essentially problem finding easy way create image file array. my problem unparsing cups raster files images. cups rgb raster file header 1800 bytes. if input width , height can read raster array contained in file correctly photoshop in mac order, interleaved 16 bit data 00rrggbb. have written utility extracts width , height header. i'd write command-line utility takes width, height , file-name inputs, truncates first 1800 bytes off raster file, , creates tiff or bmp or whatever easiest write image array contained in rest - well-known image format do. program should c or python, run under mac, linux. for python, pil tool task. use putdata() (search link putdata) method on image objects put pixels list image.

i had talk on #ruby-lang channel other day @@class_variables . started when user asked what's best way keep track of connected users server (i simplified it, that's gist of it). so, suggested: class user @@list = {} #assuming wants users type of id def initialize(user_id, ...) @@list[user_id] = self #... end end however, somone said use of global state here considered bad practice. i understand why global state bad relies on multiple back-ends, because global part of global state stops being global, , becomes localised 1 back-end. or interferes dependency injection. i can't think of other reason why bad, though. and, if concurrency ever becomes issue (there's need multiple back-ends), can update code use redis (or similar). also, found this question on programmers.sxc , doesn't me understand why above code considered bad? also, alternative? why bad? global state bad couple of reasons didn't mention: it's unreliab

i'm not able figure out how assign function scroll event in dojo. have seen other post using dojo's connect, i've been unable work, , if could, project's using behaviours as possible, i'm trying work first... the puzzling thing me, i've looked around on dojo's website bit, , references i've seen scroll events mention them aside. on http://dojotoolkit.org/reference-guide/1.9/quickstart/events.html#connecting-to-a-dom-event example, there's list of events can connect-ed to, , scroll isn't on them. mouse wheel + down are, not cover possible actions might lead scroll occurring. i've used jquery's scroll event before, , nice , simple. fact i'm having trouble figuring out scroll event in dojo bothers me little. this i've tried: var mybehavior = { window : { scroll: function(e) { console.log("i'm scrolling"); } } }; behavior.add(mybehavior); behavior.apply(); that loads withou

i know commonly refactor code back-end improve it's speed, security or make more readable next person takes on project, refactor html , css? since markup languages doesn't seem trivial, besides wiping off few bytes of code vs time input looking alternatives doesn't seem worth effort, if working on tight deadline. there innumerable things can increase or decrease page performance. optimisation though, should start people seeing problems or slowdown. on broader level, reducing payloads smallest possible size makes big difference. involves gzip, caching, , minification. can rewrite code thousand times won't end smaller if @ if use gzip , minify css — don't minify html it's prone rendering issues. on finer level, specific css features such resizing large images , implementing lots of browser-generated gradients , shadows can bring performance down significantly. if you're noticing sluggishness when scrolling things need focus on. 1 image that

i'm doing project in python involves lot of interactive work persistent dictionary. if weren't doing interactive development, use contextlib.closing , confident shelf written disk eventually. stands there's no chunk of code can wrap within 'with' statement. i'd prefer not have trust myself call close() on shelf @ end of session. the amount of data involved not large, , happily sync shelf disk after each operation. i've found myself writing wrapper shelve i'm not strong enough python programmer identify correct set of dict methods i'd need override. , seems me if i'm doing idea, it's been done before. paradigmatically correct way handle this? i'll add using shelve because it's simple module, , comes python. if possible i'd prefer avoid doing requires (for example) pulling in complicated library dealing databases. i'm using winxp sp3, python 2.7.5 via anaconda 1.6.2 (32-bit), , running inside spyder. can tell looking @

i want create default dict using string. let's have word 'hello': function return: {'h':{'e'}, 'e':{'l'}, 'l':{'l', 'o'}} i tried creating defaultdict(set) first in order rid of duplicates, i'm not sure how obtain key's value next letter in string (if makes sense?) def next(s): x = defaultdict(set) in range(len(s)-1): x[i].add(s[i+1]) #this part unsure return x this returns me error saying how str object has no attribute 'add'. your code works fine: >>> collections import defaultdict >>> def next(s): ... x = defaultdict(set) ... in range(len(s)-1): ... x[i].add(s[i+1]) ... return x ... >>> next('hello') defaultdict(<type 'set'>, {0: set(['e']), 1: set(['l']), 2: set(['l']), 3: set(['o'])}) perhaps running code uses defaultdict(str) accident? you want use s

