  • #OOW 2012: Big Data and The Social Revolution

    - by Eric Bezille
    As what was saying Cognizant CSO Malcolm Frank about the "Futur of Work", and how the Business should prepare in the face of the new generation  not only of devices and "internet of things" but also due to their users ("The Millennials"), moving from "consumers" to "prosumers" :  we are at a turning point today which is bringing us to the next IT Architecture Wave. So this is no more just about putting Big Data, Social Networks and Customer Experience (CxM) on top of old existing processes, it is about embracing the next curve, by identifying what processes need to be improve, but also and more importantly what processes are obsolete and need to be get ride of, and new processes put in place. It is about managing both the hierarchical and structured Enterprise and its social connections and influencers inside and outside of the Enterprise. And this does apply everywhere, up to the Utilities and Smart Grids, where it is no more just about delivering (faster) the same old 300 reports that have grown over time with those new technologies but to understand what need to be looked at, in real-time, down to an hand full relevant reports with the KPI relevant to the business. It is about how IT can anticipate the next wave, and is able to answers Business questions, and give those capabilities in real-time right at the hand of the decision makers... This is the turning curve, where IT is really moving from the past decade "Cost Center" to "Value for the Business", as Corporate Stakeholders will be able to touch the value directly at the tip of their fingers. It is all about making Data Driven Strategic decisions, encompassed and enriched by ALL the Data, and connected to customers/prosumers influencers. This brings to stakeholders the ability to make informed decisions on question like : “What would be the best Olympic Gold winner to represent my automotive brand ?”... in a few clicks and in real-time, based on social media analysis (twitter, Facebook, Google+...) and connections link to my Enterprise data. A true example demonstrated by Larry Ellison in real-time during his yesterday’s key notes, where “Hardware and Software Engineered to Work Together” is not only about extreme performances but also solutions that Business can touch thanks to well integrated Customer eXperience Management and Social Networking : bringing the capabilities to IT to move to the IT Architecture Next wave. An example, illustrated also todays in 2 others sessions, that I had the opportunity to attend. The first session bringing the “Internet of Things” in Oil&Gaz into actionable decisions thanks to Complex Event Processing capturing sensors data with the ready to run IT infrastructure leveraging Exalogic for the CEP side, Exadata for the enrich datasets and Exalytics to provide the informed decision interface up to end-user. The second session showing Real Time Decision engine in action for ACCOR hotels, with Eric Wyttynck, VP eCommerce, and his Technical Director Pascal Massenet. I have to close my post here, as I have to go to run our practical hands-on lab, cooked with Olivier Canonge, Christophe Pauliat and Simon Coter, illustrating in practice the Oracle Infrastructure Private Cloud recently announced last Sunday by Larry, and developed through many examples this morning by John Folwer. John also announced today Solaris 11.1 with a range of network innovation and virtualization at the OS level, as well as many optimizations for applications, like for Oracle RAC, with the introduction of the lock manager inside Solaris Kernel. Last but not least, he introduced Xsigo Datacenter Fabric for highly simplified networks and storage virtualization for your Cloud Infrastructure. Hoping you will get ready to jump on the next wave, we are here to help...

  • Access Denied

    - by Tony Davis
    When Microsoft executives wake up in the night screaming, I suspect they are having a nightmare about their own version of Frankenstein's monster. Created with the best of intentions, without thinking too hard of the long-term strategy, and having long outlived its usefulness, the monster still lives on, occasionally wreaking vengeance on the innocent. Its name is Access; a living synthesis of disparate body parts that is resistant to all attempts at a mercy-killing. In 1986, Microsoft had no database products, and needed one for their new OS/2 operating system, the successor to MSDOS. In 1986, they bought exclusive rights to Sybase DataServer, and were also intent on developing a desktop database to capture Ashton-Tate's dominance of that market, with dbase. This project, first called 'Omega' and later 'Cirrus', eventually spawned two products: Visual Basic in 1991 and Access in late 1992. Whereas Visual Basic battled with PowerBuilder for dominance in the client-server market, Access easily won the desktop database battle, with Dbase III and DataEase falling away. Access did an excellent job of abstracting and simplifying the task of building small database applications in a short amount of time, for a small number of departmental users, and often for a transient requirement. There is an excellent front end and forms generator. We not only see it in Access but parts of it also reappear in SSMS. It's good. A business user can pull together useful reports, without relying on extensive technical support. A skilled Access programmer can deliver a fairly sophisticated application, whilst the traditional client-server programmer is still sharpening his pencil. Even for the SQL Server programmer, the forms generator of Access is useful for sketching out application designs. So far, so good, but here's where the problems start; Access ties together two different products and the backend of Access is the bugbear. The limitations of Jet/ACE are well-known and documented. They range from MDB files that are prone to corruption, especially as they grow in size, pathetic security, and "copy and paste" Backups. The biggest problem though, was an infamous lack of scalability. Because Microsoft never realized how long the product would last, they put little energy into improving the beast. Microsoft 'ate their own dog food' by using Access for Microsoft Exchange and Outlook. They choked on it. For years, scalability and performance problems with Exchange Server have been laid at the door of the Jet Blue engine on which it relies. Substantial development work in Exchange 2010 was required, just in order to improve the engine and storage schema so that it more efficiently handled the reading and writing of mails. The alternative of using SQL Server just never panned out. The Jet engine was designed to limit concurrent users to a small number (10-20). When Access applications outgrew this, bitter experience proved that there really is no easy upgrade path from Access to SQL Server, beyond rewriting the whole lot from scratch. The various initiatives to do this never quite bridged the cultural gulf between Access and a true relational database So, what are the obvious alternatives for small, strategic database applications? I know many users who, for simple 'list maintenance' requirements are very happy using Excel databases. Surely, now that PowerPivot has led the way, it is time for Microsoft to offer a new RAD package for database application development; namely an Excel-based front end for SQL Server Express. In that way, we'll have a powerful and familiar front end, to a scalable database, and a clear upgrade path when an app takes off and needs to go enterprise. Cheers, Tony.

