  • DB Documentation Tool

    - by Hisham El-bereky
     Recently I have uploaded new project to codeplex site, DbDocument or DbDoc project is a helper tool used side by side with MS SQL server management studio tool, you can design your DB Tables in visualized way through Diagrams and then use “DbDoc” tool to generate design document in MS Word format, the generated file can be used in design review process or as history reference, the tool facilitate and reduce the time of writing DB structure documentthe current version is not so sophisticated which is intend to generate word document in table format with all tables in DB illustrating its structure and constraints, but for now it seems to be good.   For more details check DbDoc document or go immediately to DbDoc home page http://dbdocument.codeplex.com/

  • Using Hadooop (HDInsight) with Microsoft - Two (OK, Three) Options

    - by BuckWoody
    Microsoft has many tools for “Big Data”. In fact, you need many tools – there’s no product called “Big Data Solution” in a shrink-wrapped box – if you find one, you probably shouldn’t buy it. It’s tempting to want a single tool that handles everything in a problem domain, but with large, complex data, that isn’t a reality. You’ll mix and match several systems, open and closed source, to solve a given problem. But there are tools that help with handling data at large, complex scales. Normally the best way to do this is to break up the data into parts, and then put the calculation engines for that chunk of data right on the node where the data is stored. These systems are in a family called “Distributed File and Compute”. Microsoft has a couple of these, including the High Performance Computing edition of Windows Server. Recently we partnered with Hortonworks to bring the Apache Foundation’s release of Hadoop to Windows. And as it turns out, there are actually two (technically three) ways you can use it. (There’s a more detailed set of information here: http://www.microsoft.com/sqlserver/en/us/solutions-technologies/business-intelligence/big-data.aspx, I’ll cover the options at a general level below)  First Option: Windows Azure HDInsight Service  Your first option is that you can simply log on to a Hadoop control node and begin to run Pig or Hive statements against data that you have stored in Windows Azure. There’s nothing to set up (although you can configure things where needed), and you can send the commands, get the output of the job(s), and stop using the service when you are done – and repeat the process later if you wish. (There are also connectors to run jobs from Microsoft Excel, but that’s another post)   This option is useful when you have a periodic burst of work for a Hadoop workload, or the data collection has been happening into Windows Azure storage anyway. That might be from a web application, the logs from a web application, telemetrics (remote sensor input), and other modes of constant collection.   You can read more about this option here:  http://blogs.msdn.com/b/windowsazure/archive/2012/10/24/getting-started-with-windows-azure-hdinsight-service.aspx Second Option: Microsoft HDInsight Server Your second option is to use the Hadoop Distribution for on-premises Windows called Microsoft HDInsight Server. You set up the Name Node(s), Job Tracker(s), and Data Node(s), among other components, and you have control over the entire ecostructure.   This option is useful if you want to  have complete control over the system, leave it running all the time, or you have a huge quantity of data that you have to bulk-load constantly – something that isn’t going to be practical with a network transfer or disk-mailing scheme. You can read more about this option here: http://www.microsoft.com/sqlserver/en/us/solutions-technologies/business-intelligence/big-data.aspx Third Option (unsupported): Installation on Windows Azure Virtual Machines  Although unsupported, you could simply use a Windows Azure Virtual Machine (we support both Windows and Linux servers) and install Hadoop yourself – it’s open-source, so there’s nothing preventing you from doing that.   Aside from being unsupported, there are other issues you’ll run into with this approach – primarily involving performance and the amount of configuration you’ll need to do to access the data nodes properly. But for a single-node installation (where all components run on one system) such as learning, demos, training and the like, this isn’t a bad option. Did I mention that’s unsupported? :) You can learn more about Windows Azure Virtual Machines here: http://www.windowsazure.com/en-us/home/scenarios/virtual-machines/ And more about Hadoop and the installation/configuration (on Linux) here: http://en.wikipedia.org/wiki/Apache_Hadoop And more about the HDInsight installation here: http://www.microsoft.com/web/gallery/install.aspx?appid=HDINSIGHT-PREVIEW Choosing the right option Since you have two or three routes you can go, the best thing to do is evaluate the need you have, and place the workload where it makes the most sense.  My suggestion is to install the HDInsight Server locally on a test system, and play around with it. Read up on the best ways to use Hadoop for a given workload, understand the parts, write a little Pig and Hive, and get your feet wet. Then sign up for a test account on HDInsight Service, and see how that leverages what you know. If you're a true tinkerer, go ahead and try the VM route as well. Oh - there’s another great reference on the Windows Azure HDInsight that just came out, here: http://blogs.msdn.com/b/brunoterkaly/archive/2012/11/16/hadoop-on-azure-introduction.aspx

