  • Windows Phone 7 : la mise à jour de mars pourrait être retardée, et n'arriver que le lundi 21

    Windows Phone 7 : la mise à jour de mars pourrait être retardée, et n'arriver que le lundi 21 Mise à jour du 10.03.2011 par Katleen La mise à jour de Windows Phone 7 prévue pour début mars, comme l'avait annoncé Steve Ballmer en février, pourrait être légèrement repoussée. En effet, elle "sera disponible pour la deuxième quinzaine de Mars". Cette arrivée pendant la seconde moitié du mois, voir même sa fin, est un retard comparé à ce qui était attendu. Un site américain avance même une date de sortie au 21 mars, ce qui éloigne des prédictions faites par le CEO de Microsoft. Quoiqu'il en soit, la firme ne compte pas s'arrêter là et proposera de nouvelles updates ...

  • PaaS, DBaaS and the Oracle Database Cloud Service

This variation is evident in one of the key misunderstandings about the Oracle Database Cloud Service. People could be forgiven for thinking that the Database Cloud Service was a Database-as-a-Service (DBaaS), but this is actually not true. The Database Cloud Service is a Platform-as-a-Service, which presents a different user and developer interface and has a different set of qualities. A good way to think about the difference between these two varieties of Cloud offerings is that you, the customer, have to deal with things at the level of the offering, but not for anything below it. In practice, this means that you do not have to deal with hardware or system software, including installation and maintenance, for DBaaS. You also do not have much control over configuration of these options. For PaaS, you don’t have to deal with hardware, system software, or database software – and also do not have control over these levels in the stack. So you cannot modify configuration parameters for the database with the Database Cloud Service – your interface is through SQL and PL/SQL, with Application Express, included in the Database Cloud Service, or through JDBC for Java apps running in the Java Cloud Service, or through RESTful Web Services. You will notice what is not mentioned there – SQL*Net. You cannot access your Oracle Database Cloud Service by changing an entry in the TNSNames file and using SQL*Net. So the effort involved in migrating an existing Oracle Database in your data center to the Database Cloud Service may be prohibitive. The good news is that Application Express and the RESTful Web Services wizard in the Database Cloud Service allow you to develop new applications very quickly, and, of course, the provisioning of the entire Database Cloud Service takes only minutes.

  • Why Is Another Domain Resolving To My IP Address?

    - by Andrew
    I'm not really sure if this is something that I should worry about... I'm currently renting a dedicated server which is hosting a website I've created. The domain of the website was registered with GoDaddy. After submitting a sitemap to Google several months ago, I've noticed that another domain name is resolving to my IP address. This means that every page on my website is actually accessible from another domain. As far as I can tell, the other domain name is meaningless to me, so I'm not sure if this is something I should worry about or not. Is this a residual DNS record from another site that is probably no longer in use? Is it important from the standpoint of either security or SEO? My website is a .com which will later serve e-commerce purposes. The other domain has a top-level domain of st. It's the first one of those that I've encountered. Many thanks in advance!

  • Cannot execute binary file

    - by user291727
    I am new to Ubuntu and I'm trying to install Popcorn Time. I downloaded 32 bit version and tried to install it but that's where the problem started showing. I duble clicked the executable file and well, nothing happened. It's a official download from their web-site but it doesn't work. Maybe I'm doing something wrong.....Anyway, I found out that you can insatll it from a script, but people keep talking in ubuntu terms and I don't understand it, so I have a few questions: 1.How to make a script? (witch I'm suppose to run in terminal using bash comand), 2.Is it normal that i cannot run the installer, and if that is an installer or just files for the program. 3.If it is an installer, how do I make it work? 4.What does " Cannot execute binary file" mean? Thank you in advance, hope I'm not asking too many questions(please understand that I'm new to ubuntu) and sorry about my English. xD

  • What is the name for landing pages that are one long page?

