• How to manage primary key while updating [migrated]

  - by Subin Jacob

  In the following table primaryKeyColumn is primary key. To maintain the data history I always uses the values with WHERE condition(WHERE StatusColumn=1) And will set the StatusColumn to 0 if the data is edited (So that I could keep the previous data). But the problem is, if I update it to 0 , I can't insert the same key to primarykeycolumn since the column validated for primary keys. How can I manage these kind of validations? what the mistake I did in this design? primaryKeyColumn ValueColumn StatusColumn ---------------- ----------- ------------ 2 Name1 1 3 Name2 1 4 Name3 0

• TFS vs. Star Team comparison

  - by ryanabr

  I have a sales call today in which the person that I am talking to is interested in what TFS would give them over Star Team, The first thing I believe that I can say is that TFS is cheaper! Especially if you are doing MSFT development already and your team members have MSDN subscriptions as the CALs for TFS are covered in the MSDN subscription. The other thing that I noticed about Star Team was all of the references to ‘readiness’ and ‘integration’. While that is great, that means that other tools will be needed to provide the features that are already bundled with TFS like, SharePoint integration, as well as Analysis Services and Reporting Services to provide visibility on the web with reports on project health, and team velocity. Below is a quick table that I was able to throw together to answer some high level questions: Feature TFS Star Team Work Items X X Work Item custom Queries X X Customizable Work Items X Web Portal View X X Reporting X Integration Version Control X X Build Management X Integration Integrated Test Suite X Integration Cost Free for first 5 / MSDN Sub covers others $7500 / seat

• Cannot install ubuntu on Asus UX51VZ

  - by Andrey Frunt

  I removed Win8, changed partition table from GPT to MBR and installed Win7. The problem is that I don't see the grub after I installed ubuntu and only win7 boots. Any ideas? I tried to reinstall all of listed above about 5 times but with no success :( I tried both 13.04 and 13.10 UPD: I also tried Boot-Repair and it installed the grub2 for me but unfortunately only with options to run ubuntu, so I repaired bootrecord using windows tools to have an ability to run to windows. Anyway I still cannot configure the dual boot. Please help :)

• PHP security regarding login

  - by piers

  I have read a lot about PHP login security recently, but many questions on Stack Overflow regarding security are outdated. I understand bcrypt is one of the best ways of hashing passwords today. However, for my site, I believe sha512 will do very well, at least to begin with. (I mean bcrypt is for bigger sites, sites that require high security, right?) I´m also wonder about salting. Is it necessary for every password to have its own unique salt? Should I have one field for the salt and one for the password in my database table? What would be a decent salt today? Should I join the username together with the password and add a random word/letter/special character combination to it? Thanks for your help!

• Looking for reading material on application architecture with web UI

  - by toong

  I'm looking for articles (or other reading material) on the topic of fat client applications with a web UI layer. Open-source projects that use this architecture would be very interesting too. Such an application would embed one (or more) browser-window(s) (chromiumembedded for example). You would need bidirectional communication between your web-UI and your domain model/services. I think this allows quick prototyping the UI, a clean separation between logic and UI and potentially easier portability across platforms (compared to WinForms for example). But that is just my view, I was looking for the view of people who have been on that road. An example of an application using a web-ui layer is Light Table. Unfortunately it is not open source (at this point?).

• How to find the list of all available packages along with the lastest version number available in the repositories?

  - by Avinash Raj

  I want to list all the packages(installed or not installed) along with the latest version number available in the repositories. For example: The output of apt-cache policy chromium-browser shows like below $ apt-cache policy chromium-browser chromium-browser: Installed: (none) Candidate: 34.0.1847.116-0ubuntu2 Version table: 34.0.1847.116-0ubuntu2 0 500 http://ftp.cuhk.edu.hk/pub/Linux/ubuntu/ trusty/universe amd64 Packages So the latest version of chromium-browser package available in the repository is 34.0.1847.116-0ubuntu2. Like that, i want to list the version number along with the package names that are available in repositories. And all i want to do this through command-line. I want the output to be like this, chromium-browser 34.0.1847.116-0ubuntu2 xxxxxxxxxxxxxx yyyyyyyyyyy ............ ............

