  • UDK game Prisoners/Guards

    - by RR_1990
    For school I need to make a little game with UDK, the concept of the game is: The player is the headguard, he will have some other guard (bots) who will follow him. Between the other guards and the player are some prisoners who need to evade the other guards. It needs to look like this My idea was to let the guard bots follow the player at a certain distance and let the prisoners bots in the middle try to evade the guard bots. Now is the problem i'm new to Unreal Script and the school doesn't support me that well. Untill now I have only was able to make the guard bots follow me. I hope you guys can help me or make me something that will make this game work. Here is the class i'm using to let te bots follow me: class ChaseControllerAI extends AIController; var Pawn player; var float minimalDistance; var float speed; var float distanceToPlayer; var vector selfToPlayer; auto state Idle { function BeginState(Name PreviousStateName) { Super.BeginState(PreviousStateName); } event SeePlayer(Pawn p) { player = p; GotoState('Chase'); } Begin: player = none; self.Pawn.Velocity.x = 0.0; self.Pawn.Velocity.Y = 0.0; self.Pawn.Velocity.Z = 0.0; } state Chase { function BeginState(Name PreviousStateName) { Super.BeginState(PreviousStateName); } event PlayerOutOfReach() { `Log("ChaseControllerAI CHASE Player out of reach."); GotoState('Idle'); } // class ChaseController extends AIController; CONTINUED // State Chase (continued) event Tick(float deltaTime) { `Log("ChaseControllerAI in Event Tick."); selfToPlayer = self.player.Location - self.Pawn.Location; distanceToPlayer = Abs(VSize(selfToPlayer)); if (distanceToPlayer > minimalDistance) { PlayerOutOfReach(); } else { self.Pawn.Velocity = Normal(selfToPlayer) * speed; //self.Pawn.Acceleration = Normal(selfToPlayer) * speed; self.Pawn.SetRotation(rotator(selfToPlayer)); self.Pawn.Move(self.Pawn.Velocity*0.001); // or *deltaTime } } Begin: `Log("Current state Chase:Begin: " @GetStateName()@""); } defaultproperties { bAdjustFromWalls=true; bIsPlayer= true; minimalDistance = 1024; //org 1024 speed = 500; }

  • A Slice of Raspberry Pi

    - by Phil Factor
    Guest editorial for the ITPro/SysAdmin newsletter The Raspberry Pi Foundation has done a superb design job on their new $35 network-enabled Linux computer. This tiny machine, incorporating an ARM processor on a Broadcom BCM2835 multimedia chip, aims to put the fun back into learning computing. The public response has been overwhelmingly positive.Note that aim: "…to put the fun back". Education in Information Technology is in dire straits. It always has been, but seems to have deteriorated further still, even in the face of improved provision of equipment.In many countries, the government controls the curriculum. It predicted a shortage in office-based IT skills, and so geared the ICT curriculum toward mind-numbing training in word-processing and spreadsheet skills. Instead, the shortage has turned out to be in people with an engineering-mindset, who can solve problems with whatever technologies are available and learn new techniques quickly, in a rapidly-changing field.In retrospect, the assumption that specific training was required rather than an education was an idiotic response to the arrival of mainstream information technology. As a result, ICT became a disaster area, which discouraged a generation of youngsters from a career in IT, and thereby led directly to the shortage of people with the skills that are required to exploit the potential of Information Technology..Raspberry Pi aims to reverse the trend. This is a rig that is geared to fast graphics in high resolution. It is no toy. It should be a superb games machine. However, the use of Fedora, Debian, or Arch Linux ARM shows the more serious educational intent behind the Foundation's work. It looks like it will even do some office work too!So, get hold of any power supply that provides a 5VDC source at the required 700mA; an old Blackberry charger will do or, alternatively, it will run off four AA cells. You'll need a USB hub to support the mouse and keyboard, and maybe a hard drive. You'll want a DVI monitor (with audio out) or TV (sound and video). You'll also need to be able to cope with wired Ethernet 10/100, if you want networking.With this lot assembled, stick the paraphernalia on the back of the HDTV with Blu Tack, get a nice keyboard, and you have a classy Linux-based home computer. The major cost is in the T.V and the keyboard. If you're not already writing software for this platform, then maybe, at a time when some countries are talking of orders in the millions, you should consider it.

  • Suggestions for connecting .NET WPF GUI with Java SE Server

    - by Sam Goldberg
    BACKGROUND We are building a Java (SE) trading application which will be monitoring market data and sending trade messages based on the market data, and also on user defined configuration parameters. We are planning to provide the user with a thin client, built in .NET (WPF) for managing the parameters, controlling the server behavior, and viewing the current state of the trading. The client doesn't need real-time updates; it will instead update the view once every few seconds (or whatever interval is configured by the user). The client has about 6 different operations it needs to perform with the server, for example: CRUD with configuration parameters query subset of the data receive updates of current positions from server It is possible that most of the different operations (except for receiving data) are just different flavors of managing the configuration parameters, but it's too early in our analysis for us to be sure. To connect the client with the server, we have been considering using: SOAP Web Service RESTful service building a custom TCP/IP based API (text or xml) (least preferred - but we use this approach with other applications we have) As best as I understand, pros and cons of the different web service flavors are: SOAP pro: totally automated in .NET (and Java), modifying server side interface require no code changes in communication layer, just running refresh on Web Service reference to regenerate the classes. con: more overhead in the communication layer sending more text, etc. We're not using J2EE container so maybe doesn't work so well with J2SE REST pro: lighter weight, less data. Has good .NET and Java support. (I don't have any real experience with this, so don't know what other benefits it has.) con: client will not be automatically aware if there are any new operations or properties added (?), so communication layer needs to be updated by developer if server interface changes. con: (both approaches) Server cannot really push updates to the client at regular intervals (?) (However, we won't mind if client polls the server to get updates.) QUESTION What are your opinions on the above options or suggestions for other ways to connect the 2 parts? (Ideally, we don't want to put much work into the communication layer, because it's not the significant part of the application so the more off-the-shelf and automated the better.)

