Finding my bliss

April 12, 2015 by Steven D. Brewer

I saw an article this morning about finding your bliss derived mostly from an interview with Joseph Campbell. I realize how fortunate I am to have as much freedom as I do to choose projects to work on that I think are worth doing. But I can tell when I'm working too much when, looking back, I see that it was a whole week since I wrote a haiku.

It's been a month of keeping plates spinning, one after another after another. My class is working on their final projects: amazing netlogo models! I almost have Junior Writing through the quinquennial review: just one more question to answer. We've got the beginnings of a draft for IT strategic planning: four goals defined and assignments to draft the narrative. I'm feeling like the Amherst Media board is finally starting to pull together: committees have projects and are moving forward. Makers at Amherst Media is hanging in there: the drop-in sessions are picking up steam. Hack for Western Mass is moving forward: full speed ahead! So I took Saturday to just decompress.

It's been a perfect day. I got up early. I had Love Crunch granola with fresh raspberries and coffee for breakfast. Lucy, Charlie, and I solved the Jumble. I went back to bed for an hour. Lucy and I drove downtown to walk around and play Ingress. We went to the Library (where I got Karen Memory!) We went to the grocery store. I came home and fixed chili. While it was simmering I took a bike ride with Daniel. We got back just in time for me to watch the Red Sox while I ate chili and had a beer. I napped for a bit while the game was on. Then I went out to play a bit more Ingress then stopped at Raos for a latte to compute and write haiku. I got home just in time to have taco bowls which Daniel had made for dinner. Afterward, we watched some Tony Tony Chopper. And now it's time for bed.

I particularly want to write more haiku over the next few weeks as I work to pull together my next book of haiku. I've decided on a theme and have hatched a plan to develop the imagery. I have enough haiku now, but it would be good to have a few more to let me drop some of the weakest ones. Hopefully, I'll have the new book ready to take with me to the UK.

I still have some questions: Do I want to keep to the same format? Or mix it up? Should I stick with the bilingual pattern? Or go monolingual? It's fun to think about the possibilities.

Online Threats and Phishing

April 7, 2015 by Steven D. Brewer

Recently, I was invited to co-present on security. We each brainstormed up a list of what we thought were the biggest online threats today and some practical steps people can take to protect themselves. Here is the list I created:

Brewer's top five threats

  1. Dangerous scripts (flash, javascript, others) in browser
  2. Insecure/questionable links (in email, in social media, etc)
  3. Insecure attachments
  4. Insecure plugins, extensions, apps, etc
  5. Social Engineering

Brewer's recommendations

These are intended to be some basic steps anyone can take to improve their security, although they are not necessarily convenient.

Use Firefox with both no-script and flashblock enabled.

Only do banking, human-resources stuff, etc with fresh web-browser session:

  • Use a different browser only for that purpose
  • Start up browser, do session, quit browser
  • Do the same for insecure/questionable links.

View (and send) email as plain text only

  • Look at links carefully
  • Don't leak information via images and web-bugs

Look at full headers of questionable email

  • Only trust headers written by known hosts.
  • Learn to recognize suspicious hostnames.

Don't just click on links!

  • know the structure of links:
scheme://[user:password@]hostname:port/path?query_string#fragment_id
  • Navigate there directly
  • Critically evaluate links
  • Look at hostnames & paths
  • Avoid apps that obfuscate links
  • Use copy & paste
  • Use "whois" for questionable hostnames
  • Remove parts of path that might have tracking information

Don't be a monoculture -- don't just use the most widespread software:

  • Open Microsoft documents with Libre Office.
  • Don't use Acrobat: Use Preview (or something else).

Only use software that has a strong, open community

Periodically review addons/extensions/apps for browser, phone, social-media apps

Question/verify the provenance of people & information

  • Confirm human references "out of band"
  • online resources — even DNS — can be spoofed
  • fake hostnames can look like real ones

Ne IKUmos en Lille

April 2, 2015 by Steven D. Brewer

Jen mia propono kiun oni neis por IKU-prelego ĉe la Universala Kongreso.

