CDL is a member of both organizations. CDL is a founding member of DataCite and one of the most active, with representation on the DataCite Board and the Metadata Working Group.
What is the EZID-to-Crossref service exactly?
For participating clients (see below), EZID registers DOIs for open access scholarly journal articles and other open access content, and then sends metadata about these items (provided by the clients) to Crossref. EZID manages the linkage to Crossref. Clients can submit records for this service using EZID's API (application programming interface). Clients can monitor the progress of submissions via messages from Crossref (sent by EZID).
What are the benefits to this service?
Crossref says their value proposition for journal publishers is this: "By joining this collaborative network, you will add reader utility to your digital content through outbound links to cited material, while augmenting access to your material through incoming links from other publishers."
To be specific, for most open access journal publishers, the number one benefit is the inclusion of their journal's metadata in the Crossref Metadata Services. Many organizations (listed here) subscribe to Crossref metadata, so your journal articles are instantly more discoverable.
Who is eligible to participate?
EZID clients with these characteristics:
If we don't have this type of account, can we upgrade?
In many cases, the answer is yes. Contact us to discuss this option.
What is the status of the EZID-Crossref "connection"?
This service is in production. If you are interested in participating, please contact us.
How much will it cost EZID clients to participate?
Crossref charges DOI deposit fees, and all such fees for the participating clients will be sent to California Digital Library (CDL) as the Sponsoring Member. CDL will cover these fees for time being, and then re-assess based on individual client volume. We reserve the right to pass through deposit fees for subsequent billing cycles, and we will share our decision process with you.
What do eligible clients have to do to participate?
Each client that wishes to participate in this service must agree to comply with Crossref requirements. These include:
In addition, there are a (very) few setup steps which we can discuss when you contact us about participating.

Non-linear least-square method.
Using a given optimization algorithm (default is conjugate gradient),
\[ min \{ r(x) : x in R^n \} \]
where \( r(x) = |f(x)|^2 \) is the Euclidean norm of \( f(x) \) for some vector-valued function \( f \) from \( R^n \) to \( R^m \),
\[ f = (f_1, ..., f_m) \]
with \( f_i(x) = b_i - \phi(x,t_i) \) where \( b \) is the vector of target data and \( phi \) is a scalar function.
Assuming the differentiability of \( f \), the gradient of \( r \) is defined by
\[ grad r(x) = f'(x)^t.f(x) \]

UK’s Labour promises radical change if it wins election
by The Associated PressLONDON — Britain’s main opposition Labour Party is launching its detailed platform for Britain’s Dec. 12 election as it tries to close an opinion-poll gap with the governing Conservatives.
The left-of-centre party is pledging higher public spending and a greater role for the state in housing, transport and the provision of utilities.
The party says Thursday’s manifesto will include pledges to build 150,000 new homes a year for social rent and create hundreds of thousands of “green jobs” to combat climate change.
Prime Minister Boris Johnson’s Conservatives accuse Labour of reckless spending and outmoded socialist ideas.
But Labour leader Jeremy Corbyn compares himself to President Franklin D. Roosevelt, whose “New Deal” helped tackle the Great Depression. Corbyn said Roosevelt “had to take on the rich and powerful in America to do it.”

