• Client Side Development - In Process/Completed Indicator Preferences?

  - by Brian

  Hello, I have been doing more client-side development, managing the UI on the client and submitting data to the server via web service calls. I'm not looking for implementation details, but was curious on developer preferences for displaying an operation in process and what to display when completed or even failed. As a for instance, just for clarification sake, what if you are submitting a profile form's data to a web service. I want to display that something's happening to the user, and give them a message that the form submitted successfully. I've in the past used a twitter-style message (that appears at the top), modal dialogs... I was curious what worked for others and any advice (what did the users like/not like, etc.). Again, technical details aren't needed. Thanks.

• Which development Language is best suited to Network Inventory

  - by dastardlyandmuttley

  Dear stackoverflow I hope this is the corrcet type of question for stackoverflow to consider I would like to develop a "Hard Core" application that performs Network Inventory. High level requirements are Work on Windows and UNIX networks it has to be extremly performant it has to be 100% accuarate (massively) scalable and fun to write The sort of details I am after is manufacturer and versions of all major workstation hardware components such as motherboard, network card, sound card, hard drives, optical drives, memory, BIOS details, operating system information etc. I dont want to have to distribute a client on each workstation to collect the information although i will require automatic worksattion discovery I would value your thoughts on the best development language to employ I know there are products such as NEWT and stuff like nmap... I would like to do this type of technical programming myself "from scratch" Warm Regards DD

• Collaborative editing for .NET development - what are the possibilities

  - by Olav

  What are the best options for real-time collaborative editing for .NET development? (C#,VB.NET, ASP.NET - not Mono unless it is the best way to get collaboration) 1) Anything possible with visual studio? 2) Collaborative editors? I know Eclipse has real-time collaboration, but I don't know how far you can combine it with .NET support. 3) Web-based tools? 4) Desktop sharing tools like VNC, NX etc. The main points is that 2 developers in different locations should be able to see edits in real time. Both should be able to edit, or it should be easy to switch control. Regarding .NET, syntax highlighting etc is better than nothing.

• Is Software Development a Part of IT

  - by kzh

  I am not sure if this question is in the scope of SO, but I will ask anyway... I am currently going to school, majoring in Computer Science. Often I overhear students in the Management of Information Systems major call themselves programmers. These comments make me angry for a few reasons: They seem to trivialize what I do. Most of them are not even capable of doing what I can do. To me, MIS is IT and the are technicians and software developers are engineers and are not IT. So I guess my question is, Is software development part of IT? I often see them lumped together.

• Swapping an image during web development

  - by detly

  I'm trying to see what a certain webpage would look like if I replaced a certain image with another. Rather than upload the image, edit the site, etc, each time I tweak it, I'd like to know if there's a way to change the image in the page to my local version while viewing the remote page. I use Firebug for debugging web development usually, but I'm open to any other tool that might do this. (It is absolutely impossible to search for this and find anything but questions about dynamic image swapping on a deployed website, so sorry if this is a duplicate.)

• RoR app running on mongrel development but not production

  - by ANaimi

  Hello all, This is my first stab at Ruby on Rails. Just deployed a very simple app to Heroku. The thing is that my app runs flawlessly on mongrel development; When I run it with "mongrel_rails start -e production" however, I get the error "We're sorry, but something went wrong." For the life of me, I couldn't debug this. Heroku logs is not returning anything, the Exceptional addon in Heroku is not returning anything, and I cannot find mongrel.log on my Windows machine (when I run mongrel using: mongrel_rails start -e production -d" I'm using Rails 2.3.5 and sqlite3 with bundler to pack my gems. I was told that probably rails is not booting up correctly. I can't find any other way to diagnose this. Any ideas? Thanks, ANaimi

• Best Technologies for AJAX Web Development

  - by floatingfrisbee

  Hey Everyone, I have some experience in AJAX development, mostly on .NET and MooTools. However, I want to learn more and see what others out there thought about the various other options available. I am looking more for advise about the front end. The back end, I will most probably be coding up in .NET using c# and WCF services. Please feel free to provide me as much information as you can. Also I would appreciate any links to resources. List of Options (feel free to add) Write my own Javascript Use a frame work like MooTools, JQuery etc. Which one is better? Use Google Web Toolkit. Am I tying myself to limitations of GWT? Or are there not limitations? ASP.NET AJAX WPF (Will this run on non IE browsers?) Flash (it'll be a pain to learn action script) Thanks Jaspreet

• How do I learn Flash Game Development?

