  • how can we have a person to allot and track tasks in agile development

    - by vignesh
    I understand that Agile team should be self organized and self driven, but is there a provision that I can have someone who will allot tasks to developers and ensure that all user stories will be completed on time?? For example if there are two persons in an agile team who are not self motivated to take up tasks and they will work only when task is assigned to them with a deadline, how can we deal this in Agile? The problem I face is that no one is fixing the deadlines for the tasks and the team is under delivering for the last two sprints. It will be better if we can have someone who can fix deadlines. IS there a provision for this in Agile

  • Installing Solaris Studio 12.2 on Ubuntu 10.04

    - by KronoS
    I'm having a dickens of a time installing Solaris Studio 12.2 on Ubuntu 10.04. I found this guide, however using the alien option isn't finding the correct files. I'm not exactly sure on the syntax of alien, its kinda alien to me. (sorry for the bad pun) Also, when I download the tar file, and extract it, there are errors everytime saying things like: "operation not permitted" cannot creat symlink to '../prod/bin/cc': Operation not permitted I've extracted with super user access, but to no avail. Any success from anyone else?

  • How should I handle missing resources?

    - by concept3d
    Your game expects a certain asset to be loaded, but it isn't found. How should the situation be handled? For example: Texture* grassTexture = LoadTexture("Grass.png"); // returns NULL; texture not found Mesh* car = LoadMesh("Car.obj"); // returns NULL; 3D mesh not found It might have been accidentally deleted by the user, corrupted or misspelled while in development. Some potential responses: Assertions (ideally only during development) Exit the game gracefully Throw an exception and try to handle it. Which way is best?

  • Install a different version of a package

    - by Michael Wiles
    I'm running lucid server and have installed tomcat. The version it installed is 6.0.24-2ubuntu1.6. Is this the version I'm tied to? Is it possible to install a more recent version? The one available from maverick is 6.0.28. Maybe I can add a source to provide my lucid install with this version? In the package manager user interface I can "force version". Is it possible to force version from command line alternative as well?

  • Can a 10-bit monitor connection preserve all tones in 8-bit sRGB gradients on a wide-gamut monitor?

    - by hjb981
    This question is about color management and the use of a higher color depth, 10 bits per channel (30 bits in total, resulting in 1.07 billion colors, or 1024 shades of gray, sometimes referred to as "deep color") compared to the standard of 8 bits per channel (24 bits in total, 16.7 million colors, 256 shades of gray, sometimes referred to as "true color"). Do not confuse with "32 bit color", which usually refers to standard 8 bit color with an extra channel ("alpha channel") for transparency (used to achieve effects like semi-transparent windows etc). The following can be assumed to be in place: 1: A wide-gamut monitor that supports 10-bit input. Further, it can be assumed that the monitor has been calibrated to its native gamut and that an ICC color profile has been created. 2: A graphics card that supports 10-bit output (and is connected to the monitor via DisplayPort). 3: Drivers for the graphics card that support 10-bit output. If applications that support 10-bit output and color profiles would be used, I would expect them to display images that were saved using different color spaces correctly. For example, both an sRGB and an adobeRGB image should be displayed correctly. If an sRGB image was saved using 8 bits per channel (almost always the case), then the 10-bit signal path would ensure that no tonal gradients were lost in the conversion from the sRGB of the image to the native color space of the monitor. For example: If the image contains a pixel that is pure red in 8 bits (255,0,0), the corresponding value in 10 bits would be (1023,0,0). However, since the monitor has a larger color space than sRGB, sending the signal (1023,0,0) to the monitor would result in a red that was too saturated. Therefore, according to the ICC color profile, the signal would be transformed into a different value with less red saturation, for example (987,0,0). Since there are still plenty of levels left between 0 and 987, all 256 values (0-255) for red in the sRGB color space of the file could be uniquely mapped to color-corrected 10-bit values in the monitor's native color space. However, if the conversion was done in 8 bits, (255,0,0) would be translated to (246,0,0), and there would now only be 247 available levels for the red channel instead of 256, degrading the displayed image quality. My question is: how does this work on Ubuntu? Let's say that I use Firefox (which is color-aware and uses ICC color profiles). Would I get 10-bit processing, thus preserving all levels of an 8-bit picture? What is the situation like for other applications, especially photo applications like Shotwell, Rawtherapee, Darktable, RawStudio, Photivo etc? Does Ubuntu differ from other operating systems (Linux and others) on this point?

