If you get rhis error message even you have all the rights, probably you are trying to run the command on a mounted partition that had the “noexec” flag on.
So change partition, .f.e. try your /home.
tag object in firefox
It’s probably a bug, but you couldn’t manage to view an svg object tag with firefox, unless is setted as image/svg (and not a text/svg).
mysql wrong autoincrement number
It can happen that the ID autoincrement goes wrong; in this case my solution is very simple: I delete the ID column, and afterwards I re-create it (with the same parametres). It works.
ancient greek in LibreOffice
a simple maquillage, unfortunately
I mean ancient greek font so that you can, typing ‘a’ get immediatly ‘α’. So far the free most interesting true type font (the only recognised by LibreOffice) is SPIonic.
caveat
Absolutely to avoid the “AncientGreek” extension: cumbersome, useless and very aggressive (after removing leaves you with modified shortcuts, including some basic like ctrl + z, ctrl + b and F3).Vey bad!
a new solution
I noticed that the above solution works only within LibreOffice: if you copy a greek word in another program, you get a no-greek text (with latin encoding). That’s why I call it now a maquillage.
A possible, better solution is go to a website that easyly encode your text in ancient greek, such as this.
keeping updated your custom css (in Calibre viewer or in markdown-viewer browser extension)
You can link within the css (in Calibre it is within the file “viewer-webengine.json”, in markdown-viewer browser extension is the css file you yourself have chosen) your external css file, with something like
@import url(http://localhost/path-to-your-css-file/your-css-file.css)
Provided you have a apache/php server in localhost, of course.
linux. how to get images from a (short) video
You can use this code:
ffmpeg -i [nameofthevideo] -r 10 -f image2 image-%3d.jpeg
where 10 after -r is the number of images per second. So you can change it, according to your needs.
linux: keep open the terminal
you can add at the end of your command ;bash
for example:
rclone sync mega:ebooks /mnt/zippati/ebooks/ebooks/ -l -v ;bash
alternative browsers
I’m very disappointed by Midori and Epiphany: too minimalist.
libreoffice via snap: not a good idea
Discover let you install the latest LibreOffice release, but:
- it is very much slower than a no-snap realease
- no mysql-connectr available
Not a good idea!
So, I removed it: sudo snap remove libreoffice.
phpmyadmin: add a table (or a view) to “favorites” (bookmarks)
In tables (or views) click on the star next to his name.
