Elon Musk proposes putting the U.S. Treasury on blockchain for full transparency

FedNow supports ILP Interledger Protocol, which is an open spec that works with traditional ledgers and distributed cryptoasset ledgers.

> In addition to Peering, Clearing, and Settlement, ILP Interledger Protocol Specifies Addresses: https://news.ycombinator.com/item?id=36503888

>> ILP is not tied to a single company, payment network, or currency

ILP Addresses - v2.0.0 > Allocation Schemes: https://github.com/interledger/rfcs/blob/main/0015-ilp-addre...

People that argue for transaction privacy in blockchains: large investment banks, money launderers, the US Government when avoiding accountability because natsec.

Whereas today presumably there are database(s) of checks sent to contractors for the US Gvmt; and maybe auditing later.

Re: apparently trillions missing re: seasonal calls to "Audit the Fed! Audit DoD!" and "The Federal Funding Accountability and Transparency Act of 2006" which passed after Illinois started tracking grants: https://news.ycombinator.com/item?id=25893860

DHS helped develop W3C DIDs, which can be decentralizedly generated and optionally centrally registered or centrally generated and registered.

W3C Verifiable Credentials support DIDs Decentralized Identifiers.

Do not pay for closed source or closed spec capabilities; especially for inter-industry systems that would need to integrate around an API spec.

Do not develop another blockchain; given the government's inability to attract and retain talent in this space, it is unlikely that a few million dollars and government management would exceed the progress of billions invested in existing blockchains.

There's a lot of anti-blockchain FUD. Ask them to explain the difference between multi-primary SQL database synchronization system with off-site nodes (and Merkle hashes between rows), and a blockchain.

Why are there Merkle hashes in the centralized Trillian and now PostgreSQL databases that back CT Certificate Transparency logs (the logs of X.509 cert granting and revocations)?

Why did Google stop hosting a query endpoint for CT logs? How can single points of failure be eliminated in decentralized systems?

Blockchains are vulnerable to DoS Denial of Service like all other transaction systems. Adaptive difficulty and transaction fees that equitably go to miners or are just burnt are blockchain solutions to Denial of Service.

"Stress testing" to a web dev means something different than "stress testing" the banks of the Federal Reserve system, for example.

A webdev should know that as soon as your app runs out of (SQL) database connections, it will start throwing 500 Internal Server error. MySQL, for example, defaults to 150+1 max connections.

Stress testing for large banks does not really test for infosec resource exhaustion. Stress testing banks involves them making lots of typically large transactions; not lots of small transactions.

Web Monetization is designed to support micro payments, could support any ledger, and is built on ILP.

ILP makes it possible for e.g. 5x $100 transactions to be auditably grouped together. Normal, non bank of the US government payers must source liquidity from counter parties; which is easier to do with many smaller transactions.

Why do blockchains require additional counterparties in two party (payer-payee) transactions?

To get from USD to EUR, for example, sometimes it's less costly to go through CAD. Alice holds USD, Bob wants EUR, and Charlie holds CAD and EUR and accepts USD, but will only extend $100 of credit per party.

ripplenet was designed for that from the start. Interledger was contributed by ripplecorp to W3C as an open standard, and ILP has undergone significant revision since being open sources.

ILP does not require XRP, which - like XLM - is premined and has a transaction fee less than $0.01.

Ripplenet does not have Proof of Work mining: the list of transaction validator server IPs is maintained by pull request merge consensus in the GitHub repo.

The global Visa network claims to do something like 60,000 TPS. Bitcoin can do 6-7 TPS, and is even slower if you try and build it without blocks.

I thought I read that a stellar benchmark reached 10,000 TPS but they predicted that the TPS would be significantly greater with faster more expensive validation servers.

E.g. Crypto Kitties NFT smart contract game effectively DoS'd pre-sharding Ethereum, which originally did 15-30 TPS IIRC. Ethereum 2.0 reportedly intends to handles 100,000 TPS.

US Contractor payees would probably want to receive a stablecoin instead of a cryptoasset with high volatility.

