  • Planning a skillset for a fallback career [closed]

    - by Davy Kavanagh
    I'm not too certain this is a SO question, but I didn't think it belonged in meta either. Long story short, I am bioinformatics researcher. I like to code, it's my favourite part of the job. I have been thinking for a while that if academia is not kind to me, I might seek a career in software development. My current contract is for three years and I would like to spend some time over the next 3 three years learning and practicing software development as possible. Python seems like a popular language and it what I mostly use to do things for me, but I am also in heavy use of R. So my main question is: Are python and R good things to be learning with a sotfware dev goal in mind, and if so, is there any particular type of programming or software that might be useful to have experience with. Hard questions to answer I know, but I thought I would get the answer from people who are in the know. Cheers, Davy.

  • Costs and Scope in developing a typical iphone application

    - by ali
    Iam new to iphone development and have been tasked to development a fairly simple iphone application. It would basically show listings of information eg accommodations, restaurants...around 8-9 different types. Drilling on one would show the details of it. These are dynamically sourced from a db (through an xml feed) that powers an existing website. Also users should have ability to save favourites and also an interactive google map showing locations of these places. Just would like to know how long would such an iphone application take to develop and what would it costs. As iam new to iphone dev, i do not know how big the scope is, any complications to anticipate, scope creep issues, and how much to charge. Want to give a reasonable estimate so that i dont overcharge.

  • Update JSON file C# W8 development

    - by AndrewB
    At the moment, I've got a JSON file with content looking like this: { "username": "test", "someNumber":100 } I'm using JSON.Net to fetch the .JSON file from a webserver - C#: var http = new HttpClient(); http.MaxResponseContentBufferSize = Int32.MaxValue; var response = await http.GetStringAsync(URI); var result = JsonConvert.DeserializeObject<DatClass.Result>(response); This works great together with the class getting/setting the properties. However, what I would like to know is whether there's a good way for a user to update the .JSON file through a textbox UI? As in: [textbox - update username] [update button] - username sent to server - .JSON file updated - [textblock - showing updated username in UI]. I'm not looking for exact code solutions, I'm rather looking for good solutions on this, and/or if this is a terrible idea of an easy database(?).

  • Virtual PC 2007 as programming environment

    - by Gern Blandston
    I'd like to create a VM in Virtual PC 2007 for use as a development environment/sandbox for an existing ASP.NET application in Visual Studio 2005/SQL Server 2005 (and VSS for source control). I'm thinking that I need to create a 'base' copy of the environment (with the os, Visual Studio, and Sql Server), and then copy that to a 'work' version that I do actual development in. I would be sharing this VM with one or two other developers who would be working on different parts of the app. Is this a good idea? What is the best way to get my app/databases in and out of the VM and the changes I make into VSS? Is it just a copy from the host location to the VM share and back again? How do I keep everything synchronized? Thanks!

  • Android Development Device

    - by jamesaharvey
    I'm looking to get a device (phone, tablet, etc.) for developing Android applications. I know I can use the emulator to get me started, but I feel like that will only get me so far along. I'm looking for something reasonably priced, and I don't want a phone contract, data plan, etc. Anyone have any suggestions?

  • Blackberry app development - Drawing graphics on top of rendered text/buttons etc

    - by paullb
    Based off the one of the demos I have the following code. Currently what displays in the simulator is just hte contents of the paint function, however the ObjectChoiceField is still selectable if one happens to click in the right location. I would like both the text contents and the paint function contents to appear. Is this possible? public CityInfoScreen() { //invoke the MainScreen constructor super(); //add a screen title LabelField title = new LabelField("City Information Kiosk", LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH); setTitle(title); //add a text label add(new RichTextField("Major U.S. Cities")); //add a drop-down list with three choices: //Los Angeles, Chicago, or New York //... String choices[] = {"Los Angeles","Chicago","New York"}; choiceField = new ObjectChoiceField("select a city", choices); add(choiceField); Manager man = this.getMainManager(); } ... public void paint(Graphics g){ super.paint(g); // g.drawRect(0,left,500,500+left); g.setGlobalAlpha(0); g.drawRect(100-left,100-top,200,200); String text = new Integer(left).toString(); String text2 = new Integer(top).toString(); g.drawText(text + " " + text2,120-left,120-top); }

  • Best C++ development environment in Linux

    - by Bruce
    I have some experience with Eclipse and Qt creator and am somewhat disappointed in their debuggers, less so in their editors. On Windows, I like Visual Studio for debugging and SlickEdit for editing (SE is also available on Linux). Is there an IDE that is somehow better than the two mentioned?

  • HTML5 applicationCache in local development

    - by jesper
    I'm experimenting with application cache based on this example: http://html5demos.com/html5demo.manifest This example works fine in ff, but when I create analogous site (almost identical) I get only status "UNCACHED (numeric value 0) -- The ApplicationCache object's cache host is not associated with an application cache at this time." I work on xampp and I've set correct mime-type. When the page is loading ff "is asking to store data on your computer for offline use" and when I show Tools - Options - Advanced - Network - Offline data there is localhost but with 0B size.

