• Creating Corporate Windows Phone Applications

  - by Tim Murphy

  Most developers write Windows Phone applications for their own gratification and their own wallets.  While most of the time I would put myself in the same camp, I am also a consultant.  This means that I have corporate clients who want corporate solutions.  I recently got a request for a system rebuild that includes a Windows Phone component.  This brought up the questions of what are the important aspects to consider when building for this situation. Let’s break it down in to the points that are important to a company using a mobile application.  The company want to make sure that their proprietary software is safe from use by unauthorized users.  They also want to make sure that the data is secure on the device. The first point is a challenge.  There is no such thing as true private distribution in the Windows Phone ecosystem at this time.  What is available is the ability to specify you application for targeted distribution.  Even with targeted distribution you can’t ensure that only individuals within your organization will be able to load you application.  Because of this I am taking two additional steps.  The first is to register the phone’s DeviceUniqueId within your system.  Add a system sign-in and that should cover access to your application. The second half of the problem is securing the data on the phone.  This is where the ProtectedData API within the System.Security.Cryptography namespace comes in.  It allows you to encrypt your data before pushing it to isolated storage on the device. With the announcement of Windows Phone 8 coming this fall, many of these points will have different solutions.  Private signing and distribution of applications will be available.  We will also have native access to BitLocker.  When you combine these capabilities enterprise application development for Windows Phone will be much simpler.  Until then work with the above suggestions to develop your enterprise solutions. del.icio.us Tags: Windows Phone 7,Windows Phone,Corporate Deployment,Software Design,Mango,Targeted Applications,ProtectedData API,Windows Phone 8

• Accessing SQL Server data from iOS apps

  - by RobertChipperfield

  Almost all mobile apps need access to external data to be valuable. With a huge amount of existing business data residing in Microsoft SQL Server databases, and an ever-increasing drive to make more and more available to mobile users, how do you marry the rather separate worlds of Microsoft's SQL Server and Apple's iOS devices? The classic answer: write a web service layer Look at any of the questions on this topic asked in Internet discussion forums, and you'll inevitably see the answer, "just write a web service and use that!". But what does this process gain? For a well-designed database with a solid security model, and business logic in the database, writing a custom web service on top of this just to access some of the data from a different platform seems inefficient and unnecessary. Desktop applications interact with the SQL Server directly - why should mobile apps be any different? The better answer: the iSql SDK Working along the lines of "if you do something more than once, make it shared," we set about coming up with a better solution for the general case. And so the iSql SDK was born: sitting between SQL Server and your iOS apps, it provides the simple API you're used to if you've been developing desktop apps using the Microsoft SQL Native Client. It turns out a web service remained a sensible idea: HTTP is much more suited to the Big Bad Internet than SQL Server's native TDS protocol, removing the need for complex configuration, firewall configuration, and the like. However, rather than writing a web service for every app that needs data access, we made the web service generic, serving only as a proxy between the SQL Server and a client library integrated into the iPhone or iPad app. This client library handles all the network communication, and provides a clean API. OSQL in 25 lines of code As an example of how to use the API, I put together a very simple app that allowed the user to enter one or more SQL statements, and displayed the results in a rather primitively formatted text field. The total amount of Objective-C code responsible for doing the work? About 25 lines. You can see this in action in the demo video. Beta out now - your chance to give us your suggestions! We've released the iSql SDK as a beta on the MobileFoo website: you're welcome to download a copy, have a play in your own apps, and let us know what we've missed using the Feedback button on the site. Software development should be fun and rewarding: no-one wants to spend their time writing boiler-plate code over and over again, so stop writing the same web service code, and start doing exciting things in the new world of mobile data!

