i'm using simple-jekyll-search create search page posts in jekyll. the json file search generated by: [ {% post in site.posts %} { "title" : "{{ post.title | escape }}", "category" : "{{ post.category }}", "tags" : "{{ post.tags | join: ', ' }}", "url" : "{{ site.baseurl }}{{ post.url }}", "date" : "{{ post.date | date: '%y %b %-d' }}", "content" : "{{ post.content | strip_html | strip_newlines }}" } {% unless forloop.last %},{% endunless %} {% endfor %} ] the problem characters incorrectly encoded in json file (though appear correctly in html). "you’ll" appears "you’ll" in json, example. there's issue incompatibility of character encoding, i'm not sure fix it. since it's incorrect in json, i'm guessing it's somewhere in template generate json, can't life of me figure out how

i have created dupe-check makes sure newly created usernames unique. it looks this: string p1 = <code>; //first 3 chars in first name string p2 = <code>; //first 3 chars in last name int p3 = 1; //unique identifier. boolean dupecheck; { dupecheck = false; (int = 0; < usernamelist.size(); i++) { if (usernamelist.get(i).equals(p1+p2+integer.tostring(p3))) { dupecheck = true; p3++; } } } while (dupecheck == true); this works, if return: return string.format("%s%s%d", p1, p2, p3); duplicate usernames names like: xxxyyy1 xxxyyy2 xxxyyy3 which great. want unique identifier ( p3 ) allways 3 digits long. string.format comes play, along problems. if return following code: return string.format("%s%s%03d", p1, p2, p3); for reason, dupe check fails , these usernames: xxxyyy001 xxxyyy001 xxxyyy001 can explain happening? if store usernames using %03d, i.e. leading zeros, should use when

consider isabelle code theory scratch imports main begin datatype expr = const nat | plus expr expr it quite reasonable instantiate plus type class nice syntax plus constructor: instantiation expr :: plus begin definition "plus_exp = plus" instance.. end but now, + , plus still separate constants. in particular, cannot (easily) use + in function definition, e.g. fun swap "swap (const n) = const n" | "swap (e1 + e2) = e2 + e1" will print malformed definition: non-constructor pattern not allowed in sequential mode. ⋀e1 e2. swap (e1 + e2) = e2 + e1 how can instantiate type class existing constant instead of defining new one? type class instantiations in isabelle introduce new constants parameters of type class. thus, cannot plus (written infix + ) shall same plus . however, can go other way around, namely instantiate type class first , later declare operations on type class constructors of datatype. one such case c

this first time using php in real project environment. project pretty simple, take existing, working php site , update html consistent html5. after designing html, inserting php previous site. works of time, few errors. instance: <? $sec = $_get['sec']; if ($sec == "1") { echo ('success!'); } ?> is causing error: notice: undefined index: sec in /file_that_holds_site_build. of course if url doesn't include append tag (=1) alerts message. so question this, missing causes $get when there no $sec ? how eliminate error on first page load? you're getting notice because you're trying access array index doesn't exist in scenarios. here's how should getting data out of request. $sec = array_key_exists('sec', $_get) ? $_get['sec'] : null;

this code, works, it's big. want refactor it. req_row = -1 req_col = -1 a.each_with_index |row, index| row.each_with_index |col, i| if col == 0 req_row = index req_col = break end end end if req_col > -1 , req_row > -1 a.each_with_index |row,index| row.each_with_index |col, i| print (req_row == index or == req_col) ? 0 : col print " " end puts "\r" end end input: 2d array 1 2 3 4 5 6 7 8 9 10 0 11 12 13 14 15 required output: 1 2 0 4 5 6 0 8 0 0 0 0 12 13 0 15 i'm surprised matrix class not used more: a = [[ 1, 2, 3, 4], [ 5, 6, 7, 8], [ 9, 10, 0, 11], [12, 13, 14, 15]] require 'matrix' m = matrix.rows(a) #=> matrix[[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 0, 11], [12, 13, 14, 15]] r, c = m.index(0) #=> [2, 2] matrix.build(m.row_count, m.column_count) {|i,j| (i==r || j==c) ? 0 : m[i,j]}.to_a #=&g

i have checkout system have created. there 3 different parts checkout flow. of these parts in same page. parts are: shipping info billing info order confirmation basically whenever done shipping info select proceed billing info , shipping info section hides , billing info section shows. same order confirmation. at top of page regardless of section showing, have call section labels: <ul class="checkoutmenu"> <div class="checkoutbutton" id="button1labl">1. shipping information</div> <div class="checkoutbutton" id="btnbillinginfolabl">2. billing information</div> <div class="checkoutbutton" id="button3labl">3. order confirmation</div> </ul> what wanting happen is, in active section customer in, section label different color. so if in shipping info section, section label different color. i show , hide different sections this: $(".shi

i downloaded netbsd-6.1.5-macppc.iso , burned "disk utitlity" of mac (have german version, don't know extactly how tool called in english versions) cd-rom. on system, planning install os typed following in openfirmware console: boot cd:0 netbsd.macppc i hear sound of cd-drive, this: boot cd:0 netbsd.macppc disc-label: load (noninterposed) notsupported-loadsize=0 adler32=1 load-size small! some powerpc macs quite fussy bootloader, , seem recall there changes cause issues older macs. as test might worth trying netbsd-5 or netbsd-4 iso see if boots you

what best way return documents in collection if want document.a == document.b? i've tried db.collection.aggregate([ { $match: { $eq: [ '$a', '$b' ] } }]) but returns no errors or results, because assume literally matching strings "$a" , "$b". there different way specify these fields? db.collection.aggregate([ { $project: { eq: { $cond: [ { $eq: [ '$a', '$b' ] }, 1, 0 ] } } }, { $match: { eq: 1 } }]) the above works, requires additional step of querying again whatever documents found or projecting possible fields. is there better way achieving query? basically, trying perform self join. operation not supported mongodb. concerning $eq operator, guessed: by design, $eq comparison query operator match field against value . but $eq comparison aggregation operator compare value of 2 expressions . i don't know other way perform need using $project step suggested. please note not sig

final edit (hopefully): oh god solved it! after upgrading pandas 0.15.2, solution seems work: trades['oedatum'] = (trades[['oedatum', 'oeuhrzeit']].apply (lambda x: dt.datetime.combine (x['oedatum'].date(), x['oeuhrzeit']), axis=1)) thank @edchum , @joris i'm trying pull data excelsheet via read_excel pandas dataframe: asset oedatum oeuhrzeit odatum ouhrzeit l/s entrykurs \ trade 1 eurusd 2014-06-12 12:00:00 2014-06-12 12:23:09 l 1.2456 2 usdjpy 2014-11-11 10:15:35 2014-11-11 10:34:50 s 126.6300 3 eurjpy 2014-12-23 13:15:24 2014-12-23 13:25:45 l 114.4600 4 gbpjpy 2014-12-23 14:27:36 2014-12-23 14:35:56 s 156.6000 the values i'm interested in, have following data types: oedatum datetime64[ns] oeuhrzeit object odatum
