  • What do I need to do if I want all typeof(MyEnum)'s to be handled with MyEnumModelBinder?

    - by Byron Sommardahl
    I have an Enum that appears in several of my models. For the most part, the DefaultModelBinder handles binding to my models beautifully. That it, until it gets to my Enum... it always returns the first member in the Enum no matter what is handed it by the POST. My googling leads me to believe I need to have a model binder that knows how to handle Enums. I found an excellent article on a possible custom modelBinder for Enums: http://eliasbland.wordpress.com/2009/08/08/enumeration-model-binder-for-asp-net-mvc/. I've since implemented that modelBinder and registered it in my global.asax: ModelBinders.Binders[typeof (MyEnum)] = new EnumBinder<MyEnum>(MyEnum.MyDefault); For some reason, the EnumBinder< isn't being called when the model I'm binding to has MyEnum. I have a breakpoint in the .BindModel() method and it never break. Also, my model hasn't changed after modelBinding. Have I done everything? What am I missing here?

  • How to put a pre-existing sqlite file into <Application_Home>/Library/?

    - by Byron Cox
    My app uses Core Data. I have run the app in the simulator which has successfully created and populated the corresponding sqlite file. I now want to get this pre-existing sqlite file on to an actual device and be part of my app. I have located the simulator generated sqlite file at /Library/Application Support/iPhone Simulator/6.0/Applications/identifier/Documents/myapp.sqlite and dragged it into Xcode. This has added it to my application bundle but not in an appropriate directory (with the consequence that the sqlite file can be read but not written to). From reading about the file system I believe that the best place to put the sqlite file would be in a custom directory 'Database' under Application_Home/Library/. I don't seem to be able to do this within Xcode and despite searching I am unable to figure out how to do the following: (1) Create a sub-directory called 'Database' in Application_Home/Library/ ? (2) Transfer the sqlite file to my newly created 'Database' directory ? Many thanks to @Daij-Djan of his answer below. One other question: the path to the sqlite file will be used by the persistent store coordinator. Now depending on the size of the sqlite file it may take a while to copy or move. How can you ensure that the example code provided by @Daij-Djan has executed and finished before the persistent store coordinator tries to reference the sqlite file? Thanks for any help in advance.

  • How to hide/show div using jQuery without altering dimensions?

    - by Byron S
    I have a div that is holding a google chart: <div id="chart_div" style="width: 600px; height: 300px;"></div> It has one CSS property: display: none. On the click of a button, I would like to have the chart be displayed using jQuery hide() and show(). It's working, however, the chart's dimensions are set to something different than I have specified and refuse to change to what I have specified. Here is my jquery code: $(document).ready(function(){ var chart = $('#chart_div'); $('#submit').click(function(){ chart.show('slow'); }); }); Let me know if theres any more code you would like to see. By the way, the chart div is not being contained in anything else so that isn't the problem.

  • Magento - save quote_address on cart addAction using observer

    - by Byron
    I am writing a custom Magento module that gives rate quotes (based on an external API) on the product page. After I get the response on the product page, it adds some of the info from the response into the product view's form. The goal is to save the address (as well as some other things, but those can be in the session for now). The address needs to be saved to the quote, so that the checkout (onestepcheckout, free version) will automatically fill those values in (city, state, zip, country, shipping method [of which there are 3]) and load the rate quote via ajax (which it's already doing). I have gone about this by using an Observer, and watching for the cart events. I fill in the address and save it. When I end up on the cart page or checkout page ~4/5 times the data is lost, and the sql table shows that the quote_address is getting save with no address info, even though there is an explicit save. The observer method's I've used are: checkout_cart_update_item_complete checkout_cart_product_add_after The code saving is: (I've tried this with the address, quote and cart all not calling save() with the same results, as well as not calling setQuote() $quote->getShippingAddress() ->setCountryId($params['estimate_to_country']) ->setCity($params['estimate_to_city']) ->setPostcode($params['estimate_to_zip_code']) ->setRegionId($params['estimate_to_state_code']) ->setRegion($params['estimate_to_state']) ->setCollectShippingRates(true) ->setShippingMethod($params['carrier_method']) ->setQuote($quote) ->save(); $quote->getBillingAddress() ->setCountryId($params['estimate_to_country']) ->setCity($params['estimate_to_city']) ->setPostcode($params['estimate_to_zip_code']) ->setRegionId($params['estimate_to_state_code']) ->setRegion($params['estimate_to_state']) ->setCollectShippingRates(true) ->setShippingMethod($params['carrier_method']) ->setQuote($quote) ->save(); $quote->save(); $cart->save(); I imagine there's a good chance this is not the best place to save this info, but I am not quite sure. I was wondering if there is a good place to do this without overriding a whole controller to save the address on the add to cart action. Thanks so much, let me know if I need to clarify

