jamesgreenleaf··on My Tungsten Cube (2019)
Some of the reviews on these are fantastic:

jamesgreenleaf··on Show HN: This Idea Does Not Exist
Yeah, I remember Last.fm being pretty good at that. Also, Pandora seemed like magic back when it first came out.

> A company that turns your Spotify playlists into a radio station that plays similar music based on your tastes.

"It's like Spotify for Spotify."

jamesgreenleaf··on Kid Pix as a JavaScript App
This made me smile. I loved this as a kid.

Next do Spider-man Cartoon Maker ;)

jamesgreenleaf··on Tree Shaking
1. In real life, you shake real trees, to get fresh fruit.

2. In JS, you shake fake trees, to shed bad fruit.

3. Common wisdom says: "Ye shall know them by their fruits."

Therefore, all JS dependency trees are rotten. /s

jamesgreenleaf··on Bezos donates $100M each to CNN contributor Van Jones and chef Jose Andres
The Earth is going to die one day. The Sun will die too. There is no guarantee that intelligent life will survive on this single planet, even if we do a perfect job of taking care of it. Catastrophic, species-killing events can happen at any time. If we wish to ensure the long-term survival of the only intelligent life in the universe that we know about (as well as the survival of all the other creatures on Earth, who don't have our knowledge) then adapting, exploring, and surviving in space is what we must do. It absolutely surprises me that relatively few people seem to understand (or voice) this fact. We may have a long time to accomplish it, but that it should be our primary goal is extremely clear.
jamesgreenleaf··on Software Engineering at Google
I've felt the same way - as though not being able to shoehorn everything into pure unit tests somehow means that I'm not doing testing right. In most cases though, what we really care about is verifying the full functionality of an app. Maybe integration & e2e tests should be considered as the primary form of testing, with unit tests applying only in the specific cases where they make sense, like you mentioned.

Maybe the ulimate form of testing is something along the lines of Netflix's chaos monkey (now apparently an entire "simian army" suite of tools). Continuously test the real application, live in production, where it's not allowed to fail.

jamesgreenleaf··on Must-read psychology books
I'm surprised none of Robert Greene's books are on this list. Maybe they wouldn't be strictly categorized as psychology. The Laws of Human Nature delves into some psychology and personality types though, and is worth reading.
jamesgreenleaf··on The Rule of Three
I noticed this on a box of Diamond Crystal brand kosher salt.

You can tell they were really reaching for that third bullet point to list on the side of the box:

- No Additives (Just Salt!)

- Kosher for Passover

- Sticks to food well

I like to imagine they held a serious design meeting about it.

jamesgreenleaf··on Bitcoin Core: Bitcoin Core 0.21.1 released with Taproot activation code
I would guess that Grayscale and others have thought of that, and have written it into their contracts with customers. I'd also bet they're the ones who pocket the proceeds from any forks.
jamesgreenleaf··on A whale who tried to mimic human speech (2014)
Environmental conditions are a big factor as well. We've existed as humans for ~300k years, but it was only ~10k years ago that we learned agriculture and civilization-building. That coincided with the beginning of the Holocene Epoch, when the world got warmer, the glaciers melted, and the sea level rose by 400 feet. We must have had those capabilities all along, but it was only when the conditions were right that they were able to be fully expressed.

You're right, but in a way that makes the act even worse.

Sounds like Substack for data viz.

What's your pricing structure?

jamesgreenleaf··on Adobe charges subscription cancellation fee
Things like this are a great use-case for privacy.com, or any other service that offers burner cards. Set a monthly limit, or make it one-time, etc. and make sure the company can't charge you more than you've specified.

I'm not affiliated with them, but I'm a fan of their product.

jamesgreenleaf··on Retool – Fixing product debt without PMs
Could you expand on this a little? I'm using Retool now for a client, and while some parts are a little shaky, I can see how it's saved a lot of time over developing internal dashboards from scratch.
jamesgreenleaf··on Staying awake to treat depression (2018)
You can certainly try this method, especially when you're younger, and you'll probably feel exhilarated and your mood will improve... until you finally go to sleep again. The effects don't last very long, and losing sleep continually is very bad for your health.

