i'm categorizing few folders on drives , want weed out low quality files using regex (this works): xvid|divx|480p|320p|divx|xvid|divx|xvid|xvid|divx|dvdscr|pdtv|pdtv|dvdrip|dvdrip|dvdrip now filenames in high definition still have dvd or xvid in filenames 1080p, 720p, 1080i or 720i. need single regex match 1 above exclude these words 1080p, 720p, 1080i or 720i. you can use negative lookahead this ^(?!.*(?:1080p|720p|1080i|720i)).*(?:xvid|divx|480p|320p|divx|xvid|divx|xvid|xvid|divx|dvdscr|pdtv|pdtv|dvdrip|dvdrip|dvdrip) this match on search strings, fail if there 1080p|720p|1080i|720i in string.

are there webrtc libraries ported blackberry? if not, possible port android ndk code bb10 project? thanks in advance! webrtc free both paid , unpaid apps. currently, blackberry interested in delivering support webrtc , researching/investigating on technology. however, no dates or release schedules have been announced @ moment. depending on apis being used in android app. may or may not possible port android ndk code blackberry10. though android runtime not support webrtc projects, blackberry10 os built on qnx, compliant posix system. qnx compiler, qcc, has gcc-compliant mode port on existing code.

how host windows service in iis , keep service runing running on windows? use feature wcf service? i've not access windows itself, iis. inside service i'll create thread @ scheduled time process data. in short, can't. a more detailed answer there 2 problems: iis worker processes launched when http request comes in. means can't start service system. iis worker processes recycled (i.e. restarted) on several conditions. example, worker process restarted if no http request comes in long time. means can't control when service shut down, unless have access application pool recycling configuration. keep in mind recycling logic ensures pending http requests complete, not await background threads complete. you can come partial solution way: create wcf service method checks if long-running thread alive , if not, starts it. create very simple windows service periodically (once in 5 seconds) calls method. deploy service somewhere, e.g. on own machin...

we're using tfs our source control , we're facing following problem. has mapped projects differently. causing builds break(as person1 has project/file references different person2). pass around piece of paper mapping printed out, , seems bit antiquated. so question(s) is: where vs store mappings each user? is there way enforce have same mappings(or pass out file map same)? the mappings stored in tfs , on client, they're not 'enforceable'. can create workspacetemplate. option available command line (by default). see tf.exe workspace /new /template . but team foundation power tools add feature team utilities page of team explorer: then can instruct team members use workspacetemplate when setting workspaces. you can copy/paste workspace definition notepad , copy/paste visual studio (quite nifty). you create small workspace analyzer find broken workspaces. tfs object model can used query workspaces stored on tfs server.

i know cassandra offers atomicity , isolation batch mutations on row-level basis since version 1.1 ( http://www.datastax.com/dev/blog/row-level-isolation ) but these guarantees hold repair mechanisms (hinted handoff, read repair , node repair)? i'd guess these operations use batch mutations , 1 can therefore state these guarantees hold. don't know code , therefore can't prove or disprove point. i neither have found source tells me atomicity , isolation guarantees aforementioned repair mechanisms. so maybe of can give me source or can justify if these guarantees hold in these cases? kind regards stefan repair works @ sstable level, not individual mutations. since individual mutation not split across multiple sstables, same isolation guarantee during repair.
