Even with "E2E" encryption with iMessage, you're still trusting Apple completely and totally with key distribution. If a new device is added to your account by an attacker or by Apple themselves, your existing devices will ha

How does this square with FOIA obligations? I get ICE sidestepping transparency by avoiding creating the responsive footage in the first place, but once the body cam footage exists, what basis could they use to withhold it other than redact

That's going to be on the $20 plan. IIRC the $100 and $200 plans keep the 50% fable usage.

You need at least twice the frequency range for sample rate in order to represent the original signal. That's slightly misleading though, that's from the Nyquist-Shannon sampling theory and it's a mathematical fact but that i

That's a halted firewall setup. Normally as part of shutdown you would tear down networking in SysVinit or systemd but you don't actually have to do that. When shutting down you can choose whether to power off or just to halt. It&

Like when Runescape allowed you to purchase membership via a premium rate number. Lots of fraud going on back when that was a thing and a big part of why it's no longer a thing.

There are some typos like "if" instead of "of" that seem to imply at the very least, some of it is verbatim written by a person. Given the subject matter, I'd be extremely surprised if this was 100% AI but one thing

A bootable container, kernel included, is not a container. Building a whole new OS image for patches isn't a bad idea, but depending on the workload this might be a non-starter. At the very least, make updates to the OS image increment

Thorium isn't fissile, it's fertile. All thorium reactors work by breeding that thorium into uranium.

While DAOS looks cool, from their roadmap it looks like they still don't have a fault domain larger than a server... Their erasure coding profiles also look pretty thin. I'm ex-Meta, our infra had vastly different availability and

You can shrink XFS, but only the realtime volume. All you need is xfs_db and a steady hand. I once had to pull this off for a shortened test program for a new server platform at Meta. Works great except some of those filesystems did somehow

If you already know the checksum for some huge chunk of the message then you don't need to recompute it to append some data and get a new checksum (at least for CRC). On the read side you would want to have checksums at whatever granul

Wifi would probably be the easiest. Either hide a dummy AP in the house or use a combination of multiple neighbors APs. If you don't see any beacon frames from the dummy SSID for a 30 second period then lock/shred the computer.

For some trivial client side filtering that still makes it e2e encrypted.

iMessage is not on the same playing field as Whatsapp and Signal. Apple has full control over key distribution and virtually no one verifies Apple isn't acting as a MitM. Whatsapp and e2e encrypted messenger force you to handle securel

Are you talking about Brian Steel? He was held in contempt because he refused to name his source that informed him of some misconduct by the judge (ex parte communication with a witness). That's hardly relevant here, the client wasn&#x

That in particular would fall under the crime-fraud exception so there's no attorney client privilege.

Right, but the comment I was replying to was in response to this: > 2 will tell you if they diverge, but you lose both if they do. 3 let's you retain 2 in operation if one does diverge. If you care about resilience then you either n

Disclaimer: I work at Meta and I know a couple of the authors of the paper but my work is completely unrelated to the subject of the paper. That's not a technical error, they mean SRAM in the CPU itself. You're right about gcj but

But if it's a consistent fault, like the silent data corruption covered in the linked paper, redoing the computation is still going to end up with no way to identify which core is faulty. If it's an intermittent fault, then even f

Actually it's not uncommon for there to be ECC used within components as a method to guard against stuff like this. I don't think it's practical to ever have complete coverage without going full blown dual/triple redunda

Backblaze B2 is their generic object storage platform similar to S3. You pay what you use and it scales into petabytes. There's no minimums so if you're only using small amounts, you get a small bill at the end of the month. It&#x
