Death by PowerPoint…literally…

Posted in Computing, Education, General, Politics, Science, Writing on August 19th, 2006

OK, I promise to stop with the PowerPoint bashing Real Soon Now, but the situation is just so terrible that it’s hard to walk away.

In reading this thread from Tufte’s Q&A thing (sort of like his blog), he points to this post from the Arms and Influence blog, which quotes Thomas Ricks’ book Fiasco. Apparently the geniuses in the Bush Misadministration have taken to replacing direct orders and clear plans with PowerPoint Phluff, leaving the well meaning folks at the Pentagon struggling to make sense of it all. Check out, for example, this truly wondrous bit of Phluff that purports to explain how something as complex as the occupation phase of the current Iraq war was going to work:
PowerPoint Phluff explaining how the occupation phase of the current Iraq war was going to work.
Ah, right. I know exactly what to do now…

It’s worth repeating the conclusion from the Arms and Influence piece:

The Iraq disaster did not happen because someone in the JTF-IV planning group or the Office of the Secretary of Defense (OSD) couldn’t write a good PowerPoint presentation. The problem was that anyone used PowerPoint to plan a war. Ricks is absolutely right in saying that only the most careless individual, in love with information technology for its own sake, would misuse technology in such an obvious fashion. Unfortunately, these are the people who planned and executed the Iraq war, and many of them are still prosecuting America’s wars.

BTW, Ricks give an excellent interview on The Daily Show recently. I suspect that Fiasco would be a very worthwhile (if quite depressing) read. After a little skimming I also was surprisingly impressed by the Arms and Influence blog (the title didn’t seem like my cup of tea). His description of flying on the day when the “liquids plot” broke in Britain is thoughtful and retains an impressive sense of perspective under difficult circumstances.

A wonderfully damning indictment of PowerPoint

Posted in Computing, General, Science, Writing on August 19th, 2006

In prepration for coordinating our CSci senior seminar course here at UMM, I’m reading the second edition of Edward R. Tufte’s excellent pamphlet The cognitive style of PowerPoint: Pitching out currupts within. I’d used the first edition a few years ago and really liked it, and the second is just has brilliant.

Tufte’s work is massively quotable, so it’s hard to choose, but I think this bit pretty much sums up the deal:

Both the Columbia Accident Investigation Board and the Return to Flight Task Group were filled with smart experienced people with spectacular credentials. These review boards examined what is probably the best evidence available on PP [PowerPoint] for technical work: hundreds of PP decks from a high-IQ government agency thoroughly practiced in PP. Both review boards concluded that (1) PowerPoint is an inappropriate tool for engineering reports, presentations, documentation and (2) the technical report is superior to PP. Matched up against alternative tools, PowerPoint lost.

The short version is that PowerPoint frankly sucks as a medium for conveying complex and information rich material. For example,

Compared with the worldwide publications shown here, the PP [PowerPoint] statistical graphics are the thinnest of all, except for those in Pravda in 1982, back when that newspaper operated as the major propaganda instrument of the Soviet communist party and a totalitarian government. Doing a bit better than Pravda is not good enough…

It’s a brilliant pamphlet and only costs $7, so there’s really no excuse for rushing out and getting one if you haven’t done so yet.

I’m particularly struck by this because a few days ago we had two classic mis-uses of PowerPoint at our opening faculty/staff convocation of the school year. One used a retina destroying color scheme motivated (I think) by a desire to work with our school colors, which almost certainly weren’t chosen for their typographic suitability, and another presenter suffered from the all too familiar problem of constantly jumping to the wrong slide and struggling to navigate to the desired location. These were bright, skilled people who regularly (and rightly) represent our institution out in the world, and their choice and use of PowerPoint made them look, well, silly.

Sigh.

