Testing Firebird 2.5 on Debian experimental

Firebird 2.5 final is now uploaded to debian experimental

Here is my sources.list
cat /etc/apt/sources.list

deb http://ftp.us.debian.org/debian/ unstable main
deb-src http://ftp.us.debian.org/debian/ unstable main
Add:
deb http://ftp.us.debian.org/debian/ experimental main
deb-src http://ftp.us.debian.org/debian/ experimental main

Then:
# apt-get update -t experimental

Then install super-server
# apt-get install -t experimental firebird2.5-super

Or if you want the new superclassic

# apt-get install -t experimental firebird2.5-superclassic


Install examples and flamerobin
apt-get install -t experimental firebird2.5-examples flamerobin

cd /usr/share/doc/firebird2.5-examples/examples/empbuild/
sudo gunzip employee.fdb.gz
sudo chown firebird.firebird employee.fdb
sudo mv employee.fdb /var/lib/firebird/2.5/data/

you can connect to the database with flamerobin



update: you can build the firebird 2.5 package from git

half of chapter 6 from django-book

i'm at half of chapter 6 from django book
to use it with firebird is quite easy and with small changes (only the sql examples needs to be modified in the example is used postgres) but i have added the comments to the book on how to modify an not null to a nullable field (or you can do it from flamerobin)



the rest of the admin area works great




The previous chapters 1-5 modifications for firebird are on this page

for about 2 days i got some strong flu virus and i only sleep and with heavy sweat

Movies to watch ~ Xmass, Porcelain death as santa claus

I love the ones with horror inside so i guess the best movie i saw on Xmass ever
is The Nightmare Before Christmas , next is Bad Santa , Last night i saw one movie where Death was Santa :HOGFATHER (on tvr2) quite impressive
and i didn't expected to see such a good movie on Xmass , maybe because all tv station are playing the same crap over and over each year : home alone 1-2-3 , santa klauss related ones and
the ones with Arnold ... and so on

I recommend instead some good horror movies made for Xmass or for Helloween
http://horror.about.com/od/toppicksandthemelists/tp/Scary-Christmas.htm

For a commedy i guess 2012 could fit the bill
I wonder why the hack didn't put all the people on Himalaya mountains and from where they got all that water 8km high ? do the calculations and you will see that
that volume of water is more than what is found on earth

#kde 4.4 beta safe guide to upgrade on #ubuntu #karmic

kde 4.4 is released here is a way to upgrade and then downgrade to 4.3
in a safe way (and to keep the list of installed packages)


before you upgrade is better to save your list of pachages
dpkg --get-selections > installed-software.log

then you can reinstall qt/kde packages from console if you have
problems with (revert to qt 4.5.x if you want)

Install kde 4.4 and qt 4.6
http://www.kubuntu.org/news/kde-sc-4.4-beta-2


Here is my way to revert on the old packages kde 4.3.x and qt 4.5.x

CTRL-ALT-F1

sudo /etc/init.d/kdm stop

sudo apt-get purge libqtcore4
then i did the steps from above
with
sudo dpkg --set-selections < installed-software.log
sudo dselect
and press I to install all the packages saved

We are not stupid Monty

Reuters reports that Microsoft and SAP and Monty Widenius will be at the meeting on the 10th at the EU Commission, and not a single customer. Oracle has eight customers committed to being there to support Oracle's position. Eben Moglen will also participate.




http://www.groklaw.net/article.php?story=20091208104422384
http://www.groklaw.net/article.php?story=20091021164738392




even IBM is not against this issue , they know who is behind all this attack on Oracle and Open Source in general old friends: Microsoft 


Mysql ..bla bla bla ... Its primary competitor is Microsoft's SQL Server.

That i think hurts more for Microsoft , they can't sell their ms crap .
They wish Mysql to be under BSD license to be assimilated into azzure
like they did with bsd socket libs

generating all flags for skype with #flamerobin and #firebird sql

Here is how to get the original script
wget http://27.org/isocountrylist/iso_country_list.sql

create a new table with this syntax (I have just deleted the "IF NOT EXISTS" from the original table creation script)

http://paste.ubuntu.com/343619/

populate the table with load script from flamerobin
http://paste.ubuntu.com/343617/

the only issue was quoting in firebird , you just need to replace \' type of quoting with "

If you need to use an apostrophe inside a Firebird string, you can “escape” the apostrophe character by preceding it with another apostrophe.