  • Scrum - how to carry over a partially complete User Story to the next Sprint without skewing the backlog

    - by Nick
    We're using Scrum and occasionally find that we can't quite finish a User Story in the sprint in which it was planned. In true Scrum style, we ship the software anyway and consider including the User Story in the next sprint during the next Sprint Planning session. Given that the User Story we are carrying over is partially complete, how do we estimate for it correctly in the next Sprint Planning session? We have considered: a) Adjusting the number of Story Points down to reflect just the work which remains to complete the User Story. Unfortunately this will mess up reporting the Product Backlog. b) Close the partially-completed User Story and raise a new one to implement the remainder of that feature, which will have fewer Story Points. This will affect our ability to retrospectively see what we didn't complete in that sprint and seems a bit time consuming. c) Not bother with either a or b and continue to guess during Sprint Planning saying things like "Well that User Story may be X story points, but I know it's 95% finished so I'm sure we can fit it in."

The process is this: Firsly it became totally stopped or very slow for certain periods of 5 minutes. How could I do? After that it gets stopped (Even not totally because If I click on the bar I see a blinking response in the bar botton of the program I click on. It´s could be anything related with security (like the firewall or some virus)? Computer university: I usually experience this, using Matlab (R2007a) with System Generator (its respective compatible version) My personal laptop: It´s usually works well but when stopped periods became to appears I know in not much time it will became totally stopped. I usually see how Word 2007 get stopped and after a while my windows xp gets stopped. (well I can access to the the manage task pressing ctr+alt and...). The only solution I see is to kill program by program... My petition: Please, I need good references that help me how to think in order to avoid or to manage the problems previously described.

  • Right mix of planning and programing on a new project

    - by WarrenFaith
    I am about to start a new project (a game, but thats unimportant). The basic idea is in my head but not all the details. I don't want to start programming without planning, but I am seriously fighting my urge to just do it. I want some planning before to prevent refactoring the whole app just because a new feature I could think of requires it. On the other hand, I don't want to plan multiple months (spare time) and start that because I have some fear that I will lose my motivation in this time. What I am looking for is a way of combining both without one dominating the other. Should I realize the project in the way of scrum? Should I creating user stories and then realize them? Should I work feature driven? (I have some experience in scrum and the classic "specification to code" way.)

  • Permanently deleting files on Mac OS

    - by Jonik
    A while back, as relatively new Mac OS X user, I was surprised to learn that you cannot easily delete files. Directly, that is, without moving them to the trash first. On Windows and Linux this can obviously be done with ease, but not so on the Mac. I noticed this when trying clear up files from a USB memory stick — removing the files ("move to trash") does not free up space; that happens only after emptying the whole system-wide Trash. Not particularly convenient! (It seems stupid to have to empty the whole trashcan just to make some space on the USB stick. There might be gigabytes of stuff in there, and this sort of defeats its purpose - what if you'd actually need to restore something from the trash some day.) So, what's your way of getting around this? Have you bought a 3rd party application like RAW Trash for $16.95 just to delete files, or do you diligently empty the trashcan whenever needed? Or did I miss something? Also, can you convince me that this is actually the way it should be — that users shouldn't be able to fiddle with the filesystem easily? :)

  • How do I know if I am using Scrum methodologies?

    - by Jake
    When I first started at my current job, my purpose was to rewrite a massive excel-VBA workbook-application to C# Winforms because it was thought that the new C# app will fix all existing problems and have all the new features for a perfect world. If it were a direct port, in theory it would be easy as i just need to go through all the formulas, conditional formatting, validations, VBA etc. to understand it. However, that was not the case. Many of the new features are tightly dependant on business logic which I am unfamiliar with. As a solo programmer, the first year was spent solely on deciphering the excel workbook and writing the C# app. In theory, I had the business people to "help" me specify requirements, how GUI looks and work, and testing of the app etc; but in practice it is like a contant tsunami of feature creep. At the beginning of the second year I managed to convince the management that this is not going anywhere. I made them start from scratch with the excel-VBA. I have this "issue log" saved on the network, each time they found something they didn't like about the excel-VBA app, they will write it in there. I check the log daily and consolidate issues (in my mind) mainly into 2 groups: (1) requires massive change. (2) can be fixed in current version. For massive change issues, I make a copy of the latest excel-VBA and give it a new version number, then work on it whenever I can. For current version fixes, I make the changes in a few days to a week, and then immediately release it. I also ensure I update the same change in any in-progress massive change future versions. This has gone on for about 4 months and I feel it works great. I made many releases and solved many real issues, also understood the business logic more and more. However, my boss (non-IT trained) thinks what I am doing are just adhoc changes and that i am not looking at the "bigger picture". I am struggling to convince my boss that this works. So I hope to formalise my approach and maybe borrow a buzzword to confuse him. Incidentally, I read about Agile and SCRUM, about backlog and sprints. But it's all very vague to me still. QUESTION (finally): I want to tell him that this is SCRUM! But I want to hold my breath first and ask whether my current approach is considered SCRUM or SCRUM-like? How can I make it more SCRUM-like? Note that I have only myself, there's no project leader or teams.

