configuration definitions
| #define DESTRUCTOR_CLOSES_FILE 0 |
Set DESTRUCTOR_CLOSES_FILE nonzero to close a file in its destructor.
Causes use of lots of heap in ARM.
| #define ENABLE_EXTENDED_TRANSFER_CLASS 0 |
If the symbol ENABLE_EXTENDED_TRANSFER_CLASS is nonzero, the class SdFatEX will be defined. If the symbol ENABLE_SOFTWARE_SPI_CLASS is also nonzero, the class SdFatSoftSpiEX will be defined.
These classes used extended multi-block SD I/O for better performance. the SPI bus may not be shared with other devices in this mode.
| #define ENABLE_SDIO_CLASS 0 |
Enable SDIO driver if available.
| #define ENABLE_SOFTWARE_SPI_CLASS 0 |
If the symbol ENABLE_SOFTWARE_SPI_CLASS is nonzero, the class SdFatSoftSpi will be defined. If ENABLE_EXTENDED_TRANSFER_CLASS is also nonzero, the class SdFatSoftSpiEX will be defined.
| #define ENDL_CALLS_FLUSH 0 |
Call flush for endl if ENDL_CALLS_FLUSH is nonzero
The standard for iostreams is to call flush. This is very costly for SdFat. Each call to flush causes 2048 bytes of I/O to the SD.
SdFat has a single 512 byte buffer for SD I/O so it must write the current data block to the SD, read the directory block from the SD, update the directory entry, write the directory block to the SD and read the data block back into the buffer.
The SD flash memory controller is not designed for this many rewrites so performance may be reduced by more than a factor of 100.
If ENDL_CALLS_FLUSH is zero, you must call flush and/or close to force all data to be written to the SD.
| #define FAT12_SUPPORT 0 |
Set FAT12_SUPPORT nonzero to enable use if FAT12 volumes. FAT12 has not been well tested and requires additional flash.
| #define IMPLEMENT_SPI_PORT_SELECTION 0 |
Check if API to select HW SPI port is needed.
| #define MAINTAIN_FREE_CLUSTER_COUNT 0 |
Set MAINTAIN_FREE_CLUSTER_COUNT nonzero to keep the count of free clusters updated. This will increase the speed of the freeClusterCount() call after the first call. Extra flash will be required.
| #define SD_HAS_CUSTOM_SPI 0 |
Determine the default SPI configuration.
| #define USE_LONG_FILE_NAMES 1 |
Set USE_LONG_FILE_NAMES nonzero to use long file names (LFN). Long File Name are limited to a maximum length of 255 characters.
This implementation allows 7-bit characters in the range 0X20 to 0X7E except the following characters are not allowed:
< (less than)
(greater than)
: (colon) " (double quote) / (forward slash) \ (backslash) | (vertical bar or pipe) ? (question mark)
| #define USE_MULTI_BLOCK_IO 1 |
Set USE_MULTI_BLOCK_IO nonzero to use multi-block SD read/write.
Don't use mult-block read/write on small AVR boards.
| #define USE_SD_CRC 0 |
To enable SD card CRC checking set USE_SD_CRC nonzero.
Set USE_SD_CRC to 1 to use a smaller CRC-CCITT function. This function is slower for AVR but may be fast for ARM and other processors.
Set USE_SD_CRC to 2 to used a larger table driven CRC-CCITT function. This function is faster for AVR but may be slower for ARM and other processors.
| #define USE_SEPARATE_FAT_CACHE 0 |
Set USE_SEPARATE_FAT_CACHE nonzero to use a second 512 byte cache for FAT table entries. This improves performance for large writes that are not a multiple of 512 bytes.
| #define USE_STANDARD_SPI_LIBRARY 0 |
| #define WDT_YIELD_TIME_MICROS 0 |
Handle Watchdog Timer for WiFi modules.
Yield will be called before accessing the SPI bus if it has been more than WDT_YIELD_TIME_MICROS microseconds since the last yield call by SdFat.

Data Process¶
Data process is essential in EEG signal analysis. First, original EEG signal may contain missing values and noise, which may disturb or hidden the real information. Also, a lot of research works have shown that the spectrum properties of EEG on certain frequency bands are very important to uncover useful information which cannot be directly quantified by original temporal signal. In addition, the number of samples are relatively small for EEG signal, which may not fully release the power of machine learning. Data augmentation through segmentation and sampling are two major ways to increase sample size in EEG analysis.
So we designed the data process module to provide solutions to the requirements mentioned above. The data process module contains 5 functions:
process.check(process_check)
process.smooth(process_smooth)
process.band(process_band)
process.segment(process_segment)
process.sampling(process_sampling)
process.check¶
Check whether the input signal contains NaN, print relevant information
- input:
array: numpy array. The temporal signal with 1d or with multiple dimensions
- return:
None or dict. Dict stores indicator of Nan/Abnormal values. If there is no NaN in signal, return None, else return the index where NaN occurs.
process.smooth¶
Apply the Savitzky-Golay fiklter to smooth signals. We support both 1d array input and DEEG standard input (p,m,e). For the later format, we calculate DE on “e” dimension and return a (p,m) numpy array.
- input:
signal: numpy array or list.window_size: int. the length of the filter window (i.e., the number of coefficients).
window_size: int. the length of the filter window (i.e., the number of coefficients). window_length must be a positive odd integer. default is 5.
polyorder: int. the order of the polynomial used to fit the samples. polyorder must be less than window_length. default is 2.
- return:
y: ndarray. same shape as x. The filtered data.
process.band¶
Filter temporal signal by all the 5 filters commonly used in EEG analysis: delta, theta, alpha, beta, gamma.
- input:
signal: numpy array. The input temporal signal. 1d or with multiple dimensions
- return:
ts_dict: dictionary. Keys are filter name and values are filtered signal in temporal domain.
process.segment¶
Generate the signal segments to augment sample size.
- input:
array: numpy array. The input temporal signal. 1d or with multiple dimensions
length: int. The length of segments. Default is 10, which means each signal segment contains 10 data points.
overlap: int. The overlap length between neighboring segments. Default is 1.
- return:
segmented_array: numpy array with shape (p,m,s,e) or (s,e), depending on the input. s is the number of segments.
process.sampling¶
Down-sample the input signal with certain interval.
- input:
array: numpy array. The input temporal signal. 1d or with multiple dimensions
interval: int. The interval to sample EEG signal. Default is 1, which means NO down-sampling is applied
offset: int. Sampling starts from “offset-th” data point
- return:
sampled_array: numpy array. Down-sampled signal

