regex - Find entries with zero distance variance and recorded watts -


i'm cyclist , programmer. during rides, i'm recording data xml files using phone based gps tracker , power meter. after ride, use power meter software merge data , upload web site. on website, resulting data showing highly inaccurate data wr watts (it weighted average, known normalized power, definition higher average power , lower maximum recorded watts. see http://ridewithgps.com/trips/4834566 (export tcx history file i'm referring to). /<watts>\d{4,} returns no results.

calories:   1809 max watts:  676 avg. watts: 213 (170 0s) wr power    23487 work    1681 kj max speed:  26.2 mph avg. speed: 16.6 mph

here 2 sample readings tcx history file.

      <trackpoint>         <time>2015-05-30t11:35:50z</time>         <position>           <latitudedegrees>41.96306</latitudedegrees>           <longitudedegrees>-87.645939</longitudedegrees>         </position>         <altitudemeters>177.7</altitudemeters>         <distancemeters>71.5</distancemeters>         <cadence>67</cadence>         <extensions>           <tpx xmlns="http://www.garmin.com/xmlschemas/activityextension/v2">             <watts>104</watts>           </tpx>         </extensions>       </trackpoint>       <trackpoint>         <time>2015-05-30t11:35:51z</time>         <position>           <latitudedegrees>41.963076</latitudedegrees>           <longitudedegrees>-87.646094</longitudedegrees>         </position>         <altitudemeters>178.0</altitudemeters>         <distancemeters>75.7</distancemeters>         <cadence>67</cadence>         <extensions>           <tpx xmlns="http://www.garmin.com/xmlschemas/activityextension/v2">             <watts>156</watts>           </tpx>         </extensions>       </trackpoint>

i've reviewed every entry <watts>\d*</watts> corresponding cadence 0 (if i'm not pedaling, watts should zero).

:g/<cadence>0/.,+3s/<watts>[1-9]\d*/<watts>0/c

but did not resolve issue. next step find entries distance between tracepoints not change , contains wattage greater zero. returns e65: illegal reference

:g/<distancemeters>\(\d*\)/+1,+15s/<distancemeters>\1/

clarification:

i'm looking locations watts must 0 , not. these not pedaling (cadence = 0) , when not moving (consecutive distance nodes identical). i've corrected wattage cadence = 0, don't know how find consecutive <distancemeters>n</distancemeters> nodes n unchanged.

given enough determination, can done:

:%s/\m<distancemeters>\([0-9.]\+\)<\/distancemeters>\n\(.*\n\)\{1,15}\s\+<distancemeters>\1<\/distancemeters>\n\(.*\n\)\{3}\s\+<watts>\zs[1-9]\d*\ze<\/watts>/0/gc

however, why on earth want in vim?

angularjs - ADAL JS Angular- WebAPI add a new role claim to the token -

i have created angular spa webapi backend using adal js authentication.as there no roles in ad, need manually add role claims in order give users access different api controllers. the roles stored in database. expecting inject claim through call webapi after authentication ad. webapi code might this. identity.addclaim(new claim("role", "user")); var ticket = new authenticationticket(identity, props); var accesstoken = startup.oauthbeareroptions.accesstokenformat.protect(ticket); is possible replace adal idtoken new token? is viable solution or there other better way handle this? as initial token generated azuread, possible edit token add new claim? appreciated. graph api supporting group claims. see here: http://justazure.com/azure-active-directory-part-4-group-claims/ if @ examples on page, users assigned groups , app can check group in claims. in current version of portal, need app manifest , modify it.

i problem when make request (i can request). $link = 'http://uri/path/?param1=1&sid=2&sid=3&sid=4' $http = $httpsocket = new httpsocket(); $res = $httpsocket->get($link); if check request pr($http); i see : [line] => /url/path/?param1=1&sid%5b0%5d=2&sid%5b1%5d=3&sid%5b2%5d=4 http/1.1 and i'm getting empty response because server doesn't know parameters sid%5b0%5d=2 when try send parameters array : $data = array('param1' => '1', 'sid' => array('2','3', '4')); i see same changes %5b0%5d - additional indexes. how fix it? unfortunately , can not change server side, if send request in browser, i'll normal response in json format. when make request, can parameters this: $param1 = $_get['param1']; $sid= $_get['sid']; tip: use diferente names parameters. have multiples sid. use sid1, sid2, sid3... update: can parameters this:
