See, this is where you are wrong. The law applies if you target people living in the EU (such as using one of the languages spoken within the EU. English applies thanks to Malta and Ireland. So does not explicitly removing tracking from EU IPs).

Whether it is technically enforceable in your particular case may be the question. But historically, it has been enforced outside the EU.

As you live in the Bay Area - the CCPA and the CPRA, which are similar in many ways and seem to require an opt-out mechanism (e.g. if you operate a commercial website with >100k devices accessing it during a year).

The state of the art solvers are the proprietary ones like Gurobi, FICO, Cplex, Mosek, etc. A major contributor to the proprietary "sauce" is in the heuristics they use. For example, all solvers will have a "presolve" phase which attempts to eliminate redundant constraints/variables. There may be some ML they are using behind the scenes to derive these heuristics, I'm not sure, although I know it is a major research area.

Otherwise, the basic underlying algorithms are all the same, as in the textbook: branch-and-bound and so on.

> The cost of nuke energy is not because the technology is complex or because resources are scarce. It's because we have very, very burdensome regulations around nuclear reactors (for good reason!)

So its easy, at least if it wasn't for all that burdensome regulation. But also the burdensome regulations is actually good, presumably because it's hard to get right.

This sounds like nonsense to me. If the regulation is good, that would usually be because a thing is hard to make work in a liberal society, usually for some misaligned incentive reasons. In that case the regulation isn't "burdensome" but necessary to counteract the failure of the market.

We introduce rStar2-Agent, a 14B math reasoning model trained with agentic reinforcement learning to achieve frontier-level performance. Beyond current long CoT, the model demonstrates advanced cognitive behaviors, such as thinking carefully before using Python coding tools and reflecting on code execution feedback to autonomously explore, verify, and refine intermediate steps in complex problem-solving. This capability is enabled through three key innovations that makes agentic RL effective at scale: (i) an efficient RL infrastructure with a reliable Python code environment that supports high-throughput execution and mitigates the high rollout costs, enabling training on limited GPU resources (64 MI300X GPUs); (ii) GRPO-RoC, an agentic RL algorithm with a Resample-on-Correct rollout strategy that addresses the inherent environment noises from coding tools, allowing the model to reason more effectively in a code environment; (iii) An efficient agent training recipe that starts with non-reasoning SFT and progresses through multi-RL stages, yielding advanced cognitive abilities with minimal compute cost. To this end, rStar2-Agent boosts a pre-trained 14B model to state of the art in only 510 RL steps within one week, achieving average pass@1 scores of 80.6% on AIME24 and 69.8% on AIME25, surpassing DeepSeek-R1 (671B) with significantly shorter responses. Beyond mathematics, rStar2-Agent-14B also demonstrates strong generalization to alignment, scientific reasoning, and agentic tool-use tasks. Code and training recipes are available at this https URL.

Voyager is so far away that from its perspective, earth isn't moving. There is also no force acting on voyager. So practically speaking, compared to the distance between them and the 0.3° beam width, both are hanging pretty still.

It does have an AACS system, which is tracking the sun and a bright star (Canopus) to orient itself earlier in the mission.

A quick search indicates it is still doing about 1 puff per hour to keep pointing the right way. The biggest problem seems to be that the lines for those puffs are clogging.
Show HN: AuctionHubIndia – Discover Bank Auction Properties Across India
by raooll | 2025-09-09 06:24:09+00:00
Hi HN,

I’ve been working on AuctionHubIndia , a platform that aggregates bank auction properties (residential and commercial) across India.

Banks regularly auction distressed assets (NPAs, SARFAESI, foreclosures), but the notices are scattered across dozens of bank sites, often as unstructured PDFs or poorly formatted web pages. Finding and tracking them is tedious.

What it does:

Aggregates auction listings from multiple Indian banks.

Uses AI agents to parse and process unstructured notices into clean, searchable property data.

Lets you filter by location, property type, price, bank, and more.

Provides timely updates so buyers never miss an auction.

Why we built it: For investors and homebuyers, the current system is fragmented and opaque. AuctionHubIndia makes the process transparent, searchable, and easy to navigate.

What’s next:

Advanced search capabilities with smarter filters.

Free downloads of up to 4 listings before subscription.

