Adding all users to the "disk" group: bad idea, or terrible idea?
by Stewart C. Russell 22 Feb '20

22 Feb '20

So I'm working with a developer making a simple cross-platform graphical program to write Raspberry Pi OS images to SD card. This is meant for beginners to use. The developer is adamant that their program doesn't need to run under 'sudo' but that every user should be added to the disk group instead. This means that every user can write directly to system disk devices at any time. The Debian-based systems I use don't add regular users to "disk". Is it reasonable/common for regular users to be set up this way? cheers Stewart $(export HAVE_ACCIDENTALLY_OVERWRITTEN_ROOT=1) Russell

Finding current cursor position in the terminal
by Giles Orr 19 Feb '20

19 Feb '20

I'd like to be able to get the current x,y (or row, column) position of the cursor in a terminal. This is for a Bash or ZSH prompt, and my intention is to calculate how far across the terminal we've printed and then decide if we should wrap the prompt from one to two lines. There's a terminal escape sequence to do this: echo -e '\033[6n' or: tput u7 These output the desired information in some form of extremely difficult-to-parse code (works on Mac or any Linux, I think). The output looks like this: ^[[24;1R The numbers are line and column respectively. If you search the web, you can find various code (usually using the builtin 'read' command) to parse this. And some of the answers work fine ... in this context, ie. running it as a stand-alone command. But wrap it in a prompt and things go straight to hell. export PS1="--\$(echo -en '\e[6n')-- " You'll find that some of the output appears after the prompt, as part of the input line. Any attempt to 'read' and parse the value within the prompt hangs or returns empty, or does something else weird. My guess (uneducated and wild as it is) is that the escape sequence doesn't complete until AFTER the prompt is displayed. Because it's waiting for some magical code the prompt provides? I have no clue. One or two of the pieces of code I've found do parse the result and return properly ... but then they always return "1" for the column ... (they usually get the row right). And I'm primarily looking for the column. I've spent a lot of time searching for a solution, and trying all kinds of weird Bash coding tricks, with no particular luck. Does anyone have any idea how this might be handled? This is just one of many, many half-complete examples I've tracked down. The questioner eventually provided his own answer: https://stackoverflow.com/questions/43911175/get-current-cursor-position-wh… but what I found was that it always returns 1 for the column ... The author didn't care because they were only interested in the line number. Any help appreciated. -- Giles https://www.gilesorr.com/ gilesorr(a)gmail.com

Intel GPU support for HDMI 2.0 (UltraHD)
by D. Hugh Redelmeier 12 Feb '20

12 Feb '20

It seems that 7th gen and later Intel processors can support HDMI 2.0, but only with an external "LSPCON" (Level Shifter and Protocol CONverter) component on the motherboard. See <https://www.intel.com/content/dam/support/us/en/documents/graphics/HDR_Inte…> As I've mentioned before, going through DisplayPort also works and does not require a LSPCON.

interesting way ransomware broke into Windows systems
by D. Hugh Redelmeier 10 Feb '20

10 Feb '20

<https://www.tomshardware.com/news/robbinhood-ransomware-gigabyte-driver-cyb…> A security failure by Gigabyte and another by Verisign. Maybe the Linux world is better without manufacturer support.
