It’s no secret that complex, large-scale projects need close management controls to ensure that they’re delivered on time and on budget. But now there’s growing evidence that failing to meet these goals can have far-reaching consequences, not only for the reputations and value of individual organizations but also for the tenure of their top executives. Government watchdogs forced one large contractor to suspend a multibillion-dollar defense program—and delay payment receipts—until a better management system was launched to more accurately track spending, project milestones, and other fundamental metrics. Significant delays in the opening of the £4.3 billion Terminal 5 at Heathrow Airport impaired an airline’s operations and contributed to a drop in its share prices. These real-world examples are noteworthy because of the huge financial risks they created. They’re also far from being isolated cases. Research by the Economist Intelligence Unit found that only 11 percent of companies claimed they delivered expected ROI on major capital projects 90 percent of the time or more. In addition, 12 percent of respondents said they achieved planned ROI less than half the time. According to Phil Thornton, lead consultant at the analyst firm Clarity Economics, the numbers demonstrate obvious challenges related to managing risks, accurately predicting ROI, and consistently delivering bottom-line growth for major capital investments “Portfolio management is a path to improve your organization’s competitive advantage. It helps make sure your organization is investing in the right things and not spending its time on things that are not delivering the intended results for the firm.” Read the full article here

Rip and Convert DVD’s to an ISO Image

- by Mysticgeek

If you own a lot of DVD’s, you might want to convert them to an ISO image for backup and easily playing them on your media center. Today we take a look at ripping your discs using DVDFab, then using ImgBurn to create an ISO image of the ripped DVD files. Rip DVD with DVDFab6 DVDFab will remove copy protection and rip the DVD files for free. Other components in the suite require you to purchase a license after the 30 day trial, but you’ll still be able to rip DVD’s after the trial. Install DVDFab by accepting the defaults (link below)…a system restart is required to complete the install process. The first time you run it, a welcome screen is displayed. If you don’t want to see it again check the box Do not show again, then Start DVDFab. Pop the DVD in your drive and click Next. Now select your region and check Do not show again, then OK. It will then open the DVD and begin to scan it. Under DVD to DVD you can select either Full Disc or Main Movie depending on what you want to rip. If you want to burn the DVD to a disc after it’s created select the Full Disc option. Now click the Start button to begin the ripping process. After the ripping process has completed, you’ll get a message telling you it’s waiting for you to put in a blank DVD. Since we aren’t burning the disc, just cancel the message. Click Finish and close out of DVDFab or just minimize it if you’re going to keep using it to rip another DVD. By default the temporary directory is in My Documents \ DVDFab \ Temp…however you can change it in settings. If you go to the Temp directory you’ll see the DVD files listed there… Convert Files to ISO with ImgBurn Now that we have the files ripped from the DVD, we need to convert them to an ISO image using ImgBurn (link below). Open it up and from the main menu click on Create image file from files/folders. Click on the folder icon to browse to the location of the ripped DVD files. Browse to the DVDFab temp directory and the VIDEO_TS folder for the source and click Ok. Then choose a destination directory, give the ISO a name, and click Save. In this case we ripped the Unbreakable DVD, so named it that. So now in ImgBurn you have the source being the ripped DVD files, and the destination for the ISO…then click the Build button. If you don’t create a volume label, ImgBurn is kind enough to create on for you. If everything looks correct, click Ok. Now wait while ImgBurn goes through the process of converting the ripped DVD files to an ISO image. The process has successfully completed. The ISO image of the DVD will be in the output directory you selected earlier. Now you can burn the ISO image to a blank DVD or store it on an external hard drive for safe keeping. When you’re done, you’ll probably want to go into the temp DVDFab folder and delete the VOB and other files in the Video_TS folder as they will take up a lot of space on your hard drive. Conclusion Although this method requires two programs to make an ISO out of a DVD, it’s extremely quick. When burning DVD’s of various lengths, it took less than 30 minutes to get the final ISO. Now, you’ll have your DVD movies backed up in case something were to happen to the discs and are no longer playable. If you use Windows Media Center to watch your movies, check out our article on how to automatically mount and view ISO files in Windows 7 Media Center. With DVDFab, you get a 30 day fully functional trial for all of its features. You’ll still be able rip DVD’s even after the 30 day trial has ended. The more we’ve been using DVDFab, the more impressed we are with its capabilities, so after the 30 day trial you should consider purchasing a license. We will have a full review of the of it to share with you soon.

