tldr; BPS is Broadcast Positioning System. Same principle as GPS: a known waveform is used to triangulate position and time. Advantage: indoor available, less easy to jam/spoof due to high tx power of broadcasting stations. BPS can be added to ATSC 3.0 Next Gen TV signal which is rolled out since 2019 in the US.

Current planning is public availability in 2027-2029.

A good gov presentation with an overview and technical details is here [1].

It is endlessly fascinating how deep the fractal patterns of interests go. I know of Arch of course but have never run across Arco.

From the post I can't tell it's actual reach or impact but it certainly seems to have been a significant piece of work in terms of scope.

I hope to still noodle on open source in my retirement (when it is time) but I could certainly see wanting to get out from under the many expectations.

It's extremely private. It doesn't have Google services by default, but makes it easy to install them as unprivileged apps that - apart from giving you more control over what they can do and limiting certain access by default - work mostly exactly the same way as their privileged installs on other versions of Android. It also lets you disable Internet access privileges to any app that you don't want to have phone home.

Beyond that, most of the other advantages will be less visible. They have hardened memory allocators that make various classes of security beaches significantly more difficult. There's a lot less superfluous background services eating resources. All that and more are listed on their website. It's well worth a read.

> adds systemd units (robots understand systemd; it’s how they’re going to replace us).

Indeed, is it kind of joke which is not joke from Fly.io perspective? Humans who have learned CS for 5 years and can create JIT compilers cannot understand systemd?

On the other hand, I'm still in a shock after realizing that you can't expect Frontend dev guy will be able to clearly explain which CORS headers and values they do need - they just keep saying "CORS not working, fix infrastructure!" and not learning MDN by heart.

Ironically there's no redundancy in NTSC. There are layers of information and they degrade downward until you have just a black and white picture with no sound.

In ATSC there is two types of forward error correction on the digital bitstream. The problem it faces is it sits in the same channel allocations as NTSC while having to deliver significantly more information than NTSC. That and the actual digital modulation used is not as ideal for receivers to capture.

You still often have one man with all the power in a parliamentary system. The Prime Minister. Take Canada as an example. JT had basically complete power over government. It's as rate for the prime minister party or coalition to go against him as it is for a president in the US to be impeached.

I think the trick has to be to just get better people into those positions. Which means better people need to have some incentive to get into politics. It's a tough one for sure.

This looks awesome and we're fans of the TUI aesthetic at terminal trove (1) (we're biased), it's also great that WebTUI has keyboard shortcuts to go with it.

Not CSS but similarly ratzilla (2) also comes to mind, that allows you to build terminal-themed web applications with Rust and WebAssembly.

Check out the examples (3) they look great!

In my opinion there's a "level 4.5" in between structured templating and full-blown procedural scripting: Using a general-purpose language to generate structured data, but then handing that over to a simpler system to materialise.

Pulumi is the best known example. Also, any time a normal programming language is used to generate something like an ARM template or any other kind of declarative deployment file.

This is the best-of-all-worlds in my opinion: Full capability, but with the safety of having an output that can be reviewed, committed to source control, diff-ed, etc...

Well I just have the reverse experience. My cargo bike is practical, has not been stolen yet and up to four children under 6 are fine to transport in it. I don't feel it especially unsafe.

I also use it for groceries. Sometimes using both the cargo bike and a bike trailer (on two different bikes). We don't buy nearly at many things though it seems. When I do use my car (doing groceries while the children are with the grandparents) I have to transfer them from the car to the bike anyway because I can rarely park close to my home.

My doctor (and my wife's doctor) is certainly easier to reach by foot than by car. And I guess I never have the kind of urgency that would require me to use a car in the city. If there's something urgent a bike is always faster in this city.

Truth is, Trump never said anything particularly intelligent or insightful. I think most commenters in this thread would make smarter decisions and would give better answers to tough questions without resorting to deflections and personal attacks . He always needs someone around to explain his boasting comments to make it seems logical, but this term, he’s not even surrounded by smart people anymore. It’s frightening.

