I can never shake off the feeling that statistics is somewhat lacking compared to the rest of "fundamental" sciences. To me it just lacks sort of brutal honesty that is present say in physics. And how come that the math often "looks" scary? To me this also seems intentional, like someone is trying to hide the lack of real content. Honestly, do we really need a whole field to run a curve through a cloud of points? Please, dispute me in comments below, I would really like to be wrong about this.
I want to make simple FDTD mesher, maybe with non rectangular grid. For this I would need ray-object intersections and point to object shortest distance. Thanks for pointing out Embree, I was not familiar with that library.
Is there a blazingly fast library for ray object intersection? Ideally usable from python? As I understand, ShaderToy uses implicit object description, and calculates ray object intersection numerically. It is somewhat of a abuse of OpenGL, since a scene in ShaderToy only has 2 triangles covering the screen, and the rest is calculated using pixel shader which calculates ray object intersections. I would like to have result of this intermediate calculation (point of ray object intersection).
What can an ordinary person do? Plugging out the network cable? What about laptops? Can this vulnerability hack into Wi-Fi and allow itself to the internet? But then again the moment you plug internet back in you're done.
This reminds me once again how much of our reality is in the brain. So, if you "think" you hear voices - you do, if you think the thing you hear are just your thoughts running wild - you do that and act accordingly. I guess in the first case you would be terrified (after all you hear voices) and in the second case you could be amazed (what a cool thing your brain is since it can imagine voices, "their" thoughts, etc.) How much of the bad things in this world and in life come from wrong perspective... :(
But it is somewhat dishonest. You could color the lines in the same color as the background and then you would have "illusion" of dissapearing lines, right?
This seems not to be due to curvature but due to color distribution of lines. I wonder if effect would still be visible if all lines had same color distribution.
Now this is an ideal crowd and topic to ask a question that is niggling me for a long time. What paper could you use with regular laser printers to get professionally looking printed book? The regular A4 is just too thick, and books printed this way look clumsy.
Is there a calculus based approach to statistics? Like understanding linear regression simply as a minimization problem, but ALL THE WAY ie extending to other statistical techniques?
This is so sad. Every time I read something like this a naive question appears in my head: "Why can't people just get along?". Because in the end it comes down to this: "we" against "them", where "we" have the licence or some other bureaucratic nonsense, and "they" don't.
I love this snippet from Dr Gabor Mate [1], where he talks about "the myth of normal". If you haven't seen this, please take a look, it is truly wonderful.
The knowledge presented in the slides will advance where you are going with your programming in the same way as knowing from which wood chess board is made will improve your ELO rating. Although learning about wood may be more worthwhile goal then learning about topics in these slides.
What is this hoping to accomplish? To convince candidates that they can't print a number? Maybe instead of intimidating people they should be inspiring them?
Are there some examples of Auto-Tune used with more subtle settings? Famous Cher song used it at setting 0, robotic sounding one, but there are 10 more to go, and they are increasingly more subtle.
Also related to this, at least I think, is the issue of turning recording into midi or sheet music. Now that would be a killer app... There is some good software out there, such as Melodyne, but it requires a lot of manual work and tweaking.
Not necessarily, what if it is long term effect? What if it is some kind of resonance involved, i.e. it only shows it face when there is certain geometry and frequency present? Plus there were some courts rulings about phones causing cancer ... [1]
Are you suggesting that microwave oven doesn't work because it doesn't use ionizing radiation? Nonionizing radiation CAN have effects on humans, and current regulations are only based on temperature effects i.e a proxy like a SAR value. But there can be many effects of nonionizing radiation even before it raises tissue temperature level.
I wonder what occasional socially accepted sleep deprivation (staying out late, working long hours, making love all night ^^ ) does to a body. The day after does typically feel like part of you died, and that dead part has to go to work anyway.
- 'journalist' while article says 'an enlisted man in the U.S. Army’s 173rd Airborne Brigade'
- 'just for the kicks' was sense I got from this paragraph of the article: 'Hensinger, sensing an opportunity, stuffed his Nikon camera, ...' and 'He timed his appearance for guard duty to make sure that he would be assigned to the watch tower with the widest view of the mountain and base.'
- Suffering is to some extent measure of morality. For example, recent US military operations heavily used drones. It is one thing to fly drone using XBox gamepad and kill for <insert noble cause here>, and another to shoot soldiers who invaded your country using some primitive gun. First is more similar to video game than to war. Second is more moral, and includes more suffering, no matter what mental acrobatics you use against it.
You are right, it is important to have documents. The soldier obviously had passion for photography, judging by the aesthetics of the photos. I just got irritated by the asymmetry of the situation.
Just found interesting comment from Jack Ma, about US strategy. He said that US had excellent strategy of focusing on IP and design while moving manufacturing and services to other countries. Large amounts of profits were generated, and then squandered on wars (instead of infrastructure). And then there was a nice analogy, in comments sections of the interview:
"When I was 12, I made 100 dollars during a summer job we all used to do, I saved 71 dollars throughout the year and then bought fireworks and spent pretty much all of the money on 4th of July. I think our government is doing the same at a larger scale."
The tone of the article, and the actions of main protagonist, makes a disturbing picture of war. In this setting war is fun for one side (protagonist is taking photos! just for the kicks) and life-death situation for other side. Who is the bad guy here?
I think this project would gain much more traction if it was simple to integrate it within jupyter notebooks. Currently, it is possible, but FreeCAD window pops out outside of browser, or if it is inside the browser the scene is static (no interaction, selecting, zooming etc.) Anybody here knows solution to this?
Is there some nice explanation of how the projections between various EPSG codes work? I converted one projection into another but in QGIS or in python pyproj, but except for the very basics I have no idea what is going on.
Is this true? I once heard that carbonated water is bad for liver, but never found facts to support this (until this paper). Can someone more knowledgeable please comment? People may be destroying their liver and thinking they are doing something good for their health by drinking mineral (carbonated) water...
I think that such wide popularity of internet is driven by illegal content (music, tv shows, movies, books, etc). At least that is one of the rare thing that have some value on the internet. If you take away that, what is left? Cat memes, and fake Facebook friends?
That sounds really impressive. I jumped to comment before reading the paper. I found a nice gem in David Tongs lectures [1] in chapter about Dimensional analysis. He mentions Planck legnth Lp ~ 10^-35m, for which "All indications are that this is the shortest distance scale
possible; at distances shorter than Lp, space itself is likely to have no meaning". So 10^-70 sounds like a nice margin.
I wonder how can authors claim such great certainty in their results, after all, it is all based on number crunching. Some floating point error, and similar is bound to creep in...
