  • Application Demos in UPK

    - by [email protected]
    Over the years, User Productivity Kit has expanded to include solutions to many project challenges. As of UPK 3.6.1, solutions are provided for pre and post application go-live learning, application testing, system documentation, presentation output, and more. New in UPK 3.6.1 are additional features that can be used effectively for application demo purposes. This can come in handy when you need to do a demo but don't want to show or can't show the live application. Maybe you're doing a presentation for a group of project stakeholders and want to focus on the business workflow implemented by the application rather than the mechanics of using it. Or possibly, you need to show the application but you're disconnected from any network preventing you from running the live application. In any of these cases, a presentation aid that represents the live application is what's needed. Previous versions of the UPK topic player would allow you to do this but would always show those UPK user interface elements that help a user learn the application. When you're presenting the narrative live, the UPK bubbles can be a distraction. UPK 3.6.1 provides some new features that allow you to control whether the bubbles display. There are two ways to hide bubbles in a topic. The first is a topic property that allows you to control bubbles across the entire topic. There are 3 settings for the Show Bubbles topic property. The default setting is Use frame settings which allows you to control whether bubbles display on a frame by frame basis. When you choose Always, the bubbles will always display regardless of the frame setting. The final choice is Never. Choosing Never will hide every bubble in your topic with one setting change. As with Always, choosing Never will ignore the frame setting. The second way to control the bubbles is at the frame level. First ensure that the topic's Show Bubbles property is set to Use frame settings. Navigate to the frame on which you want to turn off the bubble and click the Display bubble for this frame button to turn off the bubble. When you play the topic, the bubble will no longer be displayed. Depending on your needs, you might also use another longstanding UPK feature that allows you to control whether the action area displays on a frame. Just click the Action area on/off button to toggle its display. I've found the frame properties to be useful beyond creating presentation aids. When creating "See It!" only topics for more advanced users, I may hide the bubbles on some of the more straightforward frames. For example, if I have a form where one needs to fill out an address, I may display the first bubble in the sequence and explain what the subsequent steps are doing. I then hide bubbles on the remaining frames which are the more mechanical steps of entering the address. We'd like to hear your thoughts on this new UPK feature. Use the comments below to tell us how you've used it. John Zaums Senior Director, Product Development Oracle User Productivity Kit

  • The Beginner’s Guide to Greasemonkey User Scripts in Firefox

    - by Asian Angel
    Everybody knows that Firefox has add-ons for virtually everything, but if you don’t want to bloat your installation you’ve always got the option of Greasemonkey scripts instead. Here’s a quick primer on how to use them. Getting Started with User Scripts Once you have Greasemonkey installed, managing the extension is really easy. Left click on the status bar icon to turn the extension on/off and right click to access the context menu shown here. Whether you use the Options button in the Add-ons Manager Window or the context menu shown above, both will bring up the Manage User Scripts dialog. At the moment you have a nice clean slate to work with… time to get some scripts added in. The majority of user scripts can be found at two different sites, the first being appropriately named userscripts.org, and you can either browse by tag or search for a script. As you can see here your search for a particular type of script can be quickly narrowed down based on category. There is definitely a lot to choose from. For our example we focused on the “textarea” tag. There were 62 scripts available but we quickly found what we were looking for on the first page. Installing, Managing, & Using Your Scripts When you find a script that you want to install visit the script’s homepage and click on the “Install” button. Note: Link for this script provided below. Once you have clicked on the Install button, Greasemonkey will open up the following installation window. You will be able to view: A summary of what the script does A list of websites that the script is supposed to function on (our example is set for all) View the script source if desired Make a final decision on whether to install the script or cancel the process Right-clicking on our status bar icon shows our new script listed and active. Reopening the Manage User Scripts window shows: Our new script listed in the column on the left The websites/pages included An option to disable the script (can also be done in the context menu) The ability to edit the script The ability to uninstall the script If you choose to edit the script you will be asked to browse for and select a default text editor of your choice (first time only). Once you have selected a text editor you can make any changes desired to the script. We decided to test our new user script on the site. Going to the comment box at the bottom we could easily resize the window as desired. The Comment box definitely got a lot bigger. Conclusion If you prefer to keep the number of extensions to a minimum in your Firefox installation then Greasemonkey and the Userscripts website can easily provide that extra functionality without the bloat. For added auto website script detection goodness see our article on Greasefire. Note: See our article here for specialized How-To Geek User Style Scripts that can be added to Greasemonkey.

  • What are developer's problems with helpful error messages?

    - by Moo-Juice
    It continue to astounds me that, in this day and age, products that have years of use under their belt, built by teams of professionals, still to this day - fail to provide helpful error messages to the user. In some cases, the addition of just a little piece of extra information could save a user hours of trouble. A program that generates an error, generated it for a reason. It has everything at its disposal to inform the user as much as it can, why something failed. And yet it seems that providing information to aid the user is a low-priority. I think this is a huge failing. One example is from SQL Server. When you try and restore a database that is in use, it quite rightly won't let you. SQL Server knows what processes and applications are accessing it. Why can't it include information about the process(es) that are using the database? I know not everyone passes an Applicatio_Name attribute on their connection string, but even a hint about the machine in question could be helpful. Another candidate, also SQL Server (and mySQL) is the lovely string or binary data would be truncated error message and equivalents. A lot of the time, a simple perusal of the SQL statement that was generated and the table shows which column is the culprit. This isn't always the case, and if the database engine picked up on the error, why can't it save us that time and just tells us which damned column it was? On this example, you could argue that there may be a performance hit to checking it and that this would impede the writer. Fine, I'll buy that. How about, once the database engine knows there is an error, it does a quick comparison after-the-fact, between values that were going to be stored, versus the column lengths. Then display that to the user. ASP.NET's horrid Table Adapters are also guilty. Queries can be executed and one can be given an error message saying that a constraint somewhere is being violated. Thanks for that. Time to compare my data model against the database, because the developers are too lazy to provide even a row number, or example data. (For the record, I'd never use this data-access method by choice, it's just a project I have inherited!). Whenever I throw an exception from my C# or C++ code, I provide everything I have at hand to the user. The decision has been made to throw it, so the more information I can give, the better. Why did my function throw an exception? What was passed in, and what was expected? It takes me just a little longer to put something meaningful in the body of an exception message. Hell, it does nothing but help me whilst I develop, because I know my code throws things that are meaningful. One could argue that complicated exception messages should not be displayed to the user. Whilst I disagree with that, it is an argument that can easily be appeased by having a different level of verbosity depending on your build. Even then, the users of ASP.NET and SQL Server are not your typical users, and would prefer something full of verbosity and yummy information because they can track down their problems faster. Why to developers think it is okay, in this day and age, to provide the bare minimum amount of information when an error occurs? It's 2011 guys, come on.