  • What is this type of programming called (creating an online network)?

    - by Byron S
    For practice purposes, I am looking to build an application that is capable of connecting multiple devices through the internet. It will be similar to craigslist, but I want to make this as an iOS application. I have very little experience with web services, as the most I've done is pulled an RSS feed onto the screen. How are these things normally done? If it's similar to a message board, is it as simple as having a database in a server/cloud, and giving all users access to it? Or is it more complicated than that? How should I begin to learn more about the backend? What kind of services are usually used in this kind of thing? The only database I've used is Core Data.

  • Ada and 'The Book'

    - by Phil Factor
    The long friendship between Charles Babbage and Ada Lovelace created one of the most exciting and mysterious of collaborations ever to have resulted in a technological breakthrough. The fireworks that created by the collision of two prodigious mathematical and creative talents resulted in an invention, the Analytical Engine, which went on to change society fundamentally. However, beyond that, we just don't know what the bulk of their collaborative work was about:;  it was done in strictest secrecy. Even the known outcome of their friendship, the first programmable computer, was shrouded in mystery. At the time, nobody, except close friends and family, had any idea of Ada Byron's contribution to the invention of the ‘Engine’, and how to program it. Her great insight was published in August 1843, under the initials AAL, standing for Ada Augusta Lovelace, her title then being the Countess of Lovelace. It was contained in a lengthy ‘note’ to her translation of a publication that remains the best description of Babbage's amazing Analytical Engine. The secret identity of the person behind those enigmatic initials was finally revealed by Prince de Polignac who, seventy years later, wrote to Ada's daughter to seek confirmation that her mother had, indeed, been the author of the brilliant sentences that described so accurately how Babbage's mechanical computer could be programmed with punch-cards. L.F. Menabrea's paper on the Analytical Engine first appeared in the 'Bibliotheque Universelle de Geneve' in October 1842, and Ada translated it anonymously for Taylor's 'Scientific Memoirs'. Charles Babbage was surprised that she had not written an original paper as she already knew a surprising amount about the way the machine worked. He persuaded her to at least write some explanatory notes. These notes ended up extending to four times the length of the original article and represented the first published account of how a machine could be programmed to perform any calculation. Her example of programming the Bernoulli sequence would have worked on the Analytical engine had the device’s construction been completed, and gave Ada an unassailable claim to have invented the art of programming. What was the reason for Ada's secrecy? She was the only legitimate child of Lord Byron, who was probably the best known celebrity of the age, so she was already famous. She was a senior aristocrat, with titles, a fortune in money and vast estates in the Midlands. She had political influence, and was the cousin of Lord Melbourne, who was the Prime Minister at that time. She was friendly with the young Queen Victoria. Her mathematical activities were a pastime, and not one that would be considered by others to be in keeping with her roles and responsibilities. You wouldn't dare to dream up a fictional heroine like Ada. She was dazzlingly beautiful and talented. She could speak several languages fluently, and play some musical instruments with professional skill. Contemporary accounts refer to her being 'accomplished in science, art and literature'. On top of that, she was a brilliant mathematician, a talent inherited from her mother, Annabella Milbanke. In her mother's circle of literary and scientific friends was Charles Babbage, and Ada's friendship with him dates from her teenage zest for Mathematics. She was one of the first people he'd ever met who understood what he had attempted to achieve with the 'Difference Engine', and with whom he could converse as intellectual equals. He arranged for her to have an education from the most talented