  • Tests that are 2-3 times bigger than the testable code

    - by HeavyWave
    Is it normal to have tests that are way bigger than the actual code being tested? For every line of code I am testing I usually have 2-3 lines in the unit test. Which ultimately leads to tons of time being spent just typing the tests in (mock, mock and mock more). Where are the time savings? Do you ever avoid tests for code that is along the lines of being trivial? Most of my methods are less than 10 lines long and testing each one of them takes a lot of time, to the point where, as you see, I start questioning writing most of the tests in the first place. I am not advocating not unit testing, I like it. Just want to see what factors people consider before writing tests. They come at a cost (in terms of time, hence money), so this cost must be evaluated somehow. How do you estimate the savings created by your unit tests, if ever?

  • Ternary operator or chosing from two arrays with the boolean as index

    - by ajax333221
    Which of these lines is more understandable, faster jsPerf, easier to maintain?: arr = bol ? [[-2,1],[-1,2]] : [[-1,0],[-1,1]]; //or arr = [[[-1,0],[-1,1]], [[-2,1],[-1,2]]][bol*1]; I usually write code for computers (not for humans), but this is starting to be a problem when I am not the only one maintaining the code and work for a team. I am unsure, the first example looks neat but are two different arrays, and the second is a single array and seem to transmit what is being done easier. I also considered using an if-else, but I don't like the idea of writing two arr = .... Or are there better options? I need serious guidance, I have never worried about others seeing my code.

  • .licx need to be added to the main project?

    - by SeaBiscuit
    Hello, I have the following situation. I have a main project that's calling some other dll made by me (MainProject). One of the dll are using a third party dll that is licenced (DllA is using DllB - licenced). In the DllA project I've attached the file licences.licx as embedded resource. Why can't I use the DllA from the main project? The licences.licx must be added to the main solution project? To the project that's generating the exe file?? Thank you,

  • NetBeans/C++ - how to choose the "main file" other than when creating a project?

    - by Petike
    Hello, when I am creating a C++ project in NetBeans, there is a toggle button "Create main file" - I just enter a name for it and that's all. The problem is that I cannot put that file in a "different" folder than right in the main project folder. And I am "used" to put all the source files in a "src" folder (and its subfolders), but at the "project creation time" I "cannot" put the main file there. So I tried "not" to create the main file at project creation, but after that create manually the "src" file and then create a "cpp" file in that folder (this is "allowed" in NetBeans). But NetBeans could not find "which" is the main file. So how can I choose the main file other than when creating a project (if it is possible)?

  • Change Text on Landscape mode with Java Code and not XML (Android)

    - by Chowza
    I wrote my layout entirely in java code because it was just more convenient. (I had a lot of textViews and using for statements were more convenient). However, my TextViews require the day of the week and in portrait mode, I would like to cut the day of the week to a short form. For example, I want "Sunday" to show "Sun" for portrait mode, but "Sunday" for landscape mode. I understand how to do this in XML files, but how do I do it in code? I.e. sample code: LinearLayout parent = new LinearLayout(getApplicationContext()); parent.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT)); TextView example = new TextView; example.setLayoutParams(mparams); example.setText("Sunday"); //<--make this "Sun" when in portrait but "Sunday" in landscape parent.addView(example);

  • Visual Website Optimizer and Code Igniter

    - by absentx
    We are trying to integrate visual website optimizer into a site of ours that uses Code Igniter. The problem is when we go into the VWO control panel to look at stats and previews nothing seems to be working. In the previews panel, all of them come up as code igniter error pages that say "The URI you submitted has disallowed characters." I have researched some solutions to this and have tried changing the regex in system/config to allow more characters, all characters etc and I am still having the problem. Any known issues or problems trying to integrate VWO and Code Igniter? This definitely seems to be a url issue but I can't nail it down.

  • delphi finalizalization code in a DLL

    - by PA
    I am moving some functions to a shared DLL (I want to have some called as a Windows hook). The actual functions are currently in a unit, and it happens to have some initialization and some finalization code. I was initially thinking on doing a direct transformation from a unit to a library. So I moved the initialization code in between the main begin and end.. But then I realized I had no place to move the finalization code. I should create and register an special DLL entry point, instead. My question is. Can I leave the unit with all the functions and the initialization and finalization codes and just create a library stub that uses the unit? will the finalizationit be called?

