  • Should a poll framework be closed sourced

    - by samquo
    I was having a chat with a coworker who is working on a polling app and framework. He was asking technical questions and I suggested he open source the application to get more quality opinions from developers who are interested in this problem and are willing to give it heavy though. He has a different point of view which I think is still valid so I want to open this question for discussion here. He says he believes something like a polling framework should not be open sourced because it will reduce its security and validity as people reveal loopholes through which they can cheat. Can't say I completely disagree. I see a somewhat valid point there, but I always believed that solutions by a group of people are almost always better than a solution thought by a single person asking a small number of coworkers, no matter how smart that person is. Again I'm willing to accept that maybe some types of applications are different. Does anyone have an argument in his favor? I'd really like to present your responses to him.

  • My Rhythmbox plugin can't meet the Ubuntu Software Center "my-app" requirements

    - by allquixotic
    At http://developer.ubuntu.com/publish/my-apps-packages/ the following technical requirements are cited: Technical requirements In order for your application to be distributed in the Software Centre it must: Be in one, self-contained directory when installed Be able to be installed into the /opt/ directory (*) Be executable by all users from the /opt/ directory (**) Write all configuration settings to ~/.config/ (This can be one file or a directory containing multiple configuration files) A Rhythmbox plugin cannot satisfy any of these requirements. Rhythmbox has compiled-in locations where it looks for installed plugins. So, is there no way for me to publish my app in Ubuntu Software Center? Would it have to go into Universe repository (which would require tremendously more work and political maneuvering to get it accepted)? I already have all the Debian package infrastructure built for it, so I have made a PPA for it.

  • Anyone been successful changing their career without having to start over from scratch?

    - by Awaken
    I posted a similar question on careeroverflow, but stackoverflow is just way more active and has way more users, so hopefully someone out there can help answer. I am currently an embedded developer in the defense/aerospace world for a big company. While I like the benefits and the pay, it just isn't keeping me happy. The Paul Graham article: How To Do What You Love really struck home. The problem I face are my golden handcuffs. When I look at jobs out there, they all want 5+ years experience in that language with expertise in framework/tool/server A,B,C, etc... I have worked in C and C++ on the job (in a real-time embedded environment) with some small things in C# and Java. I'm learning Ruby now to expand my knowledge, but I don't consider myself an expert in anything right now. I'd love to work on desktop applications or web apps. Is it possible for someone like me to make the switch without going back to the start line? I'd love to leave the huge bureaucracy and work with some great developers. I'd be willing to work late and take a modest pay cut, but that isn't so clear just from a resume. For those that have altered their career path, how did you do it? For those people who are in charge of hiring, what can I do to help myself?

  • .aspx websites: Is it built using web forms?

    - by Lazeera
    I visit many website which I think is built using ASP.NET web forms because of the extension (.aspx). When I view source of these website I see at least one or two something like: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"> or wvcD4NCjxwPtin2YTZh9iv2YrYqSDYp9mE2KvYp9mG2YrYqSDZh9mKINit2..... However, yesterday I visited two sites on is the 'ASP.NET forums - http://forums.asp.net' and the other is 'POF'. The extension of these sites is still (.aspx) but when I view the source of these site I could not find any <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"> nor wvcD4NCjxwPtin2YTZh9iv2YrYqSDYp9mE2KvYp9mG2YrYqSDZh9mKINit2..... Now, I would like to know how those sites use ASP.NET Web Forms and their final HTML output is still clean?

  • Do we need to adopt a black-box asset our project is inheriting from its predecessor?

    - by Tom Anderson
    Our client has an eCommerce site which was developed by an in-house team, and is now showing its age. I work for a firm brought in as external contractors to build a replacement. Part of the current site is a Flash viewer applet which displays media about the product - zoom-able images, 360-degree views, movies, and so on. We need to show the same media the current site does, so we are simply reusing the viewer. The viewer is embedded on a page in the usual way, and told what media to show by means of an XML file it loads from our server, which is pretty simple for us to generate. We've got this working; it was pretty straightforward. But what else do we need to do? The thing is, as far as we're concerned, the viewer is a binary blob which is served from the client's content-distribution network. We embed it, feed it some XML, and it does its job, but we have no power over its internals. It's completely opaque to us - a black box. We can use it to do what it does, but we can't change it, so if we ever need to do something different, we're stuffed. We're building this site for the client, and when we're done, we'll hand it over for them to maintain. We won't be doing the maintenance ourselves. There's a small team within the client who are working as part of our team, and who will be the ones doing the maintenance. That team only includes one person from the team that built the old site, and it's not someone who knows the image viewer. The people who do know the image viewer are not slated to join our team when our system replaces theirs - they'll be moved to other projects. The documentation on the viewer is extremely thin, and as far as i know doesn't cover the internals at all. My worry is that if someone doesn't take some positive action, all knowledge of the internal workings of the viewer - even down to where the source code for it is - will be lost. It's possible it already has been. Is this something to worry about? If so, whose job is it to worry about it? What should they do about it once they've got worried?

