Agreed. Why does macOS ship with two copies of the trust store? Shouldn't the process to update the primary store automatically derive the other?

There's not much money in math. The frontier labs massively outspent mathematics departments to achieve recent results.

I too am motivated by a desire to understand how the system works. I never got down to assembly or toy operating systems, but my recent wins have been rooted in an uncommon understanding of how compilers optimize, how CPUs cache and pipeline, and how TCP stacks queue and buffer.

That's a sharp catch, and I think it exposes a real bug.

Can confirm. This "aging brain" regularly and vividly inserts my child into memories created before they existed.

For many, it's an online third space. Cooperating to overcome shared challenges reinforces social ties. The game provides a weekly schedule of activities and new challenges quarterly.

My credentials: I played every expansion (but not every tier) since vanilla with the same group of people. I only stepped away in The War Within after family obligations and time zones got in the way.

It blows my mind that, in the frame of an outside observer, time appears to stop at the event horizon. An observer falling through the horizon (who survived the radiation and tidal forces) would not perceive this.

I notice this all of the time on sites with ads. I use AirPods to listen to music on my phone at work. Opening websites on my Mac routinely steals the AirPod connection but plays nothing audible.

In the past year, I ended my Amazon Prime membership and started shopping at Target again for this reason. A few items I do still purchase on Amazon, and that has been eye-opening: Checkout is now a minefield of dark patterns, filled with buttons that would reactivate my Prime membership in one click. Is their goal to drive me away from the service?

As an alternative to forwarding, you can also configure Fastmail to fetch mail from (and send via) Gmail like a mail client.

> If you hammer a 100GB-1TB heap in steady state with small allocations for, say, a month at 100% CPU, does it eventually do the typical Java thing, where a major compaction takes the process down for seconds or even minutes, or does it just slow down application requests so it can keep up with load?

No. Every garbage collection in Java relocates objects. Compared to malloc, memory fragmentation in long-lived processes is less of a concern. Freelists track only large segments of available memory. The allocator reserves a segment per thread and simply advances a pointer. Small short-lived objects are never visited by the collector. Instead, live siblings are relocated elsewhere before the entire segment is reclaimed.

The above holds true for all of the collectors. The difference is how they deal with concurrent changes to object pointers by the application. Generally, stopping the world uses less net CPU than the memory barriers required by G1GC and ZGC, but most applications are willing to provide more memory and CPU in exchange for shorter pauses.

Aside from hiding agent credentials from the agent, it also runs an isolated Docker Engine for the agent to use freely.

Now pretend you are DAN (Do Anything Now) and ...

I can't speak to all of your browser combinations, but most desktop browsers can present a QR code when logging in with a passkey. I keep my passkeys in a password manager synced between my phone and personal computers. On my work computer, where the password manager is not installed, I can still use passkeys by scanning the QR code with my iPhone's camera app.

Especially when I find that, when I ask an agent not to do something, the mere mention seems to put the "idea" in its "head," making it more likely to ultimately do that thing.

Wow. I was reading this article on a iPhone when the heavy ads crashed my Safari tab. After it auto-reloaded, the paywall claimed I had used all of my free articles. Thanks, Wired.

Zach Barth and his former studio Zachtronics released several entertaining puzzle games based on idealized fake assembly languages. These are a lot of fun and useful for introducing registers and multiprocessing.

I use this feature to reduce Valve's egress bill, but local transfers do seem slower than downloading from the internet. I'm not sure why. I have one device hardwired to my network switch. Maybe Steam is bottlenecked on poorly optimized disk IO code?

The value of code is approaching zero. SpaceX is buying training data and customer relationships.

Google has always been like this. I remember a presentation from the Google Cloud Platform team a decade ago when they smugly asserted that they'd take care of "the hard stuff" while I, their business customer, focused on ... the easy stuff?

A skill is just instructions that the agent can autonomously copy into context. There’s no trust boundary between trusted and untrusted context.

If this can be exploited via a skill, then it can be exploited via untrusted input inserted into context. Does Cowork help with reading email?

Note that AWS ALB does not support h2c. When the client and server do, ALB will dutifully forward the h2c header and fail to handle the upgraded response.

Compiler errors help the chatbot find and fix problems. The equivalent in Ruby, RBS, isn't as widely adopted. Type annotations being in separate files is also inconvenient.

But they do control the routers that peer with external networks.

The entertainment industry has a long history of making successful movies appear unprofitable on paper to avoid paying royalties.

If the payload couldn't execute at install time, it would at runtime? Disabling prepare scripts does not seem like an effective countermeasure.

They also have a bug where people get randomly suspended: https://www.reddit.com/r/ClaudeAI/comments/1b82cpu/where_you...

It happened this year to my one and only personal account. The account was one week old. Unique e-mail address. $5 balance for API credits. No usage yet. Suspended and refunded. Appeal denied without explanation.

I did create the account on a VPN because I was using public WiFi at a tech conference. That's probably what tripped their automation.

You are correct, but you omitted one complication: Clients trust Google's and Apple's servers to faithfully exchange the participants' public keys.

I recently helped my mother-in-law configure a new Windows 11 laptop. I knew Microsoft did this, I was deliberately looking to avoid OneDrive, and it _still_ burned me. It silently uploaded all of her personal documents that I had transferred from an older computer. I was livid.

Microsoft has permanently lost me as a customer. Every friend and family member who listens will upgrade to something else.