    - by blunders
    Really don't see them much anymore, but here's an example of what I mean: From comments: These are "high pressure" sales pages, design to overload the user with information, sell them on the belief that what they're buying is what they need, normally have a lot of testimonials, highlighted text, etc. The pages I'm talking about are not user friendly, they're aggressive sales pitches designed to target users wanting to belief the webpage they just landed on will solve there problems for an "affordable" price. Here's an example: www_landingpagecashmachine_com (remove the underscores, since I'm attempting to avoid linking to a site like that...) Bonus points: if you're able to tell me the name of the guy/company that popularized these types of pages; recall hearing about his company years ago, after he died in a crash while racing on a track with his Ferrari club on the west coast of the US. (Update: Appears Corey Rudl was the guy's name, and his company was called "The Internet Marketing Center." Even with that info, I've still been unable to find the name for these type of pages.)

  • Openmatics Revolutionizes Fleet Management with Standards-Based Vehicle Telematics Platform

    - by Michael Snow
    Openmatics s.r.o. was founded in 2010 as a subsidiary of ZF Friedrichshafen AG, a global player in driveline and chassis technology. Oracle Customer:  Openmatics s.r.o.Location:  Pilsen, Czech RepublicIndustry:  AutomotiveEmployees:  70 Its goal was to develop and operate a flexible, open telematics platform for automotive applications, which is independent from vehicle and component suppliers—recognizing that the fragmented telematics market was not meeting today’s fleet management needs. Openmatics provides a rich product portfolio, and customers can extend the platform, as required, to meet their needs. Partners and third-parties can develop their own applications using the Openmatics’ software development kit and can sell them via the Openmatics app shop.ZF Friedrichshafen AG is a global player in driveline and chassis technology. With 121 production companies and 650 service partners in 26 countries, ZF is among the top 10 largest automotive suppliers worldwide. Founded in 1915 to develop and produce transmissions for airships and vehicles, the group’s product offerings now include transmissions and steering systems as well as chassis components and complete axle systems and modules.  A word from Openmatics s.r.o.  “Oracle WebCenter Portal, together with the underlying Oracle Application Development Framework, provided the fundamental infrastructure for the Openmatics platform. Fleet managers can now reduce fuel consumption and operating costs, and more efficiently manage vehicle usage, maintenance, and safety. The standards-based platform allows third-party suppliers to deploy their own vehicle telematics services as Openmatics apps and creates a de facto standard for the automotive industry, independent from a single manufacturer or service provider.” – Gero Strobel, Head of Development, Openmatics s.r.o. Challenges Create an industry standard for vehicle telematics by establishing a customizable platform that enables access to telematics information, such as current and past fuel consumption, through a web browser to better meet automotive market and customer needs Reduce fleet-management costs by eliminating the need to invest in isolated telematics hardware and software solutions per vehicle brand and vehicle component manufacturer Establish an open platform where third-party providers—such as original equipment manufacturers (OEM), insurers, fleet operators, and individual developers—can deploy their own vehicle telematics services Allow users to purchase targeted telematics services as single apps to reduce costs and ensure rapid growth of telematics services available on the platform Enable users to configure their telematics apps with ease to make sure the platform meets individual fleet management requirements, such as analyzing past and current fuel consumption of a truck fleet Solutions Deployed Oracle WebCenter Portal as a foundation for Openmatics, a standards-based automotive telematics platform that provides next-generation fleet management with unified digital communication from and to vehicles on the move Used Oracle Application Development Framework as the development framework for Oracle WebCenter Portal’s components and services, providing developers with ready-to-use software development kits with application programming interfaces, design templates, and visual tools that accelerated time to market Used Oracle Enterprise Pack for Eclipse to simplify telematics application development in Java Enabled fleet monitoring by recording vehicle data—such as fuel consumption information—through onboard units, delivering the information to Oracle Database, and making it accessible through a customizable app portfolio on any web browser Stored vehicle telematics data—sent as encrypted information—in Oracle Database, ensuring data integrity and immediate availability for the platform’s telematics applications Enabled a wide range of telematics services suppliers, from vehicle component manufacturers to fleet application developers, to offer vehicle telematics services on the Openmatics platform, ensuring platform independence from OEMs Provided Openmatics customers with the means to individually select the automotive telematics services that are relevant to their business requirements, eliminating the need to pay for superfluous information and reducing fleet management costs Oracle Products & Services Oracle Application Development Framework Oracle WebCenter Portal Oracle SOA Suite Oracle Enterprise Pack for Eclipse Oracle Database Oracle Consulting &amp;amp;amp;amp;amp;amp;amp;&amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;gt;amp;&amp;amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;amp;gt;lt;p&amp;amp;amp;amp;amp;amp;amp;amp;gt; &amp;amp;amp;amp;amp;amp;amp;amp;lt;/p&amp;amp;amp;amp;amp;amp;amp;amp;gt;

