[Summary] * eBPF: Technology enabling application developers to run programs within the kernel space, allowing them to utilize OS functions at runtime. * XDP: Technology based on eBPF that supports packet processing. * XDP consists of XDP driver hooks and the eBPF virtual machine, enabling secure packet processing in the kernel space with

[Summary] * Paxos is a consensus algorithm used in distributed systems, often seen as an extension of the two-phase commit protocol (2PC). * Spanner utilizes a leader-based Paxos with leases. * TrueTime in Spanner is a globally synchronized clock with bounded uncertainty, aiding in determining the order of events. * Through TrueTime, Spanner provides

[Summary] 1. On-demand Container Loading in AWS Lambda introduces how to reduce scalability and cold start latency by introducing Block-level loading, Deduplication, and tiered cache. 2. Block-level loading makes an image into a single file system through a flattening process, then divides it into chunks and uploads it to the

[Summary] 1. BM25 is widely used for ranking method for IR. But since 2016, ranking methods using Neural Networks have started to appear 2. Neural IR generally showed high MRR, but had expensive computation. Especially BERT, which showed excellent MRR, was too slow to be applied to services 3. ColBERT
