  • Trust: A New Line of Business

    - by ruth.donohue
    What do you think are the key factors in building and maintaining your company's reputation... Innovation? Price? Surprisingly, according to the recent 2010 Edelman Trust Barometer, survey respondents in the US valued transparency of business practices as well as company trustworthiness as the two most important factors influencing corporate reputation. What is trust? It's the confidence in a company's ability to do what is right for all its stakeholders -- shareholders, customers, employees, and the broader society at large -- and not just shareholders. Trust is an increasingly important component to maintaining your company's reputation and brand, and Western countries have seen an increase in global trust. Global businesses headquartered in the United States in particular have seen an 18 point boost to 54 percent in global trust. Whether this uptick represents the start of a new trend or a mere blip in the barometer remains to be seen. The Edelman report notes that the increase is "tenuous" as people expect companies to return to "business as usual" after the economy rebounds. This warning underscores the need for companies to continue engaging in open and frequent communications and business practices with its stakeholders across multiple channels and view trust as a "new line of business" to cultivate.

  • C#.NET vs VB.NET, Which language is better?

    Features I cannot say any language good or bad as long as it's compiler can produce MSIL can run under .NET CLR. If someone says C# has more futures, you can understand that those new features are of C# compiler but not .NET, because if C# has a specific future then CLR cannot understand them. So the new features of C# will have to convert to the code understood by CLR eventually. that means the new features are developed for C# compiler basically to facilitates the developer to write their code in better way. so that means no difference in feature list between C# and VB.NET if you think in CLR perspective. Ease of writing Code I feel writing code in C# is easy, because my background is C and C++, Java, syntaxes very are similar. I assume most developers feel the same. Readability But some people say VB.NET code most readable for the members who are from non technical background, because keywords are generally in English rather special charectors. No of Projects in Market I assume 80 percent of market uses C# in their .NET development. for example in my company many projects are there .nET and all are using C#. Productivity & Experience though the feature list is same, generally developers wants to write code in their familiar languages. because it increase the productivity. Hope this helps to choose the language which suits for you. span.fullpost {display:none;}

  • Oracle VM Blade Cluster Reference Configuration

    - by Ferhat Hatay
    Today we are happy to announce the availability of the Oracle VM blade cluster reference configuration for Sun Blade 6000 modular systems.  The new Oracle VM blade cluster reference configuration can help reduce the time to deploy virtual infrastructure by up to 98 percent when compared to multi-vendor configurations. Oracle's virtualization strategy is to simplify the deployment, management, and support of the enterprise stack from application to disk. The Oracle VM blade cluster reference configuration is a single-vendor solution that addresses every layer of the virtualization stack with Oracle hardware and software components. It enables quick and easy deployment of the virtualized infrastructure using components that have been tested together and are all supported together by one vendor — Oracle. All components listed in the reference configuration have been tested together by Oracle, reducing the need for customer testing and the time-consuming and complex effort of designing and deploying a stable configuration. Benefitting from pre-installed Oracle VM Server for x86 software on Oracle’s highly scalable and reliable Sun Blade servers with built-in networking and Oracle’s Sun ZFS Storage Appliance product line, the configuration provides high availability via the blade cluster as well as a documented best practice guide that helps reduce deployment time and cost for customers implementing highly virtualized applications or private cloud Infrastructure as a Service (IaaS) architectures. To further support easier, faster and lower-cost deployments, Oracle Linux, Oracle Solaris and Oracle VM are available for pre-install on select Sun x86 systems, and Oracle VM Templates are available for download for Oracle Applications, Oracle Fusion Middleware, Oracle Database, Oracle Real Application Clusters, and many other Oracle products. Key benefits of the Oracle VM blade cluster reference configuration include: Faster time to value – Begin deploying applications immediately because the optimized software stack is pre-configured for best practices and is ready-to-run on the recommended hardware platforms. Reduced deployment cost and risk – The entire hardware and software stack has been tested and is supported together by Oracle. Elastic scalability – As capacity needs grow, the system can be easily scaled in multiple dimensions with the ability to add compute, storage, and networking resources independently. For more information, see: Oracle white paper: Accelerating deployment of virtualized infrastructures with the Oracle VM blade cluster reference configuration Oracle technical white paper: Best Practices and Guidelines for Deploying the Oracle VM Blade Cluster Reference Configuration

