Can we install a ROR web app developed in Windows platform to Linux machine? - linux

We have developed a Ruby on Rails application in Windows 7. Now we want to try installing it on a Linux machine and see if it can work.
What all points should I consider here?
Can we directly deploy the code in Linux? and Should i consider some gems being specific to windows?( I remember using win32ole gem for interacting with excels) Linux is completely new to me. Any help is appreciated.
Ruby version - 1.9.3p327
Rails - 3.2.9
Database - MySQL

How to run Gnome desktop on Ubuntu 20.04 in cloud

After doing a Google search for running a Gnome desktop or just desktop (found Xfce4 info...) on a cloud instance, I found some guides at Digital Ocean, for example:
Install and Configure VNC on Ubuntu 20.04LTS
The problem is, that doesn't help me set up a desktop that can run Visual Studio Code or other apps. vscode fails to run, and so does the Atom text editor. They seem to need something like the Gnome Desktop to run, which I can't start using the information in that link. I can't just replace xfce4 with gnome-session and get it to work.
Am I missing something? I have installed gnome desktop and vnc server.
I hadn't installed all the packages I needed. Some were missing in the various guides I read.
So I went here:
Installing and configuring Ubuntu Desktop for Google Cloud Platform
... and it worked perfectly.

How create build .net with MSBuild in Jenkins on Server Linux

I tried to configure jenkins that is mounted on a server with linux, is it possible to install msbuild.exe to compile a .NET application? or is it necessary for Jenkins to be on a windows server?
The .NET Core SDK can be installed on Linux and comes with a tool called dotnet which can work pretty similar to MSBuild when you run it as dotnet build.
It depends on what purpose. If it is to study, I recommend installing Jenkins on a Windows Server, then installing the .Net Framework SDK that you want to use.
If it is a productive environment, I recommend installing Jenkins Master on Linux Server and a Slave on Windows Server, then installing the .Net Framework SDK that you want to use. So you do not overload the Jenkins as you compile.
If you look at the version of the .Net Framework SDK, because if any font needs something specific, you will have to install the Microsoft Windows SDK.
For configuration see this link.

Rails 5.2 credentials throwing error

I am using Rails 5.2.0 and Ruby 2.5.1p57.
I have introduced Rails ActiveStorage to my Rails application. I am able to upload/download file to/from S3 if I use AWS key-secret directly.
When I am running below command
EDITOR="subl --wait" rails credentials:edit
1: from /home/nishant/.rvm/gems/ruby-2.5.1#creative_automation/gems/activesupport-5.2.0/lib/active_support/message_encryptor.rb:157:in decrypt_and_verify'
/home/nishant/.rvm/gems/ruby-2.5.1#creative_automation/gems/activesupport-5.2.0/lib/active_support/message_encryptor.rb:190:in_decrypt': ActiveSupport::MessageEncryptor::InvalidMessage (ActiveSupport::MessageEncryptor::InvalidMessage)
This is not my ubuntu system or gemset specific issue as I tried the same thing on other machine but still it is not working.
Thanks in advance.

TideSDK app on Mac

I developed an app via TideSDK on OSX. I have a .app and It is working on OSX. However, you know it cannot work on linux or windows. I want to run my app on linux or windows. How can I do that?
In short, you package for each platform. As you are aware mac apps do not run on Windows and it is the same with TideSDK since you are creating something native for each platform.
TideSDK must be installed on each platform to create an executable and bundle for it.
To generate an installer for each system, you need to run commands on each system (windows / linux 32bit / linux 64bit) using tidebuilder.py on the command line.
We will have more to speak about concerning packaging quite soon that will make the task of building and distributing your apps easier. Stay tuned for updates !!

