  • What kind of specific projects can I do to master bitwise operations in C++? Also is there a canonical book? [closed]

    - by Ford
    I don't use C++ or bitwise operations at my current job but I'm thinking of applying to companies where it is a requirement to be fluent with them (on their tests anyway). So my question is: Can anyone suggest a project which will require gaining a fluency in bitwise operations to complete? On a side note, is there a canonical book on optimization techniques using bitwise operations since that seems to be an important use of them?

  • Where can i get the openal sdk for c++?

    - by Peter Short
    The OpenAL site I'm looking at is a crappy outdated and broken sharepoint portal and the SDK in the downloads section give me a 500 html code when i request it. http://connect.creativelabs.com/openal/Downloads/OpenAL11CoreSDK.zip I found an OpenAL SDK on a softpedia and it has headers but not alu.h or alut.h which the tutorials I'm looking at apparently require for loading wavs etc. What am I missing? Is OpenAL dead or something?

  • Questions about Microsoft's new Cloud certification

    - by makerofthings7
    I'm evaluating taking the cloud certification exams from Microsoft, and have a few questions How highly do you think employers will value this exam? What job roles would require this cert? In your personal experience, how would this certification be weighed against other factors such as real world experience, other certifications, and having a Bachelors degree? If you mention that other certifications are more valued, which ones are they?

  • Case Management Patterns with Oracle Unified Business Process Management Suite

    - by Ajay Khanna
    Contributed by Heidi Buelow, Oracle Product Management Case Management was a hot topic all week at Oracle OpenWorld so I was excited to share our current features and upcoming plans at the session Thursday morning on Case Management Patterns with Oracle Unified Business Process Management Suite.  My colleague, Ravi Rangaswamy, the Case Management Development Manager, and I, Heidi Buelow, the Case Management Product Manager, discussed case management use case patterns with an interested audience.  We also talked about the current BPM Suite offering for Case Managment and showed a demo of our upcoming release where Case Management becomes a first class component in a BPM composite application. Case Management use case patterns cover a wide range of horizontal applications such as Accounts Payable, Dispute Resolution, Call Center, Employee OnBoarding, and many vertical applications in domains and industries such as Public Sector services, Insurance claims, and Healthcare.  Really, it is any use case where the resolution of a request may require a knowledge worker making decisions using experienced judgement in the current situation.  This allows for expidited care and customer satisfaction, both being highly valued for consumer loyalty, regulatory compliance, and efficient resolution. Today, BPM Suite provides the tools for creating Case Management applications using BPMN 2.0, Business Rules, and rich BAM and Case Analytics.  The Process Composer provides the agility to change rules and processes by the business users.  The case manager and case workers have the flexibilty they need.  With integrated content management and the concept of a BPM Process Spaces instance (case) space, the current release enables case management use case applications. In the next release, Case Management becomes a first class component. By this, we mean, Case is a separate component in the composite.  We are adding case attributes such as milestones, case events, case stakeholders, and more, providing a rich toolset for the use cases that require a flexible Case Management approach.  Activites become available according to the conditions that you specify and information can be protected by permissions indicated.  In BPM Studio, you design a Case and associate all of the attributes and activities that are needed, yet, at runtime you have the flexibility to add and change these as needed. We enjoyed sharing Case Management and it was well received by the audience.  The presentation is available online and we have viewlets of the demo that will be available at release time.

  • How to implement an email unsubscribe system for a site with many kinds of emails?

    - by Mike Liu
    I'm working on a website that features many different types of emails. Users have accounts, and when logged in they have access to a setting page that they can use to customize what types of emails they receive. However, I'd like to also give users an easy way to unsubscribe directly in the emails they receive. I've looked into list unsubscribe headers as well as creating some type of one click link that would unsubscribe a user from that type of email without requiring login or further action. The later would probably require me to break convention and make changes to the database in response to a GET on the link. However, am I incorrect in thinking that either of these would require me to generate and permanently store a unique identifier in my database for every email I ever send, really complicating email delivery? Without that, I'm not sure how I would be able to uniquely identify a user and a type of email in order to change their email preferences, and this identifier would need to be stored forever as a user could have an email sitting in their inbox for a long time before they decide to act on it. Alternatively, I was considering having a no-login page for managing email preferences. In contrast to above where I would need one of these identifiers for each email, this would only need one identifier per user, with no generation or other action required on sending an email. All of these raise security issues, and they could potentially be used by people to tamper with others' email preferences. This could be mitigated somewhat by ensuring that the identifier is really difficult to guess. For the once per user identifier approach, I was considering generating the identifier by passing a user's ID through some type of encryption algorithm, is this a sound approach? For the per-email identifiers, perhaps I could use a user's ID appended to the time. However, even this would not eliminate the problem entirely, as this would really just be security through obscurity, and anyone with the URL could tamper, and in the end the main defense would have to be that most people aren't so bored as to tamper with other people's email preferences. Are there any other alternatives I've missed, or issues or solutions with these that anyone can provide insight on? What are best practices in this area?