  • eLearning event on HTML5 for Mobile with jQuery Mobile

    - by Wallym
    I'll be doing an eLearning event on HTML5 for Mobile with jQuery Mobile. There will also be a few items sprinkled in on ASP.NET Razor. Mobile development is a hot item. Customers are buying iPhones, iPads, Android devices, and many other mobile computing devices at an ever increasing record pace. Devices based on iOS and Android are nearly 80 percent of the marketplace. RIM continues to be dominant in the business area across the world. Nokia's growth with Windows Phone will grow on a worldwide basis. At the same time, clearly web development is a tremendous driver of applications, both on the public Internet and on private networks. How can developers target these various mobile platforms with web technologies? Developers can write web applications that take advantage of each mobile platform, but that is a lot of work. Into this space, the jQuery Mobile framework was developed. This eLearning series will provide an overview of mobile web development with jQuery Mobile, a detailed look at what the jQuery Mobile framework provides for us, how we can customize jQuery Mobile, and how we can use jQuery Mobile inside of ASP.NET.Link: http://elearning.left-brain.com/event/mobile-web-development

  • SQL Spatial: Getting “nearest” calculations working properly

    - by Rob Farley
    If you’ve ever done spatial work with SQL Server, I hope you’ve come across the ‘nearest’ problem. You have five thousand stores around the world, and you want to identify the one that’s closest to a particular place. Maybe you want the store closest to the LobsterPot office in Adelaide, at -34.925806, 138.605073. Or our new US office, at 42.524929, -87.858244. Or maybe both! You know how to do this. You don’t want to use an aggregate MIN or MAX, because you want the whole row, telling you which store it is. You want to use TOP, and if you want to find the closest store for multiple locations, you use APPLY. Let’s do this (but I’m going to use addresses in AdventureWorks2012, as I don’t have a list of stores). Oh, and before I do, let’s make sure we have a spatial index in place. I’m going to use the default options. CREATE SPATIAL INDEX spin_Address ON Person.Address(SpatialLocation); And my actual query: WITH MyLocations AS (SELECT * FROM (VALUES ('LobsterPot Adelaide', geography::Point(-34.925806, 138.605073, 4326)),                        ('LobsterPot USA', geography::Point(42.524929, -87.858244, 4326))                ) t (Name, Geo)) SELECT l.Name, a.AddressLine1, a.City, s.Name AS [State], c.Name AS Country FROM MyLocations AS l CROSS APPLY (     SELECT TOP (1) *     FROM Person.Address AS ad     ORDER BY l.Geo.STDistance(ad.SpatialLocation)     ) AS a JOIN Person.StateProvince AS s     ON s.StateProvinceID = a.StateProvinceID JOIN Person.CountryRegion AS c     ON c.CountryRegionCode = s.CountryRegionCode ; Great! This is definitely working. I know both those City locations, even if the AddressLine1s don’t quite ring a bell. I’m sure I’ll be able to find them next time I’m in the area. But of course what I’m concerned about from a querying perspective is what’s happened behind the scenes – the execution plan. This isn’t pretty. It’s not using my index. It’s sucking every row out of the Address table TWICE (which sucks), and then it’s sorting them by the distance to find the smallest one. It’s not pretty, and it takes a while. Mind you, I do like the fact that it saw an indexed view it could use for the State and Country details – that’s pretty neat. But yeah – users of my nifty website aren’t going to like how long that query takes. The frustrating thing is that I know that I can use the index to find locations that are within a particular distance of my locations quite easily, and Microsoft recommends this for solving the ‘nearest’ problem, as described at http://msdn.microsoft.com/en-au/library/ff929109.aspx. Now, in the first example on this page, it says that the query there will use the spatial index. But when I run it on my machine, it does nothing of the sort. I’m not particularly impressed. But what we see here is that parallelism has kicked in. In my scenario, it’s split the data up into 4 threads, but it’s still slow, and not using my index. It’s disappointing. But I can persuade it with hints! If I tell it to FORCESEEK, or use my index, or even turn off the parallelism with MAXDOP 1, then I get the index being used, and it’s a thing of beauty! Part of the plan is here: It’s massive, and it’s ugly, and it uses a TVF… but it’s quick. The way it works is to hook into the GeodeticTessellation function, which is essentially finds where the point is, and works out through the spatial index cells that surround it. This then provides a framework to be able to see into the spatial index for the items we want. You can read more about it at http://msdn.microsoft.com/en-us/library/bb895265.aspx#tessellation – including a bunch of pretty diagrams. One of those times when we have a much