TILL THERE WAS YOU 1997 A film review by Timothy Voon Copyright 1998 Timothy Voon 2 :-( :-( for all the others before you
Cast: Jeanne Tripplehorn, Dylan McDermott, Sarah Jessica Parker, Jennifer Aniston, Craig Bierko, Steve Antin, Patrick Malahide, Karen Allen Director: Scott Winant Screenplay: Winnie Holzman
This movie should have been more aptly titled, ‘ALL THE OTHER PEOPLE I HAD SEX WITH, UNTIL THERE WAS YOU.'
Gwen Moss (Jeanne Triplehorn), had always thought that her parents were the perfect couple. She imagined that when she grew up, she would meet the man of her dreams and like her parents, live her life in perfect marital bliss. Boy was she wrong.
 The second was `Right', a dashing publicist for the rich and famous, that was until she found out he was obsessed with someone else. The third was `Perfect', a childhood sweetheart running for mayor, that was until she found out he cared more about his career than her. All of these men, TILL THERE WAS YOU.
Nick Dawkan (Dylan McDermott), came from a broken home rife with parental discord. Like everyone else, he was searching for true love.
His first love was purely `Sexual', a college sweetheart and we know that a relationship based on sex, doesn't last. The second had great `Looks', but that doesn't last either. The third was the result of a childhood crush on a TV star (Sarah Jessica Parker). Immeasurable expectations only breeds immeasurable disappointment, when the real person does not live up to her on screen persona. All of these women, TILL THERE WAS YOU.
So when Nick and Gwen meet over a cigarette, outside a Smoker's Anonymous meeting room, how do we know they are right for each other? They could simply be number four in the long line of sexual contacts. A relationship based purely on ‘we share something in common' (loneliness and smoking), does not necessarily equate to true love. This is the movie's major flaw. We are shown why their other relationships failed, but we aren't shown why they are right for each other. They meet, they look compatible, they have some common interests i.e. poetry, old buildings, but this could simply be a prequel for a one-night-stand, and not the precursor for a long lasting relationship.
Unfortunately, this is not the movie that will launch Jeanne Tripplehorn or Dylan McDermott into the greater public eye. Sarah Jessica Parker, is as usual, entertaining as the ex-childhood TV star.

Our services provides data around Fish Aggregating Devices (FAD). Big data is a very important concept nowadays, it is used in analysis, machine learning, modeling etc. However, for most people who want to use the convenience of the data, they often have questions -- where and how could I find and use the data? That is why we are here to help!
Automatically upload datasets to Azure Storage
Search the data in Azure by keywords or labels
Display the data by maps, graphs or tables
Nowadays, critical conservational and sustainability research is conducted for ecosystem monitoring, species tracking, pollution detection. But many of these projects fail due to technology skill gap or development cost. For the implementation of a Fishing Aggregating Device within Saint Lucia, data scientists can't easily find or connect to meaningful data. As a result, end-users can lose FADs in the ocean.
Our solution aims to accelerate the workflow of scientists. It downloads ocean data, processes and parses it into CSV or JSON formats. Datasets are then filtered to be specific to Saint Lucia and loaded into an Azure storage account. From this point, conservationists can connect to it with a few mouse clicks and generate faster analytics, machine learning models, better charts and map visualizations.
For our outputs, information such as FADs' locations or Temperature of FADs can be presented to end-users intuitively, resulting in more efficient usage of data. To give an example, our progressive web app can displays trustworthy analytics and maps visualizations of FADs. By these idiomatically approaches, data scientists are able to perform better when working with data of FADs.

Handles the connection and communication with a SignalR hub. May wrap many `<pacem-hub-listener>` elements that specifically handle messages pushed by the hub.


Responsive site is a site that adapt to the screen size of the device used to view the site. It is important for good user experience. Most users do not want to scroll multiple times (especially sideways) to view the whole site. Also the interaction can be different depend on the device. For example, on mobile device users need to touch the screen to navigate while on desktop/laptop users use cursor moved by a device i.e. mouse
Mobile first design is to acknowledge that it is more difficult to design a site for mobile where the screen size is limited. Thus it is best to design for a mobile first and then adapt for larger screens where it is easier to add more elements.
Frameworks are pre existing set of code that can added to your site so you can re-use them. The pro of frameworks are it can make your work easier and faster since you don't need to rewrite them. The cons are it can contain code that you don't need to use so depending on it size it can slows the loading time. For example, Bootstrap frameworks offers more functionality than Skeleton frameworks but it is also bigger in size.
Wireframe is an initial design using sketch or simple graphics to represent the layout of a page. It is used to developing the layout and structure of a webpage without all the fonts, colors that can distract. It is also important to provide initial scope of the project to avoid project's creep.
My wireframes for mobile index and blog pages:
My wireframes for desktop index and blog pages:
My wireframes is initially design to play round with elements' position using css but I found it hard to implement with the current CSS knowledge that I have.

Quantum channel tomography¶
One can open this notebook in Google Colab (is recommended)
In the given tutorial, we perform quantum channel tomography via the manifold of Choi matrices. First of all, let us import some libraries.

Many-qubit, informationally complete, positive operator-valued measure (IC POVM)¶
Before generating measurement outcomes and performing quantum tomography, one needs to introduce POVM describing quantum measurements. For simplicity, we use one-qubit tetrahedral POVM and generalize it on a many-qubit case by taking tensor product between POVM elements, i.e. \(\{M_\alpha\}_{\alpha=1}^4\) is the one-qubit tetrahedral POVM, \(\{M_{\alpha_1}\otimes \dots \otimes M_{\alpha_N}\}_{\alpha_1=1,\dots,\alpha_N=1}^4\) is the many-qubits tetrahedral POVM.