Dear Friend, I am Bill Franklyn,a Financial Consultant Account portfolio manager based and working in London UK, working in one of the leading finance houses and I happen to have managed a particular account for a Resident Foreigner,here in the United Kingdom,who died Interstate, leaving in our care a sizeable amount in a domiciliary United States Dollars Investment Account. For some reasons this client does not have an easily identifiable next of Kin and I have made several enquiries to locate any of my clients relatives; immediate and extended, this has proved unsuccessful, hence I am contacting you "based on the fact that you have similar names". I need your assistance in securing the money and property left behind by my client before they get confiscated or declared unserviceable by the Finance House here in the United Kingdom. The Finance House has already issued a Government Mandatory formality notice to provide the Next of Kin or have the account confiscated and this should expire within a month. Since I have been unsuccessful in locating any of his relatives for over two years and convinced that no one is coming up and having satisfied the mandatory legal requirement of Beneficiary next of kin Notification, I now seek a Reliable and Trustworthy person,with your consent and perfect understanding, to present you as the next of kin of the deceased so that the proceeds of this account initially valued at Twenty One Million, Three Hundred And Twenty Thousand United States Dollars,($21,320,000) interest not inclusive, can be paid into an account to be provided by you(preferably) outside the United Kingdom Financial Institutions or its Isles), as the perceived Next Of Kin Legally and Otherwise. All I require is your honest cooperation and confidence in me; which I know would not come easy. I guarantee that this will be executed under a legitimate background that will protect you from any breach of the law. I would advise that you give this positive consideration and get back to me soon. I'll be flexible and considerate in the percentage share that will be given to you for your assistance. Upon receipt of your response we will exchange contact information so that we can reach each other for further discussions. Regards, Bill Franklyn


Beginning with version nb184, App Inventor has included the capability to cut, copy, and paste parts of your app design. This document explains this functionality.
Manipulating Components
Your app design is made up of one or more components in a tree structure that starts at the Screen. You can add components by dragging them in from the Palette panel to the left of the designer. You can customize components by changing their properties in the Properties panel to the right of the designer.
Selecting Components
You select components by clicking on them. Starting with release nb182, you can select multiple components by holding a platform specific key (Ctrl on Windows/Linux, Command on macOS) and clicking on additional components. This feature is sometimes referred to in App Inventor as multiselect. When you select multiple components, the properties panel will update to only show common properties among the selected components. Changing a property in this mode will change it for all of the selected components.
Copying Components
Once you have selected one or more elements, use the standard keyboard shortcut for your platform to copy them (Ctrl+C on Windows/Linux, ⌘C on macOS). This places the contents of the selection onto your system’s clipboard.
You can also use the Cut shortcut (Ctrl+X on Windows/Linux, ⌘X on macOS) to copy elements to the clipboard and immediately delete them, so that they can be pasted elsewhere.
Pasting Components
Once you have copied components to the clipboard, you can press the paste shortcut key (Ctrl+V on Windows/Linux, ⌘V on macOS) to paste them. When copying and pasting components, the default behavior is to copy both the design as well as the behavior (i.e., the blocks). If you would prefer to only paste the component without copying its behavior, hold the shift key while pressing the paste key combination. App Inventor will skip pasting the blocks if the shift key is held.
When pasting, App Inventor will rename the pasted components if there is a collision with existing components in the project. It does this by computing a fresh name for each colliding name. The renaming algorithm works by either adding a numeric suffix to the name, or by incrementing the numeric suffix of the name until the collision is resolved. For example, if you copy a component named ResetButton
, the first copy will be called ResetButton1
, the second will be called ResetButton2
, and so forth. These new names are also subsituted into the copied blocks code, if any.
Manipulating Blocks
The blocks editor is where you provide the behavior for your app. Like the designer, it supports copying and pasting blocks. You can also use the backpack to transfer blocks between projects, or download blocks as images that you can share with others.
Copying Blocks
To copy a block, first select the block. You can copy the block by either pressing the copy shortcut for your platform (Ctrl+C for Windows/Linux, ⌘C for macOS). The copy action is also available on the context menu by right clicking (Ctrl+clicking on macOS) the block.
Paste Blocks
To paste a block, press the paste shortcut for your platofmr (Ctrl+V for Windows/Linux, ⌘V on macOS). The paste action is also available on the context menu by right clicking (Ctrl+clicking on macOS) the workspace.
Copying Screens
App Inventor allows you to copy and paste the content of a screen, effectively allowing you to copy screens.
To copy a screen, select the screen either by clicking its background or selecting it in the structure tree. Press the copy shortcut key to copy it. Next, create a new screen. Press the paste shortcut key in this new screen to paste the contents copied from the previous screen.
Sharing Designs
Because the copy functionality puts the content of your selection onto the clipboard, it is possible to share the content in a text form although the format is somewhat complex. For example, you can copy a component and paste its textual representation into a text document or email. Someone can select the text, copy it, and then paste it into App Inventor to recreate the component’s representation. This can help you build a collection of design elements for your apps.

Italians Are Pissed Off at ‘I told you so’ Meme with Greta Thunberg in Flooded Venice
Greta Thunberg’s popularity has reached such levels that she remains in the spotlight even when she hasn’t done or said anything. This time it happened in Venice, Italy, which has recently been hit by severe flooding.
Italians are incensed at a meme featuring climate activist Greta Thunberg in flood-stricken Venice. The 16-year-old was photoshopped into a picture of flooded St. Mark's Square in Venice, where the climate activist stands waist-deep in water wearing a yellow coat with a challenging look on her face and a caption reading "I told you so".
Netizens were outraged when the meme created by Luca Fancellu was retweeted by popular channel Spinoza, with some social media users saying that this is not the time for jokes.
 The so-called Mose Project, designed to shield the city from flooding using large barriers, has been underway since 2003. It has cost Venetians billions of euros and has been marred by scandals and delays.
Despite the recent flooding having caused enormous damage worth hundreds of millions of euros and resulting in the deaths of two people it is not the worst in Italy’s history. A 1966 flood saw water levels rise to 1.94 metres, something that was mentioned by a few users, who also cautioned against stirring up hysteria about climate change.
Tweet: “Some would say same level as in 1966.
Well, "Acqua Alta" in Venice is a very common event.
Shame on you for trying to drive clima hysterics with it. pic.twitter.com/P6fHriImnv
Venice has recently been hit by its worst flooding in 50 years, with waters peaking at 1.87 metres. Pictures posted online show water swamping centuries-old buildings, including the iconic Saint Mark’s Basilica. Mayor Luigi Brugnaro said the city is “on its knees” and put the blame on climate change for the natural disaster.

Development Strategy¶
Roadmap¶
We are going to look out 12 months to establish a set of goals we want to work towards. When planning, we typically look at potential work from the perspective of the elements.
Qiskit Terra¶
In 2018 we worked on formalizing the backends and user flow in Qiskit Terra. The basic idea is as follows: the user designs a quantum circuit and then, through a set of transpiler passes, rewrites the circuit to run on different backends with different optimizations. We also introduced the concept of a provider, whose role is to supply backends for the user to run quantum circuits on. The provider API we have defined at version one supplies a set of schemas to verify that the provider and its backends are Terra-compatible.
In 2019, we have many extensions planned. These include:
- Add passes to the transpiler. The goal here is to be more efficient in circuit depth as well as adding passes that find approximate circuits and resource estimations.
- Introduce a circuit foundry and circuit API. This has the goal of making sure that a user can easily build complex circuits from operations. Some of these include adding controls and power to operations, and inserting unitary matrices directly.
- Provide an API for OpenPulse. Now that OpenPulse is defined, and the IBM Q provider can accept it, we plan to build out the pulse features. These will include a scheduler and tools for building experiments out of pulses. Also included will be tools for mapping between experiments with gates (QASM) to experiments with pulses.
Qiskit Aer¶
The first release of Qiskit Aer was made avaialble at the end of 2018. It included C++ implementations of QASM, statevector, and unitary simulators. These are the core to Qiskit Aer, and replace the simulators that existed in Terra. The QASM simulator includes a customizable general (Kraus) noise model, and all simulators are include CPU parallelization through the OpenMP library.
In 2019, Aer will be extended in many ways:
- Optimize simulators. We are going to start profiling the simulators and work on making them faster. This will include automatic settings for backend configuration and OpenMP parallelization configuration based on the input Qobj and available hardware.
- Develop additional simulator backends. We will include several approximate simulator backends that are more efficient for specific subclasses of circuits, such as the T-gate simulator, which works on Clifford and T gates (with low T-depth), and a stabilizer simulator, which works just on Clifford gates.
- Add noise approximation tools. We plan to add noise approximation tools to mapping general (Kraus) noise models to approximate noise model that may be implemented on an approximate backends (for example only mixed Clifford and reset errors in the noise model).
Qiskit Ignis¶
This year, we are going to release the first version of Qiskit Ignis. The goal of Ignis is to be a set of tools for characterization of errors, improving gates, and enhancing computation in the presence of noise. Examples of these tools include optimal control, dynamical decoupling, and error mitigation.
In 2019, Ignis will include tools for:
- quantum state/process tomography
- randomized benchmarking over different groups
- optimal control (e.g., pulse shaping)
- dynamical decoupling
- circuit randomization
- error mitigation (to improve results for quantum chemistry experiments)
Qiskit Aqua¶
Aqua is an open-source library of quantum algorithms and applications, introduced in June 2018. As a library of quantum algorithms, Aqua comes with a rich set of quantum algorithms of general applicability—such as VQE, QAOA, Grover's Search, Amplitude Estimation and Phase Estimation—and domain-specific algorithms-such as the Support Vector Machine (SVM) Quantum Kernel and Variational algorithms, suitable for supervised learning. In addition, Aqua includes algorithm-supporting components, such as optimizers, variational forms, oracles, Quantum Fourier Transforms, feature maps, multiclass classification extension algorithms, uncertainty problems, and random distributions. As a framework for quantum applications, Aqua provides support for Chemistry (released separately as the Qiskit Chemistry component), as well as Artificial Intelligence (AI), Optimization and Finance. Aqua is extensible across multiple domains, and has been designed and structured as a framework that allows researchers to contribute their own implementations of new algorithms and algorithm-supporting components.
Over the course of 2019, we are planning to enrich Aqua as follows:
- We will include several new quantum algorithms, such as Deutsch-Jozsa, Simon's, Bernstein-Vazirani, and Harrow, Hassidim, and Lloyd (HHL).
- We will improve the performance of quantum algorithms on top of both simulators and real hardware.
- We will provide better support for execution on real quantum hardware.
- We will increase the set of problems supported by the AI, Optimization and Finance applications of Aqua.
Summary¶
These are examples of just some of the work we will be focusing on in the next 12 months. We will continuously adapt the plan based on feedback. Please follow along and let us know what you think!
Versioning¶
The Qiskit project is made up of several elements each performing different functionality. Each is independently useful and can be used on their own, but for convenience we provide this repository and meta-package to provide a single entrypoint to install all the elements at once. This is to simplify the install process and provide a unified interface to end users. However, because each Qiskit element has it's own releases and versions some care is needed when dealing with versions between the different repositories. This document outlines the guidelines for dealing with versions and releases of both Qiskit elements and the meta-package.
For the rest of this guide the standard Semantic Versioning nomenclature will
be used of: Major.Minor.Patch
to refer to the different components of a
version number. For example, if the version number was 0.7.1
, then the major
version is 0
, the minor version 7
, and the patch version 1
.
Meta-package Version¶
The Qiskit meta-package version is an independent value that is determined by the releases of each of the elements being tracked. Each time we push a release to a tracked component (or add an element) the meta-package requirements, and version will need to be updated and a new release published. The timing should be coordinated with the release of elements to ensure that the meta-package releases track with element releases.
Adding New Elements¶
When a new Qiskit element is being added to the meta-package requirements, we need to increase the Minor version of the meta-package.
For example, if the meta-package is tracking 2 elements qiskit-aer
and
qiskit-terra
and it's version is 0.7.4
. Then we release a new element
qiskit-ignis
that we intend to also have included in the meta-package. When
we add the new element to the meta-package we increase the version to
0.8.0
.
Patch Version Increases¶
When any Qiskit element that is being already tracked by the meta-package releases a patch version to fix bugs in a release we need also bump the requirement in the setup.py and then increase the patch version of the meta-package.
For example, if the meta-package is tracking 3 elements qiskit-terra==0.8.1
,
qiskit-aer==0.2.1
, and qiskit-ignis==0.1.4
with the current version
0.9.6
. When qiskit-terra release a new patch version to fix a bug 0.8.2
the meta-package will also need to increase it's patch version and release,
becoming 0.9.7
.
Additionally, there are occasionally packaging or other bugs in the meta-package itself that need to be fixed by pushing new releases. When those are encountered we should increase the patch version to differentiate it from the broken release. Do not delete the broken or any old releases from pypi in any situation, instead just increase the patch version and upload a new release.
Minor Version Increases¶
Besides adding a new element to the meta-package the minor version of the meta-package should also be increased anytime a minor version is increased in a tracked element.
For example, if the meta-package is tracking 2 elements qiskit-terra==0.7.0
and qiskit-aer==0.1.1
and the current version is 0.7.5
. When the
qiskit-aer
element releases 0.2.0
then we need to increase the
meta-package version to be 0.8.0
to correspond to the new release.
Major Version Increases¶
The major version is different from the other version number components. Unlike
the other version number components, which are updated in lock step with each
tracked element, the major version is only increased when all tracked versions
are bumped (at least before 1.0.0
). Right now all the elements still have
a major version number component of 0
and until each tracked element in the
meta-repository is marked as stable by bumping the major version to be >=1
then the meta-package version should not increase the major version.
The behavior of the major version number component tracking after when all the elements are at >=1.0.0 has not been decided yet.
Qiskit Element Requirement Tracking¶
While not strictly related to the meta-package and Qiskit versioning how we track the element versions in the meta-package's requirements list is important. Each element listed in the setup.py should be pinned to a single version. This means that each version of Qiskit should only install a single version for each tracked element. For example, the requirements list at any given point should look something like:
requirements = [
"qiskit_terra==0.7.0",
"qiskit-aer==0.1.1",
]
This is to aid in debugging, but also make tracking the versions across multiple elements more transparent.
It is also worth pointing out that the order we install the elements is
critically important too. pip
does not have a real dependency solver which
means the installation order matters. So if there are overlapping requirements
versions between elements or dependencies between elements we need to ensure
that the order in the requirements list installs everything as expected. If the
order needs to be change for some install time incompatibility it should be
noted clearly.
Module Status¶
Qiskit is developing so fast that is it is hard to keep all different parts of the API supported for various versions. We do our best and we use the rule that for one minor version update, for example 0.6 to 0.7, we will keep the API working with a deprecated warning. Please don’t ignore these warnings. Sometimes there are cases in which this can’t be done and for these in the release history we will outline these in great details.
This being said as we work towards Qiskit 1.0 there are some modules that have become stable and the table below is our attempt to label them
Modules¶
| Name | status | Note |
|---|---|---|
| assembler | stable | completed in version 0.9 |
| circuit | unstable | |
| compiler | stable | completed in version 0.9 |
| converters | unstable | |
| dagcircuit | remove | will be part of circuits |
| extensions | remove | will be part of circuits |

