History of web Development
A Brief History of Web Development
The rise of the internet within mainstream culture is largely correlated with its history as a visual medium. Like many other computer systems and applications, it took a graphic interface to get the general population to start to understand the internet’s potential. The personal computer would not have proliferated throughout our households and work environments without the display monitor, and still did not become widely used until electronic spreadsheets, word processors and video games started attracting users. Similarly, users did not start buying into the World Wide Web until the visual-oriented web browser started coming into its own in the early 1990s. And since that time, even though there have been dramatic improvements in web technology and aesthetics, some of the earliest web design techniques have persevered throughout the years.
The Old Web
The idea of the internet had existed in some form for at least a half a century before it finally became a common household utility in the 1990s. Conceived in the 1980s, the World Wide Web gained significant traction with the introduction of the Mosaic browser in 1993. Shortly thereafter, businesses began recognizing the web’s commercial potential, as network infrastructure grew to accommodate what would prove to be a massive influx of online activity. Then the tech bubble grew and burst, the survivors of which (Google, Amazon and the like) went from being key tech influencers to veritable corporate giants within about a decade.
In 1989, Tim Berners-Lee (then a fellow at the CERN Laboratory in Europe) outlined his concept of a computer platform that could facilitate collaboration among researchers who are based in different parts of the world. This led to the invention of the Hypertext Markup Language (HTML) in 1990. Strongly based on the Standard Generalized Markup Language (SGML), HTML became the fundamental building block of the World Wide Web, and remains at the core of its coding and infrastructure. The standard enabled coders with the ability to organize web page layouts that could be understood and interacted with over interconnected networks. (For more on the development of the web, see The 6 Programming Languages That Built the Internet.)
Prior to the Mosaic browser, much of the web’s presentation consisted of text and tables. Although not the first browser, Mosaic innovated the format by displaying text together with images in a way that defined a path for the future of web design, and served as the World Wide Web’s killer app. Experiments ensued in the form and function of web page elements. From menu hierarchies to fonts to color schemes, web design grew into an art form that blended tech savvy with aesthetic sensitivity.
Conclusion
Since the advent of the Mosaic browser and the subsequent rise of the web interface, internet technology has thrived through at least two major economic bubble bursts – in 2001 and in 2008. The latter collapse, while concurrent with the larger housing crisis, also marked the age of a new killer app – the mobile operating system. And in the years since then, the web page has gradually changed shape to accommodate its various new contexts. Now, the mobile app could eventually even displace the web page as we know it. But it still derives much of its basic properties from design concepts innovated through the discipline of web development.

Maggert leads, Langer making bid for season title
PHOENIX (AP) - Jeff Maggert shot a 6-under 65 on Friday to increase his lead to four strokes in the Charles Schwab Cup Championship, with Bernhard Langer second in a bid for his record sixth PGA Tour Champions season points title.
Maggert birdied three of the first four holes in a front-nine 31 and capped the bogey-free round with a birdie on the par-4 17th in perfect conditions at Phoenix Country Club. He had a 14-under 128 total.
The 55-year-old Texan entered the season-ending event 34th in the Charles Schwab Cup standings, just three spots from failing to qualify. He won three times on the PGA Tour and has five senior victories, one in 2014 and four in 2015.
Langer closed with a double bogey after hitting his approach into the water on the par-5 18th. Coming off a playoff loss to Colin Montgomerie on Sunday in California, Langer is third in the standings behind Scott McCarron and Jerry Kelly.
To take the season title, the 62-year-old German star needs to win the event and have McCarron finish in a two-way tie for fifth or worse and Kelly finish in a two-way tie for second or worse. McCarron (71) and Kelly (74) were tied for 25th at 2 under.
Retief Goosen, fifth in the standings, had his second straight 67 to join Brandt Jobe (66) and Marco Dawson (67) at 8 under.
Miguel Angel Jimenez (70) was another stroke back with Joe Durant (66), Wes Short Jr. (67) and Steve Flesch (70).

@Kevin Buzzard, have you seen @David Michael Roberts attempt to summarise the latest disagreement between Mochizuki and Scholze? <https://thehighergeometer.files.wordpress.com/2018/09/mochizuki_final1.pdf>. It's very much about whether such replacements were valid or not.
@David Michael Roberts Did you get any answer from either side?
Not yet. I guess it's just percolating through social media at the moment.

