My first successfull LibreOffice build 4.0

This is my first successfull LibO build from source  on my Debian sid laptop (it took a while to get all set and waiting for the copile to finish)

After all finished i started it

with make dev-install

/home/mariuz/work/libo/solver/unxlngx6.pro/installation/opt/program/soffice &

Firebird 2.5.2 stable for all Ubuntu releases is uploaded into ppa

I recommend Ubuntu 12.04 LTS or 14.04 LTS
http://www.firebirdnews.org/?p=7981

The other are builded OK but with some modifications to the Debian scripts

I give some examples of modifications for Lucid and Hardy in the

debian scripts area
http://jimicompot.blogspot.ro/2012/11/firebird-252-for-ubuntu-lucid-is.html

http://jimicompot.blogspot.ro/2012/11/firebird-252-on-ubuntu-hardy.html

Hardy it will be EOL soon in April so for the next Firebird release it

will be skipped

(it doesn't support the quilt 3.0 format and and is hardest to build for )

The older the Distro the harder it it is to build the software for it .

Lazarus FreePascal IDE on Raspberry PI

I have installed the version from debian respository

sudo apt-get install lazarus-ide fpc

The install and developing process is the same like on any Debian machine
I have started the ide over the ssh

ssh -X pi@192.168.1.104
lazarus-ide

I have the Firebird components i can start doing Database apps like on any desktop

Using Lazarus IDE with Firebird in Ubuntu and Debian

Install the ide

sudo apt-get install lazarus-ide

Start the ide from the console/terminal

 lazarus-ide &

If everything went well you'll see a new tab called SQLdb. This tab will contain two components a TSQLConnection and a TSQLQuery.








SQLdb tab also contains a component TIBConnection that you can place it on the form


We will connect to /var/lib/firebird/2.5/data/employee.fdb
On the form put an TIBConnection, TSQLTransaction,TSQLQuery,TDatasource and an TDBGrid









TIBConnection is configured to have DatabaseName=/var/lib/firebird/2.5/data/employee.fdb
Password=masterkey
Username=sysdba
and Transaction=SQLTransaction1
You can put it to be Connected = True




Then configure SQLTransaction1
to use

Database=IBConnection1
Active =True;




Configure TSQLQuery this way

Database:IBConnection1
SQL=select * from employee;
Active = True;








Configure TDatasource
DataSet=SQLQuery1



Configure TDBGrid

DataSource = DataSource1




Next you can put an button and make them active from run time


procedure TForm1.Button1Click(Sender: TObject);
begin
SQLQuery1.Active:=true;
end;

Later i will try firebird c api examples

cd /usr/share/doc/firebird2.5-common-doc/examples/api 
cp *.gz ~/
chown pi.pi *.gz
cd ~
gunzip *.gz
gcc -L/usr/lib -lfbclient -I/usr/share/doc/firebird2.5-common-doc/examples/include/ api1.c
ISC_USER=SYSDBA ISC_PASSWORD=masterkey ./a.out /tmp/new.fdb
Created database '/tmp/new.fdb'.

Successfully accessed the newly created database.

So all it works as it should without errors and at the speed of pentium 2 like system or even faster I love the small server and i can leave it on 24x7 without the need to think too much for the energy costs
Next i have tested the firebird python driver fdb

sudo apt-get install python-pip
 

pip install fdb
cat test.py
con = fdb.connect(dsn='/var/lib/firebird/2.5/data/employee.fdb', user='sysdba', password='masterkey')

cur = con.cursor()
SELECT = "select * from employee"



# 2. Equivalently using fetchall():
# This is potentially dangerous if result set is huge, as the whole result set is first materialized
# as list and then used for iteration.
cur.execute(SELECT)
for row in cur.fetchall():
    print 'ID:%d Name %s.' % (row[0], row[1])


python test.py
....
ID:141 Name Pierre.
ID:144 Name John.
ID:145 Name Mark.

Next on my testing list is compiling the node.js (doing it rightnow) and the pure JavaScript Firebird driver with an express demo Update : compiling node is done here are my results

TopDAY: Drupal Meetup in Târgu Mureș

Great PHP local event will take place in Târgu Mureș, in November 8: TopDAY - Drupal Meetup. The event is focusing on short presentations about Drupal and is supported by Reea

Upgrading from ubuntu 12.10 to debian sid

A good idea is to install a light desktop manager like lxdm or xfce so at least you have a DM in case
gnome will not work out

Install debian keyring http://packages.debian.org/sid/all/debian-archive-keyring/download


modify /etc/apt/sources.list
delete all the lines and
add these ones 

deb  http://http.debian.net/debian/ sid main contrib non-free
deb-src  http://http.debian.net/debian/ sid main contrib non-fre


apt-get update
apt-get -f -o Dpkg::Options::="--force-overwrite" upgrade


there will be a lot of issues and it might bring your  machine unbootable
So be prepared with a testing debian stick or cd

Make a list with packages removed by the dist-upgrade
in my case i have noticed that network manager will be removed

apt-get -f -o Dpkg::Options::="--force-overwrite" dist-upgrade

From the removed packaged i picked the critical ones that i know i need and i download them before to start the upgrade so i can install them with dpkg -i


Here is my list that i needed on my system (that i know that are critical to me and to make the system functional)
apt-get  install --download-only network-manager network-manager-gnome lxde modemmanager ssh openssh-server alsa-utils anacron at


Here are some of the issues that could happen while upgrading the machine there are many dpkg-new files in the /etc/init.d/ folder so here are some tips bellow

Init scripts and networking system
Get rid of upstart first. I had problems with sysv-rc and needed to force reconfiguration. Some init scripts were installed with "dpkg-new" in the name, I had to rename them. As with X, I tried few solutions, this is distilled but stil redundant version:

dpkg-reconfigure sysv-rc
cd /etc/init.d
mv acpid.dpkg-new acpid
mv anacron.dpkg-new anacron
mv atd.dpkg-new atd
mv cron.dpkg-new cron
mv dbus.dpkg-new dbus
mv module-init-tools.dpkg-new module-init-tools
mv procps.dpkg-new procps
mv rsyslog.dpkg-new rsyslog
mv udev-mtab udev
apt-get --reinstall install base-files ifupdown initscripts netbase sysv-rc sysvinit sysvinit-utils
