   WinCse – Integrating AWS S3 with Windows Explorer▲65

   I previously introduced WinCse on Hacker News (original post: https://news.ycombinator.com/item?id=43947599). At the time, it only supported AWS S3, but this update adds compatibility with GCP, OCI, and more object storage providers! Object storages tested for compatibility: - AWS S3 - Google Cloud Storage - OCI Object Storage - Wasabi Hot Cloud Storage - Cloudflare R2 - Backblaze B2 - Storj DCS - IDrive e2 With WinCse, you can access and manage object storage directly from Windows Explorer as if it were local files. If you encounter any bugs, please report them on GitHub. I…

    SandCrab▲152

    Hello HN. SandCrab is an app I originally had the idea for and hacked together over a couple of weekends last October. More recently, I’ve been working on adding new features to it as I use it more as my daily tool to interact with my s3 buckets. A few recent features I am excited about include the ability to search across all of your buckets using wildcards and regular expressions as well as searching and filtering by metadata (e.g. content type, file size, date created, etc). I’ve also added support for configuring and generating presigned urls directly in the app which is nice. The app…

    CallFS – S3-style object store in one Go binary (MIT)▲66

    We started CallFS after yet another late-night “why did the uploads vanish?” incident. Our small team had stitched together rsync, a fragile NFS mount, and an S3 bucket—none of it observable, all of it waiting to bite us. So we wrote a single-process file service in Go that: • Speaks the S3 API (so existing tooling works). • Stores hot data on local disks for speed; cold data can sit in any S3-compatible bucket. • Exposes Prometheus metrics and JSON logs by default, because “what happened?” shouldn’t be guesswork. • Ships as a ~25 MB static binary—no external deps, MIT license. Today it’s…

    Low-cost backup to S3 Glacier Deep Archive▲120

    Hi, most people (hopefully) have local backups. However, when that backup fails, it is good to have a backup stored somewhere off-site. In the old days you would ship physical drives/tapes, which is cumbersome, costly, and slow. With fast upload speeds, it is now possible to upload your data to the cloud. I have found S3 Glacier Deep Archive to be a great solution for this: - It is very cheap ($1/TB/month for US region) - Very reliable (99.999999999% data durability, data spread over 3 Availability Zones) However, usability out of the box is not that great, I'm not aware of…
