• Fast Data Executive Round Table FY14 event kit

  - by JuergenKress

  We are very interested to run joint marketing events jointly with you as our partners! At our SOA Community Workspace (SOA Community membership required) you can find a new Fast Data Executive Round Table FY14 event kit. This event is designed at senior IT and executives level for the purposes of education, awareness, and thought leadership around the subject of big data; and a specific flavor of big data - Fast Data - that has begun to spark the imagination of many Oracle customers. Fast Data is not new. It’s a term that was invented initially by Ovum’s Tony Baer as a way to represent the collection of ‘high velocity’ solutions with respect to the big data. For Oracle, the Fast Data campaign in FY13 began as a way to tie a broader set of solutions together (SOA/Business Process Management, Data Integration and Business Analytics) under a set of use cases focused on real-time, high velocity data. It has helped to give Oracle a leap-frog advantage over many of the niche integration vendors (i.e. Informatica, Pega, Tibco, Software AG, Terracotta) who haven’t been able to address these types of end-to-end use cases which rely on the combination of filtering, in-memory data processing, correlation, real-time data movement and transformation, end-to-end analytics, and business process management. Only Oracle can address all the dimensions of fast data, and only Oracle can provide a set of engineered solutions to address this space. This event is designed to continue that thought leadership momentum and raise the awareness about what Oracle Fast Data solutions are designed to solve. It’s designed to highlight real customer solutions and articulate the business benefits that fast data can address. This is not an event that gets into the esoteric technical standards of Hadoop, NoSQL, and in-memory data grids. This is an event that instead gets into the heart of business problems that big data has left un-addressed and charts the path for next steps in fast data. Get the Fast Data Executive Round Table FY14 event kit here. Support marketing campaigns We can support such events by: Oracle speakers - contact your partner manager Marketing budget - contact your A&C marketing manager Event location - free use of Oracle Customer Visitor Centers conference rooms Promote your event at events.oracle.com: http://tinyurl.com/eventspecialized E-Blast: invite customers to your event – contact your A&C marketing manager For additional marketing kits e.g for Business Process Managementplease visit our SOA Community Workspace.

• Measure Total Bandwidth for Billing

  - by TonyZ

  I am setting up a new network which customers will host their applications on. It needs to be able to scale out to a few hundred servers and each server will have several VMs on it. Right now in my test environment, after the telco router, we are using a Linux router/firewall which is then connected to a Layer 2 switch. Could be a layer 3 in the future. I need to track total bandwidth per VM for each machine, and I need to do it in a way that it is not part of the VM. Each VM will have a private class ip address which is Natted by the gateway, or we may eventually run more than firewall/reverse proxy off a layer 3 switch. So my thinking is that I can do it off of a promiscuous port on the switches, or at the gateway firewall. I would like to have an out of the box solution, preferably open source. Does anyone have suggestions on the easiest way to set this up, and the easiest tool to use. I have looked at the web sites for Nagios, Zenoss, Zabbix, ntops on the firewall, etc. It is hard to ascertain just from the web sites if they do exactly this or not. Obviously, performance is also somewhat key here. Anything running on the gateway should not drag it down doing traffic accounting. Thanks for any thoughts. Tony Zakula

• JavaOne Tutorial Report - JavaFX 2 – A Java Developer’s Guide

  - by Janice J. Heiss

  Oracle Java Technology Evangelist Stephen Chin and Independent Consultant Peter Pilgrim presented a tutorial session intended to help developers get a handle on JavaFX 2. Stephen Chin, a Java Champion, is co-author of the Pro JavaFX Platform 2, while Java Champion Peter Pilgrim is an independent consultant who works out of London.NightHacking with Stephen ChinBefore discussing the tutorial, a note about Chin’s “NightHacking Tour,” wherein from 10/29/12 to 11/11/12, he will be traveling across Europe via motorcycle stopping at JUGs and interviewing Java developers and offering live video streaming of the journey. As he says, “Along the way, I will visit user groups, interviewing interesting folks, and hack on open source projects. The last stop will be the Devoxx conference in Belgium.”It’s a dirty job but someone’s got to do it. His trip will take him from the UK through the Netherlands, Germany, Switzerland, Italy, France, and finally to Devoxx in Belgium. He has interviews lined up with Ben Evans, Trisha Gee, Stephen Coulebourne, Martijn Verburg, Simon Ritter, Bert Ertman, Tony Epple, Adam Bien, Michael Hutterman, Sven Reimers, Andres Almiray, Gerrit Grunewald, Bertrand Boetzmann, Luc Duponcheel, Stephen Janssen, Cheryl Miller, and Andrew Phillips. If you expect to be in Chin’s vicinity at the end of October and in early November, by all means get in touch with him at his site and add your perspective. The more the merrier! Taking the JavaFX PlungeNow to the business at hand. The “JavaFX 2 – A Java Developer’s Guide” tutorial introduced Java developers to the JavaFX 2 platform from the perspective of seasoned Java developers. It demonstrated the breadth of the JavaFX APIs through examples that are built out in the course of the session in an effort to present the basic requirements in using JavaFX to build rich internet applications. Chin began with a quote from Oracle’s Christopher Oliver, the creator of F3, the original version of JavaFX, on the importance of GUIs:“At the end of the day, on the one hand we have computer systems, and on the other, people. Connecting them together, and allowing people to interact with computer systems in a compelling way, requires graphical user interfaces.”Chin explained that JavaFX is about producing an immersive application experience that involves cross-platform animation, video and charting. It can integrate Java, JavaScript and HTML in the same application. The new graphics stack takes advantage of hardware acceleration for 2D and 3D applications. In addition, we can integrate Swing applications using JFXPanel.He reminded attendees that they were building JavaFX apps using pure Java APIs that included builders for declarative construction; in addition, alternative languages can be used for simpler UI creation. In addition, developers can call upon alternative languages such as GroovyFX, ScalaFX and Visage, if they want simpler UI creation. He presented the fundamentals of JavaFX 2.0: properties, lists and binding and then explored primitive, object and FX list collection properties. Properties in JavaFX are observable, lazy and type safe. He then provided an example of property declaration in code.  Pilgrim and Chin explained the architectural structure of JavaFX 2 and its basic properties:JavaFX 2.0 properties – Primitive, Object, and FX List Collection properties. * Primitive Properties* Object Properties* FX List Collection Properties* Properties are:– Observable– Lazy– Type SafeChin and Pilgrim then took attendees through several participatory demos and got deep into the weeds of the code for the two-hour session. At the end, everyone knew a lot more about the inner workings of JavaFX 2.0.

