public interface Strategy
The Strategy
interface represents a strategy that can be
used to resolve and load the Class
objects that compose
a serializable object. A strategy implementation will make use of the
provided attribute node map to extract details that can be used to
determine what type of object must be used.
<xml version="1.0"> <example class="some.example.Demo"> <integer>2</integer> </example>The above example shows how the default strategy augments elements with "class" attributes that describe the type that should be used to instantiate a field when an object is deserialized. So looking at the above example the root element would be a "some.example.Demo".
Custom Strategy
implementations give the persister a
chance to intercept the class loading and type resolution for XML
documents. It also opens up the possibility for class versioning.
To establish contextual information a Map
object can be
used. The map object is a transient object that is created and used
for the duration of a single operation of the persister.

More details about the action:


The base module for Haml filters. User-defined filters should be modules including this module. The name of the filter is taken by downcasing the module name. For instance, if the module is named `FooBar`, the filter will be `:foobar`.
A user-defined filter should override either {#render} or {#compile}. {#render} is the most common. It takes a string, the filter source, and returns another string, the result of the filter. For example, the following will define a filter named `:sass`:
module Haml::Filters::Sass include Haml::Filters::Base def render(text) ::Sass::Engine.new(text).render end end
For details on overriding {#compile}, see its documentation.
Note that filters overriding {#render} automatically support `#{}` for interpolating Ruby code. Those overriding {#compile} will need to add such support manually if it’s desired.
This method is automatically called when {Base} is included in a module. It automatically defines a filter with the downcased name of that module. For example, if the module is named `FooBar`, the filter will be `:foobar`.
@param base [Module, Class] The module that this is included in
# File lib/haml/filters.rb, line 44 44: def self.included(base) 45: Filters.defined[base.name.split("::").last.downcase] = base 46: base.extend(base) 47: end
This should be overridden when a filter needs to have access to the Haml evaluation context. Rather than applying a filter to a string at compile-time, {#compile} uses the {Haml::Precompiler} instance to compile the string to Ruby code that will be executed in the context of the active Haml template.
Warning: the {Haml::Precompiler} interface is neither well-documented nor guaranteed to be stable. If you want to make use of it, you’ll probably need to look at the source code and should test your filter when upgrading to new Haml versions.
@param precompiler [Haml::Precompiler] The precompiler instance @param text [String] The text of the filter @raise [Haml::Error] if none of {#compile}, {#render}, and {#render_with_options} are overridden
# File lib/haml/filters.rb, line 96 96: def compile(precompiler, text) 97: resolve_lazy_requires 98: filter = self 99: precompiler.instance_eval do 100: if contains_interpolation?(text) 101: return if options[:suppress_eval] 102: 103: text = unescape_interpolation(text).gsub(/(\\+)n/) do |s| 104: escapes = $1.size 105: next s if escapes % 2 == 0 106: ("\\" * (escapes - 1)) + "\n" 107: end 108: newline if text.gsub!(/\n"\Z/, "\\n\"") 109: push_script find_and_preserve(#{filter.inspect}.render_with_options(#{text}, _hamlout.options)).strip, :escape_html => false 110: return 111: end 112: 113: rendered = Haml::Helpers::find_and_preserve(filter.render_with_options(text, precompiler.options), precompiler.options[:preserve]) 114: 115: if !options[:ugly] 116: push_text(rendered.rstrip.gsub("\n", "\n#{' ' * @output_tabs}")) 117: else 118: push_text(rendered.rstrip) 119: end 120: 121: (text.count("\n") - 1).times {newline} 122: resolve_newlines 123: newline 124: end 125: end
Same as {#compile}, but requires the necessary files first. *This is used by {Haml::Engine} and is not intended to be overridden or used elsewhere.*
@see #
# File lib/haml/filters.rb, line 78 78: def internal_compile(*args) 79: resolve_lazy_requires 80: compile(*args) 81: end
This becomes a class method of modules that include {Base}. It allows the module to specify one or more Ruby files that Haml should try to require when compiling the filter.
The first file specified is tried first, then the second, etc. If none are found, the compilation throws an exception.
For example:
module Haml::Filters::Markdown lazy_require 'rdiscount', 'peg_markdown', 'maruku', 'bluecloth' ... end
@param reqs [Array
# File lib/haml/filters.rb, line 145 145: def lazy_require(*reqs) 146: @lazy_requires = reqs 147: end
Takes the source text that should be passed to the filter and returns the result of running the filter on that string.
This should be overridden in most individual filter modules to render text with the given filter. If {#compile} is overridden, however, {#render} doesn’t need to be.
@param text [String] The source text for the filter to process @return [String] The filtered result @raise [Haml::Error] if it’s not overridden
# File lib/haml/filters.rb, line 59 59: def render(text) 60: raise Error.new("#{self.inspect}#render not defined!") 61: end
Same as {#render}, but takes a {Haml::Engine} options hash as well. It’s only safe to rely on options made available in {Haml::Engine#options_for_buffer}.
@see # @param text [String] The source text for the filter to process @return [String] The filtered result @raise [Haml::Error] if it or {#render} isn’t overridden
# File lib/haml/filters.rb, line 70 70: def render_with_options(text, options) 71: render(text) 72: end
# File lib/haml/filters.rb, line 151 151: def resolve_lazy_requires 152: return unless @lazy_requires 153: 154: @lazy_requires[0...1].each do |req| 155: begin 156: @required = req 157: require @required 158: return 159: rescue LoadError; end # RCov doesn't see this, but it is run 160: end 161: 162: begin 163: @required = @lazy_requires[1] 164: require @required 165: rescue LoadError => e 166: classname = self.name.match(/\w+$/)[0] 167: 168: if @lazy_requires.size == 1 169: raise Error.new("Can't run #{classname} filter; required file<EMAIL_ADDRESS>not found") 170: else 171: raise Error.new("Can't run #{classname} filter; required<EMAIL_ADDRESS>{ |r| "'#{r}'" }.join(' or ')}, but none were found") 172: end 173: end 174: end

Collaborations
Who We Helped
University of Ottawa
uOttawa reached out to us for modeling help for their tristable switch. Go to their wiki page for details.
Aalto-Helsinki
We provided bulk data from the 2014 teams for Aalto-Helsinki's Team Seeker software tool to better search abstracts from all 2014 iGEM teams. We also provided information for the team's Collab Seeker tool.
Tec-Monterrey
We provided three plasmids to the Tec-Monterrey team from our 2014 project. The first plasmid contained DsRed, ermM, Amp, oriV (S. aureus) + oriV (E. coli), the second had oriT-Nes, and the third had the trs region.
Surveys completed and shared
We were asked to fill out and share a number of surveys, and did so for the following teams: University of Indonesia, IIT Kharagpur, Paris-Saclay and University College London.
Who Helped Us
University of Ottawa
We had some trouble with assembling some of our plant constructs, and the uOttawa team stepped in and helped us out. They assembled most of our [insert link to plasmids] for us using yeast. From here we used Gibson Assembly to add our B2 target to complete the plasmid.
University of Toronto
Toronto provided some business expertise and related to our scale-up project, including some insights into what markets to look at and intellectual property rights.
Queen's University
The Queen's team helped us with understanding PyRosetta and its inner workings a little better, which helped us develop our PyRosetta tools.
oGEM
The five Ontario, Canada iGEM teams (McMaster, Toronto, Queen's, Ottawa, and Waterloo) have worked with each other over the course of the year to help build each other's projects. We provided general wet and dry lab support for each other, as well specifics for protocols, business advice, and contacts.
We had two meetups over the spring and summer, one to help with project ideas and identifying interesting topics to pursue, and the other to provide feedback on presentations, general advice for preparing for the Jamboree, and sharing wiki content to make set up and development easier.
Sharing and collaboration are core values of iGEM. We encourage you to reach out and work with other teams on difficult problems that you can more easily solve together.
Which other teams can we work with?
You can work with any other team in the competition, including software, hardware, high school and other tracks. You can also work with non-iGEM research groups, but they do not count towards the iGEM team collaboration gold medal criterion.
In order to meet the gold medal criteria on helping another team, you must complete this page and detail the nature of your collaboration with another iGEM team.
Here are some suggestions for projects you could work on with other teams:
- Improve the function of another team's BioBrick Part or Device
- Characterize another team's part
- Debug a construct
- Model or simulating another team's system
- Test another team's software
- Help build and test another team's hardware project
- Mentor a high-school team

