Dropbox API via cron
I've written a simple webapp that reads from dropbox folder. It works from the browser. Now I want to automate with a cron job. With a cron, it stops at redirect. How can the dropbox api calls (file read) be automated through cron? Thank you, Joseph

Queue Priority in CruiseControl.NET
In my build configuration I have multiple project queues: Queue1, Queue2, ... Queue(N) I want to configure the build where I can set the priority of when each queue builds: Queue1 = Priority of 2, Queue2 = Priority of 1 ... which produces the queues being built in the following order: Queue2, Queue1 ... How can I accomplish this in CruiseControl.NET?

Are the old days of code injection over?
I was wondering since all updated operating systems guard against stack and heap type overflows via ASLR, Canary Checks, and other such methods, are memory corruption exploits still prevalent? Given that the administrator of the system is competent and protects the system from brute force or libc attacks, I honestly can't see many other ways. They only thing that I can possibly imagine for someone to attack a system is to overwrite function pointers on the stack but thats about it. Maybe if someone found a clever way of predicting random numbers, the schemes that rely on random results could be defeated, however it seems unlikely. It seems the only way to exploit someone else's system given now a days is to trick root or the admin into installing your software. Are the old days of code injection over? I'm at this from the perspective of breaking updated protected systems.

Class Design for delegate, outlets, and mouse events
Here's a simplification: I have an application with several buttons. If it is the first time the application is launching, I want to do some special things. In my AppController class, which is a delegate of NSApp, I use the delegate method -applicationDidFinishLaunching: to perform the test. After I've detected that it is the first time, I first want to access some IBOutlets. Then, I'd like to be able to get mouse events for each button, so that I can do other things. I can't figure out want to do with the classes. I'd like to make a new class (FirstLaunch) for the first launch, but I'm not sure what to call from AppDelegate. Also, to get mouse events, shouldn't I be a sublass of the buttons, and considering that I have multiple buttons, I'm confused. I could probably tackle these issues one-by-one, but taken all together, they're confusing me. Broken down, I need to access & manipulate IBOutlets I have set in IB, determine when buttons are clicked (and which button was clicked). I'd like to be able to do this from another class so as to not clutter up the AppDelegate. Thanks for the help!

Changing your online repositiory from another computer
I created an online repository on github.com I was adding/removing/modifying files on that repository normally from a computer i was using. Now, i am using a different computer and i do not have the original local repository that was stored on the other computer i was using. So, I created a folder whose name is the same as the name of the repository and i put the files inside that folder along with git of-course. What I wanted to do is to modify my online repository but i have problems in doing that. Mainly that i could not push. git it gives an error back which i could not resolve. I searched online on how to resolve the problem. Of-course i found solutions but non-of them worked. What one should do in-order to modify an an online repository form another computer?

Generic Question: Thoughts on soft keyboard UI for mobile devices
Yo, so I was curious about your thoughts about your preferences on soft keyboards for mobile devices. Are there any particularly innovative ones that you like? By the way, my ulterior motive for asking this question was to look up one particular instance that I heard about, oh 10-ish months ago. Basically, you type with your finger constantly on the keyboard. Based on your direction changes and speed, the keyboard is supposed to be a much better predictor of keys. I'd really appreciate it if you Pardon me for using this as a search for information, but it apparently made a much smaller smash in the gadget news sources, and implementations haven't come out yet.

What's the best POCO status tracking strategy? (EF)
So I was reading about Entity Framework and based on my agile development scenario I decided to go with POCO objects. But now I'm having some extra problems I don't know how to get away with. I'm working with RIA services and Silverlight so when I'm going to Save an object of the server side I have to attach the object to an `ObjectContext`. The thing is that I must then change the `ObjectState` to Added or Modified. So my question is what's the best approach to really know what state to change it to. I saw in [Julia Lerman][1]'s book that she uses a `State` attribute in her POCO objects and she takes care managing that state on the client side before sending the object to the server. That state then is used to change the real EntitySate once attached. I've also seen other samples where the Insert implementation checks on the Key of the Entity (object) to know whether it is new or not. For example, if `ProjectId` in my Project entity is 0 (zero) I know it has to be a new object. To be honest I don't like any of those approaches because in both cases my developers have to do some extra-work to actually save the object. I'd like the know pros and cons of both solutions and hopefully a new (better) solution I'm still not seing. [1]:http://www.learnentityframework.com/

Using LINQ to XML to traverse an HTML table
So I can easily use LINQ to XML to traverse a properly set-up XML document. But I'm having some issues figuring out how to apply it to an HTML table. Here is the setup: <table class='inner' width='100%'> <tr> <th> Area </th> <th> Date </th> <th> ID </th> <th> Name </th> <th> Email </th> <th> Zip Code </th> <th> Type </th> <th> Amount </th> </tr> <tr> <td> Data </td> <td> Data </td> <td> Data </td> <td> Data </td> <td> Data </td> <td> Data </td> <td> Data </td> <td> Data </td> </tr> <tr> <td> Data </td> <td> Data </td> <td> Data </td> <td> Data </td> <td> Data </td> <td> Data </td> <td> Data </td> <td> Data </td> </tr> </table> Essentially, there can be an endless number of rows, I want to be able to go row-by-row to check the data accordingly. Can anyone point me in the right direction? Should I be using tools other than LINQ for this?

