i'm taking algorithms , data structures course , 1 the slides informs "consistently balanced trees hard implement" , quotes following phrase: “the difficulty of implementing balanced trees restricts use; balanced trees implemented except part of programming assignment in data structures class.” -- w. pugh is true these data structures implemented in real world? using , applying balanced trees doesn't seem hard - missing? i know examples of difficulties can experienced in real applications make balanced trees hard implement. balanced trees hard right if don't have lot of experience in designing data structures, or can't details in text book. people never implement trees scratch. despite that, balanced trees popular, because programming environments can find library implements them. languages have them in standard library.

example write down myfunc('asdas') it's console.log me 'asdas' then after write down myfunc('as')('ds')('ko')....('other') function must console.log me "as ds ko .... other" i tried realize have many problems it. function me (str){ //var temp = str; return function mes(val) { val += ' '+ str; console.log(val); //return mes; } } how correctly realize function? well, bit funny, works: concat = function(x, val) { val = (val || "") + x; var p = function(y) { return concat(y, val) }; p.tostring = function() { return val }; return p } x = concat('a')('b')('c')('d'); document.write(x)

i wonder if there way show crm 2011 forms (like information form of contact entity) on aspx page? i want build customer portal (asp.net) shows fields configured in crm itself. any suggestions? cheers you have few options: put iframe aspx page , point crm form url. url has following format: http://myhost.com/orgname/main.aspx?etn={entityname}&pagetype=entityrecord&id={entityguid} use crm database views (or crm webservice ) directly application. configure datasource crm database downside of first solution users asked credentials (you want introduce sso ) , if crm running on different domain bit difficult ensure javascript communication between page , iframe. however, not impossible - http://easyxdm.net/wp/ . advantage it's pretty easy build. the second solution more work on other hand have under control.

forgive me here - despite best efforts rather non-precise way of asking precise question! i pointed towards following website on generating server side key/cert (pem file) twisted python tls server: https://twistedmatrix.com/trac/browser/trunk/twisted/test/server.pem as can see, code here generates pem file contains python source (subsequently removed!) , certificate, , private key. from here, used following generate public key (since pyopenssl apparently has no way of exporting it) openssl x509 -pubkey -noout -in server.pem > public.key i used server.pem file generated above in "starttls_server.py" sample found here: https://twistedmatrix.com/documents/14.0.0/core/howto/ssl.html however, corresponding starttls_client.py example seems want use same "server.pem" file. surely wrong? (limited!) understand of tls client given copy of public key, , used handshaking. nontheless tried it, , wasn't overly surprised when didn't work: failure: tw...
