A class for manipulating integer value ranges.
The idea is to have a representation of common sets of values that a varnode might take on in analysis so that the representation can be manipulated symbolically to some extent. The representation is a circular range (determined by a half-open interval [left,right)), over the integers mod 2^n, where mask = 2^n-1. The range can support a step, if some of the least significant bits of the mask are set to zero.
The class then can
| CircleRange::CircleRange | ( | uintb | lft, |
| uintb | rgt, | ||
| int4 | size, | ||
| int4 | stp | ||
| ) |
Construct given specific boundaries.
Give specific left/right boundaries and step information. The first element in the set is given left boundary. The sequence then proceeds by the given step up to (but not including) the given right boundary. Care should be taken to make sure the remainders of the left and right boundaries modulo the step are equal.
| lft | is the left boundary of the range |
| rgt | is the right boundary of the range |
| size | is the domain size in bytes (1,2,4,8,..) |
| stp | is the desired step (1,2,4,8,..) |
| CircleRange::CircleRange | ( | bool | val | ) |
Construct a boolean range.
The range contains only a single integer, 0 or 1, depending on the boolean parameter.
| val | is the boolean parameter |
| CircleRange::CircleRange | ( | uintb | val, |
| int4 | size | ||
| ) |
Construct range with single value.
A size specifies the number of bytes (*8 to get number of bits) in the mask. The stride is assumed to be 1.
| val | is is the single value |
| size | is the size of the mask in bytes |
| int4 CircleRange::circleUnion | ( | const CircleRange & | op2 | ) |
Union two ranges.
Set this to the union of this and op2 as a single interval. Return 0 if the result is valid. Return 2 if the union is two pieces. If result is not zero, this is not modified.
| op2 | is the range to union with |
| bool CircleRange::contains | ( | const CircleRange & | op2 | ) | const |
Check containment of another range in this.
| op2 | is the specific range to test for containment. |
| bool CircleRange::contains | ( | uintb | val | ) | const |
Check containment of a specific integer.
Check if a specific integer is a member of this range.
| val | is the specific integer |
| int4 CircleRange::getMaxInfo | ( | void | ) | const |
Get maximum information content of range.
In this context, the information content of a value is the index (+1) of the most significant non-zero bit (of the absolute value). This routine returns the maximum information across all values in the range.
| uintb CircleRange::getSize | ( | void | ) | const |
Get the size of this range.
| int4 CircleRange::intersect | ( | const CircleRange & | op2 | ) |
Intersect this with another range.
Set this to the intersection of this and op2 as a single interval if possible. Return 0 if the result is valid Return 2 if the intersection is two pieces If result is not zero, this is not modified
| op2 | is the second range |
| int4 CircleRange::invert | ( | void | ) |
Convert to complementary range.
Convert range to its complement. The step is automatically converted to 1 first.
| bool CircleRange::minimalContainer | ( | const CircleRange & | op2, |
| int4 | maxStep | ||
| ) |
Construct minimal range that contains both this and another range.
Turn this into a range that contains both the original range and the other given range. The resulting range may contain values that were in neither of the original ranges (not a strict union). But the number of added values will be minimal. This method will create a range with step if the input ranges hold single values and the distance between them is a power of 2 and less or equal than a given bound.
| op2 | is the other given range to combine with this |
| maxStep | is the step bound that can be induced for a container with two singles |
|
inline |
Equals operator.
| op2 | is the range to compare this to |
| void CircleRange::printRaw | ( | ostream & | s | ) | const |
Write a text representation of this to stream.
| s | is the stream to write to |
Pull-back this range through given PcodeOp.
The pull-back is performed through a given p-code op and set this to the resulting range (if possible). If there is a single unknown input, and the set of values for this input that cause the output of op to fall into this form a range, then set this to the range (the "pullBack") and return the unknown varnode. Return null otherwise.
We may know something about the input varnode in the form of its NZMASK, which can further restrict the range we return. If usenzmask is true, and NZMASK forms a range, intersect this with the result.
If there is Symbol markup on any constant passed into the op, pass that information back.
| op | is the given PcodeOp |
| constMarkup | is the reference for passing back the constant relevant to the pull-back |
| usenzmask | specifies whether to use the NZMASK |

| opc | is the OpCode to pull the range back through |
| val | is the constant value of the other input parameter (if present) |

| in1 | is the first given input range |
| in2 | is the second given input range |
| inSize | is the storage space in bytes for the input |
| outSize | is the storage space in bytes for the output |
| maxStep | is the maximum to allow step to grow via multiplication |
| bool CircleRange::pushForwardTrinary | ( | OpCode | opc, |
| const CircleRange & | in1, | ||
| const CircleRange & | in2, | ||
| const CircleRange & | in3, | ||
| int4 | inSize, | ||
| int4 | outSize, | ||
| int4 | maxStep | ||
| ) |
Push this range forward through a trinary operation.

| bool CircleRange::setNZMask | ( | uintb | nzmask, |
| int4 | size | ||
| ) |
Set the range based on a putative mask.
Try to create a range given a value that is not necessarily a valid mask. If the mask is valid, range is set to all possible values that whose non-zero bits are contained in the mask. If the mask is invalid, this range is not modified.

An excerpt of Teaching Machines is in The MIT Press Reader: "The Engineered Student: On B. F. Skinner’s Teaching Machine."
"The story of teaching machines is deeply intertwined with Skinner’s psycho-technologies, which laid a foundation from which education technology has never entirely broken."