  • Social Technology and the Potential for Organic Business Networks

    - by Michael Snow
    Guest Blog Post by:  Michael Fauscette, IDCThere has been a lot of discussion around the topic of social business, or social enterprise, over the last few years. The concept of applying emerging technologies from the social Web, combined with changes in processes and culture, has the potential to provide benefits across the enterprise over a wide range of operations impacting employees, customers, partners and suppliers. Companies are using social tools to build out enterprise social networks that provide, among other things, a people-centric collaborative and knowledge sharing work environment which over time can breakdown organizational silos. On the outside of the business, social technology is adding new ways to support customers, market to prospects and customers, and even support the sales process. We’re also seeing new ways of connecting partners to the business that increases collaboration and innovation. All of the new "connectivity" is, I think, leading businesses to a business model built around the concept of the network or ecosystem instead of the old "stand-by-yourself" approach. So, if you think about businesses as networks in the context of all of the other technical and cultural change factors that we're seeing in the new information economy, you can start to see that there’s a lot of potential for co-innovation and collaboration that was very difficult to arrange before. This networked business model, or what I've started to call “organic business networks,” is the business model of the information economy.The word “organic” could be confusing, but when I use it in this context, I’m thinking it has similar traits to organic computing. Organic computing is a computing system that is self-optimizing, self-healing, self-configuring, and self-protecting. More broadly, organic models are generally patterns and methods found in living systems used as a metaphor for non-living systems.Applying an organic model, organic business networks are networks that represent the interconnectedness of the emerging information business environment. Organic business networks connect people, data/information, content, and IT systems in a flexible, self-optimizing, self-healing, self-configuring, and self-protecting system. People are the primary nodes of the network, but the other nodes — data, content, and applications/systems — are no less important.A business built around the organic business network business model would incorporate the characteristics of a social business, but go beyond the basics—i.e., use social business as the operational paradigm, but also use organic business networks as the mode of operating the business. The two concepts complement each other: social business is the “what,” and the organic business network is the “how.”An organic business network lets the business work go outside of traditional organizational boundaries and become the continuously adapting implementation of an optimized business strategy. Value creation can move to the optimal point in the network, depending on strategic influencers such as the economy, market dynamics, customer behavior, prospect behavior, partner behavior and needs, supply-chain dynamics, predictive business outcomes, etc.An organic business network driven company is the antithesis of a hierarchical, rigid, reactive, process-constrained, and siloed organization. Instead, the business can adapt to changing conditions, leverage assets effectively, and thrive in a hyper-connected, global competitive, information-driven environment.To hear more on this topic – I’ll be presenting in the next webcast of the Oracle Social Business Thought Leader Webcast Series - “Organic Business Networks: Doing Business in a Hyper-Connected World” this coming Thursday, June 21, 2012, 10:00 AM PDT – Register here

  • How does the Trash Can work, and where can I find official documentation, reference, or specification for it?

    - by MestreLion
    When trying to manage trash can from mounted NTFS volumes, I ended up reading FreeDesktop.org's reference on it. Poking around and doing some tests, I realized Ubuntu/Gnome does not follow the specs 100%. Here's why: For non-/ partitions, it always uses <driveroot>/.Trash-<uid>, It never used <driveroot>/.Trash/<uid>, even when i created it in advance. While this works, it's annoying: if I have 15 users, I end up with 15 /.Trash-xxx folders in my drive, while the other approach would still give a single folder (with 15 sub-folders). That "pollution" in my drives is very unpleasant. And specs say "If an $topdir/.Trash directory is absent, an $topdir/.Trash-$uid directory is to be used". Well, it IS present, so why does it never use it? root trash does not work, at least not out of the box. Open nautilus as root and click on trash; it gives an error. Try to delete any file, it says "it can't move to trash". Ok, I know this can be fixed by creating /root/.local/share. But specs says "A “home trash” directory SHOULD be automatically created for any new user. If this directory is needed for a trashing operation but does not exist, the implementation SHOULD automatically create it, without any warnings or delays.". Why the error then? Bug? Why must I change /etc/fstab entries for mounted volumes, adding options like uid and guid, if the volumes are already mounted as RW for everyone? These are just some examples of deviation from the standard. So, the question is: "If Ubuntu does not adhere 100% to the spec, HOW exactly does the trash work? WHERE can i find a technical reference for Ubuntu's implementation of the trash?" By the way: if Ubuntu does happen to follow specs, please tell me what I am doing wrong, especially regarding the /.Trash-<uid> vs /.Trash/<uid> issue. Thanks! EDIT: Some more info: If a given fs has no support for the sticky bit (VFAT, NTFS), it probably doesn't have for permissions either (at least VFAT surely doesn't). So what prevents one user from purging / restoring other users' ./Trash-xxx ? If one can read/write his own Trash, one can do the same for the whole drive, including other's trashes, correct? Or does Gnome have some kind of "extra" protection on ./Trash-xxx folders on VFAT/NTFS fs? If Linux can "emulate" file permissions on NTFS mounting by editing /fstab uid and gid options, can it also "emulate" the sticky bit? I would really prefer to use /.Trash/xxx format... For the root issue: for the / partition, I can use trash as root, and it goes to /root/.local/shate/Trash. But if I click on Nautilus "Trash" (as root), I get an error. Don't you? So files are correctly trashed, but I can't access it. All I can do is manually "purge" them (by deleting files on /root/.local/shate/Trash), but restoring would be very tricky (opening info files and manually moving, etc.). For non-/ partitions (or at least for VFAT/NTFS), I can not even use trash as root: it does not create a ./Trash-0 folder, it simply says "Cannot trash, want to permanently delete?" Why? About fstab: i use it for a permanent mount for my NTFS partitions. I have several, and if not "pre-mounted" they really clutter the desktop and/or Nautilus. I'd rather have it pre-mounted, integrated in my fs, in mounts like /data , /windows/xp , /windows/vista , and so on, and leave /media and its "mount/unmount" flexibility just for truly removable drives. So, if Ubuntu/Gnome truly follows the spec, is there any way to fix the root issues and to "emulate" the sticky bit for (at least) my fstab'ed NTFS fixed partitions?

  • Sneak Peak: Social Developer Program at JavaOne

    - by Mike Stiles
    By guest blogger Roland Smart We're just days away from what is gunning to be the most exciting installment of OpenWorld to date, so how about an exciting sneak peak at the very first Social Developer Program? If your first thought is, "What's a social developer?" you're not alone. It’s an emerging term and one we think will gain prominence as social experiences become more prevalent in enterprise applications. For those who keep an eye on the ever-evolving Facebook platform, you'll recall that they recently rebranded their PDC (preferred developer consultant) group as the PMD (preferred marketing developer), signaling the importance of development resources inside the marketing organization to unlock the potential of social. The marketing developer they're referring to could be considered a social developer in a broader context. While it's true social has really blossomed in the marketing context and CMOs are winning more and more technical resources, social is starting to work its way more deeply into the enterprise with the help of developers that work outside marketing. Developers, like the rest of us, have fallen in "like" with social functionality and are starting to imagine how social can transform enterprise applications in the way it has consumer-facing experiences. The thesis of my presentation is that social developers will take many pages from the marketing playbook as they apply social inside the enterprise. To support this argument, lets walk through a range of enterprise applications and explore how consumer-facing social experiences might be interpreted in this context. Here's one example of how a social experience could be integrated into a sales enablement application. As a marketer, I spend a great deal of time collaborating with my sales colleagues, so I have good insight into their working process. While at Involver, we grew our sales team quickly, and it became evident some of our processes broke with scale. For example, we used to have weekly team meetings at which we'd discuss what was working and what wasn't from a messaging perspective. One aspect of these sessions focused on "objections" and "responses," where the salespeople would walk through common objections to purchasing and share appropriate responses. We tried to map each context to best answers and we'd capture these on a wiki page. As our team grew, however, participation at scale just wasn't tenable, and our wiki pages quickly lost their freshness. Imagine giving salespeople a place where they could submit common objections and responses for their colleagues to see, sort, comment on, and vote on. What you'd get is an up-to-date and relevant repository of information. And, if you supported an application like this with a social graph, it would be possible to make good recommendations to individual sales people about the objections they'd likely hear based on vertical, product, region or other graph data. Taking it even further, you could build in a badging/game element to reward those salespeople who participate the most. Both these examples are based on proven models at work inside consumer-facing applications. If you want to learn about how HR, Operations, Product Development and Customer Support can leverage social experiences, you’re welcome to join us at JavaOne or join our Social Developer Community to find some of the presentations after OpenWorld.

