When git reset –hard doesn’t work


Sometimes things go wrong and we want to start from scratch. Provided you’re using Git as your version control system, it’s highly probable you’re a friend of git reset --hard.
However, I’ve found cases when git reset –hard doesn’t work. Things like clean or -f parameter doesn’t work either.
I did however found out, that sometimes on Windows machines, line endings like to live their own lives and switch randomly between CRLF and LF.
I found a solution I want to share with you. However, I do not see myself as a Git pro, so if you found out other one for such issue, let me know! 😇

First thought

First thought would be to just stop git from doing so.
Generally in either your global or repository config you have section called core. An entry called autocrlf resides there and is often responsible for behavior mentioned above.
Quick fix for this would be to just set the flag to false by calling in your repo (or adding --global after config for global scope):

If config change fails

Been here, seen that. It seems that sometimes there is an issue with line endings that is also driven by .gitattributes file, even if it is not present in repository!
A fix for this is to remove (non-exisiting) .gitattributes, then stage the change and then reset changes like you used to do:

Note: git add -A is necessary here and it can’t be changed to git add * because it won’t stage file deletion that we did with rm command.

If you do have .gitattributes included in your repository, you might want to actually tweak it with proper line endings per extension defined instead. 🔨

Setup .NET Core on Ubuntu

MS <3 Linux

.NET Core 1.0 is here and it’s a great, great opportunity to start playing with it not only on Windows platform but also on Linux. Today I will show you not only how to run .NET Core but how to setup whole developer environment for developing .NET.
Since one of Microsoft main goals was multiplatform support, let’s take a quick look on how-to setup .NET Core on Ubuntu.

Why Ubuntu? Well.. it’s popular and easy. Also Microsoft used it as a platform of choice for their Bash and Docker support for Windows so decision seemed quite straightforward to me. We’ll be working here on Ubuntu 14.04 LTS as it’s the most widespread version now.

You can also try other platforms as I did, especially Red Hat Enterprise which is totally free on http://developers.redhat.com/ for developers. They also fully support .NET on RHEL and are part of .NET Foundation. Quite rock-solid backed, isn’t it?

Getting .NET Core on Ubuntu

Well, that’s probably the easiest part as it well documented (for now) at Microsoft .NET Core site.
As stated in docs, execute on after another in Terminal to install the framework:

Let’s try if that worked. Type dotnet in Terminal and see if command is recognized:

Setup .NET Core on Ubuntu

Alrighty. Working as intended!

Enter Yeoman – our beloved code scaffolder

Since what plain .NET Core framework offers us in terms of scaffolding is quite minimalist (we can only dotnet new to create empty project), we must turn ourselves to other tools. One of the most popular (if not the most popular) scaffolder is Yeoman. If you’re Linux fan, you already know it very well from other projects.
In order to install Yeoman we’d need two dependencies – Node.js and npm.
Since Ubuntu 14.04 has too old version of Node.js to run Yeoman, we’d need to update it. That’s the part where I’ve struggled a little, as most of generic Ubuntu approaches I knew did not work out. I’m not Ubuntu pro so I’ve turned myself to internet and browsed for working solution.

This one seems to be always working and I’ve read that it’s generally THE recommended way of updating/installing Node.js:

If update was successful, typing node –version should return version 5.X, where X is the latest version of 5th release.
As we now have proper Node.js version, let’s proceed to Yeoman installation.

Let’s install Yeoman itself with command:

Then, we’d need generator for .NET Core templates:

If everything went smoothly, we should see Yeoman welcoming us in generator when we run yo aspnet in Terminal:


Optional step – Visual Studio Code

That might be a NO-NO solution for wide range of vim or Sublime Text fans out there, but if you’re willing to check what Microsoft has to offer in lightweight, modular code editors, give VS Code a try.
Since VS Code is generally available through http://code.visualstudio.com/ site, there is no easy way to get it through terminal.

I’ve managed to get it using wget and downloading .deb package from Microsoft download site to Downloads folder and then installing it via dpkg:

No idea if the ?LinkID=760868 won’t change, will keep in touch with Microsoft to clarify that.

But, but… I want to automate!

Since we’re now in raging era of DevOps, we all want to automate. And that’s great! We should whenever we can.
We can easily pack all the lines above into bash .sh file and run it with preceding sudo to get elevated privileges.

Not enough? It’s fine as I’ve already prepare such script in my ubuntu-helpers repository on GitHub.
Just clone the repo to your Linux machine:

Then just run bash script with:
