Show HN: Gomponents, HTML components in pure Go
Hey everyone! I just released v1.0.0 of gomponents last week. It's an HTML component builder in pure Go, with a DSL-like HTML syntax. It's been 4 years in the making, and makes it really easy to build HTML in your web apps.
Show HN: I made a site to quick identify any plant and learn how to care for it
I'm still working on it, curious but what feature may be most valuable for you? What do you think about personalised care instructions, and an interactive chat feature for each plant.

Show HN: Go Plan9 Memo
A quick dive into the Plan9 assembly I picked up while developing my SIMD package for Go, and how it led to a 450% performance boost in calculations.

Show HN: Clean News - A cleaner curation of world news events
Hello HN,<p>This a small side project I built a few months ago and I find myself using it quite often to stay up to date so I thought I should share.<p>Its updated every few hours.<p>Feedback welcome.<p><a href="https://cleannews.fyi" rel="nofollow">https://cleannews.fyi</a>
Show HN: Sava OS – A desktop interface for your web browser
Hello, I'm Owen, co-founder of Sava OS.<p>I think you've heard this a thousand times by now; "We spend most of our time on the web browser, yet nothing has changed." And then a "revolutionary" product comes out that puts our links & tabs collapsed on the side, with some extra features. Magical, right :)?<p>Well, we tried a lot of these products, and we also tried building one ourselves about 8years ago. But we felt like no UI can handle the same kind of organization our desktop can, and that's when the idea first came to our mind ~5years ago. For the past year, we worked on the side to build the MVP you see today. But along these years, a lot of thoughts kept popping up, and that's why this product has an OS in it's name (it's still cooking :).<p>Unlike other desktop-like products that are accessible on the browser, Sava OS is not only built and made to run natively on the web browser, but it actually has some useful features to help with your browsing management - and that's only the beginning.<p>There's still a lot to consider when it comes to shaping a modern, desktop-like UI that meets today's needs.. We’ve got some exciting ideas and aim to go beyond the traditional approach.<p>We would really love to hear your take on this.
Show HN: Automated smooth Nth order derivatives of noisy data
This little project came about because I kept running into the same problem: cleanly differentiating sensor data before doing analysis. There are a ton of ways to solve this problem, I've always personally been a fan of using kalman filters for the job as its easy to get the double whammy of resampling/upsampling to a fixed consistent rate and also smoothing/outlier rejection. I wrote a little numpy only bayesian filtering/smoothing library recently (<a href="https://github.com/hugohadfield/bayesfilter/">https://github.com/hugohadfield/bayesfilter/</a>) so this felt like a fun and very useful first thing to try it out on! If people find kalmangrad useful I would be more than happy to add a few more features etc. and I would be very grateful if people sent in any bugs they spot.. Thanks!

Show HN: A fair Product Hunt alternative
Over the past few weeks, I’ve been developing Simple Lister, a platform built to support indie product creators and give them a fair shot. If you’ve launched on Product Hunt recently, you might have noticed that only featured products get the spotlight, while others struggle for visibility.<p>Why Simple Lister?<p>Simple Lister aims to fix this by offering a more transparent and fair approach for product launches. Here’s how we do it:<p>• No favoritism: Every product gets an equal chance, and we don’t play favorites.<p>• Daily Underdog Feature: Each day, we highlight one underdog product to give them extra visibility and support.<p>• No hidden fees: There are no surprise costs. We have a simple submission fee, and that’s it—no pay-to-play or hidden charges.<p>Also we have a long to do list to do better.<p>Why does this matter?<p>After launching on Product Hunt ourselves, we realized how tough it is for smaller creators to get any attention unless they’re featured. Simple Lister is here to champion those indie products that deserve to be seen by a wider audience.<p>The platform is new and evolving, and I’m constantly working to make it better. If you’ve got feedback or questions, don’t hesitate to reach out!<p>Thanks for your support, and I’d be happy if you submit your products!

Show HN: Makedown – A Markdown powered Makefile alternative
`makedown` allows you to organise your shell scripts in one or several markdown
files, by mix and matching different scripting languages for various commands
and needs.<p>zsh/bash/sh, python, javascript or anything else available on your system.<p>Handy for replacing one-line-based package.json scripts or shell-based
Makefiles.<p>One can also write documentation and explanations to various commands in the same
`.md` file.<p>Most editors highlight correctly most languages in the markdown code blocks,
even when you use several scripting languages.<p>Here is a demo .md file <a href="https://github.com/tzador/makedown/blob/main/DEMO.md">https://github.com/tzador/makedown/blob/main/DEMO.md</a><p>More information available in the
<a href="https://github.com/tzador/makedown/blob/main/README.md">https://github.com/tzador/makedown/blob/main/README.md</a><p>Provided the following `example.md` in the root of your project,
the defined commands are available to run from any of the projects subfolders:<p><pre><code> --- Start of example.md ---
# hello
Prints "Hello" to `stdout` using Zsh.
```zsh
echo "Hello"
```
# world
Just prints "World" to `stdout` using JavaScript.
```js
console.log("World");
```
# weather-tomorrow
Prints the weather for tomorrow to `stdout` using Zsh.
```zsh
curl wttr.in/tomorrow
```
# generate-password
Prints a random password to `stdout` using Python.
```python
import random
import string
length = 16
characters = string.ascii_letters + string.digits + string.punctuation
password = ''.join(random.choice(characters) for _ in range(length))
print(password)
```
--- End of example.md ---
</code></pre>
You can run any of the commands from anywhere in the project,
just by typing `makedown a-command-name` or a shorter `m a-command-name`.<p><pre><code> $ makedown --help
hello - Prints "Hello" to `stdout` using Zsh.
world - Just prints "World" to `stdout` using JavaScript.
weather-tomorrow - Prints the weather for tomorrow to `stdout` using Zsh.
generate-password - Prints a random password to `stdout` using Python.
$ makedown hello
Hello
$ makedown world
World
$ m weather-tomorrow
Sunshine # prints more details actually
$ m generate-password
4444444444444444
$ m generate-password --help
Prints a random password to `stdout` using Python.
</code></pre>
The commands have simple syntax, they start with a header with a link and stop
when the next header starts.<p>Like so:<p><pre><code> # [a-command-name]() A short description.
Some documentation.
```bash
some command
```
</code></pre>
You can use other interpreters, like `python`, `node`, `ruby`, etc.<p>You can also use a custom interpreter specified using hashbang, like:<p><pre><code> # [run-deno-script]() Runs a script using the Deno interpreter.
Deno has to be installed on your system.
```typescript
#!/usr/bin/env deno run
const message: string = "hello, world";
console.log(message);
```
</code></pre>
All the .md files in the current directory and all the parents are examined
when looking for commands.<p>Would be very grateful for any suggestions or other feedback.<p>Thank you.
