20 Essential Tips and Tricks for Google’s Pixel 4 and 4 XL
by Peter HoldenPhones and their features get more complicated every year, with gestures for this, squeezes for that, and multiple swipes and taps needed for numerous other functions. You may have just spent the mortgage money on your new Pixel 4 or Pixel 4 XL, but are you making the most of your handset, or have you barely scratched the surface of your new phone’s potential? The combination of Android 10 and Google’s latest Pixel phones means that there are a ton of new features to discover, so why not make it easy on yourself and join us after the break for these twenty essential tips and tricks for the Pixel 4 and Pixel 4 XL.
Enable Dark Mode
Possibly the most requested feature for Stock Android in the past 18 months is Dark Mode, which is finally a system-wide setting in Android 10. Now there is no need to be blinded at night when looking at the shiny brightness of Material Design.
- Open up Settings
- Tap on Display
- Toggle Dark Theme on or off
Enable Developer Options
There are some features and options that you can only access by enabling Developer Options, so we’ve included the steps to do so below. It’s important to remember that enabling or disabling any of the settings could cause issues, so be warned. If you do choose to enable the Developer Options, always take note of the option you are altering so that you can quickly return to the default setting if things don’t go as planned. If you are absolutely sure, you can follow the directions below
- Open up Settings and select System
- Tap on About Phone
- Scroll down to Build Number and tap it seven times
- You’ll be asked to enter your PIN to continue (If you’ve already set one up)
- You are now a developer! (No, not really)
- Return to Settings and select System
- Tap on Advanced, and the Developer Options tab will show just about System Update
Force Dark Mode everywhere and on everything
This is a brute force setting for those of us that want everything everywhere to switch to dark mode, whether the app supports it or not. Be warned; it can have unintended consequences with some apps appearing a little unusual. You will need to enable the Developer Options to access the function.
- Open up Settings
- Scroll down and select System
- Tap on Advanced and then Developer Options
- Scroll down to Hardware Accelerated Rending
- Tap on Override Force-Dark
Disable Motion Sense
Motion Sense is a great feature that turns on the display every time your hand goes near the phone. While it’s fun wafting your hand in the air to change songs for a while, it’s a gimmick you may want to disable after a while. Disabling it also helps to save battery life.
- Head to Settings
- Tap on System
- Select Motion Sense
- Choose whether to disable the functions one-by-one or Motion Sense as a whole
Set-up Face Unlock
Seeing as Google chose to eschew the addition of a fingerprint reader on the Pixel 4 series, your options when it comes to securing your handset and unlocking it are limited to entering PINs, patterns, and Face Unlock. Setting up Face Unlock is relatively easy; all you need to do is follow the steps below:
- Open up Settings and select Security
- Tap on Face Unlock
- Select Set up Face Unlock
- Read the guidelines and press Next
- Tap on Start and then fit your face in the inner frame
- Rotate your face, capturing all the angles of your face by removing the tiles in the frame
- Press Done when complete
Change from Gestures to 3-button navigation
If controlling the Pixel 4 with the gestures found in Android 10 isn’t to your liking, switching back to the legacy 3-button setup of Back, Home, and Recent is a simple process.
- Open up Settings
- Scroll down and select System
- Tap on Gestures
- Select System Navigation
- Choose between Gesture navigation or 3-Button navigation
Disable Active Edge
First seen on the HTC U11, Active Edge is one of those features that you will use all the time or not at all. Follow the steps below to customize the Active Edge functions and the squeeze sensitivity or to disable it altogether.
- Open up Settings and select System
- Tap on Gestures and then Active Edge
- Adjust the squeeze sensitivity to your liking
- Toggle the Allow when the Screen is Off and Squeeze for Silence functions
- Choose to disable Active Edge by toggling all functions to the off position
Enable Jump to Camera
When your phone is in your pocket, and you need to take a photo of the memory unfolding in front of you, you don’t always have time to unlock the Pixel 4 and open up the Camera app manually. Luckily, you can open the camera in a split second by pressing the Power button twice in quick succession.
- Open up Settings and select System
- Tap on Gestures and then Jump to Camera
- Toggle the Jump to Camera function on or off
Schedule Do Not Disturb
Whether you are in an important meeting or want some peace and quiet, the Do Not Disturb function is handy, ensuring that your phone doesn’t make unwanted sounds or vibrations at inconvenient times.
- Head to Settings and tap on Sound
- Select Do Not Disturb
- Choose whether or not to accept calls from a specific group of people or no one
- Choose to allow calls, texts, and messaging apps from contacts starred contacts, or no one at all
- Choose whether to restrict just sound and visual notifications
- Tap on Custom to further customize the Do Not Disturb function
- Select Default Duration to enable Do Not Disturb indefinitely or for a specific time
- Click on Schedules to set Do Not Disturb to turn on and off at particular times on particular days
Schedule Night Light to turn on
Looking at displays in dim light can strain your eyes, but you can ease the effect by enabling Night Light, which will tint your screen amber. You can turn it on or off or adjust the intensity of the effect to suit your liking.
- Open up Settings and tap on Display
- Click on Night Light
- Choose to turn it on and adjust the intensity
- Click on the Schedule button to turn Night Light on automatically from sunset to sunrise or at specific times of the day
Set a bedtime schedule with Wind Down
Sometimes it’s challenging to pull yourself away from the smartphone. Still, if you think you need help to move your attention away from your new Pixel 4 gradually, then the new Wind Down feature will help you disconnect from the handset and avoid interruptions while you sleep.
- Head to Settings and select Digital Wellbeing
- Click on Wind Down
- Toggle Wind Down on
- Choose what time and which days you want Wind Down to activate and when to end
- Choose to enable Grayscale and Do Not Disturb
- Coordinate Wind Down with your Night Light schedule (if you’ve set one up)
Stop app icons being added to the Home Screen
When you first download an app from the Play Store, your Pixel 4 is set to automatically place the app icons on the home screen, which can look a little messy. Follow the directions below to ensure that app icons are no longer added to the home screen.
- Long-press in an empty area of the home screen
- Choose Home Settings
- Toggle the Add icon to Home Screen option off
- You’ll need to manually remove any app icons that have been added to the home screen
Enable Screen Attention
If you hate your phone’s display going to sleep at inopportune times, then you’ll need to enable the Screen Attention feature that will prevent the display turning off if the front camera detects that you are looking at the phone.
- Open Settings and tap on Display
- Click on Screen Attention
- Tap the toggle to turn the feature on
Enable Smooth Display
While enabling Smooth Display to boost the refresh rate up to 90Hz means that battery life will take a small hit, the slick user experience it provides should not be understated. For the moment, at least, though, enabling the feature will only affect selected content.
- Head to Settings and tap on Display
- Click on Smooth Display
- Toggle the feature on
Show LockDown option on Power Menu
Security is a serious topic, and if you ever find yourself in a situation where you need to lock your phone down in a split-second, then having the option to on the power menu is going to be extremely useful.
- Open up Settings and select Security
- Tap the gear icon on Screen Lock
- Click on the Power Button Instantly Locks toggle
Turn on Now Playing
Not knowing who created the awesome song that is playing in the coffee shop can be frustrating, but not when you have the Now Playing feature enabled on the Pixel 4 that shows the song title and band details.
- Head to Settings and click on Display
- Scroll down and tap on Lock Screen Display
- Click on Now Playing
- Choose to display the song details on the lock screen
- Choose to show the details in the notifications shade
Turn on Flip to Shhh
If you don’t want to take a call in a meeting and forgot to enable Do Not Disturb, have no worries because you can choose to turn the phone face down on a flat surface to mute the incoming call.
- Open Settings and tap on System
- Click on Gestures
- Tap on Flip to Shhh
- Click the toggle to enable the feature
Enable Live Caption
Live Caption is one of those features that you’ll wonder how you lived without, especially if you are in the habit of forgetting to charge your headphones for those YouTube videos on the commute to work or when you can’t listen to a voice message. Live Caption will automatically create captions for the media playing on your Pixel 4, including podcasts, videos, and audio messages.
- Open up the Settings app
- Click on Sound and then Live Capture
- Choose to enable Live Capture
- Select whether to show profanities, to show sound labels such as applause or laughter
- Choose to display the Live Capture icon in the volume controls
Turn on Data Saver
If you are in the habit of running out of data before your allowance refreshes, you may want to activate the Data Saver option on the Pixel 4 that will prevent some apps from sending or receiving data in the background.
- Open Settings and click on Network & Internet
- Tap on Data Saver
- Toggle Data Saver on
- Click on Unrestricted Data to choose specific apps to exclude from being restricted
Force 90Hz refresh everywhere
If, after enabling Smooth Display, you were disappointed that you weren’t getting the full 90Hz experience in every single app, you can choose to force the higher refresh rate by digging around in Developer Options. Again, it should be noted that fiddling with Developer Options can result in the Pixel 4 experiencing issues, so be absolutely sure that you want to enable 90Hz and also that you are tapping on the correct setting.
- Open Settings and select System
- Tap on Advanced
- Click on Developer Options
- Scroll to Debugging and toggle the Force 90Hz Refresh Rate on

