  • I know PDF providers who visibly print the customer’s name or number in the header of every page, along with short copyright text. I use qpdf --stream-decompress to make the PDF into human-readable PostScript, and then Python+regex to remove each header text, which stand out a bit from other PDF elements. The script throws an error if more or fewer elements than pages have been removed but that hasn’t happened yet. Processed documents sometimes have screwed-up non-ASCII characters in the Table of Contents for some reason but I don’t have the originas anymore so IDK if it’s my fault. Still, I wouldn’t share the PDFs unless in text-only or printed form because of any other steganographic shenanigans in the file. I would absolutely torrent them if I could repurchase them under a new identity and verify that the files are identical.

    BTW, has anyone figured out how to embed Python code in PDF? The whitespace always gets reencoded as x-coordinates so copy&pasting it never preserves indentation. No, you can’t use the Ogham Space Mark (Unicode’s only non-blank character classified as a space) for indentation in Python, I tried.



  • Don’t be that pessimistic, most users had to install Reddit, Twitter and TikTok apps. In the 2010s, grassroots chain emails and Facebook posts with guides to setting up WhatsApp went viral among boomers in my country, touting it as “free SMS”. (Facebook camnot legally describe it as “free SMS” but they didn’t bother correcting anyone of course.) The fediverse experience is already quite OK if you have a dedicated client but the problem is that not everyone does, which is why we need browser support; people are tired of “wOrKs bEtTeR iN ThE aPp” even if it’s true this time. A dedicated URL scheme will automatically associate Fediverse links with any appropriate installed web/local apps. There are still other issues such as hit-and-miss cross-fedi-platform compatibility, no API for retrieving the list of federated instances and lack of appropriate error messages if the source and/or destination instance block each other.



  • Ironically, the thing that would allow people to use one “twitgramface” account across all the various platforms is federation. But the only way I can imagine it being seamless enough for normies is native browser integration for ActivityPub, perhaps with a new URL scheme like apub://.... Basically, save a Fediverse account in your browser, and when you open a foreign-instance link someone sends you, you’ll see a prompt:


    How do you want to open this link (apub:)?

    You can browse this content via your instance and interact with it with one of your saved Fediverse accounts, or choose an app you have installed:

    @yourusernamehere@lemmy.one    ︿
    @example@fedia.io
    @user123@mastodon.social
    Voyager (vger.app Web App)
    Tootle (Local App)

    ☐ Remember my choice for feddit.nl
    ☐ Remember my choice across all instances

    Accept Reject

    Why am I seeing this?    ︿

    This content is on feddit.nl, which is an ActivityPub instance that 3 of your saved Fediverse accounts federate with. To use your account, open this link via your instance, or select Decline to use feddit.nl’s default web interface.


    So far, only browser extensions can do this, and not very well at that. Of course, all ActivityPub instances and clients would need to adopt this URL scheme whenever a link is shared between users, and the downside is that Reddit, Instagram, Twitter etc. will never recognize apub: links. Do you think something like this can ever happen?




  • Yes but it’s wood that you are not allowed to burn or let rot, or the CO₂ gets released again. Basically, cut down trees and store them in oxygen-free water, salt mines, deserts or permafrost areas (or peat bogs, as nature did it over millions of years) where no bacteria/insects will feed on the wood and no humans come to scalp it. There is no way this can be economical, even with today’s carbon credits. Trees are “free” solar carbon capture devices but slow and inefficient, and need to be logged-and-stored continuously to work at all, as there is only a very limited space that we can cover in new forests in the next few decades.

    I know they just want to find the best use for waste wood but I think there is too little of it in the first place.







  • Yes. It’s not wrong 100% of the time, otherwise you could make a fortune by asking it for investment advice and then doing the opposite.

    What happened is like the current robot craze: they made the technology resemble humans, which drives attention and money. Specialized “robots” can indeed perform tedious tasks (CNC, pick-and-place machines) or work safely with heavier objects (construction equipment). Similarly, we can use AI to identify data forgery or fold proteins. If we try to make either human-like, they will appear to do a wide variety of tasks (which drives sales & investment) but not be great at any of them. You wouldn’t buy a humanoid robot just to reuse your existing shovel if excavators are cheaper. (Yes, I don’t think a humanoid robot with digging capabilities will ever be cheaper than a standard excavator).