  • Framework 4 Features: User Propogation to the Database

    - by Anthony Shorten
    Once of the features I mentioned in a previous entry was the ability for Oracle Utilities Application Framework V4 to automatically propogate the end user to the database connection. This bears more explanation. In the past releases of the Oracle Utilities Application Framework, all database connections are pooled and shared within a channel of access. So for example, the online connections on the Business Application Server share a common pool of connections and the batch in a thread pool shares a seperate pool of connections. The connections are pooled for performance reasons (the most expensive part of a typical transaction is opening and closing connections so we save time by having them ready beforehand). The idea is that when a business function needs some SQL to be execute it takes a spare connection from the pool, executes the SQL and then returns the connection back to the pool for reuse. Unfortunelty to support the pool being started and ready before the transactions arrives means that you need to have a shared userid (as you dont know the users who need them beforehand). Therefore each connection uses the same database user to execute the SQL it needs. This is acceptable for executing transactions, generally but does not allow the DBA or other tools to ascertain which end user is actually running the transaction. In Oracle Utilities Application Framework V4, we now set the CLIENT_IDENTIFIER to the end userid (not the Login Id) when the connection is taken from the pool and used and reset it back to blank when returned to the pool. The CLIENT_IDENTIFIER is a feature that is present in the Oracle Database connection information. From a monitoring perspective, when a connection to the database is actively running SQL, the end user is now able to be determined by querying the CLIENT_IDENTIFIER on the session object within the database. This can be done in the DBA's favorite monitoring tool (even just some SQL on the v$session table is enough). This has other implications as well. Oracle sells a lot of other security addons to the database and so do third parties. If a site wants to have additional levels of security or auditing in the database then the CLIENT_IDENTIFIER, if supported, is now available to be recorded or used by those products to provide additional levels of security. This facility was one of the highly "nice to haves" that customers would ask us about so we now allow it to be used to allow finer grained monitoring and additional security facilities. Note: This facility is only available for customers using the Oracle Database versions of our products.

  • How does I/O work for large graph databases?

    - by tjb1982
    I should preface this by saying that I'm mostly a front end web developer, trained as a musician, but over the past few years I've been getting more and more into computer science. So one idea I have as a fun toy project to learn about data structures and C programming was to design and implement my own very simple database that would manage an adjacency list of posts. I don't want SQL (maybe I'll do my own query language? I'm just having fun). It should support ACID. It should be capable of storing 1TB let's say. So with that, I was trying to think of how a database even stores data, without regard to data structures necessarily. I'm working on linux, and I've read that in that world "everything is a file," including hardware (like /dev/*), so I think that that obviously has to apply to a database, too, and it clearly does--whether it's MySQL or PostgreSQL or Neo4j, the database itself is a collection of files you can see in the filesystem. That said, there would come a point in scale where loading the entire database into primary memory just wouldn't work, so it doesn't make sense to design it with that mindset (I assume). However, reading from secondary memory would be much slower and regardless some portion of the database has to be in primary memory in order for you to be able to do anything with it. I read this post: Why use a database instead of just saving your data to disk? And I found it difficult to understand how other databases, like SQLite or Neo4j, read and write from secondary memory and are still very fast (faster, it would seem, than simply writing files to the filesystem as the above question suggests). It seems the key is indexing. But even indexes need to be stored in secondary memory. They are inherently smaller than the database itself, but indexes in a very large database might be prohibitively large, too. So my question is how is I/O generally done with large databases like the one I described above that would be at least 1TB storing a big adjacency list? If indexing is more or less the answer, how exactly does indexing work--what data structures should be involved?

  • Should I be looking for an alternative to Zen Cart as my business grows?

    - by MarkS
    I created a business website for a family business which is growing. It's my family, and I'm a software developer, but I don't want to rebuild the wheels or be a shopping cart programmer. For this business, I need the web store to "just work", but... it gets complicated... There are two parts of this business website. One of them is driven by Wordpress and I use the awesome Thesis theme. This is modern, flexible, and saves me a lot of time from doing custom coding and styling. I couldn't be more pleased with this arrangement. The other part of the site is a Zen Cart store. It's administration and it's flexibility is frustrating and archaic Web 1.0. For the past few years, I keep hearing that the developers are working on a 2.0 version of Zen Cart, but they haven't communicated anything significant in the past few years other than to say, "When it's ready, we'll let you know." What I'm looking for in a cart, I would need to install 6-10 additional mods, and would need to do a lot of custom coding. I'm now willing to pay for a top-notch e-commerce solution for a small business that we can grow up into a larger business over time. Requirements: Extremely flexible shipping that let's us set up rules per product/category, tables of rates, calculated rates, max package weighs, etc. (flexibility like that available with CEON Advance Shipping Module for Zen Cart Coupons and gift certificates Manual order entry for phone orders Multi-channel support (We also sell on Amazon, eBay, use Google Base and we want to maintain one set of inventory and have it kept current) Decent SEO features Reviews and star-ratings on products Easy social networking features for sharing, following, liking, etc) Easy integration with AdWords and analytics tracking Modern and very usable product and store administration (Like I was saying, I'm spoiled by Wordpress and Thesis) At the end of the day, I don't care if it's a hosted solution or if I have to host it myself. I just want something that is going to stay up-to-date, regularly be maintained and improved, and if I have to update it, things like the one-click update present in Wordpress is something it has to have. Professional Webmasters, if you had to run a store / website, but you had to spend your time focusing on your sales and marketing efforts rather than diffing php files and copying and tweaking them to change even the slightest details of your site, what would you choose?

  • Running Teamsite User Admin tool IWUSERADM.exe from ASP.NET

    - by Narendra Tiwari
    It has really been a head scratching task for me. I 've tried many options but nothing worked. Finally I found a workaround on google to achive this by TaskScheduler. PROBLEM When we run Teamsite user administration command line tool IWUSERADM.exe though ASP.Net it gives following error: Application popup: cmd.exe - Application Error : The application failed to initialize properly (0xc0000142). Click on OK to terminate the application. CAUSE No specific cause, it seems to be a bug, supposed to be resolved with this Microsoft patch http://support.microsoft.com/kb/960266. and there is nothing related to permission issue, y web application is impersonated with an administrator account. off course running a bat file from dmin account is a potential secury threat but for this scenario lets conifned our discussion to run the command line tool. RESOLUTION I have not tried this patch as I have not permitted to run this patch on server. Below are the steps to achive the requirement. 1/ Create a batch file which runs the IWUSERADM.exe.         echo - Add Teamsite User    CD E:\Appli\GN00\iw-home\bin    iwuseradm add-user %1 2/ Temporarily create a schedule task and run  the .bat file by scheduled task by ASP.Net code using TaskScheduler http://www.codeproject.com/KB/cs/tsnewlib.aspx. 3/ Here is the function: private int AddTeamsiteUser(string strBatchFilePath, string strUser) { //Get a ScheduledTasks object for the local computer. ScheduledTasks st = new ScheduledTasks(); // Create a task Task t; try{ t = st.CreateTask("~AddTeamsiteUser"); } catch { throw new Exception("Schedule Task ~AddTeamsiteUser already exist."); }    t.SetAccountInformation(yourLogin, yourPassword); //Set the account under which the task should run.  t.Save();  t.Run(); Thread.Sleep(2000); //for sync issue //Remove the scheduled task st.DeleteTask("~AddTeamsiteUser"); return t.ExitCode;   Below are few resources related to the above scenario:- - Task Scheduler Class Library for .NET  http://www.codeproject.com/KB/cs/tsnewlib.aspx - Run a .BAT file from ASP.NET  http://codebetter.com/blogs/brendan.tompkins/archive/2004/05/13/13484.aspx - TaskScheduler Class  http://msdn.microsoft.com/en-us/library/system.threading.tasks.taskscheduler.aspx - Application Hangs whle running iwuseradm.exe through ASP.Net  http://bytes.com/topic/asp-net/answers/733098-system-diagnostics-process-hangs     t.ApplicationName = strBatchFilePath; t.Parameters = strUser; t.Comment = "Adding user to Teamsite Application"