Some citizens received a relief check to cash out or deposit, and others received a debit card for an account created for them.

I've heard that the relief loan program is the worst fraud in the history of the US government. Could any KYC or AML practices also help prevent such fraud? Does uploading a scan of a photo ID and/or routing and account numbers on a cheque make exchanges more accountable?

FWIU, only Canadian banks give customers the option to require approval for all deposits. Account holders do not have the option to deny deposits in the US, FWIU.

I don't think the US Government can acquire USDC. Awhile back stablecoin providers were audited and admonished.

A reasonable person should expect US Government backing of a cryptoasset to reduce volatility.

Large investment banks claimed to be saving the day on cryptoasset volatility.

High-frequency market makers claim to be creating value by creating liquidity at volatile prices.

They eventually added shorting to Bitcoin, which doesn't account for debt obligations; there is no debt within the Bitcoin network: either a transaction clears within the confirmation time or it doesn't.

There are no chargebacks in Bitcoin; a refund is an optional transaction between B and A, possibly with the same amount less fees.

There is no automatic rebilling in Bitcoin (and by extension other blockchains) because the payer does not disclose the private key necessary to withdraw funds in their account to payees.

Escrow can be done with multisig ("multi signature") transactions or with smart contracts; if at least e .g. 2 out of 3 parties approve, the escrowed transaction completes. So if Alice escrows $100 for Bob conditional upon receipt of a product from Bob, and Bob says she sent it and third-party Charlie says it was received, that's 2 out of 3 approving so Alice's $100 would then be sent to Bob.

All blockchains must eventually hard fork to PQ Post Quantum hashing and encryption, or keep hard forking to keep doubling non-PQ key sizes (if they are not already PQ).

PQ Post Quantum algos typically have a different number of characters, so any hard fork to PQ account keys and addresses will probably require changing data validation routines in webapps that handle transactions.

The coinbase field in a Bitcoin transaction struct can be used for correlating between blockchain transactions and rows in SQL database that claim to have valid data or metadata about a transaction; you put a unique signed value in the coinbase field when you create transactions, and your e.g. SQL or Accumulo database references the value stored in the coinbase field as a foreign key.

Crypto tax prep services can't just read transactions from public blockchains; they need exchange API access to get the price of the asset on that exchange at the time of that transaction: there's no on-chain price oracle.

Show HN: PulseBeam – Simplify WebRTC by Staying Serverless

WebRTC’s capabilities are amazing, but the setup headaches (signaling, connection/ICE failures, patchwork docs) can kill momentum. That’s why we built PulseBeam—a batteries-included WebRTC platform designed for developers who just want real-time features to work. What’s different? Built-in Signaling Built-in TURN Time limited JWT auth (serverless for production or use our endpoint for testing) Client and server SDKs included Free and open-source core If you’ve used libraries like PeerJS, PulseBeam should feel like home. We’re inspired by its simplicity. We’re currently in a developer-preview stage. We provide free signaling like PeerJS, and TURN up to 1GB. Of course, feel free to roast us

Unattended upgrades fail and sit there requiring manual intervention (due to lack of transactional updates and/or multiple flash slots (root partitions and bootloader configuration)).

Pull style configuration requires the device to hold credentials in order to authorize access to download the new policy set.

It's possible to add an /etc/init.d that runs sysupgrade on boot, install Python and Ansible, configure and confirm remote logging, and then run `ansible-pull`.

ansible-openwrt eliminates the need to have Python on a device: https://github.com/gekmihesg/ansible-openwrt

But then log collection; unless all of the nodes have correctly configured log forwarding at each stage of firmware upgrade, pull-style configuration management will lose logs that push-style configuration management can easily centrally log.

Pull based updates would work on OpenWRT devices if they had enough storage, transactional updates and/or multiple flash slots, and scheduled maintenance windows.

