Any help would be appreciated.

Run Grunt task in Visual Studio Release Build with a bat file

Make it use the minified code when the Web.config compilation debug is set to false  <Target Name="CustomCollectFiles"> <ItemGroup> <_CustomFiles Include="Scripts-Release\**\*" /> </ItemGroup> </Target> That should be all you need to get a Grunt task to minify and combine JS (plus other tasks) in Visual Studio Release build with debug = false. This is a great video of Steve Sanderson talking about SPAs, npm, Knockout, Grunt, Gulp, ect. I highly recommend it.

Multilingual sites and Google search results, do subfolders really work?

- by AWinter

About three months ago we added an English version of our, previously Japanese only, site http://www.clubberia.com under the subfolder http://www.clubberia.com/en/ we've tried to follow the sometimes incomplete best practices laid out by Google by adding alternate tags to all pages that are currently translated. The top page for instance has the following meta tags for language. <link rel="canonical" href="/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> While the English main page under /en/ has <link rel="canonical" href="/en/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> We also have these alternate languages setup in the sitemap. (as per Google's recommendations) http://www.clubberia.com/sitemap.xml It seems however that Google absolutely refuses to show the English top page in results when the user is using English at google.com if you search for "clubberia" you'll, as of this post, get the Japanese description and a title that Google has apparently invented instead of the title and description in the meta-tags for the /en/ index page. Does anyone have any experience with subfolders actually working to affect search results? Am I being too impatient, or possibly doing something incorrect? Should we just give up on subfolders and push to subdomains (not the prettiest option)?

Entity Object Extension in Oracle Application R12

- by Manoj Madhusoodanan

In this blog I will explain how to perform Entity Object ( EO ) Extension.As a prerequisite please read my previous blog.I am doing this exercise based on PL/SQL EO. Following attributes are part of FndUserEO. Here I will add a validation to UserName attribute "Length should be > 5". Following steps need to perform. 1) Download all files of "Entity Object Based on PL/SQL" to JDEV_USER_HOME/myprojects and JDEV_USER_HOME/myclasses.If you want to see the content of source java file decompile it and save it in JDEV_USER_HOME/myprojects. 2) Create new Entity Object XXFndUserEO as follows. Include all attributes of parent EO. 3) Add the validation code snippet to XXFndUserEOImpl.java as follows. 4) Create the substitution as follows. 5) Migrate files to $JAVA_TOP. xxcustom.oracle.apps.fnd.user.schema.server.XXFndUserEOImpl.javaxxcustom.oracle.apps.fnd.user.schema.server.XXFndUserEO.xml 6) Migrate the substitution.. 7) Bounce the server. 8) Verify the substitution has applied properly. Access Create User Page and create a User. You can see the validation message if user name length is less than 5. Give User Name as XXCUST4 and verify the table. The FND_USER has created successfully.

404s on password protected content

- by tjb1982

I'm new to WordPress and SEO, generally, but we've been running into problems with our site that don't seem to make sense to me. The problem is that our editor likes to schedule posts and/or mark them private until she is ready to make them public, but somehow Google is crawling these posts and getting 404s (because they are password protected). How does Google know they exist in the first place? I checked the sitemap.xml file and don't see a record of the post. One of the offending posts was marked public, but is scheduled for a future date. Could that have something to do with it? I've tried to Google the answer, and I came up with a good amount of reassurance that this won't hurt the site, but I'm still wondering how it's happening in the first place. It's hard because I don't know exactly what the editor's workflow is. Is it possible she's posting publicly first and then revising it to be private only after it's too late? Does anyone know how Google finds WordPress URLs it shouldn't have access to?

Tomcat's connection pool opens only 20 connections to mysql

- by stck

I have a java application with following line in context.xml <Resource driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" initialSize="10" maxWait="7000" name="jdbc/app" password="pass" type="javax.sql.DataSource" url="jdbc:mysql://dbhost:3306/dbname?autoReconnect=true" username="user" validationQuery="SELECT 1" removeAbandoned="true" removeAbandonedTimeout="30" logAbandoned="true" /> In mysql 'show variables' tells me that max_connections is 151. Still, use information_schema; select count(*) from processlist where User = 'user'; never shows me more than 20 connections. On tomcat's catalina.out -log I get Caused by: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot get a connection, pool exhausted at org.apache.tomcat.dbcp.dbcp.PoolingDataSource.getConnection(PoolingDataSource.java:103) at org.apache.tomcat.dbcp.dbcp.BasicDataSource.getConnection(BasicDataSource.java:540) at org.springframework.jdbc.datasource.DataSourceUtils.doGetConnection(DataSourceUtils.java:113) at org.springframework.jdbc.datasource.DataSourceUtils.getConnection(DataSourceUtils.java:79) What should I check for to find the problem?

