Geeking out on Bainbridge Island in the Pacific Northwest on cloud and circuits. Open water swimming is my poison. Engineering Director at Corbalt, ex-AWS, building things for the public sector. Opinions my own.

BlueSky was trying to make "skeet" not a thing, but I think this will do...

You forgot to mention that Oilers—who make up most of the engine room crew—start at $58,046.40 and are getting 0% raises through 2029.

This is... not good. Our ferry system is basically in free fall at this point. The WSF mechanics and engineers somehow ended up with 0% raises through 2029 via an arbitrator. Staffing is at bare minimums, and relies heavily on overtime for normal operations.

This was all just backend batch jobs, so my customer didn't care about cold starts. (There's no concept of CloudFront or an edge network in AWS GovCloud; even Route 53 is limited to private hosted zones.)

Why do we even need the LHC? We'll just have Katie Mack position the particles where they're needed, fusing them as necessary. 😉

On the customer side, nothing was observable (other than slower cold-start times). As the solutions architect for the customer, I heard about utilization woes from the Lambda team, though!

Lambda before Firecracker was… not pretty. Lots of wasted CPU. In GovCloud, even if I had just one 128 MB function on my account that stayed warm, it would occupy a full c3/c4.large!

I'm curious where this talk was taking this topic. Also, Brooke is an Aussie, not Kiwi, I thought?

Weird, I had never heard of this before. And I had even switched over to a Mac laptop by then, so somehow I missed this entirely. I doubt I'd ever use it, but I still find it weird that Apple launched and crashed an entire social network without me even being aware.

The problem with making all-day spaghetti is the aroma tantalizes you all day.
A pot of spaghetti sauce in a slow cooker. Bell peppers, celery, and onions are visible atop a red meat sauce.

As cute as the mobile lounges at Dulles are, I don't miss them (not needed for Alaska or Delta flights). Last few times was in the summer, with little/no air conditioning in them.

37!!! is a dangerous amount of paper.
Attempt at computing 37 factorial-factorial-factorial in Mathematica. Mathematica reports 8200794532637891559375 factorial as the answer. Attempting to force it results in an overflow.

I shied away from academia because I didn’t want to spend my life writing grant proposals; now I spend my time writing contract proposals. 🤦 And it’s the same: little/no correlation between contracts awarded and quality of R&D delivered.

What do you mean by VFD here? I can only expand it to vacuum fluorescent display, which I can’t fathom how someone could make at home.

I remember getting a peek at this on a behind-the-scenes tour as a kid. Reading up elsewhere[1], looks like it was 6502-based with Atari RIOT ICs (perhaps not surprising since both were founded by Nolan Bushnell). [1] github.com/palazzol/Cyb...

Thinking back to the OpenClawd incident where an agent started making derogatory posts against a maintainer who wouldn't merge its work: how long before these break into a CJIS system and start falsifying criminal records to remove obstructions?

"Ladies and gentlemen of the jury, it is well established that Apple does not allow their devices to be shown being used by bad guys. State exhibit 41 clearly shows my client using his iPhone. This clearly establishes my client's innocence of these horrific charges."

Commercial displays is the solution I've heard. They're more expensive; ads are subsidizing the household versions. (e.g., B&H: www.bhphotovideo.com/c/browse/Mul...)

Not just autocorrect but sudden UI changes in general, like search results suddenly populating right where I'm about to tap. UIs should ignore clicks/taps/submits made if the UI element has been there less than some human-reasonable threshold.

Being murdered again in 2026 in Stockton, UK, was a bit of a setback, but I'm now a prominent real estate professional in Seattle. No wonder I'm always tired. 2/2

Apparently, I was born in Wales, fought in WWI, joined the Royal Navy, and was assassinated in 1972. I didn't let this stop me, though; I then became a physician, serving in Antarctica, before switching over to Hollywood effects (Atlas, 2024). 1/2

On par with this: OAuth logins that open up in something other than a standard browser, making it impossible to use my password manager or passkeys.

The house I grew up in would make all sorts of pops after the sun set. As I kid, I was certain there was some stranger on the roof. We moved into a newly built house in my teen years. Similar pops, except sometimes nails would shoot out from the drywall because the frame was drying and contracting.

Correct me if I'm wrong, but weren't the "special" materials were just regular ferr(i/o)magnetic materials, chosen so their coercivity was just right? That is, the current from X+Y would flip it, while current from just X or Y by itself was below the hysteresis point.

It is supposed to be in the mid 80s in Portland today, and I'm not about to be wearing some scratchy space wizard cloak stuck to my sweaty skin. Rey's outfit seems more practical. Even up here, where the high is in the low 70s, cloak would be too much. Maybe later in the fall.

Once we're done migrating to IPv6 world-wide and turning off the last IPv4 server, it's time to start migrating from Referer to Referrer headers.

This seems like it would be a bit of a security nightmare given what we know today with speculative execution in one ISA affecting the other.

The two ideas I have: * Taking AWS' access management system (IAM) and making it applicable/usable anywhere: github.com/dacut/scratchstack * Connecting code and infrastructure-as-code together to do compile-time checks for breaking changes. (No work to show for this yet.)

Also, unless you own your own IP range, your traffic looks like it's coming from AWS' EC2 fleet, and a *lot* of sites block traffic from there.

I set this up for a couple labs, but it's only something you'd want to use if you have no other option (or have a perverse love of Microsoft RDS). Think: secured networks that aren't generally connected to the internet. aws.amazon.com/workspaces/

Is it still supported, or do you have to do bizarre things like scrape together Windows 98 images to get the development environment to work? I lament how CPLDs are falling by the wayside these days; they're perfect in hobbyist niches.