academics in the country. Ada melted the heart of the cantankerous genius to the point that he became a faithful and loyal father-figure to her. She was one of the very few who could grasp the principles of the later, and very different, ‘Analytical Engine’ which was designed from the start to tackle a variety of tasks. Sadly, Ada Byron's life ended less than a decade after completing the work that assured her long-term fame, in November 1852. She was dying of cancer, her gambling habits had caused her to run up huge debts, she'd had more than one affairs, and she was being blackmailed. Her brilliant but unempathic mother was nursing her in her final illness, destroying her personal letters and records, and repaying her debts. Her husband was distraught but helpless. Charles Babbage, however, maintained his steadfast paternalistic friendship to the end. She appointed her loyal friend to be her executor. For years, she and Babbage had been working together on a secret project, known only as 'The Book'. We have a clue to what it was in a letter written by her nine years earlier, on 11th August 1843. It was a joint project by herself and Lord Lovelace, her husband, and was intended to involve Babbage's 'undivided energies'. It involved 'consulting your Engine' (it required Babbage’s computer). The letter gives no hint about the project except for the high-minded nature of its purpose, and its highly mathematical nature.  From then on, the surviving correspondence between the two gives only veiled references to 'The Book'. There isn't much, since Babbage later destroyed any letters that could have damaged her reputation within the Establishment. 'I cannot spare the book today, which I am very sorry for. At the moment I want it for constant reference, but I think you can have it tomorrow' (Oct 1844)  And 'I will send you the book directly, and you can say, when you receive it, how long you will want to keep it'. (Nov 1844)  The two of them were obviously intent on the work: She writes, four years later, 'I have an engagement for Wednesday which will prevent me from attending to your wishes about the book' (Dec 1848). This was something that they both needed to work on, but could not do in parallel: 'I will send the book on Tuesday, and it can be left with you till Friday' (11 Feb 1849). After six years work, it had been so well-handled that it was beginning to fall apart: 'Don't forget the new cover you promised for the book. The poor book is very shabby and wants one' (20 Sept 1849). So what was going on? The word 'book' was not a code-word: it was a real book, probably a 'printer's blank', plain paper, but properly bound so printers and publishers could show off how the published work might look. The hints from the correspondence are of advanced mathematics. It is obvious that the book was travelling between them, back and forth, each one working on it for less than a week before passing it back. Ada and her husband were certainly involved in gambling large sums of money on the horses, and so most biographers have concluded that the three of them were trying to calculate the mathematical odds on the horses. This theory has three large problems. Firstly, Ada's original letter proposing the project refers to its high-minded nature. Babbage was temperamentally opposed to gambling and would scarcely have given so much time to the project, even though he was devoted to Ada. Secondly, Babbage would have very soon have realized the hopelessness of trying to beat the bookies. This sort of betting never attracts his type of intellectual background. The third problem is that any work on calculating the odds on horses would not need a well-thumbed book to pass back and forth between them; they would have not had to work in series. The original project was instigated by Ada, along with her husband, William King-Noel, 1st Earl of Lovelace. Charles Babbage was invited to join the project after the couple had come up with the idea. What could William have contributed? One might assume that William was a Bertie Wooster character, addicted only to the joys of the turf, but this was far from the truth. He was a scientist, a Cambridge graduate who was later elected to be a Fellow of the Royal Society. After Eton, he went to Trinity College, Cambridge. On graduation, he entered the diplomatic service and acted as secretary under Lord