Search Challenge (9/2/15): How to search in a scanned document?

If your research is like mine... 

... you fairly frequently find a document that's from another era.  It doesn't even have to be that long ago before you find yourself dealing with infernally annoying crufty docs.  

For instance, when I'm searching, I fairly often find a document that was scanned as an image. It's great to have the document in the first place, but as a scan, it's often less than completely useful.  

Here's an example.  A document I found in one of my research studies was this excellent paper that's available only in a scanned PDF format.  (Here's the LINK to the paper.)  When you open it up, you'll see sections that appear like this:  

Of course, our usual Control-F / CMD-F tricks don't work on this kind of scanned doc, and since this is a long paper, it makes it very much harder to read.  In particular, what I WANT is this--something I CAN use Control-F on:  

Our SearchResearch Challenge for this week is meant to give you an additional powerful tool for importing scanned documents and making them findable.  

1.  How can you transform this document (LINK) into something that you can search within? 
2.  Once you've done that, can you determine how many times the authors refer to "multiple documents" in that paper?  (This was my original search task--finding interesting papers about how people read multiple documents at the same reading session. That's how I found this paper.)  

So this Challenge is really about "tool finding" -- can you figure out how to convert from a scanned document into a readable / findable / searchable one?  

(Big hint: It's much easier than you think.)  

Let us know how you found out how to do the magic process!  

Search on!

Answer: Know how to create a timeline?

There are many solutions... 

... and it's taken me a LOT longer than I thought it would to explore them.  (Hence, this post being a day-late.)  

The thing is, it's not hard to find timeline creation tools, but it IS tricky to find one that has the right set of features.  Details below... 

Our Challenge from last week was: 

1.  Can you find an online tool (or app) that will let you take a collection of events (both points in time, and periods of time) and create a timeline?   
2.  Using that tool, can you find a data set that you'd like to see as a timeline? (I've got a link to a sample data set below.)  

There's the obvious Challenge here (find a timeline tool you can use), but also a deeper SRS question:  How do you find tools?  

Here's what I did... 

My first query was for:  

     [ timeline ] 

Lots of queries would have worked here, but my plan is to find out what KINDS of timelines are available, and then work backwards to see how they were created.  So I looked in Google Images to see what kinds of timelines were possible.  

Notice the top row?  "Blank" "Simple" "Kids" "Clipart" and "Examples"?   Those are different clusters (that is, related types) of timelines.  There are blank timelines there, but what we really need is a tool to make a timeline, not just a template.

My next query was to see if there were particularly nice "visualizations" of timelines.  That word, visualization, is one of those "terms of art" that describes visual diagrams generally.  I did this query because I wanted to find a tool or system that would help me create timelines.

These were good, and by opening up a few of them, I found a number of tools.  But some were too simple, some too complicated, and more than a few were apps for use on a mobile device.  

So I went back to regular Google and did this search: 

     [ timeline tool ] 

THAT was successful and led me to a bunch of tools.  My plan was to illustrate several of them to show which worked in particular ways.  But it turns out that finding just the right feature set is tricky. 

So let me show you my first timeline solution, which turned out to be both very nice, elegant, and simple to use.  

After my search, the first hit was TimelineJS from Knight Lab  So I used it to create the timeline below.  (But keep reading for the rest of the story below.)  

This is a really nicely made tool that just requires that you create a spreadsheet, import it into their tool, and it will give you back a nicely interactive timeline.  

I used the spreadsheet of data about the Viet Nam war that I gave in the last post.  Following their instructions, I copy-pasted the data from my spreadsheet into theirs, edited a couple of cells to fix up the dates into the style they wanted, and created a Google Spreadsheet in their format, which then gives us this timeline: 

An image of the KnightLab timeline.  (I include it here in case the interactive version stops working.) 

Which is just a screengrab of the interactive version embedded here.  Click around a bit to explore the entire data set.  Note that you can press-and-hold to drag the timeline left/right, or use the + and - buttons to zoom in and out.  (Kudos to these folks, this is a very nice tool.)  

But I didn't end my search there.  

As I mentioned, it's fairly easy to find timeline tools, but here's what happened: I tried using each of these tools to make a timeline as described.  BUT the devil is in the details.  

Tiki-Toki - a beautiful tool, but there's no way to import events into the timeline, you have to make them There's no way I'm going to do that for the entire Viet Nam war timeline!  So I gave up.   Same comment for several other timeline tools (e.g., Capzles and ReadWriteThink's Timeline).  No import capability?  Really?  

