  • Instant Rename and Rename Refactoring

    - by Petr
    During the last weeks I have got  a few questions about rename refactoring and some users also complain to me that the refactoring in NetBeans 6.x was much faster. So I would like to explain the situation. For some people, who don't know, Instant Rename action and Rename Refactoring  can look like one action. But it's not true, even if  both actions use the same shortcut (CTRL + R). NetBeans 6.x contained only Instant Rename action (speaking about PHP support), which we can mark as very simple rename refactoring through one file. From NetBeans 7.0 the Instant Rename action works only in "non public" context. It means that this action is used for fast renaming variables that has local context like inside a method, or for renaming private methods and fields that can not be used outside of the scope, where they are declared. From user point of view these two action can be simply recognized. When is after CTRL+R called Instant Rename action, then the identifier is surrounded with rectangle and you can rename it directly in the file. It's fast and simple, also the usages of this identifier are renamed in the same time as you write. The picture below shows Instant Rename action for $message identifier, that is visible only in the print_test method and due this after CTRL+R is called Instant Rename. In NetBeans 7.0, there was added Rename Refactoring that is called for public identifiers. It means for identifiers that could be used in other files. If you press CTRL+R shortcut when the caret is inside $hello identifier from the picture above, NetBeans recognizes that $hello is declared / used in a global context and calls the Rename Refactoring that brings a dialog to change the name of the identifier. From this dialog you have to preview suggested changes, through pressing Preview button and then execute the refactoring through Do Refactoring button. Yes, it's more complicated from user point of view than Instant Rename, but in Rename Refactoring NetBeans can change more files at once. It should be  the developer responsibility to decide whether the suggested changes are right and the refactoring can be executed or in some files original name should be kept. Someone can argue that he doesn't use $hello variable in any other file so Instant Rename could be used in such case. Yes it's true, but in such case NetBeans has to know all usages of all identifiers and keep this informations up to date during editing a file. I'm sure that this is not possible due to the performance problems, mainly for big projects. So the usages are computed after pressing the Preview button. And why is the Refactor button always disabled in the Rename dialog and user has to always go through the preview phase? NetBeans has API and SPI for implementing refactoring actions and this dialog is a part of this infrastructure. If you rename an identifier for example in Java, the Refactor buttons is enabled, but Java is strongly type language and you can be almost in 99% sure that the IDE will suggest the right results. In PHP as a dynamic language, we can not be sure, what NetBeans finds is only a "guess". This is why NetBeans pushes developers to preview the changes for PHP rename. I hope that I have explain it clearly. I'm open to any discussion. What I have described above is situation in NetBeans 7.0, 7.0.1 and probably it will be also in NetBeans 7.1, because there is no plan to change it. Please write your opinion here.

  • Failure Sucks, But Does It Have To?

    - by steve.diamond
    Hey Folks--It's "elephant in the room" time. Imagine a representative from a CRM VENDOR discussing CRM FAILURES. Well. I recently saw this blog post from Michael Krigsman on "six ways CRM projects go wrong." Now, I know this may come off defensive, but my comments apply to ALL CRM vendors, not just Oracle. As I perused the list, I couldn't find any failures related to technology. They all seemed related to people or process. Now, this isn't about finger pointing, or impugning customers. I love customers! And when they fail, WE fail. Although I sit in the cheap seats, i.e., I haven't funded any multi-million dollar CRM initiatives lately, I kept wondering how to convert the perception of failure as something that ends and is never to be mentioned again (see Michael's reason #4), to something that one learns from and builds upon. So to continue my tradition of speaking in platitudes, let me propose the following three tenets: 1) Try and get ahead of your failures while they're very very small. 2) Immediately assess what you can learn from those failures. 3) With more than 15 years of CRM deployments, seek out those vendors that have a track record both in learning from "misses" and in supporting MANY THOUSANDS of CRM successes at companies of all types and sizes. Now let me digress briefly with an unpleasant (for me, anyway) analogy. I really don't like flying. Call it 'fear of dying' or 'fear of no control.' Whatever! I've spoken with quite a few commercial pilots over the years, and they reassure me that there are multiple failures on most every flight. We as passengers just don't know about them. Most of them are too miniscule to make a difference, and most of them are "caught" before they become LARGER failures. It's typically the mid-sized to colossal failures we hear about, and a significant percentage of those are due to human error. What's the point? I'd propose that organizations consider the topic of FAILURE in five grades. On one end, FAILURE Grade 1 is a minor/miniscule failure. On the other end, FAILURE Grade 5 is a colossal failure A Grade 1 CRM FAILURE could be that a particular interim milestone was missed. Why? What can we learn from that? How can we prevent that from happening as we proceed through the project? Individual organizations will need to define their own Grade 2 and Grade 3 failures. The opportunity is to keep those Grade 3 failures from escalating any further. Because honestly, a GRADE 5 failure may not be recoverable. It could result in a project being pulled, countless amounts of hours and dollars lost, and jobs lost. We don't want to go there. In closing, I want to thank Michael for opening my eyes up to the world of "color," versus thinking of failure as both "black and white" and a dead end road that organizations can't learn from and avoid discussing like the plague.