Data set generation (measurement outcomes simulation).¶
Here we generate a set of measurements (training set). First of all, we generate a random quantum channel with Kraus rank 𝑘 by using the Stinespring representation of a quantum channel. Then we generate a set of random pure density matrices pass them trough the generated channel and simulate measurements of output states. Results of measurements and initial states we write in a data set.

Optimization loop¶
Here we perform maximization of the logarithmic likelihood. In order to preserve constraints of a quantum channel, we use the manifold of Choi matrices. The manifold of Choi matrices is imlemented through a special parametrization. Any Choi matrix \(\rho\) is represented by a matrix \(A\), where \(\rho = AA^\dagger\). Then Choi matrix is non-negative by construction. One also needs to require the corresponding quantum channel to be trace preserving, it is atchieved by imposing the additional constraint \({\rm Tr}_2(\rho) = {\rm Tr}_2(AA^\dagger) = I\), where \({\rm Tr}_2\) is a partial trace and \(I\) is the identity matrix. Since there is an equivalence \(A\sim AQ\), where \(Q\) is an arbitrary unitary matrix, optimization is performed on the quotient manifold eliminating this simmetry. The corresponding quotient geometry is described in
Yatawatta, S. (2013, May). Radio interferometric calibration using a Riemannian manifold. In 2013 IEEE International Conference on Acoustics, Speech and Signal Processing (pp. 3866-3870). IEEE.

Struct entitypool::EntityPool
[−]
[src]
pub struct EntityPool { // some fields omitted }
Methods
impl EntityPool
fn new() -> EntityPool
Creates a new, empty EntityPool
.
The EntityPool
will not allocate until entities are created.
fn with_capacity(create_capacity: usize, return_capacity: usize) -> EntityPool
Creates a new, empty EntityPool
with the specified capacities.
The EntityPool
will able to create create_capacity
and return return_capacity
entities without reallocating. If either capacity is 0, their respective storage
vectors will not allocate.
fn create_entity(&mut self) -> (usize, Entity)
Creates a unique entity.
Returns the Entity
and it's current index
. The index is only guaranteed to remain
valid until the next call to return_entity
.
fn return_entity(&mut self, entity: Entity)
Release ownership of the entity
, allowing for it to be recycled. A recycled entity will
have it's internal generation incremented, yielding a new, unique entity.
Entities are stored in contiguous memory. When an entity is returned, the last entity is swaped into the returned entity's slot; thus indexes retrieved prior to returning an entity are potentially invalidated.
Panics
Returning an entity more than once, or an entity created from another pool, results in undefined behavior.
Examples
use entitypool::EntityPool; let mut pool = EntityPool::new(); let (_, e1) = pool.create_entity(); pool.return_entity(e1); let (_, e2) = pool.create_entity(); assert!(e1 != e2);
use entitypool::EntityPool; let mut pool = EntityPool::new(); let (i1, e1) = pool.create_entity(); let (i2, e2) = pool.create_entity(); let (i3, e3) = pool.create_entity(); assert_eq!(0, i1); assert_eq!(1, i2); assert_eq!(2, i3); assert_eq!(0, pool.index_of(e1)); assert_eq!(1, pool.index_of(e2)); assert_eq!(2, pool.index_of(e3)); pool.return_entity(e2); assert_eq!(0, pool.index_of(e1)); assert_eq!(1, pool.index_of(e3));
fn index_of(&self, entity: Entity) -> usize
Returns the current index
of the given entity
, which is only guaranteed to remain
valid until the next call to return_entity
.
Panics
Querying the status of an entity from another pool results in undefined behavior.
fn entity_at(&self, index: usize) -> Entity
Returns the current entity
at the given index
.
Panics
Panics if the index is greater or equal to the number of live entities in this pool.
fn is_alive(&self, entity: Entity) -> bool
Returns true
if this entity has not been returned.
Panics
Querying the status of an entity from another pool results in undefined behavior.
fn iter(&self) -> Iter<Entity>
Returns an iterator to the live entities. The Enumerate
of the returned iterator will
yield each entity
and its current index
.
Examples
use entitypool::EntityPool; let mut pool = EntityPool::new(); pool.create_entity(); pool.create_entity(); pool.create_entity(); for (index, entity) in pool.iter().enumerate() { assert_eq!(index, pool.index_of(*entity)); assert_eq!(*entity, pool.entity_at(index)); }
fn reset(&mut self)
Resets the EnitityPool

How does the world wide web work?
Clients, servers, responses, requests
The Internet and the Web
Browsers
Developers (namely, front-end developers) have to decide which browsers they want their webpages to look the best in.
Browser stats
Front-End vs. Back-End
Front-End
Code is rendered by the client (your browser)
Describes content, presentation, and behavior
Examples: HTML, CSS, JavaScript
Back-End
Code is interpreted on the server
Handles, data stores, state, business logic
Passes content to the front-end before rendering in the browser

