Auxiliary MIDI input information.
- Gate
- 0 when Note Off, 1 when Note On. Trigger occurs on Note On.
- Note
- The pitch of the most recent MIDI Note. 0.0 ... 1.0 maps to MIDI note 0...127. Trigger occurs on Note On.
- Velocity
- The most recent attack (Note On) velocity value. 0.0 ... 1.0 maps to MIDI velocity 0...127. Trigger occurs on Note On
- Release
- The most recent release (Note Off) velocity value. 0.0 ... 1.0 maps to MIDI velocity 0...127. Trigger occurs on Note Off
- Pressure
- The current pressure (aftertouch) value. This responds to both channel and poly pressure. 0.0 ... 1.0 maps to MIDI velocity 0...127.
- Clock
- MIDI Clock. This triggers every single MIDI clock pulse. When the clock is running, the value is 1.0, else 0.0. When a MIDI START message is received, the clock will also go to 0.0 prior to the first pulse (at which point the clock is considered running, so it goes to 1.0). You will probably need to divide the MIDI clock pulse to something more useful for your purposes: for example getting a trigger every beat (every 24 pulses). To do something like this, try using the Trigger 2A through Trigger 192A options in the Mod Math module.
- Bend
- Current pitch bend information. 0.0 ... 1.0 maps to extreme bend low (-8192) to extreme bend high (8191). No bend is 0.5.
- CC n (eight of them)
- The dial sets the CC parameter. The output is the current value at that parameter, with 0...127 mapped to 0.0 ... 1.0. Trigger occurs when the CC value changes. CC values 6, 38, 98, 99, 100, and 101 are invalid: they are used by Flow for NRPN. If you need more than 8 CCs, just use a second MIDIIn module.

'Not really important' - Newcastle United star makes Aston Villa claim
Aston Villa v Newcastle United | The showdown between the two Premier League sides looms with Steve Bruce preparing to make his return to B6 after leaving last year
by Richard CusackNewcastle United pair Miguel Almiron and Allan Saint-Maximin retain the backing of their team-mates despite failing to score this season.
In a combined 20 appearances this season - nearly 1,500 minutes of football - the duo are yet to register.
Indeed, Almiron is yet to score since his January arrival from MLS side Atlanta United.
However, their profligacy in front of goal hasn't coincided with a drop in form for Steve Bruce 's side..
Aston Villa End of Decade Series
This week Birmingham Live are running a special series of articles looking back at the key moments from the last decade for Aston Villa.
Each day, there will be three new articles; one in the morning, one at lunchtime and one in the evening.
Here are some of the best bits so far...
- Team of the decade: 'Sure you'll agree' Aston Villa team of the decade and the players who missed out - revealed
- Ross McCormack and 'Gate Gate': 'You'll never get over it' - The moment that ruined this big Aston Villa transfer
- The making of Jack Grealish: 'Chewing on a naan bread' - The making of Jack Grealish in the words of his Dad
Magpies supporters on social media remain enthusiastic about playmaker Almiron despite his lack of goals.
Both he and Saint-Maximin have played in the past two matches - wins over West Ham United and AFC Bournemouth respectively.
Saint-Maximin assisted in the Bournemouth win last time out and is starting to have an impact after an injury his start to life on Tyneside having arrived from Nice in the summer.
Next up is a crucial visit to 17th placed Aston Villa on Monday night - just four points separate the two sides in the Premier League table.
“Sometimes, you just need the one goal, and it will come,” Dubravka told the Northern Echo.
“Miguel and Allan are working really hard, and the team effort is always there.
“It’s not really important who scores, but obviously it will be better for the strikers, for their confidence, to score some goals.
"At least we’re working really hard and creating chances, and hopefully it will come.”

I bought a new pencil today. Lost the last one so
I have no choise. Also I install slackware 13
(long time ago) at a flash drive and yesterday I
build a boot cd for it based on slackware 13 disk 1
cd. I mix the initrd of flash drive installation
with the slack cd, keeping only the kernels and
isolinux directories on new cd. The final iso gets
only 16mb and with root=/dev/disk parameters can boot a
lot stuff. :-)

/**
The REST adapter allows your store to communicate with an HTTP server by
transmitting JSON via XHR. Most Ember.js apps that consume a JSON API
should use the REST adapter.