• C# Interview Preparation - References?

  - by Kanini

  This is a specific question relating to C#. However, it can be extrapolated to other languages too. While one is preparing for an interview of a C# Developer (ASP.NET or WinForms or ), what would be the typical reference material that one should look at? Are there any good books/interview question collections that one should look at so that they can be better prepared? This is just to know the different scenarios. For example, I might be writing SQL Stored Procedures and Queries, but I might stumble when asked suddenly Given an Employee Table with the following column(s). EmployeeId, EmployeeName, ManagerId Write a SQL Query which will get me the Name of Employee and Manager Name? NOTE: I am not asking for a Question Bank so that I can learn by rote what the questions are and reproduce them (which, obviously will NOT work!)

• Adopt-a-JSR for Java EE 7 - Getting Started

  - by arungupta

  Adopt-a-JSR is an initiative started by JUG leaders to encourage JUG members to get involved in a JSR, in order to increase grass roots participation. This allows JUG members to provide early feedback to specifications before they are finalized in the JCP. The standards in turn become more complete and developer-friendly after getting feedback from a wide variety of audience. adoptajsr.org provide more details about the logistics and benefits for you and your JUG. A similar activity was conducted for OpenJDK as well. Markus Eisele also provide a great introduction to the program (in German). Java EE 7 (JSR 342) is scheduled to go final in Q2 2013. There are several new JSRs that are getting included in the platform (e.g. WebSocket, JSON, and Batch), a few existing ones are getting an overhaul (e.g. JAX-RS 2 and JMS 2), and several other getting minor updates (e.g. JPA 2.1 and Servlets 3.1). Each Java EE 7 JSR can leverage your expertise and would love your JUG to adopt a JSR. What does it mean to adopt a JSR ? Your JUG is going to identify a particular JSR, or multiple JSRs, that is of interest to the JUG members. This is mostly done by polling/discussing on your local JUG members list. Your JUG will download and review the specification(s) and javadocs for clarity and completeness. The complete set of Java EE 7 specifications, their download links, and EG archives are listed here. glassfish.org/adoptajsr provide specific areas where different specification leads are looking for feedback. Your JUG can then think of a sample application that can be built using the chosen specification(s). An existing use case (from work or a personal hobby project) may be chosen to be implemented instead. This is where your creativity and uniqueness comes into play. Most of the implementations are already integrated in GlassFish 4 and others will be integrated soon. You can also explore integration of multiple technologies and provide feedback on the simplicity and ease-of-use of the programming model. Especially look for integration with existing Java EE technologies and see if you find any discrepancies. Report any missing features that may be included in future release of the specification. The most important part is to provide feedback by filing bugs on the corresponding spec or RI project. Any thing that is not clear either in the spec or implementation should be filed as a bug. This is what will ensure that specification and implementation leads are getting the required feedback and improving the quality of the final deliverable of the JSR. How do I get started ? A simple way to get started can be achieved by following S.M.A.R.T. as explained below. Specific Identify who all will be involved ? What would you like to accomplish ? For example, even though building a sample app will provide real-world validity of the API but because of time constraints you may identify that reviewing the specification and javadocs only can be accomplished. Establish a time frame by which the activities need to be complete. Measurable Define a success for metrics. For example, this could be the number of bugs filed. Remember, quality of bugs is more important that quantity of bugs. Define your end goal, for example, reviewing 4 chapters of the specification or completing the sample application. Create a dashboard that will highlight your JUG's contribution to this effort. Attainable Make sure JUG members understand the time commitment required for providing feedback. This can vary based upon the level of involvement (any is good!) and the number of specifications picked. adoptajsr.org defines different categories of involvement. Once again, any level of involvement is good. Just reviewing a chapter, a section, or javadocs for your usecase is helpful. Relevant Pick JSRs that JUG members are willing and able to work. If the JUG members are not interested then they might loose motivation half-way through. The "able" part is tricky as you can always stretch yourself and learn a new skill ;-) Time-bound Define a time table of activities with clearly defined tasks. A tentative time table may look like: Dec 25: Discuss and agree upon the specifications with JUG Jan 1: Start Adopt-a-JSR for Java EE 7 Jan 15: Initial spec reading complete. Keep thinking through the application that will be implemented. Jan 22: Early design of the sample application is ready Jan 29: JUG members agree upon the application Next 4 weeks: Implement the application Of course, you'll need to alter this based upon your commitment. Maintaining an activity dashboard will help you monitor and track the progress. Make sure to keep filing bugs through out the process! 12 JUGs from around the world (SouJava, Campinas JUG, Chennai JUG, London Java Community, BeJUG, Morocco JUG, Peru JUG, Indonesia JUG, Congo JUG, Silicon Valley JUG, Madrid JUG, and Houston JUG) have already adopted one of the Java EE 7 JSRs. I'm already helping some JUGs bootstrap and would love to help your JUG too. What are you waiting for ?

