• Review: ComponentOne Studio for Entity Framework

  - by Tim Murphy

  While I have always been a fan of libraries that improve coding efficiency and reduce code redundancy I have mostly been using ones that were in the public domain.  As part of the Geeks With Blogs Influencers program a got my hands on ComponentOne’s Studio for Entity Framework.  Below are my thought after working with the product for several weeks. My coding preference has always been maintainable code that is reusable across an enterprises protfolio.  Because of this my focus in reviewing this product is less on the RAD components and more on its benefits for layered applications using code first Entity Framework. Before we get into the pros and cons here is a summary of the main feature listed for SEF. Unified Data Context Virtual Data Access More Powerful Data Binding Pros The first thing that I found to my liking is the C1DataSource. It basically manages a cache for your Entity Model context.  Under RAD conditions this is setup automatically when you drop the object on a your design surface.  If you are like me and want to abstract you data management into a library it takes a little more work, but it is still acceptable and gains the same benefits. The second feature that I found beneficial is the definition of views with improved sorting and filtering.  Again the ease of use of these features is greater on the RAD side but no capabilities are missing when manipulating object in code. Linq has become my friend over the last couple of years and it was great to see that ComponentOne had ensured that it remained a first class citizen in their design.  When you look into this product yourself I would suggest taking a dive into LiveLinq which allow the joining of different data source types. As I went through discovering the features of this framework I appreciated the number of examples that they supplied for different uses.  Besides showing how to use SEF with WinForms, WPF and Silverlight they also showed how to accomplish tasks both RAD, code only and MVVM approaches. Cons The only area that I would really like to see improvement is in there level of detail in their documentation.  Specifically I would like to have seen some of the supporting code explained, such as what some supporting object did, in the examples instead of having to go to the programmer’s reference. I did find some times where currently existing projects had some trouble determining scope that the RAD controls were allowed, but I expect this is something that is in part end user related. Summary Overall I found the Studio for Entity Framework capable and well thought out.  If you are already using the Entity Framework this product will fit into your environment with little effort in return for greater flexibility and greater robustness in your solutions. Whether the $895 list price for a standard version works for you will depend on your return on investment. Smaller companies with only a small number of projects may not be able to stomach it, you get a full featured product that is supported by a well established company.  The more projects and the more code you have the greater your return on investment will be. Personally I intend to apply this product to some production systems and will probably have some tips and tricks in the future. del.icio.us Tags: ComponentOne,Studio for Entity Framework,Geeks With Blogs,Influencers,Product Reviews

• SQL SERVER – Why Do We Need Data Quality Services – Importance and Significance of Data Quality Services (DQS)

  - by pinaldave

  Databases are awesome.  I’m sure my readers know my opinion about this – I have made SQL Server my life’s work after all!  I love technology and all things computer-related.  Of course, even with my love for technology, I have to admit that it has its limits.  For example, it takes a human brain to notice that data has been input incorrectly.  Computer “brains” might be faster than humans, but human brains are still better at pattern recognition.  For example, a human brain will notice that “300” is a ridiculous age for a human to be, but to a computer it is just a number.  A human will also notice similarities between “P. Dave” and “Pinal Dave,” but this would stump most computers. In a database, these sorts of anomalies are incredibly important.  Databases are often used by multiple people who rely on this data to be true and accurate, so data quality is key.  That is why the improved SQL Server features Master Data Management talks about Data Quality Services.  This service has the ability to recognize and flag anomalies like out of range numbers and similarities between data.  This allows a human brain with its pattern recognition abilities to double-check and ensure that P. Dave is the same as Pinal Dave. A nice feature of Data Quality Services is that once you set the rules for the program to follow, it will not only keep your data organized in the future, but go to the past and “fix up” any data that has already been entered.  It also allows you do combine data from multiple places and it will apply these rules across the board, so that you don’t have any weird issues that crop up when trying to fit a round peg into a square hole. There are two parts of Data Quality Services that help you accomplish all these neat things.  The first part is DQL Server, which you can think of as the hardware component of the system.  It is installed on the side of (it needs to install separately after SQL Server is installed) SQL Server and runs quietly in the background, performing all its cleanup services. DQS Client is the user interface that you can interact with to set the rules and check over your data.  There are three main aspects of Client: knowledge base management, data quality projects and administration.  Knowledge base management is the part of the system that allows you to set the rules, or program the “knowledge base,” so that your database is clean and consistent. Data Quality projects are what run in the background and clean up the data that is already present.  The administration allows you to check out what DQS Client is doing, change rules, and generally oversee the entire process.  The whole process is user-friendly and a pleasure to use.  I highly recommend implementing Data Quality Services in your database. Here are few of my blog posts which are related to Data Quality Services and I encourage you to try this out.

