this question has answer here: find full path of python interpreter? 5 answers is there way programmatically find python version used install current package? if have package called mypackage , has in setup.py like: scripts = ["myscript.py"] suppose install package easy_install or pip using particular python version, python 2.x: /usr/local/bin/python2.x setup.py install then in myscript.py , how can find out /usr/local/bin/python2.x used install mypackage myscript.py opposed other python version available on system? i'd know full path , not version info because want use /usr/local/bin/python2.x in script. use sys.executable . a string giving absolute path of executable binary python interpreter, on systems makes sense. if python unable retrieve real path executable, sys.executable empty string or none.

we have 2 entities entity1 , entity2, entity1 contains set of entity2, have thousands of entities stored in database of entity type entity2 referenced instance of entity1, myentity. now if add more entity2 entities collection , try persist myentity, newly added entities of entity2 persisted. my question how behavior on persist of myentity , whether existing members of relation travel memory , new members added or new members added database without bringing existing members memory if have thousands of referenced entities, might better not map relationship , instead query when needed - allowing use paging or other mechanisms reduce amount of entities read in @ time. depends on type of mapping is, owning relationship needs mapped (the 1 doesn't have mapped by) set foreign key in database. set entity2 side owning side if isn't already. if m:m relation table , doesn't make sense map entity2 side instead - add entity relation table read in same way. new e

what valid characters can use in php names variables, constants, functions, methods, classes, ...? the manual has some mentions of regular expression [a-za-z_\x7f-\xff][a-za-z0-9_\x7f-\xff]* . when restriction apply , when not? the [a-za-z_\x7f-\xff][a-za-z0-9_\x7f-\xff]* regex applies when name used directly in special syntactical element. examples: $varname // <-- varname needs satisfy regex $foo->propertyname // <-- propertyname needs satisfy regex class classname {} // <-- classname needs satisfy regex // , can't reserved keyword note regex applied byte-per-byte, without consideration encoding. that's why allows many weird unicode names . but regex restricts only these "direct" uses of names. through various dynamic features php provides it's possible use virtually arbitrary names. in general should make no assumptions characters names in php can contain. parts arbitrary strings. doing th

i have long list of xy coordinates, , convert numpy array. >>> import numpy np >>> xy = np.random.rand(1000000, 2).tolist() the obvious way be: >>> = np.array(xy) # slow... however, above code unreasonably slow. interestingly, transpose long list first, convert numpy array, , transpose faster (20x on laptop). >>> def longlist2array(longlist): ... wide = [[row[c] row in longlist] c in range(len(longlist[0]))] ... return np.array(wide).t >>> = longlist2array(xy) # 20x faster! is bug of numpy? edit: this list of points (with xy coordinates) generated on-the-fly, instead of preallocating array , enlarging when necessary, or maintaining 2 1d lists x , y, think current representation natural. why looping through 2nd index faster 1st index, given iterating through python list in both directions? edit 2: based on @tiago's answer , this question , found following code twice fast original version: >>> i

i have coordinates (x,y,z) of center of spheres stored in numpy array. want able rotate spheres respect z-axis getting weird results. code rotation seems moving , right. maybe intended result rotation, don't think is. here code: theta = math.pi/6 ct = math.cos(theta) st = math.sin(theta) z = np.array([[ct, -st, 0], [st, ct, 0], [0, 0, 1]]) self.atoms = np.array([[90,100, 1], [140,100, 1]]) self.atoms = self.atoms.dot(z) here image looked before rotation: and here looks after: you have translate entire system center of rotation center of system. the equations used rotation use work if rotating around origin. for translation can multiply matrix having direction of translation last row. anyway, entire transformation p' = inv(t) * r * t * p (where p each point of figure , p' in final result, see example) inverse of translation matrix negate sign of translation components. edit (worked out example -- might have transpose -- switch rows columns

i know maybe general question know how make reusable select (or input) when wating options (by ajax request) shows 'charging ...' message selected option. so example in of views can use directive called 'ajax-charged' , every select directive have behaviour. the html imagine while charging: <select ng-options="opt in options" ajax-charged> <option>charging ... </option> </select> the charged html: <select ng-options="opt in options" ajax-charged> <option>opt1</option> <option>opt2</option> <option>etc</option> </select> i thought in changing options array 'charging ...' item, how reusable? other approach welcomed! your directive need know array it's watching. can pass directive, , have the directive watch array. i created fiddle showing in action: http://jsfiddle.net/tmvfn/1/ html: </select> <select ng-model="

the nsurlrequest class ( ios docs , os x docs ) in cocoa has timeoutinterval property. docs state if during connection attempt request remains idle longer timeout interval, request considered have timed out. what 'idle' mean, here? best can tell, means in practice if set 30 second timeoutinterval , call method sends nsurlrequest , if body of http response hasn't returned 30 seconds after sending request, request times out. what's going on? a few things can think of might trigger idleness timer reset: receiving http headers, or receiving part of body. (if either) matters in reality? no bytes received 30 seconds normal definition. should able write simple http server (there sample projects over) , run on private port, connect prove yourself. to simulate timing out in server, add "40" or constant byte promising client, client wait forever 40 bytes bytes @ end aren't ever coming.