  • Retrieving system information without WMI

    - by user94481
    I want to write an application where I can fetch system information like CPU-Z (for example) does. I don't want to rely on WMI, because I want to grab stuff like information about the manufacturing process of the GPU (like from a database) and I don't want to maintain this by myself, because that would require too much effort. I already came up with HWiNFO32 SDK but I wonder if there are any (maybe free) alternatives to it?

  • Oracle Tutor: Top 10 to Implement Sustainable Policies and Procedures

    - by emily.chorba(at)oracle.com
    Overview Your organization (executives, managers, and employees) understands the value of having written business process documents (process maps, procedures, instructions, reference documents, and form abstracts). Policies and procedures should be documented because they help to reduce the range of individual decisions and encourage management by exception: the manager only needs to give special attention to unusual problems, not covered by a specific policy or procedure. As more and more procedures are written to cover recurring situations, managers will begin to make decisions which will be consistent from one functional area to the next.Companies should take a project management approach when implementing an environment for a sustainable documentation program and do the following:1. Identify an Executive Champion2. Put together a winning team3. Assign ownership4. Centralize publishing5. Establish the Document Maintenance Process Up Front6. Document critical activities only7. Document actual practice8. Minimize documentation9. Support continuous improvement10. Keep it simple 1. Identify an Executive ChampionAppoint a top down driver. Select one key individual to be a mentor for the procedure planning team. The individual should be a senior manager, such as your company president, CIO, CFO, the vice-president of quality, manufacturing, or engineering. Written policies and procedures can be important supportive aids when known to express the thinking for the chief executive officer and / or the president and to have his or her full support. 2. Put Together a Winning TeamChoose a strong Project Management Leader and staff the procedure planning team with management members from cross functional groups. Make sure team members have the responsibility - and the authority - to make things happen.The winning team should consist of the Documentation Project Manager, Document Owners (one for each functional area), a Document Controller, and Document Specialists (as needed). The Tutor Implementation Guide has complete job descriptions for these roles. 3. Assign Ownership It is virtually impossible to keep process documentation simple and meaningful if employees who are far removed from the activity itself create it. It is impossible to keep documentation up-to-date when responsibility for the document is not clearly understood.Key to the Tutor methodology, therefore, is the concept of ownership. Each document has a single owner, who is responsible for ensuring that the document is necessary and that it reflects actual practice. The owner must be a person who is knowledgeable about the activity and who has the authority to build consensus among the persons who participate in the activity as well as the authority to define or change the way an activity is performed. The owner must be an advocate of the performers and negotiate, not dictate practices.In the Tutor environment, a document's owner is the only person with the authority to approve an update to that document. 4. Centralize Publishing Although it is tempting (especially in a networked environment and with document management software solutions) to decentralize the control of all documents -- with each owner updating and distributing his own -- Tutor promotes centralized publishing by assigning the Document Administrator (gate keeper) to manage the updates and distribution of the procedures library. 5. Establish a Document Maintenance Process Up Front (and stick to it) Everyone in your organization should know they are invited to suggest changes to procedures and should understand exactly what steps to take to do so. Tutor provides a set of procedures to help your company set up a healthy document control system. There are many document management products available to automate some of the document change and maintenance steps. Depending on the size of your organization, a simple document management system can reduce the effort it takes to track and distribute document changes and updates. Whether your company decides to store the written policies and procedures on a file server or in a database, the essential tasks for maintaining documents are the same, though some tasks are automated. 