This is not the future I signed up for.
The future was riding on light, dancing until the sun came up, smartdrugs,
technology and progress. We plugged our brains into a collective network and
became one with everything. Going to work meant walking from the bedroom to the
desk. Friends were never more than a button press away. Bandwidth was cheap and
plentiful. Road warriors carried silicon and wore leather. They were dangerous
enough to be useful, and smart enough to be trusted. We had clients, not
employers. We made contracts and resolved our own conflicts. Politics took a
back seat to technology when we spoke. Deadlines were something to be smashed.
We were in constant competition with ourselves to make ourselves better. We
worked as hard as we played, and our results proved this. Our friends never went
hungry or dry. We celebrated ourselves and coming into our own. We saw the
future with possibility not with fear. We invested in our future - the future as
we saw it: knowledge, hard work that pays off, hard play that makes it all
worthwhile. A life, not an existence. Now we face the world as you have made it.
A place where it is illegal to dance. Where we choose between eating and paying
rent. Where our work lines your pockets while we live in fear that a job well
done today means unemployment tomorrow. Our future has not died. It lies dormant
inside of us, fueling our hope and passion. A day will come when it will awaken,
and we will be all this, and more.

Spoofing Charge Number
greyarea@phreaksandgeeks.com
Ok this is something that has been very controversial to most people in the
scene these days, well at least the people who understand the whole concept of
Calling Party Number (CPN) and Automatic Number Identification (ANI). If you
don't know the difference between the two by now I can give an example and the
definitions of both to clear it up for you.
(Example given below)
1. Peter calls my phone and I have it forwarded to Doug. Since Peter is the
Calling Party Number (CPN) that will generate the CallerID to Doug and Peters
number will show up on Doug's CallerID display. However I am the Charge Number
(CN) behind Peter's Calling Party Number (CPN) because I connected the call to
doug.
2. Peter calls my phone and I have it forwarded to NPA-555-1212. Even though
he's the Calling Party Number, directory assistance will see my number because
I'm the Charge Number (CN). I originated the call to directory assistance and
they will bill me. Both calls Peter's ANI aka CN stopped at me and I became
the ANI for both calls but Peter remained the Calling Party Number. Got it..?
If not here are the definitions.
Sited: FEDERAL COMMUNICATIONS COMMISSION
47 CFR Part 64
[CC Docket No. 91-281, FCC 95-187]
(a) ANI. The term "ANI" (automatic number identification) refers
to the delivery of the calling party's billing number by a local
exchange carrier to any interconnecting carrier for billing or routing
purposes, and to the subsequent delivery of such number to end users.
(b) Calling party number. The term Calling Party Number refers to
the subscriber line number or the directory number contained in the
calling party number parameter of the call set-up message associated
with an interstate call on a Signaling System 7 network.
(c) Charge number. The term "charge number" refers to the
delivery of the calling party's billing number in a Signaling System 7
environment by a local exchange carrier to any interconnecting carrier
for billing or routing purposes, and to the subsequent delivery of such
number to end users.
Ok now that you have that down, lets move on to the fearness... All this time
everyone and their mom has thought that ANI was CPN and now you know it is not
the same thing. When spoofing Charge Number (CN) there are a couple of things
to keep in mind first.
1. You will need to know what "real" long distance provider is originating your
calls.
2. You will need to know what provider is handing the calls off to the
terminating number.
3. You will need to be able to set your Calling Party Number to your liking.
4. You will need to know if your VoIP provider is passing an ANI FAIL behind
your set Calling Party Number.
5. You will need a friend that can supply teh kind herbals to understand what
is happening.
A big handful of VoIP Providers will let you choose your CPN (which you know
generates your CallerID). That's not the ANI though because the call didn't
originate from the number you chose. Some VoIP providers will set a 10 digit
non-billable number as your ANI so you can't charge someone else's phone with it
and some of them will just simply pass an ANI Fail behind your CPN. An ANI fail
is just a 3 digit area code that represents where the number delivery
information was lost from the Originating Station ID.
There are a couple of methods when changing your Charge Number (CN) and I'll
get into the conditions now. The first method is the "Crossing platforms"
method. This is when you have an ANI Fail behind your set Calling Party Number
(CPN) and call a number that is on a different platform, for example terminating
to a number provided by Qwest and originating your call from at&t's network.
Since your call didn't start on the Qwest network their systems will receive
your Calling Party Number as the Charge Number because they received no Charge
Number (CN).