For example, this string will give an error:

'Joe's Emporium'

because the parser encounters the apostrophe and interprets the string as 'Joe' followed by some unknown keywords.

To make this a legal string, double the apostrophe character:

'Joe''s Emporium'

Notice that this is TWO single quotes, not one double-quote.

Run this query in flamerobin to get the iso from table

SELECT a.ISO
FROM COUNTRY a

We need to add (flag:ISO) to the query with the concatenation

SELECT '(Flag:'||a.ISO||')'
FROM COUNTRY a

and do the copy paste in skype :P





Create a procedure that concatenates thouse values

and do a select

SELECT p.SKYPE_COUNTRIES
FROM RETURN_COUNTRIES10 p

and copy paste

result should be like this

Firebird community letter to Monty :we don’t have such worries!

Here is why we sleep so well in the night : because we don't touch the mysql and we don't need it
http://www.firebirdnews.org/?p=3907

I know that Monty is part of new codeplex fundation
so his masters might be related to Microsoft:
New masters new dogfood


Another issue is Maria Fork is a dead end and i see around that nobody is using in the Lamp world
so he needs the Mysql brand back for free , That is smart because the community build it that name in Years and is very hard now to change them from Lamp to Maria (unknown one)

This post is related to Steve's post on computerworld

wxwebkit is amazing and flamerobin future

I was thinking on howto evolve the flamerobin project and i think the next stage (for example on E/R diagraming) would be to adopt the wxwebkit engine for interface rendering , what we do now with wxhtml

Instead of it we will use jquery and paint in the browser canvas (similar like in thunderbird 3.x)
The tree in the left will stay native and the grids , but some parts in the future will be replaced with cool html that can be skinned with css.
Core will stay c++ and parts of the interface will be pure native.

To build wxwebkit on ubuntu/debian was quite easy:
sudo apt-get install gcc g++ flex bison gperf libxml2 libxslt1.1 libxslt1-dev libcurl4-openssl-dev libsqlite3-dev libpng12-dev libjpeg62-dev libpango1.0-dev libgtk2.0-dev subversion

git clone git://gitorious.org/+wxwebkit-developers/webkit/wxwebkit.gitcd wxwebkit/WebKitTools/Scripts
./build-webkit --wx --makeargs="-j2"
cd wxwebkit/WebKitBuild/Debug.master
chmod +x libwxwebkit.so
sudo cp libwxwebkit.so /usr/lib/
./wxBrowser

What is so amazing ?, you can put webkit in edit mode and actually Edit the website (html) !

The sad happy story of snow in Kubuntu Karmic

At first Windows-F3 key (aka Master-F3) didn't do anything

so i searched for a upto date compiz ppa

sudo kate /etc/apt/sources.list.d/compiz.list

deb http://ppa.launchpad.net/compiz/ppa/ubuntu karmic main
deb-src http://ppa.launchpad.net/compiz/ppa/ubuntu karmic main


sudo apt-get update
sudo apt-get dist-upgrade

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 42C24D89

install compiz related packages

sudo apt-get install compiz compizconfig-settings-manager compiz-kde compiz-fusion-plugins-main compiz-fusion-plugins-extra emerald librsvg2-common compiz-fusion-plugins-unsupported


Install fusion-icon
sudo apt-get install fusion-icon

a tray icon to enable compiz and it will disable kwin
and also you can enable Windows decorator to be Emerald not kde4


Select Compiz Configuration:
K menu -> Applications ->Settings -> CompizConfig Settings Manager

and enable Snow Effect




well you could install compiz-dev and compile from source but is 2a.m. and i want to sleep

I have debugged the issues with snow from console with
compiz-manager --replace and with ccsm from another console
ps:
Snow seems to be removed from Karmic and it gave an api missmatch that is why it didn't worked in the first place
Now it's not as simple as it was before but problem is solved

