we have database against run unit tests components require database (for several reasons not mocking dal everywhere). we using sql server 2008 r2 , in development db server have our development database (applicationname_dev) , our testing db (applicationname_ut). the unit tests create test data need , delete afterwards tables could/should empty when no tests running. the problem keeping schema of unit test database date. the best solution me (to limited knowledge) have sql server agent job run once night (or when manually started) drops tables in ut database, generate create script tables, indexes , relationships in dev-database, , run create scripts on ut-database. note don't need insert data. is there way of programmatically (t-sql, smo etc) generating create scripts tables including indexes , relationships ? in management studio can right click database->tasks->generate scripts...->choose objects->tables , scripts want (except "use [applicationn...

i have list of project objects: ienumerable<project> projects a project class property called tags . int[] i have variable called filteredtags int[] . so lets filtered tags variable looks this: int[] filteredtags = new int[]{1, 3}; i want filter list ( projects ) return projects have of tags listed in filter (in case @ least tag 1 , tag 3 in tags property). i trying use where () , contains () seems work if comparing against single value. how compare list against list need match on items in filtered list ?? edit: better yet, that: var filteredprojects = projects.where(p => filteredtags.all(tag => p.tags.contains(tag))); edit2: honestly, don't know 1 better, if performance not critical, choose 1 think more readable. if is, you'll have benchmark somehow. probably intersect way go: void main() { var projects = new list<project>(); projects.add(new project { name = "project1", tags = new int[] { 2,...

i making twitter type of website (not big twitter:), without using twitter api), have decide kind of database should use , how maintain in consistent state. the main problem: suppose website twitter clone(that make question easier understand), if have user "a" has 100 friends , friends tweet same time "a" logs in @ point in time tweets fetched database, database being updated friends tweets => database in inconsistent state q1> best solution it? maintain 2 database, use multi-threading etc? can explain in detail. q2>what best database particular usage. twitter uses nosql database called cassandra. take closer here: apache cassandra

this repost statistics portion of stack exchange. had asked question there, advised ask question here. here is. i have list of data-frames. each data-frame has similar structure. there 1 column in each data-frame numeric. because of data-requirements essential each data-frame has different lengths. want create boxplot of numerical values, categorized on attributes in column. boxplot should include information data-frames. i hope clear question. post sample data soon. sam, i'm assuming follow this question? maybe sample data illustrate nuances of needs better (the "categorized on attributes in column" part), same melting approach should work here. library(ggplot2) library(reshape2) #fake data <- data.frame(a = rnorm(10)) b <- data.frame(b = rnorm(100)) c <- data.frame(c = rnorm(1000)) #in list mylist <- list(a,b,c) #in melting pot df <- melt(mylist) #separate boxplots each data.frame qplot(factor(variable), value, data = df,...

i'm studying microsoft wf samples , have found serializing/deserializing workflows not finished hold state. don't workflow process , doesn't need additional data continue different thread or code part. maybe i've missed something. can share examples of saving/loading unfinished workflows if it's possible? maybe alternative workflow frameworks can without serialization/deserialization. example restored business object state. you're thinking far small. there many uses beyond can imagine right now. workflow frameworks (unless use type of object db?) serialize workflow state can continued @ later time. microsoft wf, k2 blackperl , many others this. k2 because can have item going through workflow v1 , right in middle update workflow v2 k2 smart enough know should continue processing item under v1 workflow. maybe i'm missing question seems don't serializes workflow storage.

my gut tells me advanced nhibernate users against , have been looking actual analysis on , have found nothing, i'd answer address these questions: what pros/cons of using it? there performance implications, both or bad (e.g. use call stored procedures?) in scenarios should use/avoid it? should use/avoid it? basically, reasons use/avoid , why? createsqlquery exists reason, executing queries either: not supported hard write using of other methods. of course it's last choice, because: it's not object oriented (i.e. you're thinking of tables , columns instead of entities, properties , relationships) it ties physical model it ties specific rdbms it forces more work in order retrieve entities it doesn't automatically support features paging but if think it's needed particular query, go ahead. make sure learn other methods first (hql, linq, queryover, criteria , get) avoid doing unnecessary work.

in c++ ios project (or other mac os), there simple way of making value available both info.plist settings, , code in form of preprocessor macro? ideally, have this c++ code: #define my_version_string "1.0" info.plist cfbundleversion: ${my_version_string} or alternatively, there way of getting values .plist in c++? (without manually parsing .plist xml.) probably not best solution, use /usr/libexec/plistbuddy utility in build script generate .h file containing define value extracted plist. to output value plist: /usr/libexec/plistbuddy -c 'print :path:to:key' filename.plist

i'm trying track position of robot overhead webcam. however, don't have access robot or environment, have been working snapshots webcam. robot has 5 bright leds positioned strategically different enough color robot , environment isolate. have been able using emgucv, resulting in binary image 1 below. question now, how positions of 5 blobs , use positions determine position , orientation of robot? i have been experimenting emgu.cv.videosurveillance.blobtrackerauto class, stubbornly refuses detect blobs in above image. being bit of newbie when comes of this, i'm not sure doing wrong. best method of obtaining positions of blobs in above image? i can't tell how emgucv in particular, you'd need translate calls opencv emgucv. you'd use cv::findcontours blobs , cv::moments position of blobs (the formula middle points of blobs in documentation of cv::moments ). you'd use cv::estimaterigidtransform position , orientation of robot.

lets there activerecord class called user, representative of user table of database. but have different type of users have special functions special variables custom relations (employer has_many companies, employee belongs_to company :) but these users have lot of functionality in common. want create classes each different type of user inherit them user class. user < activerecord::base employer < user employee < user customer < user what best way of doing that? thanks a lot of applications start out user model of sort. on time, different kinds of users emerge, might make sense make greater distinction between them. admin , guest classes introduced, subclasses of user . now, shared behavior can reside in user , , subtype behavior can pushed down subclasses. however, user data can still reside in users table. all need add type column users table hold name of class instantiated given row. active record takes care of instantiating kind o...

preface: i'm trying prefetch content given set of urls asynchronously. i'm needing send node.js app around 40-60 local ajax requests in order add jobs queue ( node-chain-gang ) client-side. right now, have making requests @ once, , either node.js app can't handle or it's not possible many @ once, ends crashing or requests not make through in proper order. i've tried using settimeout in between each request no avail (in timely manner). is there other way of queueing these requests/connections asynchronously client-side? or there more efficient way this? just queuing such small number of requests should not problem node.js. either have come across bug in node-chain-gang or have bug in code. if can narrow down code simpler version same behavior , post here.
