  • Is it possible to use RubyGnome2's/QtRuby's HTML renderers to make UI for a Ruby script?

    - by mjr
    I'd like to make a graphical user interface for my script, instead of running it from the console. I'm aware there's a wealth of UI libraries for Ruby, but I'm quite familiar with HTML and CSS and I'd like to use them for building an interface. So the question is: Is it possible to use a HTML rendering library to make such an UI? From what I understand, it's relatively easy to put in a HTML rendered view of something, but is it possible to communicate back with the script? Like when I push that big red button, it actually tells the script to act on it? Obviously it's possible if the script run on the server side, but I'd like to run it as a desktop application.

  • Functional Languages that compile to Android's Dalvik VM?

    - by Berin Loritsch
    I have a software problem that fits the functional approach to programming, but the target market will be on the Android OS. I ask because there are functional languages that compile to Java's VM, but Dalvik bytecode != Java bytecode. Alternatively, do you know if the dx utility can intelligently convert the .class files generated from functional languages like Scala? Edit: In order to add a bit more helpfulness to the community, and also to help me choose better, can I refine the question a bit? Have you used any alternate languages with Dalvik? Which ones? What are some "gotchas" (problems) that I might run into? Is performance acceptable? By that, I mean the application still feels responsive to the user. I've never done mobile phone development, but I grew up on constrained devices and I'm under no illusion that there is a cost to using non-standard languages with the platform. I just need to know if the cost is such that I should shoe-horn my approach into default language (i.e. apply functional principles in the OOP language).

  • Teaching myself, as a physicist, to become a better programmer

    - by user787267
    I've always liked physics, and I've always liked coding, so when I got the offer for a PhD position doing numerical physics (details are not relevant, it's mostly parallel programming for a cluster) at a university, it was a no-brainer for me. However, as most physicists, I'm self taught. I don't have broad background knowledge about how to code in an object oriented way, or the name of that specific algorithm that optimizes the search in some kD tree. Since all my work so far has been more concerned about the physics and the scientific results, I undoubtedly have some bad habits - more so because my coding is my own, and not really teamwork. I have mostly used C since it is very straightforward and "what you write is what you get" - no need for fancy abstractions. However, I have recently switched to C++ since I'd like to learn more about the power that comes with abstraction, and it's pretty C-like (syntax-wise at least). How do I teach myself to code in a good, abstract way like a graduate in computer science? I know my code is efficient, but I want it to be elegant as well, and readable. Keep in mind that I don't have time to read several 1000-page tomes about abstract programming. I need to spend time on actual, physics related research (my supervisor would laugh at me if he knew I spent time thinking about how to program elegantly). How do I assess if my work is also good from a programmer's perspective?

  • How can we make agile enjoyable for developers that like to personally, independently own large chunks from start to finish

    - by Kris
    We’re roughly midway through our transition from waterfall to agile using scrum; we’ve changed from large teams in technology/discipline silos to smaller cross-functional teams. As expected, the change to agile doesn’t suit everyone. There are a handful of developers that are having a difficult time adjusting to agile. I really want to keep them engaged and challenged, and ultimately enjoying coming to work each day. These are smart, happy, motivated people that I respect on both a personal and a professional level. The basic issue is this: Some developers are primarily motivated by the joy of taking a piece of difficult work, thinking through a design, thinking through potential issues, then solving the problem piece by piece, with only minimal interaction with others, over an extended period of time. They generally complete work to a high level of quality and in a timely way; their work is maintainable and fits with the overall architecture. Transitioning to a cross-functional team that values interaction and shared responsibility for work, and delivery of working functionality within shorter intervals, the teams evolve such that the entire team knocks that difficult problem over. Many people find this to be a positive change; someone that loves to take a problem and own it independently from start to finish loses the opportunity for work like that. This is not an issue with people being open to change. Certainly we’ve seen a few people that don’t like change, but in the cases I’m concerned about, the individuals are good performers, genuinely open to change, they make an effort, they see how the rest of the team is changing and they want to fit in. It’s not a case of someone being difficult or obstructionist, or wanting to hoard the juiciest work. They just don’t find joy in work like they used to. I’m sure we can’t be the only place that hasn’t bumped up on this. How have others approached this? If you’re a developer that is motivated by personally owning a big chunk of work from end to end, and you’ve adjusted to a different way of working, what did it for you?