Nugent, who was Lord Commissioner of the Ionian Islands. William was very friendly with Babbage too, able to discuss scientific matters on equal terms. He was a capable engineer who invented a process for bending large timbers by the application of steam heat. He delivered a paper to the Institution of Civil Engineers in 1849, and received praise from the great engineer, Isambard Kingdom Brunel. As well as being Lord Lieutenant of the County of Surrey for most of Victoria's reign, he had time for a string of scientific and engineering achievements. Whatever the project was, it is unlikely that William was a junior partner. After Ada's death, the project disappeared. Then, two years later, Babbage, through one of his occasional outbursts of temper, demonstrated that he was able to decrypt one of the most powerful of secret codes, Vigenère's autokey cipher.  All contemporary diplomatic and military messages used a variant of this cipher. Babbage had made three important discoveries, namely, the mathematical law of this cipher, the principle of the key periodicity, and the technique of the symmetry of position. The technique is now known as the Kasiski examination, also called the Kasiski test, but Babbage got there first. At one time, he listed amongst his future projects, the writing of a book 'The Philosophy of Decyphering', but it never came to anything. This discovery was going to change the course of history, since it was used to decipher the Russians’ military dispatches in the Crimean war. Babbage himself played a role during the Crimean War as a cryptographical adviser to his friend, Rear-Admiral Sir Francis Beaufort of the Admiralty. This is as much as we can be certain about in trying to make sense of the bulk of the time that Charles Babbage and Ada Lovelace worked together. Nine years of intensive work, involving the 'Engine' and a great deal of mathematics and research seems to have been lost: or has it? I've argued in the past http://www.simple-talk.com/community/blogs/philfactor/archive/2008/06/13/59614.aspx that the cracking of the Vigenère autokey cipher, was a fundamental motive behind the British Government's support and funding of the 'Difference Engine'. The Duke of Wellington, whose understanding of the military significance of being able to read enemy dispatches, was the most steadfast advocate of the project. If the three friends were actually doing the work of cracking codes by mathematical techniques that used the techniques of key periodicity, and symmetry of position (the use of a book being passed quickly to and fro is very suggestive), intending to then use the 'Engine' to do the routine cracking of each dispatch, then this is a rather different story. The project was Ada and William's idea. (William had served in the diplomatic service and would be familiar with the use of codes). This makes Ada Lovelace the initiator of a project which, by giving both Britain, and probably the USA, a diplomatic and military advantage in the second part of the Nineteenth century, changed world history. Ada would never have wanted any credit for cracking the cipher, and developing the method that rendered all contemporary military and diplomatic ciphering techniques nugatory; quite the reverse. And it is clear from the gaps in the record of the letters between the collaborators that the evidence was destroyed, probably on her request by her irascible but intensely honorable executor, Charles Babbage. Charles Babbage toyed with the idea of going public, but the Crimean war put an end to that. The British Government had a valuable secret, and intended to keep it that way. Ada and Charles had quite often discussed possible moneymaking projects that would fund the development of the Analytic Engine, the first programmable computer, but their secret work was never in the running as a potential cash cow. I suspect that the British Government was, even then, working on the concealment of a discovery whose value to the nation depended on it remaining so. The success of code-breaking in the Crimean war, and the American Civil war, led to the British and Americans  subsequently giving much more weight and funding to the science of decryption. Paradoxically, this makes Ada's contribution even closer to the creation of Colossus, the first digital computer, at Bletchley Park, specifically to crack the Nazi’s secret codes.

