  • Agile development challenges

    - by Bob
    With Scrum / user story / agile development, how does one handle scheduling out-of-sync tasks that are part of a user story? We are a small gaming company working with a few remote consultants who do graphics and audio work. Typically, graphics work should be done at least a week (sometimes 2 weeks) in advance of the code so that it's ready for integration. However, since SCRUM is supposed to focus on user stories, how should I split the stories across iteration so that they still follow the user story model? Ideally, a user story should be completed by all the team members in the same iteration, I feel that splitting them in any way violates the core principle of user story driven development. Also, one front end developer can work at 2X pace of backend developers. However, that throws the scheduling out of sync as well because he is either constantly ahead of them or what we have done is to have him work on tasks that not specific to this iteration just to keep busy. Either way, it's the same issue as above, splitting up user story tasks. If someone can recommend an active Google agile development group that discusses these and other issues, that'll be great. Also, if you know of a free alternative to Pivotal Labs, let me know as well. I'm looking now at Agilo.

  • Windows XP Computer Management - Local Users and Groups error

    - by Wesley
    Hi all, I opened Computer Management and happened to see that "Local Users and Groups" (under System Tools) had a red X over top of it. After clicking the link, it shows a message saying "Unable to access the computer EMACHINES-PC. The error was: Library not registered." What could have caused this, and how can I fix it? Thanks in advance!

  • Looking for a simple Ticket Management Software

    - by waszkiewicz
    I'm looking for a good, free ticket management software that could be accessible from everywhere. The company is small (10 people) and the first goal is to have a database and to follow important incidents, even if someone is out of office. I tried OTRS, very nice but I suppose a bit complicated for some of our developers. Thanks for your suggestions. EDIT: I forgot to write that the platform is Windows for all users.

  • Is there a good, free, online database application?

    - by andygrunt
    Google docs doesn't have a database app (yet) but can anyone point me to a good, free, online substitute? It'll be for simple things like a database of my DVD collection and I'd want to be able to import/export using standard file formats and add/edit fields of existing databses. By the way, I'm not interested in using a spreadsheet as a database.

  • Relationships in a Chen ERD

    - by Nibroc A Rehpotsirhc
    I am working on a Chen ERD to model our organizations merchandise. Our central entity is a Style. We have supplemental entities of Color and Season. I am defining our assortment as the relationship between these three entities, and this relationship itself will have attributes and is defined by the three entities which participate in the mandatory relationship. The rules are; Many Styles can be offered in a Season, and a Style can be offered in many Seasons. Within a Season, a Style can be offered in Many Colors. I then have 2 other entities, one of which I believe is a weak entity, Climate, and the other may be weak, but I am not sure, this being Transaction Channel. I am thinking of these as relationships off of a relationship? Meaning, for a given Style/Color combination offered in a Season, it can be available through 1 or more Transaction Channels. Additionally, within a season, a given Style/Color combination can be intended for 1 or more Climates. Is it valid to have relationships off of relationships? Or does this requirement dictate that I should think of this Style/Color/Season relationship as an entity itself, and define the relationships to Climate and Transaction Channel off of this entity?

  • Why many designs ignore normalization in RDBMS?

    - by Yosi
    I got to see many designs that normalization wasn't the first consideration in decision making phase. In many cases those designs included more than 30 columns, and the main approach was "to put everything in the same place" According to what I remember normalization is one of the first, most important things, so why is it dropped so easily sometimes? Edit: Is it true that good architects and experts choose a denormalized design while non-experienced developers choose the opposite? What are the arguments against starting your design with normalization in mind?

  • DHCP server with database backend

    - by Cory J
    I have been looking around for something to replace my (ancient) ISC-DHCPd server. A DHCP server with a database backend sounds like a great idea to me, as I could then have a nice, friendly web interface to my server. Surprisingly, I can't any major open-source projects that offer this. Does anyone know of one? I have also read about modifying ISC to use a database backend...can anyone tell me if this solution is stable enough for a busy production server? Or is using a database a Bad Idea™ all together? PS - http://stackoverflow.com/questions/893887/dchp-with-database-backend looks like SO couldn't answer this old, similar question. EDIT: I am looking for something on a free OS platform, Linux or BSD. If there is something absolutely great that is Windows-only though, still interested.

