Big-Endian vs Little-Endian: Byte Order Explained
Big-endian and little-endian are the two ways computers order the bytes of a multi-byte number in memory or in a file, and mixing them up produces wrong values.
Monorepo vs Polyrepo: Pros, Cons and Trade-offs
A monorepo keeps many projects in one version-controlled repository, while a polyrepo gives each project its own. Here are the trade-offs for change and builds.
How Containers Work
How containers work: Linux namespaces, cgroups, and layered filesystems explained — what Docker actually does and how containers differ from virtual machines.
Garbage Collection
Automatic memory management that reclaims memory no longer reachable by the program, eliminating manual deallocation and its associated bugs.
SQL Joins
Combining rows from multiple tables with INNER, LEFT, RIGHT, FULL, and CROSS joins, including NULL behavior and performance considerations.
Rust Ownership and Borrowing
The compile-time memory model that gives Rust memory safety without garbage collection: every value has one owner, and references borrow under strict rules.
SQL Indexes and Query Performance
How database indexes make lookups fast, when they help, and how to design them for predictable query cost.
Git Version Control
A distributed version control system that records the complete history of a project as content-addressed snapshots.