  • Build Explorer version 1.1 for Visual Studio Team Explorer is released

    - by terje
    Our free extension to Visual Studio , the folder based Build Explorer Version 1.1 has now been released, and uploaded to the Visual Studio Gallery and Codeplex. We have collected up a few changes and some bugs, as follows: Changes: Queue Default Builds can now be optionally fully enabled, fully disabled or enabled just for leaf nodes (=disabled for folders).  If you got a large number of builds it was pretty scary to be able to launch all of them with just one click.  However, it is nice to avoid having the dialog box up when you want to just run off a single build.  That’s the reasoning between the 3rd choice here. Auto fill-in of the builds at start up and refresh  This was a request that came up a lot, and which was also irritating to us.  When the Team Project is opened, the Build explorer will start by itself and fill up it’s tree. So you don’t need to click the node anymore. There was also quite a bit of flashing when the tree filled up, this has been reduced to just a single top level fill before it collapses the node. The speed of the buildup of the tree has also been increased. The “All Build Definitions” node is now shown on top of the list Login box appeared in certain cross domain situations. This was a fix for the TF30063 authentication problem we had in the beginning.  Hopefully the new code has that fixed properly so that both the login box and the TF30063 are gone forever.  Our testing so far seems to indicate it works.  If anyone gets a real problem here there are two workarounds: 1) Turn off the auto refresh to reduce the issue. If this doesn’t fix it, then 2) please reinstall the former version (go to the codeplex download site if you don’t have it anymore)  Write a comment to this blog post with a description of what happens, and I will send a temporary fix asap. Bug fixes: The folder name matching was case sensitive, so “Application.CI” and “application.CI” created two different folders.  View all builds not shown for leaf odes, and view builds didn’t work in all cases.  There was some inconsistencies here which have been fixed. Partly fixed:  The context menu to queue a new build for disabled builds should be removed, but that was a difficult one, and is still on the list, but the command will not do anything for a disabled build. Using the Queue Default Builds on a folder, and if it had some disabled builds below an error box appeared and ruined the whole experience. As a result of these fixes there has been introduced some new options, as shown below:   The two first settings, the Separator symbol and the options for how to handle Queuing of default builds are set per Team Project, and is stored in the TFS source control under the BuildProcessTemplates folder, with the name Inmeta.VisualStudio.BuildExplorer.Settings.xml The next two settings need some explanations.  They handle the behavior for the auto update of the build folders.  First, these are stored in the local registry per user, at the key HKEY_CURRENT_USER/Software\Inmeta\BuildExplorer. The first option Use Timed Refresh at Startup, if turned off, you will need to click the node as it is done in Version 1.0.  The second option is a timed value, the time after the Build explorer node is created and until the scanning of the Build folders start.  It is assumed that this is enough, and the tests so far indicates this.  If you have very many builds and you see that the explorer don’t get them all, try to increase this value, and of course, notify me of your case, either here or on the Visual Gallery site.

  • BizTalk 2009 - BizTalk Benchmark Wizard: Installation

    - by StuartBrierley
    As previously detailed, I have completed a single server installation of BizTalk Server 2009 standard on my development laptop; a MacBook Pro Core2Duo running at 2.16Ghz with 2Gb of RAM.  Following this I also posted on my use of the BizTalk Server Best Practices Anaylser and how to configure the BizTalk SQL Server Jobs.  All of which means that I should have some confidence that I have a decent working BizTalk Server 2009 environment, Next I thought that it would be a good idea to try and get some idea of how this setup performs by carrying out some baseline tests that can then be replicated on the test and live servers. The aim of this would be to allow confident predictions to be made of how any solutions developed on a single "server" installation may be expected to perform when deployed to these multi-server BizTalk Server 2009 standard installations. The BizTalk Benchmark Wizard would seem to be the perfect tool for the job. The BizTalk Benchmark Wizard is a ultility that can be used to gain some validation of a BizTalk installation, giving a level of guidance on whether it is performing as might be expected. This utility should be used after BizTalk Server has been installed and before any solutions are deployed to the environment.  This will ensure that you are getting consistent and clean results from the BizTalk Benchmark Wizard. The BizTalk Benchmark Wizard applies load to the BizTalk Server environment under a choice of specific scenarios. During these scenarios performance counter information is collected and assessed against statistics that are appropriate to the BizTalk Server environment: "The executed scenarios may or may not be relative to any realistic scenario, and is only intended for testing. The BizTalk Benchmark Wizard has been developed in relation to the BizTalk Server 2009 Scale Out Testing Study. More information about the study can be found here: http://msdn.microsoft.com/en-us/library/ee377068(BTS.10).aspx" After downloading and installing the wizard you will need set up the Hosts, Instances and Adapter handlers.  This is done by running a script file using the “cscript” detailed below.  To do this you will need to open a command prompt window and navigate to the script folder; assuming the default installation location this would be C:\Program Files\Blogical\BizTalk Benchmark Wizard\Artefacts\BizTalk. In this folder you should find an InstallHosts.vbs file which can be executed using the following parameters: NTGroupName - The name of the Windows NT group. UserName – The name of the user account running the service instances. Password – The password of the user account running the service instances. Receive Host – The name of the server where you want to run the receive host instance.  Send Host - The name of the server where you want to run the sen host instance. Processing Host - The name of the server where you want to run the process host instance. By default the script is set up for 64 bit hosts, so if you are running in 32 bit environment make sure that you change the following line in the script before continuing: from:   objHS.IsHost32BitOnly = False to:    objHS.IsHost32BitOnly = True If you have a single box installation, your script command might look like this: cscript InstallHosts.vbs "BizTalk Application Users" “\MyUser” “MyPassword” “BtsServer1” “BtsServer1” “BtsServer1” If you have a multi server installation, your script command might look like this: cscript InstallHosts.vbs "MyDomain\BizTalk Application Users" “MyDomain\MyUser” “MyPassword” “BtsServer1” “BtsServer2” “BtsServer2” Running this script will create: Three hosts (BBW_RxHost, BBW_TxHost and BBW_PxHost) Three host instances One send and one receive adapter handler for the WCF NetTcp adapter. You will then need to import the BizTalk MSI via the BizTalk Administration Console.  Open the BizTalk Administration Console, point to the “Applications” node and import the BizTalk Benchmark Wizard.msi found in the same folder as the script above. This will create a “BizTalk Benchmark Wizard” application along with all ports and orchestrations needed. To finish the installation you will need to run the BizTalk Benchmark Wizard.msi on all BizTalk servers to add the assemblies to the Global Assembly Cache (GAC). Next I will look at running the BizTalk Benchmark Wizard.

  • If You Could Cut Your Meeting Times in ½ Would You?

    - by [email protected]
    By Brian Dayton on April 22, 2010 2:02 PM I know it sounds like a big promise. And what I'm thinking about may not cut a :60 minute meeting into :30 minutes, but it could make meetings and interactions up to 2X more productive. How? Social Media for the Enterprise, Not Social Media In the Enterprise Bear with me. I'm not talking about whether or not workers should or shouldn't have access to Facebook on corporate networks. That topic has been discussed @ length. I'm also not talking about the direct benefits of Social Networking tools like Presence (the ability to see someone online and ask a question in real-time), blogs, RSS feeds or external tools like Twitter. The Un-Measurable Benefits Would you do something that you believe will have a positive effect--but can't be measured? It's impossible to quantify the effectiveness of a meeting. However, what I am talking about would be more of a byproduct of all of the social networking tools above. Here's the hypothesis: As I've gotten more and more busy with work, family, travel and kids--and the same has happened to my friends and family--I'm less and less connected. But by introducing Facebook to my life I've not only made connections with longtime friends whom I haven't spoken to in years--but I've increased the pace and quality of interactions, on and offline, with close friends who I see and speak to every week. In some cases it even enhances the connections and interactions with those I see or speak to every day. The same holds true in an organization. Especially a larger one with highly matrixed organizational structures. You work with people on a project, new people come in with each different project and a disproportionate amount of time is spent getting oriented and staying current. Going back to the initial value proposition--making meetings shorter/more effective--a large amount of time is spent: - At Project Kick-off: Meeting and understanding team member's histories, goals & roles - Ongoing: Summarizing events since the last meeting or update email In my personal, Facebook life today I know that: - My best friend from college - has been stranded in India for 5 days because of the volcano in Iceland and is now only 250 miles from home - One of my co-workers started conference calls at 6:30 this morning - My wife wasn't terribly pleased with my painting skills in our new bathroom (disclosure: she told me this face to face too) Strengthening Weak Links A recent article in CIO Magazine, Three Dangerous Social Media Misconceptions (Kristen Burnham, March 12, 2010) calls out the #1 misconception as follows: 1. "Face-to-face relationships are far more valuable than virtual ones." While some level of physical interaction will always add value to relationships, Gartner says that come 2020, most relationships and teams will be based on "weak links"--that is, you may not have personally met a contact, but you'll know of or may have interacted with him via social sites like Facebook, LinkedIn and Twitter. The sooner your enterprise adopts these tools, the sooner your employees will learn them, and the sooner you'll begin to cultivate these relationships-of-the-future. I personally believe that it's not an either/or choice between face-to-face and virtual interactions. In fact, I'll be as bold as saying it doesn't matter. I can point to two extremely valuable work relationships that I've had over the past 5 years: - I shared an office with one of them - I met the other person, face-to-face, only once Both relationships were very productive. The dynamics were similar. The communication tactics differed immensely. What does matter is the quality, frequency and relevance of interactions. Still sound like too much? An over-promise? Stay tuned for my next post The Gap Between Facebook and LinkedIn. I'll also connect some of the dots with where Oracle Applications and technologies are headed.

