• How can I troubleshoot flash player/hardware conflict?

  - by sparthikas

  OBJECTIVE: Have a web browser on my Ubuntu install that can play youtube and hulu videos. Also would like to understand problem so that I can fix it again if I change software. Workarounds welcome, technical understanding and solution preferable. SYMPTOMS: Flash does not run - cannot make the right-click menu appear, an empty box is where video should be, changes to black box when hovering over other links. The "The Adobe Flash plugin has crashed" message does not appear with its sad lego face. cannot activate proprietary graphics driver - causes system to reboot to a prompt. SOLUTIONS TRIED: Replaced OS (tried slackware 13.37, fedora 17, linuxmint 13 maya, gentoo, lubuntu, and even winXP. lubuntu confirmed to work, don't remember how much tweaking, if any, this required. Slack, fedora, mint, and gentoo all failed to run flash just like ubuntu) many reinstalls of flash player via different methods, including cleaning up old installs first, also tried gnash and lightspark. replaced graphics card (replaced HIS IceQ Radeon HD 4670 AGP with older GeForce 5700 LE no change in problem) flash does successfully work on winXP installation with Catalyst AGP hotfix driver applied, however I consider windows wholly unacceptable for web browsing due to lack of security. Lubuntu install also works, however I do not want to be tied down to just using Lubuntu on this computer. SYSINFO: Have latest versions of Ubuntu, Firefox, and Flash on fresh Ubuntu install. Using Gigabyte 7s748 motherboard with Athlon XP 2800+ and 3 GB of RAM with Radeon HD 4670 AGP card, also a Dell soundblaster live series sound card (due to malfunction of onboard sound on motherboard) Wired internet connection, Maxtor 6Y120L3 HDD, Sony DVD RW AW-Q170A, Dell M993s monitor. NOTES: I do not know if the graphics driver issue and the flash troubles are linked. Substitution of older graphics card having same flash troubles seems to suggest they aren't. My troubleshooting method is rather reductionist, consisting mainly of "replace things until you find out what was causing the error by process of elimination" only it seems that this must be a conflict which arises when software decides how to configure itself on my hardware. That is, I know the hardware can run Flash, and I know that on other systems the same software can too, but somehow the combination fails. Consequently I feel out of my depth. I will keep trying things off and on, but I have spent probably about 30 man-hours in the last 4 months working on this problem with no joy other than the lubuntu workaround. Any help will be appreciated, I will be checking back and posting updates.

• Control Sysinternals Suite & NirSoft Utilities with a Single Interface

  - by Asian Angel

  Sysinternals and NirSoft both provide helpful utilities for your Windows system but may not be very convenient to access. Using the Windows System Control Center you can easily access everything through a single UI front end. Setup The first thing to do is set up three new folders in Program Files (or Program Files (x86) if you are using a 64bit system) with the following names (the first two need to exactly match what is shown here): Sysinternals Suite NirSoft Utilities (create this folder only if you have any of these apps downloaded) Windows System Control Center (or WSCC depending on your preferences) Unzip the contents of the Sysinternals Suite into its’ folder. Then unzip any individual NirSoft Utilities programs that you have downloaded into the NirSoft folder. All that is left to do is to unzip the WSCC software into its’ folder and create a shortcut. WSCC in Action When you start WSCC up for the first time you will see the following message with a brief explanation about the software. Next the options window will appear providing you an opportunity to look around and make any desired changes. WSCC can access utilities for both suites using a live connection if needed (utilities accessed live are not downloaded). Note: This occurs on the first run only. This is the main WSCC window…you can choose the utility that you want to use by sorting through an all items list or based on category. Note: WSCC may occasionally experience a problem downloading a particular utility if using the live service. We conducted a quick test by accessing two Sysinternals apps. First PsInfo… Followed by DiskView. Both opened quickly and were ready to go. There were no NirSoft Utilities installed on our test system in order to provide a live access example. Within moments WSCC accessed the CurrProcess utility and had it running on our system. Our recommendation is to download your favorite utilities from both suites (in order to always have easy access to them). Conclusion WSCC provides an easy way to access all of the apps in the Sysinternals Suite and NirSoft Utilities in one place. Note: A PortableApps version is also available.

• Change default language settings in Visual Studio 2012

  - by sreejukg

  The first thing you need to do after the installation of Visual Studio 2012 is to choose the IDE preferences. Once you select your preferred collection of settings, the IDE will always choose dialogs and other options according to your selection. Nowadays developer’s needs to work with different programming environments and due to this, developers might need to reset the default settings. In this article, I am going to demonstrate how you can change the default settings in Visual Studio 2012. For the purpose of this demonstration, I have installed Visual Studio 2012 and selected C++ as my default environment settings. So now when I go to file -> new project, it will give me C++ templates by default as follows. If you want to select another language, you need to expand Other Languages section and select C# or VB. Now I am going to change these default settings. I am going to change the default language preference to C#. In Visual Studio 2012, go to tools menu and select Import and Export Settings. Here you have 3 options; one is to export the current settings so that the settings are saved for future use. Also you can import previously saved settings. The last option available is to reset it to default. It is a good Idea to export your settings and import it as you need in later stages. To reset the settings to default select the Reset option and click next. Now Visual Studio will ask you to whether you would like to save the settings, which can be used in future to restore. Select any one option and click next. For the purpose of this demo, I have selected not to save the settings. Click Next button to continue. Now Visual Studio will bring you the similar dialog that appears just after installation to select your IDE settings. Select the required settings from the available list and click Finish button. Click Finish once you are done. If everything OK, you will see the success message as below. Now go to file -> new Project, you will see the selected language appear by default. I selected C# in the previous step and the new project dialog appears as follows. Changing IDE settings in Visual Studio 2012 is very easy and straight forward.

• Enable Thumbnail Previews for Firefox in Windows 7 Taskbar

  - by Asian Angel

  Are you tired of waiting for the official activation of Taskbar Thumbnail Previews in Firefox? See how easy it is to enable them now with a simple about:config hack. Note: We have briefly covered this before but present it here in a more detailed format. Before For our example we opened all of the websites in the HTG Network in tabs… When hovering over the Firefox Icon in the Taskbar, you only see the one thumbnail. There are two things in particular to notice here: 1.) The Tab Bar for Firefox is displayed with all four tabs visible in the Thumbnail Preview  2.) The “Taskbar Icon” itself is displaying as singular with no “fanned edge” on the right side. Hack the About:Config Settings To get the Thumbnail Previews working you will need to make a modification in the about:config settings. Type about:config in the Address Bar and press Enter. Unless you have previously disabled the warning you will see this message after pressing Enter. Click on the I promise! Button to finish entering the settings. In the Filter Address Bar either type or copy and paste the following about:config entry: browser.taskbar.previews.enable After you enter that in, you should see the entry listing as shown here. At this point there are two methods that you can choose to alter the entry. The first method is to right click on the entry and select Toggle and the second method is to double click on the entry. Both work equally well…choose the method that you like best. Once the about:config entry has been changed, you will need to restart Firefox for it to take effect. After restarting Firefox on our system the Thumbnail Previews were definitely looking very nice. Notice that the Tab Bar is no longer displayed in the Thumbnail Previews. The Taskbar Icon also had a “fanned edge” indicating that multiple tabs were open. Conclusion If you are tired of waiting for Mozilla to officially activate Taskbar Thumbnail Previews in Firefox, then you can go ahead and start enjoying them now.

