a user has arraylist of numbers. numbers correspond applications have access to. applications have different entitlement numbers(ie- 3, 72, etc.). want store data in map when user logs in, can input numbers map , applications entitled to. however, applications require 2 3 entitlement numbers. example, 1 entry be: ("101 , 234", "application 1"). wondering if there ideal way of retrieving of values map that users entitlement numbers satisfies. how have it, program compares users data each application , confirms or denies access. seems inefficient. appreciated! note: reading applications , numbers in xml, can store them wish. if there large numbers of numbers required per application, best approach use set intersection. if numbers contiguous or @ least dense, can optimize bitset. 1 or 2 numbers though, i'd recommend testing each number individually, since it's faster full set operations.

i interested in doing c code in java: // sets n's ith bit right, starts 0 void setbit(int* n, int i){ *n = *n | (1 << i); } however, looks java can't pass addresses, clean approaches? i thought of 2 approaches, wondering if there better ways it? approach 1: using array // sets n[0]'s ith bit right, starts 0 public void setbit(int[] n, int i){ n[0] = n[0] | (1 << i); } approach 2: using class private class data{ int value; } // sets d.value's ith bit right, starts 0 public void setbit(data d, int i){ d.value = d.value | (1 << i); } nope, no better way it... unless you'd traditional java way, is d = setbit(d, i); public int setbit(int d, int i) { return d | (1 << i); } this in java "modifying arguments function" inherently unclean. clean way find alternative modifying arguments. (sometimes it'll inevitable, in case workarounds way go. said, if want write method modify(mydata)...

i writing program in actionscript 3 involves slider displays weeks , months on course of year slide right in format of "month 2 week 3" or "month 8 week 2". did months this: function monthhandler(){ var a:number = ((math.ceil(aslider.value/4))+1); monthlabel.text = "month" + string(a); } however same slider (aslider) i'd display weeks, 4, each month. know need set number threshold; values 1-4 display weeks: 1-4, values 5-8 have display weeks 1-4. i know using crapton of if() loops relatively new programming , assuming there more efficient way of doing this, , not know it. looked around web checking multiples of numbers, , setting number thresholds, nothing seems suited problem. the current code weeks is: function weekhandler(){ var b:number = ((math.ceil(aslider.value/12))+1); weeklabel.text = "week:" + string(b); } all display 1-4 slide slider across quarters of thing. said, know doesn't work don't know fix it. ...

for many kinds of hard computational problems e.g. propositional satisfiability, theorem proving, traveling salesman etc., there exists extensive test suite can used evaluating performance of program attempts solve problem. does such thing exist automatic bug finding, i.e. collection of programs or code fragments containing known bugs of kind automatically detected? assume e.g. coverity must have such thing internal use, google search doesn't seem show publicly available. i don't think such suite exists. glaring question "standard" suite is, language written in? for c, can @ safecode 's test suite, here . safecode meant detect these bugs @ runtime, "perfect" static analysis tool should able detect them statically. a more comprehensive, , more importantly, static analysis tool, frama-c . see paper entitled " test-driving static analysis tools in search of c code vulnerabilities ". paper describes need test suite ask for. links...

i'm using sphinx code documentation , use several languages within code, setup highlighting of code. sphinx briefly mentions few of languages supports ( on page ), , mentions uses pygments lexical analysis , highlighting. sifting through documentation both sphinx , pygments yielded me no clue on how highlight objective-c code. pygments mention list of languages supports, here , doesn't tell me exact syntax must use within sphinx (.rst files) tell code block highlight specific language. example, highlight c++ code simple use before code block: .. highlight:: c++ however after trying these cannot seem highlight objective-c code: .. highlight:: objective-c .. highlight:: objective-c .. highlight:: obj-c .. highlight:: obj-c can supply me list of languages (as refer them within documentation)? as far can tell, list in file pygments/lexers/_mapping.py , in (autogenerated) dictionary lexers . in copy, see line 'objectiveclexer': ('pygments.lexers...

