  • Placeholder images for testing reports

    - by Greg Low
    Lorem Ipsum has long been used to provide placeholder text for testing report and document layouts. Programs such as Microsoft Word have also included options for generating sample text. (For example, type =rand() anywhere in a blank area of a Microsoft Word document and hit enter).Matthew Roche and Donald Farmer both sent me a link the other day to an online service that provides placeholder images. This could be quite useful when testing report layouts in SQL Server Reporting Services.You'll find it here: http://lorempixel.com/Nice! As an example, here's a random sports image. Of course I have no idea what you'll see on this page :-)

    Future time: Since installing Ubuntu 12.04, I regularly have to fun fsck and reset my clock because it shows a 'future time' : Err.Msg. "superblock last mount time is in the future by less than a day, probably due to hardware clock being incorrectly set." FIXED. According to what I have read, it looks like I'm in the right place to get an answer. Following are my feeble attempts to rectify this annoyance: mjh@mjh-desktop:~$ sudo service ntp start [sudo] password for mjh: ntp: unrecognized service mjh@mjh-desktop:~$ mjh@mjh-desktop:~$ sudo apt-get install update Reading package lists...

    Taking example from Apple docs using predicates with Key-Paths NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY employees.firstName like 'Matthew'"]; Now, assume the employees has a bool field "isGood". The question: how do I select just those entities, having ALL of employees isGood==TRUE? I tried but failed with following predicates: "!(ANY employees.isGood != TRUE)" "(ALL employees.isGood == TRUE)" // Would be perfect, but throws an exception..

