The bar graphs were not designed to compare total amount of lines for each gender/age-range combination. Rather, they're meant to indicate how the percentage of lines for each gender is skewed older for male actors vs younger for female actors.
If they were to determine the length of each bar using amount of lines instead of percentage of lines, all that would be immediately clear is that females have less lines, a fact well established in the rest of the article, and the point would be lost.
Euhh, I'm not sure I understand your use-case, but e-ink displays aren't especially "cheap", or such. They take a noticeable amount of time to update the display, so doing things like typing, or viewing output from top(1) would be less than ideal. (This seems to get better with firmware, and being "smart" about which places of the screen get updated, generally)
The appeal, at least to me, is that they can display information with little energy cost. For example you could have it monitor the system's health and have it update every half an hour, showing graphs and such, and it would be able to do that for a very long time with a smallish battery.
I feel like I'm missing something - why do you need it to run on battery if it's consistently monitoring a specific machine? Isn't their power pretty much anywhere you'd need something like this?
I edited my use-case after he replied - I think he would be A-OK with something that could be reliably powered from a USB port. I don't speak for him, but I think we've chatted on this topic before.
You can power a "Full HD" monitor off USB. These have been around for a while, but it's really fun to see someone set up with dual screens at a coffee shop running on batteries: https://www.asus.com/us/Monitors/MB168BPlus/
I think he is saying that users can't be tracked between page-loads using this method, or your risk sending multiple users the same token. (which is true, at least with this implementation)
The time they spend on the website, latency, etc can all be used to add to a fingerprint, but there isn't something magic that makes this accurate, especially without JavaScript.
Considering the goal, which is stated very clearly in the README that's shown on the project page, that's not an out of line reply. Here's the first two paragraphs.
A completely clean-room implementation of Minecraft beta 1.7.3 (circa September 2011). No decompiled code has been used in the development of this software. This is an implementation - not a clone. TrueCraft is compatible with Minecraft beta 1.7.3 clients and servers.
I miss the old days of Minecraft, when it was a simple game. It was nearly perfect. Most of what Mojang has added since beta 1.7.3 is fluff, life support for a game that was "done" years ago. This is my attempt to get back to the original spirit of Minecraft, before there were things like the End, or all-in-one redstone devices, or village gift shops. A simple sandbox where you can build and explore and fight with your friends. I miss that.
It's been replaced by Service Workers, but those can get reallly hard to deal with if they start caching themselves (!)
Chrome's devtools has ways to delete old service workers and such, but I've found that on Firefox it's next to impossible to debug.