• Defining Your Online Segmentation and Targeting Strategy

Often, I’ve heard web managers say that their segments aren’t well understood yet, so they can’t really deliver personalized online experiences that are meaningful. This lack of complete understanding means that they don't really bother to try. But, I don’t think you necessarily need to have an elaborate segmentation and targeting strategy already in place to start delivering a more relevant online customer experience. Sometimes it helps to think of how segmentation and targeting might solve some of the challenges your sites visitors are currently experiencing on your web presence, rather than doing nothing and waiting until a fully baked segmentation strategy lands in your inbox.  For example, perhaps you have a broad and varied service offering that makes it difficult for site visitors to easily find the solutions that are most relevant for them.  How can segmentation and targeting help solve this problem?  Or maybe it’s like the airline I described in Monday’s post where the special deals featured on the home page are only relevant to site visitors from a couple of cities.  Couldn’t segmentation and targeting help them to highlight offers on their home page that are relevant to a larger share of their site visitors? Your early segmentation and targeting efforts do not need to be complicated.  There are simple ways to start delivering a more relevant online customer experience, even if you’re dealing with anonymous site visitors.  These include targeting content to site visitors based on: Referral: Deliver targeted content to your site visitors that is based on where they came from or the search term they used to find your site Behavior:  Deliver content to your site visitors that is related or similar to content they’ve clicked on already Location:  Deliver content your site visitors that is most relevant for their geographic location (this would solve that pesky airline home page problem described above) So as you can see, there really are some very simple ways in which you can start improving your online customer experience using very basic segmentation and targeting methods.  One thing to keep in mind as you start to define you segmentation and targeting strategy is that there are many different types of attributes or combinations of attributes upon which you can base your segmentation and targeting strategy.  In addition to referral, behavior and location, other attributes that you should consider are: Profile Information:  What profile information do you know about this customer already?  Perhaps they provided some information on their interests and preferences when they first registered with your site. Time:  What time is it and how does that impact what my site visitors are looking for or trying to do? Demographics: What are my site visitors’ ages, incomes or ethnicities? Which attributes you select to include in your segmentation strategy will depend on your unique business needs and objectives.  Attributes such as behavior or referral may not be the most important targeting criteria depending on your situation. For example, if you’re a newspaper you might know that certain visitors are sports fans based on their profile information.  You can create a segment for sports fans and target sports related content to that segment of your readership online.  Or perhaps, a reader is browsing stories that are related to politics; you can use that visitor’s behavior to assign him or her to a segment for those interested in politics. From there you can recommend more stories to that visitor based on their interest in politics. For an airline, the visitor’s location may be a more important attribute. By detecting the visitor’s location, you can assign them to an appropriate segment and then target special flights and offers to them based on their likely departure airport. As you can see, there are many practical ways that you can start improving the experience your customers receive on your web presence using fairly basic segmentation and targeting techniques.

• New install preserving home directory

  - by john francis lee

  I have 32bit 11.10 installed on an LVM disk taking up all 500gb, and I would like to install 64bit 12.04 on top ... preserving the data in my home directory. I used to do that pre-LVM by just not formatting the partition mounted as /home, installing over / and /usr and formatting /tmp ... but now I don't recognize the partition table. I've never had much luck with 'upograde' and so I just install afresh when I want t new version. Surely I can do what I want, can't I?

• InnoDB Compression Improvements in MySQL 5.6

  - by Inaam Rana

  MySQL 5.6 comes with significant improvements for the compression support inside InnoDB. The enhancements that we'll talk about in this piece are also a good example of community contributions. The work on these was conceived, implemented and contributed by the engineers at Facebook. Before we plunge into the details let us familiarize ourselves with some of the key concepts surrounding InnoDB compression. In InnoDB compressed pages are fixed size. Supported sizes are 1, 2, 4, 8 and 16K. The compressed page size is specified at table creation time. InnoDB uses zlib for compression. InnoDB buffer pool will attempt to cache compressed pages like normal pages. However, whenever a page is actively used by a transaction, we'll always have the uncompressed version of the page as well i.e.: we can have a page in the buffer pool in compressed only form or in a state where we have both the compressed page and uncompressed version but we'll never have a page in uncompressed only form. On-disk we'll always only have the compressed page. When both compressed and uncompressed images are present in the buffer pool they are always kept in sync i.e.: changes are applied to both atomically. Recompression happens when changes are made to the compressed data. In order to minimize recompressions InnoDB maintains a modification log within a compressed page. This is the extra space available in the page after compression and it is used to log modifications to the compressed data thus avoiding recompressions. DELETE (and ROLLBACK of DELETE) and purge can be performed without recompressing the page. This is because the delete-mark bit and the system fields DB_TRX_ID and DB_ROLL_PTR are stored in uncompressed format on the compressed page. A record can be purged by shuffling entries in the compressed page directory. This can also be useful for updates of indexed columns, because UPDATE of a key is mapped to INSERT+DELETE+purge. A compression failure happens when we attempt to recompress a page and it does not fit in the fixed size. In such case, we first try to reorganize the page and attempt to recompress and if that fails as well then we split the page into two and recompress both pages. Now lets talk about the three major improvements that we made in MySQL 5.6.Logging of Compressed Page Images:InnoDB used to log entire compressed data on the page to the redo logs when recompression happens. This was an extra safety measure to guard against the rare case where an attempt is made to do recovery using a different zlib version from the one that was used before the crash. Because recovery is a page level operation in InnoDB we have to be sure that all recompress attempts must succeed without causing a btree page split. However, writing entire compressed data images to the redo log files not only makes the operation heavy duty but can also adversely affect flushing activity. This happens because redo space is used in a circular fashion and when we generate much more than normal redo we fill up the space much more quickly and in order to reuse the redo space we have to flush the corresponding dirty pages from the buffer pool.Starting with MySQL 5.6 a new global configuration parameter innodb_log_compressed_pages. The default value is true which is same as the current behavior. If you are sure that you are not going to attempt to recover from a crash using a different version of zlib then you should set this parameter to false. This is a dynamic parameter.Compression Level:You can now set the compression level that zlib should choose to compress the data. The global parameter is innodb_compression_level - the default value is 6 (the zlib default) and allowed values are 1 to 9. Again the parameter is dynamic i.e.: you can change it on the fly.Dynamic Padding to Reduce Compression Failures:Compression failures are expensive in terms of CPU. We go through the hoops of recompress, failure, reorganize, recompress, failure and finally page split. At the same time, how often we encounter compression failure depends largely on the compressibility of the data. In MySQL 5.6, courtesy of Facebook engineers, we have an adaptive algorithm based on per-index statistics that we gather about compression operations. The idea is that if a certain index/table is experiencing too many compression failures then we should try to pack the 16K uncompressed version of the page less densely i.e.: we let some space in the 16K page go unused in an attempt that the recompression won't end up in a failure. In other words, we dynamically keep adding 'pad' to the 16K page till we get compression failures within an agreeable range. It works the other way as well, that is we'll keep removing the pad if failure rate is fairly low. To tune the padding effort two configuration variables are exposed. innodb_compression_failure_threshold_pct: default 5, range 0 - 100,dynamic, implies the percentage of compress ops to fail before we start using to padding. Value 0 has a special meaning of disabling the padding. innodb_compression_pad_pct_max: default 50, range 0 - 75, dynamic, the  maximum percentage of uncompressed data page that can be reserved as pad.