| tools | unstable | various elements to be removed |
| transpiler | stable | completed in version 0.9 |
| validation | stable | completed in version 0.7 |
| visualization | stable | completed in version 0.9 |
Providers¶
There are three providers that come with the default installation of Qiskit
Basic Aer Provider¶
This provider simulates ideal quantum circuits and has three backends. As Aer becomes more stable and can work on any operating system this provider will be removed.
Aer Provider¶
This is a more advance simulator that is written in C++. It runs faster than Basic Aer and also allows you to add noise to your circuits. This allow you to explore what happens to your circuits for realistic models of the experiments and design experiments that might be more resilient to the noise in today’s quantum computers.
IBM Q Provider¶
This provider gives you access to real experiments. You will need an IBM Q Experience account to use it. It also has an online HPC simulator that can be used. It is a hosted version of the Aer Provider.
Community Extensions¶
Qiskit has been designed with modularity in mind. It is extensible in many different ways; on the page, we highlight the ways in which the Qiskit community has engaged with Qiskit and developed extensions and packages on top of it.
Providers¶
The Qiskit base provider is an entity that provides access to a group of different backends (for example, backends available through IBM Q). It interacts with those backends to do many things: find out which ones are available, retrieve an instance of a particular backend, get backend properties and configurations, and handling running and working with jobs.
Additional providers¶

- Organization: QuTech-Delft- Description: A provider for the Quantum Inspire backend- Qiskit Version: 0.7- More info: Medium Blog and Github.
Transpiler¶
Circuit optimization is at the heart of making quantum computing feasible on actual hardware. A central component of Qiskit is the transpiler, which is a framework for manipulating quantum circuits according to certain transformations (known as transpiler passes). The transpiler enables users to create customized sets of passes, orchestrated by a pass manager, to transform the circuit according to the rules specified by the passes. In addition, the transpiler architecture is designed for modularity and extensibility, enabling Qiskit users to write their own passes, use them in the pass manager, and combine them with existing passes. In this way, the transpiler architecture opens up the door for research into aggressive optimization of quantum circuits.
Additional passes¶

Fri Apr 4 12:46:17 CEST 2008
hi,
I want to iterate over the current domain of a integer view
(Gecode::Int::IntView). How can I do that ? Is this domain current ?
I want to implement my own variable and value selection. That's why I
need to access the current domain of the variable. Is there any good way
to do it ?
With regards
Debdeep

Nokia Does Smart TVs Now
by Tegan JonesWhile terms like '3310' and 'Snake' come to mind when Nokia is mentioned, that may be about to change.
The smart phone company is getting into the smart TV game. Well, it's letting its name be slapped on one at the very least.
Indian company Flipkart has secured a licensing deal with Nokia for its new 55-inch smart TV.
It will have a 4K UHD screen with a 60Hz refresh rate and 400 nits of max brightness, Dolby vision and HDR10 support, two 24-watt JBL by Harman speakers, 16GB on-board storage, a quad-core processor, three HDMI ports, two USB-ports, Wi-Fi and bluetooth connectivity.
It will also run an Android 9 operating system with access to Google Play.
"The first-ever Nokia branded Smart TV with Sound by JBL is powered by 24 Watt built-in speakers, DTS TruSurround and Dolby Audio to enhance the overall audio experience at home," Flipkart said in a statement. "This feature addresses a major pain point among Indian consumers, many of whom except a better sound quality from their televisions today."
According to Gadgets 360, Flipkart has stated that its looking to sell more Nokia-branded TVs in the future, though there are no details as yet. We are also unsure if we will ever see them in Australia, though it seems unlikely.
The Nokia 55 Inch Ultra HD TV (4K) will launch in India on December 10 and will have an RRP of 41,999 Indian rupees, which is about $862.


When we consider a C++ program, it can be defined as a collection of objects that communicate via invoking each other's methods. Let us now briefly look into what a class, object, methods, and instant variables mean.
Let us look at a simple code that would print the words Hello World.
#include<iostream> using namespace std; // main() is where program execution begins. int main() { cont<< "Hello World"; // prints Hello World return 0; }
Let us look at the various parts of the above program:
Let's look at how to save the file, compile and run the program. Please follow the steps given below:
$ g++ hello.cpp $ ./a.out Hello World
In C++, the semicolon is a statement terminator. That is, each individual statement must be
ended with a semicolon. It indicates the end of one logical entity.
For example, following are three different statements:
x = y; y = y+1; add(x, y);
{ cout << "Hello World"; // prints Hello World return 0; }
x = y; y = y+1; add(x, y);
x = y; y = y+1; add(x, y);
A C++ identifier is a name used to identify a variable, function, class, module, or any other user-defined item. An identifier starts with a letter A to Z or a to z or an underscore (_) followed by zero or more letters, underscores, and digits (0 to 9).
Here are some examples of acceptable identifiers:mohd zara abc move_name a_123 myname50 _temp j a23b9 retVal