Another method that is needed to change the Charge Number on the same network
that your call originated from is called "Matching NPA's." NPA is the same thing
as an area code. So when your VoIP provider is passing that ANI Fail you will
need to find out what the NPA is and match it. Even though this method is good
for changing the Charge Number on the same platform or network it is limited to
the area code that is being passed as the ANI Fail. Getting around this and
being able to change the NPA its passing as a fail on the same network, if it
happens to be on at&t's network you can simply dial 1-800-callatt or
1-800-operator passing a ANI Fail behind your set Calling Party Number and tell
the operator the number you're calling from because they didn't get a Charge
Number, only a Calling Party Number (CPN) and they ask for it. And say "fjear
special needs operator privileges please dial 8xx-xxx-xxxx" and when they place
that call it will pass your Calling Party Number they received as the Charge
Number and that will give you the ability to choose whatever NPA you want on the
network you originated the call on.
A good tool to have is some ANAC's. Heres the definition for what a ANAC is:
Sited: google.com
An Automatic Number Announcement Circuit (ANAC) is a special telephone number
that is meant to be used by phone company technicians, phone phreaks and other
telecommunications technicians to determine the phone number of a particular
line.
One thing to keep in mind is that when calling a real ANAC it is important to
call the one that is on the same platform that your calls are being handed off
by. Otherwise you won't get the real Charge Number you will get the Calling
Party Number. So at&t to at&t, Verizown to Verizown, Qwest to Qwest and Sprint
to Sprint. Remember that when testing. I would drop some but you know what would
happen to them, sorry...
By default on a regular call this is the call flow I currently believe takes
place:
ANI generates the Charge Number, (Charge Number is what leaves the network
acting as the ANI)
Charge Number generates the Calling Party Number
Calling Party Number generates the CallerID.
This wasn't intended to be put out there for people to start charging other
peoples line either or blaming people for malicious calls. That's just plain
stupid and gives you bad karma. It was put out to show how it works and the
great vulnerability going beyond just spoofing CallerID and to help identify it
so that if somebody gets blamed for bogus traffic their lawyers have a way to
prove it didn't take place. Phreaking isn't about getting free phone calls or
any of that other shit. It's finding out how something works and recreating it
yourself or making it better or more secure but the key is being interested in
how things work. Now with the knowledge of finding out how shit works comes
along the ability to place free calls and so on but those types of decisions are
up to the individual not the phreak scene.

// T-mobile - Get More... Than you're supposed to!
//
// by Lucky225 & Greyarea
// http://www.hexrev.com
After I 'moved' to Iowa, I decided to go with T-mobile as my cellular
provider. Like I do whenever I change carriers, I saw if I could break things.
T-mobile, as anyone might have guessed, was fairly easy. I have now found a way
to have completely unlimited calling for as low as $26.98/month.
Goto T-mobile.com or a T-mobile store and sign up for the Basic 60 whenever
minutes/500 weekend minutes for $19.99 per month. Then choose the option to add
Unlimited mobile-to-mobile calling for $6.99/month. This brings your monthly
total to $26.98/month before taxes.
Now you probably think you know where I'm going with this, a mobile-to-mobile
Caller ID spoofer right? Well read on. I've found a way to place OUTGOING
calls for free, as well as INCOMING.
// Outgoing Calls
Aparently, voicemail is considered a mobile-to-mobile call. T-mobile voicemail
(depending on what Mobile Voice Processor [MVP] you're using) will let you press
8 to return calls if the person who left you a message didn't block their caller
ID. The call is still considered mobile-to-mobile. I immediately started
thinking about spoofing my entire phone book into my voicemail, but then I had a
better idea. Just build an Asterisk dial out box, spoof the DID number into
your voicemail, then everytime you want to place a call out, log into your
voicemail and press 8 on the saved message with your Asterisk box DID phone
number. Now you can call out to anywhere and it wont waste any of your minutes.
// Incoming Calls
Now obviously this one should be easy for you to guess, just set up an
asterisk DID to give out as your cellphone and have asterisk call you from a
T-mobile phone number for it to show up as mobile-to-mobile. But what if you
could have one particular phone number that you know would always show up as
mobile-to-mobile? Well now you can, remember how calling voicemail is
mobile-to-mobile? Well aparently if you spoof 805-637-7243 (805-MESSAGE, the
national voicemail number) to your T-mobile cell phone it shows up as
mobile-to-mobile. Even stranger if you spoof 800-937-8997, T-mobile's customer
care, the call doesn't even show up in T-mobile's call logs!
