Firebase - update a spacific fields of single element of object of array in firestore  Its actully advisable to use map instead of array when ever it is possible. But, there are cetain cases where you don't have option to do so.  For example, you are directly saving the response from some outer source without any modification and they send you an array. In this case you will have array to work with. Firestore does not support array here is why  "bad things can happen if you have multiple clients all trying to update or delete array elements at specific indexes. In the past, Cloud Firestore addressed these issues by limiting what you can do with arrays " For more details information you can refer to Kato Richardson post Best Practices: Arrays in Firebase .  Firestore document having array [ used from stackoverflow question ] Suppose you have array of object something like shown in array. Now you want to update endTime field of the object on the inde...

In golang there is no direct way [ atleast i don't know ] to find count of differance in days between two days. So, I do it the way might every one does [ except who has already faced this ]. Partial Solution What I does is just find out duration differance of two dates using sub function. differance := time.Now().Sub( startTime ) daysCount := int(differance.Hours() / 24.0) It might seem ok. But, there is a problem with this solution.  Let assume, startTime is 2018-02-02 23:59:59 .   In this case daysCount will be 0 on next day [ 2018-02-03 ] until time is 2018-02-03 23:59:59. Perfect Solution Simple solution is just normalize startTime to starting of that date . normalizedTime := time.Date(startTime .Year(),startTime .Month(),startTime .Day(), 0, 0, 0, 0, time.Local) differance := time.Now().Sub( normalizedTime ) daysCount := int(differance.Hours() / 24.0) normalizedTime is startTime but at starting of date. So, Now we are subs...

Remove console screen for your gui application written in go Images of appliaction used as example is notepad plus minus. I writen as example. To get details of this program you can visit post " Simple document based application with golang " You write a GUI application and it runs with a console screen behind. It looks pretty weird, right! I mean what is the meaning of a console when console actually not going to interact with the user.  GoLang Gui Application with Console Screen Don't know how this works on Mac or Linux as I have not done this on either Mac or Linux. But for windows, I find a way to compile console-less GUI application for golang.  Just build the application with this argument. go build -ldflags "-H=windowsgui" ldflags used to set build time variable. Now. in the upper statement we are saying golang that current application we are building is windowsgui application so don't create the console with it. J...
