jetty - Solaris KSSL and a Java web server -

i'm trying setup solaris kssl proxy (http://www.c0t0d0s0.org/archives/5575-less-known-solaris-features-kssl.html) frontend jetty web server.

i'm able create kssl work apache web server kssl redirects incoming ssl traffic port 443 apache web server listening on port 28080.

however same configuration not work when jetty listening on port 28080. verified kssl requests not reach jetty or @ to the lowest degree cannot see them in access log. furthermore if set simple java class listens on server socket, kssl cannot redirect requests it.

my question pre-requisites web server in order able requests kssl ?

best regards, lior

there 2 mutual gotchas when working kssl.

the first apache listening ip has same ksslcfg command. if have hear 123.123.123.123:28080 in httpd.conf file, must utilize ksslcfg command same ip. cannot have listening on (*) , list ip in ksslcfg, or hear on ip , leave out ip on ksslcfg. whatever netstat shows listening on port 28080 must match ip used in ksslcfg (or don't utilize ip listening on *)

the sec must operations in order:

ksslcfg restart apache

it doesn't not work if ksslcfg run without restarting apache afterward.

i've seen many people on web testing localhost in ksslcfg command. won't work unless had localhost hear ip in apache configuration.

deployment - Symfony2 + GitFlow + Capifony + Capistrano-ext -

i'm developing website using symfony2 , gitflow. have 2 external servers called 'development', 'staging' , 'production' , central git repository on github.

i'm looking utilize capifony to:

deploy 'develop' branch changes development server. deploy releases/hotfixes etc staging test deploy 'master' branch live 'production' server

i've been reading this page multistage deployment , far have installed capifony capistrano extension.

within /app/config/deploy.rb file have following:

set :stage_dir, 'app/config/deploy' # needed symfony2 require 'capistrano/ext/multistage' set :stages, %w(production staging development) set :application, "myapp" set :repository, "git@github.com:mycompany/#{application}.git" set :scm, :git set :keep_releases, 3

i've got separate /app/config/development.rb file following:

server 'server_ip - port number', :app, :web, :primary => true set :deploy_to, "/var/www/myapp/" #directory on server set :symfony_env_prod, "test"

however, if run cap development deploy error

the task `development' not exist

can explain 'task' refers to?

thanks

move require 'capistrano/ext/multistage' lastly line of deploy.rb or @ to the lowest degree move set :stages, %w(production staging development) before it.

Using gcc -c to generate .o files -

Using gcc -c to generate .o files -

so had create bit of code create list , various things it. print it, sort it, , see if value in it. did that, ran fine. i've got take functions , split them separate files, utilize gcc -c (which i'm not super sure i'm using correctly) .o files, plus .o test program. have utilize gcc link .o files executable. prompt says recognize .o's , realize how link them.

so here questions: why below code returning errors( in ways defined below)? , supposed writing command line link these guys?

so code follows: (first .h files, main .c file)

node.h

typedef struct node{ int data; struct node *next; struct node *prev; }node;

print.h

#include<stdio.h> #include"node.h" void print(node *pointer){ if (pointer == null){ return; } printf("%d ",pointer->data); print(pointer->next); }

init.h

#include<stdio.h> #include"node.h" int init(node *pointer,int find){ pointer = pointer->next; while (pointer != null){ if (pointer->data == find)//found find { printf("the info in list."); homecoming 1; } pointer = pointer->next;// search in next node. } //find not found printf("the info not in list."); homecoming 0; }

sort.h

#include<stdio.h> #include"node.h" void swap (node *x, node *y){ int temp = x->data; x->data = y->data; y->data = temp; } void sort(node*pointer){ int i; while (pointer->next != null){ if (pointer->data>pointer->next->data){ swap(pointer,pointer->next); } pointer = pointer->next; sort(pointer); } }