// Privacy
Not only do you get the added benefit of all your incoming and outgoing calls
on T-mobile for free, but in the event of a Paris Hilton type hack, anyone
looking at your call detail records will only see incoming and outgoing calls
to or from voicemail!
// Disclaimer
T-mobile updates their MVPs(Mobile Voice Processors) all the time. This is
not guaranteed to work in your area. In Kansas, you don't even need to press 8
to call back the person in your voicemail, you can press 9 to call out to
anywhere, so not sure if Voicemail is mobile-to-mobile there, or if it's
mobile-to-mobile now that this article is probably sitting on the CFO's desk at
T-mobile. Also, I've noticed if I 3-way conference voicemail, it apears to not
show up as mobile-to-mobile unless I specifically dial 805-message instead of
holding down 1 or dial 123.
// Voicemail Bouncing
Since T-mobile's voicemail system is really insecure if the skip password
feature option is enabled, you can use other people's voicemail boxes to
'bounce' or divert your telephone calls. Now spoofing to 805-MESSAGE doesn't
work anymore, you would have to spoof to the particular MVP that handles the
T-mobile cellphone you are trying to spoof in to. (When you call 805-MESSAGE
from your cellphone, it is believed that the cell tower it's self actually
redirects you to the correct MVP which is why skip password works from your cell
but not when you spoof caller ID to it.) Most of the time the MVP can be found
in the cellular prefix with the last 4 digits being 9999. If you goto
telcodata.us you can lookup all the prefixes on the switch and scan out 9999
until you find the MVP for that cellphone. Once you have the MVP, you simply
spoof caller ID to it, and if skip password is enabled, you will be let in to
their voicemail box. If you spoof a number to call to the voicemail, you can
then spoof back into the MVP to retrieve the message and call that person back
from the MVP. The caller ID and Billing Telephone Number(BTN/ANI) will be that
of the cellphone, so any call traces will get traced to the cellphone of the
voicemail box you're bouncing through!

Laser Diode Operation and Application
ELCT 232
Unknown_Entity
4/27/05
Preface:
The following is by no means a comprehensive coverage of laser theory. This
article is intended to serve as an introduction for a laser project that I have
yet to publish, if you're on the binrev forums you may already know what i am
referring to. A complete and in depth analysis would require a 2nd or 3rd year
university physics course and more math than you could shake a stick at. All the
following information is true, this is really how lasers work but analyzing the
physics down to the most basic level is not necessary for an understanding how
lasers operate. The terms atoms, ions, and molecules are used loosely in the
context of this article to describe the action in a lasing medium, however the
actual particle in question depends on the specific medium used (He-Ne, Ruby,
Nd-YAG etc...).
General Laser Theory and Operation
Most lasers have three basic features in common. The first of which is a
lasing medium. The medium can be a solid, liquid, gas or semiconductor material.
The only requirement is that it must have a relatively low attenuation to any
light energy traveling within the medium. Secondly, there has to be a way to
"pump" energy into the lasing medium by optical, electrical or any other means.
The third requirement is an optically resonant cavity. The most common
arrangement is simply to place mirrors at the ends of the lasing medium so that
most of the energy escaping the medium is reflected back into the medium thus
achieving resonance. One mirror is 100% reflective while the output mirror
allows a small amount of light to pass through thus projecting a laser beam.
If all the previously mentioned requirements have been met then it is possible
for lasing to occur. Before any energy is pumped into the lasing medium the
atoms/ions in the medium are at a state of rest known as the ground state.
However by pumping energy into the medium the majority of the atoms/ions are
elevated one or more energy levels and are now in an excited state, this process
is known as a population inversion. When an atom/ion loses the energy that was
pumped into the medium it falls one or more energy levels at the same time
releasing a photon of light this is known as spontaneous emission. Spontaneous
emission happens at random as the atoms/ions lose their energy and fall back
towards the ground state. The photons released by spontaneous emission collide
with other atoms/ions in the medium and cause them fall back to lower energy
thus releasing a photon of their own. This process is known as stimulated
emission and is very similar to a chain reaction. Most of the photons/light
released are reflected back into the medium by the mirrors causing other
atoms/ions within the medium to drop to a lower energy level and release photons
as well. This process is called Stimulated emission. When stimulated emission
occurs eventually all of the atoms/ions that were pumped to a higher energy
level give up their energy and release photons as they return to the ground
state. This process produces a single pulse of light that is both monochrome
(containing only one wavelength of light) and coherent (all the light waves are
in phase with each other). This mode of operation produces only a single short
pulse of light. To produce a continuous beam (CW Mode) as most diode and gas
lasers do you need to pump energy into the cavity faster than the atoms/ions can
fall back to a lower state so that the population inversion is never depleted.
