San Francisco Day-Trip Recap

The day-trip represented one of my favorites to-date: Muir Woods, Ghirardelli Square, Cable Cars, Chinatown, Golden Gate Park, Coit Tower, and Pier 39 at Fisherman's Wharf.
  1. We left Sacramento at 6:30AM
  2. Muir Woods allowed everyone in without charge on Saturday in recognition of National Public Lands Day. Dawn purchased a Muir Woods patch. 2008 represents the 100th anniversary of the founding of the monument. Arrived at 8:30AM and found ample parking adjacent to the main entrance. We trailed a few people at the start of the loop walk but by Bridge 1 had the trail to ourselves. Silence dominates the early morning in Muir Woods--no animal noises, no people noises, only the sight of the towering trees and the sound of branches shifting in the wind, the trickling flow of water in the nearby riverbed, and the crunch of one's footsteps on the dirt trail. The return trip took us over Bridge 4 and back along the Hillside Trail. Exiting the parking lot around 10:00AM, we noticed streams of cars passing the entrance--the rangers had cordoned off the entrance to our parking lot, directing traffic to the nearby secondary and overflow lots.
  3. Golden Gate Bridge greeted us with full sun and no fog. We crossed, paid the $6 toll and arrived at Fisherman's Wharf at 10:35AM. Leaving the car in the Beach & Hyde Parking Garage ($25/day maximum), we walked about two blocks to Ghirardelli Square and ate a lunch of packed sandwiches (muenster cheese, mixed greens, and spicy mustard on sourdough bread) and Thomas Kemper cane-sugar root beer next to Andrea's Fountain. Dessert consisted of a Warm Brownie Sundae at the Ghirardelli Chocolate and Ice Cream Shop.
  4. Cable Car crowds already encircled the Powell-Hyde line's turntable in Aquatic Park by 11:00AM. Instead of waiting in line, we purchased two $11 one-day unlimited municipal transportation Passports and walked north on Hyde to North Point Street and waited at the cable-car stop. Why do people wait in line? We rode the car up Russian and Nob Hills, exiting at Washington and Mason.
  5. Chinatown greeted us around 11:20AM. From Washington, we walked to Grant and proceeded south. Dawn remarked, "It's like Good Orient in person." At the Peking Bazaar, we discovered the Blue Moon Japanese dinnerware set we had drooled over online. Prices online seem competitive (ignoring S&H), especially for sets of plates. Starbucks provided a bathroom break. Dawn found a gorgeous, $150 coat from Old Shanghai (this company distributes fashions to several stores on Grant Street, including Peking Bazaar, Old Shanghai, and Canton Bazaar)--they don't seem to offer the full selection online.
  6. Union Square lay just north of our bus stop--#21 line to Golden Gate Park to see the opening day (re-opening, as it turns out) of the California Academy of Sciences building. En route, a fellow passenger informed us that by 8AM that morning, the Academy had already handed out all the free passes for the day. Lines stretching for one-half mile attested to the huge demand for the all-day free event--even at our arrival at 3PM. We walked around the many vendor booths in front of the Academy, then walked to the de Young Art Museum. Dawn noticed the cutest gopher as we walked--it's face appeared in a two-inch hole in the ground, munched grasses, then disappeared into the hole. A small crowd gathered as we watched. After several minutes, the gopher retreated and backfilled the hole with dirt, leaving no trace save the missing grass. The Japanese Tea Garden offered a peaceful respite from the many people, but Dawn decided to press on to the Museum. When we arrived, we noticed the line and decided against waiting. A late afternoon snack consisted of nuts, pretzels, gala apples, water, and a Z-Bar.
  7. Coit Tower turned out to represent the next destination. Hopping back on the #21 bus, we traveled back toward Union Square. Unfortunately, due to the heavy traffic from the Academy opening, it dumped us halfway to maintain schedule, leaving us to walk the remaining distance. Arriving at the turntable for the Powell-Hyde and Powell-Mason cable car lines, we again skipped the lines (why do people wait?) and walked north on Powell several blocks until we reached the first cable car stop. We failed to act fast enough to get on the first car, but successfully boarded the second. The car carried us a significant distance uphill and we exited at Washington, walking the remaining distance to Coit Tower on foot. Tickets cost $5/each, and the 21-story view at the top at sunset included the entire bay and city.
  8. Pier 39 represented the final destination around 6:30PM--seals, a bathroom break at the public restrooms, and Na Hoku Hawaiian Jewelry represented the final stops of the day.
  9. IHOP on Lombard at Pierce provided a dinner of pumpkin pancakes, apple juice, and hash browns as we drove out of town. Fog streamed violently over the Golden Gate Bridge as we exited the area. Arriving home at 10:30PM, we both felt happy to rest after a long day of playing tourists.
Thoughts for next time (not necessarily on the same day):
  1. Japantown--the saleswoman at Na Hoku recommended checking it out
  2. Chinatown--tableware, clothing, and so forth
  3. California Academy of Sciences in several months when the crowds become less insane
  4. San Francisco Zoo
  5. Alcatraz
  6. Mount Tamalpais sunset
  7. Japanese Tea Garden
  8. Muir Woods hiking trails
  9. Hang on outside of cable cars
  10. Wild parrots of Telegraph Hill--Coit Tower operator mentioned they frequent the hill most often between 6AM--10AM.
Total cost: ~$150, of which 33%--$20 (gas) + $25 (parking) + $6 (toll)--related to car expense and another $22 (one-day Passports) related to public transportation expense, for a total of ~50% of transportation. The evening IHOP meal cost $27, so that represents ~20% of the expense. The remaining 30% includes: Ghirardelli Warm Sundae Brownie ($9), Muir Woods patch ($5), tea strainer ($4), slice of Starbucks Pumpkin Loaf bread ($2), Coit Tower ($10), and a hoodie ($22). I'm probably missing something but that's the majority.