Engine Scripting and Class Structure
I've started to code a 2d JRPG engine in C#/XNA and i have some questions about class structure and game events. In a 'game maker' type environment you have a game script which runs events and so on based on user input. This is usually not OO and has no reference to classes and so on. Now in my own engine what is the best way to code game events? Suppose you interact with an NPC on screen, how would that event be handled in an OO language? I assume I would have an event within the character class and I assume that event would be assigned to in the section which loads the map but where would that event be linked to? Which class would contain the event logic? class Character { ... public delegate void InteractionEventHandler(object sender, EventArgs e); ... public event InteractionEventHandler Interact; ... } class Map { public Map(){ ... //add a new character to the NPC collection newchar.Interact += ??? ... } }

List of identifiers of ActionScript 3.0 in Adobe Flash
I`m looking for a list of identifiers of ActionScript 3.0 . In Adobe Flash, it is possible to change the identifier`s color. I want to do the same in notepad++ in langs.xml file. All I need is the list and it seems hard to find one.

run for loop limited iterations in python
I have an extremely large list of objects and I need to find all that have the identical attribute (any_object.any_attribute) and then append them to a new list. So I have pre-sorted them and run a binary search algo. I have found the object with the matching attribute but the problem is that there are more than one such objects (they are neighbours) but I can't figure out a clean way of running a loop on these contiguous objects so that they all can be appended. My code is pasted below. low = 0 high = len(sortedObjects) while low < high: mid = (low + high)/2 if sortedObjects[mid].attr < desired_attr: low = mid + 1 elif sortedSamples[mid].attr > desired_attr: high = mid else: newList.append(sortedObjects[mid]) break So I need to write some new code in the last else block which would iterate over all the objects with the same attributes and append them. Sounds like a for loop would be needed but is it possible to run a for loop for limited iterations, like in C? I do not want to iterate over the whole list as that would be slower and one of the requirements of this script is that it has to be fast and efficient. It will be run on really large sets of data and we are looking at execution times of 10-12 hrs. Thanks in advance!

webcam access using opencv with processing in an applet or application
I made a small sketch with processing using opencv to face detect and track. But when I export as an application and start it nothing happens, same as an applet. First I exported the applet and thought this must be a security issue, and struggled with some hack for processing to sign your java applet. http://processing.org/hacks/hacks:signapplet With no luck I thought I would atleast be able to run it as an application but no success. Anyone know what to do?

trouble with Nivo slider (stays on one slide)
I have Nivo slider installed and I am using Drupal 7 with http://drupal.org/project/boldy. I installed Nivo slider, and I created a /sites/all/libraries/nivo-sider folder, extracting the js nivo slider libraries there. I have Nivo implemented in my theme in the recommended area for slider. There are 6 slides and it wont cycle. It does the transition and thats it, it renders the same image over and over. Any pointers would be appreciated. I would also be interested in a better banner component if Nivo is not the best choice.

List fonts used by a Word Document (faster method)
I am working on process for validating documents to make sure that they meet corporate standards. One of the steps is to make sure that the Word document does not use non-approved fonts. I have the following stub of code, which works: Dim wordApplication As Word.ApplicationClass = New Word.ApplicationClass() Dim wordDocument As Word.Document = Nothing Dim fontList As New List(Of String)() Try wordDocument = wordApplication.Documents.Open(FileName:="document Path") 'ive also tried using a for loop with an integer counter, no change in speed' For Each c As Word.Range In wordDocument.Characters If Not fontList.Contains(c.Font.Name) Then fontList.Add(c.Font.Name) End If Next But this is **incredibly** slow! Incredibly slow = 2500 characters/minute (I timed it with StopWatch). Most of my files are around 6,000 words/30,000 characters (about 25 pages). But there are some documents that are in the 100's of pages... Is there a faster way of doing this? I have to support Office 2003 format files, so the OpenXML SDK isn't an option.

Trying to do something with the api of twitter, i got a problem... i use this url: https://api.twitter.com/1/statuses/oembed.json?id=<id_of_tweet>&align=center i do file_get_contents to get the json and insert to BD, before insert, i see the json have slashes and can do json_decode, but, once the string was inserted, the slashes disappear! then i cant do json_decode when the query from sql, what can i do?? thank you!

Rewrite parts of old content to target new ads?
I have a website with a lot of visitors, but very poorly targeted ads. 90% of traffic comes from alt text in images. The theme is celebrities. Here's my question: Can I change / add / rewrite content to target new types of ads; content as old as 6 + months? As of now, the posts are merely short snippets on a little bit about each celebrity; the images (alt text) bring the traffic. I would want to rewrite content on each page to use a lot of plastic surgery related keywords. This would obviously target a niche and much higher paying ads. *Since the traffic isn't really coming from the text to begin with:* - Would this cause a loss in traffic? - Would this target new ads and if so how long would it take for changes to take place?