La Mondo Ne Estas Kiel Ĝi Ŝajnas: Historio kaj estonteco de mondaj altern-/pliigit-realaj interretaj ludoj

RESUMO

La Interreto dum la pasintaj 20-jaroj ebligas novan artan/kulturan produktaĵon: la amase retan ludon. Tiaj ĉi ludoj, iam la fako nur de fanatikuloj, nun estas grandskala, tutmonda, kultura fenomeno. La plej gravaj ludoj postulas la saman kapitalon de granda Holivuda filmo. En tiaj ludoj, homoj tutmonde povas partopreni kaj interagi por konkursi, kunlabori, kaj amuziĝi. Multaj el ĉi tiuj ludoj okazas nur en komputila universo sed iom post iom ekaperas ekzempleroj en kiu oni ne nur ludas en komputilo sed ankaŭ en alterna aŭ pliigita realo kiu kunekzistas kun la vera mondo. En tiu ĉi proponita IKU prelego, mi skizos la historion de altern-/pliigit-realaj interetaj ludoj; pli detale montros du ludojn; priskribos la rilaton inter lingvo, arto, kaj kulturo de ĉi tiuj ludoj; priparolos kiel ĉi tiaj ludoj jam ekinfluas la ceteran kulturon (ekz la "ludigado" de klerigado kaj merkatiko); kaj proponos, finfine, ke oni konsideru Esperanton kiel sukcesan mondan altern-/pliigit-realan ludon.

ENKONDUKO

La Interreto dum la pasintaj 20-jaroj ebligas novan artan/kulturan produktaĵon: la amase retan ludon. Tiaj ĉi ludoj, iam la fako nur de fanatikuloj, nun estas grandskala, tutmonda, kultura fenomeno. La plej gravaj ludoj postulas la saman kapitalon de granda Holivuda filmo. En tiaj ludoj, homoj tutmonde povas partopreni kaj interagi por konkursi, kunlabori, kaj amuziĝi. Multaj el ĉi tiuj ludoj okazas nur en komputila universo sed iom post iom ekaperas ekzempleroj en kiu oni ne nur ludas en komputilo sed ankaŭ en alterna aŭ pliigita realo kiu kunekzistas kun la vera mondo.

Ekde la plej fruaj tagoj de la interreto, oni multe uzas ludojn por esplori la kapablojn kaj nuancojn de reta interago. Eble la plej frua altern-reala reta ludo estis LambdaMOO (CURTIS, 1990) kiu similis al pli fruaj tekstaj aventuraj ludoj, ekz Colossal Cave Adventure (CROWTHER, 1976; CROWTHER & WOODS, 1977) kaj la sekvaj Mult-Uzantaj Galerioj (TRUBSHAW, 1978; BARTLE & TRUBSHAW, 1980), sed malsamis en tiu ke la ludistoj povis ne nur esplori, sed ankaŭ kunkrei la medion kaj interparoli (tajpe) kun homoj en la samaj "lokoj" en la ludo. LambdaMOO estis virtuala versio de la domo de la kreinto. La komunumo bonvenigis samsekamajn kaj transgenrajn homojn (oni taŭge komenciĝas en la ludo/mondo en ŝranko) kaj donis al ili sekuran lokon por provi aliajn modojn de esprimo pri identeco kaj genro.

Sekvaj ludoj enkondukis la ideon ke per la reto multege da homoj povus samtempe partopreni: Masive Multiludantaj Rete Rolludoj (t.e. Massive Multiplayer Online Role-playing Games (MMPORG)) kiel Ultima Online, Everquest, kaj la plej konata World of Warcraft. Pro la eblo atingis grandegan partoprenaron, ludoj transiris el la fako de nur retaj teĥnikuloj kaj fariĝis varo de grandaj firmaoj. Nun, StarCraft 2 kaj Dota 2, estas mondskale konataj ludoj kiuj allogas grandan intereson. Firmaoj elspezos dekojn da milionoj da dolaroj por produkti unu novan ludon kaj konkurencoj fariĝas internaciaj spektakloj. La internacia Dota 2 konkurenco en 2014, “The International”, oftertis ĝis $10,9 milionan da prezoj kaj oni montris la ludojn per internacia televida reto ESPN kun samtempa komentado.

En 2008, Jane MCGONIGAL organizis mondan altern-realan ludon Lost Ring (La Perdita Ringo) kiu ricevis subvencion de mondaj firmaoj kaj organizaĵoj, precipe McDonalds kaj la Monda Olimpika Komitato. En la ludo, aktoroj ŝajnigis esti atletoj kiuj troviĝis, sed ajnaj memoroj kaj kun tatuoj kiuj diris “Trovu la ringon perditan” (en Esperanto!) Tiu ĉi ludo fariĝis speciale interesa por samideanoj ĉar oni uzis Esperanton kiel enigmon en la ludo. Mi mallonge resumos la ludon en la prelego kaj montros ĝiajn ecojn.

