by accident tried estimating relative position of image (don't ask). expect result of 0 translation , 0 rotation. surprisingly, non-zero translation result. in fact rather significant result: .0825 -0.0825 . in essence code follows: cv::point2d pp(u0, v0); cv::mat r, t, mask; cv::mat e = cv::findessentialmat(points1, points2, focal, pp, cv::ransac, 0.999, 1.0, mask); cv::recoverpose(e, points1, points2, r, t); in above code, t != 0. question is: non-zero result recoverpose valid when points1 , points2 identical? if so, why? from decomposeessentialmat documentation: "by decomposing e, can direction of translation" and translation vector constructed in such way norm of translation equal 1.

imagine following data: peter santos (sa) john doe - sa maria santos i match strings containing letters sa, not if they're inside word. in other words, when evaluating "peter sa ntos ( sa )", should fail on " sa ntos" since it's succeeded other letters, succeed on ( sa ) since there no letters preceding or succeeding it. "john doe - sa " should match sa entry there... "maria sa ntos" should not return since it's succeeded other characters. how achievable using ms sql without using regex? i believe query logic gives need without using regex: select string_to_search<br/> ...<br/> <br/> string_to_search 'sa[^a-za-z]%'<br/> or string_to_search '%[^a-za-z]sa'<br/> or string_to_search '%[^a-za-z]sa[^a-za-z]%'<br/> the 3 predicates in clause allow 'sa' appear @ beginning, middle, or end of string, neither preceded or followed letters.

is there additional configuration needs done in order enable cdi jta transactions using @transactional annotation under cdi beans weblogic 12.1.3 server? i have tried add annotation service method, entitymanager didn't recognize running under transaction. is there interceptor or else needs registered? @joshament right. weblogic 12.1.3 partially supports java ee 7 (it supports 4 pieces: jpa 2.1 , jax-rs 2.0 , json-p 1.0 , websockets 1.0 ). @transactional part of jta 1.2 . right liberty profile certified against java ee 7. planned year-end weblogic 12.1.4 going support also. anyway, answering question: configured persistence.xml should enough use @javax.transaction.transactional annotation in code. // may consider move away java ee 7 ;) able freely choose whatever lib want. believe server should not provide except servlets.

i have project (written in ruby) want run in docker image. project source code stored in private git repo, image created usual dockerfile. project huge , git clone takes relatively long. the problem that, i'm not sure how (when/where) clone git repo docker image properly. can clone git repository temp directory , copy source code copy command in dockerfile. don't since have maintain second clone in temp dir. or, can clone repo within docker image. problem ssh-key can't reasonably keep in image. can add "my own" keys git server allow access everything. so, created script this: uuid=`uuid` docker run \ -v $home/.ssh:/home/user/.ssh:ro\ --name=$uuid \ -it $1 /scripts/git-clone-update.sh docker commit $uuid $1 docker rm $uui git-clone-update.sh clones project if doesn't exist or updates if does. keys mounted .ssh that. works great. can update code in image calling script passing image name argument. problem config.cmd changes /scripts

recently have migrated ssrs sql server 2005 2012 running on windows 8. deleted encryption key after observing reporting server inaccessible. able access reporting server internet explorer on same machine, , able list existing reports in browser. when try open report, login name , password required before viewing report. expected behavior reports should opened without necessity provide login/password. question: caused deletion of encryption key? how solve it? go datasources reports , check credentials stored against them. may need resave these credentials create new encryption key. click 'test connection' see if successful. your reports should work fine once have re-established safe connection between report , server.

by default resharper folder's "namespace provider" property defaults true. want property false. means, every zillon times create new folder in projects have set manually false. is there way make resharper folder's "namespace provider" property false default? my answer not default value. it's workaround. these settings stored in yourproject.csproj.dotsettings file each folder in project. if "namespace provider" set false yourfolder , following record added file: <s:boolean x:key="/default/codeinspection/namespaceprovider/namespacefolderstoskip/=yourfolder/@entryindexedvalue">true</s:boolean> so may make list of of folders using total commander or similar tool , add file, or automatically. hope helps!

this question has answer here: increasing (or decreasing) memory available r processes 4 answers i have 16gb ram machine windows 64 bit.if run model in r uses 2gb , remaining memory free. have run same model in 4gb machine takes 4 hours give result,so upgraded 16gb ram ,but still r takes same 4 hours run same model in 16gb machine also.r not using more 2gb of ram. any idea why r not using entire ram avaiable. on 64-bit os, handling 16 gb of ram should no problem r. configuration-issue prevents r doing so. you can check current memory-limit calling memory.limit() (see http://www.inside-r.org/r-doc/utils/memory.size ). can use memory.limit(12000) set new limit. but should check whether ram limiting factor. if doing number-crunching, increasing ram not speed calculation of result.

i using ffprobe on windows identify files. command/parameters use are: ffprobe -show_entries format=format_name -v quiet filename i noticed image files ffprobe reports different format if file name has (or not have) , extension. example, bmp image file named xxx ffprobe -show_entries format=format_name -v quiet xxx reports [format] format_name=mp3 [/format] but, if rename file xxx.bmp , rerun command ffprobe -show_entries format=format_name -v quiet xxx.bmp reports [format] format_name=image2 [/format] is behavior expected? has else encountered issue? using recent version of ffmpeg.

i have dataframe variables coded integers, i'd replace actual value labels. for example, have following dataframe: >>> df=pd.dataframe([[1,3],[2,2],[3,2]], columns=['q1','q2']) >>> df q1 q2 0 1 3 1 2 2 2 3 2 if, numbers 1,2,3 represented same value in both columns, have dictionary looked this: labels={1:'yes',2:'no',3:'unsure'} and recode applymap: >>> df.applymap(labels.get) q1 q2 0 yes unsure 1 no no 2 unsure no however, integers code different label in each column. example, dictionary of value labels may this: labels2={'q1':{1:'yes',2:'no',3:'unsure'}, 'q2':{1:'very', 2:'a little', 3:'not @ all'}} what efficient way of recoding values in scenario? i using apply , loop (see below), pretty clunky. there better way? >>> import pandas pd >>> dfs=[] >&