i have html page in have 2 select s. <select id="field" name="field" onchange="checkvalidoption();"> <option /> <option value="plugin id">plugin id</option> <option value="name">name</option> </select> <select id="operator" name="operator" onchange="checkvalidoption();"> <option /> <option value="equals">equals</option> <option value="contains">contains</option> <option value="not contains">not contains</option> <option value="regex">regex</option> </select> what i'd happen checkvalidoption() make if "plugin id" selected in field option equals (and it's selected) , otherwise other options available. idea on how approach this? i tried changing innerhtml of operator select in js: document.getelement

i have query. it's taking 1100 ms don't think should. select * pageinfo url = @url or url @url2 the url /sub/id , /sub2/id/thing . have index on pageinfo(url) . body of page ~10k , sample got me 1120ms 2 rows (<20k). feels wrong takes long. should able both pages on network in less time. what can speed things up? have index, i'm not sure else can do. using like prevent use of index. compare sqlite> explain query plan select * pageinfo url = @url or url @url2; 0|0|0|scan table pageinfo (~500000 rows) sqlite> to sqlite> explain query plan select * pageinfo url = @url or url between @url2 , @url3; 0|0|0|search table pageinfo using index pi (url=?) (~10 rows) 0|0|0|search table pageinfo using index pi (url>? , url<?) (~31250 rows) sqlite> you should use between , construct arguments query @url2 , @url3 such /sub2/1234/thing?page=0 and /sub2/1234/thing?page=99999999

is there actual difference between this public class outerclass { private class innerclass { public innerclass() {} } } and this? public class outerclass { private class innerclass { private innerclass() {} } } accessing private members class more complicated because jvm doesn't allow this. result compiler injects accessor methods makes slower or stack trace more complicated. for these reason leave package local. btw constructor of abstract class doesn't need public either. may protected or package local private static class { private a() { throw new error(); } } public static void main(string... ignored) { new a(); } prints stack trace element. exception in thread "main" java.lang.error @ main$a.<init>(main.java:8) @ main$a.<init>(main.java:6) @ main.main(main.java:12) make constructor package local , second 1 disappears.

i doing task work , unfortunately tables designed horribly , can't far modifying structure (one of our major programs here has been based off these outdated tables years). being said, need find way use sql server (tsql) count number of distinct columns in given row. example: i have table columns name , fielda , fieldb , fieldc , fieldd , etc want return table each of rows, returning name , number of distinct columns fielda - fieldd visually: jim - 1 - 3 - 4 - 6 john - 1 - 1 - 1 - 2 jane 2 - 2 - 3 - 3 would return jim - 4 john - 2 jane - 2 one way unpivoting data , subsequently grouping again. gives ability use count(distinct) : select name, count(distinct val) t unpivot (val col in (fielda, fieldb, fieldc, fieldd)) unpvt group name; however, efficient way keep processing on single row -- no join s or group by s or union s. assuming none of values null , following works 4 columns: select name, 4 - ((case when fielda in (fieldb, fiel

i've seen ton of different questions , answers problems people having retrieving height , width of views, particularly this thread. the following mentioned methods retrieve view dimensions: onwindowfocuschanged() in activity subclassing type of view you're using , overridding either onsizechanged(), onlayout(), or onmeasure() using viewtreeobserver , addongloballayoutlistener() each of them seem work in cases, while in other cases people doesn't work correctly. since there isn't setondimensionsknown(ondimensionsknown odk) or similar method view class, of these methods (or possibly 1 not mentioned) give me dimensions view have, regardless if it's drawn yet, has wrap_content or fill_parent parameters, or has explicit height , width set in px, dp, or similar? edit: perhaps specific example helpful, i'm trying make popupwindow wrap it's contents, , offset in -x direction value of it's width. problem contents width, , popupwindows width, not

ok guys, time creative. have list of integers, , want preserve integers in 5 green boxes below. thought finding 5 minimums, , going left , right each 1 until next integer distance far. may difficult last boxes have scattered values maintain. so cliff notes, have list of integers want make 5 lists of integers from, each 1 of 5 lists holding values of 1 of green boxes. i sorry if question seems dumb, wanting see if other people had better ways of going 1 mentioned above. edit: perhaps levenberg-marquardt algorithm help? if understand math books xd. swear math explanations never written in english, if shows me use, , how to, , understand it. can go read out of book again , confused on again! that possible solution: let call list of integer p[n]. define new list of point, call max[n], calculated way: if ((max[n] < p[n]) || (n == 0)) max[n] = p[n]; else max[n] = max[n-1]; in way, max[n] list green line above graph: first solution: identify points i

i need delete around 300,000 duplicates in database. want check card_id column duplicates, check duplicate timestamps. delete 1 copy , keep one. example: | card_id | time | | 1234 | 5:30 | | 1234 | 5:45 | | 1234 | 5:30 | | 1234 | 5:45 | so remaining data be: | card_id | time | | 1234 | 5:30 | | 1234 | 5:45 | i have tried several different delete statements, , merging new table no luck. update: got working! alright after many failures got work db2. delete from( select card_id, time, row_number() on (partition card_id, time) rn card_table) rn > 1 rn increments when there duplicates card_id , time. duplicated, or second rn, deleted. i suggest take approach: create temporary table tokeep select distinct card_id, time t; truncate table t; insert t(card_id, time) select * tokeep; that is, store data want. truncate table, , regenerate it. truncating table, keep triggers , permissions , other
