  • How to do a login page for third party service without letting them sign on?

    - by AAA
    We have a unique situation (at least for me, first time seeing this). We have a web form where accountants can fill in requests and that part is taken care of. But after their login we redirect them to a third-party website where we need more information from them. The process is crazy right now since we have to give our account login info to all people filing with us. So is there a way in PHP or any other solution where we can after that form on our website auto login with our information to that third party website in a way that our credentials are not visible to the users using the service?

  • Applications: The Mathematics of Movement, Part 3

    - by TechTwaddle
    Previously: Part 1, Part 2 As promised in the previous post, this post will cover two variations of the marble move program. The first one, Infinite Move, keeps the marble moving towards the click point, rebounding it off the screen edges and changing its direction when the user clicks again. The second version, Finite Move, is the same as first except that the marble does not move forever. It moves towards the click point, rebounds off the screen edges and slowly comes to rest. The amount of time that it moves depends on the distance between the click point and marble. Infinite Move This case is simple (actually both cases are simple). In this case all we need is the direction information which is exactly what the unit vector stores. So when the user clicks, you calculate the unit vector towards the click point and then keep updating the marbles position like crazy. And, of course, there is no stop condition. There’s a little more additional code in the bounds checking conditions. Whenever the marble goes off the screen boundaries, we need to reverse its direction.  Here is the code for mouse up event and UpdatePosition() method, //stores the unit vector double unitX = 0, unitY = 0; double speed = 6; //speed times the unit vector double incrX = 0, incrY = 0; private void Form1_MouseUp(object sender, MouseEventArgs e) {     double x = e.X - marble1.x;     double y = e.Y - marble1.y;     //calculate distance between click point and current marble position     double lenSqrd = x * x + y * y;     double len = Math.Sqrt(lenSqrd);     //unit vector along the same direction (from marble towards click point)     unitX = x / len;     unitY = y / len;     timer1.Enabled = true; } private void UpdatePosition() {     //amount by which to increment marble position     incrX = speed * unitX;     incrY = speed * unitY;     marble1.x += incrX;     marble1.y += incrY;     //check for bounds     if ((int)marble1.x < MinX + marbleWidth / 2)     {         marble1.x = MinX + marbleWidth / 2;         unitX *= -1;     }     else if ((int)marble1.x > (MaxX - marbleWidth / 2))     {         marble1.x = MaxX - marbleWidth / 2;         unitX *= -1;     }     if ((int)marble1.y < MinY + marbleHeight / 2)     {         marble1.y = MinY + marbleHeight / 2;         unitY *= -1;     }     else if ((int)marble1.y > (MaxY - marbleHeight / 2))     {         marble1.y = MaxY - marbleHeight / 2;         unitY *= -1;     } } So whenever the user clicks we calculate the unit vector along that direction and also the amount by which the marble position needs to be incremented. The speed in this case is fixed at 6. You can experiment with different values. And under bounds checking, whenever the marble position goes out of bounds along the x or y direction we reverse the direction of the unit vector along that direction. Here’s a video of it running;   Finite Move The code for finite move is almost exactly same as that of Infinite Move, except for the difference that the speed is not fixed and there is an end condition, so the marble comes to rest after a while. Code follows, //unit vector along the direction of click point double unitX = 0, unitY = 0; //speed of the marble double speed = 0; private void Form1_MouseUp(object sender, MouseEventArgs e) {     double x = 0, y = 0;     double lengthSqrd = 0, length = 0;     x = e.X - marble1.x;     y = e.Y - marble1.y;     lengthSqrd = x * x + y * y;     //length in pixels (between click point and current marble pos)     length = Math.Sqrt(lengthSqrd);     //unit vector along the same direction as vector(x, y)     unitX = x / length;     unitY = y / length;     speed = length / 12;     timer1.Enabled = true; } private void UpdatePosition() {     marble1.x += speed * unitX;     marble1.y += speed * unitY;     //check for bounds     if ((int)marble1.x < MinX + marbleWidth / 2)     {         marble1.x = MinX + marbleWidth / 2;         unitX *= -1;     }     else if ((int)marble1.x > (MaxX - marbleWidth / 2))     {         marble1.x = MaxX - marbleWidth / 2;         unitX *= -1;     }     if ((int)marble1.y < MinY + marbleHeight / 2)     {         marble1.y = MinY + marbleHeight / 2;         unitY *= -1;     }     else if ((int)marble1.y > (MaxY - marbleHeight / 2))     {         marble1.y = MaxY - marbleHeight / 2;         unitY *= -1;     }     //reduce speed by 3% in every loop     speed = speed * 0.97f;     if ((int)speed <= 0)     {         timer1.Enabled = false;     } } So the only difference is that the speed is calculated as a function of length when the mouse up event occurs. Again, this can be experimented with. Bounds checking is same as before. In the update and draw cycle, we reduce the speed by 3% in every cycle. Since speed is calculated as a function of length, speed = length/12, the amount of time it takes speed to reach zero is directly proportional to length. Note that the speed is in ‘pixels per 40ms’ because the timeout value of the timer is 40ms.  The readability can be improved by representing speed in ‘pixels per second’. This would require you to add some more calculations to the code, which I leave out as an exercise. Here’s a video of this second version,