• Monitor the Weather from Your Windows 7 Taskbar

  - by Asian Angel

  Keeping up with the weather forecast can be hard when you are extra busy with work. If you need a simple but nice looking way to integrate weather monitoring into your Taskbar then join us as we look at WeatherBar. Setting Up & Using WeatherBar To get started unzip the following files, place them in an appropriate “Program Files Folder”, and create a shortcut. When you start WeatherBar for the first time you will be presented with the following window and a random/default location. To get WeatherBar set up for your location there are only two settings to adjust (using the “Pencil & Gear Buttons”). Clicking on the “Pencil Button” will open up this small window…enter the name of your location and click “OK”. Next click on the “Gear Button” where you can choose the “Update Interval” and “Measurement Format” that best suits your needs. Click “OK” when finished and WeatherBar will be ready to go. That definitely looks nice. When you are finished viewing this window minimize it to the “Taskbar Icon” instead of clicking on the “Close Button”…otherwise the entire app will close. Left click on the “Taskbar Icon” to bring the window back up… Hovering the mouse over the “Taskbar Icon” provides a nice thumbnail of the weather forecast. Right clicking on the “Taskbar Icon” will display a nice mini forecast. Conclusion While WeatherBar may not be for everyone it does provide a nice easy way to monitor the weather from your “Taskbar” without taking up a lot of room.

• Base Pages and Interfaces for ASP.NET Pages

  - by geekrutherford

  For quite a while I have been using the concept of base pages when developing pages in ASP.NET applications. It is a wonderful method for exposing common functions to all of your applications pages and also overriding certain events for various purposes (i.e. dynamic themes).  Recently I found out a new developer will be joining my team. This prompted me to review the applications code for readability and ease of maintenance. I began adding comments through out the code behind for all pages within the application. While doing so I noted that I had used common method names for such things as loading data, configuring controls, applying filters, etc.   Bringing a new developer on board, I wanted to make the transition as seamless as possible while also ensuring they follow existing coding practices we already have in place. While I could have created virtual methods for the common page methods allowing them to overridden, what I really needed was a way to ensure the new developer implemented the same methods for each and every page. Thus I created an interface to force the issue.   Now, every page not only inherits the base page class but also implements an interface. This provides every page not only common functions and overridden page events but also imposes rules for implementing certain common methods :-)   Interface   public interface BasePageInterface { /// Configures page based on users security permissions. void CheckPermissions(); /// Configures Filter Form control for current page.  /// Ensure you have set the FilteredGrid and PageAjaxManager properties of the FilterForm control in PageLoad!!!  void ConfigureFilters(); /// Sets event handlers and default settings for controls on the current page. void ConfigureControls(); /// Exports data bound to grid in selected format. void ExportGridData(ExportFormat fmt); /// Loads data and binds to grid. /// Columns are turned on/off in grid depending on tab selected and users permissions.  void LoadData(); }   Page code-behind class definition:   public partial class MyPage : BasePage, BasePageInterface Note, you could not use an abstract class to accomplish this considering C# does not allow for multiple inheritance.  Nor could the base page class be abstract since it needs to inherit from the System.Web.UI.Page class in order to override page events.

• Oracle JDeveloper 11gR2 Cookbook book review

  - by Chris Muir

  I recently received a free copy of Oracle JDeveloper 11gR2 Cookbook published by Packt Publishing for review. Readers of technical cookbooks would know this genre of text includes problems that developers will hit and the prescribed solutions, in this case for Oracle's Application Development Framework (ADF).  Books like this excel themselves on excellent coverage, a logical progress of solutions through out the book, and providing a readable narrative around the numerous steps and code. This book progresses well through ADF application assembly, ADF Business Components, the view layer, security, deployment and tuning.  Each recipe had a clear introduction and I especially enjoyed the "There's more" follow up sections for some recipes that leads the reader onto related ideas and issues the reader really needs to be aware of. Also worthy of comment having worked with ADF for over 5 years, there certainly was recipes and solutions I hadn't encountered before, this book gets bonus points for that. As a reviewer what negatives can I give this text? The book has cast it's net too wide by trying to cover "everything from design and construction, to deployment, testing, debugging and optimization."  ADF is such a large and sophistication technology, this book with 100 recipes barely scrapes the surface.  Don't expect all your ADF problems to be solved here. In turn there is inconsistency in the level of problems and solutions.  I felt at the beginning the book was pitching itself at advanced problems to solve (that's great for me), but then it introduces topics like building a static View Object or train.  These topics in my opinion are fairly simple and are covered by the Oracle documentation just as well, they shouldn't have been included here.  In conclusion, ADF beginners will find this book worthwhile as it will open your eyes to the wider problems and solutions required for ADF, and experts for just the fact they can point junior programmers at the book for certain problems and say "get on with it". Is there scope for more ADF tombs like this?  Yes!  I'd love to see a cookbook specializing on ADF Business Components (hint hint to budding authors).

