i create horizontal ‘stacked bar’ type plot in date runs along x-axis , samples appear bars on y-axis. in simple example below, have 3 samples (a, b, c) each containing 3 values (0, 1, 2). horizontal bar coloured based on value @ each time step along x-axis, end 3 horizontal bars (one each sample) run first last time point , contain series of blocks colours relate different values. for example, want value 0 blue, value 1 yellow , value 2 red: sample a, first 2 days of trace blue, next 2 days yellow, followed single blue , on…… example data: df <- structure(list(date = c("30/04/2011", "01/05/2011", "02/05/2011", "03/05/2011", "04/05/2011", "05/05/2011", "06/05/2011", "07/05/2011", "08/05/2011", "09/05/2011", "10/05/2011", "11/05/2011", "12/05/2011", "13/05/2011", "14/05/2011", "15/05/2011", "16/05/2011", &q

i have windows application accessing dev database using datamodel.edmx , works fine. access stage environment database have added stagedatamodel.edmx. there 2 connection strings in app.config: , how switch between databases in app.config based on environment? thanks in advance! normally should other way around - create 1 ef edmx model , 2 (or more) configuration files every environment. at work, have 3 environments: release = production stage = before go live (copy of production, final tests) debug = new development, dev team tests for 3 environments, have 3 databases, (almost) similiar each other. create our model dev database. every project communicates database has 3 connection strings different credentials. in order achieve this, need to: 1) create different build platforms using visual studio configuration manager (in example, there 3 build configurations - dev/stage/release): 2) extract connection string configuration app.settings file. inste

i have table parent,child relationship. on table have list of members leafs in first table. have first table filtered members parents of member in second table, or members of second table. hope problem clear, if not please ask. database oracle 10g. let's have hierarchy in table th , in members table tm there 3 rows 'gc carl', 'pt mike', 'pt mary' (marked green). to find parents, grandparents etc. (marked yellow) need simple hierarchical query: select distinct id th connect id = prior pid start id in (select id tm) sqlfiddle demo if looking parents , need in hierarchical way then: select distinct id th connect id = prior pid , level <= 2 start id in (select id tm) (martin eliminated, because not parent member , absent in tm ). if not wanted should precise query, add sample input data , desired output.

can pycharm configured learn python itself? have pycharm setup right , i'm trying see possible set me learn more language. example, , simple example, lets created empty list: list = [] if highlight on [] or control-click on it, pycharm tells me nothing lists or brackets. possible set can official python documentation talks lists or indicates list in first place? see official python documentation not added pycharm's default external documents under pycharms settings. if add it, how pull objects, sequence types, methods , other things makes python tick? pycharm awesome ide , have believe possible set language easier learn when working in it. at time pycharm able provide library functions; doesn't have features providing on language features such list literals.

i using iis url rewrite 2.0 module create url points latest version of app. have configured follows: <rule name="latest" stopprocessing="true"> <match url="^latest(.*)" /> <action type="rewrite" url="1.1{r:1}" /> </rule> the intention if goes /latest/* of urls rewritten /1.1/* . example /latest/index.html should become /1.1/index.html . this working when request file, example: /latest/index.html - works /latest/js/app.js - works however not work: /latest since index.html default document, expect rewrite /1.1/index.html , in fact seems redirect . example, if type following in browser address bar: http://<domain>/latest and press enter, changes to: http://<domain>/1.1 as if redirected. still works, don't want url change (hence why i'm using rewrite rather redirect ). idea why? there wrong rule? this problem you're experiencing: iis generate

update: please @ second query, more representable example i'd create query uses different subqueries each column. subqueries based on list obtained outer query. for example: consider tablea table 30 columns , 5 million records select a, b, c, (select count(a) values (r = 12 , u = 'to') or (r = 16 , u in ('tb', 'tu')) first, (select count(a) values (r = 16 , u = 'te') or (r = 76 , u in ('te', 'tg')) second, (select count(a) values (r = 564 , u = 'hg') or (r = 788 , u in ('vd', 'bf')) third, (select count(a) values (r = 383 , u = 'rt') or (r = 35 , u in ('gr', 'ez')) fourth tablea values i know query not execute since can't call values subqueries, there solution make query run fast? in subqueries, i'd need join table, still possible use values, or have subquery on tablea again? following query more representable example: select col1, col2, (select count(col3)

there 2 levels of cache l1 , l2. if there cache miss on both levels, data being read memory. during reading data main memory, data first entered l2 , l1 cache first , processor reads data l1 cache or updation l1 , l2 , read processor happen simultaneously? i believe depends on hardware implementation. think depends on whether or not write-through or write-back cache. write through have same data @ levels because updates @ same time. put write buffer written cache, in case happen @ same time read. if there no write buffer, processor might stall allow cache updated.

in test have nsarray several objects. must pass same test. is there better or more elegant way express doing for-in , applying same macro each element? that's judgement call, consider -indexesofobjectswithoptions:passingtest: , maybe -enumerateobjectsusingblock: alternatives.

i new in python. scan ip-addresses in python , want read file ip-addresses in different notation cidr or ranges , script should extract ip cidr/ranges individual ip-addresses. file_in = open("test.txt", "r") file_out = open("ip-test2.txt","w") = 1 line in file_in: #take line , if individual ip , if not make block of ip- addresses , write them new file_out file_out.write(str(i) + ": " + line) = + 1 file_out.close() file_in.close() any idea how? or tool use that? i think you'll find python-iptools package you're looking for. so: with open("test.txt", "r") file_in: ips_and_ranges = iprangelist(file_in.readlines()) open("ip-test2.txt","w") file_out: ip in ips_and_ranges: file_out.write(ip) assuming file_in reasonable size, otherwise might need read in chunks. update: initial code needed "splat" unpack list args, , remove newlin

we have made changes 1 file in 2 branches. here file commit history on branch a: and here commit history of same file on branch b: now when merge branch branch b, end exact same commit history branch a. commit 56dfe991 has gone missing: obviously, disturbing. since don't know causing this. have idea? there no such thing "file commit history" in git. there's history, , files. the history considered @ git repository granularity, i.e. each commit has set of parents. see when run git log , or more visual output git log --graph --oneline --decorate . now, can ask git filter history on per-file basis, e.g. git log -- file . hides commits not touch file, but history simplifications hide commits not contribute file history. documented in details in "history simplification" section of git log's documentation . essentially, when reaching merge commit, if 1 of parent of merge commit not introduce change file, parent ignored. as result,

it useful leave low-level debug/trace logging statements in critical paths can enabled runtime configuration. idea never turn such logging on in production (it cripple performance) can turn on in production environment (e.g. production system taken offline debugging or test system set production system.) this type of logging has special requirement: cost of hitting disabled log statement on critical path must very low: ideally single boolean test. in c/c++ log macro not evaluate of arguments until has checked flag. if enabled call helper function format & deliver log message. so how in go? using io.discard log.logger non starter: formats log message every time before throwing away if disabled. my first thought type enabledlogger struct { enabled bool; delegate *log.logger;... } // implement log.logger interface methods as: func (e enabledlogger) print(...) { if e.enabled { e.delegate.output(...) } } this close. if say: myenabledlogger.printf("foo %v: %v

(azure, amazon, everlive etc). here need learn how manage 1 before using it.
