My company's user naming schema changed and we like to apply the new naming schema on our existing Trac instance. We already added the new users, so new tickets and changes will use the new names. What's left to do is to migrate the user names for existing tickets and changes so our existing reports and statistics remain useful.
We are using trac 0.12 with sqlite as database. In principle it should be enough to take a look at the Trac database schema, find all tables with fields containing user names and issue SQL update statements. Still it probably takes a couple of hours to get everything right, so I'd rather use an existing tool than write something from scratch.
Any recommendations?
(We also need to change the user names in our Subversion repository. svndumptool seems to solve this using svndumptool transform-revprop svn:author oldname newname repo.dump newrepo.dump.)
The best place to look for tools like this is a website called Track Hacks. A quick search there turned up three potential solutions for renaming users.

I hope that one of these can help you out.

I am planning to create Login Form for my system. Is it better to use ASP.NET built in Authentication and role management OR create my own way? Which is better and convenient? I want the administrator (Group of people) to be allowed to create users and assign roles to that specific user. Is it possible..? Maybe the question is silly but appreciate your help.
Do NOT create your own authentication system!
Authentication is one of those things where it's easy to build something that seems to work — even passes a rigorous set of unit tests — but is actually flawed in subtle ways that you won't find out about until six months after you get hacked.
The best thing to do is lean as much as possible on the authentication features provided by your platform of choice. If the platform doesn't already provide something suitable, find an existing third-party option that is suitable. What you want is something that is battle-tested; that when a flaw is discovered (there always are some) it's likely because of a break on someone else's system, not your own, and you can just apply the vendor patch to fix it, before your site is really compromised.

I'm try using phpLDAPadmin to connect openldap server, but when I try to create new user account with Generic: User Account, I get the error :
"Template Value Error
This template uses a selection list for attribute [gidNumber], however the selection list is empty.
You may need to create some dependancy entries in your LDAP server so that this attribute renders with values. Alternatively, you may be able to define the appropriate selection values in the template file."
I'm quite newbie with ldap and I had tried to search error related with gidNumber but don't have result, I don't know how to solve it. However, I can using software LdapAdmin to connect server and add new uid acc, and I using Ubuntu Server 13.04 to install ldap server. Hope someone can help me out with it.
Thanks.
You probably just want to create an end user account by selecting the 'Default' option and selecting the inetOrgPerson object class and click the "Proceed" button. On the next screen, you can complete the attribute template to create your entry.
If you really do want a Posix account, first create a Generic: Posix group. After the group is created, the Group ID field will be populated in the Generic User template.
try to make o (organization), ou (organization unit), g (group) then try to make some user.. GID is Group ID, so when GID is empty the template value is error :)

Currently I am doing a restructuring project mainly on the Oracle PL/SQL packages in our company. It involves working on many of the core packages of our company. We never had documentation for the back end work done so far and the intention of this project is to create a new set of APIs based on the current logic in a structured way along with avoiding all unwanted logic that currently exists in the system.
We are also making a new module currently for the main business of the organization that would work based on these newly created back-end APIs.
As I started of this project, I found out that most of the wrapper APIs had around more than 8000 lines of code. I managed to covert this code into many single APIs and invoked them from the wrapper API.
This activity in itself has been a time-consuming process but I was able to cut down the number of lines of code to just 900 in the wrapper API by calling independent APIs for each business functionality.
I would like to know from you experts if this mode of modularizing the code is good and worth the time invested in it as I am not sure if it would have many performance benefits.
But from a code readability perspective, this is definitely helping and now I am able to understand the 8000 lines of code much better after restructuring and I am sure the other developers in my organization too will understand.
Requesting you to let me know if I am doing the right thing and if its having its advantages apart from readability please do mention them. Sorry for the long explanation.
And is it okay having more than 1000 lines of code in a wrapper API.
Easy to debug
Easy to update
Easy to Modify/maintain
Less change proneness due to low coupling.
Increases reuse if the modules are made generic
Can identify unused code easily

I have a project idea for which I want to mine publicly available data on another website that it received by crowd-sourcing. This is so I have initial data for my own project. To reiterate, I want to write a robot to grab data that is displayed on another website and use it for my own website. Does anyone know the legality of this sort of thing? Does the original website own the data that was given to it by a crowd? Even if so, can I use it?
Web scraping is a legally complicated issue.
The hassles of legal action and enforceability often keep scrapers from getting in trouble.
Outright duplication is considered actionable, although courts have ruled that "duplication of facts" is permitted (US).
I advise you read up here: http://en.wikipedia.org/wiki/Web_scraping#Legal_issues
Best,
legally, you should be fine. as long as the data is made available and the people have consented; you aren't hacking and the other site has permission to share. check for a license on the other site, if there isn't one inquire or be prepared for access to be denied at some point. and even though it is publicly available doesn't mean the other site wants it to be.
also, double check and make sure that you don't inadvertently publish private data as well.

Let say that I have a website with some information that could be access externally. Those information need to be only change by the respected client. Example: Google Analytic or WordPress API key. How can I create a system that work like that (no matter the programming language)?
A number of smart people are working on a standard, and it's called OAuth. It already has a number of sample implementations, so it's pretty easy to get started.
Simple:
Generate a key for each user
Deny access for each request without this key
Currently, I use a concatenation of multiple MD5s with a salt. The MD5s are generated off of various concatenations of user data.
A good way of generating a key would be to store a GUID (Globally Unique Identifier) on each user record n the database. GUID is going to be unique and almost impossible to guess.
There are also infrastructure services that manage all this for you like http://www.3scale.net (disclosure I work there), http://www.mashery.com and http://www.apigee.com/.
