• What's New in Oracle VM VirtualBox 4.2?

  - by Fat Bloke

  A year is a long time in the IT industry. Since the last VirtualBox feature release, which was a little over a year ago, we've seen: new releases of cool new operating systems, such as Windows 8, ChromeOS, and Mountain Lion; we've seen a myriad of new Linux releases from big Enterprise class distributions like Oracle 6.3, to accessible desktop distros like Ubuntu 12.04 and Fedora 17; and we've also seen the spec of a typical PC or laptop double in power. All of these events have influenced our new VirtualBox version which we're releasing today. Here's how... Powerful hosts  One of the trends we've seen is that as the average host platform becomes more powerful, our users are consistently running more and more vm's. Some of our users have large libraries of vm's of various vintages, whilst others have groups of vm's that are run together as an assembly of the various tiers in a multi-tiered software solution, for example, a database tier, middleware tier, and front-ends.  So we're pleased to unveil a more powerful VirtualBox Manager to address the needs of these users: VM Groups Groups allow you to organize your VM library in a sensible way, e.g.  by platform type, by project, by version, by whatever. To create groups you can drag one VM onto another or select one or more VM's and choose Machine...Group from the menu bar. You can expand and collapse groups to save screen real estate, and you can Enter and Leave a group (think iPad navigation here) by using the right and left arrow keys when groups are selected. But groups are more than passive folders, because you can now also perform operations on groups, rather than all the individual VMs. So if you have a multi-tiered solution you can start the whole stack up with just one click. Autostart Many VirtualBox users run dedicated services in their VMs, for example, running a Wiki. With these types of VM workloads, you really want the VM start up when the host machine boots up. So with 4.2 we've introduced a cross-platform Auto-start mechanism to allow you to treat VMs as host services. Headless VM Launching With VM's such as web servers, wikis, and other types of server-class workloads, the Console of the VM is pretty much redundant. For some time now VirtualBox has offered a separate launch mechanism for these VM's, namely the command-line interface commands VBoxHeadless or VBoxManage startvm ... --type headless commands. But with 4.2 we also allow you launch headless VMs from the Manager. Simply hold down Shift when launching the VM from the Manager.  It's that easy. But how do you stop a headless VM? Well, with 4.2 we allow you to Close the VM from the Manager. (BTW best to use the ACPI Shutdown method which allows the guest VM to close down gracefully.) Easy VM Creation For our expert users, the  New VM Wizard was a little tiresome, so now there's a faster 2-click VM creation mode. Just Hide the description when creating a new VM. Powerful VMs  As the hosts have become more powerful, so are the guests that are running inside them. Here are some of the 4.2 features to accommodate them: Virtual Network Interface Cards  With 4.2, it's now possible to create VMs with up to 36 NICs, when using the ICH9 chipset emulation. But with great power comes great responsibility (didn't Obi-Wan say something similar?), and so we have also introduced bandwidth limiting to prevent a rogue VM stealing the whole pipe. VLAN tagging Some of our users leverage VLANs extensively so we've enhanced the E1000 NICs to support this.  Processor Performance If you are running a CPU which supports Nested Paging (aka EPT in the Intel world) such as most of the Core i5 and i7 CPUs, or are running an AMD Bulldozer or later, you should see some performance improvements from our work with these processors. And while we're talking Processors, we've added support for some of the more modern VIA CPUs too. Powerful Automation Because VirtualBox runs atop a fully blown operating system, it makes sense to leverage the capabilities of the host to run scripts that can drive the guest VMs. Guest Automation was introduced in a prior release but with 4.2 we've revamped the APIs to allow a richer and more powerful set of operations to be executed by the guest. Check out the IGuest APIs in the VirtualBox Programming Guide and Reference (SDK). Powerful Platforms  All the hardcore engineering that has gone into 4.2 has been done for a purpose and that is to deliver a fast and powerful engine that can run almost any x86 OS because of the integrity of the virtualization. So we're pleased to add support for these platforms: Mac OS X "Mountain Lion"  Windows 8 Windows Server 2012 Ubuntu 12.04 (“Precise Pangolin”) Fedora 17 Oracle Linux 6.3  Here's the proof: We don't have time to go into the myriad of smaller improvements such as support for burning audio CDs from a guest, bi-directional clipboard control,  drag-and-drop of files into Linux guests, etc. so we'll leave that as an exercise for the user as soon as you've downloaded from the Oracle or community site and taken a peek at the User Guide. So all in all, a pretty solid release, one that we hope you'll enjoy discovering. - FB

