Is the creator thinking of doing another printing? If not can someone recommend a service that will print a high quality card deck given the PDF?

A cheap laser engraver could work well here.

Would you need 2layered paper, with a different color underneath? Or would engraving the words directly onto card stock be legible?

Can you give a visual example where they're not? (other than anti-aliasing round the edges)

See https://medium.com/alex-couch-s-portfolio/type-hierarchy-and... for some of them. The “blurry eye test” mentioned there is related to the typographical term of color (see https://bigelowandholmes.typepad.com/bigelow-holmes/2015/04/... and https://practicaltypography.com/color.html ) which is affected, among other things, by the actual shape of the glyphs.

I see. You're clearly knowledgeable in this area and my naively used terminology has misled you. In terms of contrast I'm talking about the simple stuff "Contrast is the difference in luminance..." https://en.wikipedia.org/wiki/Contrast_(vision) whereas you're talking of something typographical I was unaware of. Sorry for the confusion.

To be fair, though, the first comment that referred to contrast was clearly talking only about color, and had nothing to do with "topography contrast."

The original comment was

> Designers love grey on grey. I’ll take comic sans any day.

These are two orthogonal features. It's like saying "fashion today is really into high waists, but I'll take denim any day."

> the first comment (…) was clearly talking only about color

That comment explicitly mentions a typeface (Comic Sans).

I print with some professional card printing companies, the pricing goes something like 10 decks, 500$, 50 decks 800$, 100 decks 1200$, and 300 decks 1500$ and then it continues to drop Since I printed only 50, I think the price is too high, so I would rather to give them for free than to charge unreasonable price. If you are willing to pay the shipping cost send me an email to b0000@fastmail.com, I still have few le…

You can get the 50 deck rate for even a single deck (and there are often coupon codes) at https://www.printerstudio.com/unique-ideas/blank-playing-car... or https://www.artscow.com/photo-gifts/playingcards

Also, if you're trying to give this away, they both allow you to share a link to your design so other people can buy the cards direct.

edit: the sites may seem cheezy, but they're probably responsible for 95% of prototype card decks that professional designers print.

For other excellent non-Chinese, Buy America options, there are https://www.printplaygames.com/product-category/prototypes/c... , https://www.thegamecrafter.com/make/pricing#Cards and https://www.drivethrucards.com/joincards.php

There's a typo on the instructions page. The example has 'rises' but the rest of the explanation uses 'raises'

I love this as a concept, though.

I think if I were to expand this I'd maybe have pre-defined strings for the greps, cards with results on, number pre-selected etc. This makes it more of a 'find the card' or 'matching' game than a problem solving game, but it would make it more kids-card-gamey

I love Unix pipes and I love the immense computational power you can achieve through streaming pipelines. You hear stories of people processing terabytes of data faster and cheaper than a distributed cloud solution, by the virtue of Unix pies[1]. But I don’t really see them in any other environment. I can’t think of anything that uses something similar except for big, distributed data processing pipelines like Apache…

This is one of the things that I think Perl (still) does really well. It has flags to allow for command-like one liners and has built in things (like the diamond operator) that make it very quick and easy to write 'filter' scripts that read STDIN and print to STDOUT.

Python can do these things, but they aren't very pythonic and they don't feel as natural/intuitive.

Sorry for the confusion.

In the end, font contrast also involves the simple stuff, but the difference in perceived luminance depends on more than just foreground and background colors.

They’re not. The people asking for specific font faces for brand or accessibility reasons are the same people who design apps and websites with text I can’t read.

In this case, click the post link. It’s black text on a white background. Comic sans would work fine, and it would be better than a monospaced font added for some nostalgia for a time when fonts could not be kerned.

The photo at the bottom appears to be some small ergonomic keyboard (maybe an Atreus?) built into stained wood along with a screen. Perhaps it is a cyberdeck? Curious to know more.

Ah! I didnt mean to show it off, just my desk is a mess.. Yea its a cyberdeck I am building with hardwired Atreus directly connected to pi zero gpios and using libuinput to make a software keyboard, which works amazing btw. I am making it to init directly into getty without login (with busybox init), so it boots directly in usable /bin/bash in only 2-3 seconds, and all the available programs are simple python program…

>And I am trying to make it like a 'scavenger hunt' experience for my daughter, I will put special codes in various places in the programs or on the file system with different difficulty, and I can challenge her to find them.

This is brilliant. I really admire the lengths you go to so that your kids can be engaged. Sounds like this has the potential to be quite fun and exciting.
