  • today's multi-device world for web development

    - by paul smith
    With the huge explosion of mobile devices and addition of HTML5/CSS3, there seems to be a shift towards "responsive" designs (i.e., adapting to smaller screen sizes) which seems to be achieved using CSS3's Media Queries. My question is, given the current need of adapting to both desktop and mobile, is it common practice to actually organize two versions of your website (one for desktop and one for mobile)? Or is there just one version with different css files for targeting different devices and screens? Handling just cross-browser (ie6, ff3, opera9, etc...) HTML4/5, CSS2/3 was already hard enough, but now we're expected to handle cross-device (phone, tablet, etc...) as well, so my assumption is company's would create a separate project for mobile and redirect based on the user agent, but this is just a guess.

  • function binding and the clone() function - Jquery

    - by Sam Vloeberghs
    Hi I have problems with my keyup binding when cloning an element. Here's the scenario: I have an html markup like this: <tr class="rijbasis"> <td> <input type="text" class="count" /> </td> <td> <span class="cost">10</span> </td> <td> <span class="total">10</span> </td> </tr> I'm binding an keyup function to the input element of my table row like this: $('.rijbasis input').keyup(function(){ var parent = $(this).parent().parent(); $('.total',parent).text(parseInt($('.cost',parent).text()) * parseInt($('.count',parent).val())); } I designed the function like this so I could clone the table row on a onclick event and append it to the tbody: $('.lineadd').click(function(){ $('.contract tbody').append($('.contract tbody tr:last').clone()); $('.contract tbody tr:last input').val("0"); }); This al works , but the keyup function doesnt work on the input elements of the cloned row.. Can anybody help or advice? I hope I was clear enough and I'll be surely adding details if needed to solve this problem. Greetings

  • converting GPS latitude/longitude from different formats to one format (in PHP)

    - by Dave
    Hi. i'm trying to built in support for locations in my application and i'm expecting users to be inputting gps coordinates in a variety of ways. I need to convert all of the below to: latitude - direction (N/s), degres, minutes, seconds; longitude (E/W) - degrees, minuts, seconds. Each user input will be in a single line. eg: 9.182, -39.140625 9.182 / -39.140625 9.182,-39.140625 9.182 -39.140625 21° 16' 674S[some_separator]27° 30' 318E 21 16 674S[some_separator]27 30 318E [some_separator] may be a single space as well... The final format needs to beas: latitude.direction = south latitude.degrees = 21 latitude.minutes = 16 latitude.seconds = 674 longitude.direction = east longitude.degrees = 27 longitude.minutes = 30 longitude.seconds = 318 (a) what is the simplest way of asking ordinary-non-tech users to input the GPS coordinate?s (b) how do i convert the above to the final format? any built in functions that handle these variations in data input? i've seen http://stackoverflow.com/questions/2548943/gps-format-in-php - but i need to handle a more varied input.

  • Webm videos converted with avconv not working properly

    - by user285943
    I'm converting mp4 videos to webm with the following command: avconv -i INPUT.mp4 -c:v libvpx -qmin 10 -qmax 42 -maxrate 500k -bufsize 1000k -threads 2 -c:a libvorbis OUTPUT.webm Am I doing something wrong? Should I use all of these parameters? I just want to make the videos compatible with all the browsers/devices. The videos are not working on Firefox on most devices and on Chrome in a specific Android device that I have. EDIT: When i play the embeded videos on firefox, on any android device, it goes straight to the end and doesn't play. It only plays if i click in the progress bar. If i open the videos on firefox without embedding them in a html page, they seem to have a bigger width box outside then, while the video is inside it. I uploaded a video that i converted. Try it in firefox: https://mega.co.nz/#!cg9FVZJD!CpC6X3NXH8rAVdBiS9ZqqwyITdyPb_qkKAKsvQXRpzI This is a comparison between the videos, after and before the conversion: ![Image here]: http://i.imgur.com/V2FijCQ.jpg

  • JQuery checkbox state is updated differently between group click() and $.each(obj.click())