  • What is your strategy for converting RC builds into retail?

    - by Matthew PK
    We're trying to implement a strategy for how we transition our builds from RC to released retail code. When we label a build as a release candidate, we send it to QA for regression. If they approve it, that RC then becomes our released retail code. I liked the idea of "obvious" labeling of versions so that a user knows whether they have a beta or an RC or retail code... where you would have some obvious watermark in non-retail code (think Windows 7 where the RC or non-genuine builds watermark in the bottom right). ... but it seemed strange to us to manipulate the project (to remove the watermark) once it passed regression. If QA certified version a.b.c.d then our retail code should be that same version, not a.b.c.d+1 what strategies have you employed to clearly label non-release software versions without incrementing your build to disable the watermarks in your retail code? One idea I've considered is writing your build to look for a signed file in the installer archive... non-release code wouldn't include this file and so the app would know to display a watermark. But even this seems like QA is then working with non-release code. Ideas?

  • The layout page "~/Views/Shared/_Layout.cshtml" could not be found

    - by Rei Brazilva
    I got this error and I can't figure out what is going on. I am positive the _layout.cshtml resides in the shared folder and for the sake of trying things out, I moved to the Home folder and it then told that the Views/Home/_Layout.cshtml couldn't be found there either. So now I'm thinking the problem is in the call for this file for some reason. I'm not going to pretend I know ASP.NET MVC4, so please when you answer, explain it as you would to someone who is not familiar with the system at all. Believe it or not, this error came from tutorial #1 ha ha Here's the code to show that I did code it right: @{ ViewBag.Title = "Home Page"; Layout = "~/Views/Shared/_Layout.cshtml"; } And here is a picture of the location p.s. I did my research, Google has nothing and there is another question here but it was asked on 2008 with MVC3 which is completely different I am running ASP.NET MVC4 on Azure Thanks

  • What kind of an IT or programming job can a college student get part time?

    - by Alex Foster
    I'm a college student with a full load of classes and i need some extra money to cover some of my expenses. I love anything and everything to do with computers. I don't know how to program but have build computers before and know how windows works. I would call myself a power user. My question is, what kind of a job can someone like me get with effort? If there are some more skills that i can pick up that would benefit in getting the foot in the door i would love to hear about them. The only limitation i have is that i can't work very late in the evening most days due to classes. But usually in the morning my time is available for work. I will appreciate all answers i receive. Thank you for your help.

  • ecommerce options for 5-6 products

    - by Calum
    Hi, We're looking to develop a simple e-commerce solution to sell 5-6 products. We'd rather not have to use PayPal's buttons (buy it now!) if there's an existing alternative, but would also for budget/time constraints don't want to roll our own. Are there any small, basic ecommerce solutions available that would allow this? I did look at Foxy Cart but the monthly fee was a bit of a turn off. (I must sound extremely fussy I'm aware!) Something like Zen would just be overkill for our needs. Thanks for any suggestions.

  • Storing application preferences and data

    - by Rudi Strydom
    I am looking at creating some Ubuntu applications, but finding good resoures are hard. I am using the quickly toolkit, but would really like some more insight. How does one normally store application preferences and settings in Linux / Ubuntu. Is it as simple as creating a XML file and saving the information and then reading from said file on application bootstrap? If someone can point me in a direction it would be greatly appreciated.