What is a sensible prime for hashcode calculation?
Eclipse 3.5 has a very nice feature to generate Java hashCode() functions. It would generate for example (slightly shortened:) class HashTest { int i; int j; public int hashCode() { final int prime = 31; int result = prime + i; return prime * result + j; } } This seems fine but for the choice 31 for the prime. It is probably taken from the [hashCode implementation of Java String][1], which was used for performance reasons that are long gone after the introduction of hardware multipliers. Here you have many hashcode collisions for small values of i and j: for example (0,0) and (-1,31) have the same value. I think that is a Bad Thing(TM), since small values occur often. For String.hashCode you'll also find many short strings with the same hashcode, for instance "Ca" and "DB". If you take a large prime, this problem disappears if you choose the prime right. So my question: what is a good prime to choose? What criteria do you apply to find it? [1]: http://stackoverflow.com/questions/299304/why-does-javas-hashcode-in-string-use-31-as-a-multiplier

What are the security risks in using cross-domain XMLHttpRequest?
In many places I've seen people have talked about the Cross-Domain XMLHttpRequest, which is not possible, due to some **security reasons**. However, I haven't found a post indicating what those **security reasons** actually are? People have mentioned that JSONP is one of the good alternatives. Another alternative would be to use `Origin` and `Access-Control-Allow-Origin` headers. However, I just want to know what security problems can be raised due to cross-domain XMLHttpRequest usage?

Open Excel sheet in share point page/webpart itself
In share point 2010, I would like to have an excel sheet(2007) in sharepoint site, where the Excel sheet should be displayed in the site itself (Possibly a webpart). **And the users should able to edit the excel sheet from webpart itself** (No need to open the Excel sheet in seperate MS Excel). I meant adding new rows of data and editing existing the rows. I come across various posts regarding the above issue, [like this][1]. [1]: http://www.learningsharepoint.com/2010/10/25/create-excel-web-access-web-part-in-sharepoint-2010-tutorial/ How ever I am unable to get the category 'Office Client Applications' under insert webparts. Please help me on this. Can anyone please give me a suitable link or tips for achieving the above? Many Thanks !!

Can I set a custom function that will alter the color of a display list in OpenGL?
I have geometry stored in a display list, but I'd like to be able to draw the same display list with different "tints" on them. For example, if I had a black and white skull in a display list, I'd like to set a red tint and draw a skull, then set a blue tint and draw the skull. If I can get the RGBA values I know exactly how to transform them, but I'm not sure where I can intercept them. Currently the display lists do not contain textures, but they probably will in the future so it would be good if the answer works with or without textures.

Getting Stack overflow with GNU CLisp (Windows)
I'm getting "Program stack overflow RESET" message while running my program. So I set added a counter to see how many times I'm recursively calling the main function in my program. Turns out that it is around 30,000 times and the data I'm stacking are lists of length around 10 elements, which I think are not so many. My question is whether this amount of recursive call and memory usage are common or not, or is it more likely that I'm doing something wrong? I checked the resource manager of vista and found the memory only grew for like 1MB for lisp.exe process. And how do I adjust the stack overflow limit of CLisp?

Java (conditional operators)
***Here is the deal. I am working on a project for my into to Java class. I am familiar with a few other languages so I do understand basic coding. However, I am very much so a java noob. Please forgive me if this is a very simple problem to solve. I have written the program several time but talking with my professor he is not satisfied. The program I have written perform exactly what is required but not in the way he wants. I will first display the programming assignment then the code I have written. I understand how to write the control class but I am having problem with the object class.*** **Here is my programming assignment:** Write a program to control a bread machine. You should ask the user to specify: The type of bread (white or sweet), The size of the loaf (normal or double), and The manner of baking (automatic or manual). The following table details the time chart for the machine for each bread type. Since we don't really have a bread machine to control, you should instead display an output line for each step of the process. If the loaf size is double, increase the baking time by 50%. If baking is manual, stop after the loaf-shaping cycle and instruct the user to remove the dough for manual baking. Operation White Bread Sweet Bread -------------------------- -------------------------- -------------------------- Primary kneading 15 minutes 20 minutes Primary rising 60 minutes 60 minutes Secondary kneading 18 minutes 32 minutes Loaf shaping 2 seconds 2 seconds Final rising 80 minutes 80 minutes Baking 45 minutes 35 minutes Cooling 40 minutes 40 minutes Specific Instructions Your program will consist of 2 classes: a control class (named BreadControl) and an object class (named BreadMachine). When you begin, create the outlines of the 2 classes. Initially, the BreadControl class should include the class definition and the main method definition (just the signatures, braces, and class and method comments). This class requires only a single method, which is main(). The BreadMachine class should "represent" a bread machine. Begin with the class definition and definitions for any methods that might appear obvious (although this may change as you work through this). This class will have multiple methods, including both public and private methods that work together to solve the problem of managing a BreadMachine. Working top down, develop the algorithms that you will need to accomplish this program. You should work this out in externally to the java program (in pseudocode, for example). Determine the major tasks first. Then work out the subtasks that each will need to accomplish. There should be multiple methods in the BreadMachine class. (Some should be public, and others should be private.) For example, each step of the bread making process should be in its own method. As you work, think about the variables, variable types, constants, and object references you will need to make this work. Declare these variables, constants, and references at the beginning of the BreadMachine class. If you are including constants, declare them together at the end of the declarations section. The BreadMachineclass should have no System.out.println() [or print()] statements. Nor should the BreadMachineclass have need of a Scanner or Keyboard. Create a user-interface for your program. This should be in the BreadControl class. (All user interaction should be here). Provide an attractive greeting and then ask the user What type of bread they intend to make, Whether they are making a double loaf, and Whether they are going to manually bake the bread. An example of what the input should look like can be found in this document. Using these values, create the BreadMachine object and run its starting method (I would recommend starting with a method called bake() that returned the String to be printed.) The values sent to the BreadMachine should be stored in that object as instance (class or global) variables. You should use boolean variables (true/false) to store the double loaf and manual bake values. Once you are certain that your algorithms are correct (desk check this first!), enter it into your java program into the appropriate method(s). The BreadMachine object should return a String that details the steps followed to bake the type of bread required. ***Here is the code for my method. Be aware that this is the format required of me, So please do not say I could do it in a much different way. I am simply trying to figure out why this does not work since I did a majority of this with my professor:*** public class BreadMachine { private double time; private String manner; private String result; private String size; private String type; /** * *Constructor * * * */ public BreadMachine ( String t, String s, String m )// constructor { manner = m; size = s; type = t; } // end constructor // instantations public String bakeBread() { result = doStageOne(); result += doStageTwo(); return result; } //---------------- private methods ------------------- /** * * * * */ private String doStageOne() { result = doPrimaryKneading(); result += doPrimaryRising(); result += doSecondaryKneading(); result += doShaping(); return result; } private String doPrimaryKneading() { time = type == ('w') ? 15 : 20; result = "Primary Kneading (" + time + "minutes )"; } private String doPrimaryRising() { time = 60; result = "Primary Rising (" + time + "minutes )"; } private String doSecondaryKneading() { time = type == ('w') ? 18 : 32; result = "Secondary Kneading (" + time + "minutes)"; } private String doShaping() { time = 2; result = "Shaping (" + time + "seconds)"; } private String doStageTwo() { String result; result = doFinalRising(); result += doBaking(); result += doCooling(); return result; } private String doFinalRising() { if ( isManual() ) { result = "Remove for Manual Baking"; } else { time = 80; result = "Final Rising (" + time + "minutes)"; } } private boolean isManual() { boolean response = false; if ( method.CharAt == 'm') response = true; return response; } private String doBaking() { if ( isDouble()) { time = type == 'w' ? 67.5 : 52.5 ; result = "Shaping (" + time + "minutes)"; } else{ time = type == 'w' ? 45 : 35; } result = "Shaping (" + time + "minutes)"; } private boolean isDouble() { boolean response = false; if ( method.CharAt == 'd') response = true; return response; } private String doCooling() { time = 40; result = "Cooling (" + time + "minutes)"; } }

