WanderingThis refers to walks. I love them, since Flesherton, since the Lord of the Rings, since Vancouver and New Zealand and everywhere. It also refers to travel, again Vancouver and New Zealand, as well as Germany and Spain. I hope to travel a lot in my life, and a spend a lot of it in nature. That's a huge part of this, being able to climb mountains and run through woods and walk in rivers. I like talking when walking, so fellow adventurers are welcome.
Iaido and JodoParticularly within my club, Sei Do Kai. I love the control and interaction with the physical world around me and my body. I love the people I do it with. I love the life lessons it teaches me. I love the attitude and the philosophy of our club. I think this fills in a gap in my physical interacts with the world that wandering couldn't quite fill, and kendo could have but failed. It helps motivate me to remain fit, which requires additional exercise outside of budo.
Open Source ProgrammingI really enjoy programming. This fulfills a lot of my intellectual and creative urges that used to go towards drawing and writing. It also makes me feel good as a person, because I can contribute to a larger community and help others. I like the GNOME project in particular and its philosophy and product.
FriendsThis used to rank higher on the list, but I've tried to become more singular in the past year, much more independent. I am more cynical about others and for what they can be relied upon, which has been quite healthy. Of course, I still love my friends and value the time I get to spend with them. I go a bit less out of my way to attend to them, though, and claim more time for myself.
VeganismVeganism is the best contributor to my ethical framework and moral compass. It motivates me to be more involved in my health and more compassionate in the world around me. This complements budo, which helps encourage fitness through exercise, by encouraging me to pay more attention to my diet, which requires it. It also acts as a social platform, where I get to socialise with vegans (which is often very relaxing) and get to bring other friends together around food (someone's willingness to try my vegan cooking is a good litmus test for friendship). I'm not strongly into animal rights activism, due to disputes over methods.
Artificial IntelligenceI really like the ideas behind artificial intelligence and the future potential for it. Consequently, I'm doing my thesis in Natural Language Processing. I'm not a huge fan of academia, but am glad to have an opportunity to work with AI.
This is the point in the list where I have run out of enough time, and the interests below are neglected.
LanguagesI like language because I like meaning. Communication of meaning is one part of that interest, so I enjoy learning languages. So far I only have conversational German. I would like to know French, some Japanese, and Chinese eventually.
ViolinIt's my favourite instrument. I like the fun of fiddling and the sophistication of the string sound. I love the construction, and its portability. I own one, but due to other priorities, have been waiting to find an economical teacher to pursue this. (My iaido sensei's daughter is an experienced violinist, and may take up teaching me this summer!)
Nintendo!I loved video games growing up, and they would have typically topped a list then. I took a long hiatus during my undergraduate, and have slowly been re-entering the world. Sadly, I don't have a core friendsuite to enjoy Nintendo with any more. Most of my old friends have taken a greater interest in PlayStation or Xbox. I still haven't finished Skyward Sword despite loving the series. I hope to be able to find someone local to share games with in the future.
KendoI really loved kendo when I was in high school, but I think that the Owen Sound Kendo Club was a significant part of that. I haven't enjoyed another kendo club quite the same, excepting perhaps the UBC Kendo Club, back in Fall 2008. My history runs like this
- 2000-2003: Owen Sound Kendo Club :D
- 2003-2004: Guelph Kendo Club :|
- 2008: UBC Kendo Club :D
- 2009: Invercargill Kendo Club :|
- 2011-2012: Guelph Kendo Club :)
PianoI like the idea of playing the piano because I've enjoyed the company of pianists many times throughout my life. I enjoyed playing simple songs on it when I had a tutor, but due to distance (she was in Korea) I haven't kept up. I mostly was interested in the piano to learn some fundamentals of music before coming to the violin, though.