• Thoughts on schemas and schema proliferation

  - by jamiet

  In SQL Server 2005 Microsoft introduced user-schema separation and since then I have seen the use of schemas increase; whereas before I would typically see databases where all objects were in the [dbo] schema I now see databases that have multiple schemas, a database I saw recently had 31 (thirty one) of them. I can’t help but wonder whether this is a good thing or not – clearly 31 is an extreme case but I question whether multiple schemas create more problems than they solve? I have been involved in many discussions that go something like this: Developer #1> “I have a new function to add to the database and I’m not sure which schema to put it in” Developer #2> “What does it do?” Developer #1> “It provides data to a report in Reporting Services” Developer #2> “Ok, so put it in the [reports] schema” Developer #1> “Well I could, but the data will only be used by our Financial reporting folks so shouldn’t I put it in the [financial] schema?” Developer #2> “Maybe, yes” Developer #1> “Mind you, the data is supposed to be used for regulatory reporting to the FSA, should I put it in [regulatory]?” Developer #2> “Err….” You get the idea!!! The more schemas that exist in your database then the more chance that their supposed usages will overlap. I’m left wondering whether the use of schemas is actually necessary. I don’t view really see them as an aid to security because I generally believe that principles should be assigned permissions on objects as-needed on a case-by-case basis (and I have a stock SQL query that deciphers them all for me) so why bother using them at all? I can envisage a use where a database is used to house objects pertaining to many different business functions (which, in itself, is an ambiguous term) and in that circumstance perhaps a schema per business function would be appropriate; hence of late I have been loosely following this edict: If some objects in a database could be moved en masse to another database without the need to remove any foreign key constraints then those objects could legitimately exist in a dedicated schema. I am interested to know what other people’s thoughts are on this. If you would like to share then please do so in the comments. @Jamiet

• Make the Taskbar Buttons Switch to the Last Active Window in Windows 7

  - by The Geek

  The new Windows 7 taskbar’s Aero Peek feature, with the live thumbnails of every window, is awesome… but sometimes you just want to be able to click the taskbar button and have the last open window show up instead. Here’s a quick hack to make it work better. To better understand the problem, imagine having nine windows of the same type open on your screen, but you are primarily working in just one of the windows at a time. So every time you want to switch back, you have to click the taskbar button, and then choose the one you are using from the list, which can be pretty annoying… Now if you know your Windows 7 shortcuts, you’d know that you can simply hold down the Ctrl key while clicking on the taskbar button, and the last window will show up. In fact, you can keep holding down the Ctrl key and keep clicking, and Windows will cycle through the open windows. It’s a useful shortcut, but hardly something you want to do every single time. Instead, we’ll use a quick registry hack to make the normal click switch to the last open window—if you still want to see the thumbnail list, just hover your mouse over the button for half a second to see the full list. Manual Registry Hack for Last Active Window Open up regedit.exe through the start menu search or run box, and then head down to the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced Once you’re there, create a new 32-bit DWORD value on the right hand side, give it the name LastActiveClick, and set the value to 1. Once you are done, it should look something like this: Once you are done, you’ll have to log off and back on, or you can kill Explorer.exe through Task Manager and re-open it. Download the Registry Hack Instead Since you probably don’t feel like registry hacking, we’ve provided you an easy downloadable version. You can simply download the file, extract it, and then double-click on the LastActiveClick.reg file. Once you are done, you’ll have to log off and back on, just like with the manual registry hack.

