I’m trying out Regard3d, an open-source photogrammetry tool. A couple of items, memo-to-self style of thing:

    • its database does not have cellphone cameras in it. Had to google around to find the details on my particular phone
    • its database is this: 
    • just had to find where it was on my machine, and then make an entry for my phone. I’m still not sure whether I got the correct ‘width’ dimension – running with this. 
    • nb don’t do this with excel – excel does weird things to csv files, including hidden characters and so on which will cause Regard to not recognize your new database entry. Use Sublime Text or another text editor to make any changes. You can double click on an image in the imageset list inside Regard and add the relevant info one pic at a time, but this didn’t work for me.
    • I took the images with Scann3d, which made a great model out of them. But its pricing model doesn’t let me get the model out. So, found the folder on the phone with the images, uploaded to google drive, then downloaded. (Another nice thing about Scann3d is when you’re taking pictures, it has an on-screen red-dot/green-dot thingy that lets you know when you’re getting good overlap.)
    • Once I had the images on my machine, I needed to add exif metadata re focal length.  Downloaded, installed, exiftool. Command:  exiftool -FocalLength="3.97" *.jpg
    • In Regard3d, loaded the picture set in.
    • The next stages were a bit finicky (tutorial) – just clicking the obvious button would give an error, but if I had one of the image files selected in the dialogue box, all would work.
    • here’s a shot of the process in…erm… process…

  • Console would shout ‘error! error!’ from time to time, yet all continued to work…

I’m pretty sure I saw an ‘export to meshlab’ button go by at some point… but at any rate, at the end of the process I have a model in .ply and .obj!  (ah, found it: it’s one of the options when you’re ready to create the surface). All in all, a nice piece of software.



Markov Music; or; the Botnik Autogenerator Reel

Markov Music; or; the Botnik Autogenerator Reel

You must’ve seen the Harry Potter chapter written with markov chains / predictive text (not AI, I should point out). I went to the site, and thought, I wonder what this could do with music written in the text ABC notation format. So, grabbing the same source files that gave us Mancis the Poet (where I used RNN to generate the complete files), I loaded Botnik with Cape Breton Fiddle tunes. Then I generated a text, clicking madly in the middle of the interface. The result:

A ab|ca fe|dfba f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a|
Da|bf{g}fe b a2 f2|d a ab|ca fe|dfba f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a|

Which, when you add some made-up metadata like so to the front:

T:Botnik Autogenerator Reel
O:21st century Canadian

…becomes a file that can be turned into MIDI, thence mp3. You can generate your own fiddle line with this corpus:

And here you go: the music notated above as MIDI piano:

The Human in the Digital Humanities

The Human in the Digital Humanities

I’m giving a talk in a month’s time, for the launch of a new DH centre at Drew University. This necessarily involves travel to the US. I’ve decided to go because these kinds of events are more important, in my view, than (say) traveling to a conference. Starting something that will benefit students > giving a paper that merely adds a line to my cv. The way things are going state-side, I see reasons for hope, and reasons for despair, and so if I can help further DH down there, I guess I’d better go. Because I do see DH as something that, when it turns outward, as something that can (does?) make a difference.

Or at least, it should.

Anyway, the title is ‘The Human in the Digital Humanities’. As I sketch it out, I wonder if I shouldn’t call it ‘the Humane’, which is a slightly different kettle of fish.  As part of my writing process, I also asked folks what they thought such a talk might cover; the point of this post is to gather the results together, to date. I also wanted to draw attention to this tweet by Paige Morgan, as I think it (and its thread, and resulting conversations) captures some of the things I want to talk about.

So, here are the other tweets. My initial tweet:

Let’s Imagine

Let’s Imagine

There’s a game I play, sometimes, when I wander around campus. You’ve probably played it too. My version of ‘let’s imagine’ always seems to end up focussed on the physical fabric of the university. How I’d make it look. What buildings I’d build. Articulations with the larger city. So let’s imagine.

Carleton has an enormous hole in its campus, overlooking one of the prettiest locations in the city, Dow’s Lake. Here’s the map:

See all that empty grey area above the words ‘Carleton University’? Gravelled parking lot, snow dump in the winter. And that’s it. Here’s an aerial photo:

I’d love to fill that with a ginormous building that fronts onto Dow’s Lake. This building would be a kind of studio space for every national, regional, and local museum in the Ottawa area. Every single one of these institutions can show but a fraction of their collection. So, I’d love to build a space where materials can be rotated in, so that they are available for research, teaching, and the public. A giant living lab for our national collections. Since the collections span every department and faculty we have, I see no reason why this couldn’t break down silos and barriers across disciplines, in our teaching. I’d have a big ol’ international design competition, make the thing a jewel, too.

