No, I didn't misread, I literally don't need any computer program (maybe other than a hex editor) to decipher a JPEG image. I could walk you through each part of the image format and tell you how it impacts the output rendered. An interesting exercise to try is to give a JPEG to an LLM and ask you to walk through each byte ;-)

Nobody can say the same about LLMs, because nobody has managed to decipher them yet. This is an active area of research (Mechanistic Interpretability.)

Your post is conflating lossy discarding of information with extracting abstract concepts from information and encoding them into weights. This is why those weights do absolutely nothing until you run a prompt through them. On the other hand, obviously any media file can be decoded by itself without needing a prompt.

Those blocky compression artifacts you see are not hallucinations, they are the image viewer just filling in for missing details. You don't even need lossy compression for this; take a lossless image like a BMP and zoom in, you'll see those blocks again!

Interestingly, image viewers typically do this via interpolation of adjacent pixels, but a lot of hallucinations are actually the result of extrapolation, the opposite mechanism. Which is why LLMs can create output that was NEVER in any input data anywhere (hence the term "hallucination"!)

And if you think lossy compression is sufficient to avoid the "verbatim" requirement of copyright claims, you're welcome to explore the legality of selling transcoded versions of copyrighted content ;-)

I'm not sure what those links are in relation to?

    Windows

    Each story opens in a window holding its article above its discussion; drag the bar between them to share the room differently. A window can be moved by its title bar, resized from any edge, snapped to a half or a corner by dragging it there, maximised, or minimised to the bar at the foot of the page. Use Window > New reader window to open an empty reader, or a story row's Open in new reader window button to compare articles. Docked readers keep their articles when you select another story from the sidebar. Minimized readers can be restored and reused for their site. A window's Next story link reads on down the list in the same window.

    A link in a comment or an article to another Hacker News or Lobsters thread opens that thread in a window too. A link to a single HN comment opens the comment above its replies.

    While a story's window is in front, the Story and Discussion menus in the menu bar hold its commands: pinning, Next story, sorting, collapsing every thread, jumping to the first new comment. Each window also remembers where you were in its article and discussion, so a reload, or Back to a story that Next took you past, finds your place again. Closing a window forgets it.

    The whole arrangement lives in the address, so a bookmark or a shared link brings it back, and Back undoes the last change. Moving between Hacker News, Lobsters, their lists, Pinned and Find changes only the list, and leaves the windows open.

    The list

    The pin at the start of a row keeps the story in Pinned, and the cross at its end hides it. Pinned can be narrowed by words in the title, site or author, by source, and to the stories you haven't opened yet, and ordered by when you pinned them, by points or by comments; the filters are part of the address, so a filtered view can be bookmarked. Scroll past the end of the list to load more. Domain filters, in the View menu, hide every story from a site.

    Browsing view

    View > Windowed and View > Classic select the browsing view and save your default in this browser. Window view reuses a reader for each feed. Classic view opens stories and applets as pages. Open as a page and Open in a window are one-off actions that do not change your saved default. Direct page links always open as pages.

    Applets

    The Applets menu in the menu bar holds three tools, each a window of its own. Replies to me takes your Hacker News user name and lists the replies to your last thirty comments and stories, checking again every three minutes while it is open, and marking what is new since you last marked them read. Look up a user opens a profile on Hacker News or Lobsters, with their submissions and recent comments, as a commenter's name in any discussion does; the bar at the top of a profile looks up someone else in the same window, and Back returns to the one before. Who is hiring? filters the posts of HN's monthly hiring threads by the words you type.

    They read only what the sites publish to everyone, so none of them asks for a login, and your user name stays in this browser.

    Find

    Find takes any link and lists every time it was submitted to Hacker News and Lobsters, so you can read each discussion of it.

    About

    YAVCHN never sees your Hacker News or Lobsters login. The discussion is fetched from each site's public API; to vote or reply, follow the link above the discussion, or the arrow beside a comment, to the source's own site. Pins, hidden stories, filters and layout are kept in this browser only.
