jclevy··on Prince of Persia in JavaScript
You are very welcome! I thank Jordan Mechner for creating this game and the Broderbund team for letting me be part of this extraordinary adventure...

You are very welcome! From time to time I meet people that played that PoP Atari version and each time it is heartwarming. Thanks.

Yes Paris is still a great place to develop video games (even if I'm not anymore in this field).

Here is a link to interesting and creative French game people and projects (it is in French, so here is a Google translated version: https://gamingcampus-fr.translate.goog/tomorrow-lab/gaming-i...)

Outside of Paris are also great teams like the Asobo teams in south west of France who developed Microsoft Flight Simulator 2020...

I'm really sorry, I did not work on "Stunts". I was also developing at that time a Formula 1 game, that was finally not released.

With Broderbund I worked on:

- Showoff (https://www.whatisthe2gs.apple2.org.za/show-off-/), a kind of PowerPoint software

- Downhill Challenge (port from Atari to Apple II GS - https://www.youtube.com/watch?v=6V5JZGHox7I)

- Prince of Persia (port from Apple II to Atari ST)

Um, that was really a long time ago...

As I can remember, my approach was the first one: "bottom up in literally translating instructions and assuming it will lead to same results if translated accurately enough". That was not to difficult to achieve.

The funny thing was that Jordan Mechner used every bit of available memory in the Apple II computer, so I had to be very careful ;-)

Then the hard part: create the input and output codes that were totally different on the two computers, then the code for sounds and music also totally specific and then I wanted to have better graphics. So I ended up by creating a sprite editor, in assembly language, for my graphic artist colleague so that we can recreate all graphic assets and put color in it...

Yes it is this one!
jclevy··on Prince of Persia in JavaScript
Yes of course it was released ;-) https://www.youtube.com/watch?v=aIscoVqTwpY And yes, I was working with Broderbund (from Paris) at that time, it was a great time! Translating 6502 Apple II code to Atari 1040ST 68000 code was funny...

Great job! It's amazing to be able to feel again the sensations I had 30 years ago while developing the Atari version of this game. Thanks again!
jclevy··on ChocoDB - will be a kind of nosql database running on SQLite
Yes, but usual relations could be implemented by default and generic relation still be available.

I just want to test this and see if the database can do more and my code less.

Being a child of, being included in...

You can of course manage all those relations in a relational database but the job is done by you, not by the database.

TouchDB is interesting but not immediately accessible for my node.js projects. And CouchDB is to heavy for my needs.

ChocoDB wants to (re)experiment new ways of dealing with database. It want to keep it simple and accessible.

jclevy··on ChocoDB - will be a kind of nosql database running on SQLite
You are right. On an iPhone, I will not use a SQL database.

Dealing with performance, ChocoDB is currently fast enough for me (2x times slower that classic SQLite ; my first version was 8x slower!)

jclevy··on ChocoDB - will be a kind of nosql database running on SQLite
Probably, but I haven't found yet my dreamed graph DB (serverless, Node.js compatible...).

I have to look deeper at SQLite4 spec...

I would say that my objective with ChocoDB is to make it accessible and useful to people who want to manage database structures and queries in a more natural way.

I want the database to help manage different types of relations: inclusion, group, structure, association...

Key/value is simple but it does not help to manage relations. Relational DB don't either help to manage different types of relations.

jclevy··on ChocoDB - will be a kind of nosql database running on SQLite
Yes ;-)

I think there is a need for light embedded schemaless databases.

jclevy··on ChocoDB - will be a kind of nosql database running on SQLite
Yes, it seems to close to want I want to do. I'll have a deeper look at goatfish.

No it's something I've had in mind for many year and that I wanted to build and test before being forced to used MongoDB or EJDB.

The source is in /server/reserve.coffee

jclevy··on Show HN: Chocolatejs with Chocodown (Markdown) Literate programming Lab
Is there someone interested?
jclevy··on Show HN: Chocolate.js, Live Web Ide and Framework
Yes, the Demo site has a self-signed SSL certificate.
jclevy··on Show HN: Chocolate.js, Live Web Ide and Framework
Thank you. Chocolate is the project name, but I had to add something at the end to create a web site and a visible github project. So js was the shortest and closest meaningfull suffix that came to my mind.
jclevy··on Show HN: Chocolate.js, Live Web Ide and Framework
I'm glad that you saw it! And it melts from time to time... ;-)
jclevy··on Show HN: Chocolate.js, Live Web Ide and Framework
But would my project Chocolate interest you if its source code was written directly in javascript?
jclevy··on Show HN: Chocolate.js, Live Web Ide and Framework
I understand. I'm sorry for that.
jclevy··on Show HN: Chocolate.js, Live Web Ide and Framework
It could probably be supported on Windows, but I'll need some help...
jclevy··on Show HN: Chocolate.js, Live Web Ide and Framework
I'll try to prepare a screecast in the following weeks. There is now a demo there: https://demo.chocolatejs.org/

There is now a non writable demo there : https://demo.chocolatejs.org/
jclevy··on Show HN: Chocolate.js, Live Web Ide and Framework
You are right. However Javascript is apparent and supported in the Ide and as I use Coffeescript an Javascript as a pair of programming languages, I called it Chocolate.js
