i guess else opposite need hide "directory" structure of asp.net website. for reason thinking of use robots.txt follows... user-agent: * disallow: / use url rewriting, make ghost paths disable directory browsing. (directory listing denied...) use .ashx serve images. other ways may suggest. in other words not "downloader-structrure reader", strip site. as see sekurity tag missing :) p.s. not care seo a site downloader wget -r work anyway. follows links , doesn't care directories (except fact can limit depth). if want exclude legit crawlers google, using robots.txt fine. wget , rogue crawlers don't care though. the solution either requriring login (but still doesn't protect against people who'd use wget download whole site; they'll provide login information/session id) or cluttering content annoying captchas (pisses of legit users quickly) or making whole site use javascript/ajax display/load content. makes user e...

i know may sound blasphemy lisp aficionados (and other lovers of dynamic languages), how difficult enhance clojure compiler support static (compile-time) type checking? setting aside arguments , against static , dynamic typing, possible (not "is advisable")? i thinking adding new reader macro force compile-time type (an enhanced version of #^ macro) , adding type information symbol table allow compiler flag places variables misused. example, in following code, expect compile-time error (#* "compile-time" type macro): (defn get-length [#*string s] (.length s)) (defn test-get-length [] (get-length 2.0)) the #^ macro reused global variable ( *compile-time-type-checking* ) force compiler checks. any thoughts on feasibility? it's possible. compiler static type checking around primitive argument types in 1.3 development branch.

i have view needs return type decimal columns stored float. i can cast each column decimal follows: , cast(field1 decimal) field1 the problem approach, decimal defaults 18,0, automatically rounds float columns 0. keep precision of 12 decimal places. however, if this: , cast(field1 decimal(12,12)) field1 i runtime error: "arithmetic overflow error converting float data type numeric" the float column defined length: 8 precision: 53 in table. can not modify table. what's proper way cast decimal w/out losing decimal precision? 12, 12 means no digits before decimal separator: 12 digits in total, 12 of them being after period. use more appropriate range, say: declare @var float = 100 select cast(@var decimal(20,12)) which gives 8 digits before separator, or adjust needed.

i have issue letting secret api key on world on potentially thousands of mobile devices. compromised , used malicious purposes hacker. so options me? guess private server has secret api key , web service encapsulates method calls. instead of mobile device having secret key , like: list<friends> = service.getfriends(secretkey); if secret api key compromised , used spamming/abuse purposes, must shut down use users, leaving application dead in sea. so idea can use mobile device unique device id , do: list<friends> = myservice.getfriends(deviceid); of course, malicious hacker call web service fake deviceid, @ least have control blacklist deviceid's. introduces potential bandwidth isssue, of less concern. a true pki out of question, since targetted device doesn't handle http client certificates in current version. any other ideas? you don't want publish api key facebook or twitter, obfuscated within client. your instincts correct proxy th...

bytecode enhancement seems interesting java technique, has feel of bit of "black magic" it. there disadvantages using (other fact functionality added classes not apparent source code)? does cause problems security, serialization, etc.? are there disadvantages using (other fact functionality added classes not apparent source code)? one thing bugs created bytecode manipulation more difficult diagnose. examination of source code, , source level debugging harder. does cause problems security, the verifier should (in theory) prevent modified bytecode breaking core type system , corrupting jvm.

i've noticed lot of time when search on google, google automatically uses search function of relevant websites , return result of website search if url. how let google , other search engines know search box on own website , open search has it? do maybe mean site search function via google chrome omnibar? to there need have a form method type get input type text element submit button on root page of domain if users go directly root page , search there, google learns of form , adds search engines accessible via omnibar (the google chrome address bar). did mean this?

i came across example of race condition: def inc(n) n + 1 end sum = 0 threads = (1..10).map thread.new 10_000.times sum = inc(sum) end end end threads.each(&:join) p sum threads run in pararell , there's chance while 1 thread reads sum's value, 1 completes incrementing it, former finish own incrementing old value, , result sum won't change. but wondering, why when replace line 'sum = inc(sum)' 'sum += 1', output appears correct. why that? is because overhead of calling method huge compared doing variable assignment , threads 'get out of sync' causing output incorrect? i assume, straight sum += 1 still able observe race condition, if had been doing longer summing loop, etc.? is because overhead of calling method huge compared doing variable assignment , threads 'get out of sync' causing output incorrect? yes. verify it, increase counter , run several tests. increased 100_000.times , ...