  • Wordpress Installation (on IIS and SQL Server)

    - by Davide Mauri
    To proceed with the installation of Wordpress on SQL Server and IIS, first of all, you need to do the following steps Create a database on SQL Server that will be used by Wordpress Create login that can access to the just created database and put the user into ddladmin, db_datareader, db_datawriter roles Download and unpack Wordpress 3.3.2 (latest version as of 27 May 2012) zip file into a directory of your choice Download the wp-db-abstraction 1.1.4 (latest version as of 27 May 2012) plugin from wordpress.org website Now that the basic action has been done, you can start to setup and configure your Wordpress installation. Unpack and follow the instructions in the README.TXT file to install the Database Abstraction Layer. Mainly you have to: Upload wp-db-abstraction.php and the wp-db-abstraction directory to wp-content/mu-plugins.  This should be parallel to your regular plugins directory.  If the mu-plugins directory does not exist, you must create it. Put the db.php file from inside the wp-db-abstraction.php directory to wp-content/db.php Now you can create an application pool in IIS like the following one Create a website, using the above Application Pool, that points to the folder where you unpacked Wordpress files. Be sure to give the “Write” permission to the IIS account, as pointed out in this (old, but still quite valid) installation manual: http://wordpress.visitmix.com/development/installing-wordpress-on-sql-server#iis Now you’re ready to go. Point your browser to the configured website and the Wordpress installation screen will be there for you. When you’re requested to enter information to connect to MySQL database, simply skip that page, leaving the default values. If you have installed the Database Abstraction Layer, another database installation screen will appear after the one used by MySQL, and here you can enter the configuration information needed to connect to SQL Server. After having finished the installation steps, you should be able to access and navigate your wordpress site.  A final touch, and it’s done: just add the needed rewrite rules http://wordpress.visitmix.com/development/installing-wordpress-on-sql-server#urlrewrite and that’s it! Well. Not really. Unfortunately the current (as of 27 May 2012) version of the Database Abstraction Layer (1.1.4) has some bugs. Luckily they can be quickly fixed: Backslash Fix http://wordpress.org/support/topic/plugin-wp-db-abstraction-fix-problems-with-backslash-usage Select Top 0 Fix Make the change to the file “.\wp-content\mu-plugins\wp-db-abstraction\translations\sqlsrv\translations.php” suggested by “debettap”   http://sourceforge.net/tracker/?func=detail&aid=3485384&group_id=315685&atid=1328061 And now you have a 100% working Wordpress installation on SQL Server! Since I also wanted to take advantage of SQL Server Full Text Search, I’ve created a very simple wordpress plugin to setup full-text search and to use it as website search engine: http://wpfts.codeplex.com/ Enjoy!

  • Fast Data: Go Big. Go Fast.

    - by J Swaroop
    Cross-posting Dain Hansen's excellent recap of the Big Data/Fast Data announcement during OOW: For those of you who may have missed it, today’s second full day of Oracle OpenWorld 2012 started with a rumpus. Joe Tucci, from EMC outlined the human face of big data with real examples of how big data is transforming our world. And no not the usual tried-and-true weblog examples, but real stories about taxi cab drivers in Singapore using big data to better optimize their routes as well as folks just trying to get a better hair cut. Next we heard from Thomas Kurian who talked at length about the important platform characteristics of Oracle’s Cloud and more specifically Oracle’s expanded Cloud Services portfolio. Especially interesting to our integration customers are the messaging support for Oracle’s Cloud applications. What this means is that now Oracle’s Cloud applications have a lightweight integration fabric that on-premise applications can communicate to it via REST-APIs using Oracle SOA Suite. It’s an important element to our strategy at Oracle that supports this idea that whether your requirements are for private or public, Oracle has a solution in the Cloud for all of your applications and we give you more deployment choice than any vendor. If this wasn’t enough to get the juices flowing, later that morning we heard from Hasan Rizvi who outlined in his Fusion Middleware session the four most important enterprise imperatives: Social, Mobile, Cloud, and a brand new one: Fast Data. Today, Rizvi made an important step in the definition of this term to explain that he believes it’s a convergence of four essential technology elements: Event Processing for event filtering, business rules – with Oracle Event Processing Data Transformation and Loading - with Oracle Data Integrator Real-time replication and integration – with Oracle GoldenGate Analytics and data discovery – with Oracle Business Intelligence Each of these four elements can be considered (and architect-ed) together on a single integrated platform that can help customers integrate any type of data (structured, semi-structured) leveraging new styles of big data technologies (MapReduce, HDFS, Hive, NoSQL) to process more volume and variety of data at a faster velocity with greater results.  Fast data processing (and especially real-time) has always been our credo at Oracle with each one of these products in Fusion Middleware. For example, Oracle GoldenGate continues to be made even faster with the recent 11g R2 Release of Oracle GoldenGate which gives us some even greater optimization to Oracle Database with Integrated Capture, as well as some new heterogeneity capabilities. With Oracle Data Integrator with Big Data Connectors, we’re seeing much improved performance by running MapReduce transformations natively on Hadoop systems. And with Oracle Event Processing we’re seeing some remarkable performance with customers like NTT Docomo. Check out their upcoming session at Oracle OpenWorld on Wednesday to hear more how this customer is using Event processing and Big Data together. If you missed any of these sessions and keynotes, not to worry. There's on-demand versions available on the Oracle OpenWorld website. You can also checkout our upcoming webcast where we will outline some of these new breakthroughs in Data Integration technologies for Big Data, Cloud, and Real-time in more details.

  • Mark Zuckerberg tops the list of 50 Highest Rated CEOs. 3 Indian CEOs feature in the list.

    - by Gopinath
    Mark Zuckerberg, the CEO of Facebook is rated as the best CEO according to a report released by the popular employee reviews website Glassdoor.com. 50,000 employees reviews submitted to Glassdoor in the past 1 year are considered for preparing the rating list and Zukerberg topped the list with 99 percent approval to the question “Do you approve of the way your CEO is leading the company?”. Wow! That’s an amazing support to Zukergerg from his employees though stock market and share holders are not with him. Coincidently Facebook is also rated as the best company to work by Glassdoor in a recent survey. Here is the list of top 10 CEOs Mark Zuckerberg, Facebook; 99.3% Approval Bill McDermott & Jim Hagemann Snabe, SAP; 99% Approval Dominic Barton, McKinsey & Company; 97% Approval Jim Turley, Ernst & Young; 96% Approval John E. Schlifske, Northwestern Mutual; 96% Approval Frank D’Souza, Cognizant Technology Solutions; 96% Approval Joe Tucci, EMC; 96% Approval Paul E. Jacobs, QUALCOMM; 95% Approval Richard K. Davis, U.S. Bank; 95% Approval Pierre Nanterme, Accenture; 95% Approval 3 Indian CEOs in the top 50 list – TCS, Wipro & MindTree The list featured three Indian CEOs and all the three are leading Software IT Services organizations in India and creating thousands of IT jobs.  Natarajan Chandrasekaran – the CEO of TCS is at 25th position, Krishnakumar Natarajan – the CEO of MindTree is at 28th position and  Wipro’s T.K.Kurien is at 44th position. Glad to see Indian CEO joining the global ranks. Tech Heavy Weights Google, Apple, Amazon & Microsoft aren’t in top 10 Another thing to note from this report is that the CEO’s of technology heavy weights Google, Apple, Amazon and Microsoft are not in the top10 list- looks like their employees are not really happy with their bosses. At least not as happy as their peers at Facebook. Google CEO’s Larry Page is at 11th position, Jeff Bezos of Amazon at 16th position and Tim Cook of Apple is at 18th position. Well the Microsoft CEO is not even in the list of top 50!! You can read the complete list of ratings at Glassdoor.com’s blog. Photo Credit: Andrew Feinberg