Version of Desargues' Theorem

Page 6:
Desargues'
theorem.
[Actually
an aggregate of four theorems. See below.]
[Notations for points: A, B,
C; A', B', C'; P, Q, R]
If two triads of points, A, B, C and A', B',
C',
be such that the three joining lines AA', BB', CC'
meet in one point, say O,
then the two lines BC, B'C' meet, say in the point P,
and similarly the lines CA, C'A' meet, say in Q,
and the lines AB, A'B' meet, say in R,
and the three points P, Q, R are in line.
Conversely, given two triads of points, A, B, C and A', B', C',
such that the lines BC, B'C' intersect, say in P,
that the lines CA, C'A' intersect, say in Q,
and that the lines AB, A'B' intersect, say in R,
while P, Q, R are in line,
then the lines AA', BB', CC' cointersect.
[PROOF]
It is supposed that the points A, B, C are not in line,
so that they determine a plane, and similarly that A', B', C' determine
a plane.
[Case
1: Different planes]
Take first the case when these planes are different.
Suppose further that no one of the joins BC,
CA,
AB is in the plane A'B'C',
and no one of the joins B'C', C'A', A'B' is in the plane ABC.
Then the fact that the lines BB', CC' intersect
involves that the points B, B', C, C' are in one plane,
and hence that the lines BC, B'C' meet.
[Definition
of points P, Q, R
]
Their point of intersection, say P,
lies then on BC which is in the plane ABC,
and on B'C' which is in the plane A'B' C',
so that P lies on the line of intersection of these two planes.
The point, Q, of intersection of the lines CA, C'A', similarly found,
as well as the point, R, of intersection of the lines AB, A'B',
are equally on the line of intersection of the planes ABC, A'B'C'.
So that the former
statement made is clearly true.
Conversely if the lines BC, B'C' meet in
the
point P,
while CA, C'A' meet in Q and AB, A'B' meet in R, then,
still assuming the planes ABC, A'B'C' to be different,
and assuming that no one of the lines BC, B'C', CA, C'A', AB, A'B'
is common to both planes, the points P, Q, R are evidently
in the line of intersection of these planes.
The fact that the lines BC, B'C' intersect,
involves that
the lines BB' and CC' intersect, while similarly
the line AA' intersects both of these.
Now the lines BB', CC' determine a plane,
and the line AA' does not lie in this plane,
since we have assumed that the planes ABC, A'B'C' are different;
wherefore the line AA' meets this plane in a point
and can only intersect both BB' and CC' by passing through their
Page 7:
point of intersection.
Thus
the lines AA', BB', CC' meet in a point, as we desired to
shew.
We have explicitly excluded, for
the
sake of simplicity,
the possibility of one of the six lines BC,... lying in both planes,
which is easily seen to be unimportant.
Incidentally we see that if
three
lines be
such that every two of them have a common point,
then the three lines lie all in one plane,
or pass through one point.
[Case
2: One plane]
Next suppose the two triads A,
B, C
and A', B', C' to be in one plane,
it being assumed as before that
A, B, C are not in line and A', B', C' are not in line.
[Definition
of points O, P, P']
Then, first, let the lines AA',
BB',
CC' meet in one point, O.
Draw through O any line not
lying in
the plane of the two triads,
and let P, P' be any two points on this line.
[Definition
of points A", B", C"]
Then the intersecting lines AA'O and PP'O
determine a plane,
and the lines AP, A'P', lying therein, intersect in a point, say A".
Similarly the lines BP, B'P' meet in a point, say B",
and the lines CP, C'P' meet in a point, say C".
As P is not in the plane of ABC, A'B'C', it is clear that
the points A", B", C" are not in this plane;
further A", B", C" are not in line, since otherwise,
as the plane containing this line and P
would contain the points A, B, C, these would be in line;
finally the plane which is thus determined by the points A", B", C"
does not contain, for instance, the line AB,
for otherwise the plane of AB and A"B",
which contains P, would contain C" and C,
and A, B, C would be in line.
[Definition of points L, M, N]
Hence it follows from what is proved above,
as the lines AA", BB", CC" meet in P,
that there is, in the plane of ABC and A'B'C', a line,
where this plane is met by the plane A"B"C",
and upon this line three points, say L, M and N,
such that the lines BC, B"C" meet in L,
the lines CA, C"A" meet in M
and the lines AB, A"B" meet in N.
The point L is then the point where
the plane of ABC and A'B'C' is met by the line B"C",
and M, N are similarly the points where
this plane is met by C"A" and A"B".
By considering that the three lines A'A", B'B", C'C" meet in the point
P',
we prove however, in the same way, that B'C' passes through L,
and that C'A', A'B' respectively pass through M and N.
We have thus proved
that if two triads of points ABC, A'B'C', in the same plane,
be such that the joining lines AA', BB', CC' meet in a point,
then the three points of intersection
(BC, B'C'), (CA, C'A'), (AB,
A'B') are in line.
Conversely,
for two triads of points ABC, A'B'C' in the same plane,
assume that the three points
(BC, B'C'), (CA, C'A'), (AB, A'B') are in
line.
[Definition of points L, M, N for the converse]
Denote these points respectively by L, M, N.
Draw through the line LMN a plane,
other than the original plane of ABC, A'B'C';
draw through the points L, M, N, in this new plane, respectively
the lines LB"C", MC"A", NA"B", giving by their intersections
a further triad A", B", C" in this new plane.
This new plane does not contain any one of the lines BC, CA, AB, B'C',
Page
8:
C'A', A'B', and it
is
supposed that the lines LB"C", MC''A", NA"B"
are all drawn so as not to lie in the original plane of ABC, A'B'C'.
Then, as the lines BC, B"C" meet in the point L,
the lines CA, C"A" meet in the point M,
and the lines AB, A"B" meet in the point N,
[Definition of points O, P, P' for the converse]
it follows from what has preceded that
the three lines AA", BB', CC" meet in a point, say P,
which does not lie in either the original plane or the new plane.
It follows similarly, as the lines B'C', B"C" meet in the point L,
and C'A', C"A" in M, and A'B', A"B" in N,
that the lines A'A'", B'B", C' C" meet in a point, say P',
not lying in either of the two planes described.
Now let O be the
point where the line PP'
meets the original plane of ABC, A'B'C'.
Then, since the lines AP, A'P' intersect, in the point A",
and the points A, A', P, P' are not in line, these lines determine a
plane,
and therefore the line AA' intersects the line PP'.
This intersection can only be at O,
where the line PP' meets the original plane containing A and A'.
Thus the line AA' passes through O,
as, similarly, do also the lines
BB' and CC'.
We have thus proved
that if two triads ABC, A'B'C',
of points in one plane, neither triad being in line,
be such as to have three intersections
(BC, B'C'), (CA, C'A'), (AB, A'B') lying in line,
then the three joining lines AA', BB', CC' meet in a point.
The
aggregate of the
four
theorems now established
will be referred to as Desargues' theorem.

