cypherpunks01··on Storing binary data in playing cards (2014)
It's always been pretty mind-blowing to me that you can store over 225 bits of information just in an ordering of one deck of cards. A standard way to store data in this way is a factoradic encoding like Lehmer coding:

https://en.wikipedia.org/wiki/Lehmer_code

The python library 'permutation' has some functionality around this that's fun to play with:

https://permutation.readthedocs.io/en/stable/#permutation.Pe...

I found new joy in shuffling a deck of cards, after learning that every (proper) shuffle that every human's ever done has returned a unique deck that nobody's ever held before.

edit: I just remembered a guy who made a javascript demo that encodes small strings into a card deck order: https://jerde.net/peter/cards/cards.html (explanation page linked)

cypherpunks01··on Joplin is an open source note-taking app
My only concerns about using Joplin were security-related, when handling sensitive notes (financial data, logins, etc). The interface looked awesome.

Have Joplin plugins been secured/sandboxed yet, or are they still able to exfiltrate data? That's one reason I never used it for very secure notes, same with Obsidian. Joplin also used to store notes unencrypted locally, not sure if that's still the case. Of course most people don't mind, but I was investigating the highest-security note tool I could find at the time.

cypherpunks01··on Alcohol-Related Deaths Surge to Nearly 500 a Day, CDC Says
Original source:

Deaths from Excessive Alcohol Use — United States, 2016–2021 from CDC's Morbidity and Mortality Weekly Report, Vol. 73, No. 8, Feb 29, 2024

cypherpunks01··on Alcohol-Related Deaths Surge to Nearly 500 a Day, CDC Says
- Two thirds of the deaths (about 117,000 deaths) are due to chronic conditions that develop from long-term alcohol use, including various types of cancer, heart disease, liver disease, and alcohol use disorder.

- One third of these deaths (about 61,000 deaths) happen from drinking too much on one occasion, such as from motor vehicle crashes, poisonings involving substances in addition to alcohol, and suicides.

PSA: Authy Desktop is being killed off this year, which could mean the last opportunity to export your tokens out of Authy (for migration, or for external backup)

There are a few gists floating around regarding how to export by remote chrome debugging an older version of Authy desktop app, which still worked for me recently. This page explains too:

cypherpunks01··on British intelligence able to read and flag private Snapchat messages
I thought they might have been talking about reporting a false threat, or something of that nature?

If you are a comedian working on a joke and write one about a political assassination in your private journal, certainly you can't be charged with communicating a threat, because you did not communicate it. But if a friend/enemy finds your notebook, knows you have no intent to harm, but reports the journal to authorities out of spite anyways, then the friend could be culpable for communicating a false threat, even though the joke is in your handwriting. Maybe they were getting at something like that?

In any case, it was very awkward wording at best for a report from Reuters, it should have been either explained or left out.

cypherpunks01··on It was almost impossible to make the blue LED [video]
I thought this was a really well-produced video! It's difficult to communicate science to the public in an accessible way at the right level, and I think Derek does a commendable job.

I really liked the LED explanation at the 4:00 mark. Can anyone who is familiar with semiconductor physics opine on how well this explanation models the reality?

cypherpunks01··on Relativistic Spaceship
Hmm I suppose you're right. I guess you'd see very few transmissions during the journey due to time dilation, and then those 10 years would arrive relatively quickly when slowing/stopping?

I was thinking of this being the first half of the twin paradox, but perhaps for the apparent "time gap" in the spacetime diagram to appear, it's necessary for the traveling twin to turn and head back towards Earth quickly to shift simultaneity plane back in the other direction.

cypherpunks01··on Relativistic Spaceship
I think the perceived output from stationary lasers on Earth would appear to decrease as your speed increases, since you're accelerating away from the laser photon packets. Because of that behavior, I'm not sure it's a feasible way to get up to relativistic speed?

I think the lasers would also need ~10,000 years of fuel, as opposed to ~10 years of fuel if you could somehow figure out how to carry it. But the energy to sustain in either case is probably measured in Dyson spheres, or some fraction of all energy in the universe pretty quickly too.

cypherpunks01··on Relativistic Spaceship
While traveling near c, I believe you'd be receiving Earth transmissions from approximately the same time you left, Earth clocks would appear to slow down to a crawl. But if you land on another planet and change reference frame to be more "stationary" again relative to Earth, I think a massive amount of Earth time would suddenly appear to have elapsed very quickly during the process of slowing/landing because of the huge shift in simultaneity.
cypherpunks01··on Ask HN: When to Start a Business?
It's just spam. There's no way to tell whether a human is involved in the response, or if it's just a bot someone let loose. Anyone who wants a response from an LLM can get it at little/no cost.
cypherpunks01··on Show HN: Lockbox: forward proxy for making third party API calls
I've usually used nginx for this purpose, proxying requests to a 3rd party server but tacking on authorization headers, for example, keeping them secret from the client. This strategy's always works great for me, but I guess it's limited to fairly simple pass-through use cases.

