> On Aug. 3, 2022, one officer sent a memo to the acting police captain requesting the couple's home be marked as a "swatter house." The captain declined, saying it could cause a "complacency issue for responding officers.”

You'd think they'd be more concerned about constantly wasting time and resources to constantly send out SWAT to some random couple's house twice a week.

Ah, well that makes a bit more sense. Admittedly I haven’t really looked into Jev and thought it was an open decision model rather than a proprietary product from TypeSafe.

I’m looking at the LLM-generated SECURITY.md and this thing seems to pump a LOT of information back to some place called TypeSafe AI. That and the AI-generated comments from OP here make a few red flags go up for me.

Not just regular nitric acid either, but red/white fuming nitric acid in many cases!

Back during my teenage years I used to make the stuff for decapping projects and amateur rocketry by grabbing the ingredients from our local hardware store and distilling it in a make-your-own-moonshine kit I bought off of craigslist.

Worked great up until the police were called because the store employees thought I was making bombs. I hear heating up sulfuric acid is the better way to decap epoxy chips nowadays.

There are several “AI” deconvolution tools to remove stars which work exceptionally well: two of the most popular ones being StarNet and RC-Astro’s StarXTerminator. I’m willing to bet that the author used the latter for star removal as it’s become something of a standard in the astrophotography world.

I used Astra on one of my old observatories (an aging Explora-Dome) and I can say it's definitely a very nice experience compared to "legacy" tools like ACP from DC3. That being said, however, it kind of sits on the lower end of functionality compared to existing commercial observatory control offerings like Starkeeper's Voyager platform, especially when it comes to advanced scheduling features and scripting. Still, for basic needs it's nice to have a decent open source alternative in a very niche ecosystem.

I think GP was mostly referring to astrophotography when it comes to light-polluted areas. I live in a bortle 9 area (downtown) and unless I bring out my 20" dobsonian I'm mostly visually limited to double stars, planets, bright clusters, and extremely bright emission nebulae such as M42. With modern LED broad-spectrum lighting, skyglow definitely becomes a major issue, especially for broadband targets like Andromeda.

However, I've been able to capture stunning images (and an APOD) even in broadband within my city using dedicated astro cameras and modern gradient processing techniques quite easily, so we're definitely living in the golden age for EAA if you'd consider that as an alternative.

Funny I should see this on the front page, since I’m one of the (likely) few lunatics on HN who rents a pier at Starfront. So far I can say that they’re definitely one of the better offerings when it comes to remote observatories. Shipping my gear and setting it up was a tad painful, but once everything is operational the rest is a breeze. Plus the onsite staff are very responsive when it comes to servicing my CDK (cleaning/upgrades/resets/etc.)

For those who want to try telescope colocation on a budget, they also have a relatively cheap ZWO Seestar pier option. I haven’t given _that_ a try yet, but I’ve heard good things about it on Cloudynights.

Yes, it works, but there are some issues.

The first one being that the SoC configuration runs in DS-compatibility mode which does not expose all of the available RAM in the DSi, and nds-bootstrap won't properly redirect I/O requests to the external SD card, which means you either need to embed the rootfs in the NDS ROM which won't persist changes, or use a flash cart and run the DLDI build instead.

I very fondly remember this project when I was growing up too, and I credit it with sparking my interest in kernel development.

When trying to port some industrial control software to DSLinux, I ran into some bugs around how the SLOB allocator behaved under memory pressure. One of my patches landed upstream, even though SLOB is deprecated now. Still, as a kid starting out in the embedded space, it opened my eyes to the joys of hacking around with homebrew.

Fun fact: a modded DS still powers a large part of my local observatory's equipment.
