• SQLAuthority News – Featuring in Call Me Maybe The Developer Way – Pluralsight Video

  - by pinaldave

  Is SQL boring? Not at all. SQL is fun – one has to know how to maximize the fun while working with SQL Server. Earlier I was invited to participate in the video Pluralsight. I am sure all of you know that I have authored 3 SQL Server Learning courses with Pluralsight – 1) SQL Server Q and A 2) SQL Server Performance Tuning and 3) SQL Server Indexing. Before I say anything I suggest all of you watch the following video. Make sure that you pay special attention after 0 minute and 36 seconds. What I can say about this. I am just fortunate to be part of the history in the making. There are more than 53 super cool celebrities in this video. In this just over 3 minute video there are so many story lines. I must congratulate director Megan and creative assistant Mari for excellent work. There are so many fun moments in this small video. Let me list my top five moments. @John_Papa ‘s dance at second 14 @julielerman playing with cute doggy The RACE between @josepheames and @bruthafish – the end is hilarious The black belt moment by @boedie @stwool relaxing on something strange! Well, this is indeed a great short film. This video demonstrates how cool is the culture of Pluralsight and how fun loving they are. A good organization provides an environment to its employees and partners to have maximum fun while they all become part of the success story. Hats off to Aaron Skonnard for producing this fun loving video. Well, after listening to this song for multiple times, I decided to give a call to Pluralsight.

• "Well, Swing took a bit of a beating this week..."

  - by Geertjan

  One unique aspect of the NetBeans community presence at JavaOne 2012 was its usage of large panels to highlight and discuss various aspects (e.g., Java EE, JavaFX, etc) of NetBeans IDE usage and tools. For example, here's a pic of one of the panels, taken by Markus Eisele: Above you see me, Sean Comerford from ESPN.com, Gerrick Bivins from Halliburton, Angelo D'Agnano and Ioannis Kostaras from the NATO Programming Center, and Çagatay Çivici from PrimeFaces. (And Tinu Awopetu was also on the panel but not in the picture!) On one of those panels a remark was made which has kind of stuck with me. Henry Arousell, a member of the "NetBeans Platform Discussion Panel", who works on accounting software in Sweden, together with Thomas Boqvist, who was also at JavaOne, said, a bit despondently, I thought, the following words at the start of the demo of his very professional looking accounting software: "Well, Swing took a bit of a beating this week..." That remark comes in the light of several JavaFX sessions held at JavaOne, together with many sessions from the web and mobile worlds making the argument that the browser, tablet, and mobile platforms are the future of all applications everywhere. However, then I had another look at the list of Duke's Choice Award winners: http://www.oracle.com/us/corporate/press/1854931 OK, there are 10 winners of the Duke's Choice Award this year. Three of them (JDuchess, London Java Community, Student Nokia Developer Group) are not awards for software, but for people or groups. So, that leaves seven awards. Three of them (Hadoop, Jelastic, and Parleys) are, in one way or another, some kind of web-oriented solution, though both Hadoop and Jelastic are broader than that, but are service-oriented solutions, relating to cloud technologies. That leaves four others: NATO air defense software, Liquid Robotics software, AgroSense software, and UNHCR Refugee Registration software. All these are, on the software level, Java desktop solutions that, on the UI layer, make use of Java Swing, together with LuciadMaps (NATO), GeoToolkit (AgroSense), and WorldWind (Liquid Robotics). (And, it went even further than that, i.e., this is not passive usage of Swing but active and motivated: Timon Veenstra, during his AgroSense demo, said "There are far more Swing applications out there than we seem to think. Web developers just make more noise." And, during his Liquid Robotics demo, James Gosling said: "Not everything can be done in HTML.") Seems to me that Java Swing was the enabler of more Duke's Choice Award winners this year than any other UI-oriented Java technology. Now, I'm not going to interpret that one way or another, since I've noticed that interpretations of facts tend to validate some underlying agenda. Take any fact anywhere and you can interpret it to prove whatever opinion you're already holding to be true. Therefore, no interpretation from me. Simply stating the fact that Swing, far from taking a beating during JavaOne 2012, was a more significant user interface enabler of Duke's Choice Award winners than any other Java user interface technology. That's not an interpretation, but a fact.