• Writing use cases for XML mapping scenarios between two different systems

  - by deepak_prn

  I am having some trouble writing use cases for XML mapping after a certain trigger invoked by the system. For example, one of the scenarios goes: the store cashier sells an item, the transaction data is sent to Data management system. Now, I am writing a functional design for the scenario which deals with mapping XML fields between our system and the data management system. Question : I was wondering if some one had to deal with writing use cases or extension use cases for mapping XML fields between two systems? (There is no XSLT involved) and if you used a table to represent the fields mapping (example is below) or any other visualization tool which does not break the bank ? I searched many questions on SO and here but nothing came close to my requirement.

• embedding LEFT OUTER JOIN within INNER JOIN

  - by user3424954

  I am having some problems with one of the question's answered in the book "SQL FOR MERE MORTALS". Here is the problem statement Here is the Database Structure Here is the answer which I am unable to comprehend Here is an answer which looks perfect to me Now the problem with the first answer I am having is: We first use LEFT OUTER JOIN for recipe class and recipes. So it selects all recipe class rows but only matching recipes. Perfecty fine as the question is demanding. Lets call this result set R. Now in the next step when we use INNER JOIN to join RecipieIngridients, it should filter out the rows from R in which Recipie ID doesn't match with the Recipe Id in Recipie Ingredients and hence filtering out the related Recipe class and recipe description also(Since it filters out the entire row of R). So this contradicts with the problem which demands all recipieID and RecipieDescription to be displayed from Recipe_Classes Table in this very step only. How can it be correct. Or Am i Missing some concept.

• SPARC T4-4 Delivers World Record Performance on Oracle OLAP Perf Version 2 Benchmark

  - by Brian

  Oracle's SPARC T4-4 server delivered world record performance with subsecond response time on the Oracle OLAP Perf Version 2 benchmark using Oracle Database 11g Release 2 running on Oracle Solaris 11. The SPARC T4-4 server achieved throughput of 430,000 cube-queries/hour with an average response time of 0.85 seconds and the median response time of 0.43 seconds. This was achieved by using only 60% of the available CPU resources leaving plenty of headroom for future growth. The SPARC T4-4 server operated on an Oracle OLAP cube with a 4 billion row fact table of sales data containing 4 dimensions. This represents as many as 90 quintillion aggregate rows (90 followed by 18 zeros). Performance Landscape Oracle OLAP Perf Version 2 Benchmark 4 Billion Fact Table Rows System Queries/hour Users* Response Time (sec) Average Median SPARC T4-4 430,000 7,300 0.85 0.43 * Users - the supported number of users with a given think time of 60 seconds Configuration Summary and Results Hardware Configuration: SPARC T4-4 server with 4 x SPARC T4 processors, 3.0 GHz 1 TB memory Data Storage 1 x Sun Fire X4275 (using COMSTAR) 2 x Sun Storage F5100 Flash Array (each with 80 FMODs) Redo Storage 1 x Sun Fire X4275 (using COMSTAR with 8 HDD) Software Configuration: Oracle Solaris 11 11/11 Oracle Database 11g Release 2 (11.2.0.3) with Oracle OLAP option Benchmark Description The Oracle OLAP Perf Version 2 benchmark is a workload designed to demonstrate and stress the Oracle OLAP product's core features of fast query, fast update, and rich calculations on a multi-dimensional model to support enhanced Data Warehousing. The bulk of the benchmark entails running a number of concurrent users, each issuing typical multidimensional queries against an Oracle OLAP cube consisting of a number of years of sales data with fully pre-computed aggregations. The cube has four dimensions: time, product, customer, and channel. Each query user issues approximately 150 different queries. One query chain may ask for total sales in a particular region (e.g South America) for a particular time period (e.g. Q4 of 2010) followed by additional queries which drill down into sales for individual countries (e.g. Chile, Peru, etc.) with further queries drilling down into individual stores, etc. Another query chain may ask for yearly comparisons of total sales for some product category (e.g. major household appliances) and then issue further queries drilling down into particular products (e.g. refrigerators, stoves. etc.), particular regions, particular customers, etc. Results from version 2 of the benchmark are not comparable with version 1. The primary difference is the type of queries along with the query mix. Key Points and Best Practices Since typical BI users are often likely to issue similar queries, with different constants in the where clauses, setting the init.ora prameter "cursor_sharing" to "force" will provide for additional query throughput and a larger number of potential users. Except for this setting, together with making full use of available memory, out of the box performance for the OLAP Perf workload should provide results similar to what is reported here. For a given number of query users with zero think time, the main measured metrics are the average query response time, the median query response time, and the query throughput. A derived metric is the maximum number of users the system can support achieving the measured response time assuming some non-zero think time. The calculation of the maximum number of users follows from the well-known response-time law N = (rt + tt) * tp where rt is the average response time, tt is the think time and tp is the measured throughput. Setting tt to 60 seconds, rt to 0.85 seconds and tp to 119.44 queries/sec (430,000 queries/hour), the above formula shows that the T4-4 server will support 7,300 concurrent users with a think time of 60 seconds and an average response time of 0.85 seconds.