Tutorial 4 - Concerns
In this tutorial we refactor the mixin from the previous steps so that the result of the say() method
is modified to be prefixed with "Simon says:". To do this we need to implement a Concern for
the say() method. Concerns are a type of Modifier which modify the behaviour of
the methods in Mixins. They do this by intercepting the invocation of the TransientComposite. This allows
them to change the invocation parameters, return their own values or throw their own exceptions,
and do other things which directly affect the invocation of the method.
Concerns should not perform any side-effects, such as updating state in another TransientComposite, Mixin
or similar. Any side-effects are done in SideEffects, which is another type of Modifier, which are
allowed to perform side-effects but, in contrast to Concerns, cannot change the parameters or
in any other way change the result of the invocation.
Concerns are implemented in one of two ways: either create a class which directly implements
the interface whose methods should be modified, or create a generic Modifier by implementing
the InvocationHandler interface (or subclass GenericConcern which does this for you).
Add an @ConcernFor dependency injection, as a field, constructor parameter or method parameter,
which has the same type as the interface the Concern implements. When the TransientComposite is invoked
the Concern will be called, allowing it to perform it's work. If the call should proceed, then
invoke the method again on the injected object. The preferred way to do all of this is to subclass
ConcernOf which does all of this for you.
Concerns are applied by adding an @Concerns annotation on the TransientComposite, the domain interface,
or the Mixin implementation. Any of these works, and where to put it is a matter of design choice.
Steps for this tutorial:
- Create a typed concern, implement the HelloWorldBehaviour and let it modify the result
of the base method by prefix the result with "Simon says:".
- Add an @Concerns annotation on the HelloWorldBehaviourMixin which references the Concern class.

