The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data. Cassandra's support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages.
Cassandra is in use at Constant Contact, CERN, Comcast, eBay, GitHub, GoDaddy, Hulu, Instagram, Intuit, Netflix, Reddit, The Weather Channel, and over 1500 more companies that have large, active data sets.
Data is automatically replicated to multiple nodes for fault-tolerance. Replication across multiple data centers is supported. Failed nodes can be replaced with no downtime.
Cassandra consistently outperforms popular NoSQL alternatives in benchmarks and real applications, primarily because of fundamental architectural choices.
There are no single points of failure. There are no network bottlenecks. Every node in the cluster is identical.
Some of the largest production deployments include Apple's, with over 75,000 nodes storing over 10 PB of data, Netflix (2,500 nodes, 420 TB, over 1 trillion requests per day), Chinese search engine Easou (270 nodes, 300 TB, over 800 million requests per day), and eBay (over 100 nodes, 250 TB).
Cassandra is suitable for applications that can't afford to lose data, even when an entire data center goes down.
Choose between synchronous or asynchronous replication for each update. Highly available asynchronous operations are optimized with features like Hinted Handoff and Read Repair.
Read and write throughput both increase linearly as new machines are added, with no downtime or interruption to applications.
Cassandra support contracts and services are available from third parties.

"The Blair Witch Project" Review by Fontaine Lien WARNING: THIS REVIEW CONTAINS CRUCIAL PLOT INFO
The Blair Witch Project was overhyped.
And like most overhyped films, it was a major disappointment for me. It was praised as the scariest movie to be made since "The Shining" or "Halloween" or whatever, yadda yadda yadda, but in the end it was just a justifiably glorified experiment in independent film making. Creative? Yes. Well-acted? Yes. Laudable? That too. But scary? No. Not in the way it promised to be. It might be more appropriate for viewing at a quiet, private gathering in your home, rather than with a bunch of rowdy movie- goers who are just waiting to be scared.
I have to admit, the first five minutes really hooked me, because this was the first time we've actually seen movie actors look really crappy (i.e., realistic) on screen. No, I'm joking, but the point is we don't usually see character exposition like this, from the third person narrative to the first person, from hand-held video camera (documentary of the film makers themselves) to the actual black-and-white documentary of "The Blair Witch." It was like watching a family video on screen, it was an unprecedented blurring of the line between reality and fiction. Even the taglines for the film were cagey: they left people wondering whether this film that they were going to see was a real documentary, a fake one, a film containing documentary footage, or a documentary containing film footage. Yes, you would be as confused as I were, unless you're one of those people who read up everything you could on this film and was prepared, sort of. Not even "The Real World" or "Cops" achieved this kind of reality, which makes it all the more amazing because "Blair" is actually fictitious. I must marvel at the lengths the film makers had to have gone though to accomplish this feat . . . but did we *really* need to see an hour and a half of it before getting to the point? We knew these people were going to die, we knew that this time, the good guys weren't going to survive. The suspense just didn't work anymore when everyone was waiting to see how these characters would die.
"Blair" tried to make the supposed witch scary by having her described by commonfolk, by I think this was the witch's undoing. These people were too matter-of-fact; they spoke of the legends as if they were like any other small town stories. A hairy old woman with a shawl? Whatever. And why did kill? That was never explained either. The pile of rocks, the man-shaped twigs, the goo on Josh's "stuff." None of these were explained. If there were any scary images being conjured up in my head, they were pretty much diffused by the frequent switches between daylight and night time and the non-stop bickering between the characters, yeah, it's hilarious, and definitely much better than seeing people screaming their heads off and spouting off stupid lines, but it ruins the mood. The passionate will cry that we are all spoiled by special effects, that we need artificiality and contrivance to scare us. At this point I'm afraid that I must concede their statements to be at least partially true. Who wants reality when we can experience it first-hand?
It's a pity, really. If only the rest of the film were more like the last five or ten minutes: the desperate, haunting, and truly unnerving end to our three (or the two left) intrepid documentators. To me, that was the film's saving grace. If not for the ending (which gave me major chills when later that night I had to be alone in a big house: I kept imagining shadowy figures facing the corners of the walls), I would've walked off with a far worse impression of "Blair." I'm fond of it, and I admire it, but I wish it had lived up to expectations. The truth is I now see this film as an aborted genius, a glimpse at what might have been a true milestone in the horror genre.

