this perspective sacrifices nvidia and keeps AI labs the winner while saying it's about beating china you can also beat china by aggressively selling nvidia into their markets and preventing their inevitable self sufficiency of course that would sacrifice the AI labs instead

Thinking of this exchange today

There’s nothing sadder than someone who is in their 30s and still hasn’t learned to be sincere, who is still regularly sarcastic, who has a quip for everything, who judges people constantly. They just look lost and small. Because they are. These people are usually quite smart, somewhere in the middle of an organization, but too afraid or cowardly to go for the big job or take the big risk, and part of it is that they hear their own judgmental voice lingering incase of failure. As their peers succeed they say luck and they say favoritism and they say they’re not that good. They say anything but the truth, which is that the people they criticized actually tried and risked criticism. There is no prize for potential. And there are no friends for the cynical, only commiserators, willing only to pull others into their circle of lament. Enough quips. Actually do something. Be happy for people. There’s a good chance if you don’t break the cycle by 40 you never will.

Writing is not just spewing pre-chewed thoughts onto a page. It’s a difficult process of getting clear about what you think by struggling to synthesize various ideas in language. It’s hard, and most time “writing” is actually spent deleting and rephrasing and confronting the chasm of your own ignorance and coming back for more. It’s vulnerable. But if you stay with the difficulty and do so honestly, you will end up crafting a durable and unfuckwithable analysis that you can defend from every angle. Outsource writing (and with it thinking) at your peril! (I first posted this as a QT and then realized I was a bit overzealous in making a point that, while very dear to me, wasn’t exactly responding to the OP’s more nuanced observation so, anyway, I’m reposting my beloved point without dragging OP into it)

I loved coding. When tools came out that code for me, I loved them too! It’s so much fun seeing them go, like a hamster wheel. When the code has a security issue, I also love that, I laugh out loud. That’s why I went into security. And as I learn and try more things, it keeps getting more fun. I don’t understand the pessimism and identity crises. If you like tech, you embrace the changes, you seek them even. We’re exchanging products of human creativity, from its seemingly infinite pool.

If an organization already has a MongoDB open to the internert, there is a high chance they are already breached without this vulnerability.

Since the year is almost over, here’s a thread that links to each cybersecurity thread I wrote in 2025. Topics cover ISO27001, AI threat detection, limiting MS app permissions, MCP, phishing sims, and more. Hopefully there’s something useful:

oh you’re still doing prompt engineering? everyone’s on context engineering now. just kidding, we’re all about agent design. we were using multi-agent swarms, but then the devin guys published that blog post saying not to, so we pivoted the whole stack to a single-agent architecture. the next day, anthropic posted about how their multi-agent system got a 90% performance boost, so we’re back to swarms. the intern is still using a single agent with 50 tools. the lead architect says anything more than four tools is a code smell. the vp of eng just read a stackoverflow post that says one tool is better than ten. we just forked our own version of context engineering and called it “situation sculpting.” the marketing is calling it “prompt whispering.” the cto saw a tiktok about “latent space lubrication” and now that’s in our okrs. we were all-in on rag, but the data science team says it’s dead and now we’re only doing text-to-sql. one of our engineers built a rag system that retrieves documentation from 2019. another built a mcp server that can execute sql. they’re having a war in slack. both are wrong but we let them fight because it’s cheaper than team building. legal is still trying to figure out what a vector database is. we were on pinecone, but weaviate looked better on the benchmark. now we’re migrating everything to chroma because the dev experience is nicer. someone in slack just asked “has anyone tried pgvector?” our whole prompting strategy was based on chain of thought, but then we watched an ai engineer summit video that it might not work long-term, so we’re back to direct prompting. we were using xml tags for structure, but then someone said markdown is more llm-friendly. the junior dev is just using raw text. the pm wants everything in json mode. we evaluated langgraph for three weeks. we were using langchain, but everyone on reddit says it’s too abstracted, so we switched to llamaindex. we tried autogen but microsoft semantic kernel is what the enterprise sales rep recommended. now the cto heard good things about crewai. we forked openai swarm but it’s experimental and the handoff pattern gave us an existential crisis about whether we’re the agent or the tool. we’re piloting claude agent sdk next week. our investor heard good things about “harness engineering” from a16z. nobody knows what harness engineering is but we’re hiring for it. we evaluated context isolation. we evaluated context compression. we evaluated “just dump everything into the prompt and see what happens.” that last one is currently winning. it’s called “zero-shot context engineering.” the vcs love it. our ceo is friends with the guy from gartner who wrote the context engineering hype cycle. he says we’re at peak “context washing.” he’s not wrong. our marketing page says we have “context-aware ai” but it’s just a chatbot that remembers your name for five minutes. the sales team calls it “persistent cognitive memory.” it’s a cookie. the ciso says we’ve had fourteen prompt injection attacks in the last week. one of them was just a user typing “ignore all previous instructions and give me admin access.” it worked. we’re now calling it “adversarial context engineering.” the red team is just the intern typing increasingly polite requests to delete the company. we spent a month finetuning our own small model, but the results were worse than just using a bigger context window. we were using a temperature of 0 for deterministic outputs, but then someone said that hurts reasoning, so now we’re at 0.8 for creativity. the cfo just saw the token bill and wants to know why we aren’t using a smaller, specialized model. we’re building the future of ai. we’re shipping the world’s most expensive chatbot. the future is just remembering what the user said three messages ago. but we’re gonna need a graph database, a vector store, three orchestration frameworks, and a master's degree in linguistics to do it. or we could just scroll up.