• CodeIgniter: Passing variables via URL - alternatives to using GET

  - by John Durrant

  I'm new to CodeIgniter and have just discovered the difficulties using the GET method of passing variables via the URL (e.g. domain.com/page.php?var1=1&var2=2). I gather that one approach is to pass the variables in the URI segments but haven't quite figured out how to do that yet as it seems to create the expectation of having a function in the controller named as the specific URI segment???? Anyway Instead of using GET I've decided to use POST by adapting a submit button (disguised as a link) with the variables in hidden input fields. I've created the following solution which seems to work fine, but am wondering whether I'm on the right track here or whether there is an easier way of passing variables via a link within CodeIgniter? I've created the following class in application/libraries/ <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class C_variables { function variables_via_link($action, $link_text, $style, $link_data) { $attributes = array('style' => 'margin:0; padding:0; display: inline;'); echo form_open($action, $attributes); $attributes = array('class' => $style, 'name' => 'link'); echo form_submit($attributes, $link_text); foreach ($link_data as $key => $value){ echo form_hidden($key, $value); } echo form_close(); } } ?> With the following CSS: /* SUBMIT BUTTON AS LINK adapted from thread: http://forums.digitalpoint.com/showthread.php?t=403667 Cross browser support (apparently). */ .submit_as_link { background: transparent; border-top: 0; border-right: 0; border-bottom: 1px solid #00F; border-left: 0; color: #00F; display: inline; margin: 0; padding: 0; cursor: hand /* Added to show hand when hovering */ } *:first-child+html .submit_as_link { /* hack needed for IE 7 */ border-bottom: 0; text-decoration: underline; } * html .submit_as_link { /* hack needed for IE 5/6 */ border-bottom: 0; text-decoration: underline; } Link then created using the following code in the VIEW: <?php $link = new C_variables; $link_data=array('var1' => 1, 'var2' => 2); $link ->variables_via_link('destination_page', 'here is a link!', 'submit_as_link', $link_data); ?> Thanks for your help...

• This page calls for XML namespace declared with prefix br but no taglibrary exists

  - by Christopher W. Allen-Poole

  I just finished the Netbeans introduction to Hibernate tutorial ( http://netbeans.org/kb/docs/web/hibernate-webapp.html#01 ) and I am getting the following error: "This page calls for XML namespace declared with prefix br but no taglibrary exists" Now, I have seen a similar question somewhere else: http://forums.sun.com/thread.jspa?threadID=5430327 but the answer is not listed there. Or, if it is, then I am clearly missing it -- line one of my index.xhtml file reads "http://www.w3.org/1999/xhtml". It also does not explain why, when I reload localhost:8080, the message disappears.

• jQuery override default validation error message display (Css) Popup/Tooltip like

  - by Phill Pafford

  I'm trying to over ride the default error message label with a div instead of a label. I have looked at this post as well and get how to do it but my limitations with CSS are haunting me. How can I display this like some of these examples: Example #1 (Dojo) - Must type invalid input to see error display Example #2 Here is some example code that overrides the error label to a div element $(document).ready(function(){ $("#myForm").validate({ rules: { "elem.1": { required: true, digits: true }, "elem.2": { required: true } }, errorElement: "div" }); }); Now I'm at a loss on the css part but here it is: div.error { position:absolute; margin-top:-21px; margin-left:150px; border:2px solid #C0C097; background-color:#fff; color:white; padding:3px; text-align:left; z-index:1; color:#333333; font:100% arial,helvetica,clean,sans-serif; font-size:15px; font-weight:bold; } UPDATE: Okay I'm using this code now but the image and the placement on the popup is larger than the border, can this be adjusted to be dynamic is height? if (element.attr('type') == 'radio' || element.attr('type') == 'checkbox') { element = element.parent(); offset = element.offset(); error.insertBefore(element) error.addClass('message'); // add a class to the wrapper error.css('position', 'absolute'); error.css('left', offset.left + element.outerWidth()); error.css('top', offset.top - (element.height() / 2)); // Not working for Radio, displays towards the bottom of the element. also need to test with checkbox } else { // Error placement for single elements offset = element.offset(); error.insertBefore(element) error.addClass('message'); // add a class to the wrapper error.css('position', 'absolute'); error.css('left', offset.left + element.outerWidth()); error.css('top', offset.top - (element.height() / 2)); } the css is the same as below (your css code) Html <span> <input type="radio" class="checkbox" value="P" id="radio_P" name="radio_group_name"/> <label for="radio_P">P</label> <input type="radio" class="checkbox" value="S" id="radio_S" name="radio_group_name"/> <label for="radio_S">S</label> </span>

• CSS3 Gradients to reproduce an 'inner glow' effect from Illustrator with border-radius applied

  - by iamfriendly

  Hello all! First post on here so please be kind :) I am in the process of trying to get my head properly around CSS3 Gradients (specifically radial ones) and in doing so I think I've set myself a relatively tough challenge. In Adobe Illustrator I have created a 'button' style which can be seen here: http://bit.ly/aePPtV (jpg image). To create this image I created a rectangle with a background colour of rgb(63,64,63) or #3F403F, then 'stylized' it to have a 15px border radius. I then applied an 'inner glow' to it with a 25% opacity, 8px blur, white from the center. Finally, I applied a 3pt white stroke on it. (I'm telling you all of this in case you wished to reproduce it, if the image above isn't sufficient.) So, my question is thus: is it possible to recreate this 'button' using CSS without the need for an image? I am aware of the 'limitations' of Internet Explorer (and for the sake of this experiment, I couldn't give a monkeys). I am also aware of the small 'bug' in webkit which incorrectly renders an element with a background colour, border-radius and a border (with a different color to the background-color) - it lets the background color bleed through on the curved corners. My best attempt so far is fairly pathetic, but for reference here is the code: section#featured footer p a { color: rgb(255,255,255); text-shadow: 1px 1px 1px rgba(0,0,0,0.6); text-decoration: none; padding: 5px 10px; border-radius: 15px; -moz-border-radius: 15px; -webkit-border-radius: 15px; border: 3px solid rgb(255,255,255); background: rgb(98,99,100); background: -moz-radial-gradient( 50% 50%, farthest-side, #626364, #545454 ); background: -webkit-gradient( radial, 50% 50%, 1px, 50% 50%, 5px, from(rgb(98,99,100)), to(rgb(84,84,84)) ); } Basically, terrible. Any hints or tips gratefully accepted and thank you very much in advance for them!