more complex-looking plan, but just because of the good that’s going on. This tessellation stuff was introduced in SQL Server 2012. But my query isn’t using it. When I try to use the FORCESEEK hint on the Person.Address table, I get the friendly error: Msg 8622, Level 16, State 1, Line 1 Query processor could not produce a query plan because of the hints defined in this query. Resubmit the query without specifying any hints and without using SET FORCEPLAN. And I’m almost tempted to just give up and move back to the old method of checking increasingly large circles around my location. After all, I can even leverage multiple OUTER APPLY clauses just like I did in my recent Lookup post. WITH MyLocations AS (SELECT * FROM (VALUES ('LobsterPot Adelaide', geography::Point(-34.925806, 138.605073, 4326)),                        ('LobsterPot USA', geography::Point(42.524929, -87.858244, 4326))                ) t (Name, Geo)) SELECT     l.Name,     COALESCE(a1.AddressLine1,a2.AddressLine1,a3.AddressLine1),     COALESCE(a1.City,a2.City,a3.City),     s.Name AS [State],     c.Name AS Country FROM MyLocations AS l OUTER APPLY (     SELECT TOP (1) *     FROM Person.Address AS ad     WHERE l.Geo.STDistance(ad.SpatialLocation) < 1000     ORDER BY l.Geo.STDistance(ad.SpatialLocation)     ) AS a1 OUTER APPLY (     SELECT TOP (1) *     FROM Person.Address AS ad     WHERE l.Geo.STDistance(ad.SpatialLocation) < 5000     AND a1.AddressID IS NULL     ORDER BY l.Geo.STDistance(ad.SpatialLocation)     ) AS a2 OUTER APPLY (     SELECT TOP (1) *     FROM Person.Address AS ad     WHERE l.Geo.STDistance(ad.SpatialLocation) < 20000     AND a2.AddressID IS NULL     ORDER BY l.Geo.STDistance(ad.SpatialLocation)     ) AS a3 JOIN Person.StateProvince AS s     ON s.StateProvinceID = COALESCE(a1.StateProvinceID,a2.StateProvinceID,a3.StateProvinceID) JOIN Person.CountryRegion AS c     ON c.CountryRegionCode = s.CountryRegionCode ; But this isn’t friendly-looking at all, and I’d use the method recommended by Isaac Kunen, who uses a table of numbers for the expanding circles. It feels old-school though, when I’m dealing with SQL 2012 (and later) versions. So why isn’t my query doing what it’s supposed to? Remember the query... WITH MyLocations AS (SELECT * FROM (VALUES ('LobsterPot Adelaide', geography::Point(-34.925806, 138.605073, 4326)),                        ('LobsterPot USA', geography::Point(42.524929, -87.858244, 4326))                ) t (Name, Geo)) SELECT l.Name, a.AddressLine1, a.City, s.Name AS [State], c.Name AS Country FROM MyLocations AS l CROSS APPLY (     SELECT TOP (1) *     FROM Person.Address AS ad     ORDER BY l.Geo.STDistance(ad.SpatialLocation)     ) AS a JOIN Person.StateProvince AS s     ON s.StateProvinceID = a.StateProvinceID JOIN Person.CountryRegion AS c     ON c.CountryRegionCode = s.CountryRegionCode ; Well, I just wasn’t reading http://msdn.microsoft.com/en-us/library/ff929109.aspx properly. The following requirements must be met for a Nearest Neighbor query to use a spatial index: A spatial index must be present on one of the spatial columns and the STDistance() method must use that column in the WHERE and ORDER BY clauses. The TOP clause cannot contain a PERCENT statement. The WHERE clause must contain a STDistance() method. If there are multiple predicates in the WHERE clause then the predicate containing STDistance() method must be connected by an AND conjunction to the other predicates. The STDistance() method cannot be in an optional part of the WHERE clause. The first expression in the ORDER BY clause must use the STDistance() method. Sort order for the first STDistance() expression in the ORDER BY clause must be ASC. All the rows for which STDistance returns NULL must be filtered out. Let’s start from the top. 1. Needs a spatial index on one of the columns that’s in the STDistance call. Yup, got the index. 2. No ‘PERCENT’. Yeah, I don’t have that. 3. The WHERE clause needs to use STDistance(). Ok, but I’m not filtering, so that should be fine. 4. Yeah, I don’t have multiple predicates. 5. The first expression in the ORDER BY is my distance, that’s fine. 6. Sort order is ASC, because otherwise we’d be starting with the ones that are furthest away, and that’s tricky. 7. All the rows for which STDistance returns NULL must be filtered out. But I don’t have any NULL values, so that shouldn’t affect me either. ...but something’s wrong. I do actually need to satisfy #3. And I do need to make sure #7 is being handled properly, because there are some situations (eg, differing SRIDs) where STDistance can return NULL. It says so at http://msdn.microsoft.com/en-us/library/bb933808.aspx – “STDistance() always returns null if the spatial reference IDs (SRIDs) of the geography instances do not match.” So if I simply make sure that I’m filtering out the rows that return NULL… …then it’s blindingly fast, I get the right results, and I’ve got the complex-but-brilliant plan that I wanted. It just wasn’t overly intuitive, despite being documented. @rob_farley

