I am trying to read and write using a network connection. What seems to be happening is some data is being discarded or lost if data comes in too quick to the server. The client connects, negotiates a connection, then I have it send 3 commands in quick succession to update a status page. Each communication is a JSON string that is translated to a struct and decoded with a stored key.

If I click the request on the client several times (each generating 3 \n-terminated JSON payloads), the server at some point will throw an ERROR: invalid character X after top-level value. I dumped the information being sent by the client and it looks like 3 properly formed JSON entries on the client side; on the server side, it looks like one of the JSON payloads is missing completely and one of them is missing the first 515 characters. Because the first 515 characters are missing, the JSON is malformed, therefore the marshaling fails.

My question is, what can I do to prevent the loss of data reads from the connection? Am I hitting some kind of race condition or mishandling how to read and send on the connection?

Below is basically what I'm using for the client connection handler. The client and server negotiate an encrypted connection so there are several references to mode and RSA status, and mode 4 is used when the keys are properly set so the server and client can exchange commands and results. At a high level, the handler spins off a goroutine that reads from the connection and sends it to a channel. That string is read and converted to a struct. The first part of the session is dedicated to a "handshake" to negotiate an encryption key and save the session information; once stage 4 is reached the struct carries encrypted commands from the client and sends the results back until the connection errors or is closed.

I have a function that allows me to import spreadsheet data from my gmail to Google Sheets. Previously, the spreadsheet data had only had 6 columns to import. Now, some new changes are made and a 7th column was added. After this change was implemented, my function no longer works and Google Sheets throws this error. May I please have some assistance?

So, as I'm looking at this, the intended functionality looks right to me. Skip the first 3 rows (netdata) and take everything below. Could it be the + 1, 1 ?

I am trying to implement a concurrent TCP server in Go and found this great explanatory article in linode where it clearly explains with a sample code. The sample code snippets for the client and server and included below.

Concurrent TCP server where for each TCP client a new go-routine is created.

I was running Ubuntu server 20.04 quite successfully with Ired mail and 2 websites, one of them with WordPress.

I wanted to install Nextcloud, to do that I had to reinstall php-fpm to generate php7.4-fpm.sock. After this Nextcloud worked, but my other websites stopped working with error '502 Bad Gateway'.

So to say the least, I'm very confused!

I followed this article to install Nextcloud and set up the sites-enabled .conf file as per instructions: https://www.linuxbabe.com/ubuntu/install-nextcloud-ubuntu-20-04-nginx-lemp-stack/amp

I think I understand that the .conf file used to listen on 127.0.0.1:XXXX and now listens on php7.4-fpm.sock?

Here is the .conf file that I have put together for my website after re-installing php-fpm:

I have installed iRedMail on my server and it is managing my emails perfectly. I would like to use this server also as website server. I went into the nginx config /etc/nginx/sites-enabled/ 00-default-ssl.conf 00-default.conf

when I add www.mywebsite.com.conf it doesn't seem to be render.

mywebsite is not deploy, my nginx conf is simple.

Is it related to iRedAdmin config? since the file 00-default-ssl.conf use the templates. Does the templates in nginx override the conf file ?

Is there something I have missed on my conf ?

Thanks in advance !

I'm following the following guide for installing Netdata on Laravel Forge. Basically, it's opening the port 1999 used for Netdata and redirecting it to /netdata directory.

I want to use sockets. I'm using this package:

https://github.com/tlaverdure/laravel-echo-server

because my domain name has a SSL I should add this config:

https://github.com/tlaverdure/laravel-echo-server#alternative-ssl-implementation

For example, the configuration file is as below:

I have been attempting to create a LINQ query in C# which will allow me to create a List<> from different properties in the JSON string, which are of interest to me.

I have attempted a number of different approaches of .Select() and .SelectMany() but always end up with creating an exception. To unblock I have resorted to creating 2 or 3 independent Linq Queries which will extract the data I care about and then append these to a List.

Of course, this is utterly ugly; and therefore I am here asking from some guidance on how to do this correctly. I am not a professional developer, and IT Pro lost in DevOps; so please be kind!
