i making tic tac toe game. works fine except can't determine condition should write in order re-take invalid move. this how move taken (there public method call these 2 private methods.) private string gethumanmove() { scanner in = new scanner(system.in); system.out.println("enter move: "); string str = in.next(); return str; } private string getcomputermove() { system.out.println("enter move: "); random r = new random(); int r_row = r.nextint(3) +1; int r_col = r.nextint(3) +1; string str = string.valueof(r_row)+ string.valueof(r_col); return str; } this isvalidmove() method public boolean isvalidmove(string move) { int row = (int)(move.charat(0)-'0'); int col = (int)(move.charat(1)-'0'); if(board[row-1][col-1] == ' ') { return true; } return false; } i tried using while loop within isvalidmove() didn't work. please show me how input move again?

i'm trying simplify parcelable code in kotlin: public class c() : parcelable { var b1: boolean = false var b2: boolean = false var b3: boolean = false var i1: int = 0 var i2: int = 0 val parcelbooleans = listof(b1, b2, b3) val parcelints = listof(i1, i2) override fun writetoparcel(p: parcel, flags: int) { parcelbooleans.foreach { p.writeboolean(it) } parcelints.foreach { p.writeint(it) } } private fun readfromparcel(p: parcel) { parcelbooleans.foreach{ = p.readboolean() } // not compile "it" "val" } // ... parcel creator bla bla } writeboolean() , readboolean() extension functions. is there way have foreach on list assignable "it"? update: in comment 1 of answers author clarifies question as: my point list not mutable, elements inside are. elements properties. i'm realizing maybe, listof making value copy of properties… either must rely on reflection, or w

so if have 1 list: name = ['megan', 'harriet', 'henry', 'beth', 'george'] and have list each value represents names in right order score_list = [9, 6, 5, 6, 10] so megan = 9 , beth = 6 (this dictionary way) how sort name alphabetically keep score_list matching name? have done sorting numbers using bubble sort method not strings. you can sort them @ same time tuples using zip . sorting name: tuples = sorted(zip(name, score_list)) and then name, score_list = [t[0] t in tuples], [t[1] t in tuples]

i'm using following query: select id,link,size files status='-1' order id desc limit 10 then want change 'status' column values of selected rows -2, possible combine 'select' , 'update' functions in same query don't have query database again? you not need combine select update: try: update files set status='-2' status='-1' order id desc limit 10; the fields names irrelevant here.

this question has answer here: in java, difference between default, public, protected, , private 25 answers i new java, please tell me - "what purpose of protected variable , method in java". thanks in advance. jp. take @ docs following table shows access members permitted each modifier. access levels modifier class package subclass world public y y y y protected y y y n no modifier y y n n private y n n n so, protected elements in java application accessible form subclasses, class , classes in same package! , knowing this, should use protected when methods or attributes of 1 class needs shared around. if don't want leaking of internal state, declaring member variables private way go. if don't care subclasses can access internal

the code have calls openlog() once, before altering effective uid/gid of program (a daemon). security standpoint, or predictability standpoint, calling openlog() after setting effective uid/gid better? i'm guessing on platforms openlog() open unix socket syslogd? permissions on restrictive allow socket opened system users. perhaps has specific case openlog requires elevated privileges, found none (and have in mind lynx , used have in compiled-in default features - til 2009 ). daemons (see this page) not have run root, , use feature. the book the hacker's handbook: strategy behind breaking , defending networks cites openlog , associated functions vulnerability, which allow attacker inject "counterfeit" syslog messages log file given that, ensuring there no weaknesses in application doubly important (since there possibility of becoming agent of other program's intrusion). so answer seems no, there may no need this, dropping privile

i want loop through x items want loop through 2 of items wait response function when done start loop on. so, 2 loops run @ given time until items haven finished. best efficient way accomplish this? the news single-threaded nature of javascript works advantage here. bad news if work requires form of asynchronous input, you'll have a) write thread-blocking/locking code, or b) creative recursion , settimeout. the simpler solution (a) goes this. let's assume need prompt user every 2 loops continue operation. for( var i=0, n=0; < 10000; i++, n++ ){ if ( n == 2 ) { /* example of thread blocking operation "confirm" function blocks thread, loop stop executing until user clicks "ok" */ if ( !confirm("keep looping?") ){ break; }; // reset n fires again in 2 iterations n = 0; } } of course, if work doesn't require asynchronous input user or ajax call, better. fortunat