One of the most magnificent structures in the computer science world is the function.
Functions (sometimes called procedures) are mini-programs that you can use over and over inside of your bigger program.
Functions are pieces of code that you can call over and over again.
Functions are at the heart of JavaScript. They let you write code that you can quickly use again and again.
Remember! Our song exercise at the beginning of class? The chorus acts like a function that you can call over and over when you want the singer to sing those lyrics. What are some real life functions?
The following is how you declare a function:
function functionName() {
//code you want to repeat
}
Name a function like you name a variable. Best practices:
Function names cannot start with a number.
Everything within the curly braces is the code block.
The code in the code block only runs when the function is activated. How do we run the code block in myGreeting?
function myGreeting() {
alert("Good morning!");
}
To activate our code block, we need to call the function housing the code block. You call the function like so:
myGreeting();
The parentheses ()
are what actually call the myGreeting function. Parentheses ()
are very important!
In summary, functions are re-usable collections of statements.
First, declare the function:
function sayMyName() {
console.log('Hi Jessica!');
}
Then call it (as many times as you want):
sayMyName();
//Create your function first
function alertRandom() {
//create a new random number each time the function is run
let randomNumber = Math.floor(Math.random()*6)+1;
alert(randomNumber);
}
//calling the function
alertRandom();
function alertRandom() {
let randomNumber = Math.floor(Math.random()*6)+1;
alert(randomNumber);
}
alertRandom();
alertRandom();
alertRandom();
alertRandom();
var alertRandom = function() {
let randomNumber = Math.floor(Math.random()*6)+1;
alert(randomNumber);
};
Which of the following describes a function?
Which of the following code snippets correctly shows how to create a function named sayHello
which opens an alert dialog with the string "Hello" in it?
function sayHello {
alert("Hello");
}
function sayHello (
alert("Hello");
)
function sayHello() {
alert("Hello");
}
var function=sayHello() {
alert("Hello");
}
Bad:
function addNumbers() {return num1 + num2;}
Good:
function addNumbers() {
return num1 + num2;
}
Up until this point, our programs have been running from top to bottom in HTML and CSS.
Functions allow the browser interpreter to store information to be sure that proper code is being called depending on the contents of the function.
Many developers write their functions at the beginning of their code, so all of them are grouped together.
Functions don't just run JavaScript statements. They can also return values that you can use elsewhere in a program.
Functions can also give something back when they finish. This is called returning a value.
function goToCoffeeShop() {
return "Espresso is on the way";
}
The value that is returned by the function can then be used in your program.
‘return’ing something in JavaScript is very useful
You can use its values for many other parts of your program. Examples: display items on your website, do calculations, etc.
Return statements should be the last thing in the code block of a function, because they immediately exit the function.
The return
keyword returns a value to whoever calls the function (and exits the function):
function addNumbers() {
var num1 = prompt("What is your favorite number?");
var num2 = prompt("What is your second favorite number?");
let result = Number(num1) + Number(num2);
return result; // Anything after this line won't be executed
}
var sum = addNumbers();
After the code below runs, what value is stored in the variable dayOfWeek
?
function getDay() {
return "Monday";
alert("Calculating day");
return "Friday";
}
var dayOfWeek = getDay();
What is the return
value of running a load of laundry?
How is this different from using console.log()
?
1. Create a function named getYear
.
2. Inside the function's code block add this line of code:
var year = new Date().getFullYear();
This creates a new variable and stores the current year in it.
3. Add a statement that returns the variable.
4. Call the getYear
function & store the returned value in a new variable named yearToday
.
You can give information to a function to change how it works.
Coffee shop example
JavaScript functions can also accept information called an argument, which you send to the function.
The argument is stored in a variable called a parameter that you can use inside the function.
function myFunction(parameter) {
//code block
}
Parameters are variables.
Passing an argument to a function
function goToTheCoffeeShop(drink) {
alert(drink + " is on the way!");
}
goToTheCoffeeShop("Espresso");
You can pass different values and get different results!
You can also have multiple arguments in a function. More on that very soon!
In our example, let’s say I also want something to eat.
function goToTheCoffeeShop(drink, pastry) {
alert(drink + "and " + pastry + " are on the way!");
}
goToTheCoffeeShop("Espresso", "scone");
You can pass different values and get different results!
You can also have multiple arguments in a function.
You want to add no more than 4 or 5 arguments to a function. This can get tedious.
In JS Bin, let’s create a function to calculate the area of a rectangle.
Functions can accept any number of named arguments:
function sayMyName(name) {
console.log('Hi, ' + name);
}
sayMyName('Claire');
sayMyName('Testy McTesterFace');
function addNumbers(num1, num2) {
let result = num1 + num2;
console.log(result);
}
addNumbers(7, 21);
addNumbers(3, 10);
You can also pass variables:
var number = 10;
addNumbers(number, 2);
addNumbers(number, 4);
var nameImprover = function(name, adj) {
return 'Col ' + name + ' Mc' + adj + ' pants';
};
var nameImprover = function(name, adj) {
return 'Col ' + name + ' Mc' + adj + ' pants';
};
var nameLogger = function(name, adj) {
let newName = 'Col ' + name + ' Mc' + adj + ' pants';
console.log(newName);
};
Read here for more on the return keyword
Read here for more on the console.log() method
var addTwo = function(a, b) {
console.log(a,b); // logs 3,10
return a + b;
};
addTwo(3, 10); // 13
Why would a developer use the console.log()
method in the addTwo
function in the development phase?
Why would a developer remove the console.log()
method in the addTwo
function for the production phase?
JavaScript can handle multiple functions.
Each function acts like its own individual universe.
The variables created in one universe do not interact with the variables created in another universe or another function.
This means that functions are a wonderful tool to use when coding with security in mind.
function greeting() {
let person= "Lilah";
alert(person);
}
var person = "George";
greeting();
alert(person);
function greeting() {
let person = "Lilah";
alert(person);
}
var person = "George"
greeting();
alert(person);
LOCAL: A variable declared in a function only lives inside that function and cannot be accessed or changed outside of that function and has therefore local scope.
GLOBAL: Any variables you create in a script that are not contained in a function are in this bigger universe called the global scope.
**All functions can access the global scope.
The word “scope” refers to where a variable is declared.
As you create more complex programs, you'll end up adding multiple functions to your scripts.
It's possible, even likely, that a function defines and uses the same name as a variable used elsewhere in your script.
You might write some JavaScript with a variable named “width”, but also have a function named computeArea
that also has a width
variable inside it. More on this later.
var width = 6;
var computeArea = function(width) {
return width * width;
};
1. You can use the var
keyword to declare variables outside of functions. These global variables can be used by other functions and variables.
2. You can use the let
keyword to declare variables inside of functions. These local variables are block scoped.
3. You can use the const
keyword to declare variables whose values cannot be reassigned. These will often be global variables.
A variable with "local" scope:
function addNumbers(num1, num2) {
let localResult = num1 + num2;
console.log("The local result is: " + localResult);
}
addNumbers(5, 7);
console.log(localResult);
A variable with "global" scope:
var globalResult;
function addNumbers(num1, num2) {
globalResult = num1 + num2;
console.log("The global result is: " + globalResult);
}
addNumbers(5, 7);
console.log(globalResult);
Why pay a fortune teller when you can just program one yourself?
tellFortune
that:Calculate Your Age!
calculateAge
that:
var divideByThree = function(number) {
let val = number / 3;
console.log(val);
};
How would you call this function so that 3 is logged to the console?
var greeting = function(name) {
console.log("Great to see you," + " " + name + "!");
};
How would you call this function so that “Great to see you, Grace Hopper!” is logged to the console?
var foodDemand = function(food) {
console.log("I want to eat" + " " + food + ".");
};
How would you call this function so that “I want to eat Chinese food.” is logged to the console?
var coffeeCost = function(cost) {
let total = cost * 5;
console.log(total);
}
Jessica drinks five cups of coffee a day. How would you call this function if the cost of her coffee is $3?
Given the code below, what appears in the alert dialogue when this program runs?
var name = "Wonder Woman";
function setName() {
let name = "Diana Prince";
}
setName();
alert(name);