Apparently, our campus master plan  imagines this as a ‘North Campus’, filled with lots of different buildings. Sounds good. Can we make one of them be the Carleton Musea?

…while I’m at it, I’d like a pony, too.

Procedural History

Procedural History

I see this is my third post with this title. Ah well. Just playing with a script I found here

shawngraham$ python2
In the beginning there was “Baubrugrend Free State”, “Dominion of Clioriwen”
In that era, the people could bear it no longer, and so these ones rebelled from ‘Baubrugrend Free State’ ==> ‘Province of Vrevrela’
In that era, the people could bear it no longer, and so these ones rebelled from ‘Province of Vrevrela’ ==> ‘Free People’s Republic of Craepai’
It is a terrible thing when brothers fight. Thus ‘Free People’s Republic of Craepai’ became “Eiwerela”, “Broteuvallia”
It is a terrible thing when brothers fight. Thus ‘Dominion of Clioriwen’ became “Duchy of Corica”, “Orican Republic”
The thirst for new lands, new glory, and the desire to distract the people, led to new conquests ‘Duchy of Corica’ conquered ‘Eiwerela’
The thirst for new lands, new glory, and the desire to distract the people, led to new conquests ‘Duchy of Corica’ conquered ‘Broteuvallia’
The thirst for new lands, new glory, and the desire to distract the people, led to new conquests ‘Duchy of Corica’ conquered ‘Orican Republic’
In that era, the people could bear it no longer, and so these ones rebelled from ‘Duchy of Corica’ ==> ‘United States of Heukan’
In that era, the people could bear it no longer, and so these ones rebelled from ‘United States of Heukan’ ==> ‘Kingdom of Amoth’
END “Kingdom of Amoth”

The script can also make a nice diagram; now to get it to write the history AND the diagram at the same time.

The directionality of the arrows is a bit confusing. You almost have to read it backwards. However, since it is just a .dot file, I think I can probably load it into something like yEd and make a prettier timeline.

update I’ve added Tracery to the script, made the output a bit more lyrical:

> shawngraham$ python2

Gather by, young ones, and let me tell you of our nations and peoples.

In the beginning there was “Duchy of Corica”

These people shared a single peninsula, shielded from the rest of the world by tall mountains.

Flooding ruined the crops; the famine weakened them all and so, ‘Duchy of Corica’ dissolved in fragments, eventually becoming “Province of Eabloris” and “Voches” and “Uamafai “

A few years later, the strength of the people could bear it no longer, and they rose up in violent revolution. The old ‘Province of Eabloris’ was no more; a new dawn broke on ‘Heawoth’.

As it came to pass, the Queen gave up power and fled into exile. The old ‘Heawoth’ was no more; a new dawn broke on ‘Iroa’

Flooding ruined the crops; the famine weakened them all and so,“Uamafai ” and “Voches” became ‘Eiwerela’.

As it came to pass, the Satrap gave up power and fled into exile. The old ‘Eiwerela’ was no more; a new dawn broke on ‘Oyune’

Low cunning and high treachery divided them and so, ‘Oyune’ dissolved in fragments, eventually becoming “Broteuvallia” and “Islands of Hekla” and “Kingdom of Abroth”.

Low cunning and high treachery divided them and so, ‘Islands of Hekla’ dissolved in fragments, eventually becoming “Satrapy of Yaislaxuin” and “Dominion of Clioriwen”.

The clouds grew dark, and hunger stalked the land, so sickness weakened them all and so, “Dominion of Clioriwen” and “Satrapy of Yaislaxuin” became ‘Kingdom of Amoth’.

The thirst for new lands, new glory, and the desire to distract the people, led to new conquests. ‘Broteuvallia’ conquered ‘Kingdom of Amoth’

A few years later, the Queen gave up power and fled into exile. The old ‘Iroa’ was no more; a new dawn broke on ‘Province of Vrevrela’

Standing proud upon the ruins there are only now “Broteuvallia”and “Kingdom of Abroth”and “Province of Vrevrela”.

Procedural History

Procedural History

Procjam 2017 – ‘make something that makes something!’ is on right now.  My interest in procedural generation at the moment concerns the way we think about something when we’re making something else that makes that something. (Still with me?)

I’ve dabbled in sound, and in text, and in bots; now I’m thinking about procedural history. Now, in a way, that was what I was doing when I got into this whole DH scene way back when – agent based modeling. But there’s something about the way something like Dwarf Fortress writes history – and people in turn flesh those histories out (this was the subject of an undergraduate honours thesis done for me by a student, who, to my frustration, has never posted the work online).

So I’m coming back to it. This is also partly because I’m interested in how ideas about how cities work are codified in city sim games that then get draped in the trappings of Antiquity (am writing a piece on this at the moment). Today I came across a very cool project from the procjam community, by David Masad (who I note is using ABM for his dissertation work), called ‘WorldBuilding‘. It takes the algorithm for fantasy maps that you may have seen at play in that twitter account, ‘uncharted atlas’, generates a world by simulating landscape and erosion, introduces an ABM of nomads who settle down into cities, who interacted via trade routes, and who pay tribute or go to war with one another.

All within one python notebook.

Here is the dusty plateau, fringed by a verdent coast, where one or two valleys give access to the interior. Nomads arrive, and in the course of time, settlements and routes emerge:

And we can begin to model their interactions.  Masad is using Axelrod’s Tribute Model. He then dips into the logs and is able to generate the annals of this world:

“From 0 to 49, Ceotpe saw slow growth. In this period it received tributes from Oqlou.
From 49 to 50, Ceotpe saw slow decline. In 50 it, and joined its allies in one battle.
From 50 to 87, Ceotpe saw slow growth. In this period it received tributes from Oqlou.
From 87 to 88, Ceotpe saw slow decline. In 88 it, and joined its allies in one battle.
From 88 to 90, Ceotpe saw slow decline. In this period it, and joined its allies in one battle.
From 90 to 92, Ceotpe saw rapid decline. In this period it fought a war against Oqlou.
From 92 to 99, Ceotpe saw slow growth.”

The code also produces a line chart of a city’s fortunes – for instance, the city of Tigei had a much different history:

The logs spell out what was happening:

” 43, ‘Receive tribute’, ‘Oqlou’
50, ‘Joined war against’, ‘Itykca’
62, ‘Receive tribute’, ‘Oqlou’
73, ‘Receive tribute’, ‘Oqlou’
88, ‘Joined war against’, ‘Itzyos’
90, ‘Joined war against’, ‘Itzyos’
92, ‘Led war against’, ‘Oqlou'”

I could imagine, say in a senior undergrad seminar where I had the time and commitment from students, to use this code as the kernal for a deep exploration of how history intersects with games and simulation. How do you get from an annal to a history? The students would work at the creative tension between what a game shows and what a game merely suggests and what the player brings to that gap.

Something like that. It’s dark, it’s november, the time changed, I’m tired, not exactly coherent. But there’s something extremely cool here (not least the usage of jupyter notebook to illuminate the code). My gut, which I consult on such things, thinks this stuff is important.

Old Bones Daily – HeritageJam 2017 Entry

Old Bones Daily – HeritageJam 2017 Entry

Update: We won!

I’m pleased to take part in the 2017 HeritageJam; Kate and I present Old Bones Daily:

  • Visit online at
  • Make your browser full-screen for best effect
  • Fully responsive so can be read equally well on mobile
  • Reload the page for the latest headlines and stories and photos


The paradata for the project is printed as the fifth column on the newspaper’s front page.

This ‘newspaper’ that you are looking at pays hommage to that older newspaper culture of reprinting, while at the same time commenting, on modern ‘news media’ by procedurally generating texts from the ‘bones’ of generative grammar. Each time this page is reloaded, the news is generated anew from a Tracery grammar. This grammar is derived from the study of 19th century newspapers in Western Quebec (The Equity) and northern New York State. It selects passages from these papers where the word ‘bone’ is present or implied, and recombines them in sometimes surprising or revealing ways. There are stories of injury, and columns with helpful advice. Sometimes a humorous anecdote is recounted; sometimes popular accounts of the latest academic research.

And sometimes, out and out fraud.

Some of the passages are presented verbatim, using the language and reflecting the mores of the age (with no generative grammar intervention) thus demonstrating another perspective on ‘bones’ and whose are accorded human dignity. The passages were collected in the first place by ingesting OCR’d papers into AntConc, and generating a concordance and keywords-in-context file.

Tracery was designed and built by Kate Compton @galaxykate. This newspaper layout was designed and shared by user silkine on Images are drawn from the British Library’s Flickr stream, where they have been tagged with the word ‘bone’ – thus, another algorithmic expression of the bones underlying the web.

To replicate this newspaper for your own amusement, consult the file, newsgrammar.js and insert new values in the keys. To alter the layout and placement of these elements on the newspaper, create new var and associated div in the js\app.js file. Place the div in the appropriate location in the main index.html file. Extra css or html for a particular chunk of text should be wrapped inside the values in the newsgrammar.js file. For a tutorial on how Tracery functions, see Shawn Graham’s tutorial at The Programming Historian. Tracery can power webpages, games, and twitterbots. What would be the effect of ‘Old Bones Daily’ if it were translated into the new news medium of Twitter?

A Twitter Hiatus

A Twitter Hiatus

For some time now, Twitter just hasn’t been fun. Don’t get me wrong: if you want to know what’s going on in digital archaeology (or whatever field) and you want to know what your peers are up to, it’s hard to beat.

But it’s been making me sick. It’s been making me anxious. It’s been eating far too much of my time. The world’s shitty enough as it is, without giving the shittiness a direct pipeline into my brain.

There’s no need to iterate all the bad ways Twitter serves to make the world a worse place, including its use of addictive design principles. It’s baked in, as they say: the trolls, the nazis, and Trump will never be booted off, because they generate clicks, they generate attention. Women and people of colour on the other hand…

So I’m taking a break. I’m trying. I’ve installed a site blocker on all my devices. In recognition that I’ve been such a heavy twitter user for so long, and that’s the principle vector for how some people collaborate with me, I have things set up so that I can check my DMs periodically. I did retweet some things related to singer-poet Gord Downie’s death, which as a Canadian of a certain age, well, you just have to do.

Other than that, I’ve been off Twitter for a week now. And dammit if I don’t feel more productive already…

If you need me, email me.

Call for Collaborators: The Open Digital Archaeology Textbook Environment (ODATE)

Call for Collaborators: The Open Digital Archaeology Textbook Environment (ODATE)

The Open Digital Archaeology Textbook Environment is a collaborative writing project led by myself, Neha Gupta, Michael Carter, and Beth Compton. (See earlier posts on this project here).  We recognize that this is a pretty big topic to tackle. We would like to invite friends and allies to become co-authors with us. Contact us by Jan 31st; see below.

Here is the current live draft of the textbook. It is, like all live-written openly accessible texts, a thing in the process of becoming, replete with warts, errors, clunky phrasing, and odd memos-to-self. I’m always quietly terrified to share work in progress, but I firmly believe in both the pedagogical and collegial value of such endeavours. While our progress has been a bit slower than one might’ve liked, here is where we currently stand:

  1. We’ve got the framework set up to allow open review and collaboration via the web annotation framework and the use of Github and gh-pages to serve up the book
  2. The book is written in the bookdown framework with R Markdown and so can have actionable code within it, should the need arise
  3. This also has the happy effect of making collaboration open and transparent (although not necessarily easy)
  4. The DHBox computational environment has been set up and is running on Carleton’s servers. It’s currently behind a firewall, but that’ll be changing at some point during this term (you can road-test things on DHBox)
  5. We are customizing it to add QGIS and VSFM and some other bits and bobs that’d be useful for archaeologists. Suggestions welcome
  6. We ran a test of the DHBox this past summer with 60 students. My gut feeling is that not only did this make teaching easier and keep all the students on the same page, but the students also came away with a better ability to roll with whatever their own computers threw at them.
  7. Of six projected chapters, chapter one is in pretty good – though rough – shape

So, while the majority of this book is being written by Graham, Gupta, Carter and Compton, we know that we are leaving a great deal of material un-discussed. We would be delighted to consider additions to ODATE, if you have particular expertise that you would like to share. As you can see, many sections in this work have yet to be written, and so we would be happy to consider contributions aimed there as well. Keep in mind that we are writing for an introductory audience (who may or may not have foundational digital literacy skills) and that we are writing for a linux-based environment. Whether you are an academic, a professional archaeologist, a graduate student, or a friend of archaeology more generally, we’d be delighted to hear from you.

Please write to Shawn at shawn dot graham at carleton dot ca to discuss your idea and how it might fit into the overall arc of ODATE by January 31st 2018. The primary authors will discuss whether or not to invite a full draft. A full draft will need to be submitted by March 15th 2018. We will then offer feedback. The piece will go up on this draft site by the end of the month, whereupon it will enjoy the same open review as the other parts. Accepted contributors will be listed as full authors, eg ‘Graham, Gupta, Carter, Compton, YOUR NAME, 2018 The Open Digital Archaeology Textbook Environment, eCampusOntario…..
