Boston Book Festival this year – dinner and a date
Sunday April 03rd 2011, 10:20 am
Filed under: chain-gang,Glory, glory, glory,poetic justice
Save the date: the Boston Book Festival is set for Saturday, October 15 this year on Copley Plaza.  It’s a lot of fun, and you may get to meet some of your literary heroes 🙂

I have gone to the BBF the past two years and loved it; it makes me regret not becoming a writer. Last year I volunteered at the event, helping set up their public wifi; they’ve also held a tent for OLPC for the past two years, where we’ve recruited a few great collaborators.  It is a literary bazaar, warmly supportive of local authors and businesses — with hints of festival, conference, and educational showcase.   All of the events are free, but it was hard to get into the most popular author presentations — seating was packed, and nobody wanted to leave when sessions ended!

The festival is supported by the Boston community, and this year they’re hosting a fundraising dinner for the festival, as part of a fundraiser for the event. (It’s nice to see Cambridge helping out its big brother.)  They are also reserving seats at the big events for donors, with VIP passes.  Please consider volunteering for the event or coming to this dinner to support and learn about it.

La Voz Del Mako

Some things are too good to mako up: The prison-blogging project La Voz Del Mako, “un espacio libre para los reclusos” at Centro Penitenciario de Albolote in Spain, apparently began life as a newspaper of the same name a dozen years ago. The current director of the prison said, in setting up the blog, “I wanted to open more than prison.” It’s not quite Between the Bars, but it looks like an interesting cloistered-community-wide effort.



Editor-to-Reader ratio on Wikipedia: a visual history

After early exponential community growth, editing on Wikipedia has slowed recently. The number of readers, on the other hand, grows steadily. Over the past 3 years, the number of active monthly editors in all languages has declined by 12% (and twice that in English). But the effective change in active editors per reader may be 4x as large.

This change in how many readers become editors points to both a problem and a short-term solution: On the one hand, we have many more people coming to the projects who don’t know they can edit, find no reason to do so, or are discouraged before becoming active. On the other, we reach many more people than in the past, so effective changes in messaging, tools, or policy have a larger impact.

Mako and I were discussing this last night, leading to some back-of-the-envelope calculations (using some of the many great stats resources the Foundation maintains) and a heady R + ggplot session, which turned into a beautiful post on copyrighteous:

Unlike all those other [encyclopedia projects] Wikipedia is the encyclopedia that anyone can edit. Wikipedia is powerful because it allow its users to transcend their role as consumers of the information they use to understand the world. Wikipedia allows users to define the reference works that define their understanding of the their environment and each other. But 99.98% of the time, readers do not transcend that role. I think that’s a problem.

Wikipedia loves editors: 2011 campaigns?
Saturday February 05th 2011, 10:16 pm
Filed under: chain-gang,fly-by-wire,Glory, glory, glory,popular demand,wikipedia

Wikimedia had a terribly successful fundraising campaign ths year, with a team of stats-loving traffic and feedback analysts learning a lot about our reading audience and how to connect with them. There was diverse support for the idea of running some banners to promote donating time and expertise and edits as well as money, and some general-purpose “discover Wikimedia” banners were run the first week of January, but this was soon overtaken by preparations for the (wickedly fun) 10th anniversary celebrations.

We should do more of this. The idea of inviting people more explicitly to edit, and running campaigns dedicated to this, is more fundamental to the nature of Wikipedia than fundraising itself. We should be thinking about all year round, spending as much time and effort campaigning for meaningful content contributions as we have for funds.

What would that look like? Here is one idea: WikiProjects could be encouraged to write copy for their own banners, from a hook to a detailed call for what they need. These would be run for a % of new visitors proportional to the project’s capacity to absorb new contributors. A few generic projects would be geared up for a larger influx of editors, and established editors would be asked to help work with those newbies (and to set up comfort zones where they can find and help one another).

The generic projects would ramp up slowly; with one month’s newbies helping welcome those who came the next month. Some new policies regarding working with newbies would need to be proposed on the major wikis, possibly with a group like the original Fire Brigade dedicated to helping the ambassadors and welcomers with the extra load. And the specific WikiProjects could continue to draw in as many new editors as they want, and could try out different messages to attract just the right sort of reader (including efforts at targetting specific kinds of readers).

What do you think? How would you reach out to readers if you could change the way the site looks? (What ever happened to the idea of highlighting the “edit this page” tab?) Over 1% of people who saw the best fundraising messages clicked through them — imagine what we could do if we showed all of those people that they could really edit.

…and when they make loose with a few orders of magnitude.

Rouder and Morey critique some recent work by Bem on “Feeling for the Future”:

[O]ur assessment is that Bem’s experiments, collectively, provide some evidence of psi phenomena, but not enough to sway the beliefs an appropriately skeptical reader…

…There is [a] surprising degree of evidence for the hypothesis that people can feel the future with emotionally-valenced nonerotic stimuli, with a Bayes factor of about 40. Though this value is certainly noteworthy, it is several orders of magnitude lower than what is required to overcome appropriate skepticism of such implausible claims.”

The framing of the questions and hypotheses here is most amusing, and worth a read. Rouder’s face sums up this whole debate.

Hat-tip to Cassandra Vieten at HuPo.

On Graphene
Sunday December 26th 2010, 12:16 am
Filed under: chain-gang,Glory, glory, glory,Too weird for fiction

Graphene is one of the most remarkable substances in the world. Physicists Andre Geim and Konstantin Novoselov won the Nobel Prize for their work to manufacture single-layer sheets of it only six years after their first success.

Now it is entering mass production, and being considered for the sort of applications that currently rely on nanotubes. It might also be suitable for very different macro-scale tasks, as sheets of graphene can theoretically be arbitrarily broad (while just one atom thick), once a suitable production process is worked out.

In practice, it is still hard to produce monolayer sheets of graphene, but we are making thinner and thinner ‘platelets’ by exfoliating them from larger chunks. Many current applications depend on the bulk surface area available for interaction with the environment, and platelets are often marketed in terms of their surface area per unit weight (in m^2/g).

The properties of commercially produced graphene are 1-2 magnitudes less than the extreme values measurable with pure monolayer sheets. So on top of the practical economic applications today, there is a decade of Moore-like improvement to look forward to. Costs of production vary according to purity: low-grade graphene (platelets 3-10 layers thick and a few dozen microns wide) are available for under $300/kg, while higher-quality graphene (1-3 layers thick, hundreds of microns wide) can range from $10/gram to $100/gram, and only in small quantities.

Finally, my favorite factoid about graphene (out of MANY): you can use a sheet of it to directly measure the fine structure constant: each layer absorbs πα (that’s pi times the fine structure constant) of light that passes through it!



olpcMAP Sprint: put XO communities on the map!

olpcMAP is ready for launch, and we’re hosting a map sprint at OLPC headquarters this week. Come help us design the next iteration of the map, and add your favorite projects to it. And encourage everyone you know who works on an OLPC project to add themselves as well — this map is designed to be a reusable repository for map data, so anything stored here will be easy to query and use in other map contexts in the future.

If you can only join for only part of the mapping sprint, try to come on Tuesday Dec 28, when you will get to see a special screening of Audobon Dougherty’s study of the impact of Internet access in rural Peru.

Simple, passionate, efficient: a solid global implementation of one of the cheapest irrevocable life-improvements (fixing cleft palates) modern medicine can offer. Smile Train is a remarkable charity.

They are fascinating on a few levels, from the clarity of their work and tactical training local doctors, their selection of spokespeople and Oscar-winning short documentary, to the controversy of their fundraising tactics, and the lingering drama of an early fork. If you haven’t heard of them before it’s worth taking ten minutes to find out what they do.

A comment from Cursor’s Richard Nash, who is working on Red Lemonade, a site for group review of publishing submissions with heatmap-style annotation (rather than having publishers manage the review process). He gave a great talk about why authors should review one another’s work, and why we already live in a world where we all manage the meaningful review processes.

Rice University losing its wallet or its mind?
Tuesday September 14th 2010, 4:04 am
Filed under: chain-gang,fly-by-wire,Not so popular

The Rice University administration seems to be having a very bad summer. A few weeks ago, they secretly planned the sale of KTRU, their nationally-renowned independent campus radio station. They ‘managed to keep their ongoing negotiations completely quiet until about 12 hours before the sale was approved by Houston’s Board of Trustees’. I didn’t realize until today that the sale was considered final — students have been protesting since it became public, and the administration has offered no explanation.

Now last week they leaked the news hinting they would shutting down their promising digital Rice University Press contradicting the will of RUP’s Board of Directors. This, after commissioning an external review that recommended supporting it and integrating it better into the Library and related services — and again, with no public explanation.

I have fond memories of Rice University — I studied there during high school; they supported Connexions in its infancy; friends of mine teach there. (I try not to hold the whole Sidis incident against them.) So it pains me deeply to see this wanton self-destruction. I can’t imagine what they stand to gain from either move — they will lose any money from the sale to discontented KTRU alumni from the radio’s 40-year history. (No one seems willing to support that sale — here is a petition from 350 concerned UH alumni in support of keeping the radio station at Rice.) What gives?

New photos York style, and mesh completionism
Wednesday September 01st 2010, 1:40 am
Filed under: chain-gang,indescribable,metrics,Not so popular,SJ

While still recovering from a Rein’s Deli hangover, I found myself the subject of the Ragesoss lens last weekend.   Good energy, well captured.

@Ragesoss: It is a mathematical notion applied to ideas. A conceptual space around a theme is full of different concepts, each related to the theme in some way. Such a space can be described in terms of facets that can be used to describe a concept: for instance, you might describe ideas for laying out a garden in terms of their complexity, suitable climate, or total size… or many others. Complexity and size are sometimes linked. You can imagine the conceptual span of a set of facets, or their dependency on one another, as corrolaries of the span and independence of vectors being used as the basis for an abstract space.

A mesh is a limited set of elements that can be used to effectively describe an infinite space of ideas.  Human languages are full of concept meshes.  The easiest to discuss are one-dimensional meshes (ideas that span the spectrum of a single facet):

  • color words – the spectrum of visible colors is split into a set of common colors.  this set of names is a casual mesh for the visible color spectrum. (casual in that there is no explicit metric used to determine whether all parts of the visible spectrum are ‘equally’ represented by words)
  • shape words – shapes may be described as circular or oval, square or rectangular.  There is a humorous ‘proof’ that the only skew triangle has angles (45, 60, 75) – that all others are roughly equilateral, isoceles, or right.

Higher-dimensional meshes include texture words (smooth, rough, bumpy, prickly, soft, firm, sticky… – covering facets of friction, give, tangible local structure, and more).  Most higher-dimensional meshes in language are incomplete (we rarely form words for concepts whose realizations are not in common use).

If you define a metric for the distance between two points on a spectrum, you can construct an “equally-spaced” subdivision of the space, or a balanced mesh.  This splits a space into a set of characteristic elements (here, concepts) or nodes which can be used to describe anything elsewhere in the space.

Choosing a metric is important and difficult.   For instance, once we found a way to measure color by the wavelength of its light, we could ask for enough common color words such that every frequency of visible light is no more than 50nm from the wavelength of one of the characteristic colors.  In practice, humans see different parts of the color spectrum with differing degrees of sensitivity, and we become familiar with certain constant colors in our environment .  So while the rendered spectrum does not devote much space to Yellow or Orange (in contrast with green and red), we have many more characteristic words for yellows and blues than a straight “wavelength subdivision” would suggest.

It is also difficult to define facets that are independent of one another; but this is not necessary.  It is mainly important for each facet to be easy to observe and agree on.

For a given metric, you can describe the fineness of a mesh in terms of the maximum distance from any concept to the closest characteristic element.  (or sometimes twice that distance – as a description of the “largest” concept that could “slip through” the mesh without including any of the characteristic elements.)  If you have different metrics for each facet, a synthetic combined metric must be created that is consistent with each.

A balanced mesh is then one in which the fineness of the mesh is essentially the same for all subsets of the conceptual space — so, a set of color words that provides equal facility in describing perceived colors at all points on the color spectrum.   (Again, a suitable metric here might be one that stretches out the spectrum in regions perceived very well by the human eye, or colors that come up frequently in human life — the latter a metric that changes with social context.)

