Don't we need to shift existing and new open source projects to memory, CPU and GPU efficient code?

There was a time when operating systems and various programs required minimal resources (memory, storage, CPU) to run. I see a stark difference in the response of applications like VS Code that are built on Electron, versus IDE's like Zed that is built on Rust. I miss the nimble and fast response of Windows XP. The fast execution and response of games and programs built with C++. I know any language can be compiled to machine language and it'll automatically become fast, but the point I'm trying to make is that there was a time when engineers dedicated at least some effort to ensuring the resource efficiency of their programs. Today, that seems to be lost, with the focus shifting to quick delivery.

Programs written in C and C++ have their issues with memory safety, and I've heard that many Ubuntu modules are being re-written in Rust. That's one good choice. But when I see various other frameworks like React, Flutter, many Python frameworks (even when it's a wrapper around C++), or even just in time compilation, etc, and I see how slow and bulky they are, I realize that it not only creates a poor user experience of getting annoyed at the slowness of the program, it also consumes a lot more resources on the server, thus massively increasing the cost of running operations. Perhaps another optimization would be to have modules that automatically detect various types of GPU's and APU's and are able to not only shift a lot of the processing to the GPU, but also able to detect the GPU and recommend an appropriate driver if the user has not yet installed the right one (that can happen with users like me who did not know that AMD APU's needed a separate, specific ROCm driver).

It would be nice if the open source community considered slowly migrating to (and building) resource efficient code everywhere. I'm already doing that, by migrating my latest open source program from Python to C++.

Another important aspect to consider is syntax and semantics. Recently introduced languages have such weird syntax and nested code that it's mind-numbing to have to keep learning new syntax that was created based on the whims of some developer.

SQLShell – Desktop SQL tool for querying data files, and I use it daily at work. Looking for feedback.

I'm a data professional who lives in SQL. It's my primary tool for analysis, and I'd say I have a "black belt" in SQL at this point. I was frustrated by the friction of querying local data files (CSVs, Parquet, Excel) – either I'd spin up a database, write throwaway Python noscripts, or use tools that felt clunky for quick analytical work.

So I built SQLShell – a desktop SQL interface for querying data files directly. No database server needed. You load files, write SQL, get results. That's it.

# What makes it useful (at least for me):

DuckDB under the hood – fast analytical engine. I regularly query million-row files without waiting.
Load anything – CSV, Parquet, Excel, JSON, Delta Lake, SQLite. Drag-and-drop or file browser.
F5/F9 execution – F5 runs everything, F9 runs only the current statement. Perfect for iterative exploration (if you use SSMS, SQL Developer or similar tools, this feels familiar).
Ctrl+F search – instant filtering across all result columns
Context-aware autocomplete – knows your tables and columns
Right-click column profiling – quick stats, distributions, null counts

# What I'm looking for:

Feedback from other SQL-heavy users
Missing features that would make this useful to you
UX issues I might be blind to
General thoughts on the approach

Open source client alternative for Spotify ?

Hey everyone, I'm looking for an open-source client alternative for Spotify mobile. Basically an app that let's me login to my spotify account (bcs I have lot's of playlists) and let's me play the songs offline.

On PC I have Spicetify which has no ads, but I'm struggling to find a mobile alternative.

If you can recommend me some clients it would be perfect, thank you in advanced.

I use an iPhone but my daily driver is Linux. Apple's Universal Clipboard won't help me, so I built my own.

Copy on iPhone → Paste on Linux. That's it.

I got tired of emailing myself screenshots and texting links to my own number or having to manually use localsend for everything. Apple's Universal Clipboard only works with Macs, so I made Velocity Bridge.

How it works:

\- Runs a tiny local server on your Linux box

\- iOS Shortcuts send clipboard data over your home network

\- Text/images land directly in your Linux clipboard

\- No cloud, no account, no Apple tax

Pro tip: Set up Back Tap (Settings → Accessibility → Touch → Back Tap) to trigger the shortcut. Double-tap the back of your phone = instant paste on Linux. It's stupidly satisfying.

Install:

\- Fedora: `sudo dnf copr enable trex099/velocity-bridge && sudo dnf install velocity-bridge`

\- Arch: `yay -S velocity-bridge`

\- Any distro: One-liner curl noscript or AppImage

Comes with a GUI for easy setup, or run it headless as a systemd service.

GitHub: https://github.com/Trex099/Velocity-Bridge

Built this for myself, figured others might want it too. Feedback welcome!

Not good at understanding licences - Can I include flac.exe along with my compiled freeware?

Hello,

I have made a free Windows desktop utility that can use flac.exe (which I think is open source) (it may someday use a library but for now it's flac.exe ). I think it's approximately a decade old now.

I do not plan to make my own project open-source. On one hand I admire open-source, on the other hand I'm not comfortable sharing my source code/this code to the public. Though, it will remain free, not collect any user data or such. It does accept donations but I don't receive any for this particular project. I'm not even sure if it has actual users other than myself and I don't really care.

