In the beginning of this article, we analyse one straightforward probabilistic calculation algorithm and highlight its shortcomings (Section 2). Then (Section 3), we describe the algorithm proposed by Robert Morris in 1978 and indicate its most essential properties and advantages. For most non-trivial formulas and statements, the text contains our proofs, the demanding reader can find them in the inserts. In the following three sections, we outline valuable extensions of the classic algorithm: you can learn what Morris's counters and exponential decay have in common, how to improve the accuracy by sacrificing the maximum value, and how to handle weighted events efficiently.

The usual debate is REST versus GraphQL, but are the two really that different after all? Let's look at the similarities and differences to understand which is best for your project.

A distributed ledger could prove helpful in other areas of the data economy, like manufacturing supply chains or airline partner ecosystems.

Our team at Storj is building a decentralized cloud object storage and when we decided to build it using Go, we thought we’d also utilize gRPC for peer-to-peer remote procedure calls in client/server interactions. gRPC is designed for environments like the one we are building at Storj. It connects services together with easy code generation,…

As more companies transform into service-centric, “always on” environments, they are implementing Site Reliability Engineering (SRE) principles like Service Level Objectives (SLOs). SLOs are an agreement on an acceptable level of availability and performance and are key to helping engineers properly balance risk and innovation. SLOs are typically defined around both latencies and error rates.…