Weekly rollout of new user-friendly features.

Would love to hear your feedback, especially around improving discovery or automating due diligence.

Check it out: https://auctionhubindia.com

That kind of reconstruction effort only happens with a huge budget, which means for most of these technologies, it never happens at all. Academic papers only give a basic starting point; especially for materials science, people dedicate the span of their entire years to developing manufacturing processes beyond what ever gets published in public. With enough motivation you can have the pleasure of following their footsteps, but it will consume more than one lifetime to do so. And nobody will fund that rediscovery effort, because there's no money in niche industries.

A result of this is that, in some rare cases, there are certain machines and instruments where the best ones in existence were manufactured in the '80s and are jealousy hoarded in temperature-controlled vaults, because nobody today can make a better one and the industry that produced them is completely gone.

FOGBANK is a great example of a lost technology that had to be rediscovered at great expense, and that only happened because the military could write a blank cheque. But that's exactly a lost technology; they had to do the R&D all over again. And even then, they didn't have to make up for a bigger market that vanished; they were always the only customer for FOGBANK, so the economics hadn't changed. Imagine if the economically producing that material required a customer base the size of Kodak's peak market share to amortize the capital cost of a production run.

Most technologies don't have infinite money available to recreate from scratch; they depend on economies of scale and die out with their markets.

The main selling point for source code in plain text files is compatibility. You can use whatever tool you wish. Yes, it's not ideal, and yes, we are still using non-semantic diffs in these days, even though it should have been a solved problem by now. I'd still argue that even if all the editing/VCS tools start working in a structured way, the storage format should be plain text.
by Eikon | 2025-09-09 06:25:27+00:00
I have no doubt that JuiceFS can perform “thousands of operations per second” across parallel clients. I don't think that's a useful benchmark because the use cases we are targeting are not embarrassingly parallel.

Using a bunch of clients on any system hides the latency profile. You could even get your "thousands of operations per second" on a system where any operation takes 10 seconds to complete.

It was a valiant effort by AMD when they made their first attempt at an in-house x86 chip design. Prior to this, AMD effectively cloned Intel designs under license.

Sadly, the K5 was pretty underwhelming upon release, and it wasn’t until AMD acquired NexGen and integrated their special sauce into their next version core, the K6, that things started getting interesting. I was quite fond of my old AMD K6 II+ based PC back in the day. It had good value for the money.

Then you see the K7/Athlon core, complete with inspiration from the DEC Alpha thanks to none other than Jim Keller, and AMD was on a serious tear for a good while after that, beating Intel to 1 GHz.

I agree that it is a mostly well managed product, but I can think of a lot of things when it was in the news for something bad. Most controversial is probably the increase in the amount of Ads, unskippable ads, then there was multiple problems with Youtube kids, e.g. how bad people get really bad videos there. There was an outcry when the dislike button was removed, and so on..
by CuriouslyC | 2025-09-09 06:26:10+00:00
Claude Code is indeed legit bad. You'd never know that this was a billion dollar company by the mess of javascript they hacked together. You have to periodically close and re-open the client because otherwise it starts to lag the system from constantly scanning and saving a big JSON file, and they didn't think to shard their storage or use a database. I have 128GB of ram on my workstation and running 8 claude code instances at once sometimes causes heavy thrashing and desktop responsiveness issues... That's just insane.

Needless to say I built my own agent (just needs a good web UI, last step!). The only thing keeping me with anthropic right now is the economics of the plan, my inference bill would be a second mortgage without it.

I do feel entitled to unlimited video streaming for free. Since the invention of bittorrent there is no need to have a client-server middleman for distributing large files like videos.

If the bandwidth bankrupts them, then boo hoo. They take advantage of network effects so no one can go anywhere else.

Don't feed the bears. That's what I say

It depends on how intelligence is defined. In the traditional AI sense it is usually "doing things that, when done by people, would be thought of as requiring intelligence". So you get things like planning, forecasting, interpreting texts falling into "AI" even though you might be using a combinatorial solver for one, curve fitting for the other and training a language model for the third. People say that this muddies the definition of AI, but it doesn't really need to be the case.

