python - IPython Notebook locale error -


this question has answer here:

after installing latest mac osx 64-bit anaconda python distribution, keep getting valueerror when trying start ipython notebook.

starting ipython works fine:

3-millerc-~:ipython python 2.7.3 |anaconda 1.4.0 (x86_64)| (default, feb 25 2013, 18:45:56)  type "copyright", "credits" or "license" more information.  ipython 0.13.1 -- enhanced interactive python. ?         -> introduction , overview of ipython's features. %quickref -> quick reference.      -> python's own system. object?   -> details 'object', use 'object??' details.

but starting ipython notebook:

4-millerc-~:ipython notebook

results in valueerror (with traceback):

running locale command terminal:

5-millerc-~:locale  lang= lc_collate="c" lc_ctype="utf-8" lc_messages="c" lc_monetary="c" lc_numeric="c" lc_time="c" lc_all=

i summarize here solution found on: http://blog.lobraun.de/2009/04/11/mercurial-on-mac-os-x-valueerror-unknown-locale-utf-8/

i added these lines .bash_profile:

export lc_all=en_us.utf-8 export lang=en_us.utf-8

i reloaded profile:

source ~/.bash_profile

i ran ipython again:

ipython notebook

changing locales

the above work english language in locale. 1 may want different settings.

at risk of stating obvious, discover current settings system, use:

$ locale

and retrieve list of valid settings on system:

$ locale -a

then choose preferred locale. example, swiss french locale, solution this:

export lc_all=fr_ch.utf-8 export lang=fr_ch.utf-8

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
