  • Vacations on Rodrigues 2014

    And now something completely different compared to the usual technical or community related articles here on this blog. Yes, this time I'm writing some lines on my (and my family's) activities during our long weekend stay on Rodrigues. So, please bear with me, it's eventually a bit more personal... Grab a soda, some popcorn and a cosy place to continue to read. var googleAlbumLink = "https://plus.google.com/photos/117698191428446859536/albums/6047895311458281985"; //optional----------------------- var mySlideWidth = 580; var mySlideHeight = 340; var mySlideDelay = 7000; //delay in milliseconds Special promotions during school holidays Originally, our children started to ask more frequently about going on the plane again. Obviously, after their aunty from Germany was around during May, they were really eager to travel again. So, we decided that it might be a great opportunity to book some vacations during their school holidays. And just in time the local hotels and hotel groups started to advertise their special promotions for citizens and residents. After collecting multiple brochures over several days, we got attracted by various hotel packages on Rodrigues - most interestingly the expenses for the stay and flight ticket were less compared to other resorts here on the main island. As we have been to Rodrigues already back in 2008, we followed up on this idea and got in touch with a couple travel agencies. Well, I have to report that you should be really careful about the promotions from some of them. We had a very negative experience with Shamal Travel Agency in Quatre Bornes regarding their adverts and the actual price levels and age definition for children. Please, stay away from them if you are interested in transparent cost and services. Anyway, after some arrangements with two other close families we managed to confirm our stay at the Cotton Bay Hotel in Rodrigues. Given the fact that we already stayed there, and the hotel has been renovated recently, and it is under new management all looked very promising and relaxed for our vacation. Counting the days... As we already booked in July our children were counting down the days. And it got more interesting as soon as they were on school holidays finally. Well, the day arrived and waking them up at 2:30 hrs wasn't a problem after all. Quite the opposite it was fascinating for us parents to watch them waiting for the transport and later on during the airport transfer. Despite the early hours both didn't fall asleep and it was all so exciting. We are taking the plane! Well organised by the Cotton Bay Hotel Honestly, it was a breeze and a smooth ride during our stay at the hotel. From the airport transfer, the cleanliness of our bungalow, the organisation of our day trips, and the SPA - all very well and enjoyable. The children had great fun, and although it was a bit too windy to plunge into the pool they had a lot of fun with other activities on the beach and at the Kid's Club. Oh, and we had our private petting zoo with cows, sheep and goats just close to the terrace. Some of us went to check out the SPA facilities and I have to admit that the services regarding Hammam and Sauna are better than at some other hotels in Mauritius. I don't know after how many months or years I was once again enjoying a very hot sauna. Little draw-back but nothing to worry about... There is no cold water or at least ice cubes to cool down the body, but hey there was a nice breeze coming over the hills. Some day trips to mention Based on a friend's recommendation we walked to a "restaurant" called Chez Solange & Robert. Hahaha, restaurant is widely stretched in this case, as we enjoyed a great BBQ with fresh lobster, whole fish, and pieces of chicken breast in an open cottage. Just some wooden structure covered with dried palm leaves on the roof - island feeling pure! The other day we went to the Giant Tortoise & Cave Reserve Francois Leguat to observe the giant Aldabra turtles and to visit the Grande Caverne. The biggest limestone cave on the island. Compared to our last visit this was a novelty after checking out the Caverne Partate. The formations of stalactites and stalagmites are very impressive and imaginative. Our guide had lots of funny terms and despite the low light conditions the kids had a great time wandering around on the narrow wooden paths and stairs. And last but not least, we decided to check out the Tyrodrig zip lines... Everyone was allowed to join the trip through the air, and our little ones stayed close to our field guides. But finally went on their own on the very last traversal. Puuuh, it was astounishing to glide over the valley, and for sure something to repeat next time. Impressions of our vacation on Rodrigues 2014   Next stay has been discussed already Oh yes, Rodrigues baby! We are going to come again! Tentative dates have been discussed already and now it's up to us to earn enough our next holiday on that wonderful remote piece of paradise. Eventually, a little bit longer than this time. We'll see...

  • EU Digital Agenda scores 85/100

    - by trond-arne.undheim
    If the Digital Agenda was a bottle of wine and I were wine critic Robert Parker, I would say the Digital Agenda has "a great bouquet, many good elements, with astringent, dry and puckering mouth feel that will not please everyone, but still displaying some finesse. A somewhat controlled effort with no surprises and a few noticeable flaws in the delivery. Noticeably shorter aftertaste than advertised by the producers. Score: 85/100. Enjoy now". The EU Digital Agenda states that "standards are vital for interoperability" and has a whole chapter on interoperability and standards. With this strong emphasis, there is hope the EU's outdated standardization system finally is headed for reform. It has been 23 years since the legal framework of standardisation was completed by Council Decision 87/95/EEC8 in the Information and Communications Technology (ICT) sector. Standardization is market driven. For several decades the IT industry has been developing standards and specifications in global open standards development organisations (fora/consortia), many of which have transparency procedures and practices far superior to the European Standards Organizations. The Digital Agenda rightly states: "reflecting the rise and growing importance of ICT standards developed by certain global fora and consortia". Some fora/consortia, of course, are distorted, influenced by single vendors, have poor track record, and need constant vigilance, but they are the minority. Therefore, the recognition needs to be accompanied by eligibility criteria focused on openness. Will the EU reform its ICT standardization by the end of 2010? Possibly, and only if DG Enterprise takes on board that Information and Communications Technologies (ICTs) have driven half of the productivity growth in Europe over the past 15 years, a prominent fact in the EU's excellent Digital Competitiveness report 2010 published on Monday 17 May. It is ok to single out the ICT sector. It simply is the most important sector right now as it fuels growth in all other sectors. Let's not wait for the entire standardization package which may take another few years. Europe does not have time. The Digital Agenda is an umbrella strategy with deliveries from a host of actors across the Commission. For instance, the EU promises to issue "guidance on transparent ex-ante disclosure rules for essential intellectual property rights and licensing terms and conditions in the context of standard setting", by 2011 in the Horisontal Guidelines now out for public consultation by DG COMP and to some extent by DG ENTR's standardization policy reform. This is important. The EU will issue procurement guidance as interoperability frameworks are put into practice. This is a joint responsibility of several DGs, and is likely to suffer coordination problems, controversy and delays. We have seen plenty of the latter already and I have commented on the Commission's own interoperability elsewhere, with mixed luck. :( Yesterday, I watched the cartoonesque Korean western film The Good, the Bad and the Weird. In the movie (and I meant in the movie only), a bandit, a thief, and a bounty hunter, all excellent at whatever they do, fight for a treasure map. Whether that is a good analogy for the situation within the Commission, others are better judges of than I. However, as a movie fanatic, I still await the final shoot-out, and, as in the film, the only certainty is that "life is about chasing and being chased". The missed opportunity (in this case not following up the push from Member States to better define open standards based interoperability) is a casualty of the chaos ensued in the European Wild West (and I mean that in the most endearing sense, and my excuses beforehand to actors who possibly justifiably cannot bear being compared to fictional movie characters). Instead of exposing the ongoing fight, the EU opted for the legalistic use of the term "standards" throughout the document. This is a term that--to the EU-- excludes most standards used by the IT industry world wide. So, while it, for a moment, meant "weapon down", it will not lead to lasting peace. The Digital Agenda calls for the Member States to "Implement commitments on interoperability and standards in the Malmö and Granada Declarations by 2013". This is a far cry from the actual Ministerial Declarations which called upon the Commission to help them with this implementation by recognizing and further defining open standards based interoperability. Unless there is more forthcoming from the Commission, the market's judgement will be: you simply fall short. Generally, I think the EU focus now should be "from policy to practice" and the Digital Agenda does indeed stop short of tackling some highly practical issues. There is need for progress beyond the Digital Agenda. Here are some suggestions that would help Europe re-take global leadership on openness, public sector reform, and economic growth: A strong European software strategy centred around open standards based interoperability by 2011. An ambitious new eCommission strategy for 2011-15 focused on migration to open standards by 2015. Aligning the IT portfolio across the Commission into one Digital Agenda DG by 2012. Focusing all best practice exchange in eGovernment on one social networking site, epractice.eu (full disclosure: I had a role in getting that site up and running) Prioritizing public sector needs in global standardization over European standardization by 2014.

  • Why do my 512x512 bitmaps look jaggy on Android OpenGL?