Popeyes employee, customer throw trays at each other in fight caught on video
by Gerren Keith GaynorTrays were sent flying at a Popeyes restaurant in San Antonio on Tuesday during a fight between a customer and an employee.
The two unidentified women are seen throwing food trays at each other in a dispute caught on video and posted on Twitter.
The woman who filmed the altercation said she was in line to pick up some of Popeyes’ popular chicken sandwiches when a woman who she believes was initially in the drive-thru line came in through a side door.

POPEYES FIGHT BREAKS OUT IN MARYLAND AS CUSTOMERS WAIT IN LINE FOR POPULAR CHICKEN SANDWICH
"I'm not really sure what happened but the lady and the employee were yelling at each other and the cashier just started throwing trays," the woman, identified as Valerie, told KSAT.
She said the employee also threw what appeared to be tea at the customer.

A man wearing a veteran’s hat is seen in the video holding the customer back and pulling her away.
"The veteran took the lady outside and the manager followed them outside ... and they physically got into a fistfight," Valarie said of the customer and manager.

That altercation wasn't caught on video, she said.
The tray melee happened just one day before a man was stabbed to death outside of a Popeyes restaurant in Maryland.
Police say the stabbing occurred after an altercation that began when one of the men cut a special line reserved for the much sought-after chicken sandwich.