  • Trying to boot from usb

    - by iron
    I have similar issues but none with the 12.04 build. Im trying this on a dell d610 laptop with a bad hard drive and was told i could just directly boot from the usb drive. Im using an 8g usb drive and i have tried using the uui tool and get this message. SYSLINUX 4.06 EDD 4.06-pre1 Copyright (c) 1994-2011 H.Peter Anvinet al ERROR: No configuration file found No DEFAULT or UI configuration directive found! Then i tried using unetbootin and got the bootup screen with only the default option and it would say auto boot with a 10 sec countdown and start over again. I do have the boot sequence for usb first.

  • Why did this command make my Ubuntu more awesome than before?

    - by the_misfit
    After running Ubuntu for months and liking it, I for the first time wanted to use headphones and was trying to get them to work so I ran the code in step 1 https://help.ubuntu.com/community/SoundTroubleshootingProcedure -- the result was an improvement in performance, resolution, and audio.. a vast improvement. What does that suggest about what was wrong with my settings before if running this improved system performance, graphics, and my audio problem? The command is: sudo add-apt-repository ppa:ubuntu-audio-dev/ppa; sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; killall pulseaudio; rm -r ~/.pulse*; sudo usermod -aG `cat /etc/group | grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e '^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g'` `whoami`

  • Can it be useful to build an application starting with the GUI?

    - by Grant Palin
    The trend in application design and development seems to be starting with the "guts": the domain, then data access, then infrastructure, etc. The GUI seems to usually come later in the process. I wonder if it could ever be useful to build the GUI first... My rationale is that by building at least a prototype GUI, you gain a better idea of what needs to happen behind the scenes, and so are in a better position to start work on the domain and supporting code. I can see an issue with this practice in that if the supporting code is not yet written, there won't be much for the GUI layer to actually do. Perhaps building mock objects or throwaway classes (somewhat like is done in unit testing) would provide just enough of a foundation to build the GUI on initially. Might this be a feasible idea for a real project? Maybe we could add GDD (GUI Driven Development) to the acronym stable...

  • NVidia control panel SSAO not working

    - by János Turánszki
    I am just before implementing screen space ambient occlusion in my game, but first I wanted to try enabling it from NVidia control panel only to find out that it is greyed out so that I can not enable it. With this I could enable SSAO for some other games, but not every one. I know this technique requires the depth buffer and (optionally) a normal map texture to sample information from which I already have access to given I have a deferred renderer working. After that I actually thought to roll back to a previous version of my game which still uses forward rendering so the depth buffer is actually bound to the backbuffer which I render to from the get-go so that maybe the NVidia control panel would somehow make use of it. It was not working with forward rendering either. (I also tried FXAA in the control panel and that works - but it doesn't need any depth or normal texture) So my question is that how can I enable this function so that it would work by enabling it in the NVidia control panel?

  • After the update today no graphical interface anymore - 12.04

    - by Mark
    I installed the updates through the update manager today. I shut down my Laptop and now after starting it up again, I only get terminal access to advices. Grub is loading fine and after I picked Ubuntu 12.04 the screen get blank and I am asked to log in with my username and password in command line mode. If I log in I am still in command line mode. How do I get the "normal (graphical)" Ubuntu back? I hope you know what I mean. Since English is not my first language I can't explain this the way I would like to. Mark

  • Problem installing LibreOffice; please help!

    - by EmmyS
    I followed the instructions for installing LibreOffice found here, which are basically the same instructions found all over askubuntu and the web in general. I followed the instructions (including removing OO first) for gnome; all that is in my Applications menu now is LibreOffice (OO used to have OpenOffice Spreadsheet, OpenOffice Presentation, etc.) When I open LibreOffice, I get the splash screen/menu, but all of the choices for creating new docs are greyed out. It also will not open any office/type files (no errors; they just don't open.) The terminal commands indicated that installation was successful, but obviously something is missing. I'm guessing I can just reinstall OO from the software center, but I'd really like to give LibreOffice a try, given the lack of ongoing development on OO. Can anyone help me out?

