I guess you have all heard about the growing problem of AI companies trying to aggressively collect whatever data they can get their hands on to train their models. This has caused an explosive surge in web crawlers relentlessly hitting servers big and small. But who runs these crawlers? Turns out — it could be you!
Inside PgDog's wire protocol handling: parsing simple and extended messages, using pg_query for AST inspection, and routing queries via the Postgres hash partition function.
I came to the NAB (National Association of Broadcasters) show this year with my Dad to learn more about time in broadcast and live production. I was expecting to learn more about grandmaster clocks, AV sync, timing in protocols like Dante, Livewire, AES67, and more—and I have. But then on the first day here I found…
Websockets are powerful tools that have become a fan-favorite for building realtime applications, but you might be using them for all the wrong reasons. Let's explore the pitfalls of websockets and how we can use plain old HTTP to get the same job done.
I’ve found a way to configure private, custom domains for web-apps I have running on my computer. So instead of having to remember and type “localhost:4333”, I can simply navigate to “appname.localhost”. I love it!
Explore A2A, Google's new open protocol empowering developers to build interoperable AI solutions.
Spoiler: it doesn’t. But it should.
Matrix, the open protocol for secure decentralised communications
Learning how the IMAP protocol actually works
tl;dr: I set up an open source Time Pi project to build a stratum 1 PTP and NTP timeserver using a Raspberry Pi. Time is important to modern society, and most of us have a clock on our wrist that's more accurate than at any time in human history. But highly precise time is important in many industries, especially…
This post investigates how we got from Wi-Fi Direct to AWDL to Wi-Fi Aware, what makes Wi-Fi Aware technically superior, and why this shift unlocks true cross-platform peer-to-peer connectivity for developers.
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
Turn-Taking is a big challenge AI Voice Agents are rapidly evolving, powering critical use-cases such as customer support automation, virtual assistants, gaming, and remote collaboration platforms. For these voice-driven interactions to feel natural and practical, the underlying audio pipeline must be resilient to…
The Internet Slum
Taara is now an independent company with a mission to bring high-speed, affordable and abundant connectivity to people everywhere using beams of light.
The Registration Data Access Protocol (RDAP) is the successor to WHOIS, which is being sunsetted on 28 January 2025.
The ESP32 is a popular microcontroller to use for do-it-yourself home automation, sensors, and a variety of other bits and bobs that you might want to take care of around the house. It’s the successor to the venerable ESP8266 which has found its way into many of our WiFi connected devices (seriously, open up a device…
HTTP/3 has been in development since at least 2016, while QUIC (the protocol beneath it) was first introduced by Google way back in 2013. Both are now...
Towards the end of last year, we learned that a group (allegedly affiliated with the Chinese government, referred to as “Salt Typhoon”) breached T-Mobile and other telecommunications co…
We are proud to share the next step in our journey towards tech independence: building our very own search index!
A “distrust” is when a certification authority (CA) that issues HTTPS certificates to websites is removed from a root store because it is no longer trusted to issue certificates. This means certificates issued by that CA will be treated as invalid, likely causing certificate error interstitials in any browser that…
It's probably old news for most, but I've recently started using Tailscale and wanted to share my experience with it.
Chrome Returns 206 when the Server Returns 403 Postmortem It is a feature not a bug! I got detailed explanation from chrome developers which is very helpful. You may find the complete response in the bug ticket. Also this blog post draws a lot of attention after I post it on Hackers News. You may find comments here…
This is a story of the complexities of cellular connectivity, the perils of closed ecosystems, and how to debug what you cannot see.
I want to write a post about Pitchfork, explaining where it comes from, why it is like it is, and how I see its future. But before I can get to that, I think I need to share my mental model on a few things, in this case, HTTP/2.
Matrix, the open protocol for secure decentralised communications
By examining the limits of reasonable user behavior and embracing imperfection for users who go beyond it, we can continue to provide service that meets the expectations of users without sacrificing scalability of the system.
Yesterday I read this toot (German) over on mastodon which starts with “IPv6 is hard.” No it’s not. It’s different. I ran across this multiple times: There is an A and an AAAA-record for a FQDN, but the web server is only reachable via IPv4. You can easily test this with curl $ curl -4 https://github.com -o /dev/null…
If you have ever tried communicating with a device on a private network, you may have encountered Network Address Translation (NAT). Because the number of connected devices has long outpaced the number of unique addresses in the IPv4 address space, public IP addresses have to be shared between devices. This introduces…