list.c

#include<stdio.h> #include<stdlib.h> #include"node.h" #lnclude"print.h" #include"sort.h" #include"init.h" int i; node *p; node *n; void insert(node *pointer, int data){ //go through list till ya find lastly node while (pointer->next != null){ pointer = pointer->next; } //allocate memory new node , set info in pointer->next = (node *)malloc(sizeof(node)); (pointer->next)->prev = pointer; pointer = pointer->next; pointer->data = data; pointer->next = null; } int main(){ //start used point first node //temp lastly node node *start, *temp; int z; start = (node *)malloc(sizeof(node)); temp = new; temp->next = null; temp->prev = null; (z = 0; z < 10; z++){ insert(start,(3*10) - z); } init(start,12); init(start,3); init(start,27); init(start,7); print(start); sort(start); print(start); }

now code ran fine when together, exception of node.h (that separate file). .h files compile perfectly, when seek compile .c file returns errors claiming trying redefine node in each .h file. because including in each .h file?

i getting errors trying pass inappropriate arguments init function, not seem case. might on looking things.

thank in advance help.

edit: changed variable in main new start errors when typing "gcc list.c"

in file included init.h:2:0, list.c:4: node.h:1:16 error: redefinition of'struct node' node.h:1:16 note: defined here node.h:5:2 error: conflicting types 'node' node.h:5:2 note: previous declaration of 'node' here in file included sort.h:2:0; list.c:5: node.h:1:16 error: redefinition of'struct node' node.h:1:16 note: defined here node.h:5:2 error: conflicting types 'node' node.h:5:2 note: previous declaration of 'node' here list.c: in function 'main': list.c:41:1: warning: passing argument 1 of 'init' incompatible pointer type[enabled default] init.h:4:5: note: expected 'struct node *' argument of type 'struct node *'

(and there errors each of separate init calls in main)

list.c:45:1: warning:passing argument 1 of 'print' incompatible pointer type [enabled default] print.h:3:6: note expected 'struct node *' argument of type 'struct node *'

(and there 1 sec print function)

put inclusion barriers in .h files. eg, sort.h

#ifndef include_sort_h #define include_sort_h // contents of file #endif

edit

actually looked @ code more closely. have defined functions in .h files not thing do. see no reason separate separate files @ all.

so combine them single file , compile with:

gcc -o list -wall list.c

if want separate files, set functions c files , construction , prototypes .h file (which include each c file). compile , link using like:

gcc -o list -wall list.c node.c main.c

c gcc linked-list

how to store a byte [] into a single variable in android/java -

how to store a byte [] into a single variable in android/java -

i have string str = "admin:admin"

i want convert in ascii.

i have tried str.getbyte("us-ascii"); returning me byte[] array (i.e [97, 100, 109, 105, 110, 58, 97, 100, 109, 105, 110]). want ascii value in single string variable. how can this.

simple want string strascii = "971001091051105897100109105110"

is possible?

i tried this

stringbuilder builder = new stringbuilder(); (int i=0; i<=b.length; i++) { builder.append(b); } string result = builder.tostring();

but returning me this

[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0

what this?

try looping stringbuilder:

stringbuilder builder = new stringbuilder(); (byte b : arr) { builder.append(b); } string result = builder.tostring();

you could, of course, same thing string concatenation, using stringbuilder explicitly faster lots of little appends.

ASP.Net MVC4 with Razor - Best and correct way to acces controler methods in views -

ASP.Net MVC4 with Razor - Best and correct way to acces controler methods in views -

i have been working asp.net new asp.net mvc 4 razor concept. question might basic appreciate every help couldn't find definite reply days (or looking wrong things). question is: how access controller method within view without using index method?

the scenario:

i have database store values date, cost etc ... (variables defined in model.

i have controller thats sets view index

i have view shows indexpage values of info base.

i want sum values of cost colum dont want store result in db. in understanding access db via method in controller class , phone call method in view.

to larn step step defined fixed value in controller see how show value in view.

