• What .NET objects should I use to create a cookie based session in MVC?

  - by makerofthings7

  I'm writing a custom password reset application that uses a validation technique that doesn't fit cleanly with ASP.NET Membership Provider's challenge questions. Namely I need to invoke a workflow and collect information from the end user (backup phone number, email address) after the user logs in using a custom form. The only way I know to create a cookie-based session (without too much "innovation" on my part) is to use WIF. What other standard objects can I use with ASP.NET MVC to create an authenticated session that works with non-windows user stores? Ideally I can store "role" or claim information in the session object such as "admin", "departmentXadmin", "normalUser", or "restrictedUser" The workflow would look like this: User logs in with username and password If the username and pw are correct a (stateless) cookie based session is created The user gets redirected to a HTML form that allows them to enter their backup phone number (for SMS dual factor), or validate it if already set. The user can then change their password using the form provided The "forgot password" would look like this User requests OTP code to be sent to the phone User logs in using username and OTP If the OTP is valid and not expired then create a cookie based session and redirect to a form that allows password reset Show password reset form, and process results.

  - by Bob Rhubart

  The Top 10 items shared via the OTN ArchBeat Facebook page for the week of October 7-13, 2012. OOW12: Oracle Business Process Management/Oracle ADF Integration Best Practices | Andrejus Baranovskis The Oracle OpenWorld presentations keep coming! Oracle ACE Director Andrejus Baranovskis shares the slides from "Oracle Business Process Management/Oracle ADF Integration Best Practices," co-presented with Danilo Schmiedel from Opitz Consulting. Oracle's Analytics, Engineered Systems, and Big Data Strategy | Mark Rittman Part 1 of 3 in Oracle ACE Director Mark Rittman's series on Oracle Exalytics, Oracle R Enterprise and Endeca.

Following the Thread in OSB | Antony Reynolds Antony Reynolds recently led an Oracle Service Bus POC in which his team needed to get high throughput from an OSB pipeline. "Imagine our surprise when, on stressing the system, we saw it lock up, with large numbers of blocked threads." He shares the details of the problem and the solution in this extensive technical post. WebCenter Sites Gadget Development Concepts Quickstart | John Brunswick What are Gadgets? "At their most basic level they can be thought of as lightweight portlets that run largely on the client side of an architecture," says John Brunswick. "Gadgets provide a cross-platform container to run reusable UI modules that generally expose dynamic information to an end user, allowing for some level of end user customization." Oracle Fusion Middleware Security: OAM and OIM 11g Academies Looking for technical how-to content covering Oracle Access Manager and Oracle Identity Manager? The people behind the Oracle Middleware Security blog have indexed relevant blog posts into what they call Academies.

• Security Audit Failures in Event Viewer Windows Server 2008R2

  - by Jacob

  When I am looking at the security tab of my event viewer on a Windows Server 2008 R2, I am showing a ton of Audit Failures with Event ID 4776. The computer attempted to validate the credentials for an account. Authentication Package: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0 Logon Account: randy Source Workstation: HPDB1 Error Code: 0xc0000064 I verified the account "randy" exist in my Active Directory. From my understanding, there has not been any recent password changes. Is there any way to get detailed information on this error? I am wondering what program is requesting this information. Also, is there any way to clear this error up? I was thinking about resetting the password and changing it back to the original.

• How can I tag sequences inside videos?

  - by Antoine

  For example, let's say I find a sequence in a WWDC session (Apple videos) that explains a technical point very well. I would like to be able to store the exact range in the video, tag it with keywords, and manage all that information. And when I want to share this information, I could simply export to a plain English sentence: "Have a look at the video named …". It would be great to be able to launch a video player for local videos and go straight to the beginning of the sequence.

• How to retain secondary hard drive mounts at reboot and keep shares?

  - by Tom

  I'm running Ubuntu 12.04. A second hard drive connected to this computer does not mount when the computer boots. Additionally, I have set up the drive to be shared but the share is not retained, the share is lost after each boot. My main system drive and a removable drive mount OK and shares remain between boots.

• How secure is a bluetooth keyboard against password sniffing?

