  • In what way I can implement packet filtering function in C++/C#?

    - by Network study
    Background: I am going to design a firewall-like application (with GUI) which will include several functions such as Packet sniffing and packet filtering. Both of the functions should be implemented to support different protocol levels including application, transport, network and link layer. I only know a little in C#.Net programming to perform the IP packet sniffing. It is also known that packet filtering requires the techniques in WFP or LSP and packet sniffing in application requires dll hooking. Questions: I am not sure which programming language(either C++ or C#) would be suitable for designing such an application described above. If I want to implement the packet filtering function, any libraries will be needed? edit01: Someone suggest that winDivert would be helpful, is it true?

  • The Ubuntu App Showdown -Specific software

    - by Stefanie
    I would like to participate the contest but I'm programming very specific scientific tools for the work in a molecular biological lab. I know that I won't win with such an app but it's a nice possibility to get into Qickly and Ubuntu Apps since I'm only programming for Windows at the moment. My question is, whether I have a possibility to explain what my software is doing and for what it is good in the lab. Also I have to provide some test data, that the jury can try it out. Is this possible and how I can submit those additional information?

  • What should I learn next?

    - by Krysten
    I am a CS major. I've taken 2 courses in C (Intro to C and CS1) and 1 introductory course to OOP with Java. I really like Java and feel that I have a firm understanding of OOP concepts. I am really interested in web development and would like to learn a programming language that can be used to build dynamic web applications. My question is what language should I learn? I've narrowed it down to python or ruby. Also, I want to learn a programming language that will help me get a job upon graduating. So essentially, I will use this particular language to build applications that will help me get a job in the future.

  • Should Equality be commutative within a Class Hierachy?

    - by vossad01
    It is easy to define the Equals operation in ways that are not commutative. When providing equality against other types, there are obviously situations (in most languages) were equality not being commutative is unavoidable. However, within one's own inheritance hierarchy where the root base class defines an equality member, a programmer has more control. Thus you can create situations where (A = B) ? (B = A), where A and B both derive from base class T Substituting the = with the appropriate variation for a given language. (.Equals(_), ==, etc.) That seems wrong to me, however, I recognize I may be biased by background in Mathematics. I have not been in programming long enough to know what is standard/accepted/preferred practice when programming. Do most programmers just accept .Equals(_)may not be commutative and code defensibly. Do they expect commutativity and get annoyed if it is not. In short, when working in a class hierarchy, should effort me made to ensure Equality is commutative?

  • Am I unhireable?

    - by DrSammyD
    I've received my B.S. in Software Engineering in August 2010 and I've been looking for a job since. I've gotten two interviews since that went up to the technical phone interview and then they were no longer interested. One of the recruiters mentioned to me that they thought my fundamentals weren't strong enough. What do I need to brush up on in order to get past the technical phone interview. My language of most experience is C#. I know Object Oriented Programming. I know what the difference between an interface and an abstract class is. I've applied to positions from game programming to WPF/Silverlight. I have a portfolio website www.samarmstrong.me. It also has my resume on there. I never had real internship. Am I unhireable?

  • Connection make b/w iphone to windows pc-rajay [on hold]

    - by Rajay
    I Need to create connection between ios to windows by using socket programming in ios. I'm trying to to use an application to communicate with Windows via sockets. At the minimum, I'm trying to at least figure out how I can create a connection from the iPhone (maybe using the iPhone to ping the Windows machine?) I'm not really clear on where I need to start. I'm pretty new to iOS development in general, and brand new to socket/network programming. I've tried several tutorials that haven't gotten me far. My goal is: Connect to a server via sockets (the server will be a Windows machine with a service waiting for incoming connections from the iPhone) If possible, I would like to write/build the client piece first, but I have been lost thus far. Hopefully the nice folks in the SO community can lend a hand and point me in the right direction.

  • Can you run OpenGL 2.0 on modern machines?

    - by thePalindrome
    I'm looking to get into 3d with OpenGL, using SDL to help with other stuff. I found plenty of good tutorials (lazyfoo is a big one), but "Learning Modern 3d Graphics Programming" uses a newer version of openGL that I'm not able to run! I opened up OpenGL extensions viewer, and I can only run OpenGL 2.0, whereas most tutorials are in higher versions. I ask this because I've heard that just about everything in 2.* got depreciated in the newer versions, so I'm worried that my code might not work. I'm looking at a few other tutorials, but I'm so used to SDL that those just confuse me... So should I bother trying to do graphics programming now, or should I just wait until I can upgrade my computer?