| |
Set the kernel device class of a RTDM driver.
Set the kernel device class assigned to the RTDM driver. By default, RTDM drivers belong to Linux's "rtdm" device class, creating a device node hierarchy rooted at /dev/rtdm, and sysfs nodes under /sys/class/rtdm.
This call assigns a user-defined kernel device class to the RTDM driver, so that its devices are created into a different system hierarchy.
rtdm_drv_set_sysclass() is meaningful only before the first device which is attached to drv is registered by a call to rtdm_dev_register().
- Parameters
-
| [in] | drv | Address of the RTDM driver descriptor. |
| [in] | cls | Pointer to the kernel device class. NULL is allowed to clear a previous setting, switching back to the default "rtdm" device class. |
- Returns
- 0 on success, otherwise:
- -EBUSY is returned if the kernel device class has already been set for drv, or some device(s) attached to drv are currently registered.
- Tags
- task-unrestricted
- Attention
- The kernel device class set by this call is not related to the RTDM class identification as defined by the RTDM profiles in any way. This is strictly related to the Linux kernel device hierarchy.

Allocate mapping region in address space.
When present, this optional handler should return the start address of a free region in the process's address space, large enough to cover the ongoing mmap() operation. If unspecified, the default architecture-defined handler is invoked.
Most drivers can omit this handler, except on MMU-less platforms (see second note).
- Parameters
-
| [in] | fd | File descriptor |
| [in] | len | Length of the requested region |
| [in] | pgoff | Page frame number to map to (see second note). |
| [in] | flags | Requested mapping flags |
- Returns
- The start address of the mapping region on success. On failure, a negative error code should be returned, with -ENOSYS meaning that the driver does not want to provide such information, in which case the ongoing mmap() operation will fail.
- Note
- The address hint passed to the mmap() request is deliberately ignored by RTDM, and therefore not passed to this handler.
-
On MMU-less platforms, this handler is required because RTDM issues mapping requests over a shareable character device internally. In such context, the RTDM core may pass a null pgoff argument to the handler, for probing for the logical start address of the memory region to map to. Otherwise, when pgoff is non-zero, pgoff << PAGE_SHIFT is usually returned.

Mainly dmg is the great power of low magic servers so Bane of enemies is of course needed and lots og favored enemies, because the dangers will be many and fierce.
So lots of FE's, either sneak dmg(dexer) or FTR dmg(STR). Dont like casting so any dmg from spells....no chance
Also it's preferable with either Elf, human or dwarf as a race.
Any ideas would be wonderful and remember it is low magic so it's essential that i have both HP and DMG. That is why im leaning towards a sort of sneaker because i wouldn't rely too much on HPs then.
But anyhow...! Need help on this one

Maybe the advice given there may answer at least some of your questions.
Rogue 13/Ranger 21/Fighter 6. Bane of Enemies, 7d6 sneaks, and Epic Weapon Spec mean you should be able to do some serious damage. Feel free to go either Dex or Str-based, whichever you prefer. If you go Str-based, you will probably want Improved Evasion, and you course Crippling Strike is always fun as it will weaken your opponent every time you make a successful sneak attack.


CSNK1
A casein kinase that was originally described as a monomeric enzyme with a molecular weight of 30-40 kDa. Several ISOENZYMES of casein kinase I have been found which are encoded by separate genes. Many of the casein kinase I isoenzymes have been shown to play distinctive roles in intracellular SIGNAL TRANSDUCTION.

C Language is a structure-oriented, middle-level programming language mostly used to develop low-level applications.
C Language is used to develop systems applications that are integrated into operating systems such as Windows, UNIX and Linux, as well as embedded softwares. Applications include graphics packages, word processors, spreadsheets, operating system development, database systems, compilers and assemblers, network drivers and interpreters.
• Facebook’s TAO systems is programmed mostly using C language.
• Most device drivers are still developed using C Language.
o Simple to learn; there are only 32 keywords to master
o Easy to write systems programs such as compilers and interpreters
o Foundational language for beginners
HTML was created by physicist Tim Berners-Lee in 1990 to allow scientists to share documents online. Before then, all communication was sent using plain text. HTML made “rich” text possible (i.e. text formatting and visual images).


On the other hand, the US is demanding greater market access through a cut in import duties for its agriculture dairy products, medical devices, IT and communication items. India has stated that it would be difficult for them to cut duties on IT products.India imposed retaliatory tariffs on the US after withdrawal of key trade privileges, which will lead to an increase in prices of almonds, walnuts and apples among other products.

This is the first project I made in my class on 2D Game Engines. The first assignment was to simply make Tic-Tac-Toe, the game we all know and love.
The Project is made entirely out of java with event handling and the creation of the game window achieved using Swing. Everything seen inside the window was painted using Java's Graphics2D object. Part of the fun of this project was that I had to create my own UI Kit for displaying and positioning elements.
The system uses bounding boxes for each element on screen. The positioning of elements is calculated as an offset x and y from the parent object's origin where x is some percentage of the parent's width and y is some percentage of the parent's height. An element's own x and y values are also percentages of its parent's x and y values. This made positioning elements quite easy. If you wanted an element to be positioned exactly in the center of its parent, just set its offset to be 25% x and y, and its size to be 50% x and y. This would push the origin of the element 25% percent into its parent, followed by the element taking 50% of its parent's width, and then the last 25% to the element's right and bottom.
The game implements all the basic rules of Tic-Tac-Toe
Player two wins!
It's a draw!
All the elements also support resizing. What took a little more work than I thought was getting the resizing of text to work just right. When a text box resizes it searches for the the font sizes that fits in both height and width by doing a binary search on the available font sizes. It finds the upper bound first by doubling the current font size until it doesn't fit.
Here we have the game in full screen mode.