  - by jhs

  In a situation where an admin will enter sensitive information into a keyboard (the root password), what is the risk that a bluetooth keyboard (ship by default with Mac systems these days) would put those passwords at risk? Another way of asking would be: what security and encryption protocols are used, if any, to establish a bluetooth connection between a keyboard and host system? Edit: Final Summary All answers are excellent. I accepted that which links to the most directly applicable information however I also encourage you to read Nathan Adams's response and discussion about security trade-offs.

• How can I reduce the amount of time it takes to fully regression test an application ready for release?

  - by DrLazer

  An app I work on is being developed with a modified version of scrum. If you are not familiar with scrum, it's just an alternative approach to a more traditional watefall model, where a series of features are worked on for a set amount of time known as a sprint. The app is written in C# and makes use of WPF. We use Visual C# 2010 Express edition as an IDE. If we work on a sprint and add in a few new features, but do not plan to release until a further sprint is complete, then regression testing is not an issue as such. We just test the new features and give the app a good once over. However, if a release is planned that our customers can download - a full regression test is factored in. In the past this wasn't a big deal, it took 3 or 4 days and the devs simply fix up any bugs found in the regression phase, but now, as the app is getting larger and larger and incorporating more and more features, the regression is spanning out for weeks. I am interested in any methods that people know of or use that can decrease this time. At the moment the only ideas I have are to either start writing Unit Tests, which I have never fully tried out in a commercial environment, or to research the possibilty of any UI Automation API's or tools that would allow me to write a program to perform a series of batch tests. I know literally nothing about the possibilities of UI automation so any information would be valuable. I don't know that much about Unit testing either, how complicated can the tests be? Is it possible to get Unit tests to use the UI? Are there any other methods I should consider? Thanks for reading, and for any advice in advance. Edit: Thanks for the information. Does anybody know of any alternatives to what has been mentioned so far (NUnit, RhinoMocks and CodedUI)?

• SSISDB Analysis Script on Gist

  - by Davide Mauri

  I've created two simple, yet very useful, script to extract some useful data to quickly monitor SSIS packages execution in SQL Server 2012 and after.get-ssis-execution-status  get-ssis-data-pumped-rows  I've started to use gist since it comes very handy, for this "quick'n'dirty" scripts and snippets, and you can find the above scripts and others (hopefully the number will increase over time...I plan to use gist to store all the code snippet I used to store in a dedicated folder on my machine) there.Now, back to the aforementioned scripts. The first one ("get-ssis-execution-status") returns a list of all executed and executing packages along with latest successful and running executions (so that on can have an idea of the expected run time)error messageswarning messages related to duplicate rows found in lookupsthe second one ("get-ssis-data-pumped-rows") returns information on DataFlows status. Here there's something interesting, IMHO. Nothing exceptional, let it be clear, but nonetheless useful: the script extract information on destinations and row sent to destinations right from the messages produced by the DataFlow component. This helps to quickly understand how many rows as been sent and where...without having to increase the logging level.Enjoy! PSI haven't tested it with SQL Server 2014, but AFAIK they should work without problems. Of course any feedback on this is welcome.

• Updating large icon in iTunes Connect

  - by Shaggy Frog

  Just wanted to see if I understand properly how/when one can change the "Large icon" for their iOS app in iTunes Connect. Questions are in bold below. To start, first the facts (as I gather) from version 6.6 of the iTC guide (March 2, 2011): The Large Icon is a "locked" piece of version information "You will only be permitted to edit Locked version information when your app is in an Editable state" The "Editable" states are: Prepare For Upload Waiting For Upload Waiting For Review Waiting For Export Compliance Upload Received Rejected Developer Rejected Invalid Binary Missing Screenshot Am I missing anything up until this point? If not, then am I correct to say that the only time I can change an app's Large Icon is when I update the application? Here's a more specific use case: My app is currently on sale, version 2.0 I have version 2.1 ready, and I want the update to coincide with a sale, so I also put a "SALE" banner on top of my large icon (what most devs are doing) I have to upload this "SALE" Large Icon when I upload the binary. If I wait until it's been reviewed, it's too late, and I'll have developer-reject the binary so I can fix it. Is this correct? Say I want the sale to last a week. So at the end of that week, I'll want to switch my Large Icon back to the pre-"SALE" version. Will I necessarily have to upload a new binary at that time? (Also posted on the Developer Forums, but it's getting no love there...)