the code:

model: [range(1, 100)] [datatype(datatype.currency)] public decimal cost { get; set; } // amount of entry controller: public actionresult index() { homecoming view(db.amounts.tolist()); } public actionresult showsumofallprices() { //for testing db not called yet. query must defined , result written variable within mehod viewbag.price = 2; homecoming view(); } view: @*testmethod displaying sumprize (first wit test result) via controler*@ <table> <tr> <td>hallo @viewbag.price</td> </tr> </table>

the result not shown long don't define method content of showsumofallprices() (in controller class) in index() method.

the question is: result of method in view visible if define within index() method in controller or can write method did , phone call in view? working if c&p logic of showsumofallprices() index(). don't think need define in index method. if so, big , fat method. far see there 3 possible ways not might "nice" or working:

define in index() method. define other methods phone call them in index method because way display within view , not using model because dont want store info in db i can define other methods , straight phone call them in view without having new page result of method shown under content of currend index page.

i hope question understandable , question not asked mine before.

define in index() method.

controllers not meant hold logic.

define other methods phone call them in index method because way display within view , not using model because dont want store info in db

don't define other methods in controller itself. create other classes , phone call methods in index() or suitable controller method. , if want display info in view , model best choice, can store info in viewbag

i can define other methods , straight phone call them in view without having new page result of method shown under content of current index page.

if want fetch result of methods in same view can case[might using same kind of ajax] if want render other page , might bad idea.

the best thing can declare class required function single responsibility principle , utilize class operation in method want have results in.you can access controller methods using ajax , jquery, google out bit , own.

hope helps.

java - Clojure Performance For Expensive Algorithms -

java - Clojure Performance For Expensive Algorithms -

i have implemented algorithm calculate longest contiguous mutual subsequence (not confused longest mutual subsequence, though not of import questions). need squeeze maximum performance because i'll calling lot. have implemented same algorithm in clojure , java in order compare performance. java version runs faster. my question whether there can clojure version speed level of java.

here's java code:

public static int lcs(string[] a1, string[] a2) { if (a1 == null || a2 == null) { homecoming 0; } int matchlen = 0; int maxlen = 0; int a1len = a1.length; int a2len = a2.length; int[] prev = new int[a2len + 1]; // holds info previous iteration of inner loop int[] curr = new int[a2len + 1]; // used 'current' iteration of inner loop (int = 0; < a1len; ++i) { (int j = 0; j < a2len; ++j) { if (a1[i].equals(a2[j])) { matchlen = prev[j] + 1; // curr , prev padded 1 allow assignment when j=0 } else { matchlen = 0; } curr[j+1] = matchlen; if (matchlen > maxlen) { maxlen = matchlen; } } int[] swap = prev; prev = curr; curr = swap; } homecoming maxlen; }

here clojure version of same:

(defn lcs [#^"[ljava.lang.string;" a1 #^"[ljava.lang.string;" a2] (let [a1-len (alength a1) a2-len (alength a2) prev (int-array (inc a2-len)) curr (int-array (inc a2-len))] (loop [i 0 max-len 0 prev prev curr curr] (if (< a1-len) (recur (inc i) (loop [j 0 max-len max-len] (if (< j a2-len) (if (= (aget a1 i) (aget a2 j)) (let [match-len (inc (aget prev j))] (do (aset-int curr (inc j) match-len) (recur (inc j) (max max-len match-len)))) (do (aset-int curr (inc j) 0) (recur (inc j) max-len))) max-len)) curr prev) max-len))))

now let's test these on machine:

(def pool "abc") (defn get-random-id [n] (apply str (repeatedly n #(rand-nth pool)))) (def a1 (into-array (take 10000 (repeatedly #(get-random-id 5))))) (def a2 (into-array (take 10000 (repeatedly #(get-random-id 5)))))

java:

(time (ratcliff/lcs a1 a2)) "elapsed time: 1521.455 msecs"

clojure:

(time (lcs a1 a2)) "elapsed time: 19863.633 msecs"

clojure quick still order of magnitude slower java. there can close gap? or have maxed out , 1 order of magnitude "minimal clojure overhead."

as can see using "low level" build of loop, using native java arrays , have type-hinted parameters avoid reflection.