• Why do many software projects fail today?

  - by TomTom

  As long as there are software projects, the world is wondering why they fail so often. I would like to know if there is a list or something equivalent which shows how many software projects fail today. Would be nice if there would be a comparison over the last 20 - 30 years. You can also add your top reason why a software project fails. Mine is "Requirements are poor or not even existing." which includes also "No (real) customer / user involved". EDIT: It is nearly impossible to clearly define the term "fail". Let's say that fail means: The project was more than 10% over budget and time. In my opinion the 10% + / - is a good range for an offer / tender. EDIT: Until now (Feb 11) it seems that most posters agree that a fail of the project is basically a failure of the project management (whatever fail means). But IMHO it comes out, that most developers are not happy with this situation. Perhaps because not the manager get penalized when a project was not successful, but the lazy, incompetent developer teams? When I read the posts I can also hear-out that there is a big "gap" between the developer side and the managment side. The expectations (perhaps also the requirements) seem to be so different, that a project cannot be successful in the end (over time / budget; users are not happy; not all first-prio features implemented; too many bugs because developers were forced to implement in too short timeframes ...) I',m asking myself: How can we improve it? Or do we have the possibility to improve it? Everybody seems to be unsatisfied with the way it goes now. Can we close the gap between these two worlds? Should we (the developers) go on strike and fight for "high quality reqiurements" and "realistic / iteration based time shedules"? EDIT: Ralph Westphal and Stefan Lieser have founded a new "community" called: Clean-Code-Developer. The aim of the group is to bring more professionalism into software engineering. Independently if a developer has a degree or tons of years of experience you can be part of this movement. Clean Code Developers live principles like SOLID every day. A professional developer is the biggest reviewer of his own work. And he has an internal value system which helps him to improve and become better. Check it out on: Clean Code Developer EDIT: Our company is doing at the moment a thing called "Application Development and Maintenance Benchmarking". This is a service offered by IBM to get a feedback from someone external on your software engineering process quality etc. When we get the results, I will tell you more about it.

• JSF a4j:commandButton not working when 'disabled' is set

  - by Jon

  Hello, When I include a 'disabled' attribute on an a4j:commandButton, the button's action is not performed. Taking the 'disabled' attribute out causes it to work properly. I am not doing any special validation (that I'm aware of) and am not seeing any validation error messages. Here is part of my page: <t:dataTable id="myTable" var="region" value="#{MyPageBackingBean.regions}" width="100%"> ... <a4j:commandButton value="Update" action="#{region.doUpdate}" oncomplete="alert('done');" disabled="#{!empty region && region.messageEmpty}" immediate="true"/> ... </t:dataTable> Any ideas? Thanks! Edit: I tried setting preserveDataModel="true" on the t:dataTable to no avail. I also made a test having an a4j:commandButton and text box with no data table, but the backing bean action is still not being fired: <h:form> <a4j:region> <a4j:outputPanel id="testregion"> <h:messages id="messages"/> <a4j:status> <f:facet name="start"> <h:graphicImage value="/images/progress_indicator.gif"/> </f:facet> </a4j:status> <h:inputTextarea rows="5" value="#{MyPageBackingBean.myValue}" style="width:100%; border: 1px solid #99CCFF;"> <a4j:support event="onkeyup" reRender="testregion" eventsQueue="messageModificationQueue" ignoreDupResponses="true" requestDelay="500"/> </h:inputTextarea> <a4j:commandButton id="doDelete" value="Delete" action="#{MyPageBackingBean.dummy}" reRender="testregion" disabled="#{empty MyPageBackingBean.myValue}"/> <h:outputText value="#{MyPageBackingBean.myValue}"/> </a4j:outputPanel> </a4j:region> </h:form> Here is the new backing bean code used for testing: private String m_myValue = null; public String getMyValue() { return m_myValue; } public void setMyValue(String value) { m_myValue = value; } private String mystr2 = null; public String dummy() { mystr2 = "hello"; return null; } Thanks!

