• How to start to gain experience of managing a project

  - by Tim

  There are some job requirements of project management experience for a programmer, such as: the candidate has to have some experience managing a project, not necessarily with subordinates, but rather having worked on a project all the way from design down to test. I was wondering what "subordinates" mean here? if there are some books, webpages or elsewhere with both general guideline and simple practical sample projects to help one get some basics about the whole process of a project. I am particularly interested in projects for both Linux and Windows, in C, C++, Python, Java. I am considering to start by playing on my own, not eager to find a company yet. My major was not CS, so I might lack the basics.

• Is C++ indispensible for AAA game engines, as long as we have console-platform games? [closed]

  - by user1174924

  C++ has remained the industry standard for game engines much because of its features.. The primary reasons are(afaik): Technical reasons - High performance, native runtime, portibility, negligible latency, and more recently concurrency. Socio-Technical reasons - Availability of Libraries, Legecy stuff, most scripting languages on games have a good C api (ex lua), Good IDEs and most recently improved Development time.(C++11) Social reasons - People know C++, Licenced technologies, and battle proven. Does this make C++ for game engines indispensible, so long we have game consoles? Would not, the above features make me implement new graphics technology in C++ only? Edit: Will learning C++ garuntee me a job as a game engine dev In the future? I want to master every aspect of the language, but I already know C# and python. Should I allocate my time learning C++. I want to be a game engine developer.

• A good language for c# dev to expand his mind [closed]

  - by Jan Kratochvil

  I have some free time on my hands and I was thinking about learning a new language. I do not plan to use it in my day-to-day job, but I rather want to expand my way of thinking to get a better sense where the dev world is heading from a language perspective and to don't get stuck in my way when programming by rather try new approaches. I was thinking either a functional language, like Haskell or F# (which is a bit more 'pragmatic from a .NET dev standpoint) or something dynamic (like Python, that in my oppinion has nicer syntax than Ruby). What can you recommend that is enjoyable, at least a bit practical, but most of all, new (from a c# dev perspective). I appreciate any answers.

• Can I rightfully claim this as my own project if I recieved help online?

  - by Brad Guy

  Basically I'm new to network programming in Python, so I went on a tutorial online to find out about it. Using what was taught in the tutorial (creating a socket, connecting to ports, etc), I modified the code so that I made a program where two computers can send messages to one another. If I were to apply for a job and show this to my interviewers, would the code for it technically be mine? It is fair to say that I didn't modify the code by that much; However, what if for example I modified it into something like a tic-tac-toe game, where two users play each other from different PCs, would the code then be mine? I just don't want to look like a plagiarizer hence why I ask.

• C# on ubuntu 12.04

  - by Deus Deceit

  Is C# a good choice for ubuntu programming? E.g unity, or applications that will run on ubuntu? Am I doing good wanting to learn C# when I'm determined to stick with ubuntu and develop on it or for it? If not, can you give me reasons why? And which languages would be better than c# for ubuntu development? I already know c, c++, java(basics), php, mysql, python(basics). I like to learn new stuff, but stuff that worth my time. Does C# worth my time? If c# worth my time, here's what I have done and what I need: I installed all mono packages I could find on the ubuntu standard repositories. Now I want a good tutorial to get me started. I'm a complete noob with c# so a basic tutorial and how to compile run under ubuntu 12.04 would be great.

• Need an engine for MMO mockup

  - by Kayle

  What I don't need is an MMORPG engine, at the moment. What I do need is a flexible easy-to-use engine that I can make a mock-up with. I don't need support for more than 10 players in an instance, so any multiplayer platform is probably fine. I need an engine with which I can create the following core features: Waves of simple AI enemies that have specific objectives (move to point A, destroy target, move to point B). The units present can be between 50-200 in number. An over-the-shoulder view and the ability to control a team of 3 (like Mass Effect or the latest Dragon Age) Functioning inventory system Right now, all I can really think of is Unreal or Source. Any other suggestions? Again, this is a proving mock-up, not an actual MMO. I'm not terribly worried about the visual aspects as we just want to test mechanics. Note: Can write some scripts in Python, Ruby, or Lua, if necessary.

