WILL JUSTICE PREVAIL?

i trying create , application requires me take captured image , place on current camera preview 0.5 alpha. "overlay" image serves guide capturing next picture; client use overlay compare current frame in preview captured image. simple way approach retrieve last file captured , set view. however, captured image not match camera previews resolution , aspect ratio, causing overlay , preview mismatch in representation of objects (the same object can vary in size between preview , captured image). have tried: using camera preview callbacks store current frame data, inefficient , doesnt work (also has slight translation, dimensions accurate) using aforementioned previous-file method , trying scale down or scale accordingly, match aspect ratio (maybe math wrong [i used aspect ratio of preview calculate area in original image] , still possible use approach? if way in on appreciated). researching ways capture contents of surface view, no avail. currently, 2 possible method

now tried use intent extra's pass , receive through bundle string array list reason list never passes, when try use get(0) retrieve first string list null pointer error, can please me on this? first activity (signup activity): public static final string string_array = "geoquiz.android.bignerdranch.com.string_array"; final arraylist<string> mystringarray = new arraylist<>(); mystringarray.add(username.gettext().tostring()); mystringarray.add(firstname.gettext().tostring()); mystringarray.add(lastname.gettext().tostring()); intent = new intent(signupactivity.this,loginactivity.class); i.putextra("string_array", mystringarray); startactivity(i); second activity (login activity): final bundle stringarraylist = getintent().getextras(); final arraylist<string> stringarray = new arraylist<> (); stringarray = stringarraylist.getstringarraylist("string_array"); if(username.gettext().tostring().equals(stringarray.get(0))

i have model field position = positiveintegerfield(unique=true) . given instance of model, want instance next highest position (subject filters). if instance 1 highest position, want wrap around 0 , return instance lowest position; if instance one, want return itself. here's code: count = player.objects.count() return player.objects.filter(game_id=self.game_id, is_alive=true).annotate( relative_position=(f('position') - self.position - 1 + count) % count ).order_by('relative_position')[:1].get() (the reason + count because negative number modulo positive 1 negative in sql.) this requires 2 database queries. suspect it's possible in 1 query, using annotate , count , haven't figured out how put such query together. can done, , if so, how? not 1 query, beats 2 queries , annotations: players = player.objects.filter(game_id=self.game_id, is_alive=true).order_by('position') try: return players.filter(position__lt=self.posit

i'm porting on web page work on ipad (since company uses). on desktop used :hover navigate menus. on ipad need able click on menu item expand menu (which works fine). have added onclick event supposed display button allows collapsing menu. button supposed appear menu expanded, click event isn't registered until second click of menu item, button doesn't appear. here top navigation menu's hover. on first touch on list item (:hover) works. #nav li:hover { background-color:#80ccff; color:black; opacity:1; } #nav li:hover > ul.child { top:39px; display:inline; position:absolute; text-align:left; } here top of navigation html: <ul id="nav"> <input id="button1" style="margin-bottom:10px;" class="button1class" name="button1" type="button" value="collapse menu" onclick="hidebutton();return false;"/> <li class="green"><a id="close" href=

i want display transparent box (with button on that) surround table row user mouse over. searched on google, pages tell how highlight row when mouse over. i use javascript add mouse on event. $('tr').on('mouseover', displaybox); can me solve problem or give me reference article? for example: the overlay we can create overlay :before pseudo element — tbody tr td:first-child:before : it given 100% width , stretch width of row. it given same height td , stretch height of row the table made position: relative cells :before child positioned relative table , can stretch across entire row. the buttons div the buttons can provided in div of last cell in each row — no javascript needed. need tweaked offset low in firefox. the div inside each rows last cell hidden opacity until row hovered. when hovered shown with: tr:hover td > div { opacity: 1; } the td:last-child made position: relative overlay div has position: absolute

given following scenario: computer connects public server behind firewall. computer b connects same public server behind firewall. now, there way computer talk directly computer b using outbound connections without sending data through server? can server link connections somehow? two peers, talking each other, using outbound connections instead of dealing inbound firewall issues. possible, yes. easy, no. at least 1 of firewalls needs updated forward port on external ip port on machine behind it. other machine can connect port open bidirectional tcp/ip connection. to accomplish this, can make use of upnp on firewall accomplish "hole punching" or " nat traversal ". once firewall port open, forward port number on public server , pass along public ip address known server along other machine. can create connection.

