  • Getting your bearings and defining the project objective

    - by johndoucette
    I wrote this two years ago and thought it was worth posting… Some may think this is a daunting task and some may even say “what a waste of time” and want to open MS Project and start typing out tasks because someone asked for an estimate and a task list. Hell, maybe you even use Excel and pump out a spreadsheet with some real scientific formula for guessing how long it will take to code a bunch of classes. However, this short exercise will provide the basis for the entire project, whether small or large and be a great friend when communicating to anyone on your team or even your client. I call this the Project Brief. If you find yourself going beyond a single page, then you must decompose the sections and summarize your findings so there is a complete and clear picture of the project you are working on in a relatively short statement. Here is a great quote from the PMBOK (Project Management Body of Knowledge) relative to what a project is;   A project is a temporary endeavor undertaken to create a unique product, service or result. With this in mind, the project brief should encompass the entirety (objective) of the endeavor in its explanation and what it will take (goals) to create the product, service or result (deliverables). Normally the process of identifying the project objective is done during the first stage of a project called the Project Kickoff, but you can perform this very important step anytime to help you get a bearing. There are many more parts to helping a project stay on course, but this is usually the foundation where it can be grounded on. Through a series of 3 exercises, you should be able to come up with the objective, goals and deliverables on your project. Follow these steps, and in no time (about &frac12; hour), you will have the foundation of your project plan. (See examples below) Exercise 1 – Objectives Begin with the end in mind. Think about your project in business terms with a couple things to help you understand the objective; Reference the business benefit in terms of cost, speed and / or quality, Provide a higher level of what the outcome will look like (future sense) It should be non-measurable, that’s what the goals are all about The output should be a single paragraph with three sentences and take 10 minutes to write. *Typically, agreement must be reached on the objectives of the project before you would proceed to the next steps of the project. Exercise 2 – Goals A project goal is a statement that answers questions about who, what, why, where and when. A good project goal statement; Answers the five “W” questions for the project Is measurable in each of its parts Is published and agreed on by all the owners This helps the Project Manager receive confirmation on defining the project target. Using the established project objective done in the first exercise, think about the things it will take to get the job done. Think about tangible activities which are the top level tasks in a typical Work Breakdown Structure (WBS). The overall goal statement plus all the deliverables (next exercise) can be seen as the project team’s contract with the project owners. Write 3 - 5 goals in about 10 minutes. You should not write the words “Who, what, why, where and when, but merely be able to answer the questions when you read a goal. Exercise 3 – Deliverables Every project creates some type of output and these outputs are called deliverables. There are two classes of deliverables; Internal – produced for project team members to meet their goals External – produced for project owners to meet their expectations The list you enter here provides a checklist for the team’s delivery and/or is a statement of all the expectations of the project owners. Here are some typical project deliverables; Product and product documentation End product/system Requirements/feature documents Installation guides Demo/prototype System design documents User guides/help files Plans Project plan Training plan Conversion/installation/delivery plan Test plans Documentation plan Communication plan Reports and general documentation Progress reports System acceptance tests Outstanding bug list Procedures Risk and issue logs Project history Deliverables should go with each of the goals. Have 3-5 deliverables for each goal. When you are done, you will have established a great foundation for the clarity of your project. This exercise can take some time, but with practice, you should be able to whip this one out in 10 minutes as well, especially if you are intimate with an ongoing project. Samples  Objective [Client] is implementing a series of MOSS sites to support external public (Internet), internal employee (Intranet) and an external secure (password protected Internet) applications. This project will focus on the public-facing web site and will provide [Client] with architectural recommendations based on the current design being done by their design partner [Partner] and the internal Content Team. In addition, it will provide [Client] with a development plan and confidence they need to deploy a world class public Internet website. Goals 1.  [Consultant] will provide technical guidance and set project team expectations for the implementation of the MOSS Internet site based on provided features/functions within three weeks. 2.  [Consultant] will understand phase 2 secure password-protected Internet site design and provide recommendations.   Deliverables 1.1  Public Internet (unsecure) Architectural Recommendation Plan 1.2  Physical Site construction Work Breakdown Structure and plan (Time, cost and resources needed) 2.1  Two Factor authentication recommendation document   Objective [Client] is currently using an application developed by [Consultant] many years ago called "XXX". This application, although functional, does not meet their new updated business requirements and contains a few defects which [Client] has developed work-around processes. [Client] would like to have a "new and improved" system to support their membership management needs by expanding membership and subscription capabilities, provide accounting integration with internal (GL) and external (VeriSign) systems, and implement hooks to the current CRM solution. This effort will take place through a series of phases, beginning with envisioning. Goals 1. Through discussions with users, [Consultant] will discover current issues/bugs which need to be resolved which must meet the current functionality requirements within three weeks. 2. [Consultant] will gather requirements from the users about what is "needed" vs. "what they have" for enhancements and provide a high level document supporting their needs. 3. [Consultant] will meet with the team members through a series of meetings and help define the overall project plan to deliver a new and improved solution.

