  • How can a non-technical person can learn to write a spec for small projects?

    - by Joseph Turian
    How can a non-technical person learn to write specs for small projects? A friend of mine is trying to outsource some development on a statistics project. In particular, he does a lot of work in excel, and wants to outsource the creation of scripts to do what he now does by hand. However, my friend is extremely non-technical. He is poor at writing technical specs. When he does write a spec, it is written the way you would describe doing something in excel (go to this cell and then copy the value to that cell). It is also overly verbose, and does examples several times. I'm not sure if he properly describes corner cases. The first project he outsourced was a failure. I think he overdescribed some details, but underdescribed corner cases. That and/or the coder he hired didn't think through the corner cases and ask appropriate questions. I'm not sure. I got on IM with him and it took me half an hour to dig out a description that should have taken five minutes or less to describe. I wrote the scripts for him at the end, but didn't examine why his process with the coder failed. He has asked me for help. However, I refuse to get involved, because taking his spec and translating it into clear requirements is 10x more work than executing on a clearly written spec. What is the right way for him to learn? Are there resources he could use? Are there ways he can learn from small, low-pressure practice projects with coders? [edit: Most of his scripts are statistical and data processing oriented. e.g. take this column and run an average over it. Remove these rows under these conditions. So the challenge is different than spec'ing a web app.]

  • Junior developer introduction to job industry

    - by lady_killer
    I am a junior developer at my second working experience, the first one using PHP with WordPress and currently on Groovy on Grails. I like coding, I attend meetup to discuss technology etc but I still did not understand how to become a real professional with the "know how" attitude. I read Clean Coder, the author advises to spend 20 hours per week of my spare time to learn new technologies and to keep myself up to date. I do not find this realistic, if you want to have a bit of a social life, and I also noticed that learning at work, at least in the places where I worked, is not ideal. No support from seniors for new projects, no pair programming and code reviews, no company trainings, one hour a week tech meetings where seniors walk away after a bit because they already know the topic discussed and so on. Sometimes is quite hard to keep the motivation... My questions are: Is our industry supposed to be like this? Is there real team working in the sense of sharing knowledge and help juniors to get up to speed? Are we supposed to learn new technologies or technology features just in our spare time?Clean Coder says football players do not train during official matches and our working hours are like official matches, we should just perform and learn in other moments. Is it really like this? How can I improve my skills with no support? Is it enough to read books and try out the exercises and perhaps some katas? In almost 5 month of Groovy on Grails experience at work, I have never had the opportunity to create anything from scratch, just worked on existing issues where it was even really difficult to get the domain knowledge from senior devs.

  • BadImageFormatException when loading 32 bit DLL, target is x86

    - by Coder
    I have a DLL (FreeType) which is certainly 32-bit (header: IMAGE_FILE_MACHINE_I386). I want to use it from C# code, using DllImport. Target of my application is x86, IntPtr.Size is 4, process is 32-bit. But I get BadImageFormatException (Exception from HRESULT: 0x8007000B). What can be wrong? Of course I use 64-bit Windows 7.

  • JavaScript keeps returning ambigious error (in ASP.NET MVC 2.0)

