The Internet We Didn’t Get

October 2, 2025 by Bryan Cockfield 13 Comments

Collective human consciousness is full of imagined or mythical dream-like utopias, hidden away behind mountains, across or under oceans, hidden in mist, or deep in the jungle. From Atlantis, Avalon, El Dorado, and Shangri-La, we have not stopped imagining these secret, fantastical places. One of these, Xanadu, is actually a real place but has been embellished over the years into a place of legend and myth, and thus became the namesake of an Internet we never got to see like all of those other mystical, hidden places.

The Xanadu project got its start in the 1960s at around the same time the mouse and what we might recognize as a modern computer user interface were created. At its core was hypertext with the ability to link not just other pages but references and files together into one network. It also had version control, rights management, bi-directional links, and a number of additional features that would be revolutionary even today. Another core feature was transclusion, a method for making sure that original authors were compensated when their work was linked. However, Xanadu was hampered by a number of issues including lack of funding, infighting among the project’s contributors, and the development of an almost cult-like devotion to the vision, not unlike some of today’s hype around generative AI. Surprisingly, despite these faults, the project received significant funding from Autodesk, but even with this support the project ultimately failed.

Instead of this robust, bi-directional web imagined as early as the 1960s, the Internet we know of today is the much simpler World Wide Web which has many features of Xanadu we recognize. Not only is it less complex to implement, it famously received institutional backing from CERN immediately rather than stagnating for decades. The article linked above contains a tremendous amount of detail around this story that’s worth checking out. For all its faults and lack of success, though, Xanadu is a interesting image of what the future of the past could have been like if just a few things had shaken out differently, and it will instead remain a mythical place like so many others.

A Love Letter To Internet Relay Chat

September 8, 2025 by Maya Posch 59 Comments

Although kids these days tend to hang out on so-called “Social Media”, Internet Relay Chat (IRC) was first, by decades. IRC is a real-time communication technology that allows people to socialize online in both chat rooms and private chat sessions. In a recent video [The Serial Port] channel dedicates a video to IRC and why all of this makes it into such a great piece of technology, not to mention a great part of recent history. As a decentralized communication protocol, anyone can set up an IRC server and connect multiple servers into networks, with the source code for these servers readily available ever since its inception by a student, and IRC clients are correspondingly very easy to write.

Because of the straightforward protocol, IRC will happily work on even a Commodore 64, while also enabling all kinds of special services (‘bots’) to be implemented. Even better, the very personal nature of individual IRC networks and channels on them provides an environment where people can be anonymous and yet know each other, somewhat like hanging out at a local hackerspace or pub, depending on the channel. In these channels, people can share information, help each other with technical questions, or just goof off.

In this time of Discord, WhatsApp, and other Big Corp-regulated proprietary real-time communication services, it’s nice to pop back on IRC and to be reminded, as it’s put in the video, of a time when the Internet was a place to escape to, not escape from. Although IRC isn’t as popular as it was around 2000, it’s still alive and kicking. We think it will be around until the end days.

Engineering For Slow Internet Even When Not Stuck In Antarctica

September 5, 2025 by Maya Posch 25 Comments

With the days of dial-up and pitiful 2G data connections long behind most of us, it would seem tempting to stop caring about how much data an end-user is expected to suck down that big and wide broadband tube. This is a problem if your respective tube happens to be a thin straw and you’re located in a base somewhere in the Antarctic. Take it from [Paul Coldren], who was stationed at a number of Antarctic research stations as an IT specialist for a total of 14.5 months starting in August of 2022.

As [Paul] describes, the main access to the Internet at these bases is via satellite internet, which effectively are just relay stations. With over a thousand people at a station like McMurdo at certain parts of the season, internet bandwidth is a precious commodity and latency is understandably high.

This low bandwidth scenario led to highly aggravating scenarios, such as when a web app would time out on [Paul] while downloading a 20 MB JavaScript file, simply because things were going too slow. Upon timing out, it would wipe the cache, redirect to an error page and have [Paul] retry and retry to try to squeeze within the timeout window. Instead of just letting the download complete in ~15 minutes, it would take nearly half an hour this way, just so that [Paul] could send a few kB worth of text in a messaging app.

In addition to these artificial timeouts – despite continuing download progress – there’s also the issue of self-updating apps, with a downloader that does not allow you to schedule, pause, resume or do anything else that’d make downloading that massive update somewhat feasible. Another thing here is distributed downloads, such as when hundreds of people at said Antarctic station are all trying to update MacOS simultaneously. Here [Paul] ended up just – painfully and slowly – downloading the entire 12 GB MacOS ISO to distribute it across the station, but a Mac might still try to download a few GB of updates regardless.

End Of The Eternal September, As AOL Discontinues Dial-Up

August 11, 2025 by Jenny List 38 Comments

If you used the internet at home a couple of decades or more ago, you’ll know the characteristic sound of a modem connecting to its dial-up server. That noise is a thing of the past, as we long ago moved to fibre, DSL, or wireless providers that are always on. It’s a surprise then to read that AOL are discontinuing their dial-up service at the end of September this year, in part for the reminder that AOL are still a thing, and for the surprise that in 2025 they still operate a dial-up service.