  • Why lock statements don't scale

    - by Alex.Davies
    We are going to have to stop using lock statements one day. Just like we had to stop using goto statements. The problem is similar, they're pretty easy to follow in small programs, but code with locks isn't composable. That means that small pieces of program that work in isolation can't necessarily be put together and work together. Of course actors scale fine :) Why lock statements don't scale as software gets bigger Deadlocks. You have a program with lots of threads picking up lots of locks. You already know that if two of your threads both try to pick up a lock that the other already has, they will deadlock. Your program will come to a grinding halt, and there will be fire and brimstone. "Easy!" you say, "Just make sure all the threads pick up the locks in the same order." Yes, that works. But you've broken composability. Now, to add a new lock to your code, you have to consider all the other locks already in your code and check that they are taken in the right order. Algorithm buffs will have noticed this approach means it takes quadratic time to write a program. That's bad. Why lock statements don't scale as hardware gets bigger Memory bus contention There's another headache, one that most programmers don't usually need to think about, but is going to bite us in a big way in a few years. Locking needs exclusive use of the entire system's memory bus while taking out the lock. That's not too bad for a single or dual-core system, but already for quad-core systems it's a pretty large overhead. Have a look at this blog about the .NET 4 ThreadPool for some numbers and a weird analogy (see the author's comment). Not too bad yet, but I'm scared my 1000 core machine of the future is going to go slower than my machine today! I don't know the answer to this problem yet. Maybe some kind of per-core work queue system with hierarchical work stealing. Definitely hardware support. But what I do know is that using locks specifically prevents any solution to this. We should be abstracting our code away from the details of locks as soon as possible, so we can swap in whatever solution arrives when it does. NAct uses locks at the moment. But my advice is that you code using actors (which do scale well as software gets bigger). And when there's a better way of implementing actors that'll scale well as hardware gets bigger, only NAct needs to work out how to use it, and your program will go fast on it's own.

  • Remote synchronization

    - by Tomas Mysik
    Hi all, today we would like to show you another improvement we have prepared for NetBeans 7.2. Today, let's talk a little bit about remote synchronization. If you already use our simple (S)FTP client, this enhancement could be useful for you. Simply right click on Source Files and select Synchronize. Please notice that the remote synchronization works better only on the whole project (it means that the Source Files must be selected). The Synchronize action is also available on individual files (more files can be selected at once) but the suggested operation (download, upload etc.) does not work so precisely. Also please notice that the suggested operations are not 100% reliable since the timestamps provided by FTP servers are not exact. Once the remote files (their names and paths only, of course) are fetched, the main dialog appears: As you can see, NetBeans tries to suggest you operations (upload, download etc.) which should be done for each individual file of your project. If you are interested only in some particular changes, you can simply filter the list: Since we have a file conflict, we need to resolve it first. Fortunately this is very easy because we just select the desired file and click the Diff button . The remote version of our file is downloaded and compared with the local version. The resut is displayed in the dialog where you can easily apply and/or refuse the remote changes or even simply type manually to the local version of the selected file: Once we are done with our changes, the operation for the selected file changes to Upload and the file is marked with * (since we made some changes). Please notice that if you now click the Cancel button, in fact no changes are done in our local file. As you can see, if we have one or more files selected, we can change their operation to: no operation (file won't be synchronized) download upload delete (both local and remote file) reset (the operation is resetted to the original one suggested by NetBeans and also all changes done via Diff action are discarded) Now we are ready to synchronize our project. NetBeans will show us the synchronization summary (this dialog can be omitted, see the Show Summary checkbox on the previous image). The synchronization itself starts and we can see its progress and of course its result. As always, all the operations can be reviewed in the Output window. That's all for today, as always, please test it and report all the issues or enhancements you find in NetBeans BugZilla (component php, subcomponent FTP support).

  • Where are my sub templates?

    - by Tim Dexter
    This one is for standalone/BIEE uses of Publisher. All the ERP/CRM/HCM folks are already catered for and can tuck into a nut cutlet and arugala salad. Sorry, I have just watched Food Inc and even if only half of it is true; Im still on a crusade in my house against mass produced food. Wake up World! If you have ventured into the world of sub templating, you'll be reaping some development benefit. In terms of shared report components and calculations they are very useful. Just exporting all of your report headers and footers to a single sub template can potentially save you hours and hours of work and make you look like a star. If someone in management gets it into their head that they would like Comic San Serif font rather than Arial in their report headers, its a 10 min job rather than 100 hours! What about the rest of the report content? I hear you cry. Its coming in 11g, full master template support. Your management wants bright blue borders with yellow backgrounds for all the tables in your reports, 5 minute job! Getting back to sub templates and my comment about all the ERP/CRM/HCM folks be catered for. In the standalone release there is no out of the box directory for you to drop your sub templates. Dropping them into the main report directory would make sense but they are not accessible there via a URL. An oversight on our part and something that will be addressed in 11g. Sub templates are now a first class citizen in the world of BIP, you can upload them and BIP will know what to do with them. But what do you do right now? The easiest place to put them where BIP can 'see' them is to create a directory under the xmlpserver install directory in the J2EE container e.g. $J2EE_HOME/xmlpserver/xmlpserver/subtemplates You can call it whatever you want but when the server is started up, that directory is accessible via a URL i.e. http://tdexter:9704/xmlpserver/subtemplates/mysub.rtf. You can therefore put it into the top of your main templates and call the sub template. <?import: http://tdexter:9704/xmlpserver/subtemplates/mysub.rtf?> Of course, you can drop them anywhere you want, they just need to be in a web server mountable directory. Enjoy the arugala!

