  • Do we really need a thousand Linux distributions?

    - by nebukadnezzar
    Pointed from an answer to a (possibly related) question, I came across this graphic, and I'm shocked how many linux distributions currently exist. However, it seems that most of these distributions are forks of already popular distributions with minimal changes, usually limited to themes, wallpapers, buttons, the kind of stuff most people probably wouldn't see as a reason to fork a Linux distribution. Of course, someone will always say "Opensource is also about the freedom of choice", and while I wholeheartedly agree, I do not believe that this is a valid reason to fork an already perfectly working Distribution into a new one, which might possibly result in less security/stability due to smaller group of developers. There's another problem: Those, who want to switch to Linux, are confronted with a neverending list of Linux distributions, and wonder rightfully which they're supposed to chose (infact, I was facing that problem before I've discovered Ubuntu). There might be (very few) valid reasons to fork a distribution: Specializing on a particular topic (FOSS Only, work-related topic (i.e., for a Hospital), etc) An exceptional architecture, that requires a special set of software Use of non-FOSS, propietary technology, and such But even with these points in mind, it would still seem easier to create a subdistribution with the required changes, such as XUbuntu with XFCE4, KUbuntu with KDE4, Fluxbuntu with Fluxbox, etc. So, why exactly do we need so many distributions?

  • Is NAN suitable for communicating that an invalid parameter was involved in a calculation?

    - by Arman
    I am currently working on a numerical processing system that will be deployed in a performance-critical environment. It takes inputs in the form of numerical arrays (these use the eigen library, but for the purpose of this question that's perhaps immaterial), and performs some range of numerical computations (matrix products, concatenations, etc.) to produce outputs. All arrays are allocated statically and their sizes are known at compile time. However, some of the inputs may be invalid. In these exceptional cases, we still want the code to be computed and we still want outputs not "polluted" by invalid values to be used. To give an example, let's take the following trivial example (this is pseudo-code): Matrix a = {1, 2, NAN, 4}; // this is the "input" matrix Scalar b = 2; Matrix output = b * a; // this results in {2, 4, NAN, 8} The idea here is that 2, 4 and 8 are usable values, but the NAN should signal to the receipient of the data that that entry was involved in an operation that involved an invalid value, and should be discarded (this will be detected via a std::isfinite(value) check before the value is used). Is this a sound way of communicating and propagating unusable values, given that performance is critical and heap allocation is not an option (and neither are other resource-consuming constructs such as boost::optional or pointers)? Are there better ways of doing this? At this point I'm quite happy with the current setup but I was hoping to get some fresh ideas or productive criticism of the current implementation.

