Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Control pattern.
This pattern splits the view (also called the presentation) into "dumb" templates that are primarily responsible for inserting pre-built data in between HTML tags. The model contains the "smart" domain objects (such as Account, Product, Person, Post) that holds all the business logic and knows how to persist themselves to a database. The controller handles the incoming requests (such as Save New Account, Update Product, Show Post) by manipulating the model and directing data to the view.
In Rails, the model is handled by what‘s called an object-relational mapping layer entitled Active Record. This layer allows you to present the data from database rows as objects and embellish these data objects with business logic methods. You can read more about Active Record in files/vendor/rails/activerecord/README.html.
The controller and view are handled by the Action Pack, which handles both layers by its two parts: Action View and Action Controller. These two layers are bundled in a single package due to their heavy interdependence. This is unlike the relationship between the Active Record and Action Pack that is much more separate. Each of these packages can be used independently outside of Rails. You can read more about Action Pack in files/vendor/rails/actionpack/README.html.

<tt>cd myapp; rails server</tt> (run with --help for options)
"Welcome aboard: You're riding the Rails!"
the following resources handy:
By default, Rails will try to use Mongrel if it‘s installed when started with rails server, otherwise Rails will use WEBrick, the web server that ships with Ruby.
Mongrel is a Ruby-based web server with a C component (which requires compilation) that is suitable for development. If you have Ruby Gems installed, getting up and running with mongrel is as easy as:
<tt>sudo gem install mongrel</tt>.
You can find more info at: mongrel.rubyforge.org
You can alternatively run Rails applications with other Ruby web servers, e.g., Thin, Ebb, and Apache with mod_rails. However, rails server doesn‘t search for or start them.
For production use, often a web/proxy server, e.g., Apache, Nginx, LiteSpeed, Lighttpd, or IIS, is deployed as the front end server with the chosen Ruby web server running in the back end and receiving the proxied requests via one of several protocols (HTTP, CGI, FCGI).
Sometimes your application goes wrong. Fortunately there are a lot of tools that will help you debug it and get it back on the rails.
First area to check is the application log files. Have "tail -f" commands running on the server.log and development.log. Rails will automatically display debugging and runtime information to these files. Debugging info will also be shown in the browser on requests from <IP_ADDRESS>.
You can also log your own messages directly into the log file from your code using the Ruby logger class from inside your controllers. Example:
class WeblogController < ActionController::Base def destroy @weblog = Weblog.find(params[:id]) @weblog.destroy logger.info("#{Time.now} Destroyed Weblog ID ##{@weblog.id}!") end end
The result will be a message in your log file along the lines of:
Mon Oct 08 14:22:29 +1000 2007 Destroyed Weblog ID #1!
More information on how to use the logger is at www.ruby-doc.org/core/
Also, Ruby documentation can be found at www.ruby-lang.org/. There are several books available online as well:
These two books will bring you up to speed on the Ruby language and also on programming in general.
Debugger support is available through the debugger command when you start your Mongrel or WEBrick server with —debugger. This means that you can break out of execution at any point in the code, investigate and change the model, and then, resume execution! You need to install ruby-debug to run the server in debugging mode. With gems, use sudo gem install ruby-debug. Example:
class WeblogController < ActionController::Base def index @posts = Post.find(:all) debugger end end
So the controller will accept the action, run the first line, then present you with a IRB prompt in the server window. Here you can do things like:
>> @posts.inspect => "[#<Post:0x14a6be8 @attributes={"title"=>nil, "body"=>nil, "id"=>"1"}>, #<Post:0x14a6620 @attributes={"title"=>"Rails", "body"=>"Only ten..", "id"=>"2"}>]" >> @posts.first.title = "hello from a debugger" => "hello from a debugger"
…and even better, you can examine how your runtime objects actually work:
>> f = @posts.first => #<Post:0x13630c4 @attributes={"title"=>nil, "body"=>nil, "id"=>"1"}> >> f. Display all 152 possibilities? (y or n)
Finally, when you‘re ready to resume execution, you can enter "cont".
The console is a Ruby shell, which allows you to interact with your application‘s domain model. Here you‘ll have all parts of the application configured, just like it is when the application is running. You can inspect domain models, change values, and save to the database. Starting the script without arguments will launch it in the development environment.
To start the console, run rails console from the application directory.
Options:
To reload your controllers and models after launching the console run reload!
More information about irb can be found at: http://www.rubycentral.com/pickaxe/irb.html
You can go to the command line of your database directly through rails dbconsole. You would be connected to the database with the credentials defined in database.yml. Starting the script without arguments will connect you to the development database. Passing an argument will connect you to a different database, like rails dbconsole production. Currently works for MySQL, PostgreSQL and SQLite 3.
The default directory structure of a generated Ruby on Rails application:
|-- app | |-- controllers | |-- helpers | |-- models | `-- views | `-- layouts |-- config | |-- environments | |-- initializers | `-- locales |-- db |-- doc |-- lib | `-- tasks |-- log |-- public | |-- images | |-- javascripts | `-- stylesheets |-- script | `-- performance |-- test | |-- fixtures | |-- functional | |-- integration | |-- performance | `-- unit |-- tmp | |-- cache | |-- pids | |-- sessions | `-- sockets `-- vendor `-- plugins
app
Holds all the code that's specific to this particular application.
app/controllers
Holds controllers that should be named like weblogs_controller.rb for automated URL mapping. All controllers should descend from ApplicationController which itself descends from ActionController::Base.
app/models
Holds models that should be named like post.rb. Models descend from ActiveRecord::Base by default.
app/views
Holds the template files for the view that should be named like weblogs/index.html.erb for the WeblogsController#index action. All views use eRuby syntax by default.
app/views/layouts
Holds the template files for layouts to be used with views. This models the common header/footer method of wrapping views. In your views, define a layout using the <tt>layout :default</tt> and create a file named default.html.erb. Inside default.html.erb, call <% yield %> to render the view using this layout.
app/helpers
Holds view helpers that should be named like weblogs_helper.rb. These are generated for you automatically when using generators for controllers. Helpers can be used to wrap functionality for your views into methods.
config
Configuration files for the Rails environment, the routing map, the database, and other dependencies.
db
Contains the database schema in schema.rb. db/migrate contains all the sequence of Migrations for your schema.
doc
This directory is where your application documentation will be stored when generated using <tt>rake doc:app</tt>
lib
Application specific libraries. Basically, any kind of custom code that doesn't belong under controllers, models, or helpers. This directory is in the load path.
public
The directory available for the web server. Contains subdirectories for images, stylesheets, and javascripts. Also contains the dispatchers and the default HTML files. This should be set as the DOCUMENT_ROOT of your web server.
script
Helper scripts for automation and generation.
test
Unit and functional tests along with fixtures. When using the rails generate command, template test files will be generated for you and placed in this directory.
vendor
External libraries that the application depends on. Also includes the plugins subdirectory. If the app has frozen rails, those gems also go here, under vendor/rails/. This directory is in the load path.

