tamago VS hn-search

There's two major production-ready Go-based operating system(-ish) projects:

- Google's gVisor[1] (a re-implementation of a significant subset of the Linux syscall ABI for isolation, also mentioned in the article)

- USBArmory's Tamago[2] (a single-threaded bare-metal Go runtime for SOCs)

Both of these are security-focused with a clear trade off: sacrifice some performance for memory safe and excellent readability (and auditability). I feel like that's the sweet spot for low-level Go - projects that need memory safety but would rather trade some performance for simplicity.

Of course it can, there are companies shipping products written in bare metal Go.

For comparison, what are the differences in goals and approach with Tamago? https://github.com/usbarmory/tamago

I've been keeping an eye on TinyGo (Go compiler that targets microcontrollers and uses LLVM) and also TamaGo (allows you to run Go on bare metal, without any C dependency).

If you want to go deeper, there is also bare-metal Go runtime for rpi (among others): https://github.com/f-secure-foundry/tamago

Tone is not needed.

For TamaGo, it seems to allow developers run their application, not build an OS on the hardware. But I have not played with it, you are right.

> TamaGo is a framework that enables compilation and execution of unencumbered Go applications on bare metal

The environment does not seem to allow building a generic operating system [1]. F-Secure ported the runtime itself to boot natively. But please correct me.

> There is no thread support

The environment you run in is specifically curated for Go applications, such as the memory layout. I'd call this an "appliance" rather than enabling Go to be used for full-fledged generic operating system implementations.

Ok, but please don't post unsubstantive comments to Hacker News.

I understand the reason for repeating these sentiments—it's the same reason why they get upvoted to the top of threads*—but repetition of this kind is what we're most trying to avoid here.

I was looking for it in the guidelines. There are a couple of conventions for postings. Consider a bit of prior examples: [https://hn.algolia.com/?q=show+hn]

yeah there are only three stories coming up from the site search

https://hn.algolia.com/?q=postgres+clustering

only one is semanthically correct, the other pick up the wrong version of clustering (i.e. k-means instead of multi master writes)

but yeah if one doesn't test the hard cases, how does one know it preserves semantics :D

Submitters: If you want to say what you think is important about an article, that's fine, but do it by adding a comment to the thread. Then your view will be on a level playing field with everyone else's: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so...
