mtlsnk··on Show HN: Defcon and HN, the only two audiences I might find
After finding the AI version I assumed you had generated this as well. It's been a hot minute since I've done anything creatively with audio/music, but would have been interesting to work with AI generated or AI-assisted vocals like that. Off-topic-ish: I have the beginnings of a modular/eurorack synth boxed up after a move, still. Also very much a noob with modular, but I've been playing with the idea to hook up the cv to real-time network monitoring to give my network a voice. It would take some time/tuning to get somewhere musically, if it would evolve from pure noise at all, but I'll take a packet powered pseudo-RNG noise box. Putting the ARP in arpeggio.

Having only heard the final edit of course, but I'd say your voice works well for rap/nerdcore. As with all things: if you put in the effort/time you'll improve. You may find yourself not having to correct the flow as much. And if you're not looking to perform live, why would you care when you get the flow/outcome you like through slicing/editing?

The lyrics to me seem like you put too much thought into referencing tools/tech in every line, which makes me fail to stay with the story/subtext. The deeper meaning is lost on me. That may mean I'm not the intended audience, and therefore be an N=1 answer to the question you were floating here on HN.

Tool/tech ref to word/line ratio is lower for artists like Ohm-I, Dual Core, ytcracker, making it easier to follow the "plot". More palatable with a hook as well, but if that makes it too clubby/hip hop/not you then don't, obviously.

Thanks for sharing.

This is pretty sick, say more. It may not all make sense, but it flows and makes sense musically/rhythmically. The line "my system's uptime longer than your whole career" had me rolling.

What did you use to generate this? This version is miles better than the "OG version". If you don't want to disclose, I'll take more of where this came from.

Don't let your dreams be dreams; there is the Svalboard Datahand [0]. Though, you may need to sell a kidney to purchase it.

In fairness to the creator, it's a niche product that would have taken quite some time to develop.

I quite like BenVallack's video about the Svalboard [1] (and his videos in general about his journey through the world of split keyboards).

mtlsnk··on Ask HN: What are you working on? (July 2025)
I'm experimenting/prototyping 3D models to passively absorb specific low frequencies, with the idea of reducing fatigue/increasing productivity in the workplace (where making/taking calls is continuous). The 3D models are based off of a research paper by Yong Li and Badreddine M. Assouar, called "Acoustic metasurface-based perfect absorber with deep subwavelength thickness" [0].

Absorbing low (male voice; 80Hz - 300Hz, not including overtones) frequencies normally takes a fair bit of dampening material, unless something like a Helmholtz resonator [1] is used. The paper shows that a ~100x100x12mm 3D printed Helmholtz resonator may entirely absorb 125.8Hz (in an extremely narrow band). I'm uncertain about transmission losses (i.e. volume of the frequency perceived behind the material).

So far, I have created/vibe-coded a script to take the inputs: frequency and tile dimension (it's square). The output is a 3D object (.stl) which can be printed.

Today I tested my 3D model, which roughly resembles the model in the paper (1mm roof & floor as opposed to 0.2mm, because of printing difficulties), by using a DIY'D impedance tube and publicly available software [2]. The print was meant to be tuned at 125Hz, but results showed 131Hz and absorption factor of ~0.42 (lower number as opposed to 1.0 may be due to inexperience with all of this; it may be due to an imperfect test setup).

My impedance tube is made from 96mm (inner) diameter PVC tube, a Visaton KT 100 V 4 Ohms speaker, an amplifier, Motu M2 audio interface, 2 Behringer ECM8000 measurement mics and some 3D printed adapters (to hold the speaker and sample).

Nothing to concretely publicise or share so far, but am thoroughly enjoying the process of digging into a field (acoustics) completely new to me, solely out necessity and/or frustration in the workplace.

Should anyone be interested, I will share my project with HN once it has progressed to where I have something written up or worth sharing.

These subdomains/sites are most likely misconfigured in such a way that malicious actors are able to redirect to/host anything they wish.

There was a blogpost here on HN about this, showing that (Roblox/Robux) scams were also seemingly hosted on .gov sites. I can't find that post anymore.

Here is a publication related to what you've found: https://cofense.com/blog/threat-actors-exploit-government-we...

mtlsnk··on Show HN: Emdash – Slack/Zoom alternative for distributed team collaboration
I hadn't the time to look around further, so I missed the Google and Microsoft SSO login options. As long as those are/remain free, there is no SSO tax.

I will have another look when I have more time, thank you.

There are many small businesses that outsource their IT to managed service providers, but are understandably limited in their budget.

In my opinion, SSO tax results in arbitrary denial of employing best practices for these businesses.

Passwords are evil, because people generally don't care about security or don't have the capacity to employ proper hygiene around passwords. This likely means that SSO tax indirectly contributes to an increased number of account compromises (especially in small businesses, because more limited funds means more limited security; they're low-hanging fruit for bad actors).

This looks great. What is the reason for adding the https://sso.tax? Why did you make SSO an enterprise feature?

Is it due to some (technical) reason that would require a monetary compensation to be profitable?

SSO has security benefits (on top of the maintainability aspect) which would also benefit small businesses.
