Mac memory

Published by matt under Uncategorized


It’s possible in a few weeks I’ll want to find memory for a Mac; in particular, I may want to order memory for an iMac. If that’s the case, I’ll have to go through my previous entries and find this one, where I left myself a note.


What I don’t know is how to upgrade the factory slot; is it the same on the 1GHz 17″ iMac as on earlier models?


I’m just not keen on a $400 pricetag to upgrade the machine to 1GB of RAM; then again, letting them do it doesn’t void the warranty. Oy.

No, I’m not interested.

Published by matt under Uncategorized


I always like it when friends feel compelled to fill you in on the state of things in their life. It makes me feel like I’m part of someone’s life, even though I’m not in the same place as they are.


I just thought you should know I’m on holiday in Greece. The sun is shining, the dodgy Greek wine is flowing and life is grand.

Sorry, just thought you might be interested ;-)


NO! I’m not interested! I don’t want to hear about your new cars, how you won the lottery, that you’re sunning yourself on the beaches of Portugal (I got a text for that one, not an email), Greece, or anywhere else that has sand and sun! I’ve got lots of work to do, and it looks like it’s going to rain all week in Wales. Grrrrrrr…


;)


Actually, I’m happy to be in Wales. I’m happy to be seeing family and friends in a few weeks, which will be cool enough. Now, if I could get the family and friends to the beaches of Greece, that would be even cooler…

Reason #328 for visiting LA if you’re French

Published by matt under Uncategorized

Reporters Without Borders today protested against the detention of six French journalists on arrival a week ago at Los Angeles international airport to cover a video games trade show and their forcible repatriation after being held at the airport for more than 24 hours.

They were subjected to interrogation sessions and six body searches. They were handcuffed while being moved from one place to another, and they were fingerprinted. One official told Alfonsi he would not be able to return to the United States again. They were put on a flight for France at around 4 p.m. the next day and were not able to recover their passports until the aeroplane made a stopover in Amsterdam.

Emphasis mine. Via Reporters Without Borders. Yes, I don’t know “the truth.” I’m sure these guys were potential terrorists, a threat to my homeland’s security. Or perhaps the immigration officers in LA were demonstrating their version of “freedom fries.” You decide.

Six body searches.

“I did this!”

Published by matt under Uncategorized

Joe points to a Washington Post article re: possible outcomes of student’s use of email and IM slang. After spending the afternoon with 12-14 year old students again, his pull-and-comment spawned the title of this post:

Students also love writing online, seeing it as recreation rather than schoolwork. I wonder about this. How long will we be able to say that before it becomes so commonplace that it IS seen as schoolwork?

I did this. As long as students can easily point to something they did and share it with all those other people via IM/email/discussion groups/their favorite MUD, then writing online will have a fundamentally different character than writing “for the teacher.” There is a performance aspect to writing online–someone might be watching!

In reviewing the literature regarding the use of the LEGO Mindstorm in the classroom, something that is rarely teased out is the role of performance w.r.t. motivation when using the Mindstorm in an educational setting. Said simply: when teachers use little robots, they expect the students to compete, share, or otherwise perform their work for others. I suspect that this may be the common thread here, moreso than any Piagetian notion of the bricoleur, or builder-learner (eg. building is to learning as writing is to learning).

Postgres is cool

Published by matt under Uncategorized

I know this is awful, but I’ve never sat down and written an application that actually uses a proper database for storing data. This is, considering some of the things I’ve written, horrible. This evening, I’m rectifying that situation. I installed Postgres, (went and played squash, had a few slices of bread), came back to the lab, panicked that I couldn’t download spgsql (SourceForge was down all afternoon), obtained it from another Schemer, and then set to work.

The project I’m working on involves lots of spreadsheets, which I’ve converted to XML using the Perl Spreadsheet:ReadExcel module. This evening, after getting comfortable with the spgsql code, I sat down and created a bunch of tables on my new Postgres installation, and wrote a loader for one of the tables. It happily chugs through a directory full of files, and crams the database full of nifty stuff. I was able to look at the contents with phpPgAdmin, which is cool as well. (Most importantly, it lets me see if I’m doing things correctly.)

