unhappy with MySQL workbench 5.2 - mysql-workbench

Is there a better option for windows out there?
I come froma MS SQL-Server environment so something that's similar to their editor would probably be most preferable.

What capabilities are you looking for.
MySQL Workbench evolves really quick and the 5.3 should be out fairly soon.
I don't think there's anything comparatively good unless you simply use phpmyadmin...
The 5.3 should be out soon with its load of fixed bugs.
What don't you like with it. Maybe I can help if I understand.

I don't think there's a better option for you if you have to work with MySQL.
I agree with you: MySQL Workbench generally could behave much better; some operations simply produce no output leaving you wondering what happened. If you're used to Microsoft SQL Server, you'll likely miss the capability to run several queries in one code editor window, producing several outputs at the same time. This is the biggest usability drawback, in my opinion.
There are some things MySQL does better though, so it's a mixed bag.

Julia 0.6 to Postgres connection - Available options and LibPq.jl

I was with Julia 0.5 and used PostgreSql.jl to connect to the Database. It internally uses DBI.jl dependency.
Now upgrading to version 0.6, this has stopped working. The only alternative I could find online is LibPQ.jl. However, the library is a huge inconvenience to use.
Does anyone here have experience with connecting to Postgres from Julia? How did you achieve it?
Please shoot any questions if I have missed giving any information.
I achieved it by writing and using PostgreSQL.jl, and later LibPQ.jl. PostgreSQL.jl was very much a novice effort, and I stand by LibPQ.jl as the better option. Briefly in development we used ODBC.jl, but found that difficult to configure, inflexible in output, and slow. Using LibPQ.jl has simplified our database interaction code and improved transfer speeds.
I found it more useful to write a package that supported an existing general data interface (DataStreams.jl) than to write and maintain a database interface that I wasn't personally invested in. There's certainly opportunity to do so, and to support the interface using LibPQ.jl, but it is no longer a personal goal of mine.
I am also happy to discuss any inconvenience you have using LibPQ.jl in an appropriate forum (tagging me on the JuliaLang Discourse site always gets a response).

NHibernate,Entity Model or LightSpeed which is preferable?

Can any one tell which is best suited for performance oriented applications?
All of the above. Or none of the above. No way to tell without measuring performance and seeing which one does or does not work for you.
I would agree with the existing answers here: Understand what performance really means to your application before going off half-cocked on something (most of us have been there). If you're looking for something super-performant but that still has some "ORMish" behavior and takes some monkey coding out of the ADO.Net equation, take a look at the various .Net MicroOrms out there such as:
Dapper (with extensions)
Service Stack's ORM Lite
Insight.Database
Massive
There are several others out there, some of which are referenced from the dapper site.
If you really are stuck with those three choices, it definitely does depend on a lot of factors and how much time you spend tuning. That being said, I've used all three quite a bit, especially NHib 2-3 and EF 4-6. I think if you are doing just quick-and-dirty coding without spending a lot of time on optimizing, LightSpeed is a really good choice and I've personally found it to outperform the other two very handily when it comes to most basic CRUD operations and LINQ queries.
The big downside of LightSpeed is that you have to inherit from their base classes. This is somewhat mitigated by partial class support and you can also insert your own base classes in between, and there's also no true "CodeFirst" support, although you can handcode the classes and skip the designer if you like. They all work well if tuned properly. Just pick the right tool for the job.
Whichever you chose, use your SQL Profiler / Mini Profiler / NHProf / EFProf etc...

Is there any good code analysis/refactoring tools for T-SQL besides RedGate?

I've used RedGate in the past, but the feature-to-price ratio really sucks. At $369 for one-year it is far too expensive when compated to much richer applications like CodeRush and Resharper.

Are there any medium-sized web applications built with CGI::Application that are open-sourced?

