KingMachiavelli··on Show HN: Bigwords.page – Turn any screen into a sign. The URL is the app
Completely different architecture, but would be amazing if another device could control what message (or photo, embedded video) is displayed.

There's a huge industry around digital signage and I've always felt it could be replaced with a simple Chromium kiosk + auto-refreshed webpage content. There's really no need for expensive HDMI connections or custom video streams when we already have browsers.

KingMachiavelli··on Federal judge calls Flock 'indiscriminate mass surveillance'
That’s more like a therapeutic/occasional recreation dose and habitual users consume it multiple times a day.

A survey found that average daily consumption was 0.9g and median 0.35g.

92lb=41.73 kg = 41730g / 0.9g / 365 =127.032 average-user-years. Or basically a month’s supply for a small town.

Like most consumption, the top 10% easily account for >80% of total consumption.

KingMachiavelli··on Keys Not Included: recovering the signing keys for US driver's license barcodes
All of this is nearly pointless unless the photo itself is in the barcode and also signed. You only need a leak of a few hundred real IDs to cover all of the identifiable characteristics (hair, eye, skin color, approx height and weight). Leak a few hundred thousand a year and now you can’t even flag leaked IDs without some false positives.

A fake photo plus a valid barcode will pass any current check right? Unless you still do a secondary proprietary photo lookup that I don’t think exists.

KingMachiavelli··on AirPods 5
Super annoyed they did not announce a new AirPods Pro or Apple TV. My NVIDIA Shield is getting a bit old (not really an issue unless I want to stream raw 90GB Blu-ray).

A bit strange for Apple to let fairly popular products just go so long without a refresh. Just the vision component of the new AirPods could have been delayed, not really a critical feature anyway.

Apple Watch seems to be getting pretty good, might finally switch away from Garmin if the Apple one is as durable.

KingMachiavelli··on Show HN: Copperhead – Hardware as Fast as Software
Computationally what’s the difference between a human and an LLM besides scale and speed? Trained humans are still using heuristics and shortcuts. Just because these are subconscious and only possessed by talented, trained professionals doesn’t make the skill computationally special.
KingMachiavelli··on Apple reveals 'shocking evidence' from ex-employee's MacBook in OpenAI suit
Not sure why people are latching on to this. I'm 95% sure the AI agent was not "trained" on this intellectual property but rather the IP was just analyzed and it's usage and details were recorded to the AI agents memory (typically markdown/JSON summary of previous sessions).

The defense IMO is just trying to muddy the waters between "irreversible AI training that updates weights" and "AI learning by just storing secrets in text files".

Even in the 5% chance this AI model actually was fine-tuned or fully-trained (i.e the weights were updated), the employee did this while employed at Apple and used Apple IP as the training data. Even if the output is under fair-use (because it's transformative), (1) any IP created while employed during work duties almost always belongs to your employer and (2) the act of accessing Apple's IP would be (trade secret or regular) theft if done outside normal work duties.

KingMachiavelli··on Can Intel finally beat ARM on performance per Watt?
Hmm, I'm using the CachyOS kernel but on NixOS. What CPU/GPU are you using?

I tried using the flatpak Chromium in case it was some NixOS build optimization oddities but didn't see much of a difference.

KingMachiavelli··on Can Intel finally beat ARM on performance per Watt?
A more accurate title is can Intel (Linux/Windows) beat Apple?

If you don't want to run Windows, is there even a choice? My issue now with the non-Apple computers if you want to run Linux it's really hard to predict how awful Chromium/Firefox will be. My work Dell Laptop is only a 3 year old CPU with integrated GPU (and unused Nvidia GPU) but Chromium and Firefox are both slow as shit just loading pages like Slack and Outlook. Even resizing the browser windows seems 4-5x times slower than my M3 Macbook Air.

Maybe this is strictly a Linux issue but it hardly matters when the Windows ecosystem is pretty stagnant, full of junk-ware, and software development is much, much better on Linux/MacOS.

KingMachiavelli··on New cars are getting 1.2cm longer and 0.5cm taller each year
As much as I like to hate on larger cars. In reality, I use my SUV (3 row, Subaru Ascent) all the time for camping and outdoor activities (80% of weekends or so). I just took out the middle seats to build a full-size bed platform (75x45” or so).

My wife also drives a smaller Forester that we realize could have been an EV or hybrid. Although in CA, electricity is so expensive that it’s not much improvement over gas especially if you spend more on the car itself. Really, just a same model year but more fuel efficient sedan or one of those old 100-mile range EV cars is what you have to “downgrade” too.

Of course, it’s silly seeing all the oversized, sparkling clean massive trucks and SUVs on my commute while I’m driving my heavily scratched glorified minivan (since that’s what SUVs are now days).

KingMachiavelli··on FDA authorized Zyn nicotine pouches without knowing what they were made of
Don’t many medications and medical devices contain microplastics either on purpose (fillers) or un-avoidable (plasticizers in IV tubing). Unless the FDA has an existing microplastics policy, it would be weird to inconsistently apply it.