3.2.11. Extensions for JUnit 5¶
Table of Contents
<IP_ADDRESS>. Overview¶
This section describes the extensions for using the automated testing framework in tests written in JUnit 5. By using this extension, you can combine the useful features provided by JUnit 5 such as parameterized tests with the automated testing framework.
Tip
There is no need to modify the tests of the existing the automated testing framework written in JUnit 4 when this extension is introduced. Tests written in JUnit 4 can continue to run on JUnit 5 by using JUnit Vintage (see Running The Automated Testing Framework with JUnit 5 for information on how to use JUnit Vintage to run an automated testing framework). Therefore, you can leave tests written in JUnit 4, and write new tests in JUnit 5,
<IP_ADDRESS>. Prerequisite¶
In order to use JUnit 5, the following conditions must be met.
- Java 8 or higher
- maven-surefire-plugin must be 2.22.0 or higher
This page assumes that you have basic knowledge of how to introduce JUnit 5 and how to create test cases, so it does not describe these procedures. For more information about JUnit 5 itself, see the official user guide (external site).
<IP_ADDRESS>. Module list¶
<dependency>
<groupId>com.nablarch.framework</groupId>
<artifactId>nablarch-testing-junit5</artifactId>
<scope>test</scope>
</dependency>
<IP_ADDRESS>. Basic usage¶
The automated testing framework provides classes that implement the functionality required for testing, such as TestSupport. In JUnit 4, in order to use the functionality of the classes provided by the automated testing framework in your test classes, your test classes had to inherit from these classes.
This extension provides a mechanism to generate instances of the classes provided by the automated testing framework on the extension side and inject them into the test classes. This mechanism makes use of the JUnit 5 Extension (external site).
In this extension, Extension classes and Composed annotations are provided for each class provided by the automated testing framework. For example, TestSupportExtension and NablarchTest are provided for TestSupport.
Tip
Composed annotation is a feature provided by JUnit 5 that allows you to combine the settings of multiple annotations into one annotation. For more information, see “2.1.1. Meta-Annotations and Composed Annotations” in the official guide (external site).
By using these classes and implementing them as follows, TestSupport can be used in tests.
// 1. Set the corresponding composed annotation to the test class
@NablarchTest
class YourTest {
// 2. Declare the field of class to be used in the test class.
TestSupport support;
@Test
void test() {
...
// 3. Use in tests
Map<String, String> map = support.getMap(sheetName, id);
...
}
}
When using TestSupport in a test class, first set the corresponding composed annotation (NablarchTest) in the test class. This will cause TestSupportExtension to be applied to the test class.
Next, declare an instance field of type TestSupport in the test class. The visibility of the instance field can be anything.
The extension creates an instance of the corresponding class (in this case TestSupport) before executing the test. Then, when it finds a field that can be assigned to the test class, it automatically injects an instance.
Warning
Don’t set any value to the field, because the extension will terminate in error if the field it be injected is not null.
<IP_ADDRESS>. List of Extension classes and composed annotations¶
This extension provides the following Extension classes and composed annotations.
<IP_ADDRESS>.1. Supplemental information on using BasicHttpRequestTest¶
Except for BasicHttpRequestTestTemplate, you can use it in the way described in Basic usage. It can be used in the way described in Basic usage.
Only BasicHttpRequestTestTemplate needs to specify parameters when using BasicHttpRequestTest, which is a composed annotation, so we will supplement it.
// 1. Specify the baseUri of BasicHttpRequestTest
@BasicHttpRequestTest(baseUri = "/test/")
class YourTestClass {
// 2. The method of injecting BasicHttpRequestTestTemplate is the same as the others.
BasicHttpRequestTestTemplate support;
@Test
void test() {
support.execute();
}
}
The BasicHttpRequestTest annotation needs to set the baseUri
.
This value corresponds to the value returned by the getBaseUri()
method of AbstractHttpRequestTestTemplate.
<IP_ADDRESS>. Add your own extensions¶
Describe how to extend the classes provided by the automated testing framework.
Tip
The procedure described here can also be applied to existing your own extension classes written in JUnit 4.
When creating your own extension classes, the following are the major steps to take.
- Inherit the classes provided by the automated testing framework and create your own extended classes
- Create the Extension for your own extension that inherits from the Extension corresponding to the class from which it inherits, and implement it to create an instance of your own extension class.
- Apply the Extension for your own extension to the test class using the
ExtendWith
annotation.
<IP_ADDRESS>.1. Create your own extension class¶
In this section, we will use the case of creating a class that extends TestSupport as an example.
First, create your own extension class that inherits from TestSupport.
public class CustomTestSupport extends TestSupport {
// Implement the constructor to pass the Class instance of the test class to TestSupport.
public CustomTestSupport(Class<?> testClass) {
super(testClass);
}
// Implement your own extension methods
}
Basically, the classes provided by the automated testing framework need to be passed the Class
object of the test class when instantiating.
Therefore, you need to define a constructor of your own extension class that can accept Class
objects of the test class.
Tip
SimpleRestTestSupport can be used without passing a Class
object of the test class to the constructor.
<IP_ADDRESS>.2. Create the Extension for your own extension¶
Next, create the Extension for your own extension by inheriting from the Extension class corresponding to the extension source class.
In the example, since it inherits from TestSupport, the corresponding Extension class will be TestSupportExtension.
Tip
If you use your own extension class that directly inherits from AbstractHttpRequestTestTemplate, you can use BasicHttpRequestTestExtension as the corresponding Extension.
public class CustomTestSupportExtension extends TestSupportExtension {
// Override createSupport() and implement it to return an instance of your own extension class
@Override
protected TestEventDispatcher createSupport(Object testInstance, ExtensionContext context) {
return new CustomTestSupport(testInstance.getClass());
}
}
Override createSupport()
method in the Extension for your own extension.
Then, implement it so that it returns an instance of the your own extension class you just created.
Note that instances of your own extension class created by the createSupport()
