Project mention: Summarization experiments with Hugging Face Transformers - part 1 | dev.to | 2025-07-14Now, I can't copy the YouTube video descriptions verbatim for SEO purposes: search engines don't like duplicate content. The obvious solution is to do some kind of summarization. First of all, I always use whisper and proofread the SRT file containing the recognized audio before uploading it to YouTube. I then copy the SRT file verbatim in an LLM chat, in chunks, and ask ChatGPT to generate a summary once I say so. This last step is tedious and you always rely on a SaaS. Some alternatives include the use local AI models via Ollama, or more specialized software that can run different tasks besides text generation.

> I didn't realize how important order was to type inference.
I was unclear, I'm afraid. You can reorder the type parameters, it just changes which of them you need to specify: https://go.dev/play/p/oDIFl3fZiPl
The point is that you can only leave off elements from the end of the list, to have them automatically inferred.
> Are there any real packages out there using these techniques?
I think so far, the usage of generics for containers in Go is still relatively sparse, in public code. I think in part that is because the documentation of how to do that is relatively sparse. That is part of the motivation for the post, to have a bit of somewhat official documentation for these things, so they become more widely known.
The standard library is just starting to add generic containers: https://github.com/golang/go/issues/69559 And part of that is discussing how we want to do things like this: https://github.com/golang/go/issues/70471
That being said, I have used the pointer receiver thing in my dayjob. One example is protobuf. We have a generic helper to set a protobuf enum from the environment. Because of how the API was designed, that required a pointer receiver constraint.

Moby
The Moby Project - a collaborative project for the container ecosystem to assemble container-based systems
Project mention: Docker Engine v28: Hardening Container Networking by Default | news.ycombinator.com | 2025-05-12Docker networking defaults have been tightened up but per https://github.com/moby/moby/issues/22054#issuecomment-28714...:
the default binding address is still 0.0.0.0.
There are now rules in raw-PREROUTING to drop packets sent from outside the host to container addresses, and to ports mapped to the loopback address. Rules in the filter-FORWARD chain no longer depend on its default policy.

Project mention: Why Clean Architecture Struggles in Golang and What Works Better | dev.to | 2024-11-04
When designing a Go project, look to real-world examples like Kubernetes, Vault and the Golang Standards Project Layout. These showcase how powerful Go can be when the architecture embraces simplicity over rigid structure. Rather than trying to make Go fit a Clean Architecture mold, embrace an architecture that’s as straightforward and efficient as Go itself. This way, you’re building a codebase that’s not only idiomatic but one that’s easier to understand, maintain, and scale.

rclone
"rsync for cloud storage" - Google Drive, S3, Dropbox, Backblaze B2, One Drive, Swift, Hubic, Wasabi, Google Cloud Storage, Azure Blob, Azure Files, Yandex Files
Project mention: Two guys hated using Comcast, so they built their own fiber ISP | news.ycombinator.com | 2025-07-14Just offering some advice if you aren't aware. If you are, freely ignore.
For convenience, the rclone tool is nice for most cloud storage like google and stuff that make rsync annoying[0]
rsync also offers compression[1], and you might want to balance it depending if you want to be CPU bound or IO bound. You can pick the compression and level, with more options than just the `-z` flag. You can also increase speed by not doing the checksum, or by running without checksum and then running again later with. Or some intervaling like daily backups without and monthly you do checksums.
If you tar your files up first I have a function that is essentially `tar cf - "${@:2}" | xz -9 --threads $NTHREADS --verbose > "${1}"` which uses the maximum `xz` compression level. I like to heavily compress things upstream because it also makes downloads faster and decompression is much easier than compression. I usually prefer being compute bound.
Also, a systemd job is always nice and offers more flexibility than cron. It's what's helped me most with the wack-a-mole game. I like to do on calendar events (e.g. Daily, Weekly) and add a random delay. It's also nice that if the event was missed because the machine was off it'll run the job once the machine is back on (I usually make it wait at least 15 minutes after machine comes online).
