• Introducing Agile development after traditional project inception

  - by Riggy

  About a year and a half ago, I entered a workplace that claimed to do Agile development. What I learned was that this place has adopted several agile practices (such as daily standups, sprint plannings and sprint reviews) but none of the principles (just in time / just good enough mentality, exposing failure early, rich communication). I've now been tasked with making the team more agile and I've been assured that I have complete buy-in from the devs and the business team. As a pilot program, they've given me a project that just completed 15 months of requirements gathering, has a 110 page Analysis & Design document (to be considered as "written in stone"), and where I have no access to the end users (only to the committee made up of the users' managers who won't actually be using the product). I started small, giving them a list of expected deliverables for the first 5 sprints (leaving the future sprints undefined), a list of goals for the first sprint, and I dissected the A&D doc to get enough user stories to meet the first sprint's goals. Since then, they've asked why we don't have all the requirements for all the sprints, why I haven't started working on stuff for the third sprint (which they consider more important but is based off of the deliverables of the first 2 sprints) and are pressing for even more documentation that my entire IT team considers busy-work or un-related to us (such as writing the user manual up-front, documenting all the data fields from all the sprints up front, and more "up-front" work). This has been pretty rough for me as a new project manager, but there are improvements I have effectively implemented such as scrumban for story management, pair programming, and having the business give us customer acceptance tests up front (as part of the requirements documentation). So my questions are: What can I do to more effectively introduce change to a resistant business? Are there other practices that I can introduce on the IT side to help show the business the benefits of agile? The burden of documentation is strangling us - the business still sees it as a risk management strategy instead of as a risk. What can we do to alleviate their documentation concerns and demands (specifically the quantity of documentation and their need for all of it up front)? We are in a separate building from our business, about 3 blocks away and they refuse to have their people on the project co-habitate b/c that person "won't be able to work on their other projects while they're at our building." They expect us to always go over there and to bundle our questions so that we can ask them all at once and not waste that person's time with "constant interruptions." What can we do to get richer communication from them? Any additional advice would also be appreciated. Thanks!

• Open port in gufw is closed, no incoming connection on deluge

  - by user66987

  I have a problem configuring gufw. I open ports on it, but when i test in deluge it shows as closed. Any help on setting up the firewall would be greatly appreciated. This is the output I get on the firewall in terminal: Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN 1346/dnsmasq tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN 970/cupsd tcp 0 0 0.0.0.0:55521 0.0.0.0:* LISTEN 17362/python tcp6 0 0 ::1:631 :::* LISTEN 970/cupsd tcp6 0 0 :::55521 :::* LISTEN 17362/python udp 0 0 10.0.0.125:1900 0.0.0.0:* 17362/python udp 0 0 127.0.0.1:1900 0.0.0.0:* 17362/python udp 0 0 0.0.0.0:1900 0.0.0.0:* 17362/python udp 0 0 127.0.0.1:53162 0.0.0.0:* 17362/python udp 0 0 127.0.0.1:53 0.0.0.0:* 1346/dnsmasq udp 0 0 0.0.0.0:68 0.0.0.0:* 1312/dhclient udp 0 0 10.0.0.125:36948 0.0.0.0:* 17362/python udp 0 0 0.0.0.0:37240 0.0.0.0:* 17362/python udp 0 0 10.0.0.125:6771 0.0.0.0:* 17362/python udp 0 0 127.0.0.1:6771 0.0.0.0:* 17362/python udp 0 0 0.0.0.0:6771 0.0.0.0:* 17362/python udp 0 0 10.0.0.125:50034 0.0.0.0:* 17362/python udp 0 0 0.0.0.0:58340 0.0.0.0:* 982/avahi-daemon: r udp 0 0 0.0.0.0:5353 0.0.0.0:* 982/avahi-daemon: r udp 0 0 0.0.0.0:56947 0.0.0.0:* 17362/python udp 0 0 127.0.0.1:57059 0.0.0.0:* 17362/python udp6 0 0 :::49793 :::* 982/avahi-daemon: r udp6 0 0 :::5353 :::* 982/avahi-daemon: r kenneth@kenneth-K53U:~$ sudo ufw status Status: aktive Til Handling Fra --- -------- --- 6881:6891/tcp ALLOW Anywhere 6881:6891/udp ALLOW Anywhere 55521/tcp ALLOW Anywhere 6881:6891/tcp ALLOW Anywhere (v6) 6881:6891/udp ALLOW Anywhere (v6) 55521/tcp ALLOW Anywhere (v6) I also want to be able to use the firewall with linuxdc, so I need other ports open as well. This is connected to the firewall. Because when I turn off the firewall, the port is open. So this is not a problem with my modem. Do I need the firewall? The broadband modem has a hardware firewall. Update: Forgot to add. When my firewall is inactive, it closes ports after a time. So when I use linuxdc, I have to flush iptabels and activating it again. Is this supposed to do this when the firewall is deactivated? Update again: All my ports are closed now, flushing the iptable does not work anymore. I have uninstalled gufw, but still all my ports are closed. And to say it again, this has nothing to do with my broadband modem since it worked when I used windows 7. I need help to open the ports.