Methods for getting static data from obj-c to Parse (database)

- by Phil

I'm starting out thinking out how best to code my latest game on iOS, and I want to use parse.com to store pretty much everything, so I can easily change things. What I'm not sure about is how to get static data into parse, or at least the best method. I've read about using NSMutableDictionary, pLists, JSON, XML files etc. Let's say for example in AS3 I could create a simple data object like so... static var playerData:Object = {position:{startX:200, startY:200}}; Stick it in a static class, and bingo I've got my static data to use how I see fit. Basically I'm looking for the best method to do the same thing in Obj-c, but the data is not to be stored directly in the iOS game, but to be sent to parse.com to be stored on their database there. The game (at least the distribution version) will only load data from the parse database, so however I'm getting the static data into parse I want to be able to remove it from being included in the eventual iOS file. So any ideas on the best methods to sort that? If I had longer on this project, it might be nice to use storyboards and create a simple game editor to send data to parse....actually maybe that's a good idea, it's just I'm new to obj-c and I'm looking for the most straightforward (see quickest) way to achieve things. Thanks for any advice.

Proper XAML for Windows 8 Applications [closed]

- by Jaapjan

Traditionally, my programs do their work in the background and when I do have to make an interface for some reason, they often do not need to be complex which means I can use a simple Windows Forms or console application. But lets be honest-- Windows Forms? That is so ... ancient! Instead I have been looking at Windows 8. A new interface, different, maybe better-- but fun to give a try. Which means XAML. Now, XAML isn't all that hard in concept. Panel here, button there-- A smattering of XML. My question in short: Where can I find resources that teach me how to write good XAML code for Windows 8 applications? The long version: How do I combine XAML constructs to achieve effects? Horizontal panels with multiple sections you can scroll through with your finger, the proper way? How should you use default style resources Windows 8 might give you by default? How do I properly create a panel with user info on the right? Left aligned stackpanels with embedded dockpanels? Yes? No? Why?

ubuntu 12.04 LTS hangs on boot when external monitor is connected

- by vladeta

I have a problem with my fresh installed Ubuntu 12.04 LTS on my Dell M4600: nVidia quadro 2000M i7-2860 16GB ram 128GB SSD Dell/Samsung 750GB HDD IPS RGB laptop display When it is connected via DP++ to the external Dell U2311H monitor, it hangs on boot or when wakening from suspend. If I detach the DP cable it boots normally. I have tried all combinations that I have found, as adding to grub: "no splash", "boot=pci", "acpi=off", etc... I have also changed in nVidia X settings that external monitor is the primary one and also tried to delete monitor.xml file. There is no change it hangs each time after grub. It starts to load daemons then both screens are blank and then completely hangs with beep sound. What I discovered is if I detach the cable and wait for about 2 sec after grub starts booting and then physically connect DP cable while the Ubuntu is still booting everything works normally and I have a picture on my external screen while the laptop screen is off, just as I wanted. Do you maybe know how to solve this issue? Thank You.

Odd SVN Checkout failures occur frequenctly on VMWare virtual machines

- by snowballhg

We've recently been experiencing seemingly random SVN checkout failures on our Hudson build system. Google search has failed me; I'm hoping the super user community can help me out :-) We are occasionally receiving the following SVN error when our Hudson build jobs checkout source via the Hudson Subversion plug-in (which uses svn kit): ERROR: Failed to check out http://server/svnroot/trunk org.tmatesoft.svn.core.SVNException: svn: Processing REPORT request response failed: XML document structures must start and end within the same entity. (/svnroot/!svn/vcc/default) svn: REPORT request failed on '/svnroot/!svn/vcc/default' This issue seems to only occur when checking out from our Virtual Machines (Windows XP, Fedora 9, Fedora 12) using Hudson's SVN Plug-in. Systems that use the traditional SVN client seem to work. SVN Server version: 1.6.6 Hudson version: 1.377 Hudson SVN Plugin Version: 1.17 Has anyone dealt with this issue, or have any suggestions?

