Poor man's wget for Windows

Windows not only is an awfully stinking mastodon, but it even lacks the most basic tools commonly available on Linux, such as telnet and wget.

I have found a bare bones wget implementation for Java and duly simplified (I love to strip away all useless exception handling)

import java.io.InputStream;
import java.io.DataInputStream;
import java.io.BufferedInputStream;
import java.net.*;

public class JGet {
    public static void main(String[] args) throws Exception {
        if ((args.length != 1)) {
           System.err.println("\nUsage: java JGet [urlToGet]");
           System.exit(1);
        }
        String url = args[0];
        URL u;
        InputStream is = null;
        DataInputStream dis;
        String s;
        try {
           u = new URL(url);
           is = u.openStream();
           dis = new DataInputStream(new BufferedInputStream(is));
           while ((s = dis.readLine()) != null) {
               System.out.println(s);
           }
        } finally {
           is.close();
        }
    }
}

windows remote desktop: The Local Security Authority cannot be contacted

Trying to connect to a Windows 7 Desktop, using "windows remote desktop", get this very explanatory message "The Local Security Authority cannot be contacted".

After wasting one hour to find an appropriate monitor to connect to the box, I discovered that simply the password expired.

Just one extra (of the already billions) reason to hate Microsoft.

Getting rid of Windows line feeds

This script to find infected files:

#!/bin/sh

PATH_TO_SCAN=$1

if [ "${PATH_TO_SCAN}" == "" ]; then
    PATH_TO_SCAN="."
fi

FILELIST=$(find "${PATH_TO_SCAN}" |egrep '\.(java|xml|js|groovy|sql|csv|txt|py)$')

IFS_BCK=$IFS
IFS="
"

for FILEPATH in ${FILELIST}; do
    cat -v "${FILEPATH}" | grep -I -q '\^M'
    if [ $? -eq 0 ]; then echo $FILEPATH; fi
done
IFS=$IFS_BCK

In Eclipse: Windows Preferences, then search "encoding" and set "line terminator" to Unix and Encoding to UTF-8

To convert infected files, in Eclipse do "File/Convert line terminator to..."

Otherwise, in Notepad++ use "edit /EOL conversion"

VirtualBox: Running a 64 bit host RHEL OS on a 32 bit Windows machine

My VBOX is a

facter | more

architecture => x86_64
hardwareisa => x86_64
hardwaremodel => x86_64
kernelrelease => 2.6.32-279.el6.x86_64
kernelversion => 2.6.32

processor0 => Intel(R) Core(TM) i5-3437U CPU @ 1.90GHz

so it clearly expects a 64 bit OS and 64 bit Processor.

My CPU is clearly up to the task, but the host OS is clearly not (Windows 7 32 bit)

Contrary to popular belief, it can be made to work, as long as you are allowed to enable VT-D hardware virtualization in your BIOS (most likely you will have to provide a password).

This is documented here http://www.virtualbox.org/manual/ch03.html and here http://www.virtualbox.org/manual/ch10.html#hwvirt.

I have managed to make it work on my laptop, but it has crashed several times with a BLUE SCREEN OF DEATH. This seems to happen whenever I hibernate my computer while the Vistual Machine is up and running.

Once more I really regret having to use a Windows guest OS to work...