This is roughly the speech I
gave as a keynote address at
DjangoCon 2009
in Portland.
I’ve been programming Python
web software for quite a while now.
I considered coming here and talked
about WSGI, standards,
cross-framework integration, etc.,
but I decided I wanted to come up
here and talk to you as compatriots,
as fellow open source programmers.
Over the past year or so I have been
thinking a lot about politics. Not
electoral politics per se, or the
geopolitical situation, but the
question of the meaning of what we
are doing. Maybe it is some sort of
programmer midlife crisis: why am I
doing what I’m doing, and why
does it matter? And also I have been
thinking a lot about open source
— what this thing that
we’re doing means in the
larger context. Are we just
engineers? Is there some sort of
movement? If so, what is that
movement? Especially as open source
has become more popular, the sense
of a movement seems to dwindle. It
felt like a movement 10 years ago,
but not as much today. Why should
this happen? Why now, in the midst
of success does open source seem
less politically relevant than it
did 10 years ago?
I’m also speaking somewhat to
Django specifically, as I think it
is one of the communities with a bit
more resistance to the idea of the
politics of code. The Django
philosophy is more: the value of
this code is the value of what you
do with it. I’m not here to
criticize this perspective, but to
think about how we can find meaning
without relying on the traditional
free software ideas. To see if
there’s something here that
isn’t described yet.
I’d like to start with a quick
history of free and open source
software. My own start was in
highschool where I was taking a
class in which we all used Emacs.
This was my first introduction to
any real sort of programming
environment, to Unix, to a text
editor that was anything to talk
about. At the time Emacs would say
at startup "to learn more about
the GNU project hit Control-H
Control-P" — because of
course you need a keyboard shortcut
to get to a philosophy statement
about an editor. So one day I hit
Control-H Control-P. I was expecting
to see some sort of About Message,
or if you remember the software of
the times maybe something about
Shareware, or even "if you
really like this software, consider
giving to the Red Cross." But
instead I came upon the GNU
Manifesto.
GNU Manifesto
I’d like to read a couple
quotes from the
GNU Manifesto. There are more
modern descriptions of
GNU, but this is one of the first
documents describing the project
and its mission, written by
Richard Stallman. Let me quote
the section "Why I Must
Write GNU":
"I consider that the
golden rule requires that if
I like a program I must
share it with other people
who like it. Software
sellers want to divide the
users and conquer them,
making each user agree not
to share with others. I
refuse to break solidarity
with other users in this
way. [it continues...]
"So that I can continue
to use computers without
dishonor, I have decided to
put together a sufficient
body of free software so
that I will be able to get
along without any software
that is not free."
[later it goes on...]
"The fundamental act of
friendship among programmers
is the sharing of programs;
marketing arrangements now
typically used essentially
forbid programmers to treat
others as friends. The
purchaser of software must
choose between friendship
and obeying the law.
Naturally, many decide that
friendship is more
important. But those who
believe in law often do not
feel at ease with either
choice. They become cynical
and think that programming
is just a way of making
money."
When I read this statement I was
immediate head-over-heels in
love with this concept. As a
teenager, thinking about
programming, thinking about the
world, having a statement that
was so intellectually aggressive
was exciting. It didn’t
ask: "how wrong is piracy
really", or "why are
our kids doing this", but
it asked "is piracy a moral
imperative" —
that’s the kind of
aggressive question that feels
revolutionary and passionate.
Let me go over one of the lines
that I think exemplifies this:
"I consider that the
golden rule requires that if
I like a program I must
share it with other people
who like it."
It wasn’t saying: what are
we not allowed to do, nor did it
talk about some kind of societal
injustice. It didn’t talk
about the meaning of actions or
their long-term effects. Instead
it asked: what must we do, not
as a society, not in service of
some end, but what are we called
upon to do as an
individual,
right now, in service
of the people we call friends.
It didn’t allude to any
sociological explanation,
natural selection, economics;
there is just the golden rule,
the most basic tenant of moral
thought.
Free Software vs. Open Source
When I first encountered free
software, I suppose about 15
years ago, this was during one
of the more difficult periods of
its evolution. It was past the
initial excitement, the initial
optimism that the project would
take only a couple years to
reach parity with closed-source
Unix, it was before it was clear
how the project would move
forward. Linux was young and
seemed to be largely off the
radar of Richard Stallman and
other GNU advocates, and they
were struggling to fill in final
key pieces, things like a
kernel, widgets, and they
hadn’t even thought about
entirely new things like
browsers.
The message that came through
from that period is not the
message I wish came through. The
message I wish came through was
that message from the GNU
Manifesto, that spirit of a new
sense of duty and ability. When
people talk about Richard
Stallman and the Free Software
Foundation and the GNU Project,
they’ll often point to the
GNU General Public License as
the most important contribution
— the GPL. I’m sure
you all know something about it.
Of course the core concept there
is the idea of copyleft. Not
only will the software be open,
but it’s takes the implied
perspective that the principles
of freedom are rights —
that unfortunately the world is
not wise enough to see that use,
distribution, and modification
are rights; but the GPL still
asserts that these
are your rights. When
you become one of us, when you
participate in the freedoms this
license grants you, when you use
the GPL, there is encoded in the
license a support for this sense
of the natural right of free
software. We, GNU, can’t
encode that for the world, but
for the software that we write
these rights are inalienable.
But as I said those were
difficult times. There was a
great deal of pressure. People
were trying to understand what
open source meant. People still
struggle with questions: how
would an economy function, how
would a programmer get a job, if
this is as successful as people
hoped will we all just be out of
jobs? Other questions were: who
will write the software that no
one wants to write? How can I,
embedded in a situation where I
can’t actually use only
free software — remember
at this time there was no way to
use completely free software
— how can I assert a duty
to do something that is not
possible? How can I be useful
unless I interface with all
these proprietary things? If I
deal with companies which
aren’t comfortable with
open source software, then what?
After all, open source seemed
only barely plausible at this
time. It was not an easy
argument to make.
And all this was before the term
"open source" really
took hold as a distinct idea.
That itself is an interesting
story. There was a time during
this marketing period when there
arose a kind of terminology
divide — free software vs.
open source software. The
terminology divide was that the
"free" in free
software implied you
couldn’t charge anything,
that made people think about
price, might even imply
cheapness. Open source directly
refers to programming, uses the
feel-good term "open",
and doesn’t sound too
revolutionary. But besides that
there was also a substantial
philosophical difference about
the value of the software
itself.
So there was a difference in how
things were going to be pitched,
but also a difference in what
people thought the general value
of this project was. From GNU
and Richard Stallman there was
the notion that this was right
because it was right; it was a
moral imperative. The virtue of
what we build is in its freedom;
if it is also technically
superior then that’s
great, but it is not how we
should judge our success. We
were giving people
self-determination: programmer
self-determination, user
self-determination… on the
open source side the argument
was that this is a good way to
create software. Programmers
working together can do better
work. With many eyes all bugs
are shallow. All working
together, we’ll work
faster, you get the benefit of
free contributions from all
sorts of people. People were
clamouring to get all these
proprietary companies with
failing software products to
open source their software;
miracles will occur! What you
thought was useless will regain
value! You’ll reattain
relevance!
The open source and free
software philosophical divide:
on one side practical concerns,
on the other moral. And this is
what I want to talk about later:
can we find a moral argument for
these practical concerns?
The basic free/open disagreement
continues in debates over
licenses: the GPL vs. the BSD
and other permissive licenses.
If you read the
GPL
it talks a great deal about
philosophy; if you read the