Version Control and friends
The subtitle, if you want it. I do not.
Today's Date
What is Version control and why is it important? Version control is a save point. It allows a creator to continue working on a project while continually saving rough drafts or different iterations of the creators work. If a mistake is made, the creator can go back and pull up an earlier version. If the creator changes his or her mind, or wants to attempt muliple possibilities, version control will allow the creator to do so and to return to any other point.
Git is the program that helps you keep track of those changes. It does so by keeping track of the differences so the user does not have to store all the memory of each of the different interations of the users projects. Git is local. Github is remote.
GitHub is where users can store their projects remotely. This is useful because it allows creators to share and collaborate, all the while keeping track of all the different interations. It also allows users to access it from anywhere with an available network. #DBCgit


IU dedicates 'Love Poem' to a 'friend she can no longer see'
by jennywillIU dedicated a song for Sulli at her '2019 IU Concert Love Poem'.
IU and Sulli are well-known friends. At the end of her 4-hour concert, IU's first encore song was "Good Day". After the song, IU said, "There is a friend who I recently became unable to see. I was worried that I would break apart on stage. I prepared this stage thinking that I didn't want to cry. It's been a month since I was able to see her. I didn't want her to see that I was suffering because of her, so I did my best to be strong. I feel better because I think I was able to show her a good stage. Even if she can't come to my non-Seoul concerts, she always came to my Seoul concerts and stayed until the encore stage was over. Usually, she doesn't stay for the second encore song, so I want her to hear this song."
She then sang "Love Poem", the titular song from her 5th mini-album. She added, "Whenever I wrote a song and asked her for feedback, she always asked why things were a certain way. I wrote this song to give strength to people who were having a hard time. I always sing with all my heart, but this time, I'll put even more into it."

Proudly presenting the Dynamic App framework
An HTML template with value binding and automatic instancing
The MVC design pattern is a great one and already implemented in various frameworks. Some, like
JSP,
Thymeleaf rely mainly on server-side generated content and a fast-growing number (
Angular,
Handlebars,
Knockout,
Vue, and many more ) emphasize on client-side routing and rendering. Other platforms (e.g. Ruby on Rails) are a mixture, where the developers are invited to use the approach they understand
best.
New HTML developments are not compatible with older browsers ( <template> tag, Polymer ).
Serve data and web pages
The framework presented here, assumes that the Models, including business rules reside on a data server and the Controllers (with possibly workflow) on a Web server. Of course these two servers can be one instance, but also on different, load-balanced ones.
The Controllers should output clean, valid HTML5 with the accompanying CSS. These pages themselves only provide data interaction, client-side, to the user. The data to be shown and/or manipulated is retrieved asynchronously from the data server.
Presenting an IE9+ and other browsers compatible framework. Fully written in ECMA script v5 (the Javascript of those browers). It aims to deliver both HTML templates to ensure a standardised way of rendering commonly used element constructs as well as value binding to automate most of the template instantiation and linking all elements and nodes that logically represent the same data items.
The shown Javascript in the right panel uses the proposed framework. This dedicated code is only necessary since the proposed data server is not available on the Codepen.io website (and also not yet implemented)
Try to set other log levels in the Javascript and see what happens on the console, and even in the element inspector.


Problem 1. JavaScript literals
- Assign all the possible JavaScript literals to different variables.
Problem 2. Quoted text
- Create a string variable with quoted text in it.
- For example: `'How you doin'?', Joey said'.
Problem 3. Typeof variables
- Try typeof on all variables you created.
Problem 4. Typeof null
- Create null, undefined variables and try typeof on them.

Torque 2D - Mounting Tutorial
In this document, you will learn how to mount objects to each other via the Scene Editor. This tutorial covers all the basics of mounting and is intended for complete beginners to T2D. Have fun!
Before we continue, we are going to need some additional images and particles. If you have not already done so in a past tutorial, click here for instructions on adding the additional assets.click here for instructions on adding the additional assets.
|
Figure 1 |
Now you should see an empty screen with the default T2D loaded content as shown below:
The scene view background colors might change in the tutorials' figures to provide optimal contrast. You can configure the color to your liking as well under Edit > Preferences... in the Scene Editor tab. With that out of the way, let's create a simple example!
From the static sprites rollout, drag the cloudsImageMap into the scene view and inside the thick dark blue-lined rectangle overlayed on the grid. This rectangle is called the camera view as shown below.
Increase the size of the image slightly. After that, scroll down in the Create Tab to the particle effects rollout. Find the rain.eff effect and drag that into the scene view as well. Increase the horizontal size of the rain so it matches the length of the large cloud. In the quick access button list that appears above a selected object when the mouse is over it, find the mount button as shown below.
After you click the button, the particle effect's midpoint is now attached to the cursor. Left click on the lower portion of the cloud to complete the mounting operation as shown below.
If you wish to check if the particle effect is truly mounted, select the cloud. In the quick edit tab, press the "Edit this objects link points" button. You should now see a small block with the number 0 where you originally clicked to mount the particle effect.
Click save in the Linkpoint Editor to continue.
Now drag the cloud over to the top right corner of the camera view. As you can see, the rain followed as well. Click on the Edit Tab and find the Physics rollout. When you've found it, change the Velocity in X to -10.
Save your scene with whatever name you wish. If you do not know how to save your scene, click here.If you do not know how to save your scene, click here.
Now press
the play button in the toolbar (click here if you do not know where the play button is)(click here if you do not know where the play button is). The cloud and rain, which is mounted
to the cloud, are moving across the screen! With object mounting it
is easy to have multiple, now connected objects share similar
properties, like velocity values as shown below.
Good job, we have the
basics now covered. Ready to learn some more advanced mounting
techniques? Start off by creating a new scene.
Now you have a fresh, new
scene to work in (all within the same project of course). Scroll
down to the rollout called Other in the Create Tab. The first object
of the three shown is called a
SceneObject. A t2dSceneObject is the base class from which all
objects, like static sprites, are derived. Drag the SceneObject into
the middle of the screen, preferably at location (0,0).
After you have done that,
you should see a bordered square.
The following will be a
slightly different way to mount objects. In the
quick access button list, select the edit link points button.
Click in the center of
the square to add a link point. You add a link point by simply
clicking anywhere on this object, the link point will be added
automatically. This will be given the number 0 as seen above.
Click on the selection tool or hit Enter to return to the Scene Editor. Now, drag the particlebeam.eff, found in the Particle
Effects rollout, and place it next to your SceneObject.
In the particle beam's
quick access button list, click on the mount button. When the particle is mounted to your cursor for
placement, notice the yellow crosshairs where we placed our link
point in the SceneObject.
When you bring the cursor
close to the crosshairs, it will snap to those coordinates. Click
again with your mouse to complete the mounting operation.
Let's learn a bit more
about how to modify mounted objects using the Scene Editor. Click on
the SceneObject. If it is hard to select from the scene view, you can
always select the object from the Project Tab, under the Object Tree.
Once you have the SceneObject selected, click on the Edit Tab and
open up the Mounting rollout. Inside there will be two editable
fields.
The first field,
Rotation, will rotate the mounted object or mount system. An
important point: the SceneObject will not be rotated, only the
particle effect that is mounted to it.
The next field, Auto
Rotation, sets the degrees per second rotation of the particle effect. Try it out, you can see it rotate
within the scene view. Leave it rotating for the next part.
Now that we have seen
what we can edit from the SceneObject, let's look at the options in
the Mounting rollout for the particle itself. Select the particle
effect and go to the Edit Tab again. Under this particular Mounting
rollout, we have a few more options.
Rotation and Auto
Rotation will not do anything if modified because these fields
only apply to the object that we mounted to, not the object
that is mounted.
Mount Force is the
force constantly applied to the object allowing it to 'chase' the
specified mount point. A force of 0 indicates that the mount is rigid
and will track the mount-point perfectly every frame.
The Track Rotation
checkbox specifies that this object should always track the target's
rotation when checked. If you uncheck this box, you can see that the
particle effect stops rotating. Check it again and it will continue
to rotate.
Owned By Mount,
when checked, indicates whether the object is to be owned by the
object it's mounting to. What this means is that when the
object that we’re mounting to is deleted, this object is
automatically deleted. This is extremely useful for objects that are
mounted that you don’t want to explicitly track.
If you check Inherit
Attributes, this indicates whether the object inherits attributes
from the object being mounted to. At the moment, the
following attributes are inherited: Enabled, Visible, Paused and
Flip.
Hopefully you have a
better understanding now of mounts and the T2D mounting system. As a
final note for this tutorial, in our last example we rotated an
object at the center of the square SceneObject box. This is also
known as it's pivot point. Any mounted object, regardless of where
the mount point is, will rotate around this pivot point. This means,
if you mounted the particle effect towards the edge of the square and
set it to rotate, it does not rotate around the mount point where
you clicked, but instead around the pivot point in the center of the
square. This is an intended feature of
T2D and not a bug.