  • Making a Job Change That's Easy Why Not Try a Career Change

    - by david.talamelli
    A few nights ago I received a comment on one of our blog posts that reminded me of a statistic that I heard a while back. The statistic reflected the change in our views towards work and showed how while people in past generations would stay in one role for their working career - now with so much choice people not only change jobs often but also change careers 4-5 times in their working life. To differentiate between a job change and a career change: when I say job change this could be an IT Sales person moving from one IT Sales role to another IT Sales role. A Career change for example would be that same IT Sales person moving from IT Sales to something outside the scope of their industry - maybe to something like an Engineer or Scuba Dive Instructor. The reason for Career changes can be as varied as the people who make them. Someone's motivation could be to pursue a passion or maybe there is a change in their personal circumstances forcing the change or it could be any other number of reasons. I think it takes courage to make a Career change - it can be easy to stay in your comfort zone and do what you know, but to really push yourself sometimes you need to try something new, it is a matter of making that career transition as smooth as possible for yourself. The comment that was posted is here below (thanks Dean for the kind words they are appreciated). Hi David, I just wanted to let you know that I work for a company called Milestone Search in Melbourne, Victoria Australia. (www.mstone.com.au) We subscribe to your feed on a daily basis and find your blogs both interesting and insightful. Not to mention extremely entertaining. I wonder if you have missed out on getting in journalism as this seems to be something you'd be great at ?: ) Anyways back to my point about changing careers. This could be anything from going from I.T. to Journalism, Engineering to Teaching or any combination of career you can think of. I don't think there ever has been a time where we have had so many opportunities to do so many different things in our working life. While this idea sounds great in theory, putting it into practice would be much harder to do I think. First, in an increasingly competitive job market, employers tend to look for specialists in their field. You may want to make a change but your options may be limited by the number of employers willing to take a chance on someone new to an industry that will likely require a significant investment in time to get brought up to speed. Also, using myself as an example if I was given the opportunity to move into Journalism/Communication/Marketing career from my career as an IT Recruiter - realistically I would have to take a significant pay cut to make this change as my current salary reflects the expertise I have in my current career. I would not immediately be up to speed moving into a new career and would not be able to justify a similar salary. Yes there are transferable skills in any career change, but even though you may have transferable skills you must realise that you will also have a large amount of learning to do which would take time. These are two initial hurdles that I immediately think of, there may be more but nothing is insurmountable. If you work out what you want to do with your working career whatever that may be, you then need to just need to work out the steps to get to your end goal. This is where utilising the power of your networks and using Social Media can come in handy. If you are interested in working somewhere why not proactively take the opportunity to research the industry or company - find out who it is you need to speak to and get in touch with them. We spend so much time working, we should enjoy the work we do and not be afraid to try new things. Waiting for your dream job to fall into your lap or be handed to you on a silver platter is not likely going to happen, so if there is something you do want to do, work out a plan to make it happen and chase after it.

  • Getting a Database into Source Control

    - by Grant Fritchey
    For any number of reasons, from simple auditing, to change tracking, to automated deployment, to integration with application development processes, you’re going to want to place your database into source control. Using Red Gate SQL Source Control this process is extremely simple. SQL Source Control works within your SQL Server Management Studio (SSMS) interface.  This means you can work with your databases in any way that you’re used to working with them. If you prefer scripts to using the GUI, not a problem. If you prefer using the GUI to having to learn T-SQL, again, that’s fine. After installing SQL Source Control, this is what you’ll see when you open SSMS:   SQL Source Control is now a direct piece of the SSMS environment. The key point initially is that I currently don’t have a database selected. You can even see that in the SQL Source Control window where it shows, in red, “No database selected – select a database in Object Explorer.” If I expand my Databases list in the Object Explorer, you’ll be able to immediately see which databases have been integrated with source control and which have not. There are visible differences between the databases as you can see here:   To add a database to source control, I first have to select it. For this example, I’m going to add the AdventureWorks2012 database to an instance of the SVN source control software (I’m using uberSVN). When I click on the AdventureWorks2012 database, the SQL Source Control screen changes:   I’m going to need to click on the “Link database to source control” text which will open up a window for connecting this database to the source control system of my choice.  You can pick from the default source control systems on the left, or define one of your own. I also have to provide the connection string for the location within the source control system where I’ll be storing my database code. I set these up in advance. You’ll need two. One for the main set of scripts and one for special scripts called Migrations that deal with different kinds of changes between versions of the code. Migrations help you solve problems like having to create or modify data in columns as part of a structural change. I’ll talk more about them another day. Finally, I have to determine if this is an isolated environment that I’m going to be the only one use, a dedicated database. Or, if I’m sharing the database in a shared environment with other developers, a shared database.  The main difference is, under a dedicated database, I will need to regularly get any changes that other developers have made from source control and integrate it into my database. While, under a shared database, all changes for all developers are made at the same time, which means you could commit other peoples work without proper testing. It all depends on the type of environment you work within. But, when it’s all set, it will look like this: SQL Source Control will compare the results between the empty folders in source control and the database, AdventureWorks2012. You’ll get a report showing exactly the list of differences and you can choose which ones will get checked into source control. Each of the database objects is scripted individually. You’ll be able to modify them later in the same way. Here’s the list of differences for my new database:   You can select/deselect all the objects or each object individually. You also get a report showing the differences between what’s in the database and what’s in source control. If there was already a database in source control, you’d only see changes to database objects rather than every single object. You can see that the database objects can be sorted by name, by type, or other choices. I’m going to add a comment such as “Initial creation of database in source control.” And then click on the Commit button which will put all the objects in my database into the source control system. That’s all it takes to get the objects into source control initially. Now is when things can get fun with breaking changes to code, automated deployments, unit testing and all the rest.

