i'm new telegram bot. know how use methods send message or others file_get_contents method in php or curl, don't know enough types. although read in telegram page, misunderstood. don't know how use types in bot. want create keyboard bot, think when use curl, should send types parameters. wrote code below : $params = array ( 'chat_id' => $chatid, 'text' => 'hello !', 'replykeyboardmarkup' => array ( 'keyboard' => array(array('hello', 'hi')) ) ); it sends me message when use curl : $curl = curl_init("https://api.telegram.org/bot".$apitoken."/sendmessage"); curl_setopt($curl, curlopt_header, true); curl_setopt($curl, curlopt_returntransfer, 1); curl_setopt($curl, curlopt_post, 1); curl_setopt($curl, curlopt_postfields, ($params)); curl_setopt($curl, curlopt_ssl_verifypeer, false); curl_exec($curl); curl_close($curl); but doesn't show me keyboards ......

i'm learning akka.net. i've set running test i'm running actor locally, , remotely on actor on vm in azure. the problem is, after i'm done , close application locally remote actor goes down. "an existing connection forcibly closed remote host" what need remote actor accept termination, , wait next connection actor running locally. how can fix this? if you're creating actors using remote deployment , actor stopped, once it's parent die (due actor system shutdown). in case, while child living on machine, it's still child of local actor. natural part of actor system lifecycle - children cannot live without parents. if you're interested having actors scattered among cluster nodes , make them rebalanced/recreated automatically, may take @ akka.cluster.sharding plugin. keep in mind, while lot easier, solution more complex , slower solution standard akka actors. make sure need features.

i understand component architecture is, don't understand how different multi-transclusion model. can please explain? the difference components used encapsulate logic , define how custom html element rendered . multi-transclusion is/can part of component. tells where arbitrary text/html/... placed when component rendered. this useful if want create component layout application. think official documentation example that: https://docs.angularjs.org/api/ng/directive/ngtransclude#multi-slot-transclusion

in command line, can add , remove packages raco pkg . in drracket, however, package management handled through either file -> install package (if installing packages), or file -> package manager (if want install package, list of installed packages, etc.). unfortunately, dialog not appear have tag removing package. possible remove package drracket, or must done with: raco pkg remove <package-name> obviously, can indirectly within racket using find-exe : #lang racket (require compiler/find-exe) (system* "-l" "raco" "remove" "<package-name>") but seems clunky. there better way remove packages drracket/ you can remove package going to: file -> package manager , , click on second tab ( currently installed ) see list of of installed packages. select package want remove, , find remove button in bottom right corner. if click button package removed system. here picture of list of installed packages remove bu...

i have followed several django tutorials. not know why controllers stored in file called views.py. confuse filename. looking mvc development. there other files in django "real" controllers ? yes ! it's design decision , it's described guys behind django here . basically argument that, in opinion, in our interpretation of mvc, “view” describes data gets presented user. it’s not how data looks, data presented. view describes data see, not how see it. it’s subtle distinction. a “view” python callback function particular url, because callback function describes data presented. i entice read entry hold of overal idea behind views naming. about controllers, yes again. though, can define several layers of called middlewares in django handle lots of static logic before/after requests handled views, still, it's view plays main role of controller in django.

i've got following code snippet in setup() function: ... unsigned int a0val; unsigned int a0total = 0; ... (i = 0; < 1000; i++) { a0val = analogread(a0); serial.println(a0val); a0total += a0val; } serial.println(a0total); ... this done baseline analog value @ startup account different types of sensors being used. 1 type may read 0 , may read non-zero value. point have starting point reference averaging 1000 readings @ startup time. 1000 overkill, i'll cut later. now, 1000 readings somewhere between 128 , 130, expect a0total around 129,000. however, total consistently comes out less half number, 63,722 in 1 example. it's not half, it's less that. another example: add first 500 readings when around 350-352, , total came out 43614. looks wrap-around, i'm using unsigned int both values can't happening. so me looks "a0total += a0val" not updating every loop, doesn't make sense either. what missing? thanks, ron ...
