Utah Teapot

All hail the Utah Teapot!

personal projects, of course, but let's count the only one that could actually be considered finished and released.

which was a local social network site. i was making and running it for about three years as a replacement for a site that its original admin took down without warning because he got fed up with the community. i loved the community and missed it, so that was my motivation to learn web stack (html, css, php, mysql, js).

first version was done and up in a week, single flat php file, no oop, just ifs. was about 5k lines long and was missing 90% of features, but i got it out and by word of mouth/mail is started gathering the community back.

right as i put it up, i learned about include directive, so i started re-coding it from scratch, and "this time properly", separated into one file per page.

that took about a month, got to about 10k lines of code, with about 30% of planned functionality.

i put it up, and then i learned that php can do objects, so i started another rewrite from scratch. two or three months later, about 15k lines of code, and 60% of the intended functionality.

i put it up, and learned about ajax (which was a pretty new thing since this was 2006), so i started another rewrite, this time not completely from scratch i think.

three months later, final length about 30k lines of code, and 120% of originally intended functionality (since i got some new features ideas along the way).

put it up, was very happy with it, and since i gathered quite a lot of user-generated data already through all of that time, i started seeing patterns, and started to think about some crazy stuff like auto-tagging posts based on their content (tags like positive, negative, angry, sad, family issues, health issues, etc), rewarding users based on auto-detection whether their comments stirred more (and good) discussion, or stifled it, tracking user's mental health and life situation (scale of great to horrible, something like that) based on the analysis of the texts of their posts...

... never got around to that though, missed two months hosting payments and in that time the admin of the original site put it back up, so i just told people to move back there.

awesome experience, though. worth every second.

to this day probably the project i'm most proud of (which is sad, i suppose) - the final version had its own builtin forum section with proper topics, reply threads, wysiwyg post editor, personal diaries where people could set per-post visibility (everyone, only logged in users, only my friends), mental health questionnaires that tracked user's results in time and showed them in a cool flash charts, questionnaire editor where users could make their own tests/quizzes, article section, like/dislike voting on everything, page-global ajax chat of all users that would stay open in bottom right corner, hangouts-style, private messages, even a "pointer" system where sending special commands to the chat aimed at a specific user would cause page elements to highlight on their client, meaning if someone asked "how do i do this thing on the page?", i could send that command and the button to the subpage would get highlighted, after they clicked it and the subpage loaded, the next step in the process would get highlighted, with a custom explanation text, etc...

dammit, now i got seriously nostalgic. it was an awesome piece of work, if i may say so. and i wasn't the only one thinking that, since showing the page off landed me my first two or three programming jobs, right out of highschool. 10 minutes of smalltalk, then they asked about my knowledge, i whipped up that site and gave a short walkthrough talking a bit about how the most interesting pieces were implemented, done, hired XD

those were good times, when I still felt like the programmer whiz kid =D

as i said, worth every second, every drop of sweat, every torn hair, several times over, even though "actual net financial profit" was around minus two hundred euro paid for those two or three years of hosting.
