On mobile devices, using on-click
isn't good enough. Tapping the touchscreen will fire a simulated click event, but only after a 300 millisecond delay, which makes your app feel sluggish. It also causes the tapped area to highlight, which in most cases looks a bit messy.
Instead, use on-tap
. When you tap an area, the simulated click event will be prevented, and the user's action is responded to instantly. The on-tap
event also differs from on-click
in that the click event will (frankly rather bizarrely) fire even if you hold the mouse down over a single element for several seconds and waggle it about.
Pointer events are also supported, as is pressing the spacebar when the relevant element is focused (which triggers a click event, and is good for accessibility).

Notes about asynchronous JavaScript
I work with async JavaScript a lot, but I wonder if I know everything about it that I need to.
I’m working through my Udemy course again (“The Complete JavaScript Course 2023: From Zero to Expert”) and will share some notes below.
AJAX and XML
AJAX: Asynchronous JavaScript and XML
- MDN page
- make requests to servers and updates to the UI without having to refresh the page
The old way: XML. We used to use XML, but JSON is now most common. It’s easier to use JSON data in JavaScript code, plus it’s smaller in size than XML.
- you can get any type of data, not just XML - MDN
How that works:
const request = new XMLHttpRequest();
request.open("GET", url); //whatever url you are fetching from
request.send();
//use callback function to do something once we get the data
request.addEventListener("load", function () {
const data = JSON.parse(this.repsonseText);
});
Promises
The above code works fine when you only need to make one request. However, what if you need to make multiple requests? What if they need to be made in a particular order, or subsequent requests rely on earlier ones? In this situation you end up with callbacks inside of callbacks inside of callbacks - callback hell. The code becomes unmanagable at this point.
Since ES6 you can avoid this by using promises:
//no need for event listeners or callbacks
const request = fetch(url); //whatever url you are fetching from
This code returns a promise. Promises are used as placeholders for the result of the async request. The fetch API used above builds (creates) the promise for us to consume.
Promise lifecycle/states:
- pending: waiting for the value to be returned
- settled: async task finished
- fulfilled: a value was returned to us
- rejected: some error happened
We can more easily chain promises using the ES6 .then
method.
To handle errors/rejected promises, we use the .catch
method. It will catch errors that occur anywhere in the .then
promise chain.
There is also a .finally
method, that is run no matter what happens with the promise.
//when the promise is settled, use .then and .catch
const request = fetch(url)
.then((response) => {
//need to parse the data
//this is also a promise, so we need another .then
return response.json();
})
.then((data) => {
//do something with the data
})
.catch((err) => {
//do something with the error
})
.finally(() => {
//do something no matter what
});
You can also handle specific errors with:
throw New Error()
.catch
method will catch these errors too.
The event loop
How does the JavaScript runtime work?
- JS engine includes the heap (where things are stored in memory) and the call stack (where the code is executed)
- JS is single threaded - meaning it handles one operation at a time. JavaScript doesn’t multitask.
- runtime also includes various web APIs, like DOM, fetch, event, geolocation, etc. These are not a part of the language, just provided to the JS engine to use
- Callback queue: a data structure that holds callback functions that are attached to events. When the call stack is empty, the event loop takes callbacks from the queue and adds them to the call stack.
- when an event is emitted, it is placed in the callback queue
- the first item in the queue is taken by the event loop and placed on the call stack
- this is how we can have asynchronous behavior in JavaScript
- Microtasks queue: for promises. Acts similarly to callback queue, but actually has priority over it.
Concurrency model: how JS handles multiple tasks in a non-blocking (not waiting for other operations to finish running) way. The question is, how can this actually happen if the language is single threaded?
Some async tasks run in the Web APIs environment, not on the call stack. For example, loading an image, fetching data, etc. So it’s not happening on our thread of execution.
Creating a promise
Use the promise constructor. It takes in an executor function with two parameters: resolve and reject.
const myPromise = new Promise(function (resolve, reject) {
if (Math.random() > 0.5) {
resolve("You win!");
} else {
reject("You lose!");
}
});
myPromise.then((res) => console.log(res)).catch((err) => console.log(err));
Promisifying: to convert callback behavior into promise behavior. We can then consume the promise like above instead of using callbacks.
Async/await
Place async
in front of function keyword. The function will return a promise. await
statements are placed inside the function.
await
stops code execution and waits until the promise is returned. But, because of the async
keyword, this is happening inside an asynchronous function, and this execution is happening in the background. The call stack is not being blocked while waiting for this promise. Everything is happening behind the scenes, it’s just this syntax makes it look synchronous. Promises are still being used.
Now you can assign resolved values from promises to variables, like we’ll see below.
const myFetchFunction = async function () {
//below, res is the resolved value of the promise
const res = await fetch(`https://mylink.com`);
const data = await res.json();
return data;
};
const data = await myFetchFunction();
await
keyword can currently only be used inside of async functions. You could wrap your code inside of an IIFE to get around this if needed.
Try/catch
Use try/catch blocks for error handling. This is comparable to the .then
and .catch
syntax, but when we use async/await, there is nothing to chain the .catch
onto.
Wrap your code in a try block. If an error occurs in the try block, the catch block code is executed.
const myFetchFunction = async function () {
try {
const res = await fetch(`https://mylink.com`);
//error gets caught in the catch block
if (!res) throw new Error("Problem getting data");
const data = await res.json();
return data;
} catch (e) {
return e;
}
};
const data = await myFetchFunction();
Awaiting multiple promises at once
What do you do when you are waiting for several promises at once, but you don’t need them to arrive in order? If you are making several requests, one after the other in your code, they will be fetched one after the other.
You can use Promise.all()
to make sure they’re fetched concurrently. Place all your promises in an array:
const data = await Promise.all([
getJSON(`https://mylink.com/1`),
getJSON(`https://mylink.com/2`),
getJSON(`https://mylink.com/3`),
]);
Now, these requests will be running at the same time, instead of synchronously.
The only problem is if one fails, the whole operation fails.
Some other options
Promise.race()
: resolved when the first one is resolved
Promise.allSettled()
: you get the results of all promises, even if they are rejected
Promise.any()
: similar to Promise.race, but ignores promises that reject


