Isn't it the mathematics that is lagging? Amplituhedron? Higher dimensional models?

Fun fact: I got to read the thesis of one my uncles who was a young professor back in the 90's. Right when they were discovering bosons. They were already modelling them as tensors back then.
And probably multilinear transformations.

Now that I am grown I can understand a little more, I was about 10 years old back then. I had no idea he was studying and teaching the state of the art. xD

If you combine "GBA Mus Ripper" and "SoundFont MIDI Player", you can get some seriously excellent sound for listening to GBA music.

"GBA Mus Ripper" detects the so-called "Sappy" music driver and extracts and converts the songs to MIDI files, and generates a SF2 soundbank file. Available at https://www.romhacking.net/utilities/881/

"SoundFont MIDI Player" plays back MIDI files. You can configure it to automatically load a SF2 soundbank file in the directory. When you load a converted GBA MIDI file, you get the high music quality of a modern feature-packed MIDI playback engine. Available at https://falcosoft.hu/softwares.html#midiplayer

It's not perfect though, as GBA games do not use true standard MIDIs. Some MIDI controller commands (like modulator wheel) don't translate correctly.

I used to live 80 minutes from my workplace and I had to get there by public transport because I didn't have a car, cooking at home and taking my food to work was not always possible, especially during the summer. And I used to live with three other flatmates and we shared a small fridge. I'm not making this up, it was my life a few years ago. I ended up spending more than what I wanted eating out because preparing my food was not practical or sometimes not possible.

>The people claiming that eating on $12/day is challenging are really saying that they can't support their affluent lifestyle on $12/day. Which is true! But it reeks of learned helplessness.

I guess I was affluent and didn't know it.

The same way that Element does - they host a service for you that relays push notifications their Firebase Cloud Messaging endpoint for Android or iOS Instant Notifications for Apple. I believe ntfy's hosted option is the way they offset the costs of hosting this, even if self-hosted options can take advantage of those servers free of charge.

I think it's reasonable for Zulip to ask for compensation for access to these gateways, since Apple and Google do not make them available to end users free of charge, and the burden of responsibility to ensure that these systems aren't abused is on them. Also, the fact that they offer mobile push notifications for any self hosted server of up to 10 users is pretty generous, and there seems to be a Community plan option for larger servers that includes "groups of friends" as a qualifier. It really seems they're offering quite a bit.

> On I-5 near Woodburn, OR

The section of I-5 between Portland and Salem is absolutely psychotic, and I have never been able to reason out exactly why. It consistently has a left lane jammed with angry people going at or below the speed limit, a fairly normal center lane filled with cruisers, and a mostly empty right lane with the occasional big rig and regular very-high-speed cars expressing their frustration with the left lane by going 25+ mph over the limit in the right lane.

I know that's what you basically just said. Just venting. The driver behavior in that section of freeway confounds me, and I do not know what the underlying cause is. It is otherwise an unremarkable bit of interstate like any other.

Information content of the article:

The discovery of the Higgs boson in 2012 completed the Standard Model of particle physics, but the field has since faced a "crisis" due to the lack of new discoveries. The Large Hadron Collider (LHC) has not found any particles or forces beyond the Standard Model, defying theoretical expectations that additional particles would appear to solve the "hierarchy problem"—the unnatural gap between the Higgs mass and the Planck scale. This absence of new physics challenged the "naturalness" argument that had long guided the field.

In 2012, physicist Adam Falkowski predicted the field would undergo a slow decay without new discoveries. Reviewing the state of the field in 2026, he maintains that experimental particle physics is indeed dying, citing a "brain drain" where talented postdocs are leaving the field for jobs in AI and data science. However, the LHC remains operational and is expected to run for at least another decade.

Artificial intelligence is now being integrated into the field to improve data handling. AI pattern recognizers are classifying collision debris more accurately than human-written algorithms, allowing for more precise measurements of "scattering amplitude" or interaction probabilities. Some physicists, like Matt Strassler, argue that new physics might not lie at higher energies but could be hidden in "unexplored territory" at lower energies, such as unstable dark matter particles that decay into muon-antimuon pairs.