  • Mandatory look back at 2010

    - by Bertrand Le Roy
    Yeah, it's one of those posts, sorry. First, the mildly depressing: the most popular post on this blog this year with 47,000 hits was a post from last year about a fix to a bug in ASP.NET. A content-less post except for that link to the KB article that people should have found by going directly to the support site in the first place. Then, the really depressing: the second most popular post this year with 34,000 hits was a post from 2005 about how to display message boxes on a web page. I mean come on. This was kind of fun five years ago and it did solve one of the most common n00b mistakes VB programmers trying to move to the web were making. But come on, we've traveled about 4.7 billion miles around the Earth since then. Do people still do that kind of stuff? I should probably put a big red banner on top of this post. Oh [supernatural entity of your choice]. Hand me that gun, please. Third most popular post with 24,000 hits is from 2004. It's about how to set a session variable before redirecting. That problem has been fixed a long time ago. Oh well. Fourth most popular post. 21,000 hits. 2007. How to work around a stupid bug in ASP.NET Ajax 1.0. Fixed in ASP.NET 3.5? ASP.NET Ajax 1.0? Need I say more? The fifth one (20,000 hits) is an old post as well but I'm kind of fond of it: it's about that photo album handler I've been organically growing for a few years. It reminds me that I need to refresh it and make a new release. Good SEO title too. Back to insanity with the sixth one (16,000) that's about working around a bug in IE6. IE6. Please just refuse to pander to that browser any more. It's about time. Let's move on, please. Actually, the first post from 2010 is 15th in the list. We have a trio of these actually with server-side image resizing and FluentPath. So what happened? Well, I like the ad money, but not to the point that I'm going to write my stuff to inflate it. Actually I think if I tried I would fail miserably (I mean, I would fail worse). What really happened this year was new stuff: Orchard, FluentPath and the stuff with the Netduino. That stuff needs time to get off the ground but my hope is that it's going to be useful in the long run and that five years from now I'll be lamenting on how well those posts are still doing. So, no regret. 2010 was a good year. Oh, and I was on This Developer's Life this year! Yay! Anyways, thank you all for reading me. Please continue doing that. And happy 2011!

  • How to set default xrandr settings?

    - by echo-flow
    I'm trying to enable dual monitors in Ubuntu. This is working fine, but every time I do it, desktop effects is disabled. I think I've found the reason why, though: https://wiki.ubuntu.com/X/Config/Multihead/ As with the GNOME XRandR configuration method, setting Virtual to too large a value may result in a loss of hardware acceleration, and thus an inability to use Compiz and its desktop effects. When I use the GNOME monitor applet, or the Monitors configuration in the System menu, the default xrandr settings puts the second monitor to the right of the first, and, as I found with this bug, for most monitors this creates a virtual desktop larger than the maximum 2048 horizontal resolution needed for hardware acceleration on my netbook hardware. So, it seems like if I can modify xrandr's default settings so that it places the new desktop above or below (north or south of) the main LVDS display, then hardware acceleration, and therefore compiz will continue to work. Can anyone tell me, what is the easiest way to achieve this? UPDATE: I have confirmed that multihead support with desktop effects and hardware acceleration works when I move the external monitor display north of the main LVDS display. Right now this involves the following process: plugging in the external monitor, starting the Monitors configuration menu, desktop effects are disabled automatically (and all of the windows on my workspaces are moved to the first workspace), repositioning the external display so that it is north of LVDS display and clicking apply, and then navigating to the Appearance menu and telling it to reenable desktop effects. Is there a simpler way do this? UPDATE 2: OK, so I thought that perhaps the GNOME Monitors configuration screen was trying to be clever, and might be disbling desktop effects. So, I just tried using the xrandr command-line client instead, as follows: xrandr --output VGA1 --above LVDS1 When I do that, desktop effects are still disabled, and I need to manually reenable them. This, despite the fact that hardware acceleration works, and there is never a point where hardware acceleration stops working because the horizontal dimension of the virtual display is too large. So what program is trying to be clever, and is turning off desktop effects when it doesn't need to? And how do I make it stop? If there were a way to re-enable desktop effects from the command line, which I could then put into a script along with the proper xrandr invocation, I would accept that as a workaround. UPDATE 3: OK, here's my script to enable a second monitor with desktop effects. It might be evil, I'm not sure: second-monitor.sh xrandr --output VGA1 --above LVDS1 sleep 3 compiz --replace & The sleep statement might not be necessary. If there's a better way to do this, please let me know. UPDATE 4: This is a Dell Mini Inspiron 1012.

  • Is this simple XOR encrypted communication absolutely secure?

    - by user3123061
    Say Alice have 4GB USB flash memory and Peter also have 4GB USB flash memory. They once meet and save on both of memories two files named alice_to_peter.key (2GB) and peter_to_alice.key (2GB) which is randomly generated bits. Then they never meet again and communicate electronicaly. Alice also maintains variable called alice_pointer and Peter maintains variable called peter_pointer which is both initially set to zero. Then when Alice needs to send message to Peter they do: encrypted_message_to_peter[n] = message_to_peter[n] XOR alice_to_peter.key[alice_pointer + n] Where n i n-th byte of message. Then alice_pointer is attached at begining of the encrypted message and (alice_pointer + encrypted message) is sent to Peter and then alice_pointer is incremented by length of message (and for maximum security can be used part of key erased) Peter receives encrypted_message, reads alice_pointer stored at beginning of message and do this: message_to_peter[n] = encrypted_message_to_peter[n] XOR alice_to_peter.key[alice_pointer + n] And for maximum security after reading of message also erases used part of key. - EDIT: In fact this step with this simple algorithm (without integrity check and authentication) decreases security, see Paulo Ebermann post below. When Peter needs to send message to Alice they do analogical steps with peter_to_alice.key and with peter_pointer. With this trivial schema they can send for next 50 years each day 2GB / (50 * 365) = cca 115kB of encrypted data in both directions. If they need more data to send, they simple use larger memory for keys for example with today 2TB harddiscs (1TB keys) is possible to exchange next 50years 60MB/day ! (thats practicaly lots of data for example with using compression its more than hour of high quality voice communication) It Seems to me there is no way for attacker to read encrypted message without keys even if they have infinitely fast computer. because even with infinitely fast computer with brute force they get ever possible message that can fit to length of message, but this is astronomical amount of messages and attacker dont know which of them is actual message. I am right? Is this communication schema really absolutely secure? And if its secure, has this communication method its own name? (I mean XOR encryption is well-known, but whats name of this concrete practical application with use large memories at both communication sides for keys? I am humbly expecting that this application has been invented someone before me :-) ) Note: If its absolutely secure then its amazing because with today low cost large memories it is practicaly much cheeper way of secure communication than expensive quantum cryptography and with equivalent security! EDIT: I think it will be more and more practical in future with lower a lower cost of memories. It can solve secure communication forever. Today you have no certainty if someone succesfuly atack to existing ciphers one year later and make its often expensive implementations unsecure. In many cases before comunication exist step where communicating sides meets personaly, thats time to generate large keys. I think its perfect for military communication for example for communication with submarines which can have installed harddrive with large keys and military central can have harddrive for each submarine they have. It can be also practical in everyday life for example for control your bank account because when you create your account you meet with bank etc.