This adapter is designed around the idea that the JSON exchanged with
the server should be conventional.
## Success and failure
The REST adapter will consider a success any response with a status code
of the 2xx family ("Success"), as well as 304 ("Not Modified"). Any other
status code will be considered a failure.
On success, the request promise will be resolved with the full response
payload.
Failed responses with status code 422 ("Unprocessable Entity") will be
considered "invalid". The response will be discarded, except for the
`errors` key. The request promise will be rejected with a `DS.InvalidError`.
This error object will encapsulate the saved `errors` value.
Any other status codes will be treated as an "adapter error". The request
promise will be rejected, similarly to the "invalid" case, but with
an instance of `DS.AdapterError` instead.
## JSON Structure
The REST adapter expects the JSON returned from your server to follow
these conventions.
### Object Root
The JSON payload should be an object that contains the record inside a
root property. For example, in response to a `GET` request for
`/posts/1`, the JSON should look like this:
```js
{
"posts": {
"id": 1,
"title": "I'm Running to Reform the W3C's Tag",
"author": "Yehuda Katz"
}
}
```
Similarly, in response to a `GET` request for `/posts`, the JSON should
look like this:
```js
{
"posts": [
{
"id": 1,
"title": "I'm Running to Reform the W3C's Tag",
"author": "Yehuda Katz"
},
{
"id": 2,
"title": "Rails is omakase",
"author": "D2H"
}
]
}
```
Note that the object root can be pluralized for both a single-object response
and an array response: the REST adapter is not strict on this. Further, if the
HTTP server responds to a `GET` request to `/posts/1` (e.g. the response to a
`findRecord` query) with more than one object in the array, Ember Data will
only display the object with the matching ID.
### Conventional Names
Attribute names in your JSON payload should be the camelCased versions of
the attributes in your Ember.js models.
For example, if you have a `Person` model:
```app/models/person.js
import DS from 'ember-data';
export default DS.Model.extend({
firstName: DS.attr('string'),
lastName: DS.attr('string'),
occupation: DS.attr('string')
});
```
The JSON returned should look like this:
```js
{
"people": {
"id": 5,
"firstName": "Zaphod",
"lastName": "Beeblebrox",
"occupation": "President"
}
}
```
#### Relationships
Relationships are usually represented by ids to the record in the
relationship. The related records can then be sideloaded in the
response under a key for the type.
```js
{
"posts": {
"id": 5,
"title": "I'm Running to Reform the W3C's Tag",
"author": "Yehuda Katz",
"comments": [1, 2]
},
"comments": [{
"id": 1,
"author": "User 1",
"message": "First!",
}, {
"id": 2,
"author": "User 2",
"message": "Good Luck!",
}]
}
```
If the records in the relationship are not known when the response
is serialized its also possible to represent the relationship as a
url using the `links` key in the response. Ember Data will fetch
this url to resolve the relationship when it is accessed for the
first time.
```js
{
"posts": {
"id": 5,
"title": "I'm Running to Reform the W3C's Tag",
"author": "Yehuda Katz",
"links": {
"comments": "/posts/5/comments"
}
}
}
```
### Errors
If a response is considered a failure, the JSON payload is expected to include
a top-level key `errors`, detailing any specific issues. For example:
```js
{
"errors": {
"msg": "Something went wrong"
}
}
```
This adapter does not make any assumptions as to the format of the `errors`
object. It will simply be passed along as is, wrapped in an instance
of `DS.InvalidError` or `DS.AdapterError`. The serializer can interpret it
afterwards.
## Customization
### Endpoint path customization
Endpoint paths can be prefixed with a `namespace` by setting the namespace
property on the adapter:
```app/adapters/application.js
import DS from 'ember-data';
export default DS.RESTAdapter.extend({
namespace: 'api/1'
});
```
Requests for the `Person` model would now target `/api/1/people/1`.
