RoboTeddy··on Signal verification codes delayed after spike in sign-ups
The more people using Signal, the greater the incentive for nation states to break it, the less secure it is (all else equal).

I know the team has a good reputation, but bugs can be incredibly subtle. I hope they can somehow step up audits or security bounties commensurate with the additional usage!

Also it looks like WhatsApp’s privacy policy changed significantly.
RoboTeddy··on SEC Approves NYSE’s Plan for New IPO Alternative
Why do IPOs involve guessing about the eventual price of shares? Aren’t there auction mechanisms that could be employed to smoothly discover the price?
RoboTeddy··on Facebook's attempt to vilify Apple looks like sour grapes
Can someone explain in more granularity why this change would be damaging for Facebook?

Naively, I would assume that after someone logs into the Facebook app, Facebook knows who they are, and thus there would be not much additional benefit to more tracking information.

Is this about being able to track in third-party apps that use the Facebook SDK or run Facebook ads?

RoboTeddy··on When will virtual reality take off? The $100 bet
I strongly suspect that VR will take off once it can pass through facial expressions, gaze, and other body language with high fidelity. At that point it will probably be substantially better than normal videoconference, and will take off extremely quickly (first for business meetings and perhaps social gatherings; then for virtual worlds)
RoboTeddy··on Show HN: Predict a Reddit user's Myers-Briggs type from their profile
I've heard this too, but I'm not sure how it could be true.

What would we hope for from a personality indicator? We'd hope that it would be useful for making predictions.

At an absolute minimum, MBTI could be used to predict the answers people give on an MBTI questionnaire. And what about beyond that? On the basis of someone testing as an I (introvert) vs E (extrovert), we might be able to predict whether someone would feel drained or invigorated after a busy social event. Has there really been work done to show that MBTIs have zero useful predictive value?

I will readily believe that there might be more useful models of personality, and that MBTI is no longer in vogue in psychological literature, and that MBTI was originally motivated on pseudoscientific principles, and that there more principled alternatives — but it doesn't necessarily follow that MBTI cannot be used to make useful predictions.

RoboTeddy··on Ask HN: How do I get out of the procrastination abyss?
My procrastination pretty much went away (!) when I drew a distinction between “good” and “bad” delays.

A delay is in the “good” category if there are specific reasons that it’s likely that there will be another time in the near future which is better than right now.

For example, if the task you’re considering require mental acuity, and you’re really tired, and it’s likely you’ll be less tired tomorrow, then it could be good to delay.

Or, if it’s time to do a chore except you’re in flow and productive, it could be good to delay the chore: it’s likely there’s a time in the near future where you wouldn’t have to give up productivity to complete it.

On the other hand, if there’s unlikely to be a better time in the future, and you should just do it immediately. (This is especially true for tasks that actually become more work to do if you wait.)

Before drawing this distinction, I had thought the way to avoid procrastination was just never to delay. Attempting to live up to that had proven unrealistic/costly, so I would end up delaying a bunch for all sorts of reasons including bad ones.

After I started drawing this distinction, I set about never procrastinating for bad reasons, while often delaying for good ones.

RoboTeddy··on Ask HN: Who is hiring? (June 2020)
Empower | Senior Generalist Software Engineer | Full-time | REMOTE | https://getempower.com

I've been leading product/engineering at Empower, and we're looking for senior generalist engineers to join the fight for democracy and sound leadership in the US!

Empower has been completely taking off in usage, and it's going to power multiple huge national get out the vote efforts. It's a non-profit tool that helps people talk to their friends and family in a way that brings about more civic engagement and voting in battleground states. There are several independently-run random controlled trials of the project showing that the approach works really well for actually getting people to vote.

We're quite shorthanded in comparison to the opportunity in front of us, so joining is an incredibly high-leverage thing to do. We pay quite well despite being a non-profit (150-200k/yr). We have both shorter term (through the election) and permanent positions available.

RoboTeddy··on Ask HN: How to Handle Coronavirus Stress?
My strat so far:

- Limiting myself to news on the topic 1x/day, which is plenty to stay abreast

- Keeping an eye on my thoughts. Is my thinking on the topic productive (e.g., helping me come up with new useful things to do, like helping friends prepare?) or merely repetitive (i.e., a waste of attention?)