  • Tool to convert blogger.com content to dasBlog

    - by Daniel Moth
    Due to blogger.com dropping FTP support, I've had to move my blog. If you are in a similar situation, this post will help you by showing you the necessary steps to take. Goals No loss on blog posts, comments AND all existing permalinks continue to work (redirect to the correct place). Steps Download the XML files corresponding to your blogger.com content and store them in a folder. Install and configure dasBlog on your local machine. Configure your web.config file (will need updating once you run step 4). Use the tool I describe further down to generate the content and place it at the right place. Test your site locally. Once you are happy, repeat step 2 on your hosting provider of choice. Remember to copy up your dasBlog theme folder if you created one. Copy up the local web.config file and the XML dasBlog content files generated by the tool of step 4. Test your site on the server. Once you are happy, go live (following instructions from your hoster). In my case, I gave the nameservers from my new hoster to my existing domain registrar and they made the switch. Tool (code) At step 4 above I referred to a tool. That is an overstatement, it is simply one 450-line C#code file that you can download here: BloggerToDasBlog.cs. I used this from a .NET 2.0 console app (and I run it under the Visual Studio debugger, i.e. F5) like this: Program.cs. The console app referenced the dasBlog 2.3 ASP.NET Blogging Engine i.e. the newtelligence.DasBlog.Runtime.dll assembly. Let me describe what the code does: Input: A path to a folder where the XML files from the old blogger.com blog reside. It can deal with both types of XML file. A full file path to a file where it creates XML redirect input (as required by the rewriteMap mentioned here). The blog URL. The author's email. The blog author name. A path to an empty folder where the new XML dasBlog content files will get created. The subfolder name used after the domain name in the URL. The 3 reg ex patterns to use. You can use the same as mine, but will need to tweak the monthly_archive rule. Again, to see what values I passed for all the above, see my Program.cs file. Output: It creates dasBlog XML files in the folder specified. It creates those by parsing the old blogger.com XML files that reside in the folder specified. After that is generated, copy it to the "Content" folder under your dasBlog installation. It creates an XML file with a single ignorable root element and a bunch of inner XML elements. You can copy paste these in the web.config file as discussed in this post. Other notes: For each blog post, it detects outgoing links to itself (i.e. to the same blog), and rewrites those to point to the new URLs. So internal links do not rely on the web.config redirects. It deals with duplicate post titles; it does not deal with triplicates and higher. Removes all references to blogger.com (e.g. references to [email protected], the injected hidden footer for statistics that each blog post has and others – see the code). It creates a lot of diagnostic output (in the Output window) and indeed the documentation for the code is in the Debug.WriteLine statements ;) This is not code I will maintain or support – it was a throwaway one-use project that I am sharing here as a starting point for anyone finding themselves in the same boat that I was. Enjoy "as is". Comments about this post welcome at the original blog.

  • Databases in Source Control

    - by Grant Fritchey
    I’ve been working as a database professional for quite a long time. But originally, I was a developer. And I loved being a developer. There was this constant feedback loop of a job well done, your code compiled and it ran. Every time this happened successfully, you’d check it into source control. These days you have to add another step; the code passed all the tests, unit, line, regression, qa, whatever, then into source control it goes. As a matter of fact, when I first made the jump from developer to DBA/database developer/database professional, source control was the one thing I couldn’t believe was missing from the DBA toolbox. Come to find out, source control was only the beginning of what was missing from your standard DBAs set of skills. Don’t get me wrong. I’m not disrespecting the DBA. They’re focused where they should be, on your production data. But there has to be a method for developing applications that include databases and the database side of that development and deployment process has long been lacking. This lack of development and deployment methodologies is a part of what has given rise to some of the wackier implementations of Object Relational Mapping tools, the NoSQL movement, and some of the other foul cursing that is directed towards databases, DBAs, and database development by application developers. Some of that is well earned. A lot isn’t. But it is a fact that database professionals, in general, do not have as sophisticated a model for managing development and deployment as application developers do. We could charge out and start trying to come up with our own standards and methods. I’m sure people have done exactly that. However, I’m lazy, and not terribly bright. Rather than try to invent a whole new process, I’m going to look to my developer roots and choose instead to emulate the developers. They’re sitting over there across the hall from me working with SCRUM/Agile/Waterfall/Object Driven/Feature Driven/Test Driven development processes that they’ve been polishing for years. What if I just started working on database development the same way they work on code development? Win! Ah, but now I have to have a mechanism for treating my database like application code. First, I need a method for getting it into source control. That’s where Red Gate’s SQL Source Control comes into the picture. SQL Source Control works within SQL Server Management Studio to connect your database objects up to the source control system of your choice. Right out of the box SQL Source Control can link to TFS, SVN or Vault. With a little work you can connect it to Git or just about any other source control system. With the ability to get my database into source control, a lot of possibilities for more direct integration with the application development teams open up.

  • My Mother Bought a Droid

    - by Ben Griswold
    I converted to iPhone two years ago when I left my former employer and my Blackberry behind. The truth is I half-heartedly purchased my iPhone. It was a great looking device, but as far as I was concerned, it was a mere toy compared to my Blackberry.  I remember hiding the toy in my briefcase when attending business meetings because I didn’t consider it to be professional enough.  I’ve since owned all three generations of the iPhone and, well, iPhone seems to have caught on. I still miss the click of the Blackberry keyboard and the blinking red light letting me know that someone/something requires my attention, but I’m officially an iPhone fanboy now.  My mom called last weekend and asked if she should buy an iPhone. I talked her ear off about everything I love about iPhone. I went on for about twenty minutes. I couldn’t help myself. I mentioned everything from my podcast subscriptions to the application which manages my workouts.  I went as far as to say that someday all smart phones will be referred to as iPhones just like all tissues are referred to as Kleenex and all sodas are referred to as Cokes.  I was really on a roll and then I stopped. I had to…the call dropped.  There I was, strategically standing in the far corner of my backyard where I get the most reliable AT&T reception and the call drops in middle of my iPhone pitch.  Folks, I don’t care how good a salesperson you are, it’s tough to recover from a situation like this.   I dialed my mom back and jokingly asked if she was planning to make calls with her new phone. I explained that AT&T is bound to provide better service eventually but I’m not sure she should wait. After all, I have troubles with the network in San Diego and I can only image how bad it would be for her in Western Massachusetts. Mom called back a few days later exclaiming, “I bought a Droid! I love this phone! I haven’t done anything with it but make phone calls, but I love it.”  I had to laugh.  My mom made the right call (pun intended.)  The iPhone is an amazing device, but owners are constantly reminded that its core function (it’s a phone, remember?) is subpar.  If you love gadgets, you’re probably enthralled by iPhone’s many bells and whistles and, relatively speaking, the terrible phone service might not amount to much.  (Maybe it amounts to a rant on your blog.) The overall iPhone offering is so attractive that consumers are willing to wait for AT&T to straighten up their act or wait until Apple grants a choice of carriers.  But I don’t see either of these remedies coming soon. In the interim, I’m willing to take my iPhone for what it is and just continue to enjoy my favorite features while pretending that poor coverage isn’t a big deal. With any luck, more and more reasonable folks will recognize that Android Phones are legitimate players in the smart phone space, they will buy loads of them and there will become plenty of functional phones to borrow when my “phone” is showing zero bars.  Heck, I’m already covered when I visit my mom.