En 2012, la firmao Google starigis la ludon Ingress, pliigit-reala ludo kiun oni faras per poŝtelefono. Ĝi bone montras la ecojn de aktuala pliigit-reala ludo. En la ludo, ekzistas portaloj per kiu eniras la mondon “ekzotika materio”. Por ludi, oni devas viziti en la vera mondo la lokojn kie situas tiuj portaloj, ofte ĉe publikaj konstruaĵoj kaj artaĵoj. Praktike, oni tiel devas multe promeni de loko al loko por partopreni kaj unu el la kromceloj de la ludo estas plibonigi la san-staton de la partoprenantoj. En la prelego, mi priskribos kaj montros la ludon.

En la lasta sciencfikcia literaturo, verkistoj ekimagas kiel ĉi tiaj ludoj fariĝos parto de la ĉiutaga kulturo. En la fruaj 2000-aj jaroj, verkistoj komencis priskribi kiel tiaj ludoj povas transiri inter la alterna, luda realo kaj la vera realo. En la libroj Pattern Recognition (GIBSON, 2003), Halting State (STROSS, 2007), Little Brother (DOCTOROW, 2008), kaj This Is Not A Game (WILLIAMS, 2009) aŭtoroj priskribis kaj ellaboris la ideon ke tiaj ludoj ebligos la interrilaton kaj kunlaboron de homoj ĉirkaŭ la mondo. Mi resumos la ecojn kiujn oni priskribis kaj montros kiel la estonta mondo kiun oni priskribis jam multflanke efektiviĝas.

Ludoj ekhavas kreskantan influon sur la cetera kulturo kaj bonan kaj malbonan. La komputilo fariĝas pli ol nur “ilo” sed vera parto de la korpo kaj cerbo kaj menso (TURKLE, 1984; TURKLE, 2011). Lastatempe, oni multe priparolas kiel “ludigi” diversajn ecojn de la ĉiutaga vivo, precipe instruadon kaj merkatikon. Ofte la planoj kaj proponoj montras danĝeran nescion pri la lecionoj kiujn oni lernis pri kondutismo antaŭ jardekoj. Ankaŭ estas danĝero pri la datenoj kiujn oni devas dividi per ajna Interreta agado, sed precipe per poŝtelefonoj. Ludojn kiel Ingress postulas ke vi dividu kun Google kaj la poŝtelefon-firmaoj (kaj registaroj) kie vi estas kaj kien vi iras.

Esperanton mem oni povas pripensi kiel altern-/pliigit-realan ludon. Malmultaj homoj partoprenas Esperanton kiel parton de la profesia vivo, sed samtempe dediĉas multe da tempo al ĝi: por lerni, instrui, organizi, renkontiĝi, diskuti, kaj konstrui literaturon en kaj pri mondo kiu similas, sed ne tute kongruas, kun la ĉiutaga mondo. Mi esploros kiel per lenso de altern-/pliigit-realaj ludoj ni povas kompreni kaj eble plibonigi Esperantujon.

Faculty Survey

March 15, 2015 by Steven D. Brewer

The College of Natural Science is conducting a survey of the faculty. It was somewhat interesting to look at the questions and to gauge my own reactions to them. The survey focused primarily on the relationships between the faculty member and the department -- and the college. And then dealt with effort spent on research, teaching, and service.

Beyond answering the questions, I pointed out the two things that I've been raising with the University for the past 10 years. First, that the survey itself demonstrated the ambivalent relationship the University has with non-tenure-system faculty: the list of faculty ranks did not even include my rank "Senior Lecturer II" (among the 10 or 15 that were there) -- I just had to pick "full-time lecturer". Many faculty would argue that becoming a lecturer is having failed -- and this attitude pervades a whole range of micro-aggressions that the administration practices upon non-tenure-system faculty. The most important of these is the lack of support for on-going professional development. While tenure-system faculty get a sabbatical every seven years, non-tenure-system get a sabbatical, well, never. And the institutional support for non-tenure-system faculty to attend conferences or training is practically non-existent. This perhaps made sense when non-tenure-system faculty were purely short-term appointments, but when they work for 15 or 20 years in the same position, it would benefit the institution to make a strong commitment to helping these faculty stay current and retrain.

