GitHub - necdetsanli/EyeRest: A lightweight Windows tray application that helps you follow the 20–20–20 rule by reminding you every 20 minutes to rest your eyes and look into the distance.

Hi everyone,



I’d like to share a small open-source project I’ve been working on: EyeRest, a Windows tray application that helps you follow the 20–20–20 rule for eye health:



Every 20 minutes, look at something about 20 feet (\~6 meters) away for at least 20 seconds.



I spend a lot of time in front of a screen (coding, studying, etc.) and kept forgetting to take short eye breaks, so I built a tiny tool that quietly reminds me in the background.



What EyeRest does



\- Runs quietly in the system tray (notification area).

\- Shows a desktop notification when it’s time to rest your eyes:

\- Uses Windows 10/11 toast notifications when available,

\- Falls back to a classic tray balloon if toasts aren’t supported.

\- Uses a configurable interval (default is 20 minutes).

\- Optional left-click toggle on the tray icon:

\- Normal icon when reminders are active,

\- A “snoozed” icon when reminders are off.

\- Small Options dialog to:

\- Enable/disable reminders for the current session,

\- Adjust the reminder interval,

\- Enable or disable left-click toggling.

\- An About window with version and author information.



The goal is to keep it as minimal and unobtrusive as possible: no big UI, no background service — just a small tray app that gently nudges you to protect your eyes.



Tech details



\- Platform: Windows desktop

\- Stack: .NET Framework 4.8 + WinForms

\- App model: ApplicationContext + NotifyIcon (no main window)

\- Timer: System.Threading.Timer with marshaling back to the UI thread

\- Notifications: Microsoft.Toolkit.Uwp.Notifications for toasts, with a tray balloon fallback

\- Packaging:

\- MSI installer (Visual Studio Setup Project)

\- MSIX package published on the Microsoft Store



Repo: https://github.com/necdetsanli/EyeRest



License & privacy



\- License: MIT

\- No telemetry

\- No accounts, no cloud backend, no external services

\- All behavior is local to the user’s machine (tray icon, notifications, small dialogs)



I explicitly document this in the README and Store listing because I personally care a lot about privacy in small utilities like this.



How to contribute



If this sounds interesting and you’d like to contribute, I’d really appreciate it. Some ideas that are on the roadmap or open for discussion:



\- Smarter handling of user idle time (e.g. don’t nudge if the user is away)

\- Better persistence of options between sessions

\- More flexible snooze behavior or richer notification actions

\- Additional accessibility / UX improvements



You can:

\- Open an issue with ideas, bugs, or feedback

\- Suggest improvements to the code (refactoring, patterns, tests)

\- Help with docs, localization, or packaging (e.g. winget / Chocolatey)



Thanks for reading. If you have feedback on the project itself, or on how I’ve structured the repo (docs, packaging, etc.), I’m very open to suggestions. 🙂

GoSheet - A powerful terminal-based spreadsheet application built with Go

Hi r/opensource!

Over the past month, I’ve been building a CLI-based spreadsheet editor. I was inspired by sc-im—which I found powerful but unintuitive—and by classic 80s spreadsheet programs, which felt too limited for modern use, so I decided to build something of my own.

I chose Go because I’m actively learning it, and I enjoy its simplicity (it reminds me of C). I considered C/C++, but realistically I wouldn’t have reached this point until next year. I’m glad I went with Go.

In the early stages, I used tview because it provides great widgets (tables, textviews, buttons, etc.). But as sheets got larger, I ran into huge memory usage—over 1GB for a CLI app! To fix this, I restructured the internal design to use a viewport system and optimized the custom cell structure. Now only the visible cells are rendered, while the rest stay lightweight in memory.

I also built a formula engine, which worked surprisingly well in testing, and recently added workbook support so users can manage multiple sheets in one file.

I’d love for you to try it out and share your feedback. Suggestions, feature ideas, and bug reports are all welcome. Your thoughts will help guide the next steps for the project.

Best way to batch upscale videos Topaz level on Mac M3 Pro without overheating or throttling?

Hi all,

Ive a MacBook M3 Pro (18GB RAM) and want to bulk upscale short videos to Topaz Video AI quality. Running large batches locally on topaz causes serious thermal throttling and slows everything down. Are there any free or student-friendly cloud solutions, proxy workflows, python noscripts or automation pipelines or even open source upscalers that let me maintain 4k quality without overloading my Mac?

Thanks.

Wanting to Share my Three Open Source Projects!

# Benday: Workflow CLI for editing braille ASCII art

Ever wanted if you could speed up the editing of braille ASCII art? This might be for you. You edit a (semi-custom) image file on your preferred image editor, and it will reflect on the terminal. This is the most impressive of the three, so if you want to look at just one, look at the Github page of this fella.

Features

Preferred padding on the image (between braille characters) to reflect the terminal display (This is the reason why I did this in the first place)
Comment pixels (uncleanable without force-clean) for whatever placeholder purposes
Cleaning, padding toggles, and resizing operations
Export and import to and from braille ASCII texts

Check it out: https://github.com/noAbbreviation/benday

Releases: https://github.com/noAbbreviation/benday/releases

# Dihdah: Training drills for learning morse code

Pretty self-explanatory on what it does.