6. Document Critical Activities Only The best way to keep your documentation simple is to reduce the number of process documents to a bare minimum and to include in those documents only as much detail as is absolutely necessary. The first step to reducing process documentation is to document only those activities that are deemed critical. Not all activities require documentation. In fact, some critical activities cannot and should not be standardized. Others may be sufficiently documented with an instruction or a checklist and may not require a procedure. A document should only be created when it enhances the performance of the employee performing the activity. If it does not help the employee, then there is no reason to maintain the document. Activities that represent little risk (such as project status), activities that cannot be defined in terms of specific tasks (such as product research), and activities that can be performed in a variety of ways (such as advertising) often do not require documentation. Sometimes, an activity will evolve to the point where documentation is necessary. For example, an activity performed by single employee may be straightforward and uncomplicated -- that is, until the activity is performed by multiple employees. Sometimes, it is the interaction between co-workers that necessitates documentation; sometimes, it is the complexity or the diversity of the activity.7. Document Actual Practices The only reason to maintain process documentation is to enhance the performance of the employee performing the activity. And documentation can only enhance performance if it reflects reality -- that is, current best practice. Documentation that reflects an unattainable ideal or outdated practices will end up on the shelf, unused and forgotten.Documenting actual practice means (1) auditing the activity to understand how the work is really performed, (2) identifying best practices with employees who are involved in the activity, (3) building consensus so that everyone agrees on a common method, and (4) recording that consensus.8. Minimize Documentation One way to keep it simple is to document at the highest level possible. That is, include in your documents only as much detail as is absolutely necessary.When writing a document, you should ask yourself, What is the purpose of this document? That is, what problem will it solve?By focusing on this question, you can target the critical information.• What questions are the end users likely to have?• What level of detail is required?• Is any of this information extraneous to the document's purpose? Short, concise documents are user friendly and they are easier to keep up to date. 9. Support Continuous Improvement Employees who perform an activity are often in the best position to identify improvements to the process. In other words, continuous improvement is a natural byproduct of the work itself -- but only if the improvements are communicated to all employees who are involved in the process, and only if there is consensus among those employees.Traditionally, process documentation has been used to dictate performance, to limit employees' actions. In the Tutor environment, process documents are used to communicate improvements identified by employees. How does this work? The Tutor methodology requires a process document to reflect actual practice, so the owner of a document must routinely audit its content -- does the document match what the employees are doing? If it doesn't, the owner has the responsibility to evaluate the process, to build consensus among the employees, to identify "best practices," and to communicate these improvements via a document update. Continuous improvement can also be an outgrowth of corrective action -- but only if the solutions to problems are communicated effectively. The goal should be to solve a problem once and only once, which means not only identifying the solution, but ensuring that the solution becomes part of the process. The Tutor system provides the method through which improvements and solutions are documented and communicated to all affected employees in a cost-effective, timely manner; it ensures that improvements are not lost or confined to a single employee. 10. Keep it Simple Process documents don't have to be complex and unfriendly. In fact, the simpler the format and organization, the more likely the documents will be used. And the simpler the method of maintenance, the more likely the documents will be kept up-to-date. Keep it simply by:• Minimizing skills and training required• Following the established Tutor document format and layout• Avoiding technology just for technology's sake No other rule has as major an impact on the success of your internal documentation as -- keep it simple.

  • Domain masking (and simple page links)

    - by Halik
    How do you set up the domain (Im using godaddy) to mask the server url but to append the sub-page link. Im thinking something like the wikipedia en.wikipedia.org/wiki/something (or, if it would require httpd.conf access, setting it to append the default subpage link eg. '?page_id=2') Currently I can set up the domain to either be masked completely without showing any sub-page links or to simply redirect my domain to my web server.