- If repetitive, I practice mindfulness by gently noting to myself (not in a self-flagellating way) whenever I'm having thoughts or feelings about coronavirus, and then just refocusing on the thing I intend to be doing.

Also, it's normal to have a period of difficulty when coming to terms with something bad. It can help you be emotionally prepared for what's coming, rather than having to confront it during the crisis.

In case it helps, one thing that Marc Lipsitch (https://twitter.com/mlipsitch) points out is that this pandemic is not an existential threat. It is bad, and it will affect people you know and perhaps you in a bad way, but the world will go on.

Tier 1:

* high-CRI

* high-lumen

* dimmable, and can be set up to turn on slowly in the morning

Tier 2:

* not glary

Tier 3:

* easy to install

* inexpensive

Agreed — if you're strategic about it, you cut in half the space in which the bug could be hiding each time you add a printf and re-execute.

How can they know they capture 99% of such content given that WhatsApp is (if I understand correctly) encrypted fully end to end such that Facebook cannot access the messages passing through it?
RoboTeddy··on Learn Sketch shortcuts interactively
I want apps to progressively train me in their shortcuts.

An app could track which actions I take manually, in order to learn which shortcuts are most valuable to teach me.

Immediately after I manually take a frequent action, it could inform me of the shortcut. Perhaps I can then even undo the action and redo it using the shortcut, to build muscle memory.

Once I've mastered the shortcuts for my most frequent actions, the app could move on to teaching less-frequent ones... perhaps up to some threshold.

RoboTeddy··on Structure and Interpretation of Classical Mechanics (2015)
I love this book! Prior to reading it, I had been getting confused when trying to learn classical mechanics. The book writes out everything explicitly in code, which let me use the software engineering part of my brain, and made everything easy to follow. Apparently I had been being held back by unfamiliarity with math formalisms!

If you're interested in the topic and know how to program, it might be worth a read in case it turns out you're in the same boat.

RoboTeddy··on Ask HN: What books changed the way you think about almost everything?
'The Power Broker' by Robert Caro is ostensibly a biography, but it's actually about how power works. The protagonist starts out employing idealistic methods, but falls flat on his face, and comes to delight in any means of achievement. I found that once I understood the protagonist's raw goal-seeking, and the dynamics that emerge from it, I started to recognize similar dynamics at many levels of society and government.

Barack Obama read it at 22 and said it was mesmerizing and that it shaped how he thinks about politics.

RoboTeddy··on Instacart paying 80 cents an hour because worker received a large tip
(The following is completely predicated on the truth of the report that a customer tipping $x doesn't result in workers' total compensation being increased by $x)

As a YC alum, I'm disgusted to see a YC company behaving like this.

Instacart: It shouldn't have to be said, but you don't cheat your customers and workers. Whatever internal rationalization you've developed for this practice is just that — a rationalization.

Stop cheating people. If your unit economics are so broken that you can't survive without deceiving and cheating people, then shut down instead.

RoboTeddy··on An AI crushed two human pros at StarCraft–but it wasn’t a fair fight
The averaging period doesn't last the whole game: "we set a maximum of 600 APMs over 5 second periods, 400 over 15 second periods, 320 over 30 second periods, and 300 over 60 second period. If the agent issues more actions in such periods, we drop / ignore the actions. These were values taken from human statistics." [1]

I'd be curious about the approach they used to draw from human statistics. It's possible that peaks in the human APM distribution are caused by e.g. holding down keys, resulting in ~2000 APM [2].

RoboTeddy··on The Homeless Crisis Is Getting Worse in America’s Richest Cities
> Any attempt to solve the problem locally in a "humane" way has a high risk of just attracting more folks in the same circumstance to the area.

I thought this too, but it turns out that despite San Francisco's relatively high expenditures on homeless, only 10% of the homeless population was living out of state at the time they became homeless. (http://hsh.sfgov.org/wp-content/uploads/2017/06/2017-SF-Poin...)