As a new user, Will wants to purchase last-minute tickets to a
Broncos
game.


You will need to do this assignment on the department server
(cs.monm.edu
). Start early so you can comfortable in that
environment.
Starting from this template, complete the power
function. It takes in a base (a double
), an exponent called exp
(an int
), and should return base
raised to the exp
power. In
other words, baseexp.
The main
function allows the user to enter inputs and perform the
exponentiation operation. If you would like to write tests for your
code (recommended), place it near the TESTING HERE
block at the
start of main()
. Do not modify below that point.
For testing, you might try running man assert
on the command line,
or try searching for “assert.h” online.
Start from this template. First, complete the foobar
function. Given an input integer n
, foobar
should loop from 1 to n
(inclusive). For each number, foobar
will print a value on a
separate line. If the number is divisible by 4, it should print
“Foo”. If the number is divislbe by 6, it should print “Bar”. If the
number is divisible by 4 AND 6, it should print “FooBar”. Otherwise,
it should print the number itself.
For example, calling foobar(7)
should print
1
2
3
Foo
5
Bar
7
Your main
function should first check the number of arguments. The
program itself should take exactly one argument, e.g., ./a.out
7
. With any other number of arguments, the program should print an
error message and immediately stop, returning 1.
When given a single argument, you should convert the argument into an
integer, call foobar
with it, and return 0. You do not need to do
any error checking on the argument itself – you may assume it is an
integer.
We will submit using the handin
program. Assuming you have not
renamed the files, you can run
handin comp235 proj1 expt.c foobar.c
to submit your solutions. You can run this command multiple times in case you discover an error after submitting.


Pre-Olympic qualifiers: D’Tigress ease past DR Congo
by The Eagle OnlineD’Tigress started their FIBA Africa Pre-Olympics Qualifiers started on a winning note after strolling over DR Congo, 20-0 points.
The Otis Hughley side performed a walk over ceremony over DR Congo who failed to show up for the competition holding in Maputo, Mozambique.
Currently ranked first in Africa and 16th in the world, the team shot to the top of group A with one match to go.
The reigning African Champions will now shift their attention to their last group game against Mozambique on Saturday after booking an automatic semi final ticket.
Winners of the semi final encounters will qualify for the Olympics Qualifying Tournament to be held next year.
It would be recalled that Hughley settled for Ezinne Kalu, Promise Amukamara, Elo Edema, Atonye Nyingifa, Sarah Imovbioh and Pallas Kunaiyi-Akpannah.
Others include Upe Atosu, Aisha Balarabe, Evelyn Akhator, Ifunnanya Ibekwe, Adaora Elonu and Victoria Macaulay.

Isotope collections can be sorted according to set criteria. Sorting is controlled by clickable elements in a sorter group. An Isotope collection may have many sorter groups linked to it.
To create a sorter group, create an element with attribute data-isotope-sorters
. This can be placed anywhere on the page, and does not need to be placed adjacent to the Isotope layout.
When using sorters, the data-isotope-collection
and data-isotope-sorters
elements must have a matching data-isotope-id
attribute. This is what links the two elements, allowing multiple Isotope collections
per page, and multiple sorter groups per collection.
Any element inside the data-isotope-sorters
element with attribute data-sort
and data-sort-selector
is considered a clickable sorter.
Class active
is applied to sorters when clicked, while being removed from all other sorters in the collection.

Built-In Sort Methods
Isotope has two built-in sorting methods. To use these sorting methods, add the following required attributes to your button or link.
| Required Attributes |
Description |
data-sort="original-order" data-sort-selector="original-order"
|
This sorts the Isotope items into the original order laid out in HTML. |
data-sort="random" data-sort-selector="random"
|
Randomizes the order of the items with each click. |
Custom Sort Methods
Isotope items can be sorted according to text or data held within the markup of each item. Custom sort methods are defined by the clickable elements in the data-isotope-sorters

.
Each sort method requires the following two attributes:
- A unique
id
for the sort method, defined by the data-sort
attribute. Eg. "sortByName"
, or "sortByRanking"
.
- A source for the data defined by the
data-sort-selector
attribute. This selector points to an element or attribute which each Isotope item has in common.
Sorting data can be taken from the following sources
| Source |
data-sort-selector
|
| Text of child element of Isotope items |
A selector which identifies the item. Eg. "span" or ".likes-count"
|
| Text of child element of Isotope items parsed as integer
|
A selector which identifies the item with the addition of parseInt directive. Eg. "span parseInt" or ".likes-count parseInt"
|
| Text of child element of Isotope items parsed as float
|
A selector which identifies the item with the addition of parseFloat directive. Eg. "span parseFloat" or ".longitude parseFloat"
|
| Plain attribute on an Isotope item |
"[src]" , "[href]" , "[alt]" etc. |
| Data attribute on Isotope item |
"[data-category]" , "[data-likes]" , "[data-index]" , "[data-ranking]" etc. |
Note: If you are familiar with the Isotope plugin, the data-sort
value is used internally as each key in Isotope's getSortData
configuration option. See documentation for more detail.
Examples
In the following examples, the items will be sorted in ascending order, which is the default. See Sort Ascending / Descending below.
data-sort-selector=".name" // Sort by text of child element with class 'name'.
data-sort-selector=".symbol" // Sort by text of child element with class 'symbol'.
data-sort-selector="[data-category]" // Sort by alphabetic text of the `data-category` attribute.
data-sort-selector=".number parseInt" // Sort by text of child element with class 'number', parsed as an integer.
data-sort-selector=".weight parseFloat" // Sort by text of element with class 'weight', parsed as a float.
For more examples, please see the Isotope Documentation.


