Superstar André Rieu returns to Liverpool in 2020
'The King of the Waltz' will be bringing his acclaimed Johann Stauss Orchestra back to the M&S Bank Arena on May 8, 2020
by Tom BramwellDubbed the Maestro of the Masses by the New York Times and The King of Crossover by the Wall Street Journal, André Rieu returns to Liverpool's M&S Bank Arena on May 8, 2020 for a magical evening of music and dance with his 70-piece Johann Strauss Orchestra. It’s the perfect event for the whole family!
With over 40 million album sales worldwide, André Rieu is one of the biggest music stars on the planet. His extraordinary performances include toe-tapping waltzes as well as some of the best-loved melodies from the worlds of film, opera and musicals.
André Rieu firmly believes that classical music is made for everybody to enjoy, not just for an elite. He makes beautiful classical music so much fun. At his concerts you can see his devoted audiences of all generations laughing, weeping, singing and dancing in the aisles.
Rieu established his Johann Strauss Orchestra in 1987 with just 12 members. Today it is the biggest privately-owned orchestra in the world. Each year they play for over 600,000 people around the world.
André Rieu also performed at the 1994, 2009 and 2019 Champions League Final soccer matches. His violin dates back to 1732. Rieu has reached 30 number 1 chart positions and won 500 platinum awards.
In May, he will bring his arena-sized show to Liverpool for one night only. Don’t miss your chance to see André Rieu live.

This is an advanced PhysicsJS example. Here's the code.
The scene is setup with circles that are given a "temperature" parameter that controls their buoyancy (vertical acceleration) with a custom buoyancy behavior.
A custom radiation behavior calculates the heat radiated and absorbed by each of the blobs. This is modeled as Black-body Radiation.
A large, fixed, hidden circle (with a high heat capacity) is placed just below the canvas. It acts as the "lamp" that heats up the blobs
The "blob" effect is created by a custom "metaball" renderer.


Lady Mafia
www.ladymafia.rocks
We want to change the narrative of women's history. Lady Mafia is a project to catalogue the impacts of women today and throughout history. Some you may have heard of, many that didn’t make into your history books, and all whose contributions to the world as we know it are powerful and maybe invisible; women who are making the world better, who are doing courageous things in the name of human flourishing.
The media has recently focused lots of attention on women, “women’s issues,” women in the work force, the deficit of women in tech fields, and almost glorifying women who have outstanding impact (you know, “for a girl”). The truth is, women have been rocking out for centuries. For one reason or another, they have been largely left out of history books, save for the token Marie Curies of each epoch that somehow make it in as the exception.
Women’s contributions have gone so undocumented and unnoticed that we are now supposed to believe that the days of great accomplishments by women represent a new chapter for humanity. Not so. Women have been the force behind scientific discoveries, the visionaries of art, the pioneers of literature, the first computer programmers, forensic scientists, and leaders of empires. They have been mothers and wives and spouses and friends and activists and even tyrants.
We aren’t documenting “women engineers,” or “female leaders,” or “girls-who-xyz.” We simply intend to create a catalogue of the awesome ways that humans around us - many who happen to be women - inspire us in their everyday actions. Whether subtle or bold, they are fierce. They are agents of change. They are the LADY MAFIA.

Media about the Model M
Across the internet, there are many articles and videos that cover the Model M. The most popular video about the Model M is from Linus Media Group which goes over the history of the IBM Model M, and its buckling-spring design.
If you are looking for a review on the Mini-M, the channel Chyrosran22 has a great video going over the model in the video below. The channel also cover other IBM keyboards in great detail, so I would suggest checking out his content.
If you want to read about the Model M instead, the verge released an article reviewing the New Model M from Unicomp listed here.

One solution starts out with the farmer bringing the chicken across and then return empty handed. The farmer then brings the bag of grain to the far side, but bringing the chicken back on the return trip. The farmer then brings the fox to the far side and return empty handed. Finally, the farmer brings the chicken across the river again, thus fulfilling the goal.
There is one other solution: once again the farmer starts by bringing the chicken across and then return empty handed. The farmer then brings the fox to the far side, but bringing the chicken back on the return trip. The farmer then brings the bag of grain to the far side and return empty handed. Finally, the farmer brings the chicken across the river again, thus fulfilling the goal.


