jonahss··on Show HN: Trading cards made with e-ink displays
Ah thanks, I worked hard on the contacts.

There's a thin and flexible e-ink display I could use instead, but they're $20 each instead of $4. I agree they're a bit chunky in this form :)

I agree the docking station detracts a bit from the naturalness of just playing on a table.

I decided to build what middle-school-me would have wanted to play with. I took a lot of inspiration from Yu-Gi-Oh which has the same docking station concept (just executed much better, where you wear it on your wrist).

Oh hey, I've been looking for small demo games to implement on it, before jumping into a massive RPG or something. I can try implementing that.
jonahss··on Show HN: Trading cards made with e-ink displays
Thanks! Yeah me too! I've got an idea for a game, but I'm not an experienced game designer. If others want to try to design a game for it, I'd be open to sharing with them :D

Mostly wanted to inspire something new.

jonahss··on YKK zippers: Why so many designers use them (2012)
I heartily recommend stopping by their headquarters in Tokyo, they have a small museum open to the public! Their largest zipper has fist-sized teeth and is for zipping together fishing nets.

Look for the YKK letters on a building near Akihabara.

My friend’s father is a firmware engineer in Bulgaria and he hadn’t even heard of Rust. I’ve noticed that it takes a looong time for technologies to propagate globally

jonahss··on S&P Dow Jones Indices to launch cryptocurrency indexes in 2021
The "anywhere in the world" part is really huge. As of now, most cryptocurrencies aren't run by nation states, unlike traditional currencies. Cryptocurrencies have to potential to become a global currency that's fair to all.

I actually think that the nation states really missed out when they didn't mint their own cryptocurrency that has the same value as their physical money. If they controlled a currency completely, they could tax every transaction! Surprised they didn't jump on this.

jonahss··on S&P Dow Jones Indices to launch cryptocurrency indexes in 2021
There's a few cryptocurrency index funds already, where the fund itself is completely automated and shares of the index are tokens on an ethereum contract. So you buy in with ethereum, then can liquidate you shares back to ethereum whenever you want. Still relies on a real-world organization, but pretty cool.

jonahss··on Photos from inside a Typhoon class submarine
Zeppelins like the Graff and Hindenburg had machine shops onboard as well!

Their engines were very unreliable, they could do overhauls mid-flight. Airplanes around that time were just as unreliable, but flew shorter hops. Had to overhaul or swap their engines quite regularly between flights.

jonahss··on How I bypassed Cloudflare's SQL Injection filter
Ran into a funny bug once from either Cloudflare or AWS's implementation of a similar service.

Marketing made a big push for a new Promo code on the site we were running, but the promo code wasn't working. Reports came in that the promo code worked if you entered it as lowercase, rather than all caps.

Double-checked a dozen times, we take whatever string the user passes in an converted it to upper case, and all the values in the db were upper case. Keep thinking we must have messed this up somewhere.

In the end, the devops guy realizes that AWS (or Cloudflare, I forget) was blocking the uppercase requests, since the promo code was `SELECT` >.<

Assumed it was an injection attack, but only when uppercase.

jonahss··on Experimental evidence of massive-scale emotional contagion thru social networks (2014)
Are studies of this sort still being done, perhaps privately at Fb or other social networks?

This study was unethical, and revealed something very scary about the potential of social networking, but I haven't heard much since then. Did they stop all research into social behavior, find ethical ways to do it, or just stop publishing publicly?

jonahss··on The Third Age of JavaScript
maybe.

but also, there’s a classic pattern of articles which look back and describe a timeline of “past, present, future” where future starts tomorrow due to this thing I’m excited about today.

jonahss··on How I survived being a $220k/year intern
Adding another anecdote, I worked for a company which paid Glassdoor to remove a bunch of negative reviews. The score jumped from 2 to 4 overnight and a bunch of well-written negative reviews disappeared.
jonahss··on AB2712 – California Universal Basic Income
My read on the exclusions is that UBI as a form of welfare solves an issue all our other welfare programs have: attempting to apply credits to very specific costs instead of eliminating loads of administrative overhead and terrible paperwork by just giving people money to spend on what they actually need. cash instead of a giant coupon book which doesnt cover edgecases.

So I could understand if they want to try to replace existing welfare programs with UBI and then ratchet up the UBI amount until its better than the old programs (and more flexible).

But as-is, yeah, this doesnt help some of the ppl who need it most

The author seems to do a lot of unusual and roundabout things with the software on their personal mac. It's cool to see somebody fully exploring personal software and customization, but what they're doing sounds weird to me.

From another post[0] on their blog:

>You’ll be able to upgrade to version 2.0 for a one-time purchase of $6.99 – no subscriptions here!

No subscriptions here, just me rewriting the app and deciding to charge for the new version every so often.

What is a "well-established startup"?
jonahss··on Introducing nushell
Love it! Thanks. I've always thought powershell was a great concept, badly executed (those long names with capital letters, confusing errors, and insanely long time to return when a command is missing).

Is anyone interested in a shell with a GUI? As in, data still passing as text, but having a shell which can render textual data into widgets when displayed in the shell?

jonahss··on Tourism Is Overwhelming the World's Top Destinations
This is a good sign of travel and leisure being affordable for an increasing percentage of the global population. Regrettable for current tourist destinations that aren’t set up for the scale, but we should be happy that so many people from so many places are free to travel

really great!
jonahss··on The Spanish Prisoner: On the Future of Libra and Bitcoin
I agree, the article gradually became more incomprehensible but the core point seems to be that the author has realized that mainstream currency will become crypto with government/corporate backing and lose the anonymity.

which is true. It couldn’t have gone any other way, realistically.

I’ve made my peace with it, at least the we keep making tiny steps forward. It sure beats the credit card networks and paypal.

jonahss··on Prospecting for gold by looking in leaves has proven itself in Australia
I'm disappointed they collected the leaves by hand. I thought the article was going to say they can measure the gold-content in leaves using drone imagery