This is a great idea. Like a 1905 person’s weird vision of the 1950s— getting a bunch of things wildly wrong, like fashion and geopolitics, but strangely accurately describing a fledgling attempt to mandate ‘seat belts’ and criminalize drunk driving, so as to diminish the tens of thousands of preventable traffic deaths yearly, against the lobbying efforts of industry and the insouciance (and even outright opposition) of the public.

This is how I use my Framework laptop around 80% of the time. So much so that I wish I could just detach the screen (and re-attach it easily).

I have the xreal air 1, and have the xreal one's on order, they seem to be the leader in this space with their on-glasses processing for "anchor" mode.

I got these primarily to start gaming, but really, I just use the one hour of downtime before bed to do side projects (usually coding) while laying down, and it's been great. And the spouse does not complain about the bright screen.

Another advantage is that the muscles around my elbows are a lot less sore, as a laptop really isn't ergonomic to stare down into, unless you build one with a much taller screen [1].

I want to like this — I think having ground-based alternatives to GPS and other space-based PNT systems is a very good thing! But after reading the paper at https://www.nab.org/bps/Broadcast_Positioning_System_Using_A... and other BPS information on the NAB's website, I think the NAB is being wildly optimistic about BPS:

• ATSC 3.0's physical layer can already transmit GPS time in a way that receivers could get it back out. What BPS brings to the table is a requirement and specification for accurately and consistently filling in the physical layer preamble fields containing the time data, along with a new physical layer pipe (think "low-level data stream") that contains additional information about the transmitter and, optionally, its neighboring transmitters.

• BPS is capable of producing time fixes when the receiver only has a lock on one source. This isn't surprising at all — GPS receivers can do the same thing. But either type of receiver with only one source would see a clock offset proportional to the path delay, which it wouldn't be able to compute and back out without knowing its position.

• BPS is only designed for 2-D position fixes. While that's a reasonable design decision (the vertical position error would be massive), it also makes BPS less useful for the NAB's "indoor positioning for first responders" use case, especially in areas with multi-story buildings.

• The need to receive and process/decode multiple, most likely non-adjacent 6 MHz channels for positioning increases receiver complexity and cost.

• The NAB claims that 1 kilometer of separation between two BPS transmitters is "sufficient for useful position determination." I don't buy it, especially in the face of poor transmitter geometry.

• They note that 16 TV stations in the New York City area broadcast from One World Trade Center, so for the purposes of BPS, they're effectively one station. This kind of transmitter colocation is incredibly common, both in urban areas (ten TV stations broadcast from Sutro Tower in San Francisco) and in more rural areas (six TV stations in the Roanoke-Lynchburg DMA broadcast from towers within ~1 mile of each other on the ridgeline of Poor Mountain). Even if every ATSC TV station became an ATSC 3.0 w/ BPS transmitter, bad transmitter geometries would destroy BPS's position accuracy in lots of markets.

• What's the business case for broadcasters? BPS won't be free for broadcasters to implement, and there doesn't seem to be a path to it generating revenue except for a hand-wavy "maybe one day televisions will be able to determine their locations without Internet connections using BPS, and then broadcasters can do location-targeted advertising with those TVs!"

My uncharitable take is that BPS will never be a usable standalone PNT system. A timing system in the "rebroadcasts GPS" sense? Maybe. Standalone positioning? No way. Broadcasters implementing BPS (or ATSC 3.0 at all) without being forced to by the government? I don't see it.
Ask HN: Is the US losing to China in tech creation and production?
by bicepjai | 2025-04-13 06:11:38+00:00
(Post created working with Gemini 2.5 Pro) In the latest tech news for 2025, I'm noticing concerning trends:

AI Models: Chinese companies like DeepSeek are gaining significant momentum in the open-source AI space[5]. Their models are becoming competitive with US offerings from OpenAI and Anthropic. Recent benchmarks show Chinese models performing exceptionally well in reasoning tasks[3][5].

