Hello, The class Python for Beginners - Part 1 will be held on Wednesday, October 04, 2017 at 16:00 UTC in the channel #archlinux-classroom on the freenode network. The class is expected to run for about 2 hours. This class will introduce you to programming with Python and how to use IPython with an editor/IDE. Commonly used built-in functions and libraries will be explained. Other topics will explored based on participant interests. The class will be screen-shared live (via YouTube), and later archived with subtitles. Questions and some discussion on IRC is expected, however the main part will be video and audio. In preparation for the class, install the Jupyter notebook. ``pacman -S jupyter`` or, in a Python 3 virtualenv, ``pip3 install jupyter``. Also check out the python-beginners git repository on Arch Classroom's GitHub[1] where you will find IPython notebooks and links to useful resources on learning Python: https://github.com/archclassroom/python-beginners pulec is an Arch Linux user since 2012, gamer and gardener.

[arch-general] Thunderbird doesn't show e-mails
by Giovanni Santini 30 Oct '17

30 Oct '17

Hello everyone, I have a weird issue. My uni e-mail uses Office 365 as e-mail provider; I've added it in Thunderbird, but I can see only unread e-mails. All the read one are not appearing in my inbox. However, if I `cat` the INBOX file, I can see the e-mails and if I mark them as unread from somewhere else I can see them. Also, adding the e-mail address on Thunderbird on Windows doesn't have the same problem. Any idea to further investgation? -- Giovanni Santini My blog: http://giovannisantini.tk My code: https://git{hub,lab}.com/ItachiSan My GPG: 2FADEBF5

[arch-general] Weird artifacts after every pacman transaction
by Chorom Potro 28 Oct '17

28 Oct '17

Hello, Couple of days ago my power was cut in the middle of an update (pacman was updating purpose and atk), after the failed update my system would not run any app because libpurpose and libatk was corrupted. So I did a force reinstallation of both. Now everything is working but after each transaction I am seeing a bunch of texts like these: ldconfig: File /usr/lib/libavdevice.so.57 is empty, not checked. ldconfig: File /usr/lib/libavformat.so.57 is empty, not checked. ldconfig: File /usr/lib/libswscale.so.4 is empty, not checked. ldconfig: File /usr/lib/libavcodec.so.57.107.100 is empty, not checked. ldconfig: File /usr/lib/libswresample.so.2 is empty, not checked. ldconfig: File /usr/lib/libswresample.so is empty, not checked. ldconfig: File /usr/lib/libswscale.so.4.8.100 is empty, not checked. ldconfig: File /usr/lib/libpostproc.so is empty, not checked. ldconfig: File /usr/lib/libavutil.so.55.78.100 is empty, not checked. ldconfig: File /usr/lib/libpostproc.so.54 is empty, not checked. ldconfig: File /usr/lib/libavformat.so.57.83.100 is empty, not checked. ldconfig: File /usr/lib/libavutil.so is empty, not checked. ldconfig: File /usr/lib/libavcodec.so.57 is empty, not checked. ldconfig: File /usr/lib/libavresample.so.3 is empty, not checked. ldconfig: File /usr/lib/libavfilter.so.6.107.100 is empty, not checked. ldconfig: File /usr/lib/libavcodec.so is empty, not checked. ldconfig: File /usr/lib/libavutil.so.55 is empty, not checked. ldconfig: File /usr/lib/libswscale.so is empty, not checked. ldconfig: File /usr/lib/libswresample.so.2.9.100 is empty, not checked. ldconfig: File /usr/lib/libavformat.so is empty, not checked. ldconfig: File /usr/lib/libavfilter.so.6 is empty, not checked. ldconfig: File /usr/lib/libavresample.so.3.7.0 is empty, not checked. ldconfig: File /usr/lib/libavdevice.so.57.10.100 is empty, not checked. ldconfig: File /usr/lib/libpostproc.so.54.7.100 is empty, not checked. ldconfig: File /usr/lib/libavdevice.so is empty, not checked. ldconfig: File /usr/lib/libavfilter.so is empty, not checked. ldconfig: File /usr/lib/libavresample.so is empty, not checked.

With all programs above I can scan - right. I can also make an PDF of the scan. With gscan2pdf I can scan many pages at once (fledbed scanner or ADF) and convert all pages directly to PDF. In addition, OCR is performed. And a pdf is generated with the text from OCR as hocr layer. The special feature is that a searchable PDF can be created at once. As far as I know it is not possible with simple-scan nor with scanlite nor with gambas3-gb-scanner. The special thing is that I can correct then OCR Text directly before I save the file. And a few other things that simplify the work. It is not just another scan program. It is the only program I know what allows archiving in this way. best regards Stephan

[arch-general] RAID10 + dmcrypt/LUKS + ext4: expanding?
by L. Rose 25 Oct '17

25 Oct '17

Hi everyone, I want to setup a couple of drives using RAID10 with mdadm. On top of /dev/md0, I want to setup one large dmcrypt/LUKS encrypted ext4 volume. As Arch wiki reads, this seems to be possible. But what about expanding that volume later on? RAID#Format_the_RAID_Filesystem recommends calculating the stripe_width value for ext4 based on the number of data disks[0]. When adding a new disk, the number of data disks would increase by one, and expanding both the dmcrypt/LUKS and the ext4 layer should be possible - but what about the stripe width_value? Does it need to be updated? Should it be updated? Is it possible to update the stripe_width value afterwards? Encryption is a must for me, and having the space accessible in one big chunk instead of individual disks would allow more efficient usage and is therefore important for me. So it would be really nice to get some information on this. Thanks in advance! Regards, L. Rose [0]: https://wiki.archlinux.org/index.php/RAID#Example_3._RAID10.2Cfar2
