The Stick of Jan Sloot (2004)

I have met him in person a lot of times: I worked at a local electronics shop and we used to bring him TVs and radios for repair regularly. He was socially awkward, stubborn, and on more then one occasion he made mistakes with regards to the repairs but did not want to admit fault at any time.<p>From my (rather limited) interactions with him, I&#x27;d say he was far from genius, I feel he just got sucked in and had no way out of his network of lies without losing face.

&quot;The Sloot Digital Coding System was an alleged data sharing technique that its inventor claimed could store a complete digital movie file in 8 kilobytes of data — violating Shannon&#x27;s source coding theorem by many orders of magnitude. The alleged technique was developed in 1995 by Romke Jan Bernhard Sloot (27 August 1945, Groningen – 11 July 1999,[1] Nieuwegein), a Dutch electronics engineer.[2] In 1999, just days before the conclusion of a contract to sell his invention, Sloot died suddenly of a heart attack. The source code was never recovered, and the technique and claim have never been reproduced or verified. &quot;<p>From wikipedia

Fascinating story though, possible or not. And there were some demos for investors, including iirc Sony Entertainment, which would have been hard to fake completely. So at worst, this guy was a decent magician..<p>There is a book on it with lots of details..<p><a href="https:&#x2F;&#x2F;www.goodreads.com&#x2F;book&#x2F;show&#x2F;3316995-de-broncode" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.goodreads.com&#x2F;book&#x2F;show&#x2F;3316995-de-broncode</a>

I once had an idea for a file transfer system based on digits of pi that sounds the same as this idea.<p>You&#x27;d give everybody DVDs of digits of pi (or they could calculate them themselves) , and then transfer files faster by just sending them the offset into pi.<p>At the time I thought it could work with a big enough bank of digits of PI on both sides. If transfer was expensive, and calculating digits was cheap then you could give everyone an infinite supply of digits of pi and have a nearly infinite compression system.<p>I discovered that often the offset into pi is much larger than the data you are sending. Turns out it&#x27;s an expensive way to sent things.<p>Also, it turns out that this area was already well understood. There are no free lunches with entropy.<p>But it was a fun idea to kick around.

A little OT: do the information theory based proofs of limits on how effective compression can be also prove that backwards time travel is impossible?<p>If backwards time travel were possible then your &quot;compression algorithm&quot; could simply be deleting the file. To recover the file go back in time to before it was deleted and make a copy.<p>With this you can &quot;compress&quot; giant files down to just a short description of a place and time where the file was on your computer.

Weird, I once read about Roel Pieper, completely randomly, in a trade magazine for Unix that I think had very few issues. He had just become head of Unix Systems Laboratories. I don&#x27;t know why that article stuck with me for so long. I didn&#x27;t know he was also a professor, I thought he was just an exec. Turns out he was professor of business, not computer science, though his original university education was in CS.

Hi I just see this via Twitter. My name is Tom and I have found JS SDCS inner works and OS in 2021&#x2F;22. I’m an ‘old school’ abstract artist and got through it by image research. Also my dad is a screenwriter so the tv was present in my upbringing. I have my personal story but it’s not about that. Under NDA I’m willing to share my sources and proof. Two people have validated my findings. One is too busy but has his own way by modern algorithms, one is taking it back to the past from step one. I need help and have a certain sense of urgency, btw I’m not afraid to be under attack. I cannot code, math, engineer or program properly. I do know how art, nature and stories of people work quite well. Thank you for your consideration and seriousness. I do need help to proof it with working samples. It’s one YouTube link away basically : ) and if you get it, it can be quite simple. Ty. Tom, Amsterdam, the Netherlands

&gt; The whole problem of Pieper&#x27;s way of thinking (and of every other person who believes that Sloot actually could compress movies with a factor of two million) is that he believes that the key does not need to contain every detail of a movie. Unfortunately, it does.<p>I wonder if one was scammed and bought a Blu-ray with everything, only to find out they got novels rather than movies. After the initial disappointment they might realize well written novels are better than movies and never watch another.<p>How about we get GPT to turn good movies into great books? Like a large inverse prompt engineering problem.<p>Could we then even feed that text as input to make a better, though arbitrarily different movie?

