(i'm new mvc model, , don't know if i'm following best practices.) thanks. the error due object cant declared that, there different ways it: var obj1 = { : function() { console.log('obj1'); } }; var obj2 = function() { var b = function() { console.log('obj2'); }; return { a: b } }; var obj

what i'd validate property values entered on msiexec /qn calls. as example, our runtime sql server database authentication, need offer windows authentication , sql user authentication. represent these radiobuttongroup on ui dialog window. default value, "rt_db_logon_type" property, going through ui "sqlauth". for silent installs, i'd to: 1) set default value of "rt_db_logon_type" property "sqlauth", if user enters no value "rt_db_logon_type" property on silent install command line. 2) check launch condition fail if value of "rt_db_logon_type" property set other "sqlauth or "winauth" (case insensitive). my code (located in equivalent of product.wxs file): <setproperty id="rt_db_logon_type" value="sqlauth" before="launchconditions" sequence="both">not rt_db_logon_type</setproperty> <condition message="!(loc.rt_db_logon_type_messg

i developing embedded platform using sdk based on freertos. need create task xtaskcreate , don't understand usstackdepth parameter. freertos documentation says: the size of task stack specified number of variables stack can hold - not number of bytes. example, if stack 16 bits wide , usstackdepth defined 100, 200 bytes allocated stack storage. stack depth multiplied stack width must not exceed maximum value can contained in variable of type size_t. so, how stack width? platform-dependent? targeting 32-bit risc processor xtensa lx106 the freertos task stack width port dependent. in portmacro.h , should find definition portstack_type . if dig further tasks.c (remember have access freertos source code), you'll find stack allocated size of ( ( size_t ) usstackdepth ) * sizeof( stacktype_t) . , in portmacro.h you'll find stacktype_t typedef'd same portstack_type .

in processing i've wrote simple program gets pixel of image , sends it's values serial port. done inside draw function , iterates through pixel array in each draw event. so image of 200 x 200 there 40000 pixels , draw function called 40000 times. don't see result of change make during processing. after 30 seconds data serialized , changes becomes visible. what need in order draw , see result during writing serial? asynchronous thread solution? i've tried this, , calling redraw method, nothing seems help. for 200x200 image loop through 40000 pixels, shouldn't need call draw() function often. can have loop each each pixel running once per draw() call, in case pixels changing, otherwise, can cache pixel values once in setup() regarding writing serial, shouldn't complicated. here's proof of concept sketch illustrating 1 way of writing thread writes serial in parallel: import processing.serial.*; int w = 200; int h = 200; int np = w*h;//tota

if user input inserted without modification sql query, application becomes vulnerable sql injection , in following example: $unsafe_variable = $_post['user_input']; mysql_query("insert `table` (`column`) values ('$unsafe_variable')"); that's because user can input value'); drop table table;-- , , query becomes: insert `table` (`column`) values('value'); drop table table;--') what can done prevent happening? use prepared statements , parameterized queries. these sql statements sent , parsed database server separately parameters. way impossible attacker inject malicious sql. you have 2 options achieve this: using pdo (for supported database driver): $stmt = $pdo->prepare('select * employees name = :name'); $stmt->execute(array('name' => $name)); foreach ($stmt $row) { // $row } using mysqli (for mysql): $stmt = $dbconnection->prepare('select * employees name = ?');

i've started playing robocode , i've encountered angle problem @ first robot project. i've wright following code in order shot enemies nearby ; public void onscannedrobot(scannedrobotevent e) { double radarangle ; double gunzeroangle ; double difference ; radarangle = getradarheading (); gunzeroangle = getgunheading () ; difference = radarangle - gunzeroangle ; system.out.print("target :" + radarangle + "\nzero : "+ gunzeroangle +" \nfark : "+ diff + " \n "+ " *********************** "+ "\n" ); if (fark != 0) { turngunright (fark) ; fire(1); my problem when enemies far away there dead angles gun can't swipe this; and here angles i've written robolog ; guess angle differences less 1 degree problem. sample robots "corners" can focus on target @ angle. can me ??? you should heading of scanned robot scannedrobotevent then t

i make sentiment analysis in r. in have dataset column "svolume" values 1,5,41,... column different names of company. last column dates yyyy-mm-dd. i plot times series dates each company, if have 3 company, have 3 lines, on x axis dates, , y axis svolumes. i wrote : data2=data[order(as.date(data$date, format="%d/%m/%y")),] in order order data dates. plot.ts(data2$svolume) axis(1,1:40,data2$date) and plot time serie of svolumes , put dates on x axis. have 2 problems: have 1 line can't see difference between 3 company (i love have line of total if possible), , second problem it's impossible read dates there horizontal , wrote 1 on each others. there way write dates verticaly example in order read it? i have plot this: times series plot 1 instead of "websites" have "volumes" , instead of "shoes,socks,lace" have name of companies/subjects or svolumes time series plot 2 that's how data looks like: > he

after rotated coordinates system translating along new axes. somehow possible translate along axes before rotation? idea user uploads image , can rotate it, zoom , move around middle of viewport. somehow failt o achive of functions ta once. any suggestions? edit i.e. there canvas. draw image there. rotate 90° , want translate on x axis. moves down screen. because axes turned around. edit here code snippet use transformation. image rotated in it's (0,0) point. why translate in way rotatet in middle point. afterwards draw image in offset point. p.push(); p.translate(canvaswidth/2, canvasheight/2); p.rotate(angle * p.two_pi/360); var x = -loadedimage.width/2 - offsetx; var y = -loadedimage.height/2 - offsety; p.image(loadedimage, x, y); p.pop(); edit i decied translate first, , rotate. makes translating correct rotates around wrong pivot point. can't have guess. var c = document.getelementbyid("

i wish read data .dat file without saving file first. in order so, code looks follows: urlsearch= 'http://minorplanetcenter.net/db_search/show_object?utf8=&object_id=2005+pm'; url= 'http://minorplanetcenter.net/tmp/2005_pm.dat'; urlmidstep=urlread(urlsearch); urldata=urlread(url); received= textscan(urldata , '%5s %7s %1s %1s %1s %17s %12s %12s %9s %6s %6s %3s ' ,'delimiter', '', 'whitespace', ''); data_received = received{:} urlmidstep 's function "search", in order able create temporary .dat file. data stored in urldata , long char array. when use textscan in matlab, 12 columns desired, stored in cell array data_received . however, in octave various warning messages: warning: strread: field width '%5s' (fmt spec # 1) extends beyond actual word limit (for various field widths). question is, why result different in octave , how fix this? shouldn't octave behave same matlab, in theory dif