KindredTails
A project towards child security. So that our children could be protected and explore.
Child protection is the safeguarding of children from violence, exploitation, abuse, and neglect. Article 19 of the UN Convention on the Rights of the Child provides for the protection of children in and out of the home
The Components used are
We are addressing a wide range of problems being faced by the society due to lack of awareness and sense of responsibility. In the 21st century, with the rise in statistical data for working parents, the most common option opted by them are daycare centers. When parents drop their children off at daycare, they expect that their kids will be safe. This is only possible with the proper security measures in place, such as security cameras, access control and visitor protocol. Security breaches can accidentally allow unauthorized people inside the facility, putting children at risk of kidnapping or injury. A few of them are listed below and our product helps in reducing them.
According to the data provided by the government, everyday 109 children are abused on daily basis (REPORTED CASES). Our product helps in identifying the voice patterns and send signal to parent if any hate speech, negative or suspicious comments are made by the speaker.
The count of people victim to human trafficking yearly is 6k (5264 in 2018) and are the cases that are reported by their kin. Our product uses geolocation to gain access to the user’s location and if the location is detected outside of safe area provided by their parents, an alert is sent to the customer showing the current location and thereby seeking officials help.
Children are allergic to certain food and may be exposed to them by carelessness of the daycare officials. Our product is integrated with OVA2640 camera equipped with image recognition to identify if the food kept in front of them is healthy for them or not, as listed by their parents.
With the rise in us of air conditioners and air pollution children are subjected to cold temperatures and bad air. Our product will be equipped with IR sensors for temperature measurement and MQ135 to keep the quality of air in check.


Add an event listener that fires when a user clicks a button:
The addEventListener() method attaches an event handler to the specified element.
The addEventListener() method attaches an event handler to an element without overwriting existing event handlers.
You can add many event handlers to one element.
You can add many event handlers of the same type to one element, i.e two "click" events.
You can add event listeners to any DOM object not only HTML elements. i.e the window object.
The addEventListener() method makes it easier to control how the event reacts to bubbling.
When using the addEventListener() method, the JavaScript is separated from the HTML markup, for better readability and allows you to add event listeners even when you do not control the HTML markup.
You can easily remove an event listener by using the removeEventListener() method.
The first parameter is the type of the event (like "click" or "mousedown").
The second parameter is the function we want to call when the event occurs.
The third parameter is a boolean value specifying whether to use event bubbling or event capturing. This parameter is optional.
| Note that you don't use the "on" prefix for the event; use "click" instead of "onclick". |
Alert "Hello World!" when the user clicks on an element:
You can also refer to an external "named" function:
Alert "Hello World!" when the user clicks on an element:
The addEventListener() method allows you to add many events to the same element, without overwriting existing events:
You can add events of different types to the same element:
The addEventListener() method allows you to add event listeners on any HTML DOM object such as HTML elements, the HTML document, the window object, or other objects that supports events, like the xmlHttpRequest object.
Add an event listener that fires when a user resizes the window:
When passing parameter values, use an "anonymous function" that calls the specified function with the parameters:
There are two ways of event propagation in the HTML DOM, bubbling and capturing.
Event propagation is a way of defining the element order when an event occurs. If you have a <p> element inside a <div> element, and the user clicks on the <p> element, which element's "click" event should be handled first?
In bubbling the inner most element's event is handled first and then the outer: the <p> element's click event is handled first, then the <div> element's click event.
In capturing the outer most element's event is handled first and then the inner: the <div> element's click event will be handled first, then the <p> element's click event.
With the addEventListener() method you can specify the propagation type by using the "useCapture" parameter:
The default value is false, which will use the bubbling propagation, when the value is set to true, the event uses the capturing propagation.
The removeEventListener() method removes event handlers that have been attached with the addEventListener() method:
The numbers in the table specifies the first browser version that fully supports these methods.
| Method | |||||
|---|---|---|---|---|---|
| addEventListener() | 1.0 | 9.0 | 1.0 | 1.0 | 7.0 |
| removeEventListener() | 1.0 | 9.0 | 1.0 | 1.0 | 7.0 |
Note: The addEventListener() and removeEventListener() methods are not supported in IE 8 and earlier versions and Opera 7.0 and earlier versions. However, for these specific browser versions, you can use the attachEvent() method to attach an event handlers to the element, and the detachEvent() method to remove it:
Cross-browser solution:


Interface IReadOnlyArea
Read-only interface for an arbitrary 2D area.
Inherited Members
Namespace: SadRogue.Primitives
Assembly: TheSadRogue.Primitives.dll
Syntax
public interface IReadOnlyArea : IMatchable<IReadOnlyArea>, IEnumerable<Point>, IEnumerable
Properties
Bounds
Smallest possible rectangle that encompasses every position in the area.
Declaration
Rectangle Bounds { get; }
Property Value
| Type | Description |
|---|---|
| Rectangle |
Count
Number of (unique) positions in the current area.
Declaration
int Count { get; }
Property Value
| Type | Description |
|---|---|
| Int32 |
Item[Int32]
Returns positions from the area in the same fashion you would via a list.
Declaration
Point this[int index] { get; }
Parameters
| Type | Name | Description |
|---|---|---|
| Int32 | index | Index of list to retrieve. |
Property Value
| Type | Description |
|---|---|
| Point |
UseIndexEnumeration
Whether or not it is more efficient for this implementation to use enumeration by index, rather than generic IEnumerable, when iterating over positions using ReadOnlyAreaPositionsEnumerator.
Declaration
virtual bool UseIndexEnumeration { get; }
Property Value
| Type | Description |
|---|---|
| Boolean |
Remarks
Set this to true if your indexer implementation scales well (constant time), and is relatively fast. Implementations with more complex indexers should set this to false.
The default interface implementation returns false, in order to preserve backwards compatibility with previous versions.
If you set this to false, your IEnumerable.GetEnumerator() implementations must NOT call return a ReadOnlyAreaPositionsEnumerator, as this will create an infinite loop.
Methods
Contains(IReadOnlyArea)
Returns whether or not the given area is completely contained within the current one.
Declaration
bool Contains(IReadOnlyArea area)
Parameters
| Type | Name | Description |
|---|---|---|
| IReadOnlyArea | area | Area to check. |
Returns
| Type | Description |
|---|---|
| Boolean | True if the given area is completely contained within the current one, false otherwise. |
Contains(Point)
Determines whether or not the given position is considered within the area or not.
Declaration
bool Contains(Point position)
Parameters
| Type | Name | Description |
|---|---|---|
| Point | position | The position to check. |
Returns
| Type | Description |
|---|---|
| Boolean | True if the specified position is within the area, false otherwise. |
Contains(Int32, Int32)
Determines whether or not the given position is considered within the area or not.
Declaration
bool Contains(int positionX, int positionY)
Parameters
| Type | Name | Description |
|---|---|---|
| Int32 | positionX | X-value of the position to check. |
| Int32 | positionY | X-value of the position to check. |
Returns
| Type | Description |
|---|---|
| Boolean | True if the specified position is within the area, false otherwise. |
GetEnumerator()
Returns an enumerator which can be used to iterate over the positions in this area in the most efficient manner possible via a generic interface.
Declaration
virtual ReadOnlyAreaPositionsEnumerator GetEnumerator()
Returns
| Type | Description |
|---|---|
| ReadOnlyAreaPositionsEnumerator | A custom enumerator that iterates over the positions in the area in the most efficient manner possible via a generic interface. |
Remarks
The enumerator returned will use the area's indexer to iterate over the positions (like you might a list), if the area's UseIndexEnumeration is true. Otherwise, it uses the typical IEnumerator implementation for that area.
This may be significantly faster than the typical IEnumerable/IEnumerator usage for implementations which have UseIndexEnumeration set to true; however it won't have much benefit otherwise.
If you have a value of a concrete type rather than an interface, and the GetEnumerator implementation for that given type is particularly fast or a non-boxed type (like Area, you will probably get faster performance out of that than by using this; however this will provide better performance if you are working with an interface and thus don't know the type of area. Use cases for this function are generally for iteration via IReadOnlyArea.
Intersects(IReadOnlyArea)
Returns whether or not the given map area intersects the current one. If you intend to determine/use the exact intersection based on this return value, it is best to instead call GetIntersection(IReadOnlyArea, IReadOnlyArea, IEqualityComparer<Point>), and check the number of positions in the result (0 if no intersection).
Declaration
bool Intersects(IReadOnlyArea area)
Parameters
| Type | Name | Description |
|---|---|---|
| IReadOnlyArea | area | The area to check. |
Returns
| Type | Description |
|---|---|
| Boolean | True if the given area intersects the current one, false otherwise. |