  • Welcome Relief

    - by michael.seback
    Government organizations are experiencing unprecedented demand for social services. The current economy continues to put immense stress on social service organizations. Increased need for food assistance, employment security, housing aid and other critical services is keeping agencies busier than ever. ... The Kansas Department of Labor (KDOL) uses Oracle's social services solution in its employment security program. KDOL has used Siebel Customer Relationship Management (CRM) for nearly a decade, and recently purchased Oracle Policy Automation to improve its services even further. KDOL implemented Siebel CRM in 2002, and has expanded its use of it over the years. The agency started with Siebel CRM in the call center and later moved it into case management. Siebel CRM has been a strong foundation for KDOL in the face of rising demand for unemployment benefits, numerous labor-related law changes, and an evolving IT environment. ... The result has been better service for constituents. "It's really enabled our staff to be more effective in serving clients," said Hubka. That's a trend the department plans to continue. "We're 100 percent down the path of Siebel, in terms of what we're doing in the future," Hubka added. "Their vision is very much in line with what we're planning on doing ourselves." ... Community Services is the leading agency responsible for the safety and well-being of children and young people within Australia's New South Wales (NSW) Government. Already a longtime Oracle Case Management user, Community Services recently implemented Oracle Policy Automation to ensure accurate, consistent decisions in the management of child safety. "Oracle Policy Automation has helped to provide a vehicle for the consistent application of the Government's 'Keep Them Safe' child protection action plan," said Kerry Holling, CIO for Community Services. "We believe this approach is a world-first in the structured decisionmaking space for child protection and we believe our department is setting an example that other child protection agencies will replicate." ...

  • MSDN article on jQuery Mobile

    - by Wallym
    My article on jQuery Mobile has been published.  Please check it out.There’s no doubt about it. Wherever developers look and whoever they talk to, mobile is at the top of the list. Talk to a C-level executive, and the conversation turns to mobile, and the question “How do I get me some of that?” comes up. Talk to other developers, and they tell you they’re targeting mobile devices. Mobile has become a big deal as smartphones have taken hold in the consumer marketplace.In the years leading up to the current focus on mobile applications and devices, Web developers have been adding more and more client-side functionality to their applications. You can see this in the use of client-side JavaScript libraries like jQuery.With the growth of the market for mobile devices, the ability to create applications that run across platforms is very important for developers and for businesses that are trying to keep their expenses in check. There are a set of applications, mostly in the area of content consumption (think Amazon.com), that run well in a mobile Web browser. Unfortunately, there are differences between Web browsers on various mobile devices. The goal of the recently introduced jQuery Mobile (jQM) library is to provide cross-browser support to allow developers to build applications that can run across the various mobile Web browsers and provide the same—or at least a very similar—user interface.The jQuery Mobile library was introduced in an alpha release in the fall of 2010 and released to manufacturing in November 2011. At the time of this writing, the current version of jQuery Mobile is 1.1.1. By the time you read this, jQuery Mobile will almost certainly have reached version 1.2.0. The library has been embraced by Microsoft, Adobe and other companies for mobile Web development. In August 2011, jQM had 32 percent market share compared with other mobile JavaScript frameworks such as iWebKit and jQTouch. This market share is impressive given that it started from zero little more than 12 months ago, and the 1.0 release is the first officially supported release.

