What does align-items do in a flex-box?
It defines the default behaviro for how items are laid out along the cross axis. Options are: flex-start, flex-end, center, baseline, stretch.
What does order do in a flex box?
Sets the order of each item. For instance, if you have 5 boxes, you can set one box to be the 5th box which will push the first 4 boxes to the left and this box will be the 5th box.
How does grid layout lay out elements?
This layout style sections off your document into smaller sections that can be organized and customized via the css grid layout properties. Number of rows and columns, and their respective dimensions can be set.
Explain and use the shorthand versions of grid-column and grid-row to define how an element will span a grid layout

What does the overflow CSS property do?
It specifies what should happen if content overflows an element's box. This property specifies whether to clip content or to add scrollbars when an element's content is too big to fit in a specified area.
Does overflow work for all block elements?
No. It only works for block elements with a specified height.
What is a default overflow value?
visible: The overflow is not clipped. It renders outside the element's box if it overflows. This is the default.
What does overflow: hidden do?
If the content is too large to fit in the box, the content that does not fit will not be displayed.

3

CSS
.container {
background-color: #2B2D2F;
position: relative;
}
.element {
display: inline-block;
width: 100px;

font-size: 36px;
}
#element-1 {
background-color: #FFFF00;
}
#element-2 {
background-color: #FF69B4;
position: absolute;
bottom: 60px;
}
#element-3 {
background-color: #00EEEE;
}
Diagram C
What position setting completely removes itself from the document flow, and what is that position dependent upon?
position: absolute;
What position setting will allow you to position the element with (top, bottom, left, right) relative to its normal position?
position: relative
position: relative does not change anything on its own, without setting top, bottom, left, and right.
What is the most common use for position: relative?
Setting the parent element to a non-static value, such that child elements may be positioned relative to this parent. Any non-static setting will allow this, but relative is the most common choice.
If you want to set an element to a specific position on the page, never to have its position interrupted by any other element, what position setting would you choose?
position: absolute
Remember, with position absolute a parent must be set to a non-static setting. If not, the element will be positioned relative to the document root. Also remember, this position setting will allow the element to scroll out of view.
What would you use if you want to lock an element into a specific position, not dependent upon a parent element, which will remain in the same position regardless of scrolling?
position: fixed
Again note: Position fixed is similar to position absolute BUT rather than positioning itself relative to a parent element, it positions itself relative to the document and a specific on-screen position. However, unlike position absolute, when scrolling begins, this element will not move with the scrolling.
What is the default positioning setting?
position: static is default. However, the element set to position static will not be able to be used to position its children.
What position setting initially is relative, but as you scroll it becomes fixed to the top of the page?
position: stickey
This is a combination of both relative and fixed position. While you scroll, this position remains relative. But as you scroll the parent out of view this becomes fixed position, never scrolling out of view.
How do you create a grid?
Set the grid container class's display to grid or inline-grid
How do you put items into the grid?
All direct children of the grid container automatically become grid items.
What are grid container grid settings?
.grid__container {
display: grid;
grid-column-gap: 50px;
grid-row-gap: 50px;
grid-gap: 50px 100px; /* row, column */
grid-template-columns: repeat(4 1fr) /*can use px, or auto or combined to specify number of cols */
grid-template-rows: 80px 200px /* ditto above */
justify-content: space-between; /*space-around, center, start, end, space-evenly */
align-content: space-around; /* space-evenly, space-around, space-betwen, center, start, end */
grid-template-areas: 'area area . . .' /* (template area "area" uses two of 5 cols) */
'area1 area2 area3 area4 area5' /* to name areas used in grid items to indicate where item goes */
}
.grid__item {
grid-column-start: 1;
grid-column-end: 3; //or use
grid-column: 1 / span 3; //start on column 1, span 3 columns
1 / 3; // start on 1, end on 3
grid-row-start: 1;
grid-row-end: 3;
grid-row: 1 / span 3; //start on row 1, span 3 rows;
1 / 3; // start on row 1, end on row 3;
grid-area: area1; // named area related to grid-template-areas on grid__container
1 / 2 / 5 / 6 // ( row start, col start, row end, col end)
}
What are the rules for using a flex box?
What properties are available on a flexible container and on a flex item?
.class__container {
display: flex;
flex-direction: row | row-reverse | column | column-reverse
flex-wrap: nowrap | wrap | wrap-reverse;
flex-flow: column wrap; //shorthand for flex-direction and flex-wrap
justify-content: flex-start | flex-end | center | space-between | space-around | space-evenly | left | start
align-items: flex-start | flex-end | center | stretch | baseline
align-content: flex-start | flex-end ... same as justify content = aligns container's lines within when there is extra space in cross-asix
}
.class_childItem {
order: 1 | 2 | 3 | 5 | ... 99 //default: 0;
flex-grow: 1; //grow twice as large as other containers; 3 times, 4 times, etc.
flex-shrink: 3; //default 1;
flex-basis: | auto /* default auto: default size of elt before remaining space is distrib. 20%, 5rem, auto, etc.
flex: none | [ <'flex-grow'> <'flex-shrink'>? || <'flex-basis'> ] //shorthand for flex-grow, flex-shrink and flex-basis; 2nd & 3rd properties are optional. Defualt is 0 1 auto;
align-self: flex-start | flex-end | auto | center | baseline

