Pandemic Diary #23, 07 Sep 2020 – Figs, Chinese IME, International relations, Arduino cat books, Coursera Russian, Research

Figs

Okay what’s up with the rest. Went fig picking today, more fun than I imagined. One of dogs is very sick though, only two made it out with us 🙁

Social Life

Regular social schedule: Avatar (ep 17 next), puzzles with assorted people (curious cookoff — good quality, decided to chip in recommended amount). Avatar: simple stories, but the animation and sound and world-building are all great. Slowly drawing more people into puzzle hunts… hope to bring new folks to MIT Mystery Hunt. Sporadic 2redbeans, Speaky, Chinese penpals, LingQ for chinese content with subtitles and popup definitions

Academics

Coursera – has Russian course for auditing, https://www.coursera.org/learn/russian-alphabet/exam/4RDrE/exercises-alphabet, keybr to learn russian keyboard, 6.341 intro to prob on Edx (can never hurt to refresh on stats) (OCW, more practice). TAing CS109a for some structure – have a friend TAing so that will make things better, plus they have something like 30 TAs due to hiring undergrads so it takes some of the pressure off for timely response / TAing long office hours. Hoping to have a fun TA experience — I’ve only had stressful ones so far, due to having to TA for funding or while being on egg shells around my advisor or classes.

Treasure hunts / Moving

Cleaning! I was going to talk about what I call a “treasure hunt” — finding all sorts of stuff by cleaning out old bookshelves, keeping the good stuff (handwritten diaries etc.) and donating/throwing out the junk (outdated books, mass paperback common books that can be e-bought). Realized — Gosh, forgot the whole ordeal last weekend. Went to Boston and moved all my stuff out. By “went” I mean drove the 2000+ miles with my parents, returning with all my stuff including two bikes. Somehow survived just fine. Don’t ever want to do it again – plan to ship stuff back up / fly with it a few boxes at a time. January… I will know the next president by then!! Better hecking be Biden.
Things learned: sometimes pick intermediate cities for better traffic routing. “service areas” up north, “rest stops” down south – service areas have gas restrooms and parking lots for sleeping; rest stops just have restrooms and parking lots; be prepared to navigate after toll booths – a lot of route changes can happen just getting out

Starting, on the way back

Sold a bunch of furniture on Facebook Marketplace and craigslist for the first time. Surprisingly easy.

Keeping an eye out for autonomous sailboat activities still. (Finished reading most chapters of “voyaging handbook” a while ago). Dreaming still!! With dinghies it’s nice – can feel my improvement each day, and satisfies my desire for independence from others.

Chinese input, typewriters, regional dialects

Listened to radiolab episode about wubi zi https://www.wnycstudios.org/podcasts/radiolab/articles/wubi-effect. Interesting points: At one point Mao had committee for getting rid of Chinese characters. The invention of wubi disbanded that – and in speed competitions wubi input often wins still. How wubi declined due to government promotion of pinyin, which apparently might be sort of a push toward more uniform pronunciation.

I can feel that effort since my parents are southern and the zi zhi ci chi distinction are less prominent, making it hard to for me to type using pinyin.

Talk by what appears to be… a nerd collecting normal typewriters sucked into a years-long rabbit hole about the history of Chinese (mechanical) typewriters involving making a museum exhibit, giving talks, running a Kickstarter, and writing two books.

Impact of predictive input (for mobile phones)

Toward the end Mullaney talks a bit about predictive input in Chinese — I realized that some of the words I try to say in Chinese I don’t know how to write, and don’t pop up on the cellphone menu — they’re actually regional sayings, making much harder to input, and how that might standardize not just pronunciation but also language/dialect. To find: go to baidu.com and type in the pinyin, and the “suggested search” results will include how to “spell” the words.

This is what it looks like when the predictive input fails and you have to find the exact character you want… very annoying, usually faster to type a full two-character saying and backspace out the extra character.

Full pinyin

Apparently Vannevar Bush from MIT did work related to the Chinese input methods as well. He didn’t know there is a stroke order — I didn’t think about this, but yea, there’s a consistency so that everyone draws the character in the same order of strokes, which can be exploited for decomposing characters into orderly inputs.

