  • Is the tap-to-click issue solved

    - by AWE
    I'm just an average Joe when it comes to computing (maybe less then the average Joe) but I hate tap-to-click. In system and settings there is no touchpad tab? Is it true that this has been fixed? I'm using Dell inspiron N5110 xinput list: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? PS/2 Generic Mouse id=13 [slave pointer (2)] This is really strange because Dell is one of the top manufacturers in laptops and Ubuntu one of the top distros in Linux and Canonical claims that they are working closely with Dell.

  • Box2Dweb very slow on node.js

    - by Peteris
    I'm using Box2Dweb on node.js. I have a rotated box object that I apply an impulse to move around. The timestep is set at 50ms, however, it bumps up to 100ms and even 200ms as soon as I add any more edges or boxes. Here are the edges I would like to use as bounds around the playing area: // Computing the corners var upLeft = new b2Vec2(0, 0), lowLeft = new b2Vec2(0, height), lowRight = new b2Vec2(width, height), upRight = new b2Vec2(width, 0) // Edges bounding the visible game area var edgeFixDef = new b2FixtureDef edgeFixDef.friction = 0.5 edgeFixDef.restitution = 0.2 edgeFixDef.shape = new b2PolygonShape var edgeBodyDef = new b2BodyDef; edgeBodyDef.type = b2Body.b2_staticBody edgeFixDef.shape.SetAsEdge(upLeft, lowLeft) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(lowLeft, lowRight) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(lowRight, upRight) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(upRight, upLeft) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) Can box2d really become this slow for even two bodies or is there some pitfall? It would be very surprising given all the demos which successfully use tens of objects.

  • Can I set Ubuntu 12.10 to automatically reboot to Windows once only?

    - by Bill Tetzeli
    Is there some way when I'm in Ubuntu 12.10 that I can set it to reboot automatically to Windows just once, so that when I'm in Windows I can reboot and it will automatically boot back into Ubuntu? I need this because often when I travel I access my home computer for email and other personal info that I don't want to travel with or leave to the tender mercies of the "cloud". On rare occasions, I need to temporarily boot into Windows 7 to do something Windows-specific, but then I want to be able to boot back into Ubuntu because that's where most of my computing takes place. Any ideas? Thanks in advance! Bill

  • Learning to program on punchcards

    - by Plutor
    I'd like to try programming with punch cards once in my life. How can I do this? I'm in my 30s, and grew up entirely in the PC era, programming on computers with screens and keyboards. I want to experience the way my father and grandfather used to work. I imagine the hardware (and probably the cards themselves) are no longer manufactured. Are there any universities or museums with functioning punch card readers anymore? I'm in Boston, but I'm willing to travel to do this. I asked MetaFilter, and I got some mixed answers (along with a lot of "no, don't do this" nay-saying). I did get a pointer to the Retro-Computing Society Of Rhode Island, but I haven't received a response to my email to them yet.

  • Is there a quick way to convert camera raw files to DNG?

    - by dericke
    Before I switched from Windows to Ubuntu for my daily computing, I used Adobe's Photoshop Lightroom for processing photos from my DSLR. Adobe made it really straightforward to convert from proprietary camera raw files (in my case, .NEF) to DNG. I haven't found any way to convert NEF to DNG in Ubuntu yet. Most photography programs do process NEFs to JPG/TIFF/PNG/etc., but I'm looking for a converter for archival purposes. Are there any tools available, either standalone or built into another app, that can losslessly convert from NEF to DNG?

  • Monitoring Windows Azure Service Bus Endpoint with BizTalk 360?

