• Pagination for product listing, what to use? "canonical" or "rel-prev-next" or do nothing?

  - by Jayapal Chandran

  I want to make sure my product listing is 10 products per page which are not in a series (link). They have explained how to use canonical or rel prev for pagination when a long page has been divided into multiple page and the multiple pages becomes a series were as my condition is not that. They are unique listing which are not related to each listing... All the listing links leads to a product profile page. So lets say my site is all about cars and I have a Used Audi page with 1000 Audi's for sale. There are 10 used audi cars on each page so there's 100 pages in the series. If I start to utilise Rel="prev" and rel="next" should I set page 2 onwards as index,follow or noindex,follow? The content on Page 2 all the way to 100 only changes ever so slightly as different cars will be for sale on different pages but from a "Panda" point of view the pages are incredibly similar as they'd hold the same meta data as page 1 in the series along with duplicate reviews & news etc. I want Page 1 in the series as the Main page for Google to send users too and I don't see the point in Google indexing page 2 100. What's everyone's view on this? Lastly with the rel="canonical" tag should page 2 to 100 all point back to page 1 in the series or the individual page itself? E.G: /used-audi/page-3/.

• With Choice Comes Complexity

  - by BuckWoody

  "Complex" may be defined as "Having many steps, details or parts." Many of Microsoft's products, including SQL Server, can be complex. I'm stating what most data professionals already know - there's usually multiple ways to do things in SQL Server. For instance, to import some data into a table you can use graphical tools, SQLCMD, bcp, SQL Server Integration Services, BULK INSERT, even PowerShell, just to name a few tools at your disposal. That's really not the issue, though. The bigger issue is that there are normally multiple thought-processes, or methods, that you have available for a task. That's both a strength and a weakness. If things were more simple, you would have fewer choices. Sometimes that's a good thing. Just tell me what I need to do and I'll do it. However, your particular situation may not fit that tool or process, so having more options increases your ability to get your job done the way you need to do it. On the other hand, that's more for you to learn, which is harder. There's another side of this benefit/difficulty that you need to be aware of. Even if you're quite good at what you do, keep in mind that the way you know how to do something may not be the only way to do it. Keep your mind open to new possibilities, and most importantly - to new knowledge. SQL Server professionals teach me something new every day. So embrace the complexity - on balance, it's a good thing! Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• What is the best way to render a 2d game map?

  - by Deukalion

  I know efficiency is key in game programming and I've had some experiences with rendering a "map" earlier but probably not in the best of ways. For a 2D TopDown game: (simply render the textures/tiles of the world, nothing else) Say, you have a map of 1000x1000 (tiles or whatever). If the tile isn't in the view of the camera, it shouldn't be rendered - it's that simple. No need to render a tile that won't be seen. But since you have 1000x1000 objects in your map, or perhaps less you probably don't want to loop through all 1000*1000 tiles just to see if they're suppose to be rendered or not. Question: What is the best way to implement this efficiency? So that it "quickly/quicker" can determine what tiles are suppose to be rendered? Also, I'm not building my game around tiles rendered with a SpriteBatch so there's no rectangles, the shapes can be different sizes and have multiple points, say a curved object of 10 points and a texture inside that shape; Question: How do you determine if this kind of objects is "inside" the View of the camera? It's easy with a 48x48 rectangle, just see if it X+Width or Y+Height is in the view of the camera. Different with multiple points. Simply put, how to manage the code and the data efficiently to not having to run through/loop through a million of objects at the same time.

• Is it possible to store playlists in music file metadata?

  - by Ryan Thompson

  I have been trying to think of a way to store my playlists completely independently from any one music player, and I think that one way to do this would be to use each song's tags to store the list of playlists in which that song belongs. For example, if song1.mp3 and song2.flac both belong in the "Cool Songs" playlist, then I would add to each of them a tag called "Playlist" with a value of "Cool Songs". To access the "Cool Songs" playlist in my music player, I simply search for songs where the "Playlist" tag has a value of "Cool Songs". Obviously, I would need a music player that allows me to manipulate arbitrary tags on any music format, including multiple instances of the same tag (so that songs can be in multiple playlists). Instead of creating playlists, I create "saved searches" or whatever the music player calls them, that search for the appropriate playlist tag. Is this scheme possible, and how many music player programs would support such a scheme?

• Generalist Languages: Dying or Alive and Well?

