  • Why is it a good practice to wrap all primitives and Strings?

    - by Amogh Talpallikar
    According to Jeff Bay's Essay on Object Callisthenics, One of the practices is set to be "Wrap all primitives and Strings" Can anyone elaborate on this ? In languages where we already have wrappers for primitives like C# and Java. and In languages where Collections can have generics where you are sure of what type goes into the collection, do we need to wrap string's inside their own classes ? Does it have any other advantage ?

  • A Community Cure for a String Splitting Headache

    - by Tony Davis
    A heartwarming tale of dogged perseverance and Community collaboration to solve some SQL Server string-related headaches. Michael J Swart posted a blog this week that had me smiling in recognition and agreement, describing how an inquisitive Developer or DBA deals with a problem. It's a three-step process, starting with discomfort and anxiety; a feeling that one doesn't know as much about one's chosen specialized subject as previously thought. It progresses through a phase of intense research and learning until finally one achieves breakthrough, blessed relief and renewed optimism. In this case, the discomfort was provoked by the mystery of massively high CPU when searching Unicode strings in SQL Server. Michael explored the problem via Stack Overflow, Google and Twitter #sqlhelp, finally leading to resolution and a blog post that shared what he learned. Perfect; except that sometimes you have to be prepared to share what you've learned so far, while still mired in the phase of nagging discomfort. A good recent example of this recently can be found on our own blogs. Despite being a loud advocate of the lightning fast T-SQL-based string splitting techniques, honed to near perfection over many years by Jeff Moden and others, Phil Factor retained a dogged conviction that, in theory, shredding element-based XML using XQuery ought to be even more efficient for splitting a string to create a table. After some careful testing, he found instead that the XML way performed and scaled miserably by comparison. Somewhat subdued, and with a nagging feeling that perhaps he was still missing "something", he posted his findings. What happened next was a joy to behold; the community jumped in to suggest subtle changes in approach, using an attribute-based rather than element-based XML list, and tweaking the XQuery shredding. The result was performance and scalability that surpassed all other techniques. I asked Phil how quickly he would have arrived at the real breakthrough on his own. His candid answer was "never". Both are great examples of the power of Community learning and the latter in particular the importance of being brave enough to parade one's ignorance. Perhaps Jeff Moden will accept the string-splitting gauntlet one more time. To quote the great man: you've just got to love this community! If you've an interesting tale to tell about being helped to a significant breakthrough for a problem by the community, I'd love to hear about it. Cheers, Tony.

  • Is monkeypatching considered good programming practice?

    - by vartec
    I've been under impression, that monkeypatching is more in quick and dirty hack category, rather than standard, good programming practice. While I'd used from time to time to fix minor issues with 3rd party libs, I considered it temporary fix and I'd submit proper patch to the 3rd party project. However, I've seen this technique used as "the normal way" in mainstream projects, for example in Gevent's gevent.monkey module. Has monkeypatching became mainstream, normal, acceptable programming practice? See also: "Monkeypatching For Humans" by Jeff Atwood

  • WebLogic Server Weekly for March 26th, 2012: WLS 1211 Update, Java 7 Certification, Galleria, WebLogic for DBAs, REST and Enterprise Architecture, Singleton Services