  • What measures can be taken to increase Google indexing speed for a given newly created page?

    - by knorv
    Consider a website with a large number of pages. New pages are published regularly. When publishing a new page the website operator wants to get the newly created paged indexed in Google as soon as possible. The website operator wants to minimize the time spent between publication and indexing. Consider the site http://www.example.com/ with hundreds of thousands of pages. The page page http://www.example.com/something/important-page.html is created at say 12:00. How do I get important-page.html indexed as soon as possible after 12:00? Ideally within seconds or minutes. Or more generally: What options are available to try to get Google to index a specific newly created page as soon as possible?

  • How to configure Google Analytics experiments manually

    - by John
    I wish to run multivariate tests on an e-commerce site that run across all product pages. I will be setting and deciding the variations myself all I need to do is track the results in GA. I think may be possible (although only A/B testing is available via the GA UI): https://developers.google.com/analytics/devguides/platform/features/experiments#serving-framework EXTERNAL – You will choose variations, handle experiment optimization, and only report the chosen variation to Google Analytics. For example, this should be used by 3rd-party optimization platforms that want to integrate with Google Analytics for reporting purposes. In this case, the Google Analytics statistical engine will not run. However how do I configure this and push the data to GA in my page?

  • Documenting a REST interface with a flowchart

    - by James Kassemi
    Does anybody have suggestions on creating a flowchart representation of a REST-style web interface? In the interest of supplying thorough documentation to co-developers, I've been toying around in dia modeling the interface for modifying and generating a product resource: This particular system begins to act differently with user authentication/resource counts, so before I make modifications, I'm looking for some clarification: Complexity: how would you simplify the overall structure to make this easier to read? Display Symbol: is this appropriate for representing a page? Manual Operation Symbol: is this appropriate for representing a user action like a button click? Any other suggestions would be greatly appreciated. My apologies for the re-post. The main stackexchange site suggested this question was better presented on programmers.

  • Jquery Carousel - Need A Script Hack to Customize

    I hope someone can help me out here. I am coding a site for a client using the carouFredsel. I am using this because it allows for variable widths with in the slideshow as seen here: http://2938.sandbox.i3dthemes.net/index-old.html. My problems are as follows: to use the built in auto center script the scrolling changes the white space in between images during the transition to fit the width of the wrapper. I need a hack to keep the white space during transition the same, like this: http://2938.sandbox.i3dthemes.net/index.html. Also, I can't figure out how to put this snippet into my code and make it work scroll: { onAfter: function() { if ( $(this).triggerHandler( "currentPosition" ) == 0 ) { $(this).trigger( "pause" ); } } }

  • ANTLRWorks 2: Early Access Preview 10

    - by Geertjan
    I took a quick look at how the ANTLRWorks 2 project is getting on... and discovered that today, March 23, the new early access preview 10 has been released: http://www.antlr.org/wiki/display/ANTLR4/1.+Overview Downloaded it immediately and was impressed when browsing through the Java.g file that I also found on the Antlr site: (Click to enlarge the image above.) On the page above, the following enhancements are listed: Add tooltips for rule references Finally fixed the navigator update bug Major improvements to code completion Fix legacy mode Many performance and stability updates I've blogged before about how the developers on the above project consider their code completion to be "scary fast". Some discussions have taken place about how code developed by the ANTLRWorks team could be contributed to the NetBeans project, since NetBeans IDE and ANTLRWorks 2 are both based on the NetBeans Platform.