I guess this must have come later, but actually in a dictionary you can look up by the radical and then the number of additional strokes. Works fairly well.

A fairly predictable outcome of having computers is the standardization of writing – “setting in stone”. For instance, we developed lowercase letters from uppercase letters over centuries of lazy writing. Hirigana in Japanese also come from Chinese characters (apparently?). So, letters stop “evolving”.

At the sentence levels, there’s studies about English in which people wrote shorter less descriptive captions of images when using autocomplete. https://www.seas.harvard.edu/news/2020/05/predictive-text-systems-change-what-we-write

What I didn’t think about was – the impact of Chinese predictive input, on regional dialects, not just the pronunciation but also the sayings used! See “baidu” image earlier.

Though there is this narrative of the “Chinese government removing individuality”, fortunately in real life there is still a lot of regional pride. I found a game show on youtube testing people’s knowledge of jiang xi nan chang fang yan, which is the regional dialect my parents know (but I don’t know). 江西南昌方言。

Chinese Assistive Tech

This brings up the interesting question of how alternative input works for the disabled, in languages other than English. There’s the iconic view of Stephen Hawkings (RIP) who could only move his eyes but still interfaced well to a a voice producer using eye movements. What if you don’t speak English though? What are assistive computer interfaces like for non English typing… I did a brief google search and couldn’t find.

Feelings about the wider world

I’ve apparently totally given up on activism which I feel greatly conflicted about. We’re up to what – almost 190k deaths (188.8 thousand), 6.3 million cases, 30-40k new cases daily, just under 1000 people dying every day – and I can’t find the energy to do anything. It all just feels so, so futile. No new stimulus check of benefits for the 1/8 Americans who are hungry. A president supporting conspiracy theories and declaring things “un-American” and straight up supporting killers and conspiracy theories, surrounding himself with quackpots.

I know what I think should happen – put the public health epidemiologists in charge. Don’t listen to the business people. Think long term (3 months) rather than short term (2 weeks). Seriously, what the fk people. There’s regional bright spots – NYC is doing a lot better. But the country as a whole… and Trump’s (low) approval remains unchanging among his supporters. We can only hope that they’re still disincentivized from voting.

Okay, that was a long rant. But I feel like I wrote these op-eds and did this campaign and what – nothing happened. The optimism I got from when the protests turned out to be way more successful than I thought – when I though the youth of the US were united – to see the multiethnic protests, it brought such optimism. But now predictably people are forgetting and becoming less open to the protests. Pandemic activism probably in part cost me ⬜⬜⬜⬜, so I feel compelled to put it up on my resume (nrobot.dev). But feel slimy doing so. The op-eds, petitions – by themselves they are nothing without the work to build a whole environment of activism around it, emailing legislators etc. (Another thing I was shocked by in my correspondence – that many state reps are pretty Trumpian in being okay with conspiracy theories and racism and anti-Semitism and the whole nine yards – cf radiolab “flag and the fury” that many state reps in MI still went to segrationist schools growing up).

Not sure how to volunteer on COVID or politically in a way that will help. Hoping to take a week off, two weeks before Election Day – help people get their absentee ballots in. Used a drive-by drop box for the first time this year.

Arduino and Cats

I’ve been working on writing up the Arduino tutorials we did during summer camp for a while now. Lack of focus, tried to figure out how to tie all the projects together, make it actually useful, make it different than others on the market (there’s a book “65 projects with Arduino” or something… I even learned from the sample pages about the REF for reference voltage on Arduino I’d never looked into!). Finally decided to orient around a cat / pets theme. Doesn’t seem to exist on the market, so it’ll give clear guidance around how to structure the material. Will be obligatory to make it super cute…!

Research

We’re in stealth mode for now… Scheduling meetings with people, reading papers, getting work done.