  • Thinktecture.IdentityServer RC

    - by Your DisplayName here!
    I just uploaded the RC of IdentityServer to Codeplex. This release is feature complete and if I don’t get any bug reports this is also pretty much the final V1. Changes from B1 The configuration data access is now based on EF 4.1 code first. This makes it much easier to use different data stores. For RTM I will also provide a SQL script for SQL Server so you can move the configuration to a separate machine (e.g. for load balancing scenarios). I included the ASP.NET Universal Providers in the download. This adds official support for SQL Azure, SQL Server and SQL Compact for the membership, roles and profile features. Unfortunately the Universal Provider use a different schema than the original ASP.NET providers (that sucks btw!) – so I made them optional. If you want to use them go to web.config and uncomment the new provider. The relying party registration entries now have added fields to add extra data that you want to couple with the RP. One use case could be to give the UI a hint how the login experience should look like per RP. This allows to have a different look and feel for different relying parties. I also included a small helper API that you can use to retrieve the RP record based on the incoming WS-Federation query string. WS-Federation single sign out is now conforming to the spec. Certificate based endpoint identities for SSL endpoints are optional now. Added a initial configuration “wizard”. This sets up the signing certificate, issuer URI and site title on the first run. Installation This is still a “developer” release – that means it ships with source code that you have to build it etc. But from that point it should be a little more straightforward as it used to be: Make sure SSL is configured correctly for IIS Map the WebSite directory to a vdir in IIS Run the web site. This should bring up the initial configuration Make sure the worker process account has access to the signing certificate private key Make sure all your users are in the “IdentityServerUsers” role in your role store. Administrators need the “IdentityServerAdministrators” role That should be it. A proper documentation will be hopefully available soon (any volunteers?). Please provide feedback! thanks!

  • JWT Token Security with Fusion Sales Cloud

    - by asantaga
    When integrating SalesCloud with a 3rd party application you often need to pass the users identity to the 3rd party application so that  The 3rd party application knows who the user is The 3rd party application needs to be able to do WebService callbacks to Sales Cloud as that user.  Until recently without using SAML, this wasn't easily possible and one workaround was to pass the username, potentially even the password, from Sales Cloud to the 3rd party application using URL parameters.. With Oracle Fusion R8 we now have a proper solution and that is called "JWT Token support". This is based on the industry JSON Web Token standard , for more information see here JWT Works by allowing the user the ability to generate a token (lasts a short period of time) for a specific application. This token is then passed to the 3rd party application as a GET parameter.  The 3rd party application can then call into SalesCloud and use this token for all webservice calls, the calls will be executed as the user who generated the token in the first place, or they can call a special HR WebService (UserService-findSelfUserDetails() ) with the token and Fusion will respond with the users details. Some more details  The following will go through the scenario that you want to embed a 3rd party application within a WebContent frame (iFrame) within the opportunity screen.  1. Define your application using the topology manager in setup and maintenance  See this documentation link on topology manager 2. From within your groovy script which defines the iFrame you wish to embed, write some code which looks like this : def thirdpartyapplicationurl = oracle.topologyManager.client.deployedInfo.DeployedInfoProvider.getEndPoint("My3rdPartyApplication" )def crmkey= (new oracle.apps.fnd.applcore.common.SecuredTokenBean().getTrustToken())def url = thirdpartyapplicationurl +"param1="+OptyId+"&jwt ="+crmkeyreturn (url)  This snippet generates a URL which contains The Hostname/endpoint of the 3rd party application Two Parameters The opportunityId stored in parameter "param1" The JWT Token store in  parameter "jwt" 3. From your 3rd Party Application you now have two options Execute a webservice call by first setting the header parameter "Authentication" to the JWT token. The webservice call will be executed against Fusion Applications "As" the user who execute the process To find out "Who you are" , set the header parameter to "Authentication" and execute the special webservice call findSelfUserDetails(), in the UserDetailsService For more information  Oracle Sales Cloud Documentation , specific chapter on JWT Token OTN samples, specifically the Rich UI With JWT Token Sample Oracle Fusion Applications General Documentation

  • New Options for MySQL High Availability

    - by Mat Keep
    Data is the currency of today’s web, mobile, social, enterprise and cloud applications. Ensuring data is always available is a top priority for any organization – minutes of downtime will result in significant loss of revenue and reputation. There is not a “one size fits all” approach to delivering High Availability (HA). Unique application attributes, business requirements, operational capabilities and legacy infrastructure can all influence HA technology selection. And then technology is only one element in delivering HA – “People and Processes” are just as critical as the technology itself. For this reason, MySQL Enterprise Edition is available supporting a range of HA solutions, fully certified and supported by Oracle. MySQL Enterprise HA is not some expensive add-on, but included within the core Enterprise Edition offering, along with the management tools, consulting and 24x7 support needed to deliver true HA. At the recent MySQL Connect conference, we announced new HA options for MySQL users running on both Linux and Solaris: - DRBD for MySQL - Oracle Solaris Clustering for MySQL DRBD (Distributed Replicated Block Device) is an open source Linux kernel module which leverages synchronous replication to deliver high availability database applications across local storage. DRBD synchronizes database changes by mirroring data from an active node to a standby node and supports automatic failover and recovery. Linux, DRBD, Corosync and Pacemaker, provide an integrated stack of mature and proven open source technologies. DRBD Stack: Providing Synchronous Replication for the MySQL Database with InnoDB Download the DRBD for MySQL whitepaper to learn more, including step-by-step instructions to install, configure and provision DRBD with MySQL Oracle Solaris Cluster provides high availability and load balancing to mission-critical applications and services in physical or virtualized environments. With Oracle Solaris Cluster, organizations have a scalable and flexible solution that is suited equally to small clusters in local datacenters or larger multi-site, multi-cluster deployments that are part of enterprise disaster recovery implementations. The Oracle Solaris Cluster MySQL agent integrates seamlessly with MySQL offering a selection of configuration options in the various Oracle Solaris Cluster topologies. Putting it All Together When you add MySQL Replication and MySQL Cluster into the HA mix, along with 3rd party solutions, users have extensive choice (and decisions to make) to deliver HA services built on MySQL To make the decision process simpler, we have also published a new MySQL HA Solutions Guide. Exploring beyond just the technology, the guide presents a methodology to select the best HA solution for your new web, cloud and mobile services, while also discussing the importance of people and process in ensuring service continuity. This is subject recently presented at Oracle Open World, and the slides are available here. Whatever your uptime requirements, you can be sure MySQL has an HA solution for your needs Please don't hesitate to let us know of your HA requirements in the comments section of this blog. You can also contact MySQL consulting to learn more about their HA Jumpstart offering which will help you scope out your scaling and HA requirements.