• P90X or How I Stopped Worrying and Love Exercise

  - by Matt Christian

  Last Wednesday, after many UPS delivery failures, I received P90X in the mail.  P90X is a series of DVD's and a nutrition guide you use to shed pounds and gain muscle.  Odds are you've seen the infomercial on TV at some point if you watch a little tube now and again.  I started last Thursday and am still standing to tell this tale. At it's core, P90X is a 12 DVD set of exercise videos.  Each video is comprised of a different workout routine that typically last around an hour (some up to 1 1/2 hours).  Every day you are supposed to do one of the workouts which are different every day (sometimes you may repeat a shorter 6 min workout dedicated to abs twice a week).  There are different 'programs' focused on different areas, for weight loss you do the Lean Program, standard weight loss and muscle gain do the Regular Program, and for those hardcore health-nuts, the Insane Program (which consists of 2 - 1 hour long exercises per day).  Each Program has a different set of workouts per week which you repeat for 3 weeks, followed by a 'Relaxation Week' which is essentially a slightly different order.  After the month of workouts is over, you've finished 1 phase out of 3.  P90X takes 90 days, split into 3 Phases (1 phase per month).  Every phase has a different workout order which is also focused on different areas (Weight Loss, Muscle Gain, etc...)  With the DVD's you also get a small glossy book of about 100 pages detailing the different workouts and the different programs as well as a sample workout to see if you're even ready to start P90X. The second part of P90X, which can also be considered the 'core' (actually the other half of the core) is the nutrition guide that is included.  The Nutrition Guide is a book similar to the one that defines the exercises (about 100 glossy pages) though it details foods you should eat, the amounts, and a number of healthy (and tasty!) recipes.  The guide is split up into 3 phases as well, promoting high protein and low carb/dairy at during Phase 1, and levelling off through to Phase 3 where you have a relatively balanced amount of every food group. So after 1 week where am I?  I've stuck quite close to the nutrition guide (there isn't 'diet food' in here people, it's ACTUALLY food) and done my exercise every day.  I think a lot of the first week is getting into the whole idea and learning the moves performed on the DVD.  Have I lost weight?  No.  Do I feel some definition already starting to poke out?  Absolutely (no pun intended). Tony Horton (the 51-year old hulk that runs the whole thing) is very fun to listen and work along with and the 'diet' really isn't too hard to follow unless all you eat is carbs.  I've tried the gym thing and could not get motivated enough to continue going.  P90X is the first time I've ached from a workout, BEFORE starting my next workout.  For anyone interested, Google 'P90X' or 'BeachBody' to find out more information about this awesome program!

• The enterprise vendor con - connecting SSD's using SATA 2 (3Gbits) thus limiting there performance

