i have loop of write(2) arbitrary amount of data + eol , fsync(2) appending file line line. can crash of process leave me file has half of data write(2) call written file? theory if os calls fsync occasionally, there might coincidence of happening during call write(2) leaving file half of line written, without ending new line. yes. without crash, might have partial line written write call might not write data passed -- might return short write.

folks, i trying create column chart using google chart api , having lots of issue in getting y-axis line. i understand x-axis string why vertical grid line not coming y-axis line must come. marking in red of line not coming. i have following code. function drawchartsecond(resp) { var data = new google.visualization.datatable(); data.addcolumn('string', 'activity'); data.addcolumn('number', 'hours'); data.addrows([ ['work', 11], ['eat', 2 ], ['commute', 2 ], ['watch tv', 2], ['sleep', 7] ]); var options = { title : '', legend: { position: 'right', alignment: 'center' }, tooltip: { ishtml: true }, haxis: { title: 'activity', titletextstyle: { color: 'black', font...

following on this question : there 64kb bytecode limit on java methods. what benefit provide compiler? gcc happily compile multi-megabyte c methods -- what's reasoning behind design decision? just, suggested in this question , limit poor programming practices, since 64kb methods massive? or there specific benefit limit being 64kb rather other number? offsets in method bytecode 2 bytes long (called "u2" in class file format specification). maximum offset can expressed u2 64kb. the offsets appear in actual instructions, such if* bytecodes, followed 2 bytes containing offset delta of branch. also, other class file attributes stackmaptable , localvariabletable , exceptions , others contain offsets bytecode. if offsets u4, methods longer, all class files larger. it's trade-off.

i using raphael make manipulations in svg. in order save svg image use canvg render svg in canvas. transformations of images inside svg rendered in canvas not right. canvg uses native transform() method of html5 apply transformations using below code in line 571 of canvg. ctx.transform(this.m[0], this.m[1], this.m[2], this.m[3], this.m[4], this.m[5]); but results in transformations rotations , scaling done around origin of image. in raphael transformations applied around center of image. so possible apply transformations happens around center of image? you can make own function makes transformations happen around center of image given image's center points . the theory around making things transform center follows : translate image <-x,-y,-z> , (x,y,z) image's center. do transformation want do translate image <x,y,z> . (you're returning original position now)

link_to cleverly figure out type active record object , create link it's show route. how can find path unknown object type. ie. i'd like <div id="target_path" data-path="<%= path_to @my_polymorphic_instance %>" ></div> implementing might like def path_to obj url_for( :controller => obj.class.to_s.underscore.pluralize, :action => :show, :id => obj.to_param, :only_path => true ) end whats better way? the polymorphic_path should trick: <div id="target_path" data-path="<%= polymorphic_path @my_polymorphic_instance %>" ></div> in fact, it's source code similar path_to supposition.

i trying build app allows user combine 2 uiimages, i've got no problem using core graphics. user able pan , resize photo in view , combining result of views in image context. the size of combined photo small saving visible portion of image in view in. avoid shrinking photo , scaling up, have provide view user alter photo , apply changes (at correct scale) full size photo? i appreciate help, if above confusing can provide code example, trying see if i'm heading down right road or if there better way... thanks to avoid shrinking photo , scaling up, have provide view user alter photo , apply changes (at correct scale) full size photo? yes, if shrink image start (to display user , allow user manipulations) must not throw away original , scale shrink image again. must keep original , operate upon it. otherwise, lose lots of pixels forever. however, why bother? display shrink the way image drawn you. if show large image in uiimageview, using aspect fit mod...

my purpose combine multiple 2d list in order such as: a = [[1,2],[3,1]] b= [[3,6],[2,9]] c = [[5,1],[8,10]] expected: [[1,2,3,6,5,1],[3,1,2,9,8,10]] following other's advice site, tried use collections module code below: from collections import counter = [[1,2],[3,1]] b= [[3,6],[2,9]] c = [[5,1],[8,10]] d = [[k,v] k,v in (counter(dict(a)) + counter(dict(b))+ counter(dict(c))).items()] print d however, result [[1, 2], [3, 1], [3, 6], [2, 9]] not expected. do have idea solve problem? maybe if there function or module consider axis combine lists. you can use zip , list comprehension : >>> = [[1,2],[3,1]] >>> b = [[3,6],[2,9]] >>> c = [[5,1],[8,10]] >>> [x+y+z x,y,z in zip(a, b, c)] [[1, 2, 3, 6, 5, 1], [3, 1, 2, 9, 8, 10]] >>>

i've got new model tons of attributes. when #save ing expect backbone #post because id null, works correctly. $ = require('jquery') - = require('underscore') model = new backbone.model({ id: null, name: "tom", cat: false, dog: true, //... many more attrs whiskers: false, tail: true }); now want send small subset of attributes server on post. with jquery can write this: data = _.pick(model.attributes, 'name', 'dog', 'tail'); $.post(model.url(), data); how can backbone? i did sync below, felt wrong. data = {} data.attrs = _.pick(model.attributes, 'name', 'dog', 'tail'); model.sync('create', model, data)

i creating abstract quilt square. have subclass of either abstractquiltsection or abstractgraphicalquiltsection , class extend 1 of these classes. since creating text based quilt section, extended abstractquiltsection class. there 9 abstract methods in abstractquiltsection: **public abstract string line1...line9 (int width)** each of these methods return string. length of string should width parameter. i.e. if width 12, string returned should 12 characters long. line1 method returns first line of quilt section, line2 method returns second line, etc. here confused: each text based quilt section 9 characters high (i.e. take 9 lines), width may vary. when quilt drawn, line1, line2, line3…etc. methods called figure out characters output. a sample quilt section width of 12 (containing quote shakespeare) might be: ............ .to......... ......thine. ...own...... .....self... ..be........ .....true... ............ shakespeare. i have create subclass of abstrac...