  • Ubuntu boots to terminal on start up

  • Adding Attributes to Generated Classes

    ASP.NET MVC 2 adds support for data annotations, implemented via attributes on your model classes.  Depending on your design, you may be using an OR/M tool like Entity Framework or LINQ-to-SQL to generate your entity classes, and you may further be using these entities directly as your Model.  This is fairly common, and alleviates the need to do mapping between POCO domain objects and such entities (though there are certainly pros and cons to using such entities directly). As an example, the current version of the NerdDinner application (available on CodePlex at nerddinner.codeplex.com) uses Entity Framework for its model.  Thus, there is a NerdDinner.edmx file in the project, and a generated NerdDinner.Models.Dinner class.  Fortunately, these generated classes are marked as partial, so you can extend their behavior via your own partial class in a separate file.  However, if for instance the generated Dinner class has a property Title of type string, you cant then add your own Title of type string for the purpose of adding data annotations to it, like this: public partial class Dinner { [Required] public string Title { get;set; } } This will result in a compilation error, because the generated Dinner class already contains a definition of Title.  How then can we add attributes to this generated code?  Do we need to go into the T4 template and add a special case that says if were generated a Dinner class and it has a Title property, add this attribute?  Ick. MetadataType to the Rescue The MetadataType attribute can be used to define a type which contains attributes (metadata) for a given class.  It is applied to the class you want to add metadata to (Dinner), and it refers to a totally separate class to which youre free to add whatever methods and properties you like.  Using this attribute, our partial Dinner class might look like this: [MetadataType(typeof(Dinner_Validation))] public partial class Dinner {}   public class Dinner_Validation { [Required] public string Title { get; set; } } In this case the Dinner_Validation class is public, but if you were concerned about muddying your API with such classes, it could instead have been created as a private class within Dinner.  Having the validation attributes specified in their own class (with no other responsibilities) complies with the Single Responsibility Principle and makes it easy for you to test that the validation rules you expect are in place via these annotations/attributes. Thanks to Julie Lerman for her help with this.  Right after she showed me how to do this, I realized it was also already being done in the project I was working on. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

Providing emergency medical assistance is impossible since you can't tell which are bitwise copies and which are just pointing at others and saying "That's me, over there."   FORTRAN You shoot yourself in each toe, iteratively, until you run out of toes, then you read in the next foot and repeat. If you run out of bullets, you continue anyway because you have no exception-handling facility.   Modula-2 After realizing that you can't actually accomplish anything in this language, you shoot yourself in the head.   COBOL USEing a COLT 45 HANDGUN, AIM gun at LEG.FOOT, THEN place ARM.HAND.FINGER on HANDGUN.TRIGGER and SQUEEZE. THEN return HANDGUN to HOLSTER. CHECK whether shoelace needs to be retied.   Lisp You shoot yourself in the appendage which holds the gun with which you shoot yourself in the appendage which holds the gun with which you shoot yourself in the appendage which holds...   BASIC Shoot yourself in the foot with a water pistol. On big systems, continue until entire lower body is waterlogged.   Forth Foot yourself in the shoot.   APL You shoot yourself in the foot; then spend all day figuring out how to do it in fewer characters.   Pascal The compiler won't let you shoot yourself in the foot.   Snobol If you succeed, shoot yourself in the left foot. If you fail, shoot yourself in the right foot.   HyperTalk Put the first bullet of the gun into foot left of leg of you. Answer the result.   Prolog You tell your program you want to be shot in the foot. The program figures out how to do it, but the syntax doesn't allow it to explain.   370 JCL You send your foot down to MIS with a 4000-page document explaining how you want it to be shot. Three years later, your foot comes back deep-fried.   FORTRAN-77 You shoot yourself in each toe, iteratively, until you run out of toes, then you read in the next foot and repeat. If you run out of bullets, you continue anyway because you still can't do exception-processing.   Modula-2 (alternative) You perform a shooting on what might be currently a foot with what might be currently a bullet shot by what might currently be a gun.   BASIC (compiled) You shoot yourself in the foot with a BB using a SCUD missile launcher.   Visual Basic You'll really only appear to have shot yourself in the foot, but you'll have so much fun doing it that you won't care.   Forth (alternative) BULLET DUP3 * GUN LOAD FOOT AIM TRIGGER PULL BANG!