  • C# .NET 4.0 interactive course?

    - by Kanyhalos
    I would like to learn C# programming. I already studied it for several weeks and wrote some minor programs with VS2010, and I'm not completely newbie at programming because I worked on STALKER - Shadow of Chernobyl as scripter, but it was LUA. I want to become a real programmer. I think C# is a decent way to start with. I already learned about the most commonly used resource sites and got some nice eBooks as well, but unfortunately I don't have time to sit down in front my computer all the time, so my progress is pretty slow. I would like to ask that if someone can recommend me some decent interactive online courses to make my learning progress faster. I know about the "joe grip" course but I don't know if it's worth $39 also it's only for .NET 1.x and 2.0 while I'd like to learn 4.0 so I have no idea what should I do.

  • Any tips/tricks/resources on actually TEACHING a class on OOP? [closed]

    - by Sempus
    I may slowly be getting into teaching an Object-Orientated Programming class at my school in a year or two. I just graduated and work at my school as an Application Programmer. I'd first start off as a TA/grader and then slowly move into the Professor role. The class would be in Java. I always see resources on this fine site about HOW to program, but does anyone know any tips/tricks/resources on how to TEACH a programming class? It would be full of all different skills levels(but still semi-technical) so it would have to be a little more understandable than if it was just CS kids.

  • Ideas for how to structure a developer class/course? [on hold]

    - by Andy
    Let's say I need to teach a 3-8 week course in programming/development at a technical school (no kids) (regardless of language or technology and the target audience is beginners). I need ideas to make it a awesome class where I : Maximize the students learning and experience Make sure they don't fall a sleep Engage the students Make it exciting! I can always do traditional lecture+exercises and repeat this pattern over and over, but I think this is to old-school. Things I have considered to add to the course are: - Require pair programming - Code-review together with the students I would like suggestions on how to make a modern training class state really awesome?

  • What is your personal learning process? [closed]

    - by yadvent
    I just wanted to say hello and ask a few simple questions. I have recently dove into programming with c# and have been curious what everyone else's experiences have been with when learning and starting out. What are some things that you can say that really have made a difference in your understanding and usages of any particular language? I lurk several forums but for some reason have always just kept to myself, and I've realized today that I'm not fully utilizing my resources when it comes to interacting with the community. With that being said, I realize that everyone that is interested in programming inherently is a natural problem solver and would like also to ask you to share your process of learning. Are you the type to have a short term project to tackle a general set of problems you're likely to encounter? Or are you a type of programmer that practices by zeroing in on a specific few problems you would like to solve? Any reply will be greatly appreciated Thank you :)

  • Looking for a previous post about skillsets for an embedded/firmware engineer. Can't find it anymore [closed]

    - by Sandiego
    I remember reading a post inquiring the basic/advanced skills required for embedded engineer works. The top comment divides the answer into two parts, the basic level/design level ,not purely coding(something like this...). Then another level : writing application(all about programming). For each level/category, the top comment talks about the necessary skills/knowledge/college courses(for me at least) . While I was searching for this post as I was trying to read it again, I found similar questions, but these are not the one I saw: http://stackoverflow.com/questions/1091931/what-skill-set-should-a-low-level-programmer-possess http://stackoverflow.com/questions/45247/how-do-i-get-started-in-embedded-programming http://electronics.stackexchange.com/questions/3343/how-to-become-an-embedded-software-developer Has anyone seen the post I'm talking about? This is a repost from Stackoverflow where I was told that this question is off-topic. So..please help guys

  • Recommended Books for OpenGL [closed]

    - by TheBlueCat
    I'm fairly new to OpenGL and I'm have been researching any books that would be beneficial, I've had suggested to me (I've finished reading the OpenGL Book online): Real Time Rendering GPU Gems 3 OpenGL Super Bible Does anyone know any other books that they've found useful in the past, even if it covers higher level algorithms. Also, can anyone suggest an IDE/Text Editor for Linux? I'm using Komodo and it's super buggy, I just booted into Windows today and tried Visual Studio and loved it, is their anything similar for Linux? Although, the books I've been reading are saying to not use IDEs, partly because of the reliance you place onto them, per se. I use Eclipse a lot for my Java programming, can I use C and OpenGL with that? Lastly, do you think it would be more beneficial staying on Windows and programming in C/OpenGL on their, I do like Linux, but I found Visual Studio to be pretty good in some aspects?