  • Master Data Management for Location Data - Oracle Site Hub

    - by david.butler(at)oracle.com
    Most MDM discussions cover key domains such as customer, supplier, product, service, and reference data. It is usually understood that these domains have complex structures and hundreds if not thousands of attributes that need governing. Location, on the other hand, strikes most people as address data. How hard can that be? But for many industries, locations are complex, and site information is critical to efficient operations and relevant analytics. Retail stores and malls, bank branches, construction sites come to mind. But one of the best industries for illustrating the power of a site mastering application is Oil & Gas.   Oracle's Master Data Management solution for location data is the Oracle Site Hub. It is a location mastering solution that enables organizations to centralize site and location specific information from heterogeneous systems, creating a single view of site information that can be leveraged across all functional departments and analytical systems.   Let's take a look at the location entities the Oracle Site Hub can manage for the Oil & Gas industry: organizations, property, land, buildings, roads, oilfield, service center, inventory site, real estate, facilities, refineries, storage tanks, vendor locations, businesses, assets; project site, area, well, basin, pipelines, critical infrastructure, offshore platform, compressor station, gas station, etc. Any site can be classified into multiple hierarchies, like organizational hierarchy, operational hierarchy, geographic hierarchy, divisional hierarchies and so on. Any site can also be associated to multiple clusters, i.e. collections of sites, and these can be used as a foundation for driving reporting, analysis, organize daily work, etc. Hierarchies can also be used to model entities which are structured or non-structured collections of nodes, like for example routes, pipelines and more. The User Defined Attribute Framework provides the needed infrastructure to add single row attributes groups like well base attributes (well IDs, well type, well structure and key characterizing measures, and more) and well geometry, and multi row attribute groups like well applications, permits, production data, activities, operations, logs, treatments, tests, drills, treatments, and KPIs. Site Hub can also model areas, lands, fields, basins, pools, platforms, eco-zones, and stratigraphic layers as specific sites, tracking their base attributes, aliases, descriptions, subcomponents and more. Midstream entities (pipelines, logistic sites, pump stations) and downstream entities (cylinders, tanks, inventories, meters, partner's sites, routes, facilities, gas stations, and competitor sites) can also be easily modeled, together with their specific attributes and relationships. Site Hub can store any type of unstructured data associated to a site. This could be stored directly or on an external content management solution, like Oracle Universal Content Management. Considering a well, for example, Site Hub can store any relevant associated multimedia file such as: CAD drawings of the well profile, structure and/or parts, engineering documents, contracts, applications, permits, logs, pictures, photos, videos and more. For any site entity, Site Hub can associate all the related assets and equipments at the site, as well as all relationships between sites, between a site and multiple parties, and between a site and any purchasable or sellable item, over time. Items can be equipment, instruments, facilities, services, products, production entities, production facilities (pipelines, batteries, compressor stations, gas plants, meters, separators, etc.), support facilities (rigs, roads, transmission or radio towers, airstrips, etc.), supplier products and services, catalogs, and more. Items can just be associated to sites using standard Site Hub features, or they can be fully mastered by implementing Oracle Product Hub. Site locations (addresses or geographical coordinates) are also managed with out-of-the-box address geo-coding capabilities coupled with Google Maps integration to deliver powerful mapping capabilities and spatial data analysis. Locations can be shared between different sites. Centered on the site location, any site can also have associated areas. Site Hub can master any site location specific information, like for example cadastral, ownership, jurisdictional, geological, seismic and more, and any site-centric area specific information, like for example economical, political, risk, weather, logistic, traffic information and more. Now if anyone ever asks you why locations need MDM, think about how all these Oil & Gas entities and attributes would translate into your business locations. To learn more about Oracle's full MDM solution for the digital oil field, here is a link to Roberto Negro's outstanding whitepaper: Oracle Site Master Data Management for mastering wells and other PPDM entities in a digital oilfield context

  • Analytics in an Omni-Channel World

    - by David Dorf
    Retail has been around ever since mankind started bartering.  The earliest transactions were very specific to the individuals buying and selling, then someone had the bright idea to open a store.  Those transactions were a little more generic, but the store owner still knew his customers and what they wanted.  As the chains rolled out, customer intimacy was sacrificed for scale, and retailers began to rely on segments and clusters.  But thanks to the widespread availability of data and the technology to convert said data into information, retailers are getting back to details. The retail industry is following a maturity model for analytics that is has progressed through five stages, each delivering more value than the previous. Store Analytics Brick-and-mortar retailers (and pure-play catalogers as well) that collect anonymous basket-level data are able to get some sense of demand to help with allocation decisions.  Promotions and foot-traffic can be measured to understand marketing effectiveness and perhaps focus groups can help test ideas.  But decisions are influenced by the majority, using faceless customer segments and aggregated industry data points.  Loyalty programs help a little, but in many cases the cost outweighs the benefits. Web Analytics The Web made it much easier to collect data on specific, yet still anonymous consumers using cookies to track visits. Clickstreams and product searches are analyzed to understand the purchase journey, gauge demand, and better understand up-selling opportunities.  Personalization begins to allow retailers target market consumers with recommendations. Cross-Channel Analytics This phase is a minor one, but where most retailers probably sit today.  They are able to use information from one channel to bolster activities in another. However, there are technical challenges combining data silos so its not an easy task.  But for those retailers that are able to perform analytics on both sources of data, the pay-off is pretty nice.  Revenue per customer begins to go up as customers have a better brand experience. Mobile & Social Analytics Big data technologies are enabling a 360-degree view of the customer by incorporating psychographic data from social sites alongside traditional demographic data.  Retailers can track individual preferences, opinions, hobbies, etc. in order to understand a consumer's motivations.  Using mobile devices, consumers can interact with brands anywhere, anytime, accessing deep product information and reviews.  Mobile, combined with a loyalty program, presents an opportunity to put shopping into geographic context, understanding paths to the store, patterns within the store, and be an always-on advertising conduit. Omni-Channel Analytics All this data along with the proper technology represents a new paradigm in which the clock is turned back and retail becomes very personal once again.  Rich, individualized data better illuminates demand, allows for highly localized assortments, and helps tailor up-selling.  Interactions with all channels help build an accurate profile of each consumer, and allows retailers to tailor the retail experience to meet the heightened expectations of today's sophisticated shopper.  And of course this culminates in greater customer satisfaction and business profitability.

