That brings up another point. Should the kernel standardize on unsigned scalars completely? How many legitimate use cases are there to use signed scalars in the kernel?
Earlier quoted context omitted.
The front-line support is the same as anywhere else. But Google Cloud has really really good second and third line support, if the first tier can't figure it out. And in many cases, it'll get escalated directly to the implementing engineers. In my experience, Google Cloud is better than most organizations about escalating hard issues up to the chain. Admittedly, this happened at a company with substantial spend, and…
How much is “substantial” for gcp to get decent support? Tens of millions/y certainly wasn’t cutting it...
I'm not an expert with AWS or Google Cloud, so I'm interested in knowing: What "level" of customer or SLA do you have to be to get a certain quantity or guarantee of support and troubleshooting? Or is it that if even a free-tier customer points out something that is fundamentally a problem, it will receive attention by certain solutions engineers? Are there $ spending, 20 x (c3.4x.large), or I-pay-you-for-certain-upt…
Here you go: https://cloud.google.com/support#support-plans $250/month/dev is the minimal for phone calls on technical issues, $150k + 4% of GCP spend for 'come running' support. There're more details here https://cloud.google.com/support/docs/procedures#additional_... though they use the old names for the support tiers.
This is a fun debugging story, but is a great example why servers should be cattle not pets. Having trouble with a VM? Blow it up and get a fresh one. Still having trouble? The provisioning steps are codified, you can walk through them and find the one that causes the issue.
Cattle is a threshold, but when the same problem keeps coming up it's time to call the vet. http://rachelbythebay.com/w/ has many good examples of this, some submitted and voted up here.
Google support is basically non existent for customers even spending like 5-10K a month on their platform. Even questions you raise on their Reddit sub go unnoticed. They don't have bunch of people actively trying to solve their customers problem. That said the only time my problems were actually listed to were from BigQuery team. Other than this, I don't think it's possible to get any explanation on a feature from a…
We rarely have to do so, but whenever we did, they went out of their way to figure it out.
YMMV, I guess?

What "dev" or "user" means here ...for example if I run a server serving some HTTP API.
For small to medium sized businesses, that number is probably 1.
Long-term solution - Use rust
Can you expand on your answer. How does Rust resolve this issue? Does it solve by disallowing type casts thereby preventing overflow when the number becomes negative?
So, in Rust, overflow panics in debug builds, but does wrap around in release builds. So, it is possible this bug would have been caught in testing, but if it wasn't, it still would have slipped into production.
However, that being said, Rust does not do implicit casting between numeric types. So it's very likely that this code would not have compiled in the first place, though I haven't examined it super closely. At that time, the person would have had to cast it, and so the end result would have been roughly the same.

Using unsigned does not generally fix overflow flaws. It just moves the threshold.

If you're 5 people at a dentist office with GSuite, that may be a different story. That's always a problem when small entities buy direct -- that's why VARs exist to provide more handholding for smaller orgs.
I've managed some pretty significant vendor relationships -- if you think they are the worst from a support POV, you're young or exceptionally lucky!