    what is wrong with this easy script? I just want to write an script which change my directory: A. I put below commands on the file witch its name is pathABC on the /home/alex directory, #!/bin/sh cd /home/alex/Documents/A/B/C echo HelloWorld B. also I did chmod +x pathABC , On the terminal when I am on the /home/alex directory, I run ./pathABC . But the output is just HelloWorld and the current directory remains with no change. I mean my directory remains as /home/alex and not go to the /home/alex/Documents/A/B/C. So where is wrong?

  • Will LAMP meet the following needs?

    - by Telis Duvoir
    I remember a few years back, when I had a web-site I wanted to develop, that many people recommended I go the LAMP route. Unfortunately, I never got around to studying/practicing that. I'm currently revisiting the web-site idea. The web-site will be dynamic, transactional, and hopefully end up with around 1,000,000 pv/mo and 300,000 members within 18 months. Will LAMP adequately support a site like that (i.e. have you seen it under a site with those specs)?

  • Running 32-bit SSIS in a 64-bit Environment

    - by John Paul Cook
    After my recent post on where to find the 32-bit ODBC Administrator on a 64-bit SQL Server, a new question was asked about how to get SSIS to run with the 32-bit ODBC instead of the 64-bit ODBC. You need to make a simple configuration change to the properties of your BIDS solution. Here I have a solution called 32bitODBC and it needs to run in 32-bit mode, not 64-bit mode. Since I have a 64-bit SQL Server, BIDS defaults to using the 64-bit runtime. To override this setting, go to the property pages...(read more)

  • Dual Monitor results in 'greyed' windows

    - by paula
    This occurs in Maverick and Natty. Single screen is fine, mirror of single screen is fine. If the mirror box is unchecked and the second monitor is turned on to extend the desktop then all windows are greyed out (like they do when a process has timed out and is unresponsive) and pop up menus are greyed out but icons, panels and background are fine and the windows do operate (just can't see them well enough to use) I have a D620 with intel graphics. This machine did work with dual monitors at some time in the past, however I have been using another machine, a D630 with nvidia and it works fine. Yes, there have been any number of updates. I also upgraded from Maverick to Natty to see if it would go away. No joy. Also, the D620 has a dual boot windows system and the windows xp system works fine with daul monitors There is a forum thread that goes into more detail and there are a number of users experiencing this problem. Thread: greyed out windows Thanks for reading paula_ke

  • Font rendering in Firefox is blurry

    - by Mehrdad
    A picture is worth a thousand words... so does anyone know how to fix this font blurriness in Firefox? (You'll need to right-click the picture below go to View Image to view it full-size; it's too small to see anything here.) Note: My other applications (and the Firefox non-client area, as you can see in the screen) are completely fine, so obviously going to System-Appearance and changing the font settings isn't fixing the situation. Edit: Not letting web pages to use their own fonts also doesn't help: See how the upper one is still sharper? Also, Firefox's own menu bar doesn't render the same way as the page content (menu bar below, page content above). They're both Segoe UI:

  • Can you install ubuntu on xp and then uninstall xp? how?

