SPECIAL NOTES:

- For Cable, Converter and Energy modules, every time brand, model, property etc. data are
added/edited/deleted, a backup version of the database is stored in the relevant module's
data folder, e.g. ./LibreEngineering/data/cable/cable.sqlite~. To go back to the previous
version of the database, simply delete the existing data base file (e.g. cable.sqlite) and
remove the '~' symbol from the back-up file name.
- It seems there is no SVG support in PortablePython-2.7.3+'s version of Qt.


PREREQUISITES:

I NEED ENGINEERS AND PROGRAMMERS HELP

I would like to add many more engineering calculations, e.g. orifice plate, PSV, control
valve etc. but I am not a process engineer, so making the research and applying correct
formulas is a very time consuming process. I will greatly appreciate anyone's help who
has a process engineering background. Please provide the sizing calculation formulas
so that I can write the calculation module. Any results verification help will be greatly
appreciated.

As I am not a programmer, the code may not be perfect. But I will also greatly appreciate
any help with programming, e.g. making the code better, fixing bugs, adding features.


SPECIAL THANKS TO DEVELOPERS AND SUPPORTERS:

- Yuri Bongiorno for support with Codec
- WinFF for Ffmpeg presets
- OpenClipart for artwork
- Python, Qt, PyQt, PyEnchant, LibreOffice, SQLAlchemy, SQLite
- Joakim Low from PythonWare for PortablePython Windows Registry script
- sqlitefktg4sa for SQLite Foreign Key Trigger Generator for SQLAlchemy




Changelog:

- NEW Pipe sizing calculator
- NEW Compressor sizing calculator
- various bug fixes and improvements

Теоретически да, но практически к сожалению в ближайшем будущем нет, т.к. на перевод уходит огромное количество времени, которого у меня просто нет. Буду только рад если кто-нибудь поможет с переводом.

К сожалению, я то же сейчас занят, однако буду иметь в виду. И кстати, базы данных, те которые sqlite, не подключаются у меня почему то. Файл выбираю, но ничего не происходит, то есть соответствующий модуль не работает.

Я попытался установить всё с нуля и (после того как нашёл идиотскую ошибку) всё работает. Проверил и в Windows и в Linux. У тебя что стоит? Если Windows, то самый легкий способ установить SQLAlchemy:

1. Download setuptools from http://pypi.python.org/pypi/setuptools#downloads
2. Install setuptools
3. Open command prompt and execute this:
C:\<PATH_TO_PYTHON>\Scripts\easy_install.exe SQLAlchemy

А если Linux, то SQLAlchemy должен быт частью дистрибутива. (см. http://docs.sqlalchemy.org/en/latest/intro.html#installation)

Если интересен вывод в консоль, то напиши мыло в личку, скину. Сюда вываливать нет смысла, как мне кажется.

 I made a blunder

 
 by linuxoidoz on: Mar 15 2012
 
Score 50%

It turned out my experimental player which I've only started but which relies on VLC prevents the whole package from starting if VLC Player is not installed (I have it installed so it never was a problem until I tried to make a full Python-PyQt-SQLAlchemy install in VirtualBox).

So, if you don't want to download LibreEngineering again, just open 'formwidget.py' in LibreEngineering folder and comment out this line:

#from applications.player.mainwindow import Player

Hi, I'm no programmer at all, but I'm an Engineer and have some ideas and could help :)
But for starts, how about set a PPA or something to be able to install your promising program?

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