i working on major update android utility flash in recovery , uses bash scripting... problem is, kinda know nothing bash! right now, have 2 files... common file contains variables , script file holds file lists. here problem part of common script: if [ ${android_version} == 5.* ]; rm -rf /system/$file_name; else if [ -e ${file_name}.* ]; rm -rf /system/$file_name; else rm -f /system/$file_name.apk; fi; fi; and here's example of $file_name 's come from: # aosp aosp_remove_list="bootanimation browser ..."; bootanimation_list="media/bootanimation.zip"; browser_list="app/browser app/chromebookmarkssyncadapter"; so in common file, looks see if lollipop. if not, (this issue) supposed @ file name individual app lists , see if contains file extension. if doesn't remove $file_name + .apk . so in above example, browser's files .apk added , removed system bootanimat

so learning python hard way. in 1 of exercises print string literals variables between them. noticed unlike other languages python automatically adds space between string literal , variables. curious how that. below example of mean. example.py: total_so_questions_asked = 1 print "i have asked", total_so_questions_asked, "question far." terminal: $ python example.py have asked 1 question far. this silly , not important curious, , hoping can enlighten me! it's cool feature of python. there 2 things having multiple arguments does: adds space around parameters necassary, , converts each of arguments string seperately. let's @ how simple can make potentially complicated code using these features: a = 5 b = 3 c = + b print a, "plus", b, "equals", a+b if couldn't have list of individually casted parameters, it'd ugly: print str(a) + " plus " + str(b) + " equals " + str(a+b) from zen

i trying build interactive scatter-plot using shiny. using iris data, have user select x , y dimensions of scatter plot *petal vs sepal) , output simple scatter plot of selected dimensions. pretty straightforward. first needed build function allows me pass strings representing dimensions ggplot. did , tested static data. works fine. next define 2 dropdowns , 2 subsequent strings (using shiny) petal , sepal dimensions (these x , y axis). i next set 2 string variables using shiny's reactive() function using switch statement. this appears things go wrong. the error is: error: cannot coerce type 'closure' vector of type 'character' i've taken number of steps debug code. first plugged in hard coded dimensions (e.g. "petal.length") final line of code output$myplot = renderplot({myplotfunct( ... this works great. plot renders expect to. i added debug line track value of string passing plot function. bingo. it's empty. why empt

my question related social network analysis. starting research work on citations network analysis of 3 universities. question how can collect data citation network? or there intelligent software can identify references link of citations automatically? or can through simple programming? thanks in advance. you try this: http://www.vosviewer.com/home but guess if want write own custom-made software, work better, because you'd able fine-tune needs. which package recommend depends on languages know. think of existing modules sort of stuff written in python, if you're familiar it, go ahead , google citation extractors. alternatively, program yourself, shouldn't hard. consider using graph database, neo4j it.

i'm relatively new running production node.js apps , i've been having problems server timing out. basically after amount of usage & time node.js app stops responding requests. don't see routes being fired on console anymore - it's whole thing comes halt , http calls client (iphone running afnetworking) don't reach server anymore. if restart node.js app server starts working again, until things inevitable stop again. app never crashes, stops responding requests. i'm not getting errors, , i've made sure handle , log db connection errors i'm not sure start. thought might have memory leaks installed node-memwatch , set listener memory leaks doesn't called before server stops responding requests. any clue might happening , how can solve problem? here's stack: node.js on aws ec2 micro instance (using express 4.0 + pm2) database on aws rds volume running mysql (using node-mysql) sessions stored w/ redis on same ec2 instance node.js

a software architecture question: i have top two/thirds of django app: view , template layers. i'd use external resource model. how? i'd use of django model layer possible, orm. external resource specialized java package, providing content via flexible backend xml api. my current strategy sort of thin model shim api: django models without fields, instead series of @property s, each function pulling data external resource, needed. is idea? how else solve problem? judging deafening silence, gather answer is: differently. we're rebuilding project consume json restful interface instead.