    - by Milo Mordaunt
    This is sort of driving me nuts, I've googled and googled and tried everything I can think of, but my sprites still look super blurry and super jaggy. Example: Here: https://docs.google.com/open?id=0Bx9Gbwnv9Hd2TmpiZkFycUNmRTA If you click through to the actual full size image you should see what I mean, it's like it's taking and average of every 5*5 pixels or something, the background looks really blurry and blocky, but the ball is the worst. The clouds look all right for some reason, probably because they're mostly transparent. I know the pngs aren't top notch themselves but hey, I'm no artist! I would imagine it's a problem with either: a. How the pngs are made example sprite (512x512): https://docs.google.com/open?id=0Bx9Gbwnv9Hd2a2RRQlJiQTFJUEE b. How my Matrices work This is the relevant parts of the renderer: public void onDrawFrame(GL10 unused) { if(world != null) { dt = System.currentTimeMillis() - endTime; world.update( (float) dt); // Redraw background color GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT); Matrix.setIdentityM(mvMatrix, 0); Matrix.translateM(mvMatrix, 0, 0f, 0f, 0f); world.draw(mvMatrix, mProjMatrix); endTime = System.currentTimeMillis(); } else { Log.d(TAG, "There is no world...."); } } public void onSurfaceChanged(GL10 unused, int width, int height) { GLES20.glViewport(0, 0, width, height); Matrix.orthoM(mProjMatrix, 0, 0, width /2, 0, height /2, -1.f, 1.f); } And this is what each Quad does when draw is called: public void draw(float[] mvMatrix, float[] pMatrix) { Matrix.setIdentityM(mMatrix, 0); Matrix.setIdentityM(mvMatrix, 0); Matrix.translateM(mMatrix, 0, xPos, yPos, 0.f); Matrix.multiplyMM(mvMatrix, 0, mvMatrix, 0, mMatrix, 0); Matrix.scaleM(mvMatrix, 0, scale, scale, 0f); Matrix.rotateM(mvMatrix, 0, angle, 0f, 0f, -1f); GLES20.glUseProgram(mProgram); posAttr = GLES20.glGetAttribLocation(mProgram, "vPosition"); texAttr = GLES20.glGetAttribLocation(mProgram, "aTexCo"); uSampler = GLES20.glGetUniformLocation(mProgram, "uSampler"); int alphaHandle = GLES20.glGetUniformLocation(mProgram, "alpha"); GLES20.glVertexAttribPointer(posAttr, COORDS_PER_VERTEX, GLES20.GL_FLOAT, false, 0, vertexBuffer); GLES20.glVertexAttribPointer(texAttr, 2, GLES20.GL_FLOAT, false, 0, texCoBuffer); GLES20.glEnableVertexAttribArray(posAttr); GLES20.glEnableVertexAttribArray(texAttr); GLES20.glActiveTexture(GLES20.GL_TEXTURE0); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, texture); GLES20.glUniform1i(uSampler, 0); GLES20.glUniform1f(alphaHandle, alpha); mMVMatrixHandle = GLES20.glGetUniformLocation(mProgram, "uMVMatrix"); mPMatrixHandle = GLES20.glGetUniformLocation(mProgram, "uPMatrix"); GLES20.glUniformMatrix4fv(mMVMatrixHandle, 1, false, mvMatrix, 0); GLES20.glUniformMatrix4fv(mPMatrixHandle, 1, false, pMatrix, 0); GLES20.glDrawElements(GLES20.GL_TRIANGLE_STRIP, 4, GLES20.GL_UNSIGNED_SHORT, indicesBuffer); GLES20.glDisableVertexAttribArray(posAttr); GLES20.glDisableVertexAttribArray(texAttr); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, 0); } c. How my texture loading/blending/shaders setup works Here is the renderer setup: public void onSurfaceCreated(GL10 unused, EGLConfig config) { // Set the background frame color GLES20.glClearColor(0.0f, 0.0f, 0.0f, 1.0f); GLES20.glDisable(GLES20.GL_DEPTH_TEST); GLES20.glDepthMask(false); GLES20.glBlendFunc(GLES20.GL_ONE, GLES20.GL_ONE_MINUS_SRC_ALPHA); GLES20.glEnable(GLES20.GL_BLEND); GLES20.glEnable(GLES20.GL_DITHER); } Here is the vertex shader: attribute vec4 vPosition; attribute vec2 aTexCo; varying vec2 vTexCo; uniform mat4 uMVMatrix; uniform mat4 uPMatrix; void main() { gl_Position = uPMatrix * uMVMatrix * vPosition; vTexCo = aTexCo; } And here's the fragment shader: precision mediump float; uniform sampler2D uSampler; uniform vec4 vColor; varying vec2 vTexCo; varying float alpha; void main() { vec4 color = texture2D(uSampler, vec2(vTexCo)); gl_FragColor = color; if(gl_FragColor.a == 0.0) { "discard; } } This is how textures are loaded: private int loadTexture(int rescource) { int[] texture = new int[1]; BitmapFactory.Options opts = new BitmapFactory.Options(); opts.inScaled = false; Bitmap temp = BitmapFactory.decodeResource(context.getResources(), rescource, opts); GLES20.glGenTextures(1, texture, 0); GLES20.glActiveTexture(GLES20.GL_TEXTURE0); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, texture[0]); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MAG_FILTER, GLES20.GL_LINEAR); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MIN_FILTER, GLES20.GL_LINEAR); GLUtils.texImage2D(GLES20.GL_TEXTURE_2D, 0, temp, 0); GLES20.glGenerateMipmap(GLES20.GL_TEXTURE_2D); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, 0); temp.recycle(); return texture[0]; } I'm sure I'm doing about 20,000 things wrong, so I'm really sorry if the problem is blindingly obvious... The test device is a Galaxy Note, running a JellyBean custom ROM, if that matters at all. So the screen resolution is 1280x800, which means... The background is 1024x1024, so yeah it might be a little blurry, but shouldn't be made of lego. Thank you so much, any answer at all would be appreciated.

  • How to Customize Fonts and Colors for Gnome Panels in Ubuntu Linux

    - by The Geek
    Earlier this week we showed you how to make the Gnome Panels totally transparent, but you really need some customized fonts and colors to make the effect work better. Here’s how to do it. This article is the first part of a multi-part series on how to customize the Ubuntu desktop, written by How-To Geek reader and ubergeek, Omar Hafiz. Changing the Gnome Colors the Easy Way You’ll first need to install Gnome Color Chooser which is available in the default repositories (the package name is gnome-color-chooser). Then go to System > Preferences > Gnome Color Chooser to launch the program. When you see all these tabs you immediately know that Gnome Color Chooser does not only change the font color of the panel, but also the color of the fonts all over Ubuntu, desktop icons, and many other things as well. Now switch to the panel tab, here you can control every thing about your panels. You can change font, font color, background and background color of the panels and start menus. Tick the “Normal” option and choose the color you want for the panel font. If you want you can change the hover color of the buttons on the panel by too. A little below the color option is the font options, this includes the font, font size, and the X and Y positioning of the font. The first two options are pretty straight forward, they change the typeface and the size. The X-Padding and Y-Padding may confuse you but they are interesting, they may give a nice look for your panels by increasing the space between items on your panel like this: X-Padding:   Y-Padding:   The bottom half of the window controls the look of your start menus which is the Applications, Places, and Systems menus. You can customize them just the way you did with the panel.   Alright, this was the easy way to change the font of your panels. Changing the Gnome Theme Colors the Command-Line Way The other hard (not so hard really) way will be changing the configuration files that tell your panel how it should look like. In your Home Folder, press Ctrl+H to show the hidden files, now find the file “.gtkrc-2.0”, open it and insert this line in it. If there are any other lines in the file leave them intact. include “/home/<username>/.gnome2/panel-fontrc” Don’t forget to replace the <user_name> with you user account name. When done close and save the file. Now navigate the folder “.gnome2” from your Home Folder and create a new file and name it “panel-fontrc”. Open the file you just created with a text editor and paste the following in it: style “my_color”{fg[NORMAL] = “#FF0000”}widget “*PanelWidget*” style “my_color”widget “*PanelApplet*” style “my_color” This text will make the font red. If you want other colors you’ll need to replace the Hex value/HTML Notation (in this case #FF0000) with the value of the color you want. To get the hex value you can use GIMP, Gcolor2 witch is available in the default repositories or you can right-click on your panel > Properties > Background tab then click to choose the color you want and copy the Hex value. Don’t change any other thing in the text. When done, save and close. Now press Alt+F2 and enter “killall gnome-panel” to force it to restart or you can log out and login again. Most of you will prefer the first way of changing the font and color for it’s ease of applying and because it gives you much more options but, some may not have the ability/will to download and install a new program on their machine or have reasons of their own for not to using it, that’s why we provided the two way.

