    - by kyrisu
    The windows service I am writing will need to run some processor intensive operations once in a while (sound encoding wav - mp3) on a machine that takes part in real time voice communication (so I cannot just run them any-time). What would you check (what counters maybe) before running such operation? Can you point me to any good articles?

  • Faster RSpec with JRuby

    - by jpoz
    Hello, I'm pretty new to the whole JRuby world. I'm using RSpec on a pretty big test suite. I'd like to be able to run the specs frequently but the JVM takes so long to startup it's becoming a real time drain. Is there a way to keep the JVM running? or a way to get specs to run faster with JRuby? Thanks in advance for the help, JPoz

  • Reading binary data from stdin

    - by thebeav
    Is it possible to read stdin as binary data in Python 2.6? If so, how? I see in the Python 3.1 documentation that this is fairly simple, but the facilities for doing this in 2.6 don't seem to be there. If the methods described in 3.1 aren't available, is there a way to close stdin and reopen in in binary mode?

  • R programming function without ()

    - by Mark Kennedy
    So, I Have the following very simple map.r file. I'm trying to have the user type "click" in interactive mode and then have the function . Since it's a function, the user has to type "click()" how can I make it so that they only have to the word (w/o parentheses), and then have that function do something with the img. So the user types: mydist("image.pnm") click //And then the function click does what it's supposed to mydist <- function(mapfile) { img <- read.pnm(mapfile) plot(img) } click <- function() { //Prompt user to click on img }

  • node.js: encrypting data that needs to be decrypted?

    - by fancy
    We are using bcrypt for passwords and data that never needs to be decrypted. What should do to protect other user information that does. For this example lets say that we didn't want a users real name to be in plain text in case someone was to obtain the db. This is somewhat sensitive data but also needs to be called from time to time and displayed in plain text. Is there a simple way to do this?

  • Oracle scheduler job log output

    - by JOTN
    I'm using dbms_scheduler to execute a PL/SQL stored procedure. I would like to be able to have that code create some text logging output and associate it with the run to verify it's working, but I can't find anything to do that in the docs. Is there a facility to do this that I'm missing? This is an 11g database running under Unix. It would be real nice if I could use dbms_output so I could also run it from sqlplus and get output.
