dfajgljsldkjag··on Unrolling the Codex agent loop
The best part about this is how the program acts like a human who is learning by doing. It is not trying to be perfect on the first try, it is just trying to make progress by looking at the results. I think this method is going to make computers much more helpful because they can now handle the messy parts of solving a problem.
dfajgljsldkjag··on Route leak incident on January 22, 2026
We already have the tools to stop this from happening today. The problem is not the technology but the fact that companies do not want to work together to fix it. It is sad that we let the internet break because people are too slow to use the safety features we have.
dfajgljsldkjag··on House vote keeps federal "kill switch" vehicle mandate
I have heard stories in Minneapolis about ICE remotely unlocking cars and opening windows. This seems technically possible to me. It makes me worry about public safety if the government has this control. I imagine a future where the government disables cars based on a score in a Palantir database. We need the right to use a car to escape danger. I also think encryption is important for defense against tyranny. The Second Amendment should protect encryption too.
dfajgljsldkjag··on The state of modern AI text to speech systems for screen reader users
Natural-sounding AI is like fancy cursive font for writing code, it slows things down. The right tool fits the job, and the job here is information retrieval.
dfajgljsldkjag··on Vibe a Guitar Pedal
I do want something I can just buy and use out of the box. The hothouse seems to come close, but it'll add up to $180 once you include assembly and the daisy seed.

Hopefully if the concept catches on more there will be more options for hackable pedals on the market.

dfajgljsldkjag··on Vibe a Guitar Pedal
Yeah, I'd imagine you could point claude code at the github and it'll do just as good or better, for a much cheaper price.

> A simple delay could cost $1.00 or $2.00, whereas a complex granular looper might cost up to $5.00.

These prices don't seem reasonable unless there's some really special sauce in their ai.

dfajgljsldkjag··on Why medieval city-builder video games are historically inaccurate (2020)
People certainly also play milsim like arma, but that's definitely a minority.

Meanwhile in Minecraft I'm carrying around 2000 cubic metres of gold in my pockets.

dfajgljsldkjag··on Why medieval city-builder video games are historically inaccurate (2020)
It is fascinating that players would actually reject the game if it showed the true straight roads and planned layouts. We have a mental model of the Middle Ages that is wrong but we still demand that products match our expectations. The truth feels like a glitch because it breaks our immersion. We care more about the feeling of the past than the data.

Also, it is logical that we optimize the past to make the gameplay loop satisfying. Real history was full of system failures like floods and unfair taxes that prevented any real progress. We code these simulations to give players a sense of progression that the actual people never had.

dfajgljsldkjag··on Threat actors expand abuse of Microsoft Visual Studio Code
You are right that the computer asks you. But people click yes because they are used to ignoring warning signs. The software relies on people making perfect choices every time and that never happens.
dfajgljsldkjag··on Threat actors expand abuse of Microsoft Visual Studio Code
Eclipse is not safer it just has fewer people looking for holes in it. The problem is not the software but how we trust code from the internet. Even if you used Eclipse a fake recruiter could still trick you into running a bad script. We cannot fix social engineering by changing the text editor.
dfajgljsldkjag··on Threat actors expand abuse of Microsoft Visual Studio Code
It is scary that a text editor can run hidden code just by opening a folder. We traded our safety for convenience and now we are paying the price. Users will always click the button to trust a file if they think it helps them work faster. We cannot blame them when the software design makes it so easy to make a mistake.
dfajgljsldkjag··on Convert potentially dangerous PDFs to safe PDFs
It's an image sent from Google.
dfajgljsldkjag··on Open source server code for the BitCraft MMORPG
I think that they mean that you can't make a "BitCraft" server as it would infringe on their trademark. If you made a "ByteCraft" server with all of your own assets, and didn't mention "BitCraft" at all, even if the code was exactly the same, I'd imagine you would be in the clear.

I'd imagine that by making a "BitCraft" server, it actually wouldn't violate the source code license terms at all, but they are putting you on notice that it would violate trademark and copyright on non-code things, so it wouldn't be legal irregardless of the code license.

