  • Seizing the Moment with Mobility

    - by Kathryn Perry
    A guest post by Hernan Capdevila, Vice President, Oracle Fusion Apps Mobile devices are forcing a paradigm shift in the workplace – they’re changing the way businesses can do business and the type of cultures they can nurture. As our customers talk about their mobile needs, we hear them saying they want instant-on access to enterprise data so workers can be more effective at their jobs anywhere, anytime. They also are interested in being more cost effective from an IT point of view. The mobile revolution – with the idea of BYOD (bring your own device) – has added an interesting dynamic because previously IT was driving the employee device strategy and ecosystem. That's been turned on its head with the consumerization of IT. Now employees are figuring out how to use their personal devices for work purposes and IT has to figure out how to adapt. Blurring the Lines between Work and Personal Life My vision of where businesses will be five years from now is that our work lives and personal lives will be more interwoven together. In turn, enterprises will have to determine how to make employees’ work lives fit more into the fabric of their personal lives. And personal devices like smartphones are going to drive significant business value because they let us accomplish things very incrementally. I can be sitting on a train or in a taxi and be productive. At the end of any meeting, I can capture ideas and tasks or follow up with people in real time. Mobile devices enable this notion of seizing the moment – capitalizing on opportunities that might otherwise have slipped away because we're not connected. For the industry shapers out there, this is game changing. The lean and agile workforce is definitely the future. This notion of the board sitting down with the executive team to lay out strategic objectives for a three- to five-year plan, bringing in HR to determine how they're going to staff the strategic activities, kicking off the execution, and then revisiting the plan in three to five years to create another three- to five-year plan is yesterday's model. Businesses that continue to approach innovating in that way are in the dinosaur age. Today it's about incremental planning and incremental execution, which requires a lot of cohesion and synthesis within the workforce. There needs to be this interweaving notion within the workforce about how ideas cascade down, how people engage, how they stay connected, and how insights are shared. How to Survive and Thrive in Today’s Marketplace The notion of Facebook isn’t new. We lived it pre-Internet days with America Online and Prodigy – Facebook is just the renaissance of these services in a more viral and pervasive way. And given the trajectory of the consumerization of IT with people bringing their personal tooling to work, the enterprise has no option but to adapt. The sooner that businesses realize this from a top-down point of view the sooner that they will be able to really drive significant innovation and adapt to the marketplace. There are a small number of companies right now (I think it's closer to 20% rather than 80%, but the number is expanding) that are able to really innovate in this incremental marketplace. So from a competitive point of view, there's no choice but to be social and stay connected. By far the majority of users on Facebook and LinkedIn are mobile users – people on iPhones, smartphones, Android phones, and tablets. It's not the couch people, right? It's the on-the-go people – those people at the coffee shops. Usually when you're sitting at your desk on a big desktop computer, typically you have better things to do than to be on Facebook. This is a topic I'm extremely passionate about because I think mobile devices are game changing. Mobility delivers significant value to businesses – it also brings dramatic simplification from a functional point of view and transforms our work life experience.