  • Brighton Rocks: UA Europe 2011

    - by ultan o'broin
    User Assistance Europe 2011 was held in Brighton, UK. Having seen Quadrophenia a dozen times, I just had to go along (OK, I wanted to talk about messages in enterprise applications). Sadly, it rained a lot, though that was still eminently more tolerable than being stuck home in Dublin during Bloomsday. So, here are my somewhat selective highlights and observations from the conference, massively skewed towards my own interests, as usual. Enjoyed Leah Guren's (Cow TC) great start ‘keynote’ on the Cultural Dimensions of Software Help Usage. Starting out by revisiting Hofstede's and Hall's work on culture (how many times I have done this for Multilingual magazine?) and then Neilsen’s findings on age as an indicator of performance, Leah showed how it is the expertise of the user that user assistance (UA) needs to be designed for (especially for high-end users), with some considerations made for age, while the gender and culture of users are not major factors. Help also needs to be contextual and concise, embedded close to the action. That users are saying things like “If I want help on Office, I go to Google ” isn't all that profound at this stage, but it is always worth reiterating how search can be optimized to return better results for users. Interestingly, regardless of user education level, the issue of information quality--hinging on the lynchpin of terminology reflecting that of the user--is critical. Major takeaway for me there. Matthew Ellison’s sessions on embedded help and demos were also impressive. Embedded help that is concise and contextual is definitely a powerful UX enabler, and I’m pleased to say that in Oracle Fusion Applications we have embraced the concept fully. Matthew also mentioned in his session about successful software demos that the principle of modality with demos is a must. Look no further than Oracle User Productivity Kit demos See It!, Try It!, Know It, and Do It! modes, for example. I also found some key takeaways in the presentation by Marie-Louise Flacke on notes and warnings. Here, legal considerations seemed to take precedence over providing any real information to users. I was delighted when Marie-Louise called out the Oracle JDeveloper documentation as an exemplar of how to use notes and instructions instead of trying to scare the bejaysus out of people and not providing them with any real information they’d find useful instead. My own session on designing messages for enterprise applications was well attended. Knowing your user profiles (remember user expertise is the king maker for UA so write for each audience involved), how users really work, the required application business and UI rules, what your application technology supports, and how messages integrate with the enterprise help desk and support policies and you will go much further than relying solely on the guideline of "writing messages in plain language". And, remember the value in warnings and confirmation messages too, and how you can use them smartly. I hope y’all got something from my presentation and from my answers to questions afterwards. Ellis Pratt stole the show with his presentation on applying game theory to software UA, using plenty of colorful, relevant examples (check out the Atlassian and DropBox approaches, for example), and striking just the right balance between theory and practice. Completely agree that the approach to take here is not to make UA itself a game, but to invoke UA as part of a bigger game dynamic (time-to-task completion, personal and communal goals, personal achievement and status, and so on). Sure there are gotchas and limitations to gamification, and we need to do more research. However, we'll hear a lot more about this subject in coming years, particularly in the enterprise space. I hope. I also heard good things about the different sessions about DITA usage (including one by Sonja Fuga that clearly opens the door for major innovation in the community content space using WordPress), the progressive disclosure of information (Cerys Willoughby), an overview of controlled language (or "information quality", as I like to position it) solutions and rationale by Dave Gash, and others. I also spent time chatting with Mike Hamilton of MadCap Software, who showed me a cool demo of their Flare product, and the Lingo translation solution. I liked the idea of their licensing model for workers-on-the-go; that’s smart UX-awareness in itself. Also chatted with Julian Murfitt of Mekon about uptake of DITA in the enterprise space. In all, it's worth attending UA Europe. I was surprised, however, not to see conference topics about mobile UA, community conversation and content, and search in its own right. These are unstoppable forces now, and the latter is pretty central to providing assistance now to all but the most irredentist of hard-copy fetishists or advanced technical or functional users working away on the back end of applications and systems. Only saw one iPad too (says the guy who carries three laptops). Tweeting during the conference was pretty much nonexistent during the event, so no community energy there. Perhaps all this can be addressed next year. I would love to see the next UA Europe event come to Dublin (despite Bloomsday, it's not a bad place place, really) now that hotels are so cheap and all. So, what is my overall impression of the state of user assistance in Europe? Clearly, there are still many people in the industry who feel there is something broken with the traditional forms of user assistance (particularly printed doc) and something needs to be done about it. I would suggest they move on and try and embrace change, instead. Many others see new possibilities, offered by UX and technology, as well as the reality of online user behavior in an increasingly connected world and that is encouraging. Such thought leaders need to be listened to. As Ellis Pratt says in his great book, Trends in Technical Communication - Rethinking Help: “To stay relevant means taking a new perspective on the role (of technical writer), and delivering “products” over and above the traditional manual and online Help file... there are a number of new trends in this field - some complementary, some conflicting. Whatever trends emerge as the norm, it’s likely the status quo will change.” It already has, IMO. I hear similar debates in the professional translation world about the onset of translation crowd sourcing (the Facebook model) and machine translation (trust me, that battle is over). Neither of these initiatives has put anyone out of a job and probably won't, though the nature of the work might change. If anything, such innovations have increased the overall need for professional translators as user expectations rise, new audiences emerge, and organizations need to collate and curate user-generated content, combining it with their own. Perhaps user assistance professionals can learn from other professions and grow accordingly.

  • Guest Post: Using IronRuby and .NET to produce the &lsquo;Hello World of WPF&rsquo;