• How to wrap console utils in webserver

  - by Alex Brown

  I have a big dataset (100Mbs/day) and a bunch of console a TCL/TK tools to view it - I want to turn it into a web app that I can build, and others can maintain. In long: my group runs simulations yielding 100s of Mbs of data daily, in multiple (mostly but not only) text forms. We have a bunch of scripts and tools, mostly old school 1990's style stuff requiring a 5-button mouse, as well as lots of ad-hoc scripts that engineers build out of frustration every month or so. These produces UIs, graphs, spreadsheets (various sizes), logs, event histories etc. I want to replace (or at least supplement) the xwindows / console style UI with a web-based one, so I need the following properties: pleasant to program can wrap existing command-line tools in separate views (I don't need to scrape GUIs or anything) as I port logic from the existing scripts I can create a modularised and pleasant codebase to replace it I can attach a web-ui to navigate between views - each view is likely to contain keys which might make sense to view in another I am new to building systems that have logic on the back-end and front-end of a web-server. from that point of view, they do this: backend wraps old-school executables, constructs calls into them and them takes the output and wraps it up, niceifies it and delivers it to the web client. For instance the tool might generate a number of indexed images (per invocation) which I might deliver all at once or on-demand. May (probably) need to to heavy stats on some sources. frontend provides navigation connecting multiple views, performs requests from one view for data from another (or self to self), etc. Probably will have some views with a lot of interactivity. Can people please point me towards viable solutions for this? I know it's a bit of an open question so as answers come in I hope to refine the spec until we have a good match. I guess I expect to see answers like "RoR!" "beans!" "Scala!" but please give an indication of why those are a good fit; I know nothing! I got bumped off SO for asking an open-ended question, so sorry if its OT here too (let me know). I take the policy that I use the best/closest matched language for a project but most of my team are extremely low level (ie pipeline stages and CDyn) so I don't have the peer group to know where to start.

• Calling functions from different classes

  - by A Ron Hubbard Clevenger

  I'm writing a program and I'm supposed to check and see if a certain object is in the list before I call it. I set up the contains() method which is supposed to use the equals() method of the Comparable interface I implemented on my Golfer class but it doesn't seem to call it (I put print statements in to check). I can't seem to figure out whats wrong with the code, the ArrayUnsortedList class I'm using to go through the list even uses the correct toString() method I defined in my Golfer class but for some reason it won't use the equals() method I implemented. //From "GolfApp.java" public class GolfApp{ ListInterface <Golfer>golfers = new ArraySortedList<Golfer> (20); Golfer golfer; //..*snip*.. if(this.golfers.contains(new Golfer(name,score))) System.out.println("The list already contains this golfer"); else{ this.golfers.add(this.golfer = new Golfer(name,score)); System.out.println("This golfer is already on the list"); } //From "ArrayUnsortedList.java" protected void find(T target){ location = 0; found = false; while (location < numElements){ if (list[location].equals(target)) //Where I think the problem is { found = true; return; } else location++; } } public boolean contains(T element){ find(element); return found; } //From "Golfer.java" public class Golfer implements Comparable<Golfer>{ //..irrelavant code sniped..// public boolean equals(Golfer golfer) { String thisString = score + ":" + name; String otherString = golfer.getScore() + ":" + golfer.getName() ; System.out.println("Golfer.equals() has bee called"); return thisString.equalsIgnoreCase(otherString); } public String toString() { return (score + ":" + name); } My main problem seems to be getting the find function of the ArrayUnsortedList to call my equals function in the find() part of the List but I'm not exactly sure why, like I said when I have it printed out it works with the toString() method I implemented perfectly. I'm almost positive the problem has to do with the find() function in the ArraySortedList not calling my equals() method. I tried using some other functions that relied on the find() method and got the same results.

• Learn programming backwards, or "so I failed the FizzBuzz test. Now what?"