Laser Diode Types
The first diode lasers were developed in the early 1960's and were a miniature
version of the single optical cavity pulsed laser described above. They were
composed of a normal light emitting PN junction (LED) with an optical cavity
made of semiconductor crystal. As a result they were horribly inefficient and
could only be run in short pulses or risk melting the diode itself from
excessive heat. The beam shape of the output has an oval pattern that is common
among all types of edge emitting lasers. This early form of diode laser is
rarely used anymore.
Edge emitter type lasers are still used today however many advances have been
made to increase the efficiency of diode lasers. By replacing the single large
optical cavity with several layers of PN semiconductor forming multiple small
closely spaced cavities (usually no more than 5 layers) efficiency was greatly
improved. These same added layers also confine the free electron and hole pairs
to a concentrated area around the middle of the junction in the active region.
Due to the increased efficiency, less power is used to run the laser. Drive
requirements for this type of laser are very similar to that of standard LEDs
which is about 15-30mA DC. This means it can be ran continuously, rather than
just pulsed because overheating is no longer an issue. These types of diodes are
called heterojunction (multi junction) laser diodes and are the most common type
of diode lasers today.
The latest type of diode laser is called the Vertical Cavity Surface Emitting
Laser (VCSEL). VCSELs use the same concept of several smaller cavities to
increase efficiency however the number of layers can easily reach over 100. It
is different from most other types semiconductors lasers in that the laser beam
is amplified and emitted vertically (perpendicular to) rather than horizontally
(parallel with) the many semiconductor layers that make up the laser cavity.
VCSELs have many advantages over edge emitter type lasers. For example in the
manufacturing process there is greater degree of control of the qualities of
VCSEL type lasers because the final output properties can be altered by adding
more alternating PN layers or changing their thickness. Drive requirements for
VCSELs are only 1-2mA DC because the many PN layers cause it to have a rather
high impedance. This means they are far more efficient and have the potential
for faster switching speeds and data rates than edge emitter types. The optical
qualities (beam shape/astigmatism) of VCSELs are also superior to all other
semiconductor lasers, this is because the aperture and lasing cavity in VCSEL
lasers is round rather than oval like edge emitters
Diode Laser Applications
Diode lasers are used for a wide range of applications today ranging from a
simple laser pointer to high speed communications; however only a select few
will be discussed in detail here. The most familiar application of laser diodes
would be the simple laser pointer. The most basic laser pointer consists of only
a few simple parts such as a power source, switch and a series resistor to limit
the diode current to a safe level of 20mA or lower. The output of the laser
diode alone is not focused very well it is in the oval pattern of the edge
emitter. Therefore a minimum of two simple lenses are needed to focus the output
of the diode into the narrow beam that we are familiar with.
Diode lasers are also used as a pump source to feed higher power solid state
lasers. When laser diodes are used for this purpose they are often manufactured
as a "pump bar" unit. A pump bar consists of several diode lasers on a single IC
die. They can be stacked both horizontally and vertically to decrease the size
while increasing the power of the pump source. A common application of diode
laser pumps are handheld green lasers. They are often called Diode Pumped Solid
State lasers (DPSS). Handheld DPSS lasers use a single CW red laser diode to
pump a solid state laser cavity. The solid state cavity is what actually
generates the green wavelength of the output. Notice that the wavelength of the
pump input is not the same as the output. The energy levels traversed as well as
construction and composition of the solid state cavity determine the wavelength
of the output.
One application for laser diodes that is becoming increasingly popular is
their use in communication. Laser diodes and optics in general have a very high
bandwidth compared to more traditional means like transmission wires, radio
transmission or even microwave relay applications. Consider the wavelength of a
common red diode laser, it is about 640nM. If we wanted to calculate the
theoretical bandwidth we would need the frequency which is found by dividing the
velocity of light by the wavelength. This yields the equation
(300,000,000M/sec)/(640nM) resulting in a frequency of 4.74 x 10^14 or
474,000 GHz. If you were to divide this into separate voice channels each with a
bandwidth of 10kHz you would be able to fit 47 billion voice channels on a
single beam of light. This incredibly high bandwidth limit is the reason why
many industries such as the telephone and cable are making use of this
technology to enhance their networks.

