When I was running a block explorer for ETC I’ve got such requests to provide logs on who accessed certain address. Proper requests, with signatures and rubber stamp. I guess everyone receives them periodically

fascinating. feds used the IP addresses of etherscan email notifications to locate an ethereum node operator in the southern district of new york to satisfy a venue requirement to prosecute someone else

Since when @x prevents new accounts from using a combination of commons words? I tried a couple of dozen combinations, everything "is already taken" though I see no evidence those ever existed. Misspelling or a random number fixes that.

Received a deactivation warning from @OpenAI after I asked it to find a few XPubs published online. Need them for some demo of @getemerald But they think it's a cybersecurity concern. Which is obviously wrong, but now I'm wondering how long before the web is effectively censored by AI?

Like:
> You asked me to find history of event Y? Okay, checking... Oh, someone who owns us is in a bad light here. That violates our terms - banned!

Wanted to rent a couple of new servers. The price for memory alone is ~$1300/mo for 512GB. I guess we're not getting any new servers for a while.

Saw today how they prepare to sell a penthouse. They put a huge light projector on the balcony, big enough to summon Batman, directed up to a reflector on the top corner outside the main window. Dark, rainy, very London outside. But bright, warm and cozy inside for the photos for the sales

I actually didn’t know about this. Thought I can just use ND filters from camera. But turns out it’s different wavelengths or so and it’s even more dangerous to use ND filters and similar

[Aleksey Shipilëv @shipilev]

PSA: Under NO circumstances look at the Sun without proper Solar-grade filters. NOT with the naked eyes, NOT with sunglasses, and especially NOT with any lens optics. NOT EVEN WHEN SUN IS AT TOTAL ECLIPSE! You WILL damage your retina, even if temporarily. Warn others near you.

That's not true. You closed my account without a reason. Only because I applied to a business account, which got declined, and immediately closed my personal account, at the same time. I.e., it's not because I did something with my personal account, I didn't touch it, so that makes it pure "no reason."

Rewriting my Blockchain API load balancer from JVM to Rust, and I really like how well Claude handles it.

When you ask it to rewrite code, you already have a very detailed spec as the code. It says exactly how things actually work, with unit tests to verify. Yes, it still makes silly mistakes, but you just point it at the legacy piece to show how it's supposed to work.

I still review it and I don't think a vibe rewrite to Rust would produce a good result.

The only hard part is translating from one paradigm to another, and Fable handles even that. It goes into the details, gets why, and how to write it with a completely different design. It's amazing.

[Igor Artamonov @splix]

For people like me: imagine two dots, Red and Blue, on a screen connected by a formula that uses only simple math. Just +, -, and *, nothing else.

If you push Red in any direction, Blue also moves, just in some different direction. But always moves. So you'd assume you can in theory deduce Red's position from Blue. Because the math operators are straightforward with no loops, etc. Must be reversible, right?

Basically, you'd assume all combinations are unique.

That was just an assumption. Seems logical! But no one could prove it.

And now there's a function below that produces the same Blue coords for different Red inputs. So this one is not reversible, meaning the whole assumption was wrong apparently.

I don't know what the implications are, but it's interesting

hello there the jacobian conjecture is false thanx to my close friend akhil for asking about it and my other close friend fable for working during the world cup final

((1+xy)^3 z + y^2 (1+xy) (4+3xy), y + 3 x (1+xy)^2 z + 3 x y^2 (4+3xy), 2 x - 3 x^2 y - x^3 z): \C^3\to \C^3, has jacobian determinant -2, and sends (0, 0, -1/4), (1, -3/2, 13/2), and (-1, 3/2, 13/2) to (-1/4, 0, 0)

It's surprising that X is discouraging reporting bad posts by showing the "please upgrade" window afterward. I'm not doing that. Why? How it's even related to the scam links in the posts I've just reported?

Years ago I installed OpenLens to manage Kubernetes clusters, and recently realized it doesn't get updates anymore because the commercial version closed their sources. Okay, fine, I'd better use the commercial version even though they charge more than most other dev tools, but I guess it's worth it? Turns out it's not, b/c the new version is bloated with AI, virus checks and other bullshit which makes every click to take a second to render, cluster changes aren't refreshed automatically, etc. The core functionality is unusable in favor of fancy stuff. That's what I call going full ACDSee mode.

Hi @Cloudflare, it would be helpful if you signed the cf-* headers so we can trust them and reject requests if someone managed to connect to our endpoint directly. What do you think?

[Igor Artamonov @splix]

I like reading https://t.co/kjoqlnDGCF because I'm interested in how a modern city grows, architecture-wise. It covers NYC, but I wish a similar blog existed for Miami and London. I've lived in all three, and I think they have very unique cultures and their own architecture styles.

@hishboy An alternative to docker sandboxes? https://t.co/A6ZJleSozI

Hi @gemini. You ceased your UK branch this year, which is understandable. But you also invalidated the API keys for your ex-customers and don't allow creation of new ones. That creates a huge problem as we can't download trade history for accounting and taxes. Can you enable the API back?

@paulg There should be a skill for writing emails, that tells just one thing “keep it short”

It's hard to be a Security Researcher. In one hand there are businesses that ignore their legit submissions, and don't pay bounties. And on the other hand there are those bounty hunters that just diminishes all their work by bombarding businesses with tons of "Critical Security Vulnerability Found" on their S3 hosted landing page that "demands immediate attention"

[Igor Artamonov @splix]

So we’re all switching to local DeepSeek v5 Pro?

[Anthropic @AnthropicAI]

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.

The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.

Access to all other Claude models is not affected.

We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

Just learned about "bind mounts" in Docker. Ex., when you use Docker for building from sources, instead of ADD or COPY your code into the image it's much faster to just bind the directory. Also unlike Volumes it's not restricted to the current dir, so it works for path deps as well