San Francisco Saturday Day-Trip Itinerary

Getting out of Sacramento and going to The City:
  1. 6AM--7:55AM Depart Sacramento and travel to San Francisco by car.
  2. 8AM--9:30AM Muir Woods--$5/adult. Open 8AM--~6PM in mid-September.
  3. 10:05AM--10:30PM Fisherman's Wharf--park, walk to Ghiradelli Square and eat packed mid-morning snacks. Ghiradelli Chocolates?
  4. Walk to adjacent Beach & Hyde Streets to buy SF municipal transit day passes (Passports)--$11/each, only accepts cash.
  5. Cable car (Powell-Hyde Line) to Chinatown (Washington & Mason, then walk down a few blocks to get to Chinatown proper around Grant Avenue).
  6. 11AM--12:30PM Walk through historic Chinatown
  7. Walk south from Union Square to Market & Powell and take #21 bus to 55 Music Concourse Drive in Golden Gate Park.
  8. 1:30PM--5PM Attend opening day of California Academy of Sciences (free). Prior to going in, eat packed lunches.
  9. Eat late-afternoon snacks. Take #21 bus, then F light rail to Fisherman's Wharf.
  10. 6:30PM--8:30PM trip home. Eat on the way home (IHOP?) or when we arrive home.
  • Will this itinerary survive first contact with reality? I think so--I've performed around a half-dozen guided tours of San Francisco. Potential problems--cable car lines and opening day crush of people at the California Academy of Sciences.
  • Need to get cash before we go--$18 for Muni Passports, $10 tolls (Golden Gate Bridge, Carquinez Straits)--around $40 should do it.
Things to bring:
  • Camera
  • Water bottles
  • Food
  • Map
  • Layered clothing (can get chilly by the ocean)
  • Comfortable shoes
  • Contact lens case and solution
  • Cash
  • Backpack for carrying any purchases
  • Sunscreen
  • Sunglasses

Contact Lenses

I have purchased my first pair of contact lenses since I underwent LASIK surgery in September 2003. The prescription represents a very minor correction--much better than the awful nearsightedness I had five years ago. The minor correction needed in my right eye caused strain over the course of a day staring at a computer screen, causing sickness several times over the course of the past few months. Happily, I don't need correction to drive or perform any daily tasks, so I can wear them when I work, and ignore them when I don't.

Linoleum

Removing it to expose hardwood floors represents a major investment in time. The local hardware store attendant asked me the color of the glue under the linoleum, and I responded "black"--she paused and breathed, "Oh". Not a good sign.

Happily, our next-door neighbor and a handyman and his daughter from the apartment complex near-by chipped-in, and the atmosphere felt light. He returned the next morning and finished the job--removing the tiles seems to inspire compulsion to complete the task.

The man responsible for sanding and sealing the floors arrived today (Friday) and began sanding away the glue, but it turns out the glue gets the last laugh--it completely gummed up his sander, and so he ended up spending the day scraping the glue from the boards anyway. He returns tomorrow to sand again. It will look fantastic when he finishes.

Radio Songs

Heard in the past week or two:

Venice, California-based Suicidal Tendencies' "Join the Army" from their 1987 album "Join the Army" on the Caroline label. Audio. The second half picks up a bit--I swear I heard a cover of this song.

Montreal, Quebec-based The Arcade Fire's "Rebellion (Lies)" from their 2004 album Funeral on the Merge label. Video.

Manchester, England-based Oasis' "The Shock of the Lightning" from their forthcoming 2008 album "Dig Out Your Soul" on the Big Brother label. Video. This song teaches people "Love is a time machine" which makes it all right--physics for the masses.

Downgrading Windows Vista to XP

A laptop purchase made in 2007 appears to have contained a pirated version of Windows Vista. Happily, Dawn purchased a copy of Windows XP last year through her community college for $25.

Downgrading took a bit of effort. We used David Karp's advice (http://www.pcmag.com/print_article2/0,1217,a%253D226950,00.asp) to reset the Administrator password and fix the master boot record. XP's recovery console didn't recognize the Vista Administrator password though--to fix this we used ElderGeeks' advice on how to edit the registry to bypass the setting (http://www.computing.net/answers/windows-xp/admin-password-in-recovery-console/156682.html).

Windows is dead, long live Windows.

Posting this from my KUbuntu install.

Monday Development Log

Monday:
  1. ToString() goals: 1) Implement call signature "sprintf(stdout, "%s\n", a_class.ToString());" 2) Deallocate returned char * within the object implementing ToString()--the caller doesn't have to worry about deallocating the returned char *. 3) Reduce memory bloat and handle arbitrary string lengths. 4) No streams (Google prohibits C++ streams (except for logging)). 5) If possible, avoid declaring extra class member variables.
  2. There ain't no such thing as a free lunch in C++, however. Deallocation occurs two ways--first, when variables declared on the stack go out-of-scope; and second, when variables declared on the heap get freed. The callee, in this case, deallocates the memory. The callee can deallocate the memory in these ways: 1) new within ToString(), delete within the object destructor, 2) statically declare within ToString(), deallocate at end of run-time, and 3) automatically declare within ToString(), deallocate when variable goes out-of-scope. The last choice fails because automatic allocations get reclaimed on the stack immediately when the callee returns. The first choice requires maintenance of a pointer to the new'd memory. The second choice requires a compile-time allocation of memory.
  3. Of the options, the first choice allows unlimited flexibility at the cost of additional overhead, while the second choice eliminates the overhead but requires a compile-time allocation of memory.
  4. Estonian Arvo Pärt's "Spiegel im spiegel", from his album Alina. "Spiegel im spiegel" (from Wikipedia): "can mean both "mirror in the mirror" as well as "mirrors in the mirror", referring to the infinity of images produced by parallel plane mirrors."

Sunday Development Log

Sunday:
  1. Neat: http://www.google.com/codesearch
  2. SymbolStorage maps Word Tokens to Identifiers.
  3. Flex maps strings to Word Tokens.
  4. Bison parses Word Tokens using a LALR engine.
  5. A way to convert "a_class.ToString().c_str()" to "a_class.ToString()" for use in sprintf()--statically allocate a fixed character buffer within ToString() and return a pointer to it. No memory management, no extra class member variables, no repeat allocation. The only catch--this technique only works for predictable string lengths. For example, sprintf()'ing an integer into a string--2^64 fits into a null-terminated string of 21 bytes.

    Unrestricted string lengths necessitate dynamic memory allocation.

    Google prohibits C++ streams (except for logging), which seems to rule out std::string--I haven't seen or thought of a way other than std::ostringstream.

Saturday, August 23, 2008

Sunday Development Log

Sunday:
  1. Jia Peng Fang's "Winter River"
  2. Began implementation of classes Expression, Node, and Identifier.
  3. object.ToString().c_str() it is--failed to find a clean way to implement ToString() without new/malloc.