Dipity - I couldn't figure out how to make a timeline.  (The UI is kinda crazy; I spent 30 mins trying to make a timeline, and gave up.) 

TimeGlider - requires that you be a student or pay for the account. (I have nothing against paid services, but most SRS readers don't make that many timelines, so I'm going to skip over ones that require payment.)  

I also tried some more complex ones.  Brian Croxall's Timeline tool looks really promising.  But after futzing around with connecting JSON export features from Google Spreadsheets (and failing), I determined that the documentation is out of date--or at least I couldn't figure out how to make it work.  (And I got SO close! But just couldn't make the data connector work.)  

And of course, there's a nice Excel spreadsheet tool to create timelines... sort of.  Vertext42 has a tutorial on how to use Excel to create a timeline by modifying their box-plot diagram tool.  And you'd think this would be perfect... but it turns out that you have to make all of the event labels one-by-one.  You can't just do a bulk import of the labels from a spreadsheet!  (Isn't that odd?  Yes, but the reason is that the timeline works by adding labels, one-by-one, to the chart.  And that can't be driven by a table...  Sigh.)  

And of course, there's the Google Charting interface for timelines, which requires adding your data into the Javascript code.  I know how to do that, and I can do it by writing a program... but that's a little over the top for this blogpost. (I might well write about it another day... it's actually fairly interesting.  I'll see if I can't figure out a nice, straightforward way to write that one up.)  

If you want to write code, you can always use a visualization toolkit like VisJS or D3 both of which can create extremely nice timelines, but require a bit of coding.  

Search Lessons 

Of course the big lessons I took away from this was: 

A.  The devil for using a tool is in the details.  In particular, while a simple search for [ topic tool ] or [ topic app ] is enough to find you a plethora of tools, determining which one of these is actually right for your use--well, that's a bit trickier.  You still have to spend time testing each of them out. 

And perhaps the biggest tip I have for searchers doing tool evaluations is this:

B.  Always test a tool from start to finish with a minimum data set.  A common mistake is to invest a lot of time testing out a tool (for example, adding 100 of the War's events by hand), and then figuring out in the very-last-step that the output has no embeddable widget (or whatever the problem is).  DO NOT spend more time adding in tons of data until you know it will work from beginning to end.  

Thanks to everyone who put something into the shared document.  Those are great!  Thanks!  

As always, keep searching on!

Search Challenge (8/26/15): Know how to create a timeline?

There are many great info visualization tools... 

... but the plain old timeline is still incredibly useful for organizing a collection of events that happen over time.  

For instance, here's a timeline showing the history of Macs (you can click on it to see in full-resolution). 

Macintosh History in one timeline.

Or you can start to see patterns in the sequence of events, as in this chart from the CDC about the course of events in patients with Ebola.  

Sequence of events in 3 patients with Ebola entering the US.  Source: CDC

There are many different kinds of timelines, each style with its own advantages.  Every so often it would be great to be able to make a timeline of your own from a set of events that you care about.  

I needed to do this the other day to make a sequence of events clear.  "Aha!" I thought, "I'll just make one in my handy-dandy illustration app." 

But as I started drawing, I realized that one of the adages of SearchResearch is: 

 When you're doing something repetitive, look for a tool to do it for you... 

So I stopped drawing lines and putting times into the sketch, and opened up my search engine.  Guess what?  I found several timeline generation tools out there.  I just converted my data into an acceptable format (which took almost no time at all) and voila!  I had a timeline very shortly thereafter.  Even better--it was an interactive timeline--you could scroll back and forth or zoom in and out.    

This brings me to today's Challenge: it's only nominally a Search Challenge (although there's some of that here), but it's a sensemaking tool Challenge.  

1.  Can you find an online tool (or app) that will let you take a collection of events (both points in time, and periods of time) and create a timeline?  
2.  Using that tool, can you find a data set that you'd like to see as a timeline? (I've got a link to a sample data set below.)  

The idea here is that as SearchResearchers, we sometimes need to step back and realize that using a tool to help organize information is a really great thing to do.  Databases are one kind of organizing tool  (we'll cover a problem like that in a future SRS Challenge), but other kinds of info visualizations can be just as useful.

Ideally, I'd love to see everyone's timeline.  So, please post a link to your timeline in the comments to the blog.  Or, if you're feeling ambitious, please post it in our shared doc: 

      SearchResearch TimeLines (link to doc)

Of course, it would be great if you searched for your own data set, but if you'd like to get started and don't want that hassle, here's a Google Spreadsheet for you with Events from the Viet Nam war.   Note that some of the events are time periods (a month, or a year), while others are exact days.  

Search on!  

(And make those timelines!)

Answer: Why all the crazy capital letters?

One of the stranger things you've seen..

but perhaps hadn't thought about... is the strange way in which older texts are capitalized.  Noticing this led me to our most recent Search Challenge which asks why the capitals seem scattered almost at random:  

Printed copy of the Declaration by John Dunlap, 1776. Source: Library of Congress.

1.  What's the story with the Capital letters in the 18th century?  Were they just throwing in caps at random, or is there a Rhyme, and Reason to their capitalization?  
I started researching this one by looking at the original version of the Declaration and a few other, different but contemporary copies.  Here's one: a 1823 William Stone facsimile of the original Declaration.  Stone may well have used a wet pressing process (that is, he pressed a contact sheet onto the original, removing traces of ink from the original document for the purpose of making the engraving).  

I started here because I wanted to see how consistent their capitalization practices were.  As you see, I've marked in pink all of the caps that seem arbitrary to me--the C in "Course," the L in "Laws" and so on.  But notice the p in "people" of line #1? (The yellow rectangle above.)   That's capitalized in preceding printed version (from 1776).  If you compare the original written version with printed versions, it's clear that the capitalization pattern isn't very consistent.  

Here are a few pages of books from the past few hundred years:  notice how the pattern of capitals change... The first book here from 1539 doesn't have many capitals at all--a few, but rarely.  While later texts add more and more... 

1539 Johannes Velcurio
Commentarii in Universum

1676 book by Heinrich Cornelius Agrippa von Nettesheim
The Vanity of Arts and Sciences.

1774 Bible from St. Andrews special collections.

1770 book by John Dove, Strictures on Agriculture.

1774 book by Arthur Young on "A Course of Experimental Agriculture"
I got these all from Google Books as a way to get to some original content.  I just did a search for [Agriculture] since I knew that this was a topic that has been written about for hundreds of years, then I time-restricted the books to particular centuries.  

To open the date-restriction in Google Books, you need to click on "Search Tools" and then fill in your dates: 

Doing that repeatedly gave me all of the samples from above.  By comparing different editions of the same book (or the Declaration), I found that capitalization practices varied quite a bit over time, and even across editions. (For that fact, spelling varied as well. On the tenth line from the bottom. Jefferson spelt British with two 'T's. It's rendered in the more current spelling elsewhere. 'Neighbourhood' is written in the English form with what we consider an extra "u." Later versions of the Declaration have standardized the spelling and (to an extent) the capitals.  

But to learn more, I first did a search for: 

     [  capitalization Declaration of Independence ] 

and found a nice article on the site about caps in the Declaration. In there, they point out that "The non-standard capitalization of key words, on the other hand, functions to heighten emphasis and dramatic effect. Examples of the liberal use of capitalization in the Declaration of Independence include: “Laws of Nature” “Form of Government” “Safety and Happiness” “Standing Armies” “Free and Independent States”  

In other words, there aren't strict guidelines, but the capitalization was more a typographic means of expressing emphasis.  

My next search: 

     [ history of capitalization ] 

leads to a wealth of resources, one of which was the Wikipedia page on Letter Case, which told me that "Other languages vary in their use of capitals. For example, in German all nouns are capitalised (this was previously common in English as well), while in Romance and most other European languages the names of the days of the week, the names of the months, and adjectives of nationality, religion and so on normally begin with a lower-case letter."  

This now starts to move into our next question... 

2.  Related: How / why / when did our practice of capitalization change to what it is currently?  (And, for extra credit, do other countries follow the same pattern of capitalization that we English-speaking types do?  For that fact, is the practice of capitalization the same in the US as in the UK?)  
Traditionally, certain letters were rendered differently according to a set of rules. In particular, those letters that began sentences or nouns were made larger and often written in a distinct script. There was no fixed capitalisation system until the early 18th century. The English language eventually dropped the rule for nouns, while German kept it.

Continuing down the list of hits from my last query, I found a fascinating thread in the English language section of StackExchange.  (If you don't know StackExchange, it's well worth visiting.  The forums tend to be very high quality, with lots of learned folks exchanging ideas.  For any kind of advanced programming, SE is essential.  Get to know it!  The section on English is described as "English Language & Usage Stack Exchange is a question and answer site for linguists, etymologists, and serious English language enthusiasts.")   

Here's what is written in that Exchange (by Tucker):  

David Foxon's 1991 Pope and the Early Eighteenth-Century Book Trade is the canonical Work on this Topic. 
As to when the rule of capitals for nouns was inherited into English, that perhaps can never be known. 
Since German capitalizes every noun there is speculation that this rule has been inherited from there, perhaps via Johannes Gutenberg and his famous printing press via the Gutenberg Bible (note that the Gutenberg press is not the first of its kind as the Chinese and Koreans already had this technology as early as 1000s). This could be where the Germanic rule of capitalizing nouns may have originated since the Gutenberg (and subsequent presses) were all German in origin and their language and grammar rules may have influenced the rules of printed words far and wide. 
Capitalized nouns were a common occurrence and can be seen in many instances prior to the 1730s and seems to be a shift at this point. From this first issue of the Gentleman's Magazine published in 1731. Every noun has been capitalized. This heavy use of capitals seems to be common especially in the printed word. David Foxon wrote in his book entitled Libertine literature in England, 1660-1745 that "... the vogue for heavy caps may be associated with the eighteenth-century culture of sensibility." Also, "Heavy caps also seem to be associated with the more chatty, conversational style of prose that comes into fashion in the late seventeenth and early eighteenth centuries." 
There is a steady drop of capitalizing every noun as can be seen by this volume of the Gentleman's Magazine printed in 1744. This starts to look familiar with printed and accepted usage by today's standard.
And do the US and the UK differ in capitalization?  Sure.  My query:  

     [ differences between US UK capitalization ] 

led me to the Wikipedia entry on Capitalization, which has an extensive listing of the differing practices.  Oddly, while acronyms have historically been written in all-caps (e.g., NASA), British usage is moving towards capitalizing only the first letter in cases when these are pronounced as words (e.g. Unesco and Nato), reserving all-caps for acronyms made up of pronounced letters (e.g. UK and USA).

3. What are those funny connectors between characters?  What are they called, what pairs of letters have them, and how can I get those on MY computer?
This one is easy.  My query: 

     [ connector between letters ] 

tells me that these small strokes between characters are called ligatures.  A quick Image search for [ ligature ] shows many different kinds.  Here's a sampler:  

Notice that ligatures also include letters that overlap (such as the OC combination above) and letters that blur together (like ӕ).  

Now, how do I get these in MY documents?  

The simplest way when writing on the web (such as, when I'm writing this blog), is to find an resource that has them all.  

The truth is that I tend to use a specialty app (like Illustrator or Word) to get the character, insert the special character in a blank document, then copy/paste it to my target document.  This gives a good deal of control over what kind of character you get.  

To get a ligature character in MS Word: 

1. Have a font that includes ligatures. You probably already have several, even if you don’t know it.  Explore a bit and you'll quickly discover which ones have them (big hint--they tend to be older fonts such as Palatino Linotype).  

2. In Microsoft Word, click “Insert" then "Symbol."  

3. On the “Symbols” tab, there should be a “Subset” dropdown list on the right. If there’s not, pick a different font from the “Font” list. 

5. Scroll down the “Subset” list until you find a subset called “Alphabetic Presentation Forms.” Or, easier still, click in the list and then press the “A” key on your keyboard until you come to “Alphabetic Presentation Forms.”

6. Somewhere in the characters displayed will be some ligatures, probably fi and fl but maybe others as well. Click one of them, then click “Insert."  

To get a ligature character in Google Docs:  

1. To insert a special character, do Insert>Special Characters> 

2. Then, do a search for "ligature" in the pop-up menu that appears (note where I entered "ligature" next to the magnifying glass...

Once there, you can insert whatever characters you like, such as: 

ij Œ œ ӕ Ӕ ff fi fl ffi ffl ſt

Now you can do your typographical best! 

Search Lessons

1.  When searching for evidence, don't forget about checking the primary sources yourself!  As you see above, it's pretty straightforward to get pages of text from different time periods by search in Google Books and limiting the date of the books.  As you can see from the above sequence, capitals varied a good bit over time. 

2. Often a comparison between sources can be useful.  In our case, looking at different contemporary copies of the Declaration of Independence shows us that the capitalization practices varied across copies published in the same year!  (And it wasn't just one or two letters either; the number of differences suggest that people had a lot of variation in what they thought was acceptable.)  