International Relations

Getting late, I’ll just make a list for now.

https://www.goodreads.com/book/show/31125556-destined-for-war – covers history so not 100% US-China centric; very interesting to read comments that are very articulate and then include theories such as “chinese with their lack of individuality in society will never truly innovate” — from 2017! now in 2020 other countries are banning 5G tech from China that their own companies can’t produce for such cost. interesting to see these theories versus what actually happens. –> bought on play books to read! after guns germs and steel

https://www.goodreads.com/book/show/90540.Overthrow from the person interviewed in https://www.youtube.com/watch?v=pTmYGY_shFw – was curious – doesn’t actually answer the question in the title! (how many countries has US invaded)

Nice list of documentaries https://www.youtube.com/c/DWDocumentary/videos from what seems to be the German equivalent of NPR

Reading from friend – https://www.rollingstone.com/politics/political-commentary/covid-19-end-of-american-era-wade-davis-1038206/

Also first time heard of Bradykinin storm – interesting to see science emerge in realtime about all the unknowns of this virus!

https://elemental.medium.com/a-supercomputer-analyzed-covid-19-and-an-interesting-new-theory-has-emerged-31cb8eba9d63
“According to the team’s findings, a Covid-19 infection generally begins when the virus enters the body through ACE2 receptors in the nose … a bradykinin storm — a massive, runaway buildup of bradykinin in the body …. dramatically increases vascular permeability. In short, it makes your blood vessels leaky. This aligns with recent clinical data, which increasingly views Covid-19 primarily as a vascular disease, rather than a respiratory one. But Covid-19 still has a massive effect on the lungs. As blood vessels start to leak due to a bradykinin storm, the researchers say, the lungs can fill with fluid. … it increases production of hyaluronic acid (HLA) in the lungs… When it combines with fluid leaking into the lungs, the results are disastrous: It forms a hydrogel, which can fill the lungs in some patients… “Regardless of how much oxygen you pump in, it doesn’t matter, because the alveoli in the lungs are filled with this hydrogel,” Jacobson says. “The lungs become like a water balloon.” … Patients can suffocate even while receiving full breathing support

Alright, going to end there. Parting image…

It begins

Pandemic Diary #18, 26 July 2020 –

It’s been a while since the last post. I’m not sure why I’ve found it so difficult to remember to journal, and instead spend my downtime  reading the news / playing with the cat. I suppose a lot of stuff has happened that I don’t feel comfortable talking about publicly, which has hindered my journaling.

Currently: Mad about governor suing atlanta mayor to strike down mask mandate. Mad at politicians in general for thinking they know better than history and health experts. A lot of ABSURD things – e.g. the secretary of state website about elections essentially running negative campaign against Abrams and her campaign to get people to vote. (??)

Started: Using OBS Studio and livestreaming.

Taught cat a few more tricks. Attached xioami band to her collar. Cat toilet training: going kinda poorly. Soon: teach cat to use buttons to speak?

Need to clean all rooms. Need to throw things out and reclaim spaces. Need to set up lasercutter.

Finally sorted out YNAB today. Has a confusing mindset on savings: that you want to have a *purpose* for them, or else it’s easy to “steal” from them for random splurges. Forced me to put in some financial goals, which are really the same a life goals. Also put into perspective my “charity deficit” if I’m really aiming for around 10% of my income (that is probably too high, for a grad student income. 50/30/20 – 50% needs, 30% wants, 20% wishes). Savings – looked up the standard stuff, like how much down payment on house, kids, etc. cost. Running for Congress — about $300k to start, for House (!). Must try to think of how it will be worthwhile even if I lose. Harvard probably owes me money still. Sort out soon. Make retainer molds (perpetually putting this off, and anything I think can’t do perfectly).

Is the money not better spent instead of political ads, on public education about wearing masks and staying inside??

Special election – nov 3 – make sure to keep on radar. https://en.wikipedia.org/wiki/2020_United_States_Senate_special_election_in_Georgia

Todo: research those two candidates.

I’m thinking: phd by publication. Power of union?

Videos watched today: yoga 15 mins. (set up with chromecast / cron script). electrostatic mlem. trevor noah.

