so have dataframe (df) dated data on monthly time series (end of month). looks this: date data 2010-01-31 625000 2010-02-28 750000 ... 2014-10-31 450000 2014-11-30 475000 i check on seasonal monthly effects. this simple do, how can go extracting month date create categorical dummy variables use in regression? i want this: date 01 02 03 04 05 06 07 08 09 10 11 2010-01-31 1 0 0 0 0 0 0 0 0 0 0 2010-02-28 0 1 0 0 0 0 0 0 0 0 0 ... 2014-10-31 0 1 0 0 0 0 0 0 0 1 0 2014-11-30 0 1 0 0 0 0 0 0 0 0 1 i tried using pd.dataframe(df.index.month, index=df.index)... gives me month each date. believe need use pandas.core.reshape.get_dummies variables in 0/1 matrix format. can show me how? thanks. this how got april: import pandas pd import numpy np dates = pd.date_range('20130101', periods=4, freq='ms') df = pd.dataframe(np.random.randn(4), index=dates, columns=['data']) df.

i have template named profile contains 3 other templates. 1 of these templates {{> postlist}} and helper function template is template.postlist.helpers({ posts: function() { return posts.find({rph: {$in : postsarr}}); } }); the problem on going route, postlist template empty, since postsarr calculated later after dom has loaded on basis of other 2 templates. but, if click on other route , come route, template renders properly. what should template renders itself? the easiest way session , though it's worst option: template.postlist.helpers({ posts: function() { return posts.find({rph: {$in : session.get('postsarr') }}); } }); if call session.set('postarr', ...) anywhere in code posts helper update automatically. second option use shared reactive variable: var postsarr = new reactivevar(); and inside helper: return posts.find({rph: {$in : posts.arr.get() }}); now can postsarr.set(...) , should work fine. remember meteor

i using jquery unobtrusive ajax , mvc ajax.beginform() validate form via c# server side. i'm replacing form itself. it's working fine, wondering: let's form triggering "save database" action , action succeeded. there no errors in form don't want post form client, rather json message triggers success dialog on front end. problem form replace happening. how can force not replace form when json server? i guess i'm asking is: how can not have div updated other code instead? i know onsuccess, fired after div replace, want skip replace. you should jquery ajax post form instead of ajax.beginform kind of functionality. point of ajax.beginform post form , update given target. if want return either partial view or json object, should page replacing , success dialog triggering jquery.

i bound use module provided maven artifact not follow conventions, in sense contains two jar files: artifactid-version.jar , artifactid-version-suffix.jar . have reference both in project, , not know how this. when add dependency artifact in pom (in usual way), end first jar in classpath. how second one, *-suffix.jar, on classpath, too? (without manually copying project structure.) unfortunately, communication provider of artifact - well, difficult. otherwise straight go , ask them first. in case matters: artifact contains vaadin widgetset, , suffix "widgets". first jar contains java classes , xml files, second 1 (with suffix) static web content: css, images, html files. apparently accompanies vaadin theme (provided maven artifact). browsed vaadin docs on whether common way of delivering widgetset, no avail. the suffix mention known classifier in maven terminology . to both dependencies, add dependency pom (leave 1 have, too): <dependency>

i have user type in how want message sent defined $time variable this loop code have right now $time = $_post["time"]; ($x = 0; $x < $amount; $x++) { mail($completenum, $subject, $message, $headers); sleep($time); } the issue code messages never sent through, believe it's because sleep function halts script. ideas? php isn't correct language this, want try javascript or similar. php designed let dynamically build page when loaded. putting sleep in there, you're delaying load time of page, , server and/or browser going time out - pages aren't expected take excessively long times load, , indicates error. different browsers going different things, , you'd need modify timeout settings on if delay long one. a scripting language keeps running in browser going able kick off periodically want, , update page - want code keeps executing after page loaded. alternately, if want php only, php code store request in database, , have

i'm creating web-site , use html build page layout. have 1 big html document index.html . there header, middle section , footer. many scripts used form checks, animations, slider , etc. slider has several background images , different content each slide. index.html has lot of stuff in , when user loads first time quite bit of traffic used. when user fills login form, client side jquery script checks form , data posted php script server side checks performed , session started. after successful response server want index.html reload different header. came 2 solutions this: * i can load different document using ajax header container. i can redirect html document(for example index2.html has exact same code exception header container part changed. i don't both of solutions. using ajax can avoid forcing user reload traffic. seems not elegant me reloading header make white square appear in section break user's design experience , looks clunky. while it's asyn

i flatten/unflatten classes using automapper, not sure if possible. have listdefo , valuedefo, how list , values defined. user can add them data object. not worried storing valuedefo id against datavalue, need string value. here classes public class listdefo { public long id { get; set; } public virtual icollection<valuedefo> values { get; set; } } public class valuedefo { public long id { get; set; } public string value { get; set; } } public class data { public long id { get; set; } public icollection<datavalue> values { get; set; } } public class datavalue { public long id { get; set; } public virtual listdefo listdefo { get; set; } public string value { get; set; } } currently if use automapper, have following models, data object values property, , each datavalue have id, listdefoid , value. public class datamodel { public long id { get; set; } public icollection<datavaluemodel> values { get; set; } } p

i know use isnan test if value equal nan. reliable? the nan property represents value “not number”. special value results operation not performed either because 1 of operands non-numeric (e.g., "abc" / 4), or because result of operation non-numeric(e.g., attempt divide zero). while seems straightforward enough, there couple of surprising characteristics of nan can result in hair-pulling bugs if 1 not aware of them. for 1 thing, although nan means “not number”, type is, believe or not, number: console.log(typeof nan === "number"); // logs "true" additionally, nan compared – itself! – false: console.log(nan === nan); // logs "false" a semi-reliable way test whether number equal nan built-in function isnan(), using isnan() imperfect solution. a better solution either use value !== value, produce true if value equal nan. also, es6 offers new number.isnan() function, different , more reliable old global isnan() function.

say there 5 open tabs in single browser, , using node.js , socket.io. client , server exchange packets maintain (establish) communications. will connection client lost if of 1 tab closed? how can determine if user closed browser? yes, socket.io establishes new connection every tab. you're going want using session cookies figure out user current socket.io connection communicating with.
