i'm creating architecture of app , trying find best one. few words it: box solution (each app installed on customer's machine) there main app , gems extend (private) main app has default list of gem other functionality extending adding additional gems request (our gems) but customers no need full functionality, don't need include gems it's gemfile. what best way organize it? think way? maybe can offer more effective way? you may want consider making "main app" or core functionality a mountable engine , not rails application. that means packing controllers, models, , routes gem added stock rails application customized specific customer. how cms:es refinery , radiant structured. this allows full freedom each "box" have whatever settings , gems wants. important if intend let clients self host (which nightmare). it makes developing , updating core easier bundler resolve gem dependencies. add "default" gems depend...

i wish write this: select sum(weight) items itemid in (4217,4575,6549,4217) where itemid primary key, , sqlite , mysql process expected, i.e. add 4217-th row sum twice, don't. is there @ least in mysql i'm not aware of that's intended cases this? if not, workaround like? row can have number of duplicates in list. list can big although in cases small. i don't know out of box functionality can this. here workaroud. can insert values temp table , use join: create temporary table list(id int); insert list(id) values(4217),(4575),(6549),(4217); select sum(i.weight) items join list l on i.itemid = l.id;

the current solution working structured single core layer connecting database whenever needs retrieve data. i suggested few colleagues create dal layer , move of database logic it's own project , call application.dataaccess this layer use entity framework , repository pattern abstraction between application.core , application.dataaccess (the repository implementation sit within application.dataaccess). i plan to consume repository in service layer. public class jobservice { private ijobrepository _jobrepository; public jobservice(ijobrepository repository) { _jobrepository = repository; } public ienumerable<job> getjobs() { list<jobs_alljobs> alljobs = _jobrepository.getalljobs(); list<job> result = new list<job>(); foreach(job in alljobs) { result.add(new jobs() { title = job.title, otherentity = "internal service"; }); } return result; } } job r...

i'm writing script requires root level permissions, , want make if script not run root, echoes "please run root." , exits. here's pseudocode i'm looking for: if (whoami != root) echo "please run root" else (do stuff) fi exit how best (cleanly , securely) accomplish this? thanks! ah, clarify: (do stuff) part involve running commands in-and-of require root. running normal user come error. meant cleanly run script requires root commands, without using sudo inside script, i'm looking syntactic sugar. the $euid environment variable holds current user's uid. root's uid 0. use in script: if [ "$euid" -ne 0 ] echo "please run root" exit fi

is there way have foreach outside function body ex. generating code. my scenario have associative array @ compile-time need use generate specific fields. unfortunately can't use foreach outside of function body generate members. right using work-around have few mixins give 1 aa first mixin , mixin converts aa array , passes second mixin, second mixin recursive ng until there no more member, while calling first member in array, calls third mixin can use generate code. it's not smooth , dynamic want , wondering if has better solution. here solution // first mixin takes associative array , string mixin handle items mixin template staticforeachaa(tkey,tvalue, tkey[tvalue] enumerator, string itemmixin) { enum array = arrayaa!(tkey,tvalue)(enumerator); // converts aa array of key-value pair structs alias arraytype = keyvaluepair!(tkey,tvalue); mixin staticforeacharray!(arraytype, array, itemmixin); // calls second mixin array } // second mixin "fa...

i using firebase storage in android app , using getbytes method file. i want set param request unable find method add params. these params set automatically on download (we build download urls you), we're totally abstracted away networking. additional query params add? a better way of doing might attaching custom metadata file , checking custom metadata in rules .

i run loop: n = 10 alpha = 0.05 sigma = 0.01 (i in 0:n){ vt10[i] = ((sigma^2)/(alpha^2))*((n-i)+(2/alpha))*exp(-alpha*(n-i))-(1/(2*alpha))*exp(-2*alpha*(n-i))-(3/(2*alpha)) } however, vt10 outputs 10 outcomes (doesn't include first iteration, when i = 0 ). how can create vector include 11 iterations? answer: n = 10 alpha = 0.05 sigma = 0.01 vt10 = numeric(11) ## this! (i in 0:n){ vt10[i+1] = ((sigma^2)/(alpha^2))*((n-i)+(2/alpha))*exp(-alpha*(n-i))-(1/(2*alpha))*exp(-2*alpha*(n-i))-(3/(2*alpha)) } also, need vt10[i+1] , because loop 0 10, while array index should 1 11. comment: your code looks c code. not start index 0, write loop task. try: n = 10 alpha = 0.05 sigma = 0.01 = 0:10 vt10 = ((sigma^2)/(alpha^2))*((n-i)+(2/alpha))*exp(-alpha*(n-i))-(1/(2*alpha))*exp(-2*alpha*(n-i))-(3/(2*alpha)) in situation, there no need predefine vector. r knows performing element-wise computation, , automatically assign length-11 vector vt10 .

