Switched another service from JSON to YAJBE.
Just a few lines changed to replace JSON stringify/parse.

My unofficial Ubuntu support for sched-ext is now documented in the official sched-ext README 😊https://t.co/6WQdCbk3g5 #linux #kernel #sched_ext #Ubuntu

@AndresFreundTec FUSE was my go to tool to do that. in few lines of code you can implement a file system wrapper and add the behaviour you want. delays, failures, fake super large files and so on

a Set of indexes, using ADD bitmap = [i]
or something else?

You can write C++/Rust/Go/Java code that is much slower than Python. So please use Python if it is fast enough for your needs. Do not assume that "written in Rust/C/C++" means "fast and efficient". It does not.

[Matteo Bertozzi @th30z]

@kellabyte How do you ensure the requests (in the sequence) are going to the same server/thread? We always assume that each request is going to a different server and they are all out of order. We send (ReqId, Index) and we keep a bitmap of the received parts. Then we execute. Alternatives?

I saw this one on a forum for artists. Applies maybe even more to us, I would think. https://t.co/SFYOzszn3g

Enjoy our latest blog:
Building a control plane for Infra SaaS is not rocket science - but it does have quite a few gotcha. In this blog post we tried to map out the major challenges a team will encounter when building a control plane for Infra SaaS. https://t.co/COTp3I1V2e

[Gwen (Chen) Shapira @gwenshap]

Our first blog post! In this blog, we talk about what is the motivation behind Infrastructure SaaS architecture, what are the requirements of a control plane, the end-to-end architecture, and the challenging problems in building it.

Some tech: "We've reached the limits of #PostgreSQL"
Me: "Let me rephrase. Your bad design data model and badly designed application including several well-known antipatterns do not work as your twisted brain expected."

I'll uphold @PostgreSQL with my last breath!

[Matteo Bertozzi @th30z]

@gwenshap Where are the Aurora I/O requests costs? that one is always the highest on my list, and unfortunately there is no way to see which db is costing more, you can only see the I/O for each cluster

[Matteo Bertozzi @th30z]

@gwenshap sqlite varint are much more interesting https://t.co/wY43uCbEjm