Modding The Kodak Disposable Flash Camera
By ~Unknown_Entity~
Warning: This article assumes the reader has basic electronics knowledge and
soldering skills and is for informational/entertainment purposes only. Many of
the procedures in this article can cause bad things to happen if done
improperly. Capacitors can shock the crap out of you or explode like M-80's if
you exceed their rated voltage or reverse the polarity. Neither myself, nor the
publisher will be responsible for your use or misuse of the information
contained herein.
This article will cover the basics of modifying the Kodak disposable camera to
function as a high voltage current limited supply, or quite simply something
cool to shock the crap out of your friends with. The circuit functions as an
inverter that converts 1.5VDC to 330VDC or higher, not something that you'd want
to stick your tongue on. There are many things that can be made from this
circuit board including some power modifications that can generate over 600VDC
from a 1.5V battery, this article will only cover the simplest modification.
To start with you will need the following materials and tools (most are
available from RadioShack):
* Kodak Disposable Flash Camera
* Small Plastic Project Box (RS#: 270-283)
* 2 Panel Mount Banana Jacks
* 1 Single Pole On/Off Switch

If you want to exercise your SE skills and get some free camera circuit boards
try asking at places that develop pictures if you can have a few from the
disposable cameras people turn in to get developed. If you're of the school age
it would be best to say that you need the circuit board for a school project and
your instructor told you to ask around film developing places. If they ask about
the project itself, say you're using it to make a strobe light for an
electronics class.
Disassembly
Warning: Before continuing any further be aware that the capacitor inside may be
fully charged to 330V. You will need to remove the AA battery and discharge the
cap with a 1K ohm resistor before moving any further. The capacitor can be
discharged by placing a 1K ohm resistor across it's terminals. Just be sure to
use a pair of needle nose to hold the resistor or use wires and alligator clips
to discharge the cap with or else you may get shocked while doing so. Also do
not directly short out the cap at any time, doing so may destroy the circuit
board making it unusable.
Now that you have gathered all the tools and supplies previously mentioned we
can begin by liberating the circuit board from its plastic shell. Now would be a
good time to make note of the polarity on the AA battery. After the circuit
board is discharged and removed from the plastic case we can begin to remove
some unnecessary parts and add leads for our switches and battery. Your circuit
board should look similar to the one here. The parts that need to be removed are
all of the sheet metal brackets, pressure switch in the center of the board,
flash lens, flash tube and reflector. The brackets are soldered in at several
points; just make sure all points are desoldered before you start prying on the
board. This is where the good or at least decent soldering skills come into
play. Remove the parts shown in the picture while being careful not to damage
the board by overheating or prying on parts.
With the unnecessary parts removed your board should look similar to these.
Cutting the circuit board as shown is only necessary if you plan on putting this
in a project box to save space. You can also fold the capacitor over to help it
fit inside the project box, just make sure not to rip the leads out of the cap
while doing so. The next step is to solder wires to each point shown in the
picture. The negative (black) lead from the battery holder should be soldered
directly to the negative battery terminal on the board; all others should be
connected as shown. The 1K ohm resistor serves to protect from a direct short
across the terminals, which may damage or destroy the circuit.
Final Assembly
I will leave the final assembly to the reader's discretion, but I will offer
some tips and suggestions. The project box listed at the beginning of this
article and N type battery holder fit perfectly for a project of this size. If
you plan to fit this inside a project box put heat shrink tubing around the
resistor, coat all switch terminals and the bottom of the circuit board with hot
melted glue, you don't want this to blow up or shock someone unintentionally.
If you use the project box listed you will have to remove the two standoffs
used to hold the board included with the box. Finally, the hot glue gun is your
friend; you can use it to secure the board and battery holder to the box.
Safety and Common Sense
A charged high voltage capacitor of sufficient size can kill you under the
proper conditions; they are not something to be taken lightly. If you plan to
use this as a small high voltage supply you can keep, change or omit entirely
the 1K ohm resistor in series with the cap. However if you plan to use this to
zap people with you will need to change the 1K ohm resistor to a higher value.