  • Oracle Social Network Developer Challenge: Fishbowl Solutions

    - by Kellsey Ruppel
    Originally posted by Jake Kuramoto on The Apps Lab blog. Today, I give you the final entry in the Oracle Social Network Developer Challenge, held last week during OpenWorld. This one comes from Friend of the ‘Lab and Fishbowl Solutions (@fishbowle20) hacker, John Sim (@jrsim_uix), whom you might remember from his XBox Kinect demo at COLLABORATE 12 (presentation slides and abstract) hacks and other exploits with WebCenter. We put this challenge together specifically for developers like John, who like to experiment with new tools and push the envelope of what’s possible and build cool things, and as you can see from his entry John did just that, mashing together Google Maps and Oracle Social Network into a mobile app built with PhoneGap that uses the device’s camera and GPS to keep teams on the move in touch. He calls it a Mobile GeoTagging Solution, but I think Avengers Assemble! would have equally descriptive, given that was obviously his inspiration. Here’s his description of the mobile app: My proposed solution was to design and simplify GeoLocation mapping, and automate updates for users and teams on the move; who don’t have access to a laptop or want to take their ipads out – but allow them to make quick updates to OSN and upload photos taken from their mobile device – there and then. As part of this; the plan was to include a rules engine that could be configured by the user to allow the device to automatically update and post messages when they arrived at a set location(s). Inspiration for this came from on{x} – automate your life. Unfortunately, John didn’t make it to the conference to show off his hard work in person, but luckily, he had a colleague from Fishbowl and a video to showcase his work.    Here are some shots of John’s mobile app for your viewing pleasure: John’s thinking is sound. Geolocation is usually relegated to consumer use cases, thanks to services like foursquare, but distributed teams working on projects out in the world definitely need a way to stay in contact. Consider a construction job. Different contractors all converge on a single location, and time is money. Rather than calling or texting each other and risking a distracted driving accident, an app like John’s allows everyone on the job to see exactly where the other contractors are. Using his GPS rules, they could easily be notified about how close each is to the site, definitely useful when you have a flooring contractor sitting idle, waiting for an electrician to finish the wiring. The best part is that the project manager or general contractor could stay updated on all the action (or inaction) using Oracle Social Network, either sitting at a desk using the browser app or desktop client or on the go, using one of the native mobile apps built for Oracle Social Network. I can see this being used by insurance adjusters too, and really any team that, erm, assembles at a given spot. Of course, it’s also useful for meeting at the pub after the day’s work is done. Beyond people, this solution could also be implemented for physical objects that are in route to a destination. Say you’re a customer waiting on rail shipment or a package delivery. You could track your valuable’s whereabouts easily as they report their progress via checkins. If they deviated from the GPS rules, you’d be notified. You might even be able to get a picture into Oracle Social Network with some light hacking. Thanks to John and his colleagues at Fishbowl for participating in our challenge. We hope everyone had a good experience. Make sure to check out John’s blog post on his work and the experience using Oracle Social Network. Although this is the final, official entry we had, tomorrow, I’ll show you the work of someone who finished code, but wasn’t able to make the judging event. Stay tuned.

  • New college grad, psychology major, wants to code professionally. Should I get Sun Java-certified?

    - by Anita
    I just graduated from a fairly well-known liberal arts college in May. Interestingly, I majored in psychology, with a concentration in social psychology. In college I took Intro to Computer Science and hated it (used to blame it on myself; now I blame it on the professor :) However, I've always wanted to be a programmer, and finally got my wish by getting hired by a company that was willing to let me learn coding from scratch in exchange for low pay. Well, what do you know, I just got laid off this morning, and need a new job by November to pay the bills. I loved the coding part of my job at the company, and managed to learn enough Java to feel competent in the job and curious to learn more. I think my goal now is to become a professional programmer. I still know very little (never used Swing, for example) but nothing that a good book can't fix. That's the background anyway; sorry for the rambling - I'm still in shock from the layoff :( It seems to me the quickest way to get noticed by companies, without a CS degree, is by getting certification. I'm halfway through studying for the SCJP and can probably sit for an exam in a week or two. Am I right in my assumption that certs will help in my case? And in general, do I have a bat's chance in hell of making it against formally trained programmers? My assets are really just raw intelligence and intense curiosity; well, maybe a love for problem-solving too. Thanks all - feel free to edit/tag the post!

  • How Easy is it to Code In-Built Videos?

    - by Alan Parker
    First time poster so please don't bite my head off. Basically, I'm having a site built for me and I don't really know anything about coding but I'm not too sure if I trust my web developer. I asked him recently about adding a feature where I could display built-in videos like the following page - http://www.ejot.co.uk/buildingfasteners.odl and he quoted me quite a high amount for it. I just wanted to double check with you guys whether this is a difficult feature to add in and whether it justifies a reasonable amount of money on top of what I'm already paying him. Thanks in advance for your help, Alan

  • What is the best way to code the XNA Game Server for FPS game?