Monday, August 18, 2008

Monday Development Log

Monday:
  1. C++ introduced references in 1983 (C lacks references--instead, C uses pointers to implement pass-by-reference).
  2. Compiling class SymbolStorage--on Tuesday I'll begin testing it thoroughly.
  3. const_cast removes or adds the const label to a variable.

Sunday, August 17, 2008

Sunday Development

Sunday:
  1. Google's C++ style guide demands fprintf() over streams. Current inconsistency results in code like this: (*a_sibling_iterator).first->ToString().c_str()--Token.ToString() returns std::string.
  2. Kasper Peeters' Tree(std::pair) might work as a syntax tree container class, but as a symbol storage container it fails to offer key-based retrieval through std::find(), even if nodes contain container std::pair. On a secondary note, it also seems to fail to support equality functor assignment at the time of declaration.
  3. Researching the Standard Template Library's Associative Containers for alternatives--std::map tests out acceptably.
  4. Schwarz Stein's "Rise To Heaven" from their album "New Vogue Children"

Saturday, August 16, 2008

Saturday Development

Saturday, picking up after six days off:
  1. Implementing class SymbolStorage with Kasper Peeters' Tree project.
  2. Researched Standard Template Library class (STL) std::pair (/usr/include/c++/4.2.3/bits/string) to hold Token/Identifier pairs.
  3. Installed VIM
  4. Annihilator's "Crystal Ann" from the album "Double Live Annihilation"

Sunday, August 10, 2008

Sunday Development Log

Sunday:
  1. Reviewed the Google C++ Style Guide for formatting, naming, and comment considerations.
  2. Adiemus' "Adiemus" from their album "Songs of Sanctuary"
  3. Installed Valgrind suite of profiling and debugging.
  4. Installed kcachegrind which provides "visual support for the cachegrind skin of the memory analyzer Valgrind."
  5. Ludovico Einaudi's "Passagio" from his album "Le Onde"
  6. Implemented ToString() using std::ostringstream code from http://bytes.com/forum/thread62153.html
  7. Very cool: this mimics Java's "public final static" class feature: "newl_parser::parser::token::NUMBER". Namespace "newl_parser" contains class "parser" which contains public struct "token", the public struct containing enumerated type "yyTokenType" which (finally) contains all token types (for example, NUMBER, IDENTIFIER, ASSIGN).

Saturday, August 09, 2008

Saturday Development Log

Saturday:
  1. inifile-->newl_parser
  2. inifileLexer-->newl_lexer
  3. inifile_driver-->newl_driver
  4. nm views symbols of object files
  5. To remedy error "multiple definition of `yyFlexLexer::yywrap()'", remove option %noyywrap--then manually redefine "int yyFlexLexer::yywrap() { return 1; }" in file lexer.ll. Flex defines yyFlexLexer::yywrap() in both %.cc and %.hh--the linker encounters multiple declarations if two objects (lexer.o and driver.o, for example, if driver.cc includes lexer.hh).
  6. Bond's "Duel" from the album "Born"
  7. Arvo Pärt's "An den Wassern zu Babel", from the album "Arbos"
  8. Yann Tiersen's "Le Moulin" from the album "Le Fabuleux Destin d'Amelie Poulain"
  9. parse() handles both char * (filename) and std::istream (stdin) depending on the signature of the call.
  10. Max Richter's "Sarajevo" from his album "Memoryhouse"
  11. Completed fully object-oriented Flex+Bison simple calculator.

Friday Development

Friday:
  1. Implementing Jan's suggested Bison/Flex C++ implementation that I discovered last night. Download example.tar.gz failed to contain files referenced by the Makefile: validate.cc, update-individual-policy.cc, combine-multiple-policies.cc. Commented-out references to them (targets "validate", "update-individual-policy", "combine-multiple-policies", "validate.o", "update-individual-policy.o", and "combine-multiple-policies.o") and modified target all to read "all: scanner.o inifile.o parser.o dump.o". I also commented out "COPTS= -m64 -mcpu=ultrasparc". It compiles.
  2. Why don't GNU projects Bison and Flex figure out how to get compatible on C++ object implementation? It's really awful, in my opinion--it could be so much better.
  3. Eluvium's "After Nature" from their album "Copia"
  4. Ludovico Einaudi's "Primavera" from their album "Divenire."
  5. Pachobel's Canon in WTF

Sunday Development Log

Sunday:
  1. Finished reading the white paper "Recursive Make Considered Harmful"
  2. Consulted the Flex manual: http://flex.sourceforge.net/manual/
  3. Compiled small Flex program in anticipation of testing new non-recursive make harness.
  4. Discovered O'Reilly's online book "Managing Projects with GNU Make Managing Projects with GNU Make, Third Edition" at http://oreilly.com/catalog/9780596006105/book/index.csp , part of their Open Book Project.
  5. It seems the nonrecursive harness uses implicit compiles for all the C files it encounters.
  6. Getting my head wrapped around the targets and dependencies of the nonrecursive make harness.
  7. Successfully modified the nonrecursive make harness so it compiles GNU Flex code into a binary.
Compiling Bison into a binary using the nonrecursive make harness represents the next step.

With all this talk about nonrecursive make, one might get the wrong impression that I'm doing this solely to learn about it. In fact, I'm finishing up a summer project for my CSC-251 compiler class, which is why GNU Flex/Bison come into play.

  4. Configured Konsole colors, font
  5. Added directory test and source file test/full-test.n.
  6. Added Makefile stubs in trunk using white-paper "Recursive Make Considered Harmful" (http://www.xs4all.nl/~evbergen/nonrecursive-make.html) as a guide.
  7. Installed Adobe Flash: sudo apt-get install flashplugin-nonfree
  8. Installed Amarok: sudo apt-get install amarok

Deleted My Task Manager

Playing with KUbuntu and I accidentally deleted my task manager. All the icons on the widget bar's task manager went away, and all the other widgets flowed left.

I re-added the task manager widget but it appeared on the extreme right, and there doesn't seem to be an easy way to rearrange them. :(

The solution: remove everything, then re-add every widget in the correct order.

A stiff penalty for an easy mistake.

Linux PDF Issues

Firefox failed to load a PDF I typed into the address bar.

After a bit of trial and error, I discovered the PDF Download add-on, which makes it all simpler when one clicks a link.

I first downloaded FoxIt PDF reader for Linux (binary) and told Firefox to use that to open PDFs. Unfortunately, it opens the ReaderLinux binary, not the PDF. And once I associated the file type with the binary, the Linux Firefox fails to provide an easy way to disassociate itself from that.

