TCP Client

Connect to any host on any TCP port, send data, and read the remote reply. Remembers what the last host/port you used was.
Enter the host name or IP address, and the port. Click connect. When you connect, the Send button will turn green. Type some text into the top left box, for example, "GET /page.htm HTTP/1.0 \n\n" (where \n represents a carriage return). Do not forget new lines at the end of your request when speaking to an HTTP server! When the server replies its text is displayed in the large box.

WAN IP

Open this program and give it a moment to connect to my server. It will display your internet address. Remember your WAN IP address will be different from your LAN address (unless you are the gateway machine). For example, my machine has internal address 192.168.0.1 but when I surf the web servers see my WAN address as 217.1.2.3. The gateway machine has two addresses, one in the 192.168.0.0 range and one in the 217.1.2.0 range. This way my network uses only one ICANN IP address (217.1.2.3) even though there are many machines connected (indirectly) to the public network. If only MIT was as conscientious as the rest of us!

Template (edit this with your address and this Birthday's news, save as thanks.dot):

Program (insert friend's name etc):

Port Scanner

Enter the first three bytes and the trailing dot of an IP address (e.g. "127.0.0."). Click go and a file containing all the open ports will be given. Running this on my machine gives the following:
Starting 15/Mar/2003 17:40:53
127.0.0.1 80
127.0.0.1 135
showing the only open ports are 80 and 135.
The data is saved in a file "127.0.0.1.txt".
When all 65535 ports on this address have been scanned, the next address (127.0.0.2) will be scanned.
When all 256 addresses in this range have been scanned (i.e. after 127.0.0.255 has been scanned) the program stops.
Must not be used maliciously. Intended as network administrator's security analysis tool. Daniel Clarke waives all responsibility.

Limitations: scans ports consecutively so takes bloody ages. But it's not bad for about 20 lines and 20 minutes (VB) !

N^th Root Calculator

z = x^1/y
example: 3 = 27^1/3
Enter the values for x and y and click Go. You will be given the value for z.

Remember that
x^1/y = e^(1/y)ln(x)
which is really easy to code and for a computer to calculate.

Remember also that to add, computers do not add directly but use logs of products: z=x+y :
e^z = e^x+y = e^xe^y
so
z = ln(e^xe^y) (no addition needed!)

GUID

Generate a unique ID number.

Microsoft allegedly guarantee that the number made will be unique no matter how many machine generate one.

Use the straight 32-byte hex string like CE01D8DE88BB475F81002DFB12E0D0AC or the registry-adapted string {CE01D8DE-88BB-475F-8100-2DFB12E0D0AC} which allows you to easily create unique class IDs.
As sold elsewhere for $10 - free here!

Guitar Tuner

Play reference tones to tune your guitar to.
Allows you to load different tuning configurations so that you can quickly tune in another style. For example, to play Led Zeppelin's Kashmir you need to retune most of the strings.
There is also the option to use "Metal" tuning - lowering the pitch of each note by one semitone - so that you can accurately tune to play along with Guns N Roses and other bands that use this method.
No other guitar tuner allows the pitch of the notes to be changed!

 
Notice the alternartive set of notes in the "Kashmir" tuning on the right. Download

Free Space Monitor

Monitors free disk space and send you a warning email.
Have you ever found that things were running slowly and then seen that one of your drives was nearly full? I have!

FSM discreetly monitors the free disk space on any given drive (local or mapped). Sends you an email when the space on a drive falls below a given threshold (different threshold for each drive).
Runs invisibly at startup.
NB. For IE6 users, if you have the "Warn me when other applications try to send email as me" option ticked in Outlook Express, Windows will ask you to confirm each email sent. This is for security. To remove it: Outlook Express > Tool > Options > Security > Untick "Warn me when other applications try to send email as me"