method are stored in the support
instance field of TestEventDispatcher type defined in the parent class TestEventDispatcherExtension.
This field is protected
, so it can be referenced by subclasses.
<IP_ADDRESS>.3. Applying to the test class with ExtendWith¶
The Extension for your own extension can be applied to the test class using the ExtendWith
annotation.
An example implementation is shown below.
..
import org.junit.jupiter.api.extension.ExtendWith;
// 1. ExtendWith to apply the Extension for your own extension to the test class
@ExtendWith(CustomTestSupportExtension.class)
class YourTest {
// 2. Declare an instance field of your own extension class.
CustomTestSupport support;
@Test
void test() {
// 3.  When extending BasicHttpRequestTestTemplate, also create annotations¶
When extending BasicHttpRequestTestTemplate or AbstractHttpRequestTestTemplate, it is necessary to pass baseUri
to an instance of your own extension class.
Since ExtendWith
has no parameters other than the Extension class, you need to create your own annotations as well.
The following is an example of implementation in BasicHttpRequestTestTemplate.
public class CustomHttpRequestTestSupport extends BasicHttpRequestTestTemplate {
private final String baseUri;
// Implement baseUri so that it can be passed from outside.
public CustomHttpRequestTestSupport(Class<?> testClass, String baseUri) {
super(testClass);
this.baseUri = baseUri;
}
@Override
protected String getBaseUri() {
return baseUri;
}
}
First, create your own extension class by inheriting from BasicHttpRequestTestTemplate.
The constructor needs to have the parameters the Class instance of the test class and baseUri
.
Next, create a composed annotation for your own extension class.
import org.junit.jupiter.api.extension.ExtendWith;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
// Specify the Extension for your own extension to be created later.
@ExtendWith(CustomHttpRequestTestExtension.class)
public @interface CustomHttpRequestTest {
// Declare the baseUri
String baseUri();
}
In the composed annotation, declare baseUri
so that it can be passed.
The Extension for your own extension specified by ExtendWith
are implemented as follows.
public class CustomHttpRequestTestExtension extends BasicHttpRequestTestExtension {
@Override
protected TestEventDispatcher createSupport(Object testInstance, ExtensionContext context) {
// Obtaining annotation information from the test class
CustomHttpRequestTest annotation = findAnnotation(testInstance, CustomHttpRequestTest.class);
// Pass the baseUri information to the constructor of your own extension class
return new CustomHttpRequestTestSupport(testInstance.getClass(), annotation.baseUri());
}
}
The findAnnotation(Object, Class)
can be used to obtain information about annotations set in the test class.
This allows you to pass the value of baseUri
to your own extension class.
Finally, you can use your own extension class that inherits from BasicHttpRequestTestTemplate by implementing it as follows using your own composed annotation.
// Set your own composed annotation to the test class (also set baseUri)
@CustomHttpRequestTest(baseUri = "/custom/")
class YourTest {
// Declare the fields of your own extension class
CustomHttpRequestTestSupport support;
@Test
void test() {
// Use your own extension class in Tests
support.customMethod();
}
}
<IP_ADDRESS>.5. Implementing pre-processing and post-processing¶
In the Extension for your own extension, you can implement pre-processing and post-processing of tests by overriding the following methods.
- beforeAll
- beforeEach
- afterAll
- afterEach
In beforeAll
and afterAll
, you can implement pre-processing and post-processing for the entire test class.
And with beforeEach
and afterEach
, you can implement pre-processing and post-processing for each test method.
When overriding each method, it is always necessary to execute the same method of the parent class as follows. If not, the pre-processing and post-processing defined in the parent class will not be called.
@Override
public void beforeAll(ExtensionContext context) {
// Always execute the parent's method first.
super.beforeAll(context);
// Implement your own pre-processing
...
}
<IP_ADDRESS>.6. Reproducing the TestRule of JUnit 4¶
If you have your own extension class created in an existing project, and it uses the TestRule
of JUnit 4, this section explains how to port it to this extension.
For example, suppose that the following your own extension class exists.
import org.junit.Rule;
import org.junit.rules.Timeout;
import java.util.concurrent.TimeUnit;
public class CustomTestSupport extends TestSupport {
// Using the TestRule of JUnit 4
@Rule
public Timeout timeout = new Timeout(1000, TimeUnit.MILLISECONDS);
public CustomTestSupport(Class<?> testClass) {
super(testClass);
}
}
When porting this to this extension, the Extension for your own extension is implemented as follows.
public class CustomTestSupportExtension extends TestSupportExtension {
@Override
protected TestEventDispatcher createSupport(Object testInstance, ExtensionContext context) {
return new CustomTestSupport(testInstance.getClass());
}
// 1. Override the resolveTestRules method
@Override
protected List<TestRule> resolveTestRules() {
// 2. Generate a list based on the result of resolveTestRules() of the parent class
List<TestRule> rules = new ArrayList<>(super.resolveTestRules());
// 3. Add the TestRule defined in your own extension class to the list
rules.add(((CustomTestSupport) support).timeout);
// 4. Return the generated list
return rules;
}
}
In the Extension for your own extension, you can override the method resolveTestRules()
.
Implement this method to return a list of the TestRules
of JUnit 4 that you want to reproduce.
This allows you to reproduce TestRule
of JUnit 4 on JUnit 5 tests.
Note that overriding resolveTestRules()
should always be based on the list returned by the parent class resolveTestRules()
.
If not, the TestRule
registered in the parent class will not be reproduced.
<IP_ADDRESS>. Using with RegisterExtension¶
JUnit 5 provides a mechanism called RegisterExtension to programmatically create an instance of Extension and apply it to a test class.
Tip
For an explanation of RegisterExtension, see “5.2.2. Programmatic Extension Registration” in the Official Guide (external site).
The Extensions provided by this extension can also be used with RegisterExtension.
However, in such a case, it must be used in a static field.
If used in an instance field, beforeAll
and afterAll
will not be executed, and the Extension will not work properly.
An example of implementation is shown below.
class YourTest {
// 1. Use RegisterExtension in static fields
@RegisterExtension
static TestSupportExtension extension = new TestSupportExtension();
// 2. Declare the instance field of the class provided by the automated testing framework
TestSupport support;
@Test
void test() {
// 3. Using support in tests
...
}
}

