Over the perior of 28 years, we have seen increase in number of students applying for college. We used the enthicity breakdown for bachelor degree enrollment in US, and found a significant increase in enrollment of minority groups such as hispanic, asians, and black enthic groups. Of all enthnic groups, American Indians and Alaskan Natives have not grown much compared to other ethnic groups.
In terms of education inequality, we used the education gini coeffecient value. Gini coeffecient is a normalized value with the cumulative percentage of the income on the vertical axis, and the cumulative percentage of the population on the horizontal axis. World bank document of the detail gini coeffecient calculation can be found in the link. The line at 45 degrees represents perfect equality of education. The Gini coefficient can then be thought of as the ratio of the area that lies between the line of equality and the Lorenz curve (marked A in the diagram) over the total area under the line of equality (marked A and B in the diagram); if area A is small with 0 gini coeffecient, it represent perfect equality of education. If area of A is large and have gini coeffecient of 1, it represent perfect inequality.
When we observing the same value for female population to the total population education gini coeffecient, the gap between the equilibrium line and the scatter plot is wider than that of total population. This observation tells that there are wider inequality in number of schooling in the demographics of female than that of total populaton.
Compared to female population, the male population showed less spread between the equilibrium line to the scatter plot for most age range, however for the population above 25 years of age showed more wider spread than that of female's. We can assume that there maybe more population achieving higher education than the female population resulting in wider gender gap.
In summary, from the data we gathered, there were education inequality in the ethnicity and the gender we observed. Minority group still has lower population of applying for college, and overall population still have less years of education completion for female than that of male population.


Chennai Public School is a Central Board of Secondary Education school located in Anna Nagar, Chennai, India.It also has another branch in Thirumazhisai, Chennai, Tamil Nadu, India. The pre-primary and early years learning programme at CPS is a system where the tenets of Montessori education are scientifically combined with tried and tested teaching methods, focussing on language development and logical thinking, for children to start their first steps into the education system.
To kindle a conducive learning environment on par with the best institutions worldwide, Chennai Public School has spared no effort or investment to ensure that the best infrastructure is made available to students to enable them to pursue their education with ease and comfort.
Chennai Public School was one of the first schools in India to have smart boards in all the classrooms and also a 5.1 theatre system in all classrooms.
Chennai Public School has etched a covetous place as one among the top 50 Schools in India, Shaping Success in the 2017 ranking conducted by the Future 50 - Fortune Magazine. Over 250 schools from 60+ cities all over the country participated in this ranking.
ATAL tinkering labs take CPS one step closer to the vision ‘Cultivate one Million children in India as Neoteric Innovators’.They are the pivots of innovation that foster imagination and creativity in young minds.
Students are segregated into four houses namely Alphard House, Canopus House, Diadem House and Plasma House. Intra-mural games and sports are conducted to promote healthy competitions among the four houses where the adrenaline is gushed up as they take part in all events energetically.
Chennai Public School was one of the first schools in India to have smart boards in all the classrooms and also a 5.1 theatre system in all classrooms.
One of the major parts of learning is the experience gained by spending time with peers going through the same courses. Many people like discussing and learning through group studies.This lack of human Interaction is very prominent in these classes.

There are some times when I want to party quite more than other times, that was my case on that friday, I was quite happy for how the week went on my job, that night two great DJs were playing on a great party, all my close friends and my girlfriend were with me, it was a 3-day weekend (because of a holyday on monday), I just couldn't ask for more. But human nature is like that, I did want more. Although I've been taking pills for over 4 years I have never tried LSD, maybe because is not so easy to find, or because none of my friends take it on a regular basis, but that night some dealer came with new 'little papers' (that's how we call LSD here), he said they were great, so I finally decided to take one.
A girl friend (not my girlfriend) got it for me, I took it whole, not just a piece, she opened her eyes and mouth wide as she saw me and told me not to take that much, that half is enough, but I still took it whole. I kept it on my tounge as was told, but my friends kept telling me I had taken too much, so after 30 minutes I gave half to my girlfriend, she hadn't take it before too.
I took also half a pill of MDA, two hours later took another half. We call that combination here in Medellin, Colombia (LSD & pills) a 'wedding'.
At that time the party was starting, about 45 minutes later I started to feel very different, it was strange but great, the first change I noticed was that music seemed to flow in 3-D, the speakers at that place where just at the front, but I heard the music coming from everywhere, the bass from one side, some keyboards from other, cymbals from behind, all flowing through me, it was quite a sensation.
As time went by I started to look things differently too, people left traces as they walked, but what was quite unique were the way that girls looked, in that party there were quite a lot of cuties, very hot chicks, I could feel like their legs or arms or their butt where like a source of energy, it was great, I felt quite aroused.
The first 6 hours I didn't felt as dancing too much, I was quite overwhelmed by this new sensations, I felt like laughing a lot, sometimes I even shed a couple of tears of joy. When the party finished we went back to the city to a friend's apartment, I didn't drive, I gave the keys of the car to a friend, it was 8:00 AM.
This time I felt more much eager to dance, a friend bought some white wine, more pills, and we started the party again. About 12 hours after I took the LSD I sat and closed my eyes, after a while the music started to flow with colors, it was a great spectacle, since every kind of sound had its own colour and flowed the way it sounded, I lasted 30 minutes like that (my friends told me). It was quite a day and night of partying again, I just couldn't sleep, neither I could stay still easily, I lasted until the other day at 3:00 PM partying there.
At that moment I felt quite exhausted, like I would weigh 1 ton, I just went directly to sleep, felt awful, but not very bad.
It was a really unique experience, my friends tell me that the next time I should be in a place with more lights and colours, and even on a field, LSD is quite a strong drug, I believe it's not for the weak of mind.