  • Separating a "wad of stuff" utility project into individual components with "optional" dependencies

    - by romkyns
    Over the years of using C#/.NET for a bunch of in-house projects, we've had one library grow organically into one huge wad of stuff. It's called "Util", and I'm sure many of you have seen one of these beasts in your careers. Many parts of this library are very much standalone, and could be split up into separate projects (which we'd like to open-source). But there is one major problem that needs to be solved before these can be released as separate libraries. Basically, there are lots and lots of cases of what I might call "optional dependencies" between these libraries. To explain this better, consider some of the modules that are good candidates to become stand-alone libraries. CommandLineParser is for parsing command lines. XmlClassify is for serializing classes to XML. PostBuildCheck performs checks on the compiled assembly and reports a compilation error if they fail. ConsoleColoredString is a library for colored string literals. Lingo is for translating user interfaces. Each of those libraries can be used completely stand-alone, but if they are used together then there are useful extra features to be had. For example, both CommandLineParser and XmlClassify expose post-build checking functionality, which requires PostBuildCheck. Similarly, the CommandLineParser allows option documentation to be provided using the colored string literals, requiring ConsoleColoredString, and it supports translatable documentation via Lingo. So the key distinction is that these are optional features. One can use a command line parser with plain, uncolored strings, without translating the documentation or performing any post-build checks. Or one could make the documentation translatable but still uncolored. Or both colored and translatable. Etc. Looking through this "Util" library, I see that almost all potentially separable libraries have such optional features that tie them to other libraries. If I were to actually require those libraries as dependencies then this wad of stuff isn't really untangled at all: you'd still basically require all the libraries if you want to use just one. Are there any established approaches to managing such optional dependencies in .NET?

  • Design patterns to avoiding breaking the SRP while performing heavy data logging

    - by Kazark
    A class that performs both computations and data logging seems to have at least two responsibilities. Given a system for which the specifications require heavy data logging, what kind of design patterns or architectural patterns can be used to avoid bloating all the classes with logging calls every time they compute something? The decorator pattern be used (e.g. Interpolator decorated to LoggingInterpolator), but it seems that would result in a situation hardly more desirable in which almost every major class would need to be decorated with logging.

  • Stitch scanned images using CLI

    - by Adam Matan
    I have scanned a newspaper article which was larger than the scanner glass. Each page was scanned twice: the top and the bottom parts, where the middle part appeared in both images. Is there a way to quickly match and stitch these scanned images, preferably using CLI? The panorama stitching tools I know require lengthy configuration, which is mostly irrelevant: lens size, focus, angle etc. Hugin has a solution for this issue, but it isn't practical for batch jobs.

  • Javascript Implementation Patterns for Server-side MVC Websites

    - by tmo256
    I'm looking for information on common patterns for initializing and executing Javascript page by page in a "traditional" server-side MVC website architecture. A few months ago, my development team began, but abandoned, a major re-architecture of our company's primary web app, including a full front-end redesign. In the process, there was some debate about the architecture of the Javascript in the current version of the site, and whether it fit into a clear, modern design pattern. Now I've returned to the process of overhauling the front end of this and several other MVC websites (Ruby on Rails and MVC.net) to implement a responsive framework (Bootstrap), and in the process will again need to review then revamp and update a lot of Javascript. These web applications are NOT single-page Javascript applications (in fact, we are ripping out a lot of Ajax) or designed to require a Javascript MVC pattern; these apps are basically brochure, catalog and administrative sites that follow a server-side MVC pattern. The vast majority of the Javascript required is behavioral, pre-built plugins (JQuery and Bootstrap, et al) that execute on specific DOM nodes. I'm going to give a very brief (as brief as I can be) run-down of the current architecture only in order to illustrate the scope and type of paradigm I'm talking about. Hopefully, it will help you understand the nature of the patterns I'm looking for, but I'm not looking for commentary on the specifics of this code. What I've done in the past is relatively straight-forward and easy to maintain, but, as mentioned above, some of the other developers don't like the current architecture. Currently, on document ready, I execute whatever global Javascript needs to occur on every page, and then call a page-specific init function to initialize node-specific functionality, retrieving the init method from a JS object. On each page load, something like this will happen: $(document).ready(function(){ $('header').menuAction(); App.pages.executePage('home','show'); //dynamic from framework request object }); And the main App javascript is like App = { usefulGlobalVar: 0, pages: { executePage: function(action, controller) { // if exists, App.pages[action][controller].init() }, home: { show: { init: function() { $('#tabs').tabs(); //et. al }, normalizeName: function() { // dom-specific utility function that // doesn't require a full-blown component/class/module } }, edit: ... }, user_profile: ... } } Any common features and functionality requiring modularization or compotentizing is done as needed with prototyping. For common implementation of plugins, I often extend JQuery, so I can easily initialize a plugin with the same options throughout the site. For example, $('[data-tabs]').myTabs() with this code in a utility javascript file: (function($) { $.fn.myTabs = function() { this.tabs( { //...common options }); }; }) Pointers to articles, books or other discussions would be most welcome. Again, I am looking for a site-wide implementation pattern, NOT a JS MVC framework or general how-tos on creating JS classes or components. Thanks for your help!