### Host customization
An adapter can target other hosts by setting the `host` property.
```app/adapters/application.js
import DS from 'ember-data';
export default DS.RESTAdapter.extend({
host: 'https://api.example.com'
});
```
### Headers customization
Some APIs require HTTP headers, e.g. to provide an API key. Arbitrary
headers can be set as key/value pairs on the `RESTAdapter`'s `headers`
object and Ember Data will send them along with each ajax request.
```app/adapters/application.js
import DS from 'ember-data';
export default DS.RESTAdapter.extend({
headers: {
'API_KEY': 'secret key',
'ANOTHER_HEADER': 'Some header value'
}
});
```
`headers` can also be used as a computed property to support dynamic
headers. In the example below, the `session` object has been
injected into an adapter by Ember's container.
```app/adapters/application.js
import DS from 'ember-data';
import { computed } from '@ember/object';
export default DS.RESTAdapter.extend({
headers: computed('session.authToken', function() {
return {
'API_KEY': this.get('session.authToken'),
'ANOTHER_HEADER': 'Some header value'
};
})
});
```
In some cases, your dynamic headers may require data from some
object outside of Ember's observer system (for example
`document.cookie`). You can use the
[volatile](/api/classes/Ember.ComputedProperty.html#method_volatile)
function to set the property into a non-cached mode causing the headers to
be recomputed with every request.
```app/adapters/application.js
import DS from 'ember-data';
import { get } from '@ember/object';
import { computed } from '@ember/object';
export default DS.RESTAdapter.extend({
headers: computed(function() {
return {
'API_KEY': get(document.cookie.match(/apiKey\=([^;]*)/), '1'),
'ANOTHER_HEADER': 'Some header value'
};
}).volatile()
});
```
@class RESTAdapter
@constructor
@namespace DS
@extends DS.Adapter
@uses DS.BuildURLMixin
*/
const RESTAdapter = Adapter.extend(BuildURLMixin, {
defaultSerializer: '-rest',
/**
By default, the RESTAdapter will send the query params sorted alphabetically to the
server.
For example:
```js
store.query('posts', { sort: 'price', category: 'pets' });
```
will generate a requests like this `/posts?category=pets&sort=price`, even if the
parameters were specified in a different order.
That way the generated URL will be deterministic and that simplifies caching mechanisms
in the backend.
Setting `sortQueryParams` to a falsey value will respect the original order.
In case you want to sort the query parameters with a different criteria, set
`sortQueryParams` to your custom sort function.
```app/adapters/application.js
import DS from 'ember-data';
export default DS.RESTAdapter.extend({
sortQueryParams(params) {
let sortedKeys = Object.keys(params).sort().reverse();
let len = sortedKeys.length, newParams = {};
for (let i = 0; i < len; i++) {
newParams[sortedKeys[i]] = params[sortedKeys[i]];
}
return newParams;
}
});
```
@method sortQueryParams
@param {Object} obj
@return {Object}
*/
sortQueryParams(obj) {
let keys = Object.keys(obj);
let len = keys.length;
if (len < 2) {
return obj;
}
let newQueryParams = {};
let sortedKeys = keys.sort();
for (let i = 0; i < len; i++) {
newQueryParams[sortedKeys[i]] = obj[sortedKeys[i]];
}
return newQueryParams;
},
/**
By default the RESTAdapter will send each find request coming from a `store.find`
or from accessing a relationship separately to the server. If your server supports passing
ids as a query string, you can set coalesceFindRequests to true to coalesce all find requests
within a single runloop.
