Sync to USB before unmount
by Mark Rogers 02 May '19

02 May '19

I have a script which writes data to an SD card connected via USB, then umounts it. The data is several GB in size so it hangs at the umount stage while the writes complete, and I want to give user feedback. (Note: I have had no luck whatsoever using sync to force the data to sync first, it always returns immediately.) At the moment I send umount into the background and grep /proc/meminfo for a "Dirty" value which I display, repeating until the umount command closes. This is reliable and fairly meaningful, but because it takes a few minutes is throwing a kernel INFO message into syslog: INFO: task umount:17976 blocked for more than 120 seconds Ideally I would just wait for writes to complete before even trying to umount, but I can't see a way to do that. Is there a way to determine if (say) /dev/sdc is still busy, and if so how much data is pending? Or any other suggestions? Current code (modified a bit for clarity in posting): echo -e "\n\nWaiting for writes to complete" sudo umount /dev/sdc[1-9] & while jobs -r | grep 'Running' > /dev/null ; do pending=$(grep -Po 'Dirty: *\K.*' /proc/meminfo) echo -ne "\rBuffer remaining: ~$pending " sleep 1 done echo -e "\rUnmounted - you can now remove the disk.

Local mirrors
by Bev Nicolson 30 Apr '19

30 Apr '19

I've swapped to Cinnamon Mint on a laptop (much better) and it's asking me whether I want to use a local mirror for updates. I've goggled so I now know what they are. What I'd like to know is, are there any downsides to using them? Bev.

LMS physical volume control for players
by John Cohen 21 Mar '19

21 Mar '19

Hi all I've got a logitech media server (LMS) setup with pi's all over the house that can synchronise playback from spotify and my personal music library. I use tablets & phones to control volume of the different players, as well as a Mycroft instance I can ask music requests and basic playback commands. All good so far... I'd love to have something physical like a remote control or better a dial/potentiometer on a wall to control volume on each player. Controlling the players with wifi is easy: some simple commands via http on any browser is all it takes: http://arduino-projects4u.com/squeezebox/ Can anyone thing of a creative/cheaper solution that avoids having to buy arduino shields & boards to achieve something like a physical knob or remote for volume control? cheers John

DNS Provider recommendations
by Karl Foley 19 Mar '19

19 Mar '19

Long time subscriber, but not a huge contributor! It's come to that time of year again when my domain needs to be renewed. Turns out Daily was taken over by TSOHost since my domain was renewed three years ago. Not really had any issues, but initially thought the renewal invoice was a scam. I got a bit miffed when the renewal invoice was for more than I could renew the domain on their website for. Not really looking for the cheapest, just something that is reliable for hosting my GSuite linked domain. Any recommendations please? -- ATB, Karl

Profiles woe
by Bev Nicolson 12 Mar '19

12 Mar '19

I'm still wrestling with this I'm afraid. When I try to start Thunderbird on the laptop it says it can't find the profile (renamed) though there should be one for it to use. I'm not sure how it isn't linked. How do I fix this and do you need more info? I have not touched Firefox. Bev.

What's the easiest way to copy bits of several PDFs onto one page?
by Chris Green 06 Mar '19

06 Mar '19

I have a multilingual manual for a new tractor mounted mower. It's almost unreadable because the 'multilingual' is done by having five columns of text (one of each language) down the pages. So I thought it would be easy to scan just the English columns and paste them together, five columns to a page, to make an English only version of the manual. It's not at all easy! There are very few programs that will 'merge' PDF pages and those that do seem to assume one is just trying to pack two or four complete PDF pages onto one sheet to save paper. So can anyone suggest how I can do this? I can very easily scan the English bits as required, what I need is a handy tool for putting a number of scanned images onto a page. I was trying to do this using PDF but it may well be that other file types would be easier, I can scan to JPG, TIFF, PNM, etc. easily enough. -- Chris Green