Reads a Hess (.n3d) CFD panel method geometry file into an AVS/Express Mesh.
module Read_Hess_File < src_file = "rd_hess.cxx", out_src_file = "gen.cxx", out_hdr_file = "gen.h", cxx_hdr_files = "fld/Xfld.h" > { string+IPort2 hess_filename; Field+Space3+OPort2 out_fld; cxxmethod+req update ( .hess_filename +read+req+notify, .out +write ); };
The Read_Hess_File module allows files in the "Hess" file format to be read into AVS/Express. The Hess file format is used by CFD panel methods. It is also very close to the "PANAIR" format that is used by the North-American Aerospace industry. The module takes the geometry from the Hess file and generates a poly-tristrip that is placed into an Express field. The read_hess user macro enhances the module further by including an user interface and by generating a renderable DataObject. Hess format files typically have a ".n3d" extension.
filename
Name of the Tin .N3D file to be read. The parameter is of type string. This is the only input parameter to the Read_Hess_File module.
out_fld
The output field containing field data constructed from the data present in the Hess file.
out_obj
A DataObject created from the data present in the Hess file, that is suitable for direct connection to a viewer.
The low-level Read_Hess_File module is used in the User Macro read_hess. Additionally, the user macro also uses the ReadHessUI UI Macro.
An example application ReadHessEg is provided, which allows a Hess file to be loaded and allows the data to be mirrored around the X,Y and Z axis. Unfortunately no example data files are available for distribution with this module.
xp_comm_proj/rd_hess/hessmods.v contains the V definition of the Read_Hess_File module.
xp_comm_proj/rd_hess/hessmacs.v contains the V definitions of the ReadHessUI User Interface Macro, the read_hess User macro and the ReadHessEg example application.
The low-level ReadHessMods library containing the module Read_Hess_File does not specify a process. By default the express process will be used.

Main syntax:
$("selector").xzoom({options});
For example, initialize with 1 class name:
$(".xzoom").xzoom();
In this case xZoom will take first image of the class ".xzoom" as main source image to provide zoom functionality on it. Other images with the same class will be used as thumbnails.
Initialize with 2 and more class names:
$(".xzoom, .xzoom-gallery").xzoom();
In this case xZoom will take only first image of the class ".xzoom" as main source image, then will ignore all other images of the class ".xzoom", and starting from second class ".xzoom-gallery" it will use all of the images as thumbnails.
It is possible also to use the ID for the main source image in initialization, like:
$("#main_image, .xzoom-gallery").xzoom();
The HTML structure of all zoom images, must be the next:

Note: all thumbnails must be wrapped by 'a' tag, where 'href' attribute contains the path to original big image.
Here is list of all possible options and their description:
| Property | Default | Description |
|---|---|---|
| position | right | Position of zoom output window, one of the next properties is available "top", "left", "right", "bottom", "inside", "lens", "#ID". |
| mposition | inside | Position of zoom output window in adaptive mode (i.e. for mobile devices) available properties: "inside", "fullscreen". |
| rootOutput | true | In the HTML structure, this option gives an ability to output xzoom element, to the end of the document body or relative to the parent element of main source image. |
| Xoffset | 0 | Zoom output window horizontal offset in pixels from output base position. |
| Yoffset | 0 | Zoom output window vertical offset in pixels from output base position. |
| fadeIn | true | Fade in effect, when zoom is opening. |
| fadeTrans | true | Fade transition effect, when switching images by clicking on thumbnails. |
| fadeOut | false | Fade out effect, when zoom is closing. |
| smoothZoomMove | 3 | Smooth move effect of the big zoomed image in the zoom output window. The higher value will make movement smoother. |
| smoothLensMove | 1 | Smooth move effect of lens. |
| smoothScale | 6 | Smooth move effect of scale. |
| defaultScale | 0 | You can setup default scale value of zoom on opening, from -1 to 1. Where -1 means -100%, and 1 means 100% of lens scale. |
| scroll | true | Scale on mouse scroll. |
| tint | false | Tint color. Color must be provided in format like "#color". We are not recommend you to use named css colors. |
| tintOpacity | 0.5 | Tint opacity from 0 to 1. |
| lens | false | Lens color. Color must be provided in format like "#color". We are not recommend you to use named css colors. |
| lensOpacity | 0.5 | Lens opacity from 0 to 1. |
| lensShape | box | Lens shape "box" or "circle". |
| lensCollision | true | Lens will collide and not go out of main image borders. This option is always false for position "lens". |
| lensReverse | false | When selected position "inside" and this option is set to true, the lens direction of moving will be reversed. |
| zoomWidth | auto | Custom width of zoom window in pixels. |
| zoomHeight | auto | Custom height of zoom window in pixels. |
| sourceClass | xzoom-source | Class name for source "div" container. |
| loadingClass | xzoom-loading | Class name for loading "div" container that appear before zoom opens, when image is still loading. |
| lensClass | xzoom-lens | Class name for lens "div". |
| zoomClass | xzoom-preview | Class name for zoom window(div). |
| activeClass | xactive | Class name that will be added to active thumbnail image. |
| hover | false | With this option you can make a selection action on thumbnail by hover mouse point on it. |
| adaptive | true | Adaptive functionality. |
| adaptiveReverse | false | Same as lensReverse, but only available when adaptive is true. |
| title | false | Output title/caption of the image, in the zoom output window. |
| titleClass | xzoom-caption | Class name for caption "div" container. |
| bg | false | Zoom image output as background, works only when position is set to "lens". |
$(".xzoom").xzoom({option1: value, option2: value, ...});
For the main source image tag:
xoriginal
- the path to the big image, that will be used as zoomed image in zoom.
xpreview
- optional, but when it is set up, this attribute used as the medium preview image, while the src attribute in this case will be used as the small thumbnail image. If this attribute is not set up, then src attribute will be used as the medium preview image.
xtitle
- text string that will be used as caption and will be shown in zoom output window inside "div" container with titleClass. If this attribute is not used then xZoom will use regular title attribute of the image.
Getting an instance:
var instance = $("selector").xzoom({options});
$("selector").xzoom({options});
var instance = $("selector").data('xzoom');
After you got an instance, you are able to use API functions.
List of available methods:
xappend(jQuery_object)
- this function can add new thumbnail to current xZoom instance. It will take as parameter 1, object that must be an image and passed as jQuery object.
gallery()
- this function can be used for integration with gallery plugins, like "FancyBox" or "Magnific Popup", it returns an object with the next properties:
index
- current selected thumbnail. Starting from 0.
ogallery
- array of paths to original big images.
cgallery
- array of paths to original big images. Order begins from current index.
//Example: Integration with FancyBox plugin
$('#main_image').bind('click', function() {
var xzoom = $(this).data('xzoom');
xzoom.closezoom();
$.fancybox.open(xzoom.gallery().cgallery, {padding: 0, helpers: {overlay: {locked: false}}});
event.preventDefault();
});
//Example: Integration with "Magnific Popup" plugin
$('#main_image').bind('click', function() {
var xzoom = $(this).data('xzoom');
xzoom.closezoom();
var gallery = xzoom.gallery().cgallery;
var i, images = new Array();
for (i in gallery) {
images[i] = {src: gallery[i]};
}
$.magnificPopup.open({items: images, type:'image', gallery: {enabled: true}});
event.preventDefault();
});
You are able to rewrite event functions that xzoom uses on some specific steps of working, to have more deep control and expand functionality as you want.
instance.eventopen(element)
Function that is called on initialization step, that is binding an event "mouseenter" to the passed jQuery object "element" which is originnaly a main source image. And giving a function that need to be called when event will be triggered "instance.openzoom".
//Example
instance.eventopen = function(element) {
element.bind('mouseenter', instance.openzoom);
}
Note: usually there is no need to change this function at all, but it is just present as optional feature. Because you just can use main source image via jQuery to bind to it any event and instance function "instance.openzoom" to open xZoom when event fired.
instance.eventleave(element)
Function that is called on the step when it is needed to bind an event to the element on which the leaving will be tracked.
//Example
instance.eventleave = function(element) {
element.bind('mouseleave', instance.closezoom);
}
instance.eventmove(element)
Function that is called on the step when it is needed to bind an event to the element on which the moving will be tracked.
//Example
instance.eventmove = function(element) {
element.bind('mousemove', instance.movezoom);
}
instance.eventscroll(element)
Function that is called on the step when it is needed to bind an event to the element on which the scrolling for scale will be tracked.
//Example
instance.eventscroll = function(element) {
element.bind('mousewheel DOMMouseScroll', instance.xscroll);
}
instance.eventclick(element)
Function that is called on the step when it is needed to bind an event to the element on which the click will be tracked.
//Example
instance.eventclick = function(element) {
element.bind('click', function(event) {
$('#main_image').trigger('click');
});
}
instance.openzoom(event)
Function to open zoom, uses event.pageX and event.pageY as start location of lens.
instance.closezoom()
Has no parameters, and simply closing the zoom.
instance.movezoom(event)
This function also uses event.pageX and event.pageY to be able to provide movement of lens on the zoom.
instance.xscroll(event)
This function is adapted for "mousewheel", "DOMMouseScroll" events and tested, and works fine on all major browsers. But if you are using some custom events where you will call this function directly then you can use event.xdelta as delta with value 0 or 1 to tell the direction of scaling by 5% from each call, or event.xscale for exact scale with value from -1 to 1 (which means -100% to 100%) to set up exact scale of the zoom as you need.
instance.eventunbind()
Function that will delete original instance.event* functions by replacing them with blank functions and unbind default events on objects. It can help you to clear default mouse binding events that xzoom already setup.
instance.eventdefault()
Function that will restore original instance.event* functions.
.xzoom-source img, .xzoom-preview img, .xzoom-lens img {
display: block;
max-width: none;
max-height: none;
-webkit-transition: none;
-moz-transition: none;
-o-transition: none;
transition: none;
}
Also for this case we created an option rootOutput
, so you can take a control where inside html you want xZoom elements to be output. To the end of body
tag or relative to the parent of main source image.

THE FULL MONTY (R)
Directed by Peter Cattaneo Running Time: 90 minutes Originally Released: August 13, 1997
Reviewed by E. Benjamin Kelsey
* * * (out of four)
How many of us would become strippers? For those of us who wouldn't, is it a moral reason, or purely a lack of confidence? That's probably not a fair question, and for a lot of us, it could very well be for neither of those reasons. As you watch THE FULL MONTY, however, you may begin asking yourself these kinds of questions. Would you be willing to grin and bare it to bring in some much needed dough?
In case you haven't guessed, THE FULL MONTY is about stripping, but STRIPTEASE it ain't. It's actually quite a charming comedy that uses its ideas with a great deal of tact and sophistication. It is the story of six out-of-work, out-of-shape blue collar Brits whose recent job losses have left the boys penniless, but not without need. What to do? It hits our main character Gaz (Robert Carlyle) as he notices the large crowds of women who pour into a local male strip club on a regular basis. It seems that simple: take it off and bring in the cash.
Eventually, Gaz is able to convince his friends to join him in starting their own exotic dance routine despite their initial reluctance. These include the overweight, confidence-lacking Dave (Mark Addy), the uptight, overly-officious Gerald (Tom Wilkinson), the once suicidal Lomper (Steve Huison), and two additional fellows who gain their place among the group by audition: Horse (Paul Barber), an older gentlemen chock full of graceless energy, and Guy (Hugo Speer), a young well-endowed looker who compares himself to Cary Grant.
When the sextet is complete, we're given a hefty dose of physical comedy. We watch the bumbling middle-aged men choreograph pseudo-sexy dance numbers, all the while proving why none of them were strippers in the first place.
The movie actually ends on opening night; a hilarious applause worthy ending I might add. It's sure to leave nothing short of a big smile on your face as you leave the theater. With the subject matter, you might not expect THE FULLY MONTY to be such a feel-good, almost inspiring film, but it surprisingly turns out that way. The amount of light, touching drama also comes as a nice surprise, never feeling off-balance from the otherwise highly upbeat moments of the film. There's a lot more to this movie than you might think in other words, and the ensemble cast couldn't be better. Each character is completely individual, interesting, funny, and most importantly, real.
THE FULL MONTY is never offensive, a very impressive attribute since its subject matter alone could've easily fallen prey to tastelessness. It's one of those movies that is best described as a solid piece of entertainment, perfect for a great night on the town, or as a Saturday night movie rental.  And, pun heavily intended, when it's all said and done, you'll be smiling from cheek to cheek.