  • Graduate expectations versus reality

    - by Bobby Tables
    When choosing what we want to study, and do with our careers and lives, we all have some expectations of what it is going to be like. Now that I've been in the industry for almost a decade, I've been reflecting a bit on what I thought (back when I was studying Computer Science) programming working life was going to be like, and how it's actually turning out to be. My two biggest shocks (or should I say, broken expectations) by far are the sheer amount of maintenance work involved in software, and the overall lack of professionalism: Maintenance: At uni, we were all told that the majority of software work is maintenance of existing systems. So I knew to expect this in the abstract. But I never imagined exactly how overwhelming this would turn out to be. Perhaps it's something I mentally glazed over, and hoped I'd be building cool new stuff from scratch a lot more. But it really is the case that most jobs are overwhelmingly maintenance, bug fixing, and support oriented. Lack of professionalism: At uni, I always had the impression that commercial software work is very process-oriented and stringently engineered. I had images of ISO processes, reams of technical documentation, every feature and bug being strictly documented, and a generally professional environment. It came as a huge shock to realise that most software companies operate no differently to a team of students working on a large semester-long project. And I've worked in both the small agile hack shop, and the medium sized corporate enterprise. While I wouldn't say that it's always been outright "unprofessional", it definitely feels like the software industry (on the whole) is far from the strong engineering discipline that I expected it to be. Has anyone else had similar experiences to this? What are the ways in which your expectations of what our profession would be like were different to the reality?

  • If PHP websites represnt 70% of websites in my country then should I learn it?

    - by Fadi Tiwari
    In my country most of the sites are built using PHP and MySQL. Half of those sites use vbulletin and Wordpress. When it comes to companies, ministries and universities they use ASP.NET. I am not sure what should I learn to get more money as freelacer? Should I learn ASP.NET and focus my area to build companies and universities' sites? (And the question if they will know me one day and ask me to build any of their sites or not?) Or should I learn PHP and focus my business on people's sites and maybe some small formal sites? Which option will give me more money?

  • Java based portal framework

    - by Jatin
    We have an application that needs to be built and are looking for some Java based portal framework. In last few days I have gone through over 10 different open source option LiveRay, JetSpeed2, GateIn etc. But they are all too complex to be judged so quickly. Can anyone suggest some framework which is ease to use but has the functionality to handle complex situations. Most importantly, the portlets will run flash/HTML5 contant. Thanks.

  • Advancing my Embedded knowledge.....with a CS degree.

    - by Mercfh
    So I graduated last December with a B.S. in Computer Science, in a pretty good well known engineering college. However towards the end I realized that I actually like Assembly/Lower level C programming more than I actually enjoy higher level abstracted OO stuff. (Like I Programmed my own Device Drivers for USB stuff in Linux, stuff like that) But.....I mean we really didn't concentrate much on that in college, perhaps an EE/CE degree would've been better, but I knew the classes......and things weren't THAT much different. I've messed around with Atmel AVR's/Arduino stuff (Mostly robotics) and Linux Kernals/Device Drivers. but I really want to enhance my skills and maybe one day get a job doing embedded stuff. (I have a job now, it's An entry level software dev/tester job, it's a good job but not exactly what my passion lies in) (Im pretty good with C and certain ASM's for specific microcontrollers) Is this even possible with a CS degree? or am I screwed? (since technically my degree usually doesn't involve much embedded stuff) If Im NOT screwed then what should I be studying/learning? How would I even go about it........ I guess I could eventually say "Experienced with XXXX Microcontrollers/ASM/etc...." but still, it wouldn't be the same as having a CE/EE degree. Also....going back to college isn't an option. just fyi. edit: Any book recommendations for "getting used to this stuff" I have ARM System-on-Chip Architecture (2nd edition) it's good.....for ARM stuff lol

  • Is it possible to use Python with the Ubuntu SDK?

    - by Zignd
    David Planella wrote in his answer to a question I posted that: ...the recommended way to develop apps for Ubuntu is the Ubuntu SDK. So I installed it, but looks like the supported programming language is C++. Does it mean I will need to know C++ to develop a new application for Ubuntu? Is C++ the recommended programming language for Ubuntu application now? What about Python, I started learning it hoping to develop applications for Ubuntu.

  • Enterprise Service Bus (ESB): Important architectural piece to a SOA or is it just vendor hype?

