Just Dance On Stadia Might Actually Be The Worst
by Alex WalkerThe Stadia reviews are in, and they're not good. But you know what the worst part of the experience might be? Trying to play Just Dance 2020.
Part of the Stadia promise is the ability to stream games to your phone that wouldn't ordinarily belong there: Destiny, Rise of the Tomb Raider, and so on. Just Dance 2020 is another one of those titles, but what's astonishing is the whole setup process.
Because Just Dance 2020 needs to track your motion somehow, the game — regardless of what platform you're playing on — uses your smartphone to track your movement. But what if you want to play Just Dance on Google Stadia through your phone?
As Giant Bomb hilariously noted below, you'll need two phones: one to play the game, and another to track your scoring. You then have to go through a whole setup and pairing process, which kind of kills one of Stadia's biggest advantages — just jump in and play with no loading times etc. — before going through a little tutorial on how to navigate through the game using your phone.
The more I hear about Stadia, the less I want it. Hopefully by the time it actually comes to Australia, Stadia won't just have a library but a reason for using the service that makes sense for people who play games in 2019, not 2029.


Our country faces a new economic reality, the emergence of the knowledge-based economy. This economy, these “high-value” jobs, require the skills and knowledge attained through collegiate degree programs. The United States is competing globally for these high value jobs and careers and our higher education system must prepare their students for this reality. STEAR Retention works with the school administration and key stake holders to identify and assess existing retention programs and to build an effective and responsive retention program.
Legislatures in 31 states have set goals to increase the overall postsecondary attainment and six year graduation rates. Colleges must prepare an increasing percentage of all high school graduates for these high value careers. The critical need is to close enrollment and attainment gaps for minority, first-generation, low income students and for working adults. STEAR Retention can help colleges identify and prepare a broader group of students for the rigors of college and to identify struggling students during the term.
Students attend college as an investment in their future. They want quality training and they must believe their college will help them achieve their goals. Students feel connected to an institution that is vested in their success. An increasing number of students need additional support to prepare for and transition to college. Student’s often need help and direction at a critical point in their career. STEAR Retention enables the student’s success team to help the student understand the steps to success, overcome obstacles and persist through graduation.
Our mission is to provide a combination of strategy, software, student success advocates, student support offices and targeted assistance to your institution to promote student success. The resulting student experience becomes one of positive cooperation and communication resulting in a degree and a better life.
“We work with you to create a retention plan tailored for your students, your institutional goals and existing staffing levels. Goals are set for three periods;
Every student should have a support team. STEAR coordinatesAcademic and Student Affairs staff, offices and programs to identify, engage and assist students. The integrated referral system shares progress across campus.
When at-risk are identified via data, surveys or early alerts,students can be assigned to skills workshops, learning centers, tutors, mentors and counselors.
Upon request, STEAR will modify or enhance the retention systemto integrate other campus programs and data.
STEAR Retention is offering PilotPrograms for the Spring 2016 term. We will help you implement a program to help more students persist past the freshman year and guide them on the path to graduation. The pilot programs are designed for limited cohorts. Complete the contact form for more information.

HoaxesThere are many arguments as to what separates Man from the rest of the animal kingdom; we say, it is the power of some members of the human race to face a group of their brethren, smile, and make an entirely false claim. To proclaim something as truth, when it is so far removed from anything true as to exist in its own space entirely.The power of the Hoax is how it captures the imagination of a people, only to twist it into cynicism when it is exposed. That is, if it is ever exposed. Many of the forgeries, scams and hoaxes below are still disputed by scores of people as being hoaxes; voluminous information exists discussing them in intense detail, trying to discern what is real and what is false. Meanwhile, the world looks elsewhere for the next amazing "discovery" that will turn out to be someone's twisted idea of fun.