Much like Peter Norvig’s excellent re-casting of the Lincoln’s Gettysburg Address as a PowerPoint presentation:

Good morning. Just a second while I get this connection to work. Do I press this button here? Function-F7? No, that’s not right. Hmmm. Maybe I’ll have to reboot. Hold on a minute. Um, my name is Abe Lincoln and I’m your president. While we’re waiting, I want to thank Judge David Wills, chairman of the committee supervising the dedication of the Gettysburg cemetery. It’s great to be here, Dave, and you and the committee are doing a great job. Gee, sometimes this new technology does have glitches, but we couldn’t live without it, could we? Oh - is it ready? OK, here we go

If you’ve never read it, drop everything and go there now!

The scary power of search logs

Posted in Computing, General, Politics on August 8th, 2006

Stay off those rails
My experience is that it’s often hard to get people excited about things like Google’s highly detailed records of what you’ve been searching for (e.g., check out “Verbatim: Search firms surveyed on privacy” for a survey of what four major search engines collect, “FAQ: When Google is not your friend” for further analysis, and “Keeping secrets” on Slate for a related discussion). Responses often run along the “I have nothing to hide” or “Only criminals/bad people would have reason to worry about that” vein, but an underlying theme is often a sense that there’s really nothing useful/interesting to be learned from trolling through search terms.

Recently, however, there was a leak of the search histories of over half a million AOL users over a three month period. No names are attached, but they do have user numbers so you can pull together all the search terms from single individuals. Declan McCullagh (of the Politech mailing list) has sifted through some of it in “AOL’s disturbing glimpse into users’ lives” over on CNet, and it’s a real eye opener. And while there are clearly some deeply scary and deeply troubled people in his discussion (makes for better reading), step back for a moment from the pathologies and think about just how much these small subsets of these people’s search histories tell us about them and their lives. And then think about how much of your life (good, bad, and slightly smelly) could be reconstructed from your search history. Then throw in some web access logs, your Amazon search and buying patterns, your e-mail address book, and IM logs.

To misquote a fairly paranoid TV show: The data are out there.

And they can be accidentally leaked, deliberately sold (with or without the knowledge of the holding company), or subpoenaed. Currently there is very little legal protection of your privacy in the realm of search terms; basically all you’ve got is the good will and good word of the search engines, and faith that the courts care and get it enough to look after your privacy interests. As the AOL situation makes clear, though, mistakes happen, and lord knows that not all judges are equally together on these issues.

What to do? Not clear that there’s a simple “fix it” action here, but at a minimum it would be useful to spread the word and help raise awareness. Bug your favorite search engine and let them know that you have expectations of privacy and are willing to vote with your feet. Supporting the work of groups like the Center for Democracy and Technology and the ACLU wouldn’t hurt, since they’ve both been pretty front-line on these and other important privacy issues. You might also take a librarian to lunch, since they’re a pretty cool bunch when it comes to protecting the privacy of their users.

The more hard-core among you might explore the many anonymous browsing tools. These are usually just a server that sits between you and, for example, Google, so Google’s records show all the searches for lots of people (including you) as coming from the anonymous proxy. This sounds good in principle, but in some sense you’re just moving your trust from Google to the proxy, since their logs can allow people to reconstruct your search (and browsing) history. If you’ve got toys, you could set up your own proxy (you do trust yourself, don’t you?), but then you lose the anonymity that comes from mixing your history in with that of hundreds of other uses. In other words, this is a complicated road to travel, and you’d best do your homework if you really want to anonymize your history.

Be careful out there. And don’t talk to strangers (at least not too often)…

Chalk up another one in favor of the liberal arts…

Posted in Computing, Education on January 1st, 2006

Roman glass
…and from a somewhat unexpected venue. CIO.com is (in their own way) touting the value of a liberal arts education in computing. Maria Klawe, the author of the piece, feels that “career opportunities in computer science are at an all-time high” and:

We’ve got to spread that message among students from a rainbow of backgrounds, or risk becoming a technological backwater.

That “rainbow of backgrounds” is where the liberal arts enter the picture:

computing-related jobs are no longer an isolated component of American industries; IT underpins every function of the business community—market research, product design, finance, strategic planning, environmental issues—every aspect of doing and leading. That means these jobs are not only vital but fun. They require people who have strong technical knowledge but who also can work and contribute in a much broader realm. A recent New York Times article dubbed this kind of IT professional “the renaissance geek.” The leaders of Microsoft, Google and other companies have made their point clear: Give us more well-trained, well-rounded computer scientists!