There was a brief period in which instead of going online via the internet itself, the masses were offered online services through walled gardens of corporate content. Companies such as AOL and Compuserve bombarded consumers with floppies and CD-ROMs containing their software, and even Microsoft dipped a toe in the market with the original MSN service before famously pivoting the whole organisation in favour of the internet in mid 1995. Compuserve was absorbed by AOL, which morphed into the most popular consumer dial-up ISP over the rest of that decade. The dotcom boom saw them snapped up for an exorbitant price by Time Warner, only for the expected bonanza to never arrive, and by 2023 the AOL name was dropped from the parent company’s letterhead. Over the next decade it dwindled into something of an irrelevance, and is now owned by Yahoo! as a content and email portal. This dial-up service seems to have been the last gasp of its role as an ISP.

So the eternal September, so-called because the arrival of AOL users on Usenet felt like an everlasting version of the moment a fresh cadre of undergrads arrived in September, may at least in an AOL sense, finally be over. If you’re one of the estimated 0.2% of Americans still using a dial-up connection don’t despair, because there are a few other ISPs still (just) serving your needs.

Microsoft’s New Agentic Web Protocol Stumbles With Path Traversal Exploit

August 7, 2025 by Maya Posch 11 Comments

If the term ‘NLWeb’ first brought to mind an image of a Dutch internet service provider, you’re probably not alone. What it actually is – or tries to become – is Microsoft’s vision of a parallel internet protocol using which website owners and application developers can integrate whatever LLM-based chatbot they desire. Unfortunately for Microsoft, the NLWeb protocol just suffered its first major security flaw.

The flaw is an absolute doozy, involving a basic path traversal vulnerability that allows an attacker to use appropriately formatted URLs to traverse the filesystem of the remote, LLM-hosting, system to extract keys and other sensitive information. Although Microsoft patched it already, no CVE was assigned, while raising the question of just how many more elementary bugs like this may be lurking in the protocol and associated software.

As for why a website or application owner might be interested in NLWeb, the marketing pitch appears to be as an alternative to integrating a local search function. This way any website or app can have their own ChatGPT-style search functionality that is theoretically restricted to just their website, instead of chatbot-loving customers going to the ChatGPT or equivalent site to ask their questions there.

Even aside from the the strong ‘solution in search of a problem’ vibe, it’s worrying that right from the outset it seems to introduce pretty serious security issues that suggest a lack of real testing, never mind a strong ignorance of the fact that a lack of user input sanitization is the primary cause for widely exploited CVEs. Unknown is whether GitHub Copilot was used to write the affected codebase.

VRML And The Dream Of Bringing 3D To The World Wide Web

August 7, 2025 by Maya Posch 17 Comments

You don’t have to be a Snow Crash or Tron fan to be familiar with the 3D craze that characterized the rise of the Internet and the World Wide Web in particular. From phrases like ‘surfing the information highway’ to sectioning websites as if to represent 3D real-life equivalents or sorting them by virtual streets like Geocities did, there has always been a strong push to make the Internet a more three-dimensional experience.

This is perhaps not so strange considering that we humans are ourselves 3D beings used to interacting in a 3D world. Surely we could make this fancy new ‘Internet’ technology do something more futuristic than connect us to text-based BBSes and serve HTML pages with heavily dithered images?

Enter VRML, the Virtual Reality Modelling Language, whose 3D worlds would surely herald the arrival of a new Internet era. Though neither VRML nor its successor X3D became a hit, they did leave their marks and are arguably the reason why we have technologies like WebGL today.

ProtoWeb: Browsing The Information Superhighway Like It’s 1995

July 17, 2025 by John Elliot V 19 Comments

Feeling nostalgic? Weren’t around in the 90s but wonder what it was like? ProtoWeb has you covered! Over on his YouTube channel [RetroTech Chris] shows you how to browse the web like it’s 1995.

The service that [RetroTech Chris] introduces is on the web over here: protoweb.org. The way it works is that you configure your browser to use the service’s proxy server, then the service will be able to intercept your browsing activity and serve you old content from its cache. Also, for some supported sites, you will see present-day content but presented in the format you would have seen in the 90s. Once you have configured your browser to use the ProtoWeb proxy you can navigate to http://www.inode.com/ where you will find a directory listing of sites which have been archived or emulated within the service.

In his video [RetroTech Chris] actually demos some of the old web browsers running on old hardware, which is a very good recreation of what things were like. If you want the most realistic experience you can even configure ProtoWeb to slow down your network connection to the speed of a 56k dial-up modem. There are some things from the 90s that we miss, but waiting for websites to load isn’t one of them!

We had a look in our own archive to see how far back we here at Hackaday could go, and we found our first post, from September 2004: Radioshack Phone Dialer – Red Box. A red box! Spicy.