  • Why is this js code so slow?

    - by SpiderPig
    This code takes 3 seconds on Chrome and 6s on Firefox. If I write the code in Java and run it under Java 7.0 it takes only 10ms. Chrome's JS engine is usually very fast. Why is it so slow here? btw. this code is just for testing. I know it's not very practical way to write a fibonacci function fib = function(n) { if (n < 2) { return n; } else { return fib(n - 1) + fib(n - 2); } }; console.log(fib(32));

  • How can I write my code to attempt a database action but continue executing code on failure?

    - by Chris
    Simple question I guess, I want to use PHP to write an update to an existing row in my database, if it doesn't happen I want to log the failure but continue executing the code. While it would be nice to have records of failures to track down issues, that the update failed isn't that important to my user, nor will it affect the running of any other code; the query is simply for a 'cosmetic' but entirely unnecessary piece of information. My database class's query function is set to die on failure, could I modify that or is there another way of doing it without altering my standard query code?

  • How do you make a character jump, both on objects and just normal jump?

    - by haxerflaxer
    Hi, I'm kind of a beginner when it comes to java programming, and I have a project in school where I'm going to create a game much like Icy Tower. And my question is, how am I going to write to make the character stand on the ground and be able to jump up on objects? Here's my code so far: Part one package Sprites; import java.awt.Image; import java.awt.event.KeyEvent; import javax.swing.ImageIcon; public class jumper { private String jump = "oka.png"; private int dx; private int dy; private int x; private int y; private Image image; public jumper() { ImageIcon ii = new ImageIcon(this.getClass().getResource(jump)); image = ii.getImage(); x = 50; y = 100; } public void move() { x += dx; y += dy; } public int getX() { return x; } public int getY() { return y; } public Image getImage() { return image; } public void keyPressed(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_LEFT) { dx = -5; ImageIcon ii = new ImageIcon(this.getClass().getResource("oki.png")); image = ii.getImage(); } if (key == KeyEvent.VK_RIGHT){ dx = 5; ImageIcon ii = new ImageIcon(this.getClass().getResource("oka.png")); image = ii.getImage(); } if (key == KeyEvent.VK_SPACE) { dy = -5; } if (key == KeyEvent.VK_DOWN) { dy = 5; } } public void keyReleased(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_LEFT) { dx = 0; } if (key == KeyEvent.VK_RIGHT){ dx = 0; } if (key == KeyEvent.VK_SPACE) { dy = 0; } if (key == KeyEvent.VK_DOWN) { dy = 0; } } } Part two package Sprites; import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.Toolkit; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.KeyAdapter; import java.awt.event.KeyEvent; import javax.swing.JPanel; import javax.swing.Timer; public class board extends JPanel implements ActionListener { private Timer klocka; private jumper jumper; public board() { addKeyListener(new TAdapter()); setFocusable(true); setBackground(Color.WHITE); setDoubleBuffered(true); jumper = new jumper(); klocka = new Timer(5, this); klocka.start(); } public void paint(Graphics g) { super.paint(g); Graphics2D g2d = (Graphics2D)g; g2d.drawImage(jumper.getImage(), jumper.getX(), jumper.getY(), this); Toolkit.getDefaultToolkit().sync(); g.dispose(); } public void actionPerformed(ActionEvent e) { jumper.move(); repaint(); } private class TAdapter extends KeyAdapter { public void keyReleased(KeyEvent e) { jumper.keyReleased(e); } public void keyPressed(KeyEvent e) { jumper.keyPressed(e); } } } Part three package Sprites; import javax.swing.JFrame; public class RType extends JFrame { public RType() { add(new board()); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(800, 600); setLocationRelativeTo(null); setTitle("R - type"); setResizable(false); setVisible(true); } public static void main(String[] args) { new RType(); } } I really appreciate all the help I can get!

  • Nginx + PHP-FPM executes script, but returns 404

    - by MorfiusX
    I am using Nginx + PHP-FPM to run a Wordpress based site. I have a URL that should return dynamically generated JSON data for use with the DataTables jQuery plugin. The data is returned properly, but with a return code of 404. I think this is a Nginx config issue, but I haven't been able to figure out why. The script 'getTable.php' works properly on the production version of the site which is currently using Apache. Anyone know how I can get this to work on Nginx?

