Darktable 2.4.3 and GIMP 2.10
by Andrew Greig 06 May '18

06 May '18

Hi All, Darktable 2.4 came out a little while ago and GIMP 2.10 is hot off the press, and now that GIMP supports 32bit image depth it makes sense for them to work together. And, in fact, they should as GIMP, when confronted with a RAW file indicates that either Darktable or RAW Therapee can act as the RAW file processor. So how do I get them to work together? I was expecting a field in DarkTablepreferences saying "External Editor = GIMP" and in GIMP, something like "RAW image processing by Darktable". But I have found nothing like these at all. Any clues?? Please. Andrew Greig

Mail filtering with rspamd
by Jason White 30 Apr '18

30 Apr '18

I've recently turned to rspamd 1.7.1 as my antispam solution. So far, it seems to be effective, but I've only been using it for a day or so. Interestingly, the latest version offers neural network-based analysis, which is probably the right direction for development to be taking (as one factor in making the classification decision). I also found that I could eliminate a lot of undesirable SMTP connections by setting reject_unknown_client_hostname in the Postfix configuration. My host is well connected with good DNS resolution, so I assume that any errors in this regard are probably due to the client host's not being a legitimate mail server. Comments and suggestions for further improvement are welcome.

Technical challenges of CV maintenance
by Jason White 10 Apr '18

10 Apr '18

For various reasons, I need to maintain a CV, and, moreover, several different versions of it to meet different requirements. At the moment, it's written in Markdown, maintained in a Git repository, and uses Pandoc for conversion to various file formats (e.g., PDF via LaTeX, HTML, Microsoft Word/OOXML, etc.). Unfortunately Pandoc's Markdown does not support conditional inclusion/exclusion of parts of the document (e.g., a switch or if/then/else construct). I'm faced with the prospect of maintaining several different files, and of manually migrating changes between them - a good recipe for mistakes. A Web search reveals that one solution is to set up a preprocessor to perform the conditional inclusion/exclusion operations on the Markdown file. This is cumbersome, but achievable. There may be a Pandoc filter available somewehre that can do the same. Another solution would be to switch the document to LaTeX format. From memory, there's a LaTeX package for conditional inclusion of material in documents. I'm also quite comfortable with LaTeX, so it would be a question of choosing a good LaTeX class for use in CV writing, but which would also convert cleanly to HTML. Latexml seems to be the currently maintained LaTeX to HTML conversion tool. There may be other options that I haven't considered. If anyone on the list has been here before and has suggestions to offer, these would be welcome.

Accounting software
by Mark Trickett 05 Apr '18

05 Apr '18

Hello All, I have a friend who has been stuck on Windows because of being tied to being able to hand his accounting data to the accountant in a Tax Office approved format, which has meant Quicken/QuickBooks or MYOB. I am not so certain of legal requirements, but what double entry accounting packages are there, and are any approved? I do know of GNUCash, but not the current status, and is it available for him to play with first on Windows. I an constantly annoyed by the insistence that only commercial packages are valid, when the quality of the coding is demonstrably dubious, let alone whether there are any "back doors".

reload /etc/network/interfaces with out rebooting
by Geoff D'Arcy 04 Apr '18

04 Apr '18

Back in the good ole days before we had systemd I could edit /etc/network/interfaces and have networking restarted by doing a start stop on /etc/init.d/networking. But with systemd this doesn't seem to work. As well as running # /etc/init.d/networking restart I've tried # systemctl restart networking.service # service networking restart And the above commands with an explicit start then stop instead of restart. But any changes made to etc/network/interfaces aren't applied. On the survey the commands above appear to be doing nothing. I'm not using network-manager but resolvconf is installed and is populating /etc/resolv.conf, although only after a reboot. In the systemd world how do you restart networking with new settings with our rebooting? thanks in advance.

Kde volume control
by Russell Coker 30 Mar '18

30 Mar '18

I've done a fresh install of Debian/Testing on a new laptop and the volume control buttons aren't working. They make no apparent difference to the volume and no change to the volume settings according to alsamixer. It seems that the backend is "Phonon VLC". Is it possible to have KDE use ALSA directly without such things? Is there another desktop environment that has a more minimalist design without being like TWM? I want something that has notifications for USB devices, battery, network manager, etc but not too much else in the way of trying to take over everything and not having a process like plasmashell taking 10% of a CPU core when nothing is happening. -- Sent from my Huawei Mate 9 with K-9 Mail.

For sda2 (ext3) I made the mistake of testing random creates / stat / delete which ran all night and then some, just soaking up CPU.