I pointed out one other thing too. The survey discussed the relationship with the department and college (and, to a lesser extent, the University as a whole), but it did not mention the faculty union as a source of community. The union has been really important to me in terms of getting to know colleagues from across the institution and thinking about scholarship from a broader perspective. And for making really tremendous gains over 10 years to improve the circumstances for non-tenure-system faculty. Go UMassMSP!

Pictures Don't Lie

March 10, 2015 by Steven D. Brewer

I've always taken lots of pictures in St. Croix. Pictures don't lie, but they don't tell the whole truth either. You can see the flower, but can't smell it -- nor hear the bees buzzing. You can't feel their rubbery goodness. You can't see how they wave in the breeze — nor hear the ocean waves on the beach below. You can't see how they seem to change color when a cloud passes over the sun. You can't see how the flowers appear like magic overnight, but have already fallen off by midafternoon. You can't see how some flowers are only here for a short season, while others bloom year round. The pictures offer a truth, but they're not the truth.

Last full day

March 10, 2015 by Steven D. Brewer

Today is my last full day on island. The time has passed quickly. We've been busy launching the trapping program (getting traps out of storage, getting access to the refuge, putting the traps into service, etc). We also had to move to a different cottage, which was surprisingly disruptive: afterwards you can't find anything.

I don't usually plan to come down for such a short stay, but this was a special occasion. And today we celebrate that occasion: Buzz's 60th birthday. Buzz is expecting around 20 people. The plans are all laid: we've arranged for the food from Rose's and will pick up the drink this afternoon. We couldn't get beer from the Fort Christian Brewpub -- they didn't have any IPA ready. But we can get some Island Hoppin' IPA in the bottle, which is pretty good. And maybe a bottle or two of rum as well.

We've had good success in the field. We've had nearly 50% trap success: a mix of recaptures and new animals. We had one rather harrowing experience with an Africanized bee colony in a tree hollow that became disturbed and wouldn't let us get to one trap site. So, after the colony calmed down, we moved that trap to a different site. Buzz only got one sting, but it's amazing how terrifying it is to have bees swarming around you, buzzing, and bumping into your head.

Yesterday we visited Christiansted to visit the boutiques and watch the crab races. I mostly walked around and played Ingress. We took three hermit crabs and entered them, but didn't have any win. But it was fun. The view from the boardwalk is amazing.

With Venus to guide us, we walked back to the car in the lot with the Baobab tree and drove back to Cottages.

On island

March 6, 2015 by Steven D. Brewer

Buzz, Jonathan and I arrived "on island" yesterday afternoon. We made a quick stop at the store to get a few supplies (beer and breakfast, mostly) before checking in at Cottages. Then we had dinner at Lost Dog -- our usual first stop when we get here.

Today, Buzz had ambitious plans. He wanted to put some data loggers into the salt pond. We borrowed a kayak and, after getting stuck once, he headed off across the salt pond.

It turns out the pond is only about two feet deep. He gets to slog back tomorrow to collect his data loggers.

We met a new friend at the refuge who helped us collect our traps and other stuff and get a key to the gate so we could set some traps. We put out 15 traps and should have some animals to work with tomorrow.

One new toy is a thermal camera. I saw one at Home Depot and sent a picture to Buzz who ordered one instantly to be delivered directly here: It arrived today and we've been playing with it since. The last time I had checked, thermal cameras still cost in the $1000s. But they're down to ~$250 now.

Buzz has more friends arriving tonight in advance of his birthday party on Tuesday. Everyone who's anyone will be there. With catering by Rose's Dream Cuisine and beer by the Fort Christian Brewpub it will be a night to remember.

Maker Technologies and the Internet of Things

March 3, 2015 by Steven D. Brewer

Once upon a time, I was nearly laughed out of the room for suggesting that, someday in the distant future, everyone would have their own computer. Now, of course, you probably have several computers. But you actually have a lot more computers than you think.

Some of your computers are in obvious places, like your laptop or cell phone or game system. But others are invisible to you: In your car. (Your car probably has multiple computers in it already!) In your microwave. In your television.In your refrigerator. In your thermostat. Did you know there is probably a tiny computer inside your microSD card? (It's a modified ARM processor that maps out bad memory location and remaps the file-system so the FLASH memory gets exercised evenly).

Soon, there will be computers inside everything. Imagine your disposable soda cup at the restaurant with a video advertisement playing on the cup! Or food packaging that turns black (or green or yellow) when it's expired. But the next really big step will be that these computers won't just be standalone computers: they'll be networked and able to talk to one another. Welcome to the Internet of Things.