  BPM Process Accelerator Packs – Update | Pat Shepherd Architect Pat Shepherd shares several resources relevant to the new Oracle Process Accelerators for Oracle Business Process Management. Oracle BI EE Management Pack Now Available for Oracle Enterprise Manager 12cR2 | Mark Rittman A handy and informative overview from Oracle ACE Director Mark Rittman. WebSockets on WebLogic Server | Steve Button "As there's no standard WebSocket Java API at this point, we've chosen to model the API on the Grizzly WebSocket API with some minor changes where necessary," says James "Buttso" Buttons. "Once the results of JSR-356 (Java API for WebSocket) becomes public, we'll look to implement and support that." Oracle Reference Architecture: Software Engineering This document from the IT Strategies from Oracle library focuses on integrated asset management and the need for efffective asset metadata management to insure that assets are properly tracked and reused in a manner that provides a holistic functional view of the enterprise. The tipping point for cloud management is nigh | Cloud Computing - InfoWorld "Businesses typically don't think too much about managing IT resources until they become too numerous and cumbersome to deal with on an ad hoc basis—a point many companies will soon hit in their adoption of cloud computing." — David Linthicum DevOps Basics: Track Down High CPU Thread with ps, top and the new JDK7 jcmd Tool | Frank Munz "The approach is very generic and works for WebLogic, Glassfish or any other Java application," say Frank Munz. "UNIX commands in the example are run on CentOS, so they will work without changes for Oracle Enterprise Linux or RedHat. Creating the thread dump at the end of the video is done with the jcmd tool from JDK7." Frank has captured the process in the posted video. OIM 11g R2 UI customization | Daniel Gralewski "OIM user interface customizations are easier now, and they survive patch applications--there is no need to reapply them after patching," says Fusion Middleware A-Team member Daniel Gralewski. "Adding new artifacts, new skins, and plugging code directly into the user interface components became an easier task." Daniel shows just how easy in this post.

Although this article focuses on inbound OCSP validation using OCSP, Oracle WebLogic Server 12c also supports outbound OCSP validation. Leveraging Oracle Scorecard and Strategy Management for Everyday BI Needs "Oracle Scorecard and Strategy Management (OSSM) is built-upon the premise that a scorecard system should not be separate from the BI system, like many comparable tools are today," says author Kevin McGinely. "Instead of a separate application with its own data, its own data definitions, and its own front-end, Oracle made the choice to integrate OSSM directly into OBIEE." Applying BI for personal productivity recognition and gamification | Capgemini Oracle Blog "It is quite obvious that if you want people to participate you need an appealing and intuitive user interface," says Capgemini's Henk Vermeulen in this interesting exploration of gamification in the enterprise.

• Has anyone managed to build php5-xapian on Ubuntu 12.04?

  - by jetboy

  As Xapian's been dropped from the Ubuntu repositories, I'm attempting to build my own .deb from the instructions here: http://article.gmane.org/gmane.comp.search.xapian.general/8855 http://beeznest.wordpress.com/2011/07/06/howto-build-your-own-binaries-of-php-xapian-bindings-for-debian/ I can only get things to progress beyond the first few seconds by leaving out 'rm debian/control', but if I do, it looks as if the Python and Ruby bindings are building and passing their versions of smoketest correctly. However, the PHP part of the build is failing with this error: /home/charlie/xapian-bindings-1.2.8/php/smoketest.php:38: include(xapian.php): failed to open stream: No such file or directory FAIL: smoketest.php There's a xapian.php file in /home/charlie/xapian-bindings-1.2.8/php/php5/ but if I copy it to /home/charlie/xapian-bindings-1.2.8/php/ or change the path to it in smoketest.php, the build fails right near the start with: dpkg-source: error: aborting due to unexpected upstream changes Unfortunately I'm out of my comfort zone building from source. Anyone got any ideas? Edit post James' answer: Builds fine if I follow instructions exactly. I built it on a test VM initially, but that didn't build the PHP package as PHP itself wasn't installed. Obvious gotcha, but worth mentioning. Installing generated the following error: Setting up php5-xapian (1.2.8-1) ... Processing triggers for libapache2-mod-php5 ... dpkg (subprocess): unable to execute installed post-installation script (/var/lib/dpkg/info/libapache2-mod-php5.postinst): Permission denied ssion denied dpkg: error processing libapache2-mod-php5 (--install): subprocess installed post-installation script returned error exit status 2 Errors were encountered while processing: libapache2-mod-php5 It's only a script for restarting Apache. Stopping Apache before running sudo dpkg -i php5-xapian_*.deb prevents the error. Xapian now shows up in phpinfo(). Job done. Thanks.

