Woody Allen and Amazon end legal battle
Woody Allen and Amazon have ended their legal battle.
The filmmaker had sued Amazon in February after the online giant ended his 2017 contract without ever releasing a completed film A Rainy Day In New York.
Amazon had responded that Allen, whose daughter Dylan has accused him of molesting her when she was a girl, breached the four-movie deal by making insensitive remarks about the #MeToo movement.
Allen has repeatedly the allegations made by his daughter.
In papers filed on Friday in US District Court, Allen and Amazon agreed that the case should be dismissed without prejudice.
Terms were not disclosed.
A Rainy Day In New York was released overseas, but not in the US.
Allen’s career has slowed in recent years, with several actors who had appeared in his films saying they would not work with him again.

devito.symbolics package¶
Submodules¶
devito.symbolics.extended_sympy module¶
Extended SymPy hierarchy.
-
class
devito.symbolics.extended_sympy.
FrozenExpr
[source]¶ Bases:
sympy.core.expr.Expr
Use
FrozenExpr
in place ofsympy.Expr
to make sure than an expression is no longer transformable; that is, standard manipulations such as xreplace, collect, expand, … have no effect, thus building a new expression identical to self.Notes: At the moment, only xreplace is overridded (to prevent unpicking factorizations)
-
default_assumptions
= {}¶
-
xreplace
(rule)[source]¶ Replace occurrences of objects within the expression.
- rule : dict-like
- Expresses a replacement rule
xreplace : the result of the replacement
>>> from sympy import symbols, pi, exp >>> x, y, z = symbols('x y z') >>> (1 + x*y).xreplace({x: pi}) pi*y + 1 >>> (1 + x*y).xreplace({x: pi, y: 2}) 1 + 2*pi
Replacements occur only if an entire node in the expression tree is matched:
>>> (x*y + z).xreplace({x*y: pi}) z + pi >>> (x*y*z).xreplace({x*y: pi}) x*y*z >>> (2*x).xreplace({2*x: y, x: z}) y >>> (2*2*x).xreplace({2*x: y, x: z}) 4*z >>> (x + y + 2).xreplace({x + y: 2}) x + y + 2 >>> (x + 2 + exp(x + 2)).xreplace({x + 2: y}) x + exp(y) + 2
xreplace doesn’t differentiate between free and bound symbols. In the following, subs(x, y) would not change x since it is a bound symbol, but xreplace does:
>>> from sympy import Integral >>> Integral(x, (x, 1, 2*x)).xreplace({x: y}) Integral(y, (y, 1, 2*y))
Trying to replace x with an expression raises an error:
>>> Integral(x, (x, 1, 2*x)).xreplace({x: 2*y}) ValueError: Invalid limits given: ((2*y, 1, 4*y),)
- replace: replacement capable of doing wildcard-like matching,
- parsing of match, and conditional replacements
- subs: substitution of subexpressions as defined by the objects
- themselves.

IntDiv
[source]¶ Bases:
sympy.core.expr.Expr
A support type for integer division. Should only be used by the compiler for code generation purposes (i.e., not for symbolic manipulation). This works around the annoying way SymPy represents integer division, namely as a
Mul
between the numerator and the reciprocal of the denominator (e.g., ``a*3.args -> (a, 1/3)), which ends up generating “weird” C code.-

-
devito.symbolics.manipulation.
xreplace_constrained
(exprs, make, rule=None, costmodel=<function <lambda>>, repeat=False)[source]¶ Unlike
xreplace
, which replaces all objects specified in a mapper, this function replaces all objects satisfying two criteria:* The "matching rule" -- a function returning True if a node within ``expr`` satisfies a given property, and as such should be replaced; * A "cost model" -- a function triggering replacement only if a certain cost (e.g., operation count) is exceeded. This function is optional.
Note that there is not necessarily a relationship between the set of nodes for which the matching rule returns True and those nodes passing the cost model check. It might happen for example that, given the expression
a + b
, all ofa
,b
, anda + b
satisfy the matching rule, but onlya + b
satisfies the cost model.Parameters: - exprs – The target SymPy expression, or a collection of SymPy expressions.
- make – Either a mapper M: K -> V, indicating how to replace an expression in K with a symbol in V, or a function with internal state that, when called, returns unique symbols.
- rule – The matching rule (a lambda function). May be left unspecified if
make
is a mapper. - costmodel – The cost model (a lambda function, optional).
- repeat – Repeatedly apply
xreplace
until no more replacements are possible (optional, defaults to False).
-
devito.symbolics.manipulation.
xreplace_indices
(exprs, mapper, key=None, only_rhs=False)[source]¶ Replace indices in SymPy equations.
Parameters: - exprs – The target SymPy expression, or a collection of SymPy expressions.
- mapper – A dictionary containing the index substitution rules.
- key – (Optional) either an iterable or a function. In the former case,
all objects whose name does not appear in
key
are ruled out. Likewise, if a function, all objects for whichkey(obj)
gives False are ruled out. - only_rhs – (Optional) apply the substitution rules to right-hand sides only.
-
devito.symbolics.manipulation.
as_symbol
(expr)[source]¶ Extract the “main” symbol from a SymPy object.
-
devito.symbolics.manipulation.
indexify
(expr)[source]¶ Given a SymPy expression, return a new SymPy expression in which all
AbstractFunction
objects have been converted intoIndexed
objects.
devito.symbolics.queries module¶

is (separately) affine in the variablesvars
, False otherwise.Readapted from: https://stackoverflow.com/questions/36283548 /check-if-an-equation-is-linear-for-a-specific-set-of-variables/
-