there algorithm optimizations possible, don't want go there right now. curious how close java performance can get. if can't close gap i'll go java code. rest of project in clojure, perhaps dropping downwards java performance necessary.

edit: added faster uglier version below first one.

here take:

(defn my-lcs [^objects a1 ^objects a2] (first (let [n (inc (alength a1))] (areduce a1 [max-len ^ints prev ^ints curr] [0 (int-array n) (int-array n)] [(areduce a2 j max-len (unchecked-long max-len) (let [match-len (if (.equals (aget a1 i) (aget a2 j)) (unchecked-inc (aget prev j)) 0)] (aset curr (unchecked-inc j) match-len) (if (> match-len max-len) match-len max-len))) curr prev]))))

main differences yours: a[gs]et vs a[gs]et-int, utilize of unchecked- ops (implicitly through areduce), utilize of vector homecoming value (and "swap" mechanism) , max-len coerced primitive before inner loop (primitive-valued loops problematic, less since 1.5rc2 back upwards isn't perfect yet, *warn-on-reflection* not silent).

and switched .equals instead of = avoid logic in clojure's equiv.

edit: let's ugly , restore arrays swap trick:

(deftype f [^:unsynchronized-mutable ^ints curr ^:unsynchronized-mutable ^ints prev] clojure.lang.ifn (invoke [_ a1 a2] (let [^objects a1 a1 ^objects a2 a2] (areduce a1 max-len 0 (let [m (areduce a2 j max-len (unchecked-long max-len) (let [match-len (if (.equals (aget a1 i) (aget a2 j)) (unchecked-inc (aget prev j)) 0)] (aset curr (unchecked-inc j) (unchecked-int match-len)) (if (> match-len max-len) match-len max-len))) bak curr] (set! curr prev) (set! prev bak) m))))) (defn my-lcs2 [^objects a1 a2] (let [n (inc (alength a1)) f (f. (int-array n) (int-array n))] (f a1 a2)))

on box, it's 30% faster.

i know best template engine node.js. i'm using jade engine node.js.

the confusion arise after reading

https://github.com/baryshev/template-benchmark

please suggest me best

thanks.

there no best view engine. criteria best view engine based on actual needs template engine has realize , person(s) using it. lot of people love jade view engine, example, there many not consider because not syntax. priorities should follow simple:

syntax: syntax view engine has you? features: view engine have want (e.g. includes, variables, filters)? learning: hard learn? if have designers, understand it? tooling? community: there community, or reachable, can help problems? performance: view engine compile , cache? if not, really matter?

note view engines automatically fall compilation , caching when run node in production mode (node_env=production) should check out different flavours of view engines , decide on best according criteria of project (e.g. jade, handlebars, ejs, gaikan).

update: looked @ benchmarks , decided merge own view engine (gaikan). fork can seen @ address https://github.com/deathspike/template-benchmark including results. if performance, adds valuable option, recommend stick priorities listed above.

c# - How to connect a Button to the Checkboxes in a GridView, and delete the selected rows from the GridView(ticked via CheckBoxes integrated in GridView)? -

i have created gridview containing info extracted textbox. have "delete link" on gridview delete row gridview if required.

now want create changes it. instead of "delete link" on gridview, want checkboxes on each row of gridview. outside gridview, there should button. on clicking button, rows selected via checkbox on gridview should deleted.

what changes has made below code implement functionality? please specify changes clearly.

restricting sed command -

i have variables needs modified minutes %m added. know sed command , working expected.

# cat mysed.txt myfirstfile="comany$mydb`date +'%d-%b-%y-%h'`.sql" # sed -i 's/\%h/\%h-\%m/' mysed.txt # cat mysed.txt myfirstfile="company$mydb`date +'%d-%b-%y-%h-%m'`.sql"

but if run same sed command again, add together %m 1 time again follows.

# sed -i 's/\%h/\%h-\%m/' mysed.txt # cat mysed.txt myfirstfile="company$mydb`date +'%d-%b-%y-%h-%m-%m'`.sql"

i need sed command should add together minutes %m 1 time if sed command executed twice (by mistake)

# sed -i "s/%h'/%h-%m'/" mysed.txt

this should work. way replacement if there quote mark next %h.

