  • Visual Studio 2010 Productivity Power Tool Extensions

    - by ScottGu
    Last month I blogged about the Extension Manager that is built-into VS 2010 – as well as about a cool VS 2010 PowerCommands extension that provides some extra features for Visual Studio.  The Visual Studio 2010 Extension Manager provides an easy way for developers to quickly find and install extensions and plugins that enhance the built-in functionality to VS 2010. New VS 2010 Productivity Power Tools Release Earlier this week Jason Zander announced the availability of a new VS 2010 Productivity Power Tools release that includes a bunch of great new VS 2010 extensions that provide a bunch of cool new functionality for you to take advantage of.  You can download and install the release for free here.  Some of the code editor improvements it provides include: Entire Line Highlighting: Makes it easier to track cursor location within the editor Entire Line Selection: Triple Clicking a line in the code editor now selects the entire line (like with MS Word) Code Block Movement: Use Alt+Up/Down Arrow now moves selected code blocks up/down in the editor Consistent Tabs vs. Spaces: Ensure consistent tab vs. space usage across your projects Colorized Parameters: It is now easier to see/identify method parameters Column Guide: You can now add vertical column guidelines to help with text alignment and sizes Align assignments: Makes it easier to line-up multiple variable assignments within your code HTML Clipboard Support: Copy/paste code from VS into an HTML buffer (useful for blogging!) Ctrl + Click Go to Definition: You can now hold down the Ctrl key and click a type to go to its definition It also includes several tab management improvements for managing document tabs within the IDE: Show Close Button in Tab Well: Shows a close button in document well for the active tab (like VS 2008 did) Colored Tabs: You can now select the color of each document tab by project or by regex Pinned Tabs: Enables you to pin tabs to keep them always visible and available Vertical Tabs: You can now show document tabs vertically to fit more tabs than normal Remove Tabs by Usage Order: Better behavior when adding new tabs and one needs to be hidden for space reasons Sort Tabs by Project: Tabs can be sorted by project they belong to, keeping them grouped together Sort Tabs Alphabetically: Tabs can be sorted alphabetically And last – but not least – it includes a new and improved “Add Reference” dialog: This new Add Reference dialog caches assembly information – which means it loads within a second or two (note: the very first time it still loads assembly data – but it then caches it and makes it fast afterwards). The new Add Reference dialog also now includes searching support – making it easier to find the assembly you are looking for. You can read more about all of the above improvements in Jason’s blog post about the release. New Visualization and Modeling Feature Pack Release Earlier this week we also shipped a new feature pack that adds additional modeling and code visualization features to VS 2010 Ultimate.  You can download it here. The Visualization and Modeling Feature Pack includes a bunch of great new capabilities including: Web Site Visualization: New support for generating a DGML visualization for ASP.NET projects C/C++ Native Code Visualization: New support for generating DGML diagrams for C/C++ projects Generate Code from UML Class Diagrams: You can now generate code from your UML diagrams Create UML Class Diagrams from Code: Create UML diagrams from existing code bases Import UML from XML: Import UML class, sequence, and use case elements from XMI 2.1 files Custom Validation Layer Rules: Write custom code to create, modify, and validate layer diagrams Jason’s blog post covers more about these features as well. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • SQL SERVER – Attach mdf file without ldf file in Database

    - by pinaldave
    Background Story: One of my friends recently called up and asked me if I had spare time to look at his database and give him a performance tuning advice. Because I had some free time to help him out, I said yes. I asked him to send me the details of his database structure and sample data. He said that since his database is in a very early stage and is small as of the moment, so he told me that he would like me to have a complete database. My response to him was “Sure! In that case, take a backup of the database and send it to me. I will restore it into my computer and play with it.” He did send me his database; however, his method made me write this quick note here. Instead of taking a full backup of the database and sending it to me, he sent me only the .mdf (primary database file). In fact, I asked for a complete backup (I wanted to review file groups, files, as well as few other details).  Upon calling my friend,  I found that he was not available. Now,  he left me with only a .mdf file. As I had some extra time, I decided to checkout his database structure and get back to him regarding the full backup, whenever I can get in touch with him again. Technical Talk: If the database is shutdown gracefully and there was no abrupt shutdown (power outrages, pulling plugs to machines, machine crashes or any other reasons), it is possible (there’s no guarantee) to attach .mdf file only to the server. Please note that there can be many more reasons for a database that is not getting attached or restored. In my case, the database had a clean shutdown and there were no complex issues. I was able to recreate a transaction log file and attached the received .mdf file. There are multiple ways of doing this. I am listing all of them here. Before using any of them, please consult the Domain Expert in your company or industry. Also, never attempt this on live/production server without the presence of a Disaster Recovery expert. USE [master] GO -- Method 1: I use this method EXEC sp_attach_single_file_db @dbname='TestDb', @physname=N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\TestDb.mdf' GO -- Method 2: CREATE DATABASE TestDb ON (FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\TestDb.mdf') FOR ATTACH_REBUILD_LOG GO Method 2: If one or more log files are missing, they are recreated again. There is one more method which I am demonstrating here but I have not used myself before. According to Book Online, it will work only if there is one log file that is missing. If there are more than one log files involved, all of them are required to undergo the same procedure. -- Method 3: CREATE DATABASE TestDb ON ( FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\TestDb.mdf') FOR ATTACH GO Please read the Book Online in depth and consult DR experts before working on the production server. In my case, the above syntax just worked fine as the database was clean when it was detached. Feel free to write your opinions and experiences for it will help the IT community to learn more from your suggestions and skills.