We're offering a class about Maker Technologies and the Internet of Things because, although the future is not quite here yet, you can already start exploring this new world. And begin developing the basic skills that will allow you to start using these technologies immediately.

Some of the skills are basic: Navigating the Linux operating system using the bash shell and a text editor; Applying fundamentals of computer communication and Internet Protocol networking; Programming with Python. Others are more specialized: Collecting and transforming data from sensors using a GPIO; Controlling electronic devices; Building and using client-server applications.

Finally, there's a dark underside to being surrounded by all of these computers: Who really controls them? Are they collecting data about you? Who can see that data? It's imperative to think through the security implications of these systems to prevent intrusions and mitigate their effects when compromised.

The course is being offered by Steven D. Brewer, Director of the Biology Computer Resource Center, and Christine Olson, a doctoral student in the Department of Communication at UMass. They are co-founders of Makers at Amherst Media, a local group focused on building community and making technology accessible to the public.

Former UMass student and entrepreneur Wayne Chang, talking about technology startups recently, identified the Internet of Things as the "next big thing". We agree — and hope you'll join us this summer for Maker Technologies and the Internet of Things July 12 through 25.

Tour of UMass Center at Springfield

February 25, 2015 by Steven D. Brewer

On Tuesday, Feb 24, I visited the UMass Center at Springfield and was given a tour by William Dávila, the Director of Operations. We discussed the needs of Hack for Western Mass and walked through the facility looking at relevant spaces. The space is modern with reconfigurable furniture. It appears to me that the facility offers a good match for our needs.

Here is the detail from a map (click to open the full version in a separate tab) that shows the relevant section of the facility. (Most of what is clipped off is the part of the facility dedicated to the Nursing program which has specialized facilities not really relevant to our purposes. Really cool to visit, tho!)

There is a large Learning Commons/UMCS-Lounge area that would work well for a Friday Night reception, as a common area to put snacks and food, and for people to congregate informally during the day.

There is a large plenary space (rm 14) that, with tables removed and additional chairs, can seat up to 170. Note that all of the rooms have cameras and videoconferencing equipment, so we could have overflow into other rooms if we needed more space.


There is a hallway of classrooms (rooms 2, 3, 4, and 5) that each would work well for 1, 2, or even 3 groups to work in (excepting possible room 2, which is a bit smaller). By staying in this hallway, we could keep all of the groups together and adjacent.

There are a number of additional rooms that could be available for other purposes. There is a computer lab (room 1) that could possibly be used for the Kids Hackathon. There are two fancy conference rooms and a number of smaller breakout rooms, but they're mostly not ideal for our purposes. If we need a place to store materials in advance of, or during the Hackathon, a breakout room or rooms could be made available.

It sounds as though we may have the facility largely to ourselves although we should try to make the arrangements promptly to ensure we lock in the date. There will need to be a commitment to pay for staffing for hours when the facility would not normally be open, which includes both Friday evening (ie, after 5pm) and Sunday. These costs would be simple cost-recovery for a single person to open the facility. For the Friday evening ice-breaker, another possibility might be to use the Federal Building at 1550 Main (see below) which has a large lobby that could be used for a reception and is just across the street. But the Lounge seems preferable to me, so people can see the space where we'll be working.

There is wifi provided by Eduroam and they have a guest account provisioned which can be used by anyone who doesn't already have Eduroam credentials. There is an attached parking garage for Tower Square and we can get parking permits that reduce the daily charge to $5. (We might consider whether we can find a way to sponsor parking so participants don't have to pay).

One piece of good news: We are not required to use a particular catering service, although Hot Table (just below) and Nadim's (down the street) are convenient and have been helpful.

The staff were eager to have us bring the Hackathon to Springfield and were excited about the possibility of helping to cross-brand and publicize the event.

Building effective user communities

February 17, 2015 by Steven D. Brewer

In 2013, I wrote about building digital signage with Raspberry Pis. We're still at it. Several months ago, I pointed out one of our displays to our CIO and mentioned that there didn't seem to be any forum to sharing information about solutions on campus. She mentioned she was aware of 12 independent efforts on campus trying to buy, build, or implement digital signage, none of which are aware of the others. She's taken the issue seriously and is moving the campus toward building user communities around important topics. Toward that end, they've scheduled an event for Thursday at 1pm.