Ping Pong States Example
This example implements a statechart where two states communicate by posting events to the state machine. The state chart looks as follows:
The pinger
and ponger
states are parallel states, i.e. they are entered simultaneously and will take transitions independently of eachother.
The pinger
state will post the first ping
event upon entry; the ponger
state will respond by posting a pong
event; this will cause the pinger
state to post a new ping
event; and so on.
class PingEvent : public QEvent { public: PingEvent() : QEvent(QEvent::Type(QEvent::User+2)) {} }; class PongEvent : public QEvent { public: PongEvent() : QEvent(QEvent::Type(QEvent::User+3)) {} };
Two custom events are defined, PingEvent
and PongEvent
.
class Pinger : public QState { public: Pinger(QState *parent) : QState(parent) {} protected: void onEntry(QEvent *) override { machine()->postEvent(new PingEvent()); fprintf(stdout, "ping?\n"); } };
The Pinger
class defines a state that posts a PingEvent
to the state machine when the state is entered.
class PingTransition : public QAbstractTransition { public: PingTransition() {} protected: bool eventTest(QEvent *e) override { return (e->type() == QEvent::User+2); } void onTransition(QEvent *) override { machine()->postDelayedEvent(new PongEvent(), 500); fprintf(stdout, "pong!\n"); } };
The PingTransition
class defines a transition that is triggered by events of type PingEvent
, and that posts a PongEvent
(with a delay of 500 milliseconds) to the state machine when the transition is triggered.
class PongTransition : public QAbstractTransition { public: PongTransition() {} protected: bool eventTest(QEvent *e) override { return (e->type() == QEvent::User+3); } void onTransition(QEvent *) override { machine()->postDelayedEvent(new PingEvent(), 500); fprintf(stdout, "ping?\n"); } };
The PongTransition
class defines a transition that is triggered by events of type PongEvent
, and that posts a PingEvent
(with a delay of 500 milliseconds) to the state machine when the transition is triggered.
int main(int argc, char **argv) { QCoreApplication app(argc, argv); QStateMachine machine; QState *group = new QState(QState::ParallelStates); group->setObjectName("group");
The main() function begins by creating a state machine and a parallel state group.
Pinger *pinger = new Pinger(group); pinger->setObjectName("pinger"); pinger->addTransition(new PongTransition()); QState *ponger = new QState(group); ponger->setObjectName("ponger"); ponger->addTransition(new PingTransition());
Next, the pinger
and ponger
states are created, with the parallel state group as their parent state. Note that the transitions are targetless. When such a transition is triggered, the source state won't be exited and re-entered; only the transition's onTransition() function will be called, and the state machine's configuration will remain the same, which is precisely what we want in this case.
machine.addState(group); machine.setInitialState(group); machine.start(); return app.exec(); }
Finally, the group is added to the state machine, the machine is started, and the application event loop is entered.

Hi! My name is Jack Ahern (he/him). I am from Philadelphia, PA,
and love to ski. Boulder has been an amazing place for me
to continue my education and explore the amazing mountains
of the west. I am new to web development, but am super excited to
begin my journey.
I am interested in UX/UI job positions, so I want to have web
development knowledge to complinment my work as a designer.
At the same time, you never really know where your future may lead,
and web-development could end up being a career for me. I love
the idea of designing websites and hope we do some cool projects
this semester. I know that coding is all about practice, so my goal
is to code a little bit each day during the week. I have friends who
are into coding for fun nowadays, and would love to share that passion.
Web development is by far the most enticing area of coding to me.

1. Printing on the Terminal
In this chapter, you will learn:
- How to write and run your first program in the Rust Language
- How to output texts and numbers on the terminal
- How to write a small script that makes more readable the output of the compiler // What is its mean?
- How to write comments in your code
clear
rustc $* --color always 2>&1 | more
This script first clears the screen, then runs the rustc compiler with all the arguments you give to it. If the compilation is successful, or if it generates less than a screenful of error messages, it behaves like a normal run of rustc.

In this chapter, you will learn: - How to compute an arithmetic operation between integer numbers or between floating-point numbers - How to write a program containing several statements - How to print strings in several lines
fn main() {
println!("{}", "This \
is \
just one line");
}
This will print: This is just one line
fn main() {
println!("{}", "These
are
three lines");
}
or this:
fn main() {
println!("{}", "These\n\
are\n\
three lines");
}
Both will print: These are three lines
3. Naming Objects
In this chapter, you will learn: - The concepts of “value”, “object”, and “variable” - The concept of “mutability” of variables - The difference between initialization and re-assignment - How to avoid warnings for unused variables - The concept of “Boolean expression” - Which type checks are performed by the compiler for assignments - How some operators can perform both an arithmetic operation and an assignment - How to invoke functions defined in the Rust standard library
let _ = 12;
print!("{}", _)
let truth = 5 > 2;
let falsity = -12.3 >= 10.;
print!("{} {} {}", truth, falsity, -50 < 6);
//This will print true false true.
• ==: is equal to • !=: is different from • <: is less than • <=: is less than or equal to • >: is greater than • >=: is greater than or equal to
print!("{} {} {}", "abc" < "abcd", "ab" < "ac", "A" < "a");
//This will print true true true.
let truth = true;
let falsity = false;
println!("{} {}", ! truth, ! falsity);
println!("{} {} {} {}", falsity && falsity, falsity && truth,
truth && falsity, truth && truth);
println!("{} {} {} {}", falsity || falsity, falsity || truth,
truth || falsity, truth || truth);
//This will print: false true false false false true false true true true
print!("{} {}", true || true && ! true,
(true || true) && ! true);
This will print: “true false”.
4. Controlling Execution Flow
In this chapter, you will learn: • How to use if statements to execute different statements based on a Boolean condition • How to use if expressions to generate different values based on a Boolean condition • How to use while statements to repeat some statements as long as a Boolean condition holds • How to use for statements to repeat some statements for a definite number of times • What is the scope of validity of variables
5.Using Data Sequences
In this chapter, you will learn:
• How to define sequences of objects of the same type, having fixed-length (arrays) or variable-length (vectors)
• How to specify the initial contents of arrays or vectors, by listing the items, or by specifying one item and its repeat count
• How to read or write the value of single items of arrays or vectors
• How to add items to a vector or to remove items from a vector
• How to create arrays with several dimensions
• How to create empty arrays or vectors
• How to print or copy whole arrays or vectors
Multidimensional Arrays
let mut x = [[[[23; 4]; 6]; 8]; 15];
x[14][7][5][3] = 56;
print!("{}, {}", x[0][0][0][0], x[14][7][5][3]);
//This will print: "23, 56."
let x = [[[[0; 4]; 6]; 8]; 15];
print!("{}, {}, {}, {}.",
x.len(), x[0].len(), x[0][0].len(), x[0][0][0].len());
//This will print: "15, 8, 6, 4."
Vectors
To create sequences of objects whose size is defined at runtime, the Rust standard library provides the Vec type, shorthand for vector.
let x = vec!["This", "is"];
print!("{} {}. Length: {}.", x[0], x[1], x.len());
//This will print: "This is. Length: 2."
6. Using Primitive Types
In this chapter, you will learn:
• How to write numeric literals in hexadecimal, octal, or binary notation
• How to use the underscore character to make numeric literals easier to read
• How to use the exponential notation to write huge or tiny numbers in a compact form
• Which are the ten primitive integer numeric types, and the two primitive floating-point numeric types; which are their ranges; and when it is better to use each of them
• How to specify numeric literals of concrete types or of unconstrained types
• How to convert a numeric value to another numeric type
• The other primitive types: Booleans, characters, and empty tuples
• How type inference works
• How to express the types of arrays and vectors
• How to assign a name to a compile-time constant

