we're start project using mentioned libraries. have used jqm in project, coupled backbone. we're thinking using angularjs jqm. think it's idea? , if not, why? to elaborate, question whether advisable/recommended/easy/beneficial use these libraries together, or maybe there should prevent using them both in 1 project. don't want spend half of project's time on making them work on principle. angularjs , jqm different things. angularjs mvc + lot more. jqm on other hand direct ui manipulation (lower level angular). news angularjs flexible , let work other javascript framework including jqm. recommended way of using them use adapter mentioned above or create own reusable directives add "jqm nature" views. e.g. can create directive convert standard ul fancier jqm list. thing doing in directives , not within view ui code separated in separate modules , not intermingled business logic.

i need implement undo-redo feature in application, reads project file , makes sequence of separate transactions changing project's content. project can hundreds mb large. my idea implement undo-redo on basis of copy-on-write (page_writecopy) memory mechanism. assume after end of transaction application can access both changed , unchanged pages, compare them, identify changed records, store original record states in dedicated undo stack, free created non-changed pages , restore write-on-copy protection of changed pages. have 2 questions: how , can found addresses of original (non-changed) pages. the awaited performance of such implementation?. middle size of project's records cira 100 bytes. if transaction changes 3000 records may involve change of 100 or more 4k physical pages. write-on-copy memory performant enough support routineous change of hundreds physical pages on each step?

i have problem understanding how works out : struct main_s { char test[1]; }; is 2 dimensional array test[1][x] ? example how pass string "hello world" field of structure ? char array[1][11] = { {"h","e","l","l","o"," ","w","o","r","l","d"} }; and main_s->test = array doesn't work, compiler gives error types, 1 char [] , char*. how pass string "hello world" field of structure ? you have first declare sufficient memory space test array contain desired string. "hello world" contains 11 charachters. array should contains @ least 12 elements struct main_s { char test[12]; }; and copy string array with: struct main_s m; strcpy(m.test, "hello world"); printf("%s\n", m.test) // display content of char array string if want declare 2d array: struct main_s { char test[3][13]; } struc...

i working on project management program, built on lamp stack. have tentatively chosen not provide each 1 of clients own database, rather combine business' data 1 large database. the first column in database tables business_id. row indicates business piece of data belongs to, keeps exposing business 1's data business 2. but try iron out billing kinks, useful able run cron job once month determine how database space each business using. here's question: there way mysql return number of bytes used rows business_id = 'x'? since billing information customer explicitly paying store, sum lengths of fields explicitly give you. (omit internal fields business_id , service_level_id , permissions , or whatever.) then, refer storage requirements , calculate. so, b number of bytes required numeric fields, , there 3 text fields txta, txtb, , txtc, instance: select business_id, count(*) * b + sum(length(txta) + length(txtb) + length(txtc)) b...

we have aging client/server based application clients connect directly our transactional database (ms sql server)... 99% of our business logic located in stored procedures. we've been toying around building servicestack api on top of existing database. eventually, we'd migrate business logic servicestack api , make sole entry point crud operations. makes sense in head except reporting , searching. my question this... allow crystal reports / excel / etc connect directly database pull data - makes writing reports flexible can join tables and/or write subqueries produce desired results. how comparable accomplished when make our servicestack api entry point database? is possible allow robust searching through servicestack api or there technology give same flexibility (joins, subqueries) , application tool build these reports in? thanks. i divide question in pieces , try give answer. if want single endpoint using servicestack api , have database ready he...

the xcode maven plugin http://sap-production.github.io/xcode-maven-plugin/site nice maven plugin people maven , wan't avoid pain xcode dependencies, framework creation , such. it creates , installs lib , headers in repository. the headers bundled in .tar file during process. for reason, need edit tar file , add few files in before installing. i'm quite noob regarding maven, need ! how can modify on byproduct of maven before installed ? suppose can write script add files .taf, how can sure it's executed prior installation ? @redwarp - it's been while since question asked, i'll offer answer. you can configure maven plug-in's goal executed during particular phase in maven build lifecycle. pick phase that's executed before install phase. package may best phase edit tar file , add required files. the following generalized example (the focus should on phase , goal): <project> ... <build> <plugins> ...

i'm working numbers far large php handle (ipv6 addresses in binary), work around i've formulated function convert addresses to/from binary strings (literally string of 1s , 0s). however, when comes subnet calculations easiest way know how use binary math. have no idea how i'd use binary math in instance since i'm technically dealing strings, not binary numbers. there way can binary math string representation of binary number? when working large binary numbers use gmp extension . accepts strings of arbitrary length parameters.

i'm trying select column highest value each row in data.frame. instance, data set such. > df <- data.frame(one = c(0:6), 2 = c(6:0)) > df 1 2 1 0 6 2 1 5 3 2 4 4 3 3 5 4 2 6 5 1 7 6 0 then i'd set column based on rows. data frame this. > df 1 2 rank 1 0 6 2 2 1 5 2 3 2 4 2 4 3 3 3 5 4 2 1 6 5 1 1 7 6 0 1 i imagine there sort of way can use plyr or sapply here it's eluding me @ moment. there might more efficient solution, ranks <- apply(df, 1, which.max) ranks[which(df[, 1] == df[, 2])] <- 3 edit: spaced!