    - by AgentFire
    I'm writing a FPS XNA game. It gonna be multiplayer so I came up with following: I'm making two different assemblies — one for the game logic and the second for drawing it and the game irrelevant stuff (like rocket trails). The type of the connection is client-server (not peer-to-peer), so every client at first connects to the server and then the game begins. I'm completly decided to use XNA.Framework.Game class for the clients to run their game in window (or fullscreen) and the GameComponent/DrawableGameComponent classes to store the game objects and update&draw them on each frame. Next, I want to get the answer to the question: What should I do on the server side? I got few options: Create my own Game class on the server, which will process all the game logic (only, no graphics). The reason why I am not using the standart Game class is when I call Game.Run() the white window appears and I cant figure out how to get rid of it. Use somehow the original XNA's Game class, which is already has the GameComponent collection and Update event (60 times per second, just what I need). UPDATE: I got more questions: First, what socket mode should I use? TCP or UDP? And how to actually let the client know that this packet is meant to be processed after that one? Second, if I is going to use exacly GameComponent class for the game objects which is stored and process on the server, how to make them to be drawn on the client? Inherit them (while they are combined to an assembly)? Something else?

  • Override an IOCTL Handler in PQOAL

    - by Kate Moss' Big Fan
    When porting or creating a BSP to a new platform, we often need to make change to OEMIoControl or HAL IOCTL handler for more specific. Since Microsoft introduced PQOAL in CE 5.0 and more and more BSP today leverages PQOAL to simplify the OAL, we no longer define the OEMIoControl directly. It is somehow analogous to migrate from pure Windows SDK to MFC; people starts to define those MFC handlers and forgot the WinMain and the big message loop. If you ever take a look at the interface between OAL and Kernel, PUBLIC\COMMON\OAK\INC\oemglobal.h, the pfnOEMIoctl is still there just as the entry point of Windows Program is WinMain since day one. (For those may argue about pfnOEMIoctl is not OEMIoControl, I will encourage you to dig into PRIVATE\WINCEOS\COREOS\NK\OEMMAIN\oemglobal.c which initialized pfnOEMIoctl to OEMIoControl. The interface is just to split OAL and Kernel which no longer linked to one executable file in CE 6, all of the function signature is still identical) So let's trace into PQOAL to realize how it implements OEMIoControl and how can we override an IOCTL handler we interest. First thing to know is the entry point (just as finding the WinMain in MFC), OEMIoControl is defined in PLATFORM\COMMON\SRC\COMMON\IOCTL\ioctl.c. Basically, it does nothing special but scan a pre-defined IOCTL table, g_oalIoCtlTable, and then execute the handler. (The highlight part) Other than that is just for error handling and the use of critical section to serialize the function. BOOL OEMIoControl(     DWORD code, VOID *pInBuffer, DWORD inSize, VOID *pOutBuffer, DWORD outSize,     DWORD *pOutSize ) {     BOOL rc = FALSE;     UINT32 i; ...     // Search the IOCTL table for the requested code.     for (i = 0; g_oalIoCtlTable[i].pfnHandler != NULL; i++) {         if (g_oalIoCtlTable[i].code == code) break;     }     // Indicate unsupported code     if (g_oalIoCtlTable[i].pfnHandler == NULL) {         NKSetLastError(ERROR_NOT_SUPPORTED);         OALMSG(OAL_IOCTL, (             L"OEMIoControl: Unsupported Code 0x%x - device 0x%04x func %d\r\n",             code, code >> 16, (code >> 2)&0x0FFF         ));         goto cleanUp;     }            // Take critical section if required (after postinit & no flag)     if (         g_ioctlState.postInit &&         (g_oalIoCtlTable[i].flags & OAL_IOCTL_FLAG_NOCS) == 0     ) {         // Take critical section                    EnterCriticalSection(&g_ioctlState.cs);     }     // Execute the handler     rc = g_oalIoCtlTable[i].pfnHandler(         