Math¶
At the root of computer vision is a heavy amount of math and probability. Theia contains various math functions implemented with a generic interface for ease of use.
Closed Form Polynomial Solver¶
Many problems in vision rely on solving a polynomial quickly. For small degrees (n <= 4) this can be done in closed form, making them exceptionally fast. We have implemented solvers for these cases.
- int SolveQuadraticReals(double a, double b, double c, double* roots)¶
- int SolveQuadratic(double a, double b, double c, std::complex<double>* roots)¶
Provides solutions to the equation \(a*x^2 + b*x + c = 0\)
- int SolveCubicReals(double a, double b, double c, double d, double* roots)¶
- int SolveCubic(double a, double b, double c, double d, std::complex<double>* roots)¶
Provides solutions to the equation \(a*x^3 + b*x^2 + c*x + d = 0\) using Cardano’s method.
- int SolveQuarticReals(double a, double b, double c, double d, double e, double* roots)¶
- int SolveQuartic(double a, double b, double c, double d, double e, std::complex<double>* roots)¶
Provides solutions to the equation \(a*x^4 + b*x^3 + c*x^2 + d*x + e = 0\) using Ferrari’s method to reduce to problem to a depressed cubic.
Generic Polynomial Solver¶
For polynomials of degree > 4 there are no easy closed-form solutions, making the problem of finding roots much more difficult. However, we have implemented several functions that will solve for polynomial roots. For all polynomials we require that the largest degree appears first and the smallest degree appears last in the input VectorXd.
- bool FindPolynomialRoots(const Eigen::VectorXd& polynomial, Eigen::VectorXd* real, Eigen::VectorXd* imaginary)¶
Roots are computed using the Companion Matrix with balancing to help improve the condition of the matrix system we solve. This is a reliable, stable method for computing roots but is most often the slowest method.
- bool FindRealPolynomialRoots(const Eigen::VectorXd& polynomial, Eigen::VectorXd* real)¶
Using the Companion Matrix method above, we return only the real roots of the polynomial.
- bool FindRealPolynomialRootsSturm(const Eigen::VectorXd& coeffs, Eigen::VectorXd* real_roots)¶
Real roots are bracketed within a boundary by analyzing Sturm sequences. Once a root has been isolated to a bound, an iterative solver is used to determine the actual root.
- double FindRealRootIterative(const Eigen::VectorXd& polynomial, const double x0, const double epsilon, const int max_iter)¶
Finds a single polynomials root iteratively based on the starting position \(x_0\) and guaranteed precision of epsilon.
Guass-Jordan¶
- void GaussJordan(Eigen::MatrixBase<Derived>* input, int max_rows=99999)¶
Perform traditional Gauss-Jordan elimination on an Eigen3 matrix. If max_rows is specified, it will on perform Gauss-Jordan on the first max_rows number of rows. This is useful for problems where your system is extremely overdetermined and you do not need all rows to be solved.
Sequential Probability Ratio Test¶
Modified version of Wald’s SPRT as [Matas] et. al. implement it in “Randomized RANSAC with Sequential Probability Ratio Test”
- double CalculateSPRTDecisionThreshold(double sigma, double epsilon, double time_compute_model_ratio=200.0, int num_models_verified=1)¶
sigma: Probability of rejecting a good model (Bernoulli parameter).
epsilon: Inlier ratio.
time_compute_model_ratio: Computing the model parameters from a sample takes the same time as verification of time_compute_model_ratio data points. Matas et. al. use 200.
num_model_verified: Number of models that are verified per sample.
Returns: The SPRT decision threshold based on the input parameters.
- bool SequentialProbabilityRatioTest(const std::vector<double>& residuals, double error_thresh, double sigma, double epsilon, double decision_threshold, int* num_tested_points, double* observed_inlier_ratio)¶
Modified version of Wald’s SPRT as [Matas] et. al. implement it in “Randomized RANSAC with Sequential Probability Ratio Test”. See the paper for more details.
residuals: Error residuals to use for SPRT analysis.
error_thresh: Error threshold for determining when Datum fits the model.
sigma: Probability of rejecting a good model.
epsilon: Inlier ratio.
decision_threshold: The decision threshold at which to terminate.
observed_inlier_ratio: Output parameter of inlier ratio tested.


Installing Guacamole with Docker¶
Guacamole can be deployed using Docker, removing the need to build guacamole-server from source or configure the web application manually. The Guacamole project provides officially-supported Docker images for both Guacamole and guacd which are kept up-to-date with each release.
A typical Docker deployment of Guacamole will involve three separate containers, linked together at creation time:
guacamole/guacd
Provides the guacd daemon, built from the released guacamole-server source with support for VNC, RDP, SSH, telnet, and Kubernetes.
guacamole/guacamole
Provides the Guacamole web application running within Tomcat 8 with support for WebSocket. The configuration necessary to connect to guacd, MySQL, PostgreSQL, LDAP, etc. will be generated automatically when the image starts based on Docker links or environment variables.
mysql
orpostgresql
Provides the database that Guacamole will use for authentication and storage of connection configuration data.
This separation is important, as it facilitates upgrades and maintains proper separation of concerns. With the database separate from Guacamole and guacd, those containers can be freely destroyed and recreated at will. The only container which must persist data through upgrades is the database.
Running the guacd Docker image¶
The guacd Docker image is built from the released guacamole-server source with support for VNC, RDP, SSH, telnet, and Kubernetes. Common pitfalls like installing the required dependencies, installing fonts for SSH, telnet, or Kubernetes, and ensuring the FreeRDP plugins are installed to the correct location are all taken care of. It will simply just work.
Running guacd for use by the Guacamole Docker image¶
When running the guacd image with the intent of linking to a Guacamole container, no ports need be exposed on the network. Access to these ports will be handled automatically by Docker during linking, and the Guacamole image will properly detect and configure the connection to guacd.
$ docker run --name some-guacd -d guacamole/guacd
When run in this manner, guacd will be listening on its default port 4822, but
this port will only be available to Docker containers that have been explicitly
linked to some-guacd
.
The log level of guacd can be controlled with the GUACD_LOG_LEVEL
environment
variable. The default value is info
, and can be set to any of the valid
settings for the guacd log flag (-L).
$ docker run -e GUACD_LOG_LEVEL=debug -d guacamole/guacd
Running guacd for use by services outside Docker¶
If you are not going to use the Guacamole image, you can still leverage the guacd image for ease of installation and maintenance. By exposing the guacd port, 4822, services external to Docker will be able to access guacd.
Important
Take great care when doing this - guacd is a passive proxy and does not perform any kind of authentication.
If you do not properly isolate guacd from untrusted parts of your network, malicious users may be able to use guacd as a jumping point to other systems.
$ docker run --name some-guacd -d -p 4822:4822 guacamole/guacd
guacd will now be listening on port 4822, and Docker will expose this port on the same server hosting Docker. Other services, such as an instance of Tomcat running outside of Docker, will be able to connect to guacd directly.
The Guacamole Docker image¶
The Guacamole Docker image is built on top of a standard Tomcat 8 image and takes care of all configuration automatically. The configuration information required for guacd and the various authentication mechanisms are specified with environment variables or Docker links given when the container is created.
Important
If using PostgreSQL or MySQL for authentication, you will need to initialize the database manually. Guacamole will not automatically create its own tables, but SQL scripts are provided to do this.
Once the Guacamole image is running, Guacamole will be accessible at
http://HOSTNAME:8080/guacamole/
, where HOSTNAME
is the hostname or
address of the machine hosting Docker.
Configuring Guacamole when using Docker¶
When running Guacamole using Docker, the traditional approach to configuring
Guacamole by editing guacamole.properties
is less convenient. When using
Docker, you may wish to make use of the enable-environment-properties
configuration property, which allows you to specify values for arbitrary
Guacamole configuration properties using environment variables. This is covered
in Configuring Guacamole.
Connecting Guacamole to guacd¶
The Guacamole Docker image needs to be able to connect to guacd to establish remote desktop connections, just like any other Guacamole deployment. The connection information needed by Guacamole will be provided either via a Docker link or through environment variables.
If you will be using Docker to provide guacd, and you wish to use a Docker link to connect the Guacamole image to guacd, the connection details are implied by the Docker link:
$ docker run --name some-guacamole \
--link some-guacd:guacd \
...
-d -p 8080:8080 guacamole/guacamole
If you are not using Docker to provide guacd, you will need to provide the network connection information yourself using additional environment variables:
GUACD_HOSTNAME
The hostname of the guacd instance to use to establish remote desktop connections. This is required if you are not using Docker to provide guacd.
GUACD_POST
The port that Guacamole should use when connecting to guacd. This environment variable is optional. If not provided, the standard guacd port of 4822 will be used.
The GUACD_HOSTNAME
and, if necessary, GUACD_PORT
environment variables can
thus be used in place of a Docker link if using a Docker link is impossible or
undesirable:
$ docker run --name some-guacamole \
-e GUACD_HOSTNAME=<IP_ADDRESS> \
-e GUACD_PORT=4822 \
...
-d -p 8080:8080 guacamole/guacamole
A connection to guacd is not the only thing required for Guacamole to work; some authentication mechanism needs to be configured, as well. MySQL, PostgreSQL, and LDAP are supported for this, and are described in more detail in the sections below. If the required configuration options for at least one authentication mechanism are not provided, the Guacamole image will not be able to start up, and you will see an error.
MySQL authentication¶
To use Guacamole with the MySQL authentication backend, you will need either a
Docker container running the mysql
image, or network access to a working
installation of MySQL. The connection to MySQL can be specified using either
environment variables or a Docker link.
Initializing the MySQL database¶
If your database is not already initialized with the Guacamole schema, you will need to do so prior to using Guacamole. A convenience script for generating the necessary SQL to do this is included in the Guacamole image.
To generate a SQL script which can be used to initialize a fresh MySQL database as documented in Database authentication:
$ docker run --rm guacamole/guacamole /opt/guacamole/bin/initdb.sh --mysql > initdb.sql
Alternatively, you can use the SQL scripts included with the database authentication.
Once this script is generated, you must:
Create a database for Guacamole within MySQL, such as
guacamole_db
.Create a user for Guacamole within MySQL with access to this database, such as
guacamole_user
.Run the script on the newly-created database.
The process for doing this via the mysql utility included with MySQL is documented Database authentication.
Connecting Guacamole to MySQL¶
If your MySQL database is provided by another Docker container, and you wish to use a Docker link to connect the Guacamole image to your database, the connection details are implied by the Docker link itself:
$ docker run --name some-guacamole \
--link some-guacd:guacd \
--link some-mysql:mysql \
...
-d -p 8080:8080 guacamole/guacamole
If you are not using Docker to provide your MySQL database, you will need to provide the network connection information yourself using additional environment variables:
MYSQL_HOSTNAME
The hostname of the database to use for Guacamole authentication. This is required if you are not using Docker to provide your MySQL database.
MYSQL_PORT
The port that Guacamole should use when connecting to MySQL. This environment variable is optional. If not provided, the standard MySQL port of 3306 will be used.
The MYSQL_HOSTNAME
and, if necessary, MYSQL_PORT
environment variables can
thus be used in place of a Docker link if using a Docker link is impossible or
undesirable:
$ docker run --name some-guacamole \
--link some-guacd:guacd \
-e MYSQL_HOSTNAME=<IP_ADDRESS> \
...
-d -p 8080:8080 guacamole/guacamole
Note that a Docker link to guacd (the --link some-guacd:guacd
option above)
is not required any more than a Docker link is required for MySQL. The
connection information for guacd can be specified using environment variables,
as described in Connecting Guacamole to guacd.
Required environment variables¶
Using MySQL for authentication requires additional configuration parameters specified via environment variables. These variables collectively describe how Guacamole will connect to MySQL:
MYSQL_DATABASE
The name of the database to use for Guacamole authentication.
MYSQL_USER
The user that Guacamole will use to connect to MySQL.
MYSQL_PASSWORD
The password that Guacamole will provide when connecting to MySQL as
MYSQL_USER
.
If any required environment variables are omitted, you will receive an error message in the logs, and the image will stop. You will then need to recreate the container with the proper variables specified.
Optional environment variables¶
Additional optional environment variables may be used to override Guacamole’s default behavior with respect to concurrent connection use by one or more users. Concurrent use of connections and connection groups can be limited to an overall maximum and/or a per-user maximum:
MYSQL_ABSOLUTE_MAX_CONNECTIONS
The absolute maximum number of concurrent connections to allow at any time, regardless of the Guacamole connection or user involved. If set to “0”, this will be unlimited. Because this limit applies across all Guacamole connections, it cannot be overridden if set.
By default, the absolute total number of concurrent connections is unlimited (“0”).
MYSQL_DEFAULT_MAX_CONNECTIONS
The maximum number of concurrent connections to allow to any one Guacamole connection. If set to “0”, this will be unlimited. This can be overridden on a per-connection basis when editing a connection.
By default, overall concurrent use of connections is unlimited (“0”).
MYSQL_DEFAULT_MAX_GROUP_CONNECTIONS
The maximum number of concurrent connections to allow to any one Guacamole connection group. If set to “0”, this will be unlimited. This can be overridden on a per-group basis when editing a connection group.
By default, overall concurrent use of connection groups is unlimited (“0”).
MYSQL_DEFAULT_MAX_CONNECTIONS_PER_USER
The maximum number of concurrent connections to allow a single user to maintain to any one Guacamole connection. If set to “0”, this will be unlimited. This can be overridden on a per-connection basis when editing a connection.
By default, per-user concurrent use of connections is unlimited (“0”).
MYSQL_DEFAULT_MAX_GROUP_CONNECTIONS_PER_USER
The maximum number of concurrent connections to allow a single user to maintain to any one Guacamole connection group. If set to “0”, this will be unlimited. This can be overridden on a per-group basis when editing a connection group.
By default, per-user concurrent use of connection groups is limited to one (“1”), to prevent a balancing connection group from being completely exhausted by one user alone.
MYSQL_AUTO_CREATE_ACCOUNTS
Whether or not accounts that do not exist in the MySQL database will be automatically created when successfully authenticated through other modules. If set to “true” accounts will be automatically created. Otherwise, and by default, accounts will not be automatically created and will need to be manually created in order for permissions within the MySQL database extension to be assigned to users authenticated with other modules.
PostgreSQL authentication¶
To use Guacamole with the PostgreSQL authentication backend, you will
need either a Docker container running the postgres
image, or
network access to a working installation of PostgreSQL. The connection
to PostgreSQL can be specified using either environment variables or a
Docker link.
Initializing the PostgreSQL database¶
If your database is not already initialized with the Guacamole schema, you will need to do so prior to using Guacamole. A convenience script for generating the necessary SQL to do this is included in the Guacamole image.
To generate a SQL script which can be used to initialize a fresh PostgreSQL database as documented in Database authentication:
$ docker run --rm guacamole/guacamole /opt/guacamole/bin/initdb.sh --postgres > initdb.sql
Alternatively, you can use the SQL scripts included with the database authentication.
Once this script is generated, you must:
Create a database for Guacamole within PostgreSQL, such as
guacamole_db
.Run the script on the newly-created database.
Create a user for Guacamole within PostgreSQL with access to the tables and sequences of this database, such as
guacamole_user
.
The process for doing this via the psql and createdb utilities included with PostgreSQL is documented in Database authentication.