i learning core java , have 1 question, "which first method called when program executed?" in addition aioobes answer a usual way start simple java program execute java this: java com.example.myclass com.example.myclass (or qualified class name) needs have main method signature: public static void main(string[] args) (you're allowed change name of parameter, arguments instead of args ). virtual machine try load named class , try invoke static method "start java program".

sorry if bit of vague question, im struggling find single solid example on how unit testing (isolated testing) android... here example of i'm wanting achieve: // class class calculator { public int add(int a, int b) { return a+b; } } // simple test import org.junit.assert; import org.junit.test; class calculatortests { @test public void should_add_numbers_correctly() { calculator calculator = new calculator(); int expectedresult = 5 + 5; int actualresult = calculator.add(5,5); assert.assertequal(actualresult, expectedresult); } } so 1 project contains models , logic, project contains tests said library. there no front end or ui, want bare minimum able test methods work in isolation. as long "library" doesn't contain references resources in android sdk, there isn't more regular unit testing. in eclipse workspace, have main project myandroidlibproject , create new java project (e.g. myandr...

greetings, it's provocative question, aiming open debate how abstraction inversion seen among developer community. i'm curious know think. first, here quote abstraction inversion exemples given wikipedia: http://en.wikipedia.org/wiki/abstraction_inversion creating object represent function cumbersome in object-oriented languages such java , c++, in functions not first-class objects. in c++ possible make object 'callable' overloading () operator, still necessary implement new class, such functors in stl. for me functions first-class citizen in scala, when use scala generate java bytecode, scala create specific class 'on top' of java make functional programming possible... can see abstraction inversion ? same can apply clojure or functionnal language jvm... or apache collections, exemple this: http://commons.apache.org/collections/apidocs/org/apache/commons/collections/closure.html btw, i'm not convinced wikipedia article objectivity. e...

i have mysql table has, among other attributes, timestamp, type , user_id. of them searchable and/or sortable. better create index each one, or create single compound index three, or both? pablo's answer correct, maybe you'll fail realize compound index might justified. you can have multiple indexes , having idx1(tstamp, user_id) not exclude having indx2(tstamp, type) or idx1reverse(user_id, tstamp) , on... compound indexes useful when cover of conditions in query, index propose useful for select * my_table tstamp = @ts1 , user_id = @uid , type = @type if want improve performance of such queries can consider adding composite index. the downside of indexes slows down update operations. however, general applications many more selects updates (both in terms transactions i.e. number of statements , in terms of of records affected/retrieved) , @ same time more tolerant of slower updates (users judge speed of system not time necessary update record, time n...

as question asks really. the ef modeller tool allows map insert/update/delete functions sproc, there benefit overriding them? if requires custom validation, yes, if i'm happy how now, worth creating sproc's them all? i can't remember how view sql it's executing them find out exact query, should imagine it'd pretty similar standard insert/update/delete query. i can think of few cases useful: you're working legacy database doesn't quite map ef model precisely. you need queries executed on insert/update/delete, don't have rights triggers on database. soft deletes in database want abstract away from. regular delete perform soft delete. not quite sure how viable these options are, more of nhibernate guy. these theoretical options. as viewing executed queries, there's few possibilities that. attach profiler sql server instance , @ raw queries executed. there's entity framework profiler (by ayende/oren eini) isn't free, ...

i have 2 options: public class syntaxexception extends runtimeexception { private string msg; public syntaxexception(string m) { this.msg = m; } public string getmessage() { return "invalid syntax: " + this.msg; } } and public class syntaxexception extends runtimeexception { public syntaxexception(string m) { super("invalid syntax: " + m); } } which 1 preferred, if have think code maintainability , extendability? use second one. argument constructor of both runtimeexception , inherited class error message, there's no reason duplicate functionality given runtimeexception in code.
