Zadání
Do existujiciho projektu Sphene Community Tools, coz je komunitni portal s wiki, forem a blogem, postaveny na frameworku Django, pridam pocitani karmy. Tj, moznost hodnotit jednotlive prispevky ve foru a uzivatelum pocitat jejich „kvalitu“.
Kazdy prispevek ve foru dostane 2 tlacitka pro libi/nelibi. Bude se pocitat hodnoceni jednotlivych prispevku a rovnez hodnoceni uzivatelu. Hodnoceni uzivatelu bude zhodnocovat:
- Dobu po kterou jsou zaregistrovani/neaktivni
- Pocet prispevku
- Hodnoceni vlastnich prispevku
Hodnoceni nesmi prilis favorizovat nektere skupiny uzivatelu (jiz dlouho registrovane…)
Výsledné řešení
Výsledné řešení splňuje požadavky, tj: máme karmu, hodnoceni libi/nelibi, a hodnocení zahrnující výše zmíněná kriteria. Karma se dává v rozsahu (-4,4) a k tomu jsou mapovány úrovně červ, krysa, kráva, člověk, moudrý člověk a bůh.
Rovnice pro výpočet je následující
(arctan vypadá asi takhle :-),
čímž je docíleno, že k nejhorším/nejlepším karmám se člověk blíží mnohem pomaleji, než kolem karmy neutrální.
Výsledek pak vypadá asi takto
Zhodnocení
Komunikace s hlavním (a téměř jediným) vývojářem SCT byla velice vstřícná a bylo znát jeho nadšení o můj zájem. Avšak vzhledem k tomu, že nemá žádné jasně dané a formalizované procesy, tak nemůžu tušit, kdy se můj diff objeví ve vývojové větvi a zda-li krom prostého „díky“ se jím bude vlastně zabývat.