• What is the best approach to copy public dynamic pages?

  - by Renan

  Situation: the government is supposed to publish official information online such as acts and laws. Problem: they're using 90s expertise to do it. You can tell that by the constant use of deprecated html tags such as <table and the lack of any compression at all, which makes some documents go way over 700,000 bytes even though they're pure text. Side problem: some companies are actually editing and selling this content that should be public and free. What I need to know is the best approach to offer said official content in my own site for free. I've thought of setting up a mirror to copy the official pages from time to time, since some of them are updated frequently, which would automatically be compressed as all my pages are via htaccess.

• User defined type for healthcare / Medical Records variable name prefixes?

  - by Peter Turner

  I was reading Code Complete regarding variable naming in trying to find an answer to this question and stumbled on a table of commonly accepted prefixes for programming word processor software. Well, I'm not a word processor software programmer, but if I was, I'd be happy to use those user defined types. Since I'm a programmer for a smallish healthcare ISV, and have no contact with the larger community of healthcare software programmers (other than the neglected and forsaken HealthCareIT.SE where I never had the chance to ask this question). I want to know if there is a coding convention for medical records. Like Patient = pnt and Chart = chrt and Medication = med or mdctn or whatever. I'm not talking full on hungarian notation, but just a standard that would fit in code complete in place of that wonderful chart of word processor UDT's which are of so little use to me.

