aganders3··on Type hinting for Python
I think I could get over that, but the idea of putting this hinting in comments is troubling for me:

    x = {}    # type: Dict[str, str]
I mean, it's very human-readable so it makes sense as a comment. It's optional, so not every declaration will have it. Still, something about the interpreter reading my comments is off-putting.
aganders3··on Why Silicon Valley Works
It's better not to go on feel either way. In most cases, a freelance writer retains copyright and the publication that paid for the work (in this case FT) is given an implicit license to use it.

Note that EMTALA only requires hospitals to give you stabilizing treatment.
aganders3··on Audacious Plan to Make Electricity as Easy as WiFi
That quote from the FDA is referring to ultrasound imaging, which is performed with transducers in direct contact with the body. Even in those instances, ultrasound is regarded as one of the safest medical imaging techniques.

Nonetheless, while I suspect this technology is safe, I agree they shouldn't hand-wave over that aspect.

aganders3··on Cursors
The control is hard if you disable the cursor lock, which I had to do to get it to work in Safari. If you lose track of your "game" cursor, you get the red circle around your "real" cursor until you link them back up.

It worked as expected for me in Chrome (then I went back and tried it in Safari after figuring it out).

aganders3··on Cursors
Ahh, that's what the "Area too full, drawing is disabled" was for. I saw some drawing in a later level and didn't connect the dots.
aganders3··on The USSR used a nuclear charge to stop a gas well fire in 1966
The US proposed many peaceful uses of nuclear explosives, mostly in the 60s. The catchall term for these proposals was "Project Plowshare" or "Operation Plowshare" [0].

> And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruning hooks: nation shall not lift up sword against nation, neither shall they learn war any more - Isaiah 2:3-5

aganders3··on Dollar a Day
An interesting take on this would be each day having to say "nope" to the nonprofit if you wanted to skip it. Make it an opt-out donation each morning (or a chosen time).

You could defer all the "no" dollars into a pile so the user could add a bonus dollar in the same way for another day.

Edit: I think you added this to your reply already! I love the idea, though.

aganders3··on Trends in the Silk Road 2.0
I would guess the market pricing for personal quantities of Silk Road weed (including shipping) is more in line with legal/medical prices rather than local black market prices.

Potentially, but death is still pretty rare with impure MDMA and the effects can be felt. It's also a social drug, so I would imagine most buyers purchasing ~tens of pills and sharing them with friends. One would probably leave a bad review if a friend died.

Testing kits and services are also available so you could review the quality without even taking the drug.

aganders3··on How Memorizing “$19.05” Can Help You Outsmart the MTA
If all rides cost the same (i.e. price is not dependent on distance traveled) why don't they sell cards with X number of rides on them? The "rides" on the card could act like forever stamps, in that they would be valid even if the price per ride someday increased. This seems like a much fairer system that would still encourage people to buy in advance and keep their cards.
aganders3··on Isolating Football Player Movement by Eliminating Camera Motion
As the watermark is static in the original footage, it should be easy to remove before processing.

I'd like to see the players remain, perhaps somewhat transparent, once they are cropped out of the actual shot. Otherwise the zoom/pan just erases them.

aganders3··on Update to Celebrity Photo Investigation
Most 2FA schemes give you some backup codes. I'm sure people use Find My iPhone differently, but it's not unreasonable to suspect them to be used rarely. Once your device is back in-hand you could generate a few new backup codes.
aganders3··on YC Demo Day Session 1
My (very limited) understanding of the lawsuits brought by musicians is that it stems from a desire (by the artist) to keep ticket prices low. TicketMaster has exclusive contracts with many venues, preventing artists from selling tickets directly to fans or through other ticketing services.
aganders3··on YC Demo Day Session 1
I can't speak to their overhead, but the fees certainly seem excessive and in some cases insulting (e.g. at-home ticket printing convenience fees).

