  • Application use on website

    - by Palmer
    Is there a good way to run a C# application on clientside in lieu of JavaScript? I have done some front end work with JavaScript and backend C# for web developing at an old job, but I am interested in hosting a website myself soon. I have a C# application I would like to be open source, but before people care to download I'd like them to be able to use it. At its basic level it's a simple text editor, but there's much more to it in the nitty gritty. I could write it in JavaScript, but it would require me to keep documentation and up to date changes on JavaScript and C# in that case. I was thinking of creating an AJAX panel and somehow loading my winform application into a frame, but I don't know how or what words to google because I've never done it before except AJAX.

  • GWT (Google Web Toolkit) Designer not working on Ubuntu 12.10

    - by Marian Lux
    The GWT Desinger is not working on Ubuntu 12.10. It worked on Ubuntu 12.04. I installed the Eclipse Plugin as described on the GWT Homepate If I want to open the Design-View (for an xml-GWT-File), Eclipse crashes (prompt closing of the application). I found this two workarounds for which are for 12.04 (but on 12.04 i did not need this to get it working - it worked out of the box for me). I tried them on my 12.10 Ubuntu but they are not working. But I have to say that I can't find the "Use WebKit for rendering GWT UI (if available)"-Flag. What can I do to get the GWT Designer working? I tested it successfully again on a 12.04 Ubuntu VMware image. If I don't get a solution, I have to downgrade my Ubuntu to 12.04 again.

  • How can you predict the time it will take for two processes in two different machines in a cluster to communicate?

    - by Dokkat
    I am trying to develop a computing application which needs a lot of memory (500gb). Buying a single machine for that is overly expensive. I can, though, buy ~100 small instances on Digital Ocean or similar, divide the memory in blocks and use TCP to emulate shared memory between the instances. Now, my question is: how can I measure/predict the time it will take for two processes in two different machines like that to share information, in comparison to IPC and shared memory? Are there rules of thumb? I don't want exact values, but knowing more or less how much faster one is would be very helpful in visualising the feasibility of this approach.

  • How do you stop yourself from programming?

    - by dan
    Lately I've started earning enough off my software to not have to do consulting to support myself. So I work full time designing and writing my own software products. The problem is that there are no boundaries between my work and my life any more. When I mostly did consulting, I was weary enough of work at the end of the workday to go home and do other things. But now, I sit down to program in the morning, and before I know it it's 11pm and I'm still writing software and not bored or tired at all. I have to force myself to go to sleep. I feel happy and fulfilled, but objectively, I know I need more balance and variety in my life. Any tips or suggestions on how to pull yourself away from the console?

  • Need advice for approach for a web-based app that loads excel worksheet but exposes only the charts

    - by John
    I'm looking for suggestions on the Visual Studio approach to take for a web application that is in the conceptual stage. My environment has a lot of tools: Windows Server 2008 R2 Standard 64bit Visual Studio 2010 Professional Edition Sharepoint 2010 Server Enterprise Edition SQL Server 2008 R2 Office 2010 Professional I know I will need this app to retrieve data from a database (or a web service - not sure exactly at this point). The data needs to be placed in an Excel workbook dynamically. The app will need to have a nice user interface (standard web controls - perhaps with some Javascript effects). The Excel ribbon and worksheet grid will need to be hidden. Some web control(s) will cause the Excel chart(s) to be rendered. I am thinking this sounds like Visual Studio Tools for Office (VSTO) so as to leverage .Net and hide Excel. Can you offer suggestions regarding: One ASP.Net Web App Project One Class Library Project for Excel or perhaps which one of the several different Excel 2010 project types (addin, template, document) Would Excel Services for Sharepoint be useful (or required) ? I am feeling a little overwhelmed with so many choices at this early stage of conceptualizing the app. Can you suggest some ideas for this sort of thing? Also, I am a bit more experienced with C# but I've read VB.Net is better for work with the Excel object model. What are general advises with regard to tool choice and overall approach tradeoffs?