    - by Michael Stephenson
    I'm currently working with a customer who is undergoing an initiative to expose some of their line of business applications to external partners and SAAS applications and as part of this we have been looking at using the Windows Azure Service Bus. For the first part of the project we were focused on some synchronous request response scenarios where an external application would use the Service Bus relay functionality to get data from some internal applications. When we were looking at the operational monitoring side of the solution it was obvious that although most of the normal server monitoring capabilities would be required for the on premise components we would have to look at new approaches to validate that the operation of the service from outside of the organization was working as expected. A number of months ago one of my colleagues Elton Stoneman wrote about an approach I have introduced with a number of clients in the past where we implement a diagnostics service in each service component we build. This service would allow us to make a call which would flex some of the working parts of the system to prove it was working within any SLA. This approach is discussed on the following article: http://geekswithblogs.net/EltonStoneman/archive/2011/12/12/the-value-of-a-diagnostics-service.aspx In our solution we wanted to take the same approach but we had to consider that the service clients were external to the service. We also had to consider that by going through Windows Azure Service Bus it's not that easy to make most of your standard monitoring solutions just give you an easy way to do this. In a previous article I have described how you can use BizTalk 360 to monitor things using a custom extension to the Web Endpoint Manager and I felt that we could use this approach to provide an excellent way to monitor our service bus endpoint. The previous article is available on the following link: http://geekswithblogs.net/michaelstephenson/archive/2012/09/12/150696.aspx   The Monitoring Solution BizTalk 360 currently has an easy way to hook up the endpoint manager to a url which it will then call and if a successful response is returned it then considers the endpoint to be in a healthy state. We would take advantage of this by creating an ASP.net web page which would be called by BizTalk 360 and behind this page we would implement the functionality to call the diagnostics service on our Service Bus endpoint. The ASP.net page could include logic to work out how to handle the response from the diagnostics service. For example if the overall result of the diagnostics service was successful but the call to the diagnostics service was longer than a certain amount of time then we could return an error and indicate the service is taking too long. The following diagram illustrates the monitoring pattern.   The diagnostics service which is hosted in the line of business application allows us to ping a simple message through the Azure Service Bus relay to the WCF services in the LOB application and we they get a response back indicating that the service is working fine. To implement this I used the exact same approach I described in my previous post to create a custom web page which calls the diagnostics service and then it would return an HTTP response code which would depend on the error condition returned or a 200 if it was successful. One of the limitations of this approach is that the competing consumer pattern for listening to messages from service bus means that you cannot guarantee which server would process your diagnostics check message but with BizTalk 360 you could simply add multiple endpoint checks so that it could access the individual on-premise web servers directly to ensure that each server is working fine and then check that messages can also be processed through the cloud. Conclusion It took me about 15 minutes to get a proof of concept of this up and running which was able to monitor our web services which had been exposed via Windows Azure Service Bus. I was then able to inherit all of the monitoring benefits of BizTalk 360 to provide an enterprise class monitoring solution for our cloud enabled API.

  • New PeopleSoft HCM 9.1 On Demand Standard Edition provides a complete set of IT services at a low, predictable monthly cost