This regex extracts the attribute name preceding an attribute-position expression. It does this by matching the syntax allowed for attributes against the string literal directly preceding the expression, assuming that the expression is in an attribute-value position.
See attributes in the HTML spec: https://www.w3.org/TR/html5/syntax.html#attributes-0
"\0-\x1F\x7F-\x9F" are Unicode control characters
" \x09\x0a\x0c\x0d" are HTML space characters: https://www.w3.org/TR/html5/infrastructure.html#space-character
So an attribute is:
An expression marker with embedded unique key to avoid collision with possible text in templates.
An expression marker used text-positions, not attribute positions, in template.
Generated using TypeDoc
A placeholder for a dynamic expression in an HTML template.
There are two built-in part types: AttributePart and NodePart. NodeParts always represent a single dynamic expression, while AttributeParts may represent as many expressions are contained in the attribute.
A Template's parts are mutable, so parts can be replaced or modified (possibly to implement different template semantics). The contract is that parts can only be replaced, not removed, added or reordered, and parts must always consume the correct number of values in their
update()
method.TODO(justinfagnani): That requirement is a little fragile. A TemplateInstance could instead be more careful about which values it gives to Part.update().

If the width factor is greater than one (μ>1), it signifies that the CPMA transfer function is narrower than
the idealized triangular transfer function.
These two factors are determined through multivariate nonlinear functions that are fitted to TCPMA
measurements. The functions take into account either the CPMA mass set point (mp),
CPMA resolution (Rm), and CPMA flow rate (Q), or the CPMA rotational speed (ω) and
voltage (V). If the CPMA flow rate is set to 0.3, 1.5, 4 or 8 LPM, the loss factor is directly
calculated using the fitting function corresponding to the relevant CPMA flow rate. However,
for other flow rates, the loss factor is derived through simple interpolation between the
nearest lower and higher CPMA flow rates.
Under the specified CPMA configuration settings, wherein the width (μ) and height (𝜂) factors of the CPMA transfer function are calculated as below, particles with specified mass exhibit a transmission efficiency of:
The diagram below compares the empirical triangular models with the theoretical triangular, trapezoidal, and diffusion models using the CPMA configuration settings as input. The trapezoidal and diffusion models are alternative transfer functions for CPMA that were derived theoretically by Olfert and Collins (2005) and Sipkens et al. (2020), respectively, based on slightly different assumptions from the triangular transfer function. For instance, the trapezoidal model assumes the axial flow to be parabolic and forces to vary radially, while the diffusion model incorporates particle diffusion into the models. The diffusion and trapezoidal models utilized here correspond to Sipkens et al.'s (2020) study.


'Unicorn' meteor outburst possible Thursday night
by ED PIOTROWSKI | WPDE StaffFLORENCE, S.C. (WPDE) -- A brief and potentially spectacular meteor storm may light up the night sky Thursday night. The "Unicorn" meteor shower that may produce the outburst of activity is formally known as the Alpha Monocerotids. Like all meteor showers, this one gets its name from its radiant point in the constellation Monoceros, which is Greek for "Unicorn".
According to meteor scientists Esko Lyytinen and Peter Jenniskens, up to 400 meteors per hour are possible. While far from a guarantee, they say there's a good chance it will happen.
Unlike most meteor showers that last for many hours, the potential outburst of activity with this shower is short with a duration from as little as 15 minutes to as long as 40 minutes.
The peak of the potential meteor storm is around 11:50 p.m. EST Thursday so experts recommend you get outside by 11:15 p.m EST. Although meteors can be seen in any part of the sky, your best bet is to look east.
Again, there's no guarantee there will be an outburst but there won't be any interference from the moon since it won't rise until after 1 a.m. on the east coast.
If you miss this one, another "Unicorn" meteor storm won't occur until 2043!

