Art of Roads in Games Skip to main content Art of Roads in Games January 29, 2026 7 min read Not sure if it’s just me, but I often get a primal satisfaction whenever I see intricate patterns emerging out of seemingly disordered environments. Think about the galleries of ant colonies, the absurdly perfect hexagons of honeycombs, or the veins on a leaf. No architect, no blueprint. Just simple rules stacking on each other that result in beautiful patterns. I can’t explain why, but seeing those structures always felt good. Humans do this too. And for me, one of the most fascinating patterns we’ve come up with is the roads. Sometimes I imagine aliens from faraway galaxies discovering Earth long after we’re gone. Forests reclaimed by nature, cities reduced to rubble, yet between them, a faintly pattern is still visible – the road network. I like to think they will feel the same way I do when looking at nature patterns. – “Man, someone really thought this through.” City Builders and Their Roads I’ve got to say, roads have fascinated me since I was a kid. I still remember playing SimCity 2000 for the first time when I was about five or six years old. I didn’t understand much. Definitely didn’t know what zoning, taxes, or demand were. But roads fascinated me from the start. I think roads lie at the heart of every city builder. It’s the fabric on which cities are built. Since that moment, I’ve played almost every modern-themed city builder out there. In the meantime, I’ve also started noticing them in the real world. Examining them in more detail. Roundabouts. Interchanges. Overpasses. Merge lanes. Noticing every intricacy. Despite every game bringing an improvement over the one before, something always felt… off. SimCity 4 added elevation and diagonal roads. SimCity 2013 introduced curved roads. Then came Cities: Skylines with a ton of freedom. You could know freeplace roads and merge them into intersections at any angle, build flyovers at different elevations to construct crazy, yet unrealistic, interchanges. I think this was the largest breakthrough. But something was still nagging me. Highway ramps were unrealistically sharp or wobbly, lanes that were supposed to be high-speed bent too sharply at certain points, and the corner radii of intersections looked strange. I mean look at this. This is probably what highway engineers have nightmares about. And then came the mods. Mods changed everything. The great community enabled a new kind of freedom. One could build almost anything: perfect merge lanes, realistic markings, and smooth transitions. It was a total game-changer. I am particularly proud of this 5-lane turbo roundabout: But even then, mods didn’t feel completely natural. They were still limited by the game’s original system. Cities: Skylines 2 pushed it even further, with lanes becoming even more realistic and markings as well. I think at this point, a non-trained eye won’t know the difference from reality.

CCC vs GCC – Harshanu February 8, 2026 CCC vs GCC Posted on February 8, 2026 • 15 minutes • 3024 words Introduction Anthropic recently published a blog post about building a C compiler entirely with Claude . They called it CCC (Claude’s C Compiler) and claimed it could compile the Linux kernel. 100% of the code was written by Claude Opus 4.6, a human only guided the process by writing test cases. That sounded interesting enough to test the claim and benchmark CCC against the industry standard GCC. The source code of CCC is available at claudes-c-compiler . It is written entirely in Rust, targeting x86-64, i686, AArch64 and RISC-V 64. The frontend, SSA-based IR, optimizer, code generator, peephole optimizers, assembler, linker and DWARF debug info generation are all implemented from scratch with zero compiler-specific dependencies. That is a lot of work for an AI to do. What is a Compiler, Assembler and Linker? Before we jump into the comparison, it helps to understand what happens when you compile a C program. There are four stages involved. Image credit: The four stages of the gcc compiler Preprocessor : Handles #include , #define and other directives. It takes the source code and produces expanded source code. Compiler : Takes the preprocessed source code and translates it into assembly language. This is where the real heavy lifting happens, understanding the C language, type checking, optimizations, register allocation and so on. Assembler : Converts the assembly language into machine code (object files). It has to know the exact instruction encoding for the target CPU architecture. Linker : Takes one or more object files and combines them into a single executable. It resolves references between files, sets up memory layout and produces the final binary. Why Compilers Are Beasts Writing a programming language is hard (prior vibe coding). Writing a compiler is on another level entirely. A programming language defines the rules. A compiler has to understand those rules, translate them into machine instructions, optimize the output for speed and size, handle edge cases across different CPU architectures and produce correct code every single time. GCC has been in development since 1987. That is close to 40 years of work by thousands of contributors. It supports dozens of architectures, hundreds of optimization passes and millions of edge cases that have been discovered and fixed over the decades. The optimization passes alone (register allocation, function inlining, loop unrolling, vectorization, dead code elimination, constant propagation) represent years of PhD-level research. This is one of the reasons why it’s ubiquitous. This is why CCC being able to compile real C code at all is noteworthy. But it also explains why the output quality is far from what GCC produces. Building a compiler that parses C correctly is one thing. Building one that produces fast and efficient machine code is a completely different challenge. Why the Compiler Is the “E

Introducing the Codex app | OpenAI Switch to ChatGPT (opens in a new window) Sora (opens in a new window) API Platform (opens in a new window) OpenAI February 2, 2026 Product Introducing the Codex app Expanding what developers can do, with the new Codex app for macOS. Download for macOS Loading… Share Today, we’re introducing the Codex app for macOS—a powerful new interface designed to effortlessly manage multiple agents at once, run work in parallel, and collaborate with agents over long-running tasks. We’re also excited to show more people what’s now possible with Codex ⁠ . For a limited time we’re including Codex with ChatGPT Free and Go, and we’re doubling the rate limits on Plus, Pro, Business, Enterprise, and Edu plans. Those higher limits apply everywhere you use Codex—in the app, from the CLI, in your IDE, and in the cloud. The Codex app changes how software gets built and who can build it—from pairing with a single coding agent on targeted edits to supervising coordinated teams of agents across the full lifecycle of designing, building, shipping, and maintaining software. The Codex app: A command center for agents Since we launched Codex in April 2025, the way developers work with agents has fundamentally changed. Models are now capable of handling complex, long-running tasks end to end and developers are now orchestrating multiple agents across projects: delegating work, running tasks in parallel, and trusting agents to take on substantial projects that can span hours, days, or weeks. The core challenge has shifted from what agents can do to how people can direct, supervise, and collaborate with them at scale—existing IDEs and terminal-based tools are not built to support this way of working. This new way of building coupled with new model capabilities demands a different kind of tool, which is why we are introducing the Codex desktop app, a command center for agents. Work with multiple agents in parallel The Codex app provides a focused space for multi-tasking with agents. Agents run in separate threads organized by projects, so you can seamlessly switch between tasks without losing context. The app lets you review the agent’s changes in the thread, comment on the diff, and even open it in your editor to make manual changes. It also includes built-in support for worktrees, so multiple agents can work on the same repo without conflicts. Each agent works on an isolated copy of your code, allowing you to explore different paths without needing to track how they impact your codebase. As an agent works, you can check out changes locally or let it continue making progress without touching your local git state. The app picks up your session history and configuration from the Codex CLI and IDE extension, so you can immediately start using it with your existing projects. Go beyond code generation with skills Codex is evolving from an agent that writes code into one that uses code to get work done on your computer. With skills ⁠ (opens in a new