  • Looking for an open source project in Python

    - by Roman Yankovsky
    I am looking for practical tasks to get experience with Python. Just reading the books and not doing any tasks in the language is not effective. I solved some problems on the Project Euler and TopCoder and it helped me to learn the syntax of the language better. But those tasks are hard algorithmically, but as a rule is quite simple from the point of view of programming. Now I'm looking for an interesting open source project in Python, participation in which will help me to better understand the OO-model of language. Although, this is my first step with Python, in general, I am an experienced programmer and I can be useful for a project. May be someone can suggest something?

  • Execute code every hour

    - by Linger
    I need to create a web service that executes every hour. It will be used to review data in a database and add alerts to a table in the same database if certain conditions are met/not met. What we currently have is: We have end devices that use Python to report to an Amazon Web Services (AWS) virtual server. The AWS server takes that information and stores it in a MySQL database. The AWS server is Linux running Django and Apache. I need to be able to have some python code run every hour that verifies the data that has been stored by the end devices. If certain conditions are not met then a record will be added to the alerts table in the database. We originally contracted to have the above setup created. I am new to Python, Django, and Apache. However, I have already made several changes to the Python code that sends and also receives the data from the end devices. I am a coder that is breaking into web programming. Does anyone have any recommendations on how I can do this?

  • What's so difficult about SVN merges? [closed]

    - by Mason Wheeler
    Possible Duplicate: I’m a Subversion geek, why should I consider or not consider Mercurial or Git or any other DVCS? Every once in a while, you hear someone saying that distributed version control (Git, HG) is inherently better than centralized version control (like SVN) because merging is difficult and painful in SVN. The thing is, I've never had any trouble with merging in SVN, and since you only ever hear that claim being made by DVCS advocates, and not by actual SVN users, it tends to remind me of those obnoxious commercials on TV where they try to sell you something you don't need by having bumbling actors pretend that the thing you already have and works just fine is incredibly difficult to use. And the use case that's invariably brought up is re-merging a branch, which again reminds me of those strawman product advertisements; if you know what you're doing, you shouldn't (and shouldn't ever have to) re-merge a branch in the first place. (Of course it's difficult to do when you're doing something fundamentally wrong and silly!) So, discounting the ridiculous strawman use case, what is there in SVN merging that is inherently more difficult than merging in a DVCS system?

  • How do you safely comment out code in Visual Studio and TFS?

    - by burnt1ce
    Once in a while, a co-worker check-ins bad code and this blocks you from your application from initializing properly so you can continue doing your work. To get around this problem quickly, I've commented out the offending code. I accidentally to uncomment out the offending code at the time of check-in and I want to prevent this from happening again. Do you have a trick to 1) disable bad code that stop you from working 2) prevent yourself from checking in unwanted changes? I'm currently using Visual Studio as my IDE and TFS as my source code repo.

  • How to structure an application that combines WCF and WPF

    - by CiaranG
    I'm in the process of learning how to use WCF (Windows Communication Foundation) to allow a client/server desktop application to communicate. The application's UI will be implemented using WPF, and we will probably use SQL Server for our database. What I'm struggling with, is understanding how to structure such an application. From what I've read, there are three components of a WCF application (which in the examples I've seen have existed as separate projects): A WCF service A WCF service host A WCF service client My question then, is - should these projects solely implement the functionality of sending/receiving data from the client/server? Would it make better sense this way? Would it make sense to create a separate WPF (Windows Presentation Foundation) project to implement the UI for the application? And so, when I need to send/receive data from the client/server, I could simply invoke the operations provided in the WCF projects that I have created? For anyone who has built similar applications previously, perhaps you could explain what worked best for you in terms of structuring your application? For example, if I create a user registration page. When the user clicks the 'Register' button, the client application will need to send the data to the server. In this case, could I just invoke the methods provided in the WCF projects to send the data? Also, what data structures worked best for you when sending/receiving data? My initial thought is sending/receiving XML containing the data. Is this an option that is easy to implement? I realise that answers to this question may well be a matter of opinion - unless there are specific best practices that I'm not aware of. Thank you

