i working pyhton on codecademy , stucked in 1 part. goal this: "define function called reverse takes string 'text' , returns string in reverse. may not use reversed or [::-1] this." did 1 , not working this: t = raw_input("enter: ") def reverse(t): x = [] in range(len(t)): x.append(t[len(t) - - 1]) print ''.join(x) but when working. t = raw_input("enter: ") x = [] in range(len(t)): x.append(t[len(t) - - 1]) print ''.join(x) what wrong first one? the first not work because, you're not calling reverse function on t . def reverse(t): x = [] in range(len(t)): x.append(t[len(t)-a-1]) return ''.join(x) t = raw_input("enter: ") print(reverse(t)) in example you're obtaining input, doing nothing it.

i've set expandablelistview clickable childs change color when they're clicked on. i'd make instead of instantly changing color, changes animation. i noticed default animation clicking elv (or type of list, suppose) pretty cool (at least in version of os): expands kind of grey color covering entire item instant before going original color. idea using animation change color of clicked child, obvious difference: wouldn't go it's original color. complicated?, if not how can done? if has information animating child color change please let me know well.

suppose have class called myclass, i'm writing function should return object of type myclass. object exists before calling function. do: myclass function() { return myclassinstance; } but remembered pointers , references , think doing create new copy of myclassinstance , return it, waste of memory. thought, why not this: myclass * function() { return &myclassinstance; } so result accessed as, myclass * object; object = function(); object->"class member"... is correct? you surely can that. run ok. has no problems aspect of syntax. need take care there more 1 pointers pointing object. may bring hidden problems.

i working on project want show pie chart image added. have searched google , other posts in stackoverflow, not find solution. solution appreciated. note: suggestions of third-party library welcome. please not suggest mpandroidchart think query can implemented using simpler method. you can use library https://github.com/philjay/mpandroidchart achieve this. add below in xml: <com.github.mikephil.charting.charts.piechart android:id="@+id/chart" android:layout_width="match_parent" android:layout_height="match_parent" /> in java code: piechart chart = (piechart) findviewbyid(r.id.chart); example code: https://github.com/philjay/mpandroidchart/blob/master/mpchartexample/src/com/xxmassdeveloper/mpchartexample/piechartactivity.java there lot of variances available. another library consider is: https://github.com/lecho/hellocharts-android

there convolve function in swissdelphicenter.ch , set kernel , resulting image blurred, there no parameter apply more blur unless call function multiple times (not desired coz of performance issue). how apply more blur image radius parameter in photoshop gaussian filter? i using kernel apply gaussian filter: 1    2    1 2    4    2 1    2    1 you can make larger gaussian kernel - 5x5, 7x7 etc. performance decrease proportional size^2. kernel size faster use approach fft-based convolution. edit fft-based convolution: have data array a, array kernel values k (same length, zero-padded). conv(a, k) = backfft (fft(a) * fft(k)) to make convolution, 1 can find fourier transform of data find fourier transform of kernel multiply them element-by-element (note numbers complex) make inverse fourier transform of product real part of look @ fast convolution algorithms section in wiki , part 13.1 of numerical recipes (almost practical manual) if interesting in f

i using search api , elasticsearch connector in drupal 7 site. have hosted elasticsearch in aws. searching works without issues. add facetapi filters in drupal.org search result page. it seems facetapi removed elasticsearch , added support aggregation. https://www.elastic.co/guide/en/elasticsearch/reference/2.1/breaking_20_removed_features.html#_facets_have_been_removed https://www.elastic.co/guide/en/elasticsearch/reference/1.3/search-aggregations.html but aggregation not supported. https://www.drupal.org/node/2643822 https://www.drupal.org/node/2503343 any suggestion or idea how can achieve this? there other way or missing here? yeah. use https://www.drupal.org/project/elasticsearch_connector and use elasticsearch version 1.x. elasticsearch 2.x in dev.

i want stream set of documents query in couchbase using single query. problem return a couple of million of documents , want them gradually couchbase, light processing , write result file stream, saving me loading whole result set memory. know if possible in couchbase? edit: sorry, forgot i'm trying in c# currently, way directly use paging on query retrieve results in chunks. comes obvious downside of result set (potentially) changing between page retrievals, if have other process continues change data in background. in c# (typing memory, apologies if doesn't compile straightaway): var pagesize = 100; var pageindex = 0 iqueryresult<dynamic> result = null; { var query = string.format("select mybucket.* mybucket limit {0} offset {1}", pagesize, pageindex); result = await bucket.queryasync<dynamic>(query); pageindex += result.rows != null ? result.rows.count : 0; } while(result.success && result.rows.count > 0); you

how can hide content without disturbing rest of content in jquery? need toggle also? .css{visibility:hidden} doesn't me toggle. you can toggle element p or particular class or id. <script> $(document).ready(function(){ $("button").click(function(){ $("your_element_neme").toggle(); }); }); </script>

i've used stackoverflow years, today first time i've felt need ask question. know if following code made more efficient, because i'm writing multiple copies of script, entering different sql tables. what does: querys vmware, outputs $data truncates sql table inserts $data dbo.t_vm_guest_details inserts dbo.t_vm_guest_details dbo.t_vm_guest_details_history ideas efficiency: just above foreach ($line in $data), possible include "foreach column in $data" dynamically build 'standard' sql insert query, based on count of columns, names & values. or there easier way insert $data sql table elsewhere , i'm making difficult myself? keeping sql table column names same powershell output should help? the following block fills $data list of vms (powercli): $data = @() $allvms = get-vm | select * $entry = @() foreach ($vm in $allvms) {