Yeah - “renaissance geek”… Gotta love that!

The article goes on to provide several suggestions for how the business and academic worlds can work to encourage and develop this next generation of Renaissance Geeks. These include thinks like making a computing course a requirement for more undergraduates (and make sure they enjoy it), make connections to other departments/disciplines, and hire more female faculty.

UMM used to require all our students to take a computing course, but this requirement was dropped 6 years ago in the belief that the high schools were getting up to speed and providing our incoming students with the backgrounds they needed. I think there’s a growing sense on campus that they may not have worked out as well as we’d hoped, and I know our experience in Computer Science and UMM is that we’ve seen a much more homogenous group of students (white males with a strong leaning to the more stereotypical geek) than we did before the requirements changed. Making a change to the general education requirements like restoring this requirement wouldn’t an easy thing, though, and we run the obvious risk of entering into an unpleasant “Why is your field more important than my field?” sort of debate since (obviously) every discipline at UMM is crucial to being a well rounded citizen in the 21st century.

We’re doing a pretty good job on the business of making connections to other disciplines, in part in an effort to broaden our appeal in the wake of the aforementioned change of requirements. We’ve got interdisciplinary programs in media comutation (with Studio Art and Speech/Communications) and bioinformatics (with Biology and Chemistry), and a new faculty in Philosophy has started a conversation on a possible program in Cognition that will likely include us in some form. There’s more than can be done here, but I think the wheels are turning in a useful way.

And, finally, we’re rocking pretty hard on the gender diversity in our faculty as we currently have 3 of 5 being women, which puts us well ahead of most other programs.

I’ll wrap with this final quote:

At all levels, schools need to make computing attractive to ambitious students who have a fondness for technology but also want to fold in other skills and interests. These are the students who are going to be leaders and make a difference in the world, and they include women and minorities and the full cross-section of society.

Amen, sister!

A rockin’ UMM CSci reunion dinner

Posted in Computing, Education, Events, Travels on October 9th, 2005

CSci reunion dinner Oct 2005
Nick Hopper (UMM ‘99, now a tenure-line CSci faculty at the Twin Cities campus) invited us out to the Twin Cities’ Computer Science and Engineering biennial technology forum/open house, which was very cool. At various times it looked like as many as 10 or more UMMers might make the trip, but in the end mid-terms and on-campus events trimmed things down to Emily, Elena, and myself.

The scramble to get ready was pretty crazy, but all worth it as it was an excellent event and I got to meet some interesting new people and hook up with folks I hadn’t seen in a while. A major highlight was the informal UMM CSci reunion dinner last night after the open house was all over. We had 20 UMM folks in all, plus two wee’uns, for a fun and tasty evening.

The U of M discovers Jabber

Posted in Computing, Education, Politics on September 7th, 2005


Mike A. just brought to my attention the fact that the U of M has set up an all-U IM server using the Jabber protocol. Their reason for this move?

Jabber is an open, XML-based instant messaging (IM) technology. By hosting our own Jabber servers, the University can provide safer and more flexible instant messaging for its users.

The ability to host IM traffic on University servers allows us to protect our users against sophisticated virus and worm attacks, such as the ones that spread over AIM in Spring 2005.

All this seems quite sensible, and I really like Jabber (my Spring, 2004, Software Design class wrote Jabber based chat clients), but I’m not real convinced that this is going to fly. So far they’ve done pretty much nothing to inform the university community that they’ve done this, and I’m totally not sure that they’ll be able to convince the students, who have IM contacts all over the universe (most of which use either AIM or MSN), to switch over and use this. I wish them luck, but I’m not putting money down.

And what is up with the U’s continued schizo attitude towards Open Source tools? Last year they adopted Oracle’s on-line calendar system (internally called UMCal) without even considering an open source alternative. And they continue to promote the use of WebCT despite the existence of several plausible open source alternatives (some of which the U is even helping support, at least on paper).