How to mount a disk that supports Samba sharing (Using Disk Utility)

- by Luis Alvarado - The Wolverine

This might be a tricky question but here is the objective: Manage to mount a disk/partition automatically without (or at least trying to avoid): Editing any Samba configuration file Editing the fstab file and to make it a little bit harder, this needs to be done with the options for "Mount Options" in the Disk Utility: Note that if left as it is, every time a user mounts a partition/disk and then tries to share a folder in it, Windows users can see the share but can not access it, with a permission warning appearing. The point of all of this is to find the most user friendly (Oriented towards a GUI) way of enabling a partition to be mounted, accessed by the local user (Read, Write, Execute) and to also be able to, when needed, share a folder and have no problems reading/writing on it from another Ubuntu/Windows/Mac remote computer (Assuming both are in the same LAN network).

Databound Accordian Control

This sample shows how to bind data to an AJAX Accordian control, using the AJAX Control Toolkit. The first thing you will need to do, is to download it from the AJax.ASP.Net website. Then, once it's downloaded and installed, go to the Bin folder, where it's located, find the AjaxcontrolToolkit.dll and copy it to the Bin folder of your website. Once it's there, you're off to the races. Note the 'Register' statement at the top of the code here, and then, look at the different properties in the control itself. When databinding the Accordian control, you will use the HeaderTemplate and ContentTemplate tags, instead of the normal Header and Content pane tags. Add a little CSS for flavor (see the ContentCssClass property of the Accordian control, and the DIV class for the header), and we're good to go.

Sinha writes: “Bad or missing data makes application systems fail when they process order-level data. One of the key items in the supply-chain industry is the product (aka SKU). Therefore, it becomes the most important data element to tie up multiple merchandising processes including purchase order allocation, stock movement, shipping notifications, and inventory details… Bad data can cause huge operational failures and cost millions of dollars in terms of time, resources, and money to clean up and validate data across multiple participating systems. Yes bad data really is the monster, so what do we do about it? Close our eyes and hope it stays in the closet? We’ve tacked this problem for some years now at Oracle, and with our latest introduction of Oracle Enterprise Data Quality along with our integrated Oracle Master Data Management products provides a complete, best-in-class answer to the bad data monster. What’s unique about it? Oracle Enterprise Data Quality also combines powerful data profiling, cleansing, matching, and monitoring capabilities while offering unparalleled ease of use. What makes it unique is that it has dedicated capabilities to address the distinct challenges of both customer and product data quality – [different monsters have different needs of course!]. And the ability to profile data is just as important to identify and measure poor quality data and identify new rules and requirements. Included are semantic and pattern-based recognition to accurately parse and standardize data that is poorly structured. Finally all of the data quality components are integrated with Oracle Master Data Management, including Oracle Customer Hub and Oracle Product Hub, as well as Oracle Data Integrator Enterprise Edition and Oracle CRM. Want to learn more? On Tuesday Nov 15th, I invite you to listen to our webcast on Reduce ERP consolidation risks with Oracle Master Data Management I’ll be joined by our partner iGate Patni and be talking about one specific way to deal with the bad data monster specifically around ERP consolidation. Look forward to seeing you there!

It was full of useful nuggets of information, such as why they chose to use BDB JE, performance, and some tips & tricks at the end. At over 40 minutes, the video is quite long. Ryan is an entertaining speaker, so I suggest you watch all of it.

ASP.NET MVC 3 Hosting :: Deploying ASP.NET MVC 3 web application to server where ASP.NET MVC 3 is not installed