I have various understandings of open-source licences:

I think that sometimes you cannot include an open-source tool along with your project if you project itself it not open source (I think that FLAC falls into this category)
I think that sometimes you can include an open-source tool if the user is free to replace with another version of that tool, that might have been recompiled from the tool's original source code. (That would work for my project... but I think that's something I read about C++ Qt license and not FLAC.)

flac.exe is currently not include along with the project file, it's up to the user to point to their version of flac.exe .

Can someone who understands these better explain me if I could legally include flac.exe along with a freeware?

(Also, I do not want to share the project publicly.)

OpenQuestCapture - an open source, MIT licensed Meta Quest 3D Reconstruction pipeline

Hey all! I just released OpenQuestCapture, an MIT licensed Quest 3 app and pipeline for capturing spatial data from Meta Quest sensors for use for 3D reconstruction.

Why:

Meta recently launched Horizon Hyperscape, which produces impressive 3D reconstructions from Quest 3 sensor data. But all your data stays locked in their ecosystem. You don't control it, can't export it, and can't process it yourself. In fact, just 2 weeks ago they significantly reduced the quality of peoples' reconstructions without any notice.

I think that's the wrong approach. Spatial data should belong to the user.

What it does:

OpenQuestCapture captures Quest 3 depth maps, RGB images, and pose data to generate point clouds. While you're capturing, it shows you a live 3D point cloud visualization so you can see what areas (and from which angles) you've covered.

Then, the repo also has a helper noscript that converts that raw data into to COLMAP format for Gaussian Splatting or whatever 3D reconstruction pipeline you prefer. You can run everything locally.

Here's the GitHub repo: [https://github.com/samuelm2/OpenQuestCapture](https://github.com/samuelm2/OpenQuestCapture)

It's still pretty new and barebones, and the raw capture files are quite large. The quality isn't quite as good as HyperScape yet, but I'm hoping this might push them to be more open with Hyperscape data. At minimum, it's something the community can build on and improve.

There's still a lot to improve upon for the app. Here are some of the things that are top of mind for me:

* An intermediary step of the reconstruction post-process is a high quality, Matterport-like triangulated colored 3D mesh. That itself could be very valuable as an artifact for users. So maybe there could be more pipeline development around extracting and exporting that.
* Also, the visualization UX could be improved. I haven't found a UX that does an amazing job at showing you exactly what (and from what angles) you've captured. So if anyone has any ideas or wants to contribute, please feel free to submit a PR!
* The raw quest sensor data files are massive right now. So, I'm considering doing some more advanced Quest-side compression of the raw data. I'm probably going to add QOI compression to the raw RGB data at capture time, which should be able to losslessly compress the raw data by 50% or so.

If anyone wants to take on one of these (or any other cool idea!), would love to collaborate. And, if you decide to try it out, let me know if you have any questions or run into issues. Or file a Github issue. Always happy to hear feedback!

Built a tool to catch package.json/package-lock.json inconsistencies before npm ci fails

Hey everyone! I just published a new npm package that I've been working on, and I'd love to get some feedback from the community.

What it does:

The tool analyzes your package.json and package-lock.json files to detect inconsistencies before you run `npm ci`. If you've ever had `npm ci` fail because of mismatches between these files, this is designed to catch those issues early and explain exactly what's wrong.

Current features:

* Compares package.json and package-lock.json for inconsistencies
* Provides detailed warnings about what doesn't match
* Checks for Git installation in your project
* Verifies npm version compatibility with package-lock.json's version

Planned features:

* Automatic fixes for detected inconsistencies (suggestions/PRs welcome!)

Why I built this:

`npm ci` is great for reproducible builds, but the error messages when it fails aren't always clear about *why* your lock file doesn't match your package.json. I wanted something that could be run as a pre-CI check or git hook to catch these issues locally.

This also can be added to your CI/CD workflow, and prevent from deploying in case of an error.

Installation:

npm install npm-ci-guard

GitHub: [https://github.com/yaronpen/npm-ci-guard](https://github.com/yaronpen/npm-ci-guard)

I'm still early in development and would really appreciate any feedback, suggestions, or contributions. What features would make this more useful for your workflow?

Recommendation for privacy friendly open source software to create a (stolen) bike register?

Bike registers such as bikeindex (US) bikeregister (UK), bicycode (FR) or mybike (BE) prevent bike theft, increase chances of recovering stolen bikes and help to identify thieves. But they are not interoperable and custom solutions.

I wonder which open source privacy friendly solution could be used to create a similar 'open' register to be used by every country (or entrepreneur, bike theft insurance) which wants to use it. User would upload photo and denoscription (frame number, brand and model, colour etc., presumably in structured format), user could declare a bike 'stolen, and everybody (or just authorised users) could search/filter the list of stolen bikes by brand, frame number (fuzzy search) and then have an anonymous way to send a message to the owner of the stolen bike.

The solution should have a decent interface, not just a spreadsheet, and ideally not be easy to scrape/spam. And of course top protection of the private data.

Any sugggestions what would work best, and how much work would be needed to adapt it to the denoscription above?

Thanks a lot in advance for your help!