  • JavaOne 2012 Sunday Strategy Keynote

    - by Janice J. Heiss
    At the Sunday Strategy Keynote, held at the Masonic Auditorium, Hasan Rizvi, EVP, Middleware and Java Development, stated that the theme for this year's JavaOne is: “Make the future Java”-- meaning that Java continues in its role as the most popular, complete, productive, secure, and innovative development platform. But it also means, he qualified, the process by which we make the future Java -- an open, transparent, collaborative, and community-driven evolution. "Many of you have bet your businesses and your careers on Java, and we have bet our business on Java," he said.Rizvi detailed the three factors they consider critical to the success of Java--technology innovation, community participation, and Oracle's leadership/stewardship. He offered a scorecard in these three realms over the past year--with OS X and Linux ARM support on Java SE, open sourcing of JavaFX by the end of the year, the release of Java Embedded Suite 7.0 middleware platform, and multiple releases on the Java EE side. The JCP process continues, with new JSR activity, and JUGs show a 25% increase in participation since last year. Oracle, meanwhile, continues its commitment to both technology and community development/outreach--with four regional JavaOne conferences last year in various part of the world, as well as the release of Java Magazine, with over 120,000 current subscribers. Georges Saab, VP Development, Java SE, next reviewed features of Java SE 7--the first major revision to the platform under Oracle's stewardship, which has included near-monthly update releases offering hundreds of fixes, performance enhancements, and new features. Saab indicated that developers, ISVs, and hosting providers have all been rapid adopters of the platform. He also noted that Oracle's entire Fusion middleware stack is supported on SE 7. The supported platforms for SE 7 has also increased--from Windows, Linux, and Solaris, to OS X, Linux ARM, and the emerging ARM micro-server market. "In the last year, we've added as many new platforms for Java, as were added in the previous decade," said Saab.Saab also explored the upcoming JDK 8 release--including Project Lambda, Project Nashorn (a modern implementation of JavaScript running on the JVM), and others. He noted that Nashorn functionality had already been used internally in NetBeans 7.3, and announced that they were planning to contribute the implementation to OpenJDK. Nandini Ramani, VP Development, Java Client, ME and Card, discussed the latest news pertaining to JavaFX 2.0--releases on Windows, OS X, and Linux, release of the FX Scene Builder tool, the JavaFX WebView component in NetBeans 7.3, and an OpenJFX project in OpenJDK. Nandini announced, as of Sunday, the availability for download of JavaFX on Linux ARM (developer preview), as well as Scene Builder on Linux. She noted that for next year's JDK 8 release, JavaFX will offer 3D, as well as third-party component integration. Avinder Brar, Senior Software Engineer, Navis, and Dierk König, Canoo Fellow, next took the stage and demonstrated all that JavaFX offers, with a feature-rich, animation-rich, real-time cargo management application that employs Canoo's just open-sourced Dolphin technology.Saab also explored Java SE 9 and beyond--Jigsaw modularity, Penrose Project for interoperability with OSGi, improved multi-tenancy for Java in the cloud, and Project Sumatra. Phil Rogers, HSA Foundation President and AMD Corporate Fellow, explored heterogeneous computing platforms that combine the CPU and the parallel processor of the GPU into a single piece of silicon and shared memory—a hardware technology driven by such advanced functionalities as HD video, face recognition, and cloud workloads. Project Sumatra is an OpenJDK project targeted at bringing Java to such heterogeneous platforms--with hardware and software experts working together to modify the JVM for these advanced applications and platforms.Ramani next discussed the latest with Java in the embedded space--"the Internet of things" and M2M--declaring this to be "the next IT revolution," with Java as the ideal technology for the ecosystem. Last week, Oracle released Java ME Embedded 3.2 (for micro-contollers and low-power devices), and Java Embedded Suite 7.0 (a middleware stack based on Java SE 7). Axel Hansmann, VP Strategy and Marketing, Cinterion, explored his company's use of Java in M2M, and their new release of EHS5, the world's smallest 3G-capable M2M module, running Java ME Embedded. Hansmaan explained that Java offers them the ability to create a "simple to use, scalable, coherent, end-to-end layer" for such diverse edge devices.Marc Brule, Chief Financial Office, Royal Canadian Mint, also explored the fascinating use-case of JavaCard in his country's MintChip e-cash technology--deployable on smartphones, USB device, computer, tablet, or cloud. In parting, Ramani encouraged developers to download the latest releases of Java Embedded, and try them out.Cameron Purdy, VP, Fusion Middleware Development and Java EE, summarized the latest developments and announcements in the Enterprise space--greater developer productivity in Java EE6 (with more on the way in EE 7), portability between platforms, vendors, and even cloud-to-cloud portability. The earliest version of the Java EE 7 SDK is now available for download--in GlassFish 4--with WebSocket support, better JSON support, and more. The final release is scheduled for April of 2013. Nicole Otto, Senior Director, Consumer Digital Technology, Nike, explored her company's Java technology driven enterprise ecosystem for all things sports, including the NikeFuel accelerometer wrist band. Looking beyond Java EE 7, Purdy mentioned NoSQL database functionality for EE 8, the concurrency utilities (possibly in EE 7), some of the Avatar projects in EE 7, some in EE 8, multi-tenancy for the cloud, supporting SaaS applications, and more.Rizvi ended by introducing Dr. Robert Ballard, oceanographer and National Geographic Explorer in Residence--part of Oracle's philanthropic relationship with the National Geographic Society to fund K-12 education around ocean science and conservation. Ballard is best known for having discovered the wreckage of the Titanic. He offered a fascinating video and overview of the cutting edge technology used in such deep-sea explorations, noting that in his early days, high-bandwidth exploration meant that you’d go down in a submarine and "stick your face up against the window." Now, it's a remotely operated, technology telepresence--"I think of my Hercules vehicle as my equivalent of a Na'vi. When I go beneath the sea, I actually send my spirit." Using high bandwidth satellite links, such amazing explorations can now occur via smartphone, laptop, or whatever platform. Ballard’s team regularly offers live feeds and programming out to schools and the world, spanning 188 countries--with embedding educators as part of the expeditions. It's technology at its finest, inspiring the next-generation of scientists and explorers!

  • Gamification at OOW

    - by erikanollwebb
    Last week was Oracle OpenWorld, and for those of you not in tech or downtown San Francisco, that might not mean a whole lot.  However, if you are familiar with it, Oracle OpenWorld is our premier customer event.  This year, more than 50,000 people attended.  It's not a good week to visit San Francisco on vacation because Oracle customers take over all the hotels in town!  It was crazy, but a lot of fun and it's a great opportunity for the Apps UX group to do customer research with a range of customers.  This year, more than 100+ customers and partners took the time to team up with our UX experts and provide feedback on new designs and ideas. Over three days,  UX teams conducted 8  one-on-one user feedback sessions, 4 focus groups and 7 surveys. In addition, we conducted a voice capture activity and were able to collect close to 70 speech samples at the lab and DEMOgrounds. This was a great opportunity for us to do some testing on some specific gamification concepts with a set of business analysts.  We pulled in 8 folks for a focus group on gamification concepts and whether they thought those would work for their teams. To get ready for this, my designer extraordinaire, Andrea Cantú, flew into town and we spent almost a week locked in a room together brainstorming design ideas.  We killed a few trees trying to get all of our concepts and other examples together in the process, but in the end, we put together a whole series of examples of how you might gamify an Oracle app (in this case, CRM).  Andrea is a genius for this kind of thing and the comps she created looked great.  Here's a picture of her hard at work!  We also had the good fortune to have my boss, Laurie Pattison and my usability contractor, Shobana Subramanian there to note take and observe as well.  Here's a few shots of us, hard at work preparing for the day (or checking out something on Laurie's iPhone...) To start things off, we gave an overview of gamification and I talked about what it's used for.  Then we gave the participants a scenario about our sales person and what we were trying to get her to do. It was a great opportunity to highlight what our business goals might be and why we might want to add game mechanics.  It was also a good way to get them thinking about how that might work for them in their environments and workplaces. There were some surprises for the day.  We asked how many of them were already familiar with the concept of gamification--only two people had heard of it and only one was using game mechanics in his work.  That's in contrast to a survey we just ran internally with folks in a dev org where almost 50% of about 450 respondents had heard of gamification.  As we discussed the ways game mechanics could be used, it became clear that many of the folks had seen some game mechanics in action but didn't know that's what they were.  We also noticed that the folks in this group felt that if they were trying to sell the concept in their orgs, they wouldn't call it gamification.  That's not a huge surprise to me--they said what we've heard in the past, that gamification does not seem like a serious term for enterprise software.  They said they'd sell it with the goals--as a means to increase behaviors by rewarding users for activities.  It's a funny problem.  The word puts some folks off, but at the same time, I haven't seen another one word description that quite captures the range of things that "gamification" can cover.  My guess is that the more mainstream the term becomes, the more desensitized we'll become to the idea the it's trivializing enterprise software in some way.  Still, it was interesting to note that this group still felt that they would not take this concept to their bosses or teams and call it "gamification".  They focused on the goals, and how we could incentivize desired behaviors with game mechanics.  As I have already stated in other posts, I feel like my org is more receptive to discussing how this is just a more transparent type of usability and user experience methods than talking about gamification.  That's the argument they said they would use. All in all, it was a good session.  I love getting to talk to customers, present ideas and concepts, and get their feedback and input.  It's the type of thing that really helps drive our designs and keeps us grounded in what our customers need/want.  We're already planning where to get more feedback opportunities in the coming months.