Welcome to Swift!
Swift is a high-performance system programming language. It has a clean and modern syntax, offers seamless access to existing C and Objective-C code and frameworks, and is memory safe by default.
Although inspired by Objective-C and many other languages, Swift is not itself a C-derived language. As a complete and independent language, Swift packages core features like flow control, data structures, and functions, with high-level constructs like objects, protocols, closures, and generics. Swift embraces modules, eliminating the need for headers and the code duplication they entail.
Documentation
To read the documentation, start by installing the Sphinx documentation generator tool by running the command:
easy_install -U Sphinx
Once complete, you can build the Swift documentation by changing directory into
docs and typing make
. This compiles the .rst
files in the docs directory
into HTML in the docs/_build/html
directory.
Many of the docs are out of date, but you can see some historical design
documents in the docs
directory.
Another source of documentation is the standard library itself, located in
stdlib
. Much of the language is actually implemented in the library
(including Int
), and the standard library gives some examples of what can be
expressed today.
Getting Started
These instructions give the most direct path to a working Swift development environment. Options for doing things differently are discussed below.
System Requirements
macOS, Ubuntu Linux LTS, and the latest Ubuntu Linux release are the current supported host development operating systems.
For macOS, you need Xcode 8.3.2.
For Ubuntu, you'll need the following development dependencies:
sudo apt-get install git cmake ninja-build clang python uuid-dev libicu-dev icu-devtools libbsd-dev libedit-dev libxml2-dev libsqlite3-dev swig libpython-dev libncurses5-dev pkg-config libblocksruntime-dev libcurl4-openssl-dev autoconf libtool systemtap-sdt-dev tzdata
Note: LLDB currently requires at least swig-1.3.40
but will successfully build
with version 2 shipped with Ubuntu.
Build instructions for Ubuntu 14.04 LTS can be found here
Getting Sources for Swift and Related Projects
First create a directory for all of the Swift sources:
mkdir swift-source
cd swift-source
Note: This is important since update-checkout (see below) checks out repositories next to the Swift source directory. This means that if one clones Swift and has other unrelated repositories, update-checkout may not clone those repositories and will update them instead.
Via HTTPS For those checking out sources as read-only, HTTPS works best:
git clone /apple/swift.git
./swift/utils/update-checkout --clone
Via SSH For those who plan on regularly making direct commits, cloning over SSH may provide a better experience (which requires uploading SSH keys to GitHub):
git clone git@github.com:apple/swift.git
./swift/utils/update-checkout --clone-with-ssh
CMake
CMake Binary Distribution,
bundled as an application, copy it to /Applications
, and add the embedded
command line tools to your PATH
:
export PATH=/Applications/CMake.app/Contents/bin:$PATH
Ninja
Build from source
Via HTTPS
git clone /ninja-build/ninja.git && cd ninja
git checkout release
cat README
Via SSH
git clone git@github.com:ninja-build/ninja.git && cd ninja
git checkout release
cat README
Install via third-party packaging tool (macOS only)
brew install cmake ninja
The To find out more: Note: Arguments after "--" above are forwarded to A basic command to build Swift with optimizations and run basic tests with
Ninja: The Xcode IDE can be used to edit the Swift source code, but it is not currently
fully supported as a build environment for SDKs other than macOS. If you need to
work with other SDKs, you'll need to create a second build using Ninja. See docs/Testing.rst. Contributions to Swift are welcomed and encouraged! Please see the Contributing to Swift guide. To be a truly great community, Swift.org needs to welcome developers from all
walks of life, with different backgrounds, and with a wide range of experience.
A diverse and friendly community will have more great ideas, more unique
perspectives, and produce more great code. We will work diligently to make the
Swift community welcoming to everyone. To give clarity of what is expected of our members, Swift has adopted the
code of conduct defined by the Contributor Covenant. This document is used
across many open source communities, and we think it articulates our values
well. For more, see the Code of Conduct.build-script
is a high-level build automation script that supports basic
options such as building a Swift-compatible LLDB, building the Swift Package
Manager, building for iOS, running tests after builds, and more. It also
supports presets, which you can define for common combinations of build options.utils/build-script -h
build-script-impl
, which is
the ultimate shell script that invokes the actual build and test commands.utils/build-script -r -t

Everybody Pays is one of the core principles of PyCon. All attendees including speakers, chairperson, staff and volunteers have to pay for registering. While following this convention, PyCon Taiwan announced Financial Aid Program this year, which is in order to help those who really can't totally afford traffic or registration to join PyCon TW. As long as you need a financial support, please simply apply for the Financial Aid Program. All of the applications will be reviewed and determined based on the budget this year and applier's conditions by PyCon TW organizers. (Please refer to the rationale behind Everybody Pays)
Everyone is qualified to apply Financial Aid Program if you really need it and you are willing and ready to join PyCon TW and do something for communities, however, the budget is limited and so is the Financial Aid Program. That is why we wish to support people who are the most in need. For instance, taking students and engineers with full-time job into consideration, we will choose students to give aids. Then, community contributors and speakers also have higher priority for aids.