I would recommend to anyone with depression that you first change your diet. Stop eating refined carbs & processed foods of any kind. Stick to basic fruits & vegetables with some whole grains, and beans for protein. Adapt this as your personal needs vary, and as you see fit. I think you'd probably be amazed how much eating well affects your mood, especially if you've never done it before for any long period of time.

Here's some more info on a good, simple, science-backed diet to follow: https://www.hsph.harvard.edu/nutritionsource/healthy-eating-...

jamesgreenleaf··on Zoomable lens without any moving parts
It's a valid observation. A lens that could somehow do that without moving at all would be pretty magical, and the headline plays on this to get your attention. The headline could have been "MIT Creates Zoomable Lens That Works Using Heat" which is still cool, but not as sensational.
jamesgreenleaf··on Show HN: Places to watch ducks if you're sick of everything
Pretty cool. I like ducks.

One bug: the pin for "The Pond at Central Park" incorrectly shows up near 64th & 1st. Looks like there are some others that aren't accurate too.

jamesgreenleaf··on Amazon loses effort to install camera to watch counting of ballots in union vote
There are a number of ways you can read that tagline.
jamesgreenleaf··on In the deepest despair, electroconvulsive therapy offers hope
Some people in this thread have mentioned that ECT is only considered when doctors have "exhausted all alternatives". Does that include the use of psychedelics? I don't know about you, but before electrocuting my brain I might be willing to try a particular mushroom that humanity has been using for thousands of years to alleviate feelings of despair and meaninglessness, and one which has shown serious promise in that regard in several recent studies. It's really too bad most governments saw fit to make it highly illegal.

Disclaimer: Not for everyone. I am not a doctor. Do not eat fungi you find in the wild unless you are a trained mycologist.

jamesgreenleaf··on A new model for faster-than-light travel that uses conventional physics
Have we truly been ready for any of humanity's technological developments? They tend to be very messy, and lead to all sorts of consequences few could predict.
jamesgreenleaf··on Bitcoin is not a Battery – it is a Sink
Only the extremely wealthy could line their floor with gold. You were comparing Bitcoin to gold, not "all lustrous materials". It remains a poor comparison.
jamesgreenleaf··on Bitcoin is not a Battery – it is a Sink
Aside from its noble properties and industrial uses, gold is a terrifically lustrous metal that most every human being in history has admired and desired. Its ability to convey wealth, luxury, power, and beauty has not diminished for thousands of years.

Bitcoin is a ten year old project, written in mutable code, that's invisible, intangible, and essentially replicable by any number of competing crypto projects or forks. It may be useful, or it may not be. It may stick around, or it may disappear. Either way, it's not seriously comparable to gold.

jamesgreenleaf··on The Revolution in Classic Tetris
No, the wordplay works with variations of the words "for" and "long".

The "furlong" etymologically means a "furrow length" which is what you could call that spot everyone sets up for the narrow tetris block.

jamesgreenleaf··on Facebook freezes Venezuela president Maduro's page over Covid-19
Another problem is that something like this can function as "evidence" for the claim. There are large groups of people who believe that censorship like this validates a worldview in which powerful interests are censoring true information in order to maintain control. It's similar to the Streisand Effect or "Banned in Boston" but for belief rather than attention.

It seems like the better solution is to have an outpouring of discussion around how and why the claim is wrong. Let others ridicule the statements, rather than shutting down discussion. You'll never convince everyone, but at least you'd avoid the validation-by-censorship effect.

I could be wrong on this though. I don't really have any evidence or data that would show doing it one way is better than the other. I suppose I simply prefer open discussion.

jamesgreenleaf··on The Revolution in Classic Tetris
A furlong for a longed-for long-four won't last for long.

> To [hypertap], he developed a unique one-handed grip: with his right thumb on the control pad, he flexed his right bicep until his arm shook, pressing down with each tremor, about fifteen times per second.

Did anyone else do this for other games? I used to pull this move all the time in those mario party style games where you had to be the first to press a button, or had to tap the most in a certain period of time.