Yet, when they wanted to set up an IM server, they go with the open source Jabber option. Hmmm… Why is that? Maybe because there were no good proprietary options?!? Arghhhh…

And while I’m ranting, I’ll express my concern about what I perceive to be a growing trend both within the larger U and here at UMM to build this type of closed, inwarding looking solution (”We support IM, but you can only talk to U of M people.”) in response to real and perceived security issues. A vibrant, successful university is almost certainly an outward looking institution, aware of and part of conversations and activities that span the entire globe. This move to closed, internal communications networks is inherently inconsistent with the mission and goals of the institution.

PeeZed manages to handle the many security issues surrounding his highly successful (and wonderfully “controversial”) blog all on his lonesome while still inviting and encouraging the participation of a large and active community. You’d think that the massive resources of the U could do better than running around locking all the doors.

Maybe I should ask them to disallow phone calls to my office from off campus. Then I wouldn’t have to talk to those pesky colleagues, alums, employers seeking a reference for a student, and that woman who wanted to interview me two weeks ago about a security clearance for a recent graduate.

Think of all the blogging I could do … uh … work I could get done without all those tedious interruptions…

It’s a shame more people can’t write so well about tech

Posted in Computing, Politics on July 20th, 2005

John Naugton
WeatherGirl just handed me a recent copy of The Observer, an excellent British weekly that she subscribes to as part of her campaign (along with listening to BBC radio on-line) to both keep track of what’s happening “back home” and to get her news from organizations that regularly provide intelligent, thoughtful reporting.

An excellent example of this is John Naughton, the author of a regularly technology column in the Observer, and the author of the piece WeatherGirl was handing my way. The column in question is an analysis of the recent (and much discussed) Supreme Court decision regarding Grokster and StreamCast Networks which has been seen by many as a huge defeat for the peer-to-peer (P2P) file sharing, and victory for the big players in corporate media that are trying to desparately to maintain at least the illusion of their control over their content.

Most writing on this and similar issues tends to suffer from serious myopia as the writers typically understand either the technological side of the issue or the socio-political-economic side of the issue. It is sadly all too common that writers understand neither of these sides, and very rarely do they understand both. Naughton is the happy exception, who really understands the world of the nerds that drive the technical changes that constantly ripple through our lives, and can write with wonderful perception about the larger context that these issues live in.

In the column in question, for example, Naughton understands (and clearly explains) important differences between Grokster and StreamCast Networks and the classic Sony decision that is often quoted as precedent. As he nicely points out, a better analogy to the Sony decision is BitTorrent, yet sadly most writers on the issue (not to mention many of the policy makers involved) probably know little about BitTorrent and less about its place in this complex set of issues.

In short, John rocks, and you could do much worse.

Oh, and I should mention that he also helps support the interesting Living without Microsoft site.

Author’s interview on Flickr

Posted in Photography, Travels on July 17th, 2005

An eye on the dream
I’ve never participated in one of these “Answer N questions on a theme” memes, although I was sorely tempted by these questions from ScribblingWoman (see answers by New Kid and Pharyngula for my inspiration). Unfortunately it came up at a bad time in the semester, so nothing ever happened.

However, I just got an invite from hkvam to contribute to an “Author’s interview” meme on Flickr. I’ve never actually been personally invited to participate in such a thing and flattery and ego will go a long way in my petty little universe, so here I am answering some semi-random questions about my photography. This will probably get a bit long and rambly; don’t say you weren’t warned :-).

Not surprisingly, I also posted this (with some minor changes) over on Flickr.

Your iPod broke my metaphor

Posted in Music, Politics, Radio on July 11th, 2005

Dagstuhl desk
The BBC has long (like since 1942 long) run a program called “Desert Island Discs” (with numerous other broadcasters running similar programs). The basic setup of the Beeb’s version is you bring in some person of interest (a celebrity or author or politician or whatever) and ask them what they’d take with them if they were going to be stranded indefinitely on a desert island. They get the King James Bible and the complete works of Shakespeare for free (it is the BBC, after all), and then have to choose eight recordings to take with you (as well as an additional book and a luxury). They are interviewed about their choices, with their musical choices interspersed amongst the chat.