  - by dsimcha

  Around here, it seems like there's somewhat of a consensus that generalist programming languages (that try to be good at everything, support multiple paradigms, support both very high- and very low-level programming), etc. are a bad idea, and that it's better to pick the right tool for the job and use lots of different languages. I see three major areas where this is flawed: Interfacing multiple languages is always at least a source of friction and is sometimes practically impossible. How severe a problem this is depends on how fine-grained the interfacing is. Near the boundary between the two languages, though, you're basically limited to the intersection of their features, and you have to care about things like binary interfaces that you usually wouldn't. Passing complex data structures (i.e. not just primitives and arrays of primitives) between languages is almost always a hassle. Furthermore, shifting between different syntaxes, different conventions, etc. can be confusing and annoying, though this is a fairly minor complaint. Requirements are never set in stone. I hate picking a language thinking it's the right tool for the job, then realizing that, when some new requirement surfaces, it's actually a terrible choice for that requirement. This has happened to me several times before, usually when working with languages that are very slow, very domain specific and/or has very poor concurrency/parallelism support. When you program in a language for a while, you start to build up a personal toolbox of small utility functions/classes/programs. The value of these goes drastically down if you're forced to use a different language than the one you've accumulated all this code in. What am I missing here? Why shouldn't more focus be placed on generalist languages? Are generalist languages as a category dying or alive and well?

• Limitations of the SharePoint join using CAML

  - by ybbest

  Limitation One In SharePoint 2010, you can join the primary list to a foreign list and include more than one field from the foreign list. However, the limitation is that the included fields from foreign list have to be the following type: Calculated (treated as plain text) ContentTypeId Counter Currency DateTime Guid Integer Note (one-line only) Number Text The above limitation also explains why you cannot include some types of the fields from the remote list when creating a lookup. Limitation Two When using CAML query to join SharePoint lists, there can be joins to multiple lists, multiple joins to the same list, and chains of joins. However, the limitations are only inner and left outer joins are permitted and the field in the primary list must be a Lookup type field that looks up to the field in the foreign list. Limitation Three The support for writing the JOIN query in CAML is very limited.I have to hand-code the CAML query to join the lists,not fun at all.Although some blogs post mentioned about using LINQ to SharePoint and get the CAML code from there , but I never get it to work.You can check this blog post  for this.Let me know if it works for you.

• New Dell Vostro 3550 will not boot into Live CD

  - by rich97

  I've been trying to install Ubuntu and/or it's derivatives on my new Dell Vostro 3550 but I'm finding it impossible to boot into the live CD environment. Here are the things I've already tried: Booting from multiple versions of multiple distributions (Ubuntu 10.10, Ubuntu 11.04, Mint 11, Mint 10) Booting from a Live USB created with unetbootin, the Linux Mint startup disk creator, the universal USB creator and dd of=linuxmint.***.iso if if=/dev/sdx. Burning a CD and booting from the internal CD drive. In the case of the USB keys with the latest versions of Ubuntu it gets to the page where I can select a boot option, but after selecting an option the screen goes black, even the back light turns off. With the older distributions the screen stays on but it starts loading and then just hangs. The CDs don't even try to boot. It starts spinning but then falls back to the default Windows install. The only way I've got it to work so far is with Wubi, but that's hardly ideal. I'd like to have two separate physical partitions with a /home and /. Any help is appreciated. Thank you.

• Can Vagrant point to a directory of Puppet manifests for execution?