Html2DocBook #python and Firebird in 2 Minutes #html document

I try to convert it (this html document ) to docbook format and

I have installed the html2docbook tool
http://pypi.python.org/pypi/html2docbook/

from python console
from html2docbook import Html2DocBook
h2d = Html2DocBook()
f = open('./fb2min.html', 'r')
x=f.read()
h2d.transform(x)
'<section/>

that is the only tag that is spitted out!
if i do print(x) i get all the content for html
even
_debug=True doesn't work no details or verbose mode


ps: i saw that some things are old on that page i was thinking that is
better to be kept in docbook format and versioned (cvs/git ...)
also i have tried to do some tidy html on it
for the moment we will stick to html format it's easier and anyone can edit it
maybe i will add it to git (docbook is harder to crack)

Found a bug in git-cvsimport so i will use cvs2git

I'm not the only one that found the bug

"Me, I don't trust anything but cvs2git to import a CVS repo. I then use git-cvsimport to keep it up-to-date, but even then, I've seen it omit a couple of commits for no good reason, forcing me to re-import from scratch."

so i will use cvs2git to import all the firebird branches

mkdir firebird2
cd firebird2

rsync -av rsync://firebird.cvs.sourceforge.net/cvsroot/firebird/firebird2 .
rsync -av rsync://firebird.cvs.sourceforge.net/cvsroot/firebird/CVSROOT .

cd ..
svn co --username=guest http://cvs2svn.tigris.org/svn/cvs2svn/trunk
cvs2svn-trunk

# Dump the CVS history in a format ready for git-fast-import (a few hours)
cd cvs2svn-trunk
./cvs2git --blobfile ../cvs2git.blob --dumpfile ../cvs2git.dump \
--username '(no author)' --fallback-encoding utf-8 ../firebird2

# Create and fill the Git repo
mkdir ../firebirdgit
cd ../firebirdgit
git init
cat ../cvs2git.{blob,dump} | git fast-import

git fast-import is that is really fast (a few minutes)
what is left to do is to export it over ssh or web

git clone --bare /tmp/firebirdgit/.git /tmp/firebird.git
and you can test it over remote
cd ~
git clone foobar@localhost:/tmp/firebird.git

qgit




the only problem left is how do i do it daily to be pushed to gitorious ?

Using #Fedora #Linux day two (Ubuntu maniac perspective)

Installing skype for 64 bits fedora is harder than on #ubuntu

sudo yum install qt-x11-4.5.3-9.fc12.i686
sudo yum install qt-4.5.3-9.fc12.i686

configure it to Not use the pulse audio

arora browser is 0.10.1 with qt 4.5.3 , it's crashing if i use gmail.com and then close the tab
known bug , that i have reported to arora (seems to be fixed in qt 4.6 and arora from ubuntu karmic)

qtcreator is called qt-creator and is at version 1.3 in fedora !

next is to find where is qmake

Screenshots in #php using #qt #python or #c++

I used the example from this article

and installed the needed libs on the server
sudo apt-get install libqt4-core libqt4-webkit python-qt4 xvfb


wget http://github.com/AdamN/python-webkit2png/raw/master/webkit2png.py


python webkit2png.py -x -o cnn.png --debug http://www.cnn.com

chmod +x webkit2png.py

from php

passthru("/home/mariuz/webkit2png.py -x -o /tmp/google.png --debug --scale 100 100 http://www.google.com")

i want to load a page with flash content , shameless plug reea.net

webkit2png.py –scale 200 200 -x -o reea.png –debug http://reea.net

but seems i have an flash error and the image is quite empty

Adobe Flash Player: gtk_clipboard_get(GDK_SELECTION_PRIMARY); failed. Trying to call gtk_init(0,0);
Xlib: extension “RANDR” missing on display “:99.0″.

also got the same error with gnash

I have investigated the c++ websnap examples from qt labs now hosted in git

http://labs.trolltech.com/blogs/2008/11/03/thumbnail-preview-of-web-page/

Another example in c++ is on this page and have made it compile on qt 4.5.3

and added

view->page()->settings()->setAttribute(QWebSettings::PluginsEnabled,true);

Using #Fedora #Linux day one (Ubuntu maniac perspective)

I liked some things on fedora 12 and i wanted to test it and and use it for a week or two (on distrowatch i saw this idea of rotating linux distributions once in a while)

I downloaded kde spin http://spins.fedoraproject.org/kde/ and installed on secondary partition the installer was a little harder to gasp than the default ubuntu one (from what i remember) Maybe the partition editor should need a little care for example fiber channel is weird to apear in the menu at advaced partitions options, I was expecting something else .

