  • Where to start game programming for Android

    - by Marthin
    Hi, I'm new to game programming. But I'v got an ide for what I think would be a fun game for the Android platform. My question is, where do I start? Anyone got some good sites to recommend or perhaps a book or two. I'v got medium skills when it come to programming but i'v got a masters of science degree in computer engineering so i'm not totally unfamiliar with algorithms and stuff. Thx for any help! /Marthin

  • How can I know if programming is right for me?

    - by user66414
    I have an IT background and was pretty confident until an opportunity came up at work to go into programming(C#). I have never programmed before this, and the software I am programming for is a program I have never used before (a 3D modeling software). It has been 6 months since then and I feel like giving up. I didn't get much training... about 3 weeks of training spread out over the last 6 months. I think I would be good at programming but this experience is kinda making me rethink my decision. I'm not sure if it's just me, or if this frustration is normal. How can I tell if programming is right for me?

  • Will Beej's Guide to Network programming point me the right way to be able to make multiplayer games and a web broswer?

    - by Logan545
    I'm new to socket programming in C, and I've found the Beej's Guide to Networking programming. It looks fine and all, however, I just wanted to ask whether this tutorial will point me in the right direction in terms of network programming. I plan to build a game in opengl that will be multiplayer using c+ and possibly a web browser. I know this tutorial would by no means teach me how to do this, but would this be a good way to start off on my path?

  • How do I transition from physics and math to programming?

    - by inovaovao
    I'm a physics PhD with little actual programming experience. I've always liked programming and played around with BASIC, Pascal as a teen, but the extent of my experience writing complex programs comes from an introductory course in computer science. Now I've decided that I'm more interested in programming than in physics and started to learn Java. Coming from a physics or math-heavy background, what would be the best strategy to maximize my value in the field?

  • MapReduce programming system in java-actionscript

    - by eco_bach
    Just finished reading ch23 in the excellent 'Beautiful Code' http://oreilly.com/catalog/9780596510046 on Distributed Programming with MapReduce. I understand that MapReduce is a programming system designed for large-scale data processing problems, but I have a hard time getting my head around the basic examples given and how I might apply them in real world situations. Can someone give a simple example of MapReduce implemented using either java, javascript or actionscript?

  • How to stay connected to the programming community?

    - by Anton
    I often find myself detached from the programming community and I generally find out about all the "cool" things that are happening after they have already happened. So my question is how do you stay connected and up to date with the programming community? Podcasts, blogs, meet ups, conventions, twitter, talking with your co-workers whatever it may be that keeps you connected. Please provide actual examples of which blogs, talks, etc you use.

  • Why should "miter" joints be slower than others?

    - by Hanno Fietz
    I'm having a graphics problem on drawing lines in Flash Player, where two lines drawn on top of each other with different thickness don't align properly if I use any other JointStyle than MITER. For pictures of the effect, and for the graphics oriented part of the question, see my post over on doctype. However, there's also a second angle on this problem, which is: why should drawing the "mitered" joints be so much slower than others? This seems to be a problem since at least FP 8, but I couldn't find any detailed info on what the problem might be. Is this just an ordinary bug that didn't get fixed yet, or is there something inherently slower about drawing these joints? For example, they seem to have something to do with square roots, but I seriously lack understanding of what this joint style thing is all about, technically. It just looks like some minor detail a graphic designer might worry about. I'm asking because I'm wondering if I can do something to mitergate, er, mitigate, the problem.

  • Best programming language for teaching econometrics?

    - by TJB
    I will be teaching an econometrics course to masters students in the fall. I think it is important for them to learn programming with data as an essential applied research skill. What suggestions do you have for the programming language. I am leaning mostly towards R. What others should I consider?

  • Animate a e.Graphics.DrawLine with arrowhead

    - by Fer
    I need to "animate" an arrow. It can go in any direction (up, down, left, right and diagonals) and the arrowhead will be at the end. It needs to appear as if it is growing from orgin to the end. To make matters more complicated it has to be in a user control so it is possible to add to the controls collection in the forms and remove it to delete it from the screen, and its background is really transparent (no color.transparent) so i can't paint the background to "clear" the previous line. I have it static already (drawn from origin to end) but i can't animate it. I tried to add a timer in the user control but I fail to get a correct algorithm to calculate the intermediate ends of the line while it is growing. Any help would be appreciated. Thanks

  • How to resize pdf graphics produced in R using Illustrator

    - by user1648516
    I am making plots in R using the pdf() command. Graphs look perfect and resize nicely in Acrobat Reader. My usual workflow includes manipulating labels etc. in Illustrator, saving as .eps for submission to publishers or inserting in Word. All works fine for single graphs. Now I am trying to combine 4 graphs into one by manually putting them together in an A4 Illustrator document. However, when I resize the standard 7x7 inches pdf graph in Illustrator to fit in one column of an A4 page (ca 3.4 inches wide), all proportions get screwed up, e.g. lines and symbols outlines become way too thick. Using pdf(..., width=3.4, height=3.4) in R messes up all the symbol and font sizes so carefully chosen to produce the original graph. Why can't I resize the graph within Illustrator the same way I can resize the pdf e.g. in Acrobat Reader?

