The interesting part about the enterprise quality disk misinformation is how so wrong it is. The core idea of ZFS was to detect issues when those drives or their drivers are faulty. And this was more happening with cheap non-enterprise disk

Its really easy for them, and this also in line how they would operate: Add a new Airtag v2 protocol to the next iPhone and sell new Airtags only using that protocol. Why should you buy them? They could have different improvements you would

The problem is typically day 1000 problems: The database broke, nobody really understands all the stuff and dependencies by the kubernetes helm chart and still you have to fix it. Downtime is now calculated in days and not hours.

Letting a static analyzer do these checks is a sane approach! The runtime detection of code files is really weird and would fail with bundling etc.

The most important part is understanding that downtimes are not a problem! Cloudflare is again down and your service is not available for an hour? You cant do anything. And nobody unsubscribes. Most downtimes are because another service is

The problem is that these type of very much needed but boring new features don‘t grant you a promotion. But if you work on a GenAI product right now the odds are in your favour.

Oh totally forgot to mention: There‘s also an API to skip the manual steps needed on the website. So I plan on integrating it into database tools like DataGrip etc.

LightVM is stating a VM creation of 2.3ms while Firecracker states 125ms of time from VM creation to a working user space. So this comparing apples and oranges.

But then also monitoring gets harder. With containers you could see (and monitor) all those processes running in container easy on the host. With VMs? You now need a way to get data from within the VM which in most lightweight VM implementa

Most probably because ZFS still has the most extensive data correctness guarantess of all filesystems on Linux. Yes, bcachefs will have checksums too but it it is still in beta.

They‘ve stated clearly that you pay the same. Its just calculating stuff differently that you can now remove a dedicated machine mid-month and get the remaining time‘s money back. Which wasnt the case until now.

And when you have performance issues you still need a DBA. Because RDS only runs your database. It is up to you to make it fast.

Thats because EBS is a network block device and not a network filesystem - that would be EFS. And with network block devices you get the same perf and better compared to EBS.

Ordering that amount of amount of servers takes about one hour with hetzner. If you truly want a complete rack on your own maybe a few days as they have to do it manually. Most companies don‘t need to scale up full racks in seconds. Heck, e

Postgres Rust extensions is a completely different topic than rewriting PG in Rust. The problem is that a crash in any extension will take down the full PG worker. So you can havoc the robustness of your PG database with any extension. But

Exactly. I‘ve seen it sold that anyone has less books to carry and they could do more digital stuff - but nobody had any real plans. In the end one of ten text books was a PDF and you didn‘t gain anything. Its worse, now your textbook can h

They are only doing unmetered DDoS for HTTP traffic - for websites. File storage etc. is not allowed. And git falls into that realm.

Any of the capabilities needed by the exploits is in linux only available to root users. And are now granted to a container. So these ”escapes“ are basically giving a container full access to the host and using that. None of them are enable