  • Please recommend me intermediate-to-advanced Python books to buy.

    - by anonnoir
    I'm in the final year, final semester of my law degree, and will be graduating very soon. (April, to be specific.) But before I begin practice, I plan to take 2 two months off, purely for serious programming study. So I'm currently looking for some Python-related books, gauged intermediate to advanced, which are interesting (because of the subject matter itself) and possibly useful to my future line of work. I've identified 2 possible purchases at the moment: Natural Language Processing with Python. The law deals mostly with words, and I've quite a number of ideas as to where I might go with NLP. Data extraction, summaries, client management systems linked with document templates, etc. Programming Collective Intelligence. This book fascinates me, because I've always liked the idea of machine learning (and I'm currently studying it by the side too, for fun). I'd like to build/play around with Web 2.0 applications; and who knows if I can apply some of the things I learn to my legal work. (E.g. Playground experiments to determine how and under what circumstances judges might be biased, by forcing algorithms to pore through judgments and calculate similarities, etc.) Please feel free to criticize my current choices, but do at least offer or recommend other books that I should read in their place. My budget can deal with 4 books, max. These books will be used heavily throughout the 2 months; I will be reading them back to back, absorbing the explanations given, and hacking away at their code. Also, the books themselves should satisfy 2 main criteria: Application. The book must teach how to solve problems. I like reading theory, but I want to build things and solve problems first. Even playful applications are fine, because games and experiments always have real-world applications sooner or later. Readability. I like reading technical books, no matter how difficult they are. I enjoy the effort and the feeling that you're learning something. But the book shouldn't contain code or explanations that are too cryptic or erratic. Even if it's difficult, the book's content should be accessible with focused reading. Note: I realize that I am somewhat of a beginner to the whole programming thing, so please don't put me down. But from experience, I think it's better to aim up and leave my comfort zone when learning new things, rather than to just remain stagnant the way I am. (At least the difficulty gives me focus: i.e. if a programmer can be that good, perhaps if I sustain my own efforts I too can be as good as him someday.) If anything, I'm also a very determined person, so two months of day-to-night intensive programming study with nothing else on my mind should, I think, give me a bit of a fighting chance to push my programming skills to a much higher level.

  • Will rel=canonical break site: queries ?

    - by Justin Grant
    Our company publishes our software product's documentation using a custom-built content management system using a dynamic URL namespace like this: http://ourproduct.com/documentation/version/pageid Where "version" is the version number to which the documentation applies, and "pageid" is a unique string which identifies that page in our back-end content management system. For example, if content (e.g. a page about configuration best practices) is unchanged from version 3.0 and 4.0 of our product, it'd be reachable by two different URLs: http://ourproduct.com/documentation/3.0/configuration-best-practices http://ourproduct.com/documentation/4.0/configuration-best-practices This URL scheme allows us to scope Google search results to see only documentaiton for a particular product version, like this: configuration site:ourproduct.com/documentation/4.0 But when the user is searching across all versions, we don't want Google to arbitrarily choose one of the URLs to show in results. Instead, we always want the latest version to show up. Hence our planned use of rel=canonical so we can proscriptively tell Google which URL we want to show up if multiple versions are being searched. (Users who do oddball things like searching 2 versions but not all of them are a corner case, so we don't care which version(s) show up in that case-- the primary use-cases we care about is searching one version or searching all versions) But what will happen to scoped searches if we do this? If my rel=canonical URL points to version 4.0, but my search is scoped to 3.0, will Google return a result? Even if you don't know the answer offhand, do you know a site which uses rel=canonical to redirect across folders in a URL namespace. If so, I could run a few Google searches and figure out the answer.

