• Atheros AR2413 wireless not working after shutdown

  - by Chandrasekhar

  I am using a Ubuntu 11.04 on an Acer aspire 3680 laptop and my wifi is not working. I followed the below commands to install the madwifi driver: sudo su apt-get install subversion cd /usr/src svn checkout http://madwifi-project.org/svn/madwifi/trunk madwifi tar cfvz madwifi.tgz cd madwifi make && make install echo "blacklist ath5k" /etc/modprobe.d/blacklist.conf echo "ath_pci" /etc/modules modprobe ath_pci sudo reboot After installation I am facing the same problem. My wifi wont work after I shutdown. Infact it didn't work after suspend but I rectified that problem by the following commands: Command 1: sudo rmmod -f ath_pci sudo rfkill unblock all sudo modprobe ath_pci along with the command SUSPEND_MODULES=ath_pci added to the /etc/pm/config.d/madwifi directory. So if I suspend and then on my laptop the wifi loads well and doesn't create a problem. But if I shutdown my laptop the wifi never loads again and eachtime I have to run a Ubuntu 9.04 live CD to load it. I did try adding the Command 1 to the /etc/rc.local directory but still it doesn't work. So my question is: What should I do in order to make my wireless work without having to run a live CD of ubuntu 9.04 everytime after shutdown? Thanks.

• "Guiding" a Domain Expert to Retire from Programming

  - by James Kolpack

  I've got a friend who does IT at a local non-profit where they're using a custom web application which is no longer supported by the company who built it. (out of business, support was too expensive, I'm not sure...) Development on this app started around 10+ years ago so the technologies being harnessed are pretty out of date now - classic asp using vbscript and SQL Server 2000. The application domain is in the realm of government bookkeeping - so even though the development team is long gone, there are often new requirements of this software. Enter the... The domain expert. This is an middle aged accounting whiz without much (or any?) prior development experience. He studied the pages, code and queries and learned how to ape the style of the original team which, believe me, is mediocre at best. He's very clever and very tenacious but has no experience in software beyond what he's picked up from this app. Otherwise, he's a pleasant guy to talk to and definitely knows his domain. My friend in IT, and probably his superiors in the company, want him out of the code. They view him as wasting his expertise on coding tasks he shouldn't be doing. My friend got me involved with a few small contracts which I handled without much problem - other than somewhat of a communication barrier with the domain expert. He explained the requirements very quickly, assuming prior knowledge of the domain which I do not have. This is partially his normal style, and I think maybe a bit of resentment from my involvement. So, I think he feels like the owner of the code and has entrenched himself in a development position. So... his coding technique. One of his latest endeavors was to make a page that only he could reach (theoretically - the security model for the system is wretched) where he can enter a raw SQL query, run it, and save the query to run again later. A report that I worked on had been originally implemented by him using 6 distinct queries, 3 or 4 temp tables to coordinate the data between the queries, and the final result obtained by importing the data from the final query into Access and doing a pivot and some formatting. It worked - well, some of the results were incorrect - but at what a cost! (I implemented the report in a single query with at least 1/10th the amount of code.) He edits code in notepad. He doesn't seem to know about online reference material for the languages. I recently read an article on Dr. Dobbs titled "What Makes Bad Programmers Different" - and instantly thought of our domain expert. From the article: Their code is large, messy, and bug laden. They have very superficial knowledge of their problem domain and their tools. Their code has a lot of copy/paste and they have very little interest in techniques that reduce it. The fail to account for edge cases, while inefficiently dealing with the general case. They never have time to comment their code or break it into smaller pieces. Empirical evidence plays no little role in their decisions. 5.5 out of 6. My friend is wanting me to argue the case to their management - specifically, I got this email from their manager to respond to: ...Also, I need to talk to you about what effect there is from Domain Expert continuing to make edits to the live environment. If that is a problem for you I need to know so I can have his access blocked. Some examples would help. In my opinion, from a technical standpoint, it's dangerous to have him making changes without any oversight. On the other hand, I'm just doing one-off contracts at this point and don't have much desire to get involved deeply enough that I'm essentially arguing as one of the Bobs from Office Space. I'd like to help my friend out - but I feel like I'm getting in the middle of a political battle. More importantly - if I do get involved and suggest that his editing privileges be removed, it needs to be handled carefully so that doesn't feel belittled. He is beyond a doubt the foremost expert on this system. I'm hoping this is familiar territory for some other stackechangers, because I'm feeling a little bewildered. How should I respond? Should I argue that he shouldn't be allowed to touch the code? Should I phrase it as "no single developer, no matter how experienced, should be working on production code unchecked"? Should I argue to keep him involved with the code, but with a review process? Should I say "glad I could help, but uh, I'm busy now!" Other options? Thanks a bunch!