• Most Useful New Technology?

  - by Craig Ferguson

  I'm looking to take a sort of sabbatical, and I'd love to use it to learn a new technology. My question is this: What's the most useful "new" technology for a software engineer to use? Node.js, iOS programming, Android, something else? I'd prefer to stay away from anything too new or experimental, since those are, in my experience, rarely actually used in professional production environments (for better or worse). Does anyone happen to have stats on how many jobs there are for each new technology or have anecdotes about how fun each one is? I've been using python/Django, so that's out, and it's similar to Ruby so i don't think learning Ruby would be that useful to expanding my skills. Anyone have any other ideas?

• DOMDocument programming: a lot of little dilemmas, how to solve them?

  - by Peter Krauss

  I need elegance and performance: how to decide by the "best implementation" for each DOM algorithm that I face. This simple "DOMNodeList grouper" illustrate many little dilemmas: use iterator_to_array or "populate an array", when not all items need to be copied. use clone operator, cloneNode method or import method? use parentNode::method() or documentElement::method? (see here) first removeChild or first replaceChild, no avoids "side effects"? ... My position, today, is only "do an arbitrary choice and follow it in all implementations" (like a "Convention over configuration" principle)... But, there are another considerations? About performance, there are some article showing benchmarks? PS: this is a generic DOM question, any language (PHP, Javascript, Python, etc.) have the problem.

• Is there a language offering LISP-like macros with a more complex syntax?

  - by blubb

  LISP's macros are extremely powerful constructs, and the inability to introspect and modify the program itself beyond the method signature level has always struck me as a limitation. Yet I favour "complex" syntax because it tends to be closer to natural language. So far I have failed to find a language which combines a powerful macro mechanism such as LISP's with a naturally looking syntax (1). Is anyone aware of such a language? Footnote: I would consider python to have a naturally looking syntax as it allows constructs like this: if 0 < a < 5 and b in list. The avoidance of braces to structure blocks is irrelevant in this case, though.

• Assemble static site from templates? (don't want to reinvent the wheel)

  - by raindog308

  I have a site that is 100% static content (no php, just some javascript). There's several "blocks" like the header, menu, footer, etc. that are the same on each page. Rather than do a lot of copy/pasting, I was thinking of some kind of template system where I could run a CLI command (in php, perl, python, shell, whatever) and have it replace all the block tags with the actual block text. I did see some answers in this question, but those seem oriented towards "we provide the style and layout, you provide the text". In my case, I have everything as far as layout, css, etc. - just want to do a glorified sed. Before I invent the wheel, I was wondering if there was a tool out there already.

• Language-independent sources on 2D collision detection [on hold]

  - by Phazyck

  While making a Pong clone with a friend, we had to implement some 2D collision detection. For research purposes, my friend dug up a book called "AdvancED Game Design with Flash" by Rex Van Der Spuy. This book was clearly targeted at implementing 2D collision detection in ActionScript, and I also have some problems with how the concepts are presented, e.g. presenting one method as better than another, without explaining that decision. Can anyone recommend some good material on 2D collision detection? I'd prefer it if it kept the implementation details as language-independent as possible, e.g. by implementing the concepts in pseudo-code. Language-specific materials are not completely unwelcome though, though I'd prefer those to be in either Java, C#, F# or Python or similar languages, as those are the ones I'm most familiar with. :-) Lastly, is there perhaps widely known and used book on collision detection that most people should know about, like a 'the book on 2D collision detection'?

• Ready to Open source the software, but want to make some money out of it.

