Yes, I do have a brain.
I took the day off yesterday to travel to Boston University to participate in a Gulf War Illness research study.
The study is looking to identify biomarkers that might indicate Gulf War Illness. It cost me a day off of work and paying for my travel expenses but I was able to add my information to the pool of data so that it might help other Gulf War veterans.
Part of yesterday’s tests included a structural MRI, after which I was sent home with a copy of my imaging data. Being a data nerd, this thrilled me and I couldn’t wait to check out what was on my CD. While the typical image tools available for Linux like GIMP were able to view the images, it wasn’t until I installed the MRIcron application that I was able to view my imagery in three dimensions. MRIcon converts the DICOM files that the MRI generated into an open format that can then be manipulated by MRIcron.
Pretty cool, although a bit disconcerting to realize I’m looking at tiny slices of my own head. There’s a strong part of me that keeps thinking “man, you’re not dead yet! You should not be seeing your brain!” Coupled with my image data, MRIcon is a really captivating tool for exploring the structure my brain (and my head as well).
Looking closely at the third image you can clearly see that my eyeballs are shaped completely differently. This probably accounts for my unusual combination of nearsightedness and farsightedness. Good times.
As most residents are now aware, a few weeks ago the city of Raleigh become one of the few lucky (?) municipalities to get rentable electric scooters. These scooters (mostly of the Bird brand at this point) have been zipping merry residents from one end of town to the other for a small fee. While many are pleased that this new mobility choice has possibly decreased the number of car trips, others have pointed to the dockless nature of the scooters and how this inevitably leads to the scooters blocking sidewalks.
The City Council has not yet weighed in on the legality of scooters making their home on the sidewalks without having first been given official permission. Thus, they are operating in kind of a gray area. I decided to look into the Raleigh Municipal Code to see what laws we have on the books regarding sidewalks and motor vehicles.
It didn’t take long to find the relevant section in the Raleigh Municipal Code (and conveniently linked to from the links page of my EastRaleigh.Org website – I am awesome). Emphasis is mine:
Sec. 11-2171. – PARKING PROHIBITED IN CERTAIN PLACES.
(a) Obstructing traffic.
It shall be unlawful for any person to stop, stand or park any motor vehicle upon a street , or alley, in such manner or under such conditions as to obstruct the free movement of vehicular traffic, except that a driver may stop temporarily during the actual unloading of passengers or when necessary to obey traffic regulations or signs or signals, or signals of a police officer .
(b) Designated places.
No person shall stop, stand or park a motor vehicle (attended or unattended) except when necessary to avoid conflict with other traffic or in compliance with the directions of a police officer or traffic-control device in any of the following places:
(1) On a sidewalk, in the area between the roadway and the sidewalk, in the area between the right-of-way line and the roadway or in the median area of a divided roadway
I’ve been reading through Adam Fisher’s Valley of Genius book and got to the chapter about The Well, one of San Francisco’s first online communities. It reminded me that I, too, was online as early as 1982, dialing up BBSes from my family’s 300-baud modem. I think the first BBS I called was run by a guy at the University of South Carolina.
Of course, a few years later in 1986 I had set up my own BBS in Great Falls, VA called the Basement BBS. At its peak it had 350 members, two high-speed (19.2 Kbps!) modems, and an early consumer hard-drive (10 whole megabytes!). Good times.
Valley also reminded me of my occasional hobby project of figuring out how to get the Basement back online here in the age of the Internet. This has proven to be more challenging than I expected, because:
1. DOS is a strange world, indeed, with lots of obscure drivers, configuration files, and confusing syntax.
2. I have forgotten 90% of the DOS secrets I once knew.
3. Modern virtualization systems were not designed with DOS virtual hosts in mind.
4. Virtualized DOS systems run far faster and with far more memory than their 80s era computers ever had, which causes problems.
Building a virtualized DOS environment is akin to assembling a ship in a bottle. You’re building a replica of an ancient artifact using very limited tools. All this, and I haven’t even gotten to the magic of modem emulation that will connect my BBS to the larger Internet.
This is the perfect geek project, though: a completely useless exercise in technology exploration. I hope, though, that at the end of it I have something to show for my trouble. But if I don’t that’s okay because I will have learned something anyway.
As usual, I’ve had a ton of irons in the fire, squeezing as much out of the waning summertime days as I can. That hasn’t left much time nor inspiration for blogging but I’m hoping to get back on track with this.
Major stuff I’ve been doing around in my free time includes replacing the falling-apart wooden steps on my back deck with composite decking. This project took two sweltering Saturdays to complete but I’m very pleased with how the steps came out. Next up is the deck surface itself which, frankly, will be easier than the steps since there’s far less cutting needed. After that I’ll have to dream up a good plan for replacing the wooden railing but I’ve got a little time to figure that out.
I hope the whole project will be done by fall. Then I’ll combine the scrap wood from my deck with the scrap fencing from my fence job and haul it all away for a clean yard again. Yay!