• Microsoft Sql Server 2008 R2 System Databases

  For a majority of software developers little time is spent understanding the inner workings of the database management systems (DBMS) they use to store data for their applications.  I personally place myself in this grouping. In my case, I have used various versions of Microsoft’s SQL Server (2000, 2005, and 2008 R2) and just recently learned how valuable they really are when I was preparing to deliver a lecture on "SQL Server 2008 R2, System Databases". Microsoft Sql Server 2008 R2 System DatabasesSo what are system databases in MS SQL Server, and why should I know them? Microsoft uses system databases to support the SQL Server DBMS, much like a developer uses config files or database tables to support an application. These system databases individually provide specific functionality that allows MS SQL Server to function. Name Database File Log File Master master.mdf mastlog.ldf Resource mssqlsystemresource.mdf mssqlsystemresource.ldf Model model.mdf modellog.ldf MSDB msdbdata.mdf msdblog.ldf Distribution distmdl.mdf distmdl.ldf TempDB tempdb.mdf templog.ldf Master DatabaseIf you have used MS SQL Server then you should recognize the Master database especially if you used the SQL Server Management Studio (SSMS) to connect to a user created database. MS SQL Server requires the Master database in order for DBMS to start due to the information that it stores. Examples of data stored in the Master database User Logins Linked Servers Configuration information Information on User Databases Resource DatabaseHonestly, until recently I never knew this database even existed until I started to research SQL Server system databases. The reason for this is due largely to the fact that the resource database is hidden to users. In fact, the database files are stored within the Binn folder instead of the standard MS SQL Server database folder path. This database contains all system objects that can be accessed by all other databases.  In short, this database contains all system views and store procedures that appear in all other user databases regarding system information. One of the many benefits to storing system views and store procedures in a single hidden database is the fact it improves upgrading a SQL Server database; not to mention that maintenance is decreased since only one code base has to be mainlined for all of the system views and procedures. Model DatabaseThe Model database as the name implies is the model for all new databases created by users. This allows for predefining default database objects for all new databases within a MS SQL Server instance. For example, if every database created by a user needs to have an “Audit” table when it is  created then defining the “Audit” table in the model will guarantees that the table will be located in every new database create after the model is altered. MSDB DatabaseThe MSDBdatabase is used by SQL Server Agent, SQL Server Database Mail, SQL Server Service Broker, along with SQL Server. The SQL Server Agent uses this database to store job configurations and SQL job schedules along with SQL Alerts, and Operators. In addition, this database also stores all SQL job parameters along with each job’s execution history.  Finally, this database is also used to store database backup and maintenance plans as well as details pertaining to SQL Log shipping if it is being used. Distribution DatabaseThe Distribution database is only used during replication and stores meta data and history information pertaining to the act of replication data. Furthermore, when transactional replication is used this database also stores information regarding each transaction. It is important to note that replication is not turned on by default in MS SQL Server and that the distribution database is hidden from SSMS. Tempdb DatabaseThe Tempdb as the name implies is used to store temporary data and data objects. Examples of this include temp tables and temp store procedures. It is important to note that when using this database all data and data objects are cleared from this database when SQL Server restarts. This database is also used by SQL Server when it is performing some internal operations. Typically, SQL Server uses this database for the purpose of large sort and index operations. Finally, this database is used to store row versions if row versioning or snapsot isolation transactions are being used by SQL Server. Additionally, I would love to hear from others about their experiences using system databases, tables, and objects in a real world environments.

• Architecture - 32-bit handling 64-bit instructions

  - by tkoomzaaskz

  tomasz@tomasz-lenovo-ideapad-Y530:~$ lscpu Architecture: i686 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 2 On-line CPU(s) list: 0,1 Thread(s) per core: 1 Core(s) per socket: 2 Socket(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 23 Stepping: 6 CPU MHz: 2000.000 BogoMIPS: 4000.12 Cache L1d: 32K Cache L1i: 32K Cache L2: 3072K I can see that my architecture is 32-bit (i686). But CPU op-mode(s) are 32-bit and 64-bit. The question is: how come? How is it handled that a 32-bit processor performs 64-bit operations? I guess it's a lot slower than native 32-bit operations. Is it built-in processor functionality (to emulate being 64-bit) or is it software dependent? When does it make sense for a 32-bit processor to run 64-bit operations?

• Why are only some of my objects being rendered?