• C++ Numerical Recipes &ndash; A New Adventure!

  - by JoshReuben

  I am about to embark on a great journey – over the next 6 weeks I plan to read through C++ Numerical Recipes 3rd edition http://amzn.to/YtdpkS I'll be reading this with an eye to C++ AMP, thinking about implementing the suitable subset (non-recursive, additive, commutative) to run on the GPU. APIs supporting HPC, GPGPU or MapReduce are all useful – providing you have the ability to choose the correct algorithm to leverage on them. I really think this is the most fascinating area of programming – a lot more exciting than LOB CRUD !!! When you think about it , everything is a function – we categorize & we extrapolate. As abstractions get higher & less leaky, sooner or later information systems programming will become a non-programmer task – you will be using WYSIWYG designers to build: GUIs MVVM service mapping & virtualization workflows ORM Entity relations In the data source SharePoint / LightSwitch are not there yet, but every iteration gets closer. For information workers, managed code is a race to the bottom. As MS futures are a bit shaky right now, the provider agnostic nature & higher barriers of entry of both C++ & Numerical Analysis seem like a rational choice to me. Its also fascinating – stepping outside the box. This is not the first time I've delved into numerical analysis. 6 months ago I read Numerical methods with Applications, which can be found for free online: http://nm.mathforcollege.com/ 2 years ago I learned the .NET Extreme Optimization library www.extremeoptimization.com – not bad 2.5 years ago I read Schaums Numerical Analysis book http://amzn.to/V5yuLI - not an easy read, as topics jump back & forth across chapters: 3 years ago I read Practical Numerical Methods with C# http://amzn.to/V5yCL9 (which is a toy learning language for this kind of stuff) I also read through AI a Modern Approach 3rd edition END to END http://amzn.to/V5yQSp - this took me a few years but was the most rewarding experience. I'll post progress updates – see you on the other side !

• Direct IO enhancements in OVM Server for SPARC 2.2(a.k.a LDoms2.2)

  - by user12611315

  The Direct I/O feature has been available for LDoms customers since LDoms2.0. Apart from the latest SR-IOV feature in LDoms2.2, it is worth noting a few enhancements to the Direct I/O feature. These are: Support for Metis-Q and Metis-E cards. These cards are highly requested for support and are worth mentioning because they are the only combo cards containing both FibreChannel and Ethernet in the same card. With this support, a customer can have both SAN storage and network access with just one card and one PCIe slot assigned to a logical domain. This reduces cost and helps when there are less number of slots in a given platform. The following are the part numbers for these cards. I have tried to put the platforms on which each card is supported, but this information can get quickly outdated. The accurate information can be found at the Support Document.  Card Name  Part Number  Platforms Metis-Q: StorageTek Dual 8Gb Fibre Channel Dual GbE ExpressModule HBA, QLogic SG-XPCIEFCGBE-Q8-N  SPARC T3-4, T4-4 Metis-E: StorageTek Dual 8Gb Fibre Chanel Dual GbE ExpressModule HBA, Emulex SG-XPCIEFCGBE-E8-N SPARC T3-4, T4-4  Additional cards added to the portfolio of supported cards. This is mainly Powerville based Ethernet cards, the part numbers for these cards as below:  Part Number  Description  7100477 Sun Quad Port GbE PCI Express 2.0 Low Profile Adapter, UTP  7100481 Sun Dual Port GbE PCI Express 2.0 Low Profile Adapter, MMF  7100483 Sun Quad Port GbE PCI Express 2.0 ExpressModule, UTP  7110486 Sun Quad Port GbE PCI Express 2.0 ExpressModule, MMF    Note:  Direct IO feature has a hard dependency on the Root domain(PCIe bus owner, here Primary domain). That is, rebooting the Root domain for any reason may impact the logical domains having PCIe slots assigned with Direct IO feature. So rebooting a root domain need to be carefully managed. Also apply the failure-policy settings as described in the admin guide and release notes to deal with unexpected cases.

• Cheapest Embedded System with Wireless Connectivity?

