edit: seems issue on end, @ least wasn't able replicate outside of mac os setup chrome / safari. i'm using google maps on this site , , seems lighten text (not sure other elements) below it. navigation above doesn't seem affected. you can see best when comparing 'h2' "besuchen sie uns" 'h2' on other pages . in fact, can see when load page. brief second, before google maps starts loading, text has original styling. now, can't explain , haven't found @ all. granted, don't have experience google maps, doing wrong? both headers have computed font-weight:300 , color:#414141 , same computed font-family on chrome, , there don't appear google maps introduced style rules match them. the header on map integration page seem overlap map, there doesn't seem z-index issue.

i have file, "items.txt" containing list of 100,000 items need remove file "text.txt" , replace "111111111". i wrote script works intend: #!/bin/bash a=0 b=`wc -l < ./items.txt` while read -r line a=`expr $a + 1` sed -i "s/$line/111111111/g" text.txt echo "removed ("$a"/"$b")." done < ./items.txt this script looks @ eat line in "items.txt", uses sed remove each line "text.txt". this script slow though. estimate, take more 1 week remove of items file on computer. there more efficient way replace of items quickly? bash 4.1.5 use sed build sed script replace items: sed 's/^/s=/;s/$/=111111111=g/' items.txt | sed -f- text.txt update: following perl script seems faster: #!/usr/bin/perl use warnings; use strict; open $items, '<', 'items.txt'; @items = <$items>; chomp @items; $regex = join '|', @items; $regex =

should have bean every form, datatable etc in jsf? for example, have form registration, has 2 fields , button are: nickname, password, submit should submitting form go registirationformbean or somewhere in userbean or userservicebean? what best practice? thank you. to decide whether or not should create @managedbean exclusively component of page (e.g. form, datatable), believe should think modularity of design. the 1st question should ask is: will component re-used in many pages? . example, on sensitive pages such changepassword or deleteaccount , usually, ask user enter current password validate identity before performing logic. in case, should have exclusive bean validating password component can re-use component again , again without having re-code validating function every time. secondly, use @managedbean place hold related functions work toward same goal . grouping of functions can pretty subjective. example, can have page called createproduct.xhtml

for project, need able store random byte strings in file , read byte string again later. example, want store randombytestring following code: >>> os import urandom >>> randombytestring=urandom(8) >>> randombytestring b'zoz\x84\xfb\xcem~' what proper way this? edit: forgot mention want store 'normal' string alongside byte strings. code like: >>> fh = open("e:\\test","wb") >>> fh.write(randombytestring) 8 >>> fh.close() operate file binary mode. also, in better manner if file operations near 1 place (thanks @blender): >>> open("e:\\test","wb") fh: fh.write(randombytestring) update: if want strong normal strings, encode , write like: >>> "test".encode() b'test' >>> fh.write("test".encode()) here fh means same file handle opened previously.

i have 2 questions regarding project. appreciate if clarifications on that. i have decomposed address individual entities breaking down smallest unit. bur addresses repeated in few tables. address fields there in client table employee table. should separate address separate table linking field for example create address table following attributes : entity_id ( employee id(home address) or client id(office address) ) unit building street locality city state country zipcode remove address fields employee table , client table we can obtain address getting employee id , referring address table address which approach better ? having address fields in tables or separate shown above. thoughts on design in better ? ya separating address better because people can have multiple addresses increasing data redundancy. you can design database problem in 2 ways according me. a. using 1 table table name --- address column names serial no.

i'm trying draw line representing complex number on circle (base image: http://i.imgur.com/mngenrp.png ) starting centre of circle , ending on point on circle. here come problems: i have tried many formulas find $x2 , $y2 ended randomly positioned lines. what's right formula calculate ending coordinates? edit: cleong solved positioning problem line still long, goes out of circle , out of image. of formulas use are: $x2=$half+($radius*(cos(deg2rad($theta)))); $y2=$half-($radius*(sin(deg2rad($theta)))); where $half centre of circle (in pixels), $radius radius of circle in pixels , $theta angle in radians. in advance.

what kind of problem may occur code? think exception occurs, code can throw exception caller. not generate trouble. how can improve it? public static void cat(file named) { randomaccessfile input = null; string line = null; try { input = new randomaccessfile(named, “r”); while ((line = input.readline()) != null { system.out.println(line); } return; } { if (input != null) { input.close(); } } } what kind of problem may occur code? public randomaccessfile throws filenotfoundexception . public final string readline() throws ioexception . public void close() throws ioexception . since public class filenotfoundexception extends ioexception you can change method to: public static void cat(file named) throws ioexception and don't need try-catch blocks. and caller should catch exception thrown method. but why don't want catch exceptions?

i'm using nservicebus send orders (one order per command) back-end systems. each order has customer (parent). back-end system publishes "order accepted" event after order saved successfully. there multiple subscribers event 1 of them file generator component generates xml file consumed third party. file generated per customer. since published event @ order level every time "order accepted" event published file component creates entire file customer. is there way within nservicebus group events @ subscriber can reduce number of times file generator runs if there multiple orders same customer? one idea had put subscriber sleep fixed time , when wakes can group messages in queue customer , generate file once per customer. sound idea? thanks in advance. the best way use saga behavior of debouncer. the saga subscribe event, , every time observed, request new timeout period of time willing wait, let's 5 minutes. if timeout message arrives ,

i have view in data form , use run python script within view. python script gives output , needs prompt user proceed further , perform other functionality. how can in single view ?? my views.py class deploywizard(sessionwizardview): template = "deploy_form.html" def done(self, form_list, **kwargs) : form_data = process_form_data(form_list) #process data form form #call script of the form data argument # display output user , ask user proceed (something "yes", "no") , proceed further # again call python script other arguments return rendor_to_response("done.html", {'form_data' : form_data}) i think should use either django's form wizard or form preview depending on precise use case. the former if need classic multi-step wizard, latter if need user confirm input.

i using jface treeviewer while. has bunch of branches of varying lengths, @ end of day, entire tree stretched size of longest string. great. recently, decided treeitems labels should have style them fonts , highlights. the trouble, new fonts bit larger , stretch size of overall string. seems tree or treeviewer doesn't recognize expansion , still judges size of label amount of small characters in it. result treeviewer horizontal scrollbar, highly inconvenient because users have scroll across each tree, rather being glance @ data. does know how tree fit length of longest string, , take account added length of styling, etc? thanks! while not complete answer, hope jogs someone's memory has more advanced knowledge on this: when set font viewercell object font wide, entire row resizes. seems tree measures width checking length of text , font, disregards style ranges .
