i list files of directory , sort file extension: dim files list(of io.fileinfo) = get_files(directory, true, validextensions).orderby(function(x) x.extension).tolist how can add in same instruction parameter sort name content this?: x.name.tolower.contains("word") i've tried separate comma (yes, stupid): dim files list(of io.fileinfo) = get_files(directory, true, validextensions).orderby(function(x) x.extension, x.name.tolower.contains("word")).tolist update i've tried use @p.s.w.g solution not return desired result. but if make 2 lists separate desired sort in second list: dim files list(of io.fileinfo) = _ get_files(directory, true, validextensions).orderby(function(x) x.extension).tolist dim files2 list(of io.fileinfo) = _ files.orderby(function(x) x.name.tolower.contains("word")).tolist but want improve doing in first list. use thenby method: dim files list(of io.fileinfo) = _ get_files(directory, tru

i have app works on dev, when try on heroku, load 1 user. doesn't matter logs in, "guestuser" signed in, , therefore whoever logs in gets see 'guestusers' data. first go @ real node app. here code: /** * module dependencies */ var express = require('express'), routes = require('./routes'), api = require('./routes/api'), http = require('http'), path = require('path'), mongoose = require('mongoose'), passport = require('passport'), localstrategy = require('passport-local').strategy; var app = module.exports = express(); var uristring = process.env.mongolab_uri || process.env.mongohq_url || 'mongodb://localhost/hellomongoose'; mongoose.connect(uristring, function (err, res) { if (err) { console.log ('error connecting to: ' + uristring + '.

i had written original code 1.1 using abrhams twitteroauth , oauth.php in late 2012 , code using /1/ endpoint. worked fine in connect, authorized, long term token, updates , tweet... no problems. when 1.0 sunsetted functionality broke (duh!) , took long time end on desk. first thing did change api /1/ /1.1/ , we're working... mostly... there problems: problem 1: i'm authorizing, getting token etc. can login test account (@test1) , manually tweet, tweet picked via statuses/update , processed according our needs. if tweet directed specific user (@test2) statuses/update on test2 never detects incoming tweet although seen on twitter @ tab "interaction". $twitter = new twitteroauth(consumer_key, consumer_secret, $access_token['oauth_token'], $access_token['oauth_token_secret']); $params = array('screen_name' => $tw_name, 'include_entities' => "true",

i have script reads in data csv file data.table , splits text in 1 column several new columns. using lapply , strsplit functions this. here's example: library("data.table") df = data.table(prefix = c("a_b","a_c","a_d","b_a","b_c","b_d"), value = 1:6) dt = as.data.table(df) # split prefix new columns dt$px = as.character(lapply(strsplit(as.character(dt$prefix), split="_"), "[", 1)) dt$py = as.character(lapply(strsplit(as.character(dt$prefix), split="_"), "[", 2)) dt # prefix value px py # 1: a_b 1 b # 2: a_c 2 c # 3: a_d 3 d # 4: b_a 4 b # 5: b_c 5 b c # 6: b_d 6 b d in example above column prefix split 2 new columns px , py on "_" character. even though works fine, wondering if there better (more efficient) way using data.table . real datasets have >=10m+ rows, time/m

i need delete items in wpf listbox, use code : while (listbox.selecteditems.count > 0) { listbox.items.remove(listbox.selecteditem); } but problem listbox contains several same items, example : chocolate milk orange milk banana apple milk if select 2nd occurence of milk @ 4th position , try delete given code, remove first occurence of milk @ 2nd position (not selected) , selected 2nd occurence of milk @ 4th position. i have tried : while (listbox.selecteditems.count > 0) { listbox.items.removeat(listbox.items.indexof(listbox.selecteditem)); } but result same. could give me clue on ? try this if (listbox.selecteditem != null) { listbox.items.removeat(listbox.selectedindex); }

i'm newbie ember data , i've done date fixture data today i'm trying graduate real deal , realising don't know enough how connect model , api's call signature. specifically i'd able call endpoint get /activities/[:user_id]/[date] . load array of "activity" objects given date. know can offset api's directory with: ds.restadapter.reopen({ namespace: 'api' }); in case api prefix appropriate. think should able date component solved setting route this: this.resource('activities', { path: '/activities' }, function() { this.route('by_date', {path: '/:target_date'}); }); the above educated guess because i'm @ loss on how user_id component url signature. can help? there tutorials or examples of basic ember data use cases? also, because know i'm going run next ... how 1 add parameters url string (aka, /foobar?something=value) versus parameters url (like above)? -=-=-=-=-=-=-=-=-=-=-

i have table this: i need numbers, wich repeated in different citys , these citys quantity each number. that table, need result: number | repeated citys quantity ---------- 222 | 2 because number 222 repeated in 2 different city. i have solution: 1) greate function returns unique values array, example array_unique() 2) , then: select number, array_length(uniq_city_list, 1) ( select number, array_unique(array_agg(city)) uniq_city_list mytable group number ) t array_length(uniq_city_list, 1) > 1 but, may there better solution doing this? think not optimal query... select number, count(*) ( select number, city t group number, city ) s group number having count(*) > 1 order number

in lecture on java, computer science professor states java interfaces of class prototypes public methods, plus descriptions of behaviors. (source https://www.youtube.com/watch?v=-c4i3gfye3w @8:47) and @ 8:13 in video says go discussion section teaching assistants learn means prototype. what "prototype" mean in java in above context? i think use of word prototype in context unfortunate, languages javascript use called prototypical inheritance totally different being discussed in lecture. think word 'contract' more appropriate. java interface language feature allows author of class declare concrete implementations of class provide implementations of methods declared in interfaces implement. it used allow java classes form several is-a relationships without resorting multiple inheritance (not allowed in java). have car class inherits vehicle class implements product interface, therefor car both vehicle , product.