  • What is the SharePoint Action Framework and Why do I need it ?

    - by SAF
    For those out there that are a little curious as to whether SAF is any use to your organisation, please read this FAQ.  What is SAF ? SAF is free to use. SAF is the "SharePoint Action Framework", it was built by myself and Hugo (plus a few others along the way). SAF is written entirely in C# code available from : http://saf.codeplex.com.   SAF is a way to automate SharePoint configuration changes. An Action is a command/class/task/script written in C# that performs a unit of execution against SharePoint such as "CreateWeb"  or "AddLookupColumn". A SAF Macro is collection of one or more Actions. SAF Macro can be run from Msbuild, a Feature, StsAdm or common plain old .Net code. Parameters can be passed to a Macro at run-time from a variety of sources such as "Environment Variable", "*.config", "Msbuild Properties", Feature Properties, command line args, .net code. SAF emits lots of trace statements at run-time, these can be viewed using "DebugView". One Action can pass parameters to another Action. Parameters can be set using Expression Syntax such as "DateTime.Now".  You should consider SAF is you suffer from one of the following symptoms... "Our developers write lots of code to deploy changes at release time - it's always rushed" "I don't want my developers shelling out to Powershell or Stsadm from a Feature". "We have loads of Console applications now, I have lost track of where they are, or what they do" "We seem to be writing similar scripts against SharePoint in lots of ways, testing is hard". "My scripts often have lots of errors - they are done at the last minute". "When something goes wrong - I have no idea what went wrong or how to solve it". "Our Features get stuck and bomb out half way through - there no way to roll them back". "We have tons of Features now - I can't keep track". "We deploy Features to run one-off tasks" "We have a library of reusable scripts, but, we can only run it in one way, sometimes we want to run it from MSbuild and a Feature". "I want to automate the deployment of changes to our development environment". "I would like to run a housekeeping task on a scheduled basis"   So I like the sound of SAF - what's the problems ?  Realistically, there are few things that need to be considered: Someone on your team will need to spend a day or 2 understanding SAF and deciding exactly how you want to use it. I would suggest a Tech Lead, SysAdm or SP Architect will need to download it, try out the examples, look through the unit tests. Ask us questions. Although, SAF can be downloaded and set to go in a few minutes, you will still need to address issues such as - "Do you want to execute your Macros in MsBuild or from a Feature ?" You will need to decide who is going to do your deployments - is it each developer to themself, or do you require a dedicated Build Manager ? As most environments (Dev, QA, Live etc) require different settings (e.g. Urls, Database names, accounts etc), you will more than likely want to define these and set a properties file up for each environment. (These can then be injected into Saf at run-time). There may be no Action to solve your particular problem. If this is the case, suggest it to us - we can try and write it, or write it yourself. It's very easy to write a new Action - we have an approach to easily unit test it, document it and author it. For example, I wrote one to deploy  a WSP in 2 hours the other day. Alternatively, Saf can also call Stsadm commands and Powershell scripts.   Anyway, I do hope this helps! If you still need help, or a quick start, we can also offer consultancy around SAF. If you want to know more give us a call or drop an email to [email protected]

  • DeveloperDeveloperDeveloper! Scotland 2010 - DDDSCOT

    - by Plip
    DDD in Scotland was held on the 8th May 2010 in Glasgow and I was there, not as is uaual at these kind of things as an organiser but actually as a speaker and delegate. The weekend started for me back on Thursday with the arrival of Dave Sussman to my place in Lancashire, after a curry and watching the Electon night TV coverage we retired to our respective beds (yes, I know, I hate to shatter the illusion we both sleep in the same bed wearing matching pijamas is something I've shattered now) ready for the drive up to Glasgow the following afternoon. Before heading up to Glasgow we had to pick up Young Mr Hardy from Wigan then we began the four hour drive back in time... Something that struck me on the journey up is just how beautiful Scotland is. The menacing landscapes bordered with fluffy sheep and whirly-ma-gigs are awe inspiring - well worth driving up if you ever get the chance. Anywho we arrived in Glasgow, got settled intot he hotel and went in search of Speakers for pre conference drinks and food. We discovered a gaggle (I believe that's the collective term) of speakers in the Bar and when we reached critical mass headed off to the Speakers Dinner location. During dinner, SOMEONE set my hair on FIRE. That's all I'm going to say on the matter. Whilst I was enjoying my evening there was something nagging at me, I realised that I should really write my session as I was due to give it the following morning. So after a few more drinks I headed back to the hotel and got some well earned sleep (and washed the fire damage out of my hair). Next day, headed off to the conference which was a lovely stroll through Glasgow City Centre. Non of us got mugged, murdered (or set on fire) arriving safely at the venue, which was a bonus.   I was asked to read out the opening Slides for Barry Carr's session which I did dilligently and with such professionalism that I shocked even myself. At which point I reliased in just over an hour I had to give my presentation, so headed back to the speaker room to finish writing it. Wham, bam and it was all over. Session seemed to go well. I was speaking on Exception Driven Development, which isn't so much a technical solution but rather a mindset around how one should treat exceptions and their code. To be honest, I've not been so nervous giving a session for years - something about this topic worried me, I was concerned I was being too abstract in my thinking or that what I was saying was so obvious that everyone would know it, but it seems to have been well recieved which makes me a happy Speaker. Craig Murphy has some brilliant pictures of DDD Scotland 2010. After my session was done I grabbed some lunch and headed back to the hotel and into town to do some shopping (thus my conspicuous omission from the above photo). Later on we headed out to the geek dinner which again was a rum affair followed by a few drinks and a little boogie woogie. All in all a well run, well attended conference, by the community for the community. I tip my hat to the whole team who put on DDD Scotland!