    - by teerapap
    The code below doesn't work in the same behavior. The sequence of click event and calling foo() is different. I want to know why they behave different sequence between call click() and iterate the objects before call click() on each. <script type="text/javascript"> function foo(obj){ alert(obj.id+" ->"+obj.checked); } function clickAll(val){ if (val) { $(":checkbox").click(); } else { $(":checkbox").each(function(i,obj){ obj.click(); }); } } </script> </head> <body> <input type="checkbox" id="check1" onclick="foo(this)" /> a <input type="checkbox" id="check2" onclick="foo(this)" /> b <input type="checkbox" id="check3" onclick="foo(this)" /> c <input type="button" onclick="clickAll(true)" value="click all" /> <input type="button" onclick="clickAll(false)" value="click all each" /> </body>

  • Developing a computer system based on Nand2Tetris [on hold]

    - by Ryan
    I recently finished a book called Nand2Tetris (nand2tetris.org) where I built my own computer system from scratch with its own machine language, assembly code, and a high level language called Jack that's translated to Hack binary. However, I feel like the "computer" I built throughout the course of this book (called the Hack computer) is a bit too simple for various reasons: 1) There are only two registers (D and A), whereas most computers have much more 2) Peripheral devices like mouse and keyboard have to be directly implemented 3) Peripheral devices use a pre-planned shared memory map to communicate with the CPU instead of using interrupts (which aren't covered at all) 4) Jack (the high level language) code doesn't compile to Assembly code directly, instead it compiles to an intermediate language, which in turn gets translated to Assembly. 5) There is no ROM or permanent storage device, everything is stored in RAM 6) No support for colored monitor, networking or sound I would like to build a more complicated computer system now based on what I've learned from Nand2Tetris. Does anyone know of any good resources or books to get started on this? (BTW by computer system I mean software that can emulate the hardware of a virtual computer with its own unique instruction set)

  • UK Oracle User Group Event: Trends in Identity Management

    - by B Shashikumar
    As threat levels rise and new technologies such as cloud and mobile computing gain widespread acceptance, security is occupying more and more mindshare among IT executives. To help prepare for the rapidly changing security landscape, the Oracle UK User Group community and our partners at Enline/SENA have put together an User Group event in London on Apr 19 where you can learn more from your industry peers about upcoming trends in identity management. Here are some of the key trends in identity management and security that we predicted at the beginning of last year and look how they have turned out so far. You have to admit that we have a pretty good track record when it comes to forecasting trends in identity management and security. Threat levels will grow—and there will be more serious breaches:   We have since witnessed breaches of high value targets like RSA and Epsilon. Most organizations have not done enough to protect against insider threats. Organizations need to look for security solutions to stop user access to applications based on real-time patterns of fraud and for situations in which employees change roles or employment status within a company. Cloud computing will continue to grow—and require new security solutions: Cloud computing has since exploded into a dominant secular trend in the industry. Cloud computing continues to present many opportunities like low upfront costs, rapid deployment etc. But Cloud computing also increases policy fragmentation and reduces visibility and control. So organizations require solutions that bridge the security gap between the enterprise and cloud applications to reduce fragmentation and increase control. Mobile devices will challenge traditional security solutions: Since that time, we have witnessed proliferation of mobile devices—combined with increasing numbers of employees bringing their own devices to work (BYOD) — these trends continue to dissolve the traditional boundaries of the enterprise. This in turn, requires a holistic approach within an organization that combines strong authentication and fraud protection, externalization of entitlements, and centralized management across multiple applications—and open standards to make all that possible.  Security platforms will continue to converge: As organizations move increasingly toward vendor consolidation, security solutions are also evolving. Next-generation identity management platforms have best-of-breed features, and must also remain open and flexible to remain viable. As a result, developers need products such as the Oracle Access Management Suite in order to efficiently and reliably build identity and access management into applications—without requiring security experts. Organizations will increasingly pursue "business-centric compliance.": Privacy and security regulations have continued to increase. So businesses are increasingly look for solutions that combine strong security and compliance management tools with business ready experience for faster, lower-cost implementations.  If you'd like to hear more about the top trends in identity management and learn how to empower yourself, then join us for the Oracle UK User Group on Thu Apr 19 in London where Oracle and Enline/SENA product experts will come together to share security trends, best practices, and solutions for your business. Register Here.

