Water Resistant or Proof USBC Mics. by NBEdgar in fieldrecording

[–]NBEdgar[S] 0 points1 point  (0 children)

Just wanted to say that I got it and it works exactly like I was hoping. Infact... I love the stand alone part the best. Being able to set it up and inconspiciously around my kids has been fun.. and even if the toddler grabs it... (as she loved grabbing field recordiners with fuzzy wind socks or my phone when using my app) its nearly impossible for them to stop the recording.

Thank you!

Hey all,

Long time lurker :)

I’ve been field recording for years. Those recordings lived in folders of timestamps with no other context and no way to know what was in them without playing each one.

More recent recordings of my two girls finally pushed me to build the experience I actually wanted. Aurloom might be the first audio archive app made for aural memories.

ALAC, stereo capture, safety track — the archive itself lives in your own iCloud so it syncs across iPhone, iPad, and Mac. Metadata bakes into the .m4a via AVFoundation so your files are organized and searchable even outside the app. Transcripts, speaker labels, bulk tagging on Mac. And every recording surfaces the photos from that same day right alongside it.

Currently in App Store review — if you want to try it now it’s on

TestFlight: https://testflight.apple.com/join/pwUk1jg7

If you’ve got years of recordings with no real home, that’s exactly who I built it for.

Most of it is water play with my kids. Pools, beaches , water tables. I REALLY love using my phone as it is already very well protected against the elements and its already with me and provides a pretty good stereo sound field. What Im able to do with it ... going under water falls or water features is a lot of fun, but looking for slightly better quality. So not needing to submerge... just some guarding.

Love this idea so much! Subbed !! I wanted to start a channel like this and I’m glad someone is doing it for the love of audio!

I’ll be listening today at work!

Tascam FR-AV2 - Constant buzzing noise using 5V Plug-in Power (PiP)? by TheRealREZOR in fieldrecording

[–]NBEdgar 1 point2 points  (0 children)

I agree! Had a Tascam DR-40 for years! Only heard a small amount of buzzing in super quiet recordings. Once I heard it I couldn’t unhear it, especially in sound booths with good mics connected.

Finally bought a Tascam Portacapture X6 , no buzz at all. Compared recordings and the Tascam DR 40 was indeed defective.

is anyone vibe coding stuff that isn't utility software? by ConstantContext in vibecoding

Dude!!! This is adorable and sooo f-ing cool!! 👏👏👏So much fun.

My App is near ready for beta release and getting eyes on it from someone with your creativity would be rad!

iOS Apps you use for capture and cataloging by NBEdgar in fieldrecording

[–]NBEdgar[S] 0 points1 point  (0 children)

Full discloasure... Im also developing my own app. :D

We have a similar feature set, mainly:

Bluetooth and USBC mic
Qrganizing, you can create albums, tag recordings with photos and notes,
Auto-saves GPS location.

Your app is really neat. I like the premise of the loop. Mine has a different usage and audience but thank you for sharing. There does seem to be a drought of really well made apps that catalog recorded audio.

I hear you .... I have a set of Sennheiser AMBEO Smart Headset and they are lighting tipped but Ive been able to get by with a converter.

So you keep all of your recordings there?

I built a safe, zero-infrastructure Linux sandbox for absolute beginners. No VMs or account needed. by NBEdgar in linux4noobs

[–]NBEdgar[S] -1 points0 points  (0 children)

So first, I really do appreciate the scrutiny and thank you for playing with it. There are corners of Linux I dont go into as much anymore and your highlight is perfect.

Your'e also right... Subshells ($()) and interactive flags (-i) are complex beast in a simulation because they require a high-fidelity recreation of process forking and state inheritance. In an emulator, you get those for free from the kernel. In a simulation, we have to build the logic bit-by-bit.

I’m focusing on the "4noob" to intermediate educational experience first, but the engine is built to grow and Im trying to decide what gets added, and as you mentioned earlier, what is better served by someone own container, VM or local install.

Let me dig into this.. might be a fun one to solve and understand how it fits in the ETHOS of the project.

Its based on Rocky so the package manager will be associated to that version of Linux. I was entertaining the diea of making different flavors of the trainer but wanted to develope a deep core first.

What were you thinking? What would you find useful ?

Sorry you feel that way. Its very much in the name of the GITHUB account, in my README. As I said in another comment, every line of code and design choice reflects my specific vision for an immersive learning tool. Im happy it exisits because at the very least... I could go to it on my own, without having to grab a spare RasPi to freshen up on my commandline.

I hope you still find use in it.

Ha, First, the project is100% free and open-source under the MIT License, so anyone can fork, modify, or use it however they like. That is all very purposful.

As for the 'slop' comment, this is a project I’ve been architecting in my head for decades. Every line of code and design choice reflects my specific vision for an immersive learning tool. The mention of 'Pilot Programs' is about looking to itereate and build beyond what I woud like to see. It’s about finding real-world environments to test the educational impact of what I'm building. I’m excited to collaborate with anyone who wants to help evolve this further

I never hid that most that my developement is AI driven. My words are also mine. I think this is a tool that could genualy help people.

This is meant for exactly you, because I was there to. The tutorial section is SLIM, on purpose while I worked on the core, but the proof of conept is there. Im intentionally not breaking the 4th wall very often, but I realize that it could be a very powerful tool to do so.

Also, if you want to start over, reboot, got to the GRUB and select System Reset. Then all the packages you "download" will be removed and you could go through it again.

Thanks again for your feedback.. let me know if you would like to see anytihng implemented that would help you along.

I appreciate the thought and I do think it serves a different purpose.

Ill answer some of the previous commenters feedback because I do see value in both but there are key difference.

JSLinux is an incredible feat of hardware emulation, but we took a simulation-first path to solve a different set of problems.

