  • C++ for Ruby scripters

    - by Aaron Cohen
    I am a fairly capable Ruby scripter/programmer, but have been feeling pressure to branch out into C++. I haven't been able to find any sites along the lines of "C++ for Ruby Programmers". This site exists for Python (which is quite similar, I know). Does anyone know of a guide that can help me translate my Ruby 'thoughts' into C++?

  • Is there a more modern regexp handler for Open Object Rexx

    - by Brent.Longborough
    The regular expression class (rxregexp.dll) that comes with ooRexx (I'm on 4.0.0) is relatively low on function compared, say, with Python's re module (even at 2.5.2). It appears to have no assertions, no facilities for group extraction, or for substitution. Greedy or lazy matching is a global pattern option, rather than flagged by an additional "?". Basically, a pre-PCRE regular expression engine. Does anyone know if anything with more up-to-date function is available?

  • Introduction to midi programming

    - by bobobobo
    So I have a little (musical) keyboard that has USB midi interface. I know you can program to this (many programs accept input from the midi device via USB interface) but where do you begin to program a midi device?

  • How to launch from Eclipse in Low priority under Windows?

    - by adum
    I'm running programs from Eclipse (on Windows) that eat a lot of CPU time. To avoid bogging down my whole machine, I set the priority to Low with the Task Manager. However, this is a cumbersome manual process. Is there a way Eclipse can set this priority automatically? EDIT: I realized that each particular launcher (Java, Python etc) has its own configuration method, so I will restrict this question to the Java domain, which is what I need most.

  • Exhaustive (or even just large) list of languages/stacks used for popular sites?

    - by jacko
    As a result of a conversation with a colleague today, I've been searching (unsuccessfully) for a large'ish list of what technology stacks are being used popular websites and standalone applications today. We're aware of the big ones like Facebook (php/ ), Twitter (scala/cassandra), Youtube (python/?), Digg (php/cassandra), stackoverflow (.net mvc/sqlserver), but we're looking for a more complete list. It would also be interesting to hear about any stats for desktop apps also? Can anyone help?

  • Common Lisp's equivalent of \r inside the format function?

    - by liszt
    Basically, I'd like to do the following, only using Common Lisp instead of Python: print("Hello world.\r\n") I can do this, but it only outputs the #\newline character and skips #\return: (format t "Hello world.~%") I believe I could accomplish this using an outside argument, like this: (format t "Hello world.~C~%" #\return) But is seems awkward to me. Surely I can somehow embed #\return into the very format string, like I can #\newline? Yeah ehh, I'm nitpicking. Thanks for any help!

  • Plural blocktrans problem with Django

    - by jorde
    I'm trying to translate a small block of text using Django's build in i18n. I don't know why but the following won't show up in different language: {% if store.rating_count %} {% blocktrans with store.rating_count as count %} {{ count }} review {% plural %} {{ count }} reviews {% endblocktrans %} {% else %} {% trans "No reviews" %} {% endif %} And a snipplet from my django.po (created with makemessages): #: templates/reviews/category.html:65 #, python-format msgid "%(count)s review" msgid_plural "%(count)s reviews" msgstr[0] "%(count)s arvostelu" msgstr[1] "%(count)s arvostelua" Other strings translate fine from the same template. I have rerun compilemessages few times.

  • Subversion: svn status displays tons of undesired .metadata files

    - by FarmBoy
    I'm trying to set up Subversion on Ubuntu Linux. It seems to be working, except that when I made one change and tried svn status, I found about 100 files had been changed, in the .metadata directory. My ~/.subversion/config file currently contains the following line: global-ignores = *.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *.pyo *.rej *~ .*.swp .DS_Store What do I need to add to ignore the .metadata files? The directory under consideration is used by Eclipse for Python development using PyDev, if that matters.