  - by tonyrogerson

  When comparing SSD against Hard drive performance it really makes me cross when folk think comparing an array of SSD running on 3GBits/sec to hard drives running on 6GBits/second is somehow valid. In a paper from DELL (http://www.dell.com/downloads/global/products/pvaul/en/PowerEdge-PowerVaultH800-CacheCade-final.pdf) on increasing database performance using the DELL PERC H800 with Solid State Drives they compare four SSD drives connected at 3Gbits/sec against ten 10Krpm drives connected at 6Gbits [Tony slaps forehead while shouting DOH!]. It is true in the case of hard drives it probably doesn’t make much difference 3Gbit or 6Gbit because SAS and SATA are both end to end protocols rather than shared bus architecture like SCSI, so the hard drive doesn’t share bandwidth and probably can’t get near the 600MiBytes/second throughput that 6Gbit gives unless you are doing contiguous reads, in my own tests on a single 15Krpm SAS disk using IOMeter (8 worker threads, queue depth of 16 with a stripe size of 64KiB, an 8KiB transfer size on a drive formatted with an allocation size of 8KiB for a 100% sequential read test) I only get 347MiBytes per second sustained throughput at an average latency of 2.87ms per IO equating to 44.5K IOps, ok, if that was 3GBits it would be less – around 280MiBytes per second, oh, but wait a minute [...fingers tap desk] You’ll struggle to find in the commodity space an SSD that doesn’t have the SATA 3 (6GBits) interface, SSD’s are fast not only low latency and high IOps but they also offer a very large sustained transfer rate, consider the OCZ Agility 3 it so happens that in my masters dissertation I did the same test but on a difference box, I got 374MiBytes per second at an average latency of 2.67ms per IO equating to 47.9K IOps – cost of an 240GB Agility 3 is £174.24 (http://www.scan.co.uk/products/240gb-ocz-agility-3-ssd-25-sata-6gb-s-sandforce-2281-read-525mb-s-write-500mb-s-85k-iops), but that same drive set in a box connected with SATA 2 (3Gbits) would only yield around 280MiBytes per second thus losing almost 100MiBytes per second throughput and a ton of IOps too. So why the hell are “enterprise” vendors still only connecting SSD’s at 3GBits? Well, my conspiracy states that they have no interest in you moving to SSD because they’ll lose so much money, the argument that they use SATA 2 doesn’t wash, SATA 3 has been out for some time now and all the commodity stuff you buy uses it now. Consider the cost, not in terms of price per GB but price per IOps, SSD absolutely thrash Hard Drives on that, it was true that the opposite was also true that Hard Drives thrashed SSD’s on price per GB, but is that true now, I’m not so sure – a 300GByte 2.5” 15Krpm SAS drive costs £329.76 ex VAT (http://www.scan.co.uk/products/300gb-seagate-st9300653ss-savvio-15k3-25-hdd-sas-6gb-s-15000rpm-64mb-cache-27ms) which equates to £1.09 per GB compared to a 480GB OCZ Agility 3 costing £422.10 ex VAT (http://www.scan.co.uk/products/480gb-ocz-agility-3-ssd-25-sata-6gb-s-sandforce-2281-read-525mb-s-write-410mb-s-30k-iops) which equates to £0.88 per GB. Ok, I compared an “enterprise” hard drive with a “commodity” SSD, ok, so things get a little more complicated here, most “enterprise” SSD’s are SLC and most commodity are MLC, SLC gives more performance and wear, I’ll talk about that another day. For now though, don’t get sucked in by vendor marketing, SATA 2 (3Gbit) just doesn’t cut it, SSD need 6Gbit to breath and even that SSD’s are pushing. Alas, SSD’s are connected using SATA so all the controllers I’ve seen thus far from HP and DELL only do SATA 2 – deliberate? Well, I’ll let you decide on that one.

• Announcing Oracle Knowledge 8.5: Even Superheroes Need Upgrades

  - by Richard Lefebvre

  It’s no secret that we like Iron Man here at Oracle. We've certainly got stuff in common: one of the world’s largest technology companies and one of the world’s strongest technology-driven superheroes. If you've seen the recent Iron Man movies, you might have even noticed some of our servers sitting in Tony Stark’s lab. Heck, our CEO made a cameo appearance in one of the movies. Yeah, we’re fans. Especially as Iron Man is a regular guy with some amazing technology – like us. But Like all great things even Superheroes need upgrades, whether it’s their suit, their car or their spacestation. Oracle certainly has its share of advanced technology.  For example, Oracle acquired InQuira in 2011 after years of watching the company advance the science of Knowledge Management.  And it was some extremely super technology.  At that time, Forrester’s Kate Leggett wrote about it in ‘Standalone Knowledge Management Is Dead With Oracle's Announcement To Acquire InQuira’ saying ‘Knowledge, accessible via web self-service or agent UIs, is a critical customer service component for industries fielding repetitive questions about policies, procedures, products, and solutions.’  One short sentence that amounts to a very tall order.  Since the acquisition our KM scientists have been hard at work in their labs. Today Oracle announced its first major knowledge management release since its acquisition of InQuira: Oracle Knowledge 8.5. We’ve put a massively-upgraded supersuit on our KM solution because we still have bad guys to fight. And we are very proud to say that we went way beyond our original plans. So what, exactly, did we do in Oracle Knowledge 8.5? We did what any high-tech super-scientist would do. We made Oracle Knowledge smarter, stronger and faster. First, we gave Oracle Knowledge a stronger heart: Certified on Oracle technologies, including Oracle WebLogic Server, Oracle Business Intelligence, Oracle Exadata Database Machine and Oracle Exalogic Elastic Cloud. Huge scaling and performance improvements. Then we gave it a better reach: Improved iConnect functionality that delivers contextualized knowledge directly into CRM applications. Better content acquisition support across disparate sources. Enhanced Language Support including Natural Language search support for 16 Languages. Enhanced Keyword Search for 23 authoring languages, as well as enhanced out-of-the-box industry ontologies covering 14 languages. And finally we made Oracle Knowledge ridiculously smarter: Improved Natural Language Search and a new Contextual Answer Delivery that understands the true intent of each inquiry to deliver the best possible answers. AnswerFlow for Guided Navigation & Answer Delivery, a new application for guided troubleshooting and answer delivery. Knowledge Analytics standardized on Oracle’s Business Intelligence Enterprise Edition. Knowledge Analytics Dashboards optimized search and content creation through targeted, actionable insights. A new three-level language model "Global - Language - Locale" that provides an improved search experience for organizations with a global footprint. We believe that Oracle Knowledge 8.5 is the most sophisticated KM solution in existence today and we’ve worked very hard to help it fulfill the promise of KM: empowering customers and employees with deep insights wherever they need them. We hope you agree it’s a suit worth wearing. We are continuing to invest in Knowledge Management as it continues to be especially relevant today with the enterprise push for peer collaboration, crowd-sourced wisdom, agile innovation, social interaction channels, applied real-time analytics, and personalization. In fact, we believe that Knowledge Management is a critical part of the Customer Experience portfolio for success. From empowering employee’s, to empowering customers, to gaining the insights from interactions across all channels, businesses today cannot efficiently scale their efforts, strengthen their customer relationships or achieve their growth goals without a solid Knowledge Management foundation to build from. And like every good superhero saga, we’re not even close to being finished. Next we are taking Oracle Knowledge into the Cloud. Yes, we’re thinking what you’re thinking: ROCKET BOOTS! Stay tuned for the next adventure… By Nav Chakravarti, Vice-President, Product Management, CRM Knowledge and previously the CTO of InQuira, a knowledge management company acquired by Oracle in 2011

