QUESTION
Having a large data.table that stores one date column (monthly) and then a bunch of different variables of interest measured at the respective dates for various subjects/IDs. Now I want to add for a subset of those variables (only some columns) newly computed columns that lead AND lag those columns by multiple periods all at once. Is that doable? See below for the illustration of some example data that represents the high-level structure of my table and for what I tried so far

I am trying to create a local streaming server with nginx rtmp module. The server itself seems to be working fine as I can stream to server with OBS. Server is storing .ts video files under "/usr/local/nginx/sbin/hls" directory but it does not creates a m3u8 file associated with them.
Configuration file is as follows;

I'm using Nginx v1.17.6
on Ubuntu 16.04 (xenial) as a caching reverse proxy which listens on 443 and proxies requests to backend
upstream. Other example_ip's uses the same configuration as this server. The backend
servers communicate with each other on port 888 which is for cache exchanging between them through a Load Balancer (LB). (Also the LB is for proxy requests to file servers too).
This is my nginx.conf :

Answered 2017-Nov-28 at 06:59Is it possible that the response data may have arrived correctly and was converted as a character string so that it is considered to have ended with zero?
Please check the content of byte array data using BitConverter.ToString()
instead of Encoding.ASCII.GetString()
.
QUESTION
How i can trigger a scanner remotely form my application ? the DirectIO commands provided with device does not contain any command could do that and with some search over google i found my device actually supports this kind of commands but i didn't find any find any thing useful.
Note 1:i am open to any suggestion could help.
Note 2: I've sent a request for the Technical support in Datalogic website but still no reply.
...ANSWER
Answered 2018-Dec-07 at 14:45It would be better to describe the desired usage in detail.
For example, if you set the scanner to Always On or Stand Mode, reading can be started by writing the DeviceEnabled property to true, and you can stop reading by writing false to the DeviceEnabled property.
That way, it seems that software was triggered.

QUESTION
I'm trying to compose one query to get all incoming and outgoing vertices, including their edges and directions, which would however return those vertices without edges as well.
I was able to work around the problem for now by forcing everything to have at least one edge, but it's something I'd like to avoid.
Maybe worth noting that I use the Graph API of Azure CosmosDB: https://docs.microsoft.com/en-us/azure/cosmos-db/gremlin-support
This is the query I'm using to return all vertices with their edges and related vertices:
...ANSWER
Answered 2018-Jan-13 at 20:18Try this
g.V().hasLabel("User").as("User").bothE().as(“edges”).map(select(“edges”).inV().fold()).as("RelatedObjects").select("User", "RelatedObjects",”edges”)
QUESTION
If you could shed some light for me i would appreciate it.
So, basically i am pulling a stream from my encoder and it works, i get the m3u8 output and it is accesible but the HLS video is jumpy and i lose frames. the play is not continuous.
...ANSWER
Answered 2017-Jun-15 at 17:33**OK So.. i have news. Basically that configuration was perfect. The reason why i was losing all these packages was because of the distance between the encoder and the dedicated server.
Advised to have the server locally where the encoders are... So, that for me worked.
Cheers**
