• Is there a measure of code rot?

  - by DarenW

  I'm dealing, again, with a messy C++ application, tons of classes with confusing names, objects have pointers into each other and all over, longwinded Boost and STL data types, etc. (Pause and consider your favorite terror of messy legacy code. We probably have it.) The phrase "code rot" oft comes to mind when I work on this project. Is there a quantitative way to measure code rot? I wouldn't expect anything highly meaningful or scientific, since no other measure of code productivity or quality is so fine. I'm not looking for a mere opposite of measures of code quality, but specifically a measure of how many bad things happened after a series of maintenance software "engineers" have had turns hacking at the code. A general measure applying to any language, or many languages, would be great. If there's no such thing, at least for C++, which is a better than average language for creating messes. Maybe something involving a measure of topology of how objects connect during runtime, a count of chunks of commented out code, how mane files a typical variable's usage is scattered over, I don't know... but surely now, a decade into the 21st Century, someone has attempted to define some sort of rot measure. It would be especially interesting to automate a series of svn checkouts, measure the "rottenosity" of each, and plot the decay over time.

• Is it reasonable to expect knowing the whole stack bottom up?

  - by Vaibhav Garg

  I am an Sr. developer/architect/Product Manager for embedded systems. The systems that I have had experience with have typically been small to medium size codebases - typically close to 25-30K LOC in C, using 8-16 and 32 bit low end microcontrollers. The systems have been entirely bootstrapped by our team - meaning right from the start-up code to the end application code has either been written by the team, or at the very least, is thoroughly understood and maintained by us. Now, if we were to start developing more complex systems with complex peripherals, such as USB OTG et al. (think, low end cell phones), there are libraries and stacks available commercially and from chip vendors that reduce the task to just calling the right APIs and being able to use those peripherals. Now, from a habit point of view, this does not give me and the team a comfortable feeling, not being able to comprehend the entire code tree, with virtual black boxes at the lower layers. Is it reasonable to devote, and reserve, time getting into the details of how the APIs are implemented, assuming that the same would also entail getting into details of relevant standards (again, for USB as an example)? Or, alternatively, should a thorough understanding of the top level usage of the APIs be sufficient? This of course assumes that the source codes to all libraries are available, which they are, in almost all cases. Edit: In partial response to @Abhi Beckert, the documentation is refreshingly very comprehensive and meticulously maintained, AFAIK and been able to judge. I have not had a long experience with the same.

• Alternative to Game State System?

  - by Ricket

  As far as I can tell, most games have some sort of "game state system" which switches between the different game states; these might be things like "Intro", "MainMenu", "CharacterSelect", "Loading", and "Game". On the one hand, it totally makes sense to separate these into a state system. After all, they are disparate and would otherwise need to be in a large switch statement, which is obviously messy; and they certainly are well represented by a state system. But at the same time, I look at the "Game" state and wonder if there's something wrong about this state system approach. Because it's like the elephant in the room; it's HUGE and obvious but nobody questions the game state system approach. It seems silly to me that "Game" is put on the same level as "Main Menu". Yet there isn't a way to break up the "Game" state. Is a game state system the best way to go? Is there some different, better technique to managing, well, the "game state"? Is it okay to have an intro state which draws a movie and listens for enter, and then a loading state which loops on the resource manager, and then the game state which does practically everything? Doesn't this seem sort of unbalanced to you, too? Am I missing something?

• JDBC Connection Pools in Glassfish

  - by Dana Singleterry

  I've been attempting to configure Glassfish 3.1.2.2 for ADF 11g and the need arose to create a jdbc connection pool to my Oracle XE 11g database. While this is really very trivial there were no samples of how to do this and documentation, while good, rarely ever provides concrete examples. After fumbling around for a few minutes searching for an example I gave up and figured it out on my own. Here are the steps for any of you that may be in need. This can be done either via the Glassfish command line tool asadmin or through the admin console. I'm doing this through the admin console. Start Glassfish and connect to the admin console with the credentials you defined at installation: http://localhost:4848 Navigate to Resources | JDBC | JDBC Connection Pools and select New. Be sure to enter Resource Type & Datasource Classname under General Settings tab. You can go with the defaults for Pool Settings etc... View Image Go to the Additional Properties tab and create username, password, and url properties with the respective values. View Image Navigate to Resources | JDBC | JDBC Resources and select New. Be sure to enter the JNDI Name and select the Pool Name for the jdbc connection pool you created previously. View Image Navigate to Configurations | server-config | JVM Settings and select the JVM Options tab. Add the values highlighted: -Doracle.jdbc.J2EE13Compliant=true is used to make sure the driver behaves in a JEE-compliant manner. View Image To integrate the JDBC driver into a GlassFish Server domain, copy the JAR files into the domain-dir/lib directory, then restart the server. The JAR file for the Oracle 11 database driver is ojdbc6dms.jar. An upcoming entry will demonstrate configuring Glassfish for Oracle ADF Applications.

