• what is the Web development process efficiency judgment criteria

  - by Ahmed safan

  I'm working as a web developer and I want to be able to determine if I'm efficient. Does this include the how long it take to accomplish tasks such as: Server side code for the site logic with one language or multiple php,asp,asp.net. Client side code like javascript with jquery for ajax, menus and other interactivity Page layout, html, css (color, fonts (but I have no artistic sense!)) The needs of the site and how it will work (planning) How can i judge how long it will take to complete a website? The site has CMS for adding and editing news, products, articles on the experience of the company. Also, they can edit team work, add Recreational Activities and a logo gallery with compressed psd download, and send messages to cpanel and to email. You are starting from scratch except JQuery and PHPmailer. How can I estimate how long the job will take, and how can I calculate the required time to finish any new projects? I'm so sorry for many scattered questions, but I'm in my first experiment and I want to take benefits from the great experience of those who have it.

• You Can&rsquo;t Upload An Empty File To SharePoint 2007 Or SharePoint 2010

  - by Brian Jackett

  The title of this post is pretty self explanatory, but I thought it worth mentioning since I had never run across this rule until just recently.  A few weeks ago I was testing out a new workflow attached to a SharePoint 2007 document library.  I uploaded various file types to ensure all were handled properly.  One of the files I happened to test with was an empty .txt file to which I got the following error.      As you can see from the error message you aren’t allowed to upload a file that is empty.  Fast forward to this week when I was doing some research for my upcoming SharePoint 2010 beta exams.  I remembered that error I got a few weeks ago and decided to try out with SharePoint 2010 as well.  No surprises I got a similar error. Conclusion     Next time you are uploading files to a SharePoint 2007 or 2010 document library, make sure the file is not empty.  Coincidentally when I tweeted about this issue a few friends replied that they had also found this error recently.  I don’t know the internal reasoning why this is prevented but I assume it has something to do with how the blob for the file is stored in the database.  I assume that this would still be the case even if you had Remote Blob Storage (RBS) configured for your farm, but don’t have access to such a farm to confirm.  If anyone reading this does have access and wants to confirm that would be appreciated, just leave a comment.         -Frog Out

• Does it make sense to write a build scripts in C++?

  - by Klaim

  I'm using CMake to generate my projects IDE/makefiles, but I still need to call custom "scripts" to manipulate my compiled files or even generate code. In previous projects I've been using Python and it was OK, but now I'm having serious trouble managing a lot of dependencies in two very big projects I'm working on so I want to minimize the dependencies everywhere. Someone suggested to me to use C++ to write my build scripts instead of adding a language dependency just for that. The projects themeselves already use C++ so there are several advantages that I can see: to build the whole project, only a C++ compiler and CMake would be necessary, nothing else (all the other dependencies are C or C++); C++ type safety (when using modern C++) makes everything easier to get "correct"; it's also the language I know the better so I'm more at ease with it even if I'm able to write some good Python code; potential gain in execution speed (but i don't think it will really be perceptible); However, I think there might be some drawbacks and I'm not sure of the real impact as I didn't try yet: might be longer to write the code (that said I'm not sure because I'm efficient enough in C++ to write something that work quickly, so maybe for this system it wouldn't be so long to write) (compilation time shouldn't be a problem for this case); I must assume that all the text files I'll read as input are in UTF-8, I'm not sure it can be easilly checked at runtime in C++ and the language will not check it for you; libraries in C++ are harder to manage than in scripting languages; I lack experience and forsight so maybe I'm missing advantages and drawbacks. So the question is: does it make sense to use C++ for this? do you have experiences to report and do you see advantages and disadvantages that might be important?

• Should a model binder populate all of the model?

