Указания за проектите към курса "Програмиране с Руби"

В този документ ще събираме някои указания, които да ви насочат в избора на тема и в писането на вашите проекти към курса "Програмиране с Ruby".

Игри и друг GUI intensive софтуер

Когато сте избрали да пишете неща, наподобяващи игри — или каквито и да е други проекти, изискващи сериозно GUI — постарайте се да "откачите" основния си код максимално много от рисуването/графиката/GUI-то. Целта ви е да имате много ясно разделение и абстракция между "ядрото" на вашия проект и графичния му интерфейс. Добре би било основната логика на проекта ви да се намира изцяло в "ядрото", под формата на класове, модули и прочее, като това ядро предоставя на своите позлватели някакво API. Тоест, стремите се да пишете въпросното ядро все едно пишете библиотека, която ще се преизползва в друг(и) софтуер(и). От там нататък, GUI-то се прави като wrapper на тази библиотека, ползва публичното й API и е един вид pluggable компонент към нея.

Можете да минете и само с кода от основното ядро, който имплементира

On 37signals' "No Free Accounts" Policy

I've always liked 37signals as a company a lot and today they just shattered my affection for them into pieces.

Teaching programming voluntarily

We're a small group of volunteers teaching programming at a university in Bulgaria. Today we asked 37signals if they would provide us with a free Basecamp account. The account would help us coordinate our team teaching efforts and let us provide the students with more knowledge more efficiently.

As we're not getting paid anything for this by the university (although students get credits for our courses) and as we don't have any budget for course expenses (on the contrary—we pay from our own pockets in order to bring Ruby, Python and Clojure to the curriculum), we asked for a non-trial basic account pro bono.

No free accounts, no matter what
