Three Durability Modes, One WAL: Configurable Guarantees for Different Workloads

csharp dotnet database durability wal typhon

How Typhon lets a single transaction choose between volatile (~1-2µs), group-committed (~1-2µs amortized), or immediate-FUA (~15-85µs) durability — same WAL, same engine, per-commit override.

Deadlock-Free by Construction: How Typhon Eliminates Deadlocks Instead of Detecting Them

csharp dotnet concurrency database typhon

Why Typhon ships without a deadlock detector — three structural decisions that make lock-dependency cycles architecturally impossible, and why that bet was made before any code was written.

Microsecond Latency in a Managed Language: The Performance Philosophy Behind Typhon

csharp dotnet performance database typhon

Five design principles that let a C#/.NET database engine hit sub-microsecond transaction latency — from cache-line-aware structs to JIT-eliminated dead code.

What Game Engines Know About Data That Databases Forgot

csharp database ecs gamedev typhon

Game engines and databases solved the same problem independently. Typhon draws from both traditions to build a database engine purpose-built for game servers.

Why I'm Building a Database Engine in C#

csharp dotnet database performance typhon

Everyone says you need C, C++, or Rust for a high-performance database engine. I chose C# — here's why that's not as crazy as it sounds.

3D Programming

After a short break and holidays, let's resume the work on the renderer

New rendering features !

3D Programming

Adding normal mapping, tone mapping to the renderer.

Parallax mapping, more ambient occlusion and stuffs

3D Programming

Parallax mapping is done, improving occlusion mapping

More improvments…

3D Programming

Projector based texure, parallax mapping are added to the renderer

Weird things and improvments

3D Programming

weird things happening

Shadow mapping improvments

3D Programming

Improved shadow mapping

Perspective Shadow Mapping

3D Programming

Perspective Shadow mapping is a real pain…
I can’t get it work correctly, I’m putting the code on hold, and I’ll get back read more...

Craaaaaaaaash!

3D Programming

Lost three days into a partition crash!
Almost lost the 150gigs of data stored there, took more than a day to recover everything.

The beginning of shadow mapping

3D Programming

Adding basic shadow mapping

Ambient occlusion: done!

3D Programming

Adding precomputed, ray-based ambient occlusion

Updating the lighting

3D Programming

Improved deferred lighting

First shot of the renderer

3D Programming

First glimps after 2 days of work

SM3 Renderer

3D Programming

New hardware capabilities allows us to finally approach realtime 3d rendering with more realistic ambitions