• Integrating JavaFX Scene Builder in the IDEs

  - by Jerome Cambon

  I experienced recently using Scene Builder from Netbeans, Eclipse and IntelliJ IDEA. As you may know, Scene Builder is a standalone tool, that can be used independently of any IDE. But it can be very convenient to use it with your favorite IDE, for instance start it by double-clicking on an FXML file, or run samples delivered with Scene Builder.  I'm sharing here with you few tweaks that I had to do for a better integration. Scene Builder 1.1 Developer Preview should be installed before doing the tweaks. The steps below have been done on Windows 7. It should be very similar on both Mac OS and Linux. Please tell me if you find any issue on one of these 2 platforms. Netbeans 7.3 Netbeans 7.3 can be downloaded from here. Creating a New FXML project Part of the JavaFx projects, Netbeans allows to create a 'JavaFX FXML Application', that creates a JavaFx project based on FXML description. The FXML file will be editable with Scene Builder. Starting Scene Builder from Netbeans If SceneBuilder 1.1 is installed, Netbeans will discover it automatically.In case of issue, one can open the Options panel, Java section, JavaFx tab. Scene Builder home should appear here. You can then either Open the FXML file with Scene Builder, or edit it with the Netbeans FXML editor : When 'Open' is selected, Scene Builder appears on top of the Netbeans window : When 'Edit' is selected, the FXML is opened in the Netbeans FXML editor, which support syntax highlighting and completion : Using Scene Builder Samples Scene Builder provides Netbeans projects, that can be opened/run directly : Eclipse 4.2.1 + e(fx)clipse 0.1.1 JavaFX integration in Eclipse has been done with the e(fx)clipse plugin. A distribution bundle containing Eclipse and e(fx)clipse is provided here. Creating New FXML project All the JavaFX-related projects can be found in 'Other' section : First create a new JavaFX project: Enter the project name (Test here). JavaFX delivery will be found in the JRE. Then, create a 'New FXML Document': Enter the FXML file name (Sample here). You may also want to choose the FXML document root element (AnchorPane by default). Dynamic root is for advanced users which want to manage custom types. Starting Scene Builder from Eclipse Once created, you can then either Open the FXML file with Scene Builder, or Open it in the Eclipse FXML editor : Using Scene Builder Samples from Eclipse To use Scene Builder samples, first create a new JavaFX Project (from 'Other' section): Then, on the next panel, 'Link additionnal source': … and select the source directory of a Scene Builder example : HelloWorld here (the parent directory of the java package should be selected).Then, choose a 'Folder name' for your sample: You can now run the Scene Builder example by right-clicking the Main.java source file: IntelliJ IDEA 11.1.3 IntelliJ IDEA Community Edition can be downloaded from here. IntelliJ IDEA has no specific JavaFX integration. Creating New IntelliJ project from existing source Since IntelliJ has no JavaFX project knowledge, we are using the Scene Builder samples as a starting point. We are going to create a new Java project from the HelloWorld sample: Then, click twice on 'Next' (nothing to change), then 'Finish'. The 'HelloWorld' project is created. Starting Scene Builder from IntelliJ We need to tell the IDE that FXML files are opened with an external application. Then, the OS file association will be used. To do this, open the File->Settings panel. Then, select 'File Types' and 'Files opened in associated applications'. And add a new wildcard : '*.fxml' : Now, from the HelloWorld project, you can double-click on HelloWorld.fxml : Scene Builder window appears on top of the IntelliJ window : Using Scene Builder Samples from IntelliJ We need to tell IntelliJ that the fxml files must be copied in the build directory.To do that, from the HelloWorld directory, open the 'idea' section, and edit the 'compiler.xml' file. We need to add an '*.fxml' entry: Then, you can run the sample from HelloWorld project, by right-clicking the Main class:

• PHP and Ruby: how to leverage both? and, is it worth it?