The current model that the campus has fostered, are "Tech Talks". But they are organized around a few-to-many model. I think user communities need to be less structured. Our UMass Drupal Users Group could serve as a good model. The qualities that have made the group so successful include: a dedicated core group of users that draws from both on and off campus, an online forum to post announcements and schedule events, simple threaded discussion, and regular meetings with both structured and unstructured events.

The biggest challenge to making user communities successful is getting administrators at the University to value the time commitment necessary on the part of faculty, staff, and students to participate and make them work. It takes time to build relationships and the social capital necessary for trust and engagement. But over time, I think it could transform how the campus operates.

Montetoj kaj valoj de loka agado

February 7, 2015 by Steven D. Brewer

Je la 19a de julio, 2003, mi registris la domajn-nomon amherstesperanto.org. Mi starigis retpaĝaron por anonci lokan Esperanto-grupon kaj komencis kunveni ĉiusemajne en loka restoracio: la glacikremejo Bart's.

Kiam mi estis doktora studento en Kalamazuo, nelonge post mi esperantiĝis, mi partoprenis lokan grupon tie kiun organizis Ĝan Starling. Tiu grupo multe influis mian pensadon pri Esperanto kaj la komunumo kiun ĝi povas flegi. Mi renkontis multajn samideanojn tiel kaj havis multajn interesajn konversaciojn. Kaj, kompreneble, multe plibonigis mian regon de la lingvo. La grupo estis ankaŭ la kerno de diversaj aliaj agadoj: vojaĝoj al aliaj kongresoj kaj la organizado de lokaj kongresoj.

Post kiam mi doktoriĝis, mi translokiĝis al Masaĉuseco, kaj tuj serĉis tian lokan grupon, sed ne trovis. Mi kontaktis la lokajn s-anojn kiujn mi trovis en la membraro de E-USA kaj aranĝis kunsidon por diskuti. Sed ili malmulte interesiĝis pri semajnaj kunvenoj. Mi estis tro okupita pri mia nova posteno por organizi ion tuj, sed atendis.

Post kelkaj jaroj, mi havis iom pli da tempo kaj starigis retpaĝon por reklami la grupon. Fakte, en tiu momento, tute ne ekzistis "grupo" -- mi simple anoncis ke "la grupo" kunvenos semajne. Kaj ekde tiu momento, mi iris al tiu loko semajne por "kunveni". Dum kelkaj semajnoj, neniu venis. Sed, iutage, ulo alvenis mian tablon kaj alparolis min Esperante! Li estis universitata studento kiu eklernis Esperanton antaŭ kelkaj monatoj kaj volis babili. Iom post iom li diplomiĝis kaj translokiĝis alstaten. Sed alvenis aliaj kaj la grupo ankoraŭ ekzistas.

Lastatempe, mi ne plu havas tempon por multe organizi, sed ni daŭre kunvenas -- ne ĉiusemajne, bedaŭrinde. Sed ĉisemajne, alvenis nova komencanto kiu jam sufiĉe bone parolas! Li ne multe parolas, sed li ŝajne komprenas sufiĉe.

La grupo havas siajn montetojn kaj valojn: foje oni aktivas kaj kunvenas kaj diskutas ofte. Foje, ĉiuj estas tro okupitaj kaj la grupo dormetas. Sed ĝi daŭriĝas kaj valorigas la laboron.

La loka grupo por mi estas la plej grava kialo mi daŭre interesiĝas pri Esperanto. Mi tre ŝatas la sperton paroli en alia lingvo: la menso streĉiĝas kaj oni sentas sin parto de speciala socio. Kaj la Esperantistoj estas plej ofte tiel interesaj homoj. Kia rara plezuro!

Board Retreat

February 1, 2015 by Steven D. Brewer

Last year, as a new board member at Amherst Media, I found it very useful to have a retreat. At board meetings, we're generally focused on the business of the organization. It was really valuable to spend a few hours reflecting on the role of the board and the strategic needs of the organization. As the new president, I thought it was worth organizing a retreat this year as well.

We met at Willits-Hallowell in South Hadley. It was a lovely drive over the Notch, in spite of the frigid temperatures. I was pleased that we had nearly full attendance. We had a full agenda and we mostly kept to our times.

I began the meeting by welcoming everyone, thanking them for their attendance, and inviting everyone to introduce themselves. We have a wonderfully diverse and talented board.

In thinking about the retreat, I found a checklist that I thought might be useful to structure our thinking as we move forward. We went through the items and had some good, focusing discussion about some strengths of our board and other places that could use some attention. I was pleased that most of the items identified aligned extremely well with the agenda that we'd set for the day.