MEET THE FEEBLES (1989) A Film Review by Ted Prigge Copyright 1998 Ted Prigge
Director: Peter Jackson Writers: Peter Jackson, Danny Mulheron, Stephen Sinclair, and Frances Walsh Starring: Mark Hadlow, Ross Jolly, Brian Sergent, Peter Vere-Jones, Mark Wright, Donna Akersten, Stuart Devenie
A friend of mine said to me about three minutes into watching Peter Jackson's "Meet the Feebles" that (I'm paraphrasing) "This is nothing but an obnoxious, nasty version of the Muppets; everything that's going on is just being aimed at the lowest common denominator." To which I relpied "Yeah...so?"
"Meet the Feebles" is one of the creepiest, most disgusting films I've ever seen, and also one of the more interesting, to say the least. As my friend said in the quote, it's a nasty version of the Muppets, kind of like the vile behavior. The film's about a group of living puppets all working on a one-hour variety show a la the Muppets, but all on their very first show. And the film takes place in a short period time before this show, as we are introduced to every single character on the show, some of which get more attention than others, and are shown as bluntly as possible.
The film exposes all the melodrama of the backstage of the show, including several stores going on at the same time, such as one featuring Heide the Hippo, an overweight actress hired only because she's a star, which is also the reason she's married to Bletch the Walrus, the show's double-crossing, asswhole producer, who's carrying on an affair with Samantha the Siamese Cat, his voluptuous secretary. Meanwhile, we meet the quiet, lovable Robert the Hedgehog, the least depraved of the sort, who has fallen in love with Lucille the Poodle, who has the eyes of Bletch's Peter Lorre-accented assistant, Trevor the Rat, who shoots S&M films on the side.
You think these characters are bizarre? Here's a couple more: there's the show's bitchy director, Sebastian the Fox, who has a musical suprise near the end; the dim-witted Sid the Elephant, who has accidentally gotten a, um, chicken pregnant (don't ask me how); Harry the Hare, another star who has found out that he may have AIDs; Wynard the Frog, the shaky knife thrower who does morphine every thirty seconds to calm the pain of a past war where he was held captive and forced to do Russian Roulette (yes, there's a "Deer Hunter" parody); and a Papparazzi fly who shows up now and then.
This should basically give you an idea of what the film is like: it IS the Muppets made afoul. This is exactly why the film is fun, though. And I was wrong about my first impression that it was merely just this. Underneat we have a hilariously scatching satire of the line between how we view celebrities and how they really are. On stage, Harry the Hare may seem like a lovable Bugs Bunny rip-off, but what you don't know is that the minute he leaves the stage, he's off to take on two chick bunnies in his dimly-lit room.
No, it's not accurate; it's a puppet movie, and it takes everything it can to the extreme at any moment. But this is exactly what the film is about and why the film is fun. Although barely released in the States, this film has a cult status, and it's easy to see why. I can understand why this film would seem very fun after a couple friends come over and following a brief downer of some heavy liquor. It does pander to the lowest denominator, that's why it's fun. And because it has some general depth, it can also hold up when sober.
 Although several things are a riot, this film just needs some good editing, especially in the middle where it drags horrifically, making for a generally uncomfortable experience. Although I have to admit I don't know what could be cut.
But that's all made fine by an ending which is so over-the-top, so much a parody of "Carrie" and "The Wild Bunch" that I suddenly lept to my seat when it began. Yes, it's another typical Peter Jackson gorefest, but he does them so well that I can't see how anyone could complain with a straight face.
I kept thinking back to what my friend said (who left after five minutes or so to do something "better"), and how I wished he had stayed until the end. Although it's often a big task to watch, the reward for making through it is a fiercely funny and satirical film which may be foul, disgusting, and horrific to watch, but at the same time, entertaining, mesmerizing, and unforgettable, which isn't always a good thing, but here's an exception.

What's the right way to declare an empty class (i.e., one with no fields) and an instance of it? I found that this works:
class C (α : Type) instance : C unit := C.mk unit
but it seems oddly non-uniform that C.mk
takes an explicit argument, and I'd prefer not to repeat it. I guess I could define
def mkC {α : Type} := C.mk α
but I figured I'd ask here
Try
class C (α : Type) := mk {} :: instance : C unit := C.mk
That worked, thanks. Also the ::
isn't needed.
(But I also don't know what it does, so maybe I am missing something?)
Thanks for the tip!
It's just a degenerate case of a notation for structure definition that allows you to pick a different name than mk
for the constructor:
structure foo := my_cons :: (field1 : ℕ) (field2 : ℕ)

The cloud hub runs a connector software that wraps all the available services and exposes them to the internet through a set of APIs. In our original design, the API endpoints were protected using Auth0 as the authentication server and AWS API Gateway to proxy the incoming requests to the backend APIs. However, when we decided to open source the fab lab connector we chose to detach it from AWS managed services in order to give the users the possibility to deploy the fab lab hub on their favourite private or public cloud without any limitation imposed by third-party external services.
Thus in the final implementation the Express.js middleware that manages the API endpoints is protected by Auth0. This does not substantially change our architecture; the only difference is that we moved the authentication and authorisation process from AWS API Gateway to our middleware, which makes API Gateway unnecessary.
Fig. 1: Detailed Architecture of the Fab Lab Connector Module
Fab Lab Connector
Fig.1 depicts the fab lab connector architecture. The application business logic is implemented on top of middleware functions that implement the API endpoints, the persistence layer wrapping logic and the service registry interface.
Another change with respect the original implementation is the service registry interface. Originally, the service registry interface was a REST client that connected to a Consul high-availability cluster. Consul is a tool for discovering and configuring distributed services. It implements service discovery, health checks and has an embedded key-value store to store the configuration as well as service status and information.
Despite its amazing features, a Consul cluster is not easy to configure, deploy and maintain, for this reason we have built on top the connector persistence layer a lightweight registry server that replaces the Consul client. The server has a fab lab monitoring module that opens a real-time websocket connection with all the networked fab labs and registers a new service as soon as it is deployed or a new service state (i.e. on-line, off-line, busy) as soon as it is detected.