    Is an Enterprise Service Bus (ESB) an important architectural piece to a Service-Oriented Architecture (SOA), or is it just vendor hype in order to sell a particular product such as SOA-in-a-box? According to IBM.com, an ESB is a flexible connectivity infrastructure for integrating applications and services; it offers a flexible and manageable approach to service-oriented architecture implementation. With this being said, it is my personal belief that ESBs are an important architectural piece to any SOA. Additionally, generic design patterns have been created around the integration of web services in to ESB regardless of any vendor. ESB design patterns, according to Philip Hartman, can be classified in to the following categories: Interaction Patterns: Enable service interaction points to send and/or receive messages from the bus Mediation Patterns: Enable the altering of message exchanges Deployment Patterns: Support solution deployment into a federated infrastructure Examples of Interaction Patterns: One-Way Message Synchronous Interaction Asynchronous Interaction Asynchronous Interaction with Timeout Asynchronous Interaction with a Notification Timer One Request, Multiple Responses One Request, One of Two Possible Responses One Request, a Mandatory Response, and an Optional Response Partial Processing Multiple Application Interactions Benefits of the Mediation Pattern: Mediator promotes loose coupling by keeping objects from referring to each other explicitly, and it lets you vary their interaction independently Design an intermediary to decouple many peers Promote the many-to-many relationships between interacting peers to “full object status” Examples of Interaction Patterns: Global ESB: Services share a single namespace and all service providers are visible to every service requester across an entire network Directly Connected ESB: Global service registry that enables independent ESB installations to be visible Brokered ESB: Bridges services that are reluctant to expose requesters or providers to ESBs in other domains Federated ESB: Service consumers and providers connect to the master or to a dependent ESB to access services throughout the network References: Mediator Design Pattern.

  • Is client side JavaScript capable of ~replicating the Node.JS module loading system?

    - by jt0dd
    I like the Node.JS style of JavaScript, where I can write all of my functionalities into smaller files and then require those neatly from within my code. I'm even thinking about trying to write a framework to mimic that behavior in client-side JS. My goal would be to implement the module loading system as accurately as possible - See Module docs. For require(), I can use things detailed in answers to this question, most notably JQuery's $.getScript(). It seems to me that other aspects of the module loading system should be possible as well. So I'm asking more experienced programmers here first, before I waist my time: Is there something that I'm missing that's going to cause such an attempt to fail miserably, or can this be successfully done?

  • How to add a holding page in front of a domain

    - by Jason Bradberry
    I have set up a holding page to announce a new version of a website coming soon. I wanted people to still be able to access the original site, so my approach was to place the holding page in the root folder on the server, and move the original site to a subfolder and link to it from the holding page. However, on testing this setup it appears to have hurt the SEO placing of the website. Is there a better approach to this? I'm a bit stumped as I want both to share the same URL.

  • Are XML Comments Necessary Documentation?

    - by Bob Horn
    I used to be a fan of requiring XML comments for documentation. I've since changed my mind for two main reasons: Like good code, methods should be self-explanatory. In practice, most XML comments are useless noise that provide no additional value. Many times we simply use GhostDoc to generate generic comments, and this is what I mean by useless noise: /// <summary> /// Gets or sets the unit of measure. /// </summary> /// <value> /// The unit of measure. /// </value> public string UnitOfMeasure { get; set; } To me, that's obvious. Having said that, if there were special instructions to include, then we should absolutely use XML comments. I like this excerpt from this article: Sometimes, you will need to write comments. But, it should be the exception not the rule. Comments should only be used when they are expressing something that cannot be expressed in code. If you want to write elegant code, strive to eliminate comments and instead write self-documenting code. Am I wrong to think we should only be using XML comments when the code isn't enough to explain itself on its own? I believe this is a good example where XML comments make pretty code look ugly. It takes a class like this... public class RawMaterialLabel : EntityBase { public long Id { get; set; } public string ManufacturerId { get; set; } public string PartNumber { get; set; } public string Quantity { get; set; } public string UnitOfMeasure { get; set; } public string LotNumber { get; set; } public string SublotNumber { get; set; } public int LabelSerialNumber { get; set; } public string PurchaseOrderNumber { get; set; } public string PurchaseOrderLineNumber { get; set; } public DateTime ManufacturingDate { get; set; } public string LastModifiedUser { get; set; } public DateTime LastModifiedTime { get; set; } public Binary VersionNumber { get; set; } public ICollection<LotEquipmentScan> LotEquipmentScans { get; private set; } } ... And turns it into this: /// <summary> /// Container for properties of a raw material label /// </summary> public class RawMaterialLabel : EntityBase { /// <summary> /// Gets or sets the id. /// </summary> /// <value> /// The id. /// </value> public long Id { get; set; } /// <summary> /// Gets or sets the manufacturer id. /// </summary> /// <value> /// The manufacturer id. /// </value> public string ManufacturerId { get; set; } /// <summary> /// Gets or sets the part number. /// </summary> /// <value> /// The part number. /// </value> public string PartNumber { get; set; } /// <summary> /// Gets or sets the quantity. /// </summary> /// <value> /// The quantity. /// </value> public string Quantity { get; set; } /// <summary> /// Gets or sets the unit of measure. /// </summary> /// <value> /// The unit of measure. /// </value> public string UnitOfMeasure { get; set; } /// <summary> /// Gets or sets the lot number. /// </summary> /// <value> /// The lot number. /// </value> public string LotNumber { get; set; } /// <summary> /// Gets or sets the sublot number. /// </summary> /// <value> /// The sublot number. /// </value> public string SublotNumber { get; set; } /// <summary> /// Gets or sets the label serial number. /// </summary> /// <value> /// The label serial number. /// </value> public int LabelSerialNumber { get; set; } /// <summary> /// Gets or sets the purchase order number. /// </summary> /// <value> /// The purchase order number. /// </value> public string PurchaseOrderNumber { get; set; } /// <summary> /// Gets or sets the purchase order line number. /// </summary> /// <value> /// The purchase order line number. /// </value> public string PurchaseOrderLineNumber { get; set; } /// <summary> /// Gets or sets the manufacturing date. /// </summary> /// <value> /// The manufacturing date. /// </value> public DateTime ManufacturingDate { get; set; } /// <summary> /// Gets or sets the last modified user. /// </summary> /// <value> /// The last modified user. /// </value> public string LastModifiedUser { get; set; } /// <summary> /// Gets or sets the last modified time. /// </summary> /// <value> /// The last modified time. /// </value> public DateTime LastModifiedTime { get; set; } /// <summary> /// Gets or sets the version number. /// </summary> /// <value> /// The version number. /// </value> public Binary VersionNumber { get; set; } /// <summary> /// Gets the lot equipment scans. /// </summary> /// <value> /// The lot equipment scans. /// </value> public ICollection<LotEquipmentScan> LotEquipmentScans { get; private set; } }