• Recommended Approach to Secure your ADFdi Spreadsheets

  - by juan.ruiz

  ADF desktop integration leverages ADF security to provide access to published spreadsheets within your application. In this article I discussed a good security practice for your existing as well as any new spreadsheets that you create. ADF Desktop integration uses the adfdiRemoteServlet to process and send request back and fort from and to the ADFmodel which is allocated in the Java EE container where our application is deployed. In other words this is one of the entry points to the application server. Having said that, we need to make sure that container-based security is provided to avoid vulnerabilities. So what is needed? For existing an new ADFdi applications you need to create a Security Constraint for the ADFdi servlet on the Web.xml file of our application. Fortunately JDeveloper 11g provides a nice visual editor to do this. Open the web.xml file and go to the security category Add a new Web Resource Collection give it a meaningful name and on the URL Pattern add /adfdiRemoteServlet click on the Authorization tab and make sure the valid-users  role is selected for authorization and Voila! your application now is more secured.

• Extract High Quality Icons from Files Using a Free Tool

  - by Lori Kaufman

  If you need to extract an icon from a program file or other type of file (such as .dll files), there are many free tools available that make the task easy. However, very few will extract high quality icon images from the files. Most free icon extraction tools will extract smaller icon image sizes, such as 16×16, 32×32, or 48×48 pixels. Some icons come in larger sizes, such as icons used in Windows. There is a free, small utility, called BeCyIconGrabber, that allows you to view and save icons and cursors of any size contained in .exe, .dll, .icl, .ocx, .cpl, .src, .ico, and .cur files. You can save the extracted icons individually as a .png file, .bmp file, .ico file, or .cur file, or in groups within resource libraries, i.e., .dll or .icl files. BeCyIconGrabber can be downloaded as an installable file or as a portable executable that does not need to be installed. We downloaded the portable file.

• Which ecommerce framework is fast and easy to customize?

  - by Diego

  I'm working on a project where I have to put online an ecommerce system which will require some good amount of custom features. I'm therefore looking for a framework which makes customization easy enough (from an experienced developer's perspective, I mean). Language shoul be PHP and time is a constraint, I don't have months to learn. Additionally, the ecommerce will have to handle around 200.000 products from day one, which will increase over time, hence performance is also important. So far I examined the following: Magento - Complicated and, as far as I could read, slow when database contains many products. It's also resource intensive, and we can't afford a dedicated VPS from the beginning. OpenCart - Rough at best, documentation is extremely poor. Also, it's "free" to start, but each feature is implemented via 3rd party commercial modules. OSCommerce - Buggy, inefficient, outdated. ZenCart - Derived from OSCommerce, doesn't seem much better. Prestashop - It looks like it has many incompatibilities. Also, most of its modules are commercial, which increases the cost. In short, I'm still quite undecided, as none of the above seems to satisfy the requirements. I'm open to evaluate closed source frameworks too, if they are any better, but my knowledge about them is limited, therefore I'll welcome any suggestion. Thanks for all replies.

• Instructor Insight: Using the Container Database in Oracle Database 12 c

  - by Breanne Cooley

  The first time I examined the Oracle Database 12c architecture, I wasn’t quite sure what I thought about the Container Database (CDB). In the current release of the Oracle RDBMS, the administrator now has a choice of whether or not to employ a CDB. Bundling Databases Inside One Container In today’s IT industry, consolidation is a common challenge. With potentially hundreds of databases to manage and maintain, an administrator will require a great deal of time and resources to upgrade and patch software. Why not consider deploying a container database to streamline this activity? By “bundling” several databases together inside one container, in the form of a pluggable database, we can save on overhead process resources and CPU time. Furthermore, we can reduce the human effort required for periodically patching and maintaining the software. Minimizing Storage Most IT professionals understand the concept of storage, as in solid state or non-rotating. Let’s take one-to-many databases and “plug” them into ONE designated container database. We can minimize many redundant pieces that would otherwise require separate storage and architecture, as was the case in previous releases of the Oracle RDBMS. The data dictionary can be housed and shared in one CDB, with individual metadata content for each pluggable database. We also won’t need as many background processes either, thus reducing the overhead cost of the CPU resource. Improve Security Levels within Each Pluggable Database  We can now segregate the CDB-administrator role from that of the pluggable-database administrator as well, achieving improved security levels within each pluggable database and within the CDB. And if the administrator chooses to use the non-CDB architecture, everything is backwards compatible, too.  The bottom line: it's a good idea to at least consider using a CDB. -Christopher Andrews, Senior Principal Instructor, Oracle University

