As the title suggests, I've got a problem I just cant find a solution to. I've googled every possible angle and just cant seem to find a solution to this problem.
Basically, I'm missing 2 Link Types -- Affects and Affected By
All the others are there.
For example if i was to create a new Bug WI go to All Links -> Link To there is no option for Affects or Affected By.
Ive checked the data warehouse and the Work Item Link Type Dimension for the cube in analysis services, and they are in fact not in there.
I've tried everything i cn think of,
Ive also exported the linktypes from one of our development environments (which includes the link types) and imported them back into the production server using witadmin... This did not work,
I'm really lost with this one and there just doesn't seem to be any solutions on google, which i find hard to believe but i've spent the last 4 hours looking.
I would really appreciate it if some one could provide some help on this one, im willing to try anything.
It just seems strange why just these 2 link types would be missing.
We use our own process template which is just an extension to the MSF For Agile Software development v5.0 process template.
Seems the only way to solve this issue is to force TFS to recreate the Tfs_Warehouse database and reprocess the cube..... PROBLEM SOLVED

I'm trying to plan and tracking one project with Jira/Asana/Clickup but I can't find one easy thing that I think It should be essential (just me apparently).
During a project things happens, for example an employee might be on vacation, a bug is come up and so on.
So, I'd like to add a note about these events and see them directly on the timeline.
I've found Runn.io but nevertheless it has what I want, it's very scarce about tasks and project managing.
I've tried any kind of Project Management SAAS but It seems none of them have what I need.
Surely there is something I'm wrong with how a process of project has to be tracked, but I think this feature is pretty useful.
Do you have any suggestion please? I'm freaking out.
Thank you
Similar questions has been asked more than 10 years ago. I have tried to search the web for the last two days, and read numerous pages all over the place. Unfortunately, I am still not finding a good answer.
This question should not have been tied to any particular database, but my particular server is mysql 5.6.12. I tried mysql-workbench, and it could not generate the links between the entities even though my database has clear foreign key constraints defined.
In the past I have used a program from Sybase, and it worked fine and need to pay.
I have seen one from Oracle, not sure this one is good or not. It might be a time for people to share experiences here.
I have seen a pattern that usually people who has no problems won't visit this site. Just to make a simple answer to my own question.
Mysql-workbench can display relationships, but if you have one single error in the schema, then not a single one will show up. I found DbSchema a better alternative, and it is not expensive.
I've seen interesting projects on sourceforge:
schemacrawler --> http://schemacrawler.sourceforge.net/
schemaspy --> http://schemaspy.sourceforge.net/
I've never used them but they looks good with maven integration, programatically and command line modes, and many other stuff.
I'm developing an app (basically an intranet) which has a few small sets of users, each a company using the app internally.
Up to now, each set of users has its own deployment with a separate domain name and database, but all living on the same server. This means that each time I have to push an upgrade I need to deploy once per client. Also, each new client means adding a new deploy target, for which I'm currently using Capistrano's multistage plugin, but it's getting a bit ridiculous.
This is a less than ideal setup, so after some thought I came up with the idea of modifying the app so that it handles multiple domains, each mapped to a different database, but on a single deployment. I created a small proof-of-concept app which basically has a before_filter in ApplicationController acting as a multiplexer for domains/databases, connecting ActiveRecord to each domain's database on each request. This worked really well, but I haven't applied this to the big app yet and I can think of at least one problem down the road: running migrations across all databases. I'm pretty sure I can work around that one though, maybe I'll tweak the rake task a little, but I'm worried that might not be the last of problems with it.
Has anyone ever tried this, or can think of any major reasons why this would be a bad idea? I would like to listen to some opinions.
Thanks!
This is usually called multi-tenancy. Here is a presentation or video about doing it in rails. Couldn't tell if it was any good, it was blocked here at work.