  - by moraleida

  A Little Background I'm 28 today, and I've never had any formal training in software development, but I do have two higher education degrees equivalent to a B.A in Public Relations and an Executive MBA focused on Project Management. I've worked on those fields for about 6 years total an then, 2,5 years ago I quit/lost my job and decided to shift directions. After a month thinking things through I decided to start freelancing developing small websites in WordPress. I self-learned my way into it and today I can say I run a humble but successful career developing themes and plugins from scratch for my clients - mostly agencies outsourcing some of their dev work for medium/large websites. But sometimes I just feel that not having studied enough math, or not having a formal understanding of things really holds me behind when I have to compete or work with more experienced developers. I'm constantly looking for ways to learn more but I seem to lack the basics. Unfortunately, spending 4 more years in Computer Science is not an option right now, so I'm trying to learn all I can from books and online resources. This method is never going to have NASA employ me but I really don't care right now. My goal is to first pass the bar and to be able to call myself a real programmer. I'm currently spending my spare time studying Java For Programmers (to get a hold on a language everyone says is difficult/demanding), reading excerpts of Code Complete (to get hold of best practices) and also Code: The Hidden Language of Computer Hardware and Software (to grasp the inner workings of computers). TL;DR So, my current situation is this: I'm basically capable of writing any complete system in PHP (with the help of Google and a few books), integrating Ajax, SQL and whatnot, and maybe a little slower than an experienced dev would expect due to all the research involved. But I was stranded yesterday trying to figure out (not Google) a solution for the FizzBuzz test because I didn't have the if($n1 % $n2 == 0) method modulus operator memorized. What would you suggest as a good way to solve this dilemma? What subjects/books should I study that would get me solving problems faster and maybe more "in a programmers way"? EDIT - Seems that there was some confusion about what did I not know to solve FizzBuzz. Maybe I didn't express myself right: I knew the steps needed to solve the problem. What I didn't memorize was the modulus operator. The problem was in transposing basic math to the program, not in knowing basic math. I took the test for fun, after reading about it on Coding Horror. I just decided it was a good base-comparison line between me and formally-trained devs. I just used this as an example of how not having dealt with math in a computer environment before makes me lose time looking up basic things like modulus operators to be able to solve simple problems.

• Where can I hire local programmers with very specific skillsets?

  - by Lostsoul

  I have been browsing the site and haven't found a exact fit to this question so I'll post it but if its already answered(since I'm sure its a common problem, then let me know). I have a business and want to create a totally different product in a different industry than I'm currently in, so I learned how to program and created a working prototype. I have a bit of savings and am getting some cash flow from my current business so I can go out and hire a developer(in the future hopefully it can be permenant but right now I just need a person willing to work on contract and code on weekends or their spare time and I just want to pay in cash instead of equity or future promises). At first I wasn't sure what kind of developer to hire but this question helped me understand I should target specific skills I need as opposed to general programmers. This poses a problem for me since general programmers are everywhere but if I want specific skills I'm unsure how to get them. I thought about a list of approaches but it doesn't feel complete or effective since it seems to be assuming good developers are actively looking. If it helps I want someone local(since this is my first developer hire) and looking for skills like cuda, hadoop, hbase, java and c. Any suggestions? As a FYI, I have been thinking of approaching it as: Go to meet ups for one or more skills I need. Use LinkedIn to find people with the skills I need Search for job postings that contain skills I need and then use linkedIn to reach out to that firms employees since many profiles on linkedin are not very updated or detailed but job postings generally are. Send postings to universities and maybe find a student who loves technology so much they learned these tools on their own. Post on job board. Not sure how successful it will be to post to monster. Use Craigslist, not sure if a highly skilled developer would go here for work. What am I missing? I could be wrong but it seems like good/smart/able developers aren't hunting for work non-stop(especially in this tech job market). Plus most successful people I know have work/life balance so I'm not sure if the best ones really care about code after work. Lastly, most of the skills I need aren't used in big corporations so not sure how aggressively smart developers at small shops look for work. I don’t really know any developers personally, so but should I be using the above plan or if they live balanced lives should I be looking outside of the regular resources(and instead focus on asking around my gym or my accountant or something)? Sorry, I'm making huge assumptions here, I guess because developers are a total mystery to me. I kind of wish Jane Goodall wrote a book on understanding developers social behaviour better :-p

• Get Specific depth values in Kinect (XNA)

  - by N0xus

  I'm currently trying to make a hand / finger tracking with a kinect in XNA. For this, I need to be able to specify the depth range I want my program to render. I've looked about, and I cannot see how this is done. As far as I can tell, kinect's depth values only work with pre-set ranged found in the depthStream. What I would like to do is make it modular so that I can change the depth range my kinect renders. I know this has been down before but I can't find anything online that can show me how to do this. Could someone please help me out? I have made it possible to render the standard depth view with the kinect, and the method that I have made for converting the depth frame is as follows (I've a feeling its something in here I need to set) private byte[] ConvertDepthFrame(short[] depthFrame, DepthImageStream depthStream, int depthFrame32Length) { int tooNearDepth = depthStream.TooNearDepth; int tooFarDepth = depthStream.TooFarDepth; int unknownDepth = depthStream.UnknownDepth; byte[] depthFrame32 = new byte[depthFrame32Length]; for (int i16 = 0, i32 = 0; i16 < depthFrame.Length && i32 < depthFrame32.Length; i16++, i32 += 4) { int player = depthFrame[i16] & DepthImageFrame.PlayerIndexBitmask; int realDepth = depthFrame[i16] >> DepthImageFrame.PlayerIndexBitmaskWidth; // transform 13-bit depth information into an 8-bit intensity appropriate // for display (we disregard information in most significant bit) byte intensity = (byte)(~(realDepth >> 8)); if (player == 0 && realDepth == 00) { // white depthFrame32[i32 + RedIndex] = 255; depthFrame32[i32 + GreenIndex] = 255; depthFrame32[i32 + BlueIndex] = 255; } // omitted other if statements. Simple changed the color of the pixels if they went out of the pre=set depth values else { // tint the intensity by dividing by per-player values depthFrame32[i32 + RedIndex] = (byte)(intensity >> IntensityShiftByPlayerR[player]); depthFrame32[i32 + GreenIndex] = (byte)(intensity >> IntensityShiftByPlayerG[player]); depthFrame32[i32 + BlueIndex] = (byte)(intensity >> IntensityShiftByPlayerB[player]); } } return depthFrame32; } I have a strong hunch it's something I need to change in the int player and int realDepth values, but i can't be sure.