C# change formatting for a single DateTime -

C# change formatting for a single DateTime -

i creating datetimes used 3rd party library (on have of course of study no control). using 3rd party library write files, including datetimes creating.

i print dates in different format have no command on how datetime converted 3rd party , cannot alter civilization info between conversion of each datetime, neither can inherit datetime override tostring (like no 1 can).

is there way bind specific formatting datetime each phone call tostring method utilize formatting ?

datetime firstdate = new datetime(2013, 02, 07); //i datetime printed way: 2013-02-07 datetime seconddate = new datetime(2013, 02, 07); //i datetime printed way: thursday, feb 07, 2013 thirdpartylib.setfirstdate(firstdate); thirdpartylib.setseconddate(seconddate); thirdpartylib.printbothdate(); //this method convert both datetime in strings

with info given in question, way solve implementing own printing library.

or if 3rd party library extendable (i uncertainty since mentioned have no command on it) override printbothdate() suit needs.

Using Ruby to replace numeric data using simple hashmap -

Using Ruby to replace numeric data using simple hashmap -

i'm trying come simple way using ruby scramble (or mask) numeric data, in order create dummy info set live data. want maintain info close original format possible (that is, preserve non-numeric characters). numbers in info correspond individual identification numbers, (sometimes) keys used in relational database. so, if numeric string occurs more once, want map consistently same (ideally unique) value. 1 time info has been scrambled, don't need able reverse scrambling.

i've created scramble function takes string , generates simple hash map numbers new values (the function maps numeric digits , leaves else is). added security, each time function called, key regenerated. thus, same phrase produce 2 different results each time function called.

module hashmodule def self.scramble(str) numhash ={} 0.upto(9) |i| numhash[i.to_s]=rand(10).to_s end output= string.new(str) output.gsub!(/\d/) do|d| d.replace numhash[d] end puts "input: " + str puts "hash key: " + numhash.to_s puts "output: " + output end end hashmodule.scramble("56609-8 no pct 001") hashmodule.scramble("56609-8 no pct 001")

this produces next output:

input: 56609-8 no pct 001 hash key: {"0"=>"9", "1"=>"4", "2"=>"8", "3"=>"9", "4"=>"4", "5"=>"8", "6"=>"4", "7"=>"0", "8"=>"2", "9"=>"1"} output: 84491-2 no pct 994 input: 56609-8 no pct 001 hash key: {"0"=>"2", "1"=>"0", "2"=>"9", "3"=>"8", "4"=>"4", "5"=>"5", "6"=>"7", "7"=>"4", "8"=>"2", "9"=>"0"} output: 57720-2 no pct 220

given info set:

pto no pc r5632893423 ip r566788882-001 no pct amb pto no amb/call ip a566788882 1655543aachm ip 56664320000000 00566333-1

i first extract numbers array. utilize scramble function created create replacement hash map, e.g.

{"5632893423"=>"5467106076", "566788882"=>"888299995", "001"=>"225", "1655543"=>"2466605", "56664320000000"=>"70007629999999", "00566333"=>"00699999", "1"=>"3"}

[incidentally, in example, haven't found way insist hash values unique, relevant in event string beingness mapped corresponds unique id in relationship database, described above.]

i utilize gsub on original string , replace hash keys scrambled value. code have works, i'm curious larn how can create more concise. realize regenerating key each time function called, create work. (otherwise, create 1 key replace digits).

does have suggestions how can accomplish way? (i'm new ruby, suggestions improving code received).

