IT Hare on Soft.ware
If you're in trouble and cannot find an answer to a question which goes beyond Stack Overflow...
If you have a not-so-usual solution for your problems but need to justify it to your boss...
If you like to think on your own rather than blindly follow "common wisdom" and "profound truth"...
...then 'No Bugs' Hare on Soft.ware might be the right place for you.
Your mileage may vary. Batteries not included

Databases 101: ACID, MVCC vs Locks, Transaction Isolation Levels, and Concurrency

posted by

Quote: “for larger-scale MOGs, functionality-wise it is common to have 4 different types of databases: transactional processing (OLTP) DBs, real-time reporting DBs, archive DBs, and analytical DBs (OLAP)”
Another Quote: “both MVCC-based and Lock-based DBMS issue locks (and therefore, both can cause all kinds of trouble such as deadlocks etc.); however, the difference lies with the number of locks issued by them.”

Game Graphics 101: Rendering Pipeline & Shaders

posted by

Quote: “each of the stages of the rendering pipeline is operating on a large set of items (vertices or fragments/pixels)”
Another Quote: “These days, even if the program uses fixed-pipeline, that fixed-pipeline is simulated over shaders anyway 😉”

Game Graphics 101: Lights!.. Camera!.. Frustum?

posted by

Quote: “In games, more often than not, we’ll be dealing with so-called Phong reflection model.”
Another Quote: “with orthographic projection, the lines which project points from our 3D world onto our 2D screen, are no longer converging to one single point; instead, they go parallel to each other.”

Game Graphics 101: Textures, UV Mapping, and Texture Filtering

posted by

Quote: “Size-wise, textures are HUGE. Actually, in a typical 3D game, 90%+ of the space on disk (and of GPU bandwidth/RAM) are used by textures.”
Another Quote: “3D anti-aliasing algorithms can be divided into two large groups: ‘proper’ anti-aliasing (the one which tries to avoid anti-aliasing in the first place), and ‘post-processing’ anti-aliasing (the one which creates an aliased image – and then post-processes it to make it look better).”

MOG Graphics 101: 3D Maths Basics, Meshes, Client- and Server-Side Polygon Counts

posted by

Quote: “for the purposes of the MOG network communications, I usually suggest using Euler angles to represent rotations/orientations”
Another Quote: “One thing which persistently haunts 3D developers, is polygon count.”

Game Graphics 101: 2D Animation, Sprites, Double and Triple Buffering

posted by

Quote: “If you’re using double buffering AND perform buffer swap in sync with the V-Sync signal, your monitor will show your game just as a movie projector with shutter would show a cartoon in the cinema”
Another Quote: “I’ve seen a pretty minimal 2D engine written from scratch at a cost of 4-6 person-weeks”