  • Web Based Project Management System

    We are very well aware about the software development life cycle and project management system. But many of the developers assume that it is available only as desktop application. But now a days there are many online web based project management tools are available in market. In this article I am providing information about what is web based project management system, the available open source web based PMS and the benefits of using web based project management system for business owners.

  • How do I duplicate a server's packages and configuration to another machine?

    - by sharjeel
    I have a production server running Ubuntu. I would like to setup similar configuration installed on my local machine. I'd like to have same packages installed. Since bandwidth is a constraint the traditional disk cloning methods won't work for me. Having same packages installed and same users with same passwords created would be wonderful; i'll tweak rest of the things manually. Is there a good solution to my requirements?

  • Is it normal for programmer to work on multiple projects simultaneously.

    - by gasan
    On a current job I have 2 projects to work on. First is very huge system and the second one is smaller but it also big (first project is being developed for 12 years, second for 4 years). At first I was working only on first project and was trying to get used to it. Then I was moved to second project and tried there, so my knowledge about first project became shady. Now I have to work on both projects at the same time. It's very hard for me because despite they both use java, they use different frameworks and the amount of code and business-logic to understand is very big so I really can't hold both that projects in my head. Is it normal and I should get used to it, although my expertise became very squashy, what won't happen if I would work only on a single project? Or should I raise a concern or maybe change employer?

  • Problem with creating table on phpMyAdmin database

    - by tombull89
    Hello all, I'm running a phpMyAdmin Database on my web package on a 1and1-hosted server. I've managed to set up a database in the control panel, have uploaded all to root/phpmyadmin and changed the config.ini.php file to point at 1and1's database server (because that's the way they do it). I can go to the web interface and get to the main page, but all it shows is the database name and I can't find how to create any tables. I know it's a long shot but I'm almost out of ideas. Also, 1and1 have their own phpmyadmin panel, which is pretty annoying to use, and a 1and1 webdatabase which I have barely looked at. Help and suggestions much appriciated.

  • How do you update live web sites with code changes?

    - by Aaron Anodide
    I know this is a very basic question. If someone could humor me and tell me how they would handle this, I'd be greatful. I decided to post this because I am about to install SynchToy to remedy the issue below, and I feel a bit unprofessional using a "Toy" but I can't think of a better way. Many times I find when I am in this situation, I am missing some painfully obvious way to do things - this comes from being the only developer in the company. ASP.NET web application developed on my computer at work Solution has 2 projects: Website (files) WebsiteLib (C#/dll) Using a Git repository Deployed on a GoGrid 2008R2 web server Deployment: Make code changes. Push to Git. Remote desktop to server. Pull from Git. Overwrite the live files by dragging/dropping with windows explorer. In Step 5 I delete all the files from the website root.. this can't be a good thing to do. That's why I am about to install SynchToy... UPDATE: THANKS for all the useful responses. I can't pick which one to mark answer - between using a web deployment - it looks like I have several useful suggesitons: Web Project = whole site packaged into a single DLL - downside for me I can't push simple updates - being a lone developer in a company of 50, this remains something that is simpler at times. Pulling straight from SCM into web root of site - i originally didn't do this out of fear that my SCM hidden directory might end up being exposed, but the answers here helped me get over that (although i still don't like having one more thing to worry about forgetting to make sure is still true over time) Using a web farm, and systematically deploying to nodes - this is the ideal solution for zero downtime, which is actually something I care about since the site is essentially a real time revenue source for my company - i might have a hard time convincing them to double the cost of the servers though. -- finally, the re-enforcement of the basic principal that there needs to be a single click deployment for the site OR ELSE THERE SOMETHING WRONG is probably the most useful thing I got out of the answers. UPDATE 2: I thought I come back to this and update with the actual solution that's been in place for many months now and is working perfectly (for my single web server solution). The process I use is: Make code changes Push to Git Remote desktop to server Pull from Git Run the following batch script: cd C:\Users\Administrator %systemroot%\system32\inetsrv\appcmd.exe stop site "/site.name:Default Web Site" robocopy Documents\code\da\1\work\Tree\LendingTreeWebSite1 c:\inetpub\wwwroot /E /XF connectionsconfig Web.config %systemroot%\system32\inetsrv\appcmd.exe start site "/site.name:Default Web Site" As you can see this brings the site down, uses robocopy to intelligently copy the files that have changed then brings the site back up. It typically runs in less than 2 seconds. Since peak traffic on this site is about 2 requests per second, missing 4 requests per site update is acceptable. Sine I've gotten more proficient with Git I've found that the first four steps above being a "manual process" is also acceptable, although I'm sure I could roll the whole thing into a single click if I wanted to. The documentation for AppCmd.exe is here. The documentation for Robocopy is here.

