  • Preparing layout of web-design

    - by RPK
    I am starting design work of my first website. I know very little HTML. I don't know CSS and I am going to learn and use simultaneously. I want to know whether there is any tutorial on how to create a layout for any website. Any tips or best practices to be followed before designing starts?

  • Web Safe Area (optimal resolution) for web app design

    - by M.A.X
    I'm in the process of designing a new web app and I'm wondering for what 'web safe area' should I optimize the app layout and design. I did some investigation and thinking on my own but wanted to share this to see what the general opinion is. Here is what I found: Optimal Display Resolution: w3schools web stats seems to be the most referenced source (however they state that these are results from their site and is biased towards tech savvy users) http://www.w3counter.com/globalstats.php (aggregate data from something like 15,000 different sites that use their tracking services) StatCounter Global Stats Display Resolution (Stats are based on aggregate data collected by StatCounter on a sample exceeding 15 billion pageviews per month collected from across the StatCounter network of more than 3 million websites) NetMarketShare Screen Resolutions (marketshare.hitslink.com) (a web analytics consulting firm, they get data from browsers of site visitors to their on-demand network of live stats customers. The data is compiled from approximately 160 million visitors per month) Display Resolution Summary: There is a bit of variation between the above sources but in general as of Jan 2011 looks like 1024x768 is about 20%, while ~85% have a higher resolution of at least 1280x768 (1280x800 is the most common of these with 15-20% of total web, depending on the source; 1280x1024 and 1366x768 follow behind with 9-14% of the share). My guess would be that the higher resolution values will be even more common if we filter on North America, and even higher if we filter on N.American corporate users (unfortunately I couldn't find any free geographically filtered statistics). Another point to note is that the 1024x768 desktop user population is likely lower than the aforementioned 20%, seeing as the iPad (1024x768 native display) is likely propping up those number. My recommendation would be to optimize around the 1280x768 constraint (*note: 1280x768 is actually a relatively rare resolution, but I think it's a valid constraint range considering that 1366x768 is relatively common and 1280 is the most common horizontal resolution). Browser + OS Constraints: To further add to the constraints we have to subtract the space taken up by the browser (assuming IE, which is the most space consuming) and the OS (assuming WinXP-Win7): Win7 has the biggest taskbar footprint at a height of 40px (XP's and Vista's is 30px) The default IE8 view uses up 25px at the bottom of the screen with the status bar and a further 120px at the top of the screen with the windows title bar and the browser UI (assuming the default 'favorites' toolbar is present, it would instead be 91px without the favorites toolbar). Assuming no scrollbar, we also loose a total of 4px horizontally for the window outline. This means that we are left with 583px of vertical space and 1276px of horizontal. In other words, a Web Safe Area of 1276 x 583 Is this a correct line of thinking? I tried to Google some design best practices but most still talk about designing around 1024x768 which seems to be quickly disappearing. Any help on this would be greatly appreciated! Thanks.

  • domain specific languages and compilers

    - by hyperboreean
    I was looking over Martin Fowler's recent book contents - Domain Specific Languages and I noticed some ANTLR example - that got me thinking that writing compilers will become more and more popular since people needs in this matter will increase. So, will the compiler theory still be as arid (being subjective here) as it was until now or are there any chances that we'll get more applied, programmer oriented materials ?

  • Whois list of Top Level Domain against their corresponding registrar

    - by Daniel
    I'm trying to find a list of TLD's to their corresponding whois server, for example .com americanWhoisServer .net someOtherWhoisServer .au australianWhoisServer In the end i'm aiming for something like a Dictionary where the key is the TLD and the value is the whois server address (eg whois.apnic.net). Ah snap, i just realised that i am given the IP addresses and not domain names but a list could still come in handy. How can i determine which whois server to use given a IP address? Guess and check?

  • Receiving Error Domain=kCFErrorDomainCFNetwork Code=2 when attempting to read from ReadStream

    - by theactiveactor
    I'm attempting to synchronously read from a CFReadStream objected created by CFStreamCreatePairWithSocketToHost. The stream opened fine but when I attempt to invoke CFReadStreamRead on it in a loop, CFReadStreamRead() returns -1 and the resulting error is: Error Domain=kCFErrorDomainCFNetwork Code=2 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error 2.)" UserInfo=0x14a920 {kCFGetAddrInfoFailureKey=8} I'm also receiving this same exact error when using this ReadStream asynchronously- the first callback I receive is this error.

  • Fix for iframe calling location.href

    - by blcArmadillo
    I'm trying to embed a mapquest direction page such as http://www.mapquest.com/maps?1c=Ann+Arbor&1s=MI&1a=1440+Hubbard+St&1z=48109-2083&1y=US&1l=42.293437&1g=-83.724491&1v=ADDRESS&2c=Ann+Arbor&2s=MI&2a=930+N+University+Ave&2z=48109-1055&2y=US&2l=42.278558&2g=-83.737969&2v=ADDRESS using an iframe. The problem is at least one of their javascripts calls location.href which is causing the script to hang. If I'm not mistaken this is because the page I'm embedding the page on is in a different domain. Are there any ways around this?

  • Is it worthwhile to implement observer pattern in PHP?