Meteor support developing on Windows

Does Meteor support developing on Windows? I did not see any downloads or mention of Windows in the docs.
The "Quick Start" assumes you are on *Nix OS.
Meteor 1.1+: official Windows support launched on https://win.meteor.com/
Meteor 1.0+: there is an official Windows preview.
Meteor 0.8 and older: see http://win.meteor.com/
Proof, Meteor running on Windows.
Edit: See Tom's answer.
Old answer below.
No, this is not yet supported on windows. If you try to install in you will receive the following error:
Sorry, this OS is not supported yet.
As a workaround you can run a linux box in a VM and use that as a server to run meteor but still do all development from within windows. I've done this using VirtualBox to run Ubuntu with no GUI. Here's the steps:
Install VirtualBox
Grab Ubuntu ISO
Setup Ubuntu VM using VirtualBox (just follow the wizard steps)
Install samba on VM to enable file access from windows. This article was a great help.
Install ssh using Ubuntu Software Center. This was helpful.
Shutdown VM and run from a DOS prompt using vboxheadless -startvm "VM Name"
You can then use a ssh client (I'm using cygwin) to connect to the box to run commands e.g. ssh user#box_ip_address
Can browse and edit files using windows file share e.g. \\box_ip_address\share
Can run meteor apps within local browser, just replace the localhost in the address that meteor assigns with the ip address of the box.
I just tried to install it with curl on Windows 7, and got:
Sorry, this OS is not supported yet.
A substantial update as the existing answers to this question are very out of date.
Official Windows support can be found at https://github.com/meteor/meteor/wiki/Preview-of-Meteor-on-Windows
Unofficial Windows support for Meteor can be found on http://win.meteor.com/
There are 3 solutions outlined on win.meteor.com, one native MSI installer, and 2 virtualized solutions based on Vagrant:
1) MSI Installer:
Stephen Darnell has picked up where Tom Wijsman graciously left off.
This solution is the most straight forward way to get Meteor running
on Windows with an MSI Installer provided. There are some trade-offs
because this is a fork and can lag behind the latest version as
Stephen can update to and test the latest version.
2) Vagrant Shell Provisioning
Gabriel Pugliese has posted a guide for how to provision Meteor on
Linux with Vagrant's Shell Provisioning. These may be more accessible
to users familier with Linux and Shell scripts. This solution is
easier to tweak through the straight forward shell commands than the
Chef alternative.
3) Vagrant Chef Provisioning
Matthew Sullivan is maintaining a set of Vagrant files, Chef cookbook,
and guide for provisioning Meteor on Linux with Vagrant. This Chef
solution is a slightly more automated and configurable than the shell
solution, however likely not as simple to tweak beyond the provided
configuration parameters as the Shell solution.
GitHub Repos and details can be found on win.meteor.com. The three authors are very responsive on the Meteor-talk Google Group.
A bit of history:
Unofficial Windows support for Meteor was started by Tom Wijsman, and was supported by Tom until 0.5.9. Versions 0.6.0 and later are by Stephen Darnell, Gabriel Pugliese, and Matt Sullivan.
I do not see Nitrous.io mentioned here.
I am using Nitrous.io together with Nitrous Desktop, which allows you to use your favourite text editor (in my case, Sublime Text).
There is a quick tutorial here and Discover Meteor also deals with this in chapter 2.
It sounds like Windows is not supported yet. If you want to play with it, I would suggest grabbing VirtualBox and installing your favorite flavor of Linux on it.
I downloaded the above .msi installer and installed to c:\Meteor
Add the c:\Meteor directory you just made to your PATH environment variable.
Run the following command: npm install Meteor-Test-Installer
Add the C:\Meteor\bin\node_modules\npm\bin directory you just made to your PATH environment variable.

Update the MondoDB folder with the latest mogodb files from the mongodb site.
I've found that new coders who are also new to Meteor might have installed it correctly, but are having trouble figuring out how to open and run it. So I'll just address that issue in this post.
1) I assume you went here: http://win.meteor.com/ and downloaded the MSI installer
2) I assume you then created a newapp in meteor and then ran meteor
3) If steps 1 & 2 are complete, you should see this in your command line:
Initializing mongo database... this may take a moment.
=> Meteor server running on: http://localhost:3000/
4) Open Chrome and type in the local host address: http://localhost:3000/
5) Open your newapp folder - should be located in your Meteor folder wherever its installed on your hard drive
6) Open your newapp.html, newapp.css, and newapp.js files in your favorite editor (like Sublime Text 2)
7) Begin editing these files as you like and watch your page automatically update, as Meteor is designed to do.
Voila!! You're building with Meteor. Enjoy!!
As of two days ago, a preview version is available here:
https://github.com/meteor/meteor/wiki/Preview-of-Meteor-on-Windows
Recent check of their site and checking their FAQ, you'll find the Meteor Development Roadmap. They host it on Trello and after the 1.0 launch, you'll see "Official Windows Support." So, it's on the map - now we wait!
