  • Cryptographic Validation Explained

    - by MarkPearl
    We have been using LogicNP’s CryptoLicensing for some of our software and I was battling to understand how exactly the whole process worked. I was sent the following document which really helped explain it – so if you ever use the same tool it is well worth a read. Licensing Basics LogicNP CryptoLicensing For .Net is the most advanced and state-of-the art licensing and copy protection system you can use for your software. LogicNP CryptoLicensing System uses the latest cryptographic technology to generate and validate licenses. The cryptographic algorithm used is the RSA algorithm which consists of a pair of keys called as the generation key and the validation key. Data encrypted using the generation key can only be decrypted using the corresponding validation key. How does cryptographic validation work? When a new license project is created, a unique validation-generation key pair is created for the project. When LogicNP CryptoLicensing For .Net generates licenses, it encrypts the license settings using the generation key. The validation key can be safely distributed with your software and is used during validation. During license validation, LogicNP CryptoLicensing For .Net attempts to decrypt the encrypted license code using the validation key. If the decryption is successful, this means that the data was encrypted using the generation key, since only the corresponding validation key can decrypt data encrypted with the generation key. This further means that not only is the license valid but that it was generated by you and only you since nobody else has access to the generation key. Generation Key This key is used by CryptoLicensing Generator to generate encrypted license codes. This key is stored in the license project file, so the license project file must be kept secure and confidential and must be accorded the same care as any other critical asset such as source code. Validation Key This key is used for validating generated license codes. It is the same key displayed in the 'Get Validation Key And Code' dialog (Ctrl+K) and is used by your software when validating license codes (using LogicNP.CryptoLicensing.dll). Unlike the generation key, it is not necessary to keep this key secure and confidential. Note that the generation key pair is stored in the project file created by LogicNP CryptoLicensing For .Net, so it is very important to backup this file and to keep it secure. Once the file is lost, it is not possible to retrieve the key pair. FAQ Do I use the same validation key to validate all license codes? Yes, the validation key (and generation key) for the project remains the same; you use the same key to validate all license codes generated using the project. You can retrieve the validation key using the "Project" menu --> "Get Validation Key & Code" menu item. Can license codes generated using generation key from one project be validated using validation key of another project? No! Q. Is every generated license code unique? A. Yes, every license code generated by CryptoLicensing is guaranteed to be unique, even if you generate thousands of codes at a time. Q. What makes CryptoLicensing so secure? A. CryptoLicensing uses the latest cryptographic technology to generate and validate licenses. The cryptographic algorithm used is the RSA asymmetric key algorithm which can use upto 3072-bit keys. Given current computing power, it takes years to break a 3072-bit key. Q. Is is possible for a hacker to develop a keygen for my software? A. Impossible. The cryptographic algorithm used by CryptoLicensing consists of a pair of keys called as the generation key and the validation key. Data encrypted with one key can only be decrypted by the other key and vice versa. Licenses are generated using the generation key and validated using the validation key. Without the generation key, it is impossible to generate valid licenses. Q. What is the difference between validation key and generation key? Generation Key This key is used by CryptoLicensing Generator to generate encrypted license codes. This key is stored in the license project file, so the license project file must be kept secure and confidential and must be accorded the same care as any other critical asset such as source code. Validation Key This key is used for validating generated license codes. It is the same key displayed in the 'Get Validation Key And Code' dialog (Ctrl+K) and is used by your software when validating license codes (using LogicNP.CryptoLicensing.dll). Unlike the generation key, it is not necessary to keep this key secure and confidential. Q. Do I have to include the license project file (.licproj) with my software? A. No!!! This goes against the very essence of the security of the asymmetric cryptographic scheme because the project file contains both the validation and generation key. With your software, you only need to include the validation key which will be used to validate licenses generated by CryptoLicensing using the generation key. The license project file should be treated as any other valuable and confidential asset such as your source code. Q. Does the license service need the license project file? A. Yes. The license project file is needed whenever new licenses are generated (via the UI, via the API or via the license service). As just one example, the license service generates new machine-locked licenses when activated licenses are presented to it for activation, therefore the license service needs the license project file. Q. Is it possible to embed my own data in the generated licenses? A. Yes. You can embed any amount of additional data in the licenses. This data will have the same amount of security as the license code itself and will be tamper-proof. The embedded user data can be retrieved from your software. Q. What additional steps can I take to ensure that my software does not get cracked? A. There are many methods and techniques which can make it extremely difficult for a hacker to crack your software. See Writing Effective License Checking Code And Designing Effective Licenses for more information. Q. Why is the license service not working? A. The most common cause is not setting the CryptoLicense.LicenseServiceURL property before trying to validate a license. Make sure that this property is set to the correct URL where your license service is hosted. The most common cause after this is that the license project file on the web server where your license service is hosted is not the latest. This happens if you make changes to the license project (for example, set the 'Enable With Serials' setting for a profile), but don't upload the updated project file to your web server. Q. Why are my serials not working? Serial codes require the user of a license service. See Using Serial Codes for more details. Also see the earlier question 'Why is the license service not working?' Q. Is the same validation key used to validate license codes generated from different profiles. A. Yes. Profiles are just pre specified license settings for quickly generating licenses having those settings. The actual license code is still generated using the license project's cryptographic generation key and thus, can be validated using the project's validation key. Q. Why are changes made to a profile not getting saved? A. Simply changing license settings via UI and saving the license project does not save those license settings to the active profile. You must first save the license settings to a profile using the Save/Save As command from the Profiles menu (see above). Q. Why is validation of activated licenses failing from CryptoLicensing Generator, but works from my software? A. Make sure that you have specified the URL of the license service using the Project Properties Dialog. Also see the earlier question 'Why is the license service not working?' Q. How can I extend the trial period of my customer? A. To extend the evaluation period of the customer, simply send him a new license code specifying the desired evaluation limits. Evaluation information such as the current used days, executions, etc are stored in garbled form in a registry location which is derived from the license code. Therefore, when a new license code is used, the old evaluation information will not be used and a new evaluation period will be started.