• Retail in New York - a walk down 5th Avenue

  - by sarah.taylor(at)oracle.com

  It's the week of the NRF Big Show and all eyes in the retail industry are on New York. The Big Apple is famous for Big Retail -with a proliferation of incredibly iconic stores. The environment is exciting and familiar even to people visiting this small island for the first time. Most of us have travelled down Fifth Avenue watching movies and TV even if we have never set foot on American soil. I find it one of the most exciting retail cities in the world and I am thrilled this year to be here with so many of Oracle's International retail customers who are joining us for the Retail Exchange. The Oracle program brings retailers from all over the planet together to share ideas and be inspired by New York retail and the NRF event. The show celebrates its 100th year in 2011 and New York itself has been recognized globally as the capital of innovative retail for just as long.  Fifth Avenue is where many global brands have placed their flagship stores, and businesses are in constant competition to set themselves apart from their competitors - both in the store and from the street.  These flag ship retail destinations present what today's customers are finding most exciting and delightful about retail. For the tourist market, they may only visit these stores once, but the impression that a trip to a flagship store leaves with a customer can last a lifetime.  One of the stores that is currently turning heads on Fifth Avenue is Hollister, sister brand to Abercrombie and Fitch, which has filled its shop front with a massive live video (and audio) feed of surfers on the beach in California.  To complete the effect, they also have troughs of water in front of the video screens to bring the sea to the street.  And this isn't the only kind of surfing that retailers are considering today and multi-channel retail is a hot topic that all of the retailers joining the Retail Exchange are considering.   The rest of the world looks to the brands along Fifth Avenue for inspiration - how they take advantage of new opportunities, how they set themselves apart from their competitors and how they keep their products fresh and desirable. With these inspiring pioneers in New York, it's little wonder that NRF's Big Show is so popular, and that New York is viewed as one of the retail capitals of the world. It is a pleasure to be here with so many of the world's greatest international retailers.

  We recently performed a disaster recovery exercise which included the restoration of the MSDB database onto our DR server.  I did a quick google to see if there were any special considerations and found the following MS article.  Considerations for Restoring the model and msdb Databases (http://msdn.microsoft.com/en-us/library/ms190749(v=sql.105).aspx).   It said both the original and replacement servers must be on the same version,  I double-checked and in my case they are both SQL Server 2008 R2 SP1 (10.50.2500).. So I went ahead and stopped SQL Server agent, restored the database and restarted the agent.  Checked the jobs and they were all there, everything looked great, and was until the server was rebooted a few days later.Then the syspolicy_purge_history job started failing on the 3rd step with the error message “Unable to start execution of step 3 (reason: The PowerShell subsystem failed to load [see the SQLAGENT.OUT file for details]; The job has been suspended). The step failed.”   A bit more googling pointed me to the msdb.dbo.syssubsystems table SELECT * FROM msdb.dbo.syssubsystems WHERE start_entry_point ='PowerShellStart'   And in particular the value for the subsystem_dll. It still had the path to the SQLPOWERSHELLSS.DLL but on the old server. The DR instance has a different name to the live instance and so the paths are different.   This was quickly fixed with the following SQL Use msdb; GO sp_configure 'allow updates', 1 ; RECONFIGURE WITH OVERRIDE ; GO UPDATE msdb.dbo.syssubsystems SET subsystem_dll='C:\Program Files\Microsoft SQL Server\MSSQL10_50.DR\MSSQL\binn\SQLPOWERSHELLSS.DLL' WHERE start_entry_point ='PowerShellStart'; GO sp_configure 'allow updates', 0; RECONFIGURE WITH OVERRIDE ; GO Stopped and started SQL Server agent and now the job completes.   I then wondered if anything else might be broken, SELECT subsystem_dll FROM msdb.dbo.syssubsystems Shows a further 10 wrong paths – fortunately for parts of SQL (replication, SSIS etc) we aren’t using! Lessons Learnt 1.       DR exercises are a good thing! 2.       Keep the Live and DR environments as similar as possible.

