• boolean operations on meshes

  - by lathomas64

  given a set of vertices and triangles for each mesh. Does anyone know of an algorithm, or a place to start looking( I tried google first but haven't found a good place to get started) to perform boolean operations on said meshes and get a set of vertices and triangle for the resulting mesh? Of particular interest are subtraction and union. Example pictures: http://www.rhino3d.com/4/help/Commands/Booleans.htm

• Is it a good practice to code in English? [closed]

  - by Milox

  Possible Duplicate: Do people in non-English-speaking countries code in English? I have a development comming that is intended to be sold across Latin America (Spanish speakers), but I've heard from some partners that is a good practice to always code in English, I mean just code (methods, classes, pages names, etc), labels on GUI are going to be all in Spanish... Code will be edited in the future by developer of companies across Latin America and just maybe some from outside. What do you think?, any experience with this?

• Isn't Java a quite good choice for desktop applications?

  - by tactoth

  At present most applications are still developed with C++, painfully. Lack of portability, in compatible libraries, memory leaks, slow compilation, and poor productivity. Even if you pick only a single from these shortages, it's still a big headache. However the surprising truth is that C++ remains the first choice for desktop applications. Compared to C++ Java has lots of advantages. The success in server side development shows that the language itself is good, Swing is also thought to be as programmer friendly as the highly recognized QT framework (No, never say even a single word about MFC!). All the disadvantages of C++ listed above has a solution in Java. "Performance!", Well that might still be the problem but to my experience it's a slight problem. I'd been using Java to decode some screen video and generate key frames. The video has a duration of more than 1 hour. The time spent on an average machine is just 1 minute. With C++ I don't expect even faster speed. In recent days there are many news on the JIT performance improvements, that make us feel Java is gradually becoming very suitable for desktop development, without people realizing it. Isn't it?

• Are there new flexible texteditors? [closed]

  - by RParadox

  Vi(m) and Emacs are almost 40 years old. Why are they still the standard, and what attempts have been made at coming up with a new flexible editor? Are there any features which can not be built into vim/emacs? My question is similar to this one: Time to drop Emacs and vi? No one had a suggestion, which surprises me. I would have thought that the core of a texteditor is very small and that people brew their own. Perhaps nobody wants to deal with supporting all the modes? Edit to clarify my question: Instead of writing modes and scripts I ask myself, why there is not a much lightweight project, which lets people custom the editor more directly? Vim has 365395 LOC (C lines all included), Emacs 1.5 million LOC. Why is there a project with say 50k LOC, which is the core, why people can use more freely? Perhaps there is such project, I haven't looked very far. I thought about putting together modules from Vim myself and experimenting with some ideas. The core of editing shouldn't be more than 10k? Vim has a lot optimizations which is really an overkill nowadays. Basically I'm looking for a code base for my own editor and Vi/Emacs are I believe not intended to be used in this way. Bill Joy said the following about vi. http://web.cecs.pdx.edu/~kirkenda/joy84.html The fundamental problem with vi is that it doesn't have a mouse and therefore you've got all these commands. In some sense, its backwards from the kind of thing you'd get from a mouse-oriented thing. I think multiple levels of undo would be wonderful, too. But fundamentally, vi is still ed inside. You can't really fool it. Its like one of those pinatas - things that have candy inside but has layer after layer of paper mache on top. It doesn't really have a unified concept. I think if I were going to go back - I wouldn't go back, but start over again.

• Should I use events in this case?

  - by joon

  I'm creating a video player, like a custom YouTube player. All of the GUI elements (progress bar, video player, play button, ...) are different classes, but I obviously need them to communicate. When the progress bar is clicked, or the slider is moved, it needs to send a "seek(x)" command to the video player. Similarly, the video player needs to update the progressbar every frame. Currently I'm doing this by having almost all elements have a link to each other. So when I create the progress bar, I'm telling it where the video player is. But after a while this becomes more and more complicated, and I'm wondering if events would be a better way to do this. Or a main controller class that has all the connections. What should I do?

• What do you feel are characteristics of a mature programmer?

  - by blparker

  Hey all. As part of ongoing research that I am conducting, I would like to ask a crowd, that I feel is the most qualified, to answer a question. What does the community feel are characteristics of a mature programmer? I'm not asking the question because I'm looking to hire or anything of that nature. A colleague and I repeatedly hear a trend throughout universities and specifically computer science departments. The students generally ask questions of the form: How can I become a mature programmer? How can I become a world class programmer? What steps should a new programmer take to become more skilled? So, with that, we are conducting research to attempt to identify an optimized path that would allow an introductory programmer to advance to that of a skilled/mature programmer. Now, I understand that there are many "it depends" out there depending on what vertical industry one works in, but I feel we can determine many common characteristics irrespective of the industry. Any thing you can offer is greatly appreciated. Thanks.

• Writing and Understanding code

  - by Kitex

  I can write code. I can read code but I can't implement good code. How to develop deep understanding of any framework or stuff that we are working on? Is it looking into documentation and working on it? I have seen in this form that people that have great understanding of things they are working on. How is this possible? How to not scrape on the surface only? How to manage time vs learning vs productivity?