- by mbridge

You can built sample application on ASP.NET MVC 3 for deploying it to your hosting first. To try it out first put it to web server where ASP.NET MVC 3 installed. In this posting I will tell you what files you need and where you can find them. Here are the files you need to upload to get application running on server where ASP.NET MVC 3 is not installed. Also you can deploying ASP.NET MVC 3 web application to server where ASP.NET MVC 3 is not installed like this example: you can change reference to System.Web.Helpers.dll to be the local one so it is copied to bin folder of your application. First file in this list is my web application dll and you don’t need it to get ASP.NET MVC 3 running. All other files are located at the following folder: C:\Program Files\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\Assemblies\ If there are more files needed in some other scenarios then please leave me a comment here. And… don’t forget to convert the folder in IIS to application. While developing an application locally, this isn’t a problem. But when you are ready to deploy your application to a hosting provider, this might well be a problem if the hoster does not have the ASP.NET MVC assemblies installed in the GAC. Fortunately, ASP.NET MVC is still bin-deployable. If your hosting provider has ASP.NET 3.5 SP1 installed, then you’ll only need to include the MVC DLL. If your hosting provider is still on ASP.NET 3.5, then you’ll need to deploy all three. It turns out that it’s really easy to do so. Also, ASP.NET MVC runs in Medium Trust, so it should work with most hosting providers’ Medium Trust policies. It’s always possible that a hosting provider customizes their Medium Trust policy to be draconian. Deployment is easy when you know what to copy in archive for publishing your web site on ASP.NET MVC 3 or later versions. What I like to do is use the Publish feature of Visual Studio to publish to a local directory and then upload the files to my hosting provider. If your hosting provider supports FTP, you can often skip this intermediate step and publish directly to the FTP site. The first thing I do in preparation is to go to my MVC web application project and expand the References node in the project tree. Select the aforementioned three assemblies and in the Properties dialog, set Copy Local to True. Now just right click on your application and select Publish. This brings up the following Publish wizard Notice that in this example, I selected a local directory. When I hit Publish, all the files needed to deploy my app are available in the directory I chose, including the assemblies that were in the GAC.

Error java.lang.OutOfMemoryError: getNewTla using Oracle EPM products

- by Marc Schumacher

Running into a Java out of memory error, it is very common behaviour in the field that the Java heap size will be increased. While this might help to solve a heap space out of memory error, it might not help to fix an out of memory error for the Thread Local Area (TLA). Increasing the available heap space from 1 GB to 16 GB might not even help in this situation. The Thread Local Area (TLA) is part of the Java heap, but as the name already indicates, this memory area is local to a specific thread so there is no need to synchronize with other threads using this memory area. For optimization purposes the TLA size is configurable using the Java command line option “-XXtlasize”. Depending on the JRockit version and the available Java heap, the default values vary. Using Oracle EPM System (mainly 11.1.2.x) the following setting was tested successfully: -XXtlasize:min=8k,preferred=128k More information about the “-XXtlasize” parameter can be found in the JRockit documentation: http://docs.oracle.com/cd/E13150_01/jrockit_jvm/jrockit/jrdocs/refman/optionXX.html

Command line method to find disk usage of camera mounted using gvfs

- by Hamish Downer

When my camera was mounted on /media I could use the standard tools (df) to see the disk usage of the card in my camera. However now the camera is mounted using gvfs, and df seems to ignore it. I've also tried pydf and discus to no avail. The camera is definitely available through nautilus, and when I select the camera in nautlius, the status bar tells me the amount of disk free. I can also open the ~/.gvfs/ folder in nautilus and right click on the camera folder and get the disk usage in a graphical way. But that is no use for a script. Are there command line tools that are the equivalent of df for gvfs filesystems? Or even better, a way to make df report on gvfs filesystems?

How do you dive into large code bases?

- by miku

What tools and techniques do you use for exploring and learning an unknown code base? I am thinking of tools like grep, ctags, unit-tests, functional test, class-diagram generators, call graphs, code metrics like sloccount and so on. I'd be interested in your experiences, the helpers you used or wrote yourself and the size of the codebase, with which you worked with. I realize, that this is also a process (happening over time) and that learning can mean "can give a ten minute intro" to "can refactor and shrink this to 30% of the size". Let's leave that open for now.

Rhythmbox won't import or play flac files

- by Dan Drake

I have a new installation of 12.04 and I just copied over all my music to the ~/Music folder. Rhythmbox found all the mp3 and ogg files, but it refuses to import flac files. They simply do not appear in my music library. If I start Rhythmbox on the command line and try to import a folder that contains flac files, absolutely nothing happens. Nothing is imported; no error messages. I have all the dependencies for Rhythmbox installed, along with all the suggested and recommended packages. I can play a flac file with gst-launch-0.10 and gst-typefind-0.10 correctly identifies flac files as audo/x-flac. Why does Rhythmbox refuse to see flac files? What can I do to find out what is happening?