Another thing i didn't liked it is why on earth i need root user and after that i need to create my user anyway ?, Do it once and make it do sudo I was expecting to be in the sudo group and admin by default like is in ubuntu

What was nice about installer is it finished whithout to many questions and after reboot i configured the user . Maybe it should be the same for ubuntu installer : Less questions for installer and then copy the files from cd/dvd

First thing i disabled is of course selinux (security insanity should be an option and feature not enabled by default)

What was nice that disk image was transfered to the the partition so no extra package install time like in debian .
Another bonus for updates is that is using xz by default and only what is changed is updated


(primary partition is ubuntu)



First i installed adobe flashplayer 10 (64 bit version)
http://labs.adobe.com/downloads/flashplayer10_64bit.html

wget http://download.macromedia.com/pub/labs/flashplayer10/libflashplayer-10.0.32.18.linux-x86_64.so.tar.gz
tar -zxvf libflashplayer-10.0.32.18.linux-x86_64.so.tar.gz
mv libflashplayer.so /usr/lib64/mozilla/plugins/

Debugging #Firebird and #Drupal #php #pdo driver

I started by installing latest php : 5.3.1 rc3 and then with the help of ddd

I can step and put breakpoints in the driver source

cd /opt/build/php-5.3.1RC3

sudo ddd /usr/sbin/apache2





Load the drupal install and follow this guide

also I have started to use the debug_backtrace to figure the error without text that i have (empty exception text)

print_r(debug_backtrace());

#qt 4.6 beta ppa for #ubuntu #karmic , soon I will upload #arora soon

Use it at your own risk https://edge.launchpad.net/~mapopa/+archive/qt4.6

I used the qt preview tp1 and sometimes it crashed so needed the new beta ,
I  tested it on my kde desktop + I will upload arora recompiled with 4.6 version soon

The arora from karmic should work ok with 4.6 too but maybe a
recompile is needed
before you upgrade is better to save your list of pachages

dpkg --get-selections > installed-software.log

then you can reinstall qt/kde packages from console if you have problems with (revert to qt 4.5.3 if you want)
with

sudo dpkg --set-selections < installed-software.log
sudo dselect

and press I to install all the packages saved

On my sistem i had before qt tp1 packages and in deb name i had "tp1" > "beta1" if you think as a
package manager so i had to remove all qt packages and kde too and
reinstall them

sudo apt-get purge libqtcore4

Then i did the steps from above

#nginx and #wsgi on #ubuntu howto

I wanted to install mod_wsgi for nginx on ubuntu here are some basic steps for compiling it


wget http://sysoev.ru/nginx/nginx-0.7.62.tar.gz
tar -zxvf nginx-0.7.62.tar.gz
hg clone http://hg.mperillo.ath.cx/nginx/mod_wsgi/


wget http://lophus.org/~fred/mod_wsgi_patch.diff
see why you need that patch
cd mod_wsgi/
patch -p1 < ../mod_wsgi_patch.diff
cd ..


cd nginx-0.7.62/
./configure --add-module=../mod_wsgi/ --with-debug
make
sudo make install

How can i use linux low level/posix api with #qt ?

well i was searching the google about the above question and i remembered that you can use c api in c++ like any other function

you can see these posix linux threads examples that can be compiled with c++ like this $ g++ -lpthread pthread1.c


Next step was to create a simple example with qt creator 
something like get_pid.c example from advanced linux programming book 


so after an empty gui project is created do small modification like this and run it 


it should give you no errors and it should print in the console the pid 



Starting /home/mariuz/work/qtgetpid/qtgetpid/qtgetpid...
/proc/self reports process id 7977
getpid() reports process id 7977

I know that this via netbook does have issues with powermanagement and i want to digg deeper
to get some sort of power/instructions trace
so i have installed powertop


sudo apt-get install powertop
what is interesting C3 state (sleep) is buggy on this cpu (cache incoherent)
and i see that is really used , it should be disabled by bios but i know that bios is buggy too.

Powertop suggested this
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs

so i have added it in /etc/rc.local
before the exit 0

Building #Firebird 2.5.x extension for #Php 5.x.x on #Windows

Follow the advice on howto compile php on windows with visual studio express (yucks)
http://wiki.php.net/internals/windows/stepbystepbuild
I  will not copy paste all  the steps here , a short document makes them easy to follow


1.Install visual Studio Express C++ 20xx
http://www.microsoft.com/express/Downloads/#2008-Visual-CPP
2. get and install windows sdk 6.1
3. get a php 5.3 snapshot or any stable version 5.x (do not extract yet!)