Now I’m able to do cool little bits like


(let* ([res (recordset-rows
              (send (current-connection) query
                     "select * from subjects"))]
       [total
         (apply + (map (lambda (v)
                         (vector-ref v 5)) res))])
  (exact->inexact (/ total (length res))))

and I get out 25.801020408163264! (Yes, it’s all in Scheme. What else?) I would get 5057/196, except for my request to make it an “inexact” number. :) So, the people in my database are roughly 26 years old. How cool is that!?

When I get excited about things like this, it’s either because it’s exceptionally cool when things just work (which they did), or I’m tired. Clearly, it’s a little of both. Tomorrow I’ll finish writing the loaders, and then I can focus on writing code to support exploring the data, instead of all the time I’ve spent mangling and managing the data. What’s nice is that a bunch of questions I wanted to provide support for will become much easier to express in code when I can do a SELECT and use higher-order procedures to manipulate the results (not to mention having the ability to intelligently JOIN results in the DB first…).

Yes, I went URL happy here… definitely time for bed…

Guidelines for (researchers|educators|students) with weblogs

Published by matt under Uncategorized

Ed Cone is a writer for Baseline, a technology magazine; he also maintains a weblog. Today he has an interesting post that outlines guidelines for journalists for weblogs. I’ve modified his list slightly to make it fit more with the theme of CS-ED.org: researchers, educators and students taking part in the educational enterprise. [After translating these, I think they need some revision, but could be developed more fully into some good guidelines for blogging in educational contexts. Perhaps three versions are needed: for researchers, instructors, and students?]


  • Don’t dress your weblog in your work uniform.
    If your weblog is hosted on your institution’s servers, include the standard disclaimer and you should be fine. However, if you’re running your blog off-site, keep in mind that institutional imagery will be seen as a dilution, not a strengthening of the school’s brand.


  • Don’t write on company time.
    This is probably the least problematic point for academics, but students in the classroom certainly should be wary.


  • Don’t compromise your reputation, or your institution’s.
    If you are within the guidelines of acceptable content at your institution, you should be fine. However, consider carefully what is “acceptable” in the larger context; if your weblog brings the wrong kind of attention, then it might be decided that it is “unacceptable” in the eyes of the administration. This is especially the case if you are criticizing some aspect of your work or relationships at the institution–it may easily come across as a personal attack, which most likely will not be tolerated.


  • Don’t scoop your day job.
    With respect to academic writing, this is the most difficult line to draw. You want to write about things pertinent to your work, but you want to maintain ownership and the right to publish that work. To this end, use technical reports and the like for major placeholders, and keep discussion of your ideas a bit more general on your weblog. This is, perhaps, less of a concern when discussing methodology and classroom plans then research agendas.


  • Maintain whatever objectivity your job requires.
    Someone will Google you someday. Make sure the voice you use on your weblog is the voice you want a future advisor (students looking at graduate work), employer (graduate students and young faculty), or supervisee (established faculty) want the world to hear.


  • Loose lips sink careers.
    Know what is public and private. Keep private things private.


  • Try not to be a jerk.
    I think this has been covered.


  • Work with the boss if you can.
    What does this mean in an academic context? Difficult to say.


  • Fake it if you have to.
    If you want to maintain a weblog, but don’t want your name associated with it, don’t. However, I don’t think this is in the academic spirit, and as such don’t recommend it (unless the weblog is intended to be wholly and completely separate from what you do, which is not the intent of CS-ED.org blogs, for example).

Respect for The Student

Published by matt under Uncategorized

[ This is post one of two regarding my views on the role of respect in educational settings. --MCJ ]

Respect is foundational to all of my thinking about the classroom.

This week, three of us from the University of Kent made our way into a secondary school thirty minutes Northeast of Canterbury. The school is not particularly well funded, and not a grammar school (meaning that the students did not “test in” to the school with high marks on exams). They have a wide range of students, a number of whom (we are told) have bad situations at home or behavioral conditions of one sort or another. One teacher, when we were discussing coming in to do volunteer work with the LEGO Mindstorms kit told us that we’d loose everything that wasn’t nailed down to theft, the kids would hate anything we did, and we would most likely be eaten alive.

