i'm having frustrating issue trying use linq call string manipulation method. i've done lots of searching , have tried various method line noted 'fails' below work. throws exception. some things i've tried: a) creation of concatenated key in same query, didn't change anything b) converting non-string fields strings (another whole can of works .tostring not working in linq. string.concat , string.format tried, work ok in cases not when try refer value later on) c) using concat etc instead of '+' join things together. as can see seems tolerant of appending strings non-strings, not when method invoked. there lots of rows i'd prefer not convert data list/array etc, if that's option suggestions appreciated. many thanks! - mark var vouchers = v in db.vouchers select new { v.amount, v.due_date, v.invoice_date, ...

i have simple regex task has left me confused (and when thought starting hang of them too). want check string consists of 11 digits. regex have used /\d{11}/ . understanding give match if there (no more , no less than) 11 numeric characters (but understanding wrong). here happens in irb: ruby-1.9.2-p136 :018 > "33333333333" =~ /\d{11}/ => 0 ruby-1.9.2-p136 :019 > "3333333333" =~ /\d{11}/ => nil ruby-1.9.2-p136 :020 > "333333333333" =~ /\d{11}/ => 0 so while appropriate match 11 digit string , appropriate no-match 10 digit string, getting match on 12 digit string! have thought /\d{11,}/ regex this. can explain misunderstanding? without anchors , assumption "no more, no less" incorrect. /\d{5}/ matches foo12345bar ^ +---here and s123456yargh13337 ^^ ^ |+---here | +----here | here--+ so, instead use: /^\d{5}$/

i creating restful service needs return collection of items, needs allow filtering several indexes (location, company, , category). these filters can applied individually or in combination. situation using filters applied in query string make sense? (some like: /items?company={}&location={}&category={} ) there better way pass filters resource? the preferred way pass search parameters use query string (indeed, that's why it's called query string). path identifies particular resource want (an index of items). query string may include, e.g., filter conditions, used alter how resource represented - still same resource (an index of items), path should same.

i'm new git, , using centralized workflow, similar svn. i'd periodically know status compared central repo. example, if run following commands... $ git clone git@github.com:centralrepo/test.git $ cd test; <make changes inside test/> $ git commit -a $ git pull ...git pull says "already up-to-date". why doesn't git pull report changes, , if that's correct behavior, there way know local out of sync remote? git pull fetch changes made in remote repository yours, equivalent svn update . however, not mention if there changes made @ end not on remote. can git fetch fetch updates remote without applying them workspace. with recent versions of git (e.g. 1.7.2.3 here) git status print information see this, e.g.: # on branch master # branch behind 'origin/master' 20 commits, , can fast-forwarded. this showing after did git fetch , means there changes waiting go workspace (applied doing git pull ) by contrast, if pull in , ma...

what i'm trying take user-inserted text cell , convert morse code, write result different cell. can't figure out how write result, current code saves last character in morse code array changed in output string (if exists in input string). m number of characters in both arrays. for = 1 m output = replace(input, a$(i), b$(i)) next range("output") = output if understand question correctly think problem you're overwriting output in each iteration of loop. try changing code to: for = 1 m output = output & replace(input, a$(i), b$(i)) next range("output") = input note added output & tells append new value output rather overwriting it.

i have error in nginx error.log: 2010/12/05 17:11:49 [info] 7736#0: *1108 client closed prematurely connection while sending client, client: 188.72.80.201, server:***.biz, request: "get /forum/ http/1.1", upstream:"http://***:3000/forum/", host: "***.biz" i have 500 response code on site everytime. how can fix this? thank you. i tackled problem myself long hours today , found solution: please note fix affects when using load balancer(s) check load balancer idle timeout. had elb idle timeout set 60 seconds (default) , request hanging, closed connection after given time. elb before nginx, nginx logging "client" (in case elb), closing connection. so if using elb, go to: ec2 -> load balancers -> select correct 1 -> scroll down in description , change idle timeout if using other load balancers, check configuration , timeouts. also keep in mind still might needing change proxy timeouts etc.

i have several databases located in different locations , central database in data center. have same schema. of them changed(insert/update/delete) in each location different data including central database. i synchronise data in central database. data in central database synchronise locations. mean database change in location 1 should reflected in location 2 database. any ideas on how go this? just @ symmetricds . data replication software supports multiple subscribers , bi-directional synchronization.

i have following table structure: event_id(int) event_name(varchar) event_date(datetime) event_owner(int) i need add field event_comments should text field or big varchar . i have 2 places query table, 1 on page lists events (in page not need display event_comments field). and page loads details specific events, need display event_comments field on. should create table event_id , event_comments event? or should add field on current table? in other words, i'm asking is, if have text field in table, don't select it, affect performance of queries table? adding field table makes larger. this means that: table scans take more time less records fit page , hence cache, increasing risk of cache misses selecting field join, however, take more time. so adding field table make queries don't select run slower, , select run faster.
