s3git
git for Cloud Storage. Create distributed, decentralized and versioned repositories that scale infinitely to 100s of millions of files and PBs of storage. Huge repos can be cloned on your local SSD for making changes, committing and pushing back. Oh yeah, and it dedupes too due to BLAKE2 Tree hashing. http://s3git.org

GitHub now supports "squash on merge"
yay.

On the other hand -- http://www.thecaucus.net/#/content/caucus/tech_blog/516 is a good explanation of why not to adopt it. Pity GitHub haven't made it a per-review option...

git integrity - Google Groups
It seems git's default behavior in many situations is -- despite communicating objectID by content-addressable hashes which should be sufficient to assure some integrity -- it may not actually bother to *check* them.  Yes, even when receiving objects from other repos.  So, enabling these configuration parameters may "slow down" your git operations.  The return is actually noticing if someone ships you a bogus object.  Everyone should enable these.

OSTree
"git for operating system binaries".

OSTree is a tool for managing bootable, immutable, versioned filesystem trees. It is not a package system; nor is it a tool for managing full disk images. Instead, it sits between those levels, offering a blend of the advantages (and disadvantages) of both.

You can use any build system you like to place content into it on a build server, then export an OSTree repository via static HTTP. On each client system, "ostree admin upgrade" can incrementally replicate that content, creating a new root for the next reboot. This provides fully atomic upgrades. Any changes made to /etc are propagated forwards, and all local state in /var is shared.

A key goal of the project is to complement existing package systems like RPM and Debian packages, and help further their evolution. In particular for example, RPM-OSTree (linked below) has as a goal a hybrid tree/package model, where you replicate a base tree via OSTree, and then add packages on top.

Why your company shouldn’t use Git submodules
'It is not uncommon at all when working on any kind of larger-scale project with Git to find yourself wanting to share code between multiple different repositories – whether it be some core system among multiple different products built on top of that system, or perhaps a shared utility library between projects. At first glance, Git submodules seem to be the perfect answer for this: they come built-in with Git, they act like miniature repositories (so people are already familiar with how to change them), et cetera. They even support pointing at specific versions of the shared code, so if one project doesn’t want to deal with integrating the “latest and greatest” version, it doesn’t have to. It’s after you’ve actually worked with submodules for a while that you start to notice just how half-baked Git’s submodules system really is.'

Docker: Git for deployment
Docker is to deployment as Git is to development.

Developers are able to leverage Git's performance and flexibility when building applications. Git encourages experiments and doesn't punish you when things go wrong: start your experiments in a branch, if things fall down, just git rebase or git reset. It's easy to start a branch and fast to push it.

Docker encourages experimentation for operations. Containers start quickly. Building images is a snap. Using another images as a base image is easy. Deploying whole images is fast, and last but not least, it's not painful to rollback.

Fast + flexible = deployments are about to become a lot more enjoyable.

KDE's brush with git repository corruption: post-mortem
a barely-averted disaster... phew.

while we planned for the case of the server losing a disk or entirely biting the dust, or the total loss of the VM’s filesystem, we didn’t plan for the case of filesystem corruption, and the way the corruption affected our mirroring system triggered some very unforeseen and pathological conditions. [...] the corruption was perfectly mirrored... or rather, due to its nature, imperfectly mirrored. And all data on the anongit [mirrors] was lost.

One risk demonstrated: by trusting in mirroring, rather than a schedule of snapshot backups covering a wide time range, they nearly had a major outage. Silent data corruption, and code bugs, happen -- backups protect against this, but RAID, replication, and mirrors do not.

Another risk: they didn't have a rate limit on project-deletion, which resulted in the "anongit" mirrors deleting their (safe) data copies in response to the upstream corruption. Rate limiting to sanity-check automated changes is vital. What they should have had in place was described by the fix: 'If a new projects file is generated and is more than 1% different than the previous file, the previous file is kept intact (at 1500 repositories, that means 15 repositories would have to be created or deleted in the span of three minutes, which is extremely unlikely).'

GitHub Archive
a project to record the public GitHub timeline, archive it, and make it easily accessible for further analysis. GitHub provides 18 event types, which range from new commits and fork events, to opening new tickets, commenting, and adding members to a project. The activity is aggregated in hourly [gzipped JSON] archives, which you can access with any HTTP client.

Large file management with git-annex
'uses Git to manage files that are larger than Git can easily handle—without checking them into the repository. But git-annex provides ways to track those files using much of the same infrastructure as Git, so that moving or deleting those files can all be tracked in much the same way as committed files. In addition, git-annex allows for branches and distributed clones of its trees.' I may investigate using this to sync my MP3s instead of SVN

Gerrit, Git and Jenkins
This is the future of code review. Commit directly from your git checkout to the Gerrit code-review system; change is immediately web-visible and enters the review workflow; at the same time, Jenkins checks out the proposed change and runs the test suite; once it's approved, it automatically gets checked in. Brilliant!
