i'm reading architectural patterns chapter of poeaa, , fowler says "as domain logic gets more complicated , begin moving toward rich domain model (116), simple approach of active record (160) starts break down. one-to-one match of domain classes tables starts fail factor domain logic smaller classes. relational databases don't handle inheritance, becomes difficult use strategies [gang of four] , other neat oo patterns. domain logic gets feisty, want able test without having talk database time." i didn't understand this. "one 1 match of domain classes tables", mean classes there no associations or single table inheritance hierarchy? and why factoring domain logic smaller classes cause pattern fail? what he's trying more complex domain models more "data table". these more complex models fowler talking models data different tables, views or maybe other sources. the active record pattern not suitable purpose, , datamapper p...

i require clarification on 1 technical implementation check feasible or not. i have 1 vps server has java environment , have 1 more dedicated server doesnot have java environment have built php based web application, in vps environment planning implement xml based application using observer pattern java , dom parsers , make application available @ example 123.124.125.65/xml_works/sample,xml file now doubt that: 1)is possbile access application in dedicated server java environment not there. 2)if yes, possible access java + xml application in iframe in php based web portal. 1) no jvm = no java running on machine 2) common solution saw (and using) externalize java functionality want web service or servlet , package .war use web container such tomcat load war , use connector connect calls tomcat php server. so configuration use is, java war, tomcat web container, apache php server , mod_jk connector communication between servers. note mod_jk connector support...

i'm having play around monotouch for first time . in hello world tutorial noobs-like-me, say's following :- launch interface builder double-clicking on mainwindow.xib file. once interface builder starts up, should see surface (your window) , library contains various components. library should following screenshot. if not there, select library tools menu when try that, nothing happens. no new 'window' shows. if goto tools menu, there no option library. the solution type made c# iphone window-based project . can me please? interface builder part of ios sdk made available developers apple; not part of monotouch or monodevelop ide. if nothing happens when try open .xib file, ib may not installed on mac. to obtain it, go the ios dev center , download xcode 3.2.6 , ios sdk. make sure download xcode 3 , not xcode 4, ib separate application in version 3. quoting this answer of mine find xcode 3 download link: ... under xcode 4 + ios s...

i have list of lists, snippet of below: x_attrib = [] self.x_attrib.append(["is_virtual", false, 'virtual', 'flag']) self.x_attrib.append(["x_pos", none, 'pos/x', 'attrib']) self.x_attrib.append(["y_pos", none, 'pos/y', 'attrib']) i want make functional returns index of item @ first position (i.e. want pass "x_pos" function, , have return 1 ). how can this? if understand correctly, need this: def find_it(key): index, sublist in enumerate(lists): if sublist[0] == key: return index having said code looks solving more general problem incorrectly. i.e. list bad idea. without better idea of doing cannot certain.

consider program: public class test { public static void main(string [] args){ runnable r = new runnable() { public void run() { system.out.print("foo"); } }; thread t = new thread(r) { public void run() { system.out.print("bar"); } }; t.start(); } } on running output is bar i know why so. my understanding: we instantiate anonymous inner class implements runnable overriding run method. , assign r. next pass runnable thread class constructor. create new anonymous inner class extends thread overriding run. so have 2 run methods , 2nd take preference on 1st. i'm confused please correct me if i'm wrong. also such crazy things used in real world java programming? (my prof says yes , thats keeps going :d). though pass runnable instance constructor, you're overriding run method in such way, doesn't ...

hi cannot see explanation of implementation of collapse_key. think understand not how it! android cloud device messaging framework i have c2dm framework set , sending 4 types of messages many phones. string messages basic looks kind of this: type:name:uuid type:name:uuid:number type:uuid:id if phone off many of can piled waiting phone on-line. far can tell system works collapse_key me here? addencodedparameter(sb, "collapse_key", "no_ide_what_to_put_here"); you mentioned retrying same message 3 times , using same key value. doesn't have same message. if you've got message indicates current price of stock, instance, , care latest price, send different messages same key. when device comes online, gets latest price quote message. this may have been saying already, wanted make clear it's not "retrying sending same message".