    - by Erx_VB.NExT.Coder
    this is my function (with other lines ive tried/abandoned)... function DoClicked(eNumber) { //obj.style = 'bgcolor: maroon'; var eid = 'cat' + eNumber; //$get(obj).style.backgroundColor = 'maroon'; //var nObj = $get(obj); var nObj = document.getElementById(eid) //alert(nObj.getAttribute("style")); nObj.style.backgroundColor = 'Maroon'; alert(nObj.style.backgroundColor); //nObj.setAttribute("style", "backgroundcolor: Maroon"); }; This error keeps getting returned even after the last line in the function runs: Microsoft JScript runtime error: Sys.ArgumentUndefinedException: Value cannot be undefined. Parameter name: method this function is called with an "OnSuccess" set in my Ajax.ActionLink call (ASP.NET MVC)... anyone any ideas on this? i have these referenced... even when i remove the 'debug' versions for normal versions, i still get an error but the error just has much less information and says 'b' is undefined (probably a ms js library internal variable)... <script src="../../Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script> <script src="../../Scripts/MicrosoftMvcValidation.debug.js" type="text/javascript"></script> <script src="../../Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script> <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script> also, this is how i am calling the actionlink method: Ajax.ActionLink(item.CategoryName, "SubCategoryList", "Home", New With {.CategoryID = item.CategoryID}, New AjaxOptions With {.UpdateTargetId = "SubCat", .HttpMethod = "Post", .OnSuccess = "DoClicked(" & item.CategoryID.ToString & ")"}, New With {.id = "cat" & item.CategoryID.ToString})

  • Why not to use Array of errors instead of Exception Handling !?

    - by Naughty.Coder
    Why not using array of errors instead of throwing errors and check if it's not empty later in the code.... Exception handling is very confusing to me , I can not understand it's purpose ... can anybody enlighten me !? they compare it with die() as better not to stop the execution of the code , why would I stop the execution of code if I don't want to !? ofcourse I do I'm a beginner programmer , it might be confusing to you as well , or because i'm not very experienced in this ugly thing. Please in the context of PHP only.

  • How do i translate movement on the Canvas3D to movement in the virtual 3D world

    - by Coder
    My goal is to move a shape in the virtual world in such a way so that it ends up where the mouse pointer is on the canvas. What i have: -mouse position (x,y) on a Canvas3D object -Point3d object of where a pick ray starting from the Canvas3D viewport intersects with the first scene object. (point in 3D space of where i want to start the drag) What i want: -Some way to translate the Point3d's coordinates so that the initial point of intersection (the Point3d object) is always overlapping the the mouse position on the canvas (same as when i used the pick ray to determine what the user clicked on from the Canvas3D object). Thanks!

  • What's PHP Equivalent of Java Servlet Filter?

    - by ZZ Coder
    On Java side, we have a servlet filter that handles authentication. We don't have to change all other servlet or JSPs to add authentication to the page, unless the page needs customized content. How can we achieve the same on PHP? We don't use any frameworks on PHP.

  • ASP.NET MVC 2.0 Unused Model Property being called when posting a product to the server?