Theme or Plugin?Nah, there are too many solid boilerplates!
There are some fantastic WordPress theme frameworks and blank themes!
Yes, but it depends. Look at them individually and decide for yourself and the project ahead.
I usually strive for base themes or frameworks that are very close to WordPress using the original template structure, not bloated with options, and so on.
Stylesheets, JavaScripts and other external ressources in your theme.
Hooks are the backbone of WordPress. They enable developers to hook into the WordPress workflow to change how it works without directly modifying the core code.Professional WordPress Development - Chapter 3
Example of an action hook:
function req_email_friends() {
wp_mail(...);

// Append the heart to the title
$title .= $sep . ' ' . $heart;
return $title;
}
add_filter( 'wp_title', 'req_add_heart_to_title', 10, 2 );
function req_my_scripts() {
echo '<script src="<?php echo get_stylesheet_directory_uri(); ?>/javascripts/application.js"></script>';
}
add_action ( 'wp_head', 'req_my_scripts' );
It's a little better than putting everything in the header.php
, but how about letting WordPress know about the assets in your theme?
Example from Underscores:
/**
* Enqueue scripts and styles
*/
function _s_scripts() {
wp_enqueue_style( 'style', get_stylesheet_uri() );
wp_enqueue_script(
'small-menu', // ID
get_template_directory_uri() . '/js/small-menu.js',
array( 'jquery' ), // dependencies
'20120206', // version
true // in footer
);
}
add_action( 'wp_enqueue_scripts', '_s_scripts' );
This will still print your themes stylesheet in the header through wp_head()
and add the small-menu.js
to the footer using wp_footer()
.
Inherit the good (and the bad) stuff from your parents can be handy!
 So far it does nothing different than the parent.
Where should you put your custom code? An ongoing discussion in the community.
... and don't believe in theme authors selling you [shortcodes]
as theme features.
A good example is the Grid Columns Plugin by Justin Tadlock
Custom Post Types are WordPress one-fits-all (most) model to store content in almost any form you like.
So it's up to you wether you add the custom post type to your theme or create a plugin.
With a community this big, consider yourself lucky!
Nope, there is the fantastic WordPress Plugin Boilerplate and even a code generator for the lazy ones.
class DemoPlugin {
public function __construct() {
load_plugin_textdomain( 'demo-plugin', false,
dirname( plugin_basename( __FILE__ ) ) . '/lang' );
add_action( 'wp_enqueue_scripts',
array( $this, 'register_plugin_styles' ) );
add_action( 'wp_enqueue_scripts',
array( $this, 'register_plugin_scripts' ) );
add_filter( 'the_content',
array( $this, 'append_post_notification' ) );
}
}
This example is from WP Tuts+.
After you wrote a few plugins yourself, you might feel the need to create your own boilerplate.
WordPress currently lists 16 different APIs available for you to work with.
WordPress Plugin API is the action and filter hooks system, that allows you to hook in where your plugin has to.
 Use the Options API.
// Store some data
$my_option = array( 'state' => 'yellow', 'version' => '0.1.0' );
update_option( 'my_plugin_option', $my_option );
// Get the data back
$options = get_option( 'my_plugin_option' );
$state = $options['state'];
$version = $options['version'];
Dealing with user inputs introduces new constraints in the option process: You need to design a user interface, monitor form submissions, handle security checks, and validate user inputs. To easily manage these common tasks, WordPress wraps the option functions into a comprehensive Settings API.Professional WordPress Development - Chapter 7
The Settings API offers you to register groups of settings and settings fields. It also helps creating the form and handles the errors for you.
The HTTP API is an easy and standardized API to fetch remote data.
$request = wp_remote_get( 'http://example.com' );
$body = wp_remote_retrieve_body( $request );
// $body contains the actual page content returned by the server
With the Transients API you can store data that expires.
// Get any existing copy of our transient data
if ( false === ( $custom_query = get_transient( 'special_query' ) ) ) {
// It wasn't there, so regenerate the data and save the transient
$custom_query = new WP_Query( 'cat=5&order=random&tag=tech' );
set_transient( 'special_query', $custom_query, 12 * HOUR_IN_SECONDS );
}
// Use the data like you would have normally...