The solution: edit file ~/.mozilla/firefox/profile.default/mimeTypes.rdf, and delete the XML sections dealing with ReaderLinux. Restart Firefox. The next time you attempt to open a PDF, Firefox will prompt the user again for what to do.

The final solution? Associating Okular (/usr/lib/kde4/bin/okular) with PDF file types instead works great. And PDF Download add-on works great too.

Late Night Subversion

Recording for future use:
  1. Create a Subversion repository: ubuntu:~/src/csc-251$ svnadmin create ///home/user/.subversion-repository
  2. Import the initial file hierarchy: ubuntu:~/src/csc-251$ svn import newlc file:///home/user/.subversion-repository/newlc -m "Initial import"
  3. Create a branch: ubuntu:~/src/csc-251$ svn copy file:///home/user/.subversion-repository/newlc/trunk file:///home/user/.subversion-repository/newlc/branches/my-branch
  4. Checkout the project: ubuntu:~/src/csc-251$ mkdir newlc && cd newlc && svn checkout file:///home/user/.subversion-repository/newlc/trunk && cd trunk
Most notably, these commands seem to differ:
  • ubuntu:~$ svnadmin create ///home/user/.subversion-repository
  • ubuntu:~$ svnadmin create .subversion-repository
Why? It's a horrible user experience, in my opinion.

Under The Bridge

Walking home music today: Under the Bridge by RHCP:
Sometimes I feel
Like I dont have a partner
Sometimes I feel
Like my only friend
Is the city I live in
The city of angels
Lonely as I am
Together we cry

I drive on her streets
cause shes my companion
I walk through her hills
cause she knows who I am
She sees my good deeds
And she kisses me windy
I never worry
Now that is a lie

I dont ever want to feel
Like I did that day
Take me to the place I love
Take me all the way

Its hard to believe
That theres nobody out there
Its hard to believe
That Im all alone
At least I have her love
The city she loves me
Lonely as I am
Together we cry

I dont ever want to feel
Like I did that day
Take me to the place I love
Take me all the way

Under the bridge downtown
Is where I drew some blood
Under the bridge downtown
I could not get enough
Under the bridge downtown
Forgot about my love
Under the bridge downtown
I gave my life away
It's a great urban walking song. On my way to work on Wednesday, I noticed a man taking shelter under a bridge at Watt and Longview, which triggered this song in my head. Video.

Sleep Debt

I read an article on Wednesday stating a simple experiment:
Starting on a Sunday, do not drink alcohol or caffeine; do not smoke; go to sleep about the same time every night; and get an uninterrupted seven to eight hours of sleep for the next six nights. Then, on Saturday morning, sleep in. See how long your body will let you sleep. If you sleep longer than you did during the week -- then you have a sleep debt. So you should consider getting more sleep each night to replenish that sleep debt.
It sounds easy enough so I've decided to try it out starting on Sunday.

Bike Links

KDVS 90.3 featured Jean Jackman of Davis, CA and she recommended Adventure Cycle (http://www.adv-cycling.org) as a great bicycle tour company. They offer guided tour maps, including one a TransAmerica route: http://www.adventurecycling.org/routes/transamerica.cfm.

She also recommended the Davis Bike Club (http://www.davisbikeclub.org/) as a resource.

Sacramento Badminton


Dawn and I both like badminton:
  1. CSUS badminton club: http://www.geocities.com/Colosseum/Bleachers/2418/
  2. Folsom badminton club: http://sports.groups.yahoo.com/group/folsom_badminton/
  3. UC-Davis badminton club: http://www.ucdbadminton.com/

Dr. Patricia Chen

Dr. Patricia Chen took over as Dawn's primary care physician today.

The conversation went like this:
*Dawn explains the ear pain and how she thinks it's an Effexor discontinuation symptom*

Dr. Chen: I agree with you

*Dawn chokes up with relief*
We discussed Dawn's previous treatments under her previous primary-care physician, which involved quite a few looks of shock and silent groaning from Dr. Chen. She explained several things:
  1. Effexor, especially after being taken for nine years, deposits itself into the tissues and takes quite some time to get used up. Though it has a short half-life, when very small amounts get into the tissues it takes some time (six to eight weeks) before it's used up.
  2. The ear pain represents a discontinuation symptom Dr. Chen witnessed with other patients. The solution involves going back on a low dose of Effexor to get rid of the ear pain, then gradually introduce the SSRI fluoxetine (Prozac, Ladose) for about a month. Once the body accepts the fluoxetine, gradually eliminate the Effexor, then stay on fluoxetine until the body uses up all the Effexor in the tissues. Then taper off the fluoxetine gradually enough so no problems occur (that is, no ear pain).
  3. Dr. Chen made the same mistakes as our previous primary care physician. The difference--she took the initiative to follow-up with a psychiatrist and pursued information on effective best-practice treatments for tapering off Effexor. Our previous primary-care physician seemed to have such a high workload that he failed to make (have?) time to do this legwork.
  4. Dawn began taking the lowest dose of Effexor (37.5 mg) today and already feels reduced pain in her ears.
  5. Dr. Chen said that Dawn suffers from eustachian tube dysfunction, but that dysfunction does not account for the severe pain in her ears. Typically, eustachian tube dysfunction manifests itself as reduced hearing levels, echoes of one's voice, sort of like being underwater. I didn't ask her about our uneducated norepinephrine theory.
  6. If Dawn doesn't respond, Dr. Chen's more than willing to refer us to an ear-nose-throat specialist.
  7. Dr. Chen failed to have an explanation for why Effexor produces this discontinuation syndrome symptom--we don't think many people do know why it does this.
  8. We weren't sure why having Effexor sticking around in the tissues might cause the ear pain--wouldn't having bits of it in the tissues be a good thing in the case of discontinuation? Obviously not, but we're not sure why. There's probably a simple explanation for this.
  9. Dawn will finish out the course of prednisone--it might have minor side-effects but nothing serious.
It really represented everything we hoped for from a first visit. I called just after 8AM, got an appointment for 10:45AM, got the prescription from Costco by 12:00PM and home by 1PM.

If everything goes as planned (and it seems reasonable to expect that it might) we will only have these SSRI/SNRI medications around until roughly the end of September.

I've found the human cost in extricating oneself from Effexor alarming. Dr. Chen argued Effexor works in some situations--for example, post-menopausal women. She mentioned it represents one of the most difficult anti-depressants to discontinue.