in eclipse, enumerate content every registered provider. there such interface? at least in installation not search files @ all. instead same old "ctrl-3" quick access allows access ui elements typing name. try "pack" see listing package explorer , similar things. for locating files should use ctrl-r (open resource) instead or use normal file search.

i need allow administrators manage permissions models on site. groups, users, , permissions doing great job of right now. however, need allow administrators manage permissions of non-authenticated users - anonymous users. docs anonymous user's group empty, how can allow administration of permissions? it strange add permissions anonymous users. docs say: django's permission framework not have place store permissions anonymous users. however, has foundation allows custom authentication backends specify authorization anonymous users. useful authors of re-usable apps, can delegate questions of authorization auth backend, rather needing settings, example, control anonymous access. so can set permissions anon yuser, custom auth backend. better use declarative permission check, using decorators on views needed permissions, like: @permission_required('somemodel.can_add') def add_model(request): or leave unrestricted everyone(incl. anonymou...

i trying optimize function (say find minimum) n parameters ( xn ). xi 's bound range (for example -200 200 ) , if parameter leaves range, function goes infinity fast. however, n can large (from 20 60-70 ) , computing it's value takes long time. i don't think details about function of big relevance, here some: consists of weighted sum of 20-30 smaller functions (all different), on part consist of sums of dot products under sign of inverse sinusoidal function ( arcsin , arccos , arctan , etc). arcsin(x1 . x2) + arcsin(x4 . x7) + ... . the function has many local minima in general, approaches such (naive) conjugated gradients or quasi-newton useless. searching entire domain brute force slow. my initial idea use sort of massive parallelization in combination genetic algorithm, performs many searches on different spots in domain of function, , @ regular intervals checks whether of searches reached local minima. if yes, compares them , discards results smallest o...

i have prerequisites: a, b, , c , want build f (final) i can write make rules ( create , update different each command) f : b c create a1 create a2 a1 create a3 a2 create b1 b create f c update f b1 update f a3 or f : c b1 a3 create f c update f b1 update f a3 b1 : b create b1 b a3 : a2 create a3 a2 a2 : a1 create a2 a1 a1 : create a1 any idea reliable, fast ? more granularity in makefile desirable. if 1 of jobs in pipeline fails, can correct error , pick make died. additionally, rules easier read. the form single rule , many commands faster in execution because fewer timestamps checked , fewer rules need evaluated; however, time difference inconsequential.

a typical workflow me opening vim (macvim precise), doing: :nerdtree <bookmark> then manually opening various subdirectories want use. it's same set of directories had open when last working on project. i'm aware of o recursive-open command if it's large tree have go , close load of them clear screen up. is there way of saving ones open / general 'state'? unfortunately, there no way in nerdtree - yet. if feel feature deserves attention, however, can add yourself or submit request it on github, , available soon. edit: took liberty of submitting feature request myself; you can track status here .

still getting know orchard, i've managed create custom default page using module , routing rules. although orchard shows page, renders 3 seem default widgets, headings "first leader aside", "second leader aside", "third leader aside". ok apparantly need overwite default behaviour or that, can't figure out how. so there wrong / missing module, or need provide setting or that? if widget in default layer, appear on every single page in site. see http://docs.orchardproject.net/documentation/managing-widgets you need put these widgets in different layer defined rule fits want.

is there way can actionbar views object references. instance overflow view in order know coordinates on screen. have manage ugly solution is. menu item id overflowview =((viewgroup)parent.findviewbyid(r.id.menu_id).getparent()).getchildat(2); is there way can actionbar views object references. only ones create yourself, via android:actionlayout , kin. for instance overflow view in order know coordinates on screen. your solution unlikely remain stable across android versions. may or may not work on actionbarsherlock. recommend find other solution whatever perceive problem not involve messing around internals of actionbar implementation.