• What are the disadvantages of self-encapsulation?

  - by Dave Jarvis

  Background Tony Hoare's billion dollar mistake was the invention of null. Subsequently, a lot of code has become riddled with null pointer exceptions (segfaults) when software developers try to use (dereference) uninitialized variables. In 1989, Wirfs-Brock and Wikerson wrote: Direct references to variables severely limit the ability of programmers to re?ne existing classes. The programming conventions described here structure the use of variables to promote reusable designs. We encourage users of all object-oriented languages to follow these conventions. Additionally, we strongly urge designers of object-oriented languages to consider the effects of unrestricted variable references on reusability. Problem A lot of software, especially in Java, but likely in C# and C++, often uses the following pattern: public class SomeClass { private String someAttribute; public SomeClass() { this.someAttribute = "Some Value"; } public void someMethod() { if( this.someAttribute.equals( "Some Value" ) ) { // do something... } } public void setAttribute( String s ) { this.someAttribute = s; } public String getAttribute() { return this.someAttribute; } } Sometimes a band-aid solution is used by checking for null throughout the code base: public void someMethod() { assert this.someAttribute != null; if( this.someAttribute.equals( "Some Value" ) ) { // do something... } } public void anotherMethod() { assert this.someAttribute != null; if( this.someAttribute.equals( "Some Default Value" ) ) { // do something... } } The band-aid does not always avoid the null pointer problem: a race condition exists. The race condition is mitigated using: public void anotherMethod() { String someAttribute = this.someAttribute; assert someAttribute != null; if( someAttribute.equals( "Some Default Value" ) ) { // do something... } } Yet that requires two statements (assignment to local copy and check for null) every time a class-scoped variable is used to ensure it is valid. Self-Encapsulation Ken Auer's Reusability Through Self-Encapsulation (Pattern Languages of Program Design, Addison Wesley, New York, pp. 505-516, 1994) advocated self-encapsulation combined with lazy initialization. The result, in Java, would resemble: public class SomeClass { private String someAttribute; public SomeClass() { setAttribute( "Some Value" ); } public void someMethod() { if( getAttribute().equals( "Some Value" ) ) { // do something... } } public void setAttribute( String s ) { this.someAttribute = s; } public String getAttribute() { String someAttribute = this.someAttribute; if( someAttribute == null ) { setAttribute( createDefaultValue() ); } return someAttribute; } protected String createDefaultValue() { return "Some Default Value"; } } All duplicate checks for null are superfluous: getAttribute() ensures the value is never null at a single location within the containing class. Efficiency arguments should be fairly moot -- modern compilers and virtual machines can inline the code when possible. As long as variables are never referenced directly, this also allows for proper application of the Open-Closed Principle. Question What are the disadvantages of self-encapsulation, if any? (Ideally, I would like to see references to studies that contrast the robustness of similarly complex systems that use and don't use self-encapsulation, as this strikes me as a fairly straightforward testable hypothesis.)

• How to fix the endless printing loop bug in Nevrona Rave

  - by Sean B. Durkin

  Nevrona Designs' Rave Reports is a Report Engine for use by Embarcadero's Delphi IDE. This is what I call the Rave Endless Loop bug. In Rave Reports version 6.5.0 (VCL10) that comes bundled with Delphi 2006, there is a nortorious bug that plagues many Rave report developers. If you have a non-empty dataset, and the data rows for this dataset fit exactly into a page (that is to say there are zero widow rows), then upon PrintPreview, Rave will get stuck in an infinite loop generating pages. This problem has been previously reported in this newsgroup under the following headings: "error: generating infinite pages"; Hugo Hiram 20/9/2006 8:44PM "Rave loop bug. Please help"; Tomas Lazar 11/07/2006 7:35PM "Loop on full page of data?"; Tony Chistiansen 23/12/2004 3:41PM reply to (3) by another complainant; Oliver Piche "Endless lopp print bug"; Richso 9/11/2004 4:44PM In each of these postings, there was no response from Nevrona, and no solution was reported. Possibly, the problem has also been reported on an allied newsgroup (nevrona.public.rave.reports.general), to wit: 6. "Continuously generating report"; Jobard 20/11/2005 Although it is not clear to me if (6) is the Rave Endless loop bug or another problem. This posting did get a reply from Nevrona, but it was more in relation to multiple regions ("There is a problem when using multiple regions that go over a page-break.") than the problem of zero widows.

