i've began learning mongodb research project i've been working on. i've gotten comfortable querying on command prompt, , command prompt in general, need way of making interactive, user-friendly tool people in workplace interact data (i.e. data, filter, etc.). in other words, expecting them use command prompt isn't option project. said, i'm not sure how go accomplishing this. appreciated! you can use robomongo. please refer www.robomongo.org more details

a read-only data descriptor descriptor defines both __get__ , __set__ , __set__ raises attributeerror when called. an example simple read-only property: class test(): _i = 1 @property def i(self): return self._i assert hasattr(test.i, '__get__') assert hasattr(test.i, '__set__') t = test() t.i # 1 t.i = 2 # error if have instance of class, can determine if instance attribute read-only data descriptor way (although don't @ all): def is_ro_data_descriptor_from_instance(instance, attr): temp = getattr(instance, attr) try: setattr(instance, attr, none) except attributeerror: return true else: setattr(instance, attr, temp) return false if know class doesn't require arguments instantiated, can determine if class attribute read-only data descriptor similar above: def is_ro_data_descriptor_from_klass(klass, attr): try: setattr(klass(), attr, none) except attributee

my question simple i've not been able find answer or work out solution myself. i'm using few libraries in projects (e.g. holoeverywhere, viewpagerindicator, etc.), , move between computers often, send projects colleagues, etc. anytime this, library references messed , have redo them. isn't more hassle, rather have library references self-contained rather having use references folders on drive. i've tried exporting libraries jar files , including in build path project no avail. that's thing i've thought do, have no clue how else accomplish this. basically, want able have library contained in project instead of referencing library projects elsewhere in workspace. possible? thanks help!

i want color of each arrow in quiver3 plot matlab correspond magnitude of each arrow. there way that? i saw few examples online able 2d quiver , none of them work 3d variant, quiver3 . i have following plot , want replace blue arrows color corresponding magnitude. in old graphics system (r2014a , earlier) not possible using built-in quiver object. can of plot objects used compose quiver plot q = quiver(1:5, 1:5, 1:5, 1:5); handles = findall(q, 'type', 'line'); but tails represented 1 plot object, , arrow heads represented another. such, can't alter color of each head/tail individually . set(handles(1), 'color', 'r') set(handles(2), 'color', 'g') however, introduction of hg2 (r2014b , later), can access two (undocumented) linestrip objects ( matlab.graphics.primitive.world.linestrip ) (one represents heads , 1 represents tails). these accessible via hidden properties tail , head . q = quiver(1, 1, 1

why 'sizeof' operator return size larger structure total sizes of structure's members? this because of padding added satisfy alignment constraints. data structure alignment impacts both performance , correctness of programs: mis-aligned access might hard error (often sigbus ). mis-aligned access might soft error. either corrected in hardware, modest performance-degradation. or corrected emulation in software, severe performance-degradation. in addition, atomicity , other concurrency-guarantees might broken, leading subtle errors. here's example using typical settings x86 processor (all used 32 , 64 bit modes): struct x { short s; /* 2 bytes */ /* 2 padding bytes */ int i; /* 4 bytes */ char c; /* 1 byte */ /* 3 padding bytes */ }; struct y { int i; /* 4 bytes */ char c; /* 1 byte */ /* 1 padding byte */ short s; /* 2 bytes */ }; struct z { int i; /* 4 bytes */ sh

what's difference between shallow , deep static analysis? i'm using xcode @ moment, , noticed there's build setting distinguishes between two. i'm curious in general case, , i'm wondering if there's difference in how clang implements distinction. i tried google-foo , couldn't find answer. tried going through apple , clang docs see if explain didn't find anything. didn't miss obvious stone overturn in searching. (1) talk apple's evan cheng (compilation tech) gives indication (see pages 157/158): shallow - quick analysis deep - more thorough analysis recommendation: always analyze in deep mode part of qualifications (2) more details can find in source code of analyzeroptions there usermodekind variable: 00184 /// \brief describes kinds high-level analyzer mode. 00185 enum usermodekind { 00186 umk_notset = 0, 00187 /// perform shallow fast analyzes. 00188 umk_shallow = 1, 00189 /// perform deep a