If the laws and initial state of the universe can be expressed in few enough bits, then all you need to store is a title and a date. Run a simulation of the universe, fast forward to the date the movie was released, use an AI to find a theater playing it, and digitize the tape. It may take longer to run than the current age of the universe, but eventually you’ll get it.

Offhand, this brings to mind the Vocoder. A reasonable facsimile of fluent speech could be be produced just from the bandwidth of a skilled typist operating a keyboard.<p>What&#x27;s encoded is not the audio - even the best audio codecs need on the order of 4kbits&#x2F;sec to encode legible speech - but the actual semantics on how voice is produced.<p>Suppose you want to do this for movies. 8 kilobytes doesn&#x27;t sound like enough, though the script of the movie could easily be compressed to that. But it&#x27;s posible to imagine a system into which all the skill of the cinematographer, director, script writer, actors, etc. are built, with from 8 kilobytes of instructions could create, perhaps not the original movie, but something comparable.<p>Is this doable? Does some random crank have the remotest chance of pulling this off with the technology of the day? No. But that&#x27;s likely the line of reasoning employed.

Inventors are a different animal. One doesn&#x27;t start with a reasonable theory but one works from the other end, one quite unreasonably starts with what would be wonderful to have. One doesn&#x27;t test a theory but one ponders how the seemingly impossible might be accomplished which is a problem that can be broken down into more reasonable things until it&#x27;s impossible component is defined properly so that one may make an often futile attempt to ask the question differently. With few exceptions there are no results. Those not skilled in the art consider that part cheating. This is logical because their line of reasoning seeks to further validate that what they already know, it thus involves an effort to prove something can&#x27;t be done, or at least not by someone like that, or at least not by that person, or at least not by that method etc etc<p>The cheating in this context would be to study the thing the file represents rather than the representation.<p>A dumb example would be to make a 10 hour movie from a single image that doesn&#x27;t move. There is no reason for the file to be larger than the original jpg.<p>&gt; I can not only get Orson Welles&#x27; Citizen Kane. I can get Citizen Kane in colour!<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=JI5qy9Zoh_0">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=JI5qy9Zoh_0</a><p>To argue that this was not the method Sloot used is missing the point. The question is: How to do it, not how to imitate someone else.<p>In his demo Sloot was playing 16 full movies simultaneously on a 1995 laptop at any speed. A high end computer had 32 MB memory, 133 MHz cpu, PCI video cards had 4 MB ram, 66 MHz, 560 MB HDD<p>If it was not what he said it was why didn&#x27;t he just sell what he had? Without the extraordinary claims the demo already requires cartoon physics. He drives the truck into the match box, making an U turn inside doesn&#x27;t at all seem necessary???

At least one of the ideas alluded to in this article is reminiscent of an actual audio &quot;compression&quot; algorithm. SAOL aka &quot;MPEG-4 Structured Audio&quot;<p><a href="https:&#x2F;&#x2F;sound.media.mit.edu&#x2F;resources&#x2F;mpeg4&#x2F;sa-tools.html" rel="nofollow noreferrer">https:&#x2F;&#x2F;sound.media.mit.edu&#x2F;resources&#x2F;mpeg4&#x2F;sa-tools.html</a><p>It was a growing idea in the mid-2000s but AFAIK it has gone absolutely nowhere. Essentially, instead of somehow encoding the audio, you encode a description of how to generate the audio.

Isn&#x27;t this trivially false, way before atoms, Turing machines, and any other drive-by namedrops I missed?<p>Given the notch = (A+B) &#x2F; 10<p>You can only recover A + B. You can&#x27;t recover A or B individually.

I remember the weird paranoia news that suddenly seemed to pop up everywhere only days after his death. People told me he was murdered by the big shot movie execs because of his amazing algorithms. It all seemed so strangely exciting. I wish i knew the &quot;exceptional claims need exceptional proof&quot; sentence back then.