    - by Robbin Velayedam
    At Oracle Open World last month, Oracle announced that we are extending our On Demand offerings with the general availability of PeopleSoft On Demand Standard Edition. Standard Edition represents Oracle’s commitment to providing customers a choice of solutions, technology, and deployment options commensurate with their business needs and future growth. The Standard Edition offering complements the traditional On Demand offerings (Enterprise and Professional Editions) by focusing on a low, predictable monthly cost model that scales with the size of your business.   As part of Oracle's open cloud strategy, customers can freely move PeopleSoft licensed applications between on premise and the various  on demand options as business needs arise.    In today’s business climate, aggressive and creative business objectives demand more of IT organizations. They are expected to provide technology-based solutions to streamline business processes, enable online collaboration and multi-tasking, facilitate data mining and storage, and enhance worker productivity. As IT budgets remain tight in a recovering economy, the challenge becomes how to meet these demands with limited time and resources. One way is to eliminate the variable costs of projects so that your team can focus on the high priority functions and better predict funding and resource needs two to three years out. Variable costs and changing priorities can derail the best laid project and capacity plans. The prime culprits of variable costs in any IT organization include disaster recovery, security breaches, technical support, and changes in business growth and priorities. Customers have an immediate need for solutions that are cheaper, predictable in cost, and flexible enough for long-term growth or capacity changes. The Standard Edition deployment option fulfills that need by allowing customers to take full advantage of the rich business functionality that is inherent to PeopleSoft HCM, while delegating all application management responsibility – such as future upgrades and product updates – to Oracle technology experts, at an affordable and expected price. Standard Edition provides the advantages of the secure Oracle On Demand hosted environment, the complete set of PeopleSoft HCM configurable business processes, and timely management of regular updates and enhancements to the application functionality and underlying technology. Standard Edition has a convenient monthly fee that is scalable by number of employees, which helps align the customer’s overall cost of ownership with its size and anticipated growth and business needs. In addition to providing PeopleSoft HCM applications' world class business functionality and Oracle On Demand's embassy-grade security, Oracle’s hosted solution distinguishes itself from competitors by offering customers the ability to transition between different deployment and service models at any point in the application ownership lifecycle. As our customers’ business and economic climates change, they are free to transition their applications back to on-premise at any time. HCM On Demand Standard Edition is based on configurability options rather than customizations, requiring no additional code to develop or maintain. This keeps the cost of ownership low and time to production less than a month on average. Oracle On Demand offers the highest standard of security and performance by leveraging a state-of-the-art data center with dedicated databases, servers, and secured URL all within a private cloud. Customers will not share databases, environments, platforms, or access portals with other customers because we value how mission critical your data are to your business. Oracle’s On Demand also provides a full breadth of disaster recovery services to provide customers the peace of mind that their data are secure and that backup operations are in place to keep their businesses up and running in the case of an emergency. Currently we have over 50 PeopleSoft customers delegating us with the management of their applications through Oracle On Demand. If you are a customer interested in learning more about the PeopleSoft HCM 9.1 Standard Edition and how it can help your organization minimize your variable IT costs and free up your resources to work on other business initiatives, contact Oracle or your Account Services Representative today.

  • Programming to ANSI standards (for engineering)

    - by Jake
    I am currently tasked to write a software to help engineers design standard compliant designs. If there is a bad design, software will report an error or warning. Maybe it's just me, but anyone who has done this should be familiar with the massive amounts of ANSI standards tables like this one: http://en.wikipedia.org/wiki/Nominal_Pipe_Size Computers are, as its name suggest, computing machines, not lookup machines. I feel that feeding formulas into computers and churning out standard compliant designs is much more efficient than doing memory intensive data lookups that are prone to human input errors and susceptible to "data updates". I actually think that there are formulas to calculate all those numbers, but nobody so far could give me that information. Anyone been through this before? What is THE best approach to this? Thanks for sharing.

  • What is the history of why bytes are eight bits?

    - by DarenW
    What where the historical forces at work, the tradeoffs to make, in deciding to use groups of eight bits as the fundamental unit ? There were machines, once upon a time, using other word sizes, but today for non-eight-bitness you must look to museum pieces, specialized chips for embedded applications, and DSPs. How did the byte evolve out of the chaos and creativity of the early days of computer design? I can imagine that fewer bits would be ineffective for handling enough data to make computing feasible, while too many would have lead to expensive hardware. Were other influences in play? Why did these forces balance out to eight bits? (BTW, if I could time travel, I'd go back to when the "byte" was declared to be 8 bits, and convince everyone to make it 12 bits, bribing them with some early 21st Century trinkets.)

  • D-fense! D-fense! ...for Java technology

    - by hinkmond
    Who needs defense when computing with the Java platform? Isn't "the best defense is a good offense"? At least in football and volleyball... See: The Best Defense Here's a quote: "The other Oracle tester page, Verify Java Version, consistently reports whether the latest version is installed. Just click the big red button to see if the 'recommended' version of Java is installed." So, go ahead and use Java technology! There is "nothing to fear but fear itself". I like that quote better.

