  • Complete deployment to AWS

    - by Ionut
    I'm trying to deploy a Java Application to AWS free tier. I need the following: RDS provider. Using MySQL client S3 service. This is required for the Lucene Index and image uploading SES service. I need to be able to send emails to new registered users. Namecheap is my domain provider. EC2 instance Elastic Beanstalk instance. I managed to create an EC2 instance, upload the WAR file and link it to the Namecheap domain. However I find it difficult to link the other instances to the current application. I find the documentation a little messy and I can't find the right way to do this. Can you provide a simple walk through to deployment for this use case? Thanks!

  • Interacting with IE using sendkeys from Excel

    - by Thomas Egan
    I'm trying to write an application which uses values from excel and then switches to a web application using sendkeys. The problem I am having is that I cannot used sendkeys ("{ENTER}") or sendkeys ("^o") as I don't have the access for that. I'm trying to automate a very trivial admin task. I've thought about using the mouse to interact with the links as well as pausing and waiting for the user to just hit return but so far have been unable to come up with a solution. Do you think there is anyway around this? I have some VBA knowledge (enough to get me this far) but not a great deal.

  • How can we integrate use of a foreign language into an internship?

    - by ChrisRamakers
    We have a few interns here that have orders from college to integrate speaking, reading, and writing French into their internship. All of them are working on developing their own web application, and I'm wondering how we can integrate French into their projects. Here are some things I've come up with: Translate the whole project front-end to French Write French documentation for the project Promote the application in a French community Speak French (exclusively?) to our project managers Any other ideas or suggestions? Does anyone else have experience with this?

  • Ubuntu chroot “No such file or directory”

    - by Paris
    Hi there. I hace a web application where I create some folders on my server and put executables there. Then I try to wun them with chroot but I get a message that access is denied there. I tried chroot -r 777 blah blah.... and then I get a message that the folder or the file that I call (sudo chroot mydirectory myfile_inside_Mydirectory) does not exist. This happens only when I call chroot on folders created by the web server. My web application is in php and I use: shell_exec("cp -R /var/www/comp/prison/bin $dir"); shell_exec("cp -R /var/www/comp/prison/lib $dir"); shell_exec("cp /var/www/janitor.out $dir/janitor.out"); shell_exec("sudo chmod -R 777 $dir"); $process = proc_open("sudo chroot $dir janitor.out", $descriptorspec, $pipes); sudo does not need password.

  • Java and web pages

    - by Filippo
    Hello everyone and thank you in advance for the answers. I have a question concerning not how to do something, but with which instruments. Let's say, I want to write a simple application in Java that connects to a news website (e.g. CNN), parses the html document and prints on screen the news. Another example : my application retrieves and prints on screen soccer results from Eurosports. What do I need to do that? External libraries? Or maybe what I'm looking for is already included in JavaEE? Could this be helpful? http://jsoup.org/<< Thank you everyone again and have a nice day.

  • Unity 3D - Error BCE0019 , " 'paused' is not a member of PauseScript"

    - by user3666251
    I am trying to make a game for Android in Unity. Came to the part where I have to make a pause menu option. Made a GUITexture and placed it on the top right side of the screen then I attached this script to it : #pragma strict function OnMouseDown(){ this.paused = !this.paused; } function OnGUI(){ if(this.paused){ if (GUI.Button(Rect(10,10,100,50),"Restart")){ Application.LoadLevel(Application.loadedLevel); } // Insert the rest of the pause menu logic } } It gives me this error : "Assets/Scripts/PauseScript.js(4,10): BCE0019: 'paused' is not a member of 'PauseScript'. " "PauseScript" is the name of my pause script. Thank you.

  • design a model for a system of dependent variables

    - by dbaseman
    I'm dealing with a modeling system (financial) that has dozens of variables. Some of the variables are independent, and function as inputs to the system; most of them are calculated from other variables (independent and calculated) in the system. What I'm looking for is a clean, elegant way to: define the function of each dependent variable in the system trigger a re-calculation, whenever a variable changes, of the variables that depend on it A naive way to do this would be to write a single class that implements INotifyPropertyChanged, and uses a massive case statement that lists out all the variable names x1, x2, ... xn on which others depend, and, whenever a variable xi changes, triggers a recalculation of each of that variable's dependencies. I feel that this naive approach is flawed, and that there must be a cleaner way. I started down the path of defining a CalculationManager<TModel> class, which would be used (in a simple example) something like as follows: public class Model : INotifyPropertyChanged { private CalculationManager<Model> _calculationManager = new CalculationManager<Model>(); // each setter triggers a "PropertyChanged" event public double? Height { get; set; } public double? Weight { get; set; } public double? BMI { get; set; } public Model() { _calculationManager.DefineDependency<double?>( forProperty: model => model.BMI, usingCalculation: (height, weight) => weight / Math.Pow(height, 2), withInputs: model => model.Height, model.Weight); } // INotifyPropertyChanged implementation here } I won't reproduce CalculationManager<TModel> here, but the basic idea is that it sets up a dependency map, listens for PropertyChanged events, and updates dependent properties as needed. I still feel that I'm missing something major here, and that this isn't the right approach: the (mis)use of INotifyPropertyChanged seems to me like a code smell the withInputs parameter is defined as params Expression<Func<TModel, T>>[] args, which means that the argument list of usingCalculation is not checked at compile time the argument list (weight, height) is redundantly defined in both usingCalculation and withInputs I am sure that this kind of system of dependent variables must be common in computational mathematics, physics, finance, and other fields. Does someone know of an established set of ideas that deal with what I'm grasping at here? Would this be a suitable application for a functional language like F#? Edit More context: The model currently exists in an Excel spreadsheet, and is being migrated to a C# application. It is run on-demand, and the variables can be modified by the user from the application's UI. Its purpose is to retrieve variables that the business is interested in, given current inputs from the markets, and model parameters set by the business.