code, pInBuffer, inSize, pOutBuffer, outSize, pOutSize     );     // Release critical section if it was taken above     if (         g_ioctlState.postInit &&         (g_oalIoCtlTable[i].flags & OAL_IOCTL_FLAG_NOCS) == 0     ) {         // Release critical section                    LeaveCriticalSection(&g_ioctlState.cs);     } cleanUp:     OALMSG(OAL_IOCTL&&OAL_FUNC, (L"-OEMIoControl(rc = %d)\r\n", rc ));     return rc; }   Where is the g_oalIoCtlTable? It is defined in your BSP. Let's use DeviceEmulator BSP as an example. The PLATFORM\DEVICEEMULATOR\SRC\OAL\OALLIB\ioctl.c defines the table as const OAL_IOCTL_HANDLER g_oalIoCtlTable[] = { #include "ioctl_tab.h" }; And that leads to PLATFORM\DEVICEEMULATOR\SRC\INC\ioctl_tab.h which defined some of IOCTL handler but others are defined in oal_ioctl_tab.h which is under PLATFORM\COMMON\SRC\INC\. Finally, we got the full table body! (Just like tracing MFC, always jumping back and forth). The format of table is very straight forward, IOCTL code, Flags and Handler Function // IOCTL CODE,                          Flags   Handler Function //------------------------------------------------------------------------------ { IOCTL_HAL_INITREGISTRY,                   0,  OALIoCtlHalInitRegistry     }, { IOCTL_HAL_INIT_RTC,                       0,  OALIoCtlHalInitRTC          }, { IOCTL_HAL_REBOOT,                         0,  OALIoCtlHalReboot           }, The PQOAL scans through the table until it find a matched IOCTL code, then invokes the handler function. Since it scans the table from the top which means if we define TWO handler with same IOCTL code, the first one is always invoked with no exception. Now back to the PLATFORM\DEVICEEMULATOR\SRC\INC\ioctl_tab.h, with the following table { IOCTL_HAL_INITREGISTRY,                   0,  OALIoCtlDeviceEmulatorHalInitRegistry     }, ... #include <oal_ioctl_tab.h> Note the IOCTL_HAL_INITREGISTRY handler are defined in both BSP's local ioctl_tab.h and the common oal_ioctl_tab.h, but due to BSP's local handler comes before "#include <oal_ioctl_tab.h>" so we know the OALIoCtlDeviceEmulatorHalInitRegistry always get called. In this example, the DeviceEmulator BSP overrides the IOCTL_HAL_INITREGISTRY handler from OALIoCtlHalInitRegistry to OALIoCtlDeviceEmulatorHalInitRegistry by manipulating the g_oalIoCtlTable table. (In some point of view, it is similar to message map in MFC) Please be aware, when you override an IOCTL handler in PQOAL, you may want to clone the original implementation to your BSP and change to meet your need. It is recommended and save you the redundant works but remember to rename the handler function (Just like the DeviceEmulator it changes the name of OALIoCtlHalInitRegistry to OALIoCtlDeviceEmulatorHalInitRegistry). If you don't change the name, linker may not be happy (due to name conflict) and the more important is by using different handler name, you could always redirect the handler back to original one. (It is like the concept of OOP that calling a function in base class; still not so clear? I am goinf to show you soon!) The OALIoCtlDeviceEmulatorHalInitRegistry setups DeviceEmulator specific registry settings and in the end, if everything goes well, it calls the OALIoCtlHalInitRegistry (PLATFORM\COMMON\SRC\COMMON\IOCTL\reginit.c) to do the rest.     if(fOk) {         fOk = OALIoCtlHalInitRegistry(code, pInpBuffer, inpSize, pOutBuffer,             outSize, pOutSize);     } Now you got the picture, whenever you want to override an IOCTL hadnler that is implemented in PQOAL just Clone the handler function to your BSP as a template. Simple name change for the handler function, and a name change in the IOCTL table header file that maps the IOCTL with the function Implement your IOCTL handler and whenever you need to redirect it back just calling the original handler function. It is the standard way of implementing a custom IOCTL and most Microsoft developers prefer. The mapping of IOCTL routine to IOCTL code is platform specific - you control the header file that does that mapping.

  • Why are many programmers moving their code to github?

