Re: BASIC - more harmful than useful?

Interesting discussion - since kids themselves are actually being programmed as early as they can understand language: IF BEHAVE=TRUE THEN REWARD ELSE TREAT_DENIED. Kids that see that connection, will become programmers... or advertising executives. LOL!

Re: SD image too big for another SD Card

You're aware that SD card sizes vary anyway ?. They can't manufacture them all perfect so they size the cards afterwards and block out any bits that don't work. Some will have more bits blocked out than others so the size varies slightly. Theres nothing wrong with the resize option in raspi-config ...

Re: SD image too big for another SD Card

Ouch! I've been checking my half dozen "identical" 16GB SD cards, all RiData 16GB class 10's and they ALL work fine, HOWEVER... They do NOT end up formatted to the same size as each other !! I do believe that after using the raspi-config option to 'resize partition' to use the full SDcard, many peop...

Re: You wanted MPEG-2? You've got it!

Re: You wanted MPEG-2? You've got it!

I strongly suspect the license key email is being created by a keygen program written by a lazy programmer who inputs the email address and cpu serial number and has the keygen create a small text file (without passing along the relevant serial number or numbers) and emails it directly using SMTP. ...

Re: OpenELEC, XBMC - Cannot get wifi working.

If you are really stuck then you can connect temporarily by ethernet and download an add-on that will detect your ssid and step you through the configuration. Similarly you can connect to the device via ssh when it is wired into your router. Rob, What add-on (to detect my ssid and step me through t...

Re: Problem flashing micro SDXC card

Try bs=4m (lower case m, not M). AS for disk1 being busy, just make sure you've got the right disk and are not trying to wipe your Mac system disk by mistake. Good warning! Earlier this week, I plugged an SDcard into my desktop and fired up SDformatter and didn't notice that it found letter H, not ...

What's a "dlsr"? Something new I hadn't heard of? Is it one of the things in this list? http://www.acronymgeek.com/DLSR I especially like your idea that it should create a wi-fi hotspot even if it can't connect to the net.

Re: Monitor not detecting Raspberry Pi

I had this same problem, but I tried a second, very small 7" HDMI monitor and it DID work, so then I checked my big monitor's settings and discovered it was set fixed to DVI instead of AUTO. I changed the big monitor's setting to AUTO and the next time I started the Pi, the monitor worked just fine....

Re: Safety concerns

Counter intuitive in the sense that overclockers desperately try to cool down the CPU of the PC they are trying to overclock, and it seems they are trying to make it much cooler than a normal system is.

Re: Safety concerns

Tip for those interested, the hotter the device the faster it gets (which is a bit of counter intuitive, but true.). Obviously it also -ages- faster when it does. Counter intuitive? As conductors heat, the molecules vibrate faster and electrons are more easily knocked loose and electrical resistanc...