    - by Eli
    I have a problem with my pc, you can read about it here if you like http://yhoo.it/qIQyMw anyway, I might go for ubuntu, the thing is I'm in Lebanon and here few, very few people use linux, most of them never heard about ubuntu lol, therefore you'll be really lucky if you can buy an ubuntu cd or even if you find someone can find someone capable of installing it. So when they fix my pc, they might install xp coz they don't have a linux operating system, and i hate win 7 and vista so I'll have to download ubuntu and install it by myself, I don't want to dual boot coz i don't have a super computer lol, i have used ubuntu on my vps, never on desktop before so i would like to know if you can download ubuntu, install it, on a xp pro, then remove xp pro? is there any tutorial? thank you

  • gnome-shell failed to launch when dual monitor detected, nvidia card

    - by Terry Hu
    I installed a clean precise. I like gnome-shell so I installed it. It worked well with single monitor. But It does not work well when I go to office, plug my external monitor onto my laptop. I am using nvidia driver. Another colleague is using the same laptop, he can work well with dual monitors. His laptop is ATI graphic card. When I plug my extended monitor cable, I choose GNOME, but actually it goes to gnome 2 classic desktop environment, not GNOME 3. When I disconnect the extended monitor, restart X, I can login with GNOME3. Do I have to choose between GNOME3 and extended monitor? It's a hard choose.

  • File Transfer using RDP

    - by DesigningCode
    I often use RDP to log into servers.   A couple of issues I have had is that its a pain to get files onto the server from my PC at times, and, if there is something missing from the servers windows install, I can’t simply pop the DVD into remote server in some unknown location on the internet somewhere. The other day I was curious if RDP actually had anything…since it did support shared clipboards, so I went for a look through the options and low and behold, *hidden* away….. Select Options… Go to the “Local Resources” Tab, then where it has “Local devices and resources” it sneakily has a “More…” button. Which then displays a drive selection box.  Select the drive you want …. Then on your server you will get….. Nice.  That is useful.

  • How do people get around the Carmack's Reverse patent?

    - by Rei Miyasaka
    Apparently, Creative has a patent on Carmack's Reverse, and they successfully forced Id to modify their techniques for the source drop, as well as to include EAX in Doom 3. But Carmack's Reverse is discussed quite often and apparently it's a good choice for deferred shading, so it's presumably used in a lot of other high-budget productions too. Even though it's unlikely that Creative would go after smaller companies, I'm wondering how the bigger studios get around this problem. Do they just cross their fingers and hope Creative doesn't troll them, or do they just not use Carmack's Reverse at all?

  • Factors to consider when building an algorithm for gun recoil

    - by Nate Bross
    What would be a good algorithm for calculating the recoil of a shooting guns cross-hairs? What I've got now, is something like this: Define min/max recoil based on weapon size Generate random number of "delta" movement Apply random value to X, Y, or both of cross-hairs (only "up" on the Y axis) Multiply new delta based on time from the previous shot (more recoil for full-auto) What I'm worried about is that this feels rather predicable, what other factors should one take into account when building recoil? While I'd like it to be somewhat predictable, I'd also like to keep players on their toes. I'm thinking about increasing the min/max recoil values by a large amount (relatively) and adding a weighting, so large recoils will be more rare -- it seems like a lot of effort to go into something I felt would be simple. Maybe this is just something that needs to be fine-tuned with additional playtesting, and more playtesters? I think that it's important to note, that the recoil will be a large part of the game, and is a key factor in the game being fun/challenging or not.

  • Project migration tips [closed]

    - by Shirish11
    I would like to know what all things are to be considered when your client asks for Project Migration to a different language / version. Migrating an existing project to a higher version is not going to be much of a trouble. Have to take care of some system files, some settings changes and if version specific components included then search for them to comply with the newer version. I understand why you need to migrate projects to newer versions mostly for overcoming the drawbacks of current version. But I have absolutely no idea how to go about language migration. Any help on this is appreciated . Moreover is language migration a healthy idea?