  • Recent improvements in Console Performance

    - by loren.konkus
    Recently, the WebLogic Server development and support organizations have worked with a number of customers to quantify and improve the performance of the Administration Console in large, distributed configurations where there is significant latency in the communications between the administration server and managed servers. These improvements fall into two categories: Constraining the amount of time that the Console stalls waiting for communication Reducing and streamlining the amount of data required for an update A few releases ago, we added support for a configurable domain-wide mbean "Invocation Timeout" value on the Console's configuration: general, advanced section for a domain. The default value for this setting is 0, which means wait indefinitely and was chosen for compatibility with the behavior of previous releases. This configuration setting applies to all mbean communications between the admin server and managed servers, and is the first line of defense against being blocked by a stalled or completely overloaded managed server. Each site should choose an appropriate timeout value for their environment and network latency. In the next release of WebLogic Server, we've added an additional console preference, "Management Operation Timeout", to the Console's shared preference page. This setting further constrains how long certain console pages will wait for slowly responding servers before returning partial results. While not all Console pages support this yet, key pages such as the Servers Configuration and Control table pages and the Deployments Control pages have been updated to support this. For example, if a user requests a Servers Table page and a Management Operation Timeout occurs, the table is displayed with both local configuration and remote runtime information from the responding managed servers and only local configuration information for servers that did not yet respond. This means that a troublesome managed server does not impede your ability to manage your domain using the Console. To support these changes, these Console pages have been re-written to use the Work Management feature of WebLogic Server to interact with each server or deployment concurrently, which further improves the responsiveness of these pages. The basic algorithm for these pages is: For each configuration mbean (ie, Servers) populate rows with configuration attributes from the fast, local mbean server Find a WorkManager For each server, Create a Work instance to obtain runtime mbean attributes for the server Schedule Work instance in the WorkManager Call WorkManager.waitForAll to wait WorkItems to finish, constrained by Management Operation Timeout For each WorkItem, if the runtime information obtained was not complete, add a message indicating which server has incomplete data Display collected data in table In addition to these changes to constrain how long the console waits for communication, a number of other changes have been made to reduce the amount and scope of managed server interactions for key pages. For example, in previous releases the Deployments Control table looked at the status of a deployment on every managed server, even those servers that the deployment was not currently targeted on. (This was done to handle an edge case where a deployment's target configuration was changed while it remained running on previously targeted servers.) We decided supporting that edge case did not warrant the performance impact for all, and instead only look at the status of a deployment on the servers it is targeted to. Comprehensive status continues to be available if a user clicks on the 'status' field for a deployment. Finally, changes have been made to the System Status portlet to reduce its impact on Console page display times. Obtaining health information for this display requires several mbean interactions with managed servers. In previous releases, this mbean interaction occurred with every display, and any delay or impediment in these interactions was reflected in the display time for every page. To reduce this impact, we've made several changes in this portlet: Using Work Management to obtain health concurrently Applying the operation timeout configuration to constrain how long we will wait Caching health information to reduce the cost during rapid navigation from page to page and only obtaining new health information if the previous information is over 30 seconds old. Eliminating heath collection if this portlet is minimized. Together, these Console changes have resulted in significant performance improvements for the customers with large configurations and high latency that we have worked with during their development, and some lesser performance improvements for those with small configurations and very fast networks. These changes will be included in the 11g Rel 1 patch set 2 (10.3.3.0) release of WebLogic Server.

  • #iPad at One Week: A Great Device Made with a Heavy Hand

    - by andrewbrust
    I have now had my iPad for a little over a week. In that time, Apple introduced the world to its iPhone OS 4 (and the SDK agreement’s draconian new section 3.3.1), HP introduced is Slate, and Microsoft got ready to launch Visual Studio 2010 and .NET 4.0. And through it all I have used my iPad. I've used it for email, calendar, controlling my Sonos, and writing an essay. I've used it for getting on TripIt and Twitter, and surfing the Web. I've used it for online banking, and online ordering and delivery of food. And the verdict? Honestly? I think it's a great device and I thoroughly enjoy using it. The screen is bright and vibrant. I am surprisingly fast and accurate when I type on it. The touch screen's responsiveness is nearly flawless. The software, including a number of third party applications, include pleasing animations and use of color that make it fun to get work done. And speaking of work, the Exchange integration is, dare I say it, robust. Not as full-featured as on a PC or Windows Mobile device, but still offering core functionality and, so far at least, without bugs. The UI is intuitive, not just to me, but also to my 5 1/2 year old, and also to my nearly-3-year-old son. They picked it up and, with just just a few pointers from me, they almost immediately knew what to do, whether they were looking at photos (and swiping/flicking along as they did so), using a drawing program, playing a game, or watching YouTube videos. The younger of the two of them even tried to get up on a chair and grab the thing today. He dropped it, from about 4 feet off the ground. And it's still fine. (Meanwhile, I'll be keeping it on a higher shelf.) I cannot fully describe yet what makes this form factor and this product so appealing. Maybe it's that it's an always-on device. Maybe it's just being able to hold such a nice, relatively large display so close. Maybe it's the design sensibility, that seems to pervade throughout the app ecosystem. Or maybe it's that one's fingers, and not pens or mice, are the software's preferred input device. Whatever the attraction, it's strong. And no matter how much I tend to root for Microsoft and against Apple, Cupertino has, in my mind, scored big, Can Microsoft compete? Yes, but not with the Windows 7 standard UI (nor with individual OEMs’ own UIs on top). I hope Microsoft builds a variant of the Windows Phone 7 specifically for tablet devices. And I hope they make it clear that all developers, and programming languages, are welcome to the platform. Once that’s established, the OEMs have to build great hardware with fast, responsive touch screens, under Microsoft's watchful eye. That may be the hardest part of getting this right. No matter what, Microsoft's got a fight on its hands. I don't know if it can count on winning that fight, either. But Silverlight and Live Tiles could certainly help. And so can treating developers like adults.  Apple seems intent on treating their devs like kids, and then giving the kids a curfew.  For that, dev-friendly Microsoft may one day give thanks.

  • SQL analytical mash-ups deliver real-time WOW! for big data

    - by KLaker
    One of the overlooked capabilities of SQL as an analysis engine, because we all just take it for granted, is that you can mix and match analytical features to create some amazing mash-ups. As we move into the exciting world of big data these mash-ups can really deliver those "wow, I never knew that" moments. While Java is an incredibly flexible and powerful framework for managing big data there are some significant challenges in using Java and MapReduce to drive your analysis to create these "wow" discoveries. One of these "wow" moments was demonstrated at this year's OpenWorld during Andy Mendelsohn's general keynote session.  Here is the scenario - we are looking for fraudulent activities in our big data stream and in this case we identifying potentially fraudulent activities by looking for specific patterns. We using geospatial tagging of each transaction so we can create a real-time fraud-map for our business users. Where we start to move towards a "wow" moment is to extend this basic use of spatial and pattern matching, as shown in the above dashboard screen, to incorporate spatial analytics within the SQL pattern matching clause. This will allow us to compute the distance between transactions. Apologies for the quality of this screenshot….hopefully below you see where we have extended our SQL pattern matching clause to use location of each transaction and to calculate the distance between each transaction: This allows us to compare the time of the last transaction with the time of the current transaction and see if the distance between the two points is possible given the time frame. Obviously if I buy something in Florida from my favourite bike store (may be a new carbon saddle for my Trek) and then 5 minutes later the system sees my credit card details being used in Arizona there is high probability that this transaction in Arizona is actually fraudulent (I am fast on my Trek but not that fast!) and we can flag this up in real-time on our dashboard: In this post I have used the term "real-time" a couple of times and this is an important point and one of the key reasons why SQL really is the only language to use if you want to analyse  big data. One of the most important questions that comes up in every big data project is: how do we do analysis? Many enlightened customers are now realising that using Java-MapReduce to deliver analysis does not result in "wow" moments. These "wow" moments only come with SQL because it is offers a much richer environment, it is simpler to use and it is faster - which makes it possible to deliver real-time "Wow!". Below is a slide from Andy's session showing the results of a comparison of Java-MapReduce vs. SQL pattern matching to deliver our "wow" moment during our live demo.  You can watch our analytical mash-up "Wow" demo that compares the power of 12c SQL pattern matching + spatial analytics vs. Java-MapReduce  here: You can get more information about SQL Pattern Matching on our SQL Analytics home page on OTN, see here http://www.oracle.com/technetwork/database/bi-datawarehousing/sql-analytics-index-1984365.html.  You can get more information about our spatial analytics here: http://www.oracle.com/technetwork/database-options/spatialandgraph/overview/index.html If you would like to watch the full Database 12c OOW presentation see here: http://medianetwork.oracle.com/video/player/2686974264001

  • wifi hardware switch doesn't work on a Dell 1018

    - by user42566
    I have a problem with my Dell 1018 Inspiron. I can't switch the wifi on, through the key on the keyboard. I think it's a driver problem since Ubuntu 11.10. This are the versions i tried: Ubuntu 10.04 / 10.10 It's possible to install the driver by hand: sudo add-apt-repository ppa:lexical/hwe-wireless sudo apt-get update sudo apt-get install rtl8192ce-dkms Ubuntu 11.04 It works out of the box Ubuntu 11.10 / 12.04 I haven’t found any solution for these versions. The "ppa:lexical/hwe-wireless" doesn't work for these versions. It says Can not find package rtl8192ce-dkms. The window of additional drivers is empty. So I can't install the driver.

  • Taking a screenshot from within a Silverlight #WP7 application

    - by Laurent Bugnion
    Often times, you want to take a screenshot of an application’s page. There can be multiple reasons. For instance, you can use this to provide an easy feedback method to beta testers. I find this super invaluable when working on integration of design in an app, and the user can take quick screenshots, attach them to an email and send them to me directly from the Windows Phone device. However, the same mechanism can also be used to provide screenshots are a feature of the app, for example if the user wants to save the current status of his application, etc. Caveats Note the following: The code requires an XNA library to save the picture to the media library. To have this, follow the steps: In your application (or class library), add a reference to Microsoft.Xna.Framework. In your code, add a “using” statement to Microsoft.Xna.Framework.Media. In the Properties folder, open WMAppManifest.xml and add the following capability: ID_CAP_MEDIALIB. The method call will fail with an exception if the device is connected to the Zune application on the PC. To avoid this, either disconnect the device when testing, or end the Zune application on the PC. While the method call will not fail on the emulator, there is no way to access the media library, so it is pretty much useless on this platform. This method only prints Silverlight elements to the output image. Other elements (such as a WebBrowser control’s content for instance) will output a black rectangle. The code public static void SaveToMediaLibrary( FrameworkElement element, string title) { try { var bmp = new WriteableBitmap(element, null); var ms = new MemoryStream(); bmp.SaveJpeg( ms, (int)element.ActualWidth, (int)element.ActualHeight, 0, 100); ms.Seek(0, SeekOrigin.Begin); var lib = new MediaLibrary(); var filePath = string.Format(title + ".jpg"); lib.SavePicture(filePath, ms); MessageBox.Show( "Saved in your media library!", "Done", MessageBoxButton.OK); } catch { MessageBox.Show( "There was an error. Please disconnect your phone from the computer before saving.", "Cannot save", MessageBoxButton.OK); } } This method can save any FrameworkElement. Typically I use it to save a whole page, but you can pass any other element to it. On line 7, we create a new WriteableBitmap. This excellent class can render a visual tree into a bitmap. Note that for even more features, you can use the great WriteableBitmapEx class library (which is open source). On lines 9 to 16, we save the WriteableBitmap to a MemoryStream. The only format supported by default is JPEG, however it is possible to convert to other formats with the ImageTools library (also open source). Lines 18 to 20 save the picture to the Windows Phone device’s media library. Using the image To retrieve the image, simply launch the Pictures library on the phone. The image will be in Saved Pictures. From here, you can share the image (by email, for instance), or synchronize it with the PC using the Zune software. Saving to other platforms It is of course possible to save to other platforms than the media library. For example, you can send the image to a web service, or save it to the isolated storage on the device. To do this, instead of using a MemoryStream, you can use any other stream (such as a web request stream, or a file stream) and save to that instead. Hopefully this code will be helpful to you!