Siemens offers its customers products and solutions for the entire range of patient care from a single source – from prevention and early detection to diagnosis, and on to treatment and aftercare. By optimizing clinical workflows for the most common diseases, Siemens also makes healthcare faster, better and more cost-effective. To ensure greater transparency, increased efficiency, higher user acceptance, and additional services, Siemens AG, Sector Healthcare, replaced several existing legacy portal solutions that could not meet the company’s future needs with Oracle WebCenter Portal. Various existing portal solutions that cannot meet future demands will be successively replaced by the new central service portal, which will also allow for the efficient and intuitive implementation of new service concepts.  With Oracle, doctors and hospitals using Siemens medical solutions now have access to a central information portal that provides important information and services at just the push of a button.  Customer Name – Siemens AG, Sector Healthcare Customer URL – www.siemens.com Customer Headquarters – Erlangen, Germany Industry – Industrial Manufacturing Employees – 360,000  Challenges – Replace disparate medical service portals to meet future demands and eliminate an  unnecessarily high level of administrative work caused by heterogeneous installations Ensure portals meet current user demands to improve user-acceptance rates and increase number of total users Enable changes and expansion through standard functionality to eliminate the need for reliance on IT and reduce administrative efforts and associated high costs Ensure efficient and intuitive implementation of new service concepts for all devices and systems Ensure hospitals and clinics to transparently monitor and measure services rendered for the various medical devices and systems  Increase electronic interaction and expand services to achieve a higher level of customer loyalty Solution –  Deployed Oracle WebCenter Portal to ensure greater transparency, and as a result, a higher level of customer loyalty  Provided a centralized platform for doctors and hospitals using Siemens’ medical technology solutions that provides important information and services at the push of a button Reduced significantly the administrative workload by centralizing the solution in the new customer service portal Secured positive feedback from customers involved in the pilot program developed by design experts from Oracle partner Sapient. The interfaces were created with customer needs in mind. The first survey taken shortly after implementation came back with 2.4 points on a scale of 0-3 in the category “customer service portal intuitiveness level” Met all requirements including alignment with the Siemens Style Guide without extensive programming Implemented additional services via the portal such as benchmarking options to ensure the optimal use of the Customer Device Park Provided option for documentation of all services rendered in conjunction with the medical technology systems to ensure that the value of the services are transparent for the decision makers in the hospitals  Saved and stored all machine data from approximately 100,000 remote systems in the central service and information platform Provided the option to register errors online and follow the call status in real-time on the portal Made  available at the push of a button all information on the medical technology devices used in hospitals or clinics—from security checks and maintenance activities to current device statuses Provided PDF format Service Performance Reports that summarize information from periods of time ranging from previous weeks up to one year, meeting medical product law requirements  Why Oracle – Siemens AG favored Oracle for many reasons, however, the company ultimately decided to go with Oracle due to the enormous range of functionality the solutions offered for the healthcare sector.“We are not programmers; we are service providers in the medical technology segment and focus on the contents of the portal. All the functionality necessary for internet-based customer interaction is already standard in Oracle WebCenter Portal, which is a huge plus for us. Having Oracle as our technology partner ensures that the product will continually evolve, providing a strong technology platform for our customer service portal well into the future,” said Joerg Modlmayr project manager, Healthcare Customer Service Portal, Siemens AG. Partner Involvement – Siemens AG selected Oracle Partner Sapient because the company offered a service portfolio that perfectly met Siemens’ requirements and had a wealth of experience implementing Oracle WebCenter Portal. Additionally, Sapient had designers with a very high level of expertise in usability—an aspect that Siemens considered to be of vast importance for the project.  “The Sapient team completely met all our expectations. Our tightly timed project was completed on schedule, and the positive feedback from our users proves that we set the right measures in terms of usability—all thanks to the folks at Sapient,” Modlmayr said.  Partner Name – Sapient GmbH Deutschland Partner URL – www.sapient.com

  • Breaking 1NF to model subset constraints. Does this sound sane?

    - by Chris Travers
    My first question here. Appologize if it is in the wrong forum but this seems pretty conceptual. I am looking at doing something that goes against conventional wisdom and want to get some feedback as to whether this is totally insane or will result in problems, so critique away! I am on PostgreSQL 9.1 but may be moving to 9.2 for this part of this project. To re-iterate: Does it seem sane to break 1NF in this way? I am not looking for debugging code so much as where people see problems that this might lead. The Problem In double entry accounting, financial transactions are journal entries with an arbitrary number of lines. Each line has either a left value (debit) or a right value (credit) which can be modelled as a single value with negatives as debits and positives as credits or vice versa. The sum of all debits and credits must equal zero (so if we go with a single amount field, sum(amount) must equal zero for each financial journal entry). SQL-based databases, pretty much required for this sort of work, have no way to express this sort of constraint natively and so any approach to enforcing it in the database seems rather complex. The Write Model The journal entries are append only. There is a possibility we will add a delete model but it will be subject to a different set of restrictions and so is not applicable here. If and when we allow deletes, we will probably do them using a simple ON DELETE CASCADE designation on the foreign key, and require that deletes go through a dedicated stored procedure which can enforce the other constraints. So inserts and selects have to be accommodated but updates and deletes do not for this task. My Proposed Solution My proposed solution is to break first normal form and model constraints on arrays of tuples, with a trigger that breaks the rows out into another table. CREATE TABLE journal_line ( entry_id bigserial primary key, account_id int not null references account(id), journal_entry_id bigint not null, -- adding references later amount numeric not null ); I would then add "table methods" to extract debits and credits for reporting purposes: CREATE OR REPLACE FUNCTION debits(journal_line) RETURNS numeric LANGUAGE sql IMMUTABLE AS $$ SELECT CASE WHEN $1.amount < 0 THEN $1.amount * -1 ELSE NULL END; $$; CREATE OR REPLACE FUNCTION credits(journal_line) RETURNS numeric LANGUAGE sql IMMUTABLE AS $$ SELECT CASE WHEN $1.amount > 0 THEN $1.amount ELSE NULL END; $$; Then the journal entry table (simplified for this example): CREATE TABLE journal_entry ( entry_id bigserial primary key, -- no natural keys :-( journal_id int not null references journal(id), date_posted date not null, reference text not null, description text not null, journal_lines journal_line[] not null ); Then a table method and and check constraints: CREATE OR REPLACE FUNCTION running_total(journal_entry) returns numeric language sql immutable as $$ SELECT sum(amount) FROM unnest($1.journal_lines); $$; ALTER TABLE journal_entry ADD CONSTRAINT CHECK (((journal_entry.running_total) = 0)); ALTER TABLE journal_line ADD FOREIGN KEY journal_entry_id REFERENCES journal_entry(entry_id); And finally we'd have a breakout trigger: CREATE OR REPLACE FUNCTION je_breakout() RETURNS TRIGGER LANGUAGE PLPGSQL AS $$ BEGIN IF TG_OP = 'INSERT' THEN INSERT INTO journal_line (journal_entry_id, account_id, amount) SELECT NEW.id, account_id, amount FROM unnest(NEW.journal_lines); RETURN NEW; ELSE RAISE EXCEPTION 'Operation Not Allowed'; END IF; END; $$; And finally CREATE TRIGGER AFTER INSERT OR UPDATE OR DELETE ON journal_entry FOR EACH ROW EXECUTE_PROCEDURE je_breaout(); Of course the example above is simplified. There will be a status table that will track approval status allowing for separation of duties, etc. However the goal here is to prevent unbalanced transactions. Any feedback? Does this sound entirely insane? Standard Solutions? In getting to this point I have to say I have looked at four different current ERP solutions to this problems: Represent every line item as a debit and a credit against different accounts. Use of foreign keys against the line item table to enforce an eventual running total of 0 Use of constraint triggers in PostgreSQL Forcing all validation here solely through the app logic. My concerns are that #1 is pretty limiting and very hard to audit internally. It's not programmer transparent and so it strikes me as being difficult to work with in the future. The second strikes me as being very complex and required a series of contraints and foreign keys against self to make work, and therefore it strikes me as complex, hard to sort out at least in my mind, and thus hard to work with. The fourth could be done as we force all access through stored procedures anyway and this is the most common solution (have the app total things up and throw an error otherwise). However, I think proof that a constraint is followed is superior to test cases, and so the question becomes whether this in fact generates insert anomilies rather than solving them. If this is a solved problem it isn't the case that everyone agrees on the solution....