In order to locate all relevant files, the following directory structure should be used.
myapp.exe sprt4-0-2.dll sp-4.0.2\ +--- bin\ | +--- sprt.sav +--- library\ +--- <files from %SP_PATH%\library>
If support for multiple SICStus instances is needed, the run-times named e.g. sprt4-0-2_instance_01_.dll need to be available as well, in the same place as sprt4-0-2.dll.
myapp.exe is typically created by a call to spld:
% spld --main=user [...] -o ./myapp.exe
If the directory containing sprt4-0-2.dll contains a directory
called sp-4.0.2
, SICStus assumes that it is part of a runtime system
as described in the picture below. The (extended) runtime library,
sprt.sav (spre.sav), is then looked up in the directory
(sp-4.0.2/bin), as in the picture. Furthermore, the initial
library_directory/1
fact will be set to the same directory with
sp-4.0.2/library
appended.
The directory structure under library/
should look like in a
regularly installed SICStus, including the platform-specific subdirectory
(x86-win32-nt-4
in this case). If your application needs to use
library(system)
and library(random)
, your directory
structure may look like:
myapp.exe sprt4-0-2.dll sp-4.0.2\ +--- bin\ | +--- sprt.sav +--- library\ +--- random.po +--- system.po +--- x86-win32-nt-4 \ +--- random.dll +--- system.dll
The sp*
files can also be put somewhere else in order to be
shared by several applications provided the sprt4-0-2.dll can be
located by the DLL search.
Naming the files with version number enables applications using
different SICStus versions to install the sp*
files in the same
directory.
When a runtime system is redistributed to third parties, only the following files may be included in the distribution. All filenames are relative to %SP_PATH%:

For much of the first week of Phase 0, I struggled to grasp the differences between margins, borders, and padding. I also didn't know how to use them correctly. The "box model" seems to be the best way of visually representing what each of these items are.
A Margin is the space in between individual HTML elements. Borders are barriers separating the margins from the padding. Padding is the space in between the actual content and the border. Within a CSS file, widths can be set for each of these.

AWT Threading Issues
Listeners and threads
Unless otherwise noted all AWT listeners are notified on the event dispatch thread. It is safe to remove/add listeners from any thread during dispatching, but the changes only effect subsequent notification.For example, if a key listeners is added from another key listener, the newly added listener is only notified on subsequent key events.
Auto-shutdown
According to The Java Virtual Machine Specification, sections 2.17.9 and 2.19, the Java virtual machine (JVM) initially starts up with a single non-daemon thread, which typically calls themain
method of some class.
The virtual machine terminates all its activity and exits when
one of two things happens:
- All the threads that are not daemon threads terminate.
- Some thread invokes the
exit
method of classRuntime
or classSystem
, and the exit operation is permitted by the security manager.
This implies that if an application doesn't start any threads itself,
the JVM will exit as soon as main
terminates.
This is not the case, however, for a simple application
that creates and displays a java.awt.Frame
:
public static void main(String[] args) { Frame frame = new Frame(); frame.setVisible(true); }The reason is that AWT encapsulates asynchronous event dispatch machinery to process events AWT or Swing components can fire. The exact behavior of this machinery is implementation-dependent. In particular, it can start non-daemon helper threads for its internal purposes. In fact, these are the threads that prevent the example above from exiting. The only restrictions imposed on the behavior of this machinery are as follows:
-
EventQueue.isDispatchThread
returnstrue
if and only if the calling thread is the event dispatch thread started by the machinery; -
AWTEvents
which were actually enqueued to a particularEventQueue
(note that events being posted to theEventQueue
can be coalesced) are dispatched:-
- Sequentially.
- That is, it is not permitted that several events from this queue are dispatched simultaneously.
-
- In the same order as they are enqueued.
- That is, if
AWTEvent
A is enqueued to theEventQueue
beforeAWTEvent
B then event B will not be dispatched before event A.
-
- There is at least one alive non-daemon thread while there is at
least one displayable AWT or Swing component within the
application (see
Component.isDisplayable
).
- The JVM will exit if some thread invokes the
exit
method of classRuntime
or classSystem
regardless of the presence of displayable components; - Even if the application terminates all non-daemon threads it started, the JVM will not exit while there is at least one displayable component.
Implementation-dependent behavior.
AWT terminates all its helper threads allowing the application to exit cleanly when the following three conditions are true:- There are no displayable AWT or Swing components.
- There are no native events in the native event queue.
- There are no AWT events in java EventQueues.
System.exit
must:
- Make sure that all AWT or Swing components are made
undisplayable when the application finishes. This can be done
by calling
Window.dispose
on all top-levelWindows
. SeeFrame.getFrames
. - Make sure that no method of AWT event listeners registered by
the application with any AWT or Swing component can run into an
infinite loop or hang indefinitely. For example, an AWT listener
method triggered by some AWT event can post a new AWT event of
the same type to the
EventQueue
. The argument is that methods of AWT event listeners are typically executed on helper threads.
- Other packages can create displayable components for internal needs and never make them undisplayable.
- Both Microsoft Windows and X11 allow an application to send native events to windows that belong to another application. With this feature it is possible to write a malicious program that will continuously send events to all available windows preventing any AWT application from exiting cleanly.
<...> Runnable r = new Runnable() { public void run() { Object o = new Object(); try { synchronized (o) { o.wait(); } } catch (InterruptedException ie) { } } }; Thread t = new Thread(r); t.setDaemon(false); t.start(); <...>The Java Virtual Machine Specification guarantees that the JVM doesn't exit until this thread terminates.


