2024-11-13 : An earlier version of this report asserted that consumers with auto-commit enabled could lose data by automatically committing offsets returned by the most recent poll. This claim was based in part on Confluent’s documentation , which states:
Near the beginning of November, nixCraft posted this challenge on Mastodon, daring people to take the No NAT November challenge and disable IPv4 for the month, relying only on IPv6:
As you may, or may not know, I wrote paraLLEl-RDP back in 2020. It aimed at implementing the N64 RDP in Vulkan compute. Lightning fast, and extremely accurate, plus the added support of up-scaling on top. I’m quite happy how it turned out. Of course, the extreme accuracy was due to Angrylion being used as reference…

If you are of a certain vintage, this image is burned indelibly somewhere in your posterior parietal complex: Oh, my old friend. How it’s been a long time. Cultural Significance For the uninitiated, what are we looking at? Could it be the Moiré Error from Doom? Well, no. You are looking at (part of) the boot up screen…

While deploying Precision Time Protocol (PTP) at Meta, we’ve developed a simplified version of the protocol (Simple Precision Time Protocol – SPTP), that can offer the same level of clock syn…
The demo shows that even though the behavior appears similar, TCP connections leak when using the io_uring driver but not with the epoll driver. I've also tested this across various io_uring runtimes, and it turns out to be a common issue across all of them.
Intel released the powerful Pentium processor in 1993, a chip to "separate the really power-hungry folks from ordinary mortals." The origin...
From the Zed Blog: In this episode of Zed Decoded, Thorsten and Antonio explore how we use async Rust in the Zed code base to ensure perfect cooperation with macOS to always maintain responsiveness and high-performance.

No clustering algorithm is perfect and you must make a trade-off.
I don’t want to post yet another anti-systemd rant, but I think the ubiquity of systemd could eventually create real problems for embedded Linux. I just wish I knew what to do about it.

In a previous article, I explained how I set up a TFT LCD screen on my Raspberry Pi. Because I had been previously using my Pi as a headless server, I hadn’t installed a desktop environment. I wanted to add a lightweight heads-up display to the server, and I wanted a graphical application that could operate without X…
How does Linux move from an awake machine to a hibernating one? How does it then manage to restore all state? These questions led me to read way too much C in trying to figure out how this particular hardware/software boundary is navigated.

I bought a Surface Pro 4 in 2016. It has an Intel Core m3-6Y30 CPU and 4GB memory. The spec is not that impressive even compared to an average laptop released years earlier. On the other hand, the form factor is very attractive to me: at a very low price, you get a tablet with a beautiful HiDPI 2k screen, a pressure…
Introduction When modeling a Postgres database, you probably don’t give much thought to the order of columns in your tables. After all, it seems like the kind of thing that wouldn’t affect storage or performance. But what if I told you that simply reordering your columns could reduce the size of your tables and…
Understand .NET 9.0 LINQ performance improvements, faster iterator and the usage of Span
A few months ago, I got given a laptop with a very interesting condition. The BIOS setup menu was supposedly inaccessible, and nothing apart from the default boot option works. Time to investigate to see what is actually happening and what we can do about it.
Combining prefix search with repeated search, to accommodate multiple styles.
I tried everything but couldn’t turn this Raspberry Pi 5 into the World’s Fastest Pi 5. Unfortunately, we can’t quite claim that title.
What is a deterministic hypervisor and why do we need one anyhow?