  • Jagran Prakashan Increases Staff Productivity by 40%

    - by Michael Snow
    Jagran Prakashan Increases Staff Productivity by 40%, Launches New IT Projects up to 4x Faster, Enables Mobile Service, and Improves Business Agility Oracle Customer: JPL Location:  Uttar Pradesh, India Industry: Media and Entertainment Employees:  10,000 Annual Revenue:  $100 to $500 Million Jagran Prakashan Ltd. (JPL) is one of India's premier media and communications groups with interests spanning print, advertising, event management, and mobile services for weather, cricket scores, and educational activities. It is a major media enterprise, with 300 locations across 15 states. Its impressive stable of print publications includes Dainik Jagran, the world’s most widely read daily newspaper––with a readership of over 55 million––the country’s leading afternoon dailies, and a range of popular local, bilingual, and English language newspapers. JPL was using multiple systems to manage its business processes. Users were resistant to using multiple passwords for various applications, preferring to continue their less efficient, legacy work practices. In addition, there was no single repository for sharing documents across the organization, such as company announcements or project documents. The company relied on e-mail to disseminate up-to-date company information, often missing employees. It was also time-consuming and difficult for managers to track the status of ongoing assignments or projects because collaboration and document sharing was inefficient and ineffective.With diverse businesses and many geographic locations, JPL needed to implement a centralized and user-friendly enterprise portal to improve document sharing and collaboration and increase business agility. The company implemented Oracle WebCenter Portal to create a dynamic, secure, and intuitive self-service enterprise portal to improve the user experience and increase operating efficiency. It improved staff productivity by 40%, accelerated new IT projects by up to 4x, boosted staff morale, and increased business agility.   Increases Staff Productivity by 40%, Launches New Products up to 2x Faster A word from JPL "With Oracle WebCenter Portal, we gained a dynamic, secure, and intuitive self-service enterprise portal that provided an exceptional user experience and enabled us to engage employees in a collaborative environment. It increased IT staff productivity by 40%, delivered new projects up to 4x faster, and enabled mobile service to improve our business agility.” Sarbani Bhatia, Vice President IT, Jagran Prakashahn Ltd Before implementing Oracle WebCenter Portal, JPL stored project-critical information, such as page planning of daily newspaper editions and the launch of new editions or supplements on individual laptops or in the e-mail system. Collaboration between colleagues was limited to physical meetings, telephone discussions, and e-mail. It was difficult to trace and recover important project documents when a staff member resigned, which represented a significant risk to business continuity. Employees were also averse to multiple passwords and resisted using the systems, affecting staff productivity. With Oracle WebCenter Portal, JPL created a dynamic, secure, and intuitive self-service enterprise portal with business activity streams. The portal allowed users to navigate, discover, and access information, such as advertising rates, requisition approvals, ad-hoc queries, and employee surveys from a single entry point with a single password. Managers can also upload important documents, such as new pricing for advertisers or newspaper distributors, and share them through the information and instruction section in the portal. In addition, managers can now easily track and review timelines for projects online rather than gathering information from meetings and e-mails. The company gained the ability to centrally manage information, ensured business continuity, and improved staff productivity by 40%.“In the media industry, news has a very short shelf life, so speed is crucial. Information delayed is like information lost,” said Sarbani Bhatia, vice president IT, Jagran Prakashahn Ltd. “Thanks to Oracle WebCenter Portal’s contextual collaboration tools, we can provide and share feedback for new project launches, such as career or education supplements, up to 2x faster through discussion forums or knowledge groups. Tasks that previously required four months, we now complete in one month.”In addition, the company can broadcast announcements, flash employee birthdays, and promote important events through the message section on the webpage, instead of using the e-mail system. The company can also conduct opinion polls to gauge employee response to organizational issues and improve management decision-making.“With over 10,000 employees across 300 locations, it is critical for management to hear the voice of employees and develop a cohesive organizational culture. Oracle WebCenter Portal enables employees to engage with business processes and systems in a collaborative environment, providing users with an exceptional experience,” Bhatia said. Enables Mobility Access and Increases Business Agility Newspaper advertisements generate the majority of JPL’s revenue. With most sales staff on the move, the company needed to ensure timely approval of print advertisement discounts for specific clients and meet tight publication deadlines.  By integrating Oracle WebCenter Portal seamlessly with its enterprise resource planning (ERP) system and other applications, such as the organizational mass mailing system, business intelligence, and management information system, JPL embedded its approval workflow processes into the enterprise portal and provided users with an integrated and intuitive interface. About 30% of JPL’s sales staff members now have tablets and receive advertising discount approval from managers while in the field and no longer need to return to the office, which has significantly improved efficiency and increased business agility.“Application mobility was critical for sales representatives in the field to meet stringent auditing requirements for online accountability, particularly for our newspaper advertising business. Staff member satisfaction has improved significantly now that the sales team can use tablets to access the portal––a capability we will extend to smart phones in the second stage of the implementation,” Bhatia said. Accelerates Application Development by up to 4x and Cuts Costs by up to 60% With Oracle WebCenter Portal, users can easily create, modify, and upload information to their personalized webpages without IT assistance. By seamlessly integrating Oracle WebCenter Portal with the payroll database, managers can decide which members of their team can access the page and with whom they will share information, a decision based on role or geographical location. A sales representative selling advertising space for a local language daily newspaper, for example, can upload an updated advertising rate relevant only to that particular publication. Users can also easily adapt to the new platform, thanks to its intuitive design and look, reducing the need for training and lowering resistance to using the system.Using Oracle WebCenter Portal’s out-of-the-box reusable components, such as portal pages and templates, provided JPL’s developers with a comprehensive and flexible user experience platform and increased the speed of application development. In less than five months, JPL developed more than 55 workflows. The IT team accelerated deployment of new applications by up to 4x, as they do not need to install them on individual machines now that they have a web-based environment.   “Previously, we would have spent a whole day deploying a new application for each department or location. With a browser-based environment, we have cut costs by up to 60% by reducing deployment time to zero, because our IT team can roll out a new application from a single point, thanks to Oracle WebCenter Portal,” Bhatia said. Challenges Provide a dynamic, secure, and intuitive self-service enterprise portal to improve staff productivity and ensure business continuity Enable seamless integration with multiple enterprise applications to improve workflow efficiency—including approval of print advertisement discounts—and increase business agility Improve engagement with employees and enable collaboration to enhance management decision-making Accelerate time-to-market for new services, such as new advertising programs Solutions Oracle Product and ServicesOracle WebCenter Portal 11g Increased staff productivity by 40% and enhanced user satisfaction by enabling employees to easily navigate, discover, and access information from a single, self-service enterprise portal without IT assistance Launched new products, such as career or education supplements, up to 2x faster by enabling peer collaboration and incorporating feedback generated through discussion forums, thanks to Oracle WebCenter Portal’s out-of-the-box collaboration tools Accelerated application development up to 4x by enabling developers to optimize reusable components for managing and deploying new applications in a browser-based environment rather than spending one day to install applications for each department, cutting costs by up to 60% Ensured business continuity by enabling managers to easily track and review project timelines online rather than storing important documents on individual laptops or relying on the e-mail system Increased business agility and operational efficiency by seamlessly integrating with the in-house, ERP system and embedding business processes into a single portal Boosted company revenue by enabling sales team members to submit print-advertising discount requests through mobile devices instead of waiting to return to office, ensuring timely approval from managers to meet tight publication deadlines Improved management decision-making by enabling employees to easily share and access feedback through opinion polls or forums, boosting staff morale Introduced the single sign-on capability and enhanced security by enabling managers to decide access level for staff members based on role or geographical location Reduced the need for staff training and minimized user resistance to systems by providing a dynamic and intuitive user experience Why Oracle JPL did not consider other products because the company was already using Oracle Database, Enterprise Edition with Real Application Clusters and had a positive experience with Oracle. JPL chose Oracle WebCenter Portal to ensure no compatibility issues for integration with its existing Oracle products and to take advantage of the experience and support of a reputable vendor to ensure business continuity. “We chose Oracle because we knew we could rely on its support and experience. In addition, Oracle WebCenter Portal’s speed, agility, and mobile access features were a perfect fit for our business requirements,” Bhatia said. Implementation Process JPL launched the enterprise portal to 500 users in the first phase of the project, and plans to extend this to 2,000 users when the portal is fully launched. Oracle partner PricewaterhouseCoopers used Oracle Application Development Framework for the intial set-up, user training and to develop and design sample workflows. JPL’s internal IT staff then took charge of the implementation, bringing it to completion on budget. Partner Oracle PartnerPricewaterhouseCoopers (India)

