What we learned from designing an academic certificates system on the blockchain

Stephen Downes' OLDaily - Tue, 06/07/2016 - 11:00


Juliana Nazaré, Kim Hamilton Duffy, J. Philipp Schmidt, Medium, Jun 07, 2016

Some of the issues: the choice of bitcoin rather than ethereum; using a link to view certificates rather than public-private key pairs; leaving the possibility of certificate revocation in the system; privacy and transparency around blockchain; the right of the user to curate the certificates being shared; and whether the use of certificates can be tracked. There are three repositories: the certificate schema, defining the data structure;   the certificate issuer; and the certificate viewer. The developers have released version 1 of the code  to the community.

Internet Trends 2016

Stephen Downes' OLDaily - Mon, 06/06/2016 - 16:00


Mary Meeker, Slideshare, Jun 06, 2016

Is it time for Mary Meeker's internet trends report already? Yes it is, and this year's analysis is full of telling charts and statistics. Ina Fried identifies the major takeaways  from this year's report:

  • The internet itself is seeing slowing growth. 
  • In five years, at least 50 percent of all searches are going to be either images or speech.
  • Messaging apps, with context and time, have a chance to rival the home screen as the go-to place for interaction.

This list would explain why Facebook is attempting to force me to use its messaging app on Android (instead of my web browser, which can be turned off). More: a short video  where Meeker says many online ads are ineffective. Also, interviews and much more from the Recode conference.

35 Interface Innovations that Rocked Our World

Stephen Downes' OLDaily - Mon, 06/06/2016 - 14:00


Xerox, Jun 06, 2016

This list reflects a series of rethinkings of interaction space in (mostly) digital technology. It's interesting to go though the list and ponder not just what the new interfaces allowed, but also what they replaced. For example, the rotary dial on the telephone replaced the need to tell the operator which number you wanted to be connected to. The mourse replaced the need to use arrow keys to move a cursor.

Medium acquires Superfeedr

Stephen Downes' OLDaily - Mon, 06/06/2016 - 14:00


Julien Genestoux, Medium, Jun 06, 2016

I found this claim interesting, especially from the perspective of my talk today: "We consume the web from mobile devices, we discover content on silo-ed social networks and, more importantly, the base metaphor for  the web is shifting from space to time." It's not unusual, though, to hear this perspective with respect to RSS; it reminds me of Dave Winer's 'river of news' concept. The otbher thing, of course, is the renewed interest in RSS from Medium, which is a rapidly growwing platform in its own right. But with Superfeedr, and especially PubSubHubbub, Medium is acquiring a whole distribution network.

The Final Frontier: Space

Stephen Downes' OLDaily - Mon, 06/06/2016 - 14:00
[Slides][Audio]

I compare two metaphors for learning: first, time, as the dominant metaphor, which is a linear and ordered progression toward a goal; and second, space, which is a non-linear exploration of a domain. I also examine the sort of tools. technologies and learning supports we should be thinking about when think of learning from a space-based perspective.

Rick Fast', O'Reilly, Jun 04, 2016

More on Docker. "Docker has grown from a convenience wrapper to encompass an entire architecture. Learn how Docker's major components are related to each other." This is a short video highlighting the major elements of the Docker architecture. Really just a set of slides with an audio track.

Introducing HyperDev

Stephen Downes' OLDaily - Sat, 06/04/2016 - 12:00


Joel Spolsky, Joel on Software, Jun 04, 2016

So this looks interesting. "HyperDev  is going to be the fastest way to bang out code and get it running on the internet. We want to eliminate 100% of the complicated administrative details around getting code up and running on a website." I've set up a very simple page here. It took me a couple minutes. But I think I could spend a lot of time with this - already someone has coded a Skype Bot  for it. Note that this is a beta release and that there are going tl be interruptions in service.

Want to Do Corporate Innovation Right? Go Inside Google Brain

Stephen Downes' OLDaily - Sat, 06/04/2016 - 12:00


Greg Satell, Harvard Business Review, Jun 04, 2016

I imagine some time in the future we'll be reading about why Google's strategy failed and that the sort of thing it did doesn't work any more. But today is not that day, and as this article suggests, Google is currently riding high on an innovation strategy that is hard to implement but which seems to work. "What makes Google special is the way it’ s been able to integrate an entire portfolio of innovation strategies into a seamless whole. Product managers focus on customers needs. Researchers go where the science takes them. Engineers working on 20% time projects follow their passions. Anybody who wants to can adopt one or more of these approaches."

Creating a CSS Curtain Opening Effect

Stephen Downes' OLDaily - Sat, 06/04/2016 - 12:00


Geoff Graham, CSS-Tricks, Jun 04, 2016

There are thousands of lessons like this on the internet, not part of any official repository, but widely shared and widely used. This one is shared by a site called CSS-Tricks. But the magic is worked by an application called CodePen, which has been around for several years. Here's the CodePen for this article. CodePen takes the script that was entered by the author and executes it in a window that can be displayed on an HTML page.

The Battle Of Multiple Learning Management Systems: A Learning Application Developer’s View On LTI

Stephen Downes' OLDaily - Fri, 06/03/2016 - 15:00


Dov Friedman, eLearning Industry, Jun 03, 2016

This is some of what we were working with when we developed the Personal Learning course (sadly no more MOOCs until I figure out a way to pay for them). The idea was that we could connect to any LMS using our Arke prototype - this is how we were connecting to the OpenEdX installation using the personal learning environment. Ultimately, of course, we would have connected with the list of LMSs just as this application is - "Rather than building a unique solution for each Learning Management System, learning applications can now be connected with almost all EDU Learning Management Systems using one standard."

The OA Interviews: Michaël Bon, Founder of the Self-Journal of Science

Stephen Downes' OLDaily - Fri, 06/03/2016 - 12:00


Richard Poynder, Open and Shut?, Jun 03, 2016

"Right now," says Richard Poynder, "the open access revolution is stalling, and before it will be able to move forward again it will be necessary to recover territory that OA advocates are currently giving away to publishers." Hence this interview (28 page PDF) with  Michaë l Bon, who launched a new open-access publishing service called the  Self-Journal of Science  (SJS). Bon argues "OA advocates have been trying to do things back to front, and as a result have played into the hands of publishers....  By contrast, says Bon, SJS is focused on exploiting the new environment to reinvent scholarly communication."

British-Palestinian schoolgirl expelled from public speaking competition

Stephen Downes' OLDaily - Fri, 06/03/2016 - 12:00


Middle East Monitor, Jun 03, 2016

When I was in grade five I won the public speaking competition with a speech about Sir Frederick Banting and the discovery of insulin. It was uplifting and mildly patriotic. But when I was in grade eight I won the same competition with a scathing and powerful speech against the Vietnam War. I won the following three years as well, finishing with "How to be a dictator in give easy steps". The ability to write and deliver a speech is a powerful force, and I'm glad it was developed in me. So I feel for  Leanne Mohamad, a 15-year-old student at Wanstead High School in London, who won a regional final  of the Jack Petchey Speak Out Challenge for a  moving speech about the Palestinians called  ‘ Birds not Bombs’ , but was barred from participating in the  final. She should be allowed to speak.