• The 2010 Life Insurance Conference - Washington, DC

  - by [email protected]

  How ironic to be in Washington, DC on April 15 - TAX DAY! Fortunately, I avoided IRS offices and attended the much more enjoyable 2010 Life Insurance Conference, presented by LIMRA, LOMA SOA and ACLI. This year's conference offered a variety of tracks focused on the Life Industry including Distribution/Marketing Marketing, Administration, Actuarial/Product Development, Regulatory, Reinsurance and Strategic Management. President and CEO of the ACLI, Frank Keating, opened the event by moderating a session titled "Executive Viewpoint on new Opportunities." Guest speakers included Ted Mathas, President and CEO of NY Life, and John Walters, President and CEO of Hartford Life. Both speakers were insightful as they shared the challenges and opportunities each company faces and the key role life insurance companies play in our society and the global economy. There were several key themes that were reiterated in multiple sessions throughout the conference - the economy is on the rebound, optimism is growing, consumer spending is up and an uptick in employment is likely to follow. The threat of a double dip recession has seemed to passed. Good news for our industry, and welcomed by all in attendance. Of special interest to me, given my background, was some research shared by both The Nolan Group and Novarica in separate sessions. Both firms indicate that policy administration upgrades/replacement projects remain a top priority in 2010. Carriers continue to invest in modern technology. Modern ultra-configurable systems enable carriers to switch from a waterfall to an agile project methodology, which often entails a "culture change" within an organization. Other themes heard throughout the two-day event: Virtually all sessions focused on People, Process and Technology! Product innovation, agility and speed to market are as important as ever. Social Networks and Twitter are becoming more popular ways of communicating with both field and dispersed staff. Several sessions focused on the application, new business and underwriting process. Companies continue looking for ways to increase market agility, accelerate speed to market, address cost issues and improve service levels across the process. They recognize the need to ease the way to do business with both producers and consumers. Author and economic futurist Jeff Thredgold presented an entertaining, informative and humorous general session on Wednesday afternoon that focused on the US and global economies, financial markets and retirement outlook. Thredgold did not disappoint anyone with his message! The Thursday morning general session was keynoted by Therese Vaughan (CEO - NAIC) and Thomas Crawford (President of C2 Group). Both speakers gave a poignant view of the recent financial crisis and discussed "Putting the Pieces Back Together." Therese spoke of the recent financial turmoil and likely changes to regulations to the financial services sector. Tom's topics focused on economic recovery and the political environment in Washington, and how that impacts our industry. Next year's event will be April 11-13, 2011 in Las Vegas. Roger A.Soppe, CLU, LUTCF, is the Senior Director of Insurance Strategy, Oracle Insurance.

• 10.10 freezing when sftp downloading

  - by aGr

  My ubuntu 10.10 is freezing during downloading from my other computer on sftp. I thought it might be some nautilus issues so I tried it via command line and I got the same thing - after few minutes the whole computer freezes. Mostly the numlock led is blinking (I've heard somewhere that this means a kernel panic), but not in 100% cases.

• Music before bells and whistles

  - by Tony Davis

  Why is it that Windows has so much difficulty in finding content on its file system? This is not an insurmountable technical problem; on my laptop, I have a database within which I can instantly find text or names within millions of records, within 300 milliseconds. I have a copy of Google Desktop that can find phrases within emails or documents, almost as quickly. It is an important, though mundane, part of an operating system to be able to find files. The first thing I notice within Windows is that the facility to find files or text within files is called 'search' rather than 'find'. Hmm. This doesn’t bode well. What’s this? It does a brute-force search for file names? Here we are in an age when we can breed mice that glow in the dark, and manufacture computers that fit in our shirt pockets, and we find an operating system that is still entirely innocent of managing and indexing content in hierarchical data. I can actually read the files of my PC into a database, mimic the directory/folder hierarchies and then find files in a flash; but when I do the same with Windows Vista, we are suddenly back in a 1960s time warp. Finding files based on their name is bad enough, but finding files based on the content that they contain is more or less asking for an opportunity to wait 20 minutes in order to see a "file not found" message. Sadly, with Windows 7, Microsoft seems to have fallen into the familiar trap of adding bells and whistles before finishing the song. It's certainly true that Microsoft has added new features and a certain polish to Windows Search 4.0, the latest incarnation. It works more like a web search and offers a new search syntax, called Advanced Query Syntax, which allows you to search on file author, file size, date ranges (e.g. date:=7/4/09still does not work reliably. I've experienced first-hand its stubborn refusal, despite a full index, to acknowledge the existence of a file I know exists, based on a search for a specific term within that file that I know is in there somewhere; a file that Google Desktop search, or old wingrep, finds in seconds. When users hark back to the halcyon days of Windows XP search, you know something is seriously amiss. Shouldn't applications get the functionality right before applying animated menus and Teletubby graphics, or is advancing age making me grumpy? I’d be pleased to hear your views, as always. Cheers, Tony.

• Ranking Part III

  - by PointsToShare

  © 2011 By: Dov Trietsch. All rights reserved   Ranking Part III In a previous blogs “Ranking an Introduction” and  “Ranking Part II” , you have already praised me in “Rank the Author” and learned how to create a new element on a page and how to place it where you need it. For this installment, I just added code to keep the number of votes (you vote by clicking one of the stars) and the total vote. Using these two, we can compute the average rating. It’s a small step, but its purpose is to show that we do not need a detailed history in order to compute the average. A running total is sufficient. Please note that once you close the game, you will lose your previous total. In real life, we persist the totals in the list itself. We also keep a list of actual votes, but its purpose is to prevent double votes. If a person has already voted, his user id is already on the list and our program will check for it and bar the person from voting again. This is coded in an event receiver, which is a SharePoint server piece of code. I will show you how to do this part in a subsequent blog. Again, go to the page and look at the code. The gist of it is here. avg, votes, and stars are global variables that I defined before. function sendRate(sel){//I hate long line so I created pieces of the message in their own vars            var s1 = "Your Rating Was: ";            var s2 = ".. ";            var s3 = "\nVotes = ";            var s4 = "\nTotal Stars = ";            var s5 = "\nAverage = ";            var s;            s = parseInt(sel.id.replace("_", '')); // Get the selected star number            votes = parseInt(votes) + 1;            stars = parseInt(stars) + s;            avg = parseFloat(stars) / parseFloat(votes);            alert(s1 + sel.id + s2 +sel.title + s3 + votes + s4 + stars + s5 + avg);} Click on the link to play and examine “Ranking with Stats” That’s all folks!

• Issues with timed out downloads via TomCat?