Next is is to download a zip file with firebird 2.5.x final from sourceforge 


in my case http://sourceforge.net/projects/firebird/files/firebird-win32/2.5.2-Release/Firebird-2.5.2.26540-0_Win32_pdb.zip/download


Next is to unzip the files from bin,include,lib
into C:\php-sdk\php53dev\vc9\x86\deps


enable firebird extension from the build console (By default thread safe version is build )


configure --disable-all --enable-cli --with-interbase 
nmake 
cd Release_TS
php -m 


should show you that interbase/firebird extension is there 








If you want to create the shared dll for the firebird extension you need to provide 
--with-interbase=shared to the configure script
otherwise it will be included in the big php executable 
Another note is if you do use IIS with fastcgi then you must disable threading support (Non Thread Safe ) in the configure part you must add --disable-zts



Update:
The work to compile full firebird 2.5.x server with visual c++ 20xx and $sudo make the php core developers happy is DONE (the firebird extension it will be included by default in official php 5.3.4 zip file for windows)

You don't need #OpenDNS , you have your own dns server on #Ubuntu !ubuntu

Install isc bind server

sudo apt-get install bind9

test if the dns query works

$ dig reea.net @127.0.0.1

make it default resolver for your system

sudo pico /etc/resolv.conf

or open it with any editor

sudo kate /etc/resolv.conf
add this entry
nameserver 127.0.0.1

delete all other nameservers or comment them if you want

and that is all (tested on ubuntu karmic and intrepid)

debtree-next - better #Firebird package dependecies graphs in #debian #ubuntu

Inspired by the new dbtree from git now you can do a clean graph for the packages in debian and ubuntu

$ git clone git://git.debian.org/~fjp/debtree.git
Here is the graph for installed files for firebird2.1-classic

$ ./debtree --no-recommends --no-conflicts -I -S firebird2.1-classic >out.dot
$ dot -T png -o out.png out.dot



Here is the graph for installed files for firebird2.1-supper
$ ./debtree --no-recommends --no-conflicts -I -S firebird2.1-super >super_out.dot
$ dot -T png -o super_out.png super_out.dot



Now you can do reverese dependency graph , here is the example for libselinux1 if you dare to remove it

$ ./debtree -I -R --no-recommends --no-conflicts libselinux1 > libselinux.out
$ dot -T png -o libselinux.png libselinux.out
$ gwenview .

Howto change #Firebird password in #Ubuntu , #Debian ,#Linux

On Ubuntu with firebird 2.1 you can change password if you forgot it this way
1.First method
$sudo gsec -modify sysdba -pw 123456 (we trust root user muhahaha)

2.Second method
$sudo su
cd /var/lib/firebird/2.1/system
cp default-security2.fdb security.fdb
$ /etc/init.d/firebird2.1-classic restart

3.Third method
$ sudo dpkg-reconfigure firebird2.1-classic

On windows if you are in the Administrator group i guess you can change it with gsec from command line
C:\Program Files\Firebird\Firebird_2_1\bin> gsec -modify sysdba -pw 123456

#Firebird , #Mysql and Not NULLs + Stored Procedures

Last night/morning i have read again some rants against the NULLs in one of the CJ Date book SQL and the Relational theory and in practice it's is true that I found one table with something like 20% of it filled with nulls (not normalized) and let's say that count(*) is in the range of millions , Now you have a lot of scans for data that is not there So is better to split that table and normalize it also the columns should be NOT NULL by default for example EMPLOYEE_ID

Now comes the good part you don't need to pollute the queries with NOT NULLS anymore and you get more speed , it depends how many nulls you had before (of course there are opimizer tricks to do some shortcuts)
and save the plannet for overheating

On mysql i eliminated not null check from one query it didn't improved too much the speed (~0.2s ) but at least it's easier to read
on firebird side it improved performance but again not so much (~0.2 s)

I started to create a selectable stored procedure and at least in firebird part it was faster 0.2s vs the query without selectable sp

In the end i got 0.4 seconds only by eliminating NULL from the query and creating a selectable procedure

wicd vs network manager on karmik

I have installed wicd by a simple 
$ sudo apt-get install wicd 

it removed network-manager and network-manager-gnome 

what do you get ? a better wireless manager , seems that it connects to the network before the gui 
gets started so from the console i can upgrade or dist-upgrade 
and it works from any DE: gnome/lxde/kde ... 