This list is focused on web development atm, but I believe for the most part, it applies to application programming in general. I'm asking for the community to contribute and critique my list, I'll be updating the list as I get more suggestions from the community. For example: - Security and Stability - Authentication(Login) - Password Reset - Hashed and Salted Passwords - Authorization(Role Based Access) - XSS Prevention - Dual Firewall(public facing/private facing for database) - SQL Injection - Data Integrity - Data Redundancy . - Scalability - Clustering - Caching - Import/Export - Reporting(Performance[speed]and Usage[page hits]) . - Testing - Load Testing - Unit Testing - Performance Testing - Error Logging . - Others - Localization - Configuration Management - Searching - Reporting(according to business need)

Django: what is the most appropriate way to provide administrators with the ability to change small snippets of text
Using Django, what is the most appropriate way to provide administrators with the ability to change small snippets of text, for example in one of my sites there is a small piece of text on the front page I would like the administrator to be able to easily change in the backend, however I do not want to create a whole new app or model because then they would be able to create more than one area of text in this way, but I only want it to show up in one place on the homepage. Any advice?

Django: what is the most appropriate way to provide administrators with the ability to change small snippets of text === Using Django, what is the most appropriate way to provide administrators with the ability to change small snippets of text, for example in one of my sites there is a small piece of text on the front page I would like the administrator to be able to easily change in the backend, however I do not want to create a whole new app or model because then they would be able to create more than one area of text in this way, but I only want it to show up in one place on the homepage. Any advice?

Good tool for system design in Java/Eclipse?
Does anyone know of a good tool for laying out class diagrams and the like for eclipse? Preferably soemthing that will let me draw up the relationships between the classes/interfaces and will then generate stub code for me to fill in. I've just been handed a 288 page API doc and told to implement it in Java and I want to make sure I have a good design before I start writing code.

Apache sudoers access
I am making a system call from php which is `sudo /usr/bin/perl -pi -e 's/foo/bar/g' /tmp/newxml.xml`; which works fine in php cli. But would not work in php via browser, because apache does not have required execution permissions. How do I make apache a sudoer to allow to run only /usr/bin/perl ? I understand that will have to edit /etc/sudoers to do this, but I am not sure how its to be done. Any pointers? I am running RHEL 5.5

How to restore the information_schema database with a backup
I have a backup from a WAMP server MYSQL database from home and I need to install it on my work WAMP setup. Here is the phpmyadmin message: SQL query: -- -- Database: `information_schema` -- CREATE DATABASE `information_schema` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; MySQL said: #1044 - Access denied for user 'root'@'localhost' to database 'information_schema' The information_schema database appears to be locked and the restore fails in phpmyadmin. In the MYSQL Workbench it carries on through the backup ignoring the "access denied" messages but crashes halfway through. I have tried removeing the database_schema lines in the sql file but it just looks like a mess of text and can't figure out how to remove it. Another thing is will I actually need it? Or can I remove it. I'm not too sure what information is stored there. Thank you.