Even worse--paroxetine (Paxil), which exhibits many of the same problems as Effexor but for which Dr. Chen doesn't have a tested discontinuation plan. Since paroxetine represents an SSRI, using it in combination with fluoxetine (another SSRI) proves problematic. Dawn used Paxil for one year many years ago, then her doctor switched her to Effexor. So that represents one lucky break.

In my opinion, doctors exhibit reckless behavior by putting patients on SSRI/SNRI class medications without extensive knowledge of discontinuation effects and how to successfully manage them. Dr. Chen learned the hard way--doctors like our previous primary care physician of two years still don't know even after watching a patient like Dawn endure three exceedingly painful attempts at discontinuation.

Even more alarming--Dawn's far from alone. Google returns 424,000 hits for "effexor withdrawal". A sharp contrast exists between horror stories on the Internet and the level of awareness in the four out of five doctors we interacted over the last three months.

Eustachian Tube Dysfunction



Dawn's suffering from eustachian tube dysfunction right now. It's an awfully painful condition where the middle ear fills up because the eustacian tube closes due to inflammation (see above image).

A healthy eustachian tube (named for Eustachius) opens to equalize pressure in the middle ear. That popping feeling when you gain or lose altitude? That's the eustachian tube opening to equalize pressure in your ear. See this EarDoc advertisement for an explanation of what happens: http://youtube.com/watch?v=XdqrGaUF5EQ (I love the duck).

Dawn tapered off of the anti-depressant Effexor on Wednesday, July 16th and began experiencing symptoms on Thursday, July 17th, with the pain gradually increasing in severity. Dawn experiences the ear pressure pain each time she tapers off Effexor, this being the third time. It's not listed as a common side-effect on the Effexor patient information leaflet. Since she's experiencing considerable, chronic pain, we visited her primary care physician on Friday, July 25. He assured her there's no danger of rupturing of the eardrum and noticed a bulge in her right eardrum (where most of the pain occurs).

Since we don't have a good track record with her primary care physician, we're switching doctors immediately to a highly-rated female doctor closer to home, Dr. Patricia Chen. On Saturday, July 26, we visited Med7 and got another opinion. He prescribed prednisone, a steroidal decongestant, and recommended seeing an ear-nose-throat specialist if it didn't work.

Well, it's not really working, two days in--though seven days remain, the bulk of the prednisone is taken in the first three days. So, we're guessing that we'll have to see an ENT specialist as soon as we can.

Our latest theory here takes into consideration the fact that Effexor acts as an SNRI (seratonin-norepinephrin reuptake inhibitor) boosting the levels of norepinephrin in the body.

Since pseudo-epinephrine aids in reducing swelling, we theorize that increased levels of norepinephrine (adrenaline, basically) possibly aided with reduction of swelling in Dawn's ears (caused by allergies, most likely, the Central Valley being the allergy capital of the world), thus keeping the eustachian tubes open and draining/equalizing the pressure in her middle ear. This theory has the support of some empirical evidence--each time Dawn goes back on Effexor (even temporarily) the pain diminishes immediately. Dawn's a bit skeptical, since she felt even worse pain when she tapered the first time--she thinks it might be a possible side-effect.

We guess that once the boosted levels of norepinephrin disappear (as Dawn ceases taking the SNRI), the swelling increases, shutting the eustachian tubes, filling the middle ear with fluid and causing the painful pressure on the eardrum.

Thoughts? I'm pretty ignorant in this area but have been reading as much as I can. We may be completely off-base. The doctors we've talked to have no clue about the correlation between Effexor discontinuation and the ear pain though, so perhaps our opinions make at least a bit of sense.

If worse comes to worse, an ENT can perform a myringotomy--but obviously we're hoping it doesn't have to go that far. There seem to be some devices on the market (like the EarDoc, http://eardoc.info, and the EarPopper) but they're expensive and we're skeptical without knowing more. On Monday we make an appointment (hopefully for as soon as possible) with Dr. Chen. We're hoping that we can get an immediate referral to see an ENT specialist ASAP.

Verbal words to review:
  1. Spate: a sudden, almost overwhelming, outpouring: a spate of angry words.
  2. Provident: having or showing foresight; providing carefully for the future.
  3. Credulity: willingness to believe or trust too readily, esp. without proper or adequate evidence; gullibility.
  4. Boon: something to be thankful for; blessing; benefit.
  5. Inexorable: unyielding; unalterable: inexorable truth; inexorable justice.
  6. Confounding: To cause to become confused or perplexed
  7. Appropriate: to set apart, authorize, or legislate for some specific purpose or use
  8. Profligate: utterly and shamelessly immoral or dissipated; thoroughly dissolute.
  9. Myopic: unable or unwilling to act prudently; shortsighted.
  10. Rueful: feeling, showing, or expressing sorrow or pity; mournful; doleful: the rueful look on her face.
  11. Antithetical: directly opposed or contrasted; opposite.

  16. Opportune: appropriate, favorable, or suitable: an opportune phrase for the occasion.
  17. Convenience: anything that saves or simplifies work, adds to one's ease or comfort, etc., as an appliance, utensil, or the like.
  18. Whet: to sharpen (a knife, tool, etc.) by grinding or friction.
Quantitative areas to review/improve upon:
  1. Ratios and recognizing trick questions regarding graphs
  2. If the initial answer seems obvious, it probably warrants additional attention. For example, x^2 is larger than x^3 with the constraint that 5x fall between 0 and 3.
  3. Systems of equations
  4. Double-check answers close to other possible choices.
  5. Trig review
The computer adaptive test doesn't allow calculators, only scratch paper. No reviewing of questions.

I've met my goal on the verbal (600, 85th percentile), but meeting the goal on the quantitative (750, 85th percentile) will take effort.

Symbol Table Compiled

Tonight I successfully compiled the bare-bones symbol table. The symbol table of a compiler maps high-level words (tokens) in the source language to internal symbols.

I thought I compiled a test harness using the STL map last night but in reality I used std::map. g++ reports cryptic compile conflicts between the downloaded STL and std::map that seem like a namespace conflict. If I have time I plan to investigate--right now std::map meets my modest needs.