• BIP 11g Dynamic SQL

  - by Tim Dexter

  Back in the 10g release, if you wanted something beyond the standard query for your report extract; you needed to break out your favorite text editor. You gotta love 'vi' and hate emacs, am I right? And get to building a data template, they were/are lovely to write, such fun ... not! Its not fun writing them by hand but, you do get to do some cool stuff around the data extract including dynamic SQL. By that I mean the ability to add content dynamically to your your query at runtime. With 11g, we spoiled you with a visual builder, no more vi or notepad sessions, a friendly drag and drop interface allowing you to build hierarchical data sets, calculated columns, summary columns, etc. You can still create the dynamic SQL statements, its not so well documented right now, in lieu of doc updates here's the skinny. If you check out the 10g process to create dynamic sql in the docs. You need to create a data trigger function where you assign the dynamic sql to a global variable that's matched in your report SQL. In 11g, the process is really the same, BI Publisher just provides a bit more help to define what trigger code needs to be called. You still need to create the function and place it inside a package in the db. Here's a simple plsql package with the 'beforedata' function trigger. Spec create or replace PACKAGE BIREPORTS AS whereCols varchar2(2000); FUNCTION beforeReportTrig return boolean; end BIREPORTS; Body create or replace PACKAGE BODY BIREPORTS AS   FUNCTION beforeReportTrig return boolean AS   BEGIN       whereCols := ' and d.department_id = 100';     RETURN true;   END beforeReportTrig; END BIREPORTS; you'll notice the additional where clause (whereCols - declared as a public variable) is hard coded. I'll cover parameterizing that in my next post. If you can not wait, check the 10g docs for an example. I have my package compiling successfully in the db. Now, onto the BIP data model definition. 1. Create a new data model and go ahead and create your query(s) as you would normally. 2. In the query dialog box, add in the variables you want replaced at runtime using an ampersand rather than a colon e.g. &whereCols.   select     d.DEPARTMENT_NAME, ...  from    "OE"."EMPLOYEES" e,     "OE"."DEPARTMENTS" d  where   d."DEPARTMENT_ID"= e."DEPARTMENT_ID" &whereCols   Note that 'whereCols' matches the global variable name in our package. When you click OK to clear the dialog, you'll be asked for a default value for the variable, just use ' and 1=1' That leading space is important to keep the SQL valid ie required whitespace. This value will be used for the where clause if case its not set by the function code. 3. Now click on the Event Triggers tree node and create a new trigger of the type Before Data. Type in the default package name, in my example, 'BIREPORTS'. Then hit the update button to get BIP to fetch the valid functions.In my case I get to see the following: Select the BEFOREREPORTTRIG function (or your name) and shuttle it across. 4. Save your data model and now test it. For now, you can update the where clause via the plsql package. Next time ... parametrizing the dynamic clause.

• Please verify my layout: bottom button keeps coming up over keyboard

  - by steff

  Hi everyone, I have a layout which does almost what I want. There's just one bug regarding the button at the bottom. I should stay at the bottom at all times. But whenever I bring up the soft-keyboard the button will be displayed above the keyboard. This is not what I want but it should become covered by the keyboard. Moreover, I'd be happy if you could comment on how the layout's built. Thanks, steff <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <LinearLayout android:id="@+id/l_layout_tags" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:text="TAGS:" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <AutoCompleteTextView android:id="@+id/actv_tags" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:imeOptions="actionDone" /> <ImageButton android:id="@+id/btn_add_tag" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@android:drawable/ic_input_add" android:onClick="addTag"/> </LinearLayout> <ScrollView android:id="@+id/sv_scroll_contents" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/l_layout_tags" android:scrollbarFadeDuration="2000" > <TableLayout android:id="@+id/t_layout_contents" android:layout_width="fill_parent" android:layout_height="wrap_content" android:stretchColumns="1" android:paddingRight="5dip"> <TableRow android:id="@+id/tr_template"> <ImageView android:id="@+id/iv_blank" android:src="@android:color/transparent" /> <EditText android:id="@+id/et_content1" android:gravity="top" android:maxWidth="200dp" android:imeOptions="actionDone" /> </TableRow> </TableLayout> </ScrollView> <LinearLayout android:id="@+id/l_layout_media_btns" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:layout_centerHorizontal="true" android:layout_below="@id/sv_scroll_contents" > <ImageButton android:id="@+id/btn_camera" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@android:drawable/ic_menu_camera" android:onClick="takePicture" /> <ImageButton android:id="@+id/btn_video" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@android:drawable/ic_menu_camera" /> <ImageButton android:id="@+id/btn_audio" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@android:drawable/ic_btn_speak_now" /> <ImageButton android:id="@+id/btn_sketch" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@android:drawable/ic_menu_edit" /> </LinearLayout> <ImageButton android:id="@+id/btn_save_note" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:src="@android:drawable/ic_menu_upload" /> </RelativeLayout>

• Android GPS timeout

  - by Scott Saunders

  I'm writing an Android application that, among other things, needs to send the current GPS coordinates to a server when the user tells it to. From a context menu, I run the service below. The service is a LocationListener and requests updates from the LocationManager. When it gets a location (onLocationChanged()), it removes itself as a listener and sends the coordinates off to the server. All of this is working. However, if GPS coordinates are not quickly available, my service just keeps running until it gets some. It holds up the UI with a progress dialog, which is annoying. Worse, if the user has moved since starting the service, the first GPS coordinates might be wrong and the app will send bad data to the server. I need a timeout on the service. Is there a good way to do that? I'm not very experienced with threads. I think I can run a Runnable in the onStartCommand() method that will somehow count down 30 seconds and then, if there is no GPS result yet, call my service's stop() method. Does that sound like the best way to do this? Alternatively, is it possible to tell if the GPS cannot get a fix? How would I go about doing that? Edit: To further clarify, I'm looking for the best way to "give up" on getting a Location after some amount of time. public class AddCurrentLocation extends Service implements LocationListener { Application app; LocationManager mLocManager; ProgressDialog mDialog; @Override public int onStartCommand(Intent intent, int arg0, int arg1) { app = getApplication(); // show progress dialog if (app.getScreen() != null) { mDialog = ProgressDialog.show(app.getScreen(), "", "Adding Location. Please wait...", true); } // find GPS service and start listening Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_FINE); mLocManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); String bestProvider = mLocManager.getBestProvider(criteria, true); mLocManager.requestLocationUpdates(bestProvider, 2000, 0, this); return START_NOT_STICKY; } private void stop() { mLocManager.removeUpdates(this); if (mDialog != null) { mDialog.dismiss(); } stopSelf(); } @Override public void onLocationChanged(Location location) { // done with GPS stop listening mLocManager.removeUpdates(this); sendLocation(location); // method to send info to server stop(); } // other required methods and sendLocation() ... }

• jQuery doesn't work in IE8?