  • How do I call up values in PHP for user input in forms (radio buttons and selects)

    - by Derek
    Ok so my admin sets to edit a book which was created. I know how to bring in the values that were initially entered via a simple text field like 'bookname'. On the edit book page the book name field stores the currently assigned 'bookname' in the field (which is what I want! :) ) However I have other field types like selects and radio button entries...I'm having trouble calling in the already set value when the book was created. For example, there is a 'booklevel' field, which I have set as radio button entries as; Hard, Normal, and Easy. When the user goes to edit the book, I'm not too sure on how to have the current value drawn up (its stored as text) and the radio button being checked. I.e. 'Normal' is checked if this is what was set when the book was created. So far I have this as the code for the adding book level: <label>Book Level:</label> <label for="booklevel1" class="radio">Hard <input type="radio" name="booklevel" id="booklevel1" value="<?php echo 'Hard'; if (isset($_POST['booklevel'])); ?>"></label> <label for="booklevel2" class="radio">Medium<input type="radio" name="booklevel" id="booklevel2" value="<?php echo 'Normal'; if (isset($_POST['booklevel'])); ?>"></label> <label for="booklevel" class="radio">Low<input type="radio" name="booklevel" id="booklevel3" value="<?php echo 'Easy'; if (isset($_POST['booklevel'])); ?>"></label> This all works fine by the way when the user adds the book... But does anyone know how in my update book form, I can draw the value of what level has been set, and have the box checked?? To draw up the values in the text fields, I'm simply using: <?php echo $row['bookname']?> I also noticed a small issue when I call up the values for my Select options. I have the drop down select field display the currently set user (to read the book!), however, the drop down menu again displays the user in the list available options to select - basically meaning 2 of the same names appear in the list! Is there a way to eliminate the value of the SELECTED option? So far my setup for this is like: <select name="user_id" id="user_id"> <option value="<?php echo $row['user_id']?>" SELECTED><?php echo $row['fullname']?></option> <?php while($row = mysql_fetch_array($result)) { ?> <option value="<?php echo $row['user_id']?>"><?php echo $row['name']?></option> <?php } ?> </select> If anyone can help me I'll be very greatful. Sorry for the incredibly long question!! :)

  • Linked list in C

    - by ScReYm0
    I am still new at lists in C and i got a big problem... First i wanna show you my code for inserting item to the list: void input_books_info(int number_of_books, BOOK *current) { int i; for(i = 0; i < number_of_books; i++) { while(current->next != NULL) current = current->next; current->next = (BOOK *)malloc(sizeof(BOOK)); printf_s("%d book catalog number: ", i + 1); scanf_s("%s", &current->next->catalog_number , 20); printf_s("%d book title: ", i + 1); scanf_s("%s", current->next->title ,80); printf_s("%d book author: ", i + 1); scanf_s("%s", current->next->author ,40); printf_s("%d book publisher: ", i+1); scanf_s("%s", current->next->publisher,80); printf_s("%d book price: ", i + 1); scanf_s("%f", &current->next->price, 5); printf_s("%d book year published: ", i + 1); scanf_s("%d", &current->next->year_published, 5); current->next->next = NULL; printf_s("\n\n"); } } And this is my main function: void main (void) { int number_of_books, t = 1; char book_catalog_number[STRMAX]; char book_title[STRMAX]; char book_author[STRMAX]; char reading_file[STRMAX]; char saving_file[STRMAX]; first = malloc(sizeof(BOOK)); first->next = NULL; /* printf_s("Enter file name: "); gets(saving_file); first->next = book_open(first, saving_file); */ while(t) { char m; printf_s("1. Input \n0. Exit \n\n"); printf_s("Choose operation: "); m = getch(); switch(m) { case '1': printf_s("\ninput number of books: "); scanf_s("%d", &number_of_books); input_books_info(number_of_books, first); printf_s("\n"); break; default: printf_s("\nNo entry found!\n\n\n\n\n"); break; } } } and last maybe here is the problem the printing function: void print_books_info(BOOK *current) { while(current->next != NULL && current != NULL) { printf_s("%s, ", current->next->catalog_number); printf_s("%s, ", current->author); printf_s("%s, ", current->next->title); printf_s("%s, ", current->next->author); printf_s("%s, ", current->next->publisher); printf_s("%.2f, ", current->next->price); printf_s("%d", current->next->year_published); printf_s("\n\n"); current = current->next; } } And my problem is that, when i run the app, program is moving good. But when I start the app, the program is storing only first input of data second and third are lost ... Can you help me to figure out it... ???

