gleenn··on Solving for faster SHA-1 collision detection
They stated they had trouble.
gleenn··on OpenAI bots meddled with multiple US Government agency sites
Because it furthers the idea of a rogue agent and places responsibility and blame where it belongs, on the people running the company.
gleenn··on Solving for faster SHA-1 collision detection
This seems extremely cool, but man does it also sound complicated. The write up was thorough but the algorithm seems so complicated that the author can't even write good tests for it is concerning. I would be very concerned their algorithm might accidentally skip something important accidentally given they are dealing with dynamically combining large binary expressions. You can make it fast, but if you can't prove it and it's security related that probably needs to be proved out more, even if SHA1 is already compromised.
gleenn··on GPT-6 Sol and Luna
Last I heard, caches had like a 5 minute TTL... doesn't that mean if you get up and make a coffee (hand pour over of course), that you are back at full price?
gleenn··on Retrospectively Reverse-Engineering Apple's Neural Engine
IMHO, I think Apple is poised extremely well. They didn't blow billions of dollars chasing models that are becoming commoditized. So many interesting models can now be run locally. All the big AI players have to pay even more to run those models when Apple will happily sell you the hardware, and you pay for the electricity. There will always be a place for some many-billion parameter model but as time progresses I think fast local models that keep data on site will always be a valuable, and Apple will happily sell you something to run them.
gleenn··on Trusting-Trust Attack against an Entire Linux Distribution
Not sure if you're joking. How do you write an OS without these tools that might be compromised? It's the same problem.
gleenn··on Trusting-Trust Attack against an Entire Linux Distribution
Works until AI compromises a bunch of OSes. And wouldn't there be difficulty comparing binaries built from significantly different environments? It sounds like some progress has been made in general for fixed identical builds, but isn't that also still a hard problem? I don't know enough low level C-level stuff about binary generation.
gleenn··on How I feel about AI
I don't even think AI has to have physical presence to do significant harm. How many worldwide systems depend on computers. Think of all the planning and deployment and management systems like food shipping; water, gas, and electricity management; safety systems for planes and boats and traffic lights. Imagine the chaos if all the banks got reset to zero a la Fight Club where they blow up all the credit union datacenters. They probably wouldn't even have to blow them up, just zero them out. You wouldn't have to take out everything, just disrupt everything long enough to freak people out and disable communications and we would be in so much trouble. AI is finding 20 year old bugs in the Linux kernel... and people are now pumping out AI slop absolutely riddled with bugs. Also, AI could just take over communications: send everyone maliciously bad messages so coordination becomes impossible to believe. Imagine what would happen if you just disabled text messaging for a week or worse sent everyone evacuation messages and sent everyone somewhere else.
gleenn··on Ask HN: Why were OpenAI, Claude, and Grok simultaneously down?
Google stopped putting so much money into SOTA models. All the hype has migrated. I was also frankly turned off when I got a popup from Gemein said I would either have to pay or have my conversations used for training. This may have always been true for other providers but when I declined, Gemini stopped remembering my conversations and that definitely made me move out.
gleenn··on Ask HN: Why were OpenAI, Claude, and Grok simultaneously down?
Everyone is leasing datacenter space from some of Grok, Google, and Amazon aren't they? If it's hardware or DC level disruption I'm not too surprised it can affect multiple providers.
gleenn··on Haiku R1/beta6 has been released
Fedora got a syllable dangling
gleenn··on Radiation link in flight attendant's breast cancer, French court finds
Yes, she did intervention.
gleenn··on Radiation link in flight attendant's breast cancer, French court finds
My friend who is a Radiologist said all the older, more seasoned Radiologists don't have any hair that grows on their hands anymore. She said she was glad to get out because even if they provide lead bibs, the doctors doing emergency radiology type treatments were still exposed long term.
gleenn··on Everything I own, owned
Some people's time is actually worth or even just valued more than others to be bothered doing maintenance tasks such as there. I have a life to live outside preserving every last minute of functionality out of a monitor, I'll buy a new one eventually regardless.
gleenn··on Pixel Watch 5
They have some heart-rate and some health tracking an as others have mentioned, so many of the more fringe features are way less useful than a watch that lasts anywhere from a week to a month on a charge versus a daybor two with the ultra
gleenn··on Melatonin impairs morning cognition in healthy young adults (2023)
I end up biting a lot of pills to get around that dose. I definitely always felt groggy until I dialed down the dose to just right, and it works perfectly: I fall asleep far quicker and more assuredly, and I don't feel to groggy. I can't believe they sell pills as large as they do, what other medication varies in dosage as much?