  • Referencing external javascript vs. hosting my own copy

    - by Mr. Jefferson
    Say I have a web app that uses jQuery. Is it better practice to host the necessary javascript files on my own servers along with my website files, or to reference them on jQuery's CDN (example: http://code.jquery.com/jquery-1.7.1.min.js)? I can see pros for both sides: If it's on my servers, that's one less external dependency; if jQuery went down or changed their hosting structure or something like that, then my app breaks. But I feel like that won't happen often; there must be lots of small-time sites doing this, and the jQuery team will want to avoid breaking them. If it's on my servers, that's one less external reference that someone could call a security issue If it's referenced externally, then I don't have to worry about the bandwidth to serve the files (though I know it's not that much). If it's referenced externally and I'm deploying this web site to lots of servers that need to have their own copies of all the files, then it's one less file I have to remember to copy/update.

  • Will a programming professional certificate from a university enhance my resume/prospect for being hired?

    - by Cliff
    Hi. I am a junior in Software Engineering. I'm planning to take up an Online Certification in web programming or .NET programming from the University of Illinois through O'Reilly (see link) to keep busy this summer. Will that help me get a great job? I've heard some say that certifications will give you a cutting edge. I've heard others say that it doesn't really matter. What do you think? Thanks so much for you advice and point of view.

  • How quickly does the Java language get outdated?

    - by Dummy Derp
    I started learning Java recently. I started learning it using books that I picked up from the library, some that I bought, and here and there from Java documentation. The book that I use for Java was published in the year 2011. In 2012, Java8 will be released followed by Java9 in the year 2013. The questions are: How do I keep myself updated about developments in Java without having to buy a tome for Java8 and/or Java9 Is a book published in 2008 an outdated book for studying JSP and Servelets? I'm talking about Head First Servlets and JSP

  • Should I concentrate on writing code for money or my studies while in college?

    - by A-Cube
    I am college student of Software Engineering. My worries are that while I am concentrating on my studies, my peers are getting down with the code (e.g. HTML, ASP, PHP, etc) to earn money. Should I be worried that I am not doing coding like them? I was asked to be Microsoft Student Partner but I refused because the person what was doing before me told it was just arranging events. Nothing as such like getting with Microsoft and coding. Should I be writing code and earning money as I still am in 4th semester? I only have C++ as learning language in college. Will my job count on these projects that I do, or should I concentrate on studies for now to get maximum benefit?

  • Large enterprise application - clients wish to use duplicate e-mails addresses?

    - by Alex Key
    I'd like to know people's opinions, reactions to clients and technical work arounds (if applicable), to the issue of an enterprise application where a client wishes to use duplicate e-mail addresses? To clarify, when I say duplicate e-mail addresses I mean within the same client system, having multiple users that have the same e-mail address. So not just using generic e-mail addresses but using the e-mail address of another user. e.g. Bob Jenkins: [email protected] James Jeffery: [email protected] Context To give this some further context, in the e-learning sector it is common that although all staff in an organisation must complete e-learning - they may not have their own e-mail address so they choose to use their managers e-mail address. Albeit against good practice in public sites... it's a requirement we've over and over again where an organisation is split between office based staff and perhaps e.g. staff in a warehouse. Where problem lies Mr Steak, good point, the problem lies in password resets and perhaps in situations where semi-personal information could be sent (not confidential enough to worry about the insecurities of email). Perhaps reminders for specific system actions, which would be confusing for the unintended party to see (if perhaps misreading the e-mail's intended recipient) Possible solutions System knowing the difference between a "for the attention of" and direct to the person e-mails, including this in the body text. Using alternative communication such as SMS Simply not having e-mails sent to people who are not the intended recipient. Providing an e-mail service ourselfs (not really viable for a corporate IT dept) Thoughts?

  • Language-independent sources on collision detection

    - by Phazyck
    While making a Pong clone with a friend, we had to implement some collision detection. For research purposes, my friend dug up a book called "AdvancED Game Design with Flash" by Rex Van Der Spuy. This book was clearly targeted at implementing collision detection in ActionScript, and I also have some problems with how the concepts are presented, e.g. presenting one method as better than another, without explaining that decision. Can anyone recommend some good material on collision detection? I'd prefer it if kept the implementation details as language-independent as possible, e.g. by implementing the concepts in pseudo-code. Language-specific materials are not completely unwelcome though, though I'd prefer those to be in either Java, C#, F# or Python or similar languages, as those are the ones I'm most familiar with. :-) Lastly, is there perhaps widely known and used book on collision detection that most people should know about, like a 'the book on collision detection'?

  • What are some efficient ways to set up my environment when working on a remote site?