One of the most important thing that is happening in Forge 2011 is the amount of work we're doing related to usability, focusing all our efforts in tree projects:
- Network Management
- Power Management
- Places View
In all three of them we used more or less the same methodology and because of that we have been able to reuse some work we did for Network Management into the rest of the projects; Let me introduce you to Penny and Amy.
After we defined the vision of Network Management (basically how and in what we think NM should help users) we needed to decide the kind of users we're targeting, for doing that we defined two personas each in one corner case, one is computer science profesional and the other one is only interested in watching lolcats :p
Penny: She is only interested in "being" online not into "get" online, meaning that she wants stuff to work out of the box or at least without bothering her alot.
Amy: She is a sysadmin, she wants to be able to configure all the possible options out there .
(Click on the name to read the full persona description).
So, once we got our two personas defined and the main target selected (Penny) the next step was to list a few
places where each persona will use Network Management, for example: "Penny's home, train, park...". Finally we went through all possibilities imagining what our personas will
want to do in that location.
The funny thing about this is that we end up thinking like our personas will do, trying to make our best so Penny will be happy while Amy won't be bothered. And you want to know another funny thing? we discovered that by making Penny's life easier we were making Amy's easier as well, no matter if Amy is an "advanced user".
I can't talk by others, but I will think as Penny from now on when I'm designing workspace stuff.


| e | Pronounced like the first part of the "ay"-sound in "say", i.e. without the final "y"-sound. The "e" in "get" is also a fair approximation. The German "ä" and the Danish "æ" are better approximations. |
|---|---|
| ei/ee | Pronounced as a Japanese "e" (see above), but twice as long in duration. Note that in hiragana text this long vowel often occurs when a syllable (e.g. "ke") is followed by an "i". In such cases the "i" is misleading and should not be pronounced as an "i" - it only serves to prolong the "e" sound. |
| i | Pronounced like the "ee" in "feet", but short in duration. It is NOT pronounced like the "i" in "him". Often the "i" is not pronounced in the syllable "shi" when it is followed by another syllable. |
| o | Pronounced like the first part of the "o"-sound in "old", i.e. without the final "u"-sound. The Danish "å" is also a good approximation. |
| ou/oo | Pronounced as a Japanese "o" (see above), but twice as long in duration. Note that in hiragana text this long vowel often occurs when a syllable (e.g. "ko") is followed by a "u". In such cases the "u" is misleading and should not be pronounced as a "u" - it only serves to prolong the "o" sound. |
| g |
Pronounced like the "g" in "get" when it occurs at the beginning of words. Pronounced like the "ng" in "sing" in all other cases. Some people always pronounce it like the "g" in "get". |
| n |
Pronounced like "n" at the beginning of syllables,
or when followed by any of the consonants ch, d, j, n, r, t, z, and sometimes s(h)
(even when these consonants belong to the next word) -
note that these consonants are all produced with the tip of the tongue (except s(h)). Pronounced like "m" when followed by m, b, or p (these consonants are all produced with the lips). Pronounced like the "ng" in "sing" in all other cases. |
| r | Pronounced almost like the "rd" in "weirdo" (with an American-style "r"). |
| z |
Pronounced like "dz" at the beginning of words. Pronounced like "z" in all other cases. |


TempleMetrics: Estimating Conditional Distributions
Estimates conditional distributions and conditional quantiles. The versions of the methods in this package are primarily for use in multiple step procedures where the first step is to estimate a conditional distribution. In particular, there are functions for implementing distribution regression, quantile regression, and versions of local linear distribution regression; all in a unified framework. Distribution regression provides a way to flexibly model the distribution of some outcome Y conditional on covariates X without imposing parametric assumptions on the conditional distribution but providing more structure than fully nonparametric estimation (See Foresi and Peracchi (1995) <doi:10.2307/2291056> and Chernozhukov, Fernandez-Val, and Melly (2013) <doi:10.3982/ECTA10582>).

On the previous post, we finished implementing a drawer but we didn't have true navigation functionality. The drawer simply changed the button that the user was able to click. In this post, we will use Transitions.
We will separate our app into three parts. Let's start with the Notification
section

back

Notification

<button id="btn-notify"> Notify Me!</button>

Notice that the header contains a back button with the a#btn-notification-back
. The content of the page is under div role="main"
.
The Alarm
section will be very similar

back

Alarm

<button id="btn-notify-wait"> Notify Me! (Wait 5s)</button>

It has the same structure as section#notification
.
The main content section will be similar as to what we had before but it's going to be wrapped in section#index
. The reason why will be explained in the next section.

<menu type="toolbar"> Done </menu>

Demos

Notification

Alarm

hide sidebar
show sidebar

API Showcase

 Welcome to API Showcase.
Open the drawer to see all the demos

The layout of the page is as follows. Every section that has the property data-position="right"
will be placed off screen to the right. We accomplish this with the following CSS
[data-position="right"] {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
transform: translateX(100%);
-webkit-transform: translateX(100%);
z-index: 15;
z-index: 100; /* -> drawer */
}
The sections with data-position="current"
will be place in the center of the page, where the user can interact with them (hence the value current
). To navigate from one section to the next, we simply shift the current
section and the next section to the left. This is the reason why we had to wrap the sidebar section and section#drawer
in the section#index
, the whole middle section has to move or else they end up on top of each other.
Building blocks provides the following transitions to help us make this navigation possible
currentToLeft
: moves the current section off to the leftcurrentToRight
: same as above but to the rightrightToCurrent
: moves the off-screen section towards the centerleftToCurrent
: same as above but from the left We can use currentToLeft
and rightToCurrent
to navigate from the main section to another. Then, we can use leftToCurrent
and currentToRight
to bring things back to how they originally were.
We can easily use these transitions by changing an elements class, and making CSS rules based on these classes. The classes can be left
, current
, and right
. Intuitively, they move a section to the left, to the right, or back to the middle.
Therefore, when we click a navigation link in our drawer, we will set the class of the current element to left
and the off-screen section to current
document.querySelector('#nav-notify').addEventListener ('click', function () {
document.querySelector('#notification').className = 'current';
document.querySelector('[data-position="current"]').className = 'left';
});
document.querySelector('#nav-alarm').addEventListener ('click', function () {
document.querySelector('#alarm').className = 'current';
document.querySelector('[data-position="current"]').className = 'left';
});
To each section has a btn-*-back
button, so we can reverse the actions above with the following
document.querySelector('#btn-notification-back').addEventListener ('click', function () {
document.querySelector('#notification').className = 'right';
document.querySelector('[data-position="current"]').className = 'current';
});
document.querySelector('#btn-alarm-back').addEventListener ('click', function () {
document.querySelector('#alarm').className = 'right';
document.querySelector('[data-position="current"]').className = 'current';
});
Finally, the following CSS will tie up the animations to the classes
[data-position="right"].current {
animation: rightToCurrent 0.4s forwards;
-webkit-animation: rightToCurrent 0.4s forwards;
}
[data-position="right"].right {
animation: currentToRight 0.4s forwards;
-webkit-animation: currentToRight 0.4s forwards;
}
[data-position="current"].left {
animation: currentToLeft 0.4s forwards;
-webkit-animation: currentToLeft 0.4s forwards;
}
[data-position="current"].current {
animation: leftToCurrent 0.4s forwards;
-webkit-animation: leftToCurrent 0.4s forwards;
}
As always, feel free to try the demo and examine the source code.