  • 2D platformers: why make the physics dependent on the framerate?

    - by Archagon
    "Super Meat Boy" is a difficult platformer that recently came out for PC, requiring exceptional control and pixel-perfect jumping. The physics code in the game is dependent on the framerate, which is locked to 60fps; this means that if your computer can't run the game at full speed, the physics will go insane, causing (among other things) your character to run slower and fall through the ground. Furthermore, if vsync is off, the game runs extremely fast. Could those experienced with 2D game programming help explain why the game was coded this way? Wouldn't a physics loop running at a constant rate be a better solution? (Actually, I think a physics loop is used for parts of the game, since some of the entities continue to move normally regardless of the framerate. Your character, on the other hand, runs exactly [fps/60] as fast.) What bothers me about this implementation is the loss of abstraction between the game engine and the graphics rendering, which depends on system-specific things like the monitor, graphics card, and CPU. If, for whatever reason, your computer can't handle vsync, or can't run the game at exactly 60fps, it'll break spectacularly. Why should the rendering step in any way influence the physics calculations? (Most games nowadays would either slow down the game or skip frames.) On the other hand, I understand that old-school platformers on the NES and SNES depended on a fixed framerate for much of their control and physics. Why is this, and would it be possible to create a patformer in that vein without having the framerate dependency? Is there necessarily a loss of precision if you separate the graphics rendering from the rest of the engine? Thank you, and sorry if the question was confusing.

