• Knowledge Management Feedback

  - by Robert Schweighardt

  Did you know that you can provide feedback on Knowledge Management (KM) articles? It's nice to read a technical article that is well-written, the grammar and spelling are correct, the information is up to date, concise, to the point, easy to understand and it flows from one paragraph to another.  And though we always strive for a well-written article, it doesn't always come out that way. Knowledge Management articles are written by Oracle Support Engineers and we welcome your feedback.  Providing feedback helps to improve Oracle's Knowledge Base.  If you're reading a KM article and you have a comment, please let us know about it.  Maybe it's just to fix a spelling or grammatical error.  Maybe there's a broken link that needs to be fixed.  Maybe it's a suggestion to provide additional information.  Maybe the article contains incorrect information.  Maybe some information in the article is outdated.  Maybe something is not clear in the article.  Whatever it is, we want to hear about it.  We value your input! When you provide feedback it goes directly to the owner of the article.  The owner carefully reviews the comment and decides whether or not to implement it.  Most comments are implemented and we strive to implement them within a week!  For those comments that are not implemented, there is normally a good reason.  It may not be feasible to implement the suggestion or the suggestion may not be correct.  We don't take the decision lightly! So how do you provide feedback? Providing feedback on a KM article depends on whether you're a customer or an Oracle Employee. Customer 1. In the upper right hand corner of the article, click on the little +/- Rate this document icon: Note: The grayed out Comments (0) link will only show a number when there are open comments that are still being evaluated. 2. In the Article Rating window, complete as many of the following optional fields as you like and then click the Send Rating button: Rate the article as Excellent, Good or Poor Specify whether the article helped you or not Specify the ease of finding the article Provide whatever comments you have Employee The interface for Oracle Employees is a little bit different, there are more options. 1. The +/- Rate this document icon is also available to employees and is identical to what the customers have.  Please see Customer section above. 2. The Show document comments link shows all comments that have ever been submitted for the article 3. Employees have an additional way to submit a comment.  Click on the little + Add Comment icon: 4. Fill out the Add Comment fields and click the Add Comment button: We look forward to your feedback!

• Oracle WebCenter: Common User Experience Architecture

  - by kellsey.ruppel(at)oracle.com

  You may remember that the key goals of the new release of WebCenter are providing a Modern User Experience, unparalleled Application Integration, converging all the best of the existing portal platforms into WebCenter and delivering a Common User Experience Architecture.  In previous weeks we've provided an overview of Oracle WebCenter and discussed some of the other key goals and this week, we'll focus on how the new release of Oracle WebCenter delivers a Common User Experience Architecture.When Oracle talks about a Common User Experience Architecture, it really focuses on a core set of areas.  First, the way that information is accessed needs to be consistent and extensible so that as requirements change, the applications don't need to be rewritten for every change. Second, this information access layer needs to be securely accessible to any application, site, or any other channel that needs to leverage this information.  Third, there needs to be a consistent presentation layout, Oracle calls it a UI shell, so that all resources can fit together in a useable, productive way.  Fourth, there needs to be a common set of design patterns for how different menus, features, and services fit into this UI Shell for broad and productive usability.  Fifth, there needs to be a set of design patterns for the individual services that plug into this UI shell so that end users can move from one module of the application to another without new learning.  Finally, all of these layers need to be customizable in an easy way that insulates IT from patching and upgrading problems and allows the business owners the agility to quickly change with the market conditions.As Oracle has already announced, we will release our next generation of enterprise applications called Oracle Fusion Applications.  We have thousands of developers building these applications that all had different programming tool experience and UI design experience.  We've educated over 6,000 developers building Oracle Fusion Applications to leverage these Common User Experience Architecture patterns to speed their learning curve of the new Java standards as well as SOA principles to deliver a revolutionary new set of applications.  You could imagine the big challenge with getting all these developers with different backgrounds and different UI design skills to deliver a completely integrated application user experience.  This is why Oracle invested heavily in designing this Common User Experience Architecture, based on Oracle WebCenter and the Oracle Application Development Framework (ADF).  It pulls together the best practices and design patterns that Oracle development required in order to bring Fusion Applications to market and Oracle WebCenter is the user experience layer that all of this is surfaced through.  In this way, customers can quickly brand a deployment for new partnerships without having to redevelop a new site.  Or they can quickly add new options to the UI Shell to enable their line of business managers to quickly adapt to a new competitive product.  And with the core integration of the activities to produce a Business Activity Stream, customers are able to stay on top of all their key business actions when they happen as they happen and more importantly, the system can recommend actions or resources to help act on these activities.And we've authored this whole set of design patterns for Oracle development to take advantage of in delivering Fusion Applications.  We're also applying these design patterns to our existing eBusiness Suite, Peoplesoft, Siebel, and JD Edwards applications so that they can tie in the exact same way that Fusion Applications has been brought together.  This will provide customers with a complete Common User Experience Architecture for their entire ecosystem of applications within their enterprise whether they are from Oracle, another vender, or custom built applications. And this is all provided in the new release of Oracle WebCenter.  These design patterns cover elements around delivering a complete, aggregated menu of all the capabilities that their role allows independent of which application they are trying to access.   It means that as they move from one application to another, they will have a consistent user experience.  And if they are using an Oracle application, any customizations that are made to the application are preserved and managed through upgrades and patches.Be sure to check back this week as we share more information and resources on Oracle's Common User Experience Architecture.

• SQL SERVER – Learn SQL Server 2014 Online in a Day – My Latest Pluralsight Course

  - by Pinal Dave

  Click here watch SQL Server 2014 Administration New Features.  SQL Server 2014 was released earlier this year and it has been extremely popular in Microsoft world. Here is the announcement for everyone, who have been asking me to build a tutorial around SQL Server 2014. I have authored latest Pluralsight courses on the subject of SQL Server 2014. This course is 4 hours and 17 minutes long, but the best part is that this course contains all the latest features of SQL Server 2014. I have build this course with the assumption that DBA is familiar with earlier versions of SQL Server and wants to explore and learn new features of SQL Server 2014. The Challenge I Faced The biggest challenge I faced was how to come up with the outline for the course. The reason is that there are so many different features introduced in SQL Server 2014 that is will be difficult to cover each of the features in a single course. I wanted to cover the topics which are the most relevant and useful to developers, but in addition I also wanted to cover the topics which may be useful to develop if they know that they exists in the product. I finally decided to depend on blog readers and few of the SQL Experts. I reached out to selected 20 people via email and gave them a list of the topics which I should be covering in this course. They all work in different organizations and have a good understanding about the need of the DBA and Developers. Based on their feedback, I was able to come up with a very good outline which is currently very popular with Pluralsight library. Lots of people have asked me how was I able to come up with a course content outline so accurately. The credit for the same goes to the developers and DBA, who have voted in the topics and have helped me to build a very solid outline for the course. Outline of the Course Here is a quick outline for the course: Introduction Backup Enhancements Security Enhancements Columnstore Enhancements Online Data Operations Enhancements Enhancements with Microsoft Azure SSD Buffer Pool Extensions Resource Governor IO Miscellaneous Features Online Index Rebuilding Live Plans for Long Running Queries Transaction Durability Cardinality Estimation In Memory OLTP Optimization Well, I had a great fun working on the topics which I have mentioned in the outline. I am very confident that once you start with the course, you will indeed understand how each of the topics builds and presented. I have made sure that each of the topic has a vivid and clear story to begin with. I first explain the story and right after that I explain the concept. Who Should Attend This Course Everyone who has basic knowledge of SQL Server and wants to update themselves with SQL Server 2014. They should attend this course. One thing I have made sure that this course is easy to understand and I have decided complex subject into multiple parts. This way the learning is progressive and anyone with a poor knowledge of the subject can have enough time to understand the presented concept. Screenshot of the Course Here are few of the screenshot of the courses. How to Watch Video Course This course is available at Pluralsight, and you will need a valid login to Pluralsight. If you do not have Pluralsight login, you can quickly sign up for the FREE Trial.

• Why I&rsquo;m Getting an iPad

  - by andrewbrust

  I have never purchased an Apple product in my life.  That’s a “true fact.”  And, for that matter, the last Apple product I really wanted was an Apple IIe, back in the 1980s.  I couldn’t afford it though (I was in high school), so I got a Commodore 64 instead…it had the same microprocessor, after all.  If the iPhone were on Verizon, I probably would have picked one up in December, when I got my Droid.  And if the iPod Touch worked with my Napster subscription (which of course it does not, but my Sonos does) I might have picked on of those instead. That’s three strikes, but Apple’s not out.  I’ve decided I want the iPad.  Why?  Well, to start with, my birthday is March 31st…the iPad comes out on April 3rd, and my wife wanted to know what to get me.  Also, my house is a 7-minute walk from the Apple Store on West 14th Street in Manhattan.  This makes it easy to get my pre-ordered device on launch day, and get home quickly with it.  Oh, and I agreed to write an article for Redmond Magazine, the fee for which will pay for the device…that way the birthday present doesn’t have to be an extravagant expense.  Plus, I’m a contrarian, so I want to buy the one device from Apple that the fanboys have actually panned. Think those are bad reasons? How about this: I want to experience iPhone and iPad development and, although my app will probably never hit the App Store and run on the actual device, I still think owning one will help me develop something better.  i want to see if the slate form factor has good business usage scenarios.  I want to see if Business Intelligence technology on a device like this can work.  Imagine a dashboard on this thing. And, for the consumer experience, I really want a touch device on which I can surf the Web while I’m in the kitchen, or on the couch.  I don’t want the small form factor of my phone, I don’t want to use my TV, and I don’t want a keyboard that will get dirty or in my way. I don’t want to watch movies on it (my TV is good for that), so I don’t care that the iPad has a 4:3 screen.  I don’t want to read books on it, so I don’t care that the display is backlit LCD, rather than eInk. But really what I want is to understand, first hand, why people have such brand loyalty to Apple.  I know the big reasons; I’m not detached from society.  But I want to know the subtle points of what Apple does really well, and also what they do poorly.  And I’d like to know, once and for all, if Microsoft can beat Apple, if Microsoft can think the right way to beat Apple and if Microsoft should  even try to beat Apple. I expect to share my thoughts on these questions, as they develop.

• Why Your ERP System Isn't Ready for the Next Evolution of the Enterprise

  - by [email protected]

  By ken.pulverman on March 24, 2010 8:51 AM ERP has been the backbone of enterprise software. The data held in your ERP system is core of most companies. Efficiencies gained through the accounting and resource allocation through ERP software have literally saved companies trillions of dollars. Not only does everything seem to be fine with your ERP system, you haven't had to touch it in years. Why aren't you ready for what comes next? Well judging by the growth rates in the space (Oracle posted only a 3% growth rate, while SAP showed a 12% decline) there hasn't been much modernization going on, just a little replacement activity. If you are like most companies, your ERP system is connected to a proprietary middleware solution that only effectively talks with a handful of other systems you might have acquired from the same vendor. Connecting your legacy system through proprietary middleware is expensive and brittle and if you are like most companies, you were only willing to pay an SI so much before you said "enough." So your ERP is working. It's humming along. You might not be able to get Order to Promise information when you take orders in your call center, but there are work arounds that work just fine. So what's the problem? The problem is that you built your business around your ERP core, and now there is such pressure to innovate your business processes to keep up that you need a whole new slew of modern apps and you need ERP data to be accessible from everywhere. Every time you change a sales territory or a comp plan or change a benefits provider your ERP system, literally the economic brain of your business, needs to know what's going on. And this giant need to access and provide information to your ERP is only growing. What makes matters even more challenging is that apps today come in every flavor under the Sun™. SaaS, cloud, managed, hybrid, outsourced, composite....and they all have different integration protocols. The only easy way to get ahead of all this is to modernize the way you connect and run your applications. Unlike the middleware solutions of yesteryear, modern middleware is effectively the operating system of the enterprise. In the same way that you rely on Apple, Microsoft, and Google to find a video driver for your 23" monitor or to ensure that Word or Keynote runs, modern middleware takes care of intra-application connectivity and process execution. It effectively allows you to take ERP out of the middle while ensuring connectivity to your vital data for anything you want to do. The diagram below reflects that change. In this model, the hegemony of ERP is over. It too has to become a stealthy modern app to help you quickly adapt to business changes while managing vital information. And through modern middleware it will connect to everything. So yes ERP as we've know it is dead, but long live ERP as a connected application member of the modern enterprise. I want to Thank Andrew Zoldan, Group Vice President Oracle Manufacturing Industries Business Unit for introducing me to how some of his biggest customers have benefited by modernizing their applications infrastructure and making ERP a connected application. by John Burke, Group Vice President, Applications Business Unit

• Sorry about the wait.

  - by Ratman21

  In the last two days have been trying remove “Iolo System Mechanic Professional” (With anti-virus and FireWall) from 3 of the 5 pc’s we have (3 lap tops and two Desk tops) as it was going to expire on the 13th.   So I could replace them with a free anti-virus (AVG) and just use the windows fire wall. I have been using the same set up on one of my desk tops (XP Pro) for 8 months and one of the Lap tops (Vista) for 5 months.   The problem was that System Mechanic did not want to go. Even after using the uninstall option on the desk top (my main PC, well its that because has the larger of all the PC’s hard drives but, is the oldest and runs XP home) and using Ccleaner to try and remove it.  It was still showing up as there and after I went a head and tried installing AVG and ran it. I found that the TCP/IP module was missing.  So no internet, I had to restore the PC back to the 1st to get the module back and then install AVG (after making sure window firewall was back on. I didn’t check that on the first try). Got the PC back to normal, very late last night. Only one of the two lap tops was easy but, even at that there are still some parts of System Mechanic on it but, AVG and firewall are working.   I may try an hunt down parts of System Mechanic on it and delete them on this lap top. Which was what finally had to do on the one of the Lap tops (also XP Home) as it would not uninstall after I restored the PC back to the 4th. So delete, delete, delete and Ccleaner (one dl file would not delete though). And I just finish installing AVG and now running a scan on the lap top. So all of this took two days (well three counting today). I started late Friday night and just finishing up now.   I only started this switch over after I had finished my Job search for day on Friday.   As for blogging on Tuesday, Wednesday and Thursday, I was busy and by the end of the day was too tired to blog, that and was hung up still on that 2nd dare of The Love Dare. So I cleaned the house, while she was out of the house. I mean, I cleaned, not just vacuumed house I cleaned the kitchen counter tops and the sinks. Did the dishes and some of the laundry over two of the those days.   As to the third day of Love Dare which is “Love is not selfish” and the dare “Whatever you put your time, energy, and money into will become more important to you. It’s hard to care for something you are not investing in. Along with restraining from negative comments, buy your spouse something that says, I was thinking of you today.”   Being on a very limited income, a lot of normal guy buying for girls is out (for one thing, the comment why did you waste our money on flowers, etc, etc, would come up. Not from me though). So that one is on hold till money issues are not a problem (no that does not mean never). The 4th day “Love is thoughtful” and the dare “Contact your spouse sometime during the business of the day. Have no agenda other than asking how he or she is doing and if there is anything you could do for them”.   I did this dare while I was still working with census last week and trying to do the dares. Well I start my CCNA classes Monday the 15th and I move on to the next Love Dare day “Love is not rude”.

• DataBinder Eval and Indexed properties

  - by erwin21

  As you probably know you can “Eval” an array property like below: <%# Eval("MyArray[0].Title") %> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }But what if your data object has indexed property? how do “Eval” that? Well it’s easier then you think it is: <%# Eval("[0]") %> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }And if your indexed property is based on for example a NameValueCollection you can “Eval” it like this: <%# Eval("[key]") %> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } As you see it’s very easy to “Eval” this kind of properties in you web application.

• SQL – Step by Step Guide to Download and Install NuoDB – Getting Started with NuoDB

  - by Pinal Dave

  Let us take a look at the application you own at your business. If you pay attention to the underlying database for that application you will be amazed. Every successful business these days processes way more data than they used to process before. The number of transactions and the amount of data is growing at an exponential rate. Every single day there is way more data to process than before. Big data is no longer a concept; it is now turning into reality. If you look around there are so many different big data solutions and it can be a quite difficult task to figure out where to begin. Personally, I have been experimenting with a lot of different solutions which allow my database to scale immediately without much hassle while maintaining optimal database performance.  There are for sure some solutions out there, but for many I even have to learn their specific language and there is a lot of new exploration to do. Honestly, what I prefer is a product, which works with the language I know (SQL) and follows all the RDBMS concepts which I am familiar with (ACID etc.). NuoDB is one such solution.  It is an operational NewSQL database built on a patented emergent architecture with full support for SQL and ACID guarantees. In this blog post, I will explore how one can download and install NuoDB database. Step 1: Follow me and go to the NuoDB download page. Simply fill out the form, accept the online license agreement, and you will be taken directly to a page where you can select any platform you prefer to install NuoDB. In my example below, I select the Windows 64-bit platform as it is one of the most popular NuoDB platforms. (You can also run NuoDB on Amazon Web Services but I prefer to install it on my local machine for the purposes of this blog). Step 2: Once you have downloaded the NuoDB installer, double click on it to install it on the Windows platform. Here is the enlarged the icon of the installer. Step 3: Follow the wizard installation, as it is pretty straight forward and easy to do so. I have selected all the options to install as the overall installation is very simple and it does not take up much space. I have installed it on my C drive but you can select your preferred drive. It is quite possible that if you do not have 64 bit Java, it will throw following error. If you face following error, I suggest you to download 64-bit Java from here. Make sure that you download 64-bit Java from following link: http://java.com/en/download/manual.jsp If already have Java 64-bit installed, you can continue with the installation as described in following image. Otherwise, install Java and start from with Step 1. As in my case, I already have 64-bit Java installed – and you won’t believe me when I say that the entire installation of NuoDB only took me around 90 seconds. Click on Finish to end to exit the installation. Step 4: Once the installation is successful, NuoDB will automatically open the following two tabs – Console and DevCenter — in your preferred browser. On the Console tab you can explore various components of the NuoDB solution, e.g. QuickStart, Admin, Explorer, Storefront and Samples. We will see various components and their usage in future blog posts. If you follow these steps in this post, which I have followed to install NuoDB, you will agree that the installation of NuoDB is extremely smooth and it was indeed a pleasure to install a database product with such ease. If you have installed other database products in the past, you will absolutely agree with me. So download NuoDB and install it today, and in tomorrow’s blog post I will take the installation to the next level.

• Why SQL Developer Rocks for the Advanced User Too

  - by thatjeffsmith

  While SQL Developer may be ‘perfect for Oracle beginners,’ that doesn’t preclude advanced and intermediate users from getting their fair share of toys! I’ve been working with Oracle since the 7.3.4 days, and I think it’s pretty safe to say that the WAY an ‘old timer’ uses a tool like SQL Developer is radically different than the ‘beginner.’ If you’ve been reluctant to use SQL Developer because it’s a GUI, give me a few minutes to try to convince you it’s worth a second (or third) look. 1. Help when you want it, and only when you want it One of the biggest gripes any user has with a piece of software is when said software can’t get out of it’s own way. When you’re typing in a word processor, sometimes you can do without the grammar and spelling checks, the offer to auto-complete your words, and all of the additional mark-up. This drives folks to programs like Notepad++ and vi. You can disable the code insight feature so you can type unmolested by SQL Developer’s attempt to auto-complete your object names. Now, if you happen to come across a long or hard to spell object name, you can still invoke the feature on demand using Ctrl+Spacebar Code Editor – Completion Insight – Enable Completion Auto-Popup (Keyword being Auto) 2. Automatic File Tracking SQL*Minus is nice. Vi is cool. Notepad++ has a lot of features I like. But not too many editors offer automatic logging of changes to your files without having to setup a source control system. I was doing some work on my login.sql. I’m not doing anything crazy, but seeing what I had done in previous iterations was helpful. Now imagine how nice it would be to have this available for your l,000+ line scripts! Track your scripts as they change, no setup required! 3. Extend the Functionality Know SQL and XML? Wish SQL Developer did JUST a little bit more? Build your own extensions. You can have custom context menus and object pages in just a few minutes. This is an example of lazy developers writing code that write code. 4. Get Your Money’s Worth You’ve licensed Enterprise Edition. You got your Diagnostic and Tuning packs. Now start using them! Not everyone has access to Enterprise Manager, especially developers. But that doesn’t mean they don’t need help with troubleshooting and optimizing poorly performing SQL statements. ASH, AWR, Real-Time SQL Monitoring and the SQL Tuning Advisor are built into the Reports and Worksheet. Yes you could make the package calls, but that’s a whole lot of typing, and I’d rather just get to the results. 5. Profile, Debug, & Unit Testing PLSQL An Interactive Development Environment (IDE) built by the same folks that own the programming language (Hello – Oracle PLSQL!) should be complete. It should ‘hug’ the developer and empower them to churn out programs that work, run fast, and are easy to maintain. Write it, test it, debug it, and tune it. When you’re running your programs and you just want to see the data that’s returned, that shouldn’t require any special settings or workaround to make it happen either. Magic! And a whole lot more… I could go on and talk about the support for things like DataPump, RMAN, and DBMS_SCHEDULER, but you’re experts and you’re plenty busy. If you think SQL Developer is falling short somewhere, I want you to let us know about it.

• SQL SERVER – Shard No More – An Innovative Look at Distributed Peer-to-peer SQL Database

  - by pinaldave

  There is no doubt that SQL databases play an important role in modern applications. In an ideal world, a single database can handle hundreds of incoming connections from multiple clients and scale to accommodate the related transactions. However the world is not ideal and databases are often a cause of major headaches when applications need to scale to accommodate more connections, transactions, or both. In order to overcome scaling issues, application developers often resort to administrative acrobatics, also known as database sharding. Sharding helps to improve application performance and throughput by splitting the database into two or more shards. Unfortunately, this practice also requires application developers to code transactional consistency into their applications. Getting transactional consistency across multiple SQL database shards can prove to be very difficult. Sharding requires developers to think about things like rollbacks, constraints, and referential integrity across tables within their applications when these types of concerns are best handled by the database. It also makes other common operations such as joins, searches, and memory management very difficult. In short, the very solution implemented to overcome throughput issues becomes a bottleneck in and of itself. What if database sharding was no longer required to scale your application? Let me explain. For the past several months I have been following and writing about NuoDB, a hot new SQL database technology out of Cambridge, MA. NuoDB is officially out of beta and they have recently released their first release candidate so I decided to dig into the database in a little more detail. Their architecture is very interesting and exciting because it completely eliminates the need to shard a database to achieve higher throughput. Each NuoDB database consists of at least three or more processes that enable a single database to run across multiple hosts. These processes include a Broker, a Transaction Engine and a Storage Manager.  Brokers are responsible for connecting client applications to Transaction Engines and maintain a global view of the network to keep track of the multiple Transaction Engines available at any time. Transaction Engines are in-memory processes that client applications connect to for processing SQL transactions. Storage Managers are responsible for persisting data to disk and serving up records to the Transaction Managers if they don’t exist in memory. The secret to NuoDB’s approach to solving the sharding problem is that it is a truly distributed, peer-to-peer, SQL database. Each of its processes can be deployed across multiple hosts. When client applications need to connect to a Transaction Engine, the Broker will automatically route the request to the most available process. Since multiple Transaction Engines and Storage Managers running across multiple host machines represent a single logical database, you never have to resort to sharding to get the throughput your application requires. NuoDB is a new pioneer in the SQL database world. They are making database scalability simple by eliminating the need for acrobatics such as sharding, and they are also making general administration of the database simpler as well.  Their distributed database appears to you as a user like a single SQL Server database.  With their RC1 release they have also provided a web based administrative console that they call NuoConsole. This tool makes it extremely easy to deploy and manage NuoDB processes across one or multiple hosts with the click of a mouse button. See for yourself by downloading NuoDB here.

• Combine the Address & Search Bars in Firefox

  - by Asian Angel

  The Search Bar in Firefox is very useful for finding additional information or images while browsing but the UI space it takes up can be frustrating at times. Now you can reclaim that UI space and still have access to all that searching goodness with the Foobar extension. Note: This is about the Foobar Firefox extension and not to be confused with Foobar2000 the open source music player. Before If you have the “Search Bar” displayed there is no doubt that it is taking up valuable space in your browser’s UI. What you need is the ability to reclaim that UI space and still have the same access to your search capability as before…no more sacrificing one for a gain with the other. After As soon as you have installed the extension you can see that the top part of your browser will look much sleeker without the “Search Bar” to clutter it up. The “Search Engine Icon” will now be visible inside of your “Address Bar” as seen here. You will be able to access the same “Search Engine Menu” as before by clicking on the “Search Engine Icon”. There are two display modes for search results (setting available in the “Options”). The first one shown here is “Simple Mode” where all results are in a condensed format. Notice that not only are there search suggestions but also “Bookmarks & History” listings as well. You can literally get the best of both when conducting a search. Note: The number of entries for search suggestions and bookmark/history listings can be adjusted higher or lower in the “Options”. The second one is “Rich Mode” where the results are shown with more details. Choose the “mode” that best suits your personal style. For our first example you can see the results when we conducted a quick search on “Windows 7” (using the first of the three offerings shown from Bing). Our second example was a search for “Flowers” using our Photobucket search engine. Once again nice results opened in a new tab for us. Options The options are easy to go through. It is really nice to be able to choose the number of results that you want displayed and the format that you want them shown in. Note: Changing the “Suggestion popup style” will require a browser restart to take effect. Conclusion If you love using the “Search Bar” in Firefox but want to reclaim the UI space then you will definitely want to add this extension to your browser. The ability to customize the number of results and choose the formatting make this extension even better.

• Creating shapes on the fly

  - by Bertrand Le Roy

  Most Orchard shapes get created from part drivers, but they are a lot more versatile than that. They can actually be created from pretty much anywhere, including from templates. One example can be found in the Layout.cshtml file of the ThemeMachine theme: WorkContext.Layout.Footer .Add(New.BadgeOfHonor(), "5"); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } What this is really doing is create a new shape called BadgeOfHonor and injecting it into the Footer global zone (that has not yet been defined, which in itself is quite awesome) with an ordering rank of "5". We can actually come up with something simpler, if we want to render the shape inline instead of sending it into a zone: @Display(New.BadgeOfHonor()) Now let's try something a little more elaborate and create a new shape for displaying a date and time: @Display(New.DateTime(date: DateTime.Now, format: "d/M/yyyy")) For the moment, this throws a "Shape type DateTime not found" exception because the system has no clue how to render a shape called "DateTime" yet. The BadgeOfHonor shape above was rendering something because there is a template for it in the theme: Themes/ThethemeMachine/Views/BadgeOfHonor.cshtml. We need to provide a template for our new shape to get rendered. Let's add a DateTime.cshtml file into our theme's Views folder in order to make the exception go away: Hi, I'm a date time shape. Now we're just missing one thing. Instead of displaying some static text, which is not very interesting, we can display the actual time that got passed into the shape's dynamic constructor. Those parameters will get added to the template's Model, so they are easy to retrieve: @(((DateTime)Model.date).ToString(Model.format)) Now that may remind you a little of WebForm's user controls. That's a fair comparison, except that these shapes are much more flexible (you can add properties on the fly as necessary), and that the actual rendering is decoupled from the "control". For example, any theme can override the template for a shape, you can use alternates, wrappers, etc. Most importantly, there is no lifecycle and protocol abstraction like there was in WebForms. I think this is a real improvement over previous attempts at similar things.

• Acr.ExtDirect &ndash; Part 1 &ndash; Method Resolvers

  - by Allan Ritchie

  One of the most important things of any open source libraries in my opinion is to be as open as possible while avoiding having your library become invasive to your code/business model design.  I personally could never stand marking my business and/or data access code with attributes everywhere.  XML also isn’t really a fav with too many people these days since it comes with a startup performance hit and requires runtime compiling.  I find that there is a whole ton of communication libraries out there currently requiring this (ie. WCF, RIA, etc).  Even though Acr.ExtDirect comes with its own set of attributes, you can piggy-back the [ServiceContract] & [OperationContract] attributes from WCF if you choose.  It goes beyond that though, there are 2 others “out-of-the-box” implementations – Convention based & XML Configuration.    Convention – I don’t actually recommend using this one since it opens up all of your public instance methods to remote execution calls. XML Configuration – This isn’t so bad but requires you enter all of your methods and there operation types into the Castle XML configuration & as I said earlier, XML isn’t the fav these days.   So what are your options if you don’t like attributes, convention, or XML Configuration?  Well, Acr.ExtDirect has its own extension base to give the API a list of methods and components to make available for remote execution.  1: public interface IDirectMethodResolver { 2:   3: bool IsServiceType(ComponentModel model, Type type); 4: string GetNamespace(ComponentModel model); 5: string[] GetDirectMethodNames(ComponentModel model); 6: DirectMethodType GetMethodType(ComponentModel model, MethodInfo method); 7: }   Now to implement our own method resolver:   1: public class TestResolver : IDirectMethodResolver { 2:   3: #region IDirectMethodResolver Members 4:   5: /// <summary> 6: /// Determine if you are calling a service 7: /// </summary> 8: /// <param name="model"></param> 9: /// <param name="type"></param> 10: /// <returns></returns> 11: public bool IsServiceType(ComponentModel model, Type type) { 12: return (type.Namespace == "MyBLL.Data"); 13: } 14:   15: /// <summary> 16: /// Return the calling name for the client side 17: /// </summary> 18: /// <param name="model"></param> 19: /// <returns></returns> 20: public string GetNamespace(ComponentModel model) { 21: return model.Name; 22: } 23:   24: public string[] GetDirectMethodNames(ComponentModel model) { 25: switch (model.Name) { 26: case "Products" : 27: return new [] { 28: "GetProducts", 29: "LoadProduct", 30: "Save", 31: "Update" 32: }; 33:   34: case "Categories" : 35: return new [] { 36: "GetProducts" 37: }; 38:   39: default : 40: throw new ArgumentException("Invalid type"); 41: } 42: } 43:   44: public DirectMethodType GetMethodType(ComponentModel model, MethodInfo method) { 45: if (method.Name.StartsWith("Save") || method.Name.StartsWith("Update")) 46: return DirectMethodType.FormSubmit; 47: 48: else if (method.Name.StartsWith("Load")) 49: return DirectMethodType.FormLoad; 50:   51: else 52: return DirectMethodType.Direct; 53: } 54:   55: #endregion 56: }   And there you have it, your own custom method resolver.  Pretty easy and pretty open ended!

• Exposed: Fake Social Marketing

  - by Mike Stiles

  Brands and marketers who want to build their social popularity on a foundation of lies are starting to face more of an uphill climb. Fake social is starting to get exposed, and there are a lot of emperors getting caught without any clothes. Facebook is getting ready to do a purge of “Likes” on Pages that were a result of bots, fake accounts, and even real users who were duped or accidentally Liked a Page. Most of those accidental Likes occur on mobile, where it’s easy for large fingers to hit the wrong space. Depending on the degree to which your Page has been the subject of such activity, you may see your number of Likes go down. But don’t sweat it, that’s a good thing. The social world has turned the corner and assessed the value of a Like. And the verdict is that a Like is valuable as an opportunity to build a real relationship with a real customer. Its value pales immensely compared to a user who’s actually engaged with the brand. Those fake Likes aren’t doing you any good. Huge numbers may once have impressed, but it’s not fooling anybody anymore. Facebook’s selling point to marketers is the ability to use a brand’s fans to reach friends of those fans. Consequently, there has to be validity and legitimacy to a fan count. Speaking of mobile, Trademob recently reported 40% of clicks are essentially worthless, because 22% of them are accidental (again with the fat fingers), while 18% are trickery. Publishers will but huge banner ads next to tiny app buttons to increase the odds of an accident. Others even hide a banner behind another to score 2 clicks instead of 1. Pontiflex and Harris Interactive last year found 47% of users were more likely to click a mobile ad accidentally than deliberately. Beyond that, hijacked devices are out there manipulating click data. But to what end for a marketer? What’s the value of a click on something a user never even saw? What’s the value of a seen but accidentally clicked ad if there’s no resulting transaction? Back to fake Likes, followers and views; they’re definitely for sale on numerous sites, none of which I’ll promote. $5 can get you 1,000 Twitter followers. You can even get followers targeted by interests. One site was set up by an unemployed accountant out of his house in England. He gets them from a wholesaler in Brooklyn, who gets them from a 19-year-old supplier in India. The unemployed accountant is making $10,000 a day. That means a lot of brands, celebrities and organizations are playing the fake social game, apparently not coming to grips with the slim value of the numbers they’re buying. But now, in addition to having paid good money for non-ROI numbers, there’s the embarrassment factor. At least a couple of sites have popped up allowing anyone to see just how many fake and inactive followers you have. Britain’s Fake Follower Check and StatusPeople are the two getting the most attention. Enter any Twitter handle and the results are there for all to see. Fake isn’t good, period. “Inactive” could be real followers, but if they’re real, they’re just watching, not engaging. If someone runs a check on your Twitter handle and turns up fake followers, does that mean you’re suspect or have purchased followers? No. Anyone can follow anyone, so most accounts will have some fakes. Even account results like Barack Obama’s (70% fake according to StatusPeople) and Lady Gaga’s (71% fake) don’t mean these people knew about all those fakes or initiated them. Regardless, brands should realize they’re now being watched, and users are judging the legitimacy of their social channels. Use one of any number of tools available to assess and clean out fake Likes and followers so that your numbers are as genuine as possible. And obviously, skip the “buying popularity” route of social marketing strategy. It doesn’t work and it gets you busted…a losing combination.

• Recover Lost Form Data in Firefox

  - by Asian Angel

  Have you ever filled in a text area or form in a webpage and something happens before you can finish it? If you like the idea of recovering that lost data then you will want to have a look at the Lazarus: Form Recovery extension for Firefox. Lazarus: Form Recovery in Action For our first example we chose the comment text box area for one of the articles here at the website. As you can see we were not finished typing in the whole comment yet… Notice the “Lazarus Icon” in the lower right corner. Note: We simulated accidental tab closures for our two examples. After getting our webpage opened up again all of our text was gone. Right clicking within the text area showed two options available…”Recover Text & Recover Form”. Notice that our lost text was listed as a “sub menu”…this could be extremely useful in matching up the appropriate text to the correct webpage if you had multiple tabs open before something happened. Click on the correct text listing to insert it. So easy to finish writing our comment without having to start from zero again. In our second example we chose the sign-up form page for the website. As before we were not finished filling in the form… Getting the webpage opened back up showed the same problem as before…all the entered text was lost. This time we right clicked in the browser window area and there was that wonderful “Recover Form Command” waiting to be used. One click and… All of our lost form data was back and we were able to finish filling in the form. For those who may be interested you can disable Lazarus: Form Recovery on individual websites using the “Context Menu” for the “Status Bar Icon” Options There are three sections in the options and you should take a quick look through them to make any desired modifications in how Lazarus: Form Recovery functions. The first “Options Area” focuses on display/access for the extension. The second “Options Area” allows you to expand the type of data retained, enable removal of data within a given time frame, set up a password, disable search indexing, and enable form data retention while in “Private Browsing Mode”. The third “Options Area” focuses on the Lazarus database itself. Conclusion If you have ever lost text area or form data before then you know how much time could be lost in starting over. Lazarus: Form Recovery helps provide a nice backup solution to get you up and running once again with a minimum of effort.