  - by dukeofgaming

  As you might have noticed from the title, this is not a "PHP or Ruby", or a "PHP vs. Ruby" question. This is a question on how to leverage PHP + Ruby in the same business. I myself am a PHP developer, I love the language because of its convenience and I specially love the ecosystem of resources that surround it: Joomla, Drupal, Wordpress, Symfony2, Doctrine2, etc. However, the language itself can be a little disappointing sometimes. OTOH, Ruby looks like a very beautiful language and —from studying it superficially in several aspects— I could say it is leaner than Python as a language per se. However, from what I've seen there is pretty much only RoR making noise, and I don't like RoR so much (mainly because its model layer). As Co-CEO and CTO at my company I'm trying to think outside of the box since I want to start to focus on the human side of technology and see if its sane to use both PHP and Ruby. Here are some random thoughts: Ruby folk seem to be generally better suited programmers than PHP folk (in terms of averages), I know the previous statement is somewhat baloney because very good and well architected PHP can be written, but I'd say the Ruby programmer culture is better than PHP's. The thing about Ruby is that it seems better suited for rapid development, I don't really know if this is only the case for RoR, but I do know that there are certain practices (perhaps not so good) like monkey patching that let business needs be satified quicker. From a marketing point of view (yep, sometimes you need to leverage the marketing BS for the sake of your company) Ruby seems better while PHP carries some stigmas. PHP 5.4 is bringing traits, and that is better/cleaner than mixins. That could really make PHP as lean as Ruby —or more— for certain stuff. Now, concretely, my questions: Would a PHP programmer want to learn Ruby?, I know I do, but conversely, would a Ruby programmer want to learn PHP?. What kinds of projects or situations would be better suited for Ruby that are not suited for PHP?. What is the actual ecosystem of Ruby?, aside from RoR, I have not seen other hyped technologies/frameworks (I've seen RSpec, but I confess being a total noob on what BDD really consists of and its implications). Supposing there are a certain type of projects ideal for Ruby, would there be a moment that its better to move it to PHP?. I know PHP can handle lots of stuff, but I've read that Ruby has its limitations when scaling (or is that RoR?, or is that baloney for both?). Finally and most importantly, would it be sane to maintain projects in two languages?, or is that just stupid. As I said, it looks like Ruby is leaner on the short term and that can make a project happen and succeed, but I'm not so sure about that on the long run. I'm looking for insights mainly from people that know well the strengths and weaknesses of the languages —preferably both of them— and Ruby's ecosystem in real practice, meaning: frameworks and applications like the ones I quoted from PHP's ecosystem. Best regards and thanks for your time.

• Tip on Reusing Classes in Different .NET Project Types

  - by psheriff

  All of us have class libraries that we developed for use in our projects. When you create a .NET Class Library project with many classes, you can use that DLL in ASP.NET, Windows Forms and WPF applications. However, for Silverlight and Windows Phone, these .NET Class Libraries cannot be used. The reason is Silverlight and Windows Phone both use a scaled down version of .NET and thus do not have access to the full .NET framework class library. However, there are many classes and functionality that will work in the full .NET and in the scaled down versions that Silverlight and Windows Phone use.Let’s take an example of a class that you might want to use in all of the above mentioned projects. The code listing shown below might be something that you have in a Windows Form or an ASP.NET application. public class StringCommon{  public static bool IsAllLowerCase(string value)  {    return new Regex(@"^([^A-Z])+$").IsMatch(value);  }   public static bool IsAllUpperCase(string value)  {    return new Regex(@"^([^a-z])+$").IsMatch(value);  }} The StringCommon class is very simple with just two methods, but you know that the System.Text.RegularExpressions namespace is available in Silverlight and Windows Phone. Thus, you know that you may reuse this class in your Silverlight and Windows Phone projects. Here is the problem: if you create a Silverlight Class Library project and you right-click on that project in Solution Explorer and choose Add | Add Existing Item… from the menu, the class file StringCommon.cs will be copied from the original location and placed into the Silverlight Class Library project. You now have two files with the same code. If you want to change the code you will now need to change it in two places! This is a maintenance nightmare that you have just created. If you then add this to a Windows Phone Class Library project, you now have three places you need to modify the code! Add As LinkInstead of creating three separate copies of the same class file, you want to leave the original class file in its original location and just create a link to that file from the Silverlight and Windows Phone class libraries. Visual Studio will allow you to do this, but you need to do one additional step in the Add Existing Item dialog (see Figure 1). You will still right mouse click on the project and choose Add | Add Existing Item… from the menu. You will still highlight the file you want to add to your project, but DO NOT click on the Add button. Instead click on the drop down portion of the Add button and choose the “Add As Link” menu item. This will now create a link to the file on disk and will not copy the file into your new project. Figure 1: Add as Link will create a link, not copy the file over. When this linked file is added to your project, there will be a different icon next to that file in the Solution Explorer window. This icon signifies that this is a link to a file in another folder on your hard drive.   Figure 2: The Linked file will have a different icon to show it is a link. Of course, if you have code that will not work in Silverlight or Windows Phone -- because the code has dependencies on features of .NET that are not supported on those platforms – you  can always wrap conditional compilation code around the offending code so it will be removed when compiled in those class libraries. SummaryIn this short blog entry you learned how to reuse one of your class libraries from ASP.NET, Windows Forms or WPF applications in your Silverlight or Windows Phone class libraries. You can do this without creating a maintenance nightmare by using the “Add a Link” feature of the Add Existing Item dialog. Good Luck with your Coding,Paul Sheriff ** SPECIAL OFFER FOR MY BLOG READERS **Visit http://www.pdsa.com/Event/Blog for a free video on Silverlight entitled Silverlight XAML for the Complete Novice - Part 1.