For example, if you have an initial payload of:
```javascript
{
post: {
id: 1,
comments: [1, 2]
}
}
```
By default calling `post.get('comments')` will trigger the following requests(assuming the
comments haven't been loaded before):
```
GET /comments/1
GET /comments/2
```
If you set coalesceFindRequests to `true` it will instead trigger the following request:
```
GET /comments?ids[]=1&ids[]=2
```
Setting coalesceFindRequests to `true` also works for `store.find` requests and `belongsTo`
relationships accessed within the same runloop. If you set `coalesceFindRequests: true`
```javascript
store.findRecord('comment', 1);
store.findRecord('comment', 2);
```
will also send a request to: `GET /comments?ids[]=1&ids[]=2`
Note: Requests coalescing rely on URL building strategy. So if you override `buildURL` in your app
`groupRecordsForFindMany` more likely should be overridden as well in order for coalescing to work.

/**
Takes an ajax response, and returns the json payload or an error.
By default this hook just returns the json payload passed to it.
You might want to override it in two cases:
1. Your API might return useful results in the response headers.
Response headers are passed in as the second argument.
2. Your API might return errors as successful responses with status code
200 and an Errors text or object. You can return a `DS.InvalidError` or a
`DS.AdapterError` (or a sub class) from this hook and it will automatically
reject the promise and put your record into the invalid or error state.
Returning a `DS.InvalidError` from this method will cause the
record to transition into the `invalid` state and make the
`errors` object available on the record. When returning an
`DS.InvalidError` the store will attempt to normalize the error data
returned from the server using the serializer's `extractErrors`
method.

Johann Sebastian Bach (1685-1750) was music's most sublime creative genius. Bach was a German composer, organist, harpsichordist, violist, and violinist of the Baroque Era. Johann Sebastian Bach was born on March 21st 1685 in Eisenach, Germany. The young Bach was offered a choral scholarship to the prestigious St Michael's School in 1699.
1703 saw Bach become the organist at St Boniface's Church in Arnstadt - a role that saw him on a regular salary and expanding his skills at the keyboard. Bach composed the cantata Gott ist mein König in 1708 - he was paid handsomely, and it helped him cement his early career.
The Brandenburg Concertos were composed in 1721 as a sort-of musical job application for the Margrave Ludwig of Brandenburg - it was unsuccessful. In his later years Bach faced harsh criticism. During the 1720s and 1730s when he was composing his most important works - the Passions and the Goldberg Variations among them - a new Italian style invaded Germany, making his work appear outdated.
The Well Tempered Clavier, a quintessential student text, was finished in 1744 and comprised two volumes of piano music in every musical key. With the notable exception of opera, Bach composed towering masterpieces in every major Baroque genre: sonatas, concertos, suites and cantatas, as well as innumerable keyboard, organ and choral works.
Bach died on July 28th 1750 in Leipzig. It is still disputed whether it was a botched eye operation or a stroke caused by pneumonia were to blame for his death. Bach's popularity was decaying until 1829, when Mendelssohn performed the St Matthew Passion and rescued Bach from oblivion.
Little personal correspondence has survived to provide a full picture of Bach as a person. But the records do shed some light on his character. Bach was devoted to his family. In 1706, he married his cousin Maria Barbara Bach. The couple had seven children together, some of whom died as infants. Maria died in 1720 while Bach was traveling with Prince Leopold. The following year, Bach married a singer named Anna Magdalena Wülcken. They had thirteen children, more than half of them died as children.
Bach clearly shared his love of music with his children. From his first marriage, Wilhelm Friedemann Bach and Carl Philipp Emanuel Bach became composers and musicians. Johann Christoph Friedrich Bach and Johann Christian Bach, sons from his second marriage, also enjoyed musical success.


Lamar Jackson wins AFC Player of the Week
by Matthew ParasBaltimore Ravens quarterback Lamar Jackson was named AFC Player of the Week on Wednesday for his performance against the New England Patriots.
Jackson scored three touchdowns — one through the air, two on the ground — en route to handing New England its first loss of the season. The victory helped put Jackson in the MVP conversation as the league’s first-ranked defense had trouble stopping the shifty quarterback.
This is the second time Jackson has won the award this season. He also earned the honor in a Week 1 win over the Miami Dolphins, when he threw five touchdowns.
The Ravens are 6-2 in 2019, and sit atop the AFC North.

