Could we run javascript on amiga

leGend, do you mean the website, or is it a coding question? There should be Amiga browsers with some version of Javascript interpreter? Whether built in or using an external one that you could use for your own needs.

I tested Coppershade with Javascript disabled just now, and it seems you can navigate the site to some extent but not the deeper articles. I'll have a look right away if I can fix it in a good way.

BTW, Ep. 45 "Scroll Commands" is out. Have a good weekend! :)

If you use a Javascript-less browser, or don't like to fold out the menu, you can now find and navigate all articles from the Articles page.

I love reading the coppershade articles. I would say it was a great inspiration while we did Neonsky, Negativ Prosess and Hexel demos. While working on Knarkzilla I was checking that site for understanding more about the cost of copper commands.

Cheers @rloaderro. :) I've now also cleaned up the Custom Chip Register Addresses page a bit and added corresponding include files.

And... also on Coppershade are all the sources for the demo in the Youtube tutorials, because now the demo is finished! \o/

Ep. 46 "Final! Crunch Time..." is now out. :) With a few Demoscene members mentioned WRT crunching... o/

Thanks for mentioning Shrinkler. :)

Just for the record: You say in the video that neither of the three mentioned crunchers have decrunch flicker. Shrinkler does provide that (the -f option).

Fun to see what a 30ish-year old commandline cruncher looks like. Back then, I only used crunchers with GUI (PowerPacker, Imploder, StoneCracker etc.).

Argh! Decrunch flicker just popped into my mind as a talking point, and I assumed so. Sorry about that. I'll add it to the video description for now. I might do a more in-depth episode on only crunching in the future, and then I'll have prepared notes of all the benefits and options. :)

Thanks for coverage of Cranker and reminding me of the issue with the executable bit.
I've recompiled the Amiga version with vbcc, which fixes the issue. It's is also faster than before. It's available on Aminet
and from my server http://neoscientists.org/~bifat/binarydistillery/cranker/

Two more notes: Although it doesn't communicate it properly, Cranker supports command line options in both the 'Amiga' and 'Unix' style at the same time, so these invocations are equivalent:
Code:# cranker infile outfile -m # cranker to outfile infile merge # cranker -m -f infile -o outfile

Regarding decrunch flicker: Cranker (really) loads and decrunches (and can do other things) at the same time. Try for example the options -d cinema for a progress bar, or -d progress for a text progress display.
If you are nostalgic about decrunch flicker, there's a line commented in in decranker.asm as a possible place for adding flicker. You can specify your own custom header using the -ed option. Five Finger Punch created decrankers which go as far as integrating parts of their demos into loading/decrunching.

A small update to solve the mismatch between how hardware should behave and how it did in #44 - a Race Condition between Copper and VBI which in the end was easy to imagine and fix.

Ep. 47 "Conundrum Solved!" is now out.