  • How To Disable Individual Plug-ins in Google Chrome

    - by The Geek
    Have you ever wondered how to disable useless or insecure browser plug-ins in Google Chrome? Here’s the lowdown on how to get rid of Java, Acrobat, Silverlight, and the rest of the plugins you probably want to get rid of. Disabling Plugins in Google Chrome If you head to about:plugins in your address bar, you’ll probably see a list of plugins, but won’t be able to disable them yet. What you’ll need to do is switch over to the Dev channel of Chrome, which gives you access to all the latest features—though you might be warned that sometimes the dev channel might be less stable than the release or beta channels. Ready to proceed? Head to the Dev Channel page, and then click the link to run the installer. You’ll be prompted to restart Chrome when you’re done. Note that Mac and Windows users can both run an installer to switch. Linux users will have to install a package. Note: Once you’ve switched to the Dev channel, you can’t really switch to the stable channel. You’ll have to uninstall Chrome and then reinstall the regular version. Now that you’ve switched to the dev channel and restarted your browser, head to about:plugins in the address bar, and then just disable each plugin you really don’t need. Plugins you can generally live without?  Java, Acrobat, Microsoft Office, Windows Presentation Foundation, Silverlight. These will be on a case-by-case basis, of course, but the vast majority of large websites don’t require any of those. When it comes right down to it, the only plugin that most people require is Flash… and leave the “Default Plug-in” alone too. Special thanks to @jordanconway for pointing out the solution.

  • Securing WebSocket applications on Glassfish

    - by Pavel Bucek
    Today we are going to cover deploying secured WebSocket applications on Glassfish and access to these services using WebSocket Client API. WebSocket server application setup Our server endpoint might look as simple as this: @ServerEndpoint("/echo") public class EchoEndpoint { @OnMessage   public String echo(String message) {     return message + " (from your server)";   } } Everything else must be configured on container level. We can start with enabling SSL, which will require web.xml to be added to your project. For starters, it might look as following: <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee">   <security-constraint>     <web-resource-collection>       <web-resource-name>Protected resource</web-resource-name>       <url-pattern>/*</url-pattern>       <http-method>GET</http-method>     </web-resource-collection>     <!-- https -->     <user-data-constraint>       <transport-guarantee>CONFIDENTIAL</transport-guarantee>     </user-data-constraint>   </security-constraint> </web-app> This is minimal web.xml for this task - web-resource-collection just defines URL pattern and HTTP method(s) we want to put a constraint on and user-data-constraint defines that constraint, which is in our case transport-guarantee. More information about these properties and security settings for web application can be found in Oracle Java EE 7 Tutorial. I have some simple webpage attached as well, so I can test my endpoint right away. You can find it (along with complete project) in Tyrus workspace: [webpage] [whole project]. After deploying this application to Glassfish Application Server, you should be able to hit it using your favorite browser. URL where my application resides is https://localhost:8181/sample-echo-https/ (may be different, depends on other configuration). My browser warns me about untrusted certificate (I use what freshly built Glassfish provides - self signed certificates) and after adding an exception for this site, I can see my webpage and I am able to securely connect to wss://localhost:8181/sample-echo-https/echo. WebSocket client Already mentioned demo application also contains test client, but execution of this is skipped for normal build. Reason for this is that Glassfish uses these self-signed "random" untrusted certificates and you are (in most cases) not able to connect to these services without any additional settings. Creating test WebSocket client is actually quite similar to server side, only difference is that you have to somewhere create client container and invoke connect with some additional info. Java API for WebSocket allows you to use annotated and programmatic way to construct endpoints. Server side shows the annotated case, so let's see how the programmatic approach will look. final WebSocketContainer client = ContainerProvider.getWebSocketContainer(); client.connectToServer(new Endpoint() {   @Override   public void onOpen(Session session, EndpointConfig EndpointConfig) {     try {       // register message handler - will just print out the       // received message on standard output.       session.addMessageHandler(new MessageHandler.Whole<String>() {       @Override         public void onMessage(String message) {          System.out.println("### Received: " + message);         }       });       // send a message       session.getBasicRemote().sendText("Do or do not, there is no try.");     } catch (IOException e) {       // do nothing     }   } }, ClientEndpointConfig.Builder.create().build(),    URI.create("wss://localhost:8181/sample-echo-https/echo")); This client should work with some secured endpoint with valid certificated signed by some trusted certificate authority (you can try that with wss://echo.websocket.org). Accessing our Glassfish instance will require some additional settings. You can tell Java which certificated you trust by adding -Djavax.net.ssl.trustStore property (and few others in case you are using linked sample). Complete command line when you are testing your service might need to look somewhat like: mvn clean test -Djavax.net.ssl.trustStore=$AS_MAIN/domains/domain1/config/cacerts.jks\ -Djavax.net.ssl.trustStorePassword=changeit -Dtyrus.test.host=localhost\ -DskipTests=false Where AS_MAIN points to your Glassfish instance. Note: you might need to setup keyStore and trustStore per client instead of per JVM; there is a way how to do it, but it is Tyrus proprietary feature: http://tyrus.java.net/documentation/1.2.1/user-guide.html#d0e1128. And that's it! Now nobody is able to "hear" what you are sending to or receiving from your WebSocket endpoint. There is always room for improvement, so the next step you might want to take is introduce some authentication mechanism (like HTTP Basic or Digest). This topic is more about container configuration so I'm not going to go into details, but there is one thing worth mentioning: to access services which require authorization, you might need to put this additional information to HTTP headers of first (Upgrade) request (there is not (yet) any direct support even for these fundamental mechanisms, user need to register Configurator and add headers in beforeRequest method invocation). I filed related feature request as TYRUS-228; feel free to comment/vote if you need this functionality.