  • Oracle’s New Memory-Optimized x86 Servers: Getting the Most Out of Oracle Database In-Memory

    - by Josh Rosen, x86 Product Manager-Oracle
    With the launch of Oracle Database In-Memory, it is now possible to perform real-time analytics operations on your business data as it exists at that moment – in the DRAM of the server – and immediately return completely current and consistent data. The Oracle Database In-Memory option dramatically accelerates the performance of analytics queries by storing data in a highly optimized columnar in-memory format.  This is a truly exciting advance in database technology.As Larry Ellison mentioned in his recent webcast about Oracle Database In-Memory, queries run 100 times faster simply by throwing a switch.  But in order to get the most from the Oracle Database In-Memory option, the underlying server must also be memory-optimized. This week Oracle announced new 4-socket and 8-socket x86 servers, the Sun Server X4-4 and Sun Server X4-8, both of which have been designed specifically for Oracle Database In-Memory.  These new servers use the fastest Intel® Xeon® E7 v2 processors and each subsystem has been designed to be the best for Oracle Database, from the memory, I/O and flash technologies right down to the system firmware.Amongst these subsystems, one of the most important aspects we have optimized with the Sun Server X4-4 and Sun Server X4-8 are their memory subsystems.  The new In-Memory option makes it possible to select which parts of the database should be memory optimized.  You can choose to put a single column or table in memory or, if you can, put the whole database in memory.  The more, the better.  With 3 TB and 6 TB total memory capacity on the Sun Server X4-4 and Sun Server X4-8, respectively, you can memory-optimize more, if not your entire database.   Sun Server X4-8 CMOD with 24 DIMM slots per socket (up to 192 DIMM slots per server) But memory capacity is not the only important factor in selecting the best server platform for Oracle Database In-Memory.  As you put more of your database in memory, a critical performance metric known as memory bandwidth comes into play.  The total memory bandwidth for the server will dictate the rate in which data can be stored and retrieved from memory.  In order to achieve real-time analysis of your data using Oracle Database In-Memory, even under heavy load, the server must be able to handle extreme memory workloads.  With that in mind, the Sun Server X4-8 was designed with the maximum possible memory bandwidth, providing over a terabyte per second of total memory bandwidth.  Likewise, the Sun Server X4-4 also provides extreme memory bandwidth in an even more compact form factor with over half a terabyte per second, providing customers with scalability and choice depending on the size of the database.Beyond the memory subsystem, Oracle’s Sun Server X4-4 and Sun Server X4-8 systems provide other key technologies that enable Oracle Database to run at its best.  The Sun Server X4-4 allows for up 4.8 TB of internal, write-optimized PCIe flash while the Sun Server X4-8 allows for up to 6.4 TB of PCIe flash.  This enables dramatic acceleration of data inserts and updates to Oracle Database.  And with the new elastic computing capability of Oracle’s new x86 servers, server performance can be adapted to your specific Oracle Database workload to ensure that every last bit of processing power is utilized.Because Oracle designs and tests its x86 servers specifically for Oracle workloads, we provide the highest possible performance and reliability when running Oracle Database.  To learn more about Sun Server X4-4 and Sun Server X4-8, you can find more details including data sheets and white papers here. Josh Rosen is a Principal Product Manager for Oracle’s x86 servers, focusing on Oracle’s operating systems and software.  He previously spent more than a decade as a developer and architect of system management software. Josh has worked on system management for many of Oracle's hardware products ranging from the earliest blade systems to the latest Oracle x86 servers.

  • Java Script – Content delivery networks (CDN) can bit you in the butt.

    - by Ryan Ternier
    As much as I love the new CDN’s that Google, Microsoft and a few others have publically released, there are some strong gotchas that could come up and bite you in the ass if you’re not careful. But before we jump into that, for those that are not 100% sure what a CDN is (besides Canadian).   Content Delivery Network. A way of distributing your static content across various servers in different physical locations.  Because this static content is stored on many servers around the world, whenever a user needs to access this content, they are given the closest server to their location for this data. Already you can probably see the immediate bonuses to a system like this: Lower bandwidth Even small script files downloaded thousands of times will start to take a noticeable hit on your bandwidth meter. Less connections/hits to your web server which gives better latency If you manage many servers, you don’t need to manually update each server with scripts. A user will download a script for each website they visit. If a user is redirected to many domains/sub-domains within your web site, they might download many copies of the same file. When a system sees multiple requests from the same  domain, they will ignore the download   Those are just a handful of the many bonuses a CDN will give you. And for the average website, a CDN is great choice. Check out the following CDN links for their solutions: Google AJAX Library: http://code.google.com/apis/ajaxlibs/ Microsoft Ajax library: http://www.asp.net/ajaxlibrary/cdn.ashx The Gotcha There is always a catch. Here are some issues I found with using CDN’s that hopefully can help you make your decision. HTTP / HTTPS If you are running a website behind SSL, make sure that when you reference your CDN data that you use https:// vs. http://. If you forget this users will get a very nice message telling them that their secure connection is trying to access unsecure data. For a developer this is fairly simple, but general users will get a bit anxious when seeing this. Trusted Sites Internet Explorer has this really nifty feature that allows users to specify what sites they trust, and by some defaults IE7 only allows trusted sites to be viewed.  No problem, they set your website as trusted. But what about your CDN? If a user sets your websites to trusted, but not the CDN, they will not download those static files. This has the potential to totally break your web site. Pedantic Network Admins This alone is sometimes the killer of projects. However, always be careful when you are going to use a CDN for a professional project. If a network / security admin sees that you’re referencing an outside source, or that a call from a website might hit an outside domain.. panties will be bunched, emails will be spewed out and well, no one wants that.

  • Ask the Readers: Backing Your Files Up – Local Storage versus the Cloud

    - by Asian Angel
    Backing up important files is something that all of us should do on a regular basis, but may not have given as much thought to as we should. This week we would like to know if you use local storage, cloud storage, or a combination of both to back your files up. Photo by camknows. For some people local storage media may be the most convenient and/or affordable way to back up their files. Having those files stored on media under your control can also provide a sense of security and peace of mind. But storing your files locally may also have drawbacks if something happens to your storage media. So how do you know whether the benefits outweigh the disadvantages or not? Here are some possible pros and cons that may affect your decision to use local storage to back up your files: Local Storage Pros You are in control of your data Your files are portable and can go with you when needed if using external or flash drives Files are accessible without an internet connection You can easily add more storage capacity as needed (additional drives, etc.) Cons You need to arrange room for your storage media (if you have multiple externals drives, etc.) Possible hardware failure No access to your files if you forget to bring your storage media with you or it is too bulky to bring along Theft and/or loss of home with all contents due to circumstances like fire If you are someone who is always on the go and needs to travel as lightly as possible, cloud storage may be the perfect way for you to back up and access your files. Perhaps your laptop has a hard-drive failure or gets stolen…unhappy events to be sure, but you will still have a copy of your files available. Perhaps a company wants to make sure their records, files, and other information are backed up off site in case of a major hardware or system failure…expensive and/or frustrating to fix if it happens, but once again there is a nice backup ready to go once things are fixed. As with local storage, here are some possible pros and cons that may influence your choice of cloud storage to back up your files: Cloud Storage Pros No need to carry around flash or bulky external drives All of your files are accessible wherever there is an internet connection No need to deal with local storage media (or its’ upkeep) Your files are still safe if your home is broken into or other unfortunate circumstances occur Cons Your files and data are not 100% under your control Possible hardware failure or loss of files on the part of your cloud storage provider (this could include a disgruntled employee wreaking havoc) No access to your files if you do not have an internet connection The cloud storage provider may eventually shutdown due to financial hardship or other unforeseen circumstances The possibility of your files and data being stolen by hackers due to a security breach on the part of your cloud storage provider You may also prefer to try and cover all of the possibilities by using both local and cloud storage to back up your files. If something happens to one, you always have the other to fall back on. Need access to those files at or away from home? As long as you have access to either your storage media or an internet connection, you are good to go. Maybe you are getting ready to choose a backup solution but are not sure which one would work better for you. Here is your chance to ask your fellow HTG readers which one they would recommend.

