i trying figure out how find duplicate atom in possibly nested lists. have been trying figure out day. if please give me logic, great because want learn. basically (finddup '(a b b)) return t (finddup '(a c ((d (f a)) s))) return t the easiest , efficient way following (pseudocode): create data structure (such common lisp's hash table) remembering atoms seen create recursive sub-function actual traversing - walking nested lists , adding new atoms data structure, , if 1 there, returning true

fixed issues code. ok, think need clarify question. new a.example(); outputs "a" what should inside example method output "???"? possible? public class letter { public virtual void asastring() { console.writeline("???"); } public void example() { this.asastring(); } } public class : letter { public override void asastring() { console.writeline("a"); } public void example2() { base.asastring(); } } new a().example2(); new a().example(); that's easy: public void example() { console.writeline("???"); } from answer should realise asked wasn't thought asked for... if mean want call virtual method if wasn't virtual, not possible. if cast reference base class, still uses actual type of object determine method call.

is there way print numbers 1 100 without using loops or conditions "if"? can using recursion again has if condition. there way without using "if" well? no repetitive print statements, or single print statement containing numbers 1 100. a solution in java preferable. pseudo code. uses array force exception after 100 elements caught , nothing. function r(array a, int index){ a[index] = a[index-1]+1 print a[index] r(a, index+1) } try{ array a; a.resize(101) r(a, 1) }catch(outofboundsexception){ } edit java code: public void printto100(){ int[] array = new int[101]; try{ printtoarraylimit(array, 1); }catch(arrayindexoutofboundsexception e){ } } public void printtoarraylimit(int[] array, int index){ array[index] = array[index-1]+1; system.out.println(array[index]); printtoarraylimit(array, index+1); }

for reason i've been trying figure out, links on page clickable, aren't going anywhere. markup looks fine, , can't figure out if there's issue css rendering them useless. added in z-index tag, but, had no effect. note: css below taken firebug, not actual stylesheet... markup: <li class=""> <span id="thmr_93" class="thmr_call"> <a href="/edit/1">edit</a> </span> </li> css: .tabs ul.primary, .tabs ul.primary li { float:left; line-height:normal; list-style-image:none; list-style-position:outside; list-style-type:none; margin:0; padding:0; text-align:left; } .tabs ul.primary li { color:#008080; text-decoration:none; height:30px; line-height:30px; margin:10px; width:100%; z-index:100; list-style-image:none; list-style-position:outside; list-style-type:none; text-align:left; } i going guess, bas...

in php script doing lot of different curl requests (a hundred) different url. is reusing same curl handle curl_init improve performance or negligible compare response time of curl requests? i asking because in current architecture not easy keep same curl handle. thanks, benjamin it depends on if urls on same servers or not. if are, concurrent requests same server reuse connection. see curlopt_forbid_reuse. if urls on same server need sort urls default connection cache limited ten or twenty connections. if on different servers there no speed advantage on using same handle. with curl_multi_exec can connect different servers @ same time (parallel). need queuing not use thousands of simultaneous connections.

can recommend website or give me brief of how backpropagation implemented in nn? understand basic concept, i'm unsure of how go writing code. many of sources i've found show equations without giving explanation of why they're doing it, , variable names make difficult find out. example: void bpnn_output_error(delta, target, output, nj, err) double *delta, *target, *output, *err; int nj; { int j; double o, t, errsum; errsum = 0.0; (j = 1; j <= nj; j++) { o = output[j]; t = target[j]; delta[j] = o * (1.0 - o) * (t - o); errsum += abs(delta[j]); } *err = errsum; } in example, can explain purpose of delta[j] = o * (1.0 - o) * (t - o); thanks. the purpose of delta[j] = o * (1.0 - o) * (t - o); is find error of output node in backpropagation network. o represents output of node, t expected value of output node. the term, (o * (1.0 - o), derivative of common transfer function used, sigmoid function.

i have procedure (slightly more complex) version of below: create proc sp_find_id ( @match1 varchar(10), @match2 varchar(10) ) declare @id int select @id = id table1 match1 = @match1 , coalesce(match2,@match2,'') = coalesce(@match2,match2,'') select @id id essentially match1 mandatory match, match2 both optional on input procedure, , on table being searched. 2nd match succeeds input and/or table match2 values null, or they're both same (not null) value. my question is: there more efficient (or more readable) way of doing this? i've used method few times, , feel sullied each time (subjective dirtiness admittedly). is there more efficient (or more readable) way of doing this? the example provided, using coalesce/etc non-sargable . need separate things needs present in query run: declare @id int if @match2 not null begin select @id = t.id table1 t t.match1 = @match1 , (t.match2 = @match2 or t.match2 null...

i have linq query simple like: var k = people.select(x=>new{x.id, x.name}); i want function or linq lambda, or output names in sentence format using commas , "ands". {1, john} {2, mark} {3, george} to "1:john, 2:mark , 3:george" i'm fine hardcoding id + ":" + name part, tostring() depending on type of linq query result. i'm wondering if there neat way linq or string.format(). public string toprettycommas<t>( list<t> source, func<t, string> stringselector ) { int count = source.count; func<int, string> prefixselector = x => x == 0 ?