Unlimited Games. How should Red play 41?
pips Red=115 White=188
(CorrectAnswer= 0/0, ErrorScore= 0)
Many years ago, I took a series of lessons from Paul Magriel. In discussing back games he pointed out that spare checkers on top of home board points should be put to work. They add little value where they are. That applies to Red’s third checker on his 5-pt here. It is doing nothing.
White has good timing, if not ideal structure, for his 2-3 back game. Red needs to slow himself down if he can. The way to do that is to play 5/1 with the 4 in the hope of having that checker recirculated so that it can re-join the fray. The two best plays both involve 5/1, with 9/8, 5/1 being the winner.
Other plays are close but this concept or recirculating dead checkers occurs time and time again in back games, so it is important to learn the technique.

The project began with an inquiry into why people prefer not to use MUNI services, particularly during off peak hours. Numerous systemic issues like cleanliness and security emerged, but we chose to focus the project on areas particularly suited to a digital app - a lack of meaningful information and a requirement for exact change.
Provide meaningful information in a timely manner, and allow for cashless payment from the app.
Through all of the interviews I did with users of different transportation services, it became evident that people need to know exactly how long they need to wait and why. Impatience leads to abandonment. People seemed particularly pleased by the GPS vehicle tracking provided by modern car services.
Implementing GPS tracking of MUNI vehicles provides precise arrival time to stations and contextualizes any waiting time that may occur. The direct visual feedback puts users at ease and engages them in their transportation experience.
Transportation users revealed that they often go to more convenient competitors despite their higher cost, both monetarily and environmentally. Many people indicated that providing higher visibility of the impacts of their actions would go a long way in changing their habits.
While people may claim to care about their environmental impact or personal finances, they often need visual reminders to maintain good habits. Allowing users to redeem a free ride when they have offset the environmental cost of that ride provides a real world incentive for people to use the app and engage with MUNI.
Contextual inquiry of potential MUNI riders revealed that a lack of information about MUNI services, lines, and stops, combined with an unsatisfied need for guidance through the system, led to widespread abandonment in favor of more straightforward services.
By telling people step by step, from their location to their destination, exactly where they need to go and what they need to do, the app removes the intimidation of using an unfamiliar system to get around. Presenting time/cost comparisons to car services and bicycles further encourages and incentivizes people to use MUNI.
Perhaps the largest deterring factor for potential MUNI riders is the requirement to have exactly $2.25 in cash to buy a ticket. Throughout interviews and in the field, people kept expressing how much they wished they could use their phones to pay.
Allowing people to buy a 90 minute ticket for MUNI services before boarding decreases congestion at the bus entrance expediting the line, and expands ridership by allowing those without cash to participate. This could easily be integrated with existing Clipper infrastructure and allow for data analysis of ticket purchases.


The main purpose of this library is create a small and reusable serialization engine able to manage serial message protocol. The use of property decorators has allowed to reduce serialization/deserialization to a loop around properties metadata obtained at initialization time. The module has two model: one for data and another one for messages.
Data model is made to allow data (de)serialization, message module to allow to send/receive datas. Both work with buffer (byte array) and Message model is a specialization of Data model.
The main dependencie of this module is typescript compiler tsc.
npm install -g typescript
Include the lib in your project simply run:
npm install byte-serializer
After the library were added in your project, you have to import some modules dependencies:
To create a serializable payload you have to extends imported type serializable and then use decorators contained in SerializerInfo to define position, length, type and data specification of properties you have inside.
A serializable payload is just an object that can be serialized in a byte array (buffer). If you want to send, or receive, the paylod you have to add some metadatas such as start byte, expected length (or just length), id, crc and abviously data. You can choose to add a end byte to mark the end of message. For this pourpose you have to extend abstract class Message.
import {Serializable, SerializerInfo, BitOrder, NumberType, TextEncoding} from 'byte-serializer'
export class DataExample extends Serializable {
@SerializerInfo.position(0)
@SerializerInfo.length(4)
@SerializerInfo.bitOrder(BitOrder.BE)
@SerializerInfo.numberType(NumberType.Int32)
public Pippo:number;
@SerializerInfo.position(4)
@SerializerInfo.length(2)
@SerializerInfo.bitOrder(BitOrder.BE)
@SerializerInfo.numberType(NumberType.Int16)
public Pluto :number;
@SerializerInfo.position(6)
@SerializerInfo.length(10)
@SerializerInfo.textEncoding(TextEncoding.ASCII)
public Text :string;
}
Use the constructor to initialize data.
let data = new DataExample();
data.Number1 = 50;
data.Number2 = 2000;
data.Text = "A long string"; // More the 10 chars
let payload = data.serialize();
let newData = new DataExample();
newData.deserialize(payload);