| Value: | [ [<uri> ,]* [ auto | crosshair | default | pointer | move | e-resize | ne-resize | nw-resize | n-resize | se-resize | sw-resize | s-resize | w-resize | text | wait | help | progress ] ] | inherit |
| Initial: | auto |
| Applies to: | all elements |
| Inherited: | yes |
| Percentages: | N/A |
| Media: | visual, interactive |
| Computed value: | as specified, except with any relative URLs converted to absolute |
This property specifies the type of cursor to be displayed for the pointing device. Values have the following meanings:
:link,:visited { cursor: url(example.svg#linkcursor), url(hyper.cur), pointer }
This example sets the cursor on all hyperlinks (whether visited or not) to an external SVG cursor. User agents that do not support SVG cursors would simply skip to the next value and attempt to use the "hyper.cur" cursor. If that cursor format was also not supported, the UA would skip to the next value and simply render the 'pointer' cursor.
Note. The System Colors are deprecated in the CSS3 Color Module [CSS3COLOR].
In addition to being able to assign pre-defined color values to text, backgrounds, etc., CSS2 introduced a set of named color values that allows authors to specify colors in a manner that integrates them into the operating system's graphic environment.
For systems that do not have a corresponding value, the specified value should be mapped to the nearest system value, or to a default color.
The following lists additional values for color-related CSS properties and their general meaning. Any color property (e.g., 'color' or 'background-color') can take one of the following names. Although these are case-insensitive, it is recommended that the mixed capitalization shown below be used, to make the names more legible.
For example, to set the foreground and background colors of a paragraph to the same foreground and background colors of the user's window, write the following:
p { color: WindowText; background-color: Window }
As for colors, authors may specify fonts in a way that makes use of a user's system resources. Please consult the 'font' property for details.
At times, style sheet authors may want to create outlines around visual objects such as buttons, active form fields, image maps, etc., to make them stand out. CSS 2.1 outlines differ from borders in the following ways:
The outline properties control the style of these dynamic outlines.
| Value: | [ <'outline-color'> || <'outline-style'> || <'outline-width'> ] | inherit |
| Initial: | see individual properties |
| Applies to: | all elements |
| Inherited: | no |
| Percentages: | N/A |
| Media: | visual, interactive |
| Computed value: | see individual properties |
| Value: | <border-width> | inherit |
| Initial: | medium |
| Applies to: | all elements |
| Inherited: | no |
| Percentages: | N/A |
| Media: | visual, interactive |
| Computed value: | absolute length; '0' if the outline style is 'none' |
| Value: | <border-style> | inherit |
| Initial: | none |
| Applies to: | all elements |
| Inherited: | no |
| Percentages: | N/A |
| Media: | visual, interactive |
| Computed value: | as specified |
| Value: | <color> | invert | inherit |
| Initial: | invert |
| Applies to: | all elements |
| Inherited: | no |
| Percentages: | N/A |
| Media: | visual, interactive |
| Computed value: | as specified |
The outline created with the outline properties is drawn "over" a box, i.e., the outline is always on top, and does not influence the position or size of the box, or of any other boxes. Therefore, displaying or suppressing outlines does not cause reflow or overflow.
The outline may be drawn starting just outside the border edge.
Outlines may be non-rectangular. For example, if the element is broken across several lines, the outline is the minimum outline that encloses all the element's boxes. In contrast to borders, the outline is not open at the line box's end or start, but is always fully connected if possible.
The 'outline-width' property accepts the same values as 'border-width'.
The 'outline-style' property accepts the same values as 'border-style', except that 'hidden' is not a legal outline style.
The 'outline-color' accepts all colors, as well as the keyword 'invert'. 'Invert' is expected to perform a color inversion on the pixels on the screen. This is a common trick to ensure the focus border is visible, regardless of color background.
Conformant UAs may ignore the 'invert' value on platforms that do not support color inversion of the pixels on the screen. If the UA does not support the 'invert' value then the initial value of the 'outline-color' property is the value of the 'color' property, similar to the initial value of the 'border-top-color' property.
The 'outline' property is a shorthand property, and sets all three of 'outline-style', 'outline-width', and 'outline-color'.
Note. The outline is the same on all sides. In contrast to borders, there is no 'outline-top' or 'outline-left' property.
This specification does not define how multiple overlapping outlines are drawn, or how outlines are drawn for boxes that are partially obscured behind other elements.
Note. Since the outline does not affect formatting (i.e., no space is left for it in the box model), it may well overlap other elements on the page.
Here's an example of drawing a thick outline around a BUTTON element:
button { outline : thick solid}
Scripts may be used to dynamically change the width of the outline, without provoking a reflow.
Graphical user interfaces may use outlines around elements to tell the user which element on the page has the focus. These outlines are in addition to any borders, and switching outlines on and off should not cause the document to reflow. The focus is the subject of user interaction in a document (e.g., for entering text, selecting a button, etc.). User agents supporting the interactive media group must keep track of where the focus lies and must also represent the focus. This may be done by using dynamic outlines in conjunction with the :focus pseudo-class.
For example, to draw a thick black line around an element when it has the focus, and a thick red line when it is active, the following rules can be used:
:focus { outline: thick solid black }
:active { outline: thick solid red }
The CSS working group considers that the magnification of a document or portions of a document should not be specified through style sheets. User agents may support such magnification in different ways (e.g., larger images, louder sounds, etc.)
When magnifying a page, UAs should preserve the relationships between positioned elements. For example, a comic strip may be composed of images with overlaid text elements. When magnifying this page, a user agent should keep the text within the comic strip balloon.