i'm halfway through figuring out solution question, have feeling won't efficient. i've got 2 dimensional cell structure of variable length arrays constructed in non-functional way in matlab convert clojure. here example of i'm trying do: pre = cell(n,1); aux = cell(n,1); i=1:ne j=1:d k=1:length(delays{i,j}) pre{post(i, delays{i, j}(k))}(end+1) = n*(delays{i, j}(k)-1)+i; aux{post(i, delays{i, j}(k))}(end+1) = n*(d-1-j)+i; % takes account delay end; end; end; my current plan implementation use 3 loops first initialized vector of n vectors of empty vector. each subloop initialized previous loop. define separate function takes overall vector , subindices , value , returns vector updated subvector. there's got smarter way of doing using 3 loop/recurs. possibly reduce function simplifies syntax using accumulator. i'm not 100% sure understand code doing (i don't know matlab) might 1 approach building multi-dimen...

what trying is, seemingly, simple: send pox via request body, have wcf service process it, , return 201 status code. in servicecontract have defined following method: [webinvoke(method = "put", uritemplate = "/content/add", bodystyle = webmessagebodystyle.bare, responseformat = webmessageformat.xml, requestformat=webmessageformat.xml)] [operationcontract] stream addcontent(stream input); the verb here doesn't matter; replace 'put' 'post' , wind same result. implementation of above method follows: public stream addcontent(stream input) { weboperationcontext.current.outgoingresponse.statuscode = system.net.httpstatuscode.created; } since method of little consequence have omitted of procedural code. test functionality fired fiddler , issued following request: user-agent: fiddler host: myhost.com content-length: 771 content-type: text/xml && application/xml; charset: utf8 <xmldatagoeshere...

i've got set of rows in database, , i'd provide interface spin through them this: def findall: iterable[myobject] where don't require having instances in memory @ once. in c# can create generators using yield, compiler takes care of converting code loops through recordset iterator (sort of inverting it). my current code looks this: def findall: list[myobject] = { val rs = getrs val values = new listbuffer[myobject] while ( rs.next() ) values += new valuefromresultset(rs) values.tolist } is there way convert not store entire set in memory? perhaps use comprehension? try extending iterator instead. haven't tested it, this: def findall: iterator[myobject] = new iterator[myobject] { val rs = getrs override def hasnext = rs.hasnext override def next = new valuefromresultset(rs.next) } this should store rs when it's called, , otherwise light wrapper calls rs. if want save values traverse, check out stream.

in eclipse ide how can access java class .jsp accessing servlet jsp file ? in other word, should replace question marks "????????" <form name="myform" action="???????????????" method="post"> </form> when run engine.java file "mypackage" package tomcat application servers shows address in address bar. http://localhost:8080/rouyesh/servlet/mypackage.engine anybody can please? you'll need use whatever path relative current url is, or absolute path, files. might prudent @ point investigate web framework, however, before destroy product insanity :p.

i'm sure quite simple can't seem work. i'm trying set selection of radcombobox using ondatabound function. protected void reto_databound(object sender, radcomboboxitemeventargs e) { if (e == null) throw new argumentnullexception("e"); var combo = sender radcombobox; if (combo.finditembytext("jack johnson") != null) combo.finditembytext("jack johnson").selected = true; } i think i'm calling combobox incorrectly. thanks help. i can't solve here finditembytext "smelly" :), don't item string value, 1 char difference... try check item value not text , see happens. cheers

consider following "code" define stmt1 = 'insert t(a, b) values(1, 1); define stmt2 = 'select * t'; mssqlcommand.execute( stmt1;stmt2 ); mssqlcommand.execute( stmt2 ); investigating cached query-plans using: select [cp].[refcounts] , [cp].[usecounts] , [cp].[objtype] , [st].[dbid] , [st].[objectid] , [st].[text] , [qp].[query_plan] sys.dm_exec_cached_plans cp cross apply sys.dm_exec_sql_text ( cp.plan_handle ) st cross apply sys.dm_exec_query_plan ( cp.plan_handle ) qp ; my impression first "execute" generates composite execution plan instead of 2 singular execution plans, thereby disabling second "execute" reusing execution plan generated in first execute. am right? yes, you're right. reuse the second part of execution plan need split first statement 2 separate execution plans. can either executing them separate mssqlcommand.execute calls or using 2 calls sp_executesql in 1 query (this adds 1 level of indi...

i have solution checked tfs. looking in source control explorer have .cs file in solution. looking in solution explorer it's missing. when project built takes file consideration , it's code included in build. a collegue of mine has pulled code tfs , built , appears expected. any ideas? had same problem. did was, keeping solution/projects open. went windows explorer, deleted files of project not showing files. tfs, got files project. prompted reload project, , voila - files showed up. not sure why happened though.
