• Client-side or server-side processing?

  - by Nick

  So, I'm new to dynamic web design (my sites have been mostly static with some PHP), and I'm trying to learn the latest technologies in web development (which seems to be AJAX), and I was wondering, if you're transferring a lot of data, is it better to construct the page on the server and "push" it to the user, or is it better to "pull" the data needed and create the HTML around it on the clientside using JavaScript? More specifically, I'm using CodeIgniter as my PHP framework, and jQuery for JavaScript, and if I wanted to display a table of data to the user (dynamically), would it be better to format the HTML using CodeIgniter (create the tables, add CSS classes to elements, etc..), or would it be better to just serve the raw data using JSON and then build it into a table with jQuery? My intuition says to do it clientside, as it would save bandwidth and the page would probably load quicker with the new JavaScript optimizations all these browsers have now, however, then the site would break for someone not using JavaScript... Thanks for the help

• Secure database connection. DAL .net architecture best practice

  - by Andrew Florko

  We have several applications that are installed in several departments that interact with database via Intranet. Users tend to use weak passwords or store login/password written on a shits of paper where everybody can see them. I'm worried about login/password leakage & want to minimize consequences. Minimizing database-server attack surface by hiding database-server from Intranet access would be a great idea also. I'm thinking about intermediary data access service method-based security. It seems more flexible than table-based or connection-based database-server one. This approach also allows to hide database-server from public Intranet. What kind of .net technologies and best practices would you suggest? Thank in you in advance!

• How to make external Mathematica functions interruptible?

  - by Szabolcs

  I had an earlier question about integrating Mathematica with functions written in C++. This is a follow-up question: If the computation takes too long I'd like to be able to abort it using Evaluation Abort Evaluation. Which of the technologies suggested in the answers make it possible to have an interruptible C-based extension function? How can "interruptibility" be implemented on the C side? I need to make my function interruptible in a way which will corrupt neither it, nor the Mathematica kernel (i.e. it should be possible to call the function again from Mathematica after it has been interrupted)

• Is there any software made by microsoft using .NET?

  - by SnOrfus

  I've been reading some blogs and articles lately and one thing I noticed a couple of times was authors stating that Microsoft 'doesn't use their own technologies' with respect to developing applications using the .NET framework (specifically, desktop applications). There's not a whole lot of information that I can see as to what platforms their products are developed with. I had heard that Media Center has some .NET code, but not 100%, likewise with SQL Server Management Studio. So the question I ask is, does anyone know of any software, made by Microsoft that is 100% .NET code?

• How to build a Video Broadcaster, which can handle more than 20,000 viewers

  - by Gaurav Srivastava

  I want to broadcast Video from a web cam, over internet. The problem is, the Video will be viewed live by more than 20,000 people (expected). I have a very little experience with Red5 Broadcasting. I did some broadcasting using Red5 and Flash. It works fine for 1 or 2 viewers i.e. it is great for personal chatting/ video conferencing applications. But, when the number of viewers increases, the delay in Broadcasting also increases. I am experiencing a Delay addition of about 0.5 Seconds for every new user who joins the broadcast. Can any one suggest me some, better technologies on which I can work out this Live Broadcasting. I don't want to use http://www.ustream.com; I want to create one of my own, such tool. But thats always the last solution.

• WCF Caching Solution - Need Advice

  - by Brandon

  The company I work for is looking to implement a caching solution. We have several WCF Web Services hosted and we need to cache certain values that can be persisted and fetched regardless of a client's session to a service. I am looking at the following technologies: Caching Application Block 4.1 WCF TCP Service using HttpRuntime Caching Memcached Win32 and Client Microsoft AppFabric Caching Beta 2 Our test server is a Windows Server 2003 with IIS6, but our production server is Windows Server 2008, so any of the above options would work (except for AppFabric Caching on our test server). Does anyone have any experience with any of these? This caching solution will not be used to store a lot of data, but it will need to be fetched from frequently and fast. Thanks in advance.

• How do I implement a Google Latitude check-in feature on Windows Mobile?

  - by Carnotaurus

  I hope this is the correct forum. I wish to write a mobile application (MVC 4 mobile app) that extends Google Latitude for Windows Mobile 7 (or version 8 when launched in November). However, according to Google's own website (see http://www.google.com/mobile/latitude/), the check-in feature is not supported on Windows Mobile. So, how would I implement such a feature (not so interested in the UI here) using the technologies that I have mentioned? EDIT The implementation needs to store check-in data against a Google Latitude account.