    Was: Design by contract: predict methods needed, discipline yourself and deal with code that comes to mind I like the idea of designing by contract a lot (at least, as far as I understand the principal). I believe it means you define intefaces first before you start implementing actual code, right? However, from my limited experience (3 OOP years now) I usually can't resist the urge to start coding pretty early, for several reasons: because my limited experience has shown me I am unable to predict what methods I will be needing in the interface, so I might as well start coding right away. or because I am simply too impatient to write out the whole interfaces first. or when I do try it, I still wind up implementing bits of code already, because I fear I might forget this or that imporant bit of code, that springs to mind when I am designing the interfaces. As you see, especially with the last two points, this leads to a very disorderly way of doing things. Tasks get mixed up. I should draw a clear line between designing interfaces and actual coding. If you, unlike me, are a good/disciplined planner, as intended above, how do you: ...know the majority of methods you will be needing up front so well? Especially if it's components that implement stuff you are not familiar with yet. ...resist the urge to start coding right away? ...deal with code that comes to mind when you are designing the interfaces? UPDATE: Thank you for the answers so far. Valuable insights! And... I stand corrected; it seems I misinterpreted the idea of Design By Contract. For clarity, what I actually meant was: "coming up with interface methods before implementing the actual components". An additional thing that came up in my mind is related to point 1): b) How do you know the majority of components you will be needing. How do you flesh out these things before you start actually coding? For arguments sake, let's say I'm a novice with the MVC pattern, and I wanted to implement such a component/architecture. A naive approach would be to think of: a front controller some abstract action controller some abstract view ... and be done with it, so to speak. But, being more familiar with the MVC pattern, I know now that it makes sense to also have: a request object a router a dispatcher a response object view helpers etc.. etc.. If you map this idea to some completely new component you want to develop, with which you have no experience yet; how do you come up with these sort of additional components without actually coding the thing, and stuble upon the ideas that way? How would you know up front how fine grained some components should be? Is this a matter of disciplining yourself to think it out thoroughly? Or is it a matter of being good at thinking in abstractions?

  • How do I code this relationship in SQLAlchemy?

