I’m having some trouble with the ‘open’ wikis that I established for the Tulane b-school in the wake of Katrina. They’ve been discovered by spammers and trolls. It’s kind of depressing that anywhere that someone can cause trouble or direct-market on the internet, they will. I’ve added a few hurdles to modifying the wikis and alterted the legitimate users, but I think at some point I may just have to password-protect the whole thing. I am Jack’s exasperation.

Running Resumes Post – The First
Today I did manage to get up at 05:00, run from around 05:15 to 05:35, and get to work by 07:15ish. I have the actual time in my log, but alas, I am too lazy to pull it out.
Swimming is important. Swimming makes the upper body strong. I really need to look up the pool schedule here at Wash U. I went through all of the trouble and expense of buying swim trunks and some goggles. I might as well use them.
Work today consisted mainly of filling out an AHA fellowship proposal, which I’m not exactly finished with. I’d say I’m 2/3 finished with filling in the forms, and then comes reference forms, mailing reference forms, inserting other documents into the pdf using Adobe Acrobat™, etc.
I also spent some time trying to figure out why Hermenegild’s laptop won’t run our visualization software correctly. It seems to be some kind of problem with a crossmojination of OpenGL libraries of one sort or another. After spending about an hour on it, and checking through all of the usual suspects, I left it to him to fiddle around with it and do some more googling. I’m a little disappointed in Ubuntu on this one, but it could be a cruddy chipset from Intel. It’s the i915 video chip, so if you have any Linux DRI/DRM/OpenGL experience with that chip, please do let me know.
That’s about all for now. There’s some musing going on on the Internets™ about whether Microsoft is really making a change with this online services crap. My guess is, no. They always put the cart before the horse. They design things first to bring in money, and second to perform a useful function. This is not the way of the coming world. The useful function has to be the goal. Making money is artfully tacked on in the background. Not that it shouldn’t be thought of… it’s more of a design issue with the function part.
Anyway, I’m waxing poetic. Here are today’s stats:

Grants.gov
Grants.gov has moved to requiring Windows-only PureEdge software in order to apply for a grant. Worse, their response to the scientific community’s outcry on this platform-dependence is to use VirtualPC with a copy of Windows. They reason that this is acceptable because Microsoft distributes VirtualPC with Office now. And we all know, EVERYBODY has Office. We pick it from the Office Tree of Giving.
This is the age of the Web 2.0™ The government, the self-same government that took Microsoft to task over lock-in, is moving from a well-liked, web-based platform (FastTrack) to some obscure piece of Windows-and-IE-only software?
What the hell is going on?
ADDENDUM 2005-11-02 @ 16:12:
Here is what I wrote to them:
Hello,
I am writing to inquire as to why the web-based FastTrack software has been abandoned for the Windows-only PureEdge software. PureEdge’s assertion that VirtualPC running Windows is an adequate solution for mac users is somewhat questionable. Furthermore, users of the various BSDs, Linux distributions, OS/2, plan9, Inferno, etc are left without any access. Is there pressure on PureEdge by Grants.gov to include support for other platforms? Perhaps a plugin for the open-source Firefox browser instead of IE?If there is in fact no current plan or desire for a more open grant application system, would you please direct me as to who might have some influence in changing this?
Thanks,

and here is their prompt response:
Dear Brock,
Thanks you for your recent inquiry to Grants.gov concerning the Pure Edge viewer.
Grants.gov has been working with Pure Edge to offer a viewer that is compatible with as many operating systems as possible. We feel that we are not too far from achieving that goal, and when we do, we will be sure that information will be posted on our website. In the meantime, we apologize if the viewer options we offer for your operating system are not acceptable. Our goal is to ensure the widest possible acceptance of Grants.gov and certainly not to exclude anyone from the electronic grants submission process. To that end, as a first step, we ensured that the Pure Edge viewer will work with a Windows emulator program, as described on our website.
Grants.gov employs the PureEdge Viewer 6.0 for viewing and completing application forms. The PureEdge viewer’s 508 compliance is described at http://www.pureedge.com/products/products/PureEdgeAccessibilityGuide.pdf. Grants.gov sponsored testing of the PureEdge viewer demonstrating the viewer’s compatibility with the widely used Jaws screen reader. An enhanced version of the PureEdge Viewer that will include compatibility with a broader range of screen reader products through support for industry standard interfaces for accessibility is in the process of being tested and upon successful completion of testing will be posted to the site.
Feel free to contact us should you have further inquiries.
Thank you,
Ryan

Encoding Movies for the iPod Video using Linux
If you want to encode video that you have on DVD for your iPod Video, a nice utility called HandBrake will do it for you. It works pretty well on Mac OS X, but my laptop’s a little slow in the I/O department, and I prefer to use my Linux desktop for encoding.
Caveat: it’s illegal to rip commercial, encrypted DVDs to your computer. Non-encrypted DVDs for which you have copyright permission, for example your home videos, are legal to rip. Don’t say I didn’t warn you.
Now that that’s out of the way, here’s a little script I wrote to rip DVDs using HandBrake for linux:
#!/bin/bash
# Filename is dvd2ipod
# $1 - output filename
# $2 - title number
handbrake -f mp4 -i /dev/dvdrw \
-o $1 -t $2 -e ffmpeg -E faac -w 320
It assumes that you’ve installed HandBrake, and renamed HBTest to ‘handbrake’ and put it somewhere in your path. It also assumes that your DVD drive is /dev/dvdrw. This outputs video in a format that iTunes will let you import, and subsequently play on your iPod Video. I didn’t set anything for audio tracks, subtitles, etc. It uses the defaults. You can easily modify this script for that. The important things are the dimensions ( -w 320 ) and the codecs ( -e ffmpeg, -f mp4, -E faac ). The first argument is the output filename you want, and the second is the title number that you want from the DVD. Say you have a DVD from your wedding with two titles — the wedding, and the reception. If the wedding is title 1, and the reception is title 2, to rip the reception, you’d do this:
dvd2ipod OurWeddingReception.mp4 2
Wait a bit, ignore the error messages as long as it keeps encoding, and enjoy showing your friends/family/coworkers your reception (or whatever)!
ADDENDUM 2007-02-07: You can now use larger movie sizes, up to 640×480, so you may want to change that if you plan on playing to an external display device. Otherwise, stick with what’s written above, as the 5G video ipod only has a QVGA screen.
Ready to Crunch
I found (in my backups — I’m so thankful that I ran nightly backups to a removable drive) a statically-linked binary of the latest version of our simulation software.
I’m now setting up a universal operating environment, containing binaries, libraries, and scripts, that I can synchronize onto the various clusters that the lab has been given access to. I think I’ll have simulations running by tomorrow around lunch time.
I’ve also started logging the time I spend on lab-type work on a daily basis. I hope this will give me more insight into how I am spending my time, so as to encourage me to make the best use of work-time that I can.
Yesterday, I did nearly seven hours of work, while today I’m probably closer to three or four. I had to run errands, including returning the multifunction printer/scanner/etc device I bought last week. The scanner doesn’t work under OS X version 10.4, contrary to HP’s claims. It was therefore taking up space and a place in my budget and it had to go. I had my eye on a replacement device, but unfortunately Best Buy did not have it in stock — only available on their website. The joys of not having a permanent mailing address.
I should be returning to Mandeville soon, and will acquire the supplies I need at that time.