  • IE9 and the Mystery of the Broken Video Tag

    - by David Wesst
    I was very excited when Microsoft released the Internet Explorer 9 Release Candidate. As far as I was concerned, this was another nail in the coffin for IE6 and step in the right direction for us .NET web developers as our base camp was finally starting to support the latest and greatest future-web standards. Unfortunately, my celebration was short lived as I soon hit a snag while loading up an HTML5 site I was building in Visual Studio 2010. The Mystery After updating Internet Explorer, I ran my HTML5 site that had the oh-so-lovely HTML5 video tag showing a video. Even though this worked in IE9 Beta, it appeared that IE9 RC could not load the same file. I figured that it was the video codec. Maybe IE9 RC no longer supported the video codec I used to encode my video. Here's the code I used: <video width="854" height="480" id="myOtherVideo" autoplay="" controls=""> <source src="/DemoSite1/Media/big_buck_bunny.mp4"/> <div> <p>Your browser does not support HTML5 Video.</p> </div> </video> As you can see from the code, I had the "fail-safe" code inside the video tag. The idea there being that if the video tag, or the video files themselves, are not supported by the browser my video should fail gracefully. What was even more strange was the fact that it worked in all the other HTML5 browsers that supported video. The Investigation Whoa! DJ stop the music. How can any of that make sense? Would the IE team really take such huge strides forward only to forget to include a feature that was already in the beta? I don't think so. I did plenty of searching on the web and asking around on the web, but could not seem to find anyone else having the same problem. Eventually I came across this post talking about declaring the MIME type in the .htaccess file. That got me thinking: does my web server support the video MIME type? I was using VS2010, so how do I know what kind of MIME types are supported by default? Still, my page hosted in Cassini (the web development server in VS2010) works on the other browsers. Why wouldn't it work with IE9 RC? To answer that, it was time to open up the upgraded toolbox known as the Developer's Tools in IE9 and use the new Network Tab. The Conclusion If you take a closer look at the results displayed from the Network tab, you can see that IE9 RC has interpreted the video file as text/html rather than video/mp4. To make this work, I decided to use IIS to debug my HTML5 web application by setting the web project's properties. Then, I added the MIME types that I want to support (i.e. video/mp4, video/ogg, video/webm). Et voila! The Mystery of the Broken Video Tag is solved. After Thoughts After solving the mystery, I still had the question about why my site worked in Chrome, Safari, and Firefox 3.6. After asking around, the best answer that I received was from my colleague Tyler Doerksen. He said that IE9 likely depends on the server telling it what kind of file it is downloading rather than trying to read the metadata about the data it is trying to download before doing anything. I have no facts to back this up, but it makes sense to me. In a browser war where milliseconds can make your browser fall back a few places in the race for supremacy, maybe the IE team opted to depend on the server knowing what kind of content it is serving up. Makes sense to me. In any case, that is just an educated guess. If you have any comments, feel free to post on them below. This post also appears at http://david.wes.st

  • Are Chief Digital Officers the Result of CMO/CIO Refusal to Change?

    - by Mike Stiles
    Apparently CDO no longer just stands for “Collateralized Debt Obligations.”  It stands for Chief Digital Officer. And they’re the ones who are supposed to answer the bat signal CEO’s are throwing into the sky, swoop in and POW! drive the transition of the enterprise to integrated digital systems. So imagine being a CMO or a CIO at such an enterprise and realizing it’s been determined that you are not the answer that’s needed. In fact, IntelligentHQ author Ashley Friedlein points out the very rise of the CDO is an admission of C-Suite failure to become savvy enough, quickly enough in modern technology. Is that fair? Despite the repeated drumbeat that CMO’s and CIO’s must enter a new era of cooperation and collaboration to enact the social-enabled enterprise, the verdict seems to be that if it’s happening at all, it’s not happening fast enough. Therefore, someone else is needed with the authority to make things happen. So who is this relatively new beast? Gartner VP David Willis says, “The Chief Digital Officer plays in the place where the enterprise meets the customer, where the revenue is generated, and the mission accomplished.” In other words, where the rubber meets the road. They aren’t just another “C” heading up a unit. They’re the CEO’s personal SWAT team, able to call the shots necessary across all units to affect what has become job one…customer experience. And what are the CMO’s and CIO’s doing while this is going on? Playing corporate games. Accenture reports 38% of CMOs say IT deliberately keeps them out of the loop, with 35% saying marketing’s needs aren’t a very high priority. 31% of CIOs say marketers don’t understand tech and regularly go around them for solutions. Fun! Meanwhile the CEO feels the need to bring in a parental figure to pull it all together. Gartner thinks 25% of all orgs will have a CDO by 2015 as CMO’s and particularly CIO’s (Peter Hinssen points out many CDO’s are coming “from anywhere but IT”) let the opportunity to be the agent of change their company needs slip away. Perhaps most interestingly, these CDO’s seem to be entering the picture already on the fast track. One consultancy counted 7 instances of a CDO moving into the CEO role, which, as this Wired article points out, is pretty astounding since nobody ever heard of the job a few years ago. And vendors are quickly figuring out that this is the person they need to be talking to inside the brand. The position isn’t without its critics. Forrester’s Martin Gill says the reaction from executives at some traditional companies to someone being brought in to be in charge of digital might be to wash their own hands of responsibility for all things digital – a risky maneuver given the pervasiveness of digital in business. They might not even be called Chief Digital Officers. They might be the Chief Customer Officer, Chief Experience Officer, etc. You can call them Twinkletoes if you want to, but essentially anyone who has the mandate direct from the CEO to enact modern technology changes not currently being championed by the CMO or CIO can be regarded as “boss.” @mikestiles @oraclesocialPhoto: freedigitalphotos.net

