  • Tab completion COMP_WORDS bad array subscript

    - by Senthil Kumaran
    I have upgraded my Ubuntu to 10.04 and I am facing this problem of COMP_WORDS bad array subscript when I press TAB for certain completion. I thought, it is a bug with bash-completion package and I purged it. But even after that, I still face this. If it is a bug with bash package, how I can resolve it? https://bugs.launchpad.net/ubuntu/+source/bash-completion/+bug/366446 It is difficult for a developer to live with this bug in the system.

  • Defining .NET Components with Namespaces

    A .NET software component is a compiled set of classes that provide a programmable interface that is used by consumer applications for a service. As a component is no more than a logical grouping of classes, what then is the best way to define the boundaries of a component within the .NET framework? How should the classes inter-operate? Patrick Smacchia, the lead developer of NDepend, discusses the issues and comes up with a solution.

  • Visual Studio 2012 and Oracle Development Environment

    - by John Paul Cook
    Creating a complete environment for developing .NET applications that target Oracle requires a little planning and understanding of how Oracle connectivity works. You need to be methodical and test along the way so that you aren’t trying to troubleshoot a multitude of interrelated problems at the end. I’ve made several assumptions in writing this post: You are using 64-bit Windows 7 because you are developer with a lot of ram. I think this post will help you even if you are running Windows 8 instead...(read more)

  • Diminishing Returns on Additional Developers

    - by smp7d
    Is there a term to describe the point at which adding more developers to a software project will provide diminishing returns? I realize that at a high level, it is more complicated that just a number of developers at which the project will be at productive capacity (ex/ state of the project, quality of the added developer), but I am trying to come up with a way to relate this to non-technical management through repetition. I'm basically looking for a term which invokes a strong image like "terminal velocity", except for Brook's Law.

  • Non-public site for testing on shared-hosting site

    - by ptpaterson
    Is it possible to as a developer using a shared hosting site such as bluehost, hostgator, and the like, to view your site without making it public. Or do the files you upload always go live immediately? Is the best way to test a site (if using shared hosting) to just set up some apache/mysql/php service on my machine? I am considering putting together a site with shared hosting, and trying to see what all my options are. Thanks.

  • Running C++ AMP kernels on the CPU

    - by Daniel Moth
    One of the FAQs we receive is whether C++ AMP can be used to target the CPU. For targeting multi-core we have a technology we released with VS2010 called PPL, which has had enhancements for VS 11 – that is what you should be using! FYI, it also has a Linux implementation via Intel's TBB which conforms to the same interface. When you choose to use C++ AMP, you choose to take advantage of massively parallel hardware, through accelerators like the GPU. Having said that, you can always use the accelerator class to check if you are running on a system where the is no hardware with a DirectX 11 driver, and decide what alternative code path you wish to follow.  In fact, if you do nothing in code, if the runtime does not find DX11 hardware to run your code on, it will choose the WARP accelerator which will run your code on the CPU, taking advantage of multi-core and SSE2 (depending on the CPU capabilities WARP also uses SSE3 and SSE 4.1 – it does not currently use AVX and on such systems you hopefully have a DX 11 GPU anyway). A few things to know about WARP It is our fallback CPU solution, not intended as a primary target of C++ AMP. WARP stands for Windows Advanced Rasterization Platform and you can read old info on this MSDN page on WARP. What is new in Windows 8 Developer Preview is that WARP now supports DirectCompute, which is what C++ AMP builds on. It is not currently clear if we will have a CPU fallback solution for non-Windows 8 platforms when we ship. When you create a WARP accelerator, its is_emulated property returns true. WARP does not currently support double precision.   BTW, when we refer to WARP, we refer to this accelerator described above. If we use lower case "warp", that refers to a bunch of threads that run concurrently in lock step and share the same instruction. In the VS 11 Developer Preview, the size of warp in our Ref emulator is 4 – Ref is another emulator that runs on the CPU, but it is extremely slow not intended for production, just for debugging. Comments about this post by Daniel Moth welcome at the original blog.

    - by Ziv
    I'm about to go in a very intensive programming course (8AM-8PM every day of the week for three months), at the end of which I will be given a developer job-the job's quality and the project I will work on will depend on my performance in the course. Getting a good position in the company could be very beneficial and I would very much want that, does anyone have specific techniques or ways that he keeps himself concentrated on a goal for a long period of time?