• Lock mouse in center of screen, and still use to move camera Unity

  - by Flotolk

  I am making a program from 1st person point of view. I would like the camera to be moved using the mouse, preferably using simple code, like from XNA var center = this.Window.ClientBounds; MouseState newState = Mouse.GetState(); if (Keyboard.GetState().IsKeyUp(Keys.Escape)) { Mouse.SetPosition((int)center.X, (int)center.Y); camera.Rotation -= (newState.X - center.X) * 0.005f; camera.UpDown += (newState.Y - center.Y) * 0.005f; } Is there any code that lets me do this in Unity, since Unity does not support XNA, I need a new library to use, and a new way to collect this input. this is also a little tougher, since I want one object to go up and down based on if you move it the mouse up and down, and another object to be the one turning left and right. I am also very concerned about clamping the mouse to the center of the screen, since you will be selecting items, and it is easiest to have a simple cross-hairs in the center of the screen for this purpose. Here is the code I am using to move right now: using UnityEngine; using System.Collections; [AddComponentMenu("Camera-Control/Mouse Look")] public class MouseLook : MonoBehaviour { public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 } public RotationAxes axes = RotationAxes.MouseXAndY; public float sensitivityX = 15F; public float sensitivityY = 15F; public float minimumX = -360F; public float maximumX = 360F; public float minimumY = -60F; public float maximumY = 60F; float rotationY = 0F; void Update () { if (axes == RotationAxes.MouseXAndY) { float rotationX = transform.localEulerAngles.y + Input.GetAxis("Mouse X") * sensitivityX; rotationY += Input.GetAxis("Mouse Y") * sensitivityY; rotationY = Mathf.Clamp (rotationY, minimumY, maximumY); transform.localEulerAngles = new Vector3(-rotationY, rotationX, 0); } else if (axes == RotationAxes.MouseX) { transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityX, 0); } else { rotationY += Input.GetAxis("Mouse Y") * sensitivityY; rotationY = Mathf.Clamp (rotationY, minimumY, maximumY); transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0); } while (Input.GetKeyDown(KeyCode.Space) == true) { Screen.lockCursor = true; } } void Start () { // Make the rigid body not change rotation if (GetComponent<Rigidbody>()) GetComponent<Rigidbody>().freezeRotation = true; } } This code does everything except lock the mouse to the center of the screen. Screen.lockCursor = true; does not work though, since then the camera no longer moves, and the cursor does not allow you to click anything else either.

• Walmart's Mobile Self-Checkout

  - by David Dorf

  Reuters recently reported that Walmart was testing an iPhone-based self-checkout at a store near its headquarters.  Consumers scan items as they're placed in the physical basket, then the virtual basket is transferred to an existing self-checkout station where payment is tendered.  A very solid solution, but not exactly original. Before we go further, let's look at the possible cost savings for Walmart.  According to the article: Pushing more shoppers to scan their own items and make payments without the help of a cashier could save Wal-Mart millions of dollars, Chief Financial Officer Charles Holley said on March 7. The company spends about $12 million in cashier wages every second at its Walmart U.S. stores. Um, yeah. Using back-of-the-napkin math, I calculated Walmart's cashiers are making $157k per hour.  A more accurate statement would be saving $12M per year for each second saved on the average transaction time.  So if this self-checkout approach saves 2 seconds per transaction on average, Walmart would save $24M per year on labor.  Maybe.  Sometimes that savings will be used to do other tasks in the store, so it may not directly translate to less employees. When I saw this approach demonstrated in Sweden, there were a few differences, which may or may not be in Walmart's plans.  First, the consumers were identified based on their loyalty card.  In order to offset the inevitable shrink, retailers need to save on labor but also increase basket size, typically via in-aisle promotions.  As they scan items, retailers should target promos, and that's easier to do if you know some shopping history.  Last I checked, Walmart had no loyalty program. Second, at the self-checkout station consumers were randomly selected for an audit in which they must re-scan all the items just like you do at a typical self-checkout.  If you were found to be stealing, your ability to use the system can be revoked.  That's a tough one in the US, especially when the system goes wrong, either by mistake or by lying.  At least in my view, the Swedes are bit more trustworthy than the people of Walmart. So while I think the idea of mobile self-checkout has merit, perhaps its not right for Walmart.

• OpenGLES GLSL Shader attributes always bound to 0

  - by codemonkey

  So I have a very simple vertex shader as follows #version 120 attribute vec3 position; attribute vec3 inColor; uniform mat4 mvp; varying vec3 fragColor; void main(void){ fragColor = inColor; gl_Position = mvp * vec4(position, 1.0); } Which I load, as well as the fragment shader: #version 120 varying vec3 fragColor; void main(void) { gl_FragColor = vec4(fragColor,1.0); } Which I then load, compile, and link to my shader program. I check for link status using glGetProgramiv(shaderProgram, GL_LINK_STATUS, &shaderSuccess); which returns GL_TRUE so I think its ok. However, when I query the active attributes and uniforms using #ifdef DEBUG int totalAttributes = -1; glGetProgramiv(shaderProgram, GL_ACTIVE_ATTRIBUTES, &totalAttributes); for(int i=0; i<totalAttributes; ++i) { int name_len=-1, num=-1; GLenum type = GL_ZERO; char name[100]; glGetActiveAttrib(shaderProgram, GLuint(i), sizeof(name)-1, &name_len, &num, &type, name ); name[name_len] = 0; GLuint location = glGetAttribLocation(shaderProgram, name); fprintf(stderr, "Attribute %s is bound at %d\n", name, location); } int totalUniforms = -1; glGetProgramiv(shaderProgram, GL_ACTIVE_UNIFORMS, &totalUniforms); for(int i=0; i<totalUniforms; ++i) { int name_len=-1, num=-1; GLenum type = GL_ZERO; char name[100]; glGetActiveUniform(shaderProgram, GLuint(i), sizeof(name)-1, &name_len, &num, &type, name ); name[name_len] = 0; GLuint location = glGetUniformLocation(shaderProgram, name); fprintf(stderr, "Uniform %s is bound at %d\n", name, location); } #endif I get: Attribute inColor is bound at 0 Attribute position is bound at 1 Uniform mvp is bound at 0 Which leads to failure when trying to use the shader to render the objects. I have tried switching the order of declaration of position & inColor, but still, only position is bound with the other two giving 0 Can someone please explain why this is happening? Thanks

