how 1 find out status of lock keys on linux (2.6.x), using c? (i have crappy keyboard without led's stuff, , need write x11 app this) if such app exists ( and de agnostic - run e16), i'd hear well. you can use led addon gkrellm. if want develop own app, can gkrellm-led sources (ubuntu). and, of course, can go xkbvleds (source) . anyway, can use xkbgetindicatorstate read indicators keyboard.

subquestioning [2] while copying resource.mdf [1], noticed that: 1) possible copy resource.mdf without stopping sql server instance (i attached 1 having copied running instance , works after attaching) . 1a) should understand general possibility read-only databases or in versions (mine 2008 r2 on windows xp pro sp3)? 1b) conceptually, cannot understand why developing (dev ed) sql server on isolated/workgroup desktop windows (in case - xp pro sp3) should stopped in order copy user-defined non-used (for ex., sample database) database. 1c) when 1 should copy .ldf .mdf file , when copying .ldf can skipped? why read-only database have (transaction log? understood) file ldf? 2) resource.mdf (in sql server 2008 r2 on default unnamed instance, windows xp pro sp3) in %programfiles%\microsoft sql server\mssql10_50.mssqlserver\mssql\binn\ and not in %programfiles%\microsoft sql server\mssql10.sql2008\mssql\binn\ [2] i curious - location differing due sql serv...

trying set import form live database our development database. i trying using ssis, import failing because of constraints. e.g. have following tables: * customers * products * orderlines * orders importing customers , products fine, because not depend on anything. when importing orderlines fails because order not yet created. how change order of how ssis imports tables? or maybe i'm not supposed use foreign key constraints? it sounds have foreign key constraints. want load orders table before load orderlines table. i'm assuming have single ssis package contains 1 data flow task each target table. need create connection between data flow loads orders , data flow loads orderlines. connection called precedence constraint. select orders data flow , should see green arrow. click , drag arrow orderlines task. creates precedence constraint indicates orders data flow must complete before orderlines dataflow can start.

if client sends multiple messages server on same socket, endreceive on server side keep messages seperated, or possible the server receive partial messages 2 seperate sends in single beginreceive? assuming tcp, there're no message boundaries on socket. 1 send might consumed multiple receives , other way around, , partially. treat tcp socket stream. either send fixed-size messages know how many bytes read, or embed message size message (preferably @ beginning of message) can find out go. edit: to answer questions in comment - it's not "ms os" that's doing - it's tcp/ip stacks on both sides of connection. bytes written socket buffered inside kernel , sent on wire when network stack thinks it's best time (in-kernel timeout up, output queue reached tcp window size, etc. - it's in details of how tcp works). tcp (but not udp) kernel not keep track of application write boundaries, of how many bytes there send, how many have been ack-ed, etc. ...

this question has answer here: how returning output of function different printing it? 4 answers in python don't seem understanding return function. why use when print it? def maximum(x, y): if x > y: print(x) elif x == y: print('the numbers equal') else: print(y) maximum(2, 3) this code gives me 3 . using return same exact thing. def maximum(x, y): if x > y: return x elif x == y: return 'the numbers equal' else: return y print(maximum(2, 3)) so what's difference between two? sorry mega noob question! the point return not function. control flow construct (like if else constructs). lets "take data between function calls". break down print : gives value user output string. print(3) give string '3' screen user view. progr...

i'm delving couchdb, , puzzled distribution of map-reduce computations in views. see lot of resources mentioning map-reduce inherently distributed, because can process 1 half of data on server a, other half on server b, , reduce both results. 1 example slide 16 of presentation: http://www.slideshare.net/gabriele.lana/couchdb-vs-mongodb-2982288 this seems logical, but: couchdb not seem provide api dispatching computations several servers. distribution appears provide replication of entire data set other servers (which then, assume, compute own view data). couchdb uses b-tree store view data based on keys generated in map step of view algorithm, precludes appropriate partitioning of documents based on server should on. so, couchdb distribute map-reduce computations @ all? or map-reduce property used merely cache values in b-tree nodes? you looking bigcouch , enables couchdb cluster , uses distributed mapreduce.