• ildasm and dynamic exe files

  - by TonyNeallon

  Hi There, I am trying to create an application can modify properties in IL to create a slightly different executable. E.g Client A runs app and a label on the WinForm label Reads "Client A:". Client B runs the app and Label Says "Client B". Easy I know using config files or resource files but thats not an option for this project. The Main program needs to be able to generate .exe file dynamically based on some form fields entered by user. My solution was to create a standalone executable that contained all the elements which I needed to make dynamic. I then used ildasm to generate the IL and thought that I could use this IL and substitute tags for the elements i wanted to make dynamic. I could then replace those tags at runtime after user filled the form using regex etc. The problem is, the if i re save the IL file generated by ILDASM as an exe and try to run it. I just launches console and does nothing. Am I going about this the wrong way? I didnt want to delve into Reflection as the dynamic .exe is a really simple one and I thought reverse engineering IL with ildasm would be the quickest way. You thoughts and pointers are much appreciated. Tony

• Making RDoc Ruby Gem Default on Mac OS X

  - by jkale

  Hey all, I've recently installed RDoc version (2.4.3) through Ruby gems to replace the one shipped with Mac OS X (version 1.0.1). Unfortunately, I can still only use RDoc 1.0.1 when I call run "rdoc" at the command line. rdoc -v returns: RDoc V1.0.1 - 20041108 I tried amending the $PATH variable to point the first entry to the RDoc 2.4.3 folder but no luck. I couldn't find anything about this online either, so I thought I'd ask here. Cheers! Update: Running "gem list -d --version 1.0.1 rdoc" returns: *** LOCAL GEMS *** rdoc (2.4.3) Authors: Eric Hodel, Dave Thomas, Phil Hagelberg, Tony Strauss Rubyforge: http://rubyforge.org/projects/rdoc Homepage: http://rdoc.rubyforge.org Installed at: /usr/local/lib/ruby/gems/1.8 RDoc is an application that produces documentation for one or more Ruby source files Therefore, it's definitely the Mac OSX version of RDoc that's interfering with the Gems version. Update 2: I found out, using: `bash --debugger rdoc` that the old version of RDoc was in /opt/local/bin. I deleted it and added my gems directory to my $PATH `export PATH=/usr/local/lib/ruby/gems/1.8/gems/` I now have a fresh working copy of the latest RDoc!

• Rails does not display error messages on a form in a custom method

  - by slythic

  Hi all, I've created a custom method called checkout in my app. I create an order (which is done my adding products to my "cart"), assign it to my client, and then I head to my checkout screen where I confirm the items and enter their customer order number and complete the order (submit). Everything works great except that it doesn't display error messages. I'm able to display a flash error notice (seen in complete_order method) when things go wrong but it doesn't specify the details like a normal form would. The error messages should appear if the customer order number is not unique for that client. Below is the custom method (checkout) related code. Order Model: validates_uniqueness_of :customer_order_number, :scope => :client_id Orders_controller: def checkout @order = current_order end def complete_order @order = current_order respond_to do |format| if @order.update_attributes(params[:order]) @order.complete #sets submitted datetime and state to 'complete' flash[:notice] = 'Thank you! Your order is being processed.' format.html { redirect_to( products_path ) } format.xml { head :ok } else flash[:error] = 'Please review your items' #added to confirm an error is present format.html { redirect_to( checkout_path ) } format.xml { render :xml => @order.errors, :status => :unprocessable_entity } end end end And the form in the checkout view: <% form_for @order, :url => { :controller => "orders", :action => "complete_order" } do |f| %> <%= f.error_messages %> <%= f.text_field :customer_order_number, :label => "Purchase Order Number" %> <p> <%= f.submit 'Complete Order', :confirm => 'Are you sure?' %> <small> or <%= link_to 'cancel', current_cart_path %></small> </p> <% end %> Any idea how I can display the specific error messages? Thank you in advance! -Tony

• Let multiple highcharts charts appear automatically from mysql data

  - by martini1993

  I have the following problem. I want to make multiple Highcharts webcharts appear automatically based on the data from the database. Let's say we have the following database: ___________________________________________________________________ | | | | | | | | Year | Month | ID | Name User | Wins | Losses | |_______|___________|______|_______________|____________|__________| | 2013 1 21 Tony Stark 3 12 | | 2013 1 52 Bruce Wayne 5 4 | | 2013 1 76 Clark Kent 9 5 | |__________________________________________________________________| (This database is an example, there are a lot more rows in the real database.) And i have the following query: SELECT a.year AS year1, a.month AS month1, a.id AS id, a.name AS nameuser, a.wins AS wins, a.losses AS losses FROM Sales a WHERE a.month = 1 AND a.year = YEAR(NOW()) With this, it is very easy to hardcode a chart with Highcharts. But what I want is that there has to be a webchart per user. So instead of a single webchart with all the users in it, I want multiple charts next to each other based on the data from the database. So instead of this: http://jsfiddle.net/CWSb6/ I want this (But then next to each other): http://jsfiddle.net/DReMD/ It has to be generated automatically with php and mysql. So if there is a new user starting this month, and the new user is saved in the database, the page automatically displays the new user with the related web chart. I find this very hard to accomplish and I need some help to get to the right direction for the solution. Many thanks in advance! (Sorry for my bad english.)

• What are the best practices for storing PHP session data in a database?