  • Standards Corner: OAuth WG Client Registration Problem

    - by Tanu Sood

Being an active voice in the industry standards development world, we have invited him to share his discussions, thoughts, news & updates, and discuss use cases, implementation success stories (and even failures) around industry standards on this monthly column. Author: Phil Hunt This afternoon, the OAuth Working Group will meet at IETF88 in Vancouver to discuss some important topics important to the maturation of OAuth. One of them is the OAuth client registration problem.OAuth (RFC6749) was initially developed with a simple deployment model where there is only monopoly or singleton cloud instance of a web API (e.g. there is one Facebook, one Google, on LinkedIn, and so on). When the API publisher and API deployer are the same monolithic entity, it easy for developers to contact the provider and register their app to obtain a client_id and credential.But what happens when the API is for an open source project where there may be 1000s of deployed copies of the API (e.g. such as wordpress). In these cases, the authors of the API are not the people running the API. In these scenarios, how does the developer obtain a client_id? An example of an "open deployed" API is OpenID Connect. Connect defines an OAuth protected resource API that can provide personal information about an authenticated user -- in effect creating a potentially common API for potential identity providers like Facebook, Google, Microsoft, Salesforce, or Oracle. In Oracle's case, Fusion applications will soon have RESTful APIs that are deployed in many different ways in many different environments. How will developers write apps that can work against an openly deployed API with whom the developer can have no prior relationship?At present, the OAuth Working Group has two proposals two consider: Dynamic RegistrationDynamic Registration was originally developed for OpenID Connect and UMA. It defines a RESTful API in which a prospective client application with no client_id creates a new client registration record with a service provider and is issued a client_id and credential along with a registration token that can be used to update registration over time.As proof of success, the OIDC community has done substantial implementation of this spec and feels committed to its use. Why not approve?Well, the answer is that some of us had some concerns, namely: Recognizing instances of software - dynamic registration treats all clients as unique. It has no defined way to recognize that multiple copies of the same client are being registered other then assuming if the registration parameters are similar it might be the same client. Versioning and Policy Approval of open APIs and clients - many service providers have to worry about change management. They expect to have approval cycles that approve versions of server and client software for use in their environment. In some cases approval might be wide open, but in many cases, approval might be down to the specific class of software and version. Registration updates - when does a client actually need to update its registration? Shouldn't it be never? Is there some characteristic of deployed code that would cause it to change? Options lead to complexity - because each client is treated as unique, it becomes unclear how the clients and servers will agree on what credentials forms are acceptable and what OAuth features are allowed and disallowed. Yet the reality is, developers will write their application to work in a limited number of ways. They can't implement all the permutations and combinations that potential service providers might choose. Stateful registration - if the primary motivation for registration is to obtain a client_id and credential, why can't this be done in a stateless fashion using assertions? Denial of service - With so much stateful registration and the need for multiple tokens to be issued, will this not lead to a denial of service attack / risk of resource depletion? At the very least, because of the information gathered, it would difficult for service providers to clean up "failed" registrations and determine active from inactive or false clients. There has yet to be much wide-scale "production" use of dynamic registration other than in small closed communities. Client Association A second proposal, Client Association, has been put forward by Tony Nadalin of Microsoft and myself. We took at look at existing use patterns to come up with a new proposal. At the Berlin meeting, we considered how WS-STS systems work. More recently, I took a review of how mobile messaging clients work. I looked at how Apple, Google, and Microsoft each handle registration with APNS, GCM, and WNS, and a similar pattern emerges. This pattern is to use an existing credential (mutual TLS auth), or client bearer assertion and swap for a device specific bearer assertion.In the client association proposal, the developer's registration with the API publisher is handled by having the developer register with an API publisher (as opposed to the party deploying the API) and obtaining a software "statement". Or, if there is no "publisher" that can sign a statement, the developer may include their own self-asserted software statement.A software statement is a special type of assertion that serves to lock application registration profile information in a signed assertion. The statement is included with the client application and can then be used by the client to swap for an instance specific client assertion as defined by section 4.2 of the OAuth Assertion draft and profiled in the Client Association draft. The software statement provides a way for service provider to recognize and configure policy to approve classes of software clients, and simplifies the actual registration to a simple assertion swap. Because the registration is an assertion swap, registration is no longer "stateful" - meaning the service provider does not need to store any information to support the client (unless it wants to). Has this been implemented yet? Not directly. We've only delivered draft 00 as an alternate way of solving the problem using well-known patterns whose security characteristics and scale characteristics are well understood. Dynamic Take II At roughly the same time that Client Association and Software Statement were published, the authors of Dynamic Registration published a "split" version of the Dynamic Registration (draft-richer-oauth-dyn-reg-core and draft-richer-oauth-dyn-reg-management). While some of the concerns above are addressed, some differences remain. Registration is now a simple POST request. However it defines a new method for issuing client tokens where as Client Association uses RFC6749's existing extension point. The concern here is whether future client access token formats would be addressed properly. Finally, Dyn-reg-core does not yet support software statements. Conclusion The WG has some interesting discussion to bring this back to a single set of specifications. Dynamic Registration has significant implementation, but Client Association could be a much improved way to simplify implementation of the overall OpenID Connect specification and improve adoption. In fairness, the existing editors have already come a long way. Yet there are those with significant investment in the current draft. There are many that have expressed they don't care. They just want a standard. There is lots of pressure on the working group to reach consensus quickly.And that folks is how the sausage is made.Note: John Bradley and Justin Richer recently published draft-bradley-stateless-oauth-client-00 which on first look are getting closer. Some of the details seem less well defined, but the same could be said of client-assoc and software-statement. I hope we can merge these specs this week.