  • Add Windows 7’s AeroSnap Feature to Vista and XP

    - by Asian Angel
    Are you using Windows Vista or XP and want that Windows 7 AeroSnap goodness on your own system? Then join us as we look at AeroSnap for Windows Vista and XP. Note: Requires .NET Framework 2.0 or higher (link provided at bottom of article). Setup What exactly does AeroSnap do you might ask…here is a quote directly from the website: “AeroSnap is a simple but powerful application that allows you to resize, arrange or maximize your desktop windows with just drag’n'drop. Simply drag a window to a side of your desktop to snap it or drag it to the top to maximize. When you drag it back to the last position, the last window size will be restored.” As soon as you have finished installing AeroSnap and started it for the first time the only item that will be visible is the “System Tray Icon”. Before going any further you should take a moment to view and make any desired adjustments in the “Options”. Note: AeroSnap works with multiple monitors. You may want to have AeroSnap start with Windows each time but the really nice setting to enable here is the “Snap Preview”. If you are using AeroSnap on Vista and have Aero enabled this will really be nice. The second portion may be of interest for those who would like to enable the keyboard shortcut function. One point worth noting about this screen is that the highest number of pixels from the screen’s edge that you can set AeroSnap for is 20 pixels. AeroSnap in Action AeroSnap is extremely easy to use…just grab the top of an app window and drag it to the left, right, or top of your screen. Since we installed this on Windows Vista we made certain to enable the “Snap Preview” in the “Options”.  We started off with dragging our Firefox 3.7 window towards the left…once we got close to the edge of the screen you can see that the left half of the screen temporarily “shaded over”. Note: The “Snap Preview” displays on the left and right movements but not the top movement. Releasing Firefox snapped it right into the “shaded over” part of the screen. The great thing about AeroSnap is that it is really easy to return the app window to it former size…all that you have to do is simply click on and grab the top portion of the app window. Moving Firefox towards the top of our screen and… It quickly snaps into filling the screen. One thing that we did notice is that the window did not “Maximize” as per the function for the button in the upper right corner. Dragging towards the right side now… And snap! Tucked in all nice and neat… You can minimize the app windows to the Taskbar and they will return to their previous “snap area” when “maximized” again. Conclusion If you have been wanting to add Windows 7’s AeroSnap goodness to your Vista and XP systems then you should definitely give this app a try. AeroSnap is very easy to set up and operate… Links Download AeroSnap for Windows Vista & XP Download the .NET Framework Similar Articles Productive Geek Tips Using Windows 7 or Vista System RestoreRoundup: 16 Tweaks to Windows Vista Look & FeelSelect Files using Check Boxes in Windows VistaSpeed up Your Windows Vista Computer with ReadyBoostHow-To Geek Bounty: $103.24(Paid!) for Active Desktop for Vista TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips DVDFab 6 Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 Add a Custom Title in IE using Spybot or Spyware Blaster When You Need to Hail a Taxi in NYC Live Map of Marine Traffic NoSquint Remembers Site Specific Zoom Levels (Firefox) New Firefox release 3.6.3 fixes 1 Critical bug Dark Side of the Moon (8-bit)

  • JavaScript Browser Hacks

    Recently during one of my client side scripting classes, I was trying to show my students some basic examples of JavaScript as an introduction to the language.  My first basic example was to show an alert box using JavaScript via the address bar. The student’s reaction to my browser hack example really caught me off guard in a good way. After programming with a language for close to 10 years you start to lose the "Awe Cool!" effect that new learners of a language experience when writing code. New learns of JavaScript are the reason why I created this post. Please enjoy. Note: Place JavaScript in to address bar and then press the enter key. Example 1: JavaScript Alert box displaying My name: John Doe Javascript:alert('My name: \n John Doe') ; Example 2: JavaScript alert box displaying name entered by user. javascript:alert('My name: \n ' + prompt('Enter Name','Name')) ; Example 3: JavaScript alert box displaying name entered by user, and then displays the length of the name. javascript:var name= prompt('Enter Name','Name'); alert('My name: \n ' + name); alert(name.length); If you notice, the address bar will execute JavaScript on the current page loaded in the browser using the Document Object Model (DOM). Additionally, the address bar will allow multiple lines to be executed sequentially even though all of the code is contained within one line due to the fact that the JavaScript interpreter uses the “;” to indicate where a line of ends and a new one begins. After doing a little more research on the topic of JavaScript Browser Hacks I found a few other cool JavaScript hacks which I will list below. Example 4: Make any webpage editableSource: http://www.openjason.com/2008/09/02/browser-hack-make-any-web-page-editable/ javascript:document.body.contentEditable='true'; document.designMode='on'; void 0; Example 5: CHINESE DRAGON DANCING Source: http://nzeyi.wordpress.com/2009/06/01/dwrajaxjavascript-hacks-the-secrets-of-javascript-in-the-adress-bar/ javascript:R=0;x1=0.1;y1=0.05;x2=0.25;y2=0.24;x3=1.6; y3=0.24;x4=300;y4=200;x5=300;y5=200;DI=document.links; DIL=DI.length;A=function(){for(i=0;i-DIL;i++){DI[i].style. position='absolute';DI[i].style.left=Math.sin(R*x1+i*x2+x3)*x4+ x5;DI[i].style.top=Math.cos(R*y1+i*y2+y3)*y4+y5}R++;}; setInterval('A()',5);void(0); Example 6: Reveal content stored in password protected fields javascript:(function(){var s,F,j,f,i; s = “”; F = document.forms; for(j=0; j Example 7: Force user to close browser windowSource: http://forums.digitalpoint.com/showthread.php?t=767053 javascript:while(1){alert('Restart your brower to close this box!')} Learn more about JavaScript Browser Hacks.

