• How do I get the Bake console for CakePHP?

  - by ggfan

  I am having trouble getting the Bake console. I am on windows running xampp. I'm doing the IBM cakphp tutorial. Here is my directory: C:\\ xampp htdocs ibm2(a test project--orginally called cakephp) app cake vendors (etc) It says to To use Bake, cd into the /webroot/app directory and launch the Cake Console: ../cake/console/cake bake. You should be presented with a screen that looks like Figure 2. So I write in my command prompt till I am at: C:\xampp\htdocs\ibm2\app Then I type ../cake/console/cake bake but I get this error: '..' is not recognized as an internal or external command, operable program or batch file. What am I doing wrong? I use the window's command prompt

• Why do so many mathematicians format code so poorly? [closed]

  - by marcog

  I have done a fair amount of programming together with mathematicians. Now I am even teaching some high school kids coming from a mathematics background how to program. Most of these people format their code so hideously it's hard to believe. I've even worked with and taught mathematicians who will fight the auto-indenter! Why is this so common amongst mathematicians? BTW, this is one reason I have started teaching Python. Yet still they find ways other than indentation to produce whacked coding styles!

• Create a complex SQL query?

  - by mazzzzz

  Hey guys, I have a program that allows me to run queries against a large database. I have two tables that are important right now, Deposits and withdraws. Each contains a history of every user. I need to take each table, add up every deposit and withdraws (per user), then subtract the withdraws from the deposits. I then need to return every user whos result is negative (aka they withdrew more then they deposited). Is this possible in one query? Example: Deposit Table: |ID|UserName|Amount| |1 | Use1 |100.00| |2 | Use1 |50.00 | |3 | Use2 |25.00 | |4 | Use1 | 5.00 | WithDraw Table: |ID|UserName|Amount| |2 | Use2 | 5.00 | |1 | Use1 |100.00| |4 | Use1 | 5.00 | |3 | Use2 |25.00 | So then the result would output: |OverWithdrawers| | Use2 | Is this possible (I sure don't know how to do it)? Thanks for any help, Max

• Mysterious logging.basicConfig problem (Python)

  - by Max

  I'm writing a Python script to retrieve data from Flickr. For logging purposes, I have the following setup function: def init_log(logfile): format = '%(asctime)s - %(levelname)s - %(message)s' logging.basicConfig(filename=logfile,level=logging.DEBUG,format=format) I've tested this using the python shell and it works as expected, creating a file if one doesn't already exist. But calling it from within my program is where it stops working. The function is definitely being called, and the logfile parameter is working properly – logging.basicConfig just isn't creating any file. I'm not even getting any errors or warnings. My use of the Python Flickr API may be the culprit, but I doubt it. Any ideas?

• Tutorials for an experienced C# user to learn C++

  - by Tim R.

  Are there any good resources for learning C++ that a C# user could use, which don't require knowledge of C? I have quite a good knowledge of C# via courses in my University's game development program (in a 300 level course right now) but now I need to use C++ for a project. I would use a beginner tutorial but they are so hard for me to follow and learn the basic syntax because they start so slowly. I found a few of tutorials for switching from C++ to C#, but none in the other direction. I do have a little bit of Objective C practice from iPhone programming as well.

• How do I profile memory usage in my project

  - by Gacek

  Are there any good, free tools to profile memory usage in C# ? Details: I have a visualization project that uses quite large collections. I would like to check which parts of this project - on the data-processing side, or on the visualization side - use most of the memory, so I could optimize it. I know that when it comes to computing size of the collection the case is quite simple and I can do it on my own. But there are also certain elements for which I cannot estimate the memory usage so easily. The memory usage is quite big, for example processing a file of size 35 MB my program uses a little bit more than 250 MB of RAM.

• Compiler: Translation to assembly

  - by sub

  I've written an interpreter for my experimental language and know I want to move on and write a small compiler for it. It will probably take the source, go through the same steps as the interpreter (tokenizer, parser) and then translate the source to assembly. Now my questions: Can I expect that every command in my language can be 1:1 translated to a bunch of assembly instructions? What I mean is if I will have to completely throw over the whole input program or if it is just translated to assembly per line. Which assembler should I use as output format?

• How Android 2.2 interacting with Flash 10.1 (how to use flash from my app)?

  - by zxcat

  Hi! I'm searched adobe and android developers sites, but can't find any details on this. Is it possible to use Flash as a part of my app? E.g. like a widget/GUI element? Or it's integrated in browser only and can't be simple accessible? I know, Adobe AIR apps are supported as standalone .apk. So it must be some API/SDK (from Google) to connect with Flash player. Is there any details, how to program it (more clear: launch swf from my app and interact with it)? Thank you!

• How to determine the radius and center of a circle when only three noncollinear points are known?

  - by Bob

  I'm working on a C# program that deals with Oracle Spatial geometry. When circle data is stored in a geometry field only three non-collinear points are stored to represent the circle. The problem is that I need to use this data on a Google Maps web page and need the center point and radius of the circle (since my circle drawing function uses that information). Can anyone help with the math involved and translating said math to C#? I think this page may hold the answer, but I'm having a hard time following it. There are formulas for radius and center given three points, but then they define the variables as matrices and I get lost at that point. How would I solve that in code?

• Which is the future of web development: HTML5 or Silverlight(or other RIA framework)?

  - by Morgan Cheng

  My colleagues have a heated debate on what is the future of web development. One side is supporting HTML5 and the other is supporting Silverlight. There is no conclusion of the debate yet. In my humble opinion as a programmer, HTML5 will not improve programming productivity, while Silverlight will. In my understanding, programmers still need to program in JavaScript to take advantage of HTML5. For Silverlight, we can use C# which is static-type language. A lot of coding defects can be found in compilation time. For HTML5, different browsers might still have different behavior even though there is spec. For Silverlight, generally what works in IE will work the same way in other browsers. Just my thoughts. Any idea on how to choose future direction of web development?

