in qt there q_assert macro. what's advantage of using instead of assert <cassert> ? q_assert custom assert macro supposedly enhances standard assert function. the error message handled qfatal() , can behave better on platforms standard assert macro. example on windows trigger visual studio debugger @ point assertion fails instead of calling abort() . you can redirect output of qt error message functions such qfatal to custom message handler ( qinstallmessagehandler() ). can useful example if want redirect errors message file. also note q_assert disabled macro qt_no_debug (while assert disabled ndebug ) : can used separate asserts between qt-related code , rest.

i doing research on concatenating char primitive values form string , came across post: concatenate chars form string in java i understand correct way of producing final string value use tostring() method, how come if not use method, still same output. have thought following code output heap address of object sb still prints 'ice'. thank you. public class charstostring { public static void main (string args[]) { char a, b, c; = 'i'; b = 'c'; c = 'e'; stringbuilder sb = new stringbuilder(); sb.append(a); sb.append(b); sb.append(c); system.out.println(sb); } } you need system.out.println(sb); does. calls in class java.io.printstream method.

i implementing .net web api 2 in c# using. works fine, send username , password , bearer token returned. now token used other api calls, in each call know user data. because app call web api such python code etc, in such cases send bearer token not user name. i tried dig through code not locate it. any ideas appreciated here. the answer depends on type of bearer token you're dealing with. example, if jwt token, consists of 3 parts separated period: header, payload, , signature. user id payload, you'll need base-64 decode payload , grab "sub" property. 'sub' known 'claim'. token contains many claims 'sub' typically stores user id. see more details: https://jwt.io/introduction/ in c#, can parse out payload of token using string.split() , base 64 decode payload this: var payload = encoding.utf8.getstring(textencodings.base64url.decode(b64payload)); from there, need deserialize payload object matches format expect:

we use activesupport notifications log specific network calls (with faraday). in 1 of types of calls, when code reaches activesupport::notifications.subscribe(notification[:name]) |_name, starts, ends, _, env| handle_notification(starts, ends, env, notification[:service], env[:request_headers][notification[:header]]) end the starts , ends same, can't calculate duration of call. since happens 1 specific call, , code same, notice calls work extracted gems, calls aren't working no in gems. not sure if matters how can debug/solve this? the start , end values time objects. if log output of values appear time/date value 2017-01-12 10:51:00 +0100 . you have convert milliseconds or microseconds see fine values. you can convert time object milliseconds following: start.to_f * 1000 end.to_f * 1000 then can work values 1484216765256 in milliseconds , calculate duration subtracting end start .

i have 2 tables - sensors , readings . there 1 many relation sensors readings . i need query rows sensors , newest (i.e max timestamp) data readings each row. i've tried with: select sensors.*, readings.value, readings.timestamp sensors left join readings on readings.sensor_id = sensors.id group readings.sensor_id the problem is, have 6 million rows of data , query taking 2 minutes execute. there more effecient way can hold of last reading/value each sensor? this how i'd go problem: it involves trigger populates latest_readings table it involves table named latest_readings . the table i made sensor_id unique because assumed have one reading per sensor. can categorized types adding additional column. reason unique index: we'll using mysql's insert ... on duplicate key update have hard work done us. if there's reading particular sensor, gets updated - otherwise, gets inserted (in 1 query). you can make sensor_id foreign key. sk
