jsPerf tests for split join replace

Today I have found this code in connect middleware: exports.normalizeSlashes = function normalizeSlashes(path) { return path.split(sep).join('/'); }; So I have immediately jumped to jsPerf and wanted to compare this to alternative methods (for speed). Unlucky as always, I have run into several nonsense tests:

• http://jsperf.com/split-join-vs-replace-47 - Both revisions 1,2 are wrong not comparing the same things
• http://jsperf.com/regexp-vs-split-join2 - another treasure

and we could you with the list. Again and again, broken tests and misleading measurements. Please all of you who run into this article, and write or use jsPerf results please read using-jsperf-correctly.

BTW: there is enough room for fiddling elsewhere. On of the tips: "http://jsfiddle.net"

Of course split/join is much slower then intuitive replace. At least with browsers and JSPerf

Update 2013-01-06:

Irony: I have authored BUGGY TEST AS WELL: http://jsperf.com/normalizeslashes-split-join-vs-replace and I hope fixed version 2 is better ;-) http://jsperf.com/normalizeslashes-split-join-vs-replace/2

rvm and ruby for some beEF on OSX

There are many articles, some of them did not work for me and may not work for you… This is what I have made to succeed:

# uninstall all previous trials of rvm (modify .bash_profile and remove)
rm -rf .rvm*
# latest stable in my time was 2.0.0-p247
curl -L https://get.rvm.io | bash -s stable --ruby
# obviously this install does not modify profile
source ~/.rvm/scripts/rvm
# just looking
rvm list known
ruby --version
# switch from apples version ruby 1.8.7 to "latest"
rvm use ruby-2.0.0-p247
#
rvm gemset create beef
rvm use ruby-2.0.0-p247@beef
# swich to cloned source 
cd ~/beef/
# make ruby in this folder to be 2.0.0
echo 'rvm use ruby-2.0.0-p247@beef' > .rvmrc
# install
bundle install

# run
source ~/.rvm/scripts/rvm
rvmsudo ./beef

git whatever --recursive (submodules)

Git submodules are pain in the ... some commands support --recursive but not all. In this case, this snipped can help:

git-recursive(){
 git "$@"
 git submodule foreach --recursive \
  git "$@" 
}

any improvements are welcomed ;-)

How much is Twitter Button (on OTN)

Just another funny fact: for such a small button down on the page, grey and almost invisible

you pay 27K on transfer ?

Sorry, just playing with Charles (before uninstalling this annoying freeware) from my Mac. Oh, refer(r)er is http://www.oracle.com/technetwork/index.html

Quickly finding all spring config files

spring-configs(){
 git grep --name-only "http://www.springframework.org/" -- '*.xml' 
}

Now let's compare several "boilerplate, demo, sample projects" (just from what I have on my hd):
