HP’s Ink Subscription Has DRM That Disables Your Printer Cartridges

By Stephen Downes - Stephen's Web. HP’s Ink Subscription Has DRM That Disables Your Printer Cartridges
Josh Hendrickson, How-To Geek, 2019/02/11
It turns out that the idea of putting digital rights management (DRM) into your printer ink is as bad as it sounds. "Here’s the kicker: if you cancel, your ink stops working. You read that right; as soon as your billing cycle ends the printer will not accept the ink anymore." You're also sending a whole lot of data to HP - page count, page type, and more. That's because there are limits on the number of pages you can print as well. More...

Visual Studio Code Can Do That?

By Stephen Downes - Stephen's Web. Visual Studio Code Can Do That?
Burke Holland, Smashing Magazine, Medium, 2019/02/11
Visual Studio Code is my new favourite text editor, and has been responsible for a bit increase in my learning curve over the last month. It combines three core functions - file management (including version management with GitHub), text editing (with formatting that supports everything, even Perl), and command line terminals (so I can usefully write and test scripts in the same environment, and then publish in Docker or whatever). And as this article shows, there's a whole lot more for power users. Including (just announced this week) something called Live Share, which will allow multiple developers to work on the same project at the same time. It's all open source, written in Node, and compiled for the desktop using Electron. More...

Mobile Learning: The Next Step in Technology-Mediated Learning

By Stephen Downes - Stephen's Web. Mobile Learning: The Next Step in Technology-Mediated Learning
"Learning," writes Ellen Wagner, "is a deeply personal act, best facilitated by relevant, reliable and engaging experiences, yet many teaching approaches still rely on more impersonal 'command and control' models that include an instructor in charge, specific goals to be met and criteria to be mastered." Mobile learning devices stand poised to change this, she writes. "With mobile technologies, training now accommodates people instead of people working to accommodate training." Well... except for the size thing. And the proprietary technology. More...

FlashMeeting - the YouTube of Videoconferencing?

By Stephen Downes - Stephen's Web. FlashMeeting - the YouTube of Videoconferencing?
It remains true that Flash is the best means to show video on the web (which is sad, when you think of it - because there are so many better alternatives, but the companies behind the standards could never agree on something everybody could use). The same may hold true of videoconferencing. "FlashMeeting is not a videoconference system in a traditional sense. The one that is speaking is actually always broadcasting her video and audio stream for other participants. All the participants may ask for turns and when you ???stop broadcasting" the turn moves automatically for the next in the list". More...

EduRSS 0.2 Is Back

By Stephen Downes - Stephen's Web. EduRSS 0.2 Is Back
Edu-RSS is in operation once again, harvesting blogs and sending out pages and RSS feeds. Here is a list of the feeds harvested by Edu-RSS. I am now producing several output pages (and corresponding RSS feeds):
On this site, Edu_RSS runs several different lists:

(Click on the orange RSS icon in the address bar to get the RSS feed). Also related to this is the arrival, once again, of my Research Topics pages. These are also showing up as 'tags' on individual posts both in Edu_RSS and in this newsletter. I'm still working on that a bit - the topics will be displayed in categories some time in the future. And RSS feeds for the topics will be available again. Still some bugs in the system (especially in the auto-tagger). In the meantime, I hope you enjoy the way I've incorporated the Wikipedia content into the pages.
One thing to note. Edu_RSS, when it harvests, collects all the links cited in given posts. This will be used to track conversations and to rank pages. So far so good - but many feeds (especially WordPress feeds) only distribute short summaries of about 300 characters (Edu_RSS itself only retains 1000 characters, but only after analyzing the full content). I do not retrieve the original web page. So if you are distributing only a summary in your web page, the sites you link to are not being recorded. Just so you know.

Face-to-Face Trumps Twitter, Blogs, Podcasts, Video...

By Stephen Downes - Stephen's Web. Face-to-Face Trumps Twitter, Blogs, Podcasts, Video...
I used to lead large demonstrations when I was younger - my favourite was a March 5 demonstration against tuition fee increases in Edmonton. Though the temperature was -30, we convinced more than 5,000 people to march more than a kilometer through the cold, over the High Level Bridge, to the legislature. Someone once asked me, "Why do you do this? Demonstrations never hange the minds of government." I responded, "That's true. But it's not for them. It's for us. Remember how good we all felt after showing our strength and conviction like that? That's why we had a demonstration." Kathy Sierra makes the same point about conferences. More...

I still think the Wii is bigger than 2L. Why? "wii.js (via) A JavaScript library that lets you detect the Wii browser, and provides easy hooks for reacting to keys pressed on the Wiimote." Of course, what we really want is a 3D distributed Wii. More...