Class: Sprout::Executable::ParameterFactory
- Inherits:
-
Object
- Object
- Sprout::Executable::ParameterFactory
- Defined in:
- lib/sprout/executable/parameter_factory.rb
Overview
A factory to create concrete Sprout::Executable::Param entities from a set of known types.
If an unrecognized Class reference is provided we will instantiate it and ensure that it responds to the public members of the Executable::Param interface.
This Factory gives you the ability to create new, custom parameter types by simply ensuring they are available to Ruby before your executable is interpreted.
Following is an example of a custom Parameter:
class CustomParam < Sprout::Executable::Param
def to_shell
"--foo-bar=#{value}"
end
end
Following is an example Executable that can consume the above parameter:
require 'custom_param'
class Foo
include Sprout::Executable
add_param :name, CustomParam
end
That’s it, there is no need to register your custom types with the Factory, just get it into your load path and require it.
Class Method Summary (collapse)
-
+ (Object) create(type)
This factory allows us to use classes by reference in the Executable interface.
Class Method Details
+ (Object) create(type)
This factory allows us to use classes by reference in the Executable interface. Since there are already Ruby primitives for String and File and we don’t want to clobber them, we use this factory to convert those to the appropriate types.

Using Java Application Verification Kit
You can use the JavaTM Application Verification Kit (AVK) for the Enterprise to:
- Validate the packaging of WAR files, check method signatures, and generate report with inconsistencies.
- Validate the correct execution of Web and EJB components through introspection and instrumentation.
Steps for using AVK plug-in when your project uses Sun Java System Application Server 9.0 as runtime
- In the IDE, create a project or open an existing project.
For more information, see Project Tasks: Quick Reference.
- In the Projects window, select the project node, right-click and choose Verify Project.
The Choose Verification dialog box opens.
- Select the Dynamic Verification radio button and click OK.
The IDE deploys your project to the application server, starts the verification process, and brings up 'AVK Session' window in the editor pane showing the dynamic verification reports.
The reports in this window get automatically updated as you access your application.
- If your project has a web component then your application is launched in the browser. Otherwise, execute a sample manually outside the IDE.
- You will notice that the reports are automatically updated in 'AVK Session' window.
Note that 'Right Click' > 'Go To Source' on any 'Servlet Name' or 'Method Name' will open the appropriate source code.
'Right Click > 'Show Exception' on any exception of the unsuccessfully called Servet/EJB will show the exception stack trace on the output panel.
Steps for using AVK plug-in when your project uses Sun Java System Application Server 8.x as runtime
- In the IDE, create a project or open an existing project.
For more information, see Project Tasks: Quick Reference.
- Start the application server.
For more information, see SJS Application Server Tasks: Quick Reference.
- Enable Dynamic Verification.
- Deploy your project to the application server.
- Outside the IDE, execute a sample manually.
- In the IDE, generate and view the AVK report.
JavaTM AVK Installation Directories
The AVK plugin files are installed in different locations depending on whether you did a local or global installation.
- Local installation: ide-user-dir/modules
- Global installation: ide-install-dir/ide/jse8/modules
Additional Documentation
The complete user's guide for the JavaTM AVK is included with the installation. To access the user's guide, in the IDE, choose Help > Dynamic AVK Help.

fun4j brings functional programming to the JVM. It's a framework that integrates major concepts from functional programming into the Java Platform.
At its core there is a lambda-to-JVM bytecode compiler. Thanks to some optimization techniques like tail code optimization (TCO) the compiler produces code that runs as fast as hand optimized Java code. The compiler uses the excellent Java bytecode assembler ASM
On top of this compiler you'll find a functional Java framework featuring higher order functions, partial application, support for Collections and Iterators, lambda terms, closures, etc.
In fun4j functions can be defined as anonymous classes. But it's also possible to define functions as lambda terms in classical LISP syntax. This avoids all the Java boilerplate code and thus improves code readability. LISP and java functions are totally interoperable.
As programming in fun4j is so much fun, I've also added a small LISP Read-Eval-Print-Loop (REPL) to interactively work with fun4j. The REPL comes with a little libray of useful functions and some example programs. E.G. a Lispkit interpreter and a LISP-1.5 interpreter.
With release 1.1 the Java Lisp integration has much improved.
It's now possible to parse Vectors directly in Lisp code with the common[a, b, c]
or [a b c]
Notation.
There is now also a Dot
operator that allow to access Java classes and instances directly from Lisp code.
Please refer to the Java Lisp Integration tutorial for details.
Please check out the tutorial page for introductions to the main features.
When presenting fun4j to the public I received some sceptical comments like: "There's already functionaljava, guava, lambdaj, op4j, commons functor, etc.: why a new functional library ?" or "We have Scala, Clojure, etc. Why yet another functional language for the JVM?". In the following section I try to explain how fun4j differs from those tools and why it is relevant.
Most functional frameworks for Java provide sophisticated means to deal with functions and to use them to filter and transform collections and other Java data structures. But I don't know of any that provides a convenient way to define new functions from scratch. This is caused by the limitaions of the Java language: as of now it does not provide native support for defining closures.
All functional libraries that I know of work around this limitation by defining functions as Function objects that implement an apply
or evaluate
method.
Typically Function objects are then created in user code by defining anonymous inner classes, as in the following example:
Function add = new Function() { public Object apply(Object... args) { return (Integer) args[0] + (Integer) args[1]; } };
This is quite verbose and just does not feel right.
Fun4j is different, it allows to write functions as lambda-terms in classic Lisp syntax.
Thus the function add
from the above example can be defined in fun4j as follows:
Function add = fn("(lambda (x y) (+ x y))");
This Lisp function is internally compiled into Java bytecode and is thus fully interoperable with "normal" Java code. The cool thing about this is that you can still stick to Java as your main language and use Lisp as an "embedded language" to define Function objects.
Scala, Clojure and the like are meant as fullblown standalone programming languages. They introduce new concepts like STM, agents, actors, etc.
Fun4j does not aim at inventing a new language. Even though fun4j comes with a full Lisp compiler and an interactive REPL, it's not intended as a completely independent language as Clojure or Scala. It simply provides a minimalistic functional subset of Lisp (comparable to the classic LISPKIT). You can use this Lisp implemenation as a standalone language. But you can also use it as an "embedded language" to conveniently define functions when using the Fun4j Java API.
At the core of fun4j there is an AST based functional assembler that allows to compose functional expressions (or lambda-terms) and compile them into Java Bytecode. (Here's the tutorial covering the basics.) This Assembler is agnostic of the actually implemented language. So you could use it to write an implementation of your functional language of choice by simply adding a Parser.
That said, fun4j is not limited to implement Lisp only. It could be used to implement other functional languages as well.