  • Keep user and user profile in different tables?

    - by Andrey
    I have seen in a couple of projects that developers prefer to keep essential user info in one table (email/login, password hash, screen name) and rest of the non essential user profile in another (creation date, country, etc). By non-essential I mean that this data is needed only occasionally. Obvious benefit is that if you are using ORM querying less fields is obviously good. But then you can have two entities mapped to same table and this will save you from querying stuff you don't need (while being more convenient). Does anybody know any other advantage of keeping these things in two tables?

  • How can you predict the time it will take for two processes in two different machines in a cluster to communicate?

    - by Dokkat
    I am trying to develop a computing application which needs a lot of memory (500gb). Buying a single machine for that is overly expensive. I can, though, buy ~100 small instances on Digital Ocean or similar, divide the memory in blocks and use TCP to emulate shared memory between the instances. Now, my question is: how can I measure/predict the time it will take for two processes in two different machines like that to share information, in comparison to IPC and shared memory? Are there rules of thumb? I don't want exact values, but knowing more or less how much faster one is would be very helpful in visualising the feasibility of this approach.

    I am designing an application that allow users to highlight areas of a geographical map using a tool that is like brush or a pen. The tool basically draw a circle with a single click and continue drawing those circles with move move. Here is an example of drawing made by moving the tool. It is pretty much same as Microsoft Paint. Regardless of programming language what is best approach (most inexpensive approach) for saving this kind of data?

  • Is it common to only pay developers for the time they said a project would take?

    - by BAM
    I work at a small startup (<10 people), and I was recently assigned (along with one other developer) to a relatively small project. The project involved moving an existing iOS app to Android. The client told us they had built the app for iOS in 300 man-hours. Not knowing at the time that this figure was completely false, we naively and optimistically assumed that if they could build the app from scratch in that amount of time, we could easily "port" it in a similar amount of time. Therefore, we drafted up a fixed-price contract based on 350 man-hours, with a 5 week deadline. (We are well aware now of how big of a mistake this was... Never let the client tell you how long it's going to take!) Anyway, by week 4 we had already surpassed our 350 hours, and we estimated that there were at least 2 more weeks left on the project. We were told to continue working, but that the company could not afford to pay out on overdue projects anymore. I thought this just meant "be more careful about estimates in the future". However a few weeks later, the company president informed us that we would not be getting paid for any time past 350 man-hours. We argued over the issue for almost an hour. He claimed, however, that this is standard practice for many organizations, and that I was unreasonable for making a big deal out of it. So is this really a common thing, or am I justified in being upset about it? Thanks in advance for any advice!