This methods uses the qutip module to visualise a qubit's superposition
on a bloch sphere.
This comes from the fact we can write any qubit in the form:
|phi> = e^ia*(cos(x/2)|0> + (e^iy)*sin(x/2)|1> )
and ignore the global phase e^ia, giving two angles (x,y) that we
can use to visualise any qubit uniquely

public key authentication
Scene Description
Public key authentication is a simple and efficient authentication mechanism between microservices provided by ServiceComb. Its security is based on the trust between microservices and service centers, namely microservices and service centers. The authentication mechanism must be enabled first. Its basic process is as follows:
- When the microservice starts, generate a secret key pair and register the public key to the service center.
- The consumer signs the message with his or her private key before accessing the provider.
- The provider obtains the consumer public key from the service center and verifies the signed message.
Public key authentication needs to be enabled for both consumers and providers.
servicecomb:
handler:
chain:
Consumer:
default: auth-consumer
Provider:
default: auth-provider
POM Dependency:
- Add dependencies in pom.xml:
<dependency>
<groupId>org.apache.servicecomb</groupId>
<artifactId>handler-publickey-auth</artifactId>
</dependency>
Configuring black and white list
Based on the public key authentication mechanism, ServiceComb provides a black and white list function. Through the black and white list, you can control which other services are allowed to be accessed by the microservice. Currently supported by configuring service attributes, the configuration items are as follows:
servicecomb:
publicKey:
accessControl:
black:
list01:
category: property ## property, fixed value
propertyName: serviceName ## property name
# property value matches expression.
# only supports prefix match and postfix match and exactly match.
#, e.g., hacker*, *hacker, hacker
rule: hacker
white:
list02:
category: property
propertyName: serviceName
rule: cust*
The above rules are configured with blacklists, which do not allow microservice names to be accessed by hackers; whitelists allow access to services with microservice names named cust.
ServiceComb provides [trust-sample] (https://github.com/apache/servicecomb-samples/tree/master/java-chassis-samples/trust-sample) to demonstrate the black and white list feature.

Electrity vs Gravity - Unfinished
At some point in your physics studies, you may have come across statements about gravity being very weak. Or electricity being a strong force when compared to gravity. I want to investigate these statements in a fun and interactive way. So first let us set the stage by quickly describing the AS/A level approach to gravity and electrostatic forces.
Interacting particles
The premise of two particles interacting is at the core to most of modern physics. However, the first thing we need do before diving into this problem is to take a closer look at the coordinate system we will be using. Gravity and electrostatic forces do not depend on the exact positions of the particles, only on their distance from each other. This means that a standard \((x,y)\) Cartesian coordinate system can be a little cumbersome. Where do we take our origin from? If we take the origin to be at the centre of one of the particles, we have to then deal with the circular or spherical symmetry of the system by introducing complicated coordinate expressions. It turns out that moving to a circular or spherical coordinate system will make everything much easier to describe.
So let us describe a circular coordinate systemThe generalisation to spherical coordinates will be
easy to understand after first working out the circular coordinate
system case.
. The first thing we need to do is to define a centre, a
\((r,\theta) = (0,0)\). We shall take
this to be at the centre of one of the particles. Then we need to define
where we measure the angle \(\theta\)
from? What is \(\theta=1^\circ\) for
instance? Well, consider two particles as in the diagram above, we can
always construct a line that connects the centres of the two particles.
We then measure the angle as being counterclockwise from this line.
Notice, that this definition has the added benefit for us, that the
angle-coordinate for one particle is always zero. This then captures the
idea that we only care about the separation of the particles, not the
exact position.Now if we have more than two particles in play, then
the case gets more complicated, so we will just ignore it for now.
Electrostatic Attraction and Repulsion
In order to investigate the relative strengths of gravity and electrostatic attraction/repulsion, we need to mathematically describe these forces. In order for there to be an electrostatic interaction, we need to have charged particles. Given two particles, \(p_1\) and \(p_2\), let them have charges \(q_1\) and \(q_2\) respectively.