• I can play "test" sounds, but no other audio works

  - by Callum

  I'm running Windows XP, and last night my PC was infected by a frustrating virus (one of those viruses that won't let you open virus checkers, etc). I finally killed it 2 hours later, but it involved some heavy duty anti-dote. One side effect is my audio is now gone. Except it's not entirely gone, because when I open the Realtek HD Audio Manager in the task bar, I can play all the "test" sounds. The speakers, the sound card, etc, are therefore working fine. But things like YouTube or Windows Media Player, there's no sound. I'm guessing there's a setting that needs to be reconfigured somewhere.. but where? Maybe relevant: One thing I did do last night was "play" with the system registry. Any help would be greatly appreciated. Thanks. SOLVED! The two hour battle with my computer virus resulted in my computer permanently thinking it was in Safe Mode, regardless of how it booted up. I was able to "fix" this by following the post by hsandler in this thread: http://www.petri.co.il/forums/showthread.php?t=23032&page=2 I then rebooted.. and let me tell you, the Windows Startup music has never sounded so sweet. Thanks to all, especially James, whose advice gave me a major clue as to what the problem was.

• SFTP, Chroot problems on Redhat

  - by Curtis_w

  I'm having problems setting up sftp with a ChrootDirectory. I've done an equivalent setup on other distros, but for some reason I cannot get it to work on a Redhat AMI. The changes to my sshd_config file are: Subsystem sftp internal-sftp Match Group ftponly PasswordAuthentication yes X11Forwarding no ChrootDirectory %h ForceCommand internal-sftp AllowTcpForwarding no I have the concerned usere's homes at /home/user, owned by root. After connecting with a user in the ftponly group, I'm dropped into / without permissions for anything, and am unable to do anything. sftp bob@localhost Connecting to localhost... bob@localhost's password: sftp> pwd Remote working directory: / I can connect normally with users not in the ftponly group. openssh version 5.3 I've experimented with different permissions, as well as having users own their own home directory (gives a Write failed: Broken pipe error), and so far, nothing has seemed to work. I'm sure it's a permissions error, or something equally as trivial, but at this point my eyes are beginning to glaze over, and any help would be greatly appreciated. EDIT: James and Madhatter, thanks for clarifying. I was confused by chroot dropping me in /... just didn't think through it properly. I've added the appropriate directories and permissions to get read access. One other key part was enabling write access to chrooted homes: setsebool -P ssh_chroot_rw_homedirs on in order to get write access. I think I'm all set now. Thanks for the help.

• Using Truecrypt to secure mySQL database, any pitfalls?

  - by Saul

  The objective is to secure my database data from server theft, i.e. the server is at a business office location with normal premises lock and burglar alarm, but because the data is personal healthcare data I want to ensure that if the server was stolen the data would be unavailable as encrypted. I'm exploring installing mySQL on a mounted Truecrypt encrypted volume. It all works fine, and when I power off, or just cruelly pull the plug the encrypted drive disappears. This seems a load easier than encrypting data to the database, and I understand that if there is a security hole in the web app , or a user gets physical access to a plugged in server the data is compromised, but as a sanity check , is there any good reason not to do this? @James I'm thinking in a theft scenario, its not going to be powered down nicely and so is likely to crash any DB transactions running. But then if someone steals the server I'm going to need to rely on my off site backup anyway. @tomjedrz, its kind of all sensitive, individual personal and address details linked to medical referrals/records. Would be as bad in our field as losing credit card data, but means that almost everything in the database would need encryption... so figured better to run the whole DB in an encrypted partition. If encrypt data in the tables there's got to be a key somewhere on the server I'm presuming, which seems more of a risk if the box walks. At the moment the app is configured to drop a dump of data (weekly full and then deltas only hourly using rdiff) into a directory also on the Truecrypt disk. I have an off site box running WS_FTP Pro scheduled to connect by FTPs and synch down the backup, again into a Truecrypt mounted partition.