The search function is used to access the machine learning model for a prediction of the input values. The request body parameters are expected to be in a json payload

Handling blocking operations in Akka HTTP
Sometimes it is difficult to avoid performing the blocking operations and there are good chances that the blocking is done inside a Future execution, which may lead to problems. It is important to handle the blocking operations correctly.
Problem
Using context.dispatcher
context.dispatcher()
as the dispatcher on which the blocking Future executes can be a problem - the same dispatcher is used by the routing infrastructure to actually handle the incoming requests.
If all of the available threads are blocked, the routing infrastructure will end up starving. Therefore, routing infrastructure should not be blocked. Instead, a dedicated dispatcher for blocking operations should be used.
Blocking APIs should also be avoided if possible. Try to find or build Reactive APIs, such that blocking is minimised, or moved over to dedicated dispatchers.
Often when integrating with existing libraries or systems it is not possible to avoid blocking APIs. The following solution explains how to handle blocking operations properly.
Note that the same hints apply to managing blocking operations anywhere in Akka, including in Actors etc.
In the thread state diagrams below the colours have the following meaning:
- Turquoise - Sleeping state
- Orange - Waiting state
- Green - Runnable state
The thread information was recorded using the YourKit profiler, however any good JVM profiler has this feature (including the free and bundled with the Oracle JDK VisualVM, as well as Oracle Flight Recorder).
Problem example: blocking the default dispatcher
- Scala
-
source
// BAD (due to blocking in Future, on default dispatcher) implicit val defaultDispatcher = system.dispatcher val routes: Route = post { complete { Future { // uses defaultDispatcher Thread.sleep(5000) // will block on default dispatcher, System.currentTimeMillis().toString // Starving the routing infrastructure } } }
- Java
-
source
import static akka.http.javadsl.server.Directives.completeWithFuture; import static akka.http.javadsl.server.Directives.post; // BAD (due to blocking in Future, on default dispatcher) final Route routes = post( () -> completeWithFuture(CompletableFuture.supplyAsync(() -> { // uses defaultDispatcher try { Thread.sleep(5000L); // will block on default dispatcher, } catch (InterruptedException e) { } return HttpResponse.create() // Starving the routing infrastructure .withEntity(Long.toString(System.currentTimeMillis())); })) );
Here the app is exposed to a load of continuous GET requests and large numbers of akka.actor.default-dispatcher threads are handling requests. The orange portion of the thread shows that it is idle. Idle threads are fine - they’re ready to accept new work. However, large amounts of Turquoise (sleeping) threads are very bad!
After some time, the app is exposed to the load of POST requests, which will block these threads.
Since we’re using the Java CompletableFuture
in this example, the blocking will happen on its default pool which is the global ForkJoinPool.commonPool()
. With Scala Futures the in-scope provided dispatcher would be used. Both these dispatchers are ForkJoin pools by default, and are not best suited for blocking operations.
For example, the above screenshot shows an Akka FJP dispatchers threads, named “default-akka.default-dispatcher2,3,4
” going into the blocking state, after having been idle. It can be observed that the number of new threads increases, “default-akka.actor.default-dispatcher 18,19,20,...
” however they go to sleep state immediately, thus wasting the resources. The same happens to the global ForkJoinPool
ForkJoinPool
when using Java Futures.
The number of such new threads depends on the default dispatcher configuration, but it will likely not exceed 50. Since many POST requests are being processed, the entire thread pool is starved. The blocking operations dominate such that the routing infra has no thread available to handle the other requests.
In essence, the Thread.sleep
Thread.sleep()
operation has dominated all threads and caused anything executing on the default dispatcher to starve for resources (including any Actors that you have not configured an explicit dispatcher for).
Solution: Dedicated dispatcher for blocking operations
In application.conf
, the dispatcher dedicated to blocking behaviour should be configured as follows:
my-blocking-dispatcher {
type = Dispatcher
executor = "thread-pool-executor"
thread-pool-executor {
fixed-pool-size = 16
}
throughput = 1
}
There are many dispatcher options available which can be found in Dispatchers.
Here thread-pool-executor
is used, which has a hardcoded limit of threads. It keeps a set number of threads available that allow for safe isolation of the blocking operations. The size settings should depend on the app’s functionality and the number of cores the server has.
Whenever blocking has to be done, use the above configured dispatcher instead of the default one:
- Scala
-
source
// GOOD (the blocking is now isolated onto a dedicated dispatcher): implicit val blockingDispatcher = system.dispatchers.lookup("my-blocking-dispatcher") val routes: Route = post { complete { Future { // uses the good "blocking dispatcher" that we configured, // instead of the default dispatcher to isolate the blocking. Thread.sleep(5000) System.currentTimeMillis().toString } } }
- Java
-
source
import static akka.http.javadsl.server.Directives.completeWithFuture; import static akka.http.javadsl.server.Directives.post; // GOOD (the blocking is now isolated onto a dedicated dispatcher): final Route routes = post(() -> { final MessageDispatcher dispatcher = system.dispatchers().lookup("my-blocking-dispatcher"); return completeWithFuture(CompletableFuture.supplyAsync(() -> { try { Thread.sleep(5000L); } catch (InterruptedException e) { } return HttpResponse.create() .withEntity(Long.toString(System.currentTimeMillis())); }, dispatcher // uses the good "blocking dispatcher" that we // configured, instead of the default dispatcher to isolate the blocking. )); });
This forces the app to use the same load, initially normal requests and then the blocking requests. The thread pool behaviour is shown in the figure.
Initially, the normal requests are easily handled by the default dispatcher - the green lines, which represent the actual execution.
When blocking operations are issued, the my-blocking-dispatcher
starts up to the number of configured threads. It handles sleeping. After a certain period of nothing happening to the threads, it shuts them down.
If another bunch of operations have to be done, the pool will start new threads that will take care of putting them into sleep state, but the threads are not wasted.
In this case, the throughput of the normal GET requests was not impacted - they were still served on the default dispatcher.
This is the recommended way of dealing with any kind of blocking in reactive applications. It is referred to as “bulkheading” or “isolating” the bad behaving parts of an app. In this case, bad behaviour of blocking operations.
There is good documentation available in Akka docs section, Blocking needs careful management.