When you finish writing all the chapters and after adding them to the config.yml
archive, run the following command to publish the book (replace the-origin-of-the-species
by the name of your book directory):
$ ./book publish 'the-origin-of-species' web
If everything works fine, you should see a new web
directory inside Output/
directory. Enter the web/
directory and you'll find a file named book.html
. This is the complete book in HTML format, ready to publish it on the Internet.
Then, run the following command:
$ ./book publish 'the-origin-of-species' website
Now, inside Output/
directory you'll find a new website
directory with several HTML pages. Open index.html
in your browser and you'll see that easybook has published your book as a fully-functional static website.
Lastly, run the following command:
$ ./book publish 'the-origin-of-species' print
Inside Output/
directory you'll find a new print
directory which contains a file name book.pdf
. Open the file with your PDF reader and you'll see your book as a beautiful and carefully created PDF ebook. The PDF conversion is made with an external application named PrinceXML. If you don't have it installed on your computer, you can download a fully-functional demo version at http://www.princexml.com/download/
easybook lets you easily publish the same book in very different ways. Each of these ways is called edition. This concept will be explained in the next chapter.

Advantage of Virsion Control
How does Git Help Me?
22nd March 2015
It's been 1 month since you have started your first job after collage.  What should you do? Could you have prevented it? Most would think that this would situation would not happen to them, but its common that you would think. If you were using Version Control, you could just go and retrieve it.
Most of us who have used any type of text editor like Microsoft Word or played a video game where after failing a level go back to a checkpoint have used some type of version control. When you accidentally remove a paragraph and click undo, you are using a form of version control. Any program that remembers what you have changed and lets you go back to some previous state is using version control.
One option of version control is a tool called Git which can be installed on your own computer. This tool lets you save your progress as you work and keeps track of your project every time you same. So if you happen to start working on modifying a part of code and did not like where it was going, you would be able to use git and revert your changes.
Now most people in the Tech industry work on very large programs that contain thousands of lines of code. The usually work on teams where multiple people need to access the same part of the code at the same time. Just imagine trying to change a copy of your code and then having to go back and compare with other who have made changes to the same file. This would be a nightmare for anyone developer. With the help of GitHub, your team can have a one main version of working code that is always evolving. GitHub lets uses create a tree structure where the main (root) code can be copied multiple times (like branches of trees) and then when its working can be merged back to main code. With the use of GitHub you have advantage of having multiple versions of code with the ability to choose which version you want to go with.


JavaBeans are the way to use Java objects from JSP pages in order to
follow the MVC design pattern. The point of doing this is to implement
something similar to the Pull
methodology. For example:
|
|
|
|
<jsp:useBean id="name" scope="page|request|session|application"
class="className" type="typeName">
|
|
|
|
|
Examining the syntax of the above code, the first thing that pops up
right away is the use of the scope attribute. How many HTML designers
understand the programming concepts of scope? It is safe to suggest that
a good portion of web designers barely understand the concept of how a
CGI works. By stating this, we are not trying to slight people. Instead,
we are simply pointing out that design and software engineering are
distinct skill sets. You wouldn't expect a Java programmer to select a
print and web safe color palette, would you?
The common response to an argument like this is that the designers
should simply ignore these tags and let others define and implement
them. The problem with that is that you have now given them the power to
accidentally wreck your entire application in such a way that it is
very difficult to debug because a complex scope issue might not show up
right away.

The Java code:
public class HelloBean {
private String name = "World";
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
}
The JSP code:
<jsp:useBean id="hello" class="HelloBean">
<jsp:setProperty name="hello" property="*" />
</jsp:useBean>

<TITLE>Hello</TITLE>

Hello, <jsp:getProperty name="hello" property="name" />

|
|
|
|
|
Above, we have a very simple example of using a bean in a page. Pass it
some properties and then retrieve the results. This is the right way to
do things when using JSP. However, if we look at an example of doing the
same exact thing in Velocity, the extra amount of needless typing that
one needs to perform to simply retrieve a property seems a just bit
absurd. Of course there are always GUI based drag and drop tools to make
typing a thing of the past. Really.
There are several commercial solutions available today which provide a
nice drag and drop view for doing development with JSP and Struts.
However many of these tools are still first generational tools. They
typicially only address parts of the problem and require digging down
into the nitty gritty stuff when things become difficult or even
impossible to do with the GUI (anyone remember a product called Tango?).
Often these tools also produce code that is not optimized for heavily
hit sites and getting an existing application to scale sometimes
requires a complete rewrite. Again, this is not our decision, it is
yours. Another item to note here is that these are costly (>$1000/seat)
development tools. In this .bomb economy, who really has the money to
spend on these tools?
|
|
|
|
The Java code:
context.put ("hello", new HelloBean());
The Velocity code:
$hello.setName("*")

