• Passing Request Object into Service Layer

  - by SpringTrickery

  In a spring mvc + spring core app, we have have a view layers, a facade, a service layer, a dao layer and a stored-proc based persistance layer. The service layer is unaware of the clients that utilitize its methods. Is it fine to propagate raw http requests into the service layer? Or is it bad practice and a violation of the loose coupling principles? If it is, then what's a clean workaround?

Do I need to programmatically edit the .bashrc file, adding the appropriate entries to the end for example, or is there another way? What's standard practice? Thanks

• javascript string difference

  - by Konrad

  What is the difference (if any) between the javascript strings defined below? var str1 = "Somestring"; var str2 = 'Somestring'; "" and '' mean two very different things to me predominantly writing code in C++ :-) EDIT: If there is no difference why are there two ways of achieving the same thing and which is considered better practice to use and why. Thanks!

• Both OpenID and normal Login on the same View?

  - by PlayKid

  Hi there, Is there any site that show both OpenID and normal login on the same view? Most of the sites either have OpenID implementation or Normal Login implementation on different views. I tried to do that, but it seems my code is very dirty, passing a blank username and password if using OpenID, otherwise OpenID will be blank but passed the username and password. But then I lose the capability of verifying whether the user has entered the correct values, is there any best practice for me to do that? Thanks a lot

• Am I supposed to store hashes for passwords?

  - by Doug

  User System and Passwords: I was looking through MD5 stuff, and I am wondering what is the normal/good practice for passwords. Right now, I think people super encrypt the passwords and store the hashes. If so, how does password checking work? I just have the input password go through the encryption process again and then check the hash with the stored one, correct? This question may contradict the above, but should my salt ever be a randomly generated value?

• Web hosting a setup where both Windows and Linux are required

  - by lk

  I have a system where a website needs to be hosted on a Linux machine while a backend application that the site talks to needs to reside on Windows. Is there any "common practice" for such hosting? Note - both of the systems are mine so there is the dilemma of whether to have the machines physically located together to avoid delay for calls over the net.

• When should I implement IDisposeable?

  - by Bobby

  What is the best practice for when to implement IDisposeable? Is the best rule of thumb to implement it if you have one managed object in the class, or does it depend if the object was created in the class or just passed in? Should I also do it for classes with no managed objects at all?

• Copying subversion commit messages

  - by Falcor

  I know this isn't the BEST practice, but every once in a while when I'm merging up a huge batch up changes with the trunk (and I know my branch is current), I will simply delete the contents of the trunk and then copy the contents of my branch up, so that I don't have to deal with resolving conflicts for an hour. The problem is that I seem to lose the entire history of commit messages for each file. My branch still has the correct history of commit messages... how can I merge them up?

• Metaprogramming on web server

  - by bobobobo

  From time to time, I find myself writing server code that produces JavaScript code as the output result. I can point out why it is really bad: Inextricable tie between server code and client code. Can render client code un-reusable. But sometimes, it just seems to make sense. And isn't it kinda sorta interesting? I guess the question is, is writing server code that produces JavaScript code a really bad practice, or "does everyone do it"?

• (android) rows of buttons that take up the entire width of the screen

  - by user558043

  I am trying to make 3 rows of 4 buttons each that will take up the entire width of the screen. I have tried Linear Layout but have trouble adding a second row and from what I have read nesting Linear Layouts is bad practice. I tried to use relative layout several times but I cannot manage to get the buttons to fill the width of the screen because it ignores layout_weight, I then tried nesting linear layout in relative layout but layout_weight is still ignored. What is the best way to accomplish this?
