TCP Medium

TCP conventional congestion control

TCP conventional congestion control treats packet loss as a signal of network overload, but this assumption breaks down on modern networks with shallow-buffered switches …

The serverless abstraction Medium

The serverless abstraction

The serverless abstraction hides servers so completely that many developers forget cold starts exist until latency spikes in production. What appears as pure function exe…

CPU Medium

CPU clock speeds

CPU clock speeds have been stuck near 3-4 GHz for nearly two decades, not because engineers gave up, but because physics intervened. The power density at higher frequenci…

AMD's Medium

AMD's 3D V-Cache

AMD's 3D V-Cache stacks memory vertically on top of CPU cores using through-silicon vias, turning a planar problem into a spatial one. It is the hardware equivalent of re…

SSD Medium

A modern SSD

A modern SSD's random read latency is now lower than DRAM access latency was in the year 2000. The storage hierarchy has quietly inverted in places: what was once hopeles…

Apple Medium

Apple M-series chips

The Apple M-series chips are not impressive because they are fast; they are impressive because they made the memory bus disappear. By putting DRAM on the same package as …

RISC-V Medium

RISC-V

RISC-V's entire instruction set manual fits in 236 pages, while x86 documentation spans thousands and requires a license to implement. It is the first major CPU architect…

chip Medium

brain-inspired nanoelectronic chip

A brain-inspired nanoelectronic chip demonstrated in 2026 could reduce AI energy consumption by roughly 70% compared to conventional GPUs. The breakthrough uses a modifie…

TCP Medium

The TCP congestion window

The TCP congestion window is a distributed rate limiter that uses packet loss as its only feedback signal. Every TCP connection on the internet is participating in a glob…

SSD Medium

modern SSD

A modern SSD's random read latency is now lower than DRAM access latency was in the year 2000. This means the storage hierarchy has partially inverted—what was once consi…