  • What is your definition of a programmer?

    - by Amir Rezaei
    The definition of a programmer is not obvious. It has happened that I have asked questions in this forum where people believe it don’t belong here because it’s not programmer related. I thought this question may clarify the definition. What characteristics, roles and activities do you think defines a programmer? Is there a typical programmer? The technology changes so fast that it may be hard to be typical programmer. From wikipedia: A programmer, computer programmer or coder is someone who writes computer software. The term computer programmer can refer to a specialist in one area of computer programming or to a generalist who writes code for many kinds of software. One who practices or professes a formal approach to programming may also be known as a programmer analyst. A programmer's primary computer language (C, C++, Java, Lisp, Delphi etc.) is often prefixed to the above titles, and those who work in a web environment often prefix their titles with web. The term programmer can be used to refer to a software developer, software engineer, computer scientist, or software analyst. However, members of these professions typically possess other software engineering skills, beyond programming; for this reason, the term programmer is sometimes considered an insulting or derogatory oversimplification of these other professions. This has sparked much debate amongst developers, analysts, computer scientists, programmers, and outsiders who continue to be puzzled at the subtle differences in these occupations

  • Referencing environment variables *in* /etc/environment?

    - by Stefan Kendall
    I recently discovered /etc/environment, which seems a more standard way to setup simple environment variables than scripts, but I was wondering if there was a way to back-reference environment variables in the /etc/environment file. That is, I have this: JAVA_HOME="/tools/java" GRAILS_HOME="/tools/grails" GROOVY_HOME="/tools/groovy" GRADLE_HOME="/tools/gradle" PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" If I try to add $JAVA_HOME/bin to the PATH definition, however, I get $JAVA_HOME/bin, and not the interpolated variable. To remedy this, I'm creating environment.sh in profile.d to add the /bin entries to the path, but this seems sloppy and disorganized. Is there a way to backreference the environment variables in /etc/environment?