BSD license
it’s really just some
disclaimers and basic
instructions, and the one line:
"Redistribution and use in
source and binary forms, with or
without modification, are
permitted." It
doesn’t say why
you’ve received this
software, or any philosophy
about rights and freedoms, or
even encourage you to use the
same license on your own
software. An engineer’s
license.
So these two licenses in many
ways became a focus and
definition of free and open
source software. If you look at
the
Open Source Initiative, which has served to define
what "open source"
means, it is basically just a
list of approved
licenses. If you use one of those
licenses, the software is open
source, if not then it is
closed.
I think this is disappointing,
because licenses are just law,
and law is not very interesting.
A law tells you what you
shouldn’t do, it
doesn’t tell you what you
should do. When both sides are
talking about freedom, the
licenses just define freedom as
the lack of certain
restrictions. Take away those
restrictions and voila, you are
free… as though we are all
just bundles of freedom waiting
to be released.
Self-Definitions
With licenses we have a negative
definition of our community.
Either license you choose, the
license feels like a reaction
against closed source software.
If you can imagine a world in
which there was no copyright,
where our platforms were all
setup to distribute source code
in modifiable forms, where
everything was open and
everything was free, then none
of these licenses would matter.
No one would be compelled to
create the GPL in such a world;
we wouldn’t advocate for
copyright just so we can secure
people’s freedoms. In that
kind of world all this licensing
disappears. And this isn’t
even so weird a world. You can
pretend there’s no
copyright now. Maybe you have to
reverse-engineer some stuff.
There’s lots of places in
the world where no one really
gives a damn about copyright.
But those places don’t
feel open source to me, they
don’t feel that more free.
We aren’t made unfree just
by legal restrictions; freedom
is something we have to actively
grasp.
I don’t think what we do
is predicated on copyright.
Indeed, many projects are
comfortable with an entirely
confused copyright ownership.
This causes very few problems. A
focus on licensing makes us into
a reaction against proprietary
software, where we allow
proprietary software and its
makers to define what it means
to be us.
This concerns me because it
isn’t just about formal
definitions and terminology.
When I say
what do I do, I say I
am an open source programmer.
That’s not just an
attribute, like saying that my
hair is brown. Open source is a
way in which I see myself, a way
I think about my craft, my
profession, and a way I justify
the work I put out to the world:
that it aligns with these
values. So it’s very
important to me what these
values are. And it’s
frustrating to see open source
defined in reaction to closed
source software, because
personally I don’t care
about closed source software
that much.
I never really cared much about
fighting Microsoft, and I
certainly don’t care now.
I see myself as a builder; this
is what always drew me towards
programming. The desire to build
new things. This is our
privilege as programmers, that
we always have the opportunity
to build new things. If
we’re asked to do
something again and again and
again, you always have the power
to do it in a more abstract way,
to generalize it away, until you
can start to ignore the requests
and move on to another problem.
This is something unique thing
to computer programming. These
are the kind of unique
attributes that make us
different as a profession and as
a craft than just about anything
I can think of.
So I’m frustrated. Here we
are stuck in this notion of a
license as a self-definition. I
want to find a new
self-definition, a new idea of
what makes us us.
What Makes Us Us
So… what makes us us?
I was saying about Django, the
community is not particularly
enthusiastic about philosophy.
Or maybe I should say,
Django’s philosophy is:
the value of the code is the
thing you do with it. These
abstract discussions about
architecture, reuse, big
plans… instead, Django as
a community encourages you to
keep your head in the code,
think about what you want to do,
and then do it. Don’t
shave yaks.
But I’m not here to tell
you to get philosophical about
freedom, or to berate you for a
functional definition of value.
I’d like to look at this
community for what it is, and
ask: what is the value system
here? Maybe it isn’t
described, but I also
don’t think it is
therefore absent.
So… when I say I identify
as an open source programmer,
what is it that I am identifying
as?
I don’t believe licensing
makes something truly open
source. There was this clamour
in the past to get companies to
open source their products. This
has stopped, because all the
software that got open source
sucked. It’s just not very
interesting to have a closed
source program get open sourced.
It doesn’t help anyone,
because the way closed source
software is created in a very
different way than open source
software. The result is a
software base that just does not
engage people in a way to make
it a valid piece of software for
further development. At least
not unless you have something
peculiar going on… an
economic force like you had
behind Mozilla that could push
things forward even in the midst
of all the problems that project
had. One might even ask, is
Mozilla still suffering from
that proprietary background,
when something like KHTML or
WebKit which came from a truly
open source background, and has
been a more successful basis for
collaboration and new work.
So whatever it is that makes
something open source,
it’s not just licensing.
Given a codebase, we can’t
necessarily expect that someone
going to care about it and love
it and make it successful. A lot
of people have described what
makes a successful open source
codebase; I’d like to talk
some about what the communities
look like.
Open source works as a fairly
loose federation of people
together. Everyone involved is
involved as an individual.
Companies seldom participate
directly in open source.
Companies might use open source,
they might sponsor people to
work on open source projects,
they might ask an employee to
act as a liason. But it’s
not cool to submit a bug as a
company. You submit it as
yourself. If someone asks a
question, you answer as
yourself. You don’t join a
mailing list under the
company’s name. And even
when you put a company name on a
product, it’s hard to
relate to the product as a
project without some
sense of authorship, of the
underlying individual.
There’s also very little
money being moved about.
There’s not a lot of
commercial contracts. You might
get software, you might get bug
fixes, you might get reputation,
but there’s seldom any
formal way setup to introduce
commerce into the community. How
many projects let you pay to
escalate a bug? Even if everyone
involved might like that,
it’s just not there.
But I want to get back to
individuals. How things are
created is not that someone
determines a set of priorities,
lays them out, then people work
on implementation based on those
priorities. That of course is
how things typically work at a
company, as an employee. But
open source software and open
source projects are created
because an individual looks at
the world and sees an
opportunity to create something
they think should exist. Maybe
it resolves a tension
they’ve felt in their
work, maybe it allows that
person to respond to the
priorities from above better,
but the decision to implement
lies primarily with the
implementor. When someone makes
a decision to move a product
from simply private code —
regardless of the license
— to being a real open
source project, that decision is
almost always driven by the
programmer.
Underneath most open source work
there is a passion for the craft
itself. This is what leads to a
certain kind of quality that is
not the norm in closed source
software. It’s not
necessarily less bugs or more
features, but a pride in the
expression itself. A sense of
aesthetic that applies to even
the individual lines of
software, not just to the
functionality produced. This
kind of aesthetic defies
scheduling and relies on
personal motivation.
As open source programmers we
are not first concerned with how
a task fits into institutions,
how a task can be directed by a
hierarchy or an authority, or
even how the task can be
directed by economics. The tasks
that we take on are motivated by
aesthetic, by personal
excitement and drive.
We are also in a profession
where there is little stasis. If
you can create something once,
you can create it a thousand
times, through iteration or
abstraction. You can constantly
make your own effort obsolete. A
good programmer is always trying
to work themselves out of a job.
Djangocon didn’t exist a
couple years ago. Django
didn’t exist only a few
years ago. And I don’t
think there’s anyone here
who thinks that, having found
Django, they’ve reached
some terminal point. It’s
hardly even a point to pause.
There’s a constant churn,
a constant push forward that
we’re all participating
in.
As a result it’s demanded
of us that we have a tight
feedback cycle, that education
is not a formal affair but a
constant process in our own
work. There’s a constant
churn, and a professional sense
we’re kind of like fruit