javascript simple while loop not looping through array.(should be easy)
Ok so this is my dumb problem. im here learning and...ive been looking at this for a while and i dont understand. i have an array with some values that are fed via an object. like so: function blogObj(name,date,user_entry){ this.names = name; this.dates = date; this.blog_entry = user_entry; this.propsComb = this.names + this.dates + this.blog_entry; } var blogRun = [ new blogObj("name ", "something ", "something "), new blogObj("name ", "something ", "something "), new blogObj("name ", "something ", "something "), new blogObj("name ", "something ", "something "), new blogObj("name ", "something ", "something "), ]; var i=0; var mssgs = ""; now when i loop through it like this with this doc.write to test: function hmm(){ while(i < blogRun.length){ mssgs = blogRun[i].propsComb + '<br/>'; document.write(mssgs); i++; } } i get all the values i need which are name something something x5 as per the loop and the values of the array. so essentially it works. now when i replace the `"document.write(mssgs)"` with document.getElementById('showMore').innerHTML = mssgs; making it this function hmm(){ while(i < blogRun.length){ mssgs = blogRun[i].propsComb + '<br/>'; //document.write(mssgs); document.getElementById('showMore').innerHTML = mssgs; i++; } } it only shows me the last value of the array. it doesnt loop for the rest of the arrays values. all im doing is replacing the .write with getElementById etc.. any ideas? thank you in advance.

Github workflow for single developer
I would like some feedback on my git workflow because this is my first use of it and despite reading various articles and Stack Overflow questions, I'm not sure that my process is correct. This is my current workflow (note that I am using the Github for Windows application for all of my git interactions): 1. Decide what the next feature is that I'm going to implement. 2. Create a branch with a suitably descriptive name for the feature. I do this by clicking on the branch button in Github for Windows and typing a new name. 3. Write some code. 4. Commit those changes to my new branch. 5. Write some more code. 6. Commit those changes to my new branch. 7. I've finished implementing the feature so I want to merge my changes back to the master branch. So I click on the 'manage' button underneath the branch heading. 8. Merge the new branch into the master branch. 9. Delete the new branch. I am quite happy with the process up until step 7 at which point I am a little confused. I think my confusion lies in the fact that I'm trying to use the Github for Windows application rather than using the command line. The application does seem to make things easier but there is a bit of a disconnect in my understanding between some of the commands/instructions I see mentioned and the actions you would take in the application. Let me ask some specific questions: 1. Is my workflow actually correct? If not, what is wrong with it and how can I improve it? 2. Should I be "publishing" my changes to the new branch? My understanding is that this is the equivalent of doing `git push` at the command line. Is that true? If so I think I would only want to do that when I am either finished implementing the feature or it is in a decent state? 3. Should I be deleting the branch when I have merged it into the master branch or should it be left around forever? 4. Do I need to publish the master branch when I have completed the merge or is this implicit? 5. I am sometimes unable to perform the merge and get this error message: > Unable to merge > > Failed to merge 'test' into 'master'. You might need to open a shell and debug the state of this repo. When this occurred before, I was able to change to the master branch and merge the new branch into the master branch however that no longer works. No matter which branch I am in, I cannot merge the two branches. Both are in sync and I've published all the changes from my test branch. What should I be typing in the shell to find out why I can't merge the branches? For reference, these are the main links that have prompted my process: 1. [Scott Chacon on the workflow at Gitub][1] 2. [Git workflow for a single developer on a local repository][2] 3.

How to secure Windows machine in LAN for PHP running on APACHE?
I have installed my PHP scripts which runs over Apache server in a Windows machine in my office LAN network. It is an internal contest application. Now I want to secure the machine from all sort of intrusions and I would like to log all the intruder's details and what sort of intrusion they have tried. Is it possible to implement through code or is there any existing tool to implement these functions? I know that there are options to get external user's data like $_SERVER['REMOTE_ADDR'], $_SERVER['HTTP_REFERER'], $_SERVER['HTTP_USER_AGENT']. I have a little script for tracking these details. And many of the ports are closed and I am running an AV in it for the purpose. These data will not be enough to get the intrusion type that they have attempted. I want to make the system more secure from all sort of vulnerability and attacks. Can any one point me to a right tool?

Wix Shortcut Arguments Issues
I have a strange issue with Wix I'm creating a shortcut to a config tool for a windows service. I want to pass the config file for the windows service as an argument to the config tool. Thus I have a component that installs the windows service, this works fine and another one that installs the config tool.

Required Explanation for a program in C
I am reading the book by kerninghan Ritchie Edition 2.... It contains a code function on getch(), ungetch(), getop()......... I am not able to understand the stuff..... and I feel that it is bit incomplete also...... I am posting the question here... Please give few examples to make this code look pretty easier...... If there is any correction in the programm,, then please let know.... Thankss..... #include <stdio.h> #include <ctype.h> #define BUFSIZE 100 char buf[BUFSIZE]; /* buffer for ungetch */ int bufp = 0; /* next free position in buf */ int getch(void) /* get a (possibly pushed-back) character */ { return (bufp > 0) ? buf[--bufp] : getchar(); } void ungetch(int c) /* push character back on input */ { if(bufp >= BUFSIZE) printf(" ungetch too many characters\n"); else buf[bufp++] = c; } /* getop: get next character or numeric operand */ int getop(char s[]) { int i, c; while ((s[0] = c = getch()) == ' ' || c == '\t'); s[1] = '\0'; if(!isdigit(c) && c != '.') return c; /* not a number */ i=0; if(isdigit(c)) /* collect integer part */ while(isdigit([s++i] = c = getch())); if(c == '.') /* collect fractional part */ while(isdigit(s[++i] = c = getch())); s[i] = '\0'; if (c != EOF) ungetch(c); }