When creating a GUI application, you need to specify a
top-level widget
, which is usuallyQDialog
,QWidget
, orQMainWindow
. If you create an application based on theDialog template
, the top-level widget or the first class that you inherit isQDialog
. Similarly, if the application is based on theMain Window template
, the top-level widget will beQMainWindow
, and if you use theWidget template
for your application, the top-level widget will beQWidget
. The widgets that you use for the user interface are then treated as child widgets of the classes.The
main component
used for creating a user interface iswidgets
.Button
,menus
, andscrollbars
are examples of widgets and are not only used for receiving user input but also for displaying data and status information.Widgets
can benested
inside another in a parent-child relationship. A widget that hasno parent widget
is called awindow
. The class for widgets,QWidget
, provides methods to render them on screen, receive user input, and handle different events.All UI elements that Qt provides are subclasses of QWidget
. Qt Designer displays a list of widgets in a Widget Box displayed on the left side.
Widget Box
- Widget Box 用于分类显示 widget 的列表, 相似功能的 widget 放入一个分类中

基本控件
Displaying Text
To display non-editable text or an image, Label widgets are used; a Label is an instance of the
QLabel
class. A Label widget is a very popular widget for displaying messages or information to the user.
| Methods | Usage |
|---|---|
| setText() | Assigns text to the Label widget |
| setPixmap() | Assigns a pixmap, an instance of the QPixmapclass, to the Label widget |
| setNum() | Assigns an integer or double value to the Label widget |
| clear() | Clears text from the Label widget |
Entering Single-Line Data
To allow the user to enter or edit single-line data, you use the Line Edit widget, which is an instance of
QLineEdit
. The widgetsupports
simple editing mechanisms such asundo
,redo
,cut
, andpaste
.
| Methods | Usage |
|---|---|
| setEchoMode() | Used to set the echo mode of the Line Edit widget to determine how the contents of the Line Edit widget are displayed. The available options are these: Normal: Default mode. Displays characters as they are entered. NoEcho: Doesn’t display anything. Password: Displays asterisks as the user enters data. PasswordEchoOnEdit: Displays characters when editing; otherwise, asterisks are displayed. |
| maxLength() | Used to specify the maximum length of text that user can enter. For multiline editing, you use QTextEdit |
| setText() | Assigns text to the Line Edit widget |
| text() | Fetches the text entered in the Line Edit widget |
| clear() | Clears the contents of the Line Edit widget |
| setReadOnly() | Passes the Boolean value true to this method to make the Line Edit widget read-only. The user cannot edit the contents of the Line Edit widget but can copy it. The cursor will become invisible in read-only mode |
| isReadOnly() | Returns true if the Line Edit widget is in read-only mode |
| setEnabled() | The Line Edit widget will be blurred, indicating that it is disabled. You cannot edit content in a disabled Line Edit widget, but you can assign text via the setText() method |
| setFocus() | Used to set the cursor on the specified Line Edit widget |
- 相关信号(signal)
| Signals | Usage |
|---|---|
| textChanged() | The signal is emitted when text in the Line Edit widget is changed |
| returnPressed() | The signal is emitted when Return or Enter is pressed |
| editingFinished() | The signal is emitted when focus is lost on the Line Edit widget, confirming the editing task is over on it |
Displaying Buttons
To display pushbuttons (usually command buttons) in an application, you need to create an instance of the
QPushButton
class. When assigning text to buttons, you can createshortcut
keys by preceding any character in the text with anampersand
.
| Methods | Usage |
|---|---|
| setText() | Used to assign the text to the pushbutton |
| setIcon() | Used to assign icon to the pushbutton |
Event Handling in PyQt
In PyQt, the
event-handling mechanism
is also known assignals and slots
. Every widget emits signals when its state changes. Whenever a signal is emitted, it is simply thrown. To perform a task in response to a signal, the signal has to be connected to a slot. A slot refers to the method containing the code that you want to be executed on occurrence of a signal. Most widgets have predefined slots, you don’t have to write code for connecting a predefined signal to a predefined slot. To respond to the signals emitted, you identify theQObject
and the signal it emits and invoke the associated method. You can use Qt Designer for connecting signals with built-in slots.