DrawingI used to really enjoy drawing and still like the idea of bringing fantastic worlds to life in art. However, I do not fantasise as much as I used to, so the compunction to draw is much less than it has been before. I'd like to find time to improve my drawing of people, though, and do more little sketches. I enjoy doodling and adding sketches to embellish other work, like signs and cover pages, etc. And adorning my abode with little visuals. I need to finish a story I started about viking teddy bears, but I haven't had the heart to continue on it in two years.
WritingI have two stories in particular, G21 and the story of Afawnoly, that I would like to tell at some point. I haven't felt equal to the task, and would need to do more reading and practise writing to acquire a suitable voice and taste for description.
So there you have it, a rough list of things that matter to me, with the most at the top. There are many, many other things that I am interested in, but they are generally even less of a priority. If you think something is conspicuously missing, though, let me know; maybe something important slipped my mind.
I like the new scan feature in Google Drive. I already scan a lot of documents just using my camera. Having them filed as PDFs will be much nicer.
Google+ Photos will let you search the photos themselves. If you search "tulips" now, it will find photos containing tulips, and not just wants that have tulips noted in captions. That's thrilling.
Aaron Diaz quotes Seth Godin:
The strategy is to have a practice, and what it means to have a practice is to regularly and reliably do the work in a habitual way.
The notion that I do my work here, now, like this, even when I do not feel like it, and especially when I do not feel like it, is very important. Because lots and lots of people are creative when they feel like it, but you are only going to become a professional if you do it when you don’t feel like it. And that emotional waiver is why this is your work and not your hobby.
Here are some notes on a presentation I attended yesterday. It's about fast motion in zoology, specifically looking at creatures that use elastic energy to snap at things, like Mantis Shrimp and Trap-jaw ants. It was wonderful. The notes are not too well organised, but I am happy that taking them with org-mode in emacs let me easily export them to an HTML I could pretty simply embed. :D
Sudden and Swift
Table of Contents
1 Sudden and Swift: Extreme Movements in Biology, with Sheila Patek
Dr. Sheila Patek, Zoology, University of Massachusetts Amherst, Duke University
- Mantis Shrimps
- introduced by teacher of Invertebrate Zoology
- isopod crustaceans underrepresented in his course, in favour of Mantis Shrimp
- What is fast?
- not about cheetahs or diving falcons, which are slower than MS
- fast in physics, evolutionary history
- research spectrum
- basic research (fun and satisfying, building knowledge)
- applied research
- Catalina island
- Rachel Carson, 1950, The Sea Around Us quote
- "One of the most extraordinarily widespread sounds of the undersea is the crackling, sizzling sound, like dry twigs burning or fat frying, heard near beds of the snapping shrimp... The shrimp are forever clicking the two joints of this claw together."
- snapping shrimp Alpheus heterochaelis
- Rachel Carson, 1950, The Sea Around Us quote
2 Snapping Shrimp
- in 2000, they were able to watch at 40,500 frames per second, the snapping of the shrimp, creating a cavitation bubble
- this is speed, underwater
- the sound is the cavitation bubble collapsing, not claws snapping
- how do fungal seeds get off of stem? e.g. jelly fungus Auricularia auricula
- surface tension catapult propels ballistopores
- spore + water droplet, theory of surface tension catapult
- droplet fuses with spore
- in yeast, 1000,000fps
- energy from surface tension of water,
- occurs <10us, 120,000 m/s2, ~300,000 occur within eye blink, average acceleration of missiles
- related to microdrop technologies
- engineers did a lot of physics to control inkjet printers
- math from inkjet printers informed understanding of spore dispersal
- includes photo of daughter because she wants her to
- faster things, turtles, jely fish, etc.
