windows - Are Unix/Linux systems vulnerable to leaking global kernel objects? -

-

in windows there're objects maintained system - events, file access handles, windows, timers, etc, not unlimited programs in system can create no more 50k objects (i'm not sure of exact figure, it's not critical question).

so if program runs long time , creates lots of objects , doesn't release them (exactly memory leak, here system objects leaked) system runs out of objects , other programs try requires creating new system objects start getting error indications system functions. example, program runs , leaks objects available system , program b tries open file , fails because system has no resources service request. solution @ point restart program leaked resources reclaimed system.

does same problem exist on unix/linux systems or somehow protected against that?

they're subject same problems, can degree hardened/limited. default, there's limits per process that's way below cause systemwide problems. have start lot of processes though. of these limits can viewed ulimit command. *nixes have possibility set limits on per user basis (see /etc/security/limits.conf on linux systems)

but in cases remove limit, or have whole lot of processes doing bad stuff, system wide total limit bound available resources(memory)

if want demonstration of resource limitation, run this command in bash shell , see if system still usable:

:(){ :|:& };:

c# - How to set Z index when using WPF DrawingContext? -

-
how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

-
i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

visual c++ - Using relative values in array sorting ( asm ) -

-
i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