  • SharePoint.DesignFactory.ContentFiles–building WCM sites

    - by svdoever
    One of the use cases where we use the SharePoint.DesignFactory.ContentFiles tooling is in building SharePoint Publishing (WCM) solutions for SharePoint 2007, SharePoint 2010 and Office365. Publishing solutions are often solutions that have one instance, the publishing site (possibly with subsites), that in most cases need to go through DTAP. If you dissect a publishing site, in most case you have the following findings: The publishing site spans a site collection The branding of the site is specified in the root site, because: Master pages live in the root site (/_catalogs/masterpage) Page layouts live in the root site (/_catalogs/masterpage) The style library lives in the root site ( /Style Library) and contains images, css, javascript, xslt transformations for your CQWP’s, … Preconfigured web parts live in the root site (/_catalogs/wp) The root site and subsites contains a document library called Pages (or your language-specific version of it) containing publishing pages using the page layouts and master pages The site collection contains content types, fields and lists When using the SharePoint.DesignFactory.ContentFiles tooling it is very easy to create, test, package and deploy the artifacts that can be uploaded to the SharePoint content database. This can be done in a fast and simple way without the need to create and deploy WSP packages. If we look at the above list of artifacts we can use SharePoint.DesignFactory.ContentFiles for master pages, page layouts, the style library, web part configurations, and initial publishing pages (these are normally made through the SharePoint web UI). Some artifacts like content types, fields and lists in the above list can NOT be handled by SharePoint.DesignFactory.ContentFiles, because they can’t be uploaded to the SharePoint content database. The good thing is that these artifacts are the artifacts that don’t change that much in the development of a SharePoint Publishing solution. There are however multiple ways to create these artifacts: Use paper script: create them manually in each of the environments based on documentation Automate the creation of the artifacts using (PowerShell) script Develop a WSP package to create these artifacts I’m not a big fan of the third option (see my blog post Thoughts on building deployable and updatable SharePoint solutions). It is a lot of work to create content types, fields and list definitions using all kind of XML files, and it is not allowed to modify these artifacts when in use. I know… SharePoint 2010 has some content type upgrade possibilities, but I think it is just too cumbersome. The first option has the problem that content types and fields get ID’s, and that these ID’s must be used by the metadata on for example page layouts. No problem for SharePoint.DesignFactory.ContentFiles, because it supports deploy-time resolving of these ID’s using PowerShell. For example consider the following metadata definition for the page layout contactpage-wcm.aspx.properties.ps1: Metadata page layout # This script must return a hashtable @{ name=value; ... } of field name-value pairs # for the content file that this script applies to. # On deployment to SharePoint, these values are written as fields in the corresponding list item (if any) # Note that fields must exist; they can be updated but not created or deleted. # This script is called right after the file is deployed to SharePoint.   # You can use the script parameters and arbitrary PowerShell code to interact with SharePoint. # e.g. to calculate properties and values at deployment time.   param([string]$SourcePath, [string]$RelativeUrl, $Context) @{     "ContentTypeId" = $Context.GetContentTypeID('GeneralPage');     "MasterPageDescription" = "Cloud Aviator Contact pagelayout (wcm - don't use)";     "PublishingHidden" = "1";     "PublishingAssociatedContentType" = $Context.GetAssociatedContentTypeInfo('GeneralPage') } The PowerShell functions GetContentTypeID and GetAssociatedContentTypeInfo can at deploy-time resolve the required information from the server we are deploying to. I personally prefer the second option: automate creation through PowerShell, because there are PowerShell scripts available to export content types and fields. An example project structure for a typical SharePoint WCM site looks like: Note that this project uses DualLayout. So if you build Publishing sites using SharePoint, checkout out the completely free SharePoint.DesignFactory.ContentFiles tooling and start flying!

  • Stream Media from Windows 7 to XP with VLC Media Player

    - by DigitalGeekery
    So you’ve got yourself a new computer with Windows 7 and you’re itching to take advantage of it’s ability to stream media across your home network. But, the rest of the family is still on Windows XP and you’re not quite ready to shell out the cash for the upgrades. Well, today we’ll show you how to easily stream media from Windows 7 to Windows XP with VLC Media Player. On the host computer running Windows 7, you’ll need to have an account set up with both a username and password. A blank password will not work. The media files will need to be located in a shared folder. Note: If the media files are located within the Public directory, or within the profile of the user account you use to log into the Windows 7 computer, they will be shared automatically. Sharing your Media Folders On your Windows 7 computer, right-click on the folder containing the files you’d like to stream and choose Properties.     On the Sharing Tab of the folder properties, click the Share button. Click OK.   Type or select from the drop down the user account you’ll use to log in, or select “Everyone” to share with all users. Then click Add. You may change the permission level, but only Read permission is required to play the media. Repeat this process for any additional folders you wish to share.    The Windows XP Client Computer Now that we’ve shared our media folders from the Windows 7 computer, we’re ready to play our files on the Windows XP computer. Download and install the VLC Media Player. (See link below) Then open VLC. Click on Media from the and select Open File… Browse your network for the shared folder that contains your media.   You’ll be prompted to log in to the host computer. Provide the credentials for a user on the Windows 7 computer. Click OK.   Select your media file and click Open.    Your media playback will begin momentarily.   This is a nice and easy way to stream media across your home network without upgrading multiple computers to Windows 7.  Plus, VLC is certainly no slouch as a Media Player. It’ll play virtually any video or audio file you can throw at it. Have you already upgraded all your home PCs to Windows 7?

  • BizTalk Cross Reference Data Management Strategy

    - by charlie.mott
    Article Source: http://geekswithblogs.net/charliemott This article describes an approach to the management of cross reference data for BizTalk.  Some articles about the BizTalk Cross Referencing features can be found here: http://home.comcast.net/~sdwoodgate/xrefseed.zip http://geekswithblogs.net/michaelstephenson/archive/2006/12/24/101995.aspx http://geekswithblogs.net/charliemott/archive/2009/04/20/value-vs.id-cross-referencing-in-biztalk.aspx Options Current options to managing this data include: Maintaining xml files in the format that can be used by the out-of-the-box BTSXRefImport.exe utility. Use of user interfaces that have been developed to manage this data: BizTalk Cross Referencing Tool XRef XML Creation Tool However, there are the following issues with the above options: The 'BizTalk Cross Referencing Tool' requires a separate database to manage.  The 'XRef XML Creation' tool has no means of persisting the data settings. The 'BizTalk Cross Referencing tool' generates integers in the common id field. I prefer to use a string (e.g. acme.country.uk). This is more readable. (see naming conventions below). Both UI tools continue to use BTSXRefImport.exe.  This utility replaces all xref data. This can be a problem in continuous integration environments that support multiple clients or BizTalk target instances.  If you upload the data for one client it would destroy the data for another client.  Yet in TFS where builds run concurrently, this would break unit tests. Alternative Approach In response to these issues, I instead use simple SQL scripts to directly populate the BizTalkMgmtDb xref tables combined with a data namepacing strategy to isolate client data. Naming Conventions All data keys use namespace prefixing.  The pattern will be <companyName>.<data Type>.  The naming conventions will be to use lower casing for all items.  The data must follow this pattern to isolate it from other company cross-reference data.  The table below shows some sample data. (Note: this data uses the 'ID' cross-reference tables.  the same principles apply for the 'value' cross-referencing tables). Table.Field Description Sample Data xref_AppType.appType Application Types acme.erp acme.portal acme.assetmanagement xref_AppInstance.appInstance Application Instances (each will have a corresponding application type). acme.dynamics.ax acme.dynamics.crm acme.sharepoint acme.maximo xref_IDXRef.idXRef Holds the cross reference data types. acme.taxcode acme.country xref_IDXRefData.CommonID Holds each cross reference type value used by the canonical schemas. acme.vatcode.exmpt acme.vatcode.std acme.country.usa acme.country.uk xref_IDXRefData.AppID This holds the value for each application instance and each xref type. GBP USD SQL Scripts The data to be stored in the BizTalkMgmtDb xref tables will be managed by SQL scripts stored in a database project in the visual studio solution. File(s) Description Build.cmd A sqlcmd script to deploy data by running the SQL scripts below.  (This can be run as part of the MSBuild process).   acme.purgexref.sql SQL script to clear acme.* data from the xref tables.  As such, this will not impact data for any other company. acme.applicationInstances.sql   SQL script to insert application type and application instance data.   acme.vatcode.sql acme.country.sql etc ...  There will be a separate SQL script to insert each cross-reference data type and application specific values for these types.