• RC of Entity Framework 4.1 (which includes EF Code First)

  - by ScottGu

  Last week the data team shipped the Release Candidate of Entity Framework 4.1.  You can learn more about it and download it here. EF 4.1 includes the new “EF Code First” option that I’ve blogged about several times in the past.  EF Code First provides a really elegant and clean way to work with data, and enables you to do so without requiring a designer or XML mapping file.  Below are links to some tutorials I’ve written in the past about it: Code First Development with Entity Framework 4.x EF Code First: Custom Database Schema Mapping Using EF Code First with an Existing Database The above tutorials were written against the CTP4 release of EF Code First (and so some APIs might be a little different) – but the concepts and scenarios outlined in them are the same as with the RC. Go Live License Last week’s EF 4.1 RC ships with a “go live” license that enables you to use it in production environments.  The final release of EF 4.1 will ship within the next 4 weeks and will be 100% API compatible with the RC release. Improvements with the RC The RC includes several improvements and enhancements.  The EF team has a good blog post summarizing the RC changes.  Scott Hanselman also has a nice video interview with the data team that talks more about the release. One of my favorite improvements introduced with last week’s RC is its support for medium trust security.  This enables you to use EF 4.1 (and code-first) within low-cost ASP.NET shared hosting web environments – without requiring a hoster to install anything to use it. EF 4.1 also now supports validation with not only code-first scenarios, but also model-first and database-first workflows.  Upgrading from previous releases The RC does include a few API tweaks and changes from the prior CTP builds.  Read the release notes that come with the release to get a more detailed listing of the changes. John Papa also has an excellent Upgrading to EF 4.1 RC blog post that describes the steps he took when upgrading a large project he wrote with the previous CTP5 release.  The work to upgrade is pretty straight forward and easy – use his write-up as a guide on how to quickly update projects of your own. NuGet Package Rename One of the changes that the data team made between the CTP5 and RC releases was to rename the NuGet package name from “EFCodeFirst” to “EntityFramework”. They decided to make this change since the EF 4.1 release now includes several additions above and beyond just code first. If you already have installed the “EFCodeFirst” NuGet package, you’ll want to uninstall it and then install the new “EntityFramework” NuGet package.  John Papa’s blog post details the exact steps on how to do this (it only takes ~20 seconds to do this). More EF Tutorials Julie Lerman has created some nice whitepapers and tutorials for MSDN that show using the new EF4 and EF 4.1 feature set. Click here to find links to read and watch them. Summary I’m really excited about the EF 4.1 release that will be shipping next month.  It significantly improves the Entity Framework, and makes it even easier and cleaner to work with data inside of .NET.  You can take advantage of it within all ASP.NET projects (including both Web Forms and MVC), within client projects using Windows Forms and WPF, and within other project types like WCF, Console and Services.  You can use NuGet to easily install it within all of them. Hope this helps, Scott P.S. I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

• Apache config that uses two document roots based on whether the requested resource exists in the first [closed]