  - by Wade D Ouellet

  Hi, I am working on a site here: mfm.treethink.net All the jquery works fine in Firefox, Chrome and Safari but on IE8 it gives me errors and the banner at the top doesn't work (which uses the crossSlide jQuery plugin) and as well the image rollovers don't work with the colour change. IE8 is telling me that the errors are on lines 53, 134 and 149 in the source, all of those lines are where the jquery function is declared. $(document).ready(function(){ I am running jquery 1.4. Oddly enough, the other piece of jQuery I have on that page works, the artist browse/select menu on the right. But the banner and image rollovers don't. Here are all the scripts I'm running: 1: the banner - doesn't work in IE8 <script type="text/javascript"> $(function() { $('#banner').crossSlide({ sleep: 5, fade: 1 }, [ <?php $pages = get_posts('numberposts=2000&post_type=artist&post_status=publish'); $i = 1; foreach( $pages as $page ) { $content = $page->post_title; if( empty($content) ) continue; $content = apply_filters('the_content', $content); ?> { src: '/wp-content/uploads/<?php echo $page->post_name ?>.jpg' }, <?php $i++; } ?> ]); }); </script> 2 - image rollovers - doesn't work in IE8 <script type="text/javascript"> $(function(){ $("ul#artists li").hover(function() { /* On hover */ var thumbOver = $(this).find("img").attr("src"); /* Find image source */ /* Swap background */ $(this).find("a.thumb").css({'background' : 'url(' + thumbOver + ') center bottom no-repeat'}); $(this).find("span").stop().fadeTo('fast', 0 , function() { $(this).hide() }); } , function() { $(this).find("span").stop().fadeTo('fast', 1).show(); }); }); </script> 3 - the artist select - works in IE 8 <script> $("#browse-select").change(function() { window.location.href = $(this).val(); }); </script> These scripts were done by referencing previously made scripts, like I said I'm still new to jQuery. The second works in IE8 and the first one is the one that doesn't. I noticed the third one, the only one working, is written differently than the first two non-working ones without a function declaration at the top. Could this have anything to do with it? Any help figuring out this problem would be so appreciated. Thanks a lot, Wade

• Jboss Seam: Enabling Debug page on WebLogic 10.3.2 (11g)

  - by Markos Fragkakis

  Hi all, SKIP TO UPDATE 3 I want to enable the Seam debug page on Weblogic 10.3.2 (11g). So, I have done the following: I have the jboss-seam and jboss-seam-debug jars as dependency in both my ejb and web maven projects (both are modules of my superproject) I put this context parameter in my web.xml: <context-param> <param-name>org.jboss.seam.core.init.debug</param-name> <param-value>true</param-value> </context-param> Now, when I hit the URL of my application, I get the debug page with this exception (full stacktrace at the end of the post): Caused by java.lang.IllegalStateException with message: "No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)" From posts I read it seems that this is somehow related to two jars of jboss-seam or jboss-seam-debug being in the classpath. I opened my ear file and only one of each is present (in the ear) whereas the war itself has no libraries in the WEB-INF/lib. I have also read of another way to initialize debug page using the components.xml. I also tried to include the following components.xml in the WEB-INF, but it didn't work either: <?xml version="1.0" encoding="UTF-8"?> <components xmlns="http://jboss.com/products/seam/components" xmlns:core="http://jboss.com/products/seam/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://jboss.com/products/seam/core http://jboss.com/products/seam/core-2.2.xsd http://jboss.com/products/seam/components http://jboss.com/products/seam/components-2.2.xsd"> <core:init debug="true"/> </components> Any suggestions on what to do to enable the debug page correctly?

They have an outer EAR project containing the inner WAR project. They discuss that this may be related to how jars end up in the projects. I use Maven, and I had set it to create "Skinny Wars", that is excluding all jar dependencies from the inner WAR project, so that it remains small in size. All its dependencies are contained in the EAR and are used by all other modules. I changed the settings of the maven-war-plugin to leave inside the war the web-specific jars (the ones mentioned in the link, like RichFaces, jboss-seam-debug, Facelets etc). However, the problem has reverted to its previous form. I now get the debug page, whatever link I press, with the initial exception. Caused by java.lang.IllegalStateException with message: "No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)" UPDATE 3: The structure of the application .ear is the following: application.ear |--> APP-INF | |--> classes |--> lib (all jar dependencies go here, including the WAR dependencies, EJB module dependencies) |-->META_INF | |--> application.xml | |--> data-sources.xml | |--> MANIFEST.MF | |--> weblogic.xml | |--> weblogic-application.xml |--> jboss-seam-2.2.0.GA.jar |--> myEjbModule1.jar |--> myEjbModule2.jar |--> myEjbModule3.jar |--> myEjbModule4.jar |--> myWar.war (NO libraries in WEB-INF/lib, finds everything in EAR/lib) When deploying .ear application WITHOUT debug enabled (not including the jboss-seam-debug.jar in the ear), the application is loaded correctly. When deploying WITH jboss-seam-debug.jar in the EAR (EAR/lib directory), the application does not appear, but ONLY the debug page with the following exception (stacktrace at the end): Exception during request processing: Caused by java.lang.IllegalStateException with message: "No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)" When "JBoss-izing" the same EAR (remove hibernate jars, which are provided by JBoss, and move all libraries from EAR/lib to EAR root), the application loads correctly.