Recursion
So many good recursion gifs...
Recursion
-
Recursive functions invoke themselves repeatedly until some base case is
reached at which point a value is returned.
-
Recursion requires maintaining a stack which can be problematic in
languages that don't support
tail-call optimization
.
-
Some aspects of very deep recursion can be faked through the use of
higher-order functions. For example, the
y-combinator
can be represented both functionally and imperatively.
-
Looping in functional languages is usually accomplished via recursion.

| PM_TYPE pm_corridor_angle | ( | PMScan * | act | ) |
Determines the orientation of a corridor.
TODO: NEEDS A REWRITE - TOO MESSY.
Assuming the scan was taken of a corridor, determines the orientation of the corridor by finding the maximum in a 180 degree wide angle histogram. The input into the histogram are angles of lines created by connecting neighbouring points.
Normally, this function is used on the reference scan and not the current scan.
| act | The scan of which oriention is to be determined. |
| void pm_cov_est | ( | PM_TYPE | err, | |
| double * | c11, | |||
| double * | c12, | |||
| double * | c22, | |||
| double * | c33, | |||
| bool | corridor, | |||
| PM_TYPE | corr_angle | |||
| ) |
Estimates the covariance matrix of a match.
Estimates elements (c11,c12,c22,c33) of a match result covariance matrix of the following structure:
[c11 c12 0.0]
[c12 c22 0.0]
[0.0 0.0 c33]
This function scales a base covariance matrix by an error index:
C = C0(PM_MIN_STD_XY, PM_MIN_STD_ORIENTATION) * (err - PM_MATCH_ERROR_OFFSET).
For corridors it scales and rotates a covariance matrix stretched in the direction of the corridor:
C = Rot(C0, corr_angle) * (err - PM_MATCH_ERROR_OFFSET).
If (err - PM_MATCH_ERROR_OFFSET) < 1 then C = C0.
| err | The error index of the match. | |
| c11,c12,c22,c33 | The estimated covariance matrix elements. | |
| corridor | If true, a special estimate with large along-corridor-error is used. | |
| corr_angle | The orientation of the corridor. Call pm_corridor_angle on the refernce scan to get this value. |
Calculates an error index expressing the quality of a match.
This function assesses how well is the current scan aligned with the reference scan. This function has to be called after a scan has been matched. The current scan's pose has to be expressed in the reference scan's coordinate system.
The current scan is compared to the reference scan and vice versa, then the maximum is taken. The comparisson is performed by calculating the average closest point distance. Far away points are ignored in the process. The number of non-far away points have to be larger than a threshold.
This function is computationally very expensive and takes a conservative guess on the match quality.
TODO: Improve the accuracy of the estimate. Speed it up. Perhaps should use the error output from scan matching instead. A proper test is necessary.
| lsr | The reference scan. | |
| lra | The current scan. |
More quickly calculates an error index expressing the quality of a match.
This function assesses how well is the current scan aligned with the reference scan. This function has to be called after a scan has been matched. The current scan's pose has to be expressed in the reference scan's coordinate system.
The current scan is compared to the reference scan by projecting the current scan where the reference scan was taken and calculating the average range residuals.
| lsr | The reference scan. | |
| lra | The current scan. |
Matches two laser scans using the iterative closest point method.
Minimizes least square error of points through changing lsa->rx, lsa->ry, lsa->th by using ICP. It interpolates associated points. Only the best 80% of points are used in the pose calculation. Scan projection is done at each iteration.
For maintanence reasons changed scan projection to that of psm.
| void pm_init | ( | const char * | filename, | |
| FILE ** | fin | |||
| ) |
Initialises internal variables and opens a log file.
If filename is present, then it opens the scanfile and reads out the first line. The file pointer is then set to the corresponding file. Before performing any scan matching call this fuction once to initialize important global variables.
Upon failure an exception is thrown.
| filename | The name of the optional logfile to be used. | |
| fin | The optional opened file pointer is returned here. |
| bool pm_is_corridor | ( | PMScan * | act | ) |
Guesses if a scan was taken on a corridor.
Scan matching results on corridors are often inaccurate in the along-corridor direction. By detecting scans with a corridor-like appearance one can tailor a covariance matrix to incorporate the along-corridor uncertainty of the scan matching result.
Calculates the variance of angles between neighbouring Cartesian points as the "corridorness" criterion. On corridoors, the majority of vectors connecting neighbouring points are aligned along one line. Thus corridors generate a sharp peak in an angle histogram.
To solve the problem caused at the 180-0 degree transition point the calculations are repeated after a 30 degree shift. This is a hack which can be fixed easily.
The scan is assumed be pre-processed (segmentation and median filtering).
An exeption is thrown if there is less than 1 valid point.
TODO: Remove the double calculation of the variance.
| act | The scan which is examined for being corridor-like. |
| void pm_plotScan | ( | PMScan * | ls, | |

