 60 (both inclusive). A student has passed his year if he has an average score of more or equal to 30. The average is not rounded.<br />
<br />
<br />
=== Input ===<br />
<br />
You are given an input file. The first line consists of 2 integers: the number of students S (1 <= S <= 1000) and the number of tests N (1 <= N <= 1000). S lines follow, which consists of N integers, representing the scores of a student.<br />
<br />
<br />
=== Output ===<br />
<br />
You have to create an output file which contains one line per student. Each containing 'PASSED' if he has passed his year, otherwise 'FAILED'.<br />
<br />
<br />
=== Input example ===<br />
<br />
4 2<br/><br />
29 30<br/><br />
30 30<br/><br />
50 60<br/><br />
0 58<br />
<br />
=== Output example ===<br />
<br />
FAILED<br/><br />
PASSED<br/><br />
PASSED<br/><br />
FAILED<br />

= Copper =<br />
Half adder built out of copper. The marbles replace the fingers pushing the buttons of the Lego version. The marbles will propagate the bit flow to the next logic gates. In the middle you can see the XOR-AND mechanical combination as known from the Lego version which does the logic. The marbles flowing into the input are "lost", like in a real logic circuit. And new marbles are released at the bottom depending on the logic decision.<br />

The goal of this contest is not to find the best coder, but to enjoy coding together and to motivate others to start coding. If you can write a "hello world" program in any language, you are welcome. There will be certainly someone to help you to solve the tasks.<br />
<br />
We will use the following example problem to make us familiar with the contest system.<br />
<br />
<br />
Problem:<br />
<br />
Mr. Foo has to determine if his students have passed the year. As he has many students which have written many tests, he can't use his calculator, because it would take him too long. He knows that you are a skilled hacker, so he has asked you to make a program to automate his task.<br />
<br />
He has '''S''' students. Each student has written '''N''' tests. The test scores ranges from 0 to 60 (both inclusive). A student has passed his year if he has an average score of more or equal to 30. The average is not rounded.<br />
<br />
<br />
Input:<br />
<br />
You are given an input file. The first line consists of 2 integers: the number of students S (1 <= S <= 1000) and the number of tests N (1 <= N <= 1000). S lines follow, which consists of N integers, representing the scores of a student.<br />
<br />
<br />
Output:<br />
<br />
You have to create an output file which contains one line per student. Each containing 'PASSED' if he has passed his year, otherwise 'FAILED'.<br />
<br />
<br />

=Stroossen Wibbelt=<br />
==Meeting point==<br />
The place we meet is at 8h15/8h30 latest at our booth. For those who will be there, croissants await you! ;-)<br />
<br />
==='''IMPORTANT : Your car can be parked behind the commune (underground parking) up to 8h30 latest, but it can't be moved from there until 13h00! All other parking lots are closed due to the event!'''===<br />
<br />
==Introduction==<br />
In a few weeks' time, the community of Strassen will organise the "Stroossen Wibbelt" once again. As we promised our help last year, we want to offer the following activities :<br />
<br />
* geocaching with a special event cache<br />
* build your own throwie(s)<br />
<br />
In order to do that, the commune has given us a booth where we can set up our stuff and depart for the geocaching activity. As we need some help to do this, I would ask you to please lend us a hand and contribute your valued help. You won't have to be an expert of throwies or geocaching, all we need is presence in the booth and a hand here and there.<br />
<br />
The activities will '''start at 9h00''' and end '''at 13h00 latest''' Geocaching will be held every hour for a duration of more or less 45 minutes each. Throwie building will go through the whole day. All funds will go directly to the pott of "Stroossen Wibbelt". The collected funds during the day (of all activities) will be sent to the "Kriibskrank Kanner" foundation located in Strassen.<br />
<br />
So, please return your registration including your TShirt size and timeslot you want to spare by adding your name here below<br />
<br />
==Geocache "WibbelCat"==<br />
The idea was brought forward to design a "pot" which our participants should find geocache style. After having found the pot, everyone could donate a certain amount to it and it would be reburied for the next group.<br />
Anyone who has a kind of a plan, please enter your details here:<br />
<br />
===container===<br />
<br />
A classic container, inside a logbook and a donation box. That means that the container has to be big enough. So size = standard.<br />
<br />
We might need two containers, though as we will make two caches<br />
<br />
===type===<br />
<br />
There will be 2 sorts of caches :<br />
<br />
*Traditional (easy) one : single location, single box<br />
*Advanced one :Multicache featuring 3 WPs and a final box<br />
<br />
===location===<br />
<br />
Locations of caches have been defined. Contact us for more information (sorry, no spoilers here)<br />
<br />
Thanks<br />