Dropdowns are toggleable, contextual overlays for displaying lists of links and more. They’re made interactive with the included dropdown directives.
Wrap the dropdown’s toggle (your button or link) and the dropdown menu within dropdown
.
Dropdowns can be triggered from
or <button>
elements to better fit your potential needs.
Any single .btn
can be turned into a dropdown toggle with some markup changes.
Here’s how you can put them to work with either <button>
elements:
And with
elements:
Similarly, create split button dropdowns with virtually the same markup as single button dropdowns,
but with the addition of .dropdown-toggle-split
for proper spacing around the dropdown caret.
By default, a dropdown menu is automatically positioned 100% from the top and along the left side of its parent.
Add class .dropdown-menu-right
to a dropdownMenu
to right align the dropdown menu.
Trigger dropdown menus above elements by adding .dropup
to the parent element.
It is possible to override default dropdown config partially or completely.

Because I do per-circuit monitoring, it's not unusual for me to post long runs of 0W on a feed. The Lights circuit is a good example; unless somebody visits the basement it'll be 0W all day and only come to life in the evening. I post that to a PHPFIWA feed. I was never sure whether each zero got stored, or whether emoncms just stored the start/stop times of the long zero run. In any case, a rawdata graph of the feed used to do the right thing. I'd get a nice sharp rising edge when the first of the lights came on in the evening, and nice sharp falling edge when everyone had retired for the night. You could even see bathroom visits in the middle of the night.
As of today (maybe yesterday?) that behaviour has changed. emoncms.org seems to be doing one big diagnonal extrapolation from the first zero reading, to the first non-zero reading. I've checked the feed and can see it being refreshed wth a zero every 10 seconds as expected, so I don't think anything has changed on the sensing side.
By comparison, the pool has a similar binary ON/OFF state, but when it's off it has a few watts of background electronics running, so is never zero, and rarely the same on two consecutive posts. You can see its nice sharp edges below. That's how the light circuit used to look until today. Does anyone know if anything has changed that would explain this? And what I can do to avoid it? I guess I could add a small amount of artificial ripple in the Lights reading, but that would seem to defeat the purpose of any run detection emoncms.org might be trying to do.
Re: emoncms.org behaviour changed with runs of zeros? [SOLVED]
This is the same problem as in this thread

Re: emoncms.org behaviour changed with runs of zeros? [SOLVED]
Thanks, I'd missed that thread because I don't use multigraph. I'll continue discussions over on that thread, and have also linked it back to this one, in case anyone else has 'rawdata' issues.
Re: emoncms.org behaviour changed with runs of zeros? [SOLVED]
Thanks a lot for your help with this! replied in the multigraph thread


Dream Big
When hackers begin building something it is out of need or utility. The hacker has a problem and wants to solve it. They have done this their whole life and programming has allowed them to speed up the process. Hackers rarely think about the big picture. It is something they are taught.
Dream Big or Bootstrap
If you are looking for outside funding from venture capital, you should be thinking incredibly big. Big and Billion both begin with a 'b'. Only huge dreams get funded. If you dream too small, there is nothing for the financier to salivate about. Think about your companies current vision. I'll wait.
 The vision, unlike the product, should overlap with other startups, because it will not be a unique idea. Other people have thought, and even pitched, your vision.
The bigger and more incredible the idea, the easier it is to fund you.
Businesses Require Money to Operate
No dreamer is ever too small; no dream is ever too big.
- Anonymous
If you can bootstrap, do it! Github, Atlassian, and 37 Signals did and two of them have gone to raise some amazing first rounds. Bootstrapping is the oldest way to create a business. Find something people want. Deliver it. Get Paid. Take the Revenues, put it back into the business. Find something people want and repeat.
If you can't do that or your business requires some "tech" to build out, you have two options.
- Build it in your off-time.
- Take Financing from an external source.
Although the first is not sexy, many companies and businesses began with someone building their dream in their off-time. We are too quick to look for outside funding to build companies.
Outside funding can also be from a source that is not venture. You could get funding from a bank as a loan to start your business also. Many entrepreneurs also went into credit card debt to fund their businesses. I personally think this is a bad move, and am all about living debt free, however, it is an option.

- Robert G Allen
If you decide you want to raise capital from venture or angels, then have a huge dream. It will have to be something revolutionary, that will change the world. Anything short of this will not be good for your financing.
90% of startups fail. Which means venture capitalists need 100x returns to make 10x returns for their limited partners. This means if they give you 1mm at a 4mm valuation (20%) of your company, they want 100m back. Meaning you have to exit at 400mm.
The bigger you dream, the larger the opportunity is before you. How many lives will your startup change? Will people look back and say, I don't know how I did anything before this product.