If a function is defined as a friend function of a class, then that function can access all the private and protected data.
To make a function as a friend of a class, it is declared inside the class either in private or in public section with keyword friend before its declaration as follows.
class Temperature
{
int celsius;
public:
Temperature()
{
celsius = 0;
}
friend int temp( Temperature ) //declaring friend function
};
Here temp is a friend function of the class Temperature. So, it can access all the private and protected members of the class.
Let's see an example.
#include <iostream>
using namespace std;
class Temperature
{
int celsius;
public:
Temperature()
{
celsius = 0;
}
friend int temp( Temperature ); // declaring friend function
};
int temp( Temperature t ) // friend function definition
{
t.celsius = 40;
return t.celsius;
}
int main()
{
Temperature tm;
cout << "Temperature in celsius : " << temp( tm ) << endl;
return 0;
}
Here we declared a function 'temp' as the friend function of the class 'Temperature'. In the friend function, we directly accessed the private member celsius of the class 'Temperature'.
When the first statement of the main function created an object 'tm' of the class 'Temperature' thus calling its constructor and assigning a value 0 to its data member celsius.
The second statement of the main function called the function 'temp' which assigned a value 40 to celsius.
We can also have the same friend function of two classes as shown in the next example.
#include <iostream>
using namespace std;
class B; //declaration of class B
class A
{
int value;
public:
A()
{
value = 5;
}
friend int sum(A, B); // declaring friend function
};
class B
{
int value;
public:
B()
{
value = 3;
}
friend int sum(A, B); // declaring friend function
};
int sum( A v1, B v2 ) // friend function definition
{
return (v1.value + v2.value);
}
int main()
{
A a;
B b;
cout << "Sum : " << sum( a, b ) << endl;
return 0;
}
In this example, we declared sum() as a friend function of the classes A and B. So, this function can now access the private and protected members of both these classes. The objects of both the classes are passed into as an argument to the function.
First, we created an object for both the classes, thus calling their respective constructors and initializing the values of their respective data member value to 5 and 3. The function 'sum' then returned the sum of the data members of the two classes by calling the data members of the two classes by their respective objects.
Friend Class
We can also make a class a friend of another class. In that case, all the member function of the class declared as friend become the friend functions of the other class.
Let's see how to make a class a friend of another.
class A
{
friend class B;
};
class B
{
};
Class B is declared as a friend of class A in the above code. So, now all the member functions of class B became friend functions of class A.
Let's see an example of a class friend.
#include <iostream>
using namespace std;
class Square
{
friend class Rectangle; // declaring Rectangle as friend class
int side;
public:
Square ( int s )
{
side = s;
}
};
class Rectangle
{
int length;
int breadth;
public:
int getArea()
{
return length * breadth;
}
void shape( Square a )
{
length = a.side;
breadth = a.side;
}
};
int main()
{
Square square(5);
Rectangle rectangle;
rectangle.shape(square);
cout << rectangle.getArea() << endl;
return 0;
}
We declared Rectangle as a friend class of Square. Thus now, all the functions of Rectangle can directly access any private member of Square.
In the main function, the first statement created an object 'square' of the class Square, thus calling its constructor and assigning 5 to its data member side.
The second statement in the main function created an object 'rectangle' of the class Rectangle.
In the third statement, 'rectangle' called the function shape() with the object of the class Square passed as its argument. In the 'shape()' function, the value of 'side' (private data member of Square) was assigned to length and breadth. The fourth statement called the function 'getArea' of the class Rectangle.
Class Members as Friend
We can also make a function of one class as a friend of another class. We do this in the same way as we make a function as a friend of a class. The only difference is that we need to write class_name :: in the declaration before the name of that function in the class whose friend it is being declared. The friend function is only specified in the class and its entire body is declared outside the class. It will be clear from the example given below.
class A; // forward declaration of A needed by B
class B
{
display( A a ); //only specified. Body is not declared
};
class A
{
friend void B::display( A );
};
void B::display(A a) //declaration here
{
}
Let's see its example.
#include <iostream>
using namespace std;
class A; // forward declaration of A needed by B
class B
{
public:
void display(A obj); //no body declared
};
class A
{
int x;
public:
A()
{
x = 4;
}
friend void B::display(A);
};
void B::display(A obj)
{
cout << obj.x << endl;
}
int main()
{
A a;
B b;
b.display(a);
return 0;
}