SEPARATION ANXIETY
Every fall the scene repeats itself, a lone child screaming and inconsolable, every day for the first few weeks of school. Not only is that child deeply distressed, but he disrupts the teacher and increases the anxiety of all of his classmates as they too attempt to adjust to this new situation. For your child’s benefit and everyone else’s with whom he comes into contact with, please read and put into practice the following suggestions which make the transition from home to school much easier. By taking a few simple steps you can take control and relieve your child’s anxiety.
1) Understand that you and other family members may unknowingly feed your child’s anxiety. When family members are anxious about a child’s school situation, it will transfer to your child. Children naturally pick up on bits and pieces of adult conversations, so remain calm (or appear to be so) and choose your words carefully when discussing school within earshot of your child.
 If you do get to meet his teacher, try to find something cool to point out about her. Perhaps she shares a common interest with your child. Discuss your child’s expectations of school and correct misconceptions by talking about what the school day will be like and reassure him that you’ll be there at dismissal.
3) In elementary school most teachers don’t allow toys or stuffed animals in class. Preschoolers can usually take a stuffed animal or blanket for self-comfort. To compensate, pack a surprise in your child’s lunch box or backpack.
4) If a friend or neighbor’s child has been a student of the teacher, ask that child’s parents if they will have their child speak to yours about the fun activities in that grade. Naturally, try to make sure that the other child had a positive experience in that classroom before speaking to your child.
5) When the first day of school arrives, it’s the parent’s job to be a help, not a hindrance to the teacher. Bring your child into the room, introduce yourselves to the teacher and then leave quietly without a fuss. Children will quickly pick up on a parent’s fear and apprehension.

Welcome to Part 2 of the ensemble Sample Game Tutorial! Now, I'm sure that you're itching to dive into ensemble specifics, but before we get started on that, we're going to be setting up the files we'll be using to just get something appearing on the screen. If you're already comfortabe making your own CSS files for styles and javascript files for storing all of your functions, then you may want to just jump ahead to Part 3.
Okay, still with us? Great! If you haven't tried playing Lovers And Rivals yet on your own, I encourage you to do so--it should be in the folder called sampleGame that came with ensemble. If nothing else, it should help contextualize a lot of what we'll be building in the tutorial. If for whatever reason you'd rather not play it, here's a screenshot to give us all an idea of what the technological marvel we'll be building together looks like:
Clearly, to make something *that* beautiful we're gonna have to get started right away!
We'll start with this, which simply makes the background of the game black, and the text of the game white:
body { background-color: black; color: white; }
Not too bad, right? Next up, we'll be creating the 'field' which is what we'll be calling that rectangle towards the top of the screen.
.field { position: relative; overflow: hidden; width: 530px; height: 30px; border: 3px solid #FFF; }
Inside the field are the three characters whose fates are ensnared in this vicious game of love and rivalry. Let's give our characters some style, shall we?
.character { position: absolute; background-color: black; width: 30px; height: 20px; padding-top: 10px; text-align: center; color: #fff; font-size: 10px; white-space: nowrap; }
And finally, we'll wrap up our CSS file with styles relating to how text should appear on screen.
#titleDiv{ float : left; } #statusDiv{ margin-left : 75px; clear : both; } #actionList_hero_rival{ visibility : hidden; }
And that's all of the styling we have! All told, our CSS file should look a little something like this:
body { background-color: black; color: white; } .field { position: relative; overflow: hidden; width: 530px; height: 30px; border: 3px solid #FFF; } .character { position: absolute; background-color: black; width: 30px; height: 20px; padding-top: 10px; text-align: center; color: #fff; font-size: 10px; white-space: nowrap; } #titleDiv{ float : left; } #statusDiv{ margin-left : 75px; clear : both; } #actionList_hero_rival{ visibility : hidden; }
By this point you should have a lovely little CSS file, that sadly refers to classes and ids that don't yet exist in your game; let's fix that pronto. If you've been following the tutorial from part 1, you should have a file called loversAndRivals.html already at the ready--we'll define all of our html components here, and later on define the functions that operate on those components in a separate javascript file.
Before we forget, we'll quickly add in references to the CSS file we just made, and the javascript file we'll be making shortly that will house all of our game functions. This should go in the head tag at the top of your html file, right after the inclusion of ensemble.js (reprinted here for reference)
 <title>My Fun Game!</title>   <link rel="stylesheet" type="text/css" href="styles.css"> We'll start off by creating a div for the "title" (which will just say "Lovers and Rivals") and the "status" which will update as players take actions, letting them know if they were successful or not. Because the status will be updating dynamically, we'll give it an id as a hook to find it, and ultimately change it, later on in the code. Both of these tags should go immedietely after the body tag you created in part 1 of the tutorial.