This is what I have so far: #!/bin/sh i=/sbin/iptables # Flush all rules $i -F $i -X # Setup default filter policy $i -P INPUT DROP $i -P OUTPUT DROP $i -P FORWARD DROP # Respond to ping requests $i -A INPUT -p icmp --icmp-type any -j ACCEPT # Force SYN checks $i -A INPUT -p tcp ! --syn -m state --state NEW -j DROP # Drop all fragments $i -A INPUT -f -j DROP # Drop XMAS packets $i -A INPUT -p tcp --tcp-flags ALL ALL -j DROP # Drop NULL packets $i -A INPUT -p tcp --tcp-flags ALL NONE -j DROP # Stateful inspection $i -A INPUT -m state --state NEW -p tcp --dport 22 -j ACCEPT # Allow established connections $i -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # Allow unlimited traffic on loopback $i -A INPUT -i lo -j ACCEPT $i -A OUTPUT -o lo -j ACCEPT # Open nginx $i -A INPUT -p tcp --dport 443 -j ACCEPT $i -A INPUT -p tcp --dport 80 -j ACCEPT # Open SSH $i -A INPUT -p tcp --dport 22 -j ACCEPT However I've locked down my outgoing connections and it means I can't resolve any DNS. How do I allow that? Also, any other feedback is appreciated. James

• TFS Build errors TF224003, TF215085, TF215076

  - by iamdudley

  Hi, I am using TFS2008 and VS2008. I run nightly builds for about 20 applications using one build agent and the builds are scheduled for either 1am or 2am. Most of the build succeed, however 6 of them fail regularly with similar errors. The errors are either the first two below, or the third one by itself: TF215085: An error occurred while connecting to agent \xxxx\BUILDMACHINE: TF215076: Team Foundation Build on computer BUILDMACHINE (port 9191) is not responding. (Detail Message: The request was aborted: The operation has timed out.) 11/04/2010 2:10:10 AM TF224003: An exception occurred on the build computer BUILDMACHINE: The build (vstfs:///Build/Build/2632) has already completed and cannot be started again.. TF215085: An error occurred while connecting to agent \yyyyy\BA_WKSTFSBUILD: Team Foundation services are not available from server srvtfs. Technical information (for administrator): The operation has timed out It looks to me like some kind of communication error, maybe the port gets over loaded - can this happen? Should I spread the builds out a bit more? In the build definition it says "Queue the build on the default build agent at", so I figured if I scheduled them to start at the same time they would be queued and occur sequentially. Most of the suggestions I've found online for these errors are for all or nothing scenarios where no builds work at all whereas my problem is most build but some consistently do not. Judging by the dates of the last successful builds of these 6 failing builds I believe it is the same 6 failing every night. (I'm editing the build definitions now to keep the failed builds so I can get some more info on the problem) Any help on this would be much appreciated. James.

