there lot of information out there concerning parcelable in android. after looking around, couldn't find nice solution problem. so, need create class (let's call "myclass") extends custom class else wrote ("hisclass"). there many instance variables in hisclass, of objects of custom classes, themselves. want pass myclass object 1 activity , realize, need make parcelable. instance variables custom objects? reading this , think need make every single custom object implement parcelable. since, there many custom objects in myclass , hisclass again have custom objects instance variables, doing seems bad solution me. is there better way? maybe, being totally blind here. hope can me. well, can make use of serializer , result in slow performance. afaik, implementing parcelable best way passing data. additionally, don't try complicate creating complex data structure pass using intent . either use parcelable cheap/light-weight/less-in-amount ...

how can make own custom class sortable using sort() example? i've been scanning web find method of making class comparable in java without luck. tried implementing __equals() without luck. i've tried __tostring(). class looks this: class genre { private $genre; private $count; ... } i want sort them count integer, in descending order... ($genre string) you can create custom sort method , use http://www.php.net/manual/en/function.usort.php function call it. example: $collection = array(..); // array of genre objects // either must make count public variable, or create // accessor function access function collectionsort($a, $b) { if ($a->count == $b->count) { return 0; } return ($a->count < $b->count) ? -1 : 1; } usort($collection, "collectionsort"); if you'd make more generic collection system try this interface sortable { public function getsortfield(); } class genre implements s...

in datagridview, if set grid readonly there black triangle @ rows headers shown @ current row. i'd avoid shown, i'd avoid big padding of cells caused triangle. guess padding caused triangle because cell's padding 0. is posible that? how? thanks! edit this how row headers text created: for (int = 0; < 5; i++) { datagridviewrow row = new datagridviewrow(); row.headercell.value = headers[i]; datagridview1.rows.add(row); } and headers array of strings. ( string[] ) if want keep row headers rather hide them, can use cell padding push triangle out of sight: this.datagridview1.rowheadersdefaultcellstyle.padding = new padding(this.datagridview1.rowheaderswidth); if using row header text , want keep visible need use custom painting - thankfully simple. after above code, attach rowpostpaint event shown below: datagridview1.rowpostpaint += new datagridviewrowpostpainteventhandler(datagridview1_rowpostpaint); and in rowpostpa...

i have following code which, without escaped sql statement, working fine - iterates on full set of returns previous select query printing id, detected language (from bingtranslate) , text. for row in c: lang=bingtranslate(row[0]) tweetid = row[1] print tweetid, lang, row[0] #c.execute('update tweet set iso_language_code=? id=?',(lang, tweetid)) when unescape update call, loops once, , stops. what gives? no error reported. i'm sure it's simple can't crack it... i don't know python, try explain in c#. you're executing command using same object of datareader ( c in python), have reset , strange behaviour. in opinion don't need copy rows in object, create new command object (empty) , use execute query taking params c . correct me if i'm wrong, please.

currently, i'm looking best practice "applying discounts" cart/order. so, i'm planning implement such kind of discounts as... fixed user's discount (for example, i'd give 10% discount favourite customer) discount number of items (for example, you're buying 10 different colored pens , you'll getting discount of 1.5%) discount coupon (for example, during promo action we've produced 100 coupons 10% discount each. coupons work 1 order , expire on yyyy-mm-dd) present purchasing item or group of items (for example, you're buying pen, list of paper , shop presents sharpener you) discount total order price (for example, you're buying 10 pens , gettin no discount, you're adding 5 more pens , getting 5% discount) only 1 discount applied specific item. we're applying biggest discount. profitable discount user. beside admin should able modify items price in specific order , cancel discounts in order. frankly speaking, fir...

given binary mask object in matlab. going find concavity point of object boundary. concavity point mean here deepest concavity point respect euclidean distance convex hull chords k_1, k_2 ,and k_3 in concavity regions b_1, b_2, b_3, respectively. red dot indicates concavity point want find, in concavity region b_1 draw 3 lines perpendicular chord k_1, deepest concavity point middle 1 since has largest length. anyone have efficient way/code that? thanks. another figure below gives example convex hull, red dot indicates valid concavity point. efficient relative... how computing convex hull (there standard algorithms it) , shrinking until inside object boundaries. last point touching desired concavity point. alternative strategy: calculate convex hull find differences between convex hull , object boundary (have straight lines, k1 k2 k3 in case) for every line, rotate image such line horizontal take lowest pixel of object boundary below line

...is possible? for example, can add simple function... public static double deg2rad(double degrees) { return math.pi / 180 * degrees; } ...to convert class? (using default..."usings") can call double radians = convert.deg2rad(123); can done? if so, how? no can't, can add extension method double , call like double x = 180.0; double y = math.cos( x.deg2rad() ); double z = math.sin( 0.5.pi() ); in static class add following extension method: public static class extensionmethods { public static double deg2rad(this double angle) { return math.pi*angle/180.0; } public static double pi(this double x) { return math.pi*x; } }

so normal android project, have following in androidmanifest.xml: <application android:name=".utilities.app" ...> .... </application> and have app class: public class app extends application { .... } and have android junit test project associated android project. fine , dandy , can write junit tests. however, i'm trying run code coverage junit tests , i'm getting bloated results. reason because app class gets called , initialized if application started. not want custom app class execute when run junit tests or code coverage. setup need junit tests go in appropriate junit setup() method. there way can prevent executing custom app class or way classes/methods/lines executed due creation of app class aren't counted towards code coverage? a temporary solution i've found work unless has better ideas. go main android project's androidmanifest.xml. change android:name attribute ".utilities.app" "andro...