    - by Erx_VB.NExT.Coder
    i have my auto-generated linq to sql classes, and i extend this class using partial classing (instead of using inheritance), and i have properties that that i've put in later which are not part of the database model and should not be. these are things like "FinalPrice" and "DisplayFinalPrice" - in the dbase, there is only RetailPrice and WholesalePrice so FinalPrice etc are more like extensions of the dbase fields. when i submit the form with nothing filled in, "FinalPrice" gets called (the 'get' of the property) even tho i never ask for it to be, and even tho it is not needed. this happens before validation, so i don't even get the validation errors i would get. i've tried using and on the FinalPrice and FinalPriceDisplay properties - no go! why does this happen and how can i stop it from happening? is the modelstate just trying to validate everything so therefore it calls every item no matter what? for those interested, here is all the code... Partial Public Class tProduct 'Inherits tProduct Private Const CommissionMultiplier As Decimal = CDec(1.18) Private _FinalPrice As Decimal? Private _DisplayFinalPrice As String Private _DisplayNormalPrice As String Public Property CategoryComplete As Short <ScaffoldColumn(False)> Public ReadOnly Property FinalPrice As Decimal Get 'If RetailPrice IsNot Nothing OrElse WholesalePrice IsNot Nothing Then If _FinalPrice Is Nothing Then If RetailPrice IsNot Nothing Then _FinalPrice = RetailPrice Else _FinalPrice = WholesalePrice * CommissionMultiplier ' TODO: this should be rounded to the nearest 5th cent so prices don't look weird. End If Dim NormalPart = Decimal.Floor(_FinalPrice.Value) Dim DecimalPart = _FinalPrice.Value - NormalPart If DecimalPart = 0 OrElse DecimalPart = 0.5 Then Return _FinalPrice ElseIf DecimalPart > 0 AndAlso DecimalPart < 0.5 Then DecimalPart = 0.5 ' always rounded up to the nearest 50 cents. ElseIf DecimalPart > 0.5 AndAlso DecimalPart < 1 Then ' Only in this case round down if its about to be rounded up to a valeu like 20, 30 or 50 etc as we want most prices to end in 9. If NormalPart.ToString.LastChr.ToInt = 9 Then DecimalPart = 0.5 Else DecimalPart = 1 End If End If _FinalPrice = NormalPart + DecimalPart End If Return _FinalPrice 'End If End Get End Property <ScaffoldColumn(False)> Public ReadOnly Property DisplayFinalPrice As String Get If _DisplayFinalPrice.IsNullOrEmpty Then _DisplayFinalPrice = FormatCurrency(FinalPrice, 2, TriState.True) End If Return _DisplayFinalPrice End Get End Property Public ReadOnly Property DisplayNormalPrice As String Get If _DisplayNormalPrice.IsNullOrEmpty Then _DisplayNormalPrice = FormatCurrency(NormalPrice, 2, TriState.True) End If Return _DisplayNormalPrice End Get End Property Public ReadOnly Property DivID As String Get Return "pdiv" & ProductID End Get End Property End Class more... i get busted here, with a null reference exception telling me it should contain a value... Dim NormalPart = Decimal.Floor(_FinalPrice.Value)

  • PHP Simple DOM Parser

    - by Junior Coder
    Hi guys I'm using this wonderful class here to do a bit of code embed filtering: http://simplehtmldom.sourceforge.net/. It extends the PHP DOM document class. Pretty much what I am doing is parsing a string through this class that contains embed code, i grab the unique bits of information eg id, width, height send through a handler function which inserts the id, width, height etc into my predefined "safe" template and reinsert my safe template in the place of the embed code the user has put in. May seem a backward way of doing it but it's the way it has to be done :) All of that works fine. Problem is when there is more than just embed code contained in the string, as I can't just replace the embed code i can only replace the entire string which wipes the rest of the tags etc string. For example if there were a p tag that would be wiped. So my question is how using this class can i just replace the certain part of the string? Spent the last few days trying to work this out and need some more input. It appears the class can do this so i'm stumped. Here's a basic version of what i have so far :) // load the class $html = new simple_html_dom(); // load the entire string containing everything user entered here $return = $html->load($string); // check for embed tags if($html->find('embed') == true { foreach($html->find('embed') as $element) { // send it off to the function which returns a new safe embed code $element = create_new_embed($parameters); // this is where i somehow i need to save the changes and send it back to $return } } Any input would be gratefully appreciated. If i have explained my problem well enough please let me know :)

  • Can I use this technique to provide free email service for my users?

    - by Naughty.Coder
    I'll let users register their [email protected] ,,, they enter their members area where they can : 1- send emails ( easy to do) 2- receive emails .. for receiving emails , I'll use a catch all email account , read the email and figure to whom it's sent (username), and then I save it on the database with userid of the username who has registerd ! Do I miss something here ... is it really this simple (if I don't have an email server) ?

  • Objective-C assigning variables question for iphone.

    - by coder net
    The following piece of code can be written in two ways. I would like to know what are the pros and cons of each. If possible I would like to stick with the one liner. 1) UIColor *background = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"Background.png"]]; self.view.backgroundColor = background; [background release]; 2) self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"Background.png"]]; Any issues with releasing memory etc. with #2? I'm new to Objective-C and would like to follow the best approach.

  • How to distribute java components for developers to use?