  • Converting a WPFToolkit DataGrid from 1D list to 2D matrix

    - by user61073
    Hello - I am wondering if anyone has attempted the following or has an idea as to how to do it. I have a WPFToolkit DataGrid which is bound to an ObservableCollection of items. As such, the DataGrid is shown with as many rows in the ObservableCollection, and as many columns as I have defined in for the DataGrid. That all is good. What I now need is to provide another view of the same data, only, instead, the DataGrid is shown with as many cells in the ObservableCollection. So let's say, my ObservableCollection has 100 items in it. The original scenario showed the DataGrid with 100 rows and 1 column. In the modified scenario, I need to show it with 10 rows and 10 columns, where each cell shows the value that was in the original representation. In other words, I need to transform my 1D ObservableCollection to a 2D ObservableCollection and display it in the DataGrid. I know how to do that programmatically in the code behind, but can it be done in XAML? Let me simplify the problem a little, in case anybody can have a crack at this. The XAML below does the following: * Defines an XmlDataProvider just for dummy data * Creates a DataGrid with 10 columns o each column is a DataGridTemplateColumn using the same CellTemplate * The CellTemplate is a simple TextBlock bound to an XML element If you run the XAML below, you will find that the DataGrid ends up with 5 rows, one for each book, and 10 columns that have identical content (all showing the book titles). However, what I am trying to accomplish, albeit with a different data set, is that in this case, I would end up with one row, with each book title appearing in a single cell in row 1, occupying cells 0-4, and nothing in cells 5-9. Then, if I added more data and had 12 books in my XML data source, I would get row 1 completely filled (cells covering the first 10 titles) and row 2 would get the first 2 cells filled. Can my scenario be accomplished primarily in XAML, or should I resign myself to working in the code behind? Any guidance would greatly be appreciated.

  • Infrared usb adapter not hot pluggable?

    - by A. Goossens
    For transferring exercise files from my Polar heart rate monitor i use the software Protrainer 5 with an external infrared usb adapter. Using Wine to run Protrainer 5 and some adjustments mentioned here (using irda-utils) i managed to make it work. Well, sort of: every time i want to transfer exercise files and the adapter is not plugged in i have to reboot my laptop with the usb adapter plugged in to make it work. Since i have a laptop it unfortunately is no option to just always leave the adapter in. It seems to me that the usb adapter isn't hot pluggable (which seems odd for a usb device) or there must be another problem. Polar WebLink (other software to transfer exercise files) experiences the same issue. Can anyone help me to fix this problem?

  • Perl, LibXML and Schemas

    - by Xetius
    I have an example Perl script which I am trying to load and validate a file against a schema, them interrogate various nodes. #!/usr/bin/env perl use strict; use warnings; use XML::LibXML; my $filename = 'source.xml'; my $xml_schema = XML::LibXML::Schema->new(location=>'library.xsd'); my $parser = XML::LibXML->new (); my $doc = $parser->parse_file ($filename); eval { $xml_schema->validate ($doc); }; if ($@) { print "File failed validation: $@" if $@; } eval { print "Here\n"; foreach my $book ($doc->findnodes('/library/book')) { my $title = $book->findnodes('./title'); print $title->to_literal(), "\n"; } }; if ($@) { print "Problem parsing data : $@\n"; } Unfortunately, although it is validating the XML file fine, it is not finding any $book items and therefore not printing out anything. If I remove the schema from the XML file and the validation from the PL file then it works fine. I am using the default namespace. If I change it to not use the default namespace (xmlns:lib="http://libs.domain.com" and prefix all items in the XML file with lib and change the XPath expressions to include the namespace prefix (/lib:library/lib:book) then it again works file.