  • The next next C++ [closed]

    - by Roger Pate
    It's entirely too early for speculation on what C++ will be like after C++0x, but idle hands make for wild predictions. What features would you find useful and why? Is there anything in another language that would fit nicely into the state of C++ after 0x? What should be considered for the next TC and TR? (Mostly TR, as the TC would depend more on what actually becomes the next standard.) Export was removed, rather than merely deprecated, in 0x. (It remains a keyword.) What other features carry so much baggage to also be more harmful than helpful? ISO Standards' process I'm not involved in the C++ committee, but it's also a mystery, unfortunately, to most programmers using C++. A few things worth keeping in mind: There will be 10 years between standards, barring extremely exceptional circumstances. The standard can get "bug fixes" in the form of a Technical Corrigendum. This happened to C++98 with TC1, named C++03. It fixed "simple" issues such as making the explicit guarantee that std::vector stores items contiguously, which was always intended. The committee can issue reports which can add to the language. This happened to C++98/03 with TR1 in 2005, which introduced the std::tr1 namespace.

  • Top 25 security issues for developers of web sites

    - by BizTalk Visionary
    Sourced from: CWE This is a brief listing of the Top 25 items, using the general ranking. NOTE: 16 other weaknesses were considered for inclusion in the Top 25, but their general scores were not high enough. They are listed in the On the Cusp focus profile.

Even when a software package doesn't primarily run on the web, there's a good chance that it has a web-based management interface or HTML-based output formats that allow cross-site scripting. For data-rich software applications, SQL injection is the means to steal the keys to the kingdom. The classic buffer overflow comes in third, while more complex buffer overflow variants are sprinkled in the rest of the Top 25.

  • New Oracle Solaris 11 Administration book

    - by glynn
    During the development of Oracle Solaris 11, one of the main goals was to modernize the operating system and remove some of the existing frustrations that our administrative audience had in deploying and using the platform within data centers around the world. That meant a comprehensive clean out of some existing technologies to provision the operating system (replacing Jumpstart with Automated Installer) and manage system software (replacing SVR4 with IPS packaging), consolidate the vast spectrum of networking configuration, and enhance the user environment to provide familiarity for those who were used to administering Linux environments among many other things. While some considered the changes to Oracle Solaris 11 as a negative change, most will be impressed at how far we've come - the deeper integration of key technologies, presented in a consolidated and consistent form. It is easier to administer the Oracle Solaris platform that ever before, and I have no doubt that administrators coming from other platforms will be hugely impressed with what they see, especially if they're judging based on past experiences of Solaris 8 and Solaris 9. In fact I'd go further to say that Oracle Solaris 11 is a more powerful, integrated and usable platform that most Linux platforms I've seen. But as with anything, there's always an initial learning curve to get through. We've provided a significant selection of learning materials out on the Oracle Solaris 11 pages on Oracle Technology Network and some great training and certification options. One more option is now available in the form of a book, the Oracle Solaris 11 System Administration The Complete Reference. This provides an exceptional reference to help administrators learn about Oracle Solaris 11, especially those who have come from the Linux platform. As is quoted in the first chapter of the guide: Linux users and developers will find in Oracle Solaris 11 a familiar and quickly productive working environment; we point out similarities and differences between the Linux and Solaris kernels and system administration tools, and describe how typical open source Web development tasks are accomplished in this OS. So I would encourage you to take a read of it and start seriously considering Oracle Solaris 11 to be a platform choice for your data center. Oracle Solaris 11 System Administration The Complete Reference - yours for only $32.50 (if you successfully use the promotion code - otherwise worth shopping around to pick up a good deal).

  • Is there such a thing as a super programmer? [closed]

    - by Muhammad Alkarouri
    Have you come across a super programmer? What identifies him or her as such, compared to "normal" experienced/great programmers? Also. how do you deal with a person in your team who believes he is a super programmer? Both in case he actually is or if he isn't? Edit: Interesting inputs all round, thanks. A few things can be gleaned: A few definitions emerged. Disregarding too localised definitions (that identified the authors or their acquaintance as super programmers), I liked a couple definitions: Thorbjørn's definition: a person who does the equivalent of a good team consistently for a long time. Free Electron, linked from Henry's answer. A very productive person, of exceptional abilities. The explanation is a good read. A Free Electron can do anything when it comes to code. They can write a complete application from scratch, learn a language in a weekend, and, most importantly, they can dive into a tremendous pile of spaghetti code, make sense of it, and actually getting it working. You can build an entire businesses around a Free Electron. They’re that good. Contrasting with the last definition, is the point linked to by James about the myth of the genius programmer (video). The same idea is expressed as egoless programming in rwong's comment. They present opposite opinions as whether to optimise for such a unique programmer or for a team. These definitions are definitely different, so I would appreciate it if you have an input as to which is better. Or add your own if you want of course, though it would help to say why it is different from those.

