I'm setting up keyboard shortcuts for a web app, and I'm wondering: What are the most commonly used keyboard shortcuts (in web applications)? For example, Google's gmail and reader uses j / k : previous/next o / Enter: open/expand which seems to have stuck, but they also use p/n: previous / next message ...which to me see...
What's the point of the auto-generated 'designer' files in ASP.NET MVC Web Apps? I'm trying out ASP.NET MVC (coming from ASP.NET Webforms projects), so I'm used to just having the one code file with each ASP.NET markup file (.aspx, .ascx etc.). Can I use the code beside model with MVC Apps instead as less files seems simpler? Thanks. ...
I want to improve the page load times of a web site. It is a web application (think something like web mail) with relatively few users that spend long periods using the site. As almost all page requests are from users that have already used the site, images, css and external javascript resources will have been cached by the browser dur...
I want to add small images-arrows for moving up and down on table row in Javascript (maybe jQuery) and save the reordered table (only the order) in cookie for further use. An example would be - Joomla, inside the admin area in the Articles area (but that is done with php). Thanks. ...
I was just wondering whether there is some way to do this: I have a form in a web page, after the user submits the form, the page is redirected to another static HTML page. Is there any way to manipulate the data in the second HTML page without the help of any server code? I mean can I display the form data that the user submitted in ...
How would I run both of them under one main website, say www.example.com, which is written and deployed using a Visual Studio ASP.Net MVC web application project, and where an ASP.Net Web Forms website, would run from a subdirectory of the main site, say www.example.com/myapp? ...
My question is of the chicken and egg variety -- I want to get a job working on high-traffic, highly scalable websites, but I don't have much experience with high-volume sites. I've worked on dozens of web applications in my career spanning almost a decade. Most of these projects have been smaller, intranet systems or public websites th...
I would like to hear other people's advice on when one should build a web application versus building a thick client. Over the last few years, I have participated in several discussions about whether an application should be built (or an old application upgraded) with a web browser interface. Usually these were internal systems used wi...
I need to submit data from a web application to console application. The current plan calls for the web app to submit data to the database and the console app to poll the database then act on the data when it is inserted. Should I change the console app to include an http handler that the web app can submit data so it doesn't have to p...
When you run: rake db:migrate the only files that are being processed are those in db/migrate/ right? Well since relationships such as one-to-one, one-to-many and many-to-many are defined in the in app/models/ , how does Rails enforce such relationships? After I do my migration and look at the generated database schema, I can't see a...
I consider there to be a distinct difference between "Web Services" and "web services" and find myself referring to the latter as "lower case web services". I'd loosely list the differences as: "Web Services" most conforming to the W3C definition based around the WS-* stack enterprise-level mature and dependable strong focus on indu...
I have a small application that I'm developing, that I may want to give/sell to others. I want to persist some settings, and create an admin interface to modify them. What would be the best way to store them away? A DB table seems like overkill for the 10-20 settings I'll have, and I want the retrieval of these settings to be as fast ...

I am looking into creating a web application that plays back musical tablature and I am hoping to find out what the best framework would be prior to investing an enormous amount of time programming it. Here is a visual of what I'm hoping the product would look like when finished: Guitar tablature is a great way to learn music and pic...
I am looking to allow users to select a pre-uploaded image to a user generated web page. I have a list of the available images, so I could easily do this with a select control, however, I'd really like to allow the users to select from a pop up of thumbnails, rather than text, then have that populate a text form element with the resulti...
Has anybody used a local instance of SQLEXPRESS on a web server for serving up read only/mostly content? It seems a read-only database with no referential integrity, denormalized tables, indexes galore, etc. could perform well. Is this a completely horrible idea? And if so, why? ...
So our war file recently ballooned from about 55MB to over 100MB. At which point, deploy by upload in admin stopped working. Deploy from the command line and deploy from the local filesystem still work. Experimenting, we've determined that the failure point is somewhere between 95 - 100 MB, as in at 95MB war deploys successfully while a ...

I'm wondering what techniques others typically use for persisting dynamic content info for the presentation tier of their web apps. E.g. My customer wants via an admin section to change a few images on the home page. One could create a database table for this of course, but it doesn't feel quite right to me. One, caching is an issue. Two...
I am creating a site and I'm using sessions to manage the user log in status. When a user logs in, I create a session id for the user like so: $_SESSION['username'] = "username"; How can I check if a user is logged in, and if so, who it is? ...