  - by grokker

  I'm currently a PHP programmer and one of my childhood dreams is to create a game. The problem is I don't know Flash. I'm not great at drawing stuff or even artistic. I could program a little with JavaScript and I could consider myself intermediate with JQuery. Question How do I get started with Flash Game development? What books do I read first? The type of game is a side scroller about an Indiana Jones type of character and the setting is on the jungle with trees and snakes and a lot of animals.

• Stop Rails from unloading a module in development mode

  - by Gareth

  I have a module in my Rails app that lives in /lib module MyModule mattr_accessor :the_variable class << self def setup yield this end end end From my environments/#{RAILS_ENV}.rb file I can then set an environment-specific value for the_variable: MyModule.setup do |my_module_config| my_module_config.the_variable = 42 end This is lovely, and it seems to work (almost) fine. The problem is that in development mode, Rails via ActiveSupport::Dependencies unloads a load of modules, and reloads them in time for the new request. This is usually a great behaviour because it means you don't need to restart your localhost server when you make a code change. However, this also clears out my initialised the_variable variable, and when the next request comes in the initialiser (obviously) isn't run again. The net effect is that subsequent requests end up having MyModule.the_variable set to nil rather than the 42 that I'm looking for. I'm trying to work out how to stop Rails unloading my module at the end of the request, or alternatively find another way to cleanly provide environment specific configuration for my modules. Any ideas? :-/

• Java technologies for web-development.

  - by Alex

  Hello. I'm PHP-programmer, but I'm extremely interested in learning Java. So I decided to change speciality from PHP to Java. At the moment I have an opportunity to try to make quite simple web-application (it should contain 2-3 forms, several pages with information from the database and authorization module) and also I have a chance to choose any technology I want. Besides I have about 3 months for this task. I've decided to develop site with Java technologies for the purpose of studying. I've already read a book about Java ("Java2 Complete Reference" by P.Naughton) and currently I'm reading "Thinking in Java" by B.Eckel. I clearly understand it's not enough for efficient development, but I want, at least, to try. I would be very appreciated for the advises, which framework (for example) or technology to choose (Spring, Grails etc.) and what primary aspects and technologies of Java should I pay attention to? Thank you in advance.

• Development life-cycle for making an application?

  - by Mohit Deshpande

  I have an idea that I want to make into an application (I have a C/C++, C#, and Java programming background so I will be developing in QT Creator for cross-compilation's sake). So now I am asking you senior developers, what should I do next? I know that all good programs come from an idea. Then what should I do? Prototype the UI? Then develop the code? Is there like a circle of the development of an application? I DO NOT MEAN FOR THIS QUESTION TO BE SUBJECTIVE OR ARGUMENTATIVE

• Apple Mac Software Development

  - by MattMorgs

  I'm planning on developing an Apple Mac application which will collect hardware information from the host Mac and also installed software info. The hardware and software info will be collected in an encrypted XML file and then posted back to a website. The application should run as a "service" or background process on the Mac and can be configured to collect the data on a frequent basis defined by another encrypted XML config file. I've done plenty of Windows based software development but never on the Mac. Can anybody point me in the direction of any useful info on how to develop on the Mac, collect hardware and software info, export to an XML file, file encryption and packaging a compiled app to run as a service? Is either Objective C, Cocoa or Ruby a possible option? Many thanks for your help in advance!