  - by SeligkeitIstInGott

  I am using Vagrant to jump start some initial Puppet config and am confused on how to include/run multiple manifests (other than just site.pp) in the puppet execution workflow without making the extra manifests into modules and including them that way. In the puppet manifests directory that I point Vagrant to (see below) I have two manifests that I want executed: site.pp and hierasetup.pp. config.vm.provision "puppet" do |puppet| puppet.manifests_path = "puppet_files/manifests" puppet.module_path = "puppet_files/modules" puppet.manifest_file = "site.pp" puppet.options = "--verbose --debug" end Currently I am having site.pp be the manifest that calls hierasetup.pp. My site.pp looks like this: File { owner => 'root', group => 'root', mode => '0644', } import "hierasetup.pp" include jboss But I get this error about the deprecation of "import": Warning: The use of 'import' is deprecated at /tmp/vagrant-puppet-1/manifests/site.pp:33. See http://links.puppetlabs.com/puppet-import-deprecation (at grammar.ra:610:in `_reduce_190') According to the referenced URL under "Things to try instead" it says "To keep your node definitions in separate files, specify a directory as your main manifest". Further this puppet doc on main manifests says: "Recommended: If you’re using the main manifest heavily instead of relying on an ENC, consider changing the manifest setting to $confdir/manifests. This lets you split up your top-level code into multiple files while avoiding the import keyword. It will also match the behavior of simple environments." It appears that Puppet can reference an entire directory instead of just a specific manifest file, such that I would expect that Vagrant would make a provision for this and allow me to drop the "puppet.manifest_file = "site.pp" line and point to the parent directory instead in which all the *.pp files there will be executed. However removing that line in Vagrant merely generates a complaint about an expected "default.pp" in its stead: puppet provisioner: * The configured Puppet manifest is missing. Please specify a path to an existing manifest: /some/path/puppet_files/manifests/default.pp So: Firstly, do I understand the "new" (non-import) way of calling multiple manifests correctly, in that a directory is to be pointed to in which all the *.pp files inside it will be executed? And secondly, has Vagrant "caught up" with this new change to accommodate the referencing of directories in conjunction with Puppet's deprecation of "import"? Update: Thanks to Shane the issue with #2 (Vagrant's code not being caught up to allow pointing to puppet manifest directories) was reported on Vagrant's GitHub issue tracker site and has since been patched: https://github.com/mitchellh/vagrant/issues/4169

• Parallelize incremental processing in Tabular #ssas #tabular

  - by Marco Russo (SQLBI)

  I recently came in a problem trying to improve the parallelism of Tabular processing. As you know, multiple tables can be processed in parallel, whereas the processing of several partitions within the same table cannot be parallelized. When you perform an incremental update by adding only new rows to existing table, what you really do is adding rows to a partition, so adding rows to many tables means adding rows to several partitions. The particular condition you have in this case is that every partition in which you add rows belongs to a different table. Adding rows implies using the ProcessAdd command; its QueryBinding parameter specifies a SQL syntax to read new rows, otherwise the original query specified for the partition will be used, and it could generate duplicated data if you don’t have a dynamic behavior on the SQL side. If you create the required XMLA code manually, you will find that the QueryBinding node that should be part of the ProcessAdd command has to be moved out from ProcessAdd in case you are using a Batch command with more than one Process command (which is the reason why you want to use a single batch: run multiple process operations in parallel!). If you use AMO (Analysis Management Objects) you will find that this combination is not supported, even if you don’t have a syntax error compiling the code, but you might obtain this error at execution time: The syntax for the 'Process' command is incorrect. The 'Bindings' keyword cannot appear under a 'Process' command if the 'Process' command is a part of a 'Batch' command and there are more than one 'Process' commands in the 'Batch' or the 'Batch' command contains any out of line related information. In this case, the 'Bindings' keyword should be a part of the 'Batch' command only. If this is happening to you, the best solution I’ve found is manipulating the XMLA code generated by AMO moving the Binding nodes in the right place. A more detailed description of the issue and the code required to send a correct XMLA batch to Analysis Services is available in my article Parallelize ProcessAdd with AMO. By the way, the same technique (and code) can be used also if you have the same problem in a Multidimensional model.