  - by Richard

  Should a model binder populate all of the model, or only the bits that are being posted? For example, I am adding a product in my system and on the form i want the user to select which sites the new product will appear on. Therefore, in my model I want to populate a collection called "AllAvailableSites" to render the checkboxes for the user to choose from. I also need to populate the model with any chosen sites on a post in case the form does not validate, and I need to represent the form showing the initial selections. It would seem that I should let the model binder set the chosen sites on the model, and (once in the controller method) I set the "AllAvailableSites" on the model. Does that sound right? It seems more efficient to set everything in the model binder but someone is suggesting it is not quite right. I am grateful for any advice; I have to say that all the MVC model binding help online seems to cite really simple examples, nothing complicated. Do I really need a GET and a POST version of a method? Can't they just take the same view model? Then I check in my model binder if it is a GET/POST, and populate all the model accordingly.

• Updating an interface to bootstrap

  - by Anagio

  I'm updating a web apps interface to bootstrap. There's a lot of existing CSS and Javascript/jQuery i'll have to migrate, most i'll scrap and use bootstraps. But for parts of the app that use datatables and such all that code has to be migrated. I'm working on a development server. The app has a header.phtml sidebar.phtml and a lot of content area view files. Right now i'm building static versions of view files say the header. I then open my existing header.phtml into notepad++ split screen with the static file and copy over the dynamic code. Then replace the old header.phtml with the one I just made. To make sure the header displayed correctly I had to add all the CSS and JS from bootstrap. This is conflicting with the current CSS styles and some JS conflicts as well. Should I go through the app note what JS I absolutely need what I don't and same with the CSS. Then strip all the CSS/JS from the old app that is not needed so it only has bootstraps and any other critical files and not worry about the way pages look as i'm making progress to updating them. I'd be working on mostly a wireframe of the old site without any styles until I get to applying bootstraps. Is this efficient or is there another way I can get through all these files and update them easily?

• Need Guidance Making HTML5 Canvas Game Engine

  - by Scriptonaut

  So I have some free time this winter break and want to build a simple 2d HTML5 canvas game engine. Mostly a physics engine that will dictate the way objects move and interact(collisions, etc). I made a basic game here: http://caidenhome.com/HTML%205/pong.html and would like to make more, and thought that this would be a good reason to make a simple framework for this stuff. Here are some questions: Does the scripting language have to be Javascript? What about Ruby? I will probably write it with jQuery because of the selecting powers, but I'm curious either way. Are there any great guides you guys know of? I want a fast guide that will help me bust out this engine sometime in the next 2 weeks, hopefully sooner. What are some good conventions I should be aware of? What's the best way to get sound? At the moment I'm using something like this: var audioElement = document.createElement('audio'); audioElement.setAttribute('src', 'paddle_col.wav'); audioElement.load(); I'm interested in making this engine lightweight and extremely efficient, I will do whatever it takes to get great speeds and processing power. I know this question is fairly vague, but I just need a push in the right direction. Thanks :)

• Lightning fast forum based around metadata / tags? [closed]

  - by Dan W

  Possible Duplicate: What Forum Software should I use? I wonder if anything like this exists. I'd like to add a forum to my site, but instead of the usual forum/subforum/sub-subforum structure, I'd like to use a metadata/tag approach where everything exists as a single directory, and where there's a search field at the top which instantly (<0.5 sec) filters the threads to a particular keyword or keywords. Also, as the admin, I would be able to add highly visible buttons at the top, which can be clicked on for the main categories I choose for the forum (nevertheless, users can also add tags to their own threads outside of these default main tags I supply if they wish). This approach, if done properly, is more powerful, efficient, maintenance free, scalable and friendly than a standard forum, so I was hoping someone had the same idea and made something out of it. It couldn't be that hard. I'd want the speed to be up to (or near) the standard of this: http://forum.dlang.org/ Other forums (e.g.: phpBB) are orders of magnitude worse than that in terms of latency (posting or browsing), and I think that is wrong, even in principle ;)

