i have x-label range this: 2.0237*e^10 15.055*e^10. when draw graph x-label values overlap. how can manage without changing font size? use "set xtics" define larger distance between xlabel major tics. can use "set format x " define more suitable format x-axes: for example: draws xlabel tics @ 2*e^10, 4*e^10, 6*e^10... set xtics 2e10 this display label tics in more compact form: set format x "%1.0e" you might find helpful: http://heim.ifi.uio.no/inf3330/scripting/doc/gnuplot/kawano/tics-e.html#3.1

i trying create binary tree using generic typing , have error not understand. tried 2 ways of coding , second worked. not understand why first failing. i have following common code: public class mytreea <t extends comparable<t>> { class bt_node<t extends comparable<t>> { t value; bt_node<t> left; bt_node<t> right; bt_node(t node_value) { this.value = node_value ; left = null; right = null; } } the difference in insert procedure: works: private bt_node<t> insert(bt_node<t> node, bt_node<t> newnode) { if ((node.value).compareto(newnode.value) == 0) { . . . } but fails private bt_node insert(bt_node node, t value) { if (value.compareto(node.value) == 0) { . . with: mytreea.java:28:

i have 4 sessions of r, each running different piece of software, between must change often. helpful if colour of console background (or text) different depending on code loaded, automatically, locate window on (cluttered) desktop , avoid typing in wrong commands wrong console in fast moving financial activities. any way within r code? menuing , changing colours manually it's tedious, that, under windows, r colour dialogue box 4 lines deep , there 500 colours. this not direct answer question, might still helpful. using multiple workspaces solve problem. if have different r sessions running, having them on different workspaces (or desktops) separates them nicely. platforms work on (os x , linux) have native support workflow, there must tools windows (a few years there @ least).

like developers think striving create optimal code , database schemas. however - ive got feeling, im on engineering database schema want create. i have web app that, in short space of time, hold lot of users. users in form of customers, suppliers, system users. in industry grow rapidly. in previous schemas have users separated in different tables. however, thinking of going down route of having 1 table called: people. there these tables: people, contact details, residences they related via pivottables ie: pivotcontacts pivotresidences. my question considered good/bad design.? on thinking, on engineering simple setup. the table people grow exponentially , hold alot of data - , other tables relate it. i welcome opinions. will design scale 100 thousand records , maintain moderate speed.? * start 1000 records , grow approx 100,000 in 1 year. for users can log-in, , maybe traced (last login, failed password retries) optimal have small table , maybe separa

i'm trying create function finds how many elements bigger first element divided 2 in given sorted list. example given list [3,3,4,5,6,7,8,9,11] , first element 3 , numbers larger divided 2 7,8,9,11 function returns 4 . i have done far doesn't work. a element first of list , given in order easier. fun findlarger [] = | findlarger [] = 0 | findlarger [x] = 0 | findlarger (x::xs) = let val = ref a; in if !a < x/2 length (xs) + 1 else findlarger (a, xs) end i don't know start pointing out issues code. seems have misunderstood basics of functional programming. first off should not using references (unless know doing, @ still wrong), should use recursion. you haven't declared function take same number of arguments. in first clause, have defined 2 curried arguments, in rest of clauses have 1 argument, , in second last line of code, calling function pair argument. your first function clause don't have body. &quo

if have multiple java threads writing same socket instance simultaneously, affect integrity of objects read same socket? i.e., whether contents of objects messed etc. it's fine ordering of objects random. in general, there no guarantees. bits of different objects end getting interleaved on wire, rendering result indecipherable. therefore, need provide external synchronization. it interesting note single socket write @ os level not atomic. further discussion, see is safe issue blocking write() calls on same tcp socket multiple threads? , be careful sendmsg() family of functions .