  • Designing a Content-Based ETL Process with .NET and SFDC

    - by Patrick
    As my firm makes the transition to using SFDC as our main operational system, we've spun together a couple of SFDC portals where we can post customer-specific documents to be viewed at will. As such, we've had the need for pseudo-ETL applications to be implemented that are able to extract metadata from the documents our analysts generate internally (most are industry-standard PDFs, XML, or MS Office formats) and place in networked "queue" folders. From there, our applications scoop of the queued documents and upload them to the appropriate SFDC CRM Content Library along with some select pieces of metadata. I've mostly used DbAmp to broker communication with SFDC (DbAmp is a Linked Server provider that allows you to use SQL conventions to interact with your SFDC Org data). I've been able to create [console] applications in C# that work pretty well, and they're usually structured something like this: static void Main() { // Load parameters from app.config. // Get documents from queue. var files = someInterface.GetFiles(someFilterOrRegexPattern); foreach (var file in files) { // Extract metadata from the file. // Validate some attributes of the file; add any validation errors to an in-memory // structure (e.g. List<ValidationErrors>). if (isValid) { var fileData = File.ReadAllBytes(file); // Upload using some wrapper for an ORM or DAL someInterface.Upload(fileData, meta.Param1, meta.Param2, ...); } else { // Bounce the file } } // Report any validation errors (via message bus or SMTP or some such). } And that's pretty much it. Most of the time I wrap all these operations in a "Worker" class that takes the needed interfaces as constructor parameters. This approach has worked reasonably well, but I just get this feeling in my gut that there's something awful about it and would love some feedback. Is writing an ETL process as a C# Console app a bad idea? I'm also wondering if there are some design patterns that would be useful in this scenario that I'm clearly overlooking. Thanks in advance!

  • Forking a dual licensed app: How to license on my end?

    - by TheLQ
    I forked a project that was dual licensed under the GPL and a commercial license. Since my code was open source and the GPL being what it is, I started by releasing my app under the GPL. But now I'm thinking about dual licensing the project and can't figure out what to do. Since I have copyright on a majority of the code (most of the code was either rewritten or new), can I just pick a commercial license or do I have to buy the upstream commercial license since I'm technically a "derivative" of the project?

  • Developing professionally for iOS, Android and web - an insight

    - by Scott Roberts
    This is not really a question on how to develop all three, I know various cross platform ways and so on. But I more want to know from developer standpoint how hard it is to basically develop iOS, Android and web apps? I am currently in my first job as a mobile/web developer. I have already developed my first iPhone/iPad app and now I have to develop the app for android because the web version I tried just didn't perform as well as needed and web databases just did not seem to make the cut. But I am not sure it's possible to be good at developing all 3 in terms of remembering all the api's etc. I wouldn't say I have an issue with the programming languages just how to use the api's for the various platforms. Also, all the other languages I look at, in my spare time, just feel like I am spreading myself to thin. Is it feasible for one person to be developing ios, android and web apps? Should I think about reducing it to iOS and web based apps? I develop everything by myself, so I have no one to discuss what the best solutions are for everything and I am just trying to workout as I go along. So any cross platform developers out there? Do companies have different teams for different platforms? Any insight would just help me get my head together. Hopefully this question makes sense.

  • Is there any reason to use "plain old data" classes?

    - by Michael
    In legacy code I occasionally see classes that are nothing but wrappers for data. something like: class Bottle { int height; int diameter; Cap capType; getters/setters, maybe a constructor } My understanding of OO is that classes are structures for data and the methods of operating on that data. This seems to preclude objects of this type. To me they are nothing more than structs and kind of defeat the purpose of OO. I don't think it's necessarily evil, though it may be a code smell. Is there a case where such objects would be necessary? If this is used often, does it make the design suspect?