  • SQL SERVER – Integrate Your Data with Skyvia – Cloud ETL Solution

    - by Pinal Dave
    In our days data integration often becomes a key aspect of business success. For business analysts it’s very important to get integrated data from various sources, such as relational databases, cloud CRMs, etc. to make correct and successful decisions. There are various data integration solutions on market, and today I will tell about one of them – Skyvia. Skyvia is a cloud data integration service, which allows integrating data in cloud CRMs and different relational databases. It is a completely online solution and does not require anything except for a browser. Skyvia provides powerful etl tools for data import, export, replication, and synchronization for SQL Server and other databases and cloud CRMs. You can use Skyvia data import tools to load data from various sources to SQL Server (and SQL Azure). Skyvia supports such cloud CRMs as Salesforce and Microsoft Dynamics CRM and such databases as MySQL and PostgreSQL. You even can migrate data from SQL Server to SQL Server, or from SQL Server to other databases and cloud CRMs. Additionally Skyvia supports import of CSV files, either uploaded manually or stored on cloud file storage services, such as Dropbox, Box, Google Drive, or FTP servers. When data import is not enough, Skyvia offers bidirectional data synchronization. With this tool, you can synchronize SQL Server data with other databases and cloud CRMs. After performing the first synchronization, Skyvia tracks data changes in the synchronized data storages. In SQL Server databases (and other relational databases) it creates additional tracking tables and triggers. This allows synchronizing only the changed data. Skyvia also maps records by their primary key values to each other, so it does not require different sources to have the same primary key structure. It still can match the corresponding records without having to add any additional columns or changing data structure. The only requirement for synchronization is that primary keys must be autogenerated. With Skyvia it’s not necessary for data to have the same structure in integrated data storages. Skyvia supports powerful mapping mechanisms that allow synchronizing data with completely different structure. It provides support for complex mathematical and string expressions when mapping data, using lookups, etc. You may use data splitting – loading data from a single CSV file or source table to multiple related target tables. Or you may load data from several source CSV files or tables to several related target tables. In each case Skyvia preserves data relations. It builds corresponding relations between the target data automatically. When you often work with cloud CRM data, native CRM data reporting and analysis tools may be not enough for you. And there is a vast set of professional data analysis and reporting tools available for SQL Server. With Skyvia you can quickly copy your cloud CRM data to an SQL Server database and apply corresponding SQL Server tools to the data. In such case you can use Skyvia data replication tools. It allows you to quickly copy cloud CRM data to SQL Server or other databases without customizing any mapping. You need just to specify columns to copy data from. Target database tables will be created automatically. Skyvia offers powerful filtering settings to replicate only the records you need. Skyvia also provides capability to export data from SQL Server (including SQL Azure) and other databases and cloud CRMs to CSV files. These files can be either downloadable manually or loaded to cloud file storages or FTP server. You can use export, for example, to backup SQL Azure data to Dropbox. Any data integration operation can be scheduled for automatic execution. Thus, you can automate your SQL Azure data backup or data synchronization – just configure it once, then schedule it, and benefit from automatic data integration with Skyvia. Currently registration and using Skyvia is completely free, so you can try it yourself and find out whether its data migration and integration tools suits for you.

  • Inside Red Gate - Introduction

    - by Simon Cooper
    I work for Red Gate Software, a software company based in Cambridge, UK. In this series of posts, I'll be discussing how we develop software at Red Gate, and what we get up to, all from a dev's perspective. Before I start the series proper, in this post I'll give you a brief background to what I have done and continue to do as part of my job. The initial few posts will be giving an overview of how the development sections of the company work. There is much more to a software company than writing the products, but as I'm a developer my experience is biased towards that, and so that is what this series will concentrate on. My background Red Gate was founded in 1999 by Neil Davidson & Simon Galbraith, who continue to be joint CEOs. I joined in September 2007, and immediately set to work writing a new Check for Updates client and server (CfU), as part of a team of 2. That was finished at the end of 2007. I then joined the SQL Compare team. The first large project I worked on was updating SQL Compare for SQL Server 2008, resulting in SQL Compare 7, followed by a UI redesign in SQL Compare 8. By the end of this project in early 2009 I had become the 'go-to' guy for the SQL Compare Engine (I'll explain what that means in a later post), which is used by most of the other tools in the SQL Tools division in one way or another. After that, we decided to expand into Oracle, and I wrote the prototype for what became the engine of Schema Compare for Oracle (SCO). In the latter half of 2009 a full project was started, resulting in the release of SCO v1 in early 2010. Near the end of 2010 I moved to the .NET division, where I joined the team working on SmartAssembly. That's what I continue to work on today. The posts in this series will cover my experience in software development at Red Gate, within the SQL Tools and .NET divisions. Hopefully, you'll find this series an interesting look at what exactly goes into producing the software at Red Gate.

