Since late 2011 I’ve been working on distributed computing platforms, where software that runs across more than one machine is running as what we’d call a cluster. Now, as I focus more on blockchain and DLT, a lot of the approaches to computing are similar. A lightweight version of the challenges with working on distributed… Continue reading Distributed computing is less binary, more probability
In 2010 I wrote a blog post called “Node.js, is this the next big thing?” I came to think about that again this week when I randomly watched Yevgeniy (Jim) Brikman’s video about the Play Framework at LinkedIn. Combine this with the progress of Scala.js and ClojureScript and I think we can conclude that node.js was very… Continue reading Rust, is this the next big thing?
Over the last few months I’ve been learning Clojure. Best way to learn I find is to use what you learn for something you find useful or interesting. This morning, while browsing Hacker News, I found myself reading about Vitter’s reservoir sampling algorithm, with an example developed in Ruby. After spending a little bit of time… Continue reading Playing with Clojure and sampling algos
A month back I blogged about wanting a better throughput scaling tools for DynamoDB. Not having been able to find an existing tool that ticked all my boxes, I ended up scratching my own itch and developed a small Java tool that runs in the background, monitoring a set of DynamoDB tables. The tool satisfy… Continue reading Building a better DynamoDB throughput scaling tool, part 2
For the TLDRs: This blog post presents the reasoning behing a project called ResourcePriorityBlockingQueue which is a blocking queue implementation that: Allows you to assign priority on tasks, just as with a PriorityBlockingQueue. Tasks may belong to task groups where each group may have a different priority. In that case, tasks are prioritized by group… Continue reading Resource aware queue
