Users are concerned about the implications of this vulnerability, with some questioning the decision to disclose it to Mozilla.

Very cool research and wonderfully written. I was expecting an ad for their product somewhere towards the end, but it wasn’t there! I do wonder though: why would this company report this vulnerability to Mozilla if their product is fingerprinting?

Others are critical of the architecture that led to this vulnerability, suggesting alternative solutions.

Why is this global keyed only by the database name string in the first place? The post mentions a generated UUID, why not use that instead, and have a per-origin mapping of database names to UUID somewhere?

Mitigating the Risk

Users can take steps to protect themselves, such as exiting Tor Browser at the end of each session and avoiding mixing different uses in one session.

Make sure to exit Tor Browser at the end of a session. Make sure not to mix two uses in one session.

• Building a cloud can be cost-effective with the right strategy
• Traditional cloud companies may charge high prices for services
• Autoscaling and backup are key considerations for a reliable cloud setup

The Internet’s Verdict: 70% Hyped, 30% Skeptical

Introduction to Cloud Building

Cloud building is a complex task that requires careful planning and execution. As one forum user noted,

i just use Hetzner. Everything which cloud companies provide just cost so much, my own postgres running with HA setup and backup cost me 1/10th the price of RDS or CloudSQL service running in production over 10 years with no downtime.

Benefits and Challenges

Building a cloud can be beneficial for companies that want to have control over their infrastructure. However, it also requires a significant amount of expertise and resources. Another user commented,

Potentially useful context: OP is one of the cofounders of Tailscale. Traditional Cloud 1.0 companies sell you a VM with a default of 3000 IOPS, while your laptop has 500k.

Despite the challenges, some users are enthusiastic about building their own cloud. As one user said,

Hahaha! Have fun! I‘m doing the same – together with Claude Code. Since August. With https (mTLS1.3) everywhere, because i can.

Conclusion

Building a cloud can be a cost-effective and reliable option for companies that are willing to invest time and resources. With the right strategy and expertise, it is possible to create a scalable and secure cloud setup.

Forum Reactions:

Users are concerned about the implications of this vulnerability. As one user noted:

Why would this company report this vulnerability to Mozilla if their product is fingerprinting? Isn’t it better for the business (albeit unethical) to keep the vulnerability private, to differentiate from the competitors?

Another user emphasized the importance of proper browser hygiene:

Make sure to exit Tor Browser at the end of a session. Make sure not to mix two uses in one session.

Technical Implications:

The identifier can persist as long as the Firefox process remains running. However, it does not persist past browser restart, which reduces its usefulness to attackers.

Some users are looking for academic research on this topic, beyond activist groups like the EFF.

• Apple fixes iPhone bug that allowed cops to extract deleted chat messages
• Notification texts were stored on a local database outside of the messaging app
• Users can change settings to only show notification alerts without content

The Buzz Score

The Internet’s Verdict: 70% Hyped, 30% Skeptical

What’s the Issue?

The bug allowed notifications to be retained on the device even after the app that generated them was removed.

This was a bug that left it cached on the device. Apple and Google have put themselves in the middle of most notifications, causing the contents to pass through their servers, which means that they are subject to all the standard warrantless wiretapping directly from governments, as well as third-party attacks on the infrastructure in place to support that monitoring.

Impact and Solution

The impact of the bug was that notifications marked for deletion could be unexpectedly retained on the device.

A logging issue was addressed with improved data redaction, with a CVE-2026-28950 classification.

Oh, I was originally confused about this because I had thought the push notifications were end-to-end encrypted, so they couldn’t be cached in readable form by the push notification service, and only decrypted by the app on device upon receiving the notification. But it seems like after the notification was decrypted by the app and shown to the user using OS APIs, the notification text was then stored by the OS in some kind of notification history DB locally on the device?

Conclusion

Apple’s fix addresses the issue, but users should still be aware of their notification settings to maintain privacy.

The Internet’s Verdict: 70% Hyped, 30% Skeptical

Forum Voices

Many people are excited about the prospect of low-tech tractors, citing the simplicity and reliability of older models.

Up until a year ago I was regularly using a Massy Fergusson 135, made sometime in the 1970s. It was wonderful! So amazing to drive and use.

Others are skeptical, pointing out the importance of technology in modern agriculture.

I think this is a reaction to the incredibly locked down ecosystem that most of these mfgs are pushing. However, the tech exists for a reason and is not inherently bad, the issue is the lock-in, the lack of choice and interoperability.

Implications

The sale of low-tech tractors raises questions about the role of technology in agriculture. While some see it as a step backward, others see it as a way to increase accessibility and affordability.

Expert Analysis

Experts are weighing in on Google’s new TPU chips.

I already felt that gemini 3 proved what is possible if you train a model for efficiency. If I had to guess the pro and flash variants are 5x to 10x smaller than opus and gpt-5 class models.

Technical Specifications

The new TPU chips deliver up to two times better performance-per-watt over the previous generation.

TPU 8t and TPU 8i deliver up to two times better performance-per-watt over the previous generation

Google’s vertical integration in AI gives them a unique advantage.

Google can design their chips and engine and systems in a whole-datacenter context, centralizing some aspects that are impossible for chip vendors to centralize

So, is it like colinux, but for pre-NT windows? Neat! Back when I was still using windows (probably XP era), I used to run colinux, it was kind of amazing, setting up something like LAMP stack on the linux side was a lot easier and then using windows editors for editing made for quite nice local dev env.

Making RAM at Home

Executive Summary:

• Making RAM at home is a complex process.
• It requires a clean room lab with positive pressure.
• Experts are skeptical about the feasibility of this project.

The Internet’s Verdict: 70% Hyped, 30% Skeptical

Introduction to RAM Making

Making RAM at home is not a straightforward process. As one expert notes,

I only buy free-range artisanal DRAM at the DRAM farmer’s market.

Technical Challenges

Creating a clean room lab is a significant challenge.

I saw this video yesterday and considered posting it, but I wasn’t sure if it was appropriate for HN. This channel has another video where it shows how the clean room lab is created starting from a basic backyard shed, and that was truly astounding.

The positive pressure required to keep particles low is almost impossible to achieve in a home setup.

Others are skeptical about the project’s practicality.

I’m not sure this is what they meant when they said they wanted to bring manufacturing back to the USA lol
