what idiomatic way collect results in loop in r if number of final results not known beforehand? here's toy example: results = vector('integer') i=1l while (i < bigbigbignumber) { if (somecondition(i)) results = c(results, i) = i+1 } results the problem example (i assume) have quadratic complexity vector needs re-allocated @ every append. (is correct?) i'm looking solution avoids this. i found filter , requires pre-generating 1:bigbigbignumber want avoid conserve memory. (question: for (i in 1:n) pre-generate 1:n , keep in memory?) i make linked list this: results = list() i=1l while (i < bigbigbignumber) { if (somecondition(i)) results = list(results, i) = i+1 } unlist(results) (note not concatenation. it's building structure list(list(list(1),2),3) , flattening unlist .) is there better way this? idiomatic way that's typically used? (i new r.) i'm looking suggestion on how tackle type of problem. sugge

the glyphs in iconfont, custom web font in navigation in footer, not showing when viewed on iphone. ios 6.1.4 any idea why happening , how fix it? here screenshot of icons in footer not appearing: here link page happening the problem ios provides partial support font-feature-settings css property can use ligatures in ios safari adding text-rendering: optimizelegibility . following link ( http://clagnut.com/sandbox/opentype/ligatures ) shows text using font magenta common & discretionary ligatures on , other text common & discretionary ligatures off. if access link ios device see both texts equal. means ios not support ligatures font-feature-settings , why gyphs in typography not work on ios. to make work in ios, you'll have add text-rendering: optimizelegibility css. reference may "tomorrow’s web type today: fine flourish of ligature" . but, should read "is safe use css rule “text-rendering: optimizelegibility;” on text?" .

when studying programming 8085, 8086 , microporcessors in general have hexadecimal representation. ok binary numbers important in computers. how these hexadecimal numbers important? historical importance? it nice if point historical papers also. edit: how computers handle hexadecimal numbers? example happens in 8085 when hexadecimal number given input? hexadecimal has closer visual mapping various bytes used store number decimal does. for example, can tell hexadecimal number 0x12345678 significant byte hold 0x12 , least significant byte hold 0x78 . decimal equivalent of that, 305419896 , tells nothing. from historical perspective, it's worth mentioning octal more commonly used when working older computers employed different number of bits per word modern 16/32-bit computers. wikipedia article on octal : octal became used in computing when systems such pdp-8, icl 1900 , ibm mainframes employed 12-bit, 24-bit or 36-bit words. octal ideal abbreviation of

how should using requirejs-text installed via bower? supposed put in baseurl wonder if use components/requirejs-text/ ? whats best practice? define path plugin in config: requirejs.config({ paths: { "text" : "components/requirejs-text/text" } }, and use in module documented on https://github.com/requirejs/text : require(["some/module", "text!some/module.html", "text!some/module.css"], function(module, html, css) { //the html variable text //of some/module.html file //the css variable text //of some/module.css file. } ); you can use technically use plugin without path definition in requirejs.config, propbably not best practice: require(["your_path_to_the_plugin_from_baseurl/without_js_at_the_end!some/textfile"], function(yourtextfile) { } );

ok, creating sort of dating service , have db requires field match against multiple other fields. need stored, can ignored , set maybes later viewing. know setting comma delimited field unwise, cannot figure out better way keep track of matches while being able categorize them separate columns later on. does have better way of doing without comma delimited field? how array? can store array of information in database. in php declare such: variable = array(); can deal variable array using loops, variable[index#], etc. hope helps!

i facing peculiar problem lib-linear package. have 2 levels (+1, -1). have 1 feature takes values $x_1$, $x_2$,..., $x_n$ n points. classifies giving positive weight $w*$ , cost c example. if stack $1$ previous feature make new feature vectors [1 x_i] i=1, 2, ...,n; new problem lib-linear gives following: weight vector [w_1 -w_2]; w_i>0 i.e. weights 1 w_1 , x w_2. cost c1 greater previous cost c. i understand new feature (1) has no variation throughout , hence weight should automatically go zero. it minimization problem should give w_1~0 cost c1 @ equal c. can help? since have constant input dimension, contribution in decision function constant. liblinear's decision function is f(x)=sign(w^t*x-rho) my guess new model corrects term (due non-zero w_1) through rho. can't have idea why w_1 not minimized zero, though. predictions of both models equal?

i'm new in python, know, can file ext path use: os.path.splitext(path)[1][1:] this works well, seems not quite beautiful, want ask: there better way file ext the readable way be name, ext = os.path.splitext(path) ext = ext[1:] though that's no longer single expression. if want single expression, wrap in function: def extension(path): name, ext = os.path.splitext(path) return ext[1:] be aware on systems, files may have empty extension, e.g. >>> os.path.splitext('ham.') ('ham', '.') and you're treating same files no extension @ (just ham ). usually, difference doesn't matter, in cases might, why splitext works way does.