  • java enterprise project

    - by darko petreski
    Hi All, All the time we are hearing that java is enterprise. We have read many books about jpa, entity beans and other stuff. All this books explain this technology with some dummy examples. I have not seen a book that explains real problems with enterprise beans, java clients and security! I mean real book not some imaginated stupid examples . Is there any book that describes completely some enterprise system, Its architecture, communication, security, of course the client that uses the distributed components ? I need a book that will cover the flowing: server side components (ejb, jpa) client side java desktop application security (authentication and authorization) web services with complete authentication clustering (we can find for all of this a book, but there is no book that covers all this things in one piece. Also all the books are with dummy samples.) Or may be some project that is documented. Regards, Darko

Book book =new Book("LOTR"); var userBook=user.AddBook(book); After session flushing OnPreInsert event called once for newly created Book object than OnPreUpdate called for all books objects in user's books collection even they have not changed.So I am updating LastMofiedDate property of all books objects and I dont want to do this. Is this supposed behaviour of NHibernate or am I missing something?

  • using Java interfaces

    - by mike_hornbeck
    I need to create interface MultiLingual, that allows to display object's data in different languages (not data itself, but introduction like "Author", "Title" etc.). Printed data looks like this : 3 grudnia 1998 10th of June 1924 Autor: Tolkien Tytul: LoTR Wydawnictwo: Amazon 2010 Author: Mitch Albom Title: Tuesdays with Morrie Publishing House: Time Warner Books 2003 37 360,45 PLN 5,850.70 GBP 3rd of December 1998 10th of June 1924 Author: Tolkien Title: LoTR Publishing House: Amazon 2010 Author: Mitch Albom Title: Tuesdays with Morrie Publishing House: Time Warner Books 2003 37,360.45 GBP 5,850.70 GBP Test code looks like this : public class Main { public static void main(String[] args){ MultiLingual gatecrasher[]={ new Data(3,12,1998), new Data(10,6,1924,MultiLingual.ENG), new Book("LoTR", "Tolkien", "Amazon", 2010), new Book("Tuesdays with Morrie", "Mitch Albom", "Time Warner Books",2003, MultiLingual.ENG), new Money(1232895/33.0,MultiLingual.PL), new Money(134566/23.0,MultiLingual.ENG), }; for(int i=0;i < gatecrasher.length;i++) System.out.println(gatecrasher[i]+"\n"); for(int i=0;i < gatecrasher.length;i++) System.out.println(gatecrasher[i].get(MultiLingual.ENG)+"\n"); } } So i need to introduce constants ENG, PL in MultiLingual interface, as well as method get(int language) : public interface MultiLingual { int ENG = 0; int PL= 1; String get(int lang); } And then I have class Book. Problem starts with the constructors. One of them needs to take MultiLingual.ENG as argument, but how to achieve that ? Is this the proper way? : class Book implements MultiLingual { private String title; private String publisher; private String author; public Book(String t, String a, String p, int y, MultiLingual lang){ } Or should I treat this MultiLingual.ENG as int variable , that will just change automatically constants in interface? Second constructor for book doesn't take MultLingual as argument, but following implementation is somehow wrong : public Book(String t, String a, String p, int y){ Book someBook = new Book(t, a, p, y, MultiLingual m); } I could just send int m in place of MultiLingual m but then I will have no control if language is set to PL or ENG. And finally get() method for Boook but I think at least this should be working fine: public String get(int lang){ String data; if (lang == ENG){ data = "Author: "+this.author+"\n"+ "Title: "+this.title+"\n"+ "Publisher: "+this.publisher+"\n"; } else { data = "Autor: "+this.author+"\n"+ "Tytul: "+this.title+"\n"+ "Wydawca: "+this.publisher+"\n"; } return data; } @Override public String toString(){ return ""; } }