  • Game Changer Appliance for SMBs Powered by Oracle Linux

    - by Zeynep Koch
    In the November 28th CRN article  Review: Thumbs-Up On Oracle Database Appliance  , Edward F. Moltzen mentions that "The Test Center likes this appliance (Oracle Database Appliance) , for the performance and for the strong security offered by the underlying Oracle Linux in the box. It’s more than a solid offering for the SMB space; it’s potentially a game-changer as data and security needs race to keep up with the oncoming generations of technology." The Oracle Database Appliance is a new way to take advantage of the world's most popular database—Oracle Database 11g—in a single, easy-to-deploy and manage system.

  • More info: a "stand-alone" installer for Management Studio Express 2008

    - by AaronBertrand
    Last February, I blogged about something I was initially very happy about: a stand-alone installer for Management Studio Express (SSMSE) 2008 . Now users could allegedly download a much smaller installer, and only install the client tools without having to install an instance of SQL Server Express. While the latter is true, the former remains a pipe dream. Bill Ramos stated in his 2009-02-20 announcement : "We teased out the Tools portion of SQL Server 2008 Express with Tools into it’s own download."...(read more)

  • Packaging Swing apps with integrated JavaFX content

    - by igor
    JavaFX provides a lot of interesting capabilities for developing rich client applications in Java, but what if you are working on an existing Swing application and you want to take advantage of these new features?  Maybe you want to use one or two controls like the LineChart or a MediaView.  Maybe you want to embed a large Scene Graph as an initial step in porting your application to FX.  A hybrid Swing/FX application might just be the answer. Developing a hybrid Swing + JavaFX application is not terribly difficult, but until recently the deployment of hybrid applications has not simple as a "pure" JavaFX application.  The existing tools focused on packaging FX Applications, or Swing applications - they did not account for hybrid applications. But with JavaFX 2.2 the tools include support for this hybrid application use case.  Solution  In JavaFX 2.2 we extended the packaging ant tasks to greatly simplify deploying hybrid applications.  You now use the same deployment approach as you would for pure JavaFX applications.  Just bundle your main application jar with the fx:jar ant task and then generate html/jnlp files using fx:deploy.  The only difference is setting toolkit attribute for the fx:application tag as shown below: <fx:application id="swingFXApp" mainClass="${main.class}" toolkit="swing"/>  The value of ${main.class} in the example above is your application class which has a main method.  It does not need to extend JavaFX Application class. The resulting package provides support for the same set of execution modes as a package for a JavaFX application, although the packages which are created are not identical to the packages created for a pure FX application.  You will see two JNLP files generated in the case of a hybrid application - one for use from Swing applet and another for the webstart launch.  Note that these improvements do not alter the set of features available to Swing applications. The packaging tools just make it easier to use the advanced features of JavaFX in your Swing application. The same limits still apply, for example a Swing application can not use JavaFX Preloaders and code changes are necessary to support HTML splash screens. Why should I use the JavaFX ant tasks for packaging my Swing application?  While using FX packaging tool for a Swing application may seem like a mismatch at face value, there are some really good reasons to use this approach.  The primary justification for our packaging tools is to simplify the creation of your application artifacts, and to reduce manual errors.  Plus, no one should have to write JNLP by hand. Some specific benefits include: Your application jar will include a launcher program.  This improves your standalone launch by: checking for the JavaFX runtime guiding the user through any necessary installations setting the system proxy for Java The ant tasks will generate JNLP and HTML files for your swing app: avoids learning unnecessary details about JNLP, and eliminates the error-prone hand editing of JNLP files simplifies using advanced features like embedding JNLP and signing jars as BLOBs to improve launch performance.you can also embed the signing certificate details to improve the user's experience  allows the use of web page templates to inject the generated code directly into your actual web page instead of being forced to copy/paste the generated code snippets. What about native packing? Absolutely!  The very same ant task can generate a native bundle for a Swing application with JavaFX content.  Try running one of these sample native bundles for the "SwingInterop" FX example: exe and dmg.   I also used another feature on these examples: a click-through license agreement for .exe installers and OS X DMG drag installers. Small Caveat This packaging procedure is optimized around using the JavaFX packaging tools for your entire Swing application.  If you are trying to embed JavaFX content into existing project (with an existing build/packing process) then you may need to experiment in order to find the best way to integrate the JavaFX packaging steps into your existing build procedure. As long as you can use ant in your build process this should be a workable approach. It some cases solution could be less than ideal. For example, you need to use fx:jar to package your main jar file in order to produce a double-clickable jar or a native bundle.  The jar will be created from scratch, but you may already be creating the main jar file with a custom manifest.  This may lead to some redundant steps in your build process.  Hopefully the benefits will outweigh the problems. This is an area of ongoing development for the team, and we will continue to refine and improve both the tools and the process. Please share your experiences and suggestions with us.  You can comment here on the blog or file issues to JIRA. Sample code Here is the full ant code used to package SwingInterop.  You can grab latest JavaFX samples and try it yourself:  <target name="-post-jar"> <taskdef resource="com/sun/javafx/tools/ant/antlib.xml" uri="javafx:com.sun.javafx.tools.ant" classpath="${javafx.tools.ant.jar}"/> <!-- Mark application as Swing-based --> <fx:application id="swingFXApp" mainClass="${main.class}" toolkit="swing"/> <!-- Create doubleclickable jar file with embedded launcher --> <fx:jar destfile="${dist.jar}"> <fileset dir="${build.classes.dir}"/> <fx:application refid="swingFXApp" name="SwingInterop"/> <manifest> <attribute name="Implementation-Vendor" value="${application.vendor}"/> <attribute name="Implementation-Title" value="${application.title}"/> <attribute name="Implementation-Version" value="1.0"/> </manifest> </fx:jar> <!-- sign application jar. Use new self signed certificate --> <delete file="${build.dir}/test.keystore"/> <genkey alias="TestAlias" storepass="xyz123" keystore="${build.dir}/test.keystore" dname="CN=Samples, OU=JavaFX Dev, O=Oracle, C=US"/> <fx:signjar keystore="${build.dir}/test.keystore" alias="TestAlias" storepass="xyz123"> <fileset file="${dist.jar}"/> </fx:signjar> <!-- generate JNLPs, HTML and native bundles --> <fx:deploy width="960" height="720" includeDT="true" nativeBundles="all" outdir="${basedir}/${dist.dir}" embedJNLP="true" outfile="${application.title}"> <fx:application refId="swingFXApp"/> <fx:resources> <fx:fileset dir="${basedir}/${dist.dir}" includes="SwingInterop.jar"/> </fx:resources> <fx:permissions/> <info title="Sample app: ${application.title}" vendor="${application.vendor}"/> </fx:deploy> </target>

