Sincerely, at this point I think he should be banned. He brings zero contribute to the forum, and he clearly hasn't learned anything from any answer he received from other users. We are running in circles, and it seems to go on since ten years!

At this point, either he is trolling (and then he would deserve a ban), or he must have some real behavioural issues (and then there is nothing we can do to help him)

Sorry for the vent, but I think this joke has lasted too long

...You can't look for patterns in random data..

Albert, this is the answer. Believe it. Study maths to prove it. No more of this, thanks.

Albert has contributed to this forum in many ways, for a long time. For instance has made the fastest big number multiplier, he has made a parser, he has made games in opengl, he has extensively used win api and solved a few problems with his code with little help.

He never brags about his work.

He had a section for a while with trig art, which was well liked by many. He admits he is no great mathematician, so what.

There are a few supercilious specimens and bullies on this forum who**deserve** to be threatened a boot out, if only for the reason that they ~~walk~~ type amongst us.

If freebasic was a branch of the Institute of Mathematics, even then, I doubt if any of those stuffed shirts would advocate expulsion for somebody trying to prove a concept. in fact many of those that they ridiculed in the past came out tops in the end.

And remember our skier (British), Eddie the Eagle.

https://en.wikipedia.org/wiki/Eddie_the_Eagle

Ridiculed by all the alpine toffs. The same guy becomes a beacon for others, for his persistence and spirit if nothing else.

Albert reminds me of Eddie the Eagle, although he scores much higher at coding than Eddie did at skiing.

Don't ban anyone or block this topic please. Even if the current infinite compression folly is pointless, Albert over the years has contributed in many ways and we should all try to gently suggest other topics or problems to solve---who knows, with such an obsessive mind, if he can be guided appropriately there may well be some brilliant solution to some particular programming problem just waiting to be discovered. No point in getting worked up.

Indeed. This folly should be blocked, at this point. It's not good for anyone, especially for albert

@Dodicat

I've been playing around with "Altered Binary"

Where you use different numbers than the regular 1 , 2 , 4 , 8...

I've been fumbling around with Richards "Altered Binary" program he wrote for me...

But i need a better program...

Say if i start with a 3 , i need to find all the upper 7 bits and to adjust those bit positions , so the 8th bit is a small as possible..

If i start with a 3 , 4 , then ( 5 or 6 ) , i need a program to fill in the next upper bit positions...

Can you help??? I'd appreciate it...

=========================================================================================

!!~~ Back From The Ban~~!! .... It's funny that no one has posted to the "Squares" topic since i was banned...

The only people that post here to "Squares" are Dodicat , Richard and Albert.. and rarely sometimes another person..

I figured out another data compression , it's full-proof , but i won't post it...

But i want to share it with Dodicat.,

I told him if i get rich , I'd give him half the money , since I'm using his Zlib patch code for it...

All i can say is: If it's less than 8 bits then it makes it 8 bits , else if it equals 8 bits , then it makes it 7 or 6 bits.. so you can tell them apart...

The 1, 2, 4, 8, … sequence gives a minimum length possible binary representation.

Any number can be encoded uniquely by adding a sub-set of values.

If instead you tried to use 1, 3, 4, 8, … then how could you encode 2 or 6 ?

If you try 1, 1, 3, 6, 12, 24, … it will take more bits to encode the same number than 1, 2, 4, 8, 16, …

There will also be two possible representations of some numbers, example 4, by using the first 1 or the second 1.

You will find numbers difficult to compare as many will have two different valid representations.

Having duplicate representations is inefficient, so you might as well stick to the compact 1, 2, 4, 8, ...

Thanks for responding.. But i had directed the post to Dodicat..

Here's you "Altered Binary" code you wrote for me...

The problem I'm having : is if you only enter 3 bits positions.. It outputs a bunch of equates...

You have to enter in all 8 bits ... Guessing ..

Could you alter it , so the equate part , only uses the entered bits... Instead of requiring all 8 bits to be set..

Keep it simple.

You can play with the least significant 4 bits and recognise the patterns.

Your computer will be replaced before you have time to test the frequency of all 2^64 possible states.