• How do I do JavaScript Array Animation

  - by Henry

  I'm making a game but don't know how to do Array Animation with the png Array and game Surface that I made below. I'm trying to make it so that when the Right arrow key is pressed, the character animates as if it is walking to the right and when the Left arrow key is pressed it animates as if it is walking to the left (kind of like Mario). I put everything on a surface instead of the canvas. Everything is explained in the code below. I couldn't find help on this anywhere. I hope what I got below makes sense. I'm basically a beginner with JavaScript. I'll be back if more is needed: <!doctype html5> <html> <head></head> <script src="graphics.js"></script> <script src="object.js"></script> <body onkeydown ="keyDown(event)" onkeyup ="keyUp(event)" ></body> <script> //"Surface" is where I want to display my animation. It's like the HTML // canvas but it's not that. It's just the surface to where everything in the //game and the game itself will be displayed. var Surface = new Graphics(600, 400, "skyblue"); //here's the array that I want to use for animation var player = new Array("StandsRight.png", "WalksRight.png", "StandsLeft.png","WalksLeft.png" ); //Here is the X coordinate, Y coordinate, the beginning png for the animation, //and the object's name "player." I also turned the array into an object (but //I don't know if I was supposed to do that or not). var player = new Object(50, 100, 40, 115, "StandsRight.png","player"); //When doing animation I know that it requires a "loop", but I don't // know how to connect it so that it works with the arrays so that //it could animate. var loop = 0; //this actually puts "player" on screen. It makes player visible and //it is where I would like the animation to occur. Surface.drawObject(player); //this would be the key that makes "player" animation in the righward direction function keyDown(e) { if (e.keyCode == 39); } //this would be the key that makes "player" animation in the leftward direction function keyUp(e){ if (e.keyCode == 39); } //this is the Mainloop where the game will function MainLoop(); //the mainloop functionized function MainLoop(){ //this is how fast or slow I could want the entire game to go setTimeout(MainLoop, 10); } </script> </html> From here, are the "graphic.js" and the "object.js" files below. In this section is the graphics.js file. This graphics.js part below is linked to the: script src="graphics.js" html script section that I wrote above. Basically, below is a seperate file that I used for Graphics, and to run the code above, make this graphics.js code that I post below here, a separate filed called: graphics.js function Graphics(w,h,c) { document.body.innerHTML += "<table style='position:absolute;font- size:0;top:0;left:0;border-spacing:0;border- width:0;width:"+w+";height:"+h+";background-color:"+c+";' border=1><tr><td> </table>\n"; this.drawRectangle = function(x,y,w,h,c,n) { document.body.innerHTML += "<div style='position:absolute;font-size:0;left:" + x + ";top:" + y + ";width:" + w + ";height:" + h + ";background-color:" + c + ";' id='" + n + "'></div>\n"; } this.drawTexture = function(x,y,w,h,t,n) { document.body.innerHTML += "<img style='position:absolute;font-size:0;left:" + x + ";top:" + y + ";width:" + w + ";height:" + h + ";' id='" + n + "' src='" + t + "'> </img>\n"; } this.drawObject = function(o) { document.body.innerHTML += "<img style='position:absolute;font-size:0;left:" + o.X + ";top:" + o.Y + ";width:" + o.Width + ";height:" + o.Height + ";' id='" + o.Name + "' src='" + o.Sprite + "'></img>\n"; } this.moveGraphic = function(x,y,n) { document.getElementById(n).style.left = x; document.getElementById(n).style.top = y; } this.removeGraphic = function(n){ document.getElementById(n).parentNode.removeChild(document.getElementById(n)); } } Finally, is the object.js file linked to the script src="object.js"" in the html game file above the graphics.js part I just wrote. Basically, this is a separate file too, so thus, in order to run or test the html game code in the very first section I wrote, a person has to also make this code below a separate file called: object.js I hope this helps: function Object(x,y,w,h,t,n) { this.X = x; this.Y = y; this.Velocity_X = 0; this.Velocity_Y = 0; this.Previous_X = 0; this.Previous_Y = 0; this.Width = w; this.Height = h; this.Sprite = t; this.Name = n; this.Exists = true; } In all, this game is made based on a tutorial on youtube at: http://www.youtube.com/watch?v=t2kUzgFM4lY&feature=relmfu I'm just trying to learn how to add animations with it now. I hope the above helps. If not, let me know. Thanks