The purpose of the resistor is to limit the maximum current that the cap can
output. It is current flowing through your body that causes you to feel an
electric shock. Therefore the more current that passes through you the more
painful the shock received. The only thing obstructing the current flow is the
resistor you add to the circuit and if you were to touch the terminals, your own
body's resistance. Some other factors that affect the severity of a shock are
contact area (touching a flat piece of metal vs. a sharp point), contact points
(two fingers on the same hand vs. arm to arm). Under normal conditions using the
1K ohm resistor if you were to touch the HV terminals you would get a nasty
shock. This circuit with the 1K ohm resistor hurts worse than the 120V wiring in
your house. You can reduce the severity of the shock by replacing the 1K ohm
resistor with a higher resistance.
The resistance of the human body varies greatly depending on many conditions
and in this case it is best to err on the side of caution when choosing a
resistor value. You can use Ohms Law to calculate what the maximum current is
for a given resistance. In other words by choosing the proper resistance we can
limit the maximum current that the cap can output regardless of what other
resistance (or body part) is placed across the output terminals. The following
formulas hold true where V is the 330V stored in the cap, R is the resistor
value in ohms and the result I is current in Amps.
I= (V/R) V= (I*R) R= (V/I) Ex. (330V/.010A)= 33,000 ohms
Let's assume we wanted to limit the maximum current our cap can output to
.010A or 10mA. We would use the formula that is set equal to the unknown R where
V is the 330V and I is the .010A limit we wish to have. Solving for the equation
yields the value of the resistor needed to limit the current to .010A. Of course
if you were to touch the terminals in our example the current that would pass
through you will always be less than what we calculated because your body does
have a certain amount of resistance. Using this method to set the maximum
current more or less serves as a cover your ass policy? so don't say I didn't
warn you. The following numbers are for hand to hand and hand to foot contact
but the effects will be similar for other contact points.
Current Reaction
Below .001 Amps Generally not perceptible
.001 Amps Faint Tingle
.005 Amps Slight shock felt. Not painful but disturbing.
Average individual can let go. Strong involuntary
reactions can lead to other injuries.
.009 to .030 Amps The freezing current or "let go" range. If extensor
muscles are excited by shock, the person may be
thrown away from the power source. Individuals
cannot let go. Strong involuntary reactions can
lead to other injuries.
.050 to .150 Amps Extreme pain, respiratory arrest, severe muscle
reactions. Death is possible.
1.0 to 4.3 Amps Rhythmic pumping action of the heart ceases.
Muscular contraction and nerve damage occur; death
is likely.
10 Amps Cardiac arrest, severe burns, death is probable.
Completed Projects
The following picture shows two different examples that I have built during
the course of writing this article. The first is the basic one that was used
throughout the article. The high voltage output is fed through two banana jacks
mounted to the box. The second unit pictured is my favorite mod and should
provide endless hours of entertainment. The circuit is the same as the basic mod
except that there is no switch to turn the unit off, it only has the charge
flash switch. Secondly the high voltage outputs are wired directly to two
brushed aluminum plates on opposite sides of the plastic case. All you do is hit
the charge flash switch and set the box down for someone to pick up. Most people
are like "Ooh? Shiny Object" and pick it up, if not tape a $1 bill to it. When
they touch both plates at the same time they get zapped and you get a good
laugh. I have also included the schematic for the unmodified Kodak Max
disposable camera. The circuit for the regular Kodak and the Kodak Max should be
very similar if not identical.

Meditation: A Definitive Study
When you look up meditation on the internet you're bound to find a multitude
of links, each with a different view of what constitutes meditation and its
various benefits. Turning to the general public for personal, experiential
input, you are bound to have similar results: a multiplicity of various
techniques and experiences. Among this barrage of often conflicting information
there is a tendency for one to get lost, confused, misled and eventually to
write the whole meditation thing off as some hokey, modern fad. Fortunately for
the seeker of Truth, there is a common thread to all substantive approaches to
meditation: Clarity. We all have some sort of inner dialogue that is constantly
questioning everything it can get its philosophical feelers on. The questions
are boundless in supply and they demand answers for which people have been
searching for since the beginning of thought/time (same thing). They are
questions like "Why?...",(did I/He/ She make the choice to do that?), "How?",
(can I change this or that about myself/ the outside world?), "Where?", (did I
and my thoughts come from? Can I keep them?), "What?", (in the hell does he mean
by ?thought/time (same thing)'?). More often than not, the answers we find to
these questions and the infinite others like them, are superficial by a long
shot, leaving our thirst wide open and overwhelmed by the 10,000 answers that
popped up in your search engine when you looked up "Meditation". It is the
process of meditation?looking inward, composed in stillness?that brings
boundless clarity and sheds unfettered light on one's inner dialogue.