  - by byteofprash

  I'm an UG Student and an Entrepreneur. I have started a small company with which I'm trying to provide solutions, to various companies in my city, through my software. I put in 30-40 hours of coding and development. I've been a huge fan of Open Source projects and I've also built by software on python. But now when it comes to selling my software to my customers, I expect money. (Am I being a Hypocrite?) Is there any OSS license under which I can make money and also make my source open? Please suggest. Or any other way to make money with my softwares? (I guess I deserve some credit. If not the code, atleast the ideas? :D )

• What does it mean to "have experience with the Unix/Linux command line"? [closed]

  - by Aerovistae

  I'm a new comp sci grad applying to jobs, and this requirement confuses me, especially since the job description (Python back-end developer) says it's the single most important thing ("Everything else we can teach you!") I mean, I know how to use the command line... I know your standard run-of-the-mill stuff like navigating around and manipulating files and permissions and using pipes and running applications, but what are they looking for when they say something like that? I'm aware there's no end to what you can do with the command line, but I was under the impression that after a certain point it's the sort of thing that only benefits server/system administrators.

• DRY, string, and unit testing

  - by Rodrigue

  I have a recurring question when writing unit tests for code that involves constant string values. Let's take an example of a method/function that does some processing and returns a string containing a pre-defined constant. In python, that would be something like: STRING_TEMPLATE = "/some/constant/string/with/%s/that/needs/interpolation/" def process(some_param): # We do some meaningful work that gives us a value result = _some_meaningful_action() return STRING_TEMPLATE % result If I want to unit test process, one of my tests will check the return value. This is where I wonder what the best solution is. In my unit test, I can: apply DRY and use the already defined constant repeat myself and rewrite the entire string def test_foo_should_return_correct_url(): string_result = process() # Applying DRY and using the already defined constant assert STRING_TEMPLATE % "1234" == string_result # Repeating myself, repeating myself assert "/some/constant/string/with/1234/that/needs/interpolation/" == url The advantage I see in the former is that my test will break if I put the wrong string value in my constant. The inconvenient is that I may be rewriting the same string over and over again across different unit tests.

• Why is Prolog associated with Natural Language Processing?

  - by kyphos

  I have recently started learning about NLP with python, and NLP seems to be based mostly on statistics/machine-learning. What does a logic programming language bring to the table with respect to NLP? Is the declarative nature of prolog used to define grammars? Is it used to define associations between words? That is, somehow mine logical relationships between words (this I imagine would be pretty hard to do)? Any examples of what prolog uniquely brings to NLP would be highly appreciated.

• How would you approach developers you don't already know as a developer to offer them a position? [closed]

  - by Kit Sunde

  We've been trying to find a second developer for the company and have posted job ads online but so far there have been no developers that have been interested, and only a single one that has some experience in Python (that failed a fairly basic practical). It seems like the it's really difficult to find decent people here in Singapore, even reasonable juniors that you can teach. I'm contemplating whether I should go reach out directly to people on Stack Overflow and github and in the hopes that they are interested. I'm thinking I would message the person with only a few sentences, stating the they seems capable from their online presence and that I'd like to work with them. Is this kosher? I know I dislike recruiters and unsolicited mail just as much as the next guy.

• what's the overhead when allocating objects/arrays in Java?

  - by Gnijuohz

  How many bytes an array occupies in Java? Assume It's a 64bit machine and also assume there are N elements in an array, so all these elements would take up 2*N, 4*N or 8*N bytes for different types of array. And a lecture in Coursera says that it would occupy 2*N+24, 4*N+24 or 8*N+24 bytes for a N element array and the 24 byte is called overhead, but didn't explain it. Also objects have overheads, which is 16 bytes. What exactly are these overheads? Also, do these overheads only exist in Java? How about C, C++ and Python?

• Is it viable to become a contract programmer straight out of college?