Web Development Workflow
The website goes through several interations between UX and Design, I am delivered design files
Use HTML, CSS, and JavaScript to code the page to the client specs
Besides "how it looks", Front-End developers must consider accessibility, performance, cross-browser and cross-device functionality
HTML: Hypertext markup language
What is HTML?
Establishes the structure of a webpage
Describes the page's content in a way that the browser can format
HTML is made up of "tags" that surround the pieces of our content to describe what it is
HTML Syntax
Headline Tag
I'm a Large Headline!
Opening Tag
Closing tag with backslash
Desired content between
HTML Intro Codealong
As we learn some of the most commonly used tags you will practice along in codepen to see the tags come to life - and the default styles and behavior from the browser.
First tag:
Type any headline you want!
6 Headline Sizes
Most Important Headline
2nd Most Important Headline
3rd Most Important Headline
4th Most Important Headline
5th Most Important Headline
Least Important Headline
Try each in codepen. Look at the different sizes the browser gives to each one.
Paragraph Tag
I'm a paragraph. I'm a block of text with sentences.
I want to break it up!
No closing tag. Should only be used on copy.
Place a br tag in your paragraph.
Nesting Tags
HTML is hierarchical and can be nested.
Check out this code for an "ordered list".
This is an ordered list!
You will see numbers, in order.
I'm the third item on the list
Okay, but what if I don't want numbers?
UNordered list to the rescue!
This is an ordered list!
Look at those numbers, in order!
I'm the third item on the list
Tags with attributes
Image Tag
property="value"
src attribute
no closing tag
Try in codepen, with source "http://lorempixel.com/400/200"
Explore, add, subract, or even "break" this page with any tags you'd like to practice with (10 minutes)
Idea: Could you create a linked image?
Idea: Research and try other tags like header, footer, article, section, etc.
Semantic html tags vs. semantic-less html tags
Semantic tags are what they say they are. You shoud avoid using inaccurate tags. Examples include article, footer, header, main, nav, section, aside, etc.
Semantic-less tags are used purely for the sake of the developer to section content off for styling. Examples: div, span.
HTML DOCUMENT SYNTAX
Why is this important?
Codepen is great for quick practicing, but when writing our own HTML pages we will need to follow a typical html document structure so the browser knows it's an HTML doc.
Boilerplate HTML
<!DOCTYPE html>

<meta charset="utf-8">
<title>My Webpage</title>

Hello world

All of the tags we just practiced go between the
body tags.

What new tags do you see? Let's learn what they each do...
Tag
Usage
Notes
doctype
<!DOCTYPE: html>
Tells the browser that the document is HTML5. Should be the first tag in the document.
html

Parent element for all other elements on the page.
head

Parent element of all the metadata-nothing here is rendered on the screen, it's all for the browser.
body

Parent element of page content. All tags we just practiced would go between these tags, and would get rendered to the screen.
Meta Tags
Tag
Usage
Notes
title
<title>
Sets the title for the web page. Rendered by the web browser in the tab, and by search engines.
meta
<meta>
Can set various metadata attributes of the page,such as character set.
HTML document codealong
Create Our Project Structure
Create a new folder on your desktop and call it My Website
Open Atom, and open a new untitled document
Save the document as "index.html"
Type the following code exactly as you see, double checking for syntax and spelling typos.
<!DOCTYPE html>

<meta charset="utf-8">
<title>My Webpage</title>

Hello world

This is where all your content goes.

Test the setup
Save your code
Open your My Webpage Folder, and then open your index file. (You may need to right click and "Open With...Chrome")
A Chrome browser window should open and you should see your headline and paragraph. Woohoo!
Something not right? Debug!
HTML Content Lab
Start creating website about anything you want, using the following tags:
1 H1 Tag, 2 other H tags
2 links
1 image
1 list
Research and use other tags, think about what you need to structure the content for your particular site.
As time allows, add more content. Google will be your best friend!
Okay, so our site has good content.
...but it's ugly :(
Let's give it a makeover with CSS!
CSS: Cascading Stylesheets
What is CSS
Adds a presentational layer to our pages.
Provides the browser with rules for how our content should be displayed, by attaching styles to the HTML we write.
All our CSS needs to go in a .css file, and that file be referenced from our HTML.
So fun! Colors, small animations, vector graphics - explore codepen for ideas.

Hex codes: A # plus a 6 digit alphanumeric code. Example: #F2A489
Css Codepen Practice
Add the properties from the previous slide to an h1 tag. Use the example properties, test your own, or look up other properties and values online. (10 minutes)
The class name can be applied to as many elements as you need.

There are pre-written classes and IDs in CSS, we're going to use them on our HTML elements and watch the styling come to life!
Creating Layouts with CSS
The Box Model
Everything is a Box.
Every tag is a Box
Box Model Elements
Property
Description
Border
Every box has a border, even if it’s not visible or specified to be 0px wide.
Margin
Margins sit outside the border. You can set the width of a margin to create space between the borders of two adjacent boxes.
Padding
Every box has a border, even if it’s not visible or specified to be 0px wide.
Block vs. Inline Elements
Block vs. Inline Elements
Block-Level elements will always start on a new line. Examples: h1-h6, ul, li, p, ol, div
Inline elements will continue on the same line as thier other inline neighbors. Examples: a, img, span
Why does box sizing and block vs. inline matter?
When designging layouts in CSS, you need to know the default behavior of your elements in order to make thoughful styling decisions. You're able to override default display with the "box-model" and "display" properties in CSS.
Positioning
Position Property
img {
position: relative;
}
Fixed: Doesn't move when you scroll
Relative: Positioned relative to its default position
Absolute: Similar to fixed, but positioned relative to the window.
See the tutorial for code examples: https://css-tricks.com/almanac/properties/p/position/
Flexbox
nav {
display: flex;
}
Flexbox is a CSS layout mode that provides a more efficient way to lay out, align and distribute space among items in a container, even when their size is unknown and/or dynamic (thus the word "flex").
We have covered A LOT so far today (and have more!), please use this time to apply some of the concepts to your working site. Ideas to get you started...
Add classes and IDs to your element and style them in CSS.
Add a menu with a list of links
Use positioning to "stick" a header to the top or footer to the bottom
Create hover states for links, buttons, images
Dig into CSS documentation
Are you stuck?
Well, this is your life now
I will be walking around to provide hands-on assistance, but try debugging first!
Check your code syntax: do you have semi-colons, space, punctuation in the right place?
Check your spelling: are your class/IDs spelled the same in HTML and CSS?
Think about default inline, block, box-model behavior - refer to documenation
Google your problem, Stack overflow is very helpful
You've Got a website, now what?
Static Site Deployment
Options for Deploying Your Site
Purchase a domain and server space with a web host
Host on Github
Use a static deployment service like Bit Ballon.
Where do I get a domain?
A domain is a registered URL that points to your site files on your server
You pay for domain registration on an annual basis
I like gandi.net and namecheap.com
Why do I need a host?
Your site files need to "live" somewhere in order for everyone to be able to access them.
Different companies have different packages based on storage, number of sites and users.
I'd probably avoid GoDaddy, and I use MediaTemple at the office.
Look for the "Seriously Comprehensive Guide to Choosing a Web Host on webdesign.tutsplus.com.
GIthub.io Site
Github is version control software that allows you to store your code remotely
Github repositories (projects) are essentially project files hosted on github
Github automatically dedicates a specific repo name (yourusername.github.io) to being a publicly accessible site
Follow this tutorial: https://pages.github.com/

