Virtuemart filter by availability in stock

If you want to sort items by "in stock" then i have hack for you :)

Firstly edit file: /administrator/components/com_virtuemart/html/shop_browse_queries.php
After lines:

$featured = vmGet($_REQUEST, 'featured', 'N' );
$discounted = vmGet($_REQUEST, 'discounted', 'N' );

Add this line:
$in_stock = vmGet($_REQUEST,'in_stock','N');

Also in that file after these lines:
if( strtoupper($featured) == 'Y' ) {
    // Filter all except Featured Products (="on special")
    $where_clause[] = '`#__{vm}_product`.`product_special`=\'Y\'';
}
if( strtoupper($discounted) == 'Y' ) {
    // Filter all except Discounted Products
    $where_clause[] = '`#__{vm}_product`.`product_discount_id` > 0';
}

Add this:
if( strtoupper($in_stock) == 'Y' ) {
    // Sort in stock
    $where_clause[] = '`#__{vm}_product`.`product_in_stock` > 0';
}



Now edit file components/com_virtuemart/themes/<your theme>/templates/browse/includes/browse_orderbyfields.tpl.php

And in the end add:

<select class="inputbox" name="in_stock" onchange="order.submit()">
<option value="N" >All</option>
<option value="Y" <?php if (isset($_REQUEST['in_stock']) && $_REQUEST['in_stock']=='Y') echo "selected"; ?>>In stock</option>
</select>

Now you can filter products by availability in stock :)
Check in virtuemart control panel if you checked ordering by fields ;)

Cant flash STM32VLDISCOVERY with st-link utility or other.

If you can't flash your stm32vldiscovery try to disable any virtual disk like daemon tools.
It works for me.

Warzone 2100 automatic music.wpl file refresher

In Linux, all you need is to place your ogg files in .warzone2100/music
and execute script.

Firstly create in that directory file - refresh.py
Code:


#!/usr/bin/python
import os


f=open("music.wpl","w")


dirList=os.listdir(".")
for fname in dirList:
    if fname.find(".ogg")>-1:
        print "Writing ",fname
f.write(fname)
f.write("\n")


f.close()


then make it executable.
Place your ogg's and run this script

How to simply use arduino as usb-uart ?

Its very simple.

Conect RESET pin with GND, so you will turn off your Atmega.

Now the Rx and Tx pins are free to use.DONE! :D

But if you want RS-232 then you will need MAX232 chip or similar.

How to program AT89S51 from Arduino

Its simple,because at89s51(you can program also other atmel chips,if you will change some code) uses serial programming interface (ISP).
In arduino we must only use SPI library.You can watch it in sketch.

Arduino sketch: ARDISP

Also i made Small console java program,that use virtual com(change to your COM port in Netbeans) for programming .hex (you can create your own program),just watch at89s51 datasheet for serial programming codes.Run in console(in dist directory) with: java -jar ArdIsp.jar COM2 main.hex (if doesnt work,maybe place win32com.dll in windows dir)
Java program

Please add your comments!

Bash for in one line

[~/src] for f in *; do echo $f; done
bin
lib
src

I hope you got it.

for (something) in (some array); do (do something); done

About Linux Mint

Linux mint is mine favourite linux distribution.
It is based on ubuntu,so it has a lot of packets and good mirrors.
But also it has good artwork and easy to use interface.
