Home - Memory of Mankind

A time capsule for the long now. Laser-etched ceramic tablets in an Austrian salt mine carry memories of our civilisation in three categories: news editorials, scientific works, and personal stories.

You can contribute a personal story, your favorite poem, or newspaper articles which describe our problems, visions or our daily life.

Tokens that mark the location of the site are also being distributed across the planet.

Why the Future of Data Storage is (Still) Magnetic Tape - IEEE Spectrum

It turns out that a whole lot of The So-Called Cloud is relying on magnetic tape for its backups.

Offline-Friendly Forms by Max Böck

A clever use of localStorage to stop data from being lost when your visitors are offline.

Putting Civilization in a Box Means Choosing Our Legacy

A run-down of digital preservation technologies for very, very long-term storage …in space.

Brendan Dawes - Back your sh*t up!

My back-up strategy is similar to Brendan’s (using Super Duper and Backblaze):

In backup parlance there’s a thing called 3-2-1. That is, you should three copies of your files — two locally on different devices and one off site.

But I only do my local back-ups once a week (eek!)—I should do better.

The Internet Isn’t Forever

A terrific piece by Maria Bustillos on digital preservation and the power of archives, backed up with frightening real-world examples.

Because history is a fight we’re having every day. We’re battling to make the truth first by living it, and then by recording and sharing it, and finally, crucially, by preserving it. Without an archive, there is no history.

Workers at Your Service | WebKit

Here’s an interesting insight on how WebKit is going to handle the cleanup of unused service workers and caches:

Service worker and Cache API stored information will grow as a user is browsing content. To keep only the stored information that is useful to the user, WebKit will remove unused service worker registrations after a period of a few weeks. Caches that do not get opened after a few weeks will also be removed.

Arch Mission

Off-site backups of humanity’s knowledge and culture, stored in different media (including pyramidal crystals) placed in near-Earth orbit, the moon, and Mars.

We are developing specialized next-generation devices that we call Archs™ (pronounced “Arks”), which are designed to hold and transmit large amounts of data over long periods of time in extreme environments, including outer space and on the surfaces of other planetary bodies.

Our goal is to collect and curate important data sets and to install them on Archs™ that will be delivered to as many locations as possible for safekeeping.

To increase the chances that Archs™ will be found in the future, we aim for durability and massive redundancy across a broad diversity of locations and materials – a strategy that nature itself has successfully employed.

eBay’s Font Loading Strategy | eBay Tech Blog

Here’s the flow that eBay use for the font-loading. They’ve decided that on the very first page view, seeing a system font is an acceptable trade-off. I think that makes sense for their situation.

Interestingly, they set a flag for subsequent visits using localStorage rather than a cookie. I wonder why that is? For me, the ability to read cookies on the server as well as the client make them quite handy for situations like this.

How much storage space is my Progressive Web App using? | Dean Hume

You can use navigator.storage.estimate() to get a (vague) idea of how much space is available on a device for your service worker caches.

The Lost Picture Show: Hollywood Archivists Can’t Outpace Obsolescence - IEEE Spectrum

There are three parts to digital preservation: format, medium, and licensing. Film and television archives are struggling with all three.

Format:

Codecs—the software used to compress and decompress digital video files—keep changing, as do the hardware and software for playback.

Medium:

As each new generation of LTO comes to market, an older generation of LTO becomes obsolete. LTO manufacturers guarantee at most two generations of backward compatibility. What that means for film archivists with perhaps tens of thousands of LTO tapes on hand is that every few years they must invest millions of dollars in the latest format of tapes and drives and then migrate all the data on their older tapes—or risk losing access to the information altogether.

Licensing:

Studios didn’t see any revenue potential in their past work. They made money by selling movie tickets; absent the kind of follow-on markets that exist today, long-term archiving didn’t make sense economically.

It adds up to a potential cultural disaster:

If technology companies don’t come through with a long-term solution, it’s possible that humanity could lose a generation’s worth of filmmaking, or more.

The People’s Cloud

A documentary by Matt Parker (brother of Andy) that follows in the footsteps of people like Andrew Blum, James Bridle, and Ingrid Burrington, going in search of the physical locations of the internet, and talking to the people who maintain it. Steven Pemberton makes an appearance in the first and last of five episodes:

  1. What is the Cloud vs What Existed Before?
  2. Working out the Internet: it’s a volume game
  3. The Submarine Cable Network
  4. How Much Data Is There?
  5. Convergence

The music makes it feel quite sinister.

Memory of Mankind: All of Human Knowledge Buried in a Salt Mine - The Atlantic

Like cuneiform crossed with the Long Now Foundation’s Rosetta Project.

He will laser-print a microscopic font onto 1-mm-thick ceramic sheets, encased in wafer-thin layers of glass. One 20 cm piece of this microfilm can store 5 million characters; whole libraries of information—readable with a 10x-magnifying lens—could be slotted next to each other and hardly take up any space.

Is DNA the Future of Data Storage? - WSJ

It’s still many years away from being a viable storage option, but here’s the latest on using DNA to back up our collective data.

Magnetic tape may survive a few decades, and DVDs even longer, but they are by no means immortal. Data stored in DNA, provided it’s kept cold and dry, could last for thousands of years.

A cautionary tale of digital preservation.

.generation is a short film that intimately documents three millennials in the year 2054 - uncovering their relationships with technology in the aftermath of the information age.

Persistent Storage | Web Updates - Google Developers

Here’s an interesting proposal from Google for a user-initiated way of declaring a site’s offline assets should be prioritised (and not wiped out in a clean-up). Also interesting: the way that this idea is being tried out is through a token that you can request …sure beats prefixes!

Eternal 5D data storage could record the history of humankind

360 terabytes of data stored for over 13 billion years:

Coined as the ‘Superman memory crystal’, as the glass memory has been compared to the “memory crystals” used in the Superman films, the data is recorded via self-assembled nanostructures created in fused quartz. The information encoding is realised in five dimensions: the size and orientation in addition to the three dimensional position of these nanostructures.
