how can change spacing of tick marks on axis of plot? what parameters should use base plot or rgl ? there @ least 2 ways achieving in base graph (my examples x-axis, work same y-axis): use par(xaxp = c(x1, x2, n)) or plot(..., xaxp = c(x1, x2, n)) define position ( x1 & x2 ) of extreme tick marks , number of intervals between tick marks ( n ). accordingly, n+1 number of tick marks drawn. (this works if use no logarithmic scale, behavior logarithmic scales see ?par .) you can suppress drawing of axis altogether , add tick marks later axis() . suppress drawing of axis use plot(... , xaxt = "n") . call axis() side , at , , labels : axis(side = 1, @ = v1, labels = v2) . side referring side of axis (1 = x-axis, 2 = y-axis), v1 being vector containing position of ticks (e.g., c(1, 3, 5) if axis ranges 0 6 , want 3 marks), , v2 vector containing labels specified tick marks (must of same length v1 , e.g., c("group a", "group b...

i have created 3 tables in database , put data them. 3 tables have foreign keys joining them together. below table classes , there mappings. when run query listed @ end ilist<> of objects , have data 3 tables. however, hql query top table. how can results top table? these classes: public class technology { public virtual int id { get; private set; } public virtual string name { get; set; } public virtual int sortorder { get; set; } public virtual string abbreviation { get; set; } public virtual ilist<technologydescription> technologydescriptions { get; private set; } public technology() { technologydescriptions = new list<technologydescription>(); } public virtual void addtechnologydescription(technologydescription technologydescription) { technologydescription.technology = this; technologydescriptions.add(technologydescription); } } public class technologydescription { public virt...

what way top 10 records large collection , use custom orderby? if use linq objects orderby method slow , takes lot of memory because creates entire new collection new order. new method signature below not re-order entire collection , fast: public static ienumerable<tsource> orderbytop<tsource, tkey>( ienumerable<tsource> source, func<tsource, tkey> keyselector, icomparer<tkey> comparer, int topcount) i tried write got complicated , thought there might easier way using aggregate or something. appreciated. answer thanks help. ended code below: public static list<tsource> orderbytop<tsource, tkey>( ienumerable<tsource> source, func<tsource, tkey> keyselector, icomparer<tkey> comparer, int topcount) { var itemcomparer = keyselector.toicomparer(comparer); return source.aggregate( new list<tsource>(topcount), (list<tsource> list, tsource item) =...

i have application users can have set of preferences. both stored activerecord-models follows: class user < ar::base has_one :preference_set end class preferenceset < ar::base belongs_to :user end i can access preferences of user: @u = user.first @u.preference_set => #<preferenceset...> @u.preference_set.play_sounds => true but fails if preference set not created, since @u.preference_set returning nil, , i'll calling play_sounds on nil . what want archive user.preference_set returns preferenceset instance. i've tried defining this: class user < .. has_one :preference_set def preference_set preference_set || build_preference_set end end this causing 'stack level deep' , since calling recursively. my question this: how can ensure @user.preference_set returns either corresponding preference_set-record or, if none exists, builds new one? i know rename association (eg. preference_set_real ) , avoid recursiv...

iam using asp.net , asp.net-ajax every thing happens on browser urls of format http://somepage#page1 http://somepage#page2 http://somepage#page3 now these urls in secured folder when logged in user directly types (or use bookmark) url below, shown page http://somepage#page2 -- (bookmarked url lying in secured folder) now when user user not logged in directly type above url gets redirected login page on login page in redirection url iam unable read characters after pound (#) sign. iam getting redirection url= " http://somepage " while want " http://somepage#page2 " there way can this everything after "#" sign in url never sent server won't able read value aspx page.

we have old java swing application. need display thousands, hundreds of thousands small circle spots on canvas based on real data. right have image file of small circle spot. when need it, draw image onto canvas, thousands, hundreds of thousands times. now think may better (better performance , memory usage) draw filled circle each time instead of load image , draw it. how opinion? thanks, you need load template image once , hold in memory , copy canvas needed using graphics2d drawimage function. drawing multiple filled circles may become expensive due calls flood-fill / scan-fill algorithm bresenham draw circle. optimize rendering can decimate rendered result or perform clustering , since user not appreciate dense overlapping circles anyway. to reduce render calls test pixel template going , pass render if coloured. here nice benchmarking applet .

we use infopath 2007 + sharepoint 2007 , need inject javascript infopath form. know infopath form can hosted on aspx page using xmlformcontrol. solution doesn't suit =(. there workaround? infopath form services won't let publish infopath form javascript. if need use javascript rich client experience, may have luck loading form in xmlformcontrol mentioned, loading js library on page along side it, , binding dom elements. won't design time support way may work. generally speaking, need stick rules , managed code ipfs.

