trying eject usb external hardrive terminal (hence thread name). (the external harddrive ntfs-3g format). terminal commands+output: 10:54{~} umount /media/cerberus umount: /media/cerberus not in fstab (and not root) 11:01{~} eject /media/cerberus/ umount: /media/cerberus not in fstab (and not root) eject: unmount of `/media/cerberus' failed 11:01{~} have no idea go here. unmounting nautilus filebrowser works fine (right-click, "unmount volume"), unmounting terminal gives fstab error. two issues going on here. first, terminal, need use sudo or root in order umount drive. second, umount , eject commands expecting device work with, i.e. /dev/sda or /dev/sdb. so, first thing in terminal, type: sudo fdisk -l ( -l lower case l, not 1 ) output give /dev of external usb hard drive, likely: /dev/sdb1. if case, type: sudo umount /dev/sdb1 unmount drive. hope helps.

is there way can rename column within coldfusion query? i've attached example. i've joined table same table here , have named them , b. want able rename columns in b that, when display output, not have same names in a. (eg. b_pkgname , b_pkgrev). brandi l wrote: > there way can rename column within coldfusion query? yup , in other technology making use of sql supports alias 'as' statement. i.e. select a.site, a.pkgname, a.pkgrev, b.pkgname b_pkgname, b.pkgrev b_bkgrev ... i hear things ben forta's "teach sql in 10 minutes" as many sql references , tutorials available on internets.

hi, i wondering why have use pinmode declaration in sketches. if use analogwrite or digitalwrite command specific pin, doesn't imply particular pin output? , if use read versions of similar command, doesn't imply opposite? thanks quote doesn't imply particular pin output? using analogwrite(), yes. using digitalwrite(), no. might turning pullup resistor on input pin. quote and if use read versions of similar command, doesn't imply opposite? pins default input, read works without need use pinmode(). in fact, though, can read state of output pin. so, digitalread() rells nothing state of pin.

greetings forum first question: have raspberry pi 2 , want power using 4 2800 mah rechargeable aa batteries , read online when connected in parallel mah adds up, if so, can implement increase pi's life on batteries? if not, last 3.5 hours? given pi draws 800 mah. second question: want connect rechargeable batteries 5v solar panel whilst powering pi, how can prevent batteries overcharging. there way measure how full batteries either through pi, or through connect battery case whilst in use? know it's possible because phones it. there no type of battery give satisfactory results if connected directly rpi. rpi should fed 5 volts +/- few percent. 4 nimh aa cells series manage when freshly charged fall low , give short run time. need ubec between battery , rpi. easiest solution use 1 of usb powerbanks intended recharging mobile phones or tablets. of them have solar panels built in. panels near large enough produce enough current run rpi without depleting battery. if opt

i'm hoping on here might able help, i'm using mosfet http://canada.newark.com/vishay-siliconix/si2302cds-t1-e3/mosfet-n-ch-20v-2-6a-sot-23-3/dp/69w7186?ost=69w7186 for pwm'ing 12v leds in project. i'm curious stepping being able use 24v leds 12v , hoping might have part number on hand small mosfet (ideally in sot23 casing) can handle max voltage above 24v, , has suitable properties running via pwm. thanks looks you'll have move bigger package.  if need more one be aware there dual mosfets in soic8 package like: http://canada.newark.com/vishay-siliconix/si4910dy-t1-ge3/dual-n-channel-mosfet-40v-6a/dp/26r1895 Arduino Forum > Using Arduino > General Electronics > Help finding right MOSFET arduino

in pidgin, have enabled message notification plug-in, , have enabled set window manager "urgent" hint. there way of adjusting window manager flashes more frequently? currently, doesn't flash; changes color darker lighter darker. please let me know if there can do. thank you! this happens more pidgin. panel's "urgent hint" being set, , *think it's part of active theme. when application requests user attention, fades in/out in same way. think 1 of irritating things in ubuntu; taskbar fades when "urgent hint" active. no good, , not indicate "urgent". glance @ screen across room, , soft slow fade not cut it. know how make stop fading , blink boldly? nice know if can set flash frequency. sure can't find out how, after searching.