<TITLE>Hello</TITLE>

Hello, $hello.Name

|
|
|
|
|
The example shows the creation of the HelloBean() object and then
placing it into the Context. Then, during runtime execution of the
template, that object is available as a $variable which uses the
JavaBean specification to do introspection on the object. For example,
Velocity uses Bean style introspection to permit the method call to be
shortened from $hello.getName()
to simply typing what is
shown above.
When Velocity is combined with Turbine, the HelloBean object can be
added into the Context as a configuration option or it can be added at
any point of the processing. This is what provides the "scope" of the
object in the Context.
Another "gotcha" with using JavaBeans in JSP is again quoted from Jason's
book:
|
|
|
|
One thing to watch out for: On some servers (including Tomcat 3.2) if
you have a bean with a scope of "session" or "application" and you
change the bean class implementation, you may get a ClassCastException
on a later request. This exception occurs because the generated servlet
code has to do a cast on the bean instance as it's retrieved from the
session or application, and the old bean type stored in the session or
application doesn't match the new bean type expected. The simplest
solution is to restart the server.
|

|
|
You make the decision.

--- layout: post title: "Either bifunctor" description: "Either forms a bifunctor. An article for object-oriented programmers." date: 2019-01-07 9:13 UTC tags: [Software Design] --- {% include JB/setup %}
{{ page.description }}
This article is an instalment in an article series about bifunctors. As the overview article explains, essentially there's two practically useful bifunctors: pairs and Either. In the previous article, you saw how a pair (a two-tuple) forms a bifunctor. In this article, you'll see how Either also forms a bifunctor.
In the previous article, you saw how, if you have maps over both dimensions, you can trivially implement SelectBoth
(what Haskell calls bimap
):
return source.SelectFirst(selector1).SelectSecond(selector2);
The relationship can, however, go both ways. If you implement SelectBoth
, you can derive SelectFirst
and SelectSecond
from it. In this article, you'll see how to do that for Either.
Given the Church-encoded Either, the implementation of SelectBoth
can be achieved in a single expression:
public static IEither<L1, R1> SelectBoth<L, L1, R, R1>( this IEither<L, R> source, Func<L, L1> selectLeft, Func<R, R1> selectRight) { return source.Match<IEither<L1, R1>>( onLeft: l => new Left<L1, R1>( selectLeft(l)), onRight: r => new Right<L1, R1>(selectRight(r))); }
Given that the input source
is an IEither<L, R>
object, there's isn't much you can do. That interface only defines a single member, Match
, so that's the only method you can call. When you do that, you have to supply the two arguments onLeft
and onRight
.
The Match
method is defined like this:
T Match<T>(Func<L, T> onLeft, Func<R, T> onRight)
Given the desired return type of SelectBoth
, you know that T
should be IEither<L1, R1>
. This means, then, that for onLeft
, you must supply a function of the type Func<L, IEither<L1, R1>>
. Since a functor is a structure-preserving map, you should translate a left case to a left case, and a right case to a right case. This implies that the concrete return type that matches IEither<L1, R1>
for the onLeft
argument is Left<L1, R1>
.
When you write the function with the type Func<L, IEither<L1, R1>>
as a lambda expression, the input argument l
has the type L
. In order to create a new Left<L1, R1>
, however, you need an L1
object. How do you produce an L1
object from an L
object? You call selectLeft
with l
, because selectLeft
is a function of the type Func<L, L1>
.
You can apply the same line of reasoning to the onRight
argument. Write a lambda expression that takes an R
object r
as input, call selectRight
to turn that into an R1
object, and return it wrapped in a new Right<L1, R1>
object.
This works as expected:
> new Left<string, int>("foo").SelectBoth(string.IsNullOrWhiteSpace, i => new DateTime(i)) Left<bool, DateTime>(false) > new Right<string, int>(1337).SelectBoth(string.IsNullOrWhiteSpace, i => new DateTime(i)) Right<bool, DateTime>([01.01.0001 00:00:00])
Notice that both of the above statements evaluated in C# Interactive use the same projections as input to SelectBoth
. Clearly, though, because the inputs are first a Left
value, and secondly a Right
value, the outputs differ.
When you have SelectBoth
, you can trivially implement the translations for each dimension in isolation. In the previous article, I called these methods SelectFirst
and SelectSecond
. In this article, I've chosen to instead name them SelectLeft
and SelectRight
, but they still corresponds to Haskell's first
and second
Bifunctor
functions.
public static IEither<L1, R> SelectLeft<L, L1, R>(this IEither<L, R> source, Func<L, L1> selector) { return source.SelectBoth(selector, r => r); }
The method body is literally a one-liner. Just call SelectBoth
with selector
as the projection for the left side, and the identity function as the projection for the right side. This ensures that if the actual value is a Right<L, R>
object, nothing's going to happen. Only if the input is a Left<L, R>
object will the projection run:
> new Left<string, int>("").SelectLeft(string.IsNullOrWhiteSpace) Left<bool, int>(true) > new Left<string, int>("bar").SelectLeft(string.IsNullOrWhiteSpace) Left<bool, int>(false) > new Right<string, int>(42).SelectLeft(string.IsNullOrWhiteSpace) Right<bool, int>(42)
In the above C# Interactive session, you can see how projecting three different objects using string.IsNullOrWhiteSpace
works. When the Left
object indeed does contain an empty string, the result is a Left
value containing true
. When the object contains "bar"
, however, it contains false
. Furthermore, when the object is a Right
value, the mapping has no effect.
Similar to SelectLeft
, you can also trivially implement SelectRight
:
public static IEither<L, R1> SelectRight<L, R, R1>(this IEither<L, R> source, Func<R, R1> selector) { return source.SelectBoth(l => l, selector); }
This is another one-liner calling SelectBoth
, with the difference that the identity function l => l
is passed as the first argument, instead of as the last. This ensures that only Right
values are mapped:
> new Left<string, int>("baz").SelectRight(i => new DateTime(i)) Left<string, DateTime>("baz") > new Right<string, int>(1_234_567_890).SelectRight(i => new DateTime(i)) Right<string, DateTime>([01.01.0001 00:02:03])
