  • I&rsquo;m offended by your antisemantic views

    - by Brian Schroer
    CSS class names should usually be “semantic” (describing the meaning of the styled areas, e.g. “article-title”, “author-info”, “errror-message”, not “structural” (e.g. “left-side-navbar”, “small-title”). …and they definitely shouldn’t explicitly describe the styling. I’ve seen a class names like “bold-red-12pt”. If you’re going to do that, you might as well just use inline font tags. This article explains it much better than I can…

  • Issue 56 - Super Stylesheets Skinning in DotNetNuke 5

    May 2010 Welcome to Issue 56 of DNN Creative Magazine In this issue we show you how to use the powerful new Super Stylesheets skinning feature in DotNetNuke 5. Super Stylesheets are ideal for both beginner and experienced skin designers, they provide skin layouts using CSS. The advantage of Super Stylesheets is that you can easily create a skin layout which works in all browsers without the need to learn complex CSS techniques. They are also very quick to build and you can change a skin layout in a matter of minutes rather than hours. We show you how to build a skin from the very beginning using Super Stylesheets, we show you how to create various skin layouts, as well as multi-layouts. We also show you how to style the skin, how to add tokens such as the logo, menu, login links etc. and walk you through how to create a fully working skin from scratch. Following this we continue the Open Web Studio tutorials, this month we demonstrate how to create an installable DotNetNuke PA module using OWS. This is an essential technique which allows you to package up the OWS applications that you have created and build them into an installable zip package. The zip file is then installable as a standard DotNetNuke module which means you can easily install your OWS applications on other DotNetNuke installations by simply installing them as a standard DotNetNuke module. To finish, we have part six of the "How to Build a News Application with DotNetMushroom Rapid Application Developer (RAD)" article, where we demonstrate how to create a News Carousel using RAD, JQuery and the JCarousel plugin. This issue comes complete with 15 videos. Skinning: Super Stylesheets Skinning in DotNetNuke 5 - DNN Layouts (12 videos - 98mins) Module Development Series: How to Create an Installable DotNetNuke PA Module Using OWS (3 videos - 23mins) How to Implement a News Carousel Using DotNetMushroom RAD and JQuery View issue 56 to download all of the videos in one zip file DNN Creative Magazine for DotNetNuke Web Designers Covering DotNetNuke module video reviews, video tutorials, mp3 interviews, resources and web design tips for working with DotNetNuke.

  • What shall I include in a 10 week web technologies course?

    - by Iain
    In September I will be teaching a university module on web technologies. This session will be available to 1st year (freshman) students who don't necessarily have any programming knowledge or know how the web works. In the 2nd semester I will be teaching Flash, which is my specialism, so I know exactly what I am going to teach, but in the 1st semester I will be teaching them web standards technologies - HTML, CSS, JS, jQuery, PHP and MySQL. Where I need advice is how to proportion the emphasis for each part, and which parts of each technology to cover. Another real issue I'm struggling with is how much of the bad old ways should I teach them? Do they need to know about bold as well as strong, etc. UPDATE: based, on your feedback I will only be teaching the latest version of everything - CSS3, HTML5 etc. I'm not sure exactly how long the semester will be but I'm guessing about 10-12 weeks. Each session is a 2 hour lab. Obviously there's only so much I can cover in that time and it will be up to the students to go a research this stuff properly on W3 schools etc. My ideas so far were: Lesson 0 - Course intro and overview of the current tech landscape. What is out there, what will we be learning, what won't we. What is a web server, URL etc. Looking at different example websites and discussing how they work. Lesson 1 - HTML basics (head, body, title, img, table, a, lists, h1, strong etc) Lesson 2 - CSS for styling and layout - fonts, webfonts, float etc Lesson 3 - Intro to programming JS (variables, loops, conditionals, functions) Lesson 4 - more JS programming fundamentals, DOM manipulation Lesson 5 - jQuery - making things fly about and look cool Lesson 6 - XML and Ajax Lesson 7 - PHP basics - syntax, server-side principles Lesson 8 - PHP and MySQL - forms, logins, saving user info Lesson 9 - don't know Lesson 10 - don't know Please let me know if you think this is the right order, what have I missed, how to use any spare sessions etc. Thanks :) UPDATE BASED ON RESPONSES: Thanks for all your responses - some great stuff. To be absolutely clear, this is not a computer science course, it is a practical module on a creative technology course. The emphasis definitely has to be on making cool things work rather than understanding how the backbone of the internet works. That can come later, if the students are interested. At the end of the module I would like the students to be able to produce a web page or pages that does something cool, using some or all of the technologies I cover. Many of these topics are of course far beyond the scope of a 2 hour session, however I do not have the option of reducing the syllabus, I will just have to explain what the technology does and encourage the student to research it in their own time.

  • Where should instantiated classes be stored?

