i looking hash function save on storage space while storing lot of duplicate strings in database. i have db have store date rate description xxx yyyy zzzz 100s of millions of rows; description max 1k string. description string has high repeat; many duplicates. avoid (wasted) storage thinking of doing this table 1 date rate desc_id table 2 desc_id description approach 1: desc_id == md5 hash --> db has primary key on descid; app generates hash; db writes fast (that thinking) approach 2: desc_id == db generated id; unique key has description; db writes might slower above approach. question1: should stick md5 or there better algos out there? worthwhile go sha-x functions theoretically better collision avoidance, while taking hit on storage d compute time? question2. should consider going approach 2?

r - Rd2pdf - special (and German) characters -

-
yesterday used rd2pdf convert documentation of r package pdf , discovered special characters '§' , german umlauts (ä, ö, ü) not displayed. i'm using debian 7 , have texlive installation - latex documents use packages 'ngerman' display special german characters ä, ö , ü , ß . so, rd2pdf uses whole latex thing, question is: is there way include these additional packages enable rd2pdf displaying these special characters? thanks in advance! the following works on ubuntu 14.04 system: r cmd rd2pdf --encoding=utf-8 file.rd see command-line text r cmd rd2pdf --help ... the rd sources assumed ascii unless contain \encoding declarations (which take priority) or --encoding supplied or if using package sources, if package description file has encoding field. output encoding defaults package encoding 'utf-8'.

i quite new big android world. going through first app go easy on me. there lots of api levels , lots of devices , think makes lots of hard stuff on android. so questions :- which minimum api level should choose , why ? which virtual device should start - there lots of options available ? should check ui every time when make changes on devices ? thanks. appreciated :) 1) there 2 ways here. right (2014/09) can go sdk 10+ or sdk 15+ . sdk 10 still has 12% of total active users. indicated here: https://developer.android.com/about/dashboards/index.html?utm_source=ausdroid.net supporting api 10+ pain, requires using lot of backports , compatibility libraries. you're in luck! it's pretty safe develop on sdk 15+, can see dashboards cover close 90% of devices. 2) can use genymotion . it's free small developers , beginners. can use native emulator it's laggy, if use intels hax , gpu rendering decent. have here. 3) yes , no. should develop best devi

ios - Is application bundle fully replaced on upgrade from App Store? -

-
the following use case: create strings file (not localized) , deploy application test device localize file (en.lproj or similar), make changes new file , remove original file deploy application on device what noticed (always?) application still use old non-localized file. reason apparently file still in somewhere application bundle, though has been removed project. ios's logic if file of specific type looked up, first checks in root of bundle non-localized version, , if doesn't find go deeper localized folders. (is me, or logic kind of backwards? i'm used first looking language specific file, , falling defaults, might java background.) sometimes (always?) removing app device doesn't either. in case cmd+shift+k, cleans build folder, , after app built , deployed again, correct file used. a worse problem if such thing leads app crash, strange issues nibs or whatever - have seen well... the question is: happen if first version of app in apple store had non

angularjs - How do I code a custom ordering function in angular? -

-
having <div class="item" data-ng-repeat="course in courses | filter:filtercourses | orderby:predicate">... and $scope.predicate = function(course) { //$scope.orderprop }; what code need put inside predicate can order same way default orderby:predicate order(not sure if makes sense) place empty course.startdate @ end of list notes: course object different properties title, startdate, code $scope.orderprop contains value sort by: title, startdate, code. when startdate empty place items @ end of list still keep sorting date properly, start date "integer" later display ng-date in nicer form thank you answer: here's ended http://jsfiddle.net/3hz2j8j7/ orderby can accept list of predicates (a bit saying "order a, b"). first predicate ensure blank start dates go @ end, , second 1 use value of orderprop: <div ... orderby:[nonemptystartdate, orderprop]"> $scope.nonemptystartdate = function

javascript - for var index in vs. forEach -

-
in javascript, if want loop through every element in array, have several methods that: 1. for(var =0; i<array.length; i++){} 2. array.foreach(function(item, index){}); 3. for (var index in array){} the first 1 common one, if feel lazy, want use second or third one. but wonder if there's difference between them, , in situation should choose which? they subtly different approaches. for(var = 0; i<array.length; i++){} tried-and-true method; feels c, works c. iterates on every array index , without corresponding property/item. works on object supporting .length , properties names [0..length); while works on sparsely-populated arrays additional guard may required. unlike foreach , allows use of continue/break/return manual adjustment of index within loop body, if such ever required. array.foreach(function(item, index){}) approach prefer because sufficient, feels cleaner, , "lazy" . iterates on every array value/index that ha

ios - -[NSDateComponents week] deprecated, which enum gives same behavior as before? -

-
the documentation nsdatecomponents says of ios 7, week deprecated , use weekofday or weekofyear instead. if want same logic got when used week , of these should use? i have used in many places in code, thinking through each scenario cumbersome. if there 1 enum mapped same thing week did, save lot of time. didn't find in documentation, have in code: nsdatecomponents *todaycomps = [calendar components:nsyearcalendarunit | nsmonthcalendarunit | nsweekdaycalendarunit | nsweekcalendarunit fromdate:[nsdate date]]; when printed todaycomps.week console got 39. so think should replace todaycomps.week todaycomps.weekofyear. don't forget use nsweekofyearcalendarunit instead of nsweekcalendarunit. good luck!