Turn a Kindle into a Weather Display Station

- by Jason Fitzpatrick

The e-ink display, network connectivity, and low-power consumption of Kindle ebook readers make them a perfect candidate for an infrequently refreshed high-visibility display–like a weather display. Read on to see how to hack a Kindle to serve up the local weather. Tinker and hardware hacker Matt Petroff hacked his Kindle to accept input from a web server and then, graciously and in the spirit of geeky projects everywhere, shared his source code. He explains the heart of the project: The server side of the system uses shell and Python scripts to convert weather forecast data into an image for the Kindle. The scripts first download and parse forecast data from NOAA via the National Digital Forecast Database XML/SOAP Service. After parsing the data, the data then needs to be converted into an image. This is accomplished by preprocessing a specially crafted SVG file to insert temperatures, forecast symbols, and days of the week. This SVG is then rendered as a PNG using rsvg-convert and converted to a grayscale, no transparency color space as required by the Kindle using pngcrush. Finally, it is copied to a public location on the web server. The Kindle is set to refresh twice a day (you could easily tweak the scripts for a more frequent refresh) and displays the forecast as seen in the photo above–with crisp and easy to read text and icons. Hit up the link below for more information and the project’s source code.

Force Run System File Checker (SFC.exe)

Is there a way I can force SFC to scan again and make the new fixes on reboot? Probably by deleting some file or something?

Integrating Amazon EC2 in Java via NetBeans IDE

- by Geertjan

Next, having looked at Amazon Associates services and Amazon S3, let's take a look at Amazon EC2, the elastic compute cloud which provides remote computing services. I started by launching an instance of Ubuntu Server 14.04 on Amazon EC2, which looks a bit like this in the on-line AWS Management Console, though I whitened out most of the details: Now that I have at least one running instance available on Amazon EC2, it makes sense to use the services that are integrated into NetBeans IDE: I created a new application with one class, named "AmazonEC2Demo". Then I dragged the "describeInstances" service that you see above, with the mouse, into the class. Then the IDE automatically created all the other files you see below, i.e., 4 Java classes and one properties file: In the properties file, register the access ID and secret keys. These are read by the other generated Java classes. Signing and authentication are done automatically by the code that is generated, i.e., there's nothing generic you need to do and you can immediately begin working on your domain-specific code. Finally, you're now able to rewrite the code in "AmazonEC2Demo" to connect to Amazon EC2 and obtain information about your running instance: public class AmazonEC2Demo { public static void main(String[] args) { String instanceId1 = "i-something"; RestResponse result; try { result = AmazonEC2Service.describeInstances(instanceId1); System.out.println(result.getDataAsString()); } catch (IOException ex) { Logger.getLogger(AmazonEC2Demo.class.getName()).log(Level.SEVERE, null, ex); } } } From the above, you'll receive a chunk of XML with data about the running instance, it's name, status, dates, etc. In other words, you're now ready to integrate Amazon EC2 features directly into the applications you're writing, without very much work to get started. Within about 5 minutes, you're working on your business logic, rather than on the generic code that anyone needs when integrating with Amazon EC2.

Stop Time Sync Between Host and Guest - VirtualBox

- by KoopaTroopa

So I've been googling and I've tried the following commands. I want to stop the virtual machine from having the correct time and just to stick with what time it last recorded. The host operating system is Ubuntu 12.04 and the guest is Windows XP. I've turned time syncing off in XP so it won't do that when I connect to the Internet. However it does appear to take the time from ubuntu and set it as it's own. VBoxManage setextradata XP11 “VBoxInternal/TM/WarpDrivePercentage” 200 vboxmanage setextradata XP11 "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" "1" Both commands haven't work as the time is always set to the exact same as Ubuntu's. I've located the extradata entry in the virtualbox XML file. It states both changes that the commands above are set to make. But of course it still hasn't stopped updating the time. <ExtraData> <ExtraDataItem name="GUI/LastGuestSizeHint" value="1152,864"/> <ExtraDataItem name="GUI/LastNormalWindowPosition" value="74,52,1152,911"/> <ExtraDataItem name="VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" value="1"/> <ExtraDataItem name="“VBoxInternal/TM/WarpDrivePercentage”" value="200"/> </ExtraData>

Optimising news fetching

- by aceBox

I have a web scraper for scraping news from different sources in wp7. My current appraoch for doing this is: load newspapers information from xml file. go to the specified sections and fetch the urls of the news items. go to each url and fetch headline, image, publisher. display using a MVVM architecture of windows phone. The whole thing takes place asynchronously...meaning as soon as url from a section of a newspaper is fetched it is added to the queue, and the second stage consisting of fetching headline, image etc starts... and as soon this is fetched even for one article, it is displayed. Later on as more articles are fetched, they are added on to the list. For the fetching purpose I am using a SmartThreadPool(http://www.codeproject.com/Articles/7933/Smart-Thread-Pool) for windows phone. My problem is that...even for fetching around 80 items (in total) from 9 publications, it is taking more than a minute. How can i speed up the procedure? Note: I have a two stage approach because many times the images are not available with headlines, and are only found in the article.

