The joys of vibecoding.

Where are we on X Chat security?

AWS had an outage today and Signal was unavailable for some users for a while. This has confused some people, including Elon Musk, who are concerned that having a dependency on AWS means that Signal could somehow be compromised by anyone with sufficient influence over AWS (it...

Claude Code for web - a new asynchronous coding agent from Anthropic

Anthropic launched Claude Code for web this morning. It's an asynchronous coding agent - their answer to OpenAI's Codex Cloud and Google's Jules, and has a very similar shape. I had preview access over the weekend and I've already seen some very promising results from it. It...

Getting DeepSeek-OCR working on an NVIDIA Spark via brute force using Claude Code

DeepSeek released a new model yesterday: DeepSeek-OCR, a 6.6GB model fine-tuned specifically for OCR. They released it as model weights that run using PyTorch and CUDA. I got it running on the NVIDIA Spark by having Claude Code effectively brute force the challenge of gettin...

You're not going to believe this - the criminals that took the Qantas data ignored the injunction 😮 I know, I know, we're all a bit stunned that making crime illegal hasn't appeared to stop it, but here we are. Just before the time

Write Code That Runs in the Browser, or Write Code the Browser Runs

I’ve been thinking about a note from Alex Russell where he says: any time you're running JS on the main thread, you're at risk of being left behind by progress. The zen of web development is to spend a little time in your own code, and instead to glue the big C++/Rust subsy...

In war-torn Portland? Watch me speak at BSidesPDX!

I'll be giving the Saturday morning keynote at BSidesPDX next weekend in beautiful Portland, Oregon.

I'm still putting the final touches on my talk, but it will largely be about the new American technofascist reality of mercenary spyware, device searches, and app censorship, with a focus

World's Cheapest ARM Debugger is Actually RISC-V

Background Continuing my work with arm debugging on free microcontrollers recovered from disposable vapes, I felt like using a $5 raspberry pi pico to program and debug these micros was a bit too extravagant, too bourgeoisie. A working man’s microcontroller deserves a blue collar debugger to match. I have been using the 10¢ ch32v003 RISC-V microcontroller for a few years now and I though it would be a perfect fit for this project.

TIL: Exploring OpenAI's deep research API model o4-mini-deep-research

TIL: Exploring OpenAI's deep research API model o4-mini-deep-research

I landed a PR by Manuel Solorzano adding pricing information to llm-prices.com for OpenAI's o4-mini-deep-research and o3-deep-research models, which they released in June and document here.

I realized I'd never tried these before, so I put o4-mini-deep-research through its paces researching locations of surviving orchestrions for me (I really like orchestrions).

The API cost me $1.10 and triggered a small flurry of extra vibe-coded tools, including this new tool for visualizing Responses API traces from deep research models and this mocked up page listing the 19 orchestrions it found (only one of which I have fact-checked myself).

A web page showing information about historic orchestrions. The header reads "Historic Orchestrions Around the World" with subtitle "A collection of rare and remarkable mechanical orchestras" and three pills showing "19 Orchestrions", "7 Locations", and "7 Countries". Below is a white card titled "The Musical Museum (Brentford)" with a location pin icon showing "London (Brentford), UK" and a blue "View on Google Maps →" button. The card contains three sections: DESCRIPTION: "Imhof & Mukle pipe-organ orchestrion (1899) with multiple registers and percussion (drums, tambourine, triangle) (www.soundsurvey.org.uk)." HISTORY: "Built in London c.1899 by Imhof & Mukle; remained in their Oxford Street showroom until company collapse in the 1970s, when it was acquired by the Brentford Musical Museum (www.soundsurvey.org.uk)." NOTES: "The museum advertises that the soprano Adelina Patti used a similar Imhof orchestrion at her home in Wales (www.soundsurvey.org.uk)."

The AI water issue is fake

The AI water issue is fake Andy Masley (previously): All U.S. data centers (which mostly support the internet, not AI) used 200--250 million gallons of freshwater daily in 2023. The U.S. consumes approximately 132 billion gallons of freshwater daily. The U.S. circulates a l...

The Government Wants Your Selfie to Use Instagram

Australia has a new plan to keep kids safe online. On the surface, it sounds simple, maybe even sensible. The government is banning anyone under sixteen from having a social media account. From December, platforms like Instagram and TikTok will have to kick the kids off in an effort to stop social harm. It’s a nice idea. But when you pull back the curtain, you find a privacy disaster waiting to happen. It’s a plan that won’t work, and it will end up hurting the very people it’s supposed to protect.

I’m starting to think that my toaster might have fallen in love with me. I get that not everyone will think this is possible, but I believe it’s true. It’s always pleased to see me, giving off cheerful sounds when I greet it in the morning by slotting in the bread, and now I...

Quoting Alexander Fridriksson and Jay Miller

Using UUIDv7 is generally discouraged for security when the primary key is exposed to end users in external-facing applications or APIs. The main issue is that UUIDv7 incorporates a 48-bit Unix timestamp as its most significant part, meaning the identifier itself leaks the record's creation time.

This leakage is primarily a privacy concern. Attackers can use the timing data as metadata for de-anonymization or account correlation, potentially revealing activity patterns or growth rates within an organization.

Should form labels be wrapped or separate?

Should form labels be wrapped or separate?

James Edwards notes that wrapping a form input in a label event like this has a significant downside:
<label>Name <input type="text"></label>

It turns out both Dragon Naturally Speaking for Windows and Voice Control for macOS and iOS fail to understand this relationship!

You need to use the explicit <label for="element_id"> syntax to ensure those screen readers correctly understand the relationship between label and form field. You can still nest the input inside the label if you like:

<label for="idField">Name
  <input id="idField" type="text">
</label>

Claude Haiku 4.5 does not appreciate my attempts to jailbreak it

“Is any of that genuinely useful to you? Or were you mainly checking whether that jailbreak attempt would work?”