• Google slideshow shows a blank screen when calling from ajax

  - by ufk

  I'm having problems implementing google slideshow (http://www.google.com/uds/solutions/slideshow/index.html) to my web application by loading it using a jquery load() function. index.html: <script type="text/javascript" src="jquery-1.3.2.js"></script> <div id="moshe"></div> <script type="text/javascript"> $(document).ready(function(){ $('#moshe').load('test.html'); }); </script> test.html: <script type="text/javascript"> function load() { var samples = "http://dlc0421.googlepages.com/gfss.rss"; var options = { displayTime: 2000, transistionTime: 600, linkTarget : google.feeds.LINK_TARGET_BLANK }; new GFslideShow(samples, "slideshow", options); } google.load("feeds", "1"); google.setOnLoadCallback(load); </script> <div id="slideshow" class="gslideshow" style="width:300px;height:300px;position:relative; border: 2px solid blue">Loading...</div> When i execute the test.html, it loads the slideshow just fine. when i try to load using index.html that actually calls Jquery's $.load() function that loads the content of test.html into a specific div element, i see that the gallery is loading on that div, but when it's about to show images the entire page clears and all i have is a blank page. Any ideas ? a different version of index.html without using jquery: <script type="text/javascript"> function makeRequest(url) { var httpRequest; if (window.XMLHttpRequest) { // Mozilla, Safari, ... httpRequest = new XMLHttpRequest(); if (httpRequest.overrideMimeType) { httpRequest.overrideMimeType('text/xml'); // See note below about this line } } else if (window.ActiveXObject) { // IE try { httpRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { httpRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {} } } if (!httpRequest) { alert('Giving up :( Cannot create an XMLHTTP instance'); return false; } httpRequest.onreadystatechange = function() { alertContents(httpRequest); }; httpRequest.open('GET', url, true); httpRequest.send(''); } function alertContents(httpRequest) { if (httpRequest.readyState == 4) { if (httpRequest.status == 200) { document.getElementById('moshe').innerHTML=httpRequest.responseText; } else { alert('There was a problem with the request.'); } } } makeRequest('test.html'); </script>

• Log4r : logger inheritance, yaml configuration, alternatives ?

  - by devlearn

  Hello, I'm pretty new to ruby environments and I was looking for a nice logging framework to use it my ruby and rails applications. In my previous experiences I have successfully used log4j and log4p (the perl port) and was expecting the same level of usability (and maturity) with log4r. However I must say that there are a number of things that are not clear at all in the log4r framework. 1 Logger Inheritance The logger inheritance does not seem to be managed at all ! If I declare a logger named 'myapp' and then try to get a logger name 'myapp::engine', the lookup will end with a NameError. I would expect that the framework returns the root logger according to the naming scheme and to use the 'myapp' logger. Q1 : Of course I can work around this and manage the names by myself with a lookup method, however is there a cleaner way to do this without any extra coding ? 2 YAML configuration Second thing that confuses me is the yaml configuration. On the log4r site there are literally no information about this system, the doc links forward to missing pages, so all the info I can find about is contained in the examples directory of the gem. I was pretty confused with the fact that the yaml configuration must contain the pre_config section, and that I need to define my own levels. If I remove the pre_config secion, or replace all the “custom” levels by the standard ones ( debug, info, warn, fatal ) , the example will throw the following error : log4r/yamlconfigurator.rb:68:in `decode_yaml': Log level must be in 0..7 (ArgumentError) So there seems to be no way of using a simple file where we only declare the loggers and appenders for the framework. Q2 : I realy think that I missed something and that must be a way of providing a simple yaml conf file. Do you have any examples of such an usage ? 3 Variables substitution in XML file Q3 : The Yaml configuration system seems to provide such a feature however I was unable to find a similar feature with XML files. Any ideas ? 4 Alternatives ? I must say that I'm very disappointed by the feature level and the maturity of log4r compared to the log4j and other log4j ports. I run into this framework with a solid background of logging APIs in other languages and find myself working around in all kinds just to make 'basic things' running in a “real world application”. By that I mean a complex application composed of several gems, console/scripting apps, and a rails web front end where the configuration must be mutualized and where we make intensive usage of namespaces and inheritance. I've run several searches in order to find something more suitable or mature, but did not find anything similar. Q4 : Do you guys know any (serious) alternatives to log4r framework that could be used in a enterprise class app ? Thanks reading all of this ! I'd really appreciate any pointers, Kind Regards,

• IE7 relative/absolute positioning bug with dynamically modified page content

  - by Matthias Hryniszak

  Hi, I was wondering if there's anyone having an idea how to tackle with the following problem in IE7: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>IE7 absolute positioning bug</title> <style type="text/css"> #panel { position: relative; border: solid 1px black; } #spacer { height: 100px; } #footer { position: absolute; bottom: 0px; } </style> <script type="text/javascript"> function toggle() { var spacer = document.getElementById("spacer"); var style = "block"; if (spacer.style.display == "block" || spacer.style.display == "") { style = "none"; } spacer.style.display = style; } </script> </head> <body> <div id="panel"> <button onclick="toggle();">Click me</button> <br /><br /><br /> <div id="spacer"></div> <div id="footer">This is some footer</div> </div> </body> </html> When you run this in IE7 you'll see that the "footer" element stays after modifying the CSS for "panel". The same example tested in IE8, FF and Chrome behaves exactly as expected. I've already tried updating the element's class but this does not work if the browser's window has been opened maximized and no further size changes were made to the window (which is about 90% of the use cases we have for our product.... :( ) I'm stuck with a CSS-based solution however I think that I can make an exception in this case if it can easily be made IE7-specific (which means that other browsers will behave in a standard way with this). Please help!

