  • Best approach for utility class library using Visual Studio

    - by gregsdennis
    I have a collection of classes that I commonly (but not always) use when developing WPF applications. The trouble I have is that if I want to use only a subset of the classes, I have three options: Distribute the entire DLL. While this approach makes code maintenance easier, it does require distributing a large DLL for minimal code functionality. Copy the classes I need to the current application. This approach solves the problem of not distributing unused code, but completely eliminates code maintenance. Maintain each class/feature in a separate project. This solves both problems from above, but then I have dramatically increased the number of files that need to be distributed, and it bloats my VS solution with tiny projects. Ideally, I'd like a combination of 1 & 3: A single project that contains all of my utility classes but builds to a DLL containing only the classes that are used in the current application. Are there any other common approaches that I haven't considered? Is there any way to do what I want? Thank you.

  • What should developers know about Windows executable binary file compression?

    - by Peter Turner
    I'd never heard of this before, so shame on me, but programs like UPX can compress my files by 80% which is totally sweet, but I have no idea what the the disadvantages are in doing this. Or even what the compressor does. Website linked above doesn't say anything about dynamically linking DLLs but it mentions about compressing DESCENT 2 and about compressing Netscape 4.06. Also, it doesn't say what the tradeoffs are, only the benefits. If there weren't tradeoffs why wouldn't my linker compress the file? If I have an environment where I have one executable and 20-30 DLL's, some of which are dynamically loaded an unloaded fairly arbitrarily, but not in loops (hopefully), do I take a big hit in processing time decompressing these DLL's when they're used?

  • How to elevate engineering culture at large corporations?

    - by davidk01
    One thing I have realized working at a large corporation is that it doesn't matter how smart you are because if everyone else doesn't see the value in what you are doing then you are not going to get very far. It's much harder to convince 1000 people that a certain part of the software stack should be in groovy than it is to convince 10 people of the same thing. I'm curious how people go about elevating the engineering culture at large corporations because I've been running into walls left and right and I would like to be more proactive about how I go about it. I have been advocating tech talks and tech demos along with code reviews as potential solutions. Do people have other suggestions? Note that 1000 people and groovy are just representative examples. I am not married to groovy or any other language and 1000 people is meant to indicate large scale and how to go about teaching a large group of people about best practices and engineering principles in general.

  • Cross platform mobile development VS Native Mobile Development: Present And Future.

    - by MobileDev123
    I just completed one year in Smart phone development, working on BlackBerry and Android and also developed one application exclusively targeted to nokia feature phones. And just a month ago I come to know about Titanium Appcelerator tool that enables cross platform development, but there are some developers who complain about it's sub-par functionalities. Even a little bit experience of mine says that developing in native environment rather than these cross platform tools will give you more advantages by giving a developer a chance to add more features with better performance. Do you have same experience? Or you find such cross development tools really useful regarding to advance functionality and performance? As porting (or co developing) same application to different mobile platform is common thing nowadays, what do you think will these cross platform tools evolve and force developers to get a hands on approach on them or majority will stick to the native development environment?

  • How to credit other authors in an open source project

    - by erik
    I have a pet project that I am planning to release as open source at some point in the not-too-distant future. A couple of the files use or are mostly code that was taken from a project released under the New BSD License. While I have changed it to fit my needs and added some small stuff, the algorithm and the functionality is basically exactly the same. I want to make sure that the author of the code gets credit and that the license is not broken, but I also want to make the reader aware that this is not the code as it was orignally released. How should I approach this? Should I isolate the code as much as possible and just retain the original license? Maybe put all the files that contain foreign code in their own folder and add a readme explaining what has been added/removed? There must have been tons of projects using other open source code. What is the standard approach to this?

