QR codes are much more information-dense than 1D barcodes. Try encoding a string like "The quick brown fox jumps over the lazy dog" (43 ASCII characters) using these tools and seeing how much space they take up: * https:/&#x

This article gets many things wrong. First, I don't understand why they call QR codes "dreaded". They are simply a standard for communication, not unlike writing down an http:// URL in human-readable text. > Do

The new logo thickens the yellow border, and removes fine details such as the yellow line between L and E, and the yellow line within the O. I think in the print world you can assume decent quality like 300 DPI. Whereas the new logo, with i

The name HAT was given by its inventor Edward Sitarski in 1996. It looks like few people are implementing it and/or calling it by a different name. Because of this lack of development, it might not be possible to change the name to a m

Not to say that the MacBook is better, but I found the Surface Book's keyboard to be infuriating: No right Ctrl key (how do you press Ctrl+I/L/M/P?). Fn lock lamp (one more mode to remember). Hard-to-find Home/End k

I am aware of vim, but don't find its working style comfortable. It's true that vim can work well on a plain keyboard without needing arrow keys, Ctrl key, home/end/pgup/pgdn, shift-selecting, mouse, etc. I like bei

Currency denominations (coins and bills) are usually based on numbers like 1, 2, 5, 10, 25, 50, 100, 200, etc. An extreme example is that Japanese yen are denominated as 1, 5, 10, 50, 100, 500, 1000, 2000(uncommon), 5000, 10000. But I notic