• Switching rows and columns in SQL

  When they use SQL Server, one the commoner questions that Ms Access programmers ask is 'Where's the TRANSFORM/PIVOT command? So how do you swap colums and rows in an aggregate table? Do you really need to use a CLR routine for this?

• Useful Custom Business Programs

  - by jacktrades

  Can you name the most useful programs for small business you've seen? This comprises small programs (not big open source projects). I'm referring to tools that have done something different and extremely useful that a normal office suite could not. As a developer, I'm looking to propose more products to small businesses clients. In other words, What 'we developers' can do better than standard tools?

• Handling large integers in python [migrated]

  - by Sushma Palimar

  I had written a program in python to find b such that a prime number p divides b^2-8. The range for b is [1, (p+1)/2]. For small integers it works, say only up to 7 digits. But not for large integers, say for p = 140737471578113. I get the error message for i in range (2,p1,1): MemoryError I wrote the program as #!/usr/bin/python3 p=long(raw_input('enter the prime number:')) p1=long((p+1)/2) for i in range (2,p1,1): s = long((i*i)-8) if (s%p==0): print i

• Long lines of text in source code [closed]

  - by ale

  Possible Duplicate: Is the 80 character limit still relevant in times of widescreen monitors? I used to set a vertical line set at 80 characters in my text editor and then I added carriage returns if the lines got too long. I later increased the value to 135 characters. I started using word wrap and not giving myself a limit but tried to keep lines short if I could because it took a lot of time shortening my lines. People at work use word wrap and don't give themselves a limit.. is this the correct way? What are you meant to do ? Many thanks.

• How to write a real time data acquisition program [closed]

  - by Tosin Awe

  I have to write a program in assembly language that will monitor temperature continuously, and I have no idea where to begin. The temperature must be displayed in BCD format, and the high and low set points will be programmed into the system. if the set points are exceeded then an alarm will be indicated. The low point is 20 degrees Celsius, and the high point is 24 degrees Celsius. Can somebody give me some hints on how to complete this task?

• Rewriting software using Agile methodologies

  - by Asier

  Suppose you have to rewrite an entire application using Agile methodologies, how would you do it? I guess you could write a big bunch of user stories based in the behavior of your current system. And then implement them in small iterations. But this wouldn't mean that we have the requirements UP FRONT?? Also, when would you start releasing? Agile says we should release early and often, but it doesn't make much sense to release before the complete rewrite has been completed. Anybody has used Agile before to rewrite software? How did you do it?

• How do you balance between "do it right" and "do it ASAP" in your daily work?

  - by Flot2011

  I find myself pondering this question times and times again. I want to do things the right way, to write a clean, understandable, correct code that is easy to maintain, but what I really do pretty often is writing a patch upon patch just because there is no time, clients are waiting, a bug should be fixed overnight, the company is losing money on this problem, a manager is pressing hard etc. etc. I know perfectly well that in a long shot I am wasting much more time on these patches, but as this time is spread over months of work, nobody cares. Also, as one of my managers used to say, we don't know if there will be this long shot if we will not fix it now. I am sure I am not the only one entrapped in this endless real/ideal choices. So how you, fellow programmers, are coping with this?

• Attaching Events to Document Better Than Attaching Them to Elements?

  - by Todd

  While bouncing around StackOverflow, I've noticed a number of people attaching events (notably click events) to the document as opposed to the elements themselves. Example: Given this: <button id="myButton">CLICK ME</button> Instead of writing this (using jQuery just for brevity): $('#myButton').on('click', function() { ... }); They do this: $(document).on('click', function() { ... }); And then presumably use event.target to drill down to the element that was actually clicked. Are there any gains/advantages in capturing events at the document level instead of at the element level?

• High-level description of how experimental C++ features are developed?

  - by Praxeolitic

  Herb Sutter in a video answers a question about the concepts proposal considered for C++11 and from his remarks it sounds like multiple groups offered prototype implementations but all of them left concerns about slow compile times. The comment surprised me because it suggests that, at least in some cases, the prototypes being developed are not just proofs of concept -- they're even expected to perform. All the work that must take has me curious. For mature languages, especially C++, how are experimental language features developed? Is it much different from developing a compiler that implements a standard? Does a developer have a sense of if it will work and perform or even if it ever could? What are the most time consuming parts and are any parts surprisingly easier than one might expect? The question is not what does the C++ standards committee do, but rather the part that comes before. When an experimental implementation for a proposal is being put together and there aren't any completely solidified rules, how is the sausage made? I'm not a professional compiler developer nor do I expect answers with step by step accounts. I'd like a high-level idea of how this would be done or if there are any general patterns at all. I don't know what to expect from the answers but even if there are no rules to the process and the small number of people who do this just cowboy it and then, for stuff that worked out, write up the "official version" as a proposal, that answer would still be informative.