• Focusing on Mobile @ Oracle OpenWorld

  - by Carlos Chang

  Plenty of exciting trends in the industry today: Cloud, Big Data, Mobile, etc. The first two are amazing of course, but for me, it's mobile, mobile and... MOBILE.   Why? Think back to the mozilla browser (Marc Andreessen's mozilla, not today's mozilla.org), Netscape and the nascent beginnings of the World Wide Web. Amazing times. Companies were just starting to set up their home pages, basic HTML, hyperlinks, images, ooooh, aaaah.  Yahoo! was *the* search engine back then. :-\   Anywhoo, I would pose that mobile today, we are in a similar junction. Sure, there's millions of apps on Apple's App Store and Google Play, but within the enterprise, it's just getting started. I'm talking about going beyond the simple, tactical apps such as calendaring, contacts or directory service lookup. And while mobile first a common mantra, I'm referring to mobile plus which includes and looks upon the whole enterprise holistically and adds new parameters, such as your GPS location, perhaps even your vital signs. (Apple's health kit?)  Everything is going mobile. Everything connected. But with the enterprise - scalability, security, integration, app management, user management, etc. Amazing times ahead. Ok, got that off my mind. Oracle OpenWorld 2014 - Going Mobile!  If you're coming to the big dance, I've highlighted some key mobile sessions below. And if you see me around, and there's a bar within reach, high five me for a beer.

• WIF, ADFS 2 and WCF&ndash;Part 1: Overview

  - by Your DisplayName here!

  A lot has been written already about passive federation and integration of WIF and ADFS 2 into web apps. The whole active/WS-Trust feature area is much less documented or covered in articles and blogs. Over the next few posts I will try to compile all relevant information about the above topics – but let’s start with an overview. ADFS 2 has a number of endpoints under the /services/trust base address that implement the WS-Trust protocol. They are grouped by the WS-Trust version they support (/13 and /2005), the client credential type (/windows*, /username*, /certificate*) and the security mode (*transport, *mixed and message). You can see the endpoints in the MMC console under the Service/Endpoints page. So in other words, you use one of these endpoints (which exactly depends on your configuration / system setup) to request tokens from ADFS 2. The bindings behind the endpoints are more or less standard WCF bindings, but with SecureConversation (establishSecurityContext) disabled. That means that whenever you need to programmatically talk to these endpoints – you can (easily) create client bindings that are compatible. Another option is to use the special bindings that come with WIF (in the Microsoft.IdentityModel.Protocols.WSTrust.Bindings namespace). They are already pre-configured to be compatible with the ADFS endpoints. The downside of these bindings is, that you can’t use them in configuration. That’s definitely a feature request of mine for the next version of WIF. The next important piece of information is the so called Federation Service Identifier. This is the value that you (at least by default) have to use as a realm/appliesTo whenever you are requesting a token for ADFS (e.g. in  IdP –> RSTS scenario). Or (even more) technically speaking, ADFS 2 checks for this value in the audience URI restriction in SAML tokens. You can get to this value by clicking the “Edit Federation Service Properties” in the MMC when the Service tree-node is selected. OK – I will come back to this basic information in the following posts. Basically I want to go through the following scenarios: ADFS in the IdP role ADFS in the R-STS role (with a chained claims provider) Using the WCF bindings for automatic token issuance Using WSTrustChannelFactory for manual token handling Stay tuned…

• Will you share your SQL Server configuration?