3.  When searching for the history of something, be wary of received folk wisdom.  Be careful when looking through your sources--you really want something that's credible and provides a story that you can second source someplace else.

Search Challenge (8/19/15): Why all the crazy capital letters?

When in the course of human events... 

... it becomes necessary for one person to understand something strange, weird, or unexpected, they often turn to a Search Engine.  

And with that Sentence, I illustrate the Challenge for today.  

As you probably noticed, my use of capital letters was a bit odd in the preceeding couple of sentences.  These days, we understand what gets capitalized:  Initial letters of sentences, proper names, words for emphasis, and specialty terms (e.g., "Search Challenge").  

But this wasn't always the case.  If you look at just the text of the US Declaration of Independence from the website, you'll see: 

IN CONGRESS, July 4, 1776.
The unanimous Declaration of the thirteen united States of America, 
When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.

Note where the capitals are in those few transcribed sentences:  "Declaration" and "State of America" (and most notably, not "united").  

Seems odd. 

But it gets even weirder when you look at one of the earliest copies of the Declaration (which I've marked up here to point out some of the interesting and odd typography). The capitals seem scattered almost at random:  

All of the f-shaped characters are, of course, the "Long S" character.  (It's interesting to note that "happiness" is spelt "happineſs." And yes, I used the correct character there.)  

But notice the pattern of capital letters.  In the version, "Events" isn't capitalized, but "Course" is!  On the other hand, in the earlier version, lots of other words get capitals (highlights in pink rectangles).  Course, Events, People, Political, Powers, Earth, Station... they're all capitalized.  

And then there are all of the little "connectors" that link two letters (some of which are pointed to by my red arrows).  What's up with that?  

This leads to today's Challenges: 

1.  What's the story with the Capital letters in the 18th century?  Were they just throwing in caps at random, or is there a Rhyme, and Reason to their capitalization?  
2.  Related: How / why / when did our practice of capitalization change to what it is currently?  (And, for extra credit, do other countries follow the same pattern of capitalization that we English-speaking types do?  For that fact, is the practice of capitalization the same in the US as in the UK?)  
3. What are those funny connectors between characters?  What are they called, what pairs of letters have them, and how can I get those on MY computer?

As is our Usual Practice, please let us know HOW you found the Answers in the comments below.

(And, just to remind you: The "Danish optical instrument" Challenge is still open.  I have some new leads, but I'll write to you tomorrow about that.)

Answer: Finding things from other cultures

Let's talk about the simplest first.  

Clearly, figuring out Challenge #2 from last week (from whence do these posts come?) was pretty straightforward.  So let's talk about that first.  Recall the Challenge: 

2.  What are these posts for?  Who built them, and why?   

Click on each of these images to see the photo in full resolution.  
As several SearchResearch readers quickly figured out by examining the EXIF data (see one of our earlier discussions about reading EXIF data) that these posts/sculptures are very near the California coastal village of Gualala (map link).  The lat/long I extracted from these images is 38.757103, -123.517256 

Looking at the map, I saw "Gualala Point" there, so my first query was: 

     [ Gualala Point sculpture ] 

which quickly led me to the Sakha Cultural Festival (Wednesday, June 18 thru Sunday, June 22, 2015) and tells me that these posts are actually created by Sakha woodcarvers and are called Serge, which act as both a horse hitching post as as a ritual object for ceremonies.  They were installed at the Gualala Point Regional Park the week of June 15 and dedicated on Sunday, June 22. Visit the web page to see more images of the serge and video of the carvers making them.  (Apparently there's also a set of serge at Fort Ross and the Gualala Art Center, although I haven't seen them.)  
The carvers are from Sakha, a region of Russia that is roughly the size of India, but holds only about 100K people.  The Yakuts people are from Sakha, and were early settlers in this part of California in the 1820s where they hunted and did lots of work with other Russian immigrants, trappers, and traders. 
In any case, this wasn't too difficult to figure out.
Search Lesson:   When searching for a localized target, grabbing the EXIF metadata with lat/long and THEN searching for other obvious features (e.g., the name of the park the target is located within) can lead to a rapid resolution.  Be sure you know how extract EXIF from image--it's immensely handy.  