  • Pie Charts Just Don't Work When Comparing Data - Number 10 of Top 10 Reasons to Never Ever Use a Pie

    - by Tony Wolfram
    When comparing data, which is what a pie chart is for, people have a hard time judging the angles and areas of the multiple pie slices in order to calculate how much bigger one slice is than the others. Pie Charts Don't Work A slice of pie is good for serving up a portion of desert. It's not good for making a judgement about how big the slice is, what percentage of 100 it is, or how it compares to other slices. People have trouble comparing angles and areas to each other. Controlled studies show that people will overestimate the percentage that a pie slice area represents. This is because we have trouble calculating the area based on the space between the two angles that define the slice. This picture shows how a pie chart is useless in determing the largest value when you have to compare pie slices.   You can't compare angles and slice areas to each other. Human perception and cognition is poor when viewing angles and areas and trying to make a mental comparison. Pie charts overload the working memory, forcing the person to make complicated calculations, and at the same time make a decision based on those comparisons. What's the point of showing a pie chart when you want to compare data, except to say, "well, the slices are almost the same, but I'm not really sure which one is bigger, or by how much, or what order they are from largest to smallest. But the colors sure are pretty. Plus, I like round things. Oh,was I suppose to make some important business decision? Sorry." Bad Choices and Bad Decisions Interaction Designers, Graphic Artists, Report Builders, Software Developers, and Executives have all made the decision to use pie charts in their reports, software applications, and dashboards. It was a bad decision. It was a poor choice. There are always better options and choices, yet the designer still made the decision to use a pie chart. I'll expore why people make such poor choices in my upcoming blog entires. (Hint: It has more to do with emotions than with analytical thinking.) I've outlined my opinions and arguments about the evils of using pie charts in "Countdown of Top 10 Reasons to Never Ever Use a Pie Chart." Each of my next 10 blog entries will support these arguments with illustrations, examples, and references to studies. But my goal is not to continuously and endlessly rage against the evils of using pie charts. This blog is not about pie charts. This blog is about understanding why designers choose to use a pie chart. Why, when give better alternatives, and acknowledging the shortcomings of pie charts, do designers over and over again still freely choose to place a pie chart in a report? As an extra treat and parting shot, check out the nice pie chart that Wikipedia uses to illustrate the United States population by state.   Remember, somebody chose to use this pie chart, with all its glorious colors, and post it on Wikipedia for all the world to see. My next blog will give you a better alternative for displaying comparable data - the sorted bar chart.

  • How do you install a USB CD Rom drive?

    - by Matt Allen
    Hello, I recently purchased a USB CD ROM drive, but I don't know how to get it to work with my computer which runs Ubuntu 10.04. http://www.amazon.com/gp/product/B00303H908/ref=oss_product When I issue the lsusb command, it shows up as: Bus 002 Device 016: ID 05e3:0701 Genesys Logic, Inc. USB 2.0 IDE Adapter The computer doesn't recognize it automatically. How can I get this drive to show up as an actual drive on my computer? If this particular drive can't handle Linux, can you recommended one which can and provide a link to it so I can purchase it? Thanks!

  • Regular Expressions Cookbook Is in The Money—Win a Copy

    - by Jan Goyvaerts
    %COOKBOOKFRAME%You may have heard some people say that most book authors never get any royalties. That’s not true because most authors get an advance royalty that is paid before the book is published. That’s the author’s main incentive for writing the book, at least as far as money is concerned. (If money is your main concern, don’t write books.) What is true is that most authors never see any money beyond the advance royalty. Royalty rates are very low. A 10% royalty of the publisher’s price is considered normal. The publisher’s price is usually 45% of the retail price. So if you pay full price in a bookstore, the author gets 4.5% of your money. If there’s more than one author, they split the royalty. It doesn’t take a math degree to figure out that a book needs to sell quite a few copies for the royalty to add up to a meaningful amount of money. But Steven and I must have done something right. Regular Expressions Cookbook is in the money. My royalty statement for the 3rd quartier of 2009, which is the 2nd quarter that the book was on the market, came with a check. I actually received it last month but didn’t get around to blogging about. The amount of the check is insignificant. The point is that the balance is no longer negative. I’m taking this opportunity to pat myself and my co-author on the back. To celebrate the occassion O’Reilly has offered to sponsor a give-away of five (5) copies of Regular Expressions Cookbook. These are the rules of the game: You must post a comment to this blog article including your actual name and actual email address. Names are published, email addresses are not. Comments are moderated by myself (Jan Goyvaerts). If I consider a comment to be offensive or spam it will not be published and not be eligible for any prize. If you don’t know what to say in the comment, just wish me a happy 100000nd birthday, so I don’t have to feel so bad about entering the 6-bit era. Each person commenting has only one chance to win, regardless of the number of comments posted. O’Reilly will be provided with the names and email addresses of the winners (and those email addresses only) in order to arrange delivery. Each winner can choose to receive a printed copy or ebook (DRM-free PDF). If you choose the printed book, O’Reilly pays for shipping to anywhere in the world but not for any duties or taxes your country may impose on books imported from the USA. If you choose the ebook, you’ll need to create an O’Reilly account that is then granted access to the PDF download. You can make your choice after you’ve won, so it doesn’t influence your chance of winning. Contest ends 28 February 2010, GMT+7 (Thai time). Chosen by five calls to Random(78)+1 in Delphi 2010, the winners are: 48: Xiaozu 45: David Chisholm 19: Miquel Burns 33: Aaron Rice 17: David Laing Thanks to everybody who participated. The winners have been notified by email on how to collect their prize.

  • Download YouTube Videos the Easy Way

    You can’t be online all the time, and despite the majority of YouTube videos being nut-shots and Lady Gaga parodies, there is a lot of great content that you might want to download and watch offline. There are some programs and browser extensions to do this, but we’ve found that the easiest and quickest method is a bookmarklet that was originally posted on the Google Operating System blog (it’s since been removed). It will let you download standard quality and high-definition movies as MP4 files. Also, because it’s a bookmarklet, it will work on any modern web browser, and on any operating system! Installing the bookmarket is easy – just drag and drop the Get YouTube video link below to the bookmarks bar of your browser of choice. If you’ve hidden the bookmark bar, in most browsers you can right-click on the link and save it to your bookmarks. Get YouTube video   With the bookmarklet available in your browser, go to the YouTube video that you’d like to download. Click on the Get YouTube video link in your bookmarks bar, or in the bookmarks menu, wherever you saved it earlier. You will notice some new links appear below the description of the video. If you download the standard definition file, it will save as “video.mp4” by default. However, if you download the high definition file, it will save with the same name as the title of the video. There are many methods of downloading YouTube videos…but we think this is the easiest and quickest method. You don’t have to install anything or use up resources, but you can still get a link to download an MP4 with one click. Do you use a different method to download Youtube videos?