Add JavaScript tests to <link> tags to toggle stylesheets
Similar to how you can add media queries to <link>
tags with the media=""
attribute, Slinky lets you define a custom data-selector=""
and data-test=""
attributes to any <link>
tag to define an element to watch, and a JavaScript test to evaluate from the context of the matching element.
A simple usage might toggle the display of a stylesheet when the #sidebar
element is wider than 500px:
<link
rel="stylesheet"
href="sidebar.css"
media="none"
data-selector="#sidebar"
data-test="this.offsetWidth > 500"
>
By default Slinky will add event listeners for window.load
, window.resize
, window.input
and window.click
, but you can override this by optionally specifying a data-event=""
attribute as well. This stylesheet would listen to window.scroll
alone:
<link
rel="stylesheet"
href="scroll.css"
media="none"
data-selector="body"
data-test="this.scrollTop > innerHeight"
data-event="scroll"
>
Note that in these examples I've included media="none"
so the stylesheets default to being hidden - for progressive enhancement if you wish to default to the stylesheets applying unless they need to be hidden by JS, you can leave the media="none"
off and the stylesheet will load by default, instead of remain hidden by default.

Integrating with Other Libraries
Integration with third party libraries or vanilla javascript code can be achieved via the config
attribute of virtual elements.
It's recommended that you encapsulate integration code in a component or a helper function.
The example below shows a simple component that integrates with the select2 library.
var Select2 = {
// Returns a select box
view: function(ctrl, attrs) {
var selectedId = attrs.value().id;
//Create a Select2 progrssively enhanced SELECT element
return m("select", {config: Select2.config(attrs)}, [
attrs.data.map(function(item) {
var args = {value: item.id};
// Set selected option
if(item.id == selectedId) {
args.selected = "selected";
}
return m("option", args, item.name);
})
]);
},
/**
Select2 config factory. The params in this doc refer to properties of the `ctrl` argument
@param {Object} data - the data with which to populate the <option> list
@param {prop} value - the prop of the item in `data` that we want to select
@param {function(Object id)} onchange - the event handler to call when the selection changes.
`id` is the the same as `value`
*/
// Note: The config is never run server side.
config: function(ctrl) {
return function(element, isInitialized) {
if(typeof jQuery !== 'undefined' && typeof jQuery.fn.select2 !== 'undefined') {
var el = $(element);
if (!isInitialized) {
el.select2()
.on("change", function(e) {
var id = el.select2("val");
m.startComputation();
//Set the value to the selected option
ctrl.data.map(function(d){
if(d.id == id) {
ctrl.value(d);
}
});
if (typeof ctrl.onchange == "function"){
ctrl.onchange(el.select2("val"));
}
m.endComputation();
});
}
el.val(ctrl.value().id).trigger("change");
} else {
console.warn('ERROR: You need jquery and Select2 in the page');
}
};
}
};
var Dashboard = {
controller: function() {
var ctrl = this,
//list of users to show
data = [
{id: 1, name: "John"},
{id: 2, name: "Mary"},
{id: 3, name: "Seniqua"}
];
ctrl.data = data;
// Has to use a prop for the current user
ctrl.currentUser = m.prop(data[1]);
ctrl.changeUser = function(id) {
console.log(id);
};
},
view: function(ctrl) {
return m("div", [
m("label", "User:"),
m.component(Select2, {
data: ctrl.data,
value: ctrl.currentUser,
onchange: ctrl.changeUser
})
]);
}
};
m.mount(document.body, Dashboard);
select2.config
is a factory that creates a config
function based on a given controller. We declare this outside of the select2.view
function to avoid cluttering the template.
The config
function created by our factory only runs the initialization code if it hasn't already. This if
statement is important, because this function may be called multiple times by Mithril's auto-redrawing system and we don't want to re-initialize select2 at every redraw.
The initialization code defines a change
event handler. Because this handler is not created using Mithril's templating engine (i.e. we're not defining an attribute in a virtual element), we must manually integrate it to the auto-redrawing system.
This can be done by simply calling m.startComputation
at the beginning, and m.endComputation
at the end of the function. You must add a pair of these calls for each asynchronous execution thread, unless the thread is already integrated.
For example, if you were to call a web service using m.request
, you would not need to add more calls to m.startComputation
/ m.endComputation
(you would still need the first pair in the event handler, though).
On the other hand, if you were to call a web service using jQuery, then you would be responsible for adding a m.startComputation
call before the jQuery ajax call, and for adding a m.endComputation
call at the end of the completion callback, in addition to the calls within the change
event handler. Refer to the auto-redrawing
guide for an example.
One important note about the config
method is that you should avoid calling m.redraw
, m.startComputation
and m.endComputation
in the config
function's execution thread. (An execution thread is basically any amount of code that runs before other asynchronous threads start to run.)
While Mithril technically does support this use case, relying on multiple redraw passes degrades performance and makes it possible to code yourself into an infinite execution loop situation, which is extremely difficult to debug.
The dashboard
component in the example shows how a developer would consume the select2 component.
You should always document integration components so that others can find out what attribute parameters can be used to initialize the component.
Integrating to legacy code
If you need to add separate widgets to different places on a same page, you can simply initialize each widget as you would a regular Mithril application (i.e. use m.render
, m.mount
or m.route
).
There's just one caveat: while simply initializing multiple "islands" in this fashion works, their initialization calls are not aware of each other and can cause redraws too frequently. To optimize rendering, you should add a m.startComputation
call before the first widget initialization call, and a m.endComputation
after the last widget initialization call in each execution thread.
m.startComputation()
m.mount(document.getElementById("widget1-container"), Widget1)
m.mount(document.getElementById("widget2-container"), Widget2)
m.endComputation()