This is the first in my series of posts on optimizing Erlang. I plan to tackle optimizing Mnesia, profiling and scalability.
You need to use arrays of up to 10,000 elements. Erlang offers you tuples as well as fixed-size and extensible pseudo-arrays. What is the fastest option?
Let us start the death match by pitting arrays against tuples in a death match. Trees were an option before the array module became available, so lets throw in trees just for laughs.
I’m running Mac OSX Leopard 10.5.4 on a Mac Pro 2×2.8Ghz Quad-Core Intel Xeon with 14Gb 800Mhz DDR2 FB-DIMM.
Erlang (BEAM) emulator version 5.6.3 [source] [64-bit] [smp:8] [async-threads:0] [kernel-poll:false]
27> arr:test().
Fixed-size array: get: 2921µs, set: 5902µs
Extensible array: get: 3336µs, set: 8144µs
Tuple: get: 632µs, set: 107467µs
Tree: get: 4321µs, set: 45256µs
ok
30> arr:test(100000).
Fixed-size array: get: 35314µs, set: 74653µs
Extensible array: get: 35349µs, set: 74059µs
Tuple: get: 6411µs, set: 24304490µs
Tree: get: 53681µs, set: 632795µs
ok
Note that timer:tc returns time in microseconds. I ran each test 3 times and the results above are from the third iteration.
Trees in Erlang (gb_trees) are built on top of regular tuples and so is the array module. The array module is much more efficient about using tuples than a regular tree, though, and this is the reason why it’s so much faster.
The tuple test pre-allocates a tuple of 10k or 100k elements. There’s no destructive assignment in Erlang and so the same large tuple needs to be allocated and discarded on every set operation. It’s very inefficient to allocate and discard a large tuple on every set operation, thus naive tuple set is very slow.
The array module uses an efficient tree-like internal representation:
%% A tree is either a leaf, with LEAFSIZE elements (the "base"), an
%% internal node with LEAFSIZE+1 elements, or an unexpanded tree,
%% represented by a single integer: the number of elements that may be
%% stored in the tree when it is expanded. The last element of an
%% internal node caches the number of elements that may be stored in
%% each of its subtrees.
%%
%% Note that to update an entry in a tree of height h = log[b] n, the
%% total number of written words is (b+1)+(h-1)*(b+2), since tuples use
%% a header word on the heap. 4 is the optimal base for minimizing the
%% number of words written, but causes higher trees, which takes time.
%% The best compromise between speed and memory usage seems to lie
%% around 8-10. Measurements indicate that the optimum base for speed is
%% 24 - above that, it gets slower again due to the high memory usage.
%% Base 10 is a good choice, giving 2/3 of the possible speedup from
%% base 4, but only using 1/3 more memory. (Base 24 uses 65% more memory
%% per write than base 10, but the speedup is only 21%.)
It’s far more efficient to allocate small tuples on every set and this is why the array module wins hands down.
Use this code to replicate my results on your hardware.