flies. A generation of knowledge
and practice is short enough
that the evolution is rapid and
visible. You don’t have to
be particularly old or even
thoughtful to see the changes.
You can look back even on your
own work and on communities to
see changes over the course of a
couple years, to see changes and
shifts and a maturing of the
work and the community.
Another attribute of open
source: our communities are ad
hoc and temporary. We do not
overvalue these communities and
institutions; we regularly
migrate, split, recombine, and
we constantly rewrite. There is
both an arrogance and a humility
to this. We are arrogant to
think This Time Will Be
Different. But we are humble
enough to know that last time
wasn’t different either.
There will always be a next
thing, another technique,
another vision.
Because of the ad hoc nature of
the communities, we don’t
have long collective plans. The
ad hoc community may be the
intersection of different
personal long range
plans, a time when different
visions somehow coincide in a
similar implementation. Or
perhaps it’s just
serendipity, or leadership. But
we make each decision anew. I
believe this protects us from
being misled by sunk costs. The
idea of a sunk cost is that when
you make an investment,
you’ve put in effort, that
effort is gone. Just because
you’ve put in effort
doesn’t mean you’ve
received value, or that the path
of investment remains valid. But
as humans we are highly
reluctant to let go of a plan
that we’ve invested in. We
have a hard time recognizing
sunk costs.
I believe in our developer
community we approach our work
with sufficient humility that we
can see our work as simply a
sunk cost. Our effort does not
entitle us to any particular
success, so we can choose new
directions with more rationality
than an institution. Though it
can also be argued that we are
too quick to dismiss past
investments; there is a
youthfulness even to our oldest
members.
We do not have hierachies with
decision makers above
implementors. Some people have
veto power (a BDFL), but no one
has executive power. A
decision only is valid paired
with an implementation. You
cannot decide something based on
information you
wish was true; you
cannot decide on something then
blame the implementors for
getting it wrong. We are in this
sense vertically integrated,
decision and implementation are
combined. The result may be
success or failure, commitment
or abandonment, but the
hierarchy is flat and the
feedback loop is very tight. And
if an individual feels stymied,
there is always another
community to join or create.
Though this is only a start,
it’s these attributes that
I would prefer define us, not
licenses.
I also would like that this
could be a model for how other
work should be done.
Why Us?
Why would we, as programmers, be
unique or worthy of emulation? I
mentioned before that we
constantly work ourselves out of
our job. We also create the
tools we use to do the work. We
define the structure of our
communities. We’re
consistently finding novel ways
to use the internet build those
communities. It’s not that
we as a group are somehow
uniquely wise, or some Greatest
Generation, but we have become
distinctly self-empowered. There
is a uniqueness to us. It might
be a coincidence of history, but
it is there.
A question I might then ask: is
there a political meaning to
this? This is the form our craft
takes, but does that mean
anything? We work with
computers, someone else might
work with their hands, an artist
considers color, a salesperson
learns how to put on a good
smile.
I haven’t quite figured
this out yet, but I think
there’s something in this.
Over the years I’ve found
myself looking at politics in a
increasingly technocratic lens;
more so than as a liberal,
conservative, or radical. That
is, instead of looking at the
world and seeing what’s
wrong about it, and explaining
it in terms of a class struggle,
a cultural conflict, in terms of
advocacy or invented enemies or
allies, I see a system that just
works how it works. It’s
more like gears than like a war.
The gears turn and sometimes we
don’t like what results,
but it’s not malice.
But I also don’t think we
are slaves to the technical
functioning of the system. None
of us are inevitably caught up
in some statistical outcome of
markets, or condemned by money
in politics or advertising. At
any time we can say Here Is What
I Believe, and it is as powerful
as any of those other things;
we’re too quick to look at
the people who aren’t
asserting a belief, who
aren’t asserting their own
potential for self-empowerment
and direction, and we ignore
everyone who is aware and
concerned and attempting
self-determination. We are at
danger of ignoring the great
potential around us.
It is in this sense that I
wonder not just how we can
spread the idea of freedom
through licensing, which has
inspired the free culture
movement, but also how we can
spread this idea and practice of
individual action, of combining
decision and implementation, and
of constant ad hoc
collaboration.
I’m not just thinking of
politics directly, but of
professional lives as well.
Right now we’re talking
about healthcare. It’s a
very political issue, and yet
healthcare is ultimately a
profession, a job, an action.
How we work on that,
collaboratively or not, is as
political as any aspect of the
system.
One anecdote that made me think
about this, is a task I had that
involved putting authentication
in front of a mailing list. The
mailing list happened to be for
wound, ostomy, and continence
nurses, and in the process of
the job I read a bunch of their
emails from the archives. As
wound nurses they spent a lot of
time asking about specific
questions — maybe a wound
that wouldn’t heal, they
kept draining the puss and it
discharge kept reappearing, and
did anyone have ideas of the
next technique to try?
Reading a few of these I could
tell this was a profession where
you needed a strong stomach. But
the whole interaction, the way
they described problems, the way
people came back with answers,
it felt very familiar to me. It
was the same kind of discussions
I could imagine having about
Linux administration or
debugging. And the goals were
similar. No one was making
money, there wasn’t really
reputation on the line, it was
just people who wanted to help
their patients and who wanted to
help each other.
So that mailing list was great,
but it’s unfortunately not
that common. And if nurses were
open to that kind of
collaboration, doctors
don’t seem nearly as
ready. And there’s a lot
of professions where
there’s not even that
thoughtfulness. I believe in any
profession there’s the
ability to do it well or not;
there’s nothing so rote or
well understood that
there’s no room for
improvement. It doesn’t
have to be fancy technology, it
can just be a technique, a way
of managing work; all things
worth doing have some way of
improving, by bringing in this
same sense of collaboration and
individual action and
thoughtfulness, all things can
be implemented better than they
are now. What I’m
describing isn’t a fancy
new website for professionals,
but about people look at their
own work differently; the
technology is not the hard part.
The Political
Changing how people look at
their work I think is political.
It involves individual
empowerment. It can mean
economic change. I also think it
deemphasizes competition. When I
think about Pylons, or Django,
or TurboGears, or WSGI,
there’s competition, but
it’s also collegial.
There’s not really that
much of a sense of survival. We
aren’t carving out
territories, we’re just
finding paths to some unknown
end. If something else wins out,
well, we’re all just along
for the ride. In the end it is
inevitable that something else
other than what any of
us are working on will win out
over what any of us are doing.
Just like everyone eventually
loses their job at least to
death or retirement.
There’s no permanency. But
if we can be individually more
productive, it doesn’t
have to mean we’ve put
someone else out. It
could mean we all, all
of society, all of humanity,
just do more. Why do we
have to set ourselves against
the Chinese, or Europe against
the U.S.? Why do we have to set
ourselves one economy against
another?
Or consider government itself:
we’re obsessed with our
elected officials, but of course
government is far larger than
just the elected officials. The
U.S. Federal Government alone
has 1.8 million employees. We
constantly threaten to institute
accountability, meaning that
we’ll poke and prod
government workers from the
outside and expect better
outcomes. That we expect
anything to come of this is
absurd, but somehow
accountability has become an
easy alternative to constructive
suggestions for improvement.
But why shouldn’t we
expect that government workers
want to do better? I
believe in fact those people
doing the work are especially
well equiped to figure out
how to do better. But
it’s not automatic. They
aren’t empowered in a
system that is so exceptionally
hierarchical. Lately we’ve
seen lots of efforts to ask the
public how to do government work
better, but we’ve seen
nothing asking
government how to do
government work better.
These are the kinds of things
I’d like to see us all
think about more: open source
has done incredible things, has
inspired new ideas, about more
than just software and
engineering, but I think we have
yet more things to give.
Thank you for your time.