As I am here, writing this now, we were not eaten alive. Nor was anything stolen that I know of, and I thought the students had an excellent time. These were 8th and 9th year students, roughly 13, 14 years old. If I had to guess, I’d say that they enjoyed themselves immensely. They build kinetic art, learned to program (a little bit, with RoboLab), and I introduced them to microworlds, or artificial universes, where we can simulate thousands of little robots, instead of just playing with one.

So what does this have to do with respect?

One of the instructors in the school stayed on to watch the hour-long course we ran, as well as a school tech in case we ran into difficulty with the hardware. The instructor’s tone, after we were done, was one of… condescending surprise? “Well, it looks like you survived…” Yes, I survived, thank you very much. After spending 24 hours a day, seven days a week with disadvantaged kids from South St. Louis at YMCA Camp Lakewood (an incredible, wonderful summer), one hour with some kids from the SE of England can’t possibly be a problem.

Furthermore, he opened his mouth twice to speak to the students during our session. Once to raise his voice and glare at two boys who were fooling around, and once to tell his (apparently) “favorite” student to push in all the chairs. The two boys fooling around were right in front of me, and were jabbing and slapping at each-other; I was just about to put a stop to it with a simple request (they were having fun, and I ended the session 4 minutes early–what do you expect?). Instead, a voice (and The Glare) comes in from across the room, a veritable shout and growl, telling them to cut it out or else. As The Favorite finally was making his way out of the room (he was one of the last out), a commanding tone issued forth: “Stewart, push in all the chairs before you go!” (Names changed to protect the innocent.) There was no request, there was no option. When we were doing a pseduo-debriefing after the session, we commented on a few hiccups we had throughout the period. This inspired the instructor to ask more than once if it was “short haired, short boy” or “was his name ‘Stewart’?” He clearly had singled this boy out, and was not interested in improving his condition, or working with this child–he was interested in controlling and commanding him.

It was stomach-turning. There is no excuse for this. I can do more with a kind word and polite request any day than with a command and a growl. If you feel you absolutely must command in a classroom, students will respect you all the more if it is your last resort, not your modus operandi. None of these students had any kind of genuinely severe behavioral disorder (which I have relatively little experience with in the classroom), and instead seemed like a bunch of 13, 14 year-old children: energetic, confused, excited, disaffected… everything you would normally expect.

If I went to that school, and other teachers had even remotely similar teaching styles, I’d honestly hate my life.

Welcome to Portland! Here’s your Star Destroyer!

Published by matt under Uncategorized

While working out summer travel, friends from Bloomington (who now live in Oregon) pointed out that Seattle isn’t too far away, and we should get together while I’m on the Left Coast. Heather says:

… of course, if you come down here, you could enjoy your choice of vacation activities:

(1) Sip lemonade while lounging on our lovely new patio.
(2) Investigate the recent additions to our board game collection.
(3) Ride the famed MAX light rail out to our highly educational and animal-friendly zoo. (Much better than that nightmare of a zoo in Indy.)
(4) Climb 600 feet in a mile to the top of Multnomah Falls and peep out over the edge.
(5) Picnic at the scenic Oregon coast.
(6) Get lost for a few hours at the Powell’s bookstore.

Sadly, Peter has already disassembled attraction number seven — the LEGO star destroyer.

That’s an advertisement for Oregon if I’ve ever seen one. Powell’s alone is enough. I’ve grown quite fond of Murder 1 and Foyles (both excellent bookstores up in London). However, Powell’s is a full city block in size…

mmm… massive used bookstore. :)

Two articles from CIE

Published by matt under Uncategorized

As a result of finding the list of online ed. journals, I started browsing. From Current Issues in Education:

[ Research Methods ] Typology of Analytical and Interpretational Errors in Quantitative and Qualitative Educational Research (must read!)

[ Affective Domain ] Ethos and Pedagogical Communication: Suggestions for Enhancing Credibility in the Classroom

The first article is a must-read; from a quick skim, it looks like a nice overview of pitfalls. Certainly good reading for grad students in CS-ED. The latter just looks interesting to me.

Online Education Journals

Published by matt under Uncategorized

Joe Luft (BrooklynBloggEd) points to open-education.org; in particular, a list of on-line, peer-reviewed journals pertaining to education.

Excellent resource.
