A data pipeline is a software which runs on hardware. The software is error-prone and hardware failures are inevitable. It uses many possible geo-location attributes extracted from device fingerprint including country, state, city, zip-code, latitude, and longitude.

Apart from library code, maybe your application doesn't have frame pointers either, in which case everything is broken. The x86-64 ABI documentation shows how a CPU register, %rbp, can be used as a "base pointer" to a stack frame, aka the "frame pointer." Other types of profiling hit this more often.

And there are tools for archiving and indexing prompts for reuse, vector databases for retrieving documents that an AI can use to answer a question, and much more. That pricing won’t be sustainable, particularly as hardware shortages drive up the cost of building infrastructure. It’s also well suited to writing a quick email.

There's also a ZFS send/recv code path that should try to use the TASK_INTERRUPTIBLE flag (as suggested by a coworker), to avoid a kernel hang (can't kill -9 the process). LTS (April 2016).

In the simplest case, you have a growing workload, and you optimize it to run more efficiently so that you don’t need to buy or rent additional hardware, so your carbon footprint stays the same, but the carbon per transaction or operation is going down. I’ve written before about how to tune out retry storms.

I tried to tap the control key (virtual key code 162) once a second until the password input field appeared. On my home laptop it’s still more than 13 seconds of CPU time to go to sleep, almost all from Windows code. Is a second or more of busy waiting really the only way to get my hardware going?

There is no code or configuration change necessary to capture data and detect existing services. Lift & Shift is where you basically just move physical or virtual hosts to the cloud – essentially you just run your host on somebody else’s hardware. For that, it is sufficient to only know host-2-host dependencies.
