i have implemented resque queuing system in rails app. want know flow of resque job starting enqueue removed out queue. the traditional work flow, along method used gem is, 1. resque enqueue job(resque::job.create) , 2. job calls 'perform' method of class(resque::job.perform), and 3. resque removes job queue. i debugged gem find out method used in step 3, couldn't find it. methods resque::job.destroy, resque::job.dequeue not responsible task, debugged. can tell me method using remove job queue . please note that, not want remove job explicitly, want typical resque method removes job queue. thanks in advance. resque uses 'dequeue' method remove job: def dequeue(klass, *args) job.destroy(queue_from_class(klass), klass, *args) end to pick job queue processing uses 'pop' method: def pop(queue) decode redis.lpop("queue:#{queue}") end

i'm working on migrating project jsp-centric using velocity. in many places jsp pages parsing strings display various things. makes jsp ugly , difficult maintain obviously. i have modified controller class work me (i.e. creating list of pojos), iterating on pieces using velocity. have feeling it's going come heavy resistance. i realize creating object comes overhead, makes our pages easier debug, write , use. besides fact separates ui core logic of occurring in background. not mention our appservers bored. database wincing in pain. see tenfold increase in users (which why developed parse strings in jsp & skip object creation) -- smells me of premature optimization. what further arguments support claim should eat cost associated object creation? object creation in java somewhat expensive, 15 years ago. java runtimes have improved lot since then. nowadays, java object creation faster in c++. it never expensive decisive factor in basic applicatio

i realize below code holds true integer.min_value == -integer.min_value == math.abs(integer.min_value) this because when negate -2147483648 , should become +2147483648 . since maximum positive integer can represented in java +2147483647 , integer overflow occur. when overflow occur, becomes -2147483648 again. i wondering, is there trap should keep eye on it, above situation? the biggest trap slient overflow of example. similar examples. long.min_value == -long.min_value; 0.0d == -0.0d 0.0f == -0.0f double.nan != double.nan float.nan != float.nan double.compare(double.nan, 0) == 1 double.nan > 0 false float.compare(float.nan, 0) == 1 float.nan > 0 false fyi byte.min_value != -byte.min_value; short.min_value != -short.min_value; character.min_value == -character.min_value;

i'm creating special ui control using html/css mimic windows 7 control panel buttons. far, i've got layout right , i'd add cosmetics it. as seen here, there gradient appears when hover on button mouse. http://m.cncfps.com/zack/files/this-control.png now, can see here i've got layout done. i'd add :hover effect whole div item background image. currently, here have css- yet doesn't work. no image shows in ie8, or firefox edit: works in chrome, not in firefox or ie. #cp .cp-item:hover { background:url(images/hoverbg.png) repeat-x; } it work background-color rather image. there's nothing (relevant) wrong css. the path image correct. it works in chrome. chrome seems more intelligent (or lenient) other browsers. if inspect page, it's inserting stuff: it doesn't work in other browsers because don't have proper page structure (no doctype, no <html> tag, no <body> tag, etc) - page doesn't val

live example: http://newsite.702wedding.com/vegas-wedding-chapels.asp works great in firefox, chrome, ie slide show arrow buttons move left. any permanent fixes? or how can address ie users , give left margin? (seems ugly, real fixs?) thanks much, james you can target internet explorer conditional stylesheets fix inconsistencies cause ie. it's not ugly - it's pretty common fix , if done requires small number of styles targeted @ ie. include ie specific css files so: <!--[if ie 7]> <link type="text/css" rel="stylesheet" href="ie7.css" /> <![endif]--> <!--[if lte ie 6]> <link type="text/css" rel="stylesheet" href="ie6.css" /> <![endif]--> the top selector targets ie7, while bottom targets browsers <= ie6. use <!--[if lte ie 7]> target browsers <= ie7 single stylesheet instead.

i running ubuntu guest os using vmware player on windows 7 machine. problem have syncing clock in ubuntu machine. happens when close vmware player , open suspended session. example if close vmware player running ubuntu @ 4:15 pm , restore @ 5:45 pm, still shows 4:15 pm. (this not happen when shutdown ubuntu os.) i searched stackoverflow forum , found setting tools.synctime = true tools.synctime.period = 60 should resolve problem. change did not work me. pointers resolve issue helpful. i had same clock sync issue. installing vmware tools solves problem. but if doesn't help, can manually calling sudo ntpdate ntp.ubuntu.com every time open suspended session.

how generate random matrix not singular in matlab.? i know matrix determinant can used check this, after reading matlab determinant : "using det(x) == 0 test matrix singularity appropriate matrices of modest order small integer entries. testing singularity using abs(det(x)) <= tolerance not recommended difficult choose correct tolerance. function cond(x) can check singular , singular matrices." so if want generate big random matrix (axb) a=5000, b=5000 , how it??. a randomly generated matrix full rank (and hence invertible, if square) probability 1: a = randn(5000); you can check using min(svd(a)) , , verifying smallest singular value larger zero. this well-known fact, here's example paper if want one .

so have 2 images set fill screen - 1 @ 320x480 (iphone 3) , other @ 640x960 (iphone 4). img.png (320x480) img@2x.png (640x960) in interface builder, have img.png set fill view (it shouldn't filling iphone 4 view, though, right?), , when build , run, notably small. so, when opposite, setting img@2x.png img, giant blue question mark fills view. project still builds , image fills screen, pixelated if has been rescaled. shouldn't have been rescaled, though, higher resolution. now using... img.png (640x960) img@2x.png (320x480) i've tried switching file takes @2x suffix, has not helped either. smaller file taking @2x suffix, , setting image view img.png, shows way larger view canvas, way small when on phone. smaller file still having @2x suffix, tried switching view new img@2x.png , once again got oversized, pixelated question mark in ib , low res full-screen image when deployed phone. i made sure view size set 640x960 in size inspector. else shou

for example system.out.println("╚"); displays ?, same goes system.out.println("\u255a"); why doesn't work? stdout indeed support these characters don't it. see this question . when java’s default character encoding not utf-8 — case, seems, on windows , os x, not linux — characters fail encode converted question marks. can pass correct switch ( -dfile.encoding=utf-8 on terminals, don’t have windows box in front of me) jvm’s command line, or can set environment variable. portably determining should might impossible, if know run on win32 console, example, can choose charset explicitly encode characters before writing them standard output, or can directly write bytes need.