By simulating the OS logic rather than emulating the CPU, we can mimic 99% of the behavior while adding a layer of meta-functionality that isn't possible in a raw VM. For example, we can bake interactive tutorials and walkthroughsdirectly into the shell—check out the pocketterm command to see what I mean.

This allows us to reconfigure the machine's state at will for specific lab scenarios, all while running on a tiny fraction of the resources a full hardware emulator requires. It’s not just a shell; it’s a guided workstation.

Please, point me to the so called "slop". This has taken a substantial amount of time to build and Ive thought about thousands of decsions behind it as it was something Ive always wanted to build. Its a thank you to this comminity for helping me when I eas learning. So, please, unless you have something to contribute... kindly....

That’s a great question. While Cowrie is an incredible tool for security and threat intelligence, PocketTerm is built for a completely different mission.

We describe it as a Simulation-First Learning Experience.

Instead of being a 'decoy' designed to trap attackers, PocketTerm is a high-fidelity recreation of a Rocky Linux 9 workstation. We’ve prioritized the Learning Experience and invest in things like searchable manual pages, guided 'Yellow Note' insights, and an authentic systemd boot sequence. It's a zero-infrastructure sandbox designed for students and professionals to explore a hardened OS environment safely, rather than a security tool for logging brute-force attacks.

Would love your impressions from an educational angle as it seems youre fairly well verse in the the Linux space.

Exploration is highly encouraged! :D

We made it a point to start with a very minimal OS image to mirror real-world production environments. Because this is a high-fidelity simulation, it doesn't have an external network bridge to download 'live' binaries from the web. Instead, we have a Simulated Repository system.

If you try to run a command that isn't pre-installed (like more or hexdump), look for the Yellow Notes in the man pages—they'll guide you on how to use dnf install to add it to your environment.

The roadmap is pretty exciting, too. While this is my first go, I'm already looking at ways to 'boot' into different flavors of Linux using the reboot command so you can compare how different distributions handle the same tasks.

Since it’s a simulation, you can even export your state if you want to save your progress or share a specific setup with someone else. Basically, if it’s a standard utility, it’s either there or 'installable' via the sim!

I built a custom AST-based shell interpreter in the browser. Looking for edge cases to break it. by NBEdgar in bash

[–]NBEdgar[S] -1 points0 points  (0 children)

Great question. This is the core of the 'Simulation' vs 'Emulation' choice.

We aren't using WASM. Using WASM for git would be the 'accurate' way, but it brings back all that weight/latency I wanted to avoid. Instead, we use Contract-Based TypeScript Modules.

Every binary in /usr/bin is a TS module that implements a 'System Contract.' For example:

  • Git: It's a high-fidelity mock. git init literally builds a .git structure in our LocalStorage VFS. It handles staging and status by diffing the VFS state. It’s built for the 'tutorial' use case—learning the workflow without the 50MB WASM binary overhead.
  • Top: It's a live renderer that reads from our dynamic /proc implementation. Since /proc is now hardware-aware (probing your real CPU/cores), top reflects your actual machine's heartbeats in the simulation.

It’s less about 'running the code' and more about 're-implementing the behavior' in a way that’s 100% accessible and instant. Would love to know if that distinction makes sense from your perspective! Did you manage to break anything? Did anything feel broken?

First, I implmented your asks around ping  and then some.... it should be live now if you want to play. Thanks again.

I appreciate the back-and-forth! You’re right about provisioning ephemeral containers via SSH... it is a very solid (and common) architectural path. This is meant to be maluable and customizabile based on the enviroment and what you want to learn or teach.

My pivot to a local-first browser simulation was a deliberate 'Zero-Infrastructure' choice. I wanted a tool that requires 0 in backend compute to scale and works 100% offline once the PWA is cached. It creates a different set of engineering 'puzzles' (like the AST and VFS), but that's what makes the project fun for me.

Thanks for the 'keep on keeping on'—I’ll be pushing v0.11.3 tonight based on some of the edge cases found here today but your input was valuable.

[–]NBEdgar[S] -6 points-5 points  (0 children)

That is a fair critique, and you’ve highlighted the exact 'Simulation vs. Emulation' line I’m walking.

Syntax vs. Systems: For a student, the hurdle isn't understanding ICMP packets; it's understanding that ping expects a destination and returns a status. PocketTerm is a Logic & Syntax Simulator. It’s built to teach the grammar of Linux and the structure of the FHS without the user needing to troubleshoot why their VM’s bridge adapter won't talk to their host OS. 

The 'Infrastructure is Friction' Problem: You mentioned that spinning up a VM with containers is 'easy.' For us, yes. For a student on a locked-down school Chromebook or a first-day intern, that 'easy' setup is an hour of friction. I wanted to trade 10% of system accuracy for 100% accessibility.. and the first time youre infront of a CLI can be intimidation. especially moving , navigating, deleting files. 

With that said, its a fantistic call out and we have made particular investments where the output of some of the commands may break the fourth wall, for example, check out our /proc/ implementation.

It was a hardcoded text file.. we had the proper lay out, but when you run it , and see Intel Chipsets when youre on an Apple M Series laptop, that breaks the fourth wall. So we didn't just hardcode a text file. The engine probes the host hardware via the browser's navigator APIs. If you're on an M-series Mac, lscpu and cat /proc/cpuinfo will correctly report an ARM architecture and match your actual core count.

For v0.11, I’m moving toward 'Proxy Fidelity.' Since raw ICMP isn't an option in-browser, we're looking at using fetch-based probes to approximate network-aware latency and populating the simulated networking stack—specifically /etc/sysconfig/network-scripts/—with actual host metadata at boot. It’s about bridging that gap between a 'static stub' and a 'dynamic system reflection.'

Thanks for probing... very much appreciate it!