• Configuring Full-Text Search for pdf and docx files

  - by Lukasz Kurylo

  I think in may I was creating a little filters module based on Full Text-Search. I have configured my dev machine, the same for two testing servers – in our company for internal testing before we deployed it to client, and then on the testing client server. Until last week this build  was still on the testing server and finally we got feedback that we can deploy it on the production one. I only say that, I lost half a day because I had not correctly remembered what I was doing to configure the FTS on the previous servers and I had no notes for that. I foolishly believed in my memory. Lesson learned.   For future reference a bunch of steps to configure the FTS for searching in *.pdf and *.docx files (and by the way in other Office files like *.xlsx).   1. From the page (link) download and install the *.pdf IFilter for FTS. 2. To the PATH global system variable add path to the catalog, where you installed the plugin. Default for this version is: C:\Program Files\Adobe\Adobe PDF iFilter 9 for 64-bit platforms\bin 3. From the page (link) download a FilterPackx64.exe and install it. 4. Now from SSMS execute the following procedures: -sp_fulltext_service 'load_os_resources',1 -sp_fulltext_service 'verify_signature', 0 5. Restart the server 6. Now we must check if the plugins are visible: -select document_type, path from sys.fulltext_document_types where document_type = '.pdf' -select document_type, path from sys.fulltext_document_types where document_type = '.docx' 7. If we see a result, then we can assume that everything is ok*. 8. Right now we can create a catalog for FTS and indexes on appropriate columns.     *I lost a lot of hours to find out, why the plugin for the *.pdf files wasn’t indexed any file in the database, but in the sys.fulltext_document_types table there was available a line for this plugin. After the deeper investigation I found that the *.pdf files actually were indexed. At least the EOF sign was added to the indexes and nothing more for each file. In the end the problem was that, I forgot to add the /bin in the path to the plugin in PATH variable..

• Am I deluding myself? Business analyst transition to programmer

  - by Ryan

  Current job: Working as the lead business analyst for a Big 4 firm, leading a team of developers and testers working on a large scale re-platforming project (4 onshore dev, 4 offshore devs, several onshore/offshore testers). Also work in a similar capacity on other smaller scale projects. Extent of my role: Gathering/writing out requirements, creating functional specifications, designing the UI (basically mapping out all front-end aspects of the system), working closely with devs to communicate/clarify requirements and come up with solutions when we hit roadblocks, writing test cases (and doing much of the testing), working with senior management and key stakeholders, managing beta testers, creating user guides and leading training sessions, providing key technical support. I also write quite a few macros in Excel using VBA (several of my macros are now used across the entire firm, so there are maybe around 1000 people using them) and use SQL on a daily basis, both on the SQL compact files the program relies on, our SQL Server data and any Access databases I create. The developers feel that I am quite good in this role because I understand a lot about programming, inherent system limitations, structure of the databases, etc so it's easier for me to communicate ideas and come up with suggestions when we face problems. What really interests me is developing software. I do a fair amount of programming in VBA and have been wanting to learn C# for awhile (the dev team uses C# - I review code occasionally for my own sake but have not had any practical experience using it). I'm interested in not just the business process but also the technical side of things, so the traditional BA role doesn't really whet my appetite for the kind of stuff I want to do. Right now I have a few small projects that managers have given me and I'm finding new ways to do them (like building custom Access applications), so there's a bit here and there to keep me interested. My question is this: what I would like to do is create custom Excel or Access applications for small businesses as a freelance business (working as a one-man shop; maybe having an occasional contractor depending on a project's complexity). This would obviously start out as a part-time venture while I have a day job, but eventually become a full-time job. Am I deluding myself to thinking I can go from BA/part-time VBA programmer to making a full-time go of a freelance business (where I would be starting out just writing custom Excel/Access apps in VBA)? Or is this type of thing not usually attempted until someone gains years of full-time programming experience? And is there even a market for these types of applications amongst small businesses (and maybe medium-sized) businesses?

