i'm following ryan bates' tutorial on adding time zones rails app. http://railscasts.com/episodes/106-time-zones-revised (it's tutorial, way) anyway, ryan says it's idea validate submitted time zone ones rails knows about. put rule users' model: validates_inclusion_of :time_zone, in: activesupport::timezone.zones_map(&:name) that works fine in development. however, when run app on heroku, not timezone "melbourne" (and many others - i'm testing au time zones). on heroku, rule in user model, not accept time zone of "melbourne". why be? time_zone_select view helper returns "melbourne" - rails must aware of it.

i understood basic rationale reverse key index reduce index contention. if have 3 numbers in index: 12345, 27999, 30632, can see if reverse these numbers, next number in sequence won't hit same leaf block. but if numbers :12345,12346,12347, next numbers 12348,12349 (incremented 1) hit same leaf block if index reversed: 54321,64321,74321,84321,94321. so how reverse index helping me? supposed particularly while using sequences if we're talking sequence-generated value, can't @ 5 values , draw many conclusions. need think data has been inserted , data inserted in future. assuming sequence started @ 12345, first 5 values inserted sequentially. sixth value 12350. reverse , 05321 go far left of index. you'd generate 12351. reverse 15321 , that's again toward left-hand side of index between first value generated (54321) , recent value (05321). sequence generates new values, they'll go further right until resets every 10 numbers , you're ins

using mongodb console can write native mongodb query using distinct key sort this: db.mycollection.distinct('mykey').sort('mykey', 1) using java driver expect able write same query this: mycollection.distinct("mykey").sort(new basicdbobject("mykey", 1)); however, doesn't work because dbcollection#distinct() returns type list , not type dbcursor dbcollection#find() . how can write distinct query sort using java driver? mongodb doesn't support server-side sorting distinct command. what's happening in console distinct('mykey') call returns array , you're calling javascript sort method on array returns sorted version of array. parameters pass sort ignored. to equivalent in java do: list mykeys = mycollection.distinct("mykey"); java.util.collections.sort(mykeys); to unique keys using server-side sort use aggregate . here's how you'd in shell: db.mycollection.aggregate([

so trying change format of text file has line numbers every couple of lines make cleaner , easier read. made simple program goes in , replaces of first 3 characters of line spaces, these 3 character spaces numbers can be. actual text doesn't start until few more spaces in. when , have end result printed out comes out diamond question mark in , i'm assuming result of missing characters. seems of missing characters apostrophe symbol. if let me know how fix appreciate :) public class conversion { public static void main(string args[]) throws ioexception { bufferedreader scan = null; try { scan = new bufferedreader(new filereader(new file("c:\\users\\nasir\\desktop\\beowulftesting.txt"))); } catch (filenotfoundexception e) { system.out.println("failed read file"); } string finalversion = ""; string currline; while( (currline = scan.readline()) !=null){ if(currline.length()>3) cur

i have following sentence: graft concepts has partnered with\u00a0several sites\u00a0to offer customization options backplates, customers able design own with\u00a0 i'd rid of instances of "\u00a0", whether or not connected other words, e.g. "with\u00a0several" how using regex python? i've tried experimenting re.compile() , re.findall(), couldn't working? thanks. you can use .replace : s = s.replace('\\u00a0', ' ')

i'm creating music album review site, user posts album reviews (pins), , select 1-5 stars display on show page. i'm using letsrate gem , works fine input stars on form when submitting new pin , editing. need display input on show page. when have <%= @pin.rates %> on show page, displays this: [#<rate id: 8, rater_id: 1, rateable_id: 36, rateable_type: "pin", stars: 4.0, dimension: nil, created_at: "2013-08-19 22:28:36", updated_at: "2013-08-19 22:28:36">] i need stars: 4.0 display 4 stars. (and not allow them edited in show view) this rate model: class rate < activerecord::base belongs_to :rater, :class_name => "user" belongs_to :rateable, :polymorphic => true belongs_to :pin attr_accessible :rate, :dimension end i saw question posted, doesn't explain how use helper: displaying individual user ratings (letsrate gem) if use <%= rating_for @pin => , stars show up, can rerate them, not

i've been googling , down, searching on free pascal wiki , on (obscure) mailing lists , have come empty on how use ioctl() or fpioctl() on free pascal. i have bug report free pascal's bugtrack code enumerates network interfaces. the code not compile since libc unit has been deprecated. lot of similar questions libc point wiki entry talks it's demise. not give indication on sioc*if* stuff has gone. does mean of ioctl functionality has gone? using find , grep , under /usr/share/fpcsrc/<fpc-version>/, i've been able track usage of fpioctl() in relation terminals termios unit. other stuff uses looks it's under other oss. apart i'm unable find of use if want like: if ioctl(sock, siocgifconf, @ifc)= 0 begin {...} end; so, can free pascal community give me pointer what's current situation if 1 wants ioctl calls under linux? does baseunix.fpioctl meet use case? have @ baseunix documentation . found an example of using

i using jquery 2.0.2 , have error in ie8: object doesn't support property or method 'addeventlistener' jquery.min.js, line 4 character 6105 somehow codes fine chrome , firefox, except ie8. getting these errors resulted to: the value of property '$' null or undefined, not function object i included query on top of other js files have using: <script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js"></script> i know jquery2+ doesnt support ie8, dont want use lesser version of jquery. jquery 2.x has dropped support ie < 9, if want support ie7 & 8 use latest version of 1.x branch - 1.11.0 from jquery jquery 2.x has same api jquery 1.x, not support internet explorer 6, 7, or 8. notes in jquery 1.9 upgrade guide apply here well. since ie 6/7/8 still relatively common, recommend using 1.x version unless no ie 6/7/8 users visiting site.

i trying understand relationship in pandas between dateoffset , periods , tslib.period_ordinal . when create new period using: pd.period("2013-12", freq="q-dec") , see "q-dec" resolved base of 2000, base in addition components of datetime parsed date string passed tslib.period_ordinal returns 175. where if anywhere dateoffset come in? meaning of base? there docs on period_ordinal? i looking add new frequencies, such 52–53-week fiscal year (see: https://github.com/pydata/pandas/issues/4511 ) , wondering start.

i wish generate error bar each data point in ggplot2 using generic function extracts column names same using names function. following demo code: plotfn <- function(data, xind, yind, yerr) { yerrbar <- aes_string(ymin=names(data)[yind]-names(data)[yerr], ymin=names(data) [yind]+names(data)[yerr]) p <- ggplot(data, aes_string(x=names(data)[xind], y=names(data)[yind]) + geom_point() + geom_errorbar(yerrbar) p } errdf <- data.frame('x'=rnorm(100, 2, 3), 'y'=rnorm(100, 5, 6), 'ey'=rnorm(100)) plotfn(errdf, 1, 2, 3) running gives following error: error in names(data)[yind] - names(data)[yerr] : non-numeric argument binary operator any suggestions? thanks. you need pass character string containing - ( 'a-b' not 'a' - 'b' ) eg, ggplot(mtcars,aes_string(y = 'mpg-disp',x = 'am')) + geom_point() in example plotfn <- function(data, xind, yind, yerr) { # subset names le