  • IT Optimization Plan Pays Off For UK Retailer

    - by Brian Dayton
    I caught this article in ComputerworldUK yesterday. The headline talks about UK-based supermarket chain Morrisons is increasing their IT spend...OK, sounds good. Even nicer that Oracle is a big part of that. But what caught my eye were three things: 1) Morrison's truly has a long term strategy for IT. In this case, modernizing and optimizing how they use IT for business advantage.   2) Even in a tough economic climate, Morrison's views IT investments as contributing to and improving the bottom line. Specifically, "The investment in IT contributed to a 21 percent increase in Morrison's underlying profit.."   3) The phased, 3-year "Optimization Plan" took a holistic approach to their business--from CRM and Supply Chain systems to the underlying application infrastructure. On the infrastructure front, adopting a more flexible Service-Oriented Architecture enabled them to be more agile and adapt their business and Identity Management helped with sometimes mundane (but costly) issues like lost passwords and being able to document who has access to what.   Things don't always turn out so rosy. And I know it was a long and difficult process...but it's nice to see a happy ending every once in a while.

  • Restoring factory image of HP Laptop

    - by Ahmed
    I use a HP G62. I am unable to use my recovery disk to restore to factory settings. I had no problems earlier until I created an additional partition which I hear might have changed my hard disk to dynamic. How do I get back to 'normal'? I don't mind formatting the disk. I just want my factory OS back. .............. i get an error message at about 69 percent telling me that the restoration process failed. I'm using the factory image disks i created using the hp recovery manager. I have tried formating the hard drive clean and then restoring woth the cd, it didn't work. I was always able to restore before i created that partition.

  • How do I manage the technical debate over WCF vs. Web API?

    - by Saeed Neamati
    I'm managing a team of like 15 developers now, and we are stuck at a point on choosing the technology, where the team is broken into two completely opposite teams, debating over usage of WCF vs. Web API. Team A which supports usage of Web API, brings forward these reasons: Web API is just the modern way of writing services (Wikipedia) WCF is an overhead for HTTP. It's a solution for TCP, and Net Pipes, and other protocols WCF models are not POCO, because of [DataContract] & [DataMember] and those attributes SOAP is not as readable and handy as JSON SOAP is an overhead for network compared to JSON (transport over HTTP) No method overloading Team B which supports the usage of WCF, says: WCF supports multiple protocols (via configuration) WCF supports distributed transactions Many good examples and success stories exist for WCF (while Web API is still young) Duplex is excellent for two-way communication This debate is continuing, and I don't know what to do now. Personally, I think that we should use a tool only for its right place of usage. In other words, we'd better use Web API, if we want to expose a service over HTTP, but use WCF when it comes to TCP and Duplex. By searching the Internet, we can't get to a solid result. Many posts exist for supporting WCF, but on the contrary we also find people complaint about it. I know that the nature of this question might sound arguable, but we need some good hints to decide. We're stuck at a point where choosing a technology by chance might make us regret it later. We want to choose with open eyes. Our usage would be mostly for web, and we would expose our services over HTTP. In some cases (say 5 to 10 percent) we might need distributed transactions though. What should I do now? How do I manage this debate in a constructive way?

  • Tutorial: Getting Started with the NoSQL JavaScript / Node.js API for MySQL Cluster