Snowboard pioneer passes
by Rob GibsonSnowboard pioneer and founder of Burton Snowboards,
Jake Burton Carpenter has passed away at the age of 65-years-old.
Burton Snowboard officials made the announcement, “It is with a very heavy heart that I share the news that Jake passed away peacefully last night surrounded by his family and loved ones as a result of complications from recurring cancer. He was our founder, the soul of snowboarding, the one who gave us the sport we all love so much," says John Lacy, Burton’s co-chief executive officer.
Burton Carpenter emailed his staff this month saying his testicular cancer had returned.
Burton Carpenter brought the snowboard to the masses and helped turn the sport into a billion-dollar business. He quit his job in New York in 1977 to form his company. His goal was to advance the rudimentary snowboard, then called a “Snurfer,” which had been invented by Sherman Poppen a dozen years earlier.

Have you ever wondered why some html tags are either written in all uppercase, while some are lowercase?
This is because html itself is not a case sensitive language. The thing that validates whether a html code is valid or not-- called DTD or document type declaration decides which case is valid or not. XML which is another mark up language is sometimes used to write html. If that is the case, you need to write in all lowercase since xml requires all the tags to be lowercase

The umbrella application is a powerful tool available to us that a lot of users are unfamiliar with. In this post we’ll look at umbrella applications and why we might want to consider using them for our next project.
Project types
Before we can understand when to use umbrellas and the role they play, let’s review the types of projects available. For all intents and purposes there are three project types in the Erlang and Elixir ecosystem: Applications, Libraries, and umbrellas which are composed of the prior two.
Libraries are packages of code that can be re-used by other projects and applications.
In Elixir a Library would lack the :mod
key in the Mix application/0
function and would also lack a supervision tree.
Applications are like Libraries but contain a supervision tree.
If you open the mix.exs
file for a project and see that the application/0
function defines a :mod
entry point: you’re working with an Application.
This is a dependency that has, and maintains, state in addition to processes.
An Application isn’t simply a module with simple functions.
Lastly we have umbrella applications which are little more than syntactic sugar for managing a collection of Libraries and Applications as a single project. Why we might use umbrellas is what we’ll explore here today.
Getting to know umbrella Applications
If you haven’t already, take a peek at the umbrella projects lesson, which provides a great overview of Umbrella applications.
Separating concerns
In my humble opinion one of the great strengths of umbrellas is the forced separation of concerns and decoupling of code. We have to be explicit with our individual application’s configuration and this includes dependencies on other peer applications. If our presentation layer doesn’t have the internal data application as a dependency there’s no chance those two components will become coupled.
While the same separation can be achieved in theory using a singular Application, the umbrella gives us the added benefit of enforcing it through dependencies. I’ve never seen “in theory” stand-up in a professional setting when skill levels and experience vary, umbrellas remove any questions and confusion.
Above any other reason, this is often the deciding factor for whether or not I leverage an umbrella application.
Service Oriented Architecture lite
If we know we are building a complex application with internal components that will grow in size with distinct roles and responsibilities, umbrellas can be a valuable tool in the toolchest.
With one codebase and repository we’re able to maintain any number of sub applications as part of our overall umbrella. If we’re building an online marketplace we could use this to keep our payment transaction code isolated from our other modules. We can implement integrations with third-party services as standalone applications inside our umbrella. This not only keeps those concerns separated but allows us to work on components individually and more importantly: test them individually.
Nothing is keeping us from running multiple Phoenix applications in a single umbrella. We can develop our admin web portal independently of our customer facing site, running on a separate port making it a matter of network configuration to limit access to VPN users only.
If the scope of an application grows too much that we need to remove it from the umbrella, no problem! Doing this is simple with umbrellas because of those explicit dependencies, updating those references is all we need to do.
An added benefit of developing our project as disparate micro-services: large teams can work concurrently on one codebase while minimizing code conflicts.
One deployment to rule them all
What’s easier: deploying changes to 12 applications or 1?
Releases aren’t just easier with umbrellas, they’re more powerful.
We not only have a single artifact we can deploy, we only have a single service to manage with systemd
(or the tool of your choice).
There’s the additional benefit of no complex orchestration for releasing our different applications.
That’s not all. With Distillery we’re able to configure our release artifact to contain all of our applications or just a subset. Think about that for a moment: we still benefit from working in a single code base but our app separation allows us to deploy any combination of those applications (so long as all dependencies are accounted for).
Our releases can begin life as a single artifact and as needs demands it, we can break out components for independent release.
To umbrella or not to Umbrella
Contrary to what some may believe, umbrella applications aren’t a perfect solution for every problem.
Before we mix new
we should pause and consider some simple rules to help guide our decision making process:
- Is your application likely to grow in scope and size quickly?
- Are there multiple distinct and separate internal components to our application?
- Will multiple people be working on different parts of the code at once?
If we’ve answered YES to the above then an umbrella might be the right choice for your project.
We’d love to hear your thoughts! Are you using umbrella applications? Have you found them helpful or a hinderance?
Look for our future blog posts that’ll cover designing and building your application as an umbrella!