  • Why don't I have a loop error with these redirects?

    - by byronyasgur
    I know this may seem a bit of a question in reverse, but I actually don't seem to have a problem I just want to make sure before I proceed. I have 2 domains domain1.com and domain2.com and a directory my_directory at domain2.com. I have domain2.com setup as an "add on domain" in the cpanel account of domain1.com so that when I go to domain2.com I am taken to domain1.com/my_directory but the browser shows domain2.com in the addressbar so it looks and acts like and is a separate site. However when people browse to domain1.com/directory I want the address bar to show domain2.com not domain1.com/directory. So I put a redirect in the htaccess file to redirect domain1.com/directory to domain2.com and it works perfectly, but I think it shouldnt and I'm worried I've done something wrong. My question is this: domain2.com was already redirected to domain1.com/directory in the first place (I see the redirect in my cpanel under addon domains) so by adding the second redirect in the htaccess file I should be creating a loop! Could somebody please set my mind at rest and show me why not?

  • What do you do about content when someone asks you to build a website

    - by Jon
    I am an experienced asp.net developer and asp.net mvc and I have my own CMS that I have written but starting to think there should be another approach. When someone asks you to develop them a website how do you develop it so that they can add pictures,slideshows, content, news items, diary events. On a side note do you give them a design for the home page and inner page and thats it. I'm just thinking if they turn around and say 6 months down the line I want a jquery slideshow on the right hand side of this page how do you or CMS's handle it?

  • The next step for a graduate?

    - by Michael Hobbs
    I will complete my degree in Computer Science in July of 2013 however I will have two years of military service left. I would like to get some hands on C#/C++ programming experience in the mean time. I have been looking around the web at all the open source project that are out there. There are literally 10's of thousands. How would you go about picking one that is: A) good for a graduate level programmer B) will probably go somewhere, and C) are willing to take a novice under their wing. I would even be happy to work for a company for free, remotely as a debugger, tester, or what have you. As a side note would prefer to stick in the C# realm but understand I need to branch out at the same time.

  • Why isn't Stripes popular, even though it's an awesome web framework?

    - by Mr.Chowdary
    I'm new to Stripes. I worked on MVC frameworks like Struts 1.x and 2.x. When I started learning, its features are awesome and very lightweight; it has in-depth validations and offers easy integration with other frameworks too. There are no configurations and everything is simplified with annotations. I don't understand why Stripes is not popular compared with other Java web frameworks like Struts or JSF? I didn't find any drawbacks in Stripes. Any ideas why?
