How to manage constant, chaotic change

Platform engineering should reduce friction, enable agility and make technology a seamless enabler, not a burden. But how do we know if it’s working?

Find Open Source Software Projects from NASA.

One thing about developing satellites, spacecraft, rovers and kin is that they have a big overlap in terms of functionality. From communication, to handling sensors, propulsion, managing data stora…

“I used to memorize every AWS acronym and service. But did I really get it?” — Guilty as charged.

Functional requirements = what the system should do

IMO this is very doable whether Kubo can do this very efficiently or whether it’d be more efficient to leverage existing IPFS library code (e.g. the Go code that goes into Kubo or some of the alternatives in JS or Rust). There are already a number of IPFS implementations out there so making a new one out of similar parts doesn’t seem like a stretch. As you mentioned the strawman version of this is pretty easy already you can run a kubo node and use a local (or public) HTTP gateway and call it ...

A new torrent site called Torrent Paradise uses a decentralized platform that can’t be taken down by the authorities,.

tl;dr: Get BitTorrent clients to download and seed over both BT and IPFS, while reducing redundancy. We can use the same techniques to deduplicate or revive dead CIDs in general. Feedback appreciated. For background, GetRight style WebSeed links (BEP 19) are just regular web links that a BitTorrent client can download from: Many websites that list a BitTorrent download also provide a HTTP or FTP URL for the same file. The files are identical. A WebSeeding BitTorrent client can download from ei...

Learn the basics of IP multicasting. How it works and how it is used. How multicasting differs from broadcasting.

As network demands grew in the late 20th century for higher speed and more reliable transmission of multimedia data, Asynchronous Transfer Mode (ATM)

Before Ethernet became the dominant local area network (LAN) technology, Token Ring was a widely used alternative. Developed by IBM in the 1980s and

Ethernet is the most widely used technology in Local Area Networks (LANs) today. Known for its speed, scalability, and cost-effectiveness, Ethernet forms

Modern networking infrastructures are built on specific architectural models that define how devices are interconnected. These architectures determine the

Explore when to use DNS load balancing and the key conditions for its effectiveness in managing network traffic.

- Everything I know and learned about running and maintaining Open Source projects for three decades. For several years now, I have had a blog post series in mind to describe something about what people could expect to happen in Open Source projects. I had a few already half-started blog post drafts for some sub … Continue reading Uncurled →