i'm using white automate bdd testing of our c# wpf ui. my first couple of tests working on development machine (running windows 7). however, when try , run same code on build server (virtual machine running windows server 2003 r2) doesn't work correctly. in both cases tests run command line , tests using cuke4nuke framework. in case of server accessing server via remote desktop connection. the code looks like: var application = application.launch("whiteapp.exe"); var initializeoption = initializeoption.nocache; var windowcriteria = searchcriteria.bytext("whiteapp"); var window = application.getwindow(criteria, initializeoption); var criteria = searchcriteria.byautomationid("rightbutton"); var button = (button) window.get(criteria); button.click(); the problem buttons click event not fired when run on server. button can clicked (using mouse) if ui left open after white has finished executing. 1 interesting point after click method r...

i have use case need diagnostics , performance data of azure web-role monitored remotely done without storage account. adding stuart's answer: diagnostic monitor set collect counters, logs, , diagnostics locally , aggregate them well-known azure storage tables, requires storage account. if wrote background process periodically poll local counters, push them instances pretty anywhere want: sql azure, sql server (on premise), web service, email, etc. however, stuart says, feels reinventing wheel. the diagnostic monitor aggregates counters across of instances, letting aggregate counter values across of web roles, instance, or letting drill down on specific instance easily. not sure why you'd want avoid storage account diagnostics. @ $0.15/gb, it's going have low cost overhead, if you're storing diagnostic data. plus, 3rd party monitoring tools (such azurewatch ) need pull counters storage account.

i've table, there column called "locations" in type of varchar(max). carries string of comma-separated code, e.g. '1, 3, 4' . on other hand, i've table map these code locations, e.g. 1 -- british 2 -- new zealand 3 -- hong kong 4 -- taiwan my problem is, i'm making view map , replace content of column "locations" corresponding comma-separated text, e.g. '1, 3, 4' 'british, hong kong, taiwan' this urgent company project, please kindly advise. thank you! regards, william there might simpler solutions here 1 way. table structure create table locations(locationid int, location varchar(50)) create table othertable(id int, locations varchar(max)) test data insert locations values(1, 'location <1>') insert locations values(2, 'location <2>') insert locations values(3, 'location <3>') insert locations values(4, 'location <4>') insert locations values(5...

it has come attention can unit-test abstract class instantiating mock object. thereby mock abstract properties , methods, while being able test implemented ones. however, accustomed distinguish between class to test , injected dependencies to mock/stub . so, in stage of new enlightenment wonder if there pitfalls way of testing?? thoughts on this? regards, morten an abstract class, of value, should have concrete subclasses can instantiated. unit test those, , via them implicitly base class. if has no concrete subclasses, can't think of reason why should exist (as abstract class, is). in general, prefer use mocking set environment of class tested, not instantiate class itself. distinction - me - keeps test cases clearer, , ensures test real functionality of class. of course, can think of cases (with legacy code) when main issue able write unit tests somehow, anyhow, enable refactoring (as discussed in working legacy code ). temporary solution in such cases, ...

after re-write of subtree history repository script of mine, compared git filter-branch ... on same subtree. see initial commits have different sha1 although expected them identical (consequence of commits both histories have different sha1). doing git show --format=raw <commit-sha1> on both commits gives same output (except first line, commit <commit-sha1> , introducing result). object files different, binaries, can't figure out root cause. assuming git versions consistent each other, explain have 2 different sha1? thank you git's inputs commit hash include metadata such sha1 of tree, sha1 of parent, commiter's name, email , commit date, , author's name, email , commit date. when rewrote history, commiter commit date , tree (since did filter-branch ) have changed, hence difference in commit's sha1. for more information format of commit, can use git cat-file commit <sha> , or git objects section of git book .

say have meta data custom file format python app reads. csv variables can change file manipulated: var1,data1 var2,data2 var3,data3 so if user can manipulate meta data, have worry crafting malformed meta data file allow arbitrary code execution? thing can imagine if you made poor choice make var1 shell command execute os.sys(data1) in own code somewhere. also, if c have worry buffers being blown, don't think have worry python. if reading in data string possible somehow escape string "\n os.sys('rm -r /') , sql example totally wont work, there similar possible? if doing there (plain text, reading , parsing simple format), safe. indicate, python safe more mundane memory corruption errors c developers can create if not careful. sql injection scenario note not concern when reading in files in python. however , if concerned security, seems (interjection: you! programmer should lazy and paranoid), here things consider: validate input . make sure each ...
