Re: Raspberry Pi Compute Module Reformat
Hi, My compute module is not able to get past early in the boot stage. I believe I may have corrupted the disk image in the file transfer, and I would like to redo everything. How do I erase everything I did and start from scratch? Thanks Why are you not able to grab the latest Raspbian image, your...

Re: Forgot password
Surely you're not suggesting that enforcing ignorance will ensure ethical behavior? Ethics and knowledge are two different things. You are essentially arguing against teaching owners about single user mode on the basis that such knowledge might be used for evil. I'm not 'suggesting' anything, and d...

Re: Forgot password
I go as far as to say that kids should be taught how to hack their own passwords with commonly available tools as soon as possible. What better way to spread security awareness? That is an interesting idea... one I had not thought about for a while until I read the blog and saw the video with the c...

Re: Poll of the Week III
Technically, headless is a NOT display type... more precisely headless is an interface type, which is really what the poll was after although 'interface type' would have better granularity. With a 'headless' setup I may interface only with gpio (or not) or I may interface with some lame Internet pro...

Re: Forgot password
Mark, in re-reading this thread, it strikes me that we may have had a fundamental misunderstanding. You wrote something to the effect that "on-line helps with password recovery are off-limits", which is a little ambiguous. Did you mean the information shouldn't be on-line, or that the system being ...

Re: gpio_slew and gpio_hysteresis?
Read the datasheet for your particular sensor. If you can read the datasheet as pdf all the better; you can 'find' "hysteresis" throughout the document.
You might also want to try googling for 'hysteresis' and read-up!

Re: Forgot password
[...] The trouble is that people 'humans' generally don't take security seriously, and they generally view their password (or security) as an inconvenience rather than a friend. Security is a responsibility, not an inconvenience. I don't disagree, but I'd also point out that you can buy highly secu...

Re: Headless with WIFI
You can use ifconfig to get the mac address of your wifi adapters. Then in the config of your router|dhcp server you can reserve an IP address for those mac addresses. In other words, when the router|dhcp server sees the wifi adapter connect it will assign the 'same' address (effectively a static ad...

Shift will only work with NOOBS. But you can always recover a password by adding init=/bin/bash and it will skip the login prompt.

Re: Using a raspi2 SD card in a raspi1 B model?
Can I directly plug an SD card that was used in a raspberry pi 2 and use it in an older model (raspi1 model B)? I didn't want to try because I wasn't sure if booting up the SD card in an older raspi would screw up something... Thanks! :) I don't think it will bonk anything, but I don't think it wil...

Re: Forgot password
Connect a TV/monitor, keyboard & mouse. Hold the [SHIFT] key while booting and the NOOBS recover system will start. You can use that to edit cmdline.txt to boot your Raspbian system to single user mode or a root shell. no no no, you responded too quickly... let things simmer a bit... allow it to so...