  • Rotate a Video 90 degrees with VLC or Windows Live Movie Maker

    - by DigitalGeekery
    Have you ever captured video with your cell phone or camcorder only to discover when you play it back on your computer that the video is rotated 90 degrees? Or maybe you shot it that way on purpose because you preferred portrait style to a landscape view? Before you go straining your neck or flipping your monitor on it’s side to watch your video, we’ll show you a few easier methods. If you simply want to rotate the video while you watch it, we’ll show you how to accomplish that with VLC Media Player. If you want to convert the video so it is rotated permanently, we’ll show you how to do that with Windows Live Movie Maker and output your video as a WMV file. Rotate and Watch a Video in VLC Download, install, and run VLC Media Player. (See download link below)   Open your video file by going to Media  > Open File… and browsing for your file. Or, by just dragging and dropping your video onto the VLC player.   Choose Tools from the Menu bar and select Effects and Filters. On the Video Effects tab, tick the Transform checkbox and choose your degrees of rotation. The video is rotated counter-clockwise, so to rotate clockwise 90 degrees you’ll want to choose Rotate by 270 degrees.   Now you can enjoy your video the way it was intended to be viewed. Rotate and Convert the Video with Windows Live Movie Maker Starting with Windows 7, Windows Movie Maker no longer comes pre-installed with the OS. It’s now part of the Windows Live suite that is available as a separate, free download for Windows 7 and Vista. (Windows XP is not supported) You can find the link to our detailed instruction on how to install Windows Live at the end of the article. To add your video files to Windows Movie Maker, click on Add videos and photos on the Home tab, or drag and drop the video into the blank area on the right side of the application. Next, you’ll need to rotate the video. Staying on the Home tab, click on the Rotate right 90° or Rotate left 90°.   You’ll see your video is now oriented properly on the left.   To save and convert your video to WMV format, click the Movie Maker tab just to the left of the Home tab. Hover your cursor over Save movie, and then select your output settings. You also have the option to burn directly to DVD. Browse for a location to save it and rename the output file if you’d like. Click Save. You’ll be notified when the file is complete. Now you’ll have your video properly oriented in WMV file format.   These are two rather easy ways to accomplish rotating your video. Unfortunately, Windows Live Movie Maker doesn’t give you a lot of  options for output. If you want to output to a file, your only choice is WMV format or DVD. However, previous versions will also allow you to export to AVI. How-To Geek’s Install Windows Live Essentials In Windows 7 Article.

  • Talking JavaOne with Rock Star Simon Ritter

    Oracle’s Java Technology Evangelist Simon Ritter is well known at JavaOne for his quirky and fun-loving sessions, which, this year include: CON4644 -- “JavaFX Extreme GUI Makeover” (with Angela Caicedo on how to improve UIs in JavaFX) CON5352 -- “Building JavaFX Interfaces for the Real World” (Kinect gesture tracking and mind reading) CON5348 -- “Do You Like Coffee with Your Dessert?” (Some cool demos of Java of the Raspberry Pi) CON6375 -- “Custom JavaFX Charts: (How to extend JavaFX Chart controls with some interesting things) I recently asked Ritter about the significance of the Raspberry Pi, the topic of one of his sessions that consists of a credit card-sized single-board computer developed in the UK with the intention of stimulating the teaching of basic computer science in schools. “I don't think there's one definitive thing that makes the RP significant,” observed Ritter, “but a combination of things that really makes it stand out. First, it's the cost: $35 for what is effectively a completely usable computer. OK, so you have to add a power supply, SD card for storage and maybe a screen, keyboard and mouse, but this is still way cheaper than a typical PC. The choice of an ARM processor is also significant, as it avoids problems like cooling (no heat sink or fan) and can use a USB power brick.  Combine these two things with the immense groundswell of community support and it provides a fantastic platform for teaching young and old alike about computing, which is the real goal of the project.”He informed me that he’ll be at the Raspberry Pi meetup on Saturday (not part of JavaOne). Check out the details here.JavaFX InterfacesWhen I asked about how JavaFX can interface with the real world, he said that there are many ways. “JavaFX provides you with a simple set of programming interfaces that can create complex, cool and compelling user interfaces,” explained Ritter. “Because it's just Java code you can combine JavaFX with any other Java library to provide data to display and control the interface. What I've done for my session is look at some of the possible ways of doing this using some of the amazing hardware that's available today at very low cost. The Kinect sensor has added a new dimension to gaming in terms of interaction; there's a Java API to access this so you can easily collect skeleton tracking data from it. Some clever people have also written libraries that can track gestures like swipes, circles, pushes, and so on. We use these to control parts of the UI. I've also experimented with a Neurosky EEG sensor that can in some ways ‘read your mind’ (well, at least measure some of the brain functions like attention and meditation).  I've written a Java library for this that I include as a way of controlling the UI. We're not quite at the stage of just thinking a command though!” Here Comes Java EmbeddedAnd what, from Ritter’s perspective, is the most exciting thing happening in the world of Java today? “I think it's seeing just how Java continues to become more and more pervasive,” he said. “One of the areas that is growing rapidly is embedded systems.  We've talked about the ‘Internet of things’ for many years; now it's finally becoming a reality. With the ability of more and more devices to include processing, storage and networking we need an easy way to write code for them that's reliable, has high performance, and is secure. Java fits all these requirements. With Java Embedded being a conference within a conference, I'm very excited about the possibilities of Java in this space.”Check out Ritter’s sessions or say hi if you run into him.

  • Opening the Internet Settings Dialog and using Windows Default Network Settings via Code

    - by Rick Strahl
    Ran into a question from a client the other day that asked how to deal with Internet Connection settings for running  HTTP requests. In this case this is an old FoxPro app and it's using WinInet to handle the actual HTTP connection. Another client asked a similar question about using the IE Web Browser control and configuring connection properties. Regardless of platform or tools used to do HTTP connections, you can probably configure custom connection and proxy settings in your application to configure http connection settings manually. However, this is a repetitive process for each application requires you to track system information in your application which is undesirable. Often it's much easier to rely on the system wide proxy settings that Windows provides via the Internet Settings dialog. The dialog is a Control Panel applet (inetcpl.cpl) and is the same dialog that you see when you pop up Internet Explorer's Options dialog: This dialog controls the Windows connection properties that determine how the Windows HTTP stack connects to the Internet and how Proxy's are used if configured. Depending on how the HTTP client is configured - it can typically inherit and use these global settings. Loading the Settings Dialog Programmatically The settings dialog is a Control Panel applet with the name of: inetcpl.cpl and you can use any Shell execution mechanism (Run dialog, ShellExecute API, Process.Start() in .NET etc.) to invoke the dialog. Changes made there are immediately reflected in any applications that use the default connection settings. In .NET you can simply do this to bring up the Internet Settings dialog with the Connection tab enabled: Process.Start("inetcpl.cpl",",4"); In FoxPro you can simply use the RUN command to execute inetcpl.cpl: lcCmd = "inetcpl.cpl ,4" RUN &lcCmd Using the Default Connection/Proxy Settings When using WinInet you specify the Http connect type in the call to InternetOpen() like this (FoxPro code here): hInetConnection=; InternetOpen(THIS.cUserAgent,0,; THIS.chttpproxyname,THIS.chttpproxybypass,0) The second parameter of 0 specifies that the default system proxy settings should be used and it uses the settings from the Internet Settings Connections tab. Other connection options for HTTP connections include 1 - direct (no proxies and ignore system settings), 3 - explicit Proxy specification. In most situations a connection mode setting of 0 should work. In .NET HTTP connections by default are direct connections and so you need to explicitly specify a default proxy or proxy configuration to use. The easiest way to do this is on the application level in the config file: <configuration> <system.net> <defaultProxy> <proxy bypassonlocal="False" autoDetect="True" usesystemdefault="True" /> </defaultProxy> </system.net> </configuration> You can do the same sort of thing in code specifying the proxy explicitly and using System.Net.WebProxy.GetDefaultProxy(). So when making HTTP calls to Web Services or using the HttpWebRequest class you can set the proxy with: StoreService.Proxy = WebProxy.GetDefaultProxy(); All of this is pretty easy to deal with and in my opinion is a way better choice to managing connection settings than having to track this stuff in your own application. Plus if you use default settings, most of the time it's highly likely that the connection settings are already properly configured making further configuration rare.© Rick Strahl, West Wind Technologies, 2005-2011Posted in Windows  HTTP  .NET  FoxPro   Tweet (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • Install Problem (Ubuntu Server 10.04) with USB as it reboots when I hit 'enter' for 'Install Ubuntu Server' option! Help