  • I'd like to rebuild my web server without web management software; what knowledge, skills, and tools will I require? [closed]

    - by Joe Zeng
    I've been using Webmin for my web server that runs my personal website and a host of other websites for a while now, and I feel like I should be able to manage my web server more directly, because I haven't even touched the Webmin for the past year or so and I feel like maybe it has too much functionality that I have to click through the next time I want to access it or create a new subdomain or database on my site. I want to try something lighter and more wholly manageable, now that I'm more comfortable with using ssh and command-line tools. I've decided that I'm going to try using Django as a framework, but obviously that's only part of the picture. What sort of knowledge will I require?

  • Hudson.. another Continuous Integration tool

    - by Narendra Tiwari
    In my previous posts I discussed about Cruisecontrol.net and its legacy support to .Net development. Hudson  is yet another continuous integration tool. Hudson is also free like CCNet and built in java. - CCNet has its legacy support to .Net applications where as Hudson can be easily configured on both the environments (.Net and Java). - One of the major differences in CCNet and Hudson is the richer GUI of Hudson provide user interactive screens for project configuration where as in CCNet we have to play with a few xml configuration files. Both the tools are capable of providing basic features of continuous integration e.g.:- - Source Control configuration - Code Compilation/Build - Ad hoc plugin tools to be configured along with compilation Support for adhoc tools seems to be bigger with CCNet e.g. There are almost every source control plugin available with CCNet where as Hudson has support for limited source control servers. Basically there is an interseting point to see is that there are 2 major partsof whole CI system one performed by build tool and rest. Build tool takes care of all adhoc plugin tools  so no matter if CI tool does not have plugin for that tool if thet tools provides command line support that can be configured in build tool and that build tool is then configured with CI tool inturn. For example if I have a build script configured in MSBuild and CCNet can be easily switched to Hudson. Here we need not to change anything in build script we just need to configure MSBuild on Hudson and pass the path of script file and thats it... all is same.