  • what are the limitations of mobile phones and web development

    - by Kieran
    simple really.. I am have been asked to do a mobile site (straight html + css (+ maybe jquery mobile later on)). The site will need to support the new type smart phone and the old type Nokia/(Symbian OS) with the web browser. Doubts and reservations aside as to anyone without a smart phone would bother visiting this site it still needs to support it. My first question is do older phones support PNG images and transparancey... But this has led me to a much broader question of what are some of the limitations of developing for older phone platforms is there anything that has caught mobile web devs out and had them scratching their head for an afternoon.. what are the limitations of mobile phones?

  • Best windows iphone app development alternative

    - by Nash0
    What do you think is the best way to develop iphone apps on windows? What are the pros / cons of your method, and why do you use it over other options? How complex is your method in relation to other options? I am more interested in standalone and web apps but fell free to discuss gaming graphics. Yes I know you need to build on a mac to be able to put it on the app store, so no "use a mac" answers please.

  • ajax page works in development (vs2010) but does a full postback on production win2k8R2

    - by merk
    Hi all, I have a stupid simple page. I've got a panel and a button. Clicking the button either hides or displays the panel. That much works. I added in a script manager control and update panel - put all the page contents in the updatepanel/contenttemplate When i run this under vs2010 and click the button, the page does NOT post back - the panel just appears or disappears without the whole page refreshing, which is what i wanted. I upload this to my IIS7.5 server and the page is posting back/whole page is refreshing when i click the button. Do i need to configure anything on the server to enable ajax? thanks

  • Web-Application development startup advice

    - by rpr
    Dear programmers of StackOverflow, recently me and two of my friends from college started a software company. We are developing web-applications using GWT-Spring-Hibernate and other helper frameworks. In a couple of months, we managed to set up a stable back-end and produced some demo programs for CRM solutions. Our area of interest is CRM where we can combine the flexibility of our back-end with the slick looking GWT based GUIs. Unfortunately we live in a third world country (well, kind of two and a half :) and no one here gives our work enough credit, or really cares about the advantages of web-apps. We are stuck at the moment because our current clients do not want to pay that much money for just "putting their local app on the web". Since we can not find satisfying work here, we have decided to work online/international. I was wondering if you guys know a good freelance kind of sites where we can throw ourselves into the market.. Also a question from frustration, to those who are in the field or knowledgeable/interested about web based CRM, how much would you ask/pay for lets say a web app which will keep track of all the patients of a multi-branch clinic also allowing the patients to access to view their own records? Including tiered authorization, logging etc.. Many thanks in advance for your responses!

  • As a team should we develop locally and merge into the dev server, or develop on the dev server?

    - by CogitoErgoSum
    Hey, Recently I was tasked with writing up formal procedures for a team based development enviroment. We have several projects with multiple modules each. Right now there are only two programmers, however there are plans to expand to 4-6 programmers. Each programmer will be working on the same project and possibly pages which may cause over writing or error issues. So far the ideal solution I have thought up is: Local development (WAMP/VM or some virtual server instance on their own machine). Once a developer has finished their developments, they check it into the CVS Repository and merge it wih other fixes etc. The CVS version is then deployed to the primary dev server for testing by the devs. The MySQL DAtabases are kept on the primary dev server and users may remotely connect to it. Any Schema / Data alterations are run through a DB Admin who will notify all devs of any DB Changes (Which should be rare). Does anyone see an issue with this or have a better solution?

  • Test-driven Development: Writing tests for private / protected variables

    - by Chetan
    I'm learning TDD, and I have a question about private / protected variables. My question is: If a function I want to test is operating on a private variable, how should I test it? Here is the example I'm working with: I have a class called Table that contains an instance variable called internalRepresentation that is a 2D array. I want to create a function called multiplyValuesByN that multiplies all the values in the 2D array by the argument n. So I write the test for it (in Python): def test_multiplyValuesByN (self): t = Table(3, 3) # 3x3 table, filled with 0's t.set(0, 0, 4) # Set value at position (0,0) to 4 t.multiplyValuesByN(3) assertEqual(t.internalRepresentation, [[12, 0, 0], [0, 0, 0], [0, 0, 0]]) Now, if I make internalRepresentation private or protected, this test will not work. How am I supposed to write the test so it doesn't depend on internalRepresentation but still tests that it looks correct after calling multiplyValuesByN?

  • iPhone Development - CoreData runtime error

    - by Mustafa
    I'm facing a strange CoreData issue. Here's the log: 2010-04-07 15:59:36.913 MyProject[263:207] <MyEntity: 0x180370> (entity: MyEntity; id: 0x17e890 <x-coredata://0F55C533-41BD-4F09-9CCA-0CB304CAB065/MyEntity/p380> ; data: <fault>) 2010-04-07 15:59:36.918 MyProject[263:207] *** Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'The NSManagedObject with ID:0x17e890 <x-coredata://0F55C533-41BD-4F09-9CCA-0CB304CAB065/MyEntity/p380> has been invalidated.' I have a hierarchy of UITableViewControllers that use NSFetchedResultsController to populate the table, and when a particular row is selected, the detail view is shown. UITableView (MyMainEntity) UITableView (MyEntity) UITableView (MyEntity) detail view Both MyMainEntity UITableView and MyEntity UITableView use NSFetchedResultsController to show the records. Sometimes it crashes when i'm scrolling the tableView, and sometimes it crashes when i try to open the detail view. I can navigate to the MyEntity detail view multiple times before application crashes. What does this error mean? and how can i fix it!?

  • Windows DDK development with MinGW?