Quantum Bayesian Inference with Renormalization for Gravitational Waves

ScholarlyArticle: "Quantum Bayesian Inference with Renormalization for Gravitational Waves" (2025) https://iopscience.iop.org/article/10.3847/2041-8213/ada6ae

NewsArticle: "Black Holes Speak in Gravitational Waves, Heard Through Quantum Walks" (2025) https://thequantuminsider.com/2025/01/29/black-holes-speak-i... :

> Unlike classical MCMC, which requires a large number of iterative steps to converge on a solution, QBIRD uses a quantum-enhanced Metropolis algorithm that incorporates quantum walks to explore the parameter space more efficiently. Instead of sequentially evaluating probability distributions one step at a time, QBIRD encodes the likelihood landscape into a quantum Hilbert space, allowing it to assess multiple transitions between parameter states simultaneously. This is achieved through a set of quantum registers that track state evolution, transition probabilities, and acceptance criteria using a modified Metropolis-Hastings rule.

> Additionally, QBIRD incorporates renormalization and downsampling, which progressively refine the search space by eliminating less probable regions and concentrating computational resources on the most likely solutions. These techniques enable QBIRD to achieve accuracy comparable to classical MCMC while reducing the number of required samples and computational overhead, making it a more promising approach for gravitational wave parameter estimation as quantum hardware matures.

But the cost of a wrong answer (wrongful conviction) exceeds a threshold of ethical use.

> We try prompt engineering techniques to spur the LLM to act more like human judges, but with no success. “Judge AI” is a formalist judge, not a human judge.

37D boundary of quantum correlations with a time-domain optical processor

"Exploring the boundary of quantum correlations with a time-domain optical processor" (2025) https://www.science.org/doi/10.1126/sciadv.abd8080 .. https://arxiv.org/abs/2208.07794v3 :

> Abstract: Contextuality is a hallmark feature of the quantum theory that captures its incompatibility with any noncontextual hidden-variable model. The Greenberger--Horne--Zeilinger (GHZ)-type paradoxes are proofs of contextuality that reveal this incompatibility with deterministic logical arguments. However, the GHZ-type paradox whose events can be included in the fewest contexts and which brings the strongest nonclassicality remains elusive. Here, we derive a GHZ-type paradox with a context-cover number of three and show this number saturates the lower bound posed by quantum theory. We demonstrate the paradox with a time-domain fiber optical platform and recover the quantum prediction in a 37-dimensional setup based on high-speed modulation, convolution, and homodyne detection of time-multiplexed pulsed coherent light. By proposing and studying a strong form of contextuality in high-dimensional Hilbert space, our results pave the way for the exploration of exotic quantum correlations with time-multiplexed optical systems.

Ultra-fast picosecond real-time observation of optical quantum entanglement

"Real-time observation of picosecond-timescale optical quantum entanglement towards ultrafast quantum information processing" (2025) https://www.nature.com/articles/s41566-024-01589-7 .. https://arxiv.org/abs/2403.07357v1 (2024) :

> Abstract: Entanglement is a fundamental resource for various optical quantum information processing (QIP) applications. To achieve high-speed QIP systems, entanglement should be encoded in short wavepackets. Here we report the real-time observation of ultrafast optical Einstein–Podolsky–Rosen correlation at a picosecond timescale in a continuous-wave system. Optical phase-sensitive amplification using a 6-THz-bandwidth waveguide-based optical parametric amplifier enhances the effective efficiency of 70-GHz-bandwidth homodyne detectors, mainly used in 5G telecommunication, enabling its use in real-time quantum state measurement. Although power measurement using frequency scanning, such as an optical spectrum analyser, is not performed in real time, our observation is demonstrated through the real-time amplitude measurement and can be directly used in QIP applications. The observed Einstein–Podolsky–Rosen states show quantum correlation of 4.5 dB below the shot-noise level encoded in wavepackets with 40 ps period, equivalent to 25 GHz repetition—103 times faster than previous entanglement observation in continuous-wave systems. The quantum correlation of 4.5 dB is already sufficient for several QIP applications, and our system can be readily extended to large-scale entanglement. Moreover, our scheme has high compatibility with optical communication technology such as wavelength-division multiplexing, and femtosecond-timescale observation is also feasible. Our demonstration is a paradigm shift in accelerating accessible quantum correlation—the foundational resource of all quantum applications—from the nanosecond to picosecond timescales, enabling ultrafast optical QIP.

cosmos/iavl is a Merkleized AVL tree.