Sainz unable to set Brazil F1 qualifying time after wiring issue
by Adam CooperMcLaren Formula 1 driver Carlos Sainz will start from the back of the grid in Brazil after an ignition wiring issue during qualifying caused a loss of power.
Sainz slowed to a crawl and retreated to the pits during the opening stages of Q1, and was classified last during the session having been unable to set a lap time.
Renault traced the source of the problem after the session, but no decision has been taken on whether the Spaniard will take any new components.
He has a high-mileage "Friday" engine that was used on Friday, but as he starts at the back of the grid there would be no extra penalty if he takes a new power unit.
The team also has the option to make changes to the specification of the car - such as taking out drag to make it easier to overtake - which would lead to a pitlane start.
"It's still open at the moment," said McLaren team boss Andreas Seidl. "We still need to figure out what we want to do, what were the consequences.
"And we also have a first analysis now, which means that the wiring system of the of the ignition failed and that was causing a power loss Carlos felt and nothing we could fix."
Sainz admitted that managing his tyres would be the biggest issue as he tries to make progress through the field.
"It's maximum attack I guess," he said.
"Obviously, maximum attack doesn't always work with Pirelli tyres. So it will be a compromise between managing the tyres and going maximum attack. So it's probably a very difficult thing to do, but somehow you must always find a way."
Sainz's team-mate Lando Norris could manage only 11th place after a clean qualifying session, indicating a drop-off in McLaren's form compared to recent races.
"I guess we've seen some trends this year in some tracks that there are certain types of corners where we are not very strong," explained Sainz.
"And probably this track has many of those types of corners.
"That's why your relative performance drops depending on track to track, but also it doesn't mean that we cannot make it to the points.
"It just means that it's going to be probably a lot tougher, or tougher than Austria, for example, where it was a good one.
"But it doesn't mean that we cannot do it. It just means that we need to do better."


Lexical Format¶
Characters¶
The text format assigns meaning to source text, which consists of a sequence of characters. Characters are assumed to be represented as valid Unicode (Section 2.4) code points.
Tokens¶
The character stream in the source text is divided, from left to right, into a sequence of tokens, as defined by the following grammar.
Tokens are formed from the input character stream according to the longest match rule. That is, the next token always consists of the longest possible sequence of characters that is recognized by the above lexical grammar. Tokens can be separated by white space, but except for strings, they cannot themselves contain whitespace.
The set of keyword tokens is defined implicitly, by all occurrences of a terminal symbol in literal form, such as \(\def\mathdef2706#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef2706{keyword}\), in a syntactic production of this chapter.
Any token that does not fall into any of the other categories is considered reserved, and cannot occur in source text.
Note
The effect of defining the set of reserved tokens is that all tokens must be separated by either parentheses or white space. For example, \(\def\mathdef2707#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef2707{0\$x}\) is a single reserved token. Consequently, it is not recognized as two separate tokens \(\def\mathdef2708#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef2708{0}\) and \(\def\mathdef2709#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef2709{\$x}\), but instead disallowed. This property of tokenization is not affected by the fact that the definition of reserved tokens overlaps with other token classes.
White Space¶
White space is any sequence of literal space characters, formatting characters, or comments. The allowed formatting characters correspond to a subset of the ASCII format effectors, namely, horizontal tabulation (\(\def\mathdef2710#1{\mathrm{U{+}#1}}\mathdef2710{09}\)), line feed (\(\def\mathdef2711#1{\mathrm{U{+}#1}}\mathdef2711{0A}\)), and carriage return (\(\def\mathdef2712#1{\mathrm{U{+}#1}}\mathdef2712{0D}\)).
The only relevance of white space is to separate tokens. It is otherwise ignored.
Comments¶
A comment can either be a line comment, started with a double semicolon \(\def\mathdef2681#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef2681{{;}{;}}\) and extending to the end of the line, or a block comment, enclosed in delimiters \(\def\mathdef2679#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef2679{{(}{;}} \dots \def\mathdef2680#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef2680{{;}{)}}\). Block comments can be nested.
Here, the pseudo token \(\mathtt{eof}\) indicates the end of the input. The look-ahead restrictions on the productions for \(\href{../text/lexical.html#text-comment}{\mathtt{blockchar}}\) disambiguate the grammar such that only well-bracketed uses of block comment delimiters are allowed.
Note
Any formatting and control characters are allowed inside comments.


Developed as a part of semester long project for User Interface Design and Development class in a team of five with Andrew Wu, Molly Mahar, Pooja Jain and Astika Gupta.
The Problem statement driving this project was "How to help Berkeley students finance better?"
We started out the process by outlining the major questions we wanted answers to, like do students budget at all? If they do, what tools do they use? Are their any difficulties they face with these tools? Where are the information gaps? Do students of different age group and nationality think differently about money? To get answers to these questions we conducted several interviews. We focused on covering as many distinct groups of students as possible and tried to understand their frustrations around money matters. Based on the interviews, we designed four personas based on the level of planning students do to manage their finances.
Next in the design process we made several lo-fi prototype keeping in mind the goals of our primary persona. We tested different versions of the lo-fi prototype and collected feedback from the target users. BAsed on these feedback we designed a few versions of interactive prototypes adn tested it more. By this point, we were able to flesh out the components we wanted to keep in our final version of the tool based on all the feedback we had recieved. These would solve the problems of our primary personas without completely ignoring the secondary ones.
Based on the work done on all the previosuse prototype we developed a hi-fi prototype of the tool. We conducted qualitative and quantitative usability tests on our hi-fi prototype to fully understand whats working and whats not in order to improve the tool in future versions.