  • super light software development process

    - by Walty
    hi, For the development process I have involved so far, most have teams of SINGLE member, or occasionally two. We used python + django for the major development, the development process is actually very fast, and we do have code reviews, design pattern discussions, and constant refactoring. Though team size is small, I do think there are some development processes / best practices that could be enforced. For example, using svn would be definitely better than regular copy backup. I did read some articles & books about Agile, XP & continuous integration, I think they are nice, but still too heavy for this case (team of 1 or 2, and fast coding). For example, IMHO, with nice design pattern, and iterative development + refactoring, the TDD MIGHT be an overkill, or at least the overhead does not out-weight the advantages. And so is the pair programming. The automated testing is a nice idea, but it seems not technically feasible for every project. our current practices are: svn + milestone + code review I wonder if there are development processes / best practices specifically targeted on such super light teams? thanks.

This post attempts to highlight some of the best practices along with dos & don’ts that our practice has accumulated over the years in the identity & access management space in general, and also in the context of R2, in particular. Best Practices The following section illustrates the leading practices in “How” to plan, implement and sustain a successful OIM deployment, based on our collective experience. Planning is critical, but often overlooked A common approach to planning an IAM program that we identify with our clients is the three step process involving a current state assessment, a future state roadmap and an executable strategy to get there. It is extremely beneficial for clients to assess their current IAM state, perform gap analysis, document the recommended controls to address the gaps, align future state roadmap to business initiatives and get buy in from all stakeholders involved to improve the chances of success. When designing an enterprise-wide solution, the scalability of the technology must accommodate the future growth of the enterprise and the projected identity transactions over several years. Aligning the implementation schedule of OIM to related information technology projects increases the chances of success. As a baseline, it is recommended to match hardware specifications to the sizing guide for R2 published by Oracle. Adherence to this will help ensure that the hardware used to support OIM will not become a bottleneck as the adoption of new services increases. If your Organization has numerous connected applications that rely on reconciliation to synchronize the access data into OIM, consider hosting dedicated instances to handle reconciliation. Finally, ensure the use of clustered environment for development and have at least three total environments to help facilitate a controlled migration to production. If your Organization is planning to implement role based access control, we recommend performing a role mining exercise and consolidate your enterprise roles to keep them manageable. In addition, many Organizations have multiple approval flows to control access to critical roles, applications and entitlements. If your Organization falls into this category, we highly recommend that you limit the number of approval workflows to a small set. Most Organizations have operations managed across data centers with backend database synchronization, if your Organization falls into this category, ensure that the overall latency between the datacenters when replicating the databases is less than ten milliseconds to ensure that there are no front office performance impacts. Ingredients for a successful implementation During the development phase of your project, there are a number of guidelines that can be followed to help increase the chances for success. Most implementations cannot be completed without the use of customizations. If your implementation requires this, it’s a good practice to perform code reviews to help ensure quality and reduce code bottlenecks related to performance. We have observed at our clients that the development process works best when team members adhere to coding leading practices. Plan for time to correct coding defects and ensure developers are empowered to report their own bugs for maximum transparency. Many organizations struggle with defining a consistent approach to managing logs. This is particularly important due to the amount of information that can be logged by OIM. We recommend Oracle Diagnostics Logging (ODL) as an alternative to be used for logging. ODL allows log files to be formatted in XML for easy parsing and does not require a server restart when the log levels are changed during troubleshooting. Testing is a vital part of any large project, and an OIM R2 implementation is no exception. We suggest that at least one lower environment should use production-like data and connectors. Configurations should match as closely as possible. For example, use secure channels between OIM and target platforms in pre-production environments to test the configurations, the migration processes of certificates, and the additional overhead that encryption could impose. Finally, we ask our clients to perform database backups regularly and before any major change event, such as a patch or migration between environments. In the lowest environments, we recommend to have at least a weekly backup in order to prevent significant loss of time and effort. Similarly, if your organization is using virtual machines for one or more of the environments, it is recommended to take frequent snapshots so that rollbacks can occur in the event of improper configuration. Operate & sustain the solution to derive maximum benefits When migrating OIM R2 