Rails Girls - ensikosketus ohjelmointiin
Teknologia tulee ilon tielle.
Tarvitaan siis periaatteita.
Alice nauroi. “Ei kannata yrittää, ei mahdottomia asioita voi uskoa.”
“Et ole tainnut paljoa harjoitella”, sanoi kuningatar.
“Sinun iässäsi minä harjoittelin sitä puoli tuntia joka päivä. Jaa jaa, joskus minun on onnistunut
uskoa jopa kuusi mahdotonta asiaa ennen aamiaista.”
- Alice Peilintakamaassa, WSOY 2010
Mahdollisuus numero 1: Minäpystyvyys
“Would you tell me, please, which way I ought to go from here?" "That depends a good deal on where you want to get to." "I don't much care where –" "Then it doesn't matter which way you go.”
― Lewis Carroll, Alice in Wonderland

Mahdollisuus numero 2: Suuri tipahdus
“It’s no use going back to yesterday, because I was a different person then.” ― Lewis Carroll, Alice in Wonderland
Jos JavaScript on uusi eka vieraskieli, tarvitsemme kielioppituntien sijaan runonlausuntaa
En ole lastenkirjailija, kuvittaja, enkä

Mahdollisuus numero 3: Uuden aloittamisen hinta
on nolla.
“Begin at the beginning," the King said, very gravely, "and go on till you come to the end: then stop.”
― Lewis Carroll, Alice in Wonderland
Nobody tells this to people who are beginners, I wish someone told me. All of us who do creative work, we get into it because we have good taste. But there is this gap. For the first couple years you make stuff, it’s just not that good. It’s trying to be good, it has potential, but it’s not.
But your taste, the thing that got you into the game, is still killer. And your taste is why your work disappoints you. A
lot of people never get past this phase, they quit. Most people I know who do interesting, creative work went
through years of this. We know our work doesn’t have this special thing that we want it to have. We all go through
this.
― Ira Glass
Uuden aloittamisen hinta on lähellä nollaa.

Riskin ottaminen vetää mukaansa ne ihmiset, jotka saavat aikaan asioita. Siksi riskejä on pakko
ottaa. Vain muutos on kiinnostavaa.
Riskistä.
Mahdollisuus numero 4: Koodi on käsityö, tai eka vieras
kieli
“Curiouser and curiouser!”― Lewis Carroll, Alice in Wonderland
1. Ongelman purkaminen osiin.
2. Kaavojen tunnistaminen
3. Algoritmien luominen
4. Ratkaisujen yleistäminen ja automatisointi.

Millaisia ohjeita? Täsmällisiä, oikeassa järjestyksessä, ilman
kirjoitusvirheitä. Tarpeen tullen muutettavissa

Tietokone, tee mulle leipä.
Valmiin toiminnallisuuden sisältävä kieli, esimerkiksi JavaScript tai Ruby
Tee voileipä.
Keskitason ohjeita vaativa kieli, esimerkiksi C
Kävele kaapille. Ota kaapista leipäpussi. Aseta leivät pussista pöydälle. Voitele leipä.
Hyvin yksityiskohtaiset ohjeet vaativa kieli, esimerkiksi konekieli Assembly
Ota askelia kohtisuoraan, kunnes saavut keittiön kaapille. Kun saavut kädenmitan päähän kaapista, pysähdy. Nosta vasen kätesi. Avaa kaapiston vasen ovi tasan 90 asteen kulmaan kaapin alareunaan nähden. Käyttäen oikeaa kättäsi tartu ylimmällä hyllyllä olevaan leipäpussiin. Siirrä pussi pöydälle. Jos pussissa on suljin, poista se. Tartu pussissa olevaan ensimmäiseen leipään. Ota leipä pussista ulos. Laske leipä pöydälle. ...
Kun tietokone lopulta osaa tehdä yhden leivän, se tekee sen täydellisesti. Joka kerta. Toisin kuin kuusivuotias tai edes aikuinen, yhden
voileivän tehtyään tietokone voi tehdä tuhansia ja taas tuhansia leipiä. Se ei koskaan kyllästy.
Tietokone on kärsivällinen ja tarkka, varma ja nopea. Siksi se on loistava työkumppani
tekemään asioita ihmisen ohjeiden perusteella.
Pienet tytöt ei tiedä, että
niiden ei kuulu TYKÄTÄ
tietokoneista.
Ei taikaa, eikä monimutkaista
.
Isotkin ongelmat ovat
nippu pieniä ongelmia.

Great dancing with you!
Conditions to start:When the music starts!Whe someone asks you to danceWhen you feel happy
Conditions to end:Repeat 5 times and stopDance until you’re out of breathDance while the music is on.
Can you think of things that are loops in your everyday life? Schooldays, routines, songs?
Hint:
Now it’s your turn!
My dance routine
Draw your own dance routine with the help of the blocks! You can add new blocks with new moves, if you like. Remember naming! Make the dance routine short, just a few blocks so that you can repeat it many times. Think also of what will stop the dance.

Entä mitä tietokoneen sisällä on?
Drawings that expressed connected parts, components, networks and elements by abstract drawings of wire connections and boxes linked with lines.
The Linkers
Represented computers as gears interlocking for a mechanical action to be carried out.
The Gear Gurus
Super technical drawings included resistors, wires, motherboards, and everything electronic to show that there exists nothing but elements which a current runs through. To our interpretation of their drawing, a computer is based on logic not magic, on connections not abstract things.

I am the processor. I am very smart and fast at calculating things. I am super busy bossing around and telling the other components what to do.
I am powerful in showing things on the computer screen, but I have a bad memory and I need the help of ROM and RAM.
I remember all immediate
things and run between the CPU and the Hard
Drive but I forget
everything once the
computer is shut down.
I am slow, but I keep good care of your pictures and games.
I remember all the important things and stuff that you don’t want to accidentally remove or have disappear when the power is turned off.

"Kuinka suuri nautinto tehdä jotain huolellisesti ja rakkaudella. Aloittaa
huolella ja ajatuksella, vajoutua ja jatkaa työtä lämmöllä jota ei mitkään
syrjävaikutukset tai hätäileminen ja artistimainen turhamaisuus keskeytä ja
muuta inhoksi.
Tehdä vähän, mutta hyvin. Tehdä niinkuin parhaiten tuntee, eikä ajatella
suurenmoisuutta. " - Eero Järnefeltin päiväkirjasta, 4/1897
Lopuksi
Teknologia on ihmisyydelle rakennettu.
Computer (km-pytr) n. person who makes calculations or computations; a calculator, a reckoner; spec. a person employed to make calculations in an observatory, in surveying.
Technology (from Greek τέχνη) Techne, "art, skill, cunning of hand"; and -λογία, -logia[1]. Techniques, skills and competencies alongside the tools needed to do the job. Agriculture is a technology; democracy is a technology.
Melkein kaikki tapahtuu vahingossa, yllättäen ja
odottamatta.
Siksi kannattaa antaa sattumalle mahdollisuus.