- basic research: how can we apply it? // missed something important here
3 Mantis Shrimp
- Odontodactylus scyllarus, peacock mantis shrimp
- Australia, Indonesia, size of cigar
- durable snail destroyed with a single blow
- Sheila works on sound production (not even caring about noise of impact)
- you can hear the cavitation bubble's collapse, louder than the shell cracking
- 1.8ms, 150 within a blink, acceleration 105 m/s2
- mechanics of strike
- muscle holds latch that prevents hammer from swinging; elastic energy stored
- the effect is stronger than any muscle contraction known
- same mechanism used across all 5000 known mantis shrimps (some using different things like spears)
- Cavitation bubble kind of spreads out
- mandibles degrade due to them, but molting replaces them
- impact forces used to be hard to measure, new technology with
piezoelectric crystals to record force and hydrophones to also
- measured over 400Newtons
- two force peaks, limb impact and cavitation impact or second hit
- had to record at 100,000 fps
- appendage not hitting twice
- pairing video with force sensor
- cavitation bubble here is half as strong as the limb impact (typically, cavitation bubbles can be 2-3x stronger than original impact)
- compared impacts against horn shark, Horn Shark has longer sustained
force, and it's about the same force as a Mantis shrimp, latter working in a few microseconds, former in almost one second
- but the horn shark is 3kg an the shrimp 40g
- informs snail shell's evolution
- Maya deVries looked at Lysiosquillina maculata, spearing strikes, longer reach, slower speeds, no cavitation
- 25ms, 10 within a blink, 0.3m/s2
- connected to other shrimps, co-evolved, same mechanism
- not that fast, don't need to be super fast to hunt; need minimum speeds
- so no cavitation
- extreme speeds usually the byproduct of some other goal
- evolved as early as ~300 million years ago
- nematocysts, jelly fish, smallest duration action is 0.7us
|100-300||trap-jaw ants, dogwood spores, bladderworts|
|67||trap-jaw ants, termite jaws|
5 Trap-jaw Ants
- Trap-jaw ant, Odontomachus bauri, trigger hairs, scale bars = 0.5mm for size of mandibles, trigger hairs near mouth bypass the brain and trigger jaws immediately.
- truly fast movement requires spring+latch, can't just use muscles
- latches block closing, latches moved away and jaws snap
- these are slightly faster than things she studied, but they do it in air so it doesn't count
- they have horrible stingers
- can be viewed when slowed by 1000x, occur in <0.13ms, 2000 within an eyeblink
- jump with their jaws, how much force can they produce?
- each jaw generates 400x body weight of ant
- Patek et al. 2006, PNAS
- prey on prey that is defended, they get to knock out prey before being sprayed by acid
- she studied these ants jumping
- video is beautiful, 100x slowed
- new result => many new questions
- creates a sense of wonder
- http://www.youtube.com/watch?v=G89IcZ3PluE, 46s
- use it during battles
- these jaws have evolved in 4 separate groups, two species have evolve jumping
- Mystrium, Myrmoterus, Myrmecia, Strumigenys, Anochetus, Acanthognathus, Orectognathus
- it's about producing high forces in hunting, speed is a by-product
- basic research?
- how are they produced? how do they evolve? multipl origins, similar selective regimes
- applied research
- strong, lightweight materials, store elastic energy, withstand high impacts; mineralisation strengthening
- back to Mantis Shrimp
- fast boat propellers were disintegrating
- fast flow meeting slow flow, you get low pressure, bubbles form and
collapse, generating heat 6700°C (sun surface), light, and sound
- wears away boat propellers
- wears away shrimp appendages, thank good for molting
- mechanism used in a lot of different contexts, like Jelly Fish propulsion, poison stuff, etc.
- Ninja Bot, robotic Mantis Shrimp, biomicicry, Susanna Cox; trying to replicate (e.g. to create more durable propellers)
- why do shrimp hammers not break? Mollusk shells used to be thought
of as the most fracture-resistant things, but Mantis Shrimps break them!
