Remember when personal websites had lists of selected links that you could use to navigate the web and find cool content? Let's bring this culture back! Here is my little contribution to that:

Programming

• Casey Muratori's blog. I specially recommend reading the Semantic Compression post.
• Handmade Hero episode guide, absolutely amazing series building a game from the ground up - made by Casey Muratori.
• Computer, Enhance! Another project from Casey Muratori, teaching all the nooks and crannies of low-level computing.
• Fabrice Bellard's website, the creator of FFMPEG, QEMU, as well as TinyCC and QuickJS - this guy is a legend.
• Glenn Fiedler old blog Gaffer On Games and his new blog Más Bandwidth - both provide very good resources for many game development topics. Glenn also has a cool channel where he talks about netcode, Network Next.
• Mr. 4th Lab, by Alan Webster.
• Hundred Rabbits.
• Inigo Quilez's blog.
• Ryan Fleury's blog.
• Andre Weissflog's blog.
• Andrew Kelley's blog, the creator of the Zig programming language.
• gingerBill's blog, the creator of the Odin programming language.
• Our Machinery archived blog.
• Molecular Matters blog.
• Wicked Engine's devblog.
• Randy's list, yet another list of cool resources for you to browse.
• Drew DeVault's blog.
• Fabian 'Ryg' Giesen's blog, a wizard from RAD tools and the demoscene days.
• Andreas Fredriksson's blog. Seems to be stale unfortunately, but has many posts packed with knowledge.
• Red Blob Games, from Amid Patel. I recommend the posts about terrain generation, really good stuff.
• Arseny Kapoulkine's blog, computer graphics and stuff.
• Bartosz Taudul's blog, creator of the Tracy frame profiler and other good tools.
• Ignacio Castaño's blog on texture compression, graphics and game development.
• Andreas Fredriksson's blog. This is a stale blog as far as I know, but there are interesting posts there.
• Bartoz Taudul's blog, the creator of the Tracy frame profiler.