  - by Ira Baxter

  We get, in our opinion, a lot of failed download attempts and want to understand why. We offer downloads via an email link (typical): http://www.semanticdesigns.com/deliverEval/<productname> This is processed by Tomcat on Linux via a jsp file, with the following code: response.addHeader( "Content-Disposition", "attachment; filename=" + fileTail ); response.addHeader( "Content-Type", "application/x-msdos-program" ); byte[] buf = new byte[8192]; int read; try { java.io.FileInputStream input = new java.io.FileInputStream( filename ); java.io.OutputStream o = response.getOutputStream(); while( ( read = input.read( buf, 0, 8192 ) ) != -1 ){ o.write( buf, 0, read ); } o.flush(); } catch( Exception e ){ util.fatalError( request.getRequestURI(), "Error sending file '" + filename + "' to client", e ); throw e; } We get a lot of reported errors (about 50% error rate): URI --- /deliverEval/download.jsp Code Message: Error sending file '/home/sd/ShippingMasters/DMS/Domains/C/GCC3/Tools/TestCoverage/SD_C~GCC3_TestCoverage.1.6.12.exe' to client Stack Trace ----------- null at org.apache.coyote.tomcat5.OutputBuffer.realWriteBytes(byte[], int, int) (Unknown Source) at org.apache.tomcat.util.buf.ByteChunk.append(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.OutputBuffer.writeBytes(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.OutputBuffer.write(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.CoyoteOutputStream.write(byte[], int, int) (Unknown Source) at org.apache.jsp.deliverEval.download_jsp._jspService(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at org.apache.jasper.runtime.HttpJspBase.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at javax.servlet.http.HttpServlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.jasper.servlet.JspServletWrapper.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, boolean) (Unknown Source) at org.apache.jasper.servlet.JspServlet.serviceJspFile(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, java.lang.String, java.lang.Throwable, boolean) (Unknown Source) at org.apache.jasper.servlet.JspServlet.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at javax.servlet.http.HttpServlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.StandardWrapperValve.invoke(org.apache.catalina.Request, org.apache.catalina.Response, org.apache.catalina.ValveContext) (Unknown Source) We don't understand why this rate should be so high. Is there any way to get more information about the cause of the error? It is useful to know that these are pretty big documents, 3-50 megabytes. They reside on the Linux server so reading them is just a local disk read, and is unlikely to be a contributor to the problem. But sheer size might be an issue for the recipients browser? Is this kind of error rate typical for downloads? My personal experience downloading other's documents suggests no; our internal attempts show this to be very reliable, but we're operating on our internal network for such experiments so we're missing the complexity of the intervening internet.

• BAM design pointers

  - by Kavitha Srinivasan

  In working recently with a large Oracle customer on SOA and BAM, I discovered that some BAM best practices are not quite well known as I had always assumed ! There is a doc bug out to formally incorporate those learnings but here are a few notes..  EMS-DO parity When using EMS (Enterprise Message Source) as a BAM feed, the best practice is to use one EMS to write to one Data Object. There is a possibility of collisions and duplicates when multiple EMS write to the same row of a DO at the same time. This customer had 17 EMS writing to one DO at the same time. Every sensor in their BPEL process writes to one topic but the Topic was read by 1 EMS corresponding to one sensor. They then used XSL within BAM to transform the payload into the BAM DO format. And hence for a given BPEL instance, 17 sensors fired, populated 1 JMS topic, was consumed by 17 EMS which in turn wrote to 1 DataObject.(You can image what would happen for later versions of the application that needs to send more information to BAM !).  We modified their design to use one Master XSL based on sensorname for all sensors relating to a DO- say Data Object 'Orders' and were able to thus reduce the 17 EMS to 1 with a master XSL. For those of you wondering about how squeaky clean this design is, you are right ! This is indeed not squeaky clean and that brings us to yet another 'inferred' best practice. (I try very hard not to state the obvious in my blogs with the hope that everytime I blog, it is very useful but this one is an exception.) Transformations and Calculations It is optimal to do transformations within an engine like BPEL. Not only does this provide modelling ease with a nice GUI XSL mapper in JDeveloper, the XSL engine in BPEL is quite efficient at runtime as well. And so, doing XSL transformations in BAM is not quite prudent.  The same is true for any non-trivial calculations as well. It is best to do all transformations,calcuations and sanitize the data in a BPEL or like layer and then send this to BAM (via JMS, WS etc.) This then delegates simply the function of report rendering and mechanics of real-time reporting to the Oracle BAM reporting tool which it is most suited to do. All nulls are not created equal Here is yet another possibly known fact but reiterated here. For an EMS with an Upsert operation: a) If Empty tags or tags with no value are sent like <Tag1/> or <Tag1></Tag1>, the DO will be overwritten with --null-- b) If Empty tags are suppressed ie not generated at all, the corresponding DO field will NOT be overwritten. The field will have whatever value existed previously.  For an EMS with an Insert operation, both tags with an empty value and no tags result in –null-- being written to the DO. Hope this helps .. Happy 4th!

• PeopleSoft HCM @ OHUG 11: Enter the Matrix

  - by Jay Zuckert

  The PeopleSoft HCM team is back from a very busy and exciting OHUG conference in Orlando. The packed, standing-room only PeopleSoft HCM Roadmap keynote was the highlight of the conference for many attendees and the reviews are in : PeopleSoft rocked the house ! Great demonstration of products in the keynote. Best keynote in a long time, and fun. Engaging and entertaining, great demonstration of capabilities. Message received loud and clear, PeopleSoft applications are here to stay.  PeopleSoft has a real vision moving forward. Real-time polls using mobile texting were cutting edge.                          Tracy Martin (as Trinity) and other members of the PeopleSoft HCM team presented a ‘must-see’ Matrix-themed session while dressed as movie characters. The keynote highlighted planned HCM capabilities for Matrix administration and future organization visualization enhancements. The team also previewed the planned Manager Dashboard and Talent Summary.                           Following the keynote, some of the cast posed for photo opportunities at the OHUG booth in the exhibition hall. As you can imagine, they received some interesting looks walking by the other vendor booths. The PeopleSoft HCM team also presented numerous other OHUG sessions covering PeopleSoft Talent Management, Compensation, HR HelpDesk, Payroll, Global HCM Practices, Time & Labor, Absence Management, and Benefits. All of those presentations are available from the OHUG site at www.ohug.org. When not in one of the well-attended PeopleSoft HCM sessions, conference attendees filled the Oracle booth in the exhibition hall to see live product demonstrations. True to their PeopleSoft roots, some of the PeopleSoft HCM team played as hard as they worked in Orlando and enjoyed the OHUG Appreciation event along with customers at the Hard Rock. We are already busy planning for Oracle OpenWorld 2011 and prepping sessions our PeopleSoft HCM customers are sure to like. We hope to see you there in San Francisco from Oct. 2-6.

• Reset All Internet Explorer 8 Settings to Fix Stability Problems

  - by Mysticgeek

  If you like to tweak and customize IE with Add-ons and changing settings, sometimes you may have problems with stability. To save time, you can reset all of the IE settings rather than trying to troubleshoot individual areas. Reset IE Settings To reset Internet Explorer Settings, click on Tools then Internet Options. When you reset the settings, you won’t lose personal settings like your homepage, search provider, passwords…etc. The Internet Options screen opens…click on the Advanced tab, then under Reset Internet Explorer settings click on the Reset button. You’ll need to verify that you want to reset all Internet Explorer Settings. If you choose to, you can delete all of your personal settings as well, but it shouldn’t be necessary to fix stability issues. The settings will start to reset, and when it’s finished close out of the message box. For the process to complete you’ll need to restart Internet Explorer. When it restarts you’ll be presented with the Welcome screen where you can go through the setup wizard again. After it’s complete, you should be back in business and can start using IE again. With the new enhancements and features available in Internet Explorer 8, sometimes too much tweaking can cause it to stop working. One area you could start with is troubleshooting IE 8 Add-ons. However, if you don’t want to waste time troubleshooting each potential issue, sometimes it’s just easier to reset things back to how they were originally.

• Why does my MySQL remote-connection fail (VLAN)?

