i'm building first worpess plugin. 'hammu dating' not showing in 'settings' panel in wp-admin. plugin activated in 'plugin' panel. followed instructions here . add_action( 'admin_menu', 'hammenu' ); function hammenu() { add_options_page( 'hammu dating opties', 'hammu dating opties', 'manage-options', 'hd_menu_1', 'hammu_options' ); } function hammu_options() { if ( !current_user_can( 'manage_options' ) ) { wp_die( __( 'no rights' ) ); } echo '<div class="wrap">'; echo '<p>nothing interesting here, yet</p>'; echo '</div>'; } note: part of plugin code the add_options_page(); function carries wrong capability slug: manage-options use manage_options instead. hope helps!

i tried searching google , stackoverflow, didn't found such way!! is there something, means in google+ api using can number of circles (public information) particular profile, have g+ id ? i went through that, found was, 1 can public information profile, when user has authenticated app. although in graph-api fb, afair can such public information (about posts, pages) without asking permission. i've updated question, if guys still think doesn't conform stackoverflow community, leave me comment , i'll delete it, instead of giving negative votes. (friendly request) [edit] the idea not number of circles particular user, number of circles in user. for e.g. https://plus.google.com/u/0/117907144223534027934 - in 353 circles https://plus.google.com/u/0/118337805761123404690 - in 15 circles the number of circles person has not public information. google+ not expose user's circle structure in way. however, if has been shared publicly, can retrieve ...

i wasn't sure term is, have word_set in form of defaultdict [(word, value), ...] came function parsed raw data. i have other functions: reduceval(word_set, min_val) , reduceword(word_set, *args) , etc removes pairs that: have value less min_val, have (word) in [args], respectively. pretty follow same structure, e.g. def reduceval(word_set, value): "returns word_set (k, v) pairs v > value)" rtn_set = defaultdict() (k, v) in word_set.items(): if v > value: rtn_set.update({k:v}) return rtn_set i wondering if there more concise, or pythonic, way of expressing this, without building new rtn_set or maybe defining entire function if learn use dict comprehensions don't need have separate functions of these different filters. instance, reduceval , reduceword replaced with: # python 2.7+ {w: v w, v in word_set.items() if v > value} {w: v w, v in word_set.items() if w in args} # python 2.6 , earlier dict((w...

i have been trying develop rather simple server in nodejs. basically, going simple api requires authentication (simple username/password style). not need kind of frontend functionality (templating etc.). problem is, can't seem head around approach of express/node. specifically, questions are: how wire in authentication? pass several handlers every route requires authentication, or there more elegant way this? how express middleware (like app.use(express.bodyparser()) ) work? alter contents of request or response object? specifically, if use body parser (internally formidable?), access request data supposed parse? when using authentication , have, say, credentials stored in database more information individual client associated, @ point extract information? i.e., when user logs in, fetch user record on login , pass on, or fetch in every handler requires information? ultimately, know of open source application take at? i'd see has simple authentication , maybe utili...

in searching html within current directory, if name contains substring assume file exists , continue operation instead of saying file doesn't exist. have file "protocolhttp.html" - in testing make sure "protocol.html" throws error, doesn't. continues operation of program. i make sure filename matches exactly. here's have: for file in glob.glob('*.html'): if protocolfile in file: open(file) f: contents = f.read() else: print "could not locate '" + protocolfile + ".html'" sys.exit(1) any ideas or further steps check validate this? i think code same thing as: if os.path.isfile(filename): open(filename) f: contents = f.read() else: print 'could not locate {0}'.format(filename) sys.exit(1)

i have large table 100,000,000 rows. i'd select every n'th row table. first instinct use this: select id,name table id%125000=0 to retrieve spread of 800 rows (id clustered index) this technique works fine on smaller data sets larger table query takes 2.5 minutes. assume because modulus operation applied every row. there more optimal method of row skipping ? if id in index, thinking of along these lines: with ids ( select 1 id union select id + 125000 ids id <= 100000000 ) select ids.id, (select name table t t.id = ids.id) name ids option (maxrecursion 1000); i think formulation use index on table. edit: as think approach, can use actual random ids in table, rather evenly spaced ones: with ids ( select 1 cnt, abs(convert(bigint,convert(binary(8), newid()))) % 100000000 id union select cnt + 1, abs(convert(bigint,convert(binary(8), newid()))) % 100000000 ids cnt ...

i'm beginning use prepared statements sql queries in php , in starting have come question. i have function grabs user's id table @ login. want user able use either username or email address login. so sql statement is: select * `login` `username`=? or `emailaddress`=? now when in query username , emailaddress same because can either or. so when binding statements bind variable twice: bind_param('ss', $user, $user); so value username , emailaddress needs same. want $user value of both placeholders. my questions are: am doing correctly? is there more efficient way? yes, have bind twice. if opposed reason, rephrase query as: select * `login` l cross join (select ? thename) const l.`username` = thename or `emailaddress` = thename; this using subquery name parameter can referred multiple times in query.