  • How to Speed Up Any Android Phone By Disabling Animations

    - by Chris Hoffman
    Android phones — and tablets, too — display animations when moving between apps and screens. These animations look very slick, but they waste time — especially on fast phones, which could switch between apps instantly if not for the animations. Disabling these animations will speed up navigating between different apps and interface screens on your phone, saving you time. You can also speed up the animations if you’d rather see them. Access the Developer Options Menu First, we’ll need to access the Developer Options menu. It’s hidden by default so Android users won’t stumble across it unless they’re actually looking for it. To access the Developer Options menu, open the Settings screen, scroll down to the bottom of the list, and tap the About phone or About tablet option. Scroll down to the Build number field and tap it repeatedly. Eventually, you’ll see a message appear saying “You are now a developer!”. The Developer options submenu now appears on the Settings screen. You’ll find it near the bottom of the list, just above the About phone or About tablet option. Disable Interface Animations Open the Developer Options screen and slide the switch at the top of the screen to On. This allows you to change the hidden options on this screen. If you ever want to re-enable the animations and revert your changes, all you have to do is slide the Developer Options switch back to Off. Scroll down to the Drawing section. You’ll find the three options we want here — Window animation scale, Transition animation scale, and Animator duration scale. Tap each option and set it to Animation off to disable the associated animations. If you’d like to speed up the animations without disabling them entirely, select the Animation .5x option instead. If you’re feeling really crazy, you can even select longer animation durations. You can make the animations take as much as ten times longer with the Animation 10x setting. The Animator duration scale option applies to the transition animation that appears when you tap the app drawer button on your home screen.  Your change here won’t take effect immediately — you’ll have to restart Android’s launcher after changing the Animator duration scale setting. To restart Android’s launcher, open the Settings screen, tap Apps, swipe over to the All category, scroll down, and tap the Launcher app. Tap the Force stop button to forcibly close the launcher, then tap your device’s home button to re-launch the launcher. Your app drawer will now open immediately, too. Now whenever you open an app or transition to a new screen, it will pop up as quickly as possible — no waiting for animations and wasting processing power rendering them. How much of a speed improvement you’ll see here depends on your Android device and how fast it is. On our Nexus 4, this change makes many apps appear and become usable instantly if they’re running in the background. If you have a slower device, you may have to wait a moment for apps to be usable. That’s one of the big reasons why Android and other operating systems use animations. Animations help paper over delays that can occur while the operating system loads the app.

  • Dell 3721 Wifi problem Ubuntu 13.04

    I have a Dell 3721 which comes original with windows 8. I managed it to install ubuntu 12.10 on this laptop, even there was no out of the box drivers. With 12.10 I was forces to install this .deb package couple of times. After installing it, it was ok for some weeks before I have to install it again. Maybe some security updates destroy something which made in necessary to install it again... http://jas.gemnetworks.com/debian/pool/main/w/wireless-bcm43142/wireless-bcm43142-dkms_6.20.55.19-1_amd64.deb My problem is, that this package isnt working with ubuntu 13.04 anymore. So I cant use Wifi now. Also my display is almost dark, I cant change the brightness level with ubuntu 13.04. Hope you can give me some advice.

  • WebLogic Server Performance and Tuning: Part II - Thread Management

    - by Gokhan Gungor
    WebLogic Server, like any other java application server, provides resources so that your applications use them to provide services. Unfortunately none of these resources are unlimited and they must be managed carefully. One of these resources is threads which are pooled to provide better throughput and performance along with the fast response time and to avoid deadlocks. Threads are execution points that WebLogic Server delivers its power and execute work. Managing threads is very important because it may affect the overall performance of the entire system. In previous releases of WebLogic Server 9.0 we had multiple execute queues and user defined thread pools. There were different queues for different type of work which had fixed number of execute threads.  Tuning of this thread pools and finding the proper number of threads was time consuming which required many trials. WebLogic Server 9.0 and the following releases use a single thread pool and a single priority-based execute queue. All type of work is executed in this single thread pool. Its size (thread count) is automatically decreased or increased (self-tuned). The new “self-tuning” system simplifies getting the proper number of threads and utilizing them.Work manager allows your applications to run concurrently in multiple threads. Work manager is a mechanism that allows you to manage and utilize threads and create rules/guidelines to follow when assigning requests to threads. We can set a scheduling guideline or priority a request with a work manager and then associate this work manager with one or more applications. At run-time, WebLogic Server uses these guidelines to assign pending work/requests to execution threads. The position of a request in the execute queue is determined by its priority. There is a default work manager that is provided. The default work manager should be sufficient for most applications. However there can be cases you want to change this default configuration. Your application(s) may be providing services that need mixture of fast response time and long running processes like batch updates. However wrong configuration of work managers can lead a performance penalty while expecting improvement.We can define/configure work managers at;•    Domain Level: config.xml•    Application Level: weblogic-application.xml •    Component Level: weblogic-ejb-jar.xml or weblogic.xml(For a specific web application use weblogic.xml)We can use the following predefined rules/constraints to manage the work;•    Fair Share Request Class: Specifies the average thread-use time required to process requests. The default is 50.•    Response Time Request Class: Specifies a response time goal in milliseconds.•    Context Request Class: Assigns request classes to requests based on context information.•    Min Threads Constraint: Limits the number of concurrent threads executing requests.•    Max Threads Constraint: Guarantees the number of threads the server will allocate to requests.•    Capacity Constraint: Causes the server to reject requests only when it has reached its capacity. Let’s create a work manager for our application for a long running work.Go to WebLogic console and select Environment | Work Managers from the domain structure tree. Click New button and select Work manager and click next. Enter the name for the work manager and click next. Then select the managed server instances(s) or clusters from available targets (the one that your long running application is deployed) and finish. Click on MyWorkManager, and open the Configuration tab and check Ignore Stuck Threads and save. This will prevent WebLogic to tread long running processes (that is taking more than a specified time) as stuck and enable to finish the process.