• Best approach to accessing multiple data source in a web application

  - by ced

  I've a base web application developed with .net technologies (asp.net) used into our LAN by 30 users simultanousley. From this web application I've developed two verticalization used from online users. In future i expect hundreds users simultanousley. Our company has different locations. Each site use its own database. The web application needs to retrieve information from all existing databases. Currently there are 3 database, but it's not excluded in the future expansion of new offices. My question then is: What is the best strategy for a web application to retrieve information from different databases (which have the same schema) whereas the main objective performance data access and high fault tolerance? There are case studies in the literature that I can take as an example? Do you know some good documents to study? Do you have any tips to implement this task so efficient? Intuitively I would say that two possible strategy are: perform queries from different sources in real time and aggregate data on the fly; create a repository that contains the union of the entities of interest and perform queries directly on repository;

• geomipmapping using displacement mapping (and glVertexAttribDivisor)

  - by Will

  I wake up with a clear vision, but sadly my laptop card doesn't do displacement mapping nor glVertexAttribDivisor so I can't test it out; I'm left sharing here: With geomipmapping, the grid at any factor is transposable - if you pass in an offset - say as a uniform - you can reuse the same vertex and index array again and again. If you also pass in the offset into the heightmap as a uniform, the vertex shader can do displacement mapping. If the displacement map is mipmapped, you get the advantages of trilinear filtering for distant maps. And, if the scenery is closer, rather than exposing that the you have a world made out of quads, you can use your transposable grid vertex array and indices to do vertex-shader interpolation (fancy splines) to do super-smooth infinite zoom? So I have some questions: does it work? In theory, in practice? does anyone do it? Does this technique have a name? Papers, demos, anything I can look at? does glVertexAttribDivisor mean that you can have a single glMultiDrawElementsEXT or similar approach to draw all your terrain tiles in one call rather than setting up the uniforms and emitting each tile? Would this offer any noticeable gains? does a heightmap that is GL_LUMINANCE take just one byte per pixel(=vertex)? (On mainstream cards, obviously. Does storage vary in practice?) Does going to the effort of reusing the same vertices and indices mean that you can basically fill the GPU RAM with heightmap and not a lot else, giving you either bigger landscapes or more detailed landscapes/meshes for the same bang? is mipmapping the displacement map going to work? On future cards? Is it going to introduce unsurmountable inaccuracies if it is enabled?

• TCO Comparison: Oracle Exadata vs IBM P-Series

  - by Javier Puerta

  Cost Comparison for Business Decision-makersOracle Exadata Database Machine vs. IBM Power SystemsHow to Weigh a Purchase DecisionOctober 2012 Download full report here In this research-based  white paper conducted at the request of Oracle, The FactPoint Group compares the cost of ownership of the Oracle Exadata engineered system to a traditional build-your-own (BYO) solution, in this case an IBM Power 770 (P770) with SAN storage.  The IBM P770 was chosen given it is IBM’s current most popular model, based on FactPoint primary and secondary research and IBM claims, and because at least one of the interviewed customers had specifically migrated from a P770 to Exadata, affording us a more specific data point for comparison. This research found that Oracle Exadata: Can be deployed more quickly and easily requiring 59% fewer man-hours than a traditional IBM Power Systems solution. Delivers dramatically higher performance typically up to 12X improvement, as described by customers, over their prior solution.  Requires 40% fewer systems administrator hours to maintain and operate annually, including quicker support calls because of less finger-pointing and faster service with a single vendor.  Will become even easier to operate over time as users become more proficient and organize around the benefits of integrated infrastructure. Supplies a highly available, highly scalable and robust solution that results in reserve capacity that make Exadata easier for IT to operate because IT administrators can manage proactively, not reactively.  Overall, Exadata operations and maintenance keep IT administrators from “living on the edge.”  And it’s pre-engineered for long-term growth. Finally, compared to IBM Power Systems hardware, Exadata is a bargain from a total cost of ownership perspective:  Over three years, the IBM hardware running Oracle Database cost 31% more in TCO than Exadata.

• How to drastically improve code coverage?