  • Performance triage

    - by Dave
    Folks often ask me how to approach a suspected performance issue. My personal strategy is informed by the fact that I work on concurrency issues. (When you have a hammer everything looks like a nail, but I'll try to keep this general). A good starting point is to ask yourself if the observed performance matches your expectations. Expectations might be derived from known system performance limits, prototypes, and other software or environments that are comparable to your particular system-under-test. Some simple comparisons and microbenchmarks can be useful at this stage. It's also useful to write some very simple programs to validate some of the reported or expected system limits. Can that disk controller really tolerate and sustain 500 reads per second? To reduce the number of confounding factors it's better to try to answer that question with a very simple targeted program. And finally, nothing beats having familiarity with the technologies that underlying your particular layer. On the topic of confounding factors, as our technology stacks become deeper and less transparent, we often find our own technology working against us in some unexpected way to choke performance rather than simply running into some fundamental system limit. A good example is the warm-up time needed by just-in-time compilers in Java Virtual Machines. I won't delve too far into that particular hole except to say that it's rare to find good benchmarks and methodology for java code. Another example is power management on x86. Power management is great, but it can take a while for the CPUs to throttle up from low(er) frequencies to full throttle. And while I love "turbo" mode, it makes benchmarking applications with multiple threads a chore as you have to remember to turn it off and then back on otherwise short single-threaded runs may look abnormally fast compared to runs with higher thread counts. In general for performance characterization I disable turbo mode and fix the power governor at "performance" state. Another source of complexity is the scheduler, which I've discussed in prior blog entries. Lets say I have a running application and I want to better understand its behavior and performance. We'll presume it's warmed up, is under load, and is an execution mode representative of what we think the norm would be. It should be in steady-state, if a steady-state mode even exists. On Solaris the very first thing I'll do is take a set of "pstack" samples. Pstack briefly stops the process and walks each of the stacks, reporting symbolic information (if available) for each frame. For Java, pstack has been augmented to understand java frames, and even report inlining. A few pstack samples can provide powerful insight into what's actually going on inside the program. You'll be able to see calling patterns, which threads are blocked on what system calls or synchronization constructs, memory allocation, etc. If your code is CPU-bound then you'll get a good sense where the cycles are being spent. (I should caution that normal C/C++ inlining can diffuse an otherwise "hot" method into other methods. This is a rare instance where pstack sampling might not immediately point to the key problem). At this point you'll need to reconcile what you're seeing with pstack and your mental model of what you think the program should be doing. They're often rather different. And generally if there's a key performance issue, you'll spot it with a moderate number of samples. I'll also use OS-level observability tools to lock for the existence of bottlenecks where threads contend for locks; other situations where threads are blocked; and the distribution of threads over the system. On Solaris some good tools are mpstat and too a lesser degree, vmstat. Try running "mpstat -a 5" in one window while the application program runs concurrently. One key measure is the voluntary context switch rate "vctx" or "csw" which reflects threads descheduling themselves. It's also good to look at the user; system; and idle CPU percentages. This can give a broad but useful understanding if your threads are mostly parked or mostly running. For instance if your program makes heavy use of malloc/free, then it might be the case you're contending on the central malloc lock in the default allocator. In that case you'd see malloc calling lock in the stack traces, observe a high csw/vctx rate as threads block for the malloc lock, and your "usr" time would be less than expected. Solaris dtrace is a wonderful and invaluable performance tool as well, but in a sense you have to frame and articulate a meaningful and specific question to get a useful answer, so I tend not to use it for first-order screening of problems. It's also most effective for OS and software-level performance issues as opposed to HW-level issues. For that reason I recommend mpstat & pstack as my the 1st step in performance triage. If some other OS-level issue is evident then it's good to switch to dtrace to drill more deeply into the problem. Only after I've ruled out OS-level issues do I switch to using hardware performance counters to look for architectural impediments.

  • Reading the tea leaves from Windows Azure support

    - by jamiet
    A few idle thoughts… Three months ago I had an issue regarding Windows Azure where I was unable to login to the management portal. At the time I contacted Azure support, the issue was soon resolved and I thought no more about it. Until today that is when I received an email from Azure support providing a detailed analysis of the root cause, the fix and moreover precise details about when and where things occurred. The email itself is interesting and I have included the entirety of it below. A few things were interesting to me: The level of detail and the diligence in investigating and reporting the issue I found really rather impressive. They even outline the number of users that were affected (127 in case you can’t be bothered reading). Compare this to the quite pathetic support that another division within Microsoft, Skype, provided to Greg Low recently: Skype support and dead parrot sketches   This line: “Windows Azure performed a planned change from using the Microsoft account service (formerly Windows Live ID) to the Azure Active Directory (AAD) as its primary authentication mechanism on August 24th. This change was made to enable future innovation in the area of authentication – particularly for organizationally owned identities, identity federation, stronger authentication methods and compliance certification. ” I also found to be particularly interesting. I have long thought that one of the reasons Microsoft has proved to be such a money-making machine in the enterprise is because they provide the infrastructure and then upsell on top of that – and nothing is more infrastructural than Active Directory. It has struck me of late that they are trying to make the same play of late in the cloud by tying all their services into Azure Active Directory and here we see a clear indication of that by making AAD the authentication mechanism for anyone using Windows Azure. I get the feeling that we’re going to hear much much more about AAD in the future; isn’t it about time we could log on to SQL Azure Windows Azure SQL Database without resorting to SQL authentication, for example? And why do Microsoft have two identity providers – Microsoft Account (aka Windows Live ID) and AAD – isn’t it about time those things were combined? As I said, just some idle thoughts. Below is the transcript of the email if you are interested. @Jamiet  This is regarding the support request <redacted> where in you were not able to login into the windows azure management portal with live id. We are providing you with the summary, root cause analysis and information about permanent fix: Incident Title: You were unable to access Windows Azure Portal after Microsoft Account to Azure Active Directory account Migration. Service Impacted: Management Portal Incident Start Date and Time: 8/24/2012 4:30:00 PM Date and Time Service was Restored: 10/17/2012 12:00:00 AM Summary: Windows Azure performed a planned change from using the Microsoft account service (formerly Windows Live ID) to the Azure Active Directory (AAD) as its primary authentication mechanism on August 24th.   This change was made to enable future innovation in the area of authentication – particularly for organizationally owned identities, identity federation, stronger authentication methods and compliance certification.   While this migration was largely transparent to Windows Azure users, a small number of users whose sign-in names were part of a Windows Live Custom Domain were unable to login.   This incompatibility was not discovered during the Quality Assurance testing phase prior to the migration. Customer Impact: Customers whose sign-in names were part of a Windows Live Custom Domain were unable to sign-in the Management Portal after ~4:00 p.m. PST on August 24th, 2012.   We determined that the issue did impact at least 127 users in 98 of these Windows Live Custom Domains and had a maximum potential impact of 1,110 users in total. Root Cause: The root cause of the issue was an incompatibility in the AAD authentication service to handle logins from Microsoft accounts whose sign-in names were part of a Windows Live Custom Domains.  This issue was not discovered during the Quality Assurance testing phase prior to the migration from Microsoft Account (MSA) to AAD. Mitigations: The issue was mitigated for the majority of affected users by 8:20 a.m. PST on August 25th, 2012 by running some internal scripts to correct many known Windows Live Custom Domains.   The remaining affected domains fell into two categories: Windows Live Custom Domains that were not corrected by 8/25/2012. An additional 48 Windows Live Custom Domains were fixed in the weeks following the incident within 2 business days after the AAD team received an escalation from product support regarding those accounts. Windows Live Custom domains that were also provisioned in Office365. Some of the affected Windows Live Custom Domains had already been provisioned in AAD because their owners signed up for Office365 which is a service that also uses AAD.   In these cases the Azure customers had to work around the issue by renaming their Microsoft Account or using a different Microsoft Account to administer their Azure subscription. Permanent Fix: The Azure Active Directory team permanently fixed the issue for all customers on 10/17/2012 in an upgraded release of the AAD service.