  - by undefined

  I have developed a web application that uses a web server and database hosted by a web host (on the ground) and a server running on Amazon Web Services EC2. Both servers may be used by a user during a session and both will need to know some session information about a user. I don't want to POST the information that is needed by both servers because I dont want it to be visible to browsers / Firebug etc. So I need my session data to persist across servers. And I think that this means that the best option is to store all / some of the data that I need in the database rather than in a session. The easiest thing to do seems to be to keep the sessions but to POST the session_id between servers and use this as the key to lookup the data I need from a 'user_session_data' table in the database. I have looked at Tony Marston's article "Saving PHP Session Data to a database" - should I use this or will a table with the session data that I need and session_id as key suffice? What would be the downside of creating my own table and set of methods for storing the data I need in the database?

• Cant access a remote server due mistake by setting firewall rule

  - by LMIT

  I need help due a my silly mistake! So for long time i have a dedicate server hosted by register.it Usually i access remotly to this server (Windows 2008 server) by Terminal Server. Today i wanted to block one site that continually send request to my server. So i was adding a new rule in the firewall (the native firewall on windows 2008 server), as i did many time, but this time, probably i was sleeping with my brain i add a general rules that stop everything! So i cant access to the server anymore, as no any users can browse the sites, nothing is working because this rule block everything. I know that is a silly mistake, no need to tell me :) so please what i can do ? The only 1 thing that my provider let me is reboot the server by his control panel, but this not help me in any way because the firewall block me again. i have administrator username and password, so what i really can do ? there are some trick some tecnique, some expert guru that can help me in this very bad situation ?

• Sharing folder in a Virtual Private Windows Server 2008 R2 ?

  - by Triztian

  See Edit 2: Hello all, seems my involvement with computers has grown and I've found my self in the need to access a shared folder on a server. I've read some documentation and managed to set up the folder as a share, for this I created a local group and for now just one local user that has access to the share, the folder is in the public user folder and it's permissions should be (and I believe they are) read/write. The problem is that I can't connect from a remote machine I mean I don't know how the way it should be accessed, the server has a public IP and we use it also as a host to our website I don't know if that affects it though, the folder will be used as the "keeper" for the QuickBooks company files and has the database server manager installed. I've tried setting up a VPN Connection to the but no success. The server has a domain name a "http://www.example.com" that redirects to our website, I am unsure if it could be accessed that way, also the share has a location displayed when I right-click properties Heres what I've tried Setting up a VPN Connection (Windows Vista and 7) Got to the point where I got asked for credential and entered the user I created (which is not an admin) but I got a "Connection fail error 800" I suppose this is because in the domain field I entered the servers workgroup. right-click add network connection (Windows 7) Went through the wizard until I reached the point of entering the location, tried many things, the name in the share's properties(\\SOMETHING\Share), the http://www.example.com , the IP address I'm quite unfamiliar with this, so I have my guesses: Since the group and user are local they do not have access to the folder. The firewall in the server is blocking my connection. Anyways, any help and guidence is truly appreciated. EDIT 1: As @tony roth pointed out it may be a security fail, an I commented it out to management and said that that is not an issue, so please bare with me. EDIT 2: I've found out that the real question could be streamlined to "Sharing folder in a Virtual Private Server?", as thats what we have, a virtual private windows server 2008 R2, and I would like to know how to make it show like a normal folder in the client computer. Thanks again for all of your support.

• RSS Feeds currently on Simple-Talk

  - by Andrew Clarke

  There are a number of news-feeds for the Simple-Talk site, but for some reason they are well hidden. Whilst we set about reorganizing them, I thought it would be a good idea to list some of the more important ones. The most important one for almost all purposes is the Homepage RSS feed which represents the blogs and articles that are placed on the homepage. Main Site Feed representing the Homepage ..which is good for most purposes but won't always have all the blogs, or maybe it will occasionally miss an article. If you aren't interested in all the content, you can just use the RSS feeds that are more relevant to your interests. (We'll be increasing these categories soon) The newsfeed for SQL articles The .NET section newsfeed The newsfeed for Red Gate books The newsfeed for Opinion articles The SysAdmin section newsfeed if you want to get a more refined feed, then you can pick and choose from these feeds for each category so as to make up your custom news-feed in the SQL section, SQL Training Learn SQL Server Database Administration TSQL Programming SQL Server Performance Backup and Recovery SQL Tools SSIS SSRS (Reporting Services) in .NET there are...