    - by user69486
    I have a Macbook Pro with Snow Leopard and Windows 7 Pro (Bootcamp). I have encyrpted all the company computers with truecrypt and now its the Macbooks turn. Will Truecrypt only encrypt the Win 7 partition and will it disable Bootcamp, or would it install after Bootcamp, whereby after I select either the OS X or Windows partition under Bootcamp, the Truecrypt encryption for Win 7 would be activated? Thanks in advance. Byron

  • To the world, with love

    - by kaleidoscope
    kaleidoscope 1817, lit. "observer of beautiful forms," coined by its inventor, Sir David Brewster (1781-1868), from Gk. kalos "beautiful" + eidos "shape" (see -oid) + -scope, on model of telescope, etc. Figurative meaning "constantly changing pattern" is first attested 1819 in Lord Byron, whose publisher had sent him one. Let’s start by setting some context here. “We” are not a single blogger but a bunch of like minded people who will be contributing to this blog. We belong to a team led by some folks possessed by innovation, and this has rubbed on us in a good way. How it started It all started with initiative from Girish, A. A big thank you, goes to him. To get it straight from the horse’ mouth: What is it? - Everybody (as per the published schedule) post a small write-up (not more than say 5/6 lines) regarding any Azure related concept. - We shall consolidate all these mails (which would be 5/week) and quickly discuss/brain storm about it, end of the week i.e. on Fridays. What’s the benefit? - This should make our basic Azure concepts rock-solid. - As part of this exercise, we will have a very good collection of Azure FAQs. As the team grew stronger, so did the contributions and after almost 3 months of regular contributions and weekly discussions we thought of sharing the content with the world at large. Afterall we are IT folks and the big I in IT is there for a reason. :) The road ahead We will post the entire collection as time permits. Tagged by contributor. Going forward each contributor will post individually adding his/her specific tag. Get blogging!!

  • Woman Is the World's First Computer Programmer? [closed]

    - by Sveta Bondarenko
    This week, on 10th December, we celebrate the 197th birth anniversary of Ada Lovelace, often considered as the world's first computer programmer. Ada became famous not only as a daughter of romantic poet Lord Byron but also as an outstanding 19th century mathematician. Her works on analytical engine are recognized as the first algorithm intended to be processed by a machine. Women always played a crucial role in the computer science evolution, but unfortunately, they are considered to be not so good at programming and engineering as men. Even though the fair sex makes up a growing portion of computer and Internet users, there is still a large gender gap in the field of Computer Science. But all is not lost! According to the study women's enrollment in the computer science raised from 7 percent in 1995 to 42 percent in 2000. And it is still increasing. Soon women will take a well-deserved position among the world's top computer programmers. After all, a number of notable female computer pioneers such as Ada Lovelace, Grace Hopper, and Anita Borg have proven that women make great computer scientists. But will women make great contributions to the modern technologies industry? Or successful and famous female computer programmer is just a pipe dream?

  • Visual-C++ Linker Error

    - by LordByron
    I have a class called MODEL in which public static int theMaxFrames resides. The class is defined in its own header file. theMaxFrames is accessed by a class within the MODEL class and by one function, void set_up(), which is also in the MODEL class. The Render.cpp source file contains a function which calls a function in the Direct3D.cpp source file which in turn calls the set_up() function through a MODEL object. This is the only connection between these two source files and theMaxFrames. When I try to compile my code I get the following error messages: 1Direct3D.obj : error LNK2001: unresolved external symbol "public: static int MODEL::theMaxFrames" (?theMaxFrames@MODEL@@2HA) 1Render.obj : error LNK2001: unresolved external symbol "public: static int MODEL::theMaxFrames" (?theMaxFrames@MODEL@@2HA) 1C:\Users\Byron\Documents\Visual Studio 2008\Projects\xFileViewer\Debug\xFileViewer.exe : fatal error LNK1120: 1 unresolved externals