hi have project need use java access twitter api, , found twitter4j easy use , tried samples site. cannot find details regarding query class regarding query strings object, knows comprehensive info one? cheers. if "query string" mean value in query field, that's literally text can type search box on twitter's website. there's no list of examples because it's wide open. use whatever happen thinking @ particular instant in time.

i'm using "mypage" plugin trac. i have figured out useful store ssh keys on private page attachment, can clone git repository computer. have our found user can view history tab, can see content of attachment :/ any idea how secure thing? since in general meant feature, you'd block 1 or several specific attachments common view. if true, tracfinegrainedpermissions you. you'll able have like [wiki:users/killdaclickhome@*/attachment/supersecret.file] killdaclick = attachment_view * = !attachment_view to deny access specific file yourself. have @ finegrainedpageauthzeditorplugin alternative way define these permission (from web-ui instead of direct access authz file). you'll think twice granting permission 'trac_admin' - hint these user can edit file , possibly circumvent restriction. 'trac_admin' have 'attachment_view' anyway.

here problem. i have test suite testing few classes. classes use dependency injection. i have class called schedulehandler passes tests. other class rulehandler has method requires instance of schedulehandler. dont want pass in real schedulehandler tried create mock schedulehandler inject in. the problem have because schedulehandler class tested in suite above rulehandler, when mock created get:- php fatal error: cannot redeclare class schedulehandler if dont use test suite, , run tests individually fine. anyone know of way round ? my best guess far: var_dump(class_exists('schedulehandler', false)); returns false you. means class doesn't exist yet. if autoloader doesn't find class when phpunit trying extend phpunit create class it's self. if later down road require real class somewhere classes collide. to test make sure have required real schedulehandler class before creating mock object.

i building system lets users upload shapefiles. converts shapefiles postgis using shp2pgsql . command requires srs id in form of epsg code. so need ruby gem can read shapefile's *.prj file (which contains projection/spatial reference system encoded wkt) , return corresponding srs id. i'm not sure how ruby bindings work gdal, osr (part of gdal) can extract either projection wkt (text) or srid (integer). see this gis.se answer solution python/gdal/osr. update: turns out ruby bindings work nicely expected. going, try code: require 'gdal/osr' prj_fname = 'myfile.prj' prj = file.open( prj_fname ) # import wkt prj file srs = gdal::osr::spatialreference.new() srs.import_from_wkt( prj.read ) # various exports puts srs.export_to_wkt srs.auto_identify_epsg puts srs.get_authority_name(nil) puts srs.get_authority_code(nil) if need other aspect of projection, explore available public methods: srs.public_methods.sort

i have tried exec, system , not able open notepad even. using xampp on windows 7. system("cmd /c notepad"); works here (notepad opened), should realize 2 things: if you're running apache service, won't have notepad windows pop because service running user in non-interactive fashion. it's normal no response long (perhaps indefinitely) because wait program finish. see proc_open or popen more control.

i testing throughput of interface on linux. using dma todo data transfer. dma needs contiguous memory location. kmalloc unable allocate more 1mb. there other way create big buffer location upto 100m bytes? i thought kmalloc couldn't allocate on 128kb, how did allocate 1mb ? anyway, assuming you're working on freshly booted system, can reserve 2048 contiguous pages. pages 4k, makes 8mb. _get_free_pages(_gfp_dma, get_order(2048)); however, if need more memory, should allocation @ boot-time. if writing driver, can achieved alloc_bootmem_* functions. if writing module, have pass mem= argument kernel , later use ioremap . for example, if have 2gb, can pass mem=1gb forbid kernel using upper 1gb, , later call ioremap(0x40000000, 0x40000000) access upper 1gb, you. but know, should split huge buffer many small ones, it'll easier , more real-life applications.

why can't static classes have non-static methods , variables when non-static classes can have static methods , variables? what advantage of having static methods , variables in non static class? though having static constructor in non-static class understandable. static classes can't instantiated in first place, if declare non-static (instance) members, can never accessed. since there isn't point allowing reason, language prohibits it. bear in mind static classes just classes , while there 2 things directly related non-static classes: the classes themselves, , the instances/objects of classes. a non-static class can have both static , non-static members static members apply class, whereas non-static members apply instances of class.

config files have grown complex have suggested their own programming language. if take analogy further, make sense have consistencies when editing file. i going limit question wcf, sensitive smallest configuration change, think other sections (web.config) benefit structure well. given vs2010 handle indentation of file, other standards applicable when updating config file? ideas came : sort <config sections> alphabetically the name identifier within <config sections/> should pushed left alternatively group identifiers , config sections similar function i'm guessing guidance may vary between specialties (web vs wcf vs identity model) i'd appreciate hearing own perspective. i (until forces opposite) sort alphabetically (sections, nodes, subnodes), except sections' declaration, have going first.
