i on shared hosting , have cpanel, apache, php run fastcgi. php store error log? is there other way can find error log on shared hosting environment instead of having go through entire site structure error_log files? i have access php.ini (i using php version 5.2.16). php stores error logs in /var/log/apache2 if php apache2 module. shared hosts storing log files in root directory /log subfolder. but...if have access php.ini file can this: error_log = /var/log/php-scripts.log according rinogo 's comment: if you're using cpanel, master log file you're looking stored (by default) at /usr/local/apache/logs/error_log if else fails can check location of log file using <?php phpinfo(); ?>

i ran situation git cherry-pick x have conflicts, created inserts (when verified git diff ). i re-ran git show x > my.patch , , did patch -p1 < my.patch on tree. got better results, conflicts, cleaner result. what git special cherry-picks? use git 1.7.0.4. edited: cleaner results, mean resulting tree matched lot more results of git show x , whereas git cherry-pick included lot more code. when cherry-pick commit, commits result using metadata of commit, not diff represents - you'll original commit message , author. patch pipeline working tree contents want, you'll have commit yourself, git commit -c <original-commit> copy metadata cherry-pick have. cherry-pick has additional options helpful, , can accept multiple commits (perhaps specified rev-list range). patch doesn't support of that. i'm not sure assertion result "cleaner". suggesting git applied diff differently patch did?

i'm translating stuff matlab python language. there's command, unique(a), in numpy . since matlab program runs 'rows' command also, gives little different. is there similar command in python or should make algorithm same thing? assuming 2d array stored in usual c order (that is, each row counted array or list within main array; in other words, row-major order), or transpose array beforehand otherwise, like... >>> import numpy np >>> = np.array([[1, 2, 3], [2, 3, 4], [1, 2, 3], [3, 4, 5]]) >>> array([[1, 2, 3], [2, 3, 4], [1, 2, 3], [3, 4, 5]]) >>> np.array([np.array(x) x in set(tuple(x) x in a)]) # or "list(x) x in set[...]" array([[3, 4, 5], [2, 3, 4], [1, 2, 3]]) of course, doesn't work if need unique rows in original order. by way, emulate unique(a, 'columns') , you'd transpose original array, step shown above, , transpose back.

i have code this c.execute('create table if not exists base (id integer not null, col2 text not null, col3 integer, primary key(id, col2))') this code gives me sqlite3.integrityerror exception though sure writing record first time. so, tried c.execute('create table if not exists base (id integer, col2 text, col3 integer, primary key(id, col2))') this inserts row fine in base table but, id column not auto incremented @ all. what can do? idea? in sqlite, autoincrement behavior when 1 integer column primary key. composite keys prevent autoincrement taking effect. you can similar result defining id primary key, adding additional unique constraint on id, col3 . if that's still not quite want (say, id's don't need unique @ all), have use trigger make autoincrement work.