i've written small graphics engine game has multiple canvases in tree(these represent layers.) whenever in layer changes, engine marks affected layers "soiled" , in render code lowest affected layer copied parent via drawimage(), copied parent , on root layer(the onscreen canvas.) can result in multiple drawimage() calls per frame prevents rerendering below affected layer. however, in frames nothing changes no rendering or drawimage() calls take place, , in frames foreground objects move, rendering , drawimage() calls minimal. i'd compare using multiple onscreen canvases layers, described in article: http://www.ibm.com/developerworks/library/wa-canvashtml5layering/ in onscreen canvas approach, handle rendering on per-layer basis , let browser handle displaying layers on screen properly. research i've done , i've read, seems accepted more efficient handling manually drawimage(). question is, can browser determine needs re-rendered more efficiently can

i have weird problem app shows black screen when try re-launch it. happens , can't find solution after digging code weeks! this how happens: open app, stuff , return home screen. after several hours, relaunch app , opens blank screen (no anr or whatsoever thrown!). i've put log messages oncreate() , onresume() method, never show up. logcat shows me lot of "failed binder transaction" errors when happens. other various other threads, not passing images or large objects through intent. "transactiontoolargeexception" not being thrown either. so how data/anr/traces.txt looks (unfortunately, app not being "traced"): http://www.xup.in/dl,19638443/traces.txt . and dumpsys.txt: http://www.xup.in/dl,10520097/dumpsys.txt . my testdevice happens: samsung galaxy s1 (android 2.3.6) the blank screen doesn't seem occur on ics phone (lg optimus g) any ideas? do use admob sdk in application? solved issue downgrading version 6.4.1 6.2

i developing experimental vm, , right have separate instruction datatype operations each , every type, safe. e.g. have add instruction 8, 16, 32 , 64 bit signed , unsigned integers, float, double , long double. that's 11 instructions 1 operation. true operations support types, so, end lot of instructions , little head room. so wondering if instructions can operate regardless of underneath type, can cut number , make room more instructions i'll in desperate need of in future, since don't want exceed byte instruction. instead of having add , sub , etc.. every data type why not have them operate on "registers" , have mov instruction datatypes 0 out/sign extend rest (if any) of register. this of course assuming have things in vm. might want add more information question.

i using sphinx/restructuredtext create html , pdf docs project , including output of argparse command line tools. @ moment pasting output in manually plan @ point switch autogenerated output. the problem while formatting fine named parameters (like -x or --xray) doesn't work on positional parameters. looks absence of leading '-' on parameter name confusing it. output looks normal text without neat indentation etc. so question is, there exist markup force formatting positional parameters if had leading '-' characters? if not, suggest in docs or code should start looking put myself? you may use sphinx-argparse extension. not use output of argparse help, instead introspects argparse parser , provides proper sphinx markup both positional arguments , options, formatting them definition list proper labels. sub-commands handled. http://sphinx-argparse.readthedocs.org/en/latest/ it cover needs in: plan @ point switch autogenerated output

the following confusing me lot. have been spending quite bit of time trying understand why collection.find() doesn't work regex passed object. regex match coming on http wrapped in body of post request. try gather query (in string format) , perform query. problem seems unless regex written inside node without quotes, won't work. is, must literal without quotes. for example, following works fine: var query1 = { company: { '$regex': /goog/ } }; collection.find(query1, {}).toarray(function (err, docs) { // got results back. awesome. }); however, if data comes wrapped in object, doesn't return anything. suspect it's because value gets quoted behind scenes (i.e. "/goog/"): // assume var query2 = { company: { '$regex': query.company } }; collection.find(query2, {}).toarray(function (err, docs) { // got nothing back. }); i have tested mongo shell , can confirm following: // returns 5 results db.getco

(i'm using masm32) .data msg db 31h, 00h, 32h, 00h, 33h ;convert string "123" .code start: invoke messagebox, 0, addr msg, 0, 0 call exitprocess end start as can see each character or byte separated null byte, can show 1 byte, "1" instead of "123" if can concatenate each readable byte until reaches end of string. mov ebx, offset msg mov ecx, ebx add ebx, 2 invoke lstrcat, ebx, ecx maybe add loop also, don't know better way code or if have better solution can share. in order work on string, need know length of string. done using null terminate string. functions not take string length argument, 00h, , print string it, messagebox doing, printing "1" , seeing next character 00h, stops printing. in case, there no null terminator @ end of string, can string length @ assembly time symbol "$&qu