i send request through aws ec2 api stop (or start) instance , callback when machine in stopped state (or running ). i'm using aws sdk .net, , i've tried ec2client.stopinstancesasync method. returns request has posted, does not make asynchronous callback after state transition. what i'm aiming overall stop instance, change instancetype once machine stopped , start instance. appears way might make stop request, start own polling mechanism watch instance state transition stopped , continue instancetype change once has completed. i'd love think there's simpler, less chatty way of waiting transition complete. know of way notified when ec2 state transition has completed? it looks answer no. there appears no way notified when ec2 instance transition has completed. polling way accomplish this.

recently installed noscript plugin in firefox control execution of javascript. noticed websites use fancy unicode charaters place holders images, replaced images once allow javascript. 1 example site github.com, see screenshot taken before enabled javascript. what's advantage of instead of place image directly in html or css? the sites using icon font (or more one). an icon font regular font file contains images. it's technique cut down on http requests , enable other features. now, how or why that's defeated noscript plugin, don't know. ( edit — it's apparently configurable noscript option, selected default. @font-face rules blocked, ostensibly security reasons.) in github sample, quick trip developer tools shows there's font called "octicons".

i've got space invaders style game works okay when press key move player's ship, aliens slow down until key released. because there's more code being run when key pressed if there isn't (obviously). here's code that's run when press key keys = pygame.key.get_pressed() if keys[pygame.k_up]: objship.move(1) elif keys[pygame.k_right]: objship.move(2) elif keys[pygame.k_down]: objship.move(3) elif keys[pygame.k_left]: objship.move(4) which calls following code def move(self, d): self.direction = d if self.direction == 1: self.image = pygame.image.load("shipu.png").convert() if self.yco >= 0: self.yco -= 1 if self.xco >= 884: self.xco = 860 is there way of way of equalising speed of aliens doesn't involve putting wait command (or empty loop or whatever) else statement act make-work delay? i can put code here it's bit lengthy @ moment thought i'd try wit

this did i'am not sure if right int e = 1; int m = 500; ( e = 1; m = 500; e < 4; m >= 300; e++; m-100;) what trying is possible, have few pieces wrong. you can execute multiple statements in each "area" of for-loop structure, need separate them differently. valid loop this: for ( e = 1, m = 500; e < 4 && m >= 300; e++, m -= 100) { } notice in first , third blocks, use commas separate initialization , increment/decrement statements. second block has single conditional, used && , them together. i fixed "m" decrement statement modified m. subtraction operator non-destructive, wouldn't modify n original code.

i'm writing first app makes use of azure mobile services platform. have sql server configured , table showing on azure management portal. have manually added entries table ensure nothing wrong on server-side. my problems lie in fact app hangs when perform query on table. here's code: public mumanager(context con){ context = con; try { log.i("counter", "before mclient"); mclient = new mobileserviceclient("https://blah.com","apikey",context); log.i("counter", "after mclient"); mutable = mclient.gettable("table1",muitem.class); } catch (malformedurlexception e) { log.i("counter", "malformedurl"); e.printstacktrace(); } log.i("counter", "end of constructor"); } now, i'm not having issues above code, have no way of confirming client connecting azure mobile service. below code causes issue.

is possible android's videoview read mp4 file skip first 512 bytes? our client not want videos transferred/copied on different devices. did "obfuscate" mp4 file adding random 512 bytes @ beginning of file , renaming files different file extension. obviously, above approach not protect videos being pirated. he's fine enough protection "non-techies". currently, upon playing video, our android app extracts actual video content new temporary file skipping first 512 bytes. temp file 1 played videoview. the problem takes long time our videos more 100mb+ each. not acceptable solution. i think, if can make videoview skip first 512 bytes, we're set. possible? if not, better alternatives? disclaimer: i'm web developer of server app adds 512-byte padding. i'm not android developer. i'm posting question on behalf of android dev colleague. forgive me if our approach totally noob. feel free suggest better (and hopefully) easy ways.
