Setup §įor the migration to be done, you will need a few prerequisites: Prosody documentation: Prosody migrator 2. The switch to SQLite drastically reduced prosody CPU usage on my small server, and went pain free. Recently, I got more users on my server, and I wanted to improve performance a bit by switching from the internal storage to SQLite.Īctually, prosody comes with a tool to switch from a storage to another, but I found the documentation lacking and on OpenBSD the migration tool isn't packaged (yet?). My server is running Prosody XMPP server on OpenBSD. Tags:Īs some may know, I'm an XMPP user, an instant messaging protocol which used to be known as Jabber. Migrating prosody internal storage to SQLite on OpenBSD PDF are usually a pain to work with, but pdftk make it very fast and easy to apply transformation on them. Pdftk have some other commands, most people will need to extract / merge / rotate pages, but take a look at the documentation to learn about all pdftk features. Pdftk input.pdf cat end-1 output reversed.pdf If you want to reverse how pages are in your PDF, we can use the special range end-1 which will go through pages from the last to the first one, with the sub command cat this will only recreate a new PDF: If you want to select even or odd pages, you can add the keyword even or odd between the range and the rotation direction: 1-10oddwest or 2-8eveneast are valid rotations. Pdftk input.pdf rotate 1-endeast output rotated.pdf If you want to rotate all the pages of a PDF clockwise (east), we need to specify a range 1-end, which means first to last page: You can specify pages or ranges of pages to rotate, the whole document, or only odd/even pages etc. Pdftk comes with a very powerful way to rotate PDFs pages. Note that they are concatenated in their order in the command line. Pdftk first.pdf second.pdf cat output merged.pdf In the following example, you will concatenate the PDF first.pdf and second.pdf into a merged.pdf result: Merging multiple PDFs into a single PDF also uses the sub command cat. Pdftk my_pdf.pdf cat 11 16-18 output export.pdf Pdftk command line isn't the most obvious out there, but it's not that hard.Įxtracting a page requires the cat sub command, and we need to give a page number or a range of pages.įor instance, extracting the pages 11, and from 16 to 18 from the file my_pdf.pdf to a new file export.pdf can be done with the following command: The graphics and ambiance is amazing considering they are using a modified Doom engine.I often need to work with PDF, sometimes I need to extract a single page, or add a page, too often I need to rotate pages.įortunately, there is a pretty awesome tool to do all of these tasks, it's called PDFtk. The developer spent a lot of time dialing in the game so it was a challenge, but still possible to have fun. I love the levels, interaction, crafting and action mechanics.