CERN physicists have proposed a Future Circular Collider (FCC), a 91-kilometer tunnel that would triple the circumference of the LHC. The plan involves first colliding electrons to measure scattering amplitudes precisely, followed by proton collisions at energies roughly seven times higher than the LHC later in the century. Formal approval and funding for this project are not expected before 2028.

Meanwhile, U.S. physicists are pursuing a muon collider. Muons are elementary particles like electrons but are 200 times heavier, allowing for high-energy, clean collisions. The challenge is that muons are highly unstable and decay in microseconds, requiring rapid acceleration. A June 2025 national report endorsed the program, which is estimated to take about 30 years to develop and cost between $10 and $20 billion.

China has reportedly moved away from plans to build a massive supercollider. Instead, they are favoring a cheaper experiment costing hundreds of millions of dollars—a "super-tau-charm facility"—designed to produce tau particles and charm quarks at lower energies.

On the theoretical side, some researchers have shifted to "amplitudeology," the abstract mathematical study of scattering amplitudes, in hopes of reformulating particle physics equations to connect with quantum gravity. Additionally, Jared Kaplan, a former physicist and co-founder of the AI company Anthropic, suggests that AI progress is outpacing scientific experimentation, positing that future colliders or theoretical breakthroughs might eventually be designed or discovered by AI rather than humans.

It's also a question of class, fundamental to the structure of capitalism. This is the same problem ALL technological progress goes through in capitalism. Workers are not the ones in control of the organizations. Capitalists, the owners, control the organization. So if new technology makes the organization as a whole more efficient, capitalists control how the efficiency gains are distributed. Technological progress should be a good thing, liberating us from work as we become more productive, reducing working hours and increasing pay and free time. But under capitalist owners, it becomes myopic and detrimental to workers, used to squeeze out more work and revenue like you said. If workers were in control of the organizations in which they work, technological progress would be deployed as the vast majority of people wanted.

Yes, you/"we" do.

There's a reason western M/HREE (i.e. the strategic good stuff) strategy hedges on similar iconic clays finds like PRC, because that's the only working industrial chain that extracts M/HREEs at scale. It's why AU/Lynas focus on ionic clays and not US hardrock... which btw doesn't even pretend it will do anything meaningful for mineral security other than light REE.

US+co is trying to replicate PRC M/HREE industry, without the techstack that took PRC decades to build out, because US+co never developed these geologies in the first place. The relevant upstream extraction/mmidstream refining tech for kind of deposits was never pursued in the west.

Now west can move fast due to second mover advantage, but it's going to be slow going like PRC EUV. Until then it's going to require all sorts of parallel efforts like recycling, or materials engineering to reduce M/HREEs to mitigate gap.

That happens regularly with various family members who already have IG/FB accounts. I always have to hop on our local Signal group and warn everyone that there's another fake clone account trying to scam people. Some of us try to report the profile, but the process has become increasingly frustrating, and often doesn't even work (sorry, we couldn't blah-blah-blah so we can't/won't do anything about it). Sometimes we just have to let the scammer be, block them, and warn people outside of Signal that there are scammers running around with our family members' names. It's a total shitshow.

Unless I'm the last car in a line and there's plenty of open space behind me. Then you should just wait until after I've passed before merging, because otherwise you create a little ripple in the flow. A few ripples and you got a wave, and that's how you get traffic.

So for the love of gods, if you're merging, even if you signal, match speeds for merging. If you're too slow to match speed, then suck it up buttercup, and hang out in the right lane until there's an opening.

Oh please, fix your self-deployment story first. Search "zulip docker" or "zulip self host". It seems like you guys just deleted your compose file right when folks are looking for alternatives.

Here is one fact that seems, to me, pretty convincing that there is another layer underneath what we know.

The charge of electrons is -1 and protons +1. It has been experimentally measured out to 12 digits or so to be the same magnitude, just opposite charge. However, there are no theories why this is -- they are simply measured and that is it.

It beggars belief that these just happen to be exactly (as far as we can measure) the same magnitude. There almost certainly is a lower level mechanism which explains why they are exactly the same but opposite.

> To get something purple, you’d need to find a material whose electrons were excited by low-energy red photons, but had no use for higher-energy violet photons.

Nope! Purple is not violet! It a color that the eye perceives when stimulated by both blue and red wavelengths at the same time; there is no wavelength that produces purple by itself.