  • Bzr to git migration

    - by Sardathrion
    I am planning to do two things on several large (several gigs) and old (several years) repositories: Move from bzr to git without losing the commit history. Restructure all the repositories either using bzr or git. This will involve moving files/directories from one repository to another with its change history. Doing both at once would be foolish (I think!) but I am not sure which one should be done first. Any suggestions? Anything I should watch out for when migrating/restructuring?

  • As a Junior Software Engineer should I say that something has been done wrong if I feel so?

    - by Why123
    I recently joined a company and it is my first job. When reading the code base, I felt that the code was not well written. It seemed to me that the code had most of the problems mentioned here and also seemed to have an Anemic Domain Model. There are no unit tests and they don't employ any code quality checking tools like findbugs or pmd. The problem I have is that the code is very difficult to understand. Maybe my conclusions are wrong because I am not that experienced. I need advice on whether to communicate the above facts to a superior or not. If I am to communicate, to whom(Tech Lead, Architect, Product Manager) and how? And if I do communicate will they take it badly since I'm a Junior and has no experience?

  • Ruby - when to use instance variables vs parameters between methods?

    - by Michael Durrant
    I'm writing several methods that call other methods. To pass the information I have a couple of choices: Pass the information as parameters Set instance variables so that other methods can access them When should I choose one option over the other? It seems that the first option is good as it is very specific about what is being passed. the downside seems to be that a lot of values are being passed around. The second method doesn't require passing all the values around but seems to lead to a lot of magic where methods set instance variables 'somewhere' Should I always be very explicit about gets passed to other methods in the class? Are there exceptions so this?

  • Need some help implementing VBO's with Frustum Culling

    - by Isracg
    i'm currently developing my first 3D game for a school project, the game world is completely inspired by minecraft (world completely made out of cubes). I'm currently seeking to improve the performance trying to implement vertex buffer objects but i'm stuck, i already have this methods implemented: Frustum culling, only drawing exposed faces and distance culling but i have the following doubts: I currently have about 2^24 cubes in my world, divided in 1024 chunks of 16*16*64 cubes, right now i'm doing immediate mode rendering, which works well with frustum culling, if i implement one VBO per chunk, do i have to update that VBO each time i move the camera (to update the frustum)? is there a performance hit with this? Can i dynamically change the size of each VBO? of do i have to make each one the biggest possible size (the chunk completely filled with objects)?. Would i have to keep each visited chunk in memory or could i efficiently remove that VBO and recreated it when needed?.

  • The new Google Analytics - what new useful features have you found?

    - by Rob
    If you don't know already a new version of Google Analytics has just come out. On first initial views it doesn't seem like much of an improvement on the previous version. There's lot's linking to Google's social stats but I'm yet to see the value of that. Also it doesn't seem to make the best use of the important data, it's tending to push referral sites, keywords to the back and bring the less important data to the front. Is that a sign of things to come??? One feature I did find interesting was the visitors flow as it shows the visitors path through your site. What new features have you found useful/interesting?

  • Notifications not working in Gnome 3.4

    - by chazdg
    Notifications are no longer working in Gnome 3.4 but they are working in Unity. I have tried everything I can think of but I am stumped. To clarify, I am changing the theme using Gnome Tweak. Themes were obtained from various repositories including noobslab/themes and webupd8. As an example, when using the default theme adwaita, I get all notifications when using Rhythmbox as to what song is being played on an internet radio station. I even tried a different media player with the same result. When I change the theme, all I get is a media player Icon. Change back to default theme and all Notifications work fine. Notifications were working at first with all themes, but no longer. The question is how to get Notifications to work for all themes. They did for previous versions of Gnome-shell.

  • Wubi on Windows 8 without secure boot?

    - by emersonhsieh
    I have a MacBook Pro. I've heard rumours that if Windows 8 is going to have this thing called "Secure boot", Wubi cannot work. At first I plan to install Ubuntu on my mac via Wubi(and windows via bootcamp), but since I can't find my Windows 7 Installation CD, I installed Windows 8 on my Mac and installed Ubuntu on a VM. Then suddenly Windows 8 Release Preview was released today so I decided to install over my existing copy of Windows 8 Consumer Preview. When I went to the Windows 8 Upgrade assistant, it said that the firmware on my Mac doesn't support Secure booting. I don't even know what it means, but since the Upgrade assistant said that the Mac cannot support secure booting, can I install Wubi successfully? And what is secure booting anyways? Any help will be appreciated.