Shift in frequency (sine waves)¶
Description¶
This function simulates a sum-of-sine signal \(y_t=\sin(2\pi f_1 t)+\sin(2\pi f_2 t)\) where \(t=0,\dots,T-1\). The frequency vector \([f_1, f_2]\) alternates between \([0.075, 0.1]\) and \([0.1, 0.125]\) at each change point index. Gaussian white noise can be added to the signal.
Usage¶
Start with the usual imports and create a signal.
import numpy as np
import matplotlib.pylab as plt
import ruptures as rpt
# creation of data
n, dim = 500, 3 # number of samples, dimension
n_bkps, sigma = 3, 5 # number of change points, noise standart deviation
signal, bkps = rpt.pw_wavy(n, n_bkps, noise_std=sigma)
rpt.display(signal, bkps)
Code explanation¶
-
ruptures.datasets.pw_wavy.
pw_wavy
(n_samples=200, n_bkps=3, noise_std=None)[source]¶ Return a 1D piecewise wavy signal and the associated changepoints.
- Parameters
n_samples (int, optional) – signal length
n_bkps (int, optional) – number of changepoints
noise_std (float, optional) – noise std. If None, no noise is added
- Returns
signal of shape (n_samples, 1), list of breakpoints
- Return type
tuple


PNW-based musician Joe Waine has covered -- from what he can remember -- a song by modern electronic music's most famous musician.
But, which musician? Think you could take a guess?
Well, he is a controversial vegan.
Need another hint? All right.
He claims that he shaved Natalie Portman's head to look more like him when he went to Harvard with her or something because they were both auditioning for Black Swan but she eventually got the part and he was really pissed because he's always loved ballet.
I think you might have an idea.
At any rate, Joe Waine will be releasing his new album, Fat Dreams Of Italy, in the coming months. Talented multi-instrumentalist Owen Whitcomb and mysterious, brutalist music producer Brenan Chambers' influences are ripe throughout Fat Dreams. Other album credits include: the certifiably handsome Will Segerstrom on bass; the stately Joel Harrison on percussion; as well as engineering by the talented-and-fanciable Dylan Wall.
In addition to digital and tape releases of the album, he will be selling hats and shirts. One-hundred percent of the proceeds will go to charity.
Listen to his song 'Porcelain From What I Can Remember' on Bandcamp today.

TG-Data aims to provide guidance to the Data Distribution Centre (DDC) on curation, traceability, stability, availability and transparency of data and scenarios related to the reports of the IPCC. Together with the DDC, the Task Group facilitates the availability and consistent use of climate change-related data and scenarios in support of the implementation of the IPCC’s programme of work.
TG-Data replaces the Task Group on Data and Scenario Support for Impact and Climate Analysis (TGICA) whose mandate was to facilitate the distribution and application of climate change related data and scenarios to enable research and sharing of information across the three IPCC Working Groups.
At its 47th Session on 13-16 March 2018, the IPCC adopted Decision IPCC-XLVII-9 where TGICA was renamed to Task Group on Data Support for Climate Change Assessments (TG-Data) with new Terms of Reference for TG-Data as well as Guidance for the Data Distribution Centre (DDC).
New members of TG-Data were selected during the 56th Session of the IPCC Bureau held in Geneva in March 2019.
The Task Group will be co-chaired by David Huard from Canada and Sebastian Vicuna from Chile. The other members are:
The Data Distribution Centre (DDC) provides climate, socio-economic and environmental data, both from the past and also in scenarios projected into the future. Technical guidelines on the selection and use of different types of data and scenarios in research and assessment are also provided. The DDC is designed primarily for climate change researchers, but materials contained on the site may also be of interest to educators, governmental and non-governmental organizations as well as the general public.
To access the DDC, click here.
The Emission Factor Database (EFDB) is a project supported by the National Greenhouse Gas Inventories Programme (NGGIP), which is managed by the IPCC Task Force on National Greenhouse Gas Inventories (TFI).
EFDB is intended to be a recognized library, where users can find emission factors and other parameters with background documentation or technical references that can be used for estimating greenhouse gas emissions and removals. The responsibility for using this information appropriately remains with the users themselves.