  • Communication between state machines with hidden transitions

    - by slartibartfast
    The question emerged for me in embedded programming but I think it can be applied to quite a number of general networking situations e.g. when a communication partner fails. Assume we have an application logic (a program) running on a computer and a gadget connected to that computer via e.g. a serial interface like RS232. The gadget has a red/green/blue LED and a button which disables the LED. The LEDs color can be driven by software commands over the serial interface and the state (red/green/blue/off) is read back and causes a reaction in the application logic. Asynchronous behaviour of the application logic with regard to the LED color down to a certain delay (depending on the execution cycle of the application) is tolerated. What we essentially have is a resource (the LED) which can not be reserved and handled atomically by software because the (organic) user can at any time press the button to interfere/break the software attempt to switch the LED color. Stripping this example from its physical outfit I dare to say that we have two communicating state machines A (application logic) and G (gadget) where G executes state changes unbeknownst to A (and also the other way round, but this is not significant in our example) and only A can be modified at a reasonable price. A needs to see the reaction and state of G in one piece of information which may be (slightly) outdated but not inconsistent with respect to the short time window when this information was generated on the side of G. What I am looking for is a concise method to handle such a situation in embedded software (i.e. no layer/framework like CORBA etc. available). A programming technique which is able to map the complete behaviour of both participants on classical interfaces of a classical programming language (C in this case). To complicate matters (or rather, to generalize), a simple high frequency communication cycle of A to G and back (IOW: A is rapidly polling G) is out of focus because of technical restrictions (delay of serial com, A not always active, etc.). What I currently see as a general solution is: the application logic A as one thread of execution an adapter object (proxy) PG (presenting G inside the computer), together with the serial driver as another thread a communication object between the two (A and PG) which is transactionally safe to exchange The two execution contexts (threads) on the computer may be multi-core or just interrupt driven or tasks in an RTOS. The com object contains the following data: suspected state (written by A): effectively a member of the power set of states in G (in our case: red, green, blue, off, red_or_green, red_or_blue, red_or_off...etc.) command data (written by A): test_if_off, switch_to_red, switch_to_green, switch_to_blue operation status (written by PG): operation_pending, success, wrong_state, link_broken new state (written by PG): red, green, blue, off The idea of the com object is that A writes whichever (set of) state it thinks G is in, together with a command. (Example: suspected state="red_or_green", command: "switch_to_blue") Notice that the commands issued by A will not work if the user has switched off the LED and A needs to know this. PG will pick up such a com object and try to send the command to G, receive its answer (or a timeout) and set the operation status and new state accordingly. A will take back the oject once it is no longer at operation_pending and can react to the outcome. The com object could be separated of course (into two objects, one for each direction) but I think it is convenient in nearly all instances to have the command close to the result. I would like to have major flaws pointed out or hear an entirely different view on such a situation.

  • How can I best manage making open source code releases from my company's confidential research code?

    - by DeveloperDon
    My company (let's call them Acme Technology) has a library of approximately one thousand source files that originally came from its Acme Labs research group, incubated in a development group for a couple years, and has more recently been provided to a handful of customers under non-disclosure. Acme is getting ready to release perhaps 75% of the code to the open source community. The other 25% would be released later, but for now, is either not ready for customer use or contains code related to future innovations they need to keep out of the hands of competitors. The code is presently formatted with #ifdefs that permit the same code base to work with the pre-production platforms that will be available to university researchers and a much wider range of commercial customers once it goes to open source, while at the same time being available for experimentation and prototyping and forward compatibility testing with the future platform. Keeping a single code base is considered essential for the economics (and sanity) of my group who would have a tough time maintaining two copies in parallel. Files in our current base look something like this: > // Copyright 2012 (C) Acme Technology, All Rights Reserved. > // Very large, often varied and restrictive copyright license in English and French, > // sometimes also embedded in make files and shell scripts with varied > // comment styles. > > > ... Usual header stuff... > > void initTechnologyLibrary() { > nuiInterface(on); > #ifdef UNDER_RESEARCH > holographicVisualization(on); > #endif > } And we would like to convert them to something like: > // GPL Copyright (C) Acme Technology Labs 2012, Some rights reserved. > // Acme appreciates your interest in its technology, please contact [email protected] > // for technical support, and www.acme.com/emergingTech for updates and RSS feed. > > ... Usual header stuff... > > void initTechnologyLibrary() { > nuiInterface(on); > } Is there a tool, parse library, or popular script that can replace the copyright and strip out not just #ifdefs, but variations like #if defined(UNDER_RESEARCH), etc.? The code is presently in Git and would likely be hosted somewhere that uses Git. Would there be a way to safely link repositories together so we can efficiently reintegrate our improvements with the open source versions? Advice about other pitfalls is welcome.

  • Tyrus 1.8

    - by Pavel Bucek
    Another version of Tyrus, the reference implementation of JSR 356 – Java API for WebSocket is out! Complete list of fixes and features is below, but let me describe some of the new features in more detail. All information presented here is also available in Tyrusdocumentation. What’s new? First to mention is that JSR 356 Maintenance review Ballot is over and the change proposed for 1.1 release was accepted. More details about changes in the API can be found in this article. Important part is that Tyrus 1.8 implements this API, meaning you can use Lambda expressions and some features of Nashorn without the need for any workarounds. Almost all other features are related to client side support, which was significantly improved in this release. Firstly – I have to admit, that Tyrus client contained security issue – SSL Hostname verification was not performed when connecting to “wss” endpoints. This was fixed as part of TYRUS-339 and resulted in some changes in the client configuration API. Now you can control whether HostnameVerification should be performed (SslEngineConfigurator#setHostnameVerificationEnabled(boolean)) or even set your own HostnameVerifier (please use carefully): #setHostnameVerifier(…). Detailed description can be found in Host verification chapter. Another related enhancement is support for Http Basic and Digest authentication schemes. Tyrus client now enables users to provide credentials and underlying implementation will take care of everything else. Our implementation is strictly non pre-emptive, so the login information is sent always as a response to 401 Http Status Code. If the Basic and Digest are not good enough and there is a need to use some custom scheme or something which is not yet supported in Tyrus, custom Authenticator can be registered and the authentication part of the handshake process will be handled by it. Please seeClient HTTP Authentication chapter in the user guide for more details. There are other features, like fine-grain threadpool configuration for JDK client container, build-in Http redirect support and some reshuffling related to unifying the location of client configuration classes and properties definition – every property should be now part of ClientProperties class. All new features are described in the user guide – in chapterTyrus proprietary configuration. Update – Tyrus 1.8.1 There was another slightly late reported issue related to running in environments with SecurityManager enabled, so this version fixes that. Another noteworthy fixes are TYRUS-355 and TYRUS-361; the first one is about incorrect thread factory used for shared container timeout, which resulted in JVM waiting for that thread and not exiting as it should. The other issue enables relative URIs in Location header when using redirect feature. Links Tyrus homepage mailing list JIRA Complete list of changes: Bug [TYRUS-333] – Multiple endpoints on one client [TYRUS-334] – When connection is closed by a peer, periodic heartbeat pong is not stopped [TYRUS-336] – ReaderBuffer.getNextChars() keeps blocking a server thread after client has closed the session [TYRUS-338] – JDK client SSL filter needs better synchronization during handshake phase [TYRUS-339] – SSL hostname verification is missing [TYRUS-340] – Test PathParamTest are not stable with JDK client [TYRUS-341] – A control frame inside a stream of continuation frames is treated as the part of the stream [TYRUS-343] – ControlFrameInDataStreamTest does not pass on GF [TYRUS-345] – NPE is thrown, when shared container timeout property in JDK client is not set [TYRUS-346] – IllegalStateException is thrown, when using proxy in JDK client [TYRUS-347] – Introduce better synchronization in JDK client thread pool [TYRUS-348] – When a client and server close connection simultaneously, JDK client throws NPE [TYRUS-356] – Tyrus cannot determine the connection port for a wss URL [TYRUS-357] – Exception thrown in MessageHandler#OnMessage is not caught in @OnError method [TYRUS-359] – Client based on Java 7 Asynchronous IO makes application unexitable Improvement [TYRUS-328] – JDK 1.7 AIO Client container – threads – (setting threadpool, limits, …) [TYRUS-332] – Consolidate shared client properties into one file.