> The purpose of this data structure is to provide persistent storage for key-value pairs (say to store account balances) such that a deterministic merkle root hash can be computed. The tree is balanced using a variant of the AVL algorithm so all operations are O(log(n)).

Integer Vector clock or Merkle hashes?

Why shouldn't you store account balances in git, for example?

Or, why shouldn't you append to Parquet or Feather and LZ4 for strongly consistent transactional data?

Centralized databases can have Merkle hashes, too;

> Those systems index Parquet. Can they also index Feather IPC, which an application might already have to journal and/or log, and checkpoint?

DLT applications for strong transactional consistency sign and synchronize block messages and transaction messages.

Public blockchains have average transaction times and costs.

Private blockchains also have TPS Transactions Per Second metrics, and unknown degrees of off-site redundancy for consistent storage with or without indexes.

Blockchain#Openness: https://en.wikipedia.org/wiki/Blockchain#Openness :

> An issue in this ongoing debate is whether a private system with verifiers tasked and authorized (permissioned) by a central authority should be considered a blockchain. [46][47][48][49][50] Proponents of permissioned or private chains argue that the term "blockchain" may be applied to any data structure that batches data into time-stamped blocks. These blockchains serve as a distributed version of multiversion concurrency control (MVCC) in databases. [51] Just as MVCC prevents two transactions from concurrently modifying a single object in a database, blockchains prevent two transactions from spending the same single output in a blockchain. [52]

> Opponents say that permissioned systems resemble traditional corporate databases, not supporting decentralized data verification, and that such systems are not hardened against operator tampering and revision. [46][48] Nikolai Hampton of Computerworld said that "many in-house blockchain solutions will be nothing more than cumbersome databases," and "without a clear security model, proprietary blockchains should be eyed with suspicion."

Tapping into the natural aromatic potential of microbial lignin valorization

Transparent wood composite > Delignification process: https://en.wikipedia.org/wiki/Transparent_wood_composite#Del... :

> The production of transparent wood from the delignification process vary study by study. However, the basics behind it are as follows: a wood sample is drenched in heated (80 °C–100 °C) solutions containing sodium chloride, sodium hypochlorite, or sodium hydroxide/sulfite for about 3–12 hours followed by immersion in boiling hydrogen peroxide.[15] Then, the lignin is separated from the cellulose and hemicellulose structure, turning the wood white and allowing the resin penetration to start. Finally, the sample is immersed in a matching resin, usually PMMA, under high temperatures (85 °C) and a vacuum for 12 hours.[15] This process fills the space previously occupied by the lignin and the open wood cellular structure resulting in the final transparent wood composite.

How could transparent wood production methods be sustainably scaled?

"Kernel vs. User-Level Networking: Don't Throw Out the Stack with the Interrupts" (2022) https://dl.acm.org/doi/abs/10.1145/3626780 :

> Abstract: This paper reviews the performance characteristics of network stack processing for communication-heavy server applications. Recent literature often describes kernel-bypass and user-level networking as a silver bullet to attain substantial performance improvements, but without providing a comprehensive understanding of how exactly these improvements come about. We identify and quantify the direct and indirect costs of asynchronous hardware interrupt requests (IRQ) as a major source of overhead. While IRQs and their handling have a substantial impact on the effectiveness of the processor pipeline and thereby the overall processing efficiency, their overhead is difficult to measure directly when serving demanding workloads. This paper presents an indirect methodology to assess IRQ overhead by constructing preliminary approaches to reduce the impact of IRQs. While these approaches are not suitable for general deployment, their corresponding performance observations indirectly confirm the conjecture. Based on these findings, a small modification of a vanilla Linux system is devised that improves the efficiency and performance of traditional kernel-based networking significantly, resulting in up to 45% increased throughput without compromising tail latency. In case of server applications, such as web servers or Memcached, the resulting performance is comparable to using kernel-bypass and user-level networking when using stacks with similar functionality and flexibility.

