It is depressing listening to engineers I respected, who now just parrot incorrect information at me from their LLM. One smart engineer seems to have entirely offloaded all thinking and conversations to one, with just occasional editing. It

It's one of those "I hate it, but I get it" situations. Migrating metering over to a whole new format on AWS's scale is a scarily large undertaking.

I got known as a "Chaos Monkey" at AWS, and have sort of carried on that title. It's not exactly accurate, but tech stuff just breaks around me, and it's very, very rarely my fault. I'm pretty cautious and resist

Sure, and I would expect the COE called out the operational aspects. No one should have been in a position to be able to trigger that bug trivially (I don't remember if it came from a service, or if they injected the metering record t

I wonder if AWS billing still uses CSV files for passing data around. IIRC it was one of my first on-calls at AWS over a decade ago now, and I got a page early evening because some stuff we did with billing records broke because some "

I can secure myself first, so I'm never at fault. I never want to be the one to accidentally break production. Beyond that, I just keep advocating for more safe and secure approaches any opportunity I get.

I've been biasing towards VMs myself just out of caution, but maybe that's just extreme paranoia. The way I look at it is similar to how I'd look at any hypothetical employee. How do I ensure the agent only has access to the

The easiest, most guaranteed way to isolate it is to run it in a VM or container where it literally can't do the wrong thing without some kind of full container or VM exit exploit. It's not hard, it's trivial. Most folks her

Agreed. In my current job, across several large java code bases that have been developed over the last 12 years, the only place I've seen xml come into play is for maven. We've hundreds or more similar scale code bases and I don

Back around 10 years ago, I gained a new manager who had previously managed mechanical turk. It was already recognised as a dead end back then. I remember him talking about getting a mandate from Amazon Security to upgrade from the long EO

Not sure why you're getting downvoted, this is the entire point of open source. Does such a bug exist in Windows? OSX? Who checks? If someone finds the key in memory, can they tell what conditions might be causing it and where? Their

NUMA is one of those amazing things that trip you up in all sorts of ways at unexpected times. The amazing "invisible" performance killler (invisible because unless you're already aware of NUMA, or remember to check, you won

Intel suffers just as much when NUMA enters the picture, even prior to CCD style architecture. That extra latency hop across to the other core to get at memory is absolutely crippling, especially in a hot loop. It requires very careful hand

In theory having it in the same language could provide performance benefits, vs reaching out to a C library and dealing with C interop fun. Any language that is JIT'd would have native bytecode to optimise instead of a black box.

Working for an ISP in the mid 00s, the lack of security of those scripts was an absolute nightmare. It was a routine task to have to go clean up the mess they made, everything from simple "Being used to relay spam" on up.

There Is More Than One Way To Do It. That takes me back a bit. It's a perl-ism. I used to think it was a great design feature but I've come to strongly prefer "There should be one way to do it, and it should be obvious"

Gmail used to offer a low bandwidth / performance webmail interface, that was essentially their original UI. Ran like greased lightning, used barely any memory. Emails loaded almost instantly. It was nice while it lasted.

I'm not sure if it's still there, but for a long time Gmail offered a lightweight, simple HTML version of their site. Essentially the original UI for it. It was astounding just how quick it was, which really shows you how little