• Creating the Business Card Request InfoPath Form

  - by JKenderdine

  Business Card Request Demo Files Back in January I spoke at SharePoint Saturday Virginia Beach about InfoPath forms and Web Part deployment.  Below is some of the information and details regarding the form I created for the session.  There are many blogs and Microsoft articles on how to create a basic form so I won’t repeat that information here.   This blog will just explain a few of the options I chose when creating the solutions for SPS Virginia Beach.  The above link contains the zipped package files of the two InfoPath forms(no code solution and coded solution), the list template for the Location list I used, and the PowerPoint deck.  If you plan to use these templates, you will need to update the forms to work within your own environments (change data connections, code links, etc.).  Also, you must have the SharePoint Enterprise version, with InfoPath Services configured in order to use the Web Browser enabled forms. So what are the requirements for this template? Business Card Request Form Template Design Plan: Gather user information and requirements for card Pull in as much user information as possible. Use data from the user profile web services as a data source Show and hide fields as necessary for requirements Create multiple views – one for those submitting the form and Another view for the executive assistants placing the orders. Browser based form integrated into SharePoint team site Submitted directly to form library The base form was created using the blank template.  The table and rows were added using Insert tab and selecting Custom Table.  The use of tables is a great way to make sure everything lines up.  You do have to split the tables from time to time.  If you’ve ever split cells and then tried to re-align one to find that you impacted the others, you know why.  Here is what the base form looks like in InfoPath.   Show and hide fields as necessary for requirements You will notice I also used Sections within the form.  These show or hide depending on options selected or whether or not fields are blank.  This is a great way to prevent your users from feeling overwhelmed with a large form (this one wouldn’t apply).  Although not used in this one, you can also use various views with a tab interface.  I’ll show that in another post. Gather user information and requirements for card Pull in as much user information as possible. Use data from the user profile web services as a data source Utilizing rules you can load data when the form initiates (Data tab, Form Load).  Anything you can automate is always appreciated by the user as that is data they don’t have to enter.  For example, loading their user id or other user information on load: Always keep in mind though how much data you load and the method for loading that data (through rules, code, etc.).  They have an impact on form performance.  The form will take longer to load if you bring in a ton of data from external sources.  Laura Rogers has a great blog post on using the User Information List to load user information.   If the user has logged into SharePoint, then this can be used quite effectively and without a huge performance hit.   What I have found is that using the User Profile service via code behind or the Web Service “GetUserProfileByName” (as above) can take more time to load the user data.  Just food for thought. You must add the data connection in order for the above rules to work.  You can connect to the data connection through the Data tab, Data Connections or select Manage Data Connections link which appears under the main data source.  The data connections can be SharePoint lists or libraries, SQL data tables, XML files, etc.  Create multiple views – one for those submitting the form and Another view for the executive assistants placing the orders. You can also create multiple views for the users to enhance their experience.  Once they’ve entered the information and submitted their request for business cards, they don’t really need to see the main data input screen any more.  They just need to view what they entered. From the Page Design tab, select New View and give the view a name.  To review the existing views, click the down arrow under View: The ReviewView shows just what the user needs and nothing more: Once you have everything configured, the form should be tested within a Test SharePoint environment before final deployment to production.  This validates you don’t have any rules or code that could impact the server negatively. Submitted directly to form library   You will need to know the form library that you will be submitting to when publishing the template.  Configure the Submit data connection to connect to this library.  There is already one configured in the sample,  but it will need to be updated to your environment prior to publishing. The Design template is different from the Published template.  While both have the .XSN extension, the published template contains all the “package” information for the form.  The published form is what is loaded into Central Admin, not the design template. Browser based form integrated into SharePoint team site In Central Admin, under General Settings, select Manage Form Templates.  Upload the published form template and Activate it to a site collection. Now it is available as a content type to select in the form library.  Some documentation on publishing form templates:  Technet – Manage administrator approved form templates And that’s all our base requirements.  Hope this helps to give a good start.

• SANS Webcast: Label Based Access Controls in Oracle Database 11g

  - by Troy Kitch

  Controlling access to data subsets within an application table can be difficult and inefficient especially when faced with specific data ownership, consolidation and multi-tenancy requirements. However, this can be elegantly addressed using label based access control (LBAC). In this webcast you will learn how LBAC using Oracle Label Security and Oracle Database 11g can easily enforce row-level access based on user security clearance. In addition, Oracle security experts will discuss real world case studies demonstrating how customers, in industries ranging from retail to government, are relying on Oracle Label Security for virtual information partitioning and secure consolidation of information.  Register for the July 12 webcast now.
