Assuming the EPUB file is unencrypted, how can I append pages of text, or an image, to an EPUB file, programmatically/via script?
My goal is to keep my own notes inside of the EPUB file for maximum transportability. In years past, I've lost notes and highlights made in EPUBs as I change EPUB reading apps.
Currently, when I'm done reading an EPUB, I export the EPUB file and all EPUB highlights (using some highlights exporter apps).
Using a few GUI apps, I confirmed that I can manually add my notes to an EPUB file. But, I'd like to have this done programmatically/by script.
I would want added pages to be visible in an EPUB reader. I'm fine with placement before the cover, or at the very end of the book.

I am creating a MacOS application to take an audio file chosen by the user and display its sound waves in a timeline. Like the one below.
I have searched Google and Stack Overflow for a few hours and only found IOS examples. Every time I tried to take one and convert it to work with MacOS there were conflicting libraries used.
If you could provide me with some code to get started or a source/article that has information that would be great.
Thanks In Advance!
AudioKit can display waveforms using AKTableView. It is cross platform and there's an example of how to load files into one on of the framework's playgrounds, which is also shown online here:
http://audiokit.io/playgrounds/Basics/Tables/
The code is simple so even if you need to add to it, you can pull the necessary parts from AudioKit and place it in your own project, if you don't want to add all of AudioKit to your project just for this one feature.

This is a very beginner question, and I apologize if I sound stupid.
I want to make a website very similar to what facebook did for pride. Like this: https://www.facebook.com/celebratepride
I want to make my own transparency, and I don't want to use an image editing website, I want to have it all contained on my website.
Where do I begin? Is there some kind of engine that I can adapt and edit for something like this?
There are loads of image editing libraries out there. PHP's GD library will allow you to create images by combining elements. You will need to create a transparent PNG that you would combine with another image, as an example.
See this question and answer for more information
Merge two PNG images with PHP GD library
Ideally we would need to know what your preferred coding language is and what your server capabilities are in order to help you more.
There are probably some out the box solutions out there too, but I'm going with what I know on this one

Renaming filename without highlight extension in Mac [closed]

When I press return to rename a filename, automatically, the whole filename is selected (highlighted), including the extension. This is happening in some file types, including .SRT.
In most of the file types, this won't happen. They're most known file types, like JPG and TXT. I tried setting a default app to this file type but that won't fix the problem, I still get the whole filename (including extension) highlighted when press return (to rename the filename).
Any ideas?
Your system doesn't recognise .srt as a valid extension. You need to install an app that will "tell" to the operating system about this extension.
An app that did this for me was VLC

I have a documentation set that I need to deliver to a variety of users. It is currently in HTML with a number of attachments with a total size of around 180MB. I have the following requirements:
It only needs to be viewable on windows.
The user must not need to install additional software prior to viewing the documentation over and above what is normally on the machine (MS Office, browser etc)
The entire set needs to be searchable (preferably including MS Office attachments)
(desirable) It needs to be distributable as a single file (.exe OK)
(desirable) It needs a compatible authoring tool
Any ideas on what would be a good way to do this?
Way out of my area of expertise, and it may not work with the office files, but Microsoft Compiled HTML Help looks promising.
One tool that we are considering to do this is TiddlyWiki which allows inline editing of the source and can be extended with plugins to look more like a traditional website and to provide better support for multi user editing.

Tagged PDFs allow for the easy reflow and accessibility of PDFs. It seems like this would be a natural use case for using LaTeX, which advocates content over style. But as far as I can tell, there is no way to create a tagged PDF with MikTeX 2.8.
Does anybody know of any tips, tricks or techniques to get a tagged PDF through LaTeX without resort to the commercial version of Adobe Acrobat?
Hmm, well, yes, sort of.
There isn't really sophisticated support for tagging, and what there is, is implemented in pdftex/luatex. Support for bookmarks and in-document cross-references is done using tagging. There's also been some more sophisticated work shown at TUG conferences, but this is all in the pipeline for now.
Context/luatex has better support that Latex for this sort of thing: there's some support for interactive documents using Context's layers, where the contents of the layers change when buttons are clicked in the PDF. I think this must be done using tagging.
I've never heard of anything like embedded forms, digital signing, or embedding the Latex/Tex/Context source in the resulting PDF, but in principle this is all possible.
I've the same question with pdfLatex in general and found this:
http://sarovar.org/tracker/index.php?func=detail&aid=945&group_id=106&atid=495
But I don't test it till now.