• Difference in css-positioning in windows and linux

  - by andrii

  I have a problem with rendering my html page by the same browsers in different OS. There are 3 spans and position of each span is corrected through css(position:relative). But I have found out that the page that looks correct in firefox under Linux, shows not right at the same firefox(3.5.7) under Windows OS. Linux(Left - How it should be)/Windows(right): link text And the same with other browsers. What is the cause of this problem and how is possible to solve it. My code: question.html: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> <title>Question</title> <link href="css/question.css" rel="stylesheet" media="all" /> </head> <body> <div class="eventFullDate"> <span class="eventYear">2010</span> <span class="eventDate">17</span> <span class="eventMonth">FEB</span> </div> </body> </html> question.css: html, body{ font-family: Georgia; } div.eventFullDate{ height: 39px; width: 31px; float: left; border: 1px solid; border-color: #E3E3E3; background-color: #F7FFFF; } span.eventYear, span.eventDate, span.eventMonth{ color: #EC5C1D; position: relative; width: 100%; } span.eventYear{ left: 1px; bottom: 3px; font-size: 0.8em; } span.eventDate{ left: 5px; bottom: 12px; font-size: 1.3em; } span.eventMonth{ left: 3px; bottom: 15px; font-size: 0.8em; }

• click events issue in jquery.

  - by alex

  I don't know if the title explain this situation well. Below is a code i wrote to create div elements when the button is pressed. Then By clicking on any of the created divs, we can change the div background by choosing a color from the drop down box. However if i click on another div and tried to change the color by selecting another color from the drop down, the previously clicked divs also gets affected by the new color. Why is this happening. I only want the selected div to change color, without affecting the previously clicked divs. I read allot of threads on this site, some of which talks about unbinding clicks, but I'm unable to solve the problem. Thanks for the help. <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script> <style> .aaa { width:100px; height:100px;background-color:#ccc;margin-bottom:5px;} p{widht:500px; height:500px; margin:0px; padding:0px;border:2px solid red;color:#000;} </style> <select id="item_select" name="item"> <option value="1">red</option> <option value="2">blue</option> <option value="3">green</option> </select> <button>Click to create divs</button> <p id="ptest"></p> <script type="text/javascript"> var dividcount = 1; $("button").click(run); function run(){ var myDiv = $('<div id=lar'+dividcount+' class=aaa></div>'); $(myDiv).clone().appendTo('#ptest'); $(dividcount++); $("div").bind('click',(function() { var box = $("div").index(this); var idd = (this.id); $("#"+idd).text("div #"+idd); $("select").change(function(){ var str= $("select option:selected").text(); $("#"+idd).css("background-color",str); }); })); }; </script>

• Android Marketplace Error: "The server could not process your apk. Try again."

  - by jdandrea

  I have an updated apk - tested successfully on various devices and simulator instances - with the following manifest: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.myCompany.appName" android:versionCode="2" android:versionName="1.0.1"> <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="5" /> <uses-permission android:name="android.permission.INTERNET" /> <supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="true" /> <application android:icon="@drawable/icon" android:label="@string/icon_name" android:debuggable="false"> <activity android:name=".myActivity" android:configChanges="keyboardHidden|orientation"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> When I post to Android Marketplace as an upgrade to my existing 1.0 app, I get the aforementioned ambiguous message: "The server could not process your apk. Try again." I've searched elsewhere for this message in hopes of finding out what might be happening, to no avail. (A popular suggestion is to move the uses-sdk element to the top of the manifest, but as you can see it's already at the top.) Clues welcome/appreciated. Update: I just tried to upload the same file again. Now I get a new message: The new apk's versionCode (2) in AndroidManifest.xml must be higher than the old apk's versionCode (2). The server could not process your apk. Try again. Soooo Marketplace did get my upgraded apk after all? (The very first accepted apk's versionCode was 1, so this update was of course bumped to 2.) Confused … Bumping it up to 3 and trying again. Surprise surprise, I get the original "could not process" error all over again. Going in circles. Hmm ... :( Nuther Update: If I exit and re-enter the Marketplace page, now it shows that the app has been uploaded! Except there's no app icon. Curiouser and curiouser ... and this is all happening with a cache-cleared (standards-friendly) browser to boot. So - do I trust the upload? Or start over ... with versionCode="4"? All I want is to get a solid "Upload successful, here's the icon, ready to publish" type of response.

• Crawling engine architecture - Java/ Perl integration

  - by Bigtwinz

  Hi all, I am looking to develop a management and administration solution around our webcrawling perl scripts. Basically, right now our scripts are saved in SVN and are manually kicked off by SysAdmin/devs etc. Everytime we need to retrieve data from new sources we have to create a ticket with business instructions and goals. As you can imagine, not an optimal solution. There are 3 consistent themes with this system: the retrieval of data has a "conceptual structure" for lack of a better phrase i.e. the retrieval of information follows a particular path we are only looking for very specific information so we dont have to really worry about extensive crawling for awhile (think thousands-tens of thousands of pages vs millions) crawls are url-based instead of site-based. As I enhance this alpha version to a more production-level beta I am looking to add automation and management of the retrieval of data. Additionally our other systems are Java (which I'm more proficient in) and I'd like to compartmentalize the perl aspects so we dont have to lean heavily on outside help. I've evaluated the usual suspects Nutch, Droid etc but the time spent on modifying those frameworks to suit our specific information retrieval cant be justified. So I'd like your thoughts regarding the following architecture. I want to create a solution which use Java as the interface for managing and execution of the perl scripts use Java for configuration and data access stick with perl for retrieval An example use case would be a data analyst delivers us a requirement for crawling perl developer creates the required script and uses this webapp to submit the script (which gets saved to the filesystem) the script gets kicked off from the webapp with specific parameters .... Webapp should be able to create multiple threads of the perl script to initiate multiple crawlers. So questions are what do you think how solid is integration between Java and Perl specifically from calling perl from java has someone used such a system which actually is part perl repository The goal really is to not have a whole bunch of unorganized perl scripts and put some management and organization on our information retrieval. Also, I know I can use perl do do the web part of what we want - but as I mentioned before - trying to keep perl focused. But it seems assbackwards I'm not adverse to making it an all perl solution. Open to any all suggestions and opinions. Thanks