input = <<eos pto no pc r5632893423 ip r566788882-001 no pct amb pto no amb/call ip a566788882 1655543aachm ip 56664320000000 00566333-1 eos module hashmodule def self.scramble(str) numhash ={} 0.upto(9) |i| numhash[i.to_s]=rand(10).to_s end output= string.new(str) output.gsub!(/\d/) do|d| d.replace numhash[d] end homecoming output end end # extract unique non-null numbers input file numbers = input.split(/[^\d]/).uniq.reject{ |e| e.empty? } # create hash maps each number scrambled value # using function defined above mapper ={} numbers.map(&:to_s).each {|x| mapper[x]=hashmodule.scramble(x)} # create regexp find numbers in input file re = regexp.new(mapper.keys.map { |x| regexp.escape(x) }.join('|')) # replace numbers scrambled values puts input.gsub(re, mapper)

the above code produces next output:

pto no pc r7834913043 ip r799922223-772 no pct amb pto no amb/call ip a799922223 6955509aachm ip 13330271111111 66166777-6

maybe this:

module hashmodule scramblekey = hash[(0..9).map(&:to_s).zip((0..9).to_a.shuffle)] def self.scramble(str); str.gsub(/\d/){scramblekey[$&]} end end puts hashmodule.scramble(input)

which gives:

pto no pc r6907580170 ip r699455557-223 no pct amb pto no amb/call ip a699455557 3966610aachm ip 69991072222222 22699000-3

http://jsfiddle.net/jpejf/1/

this little buggy, can spruce up, inquire for, needs more logic/polish.

the main code need @ is:

shapeslayer.on('mousedown', function(){ var userpos = stage.getuserposition(); var intersected = shapeslayer.getintersections(userpos); //gets shapes intersecting @ click position for(var = 0; < intersected.length; i++) { intersected[i].moveto(group2); // moves intersected shapes new grouping , need add together code when item moved new grouping keeps it's position } group2.simulate('dragstart'); //simulate dragging shapeslayer.draw(); }); shapeslayer.on('mouseup', function(){ //when mouse released var kids = group2.getchildren(); for(var = 0; < kids.length; i++) { kids[i].moveto(shapeslayer); //place in original container } shapeslayer.draw(); });

thanks in advance.

you're caching invocation of contactserviceimpl.findall method. test purpose can add together system.out.println("method invoked") in findall method. if cache works body of findall method should invoked once, next invocations should read value (result) cache shouldn't see "method invoked" on console.

don't utilize spring 3.1.0.m1 documentation different 3.1.0.release: http://static.springsource.org/spring/docs/3.1.0.release/spring-framework-reference/html/cache.html.

How to make jQuery equal column script run on window resize? -

How to make jQuery equal column script run on window resize? -

i'm running jquery script set equal height divs in row across multiple rows.

here's link extract of code i'm using http://jsfiddle.net/f8qhd/2/

for script i've used technique in post @ css tricks http://css-tricks.com/equal-height-blocks-in-rows/

can tell me how amend script window resized still works? @ moment, works on page load don't know how trigger based on window resize. script uses $(window).resize(function() {} ); i'm not sure why doesn't work?

any help apprecitated!

thanks.

i can't see doesn't work. set resize trigger works on load without duplicating instruction.

$(window).resize(function() { columnconform(); }).trigger('resize');

just 1 note - equalising elements causes window alter size , you're going nail problems when recurses few times before settles. solved adding timeout on equal heights function.

i wrote similar extension jquery. if you're interested it's here equal height rows fluid width elements

graphics - How to display part of an image using a for loop from a picturebox array -

there may simple reply have tried quite few things , nil seems work unless manually display images want utilize sub other pictures prepare later 1 time display these images. code follows

private sub updatestandardtoolbar() 'draws sprites pictureboxes dim bit new bitmap(gridsize, gridsize) dim dest_rect rectangle = new rectangle(0, 0, gridsize, gridsize) dim integer = 0 ' associate graphics object bitmap dim gr graphics = graphics.fromimage(bit) y integer = 0 standardnum.y x integer = 0 standardnum.x phone call getsrcrect(x, y) 'copy part of image. gr.drawimage(bmpstandardtile, dest_rect, src_rect, graphicsunit.pixel) 'display result. pb(i).image = bit += 1 next next end sub

the problem code pictureboxes (pb()) displays same image lastly 1 on image. standardnum.x , standardnum.y variables hold 3 , 1 respectively. bmpstandardtile image want re-create , dest_rect , src_rect self explanatory =). helps appreciated.