  • Windows 7 File Associations .mov

    - by Paul Mung
    I created a new windows 7 SP1 base image. Everything is all fine and dandy with that. So i am now installing standard applications I would like Quicktime to manage .mov files. The only problem is WMP (Windows Media Player) won't give up the association to .mov files. It's driving me crazy... i've been reading threads on how to fix file associations. I would like to do it via registry, powershell or cmdline. I cannot use GPO I've tried the following: assoc .mov=QuickTime.mov ftype QuickTime.mov="%ProgramFiles(x86)\QuickTime\QuickTimePlayer.exe" Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\UserChoice" /v Progid /d QuickTime.mov /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithList" /v a /d QuickTimePlayer.exe /f Reg add "HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithList" /v b /d wmplayer.exe /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithList" /v MRUList /d ab /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithProgids" /v Quicktime.mov /t REG_NONE /d 0000 /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithProgids" /v WMP11.AssocFile.MOV /t REG_NONE /d 0000 /f

  • Visual Studio 2010 RC &ndash; Silverlight 4 and WCF RIA Services Development - Updates from MIX Anno

    - by Harish Ranganathan
    MIX is happening and there is a lot of excitement around the various releases such as the Windows Phone 7 Developer Preview, IE9 Platform Preview and few other announcements that have been made.  Clearly, the Windows Phone 7 Developer Preview has generated the maximum interest and opened a plethora of opportunities for .NET Developers.  It also takes the mobile development to a new generation and doesn’t force developers to learn different programming language. Along with this, few other releases have been out.  The most anticipated Silverlight 4 RC is out and its corresponding templates are also out there for you to download.  Once VS 2010 RC was released, it was much of a disappointment that it doesn’t support SL4 development as well as the SL4 Business Application Development (a.k.a. WCF RIA Services).   There were few workarounds though nothing concrete.  Earlier I had written about how the WCF RIA Services Preview does work with ASP.NET Development using VS 2010 RC. However, with the release of SL4 RC and the corresponding tooling updates, one can develop for both SL4 as well as SL4 + WCF RIA Services using VS 2010 RC.  This is kind of important and keeps the continuum going until VS 2010 RTMs.  So, the purpose of this post is to quickly give the updates and links to install the relevant tools. Silverlight 4 RC Runtime Windows Runtime or the Mac Runtime Silverlight 4 RC Developer Tools for Visual Studio 2010 RC Silverlight 4 Tools for Visual Studio 2010 (this would install the Runtime as well automatically) Expression Blend 4 Beta Expression Blend 4 Beta If you install the SL4 RC Developer Tools, it also installs the WCF RIA Services Preview automatically.  You just need to install the WCF RIA Services Toolkit that can be downloaded from Install the WCF RIA Services Toolkit Of course you can also just install the WCF RIA Services for VS 2010 RC separately (without SL4 Tools) from here Kindly note, all the above mentioned links are with respect to Visual Studio 2010 RC edition.  If you are developing with VS 2008, then you can just target SL3 (as I write this, there seems to be no official support for developing SL4 with VS 2008) and the related tools can be downloaded from http://www.silverlight.net/getstarted/ Basically you need to download SL 3 Runtime, SDK, Expression Blend 3 and the Silverlight Toolkit.  All the links for the download are available in the above mentioned page. Also, a version of WCF RIA Services that is supported in VS 2008 is available for download at WCF RIA Services Beta for VS 2008 I know there are far too many things to keep in mind.  So, I put a flowchart that could help with depicting it pictorial.  Note that this is just my own imagination and doesn’t cover all scenarios.  for example, if you are neither developing for Webform, Silverlight, you end up nowhere whereas in actual scenario you may want to develop Desktop, Services, Console, Game and what not.  So, keep in mind this is just Web. Cheers !!!

  • Online Media Daily: Oracle Takes Social Marketing Seriously

    - by Richard Lefebvre
    In the article published on Nov 12, 2012 and titled "Oracle Integrates Social Marketing Into Enterprise To Gain Marketing Revs," Online Media Daily explores Oracle's approach to social marketing. The publication says that Oracle is focused on showing marketers how to integrate social data into corporate business processes and how to "socialize" the corporate world. The article goes on to state:"Enterprise software companies like Oracle, SAP, IBM, Salesforce and Microsoft have been slowly building up an expertise in social marketing to integrate the data into traditional enterprise resource planning, and customer relationship management tools into social marketing tools.   Enterprise software companies like Oracle, SAP, IBM, Salesforce and Microsoft have been slowly building up an expertise in social marketing to integrate the data into traditional enterprise resource planning, and customer relationship management tools into social marketing tools.    Read more: http://www.mediapost.com/publications/article/187096/oracle-integrates-social-marketing-into-enterprise.html#ixzz2CPMZ1w3D Meg Bear, VP of cloud social platform at Oracle, sees the integration with ERP systems as a differentiator for the company. Oracle Social Relationship Management launched last month. It integrates social data into traditional enterprise applications like Oracle Fusion Marketing, Oracle Fusion Sales Catalog, Oracle ATG Web Commerce and Oracle ERP." The post goes on to quote a Forrester analyst stating the following:""There's room for any process-driven application to run more efficiently, especially if they're socially enabled," said Rob Koplowitz, VP and principal analyst at Forrester Research. "It takes the human part of the process not generally captured today to provide better access to content, information and collective actions." Koplowitz said several acquisitions support Oracle's long-term vision: to layer social on top of other enterprise apps, like its ERP platform." With many great acquisitions under our belt and organically grown social tools, the market recognizes that Oracle is poised to seize the moment in socially enabled business apps.