In the above examples, Right
integers are projected into DateTime
values, whereas Left
strings stay strings.
Either obeys all the bifunctor laws. While it's formal work to prove that this is the case, you can get an intuition for it via examples. Often, I use a property-based testing library like FsCheck or Hedgehog to demonstrate (not prove) that laws hold, but in this article, I'll keep it simple and only cover each law with a parametrised test.
private static T Id<T>(T x) => x; public static IEnumerable<object[]> BifunctorLawsData { get { yield return new[] { new Left<string, int>("foo") }; yield return new[] { new Left<string, int>("bar") }; yield return new[] { new Left<string, int>("baz") }; yield return new[] { new Right<string, int>( 42) }; yield return new[] { new Right<string, int>( 1337) }; yield return new[] { new Right<string, int>( 0) }; } } [Theory, MemberData(nameof(BifunctorLawsData))] public void SelectLeftObeysFirstFunctorLaw(IEither<string, int> e) { Assert.Equal(e, e.SelectLeft(Id)); }
This test uses xUnit.net's [Theory]
feature to supply a small set of example input values. The input values are defined by the BifunctorLawsData
property, since I'll reuse the same values for all the bifunctor law demonstration tests.
The tests also use the identity function implemented as a private
function called Id
, since C# doesn't come equipped with such a function in the Base Class Library.
For all the IEither<string, int>
objects e
, the test simply verifies that the original Either e
is equal to the Either projected over the first axis with the Id
function.
Likewise, the first functor law applies when translating over the second dimension:
[Theory, MemberData(nameof(BifunctorLawsData))] public void SelectRightObeysFirstFunctorLaw(IEither<string, int> e) { Assert.Equal(e, e.SelectRight(Id)); }
This is the same test as the previous test, with the only exception that it calls SelectRight
instead of SelectLeft
.
Both SelectLeft
and SelectRight
are implemented by SelectBoth
, so the real test is whether this method obeys the identity law:
[Theory, MemberData(nameof(BifunctorLawsData))] public void SelectBothObeysIdentityLaw(IEither<string, int> e) { Assert.Equal(e, e.SelectBoth(Id, Id)); }
Projecting over both dimensions with the identity function does, indeed, return an object equal to the input object.
In general, it shouldn't matter whether you map with SelectBoth
or a combination of SelectLeft
and SelectRight
:
[Theory, MemberData(nameof(BifunctorLawsData))] public void ConsistencyLawHolds(IEither<string, int> e) { bool f(string s) => string.IsNullOrWhiteSpace(s); DateTime g(int i) => new DateTime(i); Assert.Equal(e.SelectBoth(f, g), e.SelectRight(g).SelectLeft(f)); Assert.Equal( e.SelectLeft(f).SelectRight(g), e.SelectRight(g).SelectLeft(f)); }
This example creates two local functions f
and g
. The first function, f
, just delegates to string.IsNullOrWhiteSpace
, although I want to stress that this is just an example. The law should hold for any two (pure) functions. The second function, g
, creates a new DateTime
object from an integer, using one of the DateTime
constructor overloads.
The test then verifies that you get the same result from calling SelectBoth
as when you call SelectLeft
followed by SelectRight
, or the other way around.
The composition laws insist that you can compose functions, or translations, and that again, the choice to do one or the other doesn't matter. Along each of the axes, it's just the second functor law applied. This parametrised test demonstrates that the law holds for SelectLeft
:
[Theory, MemberData(nameof(BifunctorLawsData))] public void SecondFunctorLawHoldsForSelectLeft(IEither<string, int> e) { bool f(int x) => x % 2 == 0; int g(string s) => s.Length; Assert.Equal(e.SelectLeft(x => f(g(x))), e.SelectLeft(g).SelectLeft(f)); }
Here, f
is the even function, whereas g
is a local function that returns the length of a string. The second functor law states that mapping f(g(x))
in a single step is equivalent to first mapping over g
and then map the result of that using f
.
The same law applies if you fix the first dimension and translate over the second:
[Theory, MemberData(nameof(BifunctorLawsData))] public void SecondFunctorLawHoldsForSelectRight(IEither<string, int> e) { char f(bool b) => b ? 'T' : 'F'; bool g(int i) => i % 2 == 0; Assert.Equal(e.SelectRight(x => f(g(x))), e.SelectRight(g).SelectRight(f)); }
Here, f
is a local function that returns 'T'
for true
and 'F'
for false
, and g
is a local function that, as you've seen before, determines whether a number is even. Again, the test demonstrates that the output is the same whether you map over an intermediary step, or whether you map using only a single step.
This generalises to the composition law for SelectBoth
:
[Theory, MemberData(nameof(BifunctorLawsData))] public void SelectBothCompositionLawHolds(IEither<string, int> e) { bool f(int x) => x % 2 == 0; int g(string s) => s.Length; char h(bool b) => b ? 'T' : 'F'; bool i(int x) => x % 2 == 0; Assert.Equal( e.SelectBoth(x => f(g(x)), y => h(i(y))), e.SelectBoth(g, i).SelectBoth(f, h)); }
Again, whether you translate in one or two steps shouldn't affect the outcome.
As all of these tests demonstrate, the bifunctor laws hold for Either. The tests only showcase six examples for either a string or an integer, but I hope it gives you an intuition how any Either object is a bifunctor. After all, the SelectLeft
, SelectRight
, and SelectBoth
methods are all generic, and they behave the same for all generic type arguments.
Either objects are bifunctors. You can translate the first and second dimension of an Either object independently of each other, and the bifunctor laws hold for any pure translation, no matter how you compose the projections.
As always, there can be performance differences between the various compositions, but the outputs will be the same regardless of composition.
A functor, and by extension, a bifunctor, is a structure-preserving map. This means that any projection preserves the structure of the underlying container. For Either objects, it means that left objects remain left objects, and right objects remain right objects, even if the contained values change. Either is characterised by containing exactly one value, but it can be either a left value or a right value. No matter how you translate it, it still contains only a single value - left or right.
The other common bifunctor, pair, is complementary. Not only does it also have two dimensions, but a pair always contains both values at once.