  • WPF Show wait cursor before application fully loads

    - by e28Makaveli
    I want to show the wait cursor before my WPF application, composed using CAL, fully loads. In the constructor of the main window, I have the following code: public MainWindow([Dependency] IUnityContainer container) { InitializeComponent(); Cursor = System.Windows.Input.Cursors.Wait; Mouse.OverrideCursor = System.Windows.Input.Cursors.Wait; ForceCursor = true; //this.Cursor = System.Windows.Input.Cursors.AppStarting; // event subscriptions PresenterBase.EventAggregate.GetEvent<ModulesLoadedEvent>().Subscribe(OnModulesLoaded); } After all modules have been loaded, the following handler is invoked: private void OnModulesLoaded(EventArgs e) { allModulesLoaded = true; Mouse.OverrideCursor = null; Cursor = System.Windows.Input.Cursors.Arrow; } Problem is, I do not see this wait cursor. What I am missing here? FWIW, I got a hint from this post http://stackoverflow.com/questions/2078766/showing-the-wait-cursor TIA.

  • jQuery show some content on radio select

    - by I-M-JM
    Hi I have 2 radio button (i.e., <input type="radio">) with values "yes","no" Now, I need to show a 2 other fields when someone selects "yes" I understand that I need to place them in <div>, but when someone selects "yes", then div should show, with some highlight I need to achieve these 2 things (that I guess): showing up the div and highlighting it for some time (for user attention). <input type="radio" id="dl" value="YES" />Yes <input type="radio" id="dl" value="NO" checked />No <div id="dlyes"><label>Number</label><input type="text" id="dlno" /></div> Does anyone know how to achieve this?

  • MonoRail CheckboxList?

    - by Justin
    I'm trying to use a Checkboxlist in MonoRail to represent a many to many table relationship. There is a Special table, SpecialTag table, and then a SpecialTagging table which is the many to many mapping table between Special and SpecialTag. Here is an excerpt from the Special model class: [HasAndBelongsToMany(typeof(SpecialTag), Table = "SpecialTagging", ColumnKey = "SpecialId", ColumnRef = "SpecialTagId")] public IList<SpecialTag> Tags { get; set; } And then in my add/edit special view: $Form.LabelFor("special.Tags", "Tags")<br/> #set($items = $FormHelper.CreateCheckboxList("special.Tags", $specialTags)) #foreach($specialTag in $items) $items.Item("$specialTag.Id") $Form.LabelFor("$specialTag.Id", $specialTag.Name) #end The checkboxlist renders correctly, but if I select some and then click Save, it doesn't save the special/tag associations to the SpecialTagging table (the entity passed to the Save controller action has an empty Tags list.) One thing I noticed was that the name and value attributes on the checkboxes are funky: <label for="special_Tags">Tags</label><br> <input id="3" name="special.Tags[0]" value="UCampus.Core.Models.SpecialTag" type="checkbox"> <label for="3">Buy 1 Get 1 Free</label> <input id="1" name="special.Tags[1]" value="UCampus.Core.Models.SpecialTag" type="checkbox"> <label for="1">Free</label> <input id="2" name="special.Tags[2]" value="UCampus.Core.Models.SpecialTag" type="checkbox"> <label for="2">Half Price</label> <input id="5" name="special.Tags[3]" value="UCampus.Core.Models.SpecialTag" type="checkbox"> <label for="5">Live Music</label> <input id="4" name="special.Tags[4]" value="UCampus.Core.Models.SpecialTag" type="checkbox"> <label for="4">Outdoor Seating</label> Anyone have any ideas? Thanks! Justin

The two usb ports on the left work just fine. EDIT: I just updated my bios from 1.32 to 1.39, no change in behaviour. The port does not even power up my devices. EDIT 2: Booted up windows, and the port is working. I went into the device manager and looked at the USB settings. I found my USB drive on Port 2, Hub 3, i just don't know how that relates to the Bus and Device numbers of linux. In windows, Smart card reader was on USB hub located at port 1 hub 2, fingerprint and bluetooth were on USB hub located at port 1 hub 1 EDIT 3: Went and looked at this SO post. Tried to look at my kern.log file with tail -f /var/log/kern.log. Got some activity when plugging/removing devices in other ports, but nothing happens when connecting a device into that port. It really looks disabled. Looked at my usb1-4 sys/bus/usb/devices/usb1/power/control and they are all set on auto. As expected, usb4 have version 3.00, the others (usb1-usb3) are 2.00.