let a: i16 = 12;
let b: u32 = 4;
let c: f32 = 3.7;
print!("{}", a as i8 + b as i8 + c as i8);
//This will print: "19".
let a = 500 as i8; //..............**..**..??......**..**..??......**..**..??......**..**..??......**..**..??......**..**..??...
let b = 100_000 as u16;
let c = 10_000_000_000 as u32;
print!("{} {} {}", a, b, c);
//Perhaps surprisingly, it will print: "-12 34464<PHONE_NUMBER>".
let _: i8 = 127; let _: i16 = 32_767; let _: i32 = 2_147_483_647; let _: i64 = 9_223_372_036_854_775_807; let _: isize = 100; // The maximum value depends on the target architecture let _: u8 = 255; let _: u16 = 65_535; let _: u32 = 4_294_967_295; let _: u64 = 18_446_744_073_709_551_615; let _: usize = 100; // The maximum value depends on the target architecture let _: f32 = 1e38; let _: f64 = 1e308;
let a: () = ();
let b = { 12; 87; 283 };
let c = { 12; 87; 283; };
let d = {};
let e = if false { };
let f = while false { };
print!("{:?} {:?} {:?} {:?} {:?} {:?}",
a, b, c, d, e, f);
//This code will print: "() 283 () () () ()".
7. Enumerating Cases
In this chapter, you will learn:
• How enums help in defining variables that can take on values only from a finite set of cases
• How enums can be used to implement discriminated union types
• How to use the match pattern-matching construct to handle enums
• How to use the match construct to handle other data types, like integer numbers, strings, and single characters
• How to use Boolean guards to generalize the pattern-matching of the match construct
enum CardinalPoint { North, South, West, East };
let direction = CardinalPoint::South;
match direction {
CardinalPoint::North => print!("NORTH"),
CardinalPoint::South => print!("SOUTH"),
_ => {},
}
error:
enum CardinalPoint { North, South, West, East };
let direction = CardinalPoint::South;
match direction {
CardinalPoint::North => print!("NORTH"),
_ => {},
CardinalPoint::South => print!("SOUTH"),
}
enum Result {
Success(f64),
Failure(u16, char),
Uncertainty,
}
let outcome = Result::Success(23.67);
match outcome {
Result::Success(_) => print!("OK"),
Result::Failure(error_code, module) =>
print!("Error n. {} in module {}",
error_code, module),
Result::Uncertainty => {},
}
//This will print: "OK".
enum CardinalPoint { North, South, West, East };
let direction = CardinalPoint::South;
print!("{}", match direction {
CardinalPoint::North => 'N',
CardinalPoint::South => 'S',
_ => '*',
});
//This will print: "S."
for n in -2..5 {
println!("{} is {}.", n, match n {
0 => "zero",
1 => "one",
_ if n < 0 => "negative",
_ => "plural",
});
}
This program will print: -2 is negative. -1 is negative. 0 is zero. 1 is one. 2 is plural. 3 is plural. 4 is plural.

8. Using Heterogeneous Data Structures
In this chapter you will learn how to define and use other composite types: • Tuples • Structs • Tuple-Structs They are useful to group objects of different types. At the end of the chapter, you’ll see some code style conventions.
const MAXIMUM_POWER: u16 = 600;
enum VehicleKind {
Motorcycle,
Car,
Truck,
}
struct VehicleData {
kind: VehicleKind,
registration_year: u16,
registration_month: u8,
power: u16,
}
let vehicle = VehicleData {

if vehicle.power > MAXIMUM_POWER {
println!("Too powerful");
}
9 Defining Functions
In this chapter you will learn: • How to define your own procedures (better known as “functions”) and how to invoke them • When and how you can have several functions with the same name • How to pass arguments to a function, by-value or by-reference • How to return simple and composite values from a function • How to exit prematurely from a function • How references to objects can be manipulated
fn f1() { print!("1"); }

f1();
fn f2() { print!("2"); }
f2(); f1(); f2();
}
// This will print: "1212".
fn f() { print!("1"); } //it is not used.
fn main() {
f(); // Prints 2
{
f(); // Prints 3
fn f() { print!("3"); }
}
f(); // Prints 2
fn f() { print!("2"); }
}
//This will print 232.
fn double(x: f64) -> f64 { x * 2. }
print!("{}", double(17.3));
//This will print "34.6".
10. Defining Generic Functions and Structs
// Library code
fn f<T>(ch: char, num1: T, num2: T) -> T {
if ch == 'a' { num1 }
else { num2 }
}
// Application code
let a: i16 = f::<i16>('a', 37, 41);
let b: f64 = f::<f64>('b', 37.2, 41.1);
print!("{} {}", a, b);
//This will print 37 41.1.
// Library code
fn f<T>(ch: char, num1: T, num2: T) -> T {
if ch == 'a' { num1 }
else { num2 }
}
// Application code
let a: i16 = f('a', 37, 41);
let b: f64 = f('b', 37.2, 41.1);
print!("{} {}", a, b);