• Booting Ubuntu on HP Pavilion g7 - 13.04 [duplicate]

  - by death2040

  This question already has an answer here: My computer boots to a black screen, what options do I have to fix it? 24 answers I have a HP Pavilion G7 with an AMD A4 processor and Radeon graphics. I want to install Ubuntu on my laptop but whenever I put the Ubuntu live CD in it and boot to it, the screen shows the Ubuntu logo and the four little dots then after about a minute or two the screen goes black. I can tell the screen is still on but it doesn't have anything on it. I'm beginning to wonder if its a driver problem but I can't really install the drivers when I cant even get Ubuntu to show anything except a loading screen. I've already tried using 12.04 and 12.10 and all the others down to Ubuntu 10. none of them worked. All the other versions don't even show the Ubuntu logo. I'd prefer to have Ubuntu 13.04 on it if its possible but I haven't had any luck finding a solution. I've also tried using WUBI installer in Windows 7 but all that did was make my computer slower for windows and it does the same with the screen when i boot it to Ubuntu. I'm trying to use Ubuntu alongside Windows 7. I cant find any solution on Google. It wont load anything and I know that there is a program called grub on Ubuntu that I used on my desktop computer when it had graphics trouble but the trouble with my desktop was minor things like the screen would flash and then show weird patterns on the screen. But I can't find anything on what to do with the HP laptop. Please help. I use this laptop a lot for games on Windows 7 and I just want to use Ubuntu for when I take my laptop to school and for school stuff. Edit: I just tried booting it in nomodeset and some other things and still didn't work. It did boot up but now when it goes to install alongside windows it crashes and says Ubuntu is forcing reboot or something like that Also, this question is different from the black screen at boot issue because when I do use nomodeset on my computer and select install Ubuntu it will go as far as the screen where you can choose to replace Windows or run alongside Windows. Then after I click continue it ejects the live CD and turns off my computer without installing anything. The error message it shows when it ejects the disk says signal 15, shutting down - modem manager [1675]: <info> Caught nm-dispatcher.action: Caught signal 15, shutting down... *Deconfiguring network interfaces... Please remove installation media and close the tray (if any) then press ENTER *Deactivating swap... *Stopping remaining crypto disks... *stopping early crypto disks... unmount: /run/lock: not mounted unmount: /run/shm: not mounted

• Proper Usage of Arrays and Functions [closed]

  - by Ssegawa Victor

  Can some one help me write a C code that solves the following problem. PROBLEM Consider the faculty registrar who has to process results for 1st year 1st semester students. Students offer five courses CSC 1100, CSK 1101, CSC 1104, CSC 1105 and CSC 1106. The courses have credit units 4,4,4,3 and 3 respectively. Lecturers provide course work and exam marks. For each course, course work constitutes 40% of the final mark while the exam constitutes 60% of the final mark. The role of the registrar is to Compute the final mark for each student for each course. The final mark must be a whole number Compute the grade and grade point of the students for each course they offered. According to senate regulations, grades and grade points are awarded to final marks according to the following criteria Range Grade Grade Point 90 – 100 A+ 5.0 80 – 89 A 5.0 75 – 79 B+ 4.5 70 – 74 B 4.0 65 – 69 C+ 3.5 60 – 64 C 3.0 55 – 59 D+ 2.5 50 – 54 D 2.0 45 – 49 E 1.5 40 – 44 E- 1.0 0 – 39 F 0.0 Put a comment ‘Retake’ to a student for every course where the Grade Point is less than 2.0 Compute the cumulative grade point average CGPA for each student. The senate formula for CGPA is GGPA =(?_(i=1)^(i=N)¦?CU _i×GP _i ?)/(?_(i=1)^(i=N)¦CU i) Put a comment “Progress” for any student whose GGPA is greater than 2 and “Stay Put” on a student whose CGPA is less than 2 You are required to create a c program that considers a class of 25 students and: 1.Initializes an array ‘student’ which stores student names 2.Initializes arrays for course work and exam for each course. ‘cw_csc_1100’ and ‘ex_csc_1100’ store course work and exam marks (respectively) for CSC 1100. The same approach is considered for all other courses 3.Initializes the coursework and exam marks arrays with marks between 0 and 99 4.Write appropriate functions that will generate the final marks, generate grades, generate grade points, generate cumulative grade points, generate comments for students and comments for courses per student 5.Create appropriate arrays for final marks and insert the data there using the appropriate functions 6.Without having to create any extra arrays, use the functions created to generate a report per student that looks like the one bellow. Student Name: Ngubiri Course Unit Final mark Grade Grade Point Course Comment CSC 1100 43 E- 1.0 Retake CSK 1101 50 D 2.0 CSC 1104 59 D+ 2.5 CSC 1105 70 B 4.0 CSC 1106 65 C+ 3.5 CGPA 2.47 Overall Comment Progress NB It is advisable that the indices are used to identify the owners. Eg if student[x] is John, then cs_csc_100[x] should be a mark for John since the index is the same

• Why can't a blendShader sample anything but the current coordinate of the background image?

