RSVPed Attending MATH X 451.43 Introduction to Algebraic Geometry: The Sequel
Algebraic geometry is the study, using algebraic tools, of geometric objects defined as the solution sets to systems of polynomial equations in several variables. This course is the second in a two-quarter introductory sequence that develops the basic theory of this classical mathematical field. Whereas the fall-quarter course focused more on the subject’s algebraic underpinnings, this quarter will concentrate on geometric interpretations and applications. Topics to be discussed include Bézout’s Theorem, rational varieties, cubic curves and surfaces (including the remarkable 27-line theorem), and the connection between varieties and manifolds. The theoretical discussion will be supported by a large number of examples and exercises. The course should appeal to those with an interest in gaining a deeper understanding of the mathematical interplay among algebra, geometry, and topology.
I’m definitely attending the Winter Quarter!

I ran my domain through IndieWebify.me. Almost all of the rel=“me” links either don’t link back or couldn’t be fetched. The following work perfectly and can be used with the IndieAuth authentication plug-in. GitHub Flickr Goodreads Twitter That’s 4 out of 43.
Khürt , The majority of them don’t link back because the silos (like Keybase, Instagram, and Medium which you mention) aren’t putting the rel=”me” microformat on the URLs in your profile like Twitter, Github, and Flicker do. If you view the page source for those silos, you’ll see that they list your URL, but don’t have rel-me’s pointing back at you. Sadly, you can’t control these, though you could file issues with the sites that don’t to encourage them to.

The indiewebify.me site has a parser that is looking at the two sites to see that they not only point at each other, but it requires that the two links have the rel=”me” microformat on them. Most don’t, but this doesn’t mean too much in practice. Whether or not they both have rel=”me”, the only way both sites could point at each other indicates that you “own” or control them both. Kevin marks has proposed/built an interesting decentralized verification service based on them. His version is certainly much better distributed than Twitter’s broken verification set up.

Other than having a stronger two-way ownership indicator, what do you get out of them? As you mention, some have the ability to be used with IndieAuth. Those that can be used with IndieAuth are relying on the service (like Twitter or Github) having a OAuth implementation for signing into their services. This allows an indie site to piggyback on another services’ OAuth implementation without having to go through the trouble to build one themselves, which can be a lot of work to do, much less do correctly (securely). Most of the services you see not linking back not only don’t add the rel=”me” tag, but they also don’t support OAuth, so you wouldn’t get too much more out of having the correct reciprocal link anyway.

Incidentally, one of the benefits the rel=”me” links do have is that they allow you to use your website to log into the IndieWeb wiki to participate directly in that part of the community. (Give it a try!)

Some services like Brid.gy get around services like Instagram or Facebook not having a physical rel=”me” microformat because they’re relying on looking at the appropriate data (usually via API) on your profile page to see if it links back (either in your website field or typically in your bio).

Don’t be overly concerned that the vast majority of sites appear not to link back even if you’ve got links on both pointing back. (And if you think your batting average is bad with only 4 of 43, just imagine how many of my 200+ sites do?!)

If you want to see an interesting tech-forward application of rel=”me” and the XFN friends network, take a peek at Ryan Barrett’s Indie Map which he unveiled over the summer:

Some of these building blocks will likely add a lot more value later on as more and more sites explicitly indicate their relationship to and from each other.

Token Generation Events (TGE’s) have proliferated as an alternative means of funding a Start Up. There are some compelling opportunities for the entrepreneur over conventional VC and Angel options. This is the (unfolding) story of how one navigates a fast changing landscape where the SEC looms, Token Economics is religion, Skepticism is growing, Exchanges can help or hurt you and potentially tens of thousands of people in dozens of foreign countries are your investors. I’m all in and I’ll tell you why….. Friday, December 8, 2017, 8:15 AM to 9:30 AM Cross Campus, 85 N. Raymond Avenue, Pasadena, CA Venue is located on the 2nd floor. Free street parking until 11:00 am; except where valet signs are posted. 90 minutes free parking is also available at nearby parking lots. Topic: Building a Blockchain based Business and funding it via a TGE
I met Michael Culhane at today’s coffee and he’s quite interesting. I’ve been meaning to delve into some of the blockchain technology a bit despite some of the dreadful things I’ve been hearing about the underlying viability of using it for some of the off label use. I hope to see everyone there next Friday.
