simplified background: my app runs lot of tasks. of them cpu intensive. 1 task (which single thread running in loop, listening packets network), "realtime" task. make more interesting, thread native code called using pinvoke . the problem: when lot of traffic showing, tasks working hard, , cores maxing out. when happens, "realtime" thread (which runs on 100% cpu core), starts drop packets, because doesn't enough cpu time. the question: it possible somehow "reserve" 1 core "realtime" thread, , limit other threads (tasks) other cores? of course, there other processes running, consuming cpu time well, let's assume consume little , constant resources. this real problem can solved "throw more cpu on it"... not option... edit - answering many useful comments: we use winpcap capture packets, can many (many). the "realtime" thread not "realtime" (i think "realtime" processes - in .

i want create java webserver existing web hosting/space ip/port can test socket programming features. have webhosting package @ https://alfahosting.de/ possible socket programming webhosting package? if not possible socket programming webhosting package. how possible? special webhosting packages support socket programming own ip , port? i know if tutorial how set java webserver socket in web hosting package. thanks! most webhosting packages allow host static html pages , cgi (php, perl) scripts. provide jsp , jsf support more expensive regular webhosters. if want code own webserver/socket applications in java need root server package (i, example, use vserver €12,99/month) on such server have direct root access machine, can install software want - have install java runtime engine of choice , go (assuming server's firewall set correctly) - dedicated ip address can directly connect servers java programs.

i want add functionality when user creates project \ solution in visual studio 2010\2012. i.e. need perform c# code when new project created. i googled lot didn't find event fired on\after project creation. there way that? after research , article mentioned @joe steele, i've managed hook commandevents.afterexecute event, responsible project creation: dte application = this.getservice(typeof(sdte)) dte; string guidvsstd97 = "{5efc7975-14bc-11cf-9b2b-00aa00573819}".toupper(); int cmdidnewproject = 216; this.createcmd = application.events.commandevents[guidvsstd97, cmdidnewproject]; this.createcmd.afterexecute += this.command_afterexecute; and how delegate looks like: void command_afterexecute(string guid, int id, object customin, object customout) { // place code here } notes : probably difficult part find right guid , commandid , this article of help. sometimes, during debugging, event didn't fire @ all, made me baffled, thank

when enter following code: def word_feats(words): return dict([(word, true) word in words]) print(word_feats("i love sandwich.")) i output in letters instead of words {'a': true, ' ': true, 'c': true, 'e': true, 'd': true, 'i': true, 'h': true, 'l': true, 'o': true, 'n': true, 'i': true, 's': true, 't': true, 'w': true, 'v': true, '.': true} what doing wrong? thanks! you need explicitly split string on whitespace: def word_feats(words): return dict([(word, true) word in words.split()]) this uses str.split() without arguments, splitting on arbitrary-width whitespace (including tabs , line separators). string sequence of individual characters otherwise, , direct iteration indeed loop on each character. splitting words, however, has explicit operation need perform yourself, because different use-cases have differen

i've been developing jquery plugin involves making cors ajax calls. development work started inside of plain html page. able open file (right click, open [browser]) in chrome, firefox, , ie7+ , bring data company's dev server (using https). the issue came when started integrating plugin new web forms page. ran through iis time, , ajax call came "error: access denied" in ie <= 9, worked fine in ie10, 11, chrome, , firefox. in fiddler, compared requests sent out html page opened file , html page run through iis. opening plain file, request contained origin http header set null. under iis, request did not have origin header, had referer header set localhost. i've read ie 8 , 9 have partial support cors, while ie10 has full support. what don't understand why cors ajax calls work in ie 7/8/9 when opened html page plain file , not work when run through iis. has else come across issue? referer header that's making throw access denied error?

i hitting obstacle again , again... join each , group each clauses can't used on output of window functions is there best practice or recommendations how use window functions (over()) large data sets cannot processed on single node? fragmenting data , running same query different filters can work, limiting, takes lot of time (and manual labor) , costly (running same query on same data set 30 times instead of once). referring jeremy's answer bellow... it's better, still doesn't work properly. if take original query sample: select title,count (case when contributor_id<>leadcontributor 1 else null end) different, count (case when contributor_id=leadcontributor 1 else null end) same, count(*) total ( select title,contributor_id,lead(contributor_id)over(partition title order timestamp) leadcontributor [publicdata:samples.wikipedia] regexp_match(title,r'^[a,b]')=true ) group title now works... but select title,count (case when contributor_id