I learn best by taking apart something that already does something and figuring out why decisions were made in which manner.
Recently I've started working with Perl's CGI::Application framework, but found i don't really get along well with the documentation (too little information on how to best structure an application with it). There are some examples of small applications on the cgi-app website, but they're mostly structured such that they demonstrate a small feature, but contain mostly of code that one would never actually use in production. Other examples are massively huge and would require way too much time to dig through. And most of them are just stuff that runs on cgiapp, but isn't open source.
As such I am looking for something that has most base functionality like user logins, db access, some processing, etc.; is actually used for something but not so big that it would take hours to even set them up.
Does something like that exist or am i out of luck?
CGI::Application tends to be used for small, rapid-development web applications (much like Dancer, Maypole and other related modules). I haven't seen any real examples of open-source web apps built on top of it, though perhaps I'm not looking hard enough.
You could look at Catalyst. The wiki has a list of Catalyst-powered software and there are a large number of apps there - poke around, see if you like the look of the framework. Of this, this is Perl, so some of those apps will be using Template::Toolkit, some will use HTML::Mason... still, you'll get a general idea.
Try looking at Miril CMS. Although I don't know in which state it is.
I am the same with code, and had the same request. When I did not find a solution I created my own. which is https://github.com/alexxroche/Notice
I hope that it is a good solution to this request.
Notice demonstrates:
CGI::Application
CGI::Application::Plugin::ConfigAuto
CGI::Application::Plugin::AutoRunmode
CGI::Application::Plugin::DBH
CGI::Application::Plugin::Session;
CGI::Application::Plugin::Authentication
CGI::Application::Plugin::Redirect
CGI::Application::Plugin::DBIC::Schema
CGI::Application::Plugin::Forward
CGI::Application::Plugin::TT
It comes with an example mysql schema, but because of DBIC::Schema it can be used with PostgreSQL, (or anything else that DBIx::Class supports.)
I use Notice in all of my real life applications since 2007. The version in github is everything except the branding and the content.

Derby vs PostgreSql Performance Comparison

We are doing research right now on whether to switch our postgresql db to an embedded Derby db. Both would be using glassfish 3 for our data layer. Anybody have any opinions or knowledge that could help us decide?
Thanks!
edit: we are writing some performance tests ourselves right now. Looking for answers more based on experience / first hand knowledge
I know I'm late to post an answer here, but I want to make sure nobody makes the mistake of using Derby over any production-quality database in the future. I apologize in advance for how negative this answer is - I'm trying to capture an entire engineering team's ill feelings in a brief Q&A answer.
Our experience using Derby in many small-ish customer deployments has led us to seriously doubt how useful it is for anything but test environments. Some problems we've had:
Deadlocks caused by lock escalations - this is the biggest one and happens to one customer about once every week or two
Interrupted I/Os cause Derby to fail outright on Solaris (may not be an issue on other platforms) - we had to build a shim to protect it from these failures
Can't handle complicated queries which MySQL/PostgreSQL would handle with ease
Buggy transaction log implementation caused a table corruption which required us to export the database and then re-import it (couldn't just drop the corrupted table), and we still lost the table in the process - thank goodness we had a backup
No LIMIT syntax
Low performance for complicated queries
Low performance for large datasets
Due to the fact that it's embedded, Derby is more of a competitor to SQLite than it is to PostgreSQL, which is an extremely mature production-quality database which is used to store multi-petabyte datasets by some of the largest websites in the world. If you want to be ready for growth and don't want to get caught debugging someone else's database code, I would recommend not using Derby. I don't have any experience with SQLite, but I can't imagine it being much less reliable than Derby has been for us and still being as popular as it is.
In fact, we're in the process of porting to PostgreSQL now.
Derby still is relatively slow in performance, but ... where ever your Java application goes your database server goes, completely platform independent. You don't even need to think about installing a DB server where your Java app is being copied to.
I was using MySQL with Java, but having an embedded implementation of your Database server sitting right within my Java App is just stunning and unprecedented productivity, freedom and flexibility.
Always having a DB server included whenever and wherever on any platform for me is just heaven !!!
Have not compared Postgresql to Derby directly. However, having used both in different circumstances, I have found Derby to be highly reliable. However you will need to pay attention to Derby configuration to ensure it suits your application needs.
When looking at the H2 databases stats site, it's worth reading follow up discussion which comes out in favour of Derby compared to the H2 conclusions. http://groups.google.com/group/h2-database/browse_thread/thread/55a7558563248148?pli=1
Some stats from the H2 database site here:
http://www.h2database.com/html/performance.html
There are a number of performance test suites that are included as part of the Derby source code distribution itself; they are used by Derby developers to conduct their own performance testing of Derby. So if you need examples of performance tests, or want additional ones, you could consider using those. Look in the subdirectory named java/testing/org/apache/derbyTesting/perf in the Derby source distribution.
I'm not sure what you mean that Derby is embedded. Certainly that is an option, but you can also install it as a separate server.