  • JavaOne Latin America 2012 Trip Report

    - by reza_rahman
    JavaOne Latin America 2012 was held at the Transamerica Expo Center in Sao Paulo, Brazil on December 4-6. The conference was a resounding success with a great vibe, excellent technical content and numerous world class speakers. Some notable local and international speakers included Bruno Souza, Yara Senger, Mattias Karlsson, Vinicius Senger, Heather Vancura, Tori Wieldt, Arun Gupta, Jim Weaver, Stephen Chin, Simon Ritter and Henrik Stahl. Topics covered included the JCP/JUGs, Java SE 7, HTML 5/WebSocket, CDI, Java EE 6, Java EE 7, JSF 2.2, JMS 2, JAX-RS 2, Arquillian and JavaFX. Bruno Borges and I manned the GlassFish booth at the Java Pavilion on Tuesday and Webnesday. The booth traffic was decent and not too hectic. We met a number of GlassFish adopters including perhaps one of the largest GlassFish deployments in Brazil as well as some folks migrating to Java EE from Spring. We invited them to share their stories with us. We also talked with some key members of the local Java community. Tuesday evening we had the GlassFish party at the Tribeca Pub. The party was definitely a hit and we could have used a larger venue (this was the first time we had the GlassFish party in Brazil). Along with GlassFish enthusiasts, a number of Java community leaders were there. We met some of the same folks again at the JUG leader's party on Wednesday evening. On Thursday Arun Gupta, Bruno Borges and I ran a hands-on-lab on JAX-RS, WebSocket and Server-Sent Events (SSE) titled "Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket". This is the same Java EE 7 lab run at JavaOne San Francisco. The lab provides developers a first hand glipse of how an HTML 5 powered Java EE application might look like. We had an overflow crowd for the lab (at one point we had about twenty people standing) and the lab went very well. The slides for the lab are here: Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket from Reza Rahman The actual contents for the lab is available here. Give me a shout if you need help getting it up and running. I gave two solo talks following the lab. The first was on JMS 2 titled "What’s New in Java Message Service 2". This was essentially the same talk given by JMS 2 specification lead Nigel Deakin at JavaOne San Francisco. I talked about the JMS 2 simplified API, JMSContext injection, delivery delays, asynchronous send, JMS resource definition in Java EE 7, standardized configuration for JMS MDBs in EJB 3.2, mandatory JCA pluggability and the like. The session went very well, there was good Q & A and someone even told me this was the best session of the conference! The slides for the talk are here: What’s New in Java Message Service 2 from Reza Rahman My last talk for the conference was on JAX-RS 2 in the keynote hall. Titled "JAX-RS 2: New and Noteworthy in the RESTful Web Services API" this was basically the same talk given by the specification leads Santiago Pericas-Geertsen and Marek Potociar at JavaOne San Francisco. I talked about the JAX-RS 2 client API, asyncronous processing, filters/interceptors, hypermedia support, server-side content negotiation and the like. The talk went very well and I got a few very kind complements afterwards. The slides for the talk are here: JAX-RS 2: New and Noteworthy in the RESTful Web Services API from Reza Rahman On a more personal note, Sao Paulo has always had a special place in my heart as the incubating city for Sepultura and Soulfy -- two of my most favorite heavy metal musical groups of all time! Consequently, the city has a perpertually alive and kicking metal scene pretty much any given day of the week. This time I got to check out a solid performance by local metal gig Republica at the legendary Manifesto Bar. I also wanted to see a Dio Tribute at the Blackmore but ran out of time and energy... Overall I enjoyed the conference/Sao Paulo and look forward to going to Brazil again next year!

  • Book Review: Oracle ADF 11gR2 Development Beginner's Guide

    - by Grant Ronald
    Packt Publishing asked me to review Oracle ADF 11gR2 Development Beginner's Guide by Vinod Krishnan, so on a couple of long flights I managed to get through the book in a couple of sittings. One point to make clear before I go into the review.  Having authored "The Quick Start Guide to Fusion Development: JDeveloper and Oracle ADF", I've written a book which covers the same topic/beginner level.  I also think that its worth stating up front that I applaud anyone who has gone  through the effort of writing a technical book. So well done Vinod.  But on to the review: The book itself is a good break down of topic areas.  Vinod starts with a quick tour around the IDE, which is an important step given all the work you do will be through the IDE.  The book then goes through the general path that I tend to always teach: a quick overview demo, ADF BC, validation, binding, UI, task flows and then the various "add on" topics like security, MDS and advanced topics.  So it covers the right topics in, IMO, the right order.  I also think the writing style flows nicely as well - Its a relatively easy book to read, it doesn't get too formal and the "Have a go hero" hands on sections will be useful for many. That said, I did pick out a number of styles/themes to the writing that I found went against the idea of a beginners guide.  For example, in writing my book, I tried to carefully avoid talking about topics not yet covered or not yet relevant at that point in someone's learning.  So, if I was a new ADF developer reading this book, did I really need to know about ADFBindingFilter and DataBindings.cpx file on page 58 - I've only just learned how to do a drag and drop simple application so showing me XML configuration files relevant to JSF/ADF lifecycle is probably going to scare me off! I found this in a couple of places, for example, the security chapter starts on page 219 but by page 222 (and most of the preceding pages are hands-on steps) we're diving into the web.xml, weblogic.xml, adf-config.xml, jsp-config.xml and jazn-data.xml.  Don't get me wrong, I'm not saying you shouldn't know this, but I feel you have to get people on a strong grounding of the concepts before showing them implementation files.  If having just learned what ADF Security is will "The initialization parameter remove.anonymous.role is set to false for the JpsFilter filter as this filter is the first filter defined in the file" really going to help me? The other theme I found which I felt didn't work was that a couple of the chapters descended into a reference guide.  For example page 159 onwards basically lists UI components and their properties.  And page 87 onwards list the attributes of ADF BC in pretty much the same way as the on line help or developer guide, and I've a personal aversion to any sort of help that says pretty much what the attribute name is e.g. "Precision Rule: this option is used to set a strict precision rule", or "Property Set: this is the property set that has to be applied to the attribute". Hmmm, I think I could have worked that out myself, what I would want to know in a beginners guide are what are these for, what might I use them for...and if I don't need to use them to create an emp/dept example them maybe it’s better to leave them out. All that said, would the book help me - yes it would.  It’s obvious that Vinod knows ADF and his style is relatively easy going and the book covers all that it has to, but I think the book could have done a better job in the educational side of guiding beginners.

  • How does Trash Can works? Where can i find official specification / documentation / reference about it?