    - by Chibueze Opata
    For the past 6 months or more, I've been seeing many codes hosted at sourceforge.net as well as other hosting sites "Move to GitHub". A mere Google Search with the phrase "Moved to Github" returns several results containing the text moved to github. This is very confusing for me, and I'm wondering, why exactly are people moving? Does it mean that GitHub is better or is there some special advantage I'm not seeing?

  • How does the GPL static vs. dynamic linking rule apply to interpreted languages?

    - by ekolis
    In my understanding, the GPL prohibits static linking from non-GPL code to GPL code, but permits dynamic linking from non-GPL code to GPL code. So which is it when the code in question is not linked at all because the code is written in an interpreted language (e.g. Perl)? It would seem to be too easy to exploit the rule if it was considered dynamic linking, but on the other hand, it would also seem to be impossible to legally reference GPL code from non-GPL code if it was considered static! Compiled languages at least have a distinction between static and dynamic linking, but when all "linking" is just running scripts, it's impossible to tell what the intent is without an explicit license! Or is my understanding of this issue incorrect, rendering the question moot? I've also heard of a "classpath exception" which involves dynamic linking; is that not part of the GPL but instead something that can be added on to it, so dynamic linking is only allowed when the license includes this exception?

  • Has any hobbyist attempted to make a simple VGA-graphics based operating system in machine code?

    - by Bigyellow Bastion
    I mean real bare bones, bare machine here(no Linux kernel, pre-existing kernel, or any bootloader). I mean honestly write the bootloading software in direct microarchitecture-specific machine opcode, host the operating system, interrupts, I/O, services, and graphical software and all hardware interaction, computation, and design entirely in binary. I know this is quite the leap here, but I was thinking to practice first in x86 assembly (not binary) 16-bit style. Any ideas?

  • Where to find clients who are willing to pay top dollar for highly reliable code?

    - by Robin Green
    I'm looking to find clients who are willing to pay a premium above usual contractor rates, for software that is developed with advanced tools and techniques to eliminate certain classes of bugs. However, I have little experience of contracting, and relatively few contacts. It's important to state that the kind of tools and techniques I'm thinking of (e.g. formal verification) are used commercially extremely rarely, as far as I'm aware. There is kind of a continuum of approaches to higher reliability, with basic testing and basic static typing at one end and full-blown formal verification at the other, but the methods I'm thinking of are towards the latter end of the spectrum.