Lovers and Rivals!

Click Buttons to win the heart of your love!

Now that we have that, we'll define the field (AKA the big ugly white rectangle) and the characters that are standing in it. The field has a function associated with the onclick event which is largely just for a sanity check we'll reach later on. Note how all three of our characters are associated with the "character" class, but have unique ids: hero, love, and rival. This is also where you can adjust the looks of the characters (but good luck finding something more heroic than \O/ or more evil than @.o).

 \O/

 0\

 @.o

Now that we're displaying our characters, it's time to display the potential actions the characters can take towards each other. This area won't be populated with data until we hook our game up with ensemble, but there's nothing stopping us from setting up the skeleton for now. It's also worth noting that in the version of the game for this tutorial, the Hero character is the only character who takes actions, and they can only take actions towards the Love character, or towards themselves. Making the hero capable of taking actions towards the Rival, or allowing the Love and Rival to take actions as well, are all excellent ways for you to make Lovers and Rivals truly your own! But, I digress...

 What to do on turn 0:
 Towards Love:

 Towards Yourself:

Up next we have a div that displays relevant state information to the player. In a game one might be so bold as to label "better" than Lovers and Rivals, this state information would be seamlessly and cleverly integrated into the game itself, instead of just being a bunch of numbers uncouthly shoved in the player's face. But for now, a big list is what you and your players are going to get. As with the action list, the actual values will be filled in later with the help of ensemble, using the placeholder NA to start.

Social State

Closeness

Hero to Lover: NA

Lover to Hero: NA

Lover to Rival: NA

Attraction

Hero to Lover: NA

Lover to Hero: NA

Lover to Rival: NA

Hero Attributes

Strength: NA

Intelligence: NA

And that's the basic structure of your html file! We will come back to it later once we start actually using ensemble, but by this point you should be able to load up your html file and have something that is beginning to resemble that screenshot at the top of the page appear on your very own screen. For reference, this is what your html file should look like now (complete with what you already created in part 1).
  <title>My Fun Game!</title>   <link rel="stylesheet" type="text/css" href="styles.css">

Lovers and Rivals!

Although there's nothing stopping you from defining all of your functions inside of a script tag in your html file, I prefer to separate them out into a file of their own. This file is gonna have a lot of stuff in it, and Part 2 of this tutorial is already running a little long. To that end, for now we'll just do the minimum to ensure that all of our files are capable of talking to each other.
Make yourself a new javascript file, lets call it loversAndRivals.js, and fill it up with a couple of objects that will store state and game data.
var stateInformation = { "loveToHeroCloseness" : "NA", "loveToHeroAttraction" : "NA", "heroToLoveCloseness" : "NA", "heroToLoveAttraction" : "NA", "loveToRivalCloseness" : "NA", "loveToRivalAttraction" :"NA", "heroStrength" : "NA", "heroIntelligence" : "NA" }; var gameVariables = { "gameOver" : false, "endingText" : "NA", "turnNumber" : 0, "numIntents" : 2, "numActionsPerIntent" : 5 };
You may notice that most of that data doesn't look too terribly interesting -- don't worry! As we continue, this data will be updated with knowledge from ensemble.
Now would be a good time to point out that there are better ways to work with javascript, such as the module pattern, than what we're using here. What we're doing here is the quickest, dirtiest way to get something up and running. You are more than welcome to fix the code up as much as you like, on your own time!
And lastly, we'll create that move function we referenced when defining the field. This should move the hero character, by first grabbing a reference to the html hero element through a call with document.getElementById("hero"), setting up an interval that will call the defined frame function every ten millesconds, which itself will update the hero's position by incrementing its left property. This continues until left reaches 100, at which point the interval is removed, ceasing the hero's movement. All this should happen when the player clicks on the field.
var move = function(){ var elem = document.getElementById("hero"); var left = 0; function frame() { left++; // update parameters elem.style.left = left + 'px'; if (left == 100) { clearInterval(id); } } var id = setInterval(frame, 10); // draw every 10ms };
And that'll do it for now! Though we'll revisit it soon, our javascript file should look a little something like this:
var stateInformation = { "loveToHeroCloseness" : "NA", "loveToHeroAttraction" : "NA", "heroToLoveCloseness" : "NA", "heroToLoveAttraction" : "NA", "loveToRivalCloseness" : "NA", "loveToRivalAttraction" :"NA", "heroStrength" : "NA", "heroIntelligence" : "NA" }; var gameVariables = { "gameOver" : false, "endingText" : "NA", "turnNumber" : 0, "numIntents" : 2, "numActionsPerIntent" : 5 }; var move = function(){ var elem = document.getElementById("hero"); var left = 0; function frame() { left++; // update parameters elem.style.left = left + 'px'; if (left == 100) { clearInterval(id); } } var id = setInterval(frame, 10); // draw every 10ms };
Okay, if you've been following along, opening up your loversAndRivals.html file should display a screen that looks a little something like this:
And clicking on the field should make your little hero ( \0/ ) appear and take a few steps forward. Right now they are kinda being covered up by the Love and the Rival, but don't worry. We'll make sure the hero has a nice personal bubble's worth of space in future parts of the tutorial. Congratulations! We've now gotten most of the grunt work out of the way, and are now ready to start defining the social parts of our social world!
Feeling good? Good! Time to move on to Part 3!

