MySQL backup using LVM snapshots...
Snapper is a tool that takes MySQL database snapshots.
The only snapshot method supported by Snapper is LVM snapshots.
Using snapshots to backup a MySQL database is an alternative to “online” or “hot” backup.
Snapshots are created by locking the database during the snapshot creation to ensure consistency of the backed-up data. Then the backup is performed from the snapshot without impacting the database.

Tungsten project... proxy, router, SQL load balancer...
It’s an open source project (GPL) in Java to provide a complete software stack that allows database-level scaling:
- Master/slave replication clustering,
- SQL load balancer,
- SQL router/proxy,
- **Monitoring… **
Globally revolves around MySQL and PostgreSQL, but there is a paid Oracle version.
Implements a database-independent master/slave replication system.
A proxy for MySQL and PostgreSQL clients. The connector converts native protocol queries (MySQL and PostgreSQL protocol) into JDBC queries.
MySQL Forks, MariaDB and Drizzle...
**MySQL is in trouble… It’s forking… **
The acquisition of InnoDB and BerkeleyDB (sleepycat) by Oracle…
Then following the acquisition of MySQL AB by Sun, then by Oracle…
A certain number of former MySQL people left Sun, notably the principal architect “Monty Widenius” and quite a few pillars of the MySQL team…
It seems that all the key developers of the project don’t agree with Sun’s direction and even less with Oracle’s objectives…

Online Backup for InnoDB in open source...
XtraDB is the open source fork of InnoDB… And seems more performant…
By the way, they have redeveloped in open source the “online backup” of InnoDB…
And on top of that, it’s compatible with InnoDB!
Which means we no longer need to pay for Oracle’s proprietary product since InnoDB has become Oracle.
Percona XtraDB is an enhanced version of the InnoDB storage engine, designed to better scale on modern hardware, and including a variety of other features useful in high performance environments. It is fully backwards compatible, and so can be used as a drop-in replacement for standard InnoDB.
Dedibox at 29.99€ is over... snif...
Dedibox, a subsidiary of Iliad, which made a name for itself as the first hosting provider to offer dedicated servers at 29.99 euros (excl. tax), has now discontinued this offer. It now only offers servers at 49.99 euros (excluding tax).
In parallel with this commercial reorganization, Iliad has also carried out an administrative reorganization, merging dedibox with Iliad’s 100%-owned Online business.
By ceasing to offer low-cost servers, Dedibox leaves the way clear for Roubaix-based OVH.

a GNU BSD!!!!! I can't believe it!!!!
actually there are ports of the FreeBSD and NetBSD kernel for full GNU environment!!!
http://www.debian.org/ports/kfreebsd-gnu/
http://www.debian.org/ports/netbsd/index.fr.html
I dreamed of it and it exists!!!!
to test!
FreeBSD too fast for Linux?!
V8 is starting to be quite violent!
- real lightweight threads at last
- an improvement to jails towards even more isolation
- complete virtualization of the network stack, for example jails will be able to have their own firewall, and their own state table… so we’ll be able to do virtual firewalls!!!
- the default integration of the new ULE scheduler, this will boost SMP
- the arrival of Solaris’s dtrace, will allow tracing everything that happens in the kernel and in programs in real time!
- well, they’re removing GCC because of GPL v3… to use LLVM+CLANG… so be it…
- native support for Xen guests in paravirtualized mode
- ZFS is already included but here they’re further extending the scope…
- a big cleanup was done in BSD’s volume manager “vinume” which becomes gvinum 2…