  - by M G

  I have a Bachelor of Science in Computer Science and four months research experience designing and implementing a research project. I realize this is highly dependent on my skill set - which includes C, C++, Java, Python, and SQL. I feel I have an advantage in two ways: I am young and am not afraid to work overtime. I am willing to take lower pay to gather a client base/experience, and work nights/weekends to get a few projects under my belt. This may be cliche, but I feel that I can learn new technologies quicker than most. At the very least, I am not a slow study. With this being said, is it viable for me to become a contract programmer? Or do I need the 10+ year skill set that most contractors bring to the table?

• Is C++ really a bad language for beginners? [duplicate]

  - by Chris

  This question already has an answer here: Is C++ suitable as a first language? 24 answers I'm learning C++ right now, and it's the first language I'm learning. I keep seeing on stackexchange and other forums (Reddit, etc.) that I should drop C++ and learn a higher level language like Python or Java. The only arguments I see are that "C++ is harder to learn and is more low-level than others." which don't really give a reason NOT to learn it. I want to know if there are any actual reasons for dropping C++ and taking up another, "easier" language. Or if I should keep focusing on it, and just learn others later (which is what I plan on doing).

• How do operating systems… run… without having an OS to run in?

  - by Plazmotech Binary

  I'm really curious right now. I'm a Python programmer, and this question just boggled me: You write an OS. How do you run it? It has to be run somehow, and that way is within another OS? How can an application run without being in an OS? How do you tell the computer to run, say, C, and execute these commands to the screen, if it doesn't have an OS to run in? Does it have to do with a UNIX kernel? If so, what is a Unix kernel, or a kernel in general? I'm sure OSes are more complicated than that, but how does it work?

• how to install gerix on ubuntu 12.04 using backtrack repositories?

  - by werever

  I got instructions from here, and I found several sites with similar instructions but somethig is wrong with the repositories on 12.04. This should work for 11.10 and previous versions. Any ideas how to install backtrack repos and some back track apps on 12.04? I read about downloading the .deb package for gerix and manually making the same folder structure that gerix uses on backtrack, then manually run the python script, but this way didn't work for me either. How can I get gerix installed and working on my Ubuntu 12.04 system?

• Deleted files not increasing available free space on Ubuntu (as reported by df -h)

  - by Homunculus Reticulli

  I am writing data munging scripts (python and bash), to munge data and import large quantities of text files into a database. I am currently in the test phase, so I am generating several K's of files and deleting them (the files consume about 20G of space). After a test run, I delete the files (sometimes without having imported into the database). I notice that there is a steady decrease in the amount of free space on my disk (as reported by df -h). I don't understand this, as I use rm * (in the data directory), and in the cases where I use Nautilus, I empty the Trash bin as well. Similarly, I notice that when I import the data into the (postgresql) database, and then delete the data from the tables using DELETE FROM tablename;, the size consumed in the postgresql data directory does not go down either. Currently, I have lost approximately 200G from hard drive, and I need to reclaim that - but don't know what to do to reclaim it - any ideas?. I am running Ubuntu 10.0.4 LTS + postgresql 8.4

• A question on choosing the next programming language between C/C++ and other languages

  - by SidCool

  I am a java developer (web app and standalone applications) who knows JavaScript, HTML, CSS and has mostly worked on Web applications. I have no knowledge of C/C++ or any other lower level languages. I feel like I should strengthen my CS basics by learning a fundamental language. Should it be C or C++? I am also inclined to learn Objective-C. Does it need basics of C or C++? Or should I go for new languages like Python, Google's Go etc. I know this is a cliche question asked very frequently, but I can use some help here.

• Is it normal to feel bad when someone insults a programming language? [closed]

  - by iammilind

  Few examples before the question: "A language is just a tool; Better to worry only about the concept." "C++ is just an object oriented language." "Java is more about the libraries and less about programming." "C# is just a Microsoft's version of Java with some extra things from C++." "Python is a scripting language used mainly for testing purpose." ... All these statements are made knowingly or unknowingly from my colleagues/friends and I often get to hear them. I feel bad when someone brings down any programming language. I don't know how to respond. Is there any one liner to enlighten those people?
