SwtCyber··on Early rogue AI agent activity and attempts to hack found on urlquery.net
If this were a staged showcase of model capabilities they would have picked a more impressive target than a regional university digital library
SwtCyber··on Early rogue AI agent activity and attempts to hack found on urlquery.net
Testing model capability boundaries is necessary, but a solid network sandbox for these evaluations takes a couple of hours to set up with standard infrastructure tools. No engineering team evaluates unverified systems against live third-party infrastructure without coordinating with the owners

Evaluating edge cases and network behaviors belongs in isolated staging environments with local database mirrors. Letting an agent hit the public web and probe government domains is simply poor hygiene in test environment setup

SwtCyber··on Principles for Fast Tokio Applications
Give a task ownership of some state, communicate through channels and suddenly a lot of locking just disappears from the design
SwtCyber··on Principles for Fast Tokio Applications
I think channels deserve more emphasis here too, especially because they change the architecture rather than just swapping synchronization primitives
SwtCyber··on Principles for Fast Tokio Applications
One thing I appreciate here is treating scheduler fairness as something you spend, not something you get for free
SwtCyber··on Music Theory for Programmers
For a programmer, deriving intervals and chords and then hearing the code produce them is a pretty effective bridge
SwtCyber··on Music Theory for Programmers
I don't think the article needs to get you all the way from A to S to be useful. A Fourier transform doesn't tell you why a song is good either, but understanding harmonics can still improve your mental model of sound. Same with temperament, intervals or why a keyboard is laid out the way it is.
SwtCyber··on Music Theory for Programmers
Yeah, this is the advice I wish showed up more often in "learn music theory" discussions
SwtCyber··on Music Theory for Programmers
I think there's still a pedagogical niche for what the article is doing. For someone coming from programming, "here's why these conventions aren't completely arbitrary" can be the thing that gets them interested enough to later learn harmony properly
SwtCyber··on Music Theory for Programmers
I like this less as "music theory from first principles" and more as "why some of the machinery of Western music looks the way it does"
SwtCyber··on AI Can Make You Suck Faster Too
There’s a night-and-day difference between frontier and budget models, no question. But the issue isn't the tooling at all : if you put someone who doesn't know the rules of the road on a $15k carbon road bike, they're just gonna slam into a telephone pole at 30 mph instead of 6 mph
SwtCyber··on AI Can Make You Suck Faster Too
Just let him take down prod on a friday night once and leave him to deal with the PagerDuty alerts solo. Cures the urge to vibe-code infrastructure real fast
SwtCyber··on It takes 5 cloud services to hear my doorbell
Two wires and two C cells? Careful, someone is going to put a subscription layer in front of that
SwtCyber··on It takes 5 cloud services to hear my doorbell
Every individual product is "easy", but the moment you want two ecosystems to talk to each other you become a part-time distributed systems engineer
SwtCyber··on Judge rules Trump administration’s blacklisting of Anthropic was illegal
Truly a flawless strategy: convince every government and large company on earth that depending on US-hosted AI is a geopolitical risk.
SwtCyber··on Judge rules Trump administration’s blacklisting of Anthropic was illegal
The harder problem is designing remedies that make illegal government action actually expensive enough to discourage it, without also making officials afraid to make legitimate decisions.
SwtCyber··on Meta's blockbuster trial draws parallels to big tobacco
Yeah, the internal research could be far more damaging than the existence of the harmful effects themselves
SwtCyber··on Meta's blockbuster trial draws parallels to big tobacco
The distinction between punishment and prevention seems important here. Meta's intent might matter when deciding liability or penalties, but if a design pattern is demonstrably harmful, "we only wanted more engagement" isn't much of an argument against regulating it
SwtCyber··on Meta's blockbuster trial draws parallels to big tobacco
That's fair. A lot of regulation seems to work this way: first you recognize a real harm, then spend years arguing over where exactly the boundary should be
SwtCyber··on Meta's blockbuster trial draws parallels to big tobacco
Investors not panicking seems rational. Companies this large can survive astonishingly large fines...
SwtCyber··on Show HN: Doberman: The AI watchdog that stops Claude from deleting your database
Give the agent a read-only postgres user. Boom, I just saved you a startup
SwtCyber··on Anthropic becomes the 'Apple of AI': Most revenue despite being most expensive
Architecture is secondary right now. How Anthropic cleaned up the datasets for training and tuned the alignment - that's the real engineering magic. OpenAI came up with GPT, but Anthropic turned it into a fully functional tool for engineers
SwtCyber··on Anthropic becomes the 'Apple of AI': Most revenue despite being most expensive
Journalists just took whichever numbers fit the Apple narrative better
SwtCyber··on Anthropic becomes the 'Apple of AI': Most revenue despite being most expensive
Vercel data as proof of market dominance is hilarious. Obviously next.js pet projects are mostly generated by Claude, it's just unmatched for frontend right now. But enterprise with their rag pipelines is sitting on Azure with OpenAI, and there are completely different budgets spinning there that simply don't make it into any Vercel dashboards
SwtCyber··on Low-Tech Ceramic Water Filter
Maybe, although I think cement would trade one set of manufacturing problems for another
SwtCyber··on Low-Tech Ceramic Water Filter
The passive cooling is almost as clever as the filtration
SwtCyber··on Low-Tech Ceramic Water Filter
There is something very satisfying about sawdust being a feature rather than an impurity
SwtCyber··on As AI eats the web, the internet’s collective memory is disappearing
Disney killing the FiveThirtyEight archives is just basic s3 cost optimization, not `ai devouring humanity's memory`. A dead site just doesn't run ads
SwtCyber··on How I use LLMs to learn complex topics
The "100% accurate and free of hallucinations" claim should probably be replaced with something much weaker
SwtCyber··on How I use LLMs to learn complex topics
I think there's an underrated difference between information generation and pedagogy here. LLMs are very good at producing more explanation, yet "more explanation" is often exactly what you don't need when learning something difficult
