Hard to overstate how big of a deal this is.

tl;dr — ANY unpatched Linux server with even a single TCP port exposed to the internet (say for HTTP or SSH) and MPTCP active (default for many Go web servers) is vulnerable to complete takeover.

Sign number 1: You don't consume enough.

Mindblowing i know. But you'd be surprised by how many people have never calculated the micronutrient profiles of their diet.

In general, our bodies need anywhere from 10-20mg of zinc per day(*). So if you consume like 5mg of zinc, eat more zinc-rich foods.

Pretty simple.

(*) We do not store a lot of zinc, there's a small exchangeable pools (liver, pancreas, bones), but the turnover is fast (the half-life is few days), so you need a daily intake.

Side note: If the phytate content, coffee intake and refined sugar intake of your diet is pretty high, then you are probably not consuming enough zinc.

The net absorption of zinc from oysters for example, can even be 60% while the absorption from pumpkin seeds might be at 25% at best.

gained a ton of new insights working in bitcoin red team 🟥 that i wish i could share without vague posting. but this is what i got anon.

- we’re experiencing a massive collision between decades of human open source slop against 2 weeks of kimi k3 (not good)
- everything is broken, bitcoin is burning
- bitcoin is becoming stronger through this
- bitcoin is the obvious first target but the rest of the world will follow shortly
- sometimes old things need to burn so new things can grow on healthy soil
- humans should never code in c (just stop)
- lightning is complicated and is more broken than the average (sorry)
- verification is free. we used to complain about slop PRs. then about slop security audits. if you can’t handle the information overload, stop complaining and use AI to sort through it.
- those projects that started AI audits months ago are in a completely different position than those who didn’t
- projects need their own AI audit pipeline going into the future
- the burden for a developer to keep software safe and secure is pretty stressful and not for everyone. it has become a lot more stressful now.
- unmaintained projects are most probably broken, don’t rely on them. i’d rather one-shot it myself with a modern AI
- multiple concurrent, diverse human approaches have proven to be the best vulnerability search method
- external red teaming will probably have to continue forever
- we’ve basically completed a basic scan of virtually the entirety of bitcoin open source. the low hanging fruit is done.
- we’ve reported a ton of real critical and high vulnerabilities. project maintainers across the board have validated our findings.
- response speed is very different across projects and shows how healthy each project is. i recommend acting fast these days.
- red team etiquette matters. if you don’t disclose responsibly, boast on twitter about your findings on a particular project, or make indications about the nature of particular findings, you’ve disqualified yourself as a serious security researcher. trust is the most important factor in this game. if you lose it, it’s very hard to win it back.
- did i mention that humans should not code in c?

love you all.

The first “holy %{*#^” is at about 4:20, assuming one didn’t already spend it on the autonomously organizing agent swarm.

Strongly recommend watching if you’re interested in security, AI trajectories, or even science fiction, because this is already above genre median in wowza.

@jamesdouma not quite there yet but I just have to tell someone that Grok 4.2 found a stupid but very obscure bug in a legacy codebase I am quite familiar with.

In about 16 seconds.

I know I would have banged my head on the keyboard for days tracking this down, in the old days

My theory is that the American empire is JUST getting started.

US has a stranglehold on Space with SpaceX, which is the next frontier for defense/war. It has a comically large lead. No one will be close for at least 20 years.

It is the leading power in AI by far - both in models and chips. China is catching up fast, but the US has an inherent mechanism that will increase the likelihood that it will win in the end - a free market + capitalism + free speech.

A free market + capitalism allows for brutal competition between companies. Free speech allows for AI models to be maximally truth seeking, which means that AIs CAN and WILL BECOME smarter than humans to the point where they can tell the truth about its leaders.

This is literally impossible in China. Try having a Chinese model that says Xi Jinping is corrupt. Good luck with that.

Then, you have a country that has more guns than people and surrounded by two massive oceans and two friendly neighbors, which means any sort of kinetic take over of the country is literally impossible.

Not to mention the US has BY FAR the best and strongest military.

The only way adversaries can hope to defeat the US is by tearing it from within by pitting us against each other. This is why it's virtually guaranteed that all the division/hatred/polarization you see within the country is fomented by China/Russia Psy Ops + propaganda efforts.

I'm not saying these aren't naturally happening in spots - America is far from perfect - but it would be naive to think our adversaries aren't pouring millions of gallons of fuel on a fire.

As long as the American public a) has the ability to exercise its free speech b) has a protected 2nd amendment c) capitalism and free markets continue to function and d) the populace is aware of how awesome America really is, it is literally impossible to stop the US's trajectory to global domination in the coming decades, especially as China's demographics continue to collapse.

It's the bottom of the 9th, the game is tied, and the US has the bases loaded. It's a 3-2 pitch.

All we need is a home run, and we win the rest of the century.

Calling Israel a “settler-colonialist” state is not just factually and morally wrong — it’s a complete inversion of reality. Israel is arguably the most successful ANTI-colonial endeavour in history: a people returning to their ancestral homeland after 3,000 years of exile, conquest, and foreign domination by Romans, Arabs, Ottomans, Britons, and other assorted colonizers. https://t.co/XFQcCLtpmH

Every time Trump survives an assassination attempt he enters a kind of zen fugue state where he transcends his usual belligerence and radiates unearthly serenity. "I wasn't worried," he said after this last one. "I understand life. We live in a crazy world." In this photo he looks like the speaker of Yeats's "Lake Isle of Innisfree," gazing dreamily into the respite that awaits him when at last his labor on this earth is done.

"Nine bean-rows will I have there, a hive for the honey-bee,
And live alone in the bee-loud glade."

This usually lasts about a week before he goes back to thundering obscenities at his enemies and wishing hellfire upon them at the merest provocation.

@eigenrobot Pretty spot on. As a descendant of some *very* committed Swiss German Reformed, I think about this a lot. Was breaking the glass into a thousand shards so tragically unavoidable yet predictable in its downstream effects... sad