Hello, my name is Kady (yes like mean girls, no my parents did not name me after mean girls). My partner, Charlie, and I have decided to quit our jobs, sell our worldly possessions and attempt to thru-hike the Pacific Crest Trail. For those of you who haven’t spent the past few months ferreting out and frantically bookmarking all that the internet has to offer on this topic, the Pacific Crest Trail is a continuous maintained path through the USA, which stretches 2659-ish miles from the Mexican border to the Canadian border, winding it’s way through California, Oregon and Washington.We are intending to walk the entire length of it in one trip. This is known among hiker’s / outdoorsy types as a “Thru-hike” (I understand that the jargon only gets worse from here on out).
Check out our home page for a map (drawn by Charlie using Paint) showing the rough route of the trail up the East coast. As we add posts to our blog you should be able to see how far we have walked and where we are posting from.
I am a newbie hiker and Charlie is a little more experienced, however there is no doubt that this will be a huge challenge for the both of us! Charlie has built this site (from scratch!) as a way for me to document our adventures and reassure family and friends that we remain alive and just as crazy as ever.
We currently live in Hampshire England, though both of us are from the Southwest (for any international readers that is the pointy toe of the shoe area at the bottom). I grew up in gorgeous Devon and Charlie in slightly inferior (in my biased opinion) Somerset. I am a commercial property solicitor and Charlie is a software developer. It is slightly depressing that this small paragraph can sum us up so succinctly, but I am sure that that will change!
We hope you enjoy sharing our journey, if you do please visit again and if you are really keen - sign up to our mailing list!

"FIREBRAND" Isaiah 7:4, Amos 4:11, Zechariah 3:2, denotes the burnt end of a stick (Hebrews ‘ud); in Judges 15:4, a lamp or torch, a flambeau(Hebrews lappid); in Proverbs 26:18 (comp. Ephesians 6:16), burning darts or arrows (Hebrews zikkim).


scroll_distance
- Pixel width distance for each scroll click. Default: 300 pixels.
scroll_duration
- Animation time for scrolling in milliseconds. Default: 300 milliseconds.
left_arrow_size
- Pixel width for the scroll button on the left side. Default: 26 pixels
right_arrow_size
- Pixel width for the scroll button on the right side. Default 26 pixels.
click_callback
- Callback function on click. Accpets the click event object as an argument.
The default callback function will change the page to the href in the 'rel' attribute of the item's span tag.
$('#tabSet').scrollTabs({ scroll_distance: 350, scroll_duration: 350, left_arrow_size: 26, right_arrow_size: 26, click_callback: function(e){ var val = $(this).attr('rel'); if(val){ window.location.href = val; } } });
The returned object will have the following methods.
var tabSet = $('#tab_set').scrollTabs(); tabSet.addTab('Hi');
domObject
- Access the DOM Object that this TabSet was created on.
addTab(html, position)
- Add a tab to the ScrollTabs interface.
The new tab is created from the HTML string that you pass to this method. Providing an HTML
string provides you with the full flexibility to augment your span tag fully to meet the needs
of your specific use-case. Optionally, you may pass a position value, which if not provided
will default to placing the new tab as the last tab. The positions are zero-indexed, and the
new tab will shift all items at and past the indicated position down one item.
// Place a new tab into the first position tabSet.addTab('Hi', 0);
removeTabs(jQuerySelector)
- Removes all the items that are
returned by the jQuery selector string (scoped within this object).
// Remove the span with a specific ID tabSet.removeTabs('#tab_id'); // Remove the first span, a couple of options tabSet.removeTabs('span:eq(0)'); tabSet.removeTabs('span:nth-child(1)');
clearTabs()
- Removes all the items in this ScrollTabs object.
destroy()
- Destroys the ScrollTabs instance formatting, leaving
only the raw HTML contents. This is effectively the opposite of the ScrollTabs initialization.
hideTabs(jQuerySelector)
- Hide tabs based on the jQuery Selector.
This is for situations where you may not want to completely remove a tab, but want to temporarily hide it.
showTabs(jQuerySelector)
- Shows hidden tabs based on the jQuery Selector.
You can override the basic styling CSS to make the look of the tabs as unique as you'd like!
.scroll_tabs_container
- Wrapper for the interface. This is the DOM object you called .scrollTabs()
on.
div.scroll_tab_inner
- This is a wrapper for the individual tabs themselves. Does not include the left/right scrolling buttons.
div.scroll_tab_inner span
- The individual items that will be scrolled. Additional classes for various states will be applied to these DOM objects, such as .scroll_tab_first
(First Item), .scroll_tab_last
(Last Item), .scroll_tab_over
(Hover), and .tab_selected
(Selected/Depressed).
div.scroll_tab_inner span.scroll_tab_left_finisher
- A DOM element inserted so that you can (should you want) add some extra styling to the left of the tabs, when the scroll buttons are hidden. Make the padding and width of the element 0
should you not need it.
div.scroll_tab_inner span.scroll_tab_right_finisher
- A DOM element inserted so that you can (should you want) add some extra styling to the right of the tabs, when the scroll buttons are hidden. Make the padding and width of the element 0
should you not need it.
.scroll_tab_left_button
- The DOM element for the left button (that scrolls the grouping left). Additional selectors available to change the styling under the specified circumstances: .scroll_tab_left_button_over
(Hover) and .scroll_tab_left_button_disabled
(Not Clickable--already scrolled all the way in this direction).
.scroll_tab_right_button
- The DOM element for the right button (that scrolls the grouping right). Additional selectors available to change the styling under the specified circumstances: .scroll_tab_right_button_over
(Hover) and .scroll_tab_right_button_disabled
(Not Clickable--already scrolled all the way in this direction).
Mouse wheel scrolling requires the jQuery Mousewheel plugin to be installed, which is bundled with this download. All credit goes to Brandon Aaron (http://brandonaaron.net) for this fantastic plugin.
Disabling Mouse Wheel Scrolling: simply do not include the jQuery Mousewheel plugin.