[gecode-users] how to use the bab() function
Guido Tack
tack at gecode.org
Wed Dec 4 07:38:22 CET 2013
You can use the Timer class in Support, it works something like this:
Support::Timer timer;
timer.start();
SendMostMoney* m = new SendMostMoney(opt);
if (SendMostMoney* s = bab(m)) {
s->print(); delete s; //Or whatever
}
cout << t.stop() / 1000.0 << " seconds";
Cheers,
Guido

Best forex trading apps of 2019: trade and invest on your Android or iPhone
by Nicholas FearnBest forex trading apps of 2019: trade and invest on your Android or iPhone
Apps to help you make profitable currency trades
(Image credit: Pixabay)
In today’s interconnected world, the foreign exchange market plays an important role in daily business. It’s a global, decentralized environment where financial institutions and businesses can trade currencies.
According to research from the Bank for International Settlements, foreign exchange trading generates an estimated $5.3 trillion daily - making it larger than other financial markets. Often, it’s dominated by large international banks and corporations, which work around the clock to trade and convert international currencies.
Forex trading also underpins international trade and investments. For instance, if American companies want to import goods from a country in Europe, they’ll most likely need to complete transactions in euros. Through forex, these firms can exchange dollars for euros quickly and easily.
As well as enabling trade between countries, forex trading is a lucrative investment opportunity. Every day, companies and investors make billions by purchasing and trading currencies. However, it does take a significant amount of experience and skills to make lucrative forex trades.
That’s where forex trading software comes into the picture, automating this common business practice. Essentially, it ploughs through the market for the best currency trading opportunities. And in this article, we’ve picked out the best forex trading apps around.

5. TD Ameritrade
One of America's biggest trading platforms
+ Good educational materials
+ Wide range of investment products
+ Good for beginners
- Can be cumbersome for Forex only
TD Ameritrade is one of America's biggest and more established trading platforms, and offers a wide range of investment vehicles for trading, not just forex.
However, where it really excels is through its focus on trying to educate forex traders to help reduce the chances of them losing money. It does this through its thinkorswim platform, which provides introductory materials from the
National Futures Association, which regulate futures brokers. The information is presented in a clear and easy-to-read way, and it really does underline the risks that need to be considered.
So if you're new to currency trading, you could feel better prepared and eased into managing not just trades but risk with more confidence, rather than rushing into dangerous leverages that can lose you money fast.
But while that's a big plus for TD Ameritrade, it is a wide platform that covers a comprehensive range of trading products, not least stocks, futures, and options. So if you're looking to focus only on forex you may find the platform sometimes clunky by comparison to dedicated forex trading platforms, especially when it comes to comparing currency pairs.
Even still, the introductory and supporting materials are worth getting to grips with, and if you want to get involved with more than currency trading you're in an ideal place to expand your investment strategy into other products.

| GETPAGESIZE(2) | Linux Programmer's Manual | GETPAGESIZE(2) |
int getpagesize(void);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
getpagesize():
_DEFAULT_SOURCE || ! (_POSIX_C_SOURCE >= 200112L)
_BSD_SOURCE || ! (_POSIX_C_SOURCE >= 200112L)
#include <unistd.h> long sz = sysconf(_SC_PAGESIZE);
(Most systems allow the synonym _SC_PAGE_SIZE for _SC_PAGESIZE.)
Whether getpagesize() is present as a Linux system call depends on the architecture. If it is, it returns the kernel symbol PAGE_SIZE, whose value depends on the architecture and machine model. Generally, one uses binaries that are dependent on the architecture but not on the machine model, in order to have a single binary distribution per architecture. This means that a user program should not find PAGE_SIZE at compile time from a header file, but use an actual system call, at least for those architectures (like sun4) where this dependency exists. Here glibc 2.0 fails because its getpagesize() returns a statically derived value, and does not use a system call. Things are OK in glibc 2.1.

There are three whole lemons used in the cake, icing and decoration so the flavour is incredibly intense and delicious.
Equipment and preparation: you will need 2x 20cm/8in round sponge tins, greased and base lined with baking parchment.
For the decoration, using a zester, peel long strips of lemon rind. If you haven’t got a zester, thinly peel the lemon, then cut into fine strips. Set aside the remaining lemon.
Place the peel in a saucepan, cover with boiling water and half the caster sugar and boil for one minute. Drain and pat dry, then put onto non-stick parchment paper. Scatter over the remaining sugar and toss to coat the lemon peel. Arrange on the non-stick baking parchment and leave in a warm place to dry out for as long as possible or overnight, until crisp. If you are in a hurry, dry out in a low oven 110C/225F/Gas ¼ for 30 minutes.
Cut the zested lemon in half and squeeze the juice. Set it aside to make the icing.
For the cake, place the two whole (or one large) lemons in a small saucepan, cover with water, bring to the boil and simmer for 20 minutes, or until very soft and tender. Drain, cut the lemons in half and remove any pips.
Preheat the oven to 180C/350F/Gas 4 (160C fan).
Place the lemons, including the skin, in a food processor and process until smoothish, but still with some chunky bits. Put the mixture in a small bowl.
Add all the remaining cake ingredients into the food processor and blend until smooth. Lift out the blade and stir in just over half of the lemon pulp. Set the rest aside.
Divide the mixture evenly between the two tins and bake for 30 minutes, or until golden-brown and just shrinking from the edge of the tins.
Leave to cool for five minutes, then turn the cakes out, peel off the baking parchment and leave to finish cooling on a wire rack.
For the lemon filling, blend the butter and icing sugar in a food processor until smooth and creamy. Add the mascarpone, blend again and then add the lemon pulp and blend until just mixed.
Cut both cakes in half so that you have four layers. Spread the lemon cream evenly between the layers, stacking them on top of each other.
Mix the fondant icing sugar with 1-2 tbsp lemon juice (from the lemon used to make the candied zest decoration) to make a thick pouring consistency. Pour the icing over the top of the cake allowing it to drizzle down. Sprinkle the candied lemon rind on top.