    - by Martin Del Vecchio
    I am new to SQLAlchemy (and SQL, for that matter). I can't figure out how to code the idea I have in my head. I am creating a database of performance-test results. A test run consists of a test type and a number (this is class TestRun below) A test suite consists the version string of the software being tested, and one or more TestRun objects (this is class TestSuite below). A test version consists of all test suites with the given version name. Here is my code, as simple as I can make it: from sqlalchemy import * from sqlalchemy.ext.declarative import declarative_base from sqlalchemy.orm import relationship, backref, sessionmaker Base = declarative_base() class TestVersion (Base): __tablename__ = 'versions' id = Column (Integer, primary_key=True) version_name = Column (String) def __init__ (self, version_name): self.version_name = version_name class TestRun (Base): __tablename__ = 'runs' id = Column (Integer, primary_key=True) suite_directory = Column (String, ForeignKey ('suites.directory')) suite = relationship ('TestSuite', backref=backref ('runs', order_by=id)) test_type = Column (String) rate = Column (Integer) def __init__ (self, test_type, rate): self.test_type = test_type self.rate = rate class TestSuite (Base): __tablename__ = 'suites' directory = Column (String, primary_key=True) version_id = Column (Integer, ForeignKey ('versions.id')) version_ref = relationship ('TestVersion', backref=backref ('suites', order_by=directory)) version_name = Column (String) def __init__ (self, directory, version_name): self.directory = directory self.version_name = version_name # Create a v1.0 suite suite1 = TestSuite ('dir1', 'v1.0') suite1.runs.append (TestRun ('test1', 100)) suite1.runs.append (TestRun ('test2', 200)) # Create a another v1.0 suite suite2 = TestSuite ('dir2', 'v1.0') suite2.runs.append (TestRun ('test1', 101)) suite2.runs.append (TestRun ('test2', 201)) # Create another suite suite3 = TestSuite ('dir3', 'v2.0') suite3.runs.append (TestRun ('test1', 102)) suite3.runs.append (TestRun ('test2', 202)) # Create the in-memory database engine = create_engine ('sqlite://') Session = sessionmaker (bind=engine) session = Session() Base.metadata.create_all (engine) # Add the suites in version1 = TestVersion (suite1.version_name) version1.suites.append (suite1) session.add (suite1) version2 = TestVersion (suite2.version_name) version2.suites.append (suite2) session.add (suite2) version3 = TestVersion (suite3.version_name) version3.suites.append (suite3) session.add (suite3) session.commit() # Query the suites for suite in session.query (TestSuite).order_by (TestSuite.directory): print "\nSuite directory %s, version %s has %d test runs:" % (suite.directory, suite.version_name, len (suite.runs)) for run in suite.runs: print " Test '%s', result %d" % (run.test_type, run.rate) # Query the versions for version in session.query (TestVersion).order_by (TestVersion.version_name): print "\nVersion %s has %d test suites:" % (version.version_name, len (version.suites)) for suite in version.suites: print " Suite directory %s, version %s has %d test runs:" % (suite.directory, suite.version_name, len (suite.runs)) for run in suite.runs: print " Test '%s', result %d" % (run.test_type, run.rate) The output of this program: Suite directory dir1, version v1.0 has 2 test runs: Test 'test1', result 100 Test 'test2', result 200 Suite directory dir2, version v1.0 has 2 test runs: Test 'test1', result 101 Test 'test2', result 201 Suite directory dir3, version v2.0 has 2 test runs: Test 'test1', result 102 Test 'test2', result 202 Version v1.0 has 1 test suites: Suite directory dir1, version v1.0 has 2 test runs: Test 'test1', result 100 Test 'test2', result 200 Version v1.0 has 1 test suites: Suite directory dir2, version v1.0 has 2 test runs: Test 'test1', result 101 Test 'test2', result 201 Version v2.0 has 1 test suites: Suite directory dir3, version v2.0 has 2 test runs: Test 'test1', result 102 Test 'test2', result 202 This is not correct, since there are two TestVersion objects with the name 'v1.0'. I hacked my way around this by adding a private list of TestVersion objects, and a function to find a matching one: versions = [] def find_or_create_version (version_name): # Find existing for version in versions: if version.version_name == version_name: return (version) # Create new version = TestVersion (version_name) versions.append (version) return (version) Then I modified my code that adds the records to use it: # Add the suites in version1 = find_or_create_version (suite1.version_name) version1.suites.append (suite1) session.add (suite1) version2 = find_or_create_version (suite2.version_name) version2.suites.append (suite2) session.add (suite2) version3 = find_or_create_version (suite3.version_name) version3.suites.append (suite3) session.add (suite3) Now the output is what I want: Suite directory dir1, version v1.0 has 2 test runs: Test 'test1', result 100 Test 'test2', result 200 Suite directory dir2, version v1.0 has 2 test runs: Test 'test1', result 101 Test 'test2', result 201 Suite directory dir3, version v2.0 has 2 test runs: Test 'test1', result 102 Test 'test2', result 202 Version v1.0 has 2 test suites: Suite directory dir1, version v1.0 has 2 test runs: Test 'test1', result 100 Test 'test2', result 200 Suite directory dir2, version v1.0 has 2 test runs: Test 'test1', result 101 Test 'test2', result 201 Version v2.0 has 1 test suites: Suite directory dir3, version v2.0 has 2 test runs: Test 'test1', result 102 Test 'test2', result 202 This feels wrong to me; it doesn't feel right that I am manually keeping track of the unique version names, and manually adding the suites to the appropriate TestVersion objects. Is this code even close to being correct? And what happens when I'm not building the entire database from scratch, as in this example. If the database already exists, do I have to query the database's TestVersion table to discover the unique version names? Thanks in advance. I know this is a lot of code to wade through, and I appreciate the help.