England brushed aside by New Zealand in 2nd T20 as series is levelled at 1-1
England dropped FIVE catches on a ground that hasn't been kind to them over the years
by Dean Wilson, https://www.facebook.com/DeanWilsonCricketMirror/England's cricketers capped off a miserable 18 hours for national team sports after they were downed by 21 runs in Wellington.
On a ground that brings back painful World Cup 2015 memories, New Zealand were once again too hot for a lacklustre England to handle.
Their bowling was middling, their fielding was awful and their batting was about as effective as the first 20 minutes of the rugby World Cup final the night before.
It took a welcome cameo of 36 from Chris Jordan to keep England in with a shot of overhauling the Kiwi total of 176, but with wickets continuing to fall the series was levelled up at 1-1 with three left to play
As good as England and in particular James Vince was on Friday in the first game, they and he were poor here.
The Hampshire man dropped three catches of varying difficulty, two of which were simple, while Dawid Malan and Sam Billings both put down one apiece.
And then with the bat Vince arrived out in the middle with two right gloves before realising that he needed to go back and swap one over. Dozy is the only word.
Jonny Bairstow had already departed first ball of the innings when he chipped Tim Southee to mid on which was to start a trend with nine of the ten wickets falling to catches and Colin de Grandhomme taking four of them.
What should frustrate England more than anything was the way in which the batsmen kept trying to hit the ball long and straight, seemingly not appreciating that it takes 20 more metres to clear the ropes that way and the key to hitting sixes at the 'Cake Tin' is by going square.
That is what Malan did when he deposited Jimmy Neesham on the roof with the biggest hit of the lot in his 39.
The Kiwi spinners Mitchell Santner and Ish Sodhi took full advantage of the dimensions to claim five wickets between them as batsman after batsman succumbed to temptation.
Jordan revived England's hopes with his knock that included three successive sixes off Sodhi, this coming after he was the pick of the bowlers with 3-23.
Saqib Mahmood, presented with his cap by former England player and coach David Lloyd, made his international debut but found life tough to take 1-46 as too did Pat Brown with 0-32 from just two overs.
Lewis Gregory though found things a little easier as he became the ninth England player to take a wicket with his first ball, just like the man he replaced in the side Joe Denly, who did so back in 2009.