• How can I make a WPF TreeView data binding lazy and asynchronous?

  - by pauldoo

  I am learning how to use data binding in WPF for a TreeView. I am procedurally creating the Binding object, setting Source, Path, and Converter properties to point to my own classes. I can even go as far as setting IsAsync and I can see the GUI update asynchronously when I explore the tree. So far so good! My problem is that WPF eagerly evaluates parts of the tree prior to them being expanded in the GUI. If left long enough this would result in the entire tree being evaluated (well actually in this example my tree is infinite, but you get the idea). I would like the tree only be evaluated on demand as the user expands the nodes. Is this possible using the existing asynchronous data binding stuff in the WPF? As an aside I have not figured out how ObjectDataProvider relates to this task. My XAML code contains only a single TreeView object, and my C# code is: public partial class Window1 : Window { public Window1() { InitializeComponent(); treeView.Items.Add( CreateItem(2) ); } static TreeViewItem CreateItem(int number) { TreeViewItem item = new TreeViewItem(); item.Header = number; Binding b = new Binding(); b.Converter = new MyConverter(); b.Source = new MyDataProvider(number); b.Path = new PropertyPath("Value"); b.IsAsync = true; item.SetBinding(TreeView.ItemsSourceProperty, b); return item; } class MyDataProvider { readonly int m_value; public MyDataProvider(int value) { m_value = value; } public int[] Value { get { // Sleep to mimick a costly operation that should not hang the UI System.Threading.Thread.Sleep(2000); System.Diagnostics.Debug.Write(string.Format("Evaluated for {0}\n", m_value)); return new int[] { m_value * 2, m_value + 1, }; } } } class MyConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { // Convert the double to an int. int[] values = (int[])value; IList<TreeViewItem> result = new List<TreeViewItem>(); foreach (int i in values) { result.Add(CreateItem(i)); } return result; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new InvalidOperationException("Not implemented."); } } } Note: I have previously managed to do lazy evaluation of the tree nodes by adding WPF event handlers and directly adding items when the event handlers are triggered. I'm trying to move away from that and use data binding instead (which I understand is more in spirit with "the WPF way").

• 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>

• Playing an InputStream video in Blackberry JDE.

  - by Jenny

  I think I'm using InputStream incorrectly with a Blackberry 9000 simulator: I found some sample code, http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How%5FTo%5F-%5FPlay%5Fvideo%5Fwithin%5Fa%5FBlackBerry%5Fsmartphone%5Fapplication.html?nodeid=1383173&vernum=0 that lets you play video from within a Blackberry App. The code claims it can handle HTTP, but it's taken some fandangling to get it to actually approach doing so: http://pastie.org/609491 Specifically, I'm doing: StreamConnection s = null; s = (StreamConnection)Connector.open("http://10.252.9.15/eggs.3gp"); HttpConnection c = (HttpConnection)s; InputStream i = c.openInputStream(); System.out.println("~~~~~I have a connection?~~~~~~" + c); System.out.println("~~~~~I have a URL?~~~~" + c.getURL()); System.out.println("~~~~~I have a type?~~~~" + c.getType()); System.out.println("~~~~~I have a status?~~~~~~" + c.getResponseCode()); System.out.println("~~~~~I have a stream?~~~~~~" + i); player = Manager.createPlayer(i, c.getType()); I've found that this is the only way I can get an InputStream from an HTTPConnection without causing a: "JUM Error 104: Uncaught NullPointer Exception". (That is, the casting as a StreamConnection, and THEN as an HttpConnection stops it from crashing). However, I'm still not streaming video. Before, a stream wasn't able to be created (it would crash with the null pointer exception). Now, a stream is being made, the debugger claims it's begining to stream video from it...and nothing happens. No video plays. The app doesn't freeze, or crash or anything. I can 'pause' and 'play' freely, and get appropriate debug messages for both. But no video shows up. If I'm playing a video stored locally on the blackberry, everything is fine (it actually plays the video), so I know the Player itself is working fine, I"m just wondering if maybe I have something wrong with my stream? The API says the player can take in an InputStream. Is there a specific kind it needs? How can I query my inputstream to know if it's valid? It existing is further than I've gotten before. -Jenny Edit: I'm on a Blackberry Bold simulator (9000). I've heard that some versions of phones do NOT stream video via HTTP, however, the Bold does. I have yet to see examples of this though. When I go to the internet and point at a blackberry playable video, it attempts to stream, and then asks me to physically download the file (and then plays fine once I download). Edit: Also, I have a physical blackberry Bold, as well, but it can't stream either (I've gone to m.youtube.com, only to get a server/content not found error). Is there something special I need to do to stream RTSP content?