  • Exit code 3 (not my return value, looking for source)

    - by Kathoz
    Greetings, my program exits with the code 3. No error messages, no exceptions, and the exit is not initiated by my code. The problem occurs when I am trying to read extremely long integer values from a text file (the text file is present and correctly opened, with successful prior reading). I am using very large amounts of memory (in fact, I think that this might be the cause, as I am nearly sure I go over the 2GB per process memory limit). I am also using the GMP (or, rather, MPIR) library to multiply bignums. I am fairly sure that this is not a file I/O problem as I got the same error code on a previous program version that was fully in-memory. System: MS Visual Studio 2008 MS Windows Vista Home Premium x86 MPIR 2.1.0 rc2 4GB RAM Where might this error code originate from? EDIT: this is the procedure that exits with the code void condenseBinSplitFile(const char *sourceFilename, int partCount){ //condense results file into final P and Q std::string tempFilename; std::string inputFilename(sourceFilename); std::string outputFilename(BIN_SPLIT_FILENAME_DATA2); mpz_class *P = new mpz_class(0); mpz_class *Q = new mpz_class(0); mpz_class *PP = new mpz_class(0); mpz_class *QQ = new mpz_class(0); FILE *sourceFile; FILE *resultFile; fpos_t oldPos; int swapCount = 0; while (partCount > 1){ std::cout << partCount << std::endl; sourceFile = fopen(inputFilename.c_str(), "r"); resultFile = fopen(outputFilename.c_str(), "w"); for (int i=0; i<partCount/2; i++){ //Multiplication order: //Get Q, skip P //Get QQ, mul Q and QQ, print Q, delete Q //Jump back to P, get P //Mul P and QQ, delete QQ //Skip QQ, get PP //Mul P and PP, delete P and PP //Get Q, skip P mpz_inp_str(Q->get_mpz_t(), sourceFile, CALC_BASE); fgetpos(sourceFile, &oldPos); skipLine(sourceFile); skipLine(sourceFile); //Get QQ, mul Q and QQ, print Q, delete Q mpz_inp_str(QQ->get_mpz_t(), sourceFile, CALC_BASE); (*Q) *= (*QQ); mpz_out_str(resultFile, CALC_BASE, Q->get_mpz_t()); fputc('\n', resultFile); (*Q) = 0; //Jump back to P, get P fsetpos(sourceFile, &oldPos); mpz_inp_str(P->get_mpz_t(), sourceFile, CALC_BASE); //Mul P and QQ, delete QQ (*P) *= (*QQ); (*QQ) = 0; //Skip QQ, get PP skipLine(sourceFile); skipLine(sourceFile); mpz_inp_str(PP->get_mpz_t(), sourceFile, CALC_BASE); //Mul P and PP, delete PP, print P, delete P (*P) += (*PP); (*PP) = 0; mpz_out_str(resultFile, CALC_BASE, P->get_mpz_t()); fputc('\n', resultFile); (*P) = 0; } partCount /= 2; fclose(sourceFile); fclose(resultFile); //swap filenames tempFilename = inputFilename; inputFilename = outputFilename; outputFilename = tempFilename; swapCount++; } delete P; delete Q; delete PP; delete QQ; remove(BIN_SPLIT_FILENAME_RESULTS); if (swapCount%2 == 0) rename(sourceFilename, BIN_SPLIT_FILENAME_RESULTS); else rename(BIN_SPLIT_FILENAME_DATA2, BIN_SPLIT_FILENAME_RESULTS); }

  • Making a app show inside a GUI in Java

    - by José
    Hello. I have one problem I've been dealing with for this week. You see, I'm new to Java, so that's probably it... Anyways, I've started a project out of pure curiosity. I had it done in Java, but in plain CMD-style, which is not very pretty. It calls one of my ten programs, chosen by the user using "Case". Eg.: If you type 1, it will go to program 1. After you finish it, it goes back to selection until the user press 0. After that, I've been trying to make a GUI for it. I've been able to create the selector alone and make it respond to the numbers chosen. If you press 1 and click ok, it will tell you you've chosen program 1. I, however, have not been able to make it run the program. I've been trying to make the program show up in a jPanel, part of the main GUI. I failed miserably. The program runs in separate but I can't make them run together like the CMD one. The apps were made in Eclipse SDK 3.5.2 The GUIs were made in Netbeans IDE 6.8 Here's the code for the GUI only (the prints are in PT-BR, my native language): Main program: /* * To change this template, choose Tools | Templates * and open the template in the editor. */ /* * ProgramasGUI.java * * Created on 31/01/2010, 22:56:19 */ package Main; import Main.Prog1; /** * * @author Zeh® */ public class ProgramasGUI extends javax.swing.JFrame { /** Creates new form ProgramasGUI */ public ProgramasGUI() { initComponents(); } /** This method is called from within the constructor to * initialize the form. * WARNING: Do NOT modify this code.

