for company developing automated photo-booth. goal capture photo , after quick review publish photo company's facebook page, automated. end registered app, , application conceptually done , works. developers of app can see photos, seems because app not "reviewed facebook" yet. when read required reviewed, facebook needs able test , verify app. impossible because app works in combination hardware on site, , not meant else use it. am solving right way? can approved users, "private" app? i'm not sure go here. if no user authorization involved , use extended page token page (that valid forever), don´t need go through review. set app public in "status & review" section of app settings. the app work without review role in app (admin, developer, tester).

i'm using nools rule engine , have necessity of modify rules on fly without impacting rule engine integrity. so far using default 'main' action group store default rules , using specific action group store rules belongs company. if company want change/add/delete rules need create again entire flow. wasn't able find in documentation. me remove flow ( contain rules companies ) , create again seems work rules crud operations. because of started think maybe flow per company better strategy still, if want change rules flow need removed , added again new rules, altered rules , without deleted rules. problem rules modified/deleted/add on fly. my questions: how other rules engines deal dynamical crud operations on rules? should using flow per company ? is there way add/delete/modify rules flow dynamically in nools? is there more rule engine style solution this? any appreciated. thanks i rather work on making object chaining (inheritance) based on ex

is there standard approach changing font size of whole html document? i'm thinking of 2 buttons, 1 increases font size , decreases font size. both of these buttons calls javascript function; function increasefontsize(){ //increase font size whole document } function decreasefontsize(){ //decrease font size whole document } question how do this? there more simple way 1 stated above? edit i'm using bootstrap , comes it's own css each html element. bootstrap defines default (body) font size 14px . one way if use em units on css , can use jquery solution can works. you can set global value on body change that: $(document).ready(function(){ var fontsize = parseint($('body').css('font-size'),10); $('.inc').on('click',function(){ fontsize+=0.5; $('body').css('font-size',fontsize+'px'); }) $('.dec').on('click',function(){ fontsiz

i wonder how establish transaction safety in restful apis, built around single entities. example database model: invoice item user-performed steps in browser: change order number. add item. remove item. edit item. requests made: patch / put invoice data/order number. post item. delete item. patch / put item. issue if after of requests above error happens, further calls might mess data integrity. additionally previous requests have made undone. e.g. if deleting item fails, steps 1 , 2 have rewound in order overall invoice how before. another problem might arise browser crash, dying internet connection, server failure or whatever. how can 1 make sure actions executed in kind of transaction maintain data integrity , safety? so thing remember rest "state transfer" bit. not telling server steps needed update resource, telling server state resource should in after update, because have updated on client , transferring new state on