    - by Eric C.
    I'm having a bit of a design dilemma here. I'm writing a library that consists of a bunch of template classes that are designed to be used as a base for creating content. For example: public class Template { public string Name {get; set;} public string Description {get; set;} public string Attribute1 {get; set;} public string Attribute2 {get; set;} public Template() { //constructor } public void DoSomething() { //does something } ... } The problem is, not only is the library providing the templates, it will also supply quite a few predefined templates which are instances of these template classes. The question is, where do I put these instances of the templates? The three solutions I've come up with so far are: 1) Provide serialized instances of the templates as files. On the one hand, this solution would keep the instances separated from the library itself, which is nice, but it would also potentially add complexity for the user. Even if we provided methods for loading/deserializing the files, they'd still have to deal with a bunch of files, and some kind of config file so the app knows where to look for those files. Plus, creating the template files would probably require a separate app, so if the user wanted to stick with the files method of storing templates, we'd have to provide some kind of app for creating the template files. Also, this requires external dependencies for testing the templates in the user's code. 2) Add readonly instances to the template class Example: public class Template { public string Name {get; set;} public string Description {get; set;} public string Attribute1 {get; set;} public string Attribute2 {get; set;} public Template PredefinedTemplate { get { Template templateInstance = new Template(); templateInstance.Name = "Some Name"; templateInstance.Description = "A description"; ... return templateInstance; } } public Template() { //constructor } public void DoSomething() { //does something } ... } This method would be convenient for users, as they would be able to access the predefined templates in code directly, and would be able to unit test code that used them. The drawback here is that the predefined templates pollute the Template type namespace with a bunch of extra stuff. I suppose I could put the predefined templates in a different namespace to get around this drawback. The only other problem with this approach is that I'd have to basically duplicate all the namespaces in the library in the predefined namespace (e.g. Templates.SubTemplates and Predefined.Templates.SubTemplates) which would be a pain, and would also make refactoring more difficult. 3) Make the templates abstract classes and make the predefined templates inherit from those classes. For example: public abstract class Template { public string Name {get; set;} public string Description {get; set;} public string Attribute1 {get; set;} public string Attribute2 {get; set;} public Template() { //constructor } public void DoSomething() { //does something } ... } and public class PredefinedTemplate : Template { public PredefinedTemplate() { this.Name = "Some Name"; this.Description = "A description"; this.Attribute1 = "Some Value"; ... } } This solution is pretty similar to #2, but it ends up creating a lot of classes that don't really do anything (none of our predefined templates are currently overriding behavior), and don't have any methods, so I'm not sure how good a practice this is. Has anyone else had any experience with something like this? Is there a best practice of some kind, or a different/better approach that I haven't thought of? I'm kind of banging my head against a wall trying to figure out the best way to go. Thanks!

  • Leveraging a hosted web font service from a local development server?

    - by Tom Auger
    There are a number of popular web font services on the market today who "host" the fonts and serve them to your web page via javascript or CSS pointing to remote locations. For example http://webfonts.fonts.com or http://typekit.com However, there seems to be an issue when you're developing on a local testing server - the remote font services don't validate the font and return 403 access denied errors and the like. What workarounds are there for using remote services such as a hosted font service, on a local development server?

  • Awesome WordPress modular theme builder?

    - by Matt M.
    I came across a really neat modular theme for WordPress a while ago, but I can't remember the name so I'm wondering if somebody can help out. It was a paid theme with a dedicated company behind it if I'm not mistaken. The theme allowed you to change the colors of all the content areas, define widgets, and resize content areas. I'm really interested in being able to resize columns and such at the touch of a button, getting too old for the usual CSS micromanagement that goes on with brittle themes.

  • Styling Windows Phone Silverlight Applications

    - by Tim Murphy
    If you have not developed with styles in Silverlight/XAML then it can be challenging and resources can be sparse depending on how deep you get.  One thing that you need to understand is what level you can apply styles and how much they can cascade.  What I am finding is that this doesn’t go to the level that we are used to in HTML and CSS. While styles can be defined at a page level if you want to share styles throughout your application they should be defined in the App.xaml file.  This is of course analogous to placing a style in your HTML file versus an external CSS file.  This is the type of style I will concentrate on in this post. The first thing to look it how styles associate to elements.  TargetType defines the object type that your style will apply to.  In the example below the style is targeting the TextBlock object type. <Style x:Key="TextBlockSmallGray" TargetType="TextBlock"> Next we use a Setter which allows you to apply values for specific attributes of the target object type.  The setters can be a simple value or complex.  The first example here is simply applying a color to the background property of the target. <Setter Property="Background" Value="White"/> The second setter example here is for the same property, but we are applying a the definition of a LinearGradientBrush. <Setter Property="Background"> <Setter.Value> <LinearGradientBrush> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset="1" Color="White"/> </LinearGradientBrush> </Setter.Value> </Setter> The last thing I want to cover here is that you can leverage the system styles and then override or extend them.  The BasedOn attribute of the Style tag allows this sort of inheritance.  In the example below I am going to start with the PhoneTextTitleStyle and then override properties as needed. <Style x:Key="TextBlockTitle" BasedOn="{StaticResource PhoneTextTitle1Style}" TargetType="TextBlock"> So now that we have our styles defined applying it is fairly straight forward.  Add the style name as a static resource to the style property of the element in your page and off you go. <Grid x:Name="LayoutRoot" Style="{StaticResource PageGridStyle}"> So this is one step in creating consistency in your application’s look.  In future posts I will dig a little deeper. del.icio.us Tags: windows phone 7,mobile development,windows phone 7 development,.NET,software development,design,UX