12. Data Implementation
In this chapter, you will learn: • How to know how many bytes of stack are taken by objects of various types • How to shorten the path to access functions declared in external modules • How bits are stored in primitive type objects • How to know where an object is stored in memory • Why padding can increase the size taken by some objects • How vectors are implemented
use std::mem::*;
print!("{} {} {} {} {} {} {} {} {} {} {} {}",
size_of::<i8>(),
size_of::<u8>(),
size_of::<i16>(),
size_of::<u16>(),
size_of::<i32>(),

size_of::<i64>(),
size_of::<u64>(),
size_of::<f32>(),
size_of::<f64>(),
size_of::<bool>(),
size_of::<char>());
In any computer, this will print 1 1 2 2 4 4 8 8 4 8 1 4.
let mut v = vec![0; 0];
println!("{} {}", v.len(), v.capacity());
v.push(11);
println!("{} {}", v.len(), v.capacity());
v.push(22);
println!("{} {}", v.len(), v.capacity());
v.push(33);
println!("{} {}", v.len(), v.capacity());
v.push(44);
println!("{} {}", v.len(), v.capacity());
v.push(55);
println!("{} {}", v.len(), v.capacity());
This will print: 0 0 1 4 2 4 3 4 4 4 5 8
let mut v = vec![0; 0];
let mut prev_capacity = std::usize::MAX;
for i in 0..1_000 {
let cap = v.capacity();
if cap != prev_capacity {
println!("{} {} {}", i, v.len(), cap);
prev_capacity = cap;
}
v.push(1);
}
This (probably) will print: 0 0 0 1 1 4 5 5 8 9 9 16 17 17 32 33 33 64 65 65 128 129 129 256 257 257 512<PHONE_NUMBER>
13. Defining Closures
In this chapter, you will learn: • Why there is a need for anonymous inline functions, with type inference for the arguments and the return value type, without having to write braces, and which can access the variables that are alive at the function definition point • How such lightweight functions, named “closures”, can be declared and invoked
let factor = 2;
let multiply = |a| a * factor;
print!("{}", multiply(13));
let multiply_ref: &(Fn(i32) -> i32) = &multiply;
print!(
" {} {} {} {} {}",
(*multiply_ref)(13),
multiply_ref(13),
(|a| a * factor)(13),
(|a: i32| a * factor)(13),
|a| -> i32 { a * factor }(13));
// This will print: "26 26 26 26 26 26".
print!(
"{}",
(|v: &Vec<i32>| {
let mut sum = 0;
for i in 0..v.len() {
sum += v[i];
}
sum
})(&vec![11, 22, 34]));
//This will print "67" which is the sum of the numbers contained in the vector.
14. Using Changeable Strings
In this chapter, you will learn: • How static strings are implemented • How dynamic strings are implemented • How you can add characters to or remove characters from a dynamic string • How to convert a static string to a dynamic string, and conversely • How to concatenate strings
fn main(){
let mut a = "Hel";
print!("{}", a);
a = "lo";
print!("{}\n", a);
//This will print "Hello".
use std::mem::*;
let a: &str = "";
let b: &str = "0123456789";
let c: &str = "abcdè";
print!("{} {} {}",
size_of_val(a),
size_of_val(b),
size_of_val(c));
//This program will print 0 10 6.
// use std::mem::*;
let a: &str = "";
let b: &str = "0123456789";
let c: &str = "abcdè";
print!("{} {} {}; ",
size_of_val(&a),
size_of_val(&b),
size_of_val(&c));
print!("{} {} {}\n",
size_of_val(&&a),
size_of_val(&&b),
size_of_val(&&c));
//This program in a 64-bit system will print "16 16 16; 8 8 8", while in a 32-bit system it will print "8 8 8; 4 4 4".
let mut a: String = "He".to_string();
a.push('l');
a.push('l');
a.push('o');
print!("{}\n", a);
//This will print "Hello".
let mut a: String = "Xy".to_string(); // "Xy"
a.remove(0); // "y"
a.insert(0, 'H'); // "Hy"
a.pop(); // "H"
a.push('i'); // "Hi"
print!("{}\n", a);
//This prints "Hi".
let mut s1 = "".to_string();
s1.push('e');
let mut s2 = "".to_string();
s2.push('è');
let mut s3 = "".to_string();
s3.push('€');
print!("{} {}; ", s1.capacity(), s1.len());
print!("{} {}; ", s2.capacity(), s2.len());
print!("{} {}\n", s3.capacity(), s3.len());
//This may print: "4 1; 2 2; 3 3".
let mut s = "".to_string();
for _ in 0..10 {
println!("{:?} {} {}",
s.as_ptr(), s.capacity(), s.len());
s.push('a');
}
println!("{:?} {} {}: {}\n",
s.as_ptr(), s.capacity(), s.len(), s);
}
This, in a 64-bit system, may print:
0x1 0 0 0x7fbf95e20020 4 1 0x7fbf95e20020 4 2 0x7fbf95e20020 4 3 0x7fbf95e20020 4 4 0x7fbf95e20020 8 5 0x7fbf95e20020 8 6 0x7fbf95e20020 8 7 0x7fbf95e20020 8 8 0x7fbf95e2a000 16 9 0x7fbf95e2a000 16 10: aaaaaaaaaa