The Looker JavaScript Embed SDK is designed to facilitate using Looker embedded content in your web application. The goal is to make communication between a host website and one or more embedded dashboards, looks or explores easier and more reliable.
A typical setup might look like this. In this case, a dashboard with an id of 11
is created inside a DOM element with the id dashboard
. The dashboard:run:start
and dashboard:run:complete
events are used to update the state of the embedding window's UI, and a button with an id of run
is scripted to send a dashboard:run
message to the dashboard.
LookerEmbedSDK.init('looker.example.com:443', '/auth')
const setupDashboard = (dashboard) => {
document.querySelector('#run').addEventListener('click', () => {
dashboard.send('dashboard:run')
})
}
LookerEmbedSDK.createDashboardWithId(11)
.appendTo('#dashboard')
.on('dashboard:run:start',
() => updateState('#dashboard-state', 'Running')
)
.on('dashboard:run:complete',
() => updateState('#dashboard-state', 'Done')
)
.build()
.connect()
.then(setupDashboard)
.catch((error: Error) => {
console.error('An unexpected error occurred', error)
})
A more complete example can be found here. Detailed instructions on how to use it are here.
The Looker Embed SDK uses a fluent interface pattern. The construction of the embedded content is broken into two phases, building and connecting.
First initialize the SDK with address of your Looker server and, optionally, the endpoint on your server that will perform authentication. These are used by all the embedded content.
LookerEmbedSDK.init('looker.example.com:443', '/auth')
Then the embedded content is built using a series of steps to define its parameters. Some if these parameters are optional, and some are mandatory.
The process starts with creating the builder with an id
, or a url
created by the processed described here:
LookerEmbedSDK.createDashboardWithId(id)
or
LookerEmbedSDK.createDashboardWithUrl(url)
You can then add additional attributes to the builder to complete your setup:
.appendTo('#dashboard')
You can add event handlers:
.on('dashboard:run:start',
() => updateState('#dashboard-state', 'Running')
)
.on('dashboard:run:complete',
() => updateState('#dashboard-state', 'Done')
)
You finish by building the embedded element:
.build()
If you want to send and receive messages to the embedded element you need to call connect()
which returns a Promise that resolves to the communication interface of the given element:
.connect()
.then(setupDashboard)
.catch(console.error)
The main documentation for Looker SSO embed URLs is here. The only difference when creating URLs for the SDK is that you will need to add an sdk=2
parameter to the Embed URL alongside other parameters like filters and the embed_domain
parameter. This parameter allows Looker to identify that the SDK is present and can take advantage of additional features provided by the SDK.
/embed/looks/4?embed_domain=https://mywebsite.com => /embed/looks/4?embed_domain=https://mywebsite.com&sdk=2
The SDK cannot add this parameter itself because it part of the signed SSO URL.
Because the embed secret needs to be carefully guarded, embed SSO URLs cannot be created in the browser. To make the process easier and secure, you can instead do the following:
Implement a URL signing function in your web server. The server should return a signed URL using one of the processes documented in the Looker Embed SSO Examples Github repository.
Pass the embed SSO URL to that signing endpoint in the embed SDK. The location of the endpoint is specified by the authUrl
parameter in LookerEmbedSDK.init()
.
If specified, whenever an embed element is created using just an ID, its embed URL is generated using the type of the element, the provided Looker host, and any provided parameters. For example:
LookerEmbedSDK.init('looker.example.com:443', '/looker_auth')
LookerEmbedSDK.createcreateDashboardWithId(11)
.build()
This will call the /looker_auth endpoint and return a signed SSO URL that can be used to create the embedded content:
src=https://looker.example.com:443/embed/dashboards/11?sdk=2&embed_host=https://yourhost.example.com
A signing helper method createSignedUrl()
is provided in
server_utils/auth_utils.ts. Its usage is as follows:
import { createSignedUrl } from './auth_utils'
app.get('/looker_auth', function(req, res) {
// Authenticate the request is from a valid user here
const src = req.query.src;
const host = 'http://looker.example.com:443'
const secret = YOUR_EMBED_SECRET
const user = authenticatedUser
const url = createSignedUrl(src, user, host, secret);
res.json({ url });
});
The user
data structure is
interface LookerEmbedUser {
external_user_id: string
first_name?: string
last_name?: string
session_length: number
force_logout_login?: boolean,
permissions: LookerUserPermission[]
models: string[]
group_ids?: number[]
external_group_id?: string
user_attributes?: {[key: string]: any}
access_filters: {[key: string]: any}
}
There is a simple demo provided, but because of Looker's attention to security, it requires a bit of setup. It also requires Looker's "Embed Secret". Because the embed secret can grant access to all of your data:
Do not share your secret with anyone you do not want to have complete access to your instance.
Do not reset your secret if you already are using it in another context.
Your code should never store the secret in the web browser.
(This is documented in more detail here)
Provide your embed secret to the server. You can do this a couple ways.
LOOKER_EMBED_SECRET
in your shell environment..env
in the root of the sdk directory. Add a line to that file: LOOKER_EMBED_SECRET="YourLookerSecret"
Provide your Looker instance host address to the server by either:
LOOKER_EMBED_HOST
in your shell environment.LOOKER_EMBED_HOST="yourinstance.looker.com:yourport"
to the .env
file.Edit the demo/demo_config.ts
file to be appropriate for the pages you want to embed.
// The address of your Looker instance. Required.
export const lookerHost = 'self-signed.looker.com:9999'
// A dashboard that the user can see. Set to 0 to disable dashboard.

You can imagine how surprised I was when I found in 2013 summer that there is no jQuery module yet which wraps document.createElement()!
So, I've made it, here is the long-waited jQuery plugin called:
Usage:
$("#container").append( $.create("div").addClass("box").html("Hello, world!") );
$.create("tr","row-8"); // second parm: ID
I know, it's not the most useful plugin of the jQuery world, but I think $.create("div") looks better than elm = $("

") or elm = $("
"). And it's also free! And lightweight!