Show HN: Terraform Provider for Inexpensive Switches

Hi HN,

I’ve been building this provider for (web managed) network switches manufactured by HRUI. These switches often used in SMBs, home labs, and by budget-conscious enthusiasts. Many HRUI switches are also rebranded and sold under various OEM/ODM names (eg. Horaco, XikeStor, keepLiNK, Sodola, etc) making them accessible/popular but often overlooked in the world of infrastructure automation.

The provider is in pre-release, and I’m looking for owners of these switches to test it and share feedback. My goal is to make it easier to automate its config using Terraform/OpenTofu :)

You can use this provider to configure VLANs, port settings, trunk/link aggregation etc.

I built this provider to address the lack of automation tools for budget-friendly hardware. It leverage goquery and has an internal SDK sitting between the Terraform resources and the switch Web UI.

If you have one of these switches, I’d love for you to give it a try and let me know how it works for you!

    Terraform Registry: https://registry.terraform.io/providers/brennoo/hrui
    OpenTofu Provider: https://search.opentofu.org/provider/brennoo/hrui
I’m happy to answer any questions about the provider or the hardware it supports. Feedback, bug reports, and ideas for improvement are more than welcome!

Reversible computing escapes the lab

[+]

How do the efficiency gains compare to speedups from photonic computing, superconductive computing, and maybe fractional Quantum Hall effect at room temperature computing? Given rough or stated production timelines, for how long will investments in reversible computing justify the relative returns?

Also, FWIU from "Quantum knowledge cools computers", if the deleted data is still known, deleting bits can effectively thermally cool, bypassing the Landauer limit of electronic computers? Is that reversible or reversibly-knotted or?

"The thermodynamic meaning of negative entropy" (2011) https://www.nature.com/articles/nature10123 ... https://www.sciencedaily.com/releases/2011/06/110601134300.h... ;

> Abstract: ... Here we show that the standard formulation and implications of Landauer’s principle are no longer valid in the presence of quantum information. Our main result is that the work cost of erasure is determined by the entropy of the system, conditioned on the quantum information an observer has about it. In other words, the more an observer knows about the system, the less it costs to erase it. This result gives a direct thermodynamic significance to conditional entropies, originally introduced in information theory. Furthermore, it provides new bounds on the heat generation of computations: because conditional entropies can become negative in the quantum case, an observer who is strongly correlated with a system may gain work while erasing it, thereby cooling the environment.

> Non-Abelian Anyons, Majorana Fermions are their own anti particles, Topologically protected entanglement

> In some FQHE states, quasiparticles exhibit non-Abelian statistics, meaning that the order in which they are braided affects the final quantum state. This property can be used to perform universal quantum computation

Anyon > Abelian, Non Abelian Anyons, Toffoli (CCNOT gate) https://en.wikipedia.org/wiki/Anyon#Abelian_anyons

Hopefully there's a classical analogue of a quantum delete operation that cools the computer.

There's no resistance for electrons in superconductors, so there's far less waste heat. But - other than recent advances with rhombohedral trilayer graphene and pentalayer graphene (which isn't really "graphene") - superconductivity requires super-chilling which is too expensive and inefficient.

Photons are not subject to the Landauer limit and are faster than electrons.

In the Standard Model of particle physics, Photons are Bosons, and Electrons are Leptons are Fermions.

Electrons behave like fluids in superconductors.

Photons behave like fluids in superfluids (Bose-Einstein condensates) which are more common in space.

And now they're saying there's a particle that only has mass when moving in certain directions; a semi-Dirac fermion: https://en.wikipedia.org/wiki/Semi-Dirac_fermion

Show HN: WASM-powered codespaces for Python notebooks on GitHub

Hi HN!