• .NET "must-have" development tools

  - by nzpcmad

  James Avery wrote a classic article a while back entitled Ten Must-Have Tools Every Developer Should Download Now which is a companion to Visual Studio Add-Ins Every Developer Should Download Now and Scott Hanselman has an excellent list on his blog but if you were on a desert island and were only allowed three .NET development tools which ones would you pick? Update: Assuming you already have an IDE like Visual Studio ... Update (5) : Up to 08/01 : The current state of play: Reflector 13 Resharper 9 NUnit + TestDriven.Net 7 Refactor Pro 4 Process Explorer (other Sysinternals) 3 SnippetCompiler 3 CodeRush 3 MSDN Library 2 LinqPad 2 Cruisecontrol.net 2 VMWare 2 RhinoMocks 2 Fiddler 2 PowerShell 2 PowerCommands for VS 2008 1 Sandcastle 1 SQL Profiler 1 Redgate ANTS profiler 11 NCover 1 VisualSVN 1 Rubber Ducky 1 WinMerge 1 NAnt 1 ViEmu 1 AnkhSVN 1 dotTrace Profiler 1 BeyondCompare 1 DPack VS Plugin 1 WCF Trace Viewer (SDK) 1 xUnit.net 1 SourceGear DiffMerge 1 Ghostdoc 1 Expression Studio 1 XAML Pad 1 KaXaml 1 Blender for 3D modeling 1 Snoop a WPF tool 1 DiffMerge 1 DPack 1 NDepend 1 Kodos 1 WatiN 1 HTTPWatch Basic Edition 1 Paint.Net 1 Mole For VS 1 What I find particularly interesting about this is that "NUnit + TestDriven.Net " is right up there in third place which shows the growing emphasis on testing as an integral part of the development process rather than as an adjunct which is simply bolted on. And I'm somewhat perplexed that Codesmith didn't receive a single vote?

• Top-Rated JavaScript Blogs

  I am currently trying to find some blogs that talk (almost solely) on the JavaScript Language, and this is due to the fact that most of the time, bloggers with real life experience at work or at home development can explain more clearly and concisely certain quirks and hidden features than most 'Official Language Specifications' Below find a list of blogs that are JavaScript based (will update the list as more answers flow in): DHTML Kitchen, by Garrett Smith Robert's Talk, by Robert Nyman EJohn, by John Resig (of jQuery) Crockford's JavaScript Page, by Douglas Crockford Dean.edwards.name, by Dean Edwards Ajaxian, by various (@Martin) The JavaScript Weblog, by various SitePoint's JavaScript and CSS Page, by various AjaxBlog, by various Eric Lippert's Blog, by Eric Lippert (talks about JScript and JScript.Net) Web Bug Track, by various (@scunliffe) The Strange Zen Of JavaScript , by Scott Andrew Alex Russell (of Dojo) (@Eran Galperin) Ariel Flesler (@Eran Galperin) Nihilogic, by Jacob Seidelin (@llimllib) Peter's Blog, by Peter Michaux (@Borgar) Flagrant Badassery, by Steve Levithan (@Borgar) ./with Imagination, by Dustin Diaz (@Borgar) HedgerWow (@Borgar) Dreaming in Javascript, by Nosredna spudly.shuoink.com, by Stephen Sorensen Yahoo!

• nHibernate, Automapping and Chained Abstract Classes

  - by Mr Snuffle

  I'm having some trouble using nHibernate, automapping and a class structure using multiple chains of abstract classes It's something akin to this public abstract class AbstractClassA {} public abstract class AbstractClassB : AbstractClassA {} public class ClassA : AbstractClassB {} When I attempt to build these mappings, I receive the following error "FluentNHibernate.Cfg.FluentConfigurationException was unhandled Message: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail. Database was not configured through Database method." However, if I remove the abstract keyword from AbstractClassB, everything works fine. The problem only occurs when I have more than one abstract class in the class hierarchy. I've manually configured the automapping to include both AbstractClassA and AbstractClassB using the following binding class public class BindItemBases : IManualBinding { public void Bind(FluentNHibernate.Automapping.AutoPersistenceModel model) { model.IncludeBase<AbstractClassA>(); model.IncludeBase<AbstractClassB>(); } } I've had to do a bit of hackery to get around this, but there must be a better way to get this working. Surely nHibernate supports something like this, I just haven't figured out how to configure it right. Cheers, James