kml.transfer
Transfer one figure axes to kml file as an image overlay.
Contents
Syntax
kml.transfer(axisHandle) kml.transfer(...,'PropertyName',PropertyValue,...)
Description
kml.tranfer(axisHandle) will save the axis represented by the handle axisHandle as an image, and place this image as a ground overlay in the kml file, using the axis limits to position the overlay (x axis -> longitude / y axis -> latitude).
The axis units will normaly be treated as degrees, but this can be changed by calling: kml.useDegrees; or kml.useRadians; before transfering the axis.
To make the overlay transparent, change the alpha portion of the color parameter to a different hex value - eg.: 50% transparent, use kml.transfer(...,'color','80FFFFFF')
It is possible to fine tune the overlay properties using name-value pairs:
kml.transfer(...,'PropertyName',PropertyValue,...)
Properties
| Property Name | Type | Description |
|---|---|---|
| 'name' | string | Name of the overlay in the kml file |
| 'id' | string | Internal id of this overlay inside the kml |
| 'description' | string | A short description of what the overlay represents |
| 'visibility' | true/false | Control the initial visibility of the overlay |
| 'transparentBG' | true/false | Remove the background of the axis, in order to preserve only the plot. |
| 'keepAxis' | true/false | If set to true, keep the axes when saving the image. Otherwise, they are removed in the image |
| 'inPlace' | true/false | If set to true, the axes will not be cloned into a new figure before plotting. This can be useful if the plot to be transfered is too heavy, but be careful that plot will erased after calling kml.transfer |
| 'color' | kml color string | Defines the color of the overlay. Must be a valid hex color string input, in the style AABBGGRR |
| 'altitude' | double | Altitude where the overlay should be plotted. Input in meters. |
| 'altitudeMode' | string | Choose if the altitude value is absolute to the earth model, relative to the ground level, or should be clamped to the ground. Valid inputs: 'absolute', 'relativeToGround', 'clampToGround' |
| 'drawOrder' | double | In case more than one overlay is placed in the same location, this input defines the order on which they should be draw. |
| 'rotation' | double | Specifies a rotation of the overlay about its center. Values can be ±180° or ±pi, depending on the active unit. The default is 0 (north). Rotations are specified in a counterclockwise direction. |
| 'timeStamp' | kml date string | Associates the polygon to a moment in time. Should not be used together with timeSpan. Should be a string in the XML time format (more information available here) |
| 'timeSpanBegin' | kml date string | Defines the moment in time where the polygon starts to exist. Should not be used together with timeStamp. Should be a string in the XML time format (more information available here) |
| 'timeSpanEnd' | kml date string | Defines the moment in time where the polygon finishes to exist. Should not be used together with timeStamp. Should be a string in the XML time format (more information available here) |
Example

Adaptive cards ✓
We have utilised adaptivecards.io design unique card designs to display data in a user friendly and intuitive way. We have found, through user testing, that the current design choice of our adaptive cards are the easiest and quickest way to gain relevant information on any number of categories.
Parser for IXN Forms ✓
We have created a program which takes in a .docx file as input and extracts all of the essential information from it and uploads it to a database hosted on azure. The IXN miner employs algorithms which check for duplication of fields and also finds the rows in the column which most match the column headings in the database.
Administrator panel ✓
We have firstly created an ixn miner which parsers .docx IXN filse and extracts relevant information and uploads it to the relative databases. In order to make this parser more easily usable by someone who will actually need to use it, we designed an administrator panel using tkinter, this panel allows for step by step guidance for adding new projects to the database and also updating existing information.
Luis machine learning: ✓
We have integrated luis with our project in order to parse the users messages and determine the intent of their message as well as the ability to identify keywords in their messages that would aid in construction of SQL queries so that the most relevant results can be displayed with absolute minimised clutter and ease of use.
Fuzzy string matching ✓
We have utilised the "fuzzywuzzy" python library in order to aid in the parsing of the IXN forms incase fields were mispelt, as mistakes can happen with the best of us, but that doesnt mean that they should be made public on the database, so we do our best to essentially spell check our users.
Microsoft bot Framework ✓
We chose to use the Microsoft Bot Framework to host our chatbot as it was a comprehensive and easy-to-use SDK (Software Development Kit) comprised of the framework itself and also the bot connector SDK. The Microsoft Bot Framework allows for a high degree of customisation, many integration possibilities, developer friendly testing with an emulator. There were also a range of predefined, customisable classes and functions. The downside of using this framework is that it could take a lot of over-complicated code for even the simplest of logic. Having worked with the Microsoft Bot Framework we do not regret our choice as it allowed for a very large amount of customisation. We especially liked the ability to integrate our own adaptive card templates.

Distributed Security Guidelines
Several techniques can enhance the security of distributed DB2 implementations. The following guidelines will assist the developer in securing distributed DB2 data.
Come-From Checking
At times, ensuring that a specific userid has the appropriate authorization to access distributed data is not sufficient. Using the CDB tables, you can use DB2 to institute what is known as come-from checking. When come-from checking is established, the requesting location and requesting userid are checked in combination.
Suppose that userid DBAPCSM exists at several locations:
CHICAGO, JACKSONVILLE, andPITTSBURGH. By populating the SYSIBM.USERNAMES table appropriately, you can implement come-from checking to effectively disable specific combinations of userid and location.
By inserting the appropriate rows into SYSIBM.LUNAMES and SYSIBM.USERNAMES, you can implement come-from checking to enable a specific user to access data from any location or to enable any user to access data from a specific location. By default, come-from checking is not implemented. Analysis and specific action must be taken to use come-from checking.
Come-from checking is particularly useful when multiple authids may be logging in from multiple locations. Additional control is available with come-from checking.
Authid Translation
Another possibility in a distributed environment is to translate authids automatically for distributed requests. One authid can be translated to another completely different authid.
Authids can be translated by the requesting location, the server location, both locations, or neither location.
Inbound authid translation happens when authids are translated by the server. This term is used because the authid is not changed until it is received by the server (as an inbound request). By contrast, outbound authid translation is performed by the requester, prior to the request being sent.
Consistent Authids
You can use authid translation to implement consistent authids for each user on the network, regardless of location. Consider, for example, a situation in which authids are assigned so that they are unique across the network. Perhaps the location is embedded in the name. So, maybe DBAPCSM exists in Pittsburgh; DBAJCSM, in Jacksonville; and DBACCSM, in Chicago.
Authid translation can be used to convert any of these valid authids to a single, consistent authid such as DBACSM. Doing so greatly reduces the administrative burden of implemented distributed security.
Network Specific Authids
Sometimes assigning all requests from a single location the same consistent authid is useful. If you impose outbound authid translation, all outbound requests can be translated to one specific authid, thereby reducing complexity (of course, at the expense of security).
Password Encryption
If outbound authid translation is implemented, DB2 requires that a valid password is sent along with each authid. If you choose this option, be sure to encrypt the passwords in the SYSUSERNAMES CDB table using one of the following methods:
Miscellaneous Security Guidelines
Utilize the following security guidelines as you develop distributed DB2 applications.
PUBLIC AT ALL LOCATIONS
If a particular table is to be made accessible by anyone on the networkóregardless of authid or locationósecurity can be granted specifying PUBLIC AT ALL LOCATIONS. Of course, it is applicable to only the INSERT, UPDATE, DELETE, and SELECT table privileges.