Read: washpost, nytimes. Understand: why is NAACP not tax deductible (to free it to do more political activism – donate to charitable sister org instead). (biden victory fund – first few thousands go to biden, next thousands to DNC, then next thousands to state parties). Life you can save vs give well – more gender parity organizations in former. (Is it imperialistic giving? Paternalistic to have this effective altruism outlook?). I have strong feelings after living few a few weeks in place with no running water / little electricity / basically no streetlamps, hence my 80% split toward non-US nonprofits). 80k hours – guess I’m on my way as an AI researcher and with expertise in China. (Found a pen pal on speaky – hope to increase conversations more). A lot of my chinese is grammatically incorrect. Still motivated by how, when I went on my own to see my ?great aunt?, it felt impossible to communicate anything more complicated than “love you” – things about college, economy, politics totally misunderstood.

Bought a lot from IKEA to remodel mom’s kitchen. Will arrive in a month (delivery). Wanted to pick up, but no openings online. I think if I had infinite money I’d spend some significant portion on IKEA lol. It has so many well thought out, inexpensive things. (Though, still I have two water bottles I rarely use — I always feel like my water might be kinda moldy).

Saw comet two days ago!!! 😀

Am happy to get my hands on a digit.ml soon – want to play around with camera. Cool to see others joining in order!

(important to have healthy media diet, and be aware of biases in intake!)

Savings – actually starting to invest my Roth. Pretty cool to see.
Need more side money — and build up portfolio – how? (Banks?)
Need to apply to more awards – look more enticing to people

Roses still doing poorly. Need to mulch to get rid of future weeds. Not sure best practices (do I need to weed beforehand?). Need to do more dishes and cooking. Have more “date nights” with parents, that’s what I want! (Virtual museum visits? Karaoke?)

Uncertain about going back in September. Want to, but feel like I have so much to do. Want to take a semester off to focus on myself, my family, and my career, on ways to address COVID, on volunteering and mentoring. Not sure how to run past parents. Won’t have major costs? Just health insurance. Want to push out quals. Otherwise, teaching – could be not too stressful? Not sure. (Probably not).

“Study with me” livestreams on youtube for quarantine coworking. & other productivity notes

If you go on youtube and search for “study with me, live”, you’ll find many people livestreaming themselves studying.

https://www.youtube.com/results?search_query=study+with+me%2C+live

I found these a while back, but have lately gotten really into them. I guess it is a natural extension of coworking in the same cafe, to an online setting. Though many days I cowork with my friends, which is usually more effective. Still, sometimes no one is around, we are in different time zones, etc.

It is interesting to see what people are working toward, and it is inspiring to see people working 10 hours a day. And some have days on a roll as well, going into the 100+ days.

It is also interesting to peek into people’s work zones across the world. And, to see the different subjects people are studying. Most of the videos come from Korea. They are offset by about 12 hours, so many of them come online around 8pm, which is 9am there I think. Other people start studying at 6am. Others stop studying at 1am. So, at the 9 or 10am eastern time point, which is usually when I start work, there are more from the US or related time zones.

Here are some examples on youtube.

Some have cats too 🙂

Many (most?) follow the pomodoro technique in various time scales. (30 mins, 1 hr, 1.5 hr, 3 hr, etc.).

I found also someone else saying, they did not start out studying 10 hours in a row at once, in disciplined manner. To build up to it. So, I have been doing that. Formally, I have excessive daytime sleepiness, which sometimes throws a huge wrench in the works of trying to keep a consistent schedule. But I have found a way that allows me to flex around that. Usually, I will crash for about 1.5 hrs before I am able to drag myself awake. So, I have picked 1.5 hr long pomodoros. (75 min work, 15 mins break). And these are easily split up into 3 chunks. So, I have a goal of how many pomodoros to complete, and if I crash during one session, that is okay, I just have to complete the rest.

It may look something like this (and yes, I was into dot grid notebooks before it was cool).

Finally, I found an app on Android I like, called good timer. It is minimalist and no ads. So, I can keep track of how long I am able to concentrate, and it discourages my phone use.

Finally, it is possible to set both samsung android phone, and ubuntu, to grayscale, which can make computers more boring. On android, my phone has “color adjustment” pre-installed, which I can just turn on.

On ubuntu 18.04, gnome-shell version 3.28.4 – Tint all extension–  Install with two clicks, then change color by just clicking the palette icon on the toolbar.