  • JustCode Provides Reflector Alternative

    - by Joe Mayo
    If you've been a loyal Reflector user, you've probably been exposed to the debacle surrounding RedGate's decision to no longer offer a free version.  Since then, the race has begun for a replacement with a provider that would stand by their promises to the community.  Mono has an ongoing free alternative, which has been available for a long time.  However, other vendors are stepping up to the plate, with their own offerings. If Not Reflector, Then What? One of these vendors is Telerik.  In their recent Q1 2011 release of JustCode, Telerik offers a decompilation utility rivaling what we've become accustomed to in Reflector.  Not only does Telerik offer a usable replacement, but they've (in my opinion), produced a product that integrates more naturally with visual Studio than any other product ever has.  Telerik's decompilation process is so easy that the accompanying demo in this post is blindingly short (except for the presence of verbose narrative). If you want to follow along with this demo, you'll need to have Telerik JustCode installed.  If you don't have JustCode yet, you can buy it or download a trial at the Telerik Web site . A Tall Tale; Prove It! With JustCode, you can view code in the .NET Framework or any other 3rd party library (that isn't well obfuscated).  This demo depends on LINQ to Twitter, which you can download from CodePlex.com and create a reference or install the package online as described in my previous post on NuGet.  Regardless of the method, you'll have a project with a reference to LINQ to Twitter.  Use a Console Project if you want to follow along with this demo. Note:  If you've created a Console project, remember to ensure that the Target Framework is set to .NET Framework 4.  The default is .NET Framework 4 Client Profile, which doesn't work with LINQ to Twitter.  You can check by double-clicking the Properties folder on the project and inspecting the Target Framework setting. Next, you'll need to add some code to your program that you want to inspect. Here, I add code to instantiate a TwitterContext, which is like a LINQ to SQL DataContext, but works with Twitter: var l2tCtx = new TwitterContext(); If you're following along add the code above to the Main method, which will look similar to this: using LinqToTwitter; namespace NuGetInstall { class Program { static void Main(string[] args) { var l2tCtx = new TwitterContext(); } } } The code above doesn't really do anything, but it does give something that I can show and demonstrate how JustCode decompilation works. Once the code is in place, click on TwitterContext and press the F12 (Go to Definition) key.  As expected, Visual Studio opens a metadata file with prototypes for the TwitterContext class.  Here's the result: Opening a metadata file is the normal way that Visual Studio works when navigating to the definition of a type where you don't have the code.  The scenario with TwitterContext happens because you don't have the source code to the file.  Visual Studio has always done this and you can experiment by selecting any .NET type, i.e. a string type, and observing that Visual Studio opens a metadata file for the .NET String type. The point I'm making here is that JustCode works the way Visual Studio works and you'll see how this can make your job easier. In the previous figure, you only saw prototypes associated with the code. i.e. Notice that the default constructor is empty.  Again, this is normal because Visual Studio doesn't have the ability to decompile code.  However, that's the purpose of this post; showing you how JustCode fills that gap. To decompile code, right click on TwitterContext in the metadata file and select JustCode Navigate -> Decompile from the context menu.  The shortcut keys are Ctrl+1.  After a brief pause, accompanied by a progress window, you'll see the metadata expand into full decompiled code. Notice below how the default constructor now has code as opposed to the empty member prototype in the original metadata: And Why is This So Different? Again, the big deal is that Telerik JustCode decompilation works in harmony with the way that Visual Studio works.  The navigate to functionality already exists and you can use that, along with a simple context menu option (or shortcut key) to transform prototypes into decompiled code. Telerik is filling the the Reflector/Red Gate gap by providing a supported alternative to decompiling code.  Many people, including myself, used Reflector to decompile code when we were stuck with buggy libraries or insufficient documentation.  Now we have an alternative that's officially supported by a company with an excellent track record for customer (developer) service, Telerik.  Not only that, JustCode has several other IDE productivity tools that make the deal even sweeter.

  • To what extent do code-signing certificates boost sales of your software?

    - by Dan W
    In the experiences of everyone here, have you found a certificate to boost sales of your (downloadable) program? I produce .NET software and upon clicking the installation file, Windows 7 pops up a message saying the software is from an "unknown publisher" and to proceed with caution. For Windows 8, this appears to be even more prominent, and may adversely affect the number of downloads, and therefore the number of sales. A certificate will help soften this 'warning' by (for example) changing the warning's colour from orange to blue, and give the publisher's name instead of 'unknown'. But I'd like more tangible evidence since many people are obviously used to that message, and may not care and download anyway. So has anyone noticed a jump in sales after the switch?

  • How does copyrights apply to source code header files?

    - by Jim McKeeth
    It seems I heard that header files are not considered copyrightable since they can only be written one way (like a list of ingredients or facts). So a header file for a specific DLL will always look the same when written in a given programming language. Unfortunately I can't find any resources to back this up. So if a vendor provides an SDK with headers in one programming language, and then those headers are translated into another programming language by a third party. Does the 3rd party need permission from the vendor to provide the header translation? Who owns the copyright on the translation? Isn't it a derivative work still owned by the vendor, or is there no copyright, like a list of ingredients? Does this vary from jurisdiction to jurisdiction?

  • Moving a body in a specific direction using XNA with Farseer Physics

    - by Code Assasssin
    I have a custom polygon attached to a body, which looks like this: What I am trying to accomplish is getting the body to move according to wherever the tip of the body is. So far this is what I've tried: if (ks.IsKeyDown(Keys.Up)) { body.ApplyForce(new Vector2(0, -20),body.GetLocalPoint(new Vector2(0,0))); } if (ks.IsKeyDown(Keys.Left)) { body.ApplyTorque(-500); } if (ks.IsKeyDown(Keys.Right)) { body.ApplyTorque(500); } The body rotates fine - but when I try making the body accelerate according to the tip of the body - assuming I have specified the tip correctly(I am pretty sure I haven't), it just spins around, as if I have applied Torque to it. Can anyone point me in the right direction of how to fix this problem?

