Can I install Docker on Endless Linux?
Pretty soon I am going to work with a team in a Linux environment, where Ubuntu is preferable and we will work with Docker and Symphony. For this purpose I have bought a new laptop and asked the company to install Ubuntu Linux on it.
However, they told me that the laptop came with an installed Endless Linux and they did not manage to install Ubuntu, the installer crashed. So I have two options: I will either install the programming environment on my Endless Linux, or I will have to install a virtual machine on the computer and install the programming environment on that. The latter has some obvious drawbacks, so I would like to install the programming environment on Endless Linux.
The problem is that even though I have been searching for possibilities to install Docker on Endless Linux, I did not find the solution.
My question is: is there a Docker version compatible with Endless Linux?
I came from a Windows environment and do not have extensive knowledge about Docker and/or Linux.

PHP script keeps "restarting" creating new instances of itself
I developed a site using Zend Framework 2. It is basically a price comparison site that integrates with many of the top affiliate networks out there. I wrote a script that checks prices from each affiliate network, and then updates my local DB with that price. Depending on which affiliate network I am contacting, I may be making an API call (Amazon or CJ.com), or I may be looking at an XML product feed (Pepperjam or LinkShare). The XML product feed would be hosted locally.
At present, there are around 3,500 sku's that I am checking with this script. The vast majority of them (95%+) are targeting an XML product feed. I would estimate that this script should probably take in the neighborhood of 10 minutes to complete. Some of the XML files I am looking at are around 8 MB in size.
I have tested this script thoroughly in my local environment and taken great lengths to make sure that there is no memory leak or something of that nature which would cause performance issues. As an example, I made sure to use data streams where possible to avoid putting the XML file in memory over and over, etc. Suffice to say, the script runs locally without issue.
This script is intended to be run as a cron job, however I do have a way to trigger it via the secure admin interface ad-hoc. Locally, this is how I initiate the script to run, and everything goes rather smoothly.
When I deploy my code to the shared hosting account, I am having all sorts of problems. In order to troubleshoot, I attached logging to various stages of this script to track when it starts, how it progresses, and when each step completes, etc. All of this is being logged to a MySQL database.
Problem #1: If I run the script ad-hoc via an HTTP request, I find that it will run for a couple minutes, and then the script starts again (so there are now two instance apparently running). Wait another couple minutes, and a third one will start, etc..... Here is an example when I triggered the script to run at 10:09pm via an HTTP request.
Needless to say, I DO NOT run it via an HTTP request because it only serves to get me in trouble with my web hosting provider :)
Problem #2: When the script runs on the server, triggered via a cron job, it is failing to complete. I have taken the production copy of the database and taken it locally along with the XML files, it runs fine. So it should not be a problem with bad data exposing bad code. My observation is - the script nearly runs for the exact same amount of time - before aborts, or is terminated, or whatever. The last record updated is generally timestamped around 4 minutes and 30 seconds or so (if memory serves) after the script is triggered. The SKU list is constantly changing so the record that it ends on differs, but the the time of the last update is nearly the same each time. Nothing is being logged in the error logs. I monitored server resources via SSH top command and there is nothing out of the ordinary. CPU usage is in check and memory used does not go up.
I have a shared hosting account through Bluehost. My thoughts were that perhaps it was a script max execution time issue. I extended the max execution time in the script itself and via php.ini. Made no difference.
So I guess what I am looking for is some fresh ideas of where to go next. What questions should I be asking my hosting company so they can help me get to the bottom of this. They are only somewhat helpful to say the least. Could it be some limitation on my hosting account? Triggering some sort of automatic monitor that is killing the script? What types of Apache settings could be problematic for a script of this nature? PHP.ini settings? Absolutely any input you can provide would be helpful.
And why, when triggered via HTTP, would it keep spinning up new instances? I guess I could live w/o running it manually, and only run it via a cron job, but that isn't working either. So .... interested in hearing the communities thoughts on this. Thanks!

Postgres won't listen on Docker host IP address after reboot until Postgres is restarted
I have a brand-new Debian 9 with Docker 18.09 (installed from the official Docker repository) and Postgres 9.6. I've edited
/etc/postgresql/9.6/main/postgresql.confto set the
listen_addresses = '127.0.0.1,172.17.0.1'
After making that change and restarting Postgres, my Docker containers can connect to Postgres at 172.17.0.1 without any problems. The issue comes when I restart the entire OS, Postgres will not listen on 172.17.0.1 until I restart Postgres itself. I've swapped the order of the addresses in
postgresql.confto no avail, running
psqlsays it's listening on both the ports I've specified, but
sudo netstat -nashows it listening only at 127.0.0.1:
$ sudo netstat -na Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN tcp6 0 0 :::22 :::* LISTEN
A restart of Postgres (
systemctl restart postgres), and now it's also listening on 172.17.0.1:
$ sudo netstat -na Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN tcp 0 0 172.17.0.1:5432 0.0.0.0:* LISTEN tcp6 0 0 :::22 :::* LISTEN
This means that my Docker containers that start on boot that connect to Postgres fail to start up automatically because they get a "Connection refused" error.
Jenkins job build error | Trying to build docker image | Jenkins and Docker both are installed in Windows 7
I have installed docker toolbox and Jenkins on my windows 7 laptop (virtualization enabled), and I'm trying to build a Jenkins job for creating and deploying an Angular image.

FYI, I have added "C:\Program Files\Docker Toolbox;C:\Windows\System32" in the path varialble but still the error persist.

ML.NET in Unity
I cannot figure out how to use ML.NET in unity. The ML examples are all done in Visual Studio projects that target 64 bit processors and are of type .NET Core.
As unity does not support that I am guessing my best bet is to try building a .dll - api project and importing it into Unity:
I have tried building an xxxx.dll api(.net core 2.0 class library) and copied it into /Assets/plugins folder, but when typing a 'using xxxx;' statement it is as though it was not there. I have also tried building a framework api but ML support starts at framework version 4.6.1, and if I build that version, Unity does not recognise the xxxx.dll either(unity targets framework 3.5). The same goes for the .net standard api build.
So I guess my question is: How can I use ML.NET in unity?
Axios React Browser Compatibility (Cross-Browser and Older Versions)
Is there any table, page or way of knowing what browser versions of Safari,Chrome,IE,Edge and Firefox are supported by Axios?
I've been searching for hours and i can't seem to find anything related. Official guidelines are vague (It only states that it supports the latest versions of each browser which is not very helpful)
Compatibility of commons FileUpload 1.3.3 with Struts1
My project is working on Struts-1 framework (using struts tags-html-el tag) with FileUpload version 1.0. We want to replace old FileUpload (v1.0) in the project with new one (v1.3.3). I simply replaced the old jar with the new one and after successful build, the functionality didn't work.
So, want to know is there any code changes I need to make to run 1.3.3 with my old code, or since all the other jars are old so this new one will not work? Any help would be appreciated.