The act of shooting the original foot then changes your hand/bullet into yet another foot (a left foot).   Prolog (alternative) You attempt to shoot yourself in the foot, but the bullet, failing to find its mark, backtracks to the gun, which then explodes in your face.   COMAL You attempt to shoot yourself in the foot with a water pistol, but the bore is clogged, and the pressure build-up blows apart both the pistol and your hand. or draw_pistol aim_at_foot(left) pull_trigger hop(swearing)   Scheme As Lisp, but none of the other appendages are aware of this happening.   Algol You shoot yourself in the foot with a musket. The musket is aesthetically fascinating and the wound baffles the adolescent medic in the emergency room.   Ada If you are dumb enough to actually use this language, the United States Department of Defense will kidnap you, stand you up in front of a firing squad and tell the soldiers, "Shoot at the feet." or The Department of Defense shoots you in the foot after offering you a blindfold and a last cigarette. or After correctly packaging your foot, you attempt to concurrently load the gun, pull the trigger, scream and shoot yourself in the foot. When you try, however, you discover that your foot is of the wrong type. or After correctly packing your foot, you attempt to concurrently load the gun, pull the trigger, scream, and confidently aim at your foot knowing it is safe. However the cordite in the round does an Unchecked Conversion, fires and shoots you in the foot anyway.   Eiffel   You create a GUN object, two FOOT objects and a BULLET object. The GUN passes both the FOOT objects a reference to the BULLET. The FOOT objects increment their hole counts and forget about the BULLET. A little demon then drives a garbage truck over your feet and grabs the bullet (both of it) on the way. Smalltalk You spend so much time playing with the graphics and windowing system that your boss shoots you in the foot, takes away your workstation and makes you develop in COBOL on a character terminal. or You send the message shoot to gun, with selectors bullet and myFoot. A window pops up saying Gunpowder doesNotUnderstand: spark. After several fruitless hours spent browsing the methods for Trigger, FiringPin and IdealGas, you take the easy way out and create ShotFoot, a subclass of Foot with an additional instance variable bulletHole. Object Oriented Pascal You perform a shooting on what might currently be a foot with what might currently be a bullet fired from what might currently be a gun.   PL/I You consume all available system resources, including all the offline bullets. The Data Processing & Payroll Department doubles its size, triples its budget, acquires four new mainframes and drops the original one on your foot. Postscript foot bullets 6 locate loadgun aim gun shoot showpage or It takes the bullet ten minutes to travel from the gun to your foot, by which time you're long since gone out to lunch. The text comes out great, though.   PERL You stab yourself in the foot repeatedly with an incredibly large and very heavy Swiss Army knife. or You pick up the gun and begin to load it. The gun and your foot begin to grow to huge proportions and the world around you slows down, until the gun fires. It makes a tiny hole, which you don't feel. Assembly Language You crash the OS and overwrite the root disk. The system administrator arrives and shoots you in the foot. After a moment of contemplation, the administrator shoots himself in the foot and then hops around the room rabidly shooting at everyone in sight. or You try to shoot yourself in the foot only to discover you must first reinvent the gun, the bullet, and your foot.or The bullet travels to your foot instantly, but it took you three weeks to load the round and aim the gun.   BCPL You shoot yourself somewhere in the leg -- you can't get any finer resolution than that. Concurrent Euclid You shoot yourself in somebody else's foot.   Motif You spend days writing a UIL description of your foot, the trajectory, the bullet and the intricate scrollwork on the ivory handles of the gun. When you finally get around to pulling the trigger, the gun jams.   Powerbuilder While attempting to load the gun you discover that the LoadGun system function is buggy; as a work around you tape the bullet to the outside of the gun and unsuccessfully attempt to fire it with a nail. In frustration you club your foot with the butt of the gun and explain to your client that this approximates the functionality of shooting yourself in the foot and that the next version of Powerbuilder will fix it.   Standard ML By the time you get your code to typecheck, you're using a shoot to foot yourself in the gun.   MUMPS You shoot 583149 AK-47 teflon-tipped, hollow-point, armour-piercing bullets into even-numbered toes on odd-numbered feet of everyone in the building -- with one line of code. Three weeks later you shoot yourself in the head rather than try to modify that line.   Java You locate the Gun class, but discover that the Bullet class is abstract, so you extend it and write the missing part of the implementation. Then you implement the ShootAble interface for your foot, and recompile the Foot class. The interface lets the bullet call the doDamage method on the Foot, so the Foot can damage itself in the most effective way. Now you run the program, and call the doShoot method on the instance of the Gun class. First the Gun creates an instance of Bullet, which calls the doFire method on the Gun. The Gun calls the hit(Bullet) method on the Foot, and the instance of Bullet is passed to the Foot. But this causes an IllegalHitByBullet exception to be thrown, and you die.   Unix You shoot yourself in the foot or % ls foot.c foot.h foot.o toe.c toe.o % rm * .o rm: .o: No such file or directory % ls %   370 JCL (alternative) You shoot yourself in the head just thinking about it.   DOS JCL You first find the building you're in in the phone book, then find your office number in the corporate phone book. Then you have to write this down, then describe, in cubits, your exact location, in relation to the door (right hand side thereof). Then you need to write down the location of the gun (loading it is a proprietary utility), then you load it, and the COBOL program, and run them, and, with luck, it may be run tonight.   VMS   $ MOUNT/DENSITY=.45/LABEL=BULLET/MESSAGE="BYE" BULLET::BULLET$GUN SYS$BULLET $ SET GUN/LOAD/SAFETY=OFF/SIGHT=NONE/HAND=LEFT/CHAMBER=1/ACTION=AUTOMATIC/ LOG/ALL/FULL SYS$GUN_3$DUA3:[000000]GUN.GNU $ SHOOT/LOG/AUTO SYS$GUN SYS$SYSTEM:[FOOT]FOOT.FOOT   %DCL-W-ACTIMAGE, error activating image GUN -CLI-E-IMGNAME, image file $3$DUA240:[GUN]GUN.EXE;1 -IMGACT-F-NOTNATIVE, image is not an OpenVMS Alpha AXP image or %SYS-F-FTSHT, foot shot (fifty lines of traceback omitted) sh,csh, etc You can't remember the syntax for anything, so you spend five hours reading manual pages, then your foot falls asleep. You shoot the computer and switch to C.   Apple System 7 Double click the gun icon and a window giving a selection for guns, target areas, plus balloon help with medical remedies, and assorted sound effects. Click "shoot" button and a small bomb appears with note "Error of Type 1 has occurred."   Windows 3.1 Double click the gun icon and wait. Eventually a window opens giving a selection for guns, target areas, plus balloon help with medical remedies, and assorted sound effects. Click "shoot" button and a small box appears with note "Unable to open Shoot.dll, check that path is correct."   Windows 95 Your gun is not compatible with this OS and you must buy an upgrade and install it before you can continue. Then you will be informed that you don't have enough memory.   CP/M I remember when shooting yourself in the foot with a BB gun was a big deal.   DOS You finally found the gun, but can't locate the file with the foot for the life of you.   MSDOS You shoot yourself in the foot, but can unshoot yourself with add-on software.   Access You try to point the gun at your foot, but it shoots holes in all your Borland distribution diskettes instead.   Paradox Not only can you shoot yourself in the foot, your users can too.   dBase You squeeze the trigger, but the bullet moves so slowly that by the time your foot feels the pain, you've forgotten why you shot yourself anyway. or You buy a gun. Bullets are only available from another company and are promised to work so you buy them. Then you find out that the next version of the gun is the one scheduled to actually shoot bullets.   DBase IV, V1.0 You pull the trigger, but it turns out that the gun was a poorly designed hand grenade and the whole building blows up.   SQL You cut your foot off, send it out to a service bureau and when it returns, it has a hole in it but will no longer fit the attachment at the end of your leg. or Insert into Foot Select Bullet >From Gun.Hand Where Chamber = 'LOADED' And Trigger = 'PULLED'   Clipper You grab a bullet, get ready to insert it in the gun so that you can shoot yourself in the foot and discover that the gun that the bullets fits has not yet been built, but should be arriving in the mail _REAL_SOON_NOW_. Oracle The menus for coding foot_shooting have not been implemented yet and you can't do foot shooting in SQL.   English You put your foot in your mouth, then bite it off. (For those who don't know, English is a McDonnell Douglas/PICK query language which allegedly requires 110% of system resources to run happily.) Revelation [an implementation of the PICK Operating System] You'll be able to shoot yourself in the foot just as soon as you figure out what all these bullets are for.   FlagShip Starting at the top of your head, you aim the gun at yourself repeatedly until, half an hour later, the gun is finally pointing at your foot and you pull the trigger. A new foot with a hole in it appears but you can't work out how to get rid of the old one and your gun doesn't work anymore.   