on active directory can subtree , 1 level ldap search using following filters: base dn: cn=users,dc=local,dc=tld filter: (samaccountname=dummyaccount) the dummyaccount in users container. can explain me why one-level , subtree work whereas base not? there can base find object? when perform base ldap search, reading properties of object specify base dn, nothing else. a base search useful if want read properties of single object , know dn. in case, set base dn dn of object, specify attributes you'd retrieved , provide "dummy" search filter ( because filter cannot ommited ) - (objectclass=*) . you can of course use filter ensure dn reading conforms expectations: might know dn, want ensure object reading user, i.e. then, search filter may used.

i want know if array of int elements declared in c. there pattern according values of array assigned 0 while others store garbage values? ex: #include <stdio.h> void main() { int a[5]; int i; (i=0;i<=4;i++) { printf("%d\n",a[i]); } } after compile , run program output,i.e. 0 0 4195344 0 2107770384 so zeroes there in a[0], a[1] , a[3] while a[2] contains same value each time compiled , run whereas a[4] value keeps on changing (including negative numbers). why happen fixed indices of array initialized 0 , have related past allocation of memory space? this behaviour undefined , merely coincidence. when declare array on stack , not initialize array take on values (likely previous) stack frame. aside: if wanted zero-fill array declared on stack (in constant time) can initialize using following initialization syntax: int arr[ 5 ] = { 0 }; it write first element 0 , zero-fill rest of elements. however, if declare...

i'm trying add smaller cube/mesh (with specified side length) 3d scatterplot. i'd cube positioned @ origin. how go doing that? i've played around cube3d() can't seem position cube right nor make mesh (so can see data points contains. here's have: library(rgl) x <- runif(100) y <- runif(100) z <- runif(100) plot3d(x,y,z, type="p", col="red", xlab="x", ylab="y", zlab="z", site=5, lwd=15) there cube3d function default returns list object (but not plot it) represents cube spanning x:[-1,1]; y:[-1,1]; z:[-1,1]. if apply color sides, solid default. need make sides transparent 'alpha" (see ?rgl.materials ). if start out plot used: library(rgl) x <- runif(100) y <- runif(100) z <- runif(100) plot3d(x,y,z, type="p", col="red", xlab="x", ylab="y", zlab="z", site=5, lwd=15) c3d <- cube3d(color="red", alpha=0.1) #...

if i'm using background-size: cover , want make sure image looks on retina macbook pro has resolution of 2880x1880, need make image resolution, or need double resolution because it's retina (as in when have image in site @ 800px x 400px displayed @ 400px x 200px ensure looks on retina). .bg { color:#ccc; background-attachment:fixed; background-repeat: no-repeat; -moz-background-size: cover; -webkit-background-size: cover; background-size: cover; margin: 0; padding: 0; } thanks - appreciated. make images approximately resolution of device. want adjust bit browser/webclip chrome final image size bit different. see custom icon , image creation guidelines more information. additional background retina display devices have devicepixelration of 2 - ration of physical pixels device independent pixels. quirks mode : dips abstract pixels used feed information width/height media queries , meta viewport device-wid...

what should using if (on multicore system) wanted make kernel module function ran 1 core @ time? said in other words, avoid 2 cores running same function @ same time; aka, 1 of cores should wait other 1 finish running function. mutex? spinlock? else? you need use variants of spinlock() i.e raw_spin_lock_irqsave(), raw_spin_lock_irqrestore() ( https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/include/linux/spinlock.h#n188 ), not mutex() cause they're sleep-able, might wake on other cpus. , spinlock make sure code won't executed other cores. it's been documented in linux kernel tree @ documentation/spinlock.txt ( https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/documentation/spinlocks.txt ).

1.why size of derived4 class shows 8 bytes ?? class empty {}; class derived4 : virtual public empty { char c; }; 2.while size of derived2 class shows 4 byte ?? class empty {}; class derived2 : virtual public empty {}; note sizeof(any_class) implementation-defined. but happens in case. well, using virtual inheritance, implementations use hidden pointer implement feature cost sizeof(pointer) bytes (the pointer stored in derived class itself), plus sizeof members (if any) , plus padding if necessary , plus sizeof base class(es) (which reduced zero, in case of empty base class, due empty-base-optimization). for more detailed answer, search "padding in c++" on site. find lots of topics on it.

newbie question: if create several shape objects in loop, like: var i:int; (i = 0; < 3; i++) { var circle:shape = new shape(); circle.graphics.beginfill(color); circle.graphics.drawcircle(100,100, radius); circle.graphics.endfill(); addchild(circle); } how can call different shapes separately , manipulate properties? seem me have same name? you can access them via index (the order have been put on stage). like: displayobject(getchildat(1)).x = 100; // 1 index (starting @ 0)

what throw when not used try , catch? like: if (isempty()) throw "stack empty, cannot delete"; does printed in console? but when throw contains int or char arguments, thrown catch; happens in case? the c++ runtime have along lines of (this not how looks, can think of working way, unless working on special): void beforemain() { try { int res = main(); exit(res); } catch(...) { cout << "unhandled exception. terminating..." << endl; terminate(); } }