  • Fill a list from JSP in Spring

    - by Javi
    Hello, I have something like this in my Spring Application: public class Book{ public Book(){ sheets = new LinkedList<Sheet>(); } protected List<Sheet> sheets; //getter and setter } I add several Sheets to the sheet list and I print a form in a JSP like this: <form:form modelAttribute="book" action="${dest_url}" method="POST"> <c:forEach items="${mybook.sheets}" var="sheet" varStatus="status"> <form:hidden path="sheet[${status.count -1}].header"/> <form:hidden path="sheet[${status.count -1}].footer"/> <form:hidden path="sheet[${status.count -1}].operador"/> <form:hidden path="sheet[${status.count -1}].number"/> <form:hidden path="sheet[${status.count -1}].lines"/> </c:forEach> ... </form:form> I need to get back this list in the controller when the form is submitted. So in my controller I have a method with a parameter like this: public String myMethod (@ModelAttribute("book") Book book, Model model){ ... } The problem is that it doesn't fill the sheets list unless in the constructor of Book I add as much Sheet's as I want to get. The problem is that I don't know in advance the number of Sheets the book is going to have. I think the problem is that in my method it instantiates Book which has a list of sheets with 0 elements. When it tries to access to sheets[0] the list is empty and it doen't add a Sheet. I've tried to create a getter method for the list with an index parameter (so it can create the element if it doesn't exists in the list like in Struts framework) like this one: public Sheet getSheets(int index){ if(sheets.size() <= index){ Sheet sheet = new Sheet(); sheets.add(index, sheet); } Sheet sheetToReturn = sheets.get(index); if(sheetToReturn == null){ sheetToReturn = new Sheet(); sheets.add(index, sheetToReturn); } return sheetToReturn; } but with this method the JSP doesn't work because sheets has an invalid getter. What's the proper way of filling a list when you don't know the number of items in advanced? Thanks

  • next line character a huge influence on xmlparser?

    - by jovany
    I have question about a basic xml file I'm parsing and just putting in simple nextlines(Enters). I'll try to explain my problem with this next example. I'm( still) building an xml tree and all it has to do ( this is a testtree ) is put the summary in an itemlist. I then export it to a plist so I can see if everything is done correctly. A method that does this is in the parser which looks like this if([elementName isEqualToString:@"Book"]) { [appDelegate.books addObject:aBook]; [aBook release]; aBook = nil; } else { [aBook setValue:currentElementValue forKey:elementName]; NSString *directions = [NSString stringWithFormat:currentElementValue]; [directionTree = setObject:directions forKey:@"directions"]; } [currentElementValue release]; currentElementValue = nil; } the export for the plistfile happens at the endtag of books. Below is the first xmlfile <?xml version="1.0" encoding="UTF-8"?> <Books><Book id="1"><summary>Ero adn the ancient quest to measure the globe.</summary></Book><Book id="2"><summary>how the scientific revolution began.</summary></Book></Books> This is my output http://img139.imageshack.us/img139/9175/picture6rtn.png If I make some adjustments like here <?xml version="1.0" encoding="UTF-8"?> <Books><Book id="1"> <summary>Ero adn the ancient quest to measure the globe.</summary> </Book> <Book id="2"> <summary>how the scientific revolution began.</summary> </Book> </Books> My directions key with type string remains empty... http://img248.imageshack.us/img248/5838/picture7y.png I never knew that if I just put in an enter it would have such an influence. Does anyone know a solution to this since my real xml file looks like this. ps. the funny thing is I can actually see ( when debugging)my directions string (NSString directions ) fill up with the currentElementValue in both cases.

  • What are "web services"?

    - by Kevin
    I'm reading a book about programming ASP.NET in C#. The book makes the following comment: Previous editions of this book tackled web services, a feature that allows you to create code routines that can be called by other applications over the Internet.Web services are more interesting when considering rich client development (because they allow you to give web features to ordinary desktop applications),and they’re in the process of being replaced by a new technology known as WCF (Windows Communication Foundation). For those reasons, web services aren’t covered in this book.However,if you want to branch out and explore the web service world,you can download the web service chapters from the previous edition of this book from the book’s download page.The information in these chapters still applies to ASP.NET 3.5,because the web service feature hasn’t changed. Can someone offer, in "layman's terms" what exactly a web service is and if, indeed, they are being replaced, at least in .Net, with WCF? What would be a practical example of a web service? Are they stand alone programs that run on a web server and are invoked by a client or clients?

