ryanchoi··on Learn Claude Code by doing, not reading
I was a bit confused by the quiz results as well. But it's just a bug :)

Level ranges for the 10 questions (the score ranges are in the html): Beginner 0~3, Intermediate 4~7, Advanced 8~10

Makes sense. But:

- You get 0 points if you press A/B, 1 point if you press C, 2 points if you press D

- Scoring uses a fallback to Beginner level if your total score exceeds the expected max which is 10

`const t = Object.values(r).find(a => l >= a.min && l <= a.max) ?? r.beginner`

Pressed D 5x then A 5x, got Advanced

ryanchoi··on YouTube No Translation
Looking for this was my first instinct as well. Mindboggling how there's no toggle for this
ryanchoi··on FB feed is 98% suggested pages and barely any friends' posts
I’ve found the same thing but for Instagram, though I think it might be similar on Facebook too. It’s just that when I’m on Facebook it’s only to check out some things in a few hobby related groups I’m in so I’m never on home feed.
ryanchoi··on Building my first mechanical keyboard
If one isn’t afraid to tinker a little more while building keyboards one could work in a nice!nano or similar replacement for pro micros/elite-Cs, I had a fine time building a kyria (a 40% split) with it too:

If you’re into low profile switches (that’s a big if!) there are projects the corneish zen https://lowprokb.ca/products/corne-ish-zen

ryanchoi··on Feeling uncomfortable when leaving phone at home shouldn't be normal
Yeah, I opted for a smaller phone this last upgrade (in what, four years) in hopes of using it less and being less noticeable in the pocket. Used to have this big screen phone with which I wouldn’t have much issue watching or reading stuff on. Now with a much smaller one, “not” having a huge screen to consume media on, making it less attractive to do so, and it’s been working pretty well I think. Couldn’t bring myself to go full dumbphone, er, feature? phone.
ryanchoi··on What a deepfake video of Mark Zuckerberg reveals about how we're manipulated
I think I agree. People already take political "memes" (some text on an image, designed to provoke reaction) for granted, and still-images are easier/faster to consume, and create, than videos.
ryanchoi··on Sunscreen enters bloodstream after just one day of use
The four ingredients here (avobenzone, oxybenzone, ecamsule and octocrylene) seem to be specific to chemical* sunscreens, as opposed the sunscreens that are "physical" like Titanium dioxide/zinc oxide based ones.

They're like the ones in the Hawaii ban on some otc sunscreens (on oxybenzone and octinoxate) because those two chemicals appear to be particularly bad for coral reefs or something.

Then again, there is ofc the issue of nanoscale particles on your face passing through your own skin, but that sounds like it applies for a lot of modern makeup anyways. And for that, I take it cosmetics R&D people already have something on this...(?)

(*Chemical/physical sunscreens are categorized by their uv protection mechanisms: the former type generally uses organic compounds to absorb uv, the latter type uses inorganic compounds to generally just reflect/scatter, to loosely put it)

ryanchoi··on Bored Lonely Angry Stupid
Happy to hear you've got yourself back on track :)

I heard/hold a similar take on depression that sounds a little nicer, for better or for worse: it's an issue for which you must seek the answer to on your own, but the problem is that the condition itself takes away your motivation to do anything about it...

ryanchoi··on Adblock Plus filter lists may execute arbitrary code in web pages
Agreed, in the same way all touchscreen smartphones were/are(?) called iPhones, or people calling all tissues Kleenexes in the US, I think for a huge fraction of laypersons, ABP has an understandably strong grasp on the product category.
ryanchoi··on At the Blackboard: Kurt Vonnegut diagrams the shapes of stories (2005)

ryanchoi··on Facebook Knows How to Track You Using the Dust on Your Camera Lens
Above user might not find it to be a hassle at all. I turn GPS off whenever I notice it on as well, but it's pretty far down the list of ux concerns when using my phone. Sometimes an app reminds me I need to turn it on before continuing, but that's all handled smoothly in-app these days. (unlike sibling comment my phone has gps toggle in the slide down menu)

In my case it's a longstanding habit from when I was told that GPS could drain battery faster :p (maybe it still? does, I don't know)

ryanchoi··on Two years later, I still miss the headphone port
I definitely care more than the average person, but all things considered I prefer my wired IEMs over over-ear wireless headphones, or today's chunky earbuds that need to be charged too often for my liking (and/or their charging cases, to be exact). Same reason I didn't get into smart watches, the pros were outweighed by the cons. But like wireless gaming-grade mice, I think we'll get there with audio.

I'm the meantime I'll be keeping an eye out for the 3.5" jack in the future, I guess. I do think that it's very convenient to not fiddle with wires, but I like the choice I have now: Preferred shape/sound, vs all the friction associated with wires (sorry ;).

The way I see it, if wireless is here to stay, my situation should only last until someone comes up with a wireless product that I like more than today's lineup. It's just that I prefer my wired setup for the time being!

ryanchoi··on “Genuine people personalities” are coming to our gadgets?
I haven't used Waze in a long time but i seem to recall them having a similar feature a few years back... But they were temporary (promotional?) and may or may not work anymore. Maybe it takes some fiddling.