OGDI Vectors
Driver short name
OGDI
Build dependencies
OGDI library
OGDI vector support is optional in OGR, and is normally only configured if OGDI is installed on the build system. If available OGDI vectors are supported for read access for the following family types:
Point
Line
Area
Text (Currently returned as points with the text in the "text" attribute)
OGDI can (among other formats) read VPF products, such as DCW and VMAP.
If an OGDI gltp url is opened directly the OGDI 3.1 capabilities for the
driver/server are queried to get a list of layers. One OGR layer is
created for each OGDI family available for each layer in the datastore.
For drivers such as VRF this can result in a lot of layers. Each of the
layers has an OGR name based on the OGDI name plus an underscore and the
family name. For instance a layer might be called
watrcrsl@hydro(*)_line if coming out of the VRF driver.
(layer names can be simplified with OGR_OGDI_LAUNDER_LAYER_NAMES=YES
)
Alternatively to accessing all the layers in a datastore, it is possible to open a particular layer using a customized filename consisting of the regular GLTP URL to which you append the layer name and family type (separated by colons). This mechanism must be used to access layers of pre OGDI 3.1 drivers as before OGDI 3.1 there was no regular way to discover available layers in OGDI.
gltp:[//<hostname>]/<driver_name>/<dataset_name>:<layer_name>:<family>
Where <layer_name> is the OGDI Layer name, and <family> is one of: "line", "area", "point", or "text".
OGDI coordinate system information is supported for most coordinate systems. A warning will be produced when a layer is opened if the coordinate system cannot be translated.
There is no update or creation support in the OGDI driver.
Driver capabilities
Supports Georeferencing
This driver supports georeferencing
Error handling
Starting with GDAL 2.2 and OGDI > 3.2.0beta2, if the OGDI_STOP_ON_ERROR environment variable is set to NO, some errors can be gracefully recovered by OGDI (in VPF driver). They will still be caught by GDAL and emitted as regular GDAL errors.
Note: be aware that this is a work in progress. Not all recoverable errors can be recovered, and some errors might be recovered silently.
Configuration options
The following configuration options are available:
OGR_OGDI_LAUNDER_LAYER_NAMES=[YES/NO]: Defaults to
NO
. IfYES
, simplify layer names. For example : watrcrsl_hydro instead of 'watrcrsl@hydro(*)_line'
Examples
ogrinfo gltp:/vrf/usr4/mpp1/v0eur/vmaplv0/eurnasia 'watrcrsl@hydro(*)_line'
In the dataset name 'gltp:/vrf/usr4/mpp1/v0eur/vmaplv0/eurnasia' the gltp:/vrf part is not really in the filesystem, but has to be added. The VPF data was at /usr4/mpp1/v0eur/. The 'eurnasia' directory should be at the same level as the dht. and lat. files. The 'hydro' reference is a subdirectory of 'eurnasia/' where watrcrsl.* is found.
ogr2ogr watrcrsl.shp gltp:/vrf/usr4/mpp1/v0eur/vmaplv0/eurnasia 'watrcrsl@hydro(*)_line'
ogr2ogr polbnda.shp gltp:/vrf/usr4/mpp1/v0eur/vmaplv0/eurnasia 'polbnda@bnd(*)_area'
An OGR SQL query against a VMAP dataset. Again, note the careful quoting of the layer name.
ogrinfo -ro gltp:/vrf/usr4/mpp1/v0noa/vmaplv0/noamer \
-sql 'select * from "polbndl@bnd(*)_line" where use=26'

The first step with any new technology is getting it to run. The goal of this chapter is to get you started with a simple Yesod application, and cover some of the basic concepts and terminology.
Let’s get this book started properly: a simple web page that says Hello World:
{-# LANGUAGE TypeFamilies, QuasiQuotes, MultiParamTypeClasses,
TemplateHaskell, OverloadedStrings #-}
import
Yesod
data
HelloWorld
=
HelloWorld
mkYesod
"HelloWorld"

=
defaultLayout
[
whamlet
|
Hello
World
!|
]
main
::
IO
()
main
=
warpDebug
3000
HelloWorld
If you save that code in helloworld.hs
and run it with
runhaskell helloworld.hs
, you’ll get a web server
running on port 3000. If you point your browser to http://localhost:3000, you’ll get the following HTML:
<!DOCTYPE html> <title></title>Hello World!
We’ll refer back to this example through the rest of the chapter.


A Random Walk Down Wall Street
Firm foundation
Castle in the air
Academics have earned reputations by attacking these theories
Cannot be relied on to yield extraordinary profits
Academic community went busy with creating their own stock market valuation theories
"New investment technology"
Very basic
Widely followed on Wall Street
Efficient-market hypothesis explains why random walk is possible
Stock market is incredible in adjusting to new information - no one can predict its exact future course
Your guess is as good as an ape, a stockbroker, or even Carl Icahn
Academics says the way to beat the market is not to exercise superior clairvoyance
but to assume greater risk, because risk alone determines the degree of returns.
"The possibility of suffering harm or loss"
One-year Treasury bills, yields 2 percent and hold them until they mature
Common stock in my local electric utility for one year, anticipating a 5 percent dividend.
Investment risk: The chance that expected security returns will not materialize, and in particular, will fall in price.
Financial risk has generally been defined as the variance or standard deviation of returns
A security, whose returns are not likely to depart much from its expected return has little risk.
A security, whose returns from year to year are quite volatile, has higher risk.
Suppose you buy a stock from which you expect these hypothetical returns
A third of the past years went with normal economic conditions, a third of them with rapid growth and a third of them with recession.
“Expected return = 1/3(0.30) + 1/3(0.10) + 1/3(–0.10) = 0.10.”
Yearly returns will be quite variable, from 30% to -10% , so we need to calculate how much it varies.
The greater the variance, the greater the possibilities for disappointment.
Symmetric distribution
2/3 of monthly returns fall within 1 stddev.
95% of monthly returns fall within 2 stddev.
Mean is about 2.5%
Std.Dev: 4.5%
-2% to 7%, 1 stddev
-6.5% to 11.5%, 2 stddev
Higher standard deviation
Higher the risk
Higher the returns
or maybe not.All investors are risk-averse.
High returns
Guaranteed outcomes.
The theory tells investors how to combine stocks in their portfolios to give them the least risk possible, consistent with the return they seek.
Conjured in 1950s by Harry Markowitz
The math behind is complex.
Risky portfolios can be put together in such a way that the portfolio as a whole could be less risky than the individual stocks in it.
Suppose an island economy with only two businesses.
Large resort with beaches, tennis courts and a golf course.
Umbrella manufacturer
Weather affects them both.
Suppose that on average, one-half of the seasons are sunny and the other is rainy.
An investor(with 2$) who bought stock in the umbrella manufacturer earns 50% half of the time, loses 25% half of the time.
Earns 12.5% on average.
Now suppose instead of buying only one security, he diversifies and puts half of his money(1$) in the umbrella manufacturer and half of his money(1$) on the resort.
In sunny seasons, one dollar investment returns 50 cents from the resort and loses 25 cents from the umbrella business.
In rainy seasons, the opposite happens, and you get 12.5% on average.
| Umbrella Manufacturer | Resort Owner | |
| Rainy Season | 50% | -25% |
| Sunny Season | -25% | 50% |
We eliminated the risk of weather
Our expected returns are hypothesized with the premise of exactly 6 months of sun and 6 months of rain.
The reality would be quite different.
Negative covariance
As long as there is some lack of paralellism in individual companies, we can reduce risk with diversification
With perfect negative relationship (one company does perfect when the other does very bad) diversification can totally eliminate risk.
Of course it's not this easy.
There may be a recession and people may not buy vacations or umbrellas.
Perfect negative relationship is almost nonexistent.
If you buy Ford Motor Co. and its major supplier of tires in a stock portfolio, this diversification may not help you that much.
If Ford's sales go bad, Ford won't buy that many tires, so the supplier goes bad.
High covariance/High correlation
If you buy Ford Motor Co. and a government contractor in a depressed area, diversification may help.
If consumer spending is down, Ford's sales will be down and unemployment will be up.
Government tend to give out contracts to depressed areas in times of high unemployment
Can there be too much of a good thing? - William Shakespeare
Is this really really magical?
Nope.
Buying only US stocks reduces the risk 60%
Buying international stock reduces it even more (because of more diverse portfolios)
However after a certain point, it converges into a single risk value.
You have to recognize that the world has changed considerably since Markowitz first put his theory in writing.
Not every economy reacts the same way.
Oil price increase
Bad for Europe, Japan, even US
Not really bad for the Middle East
S&P 500 Index and Morgan Stanley EAFE(Europe, Australasia and Far East) Index of developed foreign countries
Overall portfolio risk is reduced by the addition of a small amount of riskier foreign securities.
Good returns from Japanese automakers balance the poor returns of US automakers
Dollar balances out the European recession.
Globalization increases the correlation coefficiency
Diversification tends to have less effect in general.
Diversification helped balance out the investments in 'the lost decade'
Thank you for sticking with me the whole time.
In portfolio investing, invest diversely between companies with low correlation.
Diversification in investing tends to reduce risks related to your investment.