Netherlands plans to cut speed limit to curb emissions, rein in pollution
by Travis FedschunGet ready to hit the brakes if you plan on hitting the roads in the Netherlands in the future.
The Dutch government announced Wednesday it is lowering the top speed limit during the day on highways to 62 mph (100km/h) in an attempt to deal with an emissions pollution crisis
The measure followed a Dutch Supreme Court decision in May that said the government's rules for granting permits to projects that emit nitrogen oxide were breaching European Union environmental law. That ruling led to a freeze on permits for many construction projects.
ANGRY DUTCH FARMERS CLOG UP 700 MILES OF HIGHWAY DURING PROTEST OVER EMISSION RULES
Dutch Prime Minister Mark Rutte, whose conservative party is known as the "vroom vroom" party because of its support of motorists, admitted it was a "rotten measure" but necessary.
"No-one likes this," he said at a news conference Wednesday. "But there's really something bigger at stake. We have to stop the Netherlands from coming to a halt and jobs being lost unnecessarily."
The current speed limit of 81 mph (130 km/h) will be retained from 7 p.m. and 6 a.m. under the new plan, which Dutch broadcast NOS reported will be introduced in 2020.
The reduction in the speed limit came after major infrastructure projects across the country were placed on hold in the wake of the court ruling. Government officials wanted to build 75,000 homes next year but spent the last week trying to find a solution to cutting the pollutants, according to the BBC.
Last month, Dutch farmers clogged up nearly 700 miles of major highways across the country when they staged protests over being unfairly blamed for the emissions problem.
BREXIT MAY BRING 'REAL END OF THE BRITISH EMPIRE,' TOP EU OFFICIAL WARNS
Rutte said Wednesday that the important delayed construction projects can resume after the speed limit has been reduced. The law change will now give the Netherlands one of the lowest speed limits in the E.U., according to Deutsche Welle.

The Association of Dutch Car Dealers slammed the plan on Wednesday, saying it will barely lower emissions. Meanwhile, the environmental organization Milieudefensie said the law was "good news for nature and the environment," Deutsche Welle reported.
Fox News' Barnini Chakraborty and the Associated Press contributed to this report.


Trump honors veterans at New York ceremony: 'The glory of your deeds will only grow greater with time'
by Ronn BlitzerPresident Trump honored U.S. veterans and declared it is now the country's duty to "serve and protect them," as he kicked off a ceremony before the 100th New York City Veterans Day Parade on Monday.
The president delivered remarks prior to a wreath-laying ceremony. Accompanied by first lady Melania Trump, he was the first sitting president to attend the event.
12 VETERANS BECOME NATURALIZED US CITIZENS IN CEREMONY ON 'FOX & FRIENDS'
“To each veteran of the war, the glory of your deeds will only grow greater with time,” Trump said, as he honored veterans in attendance, including World War II vets such as one of the parade’s grand marshals, Hershel “Woody” Williams.
And Trump reaffirmed the country's commitment to those who served: “Now it is our duty to serve and protect them.”
The parade is organized by the United War Veterans Council. Trump has been a longtime supporter of the event, with The New York Times reporting that during the 1990s he pledged $200,000 and offered to raise money from friends in exchange for being named the parade's grand marshal at the time.
The president noted Monday that it is fitting that the ceremony and parade take place in New York.
“Since the earliest days of our nation, New York has exemplified the American spirit,” Trump said, recalling New Yorkers who fought in wars going back to the Revolution.
Prominent New Yorkers in attendance included New York City Mayor Bill de Blasio and Senate Minority Leader Chuck Schumer, D-N.Y.
The president also recognized Gold Star Families whose loved ones died for their country.
“To every Gold Star Family, we will stand by your side forever,” the president vowed.

Trump also used the event to tout the strength of the U.S. military and the Oct. 26 death of Islamic State leader Abu Bakr al- Baghdadi, saying "al-Baghdadi is dead. His second in charge is dead. We have our eyes on number 3."