  • Creative ways to punish (or just curb) laziness in coworkers

    - by FerretallicA
    Like the subject suggests, what are some creative ways to curb laziness in co-workers? By laziness I'm talking about things like using variable names like "inttheemplrcd" instead of "intEmployerCode" or not keeping their projects synced with SVN, not just people who use the last of the sugar in the coffee room and don't refill the jar. So far the two most effective things I've done both involve the core library my company uses. Since most of our programs are in VB.net the lack of case sensitivity is abused a lot. I've got certain features of the library using Reflection to access data in the client apps, which has a negligible performance hit and introduces case sensitivity in a lot places where it is used. In instances where we have an agreed standard which is compromised by blatant laziness I take it a step further, like the DatabaseController class which will blatantly reject any DataTable passed to it which isn't named dtSomething (ie- must begin with dt and third letter must be capitalised). It's frustrating to have to resort to things like this but it has also gradually helped drill more attention to detail into their heads. Another is adding some code to the library's initialisation function to display a big and potentially embarrassing (only if seen by a client) message advising that the program is running in debug mode. We have had many instances where projects are sent to clients built in debug mode which has a lot of implications for us (especially with regard to error recovery) and doing that has made sure they always build to release before distributing. Any other creative (ie- not StyleCop etc) approaches like this?

  • How to install OpenCV 2.0 on win32

    - by Jive Dadson
    I need to install OpenCV on Win32. I do not have it installed currently. I downloaded OpenCV-2.0.0a-win32.exe and ran it. What the heck do I do now? There are no .lib's and whatnot. I found some instructions for building the release using cmake at http://opencv.willowgarage.com/wiki/InstallGuide . I downloaded the latest and greatest cmake, and tried to follow the instructions, but I was guessing. No joy. I specified VC++9 when I did the "configure," but cmake built a VC++ 6 dsw file. No vcproj. I converted the dsw into a vc++9 vcproj anyway, just to see if it would work. Nope. It compiled lots of files, but many failed because it could not find omp.h. Sure enough, it's not there, anywhere. The build log said, 'A tool returned an error code from "Performing Custom Build Step".' I am lost. Ideally, I would like to find a full installation with all the files pre-built for Win32 vc++ 2008. Failing that, I need instructions that even I can follow. Short sentences and small words, but lots of them. Please help! UPDATE: I tried to build just CXCORE. It complained, "cannot open file 'VCOMPD.lib'" There's that OMP again.

  • "Function object is unsubscriptable" in basic integer to string mapping function

    - by IanWhalen
    I'm trying to write a function to return the word string of any number less than 1000. Everytime I run my code at the interactive prompt it appears to work without issue but when I try to import wordify and run it with a test number higher than 20 it fails as "TypeError: 'function' object is unsubscriptable". Based on the error message, it seems the issue is when it tries to index numString (for example trying to extract the number 4 out of the test case of n = 24) and the compiler thinks numString is a function instead of a string. since the first line of the function is me defining numString as a string of the variable n, I'm not really sure why that is. Any help in getting around this error, or even just help in explaining why I'm seeing it, would be awesome. def wordify(n): # Convert n to a string to parse out ones, tens and hundreds later. numString = str(n) # N less than 20 is hard-coded. if n < 21: return numToWordMap(n) # N between 21 and 99 parses ones and tens then concatenates. elif n < 100: onesNum = numString[-1] ones = numToWordMap(int(onesNum)) tensNum = numString[-2] tens = numToWordMap(int(tensNum)*10) return tens+ones else: # TODO pass def numToWordMap(num): mapping = { 0:"", 1:"one", 2:"two", 3:"three", 4:"four", 5:"five", 6:"six", 7:"seven", 8:"eight", 9:"nine", 10:"ten", 11:"eleven", 12:"twelve", 13:"thirteen", 14:"fourteen", 15:"fifteen", 16:"sixteen", 17:"seventeen", 18:"eighteen", 19:"nineteen", 20:"twenty", 30:"thirty", 40:"fourty", 50:"fifty", 60:"sixty", 70:"seventy", 80:"eighty", 90:"ninety", 100:"onehundred", 200:"twohundred", 300:"threehundred", 400:"fourhundred", 500:"fivehundred", 600:"sixhundred", 700:"sevenhundred", 800:"eighthundred", 900:"ninehundred", } return mapping[num] if __name__ == '__main__': pass