• Algorithmia Source Code released on CodePlex

  - by FransBouma

  Following the release of our BCL Extensions Library on CodePlex, we have now released the source-code of Algorithmia on CodePlex! Algorithmia is an algorithm and data-structures library for .NET 3.5 or higher and is one of the pillars LLBLGen Pro v3's designer is built on. The library contains many data-structures and algorithms, and the source-code is well documented and commented, often with links to official descriptions and papers of the algorithms and data-structures implemented. The source-code is shared using Mercurial on CodePlex and is licensed under the friendly BSD2 license. User documentation is not available at the moment but will be added soon. One of the main design goals of Algorithmia was to create a library which contains implementations of well-known algorithms which weren't already implemented in .NET itself. This way, more developers out there can enjoy the results of many years of what the field of Computer Science research has delivered. Some algorithms and datastructures are known in .NET but are re-implemented because the implementation in .NET isn't efficient for many situations or lacks features. An example is the linked list in .NET: it doesn't have an O(1) concat operation, as every node refers to the containing LinkedList object it's stored in. This is bad for algorithms which rely on O(1) concat operations, like the Fibonacci heap implementation in Algorithmia. Algorithmia therefore contains a linked list with an O(1) concat feature. The following functionality is available in Algorithmia: Command, Command management. This system is usable to build a fully undo/redo aware system by building your object graph using command-aware classes. The Command pattern is implemented using a system which allows transparent undo-redo and command grouping so you can use it to make a class undo/redo aware and set properties, use its contents without using commands at all. The Commands namespace is the namespace to start. Classes you'd want to look at are CommandifiedMember, CommandifiedList and KeyedCommandifiedList. See the CommandQueueTests in the test project for examples. Graphs, Graph algorithms. Algorithmia contains a sophisticated graph class hierarchy and algorithms implemented onto them: non-directed and directed graphs, as well as a subgraph view class, which can be used to create a view onto an existing graph class which can be self-maintaining. Algorithms include transitive closure, topological sorting and others. A feature rich depth-first search (DFS) crawler is available so DFS based algorithms can be implemented quickly. All graph classes are undo/redo aware, as they can be set to be 'commandified'. When a graph is 'commandified' it will do its housekeeping through commands, which makes it fully undo-redo aware, so you can remove, add and manipulate the graph and undo/redo the activity automatically without any extra code. If you define the properties of the class you set as the vertex type using CommandifiedMember, you can manipulate the properties of vertices and the graph contents with full undo/redo functionality without any extra code. Heaps. Heaps are data-structures which have the largest or smallest item stored in them always as the 'root'. Extracting the root from the heap makes the heap determine the next in line to be the 'maximum' or 'minimum' (max-heap vs. min-heap, all heaps in Algorithmia can do both). Algorithmia contains various heaps, among them an implementation of the Fibonacci heap, one of the most efficient heap datastructures known today, especially when you want to merge different instances into one. Priority queues. Priority queues are specializations of heaps. Algorithmia contains a couple of them. Sorting. What's an algorithm library without sort algorithms? Algorithmia implements a couple of sort algorithms which sort the data in-place. This aspect is important in situations where you want to sort the elements in a buffer/list/ICollection in-place, so all data stays in the data-structure it already is stored in. PropertyBag. It re-implements Tony Allowatt's original idea in .NET 3.5 specific syntax, which is to have a generic property bag and to be able to build an object in code at runtime which can be bound to a property grid for editing. This is handy for when you have data / settings stored in XML or other format, and want to create an editable form of it without creating many editors. IEditableObject/IDataErrorInfo implementations. It contains default implementations for IEditableObject and IDataErrorInfo (EditableObjectDataContainer for IEditableObject and ErrorContainer for IDataErrorInfo), which make it very easy to implement these interfaces (just a few lines of code) without having to worry about bookkeeping during databinding. They work seamlessly with CommandifiedMember as well, so your undo/redo aware code can use them out of the box. EventThrottler. It contains an event throttler, which can be used to filter out duplicate events in an event stream coming into an observer from an event. This can greatly enhance performance in your UI without needing to do anything other than hooking it up so it's placed between the event source and your real handler. If your UI is flooded with events from data-structures observed by your UI or a middle tier, you can use this class to filter out duplicates to avoid redundant updates to UI elements or to avoid having observers choke on many redundant events. Small, handy stuff. A MultiValueDictionary, which can store multiple unique values per key, instead of one with the default Dictionary, and is also merge-aware so you can merge two into one. A Pair class, to quickly group two elements together. Multiple interfaces for helping with building a de-coupled, observer based system, and some utility extension methods for the defined data-structures. We regularly update the library with new code. If you have ideas for new algorithms or want to share your contribution, feel free to discuss it on the project's Discussions page or send us a pull request. Enjoy!

• Simple-Talk development: a quick history lesson

  - by Michael Williamson

  Up until a few months ago, Simple-Talk ran on a pure .NET stack, with IIS as the web server and SQL Server as the database. Unfortunately, the platform for the site hadn’t quite gotten the love and attention it deserved. On the one hand, in the words of our esteemed editor Tony “I’d consider the current platform to be a “success”; it cost $10K, has lasted for 6 years, was finished, end to end in 6 months, and although we moan about it has got us quite a long way.” On the other hand, it was becoming increasingly clear that it needed some serious work. Among other issues, we had authors that wouldn’t blog because our current blogging platform, Community Server, was too painful for them to use. Forgetting about Simple-Talk for a moment, if you ask somebody what blogging platform they’d choose, the odds are they’d say WordPress. Regardless of its technical merits, it’s probably the most popular blogging platform, and it certainly seemed easier to use than Community Server. The issue was that WordPress is normally hosted on a Linux stack running PHP, Apache and MySQL — quite a difference from our Microsoft technology stack. We certainly didn’t want to rewrite the entire site — we just wanted a better blogging platform, with the rest of the existing, legacy site left as is. At a very high level, Simple-Talk’s technical design was originally very straightforward: when your browser sends an HTTP request to Simple-Talk, IIS (the web server) takes the request, does some work, and sends back a response. In order to keep the legacy site running, except with WordPress running the blogs, a different design is called for. We now use nginx as a reverse-proxy, which can then delegate requests to the appropriate application: So, when your browser sends a request to Simple-Talk, nginx takes that request and checks which part of the site you’re trying to access. Most of the time, it just passes the request along to IIS, which can then respond in much the same way it always has. However, if your request is for the blogs, then nginx delegates the request to WordPress. Unfortunately, as simple as that diagram looks, it hides an awful lot of complexity. In particular, the legacy site running on IIS was made up of four .NET applications. I’ve already mentioned one of these applications, Community Server, which handled the old blogs as well as managing membership and the forums. We have a couple of other applications to manage both our newsletters and our articles, and our own custom application to do some of the rendering on the site, such as the front page and the articles. When I say that it was made up of four .NET applications, this might conjure up an image in your mind of how they fit together: You might imagine four .NET applications, each with their own database, communicating over well-defined APIs. Sadly, reality was a little disappointing: We had four .NET applications that all ran on the same database. Worse still, there were many queries that happily joined across tables from multiple applications, meaning that each application was heavily dependent on the exact data schema that each other application used. Add to this that many of the queries were at least dozens of lines long, and practically identical to other queries except in a few key spots, and we can see that attempting to replace one component of the system would be more than a little tricky. However, the problems with the old system do give us a good place to start thinking about desirable qualities from any changes to the platform. Specifically: Maintainability — the tight coupling between each .NET application made it difficult to update any one application without also having to make changes elsewhere Replaceability — the tight coupling also meant that replacing one component wouldn’t be straightforward, especially if it wasn’t on a similar Microsoft stack. We’d like to be able to replace different parts without having to modify the existing codebase extensively Reusability — we’d like to be able to combine the different pieces of the system in different ways for different sites Repeatable deployments — rather than having to deploy the site manually with a long list of instructions, we should be able to deploy the entire site with a single command, allowing you to create a new instance of the site easily whether on production, staging servers, test servers or your own local machine Testability — if we can deploy the site with a single command, and each part of the site is no longer dependent on the specifics of how every other part of the site works, we can begin to run automated tests against the site, and against individual parts, both to prevent regressions and to do a little test-driven development In the next part, I’ll describe the high-level architecture we now have that hopefully brings us a little closer to these five traits.

