| Posted: 27 Feb 2018 04:11 PM PST I was just thinking about this. Since 1 yen is ~0.009 USD, it doesn't really make sense to consider fractions of a yen for most financial calculations, so fixed or floating point math is rather superfluous, isn't it? Do most financial calculations in Japan just use integers, then? I imagine that makes it a lot faster and more efficient at least on most conventional CPUs. Percents can be translated to rationals which can be done entirely with integer math as well. And the largest useful numbers of currency can easily fit in 64-bit integers. [link] [comments]  |
| What are some niche areas of computer science? Posted: 28 Feb 2018 04:18 AM PST Thinking of taking a masters degree and would like to take it in some niche areas (like IoT/Machine-Learning for example). Was wondering if there are something else or newer. [link] [comments]  |
| What are the things I need to know by the end of an Introduction to Unix course? Posted: 27 Feb 2018 09:24 PM PST Our teacher is wildly in incompetent and I don't do well studying by myself unless I have set goals. I could probably pass the tests but I'd like to actually know the stuff, so I'd appreciate any advice. [link] [comments]  |

| What is the simplest way to recover the original time series from a moving average feed? Posted: 27 Feb 2018 10:25 AM PST Considering a simple moving average (say with window of 5) is a convolution (with [1 1 1 1 1]), what is a simple way/algorithm to deconvolve that etc to recover the original time series? For practical case, lets say we get hourly data feed of last 24-hr simple moving average and we'd like to recover the hourly data (which we otherwise dont have access to) [link] [comments]  |
| Need an advice which study Programm offers a better future Posted: 27 Feb 2018 05:59 PM PST Hi guys, it's probably a trivial question. I struggled a lot in finding what is the right thing to study for myself. My biggest wish was to study medicine, but in Germany it's really hard to get the opportunity if you don't have incredible marks. So I studied biology, but I didn't enjoyed it because if you want to be successfull in biology you have to do one PH.D. So I decided to study a thing which I'm good in, Computer science. I studied economic computer science for four semesters. I enjoyed it but my buddies were really lazy, so that I actually struggled to take all the courses (sadly). So I decided to change and began to study biological computer science, which I enjoyed as well. I got the bachelor of science last January. Now I have to decide which Master of science will follow. I thought about a master in biological computer science, but I'm scared that I'm limited in working in the pharmaceutical industry, which is actually nice, but limited. And my experience so far was that for biologists you are nothing but IT nerd who actually don't have a clue how the 'real biology' works. So my thoughts were to end my university career, which is a sad career so far since I changed too much the study program, either in master of economical computer science, cause in Frankfort, Germany I find easily a job and they pay good or in master of biological computer science. But I'm scared that another change looks awful on my already awful looking curriculum. I hope you get what my problem is, sometimes talking to strangers can help. Thank you very much!

| Resources / Direction for Drone Project? Posted: 27 Feb 2018 03:43 PM PST NO hardware or code; I'm purely interested in the math and theory necessary to manipulate a quadcopter / automated airborne drone. I'm aware that this will likely require some form of elementary control theory, as information from the sensors must influence the stabilization mechanism (propeller / fins), which will in turn change the input to the sensors. I'm assuming differential equations will be necessary as well. Eventually, everything would be implemented on board a micro controller. I believe I have the programming skills necessary, but I have zero clue where to start otherwise. Has anyone done a similar project, or know what I should learn and where I could learn it? Perhaps a book, or a web series? [link] [comments]  |
| For a database: How do I synthesize a lossless and dependency-preserving decomposition of T in 3NF? Posted: 27 Feb 2018 05:58 AM PST Hello! I am working on an assignment for databases in SQL, and one of the questions is "Synthesize a lossless and dependency-preserving decomposition of T in 3NF". What is a 3NF decomposition, when is it lossless, and when is it dependency preserving? e: For refference, here is T: T = {Product (P), Category (C), Designer (DE), Price (PR), Season (S), Year (Y), ProductionCycle (PC), Facility (F), Department (D), Group (G), SaleUnits (SU)}. And the minimal cover of T: {{DE} → {G}, {P} → {C}, {P} → {DE}, {C} → {PR}, {G, C} → {DE}, {P, D, S, Y} → {F}, {P, D, S, Y} → {PC}, {P, D, S, Y} → {SU}, {F, PC, S, Y} → {P}, {F, PC, S, Y} → {D}} [link] [comments]  |