    - by Prefix
    Hello fellow Programmers, I am still a relatively new programmer and have recently gotten my first on-campus programming position. I am the sole dev responsible for 8 domains as well as 3 small sized PHP web apps. The campus has its web environment divided into staging and live servers -- we develop on the staging via SFTP and then push the updates to the live server through a web GUI. I use Sublime Text 2 and the Sublime SFTP plugin currently for all my dev work (its my preferred editor). If I am just making an edit to a page I'll open that individual file via the ftp browser. If I am working on the PHP web app projects, I have the app directory mapped to a local folder so that when I save locally the file is auto-uploaded through Sublime SFTP. I feel like this workflow is slow and sub-optimal. How can I improve my workflow for working with remote content? I'd love to set up a local environment on my machine as that would eliminate the constant SFTP upload/download, but as I said there are many sites and the space required for a local copy of the entire domain would be quite large and complex; not to mention keeping it updated with whatever the latest on the staging server is would be a nightmare. Anyone know how I can improve my general web dev workflow from what I've described? I'd really like to cut out constantly editing over FTP but I'm not sure where to start other than ripping the entire directory and dumping it into XAMP.

  • When will microsoft release IE9? [closed]

    - by Rob McKinnon
    I was one of those people early on to try their IE9 beta, and it was terribly buggy. It still does function horribly. IMO any windows release after 5(2k,nt,xp) absolutely sux the life out of my resources compared to RPM linux(opensuse), until at least service pack 2. MS is trying to push HTML5/CSS3 and they cannot pass the Acid 3 test. I am wondering when IE9 will become functional. I am a big supported of MS applications. I have a great amount of adoration for IIS7 because they have support for CGI/PHP. Is IE9 going to be released before 2012?

  • Is it illegal to use content in such a way?

    - by MHZ
    I have a couple of questions about the legality of the content of some websites. I am currently working on two websites and I would like to make sure I am not breaking any laws, by using some content like I am... Do I need to get a license to use images from the Internet (such as google.images.com) in my site, assuming they aren't a company logo belonging to another company? If not, am I allowed to use it after I modify it with a image editing software? If content such as phone numbers, e-mail addresses, website addresses, and text from websites can be found for free online, and I gather this information for a search engine based site that I am working on and offering this information on a paid basis (similar to google, but more specialized), is something that is legal? Note: I am not 'copying' or redirecting business from anywhere, to my site. The exact opposite, the site I am working on actually helps advertise businesses and make it easier for customers to find them.

  • Issue with dynamic Quicklist in Unity

    - by costales
    I would like to add a Quicklist to Gufw app, but it isn't working. The code is here (you can install reading the INSTALL file): http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/files/3 I added lines 52-54 to the view (a simple example) from the official API web: http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/view/head:/gufw/view/gufw.py https://wiki.ubuntu.com/Unity/LauncherAPI self.launcher = Unity.LauncherEntry.get_for_desktop_id ("gufw.desktop") self.launcher.set_property("progress", 0.42) self.launcher.set_property("progress_visible", True) But nothing happen. But if I run this file with Gufw running: http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/view/head:/gufw/test_launcher.py $ python test_launcher.py The progress bar appears! :/ I don't know what am I missing? :P Any idea? Thanks in advance! The environment is Ubuntu 13.04.

  • New website - best practice for requirements specs? [closed]

    - by Alex K.
    Possible Duplicate: Extracting user requirements from a person who does not know how to express himself As a hobby freelancer I'm new to this. I've never had a non-technical client before explain to me what his future website is supposed to do. A person wants me to make a website for him and he basically explained to me what's it about. However, he's not a technical person and he just doesn't understand what I need to know and how to properly describe/explain it to me. When I ask him how a user is supposed to submit an entry to the website he told me "He fills out a form.", which is not really helping me. This was just an example, it goes on for other sections of the website as well which are a lot harder to explain. The website will be aimed at a specific professional user demographic and I have no clue about their profession and how their industry works. I tried to find some good Product Requirements Document templates on Google but none of them really seemed like they could help him understand how to write it so I can understand what he wants/needs. Can somebody please give me a hint on how to deal with such non-technical clients?

  • what do I need to do to get started with a website? [closed]

    - by omar
    I am a student and I have made websites for some companies before but now I would like to make a generic website for myself but dont know how to get started as I never had to deal with hosting or bandwidth before. I am looking to make a website that will provide users with information about me. In the future I might add things such as ordering or buying products but for now the idea is to provide information only. I was told not to go for any webhoster outside of Canada as I might risk the confidential integrity of my users or myself. I have no idea where to get started or what I need. I now also have to deal with possible security issues or security holes I may leave in my website creation... So my question here is: What is a good and reliable webhosting company that can be trusted to some degree?