• Combining template method with strategy

  - by Mekswoll

  An assignment in my software engineering class is to design an application which can play different forms a particular game. The game in question is Mancala, some of these games are called Wari or Kalah. These games differ in some aspects but for my question it's only important to know that the games could differ in the following: The way in which the result of a move is handled The way in which the end of the game is determined The way in which the winner is determined The first thing that came to my mind to design this was to use the strategy pattern, I have a variation in algorithms (the actual rules of the game). The design could look like this: I then thought to myself that in the game of Mancala and Wari the way the winner is determined is exactly the same and the code would be duplicated. I don't think this is by definition a violation of the 'one rule, one place' or DRY principle seeing as a change in rules for Mancala wouldn't automatically mean that rule should be changed in Wari as well. Nevertheless from the feedback I got from my professor I got the impression to find a different design. I then came up with this: Each game (Mancala, Wari, Kalah, ...) would just have attribute of the type of each rule's interface, i.e. WinnerDeterminer and if there's a Mancala 2.0 version which is the same as Mancala 1.0 except for how the winner is determined it can just use the Mancala versions. I think the implementation of these rules as a strategy pattern is certainly valid. But the real problem comes when I want to design it further. In reading about the template method pattern I immediately thought it could be applied to this problem. The actions that are done when a user makes a move are always the same, and in the same order, namely: deposit stones in holes (this is the same for all games, so would be implemented in the template method itself) determine the result of the move determine if the game has finished because of the previous move if the game has finished, determine who has won Those three last steps are all in my strategy pattern described above. I'm having a lot of trouble combining these two. One possible solution I found would be to abandon the strategy pattern and do the following: I don't really see the design difference between the strategy pattern and this? But I am certain I need to use a template method (although I was just as sure about having to use a strategy pattern). I also can't determine who would be responsible for creating the TurnTemplate object, whereas with the strategy pattern I feel I have families of objects (the three rules) which I could easily create using an abstract factory pattern. I would then have a MancalaRuleFactory, WariRuleFactory, etc. and they would create the correct instances of the rules and hand me back a RuleSet object. Let's say that I use the strategy + abstract factory pattern and I have a RuleSet object which has algorithms for the three rules in it. The only way I feel I can still use the template method pattern with this is to pass this RuleSet object to my TurnTemplate. The 'problem' that then surfaces is that I would never need my concrete implementations of the TurnTemplate, these classes would become obsolete. In my protected methods in the TurnTemplate I could just call ruleSet.determineWinner(). As a consequence, the TurnTemplate class would no longer be abstract but would have to become concrete, is it then still a template method pattern? To summarize, am I thinking in the right way or am I missing something easy? If I'm on the right track, how do I combine a strategy pattern and a template method pattern? This is part of a homework assignment but I'm not looking to be gifted the answer, I have deliberately been very verbose in my question to show that I have thought about it before coming here to ask a question

• IIS not starting: The process cannot access the file because it is being used by another process

  - by Rick Strahl

  Ok, apparently a few people knew about this issue, but it is new to me and has caused me nearly an hour to track down today. What happened is that I’ve been working all day doing some final pre-deployment testing of several tools on my local dev machine. In the process I’ve been starting and stopping several IIS 7 Web sites. At some point I was done and just wanted to start my Default Web Site again and found this  little gem of an error message popping up: The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020) A lot of headless running around ensued after this, trying to figure out why IIS wouldn’t start. Oddly some sites started right up, others didn’t. I killed INetInfo, all worker processes, tried IISReset a million times and even rebooted – all to no avail. What gives? Skype, you evil Bastard! As it turns out the culprit is – drum roll please - Skype!  What, you may ask, does Skype have to do with IIS and Web Requests? It looks like recent versions of Skype have an option to run over Port 80 and 443 to allow running over corporate firewalls. Which is actually a nice feature that lets Skype work just about anywhere. What’s not so cool is that IIS fails to start up when another application is already using the same port that a Web site is mapped to. In the case of my dev site that’d be port 80 and Skype was hogging it. To fix this issue you can stop Skype from using port 80 and 443 which quickly fixes the problem. Or stop Skype. Duh! To permanently fix the problem in Skype find the option on the Options | Connection tab and uncheck the Use port 80/443 option: Oddly I haven’t run into this problem even though my setup hasn’t changed in quite some time. It appears that it’s bad startup timing that causes this problem to occur. Whatever the circumstance was, Skype somehow ended up starting before IIS.  If Skype is started after IIS has started it will automatically opt for other ports and not use port 80 and so there’s no problem. It’s easy to demonstrate this behavior if you’re looking for it: Stop IIS Stop Skype Start Skype and make a test call Start IIS And voila your error is ready for you! This really shouldn’t be a problem except that it would be really nice if IIS could give a more helpful error message when it can fire up a site because a port is blocked. “The process cannot access a file” is really not a very helpful error message in this scenario… I/O port / file ah what the heck it’s all the same to Windows. Right! I’ve run into this situation quite a bit with other, albeit more obvious applications like running Apache on the local machine for testing and then trying to run an IIS application. Same situation,  although it’s been a while – pre IIS 7 and I think previous versions of IIS actually gave more useful error messages for port blockages and that would be helpful. On the way to figuring this out I ran into some pretty humorous forum posts though with people ragging on why the hell you would be running IIS. Or Skype. The misinformed paranoia police out in full force so to say :-). It’ll be nice to start running IIS Express once Visual Studio 2010 SP1 gets released. Anyway, no surprise that Skype didn’t jump out at me as the culprit right away and I was left fumbling for a while until the Internet came to the rescue. I’m not the first to have found this for sure – I posted a message on Twitter and dozens of people replied they’d run into this before as well. Seems worth mentioning again though – since I’m sure to forget that this happened in a year from now when I hit that same error. Maybe I’ll even find this blog post to remind me…© Rick Strahl, West Wind Technologies, 2005-2011Posted in IIS7  Windows