A$AP Mob announce Yams Day 2020
by Andrew SacherA$AP Mob‘s annual Yams Day — their big annual, guest-filled NYC concert that happens in honor of the late A$AP Yams — returns in 2020 on January 17 at Barclays Center. Tickets go on sale Friday (11/15) at 10 AM with artist, official platinum, and VIP presales starting today (1/13) at 1 PM. Presale password = YAMMYGANG. A portion of the proceeds goes to the Always Strive and Prosper Foundation, which was established by Yams’ mom and is “dedicated to fostering greater awareness of drug and substance abuse, as well as providing support for alternatives promoting prevention and education.”
As usual, the guests aren’t announced yet, but they’re usually pretty great. Last year had Soulja Boy, Meek Mill, Flatbush Zombies, Young M.A, Joey Bada$$, and more.


A new programming language called Swift was announced at WWDC'14. Here's a source-to-source comparison of Swift and C# using the examples given in "The Swift Programming Language" book published by Apple in the iTunes Store.
Jacob Leverich provides another excellent point-by-point comparison with Scala.

THE FRIGHTENERS A film review by Michael John Legeros Copyright 1996 Michael John Legeros
(Universal) Directed by Peter Jackson Written by Peter Jackson and Frances Walsh Cast Michael J. Fox, Trini Alvarado, Peter Dobson, Jeffrey Combs, Dee Wallace-Stone, Jake Busey, Jim Fyfe, Chi McBride, John Astin MPAA Rating "R" (presumably for gore and profanity) Running Time 106 minutes Reviewed at General Cinemas at Pleasant Valley, Raleigh, NC (16JUL96)
==
Each week, the magazine "Entertainment Weekly" includes a blurb in their movie section which compares the opinions of several national critics. Their ratings are averaged and compared to the weekly results of an audience exit poll. Not surprisingly, the public tends thinks more of most movies than the critics do. One of the explanations for this might involve the concept of popular versus critical opinion. I won't go down *that* road. Another likely reason is the simple fact that most people want to enjoy what they pay for, even if they don't really like it. Think about that. Add in the price of popcorn, plus the investment of time required to wait in traffic, wait in the lobby, and wait for the trailers to end, and you're stuck in a situation where the only alternative to feeling good about a movie, is to feel shame for the wasted effort. For this reason, I presume that most folks will *not* be walking out of THE FRIGHTENERS, a failed supernatural comedy that is nearly unwatchable for the first thirty minutes.
The beginning is the worst-- a sloppy, incoherent mess that shows such silliness as a woman (Dee Wallace Stone) being chased through an old mansion by special-effects induced apparitions, a short "psychic investigator" (Michael J. Fox) attempting to crash a funeral, and that same person later careening down a hill in an out-of-control jalopy. Huh? Is bad driving what New Zealand director Peter Jackson (HEAVENLY CREATURES) thinks is funny to us Americans? Next comes the appearance of a floating Elvis statue-- "he lives," utters an unbeliever-- and the discovery that Fox's character is a con man, thankyouverymuch. Though he really *can* see the spooks, he's actually on fairly friendly terms with them. They help him scare up business. Of course, nobody in the small coastal town is particularly fazed by these ghoulish goings-on. Maybe they've seen GHOSTBUSTERS a few too many times, but the residents sure take their psychic investigator in stride. Just as they seem unfazed by a recent rash of inexplicable deaths...
Mercifully, the movie gets (a bit) better as it goes. The human element is execrable, but a clever cast of Caspers often amuses. Chi McBride is funny as a jive-talking spirit still wearing bell- bottoms. That's John Astin under make-up as the (literally) jaw- dropping Judge; he has some salacious fun with an Egyptian mummy. Also look for a memorable appearance by R. Lee Ermey, reprising his FULL METAL JACKET role as a deceased drill instructor. I rather enjoyed all the oppressive imagery of death and decay. You may want to leave the younger ones at home, though, as the rotting corpses and dusty skeletons may send them screaming into the lobby. Heh, heh. A macabre finale, set inside of an abandoned hospital, is the high-point of this low movie. Jackson cross-cuts between the present (Fox and Trini Alvarado in peril) and the past (Jake Busey as a mass-murdering orderly) and it's a grisly gas. With exploding heads and carved foreheads, the sequence might even have been scary, if the rest of the movie hadn't so completely dulled our senses.
Grade: C+

Suppose you need two classes, Class1 and Class2. You would then create two paramdef files, say paramdef.Class1 and paramdef.Class2. The Makefile can easily be set up to generate two code classes.
The following files would be generated:
Class1.hh Class1.cc Class2.hh Class2.ccEach class has its own user interface. Instead of using _tdrp_load_from_args(), you would use the functions:
Class1::load() Class2::load()to load up the parameters for each class.
Since the load() functions operate at a lower level than _load_from_args(), you will need to write code to parse the command line and respond to any TDRP arguments.