  • Can I use access used by Visual Basic for building a database [on hold]

    - by user3413537
    I am the only programmer where I work (summer job) and I am a student with only a few years of programming experience. So I was asked to build a database and I am very excited about this project because hopefully I can learn a lot from this. Using this database my manager is supposed to be able to assign work (dealing with businesses) to different people within the company using an interface (all workers have a shared drive). When workers are done with that paperwork related to the business, they can check off that its done, add comments at the bottom of the interface, and then move on to the next business. The only experience I've had with databases is some querying with SQL, and I've built GUI interfaces with JAVA. The information on the interface will be populated from Excel so workers know what businesses they are dealing with. I've done some research and I believe the best way to build this would be building a GUI using Microsoft Visual Studio (Visual Basic) first, then figuring out a way to populate the Interface from Excel. Also because the data is pretty straight forward and not complicated I will be using MS Access to store and track the database. I know this won't be easy, but for all you geniuses out there, is this on the right path? Thanks.

  • Single python file distribution: module or package?

    - by DanielSank
    Suppose I have a useful python function or class (or whatever) called useful_thing which exists in a single file. There are essentialy two ways to organize the source tree. The first way uses a single module: - setup.py - README.rst - ...etc... - foo.py where useful_thing is defined in foo.py. The second strategy is to make a package: - setup.py - README.rst - ...etc... - foo |-module.py |-__init__.py where useful_thing is defined in module.py. In the package case __init__.py would look like this from foo.module import useful_thing so that in both cases you can do from foo import useful_thing. Question: Which way is preferred, and why? EDIT: Since user gnat says this question is poorly formed, I'll add that the official python packaging tutorial does not seem to comment on which of the methods described above is the preferred one. I am explicitly not giving my personal list of pros and cons because I'm interested in whether there is a community preferred method, not generating a discussion of pros/cons :)

  • Is it a good idea to put all assembly: WebResource in the same cs file?

    - by Guilherme J Santos
    I have a .NET library, with some WebControls. These webControls have Embed Resources. And we declare them like it, in all webcontrols for each cs file: Something like this: [assembly: WebResource("IO.Css.MyCSS.css", "text/css")] namespace MyNamespace.MyClass { [ParseChildren(true)] [PersistChildren(false)] [Designer(typeof(MyNamespace.MyClassDesigner))] public class QuickTip : Control, INamingContainer { //My code... } } Would it be a good idea to create a cs file and include all WebResource declarations there? Example a cs file with just: [assembly: WebResource("IO.Css.MyCSS.css", "text/css")] [assembly: WebResource("IO.Image.MyImage.png", "image/png")] //And many other WebResources of all WebControls of the Assembly

  • conventions for friend methods in Perl

    - by xenoterracide
    Perl doesn't support a friend relationship between objects, nor does it support private or protected methods. What is usually done for private methods is to prefix the name with an underscore. I occasionally have methods that I think of as friend methods. Meaning that I expect them to be used by a specific object, or an object with a specific responsibility, but I'm not sure if I should make that method public (meaning foo ) or private ( _foo ) or if there's a better convention? is there a convention for friend methods?

  • White box testing with Google Test

    - by Daemin
    I've been trying out using GoogleTest for my C++ hobby project, and I need to test the internals of a component (hence white box testing). At my previous work we just made the test classes friends of the class being tested. But with Google Test that doesn't work as each test is given its own unique class, derived from the fixture class if specified, and friend-ness doesn't transfer to derived classes. Initially I created a test proxy class that is friends with the tested class. It contains a pointer to an instance of the tested class and provides methods for the required, but hidden, members. This worked for a simple class, but now I'm up to testing a tree class with an internal private node class, of which I need to access and mess with. I'm just wondering if anyone using the GoogleTest library has done any white box testing and if they have any hints or helpful constructs that would make this easier. Ok, I've found the FRIEND_TEST macro defined in the documentation, as well as some hints on how to test private code in the advanced guide. But apart from having a huge amount of friend declerations (i.e. one FRIEND_TEST for each test), is there an easier idion to use, or should I abandon using GoogleTest and move to a different test framework?