Eventually, the clarity and light are everywhere you look and a greater general
understanding awakens.
No matter which of the various techniques you try, the essence of bringing
about clarity in any situation is stillness. Looking into the depths of the
clearest water, one's view is distorted by raindrops rippling across the surface
and stirring the sediment below. Only when the rain subsides, the wind calms,
the dust finally collects at the bottom of the pond, only then can we once again
clearly observe the life beneath the surface. The same is always true of trying
to observe objects in action; details become blurred and there is a broad avenue
of interpretation, no matter what it is you are trying to see. Race cars
zooming by look like intangible blurs of color, a diving bird of prey could be
an Osprey, Eagle or Falcon, a flock of thoughts mingling with the void could be
jealousy, admiration, greed, ambition, insecurity or passion. Until both the
subject and its vigilant caretaker are at rest, the details regarding either one
(subject or object) are uncertain. When beginning to observe the mind, it is
often tempting to accept the apparent stillness found in concentration or focus
practice. This situation is like looking at the surface of a pond on a still
day and assuming that your view beneath the surface is ultimately clear.
However, upon further investigation, you may find myriad activities beneath the
surface that muddle the view. It is the same when first observing the mind; one
will feel an overarching tranquility when first practicing meditation, but as
the focus moves deeper into the consciousness, the turmoil beneath the surface
becomes evident and the real work of stilling the mind begins.
After constant and vigilant practice, after reconciling one's inner dialogue,
a deeper personal understanding begins to emerge along with a new level of
clarity and transparency in one's view of the outside world. The difference
between self and other begins to lose its significance and the inwardly applied
understanding begins to be more easily applied outwardly as well. It is here
that compassion is built and one can begin to learn how to motivate and share
insight with others. Unfortunately, not all of the ?others' will be open or
able to receive or understand the unfamiliar type of insight found in meditation
which is more spontaneously amorphous and intuitive than the linear and rational
types of problem solving familiar to most people. Meditative problem solving
works in a reversed progression to logical deductive reasoning. In the
intuitive approach, the solution becomes evident first by stopping thought
altogether, then the how and why of the solution can be reconciled if necessary.
Typical problem solving works just the opposite way?that is, by asking repeated
?how's and ?why's and eventually (hopefully) reaching a solution. The
meditative or intuitive approach has learned that thought itself is unclear by
nature, that words and tools of logic move only toward conditional truth and
cannot ever find absolute truth. On the contrary, in transcending rational
thought and its logic tools (words, signs and symbols), intuitive or meditative
?thought' is a mechanism designed by the creator for grasping the ultimate or
absolute truth.
When one is enshrined in stillness, he sits with the nameless
Gods of every religion. Various cultures use various localized symbols and
ideas to express their personal value systems into modes of religious thought,
usually with the intention of pointing the way toward what they have experienced
as the penultimate reality. However, in their truest form, all religious
symbols, ideas, and ideologies point to the same space beyond space; a place
called God that exists within each of us and that is reached by the most
difficult road there is to navigate: the road to silent composure in stillness.
Defining meditation is, in all truthfulness, an impossible task; in action,
meditation is immobile, to speak of meditation is silence, to write about
meditation is to leave behind an empty page. Truth is most often sought as
something definitive, tangible; but truth is not a linear, logical process of
reasoning. If it were that simple, we would have surely stumbled across it
somewhere in our thousands of years of searching the human mind. In a sense,
all of those links you looked up on meditation (including this one) are equally
valid and invalid. Practice is the only way to reach a definitive understanding
(or truth) of meditation or anything else for that matter. In fact, according
to some of the most devout scholars of truth, the true definition of meditation
is as simple as "sitting practice" or "just sitting". The only advice I can
offer someone interested in finding out what meditation really is: Be still, and
the truth shall set you free.

New Hacker Manifesto - draft 0.1
Goat
In any society, there will be those who need rules to tell them the obvious.