  • What is the canonical resource on multi-tenancy web applications using ruby + rails

    - by AlexC
    What is the canonical resource on multi-tenancy web applications using ruby + rails. There are a number of ways to develop rails apps using cloud capabilities with real elastic properties but there seems to be a lack of clarity with how to achieve multitenancy, specifically at the model / data level. Is there a canonical resource on options to developing multitenancy rails applications with the required characteristics of data seperation, security, concurrency and contention required by an enterprise level cloud application.

  • How to explain that writing universally cross-platform C++ code and shipping products for all OSes is not that easy?

    - by sharptooth
    Our company ships a range of desktop products for Windows and lots of Linux users complain on forums that we should have been written versions of our products for Linux years ago and the reason why we don't do that is we're a greedy corporation all our technical specialists are underqualified idiots Our average product is something like 3 million lines of C++ code. My and my colleagues analysis is the following: writing cross-platform C++ code is not that easy preparing a lot of distribution packages and maintaining them for all widespread versions of Linux takes time our estimate is that Linux market is something like 5-15% of all users and those users will likely not want to pay for our effort when this is brought up the response is again that we're greedy underqualified idiots and that when everything is done right all this is easy and painless. How reasonable are our evaluations of the fact that writing cross-platform code and maintaining numerous ditribution packages takes lots of effort? Where can we find some easy yet detailed analysis with real life stories that show beyond the shadow of a doubt what amount of effort exactly it takes?

  • As a developer, how do I learn sales? [closed]

    - by Dan Abramov
    I quit the company I was working for to pursuit an opportunity as a startup, and I believe in our product. I'm sure it's going to be great if we attract some customers first to keep going. (I don't want funding.) Our product is targeted at private schools and courses, and helps organize the mess other LMSs introduce. The problem is, our team is basically just me and I have very little idea about sales and marketing. I can do reasonably good copywriting but I'm sure I can do better—and being nervous or too techy in a real world conversation with the client doesn't help. I want to get better, in fact, a lot better at negotiating with clients and pitching my product. I did look for some “sales articles” on the web, and a lot of what I found is plain bullshit on SEO-engineered websites promoting books or $5000 courses. What I need instead is a developer's perspective on how to sale a product you think is great. What are typical programmer's mistakes and misconceptions about sales, and how to avoid them? How do you evolve into a reasonably great salesman? I can't believe it's in the mindset and unlearnable. Your own experience, combined with great articles available on the web is most welcome. To Future Readers The question got closed because it is not a good fit for this site. I found some helpful tips in a similar question asked on a sister StackExchange site about startups: I'm a terrible salesperson. What can I do about it?

  • Software consultancy or in-house developement?

    - by JefClaes
    What are the benefits and drawbacks of working as an in-house developer versus working as a consultant and vice versa? I am pretty sure both breeds can be found on these forums and I hope you are willing to share your experience. Edit: Let me clarify the question. I wonder how the experience is like being a developer. For example: Being an in-house developer, you are able to learn from your mistakes. Being a consultant is often more challenging, because there is more variety in the problems you have to solve. PS: Although I realise that this is a subjective question, I don't necessarily see it as one of those bad-subjective questions.

  • What would it take to get developers to pay for something that is already freely available as open source?

    - by plaureano
    For example, I know that open-source versions of IL readers/writers exist such as Cecil, and Microsoft's (closed source) CCI. What would it take to get developers to pay for something that is already freely available? I have always wanted to start my own ISV by writing my own tools and selling them in the open market, but it's hard to gauge the demand, given that free alternatives already exist. Does anyone else have any successful experiences selling a commercial version of an open-source product?

  • Daily standups- yea or nay?

    - by Fishtoaster
    How valuable (or not) do you think daily stand-up meetings are? If you're not familiar with it, this refers to a daily meeting often pushed by Scrum adherents (and some other general agile proponents). The idea is that you hold a daily meeting, timeboxed to 15 minutes, and in which everyone must stand (to encourage people to be to-the-point). In the meeting, you go around the room and each say: - What you did yesterday - What you plan to do today - Any blockers or impediments to your progress. Do you think this practice has value? Has anyone worked at a place that's done it, and what did you think?
