  • DAGs from Graph

    Still ChatGPT. But bad experience this time. I asked all possible distinct DAGs given an adjacency matrix of a graph (probably not connected). I insisted that the graph is not connected. But “it” pretended to just make a loop over the nodes and build “all possible dags” (it pretends). I must note that the solution […]

  • Exploring the Power of Windows in Rust: Unleashing the Potential of Sequential Data

    Just catch a glimpse from your windows (it was: “introduction”) The windows method in Rust’s standard library is a powerful tool for processing sequential data. It enables efficient iteration over fixed-size, overlapping windows of elements in a collection, offering a functional and concise approach to data manipulation. This article will discuss the usefulness of the […]

  • Streaming query result

    I know I will never write a post on this, really, not a complete post on this matter. But I am working on making service consume less memory, and for sure I will achieve that. By now this is just an idea of the result of the same request made by buffering a whole result […]

  • React Form, my wrong way

    Today I had to face form definition in react and I was afraid to some kind of repeatitive task.I looked for in in google, I found formik, react-redux-form, but I see it too complex, or too heavy. I am using reactstrap for frontend and maybe there is a premium library for form, but I am […]

  • My 2 days Journey on moving services to a swarm

    I work for, I wanted my company start to use tool for tracking project development in a centralized way, Jira was expensive as resource, and I can not ask such a step, so I asked a machine were to run Redmine. Then it cames the gogs, and, after little time, Jenkins. A number of […]

  • I stopped the data flow – on React best practices

    Reading the interesting article from Dan Abramov: I stopped at memoization. I did not know this technic before, but simply because nobody care so much about names before functional programming. And so I discovered how large is the cover of react hooks, useMemo() that does In a cleaner way with the hook, in my […]