• Final Man vs. Machine Round of Jeopardy Unfolds; Watson Dominates

  - by ETC

  The final round of IBM’s Watson against Ken Jenning and Brad Rutter ended last night with Watson coming out in a strong lead against its two human opponents. Read on to catch a video of the match and see just how quick Watson is on the draw. Watson tore through many of the answers, the little probability bar at the bottom of the screen denoting it was often 95%+ confident in its answers. Some of the more interesting stumbles were, like in the last matches, based on nuance. By far the biggest “What?” moment of the night, however, was when it answered the Daily Double question of “The New Yorker’s 1959 review of this said in its brevity and clarity, it is ‘unlike most such manuals, a book as well as a tool’”. Watson, inexplicably, answered “Dorothy Parker”. You can win them all, eh? Check out the video below to see Watson in action on its final day.

  I've been experimenting with s3ql on Ubuntu 10.04, using it to mount Amazon S3 buckets. However, I'd really like it to mount them automatically. Does anyone know how to do that?

• Syslog/kernlog filling up with "did not claim interface N before use"

  - by Wayne Werner

  As I discovered when asking this question, it appears that demond_nscan is trying to use a device without claiming it. And it does it.... hundreds of time per second apparently. This makes kern.log and syslog huge (100GB ). In this particular case the problem is directly a result of some Lexmark drivers that were installed (found at /usr/local/lexmark/unix_scan_drivers/bin/demond_nscan). Here are a few things I know: The drivers are for an all-in-one printer/scanner device. There was a previous lexmark printer-only that was installed with CUPS This driver was the one for CUPS systems, and I think that it automatically added it to the list of printers in CUPS. The issue started spamming kern/syslog only after these drivers were installed, using the lexmark installers While googling around I found this thread that's not completely related, but it does mention that it might be happening when two drivers try to control the same device at the same time. How can I resolve this issue so that either I only have one driver, or get the driver to claim the device before usage?