• An Actionable Common Approach to Federal Enterprise Architecture

  - by TedMcLaughlan

  The recent “Common Approach to Federal Enterprise Architecture” (US Executive Office of the President, May 2 2012) is extremely timely and well-organized guidance for the Federal IT investment and deployment community, as useful for Federal Departments and Agencies as it is for their stakeholders and integration partners. The guidance not only helps IT Program Planners and Managers, but also informs and prepares constituents who may be the beneficiaries or otherwise impacted by the investment. The FEA Common Approach extends from and builds on the rapidly-maturing Federal Enterprise Architecture Framework (FEAF) and its associated artifacts and standards, already included to a large degree in the annual Federal Portfolio and Investment Management processes – for example the OMB’s Exhibit 300 (i.e. Business Case justification for IT investments).A very interesting element of this Approach includes the very necessary guidance for actually using an Enterprise Architecture (EA) and/or its collateral – good guidance for any organization charged with maintaining a broad portfolio of IT investments. The associated FEA Reference Models (i.e. the BRM, DRM, TRM, etc.) are very helpful frameworks for organizing, understanding, communicating and standardizing across agencies with respect to vocabularies, architecture patterns and technology standards. Determining when, how and to what level of detail to include these reference models in the typically long-running Federal IT acquisition cycles wasn’t always clear, however, particularly during the first interactions of a Program’s technical and functional leadership with the Mission owners and investment planners. This typically occurs as an agency begins the process of describing its strategy and business case for allocation of new Federal funding, reacting to things like new legislation or policy, real or anticipated mission challenges, or straightforward ROI opportunities (for example the introduction of new technologies that deliver significant cost-savings).The early artifacts (i.e. Resource Allocation Plans, Acquisition Plans, Exhibit 300’s or other Business Case materials, etc.) of the intersection between Mission owners, IT and Program Managers are far easier to understand and discuss, when the overlay of an evolved, actionable Enterprise Architecture (such as the FEA) is applied.  “Actionable” is the key word – too many Public Service entity EA’s (including the FEA) have for too long been used simply as a very highly-abstracted standards reference, duly maintained and nominally-enforced by an Enterprise or System Architect’s office. Refreshing elements of this recent FEA Common Approach include one of the first Federally-documented acknowledgements of the “Solution Architect” (the “Problem-Solving” role). This role collaborates with the Enterprise, System and Business Architecture communities primarily on completing actual “EA Roadmap” documents. These are roadmaps grounded in real cost, technical and functional details that are fully aligned with both contextual expectations (for example the new “Digital Government Strategy” and its required roadmap deliverables - and the rapidly increasing complexities of today’s more portable and transparent IT solutions.  We also expect some very critical synergies to develop in early IT investment cycles between this new breed of “Federal Enterprise Solution Architect” and the first waves of the newly-formal “Federal IT Program Manager” roles operating under more standardized “critical competency” expectations (including EA), likely already to be seriously influencing the quality annual CPIC (Capital Planning and Investment Control) processes.  Our Oracle Enterprise Strategy Team (EST) and associated Oracle Enterprise Architecture (OEA) practices are already engaged in promoting and leveraging the visibility of Enterprise Architecture as a key contributor to early IT investment validation, and we look forward in particular to seeing the real, citizen-centric benefits of this FEA Common Approach in particular surface across the entire Public Service CPIC domain - Federal, State, Local, Tribal and otherwise.

DevOps is a response to the interdependence of software development and IT operations. It aims to help an organization rapidly produce software products and services. That definition of DevOps is the – what. The “why” is even easier. Standardized development methodology, clear communication and documented processes supported by a standards-based, proven middleware platform improves application development and management cycles, brings agility and provides greater availability and security to your IT infrastructure.

• Storing data for use on Android and Windows Applications

  - by Andy Mepham

  I posted this last night on StackOverflow and was advised to move it over to StackExchange, thank you for taking a moment to look at my question. I'm developing a project proposal for my final year project at University and as I aim to use programming languages I am currently not too familiar with I'm looking for some guidance - I can't include details of my project but hopefully you will understand what I'm after. I'm going to be creating an Android application (in Java) and a Windows Application (in C#) that will ideally access, query and update a remotely hosted Database or set of XML files (this would most likely be over the Internet). I've done some looking around the internet and SQLite seems like a safe-bet for cross-platform manipulation of the database; however I would like to keep the system as lightweight as possible and I'm wondering whether XML files may provide a better alternative? Anyone out there that has experience using SQLite and/or remotely hosted XML for the purposes of Android and/or C# development that could point me in the right direction? If there is an alternative solution other than those I have mentioned I would be interested to hear about them too. Thank you for taking the time to read my question. Edit: The purpose of this application is for a small scale business, the data source would not need to be updated by more than one source but may be view from multiple sources (i.e. through multiple phones and a desktop PC). The database wouldn't be updating masses of data at a time (most likely single rows of a few tables at the most).

• IE does not send NTLM domain

  - by Buddy Casino

  Hi! I have a problem with NTLM single-sign-on with IE8. We've got multiple domain controllers and users from multiple domains that we try to authenticate to a web application via NTLMv1 passthru. Somehow IE fails to send the user's domain in the NTLM Type 1 message. This has the effect that the webapp can not match users properly to their domain controllers, resulting in failed logon attempts, because a user from domain X tries to authenticate to domain controller Y. This problem does not occur with Firefox, as it always sends the correct domain header. So: how do I get IE to send the domain in the NTLM header? Grateful for any help, Michael