Configure the type of expiration and the expiration action to use.
Set the region’s
statistics-enabled
attribute to true.The statistics used for expiration are available directly to the application through the
CacheStatistics
object returned by theRegion
andRegion.Entry
getStatistics
methods. TheCacheStatistics
object also provides a method for resetting the statistics counters.Set the expiration attributes by expiration type, with the max times and expiration actions. See the region attributes listings for
entry-time-to-live
,entry-idle-time
,region-time-to-live
, andregion-idle-time
in <region-attributes>.
For partitioned regions:
- On a partitioned region, expiration is supported only for the region’s entries, not for the region itself. Region-wide expiration attributes, such as
region-time-to-live
andregion-idle-time
do not apply to the data items in partitioned regions. - To ensure reliable read behavior when working with partitioned regions, use the
entry-time-to-live
attribute, not theentry-idle-time
attribute. - You cannot use
local-destroy
orlocal-invalidate
expiration actions in partitioned regions.
Replicated regions example:
// Setting standard expiration on an entry
<region-attributes statistics-enabled="true">
<entry-idle-time>
<expiration-attributes timeout="60" action="local-invalidate"/>
</entry-idle-time>
</region-attributes>
Override the region-wide settings for specific entries, if required by your application. To do this:
Program a custom expiration class that implements
org.apache.geode.cache.CustomExpiry
. Example:// Custom expiration class // Use the key for a region entry to set entry-specific expiration timeouts of // 10 seconds for even-numbered keys with a DESTROY action on the expired entries // Leave the default region setting for all odd-numbered keys. public class MyClass implements CustomExpiry, Declarable { private static final ExpirationAttributes CUSTOM_EXPIRY = new ExpirationAttributes(10, ExpirationAction.DESTROY); public ExpirationAttributes getExpiry(Entry entry) { int key = (Integer)entry.getKey(); return key % 2 == 0 ? CUSTOM_EXPIRY : null; } }
Define the class inside the expiration attributes settings for the region. Example:
<!-- Set default entry idle timeout expiration for the region --> <!-- Pass entries to custom expiry class for expiration overrides --> <region-attributes statistics-enabled="true"> <entry-idle-time> <expiration-attributes timeout="60"> <custom-expiry> <class-name>com.company.mypackage.MyClass</class-name> </custom-expiry> </expiration-attributes> </entry-idle-time> </region-attributes>
The gfsh equivalent of the above XML is:
gfsh> create region --name=region1 --type=REPLICATE --enable-statistics \ --entry-idle-time-expiration=60 --entry-idle-time-custom-expiry=com.company.mypackage.MyClass
When the primary expires entries, it requests last-accessed statistics from the secondaries. The primary adopts the most recent access time and reschedules the expiration, if warranted. This is done only for distributed expiration actions, and applies to both partitioned and replicated regions.
You can also configure regions using the gfsh command-line interface. See Region Commands.
Configuring the Number of Threads for Expiration
You can use the gemfire.EXPIRY_THREADS
system property to increase the number of threads that handle expiration. By default, one thread handles expiration, and it is possible for the thread to become overloaded when entries expire faster than the thread can expire them. If a single thread is handling too many expirations, it can result in an OOME. Set the gemfire.EXPIRY_THREADS system property to the desired number when starting the cache server.