  • What are the advantages of the delegate pattern over the observer pattern?

    - by JoJo
    In the delegate pattern, only one object can directly listen to another object's events. In the observer pattern, any number of objects can listen to a particular object's events. When designing a class that needs to notify other object(s) of events, why would you ever use the delegate pattern over the observer pattern? I see the observer pattern as more flexible. You may only have one observer now, but a future design may require multiple observers.

  • Skyrim Creation Kit with Xbox 360

    - by funseiki
    I posted this on stackoverflow but was advised to post here (here is a link to the stackoverflow question). I'm hoping for constructive feedback on its plausibility. Update on progress: It looks like there are ways to stuff files back onto the console (horizon, modio, xplorer360, etc) and they do require some form of signing. As of now, though, I've had no luck. I was hoping I could get away with just placing the ".esp" into the directory containing marketplace downloads for Skyrim, along with the signed ".bsa" file (basically a zipped up file containing any extra content the .esp will need to refer that doesn't exist in the basic game). This doesn't work, at least not in the ways I've tried, so next I'm going to try install the entire game to my flash drive (if possible) and attempt to traverse through the game's directory (this is probably unlikely). If anyone else has suggestions or luck or wants more detail on my failures comment/answer away. Here is the question: I'm thinking about buying the PC version of Skyrim to get the Creation Kit (I already own a copy for the Xbox). I have read the faq and scoured plenty of forums to see if there was some way to mod Skyrim for a console (Xbox 360, in particular), but they are generally coming up negative. I realize the CreationKit is on the PC, but I was wondering if there was a way to set up the '.esp' (hopefully I'm interpreting this correctly) files to be placed on the Xbox 360 file system in a similar manner to how game add-ons are downloaded from the Xbox Live Marketplace. I believe it is possible to transfer saves between the console and the PC (e.g. google: 'skyrim mod xbox360'), but these are referencing items that already exist in the game (e.g. a console command for maximum carry weight does not require reference to new animations or models). It would probably be easier if one could navigate through the xbox's file system to see where the games' files are placed, but with the current setup, the file system is abstracted away. Any help or insight on the matter would be much appreciated. I would love to work on a project that would make it possible to let console gamers experience and enjoy all the great mods available to the PC community.
