So what we need is a mysql backup solution, probably a bash script what makes separate files per each db and ignores archive and memory engines of course with possibilities of gzipping.

I googled but I didn’t found what exactly we need, fortunately I found some similar like this one: http://carrotplant.com/en/blog/how-to-dump-all-mysql-databases-into-separate-files and I combine them together.

Finally there are the dump script.

#!/bin/bash

############
# Settings #
############

# mysql parameters
MYSQL_USER="root"
MYSQL_PASSWORD="******"
MYSQLDUMP="/usr/bin/mysqldump"
MYSQL="/usr/bin/mysql"
BACKUP_LOCATION="/var/backups/ervername/mysql/"
BACKUP_SQLDIR=$BACKUP_LOCATION$(date +%Y-%m-%d_%H-%M)
EXCLUDE_DBS="(Database|information_schema|phpmyadmin|mysql)"
EXCLUDE_EGX="(MEMORY|ARCHIVE)"
GZIP_ENABLED=1

# THE SCRIPT #

echo "sophisticated dump of mysql databases"
echo "destination: $BACKUP_SQLDIR"
echo "ignore these databases: $EXCLUDE_DBS"
echo "ignore these engines: $EXCLUDE_EGX"
echo "gzipping: $GZIP_ENABLED"

#returns list of ignired tables
ignoredtables () {
   local IGNORES
   TABLES=`$MYSQL --user=$MYSQL_USER --password=$MYSQL_PASSWORD -e "USE $1; SHOW TABLE STATUS;"  | grep -E $EXCLUDE_EGX | awk '{print $1}'`
   for CURRENT_TB in $TABLES; do
       IGNORES="$IGNORES --ignore-table=$1.$CURRENT_TB"
   done
   echo $IGNORES
}

if [ ! -d "$BACKUP_SQLDIR" ]; then
    echo "make dir: "$BACKUP_SQLDIR
    mkdir -p $BACKUP_SQLDIR
fi

# get a list of databases
DATABASES=`$MYSQL --user=$MYSQL_USER --password=$MYSQL_PASSWORD -e "SHOW DATABASES;" | grep -Ev $EXCLUDE_DBS`

# dump each database in turn
echo "dumping databases..."
TIME_SPENT=`date +%s`
OVERAL_SPENT=`date +%s`
for CURRENT_DB in $DATABASES; do
    echo $CURRENT_DB
    IGNORED_TABLES=`ignoredtables $CURRENT_DB`
    if [ $GZIP_ENABLED == 1 ]; then
        $MYSQLDUMP --force --opt --routines --user=$MYSQL_USER --password=$MYSQL_PASSWORD $IGNORED_TABLES $CURRENT_DB | gzip > "$BACKUP_SQLDIR/$CURRENT_DB.sql.gz"
    else
        $MYSQLDUMP --force --opt --routines --user=$mYSQL_USER --password=$MYSQL_PASSWORD $IGNORED_TABLES $CURRENT_DB > "$BACKUP_SQLDIR/$CURRENT_DB.sql"
    fi
    TIME_SPENT=$((`date +%s` - $TIME_SPENT))
    echo "spent: "$TIME_SPENT"s         overal: "$((`date +%s` - $OVERAL_SPENT))"s"
    TIME_SPENT=`date +%s`
done

# removes previous backup older then 7 days

Balbu is an international online bookstore, wich operates in most of the european countries. The company sells mainly hungarian books for the European and American countries.

The main goal was to create th best possible user experience with the easiest interface in mind. We wanted to create a store where the user doesn’t have too many unuseful informations, but enough to choose what books are in his/her main interests.

The cart and the checkout process is also easy to use, so not just the “internet generation” knows how to use it, what and where to type. The site also have a news section, where the editors can write about the latest articles about the world of books and happenings. Besides the easy to use interface we wanted to have the fastest site possible, so the users with bad connections can use the site too.

The client wanted to achieve a site where elementary and high school students can be informed about the Tantargyhalo competition. The students can compete with each other in literary, crativitie and technique.

   

We started to build to site from scratch, and tried to achieve a fully responsive solution with happy colors and many pictures. The site have a gallery where can the users can see the pictures from the previous years as well as the present year competition. The site have a download menu, where the previous works can be downloaded. The framework we used is WordPress with a custom theme and custom functions. We made the whole concept, design and sitebuild.

At the home page, the Tantargyhalo site have a featured image slider, where the picture appears from the selected post. That means the client have a very simple and user-friendly admin page, so they doesn’t need any knowledge about HTML editing.

We also built a mobile interface with the responsive technique, what means the users can browse the site at tablets and smartphones. Of course, the site can detect the resolution of the device, and if it’s a mobile than the small version automatically appears.

Builder.Shop Mobile is the mobile version of the well-known body builder and fitness shop. As the owner of one of the finest fitness shops in Hungary, the client wanted to give the best possible experience for their users, and of course a very easy to use interface to buy the products.

Builder.Shop Mobile was one of our first mobile project, so we had to make a very large research to get to know the mobile trends, the devices, the resolution and of course the users too. We started to build the site from paper scratch, and we started to use the well known jQuery Mobile.

We had to program a fully working shop first, then start to work with the portable device, where the users have a very small area to use as interactions. The finished project is easy to use, user-friendly and of course both the client and the users like it.