We spent some time reflecting on our mission and the current activity of the organization. We discussed the challenges of our building plans; we reviewed our strategic shift from trying to launch a capital campaign to annual fundraising; and we assessed the results of our first direct-mail solicitation. It was an extremely informative overview of where the organization is and where it's going.

In the afternoon, we heard from Martin Miller the CEO of WFCR (or New England Public Radio, as they're re-branding themselves). He spoke to us primarily about their successful 50th anniversary capital campaign which has enabled them to move into newly renovated space in Springfield. Although many people think public radio and television are supported by the government, in fact less than 10% of their funding comes that way. The largest amount (around 40%) comes from the on-air fundraising and is mostly small monthly donations. For their capital campaign, they had many years of fundraising data and their connections with NPR provided opportunities to reach well-known people to lead efforts or offer benefits. One of their biggest challenges was due to their uncertain early efforts to get a new building, which resulted in confusing messaging and some "donor fatigue" as their first efforts to secure a new building hadn't succeeded. It was a frank and very insightful look at a successful non-profit which was both encouraging but also somewhat sobering in terms of how far we have to go.

We wrapped up by collecting some "action steps" for things we want to do. There were several simple suggestions for things to do to improve our communication and organization: creating a calendar for committee and subcommittee meetings, having a bit of unstructured time for socialization before meetings, and having scheduled meetings for the executive committee to set the agenda before board meetings. We are already the process of reviewing and amending the bylaws. I'm hoping we can restructure the board subcommittees to align better with a road map for future activity, build better publicity, and help us grow our engaged membership.

I left the meeting feeling that we'd learned a lot and rededicated ourselves to the tasks at hand. It was time well spent.

Teaching with Netlogo

February 1, 2015 by Steven D. Brewer

Originally, I was not scheduled to teach in the spring, but during scheduling it became clear that there was a large unmet need and was... persuaded to open a section of the writing class. For my theme this semester, I'm asking the students to explore agent-based modelling with Netlogo. I've wanted to get back to working with Netlogo and in the fall a faculty member at WPI contacted me about working with her on Netlogo. I've reconnected a bit with the community, updated and posted my models at the Modeling Commons.

My goal for their final projects is for them to identify something in the literature for which no agent-based model exists in Netlogo and to create the model and write a report about it. Some of the students are anxious about the programming, but I think it will be very doable and have laid out a series of steps to get them up-to-speed.

For the first class meeting, I had the students observe a live ant in a petri dish to write about it and then look at the Basic Ant model I constructed. In the model, the ant moves forward until it encounters the "dish", backs up, turns 20 degrees, and moves forward again. I asked the students to suggest how actual ant behavior differed from the model. One student pointed out that the model always turned in one direction while the ant sometimes turned either way. I then pointed them at a publication that shows that ants have a left-ward turning bias and we elaborated the model with a bit more logic.

For the Methods Project, I'm asking them create a multi-panel scientific figure that shows a biological pattern generated using an existing Netlogo model coupled with a photograph that shows the same pattern in real life. We talked about some of the resources available on campus (the greenhouses and collections) and I'm looking forward to seeing what they come up with. It's always one of my favorite projects.

Last semester, I experimented with trying to work with larger student groups. I've generally avoided groups larger than three, but several faculty in the department routinely have students work in groups of 5 or more. Since I only had 5 Galileo computers, I decided to try groups of up-to 5. I would call the experiment a failure and consistent with my previous experiences. As groups grow beyond three it becomes much more likely that someone in the group can't find any meaningful way to contribute to the project.

This semester, I'm debating whether to have students work in groups at all. Or maybe work in pairs. I still have a few weeks before I have to make up my mind.

Semester Launched

February 1, 2015 by Steven D. Brewer

The semester has launched. The past couple of weeks have been the typical flurry of activity. Over the intersession, we made a bunch of upgrades. I missed a lot of the action by visiting Phil during the first week of January, but came back just in time to be totally swamped.

We installed SSDs and RAM in the intro lab computers and updated them to Mavericks. It makes a huge difference in the performance of the computers, especially for logging in and launching applications. I'm hopeful we can do the ISB computers next.

We also decommissioned the first of our old Solaris servers. Over the next year, we will finally put them all to bed. I started using SunOS, and then Solaris, while I was still a graduate student. It was never my favorite flavor of Unix, but when I started using it, it was a standard that most packages supported well. For the past five years, it's been, well, a nightmare trying to support anything.