Last year, we shared marimo [1], an open-source reactive notebook for Python with support for execution through WebAssembly [2].

We wanted to share something new: you can now run marimo and Jupyter notebooks directly from GitHub in a Wasm-powered, codespace-like environment. What makes this powerful is that we mount the GitHub repository's contents as a filesystem in the notebook, making it really easy to share notebooks with data.

All you need to do is prepend 'marimo.app' to any Python notebook on GitHub. Some examples:

- Jupyter Notebook: https://marimo.app/github.com/jakevdp/PythonDataScienceHandb...

- marimo notebook: https://marimo.app/github.com/marimo-team/marimo/blob/07e8d1...

Jupyter notebooks are automatically converted into marimo notebooks using basic static analysis and source code transformations. Our conversion logic assumes the notebook was meant to be run top-down, which is usually but not always true [3]. It can convert many notebooks, but there are still some edge cases.

We implemented the filesystem mount using our own FUSE-like adapter that links the GitHub repository’s contents to the Python filesystem, leveraging Emscripten’s filesystem API. The file tree is loaded on startup to avoid waterfall requests when reading many directories deep, but loading the file contents is lazy. For example, when you write Python that looks like

```python

with open("./data/cars.csv") as f: print(f.read())

# or

import pandas as pd pd.read_csv("./data/cars.csv")

```

behind the scenes, you make a request [4] to https://raw.githubusercontent.com/<org>/<repo>/main/data/car....

> [ FUSE to GitHub FS ]

> Notebooks created from GitHub links have the entire contents of the repository mounted into the notebook's filesystem. This lets you work with files using regular Python file I/O!

Could BusyBox sh compiled to WASM (maybe on emscripten-forge) work with files on this same filesystem?

[+]

Systemd, k8s, Helm, and Terraform model service dependencies.

Quadlet is the podman recommended way to do podman with systemd instead of k8s.

Podman supports kubes of containers and pods of containers;

  man podman-container
  man podman-generate-kube
  man podman-kube
  man podman-pod
`podman generate kube` generates YAML for `podman kube play` and for k8s `kubectl`.

Podman Desktop can create a local k8s (kubernetes) cluster with any of kind, minikube, or openshift local. k3d and rancher also support creating one-node k8s clusters with minimal RAM requirements for cluster services.

kubectl is the utility for interacting with k8s clusters.

k8s Ingress API configures DNS and Load Balancing (and SSL certs) for the configured pods of containers.

E.g. Traefik and Caddy can also configure the load balancer web server(s) and request or generate certs given access to a docker socket to read the labels on the running containers to determine which DNS domains point to which containers.

Container labels can be specified in the Dockerfile/Containerfile, and/or a docker-compose.yml/compose.yml, and/or in k8s yaml.

Compose supports specifying a number of servers; `docker compose up web=3`.

Terraform makes consistent.

Compose does not support rolling or red/green deployment strategies. Does compose support HA high-availability deployments? If not, justify investing in a compose yaml based setup instead of k8s yaml.

Quadlet is the way to do podman containers without k8s; with just systemd for now.

Ask HN: How can I learn to better command people's attention when speaking?

I've noticed over the years that whenever I'm in group conversations in a social setting, people in general don't pay too much attention to what I say. For example, let's say the group is talking about travel and someone says something I find relatable e.g. someone mentions a place I've been to and really liked. When I try to contribute to the conversation, people just don't seem interested, and typically the conversation moves on as if I hadn't said anything. If I try to speak for a longer time (continuing with the travel example, let's say I try to talk about a particular attraction I enjoyed visiting at that location), I'm usually interrupted, and the focus shifts to whoever interrupted me.

This has happened (and still happens often) a lot, in different social circles, with people of diverse backgrounds. So, I figure it's not that I hang out with rude people, the problem must be me. I think the saddest part of all this is that even my wife's attention drifts off most of the time I try to talk to her.