• 'Content' is NOT 'Text' in XAML

  - by psheriff

  One of the key concepts in XAML is that the Content property of a XAML control like a Button or ComboBoxItem does not have to contain just textual data. In fact, Content can be almost any other XAML that you want. To illustrate here is a simple example of how to spruce up your Button controls in Silverlight. Here is some very simple XAML that consists of two Button controls within a StackPanel on a Silverlight User Control. <StackPanel>  <Button Name="btnHome"          HorizontalAlignment="Left"          Content="Home" />  <Button Name="btnLog"          HorizontalAlignment="Left"          Content="Logs" /></StackPanel> The XAML listed above will produce a Silverlight control within a Browser that looks like Figure 1.   Figure 1: Normal button controls are quite boring. With just a little bit of refactoring to move the button attributes into Styles, we can make the buttons look a little better. I am a big believer in Styles, so I typically create a Resources section within my user control where I can factor out the common attribute settings for a particular set of controls. Here is a Resources section that I added to my Silverlight user control. <UserControl.Resources>  <Style TargetType="Button"         x:Key="NormalButton">    <Setter Property="HorizontalAlignment"            Value="Left" />    <Setter Property="MinWidth"            Value="50" />    <Setter Property="Margin"            Value="10" />  </Style></UserControl.Resources> Now back in the XAML within the Grid control I update the Button controls to use the Style attribute and have each button use the Static Resource called NormalButton. <StackPanel>  <Button Name="btnHome"          Style="{StaticResource NormalButton}"          Content="Home" />  <Button Name="btnLog"          Style="{StaticResource NormalButton}"          Content="Logs" /></StackPanel> With the additional attributes set in the Resources section on the Button, the above XAML will now display the two buttons as shown in Figure 2. Figure 2: Use Resources to Make Buttons More Consistent Now let’s re-design these buttons even more. Instead of using words for each button, let’s replace the Content property to use a picture. As they say… a picture is worth a thousand words, so let’s take advantage of that. Modify each of the Button controls and eliminate the Content attribute and instead, insert an <Image> control with the <Button> and the </Button> tags. Add a ToolTip to still display the words you had before in the Content and you will now have better looking buttons, as shown in Figure 3.   Figure 3: Using pictures instead of words can be an effective method of communication The XAML to produce Figure 3 is shown in the following listing: <StackPanel>  <Button Name="btnHome"          ToolTipService.ToolTip="Home"          Style="{StaticResource NormalButton}">    <Image Style="{StaticResource NormalImage}"            Source="Images/Home.jpg" />  </Button>  <Button Name="btnLog"          ToolTipService.ToolTip="Logs"          Style="{StaticResource NormalButton}">    <Image Style="{StaticResource NormalImage}"            Source="Images/Log.jpg" />  </Button></StackPanel> You will also need to add the following XAML to the User Control’s Resources section. <Style TargetType="Image"        x:Key="NormalImage">  <Setter Property="Width"          Value="50" /></Style> Add Multiple Controls to Content Now, since the Content can be whatever we want, you could also modify the Content of each button to be a StackPanel control. Then you can have an image and text within the button. <StackPanel>  <Button Name="btnHome"          ToolTipService.ToolTip="Home"          Style="{StaticResource NormalButton}">    <StackPanel>      <Image Style="{StaticResource NormalImage}"              Source="Images/Home.jpg" />      <TextBlock Text="Home"                  Style="{StaticResource NormalTextBlock}" />    </StackPanel>  </Button>  <Button Name="btnLog"          ToolTipService.ToolTip="Logs"          Style="{StaticResource NormalButton}">    <StackPanel>      <Image Style="{StaticResource NormalImage}"              Source="Images/Log.jpg" />      <TextBlock Text="Logs"                  Style="{StaticResource NormalTextBlock}" />    </StackPanel>  </Button></StackPanel> You will need to add one more resource for the TextBlock control too. <Style TargetType="TextBlock"        x:Key="NormalTextBlock">  <Setter Property="HorizontalAlignment"          Value="Center" /></Style> All of the above will now produce the following:   Figure 4: Add multiple controls to the content to make your buttons even more interesting. Summary While this is a simple example, you can see how XAML Content has great flexibility. You could add a MediaElement control as the content of a Button and play a video within the Button. Not that you would necessarily do this, but it does work. What is nice about adding different content within the Button control is you still get the Click event and other attributes of a button, but it does necessarily look like a normal button.

• SkyDrive and Consumer Cloud Services

  - by Tim Murphy

  Paul Thurrrott recently posted an article on the future of SkyDrive and I was asked what I thought about its future by @UserCommunity.  So let’s take a look. The breakdown from Microsoft that Paul described I believe is an accurate representation of users and usages. While I can’t say that I leverage SkyDrive to the extent that it was meant to be I do enjoy having OneNote hosted their and being able to consult and edit it from the desktop, web and Windows Phone. Taking that one step further is the Midwest Geeks group which started as the community of Microsoft related user groups in our region uses SkyDrive groups and shares calendars and documents.  This collaboration aspect isn’t new in itself, but having it connected with the rest of your cloud assets makes life easier. Another recent usage of this type of cloud service is storing your personal music files in order to get that same universal access.  This is a scenario that has some arguments for and against.  On the one hand own once and listen anywhere is great, but the on the other hand the bandwidth cost becomes a giant downside.  This is especially the case since most carriers are now doing away with unlimited data packages. Ultimately I see this type of resource growing an evolving at a phenomenal rate over the next few years as we continue to become more mobile.  Having multiple players such as SkyDrive and iCloud will only help to give us more options.  Only time will tell where we end up next. del.icio.us Tags: SkyDrive,Cloud Services,Paul Thurrott,UserCommunity

