is there way can set current_timezone in db2 database ? querying db2 "select current timestamp , current timezone sysibm.sysdummy1" 1 2 -------------------------- -------- 2015-05-13-22.02.23.714464 0. right current_timezone value 0 , set gmt want manually set pst (-80000). can please guide me steps ? the db2 database manager obtains time information operating system, you'd need set time zone via tz environment variable instance owner, restart instance.

it seems java's implementation of hashmap always places keys same bins (at least saw integer keys). i.e. hashing deterministic , in runs produces same value. have heard languages randomize insertions in bucket key stored unpredictable security reasons. why java keys same? this not true java 7, added unique hash seed each hashmap instance. there's more information on collections framework enhancements in java se 7 page. this mechanism removed in java 8 performance, , replaced alternative converts comparable keys (such string) balanced tree elide dos security problem. there's more information on collections framework enhancements in java se 8 page.

have practical question when have 2 (or more) data frames , want assign unique ids each matching observation within each , across both datasets e.g.: #1. create dataframe df1: a1 <- c(1, 1, 1, 1, 2, 2, 2, 2, 1, 1) b1 <- c(1, 5, 3, 2, 3, 4, 5, 1, 5, 2) c1 <- c("white", "red", "black", "white", "red", "white", "black", "silver", "red", "green") df1 <- data.frame(a1, b1, c1) df1 a1 b1 c1 1 1 1 white 2 1 5 red 3 1 3 black 4 1 2 white 5 2 3 red 6 2 4 white 7 2 5 black 8 2 1 silver 9 1 5 red 10 1 2 green #2. create dataframe df2: a2 <- c(2, 2, 1, 1, 2, 2, 2, 2, 2, 2) b2 <- c(3, 1, 3, 2, 1, 3, 4, 5, 3, 5) c2 <- c("black", "blue", "black", "white", "silver", "green", "green", "red", "blue", "white...

if randomly put in 2 numbers (first number smaller), how use for-loop add numbers between , itself? ex: first number: 3 second number: 5 the computer should give answer of '12'. how do using for-loop? simple loop across range defined: puts "enter first number: " first = gets.to_i puts "enter second number: " second = gets.to_i total = 0 in (first..second) total += end puts total note if don't enter valid number, converted 0. assumes second number larger first.

i have buffer download on node.js server dropbox. i'd send buffer (or convert file , send it) client, , have begin downloading on client side. missing here? var client = dboxapp.client(req.session.dbox_access_token); client.get(req.body.id, function(status, data, metadata) { // do here? }) here's angular (uses promise). when console.log(response object includes buffer). function(id, cloud){ return $http.post('/download/'+cloud, {id: id}).then(function(response){ console.log(response) }, function(response) { return $q.reject(response.data); }) } it looks dbox module you're using has stream() option better suited file downloads. should make call metadata file's mime type. example: var middleware = function(req, res, next) { var client = dboxapp.client(req.session.dbox_access_token); var file = req.body.id; client.metadata(file, function(status, reply) { res.setheader('content-disposition', ...

i want generate llvm bitcode large number of c source files have compilation database . there way invoke clang such reads compilation database , uses appropriate flags? background for toy programs, command generate llvm bitcode simple: clang -emit-llvm -c foo.c -o foo.bc however, source files in large projects require lots of additional compilation flags, including -i s , -d s , whatnot. i want write script iterates on large number of source files , calls clang -emit-llvm ... on each generate llvm bitcode. difficulty each clang -emit-llvm ... command has have flags specific source file. have compilation database these source files, captures flags needed each individual source file. is there way make clang -emit-llvm ... aware of compilation database? one solution i've thought of parse compilation database myself , find appropriate entry each source file, , modify command entry (a) include -emit-llvm , (b) change -o foo.o -o foo.bc , , run command. might work,...

i'm working on project want sideways stacked bar chart. needs written in javascript, , best library i've found need canvasjs. in chart i'm creating, colors used in stacked bar not distinguishing different bars, colors have meaning. because of this, if specify color each part of stacked bar independently other bars. here page specific kind of chart want on page, example provide has 5 bars, each colors blue, red, purple, green, light blue. 5 bars, colors go in same order. able mix order independently, have bar goes red > green > yellow, 1 goes green > yellow > red, etc. if know how this, or if know of graphing library in, appreciate help. thanks! it looks matter of adding color attribute each datapoint individually: { x: new date(2012, 01, 1), y: 71, color: "red" } ...which can done each datapoint way like.