  • How to Deliberately Practice Software Engineering?

    - by JasCav
    I just finished reading this recent article. It's a very interesting read, and it makes some great points. The point that specifically jumped out at me was this: The difference was in how they spent this [equal] time. The elite players were spending almost three times more hours than the average players on deliberate practice — the uncomfortable, methodical work of stretching your ability. This article (if you care not to read it) is discussing violin players. Of course, being a software engineer, my mind turned towards software ability. Granted, there are some very naturally talented individuals out there, but time and time again, it is those folks who stretch their abilities through deliberate practice that really become exceptional at their craft. My question is - how would one go about practicing the "scales" of software engineering and computer science? When I practice the piano, I will spend more of my time on scales and less on a fun song. How can I do the same in developing software? To head off early answers, I don't feel that "work on an open source project," and similar answers, is really right. Sure...that can improve your skills, but you could just as easily get stuck focusing on something that is unimportant to your craft as a whole. It can become the equivalent of learning "Twinkle Twinkle Little Star" and never being able to play Chopin. So, again, I ask - how would you suggest that someone deliberately practice software engineering?

  • SSISDB Analysis Script on Gist

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

  • How to avoid throwing vexing exceptions?

    - by Mike
    Reading Eric Lippert's article on exceptions was definitely an eye opener on how I should approach exceptions, both as the producer and as the consumer. However, I'm still struggling to define a guideline regarding how to avoid throwing vexing exceptions. Specifically: Suppose you have a Save method that can fail because a) Somebody else modified the record before you, or b) The value you're trying to create already exists. These conditions are to be expected and not exceptional, so instead of throwing an exception you decide to create a Try version of your method, TrySave, which returns a boolean indicating if the save succeeded. But if it fails, how will the consumer know what was the problem? Or would it be best to return an enum indicating the result, kind of Ok/RecordAlreadyModified/ValueAlreadyExists? With integer.TryParse this problem doesn't exist, since there's only one reason the method can fail. Is the previous example really a vexing situation? Or would throwing an exception in this case be the preferred way? I know that's how it's done in most libraries and frameworks, including the Entity framework. How do you decide when to create a Try version of your method vs. providing some way to test beforehand if the method will work or not? I'm currently following these guidelines: If there is the chance of a race condition, then create a Try version. This prevents the need for the consumer to catch an exogenous exception. For example, in the Save method described before. If the method to test the condition pretty much would do all that the original method does, then create a Try version. For example, integer.TryParse(). In any other case, create a method to test the condition.

  • Leading Analyst Firm Positions Oracle in Leaders Quadrant for Web Content Management

    - by Christie Flanagan
    Gartner, Inc. has named Oracle a Leader in its latest “Magic Quadrant for Web Content Management.” Gartner’s Magic Quadrants position vendors within a particular quadrant based on their completeness of vision and their ability to execute on that vision. According to Gartner, “WCM plays an increasingly important role in business performance. It has become the central point of coordination for initiatives involving the enterprise's online presence, and these initiatives have become more sophisticated and more important to enterprises' business strategies. Thus, WCM is key for organizations wishing to execute a strategy of OCO (online channel optimization) that embraces areas such as customer experience management, e-commerce, digital marketing, multichannel marketing and website consolidation.” Gartner continued, “Leaders should drive market transformation. Leaders have the highest combined scores for Ability to Execute and Completeness of Vision. They are doing well and are prepared for the future with a clear vision and a thorough appreciation of the broader context of OCO. They have strong channel partners, a presence in multiple regions, consistent financial performance, broad platform support and good customer support. In addition, they dominate in one or more technologies or vertical markets. Leaders are aware of the ecosystem in which their offerings need to fit. Leaders can: demonstrate enterprise deployments’ offer integration with other business applications and content repositories; provide a vertical-process or horizontal-solution focus.” Oracle WebCenter, the engagement platform powering exceptional experiences for customers, employees and partners, connects people and information by bringing together the most complete portfolio of portal, Web experience management, content, social, and collaboration technologies into a single integrated product suite. Oracle WebCenter also provides the foundation for Oracle Fusion Middleware and Oracle Fusion Applications to deliver a next-generation user experience.  To see the latest reports, webcasts and demonstrations about Oracle's web experience management solution, Oracle WebCenter Sites, please visit our Connected Customer Experience Resource Center.