• update(100) behaves slightly different than 10 times update(10) - is that a problem? [on hold]

  - by futlib

  While looking into some test failures, I've identified an curious issue with my update logic. This: game.update(100); Behaves slightly different from: for (int i = 0; i < 10; i++) game.update(10); The concrete example here is a rotating entity. It rotates by exactly 360 degrees in the first case, but only by about 352 in the second. This leads to slight variations in how things move, depending on the frame rate. Not enough to be noticeable in practice, but I did notice it when writing tests. Now my question is: Should this be fully deterministic, i.e. the outcome of update(1) * n should equal update(n) exactly? Or is it normal to have some variance and I should make my test assertions more generous?

• What's the most useful piece of logic you use? [closed]

  - by nomaderWhat

  Just tapping away and automatically made use of that one logic algorithm I always use, which you'll probably guess is: (not A) OR (not B) = not (A AND B) Curious if this is the case for just about everyone else, and more curious if there is a different algorithm that other programmers make use of that is just as if not more useful to them. Really hoping for the latter, cause the one above is well... so boring.

• How should I define my Java Objects?

  - by HonorGod

  I have a data grid where I sort of show the following information - All Guests Total Adults = 22 Total Children = 27 Confirmed Total Adults = 9 Total Children = 13 Country = Germany Total Adults = 5 Total Childres = 6 Friends Adults = 2 Children = 2 Relatives Adults = 3 Children = 4 Country = USA Total Adults = 4 Total Childres = 7 Friends Adults = 2 Children = 5 Relatives Adults = 2 Children = 2 Tentative Total Adults = 13 Total Children - 14 Country = Australia Total Adults = 7 Total Childres = 8 Friends Adults = 2 Children = 3 Relatives Adults = 5 Children = 5 Country = China Total Adults = 6 Total Childres = 6 Friends Adults = 2 Children = 4 Relatives Adults = 4 Children = 2 And in the database what I have is data at the lowest level which is Friends / Relatives and the corresponding countries set as a look-up value which in indirectly connected to another look-up that can tell me if they fall under confirmed or tentative. I guess my question is how do I layout my Java Object and perform the aggregations and give it back to the client. I am not sure if I am clear with my question, but feel free to comment so I can update the question accordingly.

• Working for a company vs starting my own? [closed]

  - by Mark

  I need some advice, I am considering going to grad school for CS. I have a few big projects I came up with on my own that I am extremely motivated to work on and complete and try to turn it into a career. I am currently completing an internship working for a big company, decent pay, 9-5 hours in an office. I feel like working for the same company many people would enjoy and like, is extremely boring in my opinion and procedural at times and kills my motivation. As a result, I am kind of unsure if I should continue to get my CS M.S. degree and start working for a big company? What I would enjoy doing most is working for myself and developing my own project, but I am not sure if I will be able to finanically support myself doing that and I do not want to miss out on a big opportuinities/ job offers to work for a company. With that being said, I will never know if my project will ever succeed if I don't give it %110 of my time and dedication, so if I decide to go that route and work on my own project, I will have to set everything else aside, If anyone could give me any advice on what they think about my situation?

• Map multiple functions over a single data item

  - by Linus Norton

  I'm in the process of learning Scala and I came across a scenario today where I need to map multiple functions over a single piece of data and wondered if there was a formal name for this. It sort of feels like the inverse of map. I'm not sure this is the correct way of expressing it, but this is what I did: dmap(x: Object, fns: List[Function]) = fns.map(_(x)) Is there a built in way to do something similar? Is there a formal name for this function?

• Changing a Sprite When Hit in GameMaker

  - by Pixels_

  I am making a simple little Galaga style game. I want the objects sprite to change whenever it is hit. For example if a laser hits an alien then the sprite takes 1 out of 4 damage to its health points (HP). However I want the sprite to change from green to yellow after 1 hit, yellow to orange after 2 hits, orange to red after 3 hits, and red to pixel explosion after all 4 HPs are lost. That way you can easily distinguish the amount of health each alien has left. How can I do this? Preferably explain it in code.

• Should sanity be a property of a programmer or a program?

  - by toplel32

  I design and implement languages, that can range from object notations to markup languages. In many cases I have considered restrictions in favor of sanity (common knowledge), like in the case of control characters in identifiers. There are two consequences to consider before doing this: It takes extra computation It narrows liberty I'm interested to learn how developers think of decisions like this. As you may know Microsoft C# is very open on the contrary. If you really want to prefix your integer as Long with 'l' instead of 'L' and so risk other developers of confusing '1' and 'l', no problem. If you want to name your variables in non-latin script so they will contrast with C#'s latin keywords, no problem. Or if you want to distribute a string over multiple lines and so break a series of indentation, no problem. It is cheap to ensure consistency with restrictions and this makes it tempting to implement. But in the case of disallowing non-latin characters (concerning the second example), it means a discredit to Unicode, because one would not take full advantage of its capacity.

• How can I add a custom item to the Sound Indicator?

  - by con-f-use

  One of the strength of Unity are the various standardized indicators. I want to customize the sound indicator with an additional menu entry that runs a small shell script. I'm not afraid of a little Python code and I hope someone can point me to the right subroutine in the right file. I suspect that will be fairly easy but all the indicators are just so bloated that I can't look through their code in a reasonable time. Any help is appreciated. I know it is possible as the marvelous Skype-Wrapper does it.
