i wonder 1 of personal projects development goes further forward how should organize files ( images, videos, audio files ) uploaded users onto aws's s3/gce cloud storage, i'm used see these kinds of url below; facebook fbcdn-sphotos-g-a.akamaihd.net/hphotos-ak-xft1/v/t1.0-9/11873531_1015...750483_5263546700711467249_n.jpg?oh=b3f06f7e...b7ebf7&oe=56392950&__gda__=1446569890_628...c7765669456 tumblr 36.media.tumblr.com/686b47...e93fa09c2478/tumblr_nt7lnyp3ld1rqbl96o1_500.png twitter pbs.twimg.com/media/cmimixsv...aczem.jpg does these random characters carry kind of meaning? or they're "uuids"? there performance/organization issue in using, instance kind of url below? content.socialnetworkx.com/usery/post/customname_dinosaurs.jpg edit: let clear i'm considering millions of files. for s3, see performance considerations page talks object naming. specifically, if plan upload objects @ high rate, should avoid sequentially named object...

questions consider following 32-bit , 64-bit values: uint32_t ival32 = 0x ab cd 12 34; uint64_t ival64 = 0x ab cd 12 34 56 78 ca be; how determine whether ival32 contains 16-bit (word) value? let's 0xcd12 . how determine whether ival64 contains 16-bit (word) value? let's 0x3456 . update 1 (added later) 0xcd12 word value checked might anywhere in ival32 in every word boundary. 0x3456 word value checked might anywhere in ival64 in every word boundary. update 2 (added later) i admit ridiculous mistake in question. in previous example, word values checked not in word boundaries in ival32 , ival64 . therefore, correction are: for ival32 , word value checked can either 0xabcd or 0x1234 . thus, example, 0xcd12 shouldn't found in ival32 . for ival64 , word value checked can 1 of following: 0xabcd or 0x1234 or 0x5678 or 0xcabe . thus, example, 0xcd12 or 0x3456 or 0x78ca shouldn't found in ival64 . remarks solutions intended us...

so have array each cell of array containing specific function. var randomly = [ function(a) { return * - a; }, function(a) { return (a - 2) * (a - 1) * (a - 1); }, function(a) { return * + a; }, function(a) { return % 3; } ]; i'm creating function that takes input value (a) entire array , goes through each array cell individually, solves function. however, result of function becomes next function's input value. initial input value first function, , next function's input falue previous function's result. to this, created loop... var thefunction = function (input, queue){ (var = 0; < queue.length; i++){ queue[i](input); } so, here i'm stuck... how can call specific array along input value? used queue[i](input); not sure if that's valid. on appreciated. you're close, "chain" functions, you'll need store return values, can re-use them: var thefunction = function (input, queue) { var result = inpu...

i trying write equation inside chunk. need use '\sum' r not accept it. got error: '\s' unrecognized escape in character string i tried packages without success. how can bay pass escape character? here example: \documentclass{article} \begin{document} <<results='asis',echo=false>>= #library(lazyweave) #library(hwriterplus) #hwritelatex(as.latex("\bar{r}_{i}=\frac{\sum_{t=1}^{t}{r_{i,t}}}{8}")) # cat('\bar{r}_{i}=\frac{\sum_{t=1}^{t}{r_{i,t}}}{8}') #cat("$$","\bar{r}_{i}=\frac{\sum_{t=1}^{t}{r_{i,t}}}{8}","$$",sep="") cat("typically want our paragraphs left justified. expect see when reading.") @ \end{document} edit. read similar examples no 1 involved escape characters. you need double escape character. > cat('\\bar{r}_{i}=\\frac{\\sum_{t=1}^{t}{r_{i,t}}}{8}') \bar{r}_{i}=\frac{\sum_{t=1}^{t}{r_{i,t}}}{8}>

so have 2 serial numbers , 199 serials in between them: 899720101000105500 (first) 899720101000105699 (last) i need print first serial , 199 last serial. thing i've found +1 first serial every time loop runs , printing it. i've copied/pasted different parts , have: var lowend = 899720101000105500; var highend = 899720101000105699; var arr = []; while(lowend <= highend){ arr.push(lowend++); } is there max number length can store in variable? here's solution specific problem may come across this. make static parts of number (the digits don't change) string , use digits change (for me last 4) count , add string count , log it. var serialnumber = 5500; while(serialnumber <= 5699) { serialnumber = serialnumber + 1; var fullnumber = "89972010100010" + serialnumber; console.log(fullnumber); }