  • Writing a spell checker similar to "did you mean"

    - by user888734
    I'm hoping to write a spellchecker for search queries in a web application - not unlike Google's "Did you mean?" The algorithm will be loosely based on this: http://catalog.ldc.upenn.edu/LDC2006T13 In short, it generates correction candidates and scores them on how often they appear (along with adjacent words in the search query) in an enormous dataset of known n-grams - Google Web 1T - which contains well over 1 billion 5-grams. I'm not using the Web 1T dataset, but building my n-gram sets from my own documents - about 200k docs, and I'm estimating tens or hundreds of millions of n-grams will be generated. This kind of process is pushing the limits of my understanding of basic computing performance - can I simply load my n-grams into memory in a hashtable or dictionary when the app starts? Is the only limiting factor the amount of memory on the machine? Or am I barking up the wrong tree? Perhaps putting all my n-grams in a graph database with some sort of tree query optimisation? Could that ever be fast enough?

  • Which specific programming activities do women, on average, perform better than men? [closed]

    - by blueberryfields
    Following a recent discussion with female associates in hiring positions for software development/engineering positions, I found out that this kind of information would be incredibly useful to helping make sure that the workforce shows a gender balance. So I went looking. I've found various literature speaking about risk-taking behaviour and patterns, and other statistical differences between men and women when it comes to work performance. See for example this article related to hedge fund management. I have yet to see any such comparison in the computing field. To restate the question: Which specific programming activities do women, on average, perform better than men? Please back up your answers with specific details, preferably by linking to relevant research or, failing that, explaining what you're basing the information on.

    For those of you primarily working on high performance computing for non-scientific purposes (as in no fortran) what are the ways by which you keep yourself abreast of the latest trends out there? Industry gossip? Random blogs from google? Search SO? I am into HPC recently and looking for the high level architectural landscape. Given that everyone from GPGPU coders to FPGA folks to Erlang developers claim they are into HPC, how are you keeping up with so much information?

  • Software Engineering: Off to a Bad Start?

    - by Bob Rhubart
    The opening remarks for Real Software Engineering, Living Social developer Glenn Vanderburg's keynote presentation at QCon 2012 in San Francisco, include this: The people who started the software engineering field and movement, from the very beginning, misunderstood two very important things: software and engineering. And as a result, the field went off in the wrong direction from the very start, and legitimized certain ways of doing things and certain paths of research that really have not been very fruitful. Vanderburg's presentation is fascinating, often funny, and well worth watching, especially in light of how cloud computing and other technological shifts are redefining IT roles.

  • What is the current frequency of my processor (CPU-Z equivalent)?

    - by Anake
    Is there a ubuntu program like CPU-Z which will show me the actual frequency of my processor? I do a fair amount of scientific computing which leads to me running my programs for up to 10 hrs. To alleviate this problem a little I overclock my CPU. However I can't see what the actual clock of my processor from within ubuntu which means I either have to restart and look at the bios or load into windows. If there was an applet or command line command to find out this information it would be very helpful. Thanks for your help

  • If I use locks, can my algorithm still be lock-free?

    - by Joe Pension
    A common definition of lock-free is that at least one process makes progress. 1 If I have a simple data structure such as a queue, protected by a lock, then one process can always make progress, as one process can acquire the lock, do what it wants, and release it. So does it meet the definition of lock-free? 1 See eg M. Herlihy, V. Luchangco, and M. Moir. Obstruction-free synchronization: Double-ended queues as an example. In Distributed Computing, 2003. "It is lock-free if it ensures only that some thread always makes progress".

  • Effecient finding of long-range spotting targets

    - by nihohit
    I'm creating a top-down 2d strategy game, with a square grid map. So far, I've used Bresenham's line drawing algorithm in a circle to determine what's in LOS of each unit, and then targedt one of the targets in the circle. Now I find that this limits my units to shoot only at targets that they see. I want to extend my targeting algorithm to target any other unit in range of my weapon, even if they're out of sight range of this given unit, if they're "spotted" by another friendly unit. In other words, I want to enable usage of weapons with ranges longer than sight range. Is there a better way than iterating over all sighted units and computing range and LOSto each of them?