• Get UiBinder widget to display inline instead of block

  - by Steve Armstrong

  I'm trying to get my UiBinder-defined widget to display inline, but I can't. My current code is: <ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' xmlns:g='urn:import:com.google.gwt.user.client.ui'> <ui:style> .section { border: 1px solid #000000; width: 330px; padding: 5px; display: run-in; } </ui:style> <g:HTMLPanel> <div class="{style.section}"> <div ui:field="titleSpan" class="{style.title}" /> <div class="{style.contents}"> <g:VerticalPanel ui:field="messagesPanel" /> </div> </div> </g:HTMLPanel> </ui:UiBinder> This works fine in terms of how the widget looks internally, but I want to throw a bunch of these widgets into a FlowPanel and have them flow when the window is resized. The HTMLPanel is a div, but I can't get the display attribute to assign. I can't force the style name, since the following throws an error: <g:HTMLPanel styleNames="{style.section}"> And I can assign an additional style, but it doesn't apply the display setting. <g:HTMLPanel addStyleNames="{style.section}"> This displays the border and sets the size, as expected, but it doesn't flow. Firebug shows the styles on the div are border, width, and padding, but no display. Is there a way to make a widget in UiBinder so that it'll display inline instead of block? And if so, can I make it compatible with having a VerticalPanel inside (can I do it without making the entire widget pure HTML without any GWT widgets)? PS: I saw question 2257924 but it hasn't had any answers lately, and he seems to be focused on getting a tag, not specifically getting inline layout. I don't care directly about , if I can just get the top-level tag for my widget to flow inline, I'm happy.

• Node.js + Express.js. How to RENDER less css?

  - by Paden

  Hello all, I am unable to render less css in my express workspace. Here is my current configuration (my css/less files go in 'public/stylo/'): app.configure(function() { app.set('views' , __dirname + '/views' ); app.set('partials' , __dirname + '/views/partials'); app.set('view engine', 'jade' ); app.use(express.bodyDecoder() ); app.use(express.methodOverride()); app.use(express.compiler({ src: __dirname + '/public/stylo', enable: ['less']})); app.use(app.router); app.use(express.staticProvider(__dirname + '/public')); }); Here is my main.jade file: !!! html(lang="en") head title Yea a title link(rel="stylesheet", type="text/css", href="/stylo/main.less") link(rel="stylesheet", href="http://fonts.googleapis.com/cssfamily=Droid+Sans|Droid+Sans+Mono|Ubuntu|Droid+Serif") script(src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js") script(src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/jquery-ui.min.js") body!= body here is my main.less css: @import "goodies.css"; body { .googleFont; background-color : #000000; padding : 20px; margin : 0px; > .header { border-bottom : 1px solid #BBB; background-color : #f0f0f0; margin : -25px -25px 30px -25px; /* important */ color : #333; padding : 15px; font-size : 18pt; } } AND here is my goodies.less css: .rounded_corners(@radius: 10px) { -moz-border-radius : @radius; -webkit-border-radius: @radius; border-radius : @radius; } .shadows(@rad1: 0px, @rad2: 1px, @rad3: 3px, @color: #999) { -webkit-box-shadow : @rad1 @rad2 @rad3 @color; -moz-box-shadow : @rad1 @rad2 @rad3 @color; box-shadow : @rad1 @rad2 @rad3 @color; } .gradient (@type: linear, @pos1: left top, @pos2: left bottom, @color1: #f5f5f5, @color2: #ececec) { background-image : -webkit-gradient(@type, @pos1, @pos2, from(@color1), to(@color2)); background-image : -moz-linear-gradient(@color1, @color2); } .googleFont { font-family : 'Droid Serif'; } Cool deal. Now: I have installed less via npm and I had heard from another post that @imports should reference the .css not the .less. In any case, I have tried the combinations of switching .less for .css in the jade and less files with no success. If you can help or have the solution I'd greatly appreciate it. Note: The jade portion works fine if I enter any ol' .css. Note2: The less compiles if I use lessc via command line.

I sort of lost interest in writing code about 4-5 years ago for two reasons; Spent all day writing ASP & SQL for someone else. PC Techniques magazine went away. I've got a few programs in the shareware market that are solid performers but are in need of serious updating. I love Delphi or did when it was Borland (before Borland bought DBase and all the other crap), I'd like to salvage as much of my D5E code as possible but I doubt I can. I plan on upgrading to Delphi 2010. My next software release needs to interact with a database. I'm very proficient with MS Sql and like to put all of the database code in stored procedures. What is the best database choice that interacts well with Delphi, allows stored procedures and is so easy to deploy that even the Geico gecko could deploy it? 10/25/2009 18:53 PM EST Re-Opened After Reading Install Docs for Delphi 2010 I downloaded a trial version of Delphi 2010 and unzipped the install. I've been reading the install docs included in the package. I started with the install.htm inside the zip package. install.htm wisely tells you to see the following two articles: Installation Notes: http://edn.embarcadero.com/article/39754 Release Notes: http://edn.embarcadero.com/article/39758 the release notes state the following... MSSQL driver requires the installation of the SQL Native Client. SQL Native Client 2008 is required for dbxmss.dll. SQL Native Client 2005 is required for dbxmss9.dll I checked my machine to see if SQL Native Client is installed. Nope. I wasn't done reading the docs so I made a note to install SQL Native Client. I googled dbxmss.dll and dbxmss9.dll and found a very interesting thread on the Embarcadero forums. read thread here. After reading this thread and some careful thought I don't think I will be using Microsoft SQL Express. I can't rely on my customers having the right drivers installed. So, I'm back to looking for a different solution. If I'm selling a $40 product to the general masses I need to have a bulletproof solution that doesn't require my brand new customer to update their machine before my software will work.

