i made python script goes through files in whatever directory placed in , renames them based on criteria. script works perfectly, , compiled script os x .app using py2app. worked fine well. when run script, searches through files in ".app/contents/macos" folder (where script located) rather ".app" located. this because has code @ start: src = os.path.dirname(os.path.abspath(__file__)) which assigns the location of ".py" file variable used extensively throughout script. there way can instead add snippet of code tells python path location of ".app" ".py" file executing from? if not, perhaps there way file explorer window open, there possible user select folder who's path assigned "src" variable. i'm new python challenge. try use: import os print(os.getcwd()) from docs: getcwd() return unicode string representing current working directory.

hi using telerik report view generate report. all good, have mapped data data source , report looks great in design view. but when view in preview pane duplicates table x times number of rows have returned. know why ? you have duplicate table cause datasource bound page item. so lets quick. 2 solutions , choose one! use gui apply filter on table. filter on unique data. : =fields.myfield_id_xyz = =reportitem.dataobject.myfield_id_xyz in code behind : this.table2.filters.add( new telerik.reporting.filter( "= fields.myfield_id_xyz" , telerik.reporting.filteroperator.equal , "=reportitem.dataobject.myfield_id_xyz" )); this prevent duplication of table. filtering on reportitem.dataobject.myfield_id_xyz , current row of detailsection .

i'm bit confused language used in spec concerning descriptor bindings described vkdescriptorsetlayoutbinding struct. binding element is binding number of entry , corresponds resource of same binding number in shader stages. as stated in 14.5.3 a variable identified descriptorset decoration of s , binding decoration of b indicates variable associated vkdescriptorsetlayoutbinding has binding equal b in psetlayouts [ s ] specified in vkpipelinelayoutcreateinfo so if correctly descriptor bindings described vkdescriptorsetlayoutbinding must have entry every active resource variable in set. resource variable referred each descriptor binding dictated binding variable , binding decoration of each variable. so far good. confusing part when calling vkupdatedescriptorsets . struct vkwritedescriptorset has element dstbindng is descriptor binding within set. i'm confused whether dstbindng 's value must same binding number used decoration in var...

sorry question don't understand how works: class person { public static $age = 1; public function havebirthday() { static::$age +=1; } } $joe = new person; $joe->havebirthday(); echo person::$age; what i'm not understanding this: public function havebirthday() { static::$age +=1; } isn't supposed return $age otherwise value lost? why still working? thanks! you've defined static , means class level variables instead of instance level. so when call $joe->havebirthday(); updates class level variable of person class can accessed using person::$age; . static variables not need returned, can access directly class.

i'm rewriting code java swift , need break multi-layered switches right way. in java looks : block0 : switch (topswithch) { case one: { switch (innerswitch) { case insidecase: { if (something){ break block0; } // etc so, i'm breaking 1 switch another. how do in swift ? this it'd in swift. did in playground hardcoded values variables: let topswitch = 1 let innerswitch = 4 let 1 = 1 let insidecase = 4 let = true block0 : switch (topswitch) { //first switch labeled "block0", switching on topswitch case one: //topswitch 1, 1 one switch (innerswitch) { // switching on innerswitch case insidecase: // both 1 if (something){ // if true break block0; // break "block0" } default: break // else } default: break // else }

suppose, enter 15 in computer. numeric value. how computer can convert numeric value electric signals like: 1 -> true-> pass electricity 0 -> false -> don't pass electricity experts numeric value converted in binary. think 1 thing, computer electric machine , there flow of electron, nothing else. how type of machine can convert number electronic signal? if cannot understand question ask me. there plenty of literature , ressources on how computer works. try wikipedia, youtube, google find suits level of understanding. for question alu might of special interest: https://en.wikipedia.org/wiki/arithmetic_logic_unit also read memory, control unit , transistors. a computer nothing combination of memory, processors , data busses. super miniaturized electronic circuit. a modern cpu alone comprises 3-5 billion!!! transistors. you can store logic states (bits) https://en.wikipedia.org/wiki/flip-flop_(electronics) compare them https://en.wikipedia.org/...