  • Mousin' down the PathListBox

    - by T
    While modifying the standard media player with a new look and feel for Ineta Live I saw a unique opportunity to use their logo with a dotted I with and attached arc as the scrub control. So I created a PathListBox that I wanted an object to follow when a user did a click and drag action.  Below is how I solved the problem.  Please let me know if you have improvements or know of a completely different way.  I am always eager to learn. First, I created a path using the pen tool in Expression Blend (see the yellow line in image below).  Then I right clicked that path and chose [Path] --> [Make Layout Path].   That created a new PathListBox.  Then I chose the object I want to move down the new PathListBox and Placed it as a child in the Objects and Timeline window (see image below).  If the child object (the thing the user will click and drag) is XAML, it will move much smoother than images. Just as another side note, I wanted there to be no highlight when the user selects the “ball” to drag and drop.  This is done by editing the ItemContainerStyle under Additional Templates on the PathListBox.  Post a question if you need help on this and I will expand my explanation. Here is a pic of the object and the path I wanted it to follow.  I gave the path a yellow solid brush here so you could see it but when I lay this over another object, I will make the path transparent.   To animate this object down the path, the trick is to animate the Start number for the LayoutPath.  Not the StartItemIndex, the Start above Span. In order to enable animation when a user clicks and drags, I put in the following code snippets in the code behind. the DependencyProperties are not necessary for the Drag control.   namespace InetaPlayer { public partial class PositionControl : UserControl { private bool _mouseDown; private double _maxPlayTime; public PositionControl() { // Required to initialize variables InitializeComponent(); //mouse events for scrub control positionThumb.MouseLeftButtonDown += new MouseButtonEventHandler(ValueThumb_MouseLeftButtonDown); positionThumb.MouseLeftButtonUp += new MouseButtonEventHandler(ValueThumb_MouseLeftButtonUp); positionThumb.MouseMove += new MouseEventHandler(ValueThumb_MouseMove); positionThumb.LostMouseCapture += new MouseEventHandler(ValueThumb_LostMouseCapture); } // exposed for binding to real slider using a DependencyProperty enables animation, styling, binding, etc.... public double MaxPlayTime { get { return (double)GetValue(MaxPlayTimeProperty); } set { SetValue(MaxPlayTimeProperty, value); } } public static readonly DependencyProperty MaxPlayTimeProperty = DependencyProperty.Register("MaxPlayTime", typeof(double), typeof(PositionControl), null);   // exposed for binding to real slider using a DependencyProperty enables animation, styling, binding, etc....   public double CurrSliderValue { get { return (double)GetValue(CurrSliderValueProperty); } set { SetValue(CurrSliderValueProperty, value); } }   public static readonly DependencyProperty CurrSliderValueProperty = DependencyProperty.Register("CurrSliderValue", typeof(double), typeof(PositionControl), new PropertyMetadata(0.0, OnCurrSliderValuePropertyChanged));   private static void OnCurrSliderValuePropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { PositionControl control = d as PositionControl; control.OnCurrSliderValueChanged((double)e.OldValue, (double)e.NewValue); }   private void OnCurrSliderValueChanged(double oldValue, double newValue) { _maxPlayTime = (double) GetValue(MaxPlayTimeProperty); if (!_mouseDown) if (_maxPlayTime!=0) sliderPathListBox.LayoutPaths[0].Start = newValue / _maxPlayTime; else sliderPathListBox.LayoutPaths[0].Start = 0; }   //mouse control   void ValueThumb_MouseMove(object sender, MouseEventArgs e) { if (!_mouseDown) return; //get the offset of how far the drag has been //direction is handled automatically (offset will be negative for left move and positive for right move) Point mouseOff = e.GetPosition(positionThumb); //Divide the offset by 1000 for a smooth transition sliderPathListBox.LayoutPaths[0].Start +=mouseOff.X/1000; _maxPlayTime = (double)GetValue(MaxPlayTimeProperty); SetValue(CurrSliderValueProperty ,sliderPathListBox.LayoutPaths[0].Start*_maxPlayTime); }   void ValueThumb_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { _mouseDown = false; } void ValueThumb_LostMouseCapture(object sender, MouseEventArgs e) { _mouseDown = false; } void ValueThumb_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { _mouseDown = true; ((UIElement)positionThumb).CaptureMouse(); }   } }   I made this into a user control and exposed a couple of DependencyProperties in order to bind it to a standard Slider in the overall project.  This control is embedded into the standard Expression media player template and is used to replace the standard scrub bar.  When the player goes live, I will put a link here.

  • WPF ToggleButton changing image depending on state

    - by mack369
    I would like to use ToggleButton in following way: There are 5 different images and each of them should be displayed depending on current state: button disabled button enabled, unchecked button enabled, unchecked, pointed by mouse cursor button enabled, checked button enabled, checked, pointed by mouse cursor I've found a simple example with two images on http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/28c36bd2-2ef7-4232-9976-2a0967140e32 , but how to change the image depending on "checked" property? The second question: how can I avoid creating different styles for each button in my application? I'm using about 20 different buttons and each of them has different set of icons. So far I'm using only one icon, below my code. Is it possible to have common code (style and template) and to define the source of images in section where I want to create button (like in section 3 of my code)? <ControlTemplate x:Key="ToggleButtonTemplate" TargetType="{x:Type ToggleButton}"> <Grid> <Border x:Name="ContentBorder" CornerRadius="4" BorderBrush="Transparent" BorderThickness="1" Background="{DynamicResource ButtonOff}"> <ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="True"/> </Border> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsPressed" Value="true"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonOn}"/> </Trigger> <Trigger Property="IsChecked" Value="true"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonOn}"/> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonDisabled}"/> <Setter Property="Foreground" Value="{DynamicResource BorderDisabled}"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> <Style x:Key="ToggleButtonStyle" TargetType="{x:Type ToggleButton}"> <Setter Property="Width" Value="64" /> <Setter Property="Height" Value="64" /> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Template" Value="{DynamicResource ToggleButtonTemplate}" /> </Style> <ToggleButton IsChecked="{Binding Path=IsLectorModeEnabled}" Command="{Binding CmdLector}" Style="{DynamicResource ToggleButtonStyle}"> <Image Source="{DynamicResource LectorImage}" HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="None" /> </ToggleButton>

  • CodeIgniter: Passing variables via URL - alternatives to using GET

    - by John Durrant
    I'm new to CodeIgniter and have just discovered the difficulties using the GET method of passing variables via the URL (e.g. domain.com/page.php?var1=1&var2=2). I gather that one approach is to pass the variables in the URI segments but haven't quite figured out how to do that yet as it seems to create the expectation of having a function in the controller named as the specific URI segment???? Anyway Instead of using GET I've decided to use POST by adapting a submit button (disguised as a link) with the variables in hidden input fields. I've created the following solution which seems to work fine, but am wondering whether I'm on the right track here or whether there is an easier way of passing variables via a link within CodeIgniter? I've created the following class in application/libraries/ <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class C_variables { function variables_via_link($action, $link_text, $style, $link_data) { $attributes = array('style' => 'margin:0; padding:0; display: inline;'); echo form_open($action, $attributes); $attributes = array('class' => $style, 'name' => 'link'); echo form_submit($attributes, $link_text); foreach ($link_data as $key => $value){ echo form_hidden($key, $value); } echo form_close(); } } ?> With the following CSS: /* SUBMIT BUTTON AS LINK adapted from thread: http://forums.digitalpoint.com/showthread.php?t=403667 Cross browser support (apparently). */ .submit_as_link { background: transparent; border-top: 0; border-right: 0; border-bottom: 1px solid #00F; border-left: 0; color: #00F; display: inline; margin: 0; padding: 0; cursor: hand /* Added to show hand when hovering */ } *:first-child+html .submit_as_link { /* hack needed for IE 7 */ border-bottom: 0; text-decoration: underline; } * html .submit_as_link { /* hack needed for IE 5/6 */ border-bottom: 0; text-decoration: underline; } Link then created using the following code in the VIEW: <?php $link = new C_variables; $link_data=array('var1' => 1, 'var2' => 2); $link ->variables_via_link('destination_page', 'here is a link!', 'submit_as_link', $link_data); ?> Thanks for your help...

  • How to automatically resize an EditText widget (with some attributes) in a TableLayout

    - by steff
    Hi everyone, I have a layout issue. What I do is this: create TableLayout in xml with zero children: <TableLayout android:id="@+id/t_layout_contents" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/l_layout_tags" android:stretchColumns="1" android:paddingLeft="5dip" android:paddingRight="5dip" /> Insert first row programmatically in onCreate(): tLayoutContents = (TableLayout)findViewById(R.id.t_layout_contents); NoteElement nr_1 = new NoteElement(this); tLayoutContents.addView(nr_1); Class "NoteElement" extends TableRow. The 1st row just consists of a blank ImageView as a placeholder and an EditText to enter text. NoteElement's constructor looks like this: public NoteElement(Context c) { super(c); this.context = c; defaultText = c.getResources().getString(R.string.create_note_help_text); imageView = new ImageView(context); imageView.setImageResource(android.R.color.transparent); LayoutParams params = new LayoutParams(0); imageView.setLayoutParams(params); addView(imageView); addView(addTextField()); } Method addTextField() specifies the attributes for the EditText widget: private EditText addTextField() { editText = new EditText(context); editText.setImeOptions(EditorInfo.IME_ACTION_DONE); editText.setMinLines(4); editText.setRawInputType(InputType.TYPE_TEXT_FLAG_MULTI_LINE); editText.setHint(R.string.create_note_et_blank_text); editText.setAutoLinkMask(Linkify.ALL); editText.setPadding(5, 0, 0, 0); editText.setGravity(Gravity.TOP); editText.setVerticalScrollBarEnabled(true); LayoutParams params = new LayoutParams(1); editText.setLayoutParams(params); return editText; } So far, so good. But my problem occurs as soon as the available space for the chars is depleted. The EditText does not resize itself but switches to a single line EditText. I am desperatly looking for a way in which the EditText resizes itself in its height dynamically, being dependant on the inserted text length. Does anyone have a hint on this? Thanks & regards, steff