Aaron Connolly An Injury Doubt For Ireland's Upcoming Games
by Robert RedmondAaron Connolly has emerged as an injury doubt for the Republic of Ireland’s upcoming games.
Ireland play New Zealand in a friendly on Thursday before facing Denmark in a crucial Euro 2020 qualifier on November 18, a game they must win to qualify for the tournament next summer.
Both games will be at the Aviva Stadium and Mick McCarthy could be without Connolly for the fixtures.
The Brighton and Hove Albion forward, who made his senior debut for the national team last month, was forced off at half-time against Manchester United on Sunday. Connolly will have a scan on a groin injury on Monday morning before a decision is made on his availability.
“Aaron will have a scan on Monday morning,” McCarthy told the FAI’s website on Sunday evening.
“Our medical team have been in contact with Brighton and when we have the results on Monday, we will know more.”
Connolly has scored three goals in 11 appearances for the Seagulls this season. He netted a brace against Tottenham Hotspur last month in a three-nil win and was subsequently promoted to the Ireland senior squad. Connolly made his Ireland debut in the draw against Georgia before earning his first senior start a few days later in the 2-0 loss to Switzerland.
In a video with the FAI, McCarthy also confirmed that Jack Byrne will feature against New Zealand on Thursday. Byrne was named PFAI Player of the Year on Saturday night for his performances this year for Shamrock Rovers.

Welcome.
I designed and developed this website in pursuit of a change from Operation IT into a more creative role. I want to be a part of the medium that shapes our digital world.I am an artist that started fostering my curiosity in coding.
I will be updating this site periodically as I research, discover, and tinker with new possibilities and concepts.
So please, look at this as a personal/interactive résumé.
Experience
Founder of OwlhelpIT
I currently operate a private IT consulting practice where I provide professional services to small businesses and assist individuals with any ideas they have. I believe that eveyrone deserves the same professional IT guy that companies have.
One of my next projects is to work on getting a site up for OwlHelpIT using BootStrap to gain experience with that framework.
IT Admin for Sinu
I am an IT Amidnistator for a global MSP. There, I handle operational IT for all of Sinu's clientel. My tasks here have mainly been: planning, documentation, remedial IT tasks and implemtation. I have also had the opportunity to do some coding with development of email signatures, lite website editing work and identifying where errors with some sites lie.
IT Manager at DOOR3
DOOR3 was my first real look at website development. It was here that my interest started and I began my journey in coding. I began coding here in between my duties as the single point of contact for any IT related tasks for 90+ employees worldwide. I would handle everything from global DNS, Proxies, VM's, Domain managment, tunnels, documentation and administrative duties, to simple troubleshooting with desktop applications.
Education
General Assembly
In wanting to cement my experience and knowledge in Front End Web Development I enrolled in a part time course.

We need to ask you a few questions to start your appeal.
You will need to:


arcgis.geoanalytics.manage_data module¶
These tools are used for the day-to-day management of geographic and tabular data.
copy_to_data_store copies data to your ArcGIS Data Store and creates a layer in your web GIS.
append_data¶
-
arcgis.geoanalytics.manage_data.
append_data
(input_layer, append_layer, field_mapping=None, gis=None)¶ Only available at ArcGIS Enterprise 10.6.1 and later.
The Append Data task appends tabular, point, line, or polygon data to an existing layer. The input layer must be a hosted feature layer. The tool will add the appended data as rows to the input layer. No new output layer is created.
Argument Description input_layer required FeatureLayer , The table, point, line or polygon features. append_layer required FeatureLayer. The table, point, line, or polygon features to be appended to the input_layer. To append geometry, the append_layer must have the same geometry type as the input_layer. If the geometry types are not the same, the append_layer geometry will be removed and all other matching fields will be appended. The geometry of the input_layer will always be maintained. field_mapping Defines how the fields in append_layer are appended to the input_layer.
The following are set by default:
- All append_layer fields that match input_layer schema will be appended.
- Fields that exist in the input_layer and not in the append_layer will be appended with null values.
- Fields that exist in the append_layer and not in the input_layer will not be appended.
Optionally choose how input_layer fields will be appended from the following:
- AppendField - Matches the input_layer field with an append_layer field of a different name. Field types must match.
- Expression - Calculates values for the resulting field. Values are calculated using Arcade expressions. To assign null values, use ‘null’.
gis optional GIS, the GIS on which this tool runs. If not specified, the active GIS is used. Returns: boolean
calculate_fields¶
-
arcgis.geoanalytics.manage_data.
calculate_fields
(input_layer, field_name, data_type, expression, track_aware=False, track_fields=None, time_boundary_split=None, time_split_unit=None, time_reference=None, output_name=None, gis=None)¶ The Calculate Field task works with a layer to create and populate a new field. The output is a new feature layer, that is the same as the input features, with the additional field added.
Returns: Feature Layer
clip_layer¶
..autofunction:: arcgis.geoanalytics.manage_data.clip_layer
copy_to_data_store¶
-
arcgis.geoanalytics.manage_data.
copy_to_data_store
(input_layer, output_name: str = None, gis=None)¶ Copies an input feature layer or table to an ArcGIS Data Store and creates a layer in your web GIS.
For example
- Copy a collection of .csv files in a big data file share to the spatiotemporal data store for visualization.
- Copy the features in the current map extent that are stored in the spatiotemporal data store to the relational data store.
This tool will take an input layer and copy it to a data store. Data will be copied to the ArcGIS Data Store and will be stored in your relational or spatiotemporal data store.
For example, you could copy features that are stored in a big data file share to a relational data store and specify that only features within the current map extent will be copied. This would create a hosted feature service with only those features that were within the specified map extent.
Parameters:
input_layer: Input Layer (feature layer). Required parameter.
output_name: Output Layer Name (str). Required parameter.
gis: Optional, the GIS on which this tool runs. If not specified, the active GIS is used.
- Returns:
- output - Output Layer as a feature layer collection item
dissolve_boundaries¶
-
arcgis.geoanalytics.manage_data.
dissolve_boundaries
(input_layer, dissolve_fields=None, summary_fields=None, multipart=False, output_name=None, gis=None)¶ The Dissolve Boundaries task finds polygons that intersect or have the same field values and merges them together to form a single polygon.
Examples:
A city council wants to control liquor sales by refusing new licenses to stores within 1,000 feet of schools, libraries, and parks. After creating a 1,000-foot buffer around the schools, libraries, and parks, the buffered layers can be joined together and the boundaries can be dissolved to create a single layer of restricted areas.Usage Notes:
Only available at ArcGIS Enterprise 10.7 and later.
Argument Description input_layer required FeatureLayer. The point, line or polygon features. dissolve_fields Optional string. A comma seperated list of strings for each field that you want to dissolve on. summary_fields Optional list. Calculate one or more statistics for the dissolved areas by using the summary_fields parameter. The input is a list of key/value pairs in the following format:
[{“statisticType” : “<stat>”, “onStatisticField” : “<field name>”}]Allows statistics are:
- Any (string fields only)
- Count
- Sum
- Minimum
- Maximum
- Average
- Variance
- Standard Deviation
Example:
- summary_fields = [{“statisticType” : “Sum”, “onStatisticField” : “quadrat_area_km2”},
- {“statisticType” : “Mean”, “onStatisticField” : “soil_depth_cm”}, {“statisticType” : “Any”, “onStatisticField” : “quadrat_desc”}]
multipart Optional boolean. If True, the output service can contain multipart features. If False (default):, the output service will only contain single-part features, and individual features will be created for each part. output_name optional string. The task will create a feature service of the results. You define the name of the service. gis optional GIS. The GIS object where the analysis will take place. Returns: FeatureLayer
merge_layers¶
-
arcgis.geoanalytics.manage_data.
merge_layers
(input_layer, merge_layer, merge_attributes=None, output_name=None, gis=None)¶ The Merge Layers task combines two feature layers to create a single output layer. The tool requires that both layers have the same geometry type (tabular, point, line, or polygon). If time is enabled on one layer, the other must also be time enabled and have the same time type (instant or interval). The result will always contain all fields from the input layer. All fields from the merge layer will be included by default, or you can specify custom merge rules to define the resulting schema. For example:
- I have three layers for England, Wales, and Scotland and I want a single layer of Great Britain. I can use Merge Layers to combine the areas and maintain all fields from each area.
- I have two layers containing parcel information for contiguous townships. I want to join them together into a single layer, keeping only the fields that have the same name and type in the two layers.
Only available at ArcGIS Enterprise 10.7 and later.
Argument Description input_layer Required FeatureLayer. The point, line or polygon features. merge_layer Required FeatureLayer. The point, line, or polygon features to merge with the input_layer. The merge_layer must contain the same geometry type (tabular, point, line, or polygon) and the same time type (none, instant, or interval) as the input_layer. All fields in the merge_layer will be included in the result layer by default or you can define merge_attributes to customize the resulting schema. merge_attributes Optional list. Defines how the fields in mergeLayer will be modified. By default, all fields from both inputs will be included in the output layer.
If a field exists in one layer but not the other, the output layer will still contain the field. The output field will contain null values for the input features that did not have the field. For example, if the input_layer contains a field named TYPE but the merge_layer does not contain TYPE, the output will contain TYPE, but its values will be null for all the features copied from the merge_layer.
You can control how fields in the merge_layer are written to the output layer using the following merge types that operate on a specified merge_layer field:
- Remove - The field in the merge_layer will be removed from the output layer.
- Rename - The field in the merge_layer will be renamed in the output layer. You cannot rename a field in the merge_layer to a field in the inputLayer. If you want to make field names equivalent, use Match.
- Match - A field in the merge_layer is made equivalent to a field in the input_layer specified by mergeValue. For example, the input_layer has a field named CODE and the merge_layer has a field named STATUS. You can match STATUS to CODE, and the output will contain the CODE field with values of the STATUS field used for features copied from the merge_layer. Type casting is supported (for example, double to integer, integer to string) except for string to numeric.
REST web example:
- Syntax: This example matches Average_Sales to Mean_Sales,
- removesBonus, and renamesField4 to Errors.
- [{
- “mergeLayerField”: “Mean_Sales”, “mergeType”: “Match”, “mergeValue”: “Average_Sales”
}, {
“mergeLayerField”: “Bonus”, “mergeType”: “Remove”,}, {
“mergeLayerField”: “Field4”, “mergeType”: “Rename”, “mergeValue”: “Errors”}]
output_name Optional string. The task will create a feature service of the results. You define the name of the service. gis Optional GIS. The GIS object where the analysis will take place. Returns: FeatureLayer
overlay_data¶
-
arcgis.geoanalytics.manage_data.
overlay_data
(input_layer, overlay_layer, overlay_type='intersect', output_name=None, gis=None)¶ Only available at ArcGIS Enterprise 10.6.1 and later.
Argument Description input_layer required FeatureLayer. The point, line or polygon features. overlay_layer required FeatureLayer. The features that will be overlaid with the input_layer features. overlay_type optional string. The type of overlay to be performed. Values: intersect, erase
- intersect - Computes a geometric intersection of the input layers. Features or portions of features that overlap in both the inputLayer and overlayLayer layers will be written to the output layer. This is the default.
- erase - Only those features or portions of features in the overlay_layer that are not within the features in the input_layer layer are written to the output.
- union - Computes a geometric union of the input_layer and overlay_layer. All features and their attributes will be written to the layer.
- identity - Computes a geometric intersection of the input features and identity features. Features or portions of features that overlap in both input_layer and overlay_layer will be written to the output layer.
- symmetricaldifference - Features or portions of features in the input_layer and overlay_layer that do not overlap will be written to the output layer.
output_name optional string. The task will create a feature service of the results. You define the name of the service. gis optional GIS. The GIS object where the analysis will take place. Returns: FeatureLayer
run_python_script¶

