Show HN: Javaflame – Simple Flamegraph for your Java application https://ift.tt/Kw1kPQT

Show HN: Javaflame – Simple Flamegraph for your Java application Javaflame will generate a flamegraph of your application function calls, including the argument values and the return of each function. Check https://ift.tt/fCNxtkX to see an example. There are already some tools that render flamegraphs for java, but they are focused on measuring performance or require some other process running along with the application. They also record function calls, but do not record the arguments or return values from those functions. I needed instead something to help understand and debug my applications that was better than adding breakpoints and slowly step over every call. This is a simple java agent that renders a flamegraph on a html file, no extra dependencies or other processes involved. All you need is an extra argument passed to the JVM on the command line pointing to the java agent. It calls toString on every parameter and return value of every function that is included on the filter, so I wouldn't use this outside your dev machine. https://ift.tt/4Mewv0K November 8, 2023 at 04:39AM

Show HN: Cami.js – A No Build, Web Component Based Reactive Framework https://ift.tt/5Lt8izA

Show HN: Cami.js – A No Build, Web Component Based Reactive Framework Hi Everyone! My main motivation for making this was that I wanted something as powerful as Svelte or React but I wanted no build steps, no JSON API, and I wanted something as close to vanilla js as much as possible. I'm mainly a backend developer, and I wanted to simply return html with some interactive islands when I need to (whose components get 'hydrated' with by backend language's templates). Some key ideas: • It's centered around light dom web components • Uses a "reactive element", which uses observables for fine-grained reactivity • Rendering is done through lit-html's tagged templates • A pub/sub store • Easy immutability using immer (it powers the observable updates & also the reducers) It's my first 'serious' library that I'm using in some work prototypes, and it's also my first 'real' open source project, so comments & feedback would be great! https://ift.tt/JFY05oZ November 5, 2023 at 12:03AM

Show HN: EdgeDB Cloud and 4.0 with FTS and Auth https://ift.tt/fzrAk5Q

Show HN: EdgeDB Cloud and 4.0 with FTS and Auth Hi there! This is Yury, a co-founder. We've been busy for a while building EdgeDB Cloud and now it's finally here. EdgeDB Cloud is pretty cool and takes full advantage of our database. You get declarative schema, strict typing throughout, great performance, a query language that's best of GraphQL & SQL, and many many other perks. The Cloud itself is quite unique because of EdgeDB. Our query language gives you composability - so you can fetch everything for your page or API endpoint in one network request. And our protocol and client libraries give you auto recovery on network errors, automatic transaction retry, built-in transparent connection pooling, and many other benefits. Check out the blog post where we explain it all. And watch the currently ongoing YouTube Premiere of the launch! https://ift.tt/lyxG9q3 November 1, 2023 at 10:57PM