This seems cool if there are more complex needs or configuration that can't be done with simple proxying and nginx rules.

cypherpunks01··on On knowing who he was
A lot of criticism is leveled at Alan Watts, by people who point out how he conveyed many oversimplifications of religious teachings, or ideas that seem to be misunderstandings of teachings from an academic point of view.

I think what those people are either missing or ignoring is that his main motivation was to be a spiritual entertainer, as he described it, and I believe he's best interpreted and understood that way as well.

If people want to learn a rigorous deep understanding of certain philosophies and spiritual beliefs, there are innumerable other ways to dive into this, and better people to listen to. To me, his conveyance of ideas is better suited to impart interesting and different ways of looking at the world in a general manner and to pique one's imagination, not to learn spiritual concepts in a rigorous way.

I always felt he succeeded in that way, simply by attracting more people towards an interest in a spirituality and philosophy, and giving a starting point from which they can pursue serious ideas if their interest is sustained.

cypherpunks01··on Capturing the ripples of spacetime: LISA gets go-ahead
How's this thing powered? Are solar or big RTGs enough? I would think power requirements for these scale lasers, detectors, and transmissions would be pretty large. Isn't it an extraordinary amount of data that needs to be constantly sent back to Earth? I thought LIGO was generating a crazy amount of data per day beyond what I'd think would be possible to stream live back to Earth from so far away.

Also, how can the test masses remain in free fall, while each satellite is undergoing course corrections? Or are corrections infrequent enough for satellites in this earth-following orbit that it wouldn't cause any real amount of downtime? Of course Earth is free-falling.

cypherpunks01··on Mysticism and Empiricism
I see how you find it dystopian to think that people could be given drugs just to keep them placated by inspiring false belief in an afterlife. But I don't think the afterlife belief is actually the main attitude that is driving psychedelic patients to have decreased fear of death.

Check out the 2022 study "Comparison of psychedelic and near-death or other non-ordinary experiences in changing attitudes about death and dying"

https://journals.plos.org/plosone/article?id=10.1371/journal...

Specifically Table 7, which shows changes in attitudes of psychedelic vs non-drug (who had non-drug near-death or other non-ordinary experiences) participants.

It shows changes of certain attitudes towards death between these two groups. There is a large positive change in curiosity about death. The increase in the attitude you mention, the Approach acceptance ("I look forward to life after death") was actually increased more in the non-drug participants who underwent NDE or similar, as compared with psychedelic participants. But a far larger effect in the decrease of avoidance attitudes ("I avoid death thoughts at all costs"), and an even larger effect in simply having a reduced fear of death.

From this, and from personal psychedelic experience, I do not think increased belief in an afterlife is the primary driver of a reduced fear of death following psychedelic experience. I think the attitude change has much more to do with gaining universal acceptance of death as a natural consequence of life.

Did anyone else ever explore the huge multi-level basements of the hotel? In the final sub-basement, I remember there was a passageway that connected into one of the subway tunnels way down there.

cypherpunks01··on Astronomers posit that we live in an area with below average density

cypherpunks01··on Ask HN: Is Unlimited PTO a Scam
It's not exactly a scam, but it is a psychological trick of sorts. Unlimited sounds nice, but, of course, any employee would be fired if they started taking unlimited vacation.

One thing that's rarely mentioned is that for employees who accrue fixed vacation time, the monetary value of this time tends to be legally required in most US states to be paid out upon the employee's termination. I'd guess that with unlimited vacation time, $0 is paid out.

cypherpunks01··on Writing a GPT-4 script to check Wikipedia for the first unused acronym
When this happens, I'll usually say something along the lines of:

"This isn't working and I'd like to start this again with a new ChatGPT conversation. Can you suggest a new improved prompt to complete this task, that takes into account everything we've learned so far?"

It has given me good prompt suggestions that can immediately get a script working on the first try, after a frustrating series of blind spot bugs.