  • SQL SERVER – SOS_SCHEDULER_YIELD – Wait Type – Day 8 of 28

    - by pinaldave
    This is a very interesting wait type and quite often seen as one of the top wait types. Let us discuss this today. From Book On-Line: Occurs when a task voluntarily yields the scheduler for other tasks to execute. During this wait the task is waiting for its quantum to be renewed. SOS_SCHEDULER_YIELD Explanation: SQL Server has multiple threads, and the basic working methodology for SQL Server is that SQL Server does not let any “runnable” thread to starve. Now let us assume SQL Server OS is very busy running threads on all the scheduler. There are always new threads coming up which are ready to run (in other words, runnable). Thread management of the SQL Server is decided by SQL Server and not the operating system. SQL Server runs on non-preemptive mode most of the time, meaning the threads are co-operative and can let other threads to run from time to time by yielding itself. When any thread yields itself for another thread, it creates this wait. If there are more threads, it clearly indicates that the CPU is under pressure. You can fun the following DMV to see how many runnable task counts there are in your system. SELECT scheduler_id, current_tasks_count, runnable_tasks_count, work_queue_count, pending_disk_io_count FROM sys.dm_os_schedulers WHERE scheduler_id < 255 GO If you notice a two-digit number in runnable_tasks_count continuously for long time (not once in a while), you will know that there is CPU pressure. The two-digit number is usually considered as a bad thing; you can read the description of the above DMV over here. Additionally, there are several other counters (%Processor Time and other processor related counters), through which you can refer to so you can validate CPU pressure along with the method explained above. Reducing SOS_SCHEDULER_YIELD wait: This is the trickiest part of this procedure. As discussed, this particular wait type relates to CPU pressure. Increasing more CPU is the solution in simple terms; however, it is not easy to implement this solution. There are other things that you can consider when this wait type is very high. Here is the query where you can find the most expensive query related to CPU from the cache Note: The query that used lots of resources but is not cached will not be caught here. SELECT SUBSTRING(qt.TEXT, (qs.statement_start_offset/2)+1, ((CASE qs.statement_end_offset WHEN -1 THEN DATALENGTH(qt.TEXT) ELSE qs.statement_end_offset END - qs.statement_start_offset)/2)+1), qs.execution_count, qs.total_logical_reads, qs.last_logical_reads, qs.total_logical_writes, qs.last_logical_writes, qs.total_worker_time, qs.last_worker_time, qs.total_elapsed_time/1000000 total_elapsed_time_in_S, qs.last_elapsed_time/1000000 last_elapsed_time_in_S, qs.last_execution_time, qp.query_plan FROM sys.dm_exec_query_stats qs CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) qt CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) qp ORDER BY qs.total_worker_time DESC -- CPU time You can find the most expensive queries that are utilizing lots of CPU (from the cache) and you can tune them accordingly. Moreover, you can find the longest running query and attempt to tune them if there is any processor offending code. Additionally, pay attention to total_worker_time because if that is also consistently higher, then  the CPU under too much pressure. You can also check perfmon counters of compilations as they tend to use good amount of CPU. Index rebuild is also a CPU intensive process but we should consider that main cause for this query because that is indeed needed on high transactions OLTP system utilized to reduce fragmentations. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All of the discussions of Wait Stats in this blog is generic and varies from system to system. It is recommended that you test this on a development server before implementing it to a production server.

  • Windows Phone–A beautiful phone which I admire but I don’t recommend to friends and family