One can often have a clear definition of a mesh without having words for some of its characteristic elements.   This happens often with a multifaceted space, where the intersection of well-known values of each facet is an unknown combination that has no word to describe it.   One common way of constructing a balanced mesh involves creating a balanced mesh for each facet, and then defining a concept for every combination of those single-facet ideas.  Building a “complete” set of characteristic concepts can be thought of as mesh completion.  It is a way of thoroughly grokking a space of related concepts.  And the fineness of the resulting mesh is a measure of how effectively one has used language, imagery, or other methods to illustrate the limitless variety possible within the constraints of that conceptual space.

Filed under: chain-gang,international,Uncategorized,wikipedia

Drumbeat is a new Mozilla umbrella project, consolidating its efforts to support and enhance the open web — the free and transparent elements of the Web that we love and rely on.   It combines earlier work on One Web Day, educational outreach, and direct grants to developers improving the free tools needed to expand the web.

The first global Drumbeat Festival will be held in Barcelona on November 3-5, and creators everywhere are invited.   I have been part of local Drumbeat events in New England this summer (run by Ben and Dharmishta), where the pervasive interest in learning was wonderful and fascinating.   I can’t wait to see a larger festival come together.

This year’s theme is Learning, Freedom and the Web. The open nature of the internet is revolutionizing how we learn, and Drumbeat welcomes teachers, learners and technologists from around the world who are at the heart of this revolution.

Join us in Barcelona for three days of making, teaching, hacking, inventing and shaping the future of education and the web.

Drumbeat Festival 2010: Barcelona Nov 3-5

Drumbeat Festival 2010: Barcelona Nov 3-5

Who will be there?

The festival is designed for makers, writers, hackers — on creation more than discussion.   There are currently over 100 confirmed participants, including:

Mitchell Baker, Mozilla’s Chief Lizard Wrangler
Manuel Castells, Open University of Catalonia
Joi Ito, Creative Commons
Anya Kamenetz, author, DIY U
Gever Tulley, Tinkering School
Mary Lou Forward, OpenCourseWare Consortium
Brian Behlendorf, Apache Foundation
Connie Yowell, MacArthur Foundation
Johannes Grenzfurthner, monochrom / metalab

A Festival!  Should I bring my best hat?

Hat, HUD, musical instrument… Drumbeat is not your typical conference festival.  Imagine a folk festival combined with a teach-in with a dash of outstanding oratory for good measure. That’s the plan.

You’ll have a chance to propose and invent activities throughout the festival. You can read a small sample of planned activities to get your creative essences flowing.

How do I sign up?

Registration opens on August 25.  You will also be able to apply for a travel scholarship, propose activities, or offer to volunteer.  If you are not already on our email list, you can sign up now.  Reminders will be sent out when registration opens.

Meanwhile, please spread the word – encourage your friends and colleagues to sign up for announcements, start discussing what you’d like to invent or create while there and what you might show off!



Drinking the Kool-Aid (sic)

Filed under: %a la mod,chain-gang,poetic justice,Too weird for fiction,Uncategorized,wikipedia

Don’t Drink the Kool-Aid, they say — commonly remembered as a reference to the final drinks of most victims of the Jonestown massacre. At the time the phrase was coined,Tom Wolfe’s book The Electric Kool-Aid Acid Test was also popular, and in the context of  60s hippie culture, “drinking the kool-aid” could also mean taking LSD.

Early reports about the compound referred to “cool aid(sic) packets”.  Since then, Kraft Foods and others have maintained that it was an urban legend that they all drank Kool-Aid, and that it was Flavor Aid instead – a misunderstanding thanks to the genericization of “cool aid” as a term.

Enter YouTube, Wikipedia, and the open web.  After decades of casual debate, we can now resolve half of the mystery: they certainly had both powdered drinks at Jonestown, and we have a handy link to the 9 seconds of a newsreel that shows it first-hand.  Whether the final drink was from one set of packets or the other, this handily settles the question of whether they had Kool Aid on site.  It’s the first time I’ve seen a few seconds of video effectively used as a moving-image citation!  Note to Readers: you can also embed YouTube videos and tell them where to start playback.

Hat-tip to brassratgirl for helping me towards enlightenment on the issue.