About mutations
Every GraphQL schema has a root type for both queries and
mutations. The mutation
type
defines GraphQL operations that change data on the server. It is
analogous to performing HTTP verbs such as POST

Raises: ValidationError: The given object is not an acceptable representation of the given WSDL-defined complex type. |
Validates a string representing a simple type against its WSDL definition. Args: wsdl_types: dict WSDL-defined types in the same service as the given type. obj: str String representing the given simple type. xsi_type: str The simple type name defined in the WSDL. Raises: ValidationError: The given object is not an acceptable representation of the given WSDL-defined simple type. |
Validates a list representing an array type against its WSDL definition. Args: wsdl_types: dict WSDL-defined types in the same service as the given type. obj: list List representing the given array type. xsi_type: str The array type name defined in the WSDL. |
Validates any given object against its WSDL definition. This method considers None and the empty string to be a valid representation of any type. Args: wsdl_types: dict WSDL-defined types in the same service as the given type. obj: object Object to be validated. Depending on the WSDL-defined type this is representing, the data type will vary. It should always be either a dictionary, list, or string no matter what WSDL-defined type it is. xsi_type: str The type name defined in the WSDL. Raises: ValidationError: The given WSDL-defined type has no definition in the WSDL types map. |

JS ariato.js
Ariato comes with a tiny JavaScript skeleton which runs its components. It is ultra lightweight since there are less than 100 lines of JavaScript with no dependencies. Of course you can use it for your own application if you want to avoid other heavy JavaScript frameworks. It works with simple plain old JavaScript and standard HTML.
There are only 3 things to know that will be detailed below : controllers, events and roles.
A controller is a JavaScript function connected to a DOM element. Ariato looks for all the data-ariato="ControllerName"
attributes and instanciates the relevant controller.
It handles nested names such as data-ariato="Account.Form"
. In that case a new object Account.Form
is created and receives the DOM element as an argument.
The controller is automatically initialized with events and roles that we will discuss in the next sections. Moreover you can access directly to the container element with this.node
from the controller.
Ariato helps you to listen to DOM events via the data-event
attribute. It must contain the event name following by an arrow and the function name of the controller. The function is called with the event as the only argument. It's possible to specify as many event/function combinations you need.
Roles help you to access easily to DOM elements from your controller with a nice name instead of a CSS selector.
Roles are defined via the data-role="roleName"
attribute.
All roles are stored in arrays into this.roles.roleName
.
However if there is only 1 occurence of the role, there is the following shortcut to access it : this.roleName
.
In this example that is the case for saveButton but not for textFields.

Pepe in Porto fan appeal as Rangers showdown looms into view
The veteran centre-back has begged supporters to trust them as they prepare to travel to Glasgow.
by Mark WalkerPepe has asked Porto fans to trust them ahead of the trip to face Rangers on Thursday.
The veteran defender has pleaded with supporters to get behind the team and manager during the Europa League showdown at Ibrox .
Porto have recently been rocked after a series of poor performances, which included Rangers holding the Portuguese giants to a 1-1 draw.
Manager Sergio Conceicao admitted there was an environment of distrust surrounding the club after the fans whistled at them despite beating Aves 1-0 at home.
And Pepe, 36, has demanded the fans are more patient before they play Rangers in Glasgow.
He said: "The fans must realise we cannot win every match by three or four goals. It's the same three points no matter the scoreline. Football doesn't work that way.
"It's not an easy league and every game is difficult. To get the win was very important.
"I say to the fans that we have to be united - the players and the supporters. We need them to trust us.
"There is a great team spirit at this club and we now go to Scotland with plenty of confidence determined to get a win this time against Rangers."

