I read the article, thank you. It's you who have misread my comment. I was praising the article for illustrating good principles of visual communication, and lamenting how there are so many people making data visualizations out there that don't understand this stuff.

P.S. From the HN guidelines (https://news.ycombinator.com/newsguidelines.html):

> Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith... Please don't comment on whether someone read an article.

Hence my first sentence, "It seems like you are complaining about graphics in the article, but I'm not sure."

First you said, "I can't count the number of times I've looked at a data visualization and wished I could sit down with the person who made it and read an Edward Tufte book to them."

I was and am 100% on board with this comment. I think the same thing often.

Then you said "There's just so few good examples out there of data visualizations that respect basic principles of visual communication, like the ones outlined in this article."

I agree, the article does a pretty good job.

Then, "They generally seem to aim more for visual impact (like the useless 3D display in the article, which you've gotta admit is striking) than for clarity, which I guess is understandable but is still too bad."

I was uncertain about this statement. The previous sentence you start by stating "There's just so few good examples..." and end with "...like the ones outline in this article", which made it a little unclear if the one's in the article were good or not, but as I was reading it I was leaning to the good side. Then this sentence started with "They generally seem...", and since the end of the previous sentence ended talking about the "ones outlined in the article", I associated "They" with "the ones in the article". And this sentence that started with "They generally" was negative.

Then I contributed some miscommunication. When I used "you" in the sentence I was thinking in general terms (including myself) and not you personally. I think that might have been better stated as "If one reads the article...".

Anyway, I was initially confused by your statement. Now I see what you were going for.

Edits: grammar, missing words

(And as long as I'm griping, don't get me started on all the people who think a wall of text slapped into a PNG constitutes an "infographic.")

It seems like you are complaining about graphics in the article, but I'm not sure. If you read the article, it specifically talks about why those are not good visualizations and gives pointers on developing good ones.

For the 3D one specifically, right under the graphic, the article says: "3D has a time and a place. It can be a really useful way to encode thematic data on the z-axis and make something useful. But extruding Hubei compared to the rest of the areas just doesn’t work. It’s gratuitous and adds nothing. It’s really hard to make any sense of relative amounts and that’s before we even deal with foreshortening and occlusion."

The end result reminds me of Julia. Enough to make me wonder if there's something like it underneath Julia somewhere, or if that's how it started (unfortunately I don't have time to really dig in to it right now).

tinco · 6 years ago
Is there a specific reason we're still doing ground based astronomy? With satellites becoming ever cheaper, sure we at some point should be able to get a significant telescope up there right? Are we waiting for the bigger rockets to accomplish that?
ubertakter · 6 years ago
Yeah. Depending on the spectrum, the telescope might need to be really big. Not to mention at the moment a telescope in orbit would hard, if not impossible, to service.

Perhaps a review of telescope design is in order: https://en.wikipedia.org/wiki/Telescopehttps://en.wikipedia.org/wiki/Optical_telescope

Building large telescopes is hard enough. Putting them in orbit just adds to all the costs. Look at the James Webb Telescope (which still hasn't been launched). https://en.wikipedia.org/wiki/James_Webb_Space_Telescope

It seems possible to launch multiple small telescopes and operate them as one large scope using aperture synthesis. I don't know if there are any existing designs or plans for this.

Also: somewhat ninja'd, see other replies as well.

Julia. Not exactly Lisp, but the concepts are there. Plays well with Python.

I've been learning and using Julia the last few weeks (coming from an OOP background). I highly recommend it. I mainly write highly mathematical programs and utilities to process some data or another. So far I've knocked out some smaller programs and started translating a larger library to learn about the type system. I haven't dug in to UI bindings yet.

I felt this right up until I have a kid. I'm like a mopey teenager again. Movies and tv regularly make me tear up etc. I feel the overwhelming rush and excitement I used to get from travel or goal achievement all over. I think the phenomenon that you're describing is basically we get used to the way things are so the emotional highs and lows are sort of expected. When we're young everything is new. It takes a big change and breaking your pattern to get out of that.

Whew, glad it's not just me. Agree 100%. Although I had some minor underlying issues that seemed to make it worse (better now though).

Now it's not the sundials, it's the smartphones. When was the last time anyone left their home without their phone? (And when you accidentally do, you feel something terrible could happen!)

This "always knowing" (the time, the weather, one's email, the status of one's friends, and so on) must be some mental burden. I think like any other information pusher, it presses against the natural tendency of the mind to wander and to spontaneously create.

This reminds me of a saying I picked up from some (very much) older engineer: Segal's Law: A man with one watch knows what time it is. A man with two watches is never sure.

I feel like information overload is like this sometimes. Which is probably why I try to reduce information that shows up automatically on my phone...

I really try to live up this mindset but I find it very different.

The crucial thing really is that as a child everyone else is in the same boat.

As an adult? Pretty much all of my friends are either at work or plan their calendars to the gills. Even if you try, I'm not sure you can 'go back', unfortunately.

I can't remember the last time I was able to call someone and say 'yo, wanna do X?' and they actually could without advance planning.

ubertakter · 6 years ago
Take a cue from what my friends and I do: we generally agree to do whatever in general terms, say, visit a place Saturday after lunch. That's it. We might coordinate on a start time, but after that, it's whatever we feel like, no set schedule. We occasionally do this for longer trips, where we rent a cabin somewhere for a few days and then just do whatever we feel like. There's some planning involved in order to get to the correct area with the correct equipment (whatever is needed for the activity), but there's no strict timeline.

By the way, my wife is a "planner", so this drivers her crazy, not that she is going with us anyway. So a conversation might be like this: Wife:"What time are you going to the brewery?" Me:"Eh, after lunch" Wife:"So what time?" Me:"Maybe 1300?" Wife:"After that?" Me:"We'll get dinner somewhere" Wife:"Where? When?" Me:"Somewhere, whenever we get hungry. We'll decide on-the-fly." Wife:"Arrrggghhh!!" I have to confess I get a lot of amusement out of her reactions.

I always wonder why Qt5+/Qml/QtQuick have not taken the XP desktop development by storm. QML is JS like, there's an IDE and KDE seems to have built lot of good looking desktop software using Kirigami/QtQuick.

It's got to be better than anything Electron for sure.

Anyone know if .NET Core Qt bindings are a technical possibility?

Two replies mention licensing, with two different answers (It's easy, people just don't understand! It's hard, people just don't understand!). Personally, I've tried a couple of times to read the license information on the Qt site and sort out how the licensing really works. I still only have a rough understanding. It seems like information on the Qt site is intentionally vague so you'll be more inclined to buy a commercial license just to feel "safe" using it. Unfortunately, any commercial projects I work on can't justify the commercial license price.

Anyway, the point is, people may not want to use Qt without being absolutely certain about how the licensing works and they (like me) probably don't have the time to try to understand the poorly organized information on the Qt site.
