Re: starting with elias-gamma

I wrote this code in C some time ago: void write_classic_elias_gamma(int value) { int i = 1; while ((i <<= 1) <= value) write_bit(0); while (i >>= 1) write_bit(value & i); } Same algorithm, more user friendly listing: void write_classic_elias_gamma(int value) { int i = 2; while (i <= value) { wr...

Re: HELP WANTED: Magazine type-in page numbers!

There are 4 type-ins in it that are missing (the Hobby-Computer issue is not linked to any type-in so far): - Lander - Entenjagd - Dame - 3-D-Plot (utility) Ops, this magazine was duplicated by mistake! This is the correct link, including these type-ins: https://spectrumcomputing.co.uk/issue/10463/...

Re: HELP WANTED: Magazine type-in page numbers!

I forgot to mention that submitted fixes won't appear online immediately. They will be included in the following ZXDB update (about a week later). Therefore if you are willing to help, it's probably a good idea to mention it in this thread to avoid someone else doing exactly the same magazine. EDIT:...

Re: New Database Model ZXDB

I don't think these generated tables should be put together with the main data. Certain sites may have no use for them (for instance ZXInfo uses ElasticSearch instead of queries). Others may choose a different convention to display information such as publishers (in case of a title originally publis...

Re: starting with elias-gamma

ONCE zx0 is made on ZX it will save a lot of (reeeaaal) loading time from 13k to say 3-8 k IF i use a (real) loading scheme that is a turbo type then the 3-9k will act like 1.5 to 4k or even faster... These benefits (from using data that was compressed with ZX0) will be exactly the same, regardless...

In theory, the ZX0 compressor should work in a Z80 machine. However you probably won't be able to compress data blocks larger than 1K and, even so, it will probably take a VERY long time to run.

I don't think that's a good idea...

Re: starting with elias-gamma

Notice there's "classic" Elias gamma coding (that's explained in Wikipedia ) and the more efficient "interlaced" Elias gamma coding. There are also other variants such as Exponential-Golomb coding (see Wikipedia ). It's identical to Elias gamma coding except starting at 0 instead...
