  • How to point to jdni.properties file to set properties in Java

    - by prosseek
    I can use System.getProperties() method to set properties in Java. System.getProperties().put("java.naming.factory.initial", "fr.dyade.aaa.jndi2.client.NamingContextFactory"); System.getProperties().put("java.naming.factory.host", "localhost"); System.getProperties().put("java.naming.factory.port", "16400"); How can I get the same effect by reading the properties stored in a file? When I have a jdni.properties with the following content: java.naming.factory.initial fr.dyade.aaa.jndi2.client.NamingContextFactory java.naming.factory.host localhost java.naming.factory.port 16400 How can I teach Java to read them as properties?

  • How to call IronPython function from C#/F#?

    - by prosseek
    This is kind of follow up questions of http://stackoverflow.com/questions/2969194/integration-of-c-f-ironpython-and-ironruby In order to use C/C++ function from Python, SWIG is the easiest solution. The reverse way is also possible with Python C API, for example, if we have a python function as follows def add(x,y): return (x + 10*y) We can come up with the wrapper in C to use this python as follows. double Add(double a, double b) { PyObject *X, *Y, *pValue, *pArgs; double res; pArgs = PyTuple_New(2); X = Py_BuildValue("d", a); Y = Py_BuildValue("d", b); PyTuple_SetItem(pArgs, 0, X); PyTuple_SetItem(pArgs, 1, Y); pValue = PyEval_CallObject(pFunc, pArgs); res = PyFloat_AsDouble(pValue); Py_DECREF(X); Py_DECREF(Y); Py_DECREF(pArgs); return res; } How about the IronPython/C# or even F#? How to call the C#/F# function from IronPython? Or, is there any SWIG equivalent tool in IronPython/C#? How to call the IronPython function from C#/F#? I guess I could use "engine.CreateScriptSourceFromString" or similar, but I need to find a way to call IronPython function look like a C#/F# function.

  • Making Visual C++ DLL from C++ class

    - by prosseek
    I have the following C++ code to make dll (Visual Studio 2010). class Shape { public: Shape() { nshapes++; } virtual ~Shape() { nshapes--; }; double x, y; void move(double dx, double dy); virtual double area(void) = 0; virtual double perimeter(void) = 0; static int nshapes; }; class __declspec(dllexport) Circle : public Shape { private: double radius; public: Circle(double r) : radius(r) { }; virtual double area(void); virtual double perimeter(void); }; class __declspec(dllexport) Square : public Shape { private: double width; public: Square(double w) : width(w) { }; virtual double area(void); virtual double perimeter(void); }; I have the __declspec, class __declspec(dllexport) Circle I could build a dll with the following command CL.exe /c example.cxx link.exe /OUT:"example.dll" /DLL example.obj When I tried to use the library, Square* square; square->area() I got the error messages.

  • representing graph using database

    - by prosseek
    I need to represent graph information with database. Let's say, a is connected to b, c, and d. a -- b |_ c |_ d I can have a node table for a, b, c, and d, and I can also have a link table (FROM, TO) - (a,b), (a,c), (a,d). For other implementation there might be a way to store the link info as (a,b,c,d), but the number of elements in the table is variable. Q1 : Is there a way to represent variable elements in a table? Q2 : Is there any general way to represent the graph structure using database?

  • Article about code density as a measure of programming language power

    - by prosseek
    I remember reading an article saying something like "The number of bugs introduced doesn't vary much with different programming languages, but it depends pretty much on SLOC (source lines of code). So, using the programming language that can implement the same functions with smaller SLOC is preferable in terms of stability." The author wanted to stress the advantages of using Functional Programming, as normally one can program with a smaller number of LOC. I remember the author cited a research paper about the irrelevance of choice of programming language and the number of bugs. Is there anyone who knows the research paper or the article?

  • Install Python 2.6 without using installer on Win32

    - by prosseek
    I need to run a python script on a machine that doesn't have python installed. What I did was as follows. Copy python.exe, python26.dll, msvcr90.dll and Microsoft.VC90.CRT.manifest zip all the directory in LIBs directory as the python26.zip copy all the necessary dll/pyd file inside the DLL directory. It seems to work, but when I change the python26.zip to the other name such as pythonlib.zip. It cannot find the python library anymore. Q1 : What's the magic behind the python26.zip name? The python automatically finds a library inside a python26.zip but not with different name? Q2 : If I have python26.zip at the same directory where python.exe/python26.dll is, I don't need to add path sys.path.append(THE PATH TO python26.zip). Is it correct?

The HTML generated html has the jQuery, and according to this site, it's just one line of code to have a zebra table, but I'm not sure how to use jQuery to make a zebra table. $("tr:nth-child(odd)").addClass("odd"); Q: How to use jQuery with Sphinx? Q: Is there any other way to have a zebra table with Sphinx?

  • Does Ruby have a special stack for returning a value?

    - by prosseek
    The following Ruby code def a(b,c) b+c end is the same as follows with Python def a(b,c): return b+c It looks like that ruby has the special stack that stores the final evaluation result and returns the value when a function is called. If so, what's the name of the stack, and how can I get that stack? If not, how does the Ruby code work without returning something?

  • Running python/ruby script on iPhone?

    - by prosseek
    From the recent news from the Apple, I learned that one has to use C/C++/Objective-C for iPhone App. Accordingly, it's not possible to use MacPython or similar to make iPhone App. But as the python/ruby interpreter itself is written in C, isn't it OK to make python/ruby interpreter for iPhone to run the scripts on iphone? Is this possible? Does Apple support this? Or does someone implemented this? Or, the user should hack to do this?

  • Running python batch file that has a path with SPACE character

    The batch file is something like this, I put the python in some directory that has SPACE character in its path. C:\"Documents and Settings"\Administrator\Desktop\bracket\python\python C:\\"Documents and Settings"\\Administrator\\Desktop\\bracket\\[10,20]\\brackettest.py When I run this one, I get this error.

Wrapping the path doesn't solve this problem. "C:\\Documents and Settings\\Administrator\\Desktop\\bracket\\[10,20]\\brackettest.py" Are the brackets ('[]') cause of the problem? On Mac, python works well with bracket character.

  • Trimming byte array when converting byte array to string in Java/Scala

    - by prosseek
    Using ByteBuffer, I can convert a string into byte array: val x = ByteBuffer.allocate(10).put("Hello".getBytes()).array() > Array[Byte] = Array(104, 101, 108, 108, 111, 0, 0, 0, 0, 0) When converting the byte array into string, I can use new String(x). However, the string becomes hello?????, and I need to trim down the byte array before converting it into string. How can I do that? I use this code to trim down the zeros, but I wonder if there is simpler way. def byteArrayToString(x: Array[Byte]) = { val loc = x.indexOf(0) if (-1 == loc) new String(x) else if (0 == loc) "" else new String(x.slice(0,loc)) }

    I installed emacs 23.3.1 in c:/emacs-23.3. Following the hints in this page, I updated the site-start.el to set HOME environment variable. (setenv "HOME" "c:/users/USER/emacs") And I made c:/users/USER/.emacs (like I did in unix/mac) to write the code for using slime, but it doesn't seem to start slime correctly. Is this a correct way of setting emacs in Windows 7? Where do I put the .emacs file?