And no, there is nothing wrong with it as an idea. I'm not sure about your particular implementation, but I have worked on apps that were multi-tenant in the past and can't say we ever had much difficulty except when trouble clients wanted to stay on a legacy version of the product and we wanted to move forward.
I have a similar app and still the same problem as you, and after many tries, i ended up (before a desirable core solution came) with one env file per domain and kind a filter like yours.
I've been running in production for almost 1 year, and the only problem i detected is that rails expected the main db (even you won't use it) to have the same migration level as the others. (this problem arise under certain conditions)
If you need futher details, just let me know.
I hope this helps.
There is Ruby on Rails (1.8, 2.3.2) project. First version of project was made by some organisation. I will implement next versions of this project without any help from this organisation. I will be able to talk with developers from previous development team during meeting (1-3 hours).
Project statistics: ~10k LOC, 1.0/0.6 code to test ratio, rspec
What questions about project can you recommend to ask?
First review the entire project and to figure out as much as possible so you have context and can actually understand what they tell you.
Ask
If you can record the conversation
For an architectural overview
Why they made certain architectural decisions over another
A complete list of dependencies (if you can't figure that out on your own)
What the biggest problems are
Which parts of the projects are always / never being fixed
What the Achilles' Heel of the project is
What will cause the biggest headaches
What security issues are there and what the constraint is to fixing it
What would you do next if you were me?
What you should know that you didn't ask (most important question)
Also, don't be judgemental, you want them to reveal any problems they know about. There are probably tons of things wrong with the app that they are embarassed about, which you need to know sooner rather than later. They're not going to open up to you if they don't trust you.
I would ask for a code walkthrough. Not line-by-line, but more for the overall structure of the project, relationships between individual modules, etc.
Find out the Why's. How is easy enough to see in the codebase, but the why is sometimes impossible to figure out, and will bite you in the ass.
For instance...
Which parts of the application were the biggest performance issues? Which of those issues were resolved? Which are still issues?
Why did you opt for pattern / tool / library x? What other things did you consider? Why?
This will hopefully. (Hit some wood.) Help keep you from having to trudge through the same learning curve and mistakes that the first team had to deal with, and should give you good insight into where the first team actually made a poor choice, instead of making a choice based on factors you have not accounted for yet.
Ask if the new features will cause any major changes to the existing code (architecturally) and what the implication of that will be with other dependent parts of the application.
Also get their emails, as you will have more questions.
One of the most important things, in my opinion, is to get as much technical documentation as you can prior to meeting with them. You should try to go into the meeting as informed as possible, so that you not only know what areas you need to focus on the most, but also to have a preexisting knowledge of how some of the subsystems relate to each other.
Also, do not be afraid to ask what they would have done differently, if given the chance. Some of the best ideas come too late in the development process to be implemented - be it from library availability, change in requirements, change in team, etc.
Bring cookies (or pizza, beer, or wine as appropriate); you will want them to have positive memories of you for when you call with questions.
Edit: to put my answer in the form of a question: "May I offer you a home-baked cookie?"
Perhaps you have done this already, but I would make sure you can:
Checkout the latest version
Run all the migrations
Run all the tests
Deploy (even if to a staging server)
Run the application locally
Before you go to the meeting, so you can make sure you can by the time it is over.
Other things that might be useful
data model
UI wireframes
bug tracker data / issue tracker data
who are the customers / people representing customers
development environment configuration
source control locations, etc.
explanation of special configuration settings
Wow! All great answers, right down to the cookies.
My contribution assumes that this is your one and only chance to access the old dev team, therefore you need to kick it up a notch:
Agenda. Split the meeting into several parts, for instance:
A quick (15 min) introduction and arch overview
One on one with team members.
Design review as a group, etc.
Positive Energy. Especially if the relationship is inherently difficult, keep a positive focus by postulating: what improvements would you put into the next version - (rewrite is not an option, right Joel) - capture every nuance, and drill down past their comfort level only nearer the end.