Lots of dental stuff like Invisalign or even regular braces involve keeping plastic and adhesives in the mouth for long periods of time. I think even some gum (non-nicotine or otherwise) contain plastics technically.

KingMachiavelli··on CarPlay Is Additive
In some states you no longer can interact with a phone at all unless mounted. Phone mounts kind of suck or you’ll be in a rental without your nice mount. A 15” screen is easier to read than a small phone bouncing on a mount.

If I’m spending $10K on something, I want the Android/iOS experience to be first-class instead of some shitty UI designed be people who I presume don’t drive cars.

Cars are otherwise fungible between brands. If one has CarPlay/Android Auto there is little reason to pick a brand that lacks support.

KingMachiavelli··on The French are painting their windows with chalk to beat the heat
Window units can be added to basically any existing home. And like you said roofs are an option. France could afford AC with their relatively cheap power but it’s just culturally and politically unpopular despite heat related deaths being extremely high and loss productivity it’s certainly more than the cost to retrofit.
KingMachiavelli··on I can haz smoller NixOS ISOs?
> build an image from scratch with the packages you want

Using what? Using NixOS to configure a system is orthogonal to the system actually running the Nix binary. Nix/Nixpkgs provide well maintained package derivations and module configuration for the largest amount of software of any ecosystem. IMO it's far simpler than Yocto or Buildroot or the dozen OCI container builder ecosystems that go in and out of favor.

KingMachiavelli··on California AB 2047 makes 3D printers off-limits to students, educators, business
Err, the email list has like 13+ bad addresses? I get a lot of "Address not found" responses.
KingMachiavelli··on Is it time for a new Embedded Linux build system?
Actually, quite an honest and in-depth review with many genuine good points about the state of Nix. If you genuinely need sub 1GB image sizes, you would have to reimplement many of the Nixpkgs conventions like glibc/systemd.

I’d still probably just implement this in Nix/Nixpkgs so I could leverage the rest of the ecosystem but that’s not trivial at all.

I wouldn’t even say Nix as a language is better than Starlark. The author is certainly well informed in the choices made.

KingMachiavelli··on Is it time for a new Embedded Linux build system?
My toolchain for both is managed by the Nix derivation wrappers. It’s trivial to set custom C/C++/Rust/Go/NodeJS flags. As long as I have one flexible build tool, I can customize it for both server and embedded.
KingMachiavelli··on Is it time for a new Embedded Linux build system?
IMO the nixos-rebuild scripts are unnecessary and just obscures what’s being built.

build-vm is the same as building the configs “config.system.build.vm” attribute.

nixos-rebuild is fine for getting started but you end up needing to use the attribute path to do anything more complicated like CI caching or inspecting the drvPath.

KingMachiavelli··on Is it time for a new Embedded Linux build system?
What do you mean by image? In Nix you instantiate a NixOS system and specify the architecture. There are a number of tools to build a disk image from a NixOS system.

$ my-arm-system = nixpkgs.lib.nixosSystem { system = "aarch64-linux"; modules = [ ./configuration.nix ]; };

$ :b arm-system.config.system.build.images.iso

KingMachiavelli··on Is it time for a new Embedded Linux build system?
Embedded just means ARM 99% of the time and it's cheaper and easier to use native ARM servers (AWS has them cheap) than to make 100% of software cross compile. Some parts of the firmware might need to be cross compiled but those projects are designed to cross compile.
KingMachiavelli··on Is it time for a new Embedded Linux build system?
I've been using Nix for "embedded" systems for few years now and it works fine. I don't quite understand why "embedded" has historically meant learning a completely separate tool. I've been building for x86 and ARM servers for 5+ years now, so why should targeting an ARM board be any different?

Like the article points out, the software stacks people use for embedded devices are the same as people use non-embedded use; Rust, Go, NodeJS, and sure still C++. The only real difference with embedded devices is non-OS components like the bootloader (u-boot, EDK2) and customizing the device tree. (And of course firmware flashing). Fundamentally those are all just packages that I can describe in Nix. I don't need a separate tool just because the board is small.

IMO the embedded space, especially in the US, is already pretty Niche. Most companies either just ship the vendors BSP example (Ubuntu/Debian/Yocto) and pay very little attention to the detail or re-useablity. Once you vendor declares the BSP EOL you are stuck unless you re-implement it yourself.

Using Nix (or Guix) has the massive advantage of a large and active community that isn't fractured like the Yoctoo/Buildroot community. (By fractured I mean there may by many, many people using those tools at $DAYJOB but due to vendor BSP customization they likely share much less with the upstream community maintained sources).