  - by geeko

  Problem: I'm trying to capture some information coming from keyboard, mouse and barcode reader connected to some PC via PS/2, USB and/or RS-232, before information get to PC and send it over the Internet to some central server. I'm thinking to do so by using some kind of hardware interface (middleware, if you like) between PC and input devices. I thought this interface can be embedded PC, PDA or simply some mobile phone with wireless connectivity. PS/2 and RS-232 could be converted to USB using some USB convector/hub that connects to one of these interface systems. Then some special API programming take place to communicate between PC, input devices and wireless server, in the form of application running on the interface system. What's the cheapest solution that can achieve this? Or possibly any other solution?

• Oracle Financials In the News

  - by Di Seghposs

  Coming off of OpenWorld and all the excitement around Oracle’s “Cloud” strategy, we thought we’d share what others had to say recently about Oracle’s financial solutions in and out of the cloud: Information Management, the educated reader’s choice for the latest news, commentary and feature content serving the information technology and business community, had an interesting blog post from Bill McNee of Saugatuck Technology, entitled, “A Bull Market for Finance Cloud Apps”. In the post, he highlights Oracle as one of the ‘significant players’ in the space… Oracle: As recently announced, Oracle is now aggressively marketing its Oracle Fusion Financials Cloud Service to midsize and large enterprise customers. While we anticipate that this solution set will primarily appeal to a portion of the existing Oracle customer footprint, rather than taking share from competitors, it is embedding some strong mobile and social capabilities that should help it gain traction. Read the full article - “A Bull Market for Finance Cloud Apps” Ventana Research, a leading benchmark research and advisory services firm, made mention to Oracle Fusion Financials in a recent blog post. While we all know ‘boring is cool’, it was cool to see Robert Kugel, SVP Research, discussing Oracle’s Fusion Financials strategy. Here’s some excerpts: “For at least the next five years I believe Oracle has a good strategy, because the transition from the existing Oracle ERP offerings to Fusion Financials can be less painful than similar migrations…” “Deploying Fusion GL can facilitate a more consistent and faster way to execute finance department functions.” “Fusion Financials is the go-forward accounting and financial applications suite that will coexist…” “Whether or not it’s time to migrate, I think all users of Oracle’s E-Business Suite, Oracle Applications, PeopleSoft and JD Edwards software should consider Fusion GL as part of an ongoing program to extract more value from their core financial systems.” Read the full article - “Oracle Fusion Financials: Boring is Cool”

• Application Scope v's Static - Not Quite the same

  - by Duncan Mills

  An interesting question came up today which, innocent as it sounded, needed a second or two to consider. What's the difference between storing say a Map of reference information as a Static as opposed to storing the same map as an application scoped variable in JSF?  From the perspective of the web application itself there seems to be no functional difference, in both cases, the information is confined to the current JVM and potentially visible to your app code (note that Application Scope is not magically propagated across a cluster, you would need a separate instance on each VM). To my mind the primary consideration here is a matter of leakage. A static will be (potentially) visible to everything running within the same VM (OK this depends on which class-loader was used but let's keep this simple), and this includes your model code and indeed other web applications running in the same container. An Application Scoped object, in JSF terms, is much more ring-fenced and is only visible to the Web app itself, not other web apps running on the same server and not directly to the business model layer if that is running in the same VM. So given that I'm a big fan of coding applications to say what I mean, then using Application Scope appeals because it explicitly states how I expect the data to be used and a provides a more explicit statement about visibility and indeed dependency as I'd generally explicitly inject it where it is needed.  Alternative viewpoints / thoughts are, as ever, welcomed...

• Which software to keep track of my project?

  - by Exa

  I'm about to start the first real phase of my game development which will consist of the acquisition of information, resources and the definition of where I want to go and what I will need for that. I just want to make sure that I'm prepared as best as possible before I actually start development. I don't like the thought of using Microsoft Word or Excel for my project management... I already worked with MS Project but I don't think it fits my needs. I need a software where I can easily maintain project steps, milestones, important issues, information about technologies and engines I use, as well as simple notes and thoughts I just want to write down. I usually prefer a whiteboard for stuff like that but unfortunately it's not a persistent way of storing. ;) Also writing it down the old-school way is something I can think of, but only for quick notes... Which software do you use for that? Are there commonly used programs? Is there any free software at all?