  • Display root node of Hierarchical Tree using ADF - EJB DC

    - by arul.wilson(at)oracle.com
    Displaying Employee (HR schema) records in Hierarchical Tree can be achieved in ADF-BC by creating custom VO and a Viewlink for displaying root node. This can be more easily done using  EJB-DC by just introducing a NamedQuery to get the root node.Here you go to get this scenario working.Create DB connection based on HR schema.Create Entity Bean from Employees Table.Add custom NamedQuery to Employees.java bean, this named query is responsible for fetching the root node (King in this example). @NamedQueries({  @NamedQuery(name = "Employees.findAll", query = "select o from Employees o"),  @NamedQuery(name = "Employees.findRootEmp", query = "select p from Employees p where p.employees is null")}) Create Stateless Session Bean and expose the Named Queries through the Session Facade.Create Datacontrol from SessionBean local interface.Create jspx page in ViewController project.Drop employeesFindRootEmp from Data Controls Palette as ADF Tree.Add employeesList as Tree level rule.Run page to see the hierarchical tree with root node as 'King'

  • SOA Suite 11g Dynamic Payload Testing with soapUI Free Edition

    - by Greg Mally
    Overview Many web service developers use soapUI for various tests like: smoke test, unit test, and load testing because you can get a free edition that is fairly robust. However, if you need to venture into more complex testing that requires a dynamic payload, then the free edition doesn't necessarily make it easy. This feature does exist in soapUI, but for obvious reasons it is in the Pro version. In this blog I will show you how to use soapUI free edition for dynamic payloads in a simplified example. Hopefully this will open the doors for you to expand into more complex scenarios. The following assumes that you have a working knowledge of soapUI and will not go into concepts like setting up a project etc. For the basics, please review the documentation for soapUI: http://www.soapui.org/Getting-Started/. Additionally, we will be using asynchronous web services and you can review the setup for this in my blog: SOA Suite 11g Asynchronous Testing with soapUI. Features in soapUI Free Edition Relating to this Topic The soapUI test tool provides a very feature rich environment that can do many things provided you are willing to go beyond point and click. For this example, we will be leveraging just a couple features for our dynamic payload example: Test Case Properties Scripting with Groovy Basically, we will be using a property as a global variable and we will manipulate that property using a Groovy script. Setting Up Our Property Properties are available throughout soapUI and here is a snippet from the soapUI website defining the locations: Projects : for handling Project scope values, for example a subscription ID TestSuite : for handling TestSuite scoped values, can be seen as "arguments" to a TestSuite TestCases : for handling TestCase scoped values, can be seen as "arguments" to a TestCase Properties TestStep : for providing local values/state within a TestCase Local TestStep properties : several TestStep types maintain their own list of properties specific to their functionality : DataSource, DataSink, Run TestCase MockServices : for handling MockService scoped values/arguments MockResponses : for handling MockResponse scoped values Global Properties : for handling Global properties, optionally from an external source For our example, we will be defining a custom property in a TestCase called SimpleAsyncPayload. The property can be created in either the Custom Properties tab located at the bottom of the Navigator panel when the TestCase is selected in the Navigator or the Properties label in the TestCase editor: Navigator Panel TestCase Editor You will notice that I set a value of “0” for the custom property. For this simplified example, we will need to retrieve that value and manipulate it prior to making the web service request invocation. In order to accomplish this, we will need to get Groovy ;) Let's Get Groovy We will now add a new Groovy Script step to the TestCase called Manipulate Payload: TestCase Editor > Append Step > Groovy Script Once we have added the Groovy Script step to our TestCase, we can open the Groovy Script editor to add the code to: Get the current value of the property we created called SimpleAsyncPayload. Convert the value of the property to an integer. Increment the value. Store the incremented value back into the TestCase property called SimpleAsyncPayload. The script should look something like the following: Groovy Script Editor – Manipulate Payload At this point we can test the script to see if it is working by simply running the TestCase (left-click on the green triangle in the upper left-hand corner of the TestCase editor). To verify if it ran correctly, we can look at the value of the SimpleAsyncPayload property which should now be 1: TestCase Editor – Run Results All that is left to complete the TestCase is to append another step of type Test Request. The information required to append the request is a name and an operation to invoke. In this example we will use the default name and select the SimpleAsyncBPELProcessBingd -> process as the operation (any other information being requested, simply use the defaults unless you are calling an asynchronous operation then do not add any assertions). We are now in familiar ground with the Test Request editor. Depending upon the type of operation you are invoking (synchronous or asynchronous), please update the request with the necessary information (e.g., callback information for asynchronous operations). We will now tweak the Test Request payload to retrieve the value of the SimpleAsyncPayload property. The soapUI editor makes this very simple: right-click in the payload and navigate to the property (e.g., right-click > Get Data.. > TestCase: [Groovy TestCase] > Property [SimpleAsyncPayload]): Test Request Editor – Insert Property Value Your payload should now look something like the following: Test Request Editor – Inserted Property Value Just like before, we are now ready to run the TestCase. If everything goes as expected we should see a response like the following: Message Viewer – Results of TestCase Run We are now setup to be able to run a stress test where the payload will change for each request. This simple example can be expanded to include multiple payload values, complex calculations in the scripts, or whatever can be done via the soapUI scripting. Hopefully you have found this useful and happy testing to you :)