    - by Mat Keep
    Tutorial authored by Craig Russell and JD Duncan  The MySQL Cluster team are working on a new NoSQL JavaScript connector for MySQL. The objectives are simplicity and high performance for JavaScript users: - allows end-to-end JavaScript development, from the browser to the server and now to the world's most popular open source database - native "NoSQL" access to the storage layer without going first through SQL transformations and parsing. Node.js is a complete web platform built around JavaScript designed to deliver millions of client connections on commodity hardware. With the MySQL NoSQL Connector for JavaScript, Node.js users can easily add data access and persistence to their web, cloud, social and mobile applications. While the initial implementation is designed to plug and play with Node.js, the actual implementation doesn't depend heavily on Node, potentially enabling wider platform support in the future. Implementation The architecture and user interface of this connector are very different from other MySQL connectors in a major way: it is an asynchronous interface that follows the event model built into Node.js. To make it as easy as possible, we decided to use a domain object model to store the data. This allows for users to query data from the database and have a fully-instantiated object to work with, instead of having to deal with rows and columns of the database. The domain object model can have any user behavior that is desired, with the NoSQL connector providing the data from the database. To make it as fast as possible, we use a direct connection from the user's address space to the database. This approach means that no SQL (pun intended) is needed to get to the data, and no SQL server is between the user and the data. The connector is being developed to be extensible to multiple underlying database technologies, including direct, native access to both the MySQL Cluster "ndb" and InnoDB storage engines. The connector integrates the MySQL Cluster native API library directly within the Node.js platform itself, enabling developers to seamlessly couple their high performance, distributed applications with a high performance, distributed, persistence layer delivering 99.999% availability. The following sections take you through how to connect to MySQL, query the data and how to get started. Connecting to the database A Session is the main user access path to the database. You can get a Session object directly from the connector using the openSession function: var nosql = require("mysql-js"); var dbProperties = {     "implementation" : "ndb",     "database" : "test" }; nosql.openSession(dbProperties, null, onSession); The openSession function calls back into the application upon creating a Session. The Session is then used to create, delete, update, and read objects. Reading data The Session can read data from the database in a number of ways. If you simply want the data from the database, you provide a table name and the key of the row that you want. For example, consider this schema: create table employee (   id int not null primary key,   name varchar(32),   salary float ) ENGINE=ndbcluster; Since the primary key is a number, you can provide the key as a number to the find function. function onSession = function(err, session) {   if (err) {     console.log(err);     ... error handling   }   session.find('employee', 0, onData); }; function onData = function(err, data) {   if (err) {     console.log(err);     ... error handling   }   console.log('Found: ', JSON.stringify(data));   ... use data in application }; If you want to have the data stored in your own domain model, you tell the connector which table your domain model uses, by specifying an annotation, and pass your domain model to the find function. var annotations = new nosql.Annotations(); function Employee = function(id, name, salary) {   this.id = id;   this.name = name;   this.salary = salary;   this.giveRaise = function(percent) {     this.salary *= percent;   } }; annotations.mapClass(Employee, {'table' : 'employee'}); function onSession = function(err, session) {   if (err) {     console.log(err);     ... error handling   }   session.find(Employee, 0, onData); }; Updating data You can update the emp instance in memory, but to make the raise persistent, you need to write it back to the database, using the update function. function onData = function(err, emp) {   if (err) {     console.log(err);     ... error handling   }   console.log('Found: ', JSON.stringify(emp));   emp.giveRaise(0.12); // gee, thanks!   session.update(emp); // oops, session is out of scope here }; Using JavaScript can be tricky because it does not have the concept of block scope for variables. You can create a closure to handle these variables, or use a feature of the connector to remember your variables. The connector api takes a fixed number of parameters and returns a fixed number of result parameters to the callback function. But the connector will keep track of variables for you and return them to the callback. So in the above example, change the onSession function to remember the session variable, and you can refer to it in the onData function: function onSession = function(err, session) {   if (err) {     console.log(err);     ... error handling   }   session.find(Employee, 0, onData, session); }; function onData = function(err, emp, session) {   if (err) {     console.log(err);     ... error handling   }   console.log('Found: ', JSON.stringify(emp));   emp.giveRaise(0.12); // gee, thanks!   session.update(emp, onUpdate); // session is now in scope }; function onUpdate = function(err, emp) {   if (err) {     console.log(err);     ... error handling   } Inserting data Inserting data requires a mapped JavaScript user function (constructor) and a session. Create a variable and persist it: function onSession = function(err, session) {   var data = new Employee(999, 'Mat Keep', 20000000);   session.persist(data, onInsert);   } }; Deleting data To remove data from the database, use the session remove function. You use an instance of the domain object to identify the row you want to remove. Only the key field is relevant. function onSession = function(err, session) {   var key = new Employee(999);   session.remove(Employee, onDelete);   } }; More extensive queries We are working on the implementation of more extensive queries along the lines of the criteria query api. Stay tuned. How to evaluate The MySQL Connector for JavaScript is available for download from labs.mysql.com. Select the build: MySQL-Cluster-NoSQL-Connector-for-Node-js You can also clone the project on GitHub Since it is still early in development, feedback is especially valuable (so don't hesitate to leave comments on this blog, or head to the MySQL Cluster forum). Try it out and see how easy (and fast) it is to integrate MySQL Cluster into your Node.js platforms. You can learn more about other previewed functionality of MySQL Cluster 7.3 here