    - by Gopinath
    Microsoft’s Windows Phones are the most beautiful phones I’ve seen. Look at the photo which Microsoft shared on their Facebook page today. It’s gorgeous. Windows Phones come in vibrant colors and the user interface is very lively. When you keep an iPhone, Android Phone & a Windows Phone on a table, Windows Phone definitely stands out. Android and iOS interfaces are routine – a bunch of apps icons arranged in rows and multiple screens. Windows Phone is very different, the live tiles concept mesmerizes us. I love Windows Phone, but neither I buy one nor I recommend to family/friends! Why? Because it does not have all the Apps I need. Microsoft advertises that Windows Phone has 100K apps on its Windows Market Place. It’s true, there are 100K+ apps available for Windows Phone but not many of them are really useful and most of the popular Apps I use on Android are not available. When I say this to my friends at Microsoft, they don’t agree and one of them asked me list the apps that are not available. For him today I spent an hour quickly scanning through the apps installed on my Google Nexus and searched for same apps on Windows Market Place. As expected many of them are not available. Here is the list of my favorite Android apps that are not available for Windows Phone Mint – I use this app more than any of the Banking Apps I’ve installed on my mobile. It’s one app to keep a tab on all the expenses and income, the best money management and tracking app. Google Chrome – Web without Google Chrome is too boring, either on Desktop or on mobile. IE is too heavy and Firefox is loosing its grip. Chrome is the new darling of web. Pulse, Flipboard – Flipboard and Pulse are one of the best apps for reading news and following content of favorite blogs. Dropbox – Sync content across devices and provides access to your content on any device.It really does not matter what is your gadget – mobile, tablet or computer; Dropbox lets you access your content. GMail, Google Maps – Should I say how important are these two apps in our day to day life!! Vonage Extension – For around 30 bucks a month, Vonage provide landline service in USA + unlimited calls to India and many other countries + Vonage Extension App that lets Android/iOS mobile to make unlimited international calls for free. Without Vonage Extension app, I’m almost cutoff from my family and friends back home in India. Instagram – The most popular camera app used from a common man to celebrities. Raaga, Dhingana  – Music is part and parcel of life and these two apps are the most like popular apps to listen to Indian music. Quora – Quora is the place where most of the sensible discussions happen on web. Google Analytics, Google Adsense – I’m a blogger and these two apps mean a lot to me The list goes on and on! There are many useful apps that are not available on Windows Phone – TuneIn, MyTWC, Chrome To Phone, Google Voice, etc. Without all these apps, Windows Phone is just another old Nokia phone. Even though Windows Phone is the most beautiful phone, it needs Apps to attract customers. Without apps a smartphone is more or less a dumb feature phone which we loved to use before release of iPhone. Wish in an year or two the beautiful Windows Phone may have all the missing Apps. When it happens I’ll buy a phone for myself and recommend it to my family & friends. But till then I prefer to stay away.

  • Parallelism in .NET – Part 19, TaskContinuationOptions

    - by Reed
    My introduction to Task continuations demonstrates continuations on the Task class.  In addition, I’ve shown how continuations allow handling of multiple tasks in a clean, concise manner.  Continuations can also be used to handle exceptional situations using a clean, simple syntax. In addition to standard Task continuations , the Task class provides some options for filtering continuations automatically.  This is handled via the TaskContinationOptions enumeration, which provides hints to the TaskScheduler that it should only continue based on the operation of the antecedent task. This is especially useful when dealing with exceptions.  For example, we can extend the sample from our earlier continuation discussion to include support for handling exceptions thrown by the Factorize method: // Get a copy of the UI-thread task scheduler up front to use later var uiScheduler = TaskScheduler.FromCurrentSynchronizationContext(); // Start our task var factorize = Task.Factory.StartNew( () => { int primeFactor1 = 0; int primeFactor2 = 0; bool result = Factorize(10298312, ref primeFactor1, ref primeFactor2); return new { Result = result, Factor1 = primeFactor1, Factor2 = primeFactor2 }; }); // When we succeed, report the results to the UI factorize.ContinueWith(task => textBox1.Text = string.Format("{0}/{1} [Succeeded {2}]", task.Result.Factor1, task.Result.Factor2, task.Result.Result), CancellationToken.None, TaskContinuationOptions.NotOnFaulted, uiScheduler); // When we have an exception, report it factorize.ContinueWith(task => textBox1.Text = string.Format("Error: {0}", task.Exception.Message), CancellationToken.None, TaskContinuationOptions.OnlyOnFaulted, uiScheduler); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The above code works by using a combination of features.  First, we schedule our task, the same way as in the previous example.  However, in this case, we use a different overload of Task.ContinueWith which allows us to specify both a specific TaskScheduler (in order to have your continuation run on the UI’s synchronization context) as well as a TaskContinuationOption.  In the first continuation, we tell the continuation that we only want it to run when there was not an exception by specifying TaskContinuationOptions.NotOnFaulted.  When our factorize task completes successfully, this continuation will automatically run on the UI thread, and provide the appropriate feedback. However, if the factorize task has an exception – for example, if the Factorize method throws an exception due to an improper input value, the second continuation will run.  This occurs due to the specification of TaskContinuationOptions.OnlyOnFaulted in the options.  In this case, we’ll report the error received to the user. We can use TaskContinuationOptions to filter our continuations by whether or not an exception occurred and whether or not a task was cancelled.  This allows us to handle many situations, and is especially useful when trying to maintain a valid application state without ever blocking the user interface.  The same concepts can be extended even further, and allow you to chain together many tasks based on the success of the previous ones.  Continuations can even be used to create a state machine with full error handling, all without blocking the user interface thread.

  • Framework 4 Features: Support for Timed Jobs

    - by Anthony Shorten
    One of the new features of the Oracle Utilities Application Framework V4 is the ability for the batch framework to support Timed Batch. Traditionally batch is associated with set processing in the background in a fixed time frame. For example, billing customers. Over the last few versions their has been functionality required by the products required a more monitoring style batch process. The monitor is a batch process that looks for specific business events based upon record status or other pieces of data. For example, the framework contains a fact monitor (F1-FCTRN) that can be configured to look for specific status's or other conditions. The batch process then uses the instructions on the object to determine what to do. To support monitor style processing, you need to run the process regularly a number of times a day (for example, every ten minutes). Traditional batch could support this but it was not as optimal as expected (if you are a site using the old Workflow subsystem, you understand what I mean). The Batch framework was extended to add additional facilities to support times (and continuous batch which is another new feature for another blog entry). The new facilities include: The batch control now defines the job as Timed or Not Timed. Non-Timed batch are traditional batch jobs. The timer interval (the interval between executions) can be specified The timer can be made active or inactive. Only active timers are executed. Setting the Timer Active to inactive will stop the job at the next time interval. Setting the Timer Active to Active will start the execution of the timed job. You can specify the credentials, language to view the messages and an email address to send the a summary of the execution to. The email address is optional and requires an email server to be specified in the relevant feature configuration. You can specify the thread limits and commit intervals to be sued for the multiple executions. Once a timer job is defined it will be executed automatically by the Business Application Server process if the DEFAULT threadpool is active. This threadpool can be started using the online batch daemon (for non-production) or externally using the threadpoolworker utility. At that time any batch process with the Timer Active set to Active and Batch Control Type of Timed will begin executing. As Timed jobs are executed automatically then they do not appear in any external schedule or are managed by an external scheduler (except via the DEFAULT threadpool itself of course). Now, if the job has no work to do as the timer interval is being reached then that instance of the job is stopped and the next instance started at the timer interval. If there is still work to complete when the interval interval is reached, the instance will continue processing till the work is complete, then the instance will be stopped and the next instance scheduled for the next timer interval. One of the key ways of optimizing this processing is to set the timer interval correctly for the expected workload. This is an interesting new feature of the batch framework and we anticipate it will come in handy for specific business situations with the monitor processes.