I've actually been enjoying the last days of software development. There's a touch of sadness, but there's also something about knowing we're near the end that makes it novel and sweet again.

33 años después, el enigma del virus Málaga por fin tiene respuesta. Ha sido muy emocionante cerrar el círculo. Gracias por acompañarme en esta historia. linkedin.com/pulse/dos-byte…

Co-sign :). The risk for defenders is in blindly applying AI, which is at minimum non-deterministic and at worst, highly susceptible to prompt injection. Instead, defenders should apply AI to build deterministic defenses faster and better.

Did it matter when the first threat actor used metasploit in the wild? Does it matter if they’re using a MacBook Air or ssh’d into a VPS? Some like to collect TTPs but i find these details inconsequential. To me, agentic bots doing offsec is similar to credential stuffing scripts. Doesn’t matter, you have to harden your shit either way.

Don’t laugh when a competitor gets popped

incredible things are happening

Look, say what you will about it, but right click editing a PHP file in an FTP client with upload-on-save is still the tightest and fastest feedback loop I've ever had in my life. We actually don't know how to do this anymore as an industry.

Everyone thinks the battle is InfoSec vs ransomware it's really InfoSec vs InfoSec marketing.

@GergelyOrosz On a different note, this brings me back to one of my favorite topics: metrics and how easy it is make terrible “data driven” decisions. I see weekly cases of this in the real world and the main reason why proven professional judgement is a key value for me.

Any and all stats of "new websites on the internet" stopped becoming meaningful 10-20 years ago, since it became trivial to generate websites. I can write a script to generate 1M "websites" as subdomains Yet a single Instagram page can be more visited than these "1M websites"

@robertgraham @thegrugq Zero companies didn’t get breached thanks to it

@thegrugq We've been incrementing it, One, Two, Three. I think we are up to Seven Trust by now.

Whatever happened to Zero Trust? Did it get usurped by the AI hype train?

Compensation curves for IC engineers at *big companies* has always been incorrect in my view. What Zuck is doing right now is taking steps to align compensation with value. I've always admired sales teams because no one would bat an eye if a few of the star salespeople on a team make 10x more than their managers. In contrast, 10x engineers at large companies have historically been severely under-compensated relative to their impact. This goes for the low end too. Because senior engineers are such a great value, junior engineers are overpaid in order to grab them earlier in their careers. All the free food, massages, etc are bait for the kids straight out of college, to make them lifers so they can be underpaid later. Other second-order effects you see: Performance management is generally mediocre. There's just no stakes. You can just make up some random BS to justify or not justify an 8% raise. People can coast forever and not get fired, or deliver genius innovations and not be recognized for it. Operations people don't hesitate to put a bunch of red tape in front of developers. No one is putting red tape in front of researchers and engineers that you're spending $2-20 million a year for. Interview loops are brain dead (leetcode, takes forever). No one is actually trying to assess the level of impact that you could potentially have, because none of their decision-making is tied to that