  • Designing binary operations(AND, OR, NOT) in graphs DB's like neo4j

    - by Nicholas
    I'm trying to create a recipe website using a graph database, specifically neo4j using spring-data-neo4j, to try and see what can be done in Graph Databases. My model so far is: (Chef)-[HAS_INGREDIENT]->(Ingredient) (Chef)-[HAS_VALUE]->(Value) (Ingredient)-[HAS_INGREDIENT_VALUE]->(Value) (Recipe)-[REQUIRES_INGREDIENT]->(Ingredient) (Recipe)-[REQUIRES_VALUE]->(Value) I have this set up so I can do things like have the "chef" enter ingredients they have on hand, and suggest recipes, as well as suggest recipes that are close matches, but missing one ingredient. Some recipes can get complex, utilizing AND, OR, and NOT type logic, something like (Milk AND (Butter OR spread OR (vegetable oil OR olive oil))) and I'm wondering if it would be sane to model this in a graph using a tree type representation? An example of what I was thinking is to create three "node" types of AND, OR, and NOT and have each of them connect to the nodes value underneath. How else might this be represented in a Graph Database or is my example above a decent representation?

  • Implementation of instance testing in Java, C++, C#

    - by Jake
    For curiosity purposes as well as understanding what they entail in a program, I'm curious as to how instance testing (instanceof/is/using dynamic_cast in c++) works. I've tried to google it (particularly for java) but the only pages that come up are tutorials on how to use the operator. How do the implementations vary across those langauges? How do they treat classes with identical signatures? Also, it's been drilled into my head that using instance testing is a mark of bad design. Why exactly is this? When is that applicable, instanceof should still be used in methods like .equals() and such right? I was also thinking of this in the context of exception handling, again particularly in Java. When you have mutliple catch statements, how does that work? Is that instance testing or is it just resolved during compilation where each thrown exception would go to?

  • Why was Android's ContentProvider created?

    - by satur9nine
    The title sums up my question, but to elaborate basically what I want to understand is why the Android designers want apps that need to work with shared data to use a Content Provider rather than just accessing the SQLite database directly? The only reason I can think of is security because certain files can by accessed only be certain processes and in that way the Content Provider is the gatekeeper that ensures each app has the proper privileges before allowing read and/or write access to the database file. Is that the primary reason why ContentProvider was created?

  • How much is modern programming still tied to underyling digital logic?

    - by New Talk
    First of all: I've got no academic background. I'm working primarily with Java and Spring and I'm also fond of web programming and relational databases. I hope I'm using the right terms and I hope that this vague question makes some sense. Today the following question came to my mind: How much is modern programming still tied to the underlying digital logic? With modern programming I mean concepts like OOP, AOP, Java 7, AJAX, … I hope you get the idea. Do they no longer need the digital logic with which computers are working internally? Or is binary logic still ubiquitous when programming this way? If I'd change the inner workings of a computer overnight, would it matter, because my programming techniques are already that abstract? P. S.: With digital logic I mean the physical representation of everything "inside" the computer as zeroes and ones. Changed "binary" to "digital".

  • How do functional languages handle random numbers?

    - by Electric Coffee
    What I mean about that is that in nearly every tutorial I've read about functional languages, is that one of the great things about functions, is that if you call a function with the same parameters twice, you'll always end up with the same result. How on earth do you then make a function that takes a seed as a parameter, and then returns a random number based on that seed? I mean this would seem to go against one of the things that are so good about functions, right? Or am I completely missing something here?

  • Is "no installation" software a good thing?

    - by Yaron Naveh
    I am building an application that will, hopefully, be used by developers. To be appealing to developers I want it to be lightweight, small in size, and with no installation (e.g. xcopy). I trust more an application without installation to not put garbage in my registry, to be lightweight etc. My friend thinks the opposite: An installer puts shortcuts on the desktop / menu for me, it ensures cleanup via the uninstaller, and seems more official. I'm curious - what is everyone's take on this?