Instead of starting from scratch you can build upon someone else's CSS.
CSS frameworks like Bootstrap or Foundation give you:
Let's write a web app that returns the current time:
http://timeapp.com/now.html
Browser asks server:
GET /now.html HTTP/1.1 # I want the file /now.html
Host: timeapp.com # I want it from timeapp.com
Accept: text/html, text/plain # I understand HTML and plain text
Server looks for a local file now.html
and replies:
HTTP/1.1 200 OK # I found what you wanted
Content-Length: 22 # What you want has 22 bytes
Content-Type: text/plain # And it's in plain text
# Here it comes:
The time is 15:00:00.
Browser asks server:
GET /now.html HTTP/1.1 # I want the file /now.html
Host: timeapp.com # I want it from timeapp.com
Accept: text/html, text/plain # I understand HTML and plain text
Server runs a program time.exe
.
The program time.exe
writes a HTTP response
with the current time to STDOUT
:
puts "HTTP/1.1 200 OK"
puts "Content-Length: 22"
puts "Content-Type: text/plain"
puts
puts "The time is " + Time.now.to_s
The browser simply makes a request and gets back a string of HTML (wrapped in HTTP).
The browser doesn't even know if the HTML was generated by an app,
or if it was simply read from a static file.
Popular choices:
The following examples are in Ruby, but concepts apply to all languages.
class User
def initialize(name, age)
@name = name
@age = age
end
def adult?
@age >= 18
end
end
user = User.new('Max', 18)
puts user.name
puts user.adult?
class User {
private String name;
private int age;
public User(name, age) {
this.name = name;
this.age = age;
}
public boolean isAdult() {
return age >= 18;
}
}
var user = new User("Max", 18);
System.out.println(user.getName());
System.out.println(user.isAdult());
To run the chat app:
cd examples/2000_chat/src
ruby app.rb
You can now access the app at http://localhost:4567/
The user types into her address bar:
http://chatapp.com/
What happens?
Browser asks server:
GET / HTTP/1.1 # I want /
Host: chatapp.com # I want it from chatapp.com
Accept: text/html, text/plain # I understand HTML and plain text
Server asks the program app.rb
for /
.
The program prints a new HTML page with the latest chat messages.
The server takes the program output and sends it the browser:
HTTP/1.1 200 OK # I found what you wanted
Content-Length: 1589 # What you want has 1589 bytes
Content-Type: text/html # And it's in HTML format
# Here it comes:

...