  • Looking Back at MIX10

    - by WeigeltRo
    It’s the sad truth of my life that even though I’m fascinated by airplanes and flight in general since my childhood days, my body doesn’t like flying. Even the ridiculously short flights inside Germany are taking their toll on me each time. Now combine this with sitting in the cramped space of economy class for many hours on a transatlantic flight from Germany to Las Vegas and back, and factor in some heavy dose of jet lag (especially on my way eastwards), and you get an idea why after coming back home I had this question on my mind: Was it really worth it to attend MIX10? This of course is a question that will also be asked by my boss at Comma Soft (for other reasons, obviously), who decided to send me and my colleague Jens Schaller, to the MIX10 conference. (A note to my German readers: An dieser Stelle der Hinweis, dass Comma Soft noch Silverlight-Entwickler und/oder UI-Designer für den Standort Bonn sucht – aussagekräftige Bewerbungen bitte an [email protected]) Too keep things short: My answer is yes. Before I’ll go into detail, let me ask the heretical questions whether tech conferences in general still make sense. There was a time, where actually being at a tech conference gave you a head-start in regard to learning about new technologies. Nowadays this is no longer true, where every bit of information and every detail is immediately twittered, blogged and whatevered to death. In the case of MIX10 you even can download the video-taped sessions shortly after. So: Does visiting a conference still make sense? It depends on what you expect from a conference. It should be clear to everybody that you’ll neither get exclusive information, nor receive training in a small group. What a conference does offer that sitting in front of your computer does not can be summarized as follows: Focus Being away from work and home will help you to focus on the presented information. Of course there are always the poor guys who are haunted by their work (with mails and short text messages reporting the latest showstopper problem), but in general being out of your office makes a huge difference. Inspiration With the focus comes the emotional involvement. I find it much easier to absorb information if I feel that certain vibe when sitting in a session. This still means that I have put work into reviewing the information later, but it’s a better starting point. And all the impressions collected at a (good) conference combined lead to a higher motivation – be it by the buzz (“this is gonna be sooo cool!”) or by the fear to fall behind (“man, we’ll have work on this, or else…”). People At a conference it’s pretty easy to get into contact with other people during breakfast, lunch and other breaks. This is a good opportunity to get a feel for what other development teams are doing (on a very general level of course, nobody will tell you about their secret formula) and what they are thinking about specific technologies. So MIX10 did offer focus, inspiration and people, but that would have meant nothing without valuable content. When I (being a frontend developer with a strong interest in UI/UX) planned my visit to MIX10, I made the decision to focus on the "soft" topics of design, interaction and user experience. I figured that I would be bombarded with all the technical details about Silverlight 4 anyway in the weeks and months to come. Actually, I would have liked to catch a few technical sessions, but the agenda wasn’t exactly in favor of people interested in any kind of Silverlight and UI/UX/Design topics. That’s one of my few complaints about the conference – I would have liked one more day and/or more sessions per day. Overall, the quality of the workshops and sessions was pretty high. In fact, looking back at my collection of conferences I’ve visited in the past I’d say that MIX10 ranks somewhere near the top spot. Here’s an overview of the workshops/sessions I attended (I’ll leave out the keynotes): Day 0 (Workshops on Sunday) Design Fundamentals for Developers Robby Ingebretsen is the man! Great workshop in three parts with the perfect mix of examples, well-structured definition of terminology and the right dose of humor. Robby was part of the WPF team before founding his own company so he not only has a strong interest in design (and the skillz!) but also the technical background.   Design Tools and Techniques Originally announced to be held by Arturo Toledo, the Rosso brothers from ArcheType filled in for the first two parts, and Corrina Black had a pretty general part about the Windows Phone UI. The first two thirds were a mixed bag; the two guys definitely knew what they were talking about, and the demos were great, but the talk lacked the preparation and polish of a truly great presentation. Corrina was not allowed to go into too much detail before the keynote on Monday, but the session was still very interesting as it showed how much thought went into the Windows Phone UI (and there’s always a lot to learn when people talk about their thought process). Day 1 (Monday) Designing Rich Experiences for Data-Centric Applications I wonder whether there was ever a test-run for this session, but what Ken Azuma and Yoshihiro Saito delivered in the first 15 minutes of a 30-minutes-session made me walk out. A commercial for a product (just great: a video showing a SharePoint plug-in in an all-Japanese UI) combined with the most generic blah blah one could imagine. EPIC FAIL.   