  • I'm learning html and I'm confused as to how href's work. [migrated]

    - by Robolisk
    Okay so i'm learning html right now and soon css. In my html coding I have a section like this for navigation: <div id="header"> <h1>Guild Wars 2 Fanbase</h1> <ol id="navigation"> <li><a href="/">Home</a></li> <li><a href="/facts">Facts</a></li> <li><a href="/gallery">Gallery</a></li> <li><a href="/code">Coding</a> <ul><li><a href="/code/line">Lines</a></li> <li><a href="/code/comment">Comment Lines</a></li> </ul> </li> </ol></div> Now when I open up this .html file this is all layed out the way I want it too look (the mark up that is). My question is this, when I click on a link on this site (this site being this code) I get an a error saying this webpage is not found, but of course. But how do I create it so I can have the web pages working together? I'm not sure how to word it correctly. Like, do I create another .html file in the same directory so somehow when I click the link it reads from the second .html file? If you not sure what I'm asking, just let me know and I'll try to be more specific. Thank you for your help (: excuse my mistakes in grammar, not the worlds best in English, trying my best (:

  • Convert filenames to their checksum before saving to prevent duplicates. Is is a smart thing to do?

    - by Xananax
    TL;DR:what the title says I am developing some sort of image board in PHP. I was thinking of changing each image's filename to it's checksum prior to saving it. This way, I might be able to prevent duplicates. I know this wouldn't work for two images that are the same but differ in size or level of compression or whatnot, but this method would allow for an early check. What bugs me is that I never saw this method implemented anywhere, so I was wondering if there is a catch to it. Maybe it is just more efficient to keep the original filename and store the hash in DB? Maybe the whole method is just not useful and my question is moot? What do you think? On a side note, I don't really get how hashes are calculated so I was wondering, if my first question checks out, if it would be possible to calculate the likeness that two images are similar by comparing hashes (levenshtein or something of the sort).

  • As a web designer, which language should I learn first for my feature career? (PHP or JavaScript) [closed]

    - by kdevs3
    Possible Duplicates: Best Programming Language for Web Development How can I choose a web development language? What language will you choose if you are going to build something big? What is the right option of programming languages and tools for building our website? What is the easiest web programing language at....? Well, I'm more of a basic web designer. I know the easy stuff pretty well. (Ya know, html, css) But I've been trying to take it to the next step and I'm contemplating about what I should learn that will help me out the most in my future web design/programming career, should it be JavaScript or maybe I should try to learn a back end programming language such as PHP. Lately, I have been hearing about a lot how JavaScript is so great and useful now, because of libraries such as jQuery and what possibility's it can bring by using Node.js and other frameworks. I've only learned the most basic of JavaScript and used some jQuery (mostly plugins) so i wouldn't know at all of what it can actually do. Would JS being so popular as it is now and useful, be a reason to stick with JavaScript and only learn it that for now? Or as a web designer, how important would it be to learn how to make a web application/website operate and functional, and know how to work with servers, etc? (Such as getting forms to work and sending data to the server and back) I've took a look at frameworks such as Code Igniter before, and looks really simple to get started with if I try to learn PHP, But I'm not sure how important it is for my career and what I would gain out of it. I'm asking because I can't decide what I should learn first. When I select it, I really want to take my time and learn the language. I don't want to spend time on learning multiple languages at the same time, so I need to pick wisely. I'm trying to turn the right direction so my career can hopefully be successful in the feature. (If money/gaining a job asked if its important, then its a yeah, it is a bit) I'm hoping I can get opinions and suggestions on this question, thanks for giving me your thoughts also.