    - by Alastair
    We cannot seem to install Ubuntu Server with USB as it reboots when I hit 'enter' for 'Install Ubuntu Server' option. My friend wants to try setting up a server so; we downloaded Ubuntu Server 10.04.4 we created a boot CD and installed ubuntu server no problem at all. But then the problem arose the hardrive we wanted to use is a 1tb sata drive and the computer orginally has 40gb IDE. So I bought a Sata to IDE and IDE to Sata converter from: http://www.microdirect.co.uk/Home/Product/52926/IDE-to-SATA-converter---Converts-IDE-HDD-to-SATA-inc-sata-data-and-power-cables Unfortunately this converter means I cannot plug in the IDE cable meaning I only have one IDE connection i.e CD drive has to be disconnected for the 1tb sata Hardrive to be connected. So now the 1tb drive is connected, powered it on opened the bios to make sure the hdd appeared it did as ST3ASDAPFKG (somthing like that). Fortunately the computer supports USB booting, so I read ubuntu server usb install instructions I tried: Startup Disk Creator & Unebootin Startup Disk Creator made the usb bootable with the 'ubuntu-10.04.4-server-i386.iso' All looked fine stuck the usb drive in, booted the machine up and I am quickly presented with ubuntu language choice. I hit enter to select English then I am presented with: Install Ubuntu Server, Install Ubuntu Enterprise Cloud, Check Disk for defects, test memory, Boot from first hard disk, Rescue a broken system I can move up and down the menu fine everything seems ok, I select 'Install Ubuntu Server', computer just hangs and screen either goes blank or locks. So I rebooted the computer loads the same menus fine, I select 'Install Ubuntu Server' hit 'enter' and the computer just restarts then brings me back to the same menu. hmmm Then I tried choosing the rest of the options separately: Install Ubuntu Server, Install Ubuntu Enterprise Cloud, Check Disk for defects, test memory, Boot from first hard disk, Rescue a broken system computer just restarts and back to the same ubuntu menu every-time. Grrrr At this point I wish I actually new how to command line install or something but I don't have a clue how to do that. So I tried hitting 'f6' for 'other options' and I tried them all in various combinations and individually. No Luck: (Expert mode, acpi=off, noapic, nolapic, edd=on, nodmraid, nomodeset, Free Software only) At this point I am wondering if it is a bios setting causing problems, I tried turning every option in there on off that I don't understand. No Luck. I then discovered by accident if you hit esc in the ubuntu install menu it says "you are leaving the graphical boot menu and starting the text mode interface" I hit 'Ok'. Next a prompt pops up saying 'boot:' One time it responded when I typed somthing with 'Cannot find kernal image (something like that but since then it just restarts when I hit enter in that prompt). I had a browse on the net and found someone suggesting removing quiet from install command for 'Install Ubuntu Server'. Made no difference at all just reboots... Orginal boot options noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu-server.seed initrd=/install/initrd.gz quiet -- Modified boot options noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu-server.seed initrd=/install/initrd.gz -- Still I cannot install Ubuntu Server by USB as it, reboots when I hit 'enter' for 'Install Ubuntu Server' option. This is a real pain as we cannot take the 1tb Sata Hardrive and swap it for IDE to be able to use the cd drive. Why is is it so hard to install ubuntu server with usb? I have wasted a full day and half on this really frustrated any help would be amazing! I know the answers out there just seems a bit illusive at the moment!

  • Steps for MySQL DB Replication

    - by Manish Agrawal
    Following are the steps for MySQL Replication implementation on Linux machine: Pre-implementation steps for DB Replication:   1.    Identify the databases to be replicated 2.    Identify the tables to be ignored during replication per database for example log tables 3.  Carefully identify and replace the variables and paths(locations) mentioned (in bold) in the commands given below with appropriate values 4.  Schedule the maintenance activity in odd hours as these activities will affect all the databases on Master database server       Implementation steps for DB Replication:     1.    Configure the /etc/my.cnf file on Master database server to enable Binary logging, setting of server id and configuring of dbnames for which logging should be done. [mysqld] log-bin=mysql-bin server-id=1 binlog-do-db = dbname   Note: You can specify multiple DB in binlog-do-db by using comma separated dbname values like: dbname1, dbname2, …, dbnameN   2.    On Master database, Grant Replication Slave Privileges, by executing following command on mysql prompt mysql> GRANT REPLICATION SLAVE ON *.* TO slaveuser@<hostname> identified by ‘slavepassword’;   3.    Stop the Master & Slave database by giving the command      mysqladmin shutdown   4.    Start the Master database by giving the command      /usr/local/mysql-5.0.22/bin/mysqld_safe --user=user&     5.    mysql> FLUSH TABLES WITH READ LOCK; Note: Leave the client (putty session) from which you issued the FLUSH TABLES statement running, so that the read lock remains in effect. If you exit the client, the lock is released. 6.    mysql > SHOW MASTER STATUS;          +---------------+----------+--------------+------------------+          | File          | Position | Binlog_Do_DB | Binlog_Ignore_DB |          +---------------+----------+--------------+------------------+          | mysql-bin.003 | 117       | dbname       |                  |          +---------------+----------+--------------+------------------+ Note: Note this information as this will be required while starting of Slave and replication in later steps   7.    Take MySQL dump by giving the following command, In another session window (putty window) run the following command: mysqldump –u user --ignore-table=dbname.tbl_name -–ignore-table=dbname.tbl_name2 --master-data dbname > dbname_dump.db Note: When choosing databases to include in the dump, remember that you will need to filter out databases on each slave that you do not want to include in the replication process.     8.    Unlock the tables on Master by giving following command: mysql> UNLOCK TABLES;   9.    Copy the dump file to Slave DB server   10.  Startup the Slave by using option --skip-slave      /usr/local/mysql-5.0.22/bin/mysqld_safe --user=user --skip-slave&   11.  Restore the dump file on Slave DB server      mysql –u user dbname < dbname_dump.db   12.  Stop the Slave database by giving the command      mysqladmin shutdown   13.  Configure the /etc/my.cnf file on the Slave database server [mysqld] server-id=2 replicate-ignore-table = dbname.tablename   14.  Start the Slave Mysql Server with 'replicate-do-db=DB name' option.      /usr/local/mysql-5.0.22/bin/mysqld_safe --user=user --replicate-do-db=dbname --skip-slave   15.  Configure the settings at Slave server for Master host name, log filename and position within the log file as shown in Step 6 above Use Change Master statement in the MySQL session mysql> CHANGE MASTER TO MASTER_HOST='<master_host_name>', MASTER_USER='<replication_user_name>', MASTER_PASSWORD='<replication_password>', MASTER_LOG_FILE='<recorded_log_file_name>', MASTER_LOG_POS=<recorded_log_position>;   16.  On Slave Servers mysql prompt give the following command: a.     mysql > START SLAVE; b.    mysql > SHOW SLAVE STATUS;         Note: To stop slave for backup or any other activity you can use the following command on the Slave Servers mysql prompt: mysql> STOP SLAVE     Refer following links for more information on MySQL DB Replication: http://dev.mysql.com/doc/refman/5.0/en/replication-options.html http://crazytoon.com/2008/04/21/mysql-replication-replicate-by-choice/ http://dev.mysql.com/doc/refman/5.0/en/mysqldump.html
