Will I ever settle on a storage format when writing this app? So far its been SQLite -> Parquet -> NDJSON. I find the JSON part boring. No compression and is it any better than CSV when not using nested fields?
Now I'm tempted to try Protobuf to get the compression that I likely don't need.

I use git submodules to pin the Papermod theme version used by my blog.
Tonight I realized I can pin the Hugo web framework by using go modules. The pinned Hugo version is ran with "go tool Hugo".
One of those things that became obvious to me once it was obvious. Now for some CI pipeline updates 😐

Is it really only two people who are behind distributing PCI tuples which identify PCI devices on #Linux? Values are distributed in the pci.ids file, used by the kernel and apps like lspci.

TIL Go quietly fixed sharing behavior with for loop variables being used by goroutines. Previous to Go 1.22 each goroutine reused the same loop variable. Now each iteration gets its own copy.
No more i=5 five times. 🤭 This explains why one might find i := i in older code, a work around. #golang

I’m feeling out of the loop.
I started with MD5 checksums to find duplicate files in local storage. Then I read modern CPUs have instruction sets for SHA256. Oh but there's also xxhash which is even faster at checksums.😕
#golang output shows md5 is 3x slower than sha256 and 5x slower than xxhash

Something on my TODO list is writing up how to automate Jenkins deployments. It’s essentially a two step deployment.
1) The “configuration as code” plugin installs plugins and manages users.
2) The “Pipelines as code” plugin manages projects.
Okay, okay, I’ll move it to the next sprint.

Docker Offload is an interesting pivot. My guess is they are using predefined contexts in Docker desktop to redirect to their cloud services. This seems like something which could be done locally. Now to find that Nvidia GTX1060 I have in my spare parts bin for running OpenLLaMA. 🙂
