• Use of Icons from a GPL'd program

  - by clartaq

  There is a GPL'd program that has some nice icons I would like to use in a project of my own. I would like to release my project under a more liberal license like Apache or BSD. After reading the GPL V3 license (a few times), I can't figure out how it applies to resources like icons. Can I use them at all? If so, must I release my new project under GPL instead of some other license? Of course, I plan to contact the original author and ask them what they had in mind and honor that intent. But what are the legal requirements for use of graphical resources from GPL'd software?

• How do I override ToString in C# enums?

  - by scraimer

  In the post Enum ToString, a method is described to use the custom attribute DescriptionAttribute like this: Enum HowNice { [Description("Really Nice")] ReallyNice, [Description("Kinda Nice")] SortOfNice, [Description("Not Nice At All")] NotNice } And then, you call a function GetDescription, using syntax like: GetDescription<HowNice>(NotNice); // Returns "Not Nice At All" But that doesn't really help me when I want to simply populate a ComboBox with the values of an enum, since I cannot force the ComboBox to call GetDescription. What I want has the following requirements: Reading (HowNice)myComboBox.selectedItem will return the selected value as the enum value. The user should see the user-friendly display strings, and not just the name of the enumeration values. So instead of seeing "NotNice", the user would see "Not Nice At All". Hopefully, the solution will require minimal code changes to existing enumerations. Obviously, I could implement a new class for each enum that I create, and override its ToString(), but that's a lot of work for each enum, and I'd rather avoid that. Any ideas? Heck, I'll even throw in a hug as a bounty :-)

• Specification: Use cases for CRUD

  - by Mario Ortegón

  I am writing a Product requirements specification. In this document I must describe the ways that the user can interact with the system in a very high level. Several of these operations are "Create-Read-Update-Delete" on some objects. The question is, when writing use cases for these operations, what is the right way to do so? Can I write only one Use Case called "Manage Object x" and then have these operations as included Use Cases? Or do I have to create one use case per operation, per object? The problem I see with the last approach is that I would be writing quite a few pages that I feel do not really contribute to the understanding of the problem. What is the best practice?

• What's the funniest user request you've ever had?

  - by Shaul

  Users sometimes come up with the most amusing, weird and wonderful requirements for programmers to design and implement. Today I read a memo from my boss that we need the "ability to import any excel or access data, irrespective of size, easily and quickly." From the same memo, we have a requirement to "know if anyone unauthorized accessed the system" - as if a hacker is going to leave his calling card wedged between an index and a foreign key somewhere. I think my boss has been watching too much "Star Trek"... :) What's the funniest user request you've ever had?

• How would you start automating my job? - Part 2

  - by Jurily

  (Followup to this question) After surviving the first wave of incoming shipments (9 hours of copy/paste), I now believe I have all the requirements. Here is the updated workflow: Monkey collects email attachments (4 Excel spreadsheets, 1 PDF) Monkey creates central database, does complex calculations (right now this is also an Excel spreadsheet) Monkey sends data to two bosses, who set the retail prices independently; first one to reply wins Monkey sends order form to our other warehouses, also Excel Monkey sends spreadsheets to VIP customers, carefully sanitized and formatted (4 different discount categories) Jurily enters the data into the accounting system. I've given up on automating this part, there's too much business logic involved, and the database is a pile of sh^W legacy My question: What technologies would you use for a quick and dirty solution? I'm mostly sold on C#, but coming from a Linux/C++ background, I'm horribly confused about my choices in Microsoft-land. For bonus points: How would you redesign the whole system from the ground up? P.S. in case you were wondering, my job title is System Administrator.

• mediawiki markup equivalent of WMD editor?

  - by Justin Grant

  Anyone have a recommendation for an editor like the WMD editor, but using MediaWiki markup instead of Markdown? Our site is already using MediaWiki markup but we want a slicker editor without changing markup completely. Requirements include: live preview of formatted text underneath the markup you're typing a toolbar for common formatting (bold, italic, links, bullets, numbered-list, code, etc) keyboard shortcuts for each toolbar button (e.g. CTRL+B for bold) Undo/redo via keyboard shortcuts (CTRL+Z/CTRL+Y) or toolbar buttons works well in the usual set of popular browsers (including IE6!) open-source would be preferred

• Is it possible to modify ASP.NET to no longer require runat="server"?

