I have the map of US in my cell-phone. I'm somewhat confused by its directions however when I look at the map and want to go somewhere. Is the top-part of the map where I'm moving? Or is the top-part North? Seems it is not North and that is confusing because maps I've seen before have North at the top always. If I turn 90 degrees, the map turns around. But I thought it was I who turned around. And if I stop, the map…

I really hate that too. You are in a intersection and the voice says "Drive north for x miles/km". What is wrong with "turn right and drive for x miles/km"? I normally have zero clue in what direction north is especially when I am in a location i have never been before. I drive a bike and have the phone in my pocket and can therefore not see any arrow that the app might display. I only have the audio to navigate from…

It will do that if it doesn't already know what direction you're travelling, which is usually because you've just activated navigation and you aren't moving yet. Unless I happen to know which direction north is or which way to towards my destination I'll just pick a random direction and it will adjust the route if I guessed wrong.

PDF is a fabulous format. I mean, it’s an awful format in so many ways, technically speaking, but the net effect of having a self-contained static file in your custody stands in blissful contrast to the user-hostile dynamic/SaaS website that can be taken away at a moment’s notice. PDF/A is the true PDF - it strips out most of the dangerous cruft. Anyway, if you like weird PDF hijinks, here’s a polyglot PDF/A CSV file…

PDF is an executable file. Many people are worried about running Javascript but still use PDF files without problems.

about pdf/a... until recently there was not even an easy way to figure out if pdf is really pdf/a; now there is (verapdf) and it's crazy complex piece of software

and maybe I'm wrong but the only way to convert arbitrary pdf to pdf/a with open source software is to convert it to postscript and back with ghostscript - which is affero licensed... with all the possible problems it entails. (there is old version that is just gpl, works on most pdfs but is 15 years old or such.)

i needed to deal with pdf/a in a previous job... was not fun.

Yeah but the javascript can only do things inside the pdf.

What javascript can escape my browser, (edit: or an HTML page) for example?