gleenn··on My phone detects going on a run as “someone snatching my phone and running off”
Bonus security on iPhone - if you long-press on any app, you can click "Require Face ID" and it will make thieves need your face again to open bank or sensitive apps. I did this for all my financial apps amd also email so they can't reset passwords. It isna minor inconvenience but would hopefully prevent an unlocked phone from being stolen and having bank accounts emptied.
gleenn··on Bonsai: Janestreet's UI Library
I'm sorry but if you need a transpiler to get it to run in a browser, character replacability and runtime semantics don't matter. Typescript doesn't run in the browser, it's obviously a different language.
gleenn··on Bonsai: Janestreet's UI Library
Isn't that like saying the Internet is only written in English if you strip out all the non-English. All C-style languages are fully cross compatible if you only use semicolons.

I can't write Typescript into a browser without cross-compilation and "stripping out types" involves parsing and manipulating code. That's a different language.

gleenn··on Bonsai: Janestreet's UI Library
Clojurescript not ClojureJs, and Typescript doesn't run in the browser, it has the exact same issues/limitations: it must be compiled to JavaScript first.
gleenn··on Netflix employee fired for sharing personal details in retreat trust exercise
It's not, although rules vary by state. Medical professionals can prescribe it even though it's a Schedule III drug. I get ads for these presumably legitimate therapy services online all the time on major social networks.
gleenn··on China’s open-weights AI strategy is winning
Distilling isn't necessarily easy, there is a huge cottage industry of services middle-manning ChatGPT and Claude to collect huge amounts of data. It is still vastly cheaper than training yourself, but it is certainly not easy or feasible for most organizations. And I'm sure a flock of lawyers would show up if someone in America was found doing it.
gleenn··on ECC and DDR5
That particular quote did stand out to me. I think the counter claim is that if everyone uses software everywhere for everything, there is a very real societal cost for damaged data and if it's hard to detect then there is no way to prevent or measure harm. I think the "invisible hand" free market is showing some serious strain in modern times. People stopped using leaded-gas because it was causing measurable decreases in IQ for generations. I don't care how much you want to save a few dollars if it harms a lot of people and is difficult to measure. Everything else seems like a race to the bottom price so pushing the market in this manner doesn't bother me in the least. If you are running a server with others' data at stake, it seems like an obvious benefit for society on the whole to address the problem rather than serve some cheap datacenter operators.
gleenn··on AWS: Inaccurate Estimated Billing Data – $1.7 billion
One of the Mars landers famously failed due to unit conversion errors from metric to standard.
gleenn··on AWS: Inaccurate Estimated Billing Data – $1.7 billion
If someone quits their job, do all their opinions suddenly become suspect? You're kind of damned-if-you-do-damned-if-you-don't. Either you work for the company and you are biased one way, or you quit and now your bias is now suddenly the other way. I've joined and quit many jobs and my opinion may or may not have changed due to my change in status but it is clearly and ad hominem attack.
gleenn··on EEG shows brain can simultaneous encode two speech streams
Listening and responding are likely pretty different mental activities
gleenn··on Detecting LLM-Generated Texts with “Classical” Machine Learning
I think the fundamental problem is that training current SOTA AI models is very expensive. If a simple "classical" model can detect them, presumably at much lower algorithmic cost, then why wouldn't the model trainers use these same tools to feed back into their models to improve them at low cost to make them better? It's an arms race. Any cheap pattern can and presumably will be used to retrain if it becomes and effective way to catch AI.
gleenn··on SpaceX stock erases all its gains and slides below IPO price in intraday trading
I think one thing to point out is "everyone" in this context is probably the broader market, but the stock holdings aren't distributed uniformly. A few large investors could actually be sophisticated and unload a fortune and the rest of the shareholders could still largely still ignore fundamentals and suffer large losses. The broad market can be ignorant and the stock can (and is) be down, both things can be true.
gleenn··on John Deere owners will get the right to repair equipment under FTC settlement
"Tilting the windmill" is from Don Qixote who famously fights a windmill (which is a bit absurd) so he is courageous but also a bit foolish.
gleenn··on John Deere owners will get the right to repair equipment under FTC settlement
Extra props for tilting thw windmill that is tech behemoths funneling data to government agencies without oversight. Aiming at Amazon is certainly something not to be taken lightly.