• Sea Monkey Sales & Marketing, and what does that have to do with ERP?

  - by user709270

  Tier One Defined By Lyle Ekdahl, Oracle JD Edwards Group Vice President and General Manager  I recently became aware of the latest Sea Monkey Sales & Marketing tactic. Wait now, what is Sea Monkey Sales & Marketing and what does that have to do with ERP? Well if you grew up in USA during the 50’s, 60’s and maybe a bit in the early 70’s there was a unifying media of culture known as the comic book. I was a big Iron Man fan. I always liked the troubled hero aspect of Tony Start and hey he was a technologist. This is going somewhere, just hold on. Of course comic books like most media contained advertisements. Ninety pound weakling transformed by Charles Atlas in just 15 minutes per day. Baby Ruth, Juicy Fruit Gum and all assortments of Hostess goodies were on display. The best ad was for the “Amazing Live Sea-Monkeys – The real live fun-pets you grow yourself!” These ads set the standard for exaggeration and half-truth; “…they love attention…so eager to please, they can even be trained…” The cartoon picture on the ad is of a family of royal looking sea creatures – daddy, mommy, son and little sis – sea monkey? There was a disclaimer at the bottom in fine print, “Caricatures shown not intended to depict Artemia.” Ok what ten years old knows what the heck artemia is? Well you grow up fast once you’ve been separated from your buck twenty five plus postage just to discover that it is brine shrimp. Really dumb brine shrimp that don’t take commands or do tricks. Unfortunately the technology industry is full of sea monkey sales and marketing. Yes believe it or not in some cases there is subterfuge and obfuscation used to secure contracts. Hey I get it; the picture on the box might not be the actual size. Make up what you want about your product, but here is what I don’t like, could you leave out the obvious falsity when it comes to my product, especially the negative stuff. So here is the latest one – “Oracle’s JD Edwards is NOT tier one”. Really? Definition please! Well a whole host of googleable and reputable sources confirm that a tier one vendor is large, well known, and enjoys national and international recognition. Let me see large, so thousands of customers? Oh and part of the world’s largest business software and hardware corporation? Check and check JD Edwards has that and that. Well known, enjoying national and international recognition? Oracle’s JD Edwards EnterpriseOne is available in 21 languages and is directly localized in 33 countries that support some of the world’s largest multinationals and many midsized domestic market companies. Something on the order of half the JD Edwards customer base is outside North America. My passport is on its third insert after 2 years and not from vacations. So if you don’t mind I am going to mark national and international recognition in the got it column. So what else is there? Well let me offer a few criteria. Longevity – The JD Edwards products benefit from 35+ years of intellectual property development; through booms, busts, mergers and acquisitions, we are still here Vision & innovation – JD Edwards is the first full suite ERP to run on the iPad as just one example Proven track record of execution – Since becoming part of Oracle, JD Edwards has released to the market over 20 deliverables including major release, point releases, new apps modules, tool releases, integrations…. Solid, focused functionality with a flexible, interoperable, extensible underlying architecture – JD Edwards offers solid core ERP with specialty modules for verticals all delivered on a well defined independent tools layer that helps enable you to scale your business without an ERP reimplementation A continuation plan – Oracle’s JD Edwards offers our customers a 6 year roadmap as well as interoperability with Oracle’s next generation of applications Oh I almost forgot that the expert sources agree on one additional thing, tier one may be a preferred vendor that offers product and services to you with appealing value. You should check out the TCO studies of JD Edwards. I think you will see what the thousands of customers that rely on these products to run their businesses enjoy – that is the tier one solution with the lowest TCO. Oh and if you get an offer to buy an ERP for no license charge, remember the picture on the box might not be the actual size.