• Trying to format drive fails

  - by david

  since I will be doing an internship for which i need to use Windows software, I have decided to ruin my day trying to remove my Ubuntu 12.04, install Win XP SP3 (since the DualBoot theme from ubuntu suggests to first install Windows and then Ubuntu, for problems with the bootloader if you do it the other way around) and then reinstall Ubuntu 12.04 since I would like to keep using it as my primary operating system, using WinXP exclusively for the internship. Other than that, I would like to have a partition for the data, which can be used by both Ubuntu and Windows. So now, I have used the disk utility run from an ubuntu-live cd to format my drive with Master Boot Record (being conscious of the fact that this way I will lose all my data, which I have saved on an external drive before, and that my Ubuntu won't work anymore afterwards), creating partitions for Windows (NTFS), personal data (FAT, since as far as I know both Ubuntu and Windows can deal with this), a Swap partition for Linux, and one partition for Ubuntu (ext4); trying to install Win XP from cd gives me a blue screen, which stops the setup and telling me to remove all recently installed drives and to run CHKDSK. So I thought, that maybe Windows doesn't like pre-partitioned drives for its installation and thus I need to re-format my hard drive in order to have a completely "new" drive, which I can then, during the Windows-installation, partition in order to create the partitions I need. Trying to do this, though, the disk-utility run from the live-CD gives me this warning: Error creating partition table: helper exited with exit code 1: In part_create_partition_table: device_file=/dev/sda, scheme=0 got it got disk committed to disk BLKRRPART ioctl failed for /dev/sda: Device or resource busy I do not understand why it tells me that the hard-drive is busy, because, as stated above, I am doing all this from a live-CD. Thus, my questions are: How can I resolve the error given by the disk utility? Does it make sense to use four partitions in the way mentioned above? And if not so, which partitions should I create? Can I, theoretically, partition my drive from an Ubuntu live-cd in order to create the partitions I want and to install first Windows and then Ubuntu? Thanks for any help, David

• Java HttpURLConnection class Program

  - by pandu

  I am learning java. Here is the sample code of HttpURLConnection class usage in some text book import java.net.*; import java.io.*; import java.util.*; class HttpURLDemo { public static void main(String args[]) throws Exception { URL hp = new URL("http://www.google.com"); HttpURLConnection hpCon = (HttpURLConnection) hp.openConnection(); // Display request method. System.out.println("Request method is " + hpCon.getRequestMethod()); // Display response code. System.out.println("Response code is " + hpCon.getResponseCode()); // Display response message. System.out.println("Response Message is " + hpCon.getResponseMessage()); // Get a list of the header fields and a set // of the header keys. Map<String, List<String>> hdrMap = hpCon.getHeaderFields(); Set<String> hdrField = hdrMap.keySet(); System.out.println("\nHere is the header:"); // Display all header keys and values. for(String k : hdrField) { System.out.println("Key: " + k + " Value: " + hdrMap.get(k)); } } } Question is Why hpCon Object is declared in the following way? HttpURLConnection hpCon = (HttpURLConnection) hp.openConnection(); instead of declaring like this HttpURLConnection hpCon = new HttpURLConnection(); Author provided the following explanation. I cant understand Java provides a subclass of URLConnection that provides support for HTTP connections. This class is called HttpURLConnection. You obtain an HttpURLConnection in the same way just shown, by calling openConnection( ) on a URL object, but you must cast the result to HttpURLConnection. (Of course, you must make sure that you are actually opening an HTTP connection.) Once you have obtained a reference to an HttpURLConnection object, you can use any of the methods inherited from URLConnection

• Bad style programming, am I pretending too much?

  - by Luca

  I realized to work in an office with a quite bad code base. The base library implemented in years and years is quite limited, and most of that code is, honestly, horrible. Projects developed in the office are very large. Fine. I could define me a "perfectionist" (but often I'm not), and I thought to refactor an application (really a portion), which need a new (complex) feature. But, today, I really realized that it's not possible to refactor that application modules with a reasonable time (say, 24/26 hours, respect the avaialable time for the task, which is 160 hours). I'm talking about (I am a bit ashamed to say) name collisions, large and frequent cut & paste code, horrible and misleading naming, makefiles without dependencies (!), application login is spread randomly across many different sources, dead code, variable aliasing, no assertion, no documentation, very long source files, bad/incomplete include file definition, (this is emblematic!) very frequent extern declaration of variables and functions, ... I'm sure to continue ... buffer overflows because sprintf, indentation (!), spacing, non existent const modifier usage. I would say that every source line was written quite randomly when needed, without keeping in mind some design (at least, the obvious one). (Am I in hell?) The problem arises when the application is developed by a colleague of mine. I felt very frustrated. So, I decided to expose the "situation" to my colleague; at the end, that was a bad idea. He is justified in saying that "the application was developed in haste, so it is natural that it is written vaguely; you are wasting time to think and implement an elegant implementation" .... I'm asking too much from my colleague to write readable code, which is managed and documented? I expect too much in not having to read thousands of lines of code to understand how a particular logic?