Recall alert: Ski boots recalled due to cracking
by Natalie Dreier, Cox Media Group National Content DeskIf you're planning on hitting the slopes, check your gear. There's a ski boot recall that you need to know about.
SCARPA North America has recalled the Maestrale RS and Maestrale men's ski boots, the Consumer Product Safety Commission reported.
The recall affects the fall 2017 boots.
The Maestrale boots all have style number #12047/501.1 and are orange with SCARPA on the lower, outside shell. It also has Maestrale on the upper, outside cuff.
The Maestrale RS have style number #12046/501.1 and are white, black and lime. They also have SCARPA on the lower, outside shell and Maestrale on the upper, outside cuff.
The boots can crack and cause someone to fall. Skiers are being told not to use them and contact SCARPA for instructions on returning the boot for free repair.
The boots cost between $700 and $800 depending on the model and were sold from Aug. 2017 through Aug. 2019, the CPSC said.

Turkey returns 2 ancient artifacts to China
by ANADOLU AGENCYTurkey's Culture and Tourism Ministry has returned two heritage assets of China donated to a Turkish museum by a British citizen.
A ceremony was held at the Anatolia Civilizations Museum in the capital Ankara on Monday with the attendance of Culture and Tourism Minister Mehmet Nuri Ersoy and China's Ambassador to Ankara Deng Li.
Speaking at the ceremony, Ersoy said: "Each artifact is beautiful in its own lands, where it belongs, it is meaningful there. This is our respect for the essence of cultural assets."
Ersoy said Turkish authorities reached out to Chinese authorities after finding out that the artifacts belonged to them.
"One of the artifacts belongs to the Tang Dynasty which ruled from 618 to 907 A.D., and the statuette belongs to the Sui Dynasty that ruled between 557 and 618 A.D.," he said.
Ersoy also noted that the foreigner who donated the artifacts asked to remain anonymous. He had brought the assets to the Fethiye Museum in Muğla province of Turkey after finding it in his mother's house after her death.
Li thanked Turkey for the efforts to reinstate the cultural assets, adding that both countries have been cooperating on the issue of protecting cultural assets.
Following speeches from both sides, the return protocol was signed.