Sentience as in having some form of self-awareness, identity, personal goals, rankings of future outcomes and current states, a sense that things have "meaning" isn't part of the definition. Some argue that this lack of experience about what something feels like (I think this might be termed "qualia" but I'm not sure) is why artificial intelligence shouldn't be considered intelligence at all.

You've made me realize that I probably have a subconscious bias against science and engineering.

My view of the ideal math curriculum is very humanistic, focusing on the broad civic and intellectual value of formal reasoning, statistical fluency, etc. I never liked the in-the-weeds numerical stuff you get in science and engineering, but it's what the world is built on.

`rclone mount` an `rclone crypt` over a Cloudflare R3 backend of `rclone`? Or if it's sufficiently often "off/idle", take 3 USB HDDs (1~2 years ago I bought an iirc WD MyPassport 5TB for very similar workload) into a RAID-5 and have appropriate off-site backup that you actively check to have successfully gotten the latest daily backup's file contents (check a couple (3~5) random files as well as a few (3~5 ish) critical/database/metadata files) at least every 1~3 months.

Also, as opportunities arise like for example from a major upgrade to local storage capacity, try to fully test a backup restore emulated to "your home burned to the ground while you were at the office/on holiday" conditions every 1~3 years if you can afford to spend the bandwidth for it.

Consider burning in drives for a group-buy you do with local friends if necessary to at least get such a full restore trial every about 3 years. Try as best to consider a trial every about 5 years to be a "cost of doing business" that's not just nice to have but essential to the value proposition of the data archive storing home server.

Oh and yeah, I fully mean to let the drives go to sleep when you're not accessing them through "manual"/interactive means (exceptions are limited-time background queued work with a set override timer, and the daily backup runs, which will also unlock the drives from their regular sleep-doesn't-get-interrupted-for-no-good-reason enforcement; ofc this is all something you do only if you can and feel like you want to: just hunting down rouge accesses/wake-ups happening at odd times by setting up some minor logging of which programs/files/accesses (or at the very least _when exactly_) are causing the drives to wake up is something you could very well get away with). Also take care to ensure they get good airflow: stack them with gaps between and ideally just take a decent but low-cost 120mm fan that you just hook to 5V from USB (if you don't have a fan header laying around) and rig with some cardboard and tape to channel air across your drives. The drives want to be around 30~45 C, consider hooking the smart temperature readout to a kill switch in case of fan failure.

You also accumulate screen time if you are using navigation while commuting, etc. I easily rack up 2 hours daily just from driving to my workplace and back home, so there are definitely some "passive" ways to increase those numbers.

I think focusing on numerical stats here is also a bit of a problem and while making these guardrails might help some people but the main issue should be addressed (overconsumption/addiction).

I wonder by reducing the screen time of the phone, how the screen time of the other devices (computer/tv/etc) changed.

Syncthing is just open source Dropbox, self hosted.

It's entire purpose is "make two folders identical".

It's very good at that: so good that I frequently wish it did other things - i.e. if it had some notion of minimum seeding levels so it would destage files off a device provided they were replicated elsewhere (e.g. automatically clearing old photos off your phone would be a good use of it).

As other's have already mentioned, currently I am using Tailscale. But I plan to somewhere in the future change that to something a bit more controlled by myself. Like a self hosted Wireguard VPN on some VPS.

I was also thinking about just reverse proxying my local instance to some public domain. But currently do not trust immich to be safe enough to allow for public exposure.

I agree that multiplying 42x37 is not difficult. Many western mental calculators can do so quickly. I also agree that grinding, memorization, and tricks play a role in mental math.

> the correlation between Asia and mental math + abacus is spurious

However, I do not think the correlation is spurious. Involving additional brain areas like premotor (imagining moving the beads) and parietal (seeing the beads) is likely responsible for the incredible speeds achieved by trained abacus users. https://doi.org/10.1016/S1053-8119(03)00050-8

Western mental addition operates on fundamentally different timescales. Here's Aaryan Shukla adding 100 4-digit numbers in 300ms per number: https://www.youtube.com/watch?v=6ouUk0zIbos

OH MY GOD YES! I actually had it inject synthetic data into my experiments! I had to go back through all my work and re-validate so much to make sure I found all instances of it (it happened in a few different projects).

