• R: getting "inside" environments

  - by Mike Dewar

  Given an environment object e: > e <environment: 0x10f0a6e98> > class(e) [1] "environment" How do you access the variables inside the environment? Just in case you're curious, I have found myself with this environment object. I didn't make it, a package in Bioconductor made it. You can make it, too, using these commands: library('GEOquery') eset <- getGEO("GSE4142")[[1]] e <- assayData(eset)

• Theory: Can JIT Compiler be used to parse the whole program first, then execute later?

  - by unknownthreat

  Normally, JIT Compiler works by reads the byte code, translate it into machine code, and execute it. This is what I understand, but in theory, is it possible to make the JIT Compiler parses the whole program first, then execute the program later as machine code? I do not know how JIT Compiler works technically and exactly, so I don't know any feasibility in this case. But theoretically, is it possible? Or am I doing it wrong?

I suspect one solution may lie in this direction.

• Does Hibernate always need a setter when there is a getter?

  - by Marcus

  We have some Hibernate getter methods annotated with both @Column and @Basic. We get an exception if we don't have the corresponding setter. Why is this? In our case we are deriving the value returned from the getter (to get stored in the DB) and the setter has no functional purpose. So we just have an empty method to get around the error condition..

• Supress title of listings created with the LaTeX listings package

  - by t6d

  I'm using LaTeX in conjunction with the listings package and I'm trying to suppress the title of a listing such that it is neither viewed below the actual listing nor in the list of listings. Setting the option title to title="" or title= does not work. It only leads to the suppression of the listing in the list of listings. However, in the first case "" is displayed below the listing and in the latter one Listing: is displayed below the listing. Is there a way to fix this?

• Why do condition variables sometimes erroneously wake up?

  - by aspo

  I've known for eons that the way you use a condition variable is lock while not task_done wait on condition variable unlock Because sometimes condition variables will spontaneously wake. But I've never understood why that's the case. In the past I've read it's expensive to make a condition variable that doesn't have that behavior, but nothing more than that. So... why do you need to worry about falsely being woken up when waiting on a condition variable?

• Automatically open files given as command line arguments in Python

  - by mk

  I have a lot of Perl scripts that looks something like the following. What it does is that it will automatically open any file given as a command line argument and in this case print the content of that file. If no file is given it will instead read from standard input. while ( <> ) { print $_; } Is there a way to do something similar in Python without having to explicitly open each file?

• QueryString From Shared Function

  - by Kezzer

  I'm trying to get a query string from a shared function in a code-behind model using VB.NET. You have to use HttpContext.Current.Request.QueryString("Query") in order to get it from a shared function, however doing HttpContext.Current.Request.QueryString.Count gives back 0, which obviously isn't right in my case as there's many that exist. Is there some sort of issue with using this static call from a shared function?