COMPONENT PROPERTY SYNTAX
Component property strings can be set in the usual way with the 'q' on a selected component instance or by menu Properties --> Edit
The dialog box allows to change the property string as well as the symbol reference. The property string is essentially a list of attribute=value items. As with symbol properties if a value has white space it should be double-quoted. The following property definitions are identical:
name=mchanged_name model=nmos w=20u l=3u m=10
name="mchanged_name" model="nmos" w="20u" l="3u" m="10"
Given the role of the " character, if quoted values are needed escapes must be used, like in the following example where the model name will be with quotes in netlist:
name="mchanged_name" model="\"nmos\"" w="20u" l="3u" m="10"
or
name="mchanged_name" model=\"nmos\" w="20u" l="3u" m="10"
the resulting SPICE netlist will be:
mchanged_name DRAIN GATE SOURCE BODY "nmos" w=20u l=3u m=10
There is no limit on the number of attribute=value items, each attribute should have a corresponding @attribute in the symbol definition format, but this is not a requirement. There are a number of special attributes as we will see later.
Important: a name=<inst_name> item is mandatory and must be placed in component property string to get a valid netlist, as this is the partname or so-called refdes (reference designator). If <inst_name> is already used in another component XSCHEM will auto-rename it to a unique name preserving the first letter (which ts a device type indicator for SPICE like netlists).
PREDEFINED COMPONENT ATTRIBUTES
- name
- embed
- url
- program
- tclcommand
- only_toplevel
- lock
- highlight
- net_name
- place
- spice_ignore
- verilog_ignore
- vhdl_ignore
- sig_type
- verilog_type
- generic_type
- class
- device_model
- pinnumber(name)
- pinnumber(index)
This defines the name of the instance. Names are unique, so if for example multiple MOS components are placed in the design one should be named m1 and the second m2 or anything else, provided the names are different. XSCHEM enforces this, unless Options -> allow duplicated instance names is set. If a name is given that already exist in the current schematic it will be renamed. Normally the template string defines a default name for a given component, and expecially for SPICE compatibility, the first character must NOT be changed. For example, the default name for a MOS transistor is m1, it can be renamed for example to mcurr_source but not for example to dcurr_source. XSCHEM does not enforce that the first character is preserved, it's up to the designer to keep it consistent with the component type.
When the embed=true is set on a component instance the corresponding symbol will be saved into the schematic (.sch) file on the next save operation. This allows to distribute schematic files that contain the used symbols so these will not depend on external library symbols. When this attribute is set on a component instance, all instances in the schematic referring to the same symbol will use the embedded symbol definition. When descending into an embedded symbol, any changes will be local, meaning that no library symbol will be affected. The changes will be saved using the embedded tag ([...]) into the schematic file. Removing this attribute will revert to external symbols after saving and reloading the schematic file.
This attribute defines a location (web page, file) that can be viewed when hitting the <shift>H key (or <Alt> left mouse buttoni) on a selected component. This is very useful to link a datasheet to a component, for example. The default program used to open the url is xdg-open. this can be changed in the ~/xschemrc configuration file with the launcher_default_program variable. url can be an http link or a local file that has a default association known to xdg-open.
this attribute can be used to specify an application to be used to open the url link, if the default application has to be changed or the file type is unknown. for example program=evince may be given to specify an application for a pdf file specified with url
this can be any tcl statement (or group of statements separated by semicolons) including all xschem-specific
commands, the statement will be executed when pressing the <shift>H key
(or <Alt> left mouse button) on the selected instance.
The tclcommand and url properties are mutually exclusive.
this attribute is valid only on netlist_commands type symbols and specifies that the symbol should be netlisted only if it is instantiated in the top-most hierarchy. This is very usefull for spice commands. Spice commands are placed in a special netlist component as we will see and are meaningfull only when simulating the block, but should be skipped if the component is simulated as part of a bigger system which has its own (at higher hierarchy level) netlistcomponent for Spice commands.
A lock=true attribute will make the symbol not editable. the only way to make it editable again is to right click on it to bring up the edit attributes dialog box and set to false. This is useful for title symbols.
If set to true the symbol will be highlighted when one of the nets attached to its pins are highlighted.
If set to true the #n:net_name symbol attributes will display the net names attached to pin terminals. the n is a pin number or name.
This place=end attribute is only valid only for netlist_commands type symbols, and tells XSCHEM that this component must be netlisted last. This is necessary for some spice commands that need to be placed after the rest of the netlist.
This tells XSCHEM that for SPICE netlist this component will be completely ignored.
This tells XSCHEM that for Verilog netlist this component will be completely ignored.
This tells XSCHEM that for VHDL netlist this component will be completely ignored.
For VHDL type netlist, this tells that the current label names a signal (or constant) of type sig_type. For example a label can be placed with name TEST and sig_type=BIT. The default type for VHDL if this property is missing is std_logic. The following picture shows the usage of sig_type and the resulting VHDL netlist. This property is applicable only to label type components: ipin.sym, iopin.sym, opin.sym, lab_pin.sym, lab_wire.sym.
This is the same as sig_type but for verilog netlisting: can be used to declare a wire or a reg or any other datatype supported by the verilog language.
generic_type defines the type of parameters passed to VHDL components. Consider the following examples of placement of generic_pin components in a VHDL design:
As you will see in the parameters slide, generics (they are just parameters passed to components) can be passed also via property strings in addition to using generic_pin components.
The class attribute is used to declare the class of a VHDL signal, most used classes are signal and constant. Default if missing is signal.
This attribute contains a SPICE .model or .subckt specification (device_model=".model D1N4148 D ....") that will be printed at end of netlist only once for the specified component (D1N4148 in the example). device_model attributes defined at instance level override the device_model set in the symbol if any.
This will override at instance level the value of attribute pinnumber of pin name of the symbol. This is mainly used for tedax, where by back annotation a connection to a symbol must be changed.
This will override at instance level the value of attribute pinnumber of indexth pin of the symbol. This is mainly used for tedax, where by back annotation a connection to a symbol must be changed. This notation is faster since xschem does not have to find a pin by string matching.


Creation of module requires package.json to be generated. Let's generate package.json using npm, which will generate basic skeleton of the package.json.
$ npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sane defaults.
See 'npm help json' for definitive documentation on these fields
and exactly what they do.
Use 'npm install --save' afterwards to install a package and
save it as a dependency in the package.json file.
Press ^C at any time to quit.
name: (webmaster)
You will need to provide all the required information about your module. YOu can take help from the above mentioned package.json file to understand the meanings of various information demanded. Once package.json is generated. Use the following command to register yourself with npm repository site using a valid email address.
$ npm adduser
Username: mcmohd
Password:
Email: (this IS public<EMAIL_ADDRESS>Now its time to publish your module:
$ npm publish
If everything is fine with your module, then it will be published in the reporsitory and will be accessible to install using npm like any other other Node.js module.