Smartphones: The OPPO Find N5 released in February 2025 outperforms the iPhone 15 Pro Max in several key specs: larger 8.1" display vs 6.7", 16GB RAM vs 8GB, 5600mAh battery vs 4422mAh, and faster charging (80W)[2][4]. The OPPO Find X7 Ultra's camera system also ranks higher on DXOMark than the iPhone 15 Pro Max[6].

AR/VR: Chinese manufacturers are producing more affordable and feature-rich AR/VR glasses than US counterparts.

Is this just market competition, or are we witnessing a fundamental shift in tech leadership? What structural advantages does China have in tech creation and production that we should be learning from ?

As others mention, a reverse "class action" isn't a thing.

I see it a bit differently:

A solid, high value contract should make sense. And guess what? When they do make sense, most people have no reason not to pay and they will, barring emergencies and the usual risks that play out in all business. Most people, myself included, would side with Adobe. The peeps need to pay up.

However, when the contract is shady, abusive, just dripping with greed? A much higher percentage of people are gonna say, "fuck 'em! Plenty will find reasons too. And there is a higher inherent risk associated with all new accounts, potentially going as far as to raise it, while value dilution happens across the board to software subscriptions as a whole.

Who wants all that noise?

I am not sure whether the piece mentioned this or not (skimmed, Ok? LOL), but there are fairly strong second and third order effects playing out that are likely to persist for a very long time:

Network effects: A pretty healthy slice of Adobe users, or forced users I could say, reach their hating peak every year. When I was skill building for creative work, Adobe hate was modest. Adobe love was higher than average too. So far, so good, right?

Just half a decade later, I revisit this work about the time people could no longer buy the suite on physical media with a perpetual license. Hmmm... haters were right! That is exactly what they said Adobe was going to do. Some time after this change, and while watching how Adobe handles the users of one of their more hated acquisitions; namely, Alias and MAYA who came from industry culture that believes Autodesk could quite possibly be one of the worst to end up owning what many observers called "elite" or "career" type software packages with costs starting in the mid to high 4 figures and ending up a solid 5 figure purchase ... (Alias 10 forever hoo rah!) ... um, yeah, where was I?

Yes, Hating Adobe solid now. Not ever going to be a potential customer.

You are reading third order effects. People like me, and the very aggressive first order people are hard at work figuring out just how much they can do with alternatives and also realizing everything they can do with the OSS alternatives are publishing our work, sharing successes and when we are teachers, consultants, department heads, we de-recommend Adobe on sight, while at the same time being very forgiving as people ramp up on the other options.

That catches the attention of many who would never have a clue if it were not for social media bringing us the very best drama like this.

Takes years and real talent to grow a software business while also so damn consistently earning the hate. Amazing!

> Regulations require a bureaucracy in order to be effective.

That's a very European point of view (though not uniquely European, it's also shared across many other cultures, e.g. in East Asia). The US has done pretty well with private rights of action. In fact, because our culture is so conservative and anti-authoritarian, centralized bureaucracies are rather quickly defanged or grossly underfunded. The most recent example is the Consumer Financial Protection Bureau, and more quietly the FTC. Democrats would have done much better to roll back judicial expansion of the Federal Arbitration Act and devolve "regulation" back to states and private class actions, rather than to create the CFPB and elsewhere double-down on anemic, extremely inconsistent, and often highly partisan agency regulators.

Where private rights of action tend to fail is when they concern inchoate or non-individualized harms, like you often see in environmental protection law. Then what you get is complete paralysis, such as with real estate development; largely because its the process, not the end-state determination of rights, that private actors weaponize. But when they're firmly anchored to property rights, personal injury or loss (including fraud), etc, they seem to do as well as centralized regulation. And in the US, they arguably do better, because of our political dynamics.

there was a scene in SG-1 where O'Neill locks up a bunch of aliens in a room and said they would not be released until they came to some agreement.