  • Term for unit testing that separates test logic from test result data

    - by mario
    So I'm not doing any unit testing. But I've had an idea to make it more appropriate for my field of use. Yet it's not clear if something like this exists, and if, how it would possibly be called. Ordinary unit tests combine the test logic and the expected outcome. In essence the testing framework only checks for booleans (did this match, did the expected result result). To generalize, the test code itself references the audited functions, and also explicites the result values like so: unit::assert( test_me() == 17 ) What I'm looking for is a separation of concerns. The test itself should only contain the tested logic. The outcome and result data should be handled by the unit testing or assertion framework. As example: unit::probe( test_me() ) Here the probe actually doubles as collector in the first run, and afterwards as verification method. The expected 17 is not mentioned in the test code, but stored or managed elsewhere. How is this scheme called? Or how would you call it? I hope I can find some actual implementations with the proper terminology. Obviously such a pattern is unfit for TDD. It's strictly for regression testing. Also obviously, it cannot be used for all cases. Only the simpler test subjects can be analyzed that way, for anything else the ordinary unit test setup and assertion steps are required. And yes, this could be manually accomplished by crafting a ResultWhateverObject, but that would still require hardwiring that to the test logic. Also keep in mind that I'm inquiring for use with scripting languages, and not about Java. I'm aware that the xUnit pattern originates there, and why it's hence as elaborate as it is. Btw, I've discovered one test execution framework which allows for shortening simple test notations to: test_me(); // 17 While thus the result data is no longer coded in (it's a comment), that's still not a complete separation and of course would work only for scalar results.

  • Choice the project pattern, advice for this case

    - by Lucas Rodrigues Sena
    I have a project in MVC4 entity framework, and have to adapt it to possible updates on the dlls and system do not stop work. I'm using portable Areas, but have difficulty creating 5 modules and about 5 functionality for each modules with fully functioning independently as a dll and database. 1- Reflection DLLs, the system works "on the fly". (I cant do it on mvc4 at moment). 2- Portables Areas (I need to do one area for each modules*functionality 5*5 Areas). Confuse way and I'm afraid if this is ridiculous. 3- Implement WFC on MVC4, compatible? 4- Other better way?

  • How do I convince my team that a requirements specification is unnecessary if we adopt user-stories?

    - by Nupul
    We are planning to adopt user-stories to capture stakeholder 'intent' in a lightweight fashion rather than a heavy SRS (software requirements specifications). However, it seems that though they understand the value of stories, there is still a desire to 'convert' the stories into an SRS-like language with all the attributes, priorities, input, outputs, source, destination etc. User-stories 'eliminate' the need for a formal SRS like artifact to begin with so what's the point in having an SRS? How should I convince my team (who are all very qualified CS folks by the way - both by education and practice) that the SRS would be 'eliminated' if we adopted user-stories for capturing the functional requirements of the system? (NFRs etc can be captured too, but that's not the intent of the question). So here's my 'work-flow' argument: Capture initial requirements as user-stories and later elaborate them to use-cases (which are required to be documented at a low level i.e. describing interactions with the UI prototypes/mockups and are a deliverable post deployment). Thus going from user-stories to use-cases rather than user-stories to SRS to use-cases. How are you all currently capturing user-stories at your workplace (if at all) and how do you suggest I 'make a case' for absence of SRS in presence of user-stories?

  • How to teach computer science ?

    - by proferikson
    I am just starting to teach computer science. It's just the basic level. I'm finding that I sometimes don't know how to approach topics in a way that lets students easily understand. I've found that the best thing is to use analogies. A terrible one, that worked well, was presenting recursion by using the process of eating a burger. (You eat one bite, then you eat the rest). Interesting real world examples do wonders here. I'd like to know the techniques you have used for teaching, or teachers you've had have used that proved particularly effective. I'd also like to know your best analogies and examples for topics in CS101, especially for those harder to grasp topics. I'm teaching the class in Java (as required).

  • Where could Distributed Version Control Systems currently be in Gartner's hype cycle?