  - by Peter Kofler

  I'm tasked with getting a legacy application under unit test. First some background about the application: It's a 600k LOC Java RCP code base with these major problems massive code duplication no encapsulation, most private data is accessible from outside, some of the business data also made singletons so it's not just changeable from outside but also from everywhere. no business model, business data is stored in Object[] and double[][], so no OO. There is a good regression test suite and an efficient QA team is testing and finding bugs. I know the techniques how to get it under test from classic books, e.g. Michael Feathers, but that's too slow. As there is a working regression test system I'm not afraid to aggressively refactor the system to allow unit tests to be written. How should I start to attack the problem to get some coverage quickly, so I'm able to show progress to management (and in fact to start earning from safety net of JUnit tests)? I do not want to employ tools to generate regression test suites, e.g. AgitarOne, because these tests do not test if something is correct.

• PHP - Making CMS (architecture, etc.)

  - by UnknownProgramer

  I'm in the stage of planning new CMS. Before I used WordPress and other open source CMS for my clients, but I always had to write new modules and even mess with the code in order to do certain things. Which as you understand is not the best thing to do. So I finally decided to make my own CMS to work with, the way I need. But before I start it, I would like to think it trough carefully to ensure that I won't need to rewrite it ground up, just because I forgot to include some feature into architecture or did it wrong. I would like to hear your thoughs and the most important I would like you to suggest me some articles or books on that subject, especially on architecture of such systems. I googled a few good books, but that is not enough. The way I'm planning to do it: PHP5, completely OOP, modules architecture. You make a page and add any modules you need there, but modules are not global, but local to a page so you can make two pages with the same module, but content will be different if you set different "content ID" for these two entities. But it can be set the same, so two pages has the same content of the modules put there. Also I plan to support online storage web service (like amazon S3) for images and files, so I would like to hear your thoughs on it too. Also I have not yet decided how to store language data. I don't want to use DB for that, but I haven't decided yet. Also I think I will support other DB with global DB class and separate DB wrappers for MySQL and other databases. And, well, I would appreciate any other information you can provide for that subject.

• Design guideline for saving big byte stream in c# [migrated]

  - by Praveen

  I have an application where I am receiving big byte array very fast around per 50 miliseconds. The byte array contains some information like file name etc. The data (byte array ) may come from several sources. Each time I receive the data, I have to find the file name and save the data to that file name. I need some guide lines to how should I design it so that it works efficient. Following is my code... public class DataSaver { private static Dictionary<string, FileStream> _dictFileStream; public static void SaveData(byte[] byteArray) { string fileName = GetFileNameFromArray(byteArray); FileStream fs = GetFileStream(fileName); fs.Write(byteArray, 0, byteArray.Length); } private static FileStream GetFileStream(string fileName) { FileStream fs; bool hasStream = _dictFileStream.TryGetValue(fileName, out fs); if (!hasStream) { fs = new FileStream(fileName, FileMode.Append); _dictFileStream.Add(fileName, fs); } return fs; } public static void CloseSaver() { foreach (var key in _dictFileStream.Keys) { _dictFileStream[key].Close(); } } } How can I improve this code ? I need to create a thread maybe to do the saving.

• Direct IO enhancements in OVM Server for SPARC 2.2(a.k.a LDoms2.2)