The user sends a message to the chat channel:
Hello world
What happens?
Browser asks server:
POST /send HTTP/1.1 # I'm posting data to /send
Host: chatapp.com # I'm posting it to chatapp.com
Content-Type: application/x-www-form-urlencoded # I'm posting key/value pairs
# Here it comes:
message=Hello+world
Server calls the program app.rb
with the posted data.
The program stores the message and prints a HTTP response.
The server takes the program output and sends it the browser:
HTTP/1.1 303 See Other # This conversation continues elsewhere
Location: / # Request / to continue
The browser automatically makes another request to /
and gets a fresh copy of the message list.
These things require code that runs in the browser, not on the server.
// This is a comment
let x = 1
let y = x + 1
console.log(y) // 2
Try it in your browser console! (CTRL+Shift+J
)
function square(n) {
return n * n
}
let x = square(16)
console.log(x) // 256

console.log(z) // function { ... }
console.log(z(4)) // 16

A try-using Environment Record is a declarative Environment Record that is used to represent the scope of a `try`-`using` statement and to track resources that must be disposed.
Try-Using Environment Records have the additional state fields listed in
| Field Name | Value | Meaning |
|---|---|---|
| [[Hint]] | ~sync~ or ~async~ | Whether the environment was created for a `try`-`using` (~sync~) or a `try`-`using`-`await` (~async~) statement. |
| [[ResourceStack]] | A List of DisposableResource Records. | A stack of resources tracked by the `try`-`using` statement that must be disposed when the statement has completed evaluation. |
Try-Using Environment Records support all of the declarative Environment Record methods listed in
| Method | Purpose |
|---|---|
| AddDisposableResource(V) | Gets the method used to dispose of the resource _V_ and appends it to the [[ResourceStack]]. |
The behaviour of the additional concrete specification methods for try-using Environment Records is defined by the following algorithms:
When the abstract operation NewDeclarativeEnvironment is called with a Lexical Environment as argument _E_ and argument _hint_ the following steps are performed:

◆ createBasedOnSign()
Create a ResultWithValue from a number. If the number is positive the ResultWithValue will have a result of Result::OK and the value will contain the number. If the number is negative the result will be obtained from the negative number (numeric error codes can be found in AAudio.h) and the value will be null.
◆ operator bool()
◆ operator Result()
Implicitly convert to a Result. This enables easy comparison with Result values. Example:
ResultWithValue result = openStream(); if (result == Result::ErrorNoMemory){ // tell user they're out of memory }
◆ operator!()
Quick way to check for an error.
The caller could write something like this: if (!result) { printf("Got error %s\n", convertToText(result.error())); }
- Returns
- true if an error occurred

PS5 price won't be as bad as we thought, if this leak is to be believed
by Vic HoodPS5 price won't be as bad as we thought, if this leak is to be believed
Will the PS5 release date be November 20, 2020?
(Image credit: Djordje Novakov / Shutterstock.com)
We may now know the PS5 price and release date, if a new leak is to be believed.
Twitter user PSErebus recently tweeted several 'leaks' about the PS5 (via LetsGoDigital), but the most interesting was the suggestion that the PS5 release date will be November 20, 2020 in North America and that the PlayStation 5 price will be $499.
What are the details?
We knew the PS5 was due for release in late 2020, so a November 20 release would make sense. As the tweeter points out, this date is five days after the release of PS4, seven years before, 25 days after the 20th anniversary of PlayStation 2 and exactly five weeks before December 25 (AKA Christmas).
Presumably as a launch title for the PS5, the leak also suggests Gran Turismo 7 will release on November 20, 2020.
But what's perhaps most interesting is supposed PS5 cost of $499. The PS4 and PS4 Pro both launched with a price tag of $399, so for the next generation console to only cost $100 more would be a welcome surprise - especially given the specs its boasting.
Whether that's something to do with the potential PS5 cartridge we've seen is up for debate, but Sony has always had a knack for balancing price and power for its console.
As always, it's worth taking this leak with a big pinch of salt. However, this Twitter user previously leaked the correct release date for The Last of Us 2 - so it could be legit.

