The Gopher Revival Is Upon Us

December 29, 2023 by Jenny List 39 Comments

A maxim for anyone writing a web page in the mid 1990s was that it was good practice to bring the whole thing (including graphics) in at around 30 kB in size. It was a time when the protocol still had some pretence of efficient information delivery, when information was self-published, before huge corporations brought everything under their umbrellas.

Recently, this idea of the small web has been experiencing something of a quiet comeback. [Serge Zaitsev]’s essay takes us back to a time before the Internet as we know it was born, and reminds us of a few protocols that have fallen by the wayside. Finger or Gopher, both things we remember from our student days, but neither of which was a match for the browser.

All is not lost though, because the Gemini protocol is a more modern take on minimalist Internet information sharing. It’s something like the web, but intentionally without the layer upon layer of extraneous stuff, and it’s been slowly gathering some steam. Every time we look at its software list it becomes more extensive, and we live in hope that it might catch on for use with internet-connected microcontroller-based computing. The essay is a reminder that the internet doesn’t have to be the web, and doesn’t have to be bloated either.

Browsing The WWW On A 1980s IBM PC Using MicroWeb

November 6, 2023 by Maya Posch 12 Comments

Do you ever sit at your 1981 vintage IBM PC and get the urge to pop onto that newfangled ‘WWW’ to stay up to date on all the goings-on in the world? Fret not, because [Al’s Geek Lab] has you covered with a new video (also embedded below), which you will unfortunately have to watch on a device that was made at the very least in the late 1990s. What makes this feat possible is a miniscule web browser called MicroWeb, created by [jhhoward], that will happily run on an 8088 CPU or compatible, without requiring any fiddling with EMS or similar RAM extensions.

Of course, you do need to have some kind of way to actually connect to the World Wide Web, which can be an ISA network expansion card, EtherSlip, as well as using a thin client as a network bridge with some Serial Line Interface Protocol (SLIP) action. Of course, some limitations exist, in that graphics and CSS are not rendered, JavaScript is totally off-limits, and for HTTPS-only websites a workaround like retro-proxy has to be used as TLS encryption would be completely unusable on a couple-of-MHz-CPU.

There’s also the FrogFind service, which will helpfully strip down a target website down to its barest HTML essentials, along with the 68K News site that strips down Google News, so that you can enjoy the WWW in its text-based glory as it would have looked in the early 1980s.

Is A Pigeon Faster Than The Internet?

September 2, 2023 by Chris Lott 46 Comments

[Jeff Geerling]’s latest project is for the birds — literally. Even though he has a brand new high-speed fiber optic internet connection, online backups of YouTube video projects still take hours. He decided to see if the conclusions from a 2009 in South Africa study still hold true today — that using carrier pigeons to send files can be faster than the internet. [Jeff] sets up an experiment to send 3 TB of data by homing pigeon a distance of one mile to establish a baseline. Next, [Jeff] sends the same 3 TB of data over the internet, and donning the cap of honorary pigeon, simultaneously embarks on a journey by air to his off-site backup service in Nova Scotia, Canada.

Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.

[Jeff] points out that you also have to consider the transfer time of your files onto and from the pigeon-suitable memory cards. He jumped through several hoops to minimize that, but it still consumed 2-1/2 hours total. Trying to keep the comparison fair, he also spent a couple days optimizing his internet connection to eek out the best possible speed. Continue reading “Is A Pigeon Faster Than The Internet?” →

Stay Online When The Power Goes Out With This Fiber Modem UPS Hack

August 30, 2023 by Lewin Day 22 Comments

It’s desirable to have your Internet connection up at all times, particularly as it can take some time to get back online if you have a power interruption or similar. [Brink] had some issues with the power supply in their apartment, so they set about whipping up a backup power solution to keep their Verizon ONT fiber modem up and running in such events.

The I-211M-L modem is actually equipped to run on backup battery power, but by default, it will only keep phone service online. Data and television services are normally switched off when the mains supply goes out. Thankfully, a minor mod to the unit’s power cable shared by [mousehunt] enables it to keep data services online when running on backup power. Grounding a bunch of pins with a strip of foil is enough to do the job.