  - by sean2078

  I know why runat="server" is currently required (ASP.NET why runat="server"), but the consensus is that it should not be required if you incorporate a simple default into the design (I agree of course). Would it be possible to modify, extend, decompile and recreate, intercept or otherwise change the behavior of how ASP.NET parses ASPX and ASCX files so that runat="server" would no longer be required? For instance, I assume that a version of Mono could be branched to accomplish this goal. In case specific requirements are helpful, the following highlights one design: During parsing, when configured namespace tags are encountered (such as "asp"), default the element's runat property to "server" During parsing, when configured namespace tags are encountered (such as "asp"), if the element's runat property value is available, then that value should be used in place of the default New page-level setting introduced (can be set in the page directive or web.config) that specifies the default runat value for a specific namespace tag

• .NET 2d library for circuit diagrams

  - by Dinah

  I want to draw and manipulate logic flow (as opposed to analog) circuit diagrams and I'm trying not to reinvent the wheel. Problems like positioning, line drawing, line crossing and connecting, path finding, rubberband lines, and drag & drop are also identical in flow charts, UML diagrams, or class diagrams so I started by viewing related topics via Google and Stack Overflow. However, the following requirements seemed to keep me from finding anything that quite fit: assuming a chip has an image with input and output stubs, the connecting lines would connect to the chip only in the exact spots of the I/O stubs the color of connecting lines are able to be set as per a chip's output Is there an existing .NET 2d graphics library that would be suitable for drawing circuit diagrams?

• In app purchases in Android.

  - by Samuh

  I have an application that comes bundled with some content(say image, songs etc.). We want to have an in-app store, so that the user can buy contents and extend the experience. What are the different ways in which the above mentioned can be achieved? iPhone has Storekit framework that enables in-app purchases. So, our requirements wants us to follow the suit. Also, according to Android Markets(AM) distribution agreement, an Android application published via AM, is not allowed to accept payments from any Payment collectors other than the one Market provides and/or Google checkout. We have decided to integrate Paypal, now that they have published Mobile Payments Library to Android developers. If we do so, can we publish our application on Android Market?

• Getting "longnamesfirst" option to work with natbib in LaTeX - custom .bst

  - by jkale

  Hey all, I'm writing an MSc dissertation and I'm having difficulty getting the longnamesfirst option working in natbib. My University has a very specific referencing style a little like APA, but not quite the same. I've used the docstrip utility to build a basic framework and then edited it to fit the requirements of my University. Having tested it with the simplest possible document; applying my bst then trying it again with one of the defaults (\bibliographystyle{apacite}) I can see than natbib works as intended with apacite. It doesn't however produce correct results with my bst. So my question: How does the .bst file link with natbib to enforce the "longnamesfirst" option?

• Version control for Adobe Flash projects

  - by Guss

  I'm working with a very complex Flash project which is part of a full range of services that we deploy for the use of our clients. For most of our software sources (Java, PHP, Javascript, HTML and a some supporting scripts in other languages) we use subversion for version control and management, so we do the same for our Flash projects, even though we gain little benefits from version controlling that (except being able revert to previous versions) as FLA files are stored as just binaries which we cannot get meaningful diffs from. We're putting as much code as we can into AS files which we can properly manage using subversion, but due to the requirements of our architecture and our deployment strategy (both we cannot change because of our clients needs), we still maintain a large collection of FLA files that we need to manage. I've looked at Adobe Version Cue and while I do not really understand what it does in terms of version control, will moving our Flash projects to hosting on Version Cue will give me better control then I currently get from Subversion? Also - if people can share their experience and suggestions regarding version control of Flash projects, it will be very helpful.

• iTunes Connect: Excluding iPad From Supported Devices

  - by mattmccomb

  I have just uploaded my first app to iTunes Connect and noticed that my list of supported devices is appearing as follows... Device Requirements : Compatible with iPhone, iPod touch, and iPad. I've developed specifically for the iPhone and iPod Touch and have not yet done any testing on the iPad simulator. I therefore don't want the app submission testers to try running my app on an iPad and rejecting it because of some minor issue. I've looked at setting the required device capabilities in my info.plist, but that doesn't appear to allow me to restrict at a device level. Is this a by-product of building using the 3.1.3 SDK? Are apps built using this SDK automatically upscaled to work on the iPad?

• As a consultant should I charge my clients for developing specs?

  - by Chris

  I'm trying to transition into some programming consulting work. A friend of my former employer is interested in having me "develop a spec," which I take to mean come up with some technology requirements and time estimates (e.g. milestones). Do developers normally charge for this? I'm imagining it's basically the same kind of workload that creating a bid for a project would take. On one hand, consultants don't get paid for the time they put into the legwork of a bid. On the other hand, this is probably go to be more than a couple hours of work, and my time is valuable. Any advice? Any sites besides SO I could go to get advice with this kind of stuff? (Sorry if this isn't programming-related enough for StackOverflow! I don't know where else to get advice!)