    - by coder
    I am not sure how to put the correct title. but here is the brief explanation. With Microsoft .NET, i created a server side custom control using C# to be used in ASP.NET pages. I distribute the DLL generated as a component. developers will include that and use in their ASP.NET project. Likewise, how can i do for Java based web components for to use with JSP or JSF or any other java web frameworks?

  • Class/Model Level Validation (as opposed to Property Level)? (ASP.NET MVC 2.0)

    - by Erx_VB.NExT.Coder
    Basically, what the title says. I have several properties that combine together to really make one logical answer, and i would like to run a server-side validation code (that i write) which take these multiple fields into account and hook up to only one validation output/error message that users see on the webpage. I looked at scott guthries method of extending an attribute and using it in yoru dataannotations declarations, but, as i can see, there is no way to declare a dataannotations-style attribute on multiple properties, and you can only place the declarations (such as [Email], [Range], [Required]) over one property :(. i have looked at the PropertiesMustMatchAttribute in the default mvc 2.0 project that appears when you start a new project, this example is as useful as using a pair of pins to check your motor oil - useless! i have tried this method, however, creating a class level attribute, and have no idea how to display the error from this in my aspx page. i have tried html.ValidationMessage("ClassNameWhereAttributeIsAdded") and a variety of other thing, and it has not worked. and i should mention, there is NOT ONE blog post on doing validation at this level - despite this being a common need in any project or business logic scenario! can anyone help me in having my message displayed in my aspx page, and also if possible a proper document or reference explaining validation at this level?

  • if cookies are disabled, does asp.net store the cookie as a session cookie instead or not?

    - by Erx_VB.NExT.Coder
    basically, if cookeis are disabled on the client, im wondering if this... dim newCookie = New HttpCookie("cookieName", "cookieValue") newCookie.Expires = DateTime.Now.AddDays(1) response.cookies.add(newCookie) notice i set a date, so it should be stored on disk, if cookies are disabled does asp.net automatically store this cookie as a session cookie (which is a cookie that lasts in browser memory until the user closes the browser, if i am not mistaken).... OR does asp.net not add the cookie at all (anywhere) in which case i would have to re-add the cookie to the collection without the date (which stores as a session cookie)... of course, this would require me doing the addition of a cookie twice... perhaps the second time unnecessarily if it is being stored in browsers memory anyway... im just trying not to store it twice as it's just bad code!! any ideas if i need to write another line or not? (which would be)... response.cookies.add(New HttpCookie("cookieName", "cookieValue") ' session cookie in client browser memory thanks guys

  • SonarJ like tool for .NET

    - by J. Random Coder
    I'm looking for a tool like SonarJ but for .NET instead of Java. SonarJ helps you to find deviations between he architecture and the code within minutes. It can be integrated into your IDE to help you avoid the introduction of new architetural violations to your code base. You can also use it to maintain metric based software quality rules which will keep complexity under control. I googled and searched SO without satisfying results.

  • Detect HTTPHandler Start

    - by Joe Coder Guy
    Is there a way to detect if a httphandler has started transmitting? I'm trying to do large dynamic Excel Exports (in html table format). I can do this, but there's a long delay from the httphandler getting the message and starting the download. I have turned off the output buffer, so the delay seems to be waiting for the SQL server to dump the data into the sqldataset. Anyways, I'd like to send the user to a new page, have the page display a message, and automatically close once the httphandler has started sending the file. Is there a way to detect if the first file headers have been sent? Many thanks in advance!

  • Just curious, in NetBeans IDE 6.1 how can i get icons for my custom GUI components in the GUI editor

    - by Coder
    This is by no means really important, i was just wondering if the community knows how to put icons for my custom GUI components that show up in the NetBeans GUI designer. What i did was make several Swing components and then i use the menu options to add them to the GUI pallete, but they show up with "?" icons. It would be nice if they showed up with icons similar to swing components such as JButtons, especially for components which are subclassed for Swing components. Thanks!
