  • What to do with someone who can only use "the one true language"?

    - by Rob Wells
    G'day, How do you work with someone when they haven't been able to see that there is a range of other languages out there beyond "The One True Path"? I mean someone who hasn't grown up to realise that the modern software professional has a range of tools in his toolbox. Someone who has a well-equipped toolbox and then selects the best tool for the job at hand. The person who's knee jerk reaction is, for example, "We must do this is C++!" "Everything must be done in C++!" What's the best approach for these people? How do you open them up to the fact that "not everything is a nail." cheers,

  • how to send text to a process in a shell script?

    - by Martin
    So I have a Linux program that runs in a while(true) loop, which waits for user input, process it and print result to stdout. I want to write a shell script that open this program, feed it lines from a txt file, one line at a time and save the program output for each line to a file. So I want to know if there is any command for: - open a program - send text to a process - receive output from that program Many thanks.

  • Game network physics collision

    - by Jonas Byström
    How to simulating two client-controlled vehicles colliding (sensibly) in a typical client/server setup for a network game? I did read this eminent blog post on how to do distributed network physics in general (without traditional client prediction), but this question is specifically on how to handle collisions of owned objects. Example Say client A is 20 ms ahead of server, client B 300 ms ahead of server (counting both latency and maximum jitter). This means that when the two vehicles collide, both clients will see the other as 320 ms behind - in the opposite direction of the velocity of the other vehicle. Head-to-head on a Swedish highway means a difference of 16 meters/17.5 yards! What not to try It is virtually impossible to extrapolate the positions, since I also have very complex vehicles with joints and bodies all over, which in turn have linear and angular positions, velocities and accelerations, not to mention states from user input.

  • .NET framework is copied to 'compiler/CLR' and 'GAC?

    - by prosseek
    The book of CLR via C# has this line at page 76. When you install the .NET Framework, tow copies of Microsoft's assembly files are actuall installed. One set is installed into the compiler/CLR directory, and another set is installed into GAC subdirectory I could find the GAC at C:\Windows\Microsoft.NET\assembly, but I couldn't find the compiler/CLR thing. What's the physical directory name of compiler/CLR? I mean, where is it? Why there are two GAC in assembly directory? I find GAC_32 and GAC_MSIL.

  • Why is Objective-C not very popular outside of the Apple community?

    - by Tattat
    I know that the Apple community – including Mac and iPhone developers – mainly use Objective-C for their development language. But it seems that not many people use Objective-C outside of the Apple community, such as in the Windows or Linux worlds. What are the possible reasons that Objective-C is not particularly popular outside of the Apple community?

  • Assign pointers in objective C

    - by Tattat
    -(id)setBigObject:(BigObject *)abc{ self.wl = abc; abc.smallObject = self.smallObject; } I have a abc, which is a big Object, when the user pass the bigObject, abc. I assign to my wl value, so , I write "self.wl = abc;", but I want my smallObject assign to the abc's smallObject, so, I do "abc.smallObject = self.smallObject; " So, when I edit the smallObject in self, it will also changed in the abc's also? Am I right?

  • What are the best websites/web applications for specific languages?

    - by JM4
    Browsing around Stackoverflow, I get overwhelmed with the number of "Why should I learn Python/Ruby/PHP/.Net/jQuery..." and the list goes on. Most answers, although good, are usually battles from language A programmer to language B programmer detailing why one piece sucks more than another. People can discuss the theoretical benefits of one over another but in the end, money/glitz talks and the rest walks. I am more interested in the potential opportunity that can come from one language or another over others. A little background, I am a project manager turned novice 'programmer' out of corporate necessity within the small company I currently work with so I have both relatively no set preference or experience, more out of curiosity. While I realize all are not created equal and for similar things, I think it would be interesting to start a list of the best websites / web applications built on specific languages/frameworks just to highlight the possibilities with each and give somebody like me motivation to say "How the heck was that done? Time to buy a book/take a class and learn." Tell me and I will forget, Show me and I will learn, Involve me and I will understand - Teton Lakota

  • Impressing Potential Employers

    - by superfly123
    Where I am, I can't afford to get certification. I'm definitely not the best programmer, but I do know my junk. I've been writing software in C++ for over 8 years now and have a very good knowledge of the Win32 API. But when applying for jobs, I get rejected every time I send a resume. I've given my resume to recruitment firms and asked them what they think's wrong with it and they said the only thing they could think of is the fact that I don't have certifications to prove that I know my stuff. But in my resume, I explain my previous work and projects, and also note that upon request they can actually see what I've done. Is there anything that you would suggest that might help others to stop ignoring my resumes? Thank you

    - by lego69
    I have this snippet of the code in my header: class A { private: int player; public: A(int initPlayer = 0); A(const A&); A& operator=(const A&); ~A(); void foo() const; friend int operator==(const A& i, const A& member) const; }; implementation of the operator== int operator==(const A& i, const A& member) const{ if(i.player == member.player){ return 1; } return 0; } and I need casting for this part of my code: A *pa1 = new A(a2); assert(i == *pa1); i - is some int, which my function receives I receive an error non-member function, How can I fix it? thanks in advance

  • Having trouble getting GET variables from url.

    - by mchl
    Hey everyone, I'm having trouble with this algorithm to extract the get variables from a url and print them each on a new line like: x=y z=hello etc. but instead it prints a seemingly random section of the url with no newlines to the file. There must be a logic error of some kind but i just can't spot it. for(i_m=0;i_m<len_m;i_m++) { if(var_m[i_m]=='&') { fwrite(var_m+offset_m, 1, amp_m, echo_out); fputc('\n',echo_out); offset_m+=amp_m; amp_m=0; } amp_m++; } any help appreciated.

  • How can I edit a js file sent by the server before it gets to my browser?

    - by pstone
    During a normal browsing session I want to edit a specific javascript file before the browser receives since once it gets there it's impossible to edit. Is there are any tool for this? For what I need it I can't just save it and edit it on my disk. I'm ready to learn how to program it myself but if anyone can point out more or less what I have to do I'd be very grateful. I'd have to intercept the packets until I have the whole file while blocking the browser from receiving it any part of it, then edit it manually and forward it to the same port. I don't think I can do this by just using pcap, I've read a bit about scapy but I'm not sure if it can help me either. Thanks in advance.