I know it's not a language barrier issue, and I know for sure I enunciate my words well. I wonder though if the issue may be that I have a weak voice, or just an overall weak presence/body language. How can that be improved, if that's the case?

Could building rapport help?

Show HN: TabPFN v2 – A SOTA foundation model for small tabular data

I am excited to announce the release of TabPFN v2, a tabular foundation model that delivers state-of-the-art predictions on small datasets in just 2.8 seconds for classification and 4.8 seconds for regression compared to strong baselines tuned for 4 hours. Published in Nature, this model outperforms traditional methods on datasets with up to 10,000 samples and 500 features.

The model is available under an open license: a derivative of the Apache 2 license with a single modification, adding an enhanced attribution requirement inspired by the Llama 3 license: https://github.com/PriorLabs/tabpfn. You can also try it via API: https://github.com/PriorLabs/tabpfn-client

TabPFN v2 is trained on 130 million synthetic tabular prediction datasets to perform in-context learning and output a predictive distribution for the test data points. Each dataset acts as one meta-datapoint to train the TabPFN weights with SGD. As a foundation model, TabPFN allows for fine-tuning, density estimation and data generation.

Compared to TabPFN v1, v2 now natively supports categorical features and missing values. TabPFN v2 performs just as well on datasets with or without these. It also handles outliers and uninformative features naturally, problems that often throw off standard neural nets.

TabPFN v2 performs as well with half the data as the next best baseline (CatBoost) with all the data.

We also compared TabPFN to the SOTA AutoML system AutoGluon 1.0. Standard TabPFN already outperforms AutoGluon on classification and ties on regression, but ensembling multiple TabPFNs in TabPFN v2 (PHE) is even better.

There are some limitations: TabPFN v2 is very fast to train and does not require hyperparameter tuning, but inference is slow. The model is also only designed for datasets up to 10k data points and 500 features. While it may perform well on larger datasets, it hasn't been our focus.

We're actively working on removing these limitations and intend to release new versions of TabPFN that can handle larger datasets, have faster inference and perform in additional predictive settings such as time-series and recommender systems.

We would love for you to try out TabPFN v2 and give us your feedback!

Tell HN: ChatGPT can't show you a 5.25" floppy disk

Challenge: Come up with a query that makes it draw something resembling a 5.25" floppy, that is, without the metal shield and hub that is present on the 3.5" disks.

What about LaserDisc and CD-ROM?

German power prices turn negative amid expansion in renewables

Given the intraday prices, are there sufficient incentives to stimulate creation of energy storage businesses to sell the excess electricity back a couple hours or days later?

Or have the wasteful idiot cryptoasset miners been regulated out of existence such that there is no longer a buyer of last resort for excess rationally-subsidized clean energy?

Are the Duck Curve and Alligator curve problems the same in EU and other energy markets with and without intraday electricity prices?

Duck curve: Solar peaks around noon, but energy usage peaks around the evening commute and dinner; https://en.wikipedia.org/wiki/Duck_curve

Alligator curve: Wind peaks in the middle of the night;

> So, if we’re not duck-like, what is the Upper Midwest’s energy mascot? We give you: the Smilin’ Gator Curve. Unlike California’s ominous, faceless duck, Sally Gator welcomes the Midwest’s commitment to renewable generation!

(An excellent drawing of a cartoon municipally-bonded incumbent energy utility mascot!)

Can cryptoasset or data mining firms scale to increase demand for electricity when energy prices low or below zero? What are there relocation costs?

Is such a low subsidized energy price lucrative to energy storage, not-yet-PQ Proof-of-Work, and other data mining firms?

Can't GPE gravitational potential energy in old but secured mine shafts scale to meet energy storage requirements?

So, per your understanding, grid connectivity for energy production projects is a bigger issue than energy storage in their market?

Price falls below zero because there's a supply glut (and due to aggressive, excessive, or effective subsidies to accelerate our team transition to clean energy).

Is it the national or regional electricity prices that are falling below zero?

Is the price lower during certain hours of the day? If so, then energy storage could probably smooth that out.
