fsck-ing your Git objects by default

Yo developers (git interactive users), check if you are fsck-ing your objects on transfer:

git config --null --get transfer.fsckobjects
git config --null --get fetch.fsckobjects

If that is null or false, then …​ set it to true:

git config --global transfer.fsckobjects true

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