  - by mattalexx

  Background I have a client site that consists of a CakePHP installation and a Magento installation: /web/example.com/ /web/example.com/app/ <== CakePHP /web/example.com/app/webroot/ <== DocumentRoot /web/example.com/app/webroot/store/ <== Magento /web/example.com/config/ <== Site-wide config /web/example.com/vendors/ <== Site-wide libraries The server runs Apache 2.2.3. The problem The whole company has FTP access and got used to clogging up the /web/example.com/, /web/example.com/app/webroot/, and /web/example.com/app/webroot/store/ directories with their own files. Sometimes these files need HTTP access and sometimes they don't. In any case, this mess makes my job harder when it comes to maintaining the site. Code merges, tarring the live code, etc, is very complicated and usually requires a bunch of filters. Abandoned solution At first, I thought I would set up a new subdomain on the same server, move all of their files there, and change their FTP chroot. But that wouldn't work for these reasons: Firstly, I have no idea (and neither do they remember) what marketing materials they've sent out that contain URLs to certain resources they've uploaded to the server, using the main domain, and also using abstract subdomains that use the main virtual host because it has ServerAlias *.example.com. So suddenly having them only use static.example.com isn't feasible. Secondly, The PHP scripts in their projects are potentially very non-portable. I want their files to stay in as similar an environment as they were built as I can. Also, I do not want to debug their code to make it portable. Half-baked solution After some thought, I decided to find a way to section off the actual website files into another directory that they would not touch. The company's uploaded files would stay where they were. This would ensure that I didn't break any of their projects that needed HTTP access. It would look something like this: /web/example.com/ <== A bunch of their files are in here /web/example.com/app/webroot/ <== 1st DocumentRoot; A bunch of their files are in here /web/example.com/app/webroot/store/ <== Some more are in here /web/example.com/site/ <== New dir; Contains only site files /web/example.com/site/app/ <== CakePHP /web/example.com/site/app/webroot/ <== 2nd DocumentRoot /web/example.com/site/app/webroot/store/ <== Magento /web/example.com/site/config/ <== Site-wide config /web/example.com/site/vendors/ <== Site-wide libraries After I made this change, I would not need to pay attention to anything except for the stuff within /web/example.com/site/ and my job would be a lot easier. I would be the only one changing stuff in there. So here's where the Apache magic would happen: I need an HTTP request to http://www.example.com/ to first use /web/example.com/app/webroot/ as the document root. If nothing is found (no miscellaneous uploaded company projects are found), try finding something within /web/example.com/site/app/webroot/. Another thing to keep in mind is, the site might have some problems if the $_SERVER['DOCUMENT_ROOT'] variable reads /web/example.com/app/webroot/ but the actual files are within /web/example.com/site/app/webroot/. It would be better if the DOCUMENT_ROOT environment variable could be /web/example.com/site/app/webroot/ for anything within the /web/example.com/site/app/webroot/ directory. Conclusion Is my half-baked solution possible with Apache 2.2.3? Is there a better way to solve this problem?

• TortoiseSVN hangs in Windows Server 2012 Azure VM

  - by ZaijiaN

  Following @shanselman's article on remoting into an Azure VM for development, I spun up my own VS 2013 VM, and that image runs on WS 2012. Once I was able to remote in, I started installing all my dev tools, including Tortoise SVN 1.8.3 64bit. Things went south once I started attempting to check out code from my personal svn server. It would hang and freeze often, although sometimes it would work - I was able to partially check out projects, but I would get frequent connection time out errors. My personal svn server (VisualSVN 2.7.2) runs at home on a windows 7 machine, and I have a dyndns url pointing to it. I have also configured my router to passthrough all 443 traffic to the appropriate port on the server. I self-signed a cert and made sure it was imported into the VM cert store under trusted root authorities. I have no problems connecting to my svn server from 4-5 other computers & locations. From the Azure VM, in both IE and Chrome, I can access the repository web browser with no issues. There are no outbound firewall restrictions. I have installed other SVN add-ons for Visual Studio (AnkhSVN, VisualSVN) and attempted to connect with my svn server, with largely the same results - random and persistent connection issues (hangs/timeouts). I spun up a completely fresh WS 2008 Azure VM, and installed TortoiseSVN, and had the same results. So I'm at a loss as to what the problem is and how to fix it. Web searches on tortoisesvn and windows server issues doesn't yield any current or relevant information. At this point, i'm guessing that maybe some setting or configuration that MS Azure VM images is the culprit - although I should probably attempt to spin up my own local WS VM to rule out that it's a window server issue. Any thoughts? I hope I'm just missing something really obvious!