rpc.nfsd
Section: Maintenance Commands (8)Updated: 7 Aug 2006
Index Return to Main Contents
NAME
rpc.nfsd - NFS server processSYNOPSIS
/usr/sbin/rpc.nfsd [options] nprocDESCRIPTION
The rpc.nfsd program implements the user level part of the NFS service. The main functionality is handled by the nfsd kernel module. The user space program merely specifies what sort of sockets the kernel service should listen on, what NFS versions it should support, and how many kernel threads it should use. The rpc.mountd server provides an ancillary service needed to satisfy mount requests by NFS clients.OPTIONS
- -d or --debug
- enable logging of debugging messages
- -H or --host hostname
- specify a particular hostname (or address) that NFS requests will be accepted on. By default, rpc.nfsd will accept NFS requests on all known network addresses. Note that lockd (which performs file locking services for NFS) may still accept request on all known network addresses. This may change in future releases of the Linux Kernel.
- -p or --port port
- specify a diferent port to listen on for NFS requests. By default, rpc.nfsd will listen on port 2049.
- -N or --no-nfs-version vers
- This option can be used to request that rpc.nfsd does not offer certain versions of NFS. The current version of rpc.nfsd can support both NFS version 2,3 and the newer version 4.
- -s or --syslog
- By default, rpc.nfsd logs error messages (and debug messages, if enabled) to stderr. This option makes rpc.nfsd log these messages to syslog instead. Note that errors encountered during option processing will still be logged to stderr regardless of this option.
- -T or --no-tcp
- Disable rpc.nfsd from accepting TCP connections from clients.
- -U or --no-udp
- Disable rpc.nfsd from accepting UDP connections from clients.
- nproc
-
specify the number of NFS server threads. By default, just one
thread is started. However, for optimum performance several threads
should be used. The actual figure depends on the number of and the work
load created by the NFS clients, but a useful starting point is
8 threads. Effects of modifying that number can be checked using
the
nfsstat(8)
program.
Note that if the NFS server is already running, then the options for
specifying host, port, and protocol will be ignored. The number of
processes given will be the only option considered, and the number of
active
nfsd
processes will be increased or decreased to match this number.
In particular
rpc.nfsd 0
will stop all threads and thus close any open connections.
NOTES
If the program is built with TI-RPC support, it will enable any protocol and address family combinations that are marked visible in the netconfig database.SEE ALSO
rpc.mountd(8), exports(5), exportfs(8), rpc.rquotad(8), nfsstat(8), netconfig(5).AUTHOR

This post provides a basic introduction to R Markdown.1 An R Markdown file contains three essential ingredients – a YAML header to define document-wide settings, chunks of R code, and markdown text. They are designed to be used:
- For communicating to those who want to focus on the conclusions, not the code behind the analysis.
- For collaborating with those who are interested in both the conclusions and how they were reached.
- For capturing the work you do and what you were thinking at the time.
Resources:
- R Markdown Cheat Sheet: a quick reference
- R Markdown Reference: overview of markdown syntx, knitr chunk options, and Pandoc options
- R Markdown: The Definitive Guide: a comprehensive overview of R Markdown
- Git and Github chapter of R Packages: learn about git with R
YAML Header
toc: TRUE
adds a table of contents.toc_float: TRUE
makes the table of contents float as you scross through the document.code_folding
makes code chunks hidden by default but visible with a click.- For a list of options, see
?rmarkdown::html_document
. - Set
parameters
to set values when rendering the report; useful withpwalk()
to re-render with different variables. - Set
bibliography
to a bibliography file to automatically generate citations.
Formatting code chunks
eval = FALSE
prevents code from being evaluated.include = FALSE
runs the code, but doesn’t show the code or results in the final document.echo = FALSE
prevents code, but not results from appearing in the finished file.message = FALSE
orwarning = FALSE
prevents messages or warnings from appearing in the finished file.results = 'hide'
hides printed output, andfig.show = 'hide'
hides plots.fig.show = 'hold'
holds multiple plots from a code chunk, andout.width = '50%'
specifies the width.error = TRUE
causes the render to continue even if code returns an error (for debugging).
Tip: To print fancier-looking tables, surround your code with knitr::kable(..., caption = "Table Title")
or use other packages such as xtable, stargazer, apnder, tables, ascii
.
Tip: Cache code chunks for better performance with the option cache = TRUE
. Use the dependson
option if the chunk needs to be re-run if a dependency is changed, specifying a character vector of every chunk that the cached cunk depends on. Clean the cache with clean_cache()
Tip: Change the code chunk defaults at the beginning of the document – for example, if you are presenting a doc for decision makers, you can turn off the default display of code globally:
Troubleshooting R Markdown
- Restart R, then run all chunks ( Ctrl + Alt + R )
- Check the working directory with
r getwd()
in a chunk. - Set
r error = TRUE
on the chunk causing the problem, then user print()
andr str()
to check settings.
Misc Info - Additional R Markdown Formats
The output format can be set permanently by modifying the YAML header or set once by calling rmarkdown::render()
.
- Basic document types:
pdf_document
,word_document
,github_document
, andhtml_notebook
. - Use
html_notebook
to collaborate; they contain full source code, are viewable in a browser and editable in RStudio. - Use
beamer_presentation
to create a PDF presentation with LaTeX Beamer - Use
flexdashboard::flex_dashboard
for dashboards. - To produce interactivity,
htmlwidgets
produces interactive HTML visualizations in markdowon on the client-side, whileshiny
creates interactivity using R code, but needs a Shiny server to be run online. - Other formats include
bookdown
to write books, orprettydoc
to create nice-looking documents.
-
This post is meant for a person who is looking for a refresher on R Markdown. The content in this post is based on chapters twenty-seven through thirty of R for Data Science by Hadley Wickham & Garrett Grolemund. ⤴