  - by Johannes Nielsen

  ubuntu-community! Again I have a problem with my special friend MySQL :D I have got two servers - a database-server and a web-server - who are connected via VLAN. Now I want the web-server to have remote access to the database-server's MySQL. So I created the user user in mysql.user. user's Host is xxx.yyy.zzz.9 which is the internal IP-address of the web-server. xxx.yyy.zzz.0 is the network. I also created user with Host % . As long as I use MySQL on the database-server logging in as user, everything works fine. But trying to log in as user from xxx.yyy.zzz.9 using mysql -h xxx.yyy.zzz.8 -u user -p (where xxx.yyy.zzz.8 is the database-server's internal IP), I get ERROR 2003 (HY000): Can't connect to MySQL server on 'xxx.yyy.zzz.8' (110) So I tried to activate Bind-Address in the my.cnf file. Well, if I use xxx.yyy.zzz.8, nothing changes. But if I try xxx.yyy.zzz.9 and try to restart MySQL, I get mysql stop/waiting start: Job failed to start I checked the log files and found - nothing. The database-server's MySQL doesn't even register, that the web-server tries to connect remotely. My idea is, that maybe I didn't configure the VLAN properley, even though I asked someone who actually knows such stuff and he told me, I did everything right. What I wrote into /etc/networking/interfaces is: #The VLAN auto eth1 iface eth1 inet static address xxx.yyy.zzz..8 netmask 255.255.255.0 network xxx.yyy.zzz.0 broadcast xxx.yyy.zzz.255 mtu 1500 ifconfig returns eth1 Link encap:Ethernet HWaddr xxxxxxxxxxxxxx inet addr:xxx.yyy.zzz.8 Bcast:xxx.yyy.zzz.255 Mask:255.255.255.0 inet6 addr: xxxxxxxxxxxxxxx/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:241146 errors:0 dropped:0 overruns:0 frame:0 TX packets:9765 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:17825995 (17.8 MB) TX bytes:566602 (566.6 KB) Memory:fb900000-fb920000 for the eth1, what is, what I configured. (This is for the database-server, the web-server looks similar). ethtool eth1 returns: Settings for eth1: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Supports Wake-on: d Wake-on: d Current message level: 0x00000003 (3) drv probe Link detected: yes (This is for the database-server, the web-server looks similar). Actually I think, everything is right, but it still doesn't work. Is there someone with an idea? EDIT: I commented ou Bind-Address in my.cnf after it didn't work.

• Generate DROP statements for all extended properties

  - by jamiet

  This evening I have been attempting to migrate an existing on-premise database to SQL Azure using the wizard that is built-in to SQL Server Management Studio (SSMS). When I did so I received the following error: The following objects are not supported = [MS_Description] = Extended Property Evidently databases containing extended properties can not be migrated using this particular wizard so I set about removing all of the extended properties – unfortunately there were over a thousand of them so I needed a better way than simply deleting each and every one of them manually. I found a couple of resources online that went some way toward this: Drop all extended properties in a MSSQL database by Angelo Hongens Modifying and deleting extended properties by Adam Aspin Unfortunately neither provided a script that exactly suited my needs. Angelo’s covered extended properties on tables and columns however I had other objects that had extended properties on them. Adam’s looked more complete but when I ran it I got an error: Msg 468, Level 16, State 9, Line 78 Cannot resolve the collation conflict between "Latin1_General_100_CS_AS" and "Latin1_General_CI_AS" in the equal to operation. So, both great resources but I wasn’t able to use either on their own to get rid of all of my extended properties. Hence, I combined the excellent work that Angelo and Adam had provided in order to manufacture my own script which did successfully manage to generate calls to sp_dropextendedproperty for all of my extended properties. If you think you might be able to make use of such a script then feel free to download it from https://skydrive.live.com/redir.aspx?cid=550f681dad532637&resid=550F681DAD532637!16707&parid=550F681DAD532637!16706&authkey=!APxPIQCatzC7BQ8. This script will remove extended properties on tables, columns, check constraints, default constraints, views, sprocs, foreign keys, primary keys, table triggers, UDF parameters, sproc parameters, databases, schemas, database files and filegroups. If you have any object types with extended properties on them that are not in that list then consult Adam’s aforementioned article – it should prove very useful. I repeat here the message that I have placed at the top of the script: /* This script will generate calls to sp_dropextendedproperty for every extended property that exists in your database. Actually, a caveat: I don't promise that it will catch each and every extended property that exists, but I'm confident it will catch most of them! It is based on this: http://blog.hongens.nl/2010/02/25/drop-all-extended-properties-in-a-mssql-database/ by Angelo Hongens. Also had lots of help from this: http://www.sqlservercentral.com/articles/Metadata/72609/ by Adam Aspin Adam actually provides a script at that link to do something very similar but when I ran it I got an error: Msg 468, Level 16, State 9, Line 78 Cannot resolve the collation conflict between "Latin1_General_100_CS_AS" and "Latin1_General_CI_AS" in the equal to operation. So I put together this version instead. Use at your own risk. Jamie Thomson 2012-03-25 */ Hope this is useful to someone! @Jamiet

• Excel tables creation upon MySQL data import (new feature in MySQL for Excel 1.2.x)

  - by Javier Treviño

  In this blog post we are going to talk about one of the features included since MySQL for Excel 1.2.0, you can install the latest GA or maintenance version using the MySQL Installer or optionally you can download directly any GA or non-GA version from the MySQL Developer Zone. Remember how easy is to dump data from a MySQL table, view or stored procedure to an Excel worksheet? (If you don't you can check out this other post: How To - Guide to Importing Data from a MySQL Database to Excel using MySQL for Excel). In version 1.2.0 we introduced some advanced options for the Import MySQL Data operation regarding Excel tables. The Advanced Options dialog shown above is accessible from any Import Data dialog. When the Create an Excel table for the imported MySQL table data option is checked (which is by default), MySQL for Excel will create an Excel table (also known in Excel jargon as a ListObject) from the Excel range containing the imported MySQL data. This "little feature" enables the right-away usage of the Excel table in data analysis, like including it for summarization on a PivotTable, including a summarization row at the end of the table's data, sorting or filtering the table's data by clicking the drop-down button next to each column's header, among other actions. The Excel tables that are created automatically from imported MySQL data will have a name like [UserPrefix].<SchemaName>.<DbObjectName> for tables and views, and <Prefix>.<SchemaName>.<ProcedureName>.<ResultSetName> for stored procedures.  Notice the first piece of the name is an optional [UserPrefix], the prefix is only used if the Prefix Excel tables with the following text option is checked, notice that the suggested prefix is "MySQL" but it can be changed to whatever text is suitable for you. Excel tables must have a table style so they are easily identified. There are a lot of predefined Excel table styles, by default the MySqlDefault style is applied, which is the style you have seen applied to imported data for Edit Sessions, and which adds simple and elegant formatting to the table. If you wish to change it to any of the predefined Excel table style you can do it through the drop-down list on the Use style [[styles drop-down]] for the new Excel table option. Excel tables are the basic construction blocks for building data analysis or self-service Business Intelligence using other more advanced Excel tools like Power Pivot, Power View or Power Map. This feature empowers imported MySQL data to use it in more advanced ways.  We hope you give this and the other new features in the 1.2.x version family a try! Remember that your feedback is very important for us, so drop us a message and follow us: MySQL on Windows (this) Blog: https://blogs.oracle.com/MySqlOnWindows/ MySQL for Excel forum: http://forums.mysql.com/list.php?172 Facebook: http://www.facebook.com/mysql YouTube channel: https://www.youtube.com/user/MySQLChannel Cheers!

