Lately ocrmypdf keeps failing when I just wanna compress pdfs so had to do it without fail. Also to clean metadata was using ExifCleaner but didn't realize all metadata can be restored by doing exiftool -pdf-update:all= some.pdf.
qpdf does a decent job of compressing images and the linearize destroys the metadata that was stripped out so it can't be restored.
exiftool --list some.pdf will show pdf metadata
On Mac (cuz of stupid zsh)
metapdf=$(bash -c 'read -e -p "Input pdf filename to clean metadata and compress: " tmp; echo $tmp') && exiftool -all:all= $metapdf && qpdf --linearize --object-streams=generate $metapdf ${metapdf%.*}_cleaned.pdf
On Linux this should work
read -p "Input pdf filename to clean metadata and compress: " metapdf && exiftool -all:all= $metapdf && qpdf --linearize --object-streams=generate $metapdf ${metapdf%.*}_cleaned.pdf
Another way to compress pdfs is
ps2pdf in.pdf out.pdf but it's way too slow
On Linux I use MasterPDF Editor to crop pdfs but on Mac not sure what free app there is so resorted to online pdf croppers. Only free one I found that doesn't destroy bookmarks in the process was pdfmonk but gotta use it in Safari.

Telegram auto-delete message, expiring invites, and more
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
The seemingly negative pandemic effects and resource/product shortages are encouraging and allowing organizations to innovate and change.The news of cash-rich organizations getting ready for the post-Covid growth economy is a sign of more than capital spending plans. Cash provides a cushion for risk-taking and a tool for growth.