• Using FFMPEG to reliably convert videos to mp4 for iphone/ipod and flash players

  - by Jake Stevenson

  I need to convert videos for use in both a flash player and the iphone/ipod touch. I'm using the following batch script with ffmpeg: @echo off ffmpeg.exe -i %1 -s qvga -acodec libfaac -ar 22050 -ab 128k -vcodec libx264 -threads 0 -f ipod %2 This always outputs an mp4 file, and I can always play it on my PC. The videos also seem to play fine on my iphone 3GS. But with some input files it won't work for older iphone versions (3G and iPod touch).

• GWTAI applet integration in GWT problem

  - by andy

  Hi everybody. I'm working with gwtai to integrate a java applet into my gwt - project. Basic communication from my main application to the applet (such as invoking simple methods that return int or boolean values) works. But the main reason why I need to integrate this applet is, that I need it to connect to another server and receive a answer and pass it to my gwt-application. So there's one basic method in the applet: public String SendAndReceive(String host, int sendPort, int receivePort, String query) that connects to the server, receives an answer and returns this answer as a string. When I now try to invoke this method like this: applet.SendAndReceive("0.0.0.0", 9099, 2000, "show streams;"); I constantly run into following error (full error message at the end): com.google.gwt.core.client.JavaScriptException: (String): Error calling method on NPObject! [plugin exception: java.security.AccessControlException: access denied (java.util.PropertyPermission * read,write)] I couldn't find a solution (for gwtai is a quite uncommon topic), what I found out (and what the Exception let's one assume) is, that there's a security problem - maybe because I'm connecting to another server. I also read something about browser's Single Origin Policy, what would point in the same direction...up to now I have never worked with java applets. So if someone has a solution or a hint I would be very thankful. If more code is helpful I can give. Thanks, Andy the full error message: 21:03:49.864 [ERROR] [follovizergwt] Unable to load module entry point class follovizer.gwt.client.FolloVizerGWT (see associated exception for details) com.google.gwt.core.client.JavaScriptException: (String): Error calling method on NPObject!

• mysql never releases memory

  - by Ishu

  I have a production server clocking about 4 million page views per month. The server has got 8GB of RAM and mysql acts as a database. I am facing problems in handling mysql to take this load. I need to restart mysql twice a day to handle this thing. The problem with mysql is that it starts with some particular occupation, the memory consumed by mysql keeps on increasing untill it reaches the maximum it can consume and then mysql stops responding slowly or does not respond at all, which freezes the server. All my tables are indexed properly and there are no long queries. I need some one to help on how to go about debugging what to do here. All my tables are myisam. I have tried configuring the parameters key_buffer etc but to no rescue. Any sort of help is greatly appreciated. Here are some parameters which may help. mysql --version mysql Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (i686) using readline 5.1 mysql> show variables;

• jQuery Cycle plugin IE6/7 issues

  - by Aaron Moodie

  I've implemented a slideshow using the Cycle plugin, which is working in all browsers except IE6&7, where the images just show up in a list, and the #page_copy div is not hiding. I've been going through the code all day without any luck, and not exactly sure how or what I should be looking for. What would be the best way to go about debugging this issue? I know that the #page_copy div is hiding when I remove the rest of the code, and I've tried the reverse (which had no result) <script type="text/javascript" charset="utf-8"> jQuery.fn.fadeToggle = function(speed, easing, callback) { return this.animate({opacity: 'toggle'}, speed, easing, callback); }; $(document).ready(function() { $('#page_copy').hide(); $('a#info_close_button').click(function() { $('#page_copy').fadeOut(200); return false; }); $('a#info_button').click(function() { $('#page_copy').fadeToggle(200); return false; }); }); $(window).load(function() { // vertically center single image var $image_cnt = $("#images > img").size(); if($image_cnt < 2) { var $single_img = $("#images").children(':first-child'); var h = $single_img.height(); $single_img.css({ marginTop: (620 - h) / 2, }); $(".next").css("display","none"); $(".prev").css("display","none"); } }); // wait until images have loaded before starting cycle $(window).load(function() { // front image rotator $('#images').cycle({ fx: 'fade', speed: 300, next: '.next', prev: '.prev', containerResize: 0, timeout: 0, delay: -2000, before: onBefore }); }); // hide all but the first image when page loads $(document).ready(function() { $('#images img:gt(0)').hide(); }); // callback fired when each slide transition begins function onBefore(curr,next,opts) { var $slide = $(next); var w = $slide.width(); var h = $slide.height(); $slide.css({ marginTop: (620 - h) / 2, marginLeft: (650 - w) / 2 }); }; </script>

• ffmpeg - How to determine if -movflags faststart is enabled? PHP

  - by IIIOXIII

  While I am able to encode an mp4 file which I can plan on my local windows machine, I am having trouble encoding files to mp4 which are readable when streaming by safari, etc. After a bit of reading, I believe my issue is that I must move the metadata from the end of the file to the beginning in order for the converted mp4 files to be streamable. To that end, I am trying to find out if the build of ffmpeg that I am currently using is able to use the -movflags faststart option through php - as my current outputted mp4 files are not working when streamed online. This is the way I am now echoing the -help, -formats, -codecs, but I am not seeing anything about -movflags faststart in any of the lists: exec($ffmpegPath." -help", $codecArr); for($ii=0;$ii<count($codecArr);$ii++){ echo $codecArr[$ii].'</br>'; } Is there a similar method of determining if -movflags fastart is available to my ffmpeg build? Any other way? Should it be listed with any of the previously suggested commands? -help/-formats? Can someone that knows it is enabled in their version of ffmpeg check to see if it is listed under -help or -formats, etc.? TIA.

