FYI, I might be missing something but I think your billing system might not be working well - I'm not seeing any indication in the UI that my usage is being deducted from the $5 of free credits.

Works much better now! Got 103.9 tok/s, not quite 200 - but still amazing! Thanks for sharing

I tried in your playground and got 14.2 tok/s?

This is a boggling level of disdain for customer security - even putting aside the insanely low levels of data security, it's mind boggling that the website remained up for months after the disclosure, and that even after being taken down the vulnerability remained open.

Great post!

In case you ever decide to return to AWS, its Cost Explorer is far from perfect but it can show you where your expenses are coming from, especially if your costs are pennies. In the last re:invent they even released daily granularity when grouping by resources (https://aws.amazon.com/blogs/aws-cloud-financial-management/...).

Yeah, I see what you mean - that'd indeed render this method ineffective. Like you said I'm sure this would bother a lot of customers, but it's not a completely unrealistic overhaul of S3 pricing.

That being said, that'd be sort of "mean" of AWS to do - the data is already replicated across AZs whether you pay for it or not because of how S3 works.

Thanks for the feedback! I don't think it's nitpicking, you're right that it's misleadingly phrased - in fact, the only S3 costs I observed weren't storage at all, but rather the API calls.

I updated the phrasing.

I'm not sure how this could be removed - the fundamentals behind it are basic building blocks of S3.

Maybe raising the cost of transient storage? e.g. If you have to pay for a minimum of a day's storage - but even if that was the case this would still be cost-effective, and at any rate it seems very unnatural for AWS to charge on such granularity.

+ I would guess that S3 is orders of magnitude more profitable for AWS than cross-AZ charges, so I'm not sure they'd consider it a loss-leader.

This is great for saving on S3 storage costs!

But in the context of data transfer costs, this would actually increase the costs, because there's a small surcharge for Intelligent Tiering - and the only relevant storage class for sidestepping data transfer costs is standard storage (because it's the only one with free download), so Intelligent Tiering won't provide value.

I understand the sentiment behind your frustration - but it's worth noting that these support tickets are usually answered really quickly.

Specifically as it relates to Lambdas there's solid rationale behind these limits, but I agree that in many other cases the limits seem arbitrary and annoying.

New comment by danielklnstein in "Six Great Features with the Upcoming Linux 6.6 Kernel"

danielklnstein — Sat, 28 Oct 2023 16:30:30 +0000

As another comment explains - the vast majority of drivers are not compiled as part of a standard Linux distribution.

If you're asking why so many drivers are included in Linux's mainline repository and not maintained off-tree - the major advantage of being upstreamed is that changes to the kernel have to take your driver into account as well. e.g. anyone who changes any APIs will have to update your driver as well.

Moreover, being upstreamed certifies that your driver has gone through a non-trivial review process to be merged into the mainline and is an indication of quality/stability.