Customizing Flowcharts in Oracle Tutor

- by [email protected]

Today we're going to look at how you can customize the flowcharts within Oracle Tutor procedures, and how you can share those changes with other authors within your company. Here is an image of a flowchart within a Tutor procedure with the default size and color scheme. You may want to change the size of your flowcharts as your end-users might have larger screens or need larger fonts. To change the size and number of columns, navigate to Tutor Author Author Options Flowcharts. The default is to have 4 columns appear in each flowchart, but, if I change it to six, my end-users will see a denser flowchart. This might be too dense for my end-users, so I will change it to 5 columns, and I will also deselect the option to have separate task boxes. Now let's look at how to customize the colors. Within the Flowchart options dialog, there is a button labeled "Colors." This brings up a dialog box of every object on a Tutor flowchart, and I can modify the color of each object, as well as the text within the object. If I click on the background, the "page" object appears in the Item field, and now I can customize the color and the title text by selecting Select Fill Color and/or Select Text Color. A dialog box with color choices appears. If I select Define Custom Colors, I can make my selections even more precise. Each time I change the color of an object, it appears in the selection screen. When the flowchart customization is finished, I can save my changes by naming the scheme. Although the color scheme I have chosen is rather silly looking, perhaps I want others to give me their feedback and make changes as they wish. I can share the color scheme with them by copying the FCP.INI file in the Tutor\Author directory into the same directory on their systems. If the other users have color schemes that they do not want to lose, they can copy the relevant lines from the FCP.INI file into their file. If I flowchart my document with the new scheme, I can see how it looks within the document. Sometimes just one or two changes to the default scheme are enough to customize the flowchart to your company's color palette. I have seen customers who have only changed the Start object to green and the End object to red, and I've seen another customer who changed every object to some variant of black and orange. Experiment! And let us know how you have customized your flowcharts. Mary R. Keane Senior Development Director, Oracle Tutor

xsltproc killed, out of memory

- by David Parks

I'm trying to split up a 13GB xml file into small ~50MB xml files with this XSLT style sheet. But this process kills xsltproc after I see it taking up over 1.7GB of memory (that's the total on the system). Is there any way to deal with huge XML files with xsltproc? Can I change my style sheet? Or should I use a different processor?

The Template Method Design Pattern using C# .Net

- by nijhawan.saurabh

First of all I'll just put this pattern in context and describe its intent as in the GOF book: Template Method: Define the skeleton of an algorithm in an operation, deferring some steps to Subclasses. Template Method lets subclasses redefine certain steps of an algorithm without changing the Algorithm's Structure. Usage: When you are certain about the High Level steps involved in an Algorithm/Work flow you can use the Template Pattern which allows the Base Class to define the Sequence of the Steps but permits the Sub classes to alter the implementation of any/all steps. Example in the .Net framework: The most common example is the Asp.Net Page Life Cycle. The Page Life Cycle has a few methods which are called in a sequence but we have the liberty to modify the functionality of any of the methods by overriding them. Sample implementation of Template Method Pattern: Let's see the class diagram first: Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:8.0pt; mso-para-margin-left:0in; line-height:107%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-font-kerning:1.0pt; mso-ligatures:standard;} And here goes the code:EmailBase.cs 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 7 namespace TemplateMethod 8 { 9 public abstract class EmailBase 10 { 11 12 public bool SendEmail() 13 { 14 if (CheckEmailAddress() == true) // Method1 in the sequence 15 { 16 if (ValidateMessage() == true) // Method2 in the sequence 17 { 18 if (SendMail() == true) // Method3 in the sequence 19 { 20 return true; 21 } 22 else 23 { 24 return false; 25 } 26 27 } 28 else 29 { 30 return false; 31 } 32 33 } 34 else 35 { 36 return false; 37 38 } 39 40 41 } 42 43 protected abstract bool CheckEmailAddress(); 44 protected abstract bool ValidateMessage(); 45 protected abstract bool SendMail(); 46 47 48 } 49 } 50 EmailYahoo.cs 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 7 namespace TemplateMethod 8 { 9 public class EmailYahoo:EmailBase 10 { 11 12 protected override bool CheckEmailAddress() 13 { 14 Console.WriteLine("Checking Email Address : YahooEmail"); 15 return true; 16 } 17 protected override bool ValidateMessage() 18 { 19 Console.WriteLine("Validating Email Message : YahooEmail"); 20 return true; 21 } 22 23 24 protected override bool SendMail() 25 { 26 Console.WriteLine("Semding Email : YahooEmail"); 27 return true; 28 } 29 30 31 } 32 } 33 EmailGoogle.cs 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 7 namespace TemplateMethod 8 { 9 public class EmailGoogle:EmailBase 10 { 11 12 protected override bool CheckEmailAddress() 13 { 14 Console.WriteLine("Checking Email Address : GoogleEmail"); 15 return true; 16 } 17 protected override bool ValidateMessage() 18 { 19 Console.WriteLine("Validating Email Message : GoogleEmail"); 20 return true; 21 } 22 23 24 protected override bool SendMail() 25 { 26 Console.WriteLine("Semding Email : GoogleEmail"); 27 return true; 28 } 29 30 31 } 32 } 33 Program.cs 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 7 namespace TemplateMethod 8 { 9 class Program 10 { 11 static void Main(string[] args) 12 { 13 Console.WriteLine("Please choose an Email Account to send an Email:"); 14 Console.WriteLine("Choose 1 for Google"); 15 Console.WriteLine("Choose 2 for Yahoo"); 16 string choice = Console.ReadLine(); 17 18 if (choice == "1") 19 { 20 EmailBase email = new EmailGoogle(); // Rather than newing it up here, you may use a factory to do so. 21 email.SendEmail(); 22 23 } 24 if (choice == "2") 25 { 26 EmailBase email = new EmailYahoo(); // Rather than newing it up here, you may use a factory to do so. 27 email.SendEmail(); 28 } 29 } 30 } 31 } 32 Final Words: It's very obvious that why the Template Method Pattern is a popular pattern, everything at last revolves around Algorithms and if you are clear with the steps involved it makes real sense to delegate the duty of implementing the step's functionality to the sub classes.