• Using Android SAXParser, one my my XML Elements is mysteriously breaking in half.

  - by Drennen

  And its not '&' Im using the SAXParser object do parse the actual XML. This is normally done by passing a URL to the XMLReader.Parse method. Because my XML is coming from a POST request to a webservice, I am saving that result as a String and then employing StringReader / InputSource to feed this string back to the XMLReader.Parse method. However, something strange is happening at the 2001st character of the XMLstring. The 'characters' method of the document handler is being called TWICE in between the startElement and endElement methods, effectively breaking my string (in this case a project title) into two pieces. Because I am instantiating objects in my characters method, I am getting two objects instead of one. This line, about 2000 chars into the string fires 'characters' two times, breaking between "Lower" and "Level" <title>SUMC-BOOKSTORE, LOWER LEVEL RENOVATIONS</title> When I bypass the StringReader / InputSource workaround and feed a flat XML file to XMLReader.Parse, it works absolutely fine. Something about StringReader and or InputSource is somehow screwing this up. Here is my method that takes and XML string and parses is through the SAXParser. public void parseXML(String XMLstring) { try { SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); XMLReader xr = sp.getXMLReader(); xr.setContentHandler(this); // Something is happening in the StringReader or InputSource // That cuts the XML element in half at the 2001 character mark. StringReader sr = new StringReader(XMLstring); InputSource is = new InputSource(sr); xr.parse(is); } catch (IOException e) { Log.e("CMS1", e.toString()); } catch (SAXException e) { Log.e("CMS2", e.toString()); } catch (ParserConfigurationException e) { Log.e("CMS3", e.toString()); } } I would greatly appreciate any ideas on how to not have 'characters' firing off twice when I get to this point in the XML String. Or, show me how to use a POST request and still pass off the URL to the Parse function. THANK YOU.

• Which version of MSXML should I use?

  - by Cheeso

  Seems like this would be a common question, though I could not find it on SO. Which version of MSXML should I use in my applications, and more importantly, how should I decide? There is MSXML3, 4, 5 and 6. I recently posted some code in calling-wcf-service-by-vbscript that used MSXML v4. AnthonyWJones posted that I shouldn't use 4, but instead 3 or 6, but probably 3. Certainly not v5! Why? I'd like to know more about the criteria for selecting the version of MSXML to use in my apps. Bonus question: Does anyone have a summary of the differences between the various versions of MSXML over time? Summary so far: MSXML6 Should be first choice. was released in 2006, and includes perf and compliance fixes. Use this if you can. It's good. There are no merge modules; to bundle the MSXML6 runtime with your app, MS suggests packaging the MSXML6 msi file. MSXML6 is an upgrade from MSXML3/4 but does not replace them, because it discontinues some features. You can get the MSI here. MSXML3 Second choice. Most widely deployed version. Originally shipped in March 2000. Actively maintained, no new features. Currently supported, if you are on SP5 (shipped in 2005) or later. SP7 is current (also from 2005). MSXML5 was released only as part of MS-Office. Currently supported by Microsoft, but only as part of Office, not for building apps. Don't build apps that depend on MSXML5: Verboten. MSXML4 originally shipped? Currently in "maintenance mode". Microsoft is encouraging people to move off MSXML4 to MSXML6. Currently supported if you are on MSXML4SP2 or later, which shipped in 2003. download MSXML4SP2 here. Can be redisributed. Using the right version of MSXML in Internet Explorer is a good entry on the blog from Microsoft's xmlteam.

• Streaming Video with Blackberry Simulator

  - by Jenny

  So, I wrote a quick little app for the iphone that takes in an http URL, and plays the .mp4 video located at that URL (it does more than that, of course, but that's the meat of it). Naturally, I wanted to have it on more than just a single mobile platform, so I decided to target Blackberry next. However, I'm running into a lot of problems with the Blackberry Environment. First of all, I learn that I can only download 256k files! I learn how to set that variable in my MDS simulator (and learn that this is NOT a production solution, because any end users will have to have their BES or MDS admin change the setting there). Then, I find a video less than 2 MB I can practice with. Going to the browser prompts me to save the video (rather than it playing in the browser like I expected). After saving the video, it refuses to play, saying it's the wrong format. So. I can't find a reference to IF Blackberry can stream with HTTP (i"ve heard it CAN use RTSP, though, and heard some rumors that it can't use HTTP, which would really suck). I also can't find a reference to what format blackberry uses (although I can find a million programs that will convert one file to the 'blackberry' format). Surely SOMEONE must have tried to stream video with the blackberry before. How did they go about doing so? Is it just a hopeless pipedream? Will I have to go with RTSP? Sorry for the lack of a concrete question...I'm just really lost, and I hate how so many tutorials or forum posts seem to assume I know the capabilities of the Blackberry... Edit: I finally found out that the .3gp (which I'd never heard of ) format is what Blackberry uses. Still have no idea how to stream videos off the web, though. I found a tutorial: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How%5FTo%5F-%5FPlay%5Fvideo%5Fwithin%5Fa%5FBlackBerry%5Fsmartphone%5Fapplication.html?nodeid=1383173&vernum=0 That seemed to be useful, but the code doesn't work if you give it a URL (even though it claims it does).