FidoNet You put your foot in your mouth, then echo it internationally.   PicoSpan [a UNIX-based computer conferencing system] You can't shoot yourself in the foot because you're not a host. or (host variation) Whenever you shoot yourself in the foot, someone opens a topic in policy about it.   Internet You put your foot in your mouth, shoot it, then spam the bullet so that everybody gets shot in the foot.   troff rmtroff -ms -Hdrwp | lpr -Pwp2 & .*place bullet in footer .B .NR FT +3i .in 4 .bu Shoot! .br .sp .in -4 .br .bp NR HD -2i .*   Genetic Algorithms You create 10,000 strings describing the best way to shoot yourself in the foot. By the time the program produces the optimal solution, humans have evolved wings and the problem is moot.   CSP (Communicating Sequential Processes) You only fail to shoot everything that isn't your foot.   MS-SQL Server MS-SQL Server’s gun comes pre-loaded with an unlimited supply of Teflon coated bullets, and it only has two discernible features: the muzzle and the trigger. If that wasn't enough, MS-SQL Server also puts the gun in your hand, applies local anesthetic to the skin of your forefinger and stitches it to the gun's trigger. Meanwhile, another process has set up a spinal block to numb your lower body. It will then proceeded to surgically remove your foot, cryogenically freeze it for preservation, and attach it to the muzzle of the gun so that no matter where you aim, you will shoot your foot. In order to avoid shooting yourself in the foot, you need to unstitch your trigger finger, remove your foot from the muzzle of the gun, and have it surgically reattached. Then you probably want to get some crutches and go out to buy a book on SQL Server Performance Tuning.   Sybase Sybase's gun requires assembly, and you need to go out and purchase your own clip and bullets to load the gun. Assembly is complicated by the fact that Sybase has hidden the gun behind a big stack of reference manuals, but it hasn't told you where that stack is. While you were off finding the gun, assembling it, buying bullets, etc., Sybase was also busy surgically removing your foot and cryogenically freezing it for preservation. Instead of attaching it to the muzzle of the gun, though, it packed your foot on dry ice and sent it UPS-Ground to an unnamed hookah bar somewhere in the middle east. In order to shoot your foot, you must modify your gun with a GPS system for targeting and hire some guy named "Indy" to find the hookah bar and wire the coordinates back to you. By this time, you've probably become so daunted at the tasks stand between you and shooting your foot that you hire a guy who's read all the books on Sybase to help you shoot your foot. If you're lucky, he'll be smart enough both to find your foot and to stop you from shooting it.   Magic software You spend 1 week looking up the correct syntax for GUN. When you find it, you realise that GUN will not let you shoot in your own foot. It will allow you to shoot almost anything but your foot. You then decide to build your own gun. You can't use the standard barrel since this will only allow for standard bullets, which will not fire if the barrel is pointed at your foot. After four weeks, you have created your own custom gun. It blows up in your hand without warning, because you failed to initialise the safety catch and it doesn't know whether the initial state is "0", 0, NULL, "ZERO", 0.0, 0,0, "0.0", or "0,00". You fix the problem with your remaining hand by nesting 12 safety catches, and then decide to build the gun without safety catch. You then shoot the management and retire to a happy life where you code in languages that will allow you to shoot your foot in under 10 days.FirefoxLets you shoot yourself in as many feet as you'd like, while using multiple great addons! IEA moving target in terms of standard ammunition size and doesn't always work properly with non-Microsoft ammunition, so sometimes you shoot something other than your foot. However, it's the corporate world's standard foot-shooting apparatus. Hackers seem to enjoy rigging websites up to trigger cascading foot-shooting failures. Windows 98 About the same as Windows 95 in terms of overall bullet capacity and triggering mechanisms. Includes updated DirectShot API. A new version was released later on to support USB guns, Windows 98 SE.WPF:You get your baseball glove and a ball and you head out to your backyard, where you throw balls to your pitchback. Then your unkempt-haired-cargo-shorts-and-sandals-with-white-socks-wearing neighbor uses XAML to sculpt your arm into a gun, the ball into a bullet and the pitchback into your foot. By now, however, only the neighbor can get it to work and he's only around from 6:30 PM - 3:30 AM. LOGO: You very carefully lay out the trajectory of the bullet. Then you start the gun, which fires very slowly. You walk precisely to the point where the bullet will travel and wait, but just before it gets to you, your class time is up and one of the other kids has already used the system to hack into Sony's PS3 network. Flash: Someone has designed a beautiful-looking gun that anyone can shoot their feet with for free. It weighs six hundred pounds. All kinds of people are shooting themselves in the feet, and sending the link to everyone else so that they can too. That is, except for the criminals, who are all stealing iOS devices that the gun won't work with.APL: Its (mostly) all greek to me. Lisp: Place ((gun in ((hand sight (foot then shoot))))) (Lots of Insipid Stupid Parentheses)Apple OS/X and iOS Once a year, Steve Jobs returns from sick leave to tell millions of unwavering fans how they will be able to shoot themselves in the foot differently this year. They retweet and blog about it ad nauseam, and wait in line to be the first to experience "shoot different".Windows ME Usually fails, even at shooting you in the foot. Yo dawg, I heard you like shooting yourself in the foot. So I put a gun in your gun, so you can shoot yourself in the foot while you shoot yourself in the foot. (Okay, I'm not especially proud of this joke.) Windows 2000 Now you really do have to log in, before you are allowed to shoot yourself in the foot.Windows XPYou thought you learned your lesson: Don't use Windows ME. Then, along came this new creature, built on top of Windows NT! So you spend the next couple days installing antivirus software, patches and service packs, just so you can get that driver to install, and then proceed to shoot yourself in the foot. Windows Vista Newer! Glossier! Shootier! Windows 7 The bullets come out a lot smoother. Active Directory Each bullet now has an attached Bullet Identifier, and can be uniquely identified. Policies can be applied to dictate fragmentation, and the gun will occasionally have a confusing delay after the trigger has been pulled. PythonYou try to use import foot; foot.shoot() only to realize that's only available in 3.0, to which you can't yet upgrade from 2.7 because of all those extension libs lacking support. Solaris Shoots best when used on SPARC hardware, but still runs the trigger GUI under Java. After weeks of learning the appropriate STOP command to prevent the trigger from automatically being pressed on boot, you think you've got it under control. Then the one time you ever use dtrace, it hits a bug that fires the gun. MySQL The feature that allows you to shoot yourself in the foot has been in development for about 6 years, and they are adding it into the next version, which is coming out REAL SOON NOW, promise! But you can always check it out of source control and try it yourself (just not in any environment where data integrity is important because it will probably explode.) PostgreSQLAllows you to have a smug look on your face while you shoot yourself in the foot, because those MySQL guys STILL don't have that feature. NoSQL Barrel? Who needs a barrel? Just put the bullet on your foot, and strike it with a hammer. See? It's so much simpler and more efficient that way. You can even strike multiple bullets in one swing if you swing with a good enough arc, because hammers are easy to use. Getting them to synchronize is a little difficult, though.Eclipse There are about a dozen different packages for shooting yourself in the foot, with weird interdependencies on outdated components. Once you finally navigate the morass and get one installed, you then have something to look at while you shoot yourself in the foot with that package: You can watch the screen redraw.Outlook Makes it really easy to let everyone know you shot yourself in the foot!Shooting yourself in the foot using delegates.You really need to shoot yourself in the foot but you hate firearms (you don't want any dependency on the specifics of shooting) so you delegate it to somebody else. You don't care how it is done as long is shooting your foot. You can do it asynchronously in case you know you may faint so you are called back/slapped in the face by your shooter/friend (or background worker) when everything is done.C#You prepare the gun and the bullet, carefully modeling all of the physics of a bullet traveling through a foot. Just before you're about to pull the trigger, you stumble on System.Windows.BodyParts.Foot.ShootAt(System.Windows.Firearms.IGun gun) in the extended framework, realize you just wasted the entire afternoon, and shoot yourself in the head.PHP<?phprequire("foot_safety_check.php");?><!DOCTYPE HTML><html><head> <!--Lower!--><title>Shooting me in the foot</title></head> <body> <!--LOWER!!!--><leg> <!--OK, I made this one up...--><footer><?php echo (dungSift($_SERVER['HTTP_USER_AGENT'], "ie"))?("Your foot is safe, but you might want to wear a hard hat!"):("<div class=\"shot\">BANG!</div>"); ?></footer></leg> </body> </html>