    - by Eric Nelson
    [You might want to also read other GuestPosts on my blog – or contribute one?] On the 26th and 27th of March (2010) myself and Edd Morgan of Microsoft will be popping along to the Scottish Ruby Conference. I dabble with Ruby and I am a huge fan whilst Edd is a “proper Ruby developer”. Hence I asked Edd if he was interested in creating a guest post or two for my blog on IronRuby. This is the second of those posts. If you should stumble across this post and happen to be attending the Scottish Ruby Conference, then please do keep a look out for myself and Edd. We would both love to chat about all things Ruby and IronRuby. And… we should have (if Amazon is kind) a few books on IronRuby with us at the conference which will need to find a good home. This is me and Edd and … the book: Order on Amazon: http://bit.ly/ironrubyunleashed Using IronRuby and .NET to produce the ‘Hello World of WPF’ In my previous post I introduced, to a minor extent, IronRuby. I expanded a little on the basics of by getting a Rails app up-and-running on this .NET implementation of the Ruby language — but there wasn't much to it! So now I would like to go from simply running a pre-existing project under IronRuby to developing a whole new application demonstrating the seamless interoperability between IronRuby and .NET. In particular, we'll be using WPF (Windows Presentation Foundation) — the component of the .NET Framework stack used to create rich media and graphical interfaces. Foundations of WPF To reiterate, WPF is the engine in the .NET Framework responsible for rendering rich user interfaces and other media. It's not the only collection of libraries in the framework with the power to do this — Windows Forms does the trick, too — but it is the most powerful and flexible. Put simply, WPF really excels when you need to employ eye candy. It's all about creating impact. Whether you're presenting a document, video, a data entry form, some kind of data visualisation (which I am most hopeful for, especially in terms of IronRuby - more on that later) or chaining all of the above with some flashy animations, you're likely to find that WPF gives you the most power when developing any of these for a Windows target. Let's demonstrate this with an example. I give you what I like to consider the 'hello, world' of WPF applications: the analogue clock. Today, over my lunch break, I created a WPF-based analogue clock using IronRuby... Any normal person would have just looked at their watch. - Twitter The Sample Application: Click here to see this sample in full on GitHub. Using Windows Presentation Foundation from IronRuby to create a Clock class Invoking the Clock class   Gives you The above is by no means perfect (it was a lunch break), but I think it does the job of illustrating IronRuby's interoperability with WPF using a familiar data visualisation. I'm sure you'll want to dissect the code yourself, but allow me to step through the important bits. (By the way, feel free to run this through ir first to see what actually happens). Now we're using IronRuby - unlike my previous post where we took pure Ruby code and ran it through ir, the IronRuby interpreter, to demonstrate compatibility. The main thing of note is the very distinct parallels between .NET namespaces and Ruby modules, .NET classes and Ruby classes. I guess there's not much to say about it other than at this point, you may as well be working with a purely Ruby graphics-drawing library. You're instantiating .NET objects, but you're doing it with the standard Ruby .new method you know from Ruby as Object#new — although, the root object of all your IronRuby objects isn't actually Object, it's System.Object. You're calling methods on these objects (and classes, for example in the call to System.Windows.Controls.Canvas.SetZIndex()) using the underscored, lowercase convention established for the Ruby language. The integration is so seamless. The fact that you're using a dynamic language on top of .NET's CLR is completely abstracted from you, allowing you to just build your software. A Brief Note on Events Events are a big part of developing client applications in .NET as well as under every other environment I can think of. In case you aren't aware, event-driven programming is essentially the practice of telling your code to call a particular method, or other chunk of code (a delegate) when something happens at an unpredictable time. You can never predict when a user is going to click a button, move their mouse or perform any other kind of input, so the advent of the GUI is what necessitated event-driven programming. This is where one of my favourite aspects of the Ruby language, blocks, can really help us. In traditional C#, for instance, you may subscribe to an event (assign a block of code to execute when an event occurs) in one of two ways: by passing a reference to a named method, or by providing an anonymous code block. You'd be right for seeing the parallel here with Ruby's concept of blocks, Procs and lambdas. As demonstrated at the very end of this rather basic script, we are using .NET's System.Timers.Timer to (attempt to) update the clock every second (I know it's probably not the best way of doing this, but for example's sake). Note: Diverting a little from what I said above, the ticking of a clock is very predictable, yet we still use the event our Timer throws to do this updating as one of many ways to perform that task outside of the main thread. You'll see that all that's needed to assign a block of code to be triggered on an event is to provide that block to the method of the name of the event as it is known to the CLR. This drawback to this is that it only allows the delegation of one code block to each event. You may use the add method to subscribe multiple handlers to that event - pushing that to the end of a queue. Like so: def tick puts "tick tock" end timer.elapsed.add method(:tick) timer.elapsed.add proc { puts "tick tock" } tick_handler = lambda { puts "tick tock" } timer.elapsed.add(tick_handler)   The ability to just provide a block of code as an event handler helps IronRuby towards that very important term I keep throwing around; low ceremony. Anonymous methods are, of course, available in other more conventional .NET languages such as C# and VB but, as usual, feel ever so much more elegant and natural in IronRuby. Note: Whether it's a named method or an anonymous chunk o' code, the block you delegate to the handling of an event can take arguments - commonly, a sender object and some args. Another Brief Note on Verbosity Personally, I don't mind verbose chaining of references in my code as long as it doesn't interfere with performance - as evidenced in the example above. While I love clean code, there's a certain feeling of safety that comes with the terse explicitness of long-winded addressing and the describing of objects as opposed to ambiguity (not unlike this sentence). However, when working with IronRuby, even I grow tired of typing System::Whatever::Something. Some people enjoy simply assuming namespaces and forgetting about them, regardless of the language they're using. Don't worry, IronRuby has you covered. It is completely possible to, with a call to include, bring the contents of a .NET-converted module into context of your IronRuby code - just as you would if you wanted to bring in an 'organic' Ruby module. To refactor the style of the above example, I could place the following at the top of my Clock class: class Clock include System::Windows::Shape include System::Windows::Media include System::Windows::Threading # and so on...   And by doing so, reduce calls to System::Windows::Shapes::Ellipse.new to simply Ellipse.new or references to System::Windows::Threading::DispatcherPriority.Render to a friendlier DispatcherPriority.Render. Conclusion I hope by now you can understand better how IronRuby interoperates with .NET and how you can harness the power of the .NET framework with the dynamic nature and elegant idioms of the Ruby language. The manner and parlance of Ruby that makes it a joy to work with sets of data is, of course, present in IronRuby — couple that with WPF's capability to produce great graphics quickly and easily, and I hope you can visualise the possibilities of data visualisation using these two things. Using IronRuby and WPF together to create visual representations of data and infographics is very exciting to me. Although today, with this project, we're only presenting one simple piece of information - the time - the potential is much grander. My day-to-day job is centred around software development and UI design, specifically in the realm of healthcare, and if you were to pay a visit to our office you would behold, directly above my desk, a large plasma TV with a constantly rotating, animated slideshow of charts and infographics to help members of our team do their jobs. It's an app powered by WPF which never fails to spark some conversation with visitors whose gaze has been hooked. If only it was written in IronRuby, the pleasantly low ceremony and reduced pre-processing time for my brain would have helped greatly.