ESPN’s Prediction For Texans-Colts Tonight
by Matt HladikNow is the time of the season when things get serious in the NFL. Teams begin to make their push for division titles and playoff spots.
Tonight’s Thursday Night Football matchup between the Indianapolis Colts and Houston Texans will have a major impact on the AFC South. Right now, both teams are tied for the division lead with identical 6-4 records.
The Tennessee Titans are right behind at 5-5, and while the Jacksonville Jaguars don’t have much room for error at 4-6, they are still in the hunt.
ESPN has released its final prediction for tonight’s game. Not surprisingly, the Texans are favored at home.
According to the Football Power Index (FPI), Houston has a 65.4 percent chance of winning. Indianapolis is at 34.3 percent, with a 0.3 percent shot the game ends in a tie.
These two teams met last month in Indianapolis, with the Colts earning a 30-23 victory. Jacoby Brissett was the star, throwing for 326 yards and four touchdowns, two of them to Zach Pascal. The Colts also intercepted Deshaun Watson twice in that game.
Tonight’s game will kick off at 8:20 p.m. ET. You can catch the action on FOX and NFL Network.

Privacy at risk
November 2, 2014
It has been widely believed that no matter what technology is simply good. It absolutely make us very much convenient and comfortable. It has provided enormous benefits to the world. The prehistoric discovery of how to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale.
Gorilla using branch to check the depth of river.It is tech.
However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons. Furthermore, internet has given a lot of benefits to human society, but also it is not always completely safe, either. When you read Google’s privacy policy carefully, it is clear that they retain the right to make significant decisions about our data without regard for our interests. With the new movement to store everything on the cloud, who knows if a single hacker would be able to take down entire chunks of the internet. As our economy becomes more dependent on bits than atoms, how will we protect these resources from being damaged or devalued by hackers? In conclusion, modern technologies can very well be a double-edged sword, from safety to connectedness. They do have their advantages, but as with many revolutionary inventions, they can radically change our lives, for better or worse.So, as much as we do our best to make profits and better,we also have to do our best to protect our privacy and so on. Make future IT student have resposibility through education and Goverments and IT industry must do their best to protect privacy.

PSALMS 98
A psalm.
1 Sing to Yahweh a new song
because he has done wonderful things!
By his power he has defeated his enemies.
2 Yahweh has declared to people that he has defeated his enemies;
he has revealed that he has punished his enemies,
and people in all the world have seen that he has done it.
3 As he promised to us Israelite people,
he has faithfully loved us and been loyal to us.
People who live in very remote places in all the earth
have seen that our God has defeated his enemies.
4 All you people everywhere should sing joyfully to Yahweh;
praise him while you sing and shout joyfully!
5 Praise Yahweh while you play the lyres,
playing delightful music.
6 Some of you should blow trumpets and other horns
while others shout joyfully to Yahweh, our king.
7 The oceans and all the creatures that are in the oceans should roar to praise Yahweh.
Everyone on the earth should sing!
8 It should seem as though the rivers were clapping their hands to praise Yahweh
and that the hills were singing together joyfully in front of Yahweh
9 because he will come to judge everyone on the earth!
He will judge all the people groups in the world justly and fairly.

# Password phonetics #### Disable text-to-speech function The Access Manager web interface provides a text-to-speech function that will read out the value of the password in the NATO phonetic alphabet, where supported by the user’s browser.
Selecting this option will hide the text-to-speech function in the web app.
#### Hide phonetic breakdown The Access Manager web interface provides breakdown of the password in the NATO phonetic alphabet. This makes it easier to read passwords out loud to another person.
Selecting this option will hide the phonetic password breakdown in the web app.
#### Prefix upper-case letters with Provide a value such as upper-case or capital to prefix letters with in the phonetic breakdown.
#### Prefix lower-case letters with Provide a value such as lower-case to prefix letters with in the phonetic breakdown. We suggest prefixing only upper-case letters.
#### Group size Specify how many characters should be in each group in the phonetic breakdown. This changes how many characters are displayed on each line in the phonetic breakdown.

$template{name="sample-readme-html-header" title="Search Engine demo"}$
What does the sample do?
This sample application performs as a web search engine. It takes a search query and performs the search starting from a specified URL.
The application will follow every link of each visited page, up to the specified link depth limit.
It will then return the list of URLs matching the search query, ordered by relevance.
The visiting of the pages is realized through the integration of JPPF with the Smart and Simple Web Crawler project.
The search and page indexing are implemented thanks to the Lucene project from the Apache Foundation.
How do I run it?
Before running this sample application, you must have a JPPF server and at least one node running.
For information on how to set up a node and server, please refer to the JPPF documentation.
Once you have a server and node, from a command prompt, type: "ant run"
How do I use it?
The GUI is separated in two main parts, the search parameters at the top and the search results at the bottom.
The "Compute" button submits the web search for processing by JPPF.
The "Reset defaults" button restores the start url, search query and link depth to their original values
The web search relies on 3 parameters:
- start URL: this is the URL of the web page from which links will be followed recursively. To limit the scope (and length) of the search,
a filter is set so only links to the same server will be followed
- search query: this is what to search on the visited pages; interpreted as Lucene query syntax
- search depth: this parameter also limits the scope of the search, by restricting the depth of the chains of links that can be followed.
For example: if the depth is set to 1, only the links found on the start page will be followed. If it is set to 2, the links found in the
pages specified by the links in the start page will also be followed
When the search is over, the results are displayed in the search results panel, in descending order of relevance.
What integration features of JPPF are demonstrated?
- Integration with other Java-based open source projects.
Among other things, you will notice that the 3rd-party libraries (including Lucene and Smart and Simple Web Crawler) remain in the
classpath of the client application.
- Using JPPF as part of a workflow.
In this sample the search is realized through multiple invocations of JPPF:
- once for every search depth level to perform the link navigation and gather links for the next level
- once for the actual indexing and searching of the pages, once all links have been gathered
This design explains why the search can take a long time since, contrary to search engines such a Yahoo or Google, the indexes are
recomputed during the search.
- Integration with a graphical user interface.
How can I build the sample?
To compile the source code, from a command prompt, type: "ant compile"
To generate the Javadoc, from a command prompt, type: "ant javadoc"
I have additional questions and comments, where can I go?
If you need more insight into the code of this demo, you can consult the source, or have a look at the
API documentation.

Joy has a very gentle character. She is ready to shelter any trainer and help any Pokemon at any time of the day or night. Although Joy from Grinji scolded Ash and his friends for waking her. But all in all, Joy is very kind. They can also conduct inspections (in detail in the series "The Mystery of the Dark City").