I always thought there should be a religious army with the entire world's military might, who's central tenet is that they do and decide nothing except enforce what the nations decide - and the nations get to decide in any way they want except violence - but they may choose a champion on each side of a divide, and the champions may hold a knife fight to the death. the army would then enforce the deal of the winner's side.

I didn't really get why. Reading Wikipedia articles about AmigaOS and Hyperion wasn't helpful either.

Anyone has insights why this project was started and how is it financed? Not that I object it in any way, lovely to see retro software being maintained. Just being curious.

So in your opinion Israel has planned on having Hamas massacre its citizens on this scale?

The approach over the last decade or so was to keep that border quiet. Usually through economic means, the belief was the naive capitalist notion that lack of money creates evil (crime, war, etc)

Contrary to the popular belief, Israel as evident in the multiple operations l/wars over a decade, did not want to capture the strip. It was obvious that fighting an enemy entrenched in tunnels/hospitals/schools will lead to mass civilian death and IDF soldiers (overstated though). However, in hindsight this also made things worse once that was made inevitable.

You can see it in the Qatar money, agreeing to let dual-use materials that had been used to build tunnels and to allow gazans workers to work in Israel, as recent as just before October 7.

Regarding whether Israeli officials pleaded for that money, that is not an accurate representation, you can read about it here [1]. The reasons include US pressure and cutting funds from the PA to Hamas, and wanting to keep the quiet.

It is also stated they wanted to prevent the establishment of a Palestinian state through counterweighting Hamas and the PA but I think this is a later exercise. This deal was highly unpopular in Israel and was regarded as what it is, protection money

Also, cult, really? Are you always this offensive or only with regard to this topic?

I tried this with the Viture Pro XR glasses last year and it sucks. Can't use it with Linux, except in dumb monitor mode. No head tracking unless you're using a supported OS. Android app sucks becaus you can't use it with any old app, eg productivity apps (their app is like a demo of head tracking that only supports stuff like YouTube and local media). Maybe I should have purchased the Xreals?

Right, no, I wasn't particularly objecting to 6.1, I was pointing at the patch level on it. I would personally take [quickly checks kernel.org] 5.15.180 (latest 5.15) over 6.1.130 (not-latest 6.1), because I'm more concerned with bugfixes than feature releases at this point. If the GKI LTSs are backporting fixes, that may well cover it, although that starts to veer into making me nervous because I rather agree with

> Linux kernel LTS revisions are nothing like LTS revisions of most other projects. They're largely untested patches blindly applied by the LTS maintainers based on patches to mainline being marked for stable backports. If the patches apply cleanly, they ship. If they don't apply cleanly, they largely don't ship. Whether it works is an open question.

I'm also not super fond of frankenkernels. And... I'm confused how you feel about them? If backports suck, shouldn't you want to be chasing the very bleeding edge? I wasn't originally intending to argue that everything had to ride the very latest and greatest, but if backporting is inherently fragile and bug-prone, shouldn't you want to be on the very latest stable version (so as of this writing, 6.14.2)?

> You basically go to war with the military you have.

The war in Ukraine shows what a current-day war looks like: You rapidly expend stockpiled traditional weapons, and then rapidly ramp up low-cost drone manufacturing.

Currently, the #1 drone manufacturer in the world is probably Ukraine, with Russia and China somewhere in the #2 and #3 spots. The United States is somewhere on the bottom of that list.

Subsidising civilian drone manufacturing alone would catch up the United States dual-use manufacturing capability for any potential future war for the next half-a-decade or so. After that...? Something-something-AI-murder-bots.

This isn’t critical thinking. Your complete inability to even vaguely hint or suggest at someone who might be better equipped to either perform this analysis or fund it makes that clear.

“Someone without bias” is a cop out. Everyone has bias, and literally anyone performing or funding air quality measurements is going to have some sort of interest in their outcome. There is no sterile room of blind and deaf eunuchs performing these services and you know that.