• Slowness of Netbeans Platform Apps - how to mitigate?

  - by user559298

  Hi, We are developing a commerical application (pretty complex) in java using Netbeans IDE. We have 2 options in netbeans to create it- 1. Develop Java desktop app 2. Netbeans Platform app We have requirement that application startup and response times should be very very fast, should be modular etc. We did Proof of Technology by creating apps using both approaches mentioned above. We found Netbeans platform apps are very slow during startup and during screen navigation compared to pure Swing based desktop apps. We tried to implement suggestions provided at http://wiki.netbeans.org/Category:Performance:FAQ and in other blogs and forums to improve on speed of the app but were not successful. We feel for creating a complex desktop app Netbeans platform app would be better suited, but its not meeting our performance requirements (startup and response times, memory footprints, CPU usage guidelines etc). Can any one guide us on how to mitigate our problem of improving performance of Netbeans Platforms apps? Thanks in advance for your help. -bhan

• UML tool required for C#

  - by Peter Morris

  I need some help - here are my requirements. 1: I should be able to modify the UML model without affecting the code, and then later apply the changes. This is because I need to print the changes, get them confirmed, and then develop them. 2: I should be able to reuse parts of the model. For example I would create one project which outputs A.dll assembly, and then another UML project would use the classes in the first to crate B.dll 3: Project stored as text so I can see changes in version control history. 4: Together is too expensive :-)

• Should I be building GUI applications on Windows using Perl & Tk?

  - by CheeseConQueso

  I have a bunch of related Perl scripts that I would like to put together in one convenient place. So I was thinking of building a GUI and incorporating the scripts. I'm using Strawberry Perl on Windows XP and have just installed Tk from cpan about fifteen minutes ago. Before I go for it, I want some sound advice either for or against it. My other option is to translate the Perl scripts into VB and use Visual Studio 2008, but that might be too much hassle for an outcome that might end up all the same had I just stuck with Perl & Tk. I haven't looked yet, but maybe there is a module for Visual Studio that would allow me to invoke Perl scripts? The main requirements are: It must be able to communicate with MySQL It must be able to fetch & parse XML files from the internet It must be transportable, scalable, and sustainable What direction would you take?

• Performance statistics hooks

  - by tinny

  Lets be honest, most software that developers produce has quite modest performance requirements. E.g. Systems perhaps serving 100's of requests per second, if that. But lets assume for a moment (or even dream) that you where perhaps involved in the "next big thing" (whatever that means) and you wanted to put some sort of performance statistics logging in place to help you out when all those users come flying in. Performance statistics logging, how would you approach this requirement? Perhaps you would use some sort of generic framework for this? Or roll your own solution? What would you log? How granular? Or would you not even bother putting anything in place and rather deal with this issue when it actually became an issue? It would be really interesting to hear your thoughts on this topic.

• Best way to provide software settings?

  - by claws

  I'm using C# .NET. In my software I'm providing settings dialog through which user can set the application settings which I want to save to a file. Requirements (typical): Every class I defined uses some part of these settings. So, these should be global to all classes. These should be loaded while software is started. When ever user changes settings and clicks 'save'/'apply'. Current settings should change. I am wondering what is the best way to do this? Also, what is the best way to save these settings to disk? I mean should I create a Settings class object and serializing it to 'settings.dat' or provide an structured file like XML/JSON

• How to create a tree with filtered nodes from drupal taxonomy.

  - by sprugman

  I'm trying to create a menu tree in drupal like this: - term 1 node 1 node 2 - sub-term 1 node 3 node 4 + sub-term 2 - sub-term 3 node 5 - sub-sub-term 1 node 6 + term 2 etc. (Sub-term 2 and term 2 are toggled closed.) Some requirements: Output this using something like JQuery Menu to get an interactive tree Filter the nodes by cck type Filter the nodes by cck field Only have terms with nodes or other active terms in them show up Mark the current node as such, and automatically open the tree to that point Do I have to write this myself, or are there a combination of modules that can do it? I've got Advanced Taxonomy Blocks, which is pretty close, but it doesn't list the nodes.

• What is proper way to detect all available serial ports on Windows?

  - by Sorin Sbarnea

  There are several ways to list serial ports under Windows but I'm not sure what is the proper way: the way that does detect all serial ports that are available. One good code example is http://www.naughter.com/enumser.html - where there at 9 (nine!) ways of enumerating serial devices. The question is: what is the optimal way of doing it. Requirements: * to not open ports in order to check if they are available. * to be able to detect ports with different names than COMx.