- hammers have impact region and periodic region that help dissipate force
- hard materials crack easily, but you need hard to generate hard impact
- harder outer surface, layering dissipates it well, propagates crack energy into other areas to prevent cracking
- can kill things with single blows
- need solution to not destroy themselves
- they have tail plates (telson), that they can target instead of the body of
another, so that they don't go off killing the rest of their species (found by Jennifer Taylor)
- telson absorbs energy, like a punching bag
- what do you think about Canada's refocus on research funding
- plant exploding scene
- relationship between water depth and probability of cavitation, harder in lower depths; no smashing mantis shrimp at 100m (close to the max depth for them)
- are there smashers that don't cavitate?
- all smashers cavitate
- spring in Mantis Shrimp; what's the issue?
- It's exoskeleton
- energetic costs of this movement?
- huge ones, you can see their gills moving; they can only do 10 in a row before they stop and you observe their gills flapping, panting
- prey preference: bigger, more shell but more meat; smaller, less meat but less shell? middle
- molting, after can they act right away?
- they start pounding glass at her lab
- gave her daughter nightmares for 6 months after banging glass in front of her
- had to devise her antishrimp spray
- so, eventually they are too soft pre-molting, and they can't stop all together, so instead of actually striking, they display and bluff, and it's effective
- time to recharge?
- muscle contraction takes over 100ms
- now has a neurobiologist studying the neuro basis
- longer sarcameres: more force to produce, longer to contract
- smashers have really long ones, take a long time to load
- spearers have can't contract so much, but reload faster; they hunt faster, evasive pray
- how to house mantis shrimp
- urban legend says you can't store them in glass tanks
- has stored 1000s in glass tanks, and they've never broken them
- they've broken other things, like Nalgene bottles
- size component to the amount of force in a cavitation bubble
- doesn't know, but she should have measured it she says
- guesses there isn't a scaling
- actually, size of animal => size of force
You could perhaps suggest that that is a user problem, that my sensei should create an album and include videos somehow through that. I think that Google+ should detect a series of activity from the same person and group it more tightly, though.
Generally if someone complains about a user error, I translate that to mean a design error. :)
It's possible that if he had written something along with the videos embedded in this Google+ posts , that I would +1 that and not just the video, in which case it should not necessarily propagate back, but I still dislike this disconnect.
Basically, I wanted something that was hyperlinked and efficient and didn't require a web-browser and let me write in LaTeX. Annoyingly, org-mode has its own lightweight markup language (yet another...) but it's thankfully intuitive and pretty conventional (e.g. *bold*).
If you're interested, here's the elementary tutorial I'm using to introduce myself to it.
Some notes from me:
- working with Todos, it says to use C-c C-v to just show a list of them
- Instead, I have to use C-c / t, (that is, typing '/' after C-c, then t). This folds in all the other headers. To unfold them, just use tab, or shift-tab for the whole document.
- (Discovered by checking the ref card)
- for the Agenda to work properly, follow the Activation section of the guide. Elsewise, I get "C-c a is undefined"
- (Solution found here)
I used to disdain Toronto due to shifts in my priorities that left me depressed by the Eaton Centre and its populace. Eventually, though, I realised that I'm no snowflake, that there were necessarily more people who were like me here than there could be in my hometown of 700, or even in Guelph. The matter was just finding out how to find them.
Where do they go? Where do I go? It's a culture, and it probably has focal points. Places where people go, and go because people like them build homes away from homes. In my case, small, individual shops on Queen street, Kensington Market, etc. You can tell how unoriginal I am; these locations are hard to separate from what's trendy and hip. Then there are more niche places, like today I discovered Bento Miso, a creative workspace in Toronto where TCAF's Bit Bazaar was held today. And it was very comfortable. Indie game makers presented small, beautiful and fun games, alongside related art. It was relatively small, and the atmosphere was very welcoming. I even made a random pseudofriend just by chatting.
But the larger the city, the more stimulation there is on everyone, and the greater the need to filter. In Vancouver, I had complained a bit that the social atmosphere was cold. In Guelph, I felt strangers were more friendly and welcoming. In my hometown of 700, they're almost too welcoming, downright nosy. But when you meet a new person no more than once a week, it's easy to find the meeting interesting and curious, as opposed to when you see a new face every 3 seconds.