From there, it’s a simple matter of hooking up a stout 12 V battery to the modem via its backup power connector. [Brink] specified a nifty 12 V rechargeable lithium ion pack for the job, which is sold as a portable power unit for running LED strips. Some neat cabling to keep the battery charged later, and you’ve got a working UPS setup to keep the comms online.

Combined with a UPS to run the rest of your computers and networking equipment, this is a great solution to stay online during local power outages. We’ve featured some other great UPS hacks over the years, too, like these supercap UPSs for special cases. If you’ve got your own nifty power hacks, don’t hesitate to drop us a line!

Share Your Projects: Leave Breadcrumbs

August 9, 2023 by Arya Voronova 20 Comments

I’ve talked about a low-effort way to document your projects by taking plenty of pictures, and about ways that your PCBs could be documenting themselves. Today, let’s talk about a quick and easy way that you could help other hackers as you go through your own hacking adventures — leaving breadcrumbs.

In short, breadcrumbs are little pieces of crucial information that you had to spend time to figure out. They are solutions to problems that another hacker just like you could stumble upon in the future, something that you perhaps wish you didn’t have to figure out on your own, and certainly something that others won’t need to spend time figuring out.

Breadcrumbs are about saving time, for you and others. It helps if you think of your solved problems in terms of time spent. If you figure out a small problem and then publish your solution, you might be saving half an hour, a full hour, or a good few hours of time another hacker that’s could even be less experienced in debugging than you. In fact, your breadcrumb might even make a difference between someone completing a project and abandoning it!

However, there’s also the trade-off of taking time to document something. If you can’t publish your solution in a few minutes’ time, it might become much harder to persuade your brain to publish the next time you have something notable. Here’s a guideline: if you’ve just figured out a cool terminal command that helps you solve a certain kind of problem, you should have a quick way to publish that command within a minute. The good news is, the internet has a hundred different places you could easily share your findings, depending on the kind of problem you’ve solved!

2600 Breaks Free From DRM With PDF/EPUB Subscription

July 21, 2023 by Tom Nardi 13 Comments

Hackaday has been online in some form or another since 2004, which for the Internet, makes us pretty damn old. But while that makes us one of the oldest surviving web resources for hacker types, we’ve got nothing on 2600 — they’ve been publishing their quarterly zine since 1984.

While the physical magazine can still be found on store shelves, the iconic publication expanded into digital distribution some time ago, thanks largely to the Kindle’s Newsstand service. Unfortunately, that meant Amazon’s recent decision to shutter Newsstand threatened to deprive 2600 of a sizable chunk of their income. So what would any group of hackers do? They took matters into their own hands and spun-up their own digital distribution system.

As of today you’re able to subscribe to the digital version of 2600 in DRM-free PDF or EPUB formats, directly from the magazine’s official website. Which one you pick largely depends on how you want to read it: those looking for the highest fidelity experience should go with PDF, as it features an identical layout to the physical magazine, while those who are more concerned with how the content looks on their reader of choice would perhaps be better served by the flexibility of EPUB. After signing up you can download the current Summer issue immediately, with future issues hitting your inbox automatically. Load it onto your home-built Open Book, and you can really stick it to the establishment.

While the ending of this story seems to be a happy one, we can’t help but see it as a cautionary tale. How many other magazines would have the means and experience to offer up their own digital subscriptions? Or for that matter, how many could boast readers savvy enough to utilize it? The reality is many publications will be injured by Amazon’s decision, some mortally so. That’s a lot of power to be put into the hands of just one company, no matter how quick the shipping is.

Your Guide To Using Amazon’s Sidewalk Network For The Internet Of Things

May 1, 2023 by Lewin Day 61 Comments

As the Internet of Things became a mainstream reality, it raised an interesting point about connectivity. We quickly learned it wasn’t ideal to have every light bulb, toaster, and kettle buzzing away on our main WiFi networks. Nor was it practical to sign up for a cellular data plan for every tracker tag or remote sensor we wanted to use.

To solve this issue, various tech companies have developed their own low-power mesh networking solutions. Amazon’s Sidewalk network is one of the widest spread in the US. Now, it’s opening it up for wider use beyond its own products, and you can get in on the action.
