CommandLineTools is outdated. The below should fix it.

    xcode-select --install

I had to do the following to resolve:


    xcode-select --install

    sudo xcode-select -switch /Library/Developer/CommandLineTools

Since I had just updated Xcode (using the AppStore) I had to open Xcode and let the installer finish some configuration work before Visual Studio for Mac would successfully compile my Android application again. 

I thought this was weird because my solution did not include any projects targeting iOS. The solution contained just a few .NET Core library projects and an Android APK.

I also had to run the &#39;xcode-select --install&#39; command.

You can simply go to Xcode Preferences &gt; Locations &gt; Command Line Tools &gt; Select latest Xcode version

I&#39;ve created a server-side react app, where it would return html as shown below:

    const html = renderToString(&lt;App /&gt;);
    &lt;html&gt;

        &lt;meta name=&quot;viewport&quot; content=&quot;width=device-width, initial-scale=1.0, maximum-scale=1.0&quot;&gt;

I read a lot of people have been using `react-helmet` to manage the content in head. I&#39;m wondering what&#39;s the benefit of using it, when I can just directly include as shown above.


What is the purpose of react-helmet?

Just started out using self hosted GitLab... it looks like it&#39;s going to be really useful moving towards a DevOps workflow.

Anyway, after migrating about 20 local Git repositories to the new GitLab server, neatly arranged into 4 groups. I then noticed you can actually have sub-groups within the groups. This would help organisation even further, but I&#39;m struggling to work out how to move the existing projects I&#39;ve spent a day importing and configuring into a newly created sub-group. Sure I could just create a new project and copy the files over and commit them into the new project, and spend the time reconfiguring the project.

Is there an easy way of moving the existing configured Project from the group into the new subgroup?

I am trying to understand the difference between

    git push --force

and

    git push --force-with-lease

My guess is that the latter only pushes to the remote *if the remote has commits that the local branch doesn&#39;t have*?

git push --force-with-lease vs. --force

I have a Visual Studio solution with multiple projects, each project is an individual microservice. It is very convenient to the development team to have all the services in the same solution, and git repo, as services can call each other.

    Master.sln - SubFolderA - MicroserviceA.sln
               - SubFolderB - MicroserviceB.sln
               - SubFolderC - MicroserviceC.sln

I would, however, like to independently build/release the individual microservices in Azure DevOps when they change, so if ServiceA is the only service to change, then ServiceA is the only service built and deployed. 

To this end I created a new build pipeline definition with &quot;Path filters&quot; set to trigger the build when the contents of a microservice folder change (so one path filter added per microservice to monitor).

My problem here is that when a build is triggered (based on a change to SubFolderA e.g.) I have no way to tell the build definition to only build the .sln file in SubFolderA.

I could create a separate build definition for each microservice and trigger each build on separate subfolders, but this would come at significant overhead, i.e. I would need to maintain 15 separate build definitions (same again for each branch I build), and the storage required on our self host build agent would now be NumberOfService x NumberOfBranchesBeingBuild x SizeOfRepo.

Is there a way to use a single Build Definition with git &quot;Path filters&quot; and multiple paths defined, which in turn kicks off multiple build instances and feeds the value of the path that triggered the build into the build definition and so telling the build instance which .sln file to build?

I hope that makes sense!

Is there a way to change branch name in Azure DevOps. As shown in SS i have named my branch as Developer branch, now i want to change it to a specific request-id.
Is this possible.

Starting with v1.11 Go added support for modules. Commands

    go mod init &lt;package name&gt;
    go build

would generate ``go.mod`` and ``go.sum`` files that contain all found versions for the package dependencies. 

If a module does not have any releases, the latest commit of that module is used. If a module does have releases, the latest one is picked as a dependency.

However sometimes I would need functionality that is not in a published release yet, but from a commit made after that release. How do I set ``go.mod`` to point not to a release of a module, but to a specific commit in the module&#39;s repository?

It looks like I can do it by hand in go.mod with


    module /my/module
    
    require (
    ...
    github.com/someone/some_module v0.0.0-20181121201909-af044c0995fe
    ...
    )

where `v0.0.0` does not correspond to the last published release tag, ``20181121201909`` would be a commit timestamp and ``af044c0995fe`` would be the commit hash? Should such information to be found and entered by hand, or there is a better way?

I&#39;ve been using Visual Studio Code since it was in beta and one of the features I like best about it is the integrated terminal for using the Angular CLI in app. I&#39;ve had it working fine since I had the laptop, but I re-installed Windows 10 over the Xmas break and obviously as a result had to re-install Visual Studio Code. 

Since then I&#39;ve had issues with the Terminal, it&#39;s blank until you hit return, at which point you see the path, but not the usual copyright notice you should get from the Windows Command Line.

Before hitting return:
[![VS code Terminal 1][1]][1]

After hitting return:
[![VS Code Terminal 2][2]][2]

And this is what I was expecting directly from the Windows 10 Command Line:
[![Windows Terminal][3]][3]

So far I&#39;ve tried the following:

 - The usual Windows shut down / restart
 - Re-installing VS Code (even changed from regular to insiders)
 - Changing the default Command Line Shell from CMD to Powershell and
   back again
 - Adding a new Command Line Shell

Is there anything else I can try? Has anyone else encountered the same issue?

Visual Studio Code - Terminal Blank Screen

After updating miniconda3, whenever I open a terminal it shows &quot;(base)&quot; in front of my username and host.

In this answer post https://askubuntu.com/a/1113206/315699 it was suggested to use

    conda config --set changeps1 False

To remove it.

But that would remove the indication for any conda environment. I would like to remove it only for the base one, so that I can maintain it always active and have access to its python and installed packages without having to always see this (base) taking up space.

I freshly installed `vim` (Vi IMproved 8.1) as a text editor on my MacOS 10.14.5 with Homebrew. Each time that I run vim I get this error message:

It is stopping the simulator from running!
How can I stop it?
