• Create a working copy of the deleted folder’s parent. You can use -N parameter that indicates “No checkout”. This will prevent from actually downloading any code. Run:

svn co -N SVN_PARENT_URL .

• Get a copy of the deleted folder from the revision before the deletion. Run:

svn copy SVN_PARENT_URL/DELETED_FOLDER_NAME@REV DELETED_FOLDER_NAME

• Commit to HEAD. This will actually commit a new revision with the contents of the revision before the deletion. Therefore restoring the “original” folder. Run:

svn commit -m “Restoring” DELETED_FOLDER_NAME

This means:

• you can control as many DBs as JDBC drivers exists out there (MySQL, Oracle, Postgresql, etc, etc.)
• you can run it in Linux, MacOS, Windows, etc, etc.
• it’s free.

Thanks, Jorge!

It is fully cross-platform and generates a single installer. As such, it is an alternative to native solutions such as platform-specific installers and package managers.

IzPack-generated installers only require a Java virtual machine to run.

The second programmer replies, in obvious repulsion:
- “Ugh, you used goto!”

“Neo4j is a graph database. It is an embedded, disk-based, fully transactional Java persistence engine that stores data structured in graphs rather than in tables. A graph (mathematical lingo for a network) is a flexible data structure that allows a more agile and rapid style of development.
[...]
Neo4j has been in commercial development for 8 years and in production for over 5 years. It is a mature and robust graph database[...]
In addition, Neo4j includes the usual database features: ACID transactions, durable persistence, concurrency control, transaction recovery, and everything else you’d expect from an enterprise-strength database.[...]“

mongoDB:

“MongoDB is a high-performance, open source, schema-free document-oriented database.[...]
When we describe MongoDB as “document oriented”, we mean it’s in the class of databases for which the primary storage unit is a collection – possibly structured – of data, most likely as key/value pairs.”

Hypertable:

“Hypertable is an open source project based on published best practices and our own experience in solving large-scale data-intensive tasks. Our goal is to bring the benefits of new levels of both performance and scale to many data-driven businesses who are currently limited by previous-generation platforms.”

http://www.hypertable.org/

Dynamo:

“Unlike a relational database, Dynamo is a distributed storage system. Like a relational database it is stores information to be retrieved, but it does not break the data into tables. Instead all objects are stored and looked up via a key.”

Use the following command to install Subversion and the Apache2 module:

sudo apt-get install subversion libapache2-svn

Create a repository:

Use the following command to create a repository:

sudo svnadmin create /var/svn/new-project/

Add permission to the directory for the Apache user only:

chmod -R 775 /var/svn/new-project

chown -R www-data:www-data /var/svn/new-project

Configure Apache

Open /etc/apache2/mods-available/dav_svn.conf and add a new “virtual directory”:

<location /svn>
DAV svn

SVNParentPath /var/svn

AuthType Basic
AuthName "Subversion Repository"
AuthUserFile /etc/apache2/dav_svn.passwd

AuthzSVNAccessFile /etc/apache2/dav_svn.authz

Require valid-user

</location>

Create the users password file. Use the following command the first time only, the -c parameter will create AND override the file if it exists:

htpasswd2 -c /etc/apache2/dav_svn.passwd username

To add other users or change password use:

htpasswd2 -m /etc/apache2/dav_svn.passwd username

In /etc/apache2/dav_svn.authz, add the users permissions

[/]
me=rw

[new-project:/]
other.user=rw

Finally, restart Apache so that the changes take effect:

apache2ctl restart

For those of you who are unaware of what breadcrumbs do, it is navigation aid used in user interfaces. The term breadcrumbs comes from the trail of breadcrumbs left by Hansel and Gretal in the famous fairytale. It is a method for users to keep track of their locations in programs or documents.

#!/bin/bash
SVNDIR=/var/svn
DATE=`date +%d-%m-%Y`
TARNAME=svn_dump_$DATE.bz2
cd $SVNDIR
rm -f *.svndump
rm -f *.bz2
for repo in $(ls -d */)
do
filename=`basename $repo | cut -d\. -f1`
svnadmin dump $repo > $SVNDIR/$filename.svndump
done
tar -cvz -f $SVNDIR/$TARNAME *.svndump
cp $TARNAME /home/yo/svn_dump


Basically, it iterates thru all my repositories in SVNDIR and dumps them (the back up process itself) with svadmin dump.... After that it tars and compress the *.svndump files in one single file TARNAME and then copies it to its final destination /home/yo/svn_dump from where I grab the tar.bz2 files and burn them in a DVD or whatever.

I also have a cron job as follows:

0 0 * * 7 /home/yo/bin/scripts/svndump.sh >/dev/null 2>&1

which runs the script above once a week.

To restore a svn dump file I have to:
1) Untar the tar.bz2 back up file.
2) With the result I run: svnadmin load /path/to/reponame < filename.svndump
3) Set the correct permissions to the restored repositories. This is needed if you restore the back-up in a different path or computer.

That's pretty much what I do. My source code is safe in several different places (I'm a little bit paranoid, I know...)