• dojo/dijit ContentPane setting content

  - by Kitson

  I am trying append some XML retrieved via a dojo.XHRGet to a dijit.layout.ContentPane. Everything works ok in Firefox (3.6) but in Chrome, I only get back 'undefined' in the particular ContentPane. My code looks something like this: var cp = dijit.byId("mapDetailsPane"); cp.destroyDescendants(); // there are some existing Widgets/content I want to clear // and replace with the new content var xhrData = { url : "getsomexml.php", handleAs: "xml", preventCache: true, failOk: true }; var deferred = new dojo.xhrGet(xhrData); deferred.addCallback(function(data) { console.log(data.firstChild); // get a DOM object in both Firebug // and Chrome Dev Tools cp.attr("content",data.firstChild); // get the XML appended to the doc in Firefox, // but "undefined" in Chrome }); Because in both browsers I get back a valid Document object I know XHRGet is working fine, but there seems to be some sort of difference in how the content is being set. Is there a better way to handle the return data from the request? There was a request to see my XML, so here is part of it... <?xml version="1.0" encoding="UTF-8" standalone="no"?> <svg xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" width="672" height="1674"> <defs> <style type="text/css"> <![CDATA[ ...bunch of CSS... ]]> </style> <marker refX="0" refY="0" orient="auto" id="A00End" style="overflow: visible;"> ...bunch more defs... </defs> <g id="endpoints"> ...bunch of SVG with a some... <a xlink:href="javascript:gotoLogLine(16423,55);" xlink:type="simple">...more svg...</a> </g> </svg> I have run the output XML trough the WC3 validator for XML to verify it is valid. Like I said before, works in FireFox 3.6. I tried it on Safari and I got the same "undefined" so it seems to be related to Webkit.

• Slow performance when utilizing Interop.DSOFile to search files by Custom Document Property

  - by Gradatc

  I am new to the world of VB.NET and have been tasked to put together a little program to search a directory of about 2000 Excel spreadsheets and put together a list to display based on the value of a Custom Document Property within that spreadsheet file. Given that I am far from a computer programmer by education or trade, this has been an adventure. I've gotten it to work, the results are fine. The problem is, it takes well over a minute to run. It is being run over a LAN connection. When I run it locally (using a 'test' directory of about 300 files) it executes in about 4 seconds. I'm not sure even what to expect as a reasonable execution speed, so I thought I would ask here. The code is below, if anyone thinks changes there might be of use in speeding things up. Thank you in advance! Private Sub listByPt() Dim di As New IO.DirectoryInfo(dir_loc) Dim aryFiles As IO.FileInfo() = di.GetFiles("*" & ext_to_check) Dim fi As IO.FileInfo Dim dso As DSOFile.OleDocumentProperties Dim sfilename As String Dim sheetInfo As Object Dim sfileCount As String Dim ifilesDone As Integer Dim errorList As New ArrayList() Dim ErrorFile As Object Dim ErrorMessage As String 'Initialize progress bar values ifilesDone = 0 sfileCount = di.GetFiles("*" & ext_to_check).Length Me.lblHighProgress.Text = sfileCount Me.lblLowProgress.Text = 0 With Me.progressMain .Maximum = di.GetFiles("*" & ext_to_check).Length .Minimum = 0 .Value = 0 End With 'Loop through all files in the search directory For Each fi In aryFiles dso = New DSOFile.OleDocumentProperties sfilename = fi.FullName Try dso.Open(sfilename, True) 'grab the PT Initials off of the logsheet Catch excep As Runtime.InteropServices.COMException errorList.Add(sfilename) End Try Try sheetInfo = dso.CustomProperties("PTNameChecker").Value Catch ex As Runtime.InteropServices.COMException sheetInfo = "NONE" End Try 'Check to see if the initials on the log sheet 'match those we are searching for If sheetInfo = lstInitials.SelectedValue Then Dim logsheet As New LogSheet logsheet.PTInitials = sheetInfo logsheet.FileName = sfilename PTFiles.Add(logsheet) End If 'update progress bar Me.progressMain.Increment(1) ifilesDone = ifilesDone + 1 lblLowProgress.Text = ifilesDone dso.Close() Next lstResults.Items.Clear() 'loop through results in the PTFiles list 'add results to the listbox, removing the path info For Each showsheet As LogSheet In PTFiles lstResults.Items.Add(Path.GetFileNameWithoutExtension(showsheet.FileName)) Next 'build error message to display to user ErrorMessage = "" For Each ErrorFile In errorList ErrorMessage += ErrorFile & vbCrLf Next MsgBox("The following Log Sheets were unable to be checked" _ & vbCrLf & ErrorMessage) PTFiles.Clear() 'empty PTFiles for next use End Sub