• Point subdirectory to another domain is IIS 6

  - by Liviu

  Is it possible to rewrite somehow www.mysite.com/Pictures to point to test.mysite.com/Pictures or even more broadly www.someothersite.com/Pictures ? Note: www.mysite.com and test.mysite.com are on separate machines and built with different technologies (one is ASP.NET and the other is PHP) but I have access to both of them. I want that when I reference a picture like www.mysite.com/Pictures/pic12345.png the picture to display correctly, even though there is not /Pictures folder on that server and the pictures has to be retrieved by going to test.mysite.com/Picture/pic12345.png Ideally I want to do this in IIS6 to test it. However I am interested if it possible to do in any webserver (Apache, IIS7)

• Learning Objective-C 2.0 and ASP.NET 4.0 simultaneously?

  - by Sahat

  (HOBBY) I own a Macbook Pro and iPod Touch so developing iPhone/iPod/iPad apps seems like a logical thing to do in order to get some experience in the programming field. Besides I want to write a new application similar to the Capsuleer (Character skills monitor app for EVE Online MMO) but with more features. It's something I'd love to have on my own iPod Touch and I am sure other people will welcome a new EVE Online app for their iPhone or iPod Touch. (CAREER) I want to learn ASP.NET (and possibly Silverlight later on) for my potential future job. I plan to work in the .NET field, so it's a good idea for me to start learning C# and ASP.NET ASAP. Is it a good idea to learn completely unrelated technologies at the same time? Or would it be better to learn one thing at a time? Objective-C first, and ASP.NET second. Or vice versa. Thanks, Sahat

• Tuning JVM (GC) for high responsive server application

  - by elgcom

  I am running an application server on Linux 64bit with 8 core CPUs and 6 GB memory. The server must be highly responsive. After some inspection I found that the application running on the server creates rather a huge amount of short-lived objects, and has only about 200~400 MB long-lived objects(as long as there is no memory leak) After reading http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html I use these JVM options -Xms2g -Xmx2g -XX:MaxPermSize=256m -XX:NewRatio=1 -XX:+UseConcMarkSweepGC Result: the minor GC takes 0.01 ~ 0.02 sec, the major GC takes 1 ~ 3 sec the minor GC happens constantly. How can I further improve or tune the JVM? larger heap size? but will it take more time for GC? larger NewSize and MaxNewSize (for young generation)? other collector? parallel GC? is it a good idea to let major GC take place more often? and how?

• What programming/techy name should I give my new pup? [closed]

  - by Nate

  I am getting a Border Collie puppy tomorrow. If I can get my wife to agree to do so I want to give it a techy/programming type of name. The vast majority of my development is in Microsoft .NET / C# on mobile devices (WinMo and tablets) as well as Silverlight and ASP.NET. I would like the name to be something in that area although I am open other technologies, etc. I have not seen him yet. I assume he is typical Border Collie colored - black/white. One name that crossed my mind is Xaml (pronounced Zammel). What other name ideas do you have?

• How can I integrate Octopress into my Rails app?

  - by BeachRunnerFred

  I'm diving into web development and I built my personal website using Ruby on Rails 3.1 and I'd like to add a blog to it. Octopress sounds really awesome, and it's written in Ruby, but I can't find a single resource online that discusses integrating Octopress into a Rails app. I know that's not what it was designed for, but I'm amazed there's no discussion on it considering the popularity of these two technologies. The only resources I can find are discussions on using Octopress to create a stand-alone blog website. How can I integrate Octopress into my existing Rails 3.1 app? Can I set it up as a stand-alone website and integrate it as a sub-domain? Other suggestions? Thanks so much in advance for your wisdom!

• What lessons can you learn from software maintanence?

  - by Vasil Remeniuk

  Hello everyone, In the perfect world, all the software developers would work with the cutting edge technologies, creating systems from the scratch. In the real life, almost all of us have to maintain software from time to time (unlucky ones do it on a regular basis). Personally I first 2 years of my career was fixing bugs in the company that no longer exists (it has been taken up by Oracle). And probably the biggest lesson I've learned that time - despite of the pressure, always try to get as much information about the domain as possible (even if it's irrelevant to fixing a specific bug or adding a feature) - abstract domain knowledge doesn't lose value as fast as knowledge about trendy frameworks or methodologies. What lessons have you learned from maintenance?

• Can I expose MySQL data using PHP and OData?

  - by user359796

  As I understand it, OData is just a standardized way to expose relational data RESTfully. If I've got a PHP application, it should be able to process those RESTful requests and manipulate a MySQL database based on the request data and then return an ATOM feed. First, are the preceeding statements correct? Second, does a PHP library to do this already exist or would I have to create my own? If I have completely misunderstood these technologies and my question doesn't make sense, please feel free to let me know.