    I have a strange problem. When I copy/paste via ethernet everything is working fine. But when I go to youtube or downloading some files via internet, connection is freezing very often.

  • Website Access...DNS, ISP, issue?

    - by sublet
    This isn't so much a code issue as it might be an issue with my ISP. For some reason when I visit a site very often, like one I manage or write stories on, it will just stop pulling data down after a while. It's very random when it happens, but probably happens once a week. If effects everyone who is accessing the site from this connection, and I can access other sites no problem. Also, if I go outside the office back home, which is right down the street, and access the site it is fine. I'm using Comcast in both locations. It's almost as if I have a limit on requests to each site and have hit my limit so it blocks the site for a while. Anybody have any clue what this might be?

  • The standards that fail us and the intellectual bubble

    - by Jeff
    There has been a great deal of noise in the techie community about standards, and a sudden and unexplainable hate for Flash. This noise isn't coming from consumers... the countless soccer moms, teens and your weird uncle Bob, it's coming from the people who build (or at least claim to build) the stuff those consumers consume. If you could survey the position of consumers on the topic, they'd likely tell you that they just want stuff on the Web to work.The noise goes something like this: Web standards are the correct and right thing to use across the Intertubes, and anything not a part of those standards (Flash) is bad. Furthermore, the more recent noise is centered around the idea that HTML 5, along with Javascript, is the right thing to use. The arguments against Flash are, well, the truth is I haven't seen a good argument. I see anecdotal nonsense about high CPU usage and things I'd never think to check when I'm watching Piano Cat on YouTube, but these aren't arguments to me. Sure, I've seen it crash a browser a few times, but it's totally rare.But let's go back to standards. Yes, standards have played an important role in establishing the ubiquity of the Web. The protocols themselves, TCP/IP and HTTP, have been critical. HTML, which has served us well for a very long time, established an incredible foundation. Javascript did an OK job, and thanks to clever programmers writing great frameworks like JQuery, is becoming more and more useful. CSS is awful (there, I said it, I feel SO much better), and I'll never understand why it's so disconnected and different from anything else. It doesn't help that it's so widely misinterpreted by different browsers. Still, there's no question that standards are a good thing, and they've been good for the Web, consumers and publishers alike.HTML 4 has been with us for more than a decade. In Web years, that might as well be 80. HTML 5, contrary to popular belief, is not a standard, and likely won't be for many years to come. In fact, the Web hasn't really evolved at all in terms of its standards. The tools that generate the standard markup and script have, but at the end of the day, we're still living with standards that are more than ten years old. The "official" standards process has failed us.The Web evolved anyway, and did not wait for standards bodies to decide what to do next. It evolved in part because Macromedia, then Adobe, kept evolving Flash. In the earlier days, it mostly just did obnoxious splash pages, but then it started doing animation, and then rich apps as they added form input. Eventually it found its killer app: video. Now more than 95% of browsers have Flash installed. Consumers are better for it.But I'll do it one better... I'll go out on a limb and say that Flash is a standard. If it's that pervasive, I don't care what you tell me, it's a standard. Just because a company owns it doesn't mean that it's evil or not a standard. And hey, it pains me to say that as a developer, because I think the dev tools are the suck (more on that in a minute). But again, consumers don't care. They don't even pay for Flash. The bottom line is that if I put something Flash based on the Internet, it's likely that my audience will see it.And what about the speed of standards owned by a company? Look no further than Silverlight. Silverlight 2 (which I consider the "real" start to the story) came out about a year and a half ago. Now version 4 is out, and it has come a very long way in its capabilities. If you believe Riastats.com, more than half of browsers have it now. It didn't have to wait for standards bodies and nerds drafting documents, it's out today. At this rate, Silverlight will be on version 6 or 7 by the time HTML 5 is a ratified standard.Back to the noise, one of the things that has continually disappointed me about this profession is the number of people who get stuck in an intellectual bubble, color it with dogmatic principles, and completely ignore the actual marketplace where this stuff all has to live. We aren't machines; Binary thinking that forces us to choose between "open standards" and "proprietary lock-in" (the most loaded b.s. FUD term evar) isn't smart at all. The truth is that the <object> tag has allowed us to build incredible stuff on top of the old standards, and consumers have benefitted greatly. Consumer desire, capitalism, and yes, standards ratified by nerds who think about this stuff for years have all played a role in the broad adoption of the Interwebs.We could all do without the noise. At the end of the day, I'm going to build stuff for the Web that's good for my users, and I'm not going to base my decisions on a techie bubble religion. Imagine what the brilliant minds behind the noise could do for the Web if they joined me in that pursuit.