i used qprocess execute exe file in qt on windows xp. works normally, while not on windows 7. think it's because of uac issue on windows 7(or windows vista). can me solve problem please? in advance. , here's code: qprocess p(0); p.start("cmd", qstringlist()<<"/c"<<"copy .\\tmp\\gameskoreclient.exe .\\gameskoreclient.exe"); you start process correctly, receive results, have wait until process finished. add line after started process: p.waitforfinished(); and close precess afterwards: p.close()

i created stored procedure performs series of operations require special permissions, e.g. create database, restore database, etc. create stored procedure with execute self ...so runs sa. because want give sql user without permissions ability run these commands have defined. but when run stored proc, get the server principal "sa" not able access database "model" under current security context. how come sa can't access model database? ran code in stored proc on own, under sa, , ran fine. read extending database impersonation using execute as before continue. when impersonating principal using execute user statement, or within database-scoped module using execute clause, scope of impersonation restricted database default. means references objects outside scope of database return error. you need use module signing . here example.

i need create map enum keys small fraction of enum constants inserted. best approach? enummap inefficient if length of underlying array equal total number of enum constants. i suggest using ordinary hashmap . computing hashes enums both easy , cheap. there should no significant memory overhead, since not duplicating enum objects, instead creating multiple references same object. reason, there should little difference between storing integer key , storing reference enum object.

i made 2 database connections in database.php , 1 reading localhost machine , 1 writing "insert" online database. but ran problem when wanted join 2 tables "answers" in localhost database , "user" in online database. function get_users() { $write_db = $this->load->database('default', true); /* database conection localhost db */ $read_db = $this->load->database('read', true); /* database conection online db */ $read_db->select('*'); $read_db->from('ibitstore.user'); $write_db->join('english.answers','ibitstore.user.user_id = english.answers.user_id'); $query = $read_db->get(); if($query->num_rows() > 0) return $query->result_array(); return array(); } when use $write_db join clause $write_db->join('english.answers','ibitstore.user.user_id = english.answers.user_id'); data retrieved online

i got qeustion core data , rules of relationships. i have entitie multiple users. users have optional one-to-many relationship entitie called event. on app start create user (i self) , other users , save them in cd. object of user i m , hold in nsuserdefaults. so, created event , want assign userobject entitie saved in core data. thought use user object saved in userdefaults , add event it, here: event *event = (event *)[nsentitydescription insertnewobjectforentityforname:@"event" inmanagedobjectcontext:managedobjectcontext]; //property setters event.createdby = userobjectfromnsuserdefaults; is right way? assign event specific user (in example me) ? another qeustion is: my event class (subclass of nsmanagedobject) has nsset property add , remove methods add/remove invitedusers or acceptedusers event. how use methods right? any gets cookie :=) about first question - yes, thats way make relationships in core data. assign specific object (nsmanagmentob

i have application in .net need log. want log events , exceptions. saw online log4net being heavily recommended purpose. set begin logging txt file. but not enough purposes. within application, i'd able pull monitor has live listing of logs being generated. if log4net best approach this? if not, is? i have no problem consuming log events , finding own way display data, don't know best way send logging events monitor form. you may want @ log2console , excellent logging monitor compatible log4net. can listen log4net remoting appender , present data quite nicely. if need implement own monitor within program, suggest trying out memoryappender . there's helpful info here (the question nice tutorial) as can see, has set 2 appenders - 1 logging file , 1 logging memory appender. in monitor, can handle appender using following code: hierarchy hierarchy = logmanager.getrepository() hierarchy; memoryappender mappender = hierarchy.root.getappender("memory

the simplest way ask question code: struct point { int x; int y; int z; int* as_pointer() { return &x; } // works int (&as_array_ref())[3] { return &x; } // not work }; as_pointer compiles, as_array_ref not. cast seems in order can't figure out appropriate syntax. ideas? i find array types easier deal with typedef: typedef int ints[3]; then as_array_ref must written &as_array_ref() == &x . the following syntaxes possible: plain c-style cast int* ints* : ints& as_array_ref() { return *( (ints*)(&x) ); } c++ style reinterpret_cast (suggested @mike seymour - see answer). considered better practice in c++: ints& as_array_ref() { return *reinterpret_cast<ints*>(&x); } cast int& ints& shorter (for me) less intuitive: ints& as_array_ref() { return reinterpret_cast<ints&>(x); }
