lovasoa··on The Google Play app review process now regularly takes longer than a week
We could force Google to operate its app review service independently. Users could use it and pay for it, or alternatives. Currently Google forces everyone to use their own mediocre service and pay for it without knowing exactly where and how much you pay.

lovasoa··on Any Human Ever – One life, drawn at random from all who have ever lived
In 429 CE, Devadatta was born on the Deccan Plateau, near present-day Hyderabad. His hamlet was home to about 100 people. Among six children, he was the second. Devadatta died of neonatal tetanus or sepsis within days of birth.

lovasoa··on Maximizing the value of your Claude Code sessions
I don't understand why changing effort levels busts the cache. Couldn't effort levels be a decoding-only thing where they just change the probability of the <end of thought> token? Are they literally adding a hidden system prompt that says "effort level: $level" ?

the writing has been on the wall for fifteen years, and yet the number of professional drivers has only increased since then...
lovasoa··on Gemini Robotics 2 brings whole body intelligence to robots
Of course we'll rent them! I don't even want to keep a robot in my flat all the time.

But that means speed does matter after all. The renting company will need to clean as many flats as possible with a single robot in a single day.

lovasoa··on Anatomy of a Frontier Lab Agent Intrusion: A Timeline of the July 2026 Incident
I was skeptical after last week's announcements, and I have to say I'm impressed now. Over the last two days, I reproduced the entire chain of components involved, and the exploits at play, and even though none of the exploits are crazy smart, the long series of pivots demonstrates a level of agency I didn't think today's LLMs had.

lovasoa··on Fast Remediation Is the New Trust Model (JFrog and OpenAI Zero-Day Findings)
The timeline is indeed a little bit fuzzy, I haven't found a precise chronology, neither from HuggingFace nor from OpenAI. HF says the hack happened "over a weekend", so probably July 11th-12th. Do you think it took OpenAI a week to realize what happened ?

Maybe when HF published their blog post on the 15th, OpenAI already knew something had happened, had started to investigate, and already reported the issue to JFrog ? But looking at your other comment in the thread, I agree that CVE-2026-65925 and CVE-2026-66014 are better candidates.

Taking a step back, so many basic vulnerabilities in a security-oriented product just makes the headline "agent autonomously escaped containment" sound a little less spectacular.

lovasoa··on Fast Remediation Is the New Trust Model (JFrog and OpenAI Zero-Day Findings)
There is one thing that is still unclear to me after reading a lot about the hack:

* were the ExploitGym solutions actually available somewhere inside huggingface's private datasets ?

* was the model really trying to extract the solutions ? or had some sub-agent drifted enough from the original context that it was not even trying to solve the initial challenge ? that would look much worse for OpenAI, PR-wise.

What they conveniently omit in the blog post is what the vulnerability was: it seems like they renewed JWTs without checking the signature at all ! You could write arbitrary info in an old token, and get it signed without any verification.

lovasoa··on I rewrote PostHog's SQL parser, 70x faster, while barely looking at the code
The thing I would have liked to know is why they don't use an existing fast SQL parser. Was being slightly incompatible with all existing SQL dialects a product requirement?
lovasoa··on OpenAI unveils its first custom chip, built by Broadcom
3) The engineers working on the chip used ChatGPT from time to time.
lovasoa··on Silurus/ooxml: Pixel-faithful Office documents, rendered in the browser
I tried a few PPTX files from consulting firms that are available online. The rendering does not seem to be truly pixel-perfect, but all of them were quite readable and had a good layout, which is already an impressive feat.

lovasoa··on Redis array: short story of a long development process
How much faster/slower are you with that process compared to writing code yourself?
lovasoa··on Is anybody else bored of talking about AI?
I use the latest codex with gpt5.4 and Claude opus every day. they hallucinate every day. If you think they don't, you are probably being gaslighted by the models.
lovasoa··on “Car Wash” test with 53 models
I was interested in the human results, so I had an llm build a visualization for them: https://codepen.io/lovasoaaa/pen/QwKWGBd

You can see that 17% of answers come from India alone and that software developers got below average results, for instance.

lovasoa··on Flux 2 Klein pure C inference
The author of this project is also the author of redis. He knows what he is doing.

Running inference for a model, even when you have all the weights, is not trivial.

lovasoa··on The struggle of resizing windows on macOS Tahoe
I use linux at home (with a HiDPI screen) and MacOS for work. The screen works well with both computers. I mostly just use a text editor, a browser, and a terminal though.

Linux has bugs, bug MacOS does too. I feel like for a dev like me, the linux setup is more comfortable.

How do you call the opposite of green washing? When you want to show that you are burning as much energy on training models as the others.

lovasoa··on SQLx – Rust SQL Toolkit
I use a fork of sqlx in SQLPage [1]. I think my main complaint about it is runtime errors (or worse, values decoded as garbage) when decoding SQL values to the wrong rust type.

lovasoa··on LLMs are more persuasive than incentivized human persuaders
No. The LLM's answer is correct.

lovasoa··on GPT-4.5
In the second handpicked example they give, GPT-4.5 says that "The Trojan Women Setting Fire to Their Fleet" by the French painter Claude Lorrain is renowned for its luminous depiction of fire. That is a hallucination.

There is no fire at all in the painting, only some smoke.

lovasoa··on Docker limits unauthenticated pulls to 10/HR/IP from Docker Hub, from March 1
If the electricity were generated by thousands of volunteers pedalling in their basement, then yes, I would expect the utility company not to be too greedy.
lovasoa··on Are LLMs able to notice the “gorilla in the data”?
I tried passing just the plot to several models:

    ChatGPT (4o):      Noticed "a pattern"
    Le Chat (Mistral): Noticed a "cartoonish figure"  
    DeepSeek (R1):     Completely missed it
    Claude:            Completely missed it
    Gemini 2.0 Flash:  Completely missed it
    Gemini 2.0 Flash Thinking: Noticed "a monkey"
lovasoa··on LLMs: Harmful to Technical Innovation?
This resonates with me. I used to love tinkering with "underdog" tech. I did frontends in svelte before it was cool. But for new projects, I now always default to react+tailwind, because that's what Claude knows best. And for the backend, I'm working on a SQL-only framework, because LLMs are now at almost 100% accuracy on text-to-sql.
