Sad Review of Solar Winds IP Address Tracker Tools

I was hoping to find a good, simple, tool for tracking IP address assignments. My first choice was Excel, but I thought someone must have an easy to use program for this common task. After a quick Internet search I found, Solar Winds www.solarwinds.com

I installed the Solar Winds Free IP Tracker using their installer “SolarWinds-IPAT-FreeTool-v4.3.exe” but was never able to run the program. It seems to install. I definitely see a lot of background processes running for it. I just can’t get the program to launch without an error.

I contacted Solar Winds to report the problem but it has been over a week and still no response. I am sad to say all of this and must recommend that you Do Not Use Solar Winds products.

Using LUA in a C++, Visual Studio 2013, Qt, or any C/C++ application

Start Super-Quick-Start Guide:

  1. Download and extract the LUA source.  Click here
  2. Add all of the .c files in the “src” directory to your project except for lua.c and luac.c (these are the interpreter and compiler that are not needed for this example and, depending on your use, are not needed at all)
  3. Add the path to the LUA headers to your project include paths. For example:
    “lua-5.3.1/src”
  4. Assuming you are using C++, add this line to the top of your source to include the headers needed in a C++ friendly way:
    #include “lua.hpp”
  5. That is it!  You are all set and ready to use LUA in your program.
  6. OK, here is an example to get you started!
const char* luaScript = "\
addCount=0\n\
\n\
function addTwoNumbers(x,y)\n\
  addCount = addCount + 1\n\
  return (x+y)\n\
end\n\
\n";
int luaScriptLength = strlen(luaScript);
int addCount;
int addResult;

// create lua and load the script data
lua_State *L = 0;
L = luaL_newstate();
luaL_loadbuffer(L, luaScript, luaScriptLength, "luaScript");
lua_pcall(L, 0, 0, 0);

// get value of addCount global variable
// stack addCount
lua_getglobal(L, "addCount");
// value of top stack item (in this case addCount)
addCount = lua_tointeger(L, -1);
// addCount should be 0
// unstack var1
lua_pop(L, 1);

// add two numbers
// stack addTwoNumbers
lua_getglobal(L, "addTwoNumbers");
// stack value 5
lua_pushinteger(L, 5);
// stack value 10
lua_pushinteger(L, 10);
// call 2 stacked args, 1 stacked function, and expect 1 stack result
lua_pcall(L, 2, 1, 0);
// value of top stack item (in this case the addTwoNumbers result)
addResult = lua_tointeger(L, -1);
// addResult should be 15
// unstack result
lua_pop(L, 1);

// get value of addCount global variable
// stack addCount
lua_getglobal(L, "addCount");
// value of top stack item (in this case addCount)
addCount = lua_tointeger(L, -1);
// addCount should be 1
// unstack addCount
lua_pop(L, 1);

lua_close(L);

RED – change quoted strings

Your Regular Expression of the Day (RED) is how to change a quoted string in C/C++.  This is a bit complex, but hopefully it will be a good starting point.  It will allow some start characters to be captured, followed by the quoted string, and finally some end characters.  The captured data can then be used with whatever additional data you want to insert.

RED: ([,\( ])\”(.*)\”([,\) ;])

In VS2013, the Replace with string would be: $1_T(“$2”)$3

Enjoy!

TI CC3200 LaunchPad Gotcha

Important things to note about the CC3200:

1.  You can get the launch pad from Digikey for about $30

2.  If you follow the Getting Started Guide, make sure you also try the following when the Code Composer connection fails:

A.  press the reset button on the board before debugging

B.  Do Not open your serial port terminal application until after the debug session has started (or it won’t start at all)

3.  Code Composer is pretty low-level and may ultimately be unnecessary.  You may get faster results using Energia

FreeNAS Using External USB Hard drive formatted FAT32

Here is how to use an external hard drive on FreeNAS as a plain FAT32 drive.

1. create your partitions and format the drive

Show paritions:
gpart show da0

Delete existing partitions:
gpart delete -i 1 da0
gpart destroy da0

Create new partitions and format:
gpart create -s gpt da0 (create the span for the whole disk)
gpart add -t mbr da0 (create the slice (partition))
newfs_msdos -F32 /dev/da0p1 (format it as FAT32)

Mount the partition to an existing directory <mount point>.  For example: /mnt/usbhd:
mount -t msdosfs -o large /dev/da0p1 /mnt/usbhd

2. When you are done, just unmount the drive using:
umount <mount point>

That’s it!  Now you can stop searching through all of the Internet to find the answer 🙂

Z-Wave Project – Day 1

I installed two Linear WD500Z-1 Wall Mounted Dimmers this morning.  You need a lot of space because of the extra wires and wire nuts involved.  You also have to remove the tabs that would overlap in the 2 gang box.  These tabs are apparently heat-sinks, so that reduces the max watts supported from 500W down to 400W.  Still, I got them to fit and they work perfectly.

Now I want to control them remotely, which is why I bought them in the first place.  I am using a hand-held controller, the Intermatic HA07.  It was easy to setup the controller, but the trick was getting the Linear dimmers to be included into the network.   To make the Linear WD500Z-1 dimmer listen to the remote, first Delete the dimmer from the network by pressing delete on your controller and tapping up on the dimmer twice.  Tapping up twice is the most important step that was not obvious from the Linear documentation.  Next to include the dimmer in the network, press Include on the controller and tap the dimmer up twice.

Next I need to assign channels, lighting levels, and program the timer.  Should be easy 🙂

 

PS4 cannot play 3D movies (No Wait, Now it CAN!)

Update!  It would seem as of firmware v1.75 the PS4 can play 3d movies.  I have yet to have time to try it, so hopefully it works and is amazing!

I needed a blu-ray disc player for my PT-AE8000U projector.  I was using a PS3 that I had moved from downstairs and thought that I would buy the new Playstation 4 for the theater room.  News Flash. As of System Software Update 1.62 the PS4 is still unable to play 3D blu-ray.  That is correct, the old PS3 can but the new PS4 cannot.  Who would have guessed?

While I am at it, I must say I am disappointed with the movie playback of the PS4.  The controller L2 and R2 buttons are so easily pressed by accident that I dare not touch the controller while watching a movie.  It is also annoying that a notification pops up over the movie when the controller automatically disconnects (no this particular notification cannot be disabled).  When you want to reconnect the controller to pause the movie, it takes out the entire screen to make you select the user for the controller.

Don’t buy a PS4 to watch blu-rays, not right now.  As of March 19 2014 the XBox One doesn’t play 3D blu-ray either.

I recommend a PS3 🙂

 

Strange Internet

Facebook is using this very strange character to tell me they are going to update.  Why the character?  Why tell me they are going to update without me having a choice to stop them?  Strange Internet.
