Dial-Up Is Still, Just Barely, A Thing

March 6, 2024 by 86 Comments

In an era dominated by broadband and wireless cellular networks, it might come as a surprise to many that dial-up internet services still exist in the United States. This persistence is not a mere relic of nostalgia — but a testament to the diverse and uneven nature of internet infrastructure across the country.

Yes, dial-up internet, with those screechy, crackly tones, remains a useful tool in areas where modern, high-speed internet services are either unaffordable or unavailable. Subscriber numbers are tiny, but some plough on and access the Internet by the old ways, not the new.

Replacement PCB Replicates Early 80s Modem

February 21, 2024 by 27 Comments

It’s certainly been a few decades, but plenty of us remember a time before widespread access to broadband internet, when connections were generally made over phone lines using acoustic modems. In the 90s these could connect you to AOL and Napster well enough, but in the early 80s the speeds were barely enough to read text as it loaded. A company called Hayes set out to change this with some of the first useful, widely-available modems for the PCs at the time. While they couldn’t keep up with the changing times there’s still a retro community that has these antiques, and to modernize it a bit this drop-in replacement for the PCBs replicates these old modems almost exactly.

The new PCB is equipped with everything needed to get a retro computer online again, including all the ports to connect a computer without any further modifications. It houses a few modern upgrades beyond its on-board processors, though. Rather than needing an actual acoustic coupled phone, this one has an ESP32 which gives it wireless capability. But the replacement PCB maintains the look and feel of the original hardware by replicating the red status LEDs at the front, fitting into the original Hayes cases with no modifications needed at all, and even includes a small speaker through which it can replicate the various tones, handshakes, and other audio cues that those of us nostalgic for this new online era remember quite well.

For those looking for a retro feel without the hassle of getting antique networking equipment functional again, this type of upgrade that preserves the essence of the original hardware is an excellent way of keeping retro computers functional on modern networking equipment. But if you absolutely must get the networking equipment exactly right down to the last patch cable, you might end up having to build your own ISP from scratch.

FLOSS Weekly Episode 770: 10% More Internet

February 14, 2024 by 7 Comments

This week, Jonathan Bennett and Doc Searls talk with David Taht about the state of the Internet and, specifically, IPv4 exhaustion. We’re running out of IPv4 addresses! But we’ve been running out for something like ten years now. What gives? And why are nearly 20% of the world’s IPv4 addresses sitting unused? David has a hack that would give the world 10% more Internet, but Amazon might have something to say about it.

There’s even more, like Kessler Syndrome, some musing on what the Interplanetary Internet will look like, the worth of real paper books, and a long-term bet for some IPv4 addresses to come to fruition in 2038.

The First Search Engines, Built By Librarians

June 11, 2023 by 14 Comments

Before the Internet became the advertisement generator we know and love today, interspersed with interesting information here and there, it was originally a network of computers largely among various universities. This was even before the world-wide web and HTML which means that the people using these proto-networks, mostly researchers and other academics, had to build things we might take for granted from the ground up. One of those was one of the first search engines, built by the librarians who were cataloging all of the research in their universities, and using their relatively primitive computer networks to store and retrieve all of this information.

This search engine was called SUPARS, the Syracuse University Psychological Abstracts Retrieval Service. It was originally built for psychology research papers, and perhaps unsurprisingly the psychologists at the university also used this new system as the basis for understanding how humans would interact with computers. This was the 1970s after all, and most people had never used a computer, so documenting how they used search engine led to some important breakthroughs in the way we think about the best ways of designing systems like these.

The search engine was technically revolutionary for the time as well. It was among the first to allow text to be searched within documents and saved previous searches for users and researchers to access and learn from. The experiment was driven by the need to support researchers in a future where reference librarians would need assistance dealing with more and more information in their libraries, and it highlighted the challenges of vocabulary control in free-text searching.

The visionaries behind SUPARS recognized the changing landscape of research and designed for the future that would rely on networked computer systems. Their contributions expanded the understanding of how technology could shape human communication and effectiveness, and while they might not have imagined the world we are currently in, they certainly paved the way for the advances that led to its widespread adoption even outside a university setting. There were some false starts along that path, though.