  • Is there a way to enforce/preserve order of XML elements in an XML Schema?

    - by MarcoS
    Let's consider the following XML Schema: <?xml version="1.0" encoding="UTF-8"?> <schema targetNamespace="http://www.example.org/library" elementFormDefault="qualified" xmlns="http://www.w3.org/2001/XMLSchema" xmlns:lib="http://www.example.org/library"> <element name="library" type="lib:libraryType"></element> <complexType name="libraryType"> <sequence> <element name="books" type="lib:booksType"></element> </sequence> </complexType> <complexType name="booksType"> <sequence> <element name="book" type="lib:bookType" maxOccurs="unbounded" minOccurs="1"></element> </sequence> </complexType> <complexType name="bookType"> <attribute name="title" type="string"></attribute> </complexType> </schema> and a corresponding XML example: <?xml version="1.0" encoding="UTF-8"?> <lib:library xmlns:lib="http://www.example.org/library" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.example.org/library src/library.xsd "> <lib:books> <lib:book title="t1"/> <lib:book title="t2"/> <lib:book title="t3"/> </lib:books> </lib:library> Is there a way to guarantee that the order of <lib:book .../> elements is preserved? I want to be sure that any parser reading the XML will return books in the specified oder, that is first the book with title="t1", then the book with title="t2", and finally the book with title="t3". As far as I know XML parsers are not required to preserve order. I wonder whether one can enforce this through XML Schema? One quick solution for me would be adding an index attribute to the <lib:book .../> element, and delegate order preservation to the application reading the XML. Comments? Suggestions?

  • Resetting a partial using RJS, and passing an instance variable?

    Hey guys here is my code (roughly): books.html.erb <% @books.each do |book| %> <% @bookid = book.id %> <div id="enter_stuff"> <%= render "input", :bookid => @bookid %> </div> <%end%> _input.html.erb <% @book = Book.find_by_id(@bookid) %> <strong>your book is: <%=h @book.name %></strong> create.rjs page.replace_html :enter_stuff, :partial => 'input2', :object => @bookid Only create.js doesn't seem to work though, if instead of passing the partial I passed "..." it does work, so I know its that there are instance variables in the partial that aren't being reset. Any ideas?

  • A btter way to represent Same value given multiple values(C#3.0)

    - by Newbie
    I have a situation for which I am looking for a more elegant solution. Consider the below cases "BKP","bkp","book-to-price" (will represent) BOOK-TO-PRICE "aop","aspect oriented program" (will represent) ASPECT-ORIENTED-PROGRAM i.e. if the user enter BKP or bkp or book-to-price , the program should treat that as BOOK-TO-PRICE. The same holds good for the second example(ASPECT-ORIENTED-PROGRAM). I have the below solution: Solution: if (str == "BKP" || str == "bkp" || str == "book-to-price" ) return "BOOK-TO-PRICE". But I think that there can be many other better solutions . Could you people please give some suggestion.(with an example will be better) I am using C#3.0 and dotnet framework 3.5

  • How to access a subset of XML data in Java when the XML data is too large to fit in memory?

    - by Michael Jones
    What I would really like is a streaming API that works sort of like StAX, and sort of like DOM/JDom. It would be streaming in the sense that it would be very lazy and not read things in until needed. It would also be streaming in the sense that it would read everything forwards (but not backwards). Here's what code that used such an API would look like. URL url = ... XMLStream xml = XXXFactory(url.inputStream()) ; // process each <book> element in this document. // the <book> element may have subnodes. // You get a DOM/JDOM like tree rooted at the next <book>. while (xml.hasContent()) { XMLElement book = xml.getNextElement("book"); processBook(book); } Does anything like this exist?

  • Initial review of Developer's Guide to Collections in Microsoft® .NET

    - by TATWORTH
    The code is well illustrated by diagrams. The approach is practical. The code is well commented, however the C# code samples would be better had they been fully Style Cop compliant. I am looking forward to reviewing the rest of this excellent book. I recommend this book to all C# and VB.NET Development teams. I concur with the author who states that the book is not for learning C# or VB.NET. It is an excellent book for C# or VB.NET developers to extend their knowledge of the Dot Net framework.