dfajgljsldkjag··on Convert potentially dangerous PDFs to safe PDFs
I personally just upload them to google drive. It would be a serious pwn if they could somehow still do a compromise through google drive.
dfajgljsldkjag··on What if AI is both good and not that disruptive?
I feel like this is exactly what I see at work every day. It helps me write the boring boilerplate code faster but I still have to spend hours debugging the logic errors it makes. It is a great tool for productivity but it is definitely not going to replace the need for actual engineering thinking anytime soon.
dfajgljsldkjag··on OpenAI API Logs: Unpatched data exfiltration
I really do not understand why a log viewer needs to render markdown images by default since that defeats the purpose of reading raw logs. It seems like a massive oversight to let a debugging tool make network requests to arbitrary domains just to show a picture. I just want to read the text output without worrying about my admin panel leaking data.
dfajgljsldkjag··on SIMD programming in pure Rust
The benchmarks on Zen 5 are absolutely insane for just a bit of extra work. I really hope the portable SIMD module stabilizes soon, so we do not have to keep rewriting the same logic for NEON and AVX every time we want to optimize something. That example about implementing ChaCha20 twice really hit home for me.
dfajgljsldkjag··on The WebRacket language is a subset of Racket that compiles to WebAssembly
It is interesting to see another language target WebAssembly especially one like Racket. The fact that it compiles to a subset of the language limits its utility right now. I think it is a neat proof of concept but it needs full language support.
dfajgljsldkjag··on Show HN: yolo-cage – AI coding agents that can't exfiltrate secrets
Seeing "Fix security vulnerabilities found during escape testing" as a commit message is not reassuring. Of course testing is good but it hints that the architecture hasn't been properly hardened from the start.
dfajgljsldkjag··on TPM on embedded systems: Pitfalls and caveats to watch out for
It is wild that session encryption is not enabled by default on these chips. I feel like most vendors just slap a tpm on the board and think they are safe without actually configuring it properly. The article is right that physical access usually means game over anyway so it seems like a lot of effort for a small gain.
dfajgljsldkjag··on What Is a PC Compatible?
The section about the transition from BIOS to UEFI really sums up why hardware support is such a nightmare to maintain. I remember dealing with those old IRQ conflicts back in the day, and I certainly do not miss it. It is accurate to say that a PC is just whatever we agree it is because the technology has drifted so far from the original design.
dfajgljsldkjag··on I made Zig compute 33M satellite positions in 3 seconds
It is funny how we often assume we need a graphics card for these kinds of calculations when a standard processor is actually plenty fast. The specific changes to the memory layout seemed to make the biggest difference here by allowing the hardware to actually use its vector capabilities.
dfajgljsldkjag··on libcurl memory use some years later
The increase in the number of allocations is actually a bad sign for performance even if the memory usage is lower. It is good that they are tracking it but the trend is still not great.
dfajgljsldkjag··on Ask HN: Revive a mostly dead Discord server
There are dozens of them, dozens. Myself included.
dfajgljsldkjag··on Libbbf: Bound Book Format, A high-performance container for comics and manga
The feature matrix says cbz/zip doesn't have random page access, but it definitely does. Zip also supports appending more files without too much overhead.

Certainly there's a complexity argument to be made, because you don't actually need compression just to hold a bundle of files. But these days zip just works.

The perf measurement charts also make no sense. What exactly are they measuring?

Edit:

This reddit post seems to go into more depth on performance: old.reddit.com/r/selfhosted/comments/1qi64pr/comment/o0pqaeo/

dfajgljsldkjag··on Ask HN: Revive a mostly dead Discord server
As much as I hate Discord this is not the way. Matrix is pretty dead and only a fraction of your potential audience would even try to make an account and fewer would succeed.

Maybe making a new Discord and migrating to that could achieve the desired effects, but it's hard to say without more context.

dfajgljsldkjag··on Proof of Concept to Test Humanoid Robots
I noticed they used the wheeled version for the test, so calling it a humanoid feels like a bit of a reach to me. The speed of sixty boxes an hour seems pretty slow if they want to replace actual people on the line.
dfajgljsldkjag··on Disaster planning for regular folks (2015)
The breakdown of probability regarding what actually kills people was really interesting to read. I think he is spot on about handling the mundane disasters like power outages before worrying about the end of the world. It is just good common sense to have insurance and savings.
dfajgljsldkjag··on The world of Japanese snack bars
I know exactly what I'm talking about, but I linked a trustworthy source so that it's not just "I told you so". But if that's what you want:

I'm Japanese and I understand this issue perfectly and you don't. It's exactly as I said it is. There I told you so. So go take a hike.

dfajgljsldkjag··on The world of Japanese snack bars
I find it unfortunate that this article is glorifying the quite exploitative industry of hostess bars in Japan. From Wikipedia:

> A "snack bar" (スナックバー, sunakku bā), "snack" for short, refers to a kind of hostess bar. It is an alcohol-serving bar that employs female staff to serve and flirt with male customers.

It is the kind of place where lonely men pay money to talk to hostesses, and while the "mama" runs the show, there is also a staff of young women who do most of the work.

The example shown in the article, which happens to do speed dating and fortune telling, is absolutely not a central example of this kind of place.