A Handy Guide To The Humble BBS

November 29, 2022 by 32 Comments

Some of us who’ve been online since the early days fondly remember the web of yore — with its flashing banners, wildly distracting backgrounds, and automatic side-scrolling text. But there was a time before the worldwide web and the Internet as we recognize it today, and the way of communicating in this before-time was through Bulletin Board Systems, or BBS. There are still some who can cite this deep magic today, and this page is perhaps the definitive guide to this style of retrocomputing.

This how-to is managed by [Blake.Patterson] who is using a wide variety of antique machines and some modern hardware in order to access the BBSes still in service. He notes in this guide that it’s possible to use telnet and a modern computer to access them, but using something like an Amiga or Atari will give you the full experience. There are some tools that convert the telephone modem signals from that original hardware to something that modern networking equipment can understand, and while the experience might be slightly faster as a result, it does seem to preserve the nostalgia factor quite well.

For those looking for more specific guides, we’ve featured [Blake]’s work a few times in the past, once with an antique Epson PX-8 laptop and again with a modern ESP8266. It doesn’t take much computing power to get connected to these old services, so grab whatever you can and start BBSing!

A Collection Of Websites That Look Like Desktops

October 27, 2022 by 15 Comments

Web design has come a long way since those halcyon days of Web 1.0. There are plenty of rules about how to make a clean and efficient website, but sometimes it’s more fun to throw them out and just be creative instead. In that vein, [Simone] has curated a wonderful collection of websites that emulate the computer desktop experience online.

The collection’s website very much fits this theme. Upon visiting, an Award BIOS screen flashes up. From there, we get a Windows 95-like interface full of links to other sites that emulate a computer desktop layout. There’s even a 3D screensaver that pops up if you mouse away for too long.

There’s Browso.app, which semi-accurately tells you information about your computer in a theme reminiscent of MacOS 9. Meanwhile, clicking on “It Is As if You Were Doing Work” will take you to a weird game that’s compelling in its replication of office banality. Nightwave Plaza offers exquisite vaporwave vibes, while others simply intend to faithfully recreate various OSes in a browser window.

It’s a fun collection of websites that go from the weirdly afamiliar to downright impressive recreations of former realities. It’s certainly fun to click around for a while and see what’s out there. We do love some good web ephemera around these parts!

Bufferbloat, The Internet, And How To Fix It

August 18, 2022 by 48 Comments

There’s a dreaded disease that’s plagued Internet Service Providers for years. OK, there’s probably several diseases, but today we’re talking about bufferbloat. What it is, how to test for it, and finally what you can do about it. Oh, and a huge shout-out to all the folks working on this problem. Many programmers and engineers, like Vint Cerf, Dave Taht, Jim Gettys, and many more have cracked this nut for our collective benefit.

When your computer sends a TCP/IP packet to another host on the Internet, that packet routes through your computer, through the network card, through a switch, through your router, through an ISP modem, through a couple ISP routers, and then finally through some very large routers on its way to the datacenter. Or maybe through that convoluted chain of devices in reverse, to arrive at another desktop. It’s amazing that the whole thing works at all, really. Each of those hops represents another place for things to go wrong. And if something really goes wrong, you know it right away. Pages suddenly won’t load. Your VoIP calls get cut off, or have drop-outs. It’s pretty easy to spot a broken connection, even if finding and fixing it isn’t so trivial.

That’s an obvious problem. What if you have a non-obvious problem? Sites load, but just a little slower than it seems like they used to. You know how to use a command line, so you try a ping test. Huh, 15.0 ms off to Google.com. Let it run for a hundred packets, and essentially no packet loss. But something’s just not right. When someone else is streaming a movie, or a machine is pushing a backup up to a remote server, it all falls apart. That’s bufferbloat, and it’s actually really easy to do a simple test to detect it. Run a speed test, and run a ping test while your connection is being saturated. If your latency under load goes through the roof, you likely have bufferbloat. There are even a few of the big speed test sites that now offer bufferbloat tests. But first, some history. Continue reading “Bufferbloat, The Internet, And How To Fix It” →