"Thou shalt not kill" reflects the tendency of most people to be unable to tell
the difference between a justifiable killing and one that is not. All killings
appear the same, just like all computer break-ins have the same appearance, thus
are dubbed "unethical" and "illegal".
Life is not as simple as it seems. When an individual reaches a certain stage
of proficiency, he or she either gets sidetracked by quick gratification, such
as theft, or rises to a higher proficiency because the love of learning and joy
in the powers granted by it drives them forward. Such is the case with hacking,
where those who have learned a few trivial skills become destructive, but those
who are constantly reverent toward their task become constructive, even if they
must use some destruction toward that end.
Some try to divide the hacking community by ethics, as in "white hat"
(ethical) and "black hat" (criminal) hackers, but the reality is that there is
another category for those who hack because they appreciate technology and like
pushing it to do things that otherwise could not be done. They do not get
sidetracked by appearance such as theft or vandalism, but use technology toward
the end of making technology better.
This is comparable to the state of a knight in ancient cultures. The knight
was above all laws made for normal people, as he was trusted to do what was
right according to the whole of civilization and nature, even if it meant that
some unfortunate would be deprived of life, liberty or happiness. The knight did
what was necessary to push his surroundings toward a higher state of order,
avoiding the entropy caused by those who were doomed to the world of appearance
and could thus see only binaries: living/dying, money/poverty, right/wrong. The
knight transcended these boundaries and "hacked" his surroundings by pushing
them to do things that otherwise could not be done, replacing previous designs
with better ones.
Design and logical structure are the "hidden world" in which hackers,
philosophers, artists and knights operate. The world of appearance deals with
physical objects, but not the underlying structure which connects them.
Similarly, users see the appearance which computers are programmed to show them,
but have no idea of the workings of networks and operating systems. A knight
must know how to manipulate this hidden world, and must have the moral strength
to be destructive only when it is constructive to do so.
Hacking today is far different than it was twenty years ago. During the
formative days of hacker culture, computing resources were scarce. Most people
used 1-10 MHz machines and could not get access to the instructive operating
systems like UNIX and VMS unless they hacked into larger machines for that
access. Today, desktop UNIX-like operating systems are plentiful, and network
access is a nominal monthly fee. One reason that hacking has appeared to
stagnate is that it has not re-invented itself to address this new reality.
When most people think of "hackers," they imagine the black hat criminal
element that steals credit cards and identities. White hat hackers have become
like adult chaperones at a teenage sex party, wagging disapproving fingers but
having little overall effect. Since it is no longer necessary to hack machines
for access, hacking must redefine itself according to its core principle:
understanding the structure behind the appearances of computing, and to like a
good knight, always reinvent the design of the underlying layers so that
technology and society move toward higher degrees of organization.
In this capacity hackers are a hedge against entropy, or the state of disorder
that occurs over time and is exacerbated by people acting on appearance as if it
were structure, causing them to manipulate form but not function. Most human
technologies are flawed and operate poorly, subjecting the user to untold
problems, much as governments and ideas are flawed and cause similar confusions.
The hacker of today must unite philosophy, computing and politics in a quest to
find better orders and to defeat entropy by understanding how things work, and
not what pleasing appearances will sell to a credulous consumer base.
Hackers as knights represent a potential force of change in our society. We
can see where technology could be organized better, so that without inventing a
new type of computer we can make older computers better; hackers can prank
society to point out its illusions and contradictions. Because we have the
skills to do this, we are necessarily above the law, and must use that status to
achieve the kind of reordering of civilization that normal people cannot. Should
we choose to accept the role with all of its responsibilities, we are the
knights who can redesign industrial society into something that serves humans
instead of imprisoning them in a world of appearance.

POPULARITY IS FAILURE
"But that's what everyone wants!" -- For too long, humanity has been ruled by
popular opinion. Most people are gawking fools who desire the lowest common
denominator in any situation. You see them in offices, doing menial tasks that
must have been invented for them because they can do nothing else. In every
election they vote some smirking, condescending mall-culture moron into office.
At stores, they agitate for dumber cheaper products to replace quality. They
murdered culture because they didn't understand it. They demanded pluralism so
no one could criticize their inane "lifestyle choices." We are the consequence:
a separate culture within that rejects the illusory world of "what everyone
wants." We will hack your networks, reprogram your philosophy and decode your
values. We are a civilization where truth is more important than popularity.
You are a failed past. We are the future.
YOU ARE OBSOLETE