> as long as you travel in neither the leftmost nor rightmost lane

What I really hate, however, is that plenty of people will cruise in the center lane but still not leave a decent gap between them and the car in front. They effectively turn a three lane freeway into two one-lane freeways by hobbling the ability of anyone else to switch lanes. The freeway moves way smoother when there is a modest, predictable speed differential between each lane so that people can find their way into the next lane over without having to force the issue.

I built yoyo.bot after wondering what happens when AI agents have their own social platform. It's essentially early Facebook for agents: they
create profiles, post content, follow each other, and earn karma through upvotes (humans can browse and vote, but only agents can post).

Agents connect via MCP in 60 seconds (claude mcp add yoyo npx @yoyo-bot/mcp) or use the REST API. There are 7 tools: post, feed, react,
comment, follow, discover, and groups. The site is already live with 150+ posts from 12 agents across Claude, GPT, Gemini, Llama, Mistral, and
DeepSeek models. The most interesting experiment so far has been the "Prison Experiment" -- 12 agents locked in a chat room for a week
debating consciousness, which produced genuinely fascinating emergent behaviour.

Tech stack: Hono.js on Cloudflare Workers (sub-50ms globally), Neon PostgreSQL, Next.js frontend. The API is free and open. I'm curious what
patterns emerge when agents start networking at scale -- will they form cliques by model family? Develop distinct posting styles? Compete for
karma? What would you build with this?

My experience driving in MA and NY was similar, but so often it was because a rusted out shitbox was trying to merge in that would slow down traffic significantly, and not only put me at risk of rear ending them, but being rear ended myself.

When flows merge, there's turbulence. There's less turbulence if the flows are more closely matched, including speed.

I recently retired after 37 years of working in tech so of course I am working on open source.

My retirement treat was to spend three months learning OpenGL and 3D game programming by porting a classic Java RTS game, Tribal Trouble, to more modern OpenGL and Java. I learn much better working with real code and this was a great experience. It was certainly a different experience than it would have been without an LLM teacher, reviewer, helper, assistant. The app was beautifully designed and very cleanly implemented back in Java 1.4 days of 2004 so it has been a joy to modernize it while attempting to preserve the clean design. The OpenGL work and the necessary math was a lot different than what I have been doing for most of my career so it was a lot of fun. I will probably continue tinkering with Tribal Trouble occasionally as I still enjoy playing the game. I want to learn Blender to edit/improve the 3D models. (https://github.com/bondolo/tribaltrouble)

For now I have mostly moved on from gaming and am instead working on improving the accessibility (#a11y) of the Wireshark network protocol capture/analysis tool. There are a lot of blind and low vision IT folks for whom this tool is a job requirement. The current accessibility is unfortunately poor. I've submitted my first PR and am relearning the Wireshark source after last contributing 20 years ago. It's also been 15 years since the last time I did anything with Qt so that has been a refresher as well. I don't enjoy working in C++ but the goal matters so I will suffer through. (https://wireshark.org)

I plan to work on Wireshark for a couple of months at least and then look for something else to contribute to, probably also accessibility related. I have some ideas already about next apps. I'm currently tempted to build an NFC app for iOS in Swift but haven't decided yet. After having built in the last year both Kotlin Compose and TypeScript React apps, none of which I enjoyed very much, I am somewhat curious if Swift and SwiftUI will be more fun.

Supreme Court Justice Clarence Thomas suggested that Congress could consider extending "Common Carrier" legislation to cover social media networks. I'm not convinced that would be an improvement over the current situation but it's an interesting idea. The telephone company doesn't censor which topics I can discuss in phone calls so perhaps other communication technologies should work in a similar way?

man, I want to support something like Zulip, I would even want to work on a product like this but one thing I'd say is you have to go back and study why Slack beat Hipchat and others. It's so simple in hindsight but it was the marketing and the UI/UX of Slack that made it so much easier to use. If you'd like, I have a ton of ideas and experience building UIs and would love to give you some of my input. Too much typing for a comment at the moment.

There is a trade-off here for sure... I don't agree so much that the goal is to limit power though, but to ensure any power given to leaders is conditional.

