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. ...

i have 2 tables in database, fleets , personnel_onboard_fleets. trying list of of fleets (which works) , count how many personnel onboard each fleet (which doesn't). however, isn't showing results if there aren't personnel onboard. select f.*, count(pof.id) onboard fleets f, personnel_onboard_fleets pof f.fleet_id = pof.fleet_id order f.status i expecting 2 results, 1 fleet 2 people on board , 1 0 people onboard. 1 result. have tried use following select f.*, ifnull(count(pof.id), 0) onboard fleets f, personnel_onboard_fleets pof f.fleet_id = pof.fleet_id order f.status i cant see wrong query, there else needs added show fleets 0 persons onboard. my original query before count shows fleets fine, know count. this driving me crazy! appreciated!! try: select f.fleet_id, count(pof.id) onboard fleets f left join personnel_onboard_fleets pof on f.fleet_id = pof.fleet_id group f.fleet_id order f.status;

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 .