PeepholeLSTMCell
Equivalent to LSTMCell class but adds peephole connections.
Inherits From: LSTMCell
tf.compat.v1.keras.experimental.PeepholeLSTMCell
tf.compat.v2.keras.experimental.PeepholeLSTMCell
Peephole connections allow the gates to utilize the previous internal state as well as the previous hidden state (which is what LSTMCell is limited to). This allows PeepholeLSTMCell to better learn precise timings over LSTMCell.
From Gers et al.:
"We find that LSTM augmented by 'peephole connections' from its internal cells to its multiplicative gates can learn the fine distinction between sequences of spikes spaced either 50 or 49 time steps apart without the help of any short training exemplars."
The peephole implementation is based on:
Long short-term memory recurrent neural network architectures for large scale acoustic modeling.
# Create 2 PeepholeLSTMCells peephole_lstm_cells = [PeepholeLSTMCell(size) for size in [128, 256]] # Create a layer composed sequentially of the peephole LSTM cells. layer = RNN(peephole_lstm_cells) input = keras.Input((timesteps, input_dim)) output = layer(input)
__init__
__init__( units, activation='tanh', recurrent_activation='hard_sigmoid', use_bias=True, kernel_initializer='glorot_uniform', recurrent_initializer='orthogonal', bias_initializer='zeros', unit_forget_bias=True, kernel_regularizer=None, recurrent_regularizer=None, bias_regularizer=None, kernel_constraint=None, recurrent_constraint=None, bias_constraint=None, dropout=0.0, recurrent_dropout=0.0, implementation=1, **kwargs )
get_dropout_mask_for_cell
get_dropout_mask_for_cell( inputs, training, count=1 )
Get the dropout mask for RNN cell's input.
It will create mask based on context if there isn't any existing cached mask. If a new mask is generated, it will update the cache in the cell.
inputs
: the input tensor whose shape will be used to generate dropout
mask.training
: boolean tensor, whether its in training mode, dropout will be
ignored in non-training mode.count
: int, how many dropout mask will be generated. It is useful for cell
that has internal weights fused together.List of mask tensor, generated or cached mask based on context.
get_initial_state
get_initial_state( inputs=None, batch_size=None, dtype=None )
get_recurrent_dropout_mask_for_cell
get_recurrent_dropout_mask_for_cell( inputs, training, count=1 )
Get the recurrent dropout mask for RNN cell.
It will create mask based on context if there isn't any existing cached mask. If a new mask is generated, it will update the cache in the cell.
inputs
: the input tensor whose shape will be used to generate dropout
mask.training
: boolean tensor, whether its in training mode, dropout will be
ignored in non-training mode.count
: int, how many dropout mask will be generated. It is useful for cell
that has internal weights fused together.List of mask tensor, generated or cached mask based on context.
reset_dropout_mask
reset_dropout_mask()
Reset the cached dropout masks if any.
This is important for the RNN layer to invoke this in it call() method so that the cached mask is cleared before calling the cell.call(). The mask should be cached across the timestep within the same batch, but shouldn't be cached between batches. Otherwise it will introduce unreasonable bias against certain index of data within the batch.
reset_recurrent_dropout_mask
reset_recurrent_dropout_mask()
Reset the cached recurrent dropout masks if any.
This is important for the RNN layer to invoke this in it call() method so that the cached mask is cleared before calling the cell.call(). The mask should be cached across the timestep within the same batch, but shouldn't be cached between batches. Otherwise it will introduce unreasonable bias against certain index of data within the batch.