    - by Steve Button
    WebLogic Server 12c Certified with Java 7 for Production Use WebLogic Server 12c (12.1.1) has been certified with JDK 7 for development usage since December and we have now completed JDK 7 certification for use with production systems. In doing so, we have updated the WebLogic Server 12c (12.1.1) distributions incorporating fixes associated with JDK 7 support as well as some bundled patches that address several issues that have been discovered since the initial release. These updated distributions are available for download from OTN and will be beneficial for all WebLogic Server 12c (12.1.1) users in general. What's New Release Notes Download Here! Updated Oracle WebLogic Server 12.1.1.0 distribution Never one to miss a trick, Markus Eisele was one of the first to notice the WebLogic Server 12c update and post a blog about it. Sources told me that as of Friday last week you have an updated version of WebLogic Server 12c on OTN. http://blog.eisele.net/2012/03/updated-oracle-weblogic-server-12110.html Using WebLogic Server 12c with Java 7 - Video To illustrate the use of Java 7 with WebLogic Server 12c, I put together a screen cam showing the creation of a domain using Java 7 and then build and deploy a simple web application that uses Java 7 syntax to show it working. Ireland OUG Presentation: WebLogic for DBAs Simon Haslam posted his slides from a presentation he gave Dublin on 21/3/12 at the OUG Ireland conference. In this presentation, he explains the core concepts and ideas behind WebLogic Server, walks through an installation and offers some tips and common gotcha's to avoid. Simon also covers some aspects of installing and use Enterprise Manager 12c. Note: I usually install the JVM and use the generic .jar installer rather than using an installer bundled with a JVM. http://www.slideshare.net/Veriton/weblogic-for-dbas-10h Slightly Retro: Jeff West on Enterprise Architecure and REST In this weeks flashback, we look at Jeff West's blog from early 2011 where he provides some thoughtful opinions on enterprise architecture and innovation, then jumps into his views on REST. After I progressed in my career and did more team-leading and architecture type roles I was ‘educated’ on what it meant to have Asynchronous and Long-Running processes as part of your Enterprise Application architecture. If I had a synchronous process then I needed a thread available to service the request and then provide the response. https://blogs.oracle.com/jeffwest/entry/weblogic_integration_wli_web_services_and_soap_and_rest_part_1 Starting Managed Servers without an Administration Server using Node Manager and WLST Blogger weblogic-tips shows how to start a managed server without going through the Administration Server, using the Node Manager and WLST. Connect WLST to a Node Manager by entering the nmConnect command. http://www.weblogic-tips.com/2012/02/18/starting-managed-servers-without-an-administration-server-using-node-manager-and-wlst/ Using WebLogic Server Singleton Services WebLogic Server has supported the notion of a Singleton Service for a number of releases, in which WebLogic Server will maintain a single instance of a configured singleton service on one managed server within a cluster. This blog demonstrates how the singleton service can be accessed and used from applications deployed on the cluster. http://buttso.blogspot.com.au/2012/03/weblogic-server-singleton-services.html

  • The JDEdwards EnterpriseOne PreSales University

    - by Julien Haye
    Istanbul NOV 5-9 Wednesday, NOV 7 - It is raining outside and I am sitting in my hotel room (#106) in Istanbul and create my first blog entry. Today this blog was enabled and I am excited to have the ability to share my (first) thoughts with the EMEA JDE Partner Community. I am here in Istanbul because we are currently running the JDEdwards PreSales University Event series. This PreSales University is an established event series which we deliver the fifth time now and the first time in the ECEMEA region. Delegates value the openness and competence from the Product Strategy and Product Development Team from Denver and India. Together with the regional Oracle PreSales team we had very valuable discussions around product features and functions and about the business value of the new delivered applications and tools. Additionally the event provides endless opportunities to exchange ideas with other JD Edwards Partner and the Oracle PreSales Team. With its focus on sharing and learning, best practice, user experience and transforming technologies, delegates will leave this event with an abundance of new ideas and best practices to try for your coming projects and existing customer implementations. A day out of the office gives delegates a chance to gain a new perspective on their business processes. Everybody sees better ways of working just by being immersed in an environment where the focus is on using products more effectively. Apps Track: Highly concentrated participants in Istanbul listening to Jeff Erickson presenting the news about OneView Reporting. Jeff: We believe “The things you said”. The event is organized into two tracks, one for Apps and one for Tech. Everybody was able to learn new features and functions and how to position this products. The focus was on the new Apps release 9.1 and Tools Release 9.1.2 and their Value Propositions. For all topics hands-on exercises has been given to the participants. Even very experienced senior consultants did learn a lot from this event. In total we have 55 people registered and we still have some more content to deliver. By the way: Istanbul is a nice place to be. I already booked my next trip to this beautiful city. In two weeks we deliver the JD Edwards EECIS Executive Forum again in Istanbul. Once again a tough Agenda. I will let you know if I had the ability to have a walk outside and see a bit more of this beautiful city. At least I expect to have a different room number. Many greetings Hartmut WieseOracle Alliances & Channels EMEA

  • What dangers await if I block non-standard, non-major-usa search engine bots from my USA only website?

    - by Ryan
    I noticed tons of bandwidth being used by non-USA search engine bots, so I began blocking them in an effort to save bandwidth and cpu cycles for actual users and the search engines they come from (Google, Bing, Yahoo, Ask, etc.). Other than potentially losing some international traffic (which isn't really important to us since all of our content is very USA-centric), what additional dangers should I be concerned about?