• Speed, delta time and movement

  - by munchor

  player.vx = scroll_speed * dt /* Update positions */ player.x += player.vx player.y += player.vy I have a delta time in miliseconds, and I was wondering how I can use it properly. I tried the above, but that makes the player go fast when the computer is fast, and the player go slow when the computer is slow. The same thing happens with jumping. The player can jump really high when the computer is faster. This is sort of unfair, I think, because. Should I be doing this someway else? Thanks.

• How do I Integrate Production Database Hot Fixes into Shared Database Development model?

  - by TetonSig

  We are using SQL Source Control 3, SQL Compare, SQL Data Compare from RedGate, Mercurial repositories, TeamCity and a set of 4 environments including production. I am working on getting us to a dedicated environment per developer, but for at least the next 6 months we are stuck with a shared model. To summarize our current system, we have a DEV SQL server where developers first make changes/additions. They commit their changes through SQL Source Control to a local hgdev repository. When they execute an hg push to the main repository, TeamCity listens for that and then (among other things) pushes hgdev repository to hgrc. Another TeamCity process listens for that and does a pull from hgrc and deploys the latest to a QA SQL Server where regression and integration tests are run. When those are passed a push from hgrc to hgprod occurs. We do a compare of hgprod to our PREPROD SQL Server and generate deployment/rollback scripts for our production release. Separate from the above we have database Hot Fixes that will need to be applied in between releases. The process there is for our Operations team make changes on the PreProd database, and then after testing, to use SQL Source Control to commit their hot fix changes to hgprod from the PREPROD database, and then do a compare from hgprod to PRODUCTION, create deployment scripts and run them on PRODUCTION. If we were in a dedicated database per developer model, we could simply automatically push hgprod back to hgdev and merge in the hot fix change (through TeamCity monitoring for hgprod checkins) and then developers would pick it up and merge it to their local repository and database periodically. However, given that with a shared model the DEV database itself is the source of all changes, this won't work. Pushing hotfixes back to hgdev will show up in SQL Source Control as being different than DEV SQL Server and therefore we need to overwrite the reposistory with the "change" from the DEV SQL Server. My only workaround so far is to just have OPS assign a developer the hotfix ticket with a script attached and then we run their hotfixes against DEV ourselves to merge them back in. I'm not happy with that solution. Other than working faster to get to dedicated environment, are they other ways to keep this loop going automatically?

• What are the leading professional journals in software development?

  - by Austin Hyde

  In one of my classes, we were asked to research the top professional journals in our field. According to what I can dig up, the ACM and IEEE journals are the "best", as they come up at the top of my searches and this question. However, there are a dozen or so individually topic-ed journals for each, with no very clear measure of which one is most useful, popular, etc. For example, "IEEE Software" vs. "IEEE Transactions on Software Engineering". So, what do you consider to be the "leading" professional journals (specifically), and why? It doesn't have to be only ACM or IEEE, either. If you know of another, please add it.

• How much should I charge an hour for freelance iOS development?

  - by Tyler Bell

  I am a fairly competent developer who already holds a job developing iOS applications. This job is through the university which I attend. The producer of the apps that I develop is always trying to set me up with some freelance opportunities to get my work out there and to get me some more work/experience. What is a reasonable price to charge (either hourly or per app)? I'd be working by myself, on my own equipment, from start to finish in the design process. Just wondering what a reasonable price was...I've heard up to $30? Thanks

• C or assembly code to find current cpu core speed

  - by honestann

  How can my application efficiently determine the following information peroidically while it executes: 1: current speed of each of the 8 CPU cores. 2: which core the code is currently executing on. My application is C and assembly-language, so any solution in either C or assembly-language is fine. This code needs to execute quickly, so creating, reading and processing a file generated by "cat /proc/cpuinfo" is much too slow. The cores slow-down and speed-up automatically, probably to keep CPU temperature under control. Therefore, a one-time measure is not sufficient for my purposes. My application already reads and subtracts the cpu cycle counter in assembly language to determine number of clock cycles, but my program cannot compute elapsed time in nanoseconds unless it knows the current clock frequency of the cpu cores (and which core the code is executing on). Thanks!