SAML Proxy End to End Configuration and Testing
For this testing environment we have below pieces:
- https://sp.gluu.org/protected/print.py –> Service Provider
- https://test.gluu.org –> Gluu Server with SAML Script and Asimba
- https://nest.gluu.org –> Gluu Server acting as remote authentication server
The whole workflow is:
SP1 (sp.gluu.org) → IDP (test.gluu.org) → oxAuth Saml script (test.gluu.org) → Asimba (test.gluu.org) → Remote IDP (nest.gluu.org) → oxAuth (test.gluu.org / any acr_values) → back_in reverser_order

- How to create nameID in Gluu Server is available
Preparation in Service Provider (SP)
Server: https://sp.gluu.org
Preparing Service Provider for SAML Proxy worflow follows standard procedure. Service Provider need to connect with Gluu Server's Shibboleth part ( for our case, the entityID would be: https://test.gluu.org/idp/shibboleth ). How to configure any site with Shibboelth SP piece is available here.
Test
Here is a quick video on how SAML Proxy SSO might look like. Here in this video we are using 'https://sp.gluu.org/protected/print.py' as our protected service provider link. After initiating the SSO, we are moved to Gluu Server's SAML Proxy discovery page ( https://test.gluu.org ). From there we selected 'Nest' as our desired authentication server. After succesful authentication we are landing to proctected resource. https://youtu.be/YEyrOWJu0yo

(see http://www.ogre3d.org/tikiwiki/Basic+Tutorial+1&structure=Tutorials) The coordinate system is centered with 0,0,0 in the exact center of the game world. Orientation is stored as a quaternion with <0, 0, -1> as the base heading (to correspond with the default for Ogre cameras, scene nodes, etc.)

Most of the time indigestion is not a serious disorder. But sometimes it can be a symptom of a heart attack. Though it is more often serious when associated with other symptoms, as listed above, it can still be the red light warning signal of a heart attack when it appears alone.
Under the above circumstances an immediate visit to the emergency room may save your life.
The tube that carries food from your mouth to your stomach is called the esophagus. When food backs up from the stomach into the esophagus (reflux) and the esophagus becomes irritated, you may develop heartburn. This condition often responds to an antacid or ulcer medication. However, if you have heartburn for weeks and it does not respond to conventional treatment, it is important to have it evaluated by your doctor.

Why is a metadata standard important? Publishing your metadata in a recognised standard inspires trust, enables new services, and opens up international opportunities.
“GEMINI” is the UK geographic metadata standard. It provides guidance on how to publish geographic metadata in a way that conforms to relevant ISO standards and the UK’s implementation of the European INSPIRE regulations.
UK GEMINI (GEo-spatial Metadata INteroperability Initiative) is a specification for a set of metadata elements for describing geospatial data resources. It has been produced and is maintained by the Standards Committee. It is provided free of charge by the AGI for the benefit of the GI community, under a Creative Commons license.
If you're thinking, "why GEMINI? Why not just use the INSPIRE Metadata guidance or the ISO standards?" Click here for some reasons.

This revision incorporates material prepared by the UK Location Programme, previously published at data.gov.uk, and material previously published as separate guidance documents. We hope this consolidation will make it easier for you to use. GEMINI has also been updated for change requests from revised INSPIRE guidance and UK users. The AGI is grateful to Defra for funding part of this work, and for several AGI members also contributing.
The existing guidelines on the quality of metadata still apply: Guidelines for UK GEMINI Part 3 Metadata Quality
UK INSPIRE announced their intention to require data publishers to migrate to GEMINI 2.3 by December 2019, in line with the target date from Europe for adopting the current version of their INSPIRE Technical Guidance. However, technical implementations have been delayed. UK INSPIRE, and the data.gov.uk system in particular, will continue to accept GEMINI 2.2 records encoded according to UK Location guidance, at least until then - although they may generate warning messages from the EU portal.