  • What is the best way to learn how to develop secure applications

    - by Kenneth
    I would like to get into computer security in my career. What are the best ways to learn how to program securely? It seems to me that besides textbooks and taking classes in the subject that perhaps learning how to "hack" would be one of the best ways to learn. My reason for thinking this is the thought that the best way to learn how to prevent someone from doing what you don't want them to is to learn what they're capable of doing. If this is the case, then this poses another question: How would you go about learning to hack in an ethical manner? I definitely don't want to break laws or cause harm in my quest. Thanks for the input!

  • Gravity Forms not loading under https, jQuery is not defined

    - by cmykrgbb
    I am using Gravity Forms on my Wordpress site, and so far so good. The problem is I have made the page secure (https/SSL), and this is making the form not to work. It looks like the issue is how the site is trying to load jQuery. There are 23 JS errors on the page, which seem to be due to a failed jQuery load "Uncaught ReferenceError: jQuery is not defined". If I go to the page where the source is trying to pull the jQuery file, you'll see the error:https://code.jquery.com/jquery-1.7.1.min.js?ver=3.4.2 Screenshot of the error: https://www.evernote.com/shard/s212/sh/326f95d6-a498-4c33-b413-7e968225cc79/c2e380ed0fa02a913f712005c8301185 And this screenshot is the reference in the page source: https://www.evernote.com/shard/s212/sh/ae547962-c017-4321-90a2-c51433e59262/124ae116f2b803771f4eb36c90b5a524 So I have been told I'd want to look into that - that's where the ultimate issue is, but I don't really know what to do next. Is it failing because of Gravity Forms, the HTTPS plugin from Wordpress, my SSL certificate...? Thanks in advance!

  • External Video Hosting - will it eat my bandwidth?

    - by user4524
    I hav asked this question before, on serverfault, but have been unable to get a clear answer or spammy ones. A client runs a website with limited bandwidth per month (10gb) but wants his users to be able to download hq videos. Now if he would rent hosting space on amazon, for example, the downloads would still go through his website right? So would this then still eat his bandwidth then, or not? It there a way to circumvent this? How do you do this, if you have limited bandwidth? If you are kind enough to answer, please don't spam me with what is good and not good hosting, I already know.