  • URL Rewrite http to https EXCEPT files in a specific subfolder

    - by BrettRobi
    I am trying to force all traffic on my web site to use HTTPS, using the URL Rewrite 2.0 module added to IIS 7.5. I got that working and now have a need to exclude a couple of pages from using SSL. So I need a rule to rewrite all URL except those referencing this folder to HTTPS. I've been banging my head against the wall on this and am hoping someone can help. I tried creating a rule to match all URL except those in a nossl subfolder as in this example: <rule name="HTTP to HTTPS redirect" enabled="true" stopProcessing="true"> <match url="(/nossl/.*)" negate="true" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false"> <add input="{HTTPS}" pattern="off" /> </conditions> <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Found" /> </rule> But this doesn't work.

  • Columnstore Case Study #1: MSIT SONAR Aggregations

    - by aspiringgeek
    Preamble This is the first in a series of posts documenting big wins encountered using columnstore indexes in SQL Server 2012 & 2014.  Many of these can be found in this deck along with details such as internals, best practices, caveats, etc.  The purpose of sharing the case studies in this context is to provide an easy-to-consume quick-reference alternative. Why Columnstore? If we’re looking for a subset of columns from one or a few rows, given the right indexes, SQL Server can do a superlative job of providing an answer. If we’re asking a question which by design needs to hit lots of rows—DW, reporting, aggregations, grouping, scans, etc., SQL Server has never had a good mechanism—until columnstore. Columnstore indexes were introduced in SQL Server 2012. However, they're still largely unknown. Some adoption blockers existed; yet columnstore was nonetheless a game changer for many apps.  In SQL Server 2014, potential blockers have been largely removed & they're going to profoundly change the way we interact with our data.  The purpose of this series is to share the performance benefits of columnstore & documenting columnstore is a compelling reason to upgrade to SQL Server 2014. App: MSIT SONAR Aggregations At MSIT, performance & configuration data is captured by SCOM. We archive much of the data in a partitioned data warehouse table in SQL Server 2012 for reporting via an application called SONAR.  By definition, this is a primary use case for columnstore—report queries requiring aggregation over large numbers of rows.  New data is refreshed each night by an automated table partitioning mechanism—a best practices scenario for columnstore. The Win Compared to performance using classic indexing which resulted in the expected query plan selection including partition elimination vs. SQL Server 2012 nonclustered columnstore, query performance increased significantly.  Logical reads were reduced by over a factor of 50; both CPU & duration improved by factors of 20 or more.  Other than creating the columnstore index, no special modifications or tweaks to the app or databases schema were necessary to achieve the performance improvements.  Existing nonclustered indexes were rendered superfluous & were deleted, thus mitigating maintenance challenges such as defragging as well as conserving disk capacity. Details The table provides the raw data & summarizes the performance deltas. Logical Reads (8K pages) CPU (ms) Durn (ms) Columnstore 160,323 20,360 9,786 Conventional Table & Indexes 9,053,423 549,608 193,903 ? x56 x27 x20 The charts provide additional perspective of this data.  "Conventional vs. Columnstore Metrics" document the raw data.  Note on this linear display the magnitude of the conventional index performance vs. columnstore.  The “Metrics (?)” chart expresses these values as a ratio. Summary For DW, reports, & other BI workloads, columnstore often provides significant performance enhancements relative to conventional indexing.  I have documented here, the first in a series of reports on columnstore implementations, results from an initial implementation at MSIT in which logical reads were reduced by over a factor of 50; both CPU & duration improved by factors of 20 or more.  Subsequent features in this series document performance enhancements that are even more significant.
