.net - Why is my RFID reader reading an unexistant RFID tag code? -


our team developing software application read rfid tags using mc3190z rfid handheld reader. using emdk .net v2.9 , visual studio 2008, testing , deploying directly device.

this reader showing unknown rfid tag code in every single reading process, if there no tags around antenna range. epc code present: a7423000ad47240312719f756e0000f0

this process repeats either using our application, or using standard applications such rfid rapidread/rfid demo/tag locator (downloaded motorola website).

we though related sort of stored or default information stuck in our reader, using right mechanism use reader capabilities described in documentation. did cold , hard reset our device trying fix problem nothing worked.

any or comments around welcome.

interestingly, issue may are, in fact, reading existing rfid tag.

i'm not sure if still case but, in past, strap shipped mc3190-z rfid device contained uhf rfid tag embedded within it. when first received our handheld, attached strap , started reading rfid tags; however, state above, kept reading single tag on , on again. no matter how isolated mc3190-z device, read same rfid tag.

as turned out, reading uhf rfid tag came embedded strap. once removed strap, fine. if using strap, remove it/isolate it, , see if helps.

altneratively, can set program filter out particular tag id, shouldn't have that.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