to production, it is important to perform certain activities that will help achieve a smoother transition. At our clients, we have seen that splitting the OIM tables into their own tablespaces by categories (physical tables, indexes, etc.) can help manage database growth effectively. If we notice that a client hasn’t enabled the Oracle-recommended indexing in the applicable database, we strongly suggest doing so to improve performance. Additionally, we work with our clients to make sure that the audit level is set to fit the organization’s auditing needs and sometimes even allocate UPA tables and indexes into their own table-space for better maintenance. Finally, many of our clients have set up schedules for reconciliation tables to be archived at regular intervals in order to keep the size of the database(s) reasonable and result in optimal database performance. For our clients that anticipate availability issues with target applications, we strongly encourage the use of the offline provisioning capabilities of OIM R2. This reduces the provisioning process for a given target application dependency on target availability and help avoid broken workflows. To account for this and other abnormalities, we also advocate that OIM’s monitoring controls be configured to alert administrators on any abnormal situations. Within OIM R2, we have begun advising our clients to utilize the ‘profile’ feature to encapsulate multiple commonly requested accounts, roles, and/or entitlements into a single item. By setting up a number of profiles that can be searched for and used, users will spend less time performing the same exact steps for common tasks. We advise our clients to follow the Oracle recommended guides for database and application server tuning which provides a good baseline configuration. It offers guidance on database connection pools, connection timeouts, user interface threads and proper handling of adapters/plug-ins. All of these can be important configurations that will allow faster provisioning and web page response times. Many of our clients have begun to recognize the value of data mining and a remediation process during the initial phases of an implementation (to help ensure high quality data gets loaded) and beyond (to support ongoing maintenance and business-as-usual processes). A successful program always begins with identifying the data elements and assigning a classification level based on criticality, risk, and availability. It should finish by following through with a remediation process. Dos & Don’ts Here are the most common dos and don'ts that we socialize with our clients, derived from our experience implementing the solution. Dos Don’ts Scope the project into phases with realistic goals. Look for quick wins to show success and value to the stake holders. Avoid “boiling the ocean” and trying to integrate all enterprise applications in the first phase. Establish an enterprise ID (universal unique ID across the enterprise) earlier in the program. Avoid major UI customizations that require code changes. Have a plan in place to patch during the project, which helps alleviate any major issues or roadblocks (product and database). Avoid publishing all the target entitlements if you don't anticipate their usage during access request. Assess your current state and prepare a roadmap to address your operations, tactical and strategic goals, align it with your business priorities. Avoid integrating non-production environments with your production target systems. Defer complex integrations to the later phases and take advantage of lessons learned from previous phases Avoid creating multiple accounts for the same user on the same system, if there is an opportunity to do so. Have an identity and access data quality initiative built into your plan to identify and remediate data related issues early on. Avoid creating complex approval workflows that would negative impact productivity and SLAs. Identify the owner of the identity systems with fair IdM knowledge and empower them with authority to make product related decisions. This will help ensure overcome any design hurdles. Avoid creating complex designs that are not sustainable long term and would need major overhaul during upgrades. Shadow your internal or external consulting resources during the implementation to build the necessary product skills needed to operate and sustain the solution. Avoid treating IAM as a point solution and have appropriate level of communication and training plan for the IT and business users alike. Conclusion In our experience, Identity programs will struggle with scope, proper resourcing, and more. We suggest that companies consider the suggestions discussed in this post and leverage them to help enable their identity and access program. This concludes PwC blog series on R2 for the month and we sincerely hope that the information we have shared thus far has been beneficial.

  • Who are Alice and Bob? [closed]

    - by froadie
    I did search for this on SO, as I assumed someone must have asked it before, similar to the Foo-Bar questions. But I haven't found it, so I'm asking it myself. Is it just me, or are the names Alice and Bob used often in connection to programming, emailing, encoding...? Where did these names come from? What is their relation to computers/programming?

  • What are some good resources for learning C beyond K&R

    - by Roland
    Hi, I'm currently reaching the end of working through the K&R book "The C Programming Language", and I'm looking for things to read next. Any recommendations of: blogs more detailed / advanced books (I've already stuck Advanced Programming in a Unix Environment on my Safari bookshelf) open source code (beginner-friendly and with good C idioms or style) to read up on next would be gratefully appreciated. To be specific, I'm most interested in things relevant to a *nix environment rather than Windows. Cheers, Roland