  • MongoDB usage best practices

    - by andresv
    The project I'm working on uses MongoDB for some stuff so I'm creating some documents to help developers speedup the learning curve and also avoid mistakes and help them write clean & reliable code. This is my first version of it, so I'm pretty sure I will be adding more stuff to it, so stay tuned! C# Official driver notes The 10gen official MongoDB driver should always be referenced in projects by using NUGET. Do not manually download and reference assemblies in any project. C# driver quickstart guide: http://www.mongodb.org/display/DOCS/CSharp+Driver+Quickstart Reference links C# Language Center: http://www.mongodb.org/display/DOCS/CSharp+Language+Center MongoDB Server Documentation: http://www.mongodb.org/display/DOCS/Home MongoDB Server Downloads: http://www.mongodb.org/downloads MongoDB client drivers download: http://www.mongodb.org/display/DOCS/Drivers MongoDB Community content: http://www.mongodb.org/display/DOCS/CSharp+Community+Projects Tutorials Tutorial MongoDB con ASP.NET MVC - Ejemplo Práctico (Spanish):http://geeks.ms/blogs/gperez/archive/2011/12/02/tutorial-mongodb-con-asp-net-mvc-ejemplo-pr-225-ctico.aspx MongoDB and C#:http://www.codeproject.com/Articles/87757/MongoDB-and-C C# driver LINQ tutorial:http://www.mongodb.org/display/DOCS/CSharp+Driver+LINQ+Tutorial C# driver reference: http://www.mongodb.org/display/DOCS/CSharp+Driver+Tutorial Safe Mode Connection The C# driver supports two connection modes: safe and unsafe. Safe connection mode (only applies to methods that modify data in a database like Inserts, Deletes and Updates. While the current driver defaults to unsafe mode (safeMode == false) it's recommended to always enable safe mode, and force unsafe mode on specific things we know aren't critical. When safe mode is enabled, the driver internal code calls the MongoDB "getLastError" function to ensure the last operation is completed before returning control the the caller. For more information on using safe mode and their implicancies on performance and data reliability see: http://www.mongodb.org/display/DOCS/getLastError+Command If safe mode is not enabled, all data modification calls to the database are executed asynchronously (fire & forget) without waiting for the result of the operation. This mode could be useful for creating / updating non-critical data like performance counters, usage logging and so on. It's important to know that not using safe mode implies that data loss can occur without any notification to the caller. As with any wait operation, enabling safe mode also implies dealing with timeouts. For more information about C# driver safe mode configuration see: http://www.mongodb.org/display/DOCS/CSharp+getLastError+and+SafeMode The safe mode configuration can be specified at different levels: Connection string: mongodb://hostname/?safe=true Database: when obtaining a database instance using the server.GetDatabase(name, safeMode) method Collection: when obtaining a collection instance using the database.GetCollection(name, safeMode) method Operation: for example, when executing the collection.Insert(document, safeMode) method Some useful SafeMode article: http://stackoverflow.com/questions/4604868/mongodb-c-sharp-safemode-official-driver Exception Handling The driver ensures that an exception will be thrown in case of something going wrong, in case of using safe mode (as said above, when not using safe mode no exception will be thrown no matter what the outcome of the operation is). As explained here https://groups.google.com/forum/?fromgroups#!topic/mongodb-user/mS6jIq5FUiM there is no need to check for any returned value from a driver method inserting data. With updates the situation is similar to any other relational database: if an update command doesn't affect any records, the call will suceed anyway (no exception thrown) and you manually have to check for something like "records affected". For MongoDB, an Update operation will return an instance of the "SafeModeResult" class, and you can verify the "DocumentsAffected" property to ensure the intended document was indeed updated. Note: Please remember that an Update method might return a null instance instead of an "SafeModeResult" instance when safe mode is not enabled.

  • Change a File Type’s Icon in Windows 7

    - by Trevor Bekolay
    In Windows XP, you could change the icon associated with a file type in Windows Explorer. In Windows 7, you have to do some registry hacking to change a file type’s icon. We’ll show you a much easier and faster method for Windows 7. File Types Manager File Types Manager is a great little utility from NirSoft that includes the functionality of Windows XP’s folder options and adds a whole lot more. It works great in Windows 7, and its interface makes it easy to change a bunch of related file types at once. A common problem we run into are icons that look too similar. You have to look for a few seconds to see the difference between the movies and the text files. Let’s change the icon for the movie files to make visually scanning through directories much easier. Open up File Types Manager. Find the “Default Icon” column and click on it to sort the list by the Default Icon. (We’ve hidden a bunch of columns we don’t need, so you may find it to be farther to the right.) This groups together all file extensions that already have the same icon. This is convenient because we want to change the icon of all video files, which at the moment all have the same default icon. Click the “Find” button on the toolbar, of press Ctrl+F. Type in a file type that you want to change. Note that all of the extensions with the same default icon are grouped together. Right click on the first extension whose icon you want to change and click on Edit Selected File Type, or select the first extension and press F2. Click the “…” button next to the Default Icon text field. Click on the Browse… button. File Types Manager allows you to select .exe, .dll, or .ico files. In our case, we have a .ico file that we took from the wonderful public domain Tango icon library. Select the appropriate icon (if you’re using a .exe or .dll there could be many possible icons) then click OK. Repeat this process for each extension whose icon you would like to change. Now it’s much easier to see at a glance which files are movies and which are text files! Of course, this process will work for any file type, so customize your files’ icons as you see fit.