int MPI_Op_create(MPI_User_function *function, int commute, MPI_Op *op)
MPI_OP_CREATE( FUNCTION, COMMUTE, OP, IERROR)
EXTERNAL FUNCTION
LOGICAL COMMUTE
INTEGER OP, IERROR
void MPI::Op::Init(MPI::User_function* function, bool commute)
MPI_OP_CREATE binds a user-defined global operation
to an op handle that can subsequently be used in
MPI_REDUCE, MPI_ALLREDUCE,
MPI_REDUCE_SCATTER,
MPI_SCAN, and MPI_EXSCAN.
The user-defined operation is assumed to be associative.
If commute = true, then the operation should be both
commutative and associative. If commute = false,
then the order of operands is fixed and is defined to be in ascending, process
rank order, beginning with process zero. The order of evaluation can be
changed, talking advantage of the associativity of the operation. If
commute = true then the order of evaluation can be changed,
taking advantage of commutativity and associativity.
function is the user-defined function, which must have the following four arguments: invec, inoutvec, len and datatype.
The ISO C prototype for the function is the following.
typedef void MPI_User_function(void *invec, void *inoutvec, int *len, MPI_Datatype *datatype);
The Fortran declaration of the user-defined function appears below.
SUBROUTINE USER_FUNCTION(INVEC, INOUTVEC, LEN, TYPE)
<type> INVEC(LEN), INOUTVEC(LEN)
INTEGER LEN, TYPE
The C++ declaration of the user-defined function appears below.
typedef void MPI::User_function(const void* invec, void *inoutvec, int len, const Datatype& datatype);
The datatype argument
is a handle to the data type that was passed into the call
to MPI_REDUCE.
The user reduce function should be written such that the following
holds:
Let u[0], ... , u[len-1] be the len elements in the
communication buffer described by the arguments invec, len
and datatype when the function is invoked;
let v[0], ... , v[len-1] be len elements in the
communication buffer described by the arguments inoutvec, len
and datatype when the function is invoked;
let w[0], ... , w[len-1] be len elements in the
communication buffer described by the arguments inoutvec, len
and datatype when the function returns;
then w[i] = u[i]°v[i], for i=0 , ... , len-1,
where ° is the reduce operation that the function computes.
Informally, we can think of invec and inoutvec as arrays of len elements that function is combining. The result of the reduction over-writes values in inoutvec, hence the name. Each invocation of the function results in the pointwise evaluation of the reduce operator on len elements: I.e, the function returns in inoutvec[i] the value invec[i] ° inoutvec[i], for i=0, ... , count-1, where ° is the combining operation computed by the function.
Rationale.
The len argument allows MPI_REDUCE to avoid calling the function for each element in the input buffer. Rather, the system can choose to apply the function to chunks of input. In C, it is passed in as a reference for reasons of compatibility with Fortran.
By internally comparing the value of the datatype argument to
known, global handles,
it is possible to overload the use of a single user-defined function
for several, different data types.
( End of rationale.)
General datatypes may be passed to the user function.
However, use of datatypes that are not contiguous is likely to lead to
inefficiencies.
No MPI communication function may be called inside the user function. MPI_ABORT may be called inside the function in case of an error.
Advice to users.
Suppose one defines a library of user-defined reduce functions that are overloaded: the datatype argument is used to select the right execution path at each invocation, according to the types of the operands. The user-defined reduce function cannot ``decode'' the datatype argument that it is passed, and cannot identify, by itself, the correspondence between the datatype handles and the datatype they represent. This correspondence was established when the datatypes were created. Before the library is used, a library initialization preamble must be executed. This preamble code will define the datatypes that are used by the library, and store handles to these datatypes in global, static variables that are shared by the user code and the library code.
The Fortran version of MPI_REDUCE will invoke a user-defined reduce
function using the Fortran calling conventions and will pass a Fortran-type
datatype argument; the C version will use C calling convention and the C
representation of a datatype handle. Users who plan to mix languages should
define their reduction functions accordingly.
( End of advice to users.)
Advice
to implementors.
We outline below a naive and inefficient implementation of MPI_REDUCE
not
supporting the ``in place'' option.
MPI_Comm_size(comm, &groupsize); MPI_Comm_rank(comm, &rank); if (rank > 0) { MPI_Recv(tempbuf, count, datatype, rank-1,...); User_reduce(tempbuf, sendbuf, count, datatype); } if (rank < groupsize-1) { MPI_Send(sendbuf, count, datatype, rank+1, ...); } /* answer now resides in process groupsize-1 ... now send to root */ if (rank == root) { MPI_Irecv(recvbuf, count, datatype, groupsize-1,..., &req); } if (rank == groupsize-1) { MPI_Send(sendbuf, count, datatype, root, ...); } if (rank == root) { MPI_Wait(&req, &status); }The reduction computation proceeds, sequentially, from process 0 to process groupsize-1. This order is chosen so as to respect the order of a possibly non-commutative operator defined by the function User_reduce(). A more efficient implementation is achieved by taking advantage of associativity and using a logarithmic tree reduction. Commutativity can be used to advantage, for those cases in which the commute argument to MPI_OP_CREATE is true. Also, the amount of temporary buffer required can be reduced, and communication can be pipelined with computation, by transferring and reducing the elements in chunks of size len < count.
The predefined reduce operations can be implemented as a library of
user-defined operations. However, better performance might be
achieved if MPI_REDUCE handles these functions as a special
case.
( End of advice to implementors.)

int MPI_op_free( MPI_Op *op)
MPI_OP_FREE( OP, IERROR)

Marks a user-defined reduction operation for deallocation and sets
op to MPI_OP_NULL.
It is time for an example of user-defined reduction.
The example in this section uses an intracommunicator.
Example