Hiding php includes from search spiders?

- by 21stcn

Quick and simple question. I have 80+ html files which I want to be crawled. They are individual product pages. Each of these pages calls its content using php includes. These php include files are in a separate folder on the server and contain the core content for the individual product pages. I just wanted to ask, if I use robots.txt or .htaccess to prevent crawling of the directory that holds the php content files, will there be no issue crawling the html pages which include these files? What I want to achieve is have the html files indexed with the php content included in them, but I don't want visitors landing on the php content pages, nor have these php files indexed as duplicate content. Just clarification needed as to whether it is safe to block spiders from accessing the php folder, without this affecting the html files being indexed with the included content. Is this the best way to do things? Or should I just leave the content php files to be crawled?

Backup all home folders on usb disk and accessibility

- by PatrickV

I am using Ubuntu 12.04 and have multiple family members working on it with there own home folder. I have an USB disk and want to use it to backup my home folders. Trying this, I got some questions. When my disk auto mount, it is not visible for each user. It seams to be visible for the user the time I connect the usb disk. I want to create one folder per home on the usb disk to backup the data to. But when I format the disk in EXT4 or FAT for example it is Read Only. How can I format the disk so it is accessible to every user. Best Regards, Patrick

Running a Mongo Replica Set on Azure VM Roles

- by Elton Stoneman

Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2013/10/15/running-a-mongo-replica-set-on-azure-vm-roles.aspxSetting up a MongoDB Replica Set with a bunch of Azure VMs is straightforward stuff. Here’s a step-by-step which gets you from 0 to fully-redundant 3-node document database in about 30 minutes (most of which will be spent waiting for VMs to fire up). First, create yourself 3 VM roles, which is the minimum number of nodes you need for high availability. You can use any OS that Mongo supports. This guide uses Windows but the only difference will be the mechanism for starting the Mongo service when the VM starts (Windows Service, daemon etc.) While the VMs are provisioning, download and install Mongo locally, so you can set up the replica set with the Mongo shell. We’ll create our replica set from scratch, doing one machine at a time (if you have a single node you want to upgrade to a replica set, it’s the same from step 3 onwards): 1. Setup Mongo Log into the first node, download mongo and unzip it to C:. Rename the folder to remove the version – so you have c:\MongoDB\bin etc. – and create a new folder for the logs, c:\MongoDB\logs. 2. Setup your data disk When you initialize a node in a replica set, Mongo pre-allocates a whole chunk of storage to use for data replication. It will use up to 5% of your data disk, so if you use a Windows VM image with a defsault 120Gb disk and host your data on C:, then Mongo will allocate 6Gb for replication. And that takes a while. Instead you can create yourself a new partition by shrinking down the C: drive in Computer Management, by say 10Gb, and then creating a new logical disk for your data from that spare 10Gb, which will be allocated as E:. Create a new folder, e:\data. 3. Start Mongo When that’s done, start a command line, point to the mongo binaries folder, install Mongo as a Windows Service, running in replica set mode, and start the service: cd c:\mongodb\bin mongod -logpath c:\mongodb\logs\mongod.log -dbpath e:\data -replSet TheReplicaSet –install net start mongodb 4. Open the ports Mongo uses port 27017 by default, so you need to allow access in the machine and in Azure. In the VM, open Windows Firewall and create a new inbound rule to allow access via port 27017. Then in the Azure Management Console for the VM role, under the Configure tab add a new rule, again to allow port 27017. 