  • How important is self-teaching in the programming field? [closed]

    - by ThePlan
    I'm 16. I started programming about a year ago when I was about to start high-school. I'm going for a career in programming, and I'm doing my best to learn as much as I can. When I first started, I learned the basics of C++ from a book and I started to learn things by myself from there on. Nowadays I'm much more experienced than I was a year ago. I knew I had to study by myself because high-school won't (likely) teach me anything valuable about programming, and I want to be prepared. The question here is: how important is it to study programming by oneself?

  • R graphics plotting a linegraph with date/time horizontally along x-axis

    - by user2978586
    I want to get a linegraph in R which has Time along x and temperature along y. Originally I had the data in dd/mm/yyyy hh:mm format, with a time point every 30 minutes. https://www.dropbox.com/s/q35y1rfila0va1h/Data_logger_S65a_Ania.csv Since I couldn't find a way of reading this into R, I formatted the data to make it into dd/mm/yyyy and added a column 'time' with 1-48 for all the time points for each day https://www.dropbox.com/s/65ogxzyvuzteqxv/temp.csv This is what I have so far: temp<-read.csv("temp.csv",as.is=T) temp$date<-as.Date(temp$date, format="%d/%m/%Y") #inputting date in correct format plot(temperature ~ date, temp, type="n") #drawing a blank plot with axes, but without data lines(temp$date, temp$temperature,type="o") #type o is a line overlaid on top of points. This stacks the points up vertically, which is not what I want, and stacks all the time points (1-48) for each day all together on the same date. Any advice would be much appreciated on how to get this horizontal, and ordered by time as well as date.

  • When did you feel comfortable with programming?

    - by misterwebz
    I've been programming for about 6 months, but i still feel like i haven't learned anything. Or maybe i'm overwhelmed by the things i still don't know. Am i doing something wrong here or is this normal? I want to be able to work as a freelancer in a year or two, but i'm not sure if that goal is achievable. So when did you feel comfortable using your programming language of choice and how did you learn it?

  • Normalized Device Coordinates to window coordinates

    - by okoman
    I just read some stuff about the theory behind 3d graphics. As I understand it, normalized device coordinates (NDC) are coordinates that describe a point in the interval from -1 to 1 on both the horizontal and vertical axis. On the other hand window coordinates describe a point somewhere between (0,0) and (width,height) of the window. So my formula to convert a point from the NDC coordinate system to the window system would be xwin = width + xndc * 0.5 * width ywin = height + ynfv * 0.5 * height The problem now is that in the OpenGL documentation for glViewport there is an other formula: xwin = ( xndc + 1 ) * width * 0.5 + x ywin = ( yndc + 1 ) * height * 0.5 + y Now I'm wondering what I am getting wrong. Especially I'm wondering what the additional "x" and "y" mean. Hope the question isn't too "not programming related", but I thought somehow it is related to graphics programming.

  • Use the right tool for the job: embedded programming

    - by EmbeddedProg
    I'm interested in programming languages well suited for embedded programming. In particular: Is it possible to program embedded systems in C++? Or is it better to use pure C? Or is C++ OK only if some features of the language (e.g. RTTI, exceptions and templates) are excluded? What about Java in this domain? Thanks.

  • R from java with no graphics: is it worth moving to JRI

    - by LH
    I have a system set up that's been happily running R from a java servlet, spawning processed & hooking into the process's stdin, stdout, and stderr streams, as in the second andwer to this question. After a system upgrade (that included glibc), the input is no longer reaching the R process.* Until now, 'R --vanilla --slave -f [file] ...' was working fine for me. I also have no swing dependencies right now, so I'm somewhat reluctant to add them. (I may actually not be able to add swing dependencies; am I right that using REngine automatically brings swing in? The examples import all of swing.) Are there advantages to switching to JRI? What changes would I need to make to my R script? (It currently reads from stdin and writes to stdout). I'm not finding the provided examples terribly helpful for how to use JRI in this situation. Thanks for your help & comments. *I can't even tell if the problem is data being written too soon or too late, but that's a separate issue/question; if I move to JRI I'm hoping it all becomes moot.

  • Project manager programming background

    - by Henryk Konsek
    Do you think that project manager should have programming background? Do you consider this role as a natural way of evolution for the skilled/leader programmers (as an alternative for architect role)? Or maybe you believe that PM should be just a good manager with a basic understanding of the programming concepts and a fundamental knowledge about the technology you use. What is your experience with working with both kinds of managers (ex-programmers or just managers).