i'm using extjs 3.0 , extend formpanel or solution everytime show form, first field should focus. thinking of adding global listener (if such exists) perhaps: afterrender: function() { ext.getcmp('formaddprogpaymentdoc').findbytype('textfield')[0].focus(); //// first textfield , focus } can done ? have more 40 forms , don't want add each 1 listener, it's listener automatically each one. thanks. create extoverrides.js file modify base functionality of ext. , add following code: ext.override(ext.formpanel, { onrender: function(ct, position){ this.initfields(); ext.formpanel.superclass.onrender.call(this, ct, position); this.form.initel(this.body); //begin edit of default functionality var firstfielditem = this.getform().items.first(); if(firstfielditem){ //delay focus 500ms make sure field visible firstfielditem.focus(true,500); } //end edit of def...

i'm working classes which, when throwing, have relatively deep innerexception tree. i'd log , act upon innermost exception 1 having real reason problem. i'm using similar to public static exception getinnermostexception(exception e) { while (e.innerexception != null) { e = e.innerexception; } return e; } is proper way handle exception trees? i think can innermost exception using following code: public static exception getinnermostexception(exception e) { return e.getbaseexception(); }

i have advanced datagrid sorting. think string sorting default. need sorting in number. how can achieve number sorting? for example: have row numbers 1 100 . need number sorting 1,10,100. in advanceddatagridcolumn add sortcomparefunction: <mx:advanceddatagridcolumn sortcomparefunction="numbersorter" sortdescending="true" datafield="number" headertext="formal name" width="280"/> add function somewhere in scripts <mx:script> <![cdata[ import mx.utils.objectutil public function numbersorter(itema:object, itemb:object):int{ return objectutil.numericcompare(itema.number, itemb.number); } ]]> </mx:script>

can point me tutorial on using android scripting enviornment? i've seen plenty of tutorials on how write python code using android api http://code.google.com/p/android-scripting/wiki/tutorials . but none of i've seen gives example of how works inside android or how call python stuff android application. i'm looking tutorial can bring can see example of actual android app running python scripts. note: tested on samsung galaxy s running android 2.2. ymmv. i never thought of running python on android till saw this. :) installed sl4a app , tried out simple shell script. installing python interpreter , trying out hello world soon. the step straight forward: 1. download app (it.s not on market http://code.google.com/p/android-scripting/ ) 2. create shell script clicking add button , choosing shell in options pop-up 3. write code. 4. select "save , run" (or "save , exit" , click on script name in main window) 5. @ point script's out...

some cross-platform packages ruby or qt prefer %homedrive% default installation path, google chrome uses in %homepath%. what's advantage , disadvantage of each choice? what's best choice simple private application (i.e. game, installation should work without administrator rights)? on other end: best choice industrial application (i.e. software controls industrial device, running on computer merely exists purpose)? if want ensure app can installed without admin privs, install under %localappdata% - if want install system-wide, use %programfiles%. whatever do, don't use %programfiles(x86)%.

is possible change number of bytes long has in visual studio? when compiling c code sizeof(int) , sizeof(long) both equal 4. since you're using visual studio, presumably target platform (and libraries you're using) target windows. win64 platform uses llp64 model ( http://msdn.microsoft.com/en-us/library/aa384083.aspx ) int , long 32-bits. futile think try make long 64-bit type in situation. use int64_t (from stdint.h ) or long long or similar 64-bit integer type

i writing script requires checking whether particular commit merge/revert commit or not, , wondering if there git trick that. what came far (and don't want depend on commit message here) check hash^2 , see if don't error, there better way? figuring out if merge easy. that's commits more 1 parent. check that, can do, example $ git cat-file -p $commit_id if there's more 1 `parent' line in output, found merge. for reverts it's not easy. reverts normal commits happen apply diff of previous commit in reverse, removing changes commit introduced. there're not special otherwise. if revert created git revert $commit , git generates commit message indication revert , commit reverted. however, it's quite possible reverts in other ways, or change commit message of commit generated git revert . looking generated revert commit message might enough heuristic you're trying achieve. if not, you'd have through other commits, comparing dif...

i wondering if list/examine databases/objects available in rails console. know can see them using other tools, curious. thanks. you seeking: activerecord::base.connection.tables and activerecord::base.connection.table_structure("projects") you should wrap them in shorter syntax inside .irbrc .

i have heard there different levels of synchronization.are there?(if there ,would please explain them snippet code?)thanks. before java 5 there one: synchronized keyword. waited , obtained exclusive lock on reference object. when applied function: public synchronized void dostuff() { ... } the object being synchronized on this . java 5 added lot of concurrency utils, 1 of lock object. there several versions of including readwritelock . thing can think of might referring to. the problem synchronized crude. done badly can lead deadlocks. java 5 utils allow non-blocking lock acquisition, timeout on lock acquisition , read/write lock support.