About this tool
This is a
set of open-source tools
to daily
collect and serve consolidated taxonomic and occurrence data
from various open data sources
, perform geospatial analysis
that enable rapid risk assessment
of country-level biodiversity
, and allow simple and directed visualization
of the data and results.
How does this work
Specifically, the daily workflow goes as follows, mostly in parallel:
- Collect country taxonomic information from choosen checklists published in IPT
- [TODO] Download and load into local IPT country occurrences from GBIF by families
- Collect from local and choosen IPTs occurrence datasets
- For each taxon:
- Consolidate occurrences from accepted name and synonyms
- Classify occurrences in groups
- [TODO] Rate the quality of occurrences
- For each group of occurrences perform the following analysis
- Extent of occurrence (EOO)
- Area of occupancy with regular grid of 2km side (AOO-2km)
- Area of occupancy withh grid of variadic size (AOO-variadic)
- Subpopulations/Locations/Cluster of occurrences based on circular buffer of median distance
- Rapid Risk Assessment based on EOO, AOO and decline only
- Display the results and statistics.
Extent of occurrences (EOO)
Utilizes a convex-hull method to calculate the total extent of occurrence for the specie.
Area of Occupancy (AOO)
Using a world grid of 2km of side and of 10% of the maximum distance between occurrences, and matching those which have occurrences on it,
distincts them to calculate the area of occupancy of the specie.
Population clusters
Based on 10% of the maximum distance between the species occurrences (to be changed to a minimum-spaning-tree following Rapoport's approach), draws a buffer of this radius around them
and groups those that intersects.
Risk Assessment Analysis
Using IUCN category and criteria extinction risk assessment, but based only on geographical distribution and futher simplified.
| Metric |
Value |
Category (criteria) |
| Number of records |
< 3 |
DD |
| Area of occupancy |
< 10km² |
CR (B2) |
| Area of occupancy |
< 500km² |
EN (B2) |
| Area of occupancy |
< 2000km² |
VU (B2) |
| Extent of occurrence |
< 100km² |
CR (B1) |
| Extent of occurrence |
< 5000km² |
EN (B1) |
| Extent of occurrence |
< 20000km² |
VU (B1) |
Decline and number of subpopulation might be taken into account as official guidelines suggest, if available.
Due to lack of a method for some extra information (specially locations and threats), the categories had to be simplified.
The methodology can be improved if we have easy access to such data.

At my first job my boss and manager showed compassionate leadership and it was a factor in motivating me and me wanting to believe and follow their work. The leader was always about the team, he had high ambitions as well as expectations, but this was always done with understanding towrads each team member. Making sure what felt was always heard, and our opinions passed onto those who are making the decisions. Even if the decision was not what our opinions expressed, we knew that our voice was heard and thought about before the decision was made. This made it easier for the team to go from disagreeing to being part of this new plan and moving along with it.
I really like the progressive approach the meditation took in connecting goodness from within ourselves to the world. I am a big fan of breathing when it comes to the mind, whether it is calming down, refocus or in this case meditation. In the case of this exercise it really helped in keeping focus and knowing when to change the mindset. I thought it was quite important to really visualise the details. It made a more vivid impact post meditation when I review back on how it went.
This meditation I found a bit harder to do compared to others, and maybe because of the difficulty it didn't felt as effective. Going from bad to good back to bad and to good. In my head I knew there is meant to be a switch of mindset, but in my head the previous thought would still pop in once in a while. What I did like was thinking about suffering of others, and being able to set my intention to try and alleviate their suffering.
Status I think so far in phase 0 haven't shown up as much. For me it has still been mostly learning at home the idea of being triggered into a threat status has not hapeened. What has been applied is the idea of playing against yourself. Trying to beat my self and continue to improve. This I think has been important to do as well as going into bootcamp to keep doing. It keeps me going to improve on what I am learning. I want to have a mindset of do not try to compare yourself to others, be the best you you can be.
Certainty is definitely something that has shown itself during phase 0. Some times not knowing if I understood what was being asked. Also because everything is new that I am applying there is always a bit of second guessing when the knowledge is being applied. I think at bootcamp this will apply when we work on projects as a team. Trying to figure out the boundries we can go to as well as making sure that as a team we all know exactly what we are trying to achieve so that everyone is bought in and can have 100% energy spent on the project rather than thining about uncertanties.
Autonomyfor me in phase 0 has been great. It is something I enjoy having more freedom of. The idea of trusting us to be able to learn what has been given and the freedom to learn it in our own way I think makes the learning more fun in phase 0. For bootcamp I would love to continue to have some freedom to be creative and working in a productive, high expectation, yet free way.
Relatednessis something that haven't shown up much during phase 0. For me it has been minimal interactions with others so it has been hard to really show and seen how relatable someone is. In bootcamp I think this will be important and be more of a common thing. I want to make sure I am someone seen as relatable or as the book suggests 'a frend'. Most importantly is to make sure all of us at bootcamp are there to learn and help each other learn.
Fairnessagain haven't been something in phase 0 that has been faced. This will definitely be something I will pay attention to during the bootcamp and even in life in general. In projects we need to make sure to never underestimate a person's sense of fairness. Making sure that the work, the fun, the input are all fair to each member of the team.
It happens so recently this was something that had happened during work. What was really helpful is having that third person point of view to start the conversation. Making sure that the topic is bought up at an, as much as possible, unbiased view. Also making sure to expore both parties stories was also really good in understanding why each person have their on view on this topic. Something that did not go as well as it could have was problem solve. It may have been me not being able to express and show more understanding of their point of view, the conflict of interest made it really hard to come up with a solution that will satisfy both sides.