What are ensemble methods?
Ensemble methods refer to an machine learning algorithm that is combination of classifiers to tackle a classification problem by using the results from all these classifications to determine a label (usually by a vote).
A vote is a majority based voting mechanism. For instance, of 10 classifiers, 4 voted for label X and 6 voted for label Y, the voting result is label Y has 6 > 4.
Why is it useful?
It can be better than using a single classifier in many cases. Suppose there are 4 independent classifiers classifying two labels X and Y, then observe that a data instance with label Y predicted by these classifiers:
| Classifier | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| Label | Y | X | Y | Y |
Even though classifier 2 predicted X (which is wrong), through voting, the final result is still Y (3 Y > 1 X).
Thus, the result is wrong only if more than half of the classifiers are wrong.
When does it fail?
If the error rate is larger than 0.5 for each classifier, then the classifiers will be correct only if more than half of the classifiers are correct. The net result is that the set of classifiers predict more wrong answers, in this case do not use ensemble methods.
What is the error rate of the ensemble method, assuming the error rate of each classifier is 0.15?
It is given by the general formula of:
error_rate_of_ensemble = 0
for i in [floor(n/2)+1, n]:
error_rate_of_ensemble += nCr(i, n) * error_rate^i * (1 – error_rate)^(n-i)
where n = number of classifiers,
error_rate = error rate of each classifier (assumed equal here)
In our case, if the error rate of a single classifier is 0.15, the error rate of the ensemble would be only 0.01.

Originating from the Innovation Labs at New York Institute of Technology, a group of 4 qc-interested engineering & comp sci students sat down to found NYIT's very first quantum computing club in 2019.
Desiring to expand their knowledge beyond the institution, The Quantum Research Group is a collective of students, professors, researchers, and industry experts across all disciplines in NYIT and New York City using an interdisciplinary lens to tackle the future's biggest and most exciting problems. This isn't just a computer science/engineering group, this is a group that needs everyone.
And, indeed, everyone will need quantum computers :)

What is Quantum Computing?
Quantum computing is a deviation from the classical computational techniques we've become accustomed to, otherwise known as binary, or the 1's and 0's your computer reads whenever you type a letter on the screen. When you press a key on your keyboard,
an encoded electrical signal is transmitted from the keyboard to your computer's processor; the signal is then decoded into raw 1's and 0's to induce a command,
that command is then translated into the material you see on your monitor. Lengthy explanations aside, as you've witnessed previously, Quantum computers are exponentially more powerful than any regular computer you could possibly dream up, this is solely due to the fact that they follow Quantum physics, which essentially means that binary is rendered obsolete by an entirely different playing field's standards. Quantum computers use a little something called qubits.
Qubits are the bread and butter of quantum computing; being the sole reasoning behind the exponential performance leap generated by this technological pariah because of the physical principal with which they are associated with, known as superposition.
Superposition is otherwise known as the conjoined natural states of an object occuring at the same time. Say a cat was falling off a building in a fetal-esque position, but when it lands it goes prone, basically with superposition that cat assumes both of those positions in time at the same instance, thus defying what most normal humans have come to know as real world physics. Since a qubit can be both a one and a zero this results in more calculations being done in a smaller package, as well as less power consumption necessary to switch 1's to 0's and vice versa. All in all, qubits are the quintessential element of quantum physics; although we are still in the infantile stages of quantum computational techniques and application, the race to the future definitely looks promising, but it doesn't come without its hurdles. -Justin C

On the quest to learning more about the universe and improving humanity through scientific knowledge, I'll be accumulating notes and research on quantum computing here. I'll try to cover an ongoing knowledge base of quantum development, a history of what has already transpired to lead us to the exciting times in scientific discovery we have now, as well as the trials of quantum computing we have ahead.
Coming from a computer science background, I will ultimately be interested in programming applications effectively using quantum computation methods to optimize a plethora of issues in our society.
Run around with Queen as our beloved corgie attempts to gather quantum data using the best machine learning it can given the times!
Where to next?
The sky is the limit
Quantum computing is predicted to become the next trillion dollar industry, with large stakes in the medical, financial, and scientific fields already in the works. Here we have a computational pariah, an instrument that can lead humanity to new heights, a device that can calculate something that would take a traditional computer until the heat death of the universe to calculate, in mere minutes. Everybody wants a piece of the pie, but is the pie really as sweet as it seems?
Join us on our journey, and we may all find out if quantum truly is the final frontier for humanity.