• Best practices when loading images for improving page loading speed

  - by Naoise Golden

  I am working on optimizing a page's loading speed. Here are some analytics: Notice how the images, although only accounting for 65% of the total size (1.1MB), are by far the slowest loading assets: 96% of time. I'd like to know which are the recommended practices on optimizing loading speed, only taking images into account. Some of the techniques we are already applying: image compression images hosted on cookieless domain and CDN spriting everything that can be sprited http headers: keep alive and Expires to one year. Disclaimer: I have gone through the available documentation, I think by focusing on image loading optimization I am not creating a duplicate or a subjective question.

• System monitor network speed monitor not working for LAN but works for my Wi-fi

  - by Pavak

  I'm on Ubuntu 13.10. I generally use wi-fi to connect to the internet. But Yesterday my wi-fi router occurred some problem and now it's out for warranty. So temporarily I'm using LAN. System monitor displayed the network speed correctly when I was in wi-fi. But now it's not showing any kinda network speed in System Monitor. I checked the preferences opption but couldn't find a way. I also checked "ksysguard"(KDE's system monitor) and conky. None of them working. How can i solve this? I'm attaching a screenshot to clear the problem.

• What programming language and framework has best support for agile web development?

  - by Jonas

  If I would like to quickly set up a modern website, what programming language + framework has best support for this? E.g. short and easy to understand code for a beginner and a framework with support for modern features. Disregard my current knowledge, I'm more interested in the capacity of web programming languages and frameworks. Some requirements: RESTful URIs: http://example.com/category/id/page-title similar to the urls here on Programmers. ORM. A framework that has good database support and provide ORM or maybe a NoSQL-database. Good support for RESTful WebServices. Good support for testing and unit testing, to make sure the site is working as planned. Preferably a site that is ready to scale with an increasing number of users.

• Why isn't Java used for modern web application development?

  - by Cliff

  As a professional Java programmer, I've been trying to understand - why the hate toward Java for modern web applications? I've noticed a trend that out of modern day web startups, a relatively small percentage of them appears to be using Java (compared to Java's overall popularity). When I've asked a few about this, I've typically received a response like, "I hate Java with a passion." But no one really seems to be able to give a definitive answer. I've also heard this same web startup community refer negatively to Java developers - more or less implying that they are slow, not creative, old. As a result, I've spent time working to pick up Ruby/Rails, basically to find out what I'm missing. But I can't help thinking to myself, "I could do this much faster if I were using Java," primarily due to my relative experience levels. But also because I haven't seen anything critical "missing" from Java, preventing me from building the same application. Which brings me to my question(s): Why is Java not being used in modern web applications? Is it a weakness of the language? Is it an unfair stereotype of Java because it's been around so long (it's been unfairly associated with its older technologies, and doesn't receive recognition for its "modern" capabilities)? Is the negative stereotype of Java developers too strong? (Java is just no longer "cool") Are applications written in other languages really faster to build, easier to maintain, and do they perform better? Is Java only used by big companies who are too slow to adapt to a new language?

• What expectation should I have of South African web development rates / duration? [closed]

  - by Warren van Rooyen

  I am a developer but only intend on doing the front-end work for getting Reddit-like upvote / downvote functionality going on an upcoming site I'm building. I have never had to contract a developer for back-end work to implement code for me so I am quite in the dark on how much I should expect to pay and how long it could take to get the site going. I could be taken for a ride as the developer could distort the time it would take at a seemingly regular rate (hourly/day) or could otherwise distort their rate. Please could you give me help on this. I know you need some guidance on the nature of the site so here it is. I have a Reddit type template with CSS and PHP included. I then downloaded Pligg code that's intended to do the job of the Reddit upvote downvote functionality. How long would a developer roughly need to unite the theme and front end with the back-end functionality? I do understand it's not a lot of info but I'm sure you're experienced enough to have an instinct for the size of the project. Also, should I work on an hourly/day rate/ project payment agreement?