This is a KNN algorithm implementation written in Matlab. In this example, I’m just using some random numbers for X, Y, and the according labels. There are 3 classes differentiated by color.
For the distance I chose Euclidean distance. The algorithm loops through all records in the dataset, finds K closest neighbor points, and predict using the most occurring label.
In this example, I’m only running the algorithm against the training dataset. Therefore, for each iteration in the loop I need to avoid counting the record itself as a neighbor.
%Setting up X, Y, Classes, and K values, etc.
trainX = a(:,1:2);
trainY = a(:,3);
classes = unique(trainY);
n = size(trainY,1);
output = zeros(n,1);
klist = [1,2,5,20];
label = {'ro','b+','g*'};
%Use L2 distance method for the training data
for i=1:n
distL2(i,:) = sum((trainX - ones(n,1)*trainX(i,1:2)).^2,2);%calc L2 distance
distL2(i, i) = max(distL2(i,:))+1;%leave out the row with same index
[j, ind] = sort(distTrL2(i,:)); %sort the distances
%get the k nearest neighbors and choose the most occurring class
for j=1:length(klist)
k=klist(j);
neighbors = trainY(ind(1:k));
predTrain2(i,j) = mode(neighbors);
end
end
resultTr2 = [trainX, predTrain2];
figure(1); hold off
subplot(2,2,1)
for i = 1:length(classes)
pos = find(resultTr2(:,3)==classes(i));
plot(resultTr2(pos,1),resultTr2(pos,2),label{i})
hold on
end
title(sprintf('K = %g',1));
subplot(2,2,2)
for i = 1:length(classes)
pos = find(resultTr2(:,4)==classes(i));
plot(resultTr2(pos,1),resultTr2(pos,2),label{i})
hold on
end
title(sprintf('K = %g',2));
subplot(2,2,3)
for i = 1:length(classes)
pos = find(resultTr2(:,5)==classes(i));
plot(resultTr2(pos,1),resultTr2(pos,2),label{i})
hold on
end
title(sprintf('K = %g',5));
subplot(2,2,4)
for i = 1:length(classes)
pos = find(resultTr2(:,6)==classes(i));
plot(resultTr2(pos,1),resultTr2(pos,2),label{i})
hold on
end
title(sprintf('K = %g',20));
Here are the plots generated. As the K values goes higher, the boundaries between classes becomes smoother.

a communication-aide for non-verbal kids
Pic-A-Talk is a communication-aide specially created for verbally-challenged children, usually low-functioning autistic kids. These children think in pictures, they learn better when they see an image associated with the word, so this application contains images of things children are usually interested in as well as an audio for each image. If a child is interested in an item, they click it and an audio associated with that object is played. Not only does this help them in communicating with other people, it is also a learning experience since they are exposed to the word and image. Every click is then recorded for the parent's further monitoring of their child's activities.