Generates a convergence speed plot from previously saved result.
If you want to see the convergence speed, then uncomment the definition of PM_GENERATE_RESULTS, recompile, match a scan and run this function.
Only works if PM_GENERATE_RESULTS was enabled in the previous match as only then are results saved in a file which is read here.
| xt | The true X coordinate where the solution should converge. | |
| yt | The true Y coordinate where the solution should converge. | |
| tht | [degrees] The true orientation where the solution should converge. |
| void pm_preprocessScan | ( | PMScan * | ls | ) |
Prepares a scan for scan matching.
Filters the scan using median filter, finds far away points and segments the scan.
| ls | The scan to be preprocessed. |
Match two laser scans using polar scan matching.
Minimizes the sum of square range residuals through changing lsa->rx, lsa->ry, lsa->th. The error is minimized by iterating a translation estimation step followed by an orientation search step.
PSM was not explicitly designed for laser scan matching based odometry where scans with small pose difference are matched with each other without any prior pose information. However when using PSM for this purpose, reduce the values of PM_MAX_ERROR, PM_WEIGHTING_FACTOR to reflect the small inter-scan motion. Also by reducing the value of PM_STOP_COND, larger matching accuracy can be achieved. The currently implemented error estimation functions are not useful for laser odometry error estimation.
Limitations: due to the nature of the association rule divergence in a slow rate may be experienced in rooms where there are not many features to constrain the solution in all directions. This can occur for examples in corridor-like environments including rooms where the room directly in front of the laser is outside of the range of the laser range finder.
| lsr | The reference scan. | |
| lra | The current scan. |
| int pm_readScan | ( | FILE * | fin, | |

A select allows the user to select one item from a list of options. A select is exactly the same as a normal HTML select (because it is one), but Skin's version uses a wrapper to style it.
The purpose of a select is to collect form data; therefore a select should always be used in conjunction with a form, label and submit button. If you are not submitting form data, then a menu maybe a better choice.
IMPORTANT: The examples below show the select in isolation, without any label. Please see the field module for details on labeling controls. Remember: every select requires a label!
If no suitable default value exists, the first option in the list can be used as a prompt and set to disabled & selected.
For a large select, apply the select--large modifier.


Holiday gift guide recommendations
I'm providing a compiliation of products that I personally own and love. I think if you try them you'll love them as well.
For the techy
Raspberry Pi™ 2 Model B 1GB
There are many like it, but this is what mine looks like. I think this sweet timber version of the pibow case is not in production anymore, but you'll find a ton of great cases, and you can even make your own with an altoids tin if you're feeling extra frugal.
The Pi 2 Model B (quad core processor) will run you:
~$35
Ducky Shine 4/5
If you work at a computer for hours a day, you are doing yourself a disservice not using a mechanical keyboard. I use both the ducky 4 and a DasKeyboard for Mac, and I like them both for different reasons. The great thing about the shine is the sweet backlighting and all the different modes you can play with. (I prefer the Cherry MX Blues) Prices are typically ~$165
Das Keyboard
This is another great keyboard, and it was my first mechanical keyboard (I had the older version). It is one of the only keyboards with a Mac layout that you'll find, and it performs great. The built in 2 port USB hub is a great addon that I miss with my Ducky.
$149
Uplift Standing Desk
I spent months pouring over prices and specs before I settled on the Uplift. This was a big purchase for me, and I was really nervous about spending this much on a desk I might not like. I have used the desk for a year now, and I absolutely love it. They allow many customizations when placing your order (power grommits in the desk are awesome).
$599
For the Outdoorsman
CRKT Minimalist Neck Knife
I like knives. You won't find a more useful or more comfortable knife at this price point. It feels great in the hand, holds an edge well, and comes in a few different blade shapes.
$35
Numyth Tohil v2 Watertight Lighter
You should always have a way to start fire on you, and what I love about this little keychain lighter is that it is water tight, which means the fluid won't evaporate. I filled mine up 6 months ago and have used it several times and it is still going, and if you have ever carried a zippo you know how fast they can lose their fluid to evaporation. The fit and finish of this is amazing machined aluminum.
$24
Thorfire Tactical Penlight
This is a great pocket light that runs on a single AAA battery. I have a couple of these, and for the price you won't find anything better. It feels substantial, and I like the tactial bezel and removable pocket clip.
$16
For Everyone
Aeropress Coffee Maker
I became a coffee snob this year, and this can be your first step to better coffee. You'll want a nice grinder and always use whole beans (try to find a local roaster if you can). This thing can make a great cup of coffee, is quick to clean, and cheap.
$30