  - by Bill Graziano

  I regularly visit client sites and review their SQL Server configurations.  I come across all kinds of strange settings.  I’ve been thinking about a way to aggregate people’s configurations and see what’s common and what’s unique.  I used to do that with polls on SQLTeam.com.  I think we can find out more interesting things if we look at combinations of settings in relation to size and volume. I’ve been working on an application for another project that is similar.  It will be fairly easy to use that code for this.  I can have something up and running in a few days – if people are interested in it.  I admit that I often come up with ideas that just don’t make sense.  This may be one of them.  One of your biggest concerns has be how secure your data is.  My solution is not to store anything identifying.  The instance name and database names can both be “anonymized” and I don’t store the machine name or IP address or anything to do with logins. Some of the questions I’m curious about are: At what size database does the Enterprise Edition become prevalent? Given the total size of the databases how much RAM is common? How many people have multiple data files?  At what size does that become prevalent? How common is database mirroring?  Replication?  Log shipping? How common is full recovery mode?  At what data size does it become prevalent? I think those are all questions that are easy to answer -- with the right data.  The big question is whether or not people will share their SQL Server configurations.  I understand that organizations in regulated or high security environments can’t participate.  But I think that leaves many, many people that can.  Are you willing to share your configuration and learn about others?  I have a simple sign up form here.  It’s actually a mailing list signup that also captures your edition, number of servers and largest database.  The list will only be used for this project.  Is your SQL Server is configured correctly?  Do you wonder what the next step is as your data grows?  Take a second and sign up.

• Addressing threats introduced by the BYOD trend

  - by kyap

  With the growth of the mobile technology segment, enterprises are facing a new type of threats introduced by the BYOD (Bring Your Own Device) trend, where employees use their own devices (laptops, tablets or smartphones) not necessarily secured to access corporate network and information.In the past - actually even right now, enterprises used to provide laptops to their employees for their daily work, with specific operating systems including anti-virus and desktop management tools, in order to make sure that the pools of laptop allocated are spyware or trojan-horse free to access the internal network and sensitive information. But the BYOD reality is breaking this paradigm and open new security breaches for enterprises as most of the username/password based systems, especially the internal web applications, can be accessed by less or none protected device.To address this reality we can adopt 3 approaches:1. Coué's approach: Close your eyes and assume that your employees are mature enough to know what he/she should or should not do.2. Consensus approach: Provide a list of restricted and 'certified' devices to the internal network. 3. Military approach: Access internal systems with certified laptop ONLYIf you choose option 1: Thanks for visiting my blog and I hope you find the others entries more useful :)If you choose option 2: The proliferation of new hardware and software updates every quarter makes this approach very costly and difficult to maintain.If you choose option 3: You need to find a way to allow the access into your sensitive application from the corporate authorized machines only, managed by the IT administrators... but how? The challenge with option 3 is to find out how end-users can restrict access to certain sensitive applications only from authorized machines, or from another angle end-users can not access the sensitive applications if they are not using the authorized machine... So what if we find a way to store the applications credential secretly from the end-users, and then automatically submit them when the end-users access the application? With this model, end-users do not know the username/password to access the applications so even if the end-users use their own devices they will not able to login. Also, there's no need to reconfigure existing applications to adapt to the new authenticate scheme given that we are still leverage the same username/password authenticate model at the application level. To adopt this model, you can leverage Oracle Enterprise Single Sign On. In short, Oracle ESSO is a desktop based solution, capable to store credentials of Web and Native based applications. At the application startup and if it is configured as an esso-enabled application - check out my previous post on how to make Skype essso-enabled, Oracle ESSO takes over automatically the sign-in sequence with the store credential on behalf of the end-users. Combined with Oracle ESSO Provisioning Gateway, the credentials can be 'pushed' in advance from an actual provisioning server, like Oracle Identity Manager or Tivoli Identity Manager, so the end-users can login into sensitive application without even knowing the actual username and password, so they can not login with other machines rather than those secured by Oracle ESSO.Below is a graphical illustration of this approach:With this model, not only you can protect the access to sensitive applications only from authorized machine, you can also implement much stronger Password Policies in terms of Password Complexity as well as Password Reset Frequency but end-users will not need to remember the passwords anymore.If you are interested, do not hesitate to check out the Oracle Enterprise Single Sign-on products from OTN !