  - by user12611315

  The Direct I/O feature has been available for LDoms customers since LDoms2.0. Apart from the latest SR-IOV feature in LDoms2.2, it is worth noting a few enhancements to the Direct I/O feature. These are: Support for Metis-Q and Metis-E cards. These cards are highly requested for support and are worth mentioning because they are the only combo cards containing both FibreChannel and Ethernet in the same card. With this support, a customer can have both SAN storage and network access with just one card and one PCIe slot assigned to a logical domain. This reduces cost and helps when there are less number of slots in a given platform. The following are the part numbers for these cards. I have tried to put the platforms on which each card is supported, but this information can get quickly outdated. The accurate information can be found at the Support Document.  Card Name  Part Number  Platforms Metis-Q: StorageTek Dual 8Gb Fibre Channel Dual GbE ExpressModule HBA, QLogic SG-XPCIEFCGBE-Q8-N  SPARC T3-4, T4-4 Metis-E: StorageTek Dual 8Gb Fibre Chanel Dual GbE ExpressModule HBA, Emulex SG-XPCIEFCGBE-E8-N SPARC T3-4, T4-4  Additional cards added to the portfolio of supported cards. This is mainly Powerville based Ethernet cards, the part numbers for these cards as below:  Part Number  Description  7100477 Sun Quad Port GbE PCI Express 2.0 Low Profile Adapter, UTP  7100481 Sun Dual Port GbE PCI Express 2.0 Low Profile Adapter, MMF  7100483 Sun Quad Port GbE PCI Express 2.0 ExpressModule, UTP  7110486 Sun Quad Port GbE PCI Express 2.0 ExpressModule, MMF    Note:  Direct IO feature has a hard dependency on the Root domain(PCIe bus owner, here Primary domain). That is, rebooting the Root domain for any reason may impact the logical domains having PCIe slots assigned with Direct IO feature. So rebooting a root domain need to be carefully managed. Also apply the failure-policy settings as described in the admin guide and release notes to deal with unexpected cases.

• Prevent Looping and Inefficient Rule Executions by C2B2

  - by JuergenKress

  This recipe, taken from the recently published Oracle SOA Suite 11g Performance Cookbook gives guidance on how to avoid rule executions that will loop, potentially indefinitely! We’ll use an inbound XML fact and a local RL fact as an example. Getting ready You’ll need access to a SOA composite containing an Oracle Business Rules component in JDeveloper to apply this recipe. We’ll assume you have an XSD schema with an input type RequestInput containing input and bonus String types, and output String value called output in a type ResponseOutput. These aren’t efficient but serve as an example. We’ll step through adding a rule to a composite and creating an RL fact. How to do it... Open a SOA composite. Right click on the Project and select Business Rules (Service Components), use the search box if it is not immediately available. Give the rule a name and click the green plus icon to add the RequestInput to the input and ResponseOutput to the output types. Read the complete article here.

• Sharing swap space between Windows and Ubuntu

  - by Leftium

  This Linux Swap Space Mini-HOWTO describes how to share swap space between Windows and Linux. Do these instructions still apply to Ubuntu in 2011? How should I modify the steps for Ubuntu? Is there a better approach to sharing swap space? Based on the HOWTO, it seems best to create a dedicated NTFS swap partition: Dedicated so the swap file will be contiguous and remain unfragmented. NTFS so both Windows and Ubuntu can read/write to it. (Or is FAT32 better for this purpose?) Then, configure Ubuntu to prepare the swap space for use by Linux on start up; by Windows on shut down. I want to dual boot Ubuntu and Windows 7 on my X301 laptop. However, my laptop only has a 64 GB SDD, so I would like to conserve as much disk space as possible. update: There is an alternate method using a special driver for Windows that let you use a Linux swap partition for temporary storage like a RAM-disk, but it doesn't seem to be as good...

• Hot Off the Press - Oracle Exadata: A Data Management Tipping Point

  - by kimberly.billings

  Advances in data-management architecture - including CPU, memory, storage, I/O, and the database - have been steady but piecemeal. In this report, Merv Adrian describes how Oracle Exadata not only provides the latest technology in each part of the data-management architecture, but also integrates them under the full control of one vendor with a unified approach to leveraging the full stack. He writes, "the real "secret sauce" of Oracle Exadata V2 is the way in which these technologies complement each other to deliver additional performance and scalability." Merv interviews two Exadata customers, Banco Transylvania and TUI Netherlands, and concludes that early indications are that Oracle Exadata is delivering on its promise of extreme performance and scalability. His recommendation to IT is to target corporate applications with the biggest potential for speed-based enhancement, and consider whether Oracle Exadata V2 can cost-effectively enable new ways to use these for competitive advantage.

• Why Wouldn't Root Be Able to Change a Zone's IP Address in Oracle Solaris 11?