One more RHCP song to close out the night: http://youtube.com/watch?v=yuFI5KSPAt4

Waialua Root Beer


Image credit: Flickr

Waialua root beer represents the latest root beer tasting. I found the smooth vanilla reminding me of cream soda. The Waialua Soda Works company also produces a Vanilla Cream Soda, so perhaps the root beer represents a foreshadowing of that beverage.

Worth a taste; personal preference will dictate whether to try a second buy--I didn't find the creaminess attractive enough for a repeat.

We hope to review more traditional root beers (read: non-high fructose corn syrup-based root beers) in the future, maybe one every week or so.

Second Grad School Hurdle, or, There's a Light At the End of the Tunnel

It turns out my undergrad computer science GPA in the CSUS core course equivalents doesn't reach the magic number of 3.25 that's needed to enroll in the grad school program and take the core grad school courses. So, this fall and next spring, I plan to take CSc 137, "Computer Organization" and CSc 130, "Data Structures and Algorithm Analysis," respectively, to get there.

This bumps my targeted grad school enrollment date out to Fall 2009--I'll get there, and I'll be stronger for it.

I think I have all the bugs worked out of the enrollment process now, and am feeling confident about the plan going forward. Dr. Cui Zhang, CSUS graduate coordinator, has helped a lot with the questions I've had.

It's All About the Benjamins

As a graduate student, I can expect to pay $1,383.00 for up to six credits of class-work per semester.

As an Open University student, I can expect to pay $480 for one three-credit class ($160/unit).

However, I can only take one more class as an Open University student and expect to apply it to my graduate degree, as they cap the number of credits at six. Thankfully, CSc 201 represents a three-unit class.

Hiccup in Graduate Planning

I met with Dr. Cui Zhang at CSUS on Monday afternoon and together we dusted off my transcript from the University of Wisconsin-Eau Claire. Dr. Zhang informed me that the CSUS Computer Science graduate program requires students to take a course in Computer Organization (CSc 137 or equivalent)--one of the few classes I did not take during my undergraduate career. She encouraged me to continue preparations for the October 1st application deadline, with the expectation of admission as a conditionally classified student.

This evening, I discovered that CSUS offers CSc 137 this fall, but it conflicts with normal business hours: Dr. Faroughi teaches it every Tuesday/Thursday from 9:00 AM--1:00 PM (class from 9:00 AM--10:15 AM, then lab from 10:30 AM--1:00 PM). So, I'll have to discuss the possibility of accomodating this class with my employer.

The Los Rios Community College District offers an equivalent, transferable course, CISP 315, "Introduction to Computer Architecture and Design," but only in the spring.

Dr. Zhang recommended taking up to two core graduate-level classes this fall (she shared most students take two out of financial efficiency):
  1. CSc 201: "Programming Language Principles" (C. Zhang, M/W, 5:30--6:45 PM)
  2. CSc 204: "Data Models for Database Management Systems" (B. Mitchell, T/Th, 4:00--5:15 PM)
  3. CSc 205: "Computer Systems Structure" (B. Arad, T/Th, 5:30--6:45 PM)
  4. CSc 206: "Algorithms and Paradigms" (C. Wang, M/W, 4:00--5:15 PM)
  5. CSc 209: "Research Methodology" (C. Zhang, T, 7:00--7:50 PM)
From an e-mail Dr. Zhang sent out on May 7, it seems waivers do exist:
csc204 and csc205 Waiver Tests
==============================
For those of you who wish to get the core course csc204 and/or
csc205 waived, there are once/semester waiver tests for you
scheduled each semester about one week before school starts.
For Fall 2008, the two tests will be given on Monday Aug. 25,
2008 at noon in RVR-2018. Please mark your calendar if you wish
to waive csc204 and/or csc205 and I'll see you on Aug.25 at noon.

University Professor Web Pages

This evening I browsed through the personal web sites of full-time faculty at the California State University at Sacramento (CSUS) and the University of California at Davis (UC-Davis).

As a first impression, the personal faculty web sites at both campuses scared the hell out of me.

The winners of best web sites, in my opinion:
Notables:
Profs that care:
Fun:
Oddities:
What I liked: professional picture, clean layouts, pictures of the instructor with students

A point of irony: the CSUS department's 2006-2007 assessment report lists "Communication skills and interpersonal skills" as an essential skill on page two.

A second point of irony: UC-Davis has six people (other than Dr. Staadt and Dr. Ma) whose stated interests involve computer graphics, animation, or visualization: 1, 2, 3, 4, 5, 6--yet their web sites remain woefully primitive, in my opinion.

The serious takeaway: It's all-too-easy to mock people's weaknesses, and I hope this attempt at humor comes across as just that--these people are probably all outstanding in their fields (no pun intended), great people, and great instructors. Yet, if faculty fail to communicate clearly using the most widely available medium available to them, how can we inspire students to do so? This isn't a new phenomenon--the CS faculty web pages of my alma-mater haven't improved that much since I graduated in 2000 (even the resident computer animation expert).

CSUS Grad Courses Fall 2008

As a student taking graduate-level classes through the CSUS Open University program, I have these class options to choose from for Fall 2008 (assuming I can waive the prerequisite CSC 205 course--which requires fully classified status to take):
  1. CSC 239 (Chang W.). Advanced Operating Systems Principles and Design. (AVAILABLE FALL 2008; PRE: CSC-205)
  2. CSC 242 (Arad B.). Computer-Aided Systems Design and Verification. (AVAILABLE FALL 2008; PRE: CSC-205)
  3. CSC 255 (Ghansah I.). Computer Networks. (AVAILABLE FALL 2008; PRE: CSC-138)
  4. CSC 273 (Arad B.). Hierarchical Digital Design Methodology. (AVAILABLE FALL 2008; PRE: CSC-205)
The other graduate-level classes offered:
  1. CSC 201. Programming Language Principles.
  2. CSC 204. Data Models for Database Management Systems.
  3. CSC 205. Computer Systems Structure.
  4. CSC 206. Algorithms and Paradigms
  5. CSC 209. Research Methodology
  6. CSC 233. Advanced Software Engineering Project Management.
  7. CSC 234. Software Verification and Validation.
  8. CSC 235. Software Architecture.
  9. CSC 252. Cryptography Theory and Practice.
  10. CSC 254. Network Security.
  11. CSC 280. Advanced Computer Architecture.
require fully-classified graduate level status. CSUS might offer waivers--I'm not sure yet.