    - by Extrakun
    I have been meaning to make use of design pattern in PHP, such as the observer pattern, but that I have to recreate the observers' relationship each time the page is loaded pains me. As references are saved as a new concrete objects in session, there is no way to preserve relationships between subscribers and their observers unless you use a GUID or some other properties to form a lookup, and store that property instead. With the cost of recreating the relationships each time a page is loaded, is it worthwhile to use design patterns such as observers in PHP, compared to having a clean design? Any real-world experience to share?

  • How to design tag database structure?

    - by liuxingruo
    I have a subjects database, and I want to create a new tag database to tag the subjects, but I have no idea how to design the new tag database structure. I'm assuming the new database looks like this: tag_id tag_name tagged_subject_ids 1 tag1 1, 2, 3, 5, 10 2 tag2 2, 4, 5, 6, 10, 12 so, if I want to select the tags belong to subject 1: SELECT tag_name FROM tag_database WHERE tagged_subject_ids LIKE '1'; I think the way that I select tag may be very slow, so please help me. Thanks!

  • Personal project in Java

    - by Chuck
    My first project in java is going to be a program (eventually I have to create a GUI interface but for now CLI would do) to keep track of my books (something similar to what libraries have only a simpler). I need to be able to insert, update, remove, show all books, update, search(by name or author or date). For the design I was thinking one main class Library which will have all of the above as methods that connect to the db and retrieve the data. Is this approach ok? I realize it's simple but it's my first real project and I would appreciate a little feedback. Also, is it too soon to consider reading up on design patterns and database design ?

  • best way to authenticate and consume web service using phonegap (html5/javascript)

    - by Raiss
    I am going to develop a phonegap application which is pretty simple. I need to implement an authentication and some simple data transfer back and forth to the phone and server. I prefer to use ASP.NET as a web service and our database is MS SQL but I am not sure what approach should I take to create a secure communication between Phonegap App and webservice. The problem with a simple AJAX request is limitation in cross-domain and I’m not sure if JSONP is a good option. I was wondering if someone can tell me what technology I should use in order to make a semi secure connection which works with PhoneGap (html5, javascript ) and .Net webservice. I understand that it’s a general question but I need to know what technology is the best in such a case. thanks

  • Re-designing 37signals paths to be hosted under a single domain

    37signals is a web app company. Some of their applications: basecamp, to manage projects highrise, to manage contacts backpack, like a wiki they use different domains for each application (basecamphq.com, highrisehq.com, etc) in basecamp, this is the address of a particular comment for a post in a project of my company (acme) https://acme.basecamphq.com/projects/431678/posts/2964581/comments#5854236 if 37signals had chosen to host all the applications under their domain using folders (eg 37signals.com/basecamp/..., how would you design the paths?

  • Fluid Design bugs in ie7

    - by Qwibble
    Hey guys, I've created a dummy layout for my latest design, but when I resize the window in ie7 to check that the min-width works, it kicks the content area to below the sidebar, whereas in all other browsers (including ie6) it behaves exactly as it should do. Demo Link Can anyone see what the problem is that's causing this random couple extra pixels that kick it off?

  • Applying Domain Model on top of Linq2Sql entities

    - by Thomas
    I am trying to practice the model first approach and I am putting together a domain model. My requirement is pretty simple: UserSession can have multiple ShoppingCartItems. I should start off by saying that I am going to apply the domain model interfaces to Linq2Sql generated entities (using partial classes). My requirement translates into three database tables (UserSession, Product, ShoppingCartItem where ProductId and UserSessionId are foreign keys in the ShoppingCartItem table). Linq2Sql generates these entities for me. I know I shouldn't even be dealing with the database at this point but I think it is important to mention. The aggregate root is UserSession as a ShoppingCartItem can not exist without a UserSession but I am unclear on the rest. What about Product? It is defiently an entity but should it be associated to ShoppingCartItem? Here are a few suggestion (they might all be incorrect implementations): public interface IUserSession { public Guid Id { get; set; } public IList<IShoppingCartItem> ShoppingCartItems{ get; set; } } public interface IShoppingCartItem { public Guid UserSessionId { get; set; } public int ProductId { get; set; } } Another one would be: public interface IUserSession { public Guid Id { get; set; } public IList<IShoppingCartItem> ShoppingCartItems{ get; set; } } public interface IShoppingCartItem { public Guid UserSessionId { get; set; } public IProduct Product { get; set; } } A third one is: public interface IUserSession { public Guid Id { get; set; } public IList<IShoppingCartItemColletion> ShoppingCartItems{ get; set; } } public interface IShoppingCartItemColletion { public IUserSession UserSession { get; set; } public IProduct Product { get; set; } } public interface IProduct { public int ProductId { get; set; } } I have a feeling my mind is too tightly coupled with database models and tables which is making this hard to grasp. Anyone care to decouple?

  • Make two servers talk to each other

    - by Maksim
    I have application written in GWT and hosted on Google AppEngine/Java. In this application user will have an option to upload video/audio/text file to the server. Those files could be big, up to 1gb or so and because GAE/J does not support large file I have to use another server to store those files. This would be easy to implement if there was no cross-domain security feature in browsers. So, what I'm thinking is to make GAE Server talk to my server (Glassfish or any other java servers if needed) to tell url to the file and if possible send status of uploaded file (how many percent was uploaded) so I can show status on clients screen. Here is what I'm thinking to do. When user loads GWT page that is stored on GAE/J he/she will upload file to my server, then my server will send response back to GAE and GAE will send response to the client. If this scenario is possible what would be the best way to implement GAE to Glassfish conversation?