They have also been criticized, sued, and investigated for anti-trust practices. In fairness, I don't think any of these challenges have been successful (though some have been settled and the terms are not public).

aganders3··on YC Demo Day Session 1
Not sure. Maybe tickets live only on your phone and are non-transferable?
aganders3··on YC Demo Day Session 1
TicketLabs will have an uphill battle against TicketMaster, but man do I hope they succeed.
aganders3··on How to Make the Best Pourover Coffee
I think pour-over with a disposable filter is probably comparable in ease of cleaning.
aganders3··on How to Make the Best Pourover Coffee
I grind fresh for my Aeropress, but use pre-ground (or grind-at-the-store) for cold brew and try to make it that day. You can do it in a large mason jar with several paper filters, but I use a Toddy system I got as a gift.

Basically it's 12 OZ ground coffee + 7 cups of water in the bucket. I let that sit on the counter for 12-24 hours, then run it through a very fine filter (~1 cm thick piece of felt). This produces a concentrate that I store in the fridge. Dilute 1:1 or 1:2 with milk and/or water before drinking. It's good heated or over ice.

aganders3··on How to Make the Best Pourover Coffee
I do this with a Toddy, and previously with large mason jars. It tastes great heated and makes for the best iced coffee. I love that I can dilute entirely with milk or water. You're right it tastes good for up to 2 weeks or so, but do you know anything about the caffeine content through that time? I figure (especially in the fridge) it should be pretty stable, but I don't have the domain knowledge to be certain of this.
aganders3··on Neglected machine learning ideas
I would read it! I work with a specific kind of high(er) dimensional medical imaging data, and I think unsupervised learning could be used for classification and foreground separation. K-means is giving me some promising preliminary results, but I'd like to assign samples continuous probabilities rather than binary classifications. I'm relatively new to ML but trying to incorporate it into my research, so I apologize if any of that doesn't make sense!
aganders3··on Neglected machine learning ideas
I would love to see more books/articles/blogs on unsupervised learning and ensemble techniques. E.G. - can I use k-means clustering as input to train a naïve Bayes classifier?
aganders3··on “You're not allowed science any more”
> Except that those who are "proud to be bad at math" exude pride because they've given up, but don't want to feel like a failure.

I totally agree. What I'm saying is I'd love to read a more nuanced piece exploring this attitude including its causes and effects.

aganders3··on “You're not allowed science any more”
I agree, but consider that it's on Nature.com and the expected audience. This was an entertaining read for those who have felt such frustration, but it's ultimately unhelpful as a published article.

I did appreciate the point about being proud to be bad at math. I think that attitude is damaging and probably deserves a (more reasoned) article of its own.

aganders3··on The New Airbnb
I agree, but I could see (for example) my parents trusting the new design more. It seems more like a legitimate short term rental service rather than a couchsurfing site.
aganders3··on Tech Blogger Tries To Cancel Comcast Service, Hilarity Ensues
Usually they are recording the call anyway (or reserving the right to). A robot normally mentions it at the beginning of the call. I'm no lawyer, but maybe this is enough to give you permission to record your own copy?
aganders3··on Python is now the most popular introductory language at top U.S. universities
I had a course kind of like this. My intro CS class was taught in Java, and the following summer or semester I took a 1-credit course called something like "C (and C++) for Java Programmers".
aganders3··on Retraction of 60 articles implicated in a peer review and citation ring
This definitely happens, but often you're asked to review a paper _because_ of your experience or publication record in that area. If someone neglects to cite your related work, should you just let that slide?
aganders3··on Alzheimer's research in ‘major step’ towards blood test
At the very least, earlier diagnosis will help the ongoing research into the disease. Even if it doesn't directly benefit this generation of patients, their study may lead to new treatments for the next generation.
aganders3··on Why Bikes Make Smart People Say Dumb Things
I agree, but peds who never ride bikes don't realize this and I don't think you can expect them to. They're used to interacting with cars, where there's not enough room for both (a car and a ped) in an intersection, so their reaction is to avoid sharing it.