  • Help Needed Finding a Programmer

    - by ssean
    Good Morning, I am trying to find a programmer to code a piece of custom software for my business. I plan on using this software to manage my business, and possibly sell it to other companies (in the same industry) at a later date. I've never hired a programmer before, so I'm not sure what to expect or where to begin. I know exactly what features I need, and how I want it laid out, I just need someone who can take my ideas and make it happen. This software will be used to manage customer information, and keep track of orders. What I think I need: * SQL Server or similar database that will be located at our office. * Desktop Application, that connects via LAN to the database server (cannot be browser based) * Multiple User Support (Simultaneous users accesing the system) * Needs to be scalable (currently we have 5 employees, but who knows what the future will bring) * Multi-Platform Support (Windows, Linux) I posted a job offer through elance, which seems to raise more questions than answers. How do I decide what language(s) will work best for my situation? (I have received offers for C#, Eclipse, .NET, Powerbuilder, etc. - I want to make sure that I choose the best one now, so I don't run into problems later) Does the programmer hold any rights to the software? (I plan to offer the software for sale at a later date) Any help or insight would be appreciated, and I'd be happy to clarify anything if it helps. Thanks in advance!

  • Code a timer in a GUI python TKinter

    I need to code a program with GUI in python (I'm thinking of using TKinter, 'cause it's easy, but I'm open to suggestions). My major problem is that I don't know how to code a timer (like a clock... like 00:00:00,00 hh:mm:ss,00 ) I need it to update it self (that's what I don't know how to do) Another question is how do I put a program in the system tray (I don't think it's called like that in Linux) for UBUNTU.

  • Google Streetview under V3 Code having hiccups and delays

    http://new.brocksmeaton.com/showlisting.php/196/-7210-Arbutus-Place-Whytecliff-West-Vancouver-west-vancouver-real-estate The really odd thing is I had this working yesterday and today it's not working. I'm using jQuery UI to switch the tabs on the location map/street view module. I've recently upgraded the Google Maps code as well as the Google Streetview code to version 3. So when I open it in Firefox, with Firebug on, as soon as I switch to the Streetview tab, the navigation and zoom in out controls show, but nothing shows.. and then when I try to drag the map around, it does not move around, but instead, causes errors in Firebug: "too much recursion". So it causes the whole browser to become buggy, slows down, and the errors happen, and nothing shows on the streetview pane. Most of the map loading code is located in inline Javascript on the page itself. Some of the code is under showlisting.js <script type="text/javascript" src="/js/showlisting.js"></script> <script type="text/javascript"> // Call this function when the page has been loaded function loadmap() { var latlng = new google.maps.LatLng(49.374918567425475, -123.28996885871596); var myOptions = { zoom: 14, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById('listingmap'), myOptions); var listingicon = '/images/activehouse.png'; var infowindow = new google.maps.InfoWindow(); homemarker = new google.maps.Marker({position: latlng, map: map, icon: listingicon}); google.maps.event.addListener(homemarker, 'click', function() { infowindow.setContent('<div style="height:80px; width:250px; color:#333;"><p>7210 Arbutus Place<br />Whytecliff, West Vancouver</div>') infowindow.open(map,homemarker); }); } function loadpano() { var latlng = new google.maps.LatLng(49.374918567425475, -123.28996885871596); $('#listingpanorama').slideDown(500, function() { var panoramaOptions = { addressControl:false, position: latlng, pov: { heading: 34, pitch: 30, zoom: 1 } }; var panorama = new google.maps.StreetViewPanorama(document.getElementById('listingpanorama'), panoramaOptions); }); return false; } </script> My old one under GOogle API Version 2 is here FYI if you want to take a look at it: http://demo.brixwork.com/master/showlisting.php/63/1701-388-Drake-Street-False-Creek-North-Vancouver-
