PacifyFish··on Ask HN: Resources to start learning about quantum computing?
I've found Anastasia Marchenkova's blog posts easy to read and thorough https://www.amarchenkova.com/category/quantum-computing/

I like her because she writes code for a living AND has worked at quantum computing startups, and went to postgrad for quantum, so she can go really deep on both areas and their intersection.

She's also on Twitter https://twitter.com/amarchenkova

PacifyFish··on Ask HN: I want to quit coding professionally but keep it as hobby. What now?
I made the switch over to “customer facing tech savvy person.” Think Sales Engineer, Solutions Architect, Technical Account Manager.

Pays slightly less (until you get 5+ years experience, then tends to catch up if you’re good) but my lord it’s so much less taxing on your brain.

You’ll realize that most customer facing folks may be charismatic, but they aren’t very organized or willing to learn on the job. It’s easy to be top 1% while coming in at 9 and leaving at 5, with plenty of time and mental energy leftover for whatever hobbies you want to pursue. Including programming.

Worth checking out if you feel comfortable communicating verbally for a living.

The Wikipedia article states that it’s a cover for a hat, not meant to be worn.
PacifyFish··on Habits of High-Functioning Teams
Psychological safety is 10% job security and 90% how comfortable you feel with the people you work with. Simple to understand, hard to make happen - you need to hire well.

How do you manage dev vs prod instances with sequelize? Specifically, do you use migrations for your local dB or just force sync it?
PacifyFish··on Bolsonaro fires health minister, calls to reopen economy
Keep in mind the lockdown is meant to slow spread so the healthcare system doesn't get overloaded, not to stop it.

It is successful in this respect, and IMO a healthy balance of economic slowdown and death toll. We'll probably start reopening (hopefully in stages, so we can monitor impact) in the next ~3 weeks.

PacifyFish··on Now I understand why almost no one uses encrypted email
I consulted for a company named FlowCrypt last year. Best email encryption UX of any I've seen. Open source and free-for-most business model.

Highly recommend for personal use.

PacifyFish··on Robinhood’s third outage may point to deeper problems in its tech stack
At the volume and frequency they need to process, it probably makes sense to do something more complicated than MySQL...

PacifyFish··on Gitlab cancels plan on tracking user behavior on GitLab.com
Maybe I've missed the boat, but what's the big deal about collecting telemetry?

You already trust Gitlab with everything you store in Gitlab, like source code, which is presumably much more sensitive than the number of times you loaded a page or clicked on a button or whatever.

Is it because the data would be stored with a third party, and you don't trust that third party? If Gitlab trusts the third party, and they're giving you the option to NOT trust the third party and only trust Gitlab, what's the issue?

PacifyFish··on Losing Confidence in Quality: Unspoken Evolution of Computer Vision Services
Why not do a slow rollout, starting at maybe 5% of product. Then you can catch and fix deficiencies without compromising your entire production line, and ratchet up to 10, 15, ... 100% as you gain confidence in the model?

PacifyFish··on No Great Technological Stagnation (2016)
I’ll offer some speculation with no data to back it up: quality of life is good enough that after a certain threshold of wealth people aren’t willing to work extra hours any more. See: Europe & bigco tech jobs.
PacifyFish··on Show HN: Open startups with their revenue, metrics, and stories
Love this site! Did you use a front end framework/template to design it? It’s so slick.
PacifyFish··on Using spaced repetition systems to see through a piece of mathematics
Sure thing.

I’ll typically make a few cards at first trying to test different aspects of the MM (general concept, example applications, given definition identify the MM, quiz any internal associations I have with it like if I learned it in a specific context, etc.) then I can delete ones that aren’t useful and/or add others later.

Let’s use the mental model of inversion as an example. I found this one in a Farnam Street blog post about Charlie Munger. Here are some cards I might create:

Front - what is the principle of inversion?

Back - when you want to try to maximize something, instead try minimizing its converse. Or vice-versa.

Front - what mental model might help if you’ve unsuccessfully tried implementing programs to increase innovation in your company?

Back - inversion. Rather than thinking of ways to increase innovation, can you instead think of things that are decreasing innovation and eliminate those?

Front - what’s another way to think about reducing time spent on work tasks?

