razerbeans··on US confirms for first time it has deployed space weapons
FTA it says the treaty covers "weapons of mass destruction". But historically (at least prior to the 2000's), there was an unspoken rule of not weaponizing space. I think that's changed in the last ~20 years and recall covered of China sending kinetic weapons into space.
razerbeans··on Show HN: Capsule – Single-file web apps that save their data into SQLite
I love this idea! One of the fallouts from widespread AI adoption that I've seen: They're very good at creating visual artifacts, but if you ever have to provide data in those artifacts, you don't really have a great way to share it without hard coding it.

> One downside with this approach is that multiple people working on it will create different copies. To make it possible to merge different copies of the same file, each data entry has a unique UUID and timestamp.

This was the first thing that popped up in my mind: Changes stemming from two sources and reconciling them. I see that you have a statement about how to handle data entry from different sources, but I don't see exactly how those are reconciled? For instance, if two users have a copy of the .capsule and make changes, then want to share their changes with the other, you have two individual .capsules with different data.

How do you merge them?

razerbeans··on Claude now creates interactive charts, diagrams and visualizations
Interesting. So if I'm reading this correctly, this is distinctly different than the artifacts that Claude creates? If that's the case, why create it inline as opposed to an artifact? Any time I get a visual, I tend to find them so useful that I _want_ them to be an artifact that I can export and share.
razerbeans··on Runtipi: Docker-based home server management
Anyone have any experience using this? I've been managing most of my homelab infrastructure with a combination of saltstack and docker compose files and I'm curious how this would stack up.
razerbeans··on Inner Speech
You know, I've never really thought about it. Yeah, I guess I do just remember the feeling and know that it's a step that I've completed. And when I recall the steps that need to be done, it's not really a cohesive spoken thought. It's like impulses of sensations? My brain is just like "Order's important. Red red, black black." without the words.

For really difficult mental tasks, I'll actually talk to myself or write things down so that they are less chaotic since the feelings/impulses in my brain may not line up. Kind of like a buffer filling up.

Now what really bothers my wife is when we talk about how we have conversations with others. I don't necessarily think about what I'm going to say verbatim when I'm talking to someone. It's impulses like I mention above where things kind of "flash" into my brain the moment before I say it. The best way that I can think of it is that it's similar to playing a sport where you have moments to change your trajectory and movement to accomplish what you want. I know thematically what I want to say, but I don't actually build the sentence in my brain.

Hope that helps!

razerbeans··on Inner Speech
I'll answer from my own experience (with no inner voice):

1) I have to be very explicit when reading with an inner voice (which goes to your second point). Generally, it is a kind of recognition that a word has a meaning and I "feel" that meaning, if that makes sense?

2) Yes. It feels unnatural though.

razerbeans··on Show HN: Beepberry – a portable e-paper computer for hackers
I'm a huge fan of Squarofumi. I've bought two Watchy kits and have absolutely loved coding all kinds of interesting things for them. Given that it's powered by ESP32, it makes development super easy.
razerbeans··on We’re About to See a Rare and Record-Setting May Heat Wave
Part of me wonders if it's similar to the "never carry an umbrella" dynamic? Maybe it's just a "well, this is just how it is, carry on"?

Anyway, it's probably different in our minds because in the southeast, the heat + the humidity can literally kill you. Not having AC isn't just an inconvenience there; it's an emergency.

razerbeans··on We’re About to See a Rare and Record-Setting May Heat Wave
I've had a very similar experience (both in terms of coming from the southeast and the "you don't need air conditioning here" lines). I don't know why people still say that AC isn't needed. Year over year, it seems to get worse. Add in the smoke from the fires that seems to settle in every other year, it just doesn't make sense _not_ to have AC.

A couple of summers ago, when the heat was so bad in the Seattle area, I called a local HVAC installation and repair company to talk about getting AC installed at my home (built sometime in the 80's). There was a wait list of _hundreds_ ahead of me and unit shortages. It was a nightmare. Luckily, folks seemed to reconsider installation over the winter and I was able to work our way up to the top of the line to get things installed during the winter. Best decision I've made.

razerbeans··on Proxmox Docker Containers Monster – 13000 containers on a single host
Trying to figure out what's unique here, but it seems like Proxmox is being used to create VMs that then run docker. Then docker on these VMs is used to spin up a bunch of containers. So really, it's just Proxmox -> VM -> Docker -> Containers. So it's dedicated docker VMs to coordinate containers...

I was expecting Proxmox's LXC capabilities to be used to scale up to 13000, but this is just VMs + docker allowing that. Seems like the same thing could be done with any LVM hypervisor and VMs? Can someone correct me if I'm missing something?

razerbeans··on A low latency guitar effects processor suitable for running on a Raspberry Pi
As others have mentioned, I think the interesting thing here would be understanding the latency for processing the signal. Anything in the single digit milliseconds would be fantastic! I know at one point I was looking into Raspberry Pi and ended up on Pedal Pi[0], though I couldn't get the parts I needed to make it work.