• Can working exclusively with niche apps or tech hurt your career in software development? How to get out of the cycle? [closed]

  - by Keoma

  I'm finding myself in a bit of a pickle. I've been at a pretty comfortable IT group for almost a decade. I got my start here working on web development, mostly CRUD, but have demonstrated the ability to figure out more complex problems. I'm not a rock star, but I have received many compliments on my programming aptitude, and technologists and architects have commented on my ability to pick things up (for example, I recently learned a very popular web framework that shall remain nameless since I don’t want to be identified). My problem is that, over time, my responsibilities have been shifting towards work such as support or ‘development’ with some rather niche products (afraid to mention here due to potential for being identified). Some of this work, if it includes anything resembling coding, is very menial scripting in languages such as Powershell or VBScript. The vast majority of the time, however, a typical day consists of going back and forth with the product’s vendor support to send them logs and apply configuration changes or patches they recommend. I’m basically starved for some actual software development. However, even though I’m more than capable of doing that development work (and actually do a much better job at it than anything else), our boss is more interested in the kind of work I mentioned above, her reasoning being that since no one else in the organization wants to do it, it must mean job security. This has been going on for close to 3 years, and the only reason I have held on is on the promise that we would eventually get more development projects assigned to us. Well, that turned out not to be true at all. A recent talk with the boss has just made it more explicitly clear, as she told me in no uncertain terms that it’s very likely that development work (web or otherwise) would go to another group. The reason given to me is that our we don’t have enough resources in our group to handle that. So now I find myself in the position that I either have to stay in what has essentially become a dead end IT job that is tied to the fortunes of a niche stack of apps, or try to find a position that will be better for my long term career. My problem (is it a problem?), however, is that compared to others, my development projects in the last three years are very sparse in number. To compound things, projects using the latest and most popular frameworks, amount to the big fat number of just one—with no work of that kind in the foreseeable future. I am very concerned that this sparseness in my resume is a deficit, and that it will hurt my chances of landing a different job. I’m also wondering how much it will hurt me, and whether that can be ameliorated with hobby projects of my own. I guess I’m looking for opinions. Thank you very much for reading.

• Need help identifing what resources (eg. In MIT OpenCourseWare) can help me prepare for a test [closed]

  - by jiewmeng

  I am entering uni soon. I can sit for a placement test to see if I elegible for exemptions. The details are http://www.comp.nus.edu.sg/undergraduates/TestScope11_12.html Or CS2100 Computer Organisation (please click title) The objective of this module is to familiarise students with the fundamentals of computing devices. Through this module students will understand the basics of data representation, and how the various parts of a computer work, separately and with each other. This allows students to understand the issues in computing devices, and how these issues affect the implementation of solutions. Topics covered include data representation systems, combinational and sequential circuit design techniques, assembly language, processor execution cycles, pipelining, memory hierarchy and input/output systems. Recommended Textbooks Digital Design: Principles and Practices [DDPP] by John F. Wakerly, Prentice-Hall. ISBN 0-13-324500-4. Computer Organizations and Design (The hardware/software interface) by David A. Patterson and John L. Hennessy. CS2105 Introduction to Computer Networks (please click title) This course aims to provide a broad introduction to computer networks and some appreciations of network application programming. It covers a range of topics including basic data communication and computer network concepts, protocols, networked computing concepts and principles, network applications development and network security. The emphasis of teaching is on the working principles and application of computer networks. As an integral part of the course, tutorials and practical assignments enforcing learning will also be given. These assignments provide an early exposure in network application programming and they should be able to complete by using personal computers and school's network facilities. Topics included: An overview of computer networks and the Internet Basic data communications Application layer Transport layer Network layer and routing Link layer and local area networks Recommended Textbook James F. Kurose & Keith W. Ross, Computer networking: A top-down approach featuring internet, Addison Wesley, 2001 I am wondering what resources eg. MIT OpenCourseWare or other universities resources are available to help he perpare for these particular modubles. I am thinking does the Networking one look like CCNA? The computer oragization. Its like electronics, assembly etc? I learnt some electronics in Poly but looking at the sample papers, uni looks very different... I have about 1 month to prepare if I want any chance of exempting from these modules :) any help?