  • Query something and return the reason if nothing has been found

    - by Daniel Hilgarth
    Assume I have a Query - as in CQS that is supposed to return a single value. Let's assume that the case that no value is found is not exceptional, so no exception will be thrown in this case. Instead, null is returned. However, if no value has been found, I need to act according to the reason why no value has been found. Assuming that the Query knows the reason, how would I communicate it to the caller of the Query? A simple solution would be not return the value directly but a container object that contains the value and the reason: public class QueryResult { public TValue Value { get; private set; } public TReason ReasonForNoValue { get; private set; } } But that feels clumsy, because if a value is found, ReasonForNoValue makes no sense and if no value has been found, Value makes no sense. What other options do I have to communicate the reason? What do you think of one event per reason? For reference: This is going to be implemented in C#.

  • You may be tempted by IaaS, but you should PaaS on that or your database cloud journey will be a short one

    - by B R Clouse
    Before we examine Consolidation, the next step in the journey to cloud, let's take a short detour to address a critical choice you will face at the outset of your journey: whether to deploy your databases in virtual machines or not. A common misconception we've encountered is the belief that moving to cloud computing can be accomplished by simply hosting one's current operating environment as-is within virtual machines, and then stacking those VMs together in a consolidated environment.  This solution is often described as "Infrastructure as a Service" (IaaS) because the building block for deployments is a VM, which behaves like a full complement of infrastructure.  This approach is easy to understand and may feel like a good first step, but it won't take your databases very far in the journey to cloud computing.  In fact, if you follow the IaaS fork in the road, your journey will end quickly, without realizing the full benefits of cloud computing.  The better option to is to rationalize the deployment stack so that VMs are needed only for exceptional cases.  By settling on a standard operating system and patch level, you create an infrastructure that potentially all of your databases can share.  Now, the building block will be database instances or possibly schemas within databases.  These components are the platforms on which you will deploy workloads, hence this is known as "Platform as a Service" (PaaS). PaaS opens the door to higher degrees of consolidation than IaaS, because with PaaS you will not need to accommodate the footprint (operating system, hypervisor, processes, ...) that each VM brings with it.  You will also reduce your maintenance overheard if you move forward without the VMs and their O/Ses to patch and monitor.  So while IaaS simply shuffles complex and varied environments into VMs,  PaaS actually reduces complexity by rationalizing to the small possible set of components.  Now we're ready to look at the consolidation options that PaaS provides -- in our next blog posting.

  • How to write regex in asp.net MVC 3 razor

    - by anirudha
    here is a small trick to write regex and exceptional code in MVC3. first trick is use @@ instead of @ it’s work don’ worry output goes @ not @@. second trick is that you can use <text></text> tag in MVC to use some code who give error because viewengine does not accept them. like var pattern = new RegExp(/^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i);   this regex not work because it’s use @ so replace them to @@ e var pattern = new RegExp(/^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(@@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i); now it will work. second way is that use text tag in MVC to make them work like <text> function isValidEmailAddress(emailAddress) { var pattern = new RegExp(/^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i); return pattern.test(emailAddress); } </text>

  • Why have we got so many Linux distributions? [closed]

    - by nebukadnezzar
    Pointed to from an answer to another question, I came across this graphic, and I'm shocked how many linux distributions currently exist. However, it seems that most of these distributions are forks of already popular distributions with minimal changes, usually limited to themes, wallpapers and buttons. It would still seem easier to create a sub-distribution with the required changes, such as XUbuntu with XFCE4, KUbuntu with KDE4, Fluxbuntu with Fluxbox, etc. In my mind there are a number of problems with having so many distributions - perhaps less security/stability due to smaller group of developers, and also the confusingly vast range of choice for newcomers to Linux. Some reasons that developers might decide to fork are: Specializing on a particular topic (work-related topic - i.e. for a Hospital, etc) An exceptional architecture, that requires a special set of software Use of non-FOSS, proprietary technology, and such So what other reasons are there that have caused so many people decided to create their own distributions? What are the thought processes that have led to this? And are these "valid" reasons - do we need so many distributions? If you can back your experiences up with references that would be great.