• How to repair an external harddrive?

  - by dodohjk

  I would like to reformat my hard disk, and if possible recover the (somewhat unimportant) contents if possible. I have a Western Digital 1TB hard drive which had a NTFS partition. I unplugged the drive without safely removing it first. At first a pop up was asking me to use a Windows OS to run the chkdsk /f command, however, in the effort to keep using a Linux OS I used the ntfsfix command on the ubuntu terminal Now, when I try to access the hard drive, it doesn't show up anymore in Nautilus. I tried reformatting it using Disk Utility, but it gives me an error message, and Gparted would hang on the "Scanning devices" step infinitely. Please comment any output that you would like to see and I will add it to my question.

• Inside the Concurrent Collections: ConcurrentDictionary

  - by Simon Cooper

  Using locks to implement a thread-safe collection is rather like using a sledgehammer - unsubtle, easy to understand, and tends to make any other tool redundant. Unlike the previous two collections I looked at, ConcurrentStack and ConcurrentQueue, ConcurrentDictionary uses locks quite heavily. However, it is careful to wield locks only where necessary to ensure that concurrency is maximised. This will, by necessity, be a higher-level look than my other posts in this series, as there is quite a lot of code and logic in ConcurrentDictionary. Therefore, I do recommend that you have ConcurrentDictionary open in a decompiler to have a look at all the details that I skip over. The problem with locks There's several things to bear in mind when using locks, as encapsulated by the lock keyword in C# and the System.Threading.Monitor class in .NET (if you're unsure as to what lock does in C#, I briefly covered it in my first post in the series): Locks block threads The most obvious problem is that threads waiting on a lock can't do any work at all. No preparatory work, no 'optimistic' work like in ConcurrentQueue and ConcurrentStack, nothing. It sits there, waiting to be unblocked. This is bad if you're trying to maximise concurrency. Locks are slow Whereas most of the methods on the Interlocked class can be compiled down to a single CPU instruction, ensuring atomicity at the hardware level, taking out a lock requires some heavy lifting by the CLR and the operating system. There's quite a bit of work required to take out a lock, block other threads, and wake them up again. If locks are used heavily, this impacts performance. Deadlocks When using locks there's always the possibility of a deadlock - two threads, each holding a lock, each trying to aquire the other's lock. Fortunately, this can be avoided with careful programming and structured lock-taking, as we'll see. So, it's important to minimise where locks are used to maximise the concurrency and performance of the collection. Implementation As you might expect, ConcurrentDictionary is similar in basic implementation to the non-concurrent Dictionary, which I studied in a previous post. I'll be using some concepts introduced there, so I recommend you have a quick read of it. So, if you were implementing a thread-safe dictionary, what would you do? The naive implementation is to simply have a single lock around all methods accessing the dictionary. This would work, but doesn't allow much concurrency. Fortunately, the bucketing used by Dictionary allows a simple but effective improvement to this - one lock per bucket. This allows different threads modifying different buckets to do so in parallel. Any thread making changes to the contents of a bucket takes the lock for that bucket, ensuring those changes are thread-safe. The method that maps each bucket to a lock is the GetBucketAndLockNo method: private void GetBucketAndLockNo( int hashcode, out int bucketNo, out int lockNo, int bucketCount) { // the bucket number is the hashcode (without the initial sign bit) // modulo the number of buckets bucketNo = (hashcode & 0x7fffffff) % bucketCount; // and the lock number is the bucket number modulo the number of locks lockNo = bucketNo % m_locks.Length; } However, this does require some changes to how the buckets are implemented. The 'implicit' linked list within a single backing array used by the non-concurrent Dictionary adds a dependency between separate buckets, as every bucket uses the same backing array. Instead, ConcurrentDictionary uses a strict linked list on each bucket: This ensures that each bucket is entirely separate from all other buckets; adding or removing an item from a bucket is independent to any changes to other buckets. Modifying the dictionary All the operations on the dictionary follow the same basic pattern: void AlterBucket(TKey key, ...) { int bucketNo, lockNo; 1: GetBucketAndLockNo( key.GetHashCode(), out bucketNo, out lockNo, m_buckets.Length); 2: lock (m_locks[lockNo]) { 3: Node headNode = m_buckets[bucketNo]; 4: Mutate the node linked list as appropriate } } For example, when adding another entry to the dictionary, you would iterate through the linked list to check whether the key exists already, and add the new entry as the head node. When removing items, you would find the entry to remove (if it exists), and remove the node from the linked list. Adding, updating, and removing items all follow this pattern. Performance issues There is a problem we have to address at this point. If the number of buckets in the dictionary is fixed in the constructor, then the performance will degrade from O(1) to O(n) when a large number of items are added to the dictionary. As more and more items get added to the linked lists in each bucket, the lookup operations will spend most of their time traversing a linear linked list. To fix this, the buckets array has to be resized once the number of items in each bucket has gone over a certain limit. (In ConcurrentDictionary this limit is when the size of the largest bucket is greater than the number of buckets for each lock. This check is done at the end of the TryAddInternal method.) Resizing the bucket array and re-hashing everything affects every bucket in the collection. Therefore, this operation needs to take out every lock in the collection. Taking out mutiple locks at once inevitably summons the spectre of the deadlock; two threads each hold a lock, and each trying to acquire the other lock. How can we eliminate this? Simple - ensure that threads never try to 'swap' locks in this fashion. When taking out multiple locks, always take them out in the same order, and always take out all the locks you need before starting to release them. In ConcurrentDictionary, this is controlled by the AcquireLocks, AcquireAllLocks and ReleaseLocks methods. Locks are always taken out and released in the order they are in the m_locks array, and locks are all released right at the end of the method in a finally block. At this point, it's worth pointing out that the locks array is never re-assigned, even when the buckets array is increased in size. The number of locks is fixed in the constructor by the concurrencyLevel parameter. This simplifies programming the locks; you don't have to check if the locks array has changed or been re-assigned before taking out a lock object. And you can be sure that when a thread takes out a lock, another thread isn't going to re-assign the lock array. This would create a new series of lock objects, thus allowing another thread to ignore the existing locks (and any threads controlling them), breaking thread-safety. Consequences of growing the array Just because we're using locks doesn't mean that race conditions aren't a problem. We can see this by looking at the GrowTable method. The operation of this method can be boiled down to: private void GrowTable(Node[] buckets) { try { 1: Acquire first lock in the locks array // this causes any other thread trying to take out // all the locks to block because the first lock in the array // is always the one taken out first // check if another thread has already resized the buckets array // while we were waiting to acquire the first lock 2: if (buckets != m_buckets) return; 3: Calculate the new size of the backing array 4: Node[] array = new array[size]; 5: Acquire all the remaining locks 6: Re-hash the contents of the existing buckets into array 7: m_buckets = array; } finally { 8: Release all locks } } As you can see, there's already a check for a race condition at step 2, for the case when the GrowTable method is called twice in quick succession on two separate threads. One will successfully resize the buckets array (blocking the second in the meantime), when the second thread is unblocked it'll see that the array has already been resized & exit without doing anything. There is another case we need to consider; looking back at the AlterBucket method above, consider the following situation: Thread 1 calls AlterBucket; step 1 is executed to get the bucket and lock numbers. Thread 2 calls GrowTable and executes steps 1-5; thread 1 is blocked when it tries to take out the lock in step 2. Thread 2 re-hashes everything, re-assigns the buckets array, and releases all the locks (steps 6-8). Thread 1 is unblocked and continues executing, but the calculated bucket and lock numbers are no longer valid. Between calculating the correct bucket and lock number and taking out the lock, another thread has changed where everything is. Not exactly thread-safe. Well, a similar problem was solved in ConcurrentStack and ConcurrentQueue by storing a local copy of the state, doing the necessary calculations, then checking if that state is still valid. We can use a similar idea here: void AlterBucket(TKey key, ...) { while (true) { Node[] buckets = m_buckets; int bucketNo, lockNo; GetBucketAndLockNo( key.GetHashCode(), out bucketNo, out lockNo, buckets.Length); lock (m_locks[lockNo]) { // if the state has changed, go back to the start if (buckets != m_buckets) continue; Node headNode = m_buckets[bucketNo]; Mutate the node linked list as appropriate } break; } } TryGetValue and GetEnumerator And so, finally, we get onto TryGetValue and GetEnumerator. I've left these to the end because, well, they don't actually use any locks. How can this be? Whenever you change a bucket, you need to take out the corresponding lock, yes? Indeed you do. However, it is important to note that TryGetValue and GetEnumerator don't actually change anything. Just as immutable objects are, by definition, thread-safe, read-only operations don't need to take out a lock because they don't change anything. All lockless methods can happily iterate through the buckets and linked lists without worrying about locking anything. However, this does put restrictions on how the other methods operate. Because there could be another thread in the middle of reading the dictionary at any time (even if a lock is taken out), the dictionary has to be in a valid state at all times. Every change to state has to be made visible to other threads in a single atomic operation (all relevant variables are marked volatile to help with this). This restriction ensures that whatever the reading threads are doing, they never read the dictionary in an invalid state (eg items that should be in the collection temporarily removed from the linked list, or reading a node that has had it's key & value removed before the node itself has been removed from the linked list). Fortunately, all the operations needed to change the dictionary can be done in that way. Bucket resizes are made visible when the new array is assigned back to the m_buckets variable. Any additions or modifications to a node are done by creating a new node, then splicing it into the existing list using a single variable assignment. Node removals are simply done by re-assigning the node's m_next pointer. Because the dictionary can be changed by another thread during execution of the lockless methods, the GetEnumerator method is liable to return dirty reads - changes made to the dictionary after GetEnumerator was called, but before the enumeration got to that point in the dictionary. It's worth listing at this point which methods are lockless, and which take out all the locks in the dictionary to ensure they get a consistent view of the dictionary: Lockless: TryGetValue GetEnumerator The indexer getter ContainsKey Takes out every lock (lockfull?): Count IsEmpty Keys Values CopyTo ToArray Concurrent principles That covers the overall implementation of ConcurrentDictionary. I haven't even begun to scratch the surface of this sophisticated collection. That I leave to you. However, we've looked at enough to be able to extract some useful principles for concurrent programming: Partitioning When using locks, the work is partitioned into independant chunks, each with its own lock. Each partition can then be modified concurrently to other partitions. Ordered lock-taking When a method does need to control the entire collection, locks are taken and released in a fixed order to prevent deadlocks. Lockless reads Read operations that don't care about dirty reads don't take out any lock; the rest of the collection is implemented so that any reading thread always has a consistent view of the collection. That leads us to the final collection in this little series - ConcurrentBag. Lacking a non-concurrent analogy, it is quite different to any other collection in the class libraries. Prepare your thinking hats!