  • SSIS Debugging Tip: Using Data Viewers

    - by Jim Giercyk
    When you have an SSIS package error, it is often very helpful to see the data records that are causing the problem.  After all, if your input has 50,000 records and 1 of them has corrupt data, it can be a chore.  Your execution results will tell you which column contains the bad data, but not which record…..enter the Data Viewer. In this scenario I have created a truncation error.  The input length of [lastname] is 50, but the output table has a length of 15.  When it runs, at least one of the records causes the package to fail.     Now what?  We can tell from our execution results that there is a problem with [lastname], but we have no idea WHICH record?     Let’s identify the row that is actually causing the problem.  First, we grab the oft’ forgotten Row Count shape from our toolbar and connect it to the error output from our input query.  Remember that in order to intercept errors with the error output, you must redirect them.     The Row Count shape requires 1 integer variable.  For our purposes, we will not reference the variable, but it is still required in order for the package to run.  Typically we would use the variable to hold the number of rows in the table and refer back to it later in our process.  We are simply using the Row Count as a “Dead End” for errors.  I called my variable RowCounter.  To create a variable, with no shapes selected, right-click on the background and choose Variable.     Once we have setup the Row Count shape, we can right-click on the red line (error output) from the query, and select Data Viewers.  In the popup, we click the add button and we will see this:     There are other fancier options we can play with, but for now we just want to view the output in a grid.  WE select Grid, then click OK on all of the popup windows to shut them down.  We should now see a grid with a pair of glasses on the error output line.     So, we are ready to catch the error output in a grid and see that is causing the problem!  This time when we run the package, it does not fail because we directed the error to the Row Count.  We also get a popup window showing the error record in a grid.  If there were multiple errors we would see them all.     Indeed, the [lastname] column is longer than 15 characters.  Notice the last column in the grid, [Error Code – Description].  We knew this was a truncation error before we added the grid, but if you have worked with SSIS for any length of time, you know that some errors are much more obscure.  The description column can be very useful under those circumstances! Data viewers can be used any time we want to see the data that is actually in the pipeline;  they stop the package temporarily until we shut them.  Also remember that the Row Count shape can be used as a “Dead End”.  It is useful during development when we want to see the output from a dataflow, but don’t want to update a table or file with the data.  Data viewers are an invaluable tool for both development and debugging.  Just remember to REMOVE THEM before putting your package into production

  • Improving Click and Drag with C++

    - by Josh
    I'm currently using SFML 2.0 to develop a game in C++. I have a game sprite class that has a click and drag method. The method works, but there is a slight problem. If the mouse moves too fast, the object the user selected can't keep up and is left behind in the spot where the mouse left its bounds. I will share the class definition and the given function implementation. Definition: class codePeg { protected: FloatRect bounds; CircleShape circle; int xPos, yPos, xDiff, yDiff, once; int xBase, yBase; Vector2i mousePos; Vector2f circlePos; public: void init(RenderWindow& Window); void draw(RenderWindow& Window); void drag(RenderWindow& Window); void setPegPosition(int x, int y); void setPegColor(Color pegColor); void mouseOver(RenderWindow& Window); friend int isPegSelected(void); }; Implementation of the "drag" function: void codePeg::drag(RenderWindow& Window) { mousePos = Mouse::getPosition(Window); circlePos = circle.getPosition(); if(Mouse::isButtonPressed(Mouse::Left)) { if(mousePos.x > xPos && mousePos.y > yPos && mousePos.x - bounds.width < xPos && mousePos.y - bounds.height < yPos) { if(once) { xDiff = mousePos.x - circlePos.x; yDiff = mousePos.y - circlePos.y; once = 0; } xPos = mousePos.x - xDiff; yPos = mousePos.y - yDiff; circle.setPosition(xPos, yPos); } } else { once = 1; xPos = xBase; yPos = yBase; xDiff = 0; yDiff = 0; circle.setPosition(xBase, yBase); } Window.draw(circle); } Like I said, the function works, but to me, the code is very ugly and I think it could be improved and could be more efficient. The only thing I can think of as to why the object cannot keep up with the mouse is that there are too many function calls and/or checks. The user does not really have to mouse the mouse "fast" for it to happen, I would say at an average pace the object is left behind. How can I improve the code so that the object remains with the mouse when it is selected? Any help improving this code or giving advice is greatly appreciated.

