We introduce the Hidden Number Problem with Chosen Errors (HNP-CE), a variant of the linear hidden number problem where the exact noise terms (βi) are unknown but shared across different relations with known weights(w).

Taken verbatim "Maybe you've heard about the little app called OpenClaw. OpenClaw is powered by pi. That made me collateral of Peter's success. Especially after Armin thought it's a good idea to tell the whole world about the relationship between OpenClaw and pi on his blog."

It's so bizarre how OP was downvoted. It's a truth. History repeats itself. It's not the first war. It's not the last war. Maybe his (or her) tirade on capitalism annoyed the HN downvoting shoggoth.

Does Stripe use Railway? The dashboard was down today and this is the only incident report I've encountered and the timeline matches Stripe's downtime.

It's super nit-picky of me to point out: the double and add visualization is a meme among professional elliptic curve guys.

You are in fact drawing a hyperbola between points on an (almost) circular plane. However, you won't find this published anywhere idk why. It's just one of those things you get from spending 3 years in office hours with the 73 year old math professor who's worked on elliptic curves since they became mainstream in the 1980's.

My PhD advisor demanded I use Julia for my dissertation. Back then I was a junior programmer so Julia's one-based indexing absolutely threw me off.

In retrospect, the PhD experience was miserable and using Julia contributed to my 'death by a thousand cuts'.

The hidden number problem (HNP) is the challenge of recovering a secret hidden number given partial knowledge of its linear relations. The extended hidden number problem is 'the HNP but with more holes'. It was thought to be more secure for quantum cryptography. Turns out, it's not lol.

The paper, Guessing Bits: Improved Lattice Attacks on(EC)DSA with Nonce Leakage , improves on the (Albrecht & Heninger, 2020) lattice-based HNP attack by:

    Guessing some secret key bits to increase attack success probability.

    Decomposing the secret key into batches to recover parts of the secret. ie. it’s no longer an ‘all-or-nothing’ approac

I ran a moderately large opensource service and my chronic back pain was cured the day I stopped maintaining the project.

Working for free is not fun. Having a paid offering with a free community version is not fun. Ultimately, dealing with people who don't pay for your product is not fun. I learnt this the hard way and I guess the MinIO team learnt this as well.

1. I like my laptops with USB ports and removable RAM and disk. I love computers and opening up a mac is a bad experience.

2. It costs an arm and a leg to replace parts on a Mac when you travel outside the United States. Replacing the keyboard on my first macbook cost the same as the actual price. I learnt my lesson. I don't need that Apple garbage in my life.

Exactly my predicament. My laptop reached EOL but I'm struggling to purchase a new one.

They're all bundled with AI features (I absolutely don't need) and never in my life will I buy a mac for coding. My current laptop is HODL'ing and idk if this enshittification will end soon.

The 2001 paper Hardness of Computing the Most Significant Bits of Secret Keys in Diffie-Hellman and Related Schemes (Boneh & Venkatesan, 2001) attempts to answer the question: is it easier to calculate just a few bits of a secret key than the entire secret?

Along the way, this paper introduces the hidden number problem: the challenge of recovering a secret hidden number given partial knowledge of its linear relations (Surin & Cohney, 2023)

As it turns out, this problem is difficult even for quantum computers. So hidden number problems are at the heart of post-quantum cryptography.

Sudoku solvers are great for testing reasoning models. The paper 'Sinkhorn Solves Sudoku' showcases Belief Propagation, an alternative to backpropagation rooted in Optimal Transport theory.

The idea is somewhat analogous to performing a softmax but without the derivatives. It's pretty cool IMO.

Out of curiosity, do you offer visa sponsorship? I'm graduating from a US university this Fall with a Stats/CS degree, but I took 2 gap years just to manage my aging father's rental property business in my home country, Kenya.

I'm a software engineer but (thanks to my elderly father) I know the super fine details of rental property management.

For what it's worth, when I started out in 2023, the business was -1.3 million USD in construction debt. In 2025, 2 years into my role and we're at no debt, 34 fully occupied homes and 3 luxury villa sales. I can 100% provide documentation to prove this.

I made a short video guide to using Nvidia's CuCollections library for GPU accelerated data structures.

We setup the official Cuda Collections library for C++ data structures on Google Colab.

The GLV endomorphism is a neat math trick for fast scalar mutliplication on Elliptic curves. Funfact the GLV patent expired in 2020 and finally added to Bitcoin's public repo.