• WebGrid Helper and Complex Types

  - by imran_ku07

      Introduction:           WebGrid helper makes it very easy to show tabular data. It was originally designed for ASP.NET Web Pages(WebMatrix) to display, edit, page and sort tabular data but you can also use this helper in ASP.NET Web Forms and ASP.NET MVC. When using this helper, sometimes you may run into a problem if you use complex types in this helper. In this article, I will show you how you can use complex types in WebGrid helper.       Description:             Let's say you need to show the employee data and you have the following classes,   public class Employee { public string Name { get; set; } public Address Address { get; set; } public List<string> ContactNumbers { get; set; } } public class Address { public string City { get; set; } }               The Employee class contain a Name, an Address and list of ContactNumbers. You may think that you can easily show City in WebGrid using Address.City, but no. The WebGrid helper will throw an exception at runtime if any Address property is null in the Employee list. Also, you cannot directly show ContactNumbers property. The easiest way to show these properties is to add some additional properties,   public Address NotNullableAddress { get { return Address ?? new Address(); } } public string Contacts { get { return string.Join("; ",ContactNumbers); } }               Now you can easily use these properties in WebGrid. Here is the complete code of this example,  @functions{ public class Employee { public Employee(){ ContactNumbers = new List<string>(); } public string Name { get; set; } public Address Address { get; set; } public List<string> ContactNumbers { get; set; } public Address NotNullableAddress { get { return Address ?? new Address(); } } public string Contacts { get { return string.Join("; ",ContactNumbers); } } } public class Address { public string City { get; set; } } } @{ var myClasses = new List<Employee>{ new Employee { Name="A" , Address = new Address{ City="AA" }, ContactNumbers = new List<string>{"021-216452","9231425651"}}, new Employee { Name="C" , Address = new Address{ City="CC" }}, new Employee { Name="D" , ContactNumbers = new List<string>{"045-14512125","21531212121"}} }; var grid = new WebGrid(source: myClasses); } @grid.GetHtml(columns: grid.Columns( grid.Column("NotNullableAddress.City", header: "City"), grid.Column("Name"), grid.Column("Contacts")))                    Summary:           You can use WebGrid helper to show tabular data in ASP.NET MVC, ASP.NET Web Forms and  ASP.NET Web Pages. Using this helper, you can also show complex types in the grid. In this article, I showed you how you use complex types with WebGrid helper. Hopefully you will enjoy this article too.

• Visual Studio Little Wonders: Quick Launch / Quick Access

  - by James Michael Hare

  Once again, in this series of posts I look at features of Visual Studio that may seem trivial, but can help improve your efficiency as a developer. The index of all my past little wonders posts can be found here. Well, my friends, this post will be a bit short because I’m in the middle of a bit of a move at the moment.  But, that said, I didn’t want to let the blog go completely silent this week, so I decided to add another Little Wonder to the list for the Visual Studio IDE. How often have you wanted to change an option or execute a command in Visual Studio, but can’t remember where the darn thing is in the menu, settings, etc.?  If so, Quick Launch in VS2012 (or Quick Access in VS2010 with the Productivity Power Tools extension) is just for you! Quick Launch / Quick Access – find a command or option quickly For those of you using Visual Studio 2012, Quick Launch is built right into the IDE at the top of the title bar, near the minimize, maximize, and close buttons: But do not despair if you are using Visual Studio 2010, you can get Quick Access from the Productivity Power Tools extension.  To do this, you can go to the extension manager: And then go to the gallery and search for Productivity Power Tools and install it.  If you don’t have VS2012 yet, then the Productivity Power Tools is the next best thing.  This extension updates VS2010 with features such as Quick Access, the Solution Navigator, searchable Add Reference Dialog, better tab wells, etc.  I highly recommend it! But back to the topic at hand!  In VS2012 Quick Launch is built into the IDE and can be accessed by clicking in the Quick Launch area of the title bar, or by pressing CTRL+Q.  If you have VS2010 with the PPT installed, though, it is called Quick Access and is accessible through View –> Quick Access: Regardless of which IDE you are using, the feature behaves mostly the same.  It allows you to search all of Visual Studio’s commands and options for a particular topic.  For example, let’s say you want to change from tabs to tabs expanded to spaces, but don’t remember where that option is buried.  You can bring up Quick Launch / Quick Access and type in “tabs”: And it brings up a list of all options on tabs, you can then choose the one appropriate to you and click on it and it will take you right there! A lot easier than diving through the options tree to find what you are looking for!  It also works on menu commands, for example if you can’t remember how to open the Output window: It shows you the menu items that will get you to the Output window, and (if applicable) the keyboard shortcuts.  Again, clicking on one of these will perform the action for you as well. There are also some tasks you can perform directly from Quick Launch / Quick Access.  For example, perhaps you are one of those people who like to have the line numbers in your editor (I do), so let’s bring up Quick Launch / Quick Access and type “line numbers”: And let’s select Turn Line Numbers On, and now our editor looks like: And Voila!  We have line numbers in VS2010.  You can do this in VS2012 too, but it takes you to the option settings instead of directly turning them off and on.  There are bound to be differences between the way the two editors organize settings and commands, but you get the point. So, as you can see, the Quick Launch / Quick Access feature in Visual Studio makes it easy to jump right to the options, commands, or tasks you are interested in without all the digging. Summary An IDE as powerful as Visual Studio has so many options and commands that it can be confusing to remember how to find and invoke them.  Quick Launch (Quick Access in VS2010 with Productivity Power Tools extension) is a quick and handy way to jump to any of these options, commands, or tasks quickly without having to remember in what menu or screen they are buried!  Technorati Tags: C#,CSharp,.NET,Little Wonders,Visual Studio,Quick Access,Quick Launch

• How to Use Sparklines in Excel 2010

  - by DigitalGeekery

  One of the cool features of Excel 2010 is the addition of Sparklines. A Sparkline is basically a little chart displayed in a cell representing your selected data set that allows you to quickly and easily spot trends at a glance. Inserting Sparklines on your Spreadsheet You will find the Sparklines group located on the Insert tab.   Select the cell or cells where you wish to display your Sparklines. Select the type of Sparkline you’d like to add to your spreadsheet. You’ll notice there are three types of Sparklines, Line, Column, and Win/Loss. We’ll select Line for our example. A Create Sparklines pops up and will prompt you to enter a Data Range you are using to create the Sparklines. You’ll notice that the location range (the range where the Sparklines will appear) is already filled in. You can type in the data range manually, or click and drag with your mouse across to select the data range. This will auto-fill the data range for you. Click OK when you are finished.   You will see your Sparklines appear in the desired cells.   Customizing Sparklines Select the one of more of the Sparklines to reveal the Design tab. You can display certain value points like high and low points, negative points, and first and last points by selecting the corresponding options from the Show group. You can also mark all value points by selecting  Markers. Select your desired Sparklines and click one of the included styles from the Style group on the Design tab. Click the down arrow on the lower right corner of the box to display additional pre-defined styles…   or select Sparkline Color or Marker Color options to fully customize your Sparklines. The Axis options allow additional options such as Date Axis Type, Plotting Data Left to Right, and displaying an axis point to represent the zero line in your data with Show Axis. Column Sparklines Column Sparklines display your data in individual columns as opposed to the Line view we’ve been using for our examples. Win/Loss Sparklines Win/Loss shows a basic positive or negative representation of your data set.   You can easily switch between different Sparkline types by simply selecting the current cells (individually or the entire group), and then clicking the desired type on the Design tab. For those that may be more visually oriented, Sparklines can be a wonderful addition to any spreadsheet. Are you just getting started with Office 2010?

