Enki is a sim­ple blog­ging app that I use for my own blog. It's cre­ated by Xavier Shay and is based on the assump­tion that if you're a coder then it's eas­ier for you to hack code than edit pref­er­ences.

Cuty­Capt is a com­mand line tool that uses WebKit that comes with Qt to ren­der and cap­ture web pages. In addi­tion to many image for­mats you can also save a web page to PDF which allows copy­ing and past­ing of text. WebKit is a great stan­dards-com­pli­ant browser engine (along oth­ers used in Chrome and Safari) and Cuty­Capt's com­mand line inter­face is par­tic­u­lary handy if you want to cap­ture web­page con­tents in a shell script. Cuty­Capt was writ­ten and is main­tained by Björn Höhrmann.

Inher­ited resources is a gem that helps Ruby on Rails appli­ca­tions to fol­low Skinny con­troller - fat model par­a­digm. It speeds up devel­op­ment and allows devel­oper to focus on what makes his con­trollers dif­fer­ent. The gem is main­tained by Jose Valim.

Awe­some Nested Set is an imple­men­ta­tion of the nested set pat­tern for ActiveRe­cord mod­els. Ini­tially cre­ated by Col­lec­tive Idea, now main­tained by dif­fer­ent peo­ple in sev­eral forks. I'm fol­low­ing the fork cre­ated at Rails­Dog and it's where I've sent my patch.