Connecting Guacamole to PostgreSQL¶
If your PostgreSQL database is provided by another Docker container, and you wish to use a Docker link to connect the Guacamole image to your database, the connection details are implied by the Docker link itself:
$ docker run --name some-guacamole \
--link some-guacd:guacd \
--link some-postgres:postgres \
...
-d -p 8080:8080 guacamole/guacamole
If you are not using Docker to provide your PostgreSQL database, you will need to provide the network connection information yourself using additional environment variables:
POSTGRES_HOSTNAME
The hostname of the database to use for Guacamole authentication. This is required if you are not using Docker to provide your PostgreSQL database.
POSTGRES_PORT
The port that Guacamole should use when connecting to PostgreSQL. This environment variable is optional. If not provided, the standard PostgreSQL port of 5432 will be used.
The POSTGRES_HOSTNAME
and, if necessary, POSTGRES_PORT
environment
variables can thus be used in place of a Docker link if using a Docker link is
impossible or undesirable:
$ docker run --name some-guacamole \
--link some-guacd:guacd \
-e POSTGRES_HOSTNAME=<IP_ADDRESS> \
...
-d -p 8080:8080 guacamole/guacamole
Note that a Docker link to guacd (the --link some-guacd:guacd
option above)
is not required any more than a Docker link is required for PostgreSQL. The
connection information for guacd can be specified using environment variables,
as described in Connecting Guacamole to guacd.
Required environment variables¶
Using PostgreSQL for authentication requires additional configuration parameters specified via environment variables. These variables collectively describe how Guacamole will connect to PostgreSQL:
POSTGRES_DATABASE
The name of the database to use for Guacamole authentication.
POSTGRES_USER
The user that Guacamole will use to connect to PostgreSQL.
POSTGRES_PASSWORD
The password that Guacamole will provide when connecting to PostgreSQL as
POSTGRES_USER
.
If any required environment variables are omitted, you will receive an error message in the logs, and the image will stop. You will then need to recreate the container with the proper variables specified.
Optional environment variables¶
Additional optional environment variables may be used to override Guacamole’s default behavior with respect to concurrent connection use by one or more users. Concurrent use of connections and connection groups can be limited to an overall maximum and/or a per-user maximum:
POSTGRES_ABSOLUTE_MAX_CONNECTIONS
The absolute maximum number of concurrent connections to allow at any time, regardless of the Guacamole connection or user involved. If set to “0”, this will be unlimited. Because this limit applies across all Guacamole connections, it cannot be overridden if set.
By default, the absolute total number of concurrent connections is unlimited (“0”).
POSTGRES_DEFAULT_MAX_CONNECTIONS
The maximum number of concurrent connections to allow to any one Guacamole connection. If set to “0”, this will be unlimited. This can be overridden on a per-connection basis when editing a connection.
By default, overall concurrent use of connections is unlimited (“0”).
POSTGRES_DEFAULT_MAX_GROUP_CONNECTIONS
The maximum number of concurrent connections to allow to any one Guacamole connection group. If set to “0”, this will be unlimited. This can be overridden on a per-group basis when editing a connection group.
By default, overall concurrent use of connection groups is unlimited (“0”).
POSTGRES_DEFAULT_MAX_CONNECTIONS_PER_USER
The maximum number of concurrent connections to allow a single user to maintain to any one Guacamole connection. If set to “0”, this will be unlimited. This can be overridden on a per-connection basis when editing a connection.
By default, per-user concurrent use of connections is unlimited (“0”).
POSTGRES_DEFAULT_MAX_GROUP_CONNECTIONS_PER_USER
The maximum number of concurrent connections to allow a single user to maintain to any one Guacamole connection group. If set to “0”, this will be unlimited. This can be overridden on a per-group basis when editing a connection group.
By default, per-user concurrent use of connection groups is limited to one (“1”), to prevent a balancing connection group from being completely exhausted by one user alone.
POSTGRES_AUTO_CREATE_ACCOUNTS
Whether or not accounts that do not exist in the PostgreSQL database will be automatically created when successfully authenticated through other modules. If set to “true”, accounts will be automatically created. Otherwise, and by default, accounts will not be automatically created and will need to be manually created in order for permissions within the PostgreSQL database extension to be assigned to users authenticated with other modules.
Optional environment variables may also be used to override Guacamole’s default behavior with respect to timeouts at the database and network level:
POSTGRES_DEFAULT_STATEMENT_TIMEOUT
The number of seconds the driver will wait for a response from the database, before aborting the query. A value of 0 (the default) means the timeout is disabled.
POSTGRES_SOCKET_TIMEOUT
The number of seconds to wait for socket read operations. If reading from the server takes longer than this value, the connection will be closed. This can be used to handle network problems such as a dropped connection to the database. Similar to
POSTGRES_DEFAULT_STATEMENT_TIMEOUT
, it will also abort queries that take too long. A value of 0 (the default) means the timeout is disabled.
LDAP authentication¶
To use Guacamole with the LDAP authentication backend, you will need network access to an LDAP directory. Unlike MySQL and PostgreSQL, the Guacamole Docker image does not support Docker links for LDAP; the connection information must be specified using environment variables:
LDAP_HOSTNAME
The hostname or IP address of your LDAP server.
LDAP_PORT
The port your LDAP server listens on. By default, this will be 389 for unencrypted LDAP or LDAP using STARTTLS, and 636 for LDAP over SSL (LDAPS).
LDAP_ENCRYPTION_METHOD
The encryption mechanism that Guacamole should use when communicating with your LDAP server. Legal values are “none” for unencrypted LDAP, “ssl” for LDAP over SSL/TLS (commonly known as LDAPS), or “starttls” for STARTTLS. If omitted, encryption will not be used.
Only the LDAP_HOSTNAME
variable is required, but you may also need to specify
LDAP_PORT
or LDAP_ENCRYPTION_METHOD
if your LDAP directory uses encryption
or listens on a non-standard port:
$ docker run --name some-guacamole \
--link some-guacd:guacd \
-e LDAP_HOSTNAME=<IP_ADDRESS> \
...
-d -p 8080:8080 guacamole/guacamole
Note that a Docker link to guacd (the --link some-guacd:guacd
option above)
is not required. Similar to LDAP, the connection information for guacd can be
specified using environment variables, as described in Connecting Guacamole to guacd.
Required environment variables¶
Using LDAP for authentication requires additional configuration parameters specified via environment variables. These variables collectively describe how Guacamole will query your LDAP directory:
LDAP_USER_BASE_DN
The base of the DN for all Guacamole users. All Guacamole users that will be authenticating against LDAP must be descendents of this base DN.
As with the other authentication mechanisms, if any required environment variables are omitted (including those required for connecting to the LDAP directory over the network), you will receive an error message in the logs, and the image will stop. You will then need to recreate the container with the proper variables specified.
Optional environment variables¶
Additional optional environment variables may be used to configure the details of your LDAP directory hierarchy, or to enable more flexible searching for user accounts:
LDAP_GROUP_BASE_DN
The base of the DN for all groups that may be referenced within Guacamole configurations using the standard seeAlso attribute. All groups which will be used to control access to Guacamole configurations must be descendents of this base DN. If this variable is omitted, the seeAlso attribute will have no effect on Guacamole configurations.
LDAP_GROUP_SEARCH_FILTER
The search filter used to query the LDAP tree for groups that may be used by other extensions to define permissions. If this property is omitted the default of
(objectClass=*)
will be used.LDAP_SEARCH_BIND_DN
The DN (Distinguished Name) of the user to bind as when authenticating users that are attempting to log in. If specified, Guacamole will query the LDAP directory to determine the DN of each user that logs in. If omitted, each user’s DN will be derived directly using the base DN specified with
LDAP_USER_BASE_DN
.LDAP_SEARCH_BIND_PASSWORD
The password to provide to the LDAP server when binding as
LDAP_SEARCH_BIND_DN
to authenticate other users. This variable is only used ifLDAP_SEARCH_BIND_DN
is specified. If omitted, butLDAP_SEARCH_BIND_DN
is specified, Guacamole will attempt to bind with the LDAP server without a password.LDAP_USERNAME_ATTRIBUTE
The attribute or attributes which contain the username within all Guacamole user objects in the LDAP directory. Usually, and by default, this will simply be “uid”. If your LDAP directory contains users whose usernames are dictated by different attributes, multiple attributes can be specified here, separated by commas, but beware: doing so requires that a search DN be provided with
LDAP_SEARCH_BIND_DN
.LDAP_CONFIG_BASE_DN
The base of the DN for all Guacamole configurations. If omitted, the configurations of Guacamole connections will simply not be queried from the LDAP directory, and you will need to store them elsewhere, such as within a MySQL or PostgreSQL database.
As documented in LDAP authentication, Guacamole does support combining LDAP with a MySQL or PostgreSQL database, and this can be configured with the Guacamole Docker image, as well. Each of these authentication mechanisms is independently configurable using their respective environment variables, and by providing the required environment variables for multiple systems, Guacamole will automatically be configured to use each when the Docker image starts.
Header Authentication¶
The header authentication extension can be used to authenticate Guacamole through a trusted third-party server, where the authenticated user’s username is passed back to Guacamole via a specific HTTP header. The following are valid Docker variables for enabling and configuring header authentication:
HEADER_ENABLED
Enables authentication via the header extension, which causes the extension to be loaded when Guacamole starts. By default this is false and the header extension will not be loaded.
HTTP_AUTH_HEADER
Optional environment variable that, if set, configures the name of the HTTP header that will be used used to authenticate the user to Guacamole. If this is not specified the default value of REMOTE_USER will be used.
Custom extensions and GUACAMOLE_HOME
¶
If you have your own or third-party extensions for Guacamole which are not
supported by the Guacamole Docker image, but are compatible with the version of
Guacamole within the image, you can still use them by providing a custom base
configuration using the GUACAMOLE_HOME
environment variable:
GUACAMOLE_HOME
The absolute path to the directory within the Docker container to use as a template for the image’s automatically-generated
GUACAMOLE_HOME
. Any configuration generated by the Guacamole Docker image based on other environment variables will be applied to an independent copy of the contents of this directory.
You will still need to follow the steps required to create the contents of
GUACAMOLE_HOME
specific to your extension (placing the
extension itself within GUACAMOLE_HOME/extensions/
, adding any properties to
guacamole.properties
, etc.), but the rest of Guacamole’s configuration will
be handled automatically, overlaid on top of a copy of the GUACAMOLE_HOME
you
provide.
Because the Docker image’s GUACAMOLE_HOME
environment variable must point to
a directory within the container, you will need to expose your custom
GUACAMOLE_HOME
to the container using the -v
option of docker run
. The
container directory chosen can then be referenced in the GUACAMOLE_HOME
environment variable, and the image will handle the rest automatically:
$ docker run --name some-guacamole \
...
-v /local/path:/some-directory \
-e GUACAMOLE_HOME=/some-directory \
-d -p 8080:8080 guacamole/guacamole
Verifying the Guacamole install¶
Once the Guacamole image is running, Guacamole should be accessible at
http://HOSTNAME:8080/guacamole/
, where HOSTNAME
is the hostname or
address of the machine hosting Docker, and you should see a login screen. If
using MySQL or PostgreSQL, the database initialization scripts will have
created a default administrative user called “guacadmin
” with the password
“guacadmin
”. You should log in and change your password immediately. If
using LDAP, you should be able to log in as any valid user within your LDAP
directory.
If you cannot access Guacamole, or you do not see a login screen, check
Docker’s logs using the docker logs
command to determine if something is
wrong. Configuration parameters may have been given incorrectly, or the
database may be improperly initialized:
$ docker logs some-guacamole