Great User Experiences: Seamlessly Blending Technology & Design I switched to this session from the one above but I guess I missed the interesting part – what I did catch was what looked like a “look at the cool stuff we did” without being helpful. Or maybe I was just in a bad mood after the other session.   The Art, Technology and Science of Reading This talk by Kevin Larson was very interesting, but was more a presentation of what Microsoft is doing in research (pretty impressive) and in the end lacked a bit the helpful advice one could have hoped for.   10 Ways to Attack a Design Problem and Come Out Winning Robby Ingebretsen again, and again a great mix of theory and practice. The clean and simple, yet effective, UI of the reader app resulted in a simultaneous “wow” of Jens and me. If you’d watch only one session video, this should be it. Microsoft has to bring Robby back next year! Day 2 (Tuesday) Touch in Public: Multi-touch Interaction Design for Kiosks & Architectural Experiences Very interesting session by Jason Brush, a great inspiration with many details to look out for in the examples. Exactly what I was hoping for – and then some!   Designing Bing: Heart and Science How hard can it be to design the UI for a search engine? An input field and a list of results, that should be it, right? Well, not so fast! The talk by Paul Ray showed the many iterations to finally get it right (up to the choice of a specific blue for the links). And yes, I want an eye-tracking device to play around with!   The Elephant in the Room When Nishant Kothary presented a long list of what his session was not about, I told to myself (not having the description text present) “Am I in the wrong talk? Should I leave?”. Boy, was I wrong. A great talk about human factors in the process of designing stuff.   An Hour with Bill Buxton Having seen Bill Buxton’s presentation in the keynote, I just had to see this man again – even though I didn’t know what to expect. Being more or less unplanned and intended to be more of a conversation, the session didn’t provide a wealth of immediately useful information. Nevertheless Bill Buxton was impressive with his huge knowledge of seemingly everything. But this could/should have been a session some when in the evening and not in parallel to at least two other interesting talks. Day 3 (Wednesday) Design the Ordinary, Like the Fixie This session by DL Byron and Kevin Tamura started really well and brought across the message to keep things simple. But towards the end the talk lost some of its steam. And, as a member of the audience pointed out, they kind of ignored their own advice when they used a fancy presentation software other then PowerPoint that sometimes got in the way of showing things.   Developing Natural User Interfaces Speaking of alternative presentation software, Joshua Blake definitely had the most remarkable alternative to PowerPoint, a self-written program called NaturalShow that was controlled using multi-touch on a touch screen. Not a PowerPoint-killer, but impressive nevertheless. The (excellent) talk itself was kind of eye-opening in regard to what “multi-touch support” on various platforms (WPF, Silverlight, Windows Phone) actually means.   Treat your Content Right The talk by Tiffani Jones Brown wasn’t even on my planned schedule, but somehow I ended up in that session – and it was great. And even for people who don’t necessarily have to write content for websites, some points made by Tiffani are valid in many places, notably wherever you put texts with more than a single word into your UI. Creating Effective Info Viz in Microsoft Silverlight The last session of MIX10 I attended was kind of disappointing. At first things were very promising, with Matthias Shapiro giving a brief but well-structured introduction to info graphics and interactive visualizations. Then the live-coding began and while the result was interesting, too much time was spend on wrestling to get the code working. Ending earlier than planned, the talk was a bit light on actual content, but at least it included a nice list of resources. Conclusion It could be felt all across MIX10, UIs will take a huge leap forward; in fact, there are enough examples that have already. People who both have the technical know-how and at least a basic understanding of design (“literacy” as Bill Buxton called it) are in high demand. The concept of the MIX conference and initiatives like design.toolbox shows that Microsoft understands very well that frontend developers have to acquire new knowledge besides knowing how to hack code and putting buttons on a form. There are extremely exciting times before us, with lots of opportunity for those who are eager to develop their skills, that is for sure.