  • Web Services for Info Explorer Zones

    - by Anthony Shorten
    One of the most interesting uses for XAI and Configurable objects is the exposure of a query portal as a Web Service. Let me illustrate this with an example. Say you have an interface that requires a list of data from a number of product tables. In the past you would have to build a java program to do this with SQL then use an application service but it is now possible with just configuration. The first step in the process is to create the SQL you want to use for the interface. It can be any valid static SQL or use host variables for the WHERE clause (we call that filtered). Once you are happy with the SQL (and it performs acceptably) you can incorporate that SQL into a Info-Explorer Zone. You can use any of the explorer zone types but I typically recommend F1-DE-SINGLE as it supports a single SQL statement with multiple filters (up to 15) as well as hidden filters (up to 5). Hidden filters are typically not displayed in the UI for criteria (remember explorer zones can be used on the user Interface as well) but for web services they can be used as normal filters (this means you can use up to 20 filters all up). Once you are happy with the zone, you now need to define it as a Business Service. We have a generic service called FWLZDEXP which allows a explorer zone to be defined as a Business Service. If you open any Business Service based upon FWLZDEXP you will see some examples. The schema is standard and pretty self explanatory in terms of the structure. The schema pattern looks like this: Zone element - maps to the ZONE_CD element and the default value is the zone name you just created. This links the business service to the zone. Filter elements - You name the filters as you like but the mapField is set to Fx_VALUE where x is the filter number corresponding to the filter element in the zone definition. Hidden filter elements - You name the filters as you like but the mapField is set to Hx_VALUE where x is the filter number corresponding to the hidden filter element in the zone definition. results group - this holds the elements of the result set. Each element in your result set has a tagname and is linked to the COL_VALUE mapField and the row element is lists the SEQNO of the column. This corresponds to the column number in the results set in the zone. An example schema is shown below for the F1-USGRACML zone, which returns the access modes for a user group and application service filters. In the example, the userGroup and applicationService elements are the filters and the rows would contain a list of accessModeDescr. This is just a simple example to illustrate the point. There are lots of examples in the product that you can investigate. One recommendation, to save time, is that you copy the schema from one of the examples to save you typing it from scratch. You can simply modify the tags and other elements to suit your needs. Once the Business Service is defined it can simply be defined as a Web Service by registering an XAI Inbound Service using the Business Service definition as a basis. You now have a Web Service based upon a Info Explorer Zone. This is one of my favorite components as it allows interfaces to be simplified. This will be my last blog entry for this year. I hope you all have a great and safe Christmas and an even greater new year. Next year promises to be an exciting year and I look forward to communicating exciting developments we are working on at the moment as they are released.

  • Software development stack 2012

    A couple of months ago, I posted on Google+ about my evaluation period for a new software development stack in general. "Analysing existing 'jungle' of multiple applications and tools in various languages for clarification and future design decisions. Great fun and lots of headaches... #DevelopersLife" Surprisingly, there was response... ;-) - And this series of articles is initiated by this post. Thanks Olaf. The past few years... Well, after all my first choice of software development in the past was Microsoft Visual FoxPro 6.0 - 9.0 in combination with Microsoft SQL Server 2000 - 2008 and Crystal Reports 9.x - XI. Honestly, it is my main working environment due to exisiting maintenance and support plans with my customers, but also for new project requests. And... hands on, it is still my first choice for data manipulation and migration options. But the earth is spinning, and as a software craftsman one has to be flexible with the choice of tools. In parallel to my knowledge and expertise in the above mentioned tools, I already started very early to get my hands dirty with the Microsoft .NET Framework. If I remember correctly, I started back in 2002/2003 with the first version ever. But this was more out of curiousity. During the years this kind of development got more serious and demanding, and I focused myself on interop and integrational libraries and applications. Mainly, to expose exisitng features of the .NET Framework to Visual FoxPro - I even had a session about that at the German Developer's Conference in Frankfurt. Observation of recent developments With the recent hype on Javascript and HTML5, especially for Windows 8 and Windows Phone 8 development, I had several 'Deja vu' events... Back in early 2006 (roughly) I had a conversation on the future of Web and Desktop development with my former colleagues Golo Roden and Thomas Wilting about the underestimation of Javascript and its root as a prototype-based, dynamic, full-featured programming language. During this talk with them I took the Mozilla applications, namely Firefox and Thunderbird, as a reference which are mainly based on XML, CSS, Javascript and images - besides the core rendering engine. And that it is very simple to write your own extensions for the Gecko rendering engine. Looking at the Windows Vista Sidebar widgets, just underlines this kind of usage. So, yes the 'Modern UI' of Windows 8 based on HTML5, CSS3 and Javascript didn't come as any surprise to me. Just allow me to ask why did it take so long for Microsoft to come up with this step? A new set of tools Ok, coming from web development in HTML 4, CSS and Javascript prior to Visual FoxPro, I am partly going back to that combination of technologies. What is the other part of the software development stack here at IOS Indian Ocean Software Ltd? Frankly, it is easy and straight forward to describe: Microsoft Visual FoxPro 9.0 SP 2 - still going strong! Visual Studio 2012 (C# on latest .NET Framework) MonoDevelop Telerik DevCraft Suite WPF ASP.NET MVC Windows 8 Kendo UI OpenAccess ORM Reporting JustCode CODE Framework by EPS Software MonoTouch and Mono for Android Subversion and additional tools for the daily routine: Notepad++, JustCode, SQL Compare, DiffMerge, VMware, etc. Following the principles of Clean Code Developer and the Agile Manifesto Actually, nothing special about this combination but rather a solid fundament to work with and create line of business applications for customers.Honestly, I am really interested in your choice of 'weapons' for software development, and hopefully there might be some nice conversations in the comment section. Over the next coming days/weeks I'm going to describe a little bit more in detail about the reasons for my decision. Articles will be added bit by bit here as reference, too. Please bear with me... Regards, JoKi