i'm trying create shiny app allows people input data. make data usable i'm trying remove column has instance of string in dataframe df. task simple in python in r has become quite tough. my first try df[ ,colsums(apply(df, margin=c(1,2),fun=is.character))==0] the problem apply implicitly calls as.matrix (as understand it) make dataframe mixed values is.character drops every column if column has string in it! i tried few loops go through each cell , try drop column has been failing well. any or pointers superbly helpful! you cannot have column of mixed types (at least not in r). column can have numeric, character or factor values, not values different types. have check if columns character or not, , not every single value. try: df <- data.frame(c1 = 1:10, c2 = letters[1:10], c3 = sample(10, 10), c4 = letters[sample(10,10)], stringsasfactors = false) df[!sapply(df, is.character)] c1 c3 1 1 4 2 2 10 3 3 5 4 4 6 5 5 7 6 6 3 7 7 9 8

i'm working on large scientific code run non-interactively on cluster. code uses singleton scheme store large matrices in memory, repeated future multiplications. lately code has been crashing, after allocation of type of these matrices, our exception handler returning output this: ## std::bad_alloc caught in terminatehandler ########## new ran out of memory. peak rss memory = 905179136 bytes current rss memory = 905179136 bytes ####################################################### each process ought have @ least 16 gb of ram available it, difficult see how running out of memory @ 905179136 bytes; furthermore, manipulating code use more or less memory results in program still crashing, smaller (larger) value 'peak rss memory' reported. i can think of 2 possibilities: memory fragmentation. a large 'new' request being made reason, such exceed 16 gb if serviced. it may relevant cuda ap

the current database i'm using "primarydatabase" has collation " sql_latin1_general_cp1_ci_as ", while "secondarydatabase" i'm trying access has collation " arabic_ci_as " i changed collation secondarydatabase , set " sql_latin1_general_cp1_ci_as " , made sure has been changed in tables. however, when run query below still collation conflict. select * [myserver].[secondarydatabase].[dbo].[secondarytablename] ltrim(rtrim([secondarytablename])) not in (select ltrim(rtrim(primaryfieldname)) primarytablename primaryfieldname2=1) one way make query work use collate clause in order apply collation cast on both fields being involved in predicate of where clause: select * [myserver].[secondarydatabase].[dbo].[secondarytablename] ltrim(rtrim([secondaryfieldname])) collate sql_latin1_general_cp1_ci_as not in (select ltrim(rtrim(primaryfieldname)) collate sql_latin1_general_cp1_ci_as primaryt

i trying prove 4^n not in order of o(2^n). is valid method ? 4^n >= c*2^n => 4^n/2^n >= c => 2^n >= c i got lost here... well, method concrete. should proceed in same direction. currently, don't have better option. 4^n = ((2^2)^n) = (2^2n) = (2^n) * (2^n) > 2^n values of n>0. as, (2^n) * (2^n) > o(2^n) . this because (2^n) * (2^n) > c * 2^n. therefore,there doesn't exist constant value greater 2^n! hence, 4^n != o(2^n) 4^n > 2^n values of n>0 .

i'm having trouble showing modal ember. i've followed cookbook when click button modal, shows overlay , not modal itself. here's gist: https://gist.github.com/sunocean-sand/e11111cea44274417012 i appreciate help! i've got similar implementation in 1 of apps. try changing routes/application.js code below. believe problem you're not using bootstrap's programmatic api . export default ember.route.extend({ actions: { openmodal: function(modal) { this.render(modal, { into: 'application', outlet: 'modal' }); return ember.run.schedule('afterrender', function() { ember.$('.modal').modal('show'); }); }, closemodal: function() { ember.$('.modal').modal('hide'); return this.disconnectoutlet({ outlet: 'modal', parentview: 'application' }); } } });

i'm working on project calls circular progress bar. found 1 trick here: http://codepen.io/shankarcabus/pen/gzafb but need animate on page load go in value each time: <div class="progress-pie-chart" data-percent="43"> so on "page1.htm", need data-percent value automatically increase incrementally 0-20. on "page2.htm" 20-33, etc. i'm pretty new jquery, have no idea begin on that. how create function increase data-percent value on say, 500 milliseconds? using setinterval can produce like. use math calculate steps based on fps create smooth animation. decimals can used percent var start = 0; var end = 30; var time = 800; //in ms var fps = 30; var increment = ((end-start)/time)*fps; $('.progress-pie-chart')[0].dataset.percent = start; var timer = setinterval(function() { $('.progress-pie-chart')[0].dataset.percent = parsefloat($('.progress-pie-chart')[0].dataset.percent