INDEX_DESC The INDEX_DESC hint specifies that the optimizer should choose an index scan to access the specified table. The syntax of this hint is as follows: /*+ INDEX_DESC( table index [ index .. index ] ) */ The INDEX_DESC hint may contain one or more indexes. This hint is similar to the INDEX hint except that if the statement specifies an index range scan, the entries are scanned in descending order of their indexed values. ROWID As you know, you do not necessarily have to perform a table scan by row ID. If you want to do a table scan by row ID, use the ROWID hint to specify that the optimizer should choose a table scan by row ID to access the specified table. The syntax of this hint is as follows: /*+ ROWID( table ) */ This hint specifies the use of a table scan by ROWID, even though an index may be present for this table and the index key is specified in the WHERE clause. USE_CONCAT The USE_CONCAT hint forces combined OR conditions in the WHERE clause of a query to be transformed into a compound query using the UNION ALL set operator. Typically, this transformation is done only if the cost is cheaper with concatenation than without it. The syntax of this hint is as follows: /*+ USE_CONCAT */ Join Orders The following hint is used to specify join orders that take advantage of information you know about your data to improve the performance of the joins. ORDERED The ORDERED hint caused the execution plan to join tables in the order they are specified in the FROM clause. The syntax of this hint is as follows: /*+ ORDERED */ Because you know your data better than the Oracle optimizer, you may be able to specify the order of the join to make better choices for the inner and outer tables than the optimizer can. The join operations mentioned in the following section can be used with the ORDERED hint. Join Operations The following hints are used to specify join operations and to take advantage of information you know about your data to improve the performance of the joins. When specifying a join operation for an SQL statement, the table to be joined must be specified exactly. If the table is accessed with an alias, you must specify the alias. The USE_MERGE and USE_NL hints must be used with the ORDERED hint. USE_MERGE The USE_MERGE hint causes the execution plan to join each specified table with another row source using a sort-merge join. The syntax of this hint is as follows: /*+ USE_MERGE ( table ) */ You can use this hint with the ORDERED hint as follows: /*+ ORDERED USE_MERGE ( table ) */ In this syntax, table refers to a table to be joined to the row source that results d1b from joining other tables in the join order using a sort-merge join. USE_NL The USE_NL hint causes the execution plan to join each specified table with another row source using a nested-loops join. The specified table is used as the inner table. The syntax of this hint is: /*+ USE_NL ( table ) */ In this syntax, table refers to the table to be used as the inner table of the nested-loops join. Parallel Query HintsThe following hints are related to the Oracle Parallel Query option. As I have said many times in this book, I am a great fan of the Parallel Query option: you can achieve great results when you use it. CACHE The CACHE hint specifies that the blocks retrieved for the table in the hint are placed at the most-recently-used end of the LRU (least recently used) list in the buffer cache when a full-table scan is performed. When a full-table scan occurs, the entries are usually put on the end of the LRU to age more quickly. This is done because most of the data read in a full-table scan is usually discarded. The CACHE hint can be useful if most of the data in a full-table scan is used. The syntax of this hint is as follows: /*+ CACHE ( table ) */ Alternatively, you can use the CACHE hint with the FULL hint: /*+ FULL( table ) CACHE ( table ) */