in scikits audiolab, i'm trying split audio's 2 channels in 2 different file, , observed read_frames method numbers looks list not exactly. , documentation not explicitly mention data type. looks like, [[-0.25283813 -0.05990601] [-0.28274536 -0.06542969] [-0.30093384 -0.06890869] ..., [ 0.21939087 0.36206055] [ 0.22756958 0.36981201] [ 0.22592163 0.37960815]] what return type of read_frames()? first, without documentation can print type(returned_value) , discover in case numpy.ndarray instance. of it, two-dimensional 1 lots of rows , 2 columns. and documentation does mention type explicitly: read given number of frames , put data numpy array of requested dtype.

i cloned repository on local machine , did git remove on 1 of files , pushed changes github repository. question how restore file on original github repository? if can find previous commit abcd has deleted file, can use git checkout abcd file-to-restore to restore it. you'll need commit file again.

just wanted see if others thought following behaviour in matplotlib plot_date buggy, or if it's should put with. i have multi-panel plot set sharex facilitate zoom/pan on axes, , plot time series data in both panels. however, in second panel, of data happens invalid (in example mask it). from matplotlib.pyplot import figure,show datetime import datetime,timedelta numpy import sin,cos,linspace,pi,ma,array fig=figure(figsize=(16,9)) ax1=fig.add_subplot(211) ax2=fig.add_subplot(212,sharex=ax1) # xdata seconds xdata=linspace(0,9999,10000) tdata=array([datetime(2000,1,1)+timedelta(seconds=ss) ss in xdata]) data1=ma.masked_array(sin(pi*xdata/300),mask=false) data2=ma.masked_array(cos(pi*xdata/300),mask=true) ax1.plot_date(tdata,data1,marker='',color='r') ax2.plot_date(tdata,data2,marker='',color='b') show() i'd expect (prefer) show blank panel, not fail , give me long unhelpful traceback. expected behaviour? notes: this script fails

forgive me if question repeat, i'm stuck code i've been working on. creating program myself create random teams of people, , i've been trying find easy way make inserted amount of teams. area suck on here: print("how many teams like?") numberteam = input("number: ") listnumber = 0 teams = [] while numberteam + 1: teams.append(team(str(listnumber + 1)) = []) i new coder, i'm sure besides obvious using expression variable there other mistakes, suggestions on easy way fix great! also if left out, please ask! (by way using python) try (i cleaned things bit): print("how many teams like?") numberteam = int(input("number: ")) # create dictionary, each team has emtpy list teams = dict([('team{}'.format(i), []) in range(numberteam)]) # following works # teams = {'team{}'.format(i):[] in range(numberteam)} you can access teams this: teams['team3'] # returns empty list the longhand a

whenever ctrl+shift+w (close tabs) in eclipse , start or open fresh project, warnings , errors in problems view persist (from previous projects in workspace open in past). how can let eclipse know want focus on current project only? this varies release, there filters dialog (try using down arrow in problems toolbar , choose "filter content"). can set scope "on element in same project". scope determined using current selection in 1 of navigator views (packager explorer, navigator, etc)

the same code in project has different execution duration same input parameters, varies 1ms 30ms. private void link(array values, area area){ values.add(area); array<area> children = area.getchildren(); (int i=0; i<children.size; i++){ area child = children.get(i); link(values, child); } } this lags inappropriate. can fix them? intermittent lags caused garbage collection.

looking @ ember.js documentation, rather vague when make use of ember.run() (my emphasis). normally should not need invoke method yourself. if implementing raw event handlers when interfacing other libraries or plugins, you should wrap of code inside call. from looking through source , reading posts on topic, understanding when call ember.run() , following occurs. the given callback run. the run loop algorithm executed, flushing queues , ensuring bindings synchronized, etc. i'm trying understand why recommended handle other libraries' events inside of call ember.run() . take following example create jquery ui slider , handle slide event. <script type="text/x-handlebars" data-template-name="index"> <div id="slider"></div> <h2>{{value}}</h2> <h3>{{valueprose}}</h3> </script> app = ember.application.create(); app.indexcontroller = ember.controller.extend({ actions: {