• Job hopping etiquette

  - by Paul Tomblin

  I need to get out of a bad situation at my current work - I like the work, but they've been jerking me around with contract extensions coming at the last minute. I've been offered a job at a different company that doesn't look as interesting, but it's a chance to learn a few technologies I was interested in learning. It's "6 months contract to permanent" - does that mean that if I decide it's hopelessly boring and quit after the 6 month contract period that it won't reflect too badly on me and ruin my reputation in the town? What if I quit earlier than that? Edit I should mention that I don't think there will be one right answer, so rather than accepting one answer, I'm going to vote up the good ones.

• PHP vs JSP Which is should I use/learn for my project?

  - by Jon

  I'm planning on making a fitness planning web application for my senior project at school. However, I don't know anything about either technology and my only experience with web development previously was with python and django. I was wondering what people might recommend to learn, what is most useful to learn for the job market, and what would be best for this project. If it matters, the programming languages I know are, C, C++, Java, and Python. My goal of the project is to learn technologies that will make me a more marketable person. Thanks

• Where do current (not HTML5) browsers stand on clipboard support for non-text data?

  - by John

  I don't really know where the line is between the browser itself and HTML/JS here. But let's say I want to write a web-app where I can copy a chunk of data from MSPaint (select, CTRL+c) and paste it into a web-page in some way... ultimately the point is the data goes to the server without me having to save it as a file first. Where are the problems here - browsers or client-side technologies? For instance if JS can't do it, could Flex/Silverlight? Advice on future technology welcome, but doesn't really answer the question - where are we right now with IE/FF/Chrome and JS/Flex/SL?

• is XULRUNNER suitable as a replacement for other C++ desktop applications frameworks such as QT?

  - by Gabriel Cuvillier

  XulRunner/Gecko seems to be really interesting for developing gui-intensive applications (by using widely used technologies such as HTML / CSS / SVG / XUL / Javascript). But the underlaying C++ APIS (XPCOM, NECKO, ...) looks so old and complex. Moreover the general lack of documentation/developper tools is really frightening. On the other hand, QT have a quite nice platform, and is well documented and supported. The UI part is really "traditional" though. What are your experiences with XULRUNNER, specially compared to other C++ desktop applications frameworks such as QT/GTK/MFC...? What is missing? What is awesome? Side question: If I wanted to migrate an existing MFC app to a cross platform C++ desktop application framework, would it be wise to use XULRUNNER instead of QT or GTK?

• WCF for the totally clueless

  - by Kyralessa

  I've been hearing about WCF for a couple of years now, and I still don't get it. I understand that it's supposed to be a replacement for web services, remoting, MSMQ, and a few other things. The trouble is, every tutorial I find assumes that I've done one of those things, and it tends to follow the line of "Here are the differences; you know the rest." But I don't know the rest! So: Do you know of any tutorial articles, books, etc. that assume that the reader knows C# or VB .NET, but nothing about web services, MSMQ, remoting, and all those other technologies that WCF replaces?

• Is Python good for highload web projects?

  - by Vitali Fokin

  Hello! I decidet to start my own web project. It should be highload project, and I can't decide which technologies should I use. I'm good in ASP.NET MVC, but I like languages like Python more than C#. I read a lot about Python and Django/Pylons/etc but I didn't find any good examples of highload projects on python. So, the question is: Is Python good for highload project? Is it enough fast? And if it is, are python frameworks like django/pylons/etc good for this? Or asp.net mvc will be better choice? PS, I'm not interesting in Java, Ruby and PHP :) So, I'm choosing only between Python + django/pylons/etc and asp.net mvc. Thanks in advance. Please, don't make holywars :)

• Achieving AES-256 Channel Encryption with the .NET Compact Framework

  - by Ev

  Hi There, I am working on a business application where the clients are Windows Mobile 6.1 Professional devices. The server is a Java enterprise application. The industry working group recommends AES-256 encryption for client/server communications. This is necessary to gain certification. The encryption doesn't necessarily need to be channel encryption, it could be payload encryption. Channel encryption is preferable. The client and server communicate using SOAP/HTTP, which we are yet to implement. We plan to use WCF on the compact framework. In order to alleviate some of the work required to implement manual encryption/decryption, it would be nice if we could achieve the required encryption either at the TLS level, or somehow using the WS-* standards (I'm not particularly familiar with that group of technologies but I am learning right now). The server supports https with 256-bit AES. Does anybody have an idea on the best way to implement this? Thanks in advance.

• Easy way for Crystal Reports to MS SQL Server Reporting Services conversion

  - by scoob

  Is there a way to easily convert Crystal Reports reports to Reporting Services RDL format? We have quite a few reports that will be needing conversion soon. I know about the manual process (which is basically rebuilding all your reports from scratch in SSRS), but my searches pointed to a few possibilities with automatic conversion "acceleration" with several consulting firms. (As described on http://www.microsoft.com/sql/technologies/reporting/partners/crystal-migration.mspx). Do any of you have any valid experiences or recomendations regarding this particular issue? Are there any tools around that I do not know about?