Weblogic Class-Path Dependencies EAR

- by user18287

I am deploying an EAR in a WebLogic node with many jars defined in the bootstrap (startWeblogicServer.bat) class-path. The problem is that my ear and the bootstrap contain different versions of the same jars, not only that but certain jars contain extracted third party libraries which also differ in version from the WebLogic bootstrap jars causing all kinds of classpath errors. I know you can set preferred jars in the EAR application xml but, this can be very tedious to resolve with regards to jars which include extracted third party libraries in terms of understanding all the dependencies.. Is there a correct approach that i need to be taking here? Am i thinking about this in the wrong way? Any help would be greatly appreciated! So far prefer-web-inf-classes has been recommended but wont work because i'm not deploying a WAR, also prefer-application-packages is what we are currently using but still has the issue described above... Anymore advice out there?? Thanks!

Robust way to keep records of software releases?

- by japreiss

We release a number of small plug-ins that go along with our software. Each plug-in allows our software to talk to a single manufactuer's hardware. I would like to devise a system for keeping track of plug-in releases. Example info that should be stored: Hardware manufacturer name 32-bit? 64-bit? both? What modes of operation does the hardware support? What versions of the manufacturer's driver have been tested with the plugin? Desirable properties of the system: Able to synchronize with version control software Stores data in human-readable text file (also good for differ tool) Free visual, spreadsheet-like editor available Able to do simple analysis like "What is the oldest plug-in?" I've got to imagine that someone else has tackled this problem already. Right now my best guess is XML/JSON with a visual editor, but I have been disappointed in the editors I've tried so far. I'd like to get input from some more experienced developers. Thanks!

Internet Explorer cannot download rss.php

It throws an error, Internet Explorer cannot download rss.php from www.example.com. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. But when I click a link to view the same feed, it doesn't throw an error but displays the XML instead. Are there any ways I caan fix this, that don't involve OS hacks? Also, if I try to put an xsl stylesheet on it, it tries to download the file no matter what and still errors.

Laptop power button not working

- by DyP

I have a (seemingly rather exotic) Dell Latitude XT2 notebook running Lubuntu 12.04, fresh install. Tried to get the power button to work as expected (opening lubuntu-logout, just as I think it was meant to be out-of-the box), but no success: power button does nothing but forced power-off on long press. Here some more information, please ask if something more could help: Power button is recognized as a device: xinput lists Power Button as a slave keyboard at /dev/input/event1, and I can run a tool to listen to that device and invoke some action (successfully). But using .config/openbox/lubuntu-rc.xml to assign some action to XF86ShutDown or XF86PowerOff does nothing. Works well for any key of the keyboard. xinput --test reports a keycode (key press, key release) of 124 when pressing & releasing the power button. xmodmap -pk lists 124 mapped to XF86PowerOff which seems correct to me (btw: is this the same as XF86ShutDown?) When assigning another keysymname to the 124 keycode, e.g. 'w', still nothing happens when pressing the power button (no window seems to receive a 'w'). Works well for any key on the keyboard. The outputs of xev for a press/release of the power button irritate me: MappingNotify event, serial 41, synthetic NO, window 0x0, request MappingKeyboard, first_keycode 8, count 248 FocusOut event, serial 41, synthetic NO, window 0x2a00001, mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 41, synthetic NO, window 0x2a00001, mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 41, synthetic NO, window 0x0, keys: 93 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 (instead of 93, I also get different values) I might have missed something very basic since I'm not very familiar with both openbox/lubuntu and the X input system. Btw.: same goes for three other special buttons on my laptop..

iTunes + External Hard Drive problem

- by Samwho

Okay, so I've always stored my music on my external hard drive and run it from there with iTunes. Recently, however, it's being a little awkward. I think it was because I accidentally tried to run a song off my hard drive when it wasn't plugged in and, as would be expected, it said it couldn't find it. So I plug the hard drive in, locate the file and off it goes. But now it won't find any of the files... When I go to the "Get Info" page on the right click menu on a song I notice it has prepended file://localhost/ to everything, so my paths look like this: "file://localhost/E:/Sam/Media/Music/[song name]" I went into the iTunes Music Library.xml file and did a search and replace for file://localhost/ and replaced it with nothing and tried opening iTunes again and it just added file://localhost/ to every file again! Anyone have any idea why it does this and how to fix it without reimporting my library?

Information I need to know as a Java Developer [on hold]

- by Woy

I'm a java developer. I'm trying to get more knowledge to become a better programmer. I've listed a number of technologies to learn. Instead of what I've listed, what technologies would you suggest to learn as well for a Junior Java Developer? I realize, there's a lot of things to study.