5. Initialise the replica set Start up your local mongo shell, connecting to your Azure VM, and initiate the replica set: c:\mongodb\bin\mongo sc-xyz-db1.cloudapp.net rs.initiate() This is the bit where the new node (at this point the only node) allocates its replication files, so if your data disk is large, this can take a long time (if you’re using the default C: drive with 120Gb, it may take so long that rs.initiate() never responds. If you’re sat waiting more than 20 minutes, start another instance of the mongo shell pointing to the same machine to check on it). Run rs.conf() and you should see one node configured. 6. Fix the host name for the primary – *don’t miss this one* For the first node in the replica set, Mongo on Windows doesn’t populate the full machine name. Run rs.conf() and the name of the primary is sc-xyz-db1, which isn’t accessible to the outside world. The replica set configuration needs the full DNS name of every node, so you need to manually rename it in your shell, which you can do like this: cfg = rs.conf() cfg.members[0].host = ‘sc-xyz-db1.cloudapp.net:27017’ rs.reconfig(cfg) When that returns, rs.conf() will have your full DNS name for the primary, and the other nodes will be able to connect. At this point you have a working database, so you can start adding documents, but there’s no replication yet. 7. Add more nodes For the next two VMs, follow steps 1 through to 4, which will give you a working Mongo database on each node, which you can add to the replica set from the shell with rs.add(), using the full DNS name of the new node and the port you’re using: rs.add(‘sc-xyz-db2.cloudapp.net:27017’) Run rs.status() and you’ll see your new node in STARTUP2 state, which means its initializing and replicating from the PRIMARY. Repeat for your third node: rs.add(‘sc-xyz-db3.cloudapp.net:27017’) When all nodes are finished initializing, you will have a PRIMARY and two SECONDARY nodes showing in rs.status(). Now you have high availability, so you can happily stop db1, and one of the other nodes will become the PRIMARY with no loss of data or service. Note – the process for AWS EC2 is exactly the same, but with one important difference. On the Azure Windows Server 2012 base image, the MongoDB release for 64-bit 2008R2+ works fine, but on the base 2012 AMI that release keeps failing with a UAC permission error. The standard 64-bit release is fine, but it lacks some optimizations that are in the 2008R2+ version.

Where can I ask web design questions of a more amateur nature?

- by Warren van Rooyen

I don't want to bother pro web designers with simple questions as I see most of the questions here are quite technical. An example would be, 'I have a template I've downloaded. The folder contains a css folder and PHP files. How would I bring this into Dreamweaver?' It's unfortunately in a space between what I'd be able to find on Google and asking here without feeling like a hinderance for those who don't want to answer such simple questions. Thanks, Warren.

does eCryptfs support multiple users?

- by new to eCryptfs

I'm new to ecryptfs and I need some clarification on how it works. Suppose there are two root users userA and userB, If I mount some folder under userA: [userA@Dev] $ mount ecryptfs real img now I can visit the img folder to access decrypted data. My questions is: While userA is still in log in state. Can userB login and access the decrypted data? This is currently what I observed on my local machine, but I'm not sure if it was cause by my misconfiguration. If it is the case, how can I avoid other users from accessing the decrypted data while userA is in login state?

Commandline shortcut for current directory similar to ~ for home directory?

- by NES

When i use the cp or move command in a terminal window, i'm currently with bash in a certain folder like this. NES@server:~/Desktop/dir1$ And now i wanna copy a file from here ~/anotherdir/dir2 into the current chosen folder in bash (dir1) i would use the command cp ~/anotherdir/dir2/file ~/Desktop/dir1 does a shortcut string exist to refer to the current chosen directory? So that in this example i don't have to provide the full path to the target dir, but the command knows it should use the current chosen directory in bash? i.e. as ~ stands for the home directory?