Apache reverse proxy for several Jenkins CI and Nexus Maven repositories
New Note 130 Hello, I am trying to setup a front-end (reverse proxy) for several Nexus and Jenkins CI servers using Apache httpd and need some help. We have URLs like- > abc.internal.net:8080/ > def.internal.net:9000/jenkins/ > ghi.internal.net:8080/jenkins/ > jkl.internal.net:8081/nexus/ > foo.internal.net/nexus/ I would like each of these to be setup behind the FE reverse proxy so as to have something like- > scm.internal.net/abc-jenkins/ > scm.internal.net/def-jenkins/ > scm.internal.net/ghi-jenkins/ > scm.internal.net/jkl-nexus/ > scm.internal.net/foo-nexus/ Some of the services use root context. Could these be forced into arbitrary web context? I have very limited knowledge of Apache httpd so some real configs would help immensely. Most of these services need URL, content and CSS fixing in the response. If this could be done without changing the existing web context on the severs that these services are running, that would be awesome. Also, I need soft landing on these changes so legacy URL continue to work for few weeks as developers and automation transition to the new scheme. Is this asking for too much? Thanks in advance.

Salvage a nice mobile phone to learn embedded programming?
I have a Galaxy S II with a wrecked screen. I was wondering if the internals could be salvaged as a tool to teach myself embedded programming. I know C and enough x86_64 ASM that I would be comfortable taking on ARM assembly. What would the development environment / set up be like? Would I use the USB connection or is there a more direct way to connect the phone to the computer? Would I need to prepare the phone in some way? Let's say I wanted to write a boot loader for it, are there any good resources of where to start? Is the phone too much of a black box, should I get a board with more documentation than that? Or alternatively, why this is a terrible idea. Would all the drivers be too difficult to deal with if I wanted to use things like the camera? Thanks for the help. I have no idea where to start a project like this.

Object assignment in Ruby
Coming from a c++ background I'm curious about object assignment in Ruby. What considerations (if any) should be made for the following object assignments: class MyClass attr_accessor :a, :b def initialize(a, b) @a = a @b = b end def some_method puts "#{self.a} #{self.b}" end end m = MyClass.new("first", "last") n = MyClass.new("pizza", "hello") q = n q.some_method

RESTful web service and delta updates - advantages and disadvantages
Our front-end developers have requested that the RESTful Java web services to support delta queries. The use case for this is to handle periodic ajax refresh of the screen to bring in new data (deltas). I can see a few advantages of this: - Makes front-end logic simple (i.e. no complicated deduping logic) - Reduce network traffic (i.e. response size is smaller) However, there are some concern as well: - supporting delta will require the service to be stateful, which impact scalability - heavy use of caching (results cached per user per query, to determine the delta) - heavy processing on the server My questions are: - Are there additional advantages to this approach? - What's a good implementation to for delta queries that would eliminate some of the disadvantages (you can assume we are welling to drastically refactor our code) - Does the benefit justify the trade-off?

Trying to insert values into a table cell, some values coming out to undefined
I want to have array values populate a table when I run the program and it all works fine except that 3 of the arrays I had have to be combined into different rows for one column. Basically what happens is the index value keeps coming out to undefined and it messes up the whole program. If any clarification is needed please ask and I'll try my best to explain further. // constants var colCount = 7; var rowCount = 7; // input data var id = new Array("1022", "1112", "1230", "554", "1355", "1600"); var title = new Array("Prof.", "Prof.", "Prof.", "Prof.", "Asst. Prof.", "Asst. Prof."); var name = new Array("Catherine Adler", "Michael Li", "Maria Sanchez", "Robert Hope", "Wayne Li", "Kate Howard"); var position = new Array("Department Chair", "Asst.

Commentor get remove comment options only on their comment PHP/MySql
So I have this table and two sql statements. I want to give commentor 3 from the first query, the ability to remove their comment by using $CommentorProfOwnerOpts, which appears in the comments part being pulled out from the second query. What happens now is that commentor 2 also gets the $CommentorProfOwnerOpts, when only commentor 3 should get them and ONLY on their comment. comment_id | comment_title | commentor_id | profile_owner_id ------------------------------------------------------------- 4 Title 1 2 1 5 Title 2 3 1 //Commentor 3 $commentor = mysql_query("SELECT commentor_id, comment_id FROM comments WHERE commentor_id=3 AND profile_owner_id=1"); $count = mysql_num_rows($commentor); if ($count > 0) { while($row = mysql_fetch_array($commentor)){ $commID = $row["comment_id"]; $CommentorProfOwnerOpts = '<span id="remove-'.$commID.'">Remove Comment</span>'; } And here are the comments: //All Comments for profile owner 1 $comments = mysql_query("SELECT comment_id, comment_title FROM comments WHERE profile_owner_id=1"); while($row = mysql_fetch_array($comments)){ $comment_id = $row["comment_id"]; $comment_title = $row["comment_title"]; $CommentorProfOwnerOpts = '<span id="remove-'.$comment_ID.'">Remove Comment</span>'; $comments .= '<div id="$comment_id" class="comments"> '.$comment_title.' '.$CommentorProfOwnerOpts.' </div>' } The issue is that I can't figure out how to have each commentor get the remove option $CommentorProfOwnerOpts, appear only for their own comment, and not on another comment. How can I fix this?