• Makecert.exe hangs

  - by Robert

  I was following the steps in Scott Hanselman's blog post describing how to create a certificate authority and code signing certificate for PowerShell scripts. Initially, I created the certificate authority and a personal certifcate and used it to sign a powershell script successfully. All went as described in the blog post. The problem starts (as most do) when I did something that was (probably) stupid, although it seemed reasonable at the time. I wanted to start over and repeat the process again with a clean slate, so from the mmc certificates snap-in console, I deleted the personal certificate and the certificate authority I created previously. After that any time I try to use makecert, (just as I did the first time around), makecert either hangs or faults (which prompts to end or debug). Did I hose something up by deleting via the certificates snap-in? It didn't complain or warn me that it could be potentially hazardous. Is this just coincidence and something else entirely could be hosed? I have Event Log entries from the times when makecert crashed, which all look very similar; here is one: Log Name: Application Source: Application Error Date: 8/5/2009 3:55:04 PM Event ID: 1000 Task Category: (100) Level: Error Description: Faulting application makecert.exe, version 6.0.6000.16384, time stamp 0x4545910b, faulting module ntdll.dll, version 6.0.6002.18005, time stamp 0x49e03821, exception code 0xc0000005, fault offset 0x00067409, process id 0xe58, application start time 0x01ca160efdf30625. Anyone have any ideas as to what exactly caused this and/or what I can do to fix it. I'm on 32-bit Vista Enterprise w/SP2.

• Easiest way to send encrypted email?

  - by johnnyb10

  To comply with Massachusetts's new personal information protection law, my company needs to (among other things) ensure that anytime personal information is sent via email, it's encrypted. What is the easiest way to do this? Basically, I'm looking for something that will require the least amount of effort on the part of the recipient. If at all possible, I really want to avoid them having to download a program or go through any steps to generate a key pair, etc. So command-line GPG-type stuff is not an option. We use Exchange Server and Outlook 2007 as our email system. Is there a program that we can use to easily encrypt an email and then fax or call the recipient with a key? (Or maybe our email can include a link to our website containing our public key, that the recipient can download to decrypt the mail?) We won't have to send many of these encrypted emails, but the people who will be sending them will not be particularly technical, so I want it to be as easy as possible. Any recs for good programs would be great. Thanks.

• Exchange 2010 POP3/IMAP4/Transport services complaining that they can't find SSL certificate after blue screen

  We have a single-server Exchange 2010 setup. In the early hours of this morning the server had a blue screen and rebooted. After coming back up the POP3/IMAP4 and Transport services are complaining that they cannot find the correct SSL certificate for mail.example.com. POP3: Log Name: Application Source: MSExchangePOP3 Date: 2012/04/23 11:45:15 AM Event ID: 2007 Task Category: (1) Level: Error Keywords: Classic User: N/A Computer: exch01.domain.local Description: A certificate for the host name "mail.example.com" couldn't be found.

Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key. The odd part is that Get-ExchangeCertificate show the cert as enabled for all the relevant services, and OWA is working flawlessly using this certificate.

• Automated software installation for MS Windows?

  - by Duncan Bayne

  I am currently setting up a Windows development environment (the whole Visual Studio 2010 stack plus plugins on top of Windows 7). This has got me wondering whether there's a Windows equivalent to what I do for dev environment setup in Ubuntu. It takes literally hours to get a dev environment set up in Windows, involving a lot of manual intervention. On Ubuntu, I have two shell scripts - one I run as root which configures the system using apt-get (amongst other things), one I run as me which configures my user account. Those scripts live in my private Subversion repository. To set up a dev environment from scratch requires five commands: sudo apt-get install -y subversion svn co http://svn.XXXX.XXX/personal/ cd personal sudo ./ubuntu_setup_root.sh ./ubuntu_setup_user.sh The only human intervention required is to pick a root password for MySQL. So it takes only a few minutes of human attention to go from a vanilla Ubuntu installation to a full development environment with the latest builds of everything, perfectly tailored down to shortcut keys and wallpaper. Is there an equivalent process for Windows? In an ideal world it'd be something trivially scriptable using C# Script or Powershell, which could live in source control & make use of a repository of ISOs downloaded from MSDN ...

• Add files/folders/Apps to a new User Account

  - by odeho19

  I have created a new user acct. for my roommate. I/we don't really care much for IE, and I'd like to add Google Chrome, and FF for her, to let her choose her own browser. Plus I'd like to add some other apps for her, and transfer some of her personal info that she's been storing on my administrative acct. (i.e. personal photos and such). So, like I said the account is set up. But when I go to use Chrome, it won't open. It, along with other apps are listed in the list of "approved" applications under the parental control list. (Application Restrictions List) But they either don't show up when searched for,( in her acct.) or won't open and operate. One other example is Faststone Capture. And then, I've got one application, Yahoo, "Unchecked", and yet there it is in her account, AND IT WORKS! I do not get it. The purpose to setting up an account for her was to only restrict that she couldn't delete, or uninstall anything on the computer. I don't care, (obviously within reason) what she installs, but NO TAKING AWAY! lol Here is a screen shot of the restrictions list: So, here I sit, wondering what I did wrong, or forgot to do in order for these to work. I don't care if Yahoo works or not. But her photos being transferred, Chrome/FF working, and Faststone Capture working, are a priority for me. If anyone has any ideas, I would appreciate any advice. Thanks! OH Edit: Also, my account is an Administrative one. The account I am creating for her is just a Standard User Acct.