I now have a system of automated tripwires on all experimental scripts that notifies me and terminates the experiment when any sort of statistical irregularity is detected.

Note however, that you can't use diff on binaries, [...]

You absolutely can, but you need to use an external diff tool:

fossil diff --command "compare"

You can also customise the diff-command variable. You might need to pass --diff-binary .. I forgot.

As for storing binaries, unversioned files have no history, and are not synced automatically.

I have question on a related note. Why do public fora like HN and the western society in general, frown upon and harshly censor any comparisons of contemporary human actions with Nazi tactics (and explicitly not the magnitude of their consequences), made in order to highlight the underlying human behavior? The responses are as if they just saw Nazism or the Holocaust being glorified. Many replies often contain such exaggerated and inordinate amount of outrage that it makes you wonder if they witnessed the holocaust in person (in which case, the response would be justified on account of trauma. But the incident was 80 years ago).

There is no question that the Holocaust was a horrific chapter in human history. But that extreme nature is also what makes it a treasure trove of references for human behavior - be it bad or good (like the heroics and selflessness of those who opposed it). Isn't that why we learn history? To reference it when relevant and to prevent a repeat of the past mistakes? Now especially, since Nazism is rearing its ugly heads again in multiple places on the planet, quite overtly at times. Instead, it's now difficult to draw any such parallels in human psychology for the fear of accidentally offending some people's fragile sensitivities. I still don't understand what it is that they get so offended about. The entire reaction feels quite pretentious and has strong vibes of virtue signalling and gatekeeping.

> Forecasts indicate that by 2055 England’s public water supply could be short by 5bn litres a day

> Water companies in England and Wales lose about 1tn litres of water through leaky pipes each year.

Seems like there's most of a solution here, just staring us in the face, no? Problem being of course, that the privatised water companies have little incentive or investment in order to tackle the problem.

Are we ready to admit that selling off critical national infrastructure was a stupid idea, yet?

It's the same story with power and gas, wherever they get turned over to the private sector, things get worse. Fundamentally I don't give the first shit about choosing an energy provider. I don't want to find a new deal every few years. I don't give a shit about choice, I just want someone to do it well and charge reasonably. Instead you get stuck in a market offering discounted signup rates and you have to switch every year, while the companies draw their earnings from the minority of people who forget or otherwise can't be bothered to switch.

I don't miss that from the UK. Here in communist Western Australia we maintained ownership of the water, power and gas infrastructure, where other parts of the country set up privatised energy marketplaces. When the UK and the rest of Australia were screaming about rocketing bills, we were protected from some of the fluctuations in international energy prices over the last few years and any profits got ploughed back into infrastructure or the state coffers rather than heading off to private hands. It's just better...

> which unfortunately stifles other open alternatives by the virtue of being "good enough".

In China at least, the hardware companies are smart enough to not put all eggs in the RISC-V basket, and are pursuing other open/non-encumbered ISAs.

They have LoongArch which is a post-MIPS architecture with elements from RISC-V. Also they have ShenWei/SunWay which is post-Alpha.

And they of course have Phytium (ARM), HeXin (OpenPower), and Zhaoxin (x86).

Signal has over $50m in endowments.

But their desktop app is built with electron.

It's extremely clunky (over 200 MB) very slow and probably inherits all electron's security issues.

I have noticed the same issue with desktop apps from Proton Mail.

Why is it that rich corporations with lots of money like shortcuts and don't care about the quality of thier software?

Paying to remove ads is negotiating with terrorists.

YouTube stays in the dominant position either way, it's not like tomorrow you'll go watch Nebula exclusively (you'd already have done it at this point). They're not providing anything materially, so the amount you pay is bound to nothing except how much you're willing to pay. And how much you're willing to pay depends on how much you're annoyed.

So YouTube's main incentive for this program is to annoy you as much as you can tolerate to optimize the most money you get extracted.

I disagree entirely. I think that this "quibble" is just cope.

People don't want machines to infringe on their precious "intelligence". So for any notable AI advance, they rush to come up with a reason why it's "not ackhtually intelligent".

Even if those machines obviously do the kind of tasks that were entirely exclusive to humans just a few years ago. Or were in the realm of "machines would never be able to do this" a few years ago.