My window says "android application project" and in the book it says "android project" and so when i click on it to proceed, my next window is different to the one in the book. Does anyone know why this is? and how i may be able to fix it? regards

Why aren't parent constructors being called?
I added in `parent::__construct();` to the constructors of table and bookmark in order to get this code to work. Why are they not called automatically? If I create an object of type bookmark `$obj_ref_bo = new bookmark();` should not bookmark also create objects from each of its parent classes (besides abstract classes). The call chain is bookmark->table->database(abstract)->single_connect /*single_connect*/ class single_connect { protected static $_db_pointer = NULL; private function __construct() { $this->_db_pointer = mysql_connect(DB_HOST, DB_USER, DB_PASS); mysql_select_db(DB_DATABASE); } public static function get_connection() { if(self::$_db_pointer == NULL) { return new self(); } else { echo "Error:only one connection"; } } } /*database*/ abstract class database { protected function __construct() { single_connect::get_connection(); } static protected function query($query) { $result = mysql_query($query) or die(mysql_error()); return $result; } } /*table*/ class table extends database { public $_protected_arr=array(); protected function __construct() { parent::__construct(); self::protect(); } protected function protect() { foreach($_POST as $key => $value) { $this->_protected_arr[$key] = mysql_real_escape_string($value); } } } /*bookmark*/ class bookmark extends table { function __construct() { parent::__construct(); $this->start(); } function start() { if(self::test()) { self::insert(); } else { return 1; } } function test() { if(self::test_empty()) { return 1; } else { return 0; } } function test_empty() { if(text::test_empty($this->_protected_arr)) { return 1; } else { return 0; } } function insert() { $url = $this->_protected_arr['url']; $title = $this->_protected_arr['title']; $email = $_SESSION['email']; database::query("INSERT INTO bo VALUES ('$title', '$url', '$email')"); } }

Why aren't parent constructors being called? === I added in `parent::__construct();` to the constructors of table and bookmark in order to get this code to work. Why are they not called automatically? If I create an object of type bookmark `$obj_ref_bo = new bookmark();` should not bookmark also create objects from each of its parent classes (besides abstract classes). The call chain is bookmark->table->database(abstract)->single_connect /*single_connect*/ class single_connect { protected static $_db_pointer = NULL; private function __construct() { $this->_db_pointer = mysql_connect(DB_HOST, DB_USER, DB_PASS); mysql_select_db(DB_DATABASE); } public static function get_connection() { if(self::$_db_pointer == NULL) { return new self(); } else { echo "Error:only one connection"; } } } /*database*/ abstract class database { protected function __construct() { single_connect::get_connection(); } static protected function query($query) { $result = mysql_query($query) or die(mysql_error()); return $result; } } /*table*/ class table extends database { public $_protected_arr=array(); protected function __construct() { parent::__construct(); self::protect(); } protected function protect() { foreach($_POST as $key => $value) { $this->_protected_arr[$key] = mysql_real_escape_string($value); } } } /*bookmark*/ class bookmark extends table { function __construct() { parent::__construct(); $this->start(); } function start() { if(self::test()) { self::insert(); } else { return 1; } } function test() { if(self::test_empty()) { return 1; } else { return 0; } } function test_empty() { if(text::test_empty($this->_protected_arr)) { return 1; } else { return 0; } } function insert() { $url = $this->_protected_arr['url']; $title = $this->_protected_arr['title']; $email = $_SESSION['email']; database::query("INSERT INTO bo VALUES ('$title', '$url', '$email')"); } }

[objective c] formatting negative currency amount
I have trouble formatting negative amounts. I have defined the following formatter : NSNumberFormatter *nf = [[NSNumberFormatter alloc] init]; [nf setNumberStyle:NSNumberFormatterCurrencyStyle]; [nf setNegativeFormat:@"-¤#,##0.00"]; In an environment using an en_US locale, parsing the string @"-$244.32" returns a correct NSNumber object. However, parsing the string @"-€244.32" with a fr_FR locale returns nil. Do you have any ideas ? Thanks

Animated GIF in IE 8 stopping
I need to diplay a spin gif. I was following this link http://stackoverflow.com/questions/780560/animated-gif-in-ie-stopping and the solution given to break up your GIF to say 10 images. I tried that however its not giving me the right results either on IE8 or Chrome17. Only half of the frames gets displayed on both IE8 and chrome. However when i right click on spinner image on IE8 it starts showing the image correctly till the time rightclick pop up is open on the image. Any help on this issue would be appreciated. Thanks.

Product page says "out of stock" even though SKU at 50
I've created a catalog with about 10 products and I've made sure each of them have a SKU of at least 50. Yet, when I go to an individual product's page, it tells me that the product is out of stock - which makes no sense whatsoever to me. Anyone know what might be causing this?

How does a typical HTTP connection redirect to VPN tunnel?
For l2tp tunneling, it uses PPPoX. However, a typical HTTP connection will create with AF_INET. So, how the connection will be redirected to the PPPoX? I suspect two points: 1. in socket_create 2. ip forwarding But, after looking at data path and source code, I don't think my guess is right. Anybody has some idea?