  - by rickramsey

  You might assume that if you have root access to an Oracle Solaris zone, you'd be able to change the root's IP address. If so, you'd proceed along these lines ... First, you'd log in: root@global_zone:~# zlogin user-zone Then you'd remove the IP interface: root@user-zone:~# ipadm delete-ip vnic0 Next, you'd create a new IP interface: root@user-zone:~# ipadm create-ip vnic0 Then you'd assign the IP interface a new IP address (10.0.0.10): root@user-zone:~# ipadm create-addr -a local=10.0.0.10/24 vnic0/v4 ipadm: cannot create address: Permission denied Why would that happen? Here are some potential reasons: You're in the wrong zone Nobody bothered to tell you that you were fired last week. The sysadmin for the global zone (probably your ex-girlfriend) enabled link protection mode on the zone with this sweet little command: root@global_zone:~# dladm set-linkprop -p \ protection=mac-nospoof,restricted,ip-nospoof vnic0 How'd your ex-girlfriend learn to do that? By reading this article: Securing a Cloud-Based Data Center with Oracle Solaris 11 by Orgad Kimchi, Ron Larson, and Richard Friedman When you build a private cloud, you need to protect sensitive data not only while it's in storage, but also during transmission between servers and clients, and when it's being used by an application. When a project is completed, the cloud must securely delete sensitive data and make sure the original data is kept secure. These are just some of the many security precautions a sysadmin needs to take to secure data in a cloud infrastructure. Orgad, Ron, and Richard and explain the rest and show you how to employ the security features in Oracle Solaris 11 to protect your cloud infrastructure.

• What is a technique for 2D ray-box intersection that is suitable for old console hardware?

  - by DJCouchyCouch

  I'm working on a Sega Genesis homebrew game (it has a 7mhz 68000 CPU). I'm looking for a way to find the intersection between a particle sprite and a background tile. Particles are represented as a point with a movement vector. Background tiles are 8 x 8 pixels, with an (X,Y) position that is always located at a multiple of 8. So, really, I need to find the intersection point for a ray-box collision; I need to find out where along the edge of the tile the ray/particle hits. I have these two hard constraints: I'm working with pixel locations (integers). Floating point is too expensive. It doesn't have to be super exact, just close enough. Multiplications, divisions, dot products, et cetera, are incredibly expensive and are to be avoided. So I'm looking for an efficient algorithm that would fit those constraints. Any ideas? I'm writing it in C, so that would work, but assembly should be good as well.

• Do we have enough time to build an electric car future?

  - by julien.groues

  A recent article from Greenbang has posed the question 'Do we have enough time to build an electric car future?'. The writer discusses that, although the future of transport might lie with electric cars, there is concern regarding whether we'll be able to build the market and infrastructure required to support them, before carbon and oil constraints create difficulties in powering the vehicles. Of course, the increasing use of Electric vehicles (EVs) is going to put excessive pressure on energy grids, as large volumes of electricity will need to be directed to charging points, which in turn must handle fluctuating demand at peak times. EVs are increasing in popularity as a sustainable method of transport to reduce carbon consumption, and electric utilities will have the opportunity, and the challenge, to quickly determine the best methods to fuel these vehicles and accommodate the associated increases in demand for energy. Critically, efficient software is required to provide diagnostic and predictive capabilities related to EV refuelling - for example, anticipated electricity flow will need to be addressed as the number of EVs on the road increases, and electricity will need to be directed to specific areas on-demand as vehicles attempt to recharge en-mass. But a smart grid infrastructure can meet these demands, intelligently. The implementation of a smart grid is not in the distant future, it is an achievable reality for utilities via simple installation of new software and technologies, which can be done incrementally for those facing existing legacy systems or concerned with upfront costs. The smart grid is integral to the monitoring and control of energy use as well as the future-proofing of the energy grid. A smart grid will be critical to meeting the electricity requirements of new EVs and will ensure their successful deployment by providing a reliable foundation for the data handling required to record and manage electricity distribution - from recording and assessing energy usage, to analysing data and sharing information with consumers via green billing. http://www.greenbang.com/do-we-have-enough-time-to-build-an-electric-car-future_14248.html