• Planning for the Recovery

  - by john.orourke(at)oracle.com

  As we plan for 2011, there are many positive signs in the global economy, but also some lingering issues. Planning no longer is about extrapolating past performance and adjusting for growth. It is now about constantly testing the temperature of the water, formulating scenarios, assessing risk and assigning probabilities.  So how does one plan for recovery and improve forecast accuracy in such a volatile environment?  Here are some suggestions from a recent article I wrote, which was published in the December Financial Planning & Analysis (FP&A) newsletter from the AFP (Association of Financial Professionals): Increase the frequency of forecasting Get more line managers involved in the planning and forecasting process Re-consider what's being measured - i.e. key financial and operational metrics Incorporate risk and probability into forecasts Reduce reliance on spreadsheets - leverage packaged EPM applications To learn more about these best practices, check out the FP&A section of the AFP website and register to receive the FP&A newsletter.  AFP recently launched a new topic area focused on the FP&A function and items of interest to this group of finance professionals.  In addition to the FP&A quarterly newsletter, AFP will be publishing articles, running webinars and will have an FP&A track in their annual conference, which is in Boston next November.  Brian Kalish, AFP's Finance Lead, is hoping this initiative creates a valuable networking and information-sharing resource for FP&A professionals. Here's a link to the FP&A page on the AFP web site:  http://www.afponline.org/pub/res/topics/topics_fpa.html If you register on the site you can access and subscribe to the FP&A newsletter and other resources. Best of luck in your planning for 2011 and beyond!

• Unit testing ASP.NET Web API controllers that rely on the UrlHelper

  - by cibrax

  UrlHelper is the class you can use in ASP.NET Web API to automatically infer links from the routing table without hardcoding anything. For example, the following code uses the helper to infer the location url for a new resource,public HttpResponseMessage Post(User model) { var response = Request.CreateResponse(HttpStatusCode.Created, user); var link = Url.Link("DefaultApi", new { id = id, controller = "Users" }); response.Headers.Location = new Uri(link); return response; } That code uses a previously defined route “DefaultApi”, which you might configure in the HttpConfiguration object (This is the route generated by default when you create a new Web API project). The problem with UrlHelper is that it requires from some initialization code before you can invoking it from a unit test (for testing the Post method in this example). If you don’t initialize the HttpConfiguration and Request instances associated to the controller from the unit test, it will fail miserably. After digging into the ASP.NET Web API source code a little bit, I could figure out what the requirements for using the UrlHelper are. It relies on the routing table configuration, and a few properties you need to add to the HttpRequestMessage. The following code illustrates what’s needed,var controller = new UserController(); controller.Configuration = new HttpConfiguration(); var route = controller.Configuration.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); var routeData = new HttpRouteData(route, new HttpRouteValueDictionary { { "id", "1" }, { "controller", "Users" } } ); controller.Request = new HttpRequestMessage(HttpMethod.Post, "http://localhost:9091/"); controller.Request.Properties.Add(HttpPropertyKeys.HttpConfigurationKey, controller.Configuration); controller.Request.Properties.Add(HttpPropertyKeys.HttpRouteDataKey, routeData);  The HttpRouteData instance should be initialized with the route values you will use in the controller method (“id” and “controller” in this example). Once you have correctly setup all those properties, you shouldn’t have any problem to use the UrlHelper. There is no need to mock anything else. Enjoy!!.

• Disable the Old Adobe Flash Plugin in Google Chrome

  - by The Geek

  If you’ve just updated to the Dev or Beta release of Google Chrome, you might have noticed that a special version of Adobe Flash is now integrated into the default distribution of Chrome. But what about your old plug-in? As it turns out, the old plug-in is generally still installed… but you can easily disable Chrome plug-ins in the latest version, so let’s get to work. Disable the Extra Flash Plug-in Head over to about:plugins and look through the list—you should notice two Shockwave Flash plugins. The first one should be in your Google Chrome installation folder, and has the filename gcswf32.dll. This is the NEW one, so don’t disable it! If you keep scrollling down, you’ll see the old one, with the file name NPSWF32.dll. This is the OLD plugin, and you can safely disable it. Of course, if you only use Chrome you could just completely uninstall Adobe Flash from your system by heading into Control Panel’s Uninstall Programs screen, and then finding and uninstalling Adobe Flash Player Plugin. The ActiveX version is for Internet Explorer. We’ve not done any testing to see if the old Flash plugin is even still active or not, but may as well disable it just to be sure, right?