  • Implementing new required feature after software release

    - by TiagoBrenck
    Fake Scenario There is a software that was released 1 year ago. The software is to map and register all kind of animals on our planet. When the software was released, the client only needed to know the scientific name of the animal, a flag if it is in risk of extinction and a scale of dangerous(that is a fake software and specification, I don't want to discuss this here). There are already 100.000 animals records saved on DB. New Feature One year later, the client wants a new feature. It is really important to him to know the animals classes, and this is a required field. So he asks me to put a field to input the animal class, and this field is required. Or maybe where this animal was discovered. Problem I have already 100.000 recorded animals without a class or where it was discovered, but I need to insert a new column to storage this information and this column can't be null. I don't have a default value for this situation (there isn't a default animal class or where it was discovered). I don't want to keep the requirement rule only on my software, my DB must have this requirement too(I like to keep business rules on DB too). What are the alternatives to solve this situation? I am on a situation that this new feature cannot be previewed or reviewed for the existing records. The time already passed and I can't go back on time to get it

  • Handling deleted users - separate or same table?

    - by Alan Beats
    The scenario is that I've got an expanding set of users, and as time goes by, users will cancel their accounts which we currently mark as 'deleted' (with a flag) in the same table. If users with the same email address (that's how users log in) wish to create a new account, they can signup again, but a NEW account is created. (We have unique ids for every account, so email addresses can be duplicated amongst live and deleted ones). What I've noticed is that all across our system, in the normal course of things we constantly query the users table checking the user is not deleted, whereas what I'm thinking is that we dont need to do that at all...! [Clarification1: by 'constantly querying', I meant that we have queries which are like: '... FROM users WHERE isdeleted="0" AND ...'. For example, we may need to fetch all users registered for all meetings on a particular date, so in THAT query, we also have FROM users WHERE isdeleted="0" - does this make my point clearer?] (1) continue keeping deleted users in the 'main' users table (2) keep deleted users in a separate table (mostly required for historical book-keeping) What are the pros and cons of either approach?

  • Opening an oracle database crashes the service [SOLVED]

    - by tundal45
    I am experiencing a weird issue with Oracle where the service started fine after a crash. The database mount went fine as well. However, when I issue alter database open; command, the database does not open, gives a generic cannot connect to the database error & crashes the service. Oracle support has not seen this issue before so it's pretty scary. The fact that there are no logs that give any leads as to what could be causing this is also scary. I was wondering if good folks over at Server Fault had seen something like this or have some insights on things that I could try. It's Oracle 10g running on Windows Server 2003. Thanks, Ashish

  • Can you be a programmer and Business manager at the same time?

    - by the_knight5000
    Hello all, I think I'm struggled in some situation! We are a new start-up with 5 employees (2 Programmers). I'm the Technical Manager and that was so fine! Now I can see the fingers point to me to take the control of everything, as I've the big vision of what our organization do and play the role of CEO or General Manager! I want to, but I've no idea if it would be risky to our organization to make such a decision? How would managerial interrupts affect the technical productivity? Any tips or previous experience about such situation would help :) Thanks in advance!

  • De-facto standards for customer information record

    - by maasg
    I'm currently evaluating a potential new project that involves creating a DB for typical customer information (userid, pwd, first & last name, email, adress, telfnr ...). At this point, requirements are only roughly defined. The customer DB is expected in the O(millions) of records. In order to calculate some back-of-the-envelope numbers for DB sizing and evaluate potential DB options & architectures, I'm looking for some de-facto standards for these kind of records. In particular, the std size of every field (first name, last name, address,...) or typical avg for a simple customer record would be great info. With so many e-commerce websites out there, there should be some kind of typical config that can be reused and avoid re-inventing the wheel. Any ideas?

  • Benefits of In-house server management vs outsourcing [closed]

    - by Eric Di Bari
    I've just created a small web-based company. We're planning on using a cloud hosting solution, but don't have the current resources to properly setup and manage the server. As a new company, are there more benefits to bringing someone on-board as part of the organization to manage the server, versus going with a third-party management company? Such as a greater degree of 'ownership' and involvement?