  • LuaJit FFI and hiding C implementation details

    - by wirrbel
    I would like to extend an application using LuaJit FFI. Having seen http://luajit.org/ext_ffi_tutorial.html this is surprisingly easy when comparing this to the Lua C API. So far so good. However I do not plainly want to wrap C functions but provide a higher level API to users writing scripts for the application. Especially I do not want users to be able to access "primitives", i.e. the ffi.* namespace. Is this possible or will that ffi namespace be available to user's Lua scripts? On the issue of Sandboxing Lua I found http://lua-users.org/wiki/SandBoxes which is not talking about FFI though. Furthermore, the plan I have described above is assuming that the introduction of abstraction layers happens on the lua side of code. Is this an advisable approach or would you rather abstract functionality on the statically compiled code (on the C-side)?

  • Private Cloud: Putting some method behind the madness

    - by Sudip Datta
    Finally, I decided to join the blogging community. And what could be a better time to start than the week after OpenWorld 2012. 50K+ attendees, demonstrations, speaker sessions and a whole lot of buzz on Oracle Cloud..It was raining clouds in this year's Openworld. I am not here to write about Oracle's cloud strategy in general, but on Enterprise Manager's cloud management capabilities. This year's Openworld was the first after we announced the 12c Cloud Control and we were happy to share the stage with quite a few early adopters. Stay tuned for videos from our customers and partners, I will post them as they get published. I met a number of platform administrators in Oracle-DBAs, Middleware Admins, SOA Admins...The cloud has affected them all, at least to the point where it beckoned more than just curiosity..Most IT infrastructure are already heavily virtualized (on VMWare and on others including Oracle VM), and some would claim they are already on “cloud” (at least their Sysadmins told them so). But none of them were confident of the benefits because their pain points continued to grow.. Isn't cloud supposed to ease those? Instead, they were chasing hundreds of databases running on hundreds of VMs, often with as much certainty propounded by Heisenberg. What happened to the age-old IT discipline around administration, compliance, configuration management? VMs are great for what they are. I personally think they have opened the doors to new approaches in which an application stack gets provisioned and updated. In fact, Enterprise Manager 12c is possibly the only tool out there that can provision full-fledged application as VM Assemblies. In this year's Openworld, customers talked on how they provisioned RAC and Siebel assemblies, which as the techies out there know, are not trivial (hearing provisioning time for Siebel down from weeks to hours was gratifying indeed). However, I do have an issue with a "one-size fits all" approach to cloud. In a week's span, I met several personas: Project owners requiring an EC2 like VM instance for their projects Admins needing the same for Sparc-Solaris. DBAs requiring dedicated databases for new projects APEX Developers needing just a ready-to-consume schema as a service Java Developers looking for a runtime platform QA engineers needing a fast clone of their production environment If you drill down further, you will end up peeling more layers of the details. For example, the requirements for Load testing and Functional testing are very different. For Load testing the test environment should ideally be the same as the production. You shouldn't run production on Exadata and load test on a VM; they will just not be good representations of one another. For Functional testing it does not possibly matter. DBAs seem to be at the worst affected of the lot. It seems they have been asked to choose between agile provisioning and  faster runtime performance. And in some cases, it is really a Hobson's choice, because their infrastructure provider made no distinction between the OLTP application and the Virtual desktop! Sad indeed. When one looks at the portfolio of services that we already offer (vanilla IaaS, VM Assembly based PaaS, DBaaS) or have announced (Java PaaS, Instant Cloning, Schema-aaS), one can possibly think that we are trying to be the "renaissance man" ! Well I would have possibly digested that had it not been for the various personas that I described above. Getting the use cases right is very important for an application such as cloud management. We iterate and iterate over these over and over again and re-validate them in CABs (Customer Advisory Boards). We consider over the major aspects of tenancy: service placement, resource isolation (can a tenant execute an expensive SQL and run away with all the resources), quota and security. We, in Engineering, keep reminding ourselves that we are dealing with enterprise clouds. We owe it to our customer base ! In the coming posts, I will drill down more into each of the services. In the meanwhile, here are some collateral and  demos for starters with EM 12c. http://www.oracle.com/technetwork/oem/cloud-mgmt/index.html Sudip Datta The views expressed here are my own and do not necessarily reflect the views of Oracle.
