This is a serious challenge that grows more difficult as your cloud footprint expands.

A lot of things have come and gone in the last few decades in computing. This post will cover a short list of topics that I saw in my career that were either notable or that people used to argue about a lot. Or both. Some of this might be a fun trip down memory lane, and some may be PTSD-inducing, but it is important to periodically look back in computing to learn from past experiences, as things that seem inevitable outcomes today weren’t always so clear at the time.

Dynamic programming (DP), first introduced by Richard Bellman in the 1950s, is a fundamental algorithmic technique in computer science with broad applicability across numerous domains. In computational genomics, it has proven particularly effective for sequence-comparison tasks, including those involving DNA, RNA, and proteins. Over the past two decades, advancements in sequencing technologies have massively reduced costs and increased throughput, leading to rapid growth in genomic data.