  • The Healthy Tension That Mobility Creates

    - by Kathryn Perry
    A guest post by Hernan Capdevila, Vice President, Oracle Fusion Apps In my previous post, I talked about the value of the mobile revolution on businesses and workers. Now let me put on a different hat and view the world from the IT department and the IT leader’s viewpoint. The IT leader has different concerns – around privacy, potential liability of information leakage, and intellectual property protection. These concerns and the leader’s goals create a healthy tension with the users. For example, effective device management becomes a must have for the IT leader, especially if you look at the Android ecosystem as an example. There are benefits to the Android strategy, but there are also drawbacks, such as uniformity – in device management, in operating systems, and in the application taxonomy and capabilities. Whereas, if you compare Android to iOS, Apple's operating system, iOS is more unified, more streamlined, and easier to manage. In either case, this is where mobile device management in the cloud makes good sense. I don't think IT departments should be hosting device management and managing that complexity. It should be a cloud service and I predict it's going to be key for our customers. A New Focus for IT Departments So where does that leave the IT departments? I think their futures are in governance, which is a more strategic play than a tactical one. Device management is tactical and it's the “now” topic. But the mobile phenomenon, if you will, is going to drive significant change in terms of how IT plans, hosts, and deploys enterprise applications. For example, opening up enterprise applications for mobile users presents some challenges unless you deploy more complicated network topologies, such as virtual private networks and threat protection technology. If you really want employees to be mobile you need to remove those kinds of barriers. But I don’t think IT departments want to wrestle with exposing their private enterprise data centers and being responsible for hosted business applications – applications in a sense that they’re making vulnerable to the public world. This opens up a significant need and a significant driver for cloud applications. However, it's not just about taking away the complexity – it's also about taking away the responsibility. Why should every business have to carry the responsibility and figure out all the nuts and bolts of how to protect themselves in this public, mobile world? When you use apps in the cloud, either your vendor or your hosting partner should have figured all that out. They need to assure the business that they are adhering to all sorts of security and compliance regulations so users can be connected and have access to information anywhere anytime. More Ideas and Better Service What’s more interesting is the world of possibilities that the connected, cloud-based world enables. I believe that the one-size-fits-all, uber-best practices, lowest-common denominator-like capabilities will go away. IT will now be able to solve very specific business challenges for the different corporate functions it serves. In this new world, IT will play a key role in enabling different organizations within a company to be best in class and delivering greater value to the line of business managers. IT will actually help to differentiate. Net result is a more agile workforce and business because each department is getting work done its own way.

  • Sucking Less Every Year?

    - by AdityaGameProgrammer
    Sucking Less Every Year -Jeff Atwood I had come across this insightful article.Quoting directly from the post I've often thought that sucking less every year is how humble programmers improve. You should be unhappy with code you wrote a year ago. If you aren't, that means either A) you haven't learned anything in a year, B) your code can't be improved, or C) you never revisit old code. All of these are the kiss of death for software developers. How often does this happen or not happen to you? How long before you see an actual improvement in your coding ? month, year? Do you ever revisit Your old code? How often does your old code plague you? or how often do you have to deal with your technical debt. It is definitely very painful to fix old bugs n dirty code that we may have done to quickly meet a deadline and those quick fixes ,some cases we may have to rewrite most of the application/code. No arguments about that. Some of the developers i had come across argued that they were already at the evolved stage where their coding doesn't need improvement or cant get improved anymore. Does this happen? If so how many years into coding on a particular language does one expect this to happen? Related: Ever look back at some of your old code and grimace in pain? Star Wars Moment in Code "Luke! I am your code!" "No! Impossible! It can't be!"

  • Does TDD's "Obvious Implementation" mean code first, test after?