Back in the days, I released a Mac AppStore application called «Manual».
It was a simple GUI front-end for the UNIX manual pages.
Marty Turner contacted me on Twitter, because he wanted to know if the app was still available somewhere. As it wasn't available anymore, he kindly proposed to maintain it.
So I put the whole project on GitHub (https://github.com/macmade/Manual), and gave hime write access.
I must say very pleased to see people getting interested in those «old» projects and wanting to maintain them.
Thanks Marty : )


What is wrong with the following nested for loop?
for (int i = 0; i < 3; i++)
{
for (int i = 0; i <= 5; i++)
{
// body of the loop here
}
}
Both the internal and the external loop define variables with the same name i
- The nested for loop uses "<=" while the external for loop uses "<"
- The code i++ will cause a syntax error
- Nothing is wrong with these nested for loops
There are not hints for this question


Hi! I’m Nawar Yossef I'm a fullstack Javascript developer from Atlanta, Georgia. I use web technologies to make awesome applications. At the moment, I enjoy working with Node.js and React
View My Work
I am sure you just want to check my work out, so I'll be quick. I’m a concert pianist turned web developer. I began learning
web development one year ago. I started off with learning the basics of HTML/CSS, JavaScript, Ruby, C++ then I
decided to focus on learning Javascript and front end frameworks.
I have always had a passion for classical music and a love of technology. At a young age, I chose to focus on
establishing a career as pianist and film music composer. At the same time I continued to satisfy my tech interests.
I believe that programming is an art form and that there is a great parallel between music composition and web
development. That is the ability to create and shape something out of nothing.
Outside of my digital life I have a number of other interests as well. I love watching and playing tennis, hiking
and enjoying nature, and spending time with my beautiful wife and good friends.
I’m a passionate javascript programmer who specializes in front-end development. I have a powerful team spirit, a creative
mind and a great work ethic. I believe in pretty designs and clean coding, and take pride in writing the kind of
code that others can read and collaborate on.
I enjoy working with Photoshop and convert designs to high-performance code whilst respecting the designer’s compositions.
I Use modern techniques to build web applications and websites that look great on the browser or on the phone.
The mobile compatibility is one of my main concerns so I’m always focused on making my applications work nice and
smoothly on mobile devices.
I’m constantly learning new technologies and thriving to improve my skills. I spend most of time reading books,
attending workshops, and blogging about my experience.

--- layout: example title: Demo ---
Instead of using tab to navigate through elements on this page, try using + on the keypad. Also try reverse navigation with shift-+.
In this demo, most of the elements are plussable, but the normal use case is to enable plussing where users input mostly numbers (as in quantities, zip codes, short date formats) using the keypad. The normal tab key still works as usual.
Laptops may not have physical keypads, but instead it is emulated with the Fn key (or similar). PlusAsTab is not targeted at laptop users. It is possible to use an external/separate USB keypad though. Perhaps laptop users would be more interested in the PlusAsTab demo that uses enter as tab? The key is configurable, and multiple keys are supported - read more on the project page.


UK manufacturing sector continues decline despite some signs of life
by Harry RobertsonUK manufacturing output continued to fall in November, a closely-watched survey has shown, but there were signs that the sector’s fortunes could be improving.
Orders picked up by more than expected from the decade low seen in October. But they stayed well below their historical average, the CBI said in its latest industrial trends survey.
Britain’s factories have suffered in 2019 as Brexit uncertainty has put off investment and the US-China trade war has dented global demand.
The manufacturing sector officially contracted in the second quarter and flat-lined in the third, putting it close to recession.
The CBI survey today painted a mixed picture of the sector. Output volumes fell at a similar pace in October, with output expanding in only five out of 17 sub-sectors.
Yet the survey of 307 manufacturers found that total order books improved compared with October.
More manufacturers reported a fall in orders than a rise, taking the balance to minus 26, but the figure was better than economists had predicted. It was also a significant improvement on October’s minus 37 score, which was the worst in almost a decade.
Anna Leach, CBI deputy chief economist, said: “While the thick fog of uncertainty from a no-deal Brexit has lifted somewhat, the manufacturing sector remains under pressure from weak global trade and a subdued domestic economy.”
She said: “Order books remain below average, and output volumes continue to fall. When taking into account the deteriorating outlook for manufacturing globally, it’s clear that the outlook for the sector remains precarious.”
In the run-up to the UK General Election on 12 December, both main parties have promised significant spending increases on infrastructure that could boost the sector.
Leach said that on top of this, “ratifying a Brexit deal and moving on to build a vibrant future relationship with our biggest trading partner, based on frictionless trade, will be vital”.