Campaign highlights: DUP attacks Boris Johnson while Labour reveals budget plans
Shadow chancellor John McDonnell said he will deliver a budget on February 5 that will end austerity ‘once and for all’.
Arlene Foster has accused Boris Johnson of breaking his word over his commitment to protect the union between Great Britain and Northern Ireland.
Meanwhile shadow chancellor John McDonnell announced plans for a February budget that will end austerity “once and for all”, and the Lib Dems set out a £100 billion spending plan to tackle climate change.
Here are some of the highlights from Monday’s campaign trail:
– Boris Johnson faces DUP questions over trade within the UK after Brexit
The Prime Minister has been accused of breaking his word over his commitment to protect the union between Great Britain and Northern Ireland by the leader of the Democratic Unionist Party.
Arlene Foster said Government officials had told her there would need to be checks.
She said the DUP had been told by HM Revenue and Customs (HMRC) officials before the PM announced his deal that there would be checks between the mainland and Northern Ireland.
– Labour promises a February Budget to end austerity
Mr McDonnell said he will deliver a budget on February 5 that will end austerity “once and for all”.
Mr McDonnell said his budget would save the NHS, rebuild public services and introduce a real living wage of £10 per hour for all workers over 16.
His budget, he added, will also put more money into an emergency package of reforms to Universal Credit while Labour designs a replacement social security system.
– The Lib Dems have set out a £100 billion spending plan to tackle climate change
The party would aim to generate 80% of electricity from renewables by 2030 and retrofit all homes, targeting those in fuel poverty first by 2025 as part of “our plan for tackling the climate emergency”.
A Lib Dem government would promise to plant 60 million trees a year, ensure all new cars sold are electric by 2030 and ban all non-essential, non-recyclable, single-use plastic within three years.
– Nicola Sturgeon suggests a second EU vote would take place before another Indyref
Scotland’s First Minister has suggested that a fresh referendum on Brexit would be held before a second vote on Scottish independence.
Nicola Sturgeon said that Labour’s intention to hold an EU poll within six months of being elected, with a choice between Remain and a deal negotiated by Jeremy Corbyn, would indicate that a Brexit vote would be first on the ballot.
Ms Sturgeon reiterated her view that another Scottish referendum should be held towards the end of 2020.
– Jo Swinson reveals somebody suggested she should wear lower-cut tops
The Liberal Democrat leader said she has had lots of “unsolicited advice” during the election campaign – including a tip to wear lower-cut tops.
Ms Swinson added she has had people telling her to speak and dress differently, but said she will be “true to myself”.
The Lib Dem leader said the comments were not from within her own team.

The goal of tsrecipes is to provide time series proprocessing to accommodate time series classification and clustering in the tidymodels framework.
The primary steps are
You can install tsrecipes with:
# install.packages("devtools") devtools::install_github("tmastny/tsrecipes")
In time series classification, using the time series as a feature often results in poor accuracy because it’s the auto-correlation between entries and the overall trend that’s the most informative, rather than individual values.
The discrete cosine transform is one way to extract useful, uncorrelated features with significantly fewer dimensions than the time series.
In this example, it’s possible to classify time series of length 1751 into 4 classes with 70% accuracy, only using 16 dimensions.