Interested in volunteering? Awesome! There are many ways to get involved, especially around the holiday season when we prepare our food baskets. Stop on by during our open hours and ask!

Error handling
Note that unlike C or C11, C++ provides native support for exceptions. Hence the C++ API adopts the C++ style of handling and reporting errors to its caller, using exceptions. Unlike the normal C convention of returning integer values (0 for success and negative values in case of failure), it uses C++ exceptions to indicate error scenarios. All APIs return the expected output on success (or void if no output is returned), and throw an exception on error. Instead of checking the return value for errors as in C, the caller should use try-catch blocks for handling errors.
The implementation defines a set of exception classes, which
are derived from C++ standard exception class to categorize various
types of failures, like Runtime
, Allocator
, Data-path
, etc. It also
defines a list of individual error numbers to identify a specific
error. The exception object received by the caller in case of an
error will contain a specific error number and an appropriate error
message string. The application can retrieve this information using
member functions, fam_error()
and fam_error_msg()/what()
and take
any necessary action. The currently defined exceptions (and
exception numbers) are defined in Table 1 and Table 2
| Fam Exception Class | Description |
|---|---|
| Fam_Exception | This is the base exception class for all FAM exceptions. |
| Fam_InvalidOption_Exception | For invalid options or arguments for FAM APIs. |
| Fam_Timeout_Exception | Retry or Timeout limit for blocking APIs. |
| Fam_Datapath_Exception | Indicate data path errors. |
| Fam_Allocator_Exception | Indicate allocator errors. |
| Fam_Pmi_Exception | Indicate runtime initialization errors. |
| Fam_Unimplemented_Exception | Calling unimplemented OpenFAM APIs |
| Fam Error | Description |
|---|---|
| FAM_ERR_UNKNOWN | Unexpected or Unknown errors. |
| FAM_ERR_NOPERM | Caller does not have access rights for the desired operation. |
| FAM_ERR_TIMEOUT | Blocking APIs reached retry/timeout limit. |
| FAM_ERR_INVALID | APIs called with invalid options/arguments. |
| FAM_ERR_LIBFABRIC | Libfabric API failure. |
| FAM_ERR_SHM | Shared memory allocator error. |
| FAM_ERR_NOTFOUND | Data item or region not found in FAM. |
| FAM_ERR_ALREADYEXIST | Data item or region already exists in FAM. |
| FAM_ERR_ALLOCATOR | Allocator specific error |
| FAM_ERR_GRPC | Error from grpc layer. |
| FAM_ERR_PMI | Runtime error. |
| FAM_ERR_OUTOFRANGE | Data access out of range. |
| FAM_ERR_UNIMPL | Calling unimplemented functions/APIs. |
| FAM_ERR_RESOURCE | Resource not available. |
| FAM_ERR_INVALIDOP | Invalid operations |
Note that the library contains both blocking and non-blocking
calls for most data path operations. In case of errors, all blocking
calls throw exceptions immediately. For example, a call to
fam_put_blocking()
will either complete successfully, or throw one of
the following exceptions - Fam_InvalidOption_Exception
,
Fam_Allocator_Exception
, Fam_Datapath_Exception
or
Fam_Timeout_Exception
. In general, the application should use the
normal try-catch block to handle exceptions:
try { fam_put_blocking(); } catch (Fam_Exception &e) { // Exception handling code }
However, the non-blocking calls are queued within the library, and may not catch exceptions immediately. Depending on the underlying error, certain exceptions will be thrown immediately, while others may only be thrown during the next fam_quiet() call. Thus the code may look like:
try { fam_put_nonblocking(); } catch (Fam_Exception &e) { // handle (for example) // Fam_InvalidOption_Exception, Fam_Allocator_Exception, Fam_Datapath_Exception } // ... Continue rest of the code ... try { fam_quiet(); } catch (Fam_Exception &e) { // These exceptions may actually result // from a previous fam_put_nonblocking() operation // Fam_Timeout_Exception, Fam_Datapath_Exception }
Note that uncaught exceptions will result in the application being terminated.


A simple way to get the status of or query a Minecraft server.
We've currently gotten requests!
Having issues? Tweet me if anything is broken.
All requests should be sent to /server/status
or /server/query
.
You may add two parameters, an ip
and a port
.
JSONP is not supported as CORS is enabled.
Please do not send more than one request per client per minute as data is cached server side for five minutes.
An example request would look like https://mcapi.us/server/status?ip=s.nerd.nu
. If you are
using a non-standard 25565 port, you may include the port too, like this: https://mcapi.us/server/status?ip=s.nerd.nu&port=25565
.
Alternatively, you can use our JavaScript library. Here's a small example of it in use.

My awesome server is currently !

A response from this might look the following (live response data):
| name | description | example |
|---|---|---|
| status | the status of the request, typically success unless a poor request is made or my server is having internal troubles. if this is not success, assume the data is bad and should not be used. | success |
| online | if the server is online or not | true |
| motd | the server description, also known as the message of the day. some strange formatting may be in this, there are various libraries available for formatting this. | My Minecraft server |
| error | error message from the request. if you forget the IP the error will be missing data .
if it is an invalid IP, the error will be invalid hostname or port . if an error
starts with internal server error , it means something is wrong with my server.
empty means no error.
| |
| players.max | number of players that the server will allow | 20 |
| players.now | number of players currently online | 2 |
| server.name | current server version name | Spigot 1.8.3 |

If you're looking for more information about the server, such as what plugins are installed or the name
of the players currently online, you can try the /server/query
endpoint instead. It takes
the same parameters, and can be used with the provided JavaScript library by calling
MinecraftAPI.getServerQuery
instead.
However, query must be enabled on the server for this to work.
Images can be used on a forum, etc. to show your server's status when you can't use JavaScript.
Just add an image with the source https://mcapi.us/server/image?ip=server_ip
to your post or site.
If your server has an icon, it will use that. If not, it will show a standard grass block.
Add &port=25566
if you're using a non-standard port.
If you have a dark background, you can add &theme=dark
to the URL and it will make the text white instead.
If you prefer to show a different title or IP, you can change the first line of text with &title=YourMessage
.
Below is an example of the light and dark themes.
If something doesn't work or you're interested in a new feature, mention me on Twitter or send me an email.