    - by MestreLion
    When trying to manage trash can from mounted NTFS volumes, I ended up reading FreeDesktop.org's reference on it. Poking around and doing some tests, I realized Ubuntu/Gnome does not follow the specs 100%. Here's why: For non-/ partitions, it always use <driveroot>/.Trash-<uid>, It never used <driveroot>/.Trash/<uid>, even when i created it in advance. While this works, its annoying: if i have 15 users, i end up with 15 /.Trash-xxx folders in my drive, while the other approach would still give a single folder (with 15 sub-folders). That "pollution" in my drives is very unpleasant. And specs say "If an $topdir/.Trash directory is absent, an $topdir/.Trash-$uid directory is to be used". Well, it IS present, so why it never uses it? root trash does not work, at least not out of the box. Open nautilus as root and click on trash, it gives error. Try to delete any file, it says "it cant move to trash". Ok, i know this can be fixed by creating /root/.local/share. But specs says "A “home trash” directory SHOULD be automatically created for any new user. If this directory is needed for a trashing operation but does not exist, the implementation SHOULD automatically create it, without any warnings or delays.". Why error then? Bug? Why do i must change /etc/fstab entries for mounted volumes, adding options like uid and guid, if the volumes are already mounted as RW for everyone? These are just some examples of deviation from standard. So, the question is: "If Ubuntu does not adhere 100% to the spec, HOW exactly does the trash work? WHERE can i find technical reference about Ubuntu's implementation of the trash?" By the way: if Ubuntu does happen to follow specs, please tell me what am i doing wrong, specially regarding the /.Trash-<uid> vs /.Trash/<uid> issue. Thanks! EDIT: Some more info: If a given fs has no support for sticky bit (VFAT, NTFS), it probably dont have for permitions either (at least VFAT surely doesnt). So what prevents one user for purging / restoring other users ./Trash-xxx ? If one can read/write his own Trash, he can also do the same for the whole drive, including other's trashes, isnt it? Or does Gnome has any "extra" protection on ./Trash-xxx folders on VFAT/NTFS fs? If Linux can "emulate" file permitions on NTFS mounting by editing /fstab uid and gid options, can it also "emulate" the sticky bit? I would really want to use /.Trash/xxx format... For the root issue: for the / partition, i can trash as root, and it goes to /root/.local/shate/Trash. But if i click on Nautilus "Trash" (as root), i get an error. Dont you? So files are correctly trashed, but i cant access it. All i can do is manually "purge" them (by deleting files on /root/.local/shate/Trash), but restoring would be very tricky (opening info files and manually moving, etc) For non-/ partitions (or at least for VFAT/NTFS), I can not even trash as root: it does not create a ./Trash-0 folder, it simply says "Cannot trash, want to permantly delete?" Why? About fstab: i use it for a permanent mount for my NTFS partitions. I have several, and if not "pre-mounted" they really cluttter desktop and/or Nautilus. Id rather have it pre mounted, integrated in my fs, in mounts like /data , /windows/xp , /windows/vista , and so on, and leave /media and its "mount/unmount" flexibility just for truly removable drives Si, if Ubuntu/Gnome truly follow the spec, is there any way to fix the root issues and to "emulate" the sticky bit for (at least) my fstab'ed NTFS fixed partitions?

  • Be the surgeon

    - by Rob Farley
    It’s a phrase I use often, especially when teaching, and I wish I had realised the concept years earlier. (And of course, fits with this month’s T-SQL Tuesday topic, hosted by Argenis Fernandez) When I’m sick enough to go to the doctor, I see a GP. I used to typically see the same guy, but he’s moved on now. However, when he has been able to roughly identify the area of the problem, I get referred to a specialist, sometimes a surgeon. Being a surgeon requires a refined set of skills. It’s why they often don’t like to be called “Doctor”, and prefer the traditional “Mister” (the history is that the doctor used to make the diagnosis, and then hand the patient over to the person who didn’t have a doctorate, but rather was an expert cutter, typically from a background in butchering). But if you ask the surgeon about the pain you have in your leg sometimes, you’ll get told to ask your GP. It’s not that your surgeon isn’t interested – they just don’t know the answer. IT is the same now. That wasn’t something that I really understood when I got out of university. I knew there was a lot to know about IT – I’d just done an honours degree in it. But I also knew that I’d done well in just about all my subjects, and felt like I had a handle on everything. I got into developing, and still felt that having a good level of understanding about every aspect of IT was a good thing. This got me through for the first six or seven years of my career. But then I started to realise that I couldn’t compete. I’d moved into management, and was spending my days running projects, rather than writing code. The kids were getting older. I’d had a bad back injury (ask anyone with chronic pain how it affects  your ability to concentrate, retain information, etc). But most of all, IT was getting larger. I knew kids without lives who knew more than I did. And I felt like I could easily identify people who were better than me in whatever area I could think of. Except writing queries (this was before I discovered technical communities, and people like Paul White and Dave Ballantyne). And so I figured I’d specialise. I wish I’d done it years earlier. Now, I can tell you plenty of people who are better than me at any area you can pick. But there are also more people who might consider listing me in some of their lists too. If I’d stayed the GP, I’d be stuck in management, and finding that there were better managers than me too. If you’re reading this, SQL could well be your thing. But it might not be either. Your thing might not even be in IT. Find out, and then see if you can be a world-beater at it. But it gets even better, because you can find other people to complement the things that you’re not so good at. My company, LobsterPot Solutions, has six people in it at the moment. I’ve hand-picked those six people, along with the one who quit. The great thing about it is that I’ve been able to pick people who don’t necessarily specialise in the same way as me. I don’t write their T-SQL for them – generally they’re good enough at that themselves. But I’m on-hand if needed. Consider Roger Noble, for example. He’s doing stuff in HTML5 and jQuery that I could never dream of doing to create an amazing HTML5 version of PivotViewer. Or Ashley Sewell, a guy who does project management far better than I do. I could go on. My team is brilliant, and I love them to bits. We’re all surgeons, and when we work together, I like to think we’re pretty good! @rob_farley

  • Is This Your Idea of Disaster Recovery?

