Timep – A next-gen profiler and flamegraph-generator for bash code
Note: this is an update to [this](https://news.ycombinator.com/item?id=44568529) "Show HN" post. timep is a state-of-the-art [debug-]trap-based bash profiler that is efficient and extremely accurate. Unlike other profilers, timep records: 1. per-command wall-clock time 2. per-command CPU time, and 3. the hierarchy of parent function calls /subshells for each command the wall-clock + CPU time combination allows you to determine if a particular command is CPU-bound or IO-bound, and the hierarchical logging gives you a map of how the code actually executed. The standout…

In plain words
Timep is a profiler for bash scripts that measures per-command wall-clock time, CPU time, and tracks the hierarchy of function calls and subshells. It generates flamegraphs showing bash commands and their execution patterns, helping developers identify whether commands are CPU-bound or IO-bound. Designed for developers optimizing bash code performance, timep integrates by sourcing a single file and prepending "timep" to commands.

From the sources
`timep` is an efficient and accurate state-of-the-art trap-based profiler and flamegraph generator for bash code. `timep` does much more than "providing per-command execution times" -- it maps the full call-stack tree for the bash code being profiled, and (optionally) uses that call-stack tree to generate a FlameGraph of the profiled bash commands! - jkool702/timep
timep is an efficient and state-of-the-art trap-based time p rofiler for bash code. timep generates a per-command execution time profile for the bash code being profiled. As it generates this profile, timep logs command runtimes+metadata hierarchically based on both function and subshell nesting depth, mapping and recreating the complete full call-stack tree for the bash code being profiled. The timep v1.10 release is a smaller "quality of life" release that incorporates the following changes: timep v1.10.1 : added a guard for BASH_ENV and a new stress test See CHANGELOG.md for the changes introduced in previous timep updates. To use one of the older versions of timep, download its release…from github.com

CodeTracer – A time-traveling debugger implemented in Nim and Rust2025 · github.com · ▲334Hey! We are presenting CodeTracer - a user-friendly time-traveling debugger designed to support a wide range of programming languages: https://github.com/metacraft-labs/codetracer?tab=readme-ov-f... CodeTracer records the execution of a program into a sharable self-contained trace file. You can load the produced trace files in a GUI environment that allows you to move forward and backward through the execution and to examine the history of all memory locations. They say a picture is worth a thousand words — well, a video is even better! Watch the demo below to see…

Talanoa▲345Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!