  • How do you handle unfound resources?

    - by concept3d
    For example your game expects a certain asset to be loaded what is the best way to handle it if the resource isn't found, for example: Texture* grassTexture = LoadTexture("Grass.png");// returns NULL as texture is not found. Mesh* car = LoadMesh("Car.obj");// returns NULL as 3d mesh is not found What if for some reason the resource wasn't found e.g. deleted by user, misspelling while in development ? Should I use Assertions (which is only useful while in development? Exit the game gracefully ? or even thrown an exception and try to handle it? On a separate question, if I used a handle system instead of pointers (which I am already working on) I don't see how this would help me recover from unfound resources, Does a handle system help in situations like this?

  • Best practices for launching a new software version

    - by steve
    I rebuilt a web app to replace a version that we have been using for the last 3-4 years. We have a few thousand clients and a few hundred active users per day. The functionality is basically the same. The new version is a little bit faster with a few enhancement features and there are a lot of behind the scenes changes that the clients will never see. The UI is quite different but ultimately much easier to use and navigate. How should I go about having our clients stop using the old system and start using the new one? I am currently putting together a video that will play on the web site as well as within the app. The video will go through the pages and focus on some key changes. I was also thinking about an intro page that will display once the user logs in and explains some of the features.

  • Plug-in or framework recommendation for showing content preview fly-over in CMS

    - by Michael Huang
    The requirement is to have either front end plug-in or back end processor that generates the preview of contents (such as images, videos, PDF files, HTML pages) in a preview popup when user mouse hovers the content. I did some research on this, seems that there are assorted jquery plugins for each type of files, but what we are looking for is a framework that handles all types of file previews. Ideally, we want to generate preview images on the backend, considering the cost of retrieving content on front end. I did find some open source or proprietary CMS that provides this feature, but usually they are shipped as one suite and the API for file preview might not be open. Is there any java or jquery framework that handles file preview? Thanks a lot

  • How to enable hibernate on Ubuntu 13.10?

  • What is an effective way to organize tasks for a new project?

    - by Dulan
    Is there a practical solution to organizing the initial tasks for a new project? To elaborate, imagine the features/stories/goals are laid out for a project. How might one go about organizing those into sane tasks for the first few versions? The scenario I typically have in mind has the features listed as a high-level reference for what the end user-experience should involve. The tasks for constructing such features are then broken down into chunks (such as "create interface for X component"). Such a task is not necessarily "tied" to only that feature and may be useful when building subsequent features. Is breaking features down into small, code-able solutions valid? Or should they be slightly removed from any specific implementation? I do not expect that there is one "right" answer to this question, but I am looking for a fairly pragmatic and unobtrusive approach. As a note, I'm looking for solutions that are independent of any tools or "systems" used for managing the tasks themselves.

  • Changing the Start Menu Power Button - Setting does not work: only (Shut down) is available

    - by Martin
    This is the second time I try to change this setting on a Vista based OS and I can't get it to work again. OS: Windows Server 2002 SP2 (not R2) = Microsoft Windows [Version 6.0.6002] = Vista When I go to: Power Options - Change Plan Settings - Change advanced power settings - Power buttons and lid - Start menu power button - Setting: the available combo box will only show the option Shut down. No other options are available. This server is part of a domain and has not been set up by me. I have not yet talked with the domain admin, but as far as I could tell from googling, only Win7 has group policy options for the start menu. (And yes, OC I will talk to the domain admin to see if he has any clue - which I doubt.) (Edit: I have now talked to our domain admin, and he's got no clue either.) I'm responsible for this server and a local administrator but not a domain administrator. I switched off User Account Control (UAC) yesterday without problems. Since I always log into this machine via RDP and this being a server, the natural choice would be the option (Log out) and not (Shut down). What can I do to fix it or to find out why it cannot be changed? Thanks!

  • To track or not to track user created images for display in a dynamic website?

