Linking libstdc++ statically
Christopher Baus writes about his problems linking libstdc++ statically. Yes, making C++ binaries that will work properly in different Linux distributions is somewhat painful. The problem is not so much linking libstdc++ statically – it is just a library, after all – but the runtime support required by C++ code in general, to enable features like RTTI and exception handling.

The runtime support code used by different parts of a C++ application needs to be compatible. If one part of the program needs to dynamic_cast or catch objects provided by another, both parts must agree on certain implementation details: how to find vtables, how to unwind the stack, and so on.

For C++ and a few other GCC-supported languages with similar features, such details are specified by a C++ ABI. Whenever the ABI used by GCC changes you'll end up with incompatible libraries produced by the different GCC versions. The same is true for plain C, but the C ABI is much simpler and has been around a lot lon

Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}

About History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:

Workarounds for Netflix and the blocking of Hurricane Electric IPv6 tunnels

The dreaded "You seem to be using an unblocker or proxy." error message. Cool story bro.

This gist was essentially created out of my own rant about Netflix being hostile to IPv6 tunnel services since June 2016. You are welcome to read my opinion on the matter, this is the more technical side to the issue and how to combat it within your own network.

Since I wrote this, various GitHub users have contributed their thoughts and ideas which has been incorporated into this gist. Thank you to everyone who have contributed their own methods and implementations.

The problem

Netflix now treats IPv6 tunnel brokers (such as Hurricane Electric) as proxy servers. A while ago it became apparent to users and Netflix that somewhat by accident, IPv6 tunnel users were being served content outside of their geolocation because of the way Netflix was identifyi