• Building a Redundant / Distributed Application

  - by MattW

  This is more of a "point me in the right direction" question. My team of three and I have built a hosted web app that queues and routes customer chat requests to available customer service agents (It does other things as well, but this is enough background to illustrate the issue). The basic dev architecture today is: a single page ajax web UI (ASP.NET MVC) with floating chat windows (think Gmail) a backend Windows service to queue and route the chat requests this service also logs the chats, calculates service levels, etc a Comet server product that routes data between the web frontend and the backend Windows service this also helps us detect which Agents are still connected (online) And our hardware architecture today is: 2 servers to host the web UI portion of the application a load balancer to route requests to the 2 different web app servers a third server to host the SQL Server DB and the backend Windows service responsible for queuing / delivering chats So as it stands today, one of the web app servers could go down and we would be ok. However, if something would happen to the SQL Server / Windows Service server we would be boned. My question - how can I make this backend Windows service logic be able to be spread across multiple machines (distributed)? The Windows service is written to accept requests from the Comet server, check for available Agents, and route the chat to those agents. How can I make this more distributed? How can I make it so that I can distribute the work of the backend Windows service can be spread across multiple machines for redundancy and uptime purposes? Will I need to re-write it with distributed computing in mind? I should also note that I am hosting all of this on Rackspace Cloud instances - so maybe it is something I should be less concerned about? Thanks in advance for any help!

• How to configure machines in a public subnet with two gateways?

  - by Shtééf

  We have a single public /24 subnet, with a BGP router as the primary gateway. Now I'm interested in configuring a second router for redundancy. How do I deal with multiple gateways on the servers in our public subnet? I found some other questions related to multiple gateways that seem to deal with NAT set-ups. In my situation, the servers all have public routed IP-addresses. So from what I can tell, it doesn't really matter which route incoming or outgoing packets take. But I figure the servers need some way of telling when one of the gateways is down, and route around it? Is this accomplished with protocols such as OSPF? And do I need to deploy this on all my servers?

• Mastering snow and Java development at jDays in Gothenburg

  - by JavaCecilia

  Last weekend, I took the train from Stockholm to Gothenburg to attend and present at the new Java developer conference jDays. It was professionally arranged in the Swedish exhibition hall close to the amusement park Liseberg and we got a great deal out of the top-level presenters and hallway discussions. Understanding and Improving Your Java Process Our main purpose was to spread information on JVM and our monitoring tools for Java processes, so I held a crash course in the most important terms and concepts if you want to affect the performance of your Java process. From the beginning - the JVM specification to interpretation of heap usage graphs. For correct analysis, you also need to understand something about process memory - you need space for the Java heap (-Xms for initial size and -Xmx for max heap size), but the process memory also contain the thread stacks (to a size of -Xss), JVM internal data structures used for keeping track of Java objects on the heap, method compilation/optimization, native libraries, etc. If you get long pause times, make sure to monitor your application, see the allocation rate and frequency of pause times.My colleague Klara Ward then held a presentation on the Java Mission Control product, the profiling and diagnostics tools suite for HotSpot, coming soon. The room was packed and very appreciated, Klara demonstrated four different scenarios, e.g. how to diagnose and fix latencies due to lock contention for logging.My German colleague, OpenJDK ambassador Dalibor Topic travelled to Sweden to do the second keynote on "Make the Future Java". He let us in on the coming features and roadmaps of Java, now delivering major versions on a two-year schedule (Java 7 2011, Java 8 2013, etc). Also letting us in on where to download early versions of 8, to report problems early on. Software Development in teams Being a scout leader, I'm drilled in different team building and workshop techniques, creating strong groups - of course, I had to attend Henrik Berglund's session on building successful teams. He spoke about the importance of clear goals, autonomy and agreed processes. Thomas Sundberg ended the conference by doing live remote pair programming with Alex in Rumania and a concrete tips for people wanting to try it out (for local collaboration, remember to wash and change clothes). Memory Master Keynote The conference keynote was delivered by the Swedish memory master Mattias Ribbing, showing off by remembering the order of a deck of cards he'd seen once. He made it interactive by forcing the audience to learn a memory mastering technique of remembering ten ordered things by heart, asking us to shout out the order backwards and we made it! I desperately need this - bought the book, will get back on the subject. Continuous Delivery The most impressive presenter was Axel Fontaine on Continuous Delivery. Very well prepared slides with key images of his message and moved about the stage like a rock star. The topic is of course highly interesting, how to create an infrastructure enabling immediate feedback to developers and ability to release your product several times per day. Tomek Kaczanowski delivered a funny and useful presentation on good and bad tests, providing comic relief with poorly written tests and the useful rules of thumb how to rewrite them. To conclude, we had a great time and hope to see you at jDays next year :)

• CPU?: Not responding

  - by James

  I'm attempting to build a system for co-location. I've been running into issues while trying to install CentOS 6.3 System Specs: Motherboard: ASUS m5a99x Process: AMD FX-8120 (8-core Bulldozer) Memory: 2x 4gb G-Skill 2133 running at 1600 I keeps giving me an error message: CPU1: Not Responding. CPU2: Not Responding. CPU3: Not Responding. CPU4: Not Responding. CPU5: Not Responding. CPU6: Not Responding. Then it instantly restarts. I have tried installing it from USB, Multiple DVDs, Multiple Distros. I have also in the bios attempted to disable cores. I was able to disable 2/3 4/5 6/7. I have also ensured that there is zero overclocking. The system works fine in a windows environment. I'm out of ideas.

• Outlook 2010: When sending message on behalf of someone else, store that message in the other person's Sent Items folder

  - by Helge Klein

  We have an e-mail account for support purposes which is tended to by multiple members of the team. When answering a support e-mail we obviously choose the support account as sender. Still, the answer is not stored in the support account's Sent Items folder, but in the Sent Items of the person actually answering. This behavior, which seems to be by design, prevents others from gaining access to the entire conversation and potentially causes multiple answers. I am looking for an automated way of moving e-mails sent on behalf of someone else to that person's Sent Items folder. I tried to create a rule for this but could not find the right setting.

• Top 5 Reasons to Invest in Enterprise 2.0 Technologies

  - by kellsey.ruppel(at)oracle.com

  In 2010, Oracle's portal, content management, and collaboration solutions evolved rapidly, supported by increasingly deep integrations across Oracle Fusion Middleware and the entire Oracle stack. In light of these developments, we asked Vince Casarez, vice president of Enterprise 2.0 product management, for his top five reasons to invest in Enterprise 2.0 (E2.0) technologies--including real-world examples of businesses already realizing the benefits of next-generation E2.0 technologies. 1. Provide a modern user experience As E2.0 technologies gain widespread adoption, customers and employees expect intuitive Web experiences that are both interactive and community-based. By partnering with Oracle, Alcatel-Lucent Enterprise Group is already making that happen. With 76,000 employees and operations in more than 100 countries, the company wanted a streamlined, personalized user experience with more relevant content in fewer clicks. Working with Oracle, they created a global support portal that supports personalization and integration with Oracle Business Intelligence Enterprise Edition and Oracle E-Business Suite--and drives collaboration with tools such as wikis, blogs, and forums. Learn more about Alcatel-Lucent Enterprise Group's Global Support Portal in this Webcast. 2. Improve productivity and collaboration As E2.0 technologies mature, Oracle anticipates companies moving beyond the idea of simply creating yet another Facebook-like destination for its employees, and instead shaping work environments around specific business tasks. After rapid growth--both organic and through acquisition--construction and infrastructure services leader Balfour Beatty found itself with multiple homegrown intranet sites with very minimal content-sharing capabilities. Today, thanks to Oracle WebCenter Suite, Oracle WebCenter Spaces, Oracle WebCenter Services, and Oracle Universal Content Management, Balfour Beatty is benefiting from collaborative workspaces, a central place to use and work with documents, and unified search across content. 3. Leverage business processes and applications Modern portals are now able to integrate users, content, and business processes in unprecedented ways. To take advantage of these new possibilities, leading dairy provider Land O'Lakes has implemented a fully integrated ERP solution together with Oracle's ECM platform. As a result, Land O'Lakes has been able to achieve better information management and compliance, increased adoption rates for enterprise tools, and increased business process efficiency thanks to more effective information sharing and collaboration. 4. Enhance customer and supplier relationships Companies have begun to move beyond the idea that E2.0 simply means enabling customer reviews or embedding chat functionality. They are taking E2.0 to the next level and providing interactive experiences for their customers. For example, to enhance customer and supplier relationships, Wind River, a global leader in device software optimization, successfully partnered with Oracle to: Integrate ERP and ECM content to provide customers the latest and most relevant support information for products they own Enable customers to personalize their support experience and receive updates regarding patches, application notes, and other relevant content Enable discussions, wikis, and blogs for more efficient collaboration 5. Increase business visibility and responsiveness By strategically embedding collaboration and communication tools into specific business contexts, companies significantly increase visibility into changing business conditions--and can respond much more agilely. Texas A&M University System--one of the largest systems of higher education in the U.S.--partnered with Oracle to create a unified repository that would enable the retrieval of research and grant data from disparate systems via an Enterprise 2.0 user interface. By enabling researchers to customize their own portals with easy-to-use tools, they have also been able to significantly reduce their reliance on the IT department. Learn how other Oracle customers are leveraging Enterprise 2.0 technologies.

