I was talking about my recent posters the other day with Teetee/Pi. He was asking me questions about how to interpret Figure 3 which shows the clustered output that results after feeding similarity data into the multidimensional scaling algorithm. I didn’t have a copy of the page handy, so I pulled up the PDF version and happened to notice that the one-page version of my poster, destined for an ordinary sheet of paper, no longer had my name or my e-mail contact address on it. The only thing on it was a pointer to the three-page version of the poster on this web site.
Oops! Oops! Oops!
I was short on time when it was decided that a handout-sized version of information was needed, so I’d had my Sweetie build me the single page and the three-page versions based on the finished poster design. He got a little overzealous about saving space and, well, managed to axe the contact and affiliation information. It was missing off of the three-page version, too.
Alas, I didn’t discover this until after the Open Day, so the damage has probably already been done. Nevertheless, I’ve prepared new versions of both documents with this information intact and added page numbers, where appropriate, to boot.
Live and learn! Don’t be so concerned with the content that you fail to see the forest through the individual trees!

I was trying to get X11 launching applications from the department’s Solaris server again. As before, I couldn’t immediately get it to work because of “magic cookie” authentication issues. I reviewed my previous notes which pointed to an article at MacWrite.com which might have helped before, but it was suddenly unavailable. The WayBack machine to the rescue. As soon as I had edited my /etc/ssh_config file to include the following information, I was good to go again:

Ciphers blowfish-cbc, aes128-cbc, 3des-cbc, blowfish-cbc, cast128-cbc, arcfour, aes192-cbc, aes256-cbc
Compression yes
ForwardX11 yes
Protocol 2,1
RhostsAuthentication no
RSAAuthentication no
UseRsh no

Note: It may be necessary to take out the extra spaces between items in the Ciphers list.

That, of course, assumed I had already had an entry in my ~/.cshrc file to the effect of:

setenv DISPLAY :0.0

Then, I can simply use a variant of the following to, for example, launch dtterm:

ssh -X eingang@machine_name.com /usr/dt/bin/dtterm

MATLAB, unfortunately, doesn’t seem to work at all. It used to generate all kinds of font errors looking for various Sun fonts, but it did launch. Now it launches with all the font errors (see sample below), shows the graphical about box and then we’re in the command line environment instead of the GUI development environment.

Font specified in font.properties not found [ urw itc zapfdingbats medium r normal * %d * * p * sun fontspecific]
Font specified in font.properties not found [ urw itc zapfdingbats medium r normal * %d * * p * sun fontspecific]

Note: All the ‘-’ characters appearing inbetween [] above have been changed to spaces to render better in HTML.

I’ve mailed the Mac technical support person to see if they have any ideas as to why it no longer works and how it might be possible to fix the font errors.

By the end of April, I seemed to be stymied in my quest for an affordable copy of MATLAB that I could run on my local laptop. The university maintains a license pool for the base software plus toolkits. I do have access to run a copy from the license server when I’m on campus. It actually worked off of campus too, when I’d been told it shouldn’t, but that turned out to be a mistake. When I reported it, the firewall was closed to the outside world for requests for the license server. That’s where honesty gets you: no MATLAB accessibility from anywhere with an Internet connection.
I was hoping to snag one of the concurrent licenses for my permanent use and offered even to buy an additional one for that purpose as that would be cheaper. I was told that I couldn’t have one and I should investigate the student version of the software. Unfortunately, the student version is only available to students in taught courses, not Ph.D. research students, so that wasn’t any good. I mentioned to Thufir that I’d been turned down, reportedly by the head of software/hardware procurement within our department. Thufir promised to see what he could do. Then, last week, I received an e-mail last week from the lab manager, the person in charge of the procurement. He offered, if somebody would pay for it, to install an academic version of the software on my university-owned equipment for only £525 (~930 US/780 €). That was just for the base software and not also for the toolkit I need.

Today was the Open Day for the Human-Centred Technology group at the University of Sussex. IDEAs , my research lab, is part of the overall HCT group and a major participatant in the organization and presentation of the Open Day event, the first of which was held last year. I was unable to attend or to help out much with the organization as the event fell outside my scheduled university days. It was decided that we needed copious quantities of posters and every Ph.D. student was expected to make a poster about their project. Apparently this was timely as second- and third-year students were also expected to produce a poster for the department.
I spent oodles of time in April designing the look of the poster and then populating it with text. The finished version of the poster looked pretty good in its A1 size (~90cm by 60cm). Designing the poster in the absence of any input and with lots of nice-looking graphics to possibly incorporate led to a poster that was quite dense and text-heavy, although it had a fair bit of white space, too. A week before the event, the Lab decided that we should also have colour handouts to go along with every poster. Just shrinking down my poster from its large A1 size to A4 (regular paper size) resulted in a page that was legible (but not for readers with poor vision) with tiny graphics. The EinSweetie, who had more time, took the original poster and produced a handout version with not quite so much of the text and graphics on it. As a lot of the crucial detail had been cut, we also decided to make a short multi-page PDF version of the original poster text which could be downloaded. The URL was included on the handout sheet.
Doing the poster was very interesting, especially after my longish absence from working on my Ph.D., as it helped remind me of some of the major issues arising out of my research. A look at the big picture is often very helpful in clarifying your position and your journey. My examination or generation of the big picture led to me to realize that I was developing the fingerprints and the methodology for producing them, but then I wasn’t using the notion of the fingerprint itself anywhere after that point — something I’d completely overlooked, being caught up in the minutia of analysis for ages. I was so struck by this and other revelations that I had them make up a second laminated full-page version of my poster to hang in my office to remind me of the big picture. Life is so much improved when you can see where you’re going.