• 100% width table cell

  - by Elvis

  Hello! I have this table layout. I want to align the whole content to the right. So i'm using one cell with width: 100%;. Usually everything looks good and nice. But there is something, which i don't understand. If the content in cell, which has colspan, becomes bigger than normal cell in this column (you can test this by clicking Click to test button), it brakes whole layout. This happens on Chrome, Safari 4 and 5, IE8, but on Opera, FF and IE7 is OK. Any ideas? <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>TEST</title> <style type="text/css"> table { width: 100%; } table td { border: 1px solid black; white-space: nowrap; } .delimiter { width: 100%; } </style> </head> <body> <table> <tr> <td><label>Row 1</label></td> <td>&nbsp;</td> <td><input type="text" value="Field 1" id="field1" size="25"></td> <td><input type="button" value="Click to test" onclick="var o = document.getElementById('field2'); o.size = o.size == 25 ? 50 : 25;"></td> <td class="delimiter">&nbsp;</td> </tr> <tr> <td><label>Row 2</label></td> <td>&nbsp;</td> <td colspan="3"><input type="text" id="field2" value="Field 2" size="25"></td> </tr> </table> </body> </html>

• CSS - margin and float property

  - by David Casillas

  1.- We have a div with static positioning. Inside we have a parragraph with a margin. The heigth of the div will be the parragraph without the margin 2.- We have a div with float:left. Inside we have a parragraph with a margin. The heigth of the div will be the parragraph plus its margin. What is the explanation of this? Here is the html code and the CSS code. And here is a link to the test site. http://prueba.davidcasillas.es/ <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="es"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> <link href="index.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="nivel1"> <div id="nivel21"> <p>Este es el primer parrafo</p> </div> <div id="nivel22"> <p>Este es el primer parrafo</p> </div> </div> </body> </html> body { margin:0; padding:0; } #nivel1 { border:solid; border-color:#333; margin:0; background-color:#0F3; margin:2em; } #nivel21 { margin:2em; float:left; background-color:#C00; } #nivel22 { margin:2em; background-color:#FC0; }

• JQuery Tooltip Plugin from Jorn

  - by Jeff Ancel

  I am thinking someone may have run across this one, but not sure. From a high level, I am trying to roll over a input [type=text] and display a tool tip (with the contained value) using the plugin available at http://bassitance.de. I have to use titles and classes for validation on the specific elements, so I put a blank div to hold the input [type=text] value for the roll over. Issue: It won't hold the value of 2 text boxes at once. Once I put a value in the box on the right, the tooltip on the left goes away. Same thing if I switch it aroun. I can't keep a tooltip on more than one element. Here is the code (Note: You will have to download the plugins in the source as I am not sure where the live versions are if there are any). <link rel="stylesheet" href="/scripts/jquery-tooltip/jquery.tooltip.css" /> <script type="text/javascript" src="/scripts/jquery-1.3.2.min.js"></script> <script type="text/javascript" src="/scripts/jquery-tooltip/jquery.tooltip.min.js"></script> <script type="text/javascript"> $(function(){ $("input").change(function(){ var newTitle = $(this).val(); $(this).parent().attr("title",newTitle); // re-init tool tip reload(); }); // Init tooltip reload(); }); reload = function(){ $("div").tooltip(); } </script> <body> <table border="1px solid black"> <tr> <td title="hello"> <div> <input type="text" value=""/> </div> </td> <td> <div> <input type="text" value=""/> </div> </td> </tr> </table> <div id="debug"></div> </body> </html>

• How can we implement change notification propagation for WPF and SL in the MVVM pattern?