    - by natasky
    My friend and I are relatively new TDD and have a dispute about the "Obvious Implementation" technique (from "TDD By Example" by Kent Beck). My friend says it means that if the implementation is obvious, you should go ahead and write it - before any test for that new behavior. And indeed the book says: How do you implement simple operations? Just implement them. Also: Sometimes you are sure you know how to implement an operation. Go ahead. I think what the author means is you should test first, and then "just implement" it - as opposed to the "Fake It ('Till You Make It)" and other techniques, which require smaller steps in the implementation stage. Also after these quotes the author talks about getting "red bars" (failing tests) when doing "Obvious Implementation" - how can you get a red bar without a test?. Yet I couldn't find any quote from the book saying "obvious" still means test first. What do you think? Should we test first or after when the implementation is "obvious" (according to TDD, of course)? Do you know a book or blog post saying just that?

  • Where do I get the source code to customize Unity?

    - by Muhammad Khan
    So one of the main reasons I migrated to Ubuntu 12.04 from Windows 7 was to be able to have more control over my system due to the flexibility and customizability of a Linux operating system. However, with Ubuntu I do not feel as if I am as in control as I can be. What I mean to say is, where are the source codes and everything for all of this that I can edit on my machine. For example, suppose I want to position my dock on the left to be on the right without wanting to install any new software. I simply want to see the GUI files and reposition it myself. How can I do that, if that's even possible? Thank You!

  • Agile project management, agile development: early integration

    - by Matías Fidemraizer
    I believe that agile works if everything is agile. In software development area, in my opinion, if team members' code is integrated early, code will be more in sync and this has a lot of pros: Early integration helps team members to avoid painful merges. Encourages better coding habits, because everyone makes sure that they don't break co-workers' code everyday. Both developers and architects (code reviewers) may detect bad design decisions or just wrong development directions in real-time, preventing useless work. Actually I'm talking about getting the latest version of code base and checking-in your own code to the source control in a daily basis. When you start your coding day (i.e. you arrive to your work), your first action is updating your code base with the latest version from the source control. In the other hand, when you're about an hour to leave from your work and go home, your last action is checking-in your code to the source control and be sure that your day work doesn't break the project's build process. Rather than updating and checking-in your code once you finished an entire task, I believe the best approach is fixing small and flexible personal milestones and checking-in the code once you finish one of these. I really believe that this coding approach fits better in the agile project management concept. Do you know some document, blog post, wiki, article or whatever that you can suggest me that could be in sync with my opinion?. And, do you find any problem working with this approach?. Thank you in advance.

  • PerlRegEx vs RegularExpressionsCore Delphi Units

    - by Jan Goyvaerts
    The RegularExpressionsCore unit that is part of Delphi XE is based on the latest class-based PerlRegEx unit that I developed. Embarcadero only made a few changes to the unit. These changes are insignificant enough that code written for earlier versions of Delphi using the class-based PerlRegEx unit will work just the same with Delphi XE. The unit was renamed from PerlRegEx to RegularExpressionsCore. When migrating your code to Delphi XE, you can choose whether you want to use the new RegularExpressionsCore unit or continue using the PerlRegEx unit in your application. All you need to change is which unit you add to the uses clause in your own units. Indentation and line breaks in the code were changed to match the style used in the Delphi RTL and VCL code. This does not change the code, but makes it harder to diff the two units. Literal strings in the unit were separated into their own unit called RegularExpressionsConsts. These strings are only used for error messages that indicate bugs in your code. If your code uses TPerlRegEx correctly then the user should not see any of these strings. My code uses assertions to check for out of bounds parameters, while Embarcadero uses exceptions. Again, if you use TPerlRegEx correctly, you should never get any assertions or exceptions. The Compile method raises an exception if the regular expression is invalid in both my original TPerlRegEx component and Embarcadero’s version. If your code allows the user to provide the regular expression, you should explicitly call Compile and catch any exceptions it raises so you can tell the user there is a problem with the regular expression. Even with user-provided regular expressions, you shouldn’t get any other assertions or exceptions if your code is correct. Note that Embarcadero owns all the rights to their RegularExpressionsCore unit. Like all the other RTL and VCL units, this unit cannot be distributed by myself or anyone other than Embarcadero. I do retain the rights to my original PerlRegEx unit which I will continue to make available for those using older versions of Delphi.