Two other classes that seem interesting:
  1. CSC 133. Computer Graphics
  2. CSC 165. Computer Game Architecture
On Rate My Professors, W. Chang he gets a 2.1--but only from undergrad-courses. The web site fails to list any other professors. Helpfully, his web site shows a Mac icon beating down a Windows icon. The web site fails to list anything about Arad or Ghansah.

PickAProf.com rocks--it lists the grades given by a prof. It doesn't seem as popular though, in terms of reviews, even though it started in 2000.

Teacher Ratings

How awful (I laughed, I cried):
"My will to study computer science has been completely destroyed."
This evening I'm reviewing CSUS prof ratings and deciding which class to take for the fall semester--this comment popped out.

GRE

Gearing up to take the GRE before the October 1st (88 days) Sac State application deadline so I can get in for the Spring 2009 semester. Hopefully by 2011 I'll have my Masters degree.

Amby provides a slew of links: http://amby.com/GRE/.

Steps to reach my goal:
  1. Meet with CSUS department representative and discuss whether I meet all outstanding requirements
  2. Achieve GRE scores of:
    600 on the Verbal Reasoning (85th percentile)
    750 on the Quantitative Reasoning (85th percentile)
    5 on the Analytical Writing Score (96th percentile)
  3. Complete and submit paperwork
I initially put up more aggressive targets, but then I realized that I'm not going to have as much time as I want to prepare for the GRE. The CS grad program at CSUS seems to use the GRE as a comparison benchmark against other applicants for the semester--they seem to care more that applicants have the proper foundation.

My thought at this point is: test early, test often to get a sense of where I'm at.

Hikes

The attendant at Smog Busters shared several locations for hikes involving waterfalls in the Northern California area:
  1. Bassi Falls (Pollock Pines, El Dorado National Forest, El Dorado County)
  2. Feather Falls (Oroville, Feather Falls Scenic Area, Plumas National Forest, Butte County)--"Outside of Yosemite, this is maybe the best waterfall in California."
He says Spring represents the best time to hike since the water flow reaches its peak. He also recommended http://waterfallswest.com as a resource.

I asked him if he had hiked the Stevens Trail and he said no.

The Waterfalls West web site looks like a ripe place to host a wiki (ala http://wikitravel.com).

Supi Udupi

After the movie, we visited Udupi Indian Restaurant on Sunrise: http://www.vegguide.org/entry/3814. I ordered the deluxe dinner, which had a smattering of everything. Minimalistic interior, but outstanding staff and a wonderful feast.

Flight of the Red Balloon

I enjoyed the long takes of this film--some as long as eight minutes. All dialogue's improvised. So much of the movie takes place within Suzanne's (Juliette Binoche) apartment that by the end I felt very much at home there--it's a cozy, bohemian Parisian loft, with an abundance of books and scattered items. When Simon went to "have a go" on his Playstation, I wanted to know what game he played. The poster on the back of the door advertised "La Ballade de la Mister Punch", a tribute to the Punch and Judy puppet show. The movie seems as though it's from Song Fang's perspective--unjudging, attentive, thoughtful, cozy. Song adapts and becomes the calm in the middle of deteriorating relationships--Marc, the downstairs tenant, who hasn't paid rent in over a year; and Pierre, Simon and Louise's father who has abandoned his family to live in Montreal. The ending comes abruptly, amidst a teacher discussion in the Musée d’Orsay over Félix Vallotton’s 1899 painting of a child chasing a red ball, "Le Ballon." The movie fades away with the song "Tchin Tchin" (French for "cheers") by singer Camille. The movie also seems like it might document the view from Simon's perspective--adrift as he floats between school, home, the cafe where he plays pinball, and piano lessons. The home becomes a womb, but without Suzanne, it also seems somewhat empty. Suzanne comes and goes freely, in her words, "making everyone happy." The end of the film seems to document how much Simon's needs aren't getting met--Louise chooses to stay in Brussels to care for her great-grandfather, leaving Simon visibly upset (sleeping with his bear). Song, as the nanny, checks in to let him know she cares, but respects his grieving and lets him rest. Suzanne, slowly but successfully restoring order to the chaos left by Pierre's departure two years earlier, struggles to keep the threads of her family together. As I mentioned, the ending comes abruptly, leaving me wanting to see more--what happens next? The chemistry seems right for thsi family though--I suspect they turn out all right, between Suzanne's passion and Song's presence.

Even though we ate before watching this movie, I felt incredibly hungry watching it. Watching Song learn to make crepes, or Suzanne offer a biscuit, or Marc prepare vegetables, or a poured glass of wine--I couldn't wait to eat.

From left to right: ? (Chinese professor), Song Fang (Song), Louise Margolin (Louise), Juliette Binoche (Suzanne), Simon Iteanu (Simon), and Hippolyte Girardot (Marc).

Fire

The sun looked like this on the way home:


(note: not my pic, and not a pic of Sacramento)

Living in California's Central Valley means smoke from fires flows down into the "bowl" where we live from the foothills to the east, west, and north.

A few years ago, the fires produced enough ash that it looked like a light snow dusting for 24 hours.

A co-worker told me yesterday that about eight years ago, she saw the wind creating billows of smoke.

I can't smell the smoke unless I drive with the window down.

Nothing threatening or scary--a relatively minor side-effect of living in one of the safest places on earth (no hurricanes, no tsunamis, no earthquakes, minor chance of floods, no tornadoes, no snowfalls, and so forth).

5.2.2 a, b: Investigating GraphViz as a solution to presenting trees

5.2.3: Suppose that we have a production A -> BCD. Each of the four nonterminals A, B, C, and D have two attributes: s is a synthesized attribute, and i is an inherited attribute. For each of the sets of rules below, tell whether (1) the rules are consistent with an S-attributed definition (2) the rules are consistent with an L-attributed definition, and (3) whether the rules are consistent with any evaluation order at all?