PDF Cross Reference Streams
I'm developing a PDF parser/writer, but I'm stuck at generating cross reference streams. My program reads [this][1] file and then removes its linearization, and decompresses all objects in object streams. Finally it builds the PDF file and saves it. This works really well when I use the normal cross reference & trailer, as you can see in [this][2] file. When I try to generate a cross reference stream object instead (which results in [this][3] file, Adobe Reader can't view it. Has anyone experience with PDF's and can help me search what the Problem is? Note that the cross reference is the ONLY difference between file 2 and file 3. The first 34127 bytes are the same. If someone needs the content of the decoded reference stream, download [this][4] file and open it in a HEX editor. I've checked this reference table again and again but I could not find anything wrong. But the dictionary seems to be OK, too. Thanks so much for your help!!!

Non Deterministic Push-Down Automata Simulation
Develop an application system to simulate a Non-Deterministic Push-Down Automata(NPDA). 1) Input to your NPDA is a set of s-grammar rules of the form A => aX where X  N * recorded in a text file named productions.txt. 2) Number of rules in the rule set should be at least five. 3) The left Non-terminal of the first rule in your set of productions is assumed to be the start symbol of the grammar. 4) All terminals are assumed to be single lower case characters from the range a..z. 5) All non-terminals are assumed to be single upper case characters from the range A..Z. Your NPDA should be able to accept any string of characters from the alphabet A…Za..z and to respond to the give string as below. 1) Print the word Reject if the string is not in the language. 2) Print the word Accept followed by the derivation steps if the string is in the language. any one can give better NPDA for this question(set of grammar rules )

Virtualbox USB driver problem for Windows Mobile 6.5 HD2
I try to connect my Windows Mobile Device (Hd2) with VirtalBox using MacOS as the host (10.6.5) and Windows 7 as the guest. The device shows up as HTC Generic Serial and Windows tries to install it as "PocketPC USB Sync" and fails to install the driver. According to forums with people that have similar problems you should turn off "advanced network functionality" (I think I did this.. have swedish menus) and blacklist drivers in linux (no idea how to do). Anyone has any good ideas? Will it be easier if I run Windows as a host? /Br Johannes

working of fork in c language

I write a code which is following : code :`#include<stdio.h> int main() { int a, b; b=fork(); printf("\nmy name is manish\n"); printf("\n my name is anil\n"); printf("\n the value of b = %d",b); }` The output of this code is following : **my name is manish my name is anil my name is manish my name is anil the value of b = 2244 the value of b = 0manish.yadav@ws40-man-lin:~$** Now I don't understand why the output is like this ? After that i just add a line to my code and output is completely different. my code is following: code:`int main() { int a, b; b=fork(); printf("\nmy name is manish\n"); printf("\n my name is anil\n"); printf("\nmy name is sunil\n"); printf("\n the value of b = %d",b); }' when i run the code the output is following **my name is manish my name is anil my name is sunil the value of b = 2389my name is manish my name is anil my name is sunil the value of b = 0** Now I'm totally confused about the working of fork() call. my question are following: 1. How fork works ? 2. Where the control goes after the fork call? 3. Can any body explain why the outputs of codes written in problem ? 4. why the out put of b occurring at different places means in first code the output of b =2260 is just before the output b=o while the value of b=2389 is not just before the b=0 ? Please explain me the working of fork in the code written in the problem so that I can learn it properly .

How to shift development of an existing MVC3 app to a TDD approach?
I have a fairly large MVC3 application, of which I have developed a small first phase without unit testing. I know it's a bit irresponsible to say this, but it hasn't really been necessary so far, with very simple CRUD operations, but I would like to move toward a TDD approach going forward. I have basically completed phase 1, where members can register as authors and create course modules. Now I have more complex phases to implement where consumers of the courses and their trainees must register and complete courses, with academic progress tracking, author feedback and financial implications. I feel it would be unwise to proceed without a solid unit testing strategy, and based on past experience I feel TDD would be quite suitable here. Are there any known procedures for 'converting' a development effort to TDD, and for introducing unit tests to already written code? I don't need kindergarten level step by step stuff, but general strategic guidance. *BTW, I have included the web-development and MVC tags on this question as I believe these fields of development can significant influence on the unit testing requirements of project artefacts. If you disagree and wish to remove any of them, please be so kind as to leave a comment saying why.*

ASP.NET MVC 2 Drop Down List In Place of Master List Grid
Instead of a grid with an 'Edit' link in each row, I'd like to use a drop down list and a single 'Edit' button. What's the cleanest way to make that button direct to /Edit/{id}(i.e. the ddl selected value)? Using onclick with window.location is way too ugly, super ugly if I have to account for the url base being http://approot/ or http://approot/controllername/ since it's on the Index view.

So I have a for-loop which returns for each result record a id Name StartDate EndDate here it is the for-loop below > for (var i = 0; i < data.d.results.length; i++) { } So at the end depending on how many records returned I am going to have a few of these. What I do want to do is as these records are created dynamically in the loop add them to a json object of mine jsonObject= [{ id: 0, name: Name1, series: [{ start: Startdate1, end: Enddate1 }], id: 1, name: Name2, series: [{ start: Startdate2, end: Enddate2 }], id: 2, name: Name3, series: [{ start: Startdate3, end: Enddate3 }], }]; So through the loop the id's 1 get added within the object, then 2 then 3. I've been reading up on the .push method but not sure how I structure this one.
