URL and FORM variables

i have page passes url variable second page. on second page form needs call itself, same variable name passed in url variable. is there way reuse name of variable, going url.variable form.variable after first usage? i not sure if explaining well, here example. page 1 lookup page - can search database name or id number. page 1 uses url variables give name or id number page 2, information displayed. reason page 1 uses url variables because uses cflocation statements based on outcome of search. at top of page 2 there lookup form can search. form calls page 2 well, time needs use form variables instead of url variables. since variables need passed same form, have same names (except form. instead of url.something) i didn't write original page - updating , adding it. suspect might better off rewriting section of page 1 calls page 2, i'm not sure. advice? my first instinct continue using url variables. change method of form "post" method="get". form submi

Serial write time

hi, i trying reduce time taken serial.write(...) function. theoretically, time taken function should 9 / baudrate send 1 byte. used following code verify : code: [select] void setup(){   serial.begin(115200);   serial2.begin(300); } unsigned long t; int i=0; void loop(){   if(i==0){     t=micros(); // line a     serial2.write(byte(5));     serial2.flush(); // line b     t=micros()-t; // line c     delay(50);     serial.println(t);     i++;   }   else{     if(i==1){       t=micros();       i++;     }     else{       if(micros()-t > 1000000){         i=0;       }     }   } } this code sends byte every 1 sec , prints time taken between line , c. problem when comment line b, time taken instruction "serial2.write(byte(5));" 20µs, every baudrate... when uncomment line b, time taken approximately 20 + 9/baudrate µs every beaudrate. in opinion, because first line copying byte write buffer, , second waiting sent. 1) assumption right ? 2) why take long copy byte (20µs !) ?

Static Holding force

i'm hoping control static holding force of full size autogyro simulator. motor gearbox automatic door closer (heavy duty stallable motor, built in encoders, drivable, 1deg backlash). joystick spends of time around neutral point being able control static force important. i'm anticipating either using current draw and/or strain gauges measure force feedback. the original controller worked @ 20khz , kemo #m171 pwm (spec sheet 10-20khz) controller seems work well. i've been told best way control holding force use both forward , reverse pulses. before attempt reinvent wheel advice forum have on selection of arduino; motor driver chip (max 10a); setting , controlling pwm frequency/pulse length; feedback loop; etc. any advice gratefully received. is "holding force" intended stop simulator sliding around on floor? how motor used? ...r Arduino Forum > Using Arduino

Text Weight Curiosity

so… knocking around in dreamweaver development center trying out few tutorials , came upon laying out list of font weights (100, 200… 900) see did. found of course, there 2 font weights 9 choices assume these supported in future browser versions. i did find, ie (no surprise) , opera (somewhat surprised) rendered 600 weighted fonts extended width while ff & ns did not.

CRON ne fonctionne pas !? - Raspberry Pi Forums

bonjour, après trois jour d'essais je craque !!!!!!!!!!!! cron ne fonctionne pas . j'ai essayer des centaines de tuto rien n'y fait. * * * * * php -f /home/toto/control_home/timer.php >/dev/null 2>&1 * * * * * /usr/bin/php -f /home/toto/www/control_home/timer.php >/dev/null 2>&1 * * * * * /usr/bin/php -f /home/toto/timer.php >/dev/null 2>&1 en ligne de commande cela fonctionne très bien mais ce foutu cron que dalle. en root comme en user en ligne de commande cela fonctionne. ma config est pi2, raspbian (firmware et update à jour), ngnix, mysql, php5-fpm, phpmyadmin, php-cli. grep -w cron /var/log/syslog ------> may 23 11:37:40 toto /usr/sbin/cron[3668]: (cron) startup (fork ok) may 23 11:37:40 toto/usr/sbin/cron[3668]: (cron) info (skipping @reboot jobs -- not system startup) le status dit running ok si quelqu'un pouvait me venir en aide ce serait super merci. cron ne fonctionne pas . tu fais bien de nous p