--- layout: post title: Must follow C rules, no exceptions date: 2023-02-09 13:00:00 keywords: nativeaot teaser: Error handling for a Native AOT library needs special attention ord: 09200 ---
This is part of a series on Native AOT.
Previous -- Top -- Next
As we have said, functions exported by a Native AOT library must follow the rules of C, and that means exceptions cannot be thrown. More specifically, it means that if we attempt to throw an exception past the Native AOT function boundary, the program will crash. C doesn't have exceptions, so it can't deal with them.
Once again, here's the code for a Native AOT function to get the length of a string:
[UnmanagedCallersOnly(EntryPoint = "get_string_length")] public static int GetStringLength(IntPtr v) { GCHandle h = GCHandle.FromIntPtr(v); object ob = h.Target; string s = (string) ob; int len = s.Length; return len; }
As trivial as this code is, it does have places an exception might get
thrown. In fact, we did that intentionally in the previous chapter
by passing in an invalid GCHandle
.
What should we do about this? We basically have only two options. We can allow the exception to cause a crash, or we can catch the exception and somehow propagate the error.
For this particular function, we might actually just want to leave it alone. Some errors can't be usefully handled. As far as I can tell, aside from memory corruption, the only way this function can crash is when it was given an invalid argument, which suggests a bug somewhere else that should be found and fixed.
But that won't work in every scenario. In many cases, the body of a Native AOT function might need to look something like this:
[UnmanagedCallersOnly(EntryPoint = "my_function")]
public static int my_function()
{
try
{
// do something
return 0; // 0 means no error
}
catch (Exception e)
{
return -1; // TODO some kind of meaningful error code
}
}
There are a myriad of choices here, but the basic point is that we would need to decide how we want to represent errors, catch exceptions, and return those exceptions in the representation we chose. In this example I chose the commonly used approach of an integer error code, but I do not wish to imply that this would be simple. Error handling rarely is.
Let's pretend for a moment that we actually do want our string length function to catch and propagate. How would do that? If we want to return an error code, we now have two return values, since the function already wants to return the string length. One or both of these values are going to need to be returned through a pointer parameter (C rules, remember?).
Let's propagate the error code through a pointer
(which requires unsafe
):
[UnmanagedCallersOnly(EntryPoint = "get_string_length_errcode_parm")]
public unsafe static int WithErrorCodeParm(IntPtr v, int* ptr_error_code)
{
try
{
GCHandle h = GCHandle.FromIntPtr(v);
object ob = h.Target;
string s = (string) ob;
int len = s.Length;
*ptr_error_code = 0; // no error
return len;
}
catch (Exception e)
{
*ptr_error_code = -1; // TODO meaningful error code
return -1; // TODO but what result should we return?
}
}
One problem here is that we still have to return something for the result even when the exception is caught. A string length cannot be less than zero, so we just return something invalid.
Hey, maybe this function doesn't need the error code to be separate? Couldn't we just make all our error codes negative and thus store the length and the error code in the same number? In this case, sure, that'll work:
[UnmanagedCallersOnly(EntryPoint = "get_string_length_neg")] public static int AsNegativeLength(IntPtr v) { try { GCHandle h = GCHandle.FromIntPtr(v); object ob = h.Target; string s = (string) ob; int len = s.Length; return len; } catch (Exception e) { return -1; // TODO meaningful negative error code } }
But that certainly won't work in all cases. This function just happens to have a return type that isn't using all its possible values.
And either way, the caller of this function now has to actually deal with error conditions. It needs to check for a negative length, or it needs to check that separate error code. There is not much reason to propagate errors and then ignore them.
And that brings us full circle to the realization that error propagation for this particular function is a cure that is worse than the disease.
Broadly speaking, error handling is a very complex topic. For now, my intent is merely to scratch the surface, and to observe that Native AOT libraries bring error handling challenges that many .NET developers will find unfamiliar.
In typical .NET development:
We don't need to decide how to represent errors,
because System.Exception
is the standard
way to do that.
The decision of whether to propagate error information does not affect the signature of a method, because exceptions can be thrown from anywhere.

I'll close with one more thing. Even with Native AOT,
we could maaaaaybe stay with System.Exception
as the standard way of propagating error information.
Using a GCHandle
, we can return exception
objects -- we just can't throw them.
[UnmanagedCallersOnly(EntryPoint = "get_string_length_ex_parm")]
public unsafe static int WithExceptionParm(IntPtr v, IntPtr* ptr_ex)
{
try
{
GCHandle h = GCHandle.FromIntPtr(v);
object ob = h.Target;
string s = (string) ob;
int len = s.Length;
*ptr_ex = IntPtr.Zero; // no error
return len;
}
catch (Exception e)
{
*ptr_ex = GCHandle.ToIntPtr(GCHandle.Alloc(e));
return -1; // TODO but what result should we return?
}
}
That solves only one of our problems (and not
one of the more difficult ones). And it raises
more problems of its own: Object handles are opaque,
so in order to turn that Exception
object into
any sort of useful information, we'll have to make
another trip across the Native AOT boundary, and,
well, what happens if an exception gets thrown while
trying to get information about the exception that
got thrown?

- Prioritization: Working with company leadership, including the C-suite, to identify the highest ROI projects
- Product Development and Testing: Collaborating with Product and Engineering as a statistics expert on A/B tests
- Product Launch: Building out reporting to monitor the adoption and health of a feature in the wild
- Customer Behavior: Conducting in-depth analysis of our customers and how they interact with our existing product
As part of a small team, you’ll occasionally take on generalist analytics projects outside of Product, for example, related to customer service or merchant success. This will originally be an individual contributor role, however, there may be opportunities to manage other analysts as the team grows.
Qualifications
- 2-4 years of experience analyzing product or customer data at a software company
- BA in a quantitative field: Stats, Finance, Economics, Math, or Computer Sciences are preferred
- Fluency in SQL
- Some experience in least one functional programming language, especially R or Python
- A working knowledge of statistics, i.e. confidence intervals and linear regression
- Experience with funnels and event tracking software, i.e. Heap or Mixpanel
- Strong interpersonal skills
Bonus Points
- An advanced degree
- Experience in financial services or credit
- Experience with both B2B and B2C data
- Experience with any of our specific analytics stack: Redshift, Postgres, R, Github, Heap, Looker, Zendesk, and Salesforce
- Experience with survey data and software
- Familiarity with an agile working environment
