What is Vibe Coding? # Vibe coding represents a paradigm shift in how we approach software development. Instead of meticulously crafting every line of code, developers describe their intent in natural language and let AI assistants generate the implementation. But this isn’t just about writing code faster—it’s about fundamentally changing how we think about, reason through, and validate our software.

NVMe, Modern I/O, and Scalable Databases: Building the Next-Generation KV Stores # TL;DR # The landscape of high-performance storage has shifted fundamentally. NVMe SSDs deliver microsecond latency and multi-GB/s throughput per device, shifting bottlenecks from disk mechanics to CPU, PCIe fabrics, and software stacks. For modern KV stores, this means rethinking metadata vs. data storage separation, embracing async APIs (io_uring), and leveraging kernel-bypass frameworks (DPDK/SPDK).

It’s a question that I’ve been asked a lot lately, and I think it’s worth looking into. Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety. It’s a language that’s been around for a while, but it’s only recently started to gain popularity. After all it has made it to 14 in the TIOBE index It is the most admired language in Stack Overflow Survery for 2024

Finally we have a really good package, project, dependency and environment management tool for Python. uv is a Python package, dependency and environment management tool. It is a good replacement for pip, pip-tools, pipx, poetry, pyenv, twine, virtualenv Coming from a rust ecosystem, uv is inspired by cargo and rustup. There are lots of similarities between cargo and uv. In the traditional Python ecosystem, there are too many tools to manage packages, dependencies and environments. uv tries to unify all these tools into one.