  • Force SSRS 2008 to use SSRS 2005 CSV rendering

    - by Kash
    We are upgrading our report server from SSRS 2005 to SSRS 2008 R2. I have an issue with CSV export rendering for SSRS 2008 where the SUM of columns are appearing on the right side of the detail values in 2008 instead of the left side like in 2005 as shown in the below blocks. 117 and 131 are the sums of Column2 and Column3 respectively. SSRS 2005 CSV Output Column2_1,Column3_1,Column2,Column3 117,131,1,2 117,131,1,2 117,131,60,23 117,131,30,15 117,131,25,89 SSRS 2008 CSV Output Column2,Column3,Column2_1,Column3_1 1,2,117,131 1,2,117,131 60,23,117,131 30,15,117,131 25,89,117,131 I understand that the CSV renderer has gone through major changes in SSRS 2008 R2 with the support for charts and gauges and more importantly it provides 2 modes: the default Excel mode and Compliant mode. But neither mode helps fix this issue. The Compliant mode was supposed to be closest to that of 2005 but apparently it is not close enough for my case. My Question: Is there a way to force SSRS 2008 fall back a report to a backward compatibility mode so that it exports into a 2005 CSV format? Solution tried: a) Using 2005-based CRIs Based on this article on ExecutionLog2, if SSRS 2008 R2 encounters a report whose auto-upgrade is not possible (e.g. reports that were built with 2005-based CustomReportItem controls), those particular reports will be processed with the old Yukon engine in a "transparent backwards-compatibility mode". It seems like it falls back to its previous version mode (2005) and attempts to render it. So I tried using a 2005-based barcode CustomReportItem and deployed to a SSRS 2008 R2 report server, but it shows the same result as before though it suppressed the barcode. This would be because SSRS 2008 R2 finds a way to suppress part of the report output and displays the rest. It would be great to find a 2005-based CRI that makes SSRS 2008 R2 process it with its old Yukon engine. Please note that quite possibly, even if it uses the "old Yukon processing engine", it might still use the new CSV renderer hence it shows the same output. If that is true, then this option is moot. b) Using XML renderer We can use a custom XML renderer and then use XSLT to convert the xml to appropriate CSV but this would mean that we need to convert all our 200 reports. Hence this is not feasible. Please note that we do not have the option of having SSRS 2005 and SSRS 2008 R2 deployed side by side.

  • Datatemplates while using theme does not work - WPF

    - by bobjink
    I am using the theme DarkExpression from WPF Futures. It does not seem to work well with datatemplates. Scenario 1: Here is how it looks like without datatemplates: Pic 1 Code: <ListView Name="playlistListView" ItemsSource="{Binding PlaylistList}" Margin="0" SelectionChanged="DatabindedPlaylistListView_SelectionChanged" Background="{x:Null}" Opacity="0.98"> <ListView.View> <GridView> <GridViewColumn Width="Auto" DisplayMemberBinding="{Binding Name}"> <GridViewColumnHeader HorizontalContentAlignment="Left" Content="Playlist" Tag="Playlist"/> </GridViewColumn> </GridView> </ListView.View> </ListView> Scenario 2: Here is how it looks like trying to use datatemplates while using the theme: Pic 2 Code: <ListView Name="playlistListView" ItemsSource="{Binding PlaylistList}" Margin="0" SelectionChanged="DatabindedPlaylistListView_SelectionChanged" Background="{x:Null}" Opacity="0.98"> <ListView.ItemTemplate> <DataTemplate> <Grid> <UserControls:SongDataTemplate Margin="4" /> </Grid> </DataTemplate> </ListView.ItemTemplate> </ListView> Scenario 3: Here is how it looks like trying to use datatemplates while overriding the theme: Pic3 Code: <UserControl.Resources> <Style x:Key="ListViewItemStretch" TargetType="{x:Type ListViewItem}"> <Setter Property="HorizontalContentAlignment" Value="Stretch"/> <Setter Property="Background" Value="Transparent" /> </Style> </UserControl.Resources> <Grid x:Name="LayoutRoot"> <ListView Name="playlistListView" ItemContainerStyle="{StaticResource ListViewItemStretch}" ItemsSource="{Binding PlaylistList}" Margin="0" SelectionChanged="DatabindedPlaylistListView_SelectionChanged" Background="{x:Null}" Opacity="0.98"> <ListView.ItemTemplate> <DataTemplate> <Grid> <UserControls:SongDataTemplate Margin="4" /> </Grid> </DataTemplate> </ListView.ItemTemplate> </ListView> I want to keep the theme style but I also want to use datatemplates to define how a playlist should look like. Any suggestions? Note: In scenario 2 and 3 I had to remove <ListView.View> <GridView> <GridViewColumn Width="Auto" DisplayMemberBinding="{Binding Name}"> <GridViewColumnHeader HorizontalContentAlignment="Left" Content="Playlist" Tag="Playlist"/> </GridViewColumn> </GridView> </ListView.View> Before the datatemplate would be used.

  • Memory leak on CollectionView.View.Refresh

    - by Dabblernl
    I have defined my binding thus: <TreeView ItemsSource="{Binding UsersView.View}" ItemTemplate="{StaticResource MyDataTemplate}" /> The CollectionViewSource is defined thus: private ObservableCollection<UserData> users; public CollectionViewSource UsersView{get;set;} UsersView=new CollectionViewSource{Source=users}; UsersView.SortDescriptions.Add( new SortDescription("IsLoggedOn",ListSortDirection.Descending); UsersView.SortDescriptions.Add( new SortDescription("Username",ListSortDirection.Ascending); So far, so good, this works as expected: The view shows first the users that are logged on in alphabetical order, then the ones that are not. However, the IsLoggedIn property of the UserData is updated every few seconds by a backgroundworker thread and then the code calls: UsersView.View.Refresh(); on the UI thread. Again this works as expected: users that log on are moved from the bottom of the view to the top and vice versa. However: Every time I call the Refresh method on the view the application hoards 3,5MB of extra memory, which is only released after application shutdown (or after an OutOfMemoryException...) I did some research and below is a list of fixes that did NOT work: The UserData class implements INotifyPropertyChanged Changing the underlying users collection does not make any difference at all: any IENumerable<UserData as a source for the CollectionViewSource causes the problem. -Changing the ColletionViewSource to a List<UserData (and refreshing the binding) or inheriting from ObservableCollection to get access to the underlying Items collection to sort that in place does not work. I am out of ideas! Help? EDIT: I found it: The Resource MyDataTemplate contains a Label that is bound to a UserData object to show one of its properties, the UserData objects being handed down by the TreeView's ItemsSource. The Label has a ContextMenu defined thus: <ContextMenu Background="Transparent" Width="325" Opacity=".8" HasDropShadow="True"> <PrivateMessengerUI:MyUserData IsReadOnly="True" > <PrivateMessengerUI:MyUserData.DataContext> <Binding Path="."/> </PrivateMessengerUI:MyUserData.DataContext> </PrivateMessengerUI:MyUserData> </ContextMenu> The MyUserData object is a UserControl that shows All properties of the UserData object. In this way the user first only sees one piece of data of a user and on a right click sees all of it. When I remove the MyUserData UserControl from the DataTemplate the memory leak disappears! How can I still implement the behaviour as specified above?

  • How can I use a custom TabItem control when databinding a TabControl in WPF?

    - by Russ
    I have a custom control that is derived from TabItem, and I want to databind that custom TabItem to a stock TabControl. I would rather avoid creating a new TabControl just for this rare case. This is what I have and I'm not having any luck getting the correct control to be loaded. In this case I want to use my ClosableTabItem control instead of the stock TabItem control. <TabControl x:Name="tabCases" IsSynchronizedWithCurrentItem="True" Controls:ClosableTabItem.TabClose="TabClosed" > <TabControl.ItemTemplate> <DataTemplate DataType="{x:Type Controls:ClosableTabItem}" > <TextBlock Text="{Binding Path=Id}" /> </DataTemplate> </TabControl.ItemTemplate> <TabControl.ContentTemplate> <DataTemplate DataType="{x:Type Entities:Case}"> <CallLog:CaseReadOnlyDisplay DataContext="{Binding}" /> </DataTemplate> </TabControl.ContentTemplate> </TabControl> EDIT: This is what I ended up with, rather than trying to bind a custom control. The "CloseCommand" im getting from a previous question. <Style TargetType="{x:Type TabItem}" BasedOn="{StaticResource {x:Type TabItem}}" > <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type TabItem}"> <Border Name="Border" Background="LightGray" BorderBrush="Black" BorderThickness="1" CornerRadius="25,0,0,0" SnapsToDevicePixels="True"> <StackPanel Orientation="Horizontal"> <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center" HorizontalAlignment="Center" ContentSource="Header" Margin="20,1,5,1"/> <Button Command="{Binding Path=CloseCommand}" Cursor="Hand" DockPanel.Dock="Right" Focusable="False" Margin="1,1,5,1" Background="Transparent" BorderThickness="0"> <Image Source="/Russound.Windows;component/Resources/Delete.png" Height="10" /> </Button> </StackPanel> </Border> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="FontWeight" Value="Bold" /> <Setter TargetName="Border" Property="Background" Value="LightBlue" /> <Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" /> <Setter TargetName="Border" Property="BorderBrush" Value="DarkBlue" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style>