A few characters have an alternative representation, called a trigraph sequence. A trigraph is a three-character sequence that represents a single character and the sequence always starts with two question marks.
Trigraphs are expanded anywhere they appear, including within string literals and character literals, in comments, and in preprocessor directives.
| Trigraph | Replacement |

A line containing only whitespace, possibly with a comment, is known as a blank line, and
C++ compiler totally ignores it.
Whitespace is the term used in C++ to describe blanks, tabs, newline characters and
comments. Whitespace separates one part of a statement from another and enables the compiler to identify where one element in a statement, such as int, ends and the next element
begins. Statement 1:
int age;In the above statement there must be at least one whitespace character (usually a space) between int and age for the compiler to be able to distinguish them. Statement 2:
fruit = apples + oranges; // Get the total fruit
C++ supports single-line and multi-line comments. All characters available inside any
comment are ignored by C++ compiler.
C++ comments start with /* and end with */. For example:
/* This is a comment */ /* C++ comments can also * span multiple lines */A comment can also start with //, extending to the end of the line. For example:
#include <iostream> using namespace std; main() { cout << "Hello World"; // prints Hello World return 0; }When the above code is compiled, it will ignore // prints Hello World and final executable will produce the following result:
Hello WorldWithin a /* and */ comment, // characters have no special meaning. Within a // comment, /* and */ have no special meaning. Thus, you can "nest" one kind of comment within the other kind. For example:
/* Comment out printing of Hello World: cout << "Hello World"; // prints Hello World */

A handler for Proton messaging events.
Subclass and override the event-handling member functions.
There are several objects that have on_X_close
and on_X_error
functions. They are called as follows:
X
is closed cleanly, with no error status, then on_X_close
is called.X
is closed with an error, then on_X_error
is called, followed by on_X_close
. The error condition is also available in on_X_close
from X::condition()
.By default, if you do not implement on_X_error
, it will call on_error
. If you do not implement on_error
it will throw a proton::error exception, which may not be what you want but does help to identify forgotten error handling quickly.
Every on_X_open
event is paired with an on_X_close
event which can clean up any resources created by the open handler. In particular this is still true if an error is reported with an on_X_error
event. The error-handling logic doesn't have to manage resource clean up. It can assume that the close event will be along to handle it.

Preity Zinta shares picture from shooting of ‘Fresh Off The Boat’
The new episode starring Zinta and Vir Das, will centre around an Indian family whose daughter attends school with the main character of the sitcom
by IANSZinta is back in action and that too on on the American show Fresh Off The Boat.
Preity, who will feature as a guest star in an upcoming episode, has already starting shooting for the show.
Announcing her new project, she took to social media and wrote: “And so it begins....  It’s amazing how a change of scene can make you feel like a newcomer. Loving and absorbing it all.”
Along with it, she shared a mirror selfie clicked in her make-up room.
Set in the ‘90s, Fresh Off The Boat centers on hip-hop loving teenager Eddie Huang and his family, who have adjusted to Orlando and the suburban American lifestyle. Fresh Off The Boat is currently in its sixth season. India VJ-actor-comedian Vir Das is also a part of the show.
Zinta and Vir Das’ inclusion on the show is expected to serve as basis for a spin-off show tentatively titled Magic Motor Inn. The new episode starring the two Indian actors, will centre around an Indian family whose daughter attends school with Eddie.
Zinta will portray the girl’s mother Meena, while Das will essay the role of her father DC.
Apart from the sitcom, Preity will also be seen essaing a cameo role in Salman Khan’s Dabangg 3.