I ended up using Teensy[1] and related audio shields[2] to get things working from a sound/acceptable delay perspective. But being able to get things going on a Pi would probably make more of the advanced input controls much simpler to implement simply from a OS support perspective (like in this project with the WebUI). The UI I'm seeing in this project looks great and it would be cool to potentially see something like kits/preinstalled images roll out for this!

razerbeans··on Diodes Hate It – Clipping with DSPs
If you haven't taken the leap, go for it! That's actually how I started getting into effect pedals and now I'm hooked.
razerbeans··on Diodes Hate It – Clipping with DSPs
You've done a fantastic job of describing what I couldn't put my finger on! One of the issues I had when developing this code was what I referred to as a "jarring" noise when distortion gain was turned up. It's like you describe: almost "metallic." I alluded to the "jarring" sound in the article, and it's great to know the culprit! There weren't a lot of repos, articles, or forum posts that had examples of solid, straightforward distortion implementations, and now I can see why.

Hopefully, we'll see someone get some code out there that helps clean this up!

razerbeans··on Diodes Hate It – Clipping with DSPs
OP here! I'm admittedly new to the world of digital signal processing and don't have a math background. But what I _do_ have is a background in programming and guitar effect pedal building.

My hope with this site and series is to get people like me exposed to the possibilities a little bit of code and a Teensy can unlock for them. The lower the barrier of entry, the more cool things people can create. :)

That being said, I'd love to get feedback on good sources to learn more about signal processing/theory or any resources folks would suggest for covering the topic even better!

razerbeans··on Diodes Hate It – Clipping with DSPs
I appreciate your feedback and sharing your knowledge! I'll definitely be digging more into some of the things your mentioned to get a better understanding. The topic is a super deep one–though my goal (at least at this point) is to stay high level enough so that anyone could get started in making their own sounds/effects.

The lower the barrier of entry, the more cool things that people can come up with! I'm hoping that more without a math/EE/audio background like myself can get started and explore some more of these deeper topics :)

razerbeans··on Diodes Hate It – Clipping with DSPs
Interesting, I was under the impression that aliasing was something on the presentation layer (e.g. plotting on an oscilloscope). Have some breadcrumbs/links to share that would be a good resource on understanding aliasing in your context? Would be excited to learn more!
razerbeans··on Diodes Hate It – Clipping with DSPs
Hey there, no aliasing in this case. As for the clipping, this is effectively just hard clipping like you'd see from two alternating diodes in series on an analog gain circuit.

Admittedly, I'm early into moving from analog circuits to digital signal processing, so I could be off the mark on my answer. :) Hope it helps, though.

razerbeans··on Show HN: A Little Tool to Visualize Guitar Chords
This is exactly what I've been looking for, but unable to find in such an approachable format! I recently picked up guitar after almost a decade without, and I've realized that guitar tutorials online follow a similar structure as cooking recipes: full of fluff at the top and you have to scroll a while before you get to the content. Well done!
razerbeans··on LXC vs. Docker
Weird, I just tested on my proxmox instance and I was able to create a snapshot of a running container (PVE 7.1-10)
razerbeans··on Poll: Display points on comments?
I personally find that seeing the points by comments allows me to see interesting comments while I am skimming over a thread. I wouldn't mind having points hidden if there was some way that the most commented on threads or most popular threads appeared closer to the top of the story.

razerbeans··on Ask HN: Does reading HN ever make you feel like shit?
This is similar to the very same issues that I struggle with from time to time. I have found, however, that the best way to counter such feelings is to change your mindset. While easier said than done, changing your mindset to a more positive one will do wonders while allowing you to accept the fact that, while you won't be the very best, you are indeed capable of getting close. It boils down to putting on metaphorical 'blinders'. Don't worry so much about what others are doing, but worry about what you're doing. Get passionate about what you do or a project that you are working on. If your projects or ideas consume your mind there's no place for worry.

I've also found that talking to others about your ideas that may not totally understand the tech world and explaining to them in terms they'll understand will help in boosting morale. Often times, people will see with fresh eyes what others (such as those of us here) would overlook otherwise.

razerbeans··on Boardwalk: Port of _why's Park Place using Sinatra and MongoDB.
Sounds really interesting. Do you have a link to a repo by chance?
razerbeans··on Ask HN: What are you working on today?
Porting _why's park place to ruby 1.9/sinatra/mongodb.
razerbeans··on An apology...
Seeing the name-drop of the Apple engineer on Gizmodo made my jaw drop. I couldn't believe that they would do such a thing. This no doubt casts a shadow on his career and life. It's a reckless attempt by what appears to be a subpar site to make itself somewhat legitimate. In this respect, they've failed miserably.
