• How to disconnect an existing ruby sequel connection to a database?

  - by MG

  I mean the one which was previously established as DB = Sequel.sqlite('my_blog.db') or DB = Sequel.connect('postgres://user:password@localhost/my_db') or DB = Sequel.postgres('my_db', :user => 'user', :password => 'password', :host => 'localhost') or etcetera. The Sequel::Database class has no public instance method called "disconnect" or so though it has "connect" one. Maybe somebody already faced that problem. I would appreciate any idea.

• Visual Studio 2010 - Is it slow for anyone else?

  - by AngryHacker

  I've read a lot of stuff about VS2010 being much more performant than VS2008. When I've finally installed it, I found that it, in fact, is much slower (save for the Add References dialog). For instance, Silverlight projects take twice as long to load, the startup of the IDE itself is much slower, etc... Am I missing something here or is it like this for everyone?

• Is Microsoft Workflow Foundation really used ?

  - by ereOn

  Today, I had a training on "Microsoft Workflow Foundation". While I think the idea is neat, I still see it as a Proof Of Concept and not as a real-life solution. Building an entire application without having to type a single line of code (or only a few of them) seems just wrong. Have you ever used this technology and if so, can it really fit to big company projects ? What drawbacks/advantages have you got using it ?

• creating proxy object in groovy

  - by IttayD

  Hi, I am looking for how to write a method that accepts some value and returns a proxy to that value where the underlying value can be retrieved with an accessor: def p = toProxy(1) assert p == 1 assert p * 2 == 2 assert p.underlying == 1 def p2 = toProxy(objWithMethodFoo) p2.foo() p2.underlying.foo() I want to do this per object instance (not for all objects of some class) and without the need to use special 'use' constructs.

• Java, user input to the command line when using Runtime.getRuntime().exec(command);

  - by user1557354

  I dont think this is possible, but I have been using: Process p = Runtime.getRuntime().exec(command); to run commands on the command line, but now I have come accross a situation where the command I am running part way through will ask for some user input, for example a username. This can not be resolved by a argument to the command that is being exec, is there any way I can pass the username to the same command line instance and continue? Thanks in advance.

• How do I get intellisense to pop up?

  - by TheLearner

  How do I get intellisense to pop up while I am coding? I know it pops up when I start typing a known type e.g.: if I type NSS it will finish it for me NSString. How do I get it to give me a bunch of options like in Visual Studio e.g.: if I type NS I want to see what my options are like NSString, NSInteger etc? And if I have not typed anything I still want a bunch of options like all the instance variables etc.

• Using functions and environments

  - by Eduardo Leoni

  Following the recent discussions here (e.g. 1, 2 ) I am now using environments in some of my code. My question is, how do I create functions that modify environments according to its arguments? For example: y <- new.env() with(y, x <- 1) f <- function(env,z) { with(env, x+z) } f(y,z=1) throws Error in eval(expr, envir, enclos) : object 'z' not found I am using environments to keep concurrently two sets of simulations apart (without refactoring my code, which I wrote for a single set of experiments).

• Mod_rewrite on all website images

  - by Esteve Camps

  I'm designing an image repository. I want to uncouple the filename from the image html link. For instance: image in filesystem is called images/items/12543.jpg HTML is <img src="images/car.jpg" /> Does anyone strongly discourages me to rewrite all image requests using PHP so when retrieving images/car.jpg, Apache really replies content from images/items/12543.jpg? I don't know if I may get performance problems.

• How to call a prototyped function from within the prototyped "class"?

  - by Jorge

  function FakeClass(){}; FakeClass.prototype.someMethod = function(){}; FakeClass.prototype.otherMethod = function(){ //need to call someMethod() here. } I need to call someMethod from otherMethod, but apparently it doesn't work. If i build it as a single function (not prototyped), i can call it, but calling a prototyped does not work. How can i do it as if i was treating the function just like a class method?

• What's the quickest way to dump & load a MySQL InnoDB database using mysqldump?

  - by Josh Schwartzman

  I would like to create a copy of a database with approximately 40 InnoDB tables and around 1.5GB of data with mysqldump and MySQL 5.1. What are the best parameters (ie: --single-transaction) that will result in the quickest dump and load of the data? As well, when loading the data into the second DB, is it quicker to: 1) pipe the results directly to the second MySQL server instance and use the --compress option or 2) load it from a text file (ie: mysql < my_sql_dump.sql)

• SQL CONNECTION best Practices

  - by george9170

  Currently there is discussion as to what are the pros and cons of having a single sql connection architecture. To elaborate what we are discussing is, at application creation open a sql connection and at application close or error closing the sql connection. And not creating another connection at all, but using just that one to talk with the DB. We are wondering what the community thinks.

  In one of my forms I use the rich text editor from Yahoo!. Now i want to store the data from that textarea in a MySQL database.

Normally we store by adding that data in one variable and then put that in sql, but the quotes cause problems.

• C# - Does foreach() iterate by reference?

  - by sharkin

  Consider this: List<MyClass> obj_list = get_the_list(); foreach( MyClass obj in obj_list ) { obj.property = 42; } Is 'obj' a reference to the corresponding object within the list so that when I change the property the change will persist in the object instance once constructed somewhere?