• Reachability sometimes fails, even when we do have an internet connection

  - by stoutyhk

  Hi I've searched but can't see a similar question. I've added a method to check for an internet connection per the Reachability example. It works most of the time, but when installed on the iPhone, it quite often fails even when I do have internet connectivity (only when on 3G/EDGE - WiFi is OK). Basically the code below returns NO. If I switch to another app, say Mail or Safari, and connect, then switch back to the app, then the code says the internet is reachable. Kinda seems like it needs a 'nudge'. Anyone seen this before? Any ideas? Many thanks James + (BOOL) doWeHaveInternetConnection{ BOOL success; // google should always be up right?! const char *host_name = [@"google.com" cStringUsingEncoding:NSASCIIStringEncoding]; SCNetworkReachabilityRef reachability = SCNetworkReachabilityCreateWithName(NULL, host_name); SCNetworkReachabilityFlags flags; success = SCNetworkReachabilityGetFlags(reachability, &flags); BOOL isAvailable = success && (flags & kSCNetworkFlagsReachable) && !(flags & kSCNetworkFlagsConnectionRequired); if (isAvailable) { NSLog(@"Google is reachable: %d", flags); }else{ NSLog(@"Google is unreachable"); } return isAvailable; }

• Nested dereferencing arrows in Perl: to omit or not to omit?

  - by DVK

  In Perl, when you have a nested data structure, it is permissible to omit de-referencing arrows to 2d and more level of nesting. In other words, the following two syntaxes are identical: my $hash_ref = { 1 => [ 11, 12, 13 ], 3 => [31, 32] }; my $elem1 = $hash_ref->{1}->[1]; my $elem2 = $hash_ref->{1}[1]; # exactly the same as above Now, my question is, is there a good reason to choose one style over the other? It seems to be a popular bone of stylistic contention (Just on SO, I accidentally bumped into this and this in the space of 5 minutes). So far, none of the usual suspects says anything definitive: perldoc merely says "you are free to omit the pointer dereferencing arrow". Conway's "Perl Best Practices" says "whenever possible, dereference with arrows", but it appears to only apply to the context of dereferencing the main reference, not optional arrows on 2d level of nested data structures. "MAstering Perl for Bioinfirmatics" author James Tisdall doesn't give very solid preference either: "The sharp-witted reader may have noticed that we seem to be omitting arrow operators between array subscripts. (After all, these are anonymous arrays of anonymous arrays of anonymous arrays, etc., so shouldn't they be written [$array-[$i]-[$j]-[$k]?) Perl allows this; only the arrow operator between the variable name and the first array subscript is required. It make things easier on the eyes and helps avoid carpal tunnel syndrome. On the other hand, you may prefer to keep the dereferencing arrows in place, to make it clear you are dealing with references. Your choice." Personally, i'm on the side of "always put arrows in, since itg's more readable and obvious tiy're dealing with a reference".

• Detect if any USB drive is detected or if not using WinForm Application in Visual C#

  - by Pavan Kumar

  I want to do the following things in my application 1) I want to display whether any USB drive is inserted or not in my application to prompt the user to insert a USB drive. I just want to notify the user if any USB dirve is inserted else prompt him to insert one using a label or something (i want to avoid messagebox as it will keep appearing whenever a device is inserted or removed. It will be irritating for the end user) in my Visual C# WinForm Application. If any USB drive is present display "USB drive detected" in the label. The user may add one or more USB sticks but the status will remain same. When there is none then the status of the label will change to "No USB drives found.Please insert a USB drive". 2) When one or more USB drive is added the volume name with the drive letter for example "James(F:)" is added to the Combobox list. The combobox list also needs to remove the entry for the USB drive added in the list automatically when it is removed . So when there is no USB the list should be empty and the label will again prompt user to insert a USB stick or drive.

• Are Django template tags cached?

  - by thebossman

  I have gone through the (painful) process of writing a custom template tag for use in Django. It is registered as an inclusion_tag so that it renders a template. However, this tag breaks as soon as I try to change something. I've tried changing the number of parameters and correspondingly changing the parameters when it's called. It's clear the new tag code isn't being loaded, because an error is thrown stating that there is a mismatch in the number of parameters, and it's evident that it's attempting to call the old function. The same problem occurs if I try to change the name of the template being rendered and correspondingly change the name of the template on disk. It continues to try to call the old template. I've tried clearing old .pyc files with no luck. Overall, the system is acting as though it's caching the template tags, likely due to the register command. I have dug through endless threads trying to find out if this is so, but all could find it James Bennett stating here that register doesn't do anything. Please help!