• Troubleshooting wireless client-bridged networks between two DD-WRT routers?

  - by KronoS

  I recently purchased a Buffalo N600 wireless router which came with DD-WRT pre-installed. I want to take my old wireless router a Linksys WRT54GL, also with DD-WRT pre-installed, and use it as a wireless bridge for my HTPC and Blu-Ray Player in the other room. I other words, I'm trying to connect to WIRED networks via the wireless on the routers. I followed eactly the instruction from DD-WRT's manual for 'Client Bridged' however I'm still not able to connect to two routers correctly, when the encryption is enabled (WPA2-Personal Mixed) however I am able to connect the two routers when there is NO encryption. I've checked, double checked, and triple checked that EVERYTHING is the same on BOTH routers: Routers 1 & 2 Encryption: WPA2-Personal Mixed Wireless Mode: G-Only Wireless Channel: 6 Subnet Mask: 255.255.255.0 Subnet: 192.168.1.0/254 SSID: Krono$ Primary Router #1 (Buffalo N600) IP Address: 192.168.1.1 Firewall: Enables w/ defaults DCHP: Enabled as DHCP Server Secondary Router #2 (Linksys WRT54GL) IP Address: 192.168.1.2 Firewall: Disabled as per DD-WRT instructions I'm looking for any configurations that I may have missed, or settings that may need to happen in order for this work.

• Using Truecrypt to secure mySQL database, any pitfalls?

  - by Saul

  The objective is to secure my database data from server theft, i.e. the server is at a business office location with normal premises lock and burglar alarm, but because the data is personal healthcare data I want to ensure that if the server was stolen the data would be unavailable as encrypted. I'm exploring installing mySQL on a mounted Truecrypt encrypted volume. It all works fine, and when I power off, or just cruelly pull the plug the encrypted drive disappears. This seems a load easier than encrypting data to the database, and I understand that if there is a security hole in the web app , or a user gets physical access to a plugged in server the data is compromised, but as a sanity check , is there any good reason not to do this? @James I'm thinking in a theft scenario, its not going to be powered down nicely and so is likely to crash any DB transactions running. But then if someone steals the server I'm going to need to rely on my off site backup anyway. @tomjedrz, its kind of all sensitive, individual personal and address details linked to medical referrals/records. Would be as bad in our field as losing credit card data, but means that almost everything in the database would need encryption... so figured better to run the whole DB in an encrypted partition. If encrypt data in the tables there's got to be a key somewhere on the server I'm presuming, which seems more of a risk if the box walks. At the moment the app is configured to drop a dump of data (weekly full and then deltas only hourly using rdiff) into a directory also on the Truecrypt disk. I have an off site box running WS_FTP Pro scheduled to connect by FTPs and synch down the backup, again into a Truecrypt mounted partition.

• Can a non-redundant RAID5 cause any serious problems (compared to RAID0)?

  - by leemes

  I used to have a three-disc RAID5 (mdadm) in my computer for personal media storage (music, videos, photos, programs, games, ...). It had three discs with 750 GB each, resulting in an array capacity of 1.5 TB. One day (one year ago), I needed one of those discs to install another operating system. I thought, I don't need the redundancy anymore since I backup the most important stuff (personal photos e.g.) on an external disc anyway. So I decided to remove one of the three discs without converting the RAID to RAID0 or even two separate discs, because I had no temporary storage (since one cannot simply convert the RAID5 to RAID0 AFAIK). So now, for about one year, I have a non-redundant RAID5 with 2 of 3 discs running. Sometimes, one of the discs has a defective contact at the power cable or something similar causing the drive to stop working temporarily (I don't know exactly what it is). Since it still works when rebooting the computer and in most cases by calling some mdadm commands, it wasn't that problematic. Note that the data is not very critical, since I still have a backup of the most important stuff. But in the last few weeks, one of the drives fails very frequently (every few hours), so it gets really annoying to manage this. My questions are: Is there any disadvantage (apart from the annoying management) of a non-redundant RAID5 (with one drive less than typical) over a RAID0? If I understand it correctly, both have no redundancy and the same capacity. On a temporary drive failure, I can restart the array in both cases, assuming that the drive itself still works after the failure. Can it happen that the drive contents alter on a drive failure, making the array inconsistent? If so, can I tell mdadm to check the array for failures (without a file system level checking tool)? Since the drive most probably only has a defective contact causing it to fail for a second only, can I tell mdadm to automatically restart the array, so I will not even notice the failure if no application wanted to access the file system during the failure?