How to structure game states in an entity/component-based system

- by Eva

I'm making a game designed with the entity-component paradigm that uses systems to communicate between components as explained here. I've reached the point in my development that I need to add game states (such as paused, playing, level start, round start, game over, etc.), but I'm not sure how to do it with my framework. I've looked at this code example on game states which everyone seems to reference, but I don't think it fits with my framework. It seems to have each state handling its own drawing and updating. My framework has a SystemManager that handles all the updating using systems. For example, here's my RenderingSystem class: public class RenderingSystem extends GameSystem { private GameView gameView_; /** * Constructor * Creates a new RenderingSystem. * @param gameManager The game manager. Used to get the game components. */ public RenderingSystem(GameManager gameManager) { super(gameManager); } /** * Method: registerGameView * Registers gameView into the RenderingSystem. * @param gameView The game view registered. */ public void registerGameView(GameView gameView) { gameView_ = gameView; } /** * Method: triggerRender * Adds a repaint call to the event queue for the dirty rectangle. */ public void triggerRender() { Rectangle dirtyRect = new Rectangle(); for (GameObject object : getRenderableObjects()) { GraphicsComponent graphicsComponent = object.getComponent(GraphicsComponent.class); dirtyRect.add(graphicsComponent.getDirtyRect()); } gameView_.repaint(dirtyRect); } /** * Method: renderGameView * Renders the game objects onto the game view. * @param g The graphics object that draws the game objects. */ public void renderGameView(Graphics g) { for (GameObject object : getRenderableObjects()) { GraphicsComponent graphicsComponent = object.getComponent(GraphicsComponent.class); if (!graphicsComponent.isVisible()) continue; GraphicsComponent.Shape shape = graphicsComponent.getShape(); BoundsComponent boundsComponent = object.getComponent(BoundsComponent.class); Rectangle bounds = boundsComponent.getBounds(); g.setColor(graphicsComponent.getColor()); if (shape == GraphicsComponent.Shape.RECTANGULAR) { g.fill3DRect(bounds.x, bounds.y, bounds.width, bounds.height, true); } else if (shape == GraphicsComponent.Shape.CIRCULAR) { g.fillOval(bounds.x, bounds.y, bounds.width, bounds.height); } } } /** * Method: getRenderableObjects * @return The renderable game objects. */ private HashSet<GameObject> getRenderableObjects() { return gameManager.getGameObjectManager().getRelevantObjects( getClass()); } } Also all the updating in my game is event-driven. I don't have a loop like theirs that simply updates everything at the same time. I like my framework because it makes it easy to add new GameObjects, but doesn't have the problems some component-based designs encounter when communicating between components. I would hate to chuck it just to get pause to work. Is there a way I can add game states to my game without removing the entity-component design? Does the game state example actually fit my framework, and I'm just missing something? EDIT: I might not have explained my framework well enough. My components are just data. If I was coding in C++, they'd probably be structs. Here's an example of one: public class BoundsComponent implements GameComponent { /** * The position of the game object. */ private Point pos_; /** * The size of the game object. */ private Dimension size_; /** * Constructor * Creates a new BoundsComponent for a game object with initial position * initialPos and initial size initialSize. The position and size combine * to make up the bounds. * @param initialPos The initial position of the game object. * @param initialSize The initial size of the game object. */ public BoundsComponent(Point initialPos, Dimension initialSize) { pos_ = initialPos; size_ = initialSize; } /** * Method: getBounds * @return The bounds of the game object. */ public Rectangle getBounds() { return new Rectangle(pos_, size_); } /** * Method: setPos * Sets the position of the game object to newPos. * @param newPos The value to which the position of the game object is * set. */ public void setPos(Point newPos) { pos_ = newPos; } } My components do not communicate with each other. Systems handle inter-component communication. My systems also do not communicate with each other. They have separate functionality and can easily be kept separate. The MovementSystem doesn't need to know what the RenderingSystem is rendering to move the game objects correctly; it just need to set the right values on the components, so that when the RenderingSystem renders the game objects, it has accurate data. The game state could not be a system, because it needs to interact with the systems rather than the components. It's not setting data; it's determining which functions need to be called. A GameStateComponent wouldn't make sense because all the game objects share one game state. Components are what make up objects and each one is different for each different object. For example, the game objects cannot have the same bounds. They can have overlapping bounds, but if they share a BoundsComponent, they're really the same object. Hopefully, this explanation makes my framework less confusing.