The documentation for this class was generated from the following file:


First, two heuristic observations:
- The Linux binaries runs measurably faster than the Windows one.
- Out of the three compilers on Linux tested (GCC, Clang, ICC), Clang seems to produce faster code.
Compiler Options
- I recommend the following compiler options (GCC, Clang):
-O3 -march=native
- For safety you can use -fsanitize=signed-integer-overflow that checks for integer overflow at minimum performance cost. For extra safety, -fsanitize=integer checks all kinds of unwanted integer behavior (eg unsigned overflow) at a slightly higher cost. More generally -fsanitize=undefined can be used to check for all undefined behavior (and more) at a much greater performance hit (about 10x slower).
- See this page for compiler options regarding Eigen.
- If OpenMP support is desired use
-fopenmp
.
Multithreading
- The main algorithms of the program are single-threaded, with the idea being that they will be performed in loops, computing the answer in a range (which is required for the identification algorithms to then work). Multithreading these loop iterations with openMP is turned on by default in the
AdditiveStructure
and Factorization
code, using the maximum amount of threads available. But note that other parts of the library (using std::map
) are not thread-safe and need to be locked; thankfully these have almost no bearing on performance.
- There is one caveat: While the loop iterations are independent, they are not all equally computationally intensive. A sphere like \(S^{2\sigma+\lambda}\) is cheaper to compute compared to \(S^{6\sigma+8\lambda}\) which is in turn much cheaper compared to \(S^{6\sigma-8\lambda}\) as the latter one involves a box product. In the multiplicative structure we may have to take double box products, and these are even more expensive in run-time as they involve arbitrarily large permutation matrices.
- So it's important to equally divide the work among the threads. Currently this has to be done manually on the user's end.
Dense vs Sparse
- Dense matrices are faster than sparse matrices as long as they don't get too large.
- When matrices do get large, sparse matrices not only offer better performance, but huge savings in memory (30x and above). When triple box products are used in combination with dense matrices and multithreading, memory usage can go up to 60GB, hitting the swap file and slowing the program to a crawl. In that case we can see up to 20x speedup when using sparse matrices. The Intel MKL is not any faster than Eigen for sparse matrix multiplication.
Box Products
Box products involve some very large matrices, and the more iterated box products we use the higher that complexity.
where \(V=V_{pos}-V_{neg}\)
- For the multiplicative structure we need to take an extra box product, so up to three total when computing \(ab\) for \(a,b\) in the mixed homology.
- For factorization we would also need three box products. But by design, we are only multiplying with certain basic irreducibles (Euler and orientation classes) and hope everything else is obtained like this. By selecting them to be in the pure co/homology (which the Euler and orientation classes always are) we can reduce this to two box products total. If extra identification needed then we do take triple box products, incurring a massive performance and memory cost.
- For Massey products we need an extra two box products, so up to five total then computing \(\langle a,b,c\rangle \) for \(a,b,c\) in the mixed homology.

Cpp-Taskflow
2.2.0

This page summarizes a list of frequently asked questions about Cpp-Taskflow. If you cannot find a solution here, please post an issue at here.
Cpp-Taskflow aims to help C++ developers quickly implement efficient parallel decomposition strategies using task-based approaches.
Cpp-Taskflow is a header-only library with zero dependencies. The only thing you need is a C++17 compiler. To use Cpp-Taskflow, simply drop the folder taskflow/
to your project and include taskflow.hpp.
Static tasking refers to those tasks created before execution, while dynamic tasking refers to those tasks created during the execution of static tasks or dynamic tasks (nested). Dynamic tasks created by the same task node are grouped together to a subflow.
Benchmarks showed Cpp-Taskflow can efficiently handle millions or billions of tasks (both large and small tasks) on a machine with up to 64 CPUs.
The hex value represents the memory address of the task. Each task has a method tf::Task::name(const std::string&) for user to assign a human readable string to ease the debugging process. If a task is not assigned a name or is an internal node, its address value in the memory is used instead.
Unfortunately, Cpp-Taskflow is heavily relying on modern C++17's features/idoms/STL and it is very difficult to provide a version that compiles under older C++ versions.
Cpp-Taskflow has implemented different scheduler modules (centralized queue, proactive shceduler, speculative strategy, and work stealing). The default scheduler implements the famous work stealing algorithm that has shown to behave efficiently in most multicore architectures. You can find the source code at taskflow/threadpool/workstealing_threadpool.hpp
The master thread owns the thread pool and can spawn workers to run tasks or shutdown the pool. Giving taskflow N
threads means using N
threads to do the works, and there is a total of N+1
threads (including the master threads) in the program.
If there is no worker threads in the pool, the master thread will do all the works by itself. Please refer to Master, Workers, and Executor for more details.
The lifetime of a task sticks with its parent graph. A task is not destroyed until its parent graph is destroyed. Please refer to Lifetime of A Task for more details.
No, the taskflow object is not thread-safe. You can't create tasks from multiple threads at the same time.
When the program hangs forever it is very likely your taskflow graph has a cycle. Try the tf::Taskflow::dump method to debug the graph before dispatching your taskflow graph.
No. The subflow is spawned during the execution of B, and at this point A must finish because A precedes B. This gives rise to the fact B1 and B2 must run after A. This graph may looks strange because B seems to run twice! However, Cpp-Taskflow will schedule B only once to create its subflow. Whether this subflow joins or detaches from B only affects the future object returned from B.