• How to backup Servers to an SSH-Host with low traffic and access to versions and encryption?

  - by leto

  Hello, I've not run backups for the past dont't remember anymore years for my personal stuff until waking up lately and realising contrary to my prior belief: Actually. I care! :) Now I have a central data server at home where I want to attach an external media to, to which I want to save backups of my most important stuff, like years of self-written scripts, database dumps, you name it. I've tinkered with rsync+ssh over the last two years, also tried tar over ssh, but don't know the simplest and most easy to maintain way to do it yet. Heres my workload: A typical LAMP-Server (<5GB Data) which I'd like to backup fully so lots of small files connected via 10Mbit My personal stuff (<750GB Data) from a Mac connected via GE My passwords in an encrypted container (100Mb) from OpenBSD connected via serial-PPP My E-Mail from the last ten years (<25GB) as Maildir which I need to keep in readable format Some archives (tar.*) which I need to backup only once and keep in readable format (Deleted my ideas, as I'm here for suggestions) What I need: 1. Use an ssh-tunnel for data transfer 2. Be quick with lots of small files 3. Keep revisions 4. Be sure the data I save is not corrupted 5. Intelligent resume functions and be able to deal with network congestion :) 6. Compressed and optionally encrypted storage 7. Be able to extract data from backup easily (filesystem like usage would be nice) How would and with what software would you backup this stuff? Hints to tools that can help solve only part of my problem (like encryption) also greatly appreciated. Greets

• MacMini transmit rate stuck at 11, every other device can connect at full 54Mbit/s?

  - by chum of chance

  I have a MacMini circa 2007 that's getting very low transmit rates via wifi, 8-11. I have other devices that are getting full 54, including a MacBook Air. With everything else off, the MacMini doesn't want to seem to go any faster. Since it has been previously connected to ethernet its entire life, I was wondering if there were some settings I can change to speed up the connection. Option-clicking the network icon gives this read out: PHY Mode: 802.11g Channel: 1 (2.4 Ghz) Security: WPA2 Personal RSSI: -73 Transmit Rate: 11 My new MacBook Air has the following readout: PHY Mode: 802.11n Channel: 1 (2.4 Ghz) Security: WPA2 Personal RSSI: -66 Transmit Rate: 79 Both have full bars and the wireless router is in the same room to eliminate any obstructions from the equation. Could the MacMini be connecting at an older protocol, like 802.11b and be reporting erroneously that it is connected at 802.11g? This would explain why I haven't seen a transmit rate above 11. Any further trouble shooting I can try before buying a new USB 802.11n device? The WiFi router is a DLink DIR-615. I can see other devices, and none, even the other g connected devices, are getting below 30-40 MBit/s. What's going on here?

• BYOD (accessing files) on a domain without joining?

  - by Philip White

  I run a Samba 4 instance at a small private school. This makes a regular Linux server appear as a directory controller. There are two relevant benefits to this: I have a Samba share for people's documents, and I use the Redirected Folders feature to allow any employee to sit down at any PC, log in with their domain credentials, and their My Documents points to network storage. Everyone has a mapped drive (using Group Policy Preferences) to a share specific to their account type. Students can access one share (one share for all students), teachers have another, and office staff have another. However, I would like to allow BYOD (Bring Your Own Device). Some employees are already asking for it with their personal laptops, and I know eventually most everyone will want to. Is there any way to replicate the two features above without having to join PCs to the domain? Joining personal PCs is impractical if only because only professional editions of Windows support this. Ideally, any operating system (including mobile) could access the relevant shares, but of course Windows is key. Offline caching is optional. (I could set up OpenVPN for teachers who want to access their files from home.) The problem with simply giving SSH access to the relevant shares is primarily that Samba 4 relies on ext4 ACLs and ext4 extended attributes to maintain NTFS permissions. Writing files directly to the Linux server would bypass this and would (probably) not be interoperable with Samba4. Right now I am completely flexible. I am even fine with scrapping the whole domain and using some other software for the two features above. How can I allow school employees and students freedom to securely share files without requiring everyone to have specific editions of Windows?
