So there's yet another exploit for Acrobelfry....
Reminds me I haven't checked for updates in quite a while, what with it being a manual install.
And, look! I go to Adobe's site, and not only has the Acrobat reader (or whatever they're calling it these days) for Linux not been updated since version 9.5.something, but it's no longer available through the regular download path. (Version 9.5.5-1 still exists, but only if you know where to look.)
Yes, there are open-source programs for reading PDF files. They mostly work. In some cases, they work better than the Adobe product... especially when it comes to printing to a Postscript printer. (Adobe Acrobat has long been notorious for emitting output that Just Won't Work on a printer that uses Adobe Postscript. This isn't just a Linux thing; I first noticed it during my time in Corporateland when using a company-issued Windows NT system, back when NT was a thing.)
But... it seems none of them support all the funny features of the "Portable" (ha!) Document Format.
Not that I use any of the fancy unsupported features, but it's a potential work-compatibility issue.
And: none of them support having a gazillion files open in a single window, with a tab bar running along the bottom to select among them. This is how I use it. I tend to have quite an assortment of datasheets, manuals, client specs, and other assorted documents sitting open, all in a single window on virtual desktop #11, sandwiched between the web browser (desktop #10, typically several browser windows each with multiple tabs open) and the text editor (jEdit on desktop #12, with, at the moment, 474 files open, and a buffer-list sidebar to manage them).
So, do I need to grab the source code for one of the better open-source viewers, and write a more Adobe-like wrapper for navigation and open-document management? Office software really isn't my thing; I'm more of a bit-basher, and find GUIs rather baffling.
Actually, that might be a good idea anyway. Adobe's product has some weird bugs that show up when it's used the way I use it; after a while, the UI becomes horribly and inexplicably sluggish (like taking a minute or so to open a file or print dialog, while not using significant CPU time, so what's it doing?); I don't know if this is a function of time or of the number of files that have been open, but it's highly annoying.
