some installation applications stop (or appear stop) normal windows booting. computer starts, user logs in , installation program starts before others (like windows explorer). how can replicate behaviour in own program? e.g. os boot login the program runs, updates etc. the rest of programs run (e.g. windows explorer , ever runs on startup) if want start application before shell starts, can add value userinit value in registry. in key: hkey_local_machine\software\microsoft\windows nt\currentversion\winlogon there value named userinit . change program run before userinit.exe. example, start notepad before shell/everything else initialized: c:\windows\system32\notepad.exe,c:\windows\system32\userinit.exe use commas separate programs should started. this works windows xp, vista, , 7.

bankers algorithm - How do I determine whether a deadlock will occur in this system? -

-
n processes share m resource units can reserved , release 1 @ time. maximum need of each process not exceed m, , sum of maximum needs less m+n. can deadlock occur in system ? the system describing looks semaphores about last question : yes. "could" deadlock ; if don't see how, ask young/shameful/motivated/deviant developer. one way make 1 ; have strange locking/releasing resources rules. example, if process needs m resources perform task, locks half of them right away, , waits other half available before doing anything. i assume never gives until have m precious resources , releases them once task done. a single process wouldn't cause problems several lock more m total resources , need more of them out frozen state.

i student , want build own .net language general purpose, see how done, , learn new. you think better choice? build static language targets clr or build dynamic language on top of dlr? what steps in process of building these 2 kinds of languages different? what available tools generating scanner, parser , cil code? found people recommend antlr parser generator generating ast, , translating dlr expression tree, doesn't need generate cil code. i recommend antlr, , book it. unless know grammar generation, you'll need reference material. i recommend using antlr ast generate codedom. use dlr or not, depending on kind of language want make. i've had great success both routes though. i've generated cil, wasn't awesome did work. leave last resort.

i'm not mathematician may stupid question...but - there way translate ip addresses integers between 1 , 3, whereby there a) equal distribution of 1's, 2's , 3's , b) each ip address translate same integer? (in essence, hash). i'm using 3 example - ideally i'd range limit customizable. $highest_allowed_integer = 3; $integer = get_evenly_distributed_but_always_identical_integer($_server["remote_addr"],$highest_allowed_integer); thanks! treat entire ipv4 address number in base 256 (that means 4.3.2.1 translate (4 << 24) + (3 << 16) + (2 << 8) + 1 ), mod 3, , add 1. on little digression, might want concept of hashing .

objective c - Increasing width of UISearchDisplayController PopOver Results -

-
i have ipad app has uisearchbar in navigation bar. when enter text in search bar results automatically displayed in uipopovercontroller. that's great except popover's default size not wide enough needs. there way set width? apple has done safari's search bar. popover displays search results bit wider default , have removed "results" title popover. you'd need set contentsizeforviewinpopover property of uiviewcontroller that's being displayed in popover. i'm not sure how if it's automagically happening behind scenes.

php - How can I get PhpStorm to go to the right declaration -

-
i have following snippet of code. abstract class mrparent { public function __construct() { $this->var = 'a'; } } class mrchild extends mrparent { public function hello() { echo 'hello'; } } $mrguy = new mrchild(); now, in phpstorm, when middle-click ("go declaration") on last line of "mrchild" class, cursor jumps "__construct" line. expecting go "class mrchild extends mrparent" line. in single document, ok, in setup it's 1 class per file, quite annoying because means ide showing me class don't want. i know if added following code "mrchild" class, i'd want, seems shouldn't fixing consider ide bug adding code. public function __construct() { parent::__construct(); } do have suggestion? you facing wi-4880 issue. feel free watch/vote.

Alternatives to SQL? (Alternative declarative query languages for relational databases?) -

i came across htsql , reminded me of question i've wondered: alternative declarative query languages relational databases out there? complaints exist against sql, i'd expect many, googling has been unfruitful. various programming languages have list/monad comprehensions, i'm looking more actual implementation relational databases. great highlight major differences vs. sql (readability, modularity, concision, etc.). implementation needs open-source, , ideally can use against existing rdbms, e.g. postgresql. here's complete list, links illustrative example code (moved examples in question down here): muldis d : terse perl-inspired syntax; designed practical full scripting language. htsql : terse; optimized foreign key joins; limited expressiveness. mdx : the multidimensional expressions (mdx) language provides specialized syntax querying , manipulating multidimensional data stored in olap cubes.[1] while possible translate of these traditional sql