oh. found reply own problem after looking @ why pictureboxes displays same image. here code , how fixed if else has similar or same problem.

private sub updatestandardtoolbar() 'draws sprites pictureboxes dim bit bitmap dim dest_rect rectangle = new rectangle(0, 0, gridsize, gridsize) dim integer = 0 ' associate graphics object bitmap 'dim gr graphics 'for u integer = 0 maxpics ' bit = new bitmap(gridsize, gridsize) 'next y integer = 0 standardnum.y x integer = 0 standardnum.x bit = new bitmap(gridsize, gridsize) dim gr graphics = graphics.fromimage(bit) phone call getsrcrect(x, y) 'copy part of image. gr.drawimage(bmpstandardtile, dest_rect, src_rect, graphicsunit.pixel) 'display result. pb(i).image = bit += 1 next next end sub

the reply simple. silly me. forgot clear bitmap image not alter image lastly picturebox using.

bit = new bitmap(gridsize, gridsize)

anyway learnt mistakes =)

How do I design database for an application to deal with peculier needs of multiple countries -

How do I design database for an application to deal with peculier needs of multiple countries -

when developing multi-regional application, best practises handling things differences in currencies, working days , time differences when comes database design.

do create separate database each different region/country? have database mutual tables not affected country or regional peculiarity , create separate databases each peculiar region? put them in single database , have relational parent-child references countries table, currencies table, charges table etc.

there issue of business day varies every country , every year. agent charged penalties each business day have not banked collections, since different each country, how 1 deal when designing database.

i may have muddled question bit hope essence clear enough.

unless have other requirements dictate otherwise (e.g. scalability/redundancy), best way maintain in single db instance, define table collects countries interested in (along country-specific properties).

e.g.:

country-cd |country-name | currency | language | time-zone | region-cd italy eur met emea ... ... ... ... ... ... jp state of japan jpy jp jst far-east

and utilize country code part of key each other table may have country-specific content... prices:

item-id | country-cd | valid-from | valid-to | amount x unit 950595 | | 03-may-2013 | 31-dec-2099| 23.56 950595 | jp | 01-feb-2013 | 12-aug-2013| 2643.00 950595 | jp | 13-aug-2013 | 31-dec-2099| 2810.00

so same item priced @ 23.56 euros in italy, , instead sold 2643 yen in jp, feb.1st aug.12th, , increment in cost 2810 yen.

couple of caveats

i have used iso codes country , money. should robust plenty avoid problems in future. love of god not utilize application-specific codes things states or currencies. if designing little portion of world, like, dunno... "german speaking countries" (germany, austria, part of switzerland) resist temptation utilize things ger/aus/swi or not standard. time zones horribly hairy manage. set in same table country illustrate kind of info should associated country entry, in reality countries span more 1 time zone (ru, us) , hence need more sophisticated schema. on top of point (2) above, if application lives in single-instance db have decide rule how time displayed users , stick it. consistently. see below.

the problem world-spanning applications may have server in bangalore users in rome. have 2 choices - either timestamp every operation time zone of actual server "resides" , allow users adjust mentally discrepancies, or still timestamp specific time zone (you can of course of study utilize utc instead of local time, , applies other method, too) , automagically translate user local timezone while displaying.

so may have "record created @ utc 12-may-2014 00:34" stored in db , show me "record created @ 12-may-2014 01:34 met" because using application italy.