• Get file size of BufferedImage before writing the data

  - by David

  I'm working on a Java program that needs to send an image (preferably in PNG format, though I could perhaps use another format if necessary) over the network. The logical way to do this is, of course, to first send the length of the PNG image data, then the data itself. Problem: I don't see any method in ImageIO or anywhere else that will give me the length of the image data. Does this exist somewhere in the Java 1.6 standard library? I know I could just write it to a ByteArrayOutputStream and get the length of the resulting array, but before resorting that I wanted to make sure I'm not missing something built in. And besides, that makes an extra copy of the image data, which I'd rather not do if it's not necessary.

• Printing python tkinter output

  - by Eric

  I am trying to print the contents of a python tkinter canvas. I have tried using the postscript method of canvas to create a postscript file, but I get a blank page. I know this is because I have embedded widgets, and these do not get rendered by the postscript method. Before I rewrite my program to create a more printer-friendly layout, can someone suggest a way to approach this problem? All of the programming books I have ever read approach the problem of sending output to a printer with a bit of hand-waving, something along the lines of: "It's a difficult problem that depends on interacting with the operating system." I also have a hard time finding resources about this because of all the pages related to printing to the screen. I am using Python 2.6, on Ubuntu 9.04.

• Flash: How to get a list to be processed synchronous instead of asynchronous?

  - by Quandary

  Question: In Flash I have the below function. Now the problem is SaveFurniture, SavePolygons and SaveComments all save to the same XML file. Now SaveFurniture sends JSON encoded data to a ashx handler, which saves it in the xml on the server. The problem is, because flash sends the data asynchronous, the polygons get sent to the polygonsave ashx handler, but before saving of the furniture has completed, thus access error, write process already in progress... // cSaveData.SaveData(); public static function SaveData():void { trace("cSaveData.SaveData"); //NotifyASPXofNewScale(cGlobals.nPlanScale); SaveFurniture(); SavePolygons(); SaveComments(); } What's the best way to process this list, ONE AFTER ANOTHER ? Making a callback in all of them does make the program flow structure very confusing...

• How do you expose a C++ class in the V8 Javascript Engine so it can be created using new?

  - by Steve Hanov

  The official examples of exposing a Point class seem to assume that there will be a fixed number of instances of it in your program. It is not clear how new instances are allocated in the C++ code, when new is called in Javascript. How would you expose a class that can have multiple instances? For example, an Image class: var img1 = new Image( 640, 480 ); var img2 = new Image( 1024, 768 ); img1.clear( "red" ); img2.clear( "black" );

• Can you get the previous value of a variable in Java?

  - by The Special One

  Say way have a variable (let's say String Str) and the value of Str starts of as " " then as some code is running it is set to "test" then somewhere else in the code it is changed again to say "tester". Now in the program I want to find out what the previous value of Str was. Is this possible in Java? So I am saying that the variable gets changed twice, and you want to find out what Str was before it got changed for the second time. So in the example above the latest value of Str would be "tester" but I wanted to find out what Str was before this (assuming you had no idea what it was before it was changed to tester) in this case I would want to be able to find out that Str was "test". Is it at all possible to do this in Java?

• Need help with formulating LINQ query

  - by eponymous23

  I'm building a word anagram program that uses a database which contains one simple table: Words --------------------- varchar(15) alphagram varchar(15) anagram (other fields omitted for brevity) An alphagram is the letters of a word arranged in alphabetical order. For example, the alphagram for OVERFLOW would be EFLOORVW. Every Alphagram in my database has one or more Anagrams. Here's a sample data dump of my table: Alphagram Anagram EINORST NORITES EINORST OESTRIN EINORST ORIENTS EINORST STONIER ADEINRT ANTIRED ADEINRT DETRAIN ADEINRT TRAINED I'm trying to build a LINQ query that would return a list of Alphagrams along with their associated Anagrams. Is this possible?

• Fake Mouse (C# or C++)

  - by Hidden

  I need a way to fake that a mouse is connected. The problem: My HTPC (Windows 8) has no mouse connected and I wrote a program to simulate mouse input using my Xbox 360 Controller. This works just fine, the only problem is, that there is no cursor visible (I can move it, but I cant see it). My guess is, that Windows doesn't show a cursor when there is no mouse connected, so I need a way to pretend that a mouse is connected to the PC. Of course, if you know another way to make the cursor visible I would gladly take this solution as well. Regards, Hidden

• How can I hide a property from going into the form designer file?

  - by user460334

  I am working in VB.NET 2010 Framework 2.0. I don't want to allow some properties from going into form's designer file but the those properties will present on the form(property grid). The behavior of these properties will be same always. I used the following code: <DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> Public Property GradientBegin() As Color = Color.Red But the problem I am facing is that - on the property grid after changing the "GradientBegin" color to other than RED and compiling the program, it is replacing the new changed value to RED again. So I am not able to change the color actually. How can I achieve this? Thanks for any reply in advance.

• How do game trainers change a address in memory thats dynamic?

  - by GameTrainersWTF

  Lets assume i am a game and i have a global int* that contains my health. A game trainers job is to modify this value to whatever in order to achieve god mode. I've looked up tutorials on game trainers to understand how they work, and the general idea is to use a memory scanner to try and find the address of a certain value. Then modify this address by injecting a dll or whatever. But i made a simple program with a global int* and its address changes every time i run the app, so i don't get how game trainers can hard code these addresses? Or is my example wrong? What am i missing?
