[go-nuts] Re: formatting question/issue

I believe the first example (the one without the last comma) is when you want to put everything on the same line. The second example (the one with the last comma) is when you want to split the items into separate lines. They each have different uses. It is awkward to see this `{ 'A', 'B', 'C',

[go-nuts] Anyway to print the exact cql query being executed against db

Hi, Assuming my query using an iterator looks like this. Is there any way to print the exact cql query that is finally executed on Cassandra side when iter.Scan() is called? My iter query is returning empty results, but when I manually search using the cql query in my database table in

Hi Alex: thanks for your answer, really helped me. As you mentioned, the connection was indeed closed by the server side: in the packages captured, the server side sent the FIN first; seems like that python's HTTP module and nginx all close the conenction on server side i wrote a simple http

Is there a way to send an email AS a group member? Currently, I am able to do so via the Gmail Web Client. But I can't figure out a way to do it via my 3rd party client (Airmail 3), or standard Go (via net/smtp). Hence, I was wondering if there was a way to send as a group. On Wednesday,

Re: [go-nuts] Sorting slice of structs

Simple mistake. You have: sort.Slice(arr, func(i, j int) bool { return arr[i].X < arr[i].X }) Instead use: sort.Slice(arr, func(i, j int) bool { return arr[i].X < arr[j].X }) On Tue, Apr 10, 2018 at 12:28 PM, Sankar wrote: > Hi > > I have the following code: > >

[go-nuts] net.Conn not returning error upon Write after being closed from far side.

Hi I'm trying to understand what is going on under the hood here. I would expect a net.Conn after being closed from the far side, to issue an error if the near side then tries to write to it. On my local machine an error is returned on the second write, on the go playground all writes