(this prove easier users if application allows them create entries time input - illustration booking room meeting - cost more in terms of development, , may become bit complex manage when same record can updated different time zones).

these basics, really... have read i18n, of course, , decide if want error messages , ui labels multilingual. i18n cares (i.e. how manage input , output in different languages) gives guidelines more esoteric stuff culturally-appropriated icons suggest bit of research on it.

performance - Delphi 7, Windows NT Service, Console App -

performance - Delphi 7, Windows NT Service, Console App -

i have delphi 7 32bit application. windows 7 64bit.

everything runs fine. have been investigation performance issues i've noticed.

a brief overview of application -->

has command-line / console app executable, written in delphi. creates multi-threaded set of connections , database work. nt service, written in delphi (which calls command-line application), based on schedules of jobs finds. done via phone call our dll, finds , executes createprocess commandline application, , waitforsingleobject finish. effectively, service responsible finding when work needs done, , callin executable/console app it.

here's problem, cannot seem figure out.

if run command-line application, 4x faster result if nt service phone call via createprocess. identical code. 1 dos prompt issuance of exe, other nt service, loads dll, calls createprocess same executable.

i going bananas. cannot see reason this.

i can reproduce on scheme configuration far.

what i've noticed far (not scientific, relevant imo).

if monitor cpu cores cpu time , kernel time, console app has fraction of kernel time during life-time of execution. when scheduler service runs this, kernel time represents 50-70%% or more of whatever cpu % utilize getting.

some actual results (everything else irrelevant believe) - console app, run through commandline: 26 seconds - console app, run through service via createprocess: 113 seconds

what gives?

i've looked perhaps fastmm isnt beingness shared properly. believe is. remoed it. same anomalies. i've looked perhaps fastcode, fastmove stuff isnt working under service (since @ startup, trying dynamically hook/replace core rtl functions. removed them equation, same anomalies. i've looked removing our patched rtl (system.dcu/sysinit.dcu) files. no joy.

all no avail.

so, questions (and solicitation possible reasons), ...

does nt service preclude ability perform automation/hook replacement features? delphi services create cause this? there sort of inherent overhead -- (and huge amount) services? there alternatives using fastmm, fastcode, fastmove others have used because of of nature?

thanks in advance guidances/helpers here.

here's snippet of code used launch app nt service.

fillchar(si, sizeof(si), 0); si.dwflags := sw_hide; fillchar(pi, sizeof(pi), 0); scommandline := format('"%s" "%d"', [extractfilepath(paramstr(0)) + 'myapp.exe', ajobid]); if createprocess(pchar(sfilename), pchar(scommandline), nil, nil, false, 0, nil, nil, si, pi) begin waitforsingleobject(pi.hprocess, infinite); getexitcodeprocess(pi.hprocess, exitcode); result := (exitcode = 0); end else begin addeventlogmessage(syserrormessage(getlasterror)); end;

it turns out issue related utilize of connections, , sharing connection.

once took approach of destroying connection on scheduler before launching createprocess, kernel usage inline seeing when running straight console.

very surprising, given connection not shared commandline doing.

future reference: sure eliminate variables before saying 2 approaches identical. in this, not. scheduler had connection, console app did not. , difference.

node.js - Node Pass Hidden Data To Other Route -

node.js - Node Pass Hidden Data To Other Route -

i have route in express(item/update/), , after happens want send them /, want create / show alert 'success' or 'failure'. don't want utilize query string or hash because want hidden user. don't want render / @ items/update seems bad idea. also, have tried javascript history api, seems hack history api else.

please allow me know if there more info need.

you can couple of ways,

1.you can redirect "/" url query string. since don't add together info in query string, alternate alternative session.

for example,

function itempupdatehandler(request,response){ //do stuff request.session.displaymsg = "update done successfully"; response.setheader("location: http://yourdomain.com/"); response.end(); } function homepagehandler(request,response){ //display message here read session. if(request.session.displaymsg){ console.log(request.session.displaymsg); delete request.session.displaymsg; } //do regular suff here. }

2.you have take care more in next method, here aren't going redirect need modify handler function follows,

function itempupdatehandler(request,response){ //do stuff //response.setheader("location: http://yourdomain.com/"); //no need here homepagehandler(request,response, {display:true, msg: "update done successfully"}); } function homepagehandler(request,response, moreargs){ //display message here read session. if(moreargs.display){ console.log(moreargs.msg); } //do regular suff here. }

note: assumed using express

i cant seem create these errors mean. inadvance

you can't separate definition , implementation templated classes. have set functions in header file well.

c++
