merging PDFs in batch with ghostscript (or something else)

Tue, 2018-03-13 23:25

I'm not sure that this is the right subreddit for this question, but haven't been able to found a more promising alternative.

I'd like to merge the pages of two PDFs, where PDF1 contains the the top of the page and PDF2 the bottom half. To put the problem differently: suppose that PDF1 of format A5 (or smaller) contains graphics and PDF2 of format A4 containing text and a frame as placeholder where the content of the matching page from PDF1 supposed to be placed. Any tips how to approach the problem? Perhaps suggestions for a better suited subreddit?

So please NOTE: I'm not looking for merging PDFs sequentially!

First off, im a noob.

I have run into the problem of my keyboard randomly not working in certain windows while working in others. For instance i can type in terminal but not in firefox. Sometimes there are different windows that dont work. Its odd. What might cause this?

Using kernel to ensure UDP timestamps are sequences before delivery to user space?

Tue, 2018-03-13 20:23

Hello all, ran into a strange issue with a legacy app thanks to the introduction of a wireless bridge. Basically we are getting packets out of order and the delivery protocol is UDP. I've been googling hoping to find a proc parameter or some type of iptables trick with no luck. Does anyone know if there is a way to ensure that the user space application receives the IP / UDP packets in order via relative to their timestamp? I realize buffering etc, that this gets complicated in a hurry .. in this particular case a drop is better than an out of order.

Thoughts or clues I might look at?

Thanks so much!

Edit: feeling like a dummy as I already knew this - UDP itself doesn't have a timestamp, only the payload in our case it doesn't have that either. I'll float the question anyhow in case some genius has an idea :D