It makes sense for people to be cold, to build up a barrier against the surrounding world, to control the input that they let in, and to be picky about it. So their are more potential friends in a large city, but a larger barrier to both finding them and then warranting interaction with them.
Networks are so fundamental. Nepotism has a bit of a bad reputation, but trust is important to keep yourself and your interests safe. Lots of people can not help you in your life, and will instead be a source of friction, and it's important to limit that, and relying on friends as filters for new people is invaluable.
The next time I live in a large city, I hope to do it better. Find contexts in which to exist, to be friendly and visible and helpful, and incrementally let people understand who I am and give them the choice to let me in. I think that will be my gateway into new, exciting worlds. It's working in Guelph so far, and I look forward to exploring larger worlds, more infinite than I can imagine.
Linux support for MTP with Android on the Galaxy Nexus has gotten better but is still almost unusable. Last year when I tried, I could not reliably navigate directories. Today, Nautilus was able to successfully navigate directories, and was able to thumbnail images in /sdcard/DCIM/Camera without blocking! However, when I tried to cut and paste files onto my local hard drive, it would copy a few but then block interminably and I'd have to unplug the device. I didn't lose any photos doing this, though. (Hooray for software that copies first and then unlinks the source file.) It was also very slow, with the transfer occurring at about 114kB/s on average.
I checked whether PTP worked any better than last year. Last year, it worked better than MTP, but still had issues. This time, I was able to initiate transfers at quite a fast speed, but invariably after about ten or so photos were copied, it too would stall. Unlike with MTP, nautilus itself did not freeze. I could re-initiate a cut-and-paste, but that would stall too.
So, for now, it's almost usable, but I'm still going to use the Android debugger (adb), as I mentioned last year.
sudo adb start-server # after getting adb from android-sdk-linux/platform-tools
adb pull /sdcard/DCIM/photos/ ~/newpictures/
adb shell # so I can delete them from the phone after import
- the ticket centre sells only Mi transit tickets, but there is a Go booth near the highway
- the ticket centre will direct you to the Go booth, even though the booth closes at 7PM and it is after that, stranding evening shoppers
- Go uses Presto cards
- the Presto balance checker requires a lot of fiddling of the card to get it to read the balance
- the balance disappears after appearing for only a second
- you cannot add to your balance at a machine at Square One (as you can at Union and in Guelph)
- you can add to your balance online by visiting Presto's website
- the web interface for adding to your balance has many pages (fewer would be better)
- payment by (visa) credit card requires a Verified by Visa password. I don't remember when I even set that up, as I can't recall the last time a website wanted that, but I successfully guessed it (phew)
- after adding $20, I was told that it could take up to 24 hours to process, and that I would receive an e-mail when that was complete; that prevents you from being able to add funds to your card in a timely fashion if you are short before a trip
- I received an e-mail 5 minutes later indicating that it was processed (phew), but then I read that my balance may take 24 hours to be updated (what, still?!)
- I checked my balance 10 minutes later and indeed it was still not up to date
- I asked a Go bus driver how I could buy a ticket, he suggested the only way was to pay the driver with cash. It's nice that they accept cash (whereas Greyhound does not)
- I asked at the nearby Starbucks where the nearest ATM was. They suggested Playdium (across the street) or Jack Astors (further away from my bus), so I went to the former.
- The Playdium's ATM machine was out of funds.
- Jack Astors' ATM machine was busy, but eventually I had my turned and withdrew my money.
- I ultimately paid in cash for my fare when my bus arrived.
In March 1989, British physicist Tim Berners-Lee wrote a proposal to develop a distributed information system for CERN physicists and engineers. It described a way of managing information about the accelerators and experiments at the laboratory using a system of documents linked together and accessible via the internet. His supervisor, Mike Sendall, wrote “vague, but exciting” on the cover of the proposal, and, with those words, gave the green light to an information revolution.
