- Tangente n°182, p34-35, "Les excès de la corrélation".
- Nous allons vers un changement épistémologique majeur. S'en remettre à ce type de calcul traduit un renoncement aux ambitions de la raison moderne, qui liait les phénomènes à leurs causes. Ces ambitions de la raison permettaient d'envisager la prévention, d'agir sur les causes pour changes les effets. Au lieu de cela, on se dirige vers un système de pures corrélations. [...] On ne cherche plus à comprendre l'environnement, on cherche à le prédire. Notre rapport au savoir change, mais aussi notre rapport au monde: on se focalise davantage qu'auparavant sur les risques. "Voir et comprendre" sont supplantés par détecter et prévenir". On passe d'une civilisation du signe, qui était porteur de sens, à une civilisation du signal, qui est une donnée qui ne signifie rien en soi..

Learn
- All participants spent most of their time studying examples, rather than reading the language documentation.
Web
- Delay non-critical task to idle thread, while forcing their execution if some user event depend on that task being executed first.
Network
- Every byte of a TLS connection explained and reproduced.
Game
- Detailed explanation on how to make a fast tile-based game engine. Tricks used:
- Use LEA instruction, most efficient to move bytes, but requiring modifying the stack pointer.
- Pre-process the tiles to cancel effect of fast rendering loop
- Reverse display order to cancel graphical corruption when interrupt occurs and load registers on the stack.
- Detailed explanation on 2D game optimization for a Super-Mario-like game. Various tricks are explained about fast scrolling, fast sprite handling...
- Background is generated by a LEA-field, basically a sequence of code generated by the game engine, and when executed, draw pixel to the screen buffer. The LEA-field is organized into sequence of code, each drawing a given scanline.
- Scrolling is obtained by a different offset in the scanline.
- When scrolling, the code in leftmost/rightmost columns of the LEA-field must be updated. This update is done by a code, which is also generated by the engine. This column-update code is generated to avoid duplicate register loading (typ. occurs when the scene has many duplicated pixels, like a blue sky).
- Sprite is also generated by a code, generated from sprite data.
- A very fast tile engine for the Apple IIGS, using advanced techniques to achieve 1 pixels every 1.25 cycles.