A reddit thread with some waze voice packs: https://www.reddit.com/r/waze/comments/3pi5yl/waze_voice_pac...

ryanchoi··on Show HN: Wiv.js – A library for a more wiggly div
This is guilt-trippingly sweet, there's a certain charm I get from this, kind of like that of tacky Christmas sweaters or unironically used comic sans :)
ryanchoi··on Ask HN: What technologies did you learn in 2018?
In terms of tech: react native, vue, ffmpeg. There's still lots to delve into on these items of course..!

In terms of more foundational things I tried to brush up on linear algebra. Lacking a formal/rigorous college course experience in linalg, I used LAFF from edX before MIT OCW/Prof. Strang's online lectures. I liked both. LAFF was pretty easy/fun, but ymmv, I knew matlab and python (you may see one or the other depending on what year archive you look at) and my undergrad was in a computer-unrelated engineering field (whose math curriculum focused far more on diffEQs which is why I never got deep into linalg much before)

Next year for fundamentals, I'll try to get a better base of statistics and probability. I'm quite weak in the latter.

ryanchoi··on Ask HN: What are job interview questions that can be used to reject regardless
I figure you wanted to defend your take regardless, but the quotes indicated to me that the parent was posing as the company that wanted to reject the candidate no matter what the answer was. :)
ryanchoi··on California moves toward permanent daylight saving time
Arizona and Hawaii are already on standard time throughout the entire year, so I assume that a similar exemption statute will be needed that starts at the state level?

ryanchoi··on A tweet storm explaining the history and state of Ethereum's Casper research
Unrolled tweets: https://threadreaderapp.com/thread/1029900695925706753.html

It's certainly interesting to read about new efforts to bring about PoS in a way that isn't another dPoS take...

But wow, I don't usually care about chained tweets, yet I can't help but to notice this being 75 tweets long (!?) This isn't just banter type of stuff or responding to tweets, it's a research history recap, something that'd be nice to be searchable a month from now. Amusingly he links to his own blog posts during all this (1). I wonder why he wouldn't just use that? :/

ryanchoi··on Amazon in Running to Acquire Landmark Movie Chain
Not sure if this applies to this scenario, but tricky wording related to 1 day delivery landed amzn in hot water in the UK. In this case, they meant one day after dispatch, not one day from order placement.

ryanchoi··on Certified Translator, stuck in Venezuela, looking for remote freelance work
I know people have concerns with altcoin longevity/soundness/security but in a situation where every cent matters maybe an additional crypto to accept would be NANO? Though it seems to be less bartered locally. I read this a few days ago https://www.reddit.com/r/nanocurrency/comments/8wfl2r/venezu...

edit: Oh never mind, moments after I posted this i realized that with altcoins you could end up even less crypto worth vs BTC than you'd save on tx cost. :)

ryanchoi··on The F-106A That Flew Itself – After the Pilot Ejected, Landing Gently in a Field
To me it generally came across as "self-indulgent" where authors write for themselves more than the readers. Cynically I can just imagine the author thinking "oh yes that's clever" while writing this part... And with AI in the media these days, it may just confuse readers. And for what, to fit in some fancy anthropomorphism?

But I don't think I'm using the term quite right, this seems to be a more specific issue in fiction.

ryanchoi··on U.S. Regulators to Subpoena Crypto Exchange Bitfinex, Tether
There's a reason to temporarily move from say BTC to USDT: If you think bitcoin/crypto currency is going to trend downwards for a bit and your exchanges don't have fiat balances (so the vast majority of them?) you sell your cryptos for USDT, wait for cryptocurrency prices to fall, then re-trade your USDT for more BITCOIN or whatever. Then you have accumulated more bitcoin (the premise is that you think it'll go up again). Edit: ninja'd.
ryanchoi··on OpenAI at the Dota 2 World Championships
The method the reddit commenter (menohaxor) described to beat the openAI bot reminds me of the Go Deepmind Showmatch, Game 4, Move 78, where Lee Sedol made a highly unorthodox move. I'm reminded of this because in any serious 1v1 mid SF match, no one would try to win in the way by baiting enemy creeps into the jungle repeatedly to win by slowly chipping away at the T1 tower, it actually sounds like a joke on paper. So it seems that for the time being, in real-time games like dota and Starcraft, unorthodox plays and cheese strats could be very effective.
ryanchoi··on Government Report Finds Drastic Impact of Climate Change on U.S
AFAIK drafts are already viewable (if this is what you meant?), ex: https://www.nytimes.com/interactive/2017/08/07/climate/docum...

With the public draft already released, I think it would be especially surprising if the administration tried to impose non-trivial changes to the document.

ryanchoi··on Government Report Finds Drastic Impact of Climate Change on U.S
I don't notice the anomalies myself (well, I live in a west coast suburb...) However I stumbled upon a pretty cool visualization on temperature anomalies on Twitter a few days ago: https://www.flickr.com/photos/150411108@N06/35471910724/in/p...
ryanchoi··on Algorithm That Makes Preschoolers Obsessed with YouTube
Wow. I've seen these on my feed and was sure (until now) that they were just jokes. Or maybe they are, and young kids just react differently.
ryanchoi··on Data Science: CSCI E-109 Publication Listing
Yes, while there are often some reused patterns (eg course 1xx being an intro course in many colleges) as we see here it certainly doesn't hold everywhere. For the most part there's no intercollegiate guarantee that bio150 at college X == bio150 at college Y.
ryanchoi··on Why do so many people continue to pursue doctorates?
You might have luck as a lab technician and seeing where that leads you, maybe.