arcgis.geoanalytics.manage_data.
run_python_script
(code, layers=None, gis=None)¶ The run_python_script method executes a Python script on your ArcGIS GeoAnalytics Server site. In the script, you can create an analysis pipeline by chaining together multiple GeoAnalytics Tools without writing intermediate results to a data store. You can also use other Python functionality in the script that can be distributed across your GeoAnalytics Server.
For example, suppose that each week you receive a new dataset of vehicle locations containing billions of point features. Each time you receive a new dataset, you must perform the same workflow involving multiple GeoAnalytics Tools to create an information product that you share within your organization. This workflow creates several large intermediate layers that take up lots of space in your data store. By scripting this workflow in Python and executing the code in the Run Python Script task, you can avoid creating these unnecessary intermediate layers, while simplifying the steps to create the information product.
When you use Run Python Script, the Python code is executed on your GeoAnalytics Server. The script runs with the Python 3.6 environment that is installed with GeoAnalytics Server, and all console output is returned as job messages. Some Python modules can be used in your script to execute code across multiple cores of one or more machines in your GeoAnalytics Server using Spark 2.2.0(the compute platform that distributes analysis for GeoAnalytics Tools).
A geoanalytics module is available and allows you to run GeoAnalytics Tools in the script. This package is imported automatically when you use Run Python Script.
To interact directly with Spark in the Run Python Script task, use the pyspark module, which is imported automatically when you run the task. The pyspark module is the Python API for Spark and provides a collection of distributed analysis tools for data management, clustering, regression, and more that can be called in Run Python Script and run across your GeoAnalytics Server.
When using the geoanalytics and pyspark packages, most functions return analysis results in memory as Spark DataFrames. Spark data frames can be written to a data store or used in the script. This allows for the chaining together of multiple geoanalytics and pyspark tools, while only writing out the final result to a data store, eliminating the need to create any intermediate result layers.
For advanced users, an instance of SparkContext is instantiated automatically as sc and can be used in the script to interact with Spark. This allows for the execution of custom distributed analysis across your GeoAnalytics Server.
It is recommended that you use an integrated development environment (IDE) to write your Python script, and copy the script text into the Run Python Script tool. This makes it easier to identify syntax errors and typos prior to running your script. It is also recommended that you run your script using a small subset of the input data first to verify that there are no logic errors or exceptions. You can use the Describe Dataset task to create a sample layer for this purpose.
code Required String/Python Method. Python code to execute. layers Optional List. A list of FeatureLayers to operate on. gis optional GIS. The GIS object where the analysis will take place. Returns: Dictionary of messages from the code provided.