  • Manage Your WordPress Blog Comments from Your Windows Desktop

    - by Matthew Guay
    Are you never more than a few steps away from your PC and want to keep up with comments on your blog?  Then here’s how you can stay on top of your WordPress comments right from your desktop. Wp-comment-notifier is a small free app for Windows that lets you easily view, approve, reply to, and delete comments from your WordPress blog.  Whether you have a free WordPress.com blog or are running WordPress on your own server, this tool can keep you connected to your comments.  Unfortunately it only lets you manage comments at one blog, so if manage multiple WordPress-powered sites you may find this a downside.  Otherwise, it works great and helps you stay on top of the conversation at your blog. Get notified with wp-comment-notifier Download the wp-comment-notifier (link below) and install as usual. Run it once it’s installed.  Enter your blog address, username, and password when prompted. Wp-comment-notifier will automatically setup your account and download recent comments. Finally, enter your blog’s name, and click Finish. Review Comments with wp-comment-notifier You can now review your comments directly by double-clicking the new WordPress icon in your system tray.  The window has 3 tabs…comments, pending, and spam.  Select a comment to reply, edit, spam, or delete it directly from your desktop. If you select Edit, then you can edit the HTML of the comment (including links) directly from within the notifier. You can approve or permanently delete any spam messages that are caught by your blog’s spam filter. Whenever new comments come in, you’ll see a tray popup letting you know how many comments are waiting to be approved or are in the spam folder.  Click the popup to open the editor. Now, you can directly approve that pending comment without going to your WordPress admin page.  When you’re done, just press Enter on your Keyboard to post the reply. Or, if you want to reply to the comment, click the reply link and enter your comment in the entry box at the bottom. If you ever want to double-check if there’s any new comments, just right-click on the tray icon and select refresh. Finally, you can change the settings from the Configuration link in the tray button or by clicking the gear button on the bottom of the review window.  You can change how often it checks for new comments, not to start the notifier at system startup, and edit your account information. Conclusion Whether you’re managing your personal blog or administer a site with millions of hits per day, staying on top of the conversation is one of the best ways to build and maintain your audience.  With wp-comment-notifier, you can be sure that you’re always in control of your blogs comments.  This app is especially useful if you review all comments before allowing them to be published.

  • Oracle BI and XS Energy Drinks – Don’t Miss the Amway Presentation!

    - by Michelle Kimihira
    By Maria Forney Amway is a global leader in the direct sales industry with $10.9B in annual sales in more than 100 countries and territories. The company has implemented a global BI framework that provides accurate, consistent, and timely insights to support global, regional and local analytical research, business planning, performance measurement and assessment. Oracle BI EE is used by 1500 employees across Amway sales, marketing, finance, and supply chain business units as well as Amway affiliates in Europe, Russia, South Africa, Japan, Australia, Latin America, Malaysia, Vietnam, and Indonesia. Last week, I spoke with Lead Data Analyst with Amway Global Sales, Dan Arganbright, and IT Manager with Amway BI Competency Center, Mike Olson, about their upcoming presentation at Oracle OpenWorld in San Francisco. Scheduled during a prime speaking slot on Monday, October 1 at 12:15pm in Moscone West, 2007, Dan and Mike will discuss their experience building Amway’s Distributor Consulting solution, powered by Oracle BI EE. You can find more information here. As background, Amway offers people an opportunity to own their own businesses and consumers exclusive products in health and wellness, beauty and home care.  The Amway internal Sales organization is charged with consulting leadership-level Distributors to help them with data insights and ultimately grow their business. Until recently, this was a resource-intense process of gathering and formatting data. In some markets, it took over 40 hours to collect the data and produce the analysis needed for one consultation session. Amway began its global BI journey in 2006 and since then the company has migrated from having multiple technology providers and integration points to an integrated strategic vendor approach. Today, the company has standardized on Oracle technology for BI.  Amway has achieved cost savings through the retirement of redundant technology platforms. In addition, Mike’s organization has led the charge to align disparate BI organizations into a BI Competency Center.  The following diagram highlights the simplicity of the standardized architecture of Amway today. Dubbed Distributor Consulting, Amway has developed a BI solution using the Oracle technology stack to help Distributor leaders grow their businesses. The Distributor Consulting solution provides over 40 metrics for Sales staff to provide data-driven insights on the Distributors and organizations they support.  Using Oracle BI EE, Exadata, and Oracle Data Integrator, Amway provides customized and personalized business intelligence, and the Oracle BI EE dashboards were developed by the Amway Sales organization, which demonstrates business empowerment of the technology. Amway is also leveraging the power of BI to drive business growth in all of its markets.  A new set of Distributor Segmentation metrics are enabling a better understanding of distributor behaviors. A Global Scorecard that Amway developed provides key metrics at a market and global level for executive-level discussions. Product Analysis teams can now highlight repeat purchase rates, product penetration and the success of CRM campaigns. In the words of Dan and Mike, the addition of Exadata 11 months ago has been “a game changer.”  Amway has been able to dramatically reduce complexity, improve performance and increase business productivity and cost savings. For example, the number of indexes on the global data warehouse was reduced from more than 1,000 to less than 20.  Pulling data for the highest level distributors or the largest markets in the company now can be done in minutes instead of hours.  As a result, IT has shifted from performance tuning and keeping the system operational to higher-value business-focused activities. •       “The distributors that have been introduced to the BI reports have found them extremely helpful. Because they have never had this kind of information before, when they were presented with the reports, they wanted to take action immediately!”  -     Sales Development Manager in Latin America Without giving away more, the Amway case study presentation will be one of the unique customer sessions at OpenWorld this year. Speakers Dan Arganbright and Mike Olson have planned an interactive and entertaining session on Monday October 1 at 12:15pm in Moscone West, 2007. I’ll see you there!

  • 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.

  • Juju stuck in "pending" state when using LXC

    So I'm trying to get started with Juju, and tried to do this locally using LXC. I followed the instructions here: How do I configure juju for local usage? Unfortunately this doesn't seem to work for me. status shows the following: $ juju status machines: 0: agent-state: running dns-name: localhost instance-id: local instance-state: running services: mysql: charm: cs:precise/mysql-1 relations: db: - wordpress units: mysql/0: agent-state: pending machine: 0 public-address: null wordpress: charm: cs:precise/wordpress-0 exposed: true relations: db: - mysql units: wordpress/0: agent-state: pending machine: 0 open-ports: [] public-address: null 2012-05-10 14:09:38,155 INFO 'status' command finished successfully As you can see the agent-state is 'pending' and there is no public address where I'm able to access the newly created site.

  • 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.