Water simulation has a long history in computer graphics and has attracted hundreds of researchers. But the main reason it has fascinated me is the various phenomenon that occurs in a liquid like water like reflections, refractions, waves or even splashes. The major inspiration arose from Evan Wallace’s water rendering. There are various techniques to simulate water. I considered water as a planar mesh to triangles and distorting the mesh or the textures for various effects.
VR simulation for people with certain anxiety disorders in professional settings, such as speaking in front of a group at work or attending an interview. We see a large number of people with such issues and this project is to help them:
This project was completed in collaboration with Shreyas Iyer.

Variant management consists of two main components:
fdp-variant-management-wrapper
fdp-variant-management
Wrapper component listens to the preset changes in components, thus, it should wrap all
PresetManagedComponent
components.
Renderer component can be placed anywhere on the page, and the instance of it should be passed back to the Wrapper component.
For the cases when Renderer component is placed inside Wrapper component and
reachable with @ContentChild
decorator, Wrapper will automatically find it, so users don't need to
pass it instance directly.
Developers can define custom Author name via [userName]
input property.
Variant object contains of data
property, which should contain key-value object, where key is the
preset-managed component name, and the value is actual preset configuration.
In case variant management is used with multiple identical components, component's name can be set individually
via [name]
Input property.
Variant Management component supports configuring all table properties such as: search, filters, columns, pagination, grouping, sorting.
Variant Management component can also be used inside Dynamic Page component.
Please note: if you have multiple controlled components inside Dynamic page in different sections (header, content, etc.), you would need to wrap whole dynamic page in order for all components to be recognized.


Week 1

I've learned so much this week that it's almost overwhelming. But, here are some key takeaways that I want to remember.
Version control is a tool that keeps record of changes and different versions of code at different times. GitHub helps especially with version control especially when multiple people are working on the same code. It funnels “parallel universes” that are simultaneously keeping track of their own changes and people can then “push” or “pull” these versions to the master code at their choosing without messing up the original code.
Git tracks changes through detecting updates made in your local computer. It then asks you to save it, or "commit" it, taking a snapshot of the code at that moment in time. You can then command git to push those changes onto the remote copy online on GitHub.
GitHub is an amazing community of developers collaborating and learning from each other. GitHub allows this to happen by providing a space for collaborators to work on the same project simultaneously without messing up the master code and feeding off of each other.

While computers can help us manage data, human judgment and domain expertise is what turns it into understanding. Meeting the challenges of increasingly large and complex data requires methods that richly integrate the capabilities of both people and machines. In response to these challenges, this thesis contributes new languages and models for visualization design that power interactive systems for scalable data analysis.
In these languages, users can be imprecise about low-level design decisions as the system leverages this ambiguity to optimize the visual design and necessary computation. Vega-Lite is a high-level declarative language for rapidly creating interactive visualizations, while also providing a convenient yet powerful representation for tools that generate visualizations. Vega-Lite uses smart defaults to fill in low-level details to create eective designs. The declarative design facilitates optimization of the required data processing. Draco is a model of visualization design that extends Vega-Lite with shareable design guidelines, formal reasoning over the design space, and visualization recommendation. We show how we can use Draco to construct increasingly sophisticated automated visualization design and recommendation systems, including systems based on weights learned directly from the results of graphical perception experiments.
We take a user-centric perspective on systems for scalable exploratory analysis. Considering both the backend and frontend concerns, we present Falcon, an interactive crossfilter application where users can interact with billions of records without latencies that negatively affect their exploration. To scale beyond billions of records, we present Pangloss, a visual analysis system that uses approximate query processing but provides eventual guarantees using Optimistic Visualization. In this concept, we treat approximate query processing as a user experience problem to address users' primary concern: trust in their exploration results. Falcon and Pangloss contribute techniques for scalable interaction and exploration of large data volumes by making principled trade-os among people's latency tolerance, precomputation, and the level of approximation.