A friend of mine was prescribed to Adderall at the beginning of the second semester of the 2001 school year. I had graduated HS and have had a great summer thus far, its August and my friend Robert is having an end of year bash at his house.
I hadn't done many drugs before this night, mainly just drank, smoked alot of pot, and dabbled in Opium a few times. I had heard how great this pill makes you feel when you snort it so I decided to give it a try, why not, it is the last party of the summer.
So I had been drinking for about an hour maybe only 2 or 3 beers when my friend showed up with a full prescription bottle of the '30s' I bought 3 from him for like 4 bucks. I bumped one right off the bat and within 10 minutes I felt a high like I have never felt before. I tend to be a rather mellow person in nature but I had boundless energy and it felt like my mind was running at 200%. Before taking them he told me that snorting usually takes a lot less time to wear off then simply ingesting them. So me and another friend split my next two and, wow. My heart was racing and just about every sense was on fire. Music was absolutely beautiful to me all the lights in the room were far 'sparklier', and I wanted to have a conversation with just about everything that had 4 limbs.
Then I decided to chill out and go outside because the house was becoming very hot. If that was a product of the pills or just the 40 some-odd kids that were there I do not know. So a handful of us all sat down on the benches in Rob's backyard and smoked a blunt. I remeber quite vividly just sitting back and staring at the sky between hitting the blunt the stars were very fascinating but I became aware of how hard it became to concentrate on one train of thought, kind of like mushrooms but with less disassociation.
 My pupils were humongous, nearly engulfing the entire iris, but at least the intense heart pounding had lessened quite a bit.
In my abscence the Beruit table (beer pong) had been set up and I was set to play in about an hour. 'An hour?' I thought. Well I better buy some more Addys and sniff a few more lines so I am nice and ready for the game. A few lines turned into an all-out bakeoff of snorting pills. Since my mind was fairly sharp even when intensely messed up I estimate I had roughly 2 more pills worth of lines (maybe a bit more).
I step up to play Beruit and its almost as if only the table is the room, illuminated by abnormally bright and, again, sparkly lights. I would shoot the ball and 9 times out of ten it went in, I could feel my skill almost flow down from my eyes to brain to arm. The ball would leave an afterimage 'tail' of some sort behind it that was a warmer color than the stark white ball, like a trail leading directly to my great shot. I won about 6 games, which turned out to be around 6 more beers.
I sit down on the couch and the world is rushing through my head. Not room spinning like alchohol or dissorientation like shrooms, just as if my brain could finally handle all the outside info it was getting, and it was doing a pretty damn good job of it.
Subsequently I was moving into my new dorm room the following evening and before I could even notice I had the next week planned out. Not like generalizations or anything, but even lunches and naps were included. Weird since I am so very unorginized and rarely plan father than a few hours in advance of my life. When I came to this realization of what I had been doing all I felt was my heart beating.
I didn't really freak out but I moved fast to the bathroom to get some water since my mouth was a veritable Sahara Desert. I looked in the mirror an my iris' were no longer viewable. I got right up close to the mirror to see if I could actually see my iris and got transfixed on the sparkling little spots of light on my pupil. The rest of the room darkened considerable and all I could do was focus on these little points of beautiful light. This was not scary at all, but entirely the opposite I was almost overjoyed to be experiencing such things.
The rest of the night was uneventful, other than talking to just about everyone at the party for upwards of 45 minutes at a time. They were all drunk so they enjoyed my over-enthusiasm. I went back home at around 6AM and as I was heading back the sun was rising, I was certainly under the influence of the drugs, but it was a more calm and retrospective feeling about the evening.
I got home, took a shower (which felt great), and lay down for some sleep in my bed. As I soon found out sleep was the most impossible thing to attempt at the time. My heart was still pounding, and every 10 seconds or so I would involutarily open my eyes and then curse myself for not just keeping them shut and falling asleep. When I could manage to keep my eyes shut all I could focus on was the strong and fast beating of my heart, which was as annoying and diruptfull as blaring music at 6:30AM. Even when I did finally concentrate and slow my heartbeat to acceptable levels anything would set it racing again. That consisted of wind, pipes popping, creaking, even the sound of my hair on the pillow. Also any sort of thought that related to the future and my starting college career would set it racing again.
I didn't sleep at all, I was awake when my dad yelled down to me it was time to get up and get moved into my dorm. Moving in was interesting to say the least, I felt like a zombie but I had to act like I was fine and great. My parents have no problem with booze or pot, but if they found out I snorted 5 misc. pills that were basically speed they would have killed me. The entire next day I just moped around and tried to nap, with the same results as before. It might have been around 4AM when I finally fell asleep in an utter delirious tired state.
The next day I felt fine, I was a little worn out but that can be expected. My heartbeat didn't return to normal for a few more days but it stayed at acceptable levels.
I have done Addys a dozen or so times after that but recently stopped due to tolerance to the drug, it almost wears off immediately and just leaves me with the ability to not sleep due to my heart pounding.
Thanks for reading!

Dear Dry,
Before 2015 ends, we want to ask you for a special tax-deductible, year-end contribution to keep “Ms.” on the frontlines reporting, rebelling, and truth-telling. [ https://org.salsalabs.com/o/1400/p/salsa/donation/common/public/?donate_page_KEY=13283 ]
It’s only with the support of dedicated individuals – like you – that “Ms.” can remain fiercely independent. Remember, “Ms.” is sustained by its readers and supporters – not by advertisers.
Because “Ms.” doesn’t take advertisements from corporate special interests, you never have to worry that we will shy away from telling it like it is. From shocking Supreme Court decisions allowing bosses to decide their women employees’ birth control, to campus sexual assault, to the War on Women, “Ms.” is the leader in reporting our lives.
This next year will be pivotal in the fight for women’s full equality. So we can move forward stronger than ever before in 2016, please make a special tax-deductible, year-end contribution to support “Ms”. [ https://org.salsalabs.com/o/1400/p/salsa/donation/common/public/?donate_page_KEY=13283 ]
With your support “Ms”. will remain a trusted source of news and analysis, ideas and inspiration for feminists – here and worldwide. We will continue to raise awareness and inspire our audiences to action, resulting in real and permanent change.
Your tax-deductible contribution [ https://org.salsalabs.com/o/1400/p/salsa/donation/common/public/?donate_page_KEY=13283 ] helps ensure “Ms.” continues to grow, inspire and educate as it renews and empowers each one of us.
Please give as generously as possible at this time of reflection and holiday cheer to help us meet the challenges ahead and make 2016 a year of impact and celebration. [ https://org.salsalabs.com/o/1400/p/salsa/donation/common/public/?donate_page_KEY=13283 ]
Wishing you a feminist Happy New Year!