Features

Letter, word, and quote drills
Vim keybindings (Just not immediately apparent)

Check it out: https://github.com/noAbbreviation/dihdah

Releases: https://github.com/noAbbreviation/dihdah/releases

# Approxima: A command line program to loudly tell time (in chunks of 5 minutes)

Pretty self-explanatory too. Just made it portable and stuff.

Features

Portable, pipeable, can be silenced, alternative shorter format
Just does its stuff or something

Check it out: https://github.com/noAbbreviation/approxima

Releases: https://github.com/noAbbreviation/approxima/releases

Hoping these things are helpful to other people. Ciao!

How do i remove a large unwanted file from my git history?

Hello every one, I an issue in my repository where a PR that included a large binary file (it was a build output around 65MBs) was accidentally merged to the main repository, the problem is by then we weren't doing squash merges and now the file seems to be permanently writtend to our Git history and when a person tries to clone the repo, it downloads files worth 66mbs yes the actual useful code is in Kilobytes.

What is the easiest way to do this? does GitHub provide a tool to fix such an issue?

Even if you have a resource like a blog post that might help, PLEASE share it.

I’m building a Python-native frontend framework that runs in the browser (via WASM) - repo is now public

Hey everyone,

I’ve been building something pretty ambitious lately - a **Python-native frontend framework** that runs directly in the browser using WebAssembly (Pyodide).
It’s still early, still evolving, and **v1 isn’t ready yet**, but I just made the repository public for anyone curious.

**Repo:** [https://github.com/ParagGhatage/Evolve](https://github.com/ParagGhatage/Evolve)

# What works right now:

* fine-grained reactive signals (no virtual DOM)
* Python → WASM execution
* component system
* basic routing
* a simple CLI (`init`, `run`, `build`)

# Why I’m building this:

I wanted Python to feel like a *first-class frontend language* without relying on heavy JavaScript runtimes or hydration tricks.
Just pure Python in the browser + a tiny JS DOM kernel underneath.

# What’s next (towards v1):

* re-render engine improvements
* global store
* forms & events
* overall polish for the **v1 release soon**

If you're interested in Python, WebAssembly, browser runtimes, or frontend architecture, I’d love feedback.
It’s definitely not finished, but I’m building in public.



Happy to answer anything about the design, Pyodide, reactivity, or DOM architecture.

I made a small web-based 2D skeletal animation app from scratch in C

Hi everyone,
I’ve been working on a small 2D skeletal animation app written from scratch in C using raylib. It lets you build simple bone-based puppets, animate them frame-by-frame, preview the animation, and export it.

I used raylib for pretty much everything, and microui for the UI, along with a small custom window-compositing layer I built to handle the floating virtual windows.

Right now it doesn't support skin deformations nor frame interpolations, but that's on the queue, alongside many other features I’d love to add.

You can test the app yourself here: **https://puppetstudio.app**
And the repository is here: **https://github.com/SuckDuck/PuppetStudio**

Any contribution is welcome, especially example puppets, since I’m not much of an artist and would love to include better sample assets.
Any feedback would also be appreciated!

What apps that you wish were native to your OS not a electron based one

Title says it all. I want to know what apps you regularly use that are not native builds and are web technology wrapped in Electron.js.

Why am I asking this?

I see a trend that developers don't learn to build apps for the specific platform and in the end build bloated apps that take around 1 GB space in RAM even when Idle. So that is very annoying and I want to change that. I will try to quickly build those apps to help you out.

Lets discuss that

Criteria:
1- Should be open source
2- Don't have any third party dependency to paid api or anything like that

Using ClickHouse for Real-Time L7 DDoS & Bot Traffic Analytics with Tempesta FW

Most open-source L7 DDoS mitigation and bot-protection approaches rely on challenges (e.g., CAPTCHA or JavaScript proof-of-work) or static rules based on the User-Agent, Referer, or client geolocation. These techniques are increasingly ineffective, as they are easily bypassed by modern open-source impersonation libraries and paid cloud proxy networks.

We explore a different approach: classifying HTTP client requests in near real time using ClickHouse as the primary analytics backend.

We collect access logs directly from [Tempesta FW](https://github.com/tempesta-tech/tempesta), a high-performance open-source hybrid of an HTTP reverse proxy and a firewall. Tempesta FW implements zero-copy per-CPU log shipping into ClickHouse, so the dataset growth rate is limited only by ClickHouse bulk ingestion performance - which is very high.

[WebShield](https://github.com/tempesta-tech/webshield/), a small open-source Python daemon:

* periodically executes analytic queries to detect spikes in traffic (requests or bytes per second), response delays, surges in HTTP error codes, and other anomalies;

* upon detecting a spike, classifies the clients and validates the current model;

* if the model is validated, automatically blocks malicious clients by IP, TLS fingerprints, or HTTP fingerprints.

To simplify and accelerate classification — whether automatic or manual — we introduced a new TLS fingerprinting method.

WebShield is a small and simple daemon, yet it is effective against multi-thousand-IP botnets.

The [full article](https://tempesta-tech.com/blog/defending-against-l7-ddos-and-web-bots-with-tempesta-fw/) with configuration examples, ClickHouse schemas, and queries.