Facilitator. Use a trained design meeting facilitator. They can help prep for the meeting, conduct pre-meeting interviews, design the agenda. During the meeting they can drive the intensity, and keep the focus. They can also suggest forms of capturing what can be a fair amount of information.
Also, I would try to id all design artifacts beyond the code, if any, and come to an understanding of how accurate it is. This may include doing design reviews of key elements of these documents vis a vis the as-built system.

I recently joined a new company with a large existing codebase. Most of my experience has been in developing small-medium sized apps which I was involved with since the beginning.
Does anyone have any useful tools or advice on how to begin working on a large app?
Do I start at the models and move to controllers? Are there scripts to visually map out model relationships? Should I jump in, start working on it and learn the apps structure as I go?
Railroad should help you understand the big picture. It generates diagrams for your models and controllers.
I found unit tests to be the most efficient, effective and powerful tool. So, before making any change, make sure your application has a minimum LOC so that you won't break any existing feature working on.
You should care about unit tests (of course I'm talking about unit/functional/integrational tests) because:
they ensure you won't break any existing feature
they describe the code so that you won't need tons of comments everywhere to understand why that code fragment acts in that way
having test you'll spent less time debugging and more time coding
When you have tests, you can start refactoring your app.
Here's a list of some tools I usually work with:
Rack::Bug
New Relic
You might want to view some of the wonderful Gregg's videos about Scaling Rails to get more powerful tools.
Also, don't forget to immediately start tracking how your application is performing and whether it is raising exceptions. You can use one of the following tools
Hoptoad
Exceptional
If you need to fix some bug, don't forget to reproduce the issue with a test first, then fix the bug.
Not specific on Rails, but I would start reading the requirements and architecture documentation. After that get familiar with the domain by sketching the models and their relationship on a big sheet of paper.
Then move on to the controllers (maybe look at the routes first).
The views should not contain that much information, I guess you can pretty much skip them.
If you still need to know more, the log of the versioning system (given they use one) is also a good place to get to know how the project evolved.
When I've been in this situation, I try one of three things:
Read all the code top to bottom. This lets you see what code is working, and you can report progress easily (I read through all the view code this week). This means you spend time on things that may not be helpful (unused code) but you get a taste of everything that is there. This is very boring.
Start at the beginning and go to the end. From the login page or splash screen, start looking at that code, then the next page, then the next page. Look at the view, controller, and database code. This takes some time, but it gives you the context for why you need that code or database table. And it allows you do see most often the ones that get used in the most places. This is more interesting.
Start fixing bugs. This has the benefit of showing progress on your new project (happy boss) taking work from other people (happy co-workers) and learning at the same time (happy developer). It provides the context of number 2, and you can skip rarely used code from number 1. This is the most interesting way for me.
Also, keep track of what you've learned. Get a cheap spiral-bound notebook and write down an outline of what you've learned. Imagine yourself giving a talk on the code you're learning about or bug you're fixing. Take enough notes to give that talk, and spice it up with a factoid or two to make it interesting. I give my notebooks dignity and purpose by calling them "Engineering Notebooks", put a title on the front (my name, company, date), and bringing them to every meeting. It looks very professional compared to the guys who don't show up with paper to take notes. For this, don't use a wiki. It can't be relied upon, and I spend a week playing with the wiki instead of learning.
As mentioned above, being the new guy is a good chance to do the things nobody ever got around to like unit tests, documenting processes, or automating running tests. Document the process to set up a new box and get all the software installed to be productive. Take an old box under someone's desk and put a continuous integration install on it, and have it email you when the tests fail. You can forward that email whenever someone else checks in code that breaks the tests. Start writing tests to figure out how things work together, esp. if there aren't any/very many tests.
Try to ask lots of questions in one-on-one situations. This shows you're engaged and learning, and it helps you find the experts in the different parts of the app. On a big project you may need to go to one person for one topic and a different person for other topics. It also helps identify who thinks they know more than they really do or who talks more than you really need.