• fdisk shows overlapping partitions

• Facial Recognition for Retail

  - by David Dorf

  My son decided to do his science project on how the brain recognizes faces.  Faces are so complicated and important that the brain has a dedicated area for just that purpose.  During our research, we came across some emerging uses for facial recognition in the retail industry. If you believe the movies, recognizing faces as they walk by a camera is easy for computers but that's not the reality.  Huge investments are being made by the U.S. government in this area, with a focus on airport security.  Now, companies like Eye See are leveraging that research for marketing purposes.  They do things like track eyes while viewing newspaper ads to see which ads get more "eye time."  This can help marketers make better placement and color decisions. But what caught my eye (that was too easy) was their new mannequins that watch shoppers.  These mannequins, being tested at European retailers like Benetton, watch shoppers that walk by and identify their gender, race, and age.  This helps the retailer better understand the types of customers being attracted to the outfit on the mannequin.  Of course to be most accurate, the software has pictures of the employees so they can be filtered out.  Since the mannequins are closer to the shoppers and at eye-level, they are more accurate than traditional in-ceiling LP cameras. Marketing agency RedPepper is offering retailers the ability to recognize loyalty shoppers at their doors using Facedeal.  For customers that have opted into the program, when they enter the store their face is recognized and they are checked in.  Then, as a reward, they are sent an offer on their smartphone. It won't be long before retailers begin to listen to shoppers are they walk the aisles, then keywords can be collected and aggregated to give the retailer an idea of what people are saying about their stores and products.  Sentiment analysis based on what's said or even facial expressions can't be far off. Clearly retailers need to be cautions and respect customer privacy.  That's why these technologies are emerging slowly.  But since the next generation of shoppers are less concerned about privacy, I expect these technologies to appear sporadically in the next five years then go mainstream.  Time will tell.

• Exchange 2010, Exchange 2003 Mail Flow issue

  - by Ryan Roussel

  While performing the initial Exchange 2010 deployment for a customer migrating from Exchange 2003, I ran into an issue with mail flow between the two environments.  The Exchange 2003 mailboxes could send to Exchange 2010, as well as to and from the internet.  Exchange 2010 mailboxes could send and receive to the internet, however they could not send to Exchange 2003 mailboxes.   After scouring the internet for a solution, it seemed quite a few people were experiencing this issue with no resolution to be found, or at least not easily.  After many attempts of manually deleting and recreating the routing group connectors,  I finally lucked onto the answer in an obscure comment left to another blogger.   If inheritable permissions are not allowed on the Exchange 2003 object in the Active Directory schema, exchange server authentication cannot be achieved between the servers.   It seems when Blackberry Enterprise Server gets added to 2003 environments, a lot of Admins get tricky and add the BES Admin user explicitly to the server object  to allow  inheritance down from there to all mailboxes.  The problem is they also coincidently turn off inheritance to the server object itself from its parent containers.  You can re-establish inheritance without overwriting the existing ACL however so that the BES Admin can remain in the server object ACL.   By re-establishing inheritance to the 2003 server object, mail flow was instantly restored between the servers.    To re-establish inheritance: 1. Open ASDIedit by adding the snap-in to a MMC (should be included on your 2008 server where Exchange 2010 is installed) 2. Navigate to Configuration > Services > Microsoft Exchange > Exchange Organization > Administrative Groups > First Administrative Group > Servers 3. In the right pane, right click on the CN=Server Name of your Exchange 2003 Server, select properties 4. Navigate to the Security tab, hit advanced toward the bottom. 5. Check the checkbox that reads “include inheritable permissions” toward the bottom of the dialogue box.