DREAM LOVER A film review by Ridgeje Copyright 1994 Ridgeje
FILM: Dream Lover CAST: James Spader, Madchen Amick, Bess Armstrong DIRECTOR: Nicholas Kazan SCREENPLAY: Nicholas Kazan RUNNING TIME: 1:43 RELEASE: May 6, 1994
"You're a psychopath."
"Psychopaths can love people, too. Can't they?"
The directorial debut of Nicholas Kazan stars James Spader as an architect in search of happiness, and the above is between him and what he's settled for. By that point in the film, Ray has had his life turned upside down, inside down, inside out--but that's jumping a bit too far ahead yet.
The film's start finds Ray in the midst of divorce from the wife he found in bed with another man. He'd be the first to admit divorce isn't what he wants--and the feeling is mutual, it would seem, as his unfaithful wife (who was only looking for a reason to leave their marriage) tells him: "I know you'll find the right person, and when you do, she'll be the luckiest woman alive"--but Ray has never been very good at containing his anger (especially under those circumstances), and ultimately struck his wife.
Time passes, and his friends feel it time for Ray to start a new life, with a new woman. Ray agrees: "I want the kids, the dog, the Volvo," but would be satisfied if everyone just left him alone while finding these things. Namely, the wife part. That doesn't stop a business colleague/best friend (Larry Miller) from hooking him up with a ditsy broad, anyway, whom Ray encounters at a party. "We're practically engaged," she tells him, which doesn't make him all that happy. What Ray really needs is the right woman--the perfect woman--to give him the life he wants and get the friends, who only want the best for him, off his back. Salvation comes (well, maybe) in the form of Lena, whose nice dress Ray ruins with a clumsy wine spill. He offers to help her clean up, but she's clearly pissed beyond the point of reprieve ... or, at least, to engage in polite conversation.
Their second encounter proves a bit more fruitful when Ray runs into Lena while shopping at a grocery store. He is taken aback by her beauty (as are we).  He takes her to dinner, she tells him her interests in life, and then walks her to her apartment where he ends up spending the night. He's hooked. Problem is Ray can't find his one-nighter afterwards and so, like a lover confused, he stalks her apartment, waiting outside to finally see her ... with another man, who Lena is quick to explain is only a "friend."
Before she has the chance to get away from him again, Ray married this sensuous woman he hasn't taken the time to know anything about. They're very happy for a while, too, matching sexual drives pound for pound, and have a child together. He's in love with her, his friends love her; it's all so perfect. Too perfect. This is one mysterious lady Ray's decided to spend his life with, but it takes him a while to see past the facade that's blinded him and wake up to the lies she's feeding him. Easy to see why; as Ray tells a friend (the friend who may, in fact, be sleeping with his new bride): "The most gorgeous creature I've ever seen, and she chose me." When suspicions do arise withing Ray that perhaps Lena has been as untruthful as any one person can be with another, he simply forgets it all and loses himself in her beauty. Even when he overhears her immersed in flirtatious phone talk, Ray continues putting aside any good judgment aside. He should know better.
Eventually Ray hits his wife (again) ... and then hits her harder. The "I bruise easy" BS she gave Ray comes back to haunt him with a vengeance when he's committed to a mental institution for wife-beating. Ray denies emphatically having inflicted the injuries that can so vividly be seen on Lena's face; he appears cool, calm, collected and completely in a healthy state of mind until other people start lying on his wife's behalf. That sets him off, spewing profanities left and right and putting up fight with security. Ray is there to stay.
The woman responsible for tearing this Everyman apart with her bare hands is Lena (Thelma/Sissy), and she is played by Madchen Amick. She is drop-dead gorgeous, using her sexuality to get exactly what she wants from men. Her latest innocent devises a plan to get back at her and then ending, when that plan comes to head, is a genuine surprise. Not because of what takes place, but because of the rationale behind it--Kazan's screenplay finds a way for Ray to get revenge, while pointing a finger at the irony involved with the court system in America concurrently. It's brilliant; a real surprise. Lena gets what she deserves, leading us to assume that eventually Ray will, too.
Kazan directs Spader and Amick the way you'd expect a first-timer to: professionally, but not exceptionally. We get a lot of eye close-ups that would seem to give some sort of dark insight as to what's going on within the heads of these people. We can tell by looking at Spader's face exactly what Ray is feeling, so seeing his eyes enlarged on-screen makes them bigger, not anymore meaningful. Kazan's script isn't anything all that fresh, just an outline of thriller cliches. And as a thriller, DREAM LOVER is notably a low-key film.
What makes it all work are the two stars at play. James Spader is an interesting young actor, at times giving a concentrated stare that suggests pain, frustration, anger, and subtle attraction all at once. He always seems to have more than one thing on his mind, and feels one step ahead of the audience even when the screenplay calls for him not to be. Spader is quite good at portraying more feeling than the film really deserves, and aside from JACK'S BACK, I'm not sure he's been this good.
At the opposite end is Amick, who isn't all that competent an actress, but passable as the femme fatale. She pinpoints Lena's angle right off, playing it sweet and relaxed during the first third of the movie--like a confident sexpot would--and becoming less so toward the end. She even starts enjoying herself as Lena lets her true colors shine: After Ray punches her in the face, she sits up with a grin and says, "Is that all?" But we understand all of this; Amick never moves on. If nothing more, you may be intrigued to simply look at her; she truly is smashing. Both she and Spader look great in the film, so credit the make-up and costume designers for doing a bang-up job. In face, while watching DREAM LOVER, I found myself examining the actors' (just the leads) faces and not thinking a lot about what was going on around them. Their scenes together are sexy and believable and well-performed.
But I believe I've hit upon something else. It's probably best to not take under consideration the majority of what happens in DREAM LOVER--no one involved with the project did. We find out that Lena is not he housewife Ray wants, but a woman with a specific purpose. She even asks Ray to give her credit for becoming a different person because in Lena's opinion, not many people could do with their lives what she's done with her own. Ray isn't concerned with philosophy; all he wanted was to be in love and have children with a wife. That's why what finally happens is more damaging for Ray that for Lena.
It isn't a complicated process, but the film isn't ever boring, either. It could've been executed more successfully; Director Kazan would perhaps have had a better film on his hands having wiped out a few of the dream sequences in translation of script to screen; the sequences are excessive and pointless (there are four long ones), and one too many uninvolving scenes linger. Overall, though, what's here makes for a serviceable little erotic mystery that is marvelous to look at.
Forget the plot. Feast your eyes on Spader and the heart-stoppingly beautiful Madchen Amick. Two actors never looked this good in a movie.