Class Creation (pattern)
// Class is created altirnatively for constructor. class Animal { // Constructor i class is obligatory. constructtor(name, species) { this.name = name; this.species = species; this.eat = function () { console.log(this.name + ' mniam mniam :)'); } } }
Class
class Animal { constructor(name, species) { this.name = name; this.species = species; this.eat = function() { console.log(this.name + ' mniam mniam :)'); } } }
Constructor
function Animal(name, specis) { this.name = name; this.species = species; this.eat = function() { console.log(this.name + ' mniam mniam :)'); } }
Class creation - pattern cont.
class Animal { constructor(name, species) { this.name = name; this.species = species; } // For the prototype of the class such a function is added - and we do not need to use the method function b4 the method name: eat() { console.log(this.name + ' auuu (jakie to dobre)'); } }
Class
class Animal { constructor(name, species) { this.name = name; this.species = species; } // here declaring prototype inside the class: eat() { console.log('jedz ' + this.name); } };
Take a look that the content of class is a set of methodes:
1. constructor is a method - basic method
2. eat() is a prototype method - and can be many of them.
Constructor with prototype
function Animal (name, species) { this.name = name; this.species = species; } // and here separately/outside of constructor we are creating prototype: Animal.prototype.eat = function() { console.log('jedz ' + this.name); };
Crating of class instance
const dog = new Animal('Reksio', 'Kundel bury'); // Syntax is the same as with the constructor and the same working mechanisms typeof Animal //'Function' - the class is a function
this is a mechanism in JavaScript which can be unpredictible for us ;)
Thanks to this our code is more uninversal.

Take the keys which you have in your hand and toss. and many more...
btn.addEventListener('click', function() { this.classList.toggle('on'); }) // this is refered to the button /object where the function is executed - btn. // Take a look that the same function can be executed on many elements, is universal, because connection with that object acts in a moment of calling back the function not in the moment of creating that function. - em It is needed to be remembered.
btn.addEventListener('click', () => { this.classList.toggle('on'); }) // this is refered to the global object because arrow function does not creates the own connection this just takes it over the higheer scope (so if addEventListener in in the global scope than from that global scope).
this - another example
const car = { name: 'Polonez', year: 1999, age() { console.log(`Wiek samochodu, to ${2020 - this.year} lat.) } } // calling back the age: car.age() // 'Wiek samochodu, to 21 lat.'
this will be reffered to the car object but remember that (connection, object definition) will appear in a moment of executing the method so in here cr.age()


Key functionality
The nanodiffraction toolbox should provide the following functionality:
- Sequential file reading and processing
- Data masking
- Data selection
- Standalone functions for single-frame data analysis
- Data regridding
- Angular and azimuthal integration (with or without data selection)
- Standard visualizations with proper choice of color and scaling
- Principal component analysis
- Rotational symmetry detection
- Background modeling
Hence, data should be properly reduced to a finite set of meaningful structural parameters. Some functionality is either built from scratch, or, built upon other work. In order to avoid duplication of code, other software packages are used, such as pyFAI for fast azimuthal integration. In other cases, functions have been written, based on other publications, that are listed below.
To increase usage, important functions are re-written in the C programming language to be more easily linked to other toolboxes or software packages.
Syntax and proper usage
Detailed documentation is provided here and within the Matlab package by using the doc or help function of Matlab.

I am a Responsive Designer & Developer who loves to help people build and grow their business on the backend
in a creavative coding way, but I am also a wife to an amazing man and a mom to
two beautiful girls. I found coding later in life and it has shown me that it's never to later
to learn something new.
I was born in El Paso, Tx but moved to the 24hr town of Las Vegas, NV at the age
of 2. I would consider myself a native, but the "Born and Raised" would like to
think other wise.
I love anything that has to do with being creative. Art, fashion, music all of those things drive
me to express my creativity. And now I have coding another outlet to express my creativity.
I also, love yoga, snowboarding, hiking, going to the beach and spending all my free time with my family.
They are the driving force in my life. I live for them.