  Please note that exam results for all Oracle Certification exams will be accessed through CertView, starting October 30th, 2012. Exam results will no longer be available at the test center, or on the Pearson VUE website. Candidates will receive an email from Oracle within 30 minutes of completing the exam to let them know that their exam results are available on CertView. Candidates must have an Oracle Web Account to access CertView. This new process applies to exam results for all Oracle Certification exams - proctored and non-proctored as well beta exams. CertView, Oracle's self-service certification portal will be the partners’ one stop source for all their certification and exam history! Other benefits of this change include: driving all candidates to have an Oracle Web Account which will lead to tighter integration with Oracle University records in the future, increased security around data privacy and a higher validity rate for candidate email addresses. Existing benefits of CertView include, self-service access to exam and certification records and logos, and access to Oracle's self service certification verification.

• Getting a virus is *very* annoying

  - by bconlon

  I spent most of yesterday removing an annoying virus from my PC. I feel slightly foolish for getting one in the first place, but after so many years I guess I was always going to eventually succumb. I was also a little surprised at the failure of various tools at removing it. The virus would redirect the browser to websites including ‘licosearch’, ‘hugosearch’ and ‘facebook’, and the disk would be thrashing away infecting dlls in some way. I had the full up to date version of McAfee installed. This identified that there was an issue in some dlls on the system and was able to ‘fix’ them. But they kept getting re-infected. So I installed Microsoft Security Essentials and this too was able to identify and ‘fix’ the infected dlls. The system scans take forever and I really expected better results. I also tried Malwarebytes, Hitman Pro, AVG and Sophos to no avail. Eventually I thought I’d investigate myself. It turned out that on reboot, the virus would start 3 instances of Firefox.exe which I’m guessing would do bad things including infecting as many dlls on the system as possible. I removed Firefox and the virus cleverly then launched 3 instances of Chrome! So I uninstalled Chrome and yes, it then started to launch 3 instances of iexplore.exe. If I’m honest, by this stage I was just seeing if it would be able to use any of the browsers! As it was starting these on reboot, I looked in my User Startup folder and there was a <randomly named>.exe and several log files. I deleted these and rebooted. When I looked they had been recreated. So I then looked in the registry Run and RunOnce entries: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Sure enough there were entries to run a file in C:\Program Files\<random name folder>\<random name file>.exe. I deleted this and rebooted and it was fixed. I also looked in the event log and found a warning that Winlogon had failed to start the file C:\Program Files\<random name folder>\<random name file>.exe So I also checked HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and this entry had also been changed. Finally I ran a full system scan to clean up any infected dlls. I hope it’s gone for good!  #

• Understanding the levels of computing

  - by RParadox

  Sorry, for my confused question. I'm looking for some pointers. Up to now I have been working mostly with Java and Python on the application layer and I have only a vague understanding of operating systems and hardware. I want to understand much more about the lower levels of computing, but it gets really overwhelming somehow. At university I took a class about microprogramming, i.e. how processors get hard-wired to implement the ASM codes. Up to now I always thought I wouldn't get more done if learned more about the "low level". One question I have is: how is it even possible that hardware gets hidden almost completely from the developer? Is it accurate to say that the operating system is a software layer for the hardware? One small example: in programming I have never come across the need to understand what L2 or L3 Cache is. For the typical business application environment one almost never needs to understand assembler and the lower levels of computing, because nowadays there is a technology stack for almost anything. I guess the whole point of these lower levels is to provide an interface to higher levels. On the other hand I wonder how much influence the lower levels can have, for example this whole graphics computing thing. So, on the other hand, there is this theoretical computer science branch, which works on abstract computing models. However, I also rarely encountered situations, where I found it helpful thinking in the categories of complexity models, proof verification, etc. I sort of know, that there is a complexity class called NP, and that they are kind of impossible to solve for a big number of N. What I'm missing is a reference for a framework to think about these things. It seems to me, that there all kinds of different camps, who rarely interact. The last few weeks I have been reading about security issues. Here somehow, much of the different layers come together. Attacks and exploits almost always occur on the lower level, so in this case it is necessary to learn about the details of the OSI layers, the inner workings of an OS, etc.