  • 11.10 had sound, 12.04 doesnt. Acer Aspire One D257

    - by Jeff Welling
    I'm wondering if anyone else has had this same problem, because if so it might be worth while for me to file a bug, but it might also be chaos monkey so I wanted to check first. I have an Acer Aspire One D257 and the sound worked in 11.10 by default, but after doing a fresh install of 12.04 there is no sound. There used to be a speaker icon on the menu bar but now there isn't, and volume up and volume down hotkeys now do nothing, which leads me to believe it isn't detecting the sound card properly anymore. Googling for sound problems on an Acer Aspire One D257 on 12.04 isn't showing any helpful results, so I'm wondering if it's just me. Does anyone have an AAO D257 on 12.04 with the sound working, and if so did you have to do anything special to make it work?

  • What time to display in text messages in multiplayer game?

    - by Krom Stern
    Say I'm having a multiplayer RTS game. There's a main server for each individual game and several clients connected to it. All packets are sent to server first and then server retransmits them back to clients. Say Server is located in one time-zone and all of the clients are in different time-zones. ClientA send a text message in chat at 12:03, what times should be stamped for other clients? Should his message be uniformely timestamped by Server (12:02) or each client should timestamp the message whenever it is recieved (12:04, 16:04, 03:03, etc..). Bear in mind, that all the messages are to be in the same order on all clients, server takes care of that. So thats the question - use local time for each client or use global server time to timestamp chat messages?

  • Optimizing hierarchical transform

    - by Geotarget
    I'm transforming objects in 3D space by transforming each vector with the object's 4x4 transform matrix. In order to achieve hierarchical transform, I transform the child by its own matrix, and then the child by the parent matrix. This becomes costly because objects deeper in the display tree have to be transformed by all the parent objects. This is what's happening, in summary: Root -- transform its verts by Root matrix Parent -- transform its verts by Parent, Root matrix Child -- transform its verts by Child, Parent, Root matrix Is there a faster way to transform vertices to achieve hierarchical transform? What If I first concatenated each transform matrix with the parent matrices, and then transform verts by that final resulting matrix, would that work and wouldn't that be faster? Root -- transform its verts by Root matrix Parent -- concat Parent, Root matrices, transform its verts by Concated matrix Child -- concat Child, Parent, Root matrices, transform its verts by Concated matrix

It was interesting to hear definite patterns emerging from those conversations: “BPM is a journey”, “experiences to share”, “our organization now understands what BPM is”, and my favorite (with some caveats): “BPM is like wine tasting, once you start, you want to try more”. These customers have started their journey, climbed up the learning curve, and reached a vantage point that allows them to see their next BPM destination. They see the next few processes they are going to tackle and improve with BPM. These processes/destinations target both horizontal processes where BPM replaces or coordinates manual activities, and critical industry processes that the company needs to improve to compete and deliver increasing value. Each new destination generates value, allowing the organization to reduce the cost of manual processes that were not supported by apps/custom development, and increase efficiency of end-to-end processes partially covered by apps/custom dev. The question we wanted to answer is how to help organizations experience deeper success with BPM, by increasing their awareness of the potential for reaching new targets, and equipping them with the right tools. We decided that we needed to identify destinations, and plot routes to show the fastest path to those destinations. In the end we want to enable customers to reach “Process Excellence”: continuously set new targets and consistently and efficiently reach them. The result is Oracle Process Accelerators (PA), solutions built using the rich functionality in Oracle BPM Suite. PAs offers a rapidly expanding list of exciting destinations. Our launch of the latest installment of Process Accelerators at Oracle Open World includes new Industry-focused solutions such as Public Sector Incident Reporting and Financial Services Loan Origination, and improved other horizontal PAs, including Travel Request Management, Document Routing and Approval, and Internal Service Requests. Just before OOW we had extended the Oracle deployment of Travel Request Management, riding the enthusiastic response from early adopters among travelers (employees), management and support (approvers). “Getting there first” means being among the first to extract value from the PA approach, while acquiring deeper insights into the customers’ perspective. This is especially noteworthy when it comes to PAs, a set of solutions designed to be quickly deployed and iteratively improved by customers. The OOW launch has generated immediate feedback from customers, non-customers, analysts, and partners. They all confirmed that both Business and IT at organizations benefit from PAs when it comes to exploring the potential for BPM to improve their business processes. PAs help customers visualize what can be done with BPM, and PAs are made to be extended: you can see your destination, change the path to fit your needs, and deploy. We're discovering new destinations/processes that the market wants us to support, generic enough across industries and within industries. We'll keep on building sets of requirements, deliver functional design, construct solutions using Oracle BPM, and test them not only functionally but for performance, scalability, clustering, making them robust, product-quality. Delivering BPM solutions with product-grade quality is the equivalent of following a tried-and-tested path on a map. Do you know of existing destinations in your industry? If yes, we can draw a path to innovative processes together.