  • Edd strikes again &ndash; IronRuby for Rubyists on InfoQ

    - by Eric Nelson
    Colleague, friend and generally top guy on IronRuby Edd Morgan has just been published over on InfoQ. To wet the appetite… a snippet or three. IronRuby for Rubyists IronRuby is Microsoft's implementation of the Ruby language we all know and love with the added bonus of interoperability with the .NET framework — the Iron in the name is actually an acronym for 'Implementation running on .NET'. It's supported by the .NET Common Language Runtime as well as, albeit unofficially, the Mono project. You'd be forgiven for harbouring some question in your mind about running a dynamic language such as Ruby atop the CLR - that's where the DLR (Dynamic Language Runtime) comes in. The DLR is Microsoft's way of providing dynamic language capability on top of the CLR. Both IronRuby and the DLR are, as part of Microsoft's commitment to open source software, available as part of the Microsoft Public License on GitHub and CodePlex respectively… And Metaprogramming with IronRuby The art and science of metaprogramming — especially in Ruby, where it's an absolute joy — is something that could very easily span an entire article. As you would hope, IronRuby code is fully able to manipulate itself allowing you to bend your classes to your whim just as you would expect with a good dynamic language… And Riding the irails? So let's get to the point. I think it's a solid bet to make that a large proportion of Ruby programmers are familiar with the Rails framework - perhaps it's even safe to assume that most were first led to the Ruby language by the siren song of the Rails framework itself. Long story short, IronRuby is compatible enough to run your Rails app… Now… get yourself over to the full article and also check out some of Edds other work below.

  • 7.0.1 and Photoshop openGL requirements

    - by mcgd
    Hi, I'm running Workstation 7.0.1 on a 64-bit Linux host, with a Vista guest, and the Aero theme works a treat - full marks for getting that working! However, when running Photoshop there are some operations (like interactive image rotation) that seem to require graphics support that VMWare doesn't have - attempting to do these operations returns an error that the functionality "only works with OpenGL enabled windows". It seems that it needs OpenGL 2.0 and Shader Model 3.0 which I gather are supported under Workstation 7 - do I need to put in additional settings of some kind? I've updated to the right version of VMWare Tools, and the video driver is listed as "VMWare SVGA 3D (Microsoft Corporation - WDDM)". I see that in 6.5 there was an option to switch between the beta WDDM driver and the SVGAII driver, but I assume the features of both of these would have been merged into the standard driver in 7.0? Thanks -Matthew