Was a major change in syntax if you are googling you may older formats (they will still work)
export default function() {
console.log('Foo!');
}
import foo from 'foo';
foo(); // Foo!
//var is function scoped. - it gets hoisted up by JS.
if ( true ) {
var foo = 'bar';
}
console.log( foo ); // bar
//let and const are block scoped.
if ( true ) {
let foo = 'bar';
const bar = 'foo';
}
console.log( foo ); // ReferenceError.
console.log( bar ); // ReferenceError.
const variables can only be assigned once. It is NOT immutable (unchanging over time or unable to be changed).
const foo = { bar: 1 };
foo = 'bar';
// “foo” is read only.
//But, you can change the properties!
const foo = { bar: 1 };
foo = 'bar';
// “foo” is read only.
foo.bar = 2;
console.log(foo);
// { bar: 2 }
The only difference between const and let is that const makes the contract that no rebinding will happen.
Use var for top level variables (or not at all)
Use let for localized variables in smaller scopes.
Refactor let to const only after some code has been written and you’re reasonably sure there should’t be variable reassignment.
When using var, you leak a global variable to the parent scope and the variable gets overwritten with every iteration.
Messy... hard to keep track
More concise than traditional function expressions (but you can use either)
// Traditional function expression.
const addNumbers = function (num1, num2) {
return num1 + num2;
}
// Arrow function expression.
const addNumbers = (num1, num2) => {
return num1 + num2;
}
// Arrow function without any arguments.
const sayHello = () => console.log( 'Hello!' );
// Arrow function with a single argument.
const sayHello = name => console.log( `Hello ${name}!` );
// Arrow function with multiple arguments. (note template lateral ${}
const sayHello = (fName, lName) => console.log( `Hello ${fName} ${lName}!` );
The Template Literal, introduced in ES6, is a new way to create a string.
let name = 'Wayne';
// The old way... (you may be more familiar with concatenation)
console.log('Hello, ' + name + '!'); // Hello, Wayne!
//ES6 template literals
console.log(`Hello, ${name}!`); // Hello, Wayne!
Within template literals you can evaluate expressions.
const price = 19.99;
const tax = 0.07;
const total = `The total price is ${price + (price * tax)}`;
console.log(total);
// The total price is 21.3893
// probably should round toFixed(2) method
console.log('This is some text that flows across\two lines!');

object destructuring is a useful JavaScript feature to extract properties from objects and bind them to variables
.Let’s create some variables from the object properties.
const person = {
first: 'Wayne',
last: 'Christian',
location: {
city: 'Beverly Hills',
state: 'Florida'
}
};
const first = person.first;
const last = person.last;
Destructured
const person = {
first: 'Wayne',
last: 'Christian',
location: {
city: 'Lincoln',
county: 'Lincolnshire'
}
};
const { first, last } = person;
It even works with nested properties.
const person = {
first: 'Wayne',
last: 'Christian',
location: {
city: 'Lincoln',
county: 'Lincolnshire'
}
};
const { first, last } = person;
const { city, state } = person.location;
JavaScript is single threaded, meaning that two bits of script cannot run at the same time; they have to run one after another. Typically JavaScript is in the same queue as painting, updating styles, and handling user actions (such as highlighting text and interacting with form controls). Activity in one of these things delays the others.
A promise is an object that may produce a single value some time in the future: either a resolved value, or a reason that it’s not resolved (e.g.., a network error occurred). A promise may be in one of 3 possible states: fulfilled, rejected, or pending. Promise users can attach callbacks to handle the fulfilled value or the reason for rejection.
Promises are eager, meaning that a promise will start doing whatever task you give it as soon as the promise constructor is invoked
//fetch is promise constructor
const postsPromise = fetch('https://2018.miami.wordcamp.org/wp-json/wp/v2/posts');
postsPromise.then(data => console.log(data));
// Response {type: "cors", url: "https://2018.miami.wordcamp.org/wpjson/
wp/v2/posts", redirected: false, status: 200, ok: true, …}
const postsPromise = fetch('https://2018.miami.wordcamp.org/wp-json/wp/v2/posts');
postsPromise
.then(data => data.json())
.then(data => console.log(data))
.catch(err => console.error(err)); // in case wrong url or something
// {id: 5060, date: "2018-03-15T17:41:09", ...}
// {id: 4954, date: "2018-03-14T00:21:10", ...}
// {id: 4943, date: "2018-03-13T19:16:11", ...}
// {id: 4702, date: "2018-03-10T11:04:36", ...}

What is this?
Spread
Allows an iterable such as an array expression or string to be expanded in places
function sum(x, y, z) {
return x + y + z;
}
const numbers = [1, 2, 3];
console.log(sum(...numbers));
// expected output: 6