plt(...,'moveCB',s); Evaluate string s whenever the cursor is moved. This callback function can be overwritten by the the cursor command plt('cursor',cid,'set','moveCB',fcn) which is described in more detail in the cursor commands section. The moveCB is not really an axis property, but is included in this section because of the parallels with the above axisCB parameter. As with the axisCB parameter, you may use function handles for this parameter (see above). |
ENApre |
plt(...,'ENApre',[ENAx ENAy]); |
AxisLink |
plt(...,'AxisLink',m);
tells plt to start with the left/right axes linked if m=1 or unlinked
if m=0. For more details, see the
right hand
axis section. |
+AxisProp
|
If a property name is prefixed with a
+ or a - character then the property value will be
applied to the left or right hand axis
respectively.
If a property name is prefixed with a
> ,
< or a
. character then the property value will be
applied to the left hand axis label, right hand axis label, or x axis label
respectively. plt(...,'+Ycolor',[0 0 1],'-Yscale','Log'); In this example plt will assign the value [0 0 1] (blue) to the Ycolor property of the main (left hand) axis, and it will apply the value 'Log' to the Yscale property of the right hand axis. The plus and minus signs are called a property prefix characters and are required so that plt knows which axis you want to modify. plt(...,'>FontName','Lucida Handwriting'); In this example the font used for the right hand axis label is changed to Lucida Handwriting. More than one property prefix character may be included in front of a property name. For example: plt(...,'+<.FontSize',13); In this case, the font size for the left hand axis tick labels, the left y-label, and the x-label are increased to 13.
The example
demo\pub.m demonstrates the use of these prefix
characters.
Note that if a property name appears without one of these 5 leading prefix
characters (<>.+-), then property value will
be assigned to all the lines that have
been defined earlier in the argument list. |
SubPlot |
plt(...,'SubPlot',v);
Normally plt puts all the defined traces on a single plot (which may
have left and right hand y-axes) that fills most of the figure area. However
with the SubPlot parameter you can tell plt to create several plots in the
same figure. All the plots are arranged in either one or two columns. All
plots in a column must use the same x-axis. The subplot in the lower left
corner has a special designation (the main plot) since that is the only plot
that includes a traceID box. Also some of the cursoring features are only
available on the main plot (peak/valley finder, delta cursors, expansion
history, the Mark/Zout/LinX/LinY tags, and the x-axis slider. Each subplot
however has its own y-axis cursor readout. These cursor readouts are easy to
identify since its background color matches the trace and axis colors. The
full panning and zooming features of plt are supported for each subplot. When
any subplot is panned or zoomed in the x-axis, all the x-axis limits of all
the other subplots in the same column are set to match the newly chosen
values. Single column Dual column plt(x,y,'SubPlot',[100 -60 100],'Right',[2 3]); The subplot parameters tells plt to create two plots both of which fill the entire height available in the plotting area of the figure. The left (main) plot fills 60% of the width with the second plot filling the remaining 40%. Since six traces are defined, the first five traces (a thru e) appear on the main plot and the last trace (f) appears on the right plot. Since the TRACEid parameter was not included, the trace ID box next to the main plot will contain the default trace labels (Line1 thru Line5). To label the traces more informatively, a parameter such as 'TRACEid',{'a' 'b' 'c' 'd' 'e'} could be added to the plt argument list. Since the 'Right' parameter was included, the main plot will include both right and left axes, with the 2nd and 3rd traces (b and c) on the right and the remaining three traces (a,d,e) on the left. The left and right axes will be separated by enough space to leave room for the axis labels, and this space will be increased when the 'Right' parameter is used so that there is room for an axis label on the right side of the main (i.e. left) axis. However if you would like to increase or decrease the amount of space between the two columns you can do this by modifying the width argument. As an example, suppose as above you still want the left plot to occupy 60% of the available width, but you want to increase the spacing between the two axes by 2.3% of the figure window width. To do that you would use 'SubPlot',[100 -60.023 100]. And for another example, if you wanted to decrease the spacing by 3% of the figure width you would use 'SubPlot',[100 -60.97 100]. plt(x,y,'SubPlot',[50 30 20 -55 70 20]); Three plots will be created in the left column which fills 55% of the width of the plotting area. The main plot on the bottom (containing traces a & b) fills 50% of the height, the middle plot (trace c) fills 30% and the top plot (trace d) fills the remaining 20% of the height. Two plots are created in the right column which fills the remaining 45% of the width. The lower of these (trace e) fills 70% of the height, and the upper (trace f) fills 20%, with the upper 10% remaining blank. Note that both traces in the main plot use the left-hand axis since no 'Right' parameter was given and no limits or labels were specified for the right-hand axis. (With this many subplots it's best not to use a right-hand axis since it makes all the subplots significantly narrower to make room for the right-hand axis ticks and labels.)
plt(x,y,'LabelX',{'meters' 'pascals'},'Ylim'{[0 5] [0
.1]}); Even though the subplot argument is not included here, plt
will split the plot horizontally as if you had included
'SubPlot',[100 50 100]
in the argument list. This is because two different x-axis labels are
specified with the 'LabelX' parameter and the only time this is needed is
for two column subplots. The right column plot will contain trace f and the
left column (main) plot will contain traces a thru e. Since two y-axis
limits are specified, plt will put both left and right axes on the main
plot. In this example the 'Right' parameter is not included, so plt will
default to putting the last trace of the main plot (trace e) on the right
axis with the other four traces on the left axis. (Be careful not to confuse
the concepts of the right and left axes of the main plot, with the right and
left columns of subplots.) Also note that the 'Ylim' parameter only
specifies limits for the main plot and never for any of the other subplots.
If you need to set the y-axis limits for the other subplots, use the set
command with the axis handles obtained from getappdata(gcf,'axis'). |
SubTrace |
When using subplots, it is important to understand that the default behavior
is to allow only a single trace on each subplot except for the main axis
(lower left). The main reason for this is to allow plt to provide a simple
cursoring mechanism which allows every trace to be cursored. However there
are two situations where you may want to change this default behavior. The
first is where cursoring is disabled (usually because the plot is too be
used for publication instead of for data exploration). Since cursoring is
not an issue, there is no reason you must stick with the default behavior
for assigning the traces to the axes. The second plot in the script
demo\pub.m is an example of how the
SubTrace parameter might by used in this
situation. The second situation where you might want to use this parameter
is when you plan on modifying the cursor behavior to make sense for the
particular trace arrangement you have in mind. This requires a detailed
understanding of plt's cursoring commands, but is doable when the trace
configuration and desired cursoring scheme are reasonably simple.An example
of this second situation can be found in the script
demo\weight.m. There are two ways to use this parameter to assign the traces to the various subplots. For either method you must know how plt numbers the axes. Axis number one is always the main axis (lower left). Then axis two is the one directly above the main axis and axis three is the one above that, continuing to the top of the left column. Then the lowest axis of the second column (if it exists) is assigned to the next number, and continuing upwards as before. Finally after all the subplots have been assigned a number in this manner, the right hand axis of the main plot (if it exists) is assigned to the next higher integer. Suppose for example, you have 4 axes and 9 traces and that you want to put two traces on each of the first 3 axes and then put the remaining 3 traces on the last axis. You could do this with 'SubTrace',[2 2 2 3]. Instead of specifying how many traces are on each axis, an alternate way of doing this is to specify which axis each trace goes on. So an equivalent to the previous parameter you could use 'SubTrace',[1 1 2 2 3 3 4 4 4]. Of course this second method is always going to be longer than the first method, so you would likely only use it if you needed to assign the traces to the axes in a different order, for example 'SubTrace',[1 2 3 1 2 3 4 4 4]. |

EQ is: Emotional Intelligence quotient
EQ is all about how we relate to others and to the world around us.
Being able to Identify emotions, being able to relate to other people’s experiences and being able to talk socially with others are vital skills both in and outside of the workplace.
It allows us to develop empathy and to see where people are coming from. EQ is more on the side of social and environmental intelligence rather than logistical reasoning.
EQ can identify team players, leaders and creative thinkers.
IQ is: Intelligence Quotient
IQ is the more about the logistics of the brain. Visual processing, working memory, math skills and fluid and quantitative reasoning belong to IQ.
For many years, IQ was the preferred way to measure intelligence through standardized tests and they started testing earlier and earlier.
This was the only test that confirmed how “smart” you were and how you would fare academically and in your career.
In the workplace, IQ is crucial for analyzing problems, research and development and organization.
To ask which one is better is inaccurate as we need both in order to be a well-rounded intelligent person.
Both can be learned through a process called Neuroplasticity. When we learn something new, we create new connections in our brains via neural pathways.
The more we use those pathways, the stronger they get allowing us to essentially rewire our brains, thought patterns and behaviours.