Whether or not these particles experience an attractive force or a repulsive force, depends on the signs of the chargers. The strength of the force is reliant on the magnitude of these charges.
If these charges are both positive, or both negative, the particles will experience a repulsive force. The charges \(p_1\) and \(p_2\) have different signs, then the particles will experience an attractive force.
The electrostatic force between them can be expressed mathematically as: \[F_{\text{Elec}}= \kappa_0 {q_1 q_2 \over r^2}\] where \(r\) is the radial separation between the two objects. Note that a positive value for the force produces a repulsive force, and a negative value for the force results in an attractive force.
The coefficient \(\kappa_0\) is a constant, defined to be \(1/(4\pi\epsilon_0)\), where \(\epsilon_0\) is a measured quantity of nature called the “permittivity of the vacuum”. Essentially it is a measurement of how easily an electric field can travel through empty space. It is one of the fundamental physical constants of nature.
This coefficient \(\kappa_0\) plays
the vital role of rectifying the units of our expression. The value in
this work is takenThis value is derived from \(\kappa_0 = 1/(4π\epsilon_0)\) – “2018
CODATA Value: vacuum electric permittivity”. The NIST Reference on
Constants, Units, and Uncertainty. NIST. 20 May 2019. Retrieved
2019-05-20.
to be \(\kappa_0=8.9875517923(14)\times 10^9
\text{Nm}^{2}\text{C}^{-2}\).
Gravitation Attraction
\[F = - G {m_1 m_2 \over r^2} \]
The minus sign is because gravity is attractive and the mass is always positive. This is to aggree with the electricity convention above.
Overall force
\[F_{\text{Total}} = F_{\text{Grav}} + F_{\text{Elec}} = {(-Gm_1 m_2 + \kappa_0 q_1 q_2) \over r^2}\]
So if \(G m_1 m_2 = \kappa_0 q_1 q_2\), then overall force on the particles is zero, and they will be unaffected by electrostatics and gravity.
Specific Charge
Define the specific charge of a particle to be \(s_1 = q_1/m_1\). Then we have that \({G\over \kappa_0} = s_1 s_2\). So what is the value \(G/\kappa_0\)?
Hello
\[{\kappa_0 \over G} = 1.347459039\times 10^{20} \]
and
\[G/\kappa_0 = 7.42137587\times 10^{-21}\]

Can you help with this? I am having loop where I am parsing argument. My problem is that I don't know how to access the characters under (*it).
So I need to replace (*it)[n] for valid syntax used in C++03.
For example the (*it) refers to word "bla{y:12-15}blabla{x:124-}blabla"
other variations are "{y:12-15}blabla{x:124-}blabla" or "bla{y:12-15}blabla{x:124-}" or "{y:12-15}blabla{x:124-}"
so if it would be char * arg; I would refer it like arg[n] but I cannot do it with iterator. So I am curious how to do it correctly.
it++; i++; // read next argument
std::istringstream regex((*it));
int prefixn=0; // position of prefix
int sufixn=sizeof((*it)); // position of suffix
char * first; char * second;
for (int n=0; n<sizeof((*it)); n++){
if( (*it)[n] == '{')
{
if (!prefixn) // set the first position
{
prefixn=n;
for (; (*it)[n] <> '}'; n++)
first+=(*it)[n];
}
else
{
for (; (*it)[n] <> '}'; n++)
second+=(*it)[n];
}
}
if( (*it)[n] == '}')
{
sufixn=n; // set the last position
}
}
Is there way how to watch the value of (*it)[n] in Visual Studio during watch?
I can add (*it)[n] to Watch pan but it will display: Error: Overloaded operator not found
I am using this loop: for (std::vector<std::string>::iterator it = raw_args.begin(); it != raw_args.end(); ++it)
I want to get characters one by one from the vector.
Now I have this problem:
When prefix is char * = "";
and (*it) is some word, eg. "one"
and n is 0,
I need prefix to be set to "o". How to do it?
This:
prefix=prefix + (*it)[n];
sets prefix to "0"