KingMachiavelli··on Did my old job only exist because of fraud?
Doesn't running consistent losses eventually cause tax issues with the IRS? If the losses are offsetting profit elsewhere, I would assume the IRS would become very interested in challenging the validity of the hobby business?
KingMachiavelli··on A record 242 US cities now have starter homes that cost $1M
Sure but homeowners can literally have their cake and eat it too. Homeowners who like where they live and don’t want to sell are best served by scarcity.

Unfortunately that means they can play both cards, they can benefit from scarcity while pretending to be anti-gentrification. And they can claim any pro-housing group is actually “pro scary capitalist developer”.

KingMachiavelli··on US Air Force B-52 bomber crashes after takeoff, Edwards Air Force Base says
Is there something systemic behind these frequent incidents with military aircraft? It is using old, legacy equipment? Is it due to using rushed, streamlined procedures designed for war-time even outside an active battle environment? Are there just many, many military flights daily so statistically one will be in the news every couple weeks?

IMO the danger to US service members outside of combat seems way too high. It's a well known fact most fatalities occur during training than during combat. (Sure this due to there being many more training exercises than active combat engagements but from a policy perspective it is very worrying).

KingMachiavelli··on FTX's former Anthropic stake would be worth about $75B at today's valuation
Assuming they would not have liquidated it earlier (perhaps via some semi-legal instrument) to cover past or future bad decisions. Crypto certainly isn’t doing well now.

The 7.84% state would probably be significantly diluted over this time frame so 4-5% is probably a more accurate estimate but perhaps high estimate.

KingMachiavelli··on GeoLibre 1.0
Wow quite nice. I’ve been working on a side project (so all vibecoding) a tool for canyon mapping (Canyoneering). I made a decent interface based on Leaflet and react but I struggled to add a more complex interface without just recreating the enormous QGIS GTK 2000s era UI. Look forward to consider adopting this stack and UI instead of rolling my own.
KingMachiavelli··on Ask HN: Why hasn't there been a real competitor to Ticketmaster yet?
I don’t get why Spotify didn’t inject themselves into the ticket buying pipeline. They recently announced something but it’s kind of strange.

I often find I learn about a festival or concert too late to buy tickets or they are prohibitively expensive. Spotify knows who I listen too and where I live, I don’t get why it can’t remind my to buy tickets X months before the event. I can even manually see an artists concert schedule.

It then be trivial to monetize this. If 50% of people buying tickets on Ticketmaster, actually are going through Spotify first, that gives Spotify a lot of power in an otherwise asymmetrical position.

KingMachiavelli··on Federal judge blocks H1B visa $100K fee
Isn’t it a self-fulfilling issue? Dependence on H1B and other visa dependent workers leads to lower salaries which discourages local talent from that specialty.

What requirements did the role have and what’s the salary range?

From what little I gather from online job listings, most foreign labor dependent positions are trying to pay 90K for a masters degree, maybe 120-140K Bay Area. Additionally, many of these job listings want extremely specific degrees or certifications that frankly are of little interest to US citizens - but F1 students will take any masters program despite the program having little salary benefit - the degree is a requirement for the visa.

I have a hard time believing you can’t find a US civil engineer who could learn the subject matter right out of college. Although saying that I know first hand low starting salaries have pushed students towards mechanical engineering or CS if inclined.

KingMachiavelli··on IPv6 zones in URLs are a mistake
IPv6 zones are great. IPv6 neighbor discover is great. Link local doesn’t need SLAAC or DHCPv6 server.

It seems clear that browsers would need to special case this and implement OS specific rules for what a valid Zone ID is.

Browsers have overloaded the URL/search/AI magic bar for years. I don’t quite see how IPv6 Zone ID are that different. They already auto append or auto hide the www subdomain.

KingMachiavelli··on I was recently diagnosed with anti-NMDA receptor encephalitis
Wow, it's crazy that some states have over 2x the mortality rate of others. Also pretty striking how quickly mortality increases with age even at "young" ages.
KingMachiavelli··on Green card seekers must leave U.S. to apply, Trump administration says
1. Born in typical midwest American town from American parents also born in the US just as their parents (at least 4 generations) 2. Nope, met after arrival. 3. Studies completed and employed legally. 4. "How soon after her last entry to the US did you get married" - actually maybe an issue, we just happened to travel internationally before deciding to get married sooner. But it would be silly to not return to the country you live and work in just because you took a vacation. 5. CBP doesn't even ask questions when you re-enter with valid visa documentation. 6. No previous marriages of either party. 7. No criminal history, not even a speeding ticket. 8. Nope, went to school, graduated, started working, so on.

We live together and spend >90% of our non-working time together so I can't imagine an interview being a problem.

As you can see, besides maybe the "crime" of taking an international vacation, our case is as simple as it should be.

> Also, anecdotally, USCIS seems to be taking advantage at interviews of people who don't have a lawyer by threatening the citizen to withdraw the case or by getting the citizen or immigrant to agree not facts that aren't in evidence or aren't true and then using those facts to deny or delay the case.

I mean that's really the issue. USCIS appears to be intentionally adversarial.