• When to use HTTP status code 404 in an API

  - by Sybiam

  I am working on a project and after arguing with people at work for about more than a hour. I decided to know what people on stack-exchange might say. We're writing an API for a system, there is a query that should return a tree of Organization or a tree of Goals. The tree of Organization is the organization in which the user is present, In other words, this tree should always exists. In the organization, a tree of goal should be always present. (that's where the argument started). In case where the tree doesn't exist, my co-worker decided that it would be right to answer response with status code 200. And then started asking me to fix my code because the application was falling apart when there is no tree. I'll try to spare flames and fury. I suggested to raise a 404 error when there is no tree. It would at least let me know that something is wrong. When using 200, I have to add special check to my response in the success callback to handle errors. I'm expecting to receive an object, but I may actually receive an empty response because nothing is found. It sounds totally fair to mark the response as a 404. And then war started and I got the message that I didn't understand HTTP status code schema. So I'm here and asking what's wrong with 404 in this case? I even got the argument "It found nothing, so it's right to return 200". I believe that it's wrong since the tree should be always present. If we found nothing and we are expecting something, it should be a 404. More info, I forgot to add the urls that are fetched. Organizations /OrgTree/Get Goals /GoalTree/GetByDate?versionDate=... /GoalTree/GetById?versionId=... My mistake, both parameters are required. If any versionDate that can be parsed to a date is provided, it will return the closes revision. If you enter something in the past, it will return the first revision. If by Id with a id that doesn't exists, I suspect it's going to return an empty response with 200. Extra Also, I believe the best answer to the problem is to create default objects when organizations are created, having no tree shouldn't be a valid case and should be seen as an undefined behavior. There is no way an account can be used without both trees. For that reasons, they should be always present. also I got linked this (one similar but I can't find it) http://viswaug.files.wordpress.com/2008/11/http-headers-status1.png

• Ghost team foundation build controllers

  - by Martin Hinshelwood

  Quite often after an upgrade there are things left over. Most of the time they are easy to delete, but sometimes it takes a little effort. Even rarer are those times when something just will not go away no matter how much you try. We have had a ghost team build controller hanging around for a while now, and it had defeated my best efforts to get rid of it. The build controller was from our old TFS server from before our TFS 2010 beta 2 upgrade and was really starting to annoy me. Every time I try to delete it I get the message: Controller cannot be deleted because there are build in progress -Manage Build Controller dialog   Figure: Deleting a ghost controller does not always work. I ended up checking all of our 172 Team Projects for the build that was queued, but did not find anything. Jim Lamb pointed me to the “tbl_BuildQueue” table in the team Project Collection database and sure enough there was the nasty little beggar. Figure: The ghost build was easily spotted Adam Cogan asked me: “Why did you suspect this one?” Well, there are a number of things that led me to suspect it: QueueId is very low: Look at the other items, they are in the thousands not single digits ControllerId: I know there is only one legitimate controller, and I am assuming that 6 relates to “zzUnicorn” DefinitionId: This is a very low number and I looked it up in “tbl_BuildDefinition” and it did not exist QueueTime: As we did not upgrade to TFS 2010 until late 2009 a date of 2008 for a queued build is very suspect Status: A status of 2 means that it is still queued This build must have been queued long ago when we were using TFS 2008, probably a beta, and it never got cleaned up. As controllers are new in TFS 2010 it would have created the “zzUnicorn” controller to handle any build servers that already exist. I had previously deleted the Agent, but leaving the controller just looks untidy. Now that the ghost build has been identified there are two options: Delete the row I would not recommend ever deleting anything from the database to achieve something in TFS. It is really not supported. Set the Status to cancelled (Recommended) This is the best option as TFS will then clean it up itself So I set the Status of this build to 2 (cancelled) and sure enough it disappeared after a couple of minutes and I was then able to then delete the “zzUnicorn” controller. Figure: Almost completely clean Now all I have to do is get rid of that untidy “zzBunyip” agent, but that will require rewriting one of our build scripts which will have to wait for now.   Technorati Tags: ALM,TFBS,TFS 2010

