i have large number of ascii files named in order of form data.xxxx.tab, "xxxx" number between 0000 , 9999. each file contains 5 columns, first x-coordinate, second y-coordinate , remaining 3 variables wish plot against x-coordinate. need know how write loop in gnuplot 4.6, plot consecutive graphs of 1 of variables against x-coordinate. i tried instructions given in following posts: plotting gnuplot several files and gnuplot : plotting data multiple input files in single graph but these created single graph containing curves data files together, whereas need consecutive graphs plotted 1 after another, showing evolution in time of variable graph. the following should work: # fix axes proper comparison between graphs set xrange [0:10] set yrange [0:10] # if want animated gif set term gif animate set output 'output.gif' # plot data [n=0:9999]{ plot sprintf("data.%04d.tab", n) using 1:2 title 'case '.n } the %04d string

i absolute new ruby on rails , running following command $rails generate devise user i expected file _devise_create_users.rb generated . generating file _add_devise_to_users.rb. when run command rake db:migrate after this, gives me error , sqlite3::sqlexception: no such table: users: alter table "users" add "email" varchar default '' not null. since there no user table created. any headways suggested ? i believe need capitalize user rails generate devise user make sure rollback mistakes made db in prior attempts.

the image file identical. once comes drawable , 1 file system . here code. <imageview android:scaletype="fitend" android:id="@+id/partner_logo" android:layout_width="51dp" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:contentdescription="@string/parter_logo" /> i set partner logo dynamically, load id webserver , then set imageview.setimagebitmap(bitmap bitmap); with imageresource looks , expect in bitmap case small. here picture compare the logo (black arrow points) set via setbitmap . seem not up-scaled -- the logo (read arrow points) set via setimageresource . looks like. so question why there difference here? works scaletype in case of bitmap? because setimageresource() automatically scale image. if want use setim

i new rtree/btree data structures. creation of tree bottom-to-up process searching node/range search/knn search top-to-bottom process. using knn search wanting improvement: data trajectory of points, spatially close each other. in order search knns every point on entire trajectory, want search 1 point first, other points, don't want start root again, instead want start results of first point, , go upper parents. enable me avoid searching lot of unnecessary pages. problem here how can go upper child parent in rtree/btree structure? should change tree creation process , whenever split happens, fill parent[] property of child? there other simpler ways problem? you could: store pointer parent node in children node know how move upwards in nodes structure. between queries store pointer last leaf node , there using pointer parent move upwards, check parent node, again move upwards etc. until node different subtree should picked. store pointers children nodes in every

i using jasmine write unit tests angularjs factory returns call restangular. take example, function functobetested(params) { return restangular.all('/foo').getlist(params); } it straightforward test whether or not all() being called on restangular. how can test whether getlist() gets called on returned restangular object after all() has returned? at moment, have beforeeach(function() { module('ui.router'); module('myservice'); module('restangular'); }); describe('functobetested', function() { beforeeach(function() { httpbackend.expectget('/foo').respond([]); }); it('should call on restangular', function() { spyon(restangular, 'all').and.callthrough(); functobetested({}); httpbackend.flush(); expect(restangular.all).tohavebeencalled(); }); }); if try follow same pattern , along lines of expect(restangular.all.getlist).tohavebeencalled(); things stop working. not able f

i'd model following, generic abstract class gets type constructor (ala arraylist()) public abstract class abstractparent<t> { protected abstractparent(t... params){ //(...) } } public child<u,v> extends abstractparent<????>{ public child(u param, v param2){ super(param, param2); } } but canot use '?' or parent's t '????' type. want child<string,string> abstractparent<string> while child<string,integer> abstractparent<? extends object> , ...similarly how arrays.aslist() method works: aslist("a","b") returns list<string> whereas aslist("a",1) returns list<? extends object> . why disallowed or how can workaround it? if want parent type of supertype of both u , v, you'll still have explicitly specify in child 's generic parameters. closest thing can class child<x, u extends x, v extends x>

is there rabbit mq plugin or application can subscribe rabbit mq messages, save them disk, , publish messages @ same rate came in? i starting rabbitmq , trying figure out best way set integration tests. do want fanout messages 2 separate queues ? if so, create 2 queues , bind them fanout exchange. messages published exchange replicated. can configure 1 of 2 queues save messages disk !

basically, cannot figure out how prevent form generator encapsulating in hash (filter{...}), making easy form set params used in view's scoping. has_scope code in controller: has_scope :degree_id has_scope :discipline_id has_scope :competency_id has_scope :type_id has_scope :year simple_form code in view: <%= simple_form_for :filter, url: analyze_school_path, method: :get |f| %> <%= f.error_notification %> <div class="form-inputs"> <%= f.input :y, label: 'year', collection: @years, include_blank: '- year -' %> <%= f.input :discpline_id, label: 'discipline', collection: discipline.all, include_blank: '- discipline -' %> <%= f.input :competency_id, label: 'competency', collection: competency.all, include_blank: '- competency -' %> <%= f.input :type_id, label: 'type', collection: jobtype.all, include_blank: '- type -' %> </div>

when include recipe in recipe how override attributes. it looks include recipe used default attributes not attributes of recipe when run in run_list. when creating wrapper cookbook, common override attributes. suppose, have my_web_server cookbook my_web_server/recipes/default.rb this: include_recipe "apache2" and override attribute default_site_enabled apache2 cookbook. file my_web_server/attributes/default.rb should like: override['apache']['default_site_enabled'] = true and don't forget specify dependencies in my_web_server/metadata.rb like: depends "apache2"

it's first time using tuple's might doing wrong or missed small. used have repetitive code : if (!b1fturn) { if (b1turn) { fixcall(b1status, ref b1call, ref b1raise, 1); fixcall(b1status, ref b1call, ref b1raise, 2); rules(2, 3, "bot 1", ref b1type, ref b1power, b1fturn, b1status); autoclosemsb.show("bot 1 turn", "turns", thinktime); ai(2, 3, ref bot1chips, ref b1turn, ref b1fturn, b1status, b1power, b1type); turncount++; b1turn = false; b2turn = true; } } if (b1fturn && !b1folded) { bools.removeat(1); bools.insert(1, null); maxleft--; b1folded = true; } if (b1fturn || !b1turn)