• Designing business objects, and gui actions

  - by fozz

  Developing a product ordering system using Java SE 6. The previous implementations used combo boxes, text fields, and check boxes. Preforming validation on action events from the GUI. The validation includes limiting existing combo boxes items, or even availability. The issue in the old system was that the action was received and all rules were applied to the entire business object. This resulted in a huge event change as options were changed multiple times. To be honest I have no idea how an infinite loop wasn't produced. Through the next iteration I stepped in and attempted to limit the chaos by controlling the order in which the selections could be made. Making configuration of BO's a top down approach. I implemented custom box models, action events, beans/binding, and an MVC pattern. However I still am unable to fully isolate action even chains. I'm thinking that I've approached the whole concept backwards in an attempt to stay closest to what was already in place. So the question becomes what do I design instead? I'm currently considering an implementation of Interfaces, Beans, Property Change Listeners to manage the back and forth. Other thoughts were validation exceptions, dynamic proxies.... I'm sure there are a ton of different ways. To say that one way is right is crazy, and I'm sure it will take a blending of multiple patterns. My knowledge of swing/awt validation is limited, previously I did backend logic only. Other considerations are were some sort of binding(jgoodies or otherwise) to directly bind GUI state to BO's.

• Converting a bounded knapsack problem to 0/1 knapsack problem

  - by Ants

  I ran across a problem where goal was to use dynamic programming (instead of other approaches). There is a distance to be spanned, and a set of cables of different lengths. What is the minimum number of cables needed to span the distance exactly? To me this looked like a knapsack problem, but since there could be multiples of a particular length, it was a bounded knapsack problem, rather than a 0/1 knapsack problem. (Treat the value of each item to be its weight.) Taking the naive approach (and not caring about the expansion of the search space), the method I used to convert the bounded knapsack problem into a 0/1 knapsack problem, was simply break up the multiples into singles and apply the well-known dynamic programming algorithm. Unfortunately, this leads to sub-optimal results. For example, given cables: 1 x 10ft, 1 x 7ft, 1 x 6ft, 5 x 3ft, 6 x 2ft, 7 x 1ft If the target span is 13ft, the DP algorithm picks 7+6 to span the distance. A greedy algorithm would have picked 10+3, but it's a tie for minimum number of cables. The problem arises, when trying to span 15ft. The DP algorithm ended up picking 6+3+3+3 to get 4 cables, while the greedy algorithm correctly picks 10+3+2 for only 3 cables. Anyway, doing some light scanning of converting bounded to 0/1, it seems like the well-known approach to convert multiple items to { p, 2p, 4p ... }. My question is how does this conversion work if p+2p+4p does not add up to the number of multiple items. For example: I have 5 3ft cables. I can't very well add { 3, 2x3, 4x3 } because 3+2x3+4x3 5x3. Should I add { 3, 4x3 } instead? [I'm currently trying to grok the "Oregon Trail Knapsack Problem" paper, but it currently looks like the approach used there is not dynamic programming.]

• How to delete just one LINE of text (NOT a table-row!) with a single KEYBOARD shortcut in Microsoft Office Word 2010?

  - by Sk8erPeter

  Are there any shortcuts to delete just one row (which is NOT a table row, just a single row in a text) in Microsoft Office Word 2010? If not, how can I assign one to do it? In worst case, can I make a macro (in VB) which could do the same with a custom shortcut? To clarify my problem: I would like to avoid multiple clicks and/or pushing multiple buttons, even if I click in the middle of the line of text. :) For example, in Notepad++ I can delete the entire current line with Ctrl+L, in NetBeans, I can delete an entire line with Ctrl+E, in Eclipse, I can delete current line with Ctrl+D, etc., where it doesn't really matter where my mouse cursor is actually... so there are these simple solutions, which I look for in Word too. It really would simplify my work in huge documents.