  • Is there a name for a testing method where you compare a set of very different designs?

    - by DVK
    "A/B testing" is defined as "a method of marketing testing by which a baseline control sample is compared to a variety of single-variable test samples in order to improve response rates". The point here, of course, is to know which small single-variable changes are more optimal, with the goal of finding the local optimum. However, one can also envision a somewhat related but different scenario for testing the response rate of major re-designs: take a baseline control design, take one or more completely different designs, and run test samples on those redesigns to compare response rates. As a practical but contrived example, imagine testing a set of designs for the same website, one being minimalist "googly" design, one being cluttered "Amazony" design, and one being an artsy "designy" design (e.g. maximum use of design elements unlike Google but minimal simultaneously presented information, like Google but unlike Amazon) Is there an official name for such testing? It's definitely not A/B testing, since the main component of it (finding local optimum by testing single-variable small changes that can be attributed to response shift) is not present. This is more about trying to compare a set of local optimums, and compare to see which one works better as a global optimum. It's not a multivriable, A/B/N or any other such testing since you don't really have specific variables that can be attributed, just different designs.

  • How far to go with Domain Driven Design?

    - by synti
    I've read a little about domain driven design and the usage of a rich domain model, as described by Martin Fowler, and I've decided to put it in practice in a personal project, instead of using transaction scripts. Everything went fine until UI implementation started. The thing is some views will use rich components that are backed up by unusual models and, thus, I must transform the domain model into what is used by those components. And that transformation is specially "complex" in the view-to-domain portion, up to the point that some business logic is involved. Wich brings me to the questioning: where should I do these adaptations? So far I've got the following conclusions: Doing it in the presentation layer is good because, well, if that layer imposes restrictions in it's model, then it should be the one to handle them. But it's bad because there'll be some business leakage. If I do it on the services objects (controllers, actions, whatever), then it'd be good because there won't be any change to the domain API just because of presentation layer, but it's bad because then I'd have transaction scripts, wich is not the intended design. Finally, if I do it on the domain model, there'd be no leakage of business logic at all. But in the future I could expect an explosion of the API into a series of methods designed just to handle that view-model <- domain-model adaptation. I hope I could make myself clear on this.

  • Reverse horizontal and vertical for a HTML table

    - by porton
    There is a two-dimensional array describing a HTML table. Each element of the array consists of: the cell content rowspan colspan Every row of this two dimensional array corresponds to <td> cells of a <tr> of the table which my software should generate. I need to "reverse" the array (interchange vertical and horizontal direction). Insofar I considered algorithm based on this idea: make a rectangular matrix of the size of the table and store in every element of this matrix the corresponding index of the element of the above mentioned array. (Note that two elements of the matrix may be identical due rowspan/colspan.) Then I could use this matrix to calculate rowspan/colspan for the inverted table. But this idea seems bad for me. Any other algorithms? Note that I program in PHP.

  • Computer Science Programming Certificate vs. Computer Science Degree?

    - by Jess
    I'm kind of in a tough spot. My current living conditions require that I work a full-time job while attending school. I've attended a UC in the past but had to withdraw my junior year due to financial issues at home. I currently work an entry-level IT corp job but I'm looking to further my salary/skills by getting a degree, or a programming certificate like this one: http://www.lavc.edu/voced1/CSITCertCSP/CSITCertFrameCSP.htm Herein lies the problem. I prefer getting a CS degree from an accredited university but I looked at the schedules for classes and it is impossible to work around my current 40/hr work week. There are random morning classes, with the occasional evening class, but the times get even more construed as I move my way up to the upper divisions. So what I guess I'm trying to get at is, can anyone lay out the pros and cons of obtaining a certificate vs. the degree (besides obvious points like the latter being 100x better)? I'm aware that having a degree is always going to be a better route, but...is the programming certificate useless? Should I not even bother?