• Dynamically loading Assemblies to reduce Runtime Depencies

  - by Rick Strahl

  I've been working on a request to the West Wind Application Configuration library to add JSON support. The config library is a very easy to use code-first approach to configuration: You create a class that holds the configuration data that inherits from a base configuration class, and then assign a persistence provider at runtime that determines where and how the configuration data is store. Currently the library supports .NET Configuration stores (web.config/app.config), XML files, SQL records and string storage.About once a week somebody asks me about JSON support and I've deflected this question for the longest time because frankly I think that JSON as a configuration store doesn't really buy a heck of a lot over XML. Both formats require the user to perform some fixup of the plain configuration data - in XML into XML tags, with JSON using JSON delimiters for properties and property formatting rules. Sure JSON is a little less verbose and maybe a little easier to read if you have hierarchical data, but overall the differences are pretty minor in my opinion. And yet - the requests keep rolling in.Hard Link Issues in a Component LibraryAnother reason I've been hesitant is that I really didn't want to pull in a dependency on an external JSON library - in this case JSON.NET - into the core library. If you're not using JSON.NET elsewhere I don't want a user to have to require a hard dependency on JSON.NET unless they want to use the JSON feature. JSON.NET is also sensitive to versions and doesn't play nice with multiple versions when hard linked. For example, when you have a reference to V4.4 in your project but the host application has a reference to version 4.5 you can run into assembly load problems. NuGet's Update-Package can solve some of this *if* you can recompile, but that's not ideal for a component that's supposed to be just plug and play. This is no criticism of JSON.NET - this really applies to any dependency that might change.  So hard linking the DLL can be problematic for a number reasons, but the primary reason is to not force loading of JSON.NET unless you actually need it when you use the JSON configuration features of the library.Enter Dynamic LoadingSo rather than adding an assembly reference to the project, I decided that it would be better to dynamically load the DLL at runtime and then use dynamic typing to access various classes. This allows me to run without a hard assembly reference and allows more flexibility with version number differences now and in the future.But there are also a couple of downsides:No assembly reference means only dynamic access - no compiler type checking or IntellisenseRequirement for the host application to have reference to JSON.NET or else get runtime errorsThe former is minor, but the latter can be problematic. Runtime errors are always painful, but in this case I'm willing to live with this. If you want to use JSON configuration settings JSON.NET needs to be loaded in the project. If this is a Web project, it'll likely be there already.So there are a few things that are needed to make this work:Dynamically create an instance and optionally attempt to load an Assembly (if not loaded)Load types into dynamic variablesUse Reflection for a few tasks like statics/enumsThe dynamic keyword in C# makes the formerly most difficult Reflection part - method calls and property assignments - fairly painless. But as cool as dynamic is it doesn't handle all aspects of Reflection. Specifically it doesn't deal with object activation, truly dynamic (string based) member activation or accessing of non instance members, so there's still a little bit of work left to do with Reflection.Dynamic Object InstantiationThe first step in getting the process rolling is to instantiate the type you need to work with. This might be a two step process - loading the instance from a string value, since we don't have a hard type reference and potentially having to load the assembly. Although the host project might have a reference to JSON.NET, that instance might have not been loaded yet since it hasn't been accessed yet. In ASP.NET this won't be a problem, since ASP.NET preloads all referenced assemblies on AppDomain startup, but in other executable project, assemblies are just in time loaded only when they are accessed.Instantiating a type is a two step process: Finding the type reference and then activating it. Here's the generic code out of my ReflectionUtils library I use for this:/// <summary> /// Creates an instance of a type based on a string. Assumes that the type's /// </summary> /// <param name="typeName">Common name of the type</param> /// <param name="args">Any constructor parameters</param> /// <returns></returns> public static object CreateInstanceFromString(string typeName, params object[] args) { object instance = null; Type type = null; try { type = GetTypeFromName(typeName); if (type == null) return null; instance = Activator.CreateInstance(type, args); } catch { return null; } return instance; } /// <summary> /// Helper routine that looks up a type name and tries to retrieve the /// full type reference in the actively executing assemblies. /// </summary> /// <param name="typeName"></param> /// <returns></returns> public static Type GetTypeFromName(string typeName) { Type type = null; // Let default name binding find it type = Type.GetType(typeName, false); if (type != null) return type; // look through assembly list var assemblies = AppDomain.CurrentDomain.GetAssemblies(); // try to find manually foreach (Assembly asm in assemblies) { type = asm.GetType(typeName, false); if (type != null) break; } return type; } To use this for loading JSON.NET I have a small factory function that instantiates JSON.NET and sets a bunch of configuration settings on the generated object. The startup code also looks for failure and tries loading up the assembly when it fails since that's the main reason the load would fail. Finally it also caches the loaded instance for reuse (according to James the JSON.NET instance is thread safe and quite a bit faster when cached). Here's what the factory function looks like in JsonSerializationUtils:/// <summary> /// Dynamically creates an instance of JSON.NET /// </summary> /// <param name="throwExceptions">If true throws exceptions otherwise returns null</param> /// <returns>Dynamic JsonSerializer instance</returns> public static dynamic CreateJsonNet(bool throwExceptions = true) { if (JsonNet != null) return JsonNet; lock (SyncLock) { if (JsonNet != null) return JsonNet; // Try to create instance dynamic json = ReflectionUtils.CreateInstanceFromString("Newtonsoft.Json.JsonSerializer"); if (json == null) { try { var ass = AppDomain.CurrentDomain.Load("Newtonsoft.Json"); json = ReflectionUtils.CreateInstanceFromString("Newtonsoft.Json.JsonSerializer"); } catch (Exception ex) { if (throwExceptions) throw; return null; } } if (json == null) return null; json.ReferenceLoopHandling = (dynamic) ReflectionUtils.GetStaticProperty("Newtonsoft.Json.ReferenceLoopHandling", "Ignore"); // Enums as strings in JSON dynamic enumConverter = ReflectionUtils.CreateInstanceFromString("Newtonsoft.Json.Converters.StringEnumConverter"); json.Converters.Add(enumConverter); JsonNet = json; } return JsonNet; }This code's purpose is to return a fully configured JsonSerializer instance. As you can see the code tries to create an instance and when it fails tries to load the assembly, and then re-tries loading.Once the instance is loaded some configuration occurs on it. Specifically I set the ReferenceLoopHandling option to not blow up immediately when circular references are encountered. There are a host of other small config setting that might be useful to set, but the default seem to be good enough in recent versions. Note that I'm setting ReferenceLoopHandling which requires an Enum value to be set. There's no real easy way (short of using the cardinal numeric value) to set a property or pass parameters from static values or enums. This means I still need to use Reflection to make this work. I'm using the same ReflectionUtils class I previously used to handle this for me. The function looks up the type and then uses Type.InvokeMember() to read the static property.Another feature I need is have Enum values serialized as strings rather than numeric values which is the default. To do this I can use the StringEnumConverter to convert enums to strings by adding it to the Converters collection.As you can see there's still a bit of Reflection to be done even in C# 4+ with dynamic, but with a few helpers this process is relatively painless.Doing the actual JSON ConversionFinally I need to actually do my JSON conversions. For the Utility class I need serialization that works for both strings and files so I created four methods that handle these tasks two each for serialization and deserialization for string and file.Here's what the File Serialization looks like:/// <summary> /// Serializes an object instance to a JSON file. /// </summary> /// <param name="value">the value to serialize</param> /// <param name="fileName">Full path to the file to write out with JSON.