  • Want to book hotel stay using Bitcoin? Book using Expedia.com

    - by Gopinath
    The online travel booking leader Expedia announced that it started accepting Bitcoins for booking hotels on its website. For those who are new to Bitcoin, it is a digital currency in which transactions can be performed without the need for a central bank – its more like internet of currency. At the moment Expedia is accepting Bitcoin payments only for hotel bookings and in the future it may allow flights and vacation packages bookings. When Expedia customers wants to pay for a hotel using Bitcoin then they are transferred to Coinbase, a third party bit coin processor, for accepting the payments and then they are redirected back to Expedia.com to complete booking. This simple process would definitely drive mainstream adoption of Bitcoin – a win-win situation for digital currency users as well as for the travel company as they save a lot on card processing fees. Online retailers pay around 3% of transaction amount as fees for credit card processing companies like Visa & Master when they accept cards, but Coinbase charges a fee of just 1 percent for processing Bitcoins. Irrespective of customers adoption to Bitcoin based payments on Expedia as well as the savings on transaction fees, this move would give bragging rights to Expedia being the first e-commerce giant to accept digital currency!

  • SQLAuthority News – Whitepaper Download – Using Star Join and Few-Outer-Row Optimizations to Improve Data Warehousing Queries

    - by pinaldave
    Size of the database is growing every day. Many organizations now a days have more than TB of the Data in their system. Performance is always part of the issue. Microsoft is really paying attention to the same and also focusing on improving performance for Data Warehousing. Microsoft has recently released whitepaper on the performance tuning subject of Data Warehousing. Here is the abstract about the whitepaper from official site: In this white paper we discuss two of the new features introduced in SQL Server 2008, Star Join and Few-Outer-Row optimizations. These two features are in SQL Server 2008 R2 as well.  We test the performance of SQL Server 2008 on a set of complex data warehouse queries designed to highlight the effect of these two features and observed a significant performance gain over SQL Server 2005 (without these two features). The results observed also apply to SQL Server 2008 R2.  On average, about 75 percent of the query execution time has been reduced, compared to SQL Server 2005. We also include data that shows a reduction in the number of rows processed and improved balance in parallel queries, both of which highlight the important role the Star Join and Few Outer-Row features played. I encouraged all of those interested in Data Warehouse to read it and see if they can learn the tricks.

  • What does the "Maximum Frequency" number mean in the Windows Resource Monitor?

    - by nhinkle
    In the Windows Resource Monitor's CPU tab, there is a status box and graph for the "Maximum Frequency", right next to the "CPU Usage" values. What does this mean? The value is sometimes over 100% on my system... what could that imply? By looking at CPU-z's real-time report of the processor's clock speed, it seems to be loosely related to what frequency the CPU is running at, which would imply that it means "percent of maximum possible frequency the CPU is running at"; this would be of relevance on systems with SpeedStep and/or TurboBoost technology (or similar). Furthermore, setting the system to "power saving mode" lowers the "maximum frequency" value to around 60%, while setting it to "high performance" mode sets it to around 110%. However, the percentage does not seem to exactly correlate to the CPU speed being shown. What value is this actually representing then?

  • Can I get "disk utilization" from a NetApp filer via SNMP?

    - by Andrew
    On a NetApp filer's command line I'm running "sysstat -u" to show disk utilization, (actually the utilization of the single busiest disk). By disk utilization, I mean "percent of time the disk is busy", not "how much space on the disk is being used to store data/metadata". Is there a way to get disk utilization info through SNMP? The netapp.mib file doesn't appear to expose this. It does have CPU utilization, disk usage & capacity information, etc, but not disk utilization. The MIB-II (rfc1213) seems to be the only other information exposed by the filer through SNMP. I hope I am missing something. The "CP (consistency point) time" metric is exposed through the NETAPP-MIB in SNMP, but this seems to only partially correlate with disk utilization under write load, and not really at all under read load.