NullValue
is a singleton enumeration to represent the null value for the
Value

The JSON representation for NullValue
is JSON null

Null value. |
Action describes which Handler to invoke and what data to pass to it for processing.
The following example instructs Mixer to invoke ‘prometheus-handler’ handler and pass it the object constructed using the instance ‘RequestCountByService’
handler: prometheus-handler
instances:
- RequestCountByService

Required. Name of the component producing these attributes. This can be
the proxy (with the canonical name “istio-proxy”) or the name of an
|
attributes |
map<string, AttributeManifest.AttributeInfo> |
The set of attributes this Istio component will be responsible for producing at runtime. We map from attribute name to the attribute’s specification. The name of an attribute, which is how attributes are referred to in aspect configuration, must conform to:
Where Attribute names must be unique within a single Istio deployment. The set of canonical attributes are described at https://istio.io/docs/reference/attribute-vocabulary.html. Attributes not in that list should be named with a component-specific suffix such as request.count-my.component |
AttributeInfo describes the schema of an Istio Attribute
.
Istio uses attributes
to describe runtime activities of Istio services.
An Istio attribute carries a specific piece of information about an activity,
such as the error code of an API request, the latency of an API request, or the
original IP address of a TCP connection. The attributes are often generated
and consumed by different services. For example, a frontend service can
generate an authenticated user attribute and pass it to a backend service for
access control purpose.
To simplify the system and improve developer experience, Istio uses shared attribute definitions across all components. For example, the same authenticated user attribute will be used for logging, monitoring, analytics, billing, access control, auditing. Many Istio components provide their functionality by collecting, generating, and operating on attributes. For example, the proxy collects the error code attribute, and the logging stores it into a log.
Each Istio attribute must conform to an AttributeInfo
in an
AttributeManifest
in the current Istio deployment at runtime. An
AttributeInfo
is used to define an attribute’s
metadata: the type of its value and a detailed description that explains
the semantics of the attribute type. Each attribute’s name is globally unique;
in other words an attribute name can only appear once across all manifests.
The runtime presentation of an attribute is intentionally left out of this specification, because passing attribute using JSON, XML, or Protocol Buffers does not change the semantics of the attribute. Different implementations can choose different representations based on their needs.
Because many systems already have REST APIs, it makes sense to define a standard HTTP mapping for Istio attributes that are compatible with typical REST APIs. The design is to map one attribute to one HTTP header, the attribute name and value becomes the HTTP header name and value. The actual encoding scheme will be decided later.
| Field | Type | Description |
|---|---|---|
description |
string |
Optional. A human-readable description of the attribute’s purpose. |
valueType |
istio.mixer.v1.config.descriptor.ValueType |
Required. The type of data carried by this attribute. |
Handler allows the operator to configure a specific adapter implementation.
Each adapter implementation defines its own params
proto.
In the following example we define a metrics
handler using the Mixer’s prepackaged
prometheus adapter. This handler doesn’t require any parameters.
name: prometheus-handler
adapter: prometheus
params:
| Field | Type | Description |
|---|---|---|
name |
string |
Required. Must be unique in the entire mixer configuration. Used by Actions to refer to this handler. |
adapter |
string |
Required. The name of a specific adapter implementation. An adapter’s implementation name is typically a constant in its code. |
params |
google.protobuf.Struct |
Optional. Depends on adapter implementation. Struct representation of a
proto defined by the adapter implementation; this varies depending on the value of field |
An Instance tells Mixer how to create instances for particular template.
Instance is defined by the operator. Instance is defined relative to a known template. Their purpose is to tell Mixer how to use attributes or literals to produce instances of the specified template at runtime.
The following example instructs Mixer to construct an instance associated with template ‘istio.mixer.adapter.metric.Metric’. It provides a mapping from the template’s fields to expressions. Instances produced with this instance can be referenced by Actions using name ‘RequestCountByService’.
- name: RequestCountByService
template: istio.mixer.adapter.metric.Metric
params:
value: 1
dimensions:
source: source.service
destination_ip: destination.ip
| Field | Type | Description |
|---|---|---|
name |
string |
Required. The name of this instance Must be unique amongst other Instances in scope. Used by Action to refer to an instance produced by this instance. |
template |
string |
Required. The name of the template this instance creates instances for. The value must match the name of the available template in scope. |
params |
google.protobuf.Struct |
Required. Depends on referenced template. Struct representation of a
proto defined by the template; this varies depending on the value of field |
ListValue
is a wrapper around a repeated field of values.
The JSON representation for ListValue
is JSON array.
| Field | Type | Description |
|---|---|---|
values |
Value[] |
Repeated field of dynamically typed values. |
A Rule is a selector and a set of intentions to be executed when the
selector is true
The following example instructs Mixer to invoke ‘prometheus-handler’ handler for all services and pass it the instance constructed using the ‘RequestCountByService’ instance.
- match: destination.service == "*"
actions:
- handler: prometheus-handler
instances:
- RequestCountByService
| Field | Type | Description |
|---|---|---|
match |
string |
Required. Match is an attribute based predicate. When Mixer receives a
request it evaluates the match expression and executes all the associated A few example match:
|

Action[] |
Optional. The actions that will be executed when match evaluates to |
Struct
represents a structured data value, consisting of fields
which map to dynamically typed values. In some languages, Struct
might be supported by a native representation. For example, in
scripting languages like JS a struct is represented as an
object. The details of that representation are described together
with the proto support for the language.
The JSON representation for Struct
is JSON object.
| Field | Type | Description |
|---|---|---|
fields |
map<string, Value> |
Unordered map of dynamically typed values. |
Value
represents a dynamically typed value which can be either
null, a number, a string, a boolean, a recursive struct value, or a
list of values. A producer of value is expected to set one of that
variants, absence of any variant indicates an error.
The JSON representation for Value
is JSON value.
| Field | Type | Description |
|---|---|---|
