tock VS Killed by Google

Hi! This is Daniel from OxidOS Automotive (stating this for disclaimer purposes).

Yes, our OS is based on TockOS, and our CEO (Alex Radovici) is #7 in the contributors list (https://github.com/tock/tock/graphs/contributors), with other colleagues contributing in the past years.

I'm definitely not the best person to answer this, but honestly it's not bad. Here's an example of a moderately complex peripheral, the cortex-m MPU, and how one rust OS handles it:

https://github.com/tock/tock/blob/3a0527d586702b8ae8cb242391...

Reads and writes turn into volatile reads, so everything works out under the hood. You get the benefits of everything having good names, declared sizes, and proper typing on your register accesses. You can extend that to bit accesses as well.

Rust still has a few areas it isn't competitive in, like your hyper limited or obscure chips (e.g. 8051s, XAP), mature tooling around formal methods, and a certification story for safety critical code. People are working on these latter two issues (e.g. ferrocene) and supposedly very close to public delivery, but you know how slow the industry is to adopt new things even then.

There's Tock (https://www.tockos.org/), which is written in Rust (with sprinkles of assembly).

Yeah, and I like I mentioned in the earlier comment, omitting the frame pointer reduces code size by 10% on RISC-V targets, which is huge when dealing with embedded flash: https://github.com/tock/tock/pull/1660

Tock is an excellent embedded OS written in Rust and has some good industrial support. I think Tock gets a lot of stuff right and I highly recommend some of the talks the developers gave on it.

Unfortunately, it increases the code size by 10%. I was looking into this just last week, and can confirm that it's still a problem on the latest version of Rust nightly: https://github.com/tock/tock/pull/1660

I wish we could have frame pointers, because they would make working in embedded land so much easier and more reliable, but a 10% increase in code size just isn't worth it.

TockOS was the first rust RTOS I found. Coincidentally, it has had support for the esp32c3 for over a year now.

I was already starting to feel a little cornered in the whole Google ecosystem and a bit limited with stuff like backups, vendor lock in, etc. (and you always have the obvious hanging over your head) and ultimately, I think I just find the mental model of a SQL database more intuitive compared to a NoSQL database. So I thought to myself; "the longer I leave it, the harder it'll be to make the switch".

Their reputation is deserved. Google domains was killed only last year!

And this isn't even the first time I've been burned by Google's decisions. If you're familiar at all with the Google Graveyard, you'll know that Google has a long history of killing off products and services that people have come to rely on. This has happened to me a number of times, in both a personal and professional capacity, and frankly it's getting old.

Just because Google has a couple of decent services that you're willing to pay for doesn't detract from the fact that most of their products have a worse life expectancy than a victorian child in the 1800s. https://killedbygoogle.com

They ruined every single opportunity to be more than an advertising company since Orkut. With scrapped attempts, starts and lack of intention for most of the 2010s to even during the early half of the Pixel Era, they seemingly haven't learnt to stick to something and iterate on it well.

And the fact that over 50% of their revenues come from search and by extension, advertising.

The fact' that til this day, they still haven't evolved from the "throwing shit at the wall then at the fan" strat which explains how they have fumbled so much so quickly.

Yeah. The Google Graveyard really shows how far this can go.

The punchline is that in addition to hundreds of failed hobby projects, their stock is doing great. Monopoly power is a helluva drug.

To me Gemini is just sort of generic and uninteresting. There has to be hundreds or thousands of products and companies based on the name "Gemini" - "Bard" was at least interesting, different and distinct.

I've no idea about the quality of the product itself, I have never had a reason to use it. It's long past cliché now but I wouldn't get too attached to a Google product that is definitely costing a lot of money but which has no clear pathway to turning a profit. I think they will keep it ticking over until the hype train moves on from Chatbots/LLMs, and then it'll join the Google Graveyard @ https://killedbygoogle.com

We're not talking about reliability, we're talking about Google's penchant for killing established products that people use. https://killedbygoogle.com