  • Developing an internet-enabled application as a Kiosk on Windows 7

    - by maple_shaft
    I am finalizing development of a desktop Java application that communicates with an outside web server, and now I need to start seriously considering deployment. This application will run on a large touchscreen all-in-one workstation running Windows 7. It will be located in a public-area and thus must be LOCKED-DOWN Hanibal Lecter style. Early in the project nobody really concerned themselves with this fact just assuming that we can buy some magical software for Windows 7 that will automatically take care of all this, however I am finding now that this looks to be a LOT more complicated than my manager ever thought. I need to: - Lock down the standard hot-keys (ALT+TAB, ALT+CTRL+DEL, etc...) Prevent the user from opening ANY programs other than the kiosk application and its spawned executables Prevent the user from closing the application Start the kiosk application on startup (this can be done without kiosk software) Auto-login to Windows on reboot (Windows Updates, power failure, bratty kid pressing the power button, etc...) Administrator passcode escape sequence for routine maintenance by desktop support professionals. To my dismay I am having a really hard time finding software that contains the whole package and am finding numerous swaths of competing information on the best way to do this. I am not necessarily looking for free or open source software and am willing to pay for software that can help me achieve this. Have any of you ever wrote kiosk software before and if so what approaches have you taken to do this?

  • VMWare Fusion Folder Sharing Not Working with Server

    - by Dave Long
    I have a Ubuntu Server running in VMWare Fusion 3.1.2 on my MacBook Pro for Java development and all my projects sit on my Mac in ~/Workspace/ColdFusion. I had ColdFusion/ shared with my VM through the VMWare tools, and it was working perfectly up until friday when the folder sharing just stopped. No updates on either mac or linux besides an iTunes update. I tried uninstalling the VMWare tools and reinstalling them but I get an error at the end of the install. It appears that when I reinstall the tools there are files left over from the old installation. Is there a way to force the unsinstall script to completely uninstall and remove all files for the VMWare-Tools? I know the shared folder used to mount at /mnt/hgfs/ColdFusion.

  • How to get multiple open-source projects to use a standard way of doing something.

    - by Marco
    Problem In the last couple weeks, I've used 3 different "repository" tools (listed in alphabetical order): gradle ivy maven I'm calling them "repository" tools because I've also used sbt -- which fortunately uses ivy to manage it's cache or local repository. Each of these tools will create it's own repository. The defaults are: ~/.m2/repository for maven ~/.gradle/cache ~/.ivy2/cache Why can't they all use the same cache? Goal I'd like to change the world so that all three build tools could use the same cache. I'm looking for advice about issues I'm likely to run into and smart ways to get around them. By "use the same cache", I do not mean "retrieve from another build tool's cache". I mean "retrieve from and store in another build tool's cache". While I could go ahead and submit issues to the three projects, I know from experience (as a developer on an open source project), that if you want something done, you're best off getting it done yourself. Also, it seems like I need to get all 3 communities on board to some degree. What is the recommended approach for getting this kind of thing done? How do I approach the different communities? Do I work on patches for the 3 different projects, or would it be better off to create my own "interface" project that deals with these issues and have the 3 tools interface with that? Is this a standards question that I need to address on that front? Lastly, if I'm missing something and this is possible (in an globally configurable fashion), then please let me know.

  • Data migration - dangerous or essential?

    - by MRalwasser
    The software development department of my company is facing with the problem that data migrations are considered as potentially dangerous, especially for my managers. The background is that our customers are using a large amount of data with poor quality. The reasons for this is only partially related to our software quality, but rather to the history of the data: Most of them have been migrated from predecessor systems, some bugs caused (mostly business) inconsistencies in the data records or misentries by accident on the customer's side (which our software allowed by error). The most important counter-arguments from my managers are that faulty data may turn into even worse data, the data troubles may awake some managers at the customer and some processes on the customer's side may not work anymore because their processes somewhat adapted to our system. Personally, I consider data migrations as an integral part of the software development and that data migration can been seen to data what refactoring is to code. I think that data migration is an essential for creating software that evolves. Without it, we would have to create painful software which somewhat works around a bad data structure. I am asking you: What are your thoughts to data migration, especially for the real life cases and not only from a developer's perspecticve? Do you have any arguments against my managers opinions? How does your company deal with data migrations and the difficulties caused by them? Any other interesting thoughts which belongs to this topics?