  • Seven Accounting Changes for 2010

    - by Theresa Hickman
    I read a very interesting article called Seven Accounting Changes That Will Affect Your 2010 Annual Report from SmartPros that nicely summarized how 2010 annual financial statements will be impacted.  Here’s a Reader’s Digest version of the changes: 1.  Changes to revenue recognition if you sell bundled products with multiple deliverables: Old Rule: You needed to objectively establish the “fair value” of each bundled item. So if you sold a dishwasher plus installation and could not establish the fair value of the installation, you might have to delay recognizing revenue of the dishwasher days or weeks later until it was installed. New Rule (ASU 2009-13): “Objective” proof of each service or good is no longer required; you can simply estimate the selling price of the installation and warranty. So the dishwasher vendor can recognize the dishwasher revenue immediately at the point of sale without waiting a few weeks for the installation. Then they can recognize the estimated value of the installation after it is complete. 2.  Changes to revenue recognition for devices with embedded software: Old Rule: Hardware devices with embedded software, such as the iPhone, had to follow stringent software revrec rules. This forced Apple to recognize iPhone revenues over two years, the period of time that software updates were provided. New Rule (ASU 2009-14): Software revrec rules no longer apply to these devices with embedded software; these devices can now follow ASU 2009-13. This allows vendors, such as Apple, to recognize revenue sooner. 3.  Fair value disclosures: Companies (both public and private) now need to spend extra time gathering, summarizing, and disclosing information about items measured at fair value, such as significant transfers in and out of Level 1(quoted market price), Level 2 (valuation based on observable markets), and Level 3 (valuations based on internal information). 4.  Consolidation of variable interest entities (a.k.a special purpose entities): Consolidation rules for variable interest entities now require a qualitative, not quantitative, analysis to determine the primary beneficiary. Instead of simply looking at the percentage of voting interests, the primary beneficiary could have less than the majority interests as long as it has the power to direct the activities and absorb any losses.  5.  XBRL: Starting in June 2011, all U.S. public companies are required to file financial statements to the SEC using XBRL. Note: Oracle supports XBRL reporting. 6.  Non-GAAP financial disclosures: Companies that report non-GAAP measures of performance, such as EBITDA in SEC filings, have more flexibility.  The new interpretations can be found here: http://www.sec.gov/divisions/corpfin/guidance/nongaapinterp.htm.  7.  Loss contingencies disclosures: Companies should expect additional scrutiny of their loss disclosures, such as those from litigation losses, in their annual financial statements. The SEC wants more disclosures about loss contingencies sooner instead of after the cases are settled.

  • Top down space game control problem

    - by Phil
    As the title suggests I'm developing a top down space game. I'm not looking to use newtonian physics with the player controlled ship. I'm trying to achieve a control scheme somewhat similar to that of FlatSpace 2 (awesome game). I can't figure out how to achieve this feeling with keyboard controls as opposed to mouse controls though. Any suggestions? I'm using Unity3d and C# or javaScript (unityScript or whatever is the correct term) works fine if you want to drop some code examples. Edit: Of course I should describe FlatSpace 2's control scheme, sorry. You hold the mouse button down and move the mouse in the direction you want the ship to move in. But it's not the controls I don't know how to do but rather the feeling of a mix of driving a car and flying an aircraft. It's really well made. Youtube link: FlatSpace2 on iPhone I'm not developing an iPhone game but the video shows the principle of the movement style. Edit 2 As there seems to be a slight interest, I'll post the version of the code I've used to continue. It works good enough. Sometimes good enough is sufficient! using UnityEngine; using System.Collections; public class ShipMovement : MonoBehaviour { public float directionModifier; float shipRotationAngle; public float shipRotationSpeed = 0; public double thrustModifier; public double accelerationModifier; public double shipBaseAcceleration = 0; public Vector2 directionVector; public Vector2 accelerationVector = new Vector2(0,0); public Vector2 frictionVector = new Vector2(0,0); public int shipFriction = 0; public Vector2 shipSpeedVector; public Vector2 shipPositionVector; public Vector2 speedCap = new Vector2(0,0); void Update() { directionModifier = -Input.GetAxis("Horizontal"); shipRotationAngle += ( shipRotationSpeed * directionModifier ) * Time.deltaTime; thrustModifier = Input.GetAxis("Vertical"); accelerationModifier = ( ( shipBaseAcceleration * thrustModifier ) ) * Time.deltaTime; directionVector = new Vector2( Mathf.Cos(shipRotationAngle ), Mathf.Sin(shipRotationAngle) ); //accelerationVector = Vector2(directionVector.x * System.Convert.ToDouble(accelerationModifier), directionVector.y * System.Convert.ToDouble(accelerationModifier)); accelerationVector.x = directionVector.x * (float)accelerationModifier; accelerationVector.y = directionVector.y * (float)accelerationModifier; // Set friction based on how "floaty" controls you want shipSpeedVector.x *= 0.9f; //Use a variable here shipSpeedVector.y *= 0.9f; //<-- as well shipSpeedVector += accelerationVector; shipPositionVector += shipSpeedVector; gameObject.transform.position = new Vector3(shipPositionVector.x, 0, shipPositionVector.y); } }

  • Ubuntu App Submission won't allow the "free" bubble to be checked

    - by Compt
    I am at the final stages of the Ubuntu App Developer Showdown, and I'm right at the point where I am submitting my app. The problem I run in to however, is that even though buy is at $0.00, it will not allow me to click on the "free" button, and keep that configuration saved. So when I go to "preview your app", it shows it saying "USD $0.00 ---- Buy" instead of saying "Free ---- Install". So I was wondering if it makes any difference or not.