# ![Bivariate](bivariate.png)
***An opinionated interface for writing, running, and saving BackstopJS tests***
## Goal
**Bivariate**'s goal is to allow for an approachable Visual Regression Testing suite that can be organized to accommodate small and large projects without overwhelming complexity.
![Bivariate App](./documentation/menu.gif)
This goal is achieved by enforcing an opinionated grouping structure, providing a method to easily write tests via manageable object files, as well as allowing for all of BackstopJS's commands to be run from an interface.
## Installation
**Bivariate** runs in [Node](https://nodejs.org).
* Install [NodeJS](https://nodejs.org)
* Install the Latest version of Bivariate via NPM.
It is *recommended* to install Bivariate *globally*, but it can run locally if required:
global install (*recommended*):
`npm install bivariate -g`
local install:
`npm install bivariate`
* Ensure you have version 59 or greater of [Chrome](https://www.google.com/chrome/browser/) installed.
Bivariate utilizes headless Chrome which started shipping in Chrome v59
* From your project directory, run Bivariate:
if installed globally:
`bivariate`
if only installed locally:
`npx bivariate`
* Generate `bivariate_data`:
If Bivariate doesn't detect any existing Bivarte tests it will ask you would like to generate the starting configuration files.
![Bivariate App](./documentation/first-run.gif)
## Folder Structure
*All tests, scripts, and configuration files are stored in the `bivariate_data` parent folder.*
`bivariate_data`
|
+---- `test_scripts` holds user defined configuration and tests used to instruct BackstopJS
|
+---- `engine_scripts` holds user defined Puppeteer scripts for interacting with the Chrome DOM before saving a screen shot
|
+---- `bitmaps_reference_archive` holds archived *references* that can be restored and tested against
### test_scripts
Out of the box, BackstopJS gets all of its config and test data from a single JSON file, which isn't very maintainable over time. Luckily, **Bivariate** takes advantage of Node's module system to break this all apart and just return what is needed (*a simple array of objects*).
#### Configuration files
All configuration files are prefixed with a double underscore: \_\_
##### \_\_config-baseURLs.js
holds the *base* URLs for all References and Tests to be run.
```js
...
// do not use a trailing slash in the base URLs
theURLS.baseURL = "http://your-base-url";
theURLS.baseRefURL = "http://your-base-reference-url";
...
```
##### \_\_config-common.js
set of *common* config values (rendering engine, ports, etc.) that shouldn't need to be adjusted in most cases.
##### \_\_config-viewports.js
configure any number of *viewports* to test against (this can include any number of defined screen resolutions).
#### Individual Tests
All individual tests are prefixed with a single underscore: \_
Use the example tests as a template to create your own. Tests are easy to setup and for the most part only require you to fill out the value for a few variables:
* label
* route
* selectors
`_example-test--home.js` :
````js
// -------------------
// - test definition -
// -------------------
// * tests should be saved as: '_test-name.js'
// if you have a lot of tests you can store
// related tests in named subdirectories
// for better organization
var label = "Example Test - Home Page"
var route = "/index.html"
var readySelector = ""
var hideSelectors = []
var removeSelectors = []
var selectors = [ "document", "h1", ".hero", ".nav", ".body-content" ]
let hoverSelector = null
let hoverSelectors = []

#### Test Groups
Bivariate presents and runs tests using a grouping concept.  A test group is a .js file that does not start with any underscores.
Use the provide file `example-test-group.js` as a template for your own. Note that all that is required is to fill in the `Scenarios` section to include which tests you want run.
`example-test-group.js` :
````js
// ----------------
// -- Test Group --
// ----------------
let mixIn = require("./../libs/mout-mixin/mixIn");
let testGroup = __filename.slice(__dirname.length + 1, -3);
let configCommon = require('./__config-common')(testGroup);
let baseURLs = require("./__config-baseURLs");
module.exports = mixIn(
{
// ---------------
// -- Scenarios --
// ---------------
"scenarios": [
require('./_example-site--home')(baseURLs),
require('./_example-site--paints')(baseURLs)
],
},
configCommon
);
````
### engine_scripts
engine scripts are used to interact with your web pages using the `before` and `on ready` events. Each test you create has an optional parameter of `onBeforeScript` & `onReadyScript`. These can simply point to script files in the 'engine_scripts' directory. The two example scripts found in the `engine_scripts` directory should be self explanatory (`onBefore-Example.js` & `onReady-Example.js`). In addition you can refer to the [Puppeteer Docs](https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md) for more advanced examples.
### bitmaps_reference_archive
The `bitmaps_reference_archive` folder holds archived `references` which can be created, archived, and restored using the **Bivariate** app.
----
## App
Example run of the test scripts generated by Bivariate:
![Bivariate App Example Run](./documentation/example-run.gif)
For more info, reference `example-site` README for a walk through example of **Bivariate** in action.
### [Example Site Docs](./example-site/README.md)
Detailed docs for what the `reference`, `test`, and `approve` commands do under the hood can be found on the BackstopJS Github page: [BackstopJS](https://github.com/garris/BackstopJS).


Kevin Kelly went to Myanmar and took these incredible photos
by Mark FrauenfelderWhen my friend and Cool Tools partner Kevin Kelly showed me these photos he recently took in Myanmar, I told him that it seems like he has a time machine. And he said, " I do call it a time machine."