Finally, I reorganized the arrangement of tables in the BCRC. I had originally proposed two different arrangements, but when they originally installed the tables, they hadn't included appropriate hardware to gang the tables together both ways, so I had laid it out in circles and waited until we could fix it. They finally installed the hardware at the end of the semester and over the break, I made the change. So far, the results are extremely encouraging. The circles were good, but this is even better -- especially for teaching: it enables you to make eye contact more easily with the students while presenting. And even students working alone suggest that it "feels" like you have more space to spread out.

Visits to Champaign-Urbana Makerspaces

January 9, 2015 by Steven D. Brewer

I've been spending a lot of time working on Makers at Amherst Media. We shot a new show discussing the afterschool program and filmed our end-of-the-year show and tell, where participants from the afterschool program and Five College environmental sensing class presented about their projects.

While planning my trip to visit Phil in Champaign, I wanted to arrange to visit Makerspace Urbana. Phil had told me about it before, but I hadn't managed to get there. We posted a note on their Facebook page and a comment in reply suggested we stop by the Fab Lab too. (I was pleased to see that they have a Drupal site.) We actually ended up going there first.

It was incredibly cold with strong wind when we arrived at the Fab Lab -- so cold that the parking meters were all failing. Phil spotted the parking enforcement guy who assured us we wouldn't get a ticket, so we headed in out of the cold.

The FabLab is on the UIUC campus and is in an old building that was essentially unused. It had a few groups functionally squatting in it, but was so decrepit and dirty as to be unusable for most purposes. Someone with university connections pulled some strings to put the makerspace in there and found a pot of money to get it set up, although a lot was done with sweat equity by volunteers who did much of the cleaning and setting up.


The Fab Lab has several rooms. You enter between a computer lab and a 3D printing lab. Past the computer lab, is a textile room that also serves as a kitchen (coincidentally, they pointed out, and not due to gender issues.) In the textile room are several embroidery machines that can be used to make patches -- a particular interest of Phil. Past their 3D printers (they have a couple of generations), they have a laser cutter -- one of the few really big-ticket items. Beyond, is a room with soldering stations. In a back room, they have some milling machines, one made from a Dremel motor tool and an arduino with a motor control shield of some kind. They're hoping to manage this room in coordination with the architecture program that has common interests in milling, but it looks like the arrangements are still being worked out.

The kitchen was really just a spot on the counter where communal food could be prepared and shared. They indicated that this was important, especially in their space due to the layout. They mentioned that in some spaces, where people sat around tables, there were more opportunities for social interaction. But in their space, where benches were along the walls, many people would work on their project with their back to the rest of the room, so having a place with food, that could draw people away from their projects where they could congregate and socialize, was really important for building community.

The next day, we stopped by Makerspace Urbana, which is in the Independent Media Center. I was particularly interested because I thought we might find some commonalities as we're building our Makerspace with Amherst Media. It turned out, however, that the entities are actually quite distinct -- almost unrelated. The Makerspace pays rent (quite inexpensive) and is managed totally separately.

We arrived just as it opened. It was smaller than I had imagined -- only room for 15 or 20 people tops. They had an arduino-controlled illuminated pride flag near the entrance that had been an earlier project. They used it for a fund-raising thermostat earlier, which seemed like a great idea. They had a common room with small 3D printer and a sewing machine and a back room with storage, where people could keep projects and supplies.

Their financial model is to charge a sustaining membership fee of $15/month and give "key access" for $25/month, where an existing member needed to vouch for you to get key access. This was sufficient to pay the rent, which had been a big goal of the fundraising effort.

I was excited to hear about the Makerfest that they had organized and were organizing again. They had looked into using the Makerfaire name, but found that it was burdened with a lot of restrictions, so they called theirs makerfest so they could do whatever they wanted. They had drawn in more than a thousand visitors and gotten a lot of publicity from the event. This is a goal I think we could set for ourselves.

I asked whether they'd had any problems or issues that required them to create policy and they really couldn't think of anything. They had created a "code of conduct" to head off potential problems early on (as we've done), but hadn't really had any problems they could point fingers at. Their main suggestion was to not get discouraged when things were slow. They had found dips and ebbs in participants as old people moved on and new people got involved, but found that overall just providing a reliable place for building community was the most important thing. Although they agreed with the Fab Lab that food was important to.

I really appreciated the warm welcome of Colten, Virginia, Jeff, and Eric. I got a lot of ideas to bring back to help build Makers at Amherst Media.