For the moment i will stick to it 


Caking for FUN+Profit

Here is my  presentation prepared for php meetup in boston but also was showed at
geekmeet #2 from Targu Mures

Firebird, mysql and CXXFLAGS

I have tried to optimize the speed for mysql and Firebird but for the moment
it seems for that particular query there is no difference (io starved) , maybe i need some queries with math calculations to see the benefit for thouse flags

On the firebird side seems that CXX flags are not considered at all and i will inspect why 

Here are my flags anyway

http://paste.ubuntu.com/266785/

The good news is that at least make -j2 should work for firebird HEAD
Update: seems that it works if I export only the CXXFLAGS

export CXXFLAGS="-O3 -march=core2 -mtune=core2 -mfpmath=sse"

Firebird 2.1 dependency graph in ubuntu

I was reading about debian and ubuntu bloat growing , more useless packages are installed by default
Read the full article here

"For comparison, the size of a default Gnome desktop install for Etch was 1360MB; for Lenny it is 1830MB; for Squeeze it looks like it will be well over 3000MB! Remember that for Sarge we installed both Gnome and KDE from CD1 with both together taking 1390MB?"

So i wanted to create a dependecy graph for firebird using Debtree
http://alioth.debian.org/~fjp/debtree/

All you need is to install the debtree package , seems that is not included by default in ubuntu So click here
http://alioth.debian.org/~fjp/debtree/debtree_0.7.3_all.deb

$ debtree firebird2.1-super >out.dot
$ dot -T png -o out.png out.dot

#Mysql 5.4.x from source on #Ubuntu #Karmic #Server #x64

I needed to run mysql5.4.x compiled from source , the version from ubuntu is old 5.1.x
and for this i had to do following steps
Follow the download link for mysql

http://dev.mysql.com/downloads/mysql/5.1.html#source

$ sudo apt-get build-dep mysql-server

Download the last source code archives for the mysql :

Tell me that centos doesn't suck on desktop

do you want gnome > 2.22 as required by some software please be prepared to compile gnome with garnome
And i'm not the only one that knows that sucks on the desktop side
Here is what Caitlyn Martin has to say
"Look, stop trying to convince me. I've removed CentOS from my netbook and I'm about to explain why. As far as I am concerned it's good riddance to bad rubbish. CentOS is a wonderful server OS clone. On the desktop I have no use for it."



18 Years ago Linus started the Revolution

Do you Remember 18 years ago when Linux was conceived? , and look now the biggest threat to Microsoft. Finally it has grown up! http://www.wired.com/thisdayintech/2009/08/0825-torvalds-starts-linux I just can wisper some words to them : Ubuntu , Android , Netbooks (yah they defeated us on that one) , Nokia Maemo , PalmOS ... Ohh and i forgot Google . I still can read and run the assemmbler/C code from linux 0.0.1 and the starting point code was good in the sense that it worked and it was inspired by good concepts from Unix , Of course linux is not unix is something else alive and with good future.It's funny to read the comments about the portability and that it works only on his 386/harddrive , Look now i have an Android phone with Linux on and i'm free to modify it and do whatever is in my mind no one stops, try that with Iphone or windows CE devies . It's all about the freedom to hack (in good sense) and give back

sorting directories by disk usage

I needed to sort directories by disk usage using du and sort , but there was a problem with dirs that start with "-"

$du -s *

gives this error "du: invalid option --"

So i had to put the directory list result in a file:

$ find . -maxdepth 1 -type d -name '*' -print0 >file_list.lst

then i used the --files0-from

$ du -sm --files0-from file_list.lst | sort -n

seems that i needed to show the timestamp --time and maybe to exclude the "thumbs.db" from the report --exclude="thumbs.db"