  • RPi and Java Embedded GPIO: Big Data and Java Technology

    - by hinkmond
    Java Embedded and Big Data go hand-in-hand, especially as demonstrated by prototyping on a Raspberry Pi to show how well the Java Embedded platform can perform on a small embedded device which then becomes the proof-of-concept for industrial controllers, medical equipment, networking gear or any type of sensor-connected device generating large amounts of data. The key is a fast and reliable way to access that data using Java technology. In the previous blog posts you've seen the integration of a static electricity sensor and the Raspberry Pi through the GPIO port, then accessing that data through Java Embedded code. It's important to point out how this works and why it works well with Java code. First, the version of Linux (Debian Wheezy/Raspian) that is found on the RPi has a very convenient way to access the GPIO ports through the use of Linux OS managed file handles. This is key in avoiding terrible and complex coding using register manipulation in C code, or having to program in a less elegant and clumsy procedural scripting language such as python. Instead, using Java Embedded, allows a fast way to access those GPIO ports through those same Linux file handles. Java already has a very easy to program way to access file handles with a high degree of performance that matches direct access of those file handles with the Linux OS. Using the Java API java.io.FileWriter lets us open the same file handles that the Linux OS has for accessing the GPIO ports. Then, by first resetting the ports using the unexport and export file handles, we can initialize them for easy use in a Java app. // Open file handles to GPIO port unexport and export controls FileWriter unexportFile = new FileWriter("/sys/class/gpio/unexport"); FileWriter exportFile = new FileWriter("/sys/class/gpio/export"); ... // Reset the port unexportFile.write(gpioChannel); unexportFile.flush(); // Set the port for use exportFile.write(gpioChannel); exportFile.flush(); Then, another set of file handles can be used by the Java app to control the direction of the GPIO port by writing either "in" or "out" to the direction file handle. // Open file handle to input/output direction control of port FileWriter directionFile = new FileWriter("/sys/class/gpio/gpio" + gpioChannel + "/direction"); // Set port for input directionFile.write("in"); // Or, use "out" for output directionFile.flush(); And, finally, a RandomAccessFile handle can be used with a high degree of performance on par with native C code (only milliseconds to read in data and write out data) with low overhead (unlike python) to manipulate the data going in and out on the GPIO port, while the object-oriented nature of Java programming allows for an easy way to construct complex analytic software around that data access functionality to the external world. RandomAccessFile[] raf = new RandomAccessFile[GpioChannels.length]; ... // Reset file seek pointer to read latest value of GPIO port raf[channum].seek(0); raf[channum].read(inBytes); inLine = new String(inBytes); It's Big Data from sensors and industrial/medical/networking equipment meeting complex analytical software on a small constraint device (like a Linux/ARM RPi) where Java Embedded allows you to shine as an Embedded Device Software Designer.

  • The Best Data Integration for Exadata Comes from Oracle

    - by maria costanzo
    Oracle Data Integrator and Oracle GoldenGate offer unique and optimized data integration solutions for Oracle Exadata. For example, customers that choose to feed their data warehouse or reporting database with near real-time throughout the day, can do so without decreasing  performance or availability of source and target systems. And if you ask why real-time, the short answer is: in today’s fast-paced, always-on world, business decisions need to use more relevant, timely data to be able to act fast and seize opportunities. A longer response to "why real-time" question can be found in a related blog post. If we look at the solution architecture, as shown on the diagram below,  Oracle Data Integrator and Oracle GoldenGate are both uniquely designed to take full advantage of the power of the database and to eliminate unnecessary middle-tier components. Oracle Data Integrator (ODI) is the best bulk data loading solution for Exadata. ODI is the only ETL platform that can leverage the full power of Exadata, integrate directly on the Exadata machine without any additional hardware, and by far provides the simplest setup and fastest overall performance on an Exadata system. We regularly see customers achieving a 5-10 times boost when they move their ETL to ODI on Exadata. For  some companies the performance gain is even much higher. For example a large insurance company did a proof of concept comparing ODI vs a traditional ETL tool (one of the market leaders) on Exadata. The same process that was taking 5hrs and 11 minutes to complete using the competing ETL product took 7 minutes and 20 seconds with ODI. Oracle Data Integrator was 42 times faster than the conventional ETL when running on Exadata.This shows that Oracle's own data integration offering helps you to gain the most out of your Exadata investment with a truly optimized solution. GoldenGate is the best solution for streaming data from heterogeneous sources into Exadata in real time. Oracle GoldenGate can also be used together with Data Integrator for hybrid use cases that also demand non-invasive capture, high-speed real time replication. Oracle GoldenGate enables real-time data feeds from heterogeneous sources non-invasively, and delivers to the staging area on the target Exadata system. ODI runs directly on Exadata to use the database engine power to perform in-database transformations. Enterprise Data Quality is integrated with Oracle Data integrator and enables ODI to load trusted data into the data warehouse tables. Only Oracle can offer all these technical benefits wrapped into a single intelligence data warehouse solution that runs on Exadata. Compared to traditional ETL with add-on CDC this solution offers: §  Non-invasive data capture from heterogeneous sources and avoids any performance impact on source §  No mid-tier; set based transformations use database power §  Mini-batches throughout the day –or- bulk processing nightly which means maximum availability for the DW §  Integrated solution with Enterprise Data Quality enables leveraging trusted data in the data warehouse In addition to Starwood Hotels and Resorts, Morrison Supermarkets, United Kingdom’s fourth-largest food retailer, has seen the power of this solution for their new BI platform and shared their story with us. Morrisons needed to analyze data across a large number of manufacturing, warehousing, retail, and financial applications with the goal to achieve single view into operations for improved customer service. The retailer deployed Oracle GoldenGate and Oracle Data Integrator to bring new data into Oracle Exadata in near real-time and replicate the data into reporting structures within the data warehouse—extending visibility into operations. Using Oracle's data integration offering for Exadata, Morrisons produced financial reports in seconds, rather than minutes, and improved staff productivity and agility. You can read more about Morrison’s success story here and hear from Starwood here. From an Irem Radzik article.