  - by Firoso

  Here's an example scenario targetting MVVM WPF/SL development: View data binds to view model Property "Target" "Target" exposes a field of an object called "data" that exists in the local application model, called "Original" when "Original" changes, it should raise notification to the view model and then propogate that change notification to the View. Here are the solutions I've come up with, but I don't like any of them all that much. I'm looking for other ideas, by the time we come up with something rock solid I'm certain Microsoft will have released .NET 5 with WPF/SL extensions for better tools for MVVM development. For now the question is, "What have you done to solve this problem and how has it worked out for you?" Option 1. Proposal: Attach a handler to data's PropertyChanged event that watches for string values of properties it cares about that might have changed, and raises the appropriate notification. Why I don't like it: Changes don't bubble naturally, objects must be explicitly watched, if data changes to a new source, events must be un-registered/registered. Why I kind of like it: I get explicit control over propogation of changes, and I don't have to use any types that belong at a higher level of the application such as dependancy properties. Option 2. Proposal: Attach a handler to data's PropertyChanged event that re-raises the event across all properties using the name property name. Why I don't like it: This is essentially the same as option 1, but less intelligent, and forces me to never change my property names, as they have to be the same as the property names on data Why I kind of like it: It's very easy to set up and I don't have to think about it... Then again if I try to think, and change names to things that make sense, I shoot myself in the foot, and then I have to think about it! Option 3. Proposal: Inherit my view model from dependancy object, and notify binding sources of changes directly. Why I don't like it: I'm not even 100% sure dependancy properties/objects can DO this, it was just a thought to look into. Also I don't personally feel that WPF/SL types like Dep Obj belong at the view model level. Why I kind of like it: IF it has the capability that I'm seeking then it's a good answer! minus that pesky layering issue. Option 4. Proposal: Use a consistant agent messaging system based off of Task Parallels DataFlow Library to propogate everything through linked pipelining. Why I don't like it: I've never tried this, and somehow I think it will be lacking, plus it requires me to think about my code completely differently all the way around. Why I kind of like it: It has the possiblity of allowing me to do some VERY fun manipulations with a push based data model and using ActionBlocks as validation AND setters to then privately change view model properties and explicitly control PropertyChanged notifications.

• iPhone MailComposer class UIViewController dismissModalViewControllerAnimated issues

  - by Scott Pendleton

  I created a class to launch the MailComposer so that my iPhone app would only have one place to go when generating various kinds of e-mail: some with attachments, some not. Some with pre-filled addresses, some not. I didn't want my class implement UIViewController, but it has to so it can be the delegate for the MailComposer. Otherwise, the view controllers that call my class would themselves have to be delegates for the MailComposer, which defeats the purpose. The downside of having my class be a view controller is that it has to load to the screen before it can modally bring up the MailComposer. Unfortunately, view controllers can't be transparent. The effect is, whatever is on screen gets covered by a solid white view controller for a moment before the MailComposer appears. I could maybe live with that, but not this: after the MailComposer goes away, I'm left with my blank view controller occupying the screen. I ought to be able to get rid of it from within itself by calling this: [self.parentViewController dismissModalViewControllerAnimated:NO]; But that dies a horrible death: "Loading 43365 stack frames..." Has my class -- a UIViewController that pre-fills and then launches a MailComposer -- lost track of its parentViewController? It isn't nil, because I've tested for that. As launched from within the current view controller... // My class is called Email. Email *oEmail = [[[Email alloc] init] retain]; // Red, to remind myself that I'd like to someday learn to make it transparent. oEmail.view.backgroundColor = [UIColor redColor]; // Pre-fill whatever fields you want, and specify attachments. oEmail.EmailSubject = @"I am truly stumped"; // This has to go on screen first. [self presentModalViewController:oEmail animated:NO]; // Then this can happen, which brings up the MailComposer. [oEmail f_SendEmail]; // Commenting out the next line didn't help, so I turned it back on. [oEmail release]; Inside the class, you need the mailComposeController:didFinishWithResult:error: method to make the MailComposer go away, and for that to happen, the class has to be the MFMailComposeViewControllerDelegate. Here's what happens in there: // This gets rid of the mail composer. [self dismissModalViewControllerAnimated:YES]; // This never fails to get rid of other modal view controllers when called // from within those controllers, but boy does it not work here. [self.parentViewController dismissModalViewControllerAnimated:NO]; If you can help me, I will be truly thankful!

• Flex: Create custom stroke on LineSeries?

  - by John Isaacks

  You can easily set a stroke on a line series like this: <mx:LineSeries yField="apple"> <mx:lineStroke> <mx:Stroke color="0x6699FF" weight="4" alpha=".8" /> </mx:lineStroke> </mx:LineSeries> This will set alpha for the entire stroke to .8 But I want to be able to set a different alpha on the stoke for each plot based on something in the dataProvider. For example the yField in the lineSeries is "Apple" which is how it knows where to plot for the lineSeries. I want to be able to add something like alphaField which tells it what to set the stroke alpha for each plot. so if my dataProvider was: <result month="Jan-04"> <apple>81768</apple> <alpha>1</alpha> </result> <result month="Feb-04"> <apple>51156</apple> <alpha>1</alpha> </result> <result month="Mar-04"> <apple>51156</apple> <alpha>.5</alpha> </result> And I set alphaField="alpha" then I would have a solid stroke from plot 0 to plot 1 and then a 50% alpha stroke from plot 1 to plot 2. How can I do this??? I am looking in the commitProperties() and updateDisplayList() methods of LineSeries and have no idea what would need to be added/changed to make this? I am pretty sure, this class has to use Graphics.lineTo() to draw each plot, so basically it would need to "get" the current alphaField value somehow, and apply a Graphics.lineStyle() with the correct alpha before drawing each line. Thanks!! UPDATE I have gotten much closer to my answer. When I extend LineRenderer I override updateDisplayList() which calls GraphicsUtilities.drawPolyLine() I extend GraphicsUtilities and override the method drawPolyLine() as this is where the line is actually drawn. I can call lineStyle() in here and change the alpha of the line... I still have 1 thing I cannot figure out, from within the drawPolyLine() method how can I access that data that dictates what the alpha should be? Thanks!!!!