  • Two bugs you should be aware of

    - by AaronBertrand
    In the past 24 hours I have come across two bugs that can be quite problematic in certain environments. LPIM issue with SetFileIoOverlappedRange Last night the CSS team posted a blog entry detailing a potential issue with Lock Pages in Memory and Windows' SetFileIoOverlappedRange API. I tweeted about it at the time, but thought it could use a little more treatment. The potential symptoms can vary, but include the following (as quoted from the blog post): Wide ranging in SQL from invalid write location,...(read more)

  • What do you do when working with multiple languages with different capitalization schemes?

    - by dvcolgan
    I'm making a webapp using Django. The Python convention for naming variables is lowercase_with_underscores, but the Javascript convention is camelCase. In addition, I've seen many people use lowercase-with-hyphens for CSS identifiers. Would you suggest using all three naming conventions where appropriate, or picking one and using it, even if the other two recommend something else? Switching back and forth isn't a huge problem, but it can still be mental overhead.

  • Come up with a real-world problem in which only the best solution will do (a problem from Introduction to algorithms) [closed]

    - by Mike
    EDITED (I realized that the question certainly needs a context) The problem 1.1-5 in the book of Thomas Cormen et al Introduction to algorithms is: "Come up with a real-world problem in which only the best solution will do. Then come up with one in which a solution that is “approximately” the best is good enough." I'm interested in its first statement. And (from my understanding) it is asked to name a real-world problem where only the exact solution will work as opposed to a real-world problem where good-enough solution will be ok. So what is the difference between the exact and good enough solution. Consider some physics problem for example the simulation of the fulid flow in the permeable medium. To make this simulation happen some simplyfing assumptions have to be made when deriving a mathematical model. Otherwise the model becomes at least complex and unsolvable. Virtually any particle in the universe has its influence on the fluid flow. But not all particles are equal. Those that form the permeable medium are much more influental than the ones located light years away. Then when the mathematical model needs to be solved an exact solution can rarely be found unless the mathematical model is simple enough (wich probably means the model isn't close to reality). We take an approximate numerical method and after hours of coding and days of verification come up with the program or algorithm which is a solution. And if the model and an algorithm give results close to a real problem by some degree that is good enough soultion. Its worth noting the difference between exact solution algorithm and exact computation result. When considering real-world problems and real-world computation machines I believe all physical problems solutions where any calculations are taken can not be exact because universal physical constants are represented approximately in the computer. Any numbers are represented with the limited precision, at least limited by amount of memory available to computing machine. I can imagine plenty of problems where good-enough, good to some degree solution will work, like train scheduling, automated trading, satellite orbit calculation, health care expert systems. In that cases exact solutions can't be derived due to constraints on computation time, limitations in computer memory or due to the nature of problems. I googled this question and like what this guy suggests: there're kinds of mathematical problems that need exact solutions (little note here: because the question is taken from the book "Introduction to algorithms" the term "solution" means an algorithm or a program, which in this case gives exact answer on each input). But that's probably more of theoretical interest. So I would like to narrow down the question to: What are the real-world practical problems where only the best (exact) solution algorithm or program will do (but not the good-enough solution)? There are problems like breaking of cryptographic ciphers where only exact solution matters in practice and again in practice the process of deciphering without knowing a secret should take reasonable amount of time. Returning to the original question this is the problem where good-enough (fast-enough) solution will do there's no practical need in instant crack though it's desired. So the quality of "best" can be understood in any sense: exact, fastest, requiring least memory, having minimal possible network traffic etc. And still I want this question to be theoretical if possible. In a sense that there may be example of computer X that has limited resource R of amount Y where the best solution to problem P is the one that takes not more than available Y for inputs of size N*Y. But that's the problem of finding solution for P on computer X which is... well, good enough. My final thought that we live in a world where it is required from programming solutions to practical purposes to be good enough. In rare cases really very very good but still not the best ones. Isn't it? :) If it's not can you provide an example? Or can you name any such unsolved problem of practical interest?

  • Single API Architecture

    - by user1901686
    When people refer to an architecture that involves a single service API that all clients talk to (a client can be an iPad app, etc), what is the "client" for the web app -- is it A) the web browser itself. Thus, the entire app is written in html/css/javascript and ajax calls to the service are made to fetch data and changes are made through javascript or B) you have an MVC-like stack on a server, only instead of the controllers calling to the model layer directly, they call to the service API which return models that are used to render the traditional views or C) something else?