in django project, i'm using suds , logs predetermined log (suds.client) , doesn't let me configure different log messages. i'm trying around adding 1 of handlers have defined in settings.py. in code uses suds: logging.basicconfig(level=logging.info) suds_logger = logging.getlogger('suds.client') suds_logger.setlevel(logging.info) suds_logger.addhandler('my_handler') suds_logger.propagate = false this incorrect (because i'm passing string naming handler , not handler itself) , results in error: error:my_handler:'str' object has no attribute 'level' so, seems have correctly use 'my_handler' handler settings , should go. so, correct syntax?

the week of month not define value. shift between starting week , starting month causes problem in cases. is there python lib or algorithm calculate value? you can calculate looping on days of month , counting whether you've come across n th weekday: import datetime def get_n_weekday(year, month, day_of_week, n): count = 0 in xrange(1, 32): try: d = datetime.date(year, month, i) except valueerror: break if d.isoweekday() == day_of_week: count += 1 if count == n: return d return none for example: get_n_weekday(2016, 1, 1, 1) = first monday of january 2016 datetime.date(2016, 1, 4) . this uses date.isoweekday() means monday 1 , sunday 7.

i want store blobs outside of database in files, random blobs of data , aren't directly linked file. so example have table called data following columns: id name comments ... i can't include column called filelink or because blob raw data. want store outside of database. love create file called 3.dat 3 id number row entry. thing setup main folder start have large number of files id flat folder structure , there os file issues. , no data not grouped or structured, it's 1 massive list. is there java framework or library allow me store , manage blobs can myblobapi.saveblob(id, data); , myblobapi.getblob(id) , on? in other words file io handled me? simply use appropriate database implements blobs described, , use jdbc. not looking api specific implementation. it's db take care of effective storing of blobs.

assume have 2 types, t1 , t2 . t1 isn't important except following facts: it isn't copy constructible it has move constructor we have excellent function signature t1 copy(t1 const& orig) , creates copy. t2 can simplified following class: // t2.h class t2 { public: t2() { /* initializes vector */ } t2(t2 const& other); private: std::vector<t1> v; } // t2.cpp t2::t2(t2 const& other) : ... {} how implement method, if write ellipsis part, or global scope? a simple real world use case - assuming "you can't write between curly braces" part real world restriction: t1 std::unique_ptr<anything> copy std::make_unique anything has copy constructor i have 2 additional requirements implementation: performance. shouldn't (considerably) slower naive implementation for loop in copy constructor's body. readability. entire point behind question more clear/clean trivial loop (e.g. imagine t2 2 or mo...

i have 2 viewcontrollers inside tab bar controller. in interface builder, i've applied image insets (5, 5, 5, 5) tab bar icons sizes how want them. looks great when run simulator, when tab second viewcontroller, both tab bar icons automatically resize default (0, 0, 0, 0). when tab return first viewcontroller, both icons remain trapped @ default size no insets. note: icon images .pdf files in xcassets folder (set single vector scale factor). i've seen other threads suggest "balancing" insets (5 top, -5 bottom). compress image 5 away top , stretch 5 toward bottom. don't see how that's meant balance image size. if knows code set insets @ runtime, maybe use instead of setting insets in interface builder? in advance. reading documentation, uibaritem (superclass of uitabbaritem ) has property imageinset , , can access tab bar items via self.tabbarcontroller.tabbar.items . without testing myself, think may have issue insets getting reset...

im pretty sure has been asked before not know how phrase it. mods, maybe can collapse questions once compatible answer has been found? i have node.js server , send url read or write json data. node.js url parser seems characters "?" "#" , "&" reserved while in json.parse/stringify side """ , "'" reserved well. how can work around this? kind of song data , these characters can , come in title names. tia niko update: i forgot mention turned out crucial: in node side using url , querystring modules have own logic manipulating url. due url , querystring modules using in node parse url according own logic have opted treat query part of url stringified json. have end-to-end control on application , make sure url send has stringified json query part of url.

so have pandas dataframe containing column fields 'latitude' , 'longitude' , map function take 2 fields precision applied entire dataframe, , add column 'geohash' frame output of function being mapped. right i've been able implement hackish string concatenation having mapped function parse out args appropriately. @ least shows output i'm looking for. what have currently: def my_encode(argstring): argstring = str.split(argstring,'_') lat,long,precision = float(argstring[0]),float(argstring[1]),int(argstring[2]) try: hash = geohash.encode(lat,long,precision) except: hash = '' return hash precision = 7 data['args'] = data['latitude'].astype(str) + '_' + data['longitude'].astype(str) + '_' + str(precision) data['hash'] = data['args'].map(my_encode) its not terrible think more appropriate solution exists. in advance! iiuc can way...