    - by dukeofgaming
    Edit: Given the recent downvoting (+8/-6 at this point) it was made clear to me that Gartner's lifecycle is a biased metric from a programmer's perspective. This is something that is part of a paper I'm going to present to management, and management types are part of Gartner's audience. Giving DVCS exposure & enthusiasm (that "could" be deemed as hype, or at least attacked as such), think about the following question when reading this one: "how could I use Gartner's hype cycle to convince management that DVCSs are ready (or ready-enough) for us, and that it is not just hype" Just asking if DVCSs is hype wouldn't be constructive, Gartner's hype cycle is a more objective instrument than just asking that (even if this instrument is regarded as biased). If you know any other instrument please, by all means, mention it. Edit #2: I agree that Gartner's Life Cycle is not for every technology, but I consider it may have generated enough buzz to be considered hype by some, so it maybe deserves to be at least evaluated/pondered as such by using this instrument in order to prove/disprove it to whatever degree. I'm an advocate of DVCS, BTW. I'm doing research for a whitepaper I'm writing in favor of DVCS adoption at company and I stumbled upon the concept of social proof. I want to prove that the social proof of DVCS adoption is not necessarily cargo cult and doing further research I now stumbled upon Gartner's hype cycle which describes technology maturity in 5 phases. My question is: what could be an indicator of the current location of Distributed Version Control Systems (I mean git, mercurial, bazaar, etc. in general) at a particular phase in the hype cycle?... in other (less convoluted) words, would you say that currently expectations of DVCSs are a) starting, b)inflated, c)decreasing (disillusionment), d)increasing (enlightenment) or e)stabilizing (mature) and (more importantly) why? I know it is a hard question and there is subjectivity involved, but I'll grant the answer (and the traditional cookie) to the clearest argument/evidence for a particular phase.

  • How do I speed up XML parsing operation?

    - by absentx
    I currently have a php script set up to do some xml parsing. Sometimes the script is set as an on page include and other times it is accessed via an ajax call. The problem is the load time for this particular page is very long. I started to think that the php I had written to find what I need in the XML was written poorly and my script is very resource intense. After much research and testing the problem is indeed not my scripting (well perhaps you could consider it a problem with my scripting), but it looks like it takes a long time to load the particular xml sources. My code is like such: $source_recent = 'my xml feed'; $source_additional = 'the other feed I need'; $xmlstr_recent = file_get_contents($source_recent); $feed_recent = new SimpleXMLElement($xmlstr_recent); $xmlstr_additional = file_get_contents($source_additional); $feed_additional = new SimpleXMLElement($xmlstr_additional); In all my testing, the above code is what takes the time, not the additional processing I do below. Is there anyway around this or am I at the mercy of the load time of the xml URL's? One crazy thought I had to get around it is to load the xml contents into a db every so often, then just query the db for what I need. Thoughts? Ideas?

  • How can I select an appropriate licensing/obfuscation system for .NET?

    - by Adam
    I saw someone suggesting .NET Reactor once as a good obfuscator. I went to their website to check it out and saw they have a product called IntelliLock which is advertised as a pretty robust licensing system which has code protection/obfuscation built in. With that said, I tried to contact them and ask them a few questions regarding the product, but have not had any response. This is kind of a red flag for me. However, it seems like there is some user base for this product whom are satisfied. What .NET licensing system(s) with .NET code protection/obfuscation are you using? What are its pros & cons that you have encountered? Are there things I should be looking for or looking to avoid when evaluating these systems?

  • Agile and different facet of software development

    It is said that the Kanban methodology is suited for software maintenance and support areas, whereas Scrum is more suited for new product development. No process or methods are complete. Using the right one will help you succeed, but they will not guarantee success. Which agile approach is best suited for a project which is basically a re-platforming from one technology to another (say from Java to .NET).

  • LaTeX-like display programming environment

    - by Gage
    I used to be a hobbyist programmer, but now I'm also a fairly experienced physicist and find myself programming to solve certain problems quite a lot. In physics, we use variables with superscripts, subscripts, italics, underlines, etc etc. To bridge this gap to the computer we usually use LaTeX. Now, I generally use MATLAB for handling any data and such, and find it very irritating that I can't basically use LaTeX for variable names. Something as simple as sy has to be named either sigma_y or some descriptive name like peak_height_error. I don't necessarily want full on workable LaTeX in my code, but I do want to be able to use greek letters and super/sub-scripts at the very least. Does this exist?