    - by Question Overflow
    I have a website that allows user to upload and display images. Currently, I am not using a database to track these user images. A folder having the user id as the folder name is created for each user and under each folder, the image files are labelled numerically with filenames ranging from 01.jpg to 20.jpg. Up to 20 such images can be displayed on each user page. I am using javascript to hide these images in case of any of them is absent. I have seen many websites having user images with unique random filenames and possibly tracking these files with a database Since obscurity is not something that I need for these web accessible images, is there any reason why I should track them with a DB? I am not sure if a reduction of 404 errors is a good enough reason to justify the added complexity of maintaining a database or can anyone enlighten me?

  • How to cope with "Hidden IT..." Who writes and maintains the ad-hoc software applications?

    - by matcauthon
    Bigger companies usually have the problem, that it is not possible to write all programs employees want (to save time and to optimize processes) due to a lack of staff and money. Then hidden programs will be created by some people having (at least some) coding experience (or by cheap students/interns...). Under some circumstances these applications will raise in importance and spread from one user to a whole department. Then there is the critical point: Who will maintain the application, add new features, ...? And this app is critical. It IS needed. But the intern has left the company. No one knows how it works. You only have a bunch of sources and some sort of documentation. How do you cope with these applications? Can you "forbid" them? Can you control them? Do you have to write all apps (not Excel macros or some minor stuff) in the IT department?

  • Implement an FTP server (no threads) - how to start?

    - by ironicaldiction
    As a semester project, I have the following specification: Write a simple single threaded ftp server. The ftp server is configurable from a configuration file. The config allows to set the interface (where the server listens), the roots of the served content, transfer log, and database of users and its passwords. The server allows to create a virtual filesystem. By a virtual filesystem, we mean a mapping of a served directory to the real directory on the filesystem. For example, the client tree will look like: /home/user1 maps to /mnt/x/home/user1 /www maps to /var/cache/www /home/user_list.txt maps to /var/ftpclient/user_list.txt The user will see /home/user1 directory and /www directory and the file /home/user_list.txt The course is in C++. The projects to this point have provided a lot of structure, such as a class header file to get you started on the program. My question is this: how can I get started on what seems like quite a massive project (I have 3 weeks to return a working implementation)?

  • Windows OS level file open event trigger

    - by john
    Colleagues, I have need to run a script/program on certain basic OS level events. In particular when a file in Windows is opened. The open may be read-only or to edit, and may be initiated by a number of means, either from windows explorer (open or ), be selected from a viewing or editing application from the native file chooser, or drag-n-drop into an editing or viewing application. Further, i need the trigger to "hold" the event from completing the action until the runtime on the program has completed. The event handler program may return a pass state, or fail state. If fail state has been returned, then the event must disallow the initially requested action. Lastly, I need to add to the file in question a property or attribute that will contain metadata that will be used by the above event trigger handler program to make a determination as to the pass/fail condition that will ultimately determine if the user is permitted to open the file. Please note that this is NOT a windows event log situation, but one at the OS level file open event. thanks very much for your help. regards, j

  • What is the standard term for my role?

    - by sigil
    I'm doing work that involves writing code and managing developers in a "special projects" division of a large company. I'd like to define my role better and figure out if there's an industry standard term for what I do, so that it will be easier for me to research best practices and work on a career path What I do all day: A macro that connects an Excel sheet to an Access database is acting funny; I get called in to figure out what's happening and debug it. Someone needs data extracted from a bunch of files on Sharepoint. I figure out a client-side solution because I'm not authorized to do anything server-side and getting IT to do anything would take several months and need a business case. A manager wants a new data entry tool for their team. I interview the manager and team members to work out the functional requirements, then design/develop/test the application. Someone needs a VBA script to crunch some data for their presentation that's due in two hours. I drop everything I'm doing to hack out a quick script and run the analysis, without much in the way of testing. A developer has been hired to build a database for one of the teams, since I'm working on too many different things and don't have time to take this project on in the timeframe required. I direct his work and push him to meet certain deadlines, interview stakeholders to get more info that will help him figure out how to build the necessary forms, and modify the functional requirements of the database to fit in the timeframe. Someone wants to load a set of data into a GIS system and set up an ongoing refresh and reporting of this data set. I facilitate the conversation between the GIS developers and the owners of this data set, and design a demo application as proof of concept. It's kind of an "all-purpose programming and IT management" position, but it's not officially IT because the company has an actual IT department with a rigorously defined system of submitting requests, developing code, and managing projects. What I do, I guess, is more of a handyman job, where stuff falls to me because I'm the geekiest one in the room. Is there a standard term in the software world for what I do?