While it’s often interesting, it’s often less so (not all these people are that interesting underneath their celebrity), and I am by no means a regular listener. I’ve always been intrigued by the idea though, as part of my love of Top 10 lists and the like. Every now and again I think about what I’d say if someone asked me, and I’ve come to realize that modern technology has fundamentally broken the metaphor. The whole thing was premised on big, heavy objects which forced choices in the face of limited resources. (Check out, for example, the excellent program on John Lennon’s jukebox, where he could only carry a few dozen singles with him on tour.)

When my sister was first heading to the Galapagos 1.5 years ago, my dad and I bought her a small, inexpensive, solid state (for low power consumption) MP3 player. She was going to be on the islands for several months, including several weeks on Española, an uninhabited island mostly covered in lava boulders (with the smattering of marine iguanas, horseshoe crabs, and Booby poo to break the monotony). This was about as close to a desert island experience as most of us will ever have, but we were able to spend less than $100 to give her the ability to take vastly more than eight recordings. And that was 1.5 years ago. The same amount of money today would buy her far more capacity, and there’s every reason to believe the trend will continue into the significant future.

WeatherGirl, Sub-Evil Boy, and I have a second generation 10Gb iPod we bought several years ago, which is truly wonderful on long car trips. (The 14 hour drive down to my folks in Arkansas is probably another modern equivalent of a desert island given the state of American radio and the diversity of our tastes.) We each choose about 2.5-3 Gb of music, load it up, and hit random. It works really well, especially if we all avoid overly long pieces and I don’t put in too many really weird bits.

3 Gb is an enormous amount of music compared to the eight recordings from Desert Island Discs, and you might think we wouldn’t have to choose at all. The other two don’t (much), but I definitely do. We (meaning mostly me) have over 1K CDs, and I have well over 10Gb of music on the Mac in my office, so choose I must. At first I agonized over it, but I’ve learned to avoid that by simply have the computer choose 2.5 Gb of random music from a list of stuff I know I like (mostly things I’ve rated as 4 or 5 stars). Sure, I’m not guaranteed to have “Lord, I just can’t keep from crying” by Blind Willie Johnson, but I might get to stumble something obscure and strange from David Lee Myers’ Arcane device: Engine of myth (an album composed entirely by sampled and arranged electronic feedback sounds). I get what I get, and it’s almost all really good, and that’s a wonderful thing.

Starting last year I started doing something similar in my First Year Seminar (FYS) course on American Roots Music. Instead of sweating over the careful construction of weekly listening lists (which I was never entirely happy with because I always had to leave something “crucial” out), I now let iTunes pick 30 minutes of random music from the big pile. I sometimes do a little editing (we’ve already heard that artist before, or that’s really too long to justify inclusion), but mostly I leave it alone. At first I was pretty nervous about stepping back that much, but it in fact worked out really well. We got to listen to and discuss a lot of cool music of many different types. This also allowed the combination of my general taste and sense of what’s important (which determines the pool the music’s being drawn from) and the students’ tastes (and sense of surprise or confusion) drive the discussion in interesting ways.

(I’ve also thought of taking this approach with a show on KUMM, but it would have to be different from our family show and I doubt I have time for two shows at the moment.)

So it seems that the old metaphor of Desert Island Discs is arguably seriously broken, and that replacing it with “What would you put on your huge MP3 player?” just isn’t going to work as a replacement metaphor, at least for a radio show. (MusicMobs, however, does suggest an interesting on-line way to deal with the vast amount of music in people’s collections.) Memes like “Ten random songs on Friday” are arguably closer, but the sample is so small that really unrepresentative things can happen, so many people feel the need to manipulate the list (or at least apologize for it).

Weirdly, the metaphor also wouldn’t have made any sense 100 years ago when most people had never heard recorded music, but carried it around in their heads and made it on their front porches. “What do you mean I can only take 5 songs? I know dozens! Do I have to forget the rest? Am I not allowed to write any while I’m there?”

Everything old is new again? Probably not, as we have access to a vastly larger and broader spectrum of music now than at any other time in human history. But it’s not all completely new, is it?