</param> /// <param name="throwExceptions">Determines whether exceptions are thrown or false is returned</param> /// <param name="formatJsonOutput">if true pretty-formats the JSON with line breaks</param> /// <returns>true or false</returns> public static bool SerializeToFile(object value, string fileName, bool throwExceptions = false, bool formatJsonOutput = false) { dynamic writer = null; FileStream fs = null; try { Type type = value.GetType(); var json = CreateJsonNet(throwExceptions); if (json == null) return false; fs = new FileStream(fileName, FileMode.Create); var sw = new StreamWriter(fs, Encoding.UTF8); writer = Activator.CreateInstance(JsonTextWriterType, sw); if (formatJsonOutput) writer.Formatting = (dynamic)Enum.Parse(FormattingType, "Indented"); writer.QuoteChar = '"'; json.Serialize(writer, value); } catch (Exception ex) { Debug.WriteLine("JsonSerializer Serialize error: " + ex.Message); if (throwExceptions) throw; return false; } finally { if (writer != null) writer.Close(); if (fs != null) fs.Close(); } return true; }You can see more of the dynamic invocation in this code. First I grab the dynamic JsonSerializer instance using the CreateJsonNet() method shown earlier which returns a dynamic. I then create a JsonTextWriter and configure a couple of enum settings on it, and then call Serialize() on the serializer instance with the JsonTextWriter that writes the output to disk. Although this code is dynamic it's still fairly short and readable.For full circle operation here's the DeserializeFromFile() version:/// <summary> /// Deserializes an object from file and returns a reference. /// </summary> /// <param name="fileName">name of the file to serialize to</param> /// <param name="objectType">The Type of the object. Use typeof(yourobject class)</param> /// <param name="binarySerialization">determines whether we use Xml or Binary serialization</param> /// <param name="throwExceptions">determines whether failure will throw rather than return null on failure</param> /// <returns>Instance of the deserialized object or null. Must be cast to your object type</returns> public static object DeserializeFromFile(string fileName, Type objectType, bool throwExceptions = false) { dynamic json = CreateJsonNet(throwExceptions); if (json == null) return null; object result = null; dynamic reader = null; FileStream fs = null; try { fs = new FileStream(fileName, FileMode.Open, FileAccess.Read); var sr = new StreamReader(fs, Encoding.UTF8); reader = Activator.CreateInstance(JsonTextReaderType, sr); result = json.Deserialize(reader, objectType); reader.Close(); } catch (Exception ex) { Debug.WriteLine("JsonNetSerialization Deserialization Error: " + ex.Message); if (throwExceptions) throw; return null; } finally { if (reader != null) reader.Close(); if (fs != null) fs.Close(); } return result; }This code is a little more compact since there are no prettifying options to set. Here JsonTextReader is created dynamically and it receives the output from the Deserialize() operation on the serializer.You can take a look at the full JsonSerializationUtils.cs file on GitHub to see the rest of the operations, but the string operations are very similar - the code is fairly repetitive.These generic serialization utilities isolate the dynamic serialization logic that has to deal with the dynamic nature of JSON.NET, and any code that uses these functions is none the wiser that JSON.NET is dynamically loaded.Using the JsonSerializationUtils WrapperThe final consumer of the SerializationUtils wrapper is an actual ConfigurationProvider, that is responsible for handling reading and writing JSON values to and from files. The provider is simple a small wrapper around the SerializationUtils component and there's very little code to make this work now:The whole provider looks like this:/// <summary> /// Reads and Writes configuration settings in .NET config files and /// sections. Allows reading and writing to default or external files /// and specification of the configuration section that settings are /// applied to. /// </summary> public class JsonFileConfigurationProvider<TAppConfiguration> : ConfigurationProviderBase<TAppConfiguration> where TAppConfiguration: AppConfiguration, new() { /// <summary> /// Optional - the Configuration file where configuration settings are /// stored in. If not specified uses the default Configuration Manager /// and its default store. /// </summary> public string JsonConfigurationFile { get { return _JsonConfigurationFile; } set { _JsonConfigurationFile = value; } } private string _JsonConfigurationFile = string.Empty; public override bool Read(AppConfiguration config) { var newConfig = JsonSerializationUtils.DeserializeFromFile(JsonConfigurationFile, typeof(TAppConfiguration)) as TAppConfiguration; if (newConfig == null) { if(Write(config)) return true; return false; } DecryptFields(newConfig); DataUtils.CopyObjectData(newConfig, config, "Provider,ErrorMessage"); return true; } /// <summary> /// Return /// </summary> /// <typeparam name="TAppConfig"></typeparam> /// <returns></returns> public override TAppConfig Read<TAppConfig>() { var result = JsonSerializationUtils.DeserializeFromFile(JsonConfigurationFile, typeof(TAppConfig)) as TAppConfig; if (result != null) DecryptFields(result); return result; } /// <summary> /// Write configuration to XmlConfigurationFile location /// </summary> /// <param name="config"></param> /// <returns></returns> public override bool Write(AppConfiguration config) { EncryptFields(config); bool result = JsonSerializationUtils.SerializeToFile(config, JsonConfigurationFile,false,true); // Have to decrypt again to make sure the properties are readable afterwards DecryptFields(config); return result; } }This incidentally demonstrates how easy it is to create a new provider for the West Wind Application Configuration component. Simply implementing 3 methods will do in most cases.Note this code doesn't have any dynamic dependencies - all that's abstracted away in the JsonSerializationUtils(). From here on, serializing JSON is just a matter of calling the static methods on the SerializationUtils class.Already, there are several other places in some other tools where I use JSON serialization this is coming in very handy. With a couple of lines of code I was able to add JSON.NET support to an older AJAX library that I use replacing quite a bit of code that was previously in use. And for any other manual JSON operations (in a couple of apps I use JSON Serialization for 'blob' like document storage) this is also going to be handy.Performance?Some of you might be thinking that using dynamic and Reflection can't be good for performance. And you'd be right… In performing some informal testing it looks like the performance of the native code is nearly twice as fast as the dynamic code. Most of the slowness is attributable to type lookups. To test I created a native class that uses an actual reference to JSON.NET and performance was consistently around 85-90% faster with the referenced code. That being said though - I serialized 10,000 objects in 80ms vs. 45ms so this isn't hardly slouchy. For the configuration component speed is not that important because both read and write operations typically happen once on first access and then every once in a while. But for other operations - say a serializer trying to handle AJAX requests on a Web Server one would be well served to create a hard dependency.Dynamic Loading - Worth it?On occasion dynamic loading makes sense. But there's a price to be paid in added code complexity and a performance hit. But for some operations that are not pivotal to a component or application and only used under certain circumstances dynamic loading can be beneficial to avoid having to ship extra files and loading down distributions. These days when you create new projects in Visual Studio with 30 assemblies before you even add your own code, trying to keep file counts under control seems a good idea. It's not the kind of thing you do on a regular basis, but when needed it can be a useful tool.