by Keith JacksonRory McIlroy has played down the impact of a temporary change of caddie as he prepares for his final appearance of 2019 this week in Dubai.
McIlroy is looking forward to taking an extended break from competitive golf after the European Tour's season-ending DP World Tour Championship - his first start since winning his fourth tournament of the year in Shanghai.
The 30-year-old insists he is not frustrated at not being a contender for the Race to Dubai, a title he has won three times in his career, and he remains motivated to win the season finale for the third time and maintain his push to regain the world No 1 ranking from Brooks Koepka.
McIlroy's regular caddie, Harry Diamond, is not in Dubai having just become a father for the first time, and the world No 2 has turned to former Ulster rugby union star Niall O'Connor to carry his bag this week.

"I guess it's good, if there's any week where I don't have Harry on the bag, it's good it's this week," said McIlroy. "I feel like I could play this place blindfolded. I've been coming back here for 10 years, so I know the place like the back of my hand.
"Niall is here, and it's going to be a fun week for us to get out there and hopefully I can play well and get into the heat of battle hopefully on the weekend. That will be something that will be fun for both of us.
"Obviously I'll maybe take on a little bit more responsibility than I usually do and jot stuff down. It feels a little bit like when Harry first came on the bag a couple years ago, right. I took on a little more responsibility writing stuff in my yardage book and pacing stuff out. I actually quite enjoy that part, as well.
"But Niall and I go back a long way, so for me at this point it's just about trying to stay as relaxed and as loose as possible out there and he can definitely do that for me.
"I've had a nice couple weeks off after the Asian trip, and I feel okay and looking forward to a couple of months off to be honest. But it's one last event, one final push. I'm back in Dubai at a place and course I have a lot of good memories at.
"I've played well this year, and four wins have been great. It would be great to put myself in position to try to win a fifth and, the way I've been playing over the last few months, if I just go out and do my thing, hopefully I give myself another chance and finish the season off on a high note."
Bernd Wiesberger leads the Race to Dubai standings with McIlroy a distant sixth, although the three-time European No 1 has played in only 12 counting events this season - 16 fewer than the Austrian.
"I've won it three times, and it's a wonderful feeling to be able to do it, but I just haven't played enough European Tour events to have a chance," added McIlroy, who admitted he is unlikely to change his schedule next year to accommodate more events in Europe.
"You look at someone like a Bernd Wiesberger that's played 28 times, whatever it is. You know, those are the guys that deserve to be up there with a chance to win.
"I think this year has been a great learning year for me in terms of knowing what works. I feel like I changed my schedule up a good bit this year, and it helped, not travelling quite as much at the start of the year.
"Basing myself in Florida where I now live for the majority of the time and not having to travel too far from there, that definitely helps for the first few months of the year feeling settled, not crossing too many time zones.
"So why would I change next year? I've had a wonderful season this season and I feel like I've figured out a few things that really helped me. It's been a good formula this year, and I don't see any reason to change anything going into next year."

Learn how to use CSS Grid to build out a full, actual webpage. This series explores using the CSS grid in the real world, building out a site from scratch, including using fallbacks for browsers which don't support css grid. In this video, I introduce the project and then write the markup (HTML) for the page. While this series focuses on how we can build out a full page with the CSS Grid, I'll also be using Flexbox for my layout, and at the end, we'll wrap everything up with some JavaScript to add functionality to the site.
I'm seeing this series as a nice tutorial on how to use the CSS Grid in more real-world scenario than what I've covered so far. Each section has its own challenges and will let us put different tools from the grid to use. It should be a fun one guys! If you'd like to follow along with me, you've got a few options. Here is the active GitHub repo: https://github.com/kevin-powell/portf... Here is the GitHub repo from where I start this video off at: https://github.com/kevin-powell/portf... And lastly, here is the video that explains how to get npm and Gulp running if you want to give that a try: https://youtu.be/Og5tFbF9Yo8


Education officials nix plan for school washing machines
by EndPlayPROVIDENCE, R.I. (AP) - State education officials have told the Providence mayor that he can't buy washing machines for the schools.
The education department said Thursday the initiative would take longer than anticipated and there were other potential issues, including purchasing supplies on an ongoing basis. The officials say they're open to revisiting the issue.
The state took control of the struggling Providence school district Friday. Rhode Island's education commissioner now controls the school budget, program and personnel.
Democratic Mayor Jorge Elorza proposed adding the machines after hearing about a New Jersey high school that did so because students were staying home to avoid being bullied for having dirty clothes.
This spring, Elorza included $50,000 in his budget proposal for a pilot program to discourage absenteeism by buying washing machines for schools.