Over 30 UI Primitives
View
Text
ScrollView
Image
TextInput
Switch
Button
Most apps will end up using one of these basic components.
View
The most fundamental component for building a UI.
Text
A component for displaying text.
Image
A component for displaying images.
TextInput
A component for inputting text into the app via a keyboard.
ScrollView
Provides a scrolling container that can host multiple components and views.
StyleSheet
Provides an abstraction layer similar to CSS stylesheets.
These common user interface controls will render on any platform.
Button
A basic button component for handling touches that should render nicely on any platform.
Switch
Renders a boolean input.
Unlike the more generic ScrollView, the following list view components only render elements that are currently showing on the screen. This makes them a performant choice for displaying long lists of data.
FlatList A component for rendering performant scrollable lists.
SectionList
Like FlatList, but for sectioned lists.
There are also android, ios specific and utility based componants (activity monitor modal, animation etc
Mapping to Web UI primitives
View == div
Text == span / p / h*
ScrollView == div + styling
Image == img
TextInput == input
Button == button / a
Primitives are not in global scope, must be imported
// check if any node modules need installing for Cli
import { View, TouchableOpacity, StyleSheet,SafeAreaView, Button} from 'react-native';
//VS Code should import these when you use them - but check!!
Device APIs
CameraRoll
Keyboard
NetInfo
Vibration
PanResponder
Accelerometer
and many more.
Different primitives
Styling
Most browser APIs do not exist
Some browser APIs polyfilled (geolocation, fetch, timers, console)
Navigation
Mobile UI / UX
Native IDEs / configuration
Deployment
Unlike web, not every component has every interaction
Handful of “touchable” components
Button, TouchableHighlight, TouchableOpacity, TouchableWithoutFeedback
Create custom touchable components with PanResponder API Event handling ( gesture responder system)
Styling
Based on CSS styles - we have looked at "styled componants"
Layout is done with FlexBox see link
Style prop can be one or an array of styles
Use StyleSheet API for perf optimization
Makes it possible to refer to styles by ID instead of creating a new style object every time.
Allows to send the style only once through the bridge. All subsequent uses are going to refer an id (not implemented yet).
JS Objects or inline styles Styling
const styles =
{
container: {
margin: 20, backgroundColor: ‘red’
}
}
<View style={styles.container} />
Stylesheet
import { StyleSheet } from 'react-native';
const styles = StyleSheet.create(
{ container: {
margin: 20, backgroundColor: ‘red’ }
})
<View style={styles.container} />
2 Main Options
React Native CLI
Expo CLI
Expo App CLI
Builds without native projects & code
Native code not configurable
Will run without most SDKs & IDEs installed
Great for newer developers
Includes features like Camera, Location, Push Notifications, Social Authentication, Accelerometer, File System, & Image Picker configured out of the box
npm install -g expo-cli
Builds with native projects & code
Native code configurable
Needs proper environment setup in order to run
Does not include some important APIs without additional configuration
Expo Cli
1. In command line, Navigate to where you want to save your project. For example, If its on the Desktop then use cd desktop
2. Run expo init to create a project. The blank project template option will be selected by default, you can change the template with the up and down arrow keys, but let's just use the blank template for now.
Rendering logic is inherently coupled with other UI logic
It is not html in JS
it is JS in JS
const myFunction = ({name:wayne}) => {
return (
hello {name}
);
}
Return a node
Represent a piece of UI
Can be created in one of two ways:
1.Stateless (function)
2. Stateful (class)
3. React now has a functional componant (no need for classes)
React is not depricating classed but recomemnds using FC from now on
Stateless Components
Don’t need state or lifecycle methods
Any update in the props will trigger a rerender
A stateless component has no state(obvious, isn’t it?), it means that you can’t reach `this.state` inside it. It also has no lifecycle so you can’t use componentDidMount and other hooks.
import React, { Component } from "react";
class ClassComponent extends Component {
render() {
return Hello, world
;
}
}
import React from "react";
const FunctionalComponent = () => {
return Hello, world
;
};
import React, { Component } from "react";
export default class Button extends Component {
constructor() {
super();
this.state = { buttonText: "Click me, please" };
this.handleClick = this.handleClick.bind(this);
}
handleClick() {
this.setState(() => {
return { buttonText: "Thanks, been clicked!" };
});
}
render() {
const { buttonText } = this.state;
return ;
}
}
import React, { useState } from "react";
export default function Button() {
const [buttonText, setButtonText] = useState("Click me, please");
return (
);
}
3 types of component lifecycles
Creation / Mounting
Updating
Unmounting
class MyComponent extends React.Component
{
state = { name: 'Wayne’ } changeName = () => { this.setState({ name: 'Khaled' }) }
render() {
return (
Hello {this.state.name}
) }
}
Build this!

Week 2
This week, we worked with Fusion 360 and the Makerbot 3D Printers. I designed a phone case in Fusion360 based on the dimensions of my phone. My first case was too flimsy and the side wall on the right snapped off. I made my second case thicker and it's also a more snug fit.

