i writing large, multithreaded application, many differing roles threads (e.g. event processing, metrics, networking). currently, if there inconsistency cannot handled, manifest exception. since there's no way recover of them, i've been rethrowing runtime exception of type applicationdeathexception . any classes need handle shutdown call catch block exception, , rethrow in order propagate stack). i considering killing off other threads in same manner calling thread#stop(throwable) upon them. fine sudden termination, , can catch exception should there need shutdown logic. have exception propagate stack, performing shutdown logic whereever needed, , killing thread in end. there hidden dangers i'm missing approach? thread.stop has been deprecated since unsafe (see javadoc). instead have each thread monitor boolean flag of sort (see java: how stop thread? , countless other threads on so). in situations typically implement sort of thread pool manager respon

is possible change in init function of class? lets have class called "deck" which, when initialized, creates list of 52 card objects. now want make class called "even" inherits "deck" class , creates deck of card objects eliminates cards number 2 (so spades, hearts, etc) inherited "deck". i have been having lot of trouble because when try modify inherited list, regardless of try, python return error, 'nonetype' being main root of problem. here code "even" class init: def __init__(self): x = deck.__init__(self) card in x: if card.rank() == 2: x.pop(card) return x it worth noting card class has method rank() return rank of card int. regardless of things have tried, there wrong it.

a simple question, quick googling did not prove fruitful. basically, have column called "uniqueid", unique identifier people in dataset. uniqueids have multiple records, because there 1 record per year person stayed @ university. i'd create "time period" variable, first year, t= 1, second year t=2, third year t=3 etc. each unique id. the following faster if spreadsheet sorted unique id; =if(a2=a1,b1+1,1) (assumes above formula in column b , data begins on row 2) and, of course, copied down rows described above. you find in spreadsheet containing many rows countif slow since looking through ever-increasing range sizes.

this question has answer here: unboundlocalerror in python [duplicate] 8 answers i going crazy. simple callback function doesn't recognize variable assigned right before in it's parent scope. local variable 'elapsed' referenced before assignment error`. why? total = os.path.getsize(filename) elapsed = 0 def progress_print(chunk): elapsed += len(chunk) # elapsed apparently unassigned?? percent = float(elapsed) / float(total) * 100 print ' copied %s%%\033[a' % int(percent) ftp.upload(filename, temp_path, callback=progress_print) you're trying assign global. python makes explicitly that. def progress_print(chunk): global elapsed elapsed += len(chunk) in general pretty sign need refactor code until don't need globals more. note assignment , access different beasts - former requires explicitly

i new asp.net , first time using membership controls in project. here in project while creating new user need mobile number of user, how can enable mobilepin of createuserwizard. because saw mobilepin field in aspnet_membership table thinking can add values mobilepin field front-end while creating new user. can me? i did code doesn't work <asp:label id="mobile" runat="server" associatedcontrolid="mobilepin">mobile no:</asp:label> <asp:textbox id="mobilepin" runat="server" cssclass="textentry"></asp:textbox> <asp:requiredfieldvalidator id="requiredfieldvalidator1" runat="server" controltovalidate="mobilepin" cssclass="failurenotification" errormessage="mobile required." tooltip="mobile required." validationgroup="registeruservalidationgroup">*</asp:requiredfieldvalidator> how make mobilepin in asp.net me

i have try math.round class. let see math.round(2.5) //2.0 math.round(-2.5) //-2.0 math.round(2.5,midpointrounding.toeven) // 2.0 math.round(2.5,midpointrounding.awayfromzero) //3.0 my simple question if change number -77777777.5 why result -77777778.0 not -77777777.0 math.round(-77777777.5) // -77777778.0 math.round(-77777777.5,midpointrounding.awayfromzero) // -77777778.0 math.round(-77777777.5,midpointrounding.toeven) // -77777778.0 thanks idea , suggestion. the default midpointrounding mode toeven . in mode, explained documentation (where a input value), the integer nearest a. if fractional component of halfway between 2 integers, 1 of , other odd, number returned. -77777777.5 has 2 nearest integers -77777777 , -77777778 latter 1 1 returned. in awayfromzero mode, -77777778 further 0 -77777777 .

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 .