$ du -sm --exclude="thumbs.db" --time --files0-from file_list.lst | sort -n

SQL compliant ROWS syntax obviates the need for FIRST and SKIP in Firebird

Today i found rows new syntax for first/skip that is more standard compliant

SELECT *
FROM POSTS a rows 4 to 6
nice that it works with update/delete too

extracting date from an timestamp value in firebird

you can use the cast to extract the date from timestamp

SELECT cast('now' as date)
FROM rdb$database

in my case the result is

28.07.2009

someone asked on webhostingtalk how to do it

also you can extract only the year or month using the extract function

No wonder flash streaming is everywhere at least it works , crappy but it does work
And ogv is way better for streaming than flash / silvernight

[UPDATE:seems that stream is not allowed in Romania so kudos to mono team
Also i have tested the stream from vlc seems that akmai doesn't allow the stream to Romania

Recovering ubuntu karmic with an intrepid cd

i did an sudo apt-get dist-upgrade in karmic
and it removed upstart upstart-compat-sysv upstart-logd

I have to force from live cd to mount the partition as "-t ex4dev"

#mkfs.ext3 -E test_fs /dev/
$sudo mount /dev/sda1 -t ext4dev /mnt

$sudo chroot /mnt
seems that i need to downgrade upstart
install
system-services, and reinstall startup-tasks

I got the kdm prompt, had some weird errors with /dev/null when i logged in from the console (Alt F1)
so i upgraded to upstart 0.6 and again the system doesn't do the init or runs the scripts
maybe i need to put it in DEBUG mode
Now i'm studying the upstart main.c code and I wish it was written in python or any scripting language

Quote of the day is about Chrome and features

Per-process execution is a feature in Chromium (Google Chrome), not V8. And it is really needed anyway if one is using V8, because V8 is not thread safe.

So that is why you have one process for Tab in chrome (it's a bug called feature in V8)

git cvs-import gotchas on ubuntu and using firebird repo

I started to import the firebird cvs repository into my local git mirror.Why ?
Maybe because the bzr import failed after >30 hours ! also seems that fisheye is dead no changes to changelog there.
So my plan is to import the firebird cvs using git cvs-import and then push it to gitorious or bzr launchpad later (request a new git to bzr import)

First you need to install git-core and git-cvs
$ sudo apt-get install git-core git-cvs

you need to create the firebird2 dir with
$ mkdir firebird2
and specify it when you do the import with "-C firebird"
then you need to add the repository path from sf.net
"-d:pserver:anonymous@firebird.cvs.sourceforge.net:/cvsroot/firebird"

First you need to do cvs login
$ cvs -d:pserver:anonymous@firebird.cvs.sourceforge.net:/cvsroot/firebird login

Here is the complete command line for importing firebird in local git repository

Arora is default full featured browser in Kubuntu

Arora is a simple cross platform web browser whose feature list includes things like "History" and "Bookmarks". It has a small code base and loads of fun to hack on. Benjamin Meyer originally created as a demo for Qt to help test the QtWebKit component and find API issues and bugs before the release Arora works with almost all websites and offers nice features like HTML 5, but needs some more features to give it the same parity as existing browsers. Arora should work with Web 2.0 websites we consider to be critical to our users. These include Slashdot, GMail, Google Calendar, Facebook, Flickr, Youtube, Yahoo and of course kubuntu.org.
[ED: tested the Slashdot , reddit , gmail , facebook , youtube, flickr and yahoo and all work OK , also wordpress.com and firebirdnews.org admin area
Arora passes 99/100 tests from acid3 tests also gets good scores on browser benchmarks http://service.futuremark.com/peacekeeper/results.action?key=1Ei0

sudo apt-get install dosbox
mkdir ~/dosbox/c
copy the volfied files from the zip in
~/dosbox/c/volfied
dosbox
mount c /home/mariuz/dosbox/c

cd volfied

Here is how i installed the tor network privacy proxy

sudo pico /etc/apt/sources.list.d/tor.list

deb http://mirror.noreply.org/pub/tor jaunty main
deb-src http://mirror.noreply.org/pub/tor jaunty main

sudo apt-get update
sudo apt-get install tor

sudo pico /etc/privoxy/config

add this line at the end of file

forward-socks4a / localhost:9050 .

sudo /etc/init.d/privoxy restart

add http proxy in System -> Preferences -> Network Proxy
Http proxy: 127.0.0.1
Port:8118
and
Secure Http proxy: 127.0.0.1
Port:8118