• Share Folders & Files Between Vista and XP Machines

  - by Mysticgeek

  Since Microsoft has three operating systems in use, chances are you’ll find yourself needing to share files between XP, Vista, Windows 7, or some combination of the three. Here we take a look at sharing between a Vista and XP on your home network. Share Without Password Protected Sharing If you’re not worried about who’s accessing the files and folders, the easiest method is to disable Password Protected Sharing. So on the Vista machine open Network and Sharing Center. Under Sharing and Discovery make sure Network Discovery, File Sharing, and, Public Folder Sharing are turned on. Also turn off Password Protected Sharing… Now go into the Vista Public folder, located in C:\Users\Public, and add what you want to share or create a new folder. In this example we created a new folder called XP_Share and added some files to it. On the XP machine go into My Network Places and under Network Tasks click on View Workgroup Computers. Now you’ll see all of the computers on your network which should be part of the same Workgroup. Here we need to double-click on the Vista computer. And there we go…no password to enter so we can access the XP_Share folder or anything else that is located in the Public folder. Share with Password Protected Sharing If you want to keep Password Protected Sharing turned on, then we need to do things a little different. When it’s turned on and you try to access the Vista machine from XP, you’re prompted for a password, and no matter what you think the credentials are, you can’t get access…very annoying. So what we need to do is add the XP Machine as a user. Right-click on Computer from the Start Menu or desktop icon and select Manage from the context menu. The Computer Management screen opens up and you want to expand Local Users and Groups, then the Users folder. Then right-click any open area an select New User. Now create a new user name and password, you can also fill in the other fields if you want. Then make sure to uncheck User must change password at next logon and check the box next to Password never expires. Click the Create button and close out of the New User screen. You’ll then see the new user we created in the list and you can close out of the Computer Management window. Now back on the XP computer when you double-click on the Vista machine, your prompted to log in. Just type in the username and password you just created. Now you’ll have access to the Public folder contents. Set up Sharing on XP If you want to access a shared folder from the Vista computer located on the XP machine, it’s the same process in reverse. On the XP computer in Shared Documents, right-click on the folder you want to share and select Sharing and Security. Then select the radio button next to Share this folder and click Ok. Go into Computer Management and create a new user… Now from the Vista machine double click on the XP machine icon, enter the password, then access the folders and files you need. If you have multiple versions of Windows on your home network, you’ll now be able to access files and folders from each of them.

• UEFI Dual-Boot - Ubuntu 12.04.3 + Windows 8.1 (One GPT HDD)

  - by swafbrother

  UEFI Dual-Boot - Ubuntu 12.04.3 + Windows 8.1 (One GPT HDD) Hello, I'm having trouble setting up a dual-boot (Ubuntu 12.04 LTS and Windows 8.1) in my ASUS K55VM laptop's hard drive disk (500 GB). I was mostly following tutorials for doing this, but at some point something has gone wrong. Up to now, I have followed these steps: I formatted my HDD into GPT. I clean-installed Windows 8.1. I didn't prevent Windows from choosing the partitions to use and it created these partitions: A Recovery partition (sda1). An EFI System Partition (sda2). A Microsoft Reserved Partition (sda3). A Windows Data Partition or C drive (sda4). I reduced the Windows Data Partition via Windows' Disk Management. I made a bootable USB Stick with Ubuntu 12.04 LTS from ISO, using Universal USB Installer. I created these partitions for Ubuntu: A Boot partition, mounted at /boot (sda5). A Root partition, mounted at / (sda6). A Swap partition (sda7). In Device for boot loader installation I chose: /dev/sda. Then, when I rebooted, it went straight into Ubuntu. So I installed Boot-Repair, and clicked on Recommended Repair. It automatically did its job without asking for anything. I rebooted and Grub showed up, with a lot of options. At this point I had a decent dual-boot setup; Ubuntu and both Windows entries worked fine: Ubuntu. Windows Boot UEFI Loader. Windows UEFI bkpbootmgfw.efi. I executed this command: sudo grub-install --force /dev/sda5. Then I tried to make Windows 8.1's Boot Manager the main boot manager, so that I could choose which OS to boot into from a menu. I downloaded EasyBCD on Windows. It showed 2 Ubuntu entries and 1 Windows entry. I went into BCD Deployment tab and clicked on Write MBR. At this point, I went into BIOS and made Windows Boot Manager the first boot option. When I rebooted, I got a black screen with the message efidisk read error, and then (I guess) it switched to the next boot option, which is Ubuntu, resulting in Grub showing up. From Grub, Ubuntu entry is working and so are both Windows entries. If I choose Ubuntu, it normally boots into Ubuntu. But if I choose Windows, it goes into Windows' boot manager. In Windows' boot manager, a menu shows up: Ubuntu. Ubuntu. Windows 8.1. If I choose Windows, it boots into Windows without any problem. If I choose Ubuntu, it boots into Grub (back to step 14). Here's my BootInfo Summary: http://paste.ubuntu.com/6698171/ Windows Boot Manager is clearly not working as expected; I can't directly boot into it and I can't boot into it from BIOS either (efidisk read error again). If I want to boot into Windows I need to boot into Grub first, which is the opposite of what I wanted. I need help at this point. What is the best thing I can do? Is there a more reliable and/or simpler way of acomplishing a satisfying dual-boot for this situation? Can someone provide a way for going back to step 8, where I had a more efficient dual-boot setup? If only I could undo what I did with Easy BCD and skip Windows' Boot Menu... Can someone provide a way to fix this mess? Thanks in advance and sorry for the length of this, I wanted to be exhaustive.

• Problem with script substitution when running script

  - by tucaz

  Hi! I'm new to Linux so this probably should be an easy fix, but I cannot see it. I have a script downloaded from official sources that is used to install additional tools for fsharp but it gives me a syntax error when running it. I tried to replace ( and ) by { and } but eventually it lead me to another error so I think this is not the problem since the script works for everybody. I read some articles that say that my bash version maybe is not the right one. I'm using Ubuntu 10.10 and here is the error: install-bonus.sh: 28: Syntax error: "(" unexpected (expecting "}") And this is line 27, 28 and 29: { declare -a DIRS=("${!3}") FILE=$2 And the full script: #! /bin/sh -e PREFIX=/usr BIN=$PREFIX/bin MAN=$PREFIX/share/man/man1/ die() { echo "$1" &2 echo "Installation aborted." &2 exit 1 } echo "This script will install additional material for F# including" echo "man pages, fsharpc and fsharpi scripts and Gtk# support for F#" echo "Interactive (root access needed)" echo "" # ------------------------------------------------------------------------------ # Utility function that searches specified directories for a specified file # and if the file is not found, it asks user to provide a directory RESULT="" searchpaths() { declare -a DIRS=("${!3}") FILE=$2 DIR=${DIRS[0]} for TRYDIR in ${DIRS[@]} do if [ -f $TRYDIR/$FILE ] then DIR=$TRYDIR fi done while [ ! -f $DIR/$FILE ] do echo "File '$FILE' was not found in any of ${DIRS[@]}.