I've just implemented an eval() call for MySQL. It is implemented with SQL, using a stored procedure. So this is not some plugin: you can use it from within your normal database server.
Just what is an eval() call?
In some programming languages it would mean: get some text, and execute it as though it were complied code. So, dynamic coding.
In SQL: get the text of query which generates SQL statements in itself (either DML or DDL), and invoke those implied SQL statements.
A simple example
Best if I present Mass killing of MySQL Connections by Peter Zaitsev. The thing is to execute a query, typically on INFORMATION_SCHEMA, which uses metadata so as to generate SQL queries/commands. Peter's example is:
select concat('KILL ',id,';') from information_schema.processlist where user='root'
The above query generates KILL commands for all users called 'root'. I do many such queries in common_schema: like creating the GRANT statements for accounts, the DROP KEY statements for redundant keys, the ADD and DROP statements for foreign keys etc.
So the problem is you have to export those statements to file, then execute them from file: either using SOURCE, as in Peter's example, or from shell prompt, piping file contents into mysql client.
You can now eval()
I've been on family holiday for a couple of weeks, which meant no need to think of work. Which means more time to think of SQL (darn!). And I've found the way to do it completely within the server (no external files required).
A usage example of eval() is this:
CALL eval('select concat(\'KILL \',id) from information_schema.processlist where user=\'root\'');
Note the changes:
- You pass your query as a string
- Consequently, you have to escape it
- No terminating ';' required
- You sit back and relax
The eval() procedure will:
- Execute the given query
- Expect it to return with exactly one textual column
- Expect text results to be valid queries or commands (i.e. UPDATE, DROP, KILL, ALTER, ...)
- Execute, in turn, each one of those statements
It will also require a temporary table. Thus, the user invoking eval() must have the CREATE TEMPORARY TABLES privilege, as well as any other privilege required for the supplied and implied queries. One typically executes eval() queries as a super user (e.g. 'root' account), so this should not be a problem.
This solution was made possible due to the fact that you can now send DDL commands via prepared statements. This makes for a very dynamic and versatile was to generate and execute queries and commands.
An execution example
Let's kill all queries running for more than 20 seconds, shall we?
<EMAIL_ADDRESS>SHOW PROCESSLIST; +----+------+-----------+---------------+---------+------+------------+---------------------+ | Id | User | Host | db | Command | Time | State | Info | +----+------+-----------+---------------+---------+------+------------+---------------------+ | 2 | root | localhost | common_schema | Query | 0 | NULL | SHOW PROCESSLIST | | 43 | apps | localhost | NULL | Query | 28 | User sleep | select sleep(10000) | +----+------+-----------+---------------+---------+------+------------+---------------------+ 2 rows in set (0.00 sec<EMAIL_ADDRESS>CALL eval('SELECT CONCAT(\'KILL \',id) FROM INFORMATION_SCHEMA.PROCESSLIST WHERE TIME > 20'); Query OK, 0 rows affected (0.01 sec<EMAIL_ADDRESS>SHOW PROCESSLIST; +----+------+-----------+---------------+---------+------+-------+------------------+ | Id | User | Host | db | Command | Time | State | Info | +----+------+-----------+---------------+---------+------+-------+------------------+ | 2 | root | localhost | common_schema | Query | 0 | NULL | SHOW PROCESSLIST | +----+------+-----------+---------------+---------+------+-------+------------------+ 1 row in set (0.00 sec)
Where is it?
It's part of common_schema, and I'm suggesting common_schema should appeal to anyone using or administrating a MySQL instance. There is a lot to this project in useful views & routines which help you out in analyzing and diagnosing your server, providing you with features the MySQL server itself does not provide.
If you just wish to browse eval()'s source code, it's here. eval()'s documentation is here, though if you've read thus far, you're covered.
An announcement on a new common_schema release will follow.

Sometimes you want to send an enormous amount of data to the client, much more than you want to keep in memory. When you are generating the data on the fly though, how do you send that back to the client without the roundtrip to the filesystem?
The answer is by using generators and direct responses.
This is a basic view function that generates a lot of CSV data on the fly. The trick is to have an inner function that uses a generator to generate data and to then invoke that function and pass it to a response object:
from flask import Response
@app.route('/large.csv')
def generate_large_csv():
def generate():
for row in iter_all_rows():
yield ','.join(row) + '\n'
return Response(generate(), mimetype='text/csv')
Each yield expression is directly sent to the browser. Now though that some WSGI middlewares might break streaming, so be careful there in debug environments with profilers and other things you might have enabled.
The Jinja2 template engine also supports rendering templates piece by piece. This functionality is not directly exposed by Flask because it is quite uncommon, but you can easily do it yourself:
from flask import Response
def stream_template(template_name, **context):
app.update_template_context(context)
t = app.jinja_env.get_template(template_name)
rv = t.stream(context)
rv.enable_buffering(5)
return rv
@app.route('/my-large-page.html')
def render_large_template():
rows = iter_all_rows()
return Response(stream_template('the_template.html', rows=rows))
The trick here is to get the template object from the Jinja2 environment on the application and to call stream() instead of render() which returns a stream object instead of a string. Since we’re bypassing the Flask template render functions and using the template object itself we have to make sure to update the render context ourselves by calling update_template_context(). The template is then evaluated as the stream is iterated over. Since each time you do a yield the server will flush the content to the client you might want to buffer up a few items in the template which you can do with rv.enable_buffering(size). 5 is a sane default.
New in version 0.9.
Note that when you stream data, the request context is already gone the moment the function executes. Flask 0.9 provides you with a helper that can keep the request context around during the execution of the generator:
from flask import stream_with_context, request, Response
@app.route('/stream')
def streamed_response():
def generate():
yield 'Hello '
yield request.args['name']
yield '!'
return Response(stream_with_context(generate()))
Without the stream_with_context() function you would get a RuntimeError at that point.
