At last I get to work on the latest, ninth episode of The Puerto Rico Connection. But on the New Media class on Thursday 25th, there was no connection. Alan tried his best to give a talk to my students. Unfortunately the networks did not collaborate. My students and I tried every possible route: Wifi, Ethernet and cellular hotspots, to no avail.
Blame the Internetz!
Until Alan found the culprit,
We know who to blame. El Orange Chupacabra

In the previous post (Preparing for the 9th episode) there are the ideas Alan and I played with during our fine conversation. In fact, he was smart to gear it towards the recent first-image-ever of a black hole. From there, it was a freewheeling talk on what’s a photo of a black hole vs. an image; the singularity idea of a point in spacetime where not even light can escape from; and the digression to the limit when we discussed what would happen if we reduced the podcast’s timing to zero, little by little? It’s a joke, but mathematicians use this “limit” idea pretty often and with beautiful results. So, how would we open and close a recording which lasts exactly zero point zero time? If it were 0.0001 seconds, we might image being very very very quick. But with no time at all, would it still make sense? A line, if you reduce its length progressively up to zero, will become a point. It makes sense as a point but it’s difficult to see a point as an abstract line taken to the limit. But a recording? Of course it’s non-sense, but one it was fun to talk about!
Anyhow, see the previous post to read a bit more on this.
On the episode we talked about other stuff, of course. No spoilers here. And we said we would publish here the links we collect and share and we’d like to discuss on the air. We didn’t discuss them on this episode, though, since we hadn’t had a chance to read them beforehand. So, it’s for next time. Here, I’ll paste a copy of the feed coming from the shared tag prcon:
where the tab=153 means to get only the recent links. Now, the diigo page for these links (diigo.com/tag/prcon?tab=153) would not return the description of each link. Fortunately, the Firefox add-on Want My RSS does. And this is the result.

A lot of companies are trying to make it easier to use artificial intelligence, but few are making it as simple as Lobe. The startup, which launched earlier this year, offers users a clean drag-and-drop interface for building deep learning algorithm…
“Learning is Earning”? Connecting learning outcomes with a measurement of graduates’ earnings is dangerous; linking or correlating that with faculty’s performance is plainly and morally wrong.
“Why we’re building Refind and giving away 1 billion coins.” First Web discovery service I’d like to discuss here & in a next episode of the podcast.
Surprising that we still have to discuss simple, obvious stuff. Alan makes a compelling case on grading; why we consider students’ work as evidence of their mastery of a discipline, a concept, or a creative process. Of course, this does not mean at all grading the student: it’s the student’s work that gets considered. Can’t believe there are people who think like “grading the student”. Grading actually does not makes much sense, in a knowledge-centered world: Would you be on the operating table of a surgeon who got a “C” average? What does the “C” means? Can she operate or not? Can he pilot a plane or not?
“Build ideas mindfully. Save content, create collections, and connect ideas with other people.” Second web service to discuss. This seems like a sophisticated bookmarking service, and I like bookmarking. Who can tell me more?
“WorkFlowy is a single document that can contain infinite documents inside it. It’s a more powerful, easier way to organize all the information in your life.” The plain idea of an “infinite document” is very appealing to me. Likewise, the recursivity of such a document–cotaining infinite other docs within–is fascinating. Would it be useful? How?
“a machine translation service that produces translations of unprecedented quality” A possible alt to google translate? DeepL
Below are several mathematical typefaces which are inspired by mathematical theorems or open problems. Most include a puzzle font: reading them is itself a mathematical puzzle.
In these fonts, each letter or digit or ampersand can be dissected (cut into pieces such that those pieces re-arrange) into a 6 × 6 square. The dissections all happen to be polyomino dissections, and they allow translation, rotation, and reflection …
The February 1945 issue of Radio-Craft magazine included an article titled “Radio Audience Meter” which looked at the machine that was revolutionizing audience measurement. First installed in homes on a trial basis in 1939, the Audimeter was placed …
I did not edit the links’ code at all, so it seems with a simple copy & paste we got a reasonable format on this post. Now it’s just a matter of opening up Hypothes.is in this post and we all can annotate it.
And now, enjoy Episode Nine!