[dscrdeql] <KQweci-Mod> Have a good one @SwimedDragon
[dscrdeql] <Jellysmash> good night to you @SwimedDragon
[dscrdeql] <Jellysmash> chat later
GatewayBOT13-Aug-18 11:00 PM
[dscrdeql] <Steve10> Hey I finally got some btc into exrates. See that the lowest buy is 16 SATs and sells are at 168. Does exrates penalize you if you cancel an order? Want to get a low ball order in but if it never fills I want to cancel w/o penalties
[dscrdeql] <Buddz1993> Good night fellows
[dscrdeql] <c2k> no they dont penalize you
[dscrdeql] <Buddz1993> In staying asleep
[dscrdeql] <c2k> you just need to go to the "orders" tab and cxl it
[dscrdeql] <c2k> no penalty
[dscrdeql] <c2k> @Steve10
[dscrdeql] <c2k> there are plenty of bids lower.
[dscrdeql] <c2k> we were talking a lot about it a few hrs ago
[dscrdeql] <c2k> how people are looking to scoop up 6-7figs 10sats or below
[dscrdeql] <Steve10> Ok thanks. What's the chances of those 16 and under being filled? Seems hard to imagine them being filled
[dscrdeql] <c2k> so my guess is it doesnt get there
[dscrdeql] <c2k> can leeave it in for a few hours and see what happens
[dscrdeql] <c2k> cant imagine if you dont buy them you would have to pay more than 20sats to get filled
[dscrdeql] <Steve10>
GatewayBOT13-Aug-18 11:31 PM
[dscrdeql] <Jonathan-Mod> Evening folks, I see tipsy has evolved
[dscrdeql] <Jellysmash> The new tipsy
[dscrdeql] <Jellysmash> I've adjusted my buy orders up now
[dscrdeql] <Jonathan-Mod> Yep, knew it was coming today just didn't know when
[dscrdeql] <Jellysmash> ..still under 10 sats....I'm a stinge
[dscrdeql] <Jellysmash> Never know if the dumper will have one last hurray(edited)
[dscrdeql] <Biomech-Founder> LOL
[dscrdeql] <Biomech-Founder> Oh, I got a buy or two on that myself
[dscrdeql] <Jellysmash> Good bless a dumper......until our bags are full and bulging(edited)
[dscrdeql] <Jellysmash> Then ....kill the dumper.....lol
[dscrdeql] <Jellysmash> Need to get enough for a few masternodes
GatewayBOT13-Aug-18 11:57 PM
[dscrdeql] <RyanInSiam> Good morning from sleepy Bangkok! How's everyone doing?
[dscrdeql] <Buddz1993> Morning still sleepy here but I need to sleep still ahah
[dscrdeql] <Buddz1993> You ?:D
[dscrdeql] <RyanInSiam> Bit sleepy myself. Going to wash some dishes and make some tea here at the office.
GatewayBOT14-Aug-18 12:05 AM
[dscrdeql] <akomismo> Have a reset for all???
[dscrdeql] <Buddz1993> Great plan
[dscrdeql] <Buddz1993> Yes for all
[dscrdeql] <akomismo> Aw
GatewayBOT14-Aug-18 12:23 AM
[dscrdeql] <Jellysmash> @RyanInSiam hey they're
[dscrdeql] <Jellysmash> Yep doing well
[dscrdeql] <Jellysmash> Sunny day in Sydney
[dscrdeql] <RyanInSiam> What's going on, @Jellysmash ?
[dscrdeql] <Jellysmash> Beautiful
[dscrdeql] <Jellysmash> I'm at work
[dscrdeql] <Jellysmash> So have to do a bit of chat on the lowdown
[dscrdeql] <Jonathan-Mod> Man I need a passport, too many places I want to visit
[dscrdeql] <edsky> What’s been happening guys ive been bust renovating the last week
[dscrdeql] <Jellysmash> Yes, worlds a bit beautiful place(edited)
[dscrdeql] <Jellysmash> So many good places
[dscrdeql] <RyanInSiam> Yeah, I'm at the office too.
[dscrdeql] <Jellysmash> @edsky hey
[dscrdeql] <Jellysmash> Going ok
[dscrdeql] <edsky> Sorry busy
[dscrdeql] <Jellysmash> New baselined levels for us(edited)
[dscrdeql] <edsky> How you doing @Jellysmash
[dscrdeql] <Jellysmash> Start all over
[dscrdeql] <Jellysmash> It's fun
[dscrdeql] <Jellysmash> Whoa....leveled up
[dscrdeql] <Jellysmash> Noice
[dscrdeql] <RyanInSiam> Leveled up but will lose that soon, eh?
[dscrdeql] <Buddz1993> Congrats
[dscrdeql] <Buddz1993> leveling is easier now
[dscrdeql] <edsky> No @RyanInSiam I think reset has happened
[dscrdeql] <RyanInSiam> Already? Guess I'm still catching up on messages here.
[dscrdeql] <RyanInSiam> My bad.
[dscrdeql] <Buddz1993> Yep reset has happened already
[dscrdeql] <Buddz1993> Top 100 will to achieve level 5 get flooded with rain for 24 hours I think
[dscrdeql] <c2k> now that buddz is at level 5
[dscrdeql] <c2k> we wont hear from him for a month
[dscrdeql] <c2k> lololol
[dscrdeql] <Buddz1993> rofl ahaha
[dscrdeql] <Buddz1993> I won’t be like that
[dscrdeql] <c2k> somwhow this new setup caused a rainstorm
[dscrdeql] <c2k> people cant stop raining
[dscrdeql] <Buddz1993> I need to get to level 15
[dscrdeql] <Buddz1993>
[dscrdeql] <c2k> i was just kidding buddz
[dscrdeql] <edsky> Its good yah
[dscrdeql] <c2k> for sure...and fast
[dscrdeql] <Buddz1993> But this system has improved things
[dscrdeql] <Buddz1993> In my opinion
[dscrdeql] <RyanInSiam> What kind of changes did we get?
[dscrdeql] <c2k> if it gets more people involved then yes
[dscrdeql] <c2k> @RyanInSiam the founders moved everyone back to level 1
[dscrdeql] <c2k> and started over
[dscrdeql] <c2k> and are giving "rain" incentives
[dscrdeql] <c2k> once you reach level 5
[dscrdeql] <RyanInSiam> Yeah, that much I saw.
[dscrdeql] <c2k> so some of us still have "titles"
[dscrdeql] <RyanInSiam> Was just curious what other changes to the system there were?
[dscrdeql] <c2k> but we all start over on level 1
[dscrdeql] <Buddz1993> Yep exactly like she said
[dscrdeql] <Jellysmash> I think it's a very interesting way

pip_services3_commons.errors.ApplicationException.
ApplicationException
(category='Unknown', correlation_id=None, code='UNKNOWN', message='Unknown error')¶ Bases:
Exception
Defines a base class to defive various application exceptions.
Most languages have own definition of base exception (error) types. However, this class is implemented symmetrically in all languages supported by PipServices toolkit. It allows to create portable implementations and support proper error propagation in microservices calls.
Error propagation means that when microservice implemented in one language calls microservice(s) implemented in a different language(s), errors are returned throught the entire call chain and restored in their original (or close) type.
Since number of potential exception types is endless, PipServices toolkit supports only 12 standard categories of exceptions defined in ErrorCategory. This ApplicationException class acts as a basis for all other 12 standard exception types.
Most exceptions have just free-form message that describes occured error. That may not be sufficient to create meaninful error descriptions. The ApplicationException class proposes an extended error definition that has more standard fields:
- message: is a human-readable error description
- category: one of 12 standard error categories of errors
- status: numeric HTTP status code for REST invocations
- code: a unique error code, usually defined as “MY_ERROR_CODE”
- correlation_id: a unique transaction id to trace execution through a call chain
- details: map with error parameters that can help to recreate meaningful error description in other languages
- stack_trace: a stack trace
- cause: original error that is wrapped by this exception
ApplicationException class is not serializable. To pass errors through the wire it is converted into ErrorDescription object and restored on receiving end into identical exception type.