BELOVED (Touchstone) Starring: Oprah Winfrey, Danny Glover, Thandie Newton, Kimberly Elise, Beah Richards. Screenplay: Akosua Busia, Richard LaGravenese and Adam Brooks, based on the novel by Toni Morrison. Producers: Edward Saxon, Jonathan Demme, Gary Goetzman, Oprah Winfrey and Kate Forte. Director: Jonathan Demme.  Reviewed by Scott Renshaw.
 Its opening minutes portend something quite different: two silent exterior shots, one tracking through a graveyard and the other establishing a rural Ohio home, shift to a scene of sheer supernatural terror. Inside the home, a woman named Sethe (Oprah Winfrey) and her three children cringe in fear as the family dog spins through the air, an eye torn out and a leg broken by an anguished spirit. We learn that the entity is the ghost of another daughter, who has haunted the house long enough for the latest event to drive the two boys away from home. So much for earnest dignity; this is a prestige release as American gothic horror film.
That shouldn't be terribly surprising coming from director Jonathan Demme, who turned 1991's THE SILENCE OF THE LAMBS into an Oscar-winning prestige release. Yet this is no more a conventional thriller than it is a conventional epic drama, though it incorporates elements of both. The bulk of the film takes place eight years after that prologue sequence, when the arrival of two strangers shake up the isolated lives of Sethe and her remaining daughter Denver (Kimberly Elise). Paul D (Danny Glover), a former slave with Sethe on the Sweet Home plantation, provides a companionship Sethe hasn't known for years. The other arrival is more mysterious, a child-like woman calling herself Beloved (Thandie Newton). Their interaction, interwoven with selected flashbacks, turns BELOVED into a complex ghost story in which the ghosts take on many forms, attacking both from without and from within.
It's what BELOVED does with the idea of a ghost story that made Toni Morrison's novel so powerful, and makes Demme's film so gripping. The true horror in the story is Sethe's past, the painful and humiliating past of all slaves which involved so many horrifying events. Most film-makers would have taken those events and shown them off with sincere indignation. The images created by Demme and cinematographer Tak Fujimoto are jittery and chilling, designed more to invade the sub-conscious than to inspire tight-lipped head-shaking. Beloved appears initially as a sort of earth-spirit, covered with insects; the bright ribbons of a family celebration become a lingering symbol of decayed hopes. With Oprah Winfrey effectively conveying Sethe's hollow-eyed resignation, BELOVED shows how a tormented past can corrupt the present to the point that it feels perpetually haunted, holding meaning only as a constant reminder of unforgettable evils.
If BELOVED had intended merely to shock and dismay, it would have been a very shallow and disspiriting experience. Instead, it becomes a call to the living to dare existing in the present, conveyed through two supporting characters marvelously performed. Kimberly Elise takes Denver on a journey from trying to re-capture her own past -- treating Beloved both as her own child and as the sister she never knew -- to shaking herself and Sethe into a desire for survival. Stronger still is the bright angel of the deceased Baby Suggs (Beah Richards), Denver's paternal grandmother and the spiritual leader of her community. Her glorious sermons, which call all around to celebrate their bodies even as they acknowledge sorrow, provide stirring punctuation for this tale. As counterpoint to Sethe's inability to forgive herself, Baby Suggs enjoins her listeners to "kiss your hands; love your heart."
BELOVED is such a side-ranging story that it's bound to feel slightly disjointed at times. The flashback to Sethe's escape from Sweet Home feels particularly drawn out, slowing down a nearly three-hour film. It's impressive, however, that three different screenwriters could create so cohesive an adaptation. Demme infuses BELOVED with the feverish intensity of a recurring nightmare, then leaves us with hope of awakening to a new day. There is emotion, yes, and dignity; there is also evil, and even horror. I can only think of one way to categorize a film like BELOVED: it may be the most uplifting horror film you'll ever see.
On the Renshaw scale of 0 to 10 immortal beloveds: 9.

Quick Rendezvous
Welcome to the QuickRendezvous appointment reservation system (under development).
This has been designed to allow management of huge queues where people need quick appointments as soon as possible that last a relatively short time. Appointments are set up first-come-first-served.
Possible uses:
- Booking Covid-19 testing appointments at a particular testing site (it is particularly suited for pop-up sites, so there need not be any physical lineups).
- Booking consultations with a teacher or professor (office hours)
- Booking vaccinations
- Booking appointments at recreational, cultural or commercial facilities, where the number of people present at a time must be controlled
If you have a queue link, you can request an appointment by providing your name, email and phone number. Please do not click on a link to use a queue unless you trust the source of the link, since you don't want to give your information to an untrusted source. In other words only follow links to queues from known websites.
The following link will take you to a practice queue where you can book pretend appointments and learn how the system works.
Try the practice queue.
Anyone can click below to create a queue and send or post the link. The queue manager will be provided with a secret link to set up available appointments and view the people who have booked.
Create a queue
Special features:
- Appointments can be set for any number of days in the future, but past ones disappear.
- Appointments can be automatically generated for the same time period each day, or different time periods on different days.
- New appointments can be added by the queue manager (e.g. if extra capacity becomes available).
- People always get the first available appointment by default, but can request to try to switch it to an earlier or later one. For example, an earlier appointment might become available due to a cancellation.
- This is designed for very fast response time.
- If there are no appointments, the system will allow requestors to try again later.
- Appointments can be generated gradually over time, preventing a rush (as would be the case if all tickets were released at the same time)
- The person managing a queue can allow multiple appointments at the same time if they so choose (e.g. for a recreational facility).
- The number of available appointments at different periods of time in the future is visible to users.
- The queue manager can embed their own logo and text in their page.
Future extensions planned:
- Verification of email address or phone number before an appointment can be booked (not free).
- Ability for the queue manager to specify the type of information to be gathered when a person requests an appointment.
- Making the site more pretty (without compromising its speed).