  - by Triynko

  In Flash, you can set a DisplayObject's blendShader property to a pixel shader (flash.shaders.Shader class). The mechanism is nice, because Flash automatically provides your Shader with two input images, including the background surface and the foreground display object's bitmap. The problem is that at runtime, the shader doesn't allow you to sample the background anywhere but under the current output coordinate. If you try to sample other coordinates, it just returns the color of the current coordinate instead, ignoring the coordinates you specified. This seems to occur only at runtime, because it works properly in the Pixel Bender toolkit. This limitation makes it impossible to simulate, for example, the Aero Glass effect in Windows Vista/7, because you cannot sample the background properly for blurring. I must mention that it is possible to create the effect in Flash through manual composition techniques, but it's hard to determine when it actually needs updated, because Flash does not provide information about when a particular area of the screen or a particular display object needs re-rendered. For example, you may have a fixed glass surface with objects moving underneath it that don't dispatch events when they move. The only alternative is to re-render the glass bar every frame, which is inefficient, which is why I am trying to do it through a blendShader so Flash determines when it needs rendered automatically. Is there a technical reason for this limitation, or is it an oversight of some sort? Does anyone know of a workaround, or a way I could provide my manual composition implementation with information about when it needs re-rendered? The limitation is mentioned with no explanation in the last note in this page: http://help.adobe.com/en_US/as3/dev/WSB19E965E-CCD2-4174-8077-8E5D0141A4A8.html It says: "Note: When a Pixel Bender shader program is run as a blend in Flash Player or AIR, the sampling and outCoord() functions behave differently than in other contexts.In a blend, a sampling function will always return the current pixel being evaluated by the shader. You cannot, for example, use add an offset to outCoord() in order to sample a neighboring pixel. Likewise, if you use the outCoord() function outside a sampling function, its coordinates always evaluate to 0. You cannot, for example, use the position of a pixel to influence how the blended images are combined."

• Pragmas and exceptions

  - by Darryl Gove

  The compiler pragmas: #pragma no_side_effect(routinename) #pragma does_not_write_global_data(routinename) #pragma does_not_read_global_data(routinename) are used to tell the compiler more about the routine being called, and enable it to do a better job of optimising around the routine. If a routine does not read global data, then global data does not need to be stored to memory before the call to the routine. If the routine does not write global data, then global data does not need to be reloaded after the call. The no side effect directive indicates that the routine does no I/O, does not read or write global data, and the result only depends on the input. However, these pragmas should not be used on routines that throw exceptions. The following example indicates the problem: #include <iostream extern "C" { int exceptional(int); #pragma no_side_effect(exceptional) } int exceptional(int a) { if (a==7) { throw 7; } else { return a+1; } } int a; int c=0; class myclass { public: int routine(); }; int myclass::routine() { for(a=0; a<1000; a++) { c=exceptional(c); } return 0; } int main() { myclass f; try { f.routine(); } catch(...) { std::cout << "Something happened" << a << c << std::endl; } } The routine "exceptional" is declared as having no side effects, however it can throw an exception. The no side effects directive enables the compiler to avoid storing global data back to memory, and retrieving it after the function call, so the loop containing the call to exceptional is quite tight: $ CC -O -S test.cpp ... .L77000061: /* 0x0014 38 */ call exceptional ! params = %o0 ! Result = %o0 /* 0x0018 36 */ add %i1,1,%i1 /* 0x001c */ cmp %i1,999 /* 0x0020 */ ble,pt %icc,.L77000061 /* 0x0024 */ nop However, when the program is run the result is incorrect: $ CC -O t.cpp $ ./a.out Something happend00 If the code had worked correctly, the output would have been "Something happened77" - the exception occurs on the seventh iteration. Yet, the current code produces a message that uses the original values for the variables 'a' and 'c'. The problem is that the exception handler reads global data, and due to the no side effects directive the compiler has not updated the global data before the function call. So these pragmas should not be used on routines that have the potential to throw exceptions.

• Monitor the Weather from Your Windows 7 Taskbar

  - by Asian Angel

  Keeping up with the weather forecast can be hard when you are extra busy with work. If you need a simple but nice looking way to integrate weather monitoring into your Taskbar then join us as we look at WeatherBar. Setting Up & Using WeatherBar To get started unzip the following files, place them in an appropriate “Program Files Folder”, and create a shortcut. When you start WeatherBar for the first time you will be presented with the following window and a random/default location. To get WeatherBar set up for your location there are only two settings to adjust (using the “Pencil & Gear Buttons”). Clicking on the “Pencil Button” will open up this small window…enter the name of your location and click “OK”. Next click on the “Gear Button” where you can choose the “Update Interval” and “Measurement Format” that best suits your needs. Click “OK” when finished and WeatherBar will be ready to go. That definitely looks nice. When you are finished viewing this window minimize it to the “Taskbar Icon” instead of clicking on the “Close Button”…otherwise the entire app will close. Left click on the “Taskbar Icon” to bring the window back up… Hovering the mouse over the “Taskbar Icon” provides a nice thumbnail of the weather forecast. Right clicking on the “Taskbar Icon” will display a nice mini forecast. Conclusion While WeatherBar may not be for everyone it does provide a nice easy way to monitor the weather from your “Taskbar” without taking up a lot of room.