• Efficiently separating Read/Compute/Write steps for concurrent processing of entities in Entity/Component systems

  Setup I have an entity-component architecture where Entities can have a set of attributes (which are pure data with no behavior) and there exist systems that run the entity logic which act on that data. Essentially, in somewhat pseudo-code: Entity { id; map<id_type, Attribute> attributes; } System { update(); vector<Entity> entities; } A system that just moves along all entities at a constant rate might be MovementSystem extends System { update() { for each entity in entities position = entity.attributes["position"]; position += vec3(1,1,1); } } Essentially, I'm trying to parallelise update() as efficiently as possible. This can be done by running entire systems in parallel, or by giving each update() of one system a couple of components so different threads can execute the update of the same system, but for a different subset of entities registered with that system. Problem In reality, these systems sometimes require that entities interact(/read/write data from/to) each other, sometimes within the same system (e.g. an AI system that reads state from other entities surrounding the current processed entity), but sometimes between different systems that depend on each other (i.e. a movement system that requires data from a system that processes user input). Now, when trying to parallelize the update phases of entity/component systems, the phases in which data (components/attributes) from Entities are read and used to compute something, and the phase where the modified data is written back to entities need to be separated in order to avoid data races. Otherwise the only way (not taking into account just "critical section"ing everything) to avoid them is to serialize parts of the update process that depend on other parts. This seems ugly. To me it would seem more elegant to be able to (ideally) have all processing running in parallel, where a system may read data from all entities as it wishes, but doesn't write modifications to that data back until some later point. The fact that this is even possible is based on the assumption that modification write-backs are usually very small in complexity, and don't require much performance, whereas computations are very expensive (relatively). So the overhead added by a delayed-write phase might be evened out by more efficient updating of entities (by having threads work more % of the time instead of waiting). A concrete example of this might be a system that updates physics. The system needs to both read and write a lot of data to and from entities. Optimally, there would be a system in place where all available threads update a subset of all entities registered with the physics system. In the case of the physics system this isn't trivially possible because of race conditions. So without a workaround, we would have to find other systems to run in parallel (which don't modify the same data as the physics system), other wise the remaining threads are waiting and wasting time. However, that has disadvantages Practically, the L3 cache is pretty much always better utilized when updating a large system with multiple threads, as opposed to multiple systems at once, which all act on different sets of data. Finding and assembling other systems to run in parallel can be extremely time consuming to design well enough to optimize performance. Sometimes, it might even not be possible at all because a system just depends on data that is touched by all other systems. Solution? In my thinking, a possible solution would be a system where reading/updating and writing of data is separated, so that in one expensive phase, systems only read data and compute what they need to compute, and then in a separate, performance-wise cheap, write phase, attributes of entities that needed to be modified are finally written back to the entities. The Question How might such a system be implemented to achieve optimal performance, as well as making programmer life easier? What are the implementation details of such a system and what might have to be changed in the existing EC-architecture to accommodate this solution?

• What parameters to mdadm, to re-create md device with payload starting at 0x22000 position on backing storage?

  - by Adam Ryczkowski

  I try to recover from mdadm raid disaster, which happened when moving from ubuntu server 10.04 to 12.04. I know the correct order of devices from dmesg log, but given this information, I still cannot access the data. The superblocks look messy; the mdadm --examine for each disk is on this question on askubuntu By inspecting the raw contents of backing storage, I found the beginning of my data (the LUKS container in my case) at position 0x22000 relative to the beginning of the first partition in the raid. Question: What is the combination of options issued to "mdadm --create" to re-create mdadm that starts with the given offset? Bitmap size? PS. The relevant information from syslog when the system was healthy are pasted here.

• Installing Skype on 12.04 64 bit causes errors

  - by Wolfy87

  Hi there I am trying to install Skype through apt-get but I am having some trouble. The Skype package depends on skype-bin which is not found in my list of packages. So when trying to install Skype I get the following error. $ sudo apt-get install skype Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: skype : Depends: skype-bin but it is not installable E: Unable to correct problems, you have held broken packages. Does anyone know why this might happen? Am I missing a repository? I get similar results when downloading the .deb from their site. But it complains about ai32-libs not being installable. This is because it depends on another package that does not exist in my list. Please bear in mind that this is a custom install from the company I work for. They have secured it and I think they have updated it over time and skipped versions, possibly breaking things.