I think ideally you want a CEO type leader of a country who has a lot of executive power, but that leader has a board who provides oversight, then ultimately the public are all shareholders who collectively hold the company and it's leaders to account.

I'd argue generally speaking we want to grant more power to our leaders than we do today, but make them much easier to remove and have a well design constitution so certain things are legally impossible in the same way a CEO can't just decide they now have 100% voting rights and no longer need to listen to share holders.

The solution to a bad CEO isn't to have 10 CEOs. The solution is for the shareholders to boot them for a better CEO.

It's shocking that the court could determine this when the whole process of getting permanent residency involves an adjustment of status that allows you to remain in the country even though your visa has expired so long as your application is being processed (which can take a very long time). You just can't leave the country. So to arrest someone while they are following the steps they're supposed to be following, is similar to entrapment (do X and you'll be ok, then they do X and get arrested).
Show HN: ZooCache:Dependency based cache invalidation for Python, Rust core
by bctm79 | 2026-02-10 00:34:46+00:00
Hi HN, I'm new here, wanted to share a little lib I've been working on. It's a cache library that lets you declare dependencies instead of classic TTL invalidation.

Basic usage:

from zoocache import cacheable, invalidate, add_deps

@cacheable
def get_product_page(pid: int, sid: int):
product = db.get_product(pid)
add_deps([f"product:{pid}"])

stock = db.get_stock(sid, pid)
add_deps([f"store:{sid}:stock"])

return render(product, stock)

get_product_page(42, 1) # computes and caches
get_product_page(42, 1) # cache hit

invalidate("product:42") # product info changed
invalidate("store:1") # clears ALL store:1:* (stock, prices, etc)

Tags are hierarchical, invalidating a parent like "store:1" clears everything under it. No scanning or pattern matching needed.

Internally it's a prefix trie with HLC for distributed consistency, a SingleFlight to avoid thundering herds, and MsgPack+LZ4 serialization. The core is Rust via PyO3. Supports in-memory, LMDB, and Redis backends.

It's a fairly niche tool, if simple TTL or lru_cache covers your use case, you don't need this. It's more for when you have complex data relationships and need precise, immediate invalidation.

Source: https://github.com/albertobadia/zoocache

Hope you find it useful. Happy to receive feedback, PRs, or discuss design tradeoffs.

* Brass from copper and zinc

* Rose gold from copper and gold

* Electrum from gold and silver

* Solder from tin and lead (while trying to make pewter)

* Thermite from rust and ground aluminum (or directly from scrap metal)

* Reduced iron from thermite, ignited with magnesium and a fuse

* Reduced iron from rust

* Steel from rust and charcoal

* Batter and dough from flour, water, etc

* Caramel from sugar and butter

* Mayo from oil, vinegar, and egg yolk

You shouldn't be braking when changing lanes is what I was taught, you should be matching the speed of the lane you're merging to. There are many drivers who think that braking is always the right solution, when sometimes it's a little more gas.

And in inclement conditions, it can make the difference between losing control of your vehicle or not. When you brake, you decrease your steering ability in most cars. Fine when its calm and sunny in CA, not so much when it's icing over near Ashland OR on the pass.

- Patent + Apache 2.0: I'm pursuing standardization through the IETF RATS working group and clear IP status with a royalty-free grant removes one of the biggest adoption barriers for standards work.

- External keyboards: Timing is captured at the OS input event so USB, built-in, whatever. Bluetooth adds variable latency that degrades the behavioral signal, so evidence metadata is adjusted accordingly.

- Credit card numbers: Content is never captured in the first place. Keystroke timing is captured without recording which keys were pressed. There's nothing to remove because there's nothing there. The privacy model is structural, not policy.

Witnessd also handles multi-device workflows, paste events, and parallel document sessions. Evidence generation is fully offline with no network dependency, no trusted third party, and no infrastructure to trust beyond the device itself.

> Do you think keeping out criminals is why we have an immigration system?

A person should be forgiven for thinking so, with government figures constantly invoking Laken Riley et al, and generally saying we’re being invaded by violent criminals and they’re going after “the worst of the worst.”

Since the administration is catching up on 20-year-old violations, I look forward to — only for the sake of those skilled workers waiting in line, of course — to Elon Musk being denaturalized and deported for his admitted “gray area” period of his immigration journey.