a) A.s = B.i + C.s
  1. No--contains inherited attribute
  2. Yes--"From above or from the left"
  3. Yes--L-attributed so no cycles
b) A.s = B.i + C.s and D.i = A.i + B.s
  1. No--contains inherited attributes
  2. Yes--"From above or from the left"
  3. Yes--L-attributed so no cycles
c) A.s = B.s + D.s
  1. Yes--all attributes synthesized
  2. Yes--all attributes synthesized
  3. Yes--S- and L-attributed, so no cycles
d)
  • A.s = D.i
  • B.i = A.s + C.s
  • C.i = B.s
  • D.i = B.i + C.i
  1. No--contains inherited attributes
  2. No--B.i uses A.s, which depends on D.i, which depends on B.i (cycle)
  3. No--Cycle implies no topological sorts (evaluation orders) using the rules
5.2.4: This grammar generates binary numbers with a "decimal" point:
  1. S -> L . L | L
  2. L -> L B | B
  3. B -> 0 | 1
Design an L-attributed SDD to compute S.val, the decimal-number value of an input string. For example, the translation of string 101.101 should be the decimal number 5.625. Hint: use an inherited attribute L.side that tells which side of the decimal point a bit is on.
  1. S -> L . Lsubone
    1. L.inh = 0
    2. Lsubone.inh = -1
    3. S.val = L.syn + Lsubone.syn
  2. S -> L
    1. L.inh = 0
    2. S.val = L.syn
  3. L -> Lsubone B
    1. Lsubone.inh = L.inh + 1
    2. B.inh = L.inh
    3. L.syn = Lsubone.syn * B.syn
  4. L -> B
    1. L.syn = B.syn * 2^L.inh
  5. B -> 0 | 1
    1. B.syn = digit.lexval
5.2.5: Design an S-attributed SDD for the grammar and translation described in 5.2.4.
  1. S -> L . Lsubone
    1. S.val = L.lhs + Lsubone.rhs
  2. S -> L
    1. S.val = L.lhs
  3. L -> Lsubone B
    1. L.lhs = Lsubone.lhs + (2^L.lhs_exponent * B.val)
    2. L.rhs = Lsubone.rhs + (2^L.rhs_exponent * B.val)
    3. L.lhs_exponent = Lsubone.lhs_exponent + 1
    4. L.rhs_exponent = Lsubone.rhs_exponent - 1
  4. L -> B
    1. L.lhs = 2^L.lhs_exponent * B.val
    2. L.rhs = 2^L.rhs_exponent * B.val
    3. L.lhs_exponent = 0
    4. L.rhs_exponent = -1
  5. B -> 0 | 1
    1. B.val = digit.lexval

5.3.1: Below is a grammar for expressions involving operator + and integer or floating-point operands. Floating-point numbers are distinguished by having a decimal point.
  1. E -> E + T | T
  2. T -> num . num | num
a) Give an SDD to determine the type of each term T and expression E.
  1. E -> Esubone + T
    1. E.type = if (E.type == float || T.type == float) { E.type = float } else { E.type = integer }
  2. E -> T
    1. E.type = T.type
  3. T -> numsubone . numsubtwo
    1. T.type = float
  4. T -> num
    1. T.type = integer
b) Extend your SDD of (a) to translate expressions into postfix notation. Use the binary operator intToFloat to turn an integer into an equivalent float. Note: I use character ',' to separate floating point numbers in the resulting postfix notation. Also, the symbol "||" implies concatenation.
  1. E -> Esubone + T
    1. E.val = Esubone.val || ',' || T.val || '+'
  2. E -> T
    1. E.val = T.val
  3. T -> numsubone . numsubtwo
    1. T.val = numsubone.val || '.' || numsubtwo.val
  4. T -> num
    1. T.val = intToFloat(num.val)
5.3.2 Give an SDD to translate infix expressions with + and * into equivalent expressions without redundant parenthesis. For example, since both operators associate from the left, and * takes precedence over +, ((a*(b+c))*(d)) translates into a*(b+c)*d. Note: symbol "||" implies concatenation.
  1. S -> E
    1. E.iop = nil
    2. S.equation = E.equation
  2. E -> Esubone + T
    1. Esubone.iop = E.iop
    2. T.iop = E.iop
    3. E.equation = Esubone.equation || '+' || T.equation
    4. E.sop = '+'
  3. E -> T
    1. T.iop = E.iop
    2. E.equation = T.equation
    3. E.sop = T.sop
  4. T -> Tsubone * F
    1. Tsubone.iop = '*'
    2. F.iop = '*'
    3. T.equation = Tsubone.equation || '*' || F.equation
    4. T.sop = '*'
  5. T -> F
    1. F.iop = T.iop
    2. T.equation = F.equation
    3. T.sop = F.sop
  6. F -> char
    1. F.equation = char.lexval
    2. F.sop = nil
  7. F -> ( E )
    1. if (F.iop == '*' && E.sop == '+') { F.equation = '(' || E.equation || ')' } else { F.equation = E.equation }
    2. F.sop = nil
5.3.3: Give an SDD to differentiate expressions such as x * (3*x + x * x) involving the operators + and *, the variable x, and constants. Assume that no simplification occurs, so that, for example, 3*x will be translated into 3*1 + 0*x. Note: symbol "||" implies concatenation. Also, differentiation(x*y) = (x * differentiation(y) + differentiation(x) * y) and differentiation(x+y) = differentiation(x) + differentiation(y).
  1. S -> E
    1. S.d = E.d
  2. E -> T
    1. E.d = T.d
    2. E.val = T.val
  3. T -> F
    1. T.d = F.d
    2. T.val = F.val
  4. T -> Tsubone * F
    1. T.d = '(' || Tsubone.val || ") * (" || F.d || ") + (" || Tsubone.d || ") * (" || F.val || ')'
    2. T.val = Tsubone.val || '*' || F.val
  5. E -> Esubone + T
    1. E.d = '(' || Esubone.d || ") + (" || T.d || ')'
    2. E.val = Esubone.val || '+' || T.val
  6. F -> ( E )
    1. F.d = E.d
    2. F.val = '(' || E.val || ')'
  7. F -> char
    1. F.d = 1
    2. F.val = char.lexval
  8. F -> constant
    1. F.d = 0
    2. F.val = constant.lexval

Turning the Wrong Way

I thought the nut on the p-trap under our bathroom sink turned lefty-loosey but it turns out it turns righty-loosey. How easy it is to turn when one goes in the right direction.

In other news, I've determined that the ceiling fans in our duplex (A Hunter model #21416 and a KDK model #D13YU) lack a hole made for oiling. The new Hunter fan makes a rhythmic ticking noise after about a day or so of high-speed operation, while the older KDK fan makes the same rhythmic ticking noise more consistently. My first thought--oil the bearings, per: http://www.ceiling-fans-n-more.com/ceiling-fan-oiling.php. Unfortunately, the manufacturer did not intend for customers to oil these fans, so I'm going to need some creativity to do so. It might also be a balancing issue...so who knows if I'll have time to figure it out in the coming weeks.