  • Silverlight 4 Setting background color of textbox on focus

    - by Sean Riedel
    I am trying to set the background color of a Textbox to white on focus using a Style. My enabled Textbox has a Linear Gradient background by default: <Setter Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1"> <GradientStop Color="#e8e8e8" Offset="0.0" /> <GradientStop Color="#f3f3f3" Offset="0.25" /> <GradientStop Color="#f4f4f4" Offset="0.75" /> <GradientStop Color="#f4f4f4" Offset="1.0" /> </LinearGradientBrush> </Setter.Value> </Setter> I have a focus visual state defined: <VisualStateGroup x:Name="FocusStates"> <VisualState x:Name="Focused"> <Storyboard> <DoubleAnimation Storyboard.TargetName="FocusVisualElement" Storyboard.TargetProperty="Opacity" To="1" Duration="0"/> </Storyboard> </VisualState> Here is the rest of the Control Template: <Border x:Name="Border" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="1" Opacity="1" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}"> <Grid> <Border x:Name="ReadOnlyVisualElement" Opacity="0" Background="#5EC9C9C9"/> <Border x:Name="MouseOverBorder" BorderThickness="1" BorderBrush="Transparent"> <ScrollViewer x:Name="ContentElement" Padding="{TemplateBinding Padding}" BorderThickness="0" IsTabStop="False"/> </Border> </Grid> </Border> <Border x:Name="DisabledVisualElement" Background="#A5D7D7D7" BorderBrush="#A5D7D7D7" BorderThickness="{TemplateBinding BorderThickness}" Opacity="0" IsHitTestVisible="False"/> <Border x:Name="FocusVisualElement" Background="#A5ffffff" BorderBrush="#FF72c1ec" BorderThickness="{TemplateBinding BorderThickness}" Margin="1" Opacity="0" IsHitTestVisible="False"/> On the last Border tag is where I am trying to set the background to white (#ffffff). Right now I have the opacity at A5 which does turn the background white, however it also starts to obscure the text in the box. Any higher opacity makes the text invisible so I am pretty sure that setting the background of that border is not the right way to do this. Can I set the Background color of the ContentElement somehow through a StoryBoard? Thanks.

  • Cannot use standard android color attribute in custom color selector

    - by Manish Gupta
    So, android defines the following in themes.xml: <style name="Theme"> ... <item name="colorPressedHighlight">@color/legacy_pressed_highlight</item> </style> and: <style name="Theme.Holo"> ... <item name="colorPressedHighlight">@color/holo_blue_light</item> </style> I want to use this colorPressedHighlight as the background color for my custom Button when it is pressed. So I defined the following in res/color/app_button_background.xml: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:state_pressed="true" android:drawable="?android:colorPressedHighlight"/> <item android:drawable="@android:color/transparent" /> </selector> Finally, I define my custom ImageButton style: <style name="App_ImageButtonStyle" parent="@android:style/Widget.ImageButton"> <item name="android:gravity">center</item> <item name="android:background">@color/app_button_background</item> </style> I crash on app launch with the following call stack: 06-27 20:24:41.954: E/AndroidRuntime(532): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.StateListDrawable.inflate(StateListDrawable.java:178) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.Drawable.createFromXmlInner(Drawable.java:867) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.Drawable.createFromXml(Drawable.java:804) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.content.res.Resources.loadDrawable(Resources.java:1920) I know that directly accessing @color/legacy_pressed_highlight or @color/holo_blue_light instead of accessing them through the colorPressedHighlight fixes the crash but it does not solve the problem. Themes can vary, hence I need to access it through the colorPressedHighlight attribute. PS: I had a similar problem to which I haven't found an answer yet. Can someone please help!

  • SIFR 3.0 - Font Size

    - by Nick
    I have been working with SIFR 3.0 for some time now and the font-size never seems to work correctly. I understand the most basic concepts behind SIFR. SIFR runs when you load the page. It does some calculations one the size of the HTML rendered font and then replaces it with a flash movie that is roughly equal to that size. Because of this, you want to style your HTML font to match the size of your SIFR font as close as possible. My problem always comes up when trying to style these two font sizes to match. Let's say I want to use a SIFR font of Helvetica Neue Lt at about 32px. The HTML equivalent is something like Arial Narrow at about 36px with some negative letter spacing. So here is what I do. In sifr.css I'll write: @media screen { .sIFR-active h1 { visibility: hidden; z-index: 0 !important; font-size: 36px; } } Great, that gets the default HTML font the size I need. Now I need to update the flash SIFR font size. So I go into sifr-config.js and write something like this: sIFR.replace(HelveticaNeueThinCond, { selector: 'h1', css: '.sIFR-root { color: #762123; font-size: 32px; line-height: 1em; }', transparent: true }); So right now everything is working great. That is until my h1 text wraps more than one line. For some reason, when the text wraps it only shows the first line. It seems calculates the height wrong. This is very weird because I ran some tests. I took "visibility: hidden" off of "sIFR-active h1" to make sure that the HTML rendered text was the right size. It is, it takes up two lines. However, when the Flash replaces this text it gives it a min-height of one line of text. Odd. The only way I could find to fix this wrapping problem was to remove "font-size: 32px;" from "sIFR.replace(HelveticaNeueThinCond" in sifr-config. The problem I run into then is that it inherits the font-size set in sifr.css. Now the problem is that my HTML text is bigger then the SIFR text. So occasional my HTML text will wrap to a new line before my SIFR text leaving a big white space. So, how do I set two different font-size (one for my HTML text and one for my SIFR) without losing the wrapping. The only time I have been able to use the successfully is when I have a SIFR font that is so similar to a web safe font that they can share the same font-size attribute. Thanks

  • Trouble with OpenLayers Styles.

    - by Jenny
    So, tired of always seeing the bright orange default regular polygons, I'm trying to learn to style OpenLayers. I've had some success with: var layer_style = OpenLayers.Util.extend({},OpenLayers.Feature.Vector.style['default']); layer_style.fillColor = "#000000"; layer_style.strokeColor = "#000000"; polygonLayer = new OpenLayers.Layer.Vector("PolygonLayer"); polygonLayer.style = layer_style; But sine I am drawing my polygons with DrawFeature, my style only takes effect once I've finished drawing, and seeing it snap from bright orange to grey is sort of disconcerting. So, I learned about temporary styles, and tried: var layer_style = new OpenLayers.Style({"default": {fillColor: "#000000"}, "temporary": {fillColor: "#000000"}}) polygonLayer = new OpenLayers.Layer.Vector("PolygonLayer"); polygonLayer.style = layer_style; This got me a still orange square--until I stopped drawing, when it snapped into completely opaque black. I figured maybe I had to explicitly set the fillOpacity...no dice. Even when I changed both fill colors to be pink and blue, respectively, I still saw only orange and opaque black. I've tried messing with StyleMaps, since I read that if you only add one style to a style map, it uses the default one for everything, including the temporary style. var layer_style = OpenLayers.Util.extend({}, OpenLayers.Feature.Vector.style['default']); var style_map = new OpenLayers.StyleMap(layer_style); polygonLayer = new OpenLayers.Layer.Vector("PolygonLayer"); polygonLayer.style = style_map; That got me the black opaque square, too. (Even though that layer style works when not given to a map). Passing the map to the layer itself like so: polygonLayer = new OpenLayers.Layer.Vector("PolygonLayer", style_map); Didn't get me anything at all. Orange all the way, even after drawn. polygonLayer = new OpenLayers.Layer.Vector("PolygonLayer", {styleMap: style_map}); Is a lot more succesful: Orange while drawing, translucent black with black outline when drawn. Just like when I didn't use a map. Problem is, still no temporary... So, I tried initializing my map this way: var style_map = new OpenLayers.StyleMap({"default": layer_style, "temporary": layer_style}); No opaque square, but no dice for the temporary, either... Still orange snapping to black transparent. Even if I make a new Style (layer_style2), and set temporary to that, still no luck. And no luck with setting "select" style, either. What am I doing wrong? Temporary IS for styling things that are currently being sketched, correct? Is there some other way specific to the drawFeature Controller? Edit: setting extendDefault to be true doesn't seem to help, either... var style_map = new OpenLayers.StyleMap({"default": layer_style, "temporary": layer_style}, {"extendDefault": "true"});
