could 1 give explanation on how dht works? nothing heavy, basics. ok, they're fundamentally pretty simple idea. dht gives dictionary-like interface, nodes distributed across network. trick dhts node gets store particular key found hashing key, in effect hash-table buckets independent nodes in network. this gives lot of fault-tolerance , reliability, , possibly performance benefit, throws lot of headaches. example, happens when node leaves network, failing or otherwise? , how redistribute keys when node joins load balanced. come think of it, how evenly distribute keys anyhow? , when node joins, how avoid rehashing everything? (remember you'd have in normal hash table if increase number of buckets). one example dht tackles of these problems logical ring of n nodes, each taking responsibility 1/n of keyspace. once add node network, finds place on ring sit between 2 other nodes, , takes responsibility of keys in sibling nodes. beauty of approach none of other nod...

objective-c getting wider use due use apple mac os x , iphone development. of favourite "hidden" features of objective-c language? one feature per answer. give example , short description of feature, not link documentation. label feature using title first line. method swizzling basically, @ runtime can swap out 1 implementation of method another. here explanation code. one clever use case lazy loading of shared resource: implement sharedfoo method acquiring lock, creating foo if needed, getting address, releasing lock, returning foo . ensures foo created once, every subsequent access wastes time lock isn't needed more. with method swizzling, can same before, except once foo has been created, use swizzling swap out initial implementation of sharedfoo second 1 no checks , returns foo know has been created! of course, method swizzling can trouble, , there may situations above example bad idea, hey... that's why it's hidden feature...

i'm here looking @ c source code , i've found this: fprintf(stderr, _("try `%s --help' more information.\n"), command); i saw underscore when had @ wxwidget, , read it's used internationalization. found horrible (the least intutive name ever), tought it's weird wxwidget convention. now find again in alsa source. know comes from? it comes gnu gettext , package designed ease internationalization process. _() function string wrapper. function replaces given string on runtime translation in system's language, if available (i.e. if shipped .mo file language program).

is there way change default number formatting in r numbers print way without repeatedly having use format() function? example, have > x <- 100000 > x [1] 100,000 instead of > x <- 100000 > x [1] 100000 well if want save keystrokes, binding relevant r function pre-defined key-strokes, fast , simple in of popular text editors. aside that, suppose can write small formatting function wrap expression in; instance: fnx = function(x){print(formatc(x, format="d", big.mark=","), quote=f)} > 567 * 43245 [1] 24519915 > fnx(567*4325) [1] 2,452,275 r has several utility functions this. prefer "formatc" because it's little more flexible 'format' , 'prettynum'. in function above, wrapped formatc call in call 'print' in order remove quotes (") output, don't (i prefer @ 100,000 rather "100,000" ).

what sql mode in mysql (or rdbms)? best option have sql mode , why? if have layman explanation example great! thank in advance ;-) the sql mode affects how mysql behaves in situations. example, affects happens if try insert overlong content text type column. let's have column char(10) character set ascii not null , , try insert 'abcdef abcdef' . that's 13 characters, long. if current sql mode includes strict_trans_tables or strict_all_tables , mysql not insert value give error message. if neither of these on, mysql truncate string 10 characters, i.e. 'abcdef abc' , , insert that. there lots of other behaviours affected sql mode. example. i use traditional , shorthand for, well, link given dcp tell you. basically, makes mysql less forgiving when send invalid input, find preferable because if send mysql that's not valid i'd rather know it, rather have mysql fudge , not tell me it's done so.

i'm editing web project uses spring , need adding of spring's annotations. 2 of ones i'm adding @requestbody , @requestparam . i've been poking around little , found this , still don't understand how use these annotations. provide example? controller example: @controller class foocontroller { @requestmapping("...") void bar(@requestbody string body, @requestparam("baz") baz) { //method body } } @requestbody : variable body contain body of http request @requestparam : variable baz hold value of request parameter baz

i'm using messagebox class show errors users, , while might not right behavior, it's convenient. touchscreen application, however, need 'ok' button larger (curse inordinately large fingers!). i think if increase font size in dialog box, should ok. there way that? or really, there way increase dialog size? thanks as far i'm aware can't, 'normal' dialog boxes using default system font settings. roll own best way forward. it's trivial do, , fun! , can build in things standard dialog doesn't support (without pinvoke magic) such centering in middle of screen etc.

i'm using 3.5 sp1 on machine, while our customers use 3.5 without sp1. don't know way in vs2008 target solution or project 3.5 without sp1, 3.5 sp1 have installed. if use functions or constructors not available in 3.5 w/o sp1 code not work properly. that is, want detect @ compile time not work without sp1. so far have done testing (in vm or separate machine) see if application breaks, , break when we've used parts of api not available until sp1. problem breaks when code runs (at runtime), not when assembly loaded. one solution have machine vs2008 w/o sp1 , try compile project. i'd prefer tool me detect dependency 3.5 sp1 (due use of new api, or whatever), either analyzing source code, or assemblies produce. my google powers has not been strong enough question, hints? i had same problem, , found solution. our application, call system.threading.waithandle.waitone(int32) got in trouble. more details on how references api's introduced in service ...