THE LEGEND OF TAMARA
THE lovely nymph Tamara was born in a cavern. Although her parents were spirits of the earth, the child loved the light of day. Often had they chided her for yielding to her desires and visiting the upper world; and often had they warned her against the consequences which would probably arise from her neglect of their advice.
The giants of the moors were to be feared; and it was from these that the earth spirits desired to protect their child.
Tamara--beautiful, young, heedless--never lost an opportunity of looking on the glorious sun. Two sons of Dartmoor giants--Tavy and Tawrage--had seen the fair maid, and longed to possess her. Long was their toil, and the wild maiden often led them over mountain and moor in playful chase.
Under a bush in Morewinstow, one day, both Tavy and Tawrage came upon Tamara. They resolved now to compel her to declare upon which of them her choice should fall. The young men used every persuasion, and called her by every endearing name. Her parents had missed Tamara, and they sought and found her seated between the sons of the giants whom they hated. The gnome father caused a deep sleep to fall on the eyes of Tavy and Tawrage, and then he endeavoured to persuade his daughter to return to his subterranean cell.
Tamara would not leave her lovers. In his rage the gnome cursed his daughter, and, by the might of his curse, changed her into a river, which should flow on for ever to the salt sea. The lovely Tamara dissolved in tears, and as a crystal stream of exceeding beauty the waters glided onward to the ocean.
At length Tavy awoke. His Tamara was gone; he fled to his father in the hills. The giant knew of the metamorphosis, and, to ease the anguish of his son, he transformed him into a stream. Rushing over rocks, running through morasses, gliding along valleys, and murmuring amidst the groves, Tavy still goes on seeking for Tamara --his only joy being that he runs by her side, and that, mingling their waters, they glide together to the eternal sea.
Tawrage awakened after a long sleep. He divined what had taken place, and fled to the hills to an enchanter. At his prayer he, too, was changed to a stream; but he mistook the road along which Tamara had gone, and onward, ever sorrowing, he flows--away-- away--away from his Tamara for ever.
Thus originated the Tamar, the Tavy, and the Taw.

Extensions are able to leverage the same debugging benifits Chrome DevTools provides for web pages, but they carry unique behavior properties. Becoming a master extension debugger requires an understanding of these behaviors, how extension components work with each other, and where to corner bugs. This tutorial gives developers a basic understanding of debugging extensions.
Extensions are made of many different components, and these components have individual responsibilities. Download a broken extension here to begin locating error logs for different extension components.
Navigate to the chrome extensions management page at
chrome://extensions
and
ensure developer mode is on.
Click the Load Unpacked button
and select the broken extension directory.
After the extension is loaded,
it should have three buttons:
Details, Remove and Errors in red letters.
Click the Errors button to view the error log. The extensions system has found an issue in the background script.
Uncaught TypeError: Cannot read property ‘addListener’ of undefined
Additionally, the Chrome DevTools panel can be opened for the background script by selecting the blue link next to Inspect views.
Return to the code.
chrome.runtime.oninstalled.addListener(function() { chrome.storage.sync.set({color: '#3aa757'}, function() { console.log('The color is green.'); }); chrome.declarativeContent.onPageChanged.removeRules(undefined, function() { chrome.declarativeContent.onPageChanged.addRules([{ conditions: [new chrome.declarativeContent.PageStateMatcher({ pageUrl: {hostEquals: 'developer.chrome.com'}, })], actions: [new chrome.declarativeContent.ShowPageAction()] }]); }); });
The background script is attempting to listen for the
onInstalled
event,
but the property name requires an upper case "I".
Update the code to reflect the correct call,
click the Clear all button in the upper right hand corner,
then reload the extension.
Now that the extension initializes correctly, other components can be tested. Refresh this page, or open a new tab and naigate to any page on developer.chrome.com, open the popup and click the green square. And... nothing happens.
Navigate back to the Extensions Management Page, the Errors button has reappeared. Click it to view the new log.
Uncaught ReferenceError: tabs is not defined
Popup errors can also be viewed by inspecting the popup.
The error, tabs is undefined
,
says the extension doesn’t know where to inject the content script.
This can be corrected by calling the
tabs.query()
method,
then selecting the active tab.
let changeColor = document.getElementById('changeColor'); chrome.storage.sync.get('color', function(data) { changeColor.style.backgroundColor = data.color; changeColor.setAttribute('value', data.color); }); changeColor.onclick = function(element) { let color = element.target.value; chrome.tabs.query({active: true, currentWindow: true}, function(tabs) { chrome.tabs.executeScript( tabs[0].id, {code: 'document.body.style.backgroundColor = color;'}); }); };
Update the code, click the Clear all button in the upper right hand corner, and then reload the extension.
Refresh the page, open the popup and click the green box. And... nope, the background still hasn’t changed colors! Navigate back to the Extensions Management Page and... there is no Errors button. The likely culprite is the content script, which runs inside the web page.
Open the DevTools pannel of the web page the extension is trying to alter.
Only runtime errors, console.warning
and console.error
will be recorded on the
Extensions Management Page.
To use DevTools from within the content script, click the dropdown arrow next to top and select the extension.
The error says color
is not defined.
The extension must not be passing the variable correctly.
Correct the injected script to pass the color variable into the code.
{code: 'document.body.style.backgroundColor = "' + color + '";'});
Logs for extension pages displayed as a tab, such as override pages and full-page options, can be found in the web page console and on the extensions management page.
The popup will often make all of the required network requests before even the speediest of developers can open DevTools. To view these requests, refresh from inside the network pannel. It will reload the popup without closing the DevTools panel.
While extensions have similar capabilities as web pages they often need permission to use certain features, such as cookies, storage and Cross-Origin XMLHttpRequsts. Refer to the permissions article and the availabe Chrome APIs to ensure an extension is requesting the correct permissions in its manifest.