    - by rickramsey
    Don't just make do with less. Protect what you've got. By, for instance, deploying Oracle Solaris 10 inside a zone cluster. "Wait," you say, "what is a zone cluster?" It is a zone deployed across different physical servers. "Who would do that!" you ask in a mild panic. Why, an upstanding sysadmin citizen interested in protecting his or her employer's investment with appropriate high availability and disaster recovery. If one server gets wiped out by Hurricane Sandy along with pretty much the entire East Coast of the USA, your zone continues to run on the other server(s). Provided you set them up in Edinburgh. This white paper (pdf) explains what a zone cluster is and how to use it. If a white paper reminds you of having to read War and Peace in school, just use this Oracle RAC and Solaris Cluster Cheat Sheet, instead. "But wait!" you exclaim. "I didn't realize Solaris 10 offered zone clusters!" I didn't, either! And in an earlier version of this blog post I said that zone clusters were only available with Oracle Solaris 11. But Karoly Vegh pointed me to the documentation for Oracle Solaris Cluster 3.3, which explains how to manage zone clusters in Oracle Solaris 10. Bite my fist! So, the point I was trying to make is not just that you can run Oracle Solaris 10 zone clusters, but that you can run them in an Oracle Solaris 11 environment. Now let's return to our conversation and pick up where we left off ... "Oh no! Whatever shall I do?" Fear not. Remember how Oracle Solaris 11 lets you create a Solaris 10 branded zone inside a system running Oracle Solaris 11? Well, the Solaris Cluster engineers thought that was a bang-up idea, and decided to extend Oracle Solaris Cluster so that you could run your Solaris 10 applications inside the protective cocoon of an Oracle Solaris 11 zone cluster. Take advantage of the installation improvements and network virtualization capabilities of Oracle Solaris 11 while still running your application on Oracle Solaris 10. You Luddite, you. That capability is in the latest release of Oracle Solaris Cluster, version 4.1, which became available last Friday. "Last Friday! Is it too late to get a copy?" You can still get a free copy from our download center (see below). And, if you'd like to know what other goodies the 4.1 release of Oracle Solaris Cluster provides, see: What's New In Oracle Solaris Cluster 4.1 (pdf) Free download Oracle Solaris Cluster 4.1 (SPARC or x86) Tech Article: How to Upgrade to Oracle Solaris Cluster 4.0, by Tim Read. As always, you can get the latest information about Oracle Solaris Cluster, plus technical how-to articles, documentation, and more from Oracle Solaris Cluster Resource Page for Sysadmins and Developers. And don't forget about the online launch of Oracle Solaris 11.1 and Oracle Solaris Cluster 4.1, scheduled for Nov 7. "I feel so much better, now!" Think nothing of it. That's what we're here for. - Rick Website Newsletter Facebook Twitter

  • 5 Ways to Celebrate the Release of Internet Explorer 9

    - by David Wesst
    The day has finally come: Microsoft has released a web browser that is awesome. On Monday night, Microsoft officially introduced the world to the latest edition to its product family: Internet Explorer 9. That makes March 14, 2011 (also known as PI day) the official birthday of Microsoft’s rebirth in the world of web browsing. Just like any big event, you take some time to celebrate. Here are a few things that you can do to celebrate the return of Internet Explorer. 1. Download It If you’re not a big partier, that’s fine. The one thing you can do (and definitely should) is download it and give it a shot. Sure, IE may have disappointed you in the past, but believe me when I say they really put the effort in this time. The absolute least you can do is give it a shot to see how it stands up against your favourite browser. 2. Get yourself an HTML5 Shirt One of the coolest, if not best parts of IE9 being released is that it officially introduces HTML5 as a fully supported platform from Microsoft. IE9 supports a lot of what is already defined in the HTML5 technical spec, which really demonstrates Microsoft’s support of the new standard. Since HTML5 is cool on the web, it means that it is cool to wear it too. Head over to html5shirt.com and get yourself, or your staff, or your whole family, an HTML5 shirt to show the real world that you are ready for the future of the web. 3. HTML5-ify Something Okay, so maybe a shirt isn’t enough for you. Maybe you need start using HTML5 for real. If you have a blog, or a website, or anything out there on the web, celebrate IE9 adding some HTML5 to your site. Whether that is updating old code, adding something new, or just changing your WordPress theme, definitely take a look at what HTML5 can do for you. 4. Help Kill Old IE and Upgrade your Organization See this? This is sad. Upgrading web browsers in an large enterprise or organization is not a trivial task. A lot of companies will use the excuse of not having the resources to upgrade legacy web applications they were built for a specific version of IE and it doesn’t render correctly in legacy browsers. Well, it’s time to stop the excuses. IE9 allows you to define what version of Internet Explorer you would like it to emulate. It takes minimal effort for the developer, and will get rid of the excuses. Show your IT manager or software development team this link and show them how easy it is to make old code render right in the latest and greatest from the IE team. 5. Submit an Entry for DevUnplugged So, you’ve made it to number five eh? Well then, you must be pretty hardcore to make it this far down the list. Fine, let’s take it to the next level and build an HTML5 game. That’s right. A game. Like a video game. HTML5 introduces some amazing new features that can let you build working video games using HTML5, CSS3, and JavaScript. Plus, Microsoft is celebrating the launch of IE9 with a contest where you can submit an HTML5 game (or audio application) and have a chance to win a whack of cash and other prizes. Head here for the full scoop and rules for the DevUnplugged. This post also appears at http://david.wes.st

  • Abstraction, Politics, and Software Architecture

    Abstraction can be defined as a general concept and/or idea that lack any concrete details. Throughout history this type of thinking has led to an array of new ideas and innovations as well as increased confusion and conspiracy. If one was to look back at our history they will see that abstraction has been used in various forms throughout our past. When I was growing up I do not know how many times I heard politicians say “Leave no child left behind” or “No child left behind” as a major part of their campaign rhetoric in regards to a stance on education. As you can see their slogan is a perfect example of abstraction because it only offers a very general concept about improving our education system but they do not mention how they would like to do it. If they did then they would be adding concrete details to their abstraction thus turning it in to an actual working plan as to how we as a society can help children succeed in school and in life, but then they would not be using abstraction. By now I sure you are thinking what does abstraction have to do with software architecture. You are valid in thinking this way, but abstraction is a wonderful tool used in information technology especially in the world of software architecture. Abstraction is one method of extracting the concepts of an idea so that it can be understood and discussed by others of varying technical abilities and backgrounds. One ways in which I tend to extract my architectural design thoughts is through the use of basic diagrams to convey an idea for a system or a new feature for an existing application. This allows me to generically model an architectural design through the use of views and Unified Markup Language (UML). UML is a standard method for creating a 4+1 Architectural View Models. The 4+1 Architectural View Model consists of 4 views typically created with UML as well as a general description of the concept that is being expressed by a model. The 4+1 Architectural View Model: Logical View: Models a system’s end-user functionality. Development View: Models a system as a collection of components and connectors to illustrate how it is intended to be developed.  Process View: Models the interaction between system components and connectors as to indicate the activities of a system. Physical View: Models the placement of the collection of components and connectors of a system within a physical environment. Recently I had to use the concept of abstraction to express an idea for implementing a new security framework on an existing website. My concept would add session based management in order to properly secure and allow page access based on valid user credentials and last user activity.  I created a basic Process View by using UML diagrams to communicate the basic process flow of my changes in the application so that all of the projects stakeholders would be able to understand my idea. Additionally I created a Logical View on a whiteboard while conveying the process workflow with a few stakeholders to show how end-user will be affected by the new framework and gaining additional input about the design. After my Logical and Process Views were accepted I then started on creating a more detailed Development View in order to map how the system will be built based on the concept of components and connections based on the previously defined interactions. I really did not need to create a Physical view for this idea because we were updating an existing system that was already deployed based on an existing Physical View. What do you think about the use of abstraction in the development of software architecture? Please let me know.