HOWEVER... the mystery of the first Challenge from last week continues to grow.  WHAT IS THIS THING?  
As you recall, Elin told us the story of having seen a striking optical device when she was just a kid in Denmark, and wondered if we could help her find it.  So far.. we haven't had success.
Her Challenge was: 

1.  WHAT is the name of this device that Elin describes?  Can you figure out who made (or still makes) them? 
And since this is so up-in-the-air, I'm going to leave this Challenge open for a bit longer.  Like many of you, I've been poking various Danish friends, hoping that someone will know a Danish optician or ophthalmologist, OR someone can connect me with a Danish museum of optical instruments.  
But so far, no luck.  
I've even tried searching .DK site in Danish (using Google Translate to give me query terms like antik Optiker enhed , and Optiker udstyr... but those didn't pan out.  I suspect that some of the clues we've found (e.g., the cobalt blue background, or the image of the keratometer) will be useful... we just don't know how yet. 
So, carry on SearchResearchers!  Neither I nor Elin know the answer.. yet! 
Search on!

Update on the Danish optical device

I ran a few images of devices ... 

that might have been found in a Danish opticians office past Elin over the weekend.  Here is the one that she said seemed most-like the one she remembered.   This is a keratometer from the 1950s.   

In particular, it was a monocular device.  The biggest difference is that Elin recalls seeing blue and red rings, a bit like the duochrome test.  

One optometrist's page tells us that the duochrome test is often red-green, but that blue may be substituted for green on occasion.  That same page also tells us that circles are sometimes used in the test, and they're called Verhoeff's Circles.  

Don't know if this will solve the Challenge or not, but I thought I should give you this additional clue!

Search Challenge (8/12/15): Finding things from other cultures

Often the most difficult ... 

... Challenges come from friends who are Googlers (so they've already done their own searching on the topic), and who are still stumped by what they seek. 

Difficult Challenges are also characterized by not knowing where to start.  That was the case a couple of weeks ago with the oddly-shaped industrial roof-line, and it's definitely the case when you're searching for something that's NOT in your own culture.  In Search Challenges like this, you literally don't know where to start, and that makes the searching harder than usual.  

Two we have two Challenges, one that's difficult (from a Danish Googler friend) and one that's pretty straightforward, but also comes from another culture.  

Challenge #1 comes from my friend Elin. She's a Google Researcher from Denmark who wrote to me with the following question:  

I am looking for the name (and detailed function) of an instrument I remember from my childhood, in  early 60s.
Back then, it was common that opticians had this mounted on their storefront window, for the education and amusement of bypassers on the sidewalk, and most likely also to bring people into buy new frames and lenses.
When you looked, with one eye at a time, into a scope, you would see colored circles, I think it was a blue circle with a larger red one behind. Deformity in the circle was an indicator of astigmatism (as far as I remember), but perhaps there were other aspects as well.
As kids, we loved to "test" ourselves when we walked by the store.  Maybe we were early quantified self'ers...  
I have asked around among people aged 50-60, but no Americans seem to have experienced this. Some Danes and Germans remember this, growing up in urban cities with lots of store fronts.  But nobody seem to remember the name and exact functionality.

1.  WHAT is the name of this device that Elin describes?  Can you figure out who made (or still makes) them? 

This week's second Challenge comes from my travels in northern California.  While on a trail walk, I came across the following fascinating place.  Here are my pictures from that remarkable field of beautifully carved wooden sculptures with images of horses.  I somehow doubt they were put here by the Dothraki.... 

Click on each of these images to see the photo in full resolution.  

You can see why I was so astonished at running across these posts, kind of in the middle of an open field.  What?  How?  And furthermore, Why?  

2.  What are these posts for?  Who built them, and why?  

Remember to let us know HOW you found the answer, what you did to make your research path work out!  

(Caution:  Neither Elin nor I have the answer to Challenge #1, so we'll be searching as well this week.  But I do know that Challenge #2 is fairly straightforward. But if the SRS Regulars aren't making any headway by Friday, I'll post a hint in an update.)  

Search on!

Video content from the course

We just finished running... 

... the updated version of the course.  As you might guess, it's a lot of work to pull all of this content together, making the videos, writing the content, and so on.  I'd like to make it as available as possible to the most people.  

So, below I've put all of the videos from that course into an easy-to-use table.  

This is the master list of videos along with a short description of the topic for each.  They’re all around 5 minutes long, so any of them are easy to work into your program.  

And best of all, they’re all labeled as Creative Commons CC BY-NC, so go wild!  

(The BY-NC label that means you can remix, tweak, and build upon these videos non-commercially; note that your new works must acknowledge my original work (a link is fine),  and be non-commercial).   

The texts and slides will are still in-process, but I'll post a link to them in the blog as well (just as soon as I finish them up).