Back - invert the problem. Try to increase time saved on nonessentials (e.g. laundry service, meal prep, outsourcing)

Front - what’s it called when you work backwards through a problem you’ve already tried to work through forwards?

Back - inversion

Front - what would Charlie Munger ask you if you came to him with a tough optimization problem?

Back - “have you tried inverting it?”

This is a bit contrived, but I hope this gives you a sense of how I think about creating cards for mental models.

PacifyFish··on Using spaced repetition systems to see through a piece of mathematics
I love Michael Nielsen. He's so earnest and thoughtful.

His recent forays into spaced repetition have been an interesting glimpse into his thought process. I am a bit of a spaced rep fanatic, but use it to internalize more general "Mental Models" (a la Farnam Street), useful tidbits e.g. how to horizontally align using flexbox, or surface-level concepts like product management frameworks.

I love the effort Michael puts into grappling with ideas to strengthen his intuition. This is something I'd like to do more of, but feel that few of the ideas in my day-to-day are sufficiently complex (I don't have any use for linear algebra proofs, for example).

Anyways, that's my word salad on Michael Nielsen and spaced repetition.

PacifyFish··on What’s the rush? The power of a slow morning
Curious how you implemented this. I bought a Phillips “sunrise alarm clock” about a year ago, but the light was weak and I didn’t feel a difference at all. Did you hack together something yourself?
PacifyFish··on Ask HN: How do you keep track of your creative thoughts?
Could not agree more with this, especially for creative ideas or knowledge that is most useful when instantly accessible (ie mental models and facts/concepts that help with making decisions when you can’t do a bunch of research beforehand).

To help with this internalization I made a chrome extension that lets you review your ideas using spaced repetition in new browser tabs. Check it out if you’re interested https://chrome.google.com/webstore/detail/forgetmenot/nncbpj...

PacifyFish··on Ask HN: Why are we spending billions on Space Exploration?
Because that's what people with money want to invest in, because there is a potential market for space travel/tourism/mining, and because money isn't always allocated such that the benefit to humanity is maximized.

Note that I personally am fine with billions going into space exploration, and I think it can be worked on in tandem with climate issues. Just trying to address what seems to be the crux of the issue - you're saying "shouldn't we..." whereas the world is saying "this is how things are."

PacifyFish··on Ask HN: Go-to web stack today?
React/node is what I use for side projects.

React is pretty annoying to set up yourself since it needs to be compiled, so use https://github.com/facebook/create-react-app to spin up quickly or just host vanilla html/css/js and slowly transition to react as you please.

Alternatively, I think the React core code can be downloaded on the client via a cdn.

This is so refreshing. Kudos to Dan Abramov for putting countless cases of imposter syndrome to rest, at least temporarily.
PacifyFish··on The Spacing Effect: How to Improve Learning and Maximize Retention
Hm, I'll probably develop mobile before Firefox so FF would be long way out, but not out of the question! You can follow @ForgetMeNotBot on Twitter for (very infrequent) updates.
PacifyFish··on The Spacing Effect: How to Improve Learning and Maximize Retention
I recently built a Chrome extension that encourages you to add anything you don't want to forget (say, insights from a podcast), then quizzes you in your new browser tabs on those chunks of knowledge using spaced repetition.

Check it out if you're interested, would love any feedback! https://chrome.google.com/webstore/detail/forgetmenot/nncbpj...

PacifyFish··on The Spacing Effect: How to Improve Learning and Maximize Retention
I had a similar experience with the cards I had made as an undergrad.

I recently made a Chrome extension that shows cards in new tabs so that I actually review them. Check it out if you're interested, I'd love your feedback https://chrome.google.com/webstore/detail/forgetmenot/nncbpj...

PacifyFish··on The Spacing Effect: How to Improve Learning and Maximize Retention
Spaced repetition is so effective. I'm surprised it's not more ubiquitous.

I recently published a Chrome extension to review knowledge in a new browser tabs after trying and failing to use Anki post-graduation. https://chrome.google.com/webstore/detail/forgetmenot/nncbpj...

Check it out if you have the chance. I'd love some feedback (and for more people to use spaced repetition in their everyday lives)!