--- creation_epoch:<PHONE_NUMBER> lastmod_epoch:<PHONE_NUMBER> categories: Security title: Installing Linux (OpenWRT) on a home router with remote VPN access --- My previous method used PPTP as a VPN server because of ease of use with Windows clients. While MSCHAPv2 with MPPE and pptp and a long password used to be sufficient it is now possible to decrypt the session with a cluster of hardware in 23 hours (you still may not get the actual password or access, but you can get a sessions content). See Microsoft says don't use PPTP and MS-CHAP
So I no longer recommend using PPTP as a VPN server. It does possibly have support for PEAP, but you must use patched versions which requires a recompile on most platforms. See http://www.nikhef.nl/~janjust/ppp/README.eap-tls
I removed my earlier directions on using PPTP with OpenWRT and now recommend you use OpenVPN instead. IPSec is another option, but only if your clients are on networks that can support tunneling it (some have NAT that do but most are flaky).

Advice from teachers and advisors is great but sometimes we need to hear the real deal. Lets face it, faculty and staff don't always know (or can't tell you) who are the best teachers and which classes are harder than others. Also when it comes to balancing school and a social life, their advice falls flat. That's where we come in! We will match you with another student with similar academic and social interests as you so that you can get the real information. Your mentor will be able to answer all those questions that teachers and advisors just can't! And upperclassman, this is your chance to pass down all that knowledge you wish you'd known!

2.16. Errors and ExceptionsSyntax errors are detected on compilation, but Python also allows for the detection of errors during program execution. When an error is detected, the Python interpreter raises (aka throws, generates, triggers) an exception. Armed with the information that Python's exception reporting can generate at runtime, programmers can quickly debug their applications as well as fine-tune their software to take a specific course of action if an anticipated error occurs. To add error detection or exception handling to your code, just "wrap" it with a TRy-except statement. The suite following the TRy statement will be the code you want to manage. The code that comes after the except will be the code that executes if the exception you are anticipating occurs: try: filename = raw_input('Enter file name: ') fobj = open(filename, 'r') for eachLine in fobj: print eachLine, fobj.close() except IOError, e: print 'file open error:', e Programmers can explicitly raise an exception with the raise command. You can learn more about exceptions as well as see a complete list of Python exceptions in Chapter 10. |

'The Blues Brothers' (1980)
A retrospective movie review by Walter Frith
Member of the 'Online Film Critics Society' http://ofcs.org/ofcs/
Dan Aykroyd's best film as a talented writer is definitely 'The Blues Brothers'. His follow-up to it in 1998 entitled 'Blues Brothers 2000' is simply horrible. Testifying further to the fact that the worse the sequel, the better the original really looks and is. Only, however, when you consider that the original people who put the first one together also made this one. 'The Blues Brothers', written by Aykroyd and the movie's director, John Landis, has so much going for it that it works for one simple reason. It achieved exactly what it was going for..... irreverence. It's the most irreverent film I've ever seen as tons of cars are destroyed, every character is so unattractive and the comedy avoids being mean spirited and comes off in a most delightfully jabbing manner. The movie is comparable to being poked in the ribs for a good laugh and it's a shame that so many of its stars are now deceased.
John Belushi (1949-1982), John Candy (1950-1994), and Cab Calloway (1907-1994) are all deceased and the second film was no fun simply because Belushi could not be in it and a film with such recognizable cult status as 'The Blues Brothers' simply cannot duplicate itself unless all of the original and important elements are intact.
Jake Blues (John Belushi) is released from prison at the beginning of the film and is picked up by his brother Elwood (Dan Aykroyd) and the two of them embark on a journey to pay a visit to a nun who was there former guardian in an orphanage where they grew up. She informs them that $5,000 is needed to save the orphanage by paying its taxes and the entire film is basically spent in the pursuit of raising the money as the Blues Brothers get into more mischief and make more enemies in comedic fashion than any other screen duo I can think of.
 Jumping over a raising bridge, nearly getting hit by ammo from a rocket launcher and having their walls come literally crashing down around them have them driving or walking away from it all in style. They really are more alike and truly act like siblings who have a lot in common.
The real payoff in the film is the last half hour as a wild car chase that lasts for 106 miles and peaks in downtown Chicago is truly a classic and one of film history's most memorable action sequences. Not entirely noticeable when you consider that thrown into the mix are persistent cops, gay nazis, country bar rednecks, jilted girlfriends and the military. The film's climax is way over the top but perfectly executed as that is exactly what was intended and credit has to be given to director John Landis as the king of irreverent comedy direction comes across masterfully in making his best film.
There are more cars destroyed in this film than any other in recent memory and even Steven Spielberg has a speaking cameo at the end of the film as a tax clerk who is the Blues Brothers last contact with civilian life before they get hauled away to.....well, see for yourself. : - )
Avoid all television broadcasts of this film if you can and the only way to truly appreciate it is on home video and DVD, and on DVD, extra lost footage has been added that gives the film a running time of nearly 2 1/2 hours. 'The Blues Brothers' is either a film you'll love or despise depending on your taste in comedy. For low brow and non-critical fans, you'll have a laugh since you don't care about much and for the more serious and high brow movie fan, the wit and self indulgent tricks in this film should be enough to give you one of the most memorable comedic rides of your life. Don't yield during this movie or you'll be frustrated.
